Description

Technical Field

[0001] This utility model relates to the field of feeding devices, and in particular to a feeding device for the production of light calcium carbonate. Background Technology

[0002] Light calcium carbonate, also known as precipitated calcium carbonate, is a type of light calcium carbonate. It is used as a filler in industries such as rubber, plastics, papermaking, coatings, and inks. It is also widely used in organic synthesis, metallurgy, glass, and asbestos production.

[0003] Calcium production generally uses limestone as the main raw material, which is refined through decomposition, combination and other reactions. In the production of light calcium carbonate, a feeding device is required to feed the raw material.

[0004] A publicly available patent document (CN221092600U) discloses a feeding device for light calcium carbonate production, including a temporary storage component, a mounting frame, and a drive component. The mounting frame adopts a frame structure with a cavity at its center. The temporary storage component is located within the cavity, and the drive component controls the lifting and lowering of the temporary storage component within the cavity. A conveying device feeds materials from the feeding end into the temporary storage component, and the drive component then controls the temporary storage component to perform feeding. This invention, by setting up a temporary storage component, allows the materials conveyed by the conveying device to automatically fall into the temporary storage component. Once the temporary storage component is full of raw materials, the drive component controls the temporary storage component to rise, allowing it to perform feeding within the cavity of the mounting frame. The mounting frame provides protection for the temporary storage component, and also prevents materials from falling during the feeding process, eliminating safety hazards.

[0005] Although the aforementioned document describes the use of mounting brackets to prevent falling materials, after the hopper is loaded, or during the loading process when loose material falls into the cavity where the hopper is placed, it is difficult to level the hopper after it falls. This makes it difficult to align the hopper's feed buckle with the discharge plate, thus preventing the hopper from collecting materials conveyed by the conveyor belt. Utility Model Content

[0006] One objective of this invention is to provide a feeding device for the production of light calcium carbonate that at least solves one of the aforementioned technical problems.

[0007] A further objective of this invention is to avoid the situation where loose material falls into the hopper placement cavity and is difficult to clean.

[0008] Another further objective of this invention is to improve the collection efficiency and reduce the frequency of cleaning the hopper placement chamber.

[0009] Specifically, this utility model provides a feeding device for the production of light calcium carbonate, comprising, A base, wherein a conveyor belt is provided on the upper part of the base, and a hopper placement cavity is provided at one end of the conveyor belt that penetrates the base; A protective structure is provided at the lower part of the base and is located at the lower part of the hopper placement cavity.

[0010] Furthermore, the protective structure includes: The collection plates are symmetrically arranged, with one end of each collection plate connected to the base via a hinge shaft, and a torsion spring is provided inside the hinge shaft.

[0011] Furthermore, the cross-section of the combined two symmetrical collecting plates is trapezoidal.

[0012] Furthermore, a protective frame is provided above the hopper, and a reinforcing beam is provided on the outer periphery of the protective frame, and the protective frame is inclined.

[0013] Furthermore, an inclined guide plate is provided between the hopper placement cavity and the conveyor belt.

[0014] The technical effects and advantages of this utility model are as follows: This invention features a hopper placement cavity on the base, extending vertically through the base. A protective structure is provided at the lower opening of the placement cavity to prevent loose material from falling into the cavity, thus ensuring the hopper can be placed for collection. During use, if loose material falls into the placement cavity while the hopper is rising, it falls directly onto a collecting plate, which catches the falling material and prevents it from scattering. When the hopper has finished emptying and falls back into the placement cavity, the bottom of the hopper pushes against the loose material and moves downwards. After moving a certain distance, the collecting plate opens under pressure, allowing the material to fall and be collected, thus reducing the falling distance, preventing dust, and ensuring the hopper can be placed correctly.

