Description

Technical Field

[0001] The invention relates to the field of civil construction dust treatment, in particular to a dust collecting device. Background Art

[0002] In the field of civil construction, dust pollution has always been a thorny problem. In the traditional construction process, processes such as concrete mixing, stone cutting, and wood polishing continuously generate a large amount of dust. These dusts are scattered wantonly, not only causing serious damage to the surrounding environment of the construction site, causing a surge in the concentration of particulate matter in the atmosphere, affecting air quality, but also settling into the soil and water, changing the natural balance of the ecological environment. From the perspective of the health of construction workers, they are very likely to inhale harmful dust when exposed to high dust environments for a long time, causing various diseases such as silicosis and respiratory infections, which seriously threaten their lives and health. At the same time, dust also has many negative effects on construction itself. On the one hand, in delicate operations such as indoor decoration, dust adheres to walls and floors, destroying construction effects and reducing construction quality; on the other hand, diffuse dust affects workers' vision, and deposits on equipment to interfere with normal heat dissipation and operation of equipment, reducing construction efficiency. Against this background, industrial vacuum cleaners have emerged as an efficient dust collection device for civil construction, dedicated to solving the dust problem in civil construction.

[0003] In contrast to the prior art, a Chinese invention with publication number CN118874075A discloses a dust collection device and method for civil construction engineering construction, which uses dust particles of different specifications with different apertures for recycling and treatment. However, in actual operation, it is found that during civil construction, spray water is often required to treat the dust. After being collected by dust suction, the dust will form lumps on the surface of the filter. If the lumps accumulate, it will affect the efficiency of dust suction and the effect of purification and collection. Summary of the invention

[0004] The object of the present invention is to provide a dust collecting device in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A dust collection device, comprising a collection mechanism for installation and fixing, an air extraction power mechanism for providing power, and a power mechanism, wherein the air extraction power mechanism is installed outside the collection mechanism, a moving mechanism is arranged at the bottom of the collection mechanism, and a power mechanism is installed at the top of the collection mechanism, and further comprising an air intake filter mechanism for filtering dust, a cleaning component for cleaning the air intake filter mechanism in real time, and an oscillating component cooperating with the cleaning component;

[0007] The filter of the air intake filtering mechanism is arranged inside the outer shell of the collecting mechanism, a support rod is fixedly installed on the outside of the filter, a filter mounting frame is arranged at the bottom of the support rod, an inner supporting blade is arranged inside the filter, and the filter is fixedly arranged, the inner supporting blade is rotatably arranged inside the filter, the inner supporting blade is pressed tightly against the inner surface of the filter, the inner side of the inner supporting blade is connected to the main shaft of the power mechanism through the inner supporting frame, the inner supporting frame cooperates with the main shaft through an elastic component, and the oscillation component is installed at the bottom of the main shaft.

[0008] Preferably, a top frame is installed on the top of the support rod, the top frame is fixedly connected to the top cover of the collecting mechanism, and the top cover is arranged on the top of the outer shell.

[0009] Preferably: the adjustment mechanism includes an oscillation frame, intermittent blocks are arranged on both sides of the bottom of the main shaft, the oscillation frame cooperates with the intermittent blocks through intermittent grooves, a groove is formed on the upper end surface of the oscillation frame, the bottom of the filter mounting frame extends into the groove of the oscillation frame, a limiting block is arranged on the outside of the filter mounting frame, and a vertical limiting groove is arranged on the oscillation frame corresponding to the position of the limiting block.

[0010] Preferably: the interior of the inner support frame is a hollow structure, the main shaft vertically penetrates the inner support frame, the elastic component includes baffles arranged inside the inner support frame and on the main shaft, and a compression spring is arranged between the baffle of the main shaft and the baffle of the inner support frame.

[0011] Preferably, the air intake filter mechanism further comprises a cone and a coarse filter arranged on the front end surface of the shell.

[0012] Preferably, the intermittent groove is a cyclic conical groove, and one cycle includes an extrusion part and a release part.

[0013] Preferably, the inner supporting blades are spiral blades.

[0014] Compared with the prior art, the beneficial effects are as follows:

[0015] By combining the elastic component with the cleaning component, the inner supporting blades can move the filter from the inside to the outside for cleaning, and because the air intake from the cone forms a vortex between the filter and the outer shell, and the inner supporting blades are in the opposite direction of the vortex, the dust chaos effect inside is increased, so that it can be evenly filtered through the filter. In the later stage, when the inner supporting blades are used for cleaning and in conjunction with the oscillation component at the bottom, the instantaneous falling force can be used to slightly stretch the filter, thereby forcing the filter to be misaligned with the agglomerates, thereby improving the agglomerate removal effect.

