Abstract
Description
Technical Field
[0001] This utility model relates to the field of regenerated stripping fluid production technology, and in particular to a sample filter for regenerated stripping fluid production. Background Technology
[0002] Stripping fluid regeneration refers to restoring used stripping fluid to its original performance through specific treatment methods, making it usable again. During stripping fluid regeneration, the detection of various substances within the fluid is crucial, as the test results are used to develop the subsequent regeneration process. However, the resulting waste stripping fluid typically contains a large amount of solid impurities. These impurities need to be filtered out before production, so compositional analysis is not required. However, the presence of these solid impurities will affect the testing of the waste stripping fluid. Therefore, filtration is necessary before testing. Currently, filtration is mostly done using filter paper, which is slow and requires multiple filtrations, thus affecting testing efficiency. Utility Model Content
[0003] This invention provides a sample filter for the production of regenerated stripping fluid, which overcomes the shortcomings of the prior art and solves the problem of low detection efficiency of waste stripping fluid, and has strong practicality.
[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:
[0005] A sample filter for producing regenerated stripping fluid includes a lower tube body. The lower end of the lower tube body has a conical shell, and the lower end of the conical shell has a lower tube. The lower end of the lower tube has a lower plug. A filter cover is threadedly connected to the upper end of the lower tube body. Multiple holes are formed at the bottom of the filter cover, and a filter membrane is located at the bottom of the filter cover. When waste stripping fluid passes through the filter membrane, solid impurities are filtered out. The resulting filtrate can be discharged through the lower tube or stored in the lower tube body. For ease of operation, several small holes are also formed at the upper end of the lower tube body. An upper tube is threadedly connected to the upper end of the lower tube body. An end plate is located at the upper end of the upper tube. A screw is threadedly connected to the center of the end plate. A squeezing plate is rotatably mounted at the lower end of the screw, located inside the upper tube. An end cap is located at the upper end of the screw. The movement of the squeezing plate allows for rapid extrusion of the waste stripping fluid. Increasing the flow rate improves filtration efficiency, and the screw-driven mechanism reduces the difficulty of establishing pressure within the squeezing plate.
[0006] The lower end of the upper tube is threadedly connected to an inner connecting ring. The upper end of the inner connecting ring has a conical hopper, with a smaller lower end. A lower extension ring is located at the lower end of the conical hopper, and a sealing inner ring is threadedly connected inside the lower extension ring. The inner circumference of the lower end of the sealing inner ring is conical, with the upper end of the conical structure being smaller. A movable tube passes through the sealing inner ring. The upper outer circumference of the movable tube has a raised edge, and a spring is fitted onto the upper end of the movable tube, located between the raised edge and the sealing inner ring. The lower outer circumference of the movable tube also has a conical structure. The upper end of the structure is small, and the conical structure on the movable tube is tightly attached to the conical structure of the sealing inner ring. The conical structure on the outer periphery of the lower end of the movable tube has multiple liquid outlet holes. The lower end of the movable tube is connected to an end cap by a thread. When filtering, the waste stripping liquid will pass through the movable tube. When squeezed, the movable tube will move downward, thereby removing the sealing inner ring from the liquid outlet holes, allowing the waste stripping liquid to be discharged from the inside out. The distribution of the liquid outlet holes can prevent solid impurities from accumulating at a single location on the filter membrane, thus affecting the filtration effect.
[0007] Furthermore, in order to increase the filtration area during filtration, a protrusion is formed at the bottom of the filter cover.
[0008] Furthermore, in order to avoid solid impurities accumulating on the filter membrane and to facilitate the cleaning of solid impurities, the protrusion has a conical structure, and the upper end of the protrusion is the smaller end.
[0009] Furthermore, to facilitate the disassembly and cleaning of the filter cover, multiple fins are provided on the inner circumference of the filter cover.
[0010] Furthermore, in order to improve the stability of the filter cover after installation, a limiting ring is provided at the upper end of the lower tube body, and the filter cover is located above the limiting ring.
[0011] Furthermore, in order to improve the sealing effect of the lower plug and prevent leakage, a limiting end ring is provided on the outer periphery of the lower tube. The lower plug is connected to the outer periphery of the lower tube by threads and is located below the limiting end ring. A plug is provided inside the lower plug and the plug passes through the lower tube.
[0012] Furthermore, to facilitate the disassembly and installation of the inner connecting ring, multiple inner protrusions are provided at the lower end of the inner circumference of the inner connecting ring.
[0013] Furthermore, in order to facilitate the entry of waste stripping fluid, a first conical hole is formed at the upper end of the movable tube. The upper end of the first conical hole is the large end, and the lower end of the first conical hole is connected to the liquid outlet chamber. The liquid outlet hole is connected to the liquid outlet chamber, and the end cap is located at the lower end of the liquid outlet chamber.
[0014] Furthermore, in order to facilitate the connection operation between the upper and lower tubes, a holding ring is provided on the outer periphery of the lower end of the upper tube, and an end grip ring is provided on the outer periphery of the upper end of the lower tube.
[0015] The advantages of the above technical solution are:
[0016] This invention can improve the filtration efficiency and filtration effect of waste stripping fluid. Attached Figure Description

[0025] The lower tube 13 is provided with a limiting end ring 14 on its outer periphery. The lower plug 2 is connected to the outer periphery of the lower tube 13 by a thread, and the lower plug 2 is located below the limiting end ring 14. The lower plug 2 is provided with a plug 20 inside, and the plug 20 passes through the lower tube 13.
[0026] The upper end of the lower tube 1 is connected to the upper tube 4 by a thread. The upper end of the upper tube 4 is provided with an end plate 41. The center of the end plate 41 is connected to a lead screw 42 by a thread. The lower end of the lead screw 42 is provided with a pressing plate 44, which is located inside the upper tube 4. The upper end of the lead screw 42 is provided with an end cap 43.
[0027] The lower end of the upper tube 4 is threadedly connected to an inner connecting ring 45. The lower end of the inner circumference of the inner connecting ring 45 has multiple inner protrusions 46. The upper end of the inner connecting ring 45 has a conical hopper 5, with the lower end of the conical hopper 5 being the smaller end. The lower end of the conical hopper 5 has a lower extension ring 50, and a sealing inner ring 51 is threadedly connected inside the lower extension ring 50. The lower inner circumference of the sealing inner ring 51 has a conical structure, with the upper end of the conical structure of the sealing inner ring 51 being the smaller end. A movable tube 52 passes through the sealing inner ring 51. The outer circumference of the upper end of the movable tube 52 has a raised edge 53. A spring is fitted onto the upper end of the movable tube 52, and the spring is located between the raised edge 53 and... Between the sealing inner ring 51, the lower outer periphery of the movable tube 52 has a conical structure, and the upper end of the conical structure on the lower outer periphery of the movable tube 52 is the small end. The conical structure on the movable tube 52 is in close contact with the conical structure of the sealing inner ring 51. Multiple liquid outlet holes 56 are provided on the conical structure on the lower outer periphery of the movable tube 52.
