Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment equipment, in particular to wastewater treatment equipment based on wastewater instantaneous backflow flushing and anti-blocking, and also specifically to a treatment process of wastewater treatment equipment based on wastewater instantaneous backflow flushing and anti-blocking. Background Art

[0002] Chinese patent CN116903070B discloses a device for treating heavy metal wastewater, comprising: a wastewater storage component, a wastewater treatment component, an extrusion component and a drive component, wherein an extrusion component is movably installed in the middle of the wastewater storage component through the drive component. Compared with the prior art, the device has the following beneficial effects: the arrangement of the extrusion component and the drive component, the drive component uses the potential energy and impact force of the wastewater as a power source, and no other drive structure is required, thereby reducing the energy consumption of the device and making it more environmentally friendly, in line with the current concept of advocating environmental protection, while driving the extrusion component to move up and down inside the column, and the bristles located on the sides of the lower ends of the conical cover will clean the inner wall of the column, and while the extrusion component moves upward, it drives the wastewater inside the column and inside multiple wastewater treatment components to have a short-term reflux, which can play a cleaning role, avoid the blockage caused by the long-term operation of the biological filter membrane, and greatly reduce the number of later maintenance and replacement of the equipment.

[0003] Although the above technical solution can quickly filter heavy metal wastewater by squeezing water flow, the metal wastewater is still filtered through the biological filter membrane when entering the wastewater treatment component. The impurities filtered by the biological filter membrane will adhere to the surface. The above technical solution will increase the extrusion force of filtering impurities when squeezing water flow, so that fine impurities will quickly penetrate into the biological filter membrane and cause blockage, thereby reducing the service life of the filter membrane. At the same time, the device filters through multiple wastewater treatment components. Although the fluidity can be maintained, it is impossible to accurately understand the flow status of each wastewater treatment component, which makes replacement or cleaning more troublesome. Summary of the invention

[0010] Preferably, the push cleaning block comprises a snap-fit ​​mounting block, and a cleaning brush and an elastic scraping edge are provided at the bottom of the snap-fit ​​mounting block.

[0011] Preferably, the synchronous pushing mechanism comprises a driving collar mounted on the telescopic mounting shaft, and an outer wall of the driving collar is provided with an inclined groove.

[0014] The treatment process of the wastewater treatment equipment based on the instantaneous backflow flushing and blocking prevention of wastewater is implemented by using the wastewater treatment equipment based on the instantaneous backflow flushing and blocking prevention of wastewater.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The kinetic energy conversion mechanism guides the sewage into the water storage chamber of the water storage tank. When the sewage passes through the kinetic energy conversion mechanism, it will drive the working end of the kinetic energy conversion mechanism to perform lifting and lowering movements. When the working end of the kinetic energy conversion mechanism moves, it will drive the telescopic mounting shaft to perform synchronous lifting and lowering movements. When the telescopic mounting shaft moves up and down, it will drive the extrusion bucket and the synchronous pushing mechanism to perform synchronous movements. When the extrusion bucket moves up and down, it will reflux the extruded sewage in the water storage chamber, so that the sewage will quickly flow into the pressure filter rail and the dirt collection box. When the synchronous pushing mechanism moves, it will push multiple compression cleaning heads to move repeatedly inside the pressure filter rail. The repeated movement of the compression cleaning heads will reflux and squeeze the sewage inside the pressure filter rail, so that the sewage entering the pressure filter rail will be quickly filtered out, and the filtered sewage will enter the water outlet chamber. The water outlet chamber will guide and transport the filtered sewage to the area to be treated. At the same time, the compression cleaning head will also clean the filtration area when moving in the pressure filter rail to prevent dirt from adhering to the filtration area of ​​the pressure filter rail, effectively prolonging the service life of the filter layer, and at the same time improving the filtration efficiency of the sewage.

