Description

Technical Field

[0001] The utility model relates to the technical field of pressing devices, in particular to a rapeseed oil pressing device. Background Art

[0002] Rapeseed oil pressing refers to the process of separating the oil from rapeseed through mechanical equipment. In this process, rapeseed is pressed to release the oil, and then filtered and other steps are used to extract pure rapeseed oil.

[0003] Existing rapeseed oil pressing usually extracts rapeseed oil through mechanical pressing. The specific process includes steps such as rapeseed cleaning, crushing, cooking, pressing, and filtering. After filtration, the oil in the "oil cake" (i.e., the solid residue produced by pressing) produced during the pressing process is extracted using an extraction process.

[0004] However, in the prior art, the pressing process is usually only implemented by mechanical pressing, which makes it impossible for the rapeseed to be fully pressed, and the deep oil cannot be fully exposed to the extractant, which causes a part of the oil to remain in the rapeseed and cannot be effectively extracted, affecting the final yield and quality; in addition, too much oil residue in the residue will inevitably require more extractant, affecting the production cost, and it is necessary to propose a rapeseed oil pressing device with a residue recovery function. Utility Model Content

[0005] The purpose of the utility model is to provide a rapeseed oil pressing device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A rapeseed oil pressing device comprises a first shell and a second shell; the second shell is fixedly connected to the top of the first shell, a pressing component is arranged inside the second shell, the pressing component is used for pressing by physical pressing, a re-pressing component is arranged inside the first shell, the re-pressing component is used for mutually pressing the pressed materials, a transmission component is arranged between the first shell and the second shell, the transmission component is used for realizing power transmission between the pressing component and the re-pressing component.

[0008] By adopting the above technical scheme, by arranging a pressing component and a re-pressing component for cooperation, the rapeseed can be physically pressed by the pressing component first, so that the rapeseed structure is destroyed and residues are produced, and then the re-pressing component can be used to squeeze the residues against each other to squeeze out the oil in the residues, thereby greatly improving the effect of rapeseed oil pressing and the oil yield of rapeseed oil under physical means.

[0009] A further improvement of the technical solution of the utility model is that: the re-pressing component includes a filter cartridge, which is fixedly connected between two sides of the inner wall of the first shell, a rotating shaft is rotatably connected between the inner walls of the first shell and located inside the filter cartridge, a spiral is provided on the outside of the rotating shaft, and the spiral gradually decreases in spacing along the axial direction of the rotating shaft, a secondary loading hopper is fixedly connected to the top of the first shell, the bottom of the secondary loading hopper extends to the interior of the filter cartridge, a slag discharge pipe is provided on one side of the bottom of the first shell, a slag discharge port is provided at the bottom of the filter cartridge and above the slag discharge pipe, a partition is fixedly connected between the inner walls of the first shell, and an oil discharge pipe is provided on the side of the bottom of the first shell away from the slag discharge pipe.

[0010] By adopting the above technical solution, the spiral rotates by rotating the rotating shaft, and the outer side of the spiral fits against the inner wall of the filter cartridge. The slag is transported during the rotation. Since the pitch of the spiral gradually decreases, the feeding speed of the slag in the front (close to the slag outlet) is lower than that in the rear during the transportation process. Therefore, the slag in the rear will squeeze the slag in the front, and then the slag will squeeze each other, further squeezing out the oil.

[0011] A further improvement of the technical solution of the utility model is that: the pressing assembly includes two pressing rollers, the two pressing rollers are symmetrically rotatably connected between the inner walls of the second shell, a motor is fixedly installed on one side of the second shell, one end of the central axis of the two pressing rollers extends to the outside of the second shell and is fixedly connected to gears, the two gears are meshed with each other, the other end of the central axis of one of the pressing rollers extends to the outside of the second shell and is fixedly connected to the output end of the motor, and a feeding hopper is arranged on the top of the second shell.

[0012] By adopting the above technical solution, the motor is controlled to drive the two pressing rollers to rotate in coordination with each other to achieve the pressing of rapeseed oil. The pressing rollers can use the narrow gap to destroy the rapeseed structure and squeeze out the oil.

[0013] A further improvement of the technical solution of the utility model is that: the transmission assembly includes a support frame, the support frame is fixedly connected to one side of the second shell, one side of the support frame is rotatably connected to a first pulley, the central axis of the first pulley extends to the other side of the support frame and is fixedly connected to the central axis of one of the gears, one end of the rotating shaft extends to the outside of the first shell and is fixedly connected to a second pulley, and the first pulley and the second pulley are connected by a transmission belt.

