Description

Technical Field

[0001] This utility model relates to the field of stripping waste liquid storage technology, and in particular to a stripping waste liquid storage tank. Background Technology

[0002] Stripping waste liquid is the waste liquid formed after the stripping fluid is used. Currently, to avoid direct discharge and environmental pollution, it undergoes regeneration treatment, and the regeneration processes used are quite mature. This stripping waste liquid is usually stored in tanks after recycling. With prolonged storage, some substances in the waste liquid adhere to the inner wall of the tank, and some metal ions also precipitate inside. If these substances are not cleaned, long-term use will severely affect the storage capacity and also impact the regeneration yield of the stripping waste liquid. However, the tank is completely sealed, connected to the outside only through pipes, making it inconvenient to clean the inner wall. While manhole covers can be installed on the tank for cleaning, this method suffers from low cleaning efficiency and inconvenience. Utility Model Content

[0003] This utility model provides a stripped waste liquid storage tank to overcome the shortcomings of the prior art and solve the problem of inconvenient cleaning of the storage tank, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A waste liquid stripping storage tank includes a tank body with end rings welded to both ends. Semi-circular shells are located at both ends of the tank body, with fixing rings welded to the inner ends of the semi-circular shells. The fixing rings are fixed to the end rings by multiple bolts. A crossbar is fixed to the semi-circular shell, coaxially arranged with the tank body. A disc is fitted onto the crossbar, and a circular scraper is located on the outer circumference of the disc, its outer circumference closely adhering to the inner wall of the tank body. An inlet pipe and an outlet pipe are connected to the semi-circular shell, the inlet pipe extending upwards and the outlet pipe extending downwards. This design guides the movement of the circular scraper by using the crossbar to prevent tilting during movement. When cleaning the inner wall of the tank, waste liquid can be injected through different inlet pipes, allowing the circular scraper to move under the action of the waste liquid, thus facilitating the cleaning of the inner wall. Furthermore, to prevent leakage of waste liquid between the circular scraper and the tank body during injection, a rubber ring can be installed on the outer wall of the circular scraper.

[0006] Furthermore, a rubber gasket is provided between the fixing ring and the end ring to improve the sealing effect between the fixing ring and the end ring.

[0007] Furthermore, the circular scraper has a wedge-shaped cross-section, which facilitates the removal of deposits from the inner wall of the tank.

[0008] Furthermore, collars are welded to both sides of the disc, and these collars are fitted onto the crossbar, which improves the stability of the disc during movement.

[0009] Furthermore, in order to facilitate fixing the crossbar to the semi-circular shell, an end tube is formed on the semi-circular shell, and screws are formed at both ends of the crossbar. The screws pass through the end tubes, and the outer ends of the screws are connected to a fixing nut by threads. The inner end of the fixing nut is pressed against the outer end of the end tube.

[0010] Furthermore, in order to improve the sealing effect between the two ends of the crossbar and the end tube, an inner rod is provided on the inner side of the screw. The diameter of the inner rod is smaller than that of the crossbar, and the inner rod and the crossbar are connected by a tapered surface. The inner circumference of the end tube is formed with an inner tapered surface, and the tapered surface is tightly attached to the inner tapered surface.

[0011] Furthermore, in order to filter solid impurities during discharge, an outer discharge pipe is bolted to the discharge pipe. A conical filter cover is installed inside the outer discharge pipe. The lower end of the conical filter cover is the smaller end, and multiple leakage holes are opened on the conical filter cover.

[0012] The advantages of the above technical solution are:

[0013] This invention utilizes the pressure generated during waste liquid injection to move a circular scraper, which can clean and scrape the inner wall of the tank during the movement, thus facilitating the cleaning of the inner wall of the tank. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0016] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 .

[0017] Figure 3 A magnified view of point A is shown. Detailed Implementation

[0018] like Figures 1-3 As shown, a stripping waste liquid storage tank includes a tank body 1, with end rings 10 welded to both ends of the tank body 1, and semi-circular shells 2 provided at both ends of the tank body 1. A fixing ring 20 is welded to the inner end of the semi-circular shell 2, and the fixing ring 20 is connected and fixed to the end rings 10 by a plurality of bolts 11. A rubber gasket is provided between the fixing ring 20 and the end rings 10.

[0019] A crossbar 32 is fixed on the semi-circular shell 2. The crossbar 32 is coaxially arranged with the tank body 1. An end tube 25 is formed on the semi-circular shell 2. Screws 3 are formed at both ends of the crossbar 32. The screws 3 pass through the end tube 25, and the outer end of the screws 3 is connected to a fixing nut 30 by a thread. The inner end of the fixing nut 30 is pressed against the outer end of the end tube 25. An inner rod 31 is provided on the inner end of the screw 3. The diameter of the inner rod 31 is smaller than the diameter of the crossbar 32, and the inner rod 31 and the crossbar 32 are connected by a conical surface. An inner conical surface 26 is formed on the inner circumference of the end tube 25. The conical surface is tightly attached to the inner conical surface 26. A disc 40 is sleeved on the crossbar 32. A collar 4 is welded on both sides of the disc 40. The collar 4 is sleeved on the crossbar 32. A circular scraper 41 is provided on the outer circumference of the disc 40. The cross section of the circular scraper 41 is wedge-shaped. The outer circumference of the circular scraper 41 is tightly attached to the inner wall of the tank body 1.

[0020] The semi-circular shell 2 is connected to the feed pipe 21 and the discharge pipe 22. The feed pipe 21 extends upward and the discharge pipe 22 extends downward. The discharge pipe 22 is connected to the discharge outer pipe 23 by bolts. The discharge outer pipe 23 is equipped with a conical filter cover 24. The lower end of the conical filter cover 24 is the small end, and multiple leakage holes are opened on the conical filter cover 24. Valves are installed on both the feed pipe 21 and the discharge pipe 22.

[0021] The solution provided in this embodiment opens a valve on one of the discharge pipes 22 when discharging waste liquid, allowing the waste liquid located between the tank 1 and the disc 40 to be discharged. During discharge, larger solid impurities in the waste liquid are filtered through a conical filter 24. This filtration method allows solid impurities to accumulate at the small end of the conical filter 24, thus avoiding a significant impact on the discharge efficiency of the waste liquid. Furthermore, the conical filter 24 needs to be cleaned regularly.

[0022] In this embodiment, when injecting waste liquid, the valves on each discharge pipe 22 are closed, and then the valve on the inlet pipe 21 near the end of the disc 40 is opened. Subsequently, the waste liquid is injected into the tank 1. During the injection process, as the amount of waste liquid increases, it will push the disc 40 to the other end. During the movement of the disc 40, the circular scraper 41 on it will scrape off the impurities adhering to the inner wall of the tank 1 until the waste liquid injection is completed. Then, the valves on the discharge pipe 22 and the inlet pipe 21 near the end of the disc 40 are opened, and then the semi-circular shell 2 is cleaned by rinsing. During the rinsing process, the residual waste liquid and the leaked waste liquid will be discharged from the discharge pipe 22 and then put into the regeneration system for regeneration.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
