Description

Technical Field

[0001] This invention relates to the field of soil remediation equipment technology, and in particular to a mixing and stirring device for remediating soil pollution. Background Technology

[0002] Mixing and stirring is a common remediation technique for soil pollution. By mixing soil remediation agents with contaminated soil, the decomposition and degradation of pollutants are promoted, thereby achieving the purpose of soil remediation and environmental restoration. Before soil remediation, the soil needs to be crushed first. After crushing, soil remediation agents are added and mixed, and then stirred and stirred. After the soil remediation agents and the soil to be remediated are mixed, the mixture is discharged, thus completing the remediation of contaminated soil.

[0003] However, when breaking up soil, conventional crushing rollers are generally used. Due to the influence of the shape of the crushing blades and the operating status, the crushed soil may not be completely broken up, which will affect the mixing effect with the soil remediation agent later. At the same time, crushing the soil before adding the soil remediation agent will result in the soil remediation agent and the soil to be remediated being distributed in a regional pattern, which will increase the difficulty of mixing the two later and affect the mixing effect. Summary of the Invention

[0004] Therefore, it is necessary to provide this technical solution to address the problem that incomplete soil fragmentation and the regional distribution of soil remediation agents and soil to be remediated increase the difficulty of mixing the two later and affect the mixing effect.

[0005] A mixing and stirring device for remediating soil pollution, comprising:

[0006] A mixing mechanism includes a fixed frame, a conveyor belt, a mixing tank, a first motor, and a mixing rod. The conveyor belt is located below the fixed frame. The mixing tank is fixedly connected to the top of the fixed frame, and the first motor is installed at one end of the mixing tank.

[0009] In one embodiment, the feeding mechanism further includes a five-way pipe, an air supply pipe, a feed pipe, and a material tank. A third cylinder is provided between four ends of the five-way pipe and the corresponding first cylinder. A third piston plate is provided on the inner wall of the third cylinder. The other end of the third piston plate passes through the third cylinder and extends into the first cylinder. The feed pipe is inclined and connected to the outer wall of the housing. The air supply pipe is located between the remaining end of the five-way pipe and the feed pipe. A guide pipe is provided between the material tank and the feed pipe. A fourth spring is fixedly connected to one end of the inner wall of the feed pipe. A fourth piston plate is fixedly connected to the other end of the fourth spring. A fifth piston plate is fixedly connected to the other end of the fourth piston plate.

[0010] In one embodiment, the inner wall of the roller is fixedly connected to twelve guide frames arranged in a ring, the second piston plate passes through the guide frames, the inner wall of the guide frames is provided with a plurality of movable plates that match the dividing blades, a second spring is fixedly connected between the movable plates and the dividing blades, and two third springs are fixedly connected between the movable plates and the guide frames.

[0011] In one embodiment, the mixing mechanism further includes four sealing arc plates. The surface of the mixing tank is provided with multiple filter holes. The outer wall of the mixing tank is provided with a movable groove that matches the sealing arc plates. The sealing arc plates are located in the movable grooves, and a fifth spring is fixedly connected between the sealing arc plates and the inner wall of the movable grooves. One end of each of the sealing arc plates is fixedly connected with a round rod. The other end of the round rod passes through the mixing tank and is fixedly connected with a connecting arc plate. The other end of the mixing rod passes through the mixing tank and is provided with a toggle rod. A storage frame is fixedly connected to the inner side of the connecting arc plate. A sixth spring is fixedly connected to the inner bottom wall of the storage frame. The other end of the sixth spring is fixedly connected with a telescopic rod. The top end of the telescopic rod passes through the storage frame and contacts the toggle rod.

[0012] In one embodiment, a plurality of inclined grooves are provided on one side of the telescopic rod, and an inclined block is provided on the inner wall of one of the inclined grooves. A seventh spring is fixedly connected between the inclined block and the storage frame. An operating rod is fixedly connected to one side of the inclined block, and the other end of the operating rod passes through the seventh spring and the storage frame in sequence.

