Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a domestic sewage filtering system. Background Art

[0002] Domestic sewage refers to wastewater generated by human daily life, washing, hand washing, kitchen discharge and toilet flushing. It contains various organic matter, suspended matter, grease, microorganisms and chemicals, etc. It usually contains high concentrations of ammonia nitrogen, organic carbon and planktonic microorganisms. The treatment of domestic sewage is very important to reduce pollution to the environment and protect water resources.

[0003] In the first process of domestic sewage treatment, screens are used to preliminarily filter larger impurities in the sewage to prevent them from entering the subsequent treatment process and avoid damage and blockage to the treatment equipment. However, as time goes by, these impurities will gradually accumulate on the screens, causing blockage and affecting their normal filtering function. Therefore, the screens need to be cleaned regularly. However, when cleaning the screens, the water inlet valve needs to be closed to suspend the sewage treatment process, and the cleaning mainly relies on manual labor, which is more troublesome. Utility Model Content

[0004] The utility model aims to provide a domestic sewage filtering system which can avoid grid plate blockage and is easy to clean.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] Domestic sewage filtration system, including tank body.

[0007] One side of the pool body is connected to a water inlet pipe, and the other side of the pool body is connected to a drain pipe. A partition is installed inside the pool body, and a circular grille plate is rotatably installed inside the partition. A fixing ring is installed on the side of the circular grille plate away from the water inlet pipe through a driving mechanism. The driving mechanism can drive the circular grille plate to rotate, and a cleaning brush is vertically arranged on the side of the circular grille plate facing the water inlet pipe.

[0008] A sloped base is installed near the bottom of the partition surface facing the water inlet pipe, and a collection box is arranged inside the pool body on the side of the sloped base. Leakage holes are evenly opened at the bottom of the collection box, and pulling ropes are connected to both sides of the upper surface of the collection box.

[0009] It can be seen that the circular grille plate is driven to rotate by the driving mechanism, so that the surface of the circular grille plate rubs against the cleaning brush, so that the impurities attached to the surface of the circular grille plate can be removed to prevent the impurities from affecting the filtering performance of the circular grille plate, and the removed impurities fall down on the surface of the inclined base and slide down along the inclined surface of the inclined base into the collection box, so that the impurities generated after cleaning can be collected. Workers only need to take out the collection box regularly for cleaning. Therefore, there is no need to suspend the sewage treatment process when cleaning the circular grille plate, which ensures the normal operation of the sewage treatment system, reduces manual labor, and reduces maintenance costs. The rotation of the circular grille plate also has the function of cutting viscous liquids, effectively improving the filtration efficiency and avoiding clogging.

[0010] Furthermore, the driving mechanism includes a mounting seat installed on the surface of the partition facing the water inlet pipe, a first motor is installed on the mounting seat, the end of the output shaft of the first motor is connected to a connecting shaft, and the end of the connecting shaft passes through the other side of the partition, a gear is installed on the end of the connecting shaft, a gear ring is installed on the outer surface of the fixing ring, and the gear is meshingly connected with the gear ring.

[0011] By starting the first motor, the connecting shaft can be driven to rotate, and then the gear can be driven to rotate. Through the meshing action between the gear and the gear ring, the purpose of driving the fixed ring and the circular grille plate to rotate is achieved. When the circular grille plate rotates, the part in contact with the cleaning brush rubs, thereby cleaning impurities.

[0012] Furthermore, a shell is installed on the outer surface of the partition, and the rod body of the cleaning brush passes through the interior of the shell, the outer surface of the cleaning brush rod body is provided with a shoulder, the outer surface of the cleaning brush rod body is sleeved with a spring, and the two ends of the spring are respectively abutted against the shoulder and the inner wall of the shell, an extrusion block is installed on the top of the cleaning brush rod body, and a cam is sleeved on the outer surface of the connecting shaft, and the cam is extruded and matched with the extrusion block.

[0013] When the first motor is started to drive the circular grille plate to rotate, the connecting shaft drives the cam to rotate, and the cam continuously squeezes the extrusion block downward, so that the extrusion block drives the cleaning brush to move downward and compresses the spring. When the extrusion applied by the cam to the extrusion block disappears, the spring releases the elastic force to drive the cleaning brush to move up quickly. Therefore, the continuous rotation of the connecting shaft can drive the cleaning brush to move up and down reciprocatingly, and the rotation of the circular grille plate can further improve the cleaning effect of the circular grille plate. Moreover, the two actions only require one driving source, the structure is reasonable, and it kills two birds with one stone.

[0014] Furthermore, vertical plates are installed on both sides of the upper surface of the pool body, a rotating shaft is rotatably connected between the two vertical plates, and the upper end of the pulling rope is wrapped around the outer surface of the rotating shaft, a second motor is installed on the outer surface of one of the vertical plates, and the end of the second motor output shaft is connected to the rotating shaft.

[0015] By starting the second motor to drive the rotating shaft to rotate, the rotating shaft can reel in the pulling rope, so that the collecting box can be lifted upward and dropped off the water surface, thereby facilitating the cleaning of the impurities collected in the collecting box.

[0016] Furthermore, both inner walls of the pool body are provided with slide grooves along the height direction thereof, a sliding block is provided inside the slide groove, and the end of the sliding block is connected to the collection box.

[0017] By setting the slide groove and the slider, the collecting box can be limited when it is lifted or lowered, so that it will not deviate or tilt.

