Description

Technical Field

[0001] The present invention relates to the field of water treatment, and in particular to a water treatment device with a self-checking function. Background Art

[0002] During operation, the water treatment device uses built-in sensors and detection instruments to monitor the quality of filtered water in real time to detect whether the water quality meets preset standards, such as pollutant content, pH value and other indicators. If the water quality is found to be unqualified, the device will automatically issue an alarm and take corresponding measures, such as adjusting treatment parameters or activating the self-repair function, to ensure the water quality treatment effect and normal operation of the equipment, reduce manual monitoring costs, and improve the reliability and efficiency of water treatment.

[0003] In the process of sewage treatment, due to the different pollution levels of the input sewage, when the sewage is transported to the water treatment device for treatment, if the treatment capacity of the water treatment device remains unchanged and the sewage pollution level increases, the water quality of the treated sewage may not meet the requirements. At the same time, as the amount of sewage treated increases, the treatment effect of the water treatment device weakens, which may also cause the water quality of the treated sewage to not meet the requirements. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a water treatment device with a self-checking function.

[0005] The present invention provides a water treatment device with a self-checking function, comprising a filter box and further comprising:

[0006] A water inlet pipe is fixedly connected to the top of one side of the filter box;

[0007] A water outlet pipe is fixedly connected to the bottom of the other side of the filter box;

[0008] A top cover, detachably fixed to the top of the filter box;

[0009] Multiple multi-stage filter cores are installed inside the filter box. The multi-stage filter core located between the water inlet pipe and the water outlet pipe is called an immediate filter core. The multi-stage filter core located at the bottom of the immediate filter core is called a spare filter core. The water inside the filter box flows through the immediate filter core for filtration.

[0010] Two water quality detection components, respectively installed inside the water inlet pipe and the water outlet pipe, for performing water quality detection on the incoming and outgoing water flows;

[0011] A filter element adjustment component is installed inside the filter box and is used to dynamically adjust the multi-stage filter elements to enhance the filtering effect when poor quality of discharged water is detected;

[0012] The sewage enters the filter box along the water inlet pipe, then passes through the instant filter element inside the filter box, and then the filtered water is discharged along the outlet pipe, thereby achieving the filtration of the sewage;

[0013] The water quality detection components inside the water inlet pipe and the water outlet pipe detect the water quality of the incoming sewage and the water quality of the discharged water respectively;

[0014] When the water quality detection component detects that the water quality of the discharged water does not meet the requirements, the water quality detection component is started to detect the water quality of the incoming sewage. If it is detected that the pollution level of the incoming sewage has increased, it means that the pollution level of the sewage has increased, resulting in the water quality of the treated sewage not meeting the requirements. At this time, the filter element deployment component is started, and the filter element deployment component drives the top multi-stage filter element of the spare filter element to move upward, so that the top multi-stage filter element of the spare filter element moves to the bottom of the instant filter element. At this time, the sewage is filtered by the instant filter element and then passes through the moved multi-stage filter element for secondary filtration, thereby increasing the filtration of the sewage, so that the sewage with an increased pollution level can be filtered again, so that the filtered sewage meets the requirements;

[0015] If it is detected that the pollution level of the incoming sewage remains unchanged or weakened, it means that the filtering effect of the instant filter element has weakened after long-term use. At this time, the filter element deployment component is started, and the filter element deployment component drives the spare filter element and the instant filter element to move at the same time, so that the instant filter element moves upward to the inside of the top cover for storage, and the multi-stage filter element at the top of the spare filter element moves to the position between the water inlet pipe and the water outlet pipe and is called a new instant filter element, thereby automatically replacing the multi-stage filter element, which is beneficial for automatically replacing the multi-stage filter element when the filtering effect of the multi-stage filter element weakens after long-term use, thereby helping to maintain the filtering effect of sewage.

