Description

Technical Field

[0001] The utility model mainly relates to the technical field of air filtering equipment, in particular to an air filter. Background Art

[0002] Air filters are devices used for air filtration and purification. They are generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. Especially in the textile manufacturing industry, air filters are usually purchased for filtering and purifying air.

[0003] Air filters have been widely used. At present, air filters are generally installed on the walls of textile manufacturing workshops to filter and purify the air. For example, an intermittent blowing and suction disc filter disclosed in the application case of Chinese patent application No. 201020631415.6 uses a rotary single-arm suction nozzle to vacuum the fiber dust on the filter mesh surface. Although this filter can vacuum the filter mesh surface, for filters with square filter mesh surfaces, the rotary single-arm suction nozzle cannot effectively vacuum all positions of the filter mesh surface, and its dust suction effect is relatively limited. There are limitations to its use. In addition, due to the relatively large volume of the single-arm suction nozzle, the rotating single-arm suction nozzle will also have a greater impact on the return air volume of the workshop. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0027] See attached Figure 1-3 An air filter of this embodiment includes a mounting frame 1, in which a square filter screen 2 is mounted, and the size of the filter screen 2 matches the size of the mounting frame 1. A rack 9 that can be driven to move up and down is mounted on the inner side of the filter screen 2 in the mounting frame 1, and a suction nozzle 5 that can be driven to move laterally is mounted on the rack 9, and the suction port of the suction nozzle 5 is close to the filter screen 2. The suction nozzle 5 is connected to an external dust collecting fan 3, and dust is sucked from various positions of the filter screen 2 by the moving suction nozzle 5.

[0028] Specifically, vertical grooves are correspondingly provided on both side walls of the inner side of the filter screen surface 2 in the installation frame 1, wherein a guide rod 8 is correspondingly installed in one groove, and a threaded screw 7 that can be driven to rotate is correspondingly installed in the other groove. A first motor 6 is installed at a corresponding position on one side of the top of the installation frame 1, and the output shaft of the first motor 6 is correspondingly connected to the top of the threaded screw 7 by transmission, and the threaded screw 7 is driven to rotate by the first motor 6. A through guide hole 902 is correspondingly provided at one end of the rack 9, and the guide hole 902 at one end of the rack 9 is correspondingly slidably mounted on the guide rod 8, and the sliding cooperation between the guide rod 8 and the guide hole 902 makes the lifting and lowering movement of the rack 9 more stable and reliable. A through threaded hole 901 is correspondingly provided at the other end of the rack 9, and the threaded hole 901 at the other end of the rack 9 is correspondingly threadedly installed on the threaded screw 7, and the rack 9 is lifted and lowered by rotating the threaded screw 7. It is worth noting that the threaded hole 901 can also be replaced by an existing threaded sleeve, that is, a threaded sleeve is correspondingly provided at the other end of the rack 9, and the threaded sleeve is correspondingly installed on the threaded screw 7, and the rack 9 is raised and lowered by rotating the threaded screw 7.

[0029] The length of the rack 9 corresponds to the length of the filter screen 2. A U-shaped frame 12 is correspondingly installed on the rack 9, and the rack 9 is correspondingly installed between the upper and lower sides of the U-shaped frame 12. A strip-shaped slide 903 is correspondingly provided on the top of the rack 9, and a slider 1201 is correspondingly provided on the inner top of the U-shaped frame 12, and the slider 1201 is correspondingly slidably installed in the slide 903.

A gear 10 that can be driven to rotate is correspondingly installed on the inner side of the U-shaped frame 12, and the gear 10 is correspondingly meshed and connected with the rack 9. A second motor 10 is installed at the corresponding position on the top of the U-shaped frame 12, and the output shaft of the second motor 10 passes through the upper side plate of the U-shaped frame 12. The gear 10 is correspondingly installed on the output shaft of the second motor 10, and the gear 10 is driven to rotate by the second motor 10, so that the U-shaped frame 12 moves horizontally on the rack 9.

[0030] A connecting hose 4 is correspondingly installed at the bottom of the suction nozzle 5, one end of the connecting hose 4 is correspondingly connected to the suction nozzle 5, and the other end of the connecting hose 4 passes through the bottom of the mounting frame 1 and is correspondingly connected to the suction end of the dust collecting fan 7. The air outlet end of the dust collecting fan 3 can be connected to the dust collecting bag through a pipeline. The suction nozzle 5 can adopt a hood-type structure, and one side of its hood opening corresponds to the filter screen surface 2. It is worth noting that a certain length margin can be left for the connecting hose 4 in the mounting frame 1 so that the suction nozzle 5 can be smoothly moved to various positions of the filter screen surface 2 for dust collection.

[0031] It is worth noting that the air filter is installed on the wall for use, and the size of the installation frame 1 can be adapted to the size of the preset installation hole on the wall; the first motor 6 can also be installed in the wall accordingly. The model and size of the dust collecting fan 3 can be selected according to the actual installation and use. During operation, the second motor 10 drives the gear 11 to rotate, so that the suction nozzle 5 moves horizontally, and the same height position on the filter screen 2 is sucked in sequence; when the suction nozzle 5 moves horizontally to the end of one side of the rack 9, the first motor 5 drives the threaded screw 7 to rotate a certain number of circles, so that the rack 9 rises or falls a certain height, and controls the second motor 10 to reverse, so that another height position on the filter screen 2 is sucked in sequence; the operation is carried out sequentially, when the rack 9 moves from the top of the filter screen 2 to the bottom of the filter screen 2 in sequence, the filter screen 2 is sucked at each position, and the first motor 5 can be controlled to reverse, so as to continuously reciprocate the filter screen 2. It is worth noting that the threaded screw 7 may also adopt an existing reciprocating screw, so that the rack 9 can be moved up and down reciprocatingly even when the first motor 6 does not reverse.
