Description

Technical Field

[0001] This utility model relates to the field of wastewater purification and filtration technology, specifically to a multi-stage purification and filtration device for tailwater. Background Technology

[0002] Wastewater refers to water that is no longer used after being used or treated during various industrial production, agricultural activities, energy utilization, and daily life processes. It comes from industrial production processes such as chemical, electroplating, printing and dyeing, and papermaking industries. This wastewater usually contains a large amount of pollutants such as heavy metal ions, organic matter, and acid and alkali substances, and needs to be purified and filtered.

[0003] However, existing technologies still have many shortcomings in practical use, such as poor effluent treatment effect, inability to achieve multi-stage filtration to gradually remove impurities of different particle sizes in the effluent, and inability of the treatment equipment to timely remove residual suspended matter floating on the surface of the effluent, resulting in low practicality.

[0004] To address the aforementioned problems, the inventors have proposed a multi-stage effluent purification and filtration device. Utility Model Content

[0005] To address the problems of inconvenience in multi-stage filtration to gradually remove impurities of different particle sizes from effluent and the inconvenience in removing residual suspended matter floating on the surface of the effluent, the purpose of this utility model is to provide a multi-stage effluent purification and filtration device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-stage purification and filtration device for tailwater, comprising a housing, a cleaning device fixedly connected to the top of the housing, a mixing device provided inside the housing, the mixing device comprising a first rotating shaft symmetrically distributed, one end of the first rotating shaft being rotatably connected to one side inner wall of the housing, the other end of the first rotating shaft being fixedly connected to a sprocket, the sprockets being meshed with a chain, a first motor being fixedly connected to the lower part of the housing, the output end of the first motor being fixedly connected to the lower sprocket, a plurality of first bevel gears arranged in an equally spaced array fixedly sleeved on the outer surface of the first rotating shaft, two second bevel gears meshing with the outer surface of the first bevel gears, the ends of the second bevel gears being fixedly connected to a second rotating shaft, two hollow tubes being fixedly connected between the two side inner walls of the housing, blades being fixedly sleeved on the outer surface of the second rotating shaft, and a plurality of filter screens arranged in an equally spaced array fixedly connected to the inner wall of the housing.

[0007] As a preferred technical solution of this application, the cleaning device includes symmetrically distributed fixed slots, a lead screw rotatably connected between the inner walls of the two sides of one of the fixed slots, a second motor fixedly connected to one side of one of the fixed slots, the output end of the second motor extending into the fixed slot and fixedly connected to the lead screw, a guide rod fixedly connected between the inner walls of the two sides of the other fixed slot, a bracket slidably connected to the inner walls of the two fixed slots, a lower part of one side of the bracket threadedly connected to the lead screw, a lower part of the other side of the bracket movably connected to the guide rod, and a scraper fixedly connected to the lower inner wall of the bracket.

The lower part of one side of the bracket is threadedly connected to the lead screw, and the lower part of the other side is movably connected to the guide rod. When the lead screw rotates, due to the restriction of the guide rod, the bracket can only make linear reciprocating motion along the direction of the lead screw and the guide rod. The scraper fixedly connected to the lower inner wall of the bracket moves with the bracket, thereby achieving the goal of retrieval of residual suspended matter floating on the surface of the tailwater.

[0011] As a preferred technical solution of this application, the two adjacent second bevel gears are oriented in opposite directions.

[0012] Using the above technical solution, the two second rotating shafts will rotate in opposite directions.

[0013] As a preferred technical solution of this application, the outer surfaces of the two hollow tubes are respectively connected to multiple filter screens through the tubes.

[0014] Through the above technical solution, the tailwater flows under the stirring action of the blades and passes through the filter screens at different positions, which can achieve multi-stage filtration to gradually remove impurities of different particle sizes from the tailwater.

[0015] As a preferred technical solution of this application, both ends of the box are connected to water inlet pipes.

[0016] Using the above technical solution, the wastewater to be treated is introduced into the tank from the inlet pipe.

[0017] As a preferred technical solution of this application, a drain pipe is connected to one side of the box.

[0018] Through the above technical solution, the effluent after multi-stage purification and filtration is discharged from the tank through the drain pipe, meeting the discharge standards for purified effluent.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figure 1-4 As shown, this utility model provides a multi-stage purification and filtration device for tailwater, including a box 1, with inlet pipes 4 connected to both ends of the box 1, a drain pipe 5 connected to one side of the box 1, a cleaning device 3 fixedly connected to the top of the box 1, and a mixing device 2 provided inside the box 1.

