Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, and more specifically, to a construction waste treatment device. Background Technology

[0002] Sand crushers, commonly used for processing construction waste, can effectively break down cement bricks, tiles, and other construction waste into recycled aggregates of the required particle size. These recycled aggregates can be used to produce recycled concrete, recycled mortar, and other building materials, as well as for paving road bases, and for making recycled bricks and blocks.

[0003] Existing sand making machines often face serious dust pollution problems when processing construction waste. When waste is fed into the hopper and processed material is discharged from the discharge hopper, a large amount of dust is sprayed out. This dust quickly spreads into the air, which not only reduces the air quality of the working environment, but also pollutes the surrounding environment. Utility Model Content

[0004] This utility model proposes a construction waste treatment device, which solves the technical problem that existing sand making machines spray out a large amount of dust when processing construction waste. This dust quickly spreads into the air, which not only reduces the air quality of the working environment, but also pollutes the surrounding environment.

[0005] This utility model proposes a construction waste treatment equipment, including a sand making machine, an exhaust fan, a dust removal component, and a conveying component;

[0006] The sand making machine has a discharge port at the bottom;

[0007] The conveying assembly includes a conveyor located below the discharge port of the sand making machine, and a dustproof plate fixedly covering the top of the conveyor. The top of the dustproof plate has a feeding hole that connects with the discharge port of the sand making machine, and the bottom of the discharge port is sealed to the periphery of the feeding hole.

[0008] The dust removal assembly includes a dust removal box with a top opening. The top of the dust removal box has an installation groove. A retractable frame is slidably installed in the installation groove. The outer wall of the frame has a gripping hole. Multiple dust removal components are arranged in a stepped manner at vertical intervals inside the frame. A guide groove is formed between adjacent dust removal components.

[0009] The exhaust fan is fixedly installed on the side wall of the dust collector, and the air inlet of the exhaust fan penetrates through the side wall of the dust collector and communicates with the inside of the dust collector.

[0010] Preferably, the dust removal component includes a dust collector plate and a dust removal net vertically installed at its end.

[0011] Preferably, the top of the dust removal net is curved to form an arc-shaped bend.

[0013] Preferably, a support frame is fixedly installed at the bottom of the sand making machine, and the conveyor, dust collector and exhaust fan are respectively fixedly installed on the support frame.

[0014] Preferably, a water supply pipe is fixedly installed on the top of the dust collection box, and multiple branch pipes are fixedly connected to the outer wall of the water supply pipe. Multiple atomizing nozzles are fixedly connected to the outer wall of each branch pipe, and the atomizing nozzles of the atomizing nozzles extend to the inner wall of the dust collection box.

[0015] Preferably, a sealing plate is hinged at the port of the dust collector, and a sealing strip that fits into the dust collector is fixedly installed on the outer wall of the sealing plate.

[0016] Preferably, a partition is fixedly connected to the inner wall of the dust collection box, and the top of the partition is in contact with the bottom of the frame.

[0019] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0020] 1. During operation, the exhaust fan generates suction to expel the air from the dust collection box, accelerating the airflow in the space between the dust collection box, the sand making machine, the conveyor, and the dustproof plate. This prevents dust from being discharged through the sand making machine's feed inlet and discharge outlet and spreading into the air, thus protecting the working environment and the surrounding environment.

[0021] 2. By setting guide channels between adjacent dust removal components, the airflow speed inside the dust removal box can be increased, and the dust removal components can quickly filter dust.

[0022] 3. When dust enters the dust collection box, atomized water is sprayed into the dust collection box through the atomizing nozzle to come into contact with the dust. Combined with the dust collection components, this can effectively improve the dust collection effect.

[0023] 4. By holding the grip hole, the frame can be pulled out of the dust collection box, making it easy for operators to clean the dust on the dust collection screen and dust support plate. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1-5 As shown, a construction waste treatment device includes a sand making machine 2, an exhaust fan 7, a dust removal component and a conveying component, with a discharge port at the bottom of the sand making machine 2;

[0033] The conveying assembly includes a conveyor 3 located below the discharge port of the sand making machine 2, and a dustproof plate 4 fixedly covering the conveyor 3. The top of the dustproof plate 4 has a feeding hole 5 that connects with the discharge port of the sand making machine 2, and the bottom of the discharge port is sealed to the periphery of the feeding hole 5.

[0034] The dust removal assembly includes a dust removal box 6 with a top opening, a mounting groove 8 on the top of the dust removal box 6, a pull-out frame 9 slidably disposed in the mounting groove 8, a gripping hole 10 on the outer side wall of the frame 9, and multiple dust removal components 11 arranged in a stepped manner along the vertical spacing inside the frame 9, with a guide channel 12 formed between adjacent dust removal components 11.

[0035] The exhaust fan 7 is fixedly installed on the side wall of the dust collector 6, and the air inlet of the exhaust fan 7 penetrates through the side wall of the dust collector 6 and communicates with the interior of the dust collector 6.

