Description

Technical Field

[0001] This application relates to the field of sewage treatment. Specifically, it relates to a separation and filtration device for sewage treatment. Background Art

[0002] Among the water pollutions caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains a lot of pollutants and has a complex composition. 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, due to different production processes, the quality and quantity of the pollutants contained are also different. In addition to the wastewater discharged directly into the water body causing pollution, solid waste and waste gas can also pollute the water body. Agricultural pollution is mainly due to the loosening of the land surface during cultivation or land reclamation. When it rains before the soil and terrain are stable, a large amount of sediment flows into the water, increasing the suspended solids in the water.

[0003] Existing sewage treatment devices usually directly transport sewage to the sewage tank, and through sedimentation treatment in the sewage tank, and then enter the centralized sedimentation in the sewage tank, resulting in too long sedimentation time. It is impossible to perform split sedimentation on the sewage entering the sewage tank, thus greatly increasing the sedimentation time. At the same time, since the sewage takes a long time in the sedimentation and separation process, it affects the sewage treatment rate. At the same time, when collecting sludge, since there is a lot of water in the sludge and the density of the sludge is relatively high, the water will be above the sludge, so that when discharging the sludge, part of the water on the upper layer will also be discharged together 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 this application is to provide a separation and filtration device for sewage treatment. Through the equally spaced filter water cylinders, it is convenient to break up the sewage into small parts for treatment, improve the sewage treatment effect. At the same time, during the collection of sludge, the water in the sludge is further filtered, thereby improving the sewage treatment effect.

[0005] To achieve the above object, this application provides a separation and filtration device for sewage treatment, including a separation tank. Among them, an upper chamber, a middle chamber and a lower chamber are sequentially arranged in the separation tank from top to bottom. A mud guiding 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. The filter water cylinders are arranged in an array in the upper chamber, and the bottom ends of the filter water cylinders extend through the mud guiding plate into the middle chamber. The top of the filter water cylinder is blocked by a closing plate, and a connection port is opened on one side of the filter water cylinder above the closing plate. The top of the closing plate is inclined, and a water inlet pipe is connected to the top of the closing plate;

[0006] A mud guiding cylinder is arranged along the axial direction at the edge position inside the water filtering cylinder, and the bottom end of the mud guiding cylinder does not contact the bottom of the water filtering cylinder, and a screw conveyor is rotatably connected inside the mud guiding cylinder;

[0007] A mud suction box is fixed inside the water filtering cylinder on the side of the mud guiding cylinder, and the side of the mud suction box away from the mud guiding 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 guiding cylinder, and a mud guiding channel communicating with the mud guiding cylinder is opened below the mud suction box, and a first filter hole is equally spaced at the bottom of the mud guiding channel, and a second filter hole is equally spaced on the side of the water filtering cylinder outside the mud guiding cylinder.

[0008] Preferably, an aeration matrix is assembled at the bottom end inside the lower chamber, and air outlet pipes are equally spaced and fixed on the top of the aeration matrix. A cross-shaped fixing rod is fixed inside the air outlet pipe, and a rotating shaft is rotatably connected through a bearing at the middle position of the cross-shaped fixing rod. A rotating blade is fixed at the bottom end of the rotating shaft, and a rotating disc is fixed at the top of the rotating shaft, and air outlet holes are equally spaced along the circumferential direction on the rotating disc.

[0009] Preferably, the tops of the water filtering cylinders are all connected with sewage inlet discs, and the sewage inlet discs are connected through pipes to form a flowing water channel. A sewage inlet end is arranged at one end of the flowing water channel. An impeller is rotatably connected inside the sewage inlet disc, and the rotating shaft of the impeller is fixed to the top of the screw conveyor. A guiding port communicating with the water inlet pipe is opened at the bottom end inside the sewage inlet disc.

