[0004] The above technical solution still has some problems during use. It uses airbags to protect the magnet to prevent the magnet from direct contact with metal materials. The airbag is in contact with wastewater. The general airbag material is easily corroded by wastewater and has a short service life. Therefore, the material requirements for the airbag are higher, which increases the cost of use. In addition, the airbag is stretchable, and fine impurities in the wastewater may adhere to the surface of the airbag, causing the airbag to be unable to shrink normally, thereby affecting the use effect.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1 like Figure 1-6 As shown, a carbon conversion wastewater treatment device according to an embodiment of the present invention comprises a wastewater treatment pool 1 and a support 2, wherein the support 2 is provided with a separation mechanism 3, a discharge mechanism 4 and a control mechanism 5, wherein the control mechanism 5 is used to control the separation mechanism 3 and the discharge mechanism 4; The separation mechanism 3 includes: a rotating rod 31 rotatably arranged on the bracket 2; a support plate 32 fixedly connected to the bottom end of the rotating rod 31, the support plate 32 is located above the wastewater treatment tank 1, and a plurality of mounting grooves 321 are provided on the support plate 32; a plurality of protective covers 33 movably inserted on the support plate 32, the bottom end of the protective cover 33 passes through the mounting groove 321 and extends into the wastewater treatment tank 1, the top of the protective cover 33 is open, and a baffle 331 is fixedly connected to the top of the protective cover 33; a plurality of magnetic bars 34 movably inserted into the inside of the protective cover 33; The discharge mechanism 4 includes a collecting frame 41 disposed on the bracket 2 . The collecting frame 41 is located outside the supporting plate 32 . The inner side of the collecting frame 41 is open.

[0024] Specifically, a water inlet and a water outlet are respectively provided at the left and right ends of the wastewater treatment pool 1. According to different treatment process requirements, a feeding port for adding treatment agents can also be set at the inlet position on the left side of the wastewater treatment pool 1. Activated carbon and a filter component are installed in the wastewater treatment pool 1. The activated carbon is used to remove odors in the wastewater, and the filter component is used to filter impurities in the wastewater. The protective cover 33 is used to prevent the magnetic rod 34 from directly contacting the wastewater, thereby protecting the magnetic rod 34. The protective cover 33 is made of wear-resistant plastic and other materials, which does not affect the magnetic rod 34's ability to adsorb metals in the wastewater, and at the same time protects the magnetic rod 34; the protective cover 33 can move up and down relative to the support plate 32, and the magnetic rod 34 can move up and down relative to the protective cover 33. The protective cover 33 is inserted into the mounting groove 321, and the aperture of the mounting groove 321 is larger than the outer diameter of the protective cover 33. When the protective cover 33 is lifted upward, the metal attached to the outside of the protective cover 33 does not contact the inner wall of the mounting groove 321; the collecting frame 41 is surrounded by the outside of the supporting plate 32, and the height of the collecting frame 41 can be selected according to the situation. A discharge pipe is provided at the bottom of the collecting frame 41. After opening the discharge pipe, the metal collected inside the collecting frame 41 can be taken out.

[0025] In the carbon conversion wastewater treatment system, it is necessary to recycle the metal impurities in the wastewater. When the device is in use, the wastewater is sent into the wastewater treatment pool 1, and the wastewater flows from left to right. The bottom end of the protective cover 33 is inserted into the wastewater, and the rotating rod 31 is started to rotate, and the protective cover 33 rotates accordingly, stirring the wastewater, which can improve the fluidity of the wastewater. The magnetic field generated by the magnetic rod 34 can more fully contact the metal in the wastewater, thereby improving the adsorption effect of the metal in the wastewater. In addition, when the treatment agent is added to the wastewater, the stirring protective cover 33 can also accelerate the reaction between the agent and the wastewater; During the rotation of the support disk 32, the metal attached to the outside of the protective cover 33 has a tendency to be thrown outward to the inside of the collection frame 41 under the action of centrifugal force. After working for a period of time, a large amount of metal is adsorbed on the outside of the protective cover 33. In order to ensure that the magnetic bar 34 can normally adsorb and separate the metals in the wastewater, it is necessary to clean the metals attached to the outside of the protective cover 33. At this time, the support disk 32 does not stop rotating. The protective cover 33 is first lifted up until the protective cover 33 moves to the top of the support disk 32, and then the magnetic bar 34 is pulled upward from the protective cover 33. The baffle 331 prevents the metal on the outside of the protective cover 33 from being adsorbed and separated. As the magnetic bar 34 moves upward, after the magnetic bar 34 is separated from the protective cover 33, the magnetic bar 34 loses its suction force, and the metal originally adsorbed on the outside of the protective cover 33 is thrown outward under the action of centrifugal force and falls into the collection frame 41, thus realizing the function of separating and separately collecting the metals in the wastewater, and there is no need to stop the machine for cleaning, which improves the work efficiency. Compared with the traditional method of scraping and cleaning the magnetic bar 34, the device uses centrifugal force to automatically clean the metal, and the magnetic bar 34 does not directly contact the wastewater and metal substances, which improves the situation that the magnetic bar 34 is easily damaged by corrosion and scratching, and prolongs the service life of the magnetic bar 34. Compared with the elastic airbag and other solutions, the corrosion-resistant plastic protective cover 33 is used to protect the magnetic bar 34, and the shape of the protective cover 33 is fixed, the structure is simpler, the service life is longer, and cleaning and replacement are more convenient.

