Description

Technical Field

[0001] The present invention relates to the technical field of conveying for industrial bio - enzyme production, and particularly to a conveying device with a cleaning function for industrial bio - enzyme production. Background Art

[0002] During the production process of industrial bio - enzymes, the transfer of raw materials is involved. In order to maintain the integrity of the raw materials during the transfer process, a screw conveyor is usually used to process the raw materials. The principle of the screw conveyor is to lift or advance the materials through the extrusion of the materials during the rotation of the auger. Among the raw materials used for the production of industrial bio - enzymes, there are many granular raw materials. To achieve the effect of saving the feeding time of the granular raw materials, the existing method of feeding the granular raw materials into the screw conveyor is to put a large amount of granular raw materials into the screw conveyor all at once. However, this method will increase the shear force between the granular raw materials in the screw conveyor, thus affecting the self - state of the granular raw materials. In the lightest case, cracks will appear in the granular raw materials, and in the worst case, the granular raw materials will break. After the granular raw materials break, powder will be generated, and this powder will enter the gap between the auger and the screw conveyor housing, thereby increasing the friction between the two, exacerbating the wear of the parts in the screw conveyor, and affecting the service life of the screw conveyor.

The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0029] To solve the problem that the existing way of feeding granular raw materials will increase the shear force of the spiral conveyor on the granular raw materials, resulting in the cracking of the granular raw materials, and increase the friction between the auger and the spiral conveyor housing, thus affecting the subsequent state of the granular raw materials.

[0030] The present invention controls the filling height of the granular raw materials in the spiral conveyor by controlling the feeding frequency of the granular raw materials in the feeding member 102, so as to avoid excessive filling of the granular raw materials in the spiral conveyor, causing cracks and fragmentation of the granular raw materials, and resulting in the powder in the fragmented granular raw materials entering the gap between the auger and the spiral conveyor, thereby exacerbating the wear of the parts in the spiral conveyor and extending the service life.

[0031] Embodiment 1: A conveying device with a cleaning function for industrial biocatalyst production, as Figures 1-7 shown, includes a feeding member 101. On the left side inside the feeding member 101, there is a feeding cavity 1011, and on the right side inside the feeding member 101, there is a first cavity 1012. The capacity of the feeding cavity 1011 is greater than that of the first cavity 1012. On the right part of the upper side of the feeding member 101, there is a feeding member 102 fixedly connected to the right side inside the feeding cavity 1011. The feeding member 101 is composed of a feeding shell and three inclined plates fixedly connected to each other. One of the inclined plates in the feeding member 101 is located below the feeding shell, and the remaining two inclined plates in the feeding member 101 are located in the lower middle part of the feeding shell and are symmetrically distributed front and back, shortening the single-drop distance of the granular raw materials, stabilizing the feeding state of the granular raw materials, and reducing the impact force received by the granules. On the front part of the left side of the feeding member 101, there is a discharge port 103 fixedly connected to the left side of the feeding cavity 1011. Inside the feeding member 101, there is a spiral conveying member 104 rotatably connected in a limited and sealed manner. The spiral conveying member 104 is located inside the feeding cavity 1011. On the right side of the feeding member 101, there is a first driving member 105. The first driving member 105 is a single-axis driving motor, and the output shaft of the first driving member 105 is fixedly connected to the spiral conveying member 104. In the middle of the feeding member 102, there is a feeding shell 106 fixedly connected. On the upper side of the feeding shell 106, there is an inclined surface for guiding the falling of the granular raw materials. Inside the feeding member 102, there is a U-shaped shell 107 fixedly connected below the feeding shell 106. Inside the U-shaped shell 107, there are two elastic air bags 108 fixedly connected symmetrically front and back. Figure 6The middle elastic airbag 108 is in an air intake and expansion state. There are two symmetrically arranged L-shaped plates 109 in a front-back symmetry that are in a limit-sealed sliding connection between the U-shaped shell 107 and the material guiding shell 106. The two symmetrically arranged L-shaped plates 109 in a front-back symmetry are in mutual contact. After the two symmetrically arranged L-shaped plates 109 in a front-back symmetry are in contact, there are gaps on both the front and back sides. These gaps are used to guide the falling of granular raw materials. The two symmetrically arranged L-shaped plates 109 in a front-back symmetry are both in a plugging fit with the feeding part 102. The two symmetrically arranged L-shaped plates 109 in a front-back symmetry are located between the symmetric elastic airbags 108. When the elastic airbags 108 exhaust and contract, the back sides of the two L-shaped plates 109 are respectively in contact with the front and back sides inside the feeding part 102, thereby realizing the plugging of the feeding part 102. An air intake component for controlling the symmetric elastic airbags 108 is arranged inside the material guiding part 101. A first cleaning component for cleaning the materials is arranged inside the material guiding part 101. An air extraction component for cleaning the powder inside it is arranged inside the material guiding part 101.

