Description

Technical Field

[0001] The utility model belongs to the technical field of air filtering equipment, and in particular relates to a liquid tank type air filter which is easy to repair. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the low-dust air into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] Since the liquid tank type air filter is embedded in the wall, during maintenance, the conventional liquid tank type air filter lacks a gripping point, and it is difficult to exert force to pull out the liquid tank type air filter, which causes the problem that it is difficult to pull out the conventional liquid tank type air filter for maintenance.

[0004] For this reason, we propose a liquid tank type air filter which is easy to maintain to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that it is difficult to extract and overhaul a conventional liquid tank type air filter, and proposes a liquid tank type air filter which is easy to overhaul.

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

[0007] A liquid tank type air filter that is easy to repair includes a filter body, a connection frame is provided at the outer end of the filter body, bolts are inserted into the connection frame, the bolts are threadedly connected to the filter body, a handle is rotatably connected to the connection frame, and the handle is snap-fitted with the connection frame. The connection frame is fixedly installed on the filter body by bolts, and after installation, the handle is put into the connection frame, and when taking it out, the handle is unfolded, and then the handle is pulled outward by hand to make the filter body detach from the installation slot. Compared with traditional liquid tank type air filters, it is convenient to pull out the filter for repair.

[0008] Preferably, the filter body includes a housing and a filter core, the housing is provided with a threaded hole, and the filter core is fixedly connected to the inner end of the housing. The bolts are passed through the connection frame, and then screwed into the threaded holes with the help of a screwdriver, and the connection frame is pressed and fixed to the outside of the housing with the bolts, so as to facilitate the assembly of the filter body and the connection frame.

[0009] Preferably, the filter body further comprises a protective net, which is fixedly connected to the inner end of the housing. The protective net is used to block the outer end of the filter element to facilitate the protection of the filter element.

[0010] Preferably, the connection frame includes a frame body, and a receiving groove is provided on the frame body. After the handle is folded, the handle is inserted into the receiving groove, and the receiving groove is used to receive the handle, so that the outer frame of the filter can be installed normally, which is convenient for reducing the space occupied by the connection frame and the handle after installation.

[0011] Preferably, the upper symmetrical hollow of the frame body is provided with a mounting hole, and a bolt is passed through the mounting hole and then tightened so that the bolt knob enters the mounting hole to prevent the bolt knob from protruding outward.

[0012] Preferably, the handle includes a grip and a shaft, and the shaft is fixedly connected to the grip. The grip is unfolded outward, and then the grip is pulled outward by hand, so that the grip acts on the connection frame, and the connection frame acts on the filter body, so that the filter body is separated from the target slot, which is convenient for hand-held operation.

[0013] Preferably, the handle further comprises an elastic sheet, which is movably engaged with the grip, and one end of the elastic sheet is fixedly connected to the grip. When the outer end of the grip loses pressure, the elastic force of the rotating shaft acts on the grip, so that the grip automatically pops out of the oil receiving groove. After the grip is folded, the grip is pressed into the receiving groove by the pressure of the filter outer frame, so that the handle automatically pops out.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Use bolts to fix the connection frame on the filter body. After installation, put the handle into the connection frame. When taking it out, unfold the handle and then pull it outward to separate the filter body from the installation slot. Compared with the traditional liquid tank air filter, it is convenient to pull out the filter for maintenance.

[0016] 2. Pass the bolts through the connection frame, and then use a screwdriver to screw the bolts into the threaded holes. Use the bolts to press and fix the connection frame to the outside of the shell to facilitate the assembly of the filter body and the connection frame.

[0017] 3. After the handle is folded up, the handle is inserted into the receiving groove, and the receiving groove is used to accommodate the handle so that the outer frame of the filter can be installed normally, which is convenient for reducing the space occupied by the connection frame and the handle after installation.

[0018] 4. Expand the handle outward, then pull the handle outward, act on the connection frame through the handle, and act on the filter body through the connection frame, so that the filter body is separated from the target slot, which is convenient for hand-held operation.

[0019] 5. When the outer end of the grip loses pressure, the elastic force of the shaft acts on the grip, causing the grip to automatically pop out of the oil receiving tank. After the grip is put away, the pressure of the filter outer frame is used to press the grip into the receiving tank, making it easy for the handle to pop out automatically.
