Description

Technical Field

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

[0002] Soil remediation is a crucial aspect of environmental governance. Adding remediation agents to contaminated soil is a key step in achieving soil harmlessness and resource recovery. Remediation agents, such as solidifying agents, stabilizing agents, oxidizing agents, and microbial agents, need to be thoroughly mixed in advance according to the specified proportions. Currently, most soil remediation agent mixing equipment on the market uses a horizontal mixing drum with a central mixing shaft to roughly mix the agents before spraying them into the soil through irrigation equipment.

[0003] Traditional single-shaft mixing devices, when rotating within the mixing drum, primarily mix chemical materials in the central area. Due to gaps between the mixing blades and the drum wall, and limited axial pushing capability of the chemicals, the chemicals near the drum wall and ends are difficult to agitate effectively, creating dead zones. This prevents sufficient contact between different chemical mixtures, severely impacting remediation efficacy. Therefore, a soil remediation chemical mixing device is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A soil remediation agent mixing device includes a frame assembly installed on top of an agent tank. The top of the frame assembly is equipped with a mixing part for mixing. The frame assembly serves as the support structure for the entire device, not only bearing the weight of the mixing part, but also achieving quick fixation to the agent tank through adjustable pull-out plates and snap-on plates, ensuring a stable and reliable mixing process. The frame assembly includes a horizontal plate, and retractable pull-out plates are inserted into the left and right sides of the horizontal plate through guide grooves. The ends of the pull-out plates are connected to buckles that are fastened to the rim of the medicine barrel. The pull-out plates can retract and move in the guide grooves of the horizontal plate and are fastened to the rim of the medicine barrel through the buckles, so as to achieve a tight connection between the device and the barrel. The stirring part includes a drive motor fixedly installed at the top of the horizontal plate. The shaft end of the drive motor passes through the horizontal plate and is connected and fixed to the rotating shaft. Two sets of mixing components are symmetrically arranged on the surface of the rotating shaft. A turning blade for accelerating stirring is provided at the end of the rotating shaft.

[0006] Preferably, the leaf-turning plate has a curved arc structure design, and rubber blocks are embedded in the side of the leaf-turning plate through movable grooves. The top of the rubber blocks is connected to a rubber plate, which is attached to the inner wall of the medicine tank. The curved arc structure of the leaf-turning plate can effectively push the medicine at the bottom upward. The rubber blocks use elasticity to make the rubber plate fit tightly against the inner wall of the medicine tank, scraping off the wall-mounted medicine during rotation and reducing residue.

[0007] Preferably, the mixing component includes a bushing fixed to the surface of the rotating shaft. U-shaped clips are installed on the left and right sides of the top of the bushing through slots, and an impeller for mixing the repair agent is connected to the outside of the U-shaped clips. The mixing component is fixed to the rotating shaft by the bushing, and the impeller is connected to the bushing by the U-shaped clips. When the rotating shaft rotates, it drives the impeller to rotate, generating centrifugal force to form a concave swirling flow field of the agent, which promotes the uniform mixing of multiple agents.

[0008] Preferably, the U-shaped card has card insert plates for snapping on both sides through movable slots. The inner end face of the card insert plate and the movable slot of the U-shaped card are provided with elastic support springs. The L-shaped horizontal plate end of the card insert plate can be embedded into the card slot on the inner wall of the bushing slot to ensure the stable docking of the U-shaped card and the bushing.

[0009] Preferably, a fixing screw is inserted into the surface of the horizontal plate through a threaded hole, and the end of the fixing screw abuts against the surface of the pull-out plate through a groove. The fixing screw is inserted into the surface of the horizontal plate through a threaded hole, and its end can abut against the inner wall of the groove of the pull-out plate to achieve locking and fixing of the pull-out plate.

