Description

Technical Field

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

[0002] Currently, soil remediation often uses remediation agents, and these agents are often mixed using mixing instruments.

[0003] Currently, a soil remediation agent mixing instrument, announced in Chinese Patent No. CN219984446U, includes a mixing box and a positioning plate. The mixing box has a mixing placement mechanism fixedly installed on both sides of the upper outer wall. The inner wall of the mixing placement mechanism has a rotatable opening mechanism. The positioning plate is fixedly installed on the upper inner wall of the mixing box. A drive motor is fixedly installed on the upper inner wall of the positioning plate. The output end of the drive motor is provided with a rotating shaft. A stirring mechanism is provided on the lower outer wall of the rotating shaft.

[0004] The aforementioned methods use adhesive paper or plastic graduated plates as measurement markers. These plates are easily worn down or deformed by pesticide residue, humidity, or repeated friction, leading to unclear graduations and significant reading errors. Furthermore, the mixing process relies on manual visual reading of the graduations and manual operation. The operator's skill level and reading deviations directly affect the mixing accuracy, resulting in poor consistency in pesticide proportions during batch mixing. Therefore, we propose a precise mixing device for soil remediation agents to address these problems. Summary of the Invention

[0034] Based on the above, and referring to Figure 2 , 3 The extraction mechanism includes a sealing plate 107, a drive rod 108, a baffle 206, and a piston seat 109.

[0036] Based on the above, and referring to Figure 4 A control box 401 is fixedly installed on the top of the mixing tank 101. Two symmetrically arranged guide rods 202 are fixedly installed on the top of the control box 401. The drive plate 203 is slidably fitted on the outside of the guide rods 202. The guide rods 202 limit and guide the drive plate 203 to ensure the smoothness of the lifting process of the drive plate 203 and avoid deviation and jamming.

[0037] Based on the above, and referring to Figure 5 The adjustment mechanism includes multiple sliding holes 301, a scale rod 302, an adjustment plate 303, a threaded hole 304, and an adjustment screw 305.

The bottom end of the adjustment screw 305 is rotatably connected to the top surface of the adjustment plate 303. A knob 306 is fixedly installed at the top end of the adjustment screw 305. By rotating the knob 306, the height of the adjustment plate 303 can be precisely adjusted, limiting the maximum upward stroke of the baffle 206, thereby controlling the amount of reagent extracted in a single operation.

[0038] Based on the above, and referring to Figure 3 A rotating shaft 407 is fixedly installed at the top of the rectangular rod 405. The rotating shaft 407 passes through the control box 401 and is rotatably mounted on the top of the drive plate 203, so that the rectangular rod 405 can rise and fall synchronously with the drive plate 203, and can also rotate independently, realizing the combination of the up-and-down reciprocating motion and the circumferential rotation motion of the stirring structure.

[0039] Based on the above, and referring to Figure 6 , 7An annular rotating plate 501 is rotatably mounted on the inner wall of the mixing tank 101. Multiple evenly distributed fixing rods 502 are fixedly connected between the annular rotating plate 501 and the rotating seat 403. Two symmetrically arranged connecting rods 503 are fixedly connected to the bottom of the annular rotating plate 501. Scrapers 504, which fit against the inner wall of the mixing tank 101, are fixedly mounted on the outer side of the connecting rods 503 and can rotate synchronously with the annular rotating plate 501 to scrape away residual material from the tank wall in real time. The adjustable stirring mechanism includes multiple connecting shafts 505, multiple connecting shafts 508, stirring rods 506, elongated holes 507, and limiting blocks 509. One connecting shaft 505 is fixed at equal intervals at the ends of two connecting rods 503 that are far apart from each other. Multiple connecting shafts 508 are fixed at equal intervals on the front and rear sides of the rectangular rod 405. One end of the stirring rod 506 is rotatably fitted onto the outside of the corresponding connecting shaft 505. An elongated hole 507 is provided on the front side of the stirring rod 506, and the connecting shafts 508 slide through the corresponding elongated hole 507. Limiting blocks 509 are fixedly installed at the ends of both the connecting shafts 505 and 508. The stirring rod 506 is driven to swing adaptively by the lifting and lowering of the rectangular rod 405, so as to dynamically adjust the stirring radius and stirring range.

[0040] Based on the above, and referring to Figure 4 A drive motor 601 is fixedly installed on the inner wall of the top of the control box 401. The output shaft of the drive motor 601 is fixedly connected to a linkage shaft 602. The bottom end of the linkage shaft 602 is rotatably mounted on the top of the mixing tank 101. A drive gear 603 is fixedly mounted on the outside of the linkage shaft 602. A driven gear 604 is fixedly mounted on the outside of the rotating seat 403. The drive gear 603 and the driven gear 604 mesh with each other, and drive the rotating seat 403 to rotate continuously through gear meshing transmission.