[0016] Preferably, the water quality detection component includes:

[0017] A detection box, fixedly connected to the middle portion of the water inlet pipe or the water outlet pipe;

[0018] A water quality detector, fixedly mounted on the inner wall of the detection box, for detecting water quality;

[0019] When sewage or filtered water flows through the interior of the test box, the water quality detector can detect the passing water flow, thereby being able to perform self-inspection of the filtered water quality in real time and to detect the incoming sewage.

[0020] Preferably, the water quality detection component further includes:

[0021] A stirring blade is rotatably installed inside the detection box;

[0022] A stirring motor is fixed to the outer wall of the detection box, and an output shaft of the stirring motor penetrates the side wall of the detection box and drives the stirring blade to rotate;

[0023] After the stirring motor is started, the output shaft drives the stirring blade connected to it to rotate. After the stirring blade rotates, it can stir the passing sewage or water flow, so that the water flow is uniform under the stirring action, which helps to avoid local water quality not meeting the standards or the local water quality pollution level being aggravated, and the water quality detector fails to detect it, resulting in affecting the judgment result.

[0024] Preferably, the filter element deployment component comprises:

[0025] A driving motor is fixed to the bottom of the filter box;

[0026] A plurality of threaded openings are respectively opened in the middle of the multi-stage filter element;

[0027] A drive screw is rotatably mounted inside the filter box. The output shaft of the drive motor penetrates the bottom of the filter box and drives the drive screw to rotate. The drive screw is threadably adapted to the threaded openings in multiple sections to drive the multi-stage filter element to move vertically.

[0028] A plurality of rubber gaskets are respectively fixed to the middle of each of the threaded openings to flexibly fill the gap between the threaded opening and the drive screw;

[0029] After the driving motor is started, it drives the driving screw connected thereto to rotate. After the driving screw rotates, it drives the multi-stage filter element to move vertically through the threaded port matched therewith. The driving screw drives each multi-stage filter element to move to different degrees through multiple sections, thereby realizing the adjustment and replacement of the multi-stage filter element. This is conducive to adjusting the multi-stage filter element when the filtering effect of the multi-stage filter element is insufficient, and to adjusting and replacing the multi-stage filter element when the filtering effect of the multi-stage filter element is weakened, thereby helping to improve the filtering effect of sewage.

[0030] The rubber gasket is adapted to the threaded port, and the gap between the threaded port and the driving screw is flexibly filled. The gap is filled by the deformation and extrusion of the rubber gasket, which helps to prevent sewage from leaking downward from the gap.

[0031] Preferably, the filter element deployment component further comprises:

[0032] A connecting pipe is fixedly connected between the filter box and the water outlet pipe, and the top connecting end of the connecting pipe is located between the instant filter element and the spare filter element;

[0033] The connecting pipe connects the filter box and the outlet pipe. When the sewage pollution level increases and the filtering efficiency of the multi-stage filter element is insufficient, the sewage enters the multi-stage filter element that is increased by adjustment. Then, when the multi-stage filter element is reset, there is still some water flow in the multi-stage filter element. At this time, the water flows downward, and the multi-stage filter element below is in a closed state and no water flows in. At this time, the water flows along the connecting pipe into the inside of the outlet pipe, so that the water can be fully discharged, which is conducive to avoiding the situation where sewage remains inside the multi-stage filter element.

[0034] Preferably, the drive screw comprises:

[0035] A rotating shaft, rotatably mounted on the inner bottom of the filter box;

[0036] A first threaded rod, rotatably sleeved on the outer ring of the rotating shaft;

[0037] a second threaded rod, fixedly mounted on the top of the rotating shaft;

[0038] a third threaded rod, rotatably mounted on the top of the second threaded rod;

[0039] A round rod is rotatably mounted on the top of the third threaded rod, and the top is fixedly mounted on the inner top of the filter box;

[0040] Two first latching mechanisms are respectively installed between the second threaded rod and the third threaded rod and between the third threaded rod and the round rod;

[0041] a second locking mechanism, installed between the rotating shaft and the first threaded rod;

