Description

Technical Field

[0001] This utility model relates to the field of rural sewage treatment technology, specifically to a sedimentation and filtration device for treating rural domestic sewage. Background Technology

[0002] Rural domestic sewage refers to wastewater generated by rural residents in their daily lives, including wastewater discharged from washing, bathing, kitchens, and toilets. Its discharge characteristics include low per capita discharge, large daily discharge variation coefficient, obvious seasonal changes in water quantity and quality, relatively stable pollutants, and great difficulty in collection.

[0003] Although individual discharges of rural domestic sewage are low, the combined discharges from multiple residents create a large volume of wastewater that needs treatment. This wastewater continuously enters the treatment tank, and coagulants continuously process it. However, the increased discharge volume reduces treatment efficiency, resulting in poor wastewater treatment outcomes.

[0004] According to Chinese Patent Publication No. CN220766770U, "A Sedimentation and Filtration Device for Rural Domestic Sewage Treatment," the device mainly describes a process where sewage enters a filter box and passes through three layers of filters: a first filter plate, a second filter plate, and a third filter plate. Solid impurities are deposited on the filter plates. The filtered liquid then enters a sedimentation tank via a first water supply pipe. After adding flocculant and allowing it to flocculate for a period of time, the flocculated products settle at the bottom of the sedimentation tank. At this point, a drive motor drives a lead screw to rotate, causing a moving plate to move a connecting shaft along the lead screw. The connecting shaft then drives a first extrusion plate to extrude water from the solid impurities on the filter plates. The hydraulic telescopic rod extends, causing a second extrusion plate to extrude water from the flocculated products. This process removes solid impurities and sewage carried by the flocculated products, enhancing the overall treatment of sewage. During wastewater treatment, increased flow rates reduce sedimentation time, necessitating continuous water circulation and increasing the treatment time and efficiency of the treatment tank.

[0005] Therefore, a sedimentation and filtration device for rural domestic sewage treatment is proposed to address the problem that, during the wastewater treatment process, an increase in wastewater flow leads to a decrease in sewage sedimentation time, requiring continuous water circulation and increasing the treatment time and efficiency of the treatment tank. Utility Model Content

[0006] The technical problem this invention aims to solve is that, in the process of wastewater treatment, an increase in wastewater flow rate leads to a decrease in sewage sedimentation time, requiring continuous water circulation and increasing the treatment time and efficiency of the treatment tank. Therefore, a sedimentation and filtration device for rural domestic sewage treatment is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a sedimentation and filtration device for rural domestic sewage treatment, including a treatment box, a filter screen fixedly connected inside the treatment box, a groove opened on one side of the treatment box with an adjusting plate fixedly connected inside the groove, a water level sensor fixedly connected to the upper side of the treatment box, a partition fixedly connected to the bottom side of the treatment box with the water level sensor, a water inlet groove opened on one side of the partition, a first motor fixedly connected to one side of the treatment box, a screw fixedly connected to the output end of the first motor, a sealing plate threaded onto the screw, the sealing plate contacting the partition, a sedimentation chamber set on the bottom side of the partition in the treatment box, a water guide pipe fixedly connected to one side of the treatment box with the sedimentation chamber, an electric push rod fixedly connected inside the treatment box, a pressure plate fixedly connected to the output end of the electric push rod, and the pressure plate contacting the filter screen.

[0010] As a preferred technical solution of this utility model, a water guide channel is provided on one side of the treatment box, and a temporary water tank is fixedly connected to the treatment box on one side of the water guide channel. A second motor is fixedly connected to the treatment box on one side of the temporary water tank, and a cover plate is fixedly connected to the output end of the second motor. By driving the cover plate to rotate through the second motor, the temporary water tank can have the effect of water storage and waterproofing, and increase the sedimentation time of wastewater.

[0011] As a preferred technical solution of this utility model, a folding cover is fixedly connected inside the treatment box. The folding cover is in contact with the sealing plate and is sleeved on the outside of the screw. By setting the folding cover, small particulate impurities in the wastewater can be prevented from contacting the screw and causing damage.