[0041] Based on the above, and referring to Figure 1 A controller 7 is fixedly installed on the top of the mixing tank 101. The push rod motor 208 and the drive motor 601 are electrically connected to the controller 7. The controller 7 realizes the automated program control of the equipment and accurately controls the mixing ratio and mixing process. It should be noted that the controller 7 is a PLC controller 7, and the controller 7, push rod motor 208 and drive motor 601 can all be purchased from the market. The power supply method and circuit connection method are common knowledge to those skilled in the art, and can be known by those skilled in the art without creative effort. Moreover, the power supply method and circuit connection method are not within the protection scope of this solution, so they are not described in detail.

[0042] The working principle of this invention is as follows: Before operation, the operator rotates the knobs 306 of each adjustment mechanism in sequence, which drives the adjustment screw 305 to rotate and rise and fall vertically, accurately adjusting the height position of the adjustment plate 303. Combined with the scale of the scale rod 302, the maximum upward stroke of the baffle 206 is precisely limited, thereby matching the dosage of different agents and realizing independent quantitative adjustment of multiple agents.

[0043] The push rod motor 208 is activated by the controller 7 to perform periodic reciprocating extension and retraction operations. The output shaft of the push rod motor 208 drives the drive plate 203 to rise and fall vertically and smoothly along the guide rods 202 on both sides. When the drive plate 203 descends, it drives the drive rod 108 and piston seat 109 to move downward through the drive seat 205. The piston seat 109 descends along the inner wall of the piston cylinder 104 in a sealed manner, compressing the air in the lower chamber of the piston cylinder 104 to form positive pressure. At this time, the one-way valve inside the liquid extraction pipe 105 closes and the one-way valve inside the liquid injection pipe 106 opens, and the preset volume of medicine in the piston cylinder 104 is precisely pressed into the mixing tank 101. When the drive plate 203 returns to its original position, it pushes the baffle 206, drive rod 108, and piston seat 109 to move upward synchronously through the compression spring 207, so that the lower chamber of the piston cylinder 104 forms positive pressure. In a negative pressure vacuum environment, the one-way valve inside the injection pipe 106 is closed and the one-way valve inside the extraction pipe 105 is open. Under the action of negative pressure, the repair agent in the storage tank 103 is drawn into the piston cylinder 104 along the extraction pipe 105, completing a single quantitative replenishment. When the baffle 206 with less material is extracted at one time contacts the corresponding adjusting plate 303 first, when the drive plate 203 continues to move upward, this drive plate 203 can only compress the corresponding compression spring 207, and cannot drive the corresponding baffle 206 to move upward, thereby achieving the purpose of precise quantitative extraction of different agents. The push rod motor 208 continues to reciprocate, so that multiple repair agents can be continuously and accurately put into the mixing tank 101 according to the preset ratio, completely avoiding the problems of imbalance in the ratio of manual feeding and large feeding errors.

[0044] During the synchronous stage of drug formulation and feeding, the controller 7 starts the drive motor 601 to run continuously. The drive motor 601 drives the drive gear 603 to rotate at high speed through the linkage shaft 602. Utilizing the gear meshing transmission principle, the driven gear 604 and the rotating seat 403 rotate at a uniform speed as a whole. During the rotation of the rotating seat 403, on the one hand, the fixed rod 502 drives the annular rotating plate 501, the connecting rod 503, and the inner scraper 504 to rotate synchronously in the circumferential direction. This allows the scraper 504 to continuously scrape against the inner wall of the mixing tank 101, promptly removing the original drug solution and sediment adhering to the tank wall, eliminating material residue, and ensuring that all drugs participate in the mixing. On the other hand, the rotating seat 403, through the cooperation of the rectangular hole 404 and the rectangular rod 405, drives the rectangular rod 405, the bottom stirring blade 406, and the adjustable stirring mechanism to rotate in the circumferential direction as a whole.

[0045] Meanwhile, the rotating shaft 407 at the top of the rectangular rod 405 is rotatably mounted on the drive plate 203, and can move vertically in sync with the lifting and lowering action of the drive plate 203, driving the stirring blade 406 and the stirring mechanism to move up and down reciprocally. During operation, the lifting and lowering of the rectangular rod 405 will drive the connecting shaft 2 508 to slide along the elongated hole 507 of the stirring rod 506, driving multiple sets of stirring rods 506 to swing adaptively open or close with the connecting shaft 1 505 as the fulcrum, adjusting the stirring radius and stirring depth in real time. Together with the central stirring blade 406, a multi-level, all-round stirring flow field is formed from top to bottom and from inside to outside, effectively breaking the stratification and sedimentation of the agent, and greatly improving the mixing uniformity of various agents.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