[0010] Preferably, the top surface of the mud guiding plate is an inclined surface, so that the mud guiding plate is distributed from high to low along the depth direction of the separation box, and a mud discharging port is opened at the back of the separation box at the lowest position of the mud guiding plate.

[0011] 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.

[0012] Preferably, a small gear is fixedly connected to the top of the screw conveyor. A crankshaft is also rotatably connected inside 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 filtering cylinder and is fixed with a large gear meshing with the small gear, and a connecting rod is hinged between the crankshaft and the piston baffle.

[0013] The advantages of the present application are as follows: First, the sewage enters each sewage inlet tray in sequence through a pipeline and simultaneously enters the corresponding water filtering cylinder, so as to divert the sewage, which is convenient for treating the sewage piecemeal, improving the treatment effect of the sewage. At the same time, due to the different filling times between adjacent two water filtering cylinders, there is a time difference. Therefore, when the previous water filtering cylinder is blocked in the flowing direction of the sewage in the flowing water channel, other water filtering cylinders can still treat the sewage, thus maintaining the continuous operation of the sewage treatment;

[0014] Second, during the rotation of the impeller, the auger is driven to rotate, so as to lift the sludge entering the mud guiding cylinder to the top of the water filtering cylinder and enter the inner part of the upper chamber from the connection port position, and then discharge it from the mud discharge port. During this process, since the small gear meshes with the large gear, the rotating rod is driven 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 in the sludge suction box, so as to open and close the mud guiding port, so that the sludge settling at the bottom of the water filtering cylinder enters the mud guiding channel from the mud guiding port, and the sludge in the mud guiding channel is filtered by the first filter hole, and the water in the sludge enters the inner part of the middle chamber from the first filter hole, thus improving the removal of water in the sludge and the filtering effect of the sewage. At the same time, since the number of teeth of the small gear is one-third of the number of teeth of the large gear, it is necessary for the small gear to rotate three circles for the large gear to rotate one circle. Therefore, to a certain extent, it gives time for the sewage to settle, enabling the sludge to have enough time to settle, preventing a large amount of water from entering the mud guiding channel and being discharged together with the sludge during the mud discharging process. At the same time, as the sludge accumulates at the bottom of the water filtering cylinder, it will block the bottom of the water filtering cylinder. Therefore, during the continuous injection of sewage, the pressure inside the water filtering cylinder will gradually increase. Therefore, during the reciprocating movement of the piston baffle, a pressure relief process will occur inside the water filtering cylinder, enabling the sludge settling at the bottom to be quickly discharged, thus achieving the anti-blocking effect;

[0015] Finally, an external air source provides the air source required for aeration for the aeration matrix. Then, when the gas is discharged from the air outlet pipe, the rotating blades are driven to rotate, and thus the rotating disk is synchronously driven to rotate inside the air outlet pipe by the rotating shaft. Then the gas is discharged from the air outlet holes. During the discharge of the gas, accompanied by rotation, the discharged gas rises in a spiral shape, thus improving the aeration effect of the sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See Figures 1 - 7As shown in the figure, this embodiment provides a separation and filtration device for sewage treatment, including a separation tank 100. Among them, an upper chamber 110, a middle chamber 120, and a lower chamber 130 are sequentially arranged in the separation tank 100 from top to bottom. A mud guide plate 140 is fixed between the upper chamber 110 and the middle chamber 120, and a filter plate 150 is slidably connected between the middle chamber 120 and the lower chamber 130. Filter water cylinders 200 are distributed in an array inside the upper chamber 110. The bottom end of the filter water cylinder 200 passes through the mud guide plate 140 and extends into the middle chamber 120. The top of the filter water cylinder 200 is blocked by a closing plate. A connection port 213 is opened on one side of the filter water cylinder 200 above the closing plate. The top of the closing plate is inclined, and a water inlet pipe 214 is connected to the top of the closing plate;

