Description

Technical Field

[0001] This invention relates to the technical field of coconut meal protein extraction equipment, and in particular to a coconut meal protein extraction equipment. Background Technology

[0002] Coconut meal protein extraction refers to the process of extracting useful components from a substance through solvent treatment, distillation, dehydration, and exposure to pressure or centrifugal force, or through other chemical or mechanical processes. Specifically, in the process of extracting protein from coconut meal, the first step is to crush the coconut meal into powder.

[0003] In existing equipment for crushing coconut meal raw materials, a rotating mechanism is generally used to drive the crushing blades to rotate inside a horizontal cylinder to crush the coconut meal. Since coconut meal is a hard material, in the actual crushing and processing stage, the current equipment only achieves primary crushing and cannot screen the crushed material. This results in uneven particle size due to insufficient crushing force, which affects the subsequent precision of coconut meal protein extraction. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a coconut meal protein extraction device to solve the technical problem mentioned in the background art of insufficient crushing degree of current crushing devices for relatively hard coconut meal raw materials.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a coconut meal protein extraction device, comprising an outer shell disposed on a support assembly, a feed pipe disposed on one side of the outer shell, an inner shell cavity disposed within the inner cavity of the outer shell, and a crushing mechanism for crushing and grinding coconut meal disposed within the inner shell cavity;

[0006] The crushing mechanism includes a main grinding roller and an auxiliary grinding roller disposed within the inner shell cavity. A first driving gear and a gear assembly are respectively disposed on both sides of the main grinding roller. A first driven gear is disposed on the first driving gear, and the central shaft end of the first driven gear is fixed to the auxiliary grinding roller. A second driven gear is disposed on the auxiliary grinding roller. A tubular ring for screening coconut meal particles is disposed on a section of the main grinding roller. A conveying auger is disposed inside the main grinding roller. A vacuum conveying assembly is disposed on the rod of the conveying auger. An end cap is also disposed on the main grinding roller.

[0007] Preferably, the gear assembly includes a second drive gear disposed on the main grinding roller, a fixing ring disposed on the second drive gear and on the outer wall of the end cover, a screw disposed on the fixing ring and the screw being rotatably disposed with the second drive gear, and a plurality of guide sleeves disposed between the fixing ring and the second drive gear.

[0008] Preferably, the vacuum delivery assembly consists of a vacuum delivery pipe and an end connected to a vacuum pump.

[0009] Preferably, a concave conical block is provided on one side of the inner cavity wall near the tubular ring.

[0010] Preferably, the second driven gear and the second driving gear are meshed together, the outer ring of the second driven gear is provided with a toothed ring, and the toothed ring is disposed on the inner wall of the inner shell cavity.

[0011] Preferably, two relatively distributed limiting arc grooves are provided on one side of the inner shell cavity, and each of the two limiting arc grooves is provided with a slot at one end, and one side of the slot is open and penetrating.

[0012] Preferably, two insert blocks are provided on the outer shell near the end where the slot is opened on the inner shell cavity.

[0013] Preferably, the support assembly includes a support frame disposed at the lower part of the outer casing, a base plate disposed on one side of the support frame, and a placement rack disposed on the other side of the support frame.

[0014] Preferably, a notch is provided on the inner shell cavity corresponding to the position of the feed pipe.

[0015] Preferably, a drive motor adapted for use is provided on the outer side of the upper shaft end of the conveying auger, and a slot is provided on the base plate, and the slot is configured to match the drive motor connected to the conveying auger.

[0016] By employing the above technical solution, the present invention provides a coconut meal protein extraction device, which has at least the following beneficial effects:

[0017] 1. Due to the design of the crushing mechanism, the power generated by starting the drive motor outside the conveying auger shaft drives the first driving gear fixed on it to rotate. This causes the first driven gears on both sides of the first driving gear to rotate, which in turn causes the corresponding auxiliary grinding roller fixed on the center of the end face of the first driven gear to rotate. At this time, the second driven gear fixed on the other end of the auxiliary grinding roller will drive the gear assembly meshed with its inner side to rotate under the action of rotational force. Subsequently, under the action of rotational force, the gear ring meshed with the outer side of the second driven gear and the inner shell cavity fixed on the outer periphery of the gear ring rotate in the inner cavity of the outer shell. This realizes the synchronous rotation of the main grinding roller and the two auxiliary grinding rollers horizontally distributed in the inner cavity of the inner shell cavity. The grinding teeth on the surface are used to grind and crush the coconut meal raw material entering through the feed pipe, which solves the problem of insufficient crushing degree of the current crushing device for the harder coconut meal raw material.

