Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to chemical production technical field, concretely relates to a dustproof composite calcium carbide crusher. BACKGROUND
[0002] In the production process of PVC by calcium carbide method, in order to ensure that calcium carbide is completely hydrolyzed, the acetylene generating post first carries out artificial crushing to blocky calcium carbide with a particle size of ≤600mm, the calcium carbide is crushed by a jaw crusher, and then is sent to a coarse hopper elevator by a belt conveyor, the material is sent to a coarse material bin by the coarse hopper elevator, the coarse material bin is protected by nitrogen, and the requirements are that the oxygen (O2) content is less than 1%, and the acetylene (C2H2) content is less than 0.5%, the calcium carbide (CaC2, particle size ≤50mm) in the coarse material bin is sent to a composite crusher by a disc feeder, the crushed calcium carbide is lifted into a drum screen by a mixing hopper elevator, and after screening, is added into an acetylene generator to carry out a hydrolysis reaction.
[0003] In the current production process, because the hardness of calcium carbide is relatively high, the composite crusher vibrates greatly during operation, the components of the shell sealing part are prone to loosening, a large amount of dust is released during crushing, there is a large amount of dust-like calcium carbide in the composite crusher during operation, the dust-like calcium carbide is suspended dust, the sealing difficulty is relatively large, the crusher plant environment is poor, the dust is easy to cause damage to surrounding electrical instruments and equipment, meanwhile, the calcium carbide dust is a flammable and dangerous chemical product in a humid environment, there is a risk of fire and explosion, and the on-site operator not only has a safety hazard, but also causes serious harm to the skin, respiratory tract and eyes. CONTENT OF THE UTILITY MODEL
[0004] The utility model provides a dustproof composite calcium carbide crusher to solve the problem that a large amount of dust is easily generated during the crushing of calcium carbide at present, which seriously affects the staff and the operation plant environment.
[0005] The technical scheme of the utility model is as follows: a dustproof composite calcium carbide crusher, comprising a crusher body, a jacket, the jacket is installed outside the crusher body, a pressure gauge is arranged on the jacket, a nitrogen pipeline is connected to the jacket, and a nitrogen regulating valve is arranged on the nitrogen pipeline.
[0006] As a further improvement of the utility model, the nitrogen regulating valve and the pressure gauge are respectively connected to a PLC controller, and the PLC controller can monitor the nitrogen pressure in the jacket at any time during operation.
[0007] The utility model discloses an external jacket is arranged to the compound breaker, and nitrogen is supplemented to the jacket, and nitrogen causes the pressure to the compound breaker, and the compound breaker is sealed, and the dustiness electric stone is not shaken to the breaker plant with the work of compound breaker, and the PLC controller is simultaneously arranged, and according to the pressure gauge information, the opening and closing of nitrogen regulating valve are controlled, and nitrogen pressure is adjusted in time, and the normal work of compound breaker is avoided to be influenced, the utility model discloses simple structure, and the pressure of nitrogen to compound breaker is regulated through the PLC controller, and the compound breaker reaches the sealing effect, and the health of staff and the environment of operating plant are greatly improved. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 It is structural schematic diagram of the utility model.
[0009] In the drawing: 1 - breaker body, 2 - transmission motor, 3 - feed inlet, 4 - breaker discharge port, 5 - breaker rotation unloading valve, 6 - jacket, 7 - nitrogen regulating valve, 8 - pressure gauge, 9 - PLC control system, 10 - nitrogen pipeline. DETAILED DESCRIPTION
[0010] The utility model will be further explained in detail in combination with the drawings and specific embodiment.
[0011] As Figure 1 Shown, a dustproof compound calcium carbide breaker, including breaker body 1.
[0012] A dustproof compound calcium carbide breaker further includes jacket 6, and the jacket 6 is installed in the breaker body 1 outer four quarters, and the jacket 6 is equipped with pressure gauge 8, and the jacket 6 is further connected with nitrogen pipeline 10, and the nitrogen pipeline 10 is equipped with nitrogen regulating valve 7.
[0013] Nitrogen regulating valve 7 and pressure gauge 8 are connected on PLC controller 9 respectively, when nitrogen pressure in jacket 6 is less than 50Kpa, nitrogen regulating valve 7 is automatically opened, when nitrogen pressure in jacket 6 is more than 70Kpa, nitrogen regulating valve 7 is automatically closed.
[0014] When using, first, open the transmission motor 2 on the breaker body 1, make the breaker body 1 begin to work, open the feed inlet 3 on the breaker body 1, and the big piece of electric stone is put into compound breaker 1, and after putting, close the feed inlet 3, avoid that the dustiness electric stone leaks to the air from the feed inlet 3, open the breaker discharge port 4 and breaker rotation unloading valve 5, after starting to produce material, open the jacket nitrogen regulating valve 7, adjust PLC controller 9, control nitrogen pressure through pressure gauge 8 and maintain 50Kpa-70Kpa, when nitrogen pressure in jacket 6 is less than 50Kpa, nitrogen regulating valve 7 is automatically opened, when nitrogen pressure in jacket 6 is more than 70Kpa, nitrogen regulating valve 7 is automatically closed.