[0030] The mixing device 2 includes symmetrically distributed first rotating shafts 201. One end of the first rotating shaft 201 is rotatably connected to the inner wall of one side of the housing 1, and the other end of the first rotating shaft 201 is fixedly connected to a sprocket 202. A chain 203 is meshed between the sprockets 202. A first motor 204 is fixedly connected to the lower part of the housing 1. The output end of the first motor 204 is fixedly connected to the lower sprocket 202. A plurality of first bevel gears 205 arranged in an equally spaced array are fixedly sleeved on the outer surface of the first rotating shaft 201. The outer surfaces of the first bevel gears 205 are meshed with each other. There are two second bevel gears 206, and the two adjacent second bevel gears 206 are in opposite directions. The first bevel gear 205 and the second bevel gear 206 are located inside the hollow tube 209. The end of the second bevel gear 206 is fixedly connected to a second rotating shaft 207. Two hollow tubes 209 are fixedly connected between the inner walls of the two sides of the housing 1. A blade 208 is fixedly sleeved on the outer surface of the second rotating shaft 207. Multiple filter screens 210 distributed at equal intervals are fixedly connected to the inner wall of the housing 1. The outer surfaces of the two hollow tubes 209 are respectively connected to the multiple filter screens 210 through.

[0031] The two second rotating shafts 207 rotate in opposite directions, and the blades 208 fixedly sleeved on the second rotating shafts 207 rotate accordingly, stirring and mixing the tailwater in the tank 1, creating favorable conditions for subsequent filtration and purification. The tailwater flows under the stirring action of the blades 208 and passes through the filter screens 210 at different positions, which can achieve multi-stage filtration to gradually remove impurities of different particle sizes in the tailwater.

[0032] The cleaning device 3 includes symmetrically distributed fixed slot plates 31. A lead screw 32 is rotatably connected between the inner walls of the two sides of one fixed slot plate 31. A second motor 34 is fixedly connected to one side of one fixed slot plate 31. The output end of the second motor 34 extends into the fixed slot plate 31 and is fixedly connected to the lead screw 32. A guide rod 33 is fixedly connected between the inner walls of the two fixed slot plates 31. A bracket 35 is slidably connected to the inner walls of the two fixed slot plates 31. The lower part of one side of the bracket 35 is threadedly connected to the lead screw 32, and the lower part of the other side of the bracket 35 is movably connected to the guide rod 33. A scraper 36 is fixedly connected to the lower inner wall of the bracket 35.

[0033] When the lead screw 32 rotates, due to the restriction effect of the guide rod 33, the bracket 35 can only make linear reciprocating motion along the direction of the lead screw 32 and the guide rod 33. The scraper 36 fixedly connected to the lower inner wall of the bracket 35 moves together with the bracket 35, which can salvage the residual suspended matter floating on the surface of the tailwater.

[0034] The working principle of the multi-stage purification and filtration device for tailwater in this embodiment is as follows: the tailwater to be treated is introduced into the housing 1 through the inlet pipe 4. Flocculant is poured into the housing 1, and the first motor 204 is started, driving the first rotating shaft 201 connected to it to rotate. Through the chain 203, another sprocket 202 is driven to rotate, thereby causing the other first rotating shaft 201 to rotate synchronously, realizing the transmission of power. Multiple filter screens 210 are arranged in equal intervals inside the housing 1. The outer surfaces of two hollow tubes 209 are connected to the multiple filter screens 210 through the tubes, providing support for the second rotating shaft 207 on the one hand, and allowing the tailwater to flow around the hollow tubes 209 on the other hand, increasing the contact area and filtration effect between the tailwater and the filter screens 210. The first rotating shaft The first bevel gear 205 on the outer surface of 201 rotates with the first rotating shaft 201. The second bevel gear 206, which meshes with the first bevel gear 205, starts to rotate under the drive of the first bevel gear 205. Since the two adjacent second bevel gears 206 are in opposite directions and are respectively connected to different second rotating shafts 207, the two second rotating shafts 207 will rotate in opposite directions. The blades 208, which are fixedly sleeved on the second rotating shafts 207, rotate accordingly, stirring and mixing the tailwater in the tank 1, creating good conditions for subsequent filtration and purification. The tailwater flows under the stirring action of the blades 208 and passes through the filter screens 210 at different positions, thereby achieving the purpose of multi-stage filtration to gradually remove impurities of different particle sizes in the tailwater.

[0035] The second motor 34 is started, and its output end drives the lead screw 32 to rotate in the fixed groove plate 31. The lower part of one side of the bracket 35 is threadedly connected to the lead screw 32, and the lower part of the other side is movably connected to the guide rod 33. When the lead screw 32 rotates, due to the restriction of the guide rod 33, the bracket 35 can only make linear reciprocating motion along the direction of the lead screw 32 and the guide rod 33. The scraper 36 fixedly connected to the lower inner wall of the bracket 35 moves together with the bracket 35, thereby achieving the purpose of retrieval of residual suspended matter floating on the surface of the tailwater.

[0036] After undergoing multi-stage purification and filtration, the effluent is discharged from the tank 1 through the drain pipe 5, meeting the discharge standards for purified effluent.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
