Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a powder metallurgy wastewater discharge device. Background Technology

[0002] Powder metallurgy is a process that manufactures parts by pressing and sintering metal powders. This process often generates large amounts of wastewater containing fine metal particles, oil, coolant residue, and other chemical additives. Direct discharge of this wastewater not only wastes resources but also pollutes the environment; therefore, it must be effectively treated to meet emission standards.

[0003] Common filtration devices often rely on fixed filter screens or filter cartridges, which are prone to clogging when treating wastewater containing high concentrations of suspended solids, leading to a decrease in filtration efficiency and even requiring frequent shutdowns for manual cleaning. This seriously affects the continuity and stability of production. In addition, due to the strong adhesion and wide particle size distribution of impurities in powder metallurgy wastewater, static filter media cannot completely remove the attached impurities. After long-term use, they are prone to forming a caking layer, further reducing the separation effect.

[0004] Therefore, the present invention provides a powder metallurgy wastewater discharge device to solve the above-mentioned problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a powder metallurgy wastewater discharge device to solve the problem of automatically squeezing and filtering wastewater to ensure separation effect, while automatically cleaning the inside of the device to avoid impurity adsorption.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A powder metallurgy wastewater discharge device includes a discharge tank, an extrusion assembly, a compression filtration assembly, a collection assembly, and a cleaning assembly. The extrusion assembly is slidably connected inside the discharge tank, the compression filtration assembly is located between the extrusion assemblies, the collection assembly is located at the bottom inner part of the discharge tank, and the cleaning assembly is located on one side of the extrusion assembly. The extrusion assembly includes an extrusion plate, an extrusion filter plate, a bidirectional lead screw, and a reciprocating lead screw. The reciprocating lead screw is drivenly connected to the bidirectional lead screw. The extrusion plate is threadedly connected to the outer wall of the reciprocating lead screw, and the extrusion filter plate is slidably connected inside the extrusion plate. The compression filtration assembly includes a compression filter plate and a separation inclined block. The compression filter plate is threadedly connected to the outer wall of the bidirectional lead screw, and the separation inclined block matches the compression filter plate. The collection assembly includes a collection tank and a sealing plate. The collection tank is located inside the discharge tank. At the bottom, the sealing plate is slidably connected to the top of the collection box, and the sealing plate matches the compression filter plate; the cleaning assembly includes a push plate and a waste bin, the push plate is installed on one side of the compression plate, the waste bin is connected to the push plate, and the waste bin is installed on the outer wall of the discharge box; this device, through the setting of the compression filter plate, allows the two compression filter plates to slide and compress the wastewater during wastewater treatment, avoiding the slowness and clogging caused by static filtration, achieving solid-liquid separation. At the same time, after the two compression filter plates are compressed, the liquid can be discharged and the solid can be sent into the interior of the collection box for easy cleaning. Simultaneously, during compression, the cleaning device is cleaned and the waste is compressed to prevent it from remaining inside the device. By realizing multiple cleaning functions, the cleanliness of the discharged wastewater is ensured, and the phenomenon of impurities affecting the discharge is avoided.

[0007] Preferably, the extrusion assembly further includes a drive motor and a sliding sleeve; the bidirectional lead screw is fixedly connected to the output end of the drive motor, the bidirectional lead screw is rotatably connected to the inner wall of the discharge box, and connecting bevel teeth are installed on the outer wall of the bidirectional lead screw; the reciprocating lead screw is rotatably connected to the outer wall of the extrusion plate, the upper limit of the outer wall of the reciprocating lead screw is slidably connected to the sliding sleeve, and sliding bevel teeth are installed on the outer wall of the sliding sleeve, the sliding bevel teeth meshing with the connecting bevel teeth; when this device is in use, wastewater is introduced between the two extrusion plates, and the drive motor is started to rotate the reciprocating lead screw, thereby driving the extrusion plates to move. The two extrusion plates move relative to each other, and the wastewater in the gap between the two extrusion plates will be squeezed and filtered, realizing the transformation from static filtration to dynamic filtration, accelerating the filtration efficiency, and avoiding the phenomenon of slowing down the filtration due to clogging.

