Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water treatment, especially relates to a sedimentation tank for environmental protection water treatment. BACKGROUND

[0002] Environmental protection water treatment refers to removing or reducing harmful substances such as impurities, pollutants and pathogenic bacteria in water through physical, chemical or biological methods, so that water meets the needs of specific purposes, which not only ensures water quality safety and meets use standards to meet the needs of life, production and environment, but also reduces negative impacts on the environment by converting pollutants in water, realizes water purification and environmental protection. In the process of water treatment, a sedimentation tank is generally used, which can use gravity to make suspended particles in water settle to the bottom, thereby realizing solid-liquid separation, and is an indispensable part of the water resource purification process.

[0003] The existing sedimentation tank is generally used by first injecting sewage into the sedimentation tank. In order to promote the aggregation of suspended particles, a flocculating agent is generally added to the sewage. The sewage is left to stand, and the heavier particles sink to the bottom of the tank to form a sludge layer, thereby completing solid-liquid separation. The existing sedimentation tank needs to clean the sludge at the bottom every period of time. After the water is discharged, the sludge is dug out by manual and mechanical cooperation. However, due to the heavy weight of the sludge, the area to be cleaned is too large after the sludge falls to the bottom of the sedimentation tank, which consumes too much labor and time during cleaning. In order to solve the technical problem, the utility model provides a sedimentation tank for environmental protection water treatment. UTILITY MODEL CONTENTS

[0004] The main purpose of the utility model is to provide a sedimentation tank for environmental protection water treatment, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A sedimentation tank for environmental protection water treatment, comprising a shell, a guide plate is fixedly installed on the lower surface of the shell, an intercepting mechanism is arranged in the shell, a transmission mechanism is arranged on the side surface of the intercepting mechanism, an extension mechanism is arranged above the transmission mechanism, a power mechanism is arranged at the bottom of the guide plate, a spiral blade is arranged outside the power mechanism, the outer surface of the spiral blade is slidably connected with the inner wall of the guide plate, a fixed box is fixedly installed at the bottom of the guide plate, a sludge pumping pump is arranged on one side of the guide plate, and the input end of the sludge pumping pump is fixedly connected with the fixed box.

[0007] Preferably, a supporting rod is fixedly installed at the bottom of the shell, and a drain pipe is installed on one side of the shell.

[0008] Preferably, the interception mechanism includes a filter plate, and pins are provided at both ends of the filter plate, with the outer surface of the pins rotatably connected to the housing.

[0009] Preferably, the transmission mechanism includes a gear, one side of which is fixedly connected to a pin, and a toothed plate is meshed with the outer surface of the gear.

[0010] Preferably, both ends of the toothed plate are provided with stops, and one side of both the toothed plate and the stops is slidably connected to the housing.

[0011] Preferably, the telescopic mechanism includes a telescopic rod, the outer surface of which is fixedly connected to the housing, a connecting plate is fixedly connected to the telescopic end of the telescopic rod, and the lower surface of the connecting plate is fixedly connected to the toothed plate.

[0012] Preferably, the power mechanism includes an electric motor, the outer surface of which is fixedly connected to a guide plate, and a transmission rod is fixedly connected to the telescopic end of the electric motor. The outer surface of the transmission rod is rotatably connected to the guide plate, and the outer surface of the transmission rod is fixedly connected to a helical blade.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by incorporating components such as bolt blades and a sludge pump, the interception mechanism is adjusted to a horizontal and stationary state during sludge removal. The power mechanism drives the spiral blades to rotate, thereby agitating the solid particles at the bottom and causing them to form sludge with the water. This prevents the sludge from accumulating at the bottom of the guide plate and affecting its flowability. Simultaneously, the sludge is transported to the fixed box. Under the action of the sludge pump, the sludge inside the fixed box is extracted for easy cleaning, increasing cleaning efficiency and saving labor. This solves the problem that due to the weight of the sludge, the area to be cleaned after falling to the bottom of the sedimentation tank is too large, resulting in excessive labor and time consumption during cleaning.

[0015] In this invention, by setting up interception mechanisms and other components, after sedimentation, the filter plates are adjusted to a horizontal state and remain stationary. Multiple filter plates isolate the water inside the shell, isolate the sludge that has settled to the bottom below the filter plates, and isolate the clean water above the filter plates. The drain pipe is opened to drain the water above the filter plates. The filter plates isolate the sludge below, preventing the sludge from being carried out by the water during the flow.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-5 As shown, a sedimentation tank for environmental water treatment includes a shell 1. A guide plate 2 is fixedly installed on the lower surface of the shell 1. An interception mechanism 3 is provided inside the shell 1. The interception mechanism 3 includes a filter plate 301. Pins 302 are provided at both ends of the filter plate 301. The outer surface of the pins 302 is rotatably connected to the shell 1. The filter plate 301 is provided with filter holes, which can intercept garbage and solid particles in the water. The filter plate 301 can be rotated by the pins 302, so that the filter plate 301 is laid flat or stood up.

