Description

Technical Field

[0001] The utility model relates to the technical field of filtering and ventilating equipment, in particular to filtering and ventilating equipment for a factory building. Background Art

[0002] Ventilation, also known as air exchange, is the use of mechanical or natural methods to deliver enough fresh air into the indoor space, while expelling the dirty air that does not meet the hygiene requirements of the room, so that the indoor air meets the hygiene requirements and the needs of the production process. The various facilities that complete the ventilation work in the factory building are collectively called ventilation equipment.

[0003] The utility model patent with the patent authorization announcement number CN214791652U discloses a factory ventilation and filtering equipment, including a cylindrical cylinder, a fixed bracket is fixedly provided in the middle of the cylindrical cylinder, a double-axis motor is fixedly provided in the middle of the fixed bracket, an annular steel ring is fixedly provided on one side of the double-axis motor in the inner cavity of the cylindrical cylinder, a fine filter is fixedly provided in the inner cavity of the annular steel ring, a first shaft is fixedly provided at one end of the double-axis motor, and the first shaft passes through the fine filter. By setting the fine filter, the fine filter can filter the dust in the factory, by setting the double-axis motor, the double-axis motor can drive the strip brush and the fan blade to rotate at the same time, the strip brush can clean the dust on the surface of the fine filter, and the filter hole can be prevented from being blocked and affecting the use. The rotation of the fan blade can discharge the air in the factory to the outside, so that the indoor air meets the hygiene requirements and the needs of the production process, and by setting the cover plug and the coarse filter, the parts inside the cylindrical cylinder can be protected without affecting the exhaust.

[0004] In the above-mentioned prior art, during the use of the filtering and ventilation equipment, the dust on the surface of the filter is cleaned by a brush. However, since the bristles of the brush are relatively fine, the bristles will be inserted into the filter holes of the filter when moving, which makes it easy to push dust impurities into the filter holes of the filter, and the filter cannot have a good anti-blocking effect. In addition, the dust impurities filtered out by the filter are light in weight and are affected by static electricity. It is difficult to discharge them through the chip discharge port by their own gravity alone, which makes it inconvenient to collect and process the dust impurities. Therefore, improvement is needed.
