Description

TECHNICAL FIELD

[0001] The utility model relates to oil press equipment field, concretely relates to a spiral oil press cake outlet protection structure. BACKGROUND

[0002] The spiral oil press is a kind of equipment widely used in plant oil production, can efficiently extract oil from oil crops. Its working principle is that oil is pressed in the press bore by the rotation of the spiral shaft, so that oil is separated from oil crops, and the residue (i.e. cake residue) after pressing is discharged through the cake outlet.

[0003] Under normal working conditions, the spiral oil press can stably carry out oil extraction and cake residue discharge. However, in the actual use process, due to various reasons, such as high water content of oil, uneven distribution of materials or equipment wear, the oil press may run poorly, and the pressure in the press bore may abnormally rise. When the pressure in the press bore is too large, the equipment needs to be relieved to avoid damaging the equipment or affecting the production efficiency. However, the existing equipment has the problem that cake residue or oil may splash from the cake outlet when relieved, which not only wastes resources, but also may cause safety hazards to the operator, based on which, we propose a spiral oil press cake outlet protection structure.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] The present embodiment provides a screw oil press cake outlet protection structure, which comprises a side plate, a side sealing plate, a discharge cavity, a fixed plate, a movable plate, a top sealing plate and a bottom sealing plate. Figures 1 to 5As shown, it comprises two side plates 1 arranged side by side, two side sealing plates 2 symmetrically arranged between the two side plates 1, and a discharging cavity 3 formed between the side plates 1 and the side sealing plates 2, which communicates with the cake outlet of the screw oil press. An opening is arranged at the upper part between the two side sealing plates 2, which communicates with the external environment and is used for discharging the water vapor volatilized at the cake outlet end of the oil press. A cake outlet is arranged at the lower part between the two side sealing plates 2. In actual use, when the pressure in the pressing chamber is too high, the equipment needs to be depressurized. On the one hand, the depressurization operation can cause the cake residue and residual oil to be sprayed out at a high speed from the cake outlet, which can easily pollute the surrounding environment. On the other hand, the splashing of the cake residue and oil can also pose a safety risk to the operator, such as burns or slips, which increases the unsafe factors in production. Therefore, the side sealing plate 2 is designed as a spliced structure composed of a fixed plate 21 and a top sealing plate 23. The two fixed plates 21 are fixedly connected with the side plates 1, and the two top sealing plates 23 are symmetrically arranged around the opening. The top sealing plate 23 is slidingly installed on the fixed plate 21. During the depressurization operation, the two top sealing plates 23 move synchronously towards the opening until the opening is completely closed, so that the discharging cavity 3 forms a relatively closed space, forming a protective barrier to prevent the cake residue and oil from being directly splashed out, effectively solving the splashing problem and improving the safety of the operator.

[0027] In this embodiment, the fixed plate 21 and the top sealing plate 23 are both arc-shaped structures. The inner side end face of the top sealing plate 23 is provided with a sliding rail, and the outer side end face of the fixed plate 21 is provided with a sliding groove matched with the sliding rail. The sliding rail is slidingly assembled in the sliding groove. During the depressurization operation, the two top sealing plates 23 move towards the opening along the arc surface of the corresponding fixed plate 21 until the opening is completely closed. The arc-shaped top sealing plate 23 blocks the discharging cavity 3, maximizes the size of the discharging cavity 3, and is beneficial to subsequent depressurization operation.

[0028] During the depressurization operation, if the volume of the discharging cavity 3 remains unchanged, it means that the amount of discharged residue is limited, and the high pressure inside cannot be effectively relieved. Therefore, the volume of the discharging cavity 3 is designed to be variable. During the depressurization operation, the volume of the discharging cavity 3 increases. Specifically, the lower end of the fixed plate 21 is rotationally connected with an activity plate 22. During the depressurization operation, the two activity plates 22 move synchronously towards the opening, so that the volume of the discharging cavity 3 increases, the residue can be discharged faster and more effectively, the pressure in the pressing chamber is rapidly reduced, and the timeliness of the depressurization operation is ensured.

[0029] On the basis of the above scheme, we use the outward movement of the movable plate 22 to realize the movement of the top sealing plate 23 along the arc surface of the fixed plate 21 towards the direction close to the opening. Specifically, the outer end surface of the movable plate 22 is rotatably provided with a first connecting rod 231, the other end of the first connecting rod 231 is rotatably connected with a second curved rod 232, and the other end of the second curved rod 232 is rotatably connected with the top sealing plate 23. When the movable plate 22 rotates towards the direction away from the opening, the first connecting rod 231 rotates outward synchronously with the movable plate 22, the end of the first connecting rod 231 pushes the second curved rod 232 to move, and the end of the second curved rod 232 drives the top sealing plate 23 to move along the arc surface of the fixed plate 21 towards the direction close to the opening. It should be noted that the first connecting rod 231 and the movable plate 22 form a first hinge point, and the second curved rod 232 and the top sealing plate 23 form a second hinge point. When the movable plate 22 rotates outward, the distance between the first hinge point and the second hinge point becomes smaller, and the rotation angle of the first connecting rod 231 is limited and cannot continue to rotate outward, resulting in that the end of the first connecting rod 231 can only apply a force to the second curved rod 232, i.e. the first connecting rod 231 rotates inward, so that the second curved rod 232 as a whole moves towards the direction away from the first connecting rod 231, thereby pushing the top sealing plate 23 to move towards the direction close to the opening.

[0030] In addition, in order to ensure that the discharging cavity 3 forms a relatively closed space when pressure relief, a bottom sealing plate 24 is installed below the movable plate 22, the lower end surface of the movable plate 22 and the upper end arc surface of the bottom sealing plate 24 are in sliding contact, the bottom sealing plate 24 is fixedly connected with the side plate 1, and gaps exist between the two bottom sealing plates 24 to ensure the smoothness of the cake outlet.

[0031] In order to realize the synchronous rotation of the two movable plates 22 towards the direction away from the opening, a wedge-shaped block inclined surface driving mode is adopted in this embodiment. Specifically, the side surface of the movable plate 22 is provided with a guide rod 221, the guide rod 221 extends to the outside of the side plate 1, a driving plate 222 is slidably assembled between the two guide rods 221 in the vertical direction, the contact area between the driving plate 222 and the guide rod 221 is provided with an inclined surface 223 with an outer width and an inner width, and the guide rod 221 is in sliding contact with the inclined surface 223. In the initial state, the movable plate 22 is in a vertical state due to its own weight, and when pressure relief is performed, the driving plate 222 moves downward in the vertical direction, and the guide rod 221 moves outward under the extrusion action of the inclined surface 223, i.e. the synchronous outward movement of the two movable plates 22 is realized. In this embodiment, the movement of the driving plate 222 in the vertical direction is driven by an electric cylinder 224, the electric cylinder 224 is installed on the side plate 1, and the piston rod of the electric cylinder 224 is fixedly connected with the driving plate 222.

[0032] On the basis of the above scheme, in order to improve the stability of the movable plate 22 movement, we open the arc-shaped groove 11 in the side plate 1 corresponding to the guide rod 221, the guide rod 221 is slidingly assembled in the arc-shaped groove 11, and the movable plate 22 is guided to move outward along the arc-shaped groove 11 through the arc-shaped groove 11.