[0042] The driving motor drives the rotating shaft to rotate. When the second locking mechanism is started, the rotating shaft rotates and drives the first threaded rod and the second threaded rod to rotate. At this time, the first threaded rod and the second threaded rod rotate to drive the spare filter element to move upward until the multi-stage filter element at the top of the spare filter element is completely moved to the position of the second threaded rod. At this time, the second locking mechanism cancels the locking position, so that the rotating shaft only drives the second threaded rod to rotate. After the second threaded rod rotates, it drives the multi-stage filter element at the top of the spare filter element to continue to move upward to the bottom of the instant filter element for supplementary filtration. After use, it can drive the multi-stage filter element to move downward and reset in the same way;

[0043] When the multi-stage filter element at the top of the spare filter element is completely moved to the position of the second threaded rod, the second locking mechanism cancels the locking, and the first locking mechanism starts the locking, so that the rotation of the shaft drives the second threaded rod, the third threaded rod and the round rod to rotate synchronously, thereby driving the multi-stage filter element at the top of the spare filter element and the instant filter element to move upward synchronously, so that the instant filter element moves upward to the inside of the top cover for storage, and the multi-stage filter element at the top of the spare filter element is moved and replaced by a new instant filter element, thereby realizing the adjustment increase and adjustment replacement of the multi-stage filter element.

[0044] Preferably, the first locking mechanism includes:

[0045] a first limiting block movably inserted at the top of the second threaded rod or the third threaded rod;

[0046] a first magnet, fixed to the bottom of the first limiting block;

[0047] a first electromagnet fixed inside the second threaded rod or the third threaded rod;

[0048] A first limiting groove is provided at the bottom of the third threaded rod or the round rod, and the first limiting groove is plug-fitted with the first limiting block;

[0049] a battery fixed inside the second threaded rod or the third threaded rod;

[0050] The first electromagnet is activated after being energized, so that the first electromagnet and the first magnet have the same magnetic poles facing each other, thereby pushing the first magnet upward through magnetic repulsion, and the first magnet drives the first limit block to move upward, so that the first limit block is inserted into the interior of the first limit groove, thereby achieving locking;

[0051] After the first electromagnet is energized in the reverse direction, the first electromagnet and the first magnet have opposite magnetic poles, so that the first magnet is pulled downward by magnetic attraction, thereby driving the first limit block to move downward and reset.

[0052] Preferably, the second locking mechanism includes:

[0053] A mounting groove is provided on the inner top of the rotating shaft;

[0054] Two second limit blocks are symmetrically slidably installed inside the installation slot;

[0055] Two second limiting grooves are symmetrically formed on the inner wall of the first threaded rod, and the second limiting grooves are plugged and adapted to the second limiting block;

[0056] Two inclined surfaces are symmetrically arranged on opposite sides of the two second limiting blocks;

[0057] a plurality of springs, fixed between the two second limiting blocks;

[0058] a slide groove, formed at the bottom of the second threaded rod;

[0059] A push rod is slidably inserted into the interior of the sliding groove;

[0060] a second magnet fixed to the top of the push rod;

[0061] a second electromagnet fixed to the top of the chute;

[0062] When the second electromagnet is energized, it generates a magnetic repulsive force with the second magnet to push the second magnet downward, and the second magnet drives the push rod to move downward. After the push rod moves downward, it pushes the two inclined surfaces to push the two second limit blocks to move in opposite directions, thereby pushing the second limit blocks to insert into the interior of the second limit groove to achieve locking;

[0063] When the second electromagnet is energized in the reverse direction, it generates magnetic attraction with the second magnet to push the second magnet to move upward and reset, thereby driving the push rod to move upward and reset. At this time, the two second limit blocks are reset under the pulling action of the spring, thereby canceling the blocking effect.

