Description

Technical Field

[0001] This utility model relates to the field of desulfurized gypsum powder production technology, specifically to a cooling device for desulfurized gypsum powder production. Background Technology

[0002] Desulfurized gypsum powder is an important industrial raw material, widely used in construction, building materials, industrial molds and art models, chemical industry, agriculture, food processing, and pharmaceuticals and cosmetics. It is made from raw gypsum through grinding and calcination. During calcination, all adsorbed water and some crystal water are removed, transforming it into gypsum. The temperature of the calcined gypsum powder reaches approximately 170℃. Therefore, cooling measures must be taken during the production of desulfurized gypsum powder, and the powder must be stored in a warehouse for aging to ensure its quality and stability.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 220771459 U), "a desulfurized gypsum powder cooling device includes a box, a rotating rod and a stirring blade. The rotating rod is rotatably disposed inside the box. The stirring blade is equidistantly disposed on both sides of the rotating rod. A cleaning plate is disposed at one end of the stirring blade. A cleaning assembly is disposed inside the cleaning plate. The cleaning assembly includes a receiving groove, a base plate and a brush. Two pushing components are symmetrically disposed between the bottom of the base plate and the cleaning plate. Two guiding components are symmetrically disposed between the two ends of the base plate and the inner wall of the receiving groove."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model utilizes a structure including a cleaning plate, a receiving tank, a base plate, a brush, a protective box, a mounting block, and a pushing cylinder. A rotating rod drives the cleaning plate to rotate, facilitating the movement of the brush to clean the gypsum powder adhering to the inner wall of the chamber. This allows the gypsum powder to fall to the bottom of the chamber and be discharged from the outlet, reducing material waste. However, in actual use, the device directly feeds a large amount of gypsum powder into the chamber at once, resulting in uneven distribution of the desulfurized gypsum powder within the cooling device. This leads to gypsum powder accumulation inside the chamber, affecting the efficiency of the heat dissipation and stirring components. Consequently, the heat in the gypsum powder cannot dissipate quickly, significantly reducing the cooling effect. Therefore, an improved cooling device for desulfurized gypsum powder production is needed. Utility Model Content

[0018] 2. This cooling device for desulfurized gypsum powder production uses an air outlet mechanism. By starting motor two, the motor two drives the rotating fan blades to quickly extract the hot air from the cooling box, thereby further accelerating the airflow inside the cooling box and improving the cooling effect.

[0029] The existing technology involves feeding a large amount of gypsum powder directly into the chamber at once, resulting in uneven distribution of the desulfurized gypsum powder within the cooling device. This leads to gypsum powder accumulation inside the chamber, affecting the efficiency of the heat dissipation and stirring components. Consequently, the heat from the gypsum powder cannot dissipate quickly, significantly reducing the cooling effect. Please refer to [link to relevant documentation].

[0030] The feeding and mixing mechanism 4 includes a feeding component 41 and a mixing component 42, with the mixing component 42 disposed at the bottom of the feeding component 41;

[0031] The feeding assembly 41 includes a fixed frame 411, which is fixedly connected to the top of the feeding hopper 3. A motor 412 is fixedly connected to the top of the fixed frame 411. A gear 413 is fixedly connected to the output end of the motor 412. A gear 414 meshes with the left side of the gear 413. A rotating sleeve 415 is fixedly connected inside the gear 414. A spiral conveying blade 416 is fixedly connected to the outside of the rotating sleeve 415. A stirring frame 417 is fixedly connected to the left and right sides of the rotating sleeve 415 to facilitate control of the feeding speed and ensure uniform feeding.

[0032] Furthermore, gear 414 is rotatably connected inside the fixed frame 411, and rotating sleeve 415 is rotatably connected inside the fixed frame 411, which facilitates the rotation of rotating sleeve 415.

[0033] Furthermore, the stirring assembly 42 includes a connecting column 421, which is fixedly connected inside the fixed frame 411. A first bevel gear 422 is fixedly connected to the bottom of the connecting column 421. A second bevel gear 423 meshes with the left and right sides of the first bevel gear 422. A stirring blade 424 is fixedly connected to the outside of the second bevel gear 423. A fixed sleeve 425 is fixedly connected to the bottom of the rotating sleeve 415, which facilitates the uniform dispersion of the desulfurized gypsum powder and improves its heat dissipation effect.

[0034] Furthermore, the fixed sleeve 425 has a hole at the corresponding position of the second bevel gear 423, and the second bevel gear 423 is rotatably connected in the hole, which facilitates the rotation of the stirring blade 424.

[0035] Furthermore, a hole is provided at the corresponding position of the rotating sleeve 415 and the connecting post 421, and the rotating sleeve 415 is rotatably connected in the hole, so as to facilitate the stable rotation of the rotating sleeve 415. Example

[0036] Based on the existing technology, there is a problem with the need to exhaust hot air from the enclosure. Please refer to [link / reference]. Figure 6 Furthermore, in conjunction with Embodiment 1, the air outlet mechanism 5 includes an air outlet frame 51, which is fixedly connected to the right side of the cooling box 1. A fixing plate 52 is fixedly connected to the right side of the air outlet frame 51, and a second motor 53 is fixedly connected to the right side of the fixing plate 52. A rotating fan blade 54 is fixedly connected to the outside of the output end of the second motor 53, and a cleaning brush 55 is fixedly connected to the output end of the second motor 53. A filter plate 56 is fixedly connected inside the air outlet frame 51 to facilitate the extraction of hot air from the cooling box 1.

[0037] Furthermore, the right side of the cleaning brush 55 abuts against the left side of the filter plate 56, and the air outlet frame 51 has a groove at the corresponding position of the filter plate 56, and the fixing plate 52 is fixedly connected in the groove, which facilitates cleaning the filter plate 56.

[0038] In actual operation, when the device is in use, firstly, the desulfurized gypsum powder is put into the feed hopper 3. The feeding and stirring mechanism 4 is activated, and motor 412 is started. Motor 412 drives gear 413 to rotate, which in turn drives gear 414 to rotate. Gear 414 then synchronously drives the rotating sleeve 415 to rotate. During the rotation of the rotating sleeve 415, the spiral conveyor blades 416 rotate, allowing the desulfurized gypsum powder to be evenly conveyed to the bottom of the cooling box 1 via the spiral conveyor blades 416. Simultaneously, the rotating sleeve 415 drives the stirring frame 417 to rotate, allowing the outer side of the stirring frame 417 to scrape the inner wall of the cooling box 1, preventing efflorescence. As the sulfurized gypsum powder adheres, the rotating sleeve 415 rotates synchronously, driving the fixed sleeve 425 to rotate as well. This causes the fixed sleeve 425 to simultaneously drive the two bevel gears to rotate. As the second bevel gear 423 rotates, it meshes with the first bevel gear 422, thus synchronously driving the stirring blade 424 to rotate. This effectively disperses the desulfurized gypsum powder. Simultaneously, cold air is introduced through the air inlet to achieve cooling. Then, through the set air outlet mechanism 5, the second motor 53 is started, driving the rotating fan blade 54 to rotate, thereby quickly extracting the hot air from the cooling box 1.
