Description

Technical Field

[0001] The present application relates to the field of sewage treatment, and in particular, to a separation and filtration device for sewage treatment. Background Art

[0002] Among the water pollution caused by human production activities, water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and has complex components. It is not only difficult to purify in water, but also difficult to treat. The pollutants contained in industrial wastewater vary greatly depending on the type of factory. Even for the same type of factory, the quality and quantity of pollutants contained are different due to different production processes. In addition to the direct injection of industrial wastewater into water bodies to cause pollution, solid waste and waste gas can also pollute water bodies. Agricultural pollution is first caused by the loosening of the land surface due to farming or land reclamation. When it rains when the soil and terrain are not yet stable, a large amount of sediment flows into the water, increasing the suspended matter in the water.

[0003] Existing sewage treatment devices usually directly transport sewage to a sewage pool, perform sedimentation treatment in the sewage pool, and then enter the sewage pool for centralized sedimentation, which makes the sedimentation time too long and cannot perform diversion sedimentation on the sewage entering the sewage pool, thereby greatly increasing the sedimentation time. At the same time, since the sewage consumes a long time in the sedimentation and separation process, the sewage treatment rate is affected. At the same time, when the sludge is collected, since there is a large amount of water in the sludge and the density of the sludge is relatively dense, the water will exist above the sludge, so that during the sludge discharge process, part of the water in the upper layer will also be discharged along with the sludge. Therefore, the present invention provides a separation and filtration device for sewage treatment. Summary of the invention

[0004] The main purpose of the present application is to provide a separation and filtration device for sewage treatment. Through the equally spaced water filter cartridges, it is convenient to break down the sewage into small pieces for treatment, thereby improving the treatment effect of the sewage. At the same time, during the sludge collection process, the water in the sludge is further filtered, thereby improving the treatment effect of the sewage.

[0005] To achieve the above-mentioned purpose, the present application provides a separation and filtration device for sewage treatment, comprising a separation box, wherein the interior of the separation box is sequentially provided with an upper chamber, a middle chamber and a lower chamber from top to bottom, and a mud guide plate is fixed between the upper chamber and the middle chamber, and a filter plate is slidably connected between the middle chamber and the lower chamber, a water filter cartridge is distributed in an array inside the upper chamber, and the bottom end of the water filter cartridge is extended to the interior of the middle chamber through the mud guide plate, and the top of the water filter cartridge is blocked by a closing plate, and a connecting port is opened on one side of the water filter cartridge above the closing plate, and the top of the closing plate is inclined, and a water inlet pipe is connected to the top of the closing plate; A mud guide cylinder is arranged at the edge of the water filter cylinder along the axial direction thereof, and the bottom end of the mud guide cylinder does not contact the bottom of the water filter cylinder, and an auger is rotatably connected inside the mud guide cylinder; A mud suction box is fixed inside the water filter cylinder on the side of the mud guide cylinder, and the side of the mud suction box away from the mud guide cylinder is open, and a piston baffle is slidably connected inside the mud suction box, a mud guiding port is opened at one end of the bottom of the mud suction box away from the mud guide cylinder, and a mud guiding channel connected to the mud guide cylinder is opened below the mud suction box, and filter holes 1 are opened at equal intervals at the bottom of the mud guiding channel, and filter holes 2 are opened at equal intervals on the side of the water filter cylinder outside the mud guide cylinder.

[0006] Preferably, an aeration matrix is ​​assembled at the bottom end of the interior of the lower chamber, and air outlet pipes are fixed at equal intervals on the top of the aeration matrix, and a cross-shaped fixing rod is fixed inside the air outlet pipe, and a rotating shaft is rotatably connected to the middle position of the cross-shaped fixing rod through a bearing, and a rotating blade is fixed at the bottom end of the rotating shaft, and a rotating disk is fixed on the top of the rotating shaft, and air outlet holes are opened on the rotating disk at equal intervals along its circumferential direction.

[0007] Preferably, the top of the water filter cartridge is connected to a sewage inlet disk, and the sewage inlet disks are connected by pipes to form a water flow channel, and a sewage inlet end is provided at one end of the water flow channel, the sewage inlet disk is rotatably connected to an impeller, and the rotating shaft of the impeller is fixed to the top of the auger, and a guide port connected to the water inlet pipe is provided at the inner bottom of the sewage inlet disk.

[0008] Preferably, the top surface of the mud guide plate is an inclined surface, so that the mud guide plate is distributed from high to low along the depth direction of the separation box, and a mud discharge port is opened on the back of the separation box at the lowest point of the mud guide plate.

[0009] Preferably, a discharge pipe is connected to the bottom of one side of the lower chamber, and a valve is installed on the discharge pipe.

[0010] Preferably, a small gear is fixedly connected to the top of the auger, and a crankshaft is also rotatably connected to the interior of the mud suction box, and a rotating rod is fixed on the crankshaft. One end of the rotating rod extends to the top of the water filter cylinder and is fixed with a large gear that meshes with the small gear, and a connecting rod is hinged between the crankshaft and the piston baffle.

