Description

Technical Field

[0001] This utility model relates to the field of arc welding flux preparation and sintering equipment processing, and in particular to a sintering equipment for preparing submerged arc welding flux for stainless steel strip. Background Technology

[0002] The sintering device, much like a drying process, removes moisture, water of crystallization, and decomposition products of certain organic substances from the flux mixture. By precisely controlling the sintering temperature, time, and atmosphere, the required slag system can be stably formed. This directly affects the deoxidation, desulfurization, and dephosphorization effects of the weld metal, as well as the transition efficiency of alloying elements. The stable structure of the compounds formed through solid-state reactions ensures that the chemical composition and microstructure of different batches of flux are highly consistent, thereby ensuring the repeatability of welding process performance and weld mechanical properties. However, the existing sintering apparatus for preparing stainless steel submerged arc welding flux still has some problems in practical use: before preparing stainless steel submerged arc welding flux using the sintering apparatus, electrostatic agglomeration will cause powders of different components to form clumps. An ideal sintered flux should have a uniform porous structure, but agglomeration will destroy this structure, forming irregular large pores or dense areas, which will affect the preparation effect of the flux.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A sintering apparatus for preparing submerged arc welding flux for stainless steel with electrodes includes a conical funnel and a primary crushing mechanism. Adjustable crushing mechanisms are provided on both sides of the upper end of the conical funnel. The adjusting crushing mechanism includes a stepper motor, which is fixed to one side edge of the upper end of the conical funnel. The output shaft of the stepper motor is fixedly connected to a rotating rod. One end of the rotating rod is fixedly connected to a limiting slide rod. One end of the limiting slide rod is fixedly connected to an arc-shaped pressure plate. An arc-shaped baffle plate is slidably connected to the inner wall of the arc-shaped pressure plate.

[0005] As a further improvement to this technical solution: the primary crushing mechanism includes an electric push rod, a steel structure support frame is fixedly connected to the bottom of the surface of the electric push rod, a support steel plate is fixedly connected to the upper end of the electric push rod, a limit shaft is slidably connected to the middle of the upper end of the support steel plate through a through hole, a stepper motor is fixedly connected to one side of the lower end of the support steel plate, and a crushing drill bit is fixedly connected to the output shaft of the stepper motor.

[0006] As a further improvement to this technical solution: the lower end of the conical funnel is fixedly connected to a telescopic tube through a through hole, one end of the telescopic tube is fixedly connected to a conical pressure block, and a heating funnel is slidably connected to the surface of the conical pressure block.

[0007] As a further improvement to this technical solution: a connecting component is fixedly connected to one side of the upper end of the heating funnel, and an electric push rod 2 is fixedly connected to one end of the connecting component. One end of the electric push rod 2 is fixedly connected to one side of the upper end of the conical pressure block.

[0008] As a further improvement to this technical solution: a connecting shaft is fixedly connected to one side of the lower end of the heating funnel, and a cover plate is rotatably connected to the surface of the connecting shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By using a conical funnel and an adjustable crushing mechanism, while the crushing mechanism is processing the powder, an arc-shaped baffle slowly approaches the center of the conical funnel in a relative direction to crush the powder. This achieves a finer crushing effect on agglomerated materials, thereby improving the uniformity and fineness of the powder and preventing it from affecting the sintering preparation of the flux.

Detailed Implementation

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0016] Please see Figures 1-6 In this embodiment of the present invention, a sintering device for preparing submerged arc welding flux for stainless steel with electrodes includes a conical funnel 1 and a primary crushing mechanism 2. Adjustable crushing mechanisms 3 are provided on both sides of the upper end of the conical funnel 1. The adjusting crushing mechanism 3 includes a stepper motor 301, which is fixed at one side edge of the upper end of the conical funnel 1. The output shaft of the stepper motor 301 is fixedly connected to a rotating rod 302. One end of the rotating rod 302 is fixedly connected to a limiting slide rod 303. One end of the limiting slide rod 303 is fixedly connected to an arc-shaped pressure plate 304. An arc-shaped baffle plate 305 is slidably connected to the inner wall of the arc-shaped pressure plate 304.

[0017] On both sides of the upper end of the conical funnel 1 near the middle, there are elliptical sliding grooves that are adapted to one end of the rotating rod 302. The design of this elliptical sliding groove provides room for the rotation of the rotating rod 302. When the stepper motor 301 drives the rotating rod 302 to rotate, the limiting slide rod 303 can drive the arc-shaped pressure plate 304 and the arc-shaped baffle plate 305 to adjust the horizontal sliding position, so as to avoid the obliqueness and jamming. An arc-shaped baffle 305 is provided inside the arc-shaped pressure plate 304. When the arc-shaped pressure plates 304 gradually approach each other in opposite directions, the clumps will not flow out from the gap between the two arc-shaped pressure plates 304, thus reducing the crushing effect.

[0018] Please see Figure 1 , 6 The primary crushing mechanism 2 includes an electric push rod 201. A steel structure support frame 4 is fixedly connected to the bottom of the surface of the electric push rod 201. A support steel plate 202 is fixedly connected to the upper end of the electric push rod 201. A limit shaft 203 is slidably connected to the middle of the upper end of the support steel plate 202 through a through hole. A stepper motor 204 is fixedly connected to one side of the lower end of the support steel plate 202. A crushing drill bit 205 is fixedly connected to the output shaft of the stepper motor 204.