[0064] Preferably, the multi-stage filter element comprises:

[0065] An inner tank is provided at the bottom of the multi-stage filter element;

[0066] The first bottom plate is in the shape of an elongated strip and is fixed to the bottom of the inner tank;

[0067] A filter material is fixed inside the inner tank;

[0068] A circular groove is formed through the top of the multi-stage filter element;

[0069] A sealing plug is inserted into the circular groove;

[0070] a straight rod, fixed to the bottom of the sealing plug, passing through the filter material and the multi-stage filter element;

[0071] a rubber block, fixed to the bottom of the rubber block;

[0072] a first rubber groove, fixed to the top of the multi-stage filter element;

[0073] When the multi-stage filter element moves upward, the multi-stage filter element below is not driven upward, so that the two multi-stage filter elements move relative to each other. At this time, the first rubber groove pulls the rubber block, thereby pulling the straight rod downward. The straight rod pulls the sealing plug downward, so that the sealing plug is separated from the circular groove, so that the water flow can pass through the circular groove into the interior of the inner groove, and then is filtered by the filter material and then discharged along the two sides of the first bottom plate. Then the multi-stage filter element is driven upward again, so that the rubber block is separated from the rubber block.

[0074] When the multi-stage filter element is driven to reset, the multi-stage filter element moves downward, causing the rubber block to rest against the first rubber groove, and then the rubber block is pushed upward under the extrusion action. The rubber block pushes the straight rod upward, and the straight rod pushes the sealing plug upward to be inserted into the inside of the circular groove to achieve sealing. When the multi-stage filter element continues to move downward, the rubber block is squeezed and inserted into the inside of the first rubber groove, thereby restoring the initial state of the multi-stage filter element.

[0075] Preferably, the filter element deployment component further comprises:

[0076] a second bottom plate, slidably mounted inside the filter box and adapted to fit the drive screw;

[0077] a second rubber groove, provided on the top of the second bottom plate;

[0078] When the bottom multi-stage filter element is moved upward for adjustment, addition or replacement, the second rubber groove on the top of the second bottom plate can pull and push the rubber block, thereby helping to avoid the situation where the bottom multi-stage filter element cannot be used smoothly.

[0079] Compared with the prior art, the present invention has the following beneficial effects:

[0080] The present invention automatically replaces the multi-stage filter element through the arrangement of the water quality detection component and the filter element deployment component, which is beneficial for automatically replacing the multi-stage filter element when the filtering effect of the multi-stage filter element is weakened after long-term use, thereby facilitating the maintenance of the filtering effect on sewage.

DETAILED DESCRIPTION

[0088] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0089] like Figures 1 to 6 The water treatment device with a self-checking function shown includes a filter box 1 and further includes:

[0090] The water inlet pipe 101 is fixedly connected to the top of one side of the filter box 1;

[0091] The water outlet pipe 102 is fixedly connected to the bottom of the other side of the filter box 1;

[0092] The top cover 103 is detachably fixed to the top of the filter box 1;

[0093] Multiple multi-stage filter cores 104 are installed inside the filter box 1. The multi-stage filter core 104 located between the water inlet pipe 101 and the water outlet pipe 102 is called an immediate filter core, and the multi-stage filter core 104 located at the bottom of the immediate filter core is called a spare filter core. The water inside the filter box 1 flows through the immediate filter core for filtration.

[0094] Two water quality detection components are installed inside the water inlet pipe 101 and the water outlet pipe 102 respectively, for detecting the water quality of the incoming and outgoing water flows respectively;

[0095] The filter element deployment component is installed inside the filter box 1 and is used to dynamically deploy the multi-stage filter element 104 to enhance the filtering effect when poor discharge water quality is detected;

[0096] During the sewage treatment process, due to the different pollution levels of the input sewage, when the sewage is transported to the water treatment device for treatment, if the treatment capacity of the water treatment device remains unchanged and the sewage pollution level increases, the water quality of the treated sewage may not meet the requirements. At the same time, as the sewage treatment volume increases, the treatment effect of the water treatment device weakens, which may also cause the water quality of the treated sewage to not meet the requirements.

