Description

Technical Field

[0001] The present invention relates to the technical field of concrete production, and particularly relates to a production device for ecological concrete. Background Art

[0002] A large amount of construction waste is generated during construction and development, mainly including waste sand, waste clay bricks, waste concrete, etc. A large amount of waste clay bricks and waste concrete in the construction waste can be prepared into recycled aggregates through reasonable process equipment for the production of ecological concrete. When the waste clay bricks and concrete are crushed and screened, a large amount of dust will be generated, and dust removal equipment is required to handle the dust. Therefore, the dust removal equipment is essential in the production process of ecological concrete.

[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] Embodiment: Please refer to Figures 1-8, A production device for ecological concrete, including a waste conveying device 2, a crushing device 3, a screening device 4, a transfer device 5, a dust removal device 1, and a mixing and stirring device 51. The waste in the building, such as waste bricks and waste concrete, is sent to the crushing device 3 through the waste conveying device 2 for crushing treatment. The waste that meets the particle size requirements is screened out by the screening device 4 for recycling and reused as raw materials for producing concrete. The screened materials are sent into the mixing and stirring device 51 through the transfer device 5 to be mixed and stirred with other raw materials to produce new concrete. Among them, during the concrete production process, a large amount of dust will be generated during the crushing and screening processes of the waste, and the dust needs to be extracted and treated by the dust removal device 1;

[0054] The dust removal device 1 includes:

[0055] Two dry treatment boxes 6, which are fixedly connected together. An air inlet pipe 8 is connected to the outer wall of one of the dry treatment boxes 6, and an air extraction device 9 is installed on the air inlet pipe 8. A switching channel 10 is provided between the two dry treatment boxes 6. A guide pipe 11 is installed on the top of the dry treatment box 6, and the other end of the guide pipe 11 is connected to the adjacent wet treatment box 7; Two wet treatment boxes 7, which are respectively fixedly connected to the outer walls on the opposite sides of the two dry treatment boxes 6. A plurality of shunt pipes 12 are installed on the top of the wet treatment box 7, and a plurality of atomizing nozzles 13 are installed at the bottom of each of the plurality of shunt pipes 12. An exhaust hole is also provided on the top of the wet treatment box 7; A perforated plate 14 is also installed inside the wet treatment box 7, and a sewage discharge pipe 41 is installed at the bottom of the wet treatment box 7. A solenoid valve is installed on the sewage discharge pipe 41, and a liquid level sensor is installed inside the wet treatment box 7. When the liquid level sensor detects that the liquid level inside the wet treatment box 7 reaches the set value, it controls the solenoid valve to open and discharge the sewage. When the sewage inside the wet treatment box 7 does not reach the set value, it controls the solenoid valve to close;

[0056] The dust generated during the crushing and screening processes of the waste is introduced into the left dry treatment box 6 through the air inlet pipe 8 by the air extraction device 9 for filtration treatment. The filtered gas is discharged into the wet treatment box 7 through the guide pipe 11, and the remaining fine dust in the gas discharged into the wet treatment box 7 is dusted by the atomizing nozzles 13. The dusted mixed water flows downward through the perforated plate 14.

[0057] A filtering trigger mechanism is arranged inside the dry treatment box 6 and is used for filtering the gas pumped into the inside of the dry treatment box 6, and is also used for sending a signal when the filtering is blocked. The filtering trigger mechanism includes a frame 15 slidably connected inside the dry treatment box 6, a filter net 16 installed inside the frame 15, and a pressure sensor 17 arranged above the filter net 16; a plurality of first telescopic rods 18 are fixedly connected to the inner wall of the top of the dry treatment box 6, the extending end of the first telescopic rod 18 is fixedly connected to the top of the frame 15, a first spring 19 is sleeved outside the first telescopic rod 18, the top end of the first spring 19 is fixedly connected to the inner wall of the top of the dry treatment box 6, and the bottom end of the first spring 19 is fixedly connected to the top of the frame 15; a support column 20 is also fixedly connected to the inner wall of the top of the dry treatment box 6, and the pressure sensor 17 is installed at the bottom end of the support column 20;

[0058] When the gas enters the inside of the left dry treatment box 6, the gas is filtered by the filter net 16. When the filter net 16 starts to be blocked on a large area, due to the obstruction of the filter net 16, it will start to move upward, the frame 15 moves upward accordingly, and the first spring 19 and the first telescopic rod 18 start to contract. When the filter net 16 abuts against the pressure sensor 17, the pressure sensor 17 detects the pressure and transmits the pressure signal to the controller, and the controller controls the motor 25 on the left to drive the first transmission shaft 24 to rotate;

[0059] When the filter net 16 inside the right dry treatment box 6 is blocked and its internal pressure sensor 17 transmits the pressure signal to the controller, first control the motor 25 on the right to drive the right closing plate 21 to close the bottom of the filter net 16, and then the controller controls the motor 25 on the left to drive the left closing plate 21 to move leftward to reset.