[0013] In one embodiment, a U-shaped locking seat is fixedly connected to the other end of the mixing tank. Locking blocks are fixedly connected to both sides of the inner wall of the U-shaped locking seat. The locking blocks have a triangular cross-section and are made of rubber material.

[0014] In one embodiment, a one-way bearing is provided between the actuating rod and the mixing rod, and four arc-shaped grooves are provided at the other end of the mixing tank, in which the round rod slides.

[0015] In one embodiment, a sealed bearing is provided at the connection between the gas supply pipe and the five-way pipe, and the angle between the feed pipe and the horizontal plane is sixty degrees.

[0016] In one embodiment, a strip groove is provided on the inner side of the crushing blade, and the dividing blade slides within the strip groove.

[0017] The aforementioned feeding mechanism utilizes the interaction of the crushing blades, dividing blades, and dividing cutters to achieve vertical crushing of contaminated soil while automatically crushing it laterally during its reciprocating cycle. This results in better crushing of the contaminated soil, preventing incomplete crushing and improving the mixing effect of the contaminated soil and soil remediation agent in the later stages. Simultaneously, within a small operating cycle, the two horizontal dividing blades act as a sealing mechanism, causing the crushed soil to fall while isolating the uncrushed soil above. During this process, the soil remediation agent is automatically added, ensuring that it is added into the interior of the crushed soil while feeding. This prevents the soil remediation agent and the soil to be remediated from being distributed in a regional pattern, reducing the difficulty of mixing the two later and improving their mixing effect.

[0018] The aforementioned mixing mechanism can switch the state of the mixing tank by using the forward and reverse rotation of its first motor. It performs simple mixing in the early stage, and after mixing is completed, it runs in reverse to enhance the mixing effect. At the same time, the filter holes will automatically leak out, and the contaminated soil that meets the specifications and has been treated will automatically enter the fixed frame and be automatically discharged by the conveyor belt, ensuring the effectiveness of soil pollution treatment.

[0040] The following is combined Figures 1-13 The present invention describes a mixing and stirring device for treating soil pollution.

[0041] In one embodiment, a mixing and stirring device for remediating soil pollution includes:

[0042] The mixing mechanism 100 includes a fixed frame 110 and a conveyor belt 120. The conveyor belt 120 is located below the fixed frame 110. A mixing tank 130 is fixedly connected to the top of the fixed frame 110. A first motor 140 is fixedly installed at one end of the mixing tank 130. A mixing rod 150 is fixedly connected to the output shaft of the first motor 140. The other end of the mixing rod 150 extends into the mixing tank 130.

[0043] The feeding mechanism 200 includes a housing 210, a feeding frame 220, and a discharge hopper 230.

[0044] A hopper 230 is positioned between a mixing tank 130 and a housing 210. A feed frame 220 is fixedly connected to the top of the housing 210. Two rollers 240 are rotatably connected to the inner wall of the housing 210, and the ends of the rollers 240 penetrate the housing 210 and are fixedly connected to two meshing gears 242. One end of one gear 242 is fixedly connected to a grooved wheel 243. The output shaft of a second motor 244 is fixedly connected to a turntable 245 that cooperates with the grooved wheel 243. The surface of the rollers 240 is fixedly connected with evenly distributed crushing agents. The crusher 241 and the other end of the roller 240 pass through the housing 210 and are provided with a main pipe 250 arranged in a ring. One end of the main pipe 250 passes through the roller 240 and is connected to three second cylinders 255. The inner wall of the second cylinder 255 is provided with a second piston plate 256. The other side of the second piston plate 256 passes through the second cylinder 255 and is fixedly connected to a dividing blade 257. The dividing blade 257 passes through the roller 240 and extends into the crusher 241. The inner recess of the dividing blade 257 is provided with dividing blades 259.

[0045] like Figure 1 , Figure 3 and Figure 8 The feeding mechanism 200 also includes four first cylinders 251 arranged in a ring and fixedly connected to the other end of the roller 240. The first cylinders 251 are connected to the corresponding main pipes 250. A first spring 252 is fixedly connected to one end of the inner wall of the first cylinder 251. A first piston plate 253 is fixedly connected to the other end of the first spring 252. A trigger rod 254 is fixedly connected to the other end of the first piston plate 253. A trigger plate 211 is fixedly connected to the middle of one side of the housing 210. The other end of the trigger rod 254 passes through the first cylinder 251.

