Description

Technical Field

[0001] This utility model relates to the field of waste crushing technology, specifically an environmentally friendly construction waste recycling and processing device. Background Technology

[0002] During construction, some large-volume waste materials are generated. When recycling these waste materials, it is necessary to first reduce their volume, which means crushing them using a crushing device.

[0003] Because a large amount of dust is inevitably generated during the crushing process of construction waste, the dust will be released along with the crushed construction waste when it is discharged, posing a safety hazard to the health of workers.

[0004] Although dust suppression can be achieved by installing spray heads inside the crushing equipment, the spraying effect is not good. This is mainly because the internal space of the crushing equipment is large, and the spraying range of the spray heads is limited, causing some dust to drift into areas that the spray heads cannot reach, thus resulting in poor spraying effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an environmentally friendly construction waste recycling and processing device.

[0006] To solve the aforementioned technical problems, this utility model provides the following technical solution:

[0007] An environmentally friendly construction waste recycling and processing device includes:

[0008] A closed internal crushing chamber with a discharge port at the lower end;

[0009] A dust cover with an open bottom is installed inside the crushing chamber;

[0010] A feeding hopper located at the top of the crushing chamber and communicating with the interior of the dust cover;

[0011] A crushing component located inside the dust cover and used for crushing waste material fed into the crushing chamber from the feeding hopper;

[0012] Two floating seats located inside the crushing chamber and capable of sliding freely up and down are respectively engaged in the movable space enclosed by the sides of the dust cover and the inner wall of the crushing chamber. The two floating seats are driven to move vertically by a lifting component. The two floating seats and the lower space inside the crushing chamber form a spray dust suppression chamber.

[0013] A closure component for sealing the gap between the two floating seats after they have moved downwards to below the dust cover.

[0014] Preferably, the crushing component includes two crushing toothed rollers that are horizontally rotatably connected to the crushing chamber. The two crushing toothed rollers are located inside the dust cover, and they rotate at the same speed but in opposite directions.

[0015] Preferably, the feeding bins are arranged in a series of constricted openings from top to bottom.

[0016] Preferably, the lifting component includes two lifting cylinders symmetrically arranged on the crushing chamber along the center line of the crushing chamber, the cylinder rods of the lifting cylinders passing through the crushing chamber and connected to the floating seat.

[0017] Preferably, the closure includes:

[0018] A translation cylinder is horizontally installed in the mounting cavity inside the floating seat, and the two translation cylinders in the floating seat are symmetrically arranged along the center line of the crushing chamber;

[0019] The baffles, which are connected to the cylinder rods of the two translation cylinders and movably connected within the mounting cavity, can bring the two baffles closer together until their ends abut each other when the cylinder rods of the two translation cylinders are extended, thereby reducing the gap between the opposite ends of the two floating seats.

[0020] Preferably, a plurality of spray heads extending into the lower end of the crushing chamber are provided on the outer wall of the chamber, and the spray heads are located in the dust suppression spray chamber.

[0021] Preferably, the bottom of the crushing chamber is fixedly connected to a hollow water collection chamber, and the top wall of the water collection chamber is provided with a plurality of filter holes that penetrate the bottom of the crushing chamber and communicate with the spray dust suppression chamber.

[0022] Preferably, the outer wall of the water collection tank is provided with a water outlet that communicates with the interior of the water collection tank.

[0023] Preferably, a drive shaft is rotatably connected to the lower end of the crushing chamber, a spiral conveyor plate is fixedly mounted on the drive shaft, and the drive shaft is driven to rotate by a motor installed on the outer wall of the crushing chamber. The axial direction of the drive shaft is coaxial with the discharge port.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] By setting two floating seats, after crushing, the two floating seats move downwards to the bottom of the dust cover, and then the gap between the two floating seats is sealed by the sealing component. Then the floating seats continue to move downwards. In this way, the dust volume in the spray dust suppression chamber formed by the floating seats and the lower space of the crushing layer can be compressed, making it difficult for the dust to escape. This ensures that there are no blind spots in the spray area and improves the spray dust removal effect.

[0026] By setting up a baffle, the two floating seats and the baffle can seal the upper space inside the crushing chamber during the crushing process, thus preventing dust from escaping and entering the spray dust suppression chamber.

