Anhydrous iron phosphate is an essential raw material for the preparation of lithium iron phosphate.
[0003] Existing equipment for preparing anhydrous ferric phosphate has low heat transfer efficiency and large heat loss, resulting in a large amount of energy consumption required in the preparation of anhydrous ferric phosphate. Utility Model Content
[0004] This utility model discloses a heat source structure and a fluidized crystallization device to solve the technical problem of high energy consumption in the related technology of devices for preparing anhydrous iron phosphate.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] Firstly, a heat source structure is disclosed, including:
[0007] A pipe is a channel that runs through itself along its own axis, and the channel is used to allow gas to pass through;
[0008] Heating components are used to heat pipes;
[0009] The channel is filled with a filling material with gaps, through which gas can be discharged from the outlet of the channel.
[0010] In some designs, the heating assembly includes an insulation layer and several heating elements;
[0011] The insulation layer is wrapped around the outer wall of the pipe;
[0012] Several heating elements are installed on the inner wall of the insulation layer and in contact with the outer wall of the pipe.
[0013] In some designs, the heating element is arranged along the direction of the pipe extension.
[0014] In some designs, there are at least two heating elements; multiple heating elements are spaced apart along the circumference of the pipe.
[0015] In some designs, the spacing between any two adjacent heating elements is equal.
[0016] In some designs, the heating assembly also includes a temperature sensor; the temperature sensor is used to obtain the temperature inside the pipe.
[0017] And / or, the heat source structure also includes a heat insulation layer, which covers the outer peripheral wall of the insulation layer.
[0018] In some designs, the filler is made of non-metallic materials.
[0019] In some designs, the pipeline extends in a straight line from the near end to the far end;

[0037] In the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0038] The inventors discovered during the preparation of anhydrous ferric phosphate that existing devices for preparing anhydrous ferric phosphate have low heat transfer efficiency and large heat loss, resulting in a large amount of energy consumption required in the preparation of anhydrous ferric phosphate.
[0039] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of a heat source structure 100 and a fluidized crystal conversion device 200 through specific embodiments and application scenarios.
[0040] Some embodiments of this application provide a heat source structure 100, such as Figure 3 and Figure 4 As shown, it includes a pipe 110 and a heating assembly 120.
[0041] like Figure 4As shown, pipe 110 has a channel 111 extending along its own axis, through which gas passes. Pipe 110 serves as the main heat exchanger, providing space for heat exchange with the gas. One end of channel 111 is an inlet, and the other end is an outlet. The inlet of channel 111 is used to connect to a gas source 150, such as a fan or air compressor, while the outlet of channel 111 is used to connect to the furnace body 210 for preparing anhydrous ferric phosphate. The gas that has completed heat exchange within channel 111 enters the furnace body 210 through the outlet of channel 111, providing the necessary heat for the preparation of anhydrous ferric phosphate.
[0042] In some embodiments, the conduit 110 extends in a straight line from the proximal end to the distal end. A straight-lined conduit 110 is more efficient in space utilization, occupying less space compared to a curved conduit 110. Furthermore, the straight conduit 110 is easier to manufacture and maintain.
[0043] In some embodiments, the conduit 110 extends in a curved manner from the proximal end to the distal end. Compared to a straight conduit 110, a curved conduit 110 can increase the time that gas spends flowing within the channel 111, thereby improving the heating of the gas.
[0044] like Figure 4 and Figure 5 As shown, the heating component 120 is used to heat the pipe 110. The heating component 120 generates heat and transfers it to the pipe 110, thereby heating the gas flowing in the pipe 110 and the channel 111, so that the gas is heated to the temperature required for the preparation of anhydrous ferric phosphate.
[0045] Specifically, such as Figure 5 As shown, the heating assembly 120 includes an insulation layer 121 and a plurality of heating elements 122. The insulation layer 121 covers the outer peripheral wall of the pipe 110, and the plurality of heating elements 122 are disposed on the inner wall of the insulation layer 121 and are in contact with the outer peripheral wall of the pipe 110.
[0046] The heating element 122 is the main component for generating heat. The heat generated by the heating element 122 is transferred to the pipe 110, thereby heating the gas flowing inside the pipe 110 and the channel 111, raising the gas temperature to the temperature required for the preparation of anhydrous ferric phosphate. Furthermore, the heating element 122 is in contact with the outer wall of the pipe 110, minimizing energy loss during heat conduction. The insulation layer 121 covers the outer wall of the pipe 110, forming a thermal barrier that significantly reduces heat loss. When the heating element 122 heats the pipe 110, the insulation layer 121 ensures that heat is mainly concentrated in and around the pipe 110, rather than rapidly dissipating into the environment, thus improving heating efficiency and allowing the pipe 110 to reach the required temperature in a shorter time. Additionally, the insulation layer 121 provides insulation, preventing injury to operators from direct contact with the heated pipe 110.
[0047] In this embodiment, the heating element 122 can be one, two, three, four, five or more, and can be flexibly set according to actual usage requirements. This embodiment does not limit this.
[0048] In this embodiment, the insulation layer 121 can be made of materials such as ceramic fiber, aluminum silicate fiber, refractory brick, rock wool, and glass wool, and can be flexibly set according to actual usage requirements. This embodiment does not limit this.
[0049] In some embodiments, the heating element 122 is electromagnetically heated. An induction coil is provided on the inner wall of the insulation layer 121, and the induction coil is connected to an AC power source.
