Description

Technical Field

[0001] This invention relates to the field of dust removal technology for construction waste treatment, and in particular to a particulate pollution treatment device for the comprehensive utilization and treatment of construction waste. Background Technology

[0002] The comprehensive utilization of construction waste typically generates significant amounts of particulate matter pollution (such as dust, gravel, and sand). To reduce the environmental impact of this particulate pollution, effective pollution control measures are often necessary. Particulate matter generated during construction waste treatment (such as PM10 and PM2.5) is a major component of air pollution. In recent years, countries worldwide, especially developing countries, have adopted increasingly stringent environmental protection measures to address air pollution, driving the rapid development of air pollution control technologies. The modern environmental protection industry, particularly in the field of air pollution prevention and control, has achieved significant technological advancements, including but not limited to high-efficiency dust removal technologies, low-emission equipment, and air quality monitoring systems.

[0003] The prior art publication CN104971572A provides a dust exhaust gas purification device, which uses an exhaust fan to extract dust-containing air from the workshop. The air enters a water tank through an air inlet pipe, where the dust is absorbed by the water, and the air is discharged through an exhaust pipe. The bottom of the air inlet pipe has multiple round holes on the baffle plate, which can greatly increase the contact area between the air and the water and improve the water absorption efficiency.

[0004] Current technology purifies dust-laden air by drawing it into a water tank. However, continuously drawing dust-laden air into the tank causes air bubbles to form. These bubbles float to the surface, preventing sufficient contact between the airborne dust and the water, thus reducing absorption efficiency. The bubbles also mean that the water's adsorption capacity is incomplete, failing to fully purify the airborne dust. Therefore, reduced purification efficiency may result in a high concentration of dust remaining in the air, failing to meet the expected air quality standards.

[0005] In summary, the existing technology lacks a technique for fully treating dusty air in stages. Summary of the Invention

[0011] Preferably, the push-pull mechanism includes a universal joint A, which is rotatably connected to the inner wall of the segmented dust collection seat. One end of the universal joint A extends through the inner wall of the segmented dust collection seat to the outside and is fixedly connected to an adjusting wheel.

[0012] Preferably, the reciprocating screw has a movable frame that is slidably fitted on its outer wall. The movable frame is slidably fitted through the inner wall of the dust settling chamber.

[0013] Preferably, the outer side of the water pumping base is fixedly connected with multiple drain pipes in a ring structure. The other end of each drain pipe is fixedly connected to one end of the ring pipe. A pipe joint is fixedly connected through one end of the water pumping base.

A water inlet pipe is fixedly connected to the outer end of the pipe joint. The bottom end of the water inlet pipe is fixedly connected through the inner wall of the water storage base. A piston rod is slidably fitted through the inner wall of the water pumping base. A spring is fixedly connected to the inner end of the piston rod. The other end of the spring is fixedly connected to the inner wall of the water pumping base.

[0014] Preferably, the transmission mechanism includes a rotating shaft, which is rotatably connected to the inner wall of the segmented dust settling seat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By opening multiple dust collection chambers on the segmented dust collection seat, the design of the segmented dust collection seat divides the air into multiple parts for processing, which can avoid the burden of large-scale one-time treatment of polluted gas. Through segmented processing, each dust collection chamber can independently and efficiently adsorb and purify dust-laden air, ensuring that each part of the air can fully contact water or other purification media, reducing the risk of secondary pollution, thereby greatly improving purification efficiency and reducing the impact of particulate dust generated during the crushing and utilization of construction waste on the atmosphere;

[0018] 2. By setting up a push-pull mechanism, while the segmented dust collection seat rotates, the dust-laden air can be automatically drawn into the segmented dust collection seat for treatment under the action of the push-pull mechanism, and the treated air can be automatically discharged after treatment. It can automate and precisely control the air suction, treatment and discharge process, which not only improves work efficiency and treatment accuracy, but also enhances the stability and adaptability of the equipment.

[0019] 3. By setting up a transmission mechanism, the piston rod is automatically driven while the segmented dust-collecting seat rotates. Water is sprayed out through the atomizing nozzle, which can improve the dust collection efficiency in the air, reduce water waste, reduce equipment maintenance costs, and enhance the stability and flexibility of the system. This makes the dust collection process more automated, precise, and efficient, which helps to improve overall work efficiency and environmental protection effects, while also playing a positive role in energy conservation and consumption reduction.