[0060] A closed cleaning mechanism is arranged inside the wet treatment box 7 and is used to move into the dry treatment box 6 when the filter trigger mechanism is blocked to close and clean the filter trigger mechanism. The closed cleaning mechanism includes a closed plate 21 arranged inside the wet treatment box 7, a scraper 22 arranged on the top of the closed plate 21, and a driving component for driving the closed plate 21 and the scraper 22 to move synchronously; the closed plate 21 is located below the orifice plate 14; a through groove 23 is provided between the wet treatment box 7 and the dry treatment box 6 for passing the closed plate 21 and the scraper 22, and the driving component includes two first transmission shafts 24 rotatably connected to the inside of the wet treatment box 7 and a motor 25 installed on the outer wall of the wet treatment box 7; the outer parts of the two first transmission shafts 24 are fixedly sleeved with first A reciprocating screw 26, the outside of the two first reciprocating screws 26 is screwed with a linkage plate 27; one end of the closing plate 21 is fixedly connected to two connecting blocks 28, and the linkage plate 27 and the connecting block 28 are connected by a second spring 29; one end of the two first transmission shafts 24 extends to the outside of the wet treatment box 7, and the outside of the output shaft of the motor 25 is fixedly sleeved with a driving gear 30, and the outside of one of the first transmission shafts 24 is installed with a first one-way gear 31, and the driving gear 30 is meshed with the first one-way gear 31. The two first transmission shafts 24 are connected by a first transmission member 32, and the first transmission member 32 includes two synchronous wheels fixedly sleeved on the outside of the two first transmission shafts 24 and a synchronous belt connected to the outside of the two synchronous wheels;

[0061] When the filter screen 16 abuts against the pressure sensor 17, the filter screen 16 stops moving upward, and the control motor 25 drives the driving gear 30 to rotate forward, and the first transmission shaft 24 is driven to rotate through the meshing effect between the driving gear 30 and the first one-way gear 31. At this time, the second one-way gear 49 also rotates accordingly, but the second transmission shaft 47 does not rotate accordingly. When the first transmission shaft 24 rotates, the two first transmission shafts 24 are connected by the first transmission member 32 to keep the synchronous rotation, thereby driving the two first reciprocating screws 26 to rotate synchronously, and the linkage plate 27 moves along the outside of the first reciprocating screw 26 toward the inside of the dry treatment box 6, and the closing plate 21 and the scraper strip 22 are pushed toward The dry treatment box 6 moves inside, the second reciprocating screw 48 slides synchronously along the outside of the second transmission shaft 47, and the closing plate 21 moves to the bottom of the filter 16 to close the bottom of the filter 16. After the closing plate 21 closes the bottom of the filter 16, the frame 15 slowly falls down due to the rebound force of the first spring 19, thereby driving the filter 16 to slowly fall down, and the top of the scraper bar 22 abuts against the bottom of the frame 15 and the filter 16. When the first reciprocating screw 26 is continued to be driven to rotate by the control motor 25, the closing plate 21 and the scraper bar 22 are driven by the linkage plate 27 to move and reset toward the inside of the wet treatment box 7. The dust at the bottom of the filter 16 is cleaned at the top of the closing plate 21 through the friction between the scraper bar 22 and the bottom of the filter 16.

[0062] Replace the filtering mechanism, which is arranged inside one of the dry treatment boxes 6 and is connected to the closed cleaning mechanism for controlling the opening and closing of the switching channel 10. There are two filtering mechanisms for replacement. The filtering mechanism for replacement includes a conduit 33 fixedly connected inside the dry treatment box 6, a driving rod 34 fixedly connected to the outer wall of one side of the linkage plate 27, and a baffle 35 slidably connected inside the switching channel 10; a first piston 36 is installed horizontally inside the conduit 33, and the first piston 36 is on the same horizontal line as the driving rod 34; a second piston 37 is installed vertically inside the conduit 33. A third spring 38 is fixedly connected to the top of the second piston 37, a lifting rod 39 is fixedly connected to the bottom of the second piston 37, and the bottom end of the lifting rod 39 is fixedly connected to the top of the baffle 35; an extension groove 40 communicating with the switching channel 10 is opened at the bottom of the dry treatment box 6;

[0063] After the closing plate 21 moves towards the inside of the dry treatment box 6 and completely closes the bottom of the filter net 16, as the linkage plate 27 continues to move, the second spring 29 begins to be compressed, and the driving rod 34 begins to abut against the first piston 36 and drives the first piston 36 to move to the right along the inner wall of the conduit 33. When the first piston 36 moves to the right, it pushes the hydraulic oil inside the conduit 33 to drive the second piston 37 to move downward, and the third spring 38 is stretched. When the second piston 37 moves downward, it drives the lifting rod 39 to move downward, thereby driving the baffle 35 to move downward, opening the switching channel 10, and the gas inside the left dry treatment box 6 can enter the right dry treatment box 6 through the switching channel 10, and the gas is filtered by the filter net 16 inside the right dry treatment box 6, so as to achieve the effect of alternately filtering the gas;

