Description

Technical Field

[0001] The invention relates to the technical field of caustic soda flake production, and in particular to a feeding device for caustic soda flake production and a use method thereof. Background Art

[0002] In the production process of caustic soda flakes, a feeding device is usually needed to transport the caustic soda flakes from the previous process to the next process. The feeding device plays a vital role in the production of caustic soda flakes. Some existing caustic soda flake feeding devices use caustic soda flake chain conveyors. The caustic soda flake chain conveyor is a continuous conveying equipment specially used for conveying bulk materials such as powder, small particles and small blocks. It uses chains or discs as transmission components to drive the material along the pipeline in a closed pipeline, thereby realizing the transportation of materials. When working, the gears rotate the pipe chain, and then the discs on the pipe chain drive the material to complete the entire conveying process.

[0003] In the long-term transportation process of some existing flake caustic soda tube chain conveyors, the tube chain is easy to loosen. When the tube chain is in a relaxed state, when a joint in the tube chain is about to contact a gear in the sprocket, it is easy for the gear on the sprocket to fail to accurately penetrate into the corresponding joint hole, causing the entire tube chain to be disconnected from the sprocket. Since there is no corresponding tube chain tensioning mechanism, the tube chain cannot be tensioned and adjusted after it is relaxed. With the development of technology, some flake caustic soda tube chain conveyors are equipped with corresponding tensioning mechanisms to adjust the tension of the tube chain, but most of the tensioning mechanisms are manually adjusted, and the adjustment process is cumbersome and inefficient.

[0004] After the flake caustic soda tube chain conveyor is finished feeding, the disc in the feeding tube will be attached with residual caustic soda. If it is not cleaned in time, it is easy to cause pollution to the subsequent flake caustic soda transportation. However, some existing flake caustic soda tube chain conveyors do not have a cleaning mechanism, which makes it impossible to clean the disc after the flake caustic soda tube chain conveyor is finished feeding, which is easy to affect the quality of the subsequent feeding. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a feeding device for flake caustic soda production, which solves the problem that the tube chain of some flake caustic soda tube chain conveyors is easy to loosen during the long-term conveying process.

Since there is no corresponding tube chain tensioning mechanism, the tube chain cannot be tensioned and adjusted after relaxation, and most of the tensioning mechanisms are manually adjusted, and the adjustment process is cumbersome and inefficient. In addition, some flake caustic soda tube chain conveyors do not have a cleaning mechanism, which makes it impossible for the flake caustic soda tube chain conveyors to perform corresponding cleaning of the disc after feeding is completed, which may easily affect the later feeding quality.

A feeding device for producing caustic soda flakes according to claim 8, characterized in that: The driving assembly (42) comprises a third motor (421), a first transmission wheel (422), a first transmission belt (423), a second transmission wheel (424), a second transmission belt (425) and a rotating rod (426); the third motor (421) is arranged above the cleaning box (41); a plurality of first transmission wheels (422) are arranged, and the plurality of first transmission wheels (422) are transmission-connected to the first transmission belt (423); one of the first transmission wheels (422) is connected to the output end of the third motor (421); the second transmission wheel (424) is arranged on one side of the brush roller (43), and the second transmission wheel (424) and the first transmission wheel (422) are transmission-connected via the second transmission belt (425); the rotating rod (426) is fixedly inserted into the brush roller (43), and one end of the rotating rod (426) is fixedly sleeved on the second transmission wheel (424).

10. The method for using the feeding device for producing flake caustic soda according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: Step 1: First, the starting assembly (12) is turned on, and the starting assembly (12) starts to drive the tube chain (33) to move in the feeding tube (31); Step 2: The tube chain (33) moves, driving the disc (34) on the tube chain (33) to move in the feeding tube (31), and the flake caustic soda enters the feeding tube (31) and falls between the two discs (34), and is transported along with the movement of the tube chain (33); Step 3: After the caustic soda flakes are discharged, the disc (34) passes through the driven component (22) and enters the conveying pipe (32). After being transferred through the conveying pipe (32), it passes through the starting component (12) and enters the feeding pipe (31) for caustic soda flake transmission; Step 4: Starting the rotating component (24) can drive the moving component (23) to operate, thereby driving the driven component (22) to move, thereby completing the tensioning of the pipe chain (33).
