Description

Technical Field

[0001] The utility model relates to the field of production equipment, in particular to a multi-filter dust removal device. Background Art

[0002] In workplaces for cleaning, grinding, sorting, and inspecting paper printed products, a large amount of dust and particulate matter are usually generated. If not filtered in time, it is easy to affect the quality of the production environment. The traditional filter dust removal device is provided with air inlet mesh holes on the workbench surface. The air inlet mesh holes are connected to the air inlet of an outdoor exhaust fan through a pipeline, and the air outlet of the exhaust fan is then connected to a filter device for collecting dust and particulate matter. Usually, only a single filter screen is used for filtration during filtration, resulting in a poor filtration effect of the filter device. Therefore, improvement is still needed. Summary of the Utility Model

[0003] To solve the problems mentioned above, the utility model provides a multi-filter dust removal device, which includes an air inlet, a filter box, and a fan. A grille is arranged at the lower end position inside the air inlet. The lower end of the air inlet is connected with an air supply pipe, and the end of the air supply pipe is connected with a filter box. A plurality of rectangular notches are formed on the left and right side walls of the filter box. A sliding groove is arranged inside the rectangular notch, and a limiting plate is arranged at the end of the sliding groove. A first filter device and a second filter device are inserted into the rectangular notch in a reverse symmetric and staggered manner. The rear end of the filter box is connected with a fan, and the rear end of the fan is connected with a driving motor.

[0004] Preferably, the first filter device and the second filter device have the same structure. The first filter device includes a sliding insertion frame. Side mesh plates are arranged on both the left and right sides of the sliding insertion frame. An insertion strip is arranged at the bottom of the sliding insertion frame, and a handle is arranged at the front end of the sliding insertion frame. Filter cotton with several irregular round holes is placed inside the first filter device, and a filter screen is placed inside the second filter device.

[0005] Preferably, an atomizing nozzle is arranged on the filter box. An atomizer is arranged at the rear end of the atomizing nozzle, and a water tank is connected to the rear end of the atomizer.

[0006] Preferably, an air outlet pipe is connected to one side of the fan.

[0007] The beneficial effects of the utility model are as follows: The structure of the utility model is reasonably designed and easy to use. The setting of the grille can prevent larger cloth strips and other garbage from entering the air supply pipe, thus affecting the normal operation of the filter dust removal device. Moreover, the staggered setting of the filter cotton and the filter screen can perform multi-filtering, thereby improving the filtering effect of the filter dust collector.

Detailed implementation manners

[0012] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0013] Any feature of this specification, unless specifically described, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically described, each feature is only an example in a series of equivalent or similar features.

[0014] Such as Figure 1 , 2 shown, a multi-filter dust removal device includes an air inlet 1, a filter box 6 and a fan 12. A grille 2 is arranged at the lower end position inside the air inlet 1. The lower end of the air inlet 1 is connected with an air supply duct 3. The end of the air supply duct 3 is connected with a filter box 6. A plurality of rectangular notches are opened on the left and right side walls of the filter box 6. A sliding groove 4 is arranged in the rectangular notch. A limiting plate 5 is arranged at the end of the sliding groove 4. A first filter device and a second filter device are inserted in the rectangular notch in a reverse symmetric and staggered manner. A fan 12 is connected to the rear end of the filter box 6. A driving motor 13 is connected to the rear end of the fan 12.

[0015] The first filter device and the second filter device have the same structure. The first filter device includes a sliding insertion frame. Side net plates 16 are arranged on both the left and right sides of the sliding groove frame. An insertion strip 17 is arranged at the bottom of the sliding insertion frame. A handle is arranged at the front end of the sliding insertion frame. Filter cotton 15 with a number of irregular round holes is placed inside the first filter device. A filter net 11 is placed inside the second filter device.

[0016] An atomizing nozzle 8 is arranged on the filter box 6. An atomizer 9 is arranged at the rear end of the atomizing nozzle 8. A water tank 10 is connected to the rear end of the atomizer 9.

[0017] One side of the blower 12 is connected with an air outlet pipe 14.

[0018] During use, the first filtering device with the filter cotton 15 and the second filtering device with the filter net 11 are installed in a reverse symmetric and spaced manner in each rectangular slot, and the inserting strips 17 at the bottoms of the first filtering device and the second filtering device are slidably inserted into the sliding slots 4, and then fixed by bolts.

[0019] The driving motor 13 drives the blower 12 to suck air. At this time, the air inlet 1 conveys the air with dust and particulate matter into the air supply pipe 3, and then the air supply pipe 3 conveys the air into the filtering box 6, and passes through the multiple filtrations of the filter cotton 15 and the filter net 11 in sequence. During this process, the atomizer 9 atomizes the water in the water tank 10 and sprays it out through the atomizing nozzle 8, so that the dust and particulate matter contained in the air are more likely to adhere to the filter cotton 15 and the filter net 11, thereby improving the filtering effect of the filter cotton 15 and the filter net 11, and then discharging the filtered air from the air outlet pipe 14.

[0020] The beneficial effects of the present utility model are as follows: The structure of the present utility model is reasonably designed and convenient to use. The setting of the grille can prevent larger garbage such as cloth strips from entering the air supply pipe, thus affecting the normal operation of the filtering and dust removal device, and the staggered setting of the filter cotton and the filter net can perform multiple filtrations, thereby improving the filtering effect of the filter and dust collector.

[0021] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, and any new method or process step or any new combination disclosed.
