At this time, sewage treatment equipment is needed to purify the wastewater before discharge.

[0003] The sewage treatment process usually includes: pretreatment stage, primary treatment stage, intermediate treatment stage, deep treatment stage, disinfection and post-treatment, as well as sewage treatment residue treatment. The pretreatment stage is to remove large suspended particles and solid waste in the water by filtration. In the pretreatment stage, flocculants are often added to make large suspended particles in the sewage react and flocculate, so as to accelerate the sedimentation of large suspended particles in the sewage and achieve the purpose of rapid filtration.

[0004] After long-term use, the existing sewage treatment equipment will easily become clogged once various filtered impurities adhere to the surface of the filter plate, seriously affecting the sewage treatment efficiency; secondly, when adding flocculants to sewage, due to the effect of gravity, the flocculants are easy to precipitate and cannot fully contact and flocculate with the large suspended particles in the sewage, resulting in low utilization rate of the agent. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a sewage treatment device, which solves the problem that after long-term use of the existing sewage treatment equipment, the filter plate surface is easy to adsorb filtered impurities, causing the filter plate to be blocked, affecting the sewage treatment efficiency, and the added flocculant is easy to precipitate due to gravity, and cannot fully contact and react with the sewage, resulting in low utilization rate of the agent.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a sewage treatment device is provided, comprising: a box body, an injection mechanism, a rotation mechanism and a discharge mechanism, wherein the box body comprises a side plate, a top plate and a bottom plate;

[0007] The injection mechanism is arranged on the top plate, and includes a main pipe and a branch pipe, wherein the branch pipe is connected to the main pipe and the box body, and a drug injection port is also provided on the top plate;

[0008] The rotating mechanism is arranged in the box body, and includes a rotating shaft, a filter cartridge and rotating blades. The rotating shaft is connected to the top plate and the bottom plate respectively. One end of the rotating shaft passes through the top plate and extends in the direction away from the bottom plate inside the main pipe. The extended end of the rotating shaft is connected to a water wheel. The rotating shaft is fixedly connected to the filter cartridge and the rotating blades. The filter cartridge is fixedly connected to a rotating drum on the side close to the bottom plate. A scraper is fixedly installed on the side plate. The bottom surface of the scraper fits the inclined surface of the filter cartridge, and the length of the scraper is consistent with the length of the inclined surface of the filter cartridge.

[0009] The discharge mechanism is arranged on the bottom plate, and comprises a drainage pipe for draining water and a collection box for collecting large particle suspended matter and solid waste.

[0010] Preferably, the filter cartridge is of an inverted funnel shape, and the bottom surface of the rotating cartridge is in contact with the bottom plate.

[0011] Preferably, the drainage pipe is arranged within the projection range of the filter cartridge on the bottom plate, and the collection box is located outside the projection range of the filter cartridge on the bottom plate.

[0012] Preferably, a control valve is installed on the drain pipe, and a sealing cover is installed on the collection box.

[0013] Preferably, bearings are provided at the connection points between the rotating shaft and the top plate and the bottom plate.

[0014] Preferably, the rotating blades are located between the filter cartridge and the top plate.

[0015] Preferably, the filter cartridge is in the shape of a truncated cone, and the diameter of the bottom surface of the filter cartridge is the same as the diameter of the rotating drum.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 4 As shown, a sewage treatment device comprises a box body 1, wherein the box body 1 comprises a side plate 11, a top plate 12 and a bottom plate 13, wherein an injection mechanism 2 is fixedly arranged on the top plate 12, and a discharge mechanism 4 is fixedly arranged on the bottom plate 13, and a rotating mechanism 3 is arranged inside the box body 1, and the rotating mechanism 3 is located between the top plate 12 and the bottom plate 13;

[0027] The injection mechanism 2 includes a main pipe 21 and at least one branch pipe 22. The main pipe 21 is fixedly connected to the top plate 12. One end of the branch pipe 22 is connected to the main pipe 21, and the other end passes through the top plate 12 and extends to the inside of the box body 1. The top plate 12 is also provided with a drug injection port 23.

[0028] The rotating mechanism 3 comprises a rotating shaft 31, a filter cartridge 34 and a rotating drum 35. One end of the rotating shaft 31 is rotatably connected to the bottom plate 13, and the other end passes through the top plate 12 and extends in the direction away from the bottom plate 13 inside the main pipe 21, wherein bearings are provided at the connection between the rotating shaft 31 and the bottom plate 13 and the top plate 12; a water wheel 32 is fixedly installed at the end of the rotating shaft 31 away from the bottom plate 13; the filter cartridge 34 is arranged on the rotating shaft 31, one end of the filter cartridge 34 is fixedly connected to the rotating shaft 31, and the other end is fixedly connected to the rotating drum 35; it should be noted that the filter cartridge 34 is an inverted funnel shape, and the lower bottom surface of the rotating drum 35 is in contact with the bottom plate 13;

[0029] The rotating shaft 31 is also provided with at least one rotating blade 33, which is located between the filter cartridge 34 and the top plate 12. At least one scraper 5 is fixedly connected to the side plate 11. The scraper 5 is inclined along the rotating drum 35 toward the rotating shaft 31 and fits the surface of the filter cartridge 34. At the same time, the length of the scraper 5 is consistent with the length of the inclined surface of the filter cartridge 34.

