[0028] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0029] The embodiment of the present application discloses a construction waste crusher with a dust removal device.

[0030] Reference Figure 1 and Figure 2 A construction waste crusher with a dust removal device comprises a crusher 1. The crusher 1 is used to connect a dust removal port 21 of a dust removal pipe 2. An exhaust device 22 and a water spray hole 23 are arranged in the dust removal pipe 2. The dust inside the crusher 1 is discharged into the dust removal pipe 2 through the exhaust device 22. Water is sprayed into the dust removal pipe 2 through the water spray hole 23 to remove the dust, thereby achieving effective removal of the dust generated by the crusher 1.

[0031] Reference Figure 2A feeding port 11 is provided at the upper end of the crusher 1, and an end cover 111 is sleeved on the feeding port 11. When feeding the crusher 1, the end cover 111 of the feeding port 11 is removed, and the construction waste is fed into the crusher 1 through the feeding port 11. After the feeding is completed, the end cover 111 is put back on the feeding port 11, and the feeding port 11 is blocked by the end cover 111 to prevent dust from being discharged through the feeding port 11. A sealing groove is provided on the inner wall of the end cover 111, and the sealing groove is an annular groove provided along the inner wall of the end cover 111. A sealing gasket 112 is installed in the sealing groove. When the end cover 111 is sleeved on the feeding port 11, the sealing gasket 112 is tightly attached to the outer wall of the feeding port 11, and the gap between the feeding port 11 and the end cover 111 is further reduced by the sealing gasket 112.

[0032] Reference Figure 2 The crushing roller 14 is rotatably connected to the inner wall of the crusher 1. The crusher 1 is provided with a driving device 13 for driving the crushing roller 14 to rotate. In this embodiment, a motor is preferably used as the driving device 13 of the crushing roller 14. In this embodiment, a plurality of cutting blades are installed on the outer side of the crushing roller 14, and the construction waste is cut by the high-speed rotation of the blades. The motor crushing roller 14 crushes the input construction waste, and the crushed construction waste enters the bottom of the crusher 1.

[0033] Reference Figure 2 The crusher 1 is provided with a dust removal port 21 and is connected with a dust removal pipe 2. In this embodiment, the dust removal port 21 and the dust removal pipe 2 are installed at the upper part of the crusher 1. An exhaust device 22 is installed in the dust removal pipe 2. In this embodiment, an exhaust fan is used as the exhaust device 22. The dust and air inside the crusher 1 are discharged into the dust removal pipe 2 through the exhaust fan, and the exhaust fan forces the gas to flow, thereby accelerating the discharge of dust and air inside the crusher 1.

[0034] Reference Figure 2 The crusher 1 is provided with an air inlet 12. When the exhaust device 22 exhausts the crusher 1, internal negative pressure may occur. The additional air inlet 12 can effectively increase the air intake inside the crusher 1, effectively improve the air convection inside the crusher 1, and effectively improve the exhaust efficiency of the exhaust device 22, so that the dust inside the crusher 1 can be discharged through the dust removal pipe 2 as much as possible. A filter 121 is provided at the air inlet 12. The filter 121 can effectively prevent the dust inside the crusher 1 from being discharged from the machine through the air inlet 12, and effectively block the internal dust.

[0035] Reference Figure 2The dust collecting pipe 2 is provided with an extension part 26, and the extension part 26 is located at the end of the dust collecting pipe 2. The diameter of the dust collecting pipe 2 of the extension part 26 is much larger than the front half of the dust collecting pipe 2 connected to the crusher 1, and an extension chamber 261 is formed in the extension part 26. When the dust and air mixture extracted from the crusher 1 through the exhaust device 22 in front enters the extension chamber 261, the diameter of the dust collecting pipe 2 suddenly increases. The pipe diameter increases and the exhaust volume of the exhaust device 22 remains stable, which satisfies the conditions that the fluid flow rate is constant and the pipe diameter increases, and the fluid flow rate will decrease. Eventually, the air mixed with dust will reduce its speed and fill the entire extension chamber 261. The reduced dust speed makes it easier to carry out subsequent processing work.

[0036] Reference Figure 2 A plurality of water spray holes 23 are provided in the circumferential direction of the wall of the dust removal pipe 2, and the water spray holes 23 are connected to a water supply pipe 24. The water spray holes 23 are provided in the wall of the expansion part 26, and water is supplied to the water spray holes 23 through the water supply pipe 24. When the machine starts to be used, the water spray holes 23 spray water into the dust removal pipe 2. Since water has a good adsorption effect on dust, the dust in the dust removal pipe 2 can be adsorbed and settled by spraying water into the expansion chamber 261, and the air mixed with dust discharged from the crusher 1 through the exhaust device 22 is effectively purified. Since the flow rate of the air mixed with dust entering the expansion chamber 261 is reduced, the purification effect of the water spray on the dust is further improved.

[0037] Reference Figure 2 , an atomizing nozzle 25 is provided at the water spray hole 23. The atomizing nozzle 25 points to the inside of the dust removal pipe 2. When the water supply pipe 24 supplies water to the water spray hole 23, the water flows through the atomizing nozzle 25 to spray water into the dust removal pipe 2. Since the water flows through the atomizing nozzle 25 for atomization, the water coverage area is effectively expanded, and the atomized water flows have a larger contact range with the dust, resulting in the atomized water flows to better adsorb and settle the dust. Further enhance the removal effect of the dust.

[0038] Reference Figure 2 A wastewater collection bucket 3 is installed under the expansion chamber 261. Since the water spraying device cannot completely purify the air from the crusher 1, and the water mixed with dust also needs to be received, a wastewater collection bucket 3 is installed at the end of the dust removal pipe 2 to collect the discharged wastewater. After filtering, the collected wastewater can be further recycled for construction waste in the wastewater.

[0039] Reference Figure 2, the wastewater collection bucket 3 is detachably connected to the end of the dust removal pipe 2. In this embodiment, a slot and a snap ring are used to realize a detachable connection of the wastewater bucket. The snap ring is provided with the end of the dust removal pipe 2, and the slot is provided on the upper end face of the wastewater bucket and is adapted to the snap ring. When the wastewater collection bucket 3 is installed under the dust removal pipe 2, the snap ring at the end of the dust removal pipe 2 is embedded in the slot on the upper end face of the wastewater collection bucket 3. Alternatively, an exhaust hole can be provided around the upper part of the wastewater collection bucket 3, and the exhaust hole allows the device to better discharge the air that has been dusted.

[0040] The implementation principle of a construction waste crusher with a dust removal device in the embodiment of the present application is as follows: the dust in the crusher 1 is discharged into the dust removal pipe 2 through the exhaust device 22, and the dust flow rate is slowed down and fills the entire expansion cavity through the dust removal pipe 2 with a sudden change in diameter, and the water flow is atomized by the atomizing nozzle 25 to effectively expand the contact area between water and dust, thereby effectively treating the dust.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
