Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sewage treatment equipment, and specifically relates to an automated sewage treatment equipment for municipal engineering. Background Art
[0002] In the field of municipal engineering, sewage treatment is a key link to ensure the urban environmental quality and sustainable utilization of water resources; with the rapid development of cities and the continuous growth of the population, the generation amount of municipal sewage is increasing day by day, and the sewage composition is becoming more and more complex, which puts higher requirements on sewage treatment equipment.
[0003] However, many problems have emerged in the actual application of traditional municipal engineering sewage treatment equipment. In the pretreatment stage, the commonly used coarse grille has a simple structure and can only preliminarily intercept larger impurities in the sewage; moreover, after long-term use, a large amount of impurities are easily adhered to the surface of the coarse grille, resulting in the blockage of the grille holes, which not only affects the interception effect, but also greatly reduces the sewage throughput and the sewage treatment efficiency; at the same time, the existing coarse grille usually has a fixed mesh number and is difficult to be flexibly replaced according to different sewage water qualities and treatment requirements, and the applicability of the equipment is poor; The stability of the salvage structure of traditional equipment is poor. During the salvage process, the salvage plate is easy to shake, which not only affects the accuracy of impurity salvage, but also may cause the intercepted impurities to fall back into the sewage again, reducing the interception effect. In addition, the cleaning work of the salvaged impurities is also more cumbersome, often requiring manual cleaning, which consumes a large amount of manpower and time costs; For the treatment of the salvaged impurities, most traditional equipment lacks effective means of compression and volume reduction. The impurities have a large volume and high water content, which not only increases the difficulty of subsequent transportation and treatment, but also occupies a large amount of storage space. Moreover, in the impurity transfer link, the traditional method usually requires shutdown for operation, which further reduces the overall efficiency of sewage treatment and cannot meet the continuous demand of municipal sewage treatment.

Detailed implementation manners
[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, a municipal engineering automatic sewage treatment device described in the present invention includes a treatment tank 1, a pretreatment structure 2 arranged inside the treatment tank 1, a salvage structure 3 arranged on the pretreatment structure 2, a cleaning structure 4 arranged on the salvage structure 3, an installation structure 5 arranged on the salvage structure 3, a compression structure 6 arranged on the salvage structure 3, and a transfer structure 7 arranged on one side of the treatment tank 1; The pretreatment structure 2 includes a retaining wall 201 and a coarse grille 202 installed on the retaining wall 201, and the retaining wall 201 is fixedly connected to the inside of the treatment tank 1; The salvage structure 3 includes a first screw rod 301 and a first motor 302 fixedly connected to the retaining wall 201. The first screw rod 301 is rotatably connected to the retaining wall 201. Two lifting bars 303 are slidably connected to the retaining wall 201. Two connecting bars 305 are fixedly connected between the two lifting bars 303. The first screw rod 301 is threadedly connected to one of the lifting bars 303. The bottom ends of the two lifting bars 303 are fixedly connected with a salvage plate 304. The cross section of the lifting bar 303 is a Z-shaped structure. The salvage plate 304 is inclined. A guide rod 306 is fixedly connected to the retaining wall 201. The other lifting bar 303 is slidably connected to the guide rod 306; One side of the treatment tank 1 is fixedly connected with a water inlet pipe 203. The other side of the treatment tank 1 is fixedly connected with a plurality of water outlet pipes 204; Sewage flows into the treatment tank 1 through the water inlet pipe 203. At this time, the pretreatment structure 2 treats large-volume sundries in the sewage. When the sewage flows through the coarse grille 202 on the retaining wall 201, the coarse grille 202 will intercept large-particle impurities in the sewage, such as branches, plastic bottles, etc., and initially purify the sewage to prevent these large-particle impurities from damaging or blocking the subsequent treatment equipment. The intercepted sewage enters the subsequent sewage treatment equipment. After intercepting larger garbage, the first motor 302 is started. The first motor 302 drives the first screw rod 301 to rotate. Since the first screw rod 301 is threadedly connected to one of the lifting bars 303 and the other lifting bar 303 is slidably connected to the guide rod 306, when the first screw rod 301 rotates, the two lifting bars 303 will move up and down along the directions of the guide rod 306 and the first screw rod 301. The salvage plate 304 fixedly connected to the lifting bar 303 moves accordingly. The salvage plate 304 is inclined. During the descending process, it will press down on the floating objects. However, due to the inclined surface design, the floating objects will re-float to the water surface under the action of buoyancy and be intercepted by the coarse grille 202. At the same time, the inclined setting of the salvage plate 304 can better contact and pick up the impurities intercepted by the coarse grille 202. When the salvage plate 304 rises to a certain height, the picked-up impurities can be compressed and subsequent treatment can be carried out.
