Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sewage treatment of water conservancy facilities, and specifically relates to a classified sewage recovery device for water conservancy facilities. BACKGROUND

[0002] Water conservancy engineering is a facility for controlling and regulating surface water and groundwater in nature, controlling, regulating, developing, utilizing and protecting water in nature, to reduce and avoid water disasters, and to utilize water resources to meet the needs of human society and the natural environment. At present, when water conservancy sewage is recovered and utilized, a classification device is often needed to pre-classify and treat the sewage to separate solid impurities from the sewage, so as to ensure the subsequent treatment effect of the sewage.

[0003] In the prior art, when the classification device classifies and treats the sewage, a filter screen is often used to filter the sewage to separate solid impurities from the sewage. In order to prevent the filter screen from being blocked due to too many solid impurities on one side of the filter screen, thereby affecting the filtering efficiency of the subsequent sewage, some classification devices also include a scraping mechanism that moves along the surface of the filter screen to scrape off the solid impurities from the surface of the filter screen. However, during the scraping process of the scraping mechanism, the filter screen will generate a large friction force on the solid impurities, making it difficult to scrape off the solid impurities smoothly, and the solid impurities will also damage the filter screen during the scraping process, causing the filter screen to be damaged and the mesh size to increase, thereby affecting the filtering effect of the subsequent sewage. SUMMARY

After entering the tank, the wastewater passes through the filtration assembly from top to bottom. At this time, impurities in the wastewater are intercepted at the top of the filtration assembly, thereby achieving the separation of wastewater and impurities. In the above process, the first driving component drives the adsorption piston assembly to move back and forth along the top of the filtration assembly. When the adsorption piston assembly moves to the right along the top of the filtration assembly, the second driving component drives the adsorption piston assembly to move upward, thereby adsorbing the impurities intercepted at the top of the filtration assembly. The adsorption piston assembly moves the adsorbed debris to the right. When the adsorption piston assembly is removed from the upper area of ​​the water filter assembly, the second drive assembly moves the adsorption piston assembly downward, thereby releasing the adsorption of the debris and discharging the debris to the right side of the water filter assembly.

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please see Figure 1 as well as Figure 2 This embodiment provides a wastewater classification and recycling device for water conservancy facilities, including a housing 10, a piston-type adsorption assembly 20, a first driving assembly 30, a water filtration assembly 40, and a second driving assembly 50. The housing 10 has a water inlet 101 at its top. The water filtration assembly 40 is fixedly installed inside the housing 10 and located below the water inlet 101 for filtering wastewater. The piston-type adsorption assembly 20 is positioned above the water filtration assembly 40. The first driving assembly 30 is installed on the side wall of the housing 10 for driving the piston-type adsorption assembly. The piston adsorption assembly 20 moves back and forth along the upper part of the water filter assembly 40. The second drive assembly 50 is disposed on the inner wall of the housing 10. When the piston adsorption assembly 20 moves to the right along the upper part of the water filter assembly 40, the second drive assembly 50 is used to drive the piston adsorption assembly 20 to move upward to adsorb the impurities intercepted on the upper part of the water filter assembly 40. When the piston adsorption assembly 20 is removed to the right from the upper part of the water filter assembly 40, the second drive assembly 50 is used to drive the piston adsorption assembly 20 to move downward to release the adsorption state of the impurities.

[0035] When it is necessary to recycle and reuse wastewater, the wastewater inlet 101 can be introduced into the tank 10. After the wastewater enters the tank 10, it passes through the filter water assembly 40 from top to bottom. At this time, the impurities in the wastewater are intercepted on the upper part of the filter water assembly 40, thereby achieving the separation of wastewater and impurities. In the above process, the first drive assembly 30 drives the adsorption piston assembly 20 to move back and forth along the upper part of the filter water assembly 40. When the adsorption piston assembly 20 moves to the right along the upper part of the filter water assembly 40, the second drive assembly 50 drives the adsorption piston assembly 20 to move upward, thereby adsorbing the impurities intercepted on the upper part of the filter water assembly 40. The adsorption piston assembly 20 moves the adsorbed impurities to the right. When the adsorption piston assembly 20 is removed from the upper part of the filter water assembly 40, the second drive assembly 50 drives the adsorption piston assembly 20 to move downward, thereby releasing the adsorption state of the impurities and unloading the impurities to the right side of the filter water assembly 40, thereby achieving automatic cleaning of the impurities on the upper part of the filter water assembly 40.

[0036] Please see Figure 1 In one embodiment, the water filtration assembly 40 includes a frame 401 and a filter screen 402 fixedly embedded inside the frame 401, the frame 401 being fixedly installed on the inner wall of the housing 10.

[0037] After the sewage enters the tank 10 through the inlet 101, the sewage passes through the filter screen 402 from top to bottom. The impurities in the sewage are intercepted on the upper part of the filter screen 402, thus achieving the separation of sewage and impurities.

