Description

Technical Field

[0001] The utility model relates to the technical field of bentonite production, in particular to a heating and dehumidifying device for bentonite production. Background Art

[0002] Bentonite is a non-metallic mineral mainly composed of montmorillonite. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons. Since there are certain cations in the layered structure formed by the montmorillonite unit cell, such as Cu, Mg, Na, K, etc., and the interaction between these cations and the montmorillonite unit cell is very unstable and easy to be exchanged by other cations, it has good ion exchangeability.

[0003] For example, the disclosed CN213090333U discloses a bentonite dehumidifying and drying device, including a frame, a drying cylinder that is inclined and rotatably arranged on the frame, a driving mechanism arranged on the frame to drive the drying cylinder, a heating mechanism arranged outside the drying cylinder, and a blowing mechanism arranged corresponding to the discharge port of the drying cylinder; the heating mechanism includes annular grooves arranged on the side surfaces at both ends of the drying cylinder, an annular plate rotatably arranged in the annular grooves, a cylindrical plate arranged between the outer edges of the two annular plates, a heat insulation layer arranged outside the cylindrical plate, a column for supporting the cylindrical plate arranged on the ground, an air inlet arranged at the lower end of the cylindrical plate, an air outlet arranged at the upper end of the cylindrical plate, the air inlet is communicated with the heat supply mechanism, and the air outlet is communicated with the waste discharge pipe.

[0004] However, in the prior art, when drying bentonite, generally, the heating method is used for dehumidification to evaporate the internal moisture. But the actual situation is that when heating and dehumidifying, the bentonite is piled up together. Due to the influence of heat conduction and heat convection, the bentonite piled up outside is more likely to be affected by heat, and the evaporation rate of its internal moisture is also faster. While the bentonite located inside the pile, due to the shielding of the outer bentonite, receives relatively less heat, resulting in a slower moisture evaporation rate. This causes the phenomenon that the heating of bentonite is not uniform during the drying process, and also leads to unstable quality, and some will deteriorate or the structure will be damaged due to overheating. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the prior art, when heating and dehumidifying, the bentonite is piled up together, resulting in uneven heating of the bentonite during the drying process, and a heating and dehumidifying device for bentonite production is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a heating and dehumidifying device for bentonite production, including a conveyor and a heating box installed on the top thereof, a plurality of storage boxes are arranged on the top of the conveyor, a breathable net is installed on the side wall of the storage box, and a soil turning mechanism is installed inside the heating box;

[0007] The soil-turning mechanism includes two mounting frames and a second transmission rod. Two connecting rods are fixedly connected to the top of the mounting frame. A rotating rod is rotatably connected to the top end of the mounting frame. A first crank is fixedly connected to the outer surface of one end of the rotating rod, and a second crank is fixedly connected to the outer surface of the other end of the rotating rod. The bottom end of the first crank is rotatably connected to a first transmission rod. One end of the second transmission rod is rotatably connected to the two second cranks respectively. The other end of the second transmission rod is rotatably connected to a soil-turning plate. The middle parts of both sides of the soil-turning plate are rotatably connected to one end of the first transmission rod.

[0008] Preferably, a driving motor is fixedly connected to the inner side of the mounting frame, and a driving bevel gear is fixedly connected to the output end of the driving motor.

[0009] Preferably, a driven bevel gear is meshed and connected to one side of the driving bevel gear, and the inner side of the driven bevel gear is fixedly connected to the outer wall of the rotating rod.

[0010] Preferably, two limiting rods are fixedly connected to the bottom of the mounting frame, and a roller is rotatably connected to the middle of the soil-turning plate.

[0011] Preferably, the roller is slidably connected to the limiting rod.

[0012] Preferably, a lifting plate is fixedly connected to the top of the connecting rod, and a cylinder is fixedly installed on the top of the heating box.

[0013] Preferably, the top of the cylinder is fixedly connected to the bottom of the lifting plate, and a through hole is opened on the top of the heating box.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0015] 1. In the present utility model, through the synchronous rotation of the two rotating rods, the first crank and the second crank start to perform circular motion. Subsequently, the first transmission rod drives the soil-turning plate to move up and down, while the second transmission rod is responsible for controlling the soil-turning plate to perform flipping motion. This motion mode of the soil-turning plate can not only ensure that the bentonite inside the storage box is evenly turned over, so that every part can be fully exposed to the heat source, but also make part of the bentonite surface slide down through the inclination and flipping of the soil-turning plate, thereby further increasing its contact area with the heat source and improving the heating effect.

