Description

Technical Field

[0001] This application relates to the technical field of filters, and in particular to a filter with a dual-layer filtration structure. Background Technology

[0002] Bag filters, as a common fluid filtration device, are widely used in water treatment, chemical, food and other industries to remove suspended particles and impurities from liquids. They are small in size, easy and flexible to operate, energy-saving, efficient, sealed, and versatile. Bag filters are a new type of filtration system. Inside the bag filter, a metal mesh basket supports the filter bag. Liquid flows in through the inlet, is filtered by the filter bag, and flows out through the outlet. Impurities are trapped in the filter bag, and the filter can be reused after the filter bag is replaced.

[0003] Traditional bag filters mostly use a single-layer filter screen or filter bag structure, which has problems such as limited filtration area, easy clogging, and inconvenient sewage discharge. Especially when treating sewage with a large amount of impurities, frequent shutdowns for cleaning are required, which affects filtration efficiency and equipment continuity.

[0004] Therefore, those skilled in the art have provided a filter with a dual-layer filtration structure to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a filter with a dual-layer filtration structure.

[0006] The filter with a dual-layer filtration structure provided in this application adopts the following technical solution:

[0007] A filter with a double-layer filtration structure includes a bag filter body, an installation frame fixed to the upper end of the bag filter body, a filter plate fixed to the inner side of the installation frame, through holes evenly opened at both ends of the filter plate, a plate fixed to the upper end of the installation frame, a pipe body centrally connected to the upper end of the plate, and sewage discharge components symmetrically installed at the front and rear ends of the installation frame.

[0008] Preferably, the sewage discharge assembly includes a housing, which is fixedly connected to the mounting frame. A gear is rotatably connected to the inner side of the housing, and two parallel and staggered racks are meshed to the outer side of the gear. A connecting plate is fixedly connected to the end of each rack, and a plug is fixedly connected to the end of the connecting plate, which passes through the sewage discharge port on the side wall of the mounting frame. A threaded rod is threadedly connected to the end of one of the racks, and a self-locking motor is installed at the end of the threaded rod.

[0009] Preferably, the filter plate has a V-shaped design, with the filter plate tilted downwards towards both the front and rear ends.

[0010] Preferably, a protective cover is installed at the center of the upper end of the filter plate. The protective cover has a conical design and is directly opposite the bottom end of the tube.

[0011] Preferably, a rubber layer is fixed to the outer side of the plug, and a limit ring is fixed to the outer side of the plug and the end near the connecting plate.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By adopting a V-shaped filter plate and evenly arranged through holes, a double-layer filtration structure is formed, which significantly increases the effective filtration area, improves the impurity interception capacity and filtration efficiency, and the inclined structure facilitates the automatic collection of dirt and guides it to the drain outlet, effectively reducing filter plate clogging and extending the cleaning cycle. The conical protective cover set above the filter plate can disperse the impact of incoming water, prevent the fluid from directly washing the filter plate, protect the filtration structure, and improve the service life of the equipment.

[0014] 2. By setting up a sewage discharge assembly consisting of a self-locking motor, gears, racks and pinions, the automatic, synchronous, bidirectional opening and closing operation of the sewage discharge port is realized. This not only improves the automation level of the equipment and reduces the intensity of manual operation, but also enhances the sealing performance of the sewage discharge port in the closed state through the cooperation of the rubber layer and the limit ring, effectively preventing sewage leakage.

[0019] 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.

[0020] Example 1

[0021] like Figure 1-2As shown, this application discloses a filter with a double-layer filtration structure, including a bag filter body 1, an installation frame 2 fixedly connected to the upper end of the bag filter body 1, a filter plate 5 installed on the inner side of the installation frame 2, through holes 6 evenly opened at the upper and lower ends of the filter plate 5, a plate 3 installed at the upper end of the installation frame 2, a pipe body 4 installed in the center of the upper end of the plate 3, and sewage discharge components symmetrically installed at the front and rear ends of the installation frame 2.

[0022] Wastewater enters the mounting frame 2 through the pipe 4 on the plate 3 and is filtered through the through holes 6 on the filter plate 5. The filtered dirt moves along the inclined wall of the filter plate 5 to the drain port on the mounting frame 2. The drain port on the mounting frame 2 is opened and closed by operating the drain assembly. The wastewater filtered by the filter plate 5 is then filtered through the bag filter body 1.

[0023] like Figure 1-3 As shown, the sewage discharge assembly includes a housing 8, which is fixedly connected to the mounting frame 2. A gear 9 is rotatably connected to the inner side of the housing 8. Two parallel and staggered racks 10 are meshed with the outer side of the gear 9. A connecting plate 11 is fixedly connected to the end of each rack 10. A plug 12 is fixedly connected to the end of the connecting plate 11, penetrating the sewage discharge port on the side wall of the mounting frame 2. A threaded rod 15 is threadedly connected to the end of one rack 10. A self-locking motor 16 is installed at the end of the threaded rod 15. The self-locking motor 16 drives the threaded rod 15 to rotate. The threaded rod 15 drives one rack 10 to move. The other rack 10 moves relative to it through the gear 9. Thus, the plug 12 is driven by the connecting plate 11 to be inserted into or pulled out of the sewage discharge port on the mounting frame 2.

[0024] like Figure 3 As shown, a rubber layer 13 is fixed to the outside of the plug body 12, and a limiting ring 14 is fixed to the outside of the plug body 12 and the end near the connecting plate 11. By setting the rubber layer 13, the sealing between the plug body 12 and the mounting frame 2 can be improved, and the limiting ring 14 can limit the plug body 12.

[0025] like Figure 2 As shown, the filter plate 5 has a V-shaped design and is inclined downwards towards the front and rear ends. By setting the V-shaped filter plate 5, the filtered material can be guided to move towards the front and rear ends of the mounting frame 2.

[0026] like Figure 2 As shown, a protective cover 7 is installed in the center of the upper end of the filter plate 5. The protective cover 7 is a conical design and is directly opposite the bottom end of the tube body 4. By setting the protective cover 7 directly opposite the bottom end of the tube body 4, the liquid entering the tube body 4 can be prevented from directly impacting the filter plate 5.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The implementation principle of a filter with a dual-layer filtration structure in this application embodiment is as follows:

[0030] In use, sewage first enters the mounting frame 2 through the top pipe 4. The filter plate 5 has a V-shaped design, and the uniformly opened through holes 6 on its surface form a double-layer filtration structure, which can effectively filter sewage. Impurities are trapped on the surface of the filter plate 5. Since the filter plate 5 has an inclined structure, the filtered dirt moves along the inclined wall to the sewage outlets on both sides of the mounting frame 2 under the action of gravity. When sewage needs to be discharged, the self-locking motor 16 starts, drives the threaded rod 15 to rotate, and drives the meshing rack 10 to move horizontally. Through the transmission of the gear 9, the two symmetrically arranged racks 10 achieve synchronous reverse movement, which in turn drives the connecting plate 11 and the plug 12 to insert or withdraw from the sewage outlet, realizing the opening and closing of the sewage outlet. The rubber layer 13 on the outside of the plug 12 enhances the sealing effect, and the limiting ring 14 limits the movement position of the plug 12 to ensure accurate and reliable operation. The filtered sewage is then treated through the bag filter body 1.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
