Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a sewage treatment device for rural areas. Background Art

[0002] Rural sewage treatment refers to the process of collecting, treating and discharging domestic sewage, agricultural production sewage and rural industrial sewage of rural residents, etc., which can reduce the pollution of sewage to soil, water bodies and ecosystems and protect the rural ecological environment. In some existing sewage treatment devices during operation, impurities in sewage are filtered and cleaned through a filter plate thereon, which is prone to clogging of the filter holes on the filter plate. Generally, the filter plate is installed in a box and is not easy to disassemble and clean. At the same time, when the filter plate is filled with impurities, the impurities are inside the filter plate and are not easy to take out from the outside, and the whole process is time-consuming and laborious. Summary of the Invention

[0003] The purpose of the present invention is to provide a sewage treatment device for rural areas to overcome the above-mentioned defects in the prior art.

[0004] A sewage treatment device for rural areas includes a static water tank, a filter tank and a cleaning mechanism. An inlet pipe is provided on a bracket in the static water tank. The filter tank is communicated with the static water tank through a connecting pipe. The filter tank is connected to the water inlet of a water suction pump through an outlet pipe;

[0005] The cleaning mechanism is arranged in a filter plate on the inner wall of the filter tank and is used to prevent the filter holes on the filter plate from being blocked and discharge the remaining impurities from the filter tank.

[0006] Preferably, the filter plate is of a "U"-shaped structure and faces the connecting pipe.

[0007] Preferably, a quartz sand filter plate and an activated carbon filter plate are sequentially arranged in the filter tank.

[0008] Preferably, the cleaning mechanism includes a discharge hopper, a guide rod, a push plate, a spring and a cleaning brush. The discharge hopper is arranged at the top of the filter tank and above the filter plate. The top of the discharge hopper is detachably connected with a cover plate through an industrial buckle. The lower end of the guide rod is arranged on a fixed plate on the inner wall of the filter tank, and the upper end of the guide rod is connected to a stop block at the bottom of the discharge hopper. The push plate is arranged in the filter plate and is slidably connected to the guide rod. A stop frame for limiting the push plate is arranged at the bottom of the filter plate. The spring is sleeved on the guide rod and is located between the push plate and the fixed plate. A rotating shaft is rotatably connected to the middle of the push plate. A cleaning brush and an impeller are arranged on the rotating shaft, and the impeller faces the connecting pipe. A ball is rollingly connected to the top of the rotating shaft.

[0009] Preferably, a valve is installed on the inlet pipe.

[0010] Preferably, the filter box is arranged on a ladder frame.

[0011] The beneficial effects achieved by the present invention are:

[0012] 1. The filter plate in the filter box filters the larger impurities in the sewage. At the same time, the flowing sewage drives the impeller to rotate, so that the cleaning brush on the rotating shaft brushes the filter holes on the filter plate to avoid clogging of the filter holes on the filter plate. Then, the quartz sand filter plate and activated carbon filter plate in the filter box absorb and filter the impurities in the sewage.

[0013] 2. When the filter plate is full of impurities, open the cover plate and the push plate will move upward along the guide rod under the action of the spring force, so that the impurities on the filter plate are pushed out of the filter plate and enter the feed hopper, which is convenient for workers to clean out the impurities. The cleaning brush moves up to continue brushing and cleaning the filter plate;

[0014] 3. After the impurities are taken out from the discharge hopper, the ball on the rotating shaft is pressed downward by the cover plate, and the rotating shaft drives the push plate to move downward, and the cleaning brush brushes the filter plate again;

[0015] The present application drives the impeller through the flow of sewage to rotate the cleaning brush to clean the filter plate during operation. At the same time, the cleaning brush moves up to clean the filter plate when impurities are removed. In addition, when the push plate is reset, the cleaning brush moves down to clean the filter plate. Through multiple cleanings of the cleaning brush, clogging of the filter plate pores can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0024] The following is a further detailed description of the specific implementation mode of the present invention by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.

[0025] As Figure 1-3 shown, the present invention provides a sewage treatment device for rural use, including a static water tank 1, a filter tank 3 and a cleaning mechanism 6. An inlet water pipe 2 with a valve 21 installed is provided on the bracket 11 in the static water tank 1. The filter tank 3 is communicated with the static water tank 1 through a connecting pipe 4. The filter tank 3 is arranged on the ladder rack 7 to facilitate workers to carry out maintenance and clean impurities.

