Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cooling pushers, in particular to a cooling pusher for conveying potassium sulfate. Background Art
[0002] In the potassium sulfate granule production process, the cooling pusher is a key post-processing device, primarily used for cooling and conveying the material after high-temperature granulation. The cooling pusher uses a screw propulsion mechanism to slowly push the hot potassium sulfate granules (typically 80-120°C) to the discharge end. Simultaneously, a water-cooled jacket provides heat exchange, lowering the granule temperature to 30-50°C, ensuring physical stability and preventing agglomeration.
[0003] The existing cooling pusher gradually exposed its shortcomings during use, mainly in the following aspects:
[0004] First, the pushing distance required for cooling potassium sulfate particles is long, resulting in a long cooling cycle and large limitations on the equipment installation space. Specifically, a water-cooling jacket structure is installed on the outer wall of the pusher shell. When the spiral blades push the potassium sulfate particles in the shell, the potassium sulfate particles are in contact with the shell for cooling. Since the material filling rate is only 30%~50% when the spiral blades are running, the actual contact area between the potassium sulfate particles and the inner wall of the shell is limited, and the effective heat exchange efficiency is low. In order to meet the cooling requirements, the pushing distance of the potassium sulfate material needs to be greatly extended. However, this not only significantly increases the cooling cycle and affects production efficiency, but also increases the limitations of the installation space due to the increase in equipment length, which affects the on-site layout.
[0005] Second, the contact uniformity between the potassium sulfate particles and the shell is poor, resulting in poor cooling effect of the potassium sulfate particles. Specifically, in the process of the spiral blades pushing the potassium sulfate particles to move, the material is in a stable and continuous pushing state in the shell, and the relative movement between the particles is small. Therefore, the contact between the potassium sulfate particles and the inner wall of the shell is uneven, making it difficult to achieve rapid and uniform cooling of the potassium sulfate particles, resulting in poor cooling effect of the potassium sulfate particles.
[0006] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention
[0007] In response to the shortcomings of the prior art, the present invention aims to provide a cooling pusher for conveying potassium sulfate. This device can increase the contact area between the potassium sulfate particles and the inner wall of the shell, significantly improving the effective heat exchange efficiency at the same pushing distance. Thanks to this improvement, the pushing distance required for the device to cool the potassium sulfate particles is significantly shortened, effectively reducing the cooling cycle and also reducing the equipment's installation space requirements.

[0012] As an optimized solution, a stop plate is fixedly provided on the outer wall of the sliding rod, and a compression spring is sleeved on the outer wall of the sliding rod, with both ends of the compression spring correspondingly abutting against the support tube and the stop plate.
[0013] As an optimized solution, the outer wall of the fixed tube is sleeved with a plurality of rotatable rotating sleeves, the inner wall of the rotating sleeve is embedded with a plurality of sealing rings that rub against the outer wall of the fixed tube, the outer wall of the fixed tube located inside the sealing ring is penetrated by an arc-shaped ventilation groove, the outer wall of the rotating sleeve is fixed with a ventilation pipe, one end of the ventilation pipe passes through the rotating sleeve and the sealing ring and is in friction contact with the outer wall of the fixed tube, and the other end of the ventilation pipe passes through the hollow shaft and is connected to the air distribution box.

[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The driving motor drives the hollow shaft and spiral blades to rotate. The spiral blades push the potassium sulfate particles in the shell. The cooling water in the water-cooling jacket exchanges heat with the shell. The pushed potassium sulfate particles contact the inner wall of the shell for cooling. The hollow shaft drives the aggregate box and the spiral plate to rotate when rotating. During the process in which the bottom end of the sliding rod contacts the return area and the base circle area of the cam in succession, the spiral plate continues to insert into the material in the shell, and the material enters the trough of the spiral plate. When the aggregate box is lower than the material height inside the shell, the material in the trough enters the aggregate box. When the aggregate box rotates to the bottom, the filling inside the aggregate box is completed (in this process, the rotating sleeve rotates synchronously with the hollow shaft, but the vent pipe orifice is not connected to the arc vent groove). After that, the hollow shaft continues to rotate. During the process in which the bottom end of the sliding rod contacts the push area of the cam, the vent pipe orifice overlaps with the arc vent groove The pressurized gas in the fixed pipe enters the air distribution box through the vent pipe and is ejected by the injection pipe. The material in the aggregate box is blown into the spiral plate by the pressurized gas and moves along the spiral plate. During the movement of the spiral plate, the material contacts the inner wall of the shell for cooling. At the same time, the sliding rod drives the push plate to slide outward under the push of the cam push area, and then pushes the material in the aggregate box outward, thereby facilitating the blowing out of the material in the aggregate box, and the material blown out from the spiral plate re-enters the interior of the shell. When the sliding rod passes through the cam return area, the push plate slides inward and resets. This equipment can increase the contact area between the potassium sulfate particles and the inner wall of the shell. Under the same pushing distance, the effective heat exchange efficiency is greatly improved. Thanks to this improvement, the pushing distance required for the equipment to cool the potassium sulfate particles is greatly shortened, which not only effectively reduces the cooling cycle, but also reduces the equipment's demand for installation space.
[0022] 2. When the pressurized gas provided by the external gas source passes through the fixed pipe, part of the fixed pipe is cooled because it is in the water-cooling jacket. The low-temperature gas is used to blow the material, further accelerating the cooling speed of the potassium sulfate particles.
[0023] 3. When the hollow shaft rotates, it drives the material plate to rotate, and the material plate turns over the material in the shell. The equipment can turn over the potassium sulfate particles in the process of pushing the potassium sulfate particles, which improves the contact condition between the potassium sulfate particles and the inner wall of the shell, and makes the material constantly and alternately contact with the cooling surface, achieving a faster and more uniform cooling effect on the potassium sulfate particles.