[0064] After the right filter net 16 is blocked and its bottom is closed, drive the linkage plate 27 on the left to move leftward and reset, and the driving rod 34 moves synchronously. At this time, through the resilience of the third spring 38, drive the second piston 37 to move upward, drive the first piston 36 to move leftward and reset by pushing the hydraulic oil inside the conduit 33. When the second piston 37 moves upward, drive the baffle 35 to move upward synchronously through the lifting rod 39 to close the switching channel 10, so that the gas is filtered again through the filter net 16 inside the left dry treatment box 6.

[0065] A pressure relief mechanism is installed at the bottom of one of the dry treatment boxes 6 and is used to automatically relieve the pressure inside the dry treatment box 6 when the filter trigger mechanism becomes blocked. The pressure relief mechanism includes a telescopic cylinder 42 installed at the bottom of the dry treatment box 6, a sealing disc 43 fixedly connected to the bottom end of the telescopic cylinder 42, and a plurality of second telescopic rods 44 fixedly connected to the bottom of the dry treatment box 6. A dust discharge cover 45 is screwed inside the sealing disc 43. A fourth spring 46 is sleeved outside the second telescopic rod 44. The extended end of the second telescopic rod 44 and the bottom end of the fourth spring 46 are both fixedly connected to the top of the sealing disc 43. The top end of the fourth spring 46 is fixedly connected to the bottom of the dry treatment box 6. The elastic force of the fourth spring 46 is greater than the elastic force of the first spring 19.

[0066] When one of the filter meshes 16 becomes blocked, the first spring 19 contracts first. When the filter mesh 16 abuts against the pressure sensor 17 and cannot move further, and the first spring 19 cannot contract further, as the gas continues to enter, the fourth spring 46 begins to be stretched, the telescopic cylinder 42 begins to extend, and the gas enters the inside of the telescopic cylinder 42 for pressure relief. After the control switching channel 10 changes the gas filtration channel, through the resilience of the fourth spring 46, the gas inside the telescopic cylinder 42 is pressed into the dry treatment box 6. A part of the dust will accumulate inside the telescopic cylinder 42. When it is necessary to clean the dust, unscrew the dust discharge cover 45, and the dust inside the telescopic cylinder 42 can be discharged.

[0067] A dry-wet mixing cleaning mechanism is connected to the closed cleaning mechanism and is used to process the removed dust after the closed cleaning mechanism cleans the filter trigger mechanism and moves back to the wet treatment box 7. The dry-wet mixing cleaning mechanism includes two second transmission shafts 47 rotatably connected inside the wet treatment box 7 and a linkage assembly for driving the two second transmission shafts 47 to rotate. Second reciprocating screws 48 are slidably sleeved outside the two second transmission shafts 47. A scraping strip 22 is screwed outside the second reciprocating screw 48. One end of the second reciprocating screw 48 is rotatably connected to the outer wall of one side of the connecting block 28. One end of each of the two second transmission shafts 47 extends outside the wet treatment box 7. Through holes are formed through the inside of the linkage plate 27 and the connecting block 28. The second transmission shaft 47 passes through the two through holes on the linkage plate 27 and the connecting block 28 in sequence and does not contact the through holes. The linkage assembly includes a second one-way gear 49 installed outside one of the second transmission shafts 47 and a second transmission member 50 drivingly connected between the two second transmission shafts 47. The second transmission member 50 includes two synchronous wheels respectively fixedly sleeved outside the two second transmission shafts 47 and a synchronous belt drivingly connected outside the two synchronous wheels. The second one-way gear 49 meshes with the driving gear 30.

[0068] After the closing plate 21 and the scraping strip 22 are moved back into the wet treatment tank 7, the dust scraped by the scraping strip 22 is also carried into the wet treatment tank 7. The dust-removing water flowing downward through the orifice plate 14 is mixed with the dust on the top of the closing plate 21, so that part of the scraped dust is carried away by the dust-removing water. By controlling the motor 25 to drive the driving gear 30 to reverse, through the meshing effect between the driving gear 30 and the second one-way gear 49, one of the second transmission shafts 47 is driven to rotate. At this time, the first one-way gear 31 also rotates accordingly, but the first transmission shaft 24 does not rotate accordingly. When the second transmission shaft 47 rotates, through the transmission connection of the second transmission member 50, the two second transmission shafts 47 are kept rotating synchronously, thereby driving the two second reciprocating screws 48 to rotate synchronously, and then driving the scraping strip 22 to move along the top of the closing plate 21 to scrape off the dust and water mixture on the top of the closing plate 21. After the mixture is scraped off, it falls and is mixed with the dust-removing water at the bottom. When it is necessary to drive the closing plate 21 into the dry treatment tank 6, first control each shunt pipe 12 to notify the water supply, then control the motor 25 to continue driving the second reciprocating screw 48 to rotate, drive the scraping strip 22 to move along the top of the closing plate 21 in the direction of the dry treatment tank 6 to reset, scrape off the dust-removing water on the top of the closing plate 21, and then drive the closing plate 21 and the scraping strip 22 into the dry treatment tank 6, and then supply water to the shunt pipe 12 again.