[0014] By adopting the above technical solution, during the pressing process, the gear provides transmission and drives the first pulley to rotate, and drives the second pulley to rotate through the belt transmission, thereby driving the rotating shaft to rotate, so that the spiral rotates.

[0015] A further improvement of the technical solution of the utility model is that a discharge port is provided at the bottom of the first shell, a sieve plate is suspended at the bottom of the first shell through a tension spring, the sieve plate is inclined, the bottom of the sieve plate is located above the secondary upper hopper, a transfer hopper is provided on the top of the first shell, and a guide plate is fixedly connected between the inner walls of the first shell and above the filter cartridge.

[0016] By adopting the above technical solution, the rapeseed falls from the discharge port onto the sieve plate after being pressed, and is filtered by the sieve plate, so that the solid residue falls into the secondary hopper, while the oil passes through the sieve plate and flows downward along the guide plate.

[0017] A further improvement of the technical solution of the utility model is that the bottom of the inner wall of the first shell is set as an inclined surface, and the oil outlet pipe is located at the lowest part of the inclined surface.

[0018] By adopting the above technical solution, the squeezed oil can pass through the filter cartridge and flow along the inclined surface of the bottom of the first shell and flow out from the oil outlet pipe.

[0019] A further improvement of the technical solution of the utility model is that the motor is electrically connected to the external control device.

[0020] The above technical solution makes it easy to control the operation of the motor through an external control device.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides a rapeseed oil pressing device. By arranging a pressing component and a re-pressing component for cooperation, the pressing component can be used to physically press the rapeseed, so that the structure of the rapeseed is destroyed and residues are produced. Then, the re-pressing component can be used to squeeze the residues against each other to squeeze out the oil in the residues, thereby greatly improving the effect of rapeseed oil pressing, and improving the oil yield of rapeseed oil under physical means, which is beneficial to practical applications.

[0023] 2. The utility model provides a rapeseed oil pressing device, which can transport the residue and generate pressure by setting spirals with gradually decreasing spacing, so that the residue is squeezed against each other, further fully squeezing out the oil, and compensating for the problem of insufficient oil output during the external squeezing process.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the embodiments:

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, the utility model provides a rapeseed oil pressing device, including a first shell 1 and a second shell 2; the second shell 2 is fixedly connected to the top of the first shell 1, a pressing component is arranged inside the second shell 2, the pressing component is used for pressing by physical pressing, a re-pressing component is arranged inside the first shell 1, the re-pressing component is used for mutually pressing the pressed materials, a transmission component is arranged between the first shell 1 and the second shell 2, the transmission component is used for realizing power transmission between the pressing component and the re-pressing component.

[0034] In this embodiment, by arranging a pressing component and a re-pressing component for cooperation, the pressing component can be used to first physically press the rapeseed, so that the rapeseed structure is destroyed and residues are produced, and then the re-pressing component can be used to squeeze the residues against each other to squeeze out the oil in the residues, thereby greatly improving the effect of rapeseed oil pressing and the oil yield of rapeseed oil under physical means, which is beneficial to practical applications.

[0035] Example 2

[0036] like Figure 3 and Figure 4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the re-pressing component includes a filter cartridge 3, the filter cartridge 3 is fixedly connected between the two sides of the inner wall of the first shell 1, and a rotating shaft 4 is rotatably connected between the inner walls of the first shell 1 and located inside the filter cartridge 3.

A secondary loading hopper 6 is fixedly connected to the top of the first shell 1, and the bottom of the secondary loading hopper 6 extends to the inside of the filter cartridge 3. A slag discharge pipe 7 is provided on one side of the bottom of the first shell 1, and a slag discharge port 10 is provided at the bottom of the filter cartridge 3 and above the slag discharge pipe 7.

[0037] In this embodiment, the spiral 5 is rotated by rotating the rotating shaft 4, and the outer side of the spiral 5 is in contact with the inner wall of the filter cartridge 3. The slag is transported during the rotation. Since the spacing of the spiral 5 gradually decreases, the slag feeding speed at the front (close to the slag outlet 10) is lower than that at the rear during the transportation process. Therefore, the slag at the rear will squeeze the slag at the front, and then the slag will squeeze each other, further squeezing out the oil.

