[0031] The device can efficiently collect, dry and recycle flocculation in wastewater through the transmission assembly 2 and the drying and recycling assembly 3. Firstly, the design of the rotating blade 41 and the poking bar 42 in the device not only prevents flocculation from adhering to the inner wall of the blocking net 4, but also disperses large flocculation according to the needs, increases the surface area, and thus speeds up the air-drying speed and improves the drying efficiency. Secondly, the detachable design of the mounting block 22 and the connecting block 23 on the transmission belt 21 makes the device flexible and adaptable to different processing needs, significantly improving the efficiency and effect of wastewater treatment. Through the cooperation of the electromagnet 27 and the tension bar 25, the precise control of the blocking net 4 and the abutting net 5 is realized, ensuring that the flocculation can be effectively blocked and clamped. The air blowing system in the drying and recycling pipeline 31 and the electric clamping jaw further enhance the drying and recycling effect of the flocculation. The design of the moving sealing plate 34 and the elastic cloth 35 ensures the sealing of the system during operation, preventing secondary pollution. Not only does it solve the problems of flocculation blockage and low filtration efficiency, but also simplifies the maintenance process, reduces the operating cost, and improves the stability and economy of the overall operation.

[0032] The connecting block 23 is fixedly connected to the bottom end of the mounting block 22, and a pair of symmetrical control grooves 24 are formed in the connecting block 23. A plurality of uniformly distributed tension bars 25 are fixedly connected in the control grooves 24, and an abutting block 26 is slidably connected in the control grooves 24. The tension bars 25 are connected to the abutting block 26.

[0033] The electromagnet 27 is embedded in the connecting block 23, and the abutting block 26 is composed of a magnetic block and a friction pad. The friction pad is installed around the magnetic block.

[0034] The U-shaped block 28 is fixedly connected to the top end of the blocking net 4 and the abutting net 5, and is slidably connected to the connecting block 23. A pair of symmetrical fixed grooves 29 are formed in the inner wall of the U-shaped block 28, and are matched with the abutting block 26.

[0035] In the structure of the device, the bottom end of the mounting block 22 is fixedly connected to the connecting block 23. A pair of symmetrical control grooves 24 are formed in the connecting block 23, and a plurality of uniformly distributed tension bars 25 are fixedly connected in the control grooves 24. The control grooves 24 also slidably connect the abutting block 26. The tension bars 25 are connected to the abutting block 26, so that the abutting block 26 can be pulled and limited in movement.

[0036] The top end of the blocking net 4 and the abutting net 5 are fixedly connected with U-shaped blocks 28, which are slidingly connected with the connecting block 23, and a pair of symmetrical fixed grooves 29 are formed in the inner wall of the U-shaped blocks, which are matched with the abutting blocks 26. The connecting block 23 is inlaid with an electromagnet 27, and the abutting block 26 is composed of a magnetic block and a friction pad, wherein the friction pad is installed at the outer enclosure of the magnetic block, so that when the electromagnet is electrified, the abutting block 26 can be repelled into the fixed groove 29, thereby achieving the fixation of the blocking net 4 and the abutting net 5, and when the power is turned off, the abutting block 26 is pulled back to the control groove 24 by the tension strip 25, i.e. the restriction is disconnected.

[0037] The blocking net 4 is provided with a rotating vane 41 installed through a bearing, one end of the rotating vane 41 penetrates through the blocking net 4 and extends to the other end of the blocking net 4, and a pulling strip 42 is installed at the other end of the blocking net 4 and abuts against the inner wall of the blocking net 4.

[0038] The abutting net 5 is provided with a plurality of uniformly distributed elastic limiting rods, and the blocking net 4 is provided with a plurality of uniformly distributed abutting grooves matched with the plurality of elastic limiting rods.

[0039] The drying and recycling assembly 3 includes a pair of drying and recycling pipes 31, which are installed outside the transmission belt 21. The top end of the drying and recycling pipe 31 is provided with an electric push rod 32, and the output end of the electric push rod 32 is fixedly connected with a connecting frame 33.

[0040] The drying and recycling pipe 31 is slidingly connected with a moving sealing plate 34, which is fixedly connected with the connecting frame 33. The moving sealing plate 34 is provided with an elastic cloth 35 at the end away from the electric push rod 32, and the elastic cloth 35 is connected with the drying and recycling pipe 31.

