Description

Technical Field

[0001] This utility model relates to the field of sewage discharge accessories, specifically the sewage discharge structure of a nickel carbonate extraction tank. Background Technology

[0002] In the nickel carbonate production process, the nickel carbonate extraction tank is one of the key pieces of equipment, and its operating status directly affects the production efficiency and product quality. The sludge removal operation, as a crucial link in ensuring the stable operation of the nickel carbonate extraction tank, is of paramount importance for maintaining a favorable reaction environment within the tank, preventing impurity accumulation, and extending equipment lifespan. Structurally, existing sludge removal systems for nickel carbonate extraction tanks often lack effective backflushing devices. When the sludge suction pipe becomes blocked, it is difficult to clear the blockage quickly and effectively, forcing the sludge removal operation to be interrupted and affecting production progress. For example, some sludge removal systems rely solely on the suction force of the sludge pump for sludge removal. Once large particles or dirt adhere to the inner wall of the pipe, it easily causes blockage of the suction pipe, which cannot be cleared automatically. Utility Model Content

[0003] The purpose of this invention is to provide a drainage structure for nickel carbonate extraction tanks to solve the problem mentioned in the background art that existing nickel carbonate extraction tanks are prone to clogging during drainage.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The sludge discharge structure of the nickel carbonate extraction tank includes a sludge suction pipe connected to the nickel carbonate extraction tank, a sludge pump installed at one end of the sludge suction pipe, a sludge discharge pipe installed at the outlet end of the sludge pump, a backflushing pipe connected to the outer wall of the sludge suction pipe, and a detachable mesh pipe installed at the end of the sludge suction pipe away from the sludge pump for insertion into the nickel carbonate extraction tank.

[0006] A first control gate valve is installed on the sewage suction pipe, which is located between the backflushing pipe and the sewage pump. A second control gate valve is installed on the backflushing pipe, and a backflushing air pump is installed at the end of the backflushing pipe away from the sewage suction pipe.

[0007] Preferably, a sealing disc is installed at the end of the sludge suction pipe that connects to the nickel carbonate extraction tank, which effectively enhances the sealing of the connection. During the sludge discharge process, it prevents sludge from leaking from the connection point, avoiding pollution of the surrounding environment, while ensuring stable internal pressure of the sludge discharge system, allowing the sludge discharge operation to proceed smoothly.

[0008] Preferably, the sewage pump is equipped with a support base at its bottom, which provides stable support. This helps reduce the vibration and displacement of the sewage pump, ensuring that the sewage pump is always in a normal working position, improving its operational stability and reliability, and extending the service life of the sewage pump.

[0009] Preferably, a check valve is also installed inside the backflushing pipe. The check valve is located between the second control gate valve and the suction pipe. The installation of the check valve inside the backflushing pipe and its proper placement ensure unidirectional flow of the backflushing gas. During backflushing operation, the check valve prevents gas backflow, ensuring that all backflushing gas enters the suction pipe to impact the blocked area, improving the backflushing effect, effectively solving the problem of suction pipe blockage, and ensuring the normal operation of the sewage system.

[0010] Preferably, the mesh tube has several uniformly spaced through holes, which can block large particles of impurities and prevent them from entering the sludge suction pipe and the sludge pump, thus avoiding wear and tear on the equipment caused by large particles of impurities. At the same time, it ensures that the dirt can pass smoothly through the mesh tube into the sludge suction pipe and maintain the normal sludge discharge function of the sludge discharge system.

[0011] Preferably, a threaded connector is installed at one end of the mesh tube that connects to the suction pipe. The threaded connector is threadedly connected to the suction pipe, making the connection more secure and less prone to loosening during sewage discharge. Furthermore, this connection method facilitates disassembly and installation. When the mesh tube needs cleaning or replacement, the operation is simple and quick, reducing equipment maintenance time and improving production efficiency.

[0012] Preferably, the diameter of the mesh tube is smaller than the outer diameter of the suction pipe, allowing the mesh tube to be easily inserted into the suction pipe for convenient installation. Simultaneously, this size design ensures that waste can smoothly enter the suction pipe from the mesh tube, preventing size-related issues from hindering waste flow and ensuring the efficient operation of the sewage system.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the sludge discharge structure of this nickel carbonate extraction tank, a sludge suction pipe is connected to the nickel carbonate extraction tank, and a sludge pump is installed at one end of the sludge suction pipe. The sludge discharge pipe is installed at the outlet end of the sludge pump, which can realize the extraction and discharge of dirt in the nickel carbonate extraction tank. The backflushing pipe connected to the outer wall of the sludge suction pipe, as well as the second control gate valve installed on the backflushing pipe and the backflushing air pump installed at the far end, can backflush the sludge suction pipe when needed. The first control gate valve installed on the sludge suction pipe between the backflushing pipe and the sludge pump can control the opening and closing of the sludge suction pipe. The detachable mesh pipe installed at the end of the sludge suction pipe away from the sludge pump is easy to insert into the inside of the nickel carbonate extraction tank and can filter large particulate impurities. These structures work together to enable the sludge discharge structure to effectively discharge dirt from the nickel carbonate extraction tank and has a backflushing function to prevent the sludge suction pipe from clogging. At the same time, the detachable mesh pipe is easy to clean and maintain. Attached Figure Description