[0024] Example 1: As Figures 1-6As shown, a feeding device for light calcium carbonate production includes a base 1. A conveyor belt 3 is mounted on the upper part of the base 1 and is installed on the support frame 2 to transport light calcium carbonate raw materials forward. At the end of the conveyor belt 3, i.e., the discharge end, a hopper placement cavity 101 is provided through the base 1 to accommodate and position hoppers 7. The hoppers 7 are lifted and lowered within the hopper placement cavity 101 by a lifting mechanism such as a wire rope 9 to complete the material receiving and feeding process. At the lower part of the base 1, directly opposite the lower opening of the hopper placement cavity 101, a protective structure 8 is provided. This protective structure 8 mainly includes a fixing ring 803 and two symmetrically arranged collecting plates 801. One end of the collecting plates 801 is hinged to the fixing ring 803 at the bottom of the base 1 via a hinge shaft 802. The hinge shaft 802 is equipped with a torsion spring. It should be noted that the torsion spring is not shown in the figure, but it is a conventional technique in the field. This allows the two collecting plates 801 to remain in a combined state under the action of the torsion spring in their natural state. The cross-section of the combined plate is preferably trapezoidal, forming a funnel-shaped temporary support surface.

[0025] Working process and principle: When hopper 7 rises in hopper placement cavity 101 to feed material, some loose material may spill out of hopper 7. This loose material will fall through hopper placement cavity 101. At this time, since the collecting plate 801 is in a closed state, the loose material will fall on the temporary support surface formed by the collecting plate 801 and be effectively collected, instead of falling directly to the ground and causing pollution and waste. At the same time, it also avoids the loose material accumulating at the bottom of hopper placement cavity 101, which would affect the stable placement of hopper 7 when it falls back down.

[0026] When hopper 7 finishes loading and falls back into hopper placement cavity 101, the bottom of hopper 7 gradually contacts and presses against the loose material supported by collection plate 801. As hopper 7 continues to descend, its downward pressure overcomes the torque of the torsion spring inside hinge shaft 802, forcing the two collection plates 801 to rotate outward around hinge shaft 802 and open. The loose material on collection plate 801 then falls through the opening and can be caught by the collection container (such as a trolley, material frame, etc.) set below. Hopper 7 can then fall smoothly and steadily back to the predetermined position of hopper placement cavity 101. After hopper 7 is in place, the pressure on collection plate 801 disappears, and under the action of the torsion spring, the two collection plates 801 automatically reset to the combined state, ready to receive the next batch of loose material.

[0027] Example 2: Based on Example 1, to further optimize the structure, such as... Figure 1 , Figure 4 and Figure 5As shown, a protective frame 5 is installed above the hopper 7. Reinforcing beams 6 are installed around the outer perimeter of the protective frame 5 to enhance its structural strength. The protective frame 5 is preferably inclined, with its inclination angle adapted to the tilting angle of the hopper 7 during loading. The function of the protective frame 5 is to protect the hopper 7 and its surrounding area when the hopper 7 is raised to the loading position for tilting, preventing material from splashing out of the device during the tilting process, further improving the working environment and enhancing safety.

[0028] Example 3: Based on Example 1 or 2, such as Figure 1 , Figure 2 and Figure 5 As shown, an inclined guide plate 4 is provided between the hopper placement chamber 101 and the discharge end of the conveyor belt 3. One end of the guide plate 4 is connected to the discharge end of the conveyor belt 3, and the other end extends above the hopper placement chamber 101. Its function is to guide the material conveyed from the conveyor belt 3 to fall more accurately and centrally into the hopper 7 located in the hopper placement chamber 101, reducing the possible spillage and leakage of material at the end of the conveyor belt, and reducing the generation of loose material from the source.

[0029] Working principle of this utility model: In use, a hopper placement cavity is provided on the base, extending vertically through the base. A protective structure is provided at the lower opening of the placement cavity to prevent loose material from falling into the cavity, thus ensuring the hopper can be placed for collection. During use, if loose material falls into the placement cavity while the hopper is rising, it falls directly onto the collection plate, which catches the falling material and prevents it from scattering. When the hopper has finished emptying and falls back into the placement cavity, the bottom of the hopper pushes against the loose material and moves downwards. After moving a certain distance, the collection plate opens under pressure, allowing the material to fall and be collected, thus reducing the falling distance, preventing dust, and ensuring the hopper can be placed correctly.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
