Description

Technical Field

[0001] This utility model relates to the field of aluminum sulfate pulverization technology, specifically a pulverizing device for aluminum sulfate production. Background Technology

[0002] Aluminum sulfate is an inorganic compound, a white crystalline powder. In the paper industry, it is used as a precipitant for rosin, wax emulsions, and other adhesives; in water treatment, as a flocculant; as an internal residue in foam fire extinguishers; as a raw material for manufacturing alum and aluminum dioxide; as a decolorizing and deodorizing agent for petroleum; as a raw material for pharmaceuticals; and in the manufacture of artificial gemstones and high-grade ammonium alum. In the production process of aluminum sulfate, to reduce the particle size, a pulverizing device is needed to crush the aluminum sulfate for easier subsequent weighing and packaging. In existing technology, aluminum sulfate is poured into a pulverizing device, where it is pulverized by the movement of the pulverizing blades. To reduce the number of feeding operations, a feeding hopper is often installed at the top of the pulverizing device, where the aluminum sulfate is stored and automatically fed by its own weight. However, controlling the feeding amount is inconvenient, and overfeeding can easily occur, leading to blockages and affecting the pulverizing efficiency. Utility Model Content

This device automatically controls the feeding speed of aluminum sulfate, avoids excessive feeding of aluminum sulfate which may cause blockage, and improves the crushing efficiency of the crushing device. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for aluminum sulfate production, comprising a crushing shell and a feeding mechanism;

[0005] Crushing shell: A feeding hopper is provided at the feed inlet at the upper end of the crushing shell. A fixed conical tube is provided on the inner arc surface of the crushing shell. A discharge pipe is provided at the lower opening of the fixed conical tube. A rotating column is rotatably connected to the middle of the discharge pipe. A conical tube is provided on the outer arc surface of the rotating column. Crushing blades are provided on both the outer arc surface of the conical tube and the inner arc surface of the fixed conical tube. The distance between the outer arc surface of the conical tube and the inner arc surface of the fixed conical tube gradually decreases from top to bottom.

[0006] Feeding mechanism: Located at the upper end of the crushing shell, the lower end of the feeding mechanism is fixedly connected to the rotating column. It automatically controls the feeding speed of aluminum sulfate, so that the feeding speed of aluminum sulfate is proportional to the rotation speed of the crushing parts, avoiding excessive feeding of aluminum sulfate and causing blockage, and improving the crushing efficiency of the crushing device.

[0007] Furthermore, the feeding mechanism includes a feeding tray, which is slidably connected to the upper end of the conical tube. The conical arc surface of the feeding tray is fitted with the conical inner arc surface at the upper end of the inner arc surface of the crushing shell to control the feeding of aluminum sulfate.

[0008] Furthermore, the feeding mechanism also includes limiting slide columns and support plates. The limiting slide columns are respectively disposed on the lower surface of the feeding tray, and the support plates are respectively disposed on the inner arc surface of the crushing shell. The limiting slide columns and the guide holes in the middle of the support plates are vertically slidably connected to restrict the rotation of the feeding tray.

[0009] Furthermore, the feeding mechanism also includes a reciprocating screw and a sliding column. The reciprocating screw is located at the upper end of the rotating column, and the outer arc surface of the reciprocating screw is threadedly connected to the sliding column. The sliding column is vertically slidably connected to the sliding hole on the lower surface of the feeding plate. Limiting plates are provided at both the upper and lower ends of the sliding column to provide power for the movement of the feeding plate.

[0010] Furthermore, the feeding mechanism also includes a spring, which is disposed between the limiting plate at the lower end of the slide column and the feeding plate. The spring is movably sleeved on the outer side of the slide column to provide clearance for the movement of the slide column.

[0011] Furthermore, the outer arc surface of the crushing shell is provided with a control switch, the input end of which is electrically connected to an external power source to control the start and stop of the entire device.

[0012] Furthermore, a motor is provided on the bottom wall of the crushing shell, the output shaft of the motor is fixedly connected to the rotating column, and the input end of the motor is electrically connected to the output end of the control switch to provide power for the rotation of the rotating column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This pulverizing device for aluminum sulfate production has the following advantages:

[0014] In the production process of aluminum sulfate, the motor is started by a control switch, causing the conical tube to rotate and pour aluminum sulfate into the crushing shell. When the aluminum sulfate enters between the conical tube and the fixed conical tube, the relative rotation of the conical tube and the fixed conical tube causes the crushing blades to crush the aluminum sulfate. During the crushing process, the reciprocating screw rotates with the rotating column, driving the sliding column and the feeding plate to move up and down. When the feeding plate moves downward, the distance between the conical arc surface of the feeding plate and the inner wall of the crushing shell increases, allowing the aluminum sulfate to fall smoothly downward. When the feeding plate moves upward, the distance between the conical arc surface of the feeding plate and the inner wall of the crushing shell decreases, blocking the aluminum sulfate from falling. The feeding speed of aluminum sulfate is automatically controlled so that it is proportional to the rotation speed of the crushing components, avoiding excessive aluminum sulfate feeding and blockage, and improving the crushing efficiency of the crushing device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a pulverizing device for aluminum sulfate production, comprising a pulverizing shell 1 and a feeding mechanism 9;

