Description

Technical Field

[0001] The utility model relates to the technical field of grain peeling equipment, in particular to a vertical soybean peeling machine with a bearing cooling device. Background Art

[0002] At present, when soybean oil is produced, it is usually necessary to dehull the soybeans. This is because the soybean hulls contain very little oil, but contain a large amount of cellulose, pigment colloid and wax. If the soybeans are produced with the hulls on, not only will the hulls not produce oil, but they will absorb the oil and make the oil remain in the cake, making the color of the crude oil darker and the quality lower. The cake obtained by producing oil with the hulls on has a high hull content and a low protein content, which reduces the utilization value of the soybean meal. In addition, producing oil with the hulls on will also reduce the flaking effect and the quality of the flaked material, reduce the effective production capacity of the equipment, increase power consumption and cause wear of machine parts.

[0003] A vertical soybean peeling machine is a commonly used soybean peeling machine. It features a high-speed rotating lower friction disc and an upper friction disc within its housing. Soybeans enter the machine through the upper feed port, where they squeeze and rub the soybeans together to peel them. The lower friction disc is mounted on the upper end of a main shaft, which is connected to the housing via upper and lower bearing assemblies. The rotation of the main shaft drives the lower friction disc to rotate at high speed. However, the lower friction disc generates a significant amount of frictional heat during soybean peeling. A small amount of this heat is dissipated with the soybeans, while the majority accumulates on the lower friction disc, raising its temperature. Simultaneously, this heat is transferred along the main shaft to the upper bearing assembly, located below the lower friction disc. The upper bearing assembly also generates heat during operation. The combined heat from these two components causes the bearing to heat up rapidly and reduces the viscosity of the bearing lubricant, seriously impacting the bearing lubricant and its service life. For the lower bearing assembly, the lower bearing assembly is located at the lower part of the main shaft. It needs to bear the weight of the main shaft and the lower friction plate, as well as the weight of the material falling on the lower friction plate. The lower bearing assembly also has the problem of rapid bearing heating. Utility Model Content

[0004] In view of this, in order to overcome the shortcomings of the existing technical problems, the utility model provides a vertical soybean peeling machine with a bearing cooling device. Blades are installed on the main shaft of the vertical soybean peeling machine. The blades rotate with the main shaft to generate airflow blowing towards the bearing assembly. The flowing airflow is used to accelerate the heat dissipation of the bearing assembly, thereby realizing cooling of the bearing assembly, ensuring the service life of the bearing assembly, ensuring the stable operation of the vertical soybean peeling machine, and reducing its repair and maintenance costs.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is as follows:

[0006] A vertical soybean peeling machine with a bearing cooling device, which includes a shell and a main shaft rotating relative to the shell. The upper part of the main shaft is connected to the shell for relative rotation through an upper bearing assembly, and the lower part of the main shaft is connected to the shell for relative rotation through a lower bearing assembly. Bearing cooling devices are provided on the main shafts above the upper bearing assembly and above the lower bearing assembly. The bearing cooling devices can rotate with the main shaft. The bearing cooling devices include at least two blades, which are fixedly connected to the main shaft and are evenly arranged along the circumference of the main shaft. The blades rotate under the drive of the main shaft to generate an airflow blowing toward the upper bearing assembly or the lower bearing assembly.

[0007] Furthermore, the bearing cooling device further comprises a connecting sleeve, which is sleeved on the main shaft and fixedly connected to the main shaft. The blades are connected to the connecting sleeve and are evenly arranged along the circumference of the connecting sleeve.

[0008] Furthermore, the connecting sleeve is connected to the main shaft through a top screw; or the connecting sleeve is connected to the main shaft through a tightening sleeve; or the main shaft is provided with threaded holes arranged along the radial direction of the main shaft, and the connecting sleeve is fastened to the main shaft through bolts threaded in the threaded holes.

[0009] Furthermore, the upper end of the shell is connected to a feeding device, and the feeding device has a conical cover shell with a feed port on the cover shell. A conical upper friction cover is provided on the inner wall of the cover shell, and a lower friction cover with a conical structure is provided on the upper end of the main shaft. The lower friction cover is connected to the power device through the main shaft, and the feed port corresponds to the lower friction cover. The lower friction cover is located in the conical cavity of the upper friction cover, and a material peeling channel is formed between the top surface of the lower friction cover and the inner wall of the upper friction cover. The bearing cooling device above the upper bearing assembly is arranged between the upper bearing assembly and the conical lower friction cover, and is located in the conical cavity of the lower friction cover.

