Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of outer wall spraying and dust removal, and particularly discloses a dust collecting and purifying device for outer wall paint. BACKGROUND

[0002] During the construction of outer wall paint, a large amount of dust is inevitably generated, regardless of whether spraying, roller coating or wall surface pretreatment such as grinding is adopted. The conventional construction method of outer wall paint is extremely limited in dust treatment. Effective dust control measures are often lacking at the construction site, causing dust to spread freely, and workers are exposed to the environment full of paint dust for a long time, so that the respiratory system of the construction personnel is seriously threatened. The tiny particles in the dust may contain harmful substances, pigment particles and other impurities in the paint. Once these substances are inhaled into the lungs, the health and work efficiency of the construction personnel are seriously affected.

[0003] The existing dust collecting and purifying device for outer wall paint generates a large amount of paint dust when spraying the wall. During the spraying process, paint dust is inevitably generated. At this time, the original device cannot purify the dust, which is inhaled into the lungs of the construction personnel, thereby threatening the health of the construction personnel. When a large amount of dust is generated, the work efficiency of the construction personnel is affected. The present application provides a dust collecting and purifying device for outer wall paint, which can effectively solve the above problems. SUMMARY

[0004] The utility model aims at spraying the outer wall, can absorb the dust generated, and through the action of filtering, the dust is purified, thereby preventing the construction personnel from inhaling the dust into the lungs and affecting the physical and mental health. At the same time, the dust is purified, which protects the atmospheric environment to some extent and improves the work efficiency of the construction personnel.

[0005] The utility model is implemented by the following technical solutions:

[0006] A dust collecting and purifying device for outer wall paint, comprising a spraying mechanism, the spraying mechanism comprising a spraying gun, the bottom of the spraying gun being fixedly connected with a spraying pipe, one side of the spraying gun being provided with a plug-in mechanism, the top of the spraying gun being provided with a filtering mechanism used in cooperation with the plug-in mechanism;

[0007] As a further arrangement of the above-mentioned scheme, the plug-in mechanism comprises a dust collection cover movably sleeved outside the spraying gun, a clamping block movably plugged into the inside of the dust collection cover and equally distributed in the form of a circle, sliding blocks fixedly connected to the two sides of the clamping block, a hanging buckle fixedly installed on one side of the dust collection cover, and a limiting ring fixedly sleeved on the outer surface of the spraying gun.

[0008] The plurality of clamping blocks are arranged in a circumferential arrangement inside the dust cover, and the plurality of clamping blocks are located on the spray gun and can be inserted into the dust cover as needed, wherein the dust cover is made of transparent plastic material, the spray gun spraying angle can be observed through the dust cover, and the paint dust generated during spraying can be covered by the dust cover, which is beneficial to the next purification.

[0009] As a further arrangement of the above scheme, the insertion mechanism further comprises a first spring fixedly installed on the side of the clamping block opposite to the dust cover, one side of the limiting ring is provided with a hole matched with the hanging buckle, and a stand is fixedly installed on the inner surface of the hole.

[0010] The hook of the hanging buckle is made of elastic material, the hook of the stand is clamped on the outer side of the stand, so that the rotation of the dust cover is limited, and the hanging buckle can freely move in the groove of the limiting ring, so that the hanging buckle and the stand are well inserted.

[0011] As a further arrangement of the above scheme, the filtering mechanism comprises a filter box fixedly installed on the top of the spray gun, a double fork pipe is fixedly communicated with the top of the filter box, the other end of the double fork pipe is fixedly connected with the dust cover, an air extractor is adaptively installed on the bottom of the filter box, and a first filter plate and a second filter plate are movably inserted into one side of the filter box.

[0012] The double fork pipe is a bifurcated pipe, the bifurcated ends of the double fork pipe are fixedly installed on the top and bottom of the dust cover, so that the dust can be completely absorbed, and the dust absorption efficiency is improved, the first filter plate is located on the top of the second filter plate, and the two divide the filter box into three spaces, so that the dust is filtered from top to bottom, and the filtered gas can be discharged through the action of the air extractor.

[0013] As a further arrangement of the above scheme, the filtering mechanism further comprises fixed blocks fixedly installed on one side of the filter box and symmetrically distributed, opposite sides of the two fixed blocks are rotatably connected with limiting clamping blocks, one end of the limiting clamping block is rotatably connected with a roller, and the roller is located on one side of the first filter plate, and a second spring is fixedly arranged on the side of the limiting clamping block opposite to the filter box.

