Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment, in particular to a construction waste rapid treatment device. Background Art

[0002] Construction waste refers to waste generated during construction, decoration, demolition, etc., including various materials such as concrete, bricks, wood, metal, glass, plastic, etc. In current life, after construction waste is generated, in order to improve environmental quality and recycle resources, it is necessary to crush the construction waste, but a large amount of dust is generated in the process of crushing construction waste.

[0003] The Chinese patent "A construction waste crushing and processing equipment" authorization announcement number "CN219252726U" is equipped with a water tank, a water pump, a water pipe, a water outlet pipe, and a nozzle. The water pump is started, and the water pump drives the water outlet pipe to extract water from the water tank. The water pump discharges water into the water outlet pipe and sprays it through the nozzle, so that it can reduce the dust generated during crushing.

[0004] Although the above scheme can achieve the effect of dust reduction, since mud will be produced when water and dust are mixed, when water is sprayed into the crushing box to reduce dust, the produced mud will adhere to the crushing roller, resulting in a decrease in the friction between the crushing roller and the material, thereby affecting the crushing effect of the crushing roller.

[0005] Therefore, a construction waste rapid processing device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a rapid processing equipment for construction waste in order to solve the above-mentioned problem, which improves the problem that mud will be produced after water and dust are mixed. When water is sprayed into the crushing box to reduce dust, the generated mud will adhere to the crushing roller, resulting in a decrease in the friction between the crushing roller and the material, thereby affecting the crushing effect of the crushing roller.

DETAILED DESCRIPTION

[0024] 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.

[0025] When implementing: Figure 1-5 As shown, a construction waste rapid processing equipment comprises: a base 1, a crushing box 2 is fixedly connected to the top of the base 1, and two crushing rollers 3 are rotatably connected to the inner wall of the crushing box 2; a dust reduction mechanism 4 is arranged on one side of the crushing box 2 for reducing dust when the construction waste is crushed; wherein the dust reduction mechanism 4 comprises a processing box 401 fixedly connected to the top of the base 1, a fan 402 is installed on the top of the processing box 401, a three-way pipe 403 is arranged inside the processing box 401, a first filter plate 405 is fixedly connected to the upper end of the inner wall of the processing box 401, and the other two ends of the three-way pipe 403 successively penetrate the first filter plate 405 and the processing box 401 to the inside of the crushing box 2, a water pump 404 is arranged at the front end of the processing box 401, and a dust reduction component 406 is arranged inside the processing box 401. The other two ends of the three-way pipe 403 are horn-shaped.

[0026] One end of the two crushing rollers 3 passes through the crushing box 2 and is fixedly connected to gears. The two gears are meshed and connected. A motor is arranged on the other side of the crushing box 2. The other end of one of the gears is fixedly connected to the output shaft of the motor. Since the two gears are meshed, when the motor drives one of the gears to rotate, it will drive the other gear to rotate in the opposite direction.

[0027] A feed port is provided at the top of the crushing box 2. When the construction waste needs to be crushed, the construction waste is put into the crushing box 2 through the feed port. The motor is manually turned on to drive the two gears to rotate in opposite directions, so that the two crushing rollers 3 rotate in opposite directions to crush the construction waste. A discharge port is provided at the bottom end of the crushing box 2, and a receiving box is provided at the bottom end of the discharge port. The crushed construction waste will enter the receiving box through the discharge port. When the construction waste is crushed, the dust reduction mechanism 4 is driven to operate to process the dust generated during the crushing.

[0028] The air inlet end of the fan 402 is arranged above the first filter plate 405. When processing the dust during crushing, the fan 402 is manually started. When the fan 402 is started, the air in the processing box 401 will be discharged, so that a negative pressure will be formed in the processing box 401. At this time, the three-way pipe 403 will adsorb the dust during crushing, and the three-way pipe 403 will suck the dust into the interior of the processing box 401. The first filter plate 405 blocks the sucked dust to prevent the dust from being discharged through the fan 402. At the same time, the water pump 404 is manually started to drive the dust reduction component 406 to operate.

[0029] It should be noted that the motor, fan 402 and water pump 404 in the above description are all relatively mature devices in existing technology, and the specific models can be selected according to actual needs.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the dust suppression assembly 406 includes a mounting pipe 4062 fixedly connected to the upper end of the inner wall of the treatment box 401, a connecting pipe 4061 fixedly connected to the water outlet of the water pump 404, the other end of the connecting pipe 4061 penetrates into the interior of the treatment box 401 and communicates with the mounting pipe 4062, the surface of the mounting pipe 4062 is fixedly connected to circular pipes 4063 distributed in equal rows, both sides of the surface of the circular pipes 4063 are fixedly connected to nozzles 4064 distributed in equal rows, and the inner wall of the treatment box 401 is fixedly connected to a fixing plate 4065. The nozzles 4064 on the surfaces of two adjacent circular pipes 4063 are staggered.

