Description

Technical Field

[0001] This application relates to the technical field of basket filters, and specifically to a new type of basket filter. Background Art

[0002] A basket filter is used on oil or other liquid pipelines to filter debris in the pipeline. The filtering hole area is 2 - 3 times larger than the area of the through - diameter pipe, far exceeding the filtering areas of Y - type and T - type filters. The filter precision of the basket filter belongs to one of the best in filters. The filter screen structure is different from other filter screens. Because of its shape like a basket, it is named basket filter.

[0003] The existing patent (publication number: CN 218686897 U) discloses a new type of basket filter, belonging to the technical field of basket filters, including a filter cylinder and a filter screen. The filter screen is supported inside the filter cylinder, and an opening is provided at the bottom end of the filter screen. It also includes: a feed port provided at the bottom end of the circumferential side of the filter cylinder; a discharge port provided at the upper end of the circumferential side of the filter cylinder; a sewage discharge port provided at the bottom end of the filter cylinder, and a sewage discharge valve is provided in the sewage discharge port. The utility model filters in the way of entering from the bottom and discharging from the top. The filtered impurities remain at the bottom of the filter cylinder. After the impurities accumulate to a certain extent, the sewage discharge valve is opened to discharge the impurities, and there is no need to open the cover to remove the filter basket for cleaning the filter screen; it solves the problem that the existing basket filter must take out the filter basket for cleaning after filtering for a period of time, which is rather troublesome to disassemble and assemble during use and has low efficiency.

[0004] The filter screen of the above - mentioned filter still has the possibility of being blocked by impurities during operation. Once the filter screen is blocked, it will affect the filtering operation efficiency, and the impurities may accumulate at the bottom of the filter during the discharge process, causing the blockage of the sewage discharge port and affecting the normal sewage discharge operation. Summary of the Utility Model

Once the filter screen is blocked, it will affect the filtering operation efficiency, and the impurities may accumulate at the bottom of the filter during the discharge process, causing the blockage of the sewage discharge port and affecting the normal sewage discharge operation.

[0006] To achieve the above object, the present application provides the following technical solution: a novel basket filter, including a cylinder body, wherein a support ring is fixedly connected to the inner wall of the cylinder body, a filter screen is arranged on the upper surface of the support ring, a feed port is arranged inside the cylinder body, a discharge port is arranged inside the cylinder body, an upper cover is slidably sleeved on the top end of the cylinder body, a sewage discharge port is arranged at the bottom of the cylinder body, a lower cover is threadedly connected to the outer circumferential surface of the sewage discharge port, a fixed seat is fixedly connected to the inner wall of the cylinder body, a rotating shaft is rotatably inserted into the inside of the fixed seat, a scraping plate is fixedly sleeved on the outer circumferential surface of the rotating shaft, the upper surface of the scraping plate is in contact with the bottom surface of the filter screen, equally spaced stirring rods are fixedly connected to the outer circumferential surface of the rotating shaft, a cleaning plate is fixedly connected to the outer circumferential surface of the rotating shaft, and the outer surface of the cleaning plate is in contact with the inner wall of the cylinder body.

By driving the driven gear to rotate through the driving gear, the rotating shaft is driven to drive the scraping plate, the stirring rod and the cleaning plate to rotate, thereby cleaning the filter screen and the cylinder body, preventing the filter screen from being easily blocked, avoiding impurities adhering to the inner wall of the cylinder body, and at the same time assisting the discharge of the accumulated impurities to prevent the impurities from blocking the sewage discharge port.

[0008] Further, a first sealing ring is arranged inside the upper cover, and a second sealing ring is arranged inside the lower cover.

[0009] Through the above solution, the sealing effect of the upper cover and the lower cover is improved, and the liquid is prevented from leaking out easily.

[0010] Further, equally spaced columns are fixedly connected to the upper surface of the support ring, the inside of the filter screen is slidably sleeved on the outer circumferential surface of the columns, and a nut is threadedly connected to the outer circumferential surface of each column.

[0011] Through the above solution, the filter screen and the support ring are connected and fixed through the columns and nuts, increasing the stability of the filter screen.

[0013] Through the above solution, the driven gear is driven to rotate during the rotation of the driving gear, so that the rotating shaft drives the scraping plate, the stirring rod and the cleaning plate to rotate, providing power for the rotating shaft.