[0097] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: sewage enters the interior of the filter box 1 along the water inlet pipe 101, then passes through the instant filter element inside the filter box 1, and then the filtered water is discharged along the water outlet pipe 102, thereby achieving filtration of the sewage;

[0098] The water quality detection components inside the water inlet pipe 101 and the water outlet pipe 102 detect the water quality of the incoming sewage and the water quality of the discharged water respectively;

[0099] When the water quality detection component detects that the water quality of the discharged water does not meet the requirements, the water quality detection component is started to detect the water quality of the incoming sewage. If it is detected that the pollution level of the incoming sewage has increased, it means that the pollution level of the sewage has increased, resulting in the water quality of the treated sewage not meeting the requirements. At this time, the filter element deployment component is started, and the filter element deployment component drives the multi-stage filter element 104 at the top of the spare filter element to move upward, so that the multi-stage filter element 104 at the top of the spare filter element moves to the bottom of the instant filter element. At this time, the sewage is filtered by the instant filter element and then passes through the moved multi-stage filter element 104 for a second filtration, thereby increasing the filtration of the sewage, so that the sewage with an increased pollution level can be filtered again, so that the filtered sewage meets the requirements;

[0100] If it is detected that the pollution level of the incoming sewage remains unchanged or weakened, it means that the filtering effect of the instant filter element has weakened after long-term use. At this time, the filter element deployment component is started, and the filter element deployment component drives the spare filter element and the instant filter element to move at the same time, so that the instant filter element moves upward to the inside of the top cover 103 for storage, and the multi-stage filter element 104 at the top of the spare filter element moves to the position between the water inlet pipe 101 and the water outlet pipe 102 to be called a new instant filter element, thereby automatically replacing the multi-stage filter element 104, which is beneficial for automatically replacing the multi-stage filter element 104 when the filtering effect of the multi-stage filter element 104 is weakened after long-term use, thereby helping to maintain the filtering effect on sewage.

[0101] As an optional embodiment, the water quality detection component includes:

[0102] The detection box 2 is fixedly connected to the middle of the water inlet pipe 101 or the water outlet pipe 102;

[0103] The water quality detector 201 is fixedly mounted on the inner wall of the detection box 2 and is used to detect the water quality;

[0104] When sewage or filtered water flows through the interior of the detection box 2, the water quality detector 201 can detect the passing water, thereby being able to perform a self-inspection on the water quality of the filtered water in real time and to detect the incoming sewage.

[0105] As an optional embodiment, the water quality detection component further includes:

[0106] The stirring blade 3 is rotatably installed inside the detection box 2;

[0107] The stirring motor 301 is fixed to the outer wall of the detection box 2. The output shaft of the stirring motor 301 passes through the side wall of the detection box 2 and drives the stirring blade 3 to rotate.

[0108] After the stirring motor 301 is started, the stirring blade 3 connected to it is driven to rotate through the output shaft. After the stirring blade 3 rotates, it can stir the passing sewage or water flow, so that the water flow is uniform under the stirring action, which is helpful to avoid local water quality not meeting the standards or the local water quality pollution level being aggravated, and the water quality detector 201 fails to detect it, resulting in a situation that affects the judgment result.

[0109] As an optional embodiment, the filter element deployment component includes:

[0110] The driving motor 4 is fixed to the bottom of the filter box 1;

[0111] Multiple threaded openings 401 are respectively opened in the middle of the multi-stage filter element 104;

[0112] The drive screw is rotatably installed inside the filter box 1. The output shaft of the drive motor 4 passes through the bottom of the filter box 1 and drives the drive screw to rotate. The drive screw is threadedly adapted to the threaded openings 401 through multiple segments to drive the multi-stage filter element 104 to move vertically.

