[0026] 1. In the present invention, a centrifugal mechanism is provided inside the pulp crushing device.

[0028] 3. In the present invention, a guide plate is installed at the discharge port of the filter press box. When the filter press assembly filters the crushed pulp, the guide plate is vertically arranged in the discharge port to seal the discharge port and prevent the crushed pulp from splashing out during the filtration process, ensuring the normal progress of the filtration process. When the discharge assembly pushes and discharges the crushed pulp after filtration is completed, the discharge assembly can synchronously drive the guide plate to rotate and move, so that the guide plate is inclined downward on one side of the discharge port, thereby guiding and transporting the crushed pulp during discharge and making the discharge process more convenient.

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

[0041] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationships are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the invention.

[0042] Please refer to Figure 1 , Figure 8 As shown, the present invention is a fresh - squeezed pulp micro - crushing device, which includes a frame 1 and a cylinder 2 installed on the top of the frame 1. A crushing mechanism 3 and a centrifugal mechanism 4 are installed inside the cylinder 2; the crushing mechanism 3 includes a feeding component and a crushing component. The feeding component is used to convey the pulp into the interior of the cylinder 2, and the crushing component is used to shear - crush the pulp conveyed into the interior of the cylinder 2; and when the crushing component shear - crushes the pulp, it can drive the centrifugal mechanism 4 to rotate in the opposite direction relative to the crushing component, so that the centrifugal mechanism 4 can centrifugally separate the crushed pulp into juice and solid residues; a discharging mechanism 5 is installed at the bottom end of the cylinder 2, and the discharging mechanism 5 includes a liquid - discharging component, a pressure - filtering component and a discharging component; the liquid - discharging component can collect the centrifugally separated juice and discharge the juice to the outside of the cylinder 2, the pressure - filtering component can pressure - filter the centrifugally separated solid residues and convey the pressure - filtered separated juice into the liquid - discharging component, and the discharging component can discharge the pressure - filtered solid residues to the outside of the cylinder 2;

[0043] Specifically, when the crushing device is in use, the pulp is conveyed into the centrifugal mechanism 4 inside the cylinder 2 through the feeding component, and then the pulp is shear - crushed by the crushing component. At the same time, the crushing component drives the centrifugal mechanism 4 to rotate in the opposite direction, so that the centrifugal mechanism 4 centrifugally separates the crushed pulp. At this time, the juice in the crushed pulp is separated and conveyed into the liquid - discharging component, collected and discharged by the liquid - discharging component. Then, the remaining solid residues after separation are conveyed into the pressure - filtering component, the pressure - filtering component pressure - filters the solid residues and conveys the pressure - filtered separated juice into the liquid - discharging component. Finally, the pressure - filtered solid residues are discharged to the outside of the cylinder 2 through the discharging component;

[0044] In this embodiment, the separation rate of juice in the crushed pulp can be improved by centrifugal separation, thereby improving the pulp juicing rate and preventing juice waste; and the crushing component can drive the centrifugal mechanism 4 to rotate in the opposite direction relative to the crushing component when shearing and crushing the pulp, so that the centrifugal mechanism 4 can work synchronously with the crushing component, making the driving and use process of the centrifugal mechanism 4 more convenient. At the same time, since the centrifugal mechanism 4 rotates in the opposite direction to the crushing component, the centrifugal mechanism 4 can drive the pulp to rotate in the opposite direction relative to the crushing component, thereby increasing the relative shear collision speed between the crushing component and the pulp. Thereby improving the crushing efficiency and crushing effect of the crushing component on the pulp; the residue produced after the centrifugal separation of the crushed pulp is again subjected to filter pressing separation by the filter pressing component to further separate and precipitate the juice in the crushed pulp, thereby further improving the separation rate of the juice in the crushed pulp and the juice extraction rate of the pulp; and the solid residue after the filter pressing can be discharged to the outside of the cylinder 2 through the unloading component, so that the crushing, centrifugal separation, filter pressing and unloading of the pulp can be continuously performed through the cooperation of the crushing component, the centrifugal mechanism 4, the filter pressing component and the unloading component, which can improve the efficiency of the pulp crushing and separation.