[0008] Preferably, the compression filter assembly further includes a fixing plate and a cleaning plate; the fixing plate is threadedly connected to the outer wall of the bidirectional lead screw, the compression filter plate is slidably connected to one end inside the fixing plate, a closing spring is fixedly installed at one end of the compression filter plate, the other end of the closing spring is fixedly connected to the inner wall of the fixing plate, and the other end of the compression filter plate matches the bottom of the separating inclined block; a cleaning plate is slidably connected to the other end of the fixing plate, a cleaning spring is fixedly installed at one end of the cleaning plate, the other end of the cleaning spring is fixedly connected to the inner wall of the fixing plate, and the other end of the cleaning plate abuts against the outer wall of the compression filter plate; in the initial state, the compression filter plates of this device, under the action of the closing spring, make the two compression filter plates in a relative state, so that the fixing plate and the compression filter plates achieve the function of closing, and at the same time, under the action of the cleaning spring, the cleaning plate extends outward and abuts against the outer wall of the compression filter plate.

[0009] Preferably, the collection assembly further includes a partition, a circulating filter plate, and a top plate; the partition is fixedly installed in the lower part of the discharge box and located in the upper part of the collection box; the circulating filter plate is located on one side of the partition and is fixedly connected to the partition; the sealing plate is slidably connected to the inside of the partition, a sealing spring is fixedly installed at one end of the sealing plate, and the other end of the sealing spring is fixedly connected to the inner wall of the partition; a top plate is fixedly installed on the top of the sealing plate, and the top plate matches the side wall of the extrusion plate; when the drive motor drives the reciprocating screw to rotate, the device will be subjected to the action of two bevel gears. The synchronous rotation of the bidirectional lead screw causes the fixed plate to move. As the compression plate moves, the sliding sleeve on the outer wall of the reciprocating lead screw follows, ensuring the bidirectional lead screw remains in a driving connection with the reciprocating lead screw. When the fixed plate lowers the compression filter plate, the lower part of the compression filter plate abuts against the separating inclined block. The separating inclined block is installed on the upper part of the inner wall of the discharge box. As the compression filter plate descends, most of the waste material is deposited at the bottom of the discharge box. After the compression filter plate passes the separating inclined block, the closing spring causes the compression filter plate to close again, clearing the middle and upper parts of the waste material. Impurities are compressed, and as the compression filter plate descends, the cleaning plate abuts against the outer wall of the compression filter plate, facilitating cleaning of the outer wall of the compression filter plate. During the relative displacement of the compression filter plates and the compression filtration process, the compression plate will abut against one end of the abutment plate, causing the sealing plate to open. This allows the collection box and the gap between the two compression plates to communicate with each other. Under the action of the descending compression filter plate, impurities are compressed into the interior of the collection box, achieving an automatic compression and collection function. When the compression filter plate resets, the separating inclined block allows the compression filter plate to temporarily open, and newly entering wastewater and impurities will be located in the lower part of the compression filter plate, facilitating reciprocating compression. The device, through the configuration of a compression filter plate, enables the compression of filtered impurities, avoiding excessive space occupation. The compression filter plate is easily opened and closed for effective impurity compression, and the separation inclined block prevents upper impurities from failing to descend. Furthermore, the device automatically retracts and compresses the filter plate during compression, preventing stagnation and compression. Simultaneously, the device cleans during compression and squeezing to prevent impurity blockage, achieving integrated operation by linking collection, compression, filtration, and cleaning.

[0010] Preferably, a guide plate is fixedly installed on one side of the extrusion plate, the height of the guide plate decreases from the outside to the inside, and a push plate is fixedly installed on the outer end of the guide plate, the bottom of the push plate abutting against the upper part of the circulating filter plate.

[0011] Preferably, the cleaning assembly further includes a collecting plate and a pressure spring; a receiving port is provided on the inner wall of the waste bin, and a collecting plate is slidably connected inside the receiving port. One side of the collecting plate matches the push plate, and a pressure spring is fixedly installed on the top of the collecting plate. The other end of the pressure spring is fixedly connected to the inner wall of the waste bin. When the extrusion plate performs the extrusion process, the filtered water undergoes a second filtration process through the circulating filter plate, achieving a multi-filtration effect. At the same time, the filtered impurities will remain on the upper part of the circulating filter plate. When the extrusion plate resets, the upper part of the circulating filter plate is cleaned by the push plate, so that the impurities on the upper part are pushed into the interior of the waste bin. When the push plate and the collecting plate abut against each other, the collecting plate moves upward, opening the receiving port to achieve automatic collection and discharge.

[0012] Preferably, a return spring is fixedly installed on the outer wall of the extrusion filter plate, and the other end of the return spring is fixedly connected to the inner side wall of the extrusion plate.

