Description

Technical Field

[0001] This application relates to the technical field of wastewater filtration devices, and in particular, to a wastewater filtration device. Background Art

[0002] Wastewater filtration devices are equipment used to treat and purify sewage, aiming to remove pollutants such as solid particles, suspended solids, organic matter, grease, and microorganisms in the sewage to meet discharge standards or reuse requirements. These devices are widely used in municipal sewage treatment plants, industrial wastewater treatment, agricultural drainage treatment, and other fields.

[0003] In order to master the water quality situation, a water quality detector needs to be used for detection. Due to a large amount of impurities in the sewage, the sampling pipe of the water quality monitor is frequently blocked, resulting in serious data lag and affecting the detection effect, which needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a wastewater filtration device to reduce the entry of impurities into the water quality monitor.

[0005] A wastewater filtration device provided by this application adopts the following technical scheme: It includes a filtration tank, the filtration tank is provided with a filtration chamber, the filtration tank is connected with a first partition board and a second partition board for separating the filtration chamber into a first sedimentation chamber, a second sedimentation chamber, and a third sedimentation chamber. The first partition board is provided with a first overflow hole, the second partition board is provided with a second overflow hole, the filtration tank is connected with a water inlet pipe communicating with the first sedimentation chamber and a water outlet pipe communicating with the third sedimentation chamber, and the water outlet pipe is connected with a filter.

[0006] By adopting the above technical scheme, the wastewater enters the first sedimentation chamber through the water inlet pipe, the impurities in the wastewater precipitate at the bottom of the first sedimentation chamber, the water level in the first sedimentation chamber rises, the wastewater passes through the first overflow hole and enters the second sedimentation chamber, the impurities in the wastewater precipitate again in the second sedimentation chamber, the water level in the second sedimentation chamber rises, the wastewater passes through the second overflow hole and enters the third sedimentation chamber, the impurities in the wastewater precipitate again in the third sedimentation chamber, and the wastewater undergoes multiple precipitations, thereby reducing the content of impurities in the wastewater. The water level in the third sedimentation chamber rises until it reaches the filter, and the filter filters the impurities in the wastewater, thereby reducing the impurities passing through the filter and entering the water outlet pipe, that is, reducing the impurities flowing into the water quality monitor.

[0007] Optionally, the inner wall of the first sedimentation chamber is connected with a baffle corresponding to the outlet of the water inlet pipe.

[0008] By adopting the above technical scheme, the water flowing out of the water inlet pipe collides with the baffle, thereby alleviating the water flow velocity. In the case of a slower water flow velocity, the impurities in the water are more likely to settle to the bottom, improving the efficiency of impurity precipitation.

[0009] Optionally, one side of the baffle plate close to the water inlet pipe is in the shape of an inner arc surface.

[0010] By adopting the above technical solution, the baffle plate can guide the water flow to flow along the inner arc surface, relieve the speed of the water flow, make the water flow more stable, and contribute to the precipitation of impurities.

[0011] Optionally, the filter tank is connected with three sewage pipes respectively corresponding to the first sedimentation chamber, the second sedimentation chamber and the third sedimentation chamber, and the sewage pipes are connected with control valves.

[0012] By adopting the above technical solution, manually open each control valve, so that the impurities accumulated in the first sedimentation chamber, the second sedimentation chamber and the third sedimentation chamber are discharged through the corresponding sewage pipes, reduce the content of suspended matters and other solids, and thus improve the water quality of the effluent.

[0013] Optionally, it further includes a controller, and the controller outputs a signal to the control valve.

[0014] By adopting the above technical solution, the controller can achieve automatic control, automatically open or close the control valve according to the preset time or conditions, reduce the need for manual operation, improve the convenience and accuracy of operation. By regularly discharging impurities, the content of impurities is reduced and the water quality is improved.

[0015] Optionally, two inclined plates are connected to the inner wall of the first sedimentation chamber, and the distance between the two inclined plates gradually decreases in the direction away from the water inlet pipe, and the inlet of the sewage pipe is located at the connection of the two inclined plates.

[0016] By adopting the above technical solution, the impurities move along the inclined surface of the inclined plate towards the connection of the two inclined plates under the influence of gravity, so that the impurities are gathered at the connection of the two inclined plates, which helps the impurities to pass through the sewage pipe and is convenient for cleaning the impurities.

[0017] Optionally, the first overflow hole and the second overflow hole are distributed in a staggered manner.