[0045] See also Figures 1 - 3 As shown, in one embodiment, the crushing assembly includes a crushing motor 31 and a crushing shaft 34. The crushing motor 31 is fixedly mounted at the lower end of the frame 1, and the crushing shaft 34 is rotatably mounted inside the cylinder 2. A plurality of groups of equally spaced crushing blades 36 are fixedly mounted on the outer ring of the crushing shaft 34. The crushing motor 31 and the crushing shaft 34 are connected by a transmission through a reducer 33.

[0046] The feed assembly includes a feed hopper 32, which is fixedly mounted at one end of the cylinder 2, and one side of the lower end of the feed hopper 32 is connected to the inside of the cylinder 2, a crushing shaft 34 passes through the feed hopper 32, and a spiral auger 35 located inside the feed hopper 32 is fixedly mounted on the outer ring of the crushing shaft 34;

[0047] When the crushing mechanism 3 is working, the pulp is first put into the feed hopper 32, and then the crushing motor 31 is turned on. The crushing motor 31 drives the crushing shaft 34 to rotate after being reduced by the reducer 33, thereby driving the spiral auger 35 and the crushing blade 36 on the crushing shaft 34 to rotate. When the spiral auger 35 rotates, the pulp in the feed hopper 32 is squeezed and transported into the cylinder 2, and then the rotating crushing blade 36 shears and crushes the pulp entering the cylinder 2; wherein, the crushing blade 36 is obliquely arranged and installed on the outer ring of the crushing shaft 34, so that when the crushing blade 36 rotates, in addition to shearing and crushing the pulp, it can also push the crushed pulp to the right end of the cylinder 2, so that the pulp can also be transported to the right when crushed, thereby facilitating continuous feeding and crushing of the pulp.

[0048] See also Figures 1 - 3As shown, in one embodiment, the centrifugal mechanism 4 includes a sieve cylinder 41, a driving sprocket 42, and a transmission shaft 45. The sieve cylinder 41 is rotatably installed inside the cylinder body 2, and the sieve cylinder 41 is coaxially arranged with the crushing shaft 34.

[0049] The driving sprocket 42 is fixedly installed at one end of the crushing shaft 34. The transmission shaft 45 is rotatably installed at the top of the frame 1. Two ends of the transmission shaft 45 are respectively fixedly installed with a driven sprocket 44 and a gear 46. The driving sprocket 42 and the driven sprocket 44 are drivingly connected by a transmission chain 43. An outer ring at the end of the sieve cylinder 41 is fixedly installed with a gear ring 47 that is drivingly connected with the gear 46 in a meshing manner.

[0050] The liquid discharging assembly includes a liquid collecting tank 51. The liquid collecting tank 51 is arranged at the bottom of the end of the cylinder body 2. A liquid discharging conduit 52 is connected and installed at the bottom end of the liquid collecting tank 51.

[0051] When the crushing shaft 34 rotates for the transportation and feeding of the pulp as well as crushing, the pulp is conveyed into the inside of the sieve cylinder 41 through the spiral auger 35, and then the crushing blade 36 shears and crushes the pulp inside the sieve cylinder 41. At this time, the crushing shaft 34 drives the driving sprocket 42 to rotate synchronously, and the driving sprocket 42 drives the driven sprocket 44 to rotate through the transmission chain 43, thereby driving the transmission shaft 45 and the gear 46 to rotate. Then, the gear 46 meshes and drives the gear ring 47 to rotate in the reverse direction, so that the gear ring 47 drives the sieve cylinder 41 to rotate in the reverse direction relative to the crushing shaft 34. When the sieve cylinder 41 rotates in the reverse direction, it drives the crushed pulp inside it to perform a centrifugal motion, thereby centrifugally separating the juice in the crushed pulp. The centrifugally separated juice flows downward inside the cylinder body 2 and gathers in the liquid collecting tank 51, and finally is discharged through the liquid discharging conduit 52. The solid residue after centrifugal separation is gradually conveyed to the right end of the sieve cylinder 41 under the shearing and pushing of the crushing blade 36.

