Potassium sulfate product cooling and conveying device

Abstract

This utility model discloses a potassium sulfate finished product cooling and conveying device, applied in the field of potassium sulfate conveying. It includes a conveying pipe with a conveying mechanism inside and a cooling mechanism on the pipe. The cooling mechanism first fixes a cooling jacket to the conveying pipe, then injects coolant into the cooling jacket through a water inlet pipe. The coolant in the cooling jacket exchanges heat with the potassium sulfate finished product, reducing its temperature and preventing agglomeration. Compared to traditional water-cooling mechanisms, a hollow cavity is opened inside the rotating rod, filled with a low-boiling-point cooling medium. When the cooling medium in the hollow cavity comes into contact with the high-temperature vulcanized product, it vaporizes. The vapor flows axially towards the low-temperature end, liquefies upon cooling, and then flows back through capillary action. The latent heat of phase change quickly removes heat from the shaft core. This dual-cooling composite system improves the cooling efficiency of the potassium sulfate finished product.

Description

Technical Field

[0001] This utility model belongs to the field of potassium sulfate conveying technology, and specifically relates to a potassium sulfate finished product cooling and conveying device. Background Technology

[0002] Potassium sulfate, as an important chlorine-free potassium fertilizer, is widely used in the cultivation of chlorine-sensitive crops such as tobacco and potatoes, as well as in the production of compound fertilizers. In mainstream production processes such as the Mannheim process and the metathesis process, potassium sulfate after high-temperature reaction needs to undergo key processes such as cooling crystallization and separation purification. Traditional cooling and conveying devices play a role in ensuring production continuity.

[0003] The current announcement of Chinese utility model patent CN201721923U discloses a screw conveyor device for potassium sulfate, belonging to the field of potassium sulfate production technology. Its technical features include a conveying pipe and a discharge pipe, wherein the included angle α of the central axis at the connection between the conveying pipe and the discharge pipe is 85°~95°. The conveying device with low conveying resistance and smooth discharge is suitable for conveying potassium sulfate.

[0004] This patent does not include a cooling structure and relies solely on natural heat dissipation. Since potassium sulfate has a high temperature, if it is not cooled during transportation, it is prone to crystallization, forming large lumps. Utility Model Content

[0005] The purpose of this invention is to provide a potassium sulfate finished product cooling and conveying device, which solves the problem of an existing potassium sulfate spiral conveying device that does not have a cooling structure and relies solely on natural heat dissipation. In such cases, the potassium sulfate is at a high temperature and easily crystallizes into large clumps if it is not cooled during conveying.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a potassium sulfate finished product cooling and conveying device, including a conveying pipe, a conveying mechanism is provided inside the conveying pipe, and a cooling mechanism is provided on the conveying pipe; The conveying mechanism includes an inlet, an outlet, a rotating rod, a motor, a reducer, and a spiral plate. The inlet is fixedly located at one end of the conveying pipe, and the outlet is fixedly located at the other end of the conveying pipe. One end of the rotating rod is rotatably located inside the conveying pipe, and the other end of the rotating rod extends to the outside of the conveying pipe. The rotating shaft of the motor is fixedly connected to one end of the rotating rod. The reducer is fixedly located on the rotating shaft of the motor. The spiral plate is fixedly located on the rotating rod and is situated inside the conveying pipe.

[0007] By adopting the above technical solution, and by setting up a conveying pipe, a conveying mechanism, and a cooling mechanism, the potassium sulfate product is first added into the conveying pipe and conveyed, and then cooled by the cooling mechanism to prevent agglomeration. The conveying mechanism includes an inlet, an outlet, a rotating rod, a motor, a reducer, and a spiral plate. In use, the potassium sulfate product is first added into the conveying pipe through the inlet, and then the motor drives the rotating rod to rotate, which in turn causes the spiral plate to rotate, thus conveying the potassium sulfate product in the conveying pipe. Finally, the potassium sulfate product is discharged from the outlet. The reducer can reduce the speed of the motor, allowing the potassium sulfate product to cool for a longer time.

[0008] Furthermore: the cooling mechanism includes a cooling jacket, an inlet pipe, an outlet pipe, a hollow cavity, a sintered metal mesh, and a guide plate. The cooling jacket is fixedly mounted on the conveying pipe and wraps around the conveying pipe. The inlet pipe is fixedly mounted at one end of the cooling jacket, and the outlet pipe is fixedly mounted at the other end of the cooling jacket. The hollow cavity is opened inside the rotating rod and filled with Freon. The sintered metal mesh is mounted on the inner wall of the hollow cavity. A guide plate is fixedly mounted inside the cooling jacket and is spirally arranged.