Detailed Implementation

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The particulate pollution treatment device for comprehensive utilization and treatment of construction waste shown includes a water storage base 1, a fixed seat 2 fixedly connected to the water storage base 1, a segmented dust suppression seat 3 rotatably connected inside the fixed seat 2, a plurality of air extraction plates 4 slidably connected inside the segmented dust suppression seat 3, a push-pull mechanism 5 slidably connected to one side of the air extraction plate 4, a water extraction seat 6 fixedly connected to the inner wall of the middle part of the segmented dust suppression seat 3, a transmission mechanism 7 on one side of the water extraction seat 6, and an exhaust return seat 8 fixedly connected through one side of the fixed seat 2.

[0031] like Figure 3 As shown, an air inlet pipe 201 is fixedly connected to one side of the top of the fixed base 2. A motor 202 is fixedly connected to the outer wall of one side of the fixed base 2. The output end of the motor 202 extends through the outer wall of the fixed base 2 into the interior and is fixedly connected to the segmented dust settling seat 3. An annular rack 203 is fixedly connected to the inner wall of one side of the fixed base 2. Two arc-shaped racks 204 are fixedly connected to the inner wall of the side of the fixed base 2 connected to the annular rack 203.

[0032] like Figure 4 As shown, the segmented dust-suppressing seat 3 has multiple dust-suppressing chambers 301 arranged in a ring structure. An annular tube 302 is fixedly connected to the inner wall of each dust-suppressing chamber 301 near its opening. Multiple atomizing nozzles 303 are fixedly connected to the annular tube 302 in a ring structure. Multiple rollers 304 are rotatably connected to the outer circumference of the segmented dust-suppressing seat 3 in a ring structure. The rollers 304 are in sliding contact with the inner wall of the fixed seat 2. The rollers 304 make the rotation of the segmented dust-suppressing seat 3 easier.

[0033] By providing multiple dust collection chambers 301 on the segmented dust collection seat 3, the design of the segmented dust collection seat 3 divides the air into multiple parts for processing, which can avoid the burden of large-scale one-time treatment of polluted gas. Through segmented processing, each dust collection chamber 301 can independently and efficiently adsorb and purify dust-laden air, ensuring that each part of the air can fully contact water or other purification media, reducing the risk of secondary pollution, thereby greatly improving purification efficiency and reducing the impact of particulate dust generated during the crushing and utilization of construction waste on the atmosphere.

[0034] like Figure 5 As shown, a sealing gasket is fixedly connected to the outer circle of the suction plate 4, and a groove 401 is provided on one side of the suction plate 4.

[0035] like Figure 5 As shown, the push-pull mechanism 5 includes a universal joint A501, which is rotatably connected to the inner wall of the segmented dust collection seat 3. One end of the universal joint A501 extends through the inner wall of the segmented dust collection seat 3 to the outside and is fixedly connected to an adjusting wheel 502. The adjusting wheel 502 is engaged with an arc-shaped rack 204 for transmission. The other end of the universal joint A501 is fixedly connected to a reciprocating screw 503. The motor 202 drives the connected segmented dust collection seat 3 to rotate. When one of the dust collection chambers 301 moves to the air inlet pipe 201, the arc-shaped rack 204 will drive the engaged adjusting wheel 502 to rotate.

[0036] A movable frame 504 is slidably fitted on the outer wall of the reciprocating screw 503. The movable frame 504 is slidably fitted through the inner wall of the dust settling chamber 301. A transmission rack 505 is fixedly connected to one end of the movable frame 504 inside the dust settling chamber 301. A gear 506 is meshed on one side of the transmission rack 505. A push-pull rod 507 is fixedly connected to the gear 506. One end of the push-pull rod 507 is rotatably connected to the inner wall of the dust settling chamber 301, and the other end of the push-pull rod 507 is slidably fitted to the inner wall of the slide groove 401. The adjusting wheel 502 drives the connected universal joint A501 to rotate, which in turn drives the reciprocating screw 503 to rotate. The reciprocating screw 503 then drives the transmission rack 505 connected to the movable frame 504 to move. The transmission rack 505 then drives the push-pull rod 507 connected to the gear 506 to rotate. This causes the push-pull rod 507 to move the exhaust plate 4 into the dust settling chamber 301, thereby drawing particulate-containing air into the dust settling chamber 301 through the air inlet pipe 201.

