Description

Technical Field

[0001] This utility model relates to the field of gypsum mixing equipment, specifically a powder feeding cylinder. Background Technology

[0002] In the process of making gypsum slurry, gypsum powder and water need to be mixed in the correct proportions and then placed into a mixer for stirring. Vacuuming and negative pressure adjustment are crucial steps in this process. During production, the powder needs to be manually moved from the machine in the upper stage to the feeding port of the gypsum vacuum mixing drum. This process is extremely inefficient and increases labor costs. Repeatedly opening and closing the feeding port of the gypsum vacuum mixer during feeding can easily lead to a loose seal, affecting the mixing effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a powder feeding cylinder that can transport powder materials.

[0004] To solve the above-mentioned technical problems, this utility model includes a cylinder, characterized by the following: the upper end of the cylinder has an upper opening, the lower end of the cylinder has a powder outlet, the upper opening of the cylinder has a cover plate that can be opened and closed and can seal the upper opening, a rotatable powder storage bucket is installed inside the cylinder, the powder storage bucket has an inner cavity for storing powder, the powder storage bucket has an opening that penetrates the inner cavity, the opening can face the upper opening of the cylinder and the powder outlet respectively after the powder storage bucket rotates, and a buckle is provided on the lower end face of the cylinder.

[0005] With the above structure, the powder is held in a rotating storage hopper inside the cylinder. When the storage hopper rotates to the point where the opening faces upward, the powder is poured in from the top opening of the cylinder. The powder enters the inner cavity of the storage hopper through the opening. Then, the cover plate is installed at the top opening to seal the top opening of the cylinder. The cylinder is then transported to the inlet of the gypsum vacuum mixer. The cylinder is installed on the gypsum vacuum mixer by aligning the clips and fixing the position of the cylinder with the clips. Then, the storage hopper is rotated so that the opening of the storage hopper faces the bottom of the cylinder. Due to the negative pressure and gravity during vacuum mixing, all the powder falls from the storage hopper, completing the movement and feeding of the powder. During the movement, the storage hopper and cylinder design can achieve quantitative powder transport each time, and the powder is transported through the powder loading hopper. There is no need for manual handling of the powder, saving manpower and improving transportation efficiency.

[0006] The powder storage hopper is a spherical hopper with rotating shafts on both sides. These shafts are rotatably connected to the cylinder body, and the axes of the two shafts are on the same horizontal line. An adjustment device that can drive the shaft to rotate is fixed to the end of one of the rotating shafts. The spherical shape facilitates the rotation of the powder storage hopper without causing interference within the cylinder body. The rotation of the powder storage hopper along the two rotating shafts is driven by the rotation of the handle, which in turn drives the rotation of the shafts, causing the storage hopper to rotate along the same horizontal line. When the powder storage hopper rotates, the opening on the hopper also rotates along the horizontal axis, allowing the opening to face upwards or downwards, and thus towards the upper end of the cylinder body or the powder outlet. The direction of the opening of the powder storage hopper can be changed by the adjustment device, enabling the loading and unloading of powder in the hopper. This method is simple, convenient, and easy to operate.

[0007] The adjustment device is a handle fixed to one end of the rotating shaft. By rotating the handle, the rotating shaft and the storage tank can be rotated. The structure is simple, the operation is convenient, and the installation space is saved.

[0008] The cylinder is equipped with a limiting block to restrict the rotation position of the handle. The limiting block can restrict the rotation position of the inner powder storage tank, thereby fixing the orientation of the opening when the powder storage tank rotates. This ensures that the opening of the powder storage tank can be aligned with the upper opening of the cylinder and the powder outlet, guaranteeing the stability of feeding and unloading and ensuring quality.

[0009] The limiting block is equipped with a handle elastic clamp that can hold and fix the handle. After the handle cup limiting block restricts the position, the handle is fixed by the handle elastic clamp, which fixes the position of the handle and thus fixes the powder storage bucket, ensuring the stability of the opening and guaranteeing the stability of the powder during the transportation of the cylinder.

