Description

Technical Field

[0001] The invention relates to the field of soybean softening equipment, in particular to a soybean softening pretreatment device for soybean oil production. Background Art

[0002] In existing soybean oil production, soybean softening pretreatment utilizes a horizontal softening pot with an outer jacketed layer for heating. However, the pot relies solely on external heating, lacking a central heating element along its axis. This results in a slow temperature rise within the pot and uneven heating of the soybeans, impacting softening efficiency and quality. Furthermore, multiple spiral propellers are intermittently installed within the pot, both for stirring and to propel the material toward one end. However, the horizontal pot orientation concentrates water injection at the bottom during cleaning, making it difficult to fully flush the inner walls and the gaps between the propellers. This results in poor cleaning efficiency and slow cleaning, and can easily lead to residual material that affects subsequent processing. Summary of the Invention

[0005] Optionally, a plurality of discharge pipes are provided on the circumferential side wall of the softening pot away from the feed port and are spaced at equal angles around the axis of the softening pot. The end of the discharge pipe away from the inner cavity of the softening pot passes through the jacket layer and extends to the outside of the jacket layer; the inner edge of the discharge pipe close to the end of the inner cavity of the softening pot is arranged in a conical surface, and the open part of the conical surface is connected to the inner wall of the softening pot away from the feed port.

[0006] Optionally, the liquid outlet end of the inner sleeve is rotatably connected to the side wall of the softening pot away from the feed port through a bearing, and a sub-bracket is fixed to the outer wall of the softening pot close to the feed port, and the liquid inlet end of the inner sleeve is rotatably connected to the sub-bracket through a bearing; the liquid outlet end of the inner sleeve is rotatably connected to a medium connecting head through a sealing bearing, and the medium connecting head is hollow, and a circular hole is provided at the center of the liquid outlet end of the inner sleeve, and the inner cavity of the inner sleeve is connected to the medium connecting head through the circular hole; a plurality of first conducting tubes are fixed on the side wall of the medium connecting head at equal angles around the axis of the inner sleeve, and the other end of the first conducting tube is fixed to the jacket layer and connected to the heating chamber.

The inner sleeve first heats the middle part of the pot body and then introduces the medium into the jacket layer through the first conducting pipe, thereby accelerating the heating speed in the pot and solving the problem of uneven heating caused by traditional circumferential heating only. At the same time, a high-pressure liquid spraying structure is provided on the inner sleeve, which, in conjunction with the rotation of the pot body, can flush the inner wall of the softening pot in all directions, avoiding the disadvantage of water concentrating on the lower part when cleaning the horizontal pot body, thereby improving the cleaning effect and efficiency. The present invention adopts the mechanical linkage structure of the push rod, the drive rod and the valve handle, abandons the solenoid valve control, and realizes the path switching by manual drive of the screw and the threaded sleeve: on the one hand, it avoids the circuit failure or sealing failure problem that the solenoid valve is prone to in high temperature and humid environment, and reduces the frequency and cost of equipment maintenance; on the other hand, the directness of the mechanical transmission makes the path switching response more stable, and will not cause the action delay due to electromagnetic interference, ensuring the accurate and reliable switching of the heating and cleaning modes, and adapting to the complex working conditions of the soybean softening workshop with high dust and high humidity.

[0011] The present invention achieves the dual effects of cleaning and central heating through the inner sleeve, without the need to additionally set up independent central heating tubes and cleaning tubes, reducing the number of components in the pot, lowering the structural complexity and equipment cost; at the same time, the sharing of the inner sleeve enables the switching of heating and cleaning to be completed through the same on-off device, and the two share the same installation space, avoiding the problem of material flow obstruction caused by multiple components occupying the space in the pot, taking into account both heating efficiency and cleaning effect, while improving the compactness and operation smoothness of the equipment.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1 to 8 The present embodiment provides a soybean softening pretreatment device for soybean oil production, comprising a base 1, on which a horizontal softening pot 2 is mounted, a group of rollers symmetrically provided at both ends of the base 1, supporting rings fixed at both ends of the softening pot 2, each supporting ring being rotatably mounted on a group of rollers, a group of transverse limiting wheels symmetrically provided at both ends of the base 1, and two limiting wheels in each group respectively abutting against the two sides of the supporting ring, thereby limiting the axial displacement of the softening pot 2 and ensuring that the softening pot 2 rotates stably on the base 1 to turn the soybeans.

