Description

Technical fields:

[0001] This utility model relates to the field of recycling technology, specifically to an auxiliary device for preventing overflow when filling barrels with waste catalysts. Background technology:

[0002] The BYD reactor is a key piece of equipment for the production of 1,4-butanediol (BDO). During operation, the catalyst needs to be replaced regularly. The replaced spent catalyst is in the form of sludge, with a certain viscosity and adhesion. Because the spent catalyst contains residual formaldehyde, it is highly irritating to the eyes and respiratory tract of workers, causing damage to their occupational health.

[0003] Therefore, the replaced waste catalyst is first discharged into a collection pool, and then an excavator is used to dig out the waste catalyst from the collection pool and put it into a collection bucket, which is then transported to the treatment center for centralized processing.

[0004] The current problem is that during the process of the excavator unloading into the collection bucket, because the excavator bucket is square and the collection bucket has a round opening, the waste catalyst is very easy to spill outside the bucket during loading and unloading, causing ground pollution. It is necessary to use shovels to work with the excavator to level the bucket. After leveling one bucket, the above operation is repeated before the next bucket is filled. This results in multiple close contacts between the workers and the waste catalyst, which has an impact on the workers' health. Utility Model Content:

[0005] The purpose of this invention is to provide an auxiliary device for preventing overflow when filling waste catalyst drums, so as to solve the problems mentioned in the background art.

[0006] This utility model is implemented by the following technical solution:

[0007] An auxiliary device for preventing overflow during waste catalyst loading includes a buffer tank, support legs, a discharge steel pipe, a support frame, cylinders, an insert plate, a support plate, and manual valves. The buffer tank is fixed with support legs around its perimeter. Two discharge steel pipes, communicating with the buffer tank, are symmetrically fixed to the bottom of the buffer tank. A support frame is detachably installed at the bottom of the buffer tank and is horizontally positioned. Two cylinders are fixed on the support frame. One end of the piston rod of each cylinder is threadedly connected to one end of the insert plate. The discharge steel pipe has a slot adapted to the insert plate, allowing the insert plate to be inserted into the slot, thus opening or closing the discharge steel pipe. A support plate is fixed to the buffer tank, and two manual valves are fixed to the support plate. The inlet of each manual valve is connected to an air source via an air pipe, and the two outlets of each manual valve are connected to the two inlets of the cylinders via air pipes.

[0008] Preferably, the support frame includes four channel steels and square steel. The structure of the support frame is in the shape of "曰". The four channel steels are fixedly connected to form a "口" shape, and the openings of the channel steels face outward. The square steel is fixed between two symmetric channel steels. The support frame is fixed with three connecting rods. The top ends of the connecting rods and the edges of the lower surface of the top of the buffer box are fixedly connected by bolts. The lower surface of the buffer box is fixed with angle steel. One of the channel steels connected to the square steel is lapped on the angle steel.

[0009] Preferably, the outer diameter of the blanking steel pipe is smaller than the diameter of the feed inlet of the collection barrel.

[0010] Advantages of the present utility model: During the entire unloading process, it avoids the phenomenon of overflow when loading waste catalysts into the barrel, reduces the labor intensity of personnel, avoids the risk of direct contact between personnel and hazardous substances caused by manual cooperation in loading and transportation, and improves the loading and transportation efficiency of BYD waste catalysts.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-7 , the present utility model provides a technical solution for an anti-overflow auxiliary device for filling waste catalysts into barrels:

[0021] An anti-overflow auxiliary device for filling waste catalysts into barrels includes a buffer tank 1, support legs 2, a feeding steel pipe 3, a support frame 4, a cylinder 5, a plug plate 6, a support plate 7, and a manual valve 8;

[0022] Support legs 2 are fixed around the buffer tank 1, and two feeding steel pipes 3 communicating with the buffer tank 1 are symmetrically fixed at the bottom of the buffer tank 1. The outer diameter of the feeding steel pipe 3 is smaller than the diameter of the feeding port of the collection barrel.

[0023] The support frame 4 includes four channel steels 4.1 and square steels 4.2. The structure of the support frame 4 is in the shape of "曰". The four channel steels 4.1 are fixedly connected to form a "口" shape, and the grooves of the channel steels 4.1 face outward. The square steel 4.2 is fixed between two symmetric channel steels 4.1. For the convenience of subsequent equipment maintenance and to be able to quickly disassemble the support frame 4 from the buffer tank 1, three connecting rods 9 are fixed to the support frame 4. The top ends of the connecting rods 9 and the edge of the lower surface of the top of the buffer tank 1 are fixedly connected by bolts. An angle steel 10 is fixed on the lower surface of the buffer tank 1. One of the channel steels 4.1 connected to the square steel 4.2 is lapped on the angle steel 10, so that the support frame 4 is horizontally arranged.

[0024] Two cylinders 5 are fixed to the support frame 4. One end of the piston rod of the cylinder 5 is threadedly connected and fixed to one end of the plug plate 6. A slot 3.1 adapted to the plug plate 6 is opened on the feeding steel pipe 3, so that the plug plate 6 is movably inserted into the slot 3.1 to open or close the feeding steel pipe 3.

[0025] In order to enable the plug plate 6 to move and penetrate in the slot 3.1, a support plate 7 is fixed to the buffer tank 1. Two manual valves 8 are fixed to the support plate 7. The air inlet ends of the manual valves 8 are connected to the air source through air pipes, and the two air outlet ends of the manual valves 8 are respectively connected to the two air inlet ends of the cylinders 5 through air pipes. By controlling the rotation of the manual valve 8, the piston rod of the cylinder 5 is extended or retracted.

[0026] The model of this manual valve is VH / HV series pneumatic switch hand-turn valve.

[0027] The working principle is as follows: The collection bucket to be loaded is placed under the two discharge steel pipes 3. The excavator pours the excavated waste catalyst into the buffer box 1. Then, the manual valve 8 is controlled to retract the piston rod of the cylinder 5. The insert plate 6 slides out from the slot 3.1 to open the discharge steel pipe 3. The waste catalyst falls into the collection bucket through the discharge steel pipe 3 for collection. When the collection bucket is full, the manual valve 8 is controlled to extend the piston rod of the cylinder 5. The insert plate 6 is inserted into the slot 3.1 to close the discharge steel pipe 3. Then, the collection bucket is replaced and the above operation is repeated.

[0028] Throughout the unloading process, the overflow of waste catalysts during loading into drums was avoided, reducing the labor intensity of personnel, avoiding the risk of personnel directly contacting hazardous materials due to the need for manual assistance in loading and transportation, and improving the loading and transportation efficiency of BYD waste catalysts.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
