Description
Technical Field
[0001] This utility model belongs to the field of flow controllers, specifically, it relates to an anti-clogging liquid flow controller. Background Technology
[0002] Flow controllers are widely used in automatic flow control systems in industries such as chemical, petroleum, metallurgy, and power. A flow controller typically consists of a flow meter, a digital controller, an electric actuator, and a regulating valve.
[0003] Chinese patent CN207261695U discloses a clog-resistant, alkali-resistant, high-pressure flow controller, comprising: a liquid inlet located at the upper part of the housing, a filter screen at the inlet to block particulate matter in the liquid and prevent clogging of the liquid channel inside the housing; a drain port located on the housing next to the filter screen, with a sealing cap at the drain port for periodically cleaning solids accumulated on the filter screen; a liquid passage and a blocking port located at the lower part of the liquid inlet; and a liquid outlet located at the lower part of the housing, with a flow sensor installed on the inner wall of the outlet for monitoring the flow rate at the outlet. This application, by utilizing the drain port in conjunction with the sealing cap, facilitates the periodic cleaning of particulate matter accumulated on the filter screen. However, in normal use, the accumulation of particulate matter on the filter screen surface can easily obstruct the normal flow of liquid, leading to frequent cleaning. In addition, the content of particulate matter in the liquid is not constant, which can easily lead to the failure to keep up with manual cleaning in a timely manner. Although existing technologies use rotating brushes or scrapers on the filter screen surface to scrape away particulate matter and extend the cleaning cycle, the scraped particulate matter will still accumulate on the surface of the filter screen, causing blockage of some mesh holes, thus affecting the liquid flow rate to some extent.

Detailed Implementation
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] Please see Figure 1-6 As shown, this embodiment provides an anti-clogging liquid flow controller, including: The housing 2 has an inlet pipe 201 on its upper side and an outlet pipe 202 on its side. The upper end face of the inlet pipe 201 is equipped with a first flange 3. The lower part of the housing 2 is fitted with a sludge collection box 4. The inlet pipe 201, the outlet pipe 202 and the sludge collection box 4 are all connected to the inner cavity of the housing 2. Locking mechanism 5 is used to limit the movement of the sludge collection box 4; A flow controller body 1 is included. A filter element 7 is detachably installed between the flow controller body 1 and the outlet pipe 202. One end of the filter element 7 extends into the housing 2. A cross-shaped connecting rod 8 is rotatably fitted to one end face of the filter element 7. Each of the four ends of the cross-shaped connecting rod 8 is equipped with a scraper 802. Rotation drive mechanism 6 for driving the cross-shaped connecting rod 8 to rotate.
[0020] One application of this embodiment is as follows: During use, liquid is supplied to the inlet pipe 201 via an external device, allowing the liquid to enter the housing 2. Then, the liquid inside the housing 2 flows to the flow controller body 1 through the outlet pipe 202. During this process, the filter element 7 filters particulate impurities in the liquid, and the liquid flow rate can be controlled by adjusting the flow controller body 1. Simultaneously, the rotation drive mechanism 6 can be activated to drive the cross-shaped connecting rod 8 and the scraper 802 to rotate. The rotation of the scraper 802 scrapes off the particulate impurities attached to the surface of the filter element 7, and the scraped-off particulate impurities settle into the sludge collection box 4 for collection. When a certain amount has been collected, the locking mechanism 5 can be moved upwards to release the restriction on the sludge collection box 4. The sludge collection box 4 can then be removed for cleaning of the internal particulate impurities. Finally, the cleaned sludge collection box 4 is reset, causing the locking mechanism 5 to re-restrict the sludge collection box 4. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.
[0021] The rotating drive mechanism 6 drives the cross-shaped connecting rod 8 and the scraper 802 to rotate, which facilitates continuous cleaning of the surface of the filter element 7 and shortens the time that particulate matter stays on the surface of the filter element 7. At the same time, the sludge collection box 4 collects the scraped-off debris, reducing the probability of particulate matter accumulating on the surface of the filter element 7 and greatly extending the cleaning cycle. The locking mechanism 5 limits and releases the sludge collection box 4, improving cleaning efficiency and maintenance convenience.
[0022] Specifically, a retaining ring 803 is installed at one end of each of the four scrapers 802, and the retaining ring 803 is located around the filter element 7. The retaining ring 803 helps to improve the stability of the scraper 802 during rotation and reduces the risk of the scraper 802 shifting or breaking during rotation.
[0023] To facilitate the disassembly of the cross-shaped connecting rod 8 and to improve its stability during rotation, its specific structure is as follows: Figure 2 , 3 As shown in Figure 5, a rotating column 805 is installed on one side of the middle part of the cross-shaped connecting rod 8. One end of the rotating column 805 extends into the filter element 7. A screw hole 806 is provided on one end face of the rotating column 805. A bolt 804 is provided inside the filter element 7. One end of the bolt 804 is threaded into the screw hole 806.
[0024] The screw hole 806 and bolt 804 cooperate to realize the detachable connection between the cross-shaped connecting rod 8 and the filter element 7, which facilitates the disassembly of the scraper 802 and the filter element 7. The scraper 802 cooperates with the filter element 7 through the detachable cross-shaped connecting rod 8, which reduces the replacement cost of the scraper 802 or the filter element 7. The rotating column 805 serves as the central axis of rotation of the cross-shaped connecting rod 8, which improves the stability of the cross-shaped connecting rod 8 when rotating.
[0025] To facilitate the disassembly and assembly of the rotation drive mechanism 6 and the cross-shaped connecting rod 8, its specific structure is as follows: Figure 2 , 3 As shown in Figure 5, a cross-shaped groove 801 is provided in the middle of the cross-shaped connecting rod 8, and the driving end of the rotation drive mechanism 6 is inserted into the cross-shaped groove 801.
