Description

Technical Field

[0001] This invention relates to the field of material feeding technology, and in particular to an automatic feeding mechanism for a pulverizing and drying equipment for fresh materials into dry powder. Background Technology

[0002] With the high-quality development of modern pharmaceutical, food, and bioengineering industries, converting fresh materials into dry powder has become a core process in deep material processing. Dry powder products are widely used in traditional Chinese medicine granules, natural extracts, health foods, and food additives. In actual production, the characteristics of fresh materials to be processed vary significantly. Fruits and vegetables have a moisture content of 80%-95%, and the moisture is rich in water-soluble active ingredients. Therefore, both the solid and liquid components of fruits and vegetables need to be fed into the pulverizing and drying equipment together to retain the active ingredients. Animal organs have a moisture content of 70%-80%, but the free water is worthless. It is necessary to filter out the useless water and feed only the solid components into the pulverizing and drying equipment to reduce the energy consumption of the pulverizing and drying equipment. Root and rhizome medicinal materials have a moisture content of less than 30%, and no pretreatment is required. They can be directly pulverized and dried using loose soil pulverizing equipment. Therefore, different materials require different pretreatment methods. With the improvement of production automation, the ability to adapt feeding mechanisms to different pretreatment and feeding methods according to material characteristics has become an urgent need for industry development.

[0003] In the prior art, those skilled in the art have also provided technical solutions for automatic feeding of crushing and drying equipment. For example, Chinese Patent No. CN215234493U discloses an anti-clogging automatic feeding device for an integrated drying and grinding system. The anti-clogging automatic feeding device for an integrated drying and grinding system includes a base plate, a box is fixedly installed on the top of the base plate, and a feeding device and an anti-clogging device are provided on the base plate. During feeding, the feeding device can automatically feed the material and control the feeding speed of wheat to prevent the feeding port from being blocked.

[0004] However, the aforementioned existing technologies still have some shortcomings in the feeding process:

[0005] 1. The above-mentioned existing technology can only be adapted to the feeding of dry materials and cannot be adapted to the feeding of fresh materials. Furthermore, it cannot perform corresponding pretreatment based on the moisture content of the material and whether the liquid composition contains effective components. Therefore, the single feeding mode of dry materials cannot be adapted to materials with different moisture contents and liquid compositions, thus having limitations and being unable to adapt to the feeding of different materials.

[0006] 2. The existing technology described above cannot automatically and quickly switch the feeding mode according to the characteristics of different materials when feeding different materials. As a result, when changing the type of material during production, the machine needs to be stopped to adjust the feeding structure, resulting in low production efficiency and inability to meet the feeding needs of multiple materials.

[0007] Therefore, based on the above-mentioned viewpoints, there is still room for improvement in existing automated feeding methods. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides an automatic feeding mechanism for a pulverizing and drying device for fresh materials into dry powder. The mechanism includes a feeding cylinder installed at the feeding end of the device body for pulverizing and drying the material, used to convey the material into the device body for pulverizing and drying; a stabilizing frame mounted on the outer wall of the device body and supported at the bottom of the feeding cylinder for support and fixation; and a displacement plate with a horizontal perforation in the feeding cylinder, the width of which is greater than the inner diameter of the feeding cylinder, and the displacement plate slidingly passing through the perforation.

The equipment is equipped with a homogenization unit and a filtration unit. The feeding hole is used to directly convey low-moisture-content materials into the equipment body. The homogenization unit is used to mix high-moisture-content liquid materials containing effective components and then convey them into the equipment body.

The drive unit is located between the stabilizing frame and the displacement plate. It is used to drive the displacement plate to move back and forth, so that the displacement plate drives the feeding hole, homogenization unit or filtration unit to move into the feed cylinder and then convey the pre-treated materials with different moisture contents into the equipment body.

The diameter of the guide cylinder gradually decreases from top to bottom, and the inner wall of the guide cylinder gradually slopes downward from top to bottom. There is an annular gap between the inner wall of the guide cylinder and the conical barrel to allow the material to flow downward.

[0016] Preferably, the bottom of the guide cylinder is provided with a conical cover, which covers the outside of the conical barrel. The inner wall of the conical cover is provided with annular strips, and the outer wall of the conical barrel is provided with multiple sets of protrusions that are staggered with the annular strips. Each set of protrusions is evenly distributed along the circumference of the conical barrel. The adjacent annular strips and protrusions form a mixing channel for squeezing and mixing materials with high water content and effective components in the liquid.

