Description

Technical Field

[0001] The utility model belongs to the technical field of oil pressing, and particularly relates to a screw oil press. Background Art

[0002] The screw oil press is a widely used oil pressing device internationally. It realizes continuous oil pressing through the pushing action of a rotating screw shaft in the pressing chamber. However, the existing screw oil presses have problems such as low oil yield, high energy consumption, and damage to the quality of oilseeds. Currently, most of the common screw oil presses on the market adopt traditional structural designs. Although they can achieve the basic oil pressing function, they perform poorly in dealing with different oilseeds, improving the oil yield, and reducing energy consumption. During the oil pressing process of traditional screw oil presses, due to the limitations of structural design and process parameters, the temperature of the oilseeds during pressing is likely to be too high, thus affecting the quality of the oil products. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a screw oil press for the above-mentioned existing technical problems, achieving a cooling effect.

[0004] In view of this, the utility model provides a screw oil press, which includes a support frame and an oil pressing box on the support frame, and further includes a cooling component. The cooling component is arranged on the top of the oil pressing box and cools the inside of the oil pressing box; a pressing chamber, which is arranged in the oil pressing box; and a pressing screw, which is movably arranged in the pressing chamber.

[0005] In this technical solution, during the oil pressing process, the pressing screw squeezes and frictions the oilseeds to generate high temperature. The cooling component cools the pressing chamber and the pressing screw in the oil pressing box, so that the oilseeds are not affected by high temperature during pressing.

[0006] In the above technical solution, further, the cooling component includes a cooling fan. The cooling fans are arranged in a linear array on the top of the oil pressing box. A condensing pipe is arranged between the cooling fan and the pressing chamber. The condensing pipe is arranged in the oil pressing box, and the condensing pipe penetrates out of the oil pressing box and is connected to a liquid-changing cooling box.

[0007] In this technical solution, the condensing pipe exchanges heat with the air in the oil pressing box through the cooling medium flowing into it, reducing the temperature of the air in the oil pressing box. The cooling fan blows the cold air towards the pressing chamber. The wind force provided by the cooling fan is not sufficient to provide centripetal force for the oil droplets, and the temperature of the pressing screw in the pressing chamber also drops under the influence of the pressing chamber, improving the overall temperature reduction efficiency in the oil pressing box. The liquid-changing cooling box is a known technology in the art and will not be elaborated.

[0008] In the above technical solution, further, the pressing chamber includes fixing strips. The fixing strips are arranged in a circumferential array on the surface of the pressing screw. There is a gap between two fixing strips. The fixing strips are sleeved with mounting frames, and the mounting frames are fixedly arranged in the oil pressing box.

[0009] In this technical solution, the fixing bars are circumferentially arrayed to wrap the pressing screw. The gaps between the fixing bars enable the separation of the oil material and the pressed oil, which not only quickly contacts the cold air but also increases the oil yield of the oil material. The mounting frame sleeves the fixing bars on the surface of the pressing screw, and the mounting frame fixes the pressing chamber composed of the mounting frame and the fixing bars in the pressing box.

[0010] In the above technical solution, further, the side shape of the fixing bar is trapezoidal, and there is a gap between two adjacent fixing bars, and the gap becomes larger and larger along the diffusion direction of the circular axis of the pressing screw.

[0011] In this technical solution, the shape setting of the fixing bars is conducive to the outflow of the oil in the oil material, improving the oil extraction efficiency. The wind blown by the cooling fan is more likely to contact the pressing screw, improving the temperature drop efficiency.

[0012] In the above technical solution, further, it includes a diversion box. The diversion box is arranged at the bottom of the pressing box, and an oil outlet pipe is arranged at the bottom of the diversion box.

[0013] In this technical solution, the diversion box not only protects the oil droplets falling everywhere affected by the cold air but also plays a role in diverting the pressed oil.

[0014] In the above technical solution, further, it includes a processing component. The processing component includes a processing box. The processing box is arranged on the outer wall of the pressing box, and the processing box is provided with a crushing unit, and the crushing unit crushes the pressed oil cake.

[0015] In this technical solution, the processing box receives the pressed oil cake. When the crushing unit crushes the oil cake, the processing box blocks the flying of the crushed debris.

[0016] In the above technical solution, further, the crushing unit includes pneumatic telescopic rods. Two pneumatic telescopic rods are symmetrically arranged on the outer wall of the processing box. The output end of the pneumatic telescopic rod passes through the outer wall of the processing box and is connected with a movable frame. First sliders are fixedly arranged on both sides of the movable frame, and the first sliders are slidably arranged in the first chutes. The first chutes are arranged on the processing box, and crushing rollers are symmetrically and movably arranged on the movable frame.

[0017] In this technical solution, the pneumatic telescopic rod drives the movable frame to slide inside the processing box, and the movable frame drives the crushing roller to slide. The surface of the crushing roller is attached to the discharge port of the pressing box at the bottom, and the movable plate is provided to prevent the length of the oil cake from being too long. The movable plate cooperates with the crushing roller to crush the oil cake. The oil cake after oil pressing rotates out from the discharge port of the pressing box, and the crushing roller rotates relative to the oil cake, preventing the oil cake debris from blocking between the crushing roller and the movable plate. After processing, the pneumatic telescopic rod drives the movable frame to slide back, making it easier to clean later.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. By setting the cooling component, the condensing pipe exchanges heat with the cooling medium flowing into it and the air inside the pressing box, reducing the temperature of the air inside the pressing box. The cooling fan blows the cold air towards the pressing chamber, and the pressing screw inside the pressing chamber is also affected by the temperature drop of the pressing chamber, improving the overall temperature drop efficiency inside the pressing box.

[0020] 2. By setting the pressing chamber, the gap between the fixing strips separates the oil material and the pressed oil. It not only quickly contacts the cold air but also improves the oil output of the oil material. The mounting frame fixedly sets the pressing chamber composed of the mounting frame and the fixing strips inside the pressing box.

[0021] 3. By setting the processing component, the processing box receives the oil cake after pressing, and the crushing roller squeezes the oil cake to break it. The processing box blocks the flying of the crushed debris. Description of the Drawings
