Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an integrated sewage treatment device. Background Art

[0002] An integrated sewage treatment device integrates multiple sewage treatment processes in one system. It usually includes a physical treatment unit, a biological treatment unit, and a deep treatment unit. This integrated design can effectively remove pollutants such as suspended solids, organic matter, nitrogen, and phosphorus in sewage. When treating domestic sewage, larger impurities and sand grains can be removed through physical treatment, organic pollutants in the sewage are decomposed by biological treatment, and the water quality is further purified by deep treatment, so that the treated sewage meets the discharge standards. The sewage in the septic tank contains a large amount of impurities. After the sewage enters the device, it will pass through a pretreatment device, which can intercept larger solid impurities in the septic tank sewage, such as undecomposed toilet paper, hair, etc. And these intercepted impurities need to be cleaned regularly to prevent the grille from being blocked and affecting the normal flow of sewage.

[0003] During the process of treating septic tank sewage, sludge will be formed whether it is the excess sludge in the biological treatment link or the solid impurities intercepted in the pretreatment link. These sludges need to be collected and treated. For the dehydrated sludge, it can be disposed of by landfill, incineration, composting, etc. according to the actual situation to avoid secondary pollution.

[0004] A large amount of sludge will be generated during the sewage treatment process, especially in the biological treatment unit. If the sludge production cannot be effectively controlled, it will increase the burden of sludge treatment. At the same time, these sludges are prone to form a greater obstacle to the normal transmission of liquid on the solid-liquid separation net.

[0005] Since there are more pollutants in the septic tank, biological treatment needs to be used. An environment with high acidity or high alkalinity is not conducive to the growth of microorganisms, which is likely to result in low efficiency of the biological treatment step.

[0006] Therefore, the present application proposes an integrated sewage treatment device. Summary of the Invention

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When the cleaning block at the top of the movable push block, which is smaller than the filter holes of the third filter screen, is inserted into the filter holes, the spring inside the second double-directional push rod adjusts the movable push block to move upward at this time, causing the small particulate impurities in the filter holes to be pushed towards the upper surface of the third filter screen. Then, the small particulate impurities will be pushed to the side position of the telescopic push block. The first double-directional push rod drives the telescopic push block to push these small particulate impurities from the transmission rack into the auxiliary processing box for cleaning, thereby reducing the blockage of the deep treatment filter screen, improving the liquid flow, and the pushing of the telescopic push block helps the garbage accumulated on the surface to be collected by the auxiliary processing box, thus improving the solid-liquid separation efficiency;

[0023] 2. The gear set drives the first processing roller to rotate through the connected motor. And multiple first processing rollers convert a large amount of solid impurities into particles by rotating. Then, another gear set drives the second processing roller to rotate to further decompose the particles, thus facilitating the transportation and subsequent disposal of the sludge. For the dehydrated sludge, it is refined later, and these filter residues are used as organic fertilizers to avoid secondary pollution, and the sewage is recycled, truly achieving energy conservation, consumption reduction, environmental protection, and harmlessness, while creating recyclable and sustainable economic benefits;

[0024] 3. The second filter screen drives the fixed block and the auxiliary gear block to move downward along the spring telescopic rod. At this time, the auxiliary gear block rotates through the engagement of the rack block, causing the garbage on the second filter screen to fall to the third filter screen with less garbage, and then fall into the auxiliary processing box, completing the layering, thereby avoiding the same-layer garbage from being poured out obliquely together and easily getting stuck at the output port, which affects the separation effect of solid garbage, and at the same time improving the cleaning efficiency of the large garbage filter screen and reducing the blockage;

[0025] 4. The double-directional clamping rod drives the positioning slide rod to contract inward along the arc-shaped chute turntable and the straight chute turntable through the rotating arc-shaped track. At this time, the auxiliary stirring blade contacts the inner wall of the arc-shaped chute turntable and the groove wall where the straight chute turntable and the outer wall of the auxiliary stirring blade fit, causing the dirt on the surface of the auxiliary stirring blade to be scraped off, avoiding the fan blade for stirring the liquid medicine from remaining with too much dirt, which affects the sewage filtration quality of the subsequent transmission.