[0046] In this embodiment, during the operating cycle, the second motor 244 drives the actuating disk 245 to rotate four times, the grooved wheel 243 and the circular roller 240 to rotate one full rotation, and the first cylinder 251 and the dividing blade 257 are also grouped into four groups. Correspondingly, when the circular roller 240 rotates one-quarter, the corresponding trigger rod 254 will contact the trigger plate 211. The corresponding trigger rod 254 is in a horizontal state of the housing 210. The trigger rod 254 drives the first piston plate 253 to move, the first spring 252 is bent by force, and the gas inside the first cylinder 251 will enter the second cylinder 255 from the main pipe 250, driving the dividing blade 257 and the dividing blade 259 to run automatically without separate operation. The automated operation makes its operation more reasonable.

[0047] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The feeding mechanism 200 also includes a five-way pipe 267, an air supply pipe 266, a feed pipe 260, and a material tank 264. A third cylinder 269 is provided between four ends of the five-way pipe 267 and the corresponding first cylinder 251. A third piston plate 2610 is provided on the inner wall of the third cylinder 269. The other end of the third piston plate 2610 passes through the third cylinder 269 and extends into the first cylinder 251. The feed pipe 260 is inclined and connected to the outer wall of the housing 210. The air supply pipe 266 is located between the remaining end of the five-way pipe 267 and the feed pipe 260. A guide pipe 265 is provided between the material tank 264 and the feed pipe 260. A fourth spring 261 is fixedly connected to one end of the inner wall of the feed pipe 260. A fourth piston plate 262 is fixedly connected to the other end of the fourth spring 261. A fifth piston plate 263 is fixedly connected to the other end of the fourth piston plate 262.

[0048] In this embodiment, when the first piston plate 253 moves to a predetermined position, it will squeeze the corresponding third piston plate 2610 into the third cylinder 269. Gas enters the feed pipe 260 from the five-way pipe 267 and the gas delivery pipe 266. The gas pushes the fourth piston plate 262 and the fifth piston plate 263 to move, spraying the powdered soil remediation agent between them into the box 210. It should be noted that the fourth piston plate 262 and the fifth piston plate 263 form a storage area in normal operation, realizing the quantitative addition of soil remediation agent, reducing the error of addition. After the external force disappears, the fourth spring 261 can play the role of automatic reset. The two horizontal dividing blades 257 will block, so that the broken soil falls and the unbroken soil above is isolated. During this process, the soil remediation agent is automatically added to the interior of the broken soil at the same time as feeding, avoiding the soil remediation agent and the soil to be remediated from being distributed in a regional manner, reducing the difficulty of mixing the two later and improving their mixing effect.

[0049] like Figure 3 , Figure 4 , Figure 8 and Figure 9 A sealed bearing 268 is installed at the connection between the gas supply pipe 266 and the five-way pipe 267. The angle between the feed pipe 260 and the horizontal plane is 60 degrees. The sealed bearing 268 can prevent the gas supply pipe 266 from being affected by the rotational force of the five-way pipe 267, thus protecting the gas supply pipe 266 and extending its service life.

[0050] like Figure 5 and Figure 6 The inner side of the crusher 241 is provided with a strip groove, and the dividing blade 257 slides in the strip groove.

[0051] In this embodiment, the strip groove can limit the cutting blade 257 and improve the sealing effect.

[0052] like Figure 6 and Figure 7 The inner wall of the roller 240 is fixedly connected with twelve guide frames arranged in a ring. The second piston plate 256 passes through the guide frames. The inner wall of the guide frames is provided with multiple movable plates that match the dividing blade 259. A second spring 258 is fixedly connected between the movable plate and the dividing blade 259. Two third springs 2510 are fixedly connected between the movable plate and the guide frame.

