Description

Technical Field

[0001] The utility model relates to the field of air filtration equipment, in particular to an air filtration device for sewage treatment. Background Art

[0002] In the process of sewage treatment, the main purpose of the air filtration device is to remove impurities, particulate matters or harmful gases in the air to ensure the cleanliness of the treatment environment and the health of the staff. The double-filter cartridge dust collector has significant advantages and applicability in air filtration for sewage treatment. It can not only efficiently remove suspended particles and pollutants in the air, but also adapt to harsh working environments, reducing the maintenance cost and workload.

[0003] In practical applications, the working process of the double-filter cartridge dust collector is to first introduce the air to be treated into the device. Subsequently, the air will pass through a carefully designed filter element for filtration. The filter element can efficiently capture and adsorb suspended particles in the air, and the cleaned air will continue to flow. As time goes by, a certain amount of dust will accumulate on the filter element. At this time, the device will trigger a jitter mechanism through an automatic control system, so that the dust on the filter element is separated and falls into the collection container. However, if the design or assembly of the collection structure is not stable enough and cannot be positioned, dust may leak from the gap during the landing process. This will not only increase the difficulty of dust collection, but also may cause secondary pollution to the working environment. Therefore, an air filtration device for sewage treatment is proposed. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides an air filtration device for sewage treatment. The dust shaken off from the filter cartridge assembly is exported through an export interface, and a collection frame is used for collection. A positioning frame opening is installed at its opening part, which cooperates with a limiting structure. When the air filtration device body is inserted between the air filtration device body and the export interface, the positioning frame opening and the limiting structure are just in a butt-jointed state. In this way, while improving the assembly stability, the connection part is positioned to prevent the problem that the falling dust leaks due to the existence of gaps, avoiding secondary pollution to the working environment, and reducing the collection difficulty.

[0005] In order to solve the above technical problems, the utility model solves the problem that when removing dust, the filter element in the air filtration device for sewage treatment cannot be positioned due to unstable assembly of the collection structure, reducing the collection difficulty.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An air filtration device in sewage treatment, comprising an air filtration device body with a filter cartridge assembly and a dust guide bin.

One end of the opening of the collection frame is provided with a positioning frame opening, and the positioning frame opening and the limiting structure are in a butting state.

[0008] Preferably, clamping blocks are connected to both ends of the limiting structure. A positioning groove is formed at one end of the positioning frame opening facing the limiting structure, and the clamping blocks can be inserted into the positioning groove.

[0009] Preferably, a sealing convex layer is arranged at one end of the limiting structure in contact with the positioning frame opening, and the sealing convex layer and the positioning frame opening are in a state of mutual extrusion.

[0010] Preferably, a plurality of stable bottom pads are evenly distributed at the bottom of the limiting structure, and the stable bottom pads are designed with rubber materials.

[0011] Preferably, the height of the limiting structure is greater than that of the positioning frame opening, and a handle is connected to the outer wall of the collection frame.

[0012] Preferably, an external sleeve is sleeved outside the export interface, and a fixed cylinder part is connected inside the external sleeve through threads. The fixed cylinder part and the limiting structure are connected through a pressure regulating structure.

[0013] Preferably, the pressure regulating structure includes a connecting sleeve plate, a threaded rotating rod and an outer support cylinder. The connecting sleeve plate is fixed at both ends of the chassis of the fixed cylinder part. The threaded rotating rod is movably installed through a bearing inside one connecting sleeve plate. One end of the outer support cylinder is threadedly sleeved outside the threaded rotating rod, and the other end is connected to the top of the limiting structure.

[0014] Preferably, a limiting rod is slidably connected inside the other connecting sleeve plate, and the bottom of the limiting rod is connected to the top of the limiting structure.

[0015] Preferably, a section of thread is arranged on the upper part of the outer wall of the export interface, and the external sleeve is connected thereto.

[0016] Preferably, a top convex ring is glued to the top of the external sleeve, and the top convex ring is in contact with the export interface. A sealing bottom ring is clamped in the groove at the bottom of the external sleeve.

[0017] Compared with the prior art, the present utility model has the following beneficial effects:

[0018] The air filtration device in sewage treatment provided by this application uses an export interface to export the dust shaken off the filter cartridge assembly, and a collection frame is used for collection. A positioning frame opening is installed at its opening part, which cooperates with the limiting structure. When the air filtration device body is inserted between the air filtration device body and the export interface, the positioning frame opening and the limiting structure are just in a butt-jointed state, thereby improving the assembly stability while positioning the connection part, preventing the problem of dust leakage due to gaps during landing, avoiding secondary pollution to the working environment, and reducing the collection difficulty.

[0019] By setting a positioning groove and a clamping block in this application, when the positioning frame opening and the limiting structure are butted, the clamping block is simultaneously driven to be inserted into the positioning groove to position the connection part between the two.

[0020] By setting a sealing convex layer in this application, when the sealing convex layer is installed, the part protruding from the surface of the limiting structure generates an interaction force with the positioning frame opening, so that when the limiting structure presses tightly on the positioning frame opening, the contact surface can be sealed.