[0009] The above technical solution, by setting up a cooling jacket, inlet pipe, outlet pipe, hollow cavity, sintered metal mesh, and guide plate, allows for several steps. First, the cooling jacket is fixed to the conveying pipe. Then, coolant is injected into the cooling jacket through the inlet pipe. The guide plate guides the coolant, increasing its flow time within the cooling jacket. A control valve on the outlet pipe facilitates the discharge of coolant from the cooling jacket. The coolant in the cooling jacket exchanges heat with the finished potassium sulfate product, lowering its temperature and preventing agglomeration. Compared to traditional water-cooling mechanisms, a hollow cavity is created inside the rotating rod, filled with a low-boiling-point cooling medium, such as Freon. The sintered metal mesh is a capillary porous material. The cooling medium in the hollow cavity vaporizes upon contact with the finished product in the high-temperature vulcanizing machine. The vapor flows axially towards the low-temperature end, liquefies upon cooling, and then flows back through capillary action. The latent heat of phase change quickly removes heat from the shaft core. This dual-cooling composite system improves the cooling efficiency of the finished potassium sulfate product.

[0010] Furthermore: a fixing block is fixedly installed on the conveying pipe, a grounding plate is installed below the conveying pipe, and a connecting rod is fixedly installed between the grounding plate and the fixing block.

[0011] By adopting the above technical solution, by setting a fixing block, a grounding plate, and a connecting rod, the fixing block is fixedly set on the conveying pipe during use, and then fixed to the grounding plate by the connecting rod, which provides support for the conveying pipe. The grounding plate can increase the contact area with the ground, further improving the stability of the conveying pipe.

[0012] Furthermore: the conveying pipe is hinged with a quick-opening door for clearing blockages, and the number of quick-opening doors for clearing blockages is several and evenly distributed.

[0013] By adopting the above technical solution and setting a quick-opening door for unblocking, when a blockage occurs inside the conveying pipe, the quick-opening door can be opened to unblock the inside of the conveying pipe.

[0014] Furthermore: the spiral plate is provided with tamping fragments, which are right-angled steel sheets, and the tamping fragments are fixedly connected to the spiral plate perpendicularly.

[0015] By adopting the above technical solution, by setting up tamping fragments, the tamping fragments can be driven to rotate when the spiral plate rotates, which can break up the potassium sulfate product and further prevent the potassium sulfate product from clumping.

[0016] Furthermore, a support base is fixedly installed on the ground plane, and the support base provides an installation environment for the motor.

[0017] By adopting the above technical solution and setting up a support base, the support base is fixedly set on the ground plate during use, which can provide an installation environment for the motor.

[0018] Furthermore, the spiral plate is hollow, and its interior is filled with Freon.

[0019] By adopting the above technical solution, Freon is placed inside the spiral plate, and the spiral plate is in close contact with the potassium sulfate product. When the high-temperature potassium sulfate product comes into contact with the spiral plate, the Freon inside the spiral plate can exchange heat with the potassium sulfate product, thereby further improving the cooling efficiency of the potassium sulfate product.

[0020] Furthermore, the connecting rod is fixedly provided with reinforcing ribs, and the number of reinforcing ribs is several and evenly distributed.

[0021] By adopting the above technical solution and setting reinforcing ribs, the load-bearing capacity of the connecting rod can be improved during use, thereby further enhancing the stability of the conveying pipe.

[0022] In summary, this utility model has the following beneficial effects: By setting up a cooling mechanism, during use, the cooling jacket is first fixed to the conveying pipe, and then the coolant is injected into the cooling jacket through the inlet pipe. The coolant is guided by the guide plate to increase the flow time of the coolant in the cooling jacket. Then, a control valve is set on the outlet pipe to facilitate the discharge of the coolant inside the cooling jacket. The coolant in the cooling jacket exchanges heat with the potassium sulfate product, reducing the temperature of the potassium sulfate product and preventing the potassium sulfate product from clumping. Compared with the traditional water cooling mechanism, a hollow cavity is opened inside the rotating rod. The hollow cavity is filled with a low-boiling-point cooling medium, such as Freon. The metal sintered mesh is a capillary porous material. When the cooling medium in the hollow cavity comes into contact with the high-temperature vulcanizing machine product, it vaporizes. The vapor flows axially to the low-temperature end, and after liquefying upon encountering the cold, it flows back through capillary action. The latent heat of phase change is used to quickly remove the heat from the shaft core. The cooling efficiency of the potassium sulfate product is improved through the dual cooling composite system.

[0023] By setting up a conveying mechanism, during use, the potassium sulfate product is first added into the conveying pipe through the feed port. Then, the motor drives the rotating rod to rotate, which in turn rotates the spiral plate, thus conveying the potassium sulfate product in the conveying pipe. Finally, the potassium sulfate product is discharged from the discharge port. The speed reducer can reduce the speed of the motor, allowing the potassium sulfate product to cool down for a longer time.

[0024] Based on the above improvements, the overall technical effect achieved by this device is to cool the potassium sulfate product during transportation, preventing it from caking, and to improve the cooling efficiency of the potassium sulfate product through a dual cooling composite system.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example: Please see Figures 1-4 The present invention provides a technical solution: a potassium sulfate finished product cooling and conveying device, including a conveying pipe 1, a conveying mechanism 2 inside the conveying pipe 1, and a cooling mechanism 3 on the conveying pipe 1; The conveying mechanism 2 includes an inlet 201, an outlet 202, a rotating rod 203, a motor 204, a reducer 205, and a spiral plate 206. The inlet 201 is fixedly installed at one end of the conveying pipe 1, and the outlet 202 is fixedly installed at the other end of the conveying pipe 1. One end of the rotating rod 203 is rotatably installed inside the conveying pipe 1, and the other end of the rotating rod 203 extends to the outside of the conveying pipe 1. The rotating shaft of the motor 204 is fixedly connected to one end of the rotating rod 203. The reducer 205 is fixedly installed on the rotating shaft of the motor 204. The spiral plate 206 is fixedly installed on the rotating rod 203 and is located inside the conveying pipe 1.