[0022] The discharge hole has a drain hole that is connected to one end of the water receiving cylinder. The drain hole is connected to the outside by gradually tilting downwards. The bottom of the water receiving cylinder is tilted downwards on the side near the drain hole.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] I. This invention integrates feeding modes for direct conveying of low-moisture-content materials, homogenization of high-moisture-content materials containing effective components, and solid-liquid separation of high-moisture-content materials without effective components. These multiple feeding modes constitute differentiated treatment for different materials, allowing the feeding mode to be adjusted according to different types of materials. This enables the invention to adapt to fresh materials with various moisture contents, achieving multi-purpose functionality and improving its applicability. Furthermore, it completely solves the problem of loss of effective components or energy waste caused by using the same pretreatment for multiple types of materials.

[0025] II. This invention uses a conical barrel to drive multiple arc-shaped levers to move circumferentially, scraping off the material accumulated at the top of the guide cylinder and dropping it between the conical barrel and the guide cylinder. The annular bar slows down the speed of the material flowing down the conical barrel, and the fixed annular bar, in conjunction with the circumferentially moving protrusions, squeezes, crushes, grinds, and reassembles the material, so that the solid material and liquid effective components are mixed evenly to form a slurry containing small lumps, thereby retaining water-soluble effective components, effectively reducing the loss of effective components in the material, and improving the utilization rate of the material.

[0026] Third, this invention can remove moisture from materials with high water content and no effective components by squeezing and conveying them, thereby separating solid materials from liquids without effective components. Only solid materials are conveyed to the equipment body for crushing and drying, avoiding the entry of liquids without effective components into the equipment body and increasing energy consumption.

[0043] The following is in conjunction with the appendixFigures 1-9 The embodiments of the present invention will be described in detail below.

[0044] This application discloses an automatic feeding mechanism for a pulverizing and drying equipment for fresh materials into dry powder. It should be noted that the automatic feeding mechanism of this application is mainly used to transport different types of fresh materials into the pulverizing and drying equipment in different feeding modes. In terms of technical effect, it can adjust different feeding modes according to the moisture content of the fresh materials and whether they contain liquid effective components. Multiple feeding modes constitute differentiated treatment for different materials, which can realize multi-purpose use and solve the problem of loss of effective components or energy waste caused by using the same pretreatment for multiple types of materials.

[0045] Reference Figure 1 As shown, an automatic feeding mechanism for a pulverizing and drying device for fresh materials into dry powder includes a feeding cylinder 2, installed at the feeding end of the device body 1 for pulverizing and drying materials, used to transport materials into the device body 1 for pulverizing and drying; a stabilizing frame 3, set on the outer wall of the device body 1 and supported at the bottom of the feeding cylinder 2, used to support and fix the feeding cylinder 2; and a displacement plate 4, on which a horizontal perforation is opened, the width of which is greater than the inner diameter of the feeding cylinder 2, and the displacement plate 4 slides through the horizontal perforation. A sealing gasket is provided between the inner wall of the horizontal perforation and the displacement plate 4, and the sealing gasket only has a sealing function and does not interfere with or obstruct the movement of the displacement plate 4. The sealing gasket can prevent materials in the feeding cylinder 2 from flowing out through the gap between the displacement plate 4 and the horizontal perforation. The material seeps out through the gaps between the feed cylinders. The displacement plate 4 has multiple discharge holes 41 with a diameter larger than the inner diameter of the feed cylinder 2. Two of the discharge holes 41 are respectively equipped with a homogenization unit 6 and a water filtration unit 7. The drive unit 5 is located between the stabilizing frame 3 and the displacement plate 4. It is used to drive the displacement plate 4 to move back and forth, so that the displacement plate 4 can move the discharge holes 41, the homogenization unit 6 or the water filtration unit 7 into the feed cylinder 2 and then transport the pre-treated materials with different moisture contents to the equipment body 1. The discharge holes 41 without the homogenization unit 6 and the water filtration unit 7 are used to transport materials. Furthermore, the stabilizing frame 3 can optionally be equipped with a horizontal baffle (not shown in the figure) on the side near the homogenization unit 6 in a detachable manner to receive the material dripping down from the homogenization unit 6.