[0038] Please see Figure 1 as well as Figure 3 In one embodiment, the adsorption piston assembly 20 includes a transfer box 201, a piston plate 205, and a partition net 206. The transfer box 201 is disposed above the frame 401, and the bottom of the transfer box 201 is open. The partition net 206 is fixedly disposed inside the transfer box 201, and the piston plate 205 is movably disposed inside the transfer box 201 and located in the area above the partition net 206.

[0039] The first drive assembly 30 drives the transfer box 201, piston plate 205, and partition screen 206 to move back and forth along the upper part of the frame 401. When the transfer box 201, piston plate 205, and partition screen 206 move to the right, the second drive assembly 50 drives the piston plate 205 to move upward along the inside of the transfer box 201, thereby drawing air from the frame 401 and below the filter screen 402 into the transfer box 201. During this process, the air passes through the filter screen 402 from bottom to top, thereby removing debris trapped on the upper part of the filter screen 402. As the debris enters the transfer box 201, it acts on the bottom of the partition 206, thus adsorbing the debris. When the transfer box 201, piston plate 205, and partition 206 are removed to the right from the area above the frame 401, the second drive assembly 50 drives the piston plate 205 to move downward along the inside of the transfer box 201. At this time, the piston plate 205 presses the air inside the transfer box 201, so that the air passes through the partition 206 from top to bottom, thereby blowing away the debris at the bottom of the partition 206, thus completing the unloading of the debris.

[0040] Please see Figure 1 as well as Figure 2 In one embodiment, a discharge port 103 is provided on the right side wall of the box 10, and a guide plate 403 is fixedly provided on the right end of the frame 401. The guide plate 403 is arranged at an angle, and the end of the guide plate 403 away from the frame 401 extends to the bottom of the discharge port 103.

[0041] When the second drive assembly 50 drives the piston plate 205 to move downward along the inside of the transfer box 201, the piston plate 205 drives the air inside the transfer box 201 to pass through the partition 206 from top to bottom, thereby blowing away the debris at the bottom of the partition 206. The blown-away debris falls onto the upper surface of the guide plate 403, then slides from the upper surface of the guide plate 403 to the debris discharge port 103, and finally is discharged through the debris discharge port 103.

[0042] Please see Figure 1 as well as Figure 3 In one embodiment, two sets of sliders 207 are fixedly disposed on the side wall of the transfer box 201. The first drive assembly 30 includes a motor (not shown in the figure), a lead screw 301, and a guide rod 302. The motor is fixedly installed on the outer wall of the box 10. One end of the lead screw 301 is connected to the output end of the motor, and the other end extends into the interior of the box 10 and passes through one set of sliders 207. The lead screw 301 is threadedly engaged with the corresponding slider 207. The guide rod 302 is fixedly installed on the inner wall of the box 10. The guide rod 302 passes through the other set of sliders 207 and slides with the other set of sliders 207.

[0043] The motor drives the lead screw 301 to rotate in both directions. When the lead screw 301 rotates in the forward direction, the screw 301 and the corresponding slider 207 are engaged by a threaded connection, and the guide rod 302 and the corresponding slider 207 are engaged by a sliding connection, which in turn drives the transfer box 201, piston plate 205 and partition screen 206 to move to the right. When the lead screw 301 rotates in the reverse direction, the screw 301 and the corresponding slider 207 are engaged by a reverse threaded connection, and the guide rod 302 and the corresponding slider 207 are engaged by a sliding connection, which in turn drives the transfer box 201, piston plate 205 and partition screen 206 to move to the left.

[0044] Please see Figure 1 as well as Figure 3 In one embodiment, the piston-type adsorption assembly 20 further includes a lifting vertical rod 202, a horizontal rod 203, and a first elastic element 204. One end of the first elastic element 204 is connected to the piston plate 205, and the other end is connected to the inner wall of the transfer box 201, providing elastic support for the piston plate 205. One end of the lifting vertical rod 202 is fixedly connected to the piston plate 205, and the other end extends from the top of the transfer box 201 to above the transfer box 201 and is fixedly connected to the horizontal rod 203. The second driving assembly 50 includes a supporting inclined plate 501, a supporting vertical plate 502, and a fixed horizontal plate. 503 and the second elastic element 504, the fixed horizontal plate 503 is fixedly disposed inside the right side of the box body 10, one end of the supporting vertical plate 502 is hinged to the fixed horizontal plate 503, and the other end is hinged to the right end of the supporting inclined plate 501, the left end of the supporting inclined plate 501 extends to the left side of the box body 10 and is slidably connected to the inner wall of the box body 10, one end of the second elastic element 504 is connected to the inner wall of the box body 10, and the other end is connected to the supporting vertical plate 502, for providing elastic support to the supporting vertical plate 502 so that the supporting vertical plate 502 remains in a vertical state.