[0023] A jacket layer 3 is fixed to the circumferential outer wall of the softening pot 2. A closed heating chamber 4 is formed between the jacket layer 3 and the circumferential outer wall of the softening pot 2, through which a heating medium flows. The heating medium passes through the heating chamber 4, and the heat is transferred to the side wall of the softening pot 2, and then to the inner side of the softening pot 2, thereby heating and softening the soybean raw material inside the softening pot 2.

[0024] The rotation drive of the softening pot 2 is the same as the existing technology. A gear ring is fixed on the outer wall of the middle part of the jacket layer 3, and a motor is fixed on the base 1. A gear meshing with the gear ring is provided at the output end of the motor. By driving the motor, the gear drives the gear ring to rotate, thereby achieving the effect of driving the softening pot 2 to rotate.

[0025] A feed port 5 is provided in the middle of one end of the softening pot 2, and the soybean raw material feeding equipment feeds the soybean raw material into the softening pot 2 through the feed port. A plurality of spiral propulsion blades 6 are provided at intervals inside the softening pot 2. The propulsion blades 6 can stir the soybean raw material when the softening pot 2 rotates, and the propulsion blades 6 can be used to push the soybean raw material to one end of the softening pot 2 when the softening pot 2 rotates forward or over.

[0026] On the circumferential side wall of the softening pot 2 away from the feed port 5, a plurality of discharge pipes 7 are provided at equal angles around the axis of the softening pot 2. The end of the discharge pipe 7 away from the inner cavity of the softening pot 2 passes through the jacket layer 3 and extends to the outside of the jacket layer 3. During the softening stage, the discharge pipe 7 can be closed by a plug or other structure to prevent the soybean raw material from entering the discharge pipe 7. The structure of the plug or other structure for blocking the discharge pipe 7 can be used with existing mature technology. This is irrelevant to the improvement and innovation part of this application, so it is not shown in the figure and will not be described here. After the soybean raw material is softened, the discharge pipe 7 is opened and the softening pot 2 is driven to rotate. Under the action of the propulsion blade 6, the soybean raw material is churned in the softening pot 2 and pushed toward one side of the discharge pipe 7 and discharged from the discharge pipe 7.

[0027] The inner edge of the discharge pipe 7 near one end of the inner cavity of the softening pot 2 is set in a conical surface, and the open part of the conical surface is connected with the inner wall of the end of the softening pot 2 away from the feed port 5. By connecting with the inner wall of the end of the softening pot 2, the soybean raw material can fully enter the discharge pipe 7, reducing the accumulation of residue at the end of the softening pot 2.

[0028] An inner sleeve 8 is provided at the axis of the softening pot 2. The liquid outlet end of the inner sleeve 8 is rotatably connected to the side wall of the softening pot 2 away from the feed port 5 through a bearing. A sub-bracket 9 is fixed to the outer wall of the softening pot 2 near the feed port 5. The liquid inlet end of the inner sleeve 8 is rotatably connected to the sub-bracket 9 through a bearing, and an elbow 801 is also fixed to the liquid inlet end of the inner sleeve 8. The heating medium hot water enters the inner sleeve 8 through the elbow 801 and circulates in the inner sleeve 8. The heat is conducted to the inner sleeve 8 and then transferred to the softening pot 2. The softening pot 2 is heated at the axis, which makes up for the problem that the softening pot 2 in the traditional technology lacks central heating and is only heated in the circumferential direction, resulting in a slow temperature rise rate inside the softening pot 2 and poor softening effect.