[0026] like Figure 3-7 As shown, the discharge mechanism 4 also includes a number of material guide members movably arranged on the support plate 32, and the material guide members include: a rotating shaft 42 rotatably arranged on the support plate 32; a guide plate 43 fixedly connected to the rotating shaft 42, the guide plate 43 is inclined, the bottom end of the guide plate 43 is open, and the size of the guide plate 43 is larger than the size of the mounting groove 321; after the metal on the protective cover 33 falls onto the guide plate 43, it slides along the guide plate 43 into the collection frame 41.

[0027] Specifically, when cleaning the metal outside the protective cover 33 , the thrown metal may fall onto the support plate 32 . In order to prevent the metal from passing through the installation groove 321 and falling back into the wastewater treatment tank 1 , a material guide is provided on the support plate 32 .

[0028] Initially, the guide plate 43 rotates to be offset from the mounting groove 321 to avoid interference with the up and down movement of the protective cover 33. When cleaning metal, after the protective cover 33 moves to the top of the support plate 32, the guide plate 43 is rotated to the bottom of the protective cover 33 and covers the mounting groove 321 to prevent the metal from falling back into the wastewater through the mounting groove 321. Under the action of centrifugal force, the impurities falling on the guide piece slide outward into the collection frame 41. Regardless of whether the metal falls into the guide piece, the metal will eventually move outward into the collection frame 41. Figure 7 What is shown is a comparison diagram of the changes in the matching status between the leftmost protection cover 33 and the guide plate 43 in the support plate 32.

[0029] like Figure 3-6 As shown, the separation mechanism 3 further includes: a positioning hole 35 provided at the top end of the support plate 32 ; and a positioning member 36 fixedly connected to the bottom end of the baffle 331 , wherein the positioning member 36 is inserted into the positioning hole 35 .

[0030] Specifically, the positioning member 36 is preferably but not limited to a telescopic rod 67 structure. After the protective cover 33 moves downward, the positioning member 36 is inserted into the positioning hole 35, so that the protective cover 33 and the support plate 32 maintain a relatively fixed position, thereby preventing the protective cover 33 from rocking back and forth inside the mounting groove 321; after the protective cover 33 moves upward, the positioning member 36 also moves to the top of the guide plate 43 so that the guide plate 43 can rotate smoothly under the protective cover 33.

[0031] like Figure 3-6 As shown, a convex plate 341 is fixed to the top of the magnetic rod 34, and the baffle 331 is blocked below the convex plate 341. The control mechanism 5 includes: a driving rod 51 arranged on the bracket 2, and the driving rod 51 is used to drive the magnetic rod 34 to rise and fall; and a supporting spring 52 arranged on the supporting plate 32 for pushing the protective cover 33 to move upward.

[0032] Specifically, a notch corresponding to the support spring 52 is provided in the guide plate 43, and the guide plate 43 never contacts the support spring 52. The drive rod 51 can adopt a hydraulic telescopic rod 67 or an electric telescopic rod 67. The bracket 2 is provided with a drive system for driving the drive rod 51 to move up and down. The upper and lower ends of the support spring 52 are respectively connected to the baffle 331 and the support plate 32.

