Description

Technical Field

[0001] This utility model belongs to the field of industrial material processing technology, and specifically relates to a cooling mechanism for a mica heating and melting furnace. Background Technology

[0002] Mica is a rock-forming mineral, a general term for layered aluminosilicates composed of potassium, aluminum, magnesium, iron, lithium, etc. Mica is generally polymorphic, with monoclinic crystals being the most common, followed by trigonal crystals, while others are rare. Mica usually occurs in pseudo-hexagonal or rhombic plate, platy, or columnar crystal forms, and its color varies with its chemical composition, mainly becoming darker with increasing Fe content. Its characteristics include insulation and high temperature resistance. The cooling mechanism of the mica heating and melting furnace is a mechanism that helps cool the furnace used for processing mica.

[0003] However, traditional mica heating and melting furnaces have slow heat dissipation when operating at high temperatures, which can easily lead to overheating and aging of the equipment. Passive heat dissipation is inefficient, prolongs the production cycle, and long-term thermal stress accumulation may cause furnace deformation or weld cracking. At the same time, overall thermal expansion can easily cause furnace weld cracking.

[0004] To address the problems mentioned in the background above, a cooling mechanism for a mica heating and melting furnace is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling mechanism for a mica heating and melting furnace, which has the advantages of water cooling and segmented heat dissipation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling mechanism for a mica heating and melting furnace, comprising a furnace body, a sleeve fitted on the surface of the furnace body, a water tank formed on the inner wall of the sleeve, a baffle provided on the left side of the inner wall of the water tank, openings on the top of both sides of the baffle, a second water inlet pipe fitted on the right side of the bottom inside the water tank, a water pump connected to the bottom of the second water inlet pipe, a bottom box embedded outside the water pump, a first water inlet pipe connected to the bottom of the water pump, a water outlet pipe fitted on the left side of the bottom inside the water tank, a water tank fitted inside the bottom box, and the bottoms of the first water inlet pipe and the water outlet pipe penetrating through both sides of the top of the water tank, and a segmented mechanism provided on the top of the sleeve.

[0007] The above technical solution works as follows: After the mica is heated, the water pump draws the coolant from the water tank into inlet pipe one, from inlet pipe one into the water pump, from the water pump into inlet pipe two, and from inlet pipe two into the water tank. The coolant inside the water tank absorbs heat from the furnace surface and enters the outlet pipe through the baffle opening, returning to the water tank. The baffle keeps the water tank full of coolant, increasing the thermal conductivity of the coolant, which then flows out from the opening. After the coolant inside the water tank dissipates heat, it continues to be transported to the water pump to absorb heat, circulating and dissipating heat. After heat dissipation, the water pump is turned off. When the mica needs to be heated, the coolant inside the water tank is returned to the water tank to prevent affecting the heating efficiency. The drainable design enables rapid switching between heating and cooling modes. During heating, the coolant is drained to avoid energy loss, and during cooling, the coolant is injected to form a uniform heat exchange layer. This ensures the heating efficiency of the mica material and reduces the interference of the cooling system on the high-temperature process through physical isolation design. The overall structure is simple, reliable, and has low maintenance costs.

[0008] The present invention is further configured such that the segmented mechanism includes a heat-conducting column, the heat-conducting column is welded to the top of the sleeve, and heat dissipation fins are welded to the top of the heat-conducting column.

[0009] The above technical solution employs a segmented mechanism. The heat from the furnace body is transferred to the heat-conducting column via the sleeve. The segmented design of the heat-conducting column prevents thermal stress concentration and fracture. The heat from the heat-conducting column is transferred to the heat dissipation fins, which help dissipate heat. During the heating process, the overall thermal expansion prevents the furnace body welds from cracking. During the cooling stage, it also helps dissipate heat. The segmented heat conduction and heat dissipation design achieve directional heat conduction, increase the effective heat dissipation area, and significantly improve cooling efficiency. No additional energy consumption is required, and the high-temperature resistance of the metal components ensures long-term stability. This solution is particularly suitable for mica processing processes that require periodic and rapid heat dissipation.

[0010] The present invention is further configured such that a water drain pipe is sleeved at the center of the bottom of the water tank, and the bottom of the surface of the water drain pipe extends through the middle of the top of the water tank, and a water valve is sleeved at the middle of the surface of the water drain pipe.

[0011] The above technical solution involves setting up a drain pipe and a water valve. When mica needs to be heated, the coolant inside the water tank can be drained back into the water tank through the drain pipe, and the water valve can control the flow of coolant out of the drain pipe.

[0012] The present invention is further configured such that fans are embedded in both sides of the bottom box.

[0013] The above technical solution involves installing a fan to dissipate heat from the coolant inside the water tank.

[0014] The present invention is further provided that the fan is fitted with a dust cover.

[0015] The above technical solution employs a dust cover made of detachable metal, which can be installed and removed using bolts, and provides both dust protection and noise reduction.

[0016] The present invention is further configured such that the heat-conducting column is made of graphite.

[0017] The above technical solution is adopted: by using graphite, the high thermal conductivity of graphite can quickly dissipate heat.

[0018] The present invention is further configured such that a water replacement pipe is sleeved on the front of the water tank, and the surface of the water replacement pipe penetrates the front of the bottom box.

[0019] The above technical solution allows for easy replacement of the coolant inside the water tank by installing a water exchange pipe, and the tank is sealed with a cap and valve.

[0020] The present invention is further configured such that a base is bolted to the bottom of the bottom box.

[0021] The above technical solution utilizes a base to stabilize the mechanism.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model achieves rapid switching between heating and cooling modes through a drainable design. During heating, the coolant is drained to avoid energy loss, and during cooling, the coolant is injected to form a uniform heat exchange layer. This not only ensures the heating efficiency of the mica material, but also reduces the interference of the cooling system on high-temperature processes through physical isolation design. The overall structure is simple, reliable and has low maintenance costs.

