This Part is identical with ISO5029 “Continuous mechani
13、cal handling equipment for loose bulk materials Storage equipment fed by a pneumatic handling system Safety code”, developed by Technical Committee ISO/TC101, Continuous mechanical handling equipment. This Part, which forms one of a series, implements the safety code and should be read in conjunctio
14、n with BS5667-1. Terminology and conventions. The text of the international standard has been approved as suitable for publication, without deviation, as a BritishStandard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn
15、to the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be interpreted as “British Stan
16、dard”. Cross-references. The following international standards are referred to in the text and for each there is a corresponding British Standard; these are as listed below: A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are resp
17、onsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

20、neral safety rules set out in ISO1819, the special safety rules for storage equipment for loose bulk materials fed by a pneumatic handling system. 2 Field of application The safety rules laid down in this International Standard apply regardless of the use for which the equipment is intended. These s
21、afety rules limit the suppliers responsibility to continuous mechanical handling equipment properly so called, excluding the structures to which such equipment is fixed. 3 References ISO1819, Continuous mechanical handling equipment Safety code General rules. ISO5028, Continuous mechanical handling
22、equipment for loose bulk materials Pneumatic handling installations Safety code. 4 Special safety rules The construction and operation of storage equipment for loose bulk materials fed by a pneumatic handling system shall meet the legal and local requirements relating to safety in general (seeAppend
23、ix Z of ISO1819); the design rules for containers under pressure not submitted to the action of flame; 1) the principles laid down in clause1 of ISO1819; the general rules laid down in clause2 of ISO1819 and in ISO5028; the following special rules. 4.1 In the construction stage (design and manufactu
24、re) 4.1.1 Bins, bunkers, silos and hoppers 4.1.1.1 The components must be so designed as not only to carry the stipulated loads (dead weights, stored material, ancillary superstructures, occasional overloads, etc.and if necessary climatic overloads) but also to withstand the maximum permissible pres
25、sure or vacuum. 4.1.1.2 When feeding is by blowing, if the permissible pressure in the storage receptacles is lower than the maximum pressure which may be supplied by the installation, the components should be equipped with appropriate devices allowing the rapid discharge of the whole of the conveyi
26、ng air when the pressure rises to a value which is higher than the permissible pressure. 4.1.1.3 When feeding is by suction, if the permissible vacuum in the storage receptacles is less than the maximum possible vacuum which may be created by the installation, the components shall be equipped accord
27、ingly so as to prevent the increase of the vacuum beyond the permissible limit. 4.1.1.4 Stability under all load conditions must be ensured. 4.1.1.5 If the material stored is reclaimed by vehicles or other moving equipment, the following minimum clearances must be left between the supporting structu
28、res and the vehicles or other moving equipment: 0,5 m for any fixed isolated obstacle less than0,3 m wide as measured in the direction of the movement of the equipment (post, pile, column, angle of building, etc.); 0,7 m for a fixed continuous obstacle (wall, warehouse, wharf, building,etc.). 4.1.1.
29、6 According to the nature of the product, the design of storage receptacles, particularly the slopes of the walls and the position and size of discharge openings, must be such as to ensure a satisfactory flow of the product by gravity, with or without the help of auxiliary equipment. In particular,
30、storage equipment for materials which could form vaults shall be provided with equipment for breaking the latter. Interior struts, interior ladders and other interior components must be avoided to the greatest possible extent. 4.1.1.7 Bins, bunkers, silos and hoppers intended for use with dry combus
31、tible materials must be constructed of fireproof materials. 4.1.1.8 When bins, bunkers, silos and hoppers are more than1,50m deep, risk of workers being buried under products or sinking into them must be prevented and, in particular, inspection doors and detachable parts of bins, bunkers, silos and
32、hoppers must be fitted with a lock and key enabling them to be locked. 4.1.2 Bin gates Bin gates shall be so designed as to ensure satisfactory tightness for the material considered. 4.2 During the installation stage (layout, erection and entry into service) 4.2.1 Bins, bunkers, silos and hoppers 4.
33、2.1.1 Arrangements must be made to stop feeding bins, bunkers, silos and hoppers when the maximum capacity is reached. 1) Seethe corresponding national regulations.BS5667-3:1979 2 BSI 06-1999 4.2.1.2 If there are any hazards of fire or explosion due to the presence of gas, dust or dangerous mixtures
34、, auxiliary installations (lighting,etc.) shall comply with the rules covering such hazards. 4.2.1.3 In order to ensure compliance with the requirements of rule4.1.1.5, the following provisions should be made: a) if the equipment travels on fixed tracks, these tracks should be laid to provide the re
35、quired minimum clearances; b) where steerable vehicles are used, special devices such as bollards, island plinths or continuous curbs should be provided to meet these requirements. 4.2.1.4 The discharge of material and gas from the safety devices must be made to areas not easily accessible to operat
36、ing personnel. 4.2.2 Bin gates Bin gate controls, whether manually or mechanically operated, shall be easily accessible, remote from any hazard of material, and also remote from traffic lanes. 4.3 During the utilization stage (operation and maintenance) 4.3.1 Bins, bunkers, silos and hoppers must no
37、t be used for storing materials the characteristics of which are different from those of the products for which they are designed, without the manufacturers consent. 4.3.2 Access to the inside of bins, bunkers, silos and hoppers should be prohibited and notice of this prohibition should be prominent
38、ly displayed. Where it is necessary for personnel to enter the bins, bunkers, silos and hoppers, special precautions should be taken, including the use of safety equipment, and the individual entering the equipment should be under continuous observation; notices to this effect should be prominently
39、displayed. In all cases where keys are provided, they should be held by the responsible person. 4.3.3 The working order of the safety devices controlling the pressure and vacuum (safety valves, bursting disks,etc.) shall be regularly checked. 4.3.4 When feeding is by blowing and when there is a filt
40、er on the air exhaust, the amount of clogging of the filter must be regularly checked so that the resulting increase of pressure will not lead to an unacceptable over-pressure in the bunker or silo.BS5667-3:1979 BSI 06-1999 Publications referred to See national forewordBS5667-3: 1979 ISO 5029: 1977
