Description

Technical Field

[0001] This invention relates to the field of precious metal processing equipment technology, and in particular to a material cooling and drying device. Background Technology

[0002] After high-temperature smelting, precious metals require complete cooling before they can be shaped. Conventional cooling methods include air cooling and water cooling. Air cooling is relatively slow, which is not conducive to rapid processing of precious metals. Water cooling is a highly efficient cooling method, but the coolant used in water cooling leaves residue on the surface of the shaped precious metal. Therefore, drying is necessary after water cooling to remove the residual coolant before proceeding to subsequent processes such as testing. In conclusion, designing a device that combines water cooling and drying functions would be extremely beneficial for the automated processing of precious metals. Summary of the Invention

[0003] The purpose of this invention is to provide a material cooling and drying device that addresses the current state of the technology, enabling sequential cooling and drying of materials, with the water cooling system and drying system operating independently. It also allows the cooled material to be automatically centered, facilitating subsequent clamping and lifting.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A material cooling and drying device includes a cooling tank, a telescopic funnel, a telescopic drive mechanism, a water cooling system, and a drying system;

[0006] The cooling tank is a box structure with an open top. A top plate is fixed inside the cooling tank to cover the top opening. The top plate has several water-permeable holes.

[0007] The telescopic funnel includes several funnel cylinders with progressively smaller diameters and equal heights, and a central pin. Each funnel cylinder has an upper flange at its top that extends radially outwards, and a lower flange at its bottom that extends radially inwards. The funnel cylinders are sequentially fitted together, and adjacent funnel cylinders are axially limited by the upper and lower flanges. The central pin is at the same height as the funnel cylinders, and its top has an upper flange that extends radially outwards. The central pin is inserted into the lowest funnel cylinder in the telescopic funnel, and its upper flange and the lower flange of the funnel cylinder are axially limited. The uppermost funnel cylinder in the telescopic funnel passes through and is fixed in the top plate. A bracket is fixedly connected to the lower end of the central pin.

[0008] The telescopic drive mechanism is fixedly installed on the outer wall of the cooling tank, and its output end is fixedly connected to the bracket through a U-shaped bracket.

[0009] The water cooling system is connected to the cooling tank and is used to inject coolant into the cooling tank;

[0010] The drying system is used to dry the material that rises from the telescopic funnel.

[0011] Furthermore, the telescopic drive mechanism includes a drive motor, a ball screw, a bearing housing, and two guide rods. The drive motor and the bearing housing are both fixed on the outer wall of the cooling tank. One end of the ball screw is connected to the output end of the drive motor, and the other end is connected to the bearing housing. One end of the U-shaped bracket is connected to the screw pair on the ball screw, and the other end passes through the top plate and is connected to the bracket. Both guide rods are located in the cooling tank, and their upper ends are fixed on the top plate, while their lower ends are inserted through the bracket.

[0012] Furthermore, the telescopic drive mechanism also includes a telescopic monitor, which includes a first slotted photoelectric sensor, a second slotted photoelectric sensor, and a light-blocking plate. The first slotted photoelectric sensor and the second slotted photoelectric sensor are both fixedly mounted on the outer wall of the cooling tank. The light-blocking plate is fixed to the end of the U-shaped bracket connected to the telescopic drive mechanism, and its position in the vertical direction corresponds to that of the first slotted photoelectric sensor and the second slotted photoelectric sensor.

[0013] Furthermore, each funnel tube has an inclined surface on its inner wall that makes its inner cavity shaped like an inverted frustum, and the inclination of the inclined surface on the inner wall of different funnel tubes is the same.

[0014] Furthermore, the diameters of the various funnel cylinders in the telescopic funnel, from top to bottom, form an arithmetic sequence.

[0015] Furthermore, each funnel cylinder in the telescopic funnel has an opening on its side wall.

[0016] Furthermore, the water cooling system includes an inlet pipe, a water supply pump, an outlet pipe, and a drain pipe. One end of the inlet pipe is connected to the cooling water source, and the other end is connected to the inlet of the water supply pump. One end of the outlet pipe is connected to the outlet of the water supply pump, and the other end extends through the top plate into the cooling tank. One end of the drain pipe is connected to the bottom of the cooling tank, and the other end is connected to the sewage discharge end.