[0037] like Figure 6As shown, multiple drain pipes 601 are fixedly connected to the outer side of the water pumping base 6 in a ring structure. The other end of the drain pipe 601 is fixedly connected to one end of the ring pipe 302. A pipe connector is fixedly connected through one end of the water pumping base 6. One end of the pipe connector is sequentially segmented into the inner wall of the dust settling base 3 and the fixed base 2, and is rotatably connected to the fixed base 2. A water inlet pipe 602 is fixedly connected to the outer end of the pipe connector. The bottom end of the water inlet pipe 602 is fixedly connected through the inner wall of the water storage base 1. A piston rod 603 is slidably fitted through the inner wall of the water pumping base 6. A spring 604 is fixedly connected to the inner end of the piston rod 603. The other end of the spring 604 is fixedly connected to the inner wall of the water pumping base 6. The spring 604 resets the piston rod 603. One-way valves are installed in both the drain pipe 601 and the pipe connector.

[0038] like Figure 7 As shown, the transmission mechanism 7 includes a rotating shaft 701, which is rotatably connected to the inner wall of the segmented dust settling seat 3. A driving wheel 702 is fixedly connected to the outer end of the rotating shaft 701. The driving wheel 702 is meshed with the ring rack 203 for transmission. A transmission wheel 703 is fixedly connected to the other end of the rotating shaft 701. A driven wheel 704 is meshed with one side of the transmission wheel 703 for transmission. The driven wheel 704 is rotatably connected to the inner wall of the segmented dust settling seat 3. A pressure wheel 705 is fixedly connected to one end of the driven wheel 704 in an eccentric structure. One end of the pressure wheel 705 is in sliding contact with the outer end of the piston rod 603. Under the action of the ring rack 203, the meshing drive wheel 702 will rotate. At this time, the drive wheel 702 will drive the transmission wheel 703 connected to the rotating shaft 701 to rotate, so that the transmission wheel 703 can drive the pressure wheel 705 connected to the driven wheel 704 to rotate. It will contact and squeeze the piston rod 603, thereby squeezing the water in the water pumping seat 6 into the annular pipe 302 through the drain pipe 601, and spraying it out through the atomizing nozzle 303.

[0039] like Figure 8 As shown, a return pipe 801 is fixedly connected through the bottom of the exhaust return seat 8. The bottom of the return pipe 801 is fixedly connected through the inner wall of the water storage base 1. A filter pipe 802 is placed on the inner wall of the top of the return pipe 801.

[0040] Working principle: When crushing and utilizing construction waste, the motor 202 drives the connected segmented dust-collecting seat 3 to rotate. When one of the dust-collecting chambers 301 moves to the air inlet pipe 201, the arc-shaped rack 204 drives the meshing adjusting wheel 502 to rotate. This causes the adjusting wheel 502 to drive the connected universal joint A501 to rotate, which in turn drives the reciprocating screw 503 to rotate. The reciprocating screw 503 then drives the transmission rack 505 connected to the movable frame 504 to move. This causes the transmission rack 505 to drive the push-pull rod 507 connected to the gear 506 to rotate. This causes the push-pull rod 507 to drive the exhaust plate 4 to move into the dust-collecting chamber 301, thereby drawing air containing particulate matter into the dust-collecting chamber 301 through the air inlet pipe 201.

[0041] Meanwhile, when the segmented dust-collecting seat 3 rotates, the meshing drive wheel 702 will rotate under the action of the annular rack 203. At this time, the drive wheel 702 will drive the transmission wheel 703 connected to the rotating shaft 701 to rotate, so that the transmission wheel 703 can drive the pressure wheel 705 connected to the driven wheel 704 to rotate. Since the pressure wheel 705 is set with an eccentric structure, it will contact and squeeze the piston rod 603, thereby squeezing the water in the water-collecting seat 6 into the annular pipe 302 through the drain pipe 601, and spraying it out through the atomizing nozzle 303 to treat the dust-laden air in the dust-collecting chamber 301.

[0042] When the dust settling chamber 301 moves to the position of the exhaust return seat 8, the push-pull rod 507 will drive the exhaust plate 4 to move to the outside of the dust settling chamber 301 under the action of another arc-shaped rack 204, thereby discharging the treated air through the exhaust return seat 8 and pushing out the water sprayed into the dust settling chamber 301. After being filtered by the filter tube 802 in the return pipe 801, the water flows back to the water storage base 1 for reuse.
