Description

Technical Field

[0001] The invention relates to the technical field of canned chlorine supply equipment, in particular to a fully automatic canned chlorine supply line. Background Art

[0002] As is known to all, in the field of calcium chloride production technology, chlorine is usually supplied in a canned structure in a gaseous state; when the existing chlorine is supplied, it is first fixed on a bracket, and the chlorine tank and the installation joint are fixed together through a manual installation structure, and the gas supply is realized after the valve is opened. However, this supply method has many disadvantages, which are reflected in the following points:

[0003] 1. In the existing automatic feeding system for canned chlorine, external personnel need to use lifting equipment to lift the chlorine tank, and then use lifting equipment to lift the chlorine tank to the work station. This operation has a large workload and there are certain safety hazards in the chlorine supply area;

[0004] 2. The existing chlorine supply tanks do not have automatic weighing devices. After the chlorine tanks are fixed, they can only be checked regularly by personnel. Because the chlorine supply area is dangerous, there are safety hazards when personnel frequently enter;

[0005] 3. When the chlorine tank is replaced, a small amount of chlorine will leak. Currently, there is no dedicated recovery device, so it can only leak into the atmosphere, affecting environmental safety;

[0006] 4. When chlorine is in use and there is a safety leak in the chlorine tank or joints and it cannot be remedied in a short time, the chlorine tank can only be placed in a pool. The current treatment method is to dig a pool deep on the ground in the chlorine supply area. When a safety hazard occurs, the operator will lift the chlorine tank into the pool to prevent the spread of chlorine. However, this operation method is relatively cumbersome, inefficient and poses a safety hazard to the lives of operators.

[0007] In view of the shortcomings of the existing technology, as a technician in this industry, how can we improve the technology and design a new fully automatic supply line for canned chlorine? Through the design of the new structure, the chlorine tank can be automatically moved to the work station and automatically withdrawn. At the same time, it can realize automatic weighing, collection and treatment of waste gas, and automatic water dropping function of the chlorine tank in critical situations.

[0035] On the weighing module 2, a fixing groove 26 is arranged at its front end, and a moving block 27 is inserted in the fixing groove 26. The moving block 27 of the present invention is a triangular structure, which is hinged and fixed at the corner by a moving block fixing shaft 28. After being hinged and fixed, the moving block 27 can be moved in and out of the fixing groove 26 to realize the horizontal fixing of the weighing module. The present invention discloses the specific structure of driving the moving block 27 as follows: after the moving block 27 is fixed on the work surface in a hinged form, a guide wheel 29 is arranged on the front side of the moving block 27, one end of a traction steel cable is fixed on the moving block 27, and the other end of the traction steel cable bypasses the guide wheel and is connected to an external driving device to realize the driving of the moving block. The external driving device described here can be a manual or foot-operated push rod, or a driving cylinder and a variety of structures that can pull the traction steel cable; further extended, the traction steel cable can be horizontally extended to the front side of each weighing module 2 and connected to the moving block 27 on each weighing module 2 to realize linkage and realize the joint driving of the moving blocks 27 on all weighing modules 2.

[0036] With the above structural arrangement, the chlorine tank 11 is placed on the top of the weighing module 2. The weighing module 2 can be swung vertically on the ground surface by the switch of the moving block 27. In an emergency, the chlorine tank 11 can be dropped into the water pool 20 to prevent the occurrence of safety accidents caused by chlorine leakage.