[0029] By setting up a conveying pipe 1, a conveying mechanism 2, and a cooling mechanism 3, in use, the potassium sulfate product is first added into the conveying pipe 1 and conveyed, and then cooled by the cooling mechanism 3 to prevent clumping. The conveying mechanism 2 includes an inlet 201, an outlet 202, a rotating rod 203, a motor 204, a reducer 205, and a spiral plate 206. In use, the potassium sulfate product is first added into the conveying pipe 1 through the inlet 201, and then the motor 204 drives the rotating rod 203 to rotate, which in turn causes the spiral plate 206 to rotate, thus conveying the potassium sulfate product in the conveying pipe 1. Then, the potassium sulfate product is discharged from the outlet 202. The reducer 205 can reduce the speed of the motor 204, allowing the potassium sulfate product to cool for a longer time.

[0030] refer to Figure 3 The cooling mechanism 3 includes a cooling jacket 301, an inlet pipe 302, an outlet pipe 303, a hollow cavity 304, a sintered metal mesh 305, and a guide plate 306.

The hollow cavity 304 is opened inside the rotating rod 203 and is filled with Freon. The sintered metal mesh 305 is installed on the inner wall of the hollow cavity 304. The guide plate 306 is fixedly installed inside the cooling jacket 301 and is spirally arranged.

[0031] By configuring a cooling jacket 301, an inlet pipe 302, an outlet pipe 303, a hollow cavity 304, a sintered metal mesh 305, and a guide plate 306, in use, the cooling jacket 301 is first fixed to the delivery pipe 1. Then, coolant is injected into the cooling jacket 301 through the inlet pipe 302. The guide plate 306 guides the coolant, increasing the flow time of the coolant in the cooling jacket 301. A control valve is installed on the outlet pipe 303 to facilitate the discharge of coolant from inside the cooling jacket 301. The cooling effect is achieved through the cooling system within the cooling jacket 301. The liquid exchanges heat with the finished potassium sulfate product to lower its temperature and prevent it from clumping. Compared to traditional water-cooling mechanisms, a hollow cavity 304 is opened inside the rotating rod 203. The hollow cavity 304 is filled with a low-boiling-point cooling medium, such as Freon. The sintered metal mesh 305 is a capillary porous material. When the cooling medium in the hollow cavity 304 comes into contact with the finished product in the high-temperature vulcanizing machine, the vapor flows axially towards the low-temperature end. After liquefying upon cooling, it flows back through capillary action, using the latent heat of phase change to quickly remove the heat from the shaft core. The cooling efficiency of the finished potassium sulfate product is improved through the dual cooling composite system.

By setting the quick-opening door 7, when a blockage occurs inside the conveying pipe 1, the quick-opening door 7 can be opened to clear the blockage inside the conveying pipe 1.

[0034] refer to Figure 4 The spiral plate 206 is provided with tamping fragments 8, which are right-angled steel sheets. The tamping fragments 8 are vertically fixed to the spiral plate 206. By setting the tamping fragments 8, when the spiral plate 206 rotates, it can drive the tamping fragments 8 to rotate, which can break up the potassium sulfate product and further prevent the potassium sulfate product from clumping.

[0038] Brief description of usage: In use, the potassium sulfate product is first added into the conveying pipe 1 through the feed port 201. Then, the motor 204 drives the rotating rod 203 to rotate, which in turn causes the spiral plate 206 to rotate, thus conveying the potassium sulfate product in the conveying pipe 1. Then, the potassium sulfate product is discharged from the discharge port 202. The reducer 205 can reduce the speed of the motor 204, so that the potassium sulfate product has a longer cooling time. Then, the cooling jacket 301 is fixed to the conveying pipe 1, and coolant is injected into the cooling jacket 301 through the water inlet pipe 302. The coolant is guided by the guide plate 306 to increase the flow time of the coolant in the cooling jacket 301. Then, a control valve is installed on the water outlet pipe 303 to facilitate the discharge of coolant from the cooling jacket 301. The coolant in the cooling jacket 301 exchanges heat with the potassium sulfate product to reduce the temperature of the potassium sulfate product and prevent the potassium sulfate product from agglomerating. Compared with the traditional water cooling mechanism, a hollow cavity 304 is opened inside the rotating rod 203, and the hollow cavity 304 is filled with low boiling point... The cooling medium, such as Freon, is a capillary porous material in the sintered metal mesh 305. When the cooling medium in the hollow cavity 304 comes into contact with the finished product in the high-temperature vulcanizing machine, it vaporizes. The vapor flows axially towards the low-temperature end, liquefies upon cooling, and then flows back through capillary action. The latent heat of phase change is used to quickly remove the heat from the shaft core.
