Description

Technical Field

[0001] This utility model relates to the field of greywater treatment technology, specifically to a greywater treatment and recycling device. Background Technology

[0002] Wastewater treatment technology is a water resource recycling technology that treats domestic or municipal sewage to meet non-drinking water standards and reuses it in specific scenarios. Its core lies in removing pollutants through physical, chemical, and biological methods to make the water quality between drinking water and sewage discharge standards. In terms of technology classification, physical treatment mainly uses membrane separation technology, such as ultrafiltration membranes, which can retain high molecular weight substances, colloids, and microorganisms to achieve efficient solid-liquid separation. Chemical treatment often uses a combination of coagulation sedimentation and activated carbon adsorption processes, removing suspended solids, phosphorus, and dissolved organic matter by adding agents. Biological treatment uses activated sludge processes, biological contact oxidation processes, etc., to decompose organic matter with the help of microorganisms, which is suitable for high-concentration sewage scenarios.

[0003] The current main method of treating sewage in society is to use the biochemical treatment method of sewage treatment plants to degrade the COD of sewage. After the COD meets the standards, it is discharged into the municipal sewage network. This method has two drawbacks: first, it lacks production cycle, resulting in water waste and lack of conservation; second, it increases the amount of municipal sewage to be treated, affecting the surrounding water resources and ecology. Therefore, we need a greywater treatment and recycling device. Utility Model Content

A drain pipe is provided on the side of the treatment tank away from the connecting pipe, and the drain pipe is used to connect the treatment tank and the sewage treatment station.

[0006] Preferably, a support leg is fixedly connected to the bottom of the treatment tank, a spray assembly is provided at the top of the treatment tank, and a stirring assembly is provided inside the treatment tank. The spray assembly includes a rack, which is fixed to the top of the treatment tank.

A conveying pipe is fixedly connected inside the half gear, and a nozzle is fixedly connected to the outer wall of the conveying pipe. The other end of the conveying pipe is connected to an external water source through a connecting hose. The treatment tank forms a rotating structure through the rack and half gear, and there are two half gears, with the two sets of teeth of the two half gears arranged in opposite directions.

[0007] Preferably, the treatment pool forms a rotating structure with the roller body through the roller groove, and the inner diameter of the roller groove matches the outer diameter of the roller body, and the inner wall of the roller groove is fitted to the outer wall of the roller body.

[0008] Preferably, the fixing frame forms a rotating structure with the conveying pipe through the mounting sleeve, and the inner wall of the mounting sleeve is fitted to the outer wall of the conveying pipe.

[0009] Preferably, the first motor forms a threaded structure through a screw and a threaded sleeve, and the outer diameter of the screw matches the inner diameter of the threaded sleeve, and the outer wall of the screw fits against the inner wall of the threaded sleeve.

[0010] Preferably, the stirring assembly includes a second motor, which is fixed to one side of the treatment tank. The output of the second motor is fixedly connected to a pulley via a coupling.

[0011] Preferably, the first pulley and the second pulley form a rotating structure through the second belt, and the second belt is disposed between the first pulley and the second pulley.

[0012] Preferably, the rotating rod has multiple stirring blades, and the multiple stirring blades are evenly spaced on the outer wall of the rotating rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the set-up treatment tank and circulating water pump, the treated wastewater can be recycled and mainly used for cleaning reactors, cooling pump bearings, and real-time water exchange between the smoothing tower and the washing tower in the production site. This solves the problem of wastewater discharge, which saves water consumption, reduces water waste, and avoids the impact of sewage discharge on the surrounding ecology. At the same time, the water exchange in the smoothing tower and the washing tower is more stable. Meanwhile, the wastewater after use is discharged to the sewage treatment plant. After biochemical treatment, the wastewater is treated to a qualified level and discharged into the treatment tank. The circulating pump next to the treatment tank transports the water back to the production site for recycling.

[0014] 2. By connecting to an external water source and delivering the pesticide to the delivery pipe via a flexible hose, the system works in conjunction with nozzles to achieve pesticide spraying. This solves the technical problem of uneven pesticide application. By starting the first motor, the screw rotates within the threaded sleeve, causing the mounting frame to move along the roller groove along the roller body on the mounting sleeve. Simultaneously, the mounting sleeve drives the half-gears at both ends of the delivery pipe to mesh with the rack in sequence, enabling the nozzles at the bottom of the delivery pipe to repeatedly swing and spray. This solves the technical problems of limited coverage and uneven spraying in traditional spraying methods, effectively improving the comprehensiveness and uniformity of pesticide spraying and enhancing the spraying effect. 3. By using a second motor and a transmission structure consisting of a pulley, a first belt, a first pulley, a second belt, and a second pulley, the rotating rod and stirring blades are driven to rotate. This structure solves the technical problems of low efficiency and insufficient mixing in traditional wastewater and chemical mixing methods. Driven by the second motor, the multi-stage belt drive stably and efficiently transmits power to the stirring blades, enabling them to strongly mix the chemicals and wastewater, thus significantly improving the wastewater treatment effect.

[0024] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, the stirring assembly 4 includes a second motor 401, which is fixed to one side of the treatment tank 1.

[0027] Working Principle: In use, the connecting hose 312 can be connected to an external water source, and the agent can be delivered into the delivery pipe 310. Spraying can then be achieved using the nozzle 311. Furthermore, by starting the first motor 309, the screw 308 can rotate, allowing it to rotate within the threaded sleeve 307. This allows the fixing frame 306 to move along the roller bodies 304 on the mounting sleeves 305 on both sides. The roller bodies 304 move along the roller grooves 302 at the top of the treatment tank 1. Simultaneously, the mounting sleeves 305 drive the half-gears 303 at both ends of the delivery pipe 310 to mesh with the rack 301 in sequence. The movement allows the nozzles 311 at the bottom of the conveying pipe 310 to repeatedly oscillate and spray, improving the spraying effect. In addition, by starting the second motor 401, the second motor 401 can drive the first belt 402 to rotate via the pulley, which in turn drives the first pulley 403 to rotate the second belt 404, which in turn drives the second pulley 405 to rotate. The second pulley 405 can then drive the rotating rod 406 to drive the stirring blades 407 to mix the agent and the wastewater, improving the water treatment effect and allowing the treated wastewater to be recycled.