[0052] Please refer to Figures 1 - 7 As shown, in one embodiment, the pressure filtration assembly includes a material dropping port 53 and a pressure filtration box 59. The material dropping port 53 is opened on the cylinder wall at the end of the sieve cylinder 41. The pressure filtration box 59 is fixedly installed at the upper end inside the liquid collecting tank 51 and is located below the material dropping port 53. Filter holes are provided at the bottom end of the pressure filtration box 59.

[0053] A swing arm 56 is rotatably installed at the upper end inside the pressure filtration box 59. A lifting support rod 54 is rotatably installed at the top end of the swing arm 56. The bottom end of the swing arm 56 is drivingly connected with the discharging assembly. The bottom end of the lifting support rod 54 is fixedly installed with a lifting pressing plate 55.

[0054] The discharging assembly includes a discharging push plate 511 and a discharging motor 522. The discharging push plate 511 is slidably installed inside the filter press tank 59, and the discharging motor 522 is fixedly installed on the outer wall of the liquid collecting tank 51. A driving shaft 513 extending into the filter press tank 59 is drivingly installed at one end of the discharging motor 522. An eccentric wheel 512 is fixedly installed on the driving shaft 513. One end of the eccentric wheel 512 is rotatably installed with a connecting rod 514, and one end of the connecting rod 514 is rotatably connected to the discharging push plate 511;

[0055] The bottom end of the swing arm 56 is rotatably connected with a transmission rod 58, and one end of the transmission rod 58 is rotatably connected to the discharging push plate 511;

[0056] The blanking port 53 makes a circular motion along with the rotation of the sieve cylinder 41. When the blanking port 53 moves to the bottom end of the sieve cylinder 41, the solid residue in the sieve cylinder 41 falls into the right side end inside the filter press tank 59 through the blanking port 53. When it is necessary to carry out pressure filtration and discharging of the solid residue, first start the discharging motor 522, so that the discharging motor 522 drives the driving shaft 513 and the eccentric wheel 512 to continuously rotate. The eccentric wheel 512 can drive the discharging push plate 511 to reciprocate left and right inside the filter press tank 59 during rotation through the connecting rod 514. During the process of the discharging push plate 511 moving to the left, the bottom end of the swing arm 56 is pushed and rotated upward to the left through the transmission rod 58. At this time, the top end of the swing arm 56 rotates and moves downward to the right, thereby driving the lifting support rod 54 and the lifting pressing plate 55 to move downward to the right, so that the lifting pressing plate 55 squeezes the solid residue at the right side end inside the filter press tank 59 to further squeeze out the juice in the solid residue. The squeezed juice flows and is conveyed into the liquid collecting tank 51 through the filter holes at the bottom of the filter press tank 59. When the discharging push plate 511 moves, the bottom end of the swing arm 56 is pulled and reset downward to the right through the transmission rod 58. At this time, the top end of the swing arm 56 rotates and moves upward to the left to reset, and drives the lifting support rod 54 and the lifting pressing plate 55 to move upward to the left to reset, so that the lifting pressing plate 55 is staggered from the right-moving discharging push plate 511. Then the discharging push plate 511 continues to move to the right to push out the pressure-filtered solid residue from the filter press tank 59. Repeating this process, the pressure filtration and discharging process of the solid residue can be continuously carried out through the cooperation of the pressure filtration assembly and the discharging assembly;

[0057] Among them, the discharging push plate 511 can drive the lifting pressing plate 55 to lift through the combined transmission of the transmission rod 58 and the swing arm 56, making the driving of the lifting pressing plate 55 more convenient. At the same time, through the combined transmission of the transmission rod 58 and the swing arm 56, the discharging push plate 511 and the lifting pressing plate 55 can always be kept in a staggered state during the moving process, so that no collision interference will occur between the discharging push plate 511 and the lifting pressing plate 55, ensuring the normal progress of the pressure filtration and discharging process;

