Description

Technical Field

[0001] This utility model relates to the field of construction wastewater treatment, and in particular to a novel integrated wastewater treatment device for underground engineering and river engineering. Background Technology

[0002] my country is in a phase of rapid development, with construction projects such as building construction, road and bridge construction, tunnel construction, rail transit construction, and high-speed rail construction booming across the country. During these construction processes, a large amount of construction wastewater is generated. If discharged directly without treatment, it will negatively impact the environment. Construction wastewater includes foundation pit wastewater, construction seepage water, water-rich strata seepage, sand and gravel processing system wastewater, wastewater from washing construction machinery and transport vehicles, construction site and road cleaning, and concrete curing wastewater. Construction wastewater mainly contains inorganic pollutants, with relatively simple pollutant components, primarily mud and sand, high suspended solids content, and small amounts of ammonia nitrogen, petroleum hydrocarbons, etc., exhibiting relatively poor biodegradability. Because this type of wastewater has relatively high suspended solids (SS), and SS has a certain correlation with suspended COD and nitrogenous pollutants, physicochemical methods are recommended as the primary treatment process for construction wastewater. Super magnetic separation technology involves adding recyclable magnetic seeds to inert wastewater, forming magnetic flocs under the combined action of coagulants and flocculants, and then using the strong magnetic field generated by rare earth permanent magnet disks (the magnetic strength is more than 600 times its own weight) to achieve solid-liquid separation of wastewater in an instant (about 2 seconds), thereby eliminating most of the pollutants in the wastewater.

[0003] A utility model patent with authorization announcement number CN219002191U discloses a municipal river wastewater treatment device, relating to the field of wastewater treatment technology. It includes an impurity settling inlet located at the bottom of a treatment tank. A collection mechanism is located at the bottom of the impurity settling inlet, comprising a collection pipe fixed to the bottom of the treatment tank. A groove is formed on one side of the bottom of the collection pipe, and a sliding plate is installed inside the groove. The sliding plate is slidably connected to the collection pipe, and a sealing gasket is fixedly connected to one side of the sliding plate. A fixing block is fixedly connected to the middle of one side of the collection pipe. A limit pin is slidably connected through the fixing block and one side of the sliding plate. This utility model uses an electric telescopic rod to move a cleaning plate, which scrapes impurities from the surfaces of the coarse and fine filter screens, allowing them to enter the collection pipe through the impurity settling inlet, thus automatically cleaning the filter screens and saving manpower.

[0004] Analysis revealed that while the treatment device can easily clean the filter screen automatically, the filter screen still needs to be disassembled and replaced after prolonged use. However, the aforementioned treatment device is inconvenient to disassemble the filter screen, and when the filter screen is disassembled, the treatment device cannot continue to treat wastewater, which is not conducive to improving treatment efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a new integrated wastewater treatment device for underground engineering and river engineering, which solves the problems mentioned in the background.

[0006] To address the aforementioned technical problems, this utility model provides a novel integrated wastewater treatment device for underground engineering and river engineering, comprising a treatment tank with an inlet at the upper end and a drain pipe controlled by a valve at the lower end. An internal filter assembly is installed. A stirring blade is rotatably connected to the bottom of the treatment tank via a first rotating shaft. Two sets of treatment tanks are provided, with identical structures and side-to-side contact. The inlets of the two sets of treatment tanks are connected via a diversion pipe. A fan-shaped groove is provided at the top of the treatment tank to mate with the inlet. A fan-shaped plate is slidably connected inside the fan-shaped groove, and the fan-shaped plate has a drainage hole that mates with the inlet. The fan-shaped plate is driven by a second motor. The filter assembly is detachably connected to the treatment tank via bolts.

[0007] Furthermore, the filter assembly includes a filter screen, a slide groove, a slider, and a return spring. The slide groove is disposed on the side of the filter assembly and there are two sets of slide grooves. The filter screen is slidably connected to the slide groove through the slider. Each of the two sets of slide grooves is provided with two sets of return springs, and the two sets of return springs are respectively disposed on the upper and lower sides of the slider.

[0008] Furthermore, a first gear is provided at the upper end of the first rotating shaft, and a second rotating shaft is rotatably connected inside the processing barrel at the upper end of the first gear and the lower end of the filter assembly. A second gear is provided on the second rotating shaft, and the first gear meshes with the second gear. Cams are provided at both ends of the second rotating shaft, and the cams contact the lower surface of the filter assembly.

[0009] Furthermore, a rubber pad is fitted on the outer wall of the cam, and the cam contacts the filter assembly through the rubber pad.

[0010] Furthermore, the lower end of the first rotating shaft extends to the outside of the processing barrel and is connected to a driven wheel. A first motor is provided on the lower surface of the processing barrel, and a driving wheel is provided on the output shaft of the first motor. The driving wheel meshes with the driven wheel.

[0011] Furthermore, a sealing gasket is provided at the connection between the first rotating shaft and the processing tank.

[0012] Furthermore, guide grooves are provided on both sides of the filter assembly, and guide rods are provided inside the processing barrel in conjunction with the guide grooves.

[0013] Furthermore, a dosing pipe is connected to the side of the treatment tank, and the dosing pipe is located below the filter assembly.

