Description

Technical Field

[0001] The present invention relates to the technical field of pulp crushing and processing, and specifically relates to a pulp crushing device and method with pretreatment. Background Art

[0002] Fruit ice cream is a new type of ice cream made by adding various fresh fruit juices to ice cream. When processing fruit pulp, the peeled fruit needs to be broken and filtered through a sieve to form a pulp sauce, thereby obtaining pure fruit juice and retaining the nutrients in the juice, so as to improve the quality and taste of fruit ice cream.

[0003] The existing authorized publication number is: CN116921031B, which discloses a pulp crushing and filtering device for fruit juice beverage processing. The outer surface of the inner pressure relief chamber of this device is fixedly connected to the top of the inner surface of the cylinder body. The top of the inner pressure relief chamber is fixedly connected with a top shell, and a feeding port is opened on the upper surface of the top shell; the pulp enters from the feeding port and discharges from the pulp discharge port and the fruit juice discharge port respectively, achieving the effect of separating the pulp from the fruit juice. However, when the above device is used, during the process of crushing the pulp, large-particle pulp will accumulate at the bottom of the tank body. The chopped large-particle pulp still contains a lot of fruit juice, resulting in the problem that the fresh pulp is not crushed thoroughly due to the accumulation of large particles at the bottom of the tank body. And the above device directly separates the pulp, so if you want to obtain the fruit juice inside the pulp, you need to perform secondary processing on the filtered pulp, which is rather cumbersome.

[0004] Based on this, a pulp crushing device and method with pretreatment are now provided, which can eliminate the drawbacks of the existing device. Summary of the Invention

The sorting mechanism facilitates screening the pulp inside the main box body 11 and crushing the screened pulp. One end of the transmission pipe 24 is symmetrically provided with connecting rods, and the other ends of the connecting rods are fixedly connected to the rotating disk. The rotating disk is rotatably arranged in the limiting groove at the inner bottom end of the main box body 11. One end of the fixed shaft 28 is rotatably arranged in the limiting hole at the upper end of the rotating disk. One end of the sleeve shaft is fixedly provided with a first bevel gear, and a second bevel gear is meshed with the first bevel gear. The second bevel gear is fixedly arranged on the output end of the third motor 26. The third motor 26 is fixedly arranged at the upper end of the main box body 11. One end of the fixed shaft 28 is fixedly provided with a third gear 30, and a fourth gear is meshed with the third gear 30. The fourth gear is fixedly arranged on the output end of the fourth motor 31. The fourth motor 31 is fixedly arranged at the upper end of the main box body 11. The bottom end of the main box body 11 is communicated with a discharge pipe 12, and a valve is arranged on the discharge pipe 12. During use, when processing the pulp inside the main box body 11, the third motor 26 and the fourth motor 31 are started. The third motor 26 drives the transmission pipe 24 to rotate through the meshing of the second bevel gear and the first bevel gear, and the fourth motor 31 drives the fixed shaft 28 to rotate through the meshing of the fourth bevel gear and the third gear 30.

A seventh gear 36 is fixedly arranged on the rotating pipe. A sixth gear is meshed with the seventh gear 36. The sixth gear is fixedly arranged at one end of the transmission shaft. A fixed pipe is rotatably arranged on the transmission shaft. The fixed pipe is fixedly arranged at the upper end of the main box body 11. The other end of the transmission shaft is fixedly provided with a fifth gear. The fifth gear is meshed with the third gear 30. During use, when the sleeve shaft drives the transmission pipe 24 to rotate, the sleeve shaft drives the two scraping frames 38 to rotate. The scraping frame 38 drives the third mounting shaft 39 to rotate. At the same time, the third gear 30 drives the rotating pipe to rotate through the transmission shaft. The rotating pipe drives the second toothed ring 35 to rotate. Thus, the second toothed ring 35 drives the third mounting shaft 39 to rotate around its own axis while revolving through the eighth gear. The protective cover 37 crushes the pulp inside the main box body 11 through a number of third crushing knives 40.

