Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot press furnace technology, specifically to a top cover for a hot press furnace. Background Technology
[0002] The field of autoclave technology focuses on the development and application of specialized equipment capable of processing materials under high temperature and high pressure environments. This equipment is used to manufacture products with high precision, high strength, and special performance requirements. By precisely controlling temperature and pressure conditions, autoclaves can promote the optimization of the internal structure of materials, such as increased density and grain refinement, thereby improving the mechanical and physical properties of the materials.
[0003] The autoclave's lid is a key component, designed to withstand high-temperature and high-pressure environments while ensuring operational safety and airtightness. It is typically made of high-temperature resistant, corrosion-resistant special alloys or ceramic materials, equipped with precision sealing devices to prevent gas leakage, and features necessary interfaces for connecting heating elements, pressure systems, and monitoring equipment such as temperature and pressure sensors. The lid's design also considers ease of operation and maintenance, such as a quick-locking mechanism for easy opening and closing, ensuring stable process conditions and operator safety during processing.
[0004] In the existing technology, the top cover of the autoclave usually does not have an active heat dissipation mechanism. Without effective heat dissipation measures, the temperature of the top cover and its surrounding environment will be too high, which may not only damage the top cover itself, but also cause thermal damage to the surrounding equipment and infrastructure. Utility Model Content
[0005] The purpose of this utility model is to provide a top cover for a hot press furnace to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a top cover for a hot press furnace, comprising a top cover body, a heat dissipation mechanism fixedly installed on the top of the top cover body, a pressure balancing mechanism fixedly installed on the top of the heat dissipation mechanism, the heat dissipation mechanism comprising a water jacket, the water jacket fixedly installed on the top of the top cover body, a heat-conducting sleeve fixedly installed on the top of the water jacket, a first connecting pipe fixedly connected to one side of the heat-conducting sleeve, the first connecting pipe fixedly connected to the top of the water jacket, a second connecting pipe fixedly connected to one side of the heat-conducting sleeve, the second connecting pipe fixedly connected to the top of the water jacket, a circulating pump fixedly installed in the middle section of the second connecting pipe, a plurality of heat dissipation fins fixedly installed on the top of the heat-conducting sleeve, and a cooling fan fixedly installed on the top of the heat dissipation fins.
[0007] Preferably, a pressure relief pipe is fixedly installed at the bottom of the upper cover body, and a pressure relief valve is fixedly installed at the top of the heat dissipation mechanism. The pressure relief pipe passes through the upper cover body and the water jacket and is fixedly connected to the bottom of the pressure relief valve.
[0008] Preferably, a temperature and pressure sensor is fixedly installed at the bottom of the upper cover body.
[0009] Preferably, a second sealing ring is fixedly installed at the bottom of the upper cover body.
[0010] Preferably, the pressure balancing mechanism includes a mounting shell, a third connecting pipe fixedly connected to one side of the mounting shell, the third connecting pipe fixedly connected to the top of the water jacket, two sets of mounting rods fixedly installed inside the mounting shell, pistons slidably mounted on the outer wall of the mounting rods, and springs sleeved on the outer wall of the mounting rods, the springs being located on the side of the pistons away from the third connecting pipes.
[0011] Preferably, a limit rod is fixedly installed on the side of the mounting shell away from the third connecting pipe.
[0012] Preferably, a first sealing ring is fixedly installed on the outer wall of the piston.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the upper cover of the hot press furnace;
[0014] 1. By using a circulating pump, the coolant circulates within the water jacket, the first connecting pipe, the piston, and the heat-conducting jacket. The coolant inside the water jacket carries away the heat from the surface of the upper cover body. Then, through the cooperation between the heat dissipation fins and the heat dissipation fan, the coolant inside the heat-conducting jacket dissipates the heat into the air. In summary, this device has the advantage of actively dissipating heat from the upper cover body, solving the problem in the prior art where the temperature of the upper cover body and its surrounding environment is too high, damaging the upper cover body itself and potentially causing thermal damage to surrounding equipment and infrastructure.
[0015] 2. A spring provides elastic force to the piston towards the third connecting pipe. When the coolant inside the water jacket expands due to heat, and the internal pressure of the water jacket becomes too high, the coolant will overcome the elastic force of the spring and flow into the interior of the mounting shell through the third connecting pipe, where it will be temporarily stored. When the internal pressure of the water jacket returns to normal, the spring and piston will push the coolant inside the mounting shell back into the water jacket. In summary, the pressure balancing mechanism has the function of balancing the internal pressure of the water jacket and preventing the internal pressure of the heat dissipation mechanism from becoming too high due to the expansion of the coolant due to heat.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3 This utility model provides a technical solution: a top cover of a hot press furnace, including a top cover body 1, a heat dissipation mechanism 2 fixedly installed on the top of the top cover body 1, a pressure balancing mechanism 3 fixedly installed on the top of the heat dissipation mechanism 2, the heat dissipation mechanism 2 including a water jacket 201, the water jacket 201 fixedly installed on the top of the top cover body 1, a heat-conducting sleeve 205 fixedly installed on the top of the water jacket 201, a first connecting pipe 202 fixedly connected to one side of the heat-conducting sleeve 205, the first connecting pipe 202 fixedly connected to the top of the water jacket 201, a second connecting pipe 203 fixedly connected to one side of the heat-conducting sleeve 205, the second connecting pipe 203 fixedly connected to the top of the water jacket 201, a circulating pump 204 fixedly installed in the middle section of the second connecting pipe 203, a plurality of heat dissipation fins 206 fixedly installed on the top of the heat-conducting sleeve 205, and a cooling fan 207 fixedly installed on the top of the heat dissipation fins 206.
