Description

Technical Field

[0001] The utility model relates to the technical field of autoclave cooling systems, and particularly relates to a circulating water cooling structure for a water ring vacuum pump of an autoclave. Background Technique

[0002] An autoclave is a device widely used in the chemical production process, which can carry out chemical reactions and material separation under high temperature and high pressure. When in use, the product is placed in the kettle, the kettle door is closed, and steam is introduced for a series of processes such as steam curing, vulcanization, carbonization, dyeing, cooking, disinfection, etc. The steam introduced during the cooking process continuously heats the product in the kettle. When the product meets the process requirements, the steam in the kettle is released, the kettle door is opened, and the product is taken out. Such containers include hermetically sealed cooking containers such as steam curing and autoclaving kettles for cement products, dye vats, vulcanizing kettles, carbonizing kettles, disinfection tanks, and food cooking kettles.

[0003] When using an autoclave, evacuating is one of the very important operating steps, and the air in the kettle needs to be pumped out to prevent substances such as oxygen from affecting the progress of chemical reactions. Generally, a water ring vacuum pump is used to pump out the air in the kettle. The medium for energy transfer of the water ring vacuum pump is water. The water introduced into the pump body forms a water ring under the action of rotational centrifugal force, and the chamber formed by the water ring and the water pump rotor changes periodically to realize the suction, compression, and discharge of gas. When the gas is discharged, the water is discharged together.

[0004] When evacuating, since the product placed in the kettle has a certain temperature, and the autoclave still maintains a relatively high temperature after the previous use, the air pumped out from the kettle has a high temperature. At the same time, the water ring vacuum pump itself generates heat during operation, so the water discharged from the water ring vacuum pump has a high temperature. Usually, the water introduced into the water ring vacuum pump is only used once and then directly discharged. When recycled, the water temperature rises quickly. After the water temperature rises, the efficiency of the water ring vacuum pump decreases, and it may even stop working, so the water is not reused. Direct discharge causes serious waste of water resources. In addition, the water quality in some areas is relatively hard, causing scale formation and damage to the vacuum pump.

[0005] The utility model mainly solves the deficiencies existing in the prior art, and provides a circulating water cooling structure for a water ring vacuum pump of an autoclave, which has the characteristics of compact structure, good operation stability, good cooling effect, and long service life. The circulating water is quickly cooled down and recycled, reducing water resource waste. After the water is recycled, the calcium in the water does not increase and remains at a relatively low level, solving the problem of scale formation on the vacuum pump.

[0017] Embodiment: As Figure 1As shown in the figure, a circulating water cooling structure for a water ring vacuum pump of an autoclave includes an autoclave 1. A hot water tank 9 is provided on the side of the autoclave 1. A make-up water pipe 11 is provided outside the hot water tank 9, and a filter 10 is provided between the make-up water pipe 11 and the hot water tank 9.

The circulating water is quickly cooled down and recycled, reducing water resource waste. After the water is recycled, the calcium in the water does not increase and remains at a relatively low level, solving the problem of scale formation in the vacuum pump.
