Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust collecting equipment, in particular to indoor decoration construction dust collecting equipment and method. BACKGROUND

[0002] At present, when a new house is decorated, the decoration workers first use lime to level, and then scrape putty powder. In order to make the local wall flat, after the whole putty powder is dried, fine sandpaper is needed to polish manually. In this process, a large amount of material will fall off, that is, the common dust. Polishing putty powder is also the most likely to produce dust pollution in the decoration process.

[0003] The application number CN202011580411.4 is an indoor decoration dust isolation equipment. The air suction assembly includes a fan arranged at the air inlet position of the installation box. The filter assembly is located between the air inlet and the air outlet. The filter assembly includes a plurality of filter screens arranged in the installation box and a cleaning piece arranged on the installation box. There is a gap between the outer side of the filter screen and the inner wall of the installation box, which facilitates the absorption of dust generated during decoration and reduces the impact on the working process.

[0004] However, in actual use, the putty dust is usually fine and easy to suspend in the air, which is difficult to settle. The external dust isolation equipment cannot complete the adsorption of dust in the first time, which makes it easy for workers to inhale dust. In addition, the putty dust has small density and is easy to be driven by air flow, so the diffusion range is wide. This makes it easy for workers to drive dust to flow when moving, which greatly reduces the collection effectiveness of dust. In addition, static electricity is generated when polishing putty, which makes the putty dust easily adsorbed on the surface of the wall. Therefore, it is necessary to wipe several times to clean, which increases the cleaning difficulty and time. When workers use the polishing equipment to polish putty, it is difficult to collect putty dust, which makes it difficult to clean dust and greatly reduces the collection efficiency of putty dust.

[0005] Therefore, the present application proposes indoor decoration construction dust collecting equipment and method to solve the above problems. SUMMARY

[0018] 2、The application realizes the locking connection between the driving ring and the limiting ring through the action of the electromagnetic locking assembly. When the driving ring rotates, the air guide ring is driven to rotate synchronously, and then the dust particles adsorbed on the surface of the construction site are scraped and cleaned through the rotating wiper. The annular pressure-bearing air bag is expanded to extrude the annular water storage bag, so that the water in the water storage bag is transported to the wiper through the water absorption cotton plate, the wettability of the wiper is increased, the water content is provided, the dust collection capacity is enhanced, and the dust capture efficiency is accelerated. After the driving ring and the limiting ring are locked, the outer side of the fan blade is attached to the construction site, and the surface of the construction site is scraped and cleaned.

[0019] 3、The driving ring in the application drives the dovetail sliding seat to move in the dovetail slide through the fan blade, extrudes the gas storage bag, and makes the gas in the gas storage bag input into the cleaning gas bag through the gas input pipe, so that the cleaning gas bag is expanded, and then the inner recessed arc of the fan blade is reduced. When the cleaning gas bag is expanded to a flat outer surface, the wind speed generated when the fan blade rotates is reduced, the combination time of dust and water in the air is increased, and the combination force of dust and water is improved.

[0020] 4、When the gas storage bag is completely extruded, the gas in the gas storage bag is completely introduced into the cleaning gas bag, so that the surface of the cleaning gas bag is expanded to an outward convex arc, the fan blade cannot do work on the air, the rotation of the fan blade cannot cause negative pressure, on the contrary, the rotation of the fan blade can utilize the resistance of the air to the fan blade, so that the air can clean the surface of the cleaning gas bag, that is, the dust on the surface of the fan blade is cleaned. The gas in the annular pressure-bearing air bag is introduced into the annular gas storage cavity through the gas guide pipe, and then is sprayed from the air jet head. When the fan blade rotates, the high-speed airflow sprayed from the air jet head directly faces the cleaning gas bag, completes the blowing and cleaning of the cleaning gas bag, and realizes the self-cleaning effect of the fan blade.

9. The interior finishing construction dust collection apparatus of claim 4, wherein: The dust collector (10) further comprises a dust collecting box, and an air inlet pipe is fixed on the dust collecting box and connected with the dust collecting pipe (13), and an air outlet pipe is arranged at the bottom of the dust collecting box and fixedly provided with a filter screen.

10. A method for collecting dust in interior finishing work, which is implemented using the interior finishing work dust collecting apparatus according to any one of claims 1 to 9, characterized by: The dust collecting method comprises the following steps: S1: connecting the dust collecting pipe (13) and the dust collecting box, pressing the dust collector (10) on the construction site, and driving the dust cover (20) to flow after the driving of the driver (30), the gas outside the dust collector (10) enters the dust cover (20), and the dust at the construction site is driven to flow, and then enters the dust collecting box through the dust cover (20) and the dust collecting pipe (13) in sequence to be collected; S2: when the driver (30) works, the rotation of the fan blade (36) drives the air flow, the air guide ring (23) is pressed on the construction site, the dust at the construction site is collected based on the rotation of the fan blade (36), and the dust at the construction site is collected based on the rotation of the fan blade (36); S3: the annular electromagnet (15) is internally introduced with current, a magnetic attraction force is generated on the iron ring (28), the dust cover (20) is internally retracted to the dust collector (10), the air guide ring (23) is internally retracted to the dust collector (10), the space inside the dust collector (10) is reduced, the dust is quickly extracted from the dust collector (10), the annular pressure gas bag (14) is expanded after being extruded, the expanded part extrudes the annular water storage bag (29) along the outer edge of the fixed seat (21), the annular water storage bag (29) is also extruded, and then the water in the annular water storage bag (29) is rapidly permeated into the wiper blade (24) through the water absorbing cotton plate, the wiper blade (24) is improved in wetness, the amount of dust captured by the gas is increased, and the negative pressure air flow generated by the rotation of the fan blade (36) is discharged; S4: when the driving ring (37) and the limiting ring (27) are in contact, the electromagnetic locking assembly is actuated, the driving ring (37) and the limiting ring (27) are locked, the driving ring (37) is driven to rotate synchronously, the construction site is wetted and wiped by the rotating wiper blade (24), the side wall of the fan blade (36) is attached to the construction site, the construction site is scraped and cleaned, the construction site is cleaned, and the dust collection efficiency is improved. S5: After the locking of the driving ring (37) and the limiting ring (27), in the process of continuously shrinking the air guide ring (23) to the inside of the dust collector (10), at this time, the driving ring (37) drives the swallow-tailed sliding seat (35) to move in the swallow-tailed sliding groove (34) through the fan blade (36), and the gas in the gas storage bag (39) is input into the cleaning gas bag (38) through the gas conveying pipe, so that the cleaning gas bag (38) is inflated, and then the inner concave arc of the fan blade (36) is reduced, the work done by the fan blade (36) when rotating is reduced, the wind speed generated by the fan blade (36) when rotating is reduced, the combination time of dust and moisture in the air can be increased, and the combination force of dust and moisture can be improved.