[0017] 2. The pressure detection cover is used to seal the pressure filter rail. When the sewage inside the pressure filter rail is pushed by the compression cleaning head, it can be quickly discharged from the sewage filter layer. When the sewage filter layer is blocked, the sewage flow rate inside the pressure filter rail is very slow, resulting in high internal pressure. The pressure airbag can effectively transmit the pressure to the pressure sensor. The pressure sensor will identify the pressure and determine whether the sewage filter layer of the pressure filter rail is blocked by the pressure value. If blockage occurs, the warning light of the pressure detection cover will light up, prompting the staff to replace and maintain it in time, thereby improving the convenience of maintenance.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figures 1 to 10As shown, the wastewater treatment equipment based on instantaneous backflow flushing and anti-blocking of wastewater includes an automatic cleaning and filtering device for automatically unblocking and cleaning dirt, the automatic cleaning and filtering device includes a water storage chamber 11 and a water outlet chamber 12 installed inside a water storage tank 1, a telescopic mounting shaft 13 is installed at the axial position of the water storage chamber 11, and a plurality of extrusion buckets 14 are installed on the telescopic mounting shaft 13, a plurality of pressure filter rails 2 are installed between the water storage chamber 11 and the water outlet chamber 12, a pressure detection cover 3 is installed at one end of the pressure filter rail 2 away from the water storage tank 1, a compression cleaning head 5 is installed inside the pressure filter rail 2, a plurality of groups of synchronous pushing mechanisms 6 are installed between the telescopic mounting shaft 13 and the water storage chamber 11, and the pushing ends of the synchronous pushing mechanisms 6 are all in contact with the compression cleaning heads 5, a kinetic energy conversion mechanism 4 is installed on the top of the water storage chamber 11, and the driving end of the kinetic energy conversion mechanism 4 is connected to the top of the telescopic mounting shaft 13, and a dirt collection box 7 is installed at the bottom of the water storage chamber 11.

[0032] The kinetic energy conversion mechanism 4 guides the sewage into the water storage chamber 11 of the water tank 1. When the sewage passes through the kinetic energy conversion mechanism 4, it will drive the working end of the kinetic energy conversion mechanism 4 to move up and down. When the working end of the kinetic energy conversion mechanism 4 moves, it will drive the telescopic mounting shaft 13 to move up and down synchronously. When the telescopic mounting shaft 13 moves up and down, it will drive the extrusion bucket 14 and the synchronous pushing mechanism 6 to move synchronously. When the extrusion bucket 14 moves up and down, it will reflux the extruded sewage in the water storage chamber 11, so that the sewage will flow quickly into the pressure filter rail 2 and the dirt collection box 7. When the synchronous pushing mechanism 6 moves, it will push multiple compression cleaning heads 5 to move repeatedly inside the pressure filter rail 2. The repeated movement of the compression cleaning heads 5 will cause the pressure filter rail 2 to move repeatedly. The sewage inside the pressure filter rail 2 is squeezed back and forth, which will cause the sewage entering the pressure filter rail 2 to be quickly filtered out, and the filtered sewage will enter the water outlet chamber 12. The water outlet chamber 12 will guide the filtered sewage to the area to be treated. At the same time, the compression cleaning head 5 will also clean the filter area when moving in the pressure filter rail 2 to prevent dirt from adhering to the filter area of ​​the pressure filter rail 2, effectively improving the filtration efficiency of sewage. The dirt collection box 7 at the bottom of the water storage tank 1 is used to precipitate and collect dirt. The pressure detection cover 3 detects the water pressure inside each pressure filter rail 2 in real time. When the internal water pressure is too high, it means that the pressure filter rail 2 is blocked, which is convenient for the staff to replace it in time and improves the convenience of maintenance. The structure of the extrusion bucket 14 is the same as the extrusion assembly structure proposed in the background technology and is not repeated here.

[0033] See also Figure 3 , Figure 6 and Figure 7As shown, the pressure filter rail 2 includes a control valve 21, which is connected to the inside of the water storage chamber 11. A mounting track 22 is installed at one end of the control valve 21 away from the water storage chamber 11. The mounting track 22 extends through the outside of the water storage tank 1. A limit socket is provided on the lower side of the mounting track 22, and an arc plug plate 23 is installed in the limit socket. A sewage filter layer 222 is provided on the arc plug plate 23.

