Description

A screw press for oil extraction from oilseeds Technical Field

[0001] The embodiments disclosed herein relate to the field of oil production technology, and more specifically, to a screw press for extracting oil from oilseeds. Background Technology

[0002] Screw presses are currently one of the most widely used oil pressing equipment. They have advantages such as large continuous processing capacity, short dynamic pressing time, high oil yield, thin and easy-to-crush cake, and low labor intensity of operation, making them particularly suitable for small and medium-sized oil processing enterprises.

[0003] CN209454228U discloses a screw press for oil production. The screw press includes a frame; a pressing mechanism; a fixed plate; a pneumatic rod; and a cleaning mechanism. The cleaning mechanism includes a storage box, a discharge plate, and a winding mechanism. The inner wall of the storage box is symmetrically provided with guide rails; springs are embedded inside the guide rails; the discharge plate is slidably embedded inside the storage box; and sliders are symmetrically provided on both side walls of the discharge plate, with the sliders slidably embedded inside the guide rails.

[0004] The aforementioned application document describes a method where a screw is driven by a drive housing to rotate, and the oil in the raw material is extracted under the pressure of the screw. The oil is then discharged through the discharge hopper. During the pressing process, the outer skin of the raw material is discharged through the slag discharge trough and then falls onto the slag discharge hopper a for discharge. The oil extracted may be blocked by the outer skin, making it difficult to discharge through the discharge hopper. At the same time, the oil is easily carried by the outer skin and discharged through the slag discharge trough, which is not conducive to oil collection. Therefore, improvements are needed. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an oil extraction screw press, which solves the technical problem in the prior art that the oil may be blocked by the outer skin after being pressed out, making it difficult to be discharged along the discharge hopper.

[0006] According to one aspect, at least one embodiment of this disclosure provides an oil extraction screw press for oil production, comprising: a worktable; a support frame fixedly connected to the top of the worktable; a machine body extending through and fixedly connected to the side of the support frame; a feed inlet extending through and fixedly connected to the top of the machine body; a liquid outlet and a waste pipe extending through and fixedly connected to the bottom of the machine body; a motor fixedly mounted on the side of the machine body; a rotating shaft extending through and rotatably connected to the interior of the machine body; screw pressing blades fixedly connected to the surface of the rotating shaft; an oil screening and discharging mechanism disposed inside the liquid outlet; and a shaking mechanism disposed on the top of the worktable. The feeding mechanism includes a fixed plate, a screen, a hydraulic chamber, and a connecting rod. The fixed plate is fixedly connected to the inner wall of the outlet. A spring telescopic rod is provided on the top of the fixed plate. The screen is slidably connected inside the outlet. The hydraulic chamber is penetrating and fixedly connected to the top of the worktable. A piston rod A is slidably connected to the piston inside one end of the hydraulic chamber. A gear is fixedly connected to the top of the piston rod A. A piston rod B is slidably connected to the piston inside the other end of the hydraulic chamber. The connecting rod is fixedly connected to the side end of the rotating shaft. A drive gear is fixedly connected to the end of the connecting rod away from the rotating shaft.

[0007] For example, in at least one embodiment of this disclosure, an oil extraction screw press is provided, which further includes: the liquid outlet is funnel-shaped, the waste pipe is L-shaped, the pressed oil is discharged through the liquid outlet, and the waste residue is discharged through the waste pipe.

[0008] For example, in at least one embodiment of this disclosure, an oil extraction screw press is provided, which further includes: the outer side of the screen is tightly fitted with the inner sidewall of the liquid outlet, and the top of the screen is initially level with the bottom of the machine body. When the pressed oil and waste pass through the screen, the oil will pass through the screen, while the waste will be blocked by the screen.

[0009] For example, in at least one embodiment of this disclosure, an oil extraction screw press is provided, which further includes: the output shaft of the motor is fixedly connected to the end of the rotating shaft away from the connecting rod, and when the motor is started, it will drive the rotating shaft to rotate through its output shaft.

[0010] For example, in at least one embodiment of this disclosure, an oil extraction screw press is provided, which further includes: the end of the spring telescopic rod away from the fixed plate is fixedly connected to the bottom of the screen, and the spring on the spring telescopic rod is compressed when the screen moves downward.