[0069] Working principle: When in use, the dust generated during the crushing and screening processes of waste materials is introduced into the interior of the dry treatment box 6 on the left through the air inlet pipe 8 by the air extraction device 9. The filter net 16 filters the gas. The gas after filtration is discharged into the interior of the wet treatment box 7 through the air guide pipe 11. The atomizing nozzle 13 performs dust reduction treatment on the fine dust remaining in the gas discharged into the interior of the wet treatment box 7. The dust reduction mixed water flows downward through the orifice plate 14. When a large area blockage occurs in the filter net 16, due to the obstruction of the filter net 16, it will start to move upward, and the frame 15 will move upward accordingly. The first spring 19 and the first telescopic rod 18 start to contract. When the filter net 16 abuts against the pressure sensor 17, the pressure sensor 17 detects the pressure and transmits the pressure signal to the controller. The controller controls the motor 25 on the left to drive the first transmission shaft 24 to rotate, and then drives the two first reciprocating screws 26 to rotate synchronously. The linkage plate 27 then moves along the outside of the first reciprocating screw 26 towards the interior of the dry treatment box 6. Through the connection of the second spring 29 and the connecting block 28, the closing plate 21 and the scraping strip 22 are pushed towards the interior of the dry treatment box 6. The second reciprocating screw 48 slides synchronously along the outside of the second transmission shaft 47. The closing plate 21 moves to the lower part of the filter net 16 to close the lower part of the filter net 16. After the closing plate 21 closes the bottom of the filter net 16, the frame 15 slowly drops under the action of the elastic force of the first spring 19, and then drives the filter net 16 to slowly drop. The top of the scraping strip 22 abuts against the bottom of the frame 15 and the filter net 16. As the linkage plate 27 continues to move, the second spring 29 starts to be compressed, and the driving rod 34 starts to abut against the first piston 36 and drives the first piston 36 to move to the right along the inner wall of the conduit 33. When the first piston 36 moves to the right, it pushes the hydraulic oil inside the conduit 33 to drive the second piston 37 to move downward. The third spring 38 is stretched. When the second piston 37 moves downward, it drives the lifting rod 39 to move downward, thereby driving the baffle 35 to move downward to open the switching channel 10. The gas inside the dry treatment box 6 on the left can enter the dry treatment box 6 on the right through the switching channel 10, and the gas is filtered by the filter net 16 inside the dry treatment box 6 on the right. After the filter net 16 on the right is also blocked, the motor 25 on the right is controlled to drive the closing plate 21 on the right to close the bottom of the filter net 16, and then the linkage plate 27 on the left is driven to move leftward to reset, and the driving rod 34 moves synchronously. At this time, through the resilience of the third spring 38, the second piston 37 is driven to move upward, and the first piston 36 is driven to move leftward to reset by pushing the hydraulic oil inside the conduit 33. When the second piston 37 moves upward, the baffle 35 is driven to move upward synchronously through the lifting rod 39 to close the switching channel 10, so that the gas is filtered again through the filter net 16 inside the dry treatment box 6 on the left. When the linkage plate 27 moves, it drives the closing plate 21 and the scraping strip 22 to move back towards the interior of the wet treatment box 7. Through the friction between the scraping strip 22 and the bottom of the filter net 16,The dust at the bottom of the filter net 16 is cleaned onto the top of the closing plate 21. After the closing plate 21 and the scraping bar 22 are moved back into the wet treatment tank 7, the dust scraped by the scraping bar 22 is also carried into the wet treatment tank 7. The dust-removing water flowing downward through the orifice plate 14 is mixed with the dust on the top of the closing plate 21, so that part of the scraped dust is carried away by the dust-removing water. By controlling the motor 25 to drive the two second transmission shafts 47 to rotate synchronously, the two second reciprocating screws 48 are driven to rotate synchronously, and then the scraping bar 22 is driven to move along the top of the closing plate 21 to scrape off the dust-water mixture on the top of the closing plate 21. After the mixture is scraped off, it falls and is mixed with the dust-removing water at the bottom, so that the dust is fused in the water and will not be raised when discharged.
