The dewatering equipment also needs to pump the separated powder to the conveying equipment. This solution has a large footprint and high cost. In addition, when the dewatering equipment is used for conveying alone, it usually carries a lot of water into the next process conveying equipment, which leads to the need for further dewatering in the subsequent conveying process, increasing the number of processes and equipment.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The powder dehydration and separation device of this utility model includes a stirring assembly 1 and a conveying assembly 2. The stirring assembly 1 includes a stirring tank 11 and a stirring component 12. The stirring component 12 is disposed on the stirring tank 11, and the output end of the stirring component 12 extends into the stirring tank 11. The conveying assembly 2 is connected to the mixing assembly 1 to convey the powder separated by the mixing assembly 1. The conveying assembly 2 includes a conveying pipe 21, a mixing shaft 22, a spiral blade assembly 23, and a driving assembly 24. The conveying pipe 21 is connected to the mixing tank 11, and there is a preset angle between the axial directions of the conveying pipe 21 and the mixing tank 11. The stirring shaft 22 and the spiral blade assembly 23 are partially disposed inside the conveying pipe 21 and the mixing tank 11. The driving component 24 is connected to the stirring shaft 22, and the spiral blade assembly 23 is spirally arranged in the axial direction of the stirring shaft 22. The powder dehydration and separation equipment of this utility model facilitates direct conveying of separated powder without the need for separate dehydration equipment during conveying, thus reducing equipment costs.

[0021] Specifically, such as Figures 1 to 3 As shown, the mixing tank 11 is suitable for receiving the unseparated powder and water from the previous process. The mixing assembly 1 is positioned above the mixing tank 11, with its output end extending into the mixing tank 11 to mix the unseparated powder, facilitating separation of the powder and water. The conveying pipe 21 of the conveying assembly 2 is connected to the mixing tank 11. The stirring shaft 22 is positioned inside the conveying pipe 21, and the driving component 24 is positioned on the conveying pipe 21, with its output end extending into the conveying pipe 21 and connected to the stirring shaft 22 to drive the stirring shaft 22 to rotate. The stirring shaft 22 is spirally provided with a spiral blade component 23, which is suitable for conveying the separated powder into the conveying pipe 21 when the stirring shaft 22 rotates, and the upper end of the conveying pipe 21 can be provided with a discharge port to output the powder.

[0022] The axial direction of the conveying pipe 21 forms a predetermined angle with the extension direction of the mixing tank 11. That is, the extension direction of the mixing tank 11 is vertical, and the height of the left end of the conveying pipe 21 is lower than the height of the right end. Therefore, the conveying pipe 21 gradually slopes upward from left to right. The left end of the conveying pipe 21 is suitable for receiving powder, which is then conveyed upwards. This facilitates the separation of water from the powder under gravity during the upward conveying process. In other words, as the powder is conveyed upwards, the water flows downwards back into the mixing tank 11 due to gravity, and the powder is then conveyed to the next process.

[0023] The powder dewatering and separation equipment of this utility model sets the conveying component 2 on the stirring component 1, so that the powder can be directly conveyed after separation. Due to the inclination of the conveying pipe 21 and the inclination of the stirring shaft 22, when the powder is conveyed upward, the water flows downward back into the equipment due to gravity. The powder is then conveyed to the next process, which facilitates the direct conveying of the powder after separation. There is no need to set up a separate dewatering device during conveying, which reduces the equipment cost. The separation and conveying equipment are combined into one, which reduces the equipment footprint.

[0024] In some embodiments, the helical blade component 23 includes a lower helical blade 231, a middle helical blade 232, and an upper helical blade 233 connected sequentially from bottom to top. The lower helical blade 231 is disposed inside the mixing tank 11, and the upper helical blade 233 is disposed inside the conveying pipe 21. The rotation radius of the lower helical blade 231 is greater than that of the middle helical blade 232, and the rotation radius of the middle helical blade 232 is greater than that of the upper helical blade 233.

[0025] Specifically, such as Figures 1 to 3As shown, the upper end of the lower helical blade 231 is connected to the lower end of the middle helical blade 232, and the upper end of the middle helical blade 232 is connected to the lower end of the upper helical blade 233. Due to the large internal cavity of the equipment, small blades cannot smoothly convey the material into the helical cavity, while larger blades will cause blockage in the helical conveying section. Therefore, the rotation radius of the lower helical blade 231 in the mixing tank 11 is maximized to continue conveying the powder upward. It can be understood that the powder first contacts the lower helical blade 231, initially gathering and feeding it into the helical conveying channel. As the powder moves upward and enters the area of ​​the middle helical blade 232, the blades gradually decrease in size, better conveying the separated powder upward and facilitating the downward flow of water from the conveying pipe 21 between the blades after water separation, reducing the moisture content of the powder and preventing the powder from accumulating in the helical conveying section and causing blockage. Finally, the powder reaches the area of ​​the upper helical blade 233, where the blades further decrease in size, ultimately conveying the powder to the discharge port at the top of the equipment for the next process.