[0026] In addition, a quartz sand filter plate 31 and an activated carbon filter plate 32 are sequentially arranged in the filter tank 3 to perform multiple adsorption on sewage and improve the sewage treatment effect. The filter tank 3 is connected to the water inlet of the water suction pump through a water outlet pipe 5. The cleaning mechanism 6 is arranged in the filter plate 61 on the inner wall of the filter tank 3 and is used to prevent the filter holes on the filter plate 61 from being blocked and discharge the residual impurities from the filter tank 3.

[0027] As Figure 4-7 shown, the cleaning mechanism 6 includes a discharge hopper 62, a guide rod 63, a push plate 64, a spring 65 and a cleaning brush 67. The filter plate 61 is of a "U" - shaped structure and faces the connecting pipe 4. The discharge hopper 62 is arranged at the top of the filter tank 3 and above the filter plate 61. The top of the discharge hopper 62 is detachably connected with a cover plate 622 through an industrial buckle 621. The lower end of the guide rod 63 is arranged on the fixing plate 631 on the inner wall of the filter tank 3, and the upper end of the guide rod 63 is connected with a stop block 632 at the bottom of the discharge hopper 62. The push plate 64 is arranged in the filter plate 61 and is slidably connected to the guide rod 63. A retaining frame 611 for limiting the push plate 64 is arranged at the bottom of the filter plate 61. The spring 65 is sleeved on the guide rod 63 and is located between the push plate 64 and the fixing plate 631. A rotating shaft 66 is rotatably connected to the middle of the push plate 64. A cleaning brush 67 and an impeller 68 are arranged on the rotating shaft 66, and the impeller 68 is aligned with the connecting pipe 4. A ball 661 is rollingly connected to the top of the rotating shaft 66.

[0028] Working principle:

[0029] During operation, the valve 21 on the water inlet pipe 2 is opened, and the sewage treated in the previous process is passed into the static water tank 1 through the water inlet pipe 2, and the water suction pump connected to the water outlet pipe 5 is turned on, and the sewage enters the filter box 3 from the connecting pipe 4, and the larger impurities in the sewage are filtered through the filter plate 61, and the sewage impacts the impeller 68 on the rotating shaft 66, so that the rotating shaft 66 rotates, and the cleaning brush 67 on the rotating shaft 66 cleans the filter holes on the filter plate 61 to prevent the filter holes on the filter plate 61 from being blocked, and then the impurities in the sewage are adsorbed and filtered through the quartz sand filter material plate 31 and the activated carbon filter material plate 32 in the filter box 3, and finally flows into the next process through the water outlet pipe 5 on the filter box 3 for treatment;

[0030] When the filter plate 61 is filled with impurities, the industrial buckle 621 on the discharge hopper 62 is opened, and the cover plate 622 is removed from the discharge hopper 62. Then, under the elastic force of the spring 65, the push plate 64 is driven to move upward along the guide rod 63, so that the impurities on the filter plate 61 are pushed out of the filter plate 61 and enter the feed hopper. At the same time, the cleaning brush 67 and the rotating shaft 66 move upward. During the upward movement of the cleaning brush 67, the filter plate 61 is continuously brushed and cleaned, and then the impurities are removed from the discharge hopper 62.

[0031] After the impurities are taken out from the discharge hopper 62, the ball 661 on the rotating shaft 66 is pressed downward by the cover plate 622, and the rotating shaft 66 drives the push plate 64 to move downward. The spring 65 on the guide rod 63 is compressed, so that the push plate 64 contacts the baffle frame 611 at the bottom of the filter plate 61, and the cleaning brush 67 brushes the filter plate 61 again to clean it. Finally, the discharge hopper 62 is connected to the cover plate 622 through the industrial buckle 621.

[0032] In summary, the present application drives the impeller 68 through the flow of sewage to rotate the cleaning brush 67 to clean the filter plate 61 during operation. At the same time, the cleaning brush 67 moves up to clean the filter plate 61 when impurities are removed. In addition, when the push plate 64 is reset, the cleaning brush 67 moves down to clean the filter plate 61. Through multiple cleanings of the cleaning brush 67, blockage of the filter holes of the filter plate 61 can be avoided.

[0033] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