[0026] The cross-shaped groove 801 facilitates the engagement of the cross-shaped connecting rod 8 onto the rotary drive mechanism 6, thereby enabling the rotary drive mechanism 6 to drive the cross-shaped connecting rod 8 to rotate.
[0027] To ensure that the rotary drive mechanism 6 can drive the cross-shaped connecting rod 8 to rotate stably and reduce slippage, its specific structure is as follows: Figure 2 , 3 As shown in Figure 6, the rotation drive mechanism 6 includes a motor 601 mounted on one side of the housing 2. The output shaft of the motor 601 extends into the housing 2, and a cross-shaped drive block 602 is fixedly fitted to the output shaft of the motor 601. The cross-shaped drive block 602 is located in the cross-shaped groove 801.
[0028] By turning on the motor 601, the cross-shaped drive block 602 is driven to rotate. The rotation of the cross-shaped drive block 602 drives the cross-shaped connecting rod 8 and the scraper 802 to rotate through the cross-shaped groove 801, which realizes the convenience of disassembly and assembly. At the same time, through the cooperation of the cross-shaped drive block 602 and the cross-shaped groove 801, the drive of the cross-shaped drive block 602 on the cross-shaped connecting rod 8 is more stable.
[0029] To enable quick positioning and disassembly of the sludge collection box 4, its specific structure is as follows: Figure 1 , 4 As shown. The locking mechanism 5 includes a trapezoidal slider 502, which is elastically and slidably fitted inside the housing 2. A T-shaped lever 501 is installed on one side of the trapezoidal slider 502, and the end of the T-shaped lever 501 near the trapezoidal slider 502 is slidably fitted inside the housing 2.
[0030] The trapezoidal slider 502 works in conjunction with the T-shaped lever 501 to limit and unlock the sludge collection box 4, while also allowing the user to operate the T-shaped lever 501 with one hand, thus improving the speed of disassembly and installation.
[0031] Specifically, the lower side of the housing 2 is provided with a first slide groove 203, and a spring 503 is installed on the upper side of the first slide groove 203. The trapezoidal slider 502 is installed at the lower end of the spring 503. The spring 503 rebounds to facilitate pushing the trapezoidal slider 502 to slide down and reset; the first slide groove 203 provides sliding guidance for the trapezoidal slider 502.
[0032] Specifically, a second slide groove 204 communicating with the first slide groove 203 is provided on one side of the lower part of the housing 2. The end of the T-shaped lever 501 near the trapezoidal slider 502 is slidably engaged in the second slide groove 204. The second slide groove 204 allows the user to slide the trapezoidal slider 502 inside the housing 2 from the outside using the T-shaped lever 501.
[0033] To ensure more stable sliding of the sludge collection box 4 and to facilitate its pulling out, its specific structure is as follows: Figure 1 , 2 As shown in Figure 4, an L-shaped handle 401 is installed on one side of the upper part of the sludge collection box 4, and U-shaped strips 403 are provided on the other three sides. The upper surfaces of the L-shaped handle 401 and the U-shaped strips 403 are both coated with a rubber sealing layer. A square groove 206 is provided on the lower side of the housing 2. The upper part of the sludge collection box 4 is located in the square groove 206. U-shaped grooves 205 are provided on the three sides of the square groove 206. The U-shaped strips 403 are engaged in the U-shaped grooves 205. Both the U-shaped grooves 205 and the square grooves 206 penetrate one side of the housing 2.
[0034] The L-shaped handle 401 facilitates the user's pulling out of the sludge collection box 4; the square groove 206 and the U-shaped groove 205 cooperate to provide guidance and support for the sludge collection box 4.
[0035] Specifically, a locking groove 402 passes through the upper middle part of the horizontal side of the L-shaped handle 401, and the lower part of the trapezoidal slider 502 passes through the locking groove 402. The lower part of the trapezoidal slider 502 is located between the sludge collection box 4 and the vertical side of the L-shaped handle 401. The locking groove 402 facilitates the locking mechanism 5 to limit the sludge collection box 4.
[0036] To achieve the filtration of liquid by filter element 7, its specific structure is as follows: Figure 2 , 3 As shown in Figure 4, the filter element 7 includes a filter cover 701, a cross-shaped connecting rod 8 located at one end face of the filter cover 701, a fixing ring 803 located on the periphery of the end of the filter cover 701 away from the cross-shaped connecting rod 8, a scraper 802 located on the side of the filter cover 701, and the gap between the cutting edge of the scraper 802 and the outer surface of the filter cover 701 is 0.1mm to 0.5mm to reduce scratches caused by the cutting edge of the scraper 802 on the surface of the filter cover 701. A connecting ring 702 is installed at the opening of the filter cover 701, and the connecting ring 702 is located inside the liquid outlet pipe 202. A second flange 703 is installed on one end face of the connecting ring 702.
[0037] The filter cover 701 is used to filter particulate impurities in the liquid and increases the filtration area; the connecting ring 702 makes it easy to extend the distance of the filter cover 701 so that the filter cover 701 can be located inside the housing 2.
[0038] To enable the disassembly and assembly of the filter cover 701, its specific structure is as follows: Figure 1 , 2 As shown in Figure 5, both ends of the flow controller body 1 are equipped with connecting pipes 101. A third flange 102 is installed on one end face of the connecting pipe 101. The second flange 703, the third flange 102 and the outlet pipe 202 are assembled by bolts.
[0039] The detachable connection between the second flange 703, the third flange 102 and the outlet pipe 202 enables the filter cover 701 to be clamped and fixed, reducing the risk of the filter cover 701 falling off due to liquid impact. At the same time, it enables the filter cover 701 to be detachable, facilitating subsequent maintenance and replacement.
