Description

Technical Field

[0001] This utility model belongs to the field of high-purity phosphorus pentasulfide preparation technology, specifically relating to a high-purity phosphorus pentasulfide preparation device. Background Technology

[0002] The design and construction of a high-purity phosphorus pentasulfide (P2S5) preparation device involves multiple components and steps. The following is an overview as well as common equipment configurations and operating points: It is necessary to prepare raw materials of pure phosphorus (usually red phosphorus or black phosphorus) and high-purity sulfur. These raw materials need to be pretreated to remove impurities. A reaction vessel and a heating device are also required. Generally, the reaction vessel is made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel or special alloys. The reaction conditions are usually carried out at 300-500℃ to accelerate the reaction between phosphorus and sulfur.

[0003] The existing high-purity phosphorus pentasulfide preparation equipment has the following disadvantages during use:

[0004] In the preparation of high-purity phosphorus pentasulfide, pure phosphorus and high-purity sulfur are required to be fed into the reaction device separately in a one-time ratio. This can easily lead to violent reactions during stirring, posing a safety hazard. There is a lack of a structure that allows for the separate and intermittent feeding of the two raw materials into the reaction device. Furthermore, the pure phosphorus and high-purity sulfur added to the feeding hopper are prone to blockage during feeding, greatly reducing the feeding efficiency. Therefore, a high-purity phosphorus pentasulfide preparation device is needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-purity phosphorus pentasulfide preparation apparatus to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-purity phosphorus pentasulfide preparation device, comprising a preparation tank, an electric heating plate fixedly connected to the inner bottom wall of the preparation tank, two symmetrically arranged C-shaped supports fixedly connected to the outer top of the preparation tank, a feed pipe fixedly connected to one end of each of the two C-shaped supports facing each other, a feeding hopper fixedly connected to the top of each feed pipe, a motor fixedly connected between the two feeding hoppers through a support plate, a stirring shaft fixedly connected to the output shaft of the motor, an intermittent feeding structure installed between the stirring shaft and the top of the preparation tank, the bottom end of the stirring shaft extending into the preparation tank and fixedly connected to multiple stirring blades, and a discharge pipe with a solenoid valve provided at the center of the bottom end of the preparation tank;

[0007] It also includes a linked striking structure, which is mounted on the two C-shaped brackets and connected to the intermittent feeding structure.

[0008] In a preferred embodiment, the intermittent feeding structure includes a circular rotating groove at the top of the preparation tank. The vertical cross-section of the circular rotating groove is I-shaped. A rotating disk with an I-shaped vertical cross-section is rotatably connected in the circular rotating groove. The rotating disk is fixed to the outside of the stirring shaft.

[0009] In a preferred embodiment, the rotating disk has two symmetrically arranged feeding ports, the diameter of which is smaller than the diameter of the bottom opening of the feed pipe.

[0010] In a preferred embodiment, the linkage striking structure includes a sliding groove at the top of each of the two C-shaped supports, in which a slider with an I-shaped vertical cross-section is slidably connected. A connecting block is fixed to the top of each slider, and a striking ball is fixed to the top of each of the two connecting blocks.

[0011] In a preferred embodiment, the bottom ends of both sliders are fixedly connected to a transmission column, the opposite ends of the two sliders are connected to the inner wall of the slide groove by a spring, and the outer sides of the transmission columns are movably connected to the outer side of the transmission plate.

[0012] In a preferred embodiment, the cross-section of each transmission plate is a right-angled trapezoidal structure, and the opposite ends of the two transmission plates are fixed to the outer side of the rotating disk.

[0013] Compared with the prior art, the high-purity phosphorus pentasulfide preparation apparatus provided by this utility model has at least the following beneficial effects:

[0014] In this invention, when using the high-purity phosphorus pentasulfide preparation device, the proportioned raw materials, pure phosphorus and high-purity sulfur, can be placed in their respective feeding hoppers. By starting the motor, the stirring shaft drives the rotating disk to rotate clockwise, while multiple stirring blades rotate. Simultaneously, when the two feeding ports coincide with the bottom openings of the corresponding feed pipes, the pure phosphorus and high-purity sulfur raw materials fall into the preparation tank. With the electric heating plate energized, the pure phosphorus and high-purity sulfur raw materials can be stirred and heated to react, achieving intermittent feeding of pure phosphorus and high-purity sulfur raw materials. This effectively prevents the problem of violent reactions and safety hazards caused by a single feeding and stirring reaction. In addition, the inclined surface on the transmission plate presses against the transmission column, causing the slider to compress the spring. After the transmission plate leaves, the spring's rebound force causes the slider to drive the striking ball connected to the connecting block to strike the outside of the feeding hopper, achieving a striking effect during intermittent feeding and effectively preventing blockage during feeding.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Example

[0023] In the preparation of high-purity phosphorus pentasulfide, the raw materials of pure phosphorus and high-purity sulfur need to be fed into the reaction device in a one-time ratio. This makes it easy for violent reactions to occur during stirring, which can easily lead to safety hazards. There is a lack of a structure that can feed the two raw materials into the reaction device separately and intermittently. Secondly, the raw materials of pure phosphorus and high-purity sulfur added to the feeding hopper 22 are prone to blockage during feeding, which greatly reduces the feeding efficiency.

