Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a dust reduction system for recycled concrete processing. Background Art

[0002] When the workshop for recycled concrete processing is operating, since there will be a large amount of dust when the concrete is crushed, it is necessary to carry out dust reduction treatment on the dust to maintain the working environment.

[0003] After retrieval, the patent with the authorization number of CN212017201U in China discloses a dust reduction device for concrete production. Although this dust reduction device for concrete production fixes a spray head at the top of the dust reduction device body, and the spray head sprays water on the gas with dust particles, and the water filters the dust particles in the gas to achieve the dust removal effect, the spray head has high requirements for water quality. Therefore, it is necessary to filter the recycled water. Although the device is provided with a filter plate to filter the circulating water, when the filter plate filters the sewage with a large dust content, the filter plate needs to be frequently cleaned or replaced, which is rather troublesome and reduces the convenience of using the device. Summary of the Invention

[0004] One of the purposes of this application is to provide a dust reduction system for recycled concrete processing to solve the problem that the existing dust reduction mechanism has high requirements for water quality due to spraying through a spray head, so the filtering mechanism needs to be frequently cleaned and replaced.

[0005] To achieve the above purposes, the technical solution adopted in this application is: a dust reduction system for recycled concrete processing, including a base, a maintenance mechanism, a purification mechanism, and a filtering mechanism. A control device is installed on one side of the base. The inner side of the base is welded to the maintenance mechanism. An air inlet is arranged at the top of the maintenance mechanism. A purification mechanism is installed at the top of the air inlet. An air outlet is installed at the top of the purification mechanism. A lifting pump is installed at one side of the bottom of the air outlet through screws. One end of the lifting pump is communicated with one end of a spray pipe. The other end of the spray pipe is located inside the air outlet. One end of the bottom of the lifting pump is communicated with a lifting pipe. The bottom of the lifting pipe is communicated with a sewage disposal mechanism. A filtering mechanism is installed at the top of the sewage disposal mechanism. The top of the filtering mechanism is connected to the bottom of the maintenance mechanism. An inlet is arranged on one side of the maintenance mechanism and is communicated with the inside.

[0006] Preferably, the maintenance mechanism includes a maintenance bin welded to the bottom of the air inlet. A hole is opened on one side of the maintenance bin. A maintenance board is arranged inside the hole. One end of the maintenance board is rotatably connected to the maintenance bin through a hinge. The other end of the maintenance board is connected to the maintenance bin through a buckle. By unfastening the buckle, one end of the maintenance board can rotate around the hinge, and then the maintenance board can be opened, which is convenient for taking out the internal filter screen for cleaning and replacement.

[0007] Preferably, the purification mechanism includes a purification chamber welded to the top of the air inlet, and the purification chamber is provided with three, and the three purification chambers are connected to each other end to end, a guide block is welded inside the purification chamber, and fan blades are provided at the bottom of the guide block, and the fan blades are sleeved on the outside of the rotating shaft, and one end of the top of the rotating shaft is sleeved on the outside of the output end of the driving motor, and the driving motor is installed on the top of the air outlet by screws, and the lifting pump transports the water at the bottom of the device to the spray pipe through the lifting pipe, and then the spray pipe will transport the water to the top of the purification chamber of the purification mechanism, and the rotating shaft can be rotated under the action of the driving motor, and the rotating shaft is rotated. The rotation of the fan can drive the fan blades to rotate at the same time, so that the external air can enter the purification chamber from the air inlet through the suction force of the fan blades. The water transported to the top of the purification chamber by the sprinkler pipe can fall down inside the purification chamber under the action of gravity, and then come into contact with the high-speed rotating fan blades, so that the fan blades can break up the water and atomize it. The atomized water can come into contact with the rising air inside the purification chamber so that the dust can be adsorbed in the water particles. Under the action of gravity, the sewage with dust descends, and the air with dust removed rises under the action of the fan blades, and is finally discharged from the air outlet, thereby reducing dust.

[0008] Preferably, the inner wall of the guide block is in sliding contact with the outer wall of the rotating shaft, and the surface of the guide block is provided with grooves in a circular and evenly spaced pattern, and the grooves are in a bucket-shaped structure. Water droplets containing dust are gathered through the guide block, and then gathered through the cone shape inside the guide block and fall into contact with the rotating fan blades below.