[0027] By setting up a water collection tank and filter holes, the wastewater during spraying can be collected. In addition, the filter holes can prevent the crushed waste from being discharged and thus unable to be recycled.

[0028] By setting a motor to drive the drive shaft to rotate, the spiral conveyor blades can rotate and transport the crushed waste material that has settled at the bottom of the crushing chamber to the discharge port. This facilitates discharge and also agitates the waste material, preventing it from clogging the filter holes and affecting drainage. Attached Figure Description

Detailed Implementation

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] Example

[0038] like Figure 1-4 As shown, this embodiment provides a technical solution: an environmentally friendly construction waste recycling and processing device, comprising:

[0039] The internally enclosed crushing chamber 3 has a discharge port 8 at the lower end. An end cap is installed at the opening of the discharge port 8. After the end cap is opened, the discharge port 8 can be opened to discharge materials.

[0040] A dust cover 18 is installed inside the crushing chamber 3 and has an open bottom. The dust cover 18 has an inverted U-shaped longitudinal section and is welded to the inner wall of the crushing chamber on both sides along its length, with the welds sealed.

[0041] The feeding bin 2 is located at the top of the crushing bin 3 and is connected to the interior of the dust cover 18. The top of the upper part of the feeding bin 2 is open to facilitate feeding, and its lower part extends into the dust cover 18 and is connected to the interior of the dust cover 18. After feeding, the waste material will fall from the feeding bin 2 into the dust cover 18.

[0042] A crushing component located inside the dust cover 18 and used to crush waste material fed into the crushing chamber 3 from the feeding bin 2;

[0043] Two floating seats 9 are located inside the crushing chamber 3 and can slide freely up and down. The floating seats 9 are correspondingly engaged in the movable space enclosed by the dust cover 18 on both sides and the inner wall of the crushing chamber 3. The two floating seats 9 are driven to move vertically by the lifting component. The two floating seats 9 and the lower space inside the crushing chamber 3 form a spray dust suppression chamber 17.

[0044] A sealing element is used to close the gap between the two floating seats 9 after they move downwards to below the dust cover 18, so that the floating seats 9 can seal the spray dust suppression chamber.

[0045] In the environmentally friendly construction waste recycling and processing device described in this utility model, large-volume waste materials from construction are fed into the crushing component through the feeding bin 2, and the crushing component crushes the waste materials. After crushing, the waste materials fall to the bottom of the spray dust suppression chamber of the crushing bin. During spray dust suppression, feeding is stopped first, and then the lifting component drives two floating seats to move downwards and to below the dust cover. Then, the sealing component seals the gap between the two floating seats, thus sealing the spray dust suppression chamber. The floating seats continue to move downwards, thereby compressing the dust in the spray dust suppression chamber and preventing dust from escaping. Then, the spraying equipment sprays the dust in the spray dust suppression chamber for dust suppression. Because the space for dust to escape is reduced, the dust can be sprayed and suppressed more thoroughly.

[0046] like Figure 1-4As shown, the crushing component includes two horizontally rotatably connected crushing toothed rollers 11 on the crushing chamber 3. The two crushing toothed rollers 11 are located inside the dust cover 18, and they rotate at the same speed but in opposite directions. The two crushing toothed rollers 11 can be driven to rotate synchronously in opposite directions by two geared motors, or a gear can be coaxially connected to each of the two crushing toothed rollers 11. The two gears mesh externally, and one of the gears is driven to rotate by an external motor. In this way, the meshing rotation of the two gears drives the two crushing toothed rollers 11 to rotate synchronously in opposite directions.

[0047] In the environmentally friendly construction waste recycling and processing device described in this utility model, two crushing toothed rollers 11 rotate synchronously in opposite directions, thereby biting the waste material falling between the two crushing toothed rollers 11 into the space between the two crushing toothed rollers 11, and crushing the waste material to reduce its volume.

[0048] like Figure 1-4 As shown, the feeding bin 2 is arranged in a series of constricted openings from top to bottom.

