Cake discharge protective structure of spiral oil press

Abstract

The invention discloses a cake discharge protective structure of a spiral oil press. The cake discharge protective structure comprises a back end plate (1), spiral shafts (2) and a protective device, wherein one end of each spiral shaft (2) is nested on the back end plate (1), and a cake discharge hole (11) is formed between each spiral shaft (2) and the back end plate (1); the protective device comprises a protective cover (3) which is fixedly mounted on the back end plate (1) through a bolt or a lock catch and located in the positions of the cake discharge holes (11); a discharge opening (31) is formed in the lower part of the protective cover (3); observation windows (32) are arranged on the left side and the right side of the protective cover (3); and transparent plates (33) are arranged in the positions, corresponding to the observation windows (32), of the protective cover (3). With the adoption of the cake protective structure of the spiral oil press, a field worker can be effectively protected; steam can be discharged in time; the cake discharge thickness can be adjusted in time; and simultaneously, an oil pressing field is kept clean and hygienic.

Description

technical field [0001] The invention relates to a screw oil press, in particular to a cake-out protection structure for the screw oil press. Background technique [0002] The screw oil press is a machine that continuously pushes the raw material forward in the press chamber and extracts crude oil under the action of dynamic extrusion. Almost all oil crops can be pressed by screw presses, such as tea seeds, peanuts, soybeans, sunflowers, rapeseeds, walnuts, cottonseeds, etc., can be pressed by screw presses, which are widely used. [0003] Most of the current screw oil presses do not have any protection at the outlet of the cake. When the press is not running smoothly, the pressure in the press chamber is too high, and when the pressure is released, the cake residue or oil will fly directly from the outlet of the cake, which is very easy to cause damage to the site. People were injured, and the sanitation of on-site operations was affected. There are also groove-shaped seal...

Problems solved by technology

[0003] Most of the current screw oil presses do not have any protection at the outlet of the cake. When the press is not running smoothly, the pressure in the press chamber is too high, and when the pressure is released, the cake residue or oil will fly directly from the outlet of the cake, which is very easy to cause the on-site Personnel are injured and affect the sanitation of on-site operations

There are also groove-shaped sealing baffles installed at the cake outlet, that is, a baffle is installed on the left, right, front, and upper sides of the cake outlet of the screw shaft. This structure prevents the cake from splashing, but its existence The following problems: when the moisture in the billet is high, the water vapor volatilized by the oil cake after extrusion is blocked from being discharged from the groove-shaped sealing baffle; it is also impossible to directly observe the situation of the cake from outside the baffle, and the thickness of the cake cannot be adjusted in time