[0033] The initial state is Figure 2As shown, at this time, the driving rod 51 moves downward and the supporting spring 52 is in a compressed state. When cleaning metal, the driving rod 51 is started to move upward, and the driving rod 51 drives the magnetic bar 34 to move upward. At the same time, the supporting spring 52 pushes the protective cover 33 to move upward until the protective cover 33 moves to the top of the supporting plate 32; when the driving rod 51 moves downward, it first drives the magnetic bar 34 to move downward and insert into the protective cover 33, and then the driving rod 51 continues to move downward, driving the protective cover 33 to move downward together through the convex plate 341.

[0034] like Figure 3-6 As shown, the control mechanism 5 also includes: a card plate 53 slidably arranged on the baffle 331, the top of the card plate 53 is provided with a slope corresponding to the convex plate 341, and after the card plate 53 moves down, the card plate 53 is pushed to move by the slope; a pushing spring 531 arranged on the baffle 331 for pushing the card plate 53 to block above the convex plate 341; a limit member 54 fixedly connected to the rotating rod 31, the limit member 54 is used to prevent the protective cover 33 from moving up, and the bottom end of the limit member 54 is provided with a beveled edge for pushing the card plate 53 away from the convex plate 341, and the card plate 53 is provided with a through groove corresponding to the beveled edge.

[0035] Specifically, the clamping plate 53 can slide horizontally on the baffle 331 , a sliding seat is fixed to the top of the baffle 331 , and the clamping plate 53 is slidably installed in the sliding seat, and both ends of the push spring 531 are respectively connected to the sliding seat and the clamping plate 53 .

[0036] Initially, the card plate 53 blocks the top of the convex plate 341, so that the magnetic rod 34 is fixed inside the protective cover 33. After the driving rod 51 moves up, it drives the protective cover 33 and the magnetic rod 34 to move up together; after the protective cover 33 moves up, the bottom end of the limit member 54 passes through the through slot and contacts the baffle 331 on the protective cover 33, so that the protective cover 33 stops moving up, and the bevel pushes the card plate 53 to separate from the convex plate 341. Without the obstruction of the card plate 53, the driving rod 51 continues to move up and drives the magnetic rod 34 to move up alone, so that the magnetic rod 34 and the protective cover 33 are separated up and down.

[0037] After the driving rod 51 drives the magnetic bar 34 to move downward, the protruding plate 341 contacts the slope on the card plate 53 and pushes the card plate 53 to move, so that the protruding plate 341 can move below the baffle 331, and then the driving rod 51 drives the magnetic bar 34 and the protective cover 33 to move downward together, and the entire device returns to its initial state.

[0038] It should be noted that after the bottom end of the limit member 54 is against the baffle 331, the friction between the two can keep the protective cover 33 and the support plate 32 in a fixed relative position in the horizontal direction. In order to further improve the position stability between the protective cover 33 and the support plate 32 after moving up, a snap-in groove corresponding to the bottom end of the limit member 54 can also be set on the top of the baffle 331.

[0039] like Figure 4-7 As shown, the control mechanism 5 further includes: a reset torsion spring arranged on the rotating shaft 42 ; and a magnetic block 55 arranged on the guide plate 43 , wherein the magnetic block 55 repels the magnetic bar 34 .

[0040] Specifically, the reset torsion spring is used to drive the guide plate 43 to rotate to the top of the mounting groove 321; initially, the protective cover 33 is inserted in the mounting groove 321, and the magnetic bar 34 is located inside the protective cover 33, and the repulsive force between the magnetic bar 34 and the magnetic block 55 drives the rotating shaft 42 to rotate, so that the material guide and the protective cover 33 are offset; after the protective cover 33 and the magnetic bar 34 move up, the magnetic bar 34 and the magnetic block 55 are offset up and down, and the reset torsion spring drives the rotating shaft 42 to rotate, so that the guide plate 43 rotates to the bottom of the protective cover 33.

[0041] Embodiment 2 like Figure 3-11 As shown, compared with Example 1, another implementation of the present invention is: a plurality of the protective covers 33 are evenly distributed in a ring, the number of the protective covers 33 is an even number, and also includes a switching mechanism 6, the switching mechanism 6 includes: a fixed plate 61 fixedly connected to the bottom end of the driving rod 51; a swivel 62 rotatably arranged at the bottom end of the fixed plate 61; a socket 63 fixedly connected to the top of the convex plate 341; a plurality of clamping blocks 64 fixedly connected to the bottom end of the swivel 62, the clamping block 64 is located between two adjacent clamping seats 63, and after the swivel 62 rotates back and forth, the clamping blocks 64 are respectively inserted into different clamping seats 63.