[0028] The preprocessing mechanism includes a first mounting shaft 18. The first mounting shaft 18 is rotatably provided in each of several material distribution grooves. A number of first crushing knives 19 are evenly spaced on the first mounting shaft 18. One end of the material distribution roller 16 is fixedly connected to the output end of the first motor 17. The first motor 17 is fixedly arranged on the transfer pipe 14. One end of each first mounting shaft 18 is fixedly provided with a first gear. A number of the first gears are all meshed with a first toothed ring 20. The outer side of the first toothed ring 20 is provided with a number of external teeth. One side of the first toothed ring 20 is fixedly provided with a number of support frames. The other ends of a number of the support frames are all fixedly connected to the outer ring of a bearing 22. The inner ring of the bearing 22 is fixedly provided with a support pipe. One end of the support pipe is fixedly arranged on one side of a support plate. The support plate is fixedly arranged on the upper end of the main box body 11. The rotating shaft at the other end of the material distribution roller 16 is rotatably arranged in a rotating hole on one side of the support plate. A second gear is meshed with the outer side of the first toothed ring 20. The second gear is fixedly arranged at the output end of a second motor 21. The second motor 21 is fixedly arranged on one side of the support plate. When in use, when it is necessary to crush the pulp, the processed pulp is placed inside the storage box 15. Subsequently, the first motor 17 is controlled to start through an external control component. The first motor 17 drives the material distribution roller 16 to rotate intermittently, rotating 90 degrees each time, so that a material distribution groove on the material distribution roller 16 is aligned with the bottom end of the storage box 15. At the same time, the output end of the second motor 21 drives the first toothed ring 20 to rotate through the second gear. The first toothed ring 20 drives a number of first mounting shafts 18 to rotate through a number of first gears, so that the pulp falls into the material distribution groove. After the material distribution groove rotates again, the material distribution groove is in a closed state. The first mounting shaft 18 can initially crush the pulp through a number of first crushing knives 19. When the material distribution groove rotates to the upper end of the feed pipe 13, the pulp inside the material distribution groove falls into the main box body 11.

[0029] A baffle frame 23 is fixedly arranged at the upper end inside the main box body 11. The baffle frame 23 is aligned with the discharge end of the feed pipe 13. Limit plates are fixedly arranged on both sides of the transfer pipe 14. The limit plates are fixedly arranged on the upper end of the main box body 11. When in use, the baffle frame 23 can prevent the pulp falling from the discharge end of the feed pipe 13 from splashing, and the limit plates can support and fix the transfer pipe 14.

[0030] The sorting mechanism includes a material distributing plate 29. A plurality of material distributing plates 29 are fixedly arranged on the fixed shaft 28 at positions corresponding to the inside of the screening box 25. The material distributing plates 29 are in close contact with the inside of the screening box 25. A plurality of mounting holes are provided at the bottom end and the side of the fixed shaft 28, and first filter plates are arranged in the mounting holes. Discharge ports are symmetrically arranged on the screening box 25, and communicating pipes are connected to the discharge ports. One end of each communicating pipe is connected to a crushing box 32. A second filter plate is fixedly arranged at the bottom end of the crushing box 32. Second mounting shafts 33 are rotatably arranged inside the crushing boxes 32. A plurality of second crushing knives 34 are equidistantly arranged on the second mounting shafts 33. A ninth gear is fixedly arranged at one end of each second mounting shaft 33, and the ninth gears are all meshed with a second toothed ring 35. A protective cover 37 is arranged in cooperation with the second toothed ring 35. The protective cover 37 is arranged in cooperation with the second mounting shafts 33 and the third mounting shafts 39. During use, when the spiral plate 27 and the transmission pipe 24 cooperate to convey the pulp and juice at the bottom end of the main box body 11 into the screening box 25, since the screening box 25 is in a rotating state, under the action of centrifugal force, the juice can be filtered out. At the same time, the qualified fruit grains fall through the first filter plate, and the pulp with a larger volume is intercepted by the first filter plate and adheres to the side of the screening box 25 under the action of centrifugal force. At this time, the fixed shaft 28 drives the material distributing plate 29 to rotate, so that the material distributing plate 29 scrapes the pulp adhering to the inside of the screening box 25. When the material distributing plate 29 drives the pulp to rotate to one end of the communicating pipe, the pulp falls into the crushing box 32. When the crushing box 32 rotates following the sleeve shaft, the ninth gear is meshed with the second toothed ring 35, so that the second mounting shaft 33 rotates around its own axis while revolving. The second mounting shaft 33 further crushes the pulp through a plurality of second crushing knives 34, and the crushed fruit grains and juice fall into the main box body 11 through the second filter plate. Embodiment 2

