Description

Technical Field

[0001] This utility model belongs to the field of rapeseed oil production and processing technology, specifically, it relates to an automatic crushing and recycling device for pressed cake. Background Technology

[0002] In the production and processing of rapeseed oil, a large amount of pressed cake is generated after the pressing process. These pressed cakes usually contain a certain amount of residual oil and other usable components. Reasonable crushing and recycling can not only improve resource utilization and reduce production costs, but also conform to the concept of green production.

[0003] The prior art discloses a tea oil pressing and recycling device (CN221693779U), which includes a crushing tank. A shell is fixedly connected to the upper surface of the crushing tank and is connected to the crushing tank. A crushing assembly is provided on the inner wall of the shell. The crushing assembly includes a first rotating shaft, crushing rollers, gears and a first motor. The crushing assembly is also provided on the inner wall of the crushing tank. The crushing assembly includes a fixed frame, a second rotating shaft, multiple crushing blades, multiple scrapers and a second motor. A screening plate is fixedly connected to the inner wall of the crushing tank. By setting the crushing assembly, the hard tea oil cake is crushed into small pieces under the action of two crushing rollers, which is convenient for subsequent crushing. By setting the crushing assembly, the second rotating shaft drives multiple crushing blades to rotate, thereby crushing the fallen tea oil cake small pieces into powder. The screening plate is used to screen the powder.

[0004] The search revealed that existing technologies cannot adapt to crushing processes with different particle requirements, resulting in relatively limited application effects. This makes the equipment unable to meet the diverse needs of rapeseed cake recovery. Furthermore, during the crushing process, residues tend to accumulate on the surface of the screening plate, causing blockages, which not only affects cleaning but also reduces the screening efficiency of the equipment.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] An automatic crushing and recycling device for press cake, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0030] The box body 10 has a top cover 11 hinged to the top of the box body 10, a side door 12 hinged to one side of the box body 10, and three discharge ports 13 fixedly provided on the other side of the box body 10.

[0031] The grading and crushing assembly is rotatably disposed within the housing 10. The grading and crushing assembly includes a crushing roller 30, an air duct crushing roller 31, a crushing blade 34, and a grinding roller 35. There are two crushing rollers 30. Both crushing rollers 30, the crushing blade 34, and the grinding roller 35 are rotatably disposed within the housing 10. The air duct crushing roller 31 is fixedly disposed within the housing 10.

[0032] The wind power assembly is installed inside the housing 10. The wind power assembly includes an air supply pipe 16, an air conveying pipe 29, an air inlet duct 32, and a spiral fan 33. Three air conveying pipes 29 are arranged in an array on the air supply pipe 16, and all three air conveying pipes 29 are connected to the air supply pipe 16. The air inlet duct 32 is fixedly installed at one end of the air duct crushing roller 31, and the spiral fan 33 is rotatably installed inside the air inlet duct 32. The air supply pipe 16 is connected to the air duct crushing roller 31 through the air inlet duct 32.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the box 10 is provided with a feed inlet 14, which is set in relation to the top cover 11. A back compartment 15 is provided on one side of the box 10, which is set in relation to the side door 12. Two screening plates 25 are fixedly installed inside the box 10. A discharge slope 27 is fixedly installed on the bottom surface of the box 10. Each of the two screening plates 25 and the discharge slope 27 is provided with a discharge outlet 13.

[0034] Specifically, the crushing roller 30 and the pulverizing blade 34 each correspond to a screening plate 25. The screening apertures of the two screening plates 25 and the grinding screen plate 26 are different. The screening apertures of the screening plates 25 corresponding to the two crushing rollers 30 and the air-blast crushing roller 31 are larger, suitable for the initial crushing needs. At the same time, the particle size of the material discharged here is suitable for feed additives. Moving downwards, the screening apertures of the screening plates 25 corresponding to the crushing roller 30 are relatively smaller. The particle size of the material discharged here is suitable for secondary leaching for oil extraction. The grinding roller 35 corresponds to the grinding screen plate 26, and the screening apertures at the grinding screen plate 26 are smaller. The output material is relatively fine, suitable for the special needs of ultra-fine grinding. Different methods are used to crush the rapeseed cake to different degrees, so that different particle sizes can be obtained to meet different recycling needs. This makes the device have good usability and applicability. When in use, open the top cover 11 and put the rapeseed oil cake into the feed inlet 14. The grading and crushing component crushes the cake to different degrees. Then, the cake of different particle sizes flows through the screening plates 25 of different specifications and flows into the corresponding discharge outlet 13 for discharge. Finally, the powder material that is too fine flows out through the guide of the discharge slope 27.

