Description

Technical Field

[0001] The present invention relates to the technical field of filters, and specifically to an environmental protection filter with a continuous sewage and sediment cleaning function. Background Art

[0002] During the treatment and filtration of factory sewage, most of the sewage is discharged into a sedimentation tank to precipitate large-mass pollution particles first, and then the sewage is filtered, disinfected, and purified through a filter before being discharged. However, after the filter has filtered sewage for a long time, the mesh holes on the filter element are easily blocked, resulting in the sewage being unable to be quickly discharged from the filter, reducing the sewage filtration effect.

[0003] According to the patent document with the publication number CN113499626B, in this device, a driving motor drives a rotating rod to rotate, so that a cleaning brush drives the bristles to rotate to clean the surface of the filter cylinder, avoiding impurities from blocking the filter holes and the mesh holes of the filter element.

[0004] However, in the above patent document, when the content of sediment impurities in the sewage increases and continuous cleaning is carried out by the brush, there will be a problem of incomplete cleaning in a few cases. It is difficult to comprehensively analyze and supervise the blockage and damage conditions of the mesh holes on the outer wall of the filter cylinder, and according to the signals obtained from the analysis, timely further clean or repair and replace the filter cylinder, so as to improve the sewage filtration quality. At the same time, when there is too much sediment in the sewage, it is easy to cause sediment blockage of the sewage discharge pipe. It is difficult to synchronously avoid sewage discharge pipe blockage during the continuous cleaning of the filter cylinder, which affects the sewage filtration.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0024] 1. In the present invention, by rotating the inner sleeve, the scraper and the stirring rod rotate in the opposite direction relative to the filter cylinder, scraping off a small amount of impurities adhering to the inner wall of the filter cylinder. At the same time, the stirring rod stirs the inside of the output end of the filter cylinder and the sewage discharge pipe, preventing the sewage discharge pipe from being blocked by excessive sediment, thereby affecting the sewage discharge effect. When the reciprocating screw rod rotates, the T-block is limited by the connecting rod, causing the cleaning ring to continuously reciprocate along the outer wall of the filter cylinder, realizing continuous cleaning of its outer wall. This device cooperates with the soft brush outside the filter cylinder and the scraper inside the filter cylinder to continuously clean the filter cylinder, and simultaneously prevents the sewage discharge pipe from being blocked, thus affecting the filtration of sewage.

[0025] 2. In the present invention, by collecting the damage value and the outer wall occlusion value of the filter cylinder, a comprehensive analysis and supervision of the outer wall of the filter cylinder are carried out during the process of the filter cylinder filtering sewage. The outer wall self-inspection module analyzes the outer wall condition of the filter cylinder and sends the obtained processing signal to the execution module.

[0041] On the outer side of the cleaning ring 619, there is a pressurizing component for adjusting the position of the soft brush 625. The pressurizing component includes a reciprocating lead screw 612 arranged on the outer side of the filter cylinder 1. The outer wall of the reciprocating lead screw 612 is connected with a hollow box 69 through a T-block 611. A gasbag 610 is fixedly arranged on the side wall of the hollow box 69.

[0042] Gas enters the air box 613 and then is discharged into the pressurizing area of the hollow box 69 through the telescopic pipe 616, causing the gasbag 610 to continuously fill;

[0043] On one side of the hollow box 69, there is an air delivery component, and a transmission component is arranged at the bottom of the air delivery component;

[0044] An inner cleaning mechanism is arranged inside the filter cylinder 1. The inner cleaning mechanism includes a scraper 81 arranged on the inner side wall of the filter cylinder 1. One end of the scraper 81 is fixedly provided with a stirring rod 82.

[0045] An outer sleeve 2 is fixedly inserted at the input end of the filter cylinder 1. An inner sleeve 3 is rotatably arranged inside the outer sleeve 2 through a bearing. A sewage discharge pipe 4 is fixedly inserted at the output end of the filter cylinder 1. Two partition plates 9 are respectively rotatably matched with the outer sleeve 2 and the sewage discharge pipe 4. The other end of the scraper 81 is fixedly connected with the inner sleeve 3. The stirring rod 82 is located inside the sewage discharge pipe 4.

[0046] When the inner sleeve 3 rotates, the scraper 81 and the stirring rod 82 rotate in the opposite direction relative to the filter cylinder 1, scraping off a small amount of impurities adhering to the inner wall of the filter cylinder 1. At the same time, the stirring rod 82 stirs the inside of the output end of the filter cylinder 1 and the sewage discharge pipe 4, preventing the sewage discharge pipe 4 from being blocked due to excessive sediment, thus affecting the sewage discharge effect;

[0047] The transmission component includes a bevel gear one 61 fixedly connected to the outer wall of the inner sleeve 3. A bevel gear two 62 is fixedly arranged on the outer wall of the outer sleeve 2. A bevel gear three 63 is meshed and connected between the bevel gear one 61 and the bevel gear two 62. A driving shaft 64 is fixedly arranged at the center of the bevel gear three 63. A motor is fixedly arranged at the top of the driving shaft 64. An L-shaped rod 67 is rotatably arranged on the outer wall above the driving shaft 64. A bevel gear four 65 is fixedly arranged on the outer wall in the middle of the driving shaft 64;