[0014] The beneficial effects of this utility model are:

[0015] 1. Through the cooperation between the two sets of treatment tanks and the inlet, filter components, first rotating shaft, stirring blade, diversion pipe, second motor, fan-shaped groove, fan-shaped plate and drainage hole, when it is necessary to disassemble, repair or replace the filter screen on the treatment tank, it is only necessary to drive the second motor to drive the fan-shaped plate to rotate, so that the fan-shaped plate blocks the inlet, and the corresponding treatment tank will stop working. At this time, the other set of treatment tanks can still work normally, ensuring the continuity of wastewater treatment;

[0016] 2. Through the cooperation between the filter assembly, the second rotating shaft, the cam, the rubber pad, the filter screen, the slide groove, the slider and the return spring, when the second rotating shaft drives the cam to rotate, the cam will continuously push the filter screen to slide up and down in the filter assembly.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] like Figures 1 to 8 As shown, this utility model provides a novel integrated wastewater treatment device for underground engineering and river engineering, including a treatment tank 1. The upper end of the treatment tank 1 has an inlet 101, and the lower end is connected to a drain pipe controlled by a valve. A filter assembly 102 is installed inside. The bottom of the treatment tank 1 is rotatably connected to a stirring blade 104 via a first rotating shaft 103. Two sets of treatment tanks 1 are provided, and the two sets of treatment tanks 1 have the same structure and are side-fitted. The inlets 101 of the two sets of treatment tanks 1 are connected by a diversion pipe 2. Construction wastewater flows into the two sets of treatment tanks 1 through the diversion pipe 2 to complete the filtration treatment. A fan-shaped groove 202 is provided at the top of the treatment tank 1 to match the inlet 101. A fan-shaped plate 203 is slidably connected inside the fan-shaped groove 202. The fan-shaped plate 203 has a drainage hole 204 that matches the inlet 101. The fan-shaped plate 203 is driven by a second motor 201. In the default state, the drainage hole 204 on the fan-shaped plate 203 is... The flow hole 204 and the inlet 101 overlap vertically in space, allowing the engineering wastewater to flow normally into the two sets of treatment tanks 1. When maintenance is required on the filter assembly 102 of one set of treatment tanks 1, it is only necessary to control the rotation of the fan-shaped plate 203 so that the fan-shaped plate 203 completely covers the inlet 101. The filter assembly 102 is detachably connected to the treatment tank 1 by bolts. The lower end of the first rotating shaft 103 extends to the outside of the treatment tank 1 and is connected to the driven wheel 107. The lower surface of the treatment tank 1 is provided with a first motor 105. The output shaft of the first motor 105 is provided with a driving wheel 106, which meshes with the driven wheel 107. A sealing gasket 305 is provided at the connection between the first rotating shaft 103 and the treatment tank 1. The first motor 105 is not directly located at the lower end of the first rotating shaft 103, which can prevent the first motor 105 from being affected when the connection between the first rotating shaft 103 and the treatment tank 1 leaks.

[0029] like Figure 5-7As shown, the filter assembly 102 includes a filter screen 4, a slide groove 401, a slider 402, and a return spring 403. The slide groove 401 is located on the side of the filter assembly 102 and has two sets. The filter screen 4 is slidably connected to the slide groove 401 via the slider 402. Two sets of return springs 403 are installed in each of the two sets of slide grooves 401, respectively located on the upper and lower sides of the slider 402. A first gear 3 is installed at the upper end of the first rotating shaft 103. Inside the processing tank 1, a second rotating shaft 302 is rotatably connected between the upper end of the first gear 3 and the lower end of the filter assembly 102. A second gear 301 is provided on the second rotating shaft 302, and the first gear 3 meshes with the second gear 301. Cams 303 are provided at both ends of the second rotating shaft 302. Rubber pads 304 are sleeved on the outer wall of the cams 303. The cams 303 contact the filter assembly 102 through the rubber pads 304. When the first rotating shaft 103 rotates, it will synchronously drive the second rotating shaft 302 to start rotating, which in turn drives the cams 303 to rotate. With the cooperation of the slide groove 401, the slider 402 and the return spring 403, the filter screen 1 will continuously shake up and down, which can prevent the filter screen 4 from clogging.

[0030] like Figure 6 and Figure 8 The filter assembly 102 shown has guide grooves 404 on both sides. The treatment tank 1 has guide rods 405 inside that cooperate with the guide grooves 404. For ease of disassembly, the filter assembly 102 is detachably connected to the treatment tank 1 only at the contact point between the outer side and the treatment tank 1 by bolts. However, when engineering wastewater carrying sludge and debris falls, it will generate a huge impact force. The connection between the guide rods 405 and the filter assembly 102 can ensure the stability of the filter assembly 102. At the same time, when disassembling and removing the filter assembly 102, the guide rods 405 can also help the disassembly personnel to share some of the force, making the disassembly process more convenient.

[0031] like Figure 2 As shown, a dosing pipe 108 is connected to the side of the treatment tank 1. The dosing pipe 108 is located below the filter assembly 102. The filtration process can only initially remove impurities such as silt from the engineering wastewater. However, the engineering wastewater will still inevitably contain a large number of pollutants that cannot be removed by coarse filtration. Subsequently, super magnetic coagulant can be added to further purify the wastewater and make it meet the discharge standards. The dosing pipe 108 makes it convenient to add super magnetic coagulant to the engineering wastewater after coarse filtration. At the same time, the dosing pipe 108 is located below the filter assembly 102, which can prevent the coagulant from being absorbed by the debris on the filter screen 4 before entering the filtered wastewater.

[0032] Specifically, the engineering wastewater flows into the treatment tank 1 through the diversion pipe 2. After coarse filtration, a super magnetic coagulant is added to the engineering wastewater inside the treatment tank 1 through the dosing pipe 108. Under the action of the super magnetic coagulant, the impurities in the engineering wastewater that cannot be filtered will quickly form magnetic flocs. Then, the valve of the bottom drain pipe is opened to discharge the treated wastewater. The wastewater is separated from the super magnetic flocs by the super magnetic separator, thus obtaining a normal water source that has been deeply purified and meets the discharge standards. When maintenance is required on a certain group of treatment tanks 1, it is only necessary to close the corresponding inlet 101 through the fan-shaped plate 203.

[0033] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification but must be determined according to the claims.