[0009] Preferably, the filter mechanism includes a bottom bin welded to the bottom of the maintenance bin, the bottom bin is conical, a support plate is welded on the inner side of the top of the bottom bin, a hole groove is opened on the surface of the support plate, a filter screen is placed on the top surface of the support plate, an overflow hole is threadedly connected to the middle part of the top of the support plate, the interior of the overflow hole is hollow, the bottom of the overflow hole is connected to the bottom of the support plate, and a liquid level sensor is embedded on one side of the top of the overflow hole, the liquid level sensor is electrically connected to the alarm, sewage with dust falls on the surface of the filter screen on the surface of the filter mechanism, and water filtered through the surface of the filter screen will fall into the sedimentation bin for reuse through the holes and grooves on the surface of the support plate. When the dust on the surface of the filter screen blocks the mesh holes, the water level will continue to rise on the surface of the filter screen, and then submerge the overflow hole, and flow into the sedimentation bin through the overflow hole, which is conducive to avoiding sewage overflow.

[0010] Preferably, the sewage discharge mechanism includes a sedimentation bin connected to the bottom of the bottom bin, the bottom of the sedimentation bin is glued to the observation bin, the observation bin is made of transparent glass, one side of the sedimentation bin is connected to the drain pipe, and the other side of the sedimentation bin is connected to the sewage outlet, and the drainage pipe is connected to one end of the bottom of the lifting pipe. The observation bin made of transparent glass is conducive to observing the internal water quality, and when the water quality is too poor, the internal sewage can be discharged through the sewage outlet.

[0011] Compared with the prior art, the beneficial effects of the present application are as follows:

[0012] (1) In this dust reduction system for recycled concrete processing, the lifting pump transports water from the bottom of the device to the spray pipe through a lifting pipe. The spray pipe further transports the water to the top of the purification chamber. Under the action of the driving motor, the rotating shaft drives the fan blades to rotate, generating suction, so that external air enters the purification chamber through the fan blades from the air inlet. Under the action of gravity, the water contacts the fan blades and is broken up into an atomized state, contacts the rising air, and makes dust adsorb on the water particles to form water droplets. These water droplets gather and fall through the internal grooves of the guide block, contact the dust in the air again, are continuously broken up and gathered, and finally gather at the bottom of the device. This design avoids the use of atomizing nozzles, reduces the water quality requirements, and reduces the cleaning frequency of the filtering mechanism.

[0013] (2) In this dust reduction system for recycled concrete processing, when sewage flows through the surface of the filter screen, dust and other particulate matters are intercepted, and the filtered water flows into the sedimentation chamber through the holes and grooves on the surface of the support plate for reuse. In order to ensure the filtering efficiency and the normal operation of the equipment, a liquid level sensor is designed to monitor the water level on the surface of the filter screen. Once too much dust accumulates and clogs the pores of the filter screen, causing the water level to rise and submerge the overflow holes, the water will flow into the sedimentation chamber through the overflow holes. At this time, the liquid level sensor will trigger the alarm to send an alarm signal to prompt the staff to conduct inspections and maintenance. The staff can then open the inspection plate of the inspection mechanism to clean or replace the filter screen in a timely manner, thus ensuring the continuous operation and high efficiency of the filtering system.