[0034] The limiting socket of the installation track 22 is used to install the arc plug plate 23. The sewage filter layer 222 on the arc plug plate 23 can effectively filter sewage. When the sewage filter layer 222 is blocked, the staff can first close the filtering equipment and then close the control valve 21 when replacing the sewage filter layer 222. The closing of the control valve 21 effectively prevents the residual sewage inside the equipment from affecting the replacement of the sewage filter layer 222. The staff then opens the pressure detection cover 3. After the pressure detection cover 3 is opened, the staff can directly pull the arc plug plate 23 out of the limiting socket to replace the sewage filter layer 222. The installation track 22 and the arc plug plate 23 are in a spliced ​​state, which can effectively improve the convenience of maintenance.

[0035] See also Figure 3 , Figure 6 and Figure 7 The pressure detection cover 3 is installed on the installation track 22 , a pressure airbag 31 is installed inside the pressure detection cover 3 , a pressure sensor is installed inside the pressure airbag 31 , and a warning light 32 is provided on the outside of the pressure detection cover 3 .

[0036] The pressure detection cover 3 is used to seal the pressure filter rail 2. When the sewage inside the pressure filter rail 2 is pushed by the compression cleaning head 5, it can be quickly discharged from the sewage filter layer 222. When the sewage filter layer 222 is blocked, the sewage flow rate inside the pressure filter rail 2 is very slow, resulting in high internal pressure. The pressure airbag 31 can effectively transmit the pressure to the pressure sensor. The pressure sensor can identify the pressure and determine whether the sewage filter layer 222 of the pressure filter rail 2 is blocked by the pressure value. If blockage occurs, the warning light 32 of the pressure detection cover 3 will light up, prompting the staff to replace and maintain it in time.

[0037] See also Figures 1 to 3 As shown, the kinetic energy conversion mechanism 4 includes a flow rail 41 installed on the top of the water tank 1, the flow rail 41 is connected to the water storage chamber 11, a rotating shaft 42 is installed on the flow rail 41, a driving wheel 43 is installed inside the flow rail 41, the driving wheel 43 is connected to the rotating shaft 42, and a spacing floating mechanism 44 is installed on the side of the flow rail 41.

[0038] The flow rail 41 can effectively guide the sewage to pass through the driving wheel 43 and enter the water storage chamber 11 of the water tank 1. The driving wheel 43 is provided with a plurality of driving blades. When the sewage passes through the driving blades of the driving wheel 43, it will drive the driving wheel 43 to rotate. When the driving wheel 43 rotates, it will drive the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, it will drive the interval floating mechanism 44 to perform interval lifting and lowering movements. When the interval floating mechanism 44 is lifted and lowered, it will drive the telescopic mounting shaft 13 to perform synchronous movement. When the telescopic mounting shaft 13 moves, it can drive the automatic cleaning and filtering device to operate, thereby effectively performing kinetic energy conversion.

[0039] See also Figure 3 and Figure 4 As shown, the interval floating mechanism 44 includes a mounting frame 441 installed on the top of the water tank 1, and a circular lifting rail 442 is installed below the mounting frame 441. A first guide column 443 is provided on the circular lifting rail 442. The end of the first guide column 443 away from the circular lifting rail 442 extends through the mounting frame 441. A pushing spring 444 is installed between the circular lifting rail 442 and the mounting frame 441. The interval floating mechanism 44 also includes a pushing protrusion 445 arranged inside the circular lifting rail 442. The pushing protrusion 445 is installed on the rotating shaft 42, and a resistance roller 446 is provided on the pushing protrusion 445.

[0040] When the rotating shaft 42 rotates, it will drive the pushing protrusion 445 to rotate synchronously. When the pushing protrusion 445 rotates upward, it will contact the roller 446 to move upward on the annular lifting rail 442. When the annular lifting rail 442 moves upward, it will squeeze the pushing spring 444. When the pushing protrusion 445 rotates downward, the contact roller 446 will disengage from the annular lifting rail 442 to cancel the pushing of the pushing spring 444. The squeezing of the pushing spring 444 will push the annular lifting rail 442 to move downward. The lifting and lowering movement of the annular lifting rail 442 will simultaneously drive the telescopic mounting shaft 13 to move up and down. The pushing by the pushing protrusion 445 can effectively achieve interval pushing to avoid damage to the equipment caused by excessive lifting speed.

