Description

Technical Field

[0001] This utility model relates to the technical field of phosphor bronze brazing filler metal production equipment, and in particular to a flow regulation structure for a phosphor bronze brazing filler metal production crystallizer. Background Technology

[0002] Phosphorus copper brazing filler metal is widely used in the brazing of copper and copper alloys in industries such as refrigeration, motors, and instruments because phosphorus can lower the melting point and improve fluidity. Crystallization equipment directly affects the grain size, phosphorus distribution uniformity, and mechanical properties of the brazing filler metal by precisely controlling the cooling rate and solidification process of the molten alloy. For example, water-cooled crystallizers use circulating water for cooling during the casting stage to avoid phosphorus segregation at grain boundaries and prevent the phenomenon of "phosphorus embrittlement".

[0003] The existing regulating device relies entirely on manual valve operation. Operators need to judge the flow rate based on experience, which is difficult to control precisely. When the temperature or pressure of the molten phosphor bronze fluctuates, the flow rate will change accordingly. Manual adjustment is often lagging and cannot correct deviations in time, resulting in the amount of copper liquid entering the crystallizer fluctuating. This unstable flow rate will cause the liquid level in the crystallizer to fluctuate frequently, which will seriously affect the speed and uniformity of copper liquid cooling and crystallization. It is easy to have local crystallization that is too fast or too slow, which will lead to quality defects such as shrinkage cavities and cracks in the brazing filler metal products.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0020] Reference Figures 1-6This is the first embodiment of the present invention, providing a flow regulation structure for a phosphor bronze solder production crystallizer, including a body 1. A crystallization chamber is formed inside the body 1, with through holes at both axial ends. A feed pipe 2 is fixedly connected to the top of the crystallization chamber, and a regulating pipe 3 is fixedly connected to the top end of the feed pipe 2. A circular column 5 is fixedly connected to the inner ring surface of the regulating pipe 3. A moving groove is formed at the end of the circular column 5 facing the feed pipe 2, and a sliding cylinder 6 is slidably connected within the moving groove. Multiple evenly distributed filter holes 11 are formed on the outer ring surface of the sliding cylinder 6, and a first sealing ring 1 is provided on the inner ring surface of the regulating pipe 3. 3; The sliding cylinder 6 has three designated position areas along its axial direction; when the sliding cylinder 6 is in the first designated area, the first sealing ring 13 is located below the filter hole 11; when the sliding cylinder 6 is in the second designated area, some of the filter holes 11 are located below the first sealing ring 13, and the other part of the filter holes 11 are located above the first sealing ring 13; when the sliding cylinder 6 is in the third designated position area, all the filter holes 11 are located below the first sealing ring 13; A flow sensor 14 is installed on the inner annular surface of the regulating pipe 3, and the flow sensor 14 is located between the sliding cylinder 6 and the feed pipe 2.

[0021] A drive motor 4 is fixedly connected to the outer ring surface of the regulating tube 3. A rotating rod 8 is fixedly connected to the output end of the drive motor 4. The rotating rod 8 passes through the inner wall of the circular column 5. A connecting rod 9 is fixedly connected to the circumferential surface of the rotating rod 8. A hinge 10 is rotatably connected to the inner wall of the connecting rod 9. The bottom end of the hinge 10 is fixedly connected to the top end of the sliding cylinder 6.

[0022] The top of the sliding cylinder 6 is fixedly connected to a number of evenly distributed guide posts 7, and the circular column 5 has a number of evenly distributed guide grooves that slide with the surface of the guide posts 7.

[0023] During use, when the molten phosphor bronze liquid flows in from above the regulating pipe 3, it first contacts the sliding cylinder 6. The filter holes 11 on the surface of the sliding cylinder 6 will intercept the metal impurities in the copper liquid, preventing the impurities from entering the subsequent feed pipe 2 and crystallization chamber. The flow sensor 14, installed on the inner ring surface of the regulating pipe 3 and located between the sliding cylinder 6 and the feed pipe 2, will monitor the flow rate of the copper liquid in real time. When the flow sensor 14 detects that the flow rate deviates from the preset range, it will transmit the signal to the control unit.