[0046] In the specific implementation process, firstly, the displacement plate 4 is moved by the drive unit 5, causing the displacement plate 4 to move the feeding hole 41, homogenization unit 6, or filtration unit 7 into the feeding cylinder 2 and connect with it, so as to determine the feeding mode according to the type of material to be processed. Secondly, the material to be crushed and dried is poured into the feeding cylinder 2. After passing through the feeding hole 41, homogenization unit 6, or filtration unit 7, the material is conveyed into the equipment body 1 for crushing and drying. Among them, the feeding hole 41 without the homogenization unit 6 and filtration unit 7 is used to directly convey low moisture content materials into the equipment body 1, and the homogenization unit 6 is used to... Materials with high moisture content and containing effective components in the liquid are stirred and mixed before being conveyed into the equipment body 1 to prevent the loss of effective components. The water filtration unit 7 is used to drain the water from the materials with high moisture content and no effective components in the liquid, reducing the energy waste generated when the equipment body 1 dries excess water. After solid-liquid separation, only the solid material is conveyed into the equipment body 1. In this way, the feeding mode can be adjusted according to the moisture content of the material and whether the liquid contains effective components, so as to realize multiple uses of one machine, improve the applicability of the invention, and completely solve the problem of loss of effective components or energy waste caused by using the same pretreatment for multiple types of materials.

[0047] It should be noted that since the diameter of the discharge hole 41 is larger than the inner diameter of the feed cylinder 2, and an annular guide cylinder 21 is also installed on the inner wall of the feed cylinder 2, the diameter of the annular guide cylinder 21 gradually decreases from top to bottom, further reducing the dispersion range of the material when it flows downward, so that the material can completely pass through the discharge hole 41. In addition, there is a gap between the lower end of the annular guide cylinder 21 and the upper end of the displacement plate 4 to avoid the displacement plate 4 from contacting the annular guide cylinder 21 and interfering when it moves. Therefore, when the material flows downward through the feed cylinder 2, the discharge hole 41 can completely receive the material, preventing the material from falling onto the displacement plate 4 and causing the seal between it and the horizontal perforation to fail.

[0048] Reference Figure 1 As shown, in order to facilitate the movement of the displacement plate 4 to drive the feeding hole 41, the homogenization unit 6 or the water filtration unit 7 to move into the feeding cylinder 2, a corresponding drive unit 5 is provided in this embodiment. Specifically, the drive unit 5 includes force plates 51 installed at both ends of the displacement plate 4 along its length. Two lead screws 52 are symmetrically mounted between the two force plates 51 along the width direction of the displacement plate 4. The two lead screws 52 are connected by belt drive. Two positioning frames 53 are symmetrically arranged at the upper end of the stabilizing frame 3 along the width direction of the displacement plate 4. The lead screws 52 pass through the positioning frames 53 by threaded connection. A pulley 54 is sleeved on the outer wall of one of the lead screws 52. A reciprocating motor 55 is mounted on the upper end of the positioning frame 53 through a motor frame. A transmission belt 56 is sleeved between the output shaft of the reciprocating motor 55 and the pulley 54. The reciprocating motor 55 is electrically connected to the controller inside the equipment body 1.

[0049] Furthermore, in this embodiment, two keyways 57 parallel to their axis are symmetrically formed on the lead screw 52, ​​and two key teeth 58 are provided on the inner wall of the pulley 54 that slide and engage in the keyways 57. The engagement of the key teeth 58 and the keyways 57 enables the pulley 54 to drive the lead screw 52 to rotate without interfering with the movement of the lead screw 52. Thus, when the pulley 54 drives the lead screw 52 to rotate, the lead screw 52 can reciprocate in conjunction with the positioning frame 53.

[0050] In the specific implementation process, when it is necessary to adjust the feeding mode according to the material with different moisture content and effective components, the controller in the main body 1 transmits a command to the reciprocating motor 55, so that the reciprocating motor 55 is powered on and started. The reciprocating motor 55 drives the lead screw 52 to rotate forward or backward through the transmission belt 56 and pulley 54. The pulley 54 drives the lead screw 52 to rotate. At the same time, the lead screw 52 rotates and drives the force plate 51, displacement plate 4, homogenization unit 6 and water filtration unit 7 to move as a whole under the action of the positioning frame 53. This causes the displacement plate 4 to drive the discharge hole 41, homogenization unit 6 or water filtration unit 7 to move into the feed cylinder 2. In this way, the feeding mode can be automatically adjusted according to the material with different moisture content and effective components, improving convenience.

