Description

Technical Field

[0001] The utility model relates to the field of microecological filter beds, and in particular to a water inlet filtering structure of a microecological filter bed. Background Art

[0002] The microecological filter bed technology is a world-leading microecological filter bed technology that was introduced and designed based on the German water system ecological restoration theory. This technology is widely used in sewage treatment and reclaimed water reuse, landscape water ecological management and restoration, comprehensive rainwater utilization and green building evaluation, and deep treatment of tailwater from urban sewage treatment plants. It focuses on creating an ecological water management concept with sustainable design and low-carbon ecological operation, and creates a first-class technology and service system in the field of energy conservation in building water environment.

[0003] In the prior art, there is a microecological filter bed with application number CN202022456861.4. In the above scheme, by “the filtering accuracy of the first filter screen and the second filter screen in the sedimentation tank is different and the filtering accuracy of the second filter screen is higher than that of the first filter screen, not only can the step-by-step filtration of sewage be achieved, but also the probability of sewage blocking the filter screen is effectively reduced; the sewage after primary filtration is sprayed on the surface of the microecological filter bed through the outlet in the extension pipe, so that the sewage passes through the planting matrix layer and enters the filter stone layer more evenly”. However, the above scheme has a poor effect on sewage filtration. At the same time, when the sewage is discharged into the sedimentation tank, it is easy to cause the water inside the sedimentation tank to become turbid, which is easy to cause the filter screen to be blocked. The filter screen needs to be frequently cleaned and replaced, which increases the labor intensity. At the same time, the efficiency of using a single sedimentation tank is low, which delays the efficiency of sedimentation. How to invent a microecological filter bed water inlet filtration structure to improve these problems has become a problem that needs to be solved urgently by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a microecological filter bed water inlet filtration structure, which aims to improve the poor sewage filtration effect in the above scheme, and the problem that when sewage is discharged into the sedimentation tank, the water inside the sedimentation tank is easily turbid, which increases the probability of filter clogging and requires frequent cleaning and replacement of the filter.

[0005] The utility model is implemented as follows: a microecological filter bed water inlet filtration structure, comprising

[0006] A water delivery mechanism, the water delivery mechanism comprising a first delivery assembly;

[0007] The filtering mechanism comprises a filtering assembly and a second conveying assembly, the filtering assembly comprises a sedimentation tank, a partition is provided in the middle of the sedimentation tank, the partition divides the sedimentation tank into two filter tanks of the same size, the first conveying assembly is respectively installed on both sides of one end of the sedimentation tank, the second conveying assembly comprises a floating plate, the top of the floating plate is connected to a conveying pipe, and the floating plates are respectively installed on both sides of the other end of the sedimentation tank with limited sliding.

[0008] In a preferred technical solution of the present utility model, the filter assembly also includes a first partition and a second partition, the first partition is respectively fixedly installed in the middle of both sides of the sedimentation tank, the second partition is respectively fixedly installed on the side of the first partition away from the first conveying assembly, the second partition is located in the middle of the first partition and the inner wall of the sedimentation tank, the top of the first partition and the second partition are respectively fixedly installed with upper filter screens, and the top of the sedimentation tank and the upper filter screen are sealed with a cover plate.

[0009] In a preferred technical solution of the present utility model, support frames are fixedly installed between the first partition and the second partition and between the first partition and the inner wall of the sedimentation tank, respectively. The support frames are fixedly installed on both sides of the interior of the sedimentation tank. A first horizontal filter plate and a second horizontal filter plate are respectively arranged above the support frames. The first horizontal filter plate is located between the first partition and the inner wall of the sedimentation tank, and the second horizontal filter plate is located between the first partition and the second partition.

[0010] In a preferred technical solution of the present invention, a baffle is fixedly connected to one side of the top of the first horizontal filter plate and the second horizontal filter plate, the baffle above the first horizontal filter plate is arranged on the side away from the first partition plate, and the baffle at the top of the second horizontal filter plate is arranged on the side away from the second partition plate.

[0011] In a preferred technical solution of the present invention, one end of the second horizontal filter plate close to the first partition plate is not in contact with the first partition plate.

[0012] In a preferred technical solution of the present utility model, the first conveying component includes an input pipe, one end of the input pipe is connected to an external water source, the other end of the input pipe is connected to a connecting pipe, the other end of the connecting pipe is connected to an output pipe, and the input pipe, connecting pipe and output pipe are respectively arranged between the inner wall of the sedimentation tank and the first partition.

[0016] In a preferred technical solution of the utility model, a water guide plate is fixedly provided on the top of the floating plate, and the water guide plate is arranged in an arc shape.

[0017] The beneficial effect of the utility model is that the utility model obtains a microecological filter bed water inlet filter structure through the above design. When in use, the input pipe discharges sewage into the two sides of the sedimentation tank, and cooperates with the first partition to isolate and precipitate the sewage. When the sewage continues to increase and overflows the first horizontal filter plate, it is filtered through the first horizontal filter plate. The filtered water is filtered again through the upper filter screen above the first partition, and the filtered water flows into between the first partition and the second partition. When the water overflows the second horizontal filter plate, the second horizontal filter plate will filter the sewage, so that the filtered water flows into between the second partition and the sedimentation tank.

When water is used, the water below is extracted through the delivery pipe. The water is filtered many times and there are very few impurities in the water. If one side of the sedimentation tank is cleaned or repaired, the other side is used, which improves the efficiency of use, facilitates multiple filtration of sewage, improves the filtering effect, reduces the work intensity and effectively avoids frequent cleaning and replacement of filter plates and filter screens.

