Description

Technical Field

[0001] The utility model relates to the technical field of carbide slag slurry clear liquid conveying systems, and particularly relates to an anti-blocking and anti-air intake device for a carbide slag slurry clear liquid system. Background Technique

[0002] In a wet acetylene gas production device, the general production process of acetylene gas is to measure the raw material calcium carbide with appropriate particle size accurately by weight and then transport it to the wet acetylene gas production device for hydrolysis reaction, so that acetylene gas can be produced for use in the purification process. The by-product of the wet acetylene production device, carbide slag slurry, is sent to a slag slurry clear liquid sedimentation tank for cooling and sedimentation separation treatment. After a period of production use of the slag slurry clear liquid sedimentation tank, two liquid layers, namely a slag slurry clear liquid layer and a thick slurry layer, gradually appear. The upper slag slurry clear liquid is transported to a slag slurry clear liquid conveying system and finally transported to the acetylene gas production device for chemical production use. Since there are often sundries such as plastic blocks, wood blocks, gloves, plastic bags, cooling tower filler blocks, waste cotton yarn, etc. in the slag slurry clear liquid, these sundries will enter the slag slurry clear liquid system together with the slag slurry clear liquid. Then, containing these sundries will cause the flow channel of the carbide slag slurry clear liquid system to be blocked. When the blockage is serious, the equipment has to be stopped for maintenance and cleaning, resulting in unnecessary waste of manpower, material resources and financial resources. This will cause the conveying capacity of the carbide slag slurry clear liquid conveying system to decrease, and may even cause the production capacity of the wet acetylene production device to decline, and the production system safety is not guaranteed, and the process technical index of calcium carbide consumption increases. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides an anti-blocking and anti-air intake device for a carbide slag slurry clear liquid system, which can prevent sundries from entering the carbide slag slurry clear liquid conveying system, and the cleaning of sundries is very convenient.

[0004] To achieve this technical purpose, the utility model adopts the following scheme:

[0005] An anti-blocking and anti-air intake device for a carbide slag slurry clear liquid system includes a central liquid inlet pipe. An anti-blocking filter sleeve is arranged outside the central liquid inlet pipe. A support plate is arranged between the anti-blocking filter sleeve and the central liquid inlet pipe. An upper end plate is fixedly arranged at the top of the anti-blocking filter sleeve, and the upper end plate is fixedly connected to the outer wall of the central liquid inlet pipe. Liquid inlet holes are arranged on both the upper end plate and the upper part of the anti-blocking filter sleeve. A conical head is arranged at the lower end of the anti-blocking filter sleeve.

[0006] Compared with the prior art, the beneficial effect of the utility model lies in:

[0007] The device can prevent sundries such as plastic blocks, wooden blocks, gloves, plastic bags, cooling tower filler blocks, and waste cotton yarn in the clarified liquid of carbide slag slurry from entering the conveying system of the clarified liquid of carbide slag slurry by setting an anti-blocking filter sleeve, and it is very convenient to clean the sundries; by setting a support plate, it is used to realize the passage for the clarified liquid of carbide slag slurry to enter the clarified liquid system of carbide slag slurry. By setting a conical head, when the sundries on the anti-blocking and anti-air-intake device are cleaned up and the anti-blocking and anti-air-intake device is installed and reset, the conical head at the bottom of the device can easily enter the thick slurry layer, and the installation and reset are simple.

[0008] Furthermore, the inside of the conical head is hollow, the liquid inlet of the central liquid inlet pipe is arranged above the conical head, a passage for the clarified liquid of carbide slag slurry is formed between the outside of the central liquid inlet pipe and the conical head, and the clarified liquid of carbide slag slurry enters the central liquid inlet pipe from the liquid inlet to prevent air from entering the clarified liquid system of carbide slag slurry. The conical head is made of carbon steel by machining, and the lower part is firm and wear-resistant.

