Description

Technical Field

[0001] The invention relates to the technical field of dust reduction equipment, and in particular to a dust reduction device for treating construction waste with strong adaptability. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated by construction units or individuals during the construction, laying, demolition and repair of various buildings, structures, pipe networks, etc. As the concept of environmental protection has become more popular, in order to achieve the goal of saving resources, recycling and reusing construction waste has become an inevitable trend.

[0003] For waste stone materials such as slag and building slabs, crushing is a common pre-recycling step. However, there is a more difficult problem with current crushing devices, which is that a large amount of dust is generated during the crushing process. In order to suppress the generation of dust, spraying water mist during the crushing process is a common dust reduction method.

[0004] The Chinese patent authorization publication number is CN111686866B, which is a construction waste crushing device for construction engineering and its use method, belonging to the field of construction engineering technology. Among them, a construction waste crushing device for construction engineering includes a crushing box and a garbage collection truck, the garbage collection truck is placed at the bottom of the crushing box, the upper and lower sides of the crushing box are respectively connected with a feed port and a discharge port, the crushing box is connected with a crushing mechanism, the outer wall of the crushing box is connected with a dust reduction box, the dust reduction box is respectively connected with a water supply box and a water sprinkling box, the water supply box and the water sprinkling box are connected with a first pipe and a second pipe, the bottom of the dust reduction box is connected with a water supply pipe, the end of the water supply pipe away from the dust reduction box is connected to the top of the water supply box, the outer wall of the water supply pipe is connected with a water pump, and the water pump is connected to the outer wall of the water supply box; the present invention is conducive to the reuse of water resources used for dust reduction, which is conducive to saving water resources and reducing the cost of crushing construction waste.

[0005] The above-mentioned existing technical solutions have the following defects: in the actual operation process, the volume of construction waste varies. When processing large-volume construction waste, the amount of dust generated by its crushing is more. If the amount of water mist sprayed is too small at this time, the dust reduction effect will inevitably be greatly reduced. On the contrary, if the amount of water mist sprayed is too large, for small-volume construction waste, it is easy to stick together. This bonding phenomenon will seriously affect the subsequent processing work, such as problems in screening, transportation and other links. Moreover, it is difficult for the existing device to effectively carry out special enhanced spray treatment for the crushing of large-volume construction waste. This defect makes the device not very applicable and cannot well cope with the crushing and dust reduction needs of construction waste of different volumes, which ultimately affects the overall dust reduction effect and also hinders the efficient recycling and reuse of construction waste to a certain extent.

The number of the arc blocks on the water blocking rod 104 is the same as the number of the powerful nozzles 103. The connection between each powerful nozzle 103 and the water pipe 101 is blocked by the arc blocks on the water blocking rod 104. The powerful nozzles 103 can be controlled to spray water by rotating the water blocking rod 104.

[0044] At first, the user starts the two servo motors 6 and the drive motor 93. The output shafts of the two servo motors 6 rotate to drive the camshaft 7 to rotate. Since the cam on the camshaft 7 is elliptical, the camshaft 7 will intermittently hit the movable crushing plate 5 during its rotation.

Example 2

[0045] On the basis of Example 1, Figure 12-16 As shown, it also includes a dust reduction auxiliary component, which is provided on the mounting frame 1, and is used to receive the crushed construction waste. The dust reduction auxiliary component includes a driving wheel 111, and the driving wheel 111 is fixedly connected to the camshaft 7. A driven wheel shaft 112 is rotatably connected to the mounting frame 1, and a belt 113 is wound between the driving wheel 111 and the driven wheel shaft 112. Two top plates 114 are fixedly connected to the driven wheel shaft 112. A collecting frame 115 is connected to the mounting frame 1 by bolts, and the collecting frame 115 is located above the discharge port of the mounting frame 1. Frame 115 is located below the movable crushing plate 5. The collecting frame 115 is used to collect crushed construction waste. A support plate 116 is slidably connected to the collecting frame 115. The support plate 116 closes the bottom of the collecting frame 115. The rotation of the driven wheel shaft 112 will drive the top plate 114 to rotate. During the rotation of the top plate 114, the support plate 116 will be hit, so that the support plate 116 will move away from the collecting frame 115. The construction waste collected in the collecting frame 115 will fall onto the mounting frame 1. Several return springs 117 are connected between the support plate 116 and the mounting frame 1.

[0046] The diameter of the driving wheel 111 is much smaller than the diameter of the driven wheel shaft 112 , and the driving wheel 111 needs to rotate multiple times to drive the driven wheel shaft 112 to rotate one circle.

[0049] Initially, the support plate 116 will close the bottom of the collection frame 115, and the baffle 121 will block the discharge port of the mounting frame 1. The crushed construction waste will fall into the collection frame 115. The dust generated by the falling construction waste will not escape from the collection frame 115. The dust will escape to the top of the collection frame 115 and be covered by the water mist sprayed by the fixed nozzle 102 and the powerful nozzle 103. The rotation of the camshaft 7 will drive the driving wheel 111 to rotate. The rotation of the driving wheel 111 drives the driven wheel shaft 112 to rotate through the belt 113. The rotation of the driven wheel shaft 112 drives the top plate 11 4 rotates, and the top plate 114 will hit the supporting plate 116 during the rotation process, so that the supporting plate 116 will move away from the collecting frame 115, and the reset spring 117 will be compressed. The supporting plate 116 moves so that the construction waste in the collecting frame 115 will fall onto the mounting frame 1, and because the baffle 121 blocks the mounting frame 1, the dust generated by the falling construction waste can only escape in the direction of the nozzle, so that the dust will not escape from the device. After the top plate 114 and the supporting plate 116 are separated, the reset spring 117 resets and drives the supporting plate to reset, so that the bottom of the collecting frame 115 is again The driven wheel shaft 112 is enclosed by the support plate 116, and because the diameter of the driving wheel 111 is much smaller than that of the driven wheel, the driving wheel 111 rotates multiple times before the driven wheel shaft 112 rotates one circle, so that more construction waste is collected in the collection frame 115 before the construction waste is dumped on the mounting frame 1, thereby reducing the number of times the crushed construction waste falls, thereby reducing the generation of dust. After the support plate 116 is reset, the driven wheel shaft 112 continues to rotate, and the driven wheel shaft 112 drives the convex plate 123 to rotate, and the convex part of the convex plate 123 hits the swing rod 122, so that the swing rod 122 The swing of the swing rod 122 will drive the baffle plate 121 to rise. The rising of the baffle plate 121 will open the discharge port of the mounting frame 1, and the user can remove the construction waste dropped on the mounting frame 1. After the raised part of the top plate 114 and the swing rod 122 are separated, the baffle plate 121 will be reset under the action of gravity. The reset of the baffle plate 121 will drive the reset of the swing rod 122, and the discharge port of the mounting frame 1 will be closed.