Detailed implementation mode

[0040] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] As Figures 1 - 5 shown, an integrated sewage treatment device proposed by the present invention includes a sewage suction and purification vehicle 1. A double-layer flat treatment component 2 is fixedly installed inside the sewage suction and purification vehicle 1. A sewage treatment separation tank component 3 is fixedly installed on one side of the double-layer flat treatment component 2. A pretreatment link 4 is opened at the top of the sewage treatment separation tank component 3. A physical treatment unit 5 is opened in the middle of the sewage treatment separation tank component 3. A deep treatment unit 6 is opened at the bottom of the sewage treatment separation tank component 3;

[0042] The sewage suction and purification vehicle 1 includes a transport outer frame 101 fixedly installed outside the auxiliary separation tank 301. The transport outer frame 101 can be installed on a transport vehicle and drive to different septic tanks to treat sewage. A sewage tank 102 is fixedly installed at the top of the transport outer frame 101. A water circulation tank 105 is fixedly installed at the bottom of the sewage tank 102. An aeration component 103 is fixedly installed on one side of the sewage tank 102. The auxiliary separation tank 301 is fixedly installed on the output shaft of the sewage tank 102. An automatic medicine mixing tank 104 is fixedly installed outside the auxiliary separation tank 301. The sewage from the septic tank is transported into the sewage tank 102 in the integrated sewage treatment device through a pipeline for preliminary storage. In this process, the pipeline is laid with a certain slope to ensure that the sewage can flow smoothly into the sewage tank 102 by the action of gravity. In the sewage tank 102, air is filled into the sewage through the aeration component 103 connected to the sewage tank 102. The microorganisms in the activated sludge use the organic matter in the sewage as a nutrient source for growth and reproduction, and at the same time decompose the organic matter. The water circulation tank 105 gives a certain amount of neutral water flow in the sewage tank 102 to avoid excessive acidity or alkalinity in the sewage tank 102 from affecting the survival of microorganisms. Then, a quantitative amount of sewage material is introduced into the auxiliary separation tank 301 by using a water pump component. The chlorine dioxide transmitted by the automatic medicine mixing tank 104 in the auxiliary separation tank 301 disinfects the sewage through its strong oxidizing property to ensure the microbial safety of the effluent and meet the discharge standard. At the same time, a third filter screen 501 is also used to filter it to further remove the suspended matter in the sewage

[0043] As Figures 1 - 4As shown in the figure, the double-layer flat plate processing component 2 includes an auxiliary processing box 202 fixedly installed on the transportation outer frame 101. The auxiliary processing box 202 and the auxiliary separation tank 301 are connected in a communicating state through a transmission frame 302. The double-layer flat plate processing component 2 also includes a fertilizer raw material conveying frame 201 fixedly installed on the side away from the auxiliary separation tank 301. Two groups of gear sets 206 are rotatably installed on the side of the auxiliary processing box 202. One group of gear sets 206 passes through one side of the auxiliary processing box 202 and is fixedly installed with a first processing roller 203. The other group of gear sets 206 passes through one side of the auxiliary processing box 202 and is fixedly installed with a second processing roller 205. A hydraulic push pump 204 is fixedly installed on the side of the auxiliary processing box 202 facing the fertilizer raw material conveying frame 201. An automatic opening and closing door is provided at the connection between the transmission frame 302 and the hydraulic push pump 204. When the automatic opening and closing door is opened, the auxiliary separation tank 301 is tilted by the push of the hydraulic push pump 204, and the solid impurities in the auxiliary separation tank 301 enter the interior of the auxiliary processing box 202. Then, the moisture content of the sludge is further reduced through the double-layer flat plate processing component 2. The gear sets 206 drive the first processing roller 203 to rotate through the connected motor, and a large number of solid impurities are converted into particles by the rotation of the multiple first processing rollers 203. Then, another group of gear sets 206 drives the second processing roller 205 to rotate to further decompose the particles, which facilitates the transportation and subsequent disposal of the sludge. For the dehydrated sludge, post-treatment refining is carried out, and these filter residues are used as organic fertilizers to avoid secondary pollution and realize the recycling of sewage. It truly realizes energy conservation, consumption reduction, environmental protection, and harmlessness, and at the same time creates a recyclable and sustainable economic benefit.

