A multi-directional airflow adjustable dust suction port assembly

Abstract

This utility model provides a multi-directional airflow adjustable dust collection port assembly, including: a main housing, an upper airflow pipe assembly, and side guide pipes. The main housing has a rectangular structure. Three sets of upper airflow pipe assemblies are provided at the center of the upper end of the main housing for connecting and guiding external dust collection pipes. Compared with the prior art, this utility model has the following advantages: First, the main housing is installed in the working area by a rear fixing bracket to ensure that the dust cover completely covers the outside of the assembly. During operation, the external dust collection pipe is connected to the pipe port of the upper airflow pipe assembly in sequence. The double-threaded structure of the inner connector is used to achieve a sealed connection with the corrugated bend. Before starting the dust collection fan, it is confirmed that the flange pipe and the lower end of the corrugated bend are fixed with bolts. When the fan is running, the airflow is synchronously drawn in from the symmetrically arranged upper and lower airflow pipe assemblies, and forms a vortex through the spiral guide groove to accelerate dust collection. The side guide pipes can be manually adjusted to assist the airflow direction and enhance local suction.

Description

Technical Field

[0001] This utility model belongs to the field of vacuum inlet adjustment technology, and relates to a multi-directional airflow adjustable vacuum inlet component. Background Technology

[0002] Existing multi-directional airflow dust extraction port components cannot effectively guide dust during airflow carrying dust, resulting in the following main drawbacks: First, dust particles tend to move turbulently without guided airflow, leading to a significant reduction in localized suction efficiency, especially at the edges and corners of the suction port, where dead air zones easily form, causing some dust to remain uncaptured. Conventional solutions include: one, increasing the negative pressure at the suction port by increasing fan power to enhance suction and compensate for insufficient guidance; two, reducing the suction port area to concentrate airflow and increase local wind speed. However, these methods have significant drawbacks: increasing negative pressure significantly increases energy consumption, exacerbates airflow noise, and may cause adsorption damage to fragile surfaces. Therefore, there is an urgent need for a multi-directional airflow adjustable dust extraction port component to solve these problems. Utility Model Content

[0005] In a preferred embodiment, the lower right end of the corrugated bend is connected and fixed to the flange connector, and the flange connector is sealed and fixed to the suction end of the dust collector by a number of bolts.

[0006] In a preferred embodiment, the flange connection to the vacuum fan is sealed with sealant. The upper and lower airflow pipes are of the same specification and are mirror-image of the vacuum fan, extending through the upper and lower sides of the main housing. In actual use, the main housing is first installed in the work area using the rear mounting bracket to ensure that the dust cover completely covers the outside of the components. During operation, the external vacuum pipes are connected sequentially to the pipe ports of the upper airflow pipe group. The double-threaded structure of the inner connector is used to achieve a sealed connection with the corrugated bend. Before starting the vacuum fan, it is confirmed that the flange connection and the lower end of the corrugated bend are fixed with bolts, and sealant is filled at the connection to ensure airtightness. When the fan is running, the airflow is synchronously drawn in from the symmetrically arranged upper and lower airflow pipes, forming a vortex through the spiral guide groove to accelerate dust collection.

[0010] In a preferred embodiment, the lower center of the main housing is provided with three sets of downward airflow pipes for connecting and leading out external suction pipes. The three sets of upward airflow pipes correspond one-to-one with the three sets of downward airflow pipes, and each set of upward airflow pipes is connected to a set of downward airflow pipes through a set of suction fans. In actual use, multi-directional balanced suction is achieved through the coordinated work of the three sets of fans and the six sets of airflow pipes. The three-point support of the rear fixed frame ensures the stability of operation, and the dust cover can avoid secondary pollution. During use, the correspondence between the upper and lower airflow pipes should be maintained, and the wear of the spiral guide groove should be checked regularly to ensure the spiral effect of the airflow.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: First, the main housing is installed in the working area through the rear fixing frame to ensure that the dust cover completely covers the outside of the component. During operation, the external suction pipe is connected to the pipe port of the upper airflow pipe group in sequence.