[0018] Furthermore, the height of the first motor is higher than the height of the pool body.

[0019] The height of the first motor is higher than the water surface to avoid water ingress and damage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4As shown, the domestic sewage filtration system includes a tank body 100, one side of the tank body 100 is connected to a water inlet pipe 101, the other side of the tank body 100 is connected to a drain pipe 102, a partition 103 is installed inside the tank body 100, a circular grille plate 104 is rotatably installed inside the partition 103, a side of the circular grille plate 104 away from the water inlet pipe 101 is installed with a fixing ring 105 through a driving mechanism 200, the driving mechanism 200 can drive the circular grille plate 104 to rotate, and a cleaning brush 106 is vertically arranged on the side of the circular grille plate 104 facing the water inlet pipe 101; an inclined base 107 is installed near the bottom of the partition 103 facing the water inlet pipe 101, and a collecting box 108 is arranged on the side of the inclined base 107 inside the tank body 100, and leakage holes 109 are evenly opened at the bottom of the collecting box 108, and both sides of the upper surface of the collecting box 108 are connected to pulling ropes 110.

[0027] When sewage enters the tank body 100 from the water inlet pipe 101, it is filtered through the circular grille plate 104 and then discharged into the next process from the drain pipe 102. After the circular grille plate 104 filters the impurities in the domestic sewage, the impurities adhere to its surface. The circular grille plate 104 can be driven to rotate by the driving mechanism 200. When the circular grille plate 104 rotates, it produces relative friction with the cleaning brush 106, so that the cleaning brush 106 can remove the impurities attached to the surface of the circular grille plate 104, thereby ensuring the normal filtering performance of the circular grille plate 104, so that the sewage can flow normally and avoid blockage. The removed impurities fall downward on the inclined base 107 under the action of gravity, and flow along the inclined surface of the inclined base 107 to the collection box 108. When the impurities collected in the collection box 108 reach a certain amount, the collection box 108 can be lifted from the sewage by using the pulling rope 110, and the leakage hole 109 can drain the sewage, so that only the impurities are in the collection box 108, and then the collection box 108 can be cleaned.

[0028] Specifically, the driving mechanism 200 includes a mounting base 201 installed on the surface of the partition 103 facing the water inlet pipe 101, and a first motor 202 is installed on the mounting base 201. The end of the output shaft of the first motor 202 is connected to the connecting shaft 203, and the end of the connecting shaft 203 passes through the other side of the partition 103. A gear 204 is installed at the end of the connecting shaft 203, and a gear ring 205 is installed on the outer surface of the fixing ring 105, and the gear 204 is meshingly connected with the gear ring 205. By starting the first motor 202, the connecting shaft 203 can be driven to rotate, and then the gear 204 can be driven to rotate. Through the meshing action between the gear 204 and the gear ring 205, the purpose of driving the fixing ring 105 and the circular grille plate 104 to rotate is achieved. When the circular grille plate 104 rotates, the part in contact with the cleaning brush 106 rubs, thereby cleaning impurities.

[0029] Specifically, a shell 300 is installed on the outer surface of the partition 103, and the rod body of the cleaning brush 106 passes through the interior of the shell 300. A shoulder 301 is provided on the outer surface of the rod body of the cleaning brush 106. A spring 302 is sleeved on the outer surface of the rod body of the cleaning brush 106, and the two ends of the spring 302 are respectively abutted against the shoulder 301 and the inner wall of the shell 300. An extrusion block 304 is installed on the top of the rod body of the cleaning brush 106. A cam 303 is sleeved on the outer surface of the connecting shaft 203. The cam 303 is extruded and matched with the extrusion block 304. When the first motor 202 is started to drive the circular grille plate 104 to rotate, the connecting shaft 203 The connecting shaft 203 drives the cam 303 to rotate, and the cam 303 continuously squeezes the squeezing block 304 downward, so that the squeezing block 304 drives the cleaning brush 106 to move downward and compress the spring 302. When the squeezing force applied by the cam 303 to the squeezing block 304 disappears, the spring 302 releases the elastic force to drive the cleaning brush 106 to move up quickly. Therefore, the continuous rotation of the connecting shaft 203 can drive the cleaning brush 106 to move up and down reciprocatingly, and cooperate with the rotation of the circular grille plate 104 to further improve the cleaning effect of the circular grille plate 104. Moreover, the two actions only require one driving source, the structure is reasonable, and two birds with one stone are achieved.

[0030] Specifically, vertical plates 400 are installed on both sides of the upper surface of the pool body 100, and a rotating shaft 401 is rotatably connected between the two vertical plates 400, and the upper end of the pulling rope 110 is wrapped around the outer surface of the rotating shaft 401. A second motor 402 is installed on the outer surface of one of the vertical plates 400, and the end of the output shaft of the second motor 402 is connected to the rotating shaft 401. By starting the second motor 402 to drive the rotating shaft 401 to rotate, the rotating shaft 401 can be used to reel in the pulling rope 110, so that the collecting box 108 can be lifted upward and fall off the water surface, thereby facilitating the cleaning of the impurities collected in the collecting box 108.

[0031] Specifically, the inner walls on both sides of the pool body 100 are provided with slide grooves along the height direction, and a slider is provided inside the slide groove, and the end of the slider is connected to the collection box 108. Through the setting of the slide groove and the slider, the collection box 108 can be limited when it is raised or lowered, so that it will not be offset or tilted.