[0035] like Figure 2 , Figure 3 and Figure 5 As shown, an air compressor 17 is fixedly installed at the bottom of the back chamber 15. The output end of the air compressor 17 is connected to the bottom of the air supply pipe 16. Three air ducts 24 are arrayed on the inner wall of the box 10. The three air ducts 24 are respectively set to two screening plates 25 and a discharge slope 27. The three air ducts 24 are respectively set to different air supply pipes 29.

[0036] The working principle is as follows: the input end of the air compressor 17 is connected to the outside air, and the compressed air inside is delivered to the crushing roller 31 of the air duct through the air supply pipe 16. The compressed air drives the rotation of the spiral fan 33, and the spiral fan 33 drives the airflow to form a vortex. The vortex air passes through the crushing roller 31 of the air duct to dry the initially crushed press cake, reducing the possibility of oil leakage caused by internal moisture and thus reducing the burden of cleaning. At the same time, the compressed air blows the air into the air duct 24 through the three air supply pipes 29. The air duct 24 corresponds to the inclined position of the screening plate 25, which blows the crushed material on the screening plate 25 and prevents the screening plate 25 from clogging to a certain extent.

[0037] like Figure 2 and Figure 5 As shown, a gear 20 is fixedly installed at one end of each of the two crushing rollers 30. The two gears 20 mesh with each other and are rotatably mounted on the back chamber 15. The two crushing rollers 30 and the air duct crushing roller 31 are staggered and grind against each other.

[0038] The working principle is as follows: the two crushing rollers 30 and the air duct crushing roller 31 are staggered and grind each other. The air duct crushing roller 31 is fixedly installed in the housing 10. The two gears 20 drive their respective crushing rollers 30 to grind and rotate below the air duct crushing roller 31, continuously squeezing and crushing the press cake. The air duct crushing roller 31 is located above the two crushing rollers 30 and can blow dry the crushed press cake below.

[0039] like Figure 2 and Figure 5 As shown, a double-groove pulley 22 is fixedly installed at one end of the crushing blade 34, and a single-groove pulley 23 is fixedly installed at one end of the grinding roller 35. There are two single-groove pulleys 23. Another single-groove pulley 23 is fixedly installed on one side of one of the gears 20. A belt 21 is provided between the single-groove pulley 23 on the side of the gear 20 and the double-groove pulley 22. There are two belts 21. Another belt 21 is provided between the single-groove pulley 23 on the side of the grinding roller 35 and the double-groove pulley 22.

[0040] like Figure 2 and Figure 5 As shown, a bracket 18 is fixedly installed on one side of the back chamber 15, and a motor 19 is fixedly installed on the bracket 18. The output end of the motor 19 is connected to the single groove pulley 23 on the side of the grinding roller 35.

[0041] The working principle is as follows: Open the side door 12 and start the motor 19 in the back chamber 15. The motor 19 drives the single groove pulley 23 connected to the grinding roller 35 to rotate. The single groove pulley 23 drives the double groove pulley 22 above to rotate through the corresponding belt 21. The double groove pulley 22 drives the crushing blade 34 to rotate. At the same time, the double groove pulley 22 drives the single groove pulley 23 connected to the gear 20 above to rotate through another corresponding belt 21. The gear 20 rotates and meshes with another adjacent gear 20. At this time, the two crushing rollers 30 grind and rotate.

[0042] like Figure 4 and Figure 5 As shown, semi-circular guide blocks 28 are symmetrically fixed on the inner wall of the box 10. The crushing blade 34 is rotatably set between the two guide blocks 28. An arc-shaped grinding screen plate 26 is fixedly set inside the box 10. The grinding screen plate 26 is located above the discharge slope 27. The grinding roller 35 is attached to and rolls on the curved surface of the grinding screen plate 26.

[0043] The working principle is as follows: Pressed cake is added through the feed inlet 14. After initial crushing by the two crushing rollers 30, larger particles remain on the surface of the upper screen plate 25 and are then blown out by compressed air to the corresponding discharge port 13. Cakes of suitable size fall from the curved surface of the two guide blocks 28 through the screening of the upper screen plate 25 and are further crushed in the crushing range of the crushing blade 34. The crushed cakes are then screened by the bottom screen plate 25. The cakes remaining on the bottom screen plate 25 are blown out by compressed air, and cakes of suitable particle size fall onto the grinding screen plate 26. The grinding rollers 35 and the grinding screen plate 26 continuously grind the cakes. When the pressed cakes are pulverized, they fall onto the discharge slope 27 through the grinding screen plate 26 and are then blown out by compressed air. It should be noted that the powder ground by the grinding rollers 35 is too fine. When collecting, the corresponding discharge port 13 needs to be wrapped with a collection bag to prevent the overly dry powder from scattering outside the box 10 and causing waste.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
