The vacuum pump can be used as a vacuumizing device in the industries of building materials, chemical engineering, medicine, electrnics, ceramics and the like, especially can be used as the slide-valve-type vacuum pump in the tile vacuum extruder. The slide-valve-type vacuum pump comprises an air intake filter, a pump body, a slide valve sleeve, an eccentric wheel, a conjoined slide block, a main shaft, a belt wheel, a belt, an electromotor, an exhaust valve, a side-sited oil tank, an exhaust oil mist filter, a pump oil circulation and oil temperature control device, a base seat and an electric control box; the air intake filter is installed at one side of the vacuum pump, and comprises an upper cylinder body, a lower cylinder body, a baffle plate, a coarse filter element and a fine filter element; the pump body is installed on the base seat; the pump body is provided with a pump cavity and the slide valve sleeve internally; the eccentric wheel is arranged in the slide valve sleeve and installed on the main shaft; the main shaft is installed on the pump body through a bearing; the end part of the main shaft at one side of the pump body is provided with a flywheel; and the end of the main shaft at the other side of the pump body is provided with the belt wheel; and the electromotor is installed on the base seat.

Description

technical field [0001] The invention relates to a sliding valve vacuum pump suitable for brick 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. Slide valve vacuum pump used in tile vacuum extruder. 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 convention...

AI Technical Summary

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.

[0003] The slide valve vacuum pumps currently used all have water jackets, and water is used to cool the pump body, which requires a large amount of cooling water, and the pump body is relatively large