[0012] This utility model has the following advantages: by setting a partition in the treatment tank and a movable sealing plate, a partition can be formed, so that the upper side of the treatment tank can temporarily store water. Then, with the help of a water level sensor for monitoring, excess water is stored in a temporary water tank, which facilitates wastewater sedimentation and improves the water treatment effect.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The sedimentation and filtration device for rural domestic sewage treatment shown includes a treatment tank 1, a filter screen 2 fixedly connected inside the treatment tank 1, a groove on one side of the treatment tank 1 located from the filter screen 2, and an adjusting plate 3 fixedly connected inside the groove. A water level sensor 4 is fixedly connected to the upper side of the treatment tank 1. The sensor converts the water level parameter at the measured point into a corresponding electrical signal in real time, which causes a second motor to drive a cover plate 19 to rotate, thereby promoting the discharge of water from a temporary water tank 18. A partition plate 5 is fixedly connected to the bottom side of the treatment tank 1 from the water level sensor 4. A water inlet trough 6 is opened on one side of the partition plate 5. A first motor is fixedly connected to one side of the treatment tank 1. The output end of the first motor... A screw 7 is fixedly connected, and a sealing plate 8 is threaded onto the screw 7. A first motor drives the screw 7 to rotate, which enables the sealing plate 8 to move, thereby allowing the upper side of the treatment box 1 to be separated from the sedimentation chamber 9. The sealing plate 8 contacts the partition 5. The sedimentation chamber 9 is located on the bottom side of the partition 5 in the treatment box 1. A water guide pipe 10 is fixedly connected to one side of the sedimentation chamber 9 in the treatment box 1. An electric push rod 15 is fixedly connected inside the treatment box 1. A pressure plate 16 is fixedly connected to the output end of the electric push rod 15. The pressure plate 16 contacts the filter screen 2. When the electric push rod 15 extends, the pressure plate 16 can squeeze the large particles of impurities at the lowest point of the filter screen 2, thereby facilitating dewatering.

[0019] The nozzles are uniformly and fixedly connected to the upper end of the gas collection pipe 12, the gas collection pipe 12 is fixedly connected to the output end of the air pump 11, and the air pump 11 is fixedly connected to one side of the treatment box 1. By setting the gas collection pipe 12 and the nozzles, the contact between oxygen and wastewater can be improved.

[0020] The guide fan 14 is rotatably connected to the dustproof net 13, which is fixedly connected to the ventilation slot. The ventilation slot is located at the upper end of the treatment box 1. By setting the dustproof net 13 and the guide fan 14, it is easy to guide the airflow into the treatment box 1, thereby promoting the contact between oxygen and water.

[0021] The cover plate 19 is fixedly connected to the output end of the second motor. The second motor is fixedly connected to one side of the treatment box 1 and close to the temporary water tank 18. The temporary water tank 18 is fixedly connected to one side of the treatment box 1. The water guide channel 17 is lower than the height monitored by the water level sensor 4. By setting the second motor to drive the cover plate 19 to rotate, the bottom side of the temporary water tank 18 can be made to be in the open state.

[0022] The screw 7 is fitted with a folding cover 20 on its outer side. The sealing plate 8 is in contact with the folding cover 20. The folding cover 20 is fixedly connected inside the processing box 1. The folding cover 20 blocks small particles of impurities from contacting the screw 7, thereby preventing poor rotation of the screw 7.

[0023] Working principle: Water enters the treatment tank 1 and is filtered by the filter screen 2. The treated water falls onto the baffle plate 5, where impurities are squeezed by the pressure plate 16, causing the water to separate. Water that is higher than the guide channel 17 enters the temporary water tank 18. At this time, the air pump 11, in conjunction with the guide fan 14, introduces air to contact the water, providing aeration. The water level in the treatment tank 1 is monitored by the water level sensor 4. When the water level is higher than the water level point of the water level sensor 4, the water level sensor 4 transmits an electrical signal to the first motor, which promotes the rotation of the screw 7, thereby moving the sealing plate 8. The inlet channel 6 is in the open state, and the water enters the sedimentation chamber 9 for sedimentation. This process can improve the treatment effect of rural domestic sewage and facilitate wastewater sedimentation.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