[0010] Preferably, a toothed disc is rotatably mounted at the center of the horizontal plate, and an annular plate end is provided at the top of the toothed disc. The annular plate end is rotatably mounted on the inner wall of the horizontal plate through an annular groove. The surface of the toothed disc meshes with the toothed ends of the two pull-out plates through the teeth. The central through hole of the toothed disc avoids interference with the rotating shaft, ensuring that the two move independently.

[0011] Preferably, a ball end is embedded in the ball groove below the end of the toothed disc ring plate, and the ball end abuts against the inner wall of the ring groove of the horizontal plate. The ball end is embedded in the ball groove below the toothed disc ring plate and forms rolling friction with the ring groove of the horizontal plate, reducing the resistance when the toothed disc rotates and making the adjustment of the pull plate smoother.

[0012] This utility model has at least the following beneficial effects: 1. This utility model, by setting up a flapping plate and a rubber plate that can fit against the inner wall of the agent tank, scrapes and flips the agent on the tank wall and bottom during the mixing process, avoiding the mixing dead corners formed at both ends of the cylinder wall and cylinder body in traditional single-shaft mixing devices, ensuring that the remediation agent is fully mixed and improving the soil remediation effect. Through the combined design of the rotating shaft, blade shaft and flapping plate, a centrifugal concave vortex and bottom upward flow field are formed during the mixing process, which accelerates the axial and radial mixing of the agent, shortens the mixing time and improves work efficiency.

[0013] 2. This utility model, through the coordinated design of the pull-out plate, toothed disc and buckle plate, can flexibly adjust the fixed position of the frame assembly and the reagent tank, adapt to various tank opening sizes, enhance the equipment's versatility and on-site applicability, and adopts a modular design, such as a quick disassembly and assembly structure composed of U-shaped clips, clip inserts and springs, making the stirring components easy to disassemble, clean or replace, reducing maintenance costs and time.

[0014] 3. This utility model effectively reduces the amount of medicine adhering to the wall and residue by continuously scraping the barrel wall with a rubber plate during rotation, ensuring maximum utilization of the medicine and meeting environmental protection and economic requirements.

[0022] The U-shaped card 332 has card insert plates 334 for snapping on both sides through movable slots. The inner end face of the card insert plate 334 and the movable slot of the U-shaped card 332 are provided with elastic support springs 335.

[0023] A fixing screw 25 is inserted into the surface of the horizontal plate 21 through a threaded hole, and the end of the fixing screw 25 abuts against the surface of the pull-out plate 23 through a groove.

[0024] A toothed disc 22 is rotatably mounted at the center of the horizontal plate 21. The top of the toothed disc 22 is provided with an annular plate end, which is rotatably mounted on the inner wall of the horizontal plate 21 through an annular groove. The surface of the toothed disc 22 meshes with the toothed ends of the two pull-out plates 23 through teeth.

[0025] Below the ring plate end of the gear disc 22, a ball end is embedded in the ball groove, and the ball end abuts against the inner wall of the ring groove of the horizontal plate 21.

[0026] The frame assembly 2 serves as the supporting structure for the entire device, not only bearing the weight of the mixing section 3 but also achieving quick and reliable fixing to the reagent tank 1 via adjustable pull-out plates 23 and snap-on plates 24, ensuring a stable and reliable mixing process. The mixing section 3 is the core power component, providing rotational power through the drive motor 31 to drive the internal mixing section 3 to achieve reagent mixing. The pull-out plate 23 can extend and retract within the guide groove of the horizontal and vertical plates 21, and is fastened to the rim of the reagent tank 1 via the snap-on plates 24, achieving a tight connection between the device and the tank. This design allows the device to adapt to reagent tanks 1 of different diameters, improving the equipment's versatility and on-site adaptability.