[0023] Specifically, such as Figure 6 and Figure 11As shown, the cleaning structure 4 includes a slide bar 401 and a fixed block 402 fixedly connected to the fishing plate 304. The slide bar 401 is slidably connected inside the fishing plate 304. A second screw rod 403 is rotatably connected to the fixed block 402. The second screw rod 403 is threadedly connected to the slide bar 401. A wire brush 405 is fixedly connected to the slide bar 401. A plurality of guide shafts 404 are fixedly connected to the fishing plate 304. The slide bar 401 is slidably connected to the guide shafts 404. When the coarse grille 202 has been used for a period of time, the coarse grille 202 can be cleaned. When cleaning the impurities on the coarse grille 202, the second screw rod 403 can be rotated. The second screw rod 403 is threadedly connected to the slide bar 401, and the slide bar 401 is slidably connected to the guide shafts 404. Therefore, when the second screw rod 403 rotates, the slide bar 401 will slide inside the fishing plate 304 along the guide shafts 404, and the wire brush 405 fixed to the slide bar 401 will move accordingly. At this time, the wire brush 405 is in close contact with the coarse grille 202. Then, in cooperation with the lifting structure 3 to drive the fishing plate 304 to rise and fall, the impurities adhering to the coarse grille 202 can be brushed off.
[0024] Specifically, such as Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, the mounting structure 5 includes a clamping strip 501 and a clamping slot 502. The interior of the barrier wall 201 is slidably connected with two clamping strips 501. The coarse grid 202 is symmetrically provided with two clamping slots 502. The clamping strips 501 are engaged with the clamping slots 502. The interior of the barrier wall 201 is fixedly connected with a plurality of fixing rods 503. The outer sleeve of the fixing rod 503 is provided with a spring 504. The two ends of the spring 504 are respectively fixedly connected to the barrier wall 201 and the clamping strip 501. The barrier wall The interior of the 201 is slidably connected to a lifting bar 506, and two inclined grooves 507 are symmetrically arranged on the lifting bar 506. A driving shaft 505 is fixedly connected to the clamping bar 501, and the driving shaft 505 is slidably connected to the inclined groove 507. A pressing rod 508 is fixedly connected to the lifting bar 506, and the pressing rod 508 is slidably connected to the wall 201. A rotating shaft 509 is rotatably connected to the coarse grid 202, and a handle 509 with a U-shaped cross section is fixedly connected to the rotating shaft 509. 10; When it is necessary to replace the coarse grid 202 with a different mesh number, the pressing rod 508 can be pressed upward, and the pressing rod 508 drives the lifting bar 506 to move upward. The inclined groove 507 on the lifting bar 506 is slidably connected with the driving shaft 505 on the clamping bar 501. When the lifting bar 506 rises, the driving shaft 505 moves along the inclined groove 507, so that the clamping bar 501 slides away from the clamping groove 502, thereby loosening the coarse grid 202. At this time, the rotating shaft 509 can be rotated to The handle 510 can be used to conveniently take out the coarse grille 202, and a new coarse grille 202 can be replaced at this time. When installing the coarse grille 202, align the slot 502 on the coarse grille 202 with the clamping strip 501 in the retaining wall 201, and then push the coarse grille 202. The clamping strip 501 is clamped into the slot 502 under the action of the spring 504, so that the coarse grille 202 is installed. Then, the handle 510 is turned to make it fit into the groove at the retaining wall 201 so that it does not affect the operation of the salvage structure 3.