[0021] Crushing Shell 1: A feed hopper 2 is provided at the feed inlet at its upper end to facilitate the entry of aluminum sulfate into the crushing shell 1. A fixed conical tube 3 is provided on the inner arc surface of the crushing shell 1. A discharge pipe 6 is provided at the lower opening of the fixed conical tube 3. A rotating column 4 is rotatably connected to the middle of the discharge pipe 6. A conical tube 5 is provided on the outer arc surface of the rotating column 4. Crushing blades are provided on both the outer arc surface of the conical tube 5 and the inner arc surface of the fixed conical tube 3. The distance between the outer arc surface of the conical tube 5 and the inner arc surface of the fixed conical tube 3 gradually decreases from top to bottom. The central axis of the rotating column 4 is collinear with the central axis of the fixed conical tube 3. The rotating column 4 drives the crushing shell 1. When the conical tube 5 rotates, and aluminum sulfate enters between the conical tube 5 and the fixed conical tube 3, the relative rotation of the conical tube 5 and the fixed conical tube 3 causes the crushing blades to crush the aluminum sulfate. The crushed aluminum sulfate will be discharged through the discharge pipe 6. The outer arc surface of the crushing shell 1 is equipped with a control switch 8. The input end of the control switch 8 is electrically connected to an external power source to control the start and stop of the entire device. The bottom wall of the crushing shell 1 is equipped with a motor 7. The output shaft of the motor 7 is fixedly connected to the rotating column 4. The input end of the motor 7 is electrically connected to the output end of the control switch 8 to provide power for the rotation of the rotating column 4.

[0022] Feeding mechanism 9: Located at the upper end of the crushing shell 1, the lower end of the feeding mechanism 9 is fixedly connected to the rotating column 4. The feeding mechanism 9 includes a feeding plate 91, which is slidably connected to the upper end of the inner wall of the tapered tube 5. The tapered arc surface of the feeding plate 91 is fitted with the tapered inner arc surface at the upper end of the inner arc surface of the crushing shell 1. By moving the feeding plate 91 up and down, the distance between the tapered arc surface of the feeding plate 91 and the inner wall of the crushing shell 1 is adjusted to control the feeding speed of aluminum sulfate. The feeding mechanism 9 also includes a limiting slide column 92 and a support plate 93. The limiting slide column 92 is respectively located on the lower surface of the feeding plate 91, and the support plate 93 is respectively located on the inner arc surface of the crushing shell 1. The limiting slide column 92 and the guide hole in the middle of the support plate 93 are vertically slidably connected to restrict the rotation of the feeding plate 91. The feeding mechanism 9 also includes a reciprocating screw 94 and a slide column 95. The reciprocating screw 94 is located at the upper end of the rotating column 4. The reciprocating screw 94 is threadedly connected to a sliding column 95 on its outer arc surface. The sliding column 95 is vertically slidably connected to a sliding hole on the lower surface of the feeding plate 91. Limiting plates are provided at both the upper and lower ends of the sliding column 95. During the crushing process, the reciprocating screw 94 rotates together with the rotating column 4. Through the threaded connection between the sliding column 95 and the reciprocating screw 94, the sliding column 95 is driven to move up and down reciprocally. The limiting plates at both ends of the sliding column 95 apply force to the feeding plate 91, providing power for the up and down movement of the feeding plate 91. The feeding mechanism 9 also includes a spring 96. The spring 96 is set between the limiting plate at the lower end of the sliding column 95 and the feeding plate 91. The spring 96 is movably sleeved on the outer side of the sliding column 95. Through the extension and retraction of the spring 96, space is provided for the up and down movement of the sliding column 95, avoiding the presence of aluminum sulfate between the conical arc surface of the feeding plate 91 and the inner wall of the crushing shell 1, which would affect the normal movement of the sliding column 95.

[0023] The working principle of the pulverizing device for aluminum sulfate production provided by this utility model is as follows: During the production process of aluminum sulfate, the motor 7 is started by the control switch 8. The output shaft of the motor 7 drives the rotating column 4 and the conical tube 5 to rotate. At the same time, aluminum sulfate is poured into the pulverizing shell 1 through the feed hopper 2. The aluminum sulfate falls into the pulverizing shell 1 and enters between the outer arc surface of the conical tube 5 and the inner arc surface of the fixed conical tube 3. The relative rotation of the conical tube 5 and the fixed conical tube 3 causes the pulverizing blades to pulverize the aluminum sulfate. The pulverized aluminum sulfate is discharged through the discharge pipe 6. During the pulverizing process, the reciprocating screw 94 rotates together with the rotating column 4. The vertical sliding of the limiting slide 92 and the support plate 93 restricts the rotation of the feeding plate 91 and the slide 95. 5 is threadedly connected to the reciprocating screw 94, driving the slide column 95 to move up and down reciprocally. When the slide column 95 moves downward, the limiting plate at the upper end of the slide column 95 applies a force to the feeding plate 91, pulling the feeding plate 91 downward. The distance between the conical arc surface of the feeding plate 91 and the inner wall of the crushing shell 1 increases, allowing aluminum sulfate to fall down through the gap between the feeding plate 91 and the inner wall of the crushing shell 1. When the slide column 95 moves upward, the limiting plate at the lower end of the slide column 95 overcomes the elastic force of the spring 96, pushing the feeding plate 91 upward, reducing the distance between the conical arc surface of the feeding plate 91 and the inner wall of the crushing shell 1, blocking the falling of aluminum sulfate, and making the feeding speed of aluminum sulfate proportional to the rotation speed of the crushing component, avoiding excessive aluminum sulfate feeding that would affect the crushing effect.

[0024] It is worth noting that the motor 7 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended to use the 5I K40RGU-CF model motor. The control switch 8 is equipped with a switch button corresponding to the motor 7 for controlling its switching operation.

[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