[0113] A plurality of rubber gaskets 402 are fixed to the middle of each threaded opening 401 to flexibly fill the gap between the threaded opening 401 and the drive screw;

[0114] After the drive motor 4 is started, it drives the drive screw connected thereto to rotate. After the drive screw rotates, it drives the multi-stage filter element 104 to move vertically through the threaded opening 401 matched therewith. The drive screw drives each multi-stage filter element 104 to move to different degrees through multiple segments, thereby realizing the adjustment and replacement of the multi-stage filter element 104. This is conducive to adjusting the multi-stage filter element 104 when the filtering effect of the multi-stage filter element 104 is insufficient, and to adjusting and replacing the multi-stage filter element 104 when the filtering effect of the multi-stage filter element 104 is weakened, thereby facilitating the improvement of the filtering effect of the sewage.

[0115] The rubber gasket 402 is adapted to the threaded opening 401 to flexibly fill the gap between the threaded opening 401 and the driving screw. The gap is filled by the deformation and extrusion of the rubber gasket 402, which helps to prevent sewage from leaking downward from the gap.

[0116] As an optional embodiment, the filter element deployment component further includes:

[0117] The connecting pipe 5 is fixedly connected between the filter box 1 and the water outlet pipe 102, and the top connecting end of the connecting pipe 5 is located between the instant filter element and the spare filter element;

[0118] The connecting pipe 5 connects the filter box 1 and the outlet pipe 102. When the sewage pollution level increases and the filtering efficiency of the multi-stage filter element 104 is insufficient, the sewage enters the multi-stage filter element 104 that is increased by adjustment. Then, when the multi-stage filter element 104 is reset, there is still some water flow in the multi-stage filter element 104. At this time, the water flows downward, and the multi-stage filter element 104 below is in a closed state and no water flows in. At this time, the water flows along the connecting pipe 5 into the inside of the outlet pipe 102, so that the water can be fully discharged, which is conducive to avoiding the situation where sewage remains inside the multi-stage filter element 104.

[0119] As an optional embodiment, the drive screw includes:

[0120] The rotating shaft 6 is rotatably mounted on the inner bottom of the filter box 1;

[0121] The first threaded rod 601 is rotatably sleeved on the outer ring of the rotating shaft 6;

[0122] The second threaded rod 602 is fixedly mounted on the top of the rotating shaft 6;

[0123] The third threaded rod 603 is rotatably mounted on the top of the second threaded rod 602;

[0124] The round rod 604 is rotatably mounted on the top of the third threaded rod 603, and the top is fixedly mounted on the inner top of the filter box 1;

[0125] Two first locking mechanisms are installed between the second threaded rod 602 and the third threaded rod 603 and between the third threaded rod 603 and the round rod 604 respectively;

[0126] The second locking mechanism is installed between the rotating shaft 6 and the first threaded rod 601;

[0127] The driving motor 4 drives the rotating shaft 6 to rotate. When the second locking mechanism is started, the rotating shaft 6 rotates and drives the first threaded rod 601 and the second threaded rod 602 to rotate. At this time, the first threaded rod 601 and the second threaded rod 602 rotate to drive the spare filter element to move upward until the multi-stage filter element 104 at the top of the spare filter element is completely moved to the position of the second threaded rod 602. At this time, the second locking mechanism cancels the locking, and the upper first locking mechanism starts the locking, so that the rotating shaft 6 only drives the second threaded rod 602 to rotate. After the second threaded rod 602 rotates, it drives the multi-stage filter element 104 at the top of the spare filter element to continue to move upward to the bottom of the instant filter element for supplementary filtration. After use, it can similarly drive the multi-stage filter element 104 to move downward and reset;

[0128] When the multi-stage filter element 104 at the top of the spare filter element is completely moved to the position of the second threaded rod 602, the second locking mechanism cancels the locking, and the first locking mechanism below starts the locking, so that the rotating shaft 6 rotates to drive the second threaded rod 602 and the third threaded rod 603 to rotate synchronously, thereby driving the multi-stage filter element 104 at the top of the spare filter element and the instant filter element to move upward synchronously, so that the instant filter element moves upward to the inside of the top cover 103 for storage, and the multi-stage filter element 104 at the top of the spare filter element is moved and replaced by a new instant filter element, thereby realizing the adjustment increase and adjustment replacement of the multi-stage filter element 104.