[0042] Specifically, the fixed plate 61 can move up and down, and the rotating ring 62 can rotate in the horizontal direction relative to the fixed plate 61; take the four magnetic bars 34 set on the support plate 32 as an example for explanation. Initially, the clamping block 64 at the bottom end of the rotating ring 62 is clamped with the clamping seat 63 above the left and right magnetic bars 34. After the fixed plate 61 moves up, it drives the left and right groups of magnetic bars 34 and the protective cover 33 to move up to perform metal cleaning. During this process, the front and rear magnetic bars 34 and the protective cover 33 do not move up, and the wastewater is continued to be stirred and the metal is separated from the wastewater, thereby ensuring the normal operation of the wastewater treatment work.

[0043] When the metal on the outside of the left and right protective covers 33 is cleaned, the left and right protective covers 33 and the magnetic rods 34 are moved down and reset to continue the wastewater treatment work, and the rotating ring 62 is rotated so that the clamping block 64 at the bottom of the rotating ring 62 is separated from the clamping seat 63 above the left and right magnetic rods 34, and is clamped with the clamping seat 63 on the front and rear magnetic rods 34. After the fixed plate 61 moves up, the front and rear magnetic rods 34 and the protective covers 33 are driven to move up to carry out the metal cleaning work; in this way, the function of not delaying the metal cleaning work and the wastewater treatment work is achieved. By setting the protective covers 33 to an even number evenly distributed in a ring, only half of the protective covers 33 are cleaned at a time, and the overall center of gravity of the other half of the protective covers 33 still remains coaxial with the rotating rod 31, thereby improving the problem of unstable rotation of the support plate 32 caused by the deviation of the overall center of gravity of the protective covers 33.

[0044] like Figure 8-9 As shown, the switching mechanism 6 also includes: two driven rods 65 movably inserted on the inner wall of the rotating ring 62; a shift plate 66 fixedly connected to the support plate 32, and the front and rear sides of the top of the shift plate 66 are provided with bevel edges for pushing the driven rods 65 to rotate back and forth.

[0045] like Figure 8-9 As shown, the switching mechanism 6 further includes a return spring 651 for pushing the driven rod 65 to move toward the shift plate 66 , and the top end of the shift plate 66 is provided with an oblique edge for pushing the driven rod 65 to retract into the inside of the rotating ring 62 .

[0046] Specifically, the two ends of the return spring 651 are connected to the rotating ring 62 and the driven rod 65 respectively. Figure 8 and Fig. 9 In the process, the return spring 651 pushes the driven rod 65 to move rightward and outward; the bevels on the front and rear sides of the top of the shift plate 66 are used to drive the two driven rods 65 to rotate forward and backward, and the bevel on the left side of the top of the shift plate 66 is used to drive the driven rod 65 to move leftward; initially as Figure 8As shown, the driven rod 65 on the front side is located in front of the dial plate 66, and the driven rod 65 on the rear side is located on the left side of the dial plate 66. After the fixed plate 61 moves up, it drives the rotating ring 62 to move up. During the upward movement, the rotating ring 62 does not rotate. After cleaning the metal on the outside of the protective cover 33, the fixed plate 61 drives the rotating ring 62 to move down. After the rotating ring 62 moves down, the driven rod 65 on the rear side contacts the beveled edge on the rear side of the dial plate 66, and the dial plate 66 pushes the rotating ring 62 to rotate clockwise, so that the driven rod 65 on the rear side moves to the rear of the dial plate 66, and the driven rod 65 on the front side contacts the dial plate 66. After the beveled edge on the left side of the end contacts, it moves to the left side of the paddle plate 66; after moving down again, the beveled edge on the front side of the paddle plate 66 cooperates with the front driven rod 65 to drive the swivel 62 to rotate counterclockwise; this cycle realizes the function of driving the swivel 62 to rotate back and forth within a fixed range after each downward movement of the swivel 62, and then the swivel 62 can drive different magnetic bars 34 and protective covers 33 to move up each time it moves up, thereby realizing the function of automatically switching the protective covers 33 for cleaning, eliminating the trouble of setting up multiple sets of drive systems for driving different protective covers 33 to move up and down.