[0053] In this embodiment, the cooperation between the guide frame and the second cylinder 255 can form a relatively closed area, preventing soil from entering the roller 240 and ensuring the normal operation of the device.

[0054] like Figure 10 , Figure 11 , Figure 12and Figure 13 The mixing mechanism 100 also includes four sealing arc plates 160. The surface of the mixing tank 130 is provided with multiple filter holes 131. The outer wall of the mixing tank 130 is provided with a movable groove 132 that matches the sealing arc plates 160. The sealing arc plates 160 are located in the movable groove 132. A fifth spring 161 is fixedly connected between the sealing arc plates 160 and the inner wall of the movable groove 132. One end of each of the multiple sealing arc plates 160 is fixedly connected with a round rod 162. The other end of the round rod 162 passes through the mixing tank 130 and is fixedly connected with a connecting arc plate 163. The other end of the mixing rod 150 passes through the mixing tank 130 and is provided with a toggle rod 151. A storage frame 164 is fixedly connected to the inner side of the connecting arc plate 163. A sixth spring 165 is fixedly connected to the inner bottom wall of the storage frame 164. The other end of the sixth spring 165 is fixedly connected with a telescopic rod 166. The top end of the telescopic rod 166 passes through the storage frame 164 and contacts the toggle rod 151.

[0055] In this embodiment, under the action of the one-way bearing 152, the mixing rod 150 drives the actuating rod 151 to rotate. The actuating rod 151, with its arc shape, drives the telescopic rod 166, the storage frame 164, the connecting arc plate 163, the round rod 162, and the sealing arc plate 160 to rotate synchronously. The round rod 162 on the side will enter the locking seat 134, and the locking block 135 inside the seat will limit the round rod 162 on the side. At this time, the telescopic rod 166, the storage frame 164, the connecting arc plate 163, the round rod 162, and the sealing arc plate 160 will no longer rotate, and the actuating rod 151 will continue to rotate. The actuating rod 151 will drive the telescopic rod 166 to move downward, and during the downward movement, the inclined block 169 will be in the seventh spring 168. Under the action, the automatic deformation latch is engaged in the corresponding inclined groove 167, ensuring that the telescopic rod 166 can move downward in one direction, ensuring that the actuating rod 151 will not contact the telescopic rod 166 during the second rotation. The sealing arc plate 160 moves in the movable groove 132, exposing the filter hole 131. With the cooperation of the reverse rotating mixing rod 150 and the filter hole 131, the treated soil will fall from the filter hole 131 onto the conveyor belt 120, and the treated soil will be transported out. While enhancing the mixing effect, the filter hole 131 will automatically leak out. The contaminated soil that meets the specifications and is treated will automatically enter the fixed frame 110 and be automatically discharged through the conveyor belt 120, ensuring the effect of soil pollution treatment.

[0056] like Figure 12 and Figure 13 The telescopic rod 166 has multiple inclined slots 167 on one side. One of the inclined slots 167 has an inclined block 169 on its inner wall. A seventh spring 168 is fixedly connected between the inclined block 169 and the storage frame 164. An operating rod 1610 is fixedly connected to one side of the inclined block 169. The other end of the operating rod 1610 passes through the seventh spring 168 and the storage frame 164 in sequence.

[0057] In this embodiment, the telescopic rod 166, storage frame 164, connecting arc plate 163, round rod 162 and sealing arc plate 160 will no longer rotate, the actuating rod 151 will continue to rotate, the actuating rod 151 will drive the telescopic rod 166 to move downward, and during the downward movement, the inclined block 169 will automatically deform and engage in the corresponding inclined groove 167 under the action of the seventh spring 168, ensuring that the telescopic rod 166 can move downward in one direction, and automatically realize the switching of the state of the mixing tank 130.

[0058] like Figure 12 The other end of the mixing tank 130 is fixedly connected to a U-shaped locking seat 134. Locking blocks 135 are fixedly connected to both sides of the inner wall of the U-shaped locking seat 134. The cross-section of the locking blocks 135 is triangular and made of rubber. By utilizing the properties and shape of the rubber material, the round rod 162 that enters the tank can be locked, ensuring the stability of the arc-shaped sealing plate when locked.