[0024] The control unit then starts the drive motor 4. The output of the drive motor 4 drives the rotating rod 8 to rotate, and the connecting rod 9 on the rotating rod 8 rotates accordingly. Through the hinge 10, the sliding cylinder 6 slides in the moving groove of the circular column 5. At the same time, the guide post 7 at the top of the sliding cylinder 6 moves axially along the guide groove in the circular column 5 to ensure the stability of the sliding cylinder 6 during movement. As the sliding cylinder 6 moves, the relative position of its surface and the inner ring surface of the regulating tube 3 changes. When the sliding cylinder 6 slides downward, the surface without filter holes 11 gradually comes into contact with the inner ring surface of the regulating tube 3, the flow area decreases, and the flow rate of the feed pipe 2 decreases accordingly. When the sliding cylinder 6 moves upward, more filter holes 11 are exposed, the flow area increases, and the flow rate increases accordingly, thereby achieving precise regulation of the flow rate of the feed pipe 2. Example 2

[0025] Reference Figures 1-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a plurality of evenly distributed second sealing rings 12 are fixedly connected to the end of the inner ring surface of the circular column 5 facing the feed pipe 2. The inner ring surface of the second sealing ring 12 is in contact with the outer ring surface of the sliding cylinder 6. The inner ring surfaces of the adjusting pipe 3 and the feed pipe 2 are provided with anti-corrosion layers. The surfaces of the circular column 5 and the sliding cylinder 6 are provided with the same anti-corrosion layers.

[0026] A third sealing ring 15 is fixedly connected to the top end of the feed pipe 2. The top end of the third sealing ring 15 is in contact with the bottom end of the regulating pipe 3. A cooling chamber 16 is provided between the crystallization chamber and the outer ring surface of the machine body 1. The cooling chamber 16 has two evenly distributed flow channels. An infrared liquid level sensor 19 is fixedly connected inside the crystallization chamber. The infrared liquid level sensor 19 is close to the bottom end of the feed pipe 2.

[0027] A water inlet pipe 17 is fixedly connected to one end of the flow channel near the feed pipe 2, and a water outlet pipe 18 is fixedly connected to one end of the flow channel near the bottom of the crystallization chamber. A discharge pipe 20 is installed at the bottom of the crystallization chamber.

[0028] During use, the phosphorus copper liquid with regulated flow rate enters the crystallization chamber of the machine body 1 through the feed pipe 2. At this time, the circulating cooling water flows into the cooling chamber 16 from the water inlet pipe 17, flows in the cooling chamber 16 and exchanges heat with the crystallization chamber wall, absorbing the heat of the phosphorus copper liquid, so that the copper liquid gradually cools and solidifies. The cooling water that has completed the heat exchange is discharged from the water outlet pipe 18, forming a continuous cooling cycle. The infrared liquid level sensor 19 installed in the crystallization chamber will monitor the liquid level height of the copper liquid in real time.

[0029] When the infrared liquid level sensor 19 detects that the liquid level is too high or too low, it will send a signal to the control unit. The control unit, in conjunction with the real-time data from the flow sensor 14, will automatically adjust the operation of the drive motor 4 and change the flow rate into the crystallization chamber by adjusting the position of the sliding cylinder 6, so that the liquid level is kept within a suitable range. The whole process does not require manual intervention and realizes the linkage regulation of flow rate and liquid level, ensuring that the copper liquid in the crystallization chamber is cooled and solidified under stable flow rate and liquid level conditions. Finally, the solidified solder is discharged through the discharge pipe 20 at the bottom of the crystallization chamber.

[0030] The remaining structure is the same as that in Example 1.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