[0044] As Figures 1 - 13As shown in the figure, the sewage treatment separation tank assembly 3 includes an auxiliary separation tank 301. At the top of the auxiliary separation tank 301, a first hollow rotating rod 303 is installed through a first motor. At the bottom of the first hollow rotating rod 303, a spring positioning rod 304 is slidably installed. On one side of the auxiliary separation tank 301, a transmission rack 302 is fixedly installed. The pretreatment link 4 includes two first filter meshes 401 slidably installed on the inner wall of the auxiliary separation tank 301. In the middle of the auxiliary separation tank 301, a second filter mesh 402 is slidably installed, and the second filter mesh 402 is located between the two first filter meshes 401. The two first filter meshes 401 and the second filter mesh 402 are in an overall filtering state under normal conditions and are adsorbed to each other by electromagnetic force, which can intercept larger solid impurities in the septic tank sewage, such as undecomposed toilet paper, hair, etc. At the connection between the first filter mesh 401, the second filter mesh 402 and the auxiliary separation tank 301, a chute is provided. At the connection between the first filter mesh 401, the second filter mesh 402 and the chute, a telescopic corrugated block 404 is fixedly installed. Inside the chute where the second filter mesh 402 is located, a fixed block is rotatably installed. The fixed block is slidably installed inside the chute, and a spring telescopic rod 406 is fixedly installed between the fixed block and the chute. On the outside of the second filter mesh 402, an auxiliary gear block 405 is fixedly installed. Inside the chute, a rack block 403 is fixedly installed. The rack block 403 and the auxiliary gear block 405 are arranged in a meshing state. There is a pressure sensing component inside the spring telescopic rod 406. When the second filter mesh 402 for filtering large garbage and the first filter mesh 401 slide down along the chute of the auxiliary separation tank 301 together after filtering large garbage, when the pressure sensor inside the spring telescopic rod 406 senses a specified pressure, the sewage transmission in the sewage tank 102 stops, and the electromagnetic suction between the first filter mesh 401 and the second filter mesh 402 ends. If the two first filter meshes 401 carry too much dirt, the two first filter meshes 401 move down along the corresponding chutes. Due to gravity and the inclination of the auxiliary separation tank 301, these solid garbage flow into the sewage tank 102 along the transmission rack 302. If there is too much garbage on the second filter mesh 402, relying on the difference in the garbage weight carried between the second filter mesh 402 and the two first filter meshes 401, the garbage on the first filter mesh 401 on the side far from the transmission rack 302 is likely to fall onto the second filter mesh 402, resulting in an easier generation of a load-bearing error between the two. Then there are gaps on both sides of the second filter mesh 402. The second filter mesh 402 drives the fixed block and the auxiliary gear block 405 to move down along the spring telescopic rod 406. At this time, the auxiliary gear block 405 rotates through the meshing with the rack block 403, causing the garbage on the second filter mesh 402 to fall to the third filter mesh 501 with less garbage, and then fall into the auxiliary processing box 202, completing the layering and thus avoiding the same-layer garbage from being poured out obliquely together and easily jamming the output port, thereby affecting the separation effect of solid garbage and at the same time improving the cleaning efficiency of the large garbage filter mesh.Reduce blockage.,

[0045] As Figures 5 - 11 shown, the physical processing unit 5 further includes a straight chute turntable 514 fixedly installed at the bottom of the spring positioning rod 304. Inside the straight chute turntable 514, the same number of auxiliary stirring blades 515 are slidably installed through a plurality of positioning slide rods 502. On both the upper and lower sides of the positioning slide rod 502, two groups of bidirectional engaging rods 510 are fixedly installed. At the bottom of the straight chute turntable 514, an arc chute turntable 508 is rotatably installed. The two groups of bidirectional engaging rods 510 are respectively slidably installed inside the straight chute turntable 514 and the arc chute turntable 508. On one side of both the straight chute turntable 514 and the arc chute turntable 508, a shielding block is fixedly installed. On the side of the arc chute turntable 508 facing the second hollow rotating rod 601, an electromagnetic component is fixedly installed. When the first filter screen 401 moves downward under a large gravity, the first filter screen 401 drives the spring positioning rod 304 to move downward along the inside of the first hollow rotating rod 303, and the spring positioning rod 304 moves downward along the inside of the second hollow rotating rod 601. And a spring for restoring the original position is installed at the connection between the spring positioning rod 304 and the first hollow rotating rod 303. When the bottom of the arc chute turntable 508 contacts the top of the second hollow rotating rod 601, the bottom of the arc chute turntable 508 is electromagnetically adsorbed by the second hollow rotating rod 601. At this time, the second hollow rotating rod 601 drives the arc chute turntable 508 to rotate forward, then the bidirectional engaging rod 510 drives the positioning slide rod 502 to contract inward along the arc chute turntable 508 and the straight chute turntable 514 through the rotating arc track. At this time, the auxiliary stirring blade 515 contacts the inner wall of the arc chute turntable 508 and the groove wall of the straight chute turntable 514 that fits the outer wall of the auxiliary stirring blade 515, causing the residual dirt on the surface of the auxiliary stirring blade 515 to be scraped off, avoiding too much dirt remaining on the fan blades for stirring the liquid medicine, and thus affecting the sewage filtration quality of the subsequent transmission;