[0016] 2. In the present utility model, through the precise control of the cylinder, the soil-turning plate can effectively turn over the bentonite while avoiding excessive disturbance inside the storage box, thus ensuring the stability and efficiency of the drying process. The operation of the driving motor drives the driving bevel gear to rotate, and then transmits the power to the driven bevel gear through the meshing relationship, so that the rotating rod and the soil-turning plate can move up and down and flip. The roller keeps rolling during the movement of the soil-turning plate, enhancing the stability of the soil-turning plate. Description of the Drawings

Detailed implementation manners

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, the present utility model provides a heating and dehumidifying device for bentonite production, including a conveyor 1 and a heating box 2 installed on top thereof. A plurality of storage boxes 4 are arranged on the top of the conveyor 1. A breathable net 41 is installed on the side wall of the storage box 4. A soil-turning mechanism 3 is installed inside the heating box 2;

[0026] The soil-turning mechanism 3 includes two mounting brackets 33 and a second transmission rod 39. Two connecting rods 331 are fixedly connected to the top of the mounting bracket 33. A rotating rod 34 is rotatably connected to the top end of the mounting bracket 33. One end of the outer surface of the rotating rod 34 is fixedly connected with a first crank 35, and the other end of the outer surface of the rotating rod 34 is fixedly connected with a second crank 38. The bottom end of the first crank 35 is rotatably connected with a first transmission rod 36. One end of the second transmission rod 39 is rotatably connected with the two second cranks 38 respectively. The other end of the second transmission rod 39 is rotatably connected with a soil-turning plate 37. The middle parts on both sides of the soil-turning plate 37 are rotatably connected with one end of the first transmission rod 36.

[0027] Specifically, the specific settings and functions of this embodiment will be described below. When the two rotating rods 34 rotate synchronously and in the same direction, they not only drive the first crank 35 to perform circular motion around it. The rotational motion of the first crank 35 is transmitted to the first transmission rod 36, causing the first transmission rod 36 to produce corresponding movements. Since the soil-turning plate 37 is rotatably connected to the bottom end of the first crank 35, the movement of the first transmission rod 36 will directly act on the soil-turning plate 37, causing it to start moving. This movement includes not only up and down lifting, but also movement in a specific direction due to the force of the first transmission rod 36.

[0028] During this process, the second cranks 38 at the opposite ends of the two rotating rods 34 are also performing synchronous circular motions. These two second cranks 38 will simultaneously exert forces on the second transmission rod 39. The main function of the second transmission rod 39 is to control the rotation of the soil-turning plate 37, that is, to make it swing while performing the lifting action. This swinging action helps to turn the bentonite more comprehensively, ensuring that every part of the bentonite can be fully heated and dehumidified.

[0029] This movement mode of the soil-turning plate 37 can not only ensure that the bentonite in the storage box 4 is evenly turned, so that every part can be fully exposed to the heat source, but also make some parts on the surface of the bentonite slide off through the inclination and flipping of the soil-turning plate 37, further increasing its contact area with the heat source and improving the heating efficiency. In addition, this turning helps to break the hard lumps or agglomerates that may exist in the bentonite accumulation, thus ensuring the smooth progress of the entire heating and dehumidifying process.

[0030] Embodiment Two

[0031] As Figures 2-4As shown in the figure, a driving motor 343 is fixedly connected to the inner side of the mounting frame 33. The output end of the driving motor 343 is fixedly connected to a driving bevel gear 342. A driven bevel gear 341 is meshed and connected to one side of the driving bevel gear 342. The inner side of the driven bevel gear 341 is fixedly connected to the outer wall of the rotating rod 34. Two limiting rods 332 are fixedly connected to the bottom of the mounting frame 33. A roller 371 is rotatably connected to the middle of the soil turning plate 37. The roller 371 is slidably connected to the limiting rods 332. The top of the connecting rod 331 is fixedly connected to a lifting plate 31. A cylinder 32 is fixedly installed on the top of the heating box 2. The top of the cylinder 32 is fixedly connected to the bottom of the lifting plate 31. A through hole is opened on the top of the heating box 2.