A drive motor 35 is fixedly provided on the top of the support base 1, and a sprocket 33 is fixedly provided on the output end of the drive motor 35 and the outer wall of the hollow shaft 11.

[0046] The water-cooling jacket 6 is fixedly connected to the support base 1 through a plurality of support frames 34 .
[0047] The upper outer wall and the lower outer wall of the shell 3 are respectively fixed with a feed pipe 4 and a discharge pipe 7 which are connected. The upper outer wall and the lower outer wall of the water cooling jacket 6 are respectively fixed with a water outlet pipe 5 and a water inlet pipe 8 which are connected.
[0048] The inner diameter of the nozzle of the air jet pipe 16 is smaller than the particle size of the potassium sulfate particles.
[0049] The working principle of this device is:
[0050] The driving motor 35 drives the hollow shaft 11 and the spiral blade 9 to rotate, and the spiral blade 9 pushes the potassium sulfate particles in the shell 3. The cooling water in the water-cooling jacket 6 exchanges heat with the shell 3, and the pushed potassium sulfate particles contact the inner wall of the shell 3 for cooling. When the hollow shaft 11 rotates, it drives the collection box 14 and the spiral plate 13 to rotate. During the process in which the bottom end of the sliding rod 22 contacts the return area and the base circle area of the cam 27 in succession, the spiral plate 13 continues to insert into the material in the shell 3, and the material enters When the material height of the collecting box 14 is lower than the material height inside the shell 3 in the material trough 12 of the spiral plate 13, the material in the material trough 12 enters the collecting box 14. When the collecting box 14 rotates to the bottom, the filling inside the collecting box 14 is completed (in this process, the rotating sleeve 29 rotates synchronously with the hollow shaft 11, but the vent pipe 25 is not connected to the arc vent groove 28). After that, the hollow shaft 11 continues to rotate. When the bottom end of the sliding rod 22 contacts the push area of the cam 27, the vent pipe 25 is in contact with the arc vent groove 28. The arc-shaped ventilation grooves 28 overlap, and the pressurized gas in the fixed pipe 10 enters the air distribution box 19 through the ventilation pipe 25 and is ejected by the injection pipe 16. The material in the collection box 14 is blown into the spiral plate 13 by the pressurized gas and moves along the spiral plate 13. During the movement of the spiral plate 13, the material contacts the inner wall of the shell 3 for cooling. At the same time, the sliding rod 22 drives the push plate 15 to slide outward under the push of the cam 27 pushing area, thereby pushing the material in the collection box 14 outward, thereby facilitating the material in the collection box 14 to be blown out, and the material blown out from the spiral plate 13 re-enters the interior of the shell 3. When the sliding rod 22 passes the return area of the cam 27, the push plate 15 slides inward and resets. This equipment can increase the contact area between the potassium sulfate particles and the inner wall of the shell 3. Under the same pushing distance, the effective heat exchange efficiency is greatly improved. Thanks to this improvement, the pushing distance required for cooling the potassium sulfate particles by the equipment is greatly shortened, which not only effectively reduces the cooling cycle, but also reduces the installation space requirement of the equipment.
[0051] When the pressurized gas provided by the external gas source passes through the fixed tube 10, a part of the fixed tube 10 is cooled because the part is in the water-cooling jacket 6. The low-temperature gas is used to blow the material, further accelerating the cooling speed of the potassium sulfate particles.
[0052] When the hollow shaft 11 rotates, it drives the material plate 18 to rotate, and the material plate 18 flips the material in the shell 3. The equipment can flip the potassium sulfate particles in the process of pushing the potassium sulfate particles, thereby improving the contact condition between the potassium sulfate particles and the inner wall of the shell 3, so that the material continuously and alternately contacts the cooling surface, thereby achieving a faster and more uniform cooling effect on the potassium sulfate particles.
