Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater sedimentation and filtration device. Background Technology
[0002] Wastewater refers to water generated during production, daily life, and other activities that has been polluted to a certain extent. Its physical, chemical, or biological properties have changed, making it unsuitable for its original purpose and requiring treatment before it can be reused or discharged.
[0003] Current wastewater sedimentation and filtration devices typically add flocculants from the top. This causes the flocculants to fall directly onto the top of the wastewater. When the wastewater at the top comes into contact with the flocculants, a large amount of flocculants are adsorbed by the wastewater, leading to excessive local flocculant accumulation. Meanwhile, the wastewater at the bottom experiences uneven contact with the flocculants, ultimately affecting the wastewater filtration effect. Utility Model Content
[0004] To overcome the problem that existing sedimentation and filtration devices cause excessive aggregation of flocculant at the top when flocculant is added from the top, resulting in uneven contact between the wastewater and flocculant at the bottom.
[0005] The technical solution of this utility model is: a sewage sedimentation and filtration device, including a stirring assembly, an additive assembly installed inside the stirring assembly, and a filter assembly connected to the right end of the stirring assembly; The mixing assembly includes a mixing tank connected to the outside of the adding assembly, a sewage pipe located at the front end of the top of the mixing tank, a mounting hole opened at the rear end of the top of the mixing tank, a fixing plate located at the top of the mixing tank, a motor installed in the middle of the fixing plate, a rotating rod connected to the bottom output shaft of the motor, a mixing rod located outside the rotating rod, and a water supply pipe located at the bottom of the mixing tank. The additive assembly includes an additive platform installed inside the mixing tank, a conveying chamber opened at the top of the additive platform, a placement pipe opened at the bottom of the conveying chamber, a nozzle installed on the placement pipe near the inside of the additive platform, and an additive pipe installed inside the mounting hole. The filtration assembly includes a filter box connected to the end of the water supply pipe away from the mixing tank, a connection hole in the middle of the top of the filter box, a placement hole in the front of the filter box, a filter plate installed inside the placement hole, a mounting plate in front of the filter plate, and a drain pipe in the middle of the bottom of the filter box.
[0006] Preferably, the bottom of the inner side of the mixing tank and the bottom of the inner side of the filter tank are both designed as conical inclined surfaces.
[0007] Preferably, the stirring rods are evenly distributed around the outside of the rotating rod.
[0008] Preferably, the placement tubes are evenly distributed circumferentially at the bottom of the delivery chamber, and the nozzles are evenly distributed linearly inside the placement tubes.
[0009] Preferably, the addition tube is connected to the nozzle through a delivery chamber and a placement tube.
[0010] Preferably, the filter plates are linearly and uniformly distributed, and the filtration effect is better as the filter plates move downwards.
[0011] The beneficial effects of this utility model are: This invention achieves layered delivery of flocculant by setting up an addition pipe, a delivery chamber, a placement pipe, and a nozzle. The flocculant is sprayed into the mixing chamber from nozzles at different heights, allowing the flocculant to come into contact with the wastewater at different heights, avoiding local aggregation, and ensuring that the wastewater and flocculant can be uniformly mixed inside the mixing chamber, thereby improving the wastewater filtration effect.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0015] A wastewater sedimentation and filtration device, according to Figures 1-4 As shown, it includes a stirring assembly 1, an additive assembly 2 installed inside the stirring assembly 1, and a filter assembly 3 connected to the right end of the stirring assembly 1. The mixing assembly 1 includes a mixing tank 101 connected to the outside of the adding assembly 2, a sewage pipe 102 located at the front end of the top of the mixing tank 101, a mounting hole 103 located at the rear end of the top of the mixing tank 101, a fixing plate 104 located at the top of the mixing tank 101, a motor 105 installed in the middle of the fixing plate 104, a rotating rod 106 connected to the bottom output shaft of the motor 105, a mixing rod 107 located outside the rotating rod 106, and a water supply pipe 108 located at the bottom of the mixing tank 101. The addition component 2 includes an addition platform 201 installed inside the mixing tank 101, a conveying chamber 202 opened at the top of the addition platform 201, a placement pipe 203 opened at the bottom of the conveying chamber 202, a nozzle 204 installed on the placement pipe 203 near the inside of the addition platform 201, and an addition pipe 205 installed inside the mounting hole 103. The filter assembly 3 includes a filter box 301 connected to the end of the water supply pipe 108 away from the mixing tank 101, a connection hole 302 opened in the middle of the top of the filter box 301, a placement hole 303 opened in the front end of the filter box 301, a filter plate 304 installed inside the placement hole 303, a mounting plate 305 set in the front end of the filter plate 304, and a drain pipe 306 set in the middle of the bottom of the filter box 301.
[0016] according to Figure 2 and Figure 4 As shown, the bottom inner side of the mixing tank 101 and the bottom inner side of the filter tank 301 are both designed with a conical inclined surface structure.
[0017] It should be noted that the guiding effect of the conical inclined surface allows the sewage inside the mixing tank 101 to converge towards the center along the inclined surface, thus allowing it to be discharged more smoothly from the water supply pipe 108, preventing sewage from accumulating at the bottom and improving drainage efficiency.
[0018] according to Figure 2 As shown, the stirring rods 107 are evenly distributed around the outside of the rotating rod 106.
[0019] It should be noted that when mixing wastewater and flocculant, the uniform circumferential distribution of the stirring rods 107 can improve the uniformity of mixing, avoid uneven flocculant concentration, and enhance the stirring intensity and stability, thus providing a stable environment for the formation of flocs.
[0020] according to Figure 3 As shown, the placement tube 203 is evenly distributed in a circular pattern at the bottom of the conveying chamber 202, and the nozzles 204 are evenly distributed in a linear pattern on the inner side of the placement tube 203.
[0021] It should be noted that by placing the pipe 203 and the nozzle 204, the flocculant can be delivered into the mixing tank 101 from different directions and heights, allowing the flocculant to quickly come into contact with and mix with the sewage, avoiding the problems of local aggregation or insufficient contact.
[0022] according to Figure 1 and Figure 3 As shown, the adding tube 205 is connected to the nozzle 204 through the delivery chamber 202 and the placement tube 203.
[0023] It should be noted that the addition pipe 205 and the nozzle 204 are connected, ensuring that the flocculant can enter the mixing zone stably and evenly.
[0024] according to Figure 4 As shown, the filter plates 304 are linearly and uniformly distributed, and the filtration effect is better as the filter plates 304 go lower.
[0025] It should be noted that the top filter plate 304 is a primary filter plate that only filters larger suspended solids; the two middle filter plates 304 are equipped with activated carbon to remove dissolved organic matter and odor molecules from the wastewater; and the bottom filter plate 304 uses a precision ceramic filter element to perform deep filtration of the wastewater.
[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