[0018] 2. This invention uses a base plate connected by a hinge on one side of the support frame to rotate the support frame 90 degrees to the upper surface of the base plate, so that the overall structure of the outer shell and inner shell cavity is placed vertically. Then, the second driving gear and the two driven gears on both sides that mesh with it are separated. Subsequently, under the combined action of the vacuum pump and the drive motor outside the conveying auger shaft, the coconut meal raw material particles sucked into the cavity of the main grinding roller under negative pressure are output towards the end cap by the spiral rotation force generated by the drive motor outside the conveying auger shaft, which plays a screening role, ensuring the uniformity of the output, and allowing for secondary grinding and crushing within the horizontally placed outer shell, resulting in good performance.

[0019] 3. Due to the setting of limiting arc grooves, slots and inserts, the inner shell cavity can be rotated at one end of the outer shell, so that the two inserts at one end of the outer shell can be rotated out from the two limiting arc grooves provided on one side of the inner shell cavity and pulled out from the slots to separate, realizing quick disassembly and assembly of the outer shell cavity and the inner shell cavity. The operation is simple and facilitates the subsequent cleaning of the relevant structures inside the inner shell cavity. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Regarding the technical problem of insufficient crushing degree of the current crushing device for relatively hard coconut meal raw materials, as mentioned above, please refer to... Figures 1-8 An embodiment of the present invention: a coconut meal protein extraction device includes an outer shell 2 mounted on a support assembly 1. The support assembly 1 includes a support frame 101 installed at the lower part of the outer shell 2. The support frame 101 is assembled at the lower part of the outer shell 2 by a snap fastener. A base plate 102 is hinged to one side of the support frame 101, and a placement rack 103 is welded to the other side of the support frame 101. The placement rack 103 can hold maintenance tools or end caps 4010. The base plate 102 has a groove 1. 1. The slot 11 is connected to the drive motor connected to the conveying auger 408. The feed pipe 10 is welded to the surface of the outer shell 2 through a slot on one side. Coconut meal raw material is added to the inside of the outer shell 2 through the feed pipe 10. The inner wall of the outer shell 2 is provided with an annular guide rail that contacts the outer surface of the inner shell cavity 3. The annular guide groove provided on the outer surface of the inner shell cavity 3 and the annular guide rail provided on the inner wall of the outer shell 2 realize the rotational connection of the inner shell cavity 3 and related structures on the inner shell cavity 3 in the inner shell 2.

[0033] To address the issue of insufficient crushing of harder coconut meal raw materials by current crushing devices, this technical solution includes a crushing mechanism 4 installed within the inner shell cavity 3 for crushing and grinding the coconut meal raw material. Specifically, this mechanism comprises a main grinding roller 401 and two auxiliary grinding rollers 402 housed within the inner shell cavity 3. Two auxiliary grinding rollers 402 are arranged on the same horizontal plane, opposite each other on either side of the main grinding roller 401. The grinding teeth on the outer walls of the main grinding roller 401 and auxiliary grinding rollers 402 are staggered to achieve thorough crushing of the coconut meal raw material. The main grinding roller 401 has a cavity. A conveying auger 408 is horizontally arranged inside. The outer side of the shaft end of the conveying auger 408 is fixedly connected to the output shaft of a drive motor that is compatible with it through a coupling. The outer side of a section of the shaft end of the conveying auger 408 is sleeved and fixed to a first driving gear 403. The first driven gear 405 on both sides of the first driving gear 403 is horizontally meshed and fixed to the auxiliary grinding roller 402. One side of the tube wall of the main grinding roller 401 is sleeved and fixed to a gear assembly 404. The gear assembly 404 includes a second driving gear 4041 sleeved on the main grinding roller 401 and a second driven gear 406. The second driven gear 406 meshes with the second driving gear 4041, and the outer ring of the second driven gear 406 meshes with the gear ring 6, which is welded and fixed to the inner wall of the inner shell cavity 3. The second driven gear 406 is fixedly connected to the corresponding auxiliary grinding roller 402. By starting the drive motor outside the shaft end of the conveying auger 408, the generated power will drive the first driving gear 403 fixed on it to rotate, causing the first driven gears 405 distributed on both sides of the first driving gear 403 to rotate horizontally meshing with each other, thereby causing the fixed end face of the first driven gear 405 to rotate. As the auxiliary grinding roller 402 rotates, the second driven gear 406, which is fixed at the other end of the auxiliary grinding roller 402, will drive the gear assembly 404 meshing with it to rotate under the action of rotational force. Subsequently, under the action of rotational force, the gear ring 6 meshing with the outer side of the second driven gear 406 and the inner shell cavity 3 fixed on the outer periphery of the gear ring 6 rotate in the inner cavity of the outer shell 2, realizing the synchronous rotation of the main grinding roller 401 and the two auxiliary grinding rollers 402 horizontally distributed in the inner cavity 3, and using the grinding teeth on the surface to grind and crush the coconut meal raw material entering through the feed pipe 10.