[0051] Furthermore, in this embodiment, two support brackets 511 are symmetrically installed between the two force-bearing plates 51 along the width direction of the displacement plate 4. The support brackets 511 have strip grooves 512 parallel to the moving direction of the displacement plate 4 on the side away from the displacement plate 4. The upper end of the stabilizing frame 3 is also provided with two fixing plates 513 corresponding to the positions of the support brackets 511. The fixing plates 513 are provided with support blocks 514 that slide and engage in the strip grooves 512. Through the cooperation of the support blocks 514 and the strip grooves 512, the displacement plate 4 can be effectively supported, ensuring that the displacement plate 4 can bear the weight of the homogenization unit 6 and the water filtration unit 7, and ensuring its stability in reciprocating movement and static state.

[0052] Reference Figure 1As shown, since the liquid component of materials with high water content and containing effective components is rich in water-soluble effective components (such as fruits and vegetables), it can be dried and pulverized together with the solid material, which is beneficial to improving the utilization rate of the material. Therefore, in this embodiment, such materials can be homogenized. Specifically, the homogenization unit 6 includes a conical barrel 61 rotatably mounted on the inner wall of any one of the feeding holes 41 on the displacement plate 4. The opening of the conical barrel 61 is arranged downward. An annular groove is opened on the inner wall of the feeding hole 41. A rotating ring 62 is rotatably arranged in the annular groove. A sealing wear-resistant ring is provided to compensate for the gap between the annular groove and the rotating ring 62, preventing material from entering the annular groove and causing adverse effects. The rotating ring 62 is fixedly installed at the lower end of the conical barrel 61. Multiple annularly distributed material discharge holes 63 are evenly opened on the side of the conical barrel 61 near the rotating ring 62. A guide cylinder 64 is fixedly installed on the inner wall of the material discharge hole 41. The diameter of the guide cylinder 64 gradually decreases from top to bottom, and the inner wall of the guide cylinder 64 gradually slopes downward from top to bottom. There is an annular gap between the inner wall of the guide cylinder 64 and the conical barrel 61 to allow the material to flow downward.

[0053] Furthermore, in this embodiment, a conical cover 65 is provided at the bottom of the guide cylinder 64. The conical cover 65 covers the outside of the conical barrel 61, and an annular strip 66 is provided on the inner wall of the conical cover 65. Multiple sets of protrusions 67 are provided on the outer wall of the conical barrel 61, which are distributed alternately with the annular strip 66. Each set of protrusions 67 is evenly distributed around the circumference of the conical barrel 61. The adjacent annular strips 66 and protrusions 67 form a mixing channel for extruding and mixing materials with high water content and effective components in the liquid.

[0054] A gear ring 68 is fitted on the outer wall of the rotating ring 62. A control motor 69 is installed inside the displacement plate 4. A blind hole for installing the control motor 69 is opened at the upper end of the displacement plate 4. This not only allows the control motor 69 to dissipate heat when it is running, but also facilitates the installation of the control motor 69. The control motor 69 is electrically connected to the controller inside the equipment body 1. The output shaft of the control motor 69 is fixedly fitted with a transmission gear 60 that meshes with the gear ring 68.

[0055] It should be further explained that, in this embodiment, a support ring 611 is fixedly sleeved on the upper outer wall of the conical barrel 61, and a plurality of annularly distributed arc-shaped levers 612 are evenly arranged on the outer wall of the support ring 611. The arc-shaped concave surface of the arc-shaped lever 612 faces the rotation direction of the conical barrel 61, and there is a gap between the lower end of the arc-shaped lever 612 and the guide cylinder 64. This gap is smaller than the diameter of the solid material, which avoids friction and can move the material at the upper end of the guide cylinder 64.

