Description
Technical Field
[0001] This utility model belongs to the field of dust recovery technology, specifically relating to a composite admixture dust recovery device. Background Technology
[0002] Composite admixtures are building materials that are optimized and formulated by multi-stage ball milling in series with high-performance additives, using ultrafine silica powder, highly active mineral powder, industrial by-products such as volcanic ash and stone powder. In the production and processing of composite admixtures, dust recovery devices are usually used to recover and treat the dust generated during the production and processing.
[0003] According to the patent announcement number CN221155927U, a low-consumption dust recovery device for concrete processing is known prior art. Although this patent has the advantage of being able to recover dust, the technical solution of this patent still has the following defects in actual use: Since the dust is directly absorbed by the exhaust fan, the dust is very easy to clog the exhaust fan vent. Long-term use will easily lead to vent blockage, which is not conducive to ensuring the dust absorption effect and efficiency. At the same time, the whole device does not have a knocking mechanism. During the dust suction and conveying process, the dust is very easy to adhere to the inner wall of the box, affecting the conveying efficiency. In addition, the sieve cannot be vibrated during screening, which easily leads to sieve hole blockage, affecting the screening effect and failing to achieve the purpose of screening coarse and fine powder. The effect is poor and the efficiency is low. Utility Model Content

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0026] Please see Figure 1 This utility model provides a composite admixture dust recovery device, including a box body 1. The box body 1 has a recovery chamber 10 and a screening chamber 9 inside. The front side of the screening chamber 9 is movably connected to the box door 2 by a hinge, so as to realize the purpose of opening and closing the screening chamber 9 and to facilitate the convenient handling of the screening frame 73. The bottom of the box door 2 is fixedly connected to the box body 1 by studs. A handle is fixedly connected to the surface of the box body 1. A dust inlet 3 is fixedly connected to the top of the box body 1. Support legs 8 are fixedly installed at the bottom of the box body 1 near the four corners to achieve the effect of stable support for the device.
[0027] Please see Figure 2 The side of the housing 1 is fixedly installed with a suction component 5, a cleaning component 11 and a knocking component 4. The suction component 5 includes a fan 51 and a filter window 52. The fan 51 is fixedly installed on the side of the housing 1, and the filter window 52 is opened on the inner wall of the recycling bin 10. The air intake of the fan 51 corresponds to the filter window 52.
[0028] In this embodiment, the fan 51 operates and the filter window 52 creates a negative pressure inside the housing 1, thereby attracting and recovering dust through the dust inlet 3.
[0029] Please see Figure 2 and Figure 4The cleaning assembly 11 includes a second bearing 115, which is fixedly connected to the side of the housing 1. A second shaft 113 is rotatably connected inside the second bearing 115. One end of the second shaft 113 passes through the housing 1 and is fixedly connected to a cleaning brush 111. The cleaning brush 111 overlaps with the surface of the filter window 52. The other end of the second shaft 113 is fixedly connected to a movable plate 112. A driven gear 114 is fixedly connected to the surface of the second shaft 113. A second motor 116 is fixedly connected to the side of the housing 1. A drive gear 117 is fixedly connected to the output shaft of the second motor 116. The drive gear 117 meshes with the driven gear 114.
[0030] In this embodiment, under the action of the second motor 116 driving the active gear 117 and the driven gear 114 to mesh and rotate, the cleaning brush 111 and the movable plate 112 are driven to rotate. Through the contact between the cleaning brush 111 and the filter window 52, the surface of the filter window 52 is cleaned, so as to avoid dust clogging the filter window 52 and the air outlet of the fan 51 and affecting the recycling effect. Through the rotation of the movable plate 112, the movable rod 41 is struck, and then the hammer 42 is used to strike and vibrate the surface of the box 1.
[0031] Please see Figure 2 , Figure 6 and Figure 7 The striking component 4 includes a support frame 43, a first bearing 44 is fixedly connected to the inner side of the support frame 43, a first rotating shaft 46 is rotatably connected inside the first bearing 44, a movable rod 41 is fixedly connected to the surface of the first rotating shaft 46, a striking hammer 42 is fixedly connected to the bottom end of the movable rod 41, and a return spring 45 is sleeved on the surface of the first rotating shaft 46, with the two ends of the return spring 45 fixedly connected to the surfaces of the first rotating shaft 46 and the first bearing 44, respectively.
[0032] In this embodiment, by means of the rotation of the first rotating shaft 46 within the first bearing 44, and through the elasticity of the return spring 45, the movable plate 112, rotating with the second rotating shaft 113, strikes or separates the movable rod 41, causing the movable plate 112 to drive the striking hammer 42 to intermittently strike the surface of the box 1. This achieves the purpose of vibrating the dust adhering to the inner wall of the box 1 and causing it to fall, thus ensuring the effectiveness and efficiency of dust recovery.
