Description

Technical Field

[0001] This utility model belongs to the technical field of municipal sewage treatment, and in particular relates to a filtration device for municipal sewage treatment. Background Technology

[0002] Municipal wastewater treatment equipment is mainly used to treat various types of wastewater from urban life, including laundry wastewater, rice washing wastewater, toilet flushing wastewater, and other domestic water. The wastewater treatment technologies used in these devices effectively remove harmful substances from the wastewater, ensuring that the water quality meets discharge standards. The most crucial step in municipal wastewater treatment is filtration, which can remove a large amount of impurities. However, in actual filtration processes, the following drawbacks still exist:

[0003] First, as in the utility model with application number 202122797822.5, this type of filtration device uses a closed treatment tank for filtration. However, there are a lot of solid impurities in the sewage. Filtration is to filter out a lot of solid impurities, so a lot of solid impurities will inevitably accumulate during filtration. The closed treatment tank will inevitably affect the cleaning and discharge of impurities. It is easy to cause blockage and garbage accumulation after filtration for a period of time, which is inconvenient to clean and brings great trouble to the filtration operation.

[0004] Secondly, regardless of whether a filter screen or a filter grid is used for filtration, it will inevitably need to be replaced after a period of use. However, fixed filter structures are difficult to disassemble and replace, which increases costs.

[0005] Finally, municipal wastewater comes in many forms, but after being stored for a long time, it will develop some odor, and it usually cannot be filtered in one go and needs to be filtered multiple times before proceeding to the next process. Utility Model Content

[0006] The purpose of this utility model is to provide a filtration device for municipal sewage treatment. By setting up a filter box, filter frame, filter grid, guide plate, rotating shaft, strip plate, filter basket, and activated carbon block, it solves the problems of large amount of impurities filtered out after sewage filtration being inconvenient to clean, filter structure being inconvenient to replace, single filtration not meeting treatment needs, and a large amount of odor.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a filtration device for municipal sewage treatment, including a filter box, filter frames, a guide plate, a strip plate, and a rod. The filter box contains three filter frames arranged side by side. A filter grid is fixed inside the filter frame. A filter basket is fixed to the bottom surface of the filter frame, and activated carbon blocks are placed inside the filter basket. A rotating shaft is fixed to both sides of the filter frame. A guide plate is rotatably connected to the filter box below the filter frame. A rotating shaft is fixed to both sides of the guide plate, and the rotating shaft is rotatably connected to the side wall of the filter box.

[0009] Furthermore, slots are provided at equal intervals on both inner walls of the filter box, and the rotating shafts on both sides of the filter frame are respectively inserted into the slots on the two inner walls of the filter box.

[0010] Furthermore, strips are provided on the outer side walls of both sides of the filter box. A handle is fixed on the side of the strip away from the filter box, and equally spaced insertion posts are fixed on the side of the strip close to the filter box. The insertion posts penetrate the filter box and are inserted into a limiting hole opened on the side of the filter frame.

[0011] Furthermore, a through insertion hole is provided on the side wall of the filter box below the strip plate, and the guide plate is inclined. Two limiting holes are provided on both sides of the guide plate. Insert rods are inserted into the two insertion holes that are coaxial with the limiting holes, and the insertion rods pass through the insertion holes and are inserted into the limiting holes. A wristband is fixed on the side of the insertion rod away from the guide plate.

[0012] Furthermore, a slag discharge port is provided at one end of the filter box, and a drain port is provided at the other end of the filter box. The drain port and the slag discharge port are of equal size and are arranged opposite to each other.

[0013] Furthermore, the two ends of the guide plate are located inside the slag discharge port and the drain port, and a drainage channel is fixed on the outer end wall of the filter box outside the drain port.

[0014] This utility model has the following beneficial effects:

[0015] This utility model solves the problem of inconvenient cleaning of large amounts of impurities filtered out after sewage filtration by setting up a filter box, filter frame, filter grid, and guide plate; it uses the filter box as the main filtration site, in conjunction with the filter frame and its internal filter grid to filter sewage, and then the filtered sewage is discharged along the guide plate towards the drain outlet and drainage channel (e.g., Figure 1 , 2 (State), the filtered impurities remain on the filter grid. When cleaning is required, flip the guide plate so that its bottom end faces the slag discharge port (e.g., ...). Figure 3 (In the current state), pull out the strip plate and flip the filter frame so that the surface of the filter grid faces down. At this time, a large amount of impurities fall off and are discharged along the guide plate towards the slag discharge port, achieving rapid slag discharge and saving cleaning steps.

[0016] This utility model solves the problem of inconvenient filter structure replacement by setting up a filter box, filter frame, rotating shaft, and strip plate. The filter frame is inserted into the slot in the filter box through the rotating shaft, and then the insert on the side of the strip plate is inserted into the side of the filter frame to keep the filter frame in a horizontal and constant position, which facilitates filtration. When replacing the filter frame, the strip plate is pulled out and the filter frame is taken out for replacement, which is simple and convenient.