[0011] For example, in at least one embodiment of this disclosure, an oil extraction screw press for oil production further includes: the teeth on the rack are initially engaged with the teeth on the drive gear, and the drive gear is an incomplete gear; when the drive gear rotates and its teeth engage with the teeth on the rack, it will drive the rack to move upward.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a shaking feeding mechanism, including: a pneumatic chamber and an eccentric ring, the pneumatic chamber being fixedly connected to the top of the worktable, one end of the pneumatic chamber being provided with an air bladder, the other end of the pneumatic chamber being internally connected to a piston slidingly with a push rod, the end of the push rod away from the pneumatic chamber being fixedly connected to an impact block, and the eccentric ring being fixedly connected to the surface of a connecting rod.

[0013] For example, in at least one embodiment of the present disclosure, an oil extraction screw press for oil production is provided, which further includes: the air bladder is initially in an inflated state, and the end of the air bladder away from the pressure chamber is close to the eccentric ring. When the eccentric ring rotates with the connecting rod, it will repeatedly squeeze the air bladder, and the air pressure inside the air bladder will enter the pressure chamber when it is squeezed.

[0014] For example, in at least one embodiment of this disclosure, an oil extraction screw press is provided, which further includes: the end of the impact block away from the push rod is initially close to the side of the waste pipe, and the impact block will impact the waste pipe when it moves to the left.

[0015] For example, in at least one embodiment of this disclosure, an oil-to-oil screw press is provided, which further includes: the impact block is generally circular, and the impact block is made of rubber, so that the circular rubber impact block will not damage the waste pipe when it impacts the waste pipe.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] This disclosure incorporates a screening and oil extraction mechanism. By turning on the motor to drive the rotating shaft, the rotating shaft drives the spiral pressing blades to press the raw materials. During this process, the screen is repeatedly moved downwards and bounced upwards by the cooperation of components such as the drive gear, rack, and hydraulic chamber. This allows the waste material and the extracted oil to be better screened, improving oil extraction efficiency and reducing the possibility of the extracted oil being carried away by the waste material and discharged from the waste pipe.

[0018] In this disclosure, a shaking feeding mechanism is provided, which enables the motor to drive the rotating shaft to rotate. During the process of the rotating shaft driving the spiral pressing blades to press the raw material, the impact block is repeatedly hit by the eccentric ring, air bag, air pressure chamber and other components. The repeated impact of the impact block causes the waste pipe to vibrate slightly, preventing the waste from staying in the waste pipe. Attached Figure Description

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] As shown in Figures 1 to 5, an oil extraction screw press according to an embodiment of this disclosure is illustrated, comprising: a workbench 1, a support frame 2 fixedly connected to the top of the workbench 1, a body 3 connected through and fixedly connected to the side of the support frame 2, a feed inlet 4 connected through and fixedly connected to the top of the body 3, a liquid outlet 5 and a waste pipe 6 connected through and fixedly connected to the bottom of the body 3, a motor 7 fixedly mounted on the side of the body 3, a rotating shaft 8 rotatably connected through and rotatably connected to the inside of the body 3, screw pressing blades 9 fixedly connected to the surface of the rotating shaft 8, a screening and oil discharge mechanism 10 disposed inside the liquid outlet 5, and a shaking feeding mechanism 11 disposed on the top of the workbench 1; the screening and oil discharge mechanism 10 includes a fixed... The system includes a plate 101, a screen 103, a hydraulic chamber 104, and a connecting rod 108. The plate 101 is fixedly connected to the inner wall of the outlet 5. A spring telescopic rod 102 is provided on the top of the plate 101. The screen 103 is slidably connected to the inside of the outlet 5. The hydraulic chamber 104 is penetrating and fixedly connected to the top of the workbench 1. A piston rod A105 is slidably connected to the piston inside one end of the hydraulic chamber 104. A gear 106 is fixedly connected to the top of the piston rod A105. A piston rod B107 is slidably connected to the piston inside the other end of the hydraulic chamber 104. The connecting rod 108 is fixedly connected to the side end of the rotating shaft 8. A drive gear 109 is fixedly connected to the end of the connecting rod 108 away from the rotating shaft 8.

[0033] In some examples, the liquid outlet 5 is funnel-shaped and the waste pipe 6 is L-shaped. The extracted oil is discharged through the liquid outlet 5, while the waste residue is discharged through the waste pipe 6.

[0034] In some examples, the outer side of the screen 103 is in close contact with the inner wall of the liquid outlet 5, and the top of the screen 103 is initially level with the bottom of the machine body 3. When the pressed oil and waste pass through the screen 103, the oil will pass over the screen 103, while the waste will be blocked by the screen 103.

[0035] In some examples, the output shaft of motor 7 is fixedly connected to the end of shaft 8 away from connecting rod 108, and when motor 7 is started, it drives shaft 8 to rotate through its output shaft.

