Description

Technical Field

[0001] The utility model relates to the technical field of vacuum casting, in particular to a condensation device for removing vacuum evaporates and a system for removing vacuum evaporates. Background Art

[0002] In the vacuum casting industry, some raw materials are highly volatile and easily volatilize and enter the vacuum pump through the vacuum pipeline, thus sticking to the rotary vane of the vacuum pump, resulting in the failure of the vacuum pump; repairing the vacuum pump and replacing the vacuum pump accessories are costly, greatly increasing the equipment use cost, and the workload during maintenance is large. The existing vacuum pump filtering devices have at least one of the following disadvantages:

[0003] (1) The existing filtering devices cannot effectively filter out vacuum evaporates, and some volatile substances will enter the vacuum pipeline, blocking the vacuum tube and possibly entering the vacuum pump, causing damage to the vacuum pump;

[0004] (2) When the existing filtering devices are maintained, they need to be completely disassembled and cleaned, and the cleaning workload is large. Summary of the Utility Model

[0005] In view of this, the purpose of the present utility model is to provide a condensation device for removing vacuum evaporates and a system for removing vacuum evaporates, which can solve at least one of the technical problems mentioned in the background art. The condensation device proposed in this case can remove vacuum volatiles, effectively protect the vacuum pump, and can be maintained without manual labor for a long time.

[0006] According to one aspect of the present utility model, there is provided a condensation device for removing vacuum evaporates, including a tank body, which is a hollow cavity body, one open end of the cavity is closed by a tank cover, and the other end is used as an air inlet, and an air outlet is arranged on the side wall surface of the cavity; and,

[0007] A heat exchange cavity that fits the outer wall of the cavity is arranged on the outer wall surface of the cavity, and the tank body is filled with stainless steel particles.

[0008] In the above technical solution, the evaporant enters the cavity through the air inlet. At the same time, the temperature inside the cavity is reduced by using the cold and heat exchange cavity, causing the vacuum evaporant to condense from a gas to a solid and deposit on the surface of the stainless steel particles. The evaporant can be effectively removed by this device. The device can switch the evaporant between the gaseous and solid states by increasing the temperature inside the cavity through the cold and heat exchange cavity. The evaporant condenses on the surface of the stainless steel particles to complete the removal work. At the same time, due to the presence of an oxide layer on the stainless steel surface, the surface of the particles has good chemical stability. Under the heating state, the vacuum evaporant returns to the gaseous state, and it is not easy for the evaporant to adhere to the surface of the particles. The evaporant on the surface of the stainless steel particles can be removed by heating to complete the recycling work. Further, stainless steel has good corrosion resistance and can maintain a long service life in harsh environments. For example, it is widely used in fields such as marine, chemical industry, and gas. At the same time, it also has the advantage of being easy to clean, not easily accumulating dirt and bacteria, and can easily maintain hygiene and cleanliness. Therefore, it can be realized that no manual maintenance and cleaning are required for a long time, effectively saving labor.

[0009] In some embodiments, a jacket, a thermal insulation layer, and an armored plate are sequentially arranged on the outer wall surface of the cold and heat exchange cavity.

[0010] In the above technical solution, the purpose of the above setting is to make the thermal insulation material closely fit on the outer surface of the cavity to play a heat preservation role. The presence of the thermal insulation layer keeps the temperature inside the cavity in a stable state, which helps to accurately control the temperature to achieve the evaporation or condensation of the evaporant.

[0011] In some embodiments, a partition A is arranged at the air outlet, and a plurality of air holes are arranged on the partition A; a partition B is arranged at the air inlet, and a plurality of air holes are arranged on the partition B.

[0012] In the above technical solution, the partition A and the partition B are to prevent the stainless steel particles from falling out or being sucked away during evacuation, and can effectively protect the vacuum pipeline and the vacuum pump.

[0013] In some embodiments, an annular heating plate is arranged on the end face of the air inlet.

[0014] In the above technical solution, the purpose of setting the heating plate is to prevent the raw material from condensing at the bottom of the device and causing blockage of the air inlet;

[0015] In some embodiments, the radius of the central ring of the heating plate gradually increases in the air inlet direction.

[0016] In the above technical solution, the purpose of such setting is to facilitate the heated and melted material attached to the core to flow out.

[0017] According to another aspect of the present invention, there is provided a system for removing vacuum evaporates, which consists of at least two sets of the above-mentioned condensation devices.

[0018] In the above technical solution, when the two condensation devices are working, one device is cold and the other is hot, and only one of them is in a vacuum pumping state. The device in the vacuum pumping state is in a cooling state, which can effectively condense the evaporates on the stainless steel particles. The device in the heating state can melt the evaporates condensed on the stainless steel particles and flow back to the raw material tank, which can effectively protect the vacuum pipeline and the vacuum pump. The two devices are used alternately, cold and hot. Through this device, the evaporates can be effectively removed. Moreover, when used alternately in this way, no vacuum evaporates will adhere to the stainless steel particles, and it can be maintained and cleaned without manual labor for a long time, effectively saving labor.
