Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater filtration device for water pollution prevention and control. Background Technology

[0002] Wastewater refers to polluted water generated by human activities. It usually contains harmful substances or pollutants and needs to be treated before it can be safely discharged or reused. Wastewater needs to be filtered during treatment, so filtration devices are required.

[0003] The wastewater filtration device for water pollution prevention disclosed in publication number "CN219950793U" includes a device shell, a filter chamber and a first filter screen. A sewage inlet is opened at the upper end of the device shell. The first filter screen is set at the upper end of the device shell. Fixed frames are connected to both sides of the first filter screen. An ultrasonic reactor is set at the lower end of the first filter screen. Ultrasonic generators are set on the left and right sides of the ultrasonic reactor. A plate transducer is set inside the ultrasonic generator. A second filter screen is set at the lower end of the ultrasonic generator.

[0004] Traditional wastewater filtration devices lack the function of automatically cleaning foreign objects from the filter. When too many foreign objects accumulate on the filter screen, it affects the flow of wastewater and the filtration quality. Furthermore, the activated carbon filter structure lacks a quick-replacement function, requiring the device to be shut down when the activated carbon is saturated, thus affecting the normal treatment of wastewater and reducing the filtration efficiency. Therefore, we have designed a wastewater filtration device for water pollution control to solve these problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater filtration device for water pollution prevention and control, which solves the problems of not being able to automatically clean foreign objects under the filter on the bar screen, thus affecting the wastewater throughput efficiency and filtration quality, and not being able to quickly replace the activated carbon structure.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a wastewater filtration device for water pollution prevention and control, comprising a filter box and a first filtration mechanism assembled on the front side inside the filter box, and a second filtration mechanism assembled on the rear side inside the filter box.

[0007] A water inlet pipe is fixedly installed on the front of the filter box, and a drain pipe is fixedly installed on the back of the filter box.

[0008] The first filtration mechanism includes a mounting base for mounting the bottom of the filter box. A grid bar is fixedly mounted at equal intervals on the top of the mounting base.

A collar is fixedly mounted on the back of each lifting seat. An installation rod is rotatably mounted inside the collar. Cleaning rods inserted into the grid bar are fixedly mounted at equal intervals on the front of each installation rod. A drive motor is fixedly mounted on the top of each lifting box. The output end of each drive motor extends into the lifting box and is fixedly mounted with a lifting screw. A collection box for use with the cleaning rod is fixedly mounted inside the filter box behind the grid bar. An adjustment plate is fixedly mounted on one end of each installation rod.

[0009] The second filtration mechanism includes a mounting frame installed inside the filter box. Multiple activated carbon boxes are slidably installed inside the mounting frame, and mesh plates are fixedly installed on the front and back of each activated carbon box.

[0010] Preferably, a push plate is slidably installed inside the collection box, and a transverse screw is rotatably installed inside the filter box on the back of the collection box. The transverse screw is threadedly connected to the back of the push plate, and one end of the transverse screw passes through the filter box and is fixedly installed with a handwheel.

[0011] Preferably, the bottom of the collection box has drainage holes at equal intervals.

[0012] Preferably, the mounting bracket has a groove on its front side, a water-cutting plate is slidably installed inside the groove, and an operating rod is fixedly installed on the top of the front side of the water-cutting plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, this embodiment proposes a wastewater filtration device for water pollution control, including a filter box 1, a first filtration mechanism 2 assembled on the front side inside the filter box 1, and a second filtration mechanism 3 assembled on the rear side inside the filter box 1. An inlet pipe 101 is fixedly installed on the front of the filter box 1, and a drain pipe 102 is fixedly installed on the back of the filter box 1. The first filtration mechanism 2 includes a mounting base 202 installed on the bottom of the filter box 1. Grille bars 206 are fixedly installed at equal intervals on the top of the mounting base 202. Lifting boxes 201 are fixedly installed on both sides of the top of the mounting base 202, and lifting mechanisms are slidably installed inside the lifting boxes 201. The lowering seat 203 and the lifting seat 203 are both fixedly installed with collars 207. The collars 207 are rotatably installed with mounting rods 208. The front of the mounting rods 208 are fixedly installed with cleaning rods 209 that are inserted into the grille bar 206. The top of the lifting box 201 is fixedly installed with drive motors 205. The output end of the drive motors 205 extends into the lifting box 201 and is fixedly installed with lifting screws 204. The filter box 1 on the rear side of the grille bar 206 is fixedly installed with a collection box 4 that works with the cleaning rods 209. One end of the mounting rod 208 is fixedly installed with an adjusting plate 2010.

