Description

Technical Field

[0001] The invention relates to the technical field of gypsum regeneration processing, and in particular to a device and a method for producing regenerated gypsum using solid waste. Background Art

[0002] Solid waste generated by the industrial sector can be used to produce gypsum through a regeneration device. After searching, it was found that China Utility Model Patent Publication No. CN216368166U discloses a solid waste for the production of regenerated gypsum. In this technical solution, the solid waste is crushed and dissolved in water, so that the dihydrate gypsum in the solid waste can be dissolved in water, and then the dissolved dihydrate gypsum and the mixed liquid are heated and dehydrated to finally obtain the regenerated gypsum.

[0003] In the above technology, after dihydrate gypsum is dissolved in water, it will be in the form of a suspension. When dehydrating, the suspension needs to be transported to a heating device for heating and dehydration. Due to the large water content, the heating process is relatively lengthy, which leads to a decrease in the regeneration processing efficiency of the regenerated gypsum. In addition, after the suspension is heated and dehydrated, the regenerated gypsum is also in the form of sludge or powder, which is difficult to collect, causing a certain degree of inconvenience to subsequent operations and processing. Summary of the invention

[0004] The object of the present invention is to provide a device and a method for producing regenerated gypsum using solid waste, so as to solve the problems raised in the above-mentioned background technology.

[0008] A sliding baffle plate engaged in a sliding groove provided in a side wall of the fixing seat, wherein the sliding baffle plate slides freely horizontally in the sliding groove and closes an opening at a lower side of the compacting bin;

[0009] A compaction drive unit is installed in the crushing bin, wherein the output end of the compaction drive unit is fixedly connected with a connecting sleeve, the bottom end of the connecting sleeve is fixedly connected with a pressing plate, the pressing plate forms a sliding fit with the inner cavity wall of the compaction bin, and a water seepage unit is provided on the pressing plate.

[0010] Through the above technical scheme, the compaction drive unit drives the pressing plate to move in the compaction bin, and causes the pressing plate to generate pressure on the dihydrate gypsum sediment layer in the compaction bin, so that the dihydrate gypsum sediment layer is squeezed into a cake shape, thereby reducing the water content of the dihydrate gypsum sediment layer. Therefore, during the subsequent heating and dehydration, the dehydration time of the dihydrate gypsum is shortened, thereby improving the regeneration processing efficiency of the regenerated gypsum. In addition, since the volume of the dihydrate gypsum is relatively fixed after being compacted, it is convenient to collect.

[0011] Furthermore, two crushing tooth rollers are horizontally rotatably connected via a rotating shaft installed in the crushing bin, a gear reducer is installed on the outer wall of the crushing bin, the gear reducer is drivingly connected to the rotating shaft on the two crushing tooth rollers, and a motor is installed on the outer wall of the gear reducer, the motor is drivingly connected to the gear reducer.

[0012] Through the above technical solution, the motor drives the gear reducer to rotate, so that the gear reducer drives the two rotating shafts to rotate synchronously in opposite directions, thereby causing the two crushing tooth rollers to rotate accordingly. The two crushing tooth rollers can squeeze and crush the solid waste fed into the feeding port.

[0013] Furthermore, the compaction drive unit includes a drop ramp plate obliquely fixed to the inner wall of the crushing bin, the lower end of the drop ramp plate in the oblique direction and the inner wall of the crushing bin form a drop channel, and a hydraulic cylinder is vertically installed on the downward side of the drop ramp plate, and the piston rod end of the hydraulic cylinder is fixedly connected to the connecting sleeve.

[0014] Through the above technical scheme, solid waste falls from the feeding port onto the surface of the falling inclined plate, slides along the surface of the falling inclined plate to the falling channel, and then falls into the transition bin and the compacting bin. The piston rod of the hydraulic cylinder extends and drives the pressing plate to move downward, so that the pressing plate is engaged in the compacting bin, thereby squeezing the dihydrate gypsum suspension in the compacting bin.

[0015] Furthermore, the outer wall of the transition bin is provided with a water opening, and the water opening is connected with the interior of the transition bin.

[0016] Through the above technical solution, water can be transported to the transition bin through the water opening, and water in the transition bin can also be pumped out through the water opening.

