Description

Technical Field

[0001] This application relates to the technical field of fluid impurity filtration, and specifically relates to a non-detachable online self-cleaning basket filter. Background Art

[0002] The basket filter is installed on a gas or liquid pipeline, and its function is to filter and intercept solid impurity particles such as welding slag, rust, sediment, and dust entrained in various fluids, thereby avoiding blockage and damage of pipelines, pumps, valves, and equipment, etc., to protect the normal operation of the equipment and ensure safe production.

[0003] A prior patent (publication number: CN211328367U) discloses a non-detachable online self-cleaning basket filter, including a cylinder body and a filter basket. An inlet and an outlet are respectively provided on both sides of the cylinder body, a flange top cover is provided on the top of the cylinder body, and a drain pipe with a built-in drain valve is provided at the bottom of the cylinder body. It is characterized in that: the filter basket is a tapered cylindrical filter net that runs through the upper part to the lower part of the cylinder body, and the lower end is open; the top end of the filter basket is an inclined section, one end abuts against the horizontal section at the lower end of the inlet, the other end abuts against the horizontal section at the upper end of the outlet and is flush with the flange top cover; the bottom of the filter basket is hermetically connected to the cylinder body, and the lower end of the filter basket communicates with the drain pipe at the bottom of the cylinder body.

[0004] The above-mentioned comparative document points out that the fluid flows into the filter basket from the inlet of the filter. The impurities in the fluid are intercepted by the tapered cylindrical filter net and accumulate at the bottom of the filter basket. When cleaning is required, the drain valve of the drain pipe is directly opened, and the accumulated impurities at the bottom of the filter basket will be discharged from the drain port along with the fluid. The tapered cylindrical filter basket is prone to accumulating dirt, and the cross-sectional area of the filter basket becomes smaller, which can increase the flushing force and facilitate flushing and sewage discharge. However, the fluid is uneven when entering the filter basket. If the distribution of the fluid in the filter basket is uneven, it may lead to a decrease in the filtration efficiency. Due to the uneven distribution of the fluid, the flushing effect may be inconsistent during the flushing process. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, this application provides a non-detachable online self-cleaning basket filter, which has the advantages of increasing the self-cleaning effect, etc., and solves the problem that the fluid flows into the filter basket from the inlet of the filter, the impurities in the fluid are intercepted by the tapered cylindrical filter net and accumulate at the bottom of the filter basket. When cleaning is required, the drain valve of the drain pipe is directly opened, and the accumulated impurities at the bottom of the filter basket will be discharged from the drain port along with the fluid. The tapered cylindrical filter basket is prone to accumulating dirt, and the cross-sectional area of the filter basket becomes smaller, which can increase the flushing force and facilitate flushing and sewage discharge. However, the fluid is uneven when entering the filter basket. If the distribution of the fluid in the filter basket is uneven, it may lead to a decrease in the filtration efficiency. Due to the uneven distribution of the fluid, the flushing effect may be inconsistent during the flushing process.

[0006] To achieve the above object, the present application provides the following technical solution: a detachable online self-cleaning basket filter, including a housing, a filter basket is fixedly connected inside the housing, a water inlet pipe is fixedly connected to the upper end of the outer wall of the housing, a water distribution ring is fixedly connected to one end of the water inlet pipe passing through the filter basket, and a spray head is fixedly connected to the bottom end of the water distribution ring.

[0007] Through the above solution, through the setting of the water distribution ring and the spray head, it is ensured that the fluid can be evenly distributed when entering the filter basket. This uniform fluid distribution can effectively improve the filtration efficiency of the filter basket. Since the fluid is evenly distributed, each part of the filter basket can make full use of its filtration capacity, thus improving the overall filtration efficiency. During self-cleaning, due to the uniform flushing of the inside of the filter basket by the spray head, the impurities inside the filter basket are evenly washed to the bottom end of the filter basket, thereby increasing the cleaning effect.