[0129] As an optional embodiment, the first locking mechanism includes:

[0130] A first limiting block 7 is movably inserted at the top of the second threaded rod 602 or the third threaded rod 603;

[0131] The first magnet 701 is fixed to the bottom of the first limiting block 7;

[0132] The first electromagnet 702 is fixed inside the second threaded rod 602 or the third threaded rod 603;

[0133] The first limiting groove 703 is provided at the bottom of the third threaded rod 603 or the round rod 604, and the first limiting groove 703 is plugged and adapted to the first limiting block 7;

[0134] The battery 704 is fixed inside the second threaded rod 602 or the third threaded rod 603;

[0135] After the first electromagnet 702 is powered on, it starts up, so that the same magnetic poles of the first electromagnet 702 and the first magnet 701 face each other, thereby pushing the first magnet 701 upward through magnetic repulsion. The first magnet 701 drives the first limiting block 7 to move upward, so that the first limiting block 7 is inserted into the first limiting groove 703, thereby achieving locking.

[0136] After the first electromagnet 702 is energized in the reverse direction, the first electromagnet 702 and the first magnet 701 have opposite magnetic poles, thereby pulling the first magnet 701 downward through magnetic attraction, thereby driving the first limit block 7 to move downward and reset.

[0137] As an optional embodiment, the second locking mechanism includes:

[0138] The mounting groove 808 is provided at the inner top of the rotating shaft 6;

[0139] Two second limiting blocks 8 are symmetrically slidably installed inside the installation groove 808;

[0140] Two second limiting grooves 801 are symmetrically provided on the inner wall of the first threaded rod 601 , and the second limiting grooves 801 are plugged and adapted to the second limiting block 8 ;

[0141] Two inclined surfaces 802 are symmetrically arranged on opposite sides of the two second limiting blocks 8;

[0142] A plurality of springs 803 are fixed between the two second limiting blocks 8;

[0143] A chute 807 is provided at the bottom of the second threaded rod 602;

[0144] The push rod 804 is slidably inserted into the inner portion of the sliding groove 807;

[0145] The second magnet 805 is fixed to the top of the push rod 804;

[0146] The second electromagnet 806 is fixed to the top of the slide 807;

[0147] When the second electromagnet 806 is energized, it generates a magnetic repulsive force with the second magnet 805, pushing the second magnet 805 downward. The second magnet 805 drives the push rod 804 downward. After the push rod 804 moves downward, it pushes the two inclined surfaces 802 to push the two second limiting blocks 8 to move in opposite directions, thereby pushing the second limiting blocks 8 to insert into the second limiting groove 801 to achieve locking.

[0148] When the second electromagnet 806 is reversely energized, it generates a magnetic attraction with the second magnet 805 to push the second magnet 805 to move upward and reset, thereby driving the push rod 804 to move upward and reset. At this time, the two second limit blocks 8 are reset under the pulling action of the spring 803, thereby canceling the locking effect.

[0149] As an optional embodiment, the multi-stage filter element 104 includes:

[0150] The inner tank 906 is provided at the bottom of the multi-stage filter element 104;

[0151] The first bottom plate 907 is in the shape of an elongated strip and is fixed to the bottom of the inner tank 906;

[0152] Filter material 905 is fixed inside the inner tank 906;

[0153] The circular groove 901 is formed through the top of the multi-stage filter element 104;

[0154] The sealing plug 9 is inserted into the circular groove 901;

[0155] The straight rod 902 is fixed to the bottom of the sealing plug 9 and passes through the filter material 905 and the multi-stage filter element 104;

[0156] The rubber block 903 is fixed to the bottom of the rubber block 903;