[0048] The top of the L-shaped rod 67 is fixedly connected to the inner wall of the housing 10. The side wall of the driving shaft 64 is fixedly connected to the housing 10 through a cross bar;

[0049] Control the motor to make the driving shaft 64 rotate, synchronously driving the rotation of the bevel gear three 63 and the bevel gear four 65, so that the outer sleeve 2, the inner sleeve 3, the reciprocating lead screw two 614 and the reciprocating lead screw one 612 rotate synchronously;

[0050] The gas delivery component includes a reciprocating screw rod two 614 rotatably connected to the bottom of the L-shaped rod 67 through a bearing. One end of the reciprocating screw rod two 614 is fixedly provided with a bevel gear five 66, which is meshed and connected with a bevel gear four 65. A gas tank 613 is rotatably arranged on the outer wall of the reciprocating screw rod two 614. A piston plate 615 is threadedly connected to the outer wall of the reciprocating screw rod two 614 located inside the gas tank 613. The gas tank 613 is communicated with the pressurizing area through a telescopic pipe 616. An air inlet pipe 617 and a control pipe 618 are fixedly inserted into the side wall of the gas tank 613. The other end of the reciprocating screw rod two 614 is fixedly connected to the reciprocating screw rod one 612;

[0051] A control valve one is arranged on the outer wall of the telescopic pipe 616, a one-way valve is arranged on the outer wall of the air inlet pipe 617, and a control valve three is arranged on the outer wall of the control pipe 618;

[0052] When the reciprocating screw rod two 614 rotates, the piston plate 615 continuously reciprocates inside the gas tank 613, allowing gas to enter the gas tank 613 through the air inlet pipe 617 and then be discharged into the hollow box 69 through the telescopic pipe 616, causing the airbag 610 to continuously fill. When the filling degree of the airbag 610 reaches the maximum value, the control valve one on the telescopic pipe 616 is closed, and the control valve three on the control pipe 618 is opened to prevent gas from entering the hollow box 69 again.

[0053] A connecting rod 68 is slidably arranged above the T-shaped block 611. One end of the connecting rod 68 is fixedly provided with a limiting rod 5, the other end of the connecting rod 68 is fixedly connected to the L-shaped rod 67, and the top of the gas tank 613 is fixedly connected to the connecting rod 68;

[0054] The top of the limiting rod 5 is fixedly connected to the housing 10, and the bottom of the limiting rod 5 is rotatably matched with the sewage pipe 4.

[0055] A conveying ring 621 is formed on the inner wall of the outer side of the cleaning ring 619. The input end of the conveying ring 621 is communicated with a conveying pipe 620. A plurality of sliding grooves 622 are formed on the inner wall of the inner side of the cleaning ring 619. A sliding rod 623 is slidably arranged in the sliding grooves 622. One end of the sliding rod 623 close to the filter cylinder 1 is fixedly connected to an arc-shaped plate 624. A tension spring is arranged between the sliding grooves 622 and the sliding rod 623, and the output end of the conveying ring 621 is communicated with the sliding grooves 622;

[0056] When the airbag 610 quickly contracts, the gas in the hollow box 69 is squeezed into the conveying ring 621, then conveyed into the sliding grooves 622 to squeeze the sliding rod 623, so that the soft brush 625 on the arc-shaped plate 624 further closely adheres to the outer wall of the filter cylinder 1, increasing the cleaning efficiency of the filter cylinder 1;

[0057] By opening the control valve two, the control valve one and the control valve three, the tension spring can reset the arc-shaped plate 624 through the sliding rod 623.

[0058] Embodiment 2: A processor, a data acquisition module, an outer wall self-check module, a warning module, and an execution module are arranged in the control panel 11 of this embodiment;

[0059] The data acquisition module is used to collect the outer wall damage value and the outer wall occlusion value of the filter cartridge 1 within the time threshold, and send them to the outer wall self-check module through the processor;

[0060] Here, it should be noted that the time threshold is represented as the duration of the filter cartridge 1 filtering for 2 hours; the outer wall damage value is represented as the number of protrusions or depressions on the outer wall of the filter cartridge 1 within the 2-hour time threshold. The larger the outer wall damage value, the greater the damage to the filter cartridge 1 and the more maintenance is required; the outer wall occlusion value is represented as the blocked area of the mesh holes on the outer wall surface of the filter cartridge 1 within the 2-hour time threshold. The larger the outer wall occlusion value, the worse the cleaning effect of the outer wall surface, and the cleaning intensity needs to be increased to improve the cleaning effect;

[0061] The blocked area of the mesh holes on the outer wall surface of the filter cartridge 1 is collected by an image sensor; the number of protrusions or depressions on the outer wall of the filter cartridge 1 is collected by a structured light sensor, and both the structured light sensor and the image sensor are arranged on the top wall inside the housing 10.