[0032] A mud guide cylinder 201 is arranged along the axial direction at the edge position inside the filter water cylinder 200, and the bottom end of the mud guide cylinder 201 does not contact the bottom of the filter water cylinder 200. A auger 202 is rotatably connected inside the mud guide cylinder 201;

[0033] A mud suction box 211 is fixed inside the filter water cylinder 200 on the side of the mud guide cylinder 201. One side of the mud suction box 211 away from the mud guide cylinder 201 is open. A piston baffle 209 is slidably connected inside the mud suction box 211. A mud guide port 208 is opened at one end of the bottom of the mud suction box 211 away from the mud guide cylinder 201. A mud guide channel 207 communicating with the mud guide cylinder 201 is opened below the mud suction box 211. Filter holes one 206 are equally spaced at the bottom of the mud guide channel 207. Filter holes two 210 are equally spaced on the side of the filter water cylinder 200 outside the mud guide cylinder 201. During use, the mud guide port 208 is opened and closed, so that the sludge settled at the bottom of the filter water cylinder 200 enters the mud guide channel 207 through the mud guide port 208, and the sludge entering the mud guide channel 207 is filtered by the filter holes one 206. The water in the sludge enters the middle chamber 120 through the filter holes one 206, thereby improving the removal of water in the sludge and the filtration effect of the sewage.

[0034] In this embodiment, an aeration matrix 400 is assembled at the inner bottom end of the lower chamber 130. Air outlet pipes 401 are fixedly arranged at equal intervals on the top of the aeration matrix 400. A cross-shaped fixing rod 404 is fixedly arranged inside the air outlet pipe 401. A rotating shaft 406 is rotatably connected to the middle position of the cross-shaped fixing rod 404 through a bearing. A rotating blade 405 is fixedly arranged at the bottom end of the rotating shaft 406. A rotating disk 403 is fixedly arranged at the top of the rotating shaft 406. Air outlet holes 402 are arranged at equal intervals along the circumferential direction of the rotating disk 403. During use, after the sewage enters the mud guiding channel 130, an external air source provides the air source required for aeration for the aeration matrix 400. Subsequently, when the gas is discharged from the air outlet pipe 401, the rotating blade 405 is driven to rotate, so as to synchronously drive the rotating disk 403 to rotate inside the air outlet pipe 401 by using the rotating shaft 406. Then the gas is discharged from the air outlet holes 402. During the process of gas discharge, with rotation, the discharged gas rises in a spiral shape, thereby improving the aeration effect on the sewage.

[0035] As Figure 2 shown, in this embodiment, sewage inlet disks 300 are connected to the tops of the water filtering cylinders 200. The sewage inlet disks 300 are communicated through pipelines to form a flowing water channel. A sewage inlet end 301 is arranged at one end of the flowing water channel. An impeller 302 is rotatably connected to the inside of the sewage inlet disk 300. The rotating shaft of the impeller 302 is fixed to the top of the auger 202. A guiding port 303 communicated with the water inlet pipe 214 is arranged at the inner bottom end of the sewage inlet disk 300. During use, sewage enters the inside of one of the sewage inlet disks 300 from the sewage inlet end 301, thereby driving the impeller 302 to rotate. Then it enters the inside of the water filtering cylinder 200 from the guiding port 303 and sequentially enters the inside of each sewage inlet disk 300 through pipelines, and at the same time enters the corresponding water filtering cylinder 200, so as to shunt the sewage, thereby facilitating the piecemeal treatment of the sewage and improving the sewage treatment effect.

[0036] As Figure 1 、 Figure 2 and Figure 5 shown, in this embodiment, the top surface of the mud guiding plate 140 is an inclined surface, so that the mud guiding plate 140 is distributed from high to low along the depth direction of the separation box 100. A sludge discharge port 111 is arranged on the back of the separation box 100 at the lowest position of the mud guiding plate 140. During use, the inclined surface of the mud guiding plate 140 is used to guide the sludge, and the sludge is discharged from the sludge discharge port 111.