[0017] Furthermore, a cylinder bracket is fixedly connected to the side wall of the fixing seat, a push-pull cylinder is horizontally installed on the outer wall of the cylinder bracket, and the cylinder rod end of the push-pull cylinder is fixedly connected to the outer wall of the sliding baffle.

[0018] Through the above technical solution, the sliding baffle is driven by the push-pull cylinder to slide in the sliding groove of the fixed seat, so that the lower side opening of the compacting bin can be opened or closed.

[0019] Furthermore, a through groove is formed at one end of the sliding baffle, and a floating mounting block is mounted in the through groove. The floating mounting block slides vertically and freely in the through groove, and a plurality of cutting knives are fixedly connected to the upper surface of the floating mounting block. A cutting knife lifting unit is provided on the sliding baffle, and the cutting knife lifting unit is used to drive the floating mounting block to move upward first and then downward when the sliding baffle moves horizontally.

[0020] Through the above technical solution, when the sliding baffle moves horizontally, the blade lifting unit drives the floating mounting block to move upward, so that the blade protrudes to the top of the sliding baffle and enables the blade to cut the cake-shaped dihydrate gypsum, so that the dihydrate gypsum is cut into multiple parts, so that the heating area of ​​the dihydrate gypsum is larger when it is heated and dehydrated, thereby improving the dehydration efficiency of the dihydrate gypsum.

[0021] Furthermore, the cutting knife lifting unit includes a sliding pin fixed to the outer walls on both sides of the floating mounting block perpendicular to the sliding direction of the sliding baffle, the side wall of the sliding baffle is provided with a waist-shaped hole for the sliding pin to be inserted, the sliding pin slides vertically and freely in the waist-shaped hole, and the outer side wall of the fixed seat is provided with a special-shaped groove for the sliding pin to be inserted, the special-shaped groove includes two oblique grooves and one straight groove, the two oblique grooves are respectively connected with the length direction of the straight groove, and the sliding pin slides freely in the straight groove and the two oblique grooves.

[0022] Through the above technical solution, when the sliding baffle moves horizontally, the sliding pin will slide from the inclined groove to the straight groove, so that the sliding pin drives the floating mounting block to move upward, thereby causing the cutting knife to protrude to the top of the sliding baffle. When the sliding pin slides in the straight groove, the cutting knife can cut the pancake-shaped dihydrate gypsum deposition layer. When the sliding baffle slides close to the push-pull cylinder, the sliding pin will slide from the straight groove to another inclined groove, causing the floating mounting block to move downward and the cutting knife to retract into the through groove.

[0023] Furthermore, the surface of the pressure plate is provided with a plurality of connecting grooves in the form of through holes, and a plurality of guide columns are vertically fixedly connected to the upper surface of the pressure plate. A sealing baffle is commonly sleeved on the plurality of guide columns, and a guide hole for the guide columns to pass freely is provided on the end surface of the sealing baffle. A plurality of sealing blocks are fixedly connected to the lower surface of the sealing baffle, and the sealing blocks and the connecting grooves form a sliding fit, and after the sealing blocks are engaged in the connecting grooves, the bottom surface of the sealing blocks is flush with the bottom surface of the pressure plate, a nut is sleeved on the upper end of the guide column, and a spring is sleeved around the periphery of the guide column, and the two ends of the spring in the direction of elastic force elastically press against the end surface of the nut and the upper surface of the sealing baffle respectively, and a plurality of mounting openings are provided on the end surface of the pressure plate, and a ceramic membrane is installed in the mounting opening, and the bottom surface of the ceramic membrane is flush with the bottom surface of the pressure plate.

[0024] Through the above technical scheme, when the pressure plate squeezes the suspension in the compacting bin, the resistance of the suspension to the pressure plate is relatively large, and then under the action of hydraulic resistance, the sealing block is lifted up, so that the sealing block is separated from the connecting groove, and then the water in the suspension can seep out from the connecting groove. When the pressure plate contacts the dihydrate gypsum deposition layer, the water content in the dihydrate gypsum deposition layer is reduced, so that the hydraulic resistance of the sealing block is reduced, and the water in the dihydrate gypsum deposition layer will seep out from the ceramic membrane. At the same time, the ceramic membrane can block the dihydrate gypsum, thereby further reducing the water content in the dihydrate gypsum deposition layer. In addition, in the initial stage of the pressure plate squeezing the suspension, the water in the suspension can seep out from the connecting groove and will not exert a large pressure on the ceramic membrane, thereby avoiding damage to the ceramic membrane due to large resistance.