[0025] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the compression structure 6 includes a fixing frame 601 and a first hydraulic rod 602 fixedly connected to the fixing frame 601. The fixing frame 601 is fixedly connected to the retaining wall 201. The extending end of the first hydraulic rod 602 is fixedly connected to a fixing strip 603. A pushing plate 604 is fixedly connected to the fixing strip 603. A feeding chute 605 is fixedly connected to the treatment tank 1. A second hydraulic rod 606 is fixedly connected to the feeding chute 605. The telescopic end of the second hydraulic rod 606 is fixedly connected to a connecting rod 607. A feeding plate 608 is fixedly connected to the connecting rod 607. The feeding plate 608 is slidably connected to the feeding chute 605. A fixing frame 609 is fixedly connected to the treatment tank 1. An extruder housing 610 is fixedly connected to the fixing frame 609. The end of the feeding chute 605 is fixedly connected to the extruder housing 610. A second motor 611 is fixedly connected to the top of the extruder housing 610. An extrusion paddle 612 is rotatably connected to the inside of the extruder housing 610. The output end of the second motor 611 is fixedly connected to the extrusion paddle 612. The bottom cross-section of the extrusion paddle 612 is trapezoidal in structure.
[0026] The transfer structure 7 includes two blanking pipes 701 and a fixing plate 702 fixedly connected to the treatment tank 1. The bottom end of the extruder housing 610 is fixedly connected with two blanking pipes 701. There are two sliding grooves 703 on the fixing plate 702. A baffle 704 is slidably connected to the sliding grooves 703, and the baffle 704 abuts against the bottom end of the blanking pipe 701. A slide rail 705 is fixedly connected to the open space on one side of the treatment tank 1. Above the slide rail 705, there are two transfer trolleys 706. The bottom end of the transfer trolley 706 is fixedly connected with a sliding sleeve 707, and the sliding sleeve 707 is slidably connected to the slide rail 705. A resisting block 708 is fixedly connected to the transfer trolley 706, and the resisting block 708 abuts against the baffle 704. After the fished impurities rise to a certain height, the first hydraulic rod 602 is started. The first hydraulic rod 602 extends, driving the fixing strip 603 and the pushing plate 604 to move, and pushing the impurities towards the blanking chute 605. At the same time, the second hydraulic rod 606 is started. The telescopic end of the second hydraulic rod 606 drives the connecting rod 607 and the blanking plate 608 to slide in the blanking chute 605, opening the channel from the blanking chute 605 to the extruder housing 610, so that the impurities enter the extruder housing 610. Then, the second motor 611 is started. The second motor 611 drives the extrusion paddle 612 to rotate. The bottom end of the extrusion paddle 612 is trapezoidal in structure, and the impurities are extruded during the rotation process, realizing the compression and volume reduction of the impurities, which is convenient for subsequent treatment. The compressed impurities are discharged through the blanking pipe 701 at the bottom end of the extruder housing 610. At this time, the transfer trolley 706 is pushed. The transfer trolley 706 slides on the slide rail 705 through the sliding sleeve 707. The resisting block 708 on the transfer trolley 706 will push the baffle 704, causing the baffle 704 to slide in the sliding groove 703 of the fixing plate 702, opening the bottom channel of the blanking pipe 701. At the same time, the baffle 704 will block the other blanking pipe 701. The compressed impurities fall into the transfer trolley 706 from the opened blanking pipe 701. When one transfer trolley 706 is full, the other transfer trolley 706 can be pushed. The resisting block 708 on the other transfer trolley 706 will push the baffle 704 to block the blanking pipe 701 that is discharging materials, and the channel of the blanking pipe 701 that has not discharged materials before is opened. The newly compressed impurities enter the empty transfer trolley 706. Then, the full transfer trolley 706 can be pushed away for subsequent transportation and treatment.