[0024] For this purpose, please refer to Figure 1-3 This utility model provides a high-purity phosphorus pentasulfide preparation apparatus, comprising: a preparation tank 1, wherein an electric heating plate 11 is fixedly connected to the inner bottom wall of the preparation tank 1, the electric heating plate 11 has a circular cross-section and a through hole in the middle, and is attached with... Figure 2As can be seen, two symmetrically arranged C-shaped supports 2 are fixed to the outer top of the preparation tank 1. Each of the two C-shaped supports 2 has a feed pipe 21 fixed to one end facing each other. The top of each feed pipe 21 is fixedly connected to a feeding hopper 22. A motor 3 is fixed between the two feeding hoppers 22 through a support plate. A stirring shaft 31 is fixed to the output shaft of the motor 3. An intermittent feeding structure 5 is installed between the stirring shaft 31 and the top of the preparation tank 1. The bottom end of the stirring shaft 31 extends into the preparation tank 1 and is fixed with multiple stirring blades 32. A discharge pipe 4 with a solenoid valve is provided at the center of the bottom end of the preparation tank 1.

[0025] It also includes a linkage striking structure 6, which is mounted on two C-shaped brackets 2 and connected to the intermittent feeding structure 5.

[0026] Further as Figure 1-3 As shown, it is worth noting that the intermittent feeding structure 5 includes a circular rotating groove at the top of the preparation tank 1. The vertical cross-section of the circular rotating groove is I-shaped. A rotating disk 51 with an I-shaped vertical cross-section is rotatably connected in the circular rotating groove. The rotating disk 51 is fixed to the outside of the stirring shaft 31. Two symmetrically arranged feeding ports 52 are opened on the rotating disk 51. The diameter of the feeding port 52 is smaller than the diameter of the bottom opening of the feed pipe 21.

[0027] Further as Figure 1-3 As shown, it is worth noting that in order to simultaneously achieve the knocking of the outer sides of the two feeding hoppers 22 while the intermittent feeding structure 5 is in operation, a linkage knocking structure 6 is provided. This structure includes a chute at the top of each of the two C-shaped supports 2. A slider 61 with an I-shaped vertical cross-section is slidably connected in the chute. A connecting block 62 is fixed to the top of each slider 61. A knocking ball 63 is fixed to the top of each of the two connecting blocks 62. A transmission column 65 is fixed to the bottom of each slider 61. The opposite ends of the two sliders 61 are connected to the inner wall of the chute through a spring 64. The outer sides of the transmission columns 65 are movably overlapped with the outer sides of the transmission plates 66. The cross-section of each transmission plate 66 is a right-angled trapezoidal structure. The opposite ends of the two transmission plates 66 are fixed to the outer sides of the rotating disk 51.

[0028] Appendix Figure 3 The spring 64 is compressed by the slider 61. When the transmission plate 66 leaves, the rebound force of the slider 61 will cause the slider 61 to drive the striking ball 63 connected to the connecting block 62 to strike the outside of the feeding hopper 22.

[0029] In summary: When using this high-purity phosphorus pentasulfide preparation device, the proportioned raw materials, pure phosphorus and high-purity sulfur, can be poured into their respective feeding hoppers 22. By starting the motor 3, the stirring shaft 31 drives the rotating disk 51 to rotate clockwise, while multiple stirring blades 32 rotate. Simultaneously, when the two feeding ports 52 align with the bottom openings of their respective feed pipes 21, the pure phosphorus and high-purity sulfur raw materials fall into the preparation tank 1. With the electric heating plate 11 energized, the pure phosphorus and high-purity sulfur... The raw materials are stirred and heated to react, and the intermittent feeding of pure phosphorus and high-purity sulfur raw materials is achieved, which effectively prevents the problem of violent reaction and safety hazards caused by one-time feeding and stirring reaction. In addition, the inclined surface on the transmission plate 66 will press against the transmission column 65 to drive the slider 61 to compress the spring 64. After the transmission plate 66 leaves, the spring 64 will rebound, causing the slider 61 to drive the striking ball 63 connected to the connecting block 62 to strike the outside of the feeding hopper 22, realizing the striking during intermittent feeding and effectively preventing the phenomenon of blockage during feeding.