[0041] The moving sealing plate 34 is provided with an elastic sealing pad at the end close to the transmission belt 21. The elastic sealing pad abuts against the surface of the transmission belt 21 during the operation of the transmission belt 21, thereby achieving a sealing structure. The material of the elastic sealing pad is any one of polyurethane and fluorine rubber.

[0042] The drying and recycling pipe 31 is provided with an electric clamping jaw, which is used to clamp the abutting net 5.

[0043] When the device is used for wastewater treatment, a plurality of mounting blocks 22 are installed on the transmission belt 21, and the blocking nets 4 and the abutting nets 5 are alternately distributed on the mounting blocks 22. When the transmission belt 21 rotates, the connecting blocks 23 on the mounting blocks 22 drive the blocking nets 4 into the flow-through pipe 1. When the blocking nets 4 come into contact with the elastic resistance friction pads on the inner wall of the flow-through pipe 1, the electromagnet 27 in the connecting block 23 is powered off, and under the action of the tension strip 25, the abutting block 26 slides into the control groove 24 from the fixed groove 29 of the U-shaped block 28, thereby releasing the restriction of the connecting block 23 on the U-shaped block 28, so that the blocking nets 4 abut against the elastic resistance friction pads on the inner wall of the flow-through pipe 1 and stay in the flow-through pipe 1, while the mounting blocks 22 and the connecting blocks 23 continue to move with the transmission belt 21.

[0044] Since the direction of the wastewater flow is consistent with the direction of the stirring strip 42 and the rotating blade 41, the blocking nets 4 can effectively block the flocculation in the wastewater, and at the same time, the wastewater acts on the rotating blade 41 to make it rotate, thereby driving the stirring strip 42 to rotate, preventing the flocculation from adhering to the inner wall of the blocking nets 4, maintaining the flow rate of the wastewater, and improving the collection efficiency of the flocculation.

[0045] The blocking nets 4 stay in the flow-through pipe 1 to block the flocculation. Since the blocking nets 4 and the abutting nets 5 are alternately arranged and maintain a certain distance therebetween, the abutting nets 5 continuously rotate to abut against the blocking nets 4, the elastic limiting rods on the abutting nets 5 are clamped into the abutting grooves on the blocking nets 4, and the blocking nets 4 are pushed to move out of the flow-through pipe 1. When the abutting nets 5 abut against the blocking nets 4, the flocculation is clamped therebetween.

[0046] During the clamping of the flocculation, the abutting nets 5 and the blocking nets 4 change from a vertical state to a horizontal state. The electric push rod 32 is started to drive the connecting frame 33 to move, thereby driving the moving sealing plate 34 to move, so as to ensure that the blocking nets 4 and the abutting nets 5 can move into the drying and recycling pipe 31. Subsequently, the electric push rod 32 is reset, the moving sealing plate 34 abuts against the transmission belt 21, and sealing is achieved through the elastic sealing pad at one end of the moving sealing plate 34.

[0047] The air blowing system in the drying and recycling pipeline 31 will dry the flocculation in the blocking net 4 and the abutting net 5. The power supply of the electromagnet 27 in the connecting block 23 corresponding to the abutting net 5 is turned off, and at the same time, the electrically operated clamping jaw in the drying and recycling pipeline 31 clamps the abutting net 5. Under the action of wind force, the rotating blade 41 rotates, driving the poking bar 42 to rotate, further enhancing the drying effect of the flocculation. The transmission belt 21 continues to run. After a period of air drying, when the blocking net 4 meets one of the mounting blocks 22 and the connecting block 23 again, the power supply of the electromagnet 27 is started to make it contact with the blocking net 4 and take away the blocking net 4, so that it restores from the horizontal state to the vertical state. The wind force takes away the dried flocculation on the blocking net 4, and most of the flocculation remains on the abutting net 5. After the blocking net 4 leaves the abutting net 5, the wind force recycles the dried flocculation. The moving sealing plate 34 ensures the normal passage of the abutting net 5 while maintaining the sealing property. The elastic cloth 35 stretches and contracts to ensure the sealing property, so that the dried flocculation is collected by the drying and recycling pipeline 31.