[0036] In the above structure, during the operation of the sand making machine 2, the exhaust fan 7 generates suction to expel the air in the dust collection box 6, accelerate the air flow in the space between the dust collection box 6, the sand making machine 2, the conveyor 3 and the dustproof plate 4, and prevent dust from being discharged and diffused into the air through the feed port and discharge hole of the sand making machine 2, thus protecting the working environment and the surrounding environment.

[0037] like Figure 6 As shown, the dust removal component 11 includes a dust support plate 113 and a dust removal net 111 vertically installed at its end. The vertically installed dust support plate 113 can prevent dust falling off the dust removal net 111 from falling into the dust removal box 6.

[0038] like Figure 6 As shown, the top of the dust collection screen 111 is curved to form an arc-shaped bend 112, and the top of the dust collection plate 113 has an S-shaped curved surface 114. The dust is filtered by the dust collection screen 111, and the accumulated dust falls into the groove of the curved surface 114 on the top of the dust collection plate 113, thereby collecting the dust; the design of the curved surface 114 and the bend 112 can reduce the resistance of airflow inside the dust collection box 6.

[0039] like Figure 1 As shown, a support frame 1 is fixedly installed at the bottom of the sand making machine 2, and the conveyor 3, dust collector 6 and exhaust fan 7 are respectively fixedly installed on the support frame 1.

[0040] like Figure 3 As shown, a water supply pipe 22 is fixedly installed on the top of the dust collection box 6. Multiple branch pipes 23 are fixedly connected to the outer wall of the water supply pipe 22, and multiple atomizing nozzles 24 are fixedly connected to the outer wall of each branch pipe 23. The atomizing nozzles of the atomizing nozzles 24 extend to the inner wall of the dust collection box 6. When dust enters the dust collection box 6, atomized water is sprayed into the dust collection box 6 through the atomizing nozzles 24 to contact the dust, thereby achieving a dust suppression effect.

[0041] like Figure 3As shown, a sealing plate 25 is hinged at the port of the dust collector 6, and a sealing strip that fits into the dust collector 6 is fixedly installed on the outer wall of the sealing plate 25. During the operation of the exhaust fan 7, the sealing plate 25 will tightly abut against the port of the dust collector 6 under the action of suction, achieving a sealing effect and preventing dust inside the dust collector 6 from spreading outward.

[0042] like Figure 5 As shown, a partition 13 is fixedly connected to the inner wall of the dust collection box 6, and the top of the partition 13 contacts the bottom of the frame 9.

[0043] like Figure 3 As shown, a water collection tank 14 is fixedly installed on the inner wall of the dust collection box 6, and the water collection tank 14 is located below the atomizing nozzle 24.

[0044] like Figure 5 As shown, the inner wall of the water collection tank 14 is equipped with a filter screen 21. Rotating shafts 20 are fixedly connected to both sides of the filter screen 21, and the rotating shafts 20 are rotatably connected to the dust collection box 6. A fixing plate 15 is fixedly connected to the top of the filter screen 21, and a fixing block 16 is fixedly connected to the top of the filter screen 21. A sliding rod 17 is fixedly connected between the fixing plate 15 and the fixing block 16. A cleaning brush 18 is in frictional contact with the top of the filter screen 21. The sliding rod 17 passes through the cleaning brush 18 and is slidably connected to it. A pull rod 19 is fixedly connected to the outer wall of the cleaning brush 18. After the exhaust fan 7 stops, by flipping the sealing plate 25, the pull rod 19 is pulled outwards, causing the cleaning brush 18 to move on top of the filter screen 21, thereby cleaning the dust clogging the filter screen 21. Flipping the filter screen 21 upwards around the rotating shaft 20 opens the top of the water collection tank 14, facilitating cleaning of the inside of the water collection tank 14 by the operator. Impurities in the atomized water are filtered through the filter screen 21. The filtered water flows into the water collection tank 14 and is discharged through the drain outlet on the side wall of the dust removal box 6.

[0045] Working principle: During operation, the exhaust fan 7 of the sand making machine 2 generates suction to expel the air in the dust collection box 6, accelerate the air flow in the space between the dust collection box 6, the sand making machine 2, the conveyor 3 and the dustproof plate 4, and prevent dust from being discharged through the feed port and discharge hole of the sand making machine 2.

[0046] When dust enters the dust collection box 6, atomized water is sprayed into the dust collection box 6 through the atomizing nozzle 24 to come into contact with the dust and suppress it.

[0047] Impurities in the atomized water are filtered through the filter screen 21. The filtered water flows into the water collection tank 14 and is discharged through the drain outlet on the side wall of the dust removal box 6.

[0048] After the exhaust fan 7 stops, the sealing plate 25 is flipped over and the pull rod 19 is pulled outward to drive the cleaning brush 18 to move on top of the filter screen 21, thereby cleaning the dust that is blocked on the filter screen 21.

[0049] Flipping the filter screen 21 upwards with the pivot 20 as the center allows the top of the water collection tank 14 to open.

[0050] By grasping the holding hole 10, the frame 9 is pulled out from the dust collection box 6.

[0051] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