[0017] Furthermore, the drying system includes a blower, a hot air gun, and an air outlet connected in sequence through an air duct, with the air outlet fixed to the top plate by a support.

[0018] Furthermore, it also includes a liquid level monitoring system, which includes a liquid level monitoring tube and a first liquid level sensor and a second liquid level sensor. The liquid level monitoring tube is connected to the cooling tank, and the first liquid level sensor and the second liquid level sensor are connected to the liquid level monitoring tube from bottom to top.

[0019] Furthermore, the lower ends of the two guide rods are fixed by connecting rods.

[0020] The beneficial effects of this invention are as follows:

[0021] Compared to existing technologies, this material cooling and drying device controls the telescopic funnel's shape through a telescopic drive mechanism. When the funnel is extended, it collects material below the liquid level, thus achieving cooling. When the funnel is compressed, the cooled material rises above the liquid level and is centered within the funnel. A robotic arm then grips and lifts the material to the output of the drying system for drying. This material cooling and drying device can sequentially cool and dry materials without interference between the water cooling and drying systems. It also automatically centers the cooled material, facilitating subsequent gripping and lifting. Attached Figure Description

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] Please see Figure 1-6 As shown, a material cooling and drying device includes a cooling tank 1, a telescopic funnel 11, a telescopic drive mechanism, a water cooling system, and a drying system.

[0031] The cooling tank 1 is a box structure with an open top. A top plate 12 is fixed inside the cooling tank 1 to cover the top opening. The top plate 12 has several water-permeable holes.

[0032] The telescopic funnel 11 includes several funnel cylinders 25 with progressively smaller diameters and equal heights, and a central pin 26. Both the funnel cylinders 25 and the central pin 26 are made of metal.

[0033] Each funnel 25 has an upper flange at its top that extends radially outward, and a lower flange at its bottom that extends radially inward. The funnels 25 are sequentially fitted together, and adjacent funnels 25 are axially limited by the upper and lower flanges.

[0034] The center pin 26 is at the same height as the funnel cylinder 25, and its top is provided with an upper flange that extends radially outward. The center pin 26 is inserted into the lowermost funnel cylinder 25 of the telescopic funnel 11, and its upper flange and the lower flange of the funnel cylinder 25 form a limit in the axial direction.

[0035] The uppermost funnel cylinder 25 of the telescopic funnel 11 passes through and is fixed in the top plate 12, and a bracket 19 is fixedly connected to the lower end of the central pin 26.

[0036] Among them: each funnel cylinder 25 has an inclined surface on its inner wall that makes its inner cavity into an inverted frustum shape, and the inclination of the inclined surface on the inner wall of different funnel cylinders 25 is the same; the diameters of each funnel cylinder 25 in the telescopic funnel 11 from top to bottom are in an arithmetic sequence.

[0037] According to the above design, the inner cavity of the telescopic funnel 11 can be made to approximate a cone, which is closer to the shape of a funnel.

[0038] The telescopic drive mechanism is fixedly installed on the outer wall of the cooling tank 1, and its output end is fixedly connected to the bracket 19 through the U-shaped bracket 18.

[0039] In the above technical solution, the telescopic drive mechanism is used to drive the bracket 19 to push the central pin 26 and each funnel cylinder 25 in the telescopic funnel 11 upward in sequence, so that they overlap.

[0040] Specifically, the telescopic drive mechanism includes a drive motor 14, a ball screw 15, a bearing housing 16, and two guide rods 20. The drive motor 14 and the bearing housing 16 are both fixed on the outer wall of the cooling tank 1. One end of the ball screw 15 is connected to the output end of the drive motor 14, and the other end is connected to the bearing housing 16. One end of the U-shaped bracket 18 is connected to the screw pair on the ball screw 15 (through the bracket 17), and the other end passes through the top plate 12 and is connected to the bracket 19. Both guide rods 20 are located in the cooling tank 1, and their upper ends are fixed on the top plate 12, while their lower ends are inserted through the bracket 19.

[0041] Preferably, the lower ends of the two guide rods 20 are fixed by a connecting rod 21 to reinforce the relative position of the two guide rods 20 and facilitate guidance.

[0042] The water cooling system is connected to cooling tank 1 and is used to inject coolant into cooling tank 1. Generally, the coolant is water.

