In agriculture, potassium chloride is a commonly used potassium fertilizer, which plays an important role in the growth and development of crops. In the production process of potassium chloride, it is usually necessary to concentrate the solution so that the concentration of potassium ions reaches the level of crystallization. The preheating dryer can preheat the concentrated solution and increase the temperature of the solution, thereby accelerating the crystallization speed and improving the crystallization efficiency. In order to remove large particles or undissolved solids in the raw materials, screening can be used to remove impurities and evenly transport the raw materials.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a preheating dryer for potassium chloride production, comprising a drying bin 1, a feeding assembly is arranged on the top of the drying bin 1, a motor 2 is fixedly connected inside the drying bin 1, an arc-shaped toothed plate 3 is fixedly connected to the output end of the motor 2, a concave wheel 4 is fixedly connected to the top of the arc-shaped toothed plate 3, a transmission belt 5 is arranged on the outer wall of the concave wheel 4, a double-sided toothed plate 6 is slidably connected inside the drying bin 1, the arc-shaped toothed plate 3 is meshed with the double-sided toothed plate 6, a screening plate 7 is fixedly connected to one end of the double-sided toothed plate 6, a telescopic rod 8 is fixedly connected to one side of the outer wall of the screening plate 7, one end of the telescopic rod 8 is fixedly connected to the inner wall of the drying bin 1, a buffer spring 9 is sleeved on the outer wall of the telescopic rod 8, one end of the buffer spring 9 is fixedly connected to the inner wall of the drying bin 1, the other end of the buffer spring 9 is fixedly connected to the outer wall of the screening plate 7, a guide rail 10 is fixedly connected to the other side of the outer wall of the screening plate 7, and the outer wall of the guide rail 10 is fixedly connected to the inner wall of the drying bin 1;
[0026] Specifically, when the raw material is fed to the top of the screening plate 7, the motor 2 starts to work and drives the arc-shaped tooth plate 3 to rotate through its output end. The design of the arc-shaped tooth plate 3 enables it to effectively mesh with the cam wheel 4. When the arc-shaped tooth plate 3 rotates, the cam wheel 4 will also rotate accordingly, and then the power is transmitted to the arc-shaped tooth plate 3 on the other side through the transmission belt 5, so that it rotates synchronously. In this way, the double-sided tooth plate 6 is driven by the two arc-shaped tooth plates 3 and reciprocates between the two arc-shaped tooth plates 3, which not only ensures the uniform movement of the screening plate 7, but also contributes to the uniform distribution and turnover of the raw materials during the screening process. During the reciprocating movement of the screening plate 7, in cooperation with the buffer spring 9 at the rear, the raw materials above the screening plate 7 can be efficiently screened. The buffer spring 9 provides appropriate elastic force to help the screening plate 7 better adapt to the changes of the raw materials during movement, thereby ensuring the uniformity and consistency of the screening effect. At the same time, in order to ensure that the moving trajectory of the screening plate 7 is accurate, a guide rail 10 is also provided to guide it, ensuring that the screening plate 7 can reciprocate along a predetermined trajectory, which not only realizes the efficient screening of the raw materials, but also ensures the uniform feeding of the raw materials during the drying process.
[0027] Reference Figure 1 , Figure 4 and Figure 5 The feeding assembly includes a feeding plate 22, the bottom of which is fixedly connected to the top of the drying bin 1, a heating pipe 11 is fixedly connected to the inner wall of the drying bin 1, a hot air blower 12 is fixedly connected to the inside of the drying bin 1, a dust collecting plate 13 is fixedly connected to the inside of the drying bin 1, a filter plate 14 is fixedly connected to the inner wall of the dust collecting plate 13, an air duct 15 is fixedly connected to the inner wall of the drying bin 1, a nozzle 16 is fixedly connected to the inside of the air duct 15, a guide plate 17 is fixedly connected to the inner wall of the drying bin 1, a conveying pipe 18 is fixedly connected to the bottom of the guide plate 17, a motor 19 is fixedly connected to the bottom of the drying bin 1, an auger blade 20 is fixedly connected to the output end of the motor 19, and the outer wall of the auger blade 20 is rotatably connected to the inner wall of the conveying pipe 18, and a double door 21 is provided on the outer wall of the drying bin 1;
[0028] Specifically, the raw materials after screening are evenly conveyed to the guide plate 17 below. During this process, the hot air blower 12 continuously inhales external air and heats the air, which not only provides the heat required for drying the raw materials, but also the dust collecting plate 13 and the filter plate 14 filter out dust and impurities, making the air cleaner, thereby ensuring the drying quality of the raw materials. The hot air after dust collection and filtration is guided to the nozzle 16 through the air duct 15. With the action of the heating tube 11, the raw materials are fully dried in the process of falling, and finally guided to the inside of the conveying pipe 18 through the guide plate 17. The motor 19 drives the auger blade 20 to rotate inside the conveying pipe 18, so that the raw materials are continuously and evenly conveyed inside the conveying pipe 18, ensuring the stability and continuity of the raw materials in the subsequent processing process.
[0029] Working principle: when the preheating dryer for potassium chloride production is needed, the raw materials to be dried are first sent to the top of the screening plate 7 through the feed plate 22, and then the arc-shaped toothed plate 3 is driven to rotate through the output end of the motor 2, thereby driving the concave wheel 4 to rotate through the arc-shaped toothed plate 3, and then the arc-shaped toothed plate 3 on the other side is driven to rotate synchronously through the transmission belt 5, thereby driving the double-sided toothed plate 6 to reciprocate between the two arc-shaped toothed plates 3, and then the screening plate 7 is driven to reciprocate through the movement of the double-sided toothed plate 6. This process cooperates with the buffer spring 9 at the rear to screen the raw materials above the screening plate 7, and at the same time The guide rail 10 guides the movement of the screening plate 7 to achieve the effect of screening and uniform feeding. The screened raw materials are evenly transported to the guide plate 17 below. In this process, the external air is heated by the hot air blower 12, and filtered by the dust collecting plate 13 and the filter plate 14. Finally, the raw materials are sprayed out through the air duct 15 and the nozzle 16 to cooperate with the heating tube 11 to dry the raw materials in the process of falling. Then the dried raw materials are sent to the inside of the conveying pipe 18 through the guide plate 17, and then the motor 19 drives the auger blade 20 to rotate inside the conveying pipe 18, so as to continuously and evenly transport the raw materials.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