[0010] The device has three buckles, which are evenly distributed around the lower end face of the cylinder to better fix the position of the cylinder and ensure installation efficiency.

[0011] The cylinder is equipped with hooks on its side wall and handle seats are symmetrically installed on the cylinder. The two ends of the hooks are installed in the handle seats and are rotatably connected to the handle seats. After the hooks rotate along the handle seats, they rotate to the top of the cylinder. By using the lifting device to move the powder cylinder from the previous process to the next process, it is convenient to move and improves efficiency.

[0012] The side wall of the powder storage hopper corresponding to the opening is flat. Compared with the other end of the spherical hopper, the smaller inner cavity of the flat powder storage hopper results in the volume of the two sides of the powder storage hopper along the axis of rotation being similar. This avoids the powder storage hopper becoming unbalanced when holding powder when one end is too large, which could damage the axis of rotation and ensure the service life of the powder loading cylinder.

[0013] In summary, this utility model has the advantages of simple structure, improved efficiency, reduced labor costs, and guaranteed service life. Attached Figure Description

[0022] like Figure 1-7As shown, this utility model includes a cylindrical body 1 with an upper opening facing upwards and a powder outlet facing downwards at the lower end. A cover plate 2 is installed on the upper opening of the cylindrical body. A rotatable lifting hook is provided on the outside of the cylindrical body 1, and a rotatable powder storage tank 3 is provided in the cylindrical body 1. The powder storage tank 3 has an inner cavity 31 for holding powder, and an opening that penetrates the inner cavity 31 and the outer wall of the powder storage tank 3. After the powder storage tank 3 is rotated, the opening can face either the upper end or the lower end of the cylindrical body 1. A powder outlet is provided at the lower end of the cylindrical body 1, and a buckle 4 is provided at the powder outlet of the lower end of the cylindrical body 1, which is used to attach it to a gypsum vacuum mixer. When it is necessary to fill the powder storage tank 3 with powder, the upper sealing cover is opened, then the opening of the powder storage tank 3 is rotated to face the upper end of the cylindrical body 1, powder is filled into the inner cavity 31 of the powder storage tank 3, and then the cover plate 2 is sealed tightly. A hook 5 is installed on the side wall of the cylinder 1, and handle seats 13 are symmetrically installed on the cylinder 1. The two ends of the hook 5 are installed inside the handle seats 13. The cylinder 1 is lifted by the hook and then installed on the gypsum vacuum mixing tank by the buckle 4. Then the powder storage tank 3 is rotated so that the opening of the powder storage tank 3 faces downward. Then the powder falls into the gypsum vacuum mixer through the powder outlet of the cylinder 1. The sealing cover and the buckle 4 ensure the sealing of the cylinder 1. The vacuum adsorption ensures that all the powder falls out from the powder outlet, ensuring the efficiency of material transportation.

[0023] like Figure 1-7 As shown, there is an annular groove on the lower end face of the cover plate 2, and a sealing ring is installed in the annular groove. The upper side wall of the cylinder 1 can be installed in the annular groove, and the sealing between the cover plate 2 and the cylinder 1 is achieved through the sealing ring of the annular groove.

[0024] like Figure 6 As shown, the powder storage bin 3 has two rotating shafts 32 at both ends of its opening. The two rotating shafts 32 are at the same horizontal height and their axes are on the same horizontal line. The powder storage bin 3 rotates along the axes at both ends. Since the two rotating shafts 32 are located on both sides of the powder storage bin 3, the powder storage bin 3 rotates along the axes of the two rotating shafts 32. The cylinder 1 is provided with a support rotating shaft 32 sleeve for the rotating shaft 32 to rotate. One end of the rotating shaft 32 is installed in the support rotating shaft 32 sleeve. The other end of the rotating shaft 32 extends out through the cylinder 1. The cylinder 1 is provided with a rotating rotating shaft 32 sleeve for the rotating shaft 32 to extend out at one end. The outer end of the rotating shaft 32 is provided with a handle seat and a handle. By rotating the handle, the powder storage bin 3 can be rotated, thereby changing the orientation of the opening of the powder storage bin 3 inside the bin. When it is necessary to feed material inward, the opening of the powder storage bin 3 is turned upward by rotating the handle. When it is necessary to unload material downward, the opening of the powder storage bin 3 is turned downward by rotating the handle, thereby completing the feeding and unloading process of the powder cylinder.