[0029] The liquid outlet end of the inner sleeve 8 passes through the softening pot 2 and is rotatably connected to a medium connecting head 10 through a sealed bearing. The medium connecting head 10 is hollow, and a circular hole 11 is provided at the center of the liquid outlet end of the inner sleeve 8. The diameter of the circular hole 11 is smaller than the inner diameter of the inner sleeve 8. The inner cavity of the inner sleeve 8 is connected to the medium connecting head 10 through the circular hole 11. A plurality of first conducting pipes 12 are fixed on the side wall of the medium connecting head 10 at equal angles around the axis of the inner sleeve 8. The other end of the first conducting pipe 12 is fixed to the jacket layer 3 and connected to the heating chamber 4. In this way, the hot water passing through the inner sleeve 8 then evenly enters the heating chamber 4 in the jacket layer 3 from the medium connecting head 10, and then flows through the heating chamber 4 to heat the softening pot 2 in the circumferential direction, thereby achieving the effect of simultaneous central heating and circumferential heating.

[0030] On the side wall of the jacket layer 3 near the feed port 5, a plurality of second conducting tubes 13 are fixed at equal angles around the jacket layer 3, and a connecting ring 14 is fixed at the other end of the plurality of second conducting tubes 13. The connecting ring 14 is located at the end of the softening pot 2 near the feed port 5. The inner cavity of the connecting ring 14 is connected with the heating cavity 4 through the second conducting tube 13. The heating medium that completes the heating work enters the second conducting tube 13 at the end of the jacket layer 3 and converges in the inner cavity of the connecting ring 14.

[0031] The inner cavity of the connecting ring 14 is open on the side away from the feed port 5. The inner wall of the open part of the connecting ring 14 is rotatably connected to a rotating plate 15 through a sealed bearing. A liquid outlet pipe 16 is fixed on the rotating plate 15. The heating medium gathered in the inner cavity of the connecting ring 14 is finally discharged through the liquid outlet pipe 16. The rotating setting of the rotating plate 15 and the connecting ring 14 avoids the motion interference between the liquid outlet pipe 16 and the softening pot 2, ensuring the normal rotation of the softening pot 2. During operation, the liquid inlet end of the pumping and heating device is connected to the liquid outlet pipe 16 to collect the heating medium, and the liquid outlet end of the pumping and heating device is connected to the elbow 801 to realize the circulation and heating effect of the heating medium. Similarly, the pumping and heating devices also adopt existing mature technologies, so they are not described here.

[0032] A bracket 17 is fixed to one end of the base 1 near the feed port 5, and a crossbeam 18 is fixed to the middle of the bracket 17. Both ends of the crossbeam 18 are connected to the rotating plate 15, and the rotating plate 15 is supported by the bracket 17. The top of the bracket 17 is also fixed to the end of the inner sleeve 8, and the end of the inner sleeve 8 is supported by the bracket 17, and the rotation of the inner sleeve 8 is limited to prevent it from rotating with the softening pot 2, so that the two can fully rotate relative to each other.

[0033] It should be noted that, when only the jacket layer 3 is heated in the traditional method, the medium temperature is slightly higher than the temperature required for soybean softening, by 2°C-10°C, because the raw materials are mostly in contact with the pot wall and the heat conduction path is short. In the present application, the heating medium is first heated at the center of the inner sleeve 8, and then passes through the first conducting pipe 12 to the jacket layer 3, where heat will be dissipated in the middle. Therefore, the medium temperature at the inlet of the inner sleeve 8 can be set to be 5°C-15°C higher than the softening temperature to compensate for the heat dissipation loss and ensure that the medium in the jacket layer 3 still reaches the softening temperature. At the same time, the soybeans are mostly located in the lower part of the pot body and have little contact with the inner sleeve 8, so the high temperature in the center will not cause overheating of the raw materials.

