Description

Technical Field

[0001] This utility model relates to the field of mineral powder production technology, and in particular to a hoist for mineral powder production. Background Technology

[0002] Mineral powder is a general term for stone powder and its substitutes that meet engineering requirements. It is the product of ore crushing and processing, and is the first and one of the most important steps in ore processing and smelting. The hydrophilicity coefficient of mineral powder is the ratio of the volume of expansion of a unit volume of mineral powder in water (polar molecules) to the volume of expansion of an equal volume of kerosene (non-polar molecules). In highway engineering, mineral powder with a hydrophilicity coefficient <1 is called alkaline mineral powder.

[0003] Currently, in mineral powder production, the raw materials still contain particulate matter after passing through the vertical mill. At this point, an elevator is needed to lift the screened particles back to the vertical mill for processing. The screened particles still have a large amount of mineral powder attached to their surface. Existing elevators do not have a screening function and cannot separate the mineral powder from the surface of the particles. Furthermore, they cannot adjust the discharge height of the elevator according to the height of the mill, so their practicality needs to be improved. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, one of the objectives of this utility model is to provide a hoist for mineral powder production. Through a rotating frame, connecting lug one, an electric hydraulic cylinder, and connecting lug two, the tilt angle of the hoist can be adjusted, thereby adjusting the discharge height. It is suitable for use with mills of different specifications and is highly practical. Through a sieving assembly, connecting lug three, an electric push rod, connecting lug four, and a vibration assembly, the tilt angle of the sieving assembly can be adjusted to keep it parallel to the horizontal plane. During discharge, the vibration assembly strikes the sieving plate, performing vibration treatment to separate the mineral powder and granules, facilitating subsequent processing and greatly improving processing efficiency.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a hoist for producing mineral powder, comprising: a base plate 1, four self-locking casters 2 mounted on the base plate 1, a rotating frame 3 and a connecting ear 7 fixedly connected to the upper surface of the base plate 1, the connecting ear 7 being located in front of the rotating frame 3, a hoist body 4 rotatably connected to the inner wall of the rotating frame 3, an electric hydraulic cylinder 8 rotatably connected to the inner wall of the connecting ear 7, a connecting ear 9 rotatably connected to the top of the movable rod of the electric hydraulic cylinder 8, the rear wall of the connecting ear 9 being fixedly connected to the front wall of the hoist body 4, connecting plates 5 fixedly connected to the left and right side walls of the hoist body 4, a screening assembly 6 rotatably disposed between the two connecting plates 5, a connecting ear 3 10 fixedly connected to the front wall of the hoist body 4, an electric push rod 11 rotatably connected to the inner wall of the connecting ear 3 10, a connecting ear 4 12 rotatably connected to the top of the movable rod of the electric push rod 11, and the front wall of the connecting ear 4 12 being fixedly connected to the rear wall of the screening assembly 6;

[0024] The screening assembly 6 includes a frame 601. The left and right outer walls of the frame 601 are rotatably connected to the opposite surfaces of two connecting plates 5. The frame 601 is located below the discharge hole of the elevator body 4. A bearing plate 605 is fixedly connected to the inner wall of the frame 601. Four springs 606 are fixedly connected to the bearing plate 605. An inclined screening plate 604 is fixedly connected to the top of the springs 606. A vibration assembly 13 is provided below the screening plate 604. A discharge port 603 is opened on the front wall of the frame 601. The screening plate 604 is located inside the discharge port 603. A guide plate 602 is fixedly connected to the bottom of the frame 601. The guide plate 602 is inclined and its lower end is located on the left side.

[0025] The vibration assembly 13 includes a motor 1301, an electric hydraulic cylinder 8, an electric push rod 11, and a controller electrically connected to the motor 1301. The outer wall of the motor 1301 is fixedly connected to the outer wall of the frame 601. The output end of the motor 1301 passes through the side wall of the frame 601 and is fixedly connected to a rotating shaft 1302. An eccentric wheel 1303 is fixedly connected to the outer wall of the rotating shaft 1302. The top end of the eccentric wheel 1303 abuts against the bottom end of the sieve plate 604. By using the rotating frame 3, connecting ear 1 7, electric hydraulic cylinder 8, and connecting ear 2 9, when adjusting the discharge height of the elevator, the electric hydraulic cylinder 8 is activated to extend its movable rod. With the rotating frame 3 as the fulcrum, the electric hydraulic cylinder 8 moves between connecting ear 1 7 and connecting ear 2 9, thereby adjusting the tilt angle of the elevator and thus the discharge height. This method is suitable for use with mills of different specifications and is highly practical. Alternatively, by using the screening assembly 6, connecting ear 3 10, electric push rod 11, connecting ear 4 12, and vibration assembly 13, after adjusting the discharge height of the elevator, the electric push rod 11 extends its movable rod... With the connecting plate 5 as the pivot point, the electric push rod 11 moves between the connecting ear 3 10 and the connecting ear 4 12 to adjust the tilt angle of the frame 601 so that it remains parallel to the horizontal plane. When discharging, the material falls into the frame 601, and the motor 1301 drives the rotating shaft 1302 to rotate, which drives the eccentric wheel 1303 to rotate and cooperate with the spring 606 to knock on the screen plate 604 for vibration treatment. The screened mineral powder is discharged and collected through the guide plate 602, and the particulate matter is discharged through the inclined screen plate 604 to the discharge port 603 and falls into the mill for processing, which greatly improves the processing efficiency.

[0026] Working principle: During use, adjust the discharge height of the elevator according to the specifications of the mill. Start the telescopic rod of the electric hydraulic cylinder 8. With the rotating frame 3 as the fulcrum, the electric hydraulic cylinder 8 moves between the connecting ear 1 7 and the connecting ear 2 9, which can drive the adjustment of the tilt angle of the elevator, thereby adjusting the discharge height. After adjusting the discharge height of the elevator, the telescopic rod of the electric push rod 11 moves between the connecting ear 3 10 and the connecting ear 4 12, with the connecting plate 5 as the fulcrum, adjusting the tilt angle of the frame 601 to keep it parallel to the horizontal plane. When the elevator discharges, the material falls into the frame 601. The motor 1301 drives the rotating shaft 1302 to rotate, which drives the eccentric wheel 1303 to rotate. In conjunction with the spring 606, the screen plate 604 is struck and vibrated. The screened mineral powder is discharged and collected through the guide plate 602, and the particulate matter is discharged through the discharge port 603 through the inclined screen plate 604 and falls into the mill for processing.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