[0017] This utility model solves the problem that single filtration cannot meet the treatment needs and produces a lot of odor by setting up a filter box, filter frame, filter grid, filter basket and activated carbon block. First, the filter grid in the filter frame is used for initial filtration, then the activated carbon block is used for odor removal, and finally the filter basket is used for secondary filtration, thus achieving dual filtration and a certain degree of odor removal.

A filter basket 202 is fixed to the bottom surface of the filter frame 2, and an activated carbon block 205 is arranged inside the filter basket 202. A rotating shaft 203 is fixed to both sides of the filter frame 2. A guide plate 3 is rotatably connected to the filter box 1 below the filter frame 2. A rotating shaft 301 is fixed to both sides of the guide plate 3, and the rotating shaft 301 is rotatably connected to the side wall of the filter box 1.

[0030] The filter box 1 serves as the main filtration site, and its interior is equipped with three filter frames 2 as the main filtration structure. The filter frames 2 are equipped with filter grids 201 for primary filtration, then activated carbon blocks 205 for deodorization, and finally filter baskets 202 for secondary filtration, achieving dual filtration and a certain degree of deodorization. The filter frames 2 are inserted into the slots 101 inside the filter box 1 via a rotating shaft 203. The filtered wastewater is guided from the guide plate 3 to the drain outlet 105 and the drain channel 103. The guide plate 3 can be rotated to a certain extent via a rotating shaft 301 to adjust the direction of material feeding.

[0031] The filter box 1 has slots 101 that are evenly distributed on both inner walls, and the rotating shafts 203 on both sides of the filter frame 2 are respectively inserted into the slots 101 on the two inner walls of the filter box 1.

[0032] Slot 101 is used to define the installation space for the rotating shaft 203, and the filter frame 2 can be flipped around the rotating shaft 203 within slot 101.

[0033] The filter box 1 is also provided with strips 4 on both sides of the outer side. A handle 401 is fixed on the side of the strip 4 away from the filter box 1. Equally spaced insertion posts 402 are fixed on the side of the strip 4 close to the filter box 1. The insertion posts 402 penetrate the filter box 1 and are inserted into the limiting hole 204 opened on the side of the filter frame 2.

[0034] Insert the insert post 402 on the side of the strip 4 through the filter box 1 and into the limiting hole 204 to provide horizontal and stable support for the filter frame 2, so that the filter frame 2 is horizontal and no other fasteners are needed to fix it.

[0035] A through insertion hole 104 is provided on the side wall of the filter box 1 below the strip plate 4, and the guide plate 3 is inclined. Two limiting holes 302 are provided on both sides of the guide plate 3. Insert rods 5 are inserted into the two insertion holes 104 that are coaxial with the limiting holes 302. The insertion rods 5 pass through the insertion holes 104 and are inserted into the limiting holes 302. A wristband 501 is fixed on the side of the insertion rods 5 away from the guide plate 3.

[0036] After flipping the guide plate 3 to the desired angle, hold the wristband 501 and insert the rod 5 through the insertion hole 104 into the limiting hole 302 to limit the position of the guide plate 3 and prevent it from shaking.

[0037] The filter box 1 has a slag discharge port 102 at one end and a drain port 105 at the other end. The drain port 105 and the slag discharge port 102 are of equal size and are arranged opposite to each other.

[0039] The specific working principle of this utility model is as follows: First, after flipping the guide plate 3 to the required angle, hold the wristband 501 and insert the insertion rod 5 through the insertion hole 104 into the limiting hole 302 to limit the position of the guide plate 3. Figure 1 , 2 As shown in the diagram, filter frame 2 is then inserted into slot 101 in filter box 1 via pivot 203. Then, insert post 402 on the side of strip 4 through filter box 1 into limiting hole 204 to provide horizontal and stable support for filter frame 2, thus making filter frame 2 horizontal. At this time, sewage filtration can be performed. Filter grid 201 is set in filter frame 2 for primary filtration, followed by odor removal using activated carbon block 205, and finally secondary filtration using filter basket 202. The sewage is discharged along guide plate 3 towards drain outlet 105 and drain channel 103, and the filtered impurities remain on filter grid 201.

[0040] Then, pull out the insert rod 5 and flip the guide plate 3 to the position shown. Figure 3 In the state shown, insert the rod 5 into the position of the limiting guide plate 3, pull out the strip plate 4, flip the filter frame 2 so that the surface of the filter grid 201 is facing down. At this time, a large amount of impurities fall off and are discharged along the guide plate 3 towards the slag discharge port 102, thus achieving rapid slag discharge.

[0041] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