[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 7 As shown, a dust collection device includes a collection mechanism 3 for installation and fixing and an air extraction power mechanism 2 and a power mechanism 5 for providing power, wherein the air extraction power mechanism 2 is installed outside the collection mechanism 3, a moving mechanism 1 is arranged at the bottom of the collection mechanism 3, and a power mechanism 5 is installed at the top of the collection mechanism 3, and also includes an air intake filter mechanism 4 for filtering dust and a cleaning component for cleaning the air intake filter mechanism 4 in real time and an oscillating component cooperating with the cleaning component;

[0029] The filter 42 of the air intake filtering mechanism 4 is arranged inside the outer shell 31 of the collecting mechanism 3, and a support rod 43 is fixedly installed on the outside of the filter 42, and a filter mounting frame 41 is arranged at the bottom of the support rod 43, and an inner supporting blade 62 is arranged inside the filter 42, and the filter 42 is fixedly arranged, and the inner supporting blade 62 is rotatably arranged inside the filter 42, and the inner supporting blade 62 is tightly pressed against the inner surface of the filter 42, and the inner side of the inner supporting blade 62 is connected to the main shaft 52 of the power mechanism 5 through the inner supporting frame 61, and the inner supporting frame 61 cooperates with the main shaft 52 through an elastic component, and the oscillation component is installed at the bottom of the main shaft 52.

[0030] In this embodiment, a top frame 44 is installed on the top of the support rod 43 , and the top frame 44 fixes the top cover 32 of the collecting mechanism 3 , and the top cover 32 is arranged on the top of the shell 31 .

[0031] In this embodiment, the adjustment mechanism 7 includes an oscillation frame 71, and intermittent blocks 75 are arranged on both sides of the bottom of the main shaft 52. The oscillation frame 71 cooperates with the intermittent blocks 75 through intermittent grooves 74. A groove is formed on the upper end surface of the oscillation frame 71. The bottom of the filter mounting frame 41 extends into the groove of the oscillation frame 71. A limiting block 72 is arranged on the outside of the filter mounting frame 41, and a vertical limiting groove 73 is arranged on the oscillation frame 71 at the position corresponding to the limiting block 72.

[0032] In this embodiment, the interior of the inner support frame 61 is a hollow structure, and the main shaft 52 vertically penetrates the inner support frame 61. The elastic component includes baffles arranged inside the inner support frame 61 and on the main shaft 52. An extrusion spring 611 is arranged between the baffle of the main shaft 52 and the baffle of the inner support frame 61. When the motor 51 drives the main shaft 52 to start, the main shaft 52 will start instantly. At this time, the extrusion spring 611 is compressed, and the outside of the inner support frame 61 and the filter screen 42 are in close contact with each other, and there is resistance. Then, the inner support blades 62 will scrape the inside of the filter screen 42 intermittently. At the same time, combined with the spiral characteristics of the inner support blades 62 themselves, the inner support blades 62 can also have an expanded displacement in the axial direction, thereby improving the effect of scraping the filter screen 42.

[0033] In this embodiment, the air intake filter mechanism 4 also includes a cone and a coarse filter screen arranged on the front end surface of the shell 31. The coarse filter screen prevents debris such as paper from being sucked in, and the air is compressed after passing through the cone, thereby increasing the internal air flow speed.

[0034] In this embodiment, if Figure 5 As shown, the intermittent groove 74 is a cyclic tapered groove, and one cycle includes a pressing portion and a releasing portion.

[0035] In this embodiment, the inner supporting blades 62 are spiral blades.

[0036] Working principle: After starting the motor 51, the main shaft 52 cooperates with the inner support frame 61 through the compression spring 611, and the inner support blade 62 rotates in the filter screen 42 after starting. At the same time, since the rotation direction of the inner support blade 62 is opposite to the vortex direction generated after the airflow enters, the dust in the internal space is improved. Since the space between the filter screen 42 and the outer shell 31 is a cylindrical structure, the dust is evenly adsorbed on the filter screen 42, which prevents the dust from accumulating in one place.

[0037] During the adsorption process, the filter screen 42 will be clogged after adsorbing dust, and in the field of civil engineering, atomized water will be sprayed to improve the dust reduction effect, so the dust will be collected after contacting the atomized water, and the collection mechanism 3 always provides suction, so the filter screen 42 will be concave inward, and at the same time, the wet dust will agglomerate after being adhered to the filter screen 42. At this time, the inner support blade 62 provides support from the inside to the outside to the concave filter screen 42 when rotating and scraping;

[0038] In addition, the intermittent block 75 on the main shaft 52 will cooperate with the intermittent groove 74, and the vibration frame 71 will be intermittently lifted. Since the vibration frame 71 has weight, after it drops instantly, it can not only provide vibration for the filter mounting frame 41, the support rod 43, and the filter 42, but also use the falling force to pull down the filter mounting frame 41, the support rod 43, and the filter 42, so that the filter undergoes vertical deformation, thereby improving the separation effect of the filter 42 and the agglomerates.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