[0032] As Figure 2 , Figure 3 and Figures 5-7 shown, the air intake component includes a first air guiding shell 201. The first air guiding shell 201 is fixedly connected to the material guiding part 101 and is located on the right side inside the first cavity 1012. The first air guiding shell 201 is in a limit-sealed rotational fit with the spiral feeding part 104. A second cavity 1041 is arranged on one side of the spiral feeding part 104 located inside the first cavity 1012. On one side of the spiral feeding part 104 located inside the first cavity 1012, there are first air holes that are symmetrically arranged left and right and are in a circular array. The first air guiding shell 201 is communicated with the second cavity 1041 through the first air holes on the right side of the spiral feeding part 104 in a circular array. The first air guiding shell 201 is communicated with a communicating pipe that penetrates the material guiding part 101 and is communicated with both of the symmetric two elastic airbags 108 in a front-back symmetry, so as to enable the first air guiding shell 201 to convey gas into the symmetric two elastic airbags 108 in a front-back symmetry. A second air guiding shell 202 that is in a sealed rotational and sliding fit with the spiral feeding part 104 is in a limit-sliding connection on the left side of the first air guiding shell 201. A spring is arranged between the second air guiding shell 202 and the first air guiding shell 201. This spring is used to drive the second air guiding shell 202 to slide back to its original position. The second air guiding shell 202 is communicated with the second cavity 1041 through the first air holes on the left side of the spiral feeding part 104 in a circular array. A first air pipe 203 that penetrates the material guiding part 101 is fixedly connected and communicated to the rear side of the second air guiding shell 202. A control component is arranged inside the material guiding part 101. The control component is used to control the position of the second air guiding shell 202 on the spiral feeding part 104.

[0033] As Figure 6 and Figure 7As shown in the figure, a third cavity 1042 is provided on the left side inside the spiral feeding member 104. The capacity of the third cavity 1042 is larger than that of the second cavity 1041. A second air hole in an annular array is provided on the right side of the spiral feeding member 104. The second air holes on the right side of the spiral feeding member 104 are located on the left side of all the first air holes thereon. The second air guide shell 202 is communicated and cooperated with the third cavity 1042 through the second air holes in the annular array on the spiral feeding member 104. When gas enters the third cavity 1042, it cools the spiral feeding member 104 and extends the service life of the spiral feeding member 104. An exhaust port is provided on one side of the feeding member 101 close to the first cavity 1012. The first cavity 1012 is communicated with the outside through the exhaust port on the feeding member 101 to discharge the pressure in the first cavity 1012.

[0034] As Figures 5-7 shown in the figure, the control assembly includes a second driving member 301. The second driving member 301 is an electric push rod. The second driving member 301 is fixedly connected to the feeding member 101 and is located inside the first cavity 1012. A fixed ring 302 is fixedly connected to the telescopic end of the second driving member 301. An arc-shaped block 303 that is limited in rotation and slidably connected to the spiral feeding member 104 is connected to the fixed ring 302 in a limited manner. An inclined surface is provided on the left side of the second air guide shell 202. The inclined surface on the left side of the second air guide shell 202 is in extrusion cooperation with the arc-shaped block 303. The inner diameter of the fixed ring 302 is larger than the outer diameter of the second air guide shell 202.

[0035] As Figure 5 and Figure 6 shown in the figure, the first cleaning assembly includes a first air outlet shell 401. The first air outlet shell 401 is fixedly connected to the right side inside the feeding member 101. The first air outlet shell 401 is located below the feeding member 102. The first air outlet shell 401 is provided with an air outlet facing the feeding member 102. The feeding member 101 is fixedly connected with a second air guide pipe 402 that is fixedly connected and communicated with the first air outlet shell 401. The second air guide pipe 402 is used to convey gas to the first air outlet shell 401. A second air outlet shell 403 is fixedly connected inside the feeding member 102 and is located above the first air outlet shell 401. The second air outlet shell 403 is provided with two groups of air outlets that are symmetrically arranged front and back. The gas ejected from all the air outlets of the second air outlet shell 403 cleans and decelerates the granular raw materials passing through the feeding member 102. The second air outlet shell 403 is communicated with the first air outlet shell 401 through a connecting pipe 701. A breathable plate 404 is fixedly connected inside the feeding member 102 and is located between the second air outlet shell 403 and the first air outlet shell 401. The breathable plate 404 is located in the middle of the horizontal position of the feeding member 102. There are gaps for guiding the granular raw materials to fall between the front and back sides of the breathable plate 404 and the feeding member 102. The breathable plate 404 is located on the lower side inside the feeding member 102 and is inclined towards the lower left side.