[0045] When the transfer box 201, piston plate 205, and partition net 206 move to the right, the transfer box 201 can drive the lifting vertical rod 202 and the horizontal rod 203 to move to the right simultaneously. When the horizontal rod 203 moves to the right, its end acts on the upper surface of the supporting inclined plate 501 and slides upward along the upper surface of the supporting inclined plate 501. At this time, the supporting vertical plate 502 remains vertical under the elastic support of the second elastic element 504, and the supporting inclined plate 501 remains inclined to provide stable support for the horizontal rod 203. When the horizontal rod 203 slides upward along the upper surface of the supporting inclined plate 501, it can drive the lifting vertical rod 202 to move upward relative to the transfer box 201. The lifting vertical rod 202 drives the piston. Plate 205 moves upward along the interior of transfer box 201, thereby drawing air from below frame 401 and filter screen 402. This causes the air to carry debris from the upper part of filter screen 402 into the transfer box 201, achieving debris adsorption. When the end of crossbar 203 slides away from the upper end of support inclined plate 501, transfer box 201 moves to the right to a position above guide plate 403. At this time, first elastic element 204 pushes piston plate 205, causing piston plate 205 to move downward along the interior of transfer box 201. Piston plate 205 drives lifting vertical bar 202 and crossbar 203 downward, while piston plate 205 forces air out of transfer box 201 to blow away debris from the bottom of mesh 206. This causes debris to fall onto the upper surface of the guide plate 403 and then be discharged through the discharge port 103. When the piston plate 205 moves down to its initial position inside the transfer box 201, the lead screw 301 rotates in the opposite direction, thereby causing the transfer box 201, piston plate 205, partition net 206, lifting vertical rod 202, and horizontal rod 203 to move to the left as a whole. When the horizontal rod 203 moves to the left, it acts on the vertical sidewall of the supporting vertical plate 502, thus pushing the supporting vertical plate 502 to rotate relative to the fixed horizontal plate 503. When the supporting vertical plate 502 rotates, it compresses the second elastic element 504 on one hand, and pushes the supporting inclined plate 501 to deflect on the other. As the support slope 501 is gradually leveled, the end of the crossbar 203 acts on the upper surface of the support slope 501 and slides to the left. At this time, the crossbar 203 can maintain a downward pressure on the support slope 501 under the support of the first elastic member 204, and the support slope 501 cannot bounce back to its original position until the end of the crossbar 203 is removed from the left end of the support slope 501. The second elastic member 504 pushes the support vertical plate 502 so that the support vertical plate 502 rotates in the opposite direction to the fixed crossbar 503 to a vertical position. The support vertical plate 502 pulls the support slope 501 so that the support slope 501 deflects in the opposite direction, so that the support slope 501 is tilted again.

[0046] Please see Figure 4 In one embodiment, the inner wall of the housing 10 is provided with a sliding groove 104, and the left end of the support inclined plate 501 is fixedly provided with a sliding pin 505, which extends into the sliding groove 104 and slides in cooperation with the sliding groove 104.

[0047] When the end of the crossbar 203 acts on the side wall of the support vertical plate 502, causing the support inclined plate 501 to deflect and lie flat, the left end of the support inclined plate 501 drives the sliding pin 505 to slide along the inside of the slide groove 104. When the end of the crossbar 203 is removed from the left end of the support inclined plate 501, the second elastic element 504 pushes the support vertical plate 503, causing the support inclined plate 501 to deflect in the opposite direction. At this time, the left end of the support inclined plate 501 drives the sliding pin 505 to slide in the opposite direction along the inside of the slide groove 104.

[0048] Please see Figure 1 In one embodiment, a drain outlet 102 is provided at the lower side wall of the box 10. Wastewater passing through the filter screen 402 from top to bottom falls to the bottom of the inner side of the box 10 and is then discharged through the drain outlet 102.

[0049] In one embodiment, the first elastic element 204 and the second elastic element 504 can be springs or metal sheets, and there is no limitation here.

[0050] In this embodiment of the invention, when it is necessary to recycle and reuse wastewater, the wastewater inlet 101 can be introduced into the tank 10. After the wastewater enters the tank 10, it passes through the water filtration assembly 40 from top to bottom. At this time, the impurities in the wastewater are intercepted at the upper part of the water filtration assembly 40, thereby achieving the separation of wastewater and impurities. In the above process, the first driving assembly 30 drives the adsorption piston assembly 20 to move back and forth along the upper part of the water filtration assembly 40. When the adsorption piston assembly 20 moves to the right along the upper part of the water filtration assembly 40, the second driving assembly 50 drives the adsorption piston assembly 20 to move upward, thereby targeting the impurities intercepted at the upper part of the water filtration assembly 40. Adsorption occurs, and the adsorption piston assembly 20 moves the adsorbed debris to the right. When the adsorption piston assembly 20 is removed from the upper area of ​​the water filter assembly 40, the second drive assembly 50 moves the adsorption piston assembly 20 downward, thereby releasing the adsorption of the debris and discharging the debris to the right side area of ​​the water filter assembly 40. This achieves automatic cleaning of the debris on the upper part of the water filter assembly 40. When the water filter assembly 40 is used to filter and remove impurities from water and sewage, this invention can achieve online adsorption cleaning of the water filter assembly 40. Compared with the existing scraping cleaning method, it has the advantages of better cleaning effect of the water filter assembly and no damage to the water filter assembly during the cleaning process.

[0051] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