[0010] Furthermore, a funnel-shaped receiving hopper is provided in the shell, the receiving hopper is located below the upper bearing assembly, and the upper end opening of the receiving hopper is fixedly connected to the inner wall of the shell, and the lower end opening of the receiving hopper discharges material through the discharge channel, and the bearing cooling device above the lower bearing assembly is located on the main shaft between the receiving hopper and the lower bearing assembly.

[0011] The beneficial effects of the utility model are:

[0012] 1. The main shaft of the vertical soybean peeling machine of the utility model is equipped with blades. The blades rotate with the main shaft to generate airflow blowing towards the bearing assembly. The flowing airflow is used to accelerate the heat dissipation of the bearing assembly, thereby realizing the cooling of the bearing assembly, ensuring the service life of the bearing assembly, ensuring the stable operation of the vertical soybean peeling machine, and reducing its repair and maintenance costs.

[0013] 2. The blades of the present invention are connected to the main shaft through a connecting sleeve. The blades are first installed on the connecting sleeve, and then the connecting sleeve is put on the main shaft, thereby facilitating the rapid installation and connection of the blades and the main shaft.

[0014] 3. The bearing cooling device above the upper bearing assembly of the utility model is arranged between the upper bearing assembly and the lower friction cover, and is located in the conical cavity of the lower friction cover. The material entering from the feed port moves along the material peeling channel between the lower friction cover and the upper friction cover, and the bearing cooling device is located in the conical cavity of the lower friction cover. With this structure, when the blades of the bearing cooling device rotate with the main shaft, the conical structure of the lower friction cover forms a cover-like protection for the bearing cooling device, which can reduce the material being sucked into the airflow generated by the rotating blades, and reduce the material being blown to the upper bearing assembly by the blades.

[0015] 4. The lower friction cover of the utility model adopts a conical structure. The material entering from the feed port is directly dispersed by the conical lower friction cover, and the material flows downward along the conical surface of the lower friction cover. This structure can effectively reduce the residence time of the material in the lower friction cover and reduce the impact of the material weight on the bearing assembly.

[0016] 5. The shell of the utility model is provided with a funnel-shaped receiving hopper. The material after friction peeling between the lower friction cover and the upper friction cover falls into the receiving hopper along the material peeling channel, and then is discharged from the shell through the discharge channel at the lower end of the receiving hopper. The bearing cooling device for cooling the lower bearing assembly is located on the main shaft between the lower bearing assembly and the receiving hopper, which can effectively avoid the influence of the material on the bearing cooling device.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings and embodiments:

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, a vertical soybean peeling machine with a bearing cooling device includes a shell 1, the upper end of the shell 1 is connected to a feeding device, the feeding device has a conical cover 2, the cover 2 has a feeding port 3, and the inner wall of the cover 2 is provided with a conical upper friction cover 4. A main shaft 5 that can rotate relative to the shell 1 is provided in the shell 1, the main shaft 5 is connected to a power device 6, and the power device 6 provides power and transmission for the rotation of the main shaft 5. A conical lower friction cover 7 is provided on the upper end of the main shaft 5, and the feeding port 3 corresponds to the lower friction cover 7. The lower friction cover 7 is located in the conical cavity of the upper friction cover 4. A material peeling channel 8 is formed between the top surface of the lower friction cover 7 and the inner wall of the upper friction cover 4. The upper portion of the main shaft 5 is connected to the housing 1 for relative rotation via the upper bearing assembly 9, and the lower portion of the main shaft 5 is connected to the housing 1 for relative rotation via the lower bearing assembly 10. A funnel-shaped material receiving hopper 11 is provided in the housing 1. The material receiving hopper 11 is located below the upper bearing assembly 9, and the upper end opening of the material receiving hopper 11 is fixedly connected to the inner wall of the housing 1. The lower end opening of the material receiving hopper 11 discharges material through a discharge channel 12. An upper bearing cooling device 13 is provided on the main shaft 5 above the upper bearing assembly 9. The upper bearing cooling device 13 is disposed between the upper bearing assembly 9 and the lower friction cover 7 and is located in the conical cavity of the lower friction cover 7. A lower bearing cooling device 14 is provided on the main shaft 5 above the lower bearing assembly 10. The lower bearing cooling device 14 is located on the main shaft 5 between the material receiving hopper 11 and the lower bearing assembly 10. The upper bearing cooling device 13 and the lower bearing cooling device 14 have the same structure, both including a connecting sleeve 15 and at least two blades 16. The number of blades 16 is preferably 4. The blades 16 are welded and fixed on the outer circumference of the connecting sleeve 15, and the blades 16 are evenly arranged along the circumference of the connecting sleeve 15. The connecting sleeve 15 is sleeved on the main shaft 5 and is relatively fixedly connected to the main shaft 5 by a top screw. When the main shaft 5 rotates under the drive of the power device 6, the connecting sleeve 15 and the blades 16 rotate with the main shaft 5, generating an airflow blowing toward the upper bearing assembly 9 or the lower bearing assembly 10, thereby cooling the upper bearing assembly 9 and the lower bearing assembly 10.