[0024] 2. This utility model prevents the overall thermal expansion during the heating process from causing cracks in the furnace body welds, aids in heat dissipation during the cooling stage, and achieves directional heat conduction through a segmented heat conduction and heat dissipation design, thereby increasing the effective heat dissipation area and significantly improving cooling efficiency. No additional energy consumption is required, and the high-temperature resistance of the metal components ensures long-term stability. It is particularly suitable for process scenarios in mica processing that require periodic and rapid heat dissipation. Attached Figure Description

A second water inlet pipe 7 is fitted onto the right side of the bottom of the water tank 3, and a water pump 8 is connected to the bottom of the second water inlet pipe 7. The water pump 8 has a flow rate of 5-8L / min and a head of 10-15m, ensuring a coolant flow velocity ≥0.3m / s within the water tank, further improving heat exchange efficiency.

An outlet pipe 11 is fitted onto the left side of the bottom of the water tank 3, and the inside of the base box 9 is fitted with... There is a water tank 10 with a capacity of 80-150L. The bottom of the inlet pipe 6 and the outlet pipe 11 pass through both sides of the top of the water tank 10. The top of the sleeve 2 is equipped with a segmented mechanism. After the mica is heated, the water pump 8 works to draw the coolant inside the water tank 10 into the inlet pipe 6. The coolant enters the water pump 8 from the inlet pipe 6, enters the inlet pipe 7 from the water pump 8, and enters the water tank 3 from the inlet pipe 7. The coolant inside the water tank 3 absorbs the heat from the surface of the furnace body 1 and enters the outlet pipe 11 through the opening 5 of the baffle 4, returning to the water tank 3. The baffle 4 can fill the water tank 3 with coolant, increasing the thermal conductivity of the coolant. The coolant then flows out from the opening 5. After the coolant inside the water tank 3 dissipates heat, it continues to be transported to the water pump 8 to absorb heat and circulate for heat dissipation. After the heat dissipation is completed, the water pump 8 is turned off. When it is necessary to heat the mica, the coolant inside the water tank 3 is returned to the water tank 10 to prevent affecting the heating efficiency.

[0032] refer to Figure 2 , Figure 3A drain pipe 14 is fitted into the center of the bottom of the water tank 3, and the bottom of the drain pipe 14 extends through the middle of the top of the water tank 10. A water valve 15 is fitted into the middle of the drain pipe 14. By setting the drain pipe 14 and the water valve 15, when the mica needs to be heated, the coolant inside the water tank 3 can be drained back into the water tank 10 through the drain pipe 14. The water valve 15 can control the flow of coolant out of the drain pipe 14.

[0033] refer to Figure 1 , Figure 2 Fans 16 are embedded on both sides of the base box 9. By setting up fans 16, the coolant inside the water tank 10 can be cooled, with an airflow of 150-200 m³ / h. 3 / h, with a power of 30-50W, combined with water tank 10 for heat dissipation, so that the coolant cooling rate is ≥5℃ / min.

By setting the water replacement pipe 18, the coolant inside the water tank 10 can be easily replaced, and it is sealed by the cover and valve.

[0036] refer to Figure 1 , Figure 2 The bottom of the base box 9 is bolted with a base 19, which can stabilize the mechanism.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2 A cooling mechanism for a mica heating and melting furnace includes a segmented mechanism comprising a heat-conducting column 12 with a diameter of 10-15mm and a single segment length of 50-80mm. The heat-conducting column 12 is welded to the top of a sleeve 2. Heat dissipation fins 13 are welded to the top of the heat-conducting column 12. The heat dissipation fins 13 have a thickness of 0.8-1.2mm, a spacing of 8-12mm, and are made of 6061 aluminum alloy, thereby increasing the heat dissipation area. The heat conducted by the sleeve 2 to the furnace body 1 is transferred to the heat-conducting column 12. The heat-conducting column 12 is segmented to prevent thermal stress concentration and breakage. The heat from the heat-conducting column 12 is transferred to the heat dissipation fins 13, which help dissipate heat.

[0039] refer to Figure 1 , Figure 2The heat-conducting column 12 is made of graphite. By using graphite, the high thermal conductivity of graphite can quickly conduct heat away. High-purity flake graphite is used, with a purity of ≥99.9% and a thermal conductivity of ≥150W / (m·K).

[0040] Brief description of the usage process: After heating the mica, water pump 8 operates to draw the coolant from inside water tank 10 into inlet pipe 6. The coolant used is deionized water or heat transfer oil with a flash point ≥200℃ to prevent scale formation or high-temperature carbonization. The coolant enters water pump 8 from inlet pipe 6, then from water pump 8 into inlet pipe 7, and finally into water tank 3. The coolant inside water tank 3 absorbs heat from the surface of furnace body 1 and returns to water tank 3 through the opening 5 of baffle 4 into outlet pipe 11. Baffle 4 ensures that water tank 3 is filled with coolant, increasing the coolant level. The heat conduction efficiency is improved, and the coolant flows out from the opening 5. After the coolant inside the water tank 3 dissipates heat, it continues to be transported to the water pump 8 to absorb heat and circulate for heat dissipation. After the heat dissipation is completed, the water pump 8 is turned off. When it is necessary to heat the mica, the coolant inside the water tank 3 is put back into the water tank 10 to prevent it from affecting the heating efficiency. The heat conducted by the furnace body 1 to the sleeve 2 is transferred to the heat conduction column 12. The heat conduction column 12 is set in sections. The section design can prevent thermal stress concentration and breakage. The heat of the heat conduction column 12 is transferred to the heat dissipation fins 13, and the heat dissipation fins 13 help dissipate heat.
