Technical Field

[0001] This utility model relates to the field of construction waste recycling, and in particular to a construction waste crushing device with dust removal function. Background Technology

[0002] Construction waste refers to waste generated during construction, demolition, and decoration activities, such as waste concrete, bricks, metals, and plastics. Waste waste has the characteristics of recycling. However, when recycling construction waste, it is usually necessary to use crushing equipment to pre-crush the construction waste to facilitate subsequent processing. As shown in the dust removal device for construction waste treatment disclosed on the China Patent Network (publication announcement number CN221714400U), this type of device uses a first crushing component and a second crushing chamber to crush the construction waste during the crushing process. At the same time, the two sets of nozzles can reduce dust at both ends of the path after the construction waste enters the box, thus preventing dust from escaping.

[0003] However, existing construction waste crushing devices, as described in the aforementioned patents and in the current market, still have some shortcomings: While these devices use nozzles at their inlets and outlets to spray and suppress dust, the fixed assembly of these nozzles limits their atomization range and dust suppression capabilities, often failing to effectively address the dust generated during the crushing process. Therefore, those skilled in the art have provided construction waste crushing devices with dust removal functions to solve the problems mentioned in the background section. Utility Model Content

[0014] This utility model provides a construction waste crushing device with dust removal function, which has the following advantages compared with the prior art:

[0015] 1. The construction waste crushing device designed in this paper uses two sets of crushing rollers to perform a stepped crushing process on construction waste. During the crushing and feeding process, the two sets of crushing rollers are used as the driving source. On the one hand, the reciprocating oscillating structure drives the atomizing nozzle to reciprocate and oscillate, spraying water mist into the dust settling box in a dynamic dispersion manner. This atomizes and settles the dust generated during feeding and crushing, achieving a good atomization dust removal effect. On the other hand, the transmission belt drives the spiral auger to rotate, quantitatively pushing and unloading the crushed construction waste in a spiral unloading manner. It also has a good sealing effect, making the dust diffusion range smaller during the unloading of construction waste.

[0016] 2. The construction waste crushing device designed in this paper has a buffer structure during the crushing and feeding process of construction waste. This buffer structure helps to reduce dust dispersion caused by the falling and collision of construction waste during feeding. Furthermore, the buffer structure after unloading also has a good isolation effect, which can reduce dust dispersion. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution for a construction waste crushing device with dust removal function: The construction waste crushing device with dust removal function includes a crushing box 1. Two sets of first crushing rollers 18 are provided on the upper inner side of the crushing box 1. The two sets of first crushing rollers 18 rotate in opposite directions via two sets of meshing first gears 10. Two sets of second crushing rollers 19 are provided on the lower inner side of the crushing box 1. The two sets of second crushing rollers 19 rotate in opposite directions via two sets of meshing second gears 11. A motor 7 is provided on one side of the crushing box 1. A first transmission belt 8 connects the motor 7 and the first crushing rollers 18, and the first crushing rollers 18 and the second crushing rollers 19 are connected by a... The device has a second transmission belt 9. During the crushing process of construction waste, the construction waste is fed into the crushing box 1 through the feeding hopper 3. Then, the motor 7 is controlled to work, driving the first transmission belt 8 to rotate, which in turn drives one set of first crushing rollers 18 to rotate. The meshing of two sets of first gears 10 drives the two sets of first crushing rollers 18 to rotate, thus performing a preliminary crushing process on the construction waste. At the same time as the first crushing rollers 18 rotate, the second transmission belt 9 drives one set of second crushing rollers 19 to rotate. The meshing of two sets of second gears 11 drives the two sets of second crushing rollers 19 to rotate, thus performing a secondary crushing process on the construction waste.

[0026] Furthermore, a dust collection box 2 is provided above the crushing box 1. Two sets of material-retarding structures 22 are provided on the lower inner side of the dust collection box 2. Each material-retarding structure 22 includes a side support frame 221, a material-retarding plate 222 at the top of the side support frame 221, and lifting guide rails 224 on both sides of the side support frame 221. A lifting slide 225 is provided along the lifting guide rails 224, and a support arm 223 connects the lifting slide 225 to the material-retarding plate 222. A spring seat 226 supporting the lifting slide 225 is provided at the bottom of the side support frame 221. During the feeding of construction waste, the construction waste falls onto the buffer plate 222 as it falls. At this time, the buffer plate 222, supported by the elasticity of the support arm 223 and the spring seat 226, has an opening and closing characteristic, which buffers the construction waste and makes the feeding of construction waste more gentle, thereby reducing the dust dispersion caused by falling collisions during the feeding process. In addition, after unloading, the buffer plate 222 resets under the action of elasticity, reducing its unloading opening and providing a better isolation effect, which can reduce the dispersion of dust.

[0027] In addition, two sets of water supply pipes 20 are provided on the upper inner side of the dust settling box 2. Multiple sets of atomizing nozzles 21 are arranged along the pipe direction of each water supply pipe 20. A water supply valve is provided at one end of each water supply pipe 20. A reciprocating oscillating structure exists between the water supply pipe 20 and the first crushing roller 18. This reciprocating oscillating structure includes an oscillating wheel 16 at one end of the water supply pipe 20 and a third gear 12 at one end of the first crushing roller 18. A fourth gear 13 meshes with one side of the third gear 12. A first support arm 14 is provided on the central shaft of the fourth gear 13, and a second support arm 15 connected to the oscillating wheel 16 is provided at the top of the arm of the first support arm 14. During the crushing and feeding of construction waste, the first crushing roller 18 rotates simultaneously, driving the third gear 12 to rotate synchronously. The meshing of the third gear 12 and the fourth gear 13 drives the first support arm 14 to rotate. Then, the pull of the second support arm 15 generates a driving force to drive the sway wheel 16 to sway back and forth, giving the water supply pipe 20 the characteristic of swaying back and forth. Then, through an external water pump, clean water is pumped into the water supply pipe 20 through the water supply valve, so that the clean water is atomized and sprayed out through the atomizing nozzle 21. In a dynamic spraying manner, it is sprayed to various positions in the dust settling box 2 to adsorb and settle the construction dust.

[0028] It should be noted that a discharge hopper 4 is provided below the crushing box 1, and a discharge cylinder 5 is provided at the conical bottom of the discharge hopper 4. A spiral auger 23 is provided inside the discharge cylinder 5, and a third transmission belt 17 is provided between the spiral auger 23 and the second crushing roller 19. The spiral auger 23 is divided by a center line, and the propeller blades on both sides of the center line are arranged in opposite directions. During the crushing of construction waste, the construction waste after double crushing is collected into the discharge cylinder 5 through the discharge hopper 4. At this time, while the second crushing roller 19 is rotating, the spiral auger 23 is driven to rotate synchronously through the third transmission belt 17, and the construction waste is conveyed to both ends of the discharge cylinder 5 in a spiral pushing manner. The crushed construction waste is discharged quantitatively through the discharge ports 6 located at both ends of the discharge cylinder 5. The discharge has a good sealing effect, so that the construction waste can only be discharged through the discharge ports 6, and the dust diffusion range after crushing is smaller.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