[0025] Furthermore, a rotating arm is rotatably sleeved on the periphery of the connecting sleeve, an upper wedge block is fixedly connected to the lower surface of the rotating arm, a lower wedge block is fixedly connected to the upper surface of the sealing baffle, a fixed shaft is horizontally fixedly connected to the upper surface of the rotating arm, a ball is rotatably embedded in the fixed shaft at one end away from the rotating arm, a rolling groove for the ball to engage is formed on the inner wall of the compaction bin, and the rolling grooves include a first vertical rolling groove, an inclined rolling groove and a second vertical rolling groove connected end to end from top to bottom, and the ball rolls freely in the first vertical rolling groove, the inclined rolling groove and the second vertical rolling groove.

[0026] Through the above technical solution, when the pressure plate contacts or approaches the dihydrate gypsum deposition layer, the ball will roll from the first vertical rolling groove to the inclined rolling groove, so that the ball drives the rotating arm to rotate a fixed angle, so that the upper wedge block and the lower wedge block slide relative to each other, so that the upper wedge block presses downward against the lower wedge block, and the sealing baffle moves downward, so that the sealing block re-engages in the connecting groove, so that the bottom surface of the pressure plate is flush, so that when the dihydrate gypsum deposition layer is pressed, the dihydrate gypsum deposition layer will not enter the connecting groove.

[0027] A method for producing regenerated gypsum using solid waste, applied to the regenerated gypsum production device as described above, comprising:

[0028] The solid waste is put into the feeding port and enters the crushing bin. After being crushed, the solid waste falls into the transition bin and then into the compaction bin.

[0029] After the crushed solid waste enters the compaction bin, it comes into contact with the water in the compaction bin, and the water dissolves the crushed solid waste, so that the dihydrate gypsum in the solid waste dissolves with the water to form a dihydrate gypsum suspension;

[0030] After the dissolution is completed, the suspension is allowed to stand and stratify, and the dihydrate gypsum is deposited at the bottom of the suspension. The compaction drive unit drives the pressing plate to move downward, and causes the pressing plate to engage in the compaction bin, thereby generating pressure on the suspension in the compaction bin. The water in the upper layer of the suspension will pass through the water seepage unit and enter the space surrounded by the upper surface of the pressing plate and the compaction bin. When the pressing plate contacts the dihydrate gypsum deposition layer, the dihydrate gypsum deposition layer will be squeezed by the pressing plate, and the water in the dihydrate gypsum deposition layer will gradually be discharged by the water seepage unit, thereby causing the pressing plate to press the dihydrate gypsum deposition layer into a cake shape and reduce the water content in the dihydrate gypsum deposition layer.

[0031] After the pressing is completed, the sliding baffle moves and makes the discharge port and the inner cavity of the compaction bin connected, so that the dihydrate gypsum pressed into a cake shape will fall from the discharge port into the dehydration bin below, and the dehydration bin will heat and dehydrate the dihydrate gypsum to finally obtain recycled gypsum.

[0032] Through the above technical solution, the dihydrate gypsum deposition layer is compacted by the pressing plate so that the dihydrate gypsum deposition layer is pressed into a cake shape, which reduces the water content of the dihydrate gypsum deposition layer, shortens the subsequent heating and dehydration time, and improves the production and processing efficiency of recycled gypsum.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present invention provides a pressing plate and a compaction driving unit, and the compaction driving unit drives the pressing plate to move in the compaction bin, and the pressing plate generates pressure on the dihydrate gypsum deposition layer in the compaction bin, so that the dihydrate gypsum deposition layer is squeezed into a cake shape, thereby reducing the water content of the dihydrate gypsum deposition layer. In the subsequent heating and dehydration, the dehydration time of the dihydrate gypsum is shortened, thereby improving the regeneration processing efficiency of the regenerated gypsum. In addition, since the dihydrate gypsum is compacted, the volume is relatively fixed, which is convenient for collection;

[0035] 2. The present invention provides a floating mounting block and a cutter, so that when the sliding baffle moves horizontally, the cutter lifting unit drives the floating mounting block to move upward, so that the cutter protrudes to the top of the sliding baffle, and the cutter can cut the pancake-shaped dihydrate gypsum, so that the dihydrate gypsum is cut into multiple parts, so that when the dihydrate gypsum is heated and dehydrated, the heating area is larger, thereby improving the dehydration efficiency of the dihydrate gypsum;

[0036] 3. The present invention is provided with a rotating arm, a ball and a rolling groove.