[0034] In this technical solution, to screen the crushed coconut meal raw material particles, a tubular ring 407 for screening coconut meal particles is rotatably connected to the main grinding roller 401. The surface of the tubular ring 407 is provided with multiple evenly distributed sieve holes of a certain size. A vacuum conveying assembly 409 is installed at the shaft end of the conveying auger 408 and partially inside the main grinding roller 401. The vacuum conveying assembly 409 consists of a vacuum conveying pipe and an end connected to a vacuum pump. The main grinding roller 401 is also fixedly assembled with the end cover 4010 by a threaded rotation. A slidingly connected fixing ring 4042 is fitted on the outer wall of the end cover 4010. 42 and the second driving gear 4041 are designed to be distributed relative to each other. The screw 4043 is mounted on the fixed ring 4042 using a bearing, and the outer thread of the screw 4043 is rotated and connected to the internal thread groove starting from the end face of the second driving gear 4041. Three guide sleeves 4044 are installed between the fixed ring 4042 and the second driving gear 4041, which are symmetrically distributed along the center. The guide sleeves 4044 provide limiting guidance for the second driving gear 4041 on the outer wall of the main grinding roller 401. On one side of the inner cavity 3, near the tubular ring 407, an integrally formed concave conical block 5 is used for discharging the coconut meal raw material particles after grinding and crushing. First, it passes through one side of the support frame 101. The hinged base plate 102 rotates the support frame 101 90 degrees to the upper surface of the base plate 102, so that the overall structure of the outer shell 2 and the inner shell cavity 3 is placed vertically. Then, the screw 4043 is rotated, and the external thread on the outer wall of the screw 4043 and the internal thread groove through the end face of the second drive gear 4041 are used to drive the second drive gear 4041 to move linearly under the guidance and limitation of the guide sleeve 4044. This causes the second drive gear 4041 to move away from the two meshing second driven gears 406 on both sides. At this time, the end of the vacuum conveying assembly 409 is started simultaneously. The vacuum pump connected to the shaft end of the conveying auger 408 and the drive motor outside the shaft end generate negative pressure suction under the action of the vacuum pump connected to the end. This pressure pressurizes the coconut meal raw material particles gathered on the concave surface of the concave conical block 5 and enters the internal cavity of the main grinding roller 401 through the screen holes provided on the surface of the tubular ring 407. At this time, under the action of the drive motor outside the shaft end of the conveying auger 408, the spiral rotation force generated will output the coconut meal raw material particles towards the end cover 4010. Then, the discharge operation is completed through the discharge channel opened through the end cover 4010. The remaining coconut meal raw material particles that have not passed through the screen holes can be subjected to secondary grinding and crushing in the subsequent horizontally placed outer shell 2.

[0035] In order to quickly separate the outer shell 2 and the inner shell cavity 3, the inner shell cavity 3 in this technical solution has two relatively distributed limiting arc grooves 7 on one side, and each of the two limiting arc grooves 7 has a slot 8 connected at one end. The slot 8 has an open through-hole design on one side. Two inserts 9 are welded to the end of the outer shell 2 near the slot 8 on the inner shell cavity 3, and the inserts 9 and the slot 8 are connected. By rotating the inner shell cavity 3 at one end of the outer shell 2, the two inserts 9 at one end of the outer shell 2 are rotated out from the two limiting arc grooves 7 on one side of the inner shell cavity 3 and pulled out from the slot 8. This realizes quick disassembly and assembly of the outer shell 2 and the inner shell cavity 3, which is simple to operate and facilitates the subsequent cleaning of the relevant structures inside the inner shell cavity 3.

[0036] In order to facilitate feeding, a notch is provided on the inner shell cavity 3 of this technical solution at the position corresponding to the feed pipe 10. The notch design will not affect the entry of coconut meal raw material through the feed pipe 10 when rotating.

The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
