Description

Technical Field

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

[0002] Workshop production refers to the process in which raw materials and semi-finished products are processed, assembled, inspected, and finally formed into finished products in an industrial enterprise according to a certain process sequence and organizational method. During the workshop production process, air purifiers are needed to collect dust in the air environment of the production workshop. During the use of air purifiers, the flow of air will produce sound, so a noise reduction device is needed to reduce the decibels of the sound.

[0003] Although the prior art has many benefits during use, it still has the following problems: it lacks a cleaning structure for the air inlet duct of the air purifier, which causes media such as cloth strips or films in the production environment to adhere to the outer wall of the grille inside the air inlet duct. The media will sway with the flow of the airflow, generating a lot of noise. Utility Model Content

[0004] The purpose of the utility model is to provide a workshop production noise reduction device to solve the problems raised in the above background technology.

[0006] When using a workshop production noise reduction device in the technical solution, the screw body drives the sliding block and the connecting rod to move horizontally, thereby pushing the foreign objects on the outside of the grid plate to move through the scraper, and the electric push rod drives the baffle plate to retract into the dust hood. The external vacuum cleaner can collect the foreign objects on the outside of the scraper through the dust pipe to prevent the foreign objects from generating noise on the outside of the grid plate.

[0007] Preferably, a connecting pipe is plugged and installed on the outer wall of one side of the air inlet cover, and the connecting pipe is connected to the inside of the air inlet cover and is connected to the air purifier.

[0008] Preferably, the lead screw body passes through the outer wall of one end of the air inlet cover and is provided with a motor body, and the motor body is connected to the outer wall of the air inlet cover. The motor body drives the lead screw body to work.

[0009] Preferably, the connecting rod is designed in a rectangular shape and is located on one side of the grid plate.

[0010] Preferably, the outer wall of the connecting rod is equipped with equidistant and parallel scrapers, the scrapers are located between the grid plates, and the scrapers are in contact with the outer wall of the grid plates. The scrapers scrape and clean foreign matter on the outer wall of the grid plates.

[0011] Preferably, a dust suction pipe is plugged and installed on one side of the lower end of the inner wall of the dust hood, and the dust suction pipe is connected to the inside of the dust hood. The dust suction pipe is connected to an external vacuum cleaner.

[0012] Preferably, the dust hood is designed in a rectangular shape, and the dust hood is connected to the inside of the air inlet hood.

[0013] Preferably, the baffle is designed in a rectangular shape and is located inside the dust hood. The baffle shields the dust hood.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model achieves the effect of cleaning the grid plate by arranging a scraper, a baffle and a dust suction pipe. The screw body drives the sliding block and the connecting rod to move horizontally, thereby pushing the foreign objects on the outside of the grid plate to move through the scraper, and the electric push rod drives the baffle plate to retract into the dust hood. The external vacuum cleaner can collect the foreign objects on the outside of the scraper through the dust suction pipe, avoiding the foreign objects from generating noise on the outside of the grid plate, thereby achieving the purpose of reducing the noise of the equipment and ensuring the quietness of the equipment during use.