[0027] When the present invention is in use, first, sewage flows into the treatment tank 1 through the water inlet pipe 203. At this time, the pretreatment structure 2 treats large-volume sundries in the sewage. When the sewage flows through the coarse grille 202 on the retaining wall 201, the coarse grille 202 intercepts large-particle impurities in the sewage, such as branches, plastic bottles, etc., initially purifying the sewage to prevent these large-particle impurities from damaging or blocking subsequent treatment equipment. The intercepted sewage enters the subsequent sewage treatment equipment through the water outlet pipe 204. After intercepting larger garbage, the first motor 302 is started, and the first motor 302 drives the first screw 301 to rotate. Since the first screw 301 is threadedly connected to one of the lifting bars 303, and the other lifting bar 303 is slidably connected to the guide rod 306, when the first screw 301 rotates, the two lifting bars 303 will move up and down along the directions of the guide rod 306 and the first screw 301, and the fishing plate 304 fixedly connected to the lifting bar 303 moves accordingly. The fishing plate 304 is inclined. During the descending process, it will press down on floating objects, but due to the inclined surface design, the floating objects will re-float to the water surface under the action of buoyancy and be intercepted by the coarse grille 202. At the same time, the inclined setting of the fishing plate 304 can better contact and pick up the impurities intercepted on the coarse grille 202. When the fishing plate 304 rises to a certain height, the picked-up impurities can be compressed and subjected to subsequent treatment; Then, when the coarse grille 202 is used for a period of time, the coarse grille 202 can be cleaned. When cleaning the impurities on the coarse grille 202, the second screw 403 can be rotated. The second screw 403 is threadedly connected to the slide bar 401, and the slide bar 401 is slidably connected to the guide shaft 404. Therefore, when the second screw 403 rotates, the slide bar 401 will slide inside the fishing plate 304 along the guide shaft 404, and the wire brush 405 fixed to the slide bar 401 moves accordingly. At this time, the wire brush 405 is in close contact with the coarse grille 202, and then in cooperation with the lifting structure 3 to drive the fishing plate 304 to rise and fall, thereby brushing off the impurities adhering to the coarse grille 202; Secondly, when it is necessary to replace the coarse grille 202 with different mesh numbers, the pressing rod 508 can be pressed upward. The pressing rod 508 drives the lifting bar 506 to move upward. The inclined groove 507 on the lifting bar 506 is slidably connected to the driving shaft 505 on the clamping bar 501. During the upward movement of the lifting bar 506, the driving shaft 505 will move along the inclined groove 507, causing the clamping bar 501 to slide away from the clamping groove 502, thereby loosening the coarse grille 202. At this time, the coarse grille 202 can be conveniently taken out by turning the handle 510 on the rotating shaft 509. At this time, a new coarse grille 202 can be replaced. When installing the coarse grille 202, align the clamping groove 502 on the coarse grille 202 with the clamping bar 501 in the retaining wall 201, and then push the coarse grille 202. The clamping bar 501 is snapped into the clamping groove 502 under the action of the spring 504 to complete the installation of the coarse grille 202. Then turn the handle 510 to make it retract into the groove at the retaining wall 201 so as not to affect the operation of the fishing structure 3; Finally, after the fished impurities rise to a certain height, the first hydraulic rod 602 is activated. The first hydraulic rod 602 extends, driving the fixed strip 603 and the push plate 604 to move, and pushing the impurities towards the material chute 605. At the same time, the second hydraulic rod 606 is activated. The telescopic end of the second hydraulic rod 606 drives the connecting rod 607 and the material discharging plate 608 to slide in the material chute 605, opening the passage from the material chute 605 to the extruder housing 610, so that the impurities enter the extruder housing 610. Then, the second motor 611 is activated. The second motor 611 drives the extrusion paddle 612 to rotate. The bottom end of the extrusion paddle 612 is trapezoidal in structure, and the impurities are extruded during the rotation process, realizing the compression and volume reduction of the impurities, which is convenient for subsequent treatment. The compressed impurities are discharged through the material discharging pipe 701 at the bottom of the extruder housing 610. At this time, the transfer trolley 706 is pushed. The transfer trolley 706 slides on the slide rail 705 through the sliding sleeve 707. The abutting block 708 on the transfer trolley 706 will push the baffle plate 704, causing the baffle plate 704 to slide in the chute 703 of the fixed plate 702, opening the bottom channel of the material discharging pipe 701. At the same time, the baffle plate 704 will block another material discharging pipe 701. The compressed impurities fall into the transfer trolley 706 from the opened material discharging pipe 701. When one transfer trolley 706 is full, another transfer trolley 706 can be pushed. The abutting block 708 on the other transfer trolley 706 will push the baffle plate 704 to block the material discharging pipe 701 that is discharging materials, and the channel of the material discharging pipe 701 that has not discharged materials before is opened. The newly compressed impurities enter the empty transfer trolley 706. Then, the full transfer trolley 706 can be pushed away for subsequent transportation and treatment.
