Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a raw material transfer device for production and processing of calcium carbonate. Background Art

[0002] In the production and processing of powdered or granular raw materials such as calcium carbonate, the transportation of raw materials is a crucial link. Traditional raw material transportation devices mostly adopt a shell structure. The raw materials are injected into the shell through the feed port, and then an impeller is used as a discharge mechanism. The raw materials are discharged from the bottom of the shell through the rotation of the impeller. A Chinese authorized patent (Announcement No.: CN205151241U) discloses a calcium carbonate transportation and storage device, which includes a welded base and a weighing base with a built-in weighing sensor. The motor drives the impeller to rotate through the transmission shaft to discharge the raw materials in the shell through the material blocking assembly. However, this device still has certain defects during use and needs to be improved.

[0003] When using existing raw material transfer devices, the impeller often fails to ensure complete discharge of raw materials. This is because the calcium carbonate raw material may adhere to the inner wall or corners of the housing during transportation, especially when the particles are fine or adhesive. These raw materials trapped in the cracks or edges are difficult to be effectively moved by the rotating impeller, resulting in an increase in residual material in the housing, which not only affects production efficiency but also increases the difficulty and cost of cleanup. Utility Model Content

[0004] The purpose of the utility model is to provide a raw material transfer device for the production and processing of calcium carbonate, which can completely discharge the material at the bottom of the shell through the provided L-shaped plate and wedge-shaped plate, thereby solving the problem that the raw materials on the inner wall or corners of the shell are difficult to be discharged.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a raw material transfer device for the production and processing of calcium carbonate, comprising a shell. Wedge plates are installed inside the shell. The number of the wedge plates is two. The two wedge plates cooperate to form a material guide port. The bottoms of the two wedge plates are provided with mounting grooves. A moving block is slidably fitted in the mounting grooves. A threaded hole is provided in the moving block. A screw is threaded in the threaded hole. An L-shaped plate is installed at the bottom of the moving block.

[0007] An inclined surface is provided on the L-shaped plate, and sponge pads are installed on both sides of the L-shaped plate. A wedge block is installed on the side wall of the shell, and the wedge block is connected to the outer surfaces of the two wedge plates. A block belt is installed in the middle of the L-shaped plate, and a movable groove is provided between the two wedge plates. The block belt slides in the movable groove, and the top of the block belt touches the bottom of the wedge block.

[0008] Furthermore, a slider is slidably fitted in the other movable groove, a sliding hole is provided in the slider, a sliding rod is installed in the movable groove, and the sliding rod is slidably fitted in the sliding hole.

[0009] Furthermore, a restraining plate is installed on the outer surface of the shell, and the retaining belt is fitted in the restraining plate.

[0010] Furthermore, a discharge port and a limiting groove are provided at the bottom of the side plate of the shell. The limiting groove is connected to the discharge port, and the discharge port corresponds to the position of the L-shaped plate.

[0011] Furthermore, a clearance groove is provided in the side plate of the shell, the clearance groove is connected to the discharge port, a baffle is slidably fitted in the clearance groove, and a transverse block is installed on the baffle.

[0012] Furthermore, the bottom of the baffle is fitted in the limiting groove.

[0013] The utility model has the following beneficial effects:

[0014] The utility model discharges the raw materials at the bottom of the shell through the wedge-shaped plate and the L-shaped plate, thereby effectively pushing and peeling off the raw materials attached to the inner wall and corner areas of the shell, ensuring that both fine powder particles and adhesive materials can be completely removed, thereby avoiding the residue and waste of raw materials, thereby solving the problem of raw material residue. The inner wall of the shell and the discharge port are not easily blocked, reducing the equipment downtime caused by cleaning residual materials, and also reducing the difficulty and cost of cleaning work, thereby extending the service life of the equipment;

[0015] The utility model blocks the raw materials by the provided blocking belt and movable groove, which can prevent the raw materials at the top of the shell from falling to the side of the L-shaped plate close to the wedge block, resulting in the raw materials being clamped between the L-shaped plate and the inner wall of the shell when the L-shaped plate is retracted, thereby preventing the raw materials from being unable to be discharged, thereby increasing production efficiency, ensuring the continuity and stability of the production line, avoiding production interruptions or quality fluctuations due to raw material residue, and thus improving overall production efficiency and product quality.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A threaded hole is provided in the moving block 3, and a screw 4 is threaded in the threaded hole. An L-shaped plate 5 is installed at the bottom of the moving block 3. After opening the top cover 101 and injecting the raw material into the shell 1, the raw material is injected into the shell 1 through the bottom of the shell 1. The universal wheels transport the shell 1 to the designated position. When discharging, the raw materials pass through the two wedge plates 2 and cooperate with the wedge block 6 to guide the materials to the bottom of the shell 1. At this time, the horizontal block 11 is pulled toward the top to move the baffle 10 from the limit groove 105 to the make way groove 103 to open the discharge port 104. Then the motor is started to drive the screw 4 to rotate, and the L-shaped plate 5 is driven by the moving block 3 to discharge the raw materials from the bottom of the shell 1 through the discharge port 104.
