It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1-Figure 5 As shown, it is a structural diagram of a clean production wastewater treatment equipment provided by an embodiment of the present invention, comprising an upper box body 1, a lower box body 15, a filter press mechanism 100, a directional drive mechanism 200, a diversion filter mechanism 300 and an elastic reciprocating mechanism 400, wherein the upper box body 1 is provided with a water inlet pipe 2, the lower box body 15 is arranged at the bottom end of the upper box body 1, and an isolation box 14 is installed in the lower box body 15 directly below the upper box body 1; the filter press mechanism 100 is arranged in the upper box body 1, and when the filter press mechanism 100 is working, it filters the water flow entering the upper box body 1 through the water inlet pipe 2; the directional drive mechanism 200 rotates The directional drive mechanism 200 is dynamically installed on the lower box body 15, and the directional drive mechanism 200 is connected to the filter press mechanism 100, and pushes the filter press mechanism 100 to slide in the height direction when working; the diversion filtering mechanism 300 is provided with multiple groups, and the diversion filtering mechanisms 300 are respectively installed on the sides of the upper box body 1, and are all connected to the driving shaft 9 in the directional drive mechanism 200; the elastic reciprocating mechanism 400 is installed on the lower box body 15, and the elastic reciprocating mechanism 400 is connected to the driving shaft 9, and the working end of the elastic reciprocating mechanism 400 scrapes out the impurities adsorbed on the adsorption rod 20 in the diversion filtering mechanism 300 when it is still working.

[0040] In one example of the present invention, the drive shaft 9 is driven by an external motor, which is a forward and reverse motor, and is electrically connected to an independently arranged controller to facilitate the regulation of the working process. At the same time, a water outlet pipe is connected to the bottom side of the lower box body 15 to discharge the filtered water to the outside, and an electromagnetic valve is installed on the water outlet pipe as needed.

[0041] like Figure 1 As shown, as a preferred embodiment of the present invention, the filter press mechanism 100 includes a conical barrel 3, a guide rod 4, a rubber rod 5, an elastic membrane 6, a guide groove 7 and a movable plate 8;

[0042] The conical barrel 3 is fixedly mounted on the inner wall of the upper box body 1, a guide rod 4 is slidably mounted on the conical barrel 3, a rubber rod 5 is mounted on the top of the guide rod 4, and an elastic membrane 6 is arranged between adjacent rubber rods 5;

[0043] The free end of the elastic membrane 6 is slidably connected to a guide groove 7 provided on the inner side of the conical barrel 3, and a filter layer is provided in the guide groove 7 to facilitate filtering;

[0044] A movable plate 8 is also fixedly mounted on the conical barrel 3 , and a sealing ring is mounted on the outer ring of the movable plate 8 to improve the sealing performance during movement.

[0045] In one embodiment of the present invention, when the guide rod 4 is forced to move downward, the guide rod 4 pulls the rubber rod 5 to move downward synchronously, and the rubber rod 5 undergoes certain deformation during the sliding process along the guide groove 7. The elastic membrane 6 moves synchronously with the rubber rod 5 and adjusts the opening area during the movement, so that the elastic membrane 6 is in a contracted state during the movement from top to bottom, and remains unchanged when it reaches the top and continues to move upward, so that the water flows downward along the gap between the conical barrel 3 and the elastic membrane 6; at the same time, in addition to using deformable materials, the rubber rod 5 can also be replaced by a sleeve rod, and the sleeve rod has a built-in compression spring to ensure that the free end slides along the guide groove 7 during lifting.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, as another preferred embodiment of the present invention, the directional drive mechanism 200 includes a drive shaft 9, a cam 10, a fixing block 11, a guide rod 12 and an elastic support member 13;

[0047] The drive shaft 9 is rotatably mounted on the lower box 15, and the end of the drive shaft 9 is fixedly connected to the cam 10;

[0048] A guide rod 12 is slidably mounted on the upper box body 1, a fixing block 11 is mounted on the bottom end of the guide rod 12, and the fixing block 11 abuts against the cam 10;

[0049] The elastic support member 13 is also sleeved on the guide rod 2 12 , and the elastic support member 13 is located between the upper box body 1 and the movable plate 8 .

[0050] In one example of the present invention, the drive shaft 9 rotates driven by an external motor, and the cam 10 rotates synchronously with the drive shaft 9. The cam 10 pushes the fixed block 11 at the corresponding position to move, and the fixed block 11 pulls the guide rod 2 12, the guide rod 1 4 and the movable plate 8 to slide along the upper box body 1. During this process, the elastic support member 13 is subjected to force and elastically deforms.

[0051] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the diversion filtering mechanism 300 includes a drain pipe 16, a diversion pipe 17, a nozzle 18, a bevel gear 19, an adsorption rod 20 and a bevel gear 21;

[0052] The drainage pipe 16 is installed on the upper box body 1 and the lower box body 15, and a diverter pipe 17 is installed at the bottom of the drainage pipe 16, and a plurality of nozzles 18 are arranged at the bottom of the diverter pipe 17;

[0053] The bevel gear 19 is fixedly mounted on the driving shaft 9 , and the adsorption rod 20 is rotatably mounted on the isolation box 14 . The adsorption rod 20 is also transmission-connected to the bevel gear 19 via the bevel gear 21 .

[0054] In one embodiment of the present invention, the drain pipe 16 can be used in conjunction with a separately arranged pump body when in operation, so that when the movable plate 8 is lower than the height of the drain pipe 16, the liquid between the conical barrel 3 and the movable plate 8 is discharged outwardly, and the water flows along the drain pipe 16 into the diversion pipe 17 and is finally sprayed outwardly through the nozzle 18.

