Technical Field
[0001] The utility model relates to the technical field of preheating equipment, in particular to a preheating device for preheating before the mixed reaction of iron phosphate. Background Technique
[0002] Iron phosphate is mainly used in the manufacture of lithium iron phosphate battery materials, catalysts, ceramics, etc. In the preparation process of iron phosphate, a reaction kettle is needed to carry out redox reaction on it. The production process of iron phosphate is as follows: mix iron phosphate, phosphoric acid, and ammonia water, introduce excessive hydrogen peroxide or clean air, and assist with high-temperature steam or heat-conducting oil to increase the reaction temperature. Finally, a more pure iron phosphate precipitate is formed, and the iron phosphate product is obtained through filtration and drying.
[0003] When implementing this technical solution, there are at least the following defects: Although the existing preheating equipment can preheat iron phosphate before the mixed reaction, after the preheating is completed, a large amount of iron phosphate raw materials piled up together will cause blockage, thus affecting the feeding of iron phosphate raw materials. Moreover, the iron phosphate raw materials piled on the surface of the electric heating plate will affect the heat conduction efficiency of other iron phosphate raw materials, and improvement is urgently needed. Therefore, we propose a preheating device for preheating before the mixed reaction of iron phosphate. Content of the Utility Model

A traction rope is wound around the outer side wall of the winding drum. A fixed rod is welded in the middle of the upper end of the support frame.

Also, during the rotation of the arc-shaped frame, the fixed frame on the fixed rod will scrape the surface of the electric heating plate, thereby reducing the influence of the iron phosphate raw material adhering to the surface of the electric heating plate on the heat exchange of other iron phosphate raw materials, and improving the preheating efficiency of the iron phosphate raw material.
[0007] Optionally, the other ends of the two traction ropes are respectively fixedly connected to the upper end of the arc-shaped frame, and the winding directions of the two traction ropes are opposite.
[0008] By adopting the above technical solution, through the arrangement of the traction ropes, the two sides of the arc-shaped frame can be pulled, so that the arc-shaped frame slides on the upper end of the support platform.
[0009] Optionally, an electric heating plate is detachably installed inside the arc-shaped frame, and the electric heating plates are symmetrically arranged.

[0023] Please refer to Figure 1-2, the present utility model provides a technical solution: a preheating device for pre-mixing iron phosphate reaction, including a support platform 1. An arc-shaped frame 11 is arranged at the upper end of the inner cavity of the support platform 1. The lower end of the arc-shaped frame 11 is slidably connected to the upper end of the support platform 1. A material discharging channel 12 is opened on one side of the lower end of the support platform 1. A material discharging port 3 is opened in the middle of the lower end of the arc-shaped frame 11. The arc-shaped frame 11 is designed with the front and rear sides closed and the upper end open. A support frame 2 is welded on the outside of the support platform 1. A servo motor 21 is fixedly installed on one side of the support frame 2. A transmission rod 22 is installed at the output end of the servo motor 21. Winding drums 23 are fixedly installed on both sides of the transmission rod 22. A traction rope 24 is wound around the outer side wall of the winding drum 23. A fixing rod 25 is welded in the middle of the upper end of the support frame 2. A fixing frame 26 is fixedly installed at the lower end of the fixing rod 25. The upper end of the material discharging channel 12 is communicated with the lower end of the material discharging port 3. Through the cooperation of the material discharging channel 12 and the material discharging port 3, the preheated iron phosphate raw material can be discharged. The lower end of the fixing frame 26 is attached to the upper surface of the electric heating plate 13, and the length of the fixing frame 26 is the same as the length of the electric heating plate 13, which is convenient for ensuring the scraping and cleaning effect of the fixing frame 26 on the surface of the electric heating plate 13. The length of the electric heating plate 13 is the same as the width of the arc-shaped frame 11, which is convenient for ensuring the heating effect on the iron phosphate raw material.
[0024] The other ends of the two traction ropes 24 are respectively fixedly connected to the upper end of the arc-shaped frame 11, and the winding directions of the two traction ropes 24 are opposite. Through the arrangement of the traction ropes 24, the two sides of the arc-shaped frame 11 can be pulled, so that the arc-shaped frame 11 slides on the upper end of the support platform 1.
[0025] The electric heating plate 13 is detachably installed inside the arc-shaped frame 11, and the electric heating plates 13 are symmetrically arranged. Through the arrangement of the electric heating plates 13, the iron phosphate raw material inside the arc-shaped frame 11 can be preheated.
[0026] During preheating, first put the iron phosphate raw materials to be preheated into the arc-shaped frame 11, then turn on the electric heating plate 13. The electric heating plate 13 preheats the iron phosphate raw materials in the arc-shaped frame 11. At the same time, turn on the servo motor 21. The servo motor 21 drives the transmission rod 22 to rotate periodically forward and backward. The winding drums on the transmission rod 22 respectively wind or release the traction ropes 24. When the left traction rope 24 is wound, the right traction rope 24 will be released. The left traction rope 24 drives the left side of the arc-shaped frame 11 to slide upward, and vice versa, it will drive the right side of the arc-shaped frame 11 to slide upward. When the right side of the arc-shaped frame 11 slides upward, the discharge port 3 on the arc-shaped frame 11 will coincide with the discharge channel 12, and then discharge the preheated iron phosphate raw materials, thus intermittently discharging the preheated iron phosphate raw materials, avoiding the situation of blockage caused by the discharge of a large amount of preheated iron phosphate raw materials. Moreover, during the rotation of the arc-shaped frame 11, the fixed frame 26 on the fixed rod 25 will scrape the surface of the electric heating plate 13, thereby reducing the influence of the iron phosphate raw materials adhering to the surface of the electric heating plate 13 on the heat exchange of other iron phosphate raw materials, and thus improving the preheating efficiency of the iron phosphate raw materials.
