This Part is identical with ISO 5036 “Continuous mechanical handling equipment for loose bulk materials Vertic
14、al screw conveyors Safety code”, developed by Technical Committee ISO/TC 101, Continuous mechanical handling equipment. This Part, which forms one of a series, implements the safety code and should be read in conjunction with BS 5667-1. Terminology and conventions. The text of the International Stan
15、dard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following. The comma has been used throughout as a decimal marker. In Br
16、itish 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 Standard”. Cross-references. The following International Standards are referred to
17、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 responsible for their correct application. Compliance with a British Standard does

21、e This International Standard specifies, in addition to the general safety rules set out in ISO 1819, the special safety rules for the following continuous mechanical handling equipment for loose bulk materials: vertical screw conveyors.1) 2 Field of application The safety rules laid down in this In
22、ternational Standard apply regardless of the use for which the equipment is intended. These safety rules limit the suppliers responsibility to continuous mechanical handling equipment properly so called, excluding the structures to which such equipment is fixed. 3 References ISO 1819, Continuous mec
23、hanical handling equipment Safety code General rules. ISO 2148, Continuous handling equipment Nomenclature. 4 Special safety rules The construction and operation of vertical screw conveyors shall meet the legal and local requirements relating to safety in general (see Appendix Z of ISO 1819); the pr
24、inciples laid down in clause 1 of ISO 1819; the general rules laid down in clause 2 of ISO 1819; the following special rules. 4.1 In the construction stage (design and manufacture) 4.1.1 Upper openings of troughed appliances shall be guarded, apart from feed and discharge areas. 4.1.2 The opening of
25、 covers, inspection doors and the covers of such protective devices as are liable to expose the screw elements while the machinery is in operation shall be prevented by means of locking. Should the user notify the constructor in writing that he intends to allow the opening of inspection doors or suc
26、h protective devices as are liable to expose the screw elements while the machinery is in operation, fixed guards must be provided to prevent any contact with the screw elements. For example, a screen with openings not exceeding 40 mm 40 mm should be fitted at a minimum distance of 100 mm from the s
27、crew edge. 4.1.3 Inlet and outlet apertures shall be so designed as to prevent free access to moving parts. Otherwise, provision shall be made for suitable protective guards. 4.1.4 Lubrication of intermediate screw bearings shall be possible without removing the trough or cover of conveyors. 4.1.5 F
28、or cleaning purposes, removable protective panels shall be fitted on the base of conveyors. 4.1.6 Should a screw conveyor be required to convey dangerous or harmful products, the user shall notify the constructor and specify what special safety features are needed in the design of the equipment. For
29、 example where the possibility of fire or explosion exists, the pitch of the intermediate bearings shall ensure that the screw cannot touch the inside of the casing. 4.2 During the installation stage (layout, erection and entry into service) 4.2.1 Screw conveyors shall be fed regularly by appropriat
30、ely designed devices. 4.2.2 If the vertical screw conveyor is equipped with a hand-operated variable-speed drive, and if the controls are more than 1,5 m above operating level, a fixed means of access shall be provided. 4.3 During the utilization stage (operation and maintenance) 4.3.1 In compliance
31、 with the existing regulations and according to the requirements stated in rule 4.1.2, the personnel shall not be allowed to clean the inside of the trough or carry out any other inspection therein without first having stopped the screw and rendered the starting devices inoperative. 4.3.2 However, s
32、hould the screw conveyor fail to start again normally due to blockage, it shall be possible to reverse it. 4.3.3 Free access to the unprotected rotating part of a screw shall be forbidden to all persons other than the supervisory and maintenance personnel. No action shall be taken by the latter with
33、out having first stopped the screw and taken all precautions to prevent it being prematurely started up. 1) See 2.14.14 of ISO 2148.