[0062] After receiving the outer wall damage value and the outer wall occlusion value, the outer wall self-check module immediately analyzes the outer wall condition of the filter cartridge 1. The specific analysis process is as follows: Obtain the outer wall damage value and the outer wall occlusion value within the time threshold, and mark the outer wall damage value and the outer wall occlusion value as Wi and Wz respectively, and obtain the mesh barrel interference coefficient Pi through the formula Pi = (wi * a1 + wz 2 * a2) / 3, where a1 and a2 are the proportionality coefficients of the outer wall damage value Wi and the outer wall occlusion value Wz respectively, and a1>0, a2>0. Immediately retrieve the preset mesh barrel interference coefficient stored in the processor and compare it with the mesh barrel interference coefficient Pi for analysis:

[0063] If the mesh barrel interference coefficient Pi is greater than or equal to the preset mesh barrel interference coefficient, it is determined that there is an abnormality in the outer wall filtration of the filter cartridge 1, a processing signal is generated, and the processing signal is sent to the execution module through the processor. After receiving the processing signal, the execution module immediately opens the second control valve, causing the airbag 610 to quickly contract, squeezing the gas in the hollow box 69 into the conveying ring 621, and then conveying it into the chute 622 to squeeze the sliding rod 623, so that the soft brush 625 on the arc-shaped plate 624 further clings to the outer wall of the filter cartridge 1, increasing the cleaning efficiency of the filter cartridge 1;

[0064] If the mesh barrel interference coefficient Pi is less than the preset mesh barrel interference coefficient, no signal is generated;

[0065] When the processor sends a processing signal to the execution module, the processor synchronously obtains the outer wall damage value Wi that generates the processing signal, and sends the obtained outer wall damage value Wi to the warning module. After receiving the outer wall damage value Wi, the warning module immediately retrieves the preset outer wall damage value stored and entered in the processor and compares and analyzes it with the outer wall damage value Wi:

[0066] If the outer wall damage value Wi is greater than or equal to the preset outer wall damage value, it is determined that there is a damage problem on the outer wall of the filter mesh hole, and a warning signal is generated. The warning signal is converted into text by the processor and sent to the mobile terminal for later maintenance or replacement;

[0067] If the wall damage value Wi is less than the preset outer wall damage value, no signal is generated.

[0068] The working process and principle of the present invention are as follows:

[0069] Sewage enters the filter cylinder 1 through the inner sleeve 3 and is then discharged through the sewage discharge pipe 4, so that the filter cylinder 1 continuously filters the sediment in the sewage. At the same time, the motor is controlled to make the drive shaft 64 rotate, synchronously driving the rotation of the bevel gear three 63 and the bevel gear four 65, so that the outer sleeve 2, the inner sleeve 3, the reciprocating screw rod two 614 and the reciprocating screw rod one 612 rotate synchronously;

[0070] The rotation of the outer sleeve 2 makes the filter cylinder 1 rotate, and the sediment filtered inside the filter cylinder 1 is discharged through the sewage discharge pipe 4;

[0071] The rotation of the inner sleeve 3 makes the scraper 81 and the stirring rod 82 rotate in the opposite direction relative to the filter cylinder 1, scraping off a small amount of impurities adhering to the inner wall of the filter cylinder 1. At the same time, the stirring rod 82 stirs the inside of the output end of the filter cylinder 1 and the sewage discharge pipe 4 to prevent the sewage discharge pipe 4 from being blocked due to excessive sediment, thus affecting the sewage discharge effect;

[0072] The rotation of the reciprocating screw rod two 614 makes the piston plate 615 continuously reciprocate inside the air box 613, allowing gas to enter the air box 613 through the air inlet pipe 617 and then be discharged into the hollow box 69 through the telescopic pipe 616, so that the airbag 610 is continuously filled. When the filling degree of the airbag 610 reaches the maximum value, the control valve one on the telescopic pipe 616 is closed, and the control valve three on the control pipe 618 is opened. When a processing signal is obtained, the control valve two on the delivery pipe 620 is opened, so that the airbag 610 quickly contracts, squeezing the gas in the hollow box 69 into the delivery ring 621 and then transporting it into the chute 622 to squeeze the slide rod 623, so that the soft brush 625 on the arc-shaped plate 624 further closely adheres to the outer wall of the filter cylinder 1, increasing the cleaning efficiency of the filter cylinder 1;

[0073] When the reciprocating lead screw 612 rotates, the T-block 611 is restricted by the connecting rod 68, causing the cleaning ring 619 to continuously reciprocate along the outer wall of the filter cartridge 1, achieving continuous cleaning of its outer wall. Then, continuous cleaning of the filter cartridge 1 is realized through the soft brush 625 on the outside of the filter cartridge 1 and the scraper 81 inside the filter cartridge 1, always keeping the filter cartridge 1 relatively clean and improving the filtering effect.