[0041] See also Figure 3 , Figure 8 and Fig. 9 As shown, the compression cleaning head 5 is provided with a plurality of flow inlet holes, a second guide column 52 is installed inside the flow inlet hole, the second guide column 52 is slidably connected with the flow inlet hole, a first movable blocking block 51 is provided on the second guide column 52, and a mounting slot is provided at the bottom of the compression cleaning head 5, a push cleaning block 53 is installed inside the mounting slot.

[0042] The first movable blocking block 51 is made of rubber. When the compression cleaning head 5 is pushed by the synchronous pushing mechanism 6, the compression cleaning head 5 will pressurize the inside of the pressure filter rail 2 to quickly discharge the internal sewage. When the sewage inside the pressure filter rail 2 is squeezed, the tail of the first movable blocking block 51 will be subject to pushing pressure due to the water pressure. The tail of the first movable blocking block 51 is bucket-shaped, which can effectively increase the pushing pressure. The second guide column 52 will guide the pushed first movable blocking block 51 to move accurately to the inlet hole. The first movable blocking block 51 will resist and block the inlet hole to ensure the squeezing force. When the structure 6 is pulled outward, the compression cleaning head will shrink and move toward the water storage chamber 11, and the water pressure inside the water storage chamber 11 will push the first movable blocking block 51 to move toward the pressure filter rail 2, so that the inlet hole of the compression cleaning head 5 is opened again, and the water inside the water storage chamber 11 can quickly flow into the pressure filter rail 2, forming a backflow push that can effectively increase the water outlet speed. When the compression cleaning head 5 is pushed back and forth by the synchronous pushing mechanism 6, the pushing cleaning block 53 will scrub the sewage filter layer 222 of the pressure filter rail 2, effectively preventing dirt from adhering to the surface of the sewage filter layer 222 and increasing its service life.

[0043] See also Figure 8 and Fig. 9 As shown, the pushing cleaning block 53 includes a clamping mounting block 531 , and a cleaning brush 532 and an elastic scraping edge 533 are provided at the bottom of the clamping mounting block 531 .

[0044] The snap-on mounting block 531 is used to snap-on and install in the mounting slot at the bottom of the compression cleaning head 5, which is convenient for the staff to disassemble and maintain. The elastic scraper edge 533 at the bottom of the snap-on mounting block 531 can effectively scrape off dirt when moving on the sewage filter layer 222. The cleaning brush 532 rubs against the sewage filter layer 222 to effectively scrub the sewage filter layer 222. Double cleaning can effectively ensure the cleaning effect.

[0045] See also Figure 3 and Figure 5 As shown, the synchronous pushing mechanism 6 includes a driving ring 61 installed on the telescopic mounting shaft 13, and the outer wall of the driving ring 61 is provided with an inclined groove 611. The synchronous pushing mechanism 6 also includes a synchronous driving frame 62 installed inside the water storage chamber 11. The inner wall position of the synchronous driving frame 62 is provided with a sliding ball, and the sliding ball is slidably connected to the inclined groove 611. The synchronous driving frame 62 is also provided with a plurality of driving inclined rails 621, and a plurality of pushing sliding blocks 63 are installed inside the driving inclined rails 621. The pushing sliding blocks 63 are each installed with an elastic connecting rod 64, and the end of the elastic connecting rod 64 away from the pushing sliding block 63 is connected to the compression cleaning head 5.

[0046] When the telescopic mounting shaft 13 moves up and down, it will drive the driving ring 61 to move up and down. When the driving ring 61 moves up and down, the inclined groove 611 will guide the sliding ball on the synchronous driving frame 62 to move. When the sliding ball moves, it can effectively promote the synchronous driving frame 62 to rotate. When the synchronous driving frame 62 rotates, the driving inclined rail 621 will drive multiple pushing sliding blocks 63 to move synchronously. When the pushing sliding block 63 moves, it will push the compression cleaning head 5 connected to it to move telescopically through multiple elastic connecting rods 64, effectively and synchronously pushing multiple compression cleaning heads 5 to move telescopically.