[0014] The limiting clamping blocks are two groups and symmetrically distributed, the limiting clamping blocks are arranged on both sides of the first filter plate, and the first filter plate is also arranged on both sides of the second filter plate, so that the first filter plate and the second filter plate are respectively fixed in the filter box, preventing the first filter plate and the second filter plate from being separated from the filter box during use, causing the consequence of being unable to remove dust, and due to the action of the roller, the first filter plate can be easily pulled out through external force while limiting the movement of the first filter plate, and through double filtration, the effect of purification and dust removal can be better achieved.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By using the dust hood, the spray gun's fan-shaped spray pattern can be completely covered when spraying paint on the wall, thus completely covering the dust generated during the spraying process and preventing the dust from being inhaled into the worker's lungs. This improves both safety and the worker's work efficiency.

[0017] 2. Through the action of the first and second filter plates, dust can be filtered twice, thus preventing harmful substances from appearing in the exhaust gas. Under the action of the rollers, the first and second filter plates can be quickly pulled out when replacing them, thereby improving the replacement efficiency and not affecting the spraying work on the wall.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should fall within the scope of protection of the present application.

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments. Figures 1-5 The present application will be described in detail below with reference to the drawings and in combination with the embodiments. Embodiment 1

[0027] Embodiment 1 discloses a dust collection and purification device for exterior wall paint, referring to the drawings Figure 1 The main structure includes a spraying mechanism 100, the spraying mechanism 100 includes a spraying gun 101, the bottom of the spraying gun 101 is fixedly connected with a spraying pipe 102, one side of the spraying gun 101 is provided with a plug-in mechanism 200, and the top of the spraying gun 101 is provided with a filtering mechanism 300 used in cooperation with the plug-in mechanism 200.

[0028] Referring to the drawings Figure 4 and referring to the drawings Figure 5 The filtering mechanism 300 includes a filter box 301 fixedly installed at the top of the spraying gun 101, the top of the filter box 301 is fixedly connected with a double-tube pipe 302, the other end of the double-tube pipe 302 is fixedly connected with the dust cover 201, the bottom of the filter box 301 is adaptively installed with an air extractor 305, and the side of the filter box 301 is movably plugged with a first filter plate 303 and a second filter plate 304. The double-tube pipe 302 is a bifurcated pipe, and the bifurcated ends are fixedly installed at the top and the bottom of the dust cover 201, so that the dust can be completely absorbed and the dust collection efficiency is improved.

[0029] The filtering mechanism 300 further includes fixed blocks 306 fixedly installed on one side of the filter box 301 and symmetrically distributed, the opposite side of the two fixed blocks 306 is rotatably connected with a limiting clamping block 307, one end of the limiting clamping block 307 is rotatably connected with a roller 308, and the limiting clamping block 307 is fixedly provided with a second spring 309 on the opposite side of the filter box 301.

[0030] The working principle of the embodiment is as follows: dust is absorbed through the plug-in mechanism 200, and then the first filter plate 303 and the second filter plate 304 are manually inserted into one side of the filter box 301 in sequence. When the end of the first filter plate 303 moves to the outside of the roller 308, the limiting block 307 is manually pressed, the limiting block 307 drives the second spring 309 to deform, and the limiting block 307 simultaneously drives the roller 308 to move outward. At this time, the first filter plate 303 is pushed to tightly adhere to the filter box 301. At this time, the force applied to the limiting block 307 is removed, and the second spring 309 pushes the limiting block 307 to move reversely under the action of the second spring 309. The limiting block 307 drives the roller 308 to press on one side of the first filter plate 303, so as to fix the first filter plate 303 on one side of the filter box 301. The principle is the same as above. The other end of the first filter plate 303 and the two ends of the second filter plate 304 are pressed respectively, so as to fix the first filter plate 303 and the second filter plate 304 on one side of the filter box 301. When the first filter plate 303 and the second filter plate 304 need to be replaced, they can be directly pulled out. After installation, the operation of the air extractor 305 is controlled. Since one end of the double-tube pipe 302 has two heads and is fixed in communication with the dust cover 201, and the other end is communicated at the top of the filter box 301, dust splashed in the inner cavity of the dust cover 201 at the top and the bottom can be simultaneously absorbed. The dust is filtered through the action of the first filter plate 303 and the second filter plate 304. Finally, the filtered gas is discharged under the action of the air extractor 305. Embodiment 2