[0023] A pressure relief pipe 5 is fixedly installed at the bottom of the upper cover body 1, and a pressure relief valve 4 is fixedly installed at the top of the heat dissipation mechanism 2. The pressure relief pipe 5 passes through the upper cover body 1 and the water jacket 201 and is fixedly connected to the bottom of the pressure relief valve 4.
[0024] A temperature and pressure sensor 7 is fixedly installed at the bottom of the main body 1 of the upper cover;
[0025] A second sealing ring 6 is fixedly installed at the bottom of the main body 1 of the upper cover.
[0026] The specific implementation method is as follows: the coolant is circulated inside the water jacket 201, the first connecting pipe 202, the piston 303, and the heat-conducting jacket 205 by the circulating pump 204. The coolant inside the water jacket 201 carries away the heat from the surface of the upper cover body 1. Then, the coolant inside the heat-conducting jacket 205 is cooled by the cooperation between the heat dissipation fins 206 and the heat dissipation fan 207, and the heat is dissipated into the air. In summary, this device has the advantage of actively cooling the upper cover body 1, which solves the problem in the prior art that the temperature of the upper cover body 1 and its surrounding environment is too high, which damages the upper cover body 1 itself and may also cause thermal damage to the surrounding equipment and infrastructure.
[0027] Please see Figure 1-4 This utility model provides a technical solution: a top cover of a hot press furnace, the pressure balancing mechanism 3 includes a mounting shell 301, a third connecting pipe 305 is fixedly connected to one side of the mounting shell 301, the third connecting pipe 305 is fixedly connected to the top of the water jacket 201, two sets of mounting rods 302 are fixedly installed inside the mounting shell 301, a piston 303 is slidably installed on the outer wall of the mounting rod 302, and a spring 304 is sleeved on the outer wall of the mounting rod 302, the spring 304 is located on the side of the piston 303 away from the third connecting pipe 305;
[0028] A limit rod 307 is fixedly installed on the side of the mounting housing 301 away from the third connecting pipe 305;
[0029] A first sealing ring 306 is fixedly installed on the outer wall of piston 303.
[0030] The specific implementation method is as follows: the spring 304 provides the piston 303 with elastic force toward the third connecting pipe 305. When the coolant inside the water jacket 201 expands due to heat, and the internal pressure of the water jacket 201 is too high, the coolant will overcome the elastic force of the spring 304 and flow into the interior of the mounting shell 301 through the third connecting pipe 305, and be temporarily stored inside the mounting shell 301. When the internal pressure of the water jacket 201 returns to normal, the spring 304 and the piston 303 will push the coolant inside the mounting shell 301 back into the water jacket 201. In summary, the pressure balancing mechanism 3 has the function of balancing the internal pressure of the water jacket 201 and preventing the internal pressure of the heat dissipation mechanism 2 from becoming too high due to the expansion of the coolant due to heat.
[0031] Working principle: When using the top cover of the hot press furnace, the circulating pump 204 makes the coolant circulate inside the water jacket 201, the first connecting pipe 202, the piston 303, and the heat-conducting jacket 205. The coolant inside the water jacket 201 carries away the heat from the surface of the top cover body 1. Then, the cooperation between the heat dissipation fins 206 and the heat dissipation fan 207 dissipates the heat from the coolant inside the heat-conducting jacket 205 into the air. In summary, this equipment has the advantage of actively dissipating heat from the top cover body 1, which solves the problem in the prior art that the temperature of the top cover body 1 and its surrounding environment is too high, which damages the top cover body 1 itself and may also cause thermal damage to the surrounding equipment and infrastructure.
[0032] The pressure relief pipe 5 and the pressure relief valve 4 work together to relieve pressure when the pressure inside the hot press is too high. The temperature and pressure inside the hot press are detected by the temperature and pressure sensor 7. The second sealing ring 6 ensures the airtightness between the upper cover body 1 and the hot press.
[0033] Spring 304 provides spring force to piston 303 toward third connecting pipe 305. When the coolant inside water jacket 201 expands due to heat, and the internal pressure of water jacket 201 is too high, the coolant will overcome the spring force of spring 304 and flow into the interior of mounting shell 301 through third connecting pipe 305, and be temporarily stored inside mounting shell 301. When the internal pressure of water jacket 201 returns to normal, spring 304 and piston 303 will push the coolant inside mounting shell 301 back into water jacket 201. In summary, pressure balancing mechanism 3 has the function of balancing the internal pressure of water jacket 201 and preventing the internal pressure of heat dissipation mechanism 2 from being too high due to the expansion of coolant due to heat.
[0034] The maximum displacement distance of the piston 303 is limited by the limiting rod 307, and the sealing between the piston 303 and the mounting shell 301 is ensured by the first sealing ring 306.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
