Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0011] As shown in the figure: the spiral defoamer mainly includes two parts: the hub 1 and the paddle 2, the hub 1 is long cylindrical, the paddle 2 is helical, the paddle 2 has two pieces, two paddles The blades 2 are symmetrically arranged, and the inner edge of the blade 2 is welded to the outer wall of the hub 1 along the length direction of the hub 1 by spiral welding.

[0012] When working, the spiral defoamer rotates driven by the stirring shaft, and the central material liquid is pushed to the outer edge of the paddle 2 under the action of the forced thrust and centrifugal force of the helical surface of the paddle 2, and is sprayed to the liquid surface through the edge of the paddle 2 The foam layer plays the role of breaking the foam.

[0013] like Figure 1~Figure 3 As shown, the paddle 2 is drawn from a flat plate, the plane of the paddle 2 is a...

Abstract

The invention relates to a spiral defoamer which comprises a wheel hub and blades, and is characterized in that the wheel hub takes the shape of a long cylinder, the two spiral blades are symmetrically arranged, and the inner edges of the blades are spirally welded on the outer wall of the wheel hub along the length direction of the wheel hub. In the invention, the blades are symmetrically arranged to be spiral, when the defoamer rotates, central feed liquid is pushed to the outer edges of the blades under the actions of forced thrust of spiral surfaces of the blades and centrifugal force, and sprayed to a foaming layer on liquid surface through the edges of the blades, so as to play a role in breaking foam; planes of the blades are tapered spiral surfaces, linear speeds at the outer edges of the blades are different, and the feed liquid sprayed through the edges of the blades is covered on the foaming layer on the whole liquid surface, so as to achieve better defoaming effect; and the blades are simpler in structure, can be formed by drawing plates, does not need a mould for molding, can be manufactured to have different sizes and specifications according to needs, and is low in manufacturing cost.

Description

technical field [0001] The invention relates to a spiral defoamer for eliminating foam. Background technique [0002] In the industrial production process, the generation of foam often causes various troubles. If the foaming is serious, not only the production capacity will be reduced, but also the product quality will be reduced. Taking some method to eliminate foam can increase production, improve product quality, and prevent environmental pollution, so defoaming is an important issue. There are two types of defoaming methods commonly used in the production process: the chemical method of adding defoamers and the physical method of using mechanical defoamers. The commonly used mechanical defoamers include closed turbine defoamers, rake defoamers, scraper defoamers, etc. The closed turbine defoamer is more complicated to manufacture, and molds are required, and the diameters of the molds are different; the rake defoamer and scraper defoamer have poor adaptability. Cont...
