Description

Technical Field

[0001] This utility model relates to the field of treatment equipment, and more specifically, to a wastewater treatment device with solid-liquid separation effect. Background Technology

[0002] With the continuous progress of science and technology and society, human survival capabilities and living standards are constantly improving. As human activities become more active, the amount of wastewater generated in industry and daily life is also increasing year by year. In order to reduce the pollution of wastewater to the environment, we use wastewater treatment equipment to treat wastewater. As a key piece of equipment for modern urban environmental protection, wastewater processors are playing an increasingly important role. By efficiently treating wastewater, they transform wastewater into water that meets discharge standards, thus protecting water resources and the ecological environment.

[0003] A search revealed that Chinese patent CN221513690U discloses a "sewage treatment device with solid-liquid separation effect," comprising a sewage treatment tank and a discharge unit. The sewage treatment tank has evenly distributed partitions inside, an outlet pipe at the left end, a separation seat at the right end, a screen at the bottom, a water guide box at the right end of the lower surface, and an inlet pipe at the front end. The discharge unit includes a push plate, a slide seat, sliding columns, and a top cover. The slide seat is located inside the separation seat, and symmetrically distributed sliding columns are slidably connected inside. Each sliding column is fixedly connected to the upper surface of the top cover via a fixing block. A push plate is located at the left end of the lower surface of the top cover, and both the top cover and the push plate are slidably connected to the inner wall of the separation seat. This sewage treatment device with solid-liquid separation effect can automatically discharge solid impurities after solid-liquid separation, offering good ease of use. However, it still has the following drawbacks:

[0004] (1) The screen position of the inlet of the existing solid-liquid separation treatment equipment is fixed, and the position of the water flow into the screen is fixed, which causes the scale in the sewage to accumulate in one place, resulting in screen blockage and affecting the smoothness of subsequent separation.

[0005] (2) The existing solid-liquid separation box has a screen installed in the processing box by welding or multiple bolts. When cleaning and maintaining the screen, it is necessary to melt the weld or twist and disassemble multiple bolts, which brings inconvenience to maintenance.

[0006] Therefore, we have made improvements and proposed a wastewater treatment device with solid-liquid separation effect. Utility Model Content

[0007] The purpose of this invention is to address the problem that the fixed position of water flow into the screen leads to the accumulation of scale in one place, causing screen blockage, affecting subsequent separation, and making maintenance inconvenient by requiring the melting of welds or the loosening of multiple bolts.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A wastewater treatment device with solid-liquid separation effect is proposed to improve the above-mentioned problems.

[0034] like Figure 1-4 As shown, this embodiment proposes a wastewater treatment device with solid-liquid separation effect, including a treatment tank 1. A primary filter component is provided at the upper right side of the treatment tank 1, a separation component is provided inside the center of the treatment tank 1, and an outlet pipe 4 is installed at the left end of the treatment tank 1.

[0035] The primary filter assembly includes a top groove 201 opened on the upper right side of the treatment box 1. A panel 202 is movably arranged inside the top groove 201, and a mesh 203 is installed on the left end of the panel 202.

[0036] The separation component includes a slot 301 inside the processing box 1, a filter screen 302 is detachably inserted inside the slot 301, and an mounting plate 303 is installed on the upper end of the filter screen 302.

[0037] like Figure 3 As shown, a limiting groove 204 is provided on the right side of the top groove 201, and a limiting plate 205 is provided on the right side of the insert plate 202 to cooperate with the limiting groove 204. Under the limiting of the limiting plate 205 embedded in the limiting groove 204, the insert plate 202 moves back and forth in the top groove 201, which drives the strainer 203 to move back and forth. The position of the water inlet pipe is fixed, so that large-sized dirt in the sewage is evenly blocked by the strainer 203.

[0038] like Figure 3As shown, a bottom roller 206 is provided on the lower side of the panel 202. A motor 207 is connected to the side wall of the bottom roller 206. The motor 207 is controlled to rotate and drive the bottom roller 206 connected to it to rotate, so that they mesh relative to each other on the surface of the toothed plate 209. Under the limitation of the limiting plate 205 embedded in the limiting groove 204, the panel 202 moves back and forth in the top groove 201, which drives the strainer 203 to move back and forth. The position of the water inlet pipe is fixed, so that large-sized dirt in the sewage is evenly intercepted by the strainer 203, avoiding blockage caused by concentrated interception by the strainer 203.

[0039] like Figure 3 As shown, a bottom groove 208 is provided on the lower side of the top groove 201. A toothed plate 209 that cooperates with the bottom roller 206 is provided inside the bottom groove 208. The control motor 207 drives the bottom roller 206 connected to it to rotate, so that they mesh with each other on the surface of the toothed plate 209. Under the limitation of the limiting plate 205 embedded in the limiting groove 204, the insert plate 202 moves back and forth in the top groove 201.

[0040] like Figure 4 As shown, the mounting plate 303 has slots 304 on its front and rear sides. A pull plate 305 is provided inside the slots 304. Before the solid-liquid separation of sewage is required, the filter screen 302 is inserted downward into the box groove 301, and the pull plate 305 is pulled to make the clamping plate 306 slide into the slot 304, which compresses the spring rod 308 to make it contract.

[0041] like Figure 4 As shown, a retaining plate 306 is installed on the side of the pull plate 305 away from the center of the mounting plate 303. The front and rear sides of the box groove 301 are provided with retaining grooves 307 that cooperate with the retaining plate 306. When the retaining plate 306 is aligned with the retaining groove 307, the pulling force on the pull plate 305 is released, and the spring rod 308 pushes the pull plate 305 outward, so that the retaining plate 306 is inserted into the aligned retaining groove 307, thus completing the installation of the filter screen 302.

[0042] like Figure 4 As shown, a spring rod 308 is fitted on the side of the pull plate 305 away from the clamping plate 306. The spring rod 308 compresses and contracts the plate. When the clamping plate 306 is aligned with the slot 307, the pulling force on the pull plate 305 is released, and the spring rod 308 pushes the pull plate 305 outward, so that the clamping plate 306 is inserted into the aligned slot 307, completing the installation of the filter screen 302. After the initial solid-liquid separation by the strainer 203, the filter screen 302 separates the liquid through at least two layers of filter screens 302, achieving sufficient solid-liquid separation.

[0043] Specifically: When solid-liquid separation of wastewater is required, the control motor 207 rotates, driving the connected bottom roller 206 to rotate, causing it to mesh with the toothed plate 209. With the limiting plate 205 embedded in the limiting groove 204, the insert plate 202 moves back and forth within the top groove 201, causing the strainer 203 to move back and forth. The inlet pipe position is fixed, ensuring that large-sized dirt in the wastewater is evenly intercepted by the strainer 203, preventing blockage caused by concentrated interception and ensuring the continuity of solid-liquid separation. Before separation, insert the filter screen 302 downward into the slot 301, and at the same time pull the pull plate 305 to make the clamping plate 306 slide into the slot 304, and squeeze the spring rod 308 to make it contract. When the clamping plate 306 is aligned with the slot 307, release the pull force on the pull plate 305, and the spring rod 308 pushes the pull plate 305 outward, so that the clamping plate 306 is inserted into the aligned slot 307, completing the installation of the filter screen 302. After the initial solid-liquid separation by the strainer 203, the filter screen 302 is separated by at least two more layers of filter screens 302 to achieve full solid-liquid separation.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
