Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a two-pass coarse filtration structure of a filter chamber. Background Art

[0002] The current two-pass coarse filtration structure of the filter chamber usually refers to the two preliminary filtration stages set in the filtration process to remove larger impurities and particulate matter. This structure is widely used in various filtration systems, including water treatment, air purification, oil filtration and other fields.

[0003] In the Chinese utility model patent with announcement number CN217854779U, a waste mineral oil filtering device is disclosed. Although the above-mentioned prior art can automatically and quickly clean the stains on the inner wall of the oil storage tank and can conveniently replace the filter screen, the filtration is divided into multiple steps, namely, the first filtration and the second filtration. The second filtration is to filter out slightly larger particles again on the basis of the first filtration. The slightly larger particles will block the filter holes of the filter screen due to the drop of gravity during filtration, which reduces the filtration efficiency. At this time, the filter screen needs to be taken out and cleaned to restore the previous filtration speed. However, the filter screen is generally fixed inside the filter chamber, and it is very time-consuming to take it out for cleaning. Therefore, the staff generally waits until the filtration is completed before cleaning it. If it is not cleaned, the filtration speed will be affected. Therefore, it is necessary to design a filter structure that can be quickly taken out and cleaned. Utility Model Content

[0004] In order to solve the technical problem that the filter screen is inconvenient to be taken out from the filter chamber for cleaning, resulting in reduced filtration efficiency, the utility model provides a two-pass coarse filtration structure for the filter chamber.

[0005] The utility model is implemented by the following technical solutions: a filter chamber two-pass coarse filtration structure, including a filter cartridge, a filter screen for two-pass coarse filtration is provided inside the filter cartridge, a closing component is provided on one side of the filter cartridge that allows the filter screen to be quickly removed from the filter cartridge, a vibration component is provided on the bottom of the filter screen that allows the filter screen to shake during filtration to improve the filtration effect, a mounting port is provided on one side of the filter cartridge, the closing component includes a closing plate arranged on the mounting port and a sealing ring fixedly sleeved on the closing plate, and the sealing ring is adapted to the mounting port.

[0006] Through the above technical solution, when the filter needs to be cleaned, you only need to open the closing component to directly take out the filter, and the vibration component will make the filter vibrate, thereby reducing the possibility of the filter holes being blocked and extending the filtering time of each filter. This setting can perform a second coarse filtration without worrying about the filter holes being blocked, and the filter can be quickly taken out for cleaning.

[0007] As a further improvement of the above solution, the closing plate is arranged in an arc shape, and the closing plate is adapted to the installation opening.

[0008] Through the above technical solution, the closing plate cooperates with the sealing ring to block and seal the installation port to prevent leakage during the filtration process.

[0009] As a further improvement of the above solution, a limiting ring fixedly mounted on the inner wall of the filter cartridge is provided at the bottom of the filter screen, and a limiting ring slidingly engaged with the inner wall of the filter cartridge is fixedly mounted on the top of the filter screen.

[0010] Through the above technical solution, the limiting ring can prevent the filter from falling, and the limiting ring can limit the filter when it moves up and down to prevent the filter from tilting.

[0011] As a further improvement of the above solution, the sliding sleeve on the outer surface of the filter cartridge is provided with a sealing ring, the fixed sleeve on the outer surface of the sealing ring is provided with a fixing ring, a baffle is fixedly installed on one side of the filter cartridge, and a fixing groove adapted to the fixing ring is opened on one side of the baffle.

[0012] Through the above technical solution, the sealing ring and the fixing ring will limit and seal the position of the closing plate to prevent the closing plate from loosening.

[0013] As a further improvement of the above solution, the vibration assembly includes a servo motor arranged at the bottom of the filter screen, a rotating rod fixedly installed on the output end of the servo motor, and an eccentric plate fixedly sleeved on the rotating rod.

[0014] Through the above technical solution, when the servo motor is started, the rotating rod will rotate, thereby allowing the eccentric plate to push the filter screen.

[0015] As a further improvement of the above solution, the outer sleeve of the servo motor is provided with a protective box fixedly mounted on the inner wall of the filter cartridge, one end of the rotating rod is rotatably mounted with a fixed block fixedly mounted on the inner wall of the filter cartridge, and the protective box rotates in conjunction with the rotating rod.

[0016] Through the above technical solution, the protection box can protect the servo motor and prevent water from contacting the servo motor.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a closing component and a vibration component. When the filter holes of the filter screen are blocked by the filter material and the filter screen needs to be cleaned, the closing component only needs to be opened to directly take out the filter screen for quick cleaning. The vibration component will vibrate the filter screen, thereby reducing the possibility of the filter holes being blocked and extending the filtering time of each filter screen. This arrangement can perform a second coarse filtration without worrying about the filter holes being blocked, and the filter screen can be quickly taken out for cleaning and quickly installed after cleaning.

[0025] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figures 1-4The filter screen 2 of this embodiment is to be filtered out, and filter screen 2 is to be taken out from filter cartridge 1.

[0027] Combine Figure 1-Figure 3 The bottom of the filter screen 2 is provided with a limiting ring 5 fixedly mounted on the inner wall of the filter cylinder 1, and the top of the filter screen 2 is fixedly mounted with a limiting ring 6 that slides with the inner wall of the filter cylinder 1. The sliding sleeve of the outer surface of the filter cylinder 1 is provided with a sealing ring 7, and the outer surface of the sealing ring 7 is fixedly sleeved with a fixing ring 8. A baffle 9 is fixedly mounted on one side of the filter cylinder 1, and a fixing groove adapted to the fixing ring 8 is opened on one side of the baffle 9. The limiting ring 5 will prevent the filter screen 2 from falling, and the limiting ring 6 will limit the position of the filter screen 2 when it moves up and down to prevent the filter screen 2 from tilting. The sealing ring 7 and the fixing ring 8 will limit and seal the position of the closing plate 301 to prevent the closing plate 301 from loosening.

[0028] Combine Figure 2 and Figure 4 The vibration assembly includes a servo motor 401 arranged at the bottom of the filter 2, a rotating rod 402 fixedly mounted on the output end of the servo motor 401, and an eccentric plate 403 fixedly sleeved on the rotating rod 402. The outer sleeve of the servo motor 401 is provided with a protective box 10 fixedly mounted on the inner wall of the filter cartridge 1. One end of the rotating rod 402 is rotatably mounted with a fixed block fixedly mounted on the inner wall of the filter cartridge 1. The protective box 10 rotates in coordination with the rotating rod 402. When the servo motor 401 is started, the rotating rod 402 will rotate, thereby allowing the eccentric plate 403 to push the filter 2.

[0029] When the filter screen 2 is cleaned, the sealing ring 7 can be moved upwards to expose the sealing plate 301, so that the sealing plate 301 can be opened and the filter screen 2 can be taken out for cleaning. After the filter screen 2 is cleaned, it can be quickly placed in the filter cartridge 1, and then the sealing plate 301 can be matched with the sealing ring 302 to block the filter cartridge 1. In this way, the filter screen 2 can be quickly cleaned and installed and fixed, saving filtering time. After the servo motor 401 is started, the rotating rod 402 will drive the eccentric plate 403 to rotate. In this way, under the impact of the eccentric plate 403, the filter screen 2 will vibrate, thereby causing the impurity particles to shake and reducing the possibility of the filter holes being blocked. This setting can extend the filtering time of the filter screen 2 and improve the filtering efficiency.

[0030] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