[0056] In the specific implementation process, when feeding materials with high water content and containing effective components in the liquid, the controller in the main body 1 controls the displacement plate 4 to move the homogenization unit 6 into the feeding cylinder 2. The controller transmits a command to the control motor 69, which is then energized and started. The control motor 69 drives the transmission gear 60 to rotate. The transmission gear 60, in conjunction with the gear ring 68, drives the rotating ring 62 and the conical barrel 61 to rotate synchronously. During this period, the conical barrel 61 drives the protrusion 67 to move circumferentially. When the material flows downward from the feeding cylinder 2, it flows into the mixing channel through the annular gap between the conical barrel 61 and the guide cylinder 64. The annular bar 66 can block the material and slow down the speed of the material flowing downward along the conical barrel 61. The fixed annular bar 66 and the circumferentially moving protrusion 67 work together to squeeze, crush, and circumferentially grind and reassemble the material, so that the solid material and the liquid effective components are mixed evenly to form a slurry containing small lumps, thereby retaining the water-soluble effective components and effectively reducing the loss of the effective components of the material.

[0057] As the conical barrel 61 rotates, it drives multiple arc-shaped levers 612 to move circumferentially through the support ring 611. This causes the arc-shaped levers 612 to scrape off the material accumulated on the upper end of the guide cylinder 64 and drop it onto the conical barrel 61, thereby avoiding the blockage caused by the material accumulating on the upper end of the guide cylinder 64 and not being able to fall completely, thus improving the feeding efficiency.

[0058] Reference Figure 1 As shown, materials with high water content and no effective components in the liquid (such as animal organs) need to be dried by the equipment body 1 after being transported to the equipment body 1, resulting in unnecessary energy waste. Therefore, in this embodiment, the liquid components in such materials can be filtered out. Specifically, the water filtration unit 7 is set in the discharge hole 41 on the side away from the homogenization unit 6. The water filtration unit 7 includes two symmetrically opened connecting grooves on the side wall of the discharge hole 41. The connecting grooves are connected to the discharge hole 41, and a conveyor belt 71 is rotatably installed between the two connecting grooves and the discharge hole 41. Multiple rotating shafts 72 for supporting the two conveyor belts 71 are rotatably arranged on the inner wall of the connecting grooves and the discharge hole 41. The upper ends of the conveyor belts 71 gradually slope downwards on the side that is close to each other, which facilitates the conveying of materials between the two conveyor belts 71. The two conveyor belts 71 squeeze and drain the materials. Multiple anti-slip strips are evenly spaced on the outer wall of the conveyor belts 71 to increase friction when conveying materials. The outer walls of the two shafts 72 at two corresponding positions on the side that is close to each other of the two conveyor belts 71 are fitted with intermeshing linkage gears 73. The displacement plate 4 has a mounting groove 74. A positioning motor 75 connected to any one of the shafts 72 is installed in the mounting groove 74. The control motor 69 is electrically connected to the controller inside the equipment body 1. The mounting groove 74 facilitates the installation and heat dissipation of the positioning motor 75.

[0059] Furthermore, in this embodiment, the water filtration unit 7 also includes a water receiving cylinder 76 disposed on the inner wall of the discharge hole 41 of the conveyor belt 71. The water receiving cylinder 76 is located below the conveyor belt 71, and a guide plate 77 is disposed on the upper end of the water receiving cylinder 76. The middle part of the guide plate 77 gradually slopes upward, and there is space between the two sides of the guide plate 77 along its length direction and the inner wall of the discharge hole 41 for the material to fall downward, so that after the conveyor belt 71 conveys the material downward to the upper end of the guide plate 77, the material falls downward along the inclined direction of the guide plate 77. Multiple filter groups are evenly spaced on the guide plate 77, and each filter group includes multiple evenly spaced filter groups. The drain hole 78 has a common water-slowing groove 79 at its upper end. The water-slowing groove 79 has a downward-concave arc-shaped concave surface on the side away from the middle of the guide plate 77. The multiple water-slowing grooves 79 are used to slow down the flow rate of the liquid, so that the liquid is discharged downward through the drain hole 78 when it passes through the water-slowing groove 79, thereby achieving effective separation of solid materials and liquids. The discharge hole 41 has a drain hole 70 inside that is connected to one end of the water receiving cylinder 76. The drain hole 70 is connected to the outside by gradually tilting downward. The bottom of the water receiving cylinder 76 is gradually tilted downward on the side near the drain hole 70, which facilitates the discharge of liquid in the water receiving cylinder 76.