[0019] As the electric push rod 201 drives the crushing drill bit 205 and the stepper motor 204 to descend vertically, the limiting shaft 203 vertically limits the support steel plate 202 to prevent the crushing drill bit 205 from shifting laterally due to the reaction force generated during the crushing process, ensuring that it always stays in the central axis position of the conical funnel 1 for precise crushing operations.

[0020] Please see Figures 1-4 The lower end of the conical funnel 1 is fixedly connected to a telescopic tube 5 through a through hole. One end of the telescopic tube 5 is fixedly connected to a conical pressure block 6. A heating funnel 7 is slidably connected to the surface of the conical pressure block 6.

[0021] The conical pressure block 6 is designed to fit the inner wall curvature of the heating funnel 7. When the conical pressure block 6 slides along the inner wall of the heating funnel 7 under the drive of the telescopic tube 5, it can apply uniform extrusion pressure to the initially crushed flux raw material, further refine the particles and remove air from the gaps between the raw materials, so that the raw material forms a compact pre-compression structure before entering the subsequent sintering process, effectively improving the heat transfer efficiency and the density of the finished product during the sintering process.

[0022] Please see Figures 1-2 A connecting component 8 is fixedly connected to one side of the upper end of the heating funnel 7. An electric push rod 9 is fixedly connected to one end of the connecting component 8. One end of the electric push rod 9 is fixedly connected to one side of the upper end of the conical pressure block 6.

[0023] When the electric push rod 29 extends or retracts, the conical pressure block 6 is driven to move inside the heating funnel 7. The conical pressure block 6 presses downward horizontally. During the movement, its outer wall and the inner wall of the heating funnel 7 always remain in close contact. The relative sliding between the two realizes the dynamic extrusion of the flux raw material, so that it is formed into a blank of a specific shape.

[0024] Please see Figure 3 A connecting shaft 10 is fixedly connected to one side of the lower end of the heating funnel 7. A cover plate 11 is rotatably connected to the surface of the connecting shaft 10. A limit bolt 12 is slidably connected to one side of the lower end of the cover plate 11 through a through hole. One end of the limit bolt 12 is threadedly connected to the other side of the lower end of the heating funnel 6.

[0025] Remove the limiting bolt 12 so that the cover plate 11 loses its support and flips on the connecting shaft 10 to open the lower outlet of the heating funnel 7. At this time, the flux blank that has been pre-pressed falls into the receiving funnel 15 under its own gravity and falls into the cooling box 16 to wait for cooling and forming.

[0026] Please see Figures 1-2 A fixed support bracket 13 is fixedly connected to the surface of the heating funnel 7. A support base 14 is fixedly connected to the lower end of the fixed support bracket 13. The upper end of the support base 14 is fixedly connected to the lower end of the steel structure support frame 4 on the side near the back.

[0027] The fixed support 13 provides fixed support for the heating funnel 7 and is connected to the support base 14. The support base 14 is fixedly connected to the steel structure support frame 4, which further improves the structural stability of the entire device and ensures that the heating funnel 7 will not shake or shift during the extrusion molding of flux raw materials and the dropping of the blank, thus providing a reliable support guarantee for the continuous and stable operation of flux preparation.

[0028] Please see Figures 1-2A receiving funnel 15 is fixedly connected to the middle of the upper end of the support base 14 through a through hole. A cooling box 16 is fixedly connected to one end of the receiving funnel 15. A filter screen plate 17 is slidably connected to the inner wall of the cooling box 16. A movable door 18 is rotatably connected to one side of the front of the cooling box 16 through a hinge. The lower end of the cooling box 16 is fixedly connected to the inner bottom wall of the support base 14.

[0029] When the flux blank falls into the cooling box 16, the filter screen 17 filters out the residue on the flux blank, leaving the pure flux blank above the filter screen 17 for subsequent cooling. The cooling box 16 provides a cooling environment for the flux blank through its internal space. The movable door 18 makes it convenient for operators to clean the residue on the filter screen 17 regularly, and also makes it easy to take out the cooled flux blank, which is convenient and practical.

[0030] The working principle of this utility model is as follows: First, the material is placed into the conical funnel 1, and the stepper motor 301 is started to rotate slowly, driving the rotating rod 302 to push the arc-shaped pressure plate 304. When the arc-shaped baffle 305 moves to the preset position with the arc-shaped pressure plate 304, its inner wall and the inner wall of the arc-shaped pressure plate 304 form a continuous arc-shaped extrusion surface, which can crush the blocky material put into the conical funnel 1. At the same time, the arc-shaped baffle 305 can change the extrusion gap by adjusting its sliding position in the arc-shaped pressure plate 304 according to the size of the material agglomeration, so as to adapt to the pretreatment requirements of materials with different particle sizes, effectively improving the adaptability and processing efficiency of the sintering device to raw materials.

[0031] Finally, the powder falls into the heating funnel 7 through the telescopic tube 5. The heating funnel 7 can be adjusted to the preset temperature by an external temperature control device. During the process of the conical pressing block 6 being driven downward by the electric push rod 7, the raw material is preheated simultaneously, so that the internal moisture of the raw material evaporates quickly and is quickly molded. The cover plate 11 is opened to allow the pressed blank to fall freely onto the filter screen plate 17 to remove impurities, and then it waits to cool in the cooling box 16.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