[0049] In the environmentally friendly construction waste recycling and processing device described in this utility model, the feeding bin 2 is arranged in a series of constricted openings from top to bottom, so that the waste can quickly enter the dust cover.

[0050] like Figure 1-4 As shown, the lifting component includes two lifting cylinders 1 symmetrically arranged on the crushing chamber 3 along the center line of the crushing chamber 3. The cylinder rod of the lifting cylinder 1 passes into the crushing chamber 3 and is connected to the floating seat 9.

[0051] In the environmentally friendly construction waste recycling and processing device described in this utility model, two lifting cylinders 1 are vertically installed on the top of the crushing chamber 3. When the cylinder rod of the lifting cylinder 1 is extended, it can drive the floating seat to move downward.

[0052] like Figure 1-4 As shown, the closure includes:

[0053] The translation cylinder 10 is horizontally installed in the mounting cavity 19 opened inside the floating seat 9. The two translation cylinders 10 in the floating seats 9 are symmetrically arranged along the center line of the crushing chamber 3.

[0054] The baffle 12, which is connected to the cylinder rods of the two translation cylinders 10 and is movably connected in the mounting cavity 19, can bring the two baffles 12 closer together until their ends abut against each other when the cylinder rods of the two translation cylinders 10 are extended. This allows the gap between the opposite ends of the two floating seats 9 to be closed, and the two sides of the baffle 12 in the length direction to abut against the inner walls of the opposite sides of the crushing chamber.

[0055] In the environmentally friendly construction waste recycling and processing device described in this utility model, when the floating seat moves downward to below the dust cover, the translation cylinder 10 is activated, its cylinder rod extends, and drives the baffle 12 to move toward the gap between the opposite ends of the two floating seats 9 until the two opposite ends of the two baffles 12 abut together. After abutting, the gap between the two floating seats can be closed. At this time, the two floating seats and the baffle can close the spray dust suppression chamber.

[0056] like Figure 1-4 As shown, multiple spray heads 13 extending into the lower outer wall of the crushing chamber 3 are installed. The spray heads 13 are located inside the dust suppression chamber 17 and are connected to an external water pump through a pipe 7.

[0057] In the environmentally friendly construction waste recycling and treatment device described in this utility model, an external water pump delivers water to the pipeline 7, which then enters the spray head 13. Subsequently, the spray head 13 sprays the crushed waste into the spray dust suppression chamber, while simultaneously spraying and removing dust from the dust in the spray dust suppression chamber.

[0058] like Figure 1-4 As shown, a hollow water collection chamber 6 is fixed to the bottom of the crushing chamber 3. The top wall of the water collection chamber 6 is provided with multiple filter holes 16 that penetrate the bottom of the crushing chamber 3 and are connected to the spray dust suppression chamber 17.

[0059] In the environmentally friendly construction waste recycling and treatment device described in this utility model, the water sprayed will flow into the water collection tank 6 through the filter hole 16 and be collected and stored in the water collection tank 6. The filter hole can prevent waste from entering the water collection tank and affecting the recycling of waste.

[0060] like Figure 1-4 As shown, the outer wall of the water collection tank 6 is provided with a water outlet 5 that communicates with the interior of the water collection tank 6.

[0061] In the environmentally friendly construction waste recycling and treatment device described in this utility model, a manual valve is installed on the water outlet 5. After the manual valve is opened, the water in the water collection tank will flow out from the water outlet 5.

[0062] like Figure 1-4 As shown, a drive shaft 15 is rotatably connected to the lower end of the crushing chamber 3. A spiral conveyor plate 14 is fixedly mounted on the drive shaft 15. The drive shaft 15 is driven to rotate by a motor 4 installed on the outer wall of the crushing chamber 3. The axial direction of the drive shaft 15 is coaxial with the discharge port 8. The motor 4 is powered by an external power source.

[0063] In the environmentally friendly construction waste recycling and processing device described in this utility model, an external power source supplies power to the motor 4, which in turn drives the drive shaft 15 to rotate. After the drive shaft 15 rotates, it drives the spiral conveyor plate 14 to stir the waste accumulated in the spray dust suppression chamber. At the same time, after the discharge port is opened, the waste can be transported to the outside of the discharge port for easy discharge.

[0064] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