[0009] Through the above solution, by driving the rotation of the rotating shaft by the motor, the support frame and the scraper are driven to rotate, realizing the automatic cleaning function. This design eliminates the need for manual disassembly of the filter for cleaning, greatly improving the cleaning efficiency and convenience. The scraper can thoroughly scrape off the impurities accumulated on the inner wall of the filter basket, ensuring the cleanliness and filtration efficiency of the filter basket.

[0010] Further, a water outlet pipe is fixedly connected to the bottom end of the outer wall of the housing.

[0011] Through the above solution, the setting of the water outlet pipe enables the filtered liquid to be conveniently discharged from the filter.

[0012] Further, a sewage pipe is fixedly connected to the bottom end of the filter basket.

[0013] Through the above solution, the design of the sewage pipe can timely discharge the sewage and impurities at the bottom of the filter basket.

[0014] Further, the sewage pipe penetrates through the bottom end of the housing, and a solenoid valve is fixedly connected to one end of the outer wall of the sewage pipe away from the filter basket.

[0015] Through the above solution, by controlling the opening and closing of the solenoid valve, the discharge of the sewage pipe can be accurately controlled. When it is necessary to discharge sewage and impurities, the solenoid valve is opened, and the sewage and impurities are discharged smoothly; when it is not necessary to discharge, the solenoid valve is closed, avoiding the loss and waste of liquid, realizing the automatic control of the filter, and improving the operation efficiency.

[0016] Further, the water separation ring is fixedly arranged inside the filter basket.

[0017] Through the above solution, the water separation ring may be used to divert the fluid inside the filter basket, making it more evenly distributed inside the filter basket, thereby improving the filtering effect and efficiency.

[0018] Further, the support frame is rotatably arranged inside the filter basket.

[0019] Through the above solution, the motor drives the support frame to rotate inside the filter basket.

[0020] Further, one end of the scraper away from the support frame is in close contact with the inner wall of the filter basket.

[0021] Through the above solution, when the support frame drives the scraper to rotate, the close contact between the scraper and the inner wall of the filter basket can scrape off the materials or dirt attached to the inner wall, thereby realizing automatic cleaning.

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

[0023] For the detachable online self-cleaning basket filter, through the settings of the water separation ring and the spray head, it is ensured that the fluid can be evenly distributed when entering the filter basket. This uniform fluid distribution can effectively improve the filtering efficiency of the filter basket. Since the fluid is evenly distributed, each part of the filter basket can make full use of its filtering capacity, thereby improving the overall filtering efficiency. During self-cleaning, due to the uniform flushing of the inside of the filter basket by the spray head, the impurities inside the filter basket are evenly washed to the bottom end of the filter basket, thereby increasing the cleaning effect.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 , a non-detachable online self-cleaning basket filter in this embodiment includes a housing 1. A filter basket 2 is fixedly connected inside the housing 1. A water inlet pipe 3 is fixedly connected to the upper end of the outer wall of the housing 1. One end of the water inlet pipe 3 passing through the filter basket 2 is fixedly connected to a water distribution ring 4. A spray head 5 is fixedly connected to the bottom end of the water distribution ring 4. Through the settings of the water distribution ring 4 and the spray head 5, it is ensured that the fluid can be evenly distributed when entering the filter basket 2. This uniform fluid distribution can effectively improve the filtration efficiency of the filter basket. Since the fluid is evenly distributed, each part of the filter basket 2 can make full use of its filtration capacity, thereby improving the overall filtration efficiency. During self-cleaning, due to the uniform flushing of the inside of the filter basket by the spray head, the impurities inside the filter basket are evenly washed to the bottom end of the filter basket, thereby increasing the cleaning effect.

