Description

Technical Field

[0001] The utility model belongs to the technical field of filtration device testing, and particularly relates to a testing device for a filtration device. Background Art

[0002] A filtration device is a device used to filter out certain substances, usually used in the fields of water treatment, air purification, oil pollution treatment, etc. Its main function is to separate waste water, pollutants, particulate matter and other substances from water, air or oil through different filtration mechanisms (such as physical adsorption, chemical adsorption, mechanical filtration, etc.) to achieve the purpose of purifying or separating pure substances. Common filtration devices include filter elements, filter bags, filter meshes, filter plates, etc.

[0003] The main purpose of flushing and testing a filtration device is to evaluate its filtration performance and cleaning effect. The flushing test is usually carried out after a certain period of use to detect whether the filter can maintain its filtration efficiency and resistance after long-term use. The flushing test can be achieved by artificially simulating a water flow or an air flow. In this process, a predetermined detergent or water flow rate and time need to be applied to the filtration device, and then the color, shape and degree of material attenuation of the filter element are checked. If the color and shape of the filter element change, it means that the device has filtered a large amount of substances and needs to be cleaned. If the cleaning effect of the filter is not ideal, it also needs to be maintained and replaced to ensure its normal operation and service life.

[0004] To sum up, it is necessary to conduct a flushing test on the filtration device. The problems existing in the above technology are as follows: There is a lack of a testing device on the current market that can quickly and effectively implement the flushing test, which increases the workload and cost of enterprises during filter maintenance, may also lead to low repair efficiency, and even affect the normal operation of production. Therefore, an efficient, fast and effective testing device is used to conduct a flushing test on the filter to maintain its normal filtration effect, and the filter can be cleaned, maintained and replaced in a timely manner, so as to extend its service life, reduce production costs and improve product quality.

The connection between the fixing plate and the sieve plate provides a support point and controls the rotation of the sieve plate. The supporting block provides further support and controls the opening and closing direction of the sieve plate. At the same time, the connecting rod is linked with the sieve plate to ensure that the sieve plate can move smoothly and quickly. The limiting groove is used to limit the moving direction of the sieve plate and support the position of the fixing block. At the same time, the ring at the upper end of the connecting rod can better connect the connecting rods to ensure the consistency of their operating states.

Finally, the motor is the key component of the whole device, which can provide power transmission to enable the sieve plate to move smoothly and quickly. The construction of the above components can realize an efficient, reliable and fast flushing test device for the filtering device. The function of setting the water tank is to provide continuous water supply, continuously supplement the water source required by the water pump, and ensure the continuity of the test. The water pump is responsible for pumping the water or other liquid in the water tank, transporting it through the pipeline into the communicating plate, and increasing its pressure, while continuously transporting it to the high-pressure nozzle. The high-pressure nozzle can continuously scour the filtering device on the surface of the sieve plate, thereby optimizing the filtering effect. The function of the communicating plate is to evenly distribute the liquid from the water pump into each high-pressure nozzle and keep it transported simultaneously, thereby ensuring the uniformity and integrity of the filtration. The storage pool is used to collect the scoured liquid, prevent the liquid from flowing out of the box body and causing environmental pollution, and can recycle the water resources. Finally, before the liquid flows into the storage pool, the filter plate can filter out the impurities and toxic substances mixed in the used liquid, which can ensure that no adverse impact will be caused to the test and achieve the environmental protection purpose. It solves the problem that there is a lack of testing equipment on the current market that can quickly and effectively implement the flushing test, which increases the workload and cost of enterprises during the maintenance of filters, may also lead to low maintenance efficiency, and even affect the normal operation of production. Therefore, an efficient, fast and effective testing equipment is used to conduct the flushing test on the filter to maintain its normal filtering effect, and the filter can be cleaned, maintained and replaced in time, so as to extend its service life, reduce production costs and improve product quality.

[0025] The working principle of the present utility model:

[0026] During use, before the test starts, first install the filtering device on the surface of the sieve plate 103. Next, operate the control box 11 to start the water pump 203, and convey the liquid in the water tank 204 to the communicating pipe through the pipeline. This process needs to ensure the smoothness of the pipeline to avoid the situation of liquid conveyance obstruction. Then, convey the liquid evenly to the high-pressure nozzle 201 through the communicating pipe. The function of the high-pressure nozzle 201 is to form a uniform water flow on the surface of the sieve plate 103 to wash the filtering device. During the test, the test status can be monitored in real time through the observation window 10. The design of the observation window 10 facilitates observing the liquid flow condition and the changes on the surface of the sieve plate 103, so as to adjust the test conditions in time to achieve the best test effect. When the test reaches the expected result, the motor 109 can be operated through the control box 11. When the motor 109 operates, the front-end driving gear 108 starts to rotate. Due to the meshing relationship between the driving gear 108 and the driven gear 1010, the driven gear 1010 will also rotate accordingly. These two driven gears 1010 are meshed with the rack 107, so that the rack 107 can move up and down during rotation. This design makes the opening and closing of the sieve plate 103 more precise and stable. When the rack 107 moves downward, the positioning rod 102 will also move downward accordingly. The surface of the positioning rod 102 rotates with the two connecting rods 101, so that the fixing block moves along the direction of the limiting groove 105. This design ensures that the moving range of the sieve plate 103 is within the controllable range and ensures the test safety. During the test, the sliding of the fixing block drives the sieve plate 103 to move downward. As the rack 107 continuously falls, the connecting rod 101 moves along the limiting groove 105 to both sides under the drive of the positioning rod 102 until the sieve plate 103 is completely opened. At this time, the filtering device after the test will fall onto the surface of the lower inclined plate 6. To facilitate the removal of the filtering device, the baffle 5 can be opened at this time. In this way, the filtering device can be smoothly removed from the surface of the inclined plate 6 to complete the test process. During the whole test process, the liquid will continuously flow into the storage pool 206 at the bottom of the box body 7. The liquid in the storage pool 206 can be pumped into the water tank 204 through the water pump 203. The filter plate 205 in the water tank 204 processes the liquid to remove the impurities and toxic substances therein. The processed liquid returns to the communicating pipe again to realize the recycling of the liquid and achieve the purpose of saving resources.