[0056] Working principle of the present invention:

[0057] Solid waste crushing: connect the external power supply and start the motor 3. The output shaft of the motor 3 drives the gear reducer 2 to rotate. The gear reducer 2 drives the two crushing tooth rollers 13 to rotate synchronously in the opposite direction. Specifically, Figure 4As shown, the left crushing tooth roller 13 rotates clockwise, while the right crushing tooth roller 13 rotates counterclockwise, and then a proper amount of solid waste is put into the feeding port 1, and the solid waste falls into the crushing bin 4 from the feeding port 1, and the solid waste is squeezed and crushed by the two crushing tooth rollers 13, so that the volume of the solid waste is reduced, and then falls onto the falling material inclined plate 14, and under the action of gravity, the solid waste will slide along the falling material inclined plate 14 to the falling material channel, and then fall into the transition bin 5, and further, a vibrating screen can be installed in the crushing bin 4, and the vibrating screen is used to screen the crushed solid waste falling from the falling material channel, so that the solid waste with a smaller volume falls into the transition bin 5;

[0058] Dissolution: The solid waste falling into the transition bin 5 will then enter the compaction bin 6, into which a suitable amount of water is pre-delivered, and the dihydrate gypsum in the solid waste will dissolve with the water to form a dihydrate gypsum suspension with a high concentration;

[0059] Compacting and dehydrating: After the dissolution is completed, the hydraulic cylinder 15 is started, and the piston rod of the hydraulic cylinder 15 is extended and drives the pressing plate 19 to move downward, so that the pressing plate 19 is engaged in the compacting bin 6. When the pressing plate 19 squeezes the suspension in the compacting bin 6, the resistance of the suspension to the pressing plate 19 is relatively large, and then under the action of the hydraulic resistance, the sealing block 26 overcomes the elastic supporting force of the spring 32 on the sealing baffle 24 and is lifted up, so that the sealing block 26 is separated from the connecting groove, and then the water in the suspension can seep out of the connecting groove. At this time, the force of the dihydrate gypsum on the ceramic membrane 25 is relatively small, so that the ceramic membrane 25 is less damaged, and at this time, the spring 32 is compressed by the sealing baffle 24 to accumulate elastic potential energy;

[0060] As the pressing plate 19 moves downward, the ball 35 will be engaged in the first vertical rolling groove 27 and roll in the first vertical rolling groove 27. At this time, since the ball 35 can roll vertically in the first vertical rolling groove 27, the pressing plate 19 and the sealing baffle 24 can move relative to each other, that is, when subjected to hydraulic resistance, the sealing baffle 24 can move upward relative to the pressing plate 19, so that the water in the dihydrate gypsum suspension can seep out from the connecting groove and enter the space surrounded by the upper surface of the pressing plate 19 and the inner wall of the compacting bin 6. In addition, at this time, the lower wedge block 34 moves upward, and the inclined surface of the upper wedge block 38 and the inclined surface of the lower wedge block 34 are counteracted.

[0061] When the pressing plate 19 approaches or contacts the dihydrate gypsum deposition layer, the ball 35 will roll from the first vertical rolling groove 27 to the inclined rolling groove 28, so that the ball 35 will drive the rotating arm 37 to rotate. When the rotating arm 37 rotates, it will drive the upper wedge block 38 to move relative to the lower wedge block 34, so that the inclined surface of the upper wedge block 38 and the inclined surface of the lower wedge block 34 slide relative to each other, so that the lower wedge block 34 will drive the sealing baffle 24 to move downward, thereby causing the sealing block 26 to re-engage to In the connecting groove, the bottom surface of the pressing plate 19 is flat. At this time, as the pressing plate 19 continues to move downward, the pressing plate 19 squeezes the dihydrate gypsum deposition layer. During the squeezing, the dihydrate gypsum deposition layer will be compacted, and the water in the dihydrate gypsum deposition layer will seep out from the ceramic membrane 25. When the pressing plate 19 continues to move downward, the ball 35 will roll from the inclined rolling groove 28 to the second vertical rolling groove 29, so that the lower surface of the sealing baffle 24 remains in contact with the upper surface of the pressing plate 19.