[0032] Please refer to Figure 2 and Figure 3 , an upper cover 6 is fixedly connected to the upper end of the housing 1. A motor 7 is fixedly connected to the upper end of the upper cover 6. One end of the output end of the motor 7 passing through the upper cover 6 is fixedly connected to a rotating shaft 8 through a coupling. A support frame 9 is fixedly connected to the bottom end of the outer wall of the rotating shaft 8. A scraper 10 is fixedly connected to one side of the support frame 9. By driving the rotation of the rotating shaft 8 by the motor 7, the support frame 9 and the scraper 10 are driven to rotate, realizing the automatic cleaning function. This design eliminates the need for manual disassembly of the filter for cleaning, greatly improving the cleaning efficiency and convenience. The scraper 10 can thoroughly scrape off the impurities accumulated on the inner wall of the filter basket, ensuring the cleanliness and filtration efficiency of the filter basket. A water outlet pipe 11 is fixedly connected to the bottom end of the outer wall of the housing 1. The setting of the water outlet pipe 11 enables the filtered liquid to be conveniently discharged from the filter. A sewage pipe 12 is fixedly connected to the bottom end of the filter basket 2. The design of the sewage pipe 12 can timely discharge the sewage and impurities at the bottom of the filter basket 2.

[0033] Please refer to Figure 2 、 Figure 3 and Figure 4, the sewage pipe 12 is arranged through the bottom end of the housing 1. One end of the outer wall of the sewage pipe 12 far from the filter basket 2 is fixedly connected with a solenoid valve 13. By controlling the opening and closing of the solenoid valve 13, the discharge of the sewage pipe 12 can be accurately controlled. When it is necessary to discharge sewage and impurities, the solenoid valve opens, and the sewage and impurities are discharged smoothly. When discharge is not required, the solenoid valve closes, avoiding the loss and waste of liquid, realizing the automatic control of the filter, improving the operation efficiency. The water distribution ring 4 is fixedly arranged inside the filter basket 2. The water distribution ring 4 may be used to divide the fluid inside the filter basket 2, making it more evenly distributed inside the filter basket, thereby improving the filtering effect and efficiency. The support frame 9 is rotatably arranged inside the filter basket 2. The motor drives the support frame to rotate inside the filter basket. One end of the scraper 10 far from the support frame 9 is in close contact with the inner wall of the filter basket 2. When the support frame 9 drives the scraper 10 to rotate, the close contact between the scraper 10 and the inner wall of the filter basket 2 can scrape off the materials or dirt attached to the inner wall, thus realizing automatic cleaning.

[0034] In this embodiment, for the detachable online self-cleaning basket filter, through the setting of the water distribution ring 4 and the nozzles 5, it is ensured that the fluid can be evenly distributed when entering the filter basket 2. This uniform fluid distribution can effectively improve the filtering efficiency of the filter basket. Since the fluid is evenly distributed, each part of the filter basket 2 can make full use of its filtering ability, thereby improving the overall filtering efficiency. During self-cleaning, due to the nozzles evenly flushing the inside of the filter basket, the impurities inside the filter basket are evenly washed to the bottom end of the filter basket, thereby increasing the cleaning effect.

[0035] It should be noted that multiple nozzles are inclined towards the inside of the filter basket, so that the fluid can flow evenly into the filter basket.

[0036] The working principle of the above embodiment is as follows:

[0037] The fluid enters the water distribution ring 4 through the water inlet pipe 3 to evenly distribute the fluid to the nozzles 5. The nozzles 5 evenly spray the fluid into the inside of the filter basket 2 to ensure the uniform distribution of the fluid in the filter basket 2. The fluid is filtered through the filter medium of the filter basket 2. The filtered clean fluid is collected inside the housing and discharged through the water outlet pipe 11 at the upper end of the housing 1. The motor 7 is started. The motor 7 drives the rotating shaft 8 to rotate, and the support frame 9 on the rotating shaft 8 rotates accordingly. The scraper 10 on the support frame 9 also rotates accordingly. Since the scraper 10 is in close contact with the inner wall of the filter basket 2, the rotation of the scraper 10 will scrape off the impurities and dirt on the inner wall of the filter basket 2. The washed impurities are discharged through the sewage pipe 12 at the bottom end of the filter basket 2. By controlling the opening and closing of the solenoid valve 13, the discharge of the sewage pipe 12 can be accurately controlled. After the cleaning is completed, the motor 7 and the solenoid valve 13 are closed, and the filter returns to the working state of continuous filtering.