[0011] The advantages of the present application are as follows: first, the sewage enters each sewage inlet disk in sequence through the pipeline, and enters the corresponding water filter cartridge at the same time, so as to divert the sewage, thereby facilitating the sewage treatment by breaking it into smaller pieces, thereby improving the sewage treatment effect. At the same time, the filling time between two adjacent water filter cartridges is different, and there is a time difference. Therefore, when the sewage is blocked in the flow direction of the water channel in the previous water filter cartridge, the other water filter cartridges can still treat the sewage, thereby maintaining a continuous sewage treatment process; Secondly, the rotation of the impeller drives the auger to rotate, thereby lifting the sludge entering the mud guide cylinder to the top of the water filter cylinder and entering the upper chamber from the connection port, and then discharged from the mud discharge port. In this process, the small gear and the large gear are engaged with each other, thereby driving the rotating rod to rotate, causing the crankshaft to rotate. During the rotation of the crankshaft, the connecting rod is used to pull the piston baffle to reciprocate inside the mud suction box, thereby opening and closing the mud guide port, so that the sludge settled at the bottom of the water filter cylinder enters the mud guide channel from the mud guide port, and uses the filter hole one to filter the sludge entering the mud guide channel, and the water in the sludge enters the middle chamber from the filter hole one, thereby improving the water in the sludge. The removal of sewage can improve the filtering effect. At the same time, since the number of teeth on the small gear is one third of the number of teeth on the large gear, the small gear needs to rotate three times for the large gear to rotate one circle. Therefore, to a certain extent, it gives the sewage time to settle, so that the sludge can have enough time to settle, preventing a large amount of water from entering the mud guide channel and being discharged together with the sludge during the sludge discharge process. At the same time, as the sludge accumulates at the bottom of the water filter cartridge, it will block the bottom of the water filter cartridge. Therefore, during the continuous injection of sewage, the pressure inside the water filter cartridge will gradually increase. Therefore, during the reciprocating movement of the piston baffle, the pressure inside the water filter cartridge will be relieved, so that the sludge settled at the bottom can be quickly discharged, thereby achieving the effect of anti-blocking. Finally, an external air source is used to provide the aeration matrix with the air source required for aeration. Then, when the gas is discharged from the outlet pipe, the rotating blades are driven to rotate, thereby synchronously using the rotating shaft to drive the rotating disk to rotate inside the outlet pipe. Then, the gas is discharged from the outlet hole. During the process of gas discharge, the gas rotates, causing the discharged gas to rise in a spiral shape, thereby improving the aeration effect on the sewage. BRIEF DESCRIPTION OF THE DRAWINGS

Filter holes 210 are evenly spaced on the side of the water filter cylinder 200 outside the mud guide cylinder 201. When in use, they are opened and closed through the mud guide port 208, so that the sludge settled at the bottom of the water filter cylinder 200 enters the mud guide channel 207 from the mud guide port 208, and the sludge entering the mud guide channel 207 is filtered by the filter hole 1 206, and the water in the sludge enters the middle chamber 120 from the filter hole 1 206, thereby improving the removal of water in the sludge and improving the filtering effect of sewage.

[0027] In this embodiment, an aeration matrix 400 is installed at the bottom end of the lower chamber 130, and an air outlet pipe 401 is fixed at equal intervals on the top of the aeration matrix 400, and a cross-shaped fixing rod 404 is fixed inside the air outlet pipe 401, and a rotating shaft 406 is rotatably connected to the middle position of the cross-shaped fixing rod 404 through a bearing, and a rotating blade 405 is fixed at the bottom end of the rotating shaft 406, and a rotating disk 403 is fixed on the top of the rotating shaft 406, and a rotating blade 405 is fixed on the rotating disk 403 along its circumferential direction. Air outlet holes 402 are provided at equal intervals. When in use, after the sewage enters the mud guide channel 130, the aeration matrix 400 is provided with the air source required for aeration through an external air source. Then, when the gas is discharged from the air outlet pipe 401, the rotating blades 405 are driven to rotate, so that the rotating disk 403 is driven to rotate inside the air outlet pipe 401 by the rotating shaft 406. Then, the gas is discharged from the air outlet holes 402. The gas is discharged in the process of rotation, so that the discharged gas rises in a spiral shape, thereby improving the aeration effect on the sewage.

[0028] like Figure 2 As shown, in the present embodiment, the top of the water filter cartridge 200 is connected with a sewage inlet disk 300, and the sewage inlet disks 300 are connected by pipes to form a water flow channel, and a sewage inlet end 301 is provided at one end of the water flow channel, the sewage inlet disk 300 is internally rotatably connected with an impeller 302, and the rotating shaft of the impeller 302 is fixed to the top of the auger 202, and a guide port 303 connected with the water inlet pipe 214 is provided at the bottom of the interior of the sewage inlet disk 300. When in use, the sewage enters one of the sewage inlet disks 300 from the sewage inlet end 301, thereby driving the impeller 302 to rotate, and then enters the interior of the water filter cartridge 200 from the guide port 303, and enters each sewage inlet disk 300 in turn through the pipe, and enters the corresponding water filter cartridge 200 at the same time, so as to divert the sewage, thereby facilitating the sewage to be processed in parts and improving the sewage treatment effect.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, in the present embodiment, the top surface of the mud guide plate 140 is an inclined surface, so that the mud guide plate 140 is distributed from high to low along the depth direction of the separation box 100, and a mud discharge port 111 is opened on the back of the separation box 100 at the lowest point of the mud guide plate 140. When in use, the inclined surface of the mud guide plate 140 is used to guide the sludge, and the sludge is discharged from the mud discharge port 111.

