Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This application provides an energy-saving and environmentally friendly wastewater treatment device that solves the problems of garbage and debris in wastewater easily entering the filtration process, causing pipe blockage and affecting filtration efficiency, as well as the poor filtration efficiency of static filter screens.

[0028] The initial screening component filters out debris and waste in the wastewater, preventing it from entering subsequent filtration stages. Simultaneously, water flow and gravity automatically collect the debris. Combined with the first and second strainer screens 104 and 106, wastewater is smoothly discharged while debris is intercepted. The debris is collected in the collection frame 105 for easy periodic cleaning. The operation is simple. Secondly, the filtration components utilize centrifugal force to throw high-density impurities to the outside, achieving initial separation and improving filtration efficiency. Finally, the two strainer screens enable multi-stage fine filtration, significantly improving the quality of the effluent.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1 , Figure 2 and Figure 4 As shown, an energy-saving and environmentally friendly wastewater treatment device includes: an isolation box 1 for initially isolating garbage in the wastewater; an equipment box 2 installed on one side of the isolation box 1, with a filter box 3 fixedly installed on one side of the equipment box 2 for filtering the wastewater; a heating box 6 installed on one side of the filter box 3; and a primary screening assembly located inside the isolation box 1 for initially screening out large particles or garbage in the wastewater. The primary screening assembly includes: a mounting plate 102, a grid 103, and a collection frame 105. Two mounting plates 102 are installed inside the isolation box 1. A first slot is formed on the mounting plate 102, and the grid 103 is installed inside the first slot. 02 is connected to a placement rack on one side, and a collection frame 105 is provided inside the placement rack; a filter assembly is located inside the filter box 3 and is used to filter sewage. The filter assembly includes: a rotating plate 401, an arc plate 402, a first filter screen 403, a guide plate 404, and a second filter screen 405. The rotating plate 401 is rotatably connected inside the filter box 3. Two arc plates 402 are connected to the top of the rotating plate 401. A top plate is connected to the top of the two arc plates 402. The first filter screen 403 is provided between the two arc plates 402. The second filter screen 405 is connected between the top plate and the rotating plate 401. Multiple guide plates 404 are connected to the outside of the arc plate 402.

[0031] When treating sewage, the sewage contains a large amount of garbage and debris, which can easily affect the subsequent filtration efficiency and clog the pipes. At this time, the sewage can be discharged into the isolation box 1 through the sewage pipe 101. The garbage and debris in the sewage are isolated and filtered by the grid 103 in the primary screening component. The setting of two grids 103 can isolate and filter the garbage and debris to the maximum extent, preventing the garbage and debris from entering the subsequent filtration process. Then, the filtered sewage is pumped into the filter box 3 by the first water pump 201. The small particulate impurities in the sewage are filtered by the first filter screen 403 and the second filter screen 405 in the filter component.

[0032] Combination Figure 6 As shown, the mounting plate 102 is inclined, the bottom of the placement rack has a second slot, and a first strainer 104 is installed inside the slot. The bottom of the collection frame 105 has a third slot, and a second strainer 106 is installed inside the third slot.

[0033] When the debris is isolated on the grid 103, it moves towards the collection box 105 under the impact of the water flow and the inclined grid 103, and eventually falls into the collection box 105. The sewage in the collection box 105 can be discharged through the first strainer 104 and the second strainer 106, while the debris is isolated in the collection box 105. After a period of time, the collection box 105 can be removed from the isolation box 1 to clean the debris in the collection box 105.

[0034] Reference Figure 4 As shown, a sewage pipe 101 is connected to the top of the isolation box 1, a first water pump 201 is installed inside the equipment box 2, a first water pump 202 connected to the isolation box 1 is fixedly connected to one side of the first water pump 201, the bottom of the isolation box 1 is inclined towards the first water pump 202, and a drain pipe 203 is connected to the top of the first water pump 201, which is connected to the filter box 3.

[0035] After initial screening by the grid 103, the first water pump 201 pumps the sewage inside the isolation box 1 into the drain pipe 203 through the first water pumping pipe 202, and then injects it into the filter box 3 for filtration treatment through the drain pipe 203.