[0026] The sludge removal structure of the nickel carbonate extraction tank, such as Figures 1-3As shown, the system includes a sludge suction pipe 10 connected to a nickel carbonate extraction tank. A sludge pump 20 is installed at one end of the sludge suction pipe 10, and a sludge discharge pipe 30 is installed at the outlet end of the sludge pump 20. A backflushing pipe 50 is connected to the outer wall of the sludge suction pipe 10. A detachable mesh pipe 60 for insertion into the nickel carbonate extraction tank is installed at the end of the sludge suction pipe 10 away from the sludge pump 20. A first control gate valve 40 is installed on the sludge suction pipe 10, located between the backflushing pipe 50 and the sludge pump 20. A second control gate valve 51 is installed on the backflushing pipe 50. A backflushing air pump 53 is installed at the end of the backflushing pipe 50 away from the sludge suction pipe 10. The sludge suction pipe 10 is connected to the nickel carbonate extraction tank, and the sludge pump 20 is installed at one end of the sludge suction pipe 10, with a sludge discharge pipe 30 installed at the outlet end of the sludge pump 20. Pipe 30 allows for the extraction and discharge of sludge from the nickel carbonate extraction tank. A backflushing pipe 50 connected to the outer wall of the suction pipe 10, along with a second control gate valve 51 installed on the backflushing pipe 50 and a backflushing air pump 53 installed at the remote end, allows for backflushing of the suction pipe 10 when necessary. A first control gate valve 40 installed on the suction pipe 10 between the backflushing pipe 50 and the discharge pump 20 controls the opening and closing of the suction pipe 10. A detachable mesh pipe 60 installed at the end of the suction pipe 10 away from the discharge pump 20 facilitates insertion into the nickel carbonate extraction tank and filters large particles. These structures work together to enable the discharge structure to effectively discharge sludge from the nickel carbonate extraction tank, while also providing a backflushing function to prevent blockage of the suction pipe 10. The detachable mesh pipe 60 facilitates cleaning and maintenance.

[0027] Furthermore, a sealing disc 11 is installed at one end of the sludge suction pipe 10 that connects to the nickel carbonate extraction tank, which improves the sealing of the connection between the sludge suction pipe 10 and the nickel carbonate extraction tank and prevents sludge leakage.

[0028] It is worth noting that the bottom of the sewage pump 20 is equipped with a support base 21, which makes the sewage pump 20 more stable during operation and reduces vibration and displacement.

[0029] The backflush pipe 50 is also equipped with a check valve 52, which is located between the second control gate valve 51 and the sewage suction pipe 10, so that the backflush gas can only flow in one direction, preventing backflow and ensuring the backflush effect.

[0030] Specifically, the mesh tube 60 has several evenly spaced through holes 61, which allows the mesh tube 60 to better filter large particles of impurities in the dirt, while ensuring that the dirt can smoothly enter the suction pipe 10.

[0031] In addition, a threaded connector 62 is installed at one end of the mesh tube 60 that connects to the sewage suction pipe 10. The threaded connector 62 is threadedly connected to the sewage suction pipe 10, which makes the connection between the mesh tube 60 and the sewage suction pipe 10 more secure, and facilitates disassembly and installation, cleaning and maintenance.

[0032] It is worth noting that the diameter of the mesh tube 60 is smaller than the outer diameter of the suction tube 10, which allows the mesh tube 60 to be smoothly inserted into the nickel carbonate extraction tank and is easy to install and disassemble.

[0033] The working principle of the sludge discharge structure of this nickel carbonate extraction tank:

[0034] First, open the first control gate valve 40 on the sludge suction pipe 10, while ensuring that the second control gate valve 51 on the backflushing pipe 50 is closed; then, start the sludge pump 20. At this time, the sludge in the nickel carbonate extraction tank will enter the sludge suction pipe 10 through the mesh pipe 60, and then be pressurized by the sludge pump 20 and discharged through the sludge pipe 30 to achieve normal sludge discharge operation.

[0035] If any abnormal situation such as blockage of the suction pipe 10 occurs during the sewage discharge process, first shut down the sewage pump 20 and the first control gate valve 40, then open the second control gate valve 51 and start the backflushing air pump 53. The backflushing gas enters the suction pipe 10 through the backflushing pipe 50 (the check valve 52 in which prevents gas backflow) to backflush the suction pipe 10 and the mesh pipe 60, dispersing the blockage. After the backflushing is completed, shut down the backflushing air pump 53 and the second control gate valve 51, reopen the first control gate valve 40 and start the sewage pump 20 to continue discharging sewage.

[0036] When it is necessary to clean or replace the mesh tube 60, it can be directly disassembled for related operations because it is threadedly connected to the sewage suction pipe 10 through the threaded connector 62. The support base 21 can ensure the stability of the sewage pump 20 throughout the entire usage process.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
