[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-4 As shown, an acetic acid storage tank anti-sedimentation circulation device includes a circulation pipe 1, a filter unit 3, a filter screen 31, a rubber pipe 32, and a threaded pipe 34. The circulation pipe 1 is connected to the acetic acid storage tank. The circulation pipe 1 is a rigid plastic pipe with a safe and harmless anti-corrosion coating for the inside. The circulation pipe 1 is connected to the outside of the acetic acid storage tank through a connecting frame, and both ends of the circulation pipe 1 extend into the inside of the acetic acid storage tank. The circulation pipe 1 and the inside of the acetic acid storage tank are connected for circulation operations.

[0025] To reduce the occurrence of sludge buildup and blockage in the circulation pipe 1, the filter unit 3 is connected to the acetic acid storage tank at the end of the circulation pipe 1. The filter unit 3 includes a filter screen 31, a rubber pipe 32, and a threaded pipe 34. Specifically, the filter screen 31 is placed inside the acetic acid storage tank. The filter screen 31 is a frame with an anti-acetic acid corrosion coating on its periphery and contains a filter mesh inside to reduce the probability of sludge buildup and blockage in the circulation pipe 1. The filter screen 31 is connected to the rubber pipe 32 at the end of the circulation pipe 1. The rubber pipe 32 is a flexible rubber pipe that will be affected by water flow fluctuations during use. Due to the deformable nature of rubber, the water flow will cause the rubber pipe 32 to swing, which in turn causes the filter screen 31 to shake, separating impurities from the surface of the filter screen 31. The end of the rubber pipe 32 away from the filter screen 31 is connected to the threaded pipe 34, which is made of the same material as the circulation pipe 1.

[0026] The filter screen 31 is located on one side of the circulation pipe 1 and is connected to a connecting sleeve 33. The connecting sleeve 33 is used to connect the filter screen 31 and the rubber pipe 32. The threaded pipe 34 is threadedly connected to the circulation pipe 1. The threaded connection between the threaded pipe 34 and the circulation pipe 1 is used to reduce the phenomenon of the rubber pipe 32 falling off when it swings.

[0027] The inside of the connection between the circulation pipe 1 and the threaded pipe 34 is engraved with threads, and the outside of the connection between the threaded pipe 34 and the circulation pipe 1 is engraved with threads.

[0028] Both the threaded pipe 34 and the circulation pipe 1 have circular cross-sections and are used to connect the circulation pipe 1 and the acetic acid storage tank.

[0029] The filter screen 31, connecting sleeve 33, threaded pipe 34 and circulation pipe 1 are connected to each other for circulation operation in the acetic acid storage tank to reduce the precipitation phenomenon in the acetic acid storage tank.

[0030] The overall effect of this embodiment is as follows: First, the circulation pipe 1 is a rigid plastic pipe with a safe and harmless anti-acetic acid corrosion coating inside. The circulation pipe 1 is connected to the outside of the acetic acid storage tank via a connecting frame, and both ends of the circulation pipe 1 extend into the interior of the acetic acid storage tank. The circulation pipe 1 and the acetic acid storage tank are connected for circulation operations. Second, during use, the filter screen 31 is a frame with an anti-acetic acid corrosion coating on its periphery and contains a filter mesh inside to reduce the probability of clogging in the circulation pipe 1. The rubber pipe 32 is designed as a flexible rubber pipe that is subject to water flow fluctuations during use. These fluctuations cause the rubber pipe 32 to swing, which in turn causes the filter screen 31 to shake, separating impurities from the surface of the filter screen 31. The threaded pipe 34 is made of the same material as the circulation pipe 1. The threaded connection between the threaded pipe 34 and the circulation pipe 1 reduces the possibility of the rubber pipe 32 falling off during swinging.

[0031] Example 2

[0032] like Figures 1-4 As shown, an anti-sedimentation circulation device for an acetic acid storage tank is provided. A water pump 2 that controls the flow rate of acetic acid liquid is connected to the circulation pipe 1. The water pump 2 and the circulation pipe 1 are connected and the connection is sealed by existing sealing rings or the like. An outlet 11 is connected to the end of the circulation pipe 1 away from the filter unit 3. The outlet 11 is inserted into the acetic acid storage tank for water discharge. The outlet 11 extends into the acetic acid storage tank to realize circulation operation.

[0033] Both ends of the circulation pipe 1 are connected to flanges 4, which are on a vertical line. The flanges 4 are externally connected to the acetic acid storage tank. The circulation pipe 1 and the acetic acid storage tank are fixed by bolts. At the same time, the part connected by the flanges 4 has an existing sealing structure that is compatible with the equipment for sealing treatment.

[0034] The effect achieved by the entire second embodiment is that, during use, the water pump 2 and the circulation pipe 1 are connected, and the connection is sealed by existing sealing rings, etc., and the outlet 11 is inserted into the acetic acid storage tank for water discharge. The outlet 11 extends into the acetic acid storage tank to realize circulation operation. At the same time, the flange 4 and the external connection of the acetic acid storage tank are fixed by bolts to the circulation pipe 1 and the acetic acid storage tank. The flange connection has an existing sealing structure that conforms to the equipment for sealing treatment.

[0035] Working principle: When using this acetic acid storage tank anti-sedimentation circulation device, an external power supply is used. First, the circulation pipe 1 is a rigid plastic pipe with a safe and harmless anti-acetic acid corrosion coating inside.

Second, when in use, the filter screen 31 is a frame with an anti-acetic acid corrosion coating on the periphery and has a filter screen inside to reduce the probability of sludge accumulation and blockage in the circulation pipe 1. The rubber pipe 32 is designed as a flexible rubber pipe. When in use, it will be affected by water flow fluctuations. After the water flow fluctuations, the rubber pipe 32 will swing, and the rubber pipe 32 will cause the filter screen 31 to shake, separating the impurities on the surface of the filter screen 31 from the filter screen 31. The threaded pipe 34 is made of the same material as the circulation pipe 1. The threaded connection between the threaded pipe 34 and the circulation pipe 1 is used to reduce the phenomenon of the rubber pipe 32 falling off when swinging.

[0036] When in use, the water pump 2 and the circulation pipe 1 are connected, and the connection is sealed with existing sealing rings, etc. The outlet 11 is inserted into the acetic acid storage tank for water discharge. The outlet 11 extends into the acetic acid storage tank to realize circulation. At the same time, the flange 4 is externally connected to the acetic acid storage tank. The circulation pipe 1 and the acetic acid storage tank are fixed with bolts. The flange connection has an existing sealing structure that conforms to the equipment for sealing. Finally, the work of the acetic acid storage tank anti-sedimentation circulation device is completed.