[0024] In this embodiment, the connecting sleeve 15 is a metal sleeve with a length of 30 mm and a wall thickness of 8 mm. The blades 16 are flat strip-shaped blades 16 with a length of 30 mm, a thickness of 4 mm, and a width of 20 mm. The blades 16 are welded vertically to the fixing sleeve, with an angle of 0 to 45° with the horizontal. Of course, in actual production, the blades 16 can also be made into a fan blade shape to better generate airflow toward the bearing assembly.

[0025] Taking soybean peeling as an example, when in use, the power device 6 is started, and the power device 6 drives the main shaft 5 to rotate, thereby rotating the lower friction cover 7 and the blades 16 on the main shaft 5, and the soybean material enters the shell 1 from the feed port 3 at the upper end of the shell 1. Since the feed port 3 corresponds to the lower friction cover 7, under the action of the conical lower friction cover 7, the soybean material is dispersed and flows downward along the conical surface of the lower friction cover 7, and enters the material peeling channel 8 between the upper friction cover 4 and the lower friction cover 7. The lower friction cover 7 rotates driven by the main shaft 5, squeezes and rubs the soybean material during the rotation, grinds the surface of the soybean material, and thus peels the soybean material. After peeling, the soybean hulls and bean kernels fall into the receiving hopper 11. The funnel-shaped receiving hopper 11 re-gathers the scattered soybean materials and discharges them from the discharge channel 12. The peeling of the soybean material is completed. During the peeling process, the main shaft 5 drives the connecting sleeve 15 and the blade 16 to rotate. The blade 16 generates airflow during the rotation. The airflow generated by the bearing cooling device above the upper bearing assembly 9 blows toward the upper bearing assembly 9 to cool the upper bearing assembly 9. The airflow generated by the bearing cooling device above the lower bearing assembly 10 blows toward the lower bearing assembly 10 to cool the lower bearing assembly 10. This can effectively prevent the upper bearing assembly 9 and the lower bearing assembly 10 from being overheated, and avoid damage to the upper bearing assembly 9 and the lower bearing assembly 10 caused by overtemperature, thereby ensuring the service life of the upper bearing assembly 9 and the lower bearing assembly 10, reducing the frequency of shutdown and maintenance of the vertical soybean peeling machine, and reducing maintenance costs.

[0026] In addition, the connecting sleeve 15 of the present invention can also be connected to the main shaft 5 by a expansion sleeve, which can reduce damage to the main shaft 5. In addition, the present invention can also provide threaded holes arranged along the radial direction of the main shaft 5 on the main shaft 5, and the connecting sleeve 15 is fastened to the main shaft 5 by bolts threaded into the threaded holes.

[0027] It should be noted that the above embodiments are illustrative of the technical solutions of the present invention rather than limiting. Equivalent substitutions or other modifications made by ordinary technicians in the relevant technical field based on the existing technology should be included in the scope of rights required by the present invention as long as they do not exceed the concept and scope of the technical solutions of the present invention.