[0024] The interception mechanism 3 is provided with a transmission mechanism 4 on its side. The transmission mechanism 4 includes a gear 401. One side of the gear 401 is fixedly connected to the pin 302. The outer surface of the gear 401 is meshed with a toothed plate 402. When the toothed plate 402 moves horizontally, it can drive multiple gears 401 to rotate simultaneously, so as to drive the filter plate 301 to rotate and adjust the filter plate 301. Both ends of the toothed plate 402 are provided with a stop block 403. One side of the toothed plate 402 and the stop block 403 are slidably connected to the housing 1.

[0025] A telescopic mechanism 5 is provided above the transmission mechanism 4. The telescopic mechanism 5 includes a telescopic rod 501. The outer surface of the telescopic rod 501 is fixedly connected to the housing 1. A connecting plate 502 is fixedly connected to the telescopic end of the telescopic rod 501. The lower surface of the connecting plate 502 is fixedly connected to the toothed plate 402. By extending or shortening the telescopic rod 501, the connecting plate 502 can be driven to move horizontally, thereby driving the toothed plate 402 to move horizontally.

[0026] A power mechanism 6 is provided at the bottom of the guide plate 2. The power mechanism 6 includes a motor 601. The outer surface of the motor 601 is fixedly connected to the guide plate 2. The telescopic end of the motor 601 is fixedly connected to a transmission rod 602. The outer surface of the transmission rod 602 is rotatably connected to the guide plate 2. The outer surface of the transmission rod 602 is fixedly connected to the spiral blade 7. The motor 601 can drive the transmission rod 602 to rotate, thereby driving the spiral blade 7 to rotate, so as to transport the sludge to the fixed box 8.

[0027] The power mechanism 6 is equipped with a spiral blade 7 on its exterior. The outer surface of the spiral blade 7 is slidably connected to the inner wall of the guide plate 2. A fixed box 8 is fixedly installed at the bottom of the guide plate 2. A sludge pump 9 is installed on one side of the guide plate 2. The input end of the sludge pump 9 is fixedly connected to the fixed box 8. The lower part of the guide plate 2 is narrower than the upper part, and the cross-sectional shape of the lower part is semi-circular. When solid particles in the water sink downwards, they can fall onto the spiral blade 7 under the action of the guide plate 2. There are multiple interception mechanisms 3. Under the action of the transmission mechanism 4 and the telescopic mechanism 5, multiple interception mechanisms 3 can be moved to a horizontal state to separate the water inside the shell 1. The power mechanism 6 can drive the spiral blade 7 to rotate, thereby agitating the solid particles at the bottom and causing them to form sludge with the water, preventing them from accumulating at the bottom of the guide plate 2 and affecting its fluidity.

[0028] A support rod 10 is fixedly installed at the bottom of the housing 1, and a drain pipe 11 is installed on one side of the housing 1. The support rod 10 is used to support the guide plate 2. A valve is installed on the drain pipe 11 to control the flow and closure of the pipe. When the filter plate 301 moves to a horizontal state, the drain pipe 11 is just above the filter plate 301.

[0029] It should be noted that in actual use, the wastewater to be treated is injected into the interior of the shell 1, flocculant is added to the wastewater, and the telescopic rod 501 drives the toothed plate 402 to move horizontally back and forth, which in turn drives multiple gears 401 to rotate. The gears 401 drive the filter plate 301 to rotate around the pin shaft 302, so that the filter plate 301 moves alternately between horizontal and vertical states, thereby creating a stirring effect on the wastewater, so that the flocculant can be evenly integrated into the wastewater, thus achieving the effect of stirring the wastewater.

[0030] Adjust the filter plate 301 to a vertical position and let it stand still for a period of time. The solid particles in the wastewater will settle to the bottom of the guide plate 2. After the sedimentation is complete, adjust the filter plate 301 to a horizontal position and let it stand still. Multiple filter plates 301 isolate the water inside the shell 1, isolate the sludge that has settled to the bottom below the filter plate 301, and isolate the clean water above the filter plate 301. Open the drain pipe 11 to drain the water above the filter plate 301. The filter plate 301 isolates the sludge below to prevent the sludge from being carried out by the water during the flow.

[0031] After the clean water is discharged, turn on the motor 601 and the sludge pump 9. The motor 601 drives the spiral blades 7 to rotate, which agitates the solid particles at the bottom, causing them to form sludge with the water. This prevents the sludge from accumulating at the bottom of the guide plate 2 and affecting its flowability. At the same time, the sludge is transported to the fixed box 8. Under the action of the sludge pump 9, the sludge inside the fixed box 8 is extracted to facilitate the cleaning of the sludge inside, increasing the cleaning efficiency and saving labor.

[0032] The telescopic rod 501, the electric motor 601, and the sludge pump 9 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.

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.