[0038] Example 3

[0039] like Figure 2 and Figure 5 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the pressing assembly includes two pressing rollers 12, the two pressing rollers 12 are symmetrically rotatably connected between the inner walls of the second shell 2, a motor 13 is fixedly installed on one side of the second shell 2, one end of the central axis of the two pressing rollers 12 extends to the outside of the second shell 2 and is fixedly connected to a gear 14, the two gears 14 are meshed with each other, the other end of the central axis of one of the pressing rollers 12 extends to the outside of the second shell 2 and is fixedly connected to the output end of the motor 13, and a feeding hopper 11 is arranged on the top of the second shell 2.

[0040] In this embodiment, the motor 13 is controlled to work and drive the two pressing rollers 12 to rotate in coordination with each other to achieve the pressing of rapeseed oil. The pressing rollers 12 can use the narrow gap to destroy the structure of rapeseed and squeeze out the oil.

[0041] Example 4

[0042] like Figure 1 and Figure 2As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the transmission assembly includes a support frame 15, the support frame 15 is fixedly connected to one side of the second shell 2, one side of the support frame 15 is rotatably connected to a first pulley 16, the center axis of the first pulley 16 extends to the other side of the support frame 15 and is fixedly connected to the center axis of one of the gears 14, one end of the rotating shaft 4 extends to the outside of the first shell 1 and is fixedly connected to a second pulley 17, and the first pulley 16 and the second pulley 17 are connected by a transmission belt.

[0043] In this embodiment, during the squeezing process, the gear 14 provides transmission and drives the first pulley 16 to rotate, and drives the second pulley 17 to rotate through the belt transmission, thereby driving the rotating shaft 4 to rotate, so that the screw 5 rotates.

[0044] like Figure 1 and Figure 2 As shown, preferably, a discharge port is provided at the bottom of the first shell 1, a sieve plate 18 is suspended at the bottom of the first shell 1 through a tension spring, the sieve plate 18 is inclined, the bottom of the sieve plate 18 is located above the secondary upper hopper 6, a transfer hopper 19 is provided at the top of the first shell 1, and a guide plate 20 is fixedly connected between the inner walls of the first shell 1 and above the filter cartridge 3.

[0045] In this embodiment, the rapeseed falls from the discharge port onto the sieve plate 18 after being pressed, and is filtered by the sieve plate 18 , so that the solid residue falls into the secondary upper hopper 6 , while the oil passes through the sieve plate 18 and flows downward along the guide plate 20 .

[0046] like Figure 3 As shown, preferably, the bottom of the inner wall of the first housing 1 is set as an inclined surface, and the oil outlet pipe 8 is located at the lowest part of the inclined surface.

[0047] In this embodiment, the squeezed oil is allowed to pass through the filter cartridge 3 and flow along the inclined surface of the bottom of the first housing 1 and flow out from the oil outlet pipe 8 .

[0048] Preferably, the motor 13 is electrically connected to an external control device.

[0049] In this embodiment, it is convenient to control the operation of the motor 13 through an external control device.

[0050] The working principle of the rapeseed oil pressing device is described in detail below.

[0051] like Figure 1-5As shown, rapeseed oil is added to the second housing 2 through the hopper 11, and the motor 13 is controlled to work, driving the two pressing rollers 12 to rotate in cooperation with each other to achieve the pressing of rapeseed oil. The pressing rollers 12 can use the narrow gap to destroy the structure of rapeseed and squeeze out the oil, and the oil falls from the discharge port onto the sieve plate 18, and is filtered by the sieve plate 18, so that the solid residue falls into the secondary upper hopper 6, and the oil passes through the sieve plate 18 and flows downward along the guide plate 20; during the pressing process, the gear 14 provides transmission and drives the first A pulley 16 rotates, and drives the second pulley 17 to rotate through the belt transmission, and then drives the rotating shaft 4 to rotate, so that the spiral 5 rotates, and the outer side of the spiral 5 fits with the inner wall of the filter cylinder 3. The slag is transported during the rotation. Since the spacing of the spirals 5 gradually decreases, the feeding speed of the slag in the front (close to the slag outlet 10) is lower than that in the rear during the transportation process. Therefore, the slag in the rear will squeeze the slag in the front, and then the slags are squeezed against each other, and the oil is further squeezed out, which greatly improves the effect of oil extraction.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