[0059] A one-way bearing 152 is provided between the actuating rod 151 and the mixing rod 150. Four arc-shaped grooves 133 are provided at the other end of the mixing tank 130, and the round rod 162 slides in the arc-shaped grooves 133.

[0060] Working principle: The contaminated soil to be treated is placed into the feed frame 220. The second motor 244 is started. The second motor 244 drives the eccentrically positioned actuating disc 245 to rotate the grooved wheel 243. The grooved wheel 243 drives one of the gears 242 to rotate. Under the action of the two meshing gears 242, the two rollers 240 rotate relative to each other. The crushing blades 241 on the surface of the two rollers 240 crush the soil. One rotation of the actuating disc 245 is one cycle. The grooved wheel 243 travels one-quarter of the way. At this time, the rollers... 240 also operates at one-quarter speed. When the roller 240 rotates one-quarter, the corresponding trigger rod 254 will contact the trigger plate 211. The corresponding trigger rod 254 is in a horizontal state in the housing 210. The trigger rod 254 drives the first piston plate 253 to move, the first spring 252 bends under force, and the gas inside the first cylinder 251 will enter the second cylinder 255 from the main pipe 250. The second piston plate 256 will drive the dividing blade 257 into the strip groove of the crusher 241. Since there are three dividing blades 257 in each operating cycle, the additional... Figure 6The exploded view shows four groups in total. The upper dividing blade 257 of the three dividing blades 257 is horizontal. The two horizontal dividing blades 257 and the numerous crushing blades 241 work together to separate the soil before and after crushing. Additionally, two dividing blades 259, under the action of the second piston plate 256, the second spring 258, and the third spring 2510, further cut the soil during crushing. During this cycle, when the first piston plate 253 moves to a predetermined position, the first piston... Plate 253 will squeeze the corresponding third piston plate 2610 into the third cylinder 269. Gas enters into the feed pipe 260 from the five-way pipe 267 and the gas delivery pipe 266. The gas pushes the fourth piston plate 262 and the fifth piston plate 263 to move, spraying the powdered soil remediation agent between them into the box 210, realizing the automatic addition of soil remediation agent in one cycle. The rotation of the second motor 244 realizes the cyclic reciprocating operation of the two rollers 240, which can break up the contaminated soil and add soil remediation agent in layers.

[0061] After the initial treatment, the crushed contaminated soil and soil remediation agent enter the mixing tank 130. The first motor 140 is started, and its forward rotation drives the mixing rod 150 to mix the contents of the mixing tank 130. After mixing, the first motor 140 reverses, and under the action of the one-way bearing 152, the mixing rod 150 drives the actuating rod 151 to rotate. The actuating rod 151, with its arc shape, drives the telescopic rod 166, the storage frame 164, the connecting arc plate 163, the round rod 162, and the sealing arc plate 160 to rotate synchronously. The round rod 162 on the side enters the locking seat 134, and the locking block 135 inside the locking seat limits the round rod 162 on the side. At this time, the telescopic rod 166, the storage frame 164, the connecting arc plate 163, the sealing arc plate 164, the sealing arc plate 165, and the sealing arc plate 160 rotate synchronously. Plate 163, round rod 162, and sealing arc plate 160 will no longer rotate, while the actuating rod 151 will continue to rotate. The actuating rod 151 will drive the telescopic rod 166 to move downwards, and during the downward movement, the inclined block 169 will automatically deform and engage in the corresponding inclined groove 167 under the action of the seventh spring 168, ensuring that the telescopic rod 166 can move downwards in one direction. This ensures that the actuating rod 151 will not contact the telescopic rod 166 again during the second rotation. The sealing arc plate 160 moves in the movable groove 132, exposing the filter hole 131. With the cooperation of the reverse rotating mixing rod 150 and the filter hole 131, the treated soil will descend from the filter hole 131 onto the conveyor belt 120, and the treated soil will be transported out.