[0060] In the specific implementation process, when it is necessary to feed materials with high water content and no effective components in the liquid, the controller in the main body 1 controls the displacement plate 4 to move the water filtration unit 7 into the feed cylinder 2. Then, the controller transmits a command to the positioning motor 75 to start the positioning motor 75. The positioning motor 75 drives the rotating shaft 72 connected to it to rotate. Through the linkage gear 73, the rotating shafts 72 on both sides of the discharge hole 41 can rotate in opposite directions. The rotating shafts 72 drive the conveyor belts 71 to rotate synchronously, and the conveyor belts 71 on both sides of the discharge hole 41 rotate in opposite directions. When the material falls between the two conveyor belts 71 after passing through the feed cylinder 2, the material mixed in with the material is removed. The liquid flows downward along the conveyor belt 71, and flows into the water receiving cylinder 76 through the drain hole 78 and the slow water tank 79. The conveyor belt 71 can squeeze the material and push it downward to squeeze out excess water absorbed by the material. The squeezed water also flows into the water receiving cylinder 76 through the drain hole 78 and the slow water tank 79. The liquid in the water receiving cylinder 76 flows into the drain hole 70 and is discharged to the outside. This achieves the separation of solid material and liquid without effective components, so that the solid material falls into the equipment body 1 along the guide plate 77 for crushing and drying, thereby avoiding the liquid without effective components from entering the equipment body 1 and increasing energy consumption.

[0061] During operation: Step 1: When the feeding mode needs to be adjusted according to the different moisture content and effective components of the material, the controller in the main body 1 transmits a command to the reciprocating motor 55, so that the reciprocating motor 55 is powered on and started. The reciprocating motor 55 drives the lead screw 52 to rotate forward or backward through the transmission belt 56 and pulley 54. The pulley 54 drives the lead screw 52 to rotate. Under the action of the positioning frame 53, the lead screw 52 drives the displacement plate 4 to move, so that the displacement plate 4 drives the feeding hole 41, the homogenization unit 6 or the water filtration unit 7 to move into the feeding cylinder 2, thereby automatically adjusting the feeding mode according to the different moisture content and effective components of the material.

[0062] Step 2: When it is necessary to convey materials with low moisture content, the displacement plate 4 drives the discharge hole 41, which is not equipped with the homogenization unit 6 and the water filtration unit 7, to move into the feed cylinder 2, so that the discharge hole 41 is connected to the feed cylinder 2, and the material is directly conveyed into the equipment body 1 through the feed cylinder 2 and the discharge hole 41 for crushing and drying.

[0063] Step 3: When feeding materials with high moisture content and containing effective components into the liquid, the controller in the main body 1 controls the displacement plate 4 to move the homogenization unit 6 into the feeding cylinder 2. The controller transmits instructions to the control motor 69, causing the control motor 69 to drive the transmission gear 60 to rotate. The transmission gear 60, in conjunction with the gear ring 68, drives the rotating ring 62 and the conical barrel 61 to rotate synchronously. When the material flows downward from the feeding cylinder 2, the conical barrel 61 drives the arc-shaped lever 612 to scrape down the material accumulated at the top of the guide cylinder 64, allowing the material to enter between the conical barrel 61 and the guide cylinder 64. Through the fixed ring bar 66 and the circumferentially moving protrusion 67, the material can be squeezed, crushed, and circumferentially ground and reconstituted, so that the solid material and the liquid effective components are mixed evenly to form a slurry containing small lumps, thereby retaining the water-soluble effective components and effectively reducing the loss of the effective components of the material.

[0064] Step 4: When feeding materials with high moisture content and no effective components into the liquid, the controller in the main body 1 controls the displacement plate 4 to move the water filter unit 7 into the feeding cylinder 2. Then, the controller transmits a command to the positioning motor 75 to start the positioning motor 75. The positioning motor 75 drives the rotating shaft 72 connected to it to rotate. Through the rotating shaft 72 and the linkage gear 73, the conveyor belts 71 on both sides of the discharge hole 41 rotate in opposite directions. When the material falls between the two conveyor belts 71 after passing through the feeding cylinder 2, the liquid mixed in the material flows down the conveyor belt 71 into the water receiving cylinder 76. When the conveyor belt 71 conveys the material downward, it can squeeze out the excess water absorbed in the material. The squeezed water also flows into the water receiving cylinder 76. The liquid in the water receiving cylinder 76 flows into the drain hole 70 and is discharged to the outside. This achieves the separation of solid material and liquid without effective components, so that the solid material falls into the main body 1 along the guide plate 77 for crushing and drying, thereby avoiding the liquid without effective components from entering the main body 1 and increasing energy consumption.