[0033] Please see Figure 2 and Figure 3 A humidification component 6 is fixedly installed on the surface of the housing 1. The humidification component 6 includes a water storage tank 63. The water storage tank 63 is fixedly connected to the rear side of the housing 1. A water pump 64 is fixedly installed on the rear side of the water storage tank 63. A water guide pipe 61 is fixedly connected to one end of the water pump 64. Several atomizing nozzles 62 are fixedly connected to the side of the water guide pipe 61. The atomizing nozzles 62 are fixedly installed on the inner wall of the recycling bin 10.
[0034] In this embodiment, the water pump 64 operates to transport the crystal water pipe 61 in the water storage tank 63 to the atomizing nozzle 62 for atomization spraying, thereby humidifying the dust, increasing the weight of the dust, and facilitating the rapid falling of the dust to achieve the purpose of screening and recycling.
[0035] Please see Figure 2 and Figure 5 The internal structure of the housing 1 is slidably connected to a screening assembly 7, which includes two sliding plates 71. The two sliding plates 71 are slidably connected to the two sides of the inner wall of the screening chamber 9. The sides of the two sliding plates 71 are provided with grooves 72. Screening frames 73 are slidably connected in the grooves 72. A toothed plate 78 is fixedly connected to the top of one sliding plate 71. A support plate 75 is fixedly connected to the side of the housing 1. A first motor 76 is fixedly installed on the surface of the support plate 75. A half gear 77 is fixedly installed on the output shaft of the first motor 76. The half gear 77 meshes with the toothed plate 78. A telescopic spring 74 is fixedly connected between the inner side of the other sliding plate 71 and the housing 1.
[0036] In this embodiment, under the action of the first motor 76 driving the half gear 77 to rotate, the half gear 77 and the toothed plate 78 mesh and separate, and through the elastic cooperation of the telescopic spring 74, push the slide plate 71 to drive the screening frame 73 to move left and right and vibrate, thereby vibrating and screening the dust on the screening frame 73, so as to achieve the purpose of separating and recycling coarse powder and fine powder. With the sliding action of the screening frame 73 in the slide groove 72, the screening frame 73 can be easily taken out by opening the box door 2 to process the coarse powder stored inside, and to facilitate the export of the fine powder stored at the bottom of the screening chamber 9 for processing.
[0037] The working principle and usage process of this utility model are as follows: First, connect the dust emission port of the external composite admixture production and processing equipment to the dust inlet 3 of this device. Then, by controlling the operation of the fan 51, a negative pressure is formed inside the box 1 to attract the dust. The dust first enters the recovery bin 10. As the dust falls, by controlling the operation of the water pump 64, the water in the water storage tank 63 is atomized and sprayed through the water pipe 61 and the atomizing nozzle 62, so that the dust and water mist combine to increase the weight and fall quickly.
[0038] Then the dust falls into the screening frame 73. By controlling the first motor 76 to work, the half gear 77 is driven to mesh and rotate or separate from the tooth plate 78. With the help of the telescopic spring 74 to stretch and recover, the screening frame 73 is driven to move and vibrate left and right to screen the dust. Fine powder enters the bottom of the screening chamber 9 for storage, and coarse powder is stored in the screening frame 73.
[0039] During the dust collection and conveying process, the second motor 116 is controlled to operate, driving the active gear 117 and the driven gear 114 to mesh and rotate, causing the second rotating shaft 113 to rotate. First, the cleaning brush 111 rotates to clean the filter window 52, preventing dust from clogging the filter window 52. At the same time, the second rotating shaft 113 drives the movable plate 112 to rotate, and the movable plate 112 strikes the movable rod 41. With the help of the rotational engagement of the second rotating shaft 113 in the second bearing 115 and the elastic engagement of the return spring 45, the movable rod 41 drives the hammer to intermittently strike the box 1 to create vibration, which knocks the dust adhering to the inner wall of the box 1 and makes it fall down, ensuring the recycling effect.
[0040] After a period of use, the box door 2 can be opened, the sieve frame 73 can be taken out to process the recovered coarse powder, and the recovered fine powder in the sieve chamber 9 can be exported for processing.
[0041] In the above scheme, it should be noted that: during the process of humidifying and increasing the weight of dust using the atomizing nozzle 62, the dust will not be sprayed with excessive water mist, but only to accelerate the falling of the dust. At the same time, the humidity between the dust particles will not be too high, which facilitates the subsequent screening of the dust.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