[0058] Further, a limiting rod 57 is rotatably installed inside the pressure filter box 59. The limiting rod 57 is arranged in parallel with the upper end of the swing arm 56, and one end of the limiting rod 57 is rotatably connected to the top end of the lifting support rod 54. The limiting rod 57 can cooperate with the swing arm 56 to limit the lifting support rod 54, so that the lifting support rod 54 always maintains a vertical state during the lifting movement, so that the lifting support rod 54 can vertically press down the lifting pressure plate 55 to improve the pressure filtration effect of the lifting pressure plate 55.

[0059] Please refer to Figures 3 - 6 As shown in the figure, in one embodiment, a top plate is provided on the top surface of the discharge push plate 511, a baffle plate 523 that is fixedly installed inside the pressure filter box 59 and slidably abuts against the top surface of the top plate, and a material guiding slope is provided on the top surface of the lifting pressure plate 55.

[0060] By providing a top plate on the top surface of the discharge push plate 511, when the discharge push plate 511 moves to below the discharge port 53 during the discharge pushing process, the solid residues falling from the discharge port 53 can fall onto the top surface of the top plate. Then, when the discharge push plate 511 moves leftward to reset, the baffle plate 523 can push the solid residues on the top surface of the top plate to fall to the right end of the discharge push plate 511, thereby preventing the solid residues from falling to the left end of the discharge push plate 511 and then being pushed back into the liquid collecting tank 51 by the discharge push plate 511 in the reverse direction, ensuring the normal progress of the pressure filtration and discharge processes. And by providing a material guiding slope on the top surface of the lifting pressure plate 55, when the solid residues fall onto the top surface of the lifting pressure plate 55, they can continue to slide downward along the material guiding slope and be conveyed to the top surface of the top plate or into the pressure filter box 59, facilitating the subsequent pressure filtration and discharge of the solid residues.

[0061] Please refer to Figures 3 - 6 As shown in the figure, in one embodiment, a guide groove 517 is opened on the side wall of the pressure filter box 59, and a limiting guide rod 519 that is fixedly installed on the side wall of the discharge push plate 511 and slidably clamped in the guide groove 517.

[0062] A material guiding plate 510 is arranged in the discharge port of the pressure filter box 59, and the material guiding plate 510 is rotatably connected to the pressure filter box 59 through an elastic hinge shaft 516. A chute 518 is also opened on the side wall of the pressure filter box 59, and a slider 521 is slidably clamped through the chute 518. A clamping groove 520 corresponding to the limiting guide rod 519 is provided on one side of the slider 521, and a push-pull rod 515 is rotatably installed on the other side of the slider 521. One end of the push-pull rod 515 is rotatably connected to the end of the material guiding plate 510.

[0063] Among them, the guide groove 517 can cooperate with the limit guide rod 519 to guide and limit the discharge push plate 511 during the left and right movement of the discharge push plate 511, making the movement process of the discharge push plate 511 more stable; initially, the material guide plate 510 can be vertically arranged in the discharge port of the filter press tank 59 under the torsional elastic force of the elastic hinge shaft 516 to seal and limit the discharge port, preventing solid residues from splashing out of the discharge port during the filtering process and ensuring the normal progress of the filtering process; when the discharge push plate 511 moves to the right to push and discharge the solid residues after the filtering is completed, the discharge push plate 511 can drive the limit guide rod 519 to move to the right and be clamped in the clamping groove 520 at the left end of the slider 521. Then, as the discharge push plate 511 and the limit guide rod 519 continue to move to the right, the limit guide rod 519 will push the slider 521 to move to the right. At this time, the slider 521 drives the material guide plate 510 to rotate and move through the push-pull rod 515, so that the material guide plate 510 is inclined downward and arranged on one side of the discharge port, thereby guiding and conveying the solid residues during the discharge through the material guide plate 510 and preventing the solid residues from falling into the liquid collecting tank 51 during the discharge process.