[0055] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the elastic reciprocating mechanism 400 includes a sleeve 22, an annular triangular cone 23, a spherical protrusion 24, a groove 25 and a material receiving box 26;

[0056] The sleeve 22 is movably mounted on the lower box 15, and the sleeve 22 and the adsorption rod 20 are arranged with the same diameter. An annular triangular cone 23 is arranged on the inner side of the sleeve 22, and a spherical protrusion 24 is installed on the adsorption rod 20;

[0057] A groove 25 is formed inside the sleeve 22 along the axial direction, and a material receiving box 26 is placed at a corresponding position outside the lower box body 15 to collect impurities discharged from the sleeve 22 .

[0058] In one example of the present invention, after the adsorption rod 20 filters the water flow sprayed from the nozzle 18, the water flow drips outward along the adsorption rod 20, and the debris adheres to the adsorption rod 20. At this time, the sleeve 22 moves reciprocatingly along the adsorption rod 20, and the debris attached to the adsorption rod 20 is scraped off by the arranged annular triangular cone 23. The debris moves along the opened groove 25 and finally falls into the receiving box 26 when the sleeve 22 is led out.

[0059] like Figure 1 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the elastic reciprocating mechanism 400 further includes a transmission shaft 27, a synchronous belt 28, an incomplete gear 29, a concave tooth portion 30, an elastic support member 2 31 and a bracket 32;

[0060] The transmission shaft 27 is rotatably connected to a support arranged outside the lower box 15, a double-track pulley is provided on the drive shaft 9, a single-track pulley is provided on the transmission shaft 27, and the double-track pulley and the single-track pulley are connected by a synchronous belt 28;

[0061] The incomplete gear 29 is mounted on the end of the transmission shaft 27, and the incomplete gear 29 is meshed with the concave tooth portion 30 provided on the sleeve 22;

[0062] The bracket 32 ​​is fixedly mounted on the outside of the lower box 15 , and the bracket 32 ​​is slidably connected to the sleeve 22 . An elastic support member 2 31 is also installed between the bracket 32 ​​and the fixing block at the bottom of the sleeve 22 .

[0063] In one example of the present invention, when the drive shaft 9 rotates, it drives the double-track pulley to rotate synchronously. The double-track pulley drives the single-track pulleys on both sides and the transmission shaft 27 to rotate synchronously through the synchronous belt 28. The transmission shaft 27 drives the incomplete gear 29 installed at the end to rotate. Since the incomplete gear 29 is engaged with the concave tooth portion 30, the sleeve 22 can be pushed to move in the axial direction. During this process, the elastic support member 2 31 is subjected to force and elastically deforms, and pushes the sleeve 22 to reciprocate during continuous rotation.

[0064] In summary, water flows along the water inlet pipe 2 and then enters the conical barrel 3. The external motor drives the drive shaft 9 to rotate, and the cam 10 rotates synchronously with the drive shaft 9. The cam 10 pushes the fixed block 11 at the corresponding position to move, and the fixed block 11 pulls the guide rod 2 12, the guide rod 1 4 and the movable plate 8 to slide along the upper box body 1. During this process, the elastic support member 13 is elastically deformed by force. When the guide rod 1 4 is forced to move downward, the guide rod 1 4 pulls the rubber rod 5 to move downward synchronously. The rubber rod 5 undergoes a certain deformation during the sliding process along the guide groove 7. The elastic membrane 6 moves synchronously with the rubber rod 5. The elastic membrane 6 is in a contracted state during the movement from the top to the bottom, and remains unchanged when it reaches the top and continues to move upward, so that the water flows downward along the gap between the conical barrel 3 and the elastic membrane 6, passes through the filter layer and falls on the movable plate 8. When the movable plate 8 is lower than the height of the drain pipe 16, the liquid between the conical barrel 3 and the movable plate 8 is discharged outward, and the water flows along the drain pipe 16 into the diverter pipe 17, and finally sprays outward through the nozzle 18. After the adsorption rod 20 filters the water sprayed from the nozzle 18, the water flows outward along the adsorption rod 20 and drips through the outlet pipe to the The debris is attached to the adsorption rod 20, and the driving shaft 9 drives the double-track pulley to rotate synchronously when the driving shaft 9 rotates. The double-track pulley drives the single-track pulleys on both sides and the transmission shaft 27 to rotate synchronously through the synchronous belt 28. The transmission shaft 27 drives the incomplete gear 29 installed at the end to rotate. Since the incomplete gear 29 is engaged with the concave tooth portion 30, the sleeve 22 can be pushed to move in the axial direction. In this process, the elastic support member 31 is elastically deformed by force, and the sleeve 22 is pushed to reciprocate in the process of continuous rotation. The sleeve 22 moves back and forth along the adsorption rod 20, and the annular triangular cone 23 is arranged to push the debris attached to the adsorption rod 20. The debris is scraped off, and the debris moves along the groove 25, and finally falls into the receiving box 26 when the sleeve 22 is discharged. The device can increase the extrusion and filtration speed of the water flow by pressurizing during the wastewater treatment process, and automatically scrape off the attached debris after a single filtration, thereby avoiding the accumulation of debris and affecting the filtration work; in addition, during the secondary filtration, the flow can be divided into parts to avoid excessive water flow and reduce the filtration effect, and the adsorption rod 20 can reciprocate along the axial direction during filtration, and the debris adsorbed by the adsorption rod 20 can be quickly discharged outward while continuous cleaning is performed, which can not only improve the filtration efficiency, but also avoid the attachment of debris and reduce the filtration quality.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