[0036] As Figures 3-6 、 Figure 8 andFigure 10 As shown in the figure, the air extraction assembly includes an air extraction housing 501, which is fixedly connected to the left side of the feeding member 102. The feeding member 102 is located between the second air outlet housing 403 and the air permeable plate 404. The air extraction housing 501 is used to extract dust passing through the feeding member 102. The air extraction housing 501 is fixedly connected and communicated with an air extraction pipe 502. The guiding member 101 is provided with a sliding frame 503, and the sliding frame 503 is fixedly connected with an air extraction member 504 communicated with the guiding member 101. Filters are provided in both the air extraction housing 501 and the air extraction member 504, and the air extraction member 504 is communicated with the air extraction pipe 502.

[0037] When the existing screw conveyor transports granular raw materials, in addition to the factor that the granular raw materials are overfilled in the screw conveyor, resulting in the fragmentation of the granular raw materials and the generation of powder, the granular raw materials will also be fragmented and even generate powder during the transportation or other processes before being put into the screw conveyor. On the premise of controlling the feeding frequency of the granular raw materials, the present invention can also remove the powder inside the screw conveyor. The details are as follows:

[0038] Before transporting the granular raw materials, the staff first connect the feeding hopper to the upper side of the feeding member 102 (for example), and then connect the two air outlets of the external air supply device to the rear sides of the first air duct 203 and the second air duct 402 respectively. Subsequently, connect the front sides of the air extraction pipe 502 and the discharge port 103 to the air inlet of the external air extraction device and the feeding part of the position where the granular raw materials are required respectively, so as to complete the preparatory actions before transporting the granular raw materials.

[0039] After completing the preparatory actions before transporting the granular raw materials, the staff start the first driving member 105, so that the output shaft of the first driving member 105 drives the screw conveying member 104 to rotate in the guiding cavity 1011. During the rotation of the screw conveying member 104, the arc-shaped block 303 is driven to rotate along the fixed ring 302. Subsequently, the staff control the external air supply device to send gas into the first air duct 203 and the second air duct 402, and finally the staff control the external air extraction device to extract the gas in the air extraction pipe 502.

[0040] After the above operation process is completed, the gas in the second air duct 402 is transported to the first air outlet housing 401. Part of the gas in the first air outlet housing 401 is ejected from the air outlet on its left side to blow the granular raw materials, and clean the dust adhering to the granular raw materials (the granular raw materials will adhere to dust because of the problems before the granular raw materials are put into this device, which has been mentioned above). Another part of the gas in the first air outlet housing 401 enters the second air outlet housing 403 through the adjacent connecting pipe. The second air outlet housing 403 ejects the gas from all its air outlets, so that the gas contacts the granular raw materials and sorts the granular raw materials at the same time. The heavier granular raw materials fall onto the air-permeable plate 404. The gas ejected from the air outlet on the first air outlet housing 401 passes through the air-permeable plate 404 to blow the heavier particulate matters. The heavier granular raw materials finally fall into the material guiding cavity 1011, while the lighter granular raw materials directly fall into the material guiding cavity 1011 along the front and back sides inside the feeding part 102.

[0041] During the process that the granular raw materials pass through the feeding part 102, the external exhaust equipment extracts the gas and dust in the feeding part 102 and the material guiding cavity 1011 through the exhaust pipe 502, the exhaust housing 501 and the exhaust part 504, so as to realize the pretreatment of the particulate raw materials.

[0042] After the treated granular raw materials fall into the right side of the material guiding cavity 1011, under the continuous rotation of the spiral feeding part 104, the spiral feeding part 104 drives the granular raw materials to move leftward and be discharged from the discharge port 103, so as to realize the transportation of the granular raw materials.

[0043] When the spiral feeding part 104 rotates to Figure 5 the state shown in the figure, the springs adjacent to the second air guiding housing 202 are compressed. At this time, the gas is introduced into the second cavity 1041 through the first air duct 203, the second air guiding housing 202 and the first air holes located in the left annular array on the right part of the spiral feeding part 104, and flows into the first air guiding housing 201 through the first air holes in the right annular array of the second cavity 1041. The gas enters the two elastic air bags 108 through the first air guiding housing 201 and the adjacent connecting pipe, so that the elastic air bags 108 expand and drive the adjacent L-shaped plates 109 to move to the side away from the material guiding housing 106 until the back sides of the two L-shaped plates 109 are both attached to the inner side of the feeding part 102, thereby disconnecting the connection between the upper and lower sides in the feeding part 102 and realizing the effect of blocking the feeding part 102.