[0032] The effect achieved by the entire embodiment is that during the drying process of bentonite, the cylinder 32 can accurately control the depth of the soil turning plate 37 entering or exiting the storage box 4. This precise control ensures that the soil turning plate 37 can effectively turn the bentonite, while avoiding excessive disturbance inside the storage box 4, and guaranteeing the stability and efficiency of the drying process.

[0033] When the driving motor 343 operates, it drives the driving bevel gear 342 to start rotating. The meshing relationship between the driving bevel gear 342 and the driven bevel gear 341 ensures the effective transmission of power. As the driven bevel gear 341 rotates, the rotating rod 34 also starts to rotate, thereby driving the soil turning plate 37 to move up and down and flip.

[0034] During the up and down movement of the soil turning plate 37, the roller 371 plays a key role. It is restricted by the limiting rods 332 and remains in a rolling state when the soil turning plate 37 moves, ensuring the stability of the soil turning plate 37 during the movement.

[0035] At the same time, the ventilation net 41 installed on the side wall of the storage box 4 provides the necessary ventilation conditions for the drying of bentonite. Its aperture can not only allow air to freely enter the inside of the storage box 4, enabling the bentonite to fully contact the hot air and dry quickly, but also effectively prevent the bentonite particles from leaking out through the ventilation net 41.

[0036] During the entire drying process, the conveyor 1 is responsible for sending the storage box 4 into the heating box 2 for drying and sending the storage box 4 out after drying. This automated conveying method greatly improves the work efficiency and reduces the complexity and error of manual operation.

[0037] The usage method and working principle of this device: The cylinder 32 is used to control the up and down movement of the pushing lifting plate 31, enabling the soil turning plate 37 to extend into or leave the inside of the storage box 4, thereby realizing the drying of the bentonite inside the storage box 4. After drying is completed, the conveyor 1 will control the storage box 4 to leave the inside of the heating box 2.

[0038] During the drying process, the startup of the driving motor 343 drives the rotation of the driving bevel gear 342. The driving bevel gear 342 applies a force to the driven bevel gear 341 through meshing, thereby causing the two rotating rods 34 to start rotating synchronously. When the rotating rod 34 rotates, the first crank 35 connected thereto will perform a circular motion centered on the rotating rod 34. This motion further drives the movement of the first transmission rod 36. Since the bottom end of the first crank 35 is rotatably connected to the soil-turning plate 37 and the first transmission rod 36 applies a force to the soil-turning plate 37, the soil-turning plate 37 will start to move under the guidance of the first transmission rod 36.

[0039] Meanwhile, the second cranks 38 at the opposite ends of the two rotating rods 34 will also rotate accordingly and perform circular motions together with the first crank 35. These two second cranks 38 will simultaneously apply forces to the second transmission rod 39, causing the second transmission rod 39 to control the rotation of the soil-turning plate 37. In this way, while the soil-turning plate 37 moves up and down following the first transmission rod 36, it will also swing under the action of the second transmission rod 39.

[0040] The up-and-down movement and continuous flipping action of the soil-turning plate 37 cause the bentonite inside the storage box 4 to be continuously turned over during the heating and dehumidification process. The bentonite on the surface of the soil-turning plate 37 will also slide down as the soil-turning plate 37 tilts and flips, ensuring uniform heating of the bentonite.

[0041] During the up-and-down movement of the soil-turning plate 37, the roller 371 rolls under the restraint of the limiting rod 332. The cooperative action of this roller 371 and the limiting rod 332 ensures that the soil-turning plate 37 maintains a straight movement trajectory during the up-and-down movement, and thus stably performs the soil-turning operation on the bentonite.

[0042] In addition, the air-permeable net 41 installed on the side wall of the storage box 4 has a small pore diameter, which allows air to freely enter the inside of the storage box 4, thereby accelerating the drying speed of the bentonite. At the same time, the pore diameter design of the air-permeable net 41 can also effectively prevent the bentonite particles from spilling out of the inside of the storage box 4.

[0043] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