[0027] The blade 34 has a curved structure, which can effectively push the bottom medicine upward; the rubber block 35 uses elasticity to make the rubber plate 36 fit tightly against the inner wall of the medicine tank 1, scraping off the wall-mounted medicine during rotation, reducing residue, and enhancing the turning effect of the bottom medicine, eliminating dead corners in the mixing; the mixing component 33 is fixed to the rotating shaft 32 by the bushing 331, and the blade shaft 333 is connected to the bushing 331 by the U-shaped clip 332. When the rotating shaft 32 rotates, it drives the blade shaft 333 to rotate, generating centrifugal force to form a concave swirling flow field of the medicine, promoting the uniform mixing of various medicines; the U-shaped clip 332 is connected to the bushing 331 through the slot, and the insert plate 334 is inserted into the slot on the inner wall of the bushing 331 under the action of the spring 335, realizing the quick installation and fixation of the blade shaft 333, which facilitates the disassembly, cleaning or replacement of the mixing part 3 and improves maintenance efficiency.

[0028] The insert plate 334 has an L-shaped structure. When the U-shaped card 332 is inserted into the slot of the bushing 331, the L-shaped horizontal end of the insert plate 334 can be embedded into the slot of the inner wall of the bushing 331, ensuring the stable connection between the U-shaped card 332 and the bushing 331. The fixing screw 25 is inserted into the surface of the horizontal plate 21 through the threaded hole, and its shaft end can abut against the inner wall of the groove of the pull plate 23 to lock and fix the pull plate 23, preventing displacement during the stirring process and ensuring operational safety.

[0029] A through hole is provided at the center of the gear disc 22 for the shaft 32 to pass through, so as to avoid mutual interference between the gear disc 22 and the shaft 32. The gear disc 22 meshes with the tooth ends of the two pull plates 23 through the teeth. When one pull plate 23 moves, the gear disc 22 rotates and drives the other pull plate 23 to move in the opposite direction at the same time, so as to realize the symmetrical adjustment of the two buckles 24, ensure that the device is centered and fixed, and avoid skew. The ball end is embedded in the ball groove under the ring plate of the gear disc 22, forming rolling friction with the ring groove of the horizontal plate 21, reducing the resistance when the gear disc 22 rotates, and making the adjustment of the pull plate 23 smoother.

[0030] Working principle: According to Figure 2 , Figure 3 and Figure 4 As shown, during use, the horizontal plate 21 is suspended above the medicine tank 1, and pulled by the buckle plate 24 at one end, the buckle plate 24 drives the pull plate 23 to move. At this time, affected by the teeth of the toothed disc 22 at the center position, the pull plates 23 on both sides of the toothed disc 22 can move relative to each other, and at the same time drive the toothed disc 22 to rotate in the annular groove inside the horizontal plate 21. During the relative movement of the two pull plates 23, the pull plates 23 can push the buckle plate 24 to move, so that the distance between the two buckle plates 24 on the left and right can be adapted to the opening size of the top of the medicine tank 1 of different diameters, improving the adaptability. When the inner side of the buckle plate 24 is attached to the outer side of the top of the medicine tank 1, the fixing screw 25 can be rotated in the threaded hole of the horizontal plate 21, which can drive the shaft end of the fixing screw 25 to abut against the inner wall of the groove of the pull plate 23 for locking and fixing. Secondly, according to Figure 6 and Figure 7 As shown, the drive motor 31 is started by connecting an external power source. The shaft end of the drive motor 31 can drive the rotating shaft 32 to rotate. The rotating shaft 32 can control the rotation of the blade shaft 333 through the bushing 331 and the U-shaped clip 332. When the blade shaft 333 rotates, it can drive the liquid medicine to form a centrifugal concave vortex. At this time, the rotating shaft 32 can drive the bottom leaf-turning plate 34 to rotate. Under the elastic push of the rubber block 35, the rubber plate 36 can stick to the inner wall of the medicine tank 1. During the rotation of the rotating shaft 32 and the leaf-turning plate 34, the rubber block 35 and the rubber plate 36 are driven to flip the bottom of the medicine tank 1, improve the mixing effect. At the same time, the rubber plate 36 can hang the wall-mounted medicine down to reduce the residual leakage rate.