[0014] Further, a first limiting ring is fixedly sleeved on the outer circumferential surface of the rotating shaft, and the outer circumferential surface of the first limiting ring is rotatably connected to the inside of the fixed seat.

[0015] Through the above solution, the rotating shaft is restricted to prevent the rotating shaft from sliding and shifting, and the stability of the movement of the rotating shaft is increased.

[0016] Further, four control rods arranged at equal intervals are rotatably inserted into the inside of the upper cover. A positioning rod is threadedly connected to the outer circumferential surface of each control rod. Four positioning holes arranged at equal intervals are formed in the outer circumferential surface of the cylinder body, and the outer circumferential surface of the positioning rod is slidably inserted into the cylinder body through the positioning holes.

[0017] Through the above solution, the control rod can be rotated to drive the positioning rod to move into or out of the positioning hole, which is convenient for the installation and disassembly of the upper cover.

[0018] Further, a second limiting ring is fixedly sleeved on the outer circumferential surface of each control rod, and the outer circumferential surface of the second limiting ring is rotatably connected to the inside of the upper cover.

[0019] Through the above solution, the control rod is restricted to prevent the control rod from sliding and shifting, and the stability of the movement of the control rod is increased.

[0020] Further, two limiting blocks are fixedly connected to the outer circumferential surface of each positioning rod, and the outer surfaces of the limiting blocks are slidably connected to the upper cover through the empty grooves formed in the inside of the upper cover.

[0021] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the control rod, and the positioning rod is always moved horizontally.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For this new type of basket filter, the driving gear drives the driven gear to rotate, so that the rotating shaft drives the scraper, the stirring rod and the cleaning plate to rotate at the same time, achieving the effect of being able to clean the filter screen and the cylinder body, preventing the filter screen from being easily blocked, and also preventing impurities from adhering to the inner wall of the cylinder body. At the same time, it can also assist the discharge of the accumulated impurities and prevent the impurities from blocking the sewage outlet, solving the problem that the filter screen of the existing filter may still be blocked by impurities during the operation process. Once the filter screen is blocked, it will affect the filtration operation efficiency, and the impurities may cause the blockage of the sewage outlet during the discharge process, affecting the normal sewage discharge operation.

Once the filter screen 3 is blocked, the filtration operation efficiency will be affected, and the impurities may cause blockage of the sewage outlet 8 during the discharge process, affecting the normal sewage discharge operation.

[0042] It should be noted that a handle is provided on the upper surface of the upper cover 6, and the upper cover 6 can be taken and placed through the handle.

[0043] The working principle of the above embodiment is as follows:

[0044] When filtration operation is required, the liquid is injected into the cylinder body 1 from the feed port 4. The liquid will move upward through the filter screen 3 and finally flow out through the discharge port 5. The impurities in the liquid will be intercepted by the filter screen 3 inside the cylinder body 1. The lower cover 9 can be unscrewed regularly for sewage discharge. During the sewage discharge process, the motor 18 can be started as the power to drive the driving gear 19 to rotate through the output shaft. The driving gear 19 drives the rotating shaft 14 to rotate through the driven gear 20. The rotating shaft 14 drives the scraper 15, the stirring rod 16 and the cleaning plate 17 to rotate at the same time. During the rotation process, the scraper 15 can scrape off the impurities on the filter screen 3 to prevent the filter screen 3 from being easily blocked. During the rotation process of the cleaning plate 17, the impurities adhering to the inside of the cylinder body 1 can be cleaned to prevent the impurities from adhering to the cylinder body 1. During the rotation process of the stirring rod 16, the impurities at the bottom of the cylinder body 1 can be stirred to assist the discharge of the impurities and prevent the impurities from blocking the sewage outlet 8. If the filtration efficiency is low during the filtration operation, the motor 18 can also be started to drive the scraper 15 to clean the filter screen 3 to ensure the filtration quality and improve the filtration efficiency. When the filter screen 3 needs to be disassembled and maintained, the control rod 22 can be rotated to drive the positioning rod 23 to move out of the positioning hole 24, canceling the positioning restriction of the positioning rod 23 on the upper cover 6. Then the upper cover 6 can be removed, and the nut 12 can be unscrewed to remove the filter screen 3 for maintenance.