[0013] Preferably, the device includes an oscillation assembly comprising a rotating shaft and an eccentric wheel. The rotating shaft is rotatably connected to the upper part of the guide plate, and an eccentric wheel is mounted on the outer wall of the rotating shaft, the eccentric wheel matching the extrusion filter plate. A drive bevel gear is fixedly mounted on the upper outer wall of the rotating shaft, the drive bevel gear meshing with the rotating bevel gear, and the rotating bevel gear is fixedly mounted on the outer wall of one end of the reciprocating screw. When the reciprocating screw drives the extrusion plate for extrusion filtration, to avoid incomplete cleaning of the cleaning plate, the device synchronously drives the rotating shaft to rotate, causing the eccentric wheel to rotate. The eccentric wheel reciprocates against the extrusion filter plate, causing the extrusion filter plate to oscillate back and forth, facilitating deep and thorough cleaning and preventing the adsorption of impurities that are difficult to remove.

[0014] The beneficial effects of this invention are as follows: 1. This device, through the arrangement of the squeeze filter plates, allows the two squeeze filter plates to slide and squeeze the wastewater during wastewater treatment, avoiding the slowness and clogging caused by static filtration, and achieving solid-liquid separation. At the same time, after the two squeeze filter plates are squeezed, the liquid can be discharged and the solid can be sent into the collection tank for easy cleaning. Simultaneously, the device is cleaned during squeezing, and the waste material is compressed to prevent it from remaining inside the device. By realizing multiple cleaning functions, the cleanliness of the discharged wastewater is guaranteed, and the phenomenon of impurities affecting the discharge is avoided.

[0015] 2. When using this device, wastewater is introduced between the two extrusion plates. At this time, the drive motor is started, which causes the reciprocating screw to rotate, thereby driving the extrusion plates to move. The two extrusion plates move relative to each other, and the wastewater in the gap between the two extrusion plates will be squeezed and filtered, realizing the transformation from static filtration to dynamic filtration, accelerating the filtration efficiency, and avoiding the phenomenon of slowing down the filtration due to clogging.

[0016] 3. This device, through the configuration of the compression filter plate, enables the device to compress filtered impurities, avoiding excessive space occupation. The compression filter plate can be easily opened and closed to compress impurities, and the separation inclined block prevents upper impurities from failing to descend. Furthermore, the device automatically retracts and compresses the filter plate during compression, preventing any failure to descend or compress. Simultaneously, the device cleans during compression and squeezing to prevent impurity blockage, achieving integrated operation by linking collection, compression, filtration, and cleaning.

[0017] 4. During the extrusion process by the extrusion plate, the filtered water undergoes a second filtration process through the circulating filter plate, achieving a multi-stage filtration effect. Simultaneously, the filtered impurities remain on the upper part of the circulating filter plate. When the extrusion plate resets, the upper part of the circulating filter plate is cleaned by the push plate, causing the impurities on the upper part to be pushed into the waste bin. When the push plate and the collection plate meet, the collection plate moves upward, opening the receiving port to achieve automatic collection and discharge.

[0018] 5. When the reciprocating screw drives the extrusion plate for extrusion filtration, in order to avoid incomplete cleaning of the cleaning plate, the device will simultaneously drive the rotating shaft to rotate when the reciprocating screw rotates, so that the eccentric wheel rotates. The eccentric wheel reciprocates against the extrusion plate, causing the extrusion plate to vibrate back and forth, which facilitates deep and thorough cleaning and avoids the phenomenon of impurities adhering and being difficult to clean.

Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] A powder metallurgy wastewater discharge device, as shown in the attached document. Figure 1-3As shown, the system includes a discharge box 1, a compression assembly, a compression filter assembly, a collection assembly, and a cleaning assembly. The compression assembly is slidably connected inside the discharge box 1, the compression filter assembly is located between the compression assemblies, the collection assembly is located at the inner bottom of the discharge box 1, and the cleaning assembly is located on one side of the compression assembly. The compression assembly includes a compression plate 5, a compression filter plate 11, a bidirectional lead screw 3, and a reciprocating lead screw 4. The reciprocating lead screw 4 is drivenly connected to the bidirectional lead screw 3. The compression plate 5 is threadedly connected to the outer wall of the reciprocating lead screw 4, and the compression filter plate 11 is slidably connected inside the compression plate 5. The compression filter assembly includes a compression filter plate 6 and a separation inclined block 10. The compression filter plate 6 is threadedly connected to the outer wall of the bidirectional lead screw 3, and the separation inclined block 10 matches the compression filter plate 6. The collection assembly includes a collection box 14 and a sealing plate 8. The collection box 14 is located at the inner bottom of the discharge box 1, and the sealing plate 8 is slidably connected for sealing. At the top of the collection box 14, the sealing plate 8 matches the compression filter plate 6; the cleaning assembly includes a push plate 9 and a waste bin 2. The push plate 9 is installed on one side of the extrusion plate 5, and the waste bin 2 is connected to the push plate 9. The waste bin 2 is installed on the outer wall of the discharge box 1; by setting the extrusion filter plate 11, this device can allow the two extrusion filter plates 11 to slide and extrude the wastewater during wastewater treatment, avoiding the slowness and clogging caused by static filtration, and achieving solid-liquid separation. At the same time, after the two extrusion filter plates 11 are extruded, the liquid can be discharged and the solid can be sent into the interior of the collection box 14 for easy cleaning. Simultaneously, during extrusion, the cleaning device is used to clean the wastewater and compress it to prevent it from remaining inside the device. By realizing multiple cleaning functions, the cleanliness of the discharged wastewater is ensured, and the phenomenon of impurities affecting the discharge is avoided.

[0023] As attached Figure 3-4 As shown, the extrusion assembly also includes a drive motor 101 and a sliding sleeve 402; a bidirectional lead screw 3 is fixedly connected to the output end of the drive motor 101, and the bidirectional lead screw 3 is rotatably connected to the inner wall of the discharge box 1. A connecting bevel tooth 301 is installed on the outer wall of the bidirectional lead screw 3; a reciprocating lead screw 4 is rotatably connected to the outer wall of the extrusion plate 5, and a sliding sleeve 402 is slidably connected to the upper limit of the outer wall of the reciprocating lead screw 4. A sliding bevel tooth 401 is installed on the outer wall of the sliding sleeve 402, and the sliding bevel tooth 401 meshes with the connecting bevel tooth 301; when this device is in use, wastewater is introduced between the two extrusion plates 5. At this time, the drive motor 101 is started, causing the reciprocating lead screw 4 to rotate, thereby driving the extrusion plates 5 to move. The two extrusion plates 5 move relative to each other, and the wastewater in the gap between the two extrusion plates 5 will be squeezed and filtered, realizing the transformation from static filtration to dynamic filtration, accelerating the filtration efficiency, and avoiding the phenomenon of slowing down the filtration due to blockage.

[0024] As attached Figure 2-3 and attached Figure 5As shown, the compression filter assembly also includes a fixing plate 601 and a cleaning plate 602; the fixing plate 601 is threadedly connected to the outer wall of the bidirectional lead screw 3, the compression filter plate 6 is slidably connected to one end inside the fixing plate 601, a closing spring 603 is fixedly installed at one end of the compression filter plate 6, the other end of the closing spring 603 is fixedly connected to the inner wall of the fixing plate 601, and the other end of the compression filter plate 6 matches the bottom of the separating inclined block 10; the cleaning plate 602 is slidably connected inside the other end of the fixing plate 601, and one end of the cleaning plate 602 is fixedly installed with... Cleaning spring 604 is fixedly connected at one end to the inner wall of fixing plate 601, and cleaning plate 602 is abutted against the outer wall of compression filter plate 11. In the initial state, the compression filter plate 6 of this device is in a relative state under the action of closing spring 603, so that fixing plate 601 and compression filter plate 6 achieve the function of closing. At the same time, under the action of cleaning spring 604, cleaning plate 602 extends outward and abuts against the outer wall of compression filter plate 11.

