Description

technical field [0001] The invention relates to a rotary vane vacuum pump suitable for brick and tile vacuum extruders, belonging to the technical field of vacuum pumps, suitable for vacuuming equipment in building materials, chemical industry, medicine, electronics, ceramics and other industries, especially suitable for use in brick and tile vacuum extruders. Rotary vane vacuum pumps used in tile vacuum extruders. Background technique [0002] Vacuum extruder is a production machine widely used in brick and tile manufacturing industry at present, and vacuum pump is the most important supporting equipment in vacuum extruder. Conventional water ring vacuum pumps, slide valve vacuum pumps or rotary vane vacuum pumps are usually used in traditional vacuum extruders, but the following technical problems generally exist in actual use: 1) The use of water ring vacuum pumps has low working vacuum, The problem of low pumping efficiency and high energy consumption; 2) When using a c...

Problems solved by technology

Conventional water ring vacuum pumps, slide valve vacuum pumps or rotary vane vacuum pumps are usually used in traditional vacuum extruders, but the following technical problems generally exist in actual use: 1) The use of water ring vacuum pumps has low working vacuum, The problem of low pumping efficiency and high energy consumption; 2) When using a conventional slide valve or rotary vane oil-sealed vacuum pump, although the pumping efficiency is improved, the gas pumped out by the vacuum extruder contains a large amount of water vapor. There is a common problem that condensed water emulsifies the pump oil, which leads to the decline of pump performance; 3) The vacuum pump in the vacuum extruder works under the condition of large displacement for a long time, and the conventional slide valve or rotary vane oil seal vacuum pump sprays The oil phenomenon is serious, resulting in a large loss of pump oil consumption and serious environmental pollution; 4) The vacuum extruder works in an outdoor environment, and usually lacks qualified industrial circulating cooling water. On-site operations bring difficulties; 5) The ambient temperature varies greatly in different regions and seasons, which will also lead to significant changes in the performance of the vacuum pump, such as the freezing and cracking of the water cooling jacket in winter in the north; 6) The vacuum extruder The exhaust air generally carries a lot of solid dust and sediment particles. Once it enters the vacuum pump, it will directly cause the wear and tear of the pump. The purification effect of the actual gas filtration equipment currently in use is not ideal.