[0030] Through the linkage cooperation of the injection mechanism 2 and the rotation mechanism 3, after the sewage is injected from the main pipe 21, it enters the box body 1 through the branch pipe 22. At the same time, the water wheel 32 starts to rotate due to the impact of the sewage, driving the rotating shaft 31 and the filter cartridge 34 to rotate synchronously. At this time, the filter cartridge 34 filters the sewage, and the solid waste in the sewage is filtered by the filter cartridge 34. The filtered sewage enters the inside of the filter cartridge 34. Since the filter cartridge 34 keeps rotating, the sewage can be evenly sprayed on the filter cartridge 34 after entering the inside of the box body 1 from the branch pipe 22, and will not be concentrated on a certain place on the filter cartridge 34, thereby increasing the use area of ​​the filter cartridge 34 and delaying the clogging of the filter cartridge 34. At the same time, when the sewage is sprayed from the branch pipe 22 to the filter cartridge 34, because the surface of the filter cartridge 34 is The inclined design allows the sewage to flush the filter cartridge 34 and flush away the solid waste attached to the filter cartridge 34. When the solid waste attached to the filter cartridge 34 increases, the scraper 5 provided on the side plate 11 cleans the rotating filter cartridge 34. At the same time, since the rotating shaft 31 is provided with rotating blades 33, the rotating shaft 31 rotates and drives the rotating blades 33 to rotate synchronously. When the sewage exceeds the filter cartridge 34, the flocculant is added from the dosing port 23 and contacts and reacts with the large suspended particles in the sewage, the rotating blades 33 stir the sewage in the box 1, so that the sewage inside the box 1 remains in a flowing state, prolongs the sedimentation time of the flocculant, allows the flocculant to react more fully, and enhances the flocculation effect. Finally, the large suspended particles after flocculation are filtered by the filter cartridge 34.

[0031] like Figure 5-Figure 6As shown, the discharge mechanism 4 includes a drain pipe 41, a collection box 43 and a plurality of bolts 45. The drain pipe 41 and the collection box 43 are fixedly mounted on the bottom plate 13. The drain pipe 41 and the collection box 43 are connected to the inside of the box body 1. A control valve 42 is mounted on the drain pipe 41. The collection box 43 is movably connected to a sealing cover 44 through bolts 45. It should be noted that the drain pipe 41 is located within the projection range of the filter cartridge 34 on the bottom plate 13, and the collection box 43 is located outside the projection range of the filter cartridge 34 on the bottom plate 13. The filtered sewage is discharged from the drain pipe 41, and the filtered large suspended matter and solid waste are cleaned by the scraper 5 and then precipitated into the collection box 43 due to gravity. When the sewage treatment work is completed, the sealing cover 44 is opened to clean the sediment in the collection box 43.

[0032] The bottom plate 13 is also provided with support legs 6, through which the sewage treatment equipment is stably supported on the working surface.

[0033] The working principle of the utility model is as follows: during operation, sewage enters from the main pipe 21, then flows through the branch pipe 22 into the interior of the housing 1, and large suspended particles and solid waste in the sewage are filtered by the filter cartridge 34 and attached to the filter cartridge 34 or precipitated into the collection box 43; when the sewage passes through the water wheel 32, the water wheel 32 is washed and starts to rotate, thereby driving the rotation of the rotating shaft 31, and the filter cartridge 34 arranged on the rotating shaft 31 starts to rotate synchronously, and the scraper 5 arranged on the side plate 11 cleans the filter cartridge 34, and the cleaned large suspended particles and solid waste are precipitated into the collection box 43; when the water level exceeds the filter cartridge 34, the flocculant is added from the dosing port 23, and the rotating blades 33 stir the sewage, so that the flocculant and the large suspended particles in the sewage are fully contacted and reacted, and the large suspended particles after flocculation are filtered and then precipitated into the collection box 43; when the work is completed, the control valve 42 is opened, and the filtered sewage is discharged from the drain pipe 41. When there are many filtered objects in the collection box 43, the sealing cover 44 is opened by rotating the bolt 45, so as to clean the collection box 43.