[0018] By adopting the above technical solution, the first overflow hole and the second overflow are distributed in a staggered manner, increasing the flow path of the water flow, increasing the residence time of the water flow in the second sedimentation chamber, which provides more time for the impurities to settle at the bottom of the second sedimentation chamber and improves the effect of impurity precipitation.

[0019] Optionally, the filter includes a filter pipe connected to the water outlet pipe and a filter net connected to the filter pipe, and the filter pipe is arranged vertically.

[0020] By adopting the above technical solution, the water level in the third precipitation chamber rises, and the filter screen filters impurities in the water, thereby reducing the entry of impurities into the filter pipe, that is, reducing the entry of impurities into the water quality monitor, which plays a role in protecting the water quality monitor.

[0021] Optionally, the filter box is provided with a relief groove communicated with the third precipitation chamber, and the filter box is rotatably connected with a cover plate for covering the relief groove.

[0022] By adopting the above technical solution, when a large amount of impurities adhere to the outer peripheral surface of the filter screen, the cover plate is opened to clean the impurities on the filter screen, thereby reducing the influence of impurities on the filtration of the filter screen. After the impurities on the filter screen are cleaned, the cover plate is closed to make the cover plate cover the relief groove, reducing the entry of dust into the third precipitation chamber through the cover plate.

[0023] Optionally, a support plate is connected to the inner wall of the relief groove, and the filter pipe is provided with a support groove for the support plate to pass through.

[0024] By adopting the above technical solution, the support plate plays a role in supporting the filter pipe, reducing the shaking of the filter pipe, thereby improving the stability of the filter pipe and facilitating the water to pass through the filter screen.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The water level in the third precipitation chamber rises until the water level reaches the filter. The filter filters impurities in the wastewater, thereby reducing the entry of impurities through the filter into the outlet pipe, that is, reducing the inflow of impurities into the water quality monitor.

[0027] 2. The water flowing out of the inlet pipe collides with the baffle, thereby alleviating the flow rate of the water. In the case of a slower water flow rate, the impurities in the water are more likely to settle to the bottom, improving the efficiency of impurity precipitation. BRIEF DESCRIPTION OF THE DRAWINGS

The control valve 61 is externally connected to a controller (not shown in the drawings). The signal output end of the controller is connected to the signal input end of the control valve 61.

[0040] Combined withFigure 2 and Figure 3 As shown, the first partition plate 2 is provided with a first overflow hole 21 connecting the first sedimentation chamber 111 and the second sedimentation chamber 112, and the first overflow hole 21 is located at one end of the first partition plate 2 away from the inclined plate 5; the second partition plate 3 is provided with a second overflow hole 31 connecting the second sedimentation chamber 112 and the third sedimentation chamber 113, and the second overflow hole 31 is located at one end of the second partition plate 3 away from the inclined plate 5.

[0042] The implementation principle of a wastewater filtration device in the embodiment of the present application is:

[0043] Before the wastewater enters the inlet pipe 12, that is, in the stage of wastewater treatment, larger solid particles, suspended matters and sediment in the wastewater are removed through a physical sieve or grille to reduce their entry into the inlet pipe 12. The wastewater enters the first sedimentation chamber 111 from the inlet pipe 12 and collides with the baffle 4, thereby alleviating the flow velocity of the water. In the case of a slower flow velocity, the impurities in the water are more likely to settle to the bottom, improving the sedimentation efficiency of the impurities. The water level in the first sedimentation chamber 111 rises, and the wastewater passes through the first overflow hole 21 and enters the second sedimentation chamber 112. The impurities in the wastewater are sedimented again in the second sedimentation chamber 112. The water level in the second sedimentation chamber 112 rises, and the wastewater in the second sedimentation chamber 112 passes through the second overflow hole 31 and enters the third sedimentation chamber 113. The impurities in the wastewater are sedimented again in the third sedimentation chamber 113. The wastewater undergoes multiple sedimentations, thereby reducing the content of impurities in the wastewater. The water level in the third sedimentation chamber 113 rises until the water level reaches the filter screen 72. The filter screen 72 filters the impurities in the wastewater, thereby reducing the entry of impurities into the outlet pipe 13. The water quality monitor detects the water quality in the outlet pipe 13, reducing the entry of impurities into the sampling pipe of the water quality monitor and playing a protective role for the water quality monitor.

[0046] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