[0043] Specifically, the water cooling system includes an inlet pipe 3, a water supply pump 2, an outlet pipe 4, and a drain pipe 5. One end of the inlet pipe 3 is connected to the cooling water source, and the other end is connected to the inlet of the water supply pump 2. One end of the outlet pipe 4 is connected to the outlet of the water supply pump 2, and the other end passes through the top plate 12 and extends into the cooling tank 1. One end of the drain pipe 5 is connected to the bottom of the cooling tank 1, and the other end is connected to the sewage outlet. Generally, the sewage outlet is a sewer.

[0044] It also includes a liquid level monitoring system, which includes a liquid level monitoring tube 8 and a first liquid level sensor and a second liquid level sensor. The liquid level monitoring tube 8 is connected to the cooling tank 1 to form a communicating vessel. The first liquid level sensor and the second liquid level sensor are connected to the liquid level monitoring tube 8 from bottom to top.

[0045] Automatic liquid replenishment occurs when the second liquid level sensor does not detect a liquid level, and liquid replenishment stops when the first liquid level sensor detects a liquid level.

[0046] It should be noted that the coolant level should not exceed 12 mm above the top plate.

[0047] Among them, each funnel cylinder 25 in the telescopic funnel 11 has an opening 25-1 on its side wall.

[0048] According to the above design, when the telescopic drive mechanism drives the bracket 19 to push the center pin 26 and each funnel cylinder 25 in the telescopic funnel 11 upward in sequence and make them overlap, the coolant in the telescopic funnel 11 will be discharged faster through the opening 25-1.

[0049] The drying system is used to dry the material that rises from the telescopic funnel 11.

[0050] Specifically, the drying system includes a blower 6, a hot air gun 7, and an air outlet 9 connected in sequence through an air duct. The air outlet 9 is fixed to the top plate 12 by a support 10.

[0051] In one embodiment, the telescopic drive mechanism also includes a telescopic monitor, which includes a first slotted photoelectric sensor 22, a second slotted photoelectric sensor 23, and a light-blocking plate 24. The first slotted photoelectric sensor 22 and the second slotted photoelectric sensor 23 are both fixedly mounted on the outer wall of the cooling tank 1. The light-blocking plate 24 is fixed to the end of the U-shaped bracket 18 connected to the telescopic drive mechanism, and its position in the vertical direction corresponds to that of the first slotted photoelectric sensor 22 and the second slotted photoelectric sensor 23.

[0052] In the above technical solution, the state of the telescopic funnel 11 is monitored by the first slotted photoelectric sensor 22, the second slotted photoelectric sensor 23, and the light-blocking plate 24. Specifically, when the first slotted photoelectric sensor 22 detects the light-blocking plate 24, the bracket 19 is in its highest position, and the telescopic funnel 11 is in a compressed state; when the second slotted photoelectric sensor 23 detects the light-blocking plate 24, the bracket 19 is in its lowest position, and the telescopic funnel 11 is in an extended state.

[0053] In order to better assemble the telescopic drive mechanism on the cooling tank 1, an mounting plate 13 is fixedly installed on the outer wall of the cooling tank 1. The drive motor 14, bearing seat 16, first slot-shaped photoelectric sensor 22, and second slot-shaped photoelectric sensor 23 are all mounted on the mounting plate 13.

[0054] In summary, this invention controls the telescopic funnel 11 to change its shape via a telescopic drive mechanism. When the telescopic funnel 11 is in the extended state, it is used to collect material, which is below the liquid level, thus achieving cooling. When the telescopic funnel 11 changes to the compressed state, the cooled material rises above the liquid level and is positioned at the center of the telescopic funnel 11. Then, a matching robotic arm (not shown in the figure) clamps and lifts the material to the output end of the drying system for drying. The above-mentioned material cooling and drying device can sequentially cool and dry materials, and the water cooling system and the drying system do not interfere with each other. At the same time, it can automatically center the cooled material, which is beneficial for subsequent clamping and lifting.

[0055] Of course, the above are only preferred embodiments of the present invention and are not intended to limit the scope of application of the present invention. Therefore, any equivalent changes made to the principle of the present invention should be included within the protection scope of the present invention.
