Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate calcination, and in particular to a calcination device for calcium carbonate raw materials. Background Technology

[0002] The main filler used in offset printing inks is calcium carbonate. With the upgrading of printing machinery and equipment and the improvement of printing technology, the printing speed per sheet has increased from several thousand sheets per hour to more than 20,000 sheets per hour. This has placed higher demands on the quality of offset printing inks. In addition to having a certain color concentration, high transparency and gloss, and suitable viscosity and flowability, they must also have anti-emulsification, anti-ink splatter, and drying balance in high-speed printing. However, traditional calcium carbonate fillers can no longer fully meet the quality requirements of high-speed printing inks. Now, high-transparency offset printing inks using nano-level calcium carbonate after process modification are often used as raw materials.

[0003] Currently, limestone calcination is carried out using traditional methods, with coal or gas as fuel to calcine raw materials such as limestone. During the process, when the limestone is poured into the calcination container, dust is easily generated, which causes air pollution, affects visibility, and also affects the entire construction environment. Utility Model Content

[0004] One objective of this invention is to provide a calcination apparatus for calcium carbonate raw materials that at least solves any of the aforementioned technical problems.

[0005] A further objective of this invention is to avoid the impact of residual powder mixed in with limestone on the construction field of vision, and at the same time to avoid dust pollution of the environment.

[0006] Another further objective of this invention is to improve the construction environment.

[0007] In particular, this utility model provides a calcination device for calcium carbonate raw materials, including a base, the base having a receiving cavity;

[0008] The tank body is disposed on the upper part of the base, and the upper part of the tank body is provided with a feed inlet and a dust suction port;

[0009] A spiral feeder plate is disposed inside the tank and is fixedly connected to a rotating shaft;

[0010] An air blowing section is provided within the receiving cavity of the base, and the air blowing section communicates with the interior of the tank.

[0011] A first bevel gear and a second bevel gear mesh, with the first bevel gear fixedly connected to the rotating shaft and the second bevel gear connected to the drive motor.

[0012] Furthermore, a mesh cover is provided inside the tank, and an air outlet is provided below the mesh cover, with the air outlet opening towards the mesh cover.

[0013] Furthermore, the spiral feed plate is provided with a plurality of air vents arranged in an array.

[0014] Furthermore, the second bevel gear is a partial gear.

[0015] Furthermore, a torsion spring is sleeved on the rotating shaft, and one end of the torsion spring is fixedly connected to the inner wall of the base, while the other end of the torsion spring is fixedly connected to the rotating shaft.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a spiral feeding plate installed inside the tank for feeding limestone. The spiral feeding plate is fixedly connected to a rotating shaft, which assists in feeding the limestone downwards. Simultaneously, an air blowing unit blows air into the tank through an outlet and through the air vents of the spiral feeding plate. Air is then drawn in through a dust suction port, and dust particles generated are blown upwards through a lower outlet and then sucked in through the dust suction port. A drive motor drives a second bevel gear to rotate a first bevel gear. Because the second bevel gear is a partial gear, it intermittently drives the first bevel gear during rotation, thus rotating the spiral feeding plate. As the spiral feeding plate rotates, it causes the limestone on it to deflect and slide off. A torsion spring is installed on the rotating shaft, which resets the spiral feeding plate and shakes off dust from the limestone, facilitating air blowing from the outlet and dust suction.

[0025] This embodiment provides a calcination device for calcium carbonate raw materials, such as... Figures 1 to 3 As shown, the structure includes a base 1, a tank 2, a spiral feed plate 6, an air blowing section 5, a first bevel gear 10, and a second bevel gear 11. The base 1 has a receiving cavity; the tank 2 is disposed on the upper part of the base 1, and has a discharge port 201 on one side, and a feed inlet 4 and a dust suction port 3 are provided on the upper part of the tank 2; the spiral feed plate 6 is disposed inside the tank 2, and is fixedly connected to a rotating shaft 13; the air blowing section is disposed inside the receiving cavity of the base 1, and the air blowing section 5 communicates with the interior of the tank 2; the first bevel gear 10... The first bevel gear 10 meshes with the second bevel gear 11, and the first bevel gear 10 is fixedly connected to the rotating shaft 13. The second bevel gear 11 is connected to the drive motor 12. A mesh cover 7 is provided inside the tank body 2, and an air outlet 8 is provided below the mesh cover 7. The air outlet 8 opens towards the mesh cover 7. A plurality of arrayed ventilation holes 601 are provided on the spiral feed plate 6. The second bevel gear 11 is a partial gear. A torsion spring 9 is sleeved on the rotating shaft 13, and one end of the torsion spring 9 is fixedly connected to the inner wall of the base 1, and the other end of the torsion spring 9 is fixedly connected to the rotating shaft 13.

[0026] Working principle of this utility model:

[0027] In use, a spiral feeding plate 6 is installed inside the tank body 2 to feed the limestone. The spiral feeding plate 6 is fixedly connected to the rotating shaft 13. The rotation of the rotating shaft 13 assists in feeding the limestone downwards. At the same time, the air blowing unit 5 blows air into the tank body 2 through the air outlet 8 and through the air vents 601 of the spiral feeding plate 6. Air is then drawn in through the dust suction port 3. The dust particles generated are blown upwards through the lower air outlet 8 and then sucked in through the dust suction port 3. Simultaneously, the drive motor 12 drives the second bevel gear 11. The first bevel gear 10 is driven to rotate. Since the second bevel gear 11 is a partial gear, it can intermittently drive the first bevel gear 10 when rotating, thereby causing the spiral feed plate 6 to rotate. When the spiral feed plate 6 rotates, it can cause the limestone on the spiral feed plate 6 to deflect and slide off. At the same time, a torsion spring 9 is provided on the rotating shaft 13. The spiral feed plate 6 is reset by the drive of the torsion spring 9. At the same time, it can shake off the dust on the limestone, so that the air outlet 8 can blow it up and the dust suction port 3 can suck up the dust.

[0028] 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.