[0031] The difference from Embodiment 1 is that scraping plates 41 are fixedly arranged on the connecting rods. The scraping plates 41 are arranged obliquely and are in close contact with the bottom end inside the main box body 11. A plurality of mixing plates are fixedly arranged at one end of the transmission pipe 24. During use, when the transmission pipe 24 rotates, the transmission pipe 24 drives the scraping plates 41 and the mixing plates to rotate, so that the pulp deposited at the bottom of the main box body 11 floats, and then the pulp is conveyed into the screening box 25 for processing through the cooperation of the transmission pipe 24 and the spiral plate 27.

[0032] The above embodiments disclose a pulp crushing device with pretreatment. When it is necessary to crush the pulp, the processed pulp is placed inside the storage bin 15. Subsequently, the first motor 17 is controlled to start by an external control component. The first motor 17 drives the material distribution roller 16 to rotate intermittently, rotating 90 degrees each time, so that a material distribution groove on the material distribution roller 16 is aligned with the bottom end of the storage bin 15. At the same time, the output end of the second motor 21 drives the first toothed ring 20 to rotate through the second gear. The first toothed ring 20 drives several first mounting shafts 18 to rotate through several first gears, so that the pulp falls into the material distribution groove. After the material distribution groove rotates again, the material distribution groove is in a closed state. The first mounting shaft 18 can initially crush the pulp through several first crushing knives 19. When the material distribution groove rotates to the upper end of the feed pipe 13, the pulp inside the material distribution groove falls into the main box body 11; Start the third motor 26 and the fourth motor 31. The third motor 26 drives the sleeve shaft to rotate through the engagement of the second bevel gear and the first bevel gear. The sleeve shaft drives two scraping frames 38 to rotate. The scraping frames 38 drive the third mounting shaft 39 to rotate. At the same time, the third gear 30 drives the rotating pipe to rotate through the transmission shaft. The rotating pipe drives the second toothed ring 35 to rotate. Thus, the second toothed ring 35 drives the third mounting shaft 39 to rotate around its own axis while revolving through the eighth gear. The protective cover 37 crushes the pulp inside the main box body 11 through several third crushing knives 40. The fourth motor 31 drives the fixed shaft 28 to rotate through the engagement of the fourth bevel gear and the third gear 30. The fixed shaft 28 rotates the spiral plate 27, so that the pulp and juice inside the main box body 11 enter the inside of the transmission pipe 24 from the bottom end of the transmission pipe 24. Subsequently, under the action of the spiral plate 27, the pulp and juice are conveyed, and are discharged into the screening box 25 through the other end of the transmission pipe 24. At the same time, when the transmission pipe 24 rotates, the transmission pipe 24 drives the scraper 41 and the mixing plate to rotate, so that the pulp deposited at the bottom of the main box body 11 floats, and then the pulp is conveyed into the screening box 25 through the cooperation of the transmission pipe 24 and the spiral plate 27 for processing; Since the screening box 25 is in a rotating state, under the action of centrifugal force, the juice can be filtered out. At the same time, the qualified fruit grains fall through the first filter plate, and the larger-volume pulp is intercepted by the first filter plate and adheres to the side of the screening box 25 under the action of centrifugal force. At this time, the fixed shaft 28 drives the dialing plate 29 to rotate, so that the dialing plate 29 scrapes the pulp adhering to the inside of the screening box 25. When the dialing plate 29 drives the pulp to rotate to one end of the communicating pipe, the pulp falls into the crushing box 32. When the crushing box 32 rotates following the sleeve shaft, the ninth gear meshes with the second toothed ring 35, so that the second mounting shaft 33 rotates around its own axis while revolving. The second mounting shaft 33 further crushes the pulp through several second crushing knives 34. The crushed fruit grains and juice fall into the main box body 11 through the second filter plate.

[0033] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
