[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A drum drying device for processing foundry bentonite includes a base plate, with casters fixedly installed at the four corners of the bottom of the base plate. A push rod is fixedly connected to one side of the top of the base plate. Two sets of support plates are fixedly connected to the upper surface of the base plate near the push rod.

[0015] Preferably, the fixing component includes a threaded rod, which is threadedly connected to the top of the filter box. The bottom of the threaded rod is rotatably connected to a positioning plate via a bearing. A limit rod is fixedly connected to one side of the top of the positioning plate, and the limit rod is slidably embedded inside the filter box.

[0016] The technical effect of adopting the above-mentioned further solution is as follows: First, rotate the threaded rod, and the threaded rod moves away from the filter plate.

By setting up a filtration mechanism, with the cooperation of a filter box, slot, hot air blower, filter plate, fixing parts and positioning groove, it can filter out external impurities, preventing impurities from affecting the purity of bentonite. At the same time, it can quickly disassemble and assemble the filter plate, which is convenient for cleaning and replacement. By setting up a lifting component, with the cooperation of hydraulic cylinder, U-shaped plate, roller and slide rail, the height of the discharge port at the end of the conveying auger can be adjusted, which is convenient for collecting the dried bentonite.

[0028] Example 1

[0029] The technical solution in this application embodiment effectively solves the problem that the discharge port at the end of the auger in the above-mentioned solution is at a certain height and cannot be adjusted, which causes inconvenience when collecting the processed bentonite. In addition, the above solution uses a hot air blower to dry the bentonite inside the auger, which introduces impurities from the outside air into the bentonite, affecting the purity of the bentonite. The overall idea is as follows:

[0030] like Figures 1 to 5 To address the problems existing in the prior art, this utility model provides a drum drying device for processing cast bentonite, including a base plate 1. Universal wheels 12 are fixedly installed at the four corners of the bottom of the base plate 1. A push rod 11 is fixedly connected to one side of the top of the base plate 1. Two sets of support plates 13 are fixedly connected to the upper surface of the base plate 1 near the push rod 11. A conveying auger 3 is rotatably connected between the support plates 13. A filter mechanism 4 is provided at the top of the conveying auger 3. A lifting assembly 5 is provided between the conveying auger 3 and the base plate 1. The lifting assembly 5 includes a hydraulic cylinder 51, which is fixedly installed on the upper surface of the base plate 1. A U-shaped plate 52 is fixedly connected above the movable end of the hydraulic cylinder 51. A roller 53 is rotatably connected to the middle of the U-shaped plate 52. A slide rail 54 corresponding to the roller 53 is fixedly connected to the bottom of the conveying auger 3.

[0031] By adopting the above technical solution, when adjusting the height of the discharge port at the end of the conveying auger 3, the hydraulic cylinder 51 is activated, and the hydraulic cylinder 51 drives its movable end to extend and retract. During the extension and retraction process, the height of the discharge port at the end of the conveying auger 3 can be adjusted, which facilitates the collection of bentonite. The roller 53 rolls on the slide rail 54 at the bottom of the conveying auger 3, which can reduce the friction between the conveying auger 3 and the hydraulic cylinder 51.

[0032] Specifically, a connecting plate 21 is fixedly connected to the middle of both sides of the base plate 1, and an electric actuator 22 is fixedly connected above the connecting plate 21. A friction plate 23 is fixedly connected to the output end of the electric actuator 22.

[0033] By adopting the above technical solution, the electric push rods 22 on both sides of the base plate 1 can be opened. The movable end of the electric push rod 22 drives the friction plate 23 to move downward until the friction plate 23 is in close contact with the ground, which can enhance the stability of the device and prevent slippage during use.

[0034] Example 2

[0035] like Figures 1 to 5 The filtration mechanism 4 includes a filter box 41, which is fixedly connected to the upper end of the conveying auger 3. A hot air blower 43 is fixedly installed inside the filter box 41. A slot 42 is provided on one side of the filter box 41, and a filter plate 44 is inserted into the slot 42. A fixing member 45 is provided on the top of the filter box 41 near the slot 42. A positioning groove 46 corresponding to the fixing member 45 is provided on the surface of the filter plate 44. The fixing member 45 includes a threaded rod 451, which is threadedly connected to the top of the filter box 41. A positioning plate 452 is rotatably connected to the bottom of the threaded rod 451 through a bearing. A limit rod 453 is fixedly connected to one side of the top of the positioning plate 452 and is slidably embedded inside the filter box 41.

[0036] By adopting the above technical solution, the hot air blower 43 can heat the outside air and deliver it into the conveying auger 3. At the same time, the filter plate 44 can filter out impurities from the outside air to prevent impurities from affecting the purity of the bentonite. When replacing the filter plate 44, first rotate the threaded rod 451. The threaded rod 451 moves away from the filter plate 44. At this time, the positioning plate 452 moves vertically upward under the restriction of the limiting rod 453 until the positioning plate 452 is completely removed from the positioning groove 46. Only then can the filter plate 44 be taken out of the slot 42 for cleaning or replacement. Similarly, the filter plate 44 can be installed.

[0037] Working Principle: During operation, when adjusting the height of the discharge port at the end of the conveying auger 3, the hydraulic cylinder 51 is activated. The hydraulic cylinder 51 drives its movable end to extend and retract, adjusting the height of the discharge port at the end of the conveying auger 3 to facilitate the collection of bentonite. The roller 53 rolls on the slide rail 54 at the bottom of the conveying auger 3, reducing friction between the conveying auger 3 and the hydraulic cylinder 51. The hot air blower 43 heats the outside air and delivers it into the conveying auger 3. Simultaneously, the filter plate 44 filters out impurities from the outside environment, preventing them from affecting the purity of the bentonite. When replacing the filter plate 44, first rotate the threaded rod 451. The threaded rod 451 moves away from the filter plate 44. At this time, the positioning plate 452 moves vertically upward under the restriction of the limiting rod 453 until the positioning plate 452 is completely disengaged from the positioning groove 46. Only then can the filter plate 44 be removed from the slot 42 for cleaning or replacement. Similarly, the filter plate 44 can be installed. The electric push rods 22 on both sides of the base plate 1 can be opened. The movable end of the electric push rod 22 drives the friction plate 23 to move downward until the friction plate 23 is in close contact with the ground. This can enhance the stability of the device and prevent slippage during use.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