[0047] See also Figure 1 and Fig.10 As shown, the dirt collection box 7 is installed on the dirt recovery box 71 at the bottom of the water storage tank 1, and a third guide column 75 is installed at the liquid inlet of the dirt recovery box 71, and a second movable blocking block 74 is installed on the third guide column 75. The interior of the dirt recovery box 71 is provided with a plurality of inclined blocking filter plates 72, and a sedimentation filter rail 73 is installed at the bottom of the blocking filter plate 72. A liquid guide tube is installed at the bottom of the dirt collection box 7.

[0048] When the telescopic mounting shaft 13 moves up and down, it will push the squeezing bucket 14 to continuously move up and down. When the squeezing bucket 14 moves up and down, it will reflux and squeeze the sewage inside the water storage chamber 11. When the squeezing bucket 14 presses down the sewage inside the water storage chamber 11, the liquid inlet of the dirt collection box 7 is affected by the water pressure to open the liquid inlet of the second movable blocking block 74, so that the sewage at the bottom of the water storage chamber 11 will flow into the liquid inlet of the dirt collection box 7. When the sewage enters the dirt collection box 7, the sewage will pass through the flow-blocking filter plate 72 and the sedimentation filter The rail 73 is then discharged outward from the liquid guide pipe. When the sewage flows, the baffle filter plate 72 will guide the dirt in the sewage to fall onto the sedimentation filter rail 73. The baffle filter plate 72 can effectively prevent the falling dirt from floating up. When the extrusion bucket 14 rises, it is affected by the water pressure suction. At the same time, the second movable blocking block 74 has a certain buoyancy to block the liquid inlet of the dirt recovery box 71. The liquid inlet of the dirt recovery box 71 is blocked, and the sewage inside the dirt recovery box 71 cannot be discharged from the liquid inlet, thereby effectively recovering the dirt precipitated in the sewage.

[0049] The treatment process of the wastewater treatment equipment based on wastewater instantaneous backflow flushing and blocking prevention includes the following steps;

[0050] S1. The kinetic energy conversion mechanism 4 guides the sewage into the water storage chamber 11 of the water tank 1. When the sewage passes through the kinetic energy conversion mechanism 4, it drives the working end of the kinetic energy conversion mechanism 4 to perform lifting and lowering movements. When the working end of the kinetic energy conversion mechanism 4 moves, it drives the telescopic mounting shaft 13 to perform synchronous lifting and lowering movements.

[0051] S2. When the telescopic mounting shaft 13 moves up and down, it will drive the extrusion bucket 14 and the synchronous pushing mechanism 6 to move synchronously. When the extrusion bucket 14 moves up and down, it will squeeze the sewage in the water storage chamber 11, so that the sewage will quickly flow into the pressure filter rail 2 and the dirt collection box 7. When the synchronous pushing mechanism 6 moves, it will push multiple compression cleaning heads 5 to move repeatedly inside the pressure filter rail 2. When the compression cleaning head 5 pushes and moves into the pressure filter rail 2, the sewage entering the pressure filter rail 2 will be quickly filtered out, and the filtered sewage will enter the water outlet chamber 12. The water outlet chamber 12 will guide and transport the filtered sewage to the area to be treated. At the same time, the compression cleaning head 5 will also clean the filter area when moving in the pressure filter rail 2 to prevent dirt from adhering to the filter area of ​​the pressure filter rail 2.

[0052] S3. The dirt collection box 7 at the bottom of the water storage tank 1 is used to precipitate and collect dirt. The pressure detection cover 3 detects the water pressure inside each pressure filter rail 2 in real time. When the internal water pressure is too high, it means that the pressure filter rail 2 is blocked, and the pressure filter rail 2 is replaced and maintained in time.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
