Problems solved by technology

When these food processing raw materials are prepared and transported, there will be a certain amount of gas in the material, but it is hoped to reduce the gas in the material as much as possible during food processing to ensure the quality of food processing. Exhaust the gas in the material, but the existing screw pump does not have this function

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the vacuum screw conveying pump provided by the present invention includes a feed chamber 5 and a discharge chamber 6 that communicate with each other. Port 7, wherein the other side of the feed chamber 5 relative to the discharge chamber 6 communicates with the vacuum chamber 3, the vacuum chamber 3 is provided with an exhaust valve, and the other side of the vacuum chamber 3 is provided with a gear box 2, The screw rod driven by the motor 1 runs through the vacuum chamber 3 and the feeding chamber 5 in sequence.

[0015] Such as figure 2 As shown, the vacuum screw conveying pump provided in this embodiment includes two screw rods 10, the two screw rods run parallel to each other in the vacuum chamber 3 and the feeding chamber 5, the screw rods 10 are provided with a spiral body, and the two screw rods The ends o...

Abstract

The invention relates to a vacuum screw-rod conveying pump which comprises a feed cavity and a discharge cavity, wherein the feed cavity and the discharge cavity are mutually communicated; a feed inlet is arranged above the feed cavity, and an end of the discharge cavity is provided with a discharge outlet; the other side (opposite to the discharge cavity) of the feed cavity is communicated with a vacuum cavity, the vacuum cavity is provided with an air release valve, a screw rod driven by a motor sequentially passes through the vacuum cavity and the feed cavity, and the screw rod is provided with a spiral body. In the vacuum screw-rod conveying pump provided by the invention, through utilizing the motion mode of the screw rod and setting the vacuum cavity on one side of the feed cavity, the removal of air in materials is facilitated; and because the spiral thrusting force offsets a vacuum attractive force, materials are uneasy to enter into the vacuum cavity, and only air is pumped out. The vacuum screw-rod conveying pump can be used for conveying various materials, and therefore, the vacuum screw-rod conveying pump is wide in viscosity range, large in output volume, stable in conveying and high in operating efficiency.

Description

technical field [0001] The invention is applicable to the structural design of all screw conveying pumps, and is specifically a vacuum screw conveying pump designed by combining vacuum technology and screw conveying principles. Background technique [0002] Screw conveying pumps are widely used and involve many industrial fields, such as chemical industry, mining and metallurgy, pharmaceutical field, food processing field and so on. Because the screw conveying pump has the characteristics of no pulse, no stirring, and stable conveying, in the food processing industry, the screw conveying pump is often used to convey various processing materials, such as minced meat, cheese, jam, vegetable juice, etc. When these food processing raw materials are prepared and transported, there will be a certain amount of gas in the material, but it is hoped to reduce the gas in the material as much as possible during food processing to ensure the quality of food processing. The gas in the ma...