[0062] Blanking: After being pressed into a pancake shape, the piston rod of the hydraulic cylinder 15 stops moving, and then the cylinder rod of the push-pull cylinder 9 shortens and drives the sliding baffle 10 to move in the direction adjacent to the push-pull cylinder 9, thereby causing the sliding baffle 10 to slide in the sliding groove. When the sliding baffle 10 moves horizontally, the sliding pin 22 will slide from an inclined groove 17 away from the push-pull cylinder 9 to the straight groove 18, so that the sliding pin 22 drives the floating mounting block 23 to move upward, thereby causing the cutter 20 to protrude to the top of the sliding baffle 10, and the sliding pin 22 slides in the straight groove 18 toward the push-pull cylinder 9. When the sliding baffle 10 moves, the cutter 20 can cut the dihydrate gypsum deposit layer in a cake shape. When the sliding baffle 10 slides close to the push-pull cylinder 9, the sliding pin 22 will slide from the straight groove 18 to another inclined groove 17, so that the floating mounting block 23 moves downward and the cutter 20 is retracted into the through groove. After the sliding baffle 10 slides into place, the lower side of the compaction bin 6 is completely open, and the dihydrate gypsum cut into multiple parts will fall into the dehydration bin 8, and the heating device in the dehydration bin 8 will heat and dehydrate the dihydrate gypsum, and after heating and dehydration, the regenerated gypsum is obtained;

[0063] Reset: The piston rod of the hydraulic cylinder 15 is shortened and drives the pressure plate 19 to move upward, so that the ball 35 rolls from the second vertical rolling groove 29 to the inclined rolling groove 28, so that the ball 35 drives the rotating arm 37 to rotate in the opposite direction, thereby causing the inclined surface of the upper wedge block 38 and the inclined surface of the lower wedge block 34 to slide relative to each other in the opposite direction. As the pressure plate 19 continues to move upward, the ball 35 rolls from the inclined rolling groove 28 to the first vertical rolling groove 27. At this time, the pressure plate 19 and the sealing baffle 24 can move longitudinally relative to each other, and the elastic potential energy accumulated in the spring 32 is released, thereby causing the sealing baffle 24 and the pressure plate 19 to move relative to each other. The upper surfaces of the push-pull cylinders 9 are kept in a state of abutment with each other, and the cylinder rod of the push-pull cylinder 9 is extended, so that the sliding baffle 10 moves in the opposite direction, so that the sliding baffle 10 is re-engaged in the sliding groove, and the sliding pin 22 slides from an inclined groove 17 adjacent to the push-pull cylinder 9 to the straight groove 18, and then slides from the straight groove 18 to another inclined groove 17, so that the sliding baffle 10 closes the lower side opening of the compacting bin 6, and the blade 20 can be retracted into the through groove, thereby completing the resetting of each component, and then after repeated regeneration gypsum operations, the water in the transition bin 5 is pumped out and collected through the water inlet 12.

8. A method for producing regenerated gypsum using solid waste, applied to the regenerated gypsum production device according to claim 1, characterized in that: include: Solid waste is fed into a feeding port (1) and enters a crushing bin (4); after being crushed, the solid waste falls into a transition bin (5) and then into a compacting bin (6); After the pulverized solid waste enters the compacting bin (6), it comes into contact with water in the compacting bin (6), and the water dissolves the pulverized solid waste, so that the dihydrate gypsum in the solid waste dissolves with the water to form a dihydrate gypsum suspension; After the dissolution is completed, the suspension is allowed to stand and separate into layers, and the dihydrate gypsum is deposited at the bottom of the suspension. The compaction drive unit drives the pressing plate (19) to move downward, and causes the pressing plate (19) to engage with the compaction bin (6), thereby generating pressure on the suspension in the compaction bin (6).