[0047] like Figure 8-9 As shown, the switching mechanism 6 also includes: a telescopic rod 67 arranged in an inclined state between the fixed plate 61 and the rotating ring 62, and the two ends of the telescopic rod 67 are respectively movably hinged to the fixed plate 61 and the rotating ring 62; and an extension spring 68 for pushing the telescopic rod 67 to extend outward.

[0048] Specifically, mounting plates are provided at both ends of the telescopic rod 67, and both ends of the extension spring 68 are respectively connected to the two mounting plates. The telescopic rod 67 maintains a stable tilt under the push of the extension spring 68, so that the swivel 62 maintains a stable position after rotation, and the swivel 62 can be stably engaged with different magnetic bars 34.

[0049] Working principle: In the carbon conversion wastewater treatment system, it is necessary to recycle the metal impurities in the wastewater. When the device is in use, the wastewater is sent into the wastewater treatment pool 1, and the wastewater flows from left to right. The bottom end of the protective cover 33 is inserted into the wastewater, and the rotating rod 31 is started to rotate, and the protective cover 33 rotates accordingly, stirring the wastewater, which can improve the fluidity of the wastewater. The magnetic field generated by the magnetic rod 34 can more fully contact the metal in the wastewater, thereby improving the adsorption effect of the metal in the wastewater. In addition, when the treatment agent is added to the wastewater, the stirring protective cover 33 can also accelerate the reaction between the agent and the wastewater; During the rotation of the support disc 32, the metal attached to the outside of the protective cover 33 has a tendency to be thrown outward to the inside of the collection frame 41 under the action of centrifugal force. After working for a period of time, more metal is adsorbed on the outside of the protective cover 33. In order to ensure that the magnetic rod 34 can normally adsorb and separate the metal in the wastewater, it is necessary to clean the metal attached to the outside of the protective cover 33. At this time, the support disc 32 does not stop rotating, and the driving rod 51 is started to drive the fixed plate 61 and the rotating ring 62 to move upward, and the rotating ring 62 drives half of the magnetic rods 34 and the protective cover 33 to move upward; After the protective cover 33 moves upward, the bottom end of the stopper 54 passes through the through slot and contacts the baffle 331 on the protective cover 33, so that the protective cover 33 stops moving upward, and the oblique edge pushes the card plate 53 and the convex plate 341 to separate. Without the obstruction of the card plate 53, the driving rod 51 continues to move upward and drives the magnetic rod 34 to move upward alone, so that the magnetic rod 34 and the protective cover 33 are separated from each other. After the magnetic bar 34 is separated from the protective cover 33, the magnetic bar 34 loses its suction force, and the metal originally adsorbed on the outside of the protective cover 33 is thrown outward under the action of centrifugal force and falls into the collection frame 41, thus realizing the function of separating and separately collecting the metals in the wastewater without stopping the machine for cleaning; During the process of cleaning the metal outside the protective cover 33, the other half of the protective cover 33 and the magnetic rod 34 are still stirring and separating the metal in the wastewater in the wastewater treatment tank 1, and the wastewater treatment work is not interrupted; After the metal on the outside of the group of protective covers 33 is cleaned, the driving rod 51 is started to move downward. When the driving rod 51 moves downward, it first drives the magnetic bar 34 to move downward and insert into the protective cover 33. Then, the driving rod 51 continues to move downward, driving the protective cover 33 to move downward together through the convex plate 341, so that the protective cover 33 is reinserted into the installation groove 321. After the swivel 62 moves downward, the top bevel of the dial plate 66 contacts one of the driven rods 65 and drives the swivel 62 to rotate, and the engaging block 64 at the bottom end of the swivel 62 separates from the original engaging seat 63 on the magnetic rod 34 and engages with the engaging seat 63 on the other half of the magnetic rod 34; the driving rod 51 is started to move upward again, driving the other half of the magnetic rod 34 and the protective cover 33 to move upward to perform metal cleaning; this cycle is repeated, and different magnetic rods 34 and protective covers 33 are driven upward each time the swivel 62 moves upward, realizing the function of automatically switching the protective cover 33 for alternate cleaning, and eliminating the trouble of setting up multiple sets of driving systems that respectively drive different protective covers 33, magnetic rods 34, guide plates 43 and swivel 62 and other structures.
