Description

Technical Field

[0001] The utility model relates to the technical field of workshop air filtering, in particular to a workshop air filtering device. Background Art

[0002] In the production workshop of scrap aluminum engraving, the air in the workshop needs to be filtered. Otherwise, the dust and volatilization of waste liquid generated in the production process can be easily inhaled by the human body and cause harm to the human body. Therefore, an air filter is needed. The air filter is a device that captures dust from the gas-solid two-phase flow through the action of porous filter materials and purifies the gas; it purifies the air with low dust content and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] When the air filter in the prior art filters the workshop air, dust and volatile water vapor of the exhaust liquid are easily adsorbed on the filter net, which causes clogging of the filter net after a long period of accumulation, thereby affecting the filtration efficiency of the filter net and failing to collect the volatile waste liquid. For this reason, we propose a workshop air filtration device. Utility Model Content

[0004] In view of the above problems, the utility model provides a workshop air filtering device, which can drive a strip brush body to rotate through fan blades and a rotating rod under the action of a suction fan, so as to clean one side of the filter screen. This can prevent the filter screen from being blocked after long-term use, thereby ensuring the filtering efficiency of the air filter for air.

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0022] Example:

[0023] like Figure 1-Figure 4 As shown, a workshop air filtering device includes a shell 1, a positive speaker cover 4 is fixedly connected to the left side of the shell 1, a suction fan 2 is arranged on the right side of the shell 1, a partition 12 is fixedly connected to the inner side of the shell 1, a rotating rod 14 is movably connected to the right side of the partition 12 through a bearing, a fan blade 16 is arranged on the right end of the rotating rod 14, a strip brush body 13 is fixedly connected to the outer side of the rotating rod 14, a filter screen 15 is arranged on the outer side of the partition 12, and a collecting box 6 is arranged below the shell 1.

[0024] The working principle of the above technical solution is as follows:

[0025] Under the action of the suction fan 2, suction is generated to suck the air in the shell 1 to flow outside the shell 1. At this time, the inside of the shell 1 is in a negative pressure state, and the air in the workshop is sucked in through the positive horn cover 4. Under the action of the filter 15, the dust in the air and the water vapor volatilized by some waste liquid are blocked. When the suction fan 2 is working, the fan blades 16 rotate when the suction is generated, thereby driving the strip brush body 13 to rotate through the rotating rod 14, cleaning the filter 15, and filtering it. The filtered impurities and water vapor enter the collection box 6 for collection.

[0026] In another embodiment, if Figure 2 As shown, a grille 5 is fixedly connected to the left side of the positive speaker cover 4, the right side of the positive speaker cover 4 is connected to the inside of the shell 1, and a reverse speaker cover 8 is fixedly connected to the inside of the shell 1.

[0027] Under the action of the grille 5, the opening of the positive horn cover 4 is blocked to prevent the entry of excessive debris, and under the action of the reverse horn cover 8, the air is gathered to drive the fan blades 16 to rotate.

[0028] In another embodiment, if Figure 4 As shown, a ventilation slot is provided on the outer side of the partition 12, and a filter screen 15 is fixedly connected to the inner side of the ventilation slot.

[0029] The installation of the filter 15 is facilitated by the ventilation slot, and the sundries and volatile water vapor in the workshop air are filtered by the filter 15.

[0030] In another embodiment, if Figure 2 As shown, a bracket 3 for installing the device is arranged on the top of the shell 1 , and a collecting tank 7 is arranged on the bottom of the shell 1 .

[0031] The support 3 facilitates the device to be fixed at a suitable position in the workshop, and the collecting trough 7 facilitates the filtered debris and water vapor to enter the collecting box 6 below.

[0032] In another embodiment, if Figure 2 As shown, an external threaded tube 9 is fixedly connected to the bottom of the shell 1, a screw hole is provided on the top of the collection box 6, and the external threaded tube 9 is threadedly connected to the inner side of the screw hole.

[0033] The external threaded tube 9 and the screw hole facilitate the installation and subsequent disassembly of the collection box 6, and the collection box 6 can be removed regularly for cleaning.

[0034] In another embodiment, if Figure 3 As shown, a filter screen 10 is fixedly connected to the inner side of the collection box 6 , and the top of the external threaded tube 9 is connected to the inside of the collection tank 7 .

[0035] Under the action of the filter screen 10, the collected debris and water vapor are separated into solid and liquid, so that the collected waste liquid volatilization water vapor is collected and processed uniformly.

[0036] In another embodiment, if Figure 3 As shown, a slope is arranged at the bottom of the collecting box 6 , a sewage discharge pipe 11 is arranged on the right side of the collecting box 6 , and a valve is arranged in the middle of the sewage discharge pipe 11 .

[0037] The slope facilitates the collection of the volatile water vapor, which is then discharged through the sewage pipe 11, and the sewage pipe 11 is controlled by the valve.

[0038] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