[0026] In some embodiments, the rotation radius of the lower helical blade 231 is 350cm~250cm, the rotation radius of the middle helical blade 232 is 120cm~180cm, and the rotation radius of the upper helical blade 233 is 80cm~120cm.

[0027] Specifically, such as Figures 1 to 3 As shown, the lower helical blade 231 has a larger rotation radius, meaning it can cover a larger area, thus more effectively gathering material from the bottom of the equipment and feeding it into the helical conveyor channel. By gradually reducing the rotation radius, material can be smoothly conveyed from the bottom to the top of the equipment, improving conveying efficiency. The smaller rotation radius of the upper helical blade 233 effectively prevents material accumulation in its area; that is, the powder output per unit time is less with a smaller rotation radius than with a larger rotation radius. Simultaneously, during the upward conveying of powder, reduced stalling ensures stable equipment operation.

[0028] In some embodiments, the lower helical blade 231, the middle helical blade 232, and the upper helical blade 233 are integrally formed to improve structural strength and reduce manufacturing costs.

[0029] In some embodiments, the axial direction of the conveying pipe 21 and the axial direction of the mixing tank 11 have a preset included angle A, and 45°≤A≤75°.

[0030] Specifically, such as Figures 1 to 3As shown, angle A can be 45°, 60°, or 75°. When the material reaches the outlet of the conveying pipe 21, it enters the mixing tank 11 according to the direction of angle A. Different angles A affect the speed and direction of the material entering the mixing tank 11. At a 45° angle, the material enters the mixing tank 11 at a relatively gentle angle, suitable for gentle mixing and powders with low dehydration requirements. At a 60° angle, the material enters the mixing tank 11 at a moderate angle, suitable for most mixing needs and powders with certain dehydration requirements. At a 75° angle, the material enters the mixing tank 11 at a steeper angle, suitable for rapid mixing and powders with high dehydration requirements.

[0031] In some embodiments, the stirring assembly 1 further includes a discharge component 13, which is connected to the bottom of the stirring tank 11. The discharge component 13 includes a first valve 131 and a bent pipe 132. One end of the first valve 131 is connected to the bottom of the stirring tank 11, and the other end of the first valve 131 is connected to the bent pipe 132.

[0032] Specifically, such as Figures 1 to 3 As shown, the first valve 131 is in a normally open mode, meaning it is always open. The first valve 131 connects the bent pipe 132 and the mixing tank 11 to drain water from the mixing pipe and control the liquid level within it. The bent pipe 132 is U-shaped. To control the water level and achieve automatic drainage, a U-shaped drain pipe is installed at the bottom of the mixing pipe. Due to pressure, the water level inside the equipment remains constant. Excess water is automatically drained. The highest point of the U-shaped pipe is located at the intersection of the conveying pipe 21 and the inner wall of the mixing tank 11, ensuring the water level is always at the same position as the highest point of the U-shaped pipe. Excess water is automatically drained to maintain the liquid level.

[0033] Furthermore, the bent pipe 132 includes a first horizontal section 1321, a first vertical section 1322, and a second horizontal section 1323. The inlet of the first horizontal section 1321 is connected to the first valve 131, the outlet of the first horizontal section 1321 is connected to the inlet of the first vertical section 1322, and the outlet of the first vertical section 1322 is connected to the inlet of the second horizontal section 1323. The first vertical segment 1322 extends in the vertical direction, and the first horizontal segment 1321 and the second horizontal segment 1323 extend in the same direction as the first vertical segment 1322. The highest point of the first vertical segment 1322 is at the same position in the vertical direction as the intersection of the conveying pipe 21 and the inner wall of the mixing tank 11.

[0034] In some embodiments, the mixing tank 11 includes a first section 111, a second section 112 and a third section 113 connected sequentially from top to bottom. The radial dimension of the second section 112 gradually decreases from top to bottom so that the powder and water mixture during mixing by the mixing assembly 1 can rotate inside the mixing tank 11, facilitating the separation of powder and water.

[0035] The radial dimension of the first segment 111 remains unchanged. The upper end of the second segment 112 is connected to the first segment 111, and the lower end of the second segment 112 is connected to the third segment 113. The radial dimension of the second segment 112 gradually decreases from top to bottom, which facilitates the rotation and separation of powder and water.

[0036] In some embodiments, the stirring component 12 includes a driving member 121, a stirring plate 122, and stirring rods 123. The driving member 121 is disposed on the stirring tank 11, extends into the stirring tank 11 and is connected to the stirring plate 122. A plurality of spaced-apart stirring rods 123 are disposed below the stirring plate 122. The driving member 121 is located at the upper end of the stirring tank 11, and its output end extends into the stirring tank 11 and is connected to the stirring plate 122. Further, the dimensions of the stirring rods 123 gradually decrease along the direction close to the inner wall of the stirring tank 11 in the extending direction of the stirring tank 11, to match the gradual decrease in radial dimension of the second segment 112 from top to bottom. This prevents the stirring rods 123 from impacting the inner wall of the stirring tank 11.