[0036] Reference Figure 4 and Figure 5 As shown, the bottom of the filter box 3 is connected to two symmetrically arranged drain pipes 301. A geared motor 4 is installed at the bottom of the filter box 3. The drive shaft at the top of the geared motor 4 is connected to the rotating plate 401. A sealed bearing is provided between the drive shaft and the filter box 3. Multiple guide plates 404 are evenly distributed in a ring array. The first filter screen 403 is a low-mesh filter screen with an arc structure, and the second filter screen 405 is a high-mesh filter screen with a cylindrical shape.

[0037] After the wastewater enters the filter box 3, the rotating plate 401 is driven to rotate by the geared motor 4. The rotating plate 401 drives the arc plate 402, the first filter screen 403, and the second filter screen 405 to rotate. At this time, the wastewater inside the filter box 3 is stirred and rotated by the multiple guide plates 404 on the arc plate 402, forming a vortex. Under the action of centrifugal force, the larger particles in the wastewater flow outward and accumulate on the outside. Then, the wastewater flows into the second filter screen 405 through the first filter screen 403 and the second filter screen 405 in sequence. The first filter screen 403 filters out small particles in the wastewater, while the second filter screen 405 filters out even finer particles.

[0038] Combination Figure 4 As shown, a second water pump 5 is installed on the top of the heating box 6. A three-way pipe 501 is connected to one side of the second water pump 5. A control valve is installed on the three-way pipe 501. One end of the three-way pipe 501 extends into the interior of the second filter screen 405 and has multiple through holes. The other end of the three-way pipe 501 is connected to an external water pipe.

[0039] During the rotation of the rotating plate 401, the control valve connects the second water pump 5 and the filter box 3 through the three-way pipe 501, so that the second water pump 5 draws the water filtered inside the second filter screen 405 into the heating box 6 through the three-way pipe 501.

[0040] When the first filter screen 403 and the second filter screen 405 need to be cleaned, the external water pipe can be connected to the three-way pipe 501 between the external water pipe and the filter box 3 through the control valve. This allows external clean water to be discharged into the filter box 3 through the three-way pipe 501 and sprayed out through multiple through holes to backwash the second filter screen 405 and the first filter screen 403. This prevents a large amount of particulate matter from adhering to the surface of the first filter screen 403 and the second filter screen 405 after long-term use, which would affect the flow rate of sewage through the filter screen and affect the filtration effect and efficiency. During the backwashing process, the drain pipe 301 can be opened to allow the cleaned sewage to be discharged through the drain pipe 301, which will also carry away the larger particles that were filtered earlier.

[0041] Reference Figure 4 As shown, a partition 601 is installed inside the heating box 6, which divides the heating box 6 into a heating chamber and an equipment chamber. A heater 602 is installed inside the equipment chamber, and a heating plate 603 is installed inside the heating chamber. The heater 602 is connected to the heating plate 603. Multiple heating rods 604 are connected to the top of the heating plate 603. The heating rods 604 are evenly distributed in a ring array. A water outlet pipe 605 is connected to the bottom of the partition 601. One end of the water outlet pipe 605 passes through the inside of the filter box 3.

[0042] The filtered water inside the filter box 3 is pumped into the heating box 6 by the second water pump 5 and injected into the heating chamber. Since water often contains various pathogenic microorganisms, such as bacteria, viruses, and parasites, high-temperature sterilization can effectively destroy the cell structure of these microorganisms, causing them to die or lose their reproductive ability. At this time, the heating plate 603 and heating rod 604 are energized by the heater 602, so that the heating plate 603 and heating rod 604 generate heat and heat the water in the heating chamber, sterilizing the filtered water at high temperature and improving water quality safety. The water sterilized by high temperature can be discharged to the outside through the water outlet pipe 605. Since the water outlet pipe 605 passes through the inside of the filter box 3, the heat of the high-temperature water inside the water outlet pipe 605 will be absorbed by the water inside the filter box 3, preheating the water inside the filter box 3, realizing heat recovery and utilization, and reducing energy consumption.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
