Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a building workshop ventilator. Background Art

[0002] There are two ventilation modes for existing factory ventilators. One is a spherical or box-shaped ventilation shell installed on the top of the factory to ventilate the factory by itself, and the other is a ventilator that uses a high-power fan structure to blow air into the factory. The greater the power of the fan structure ventilator when it is working, the greater the suction force generated on its back. This type of ventilator can easily suck in dust and blow it into the factory again, so dust prevention measures must be taken for the ventilator, but ordinary dust prevention measures, such as adding dustproof nets, will reduce its ventilation efficiency, and this dust prevention measure is not suitable for high-power ventilators. Utility Model Content

[0003] In order to overcome the problem that high-power ventilators in the prior art easily suck in dust, and adding dust-proof nets will reduce ventilation efficiency, the utility model embodiment provides a building workshop ventilator. The technical solution is as follows:

[0004] A building workshop ventilator comprises a ventilation shell and a dust collection box sleeved on the air inlet of the ventilation shell, a honeycomb panel is arranged inside the dust collection box, and a first partition and a second partition are bolted to the front and rear ends of the dust collection box respectively; a spiral tube is arranged inside each through hole of the honeycomb panel, a guide hole is opened on the outer wall of the spiral tube, a plurality of circular holes with the same diameter as the two ends of the spiral tube are opened on the first partition and the second partition, and the two ends of the spiral tube are respectively aligned with the circular holes on the first partition and the second partition and are tightly connected.

[0005] Furthermore, a sound insulation sleeve is slidably provided inside the dust collection box, which can effectively reduce the noise generated by the machine.

[0006] Furthermore, a slide groove is provided on the inner wall of the dust collection box, and protrusions used in conjunction with the slide groove are fixed on the two outer side walls of the sound insulation sleeve. The protrusions slide in the slide groove, making it easy to disassemble and replace the sound insulation sleeve.

[0007] Furthermore, the honeycomb panel is arranged inside the sound insulation sleeve.

[0008] Furthermore, the sound insulation sleeve may be made of foam or sound insulation cotton.

[0009] Furthermore, each through hole of the honeycomb panel is sleeved with a steel pipe, the spiral pipe is arranged in the steel pipe, and a gap is left between the inner wall of the steel pipe and the outer wall of the spiral pipe, and dust can be stored in the gap.

[0010] Furthermore, both ends of the spiral tube are connected to connecting tubes respectively, and the spiral tube is aligned with and tightly connected to the circular holes on the first partition or the second partition through the connecting tubes, and the inner diameter of the circular hole of the partition is equal to or slightly smaller than the inner diameter of the connecting tube.

[0011] Furthermore, a shell is fixed to the bottom of the ventilation shell, and a pulley block is provided at the bottom of the shell to facilitate the movement of the device when used for temporary ventilation.

[0012] Furthermore, a fan is arranged in the ventilation shell.

[0013] The beneficial effect of the technical solution provided by the embodiment of the utility model is that the utility model allows air to enter in a spiral manner from the spiral tube inside the honeycomb panel, and can discharge dust and particulate impurities in the gas through the guide hole into the inside of the steel pipe, thereby reducing the entry of dust and impurities into the interior of the factory building. While having a certain filtering effect, since there is no need to set up dust-proof net components during the ventilation process, it will not affect the normal ventilation of the ventilator.