[0030] In this embodiment, a discharge pipe 131 is connected to the bottom of one side of the lower chamber 130 , and a valve is installed on the discharge pipe 131 . When in use, the treated sewage is discharged through the discharge pipe 131 .

[0031] like Figure 5 and Figure 7 As shown, in this embodiment, a pinion 212 is fixedly connected to the top of the auger 202, and a crankshaft 204 is also rotatably connected to the interior of the mud suction box 211, and a rotating rod 203 is fixed on the crankshaft 204. One end of the rotating rod 203 extends to the top of the water filter cartridge 200 and is fixed with a large gear 215 that meshes with the pinion 212, and a connecting rod 205 is hinged between the crankshaft 204 and the piston baffle 209. When in use, the pinion 212 and the large gear 215 are meshed with each other, thereby driving the rotating rod 203 to rotate, causing the crankshaft 204 to rotate, and during the rotation of the crankshaft 204, the connecting rod 205 is used to pull the piston baffle 209 to reciprocate inside the mud suction box 211.

[0032] In summary: First, the sewage enters one of the sewage inlet discs 300 from the sewage inlet end 301, thereby driving the impeller 302 to rotate, and then enters the inside of the water filter cartridge 200 from the guide port 303, and enters each sewage inlet disc 300 in turn through the pipeline, and enters the corresponding water filter cartridge 200 at the same time, so as to divert the sewage, thereby facilitating the sewage to be processed in parts, thereby improving the sewage treatment effect. At the same time, the filling time between two adjacent water filter cartridges 200 is different, and there is a time difference. Therefore, when the sewage is blocked in the flow direction of the water channel in the previous water filter cartridge 200, the other water filter cartridges 200 can still process the sewage, thereby maintaining a continuous operation of the sewage. After being filtered by the filter hole 210 on the filter water cartridge 200, the sewage enters the middle chamber 120, and then is filtered by the filter plate 150, and then is aerated by the aeration matrix 400 in the lower chamber 130, and then the treated sewage is discharged from the discharge pipe 131; When the sewage is inside the water filter cartridge 200, as the sludge in the sewage accumulates inside the water filter cartridge 200, it will settle at the bottom of the water filter cartridge 200. At the same time, the rotation of the impeller 302 drives the auger 202 to rotate, thereby lifting the sludge entering the mud guide cylinder 201 to the top of the water filter cartridge 200 and entering the upper chamber 110 from the connection port 213, and then discharged from the mud discharge port 111. In this process, the small gear 212 and the large gear 2 The connecting rod 205 is engaged with each other, thereby driving the rotating rod 203 to rotate, so that the crankshaft 204 rotates. During the rotation of the crankshaft 204, the connecting rod 205 is used to pull the piston baffle 209 to reciprocate inside the mud suction box 211, so as to open and close the mud guide port 208, so that the mud settled at the bottom of the water filter cartridge 200 enters the mud guide channel 207 from the mud guide port 208, and uses the filter hole 206 to enter the mud guide channel 207. The sludge is filtered, and the water in the sludge enters the interior of the middle chamber 120 from the filter hole 206, thereby improving the removal of water in the sludge and improving the filtering effect of the sewage. At the same time, since the number of teeth of the small gear 212 is one-third of the number of teeth of the large gear 215, the small gear 212 needs to rotate three circles before the large gear 215 rotates one circle. Therefore, to a certain extent, time is given to the sewage in the sedimentation process, so that the sludge can have enough time to settle, and prevent a large amount of water from entering the mud guide channel 207 and being discharged together with the sludge during the sludge discharge process. At the same time, as the sludge accumulates at the bottom of the water filter cartridge 200, it will block the 210 at the bottom of the water filter cartridge 200. Therefore, during the continuous injection of sewage, the pressure inside the water filter cartridge 200 will gradually increase. Therefore, during the reciprocating movement of the piston baffle 209, a pressure relief process will be generated inside the water filter cartridge 200, so that the sludge settled at the bottom can be quickly discharged, thereby achieving an anti-blocking effect; After the sewage enters the mud guiding channel 130, the aeration matrix 400 is provided with the gas source required for aeration through an external gas source, and then when the gas is discharged from the outlet pipe 401, the rotating blades 405 are driven to rotate, so that the rotating shaft 406 is synchronously used to drive the rotating disk 403 to rotate inside the outlet pipe 401, and then the gas is discharged from the outlet hole 402. During the process of gas discharge, the gas rotates, so that the discharged gas rises in a spiral shape, thereby improving the aeration effect on the sewage.