[0021] By setting a fixed cylinder part and an external sleeve in this application, the fixed cylinder part can be rotatably installed inside the external sleeve. While connecting to the export interface, it is also convenient to remove the collection frame and perform disassembly operations later, improving applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Please refer toFigure 1 - Figure 8 An air filtration device in sewage treatment, comprising an air filtration device body 1 with a filter cartridge assembly 101 and a dust guide bin 102. The dust guide bin 102 is located below the filter cartridge assembly 101 and is connected to an export interface 2 with a limiting structure 5. The export interface 2 is provided with an opening for collecting with a collection frame member 3. One end of the opening of the collection frame member 3 is provided with a positioning frame opening 4, and the positioning frame opening 4 and the limiting structure 5 are in a butt-jointed state.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The air filtration device in sewage treatment of the present application is mainly composed of structures such as an air filtration device body 1, a filter cartridge assembly 101, and a dust guide bin 102. In application, the dust guide bin 102 is connected with an export interface 2 at its opening for exporting the dust shaken off from the filter cartridge assembly 101. During export, it is collected by a collection frame member 3 inserted into the air filtration device body 1 from below. Among them, a positioning frame opening 4 is fixedly connected to the front part of the opening of the collection frame member 3, and the export interface 2 is provided with a limiting structure 5 for limiting it. When the air filtration device body 1 is inserted between the air filtration device body 1 and the export interface 2, the positioning frame opening 4 and the limiting structure 5 are just in a butt-jointed state. At this time, the positioning frame opening 4 and the limiting structure 5 surround the outside of the export interface 2 and the opening of the collection frame member 3, so as to improve the assembly stability while positioning the connection part, prevent the problem of leakage of the falling dust due to gaps, avoid secondary pollution to the working environment, and also reduce the collection difficulty.

[0038] It should also be noted that both the positioning frame opening 4 and the limiting structure 5 are of arc design, and the height of the limiting structure 5 is greater than that of the positioning frame opening 4, so that when the positioning frame opening 4 is butted against both ends of the limiting structure 5, the contact area between the two can be increased, making the connection more stable.

[0039] In the present application, a positioning groove 401 and a clamping block 501 are also provided. The positioning groove 401 is opened on both sides of the side of the positioning frame opening 4 facing the limiting structure 5, and the clamping block 501 is fixedly installed on both sides of the front end of the limiting structure 5. When the positioning frame opening 4 and the limiting structure 5 are butted, the clamping block 501 is simultaneously driven to be inserted into the inside of the positioning groove 401 to position the connection part between the two.

[0040] In this application, a sealing convex layer 502 is also provided. There are two groups of the sealing convex layer 502, which are respectively located on both sides of the front end of the limiting structure 5 and at the inner ends of the two groups of clamping blocks 501. When installing the sealing convex layer 502, the part protruding from the surface of the limiting structure 5 generates an interaction force with the positioning frame opening 4, so that when the limiting structure 5 is tightly pressed on the positioning frame opening 4, the contact surface can be sealed.

[0041] In this application, a stable bottom pad 503 is also provided. The stable bottom pad 503 is evenly glued to the bottom of the limiting structure 5. After adjusting the height of the limiting structure 5, the limiting structure 5 can tightly press the whole collecting frame member 3 onto the air filtering device body 1, so as to further improve the stability of the collecting frame member 3 after assembly. During long-term application, the pressing operation can be adjusted. When pressing, it drives the sealing convex layer 502 to contact the surface of the outlet interface 2, so as to further increase the friction force of the contact surface and make the fixation more stable.

[0042] In this application, a fixing cylinder member 6 and an external sleeve 7 are also provided. The external sleeve 7 cooperates with the outlet interface 2 to make the fixing cylinder member 6 be rotationally connected thereto by threads. The fixing cylinder member 6 and the limiting structure 5 are connected through a pressure regulating structure, so as to support the overall structure of the limiting structure 5. At the same time, the fixing cylinder member 6 is rotatably installed inside the external sleeve 7. When connected to the outlet interface 2, it is also convenient to disassemble the collecting frame member 3 after taking it out later, improving the applicability; the handle 301 is fixed on the outer wall of the collecting frame member 3, which is convenient for the forward extraction action.

[0043] It should also be noted that a section of thread is provided on the upper part of the outer wall of the outlet interface 2. The design of this thread matches the internal thread of the external sleeve 7, so that it can be sleeved outside the outlet interface 2 from bottom to top and then rotated to thread-connect the two, which is convenient for assembly and can also be relocated according to the use requirements.

[0044] In this application, a pressure regulating structure is also provided. The pressure regulating structure is mainly composed of a connecting sleeve plate 601, a threaded rotating rod 602 and an outer support cylinder 603. The connecting sleeve plate 601 is fixedly installed on both sides of the bottom plate of the fixing cylinder member 6, so that the threaded rotating rod 602 is vertically movably installed inside the connecting sleeve plate 601 on one side through a bearing, and the end extending to the bottom is thread-connected to the outer support cylinder 603. The outer support cylinder 603 and the limiting structure 5 are of an integral structure design. By rotating the handle of the threaded rotating rod 602, the outer support cylinder 603 can drive the limiting structure 5 to move up and down, so as to adjust the height between the limiting structure 5 and the collecting frame member 3 for pressing operation.

[0045] In this application, a limiting rod 604 is also provided. The limiting rod 604 is fixedly installed on the upper surface of the limiting structure 5, allowing the connecting sleeve plate 601 on the other side to slide thereon. When the outer support cylinder 603 moves up and down, the limiting rod 604 is driven to move in the same direction, ensuring stability while also performing a limiting operation on it.

[0046] In this application, a top convex ring 701 and a sealing bottom ring 702 are also provided. The top convex ring 701 is adhesively bonded to the top of the external connection sleeve 7. When the external connection sleeve 7 is rotatably connected to the outside of the export interface 2, the sealing bottom ring 702 at its top can contact the connection disk on the export interface 2 to improve the stability after connection; the sealing bottom ring 702 is snap-fitted into the groove opened at the bottom plate of the external connection sleeve 7. Therefore, when the fixed cylinder member 6 is rotated and connected to the external connection sleeve 7, the sealing bottom ring 702 can be located at the connection between the two, thereby improving the tightness of the connection.