[0034] Two groups of nozzles 19 are fixed on the side wall of the inner sleeve 8. The two groups of nozzles 19 are arranged back to back. Each group of nozzles 19 is arranged at equal intervals along the axial direction of the inner sleeve 8, and the two groups of nozzles 19 are arranged at intervals. The liquid inlet end of the nozzle 19 extends into the inner cavity of the inner sleeve 8 and is fixed with a valve 20. The valve 20 has a handle 21 for operating the opening and closing of the valve 20. During the softening stage, the operating handle 21 closes the valve 20 to prevent the hot medium from being ejected from the nozzle 19, thereby ensuring that the hot medium passes through the inner sleeve 8 and completely enters the jacket layer 3 from the circular hole 11 at the end of the inner sleeve 8.

[0035] However, after the softening work is completed, when cleaning the inner wall of the softening pot 2, it is necessary to close the circular hole 11 and open the valve 20, so that hot water is sprayed from the nozzle 19 at high pressure to the inner wall of the softening pot 2 to clean the inner wall. At the same time, the softening pot 2 is driven to rotate to ensure that the inner wall of the softening pot 2 is cleaned in all directions. This high-pressure and high-temperature clean water is ejected at the axis of the softening pot 2, which can effectively avoid the dead angle problem and improve the cleaning efficiency and quality.

[0036] As for the opening of the valve 20 and the sealing of the circular hole 11, multiple support seats are fixed in parallel on the inner wall of the inner sleeve 8 along the axis of the inner sleeve 8, and a push rod 22 is slidably connected to the multiple support seats. The push rod 22 is located at the axis of the inner sleeve 8, and the cross-section of the push rod 22 in the length direction is square. A baffle 23 is fixed on the end of the push rod 22 close to the circular hole 11. The diameter of the baffle 23 is larger than the diameter of the circular hole 11 and smaller than the inner diameter of the inner sleeve 8. There is enough space between the outer periphery of the baffle 23 and the inner wall of the inner sleeve 8 for the circulation of heating medium. A sealing gasket 24 is fixed on the side of the baffle 23 close to the circular hole 11. When the communication path between the inner sleeve 8 and the heating chamber 4 is cut off, the push rod 22 is pushed so that the baffle 23 presses the sealing gasket 24 against the inner wall of the end of the inner sleeve 8 to seal the circular hole 11.

[0037] As for the opening and closing of the valve 20, the pushing action of the push rod 22 can be used to complete it synchronously. A driving rod 25 is provided on the outer wall of the push rod 22 opposite to each handle 21, and the length direction of the driving rod 25 is perpendicular to the length direction of the push rod 22. The rotation plane of the handle 21 is parallel to the outer wall of the push rod 22 on the side close to the handle 21. A pushing groove 26 is provided on the handle 21 along the length direction of the handle 21. The end of the driving rod 25 is inserted into the pushing groove 26. In the process of pushing the push rod 22 to block the circular hole 11, the push of the push rod 22 can synchronously drive the driving rod 25 to move, so that the handle 21 can be driven to rotate to open the valve 20, thereby achieving the effect of blocking the circular hole 11 and opening the valve 20.

[0038] As for the linear movement of the driving push rod 22, a screw 27 is rotatably connected to the side wall of the elbow 801 through a sealed bearing. The axis of the screw 27 coincides with the axis of the inner sleeve 8. A threaded sleeve 28 is fixed at the end of the push rod 22 close to the screw 27. The screw 27 is threadedly connected to the threaded sleeve 28. A handwheel 29 is fixed at the end of the screw 27 away from the threaded sleeve 28. By turning the handwheel 29, the screw 27 is driven to rotate, and the cooperation between the screw 27 and the threaded sleeve 28 is utilized to achieve the effect of pulling or pushing the push rod 22 to move.

[0039] In summary, the present invention forms "center-circumferential" dual heating by the inner sleeve 8 at the axis of the softening pot 2 and the outer jacket layer 3, thereby accelerating the heating speed and solving the problem of uneven heating; the inner sleeve 8 is provided with a high-pressure liquid spray structure, which can flush the inner wall in all directions in conjunction with the rotation of the pot body, avoiding the disadvantage of water accumulation in the lower part when the pot body is placed horizontally for cleaning, thereby improving the cleaning effect and efficiency. While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
