[0002] Screening of pre-melted calcium aluminate powder is a crucial step in the production process. The purpose of screening is to remove impurities, including large pieces, unreacted raw material particles, and other foreign matter, thereby improving product purity, controlling particle size, and ensuring the calcium aluminate powder reaches the required particle size range to meet the particle size requirements of different applications. For example, in water purification agent production, a suitable particle size helps improve reaction efficiency and product quality.

[0003] A search revealed Chinese Patent Publication No. CN 214346950 U, which discloses a calcium aluminate powder screening device. The device includes a screening box with a rotating shaft inside. Multiple sets of connecting rods are symmetrically arranged in the middle of the shaft, and a set of lifting plates are located at the bottom.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a pre-melted calcium aluminate powder screening device. For example... Figure 1As shown, the screen includes a base plate 1, on the upper surface of which a screening box 2 is fixedly mounted. A first discharge pipe 3 and a second discharge pipe 6 are respectively mounted on the front and rear sides of the screening box 2. The first discharge pipe 3 is located below the screening plate 9, and the second discharge pipe 6 is located above the screening plate 9. The two discharge pipes allow pre-melted calcium aluminate powder of different sizes to be concentrated in different locations, preventing over-mixing. A feed hopper 7 is fixedly mounted on the top of the screening box 2. The feed hopper 7 is funnel-shaped, facilitating the entry of pre-melted calcium aluminate powder. An inspection port is fixedly mounted on the bottom left side of the screening box 2, allowing for easy inspection of the interior and preventing blockages after prolonged operation.

[0024] Please see Figure 2 and Figure 3 Both the first discharge pipe 3 and the second discharge pipe 6 are equipped with auger shafts 18. The rotation of the auger shafts 18 facilitates the transport of pre-melted calcium aluminate powder from the discharge pipes. The surface of the auger shafts 18 is provided with through holes to allow small-sized pre-melted calcium aluminate powder particles to fall into the screening box 2. An extension plate 8 is provided at the discharge port at the top of the second discharge pipe 6 to prevent the pre-melted calcium aluminate powder from falling around the screening box 2 during discharge, thus facilitating the collection of the pre-melted calcium aluminate powder. The top of the first discharge pipe 3 is provided with a corner pipe to facilitate the bagging of smaller pre-melted calcium aluminate powder particles that have been screened out.

[0025] Please see Figure 2 An inner plate 10 is rotatably mounted on one side of the top of the inner wall of the screening box 2 via a rotating rod. The inclination angle of the inner plate 10 is the same as that of the screening plate 9. The feed hopper 7 is located above the screening plate 9. The width of the inner plate 10 is the same as the width of the internal sliding groove 16 of the screening plate 9. The inner plate 10 and the screening plate 9 are both set with the same inclination angle to facilitate the downward sliding of pre-melted calcium aluminate powder particles and prevent the pre-melted calcium aluminate powder from accumulating on the top of the screening plate 9. The end of the inner plate 10 away from the inner wall of the screening box 2 is slidably fitted with the screening plate 9. The bottom edge of the screening plate 9 slides in contact with the bottom of the inner wall of the screening box 2. The surface of the screening plate 9 is provided with through holes to facilitate the downward falling of small-sized pre-melted calcium aluminate powder. The length of the sliding groove 16 at the left end of the screening plate 9 is greater than the rotation trajectory of the rotating plate 17. The screening plate 9 is set at a 30-degree angle to prevent the accumulation of pre-melted calcium aluminate powder during screening.

[0026] Please see Figure 2 and Figure 4A groove 16 is provided near the left end of the screening plate 9. A rotating plate 17 is rotatably installed on the inner wall of one end of the groove 16. A pressure rod 19 is fixedly installed on the top of the rotating plate 17. A power slide rod 5 is fixedly installed on the top of the pressure rod 19. The power slide rod 5 is shaped like an "n". The two ends of the "n" shape of the power slide rod 5 are slidably inserted into the top of the screening box 2 and the power box 4, respectively. A spring is sleeved on the surface of the power slide rod 5 located inside the power box 4. The "n" shaped power slide rod 5 facilitates sliding on the top of the power box 4 and the screening box 2. In the static state, the support plate 12 and the pressure rod 19 are horizontal. The pressure rod 19 can move up and down through the "n" shaped power slide rod 5. The end of the power slide rod 5 away from the pressure rod 19 passes through the top of the screening box 2 and is slidably inserted into the top of the power box 4. One side of the power box 4 is fixedly installed on the top left side of the screening box 2.

[0027] Please see Figure 2 A support plate 12 is fixedly installed at the bottom of the power slide rod 5. An eccentric wheel 15 is slidably installed on the arc-shaped surface at the bottom of the support plate 12. The connection between the eccentric wheel 15 and the output shaft of the motor 13 is located at halfway away from the center of the eccentric wheel 15. The width of the eccentric wheel 15 is smaller than the width of the support plate 12. The part of the eccentric wheel 15 away from the center is sleeved with the output shaft of the motor 13, so that the outer support plate 12 can move up and down under the action of the rotation of the eccentric wheel 15.

[0028] Please see Figure 2 The eccentric wheel 15 is sleeved on the outer circumferential surface of the output shaft on one side of the motor 13. A support column 14 is fixedly installed at the bottom of the motor 13. The bottom of the support column 14 is fixedly installed on one side of the inner wall of the power box 4 through a connecting plate. A limit plate 11 is slidably sleeved on the left side of the power slide rod 5. One end of the limit plate 11 is fixedly installed on one side of the inner wall of the power box 4.

[0029] The implementation principle of the pre-melted calcium aluminate powder screening device in this application embodiment is as follows: During use, pre-melted calcium aluminate powder is fed into the screening box 2 through the feed hopper 7. As the pre-melted calcium aluminate powder falls, it contacts the upper surface of the screening plate 9. Smaller pre-melted calcium aluminate powder particles fall below the screening plate 9, while larger particles slide to the bottom position above the screening plate 9. During the falling process, the motor 13 is activated to drive the eccentric wheel 15 to rotate. The eccentric wheel 15, through the support plate 12, causes the power slide rod 5 to move rapidly up and down. The power slide rod 5, through the pressure rod 19 and the rotating plate 17 below, drives the screening plate. 9 moves upward. Since the top of the screening plate 9 is slidably connected to the inner plate 10, and the top position of the inner plate 10 is fixed, the screening plate 9 can only rotate through the rotating rod at the top of the inner plate 10. When it swings up and down, it achieves a vibration effect, which promotes the pre-melted calcium aluminate powder on the surface of the screening plate 9 to achieve the effect of vibration screening, preventing the pre-melted calcium aluminate powder from accumulating and clogging. At the same time, it vibrates the smaller pre-melted calcium aluminate powder to the bottom of the screening plate 9. When a certain amount of pre-melted calcium aluminate powder particles remain inside, the auger shaft 18 inside the discharge pipe rotates to realize the transfer of the pre-melted calcium aluminate powder particles inside to the outside, thus completing the screening of pre-melted calcium aluminate powder.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