[0025] As attached Figure 6As shown, the collection assembly also includes a partition 12, a circulating filter plate 13, and a top plate 802; the partition 12 is fixedly installed in the lower part of the discharge box 1 and located in the upper part of the collection box 14; the circulating filter plate 13 is located on one side of the partition 12 and is fixedly connected to the partition 12; the sealing plate 8 is slidably connected to the inside of the partition 12; a sealing spring 801 is fixedly installed at one end of the sealing plate 8, and the other end of the sealing spring 801 is fixedly connected to the inner wall of the partition 12; a top plate 802 is fixedly installed on the top of the sealing plate 8, and the top plate 802 matches the side wall of the extrusion plate 5; when the drive motor 101 drives the reciprocating screw 4 to rotate, the two bevel gears will simultaneously drive the double... The screw 3 rotates, causing the bidirectional screw 3 to drive the fixed plate 601 to move. As the compression plate 5 moves, the sliding sleeve 402 on the outer wall of the reciprocating screw 4 follows, ensuring the bidirectional screw 3 is always in a driving connection with the reciprocating screw 4. When the fixed plate 601 drives the compression filter plate 6 to descend, the lower part of the compression filter plate 6 will abut against the separating inclined block 10. The separating inclined block 10 of this device is installed on the upper part of the inner wall of the discharge box 1. When the compression filter plate 6 descends, most of the waste material is deposited at the bottom of the discharge box 1. After the compression filter plate 6 passes the separating inclined block 10, the closing spring 603 causes the compression filter plate 6 to close again, affecting the middle part. The impurities in the upper part are compressed. Simultaneously, as the compression filter plate 6 descends, the cleaning plate abuts against the outer wall of the compression filter plate 11, facilitating cleaning of the outer wall of the compression filter plate 11. During the relative displacement of the compression filter plates 11 and the compression filtration process, the compression plate 5 abuts against one end of the abutment plate 802, causing the sealing plate 8 to open. The collection box 14 and the gaps between the two compression plates 5 are interconnected. Under the action of the compression filter plate 6 descending, the impurities are compressed into the interior of the collection box 14, achieving the function of automatic compression and collection. When the compression filter plate 6 resets, the separating inclined block 10 allows the compression filter plate 6 to temporarily open, and newly entering wastewater and impurities will be located in the lower part of the compression filter plate 6. This device facilitates reciprocating compression processing. Through the configuration of the compression filter plate 6, it can compress filtered impurities, avoiding excessive space occupation. The compression filter plate 6 can be easily opened and closed to compress impurities, and the separation inclined block 10 prevents upper impurities from failing to descend. Furthermore, when the compression filter plate 11 is squeezed, it automatically retracts to compress the filter plate 6, preventing any failure to descend or compress. Simultaneously, the device cleans during compression and squeezing to prevent impurity blockage, achieving integrated operation by linking collection, compression, squeezing, and cleaning.

[0026] As attached Figure 2-3As shown, a guide plate 901 is fixedly installed on one side of the extrusion plate 5. The height of the guide plate 901 decreases from the outside to the inside. A push plate 9 is fixedly installed on the outer end of the guide plate 901. The bottom of the push plate 9 abuts against the upper part of the circulating filter plate 13.

[0027] As attached Figure 7 As shown, the cleaning assembly also includes a collection plate 201 and a pressure spring 202; a receiving port 203 is provided on the inner wall of the waste bin 2, and the collection plate 201 is slidably connected to the inside of the receiving port 203.

The other end of the pressure spring 202 is fixedly connected to the inner wall of the waste bin 2. When the extrusion plate 5 performs the extrusion process, the filtered water is filtered again through the circulating filter plate 13 to achieve the effect of multiple filtrations. At the same time, the filtered impurities will remain on the upper part of the circulating filter plate 13. When the extrusion plate 5 is reset, the upper part of the circulating filter plate 13 is cleaned by the push plate 9, so that the impurities on the upper part are pushed to the inside of the waste bin 2 by the push plate 9. When the push plate 9 and the collection plate 201 abut against each other, the collection plate 201 moves upward and opens the receiving port 203 to achieve automatic collection and discharge.

[0028] As attached Figure 8 As shown, a reset spring 501 is fixedly installed on the outer wall of the extrusion filter plate 11, and the other end of the reset spring 501 is fixedly connected to the inner side wall of the extrusion plate 5.

[0029] As attached Figure 2-3 As shown, the device includes an oscillation assembly, which comprises a rotating shaft 7 and an eccentric wheel 701. The rotating shaft 7 is rotatably connected to the upper part of the guide plate 901, and the eccentric wheel 701 is installed on the outer wall of the rotating shaft 7, matching the extrusion filter plate 11. A drive bevel gear 702 is fixedly installed on the upper outer wall of the rotating shaft 7, and the drive bevel gear 702 meshes with the rotating bevel gear 703, which is fixedly installed on the outer wall of one end of the reciprocating screw 4. When the reciprocating screw 4 drives the extrusion plate 5 for extrusion filtration, in order to avoid the phenomenon of incomplete cleaning of the cleaning plate 602, the device will synchronously drive the rotating shaft 7 to rotate when the reciprocating screw 4 rotates, so that the eccentric wheel 701 rotates. The eccentric wheel 701 reciprocates against the extrusion filter plate 11, causing the extrusion filter plate 11 to oscillate back and forth, which facilitates deep and thorough cleaning and avoids the phenomenon of impurity adsorption and difficulty in cleaning.
