Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory waste liquid treatment technology, and in particular to a laboratory waste liquid discharge device with a filter anti-clogging structure. Background Technology
[0002] Medical testing technology refers to the use of various instruments, equipment, reagents, and techniques to detect and analyze human samples such as blood, body fluids, secretions, excretions, and tissue cells, thereby providing objective evidence for the diagnosis, treatment, monitoring, and prevention of diseases. In the field of medical testing, a waste liquid discharge device with a filter and anti-clogging structure is used to treat various waste liquids generated during medical testing. This device aims to separate and treat solid impurities, harmful microorganisms, and chemical substances in medical testing waste liquids through filtration and other methods, preventing these substances from clogging the discharge pipes, reducing the risk of environmental pollution, and ensuring that the waste liquid can be discharged safely and smoothly.
[0003] However, existing waste liquid discharge devices with filter anti-clogging structures have the following disadvantages:
[0004] (1) The waste liquid usually contains various solid impurities. If the discharge device is difficult to filter, these impurities may directly enter the discharge pipe. Over time, the impurities will accumulate in the pipe, causing the inner diameter of the pipe to become smaller, eventually leading to blockage and affecting the normal discharge of the waste liquid.
[0005] (2) If it is difficult to disassemble the filter screen, the filter screen may cause the flow resistance of the waste liquid in the discharge device to increase after a period of use, which will affect the discharge efficiency of the waste liquid. In severe cases, it may cause the waste liquid to flow back, thereby affecting the normal operation of the inspection work.
[0006] Therefore, this utility model provides a waste liquid discharge device with a filter and anti-clogging structure. Utility Model Content

[0018] (III) Beneficial Effects
[0019] This utility model provides a waste liquid discharge device with a filter and anti-clogging structure, which has the following advantages:
[0020] 1. This wastewater discharge device with a filter and anti-clogging structure, through the arrangement of a storage tank, connecting plate, first filter screen, second filter screen, and third filter screen, allows for the filtration of wastewater. First, the wastewater enters the filter tank through the feed hopper, then contacts the first filter screen. The larger pore size of the first filter screen initially intercepts larger particles in the wastewater. The smaller pore size of the second filter screen further filters out slightly smaller particles. Finally, the smallest pore size of the third filter screen intercepts even finer particles and colloidal substances, thus filtering out solid impurities in the wastewater. This significantly improves the purity of the filtered wastewater, ensuring it meets higher standards, reducing the load on subsequent wastewater treatment systems, and lowering the risk of environmental pollution.
[0021] 2. This waste liquid discharge device with a filter and anti-clogging structure, through the setting of a limiting plate, threaded rod and handle, allows for easy removal of the filter screen when it is necessary to disassemble it. First, the user holds the handle and rotates it counterclockwise. Then, the handle drives the threaded rod to rotate in the threaded hole and disengage from its constraint. After the threaded rod is completely disengaged from the threaded hole, the user holds the limiting plate with both hands and pulls the filter screen upwards steadily and slowly. This completes the disassembly of the filter screen, facilitating the timely removal of trapped impurities and effectively preventing excessive accumulation of impurities from affecting the filtration effect, thus ensuring the continuous and efficient operation of the waste liquid filtration discharge system.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a waste liquid discharge device for testing with a filter and anti-clogging structure, including a storage tank 1 and a disassembly assembly 3. The storage tank 1 is internally equipped with a filter assembly 2, which includes a filter groove formed inside the storage tank 1. Multiple connecting plates 201 are slidably connected to the inner wall of the filter groove. A first filter screen 202 is fixedly connected to the upper end of one side of each connecting plate 201, a second filter screen 203 is fixedly connected to the middle end of one side of each connecting plate 201, and a third filter screen 203 is fixedly connected to the lower end of one side of each connecting plate 201. The pore sizes of filter screens 204, 202, 203, and 204 decrease sequentially. Through the arrangement of storage tank 1, connecting plate 201, and the first, second, and third filter screens 202, when waste liquid needs to be filtered, the waste liquid first enters the filter tank through the feed hopper 5, then comes into contact with the first filter screen 202. The larger pore size of the first filter screen 202 can initially intercept larger impurities in the waste liquid. Then, the smaller pore size of the second filter screen 203 further filters out the waste liquid. Smaller particles are filtered out by the third filter 204, which has the smallest pore size, thus intercepting even finer particles and colloidal substances in the waste liquid. The disassembly assembly 3 includes a limiting groove inside the storage tank 1. Multiple threaded holes are formed on the surface of the limiting groove. A limiting plate 301 is fixedly connected to the top of the connecting plate 201, and the limiting plate 301 is adapted to the limiting groove. A rotating groove is formed at the center of the limiting plate 301, and a threaded rod 302 is rotatably connected to the inner wall of the rotating groove. One side of the threaded rod 302... The end is fixedly connected with a handle 303, and the threaded rod 302 is adapted to the threaded hole and the rotating groove. With the setting of the limiting plate 301, the threaded rod 302 and the handle 303, when the filter screen needs to be disassembled, the user first holds the handle 303 and rotates it counterclockwise. Then the handle 303 drives the threaded rod 302 to rotate in the threaded hole and get out of its restriction. After the threaded rod 302 is completely out of the restriction of the threaded hole, the user holds the limiting plate 301 with both hands and lifts the filter screen upward steadily and slowly. This completes the disassembly of the filter screen.
[0029] A lid 4 is fixedly connected to the top of the storage tank 1. The lid 4 facilitates the sealing and protection of the storage tank 1. There is one lid 4.
[0030] The top of the tank cover 4 is provided with a feed hopper 5. The feed hopper 5 facilitates the flow of waste liquid. One end of the feed hopper 5 extends into the interior of the storage tank 1.
[0031] The bottom of the storage tank 1 is fixedly connected to a support leg 6. The support leg 6 provides effective and stable support for the storage tank 1. The bottom of the support leg 6 is fixedly connected to a support block.
[0032] The bottom of the storage tank 1 is provided with a discharge hopper 7, which facilitates the discharge of filtered waste liquid. One end of the discharge hopper 7 extends into the interior of the storage tank 1.
[0033] Two handles 8 are fixedly connected to the surface of the storage tank 1. The handles 8 facilitate the movement of the device by the user. The two handles 8 are arranged symmetrically.
[0034] In this invention, the working steps of the device are as follows:
[0035] First step: First, the waste liquid enters the filter tank through the feed hopper, and then comes into contact with the first filter screen. The larger pore size of the first filter screen can initially intercept larger impurities in the waste liquid. Then, the smaller pore size of the second filter screen can further filter out slightly smaller impurities in the waste liquid. Finally, because the pore size of the third filter screen is the smallest, it can intercept even finer particles and colloidal substances in the waste liquid, thereby filtering out solid impurities in the waste liquid.
[0036] Step 2: The user holds the handle 303 and rotates it counterclockwise. Then the handle 303 drives the threaded rod 302 to rotate in the threaded hole and disengage from its restriction. After the threaded rod 302 is completely disengaged from the threaded hole, the user holds the limiting plate 301 with both hands and slowly and steadily pulls the filter screen upwards. This completes the disassembly of the filter screen.
