Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment filter. Background Technology

[0002] Wastewater filters are key equipment used to remove pollutants such as suspended solids, particulate matter, colloids, and microorganisms from water. They are widely used in municipal sewage, industrial wastewater, and decentralized rural sewage treatment scenarios to improve water quality and meet discharge standards.

[0003] Traditional wastewater treatment filters often use fixed filter screens or filter media layers. Pollutants easily accumulate on the surface of the filter screen, causing blockages and reducing filtration efficiency. It is necessary to clean the impurities on the top of the filter screen regularly to improve the filtration efficiency. Therefore, it is necessary to shut down the machine periodically to clean the impurities on the top of the filter screen. However, cleaning the impurities on the top of the filter screen takes a lot of time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment filter that solves the problem that existing wastewater filters are not easy to clean the impurities on the top of their filter screens.

A pushing component is also provided inside the housing to push impurities on the top of the filter screen from the feed inlet into the impurity recovery frame.

[0006] Compared with the prior art, this utility model has the following advantages: by setting a groove on the top of the filter screen and placing an impurity collection frame in the groove, the pushing component periodically pushes the impurities on the top of the filter screen into the impurity collection frame. When the impurities in the impurity collection frame accumulate to a certain extent, the impurity collection frame is removed from the opening at the top of the box, thus cleaning the impurities on the top of the filter screen. This avoids excessive accumulation of impurities on the top of the filter screen, which would affect its permeability. At the same time, it eliminates the need to shut down the sewage treatment filter, thereby improving the sewage treatment efficiency.

[0007] Furthermore, the pushing component includes: a motor, a lead screw, a guide rod, and a pushing plate. The motor is fixed to the side wall of the housing, and the guide rod and lead screw are both horizontally arranged inside the housing.

The pushing plate is slidably connected to the guide rod in the horizontal direction, the pushing plate is threadedly connected to the lead screw, and the pushing plate is slidably connected to the top of the filter screen.

[0008] Furthermore, several rubber heads are provided at the bottom of the push plate.

[0009] Furthermore, it also includes a plug-in plate, which is used to open and close the feed inlet. The side wall of the impurity recovery frame is provided with at least one mounting groove, and each mounting groove is provided with a locking mechanism. The side wall of the plug-in plate is provided with a locking groove that matches the locking mechanism.

[0010] Furthermore, each of the aforementioned locking mechanisms includes a locking pin, a pull rod, and a spring. The locking pin and the spring are both disposed in the mounting groove.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown in the figure, this utility model embodiment proposes a sewage treatment filter, including: a housing 1, a filter screen 2, and an impurity recovery frame 3. The top of the housing 1 is open, the filter screen 2 is horizontally fixed inside the housing 1, a drain outlet 5 is provided on one side of the bottom of the housing 1, a groove for placing the impurity recovery frame 3 is provided on one side of the top of the filter screen 2, a water filter mesh 4 is provided at the bottom of the impurity recovery frame 3, and a feed inlet is provided on one side of the impurity recovery frame 3. The bottom of the feed inlet is on the same horizontal plane as the top of the filter screen 2. A pushing component is also provided inside the housing 1, which is used to push the impurities on the top of the filter screen 2 from the feed inlet into the impurity recovery frame 3.

[0019] By setting a groove on the top of the filter screen 2 and placing the impurity collection frame 3 in the groove, the pushing component periodically pushes the impurities on the top of the filter screen 2 into the impurity collection frame 3. When the impurities in the impurity collection frame 3 accumulate to a certain extent, the impurity collection frame 3 is removed from the opening at the top of the box 1. This allows the impurities on the top of the filter screen 2 to be cleaned, preventing excessive accumulation of impurities on the top of the filter screen 2 from affecting its permeability. At the same time, there is no need to turn off the sewage treatment filter, thus improving the sewage treatment efficiency.

[0020] Furthermore, such as Figure 1 As shown, the pushing assembly includes: a motor 6, a lead screw 7, a guide rod 8, and a pushing plate 9. The motor 6 is fixed to the side wall of the housing 1. The guide rod 8 and the lead screw 7 are both horizontally arranged inside the housing 1. The output end of the motor 6 is connected to the lead screw 7. The motor 6 is used to drive the lead screw 7 to rotate. The pushing plate 9 is slidably connected to the guide rod 8 in the horizontal direction. The pushing plate 9 is threadedly connected to the lead screw 7. The pushing plate 9 is slidably connected to the top of the filter screen 2.

[0021] Specifically, the motor 6 drives the lead screw 7 to rotate, and the lead screw 7 drives the pusher plate 9 to move towards the impurity recovery frame 3. During the movement, the pusher plate 9 pushes the impurities on the top of the filter screen 2 towards the impurity recovery frame 3. Finally, the impurities enter the impurity recovery frame 3 from the feed inlet on the side wall of the impurity recovery frame 3. At the same time, several rubber heads 10 can be set at the bottom of the pusher plate 9 to reduce the wear of the pusher plate 9 on the filter screen 2. It is worth noting that since the pusher plate 9 has a certain thickness, a part of the pusher plate 9 can be inserted into the impurity recovery frame 3 from the feed inlet, and the pusher plate 9 will not detach from the lead screw 7.

[0022] Furthermore, such as Figure 1 and Figure 2As shown, it also includes a plug-in plate 11, which is used to open and close the feed port. The side wall of the impurity recovery frame 3 is provided with at least one mounting groove 12, and each mounting groove 12 is provided with a locking mechanism. The side wall of the plug-in plate 11 is provided with a locking groove 13 that matches the locking mechanism.

[0023] like Figure 2 As shown, each of the locking mechanisms includes a locking pin 14, a pull rod 16, and a spring 15. The locking pin 14 and the spring 15 are both disposed in the mounting groove 12. The locking pin 14 is slidably connected to the mounting groove 12. One end of the pull rod 16 is fixed to the end of the locking pin 14, and the other end of the pull rod 16 extends out of the impurity collection frame 3. The pull rod 16 is slidably connected to the impurity collection frame 3. When the locking pin 14 is aligned with the locking groove 13, the locking pin 14 is inserted into the locking groove 13 under the elastic force of the spring 15. The top of the end of each locking pin 14 extending out of the mounting groove 12 is an inclined slope.

[0024] Specifically, by setting a plug-in plate 11, a connecting post 17 is fixedly installed on the top of the plug-in plate 11. The connecting post 17 extends out of the housing 1, and a handle 18 is provided on the side wall of the connecting post 17. By holding the handle 18, the connecting post 17 and the plug-in plate 11 are aligned vertically with the feed inlet of the impurity recovery frame 3. Then, the connecting post 17 is pushed vertically to make the plug-in plate 11 vertically inserted into the feed inlet. When the plug-in plate 11 contacts the inclined surface at the top of the locking pin 14, the plug-in plate 11 pushes the locking pin 14, and the locking pin 14... The locking pin 14 moves towards the mounting slot 12 so that it does not obstruct the vertical downward movement of the plug plate 11. When the locking pin 14 is aligned with the locking slot 13, the locking pin 14 is inserted into the locking slot 13 under the elastic force of the spring 15, thereby fixing the plug plate 11. This makes it easy to remove the entire impurity collection frame 3 by pulling the handle 18, which is convenient for workers to clean impurities. When it is necessary to remove the plug plate 11, simply pull the lever 16 to disengage the locking pin 14 from the locking slot 13.

[0025] Furthermore, an activated carbon filter layer 19 is provided inside the housing 1, which is located below the filter screen 2; a mounting frame 20 is also provided on the top of the housing 1, and a water inlet hopper 21 is fixedly installed on the mounting frame 20.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