[0046] Then the second hollow rotating rod 601 drives the arc chute turntable 508 to rotate in the reverse direction, reset the 608 and turn off the function of the electromagnetic component at the top of the second hollow rotating rod 601, and the first filter screen 401 will be reset by the spring in the first hollow rotating rod 303.

[0047] In this embodiment, the physical processing unit 5 includes a third filter screen 501 fixedly installed on the inner wall of the auxiliary separation tank 301. Two groups of limiting gear blocks 513 are rotatably installed on both sides of the third filter screen 501. A bidirectional guiding sliding disc 509 is meshed and connected to the outside of the limiting gear blocks 513 through a plurality of gear blocks 512. Auxiliary springs 511 are fixedly installed on both sides of the bidirectional guiding sliding disc 509. The number of the bidirectional guiding sliding discs 509 is two. A plurality of first bidirectional pushing long rods 503 are fixedly installed on the top of the bidirectional guiding sliding disc 509 located at the top of the third filter screen 501. A telescopic pushing block 504 is slidably installed at the bottom of the first bidirectional pushing long rod 503 through the auxiliary spring 511. A plurality of second bidirectional pushing long rods 507 are fixedly installed on the bottom of the bidirectional guiding sliding disc 509 located at the third filter screen 501. A plurality of built-in spring tubes 506 are fixedly installed on the side of the second bidirectional pushing long rod 507 facing the third filter screen 501. A movable pushing block 505 is slidably installed inside the built-in spring tube 506. A plurality of cleaning blocks adapted to the filter holes of the third filter screen 501 are fixedly installed on the side of the movable pushing block 505 facing the third filter screen 501;

[0048] The deep processing unit 6 includes a second hollow rotating rod 601 installed at the bottom of the auxiliary separation tank 301 through a second motor. A stirring block 602 is fixedly installed on the outer side of the second hollow rotating rod 601. Two limiting gear blocks 513 are fixedly installed at the top of the auxiliary separation tank 301. A spring positioning rod 304 is rotatably installed inside the second hollow rotating rod 601. The second hollow rotating rod 601 rotates by connecting to the second motor, and the second motor is a forward and reverse motor. The second hollow rotating rod 601 drives the stirring block 602 to cooperate with the auxiliary stirring blade 515 to stir and mix the drugs transmitted by the automatic medicine mixing tank 104. During this process, the second hollow rotating rod 601 rotates under the limitation of two auxiliary springs 511. The limiting gear block 513 drives the two-way guiding sliding plate 509 to perform reciprocating motion within a specified range through the meshing of the gear block 512 and the auxiliary spring 511. The second two-way pushing long rod 507 located below the third filter screen 501 drives the built-in spring tube 506 and the movable push block 505 to slide along the filter holes below the third filter screen 501. When the cleaning block on the top of the movable push block 505 that is smaller than the filter holes of the third filter screen 501 is inserted into the filter holes, at this time, the spring in the second two-way pushing long rod 507 adjusts the movable push block 505 to move upward, pushing the small particle impurities in the filter holes to the upper surface of the third filter screen 501. Since the second two-way pushing long rod 507 and the first two-way pushing long rod 503 are cross-arranged, the small particle impurities will be pushed to the side position of the telescopic pushing block 504, preventing the first two-way pushing long rod 503 from driving the telescopic pushing block 504 to push these small particle impurities from the transmission rack 302 into the auxiliary processing box 202 for cleaning, thereby reducing the blockage of the deep processing filter screen, improving the liquid flow, and the pushing of the telescopic pushing block 504 helps the garbage accumulated on the surface to be collected by the auxiliary processing box 202, thus improving the solid-liquid separation efficiency.