[0036] In some examples, the end of the spring telescopic rod 102 away from the fixed plate 101 is fixedly connected to the bottom of the screen 103, and the spring on the spring telescopic rod 102 is compressed when the screen 103 moves downward.

[0037] In some examples, the teeth on the rack 106 are initially engaged with the teeth on the drive gear 109, and the drive gear 109 is an incomplete gear. When the drive gear 109 rotates and its teeth engage with the teeth on the rack 106, it will cause the rack 106 to move upward.

[0038] For example, as shown in the figure, the raw material is fed into the machine body 3 through the feed inlet 4. The motor 7 is turned on, and the motor 7 drives the rotating shaft 8 to rotate through its output shaft. The rotation of the rotating shaft 8 drives the spiral pressing blades 9 to rotate and press the raw material. At the same time, the raw material is driven by the spiral pressing blades 9 to move towards the waste pipe 6. During this process, when the waste and the pressed oil pass through the screen 103, the waste is blocked by the screen 103, while the pressed oil will pass through the screen 103 and fall from the liquid outlet 5, completing the oil discharge. The waste continues to move and is finally discharged from the waste pipe 6. The rotation of the rotating shaft 8 also drives the connecting rod 108 to rotate. The rotation of the connecting rod 108 drives the drive gear 109 to rotate. At first, the rotation of the drive gear 109 and the meshing of its upper teeth with the upper teeth of the gear 106 will drive the gear 106 to move upward. The upward movement of the gear 106 will drive the piston rod A. When piston rod A105 moves upward, the hydraulic pressure in hydraulic chamber 104 drives piston rod B107 downward. The downward movement of piston rod B107 causes screen 103 to move downward, compressing the spring on spring telescopic rod 102. When the drive gear 109 rotates to the toothless part and disengages from the toothed rod 106, the spring on spring telescopic rod 102 rebounds, causing screen 103 to move upward and return to its original position. At this time, piston rod B107 also moves upward and returns to its original position. Piston rod A105 drives toothed rod 106 to move upward and return to its original position, thus forming a cycle. Screen 103 repeatedly moves downward and bounces upward and returns to its original position, which allows the waste material and the pressed oil to be better screened, improving oil extraction efficiency. It also reduces the possibility of the pressed oil being carried by the waste material and discharged from waste pipe 6.

[0039] As shown in Figures 1 to 5, a shaking feeding mechanism 11 in another embodiment of the present disclosure is shown, including: a pneumatic chamber 111 and an eccentric ring 115. The pneumatic chamber 111 is fixedly connected to the top of the workbench 1. An air bladder 112 is provided at one end of the pneumatic chamber 111. A push rod 113 is slidably connected to the piston inside the other end of the pneumatic chamber 111. An impact block 114 is fixedly connected to the end of the push rod 113 away from the pneumatic chamber 111. The eccentric ring 115 is fixedly connected to the surface of the connecting rod 108.

[0040] In some examples, the airbag 112 is initially inflated, and the end of the airbag 112 away from the pressure chamber 111 is close to the eccentric ring 115. When the eccentric ring 115 rotates with the connecting rod 108, it will repeatedly squeeze the airbag 112, and the air pressure inside the airbag 112 will enter the pressure chamber 111.

[0041] In some examples, the end of the impact block 114 away from the push rod 113 is initially close to the side of the waste pipe 6, and the impact block 114 will hit the waste pipe 6 when it moves to the left.

[0042] In some examples, the impact block 114 is circular in shape and made of rubber. When the circular rubber impact block 114 impacts the waste pipe 6, it will not cause damage to the waste pipe 6.

[0043] For example, as shown in the figure, when the connecting rod 108 rotates, it drives the drive gear 109 to rotate, which in turn drives the eccentric ring 115 to rotate. When the eccentric ring 115 rotates with the connecting rod 108, it repeatedly squeezes the airbag 112. When the airbag 112 is squeezed, the air pressure inside it enters the air pressure chamber 111, pushing the push rod 113 to the left. The push rod 113 moving to the left will drive the impact block 114 to move to the left and impact the waste pipe 6. Meanwhile, the eccentric ring 115 leaves the airbag 112. When the airbag 112 is not squeezed, the air pressure returns from the air pressure chamber 111 to the airbag 112. At this time, the air pressure drives the push rod 113 and the impact block 114 to move to the right to return to their original positions. The repeated impact of the impact block 114 causes the waste pipe 6 to vibrate slightly, preventing the waste from remaining in the waste pipe 6.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