[0048] When collecting and air-drying the flocculation, the purpose of the rotating poking bar 42 on the blocking net 4 is to prevent the flocculation from adhering to the blocking net 4 and to speed up the air-drying effect of the flocculation. Whether the large flocculation should be broken up can be determined according to actual needs.

[0049] Breaking up the flocculation: The broken-up flocculation has a larger surface area, which can speed up the air-drying speed, and smaller flocculation can be more evenly dried by air, avoiding the problem of moisture inside large flocculation.

[0050] Not breaking up the flocculation: Not breaking up the flocculation can reduce the complexity of the system and the operation steps, and large flocculation can be more stably collected and processed, reducing the loss of fine particles.

[0051] If the subsequent processing of the flocculation requires it to remain in large blocks, not breaking up may be more appropriate; but if drying speed and efficiency are key factors, breaking up the flocculation is more advantageous. Therefore, the specific choice depends on the design goals and processing needs of the system.

[0052] Then, whether to break up only needs to consider the rotating resistance of the rotating blade 41 when designing, so as to decide whether to break up.

[0053] In addition, the number and distribution of the mounting blocks 22 and the connecting blocks 23 on the transmission belt 21 also affect the collection speed of the blocking net 4 and the abutting net 5. According to the actual situation, the number and distribution of the mounting blocks 22 and the connecting blocks 23 are designed, and the mounting blocks 22 and the connecting blocks 23 on the transmission belt 21 are designed to be detachable, so as to adjust the distribution of the mounting blocks 22 and the connecting blocks 23 according to actual needs, and further adjust the distance and distribution form between the blocking net 4 and the abutting net 5.

[0054] Working principle:

[0055] The floccus in the wastewater is collected, dried and recycled efficiently by the transmission assembly 2 and the drying and recycling assembly 3. A plurality of mounting blocks 22 are mounted on the transmission belt 21, and the blocking net 4 and the abutting net 5 are alternately distributed on the mounting blocks 22. When the transmission belt 21 rotates, the connecting block 23 on the mounting block 22 drives the blocking net 4 into the flow-through pipe 1. When the blocking net 4 contacts the elastic resistance friction pad on the inner wall of the flow-through pipe 1, the electromagnet 27 in the connecting block 23 is powered off, the tension strip 25 acts to make the abutting block 26 slide into the regulating groove 24 from the fixed groove 29 of the U-shaped block 28, the connecting block 23 is released from the restriction of the U-shaped block 28, the blocking net 4 abuts against the elastic resistance friction pad on the inner wall of the flow-through pipe 1 and stays in the flow-through pipe 1, and the mounting block 22 and the connecting block 23 continue to move with the transmission belt 21. The direction of the wastewater flow is consistent with the directions of the rotating blade 41 and the poking strip 42. The blocking net 4 effectively blocks the floccus in the wastewater, and the rotating blade 41 and the poking strip 42 are rotated to prevent the floccus from adhering to the inner wall of the blocking net 4, so as to maintain the flow rate of the wastewater and improve the collection efficiency of the floccus. The blocking net 4 and the abutting net 5 are alternately arranged, the abutting net 5 continuously rotates, the elastic limiting rod is clamped into the abutting groove of the blocking net 4, and the blocking net 4 is pushed to move out of the flow-through pipe 1. When the abutting net 5 reaches the abutting state with the blocking net 4, the floccus is clamped between the two. The electric push rod 32 is started to drive the connecting frame 33 and the moving sealing plate 34 to move, so as to ensure that the blocking net 4 and the abutting net 5 enter the drying and recycling pipe 31. The blowing system in the drying and recycling pipe 31 blows the floccus dry, the electric clamping jaw clamps the abutting net 5, the rotating blade 41 rotates to drive the poking strip 42, and the floccus is further dried. The transmission belt 21 continuously operates, the electromagnet 27 is restarted to establish contact with the blocking net 4, the blocking net 4 is taken away, the vertical state is restored, and the dry floccus is taken away by the wind. The moving sealing plate 34 keeps the sealing property, ensures the normal passage of the abutting net 5, the elastic cloth 35 stretches and contracts to ensure the sealing property, and the dry floccus is collected by the drying and recycling pipe 31.