[0037] In this embodiment, a discharge pipe 131 is connected to the bottom of one side of the lower chamber 130. A valve is installed on the discharge pipe 131. During use, the treated sewage is discharged through the discharge pipe 131.

[0038] As Figure 5 and Figure 7 shown, in this embodiment, a small gear 212 is fixedly connected to the top of the auger 202. A crankshaft 204 is also rotatably connected inside the sludge 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 filtering cylinder 200 and is fixed with a large gear 215 that meshes with the small gear 212. A connecting rod 205 is hinged between the crankshaft 204 and the piston baffle 209. During use, the rotation of the rotating rod 203 is driven by the meshing between the small gear 212 and the large gear 215, so that the crankshaft 204 rotates. During the rotation of the crankshaft 204, the piston baffle 209 is pulled by the connecting rod 205 to reciprocate inside the sludge suction box 211.

[0039] In summary:

[0040] First, sewage enters into one of the sewage inlet discs 300 from the sewage inlet end 301, thereby driving the impeller 302 to rotate. Then it enters into the interior of the water filtering cylinder 200 from the guiding port 303 and sequentially enters into each sewage inlet disc 300 through pipelines, and at the same time enters into the corresponding water filtering cylinder 200, so as to shunt the sewage, thus facilitating the piecemeal treatment of the sewage and improving the sewage treatment effect. At the same time, due to the different filling times between adjacent two water filtering cylinders 200, there is a time difference. Therefore, when the previous water filtering cylinder 200 in the flowing direction of the sewage in the flowing water channel is blocked, the other water filtering cylinders 200 can still treat the sewage, so as to maintain the continuous operation of the sewage. After the sewage is filtered through the second filter holes 210 on the water filtering cylinder 200, it enters into the middle chamber 120, and then is filtered through the filter plate 150, and then the sewage is aerated by the aeration matrix 400 inside the lower chamber 130, and then the treated sewage is discharged from the discharge pipe 131.

[0041] When the sewage is inside the water filter cylinder 200, as the sludge in the sewage accumulates inside the water filter cylinder 200, it will settle at the bottom of the water filter cylinder 200. At the same time, during the rotation of the impeller 302, the auger 202 is driven to rotate, so as to lift the sludge entering the inside of the mud guide cylinder 201 to the top of the water filter cylinder 200 and enter the inside of the upper chamber 110 from the connection port 213, and then be discharged from the sludge discharge port 111. During this process, since the small gear 212 meshes with the large gear 215, the rotating rod 203 is driven 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 sludge suction box 211, so as to open and close 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 filter hole one 206 is used to filter the sludge entering the mud guide channel 207, and the water in the sludge enters the inside of the middle chamber 120 from the filter hole one 206, so as to improve the removal of water in the sludge and improve 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 for the large gear 215 to rotate one circle. Therefore, to a certain extent, it gives time for the sewage to settle during the settlement process, so that the sludge can have enough time to settle, preventing 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 cylinder 200, the 210 at the bottom of the water filter cylinder 200 will be blocked. Therefore, during the continuous injection of sewage, the pressure inside the water filter cylinder 200 will gradually rise. Therefore, during the reciprocating movement of the piston baffle 209, a pressure relief process will occur inside the water filter cylinder 200, so that the sludge settled at the bottom can be quickly discharged, thus achieving the anti-blocking effect;

[0042] After the sewage enters the mud guide channel 130, an external air source is used to provide the air source required for aeration for the aeration matrix 400. Then, when the gas is discharged from the air outlet pipe 401, the rotating blade 405 is driven to rotate, so as to synchronously drive the rotating disk 403 to rotate inside the air outlet pipe 401 by the rotating shaft 406. Then the gas is discharged from the air outlet hole 402. During the discharge of the gas, accompanied by rotation, the discharged gas rises in a spiral shape, so as to improve the aeration effect of the sewage.