[0050] In some embodiments, the heating element 122 is a resistance heater. The inner wall of the insulation layer 121 is provided with a resistive element, and the resistive element is connected to a power source.
[0051] like Figure 4 As shown, the channel 111 is filled with a filler 140, which has gaps, allowing gas to be discharged from the outlet of the channel 111 through the gaps.
[0052] During the flow of gas within channel 111, the presence of filler 140 within channel 111, with gaps in the filler 140, allows gas to flow out through these gaps. However, these gaps also slow down the gas flow rate within the pipe 110, resulting in a longer residence time of the gas within channel 111 for better heat exchange. Secondly, during the heating process of pipe 110 by heating component 120, filler 140 also absorbs heat and rises in temperature. As the gas passes through the gaps in filler 140, heat exchange also occurs between filler 140 and the gas, further enhancing gas temperature. Furthermore, filler 140 increases the heat exchange area with the gas, resulting in more thorough heat exchange.
[0053] In this embodiment, the filler 140 is made of a non-metallic material. By making the filler 140 of a non-metallic material, the gas will not carry metallic impurities into the furnace 210 for preparing anhydrous ferric phosphate during the flow of gas in the channel 111, thus ensuring the high purity and quality of the ferric phosphate.
[0054] In this embodiment, the filler 140 is preferably made of ceramic particles. Ceramic particles maintain structural stability at high temperatures, are not easily deformed or melted, ensuring the integrity and effectiveness of the filler 140 during high-temperature heating. Furthermore, the ceramic particles have moderate thermal conductivity, enabling them to absorb and store heat while also effectively exchanging heat with the gas, thus improving heat exchange efficiency.
[0055] Naturally, in addition to ceramic particles, filler 140 can also be made of other materials, and can be flexibly selected according to actual usage requirements. This embodiment does not limit this.
[0056] like Figure 5 As shown, the heating element 122 is arranged along the extension direction of the pipe 110. By arranging the heating element 122 along the extension direction of the pipe 110, it can be ensured that the gas in the pipe 110 is heated evenly during the flow process, which helps to avoid excessive temperature difference between the front and the end of the pipe 110, thereby improving heating efficiency.
[0057] like Figure 5 As shown, there are at least two heating elements 122; multiple heating elements 122 are arranged at intervals along the circumference of the pipe 110. By arranging multiple heating elements 122 at intervals along the circumference of the pipe 110, it is possible to ensure that the gas is heated more uniformly when flowing in the pipe 110, which helps to reduce the problem of local overheating or uneven cooling, thereby improving heating efficiency.
[0058] like Figure 5As shown, the spacing between any two adjacent heating elements 122 is equal. The arrangement of equally spaced heating elements 122 ensures that the fluid in the pipe 110 is heated more uniformly during flow, and that the gas at different locations in the pipe 110 can obtain a similar heating effect. This is beneficial for the fluid to form a temperature gradient in the pipe 110, thereby improving the uniformity and stability of heating.
[0059] like Figure 2 and Figure 4 As shown, the heating assembly 120 also includes a temperature sensor 123, which can acquire and display the temperature inside the pipe 110, thereby facilitating the operator to determine whether the temperature inside the pipe 110 has reached the temperature required for the preparation of anhydrous ferric phosphate.
[0060] As an optional feature of this embodiment, such as Figure 2 and Figure 4 As shown, the heat source structure 100 also includes a heat insulation layer 130, which covers the outer peripheral wall of the insulation layer 121. The heat insulation layer 130 can effectively prevent heat from being lost outward through the insulation layer 121, further minimizing the energy loss of the heating element 122 during heat conduction and improving heating efficiency. Furthermore, the heat insulation layer 130 also provides some protection for the insulation layer 121, preventing damage and increasing its service life.
[0061] like Figure 4 As shown, there are multiple heating components 120, and the pipe 110 has multiple regions along its axial direction, with one heating component 120 corresponding to each region. By dividing the pipe 110 into multiple regions along its axial direction and setting a separate heating component 120 for each region, more precise heating control can be achieved. This zoned heating method ensures that each region receives an appropriate amount of heat, thereby improving the overall heating efficiency. Furthermore, the zoned control method makes it easier to achieve heating uniformity, thus avoiding localized overheating or undercooling within the pipe 110 and improving heating quality.
[0062] Specifically, each region of the pipe 110 along its own axial direction is covered with an insulation layer 121, and the heating part 122 provided on the inner wall of the insulation layer 121 has the effect of heating the pipe 110.
[0063] In this embodiment, the heating components 120 can be 2, 3, 4 or more, and can be flexibly set according to the length of the pipe 110. This embodiment does not limit this.
[0064] In some embodiments of this application, such as Figure 1 As shown, a fluidized bed crystallization apparatus 200 is also provided, including a furnace body 210 and a heat source structure 100.
[0065] like Figure 1 As shown, the air outlet of channel 111 is detachably connected to the air inlet of furnace body 210. Furnace body 210 is used to prepare anhydrous ferric phosphate, and heat source structure 100 is used to provide the furnace body 210 with the heat required for preparing anhydrous ferric phosphate. Furthermore, the detachable connection between the air outlet of channel 111 and the air inlet of furnace body 210 facilitates the maintenance of furnace body 210 and the feeding of anhydrous ferric phosphate.