[0014] Thus, it solves the problem that the existing dust reduction mechanism has high requirements for water quality due to spraying through atomizing nozzles, so the filtering mechanism needs to be frequently cleaned and replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] One of the preferred embodiments of this application is as follows: Figures 1 to 2As shown, the dust reduction system for recycled concrete processing includes a base 1, an inspection mechanism 2, a purification mechanism 4 and a filtering mechanism 8. A control device 11 is installed on one side of the base 1, and the inner side of the base 1 is welded to the inspection mechanism 2. An air inlet 3 is provided on the top of the inspection mechanism 2, a purification mechanism 4 is installed on the top of the air inlet 3, an air outlet is installed on the top of the purification mechanism 4, and a lifting pump 7 is installed on one side of the bottom of the air outlet by screws. One end of the lifting pump 7 is connected to one end of the spray pipe 6, and the other end of the spray pipe 6 is located inside the air outlet 5. One end of the bottom of the lifting pump 7 is connected to the lifting pipe 12, and the bottom of the lifting pipe 12 is connected to the sewage discharge mechanism 9. The top of the sewage discharge mechanism 9 is equipped with a filtering mechanism 8. The top of the filter mechanism 8 is connected to the bottom of the maintenance mechanism 2. A water inlet 10 is provided on one side of the maintenance mechanism 2 and is communicated with the interior. The purification mechanism 4 includes a purification chamber 402 welded to the top of the air inlet 3. There are three purification chambers 402, and the three purification chambers 402 are connected end to end. A guide block 404 is welded inside the purification chamber 402. A fan blade 403 is provided at the bottom of the guide block 404. The fan blade 403 is mounted on the outside of the rotating shaft 401. One end of the top of the rotating shaft 401 is mounted on the outside of the output end of the driving motor. The driving motor is installed on the top of the air outlet 5 by screws. The inner wall of the guide block 404 is in sliding contact with the outer wall of the rotating shaft 401, and the surface of the guide block 404 is annular. The purifier 402 of the present invention is provided with grooves in a regular pattern with equal spacing, and the grooves are in a bucket-shaped structure. When in use, the lifting pump 7 transports the water at the bottom of the device to the spray pipe 6 through the lifting pipe 12, and then the spray pipe 6 transports the water to the top of the purification chamber 402 of the purification mechanism 4. The rotating shaft 401 can be rotated by the driving motor, and the rotating shaft 401 can drive the fan blades 403 to rotate while rotating, so that the external air can enter the purification chamber 402 from the air inlet 3 through the suction force of the fan blades 403. The water transported to the top of the purification chamber 402 by the spray pipe 6 can fall downward inside the purification chamber 402 under the action of gravity, and then The high-speed rotating fan blades 403 make contact with the water, so that the fan blades 403 can break up the water and atomize the water. The atomized water can come into contact with the rising air inside the purification chamber 402 so that the dust can be adsorbed in the water particles. After becoming water droplets, they are gathered through the internal grooves of the guide block 404 and continue to fall, so that the dust in the air can come into contact with the falling water again, and then the water with dust attached can be continuously broken up and gathered, and finally gathered at the bottom of the device. The device avoids the use of an atomizing nozzle, and uses the fan blades 403 to break up the water and contact it with the air, thereby achieving the effect of dust reduction. Therefore, the requirements for water quality are relatively low, thereby avoiding frequent cleaning of the filter mechanism 8.

[0026] One of the preferred embodiments of this application is as follows: Figures 1 to 5As shown in the figure, the filtering mechanism 8 includes a bottom bin 801 welded to the bottom of the maintenance bin 201. The bottom bin 801 is conical in shape. Inside the top of the bottom bin 801, a support plate 802 is welded. The surface of the support plate 802 is provided with hole slots. On the top surface of the support plate 802, a filter screen 803 is placed. In the middle of the top surface of the support plate 802, an overflow hole 806 is connected by threads.

The maintenance mechanism 2 includes a maintenance bin 201 welded to the bottom of an air inlet 3. A hole slot is provided on one side of the maintenance bin 201. Inside the hole slot, a maintenance plate 203 is arranged. One end of the maintenance plate 203 is rotatably connected to the maintenance bin 201 through a hinge 202. The other end of the maintenance plate 203 is connected to the maintenance bin 201 through a buckle 204. The sewage with dust adheres to the surface of the filter screen 803 on the surface of the filtering mechanism 8. The water filtered through the surface of the filter screen 803 will fall into the sedimentation bin 903 through the hole slots on the surface of the support plate 802 for reuse. When there is a lot of dust on the surface of the filter screen 803 and the mesh holes are blocked, the water level will continuously rise on the surface of the filter screen 803, and then submerge the overflow hole 806, and flow into the sedimentation bin 903 through the overflow hole 806. At the same time, the liquid level sensor 805 will be triggered. Then, the liquid level sensor 805 will alarm through the alarm 804, so that the staff can open the maintenance plate 203 of the maintenance mechanism 2 to clean and replace the filter screen 803 in time.