[0027] The water delivery mechanism 100 includes a first delivery assembly 110;

[0028] The filtering mechanism 200 includes a filtering assembly 210 and a second conveying assembly 220. The filtering assembly 210 includes a sedimentation tank 211. A partition is provided in the middle of the sedimentation tank 211. The partition divides the sedimentation tank 211 into two filter tanks of the same size. The first conveying assembly 110 is respectively installed on both sides of one end of the sedimentation tank 211. The second conveying assembly 220 includes a floating plate 221. The top of the floating plate 221 is connected to a conveying pipe 224. The floating plates 221 are respectively slidably installed on both sides of the other end of the sedimentation tank 211. The floating plate 221 is used to cooperate with the conveying pipe 224 to extract water from the upper layer inside the sedimentation tank 211 to prevent turbid water from being extracted from the bottom. The conveying pipe 224 is a corrugated hose that is convenient for cooperating with the floating plate 221 to be stretched up and down.

[0029] See also Figure 3 and Figure 4The filter assembly 210 also includes a first partition 212 and a second partition 213. The first partition 212 is fixedly installed in the middle of both sides of the sedimentation tank 211, and the second partition 213 is fixedly installed on the side of the first partition 212 away from the first conveying assembly 110. The second partition 213 is located in the middle of the first partition 212 and the inner wall of the sedimentation tank 211. The tops of the first partition 212 and the second partition 213 are respectively fixedly installed with upper filter screens 215. The tops of the sedimentation tank 211 and the upper filter screens 215 are sealed with a cover plate 219. The aperture of the upper filter screen 215 on the first partition 212 is larger than that of the upper filter screen 215 above the second partition 213. Filtration in batches increases the service life of the filter screens.

[0030] Support frames 214 are fixedly installed between the first partition 212 and the second partition 213 and between the first partition 212 and the inner wall of the sedimentation tank 211. The support frames 214 are fixedly installed on both sides of the interior of the sedimentation tank 211. The first horizontal filter plate 216 and the second horizontal filter plate 217 are respectively arranged above the support frames 214. The first horizontal filter plate 216 is located between the first partition 212 and the inner wall of the sedimentation tank 211, and the second horizontal filter plate 217 is located between the first partition 212 and the second partition 213. A stop bar 218 is fixedly connected to one side of the top of the first horizontal filter plate 216 and the second horizontal filter plate 217. The stop bar 218 above the first horizontal filter plate 216 is arranged on the side away from the first partition 212, and the stop bar 218 at the top of the second horizontal filter plate 217 is arranged on the side away from the second partition 213. The stop bar 218 is used to prevent water from overflowing the first horizontal filter plate 216 and the second horizontal filter plate 217. One end of the second horizontal filter plate 217 close to the first partition 212 is not attached to the first partition 212, the aperture of the first horizontal filter plate 216 is larger than the aperture of the upper filter screen 215 above the first partition 212, and the aperture of the second horizontal filter plate 217 is smaller than the aperture of the upper filter screen 215 above the second partition 213, which is larger than the aperture of the upper filter screen 215 above the first partition 212, thereby improving the filtering effect and reducing the number of times the filter screen is replaced and cleaned. At the same time, the height of the second partition 213 is lower than the height of the first partition 212, preventing water from flowing back to the top of the first partition 212 when water flows above the second partition 213.

[0031] See also Figures 3 to 5The first conveying assembly 110 includes an input pipe 111, one end of which is connected to an external water source, the other end of which is connected to a connecting pipe 112, and the other end of which is connected to an output pipe 113. The input pipe 111, the connecting pipe 112 and the output pipe 113 are respectively arranged between the inner wall of the sedimentation tank 211 and the first partition 212. The output pipe 113 is arranged in a tobacco bag shape, and the water outlet of the output pipe 113 discharges water upward. The second conveying assembly 220 also includes a support block 222, and the four corners of the bottom of the floating plate 221 are respectively fixedly connected with the support blocks 222, and the conveying pipe 224 passes through the floating plate 221. A plurality of through holes are evenly spaced on both sides of the floating plate 221, and the support block 222 is used to prevent the floating plate 221 from sticking to the bottom of the sedimentation tank 211 and prevent the conveying pipe 224 from pumping the sediment at the bottom of the sedimentation tank 211. A water guide plate 223 is fixedly provided on the top of the floating plate 221. The water guide plate 223 is arranged in an arc shape. The water guide plate 223 is used to guide the water on both sides so that the water is located at the bottom of the floating plate 221. The delivery pipe 224 pumps the water below through a water pump.

[0032] Working principle: the input pipe 111 discharges the sewage into the inside of both sides of the sedimentation tank 211, and cooperates with the first partition 212 to isolate and precipitate the sewage. When the sewage continues to increase and overflows the first horizontal filter plate 216, it is filtered by the first horizontal filter plate 216, and the filtered water is filtered again by the upper filter screen 215 above the first partition 212. The filtered water flows into between the first partition 212 and the second partition 213. When the water overflows the second horizontal filter plate 217, the second horizontal filter plate 217 will filter the sewage, so that the filtered water flows into between the second partition 213 and the sedimentation tank 211. The water slowly rises to lift up the floating plate 221. When the water falls again, it will pass through the through holes on both sides of the floating plate 221 to continuously lift up the floating plate 221. When using water, the water below is extracted through the delivery pipe 224. The water has been filtered many times and there are very few impurities in the water. If one side of the sedimentation tank 211 is cleaned or repaired, the other side is used.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
