DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A construction waste crushing device with a dust reduction mechanism comprises a crushing box 1, both sides of the crushing box 1 are connected with a first exhaust pipe 10 and a second exhaust pipe 11, the inner walls of the first exhaust pipe 10 and the second exhaust pipe 11 are fixedly installed with a mounting frame 12, a fan 29 for discharging dust inside the crushing box 1 is fixedly installed in the mounting frame 12, the inner walls of the first exhaust pipe 10 and the second exhaust pipe 11 are fixedly installed with a first annular pipe 20, a plurality of groups of atomizing nozzles 23 are arranged on the first annular pipe 20, and a filter screen 26 for filtering atomized water after dust reduction is fixedly installed on the inner walls of the first exhaust pipe 10 and the second exhaust pipe 11;

[0025] Two sets of first drive motors 3 are fixedly installed on the side of the crushing box 1, and crushing rollers 5 for crushing construction waste are fixedly connected to the output shafts of the two sets of first drive motors 3 through couplings. A material discharge rack 6 is fixedly connected to the inner wall of the crushing box 1, and the material discharge rack 6 is arranged above the crushing rollers 5. The interior of the crushing box 1 is divided into a crushing chamber 8 and a material discharge chamber 9 by the crushing rollers 5. The first exhaust pipe 10 is connected to the crushing chamber 8, and the second exhaust pipe 11 is connected to the material discharge chamber 9;

[0026] In this embodiment, the top of the crushing box 1 is connected to a lower hopper 2, through which construction waste can be poured into the crushing box 1. When the construction waste is crushed, the dust generated can be purified and discharged through the first exhaust pipe 10. After the construction waste is crushed, the dust generated by the construction waste that falls into the crushing box 1 and is discharged can be purified and discharged through the second exhaust pipe 11.

[0027] A second drive motor 4 is fixedly mounted on the mounting frame 12, a first bevel gear 15 is fixedly mounted on the output shaft of the second drive motor 4, a rotating rod 16 is movably mounted in the mounting frame 12, a second bevel gear 17 is fixedly connected to the rotating rod 16, and the first bevel gear 15 is meshed with the second bevel gear 17;

[0028] The inner wall of the second exhaust pipe 11 is fixedly mounted with a mounting frame 18, and a protective net 19 for dust filtering is arranged in the mounting frame 18. One end of the rotating rod 16 is rotatably mounted in the mounting frame 18, and two groups of brushes 21 are arranged on the rotating rod 16. The two groups of brushes 21 are respectively arranged on both sides of the mounting frame 18, and the two groups of brushes 21 are in contact with the protective net 19;

[0029] It is worth noting that the protective net 19 can filter the dust in the air once and prevent the blocky garbage from falling into the first exhaust pipe 10 and the second exhaust pipe 11.

[0030] The first exhaust pipe 10 and the second exhaust pipe 11 are both fixedly connected with a fixing seat 24, a plug plate 25 is inserted and installed in the fixing seat 24, and a filter screen 26 is arranged in the fixing seat 24;

[0031] Specifically, the plug plate 25 is plugged into the fixing seat 24, so that the filter screen 26 can be easily installed;

[0032] The inner walls of the first exhaust pipe 10 and the second exhaust pipe 11 are both fixedly mounted with a second annular pipe 22, the second annular pipe 22 is connected with a connecting pipe 27, the connecting pipe 27 is provided with a water inlet valve 28, and the second annular pipe 22 is provided with a water spray port;

[0033] It is worth mentioning that when the atomized dust-reducing water in the air is filtered through the filter 26, the dust particles in the atomized dust-reducing water will also be filtered out. The long-term replication and accumulation of dust particles on the filter 26 will block the filter 26 and affect the filtering of the atomized dust-reducing water in the air. Therefore, by opening the water inlet valve 28, the external cleaning water can pass through the connecting pipe 27 and enter the first annular pipe 20, and then be sprayed to the filter 26 through the water spray port, so as to achieve the flushing of the filter 26;

[0034] The bottom of the first exhaust pipe 10 and the bottom of the second exhaust pipe 11 are both connected to a collection box 14 for collecting atomized water, and the side of the collection box 14 is connected to a drain pipe 13, and a drain valve 7 is provided on the drain pipe 13. One end of the first exhaust pipe 10 and the second exhaust pipe 11 are both arranged to be inclined upward;

[0035] It is worth noting that, by setting one end of the first exhaust pipe 10 and the second exhaust pipe 11 to be tilted upward, the atomized dust water filtered by the filter 26 can flow into the collection box 14 along the inner wall of the first exhaust pipe 10 and the second exhaust pipe 11 for collection, and the water collected in the collection box 14 can be discharged by opening the drain valve 7 on the drain pipe 13;

[0036] When in use, the garbage is poured into the crushing box 1 through the lower hopper 2, and the first drive motor 3 is operated. The first drive motor 3 rotates to drive the crushing roller 5 to rotate, so that the crushing roller 5 can crush the garbage. The crushed garbage can fall into the lower material cavity 9 and then be discharged. When the garbage is poured into the crushing box 1, the fan 29 works. The fan 29 can suck the outside air into the crushing box 1 and blow the dusty air in the crushing box 1 out of the crushing box 1.

[0037] When the air with dust passes through the protective net 19, the dust in the air can be filtered once through the protective net 19. When the air filtered once through the protective net 19 passes through the first annular tube 20, the first annular tube 20 cooperates with the atomizing nozzle 23, so that the atomized dust-reducing water can be sprayed out, so that the atomized dust-reducing water can follow the dust-carrying air to be discharged from the crushing box 1, and the dust in the discharged air is reduced. The atomized water after dust reduction contains a large amount of dust particles. The air with the atomized dust-reducing water can be filtered through the filter net 26, and the content of the atomized dust-reducing water in the air can be reduced to remove or reduce the dust therein, thereby preventing pollution to the surrounding environment. The filtered air can be discharged through the first exhaust pipe 10 and the second exhaust pipe 11;

[0038] The atomized dust-reducing water filtered by the filter 26 may fall on the inner walls of the first exhaust pipe 10 and the second exhaust pipe 11 , and then flow into the collection box 14 along the inner walls of the first exhaust pipe 10 and the second exhaust pipe 11 to be collected.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
