Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to an impeller dust suction device. Background Art

[0002] The dust generated in industrial production may contain harmful substances, such as silicon dust, coal dust, metal particles, etc. These tiny dust particles can be inhaled by the human body, leading to occupational diseases such as pneumoconiosis or more serious health problems. Especially in industries such as food processing, pharmaceuticals, and electronic assembly, a very clean environment is required to ensure the purity and quality of the products, and dust will affect the quality of the products. Secondly, the accumulation of dust on equipment and machinery may lead to reduced efficiency, premature wear and increased failure rate. Regular dust removal can keep mechanical equipment in good operating condition and extend its service life, so dust collection and dust removal are usually required in processing workshops.

[0003] Existing industrial vacuum cleaners usually use high-power motors to drive fans to generate strong suction to remove dust and particles. These devices will generate high noise levels when in operation. Long-term exposure to workers may cause hearing damage and affect the overall noise environment in the workplace. Secondly, traditional industrial vacuum cleaners are large in size, occupy a large amount of workshop space, and are difficult to move. Utility Model Content

[0004] The purpose of the utility model is to provide an impeller dust collecting device with low noise and miniaturized structure, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0007] It can be seen that, compared with the traditional high-power fan dust collection system, the impeller suction mechanism uses the rotation of the impeller to generate suction. The impeller design uses the principle of fluid mechanics to optimize the shape, size and arrangement of the blades, thereby reducing turbulence and noise in the airflow, and has a good mute effect. At the same time, it can maintain efficient airflow and improve the dust collection effect. In addition, compared with the traditional industrial dust removal system, this device integrates the structure of each component inside and outside the cabinet, optimizes the overall structural layout, makes the equipment as a whole tend to be miniaturized, reduces the space occupied by the equipment, and is conducive to the layout of the workshop. At the same time, the miniaturized layout combined with the universal wheels at the bottom of the cabinet facilitates overall transfer and is highly practical.

[0008] Furthermore, the impeller suction mechanism includes a mounting frame installed in the third cavity, a mounting seat fixed on the top of the mounting frame, an impeller body installed above the mounting seat, and a drive motor fixed below the mounting seat and controlled by a variable frequency drive. The mounting seat has the ability to rotate, and the output shaft of the drive motor passes through the mounting seat and is fixedly connected to the main shaft of the impeller body.

[0009] The driving motor can drive the impeller body to rotate, thereby generating suction to achieve the dust collection effect. In addition, the driving motor is controlled by a variable frequency drive.

[0012] Furthermore, a hollow bottom bracket formed by a plurality of horizontal and vertical bars vertically crossed and fixed is provided at the bottom of the frame, an outer frame is fixed around the filter, the filter and the outer frame are installed in the frame and located above the hollow bottom bracket, and the outer frame is fastened to the hollow bottom bracket by fastening screws.

[0013] A hollow base support is arranged at the bottom of the frame to provide multi-point support for the filter and the outer frame, thereby ensuring the firmness of the filter installation and preventing the filter from being excessively deformed and bent due to strong airflow and affecting the filtering effect. At the same time, the outer frame and the filter are fixed to the hollow base support with fastening screws, so that the filter and the outer frame are detachable, which facilitates the regular disassembly and cleaning of the filter.

[0014] Furthermore, the air inlet mechanism includes an air inlet duct and an air inlet channel. The air inlet duct is arranged on one side of the cabinet, and the air inlet channel is arranged on one side of the first cavity in the cabinet. The air inlet duct extends into the cabinet and communicates with the air inlet channel. An air inlet hole connected to the air inlet channel is provided on the side wall of the first cavity above the frame, and the air inlet channel is connected to the first cavity through the air inlet hole.

[0015] Under the action of suction, external air is sucked into the first cavity through the air inlet pipe, the air inlet channel and the air inlet hole in sequence.

[0016] Furthermore, the drainage mechanism includes a first discharge pipe, a second row of pipes and an outer row of pipes. The first discharge pipe is arranged in the cabinet and located on the side of the second cavity and is communicated with the third cavity. The second row of pipes is arranged in the cabinet and located on the side of the first cavity. The outer row of pipes is arranged on the top of the cabinet. The top of the second row of pipes is communicated with the outer row of pipes, and the bottom of the second row of pipes is communicated with the top of the first discharge pipe.

[0017] The air after dust is filtered out can be discharged from the third cavity to the outside through the first discharge pipe, the second discharge pipe and the outer discharge pipe in sequence.