[0029] In use, the inlet pipe 101 is connected to an external wastewater pipe, allowing wastewater to enter the filter box 1. The mounting base 202 can mount the grid rods 206 on the front side inside the filter box 1. The grid rods 206 can filter and intercept larger foreign objects and debris in the wastewater. The drive motor 205 drives the lifting screw 204 to rotate inside the lifting box 201. When the lifting screw 204 rotates, it can lift the lifting seat 203 and the collar 207. Simultaneously, the mounting rod 208 and the cleaning rod 209 inside the collar 207 rise. The cleaning rod 209 is inserted between the grid rods 206, thus lifting the foreign objects and debris filtered by the grid rods 206, achieving automatic removal of debris from the filter element of the grid rods 206. The cleaning function ensures the smooth flow of wastewater through the bar screen 206 and prevents excessive accumulation of debris on the bar screen 206, which could affect the filtration quality. When the mounting rod 208 and cleaning rod 209 are raised below the collection box 4, the adjusting plate 2010 contacts the collection box 4. The contact between the adjusting plate 2010 and the bottom of the collection box 4 allows the mounting rod 208 to rotate. After rotation, the mounting rod 208 can flip the debris and foreign objects on the cleaning rod 209 into the collection box 4, thus enabling the recycling of debris on the cleaning rod 209. A reset torsion spring is fitted at one end of the cleaning rod 209. When the mounting rod 208 and cleaning rod 209 are lowered, the reset torsion spring can reset and rotate the cleaning rod 209 back to a horizontal position, facilitating the reuse of the cleaning rod 209.

[0030] Example 2

[0031] Based on Example 1, such as Figure 2 , Figure 4 and 5 As shown, the second filtration mechanism 3 includes a mounting bracket 301 installed inside the filter box 1. Multiple activated carbon boxes 302 are slidably installed inside the mounting bracket 301. Mesh plates 303 are fixedly installed on the front and back of the activated carbon boxes 302.

[0032] In use, the mounting bracket 301 is fixedly installed inside the rear side of the filter box 1, and the activated carbon box 302 is slidably installed inside the mounting bracket 301 at equal distances. The activated carbon box 302 is filled with activated carbon. The mesh plate 303 can intercept the front and back of the activated carbon box 302, so that the activated carbon box 302 can adsorb and filter small foreign objects in the wastewater. When the activated carbon inside the activated carbon box 302 is saturated, the staff can pull it out and replace it, thereby improving the convenience of the staff when replacing the activated carbon box 302 and avoiding the need to shut down the device when replacing the activated carbon box 302, thus improving the speed of the staff when maintaining the device.

[0033] like Figure 2 and Figure 5 As shown, a push plate 402 is slidably installed inside the collection box 4, and a transverse screw 403 is rotatably installed inside the filter box 1 on the back of the collection box 4. The transverse screw 403 is threadedly connected to the back of the push plate 402, and one end of the transverse screw 403 passes through the filter box 1 and is fixedly installed with a handwheel 404.

[0034] In use, the horizontal screw 403 can be rotated to move the push plate 402 inside the collection box 4. The movement of the push plate 402 can push the garbage and foreign objects collected inside the collection box 4 to one side, and the garbage is discharged through the opening on the filter box 1. The handwheel 404 makes it easy for the staff to rotate the horizontal screw 403.

[0035] like Figure 3 and Figure 6 As shown, the bottom of the collection box 4 has drainage holes 401 at equal intervals.

[0036] When in use, the drain hole 401 can drain the garbage collected on the collection box 4, avoiding the situation where the garbage contains a lot of wastewater when it is discharged.

[0037] like Figure 5 As shown, the mounting bracket 301 has a sliding groove 306 on its front side, and a water intercepting plate 307 is slidably installed inside the sliding groove 306. An operating rod 308 is fixedly installed on the top of the front side of the water intercepting plate 307.

[0038] When in use, when the staff pulls the activated carbon box 302 out of the mounting bracket 301, the staff inserts the water intercepting plate 307 into the slide groove 306, so that the mounting bracket 301 can be closed when the activated carbon box 302 is pulled out, thus preventing the wastewater from being discharged without being filtered by activated carbon. The operating rod 308 facilitates the staff's operation of installing and pulling out the water intercepting plate 307.

[0039] like Figure 5 As shown, lifting rods 304 are fixedly installed on the front and rear sides of the top of the activated carbon box 302, and a closing plate 305 is fixedly installed on the top of the activated carbon box 302.

[0040] In use, the lifting rod 304 facilitates the operation of the activated carbon box 302 by the staff when pulling it out and installing it. The closing plate 305 can open the top of the activated carbon box 302, making it convenient for the staff to replace the activated carbon inside.

[0041] like Figure 1 As shown, a support frame 103 is fixedly installed on the outer side of the top of the filter box 1, and a protective canopy 104 is fixedly installed on the top of the support frame 103.

[0042] In use, the support frame 103 can support and install the protective shed 104. The protective shed 104 can protect the top of the device. Protecting the top of the device can inhibit the growth of algae in the wastewater, prevent the grid bar 206 from clogging, stabilize the water temperature, and avoid high temperature accelerating the adsorption saturation of the activated carbon.

[0043] Working principle: The bar screen 206 can filter the wastewater entering the filter box 1. The cleaning rod 209 can lift the foreign objects and garbage filtered down from the bar screen 206. The collection box 4 can collect the garbage lifted by the cleaning rod 209, which is convenient for the staff to centrally process the garbage. The activated carbon box 302 can filter and adsorb wastewater through activated carbon. The mounting bracket 301 can slide the activated carbon box 302, which is convenient for the staff to quickly disassemble, replace and install the activated carbon box 302 later.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
