Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange in vacuum furnaces, and particularly to a heat exchange device for a vacuum furnace. Background Art

[0002] A vacuum furnace is a device that uses a vacuum system within a specific space of a furnace chamber, which is carefully assembled from components such as vacuum pumps, vacuum measurement devices, and vacuum valves. It evacuates some substances within the furnace chamber to make the pressure within the furnace chamber less than one standard atmospheric pressure, thereby achieving a vacuum state in the furnace chamber space. This is a vacuum furnace. Among them, vacuum quenching, including tempering and annealing processes, is to heat and cool materials or parts under vacuum conditions according to process specifications to achieve the desired performance. The working principle of a vacuum furnace is to create a low-pressure environment with almost no air by pumping out the vacuum, and then utilize the principle that water boils at a low temperature to generate steam under a pressure lower than atmospheric pressure and output heat through the heat exchange of steam condensation.

[0003] The existing cooling method of the heat exchange device for a vacuum furnace is relatively single. Generally, by increasing the length of the intake pipe, the residence time of the gas in the pipe is increased to achieve the purpose of cooling. However, in this way, the internal gas temperature during the heat exchange process is not cooled evenly enough, and it cannot ensure that the gas is completely cooled, often failing to meet specific requirements and being difficult to meet people's expectations for products. Moreover, the longer intake pipe occupies a relatively large space, resulting in a gradual increase in volume and cost, affecting the stability and safety of the vacuum system.

[0010] Preferably, the core part is slidably connected with a vertical block through a torsion spring, and a rod fitting adapted to the torsion spring is arranged at the center of the inner cavity of the vertical block. There are four groups of wiping sliders, six in each group. The torsion spring drives the core part to move, and the core part acts on the wiping sliders to move synchronously.

The water vapor inside the uniform block is introduced into the heat conduction part, and through the cooperation of the heat conduction part, the air outlet connection chamber and the vacuum system, the heat output by the exchange is output.

[0013] (III) Beneficial effects The present invention provides a heat exchange device for a vacuum furnace. It has the following beneficial effects: (I). For this heat exchange device for a vacuum furnace, the vacuum inside the device is pumped out through the air outlet connection chamber, and water is introduced by using a water cooling device. Water enters the output main part, and the flange backing plate helps the output main part to be more stable. The water passes through the uniform block and the air inlet pipe, enabling the device to have the effect and function of heat exchange and providing a certain basis for heat exchange.

[0014] (2) The heat exchange device for the vacuum furnace is such that part of the water passes through the uniform block. The side of the uniform block is provided with uniformly different dispersion holes. The water inside the uniform block is gradually dispersed into individual thin streams and continuously moves to the right. The cold air generated by the inflow of water gradually moves upward. Another part enters the intake pipe and the heat-conducting part. The intake pipe is in a curved shape, which greatly increases the residence time of the gas in the water in the pipe. The water vapor inside the uniform block is transmitted into the heat-conducting part, and through the cooperation of the heat-conducting part with the air outlet bin and the vacuum system, the exchanged heat is output, thereby accelerating the cooling speed of the internal gas temperature. The water cooling is relatively uniform, achieving the effect of ensuring complete cooling of the gas. (3) The heat exchange device for the vacuum furnace is such that when the water moves, a certain flow velocity force is generated. The water impacts the balance pendulum inserted into the inner cavity of the output main part. The balance pendulum is forced to shake. The shaking of the balance pendulum causes a certain jolt of the metal round shaft. The track at the bottom of the jolting metal round shaft rotates along the rotating groove in the inner cavity of the balance pendulum. The rotation of the metal round shaft drives the swinging vane to swing. The swinging of the swinging vane quickly pushes the wind back, improving the efficiency of water uniformity and heat exchange, and achieving the purpose of saving time.

[0015] (4) The heat exchange device for the vacuum furnace is such that the wiping block also swings accordingly. The wiping block gradually symmetrically adjusts the balance performance of the device, avoiding the situation of one end being too high or too low, and achieving the processing effect of synchronous balanced operation.

[0016] (5) The heat exchange device for the vacuum furnace is such that when the device leaks water or air, part of the gas or water body is affected by gravity and penetrates the output main part, and falls to the bottom of the output main part. The water inside the output main part squeezes the sensitive lifting plate. The sensitive lifting plate bounces and the strong spring moves. The strong spring is gradually compressed and stores energy. As the water increases, it gradually pushes the upper guide plate, so that the rubber repair part at the top of the guide plate covers the outer wall of the output main part. At the same time, the center of the cleaning device is also coated with a waterproof film with strong sealing performance, so as to play the role of automatic leakage maintenance and have the effect of automatic protection.

[0017] (6) The heat exchange device for the vacuum furnace is such that when the balance pendulum shakes, it will also swing the opposing block at the same time. The rod fitting inside the opposing block is squeezed by the balance pendulum. The rod fitting extends and pushes the torsion spring. The torsion spring extends and twists. The torsion spring drives the core part to move. The core part acts on the wiping slider to move synchronously, thus realizing the function and effect of automatically cleaning the inner wall of the device and improving the practical performance of the device.

[0028] The inner cavity of the uniform block 34 is provided with a hole adapted to the intake pipe 35, and the intake pipe 35 is in a curved shape. The central holes evenly distributed are arranged on the right end plane of the uniform block 34. The balance ornament 36 and the wiping block 39 are perpendicular to each other.

The cold air generated by the inflow of moisture gradually operates upward, and the specifications and dimensions of the balance ornament 36 and the wiping block 39 correspond to each other.

[0029] During use, first check the installation, fixation and safety protection of the present invention. The vacuum inside the device is pumped out through the air outlet connection chamber 4, and water is introduced into the water cooling device 3. The moisture enters the output main part 32.

At the same time, a waterproof film with strong sealing performance is also coated at the center of the cleaning device 61, so that it can play the role of automatic water leakage maintenance and has the effect of automatic protection. When the balance ornament 36 shakes, it will swing the upright block 611 at the same time. The rod fitting inside the upright block 611 is squeezed by the balance ornament 36, and the rod fitting extends to push the torsion spring 612. The torsion spring 612 stretches and twists, and the torsion spring 612 drives the core part 613 to move.