[0025] like Figure 1-8As shown, to limit the rotation direction of the powder storage tank 3, a limiting block 11 is provided on the cylinder 1. The limiting block 11 is installed on one side of the handle, and a handle elastic clamp 12 is installed on the limiting block 11. The handle elastic clamp 12 includes two arc-shaped clamps, with a space between them. The inner surface between the two clamps is an arc-shaped surface, and the curvature of the arc-shaped surface is consistent with the outer surface of the handle. The inner arc of the handle elastic clamp 12 is greater than a semicircle, and the axial direction is consistent with the axial direction of the handle after it has been rotated. The clamps are elastic and can rebound after slight deformation. When the handle is rotated to the corresponding position, the handle enters the handle elastic clamp 12 and is positioned and clamped by the handle elastic clamp 12. In this embodiment, the handle elastic clamp 12 restricts the handle to a vertical direction facing upward. When the handle is rotated to the upward direction, the handle enters the handle elastic clamp 12 through the opening of the handle elastic clamp 12, and the handle elastic clamp 12 fixes the position of the handle, thereby fixing the opening of the powder storage tank 3 to face upward, ensuring the stability of feeding material into the upward-facing cylinder. When the powder storage tank 3 needs to be rotated downwards, the handle can be removed from the handle elastic clamp 12. Since the clamp is elastic, the opening of the clamp will deform when force is applied, and the handle can be removed from the handle elastic clamp 12, making it very convenient to adjust the powder storage tank 3.

[0026] like Figure 1-5 As shown, the bottom of the cylinder 1 is equipped with three clips 4, evenly distributed on the bottom plane of the cylinder 1. The three clips 4 are evenly arranged in a circular pattern. Each clip 4 is an arc-shaped strip, with both its inner and outer end faces being arc-shaped. Correspondingly, the upper end of the gypsum vacuum mixer also has a groove corresponding to the clips 4. The correspondence between the three clips 4 and the three grooves determines the installation position of the powder loading cylinder, ensuring simple and direct installation while maintaining installation efficiency and stability. The bottom of the cylinder 1 has an annular groove for engaging with the upper end of the gypsum vacuum mixer. A sealing ring or other sealing material is placed inside to facilitate sealing the gap between the cylinder 1 and the mixer body. This ensures the stability of the gypsum vacuum mixer during vacuuming. The clips 4 are located outside the annular groove to ensure that the clips 4 do not affect the sealing of the powder loading cylinder.

[0027] like Figure 3 , 5 As shown in Figure 7, in this embodiment, the other end of the powder storage tank 3 corresponding to the opening is set as a flat surface, not a spherical arc surface. Therefore, the shape of the powder storage tank 3 is a sphere with two parallel surfaces cut off; one surface is the opening of the powder storage tank 3, and the other is the bottom surface. This shape facilitates the rotation of the powder storage tank 3 due to its overall spherical shape. Furthermore, setting the other end as a flat surface reduces the volume of the inner cavity 31 on the other side. When powder is being added to the powder storage tank 3, the volume of the opening end and the volume of the bottom end of the powder storage tank 3 remain balanced. After the powder is filled into the powder storage tank 3, the imbalance on both sides is avoided, preventing the rotating shaft 32 from receiving unbalanced forces, thus ensuring the service life of the rotating shaft 32 and guaranteeing the stability of rotation.