[0157] The first rubber groove 904 is fixed to the top of the multi-stage filter element 104;

[0158] When the multi-stage filter element 104 moves upward, the multi-stage filter element 104 below is not driven upward, so that the two multi-stage filter elements 104 move relative to each other. At this time, the first rubber groove 904 pulls the rubber block 903, thereby pulling the straight rod 902 downward. The straight rod 902 pulls the sealing plug 9 downward, so that the sealing plug 9 is separated from the circular groove 901, so that the water flow can pass through the circular groove 901 into the interior of the inner groove 906, and then pass through the filter material 905 to be filtered, and then discharged along the two sides of the first bottom plate 907. Then the multi-stage filter element 104 is driven upward again, so that the rubber block 903 is separated from the rubber block 903;

[0159] When the multi-stage filter element 104 is driven to reset, the multi-stage filter element 104 moves downward, causing the rubber block 903 to rest against the first rubber groove 904, and then the rubber block 903 is pushed upward under the extrusion action. The rubber block 903 pushes the straight rod 902 to move upward, and the straight rod 902 pushes the sealing plug 9 to move upward and insert into the interior of the circular groove 901 to achieve sealing. When the multi-stage filter element 104 continues to move downward, the rubber block 903 is squeezed and inserted into the interior of the first rubber groove 904, thereby restoring the initial state of the multi-stage filter element 104.

[0160] As an optional embodiment, the filter element deployment component further includes:

[0161] The second bottom plate 10 is slidably mounted inside the filter box 1 and is adapted to the driving screw;

[0162] The second rubber groove 1001 is provided on the top of the second bottom plate 10;

[0163] When the multi-stage filter element 104 at the bottom is moved upward for adjustment, addition or replacement, the second rubber groove 1001 at the top of the second base plate 10 can pull and push the rubber block 903, thereby helping to avoid the situation where the multi-stage filter element 104 at the bottom cannot be used smoothly.

[0164] The working principle of the present invention is as follows: sewage enters the interior of the filter box 1 along the water inlet pipe 101, then passes through the instant filter element inside the filter box 1, and then the filtered water flow is discharged along the water outlet pipe 102, thereby achieving the filtration of the sewage;

[0165] The water quality detection components inside the water inlet pipe 101 and the water outlet pipe 102 detect the water quality of the incoming sewage and the water quality of the discharged water respectively;

[0166] When the water quality detection component detects that the water quality of the discharged water does not meet the requirements, the water quality detection component is started to detect the water quality of the incoming sewage. If it is detected that the pollution level of the incoming sewage has increased, it means that the pollution level of the sewage has increased, resulting in the water quality of the treated sewage not meeting the requirements. At this time, the filter element deployment component is started, and the filter element deployment component drives the multi-stage filter element 104 at the top of the spare filter element to move upward, so that the multi-stage filter element 104 at the top of the spare filter element moves to the bottom of the instant filter element. At this time, the sewage is filtered by the instant filter element and then passes through the moved multi-stage filter element 104 for a second filtration, thereby increasing the filtration of the sewage, so that the sewage with an increased pollution level can be filtered again, so that the filtered sewage meets the requirements;

[0167] If it is detected that the pollution level of the incoming sewage remains unchanged or weakened, it means that the filtering effect of the instant filter element has weakened after long-term use. At this time, the filter element deployment component is started, and the filter element deployment component drives the spare filter element and the instant filter element to move at the same time, so that the instant filter element moves upward to the inside of the top cover 103 for storage, and the multi-stage filter element 104 at the top of the spare filter element moves to the position between the water inlet pipe 101 and the water outlet pipe 102 to be called a new instant filter element, thereby automatically replacing the multi-stage filter element 104, which is beneficial for automatically replacing the multi-stage filter element 104 when the filtering effect of the multi-stage filter element 104 is weakened after long-term use, thereby helping to maintain the filtering effect on sewage.