[0031] The bottom end of the fixed plate 4065 and the bottom wall of the treatment box 401 are filled with a water solution. One end of the three-way pipe 403 is located above the fixed plate 4065. When the dust generated during crushing is sucked into the treatment box 401, the dust will be placed between the fixed plate 4065 and the first filter plate 405. The water inlet of the water pump 404 is connected to the treatment box 401. When the water pump 404 is started, the water pump 404 will suck out the water solution in the treatment box 401 and enter the installation pipe 4062 through the connecting pipe 4061. The installation pipe 4062 is set at the first filter plate 405. 05, when the aqueous solution enters the installation tube 4062, it will enter multiple circular tubes 4063 at the same time, and the water spraying direction of the nozzle 4064 is set to spray water in the horizontal direction, and the water spraying directions of the two adjacent groups of nozzles 4064 are opposite. When the aqueous solution enters the circular tube 4063, the multiple nozzles 4064 corresponding to the circular tube 4063 will spray water horizontally at the same time. At this time, the dust between the fixed plate 4065 and the first filter plate 405 will merge with the aqueous solution sprayed by the nozzle 4064, and the dust after merging with the aqueous solution will fall on the fixed plate 4065.

[0032] like Figure 3 , Figure 4 and Figure 5As shown, a fixed frame 4066 is fixedly connected to one side of the processing box 401, and a second filter plate 4067 is installed on the inner wall of the fixed frame 4066. An angle is formed between the bottom end of the fixed plate 4065 and the horizontal plane, and the lower end of the fixed plate 4065 penetrates into the interior of the fixed frame 4066.

[0033] When the dust after merging with the aqueous solution falls on the fixed plate 4065, under the action of the aqueous solution, the fused dust will slide along the inclined surface of the fixed plate 4065 to the second filter plate 4067 in the fixed frame 4066 of the crushing box 2. At this time, the second filter plate 4067 filters the fallen aqueous solution and the fused dust, and the dust after merging with the aqueous solution will be retained on the second filter plate 4067, and part of the aqueous solution will fall under the second filter plate 4067 after filtration.

[0034] A sealing plate is provided on the other side of the fixed frame 4066, and the sealing plate is connected to the fixed frame 4066 by bolts. One side of the second filter plate 4067 is fixedly connected to the sealing plate. When the second filter plate 4067 needs to be cleaned, the threaded connection between the sealing plate and the fixed frame 4066 is released, and the sealing plate is pulled outward to remove the second filter plate 4067 for cleaning.

[0035] like Figure 4 and Figure 5 As shown, the bottom end of the fixed frame 4066 is fixedly connected with a return pipe 4068, the other end of the return pipe 4068 penetrates into the interior of the processing box 401, and a one-way valve 4069 is provided on the surface of the return pipe 4068. The bottom end of the fixed frame 4066 is funnel-shaped.

[0036] The aqueous solution falling under the second filter plate 4067 will re-enter the treatment box 401 through the return pipe 4068. The other end of the return pipe 4068 is arranged under the fixed plate 4065. Under the action of the one-way valve 4069, the return pipe 4068 is a one-way water outlet pipe.

[0037] like Figure 4 and Figure 5 As shown, an angle is formed between the bottom end of the second filter plate 4067 and the horizontal plane. When the fused dust slides along the inclined surface of the fixing plate 4065 to the second filter plate 4067, the dust fused with water will slide to the lower end of the second filter plate 4067 under the action of the inclined surface of the second filter plate 4067.

[0038] When the utility model is in use, when crushing construction waste, the construction waste is put into the crushing box 2, and the motor is manually started to drive the two crushing rollers 3 to rotate in opposite directions to crush the construction waste. At the same time, when processing the dust generated during the crushing, the fan 402 in the dust reduction mechanism 4 is manually started. When the fan 402 is started, the air in the processing box 401 is discharged, so that a negative pressure is formed in the processing box 401. At this time, the three-way pipe 403 will suck the dust generated during the crushing between the fixed plate 4065 and the first filter plate 405 in the processing box 401, and the water pump 404 is manually started to suck the aqueous solution in the processing box 401 into the connecting pipe 4061, and the water is discharged through the installation pipe. 4062 enters multiple circular tubes 4063 at the same time. At this time, multiple nozzles 4064 corresponding to the circular tubes 4063 will simultaneously spray water horizontally to merge with the dust. The dust after merging with the aqueous solution will fall onto the fixed plate 4065 and slide along the inclined surface of the fixed plate 4065 to the second filter plate 4067 in the fixed frame 4066 of the crushing box 2. At this time, the second filter plate 4067 filters the fallen aqueous solution and the fused dust. The dust after merging with the aqueous solution will be retained on the second filter plate 4067. Part of the aqueous solution will fall under the second filter plate 4067 after filtration and enter the processing box 401 again through the reflux pipe 4068, completing the centralized collection of dust.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
