Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for calcium carbonate powder. Background Technology
[0002] Calcium carbonate is an important type of functional inorganic filler with advantages such as low price, abundant reserves, stable performance, easy processing, and non-toxicity. It can significantly improve the processing performance and physical properties of materials and reduce production costs. It is widely used in plastics, rubber, coatings, papermaking and other fields. Calcium carbonate powder is an inorganic compound powder with the chemical formula CaCO3. It is the main component of natural minerals such as limestone, marble, and calcite, and is also an important basic material in industrial production. However, because calcium carbonate powder contains large lumps, these large pieces of calcium carbonate powder cannot be completely dried during drying. In addition, calcium carbonate powder will agglomerate during the drying process, which will affect the drying effect. Utility Model Content

Mounting grooves are fixedly opened on the inner walls of both sides of the drying chamber. Four springs are fixedly installed at the bottom of the four corners of the mounting grooves. A placement plate is fixedly connected to the upper end of each of the four springs. A pressing assembly is fixedly installed on the outer surface of one side of the drying chamber. The pressing assembly can press the placement plate, causing the calcium carbonate powder on the placement plate to tumble up and down under the action of the springs. A hot air drying assembly is fixedly installed on the same side of the drying chamber as the pressing assembly.

[0012] The beneficial effects of this utility model are as follows: This utility model adopts a pressing component, which presses the placement plate by pressing the pressing block, causing the calcium carbonate powder on the placement plate to roll up and down under the action of the spring, preventing the calcium carbonate powder from agglomerating during the drying process.

[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] like Figures 1-6 As shown, this embodiment provides a drying device for calcium carbonate powder, including a drying chamber 1. A feed inlet 2 is fixedly installed at the upper end of the drying chamber 1. Mounting grooves 3 are fixedly opened on the inner walls of both sides of the drying chamber 1. Four springs 4 are fixedly installed at the bottom of the four corners of the mounting grooves 3. Placement plates 5 are fixedly connected to the upper ends of the four springs 4. A pressing component 6 is fixedly installed on the outer surface of one side of the drying chamber 1. A hot air drying component 7 is fixedly installed on the same side of the drying chamber 1 as the pressing component 6. In use, calcium carbonate powder is first put into the drying chamber 1 through the feed inlet 2. The material falls onto the placement plate 5. The hot air drying component 7 is started to introduce hot air into the drying chamber 1 to dry the calcium carbonate powder. During the drying process, the pressing component 6 is started. The pressing component 6 periodically applies pressure to the placement plate 5. After the placement plate 5 is pressed, the springs 4 are compressed and move downward. After the pressure is released, the springs 4 rebound and the placement plate 5 rises. This is repeated to make the calcium carbonate powder on the placement plate 5 constantly turn over, preventing the calcium carbonate powder from agglomerating and improving the drying effect and efficiency.
[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 1 and Figure 2As shown, two partition plates 9 are installed inside the drying chamber 1, and a hot air guide plate 8 is set between the two partition plates 9. A sieve plate 10 is slidably installed in the discharge port 2. The placement plate 5 is movably snapped into the mounting groove 3. The two partition plates 9 are fixedly installed on the upper surface of the placement plate 5 and are slidably connected to the inner wall of the drying chamber 1. The inclined end of the hot air guide plate 8 is fixedly connected to the upper surface of the placement plate 5. There are two pressing components 6, and the two pressing components 6 are respectively set on one side of the two partition plates 9. The sieve plate 10 in the discharge port 2 can screen the calcium carbonate powder and screen out the larger calcium carbonate powder. The hot air is guided by the hot air guide plate 8 and blown towards the calcium carbonate powder on the placement plate 5. The two partition plates 9 can also prevent the calcium carbonate powder on the placement plate 5 from entering the working area of the pressing component 6.
[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 3 As shown, the pressing component 6 includes a motor 601, one end of which is fixedly connected to a rotating shaft 602. A rotating roller 603 is fixedly mounted on the surface of the rotating shaft 602, and pressing blocks 604 are arrayed on the surface of the rotating roller 603. The output shaft of the motor 601 is fixedly connected to the rotating shaft 602, and the motor 601 is fixedly mounted on one side of the outer surface of the drying oven 1. The pressing blocks 604 are in direct contact with the placement plate 5. The output shaft of the motor 601 drives the rotating shaft 602 to rotate, which in turn causes the rotating roller 603 to rotate. The pressing blocks 604 on the surface of the rotating roller 603 rotate accordingly. When the pressing blocks 604 rotate to contact the placement plate 5, they apply pressure to the placement plate 5, causing it to move downward. After moving away, the placement plate 5 rebounds. This repeated vibration allows the calcium carbonate powder to be fully agitated, preventing the calcium carbonate powder from agglomerating.
[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 4 and Figure 5As shown, the hot air drying assembly 7 includes an exhaust fan 701. A connecting rod 702 is fixedly installed on one side of the exhaust fan 701. An exhaust pipe 703 is fixedly connected to the upper end of the exhaust fan 701. A heating box 704 is fixedly connected to the other end of the exhaust pipe 703. A heating resistance wire 706 is fixedly installed inside the heating box 704. Hot air nozzles 705 are arranged in an array on one side of the heating box 704. The exhaust fan 701 is fixedly connected to the drying chamber 1 via the connecting rod 702. The heating box 704 is fixedly installed on the inner wall of one side of the drying chamber 1. The hot air nozzles 705 are positioned opposite to the hot air guide plate 8. The heating is activated upon startup. The air drying assembly 7 and the exhaust fan 701 are stably fixed to the drying chamber 1 via the connecting rod 702. When turned on, the exhaust fan starts to draw in outside air through the exhaust pipe 703 into the heating box 704. The heating resistance wire 706 inside the heating box 704 is energized and heats up, rapidly heating the incoming air and converting it into hot air. Subsequently, the hot air is ejected through the array of hot air nozzles 705. Since the hot air nozzles 705 are positioned opposite the hot air guide plate 8, the hot air can accurately flow along the hot air guide plate 8 and blow onto the calcium carbonate powder in the drying chamber 1, thus efficiently drying the calcium carbonate powder and improving the drying effect and speed.