[0009] Furthermore, the central liquid inlet pipe is connected to the liquid inlet pipe of the clarified liquid system of carbide slag slurry through a flange. Description of the Drawings

[0014] To fully understand the purpose, features and effects of the present invention, the present invention will be described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0015] See Figure 1 and Figure 2, the present utility model provides a technical solution: an anti-blocking and anti-air intake device for a carbide slag slurry supernatant system, including a central liquid inlet pipe 1, and the central liquid inlet pipe 1 is connected to the carbide slag slurry supernatant system liquid inlet pipe 8 through a flange 7. An anti-blocking filter sleeve 2 is arranged outside the central liquid inlet pipe 1, and a support plate 3 is arranged between the anti-blocking filter sleeve 2 and the central liquid inlet pipe 1. The support plates 3 are evenly distributed between the anti-blocking filter sleeve 2 and the central liquid inlet pipe 1 to ensure the overall strength of the device, and a channel for the carbide slag slurry supernatant to enter the carbide slag slurry supernatant system is formed outside the anti-blocking filter sleeve 2. The top of the anti-blocking filter sleeve 2 is fixedly provided with an upper end plate 4, and the upper end plate 4 is fixedly connected to the outer wall of the central liquid inlet pipe 1, preferably by welding. Liquid inlet holes are arranged on both the upper end plate 4 and the upper part of the anti-blocking filter sleeve 2, and the size of the liquid inlet holes is φ30. The lower end of the anti-blocking filter sleeve 2 is provided with a conical head 5, the inside of the conical head 5 is hollow, the liquid inlet 6 of the central liquid inlet pipe 1 is arranged above the conical head 5, and the conical head 5 and the outside of the anti-blocking filter sleeve 2 jointly form a channel for the carbide slag slurry supernatant. The carbide slag slurry supernatant enters the central liquid inlet pipe 1 from the liquid inlet 6. The anti-blocking filter sleeve 2, the upper end plate 4, and the conical head 5 are all made of carbon steel plates with a thickness of 6 mm.

[0016] See Figure 3 , since the slag slurry supernatant sedimentation tank presents two liquid layers, namely a slag slurry supernatant layer and a thick slurry layer, the anti-blocking and anti-air intake device for the carbide slag slurry supernatant system of the present utility model is placed in the sedimentation tank, and the whole device is located below the carbide slag slurry supernatant liquid level, wherein the conical head 5 is located in the thick slurry area, and the elevation of the lower liquid inlet 6 of the central liquid inlet pipe 1 is located above the carbide slag slurry thick slurry area. In this way, it can prevent air from entering the carbide slag slurry supernatant system, and at the same time prevent sundries such as plastic blocks, wooden blocks, gloves, plastic bags, cooling tower filler blocks, and waste cotton yarn from entering the carbide slag slurry supernatant system.

[0017] The carbide slag slurry supernatant enters between the anti-blocking filter sleeve 2 and the central liquid inlet pipe 1 through the liquid inlet holes, enters the central liquid inlet pipe 1 from the liquid inlet 6 at the lower part of the central liquid inlet pipe 1, and then enters the carbide slag slurry supernatant system liquid inlet pipe 8. After running for a period of time, a certain amount of sundries such as plastic blocks, wooden blocks, gloves, plastic bags, cooling tower filler blocks, and waste cotton yarn will accumulate on the outer surface of the anti-blocking filter sleeve 2, resulting in an increase in the flow resistance of the carbide slag slurry supernatant system. At this time, we stop the operation of the carbide slag slurry supernatant system, disassemble the flange 7 between the central liquid inlet pipe 1 of the anti-blocking and anti-air intake device and the carbide slag slurry supernatant system liquid inlet pipe 8, then lift the anti-blocking and anti-air intake device out of the carbide slag slurry supernatant pool, clean the sundries on the outer surface of the anti-blocking filter sleeve 2 and then reinstall it. Due to the structural design of the conical head 5 at the lower end of the anti-blocking and anti-air intake device, the problem of difficult installation and reset of the anti-blocking and anti-air intake device is relatively easily solved.

[0018] Finally, it should be noted that: the above-listed are only the preferred embodiments of the present utility model. Of course, those skilled in the art can make changes and modifications to the present utility model. Provided that these modifications and variations fall within the scope of the claims of the present utility model and its equivalent technologies, they shall be considered as within the protection scope of the present utility model.