[0044] After the spiral feeding member 104 rotates to a position where the arc-shaped block 303 is not in contact with the second air guide housing 202, the second air guide housing 202 moves to the left under the action of the adjacent spring. After the second air guide housing 202 moves to the left, it communicates with the second air holes arranged in a circular array on the right side of the spiral feeding member 104, enabling the second air guide housing 202 to transport gas through the second air holes arranged in a circular array on the right side of the spiral feeding member 104 into the third cavity 1042, so as to cool down the spiral feeding member 104. After the gas no longer enters the two elastic air bags 108 through the first air guide housing 201 and the adjacent connecting pipes, under the action of the elasticity of the elastic air bags 108 themselves, the two L-shaped plates 109 move towards each other, thereby losing the blockage of the feeding member 102, so as to achieve the intermittent feeding of the feeding member 102 and maintain the amount of granular raw materials in the material guiding cavity 1011.

[0045] During the process of the elastic air bag 108 driving the adjacent L-shaped plate 109 to reset, the gas inside it enters the second cavity 1041 through the adjacent connecting pipe, the first air guide housing 201, and the first air holes arranged in a circular array on the right side of the spiral feeding member 104, and is discharged through the first air holes arranged in a circular array on the left side of the spiral feeding member 104, so as to enter the first cavity 1012 and be discharged from the exhaust port on the right side of the material guiding member 101.

[0046] When the spiral feeding member 104 rotates to contact the arc-shaped block 303, it contacts the arc-shaped block 303 under the action of the inclined surface on the left side of the second air guide housing 202, enabling the arc-shaped block 303 to squeeze the second air guide housing 202 to the right. During the process of the second air guide housing 202 moving to the right, it squeezes the adjacent spring and makes the second air guide housing 202 communicate with the first air holes arranged in a circular array on the left side of the spiral feeding member 104. The subsequent process can be repeated as above.

[0047] When the transportation of the granular raw materials is completed, the staff can turn off all the above-mentioned electric driving members.

[0048] In Embodiment 1, the sliding frame 503 is fixedly connected to the material guiding member 101, while in Embodiment 2, the sliding frame 503 is in a limit-sealed sliding connection with the material guiding member 101.

[0049] Before the granular raw materials are put into the spiral conveyor, due to external environmental reasons (such as the granular raw materials being placed in a humid area), the granular raw materials will contain moisture and thus agglomerate. After the agglomerated granular raw materials are separated, the moisture in the agglomerated granular raw materials will affect the environment inside the spiral conveyor, resulting in the granular raw materials sticking to the spiral feeding member inside the spiral conveyor, so that the shear force inside the spiral conveyor becomes larger, thereby affecting the subsequent transportation of the granular raw materials.

[0050] The present invention adopts a method of pre-treating granular raw materials, so that the granular raw materials can be processed into small particles before entering the spiral feeder, preventing the agglomerated granular raw materials from blocking the feeding port of the spiral feeder, resulting in a low conveying efficiency of the spiral feeder, and adopts an intermittent scraping method for the spiral conveying member to clean the outside of the spiral conveying member.

[0051] Embodiment 2: On the basis of Embodiment 1, as Figure 3 , Figure 8 and Figure 10 shown, it further includes a second cleaning component arranged on the guiding member 101. The second cleaning component is used to clean the powder in the guiding member 101. The second cleaning component includes an L-shaped fixing member 601 fixedly connected to the front side of the guiding member 101. A sliding rod 602 is connected to the left side of the L-shaped fixing member 601 in a limited sliding manner. A tension spring fixedly connected to the sliding rod 602 is fixedly connected inside the L-shaped fixing member 601. This tension spring is used to drive the sliding rod 602 to move in a reset manner. The sliding rod 602 is fixedly connected with a third driving member 603 in a horizontal linear array. The third driving member 603 is an electric push rod. The third driving members 603 in the horizontal linear array all penetrate through the sliding frame 503 and are in sliding cooperation with it. The telescopic parts of the third driving members 603 in the horizontal linear array are all in contact and cooperation with the spiral conveying member 104. The sliding frame 503 is in a limited sealing sliding cooperation with the guiding member 101. By the telescopic part of the third driving member 603 protruding and contacting the spiral conveying member 104, the adhesives on the outside of the spiral conveying member 104 are cleaned.

[0052] As Figure 6 shown, two fixing plates 1091 are fixedly connected to the facing sides of two L-shaped plates 109 that are symmetrical front and back. The fixing plates 1091 are connected to a rotating rod 1092 that rotates and slides with the guiding shell 106 in a limited rotation manner. The rotating rod 1092 is fixedly connected with an inclined rod that rotates and slides with the guiding shell 106. During the process of the rotating rod 1092 moving along the guiding shell 106, under the action of the inclined rod on the outside of the rotating rod 1092, the rotating rod 1092 rotates during the moving process, so as to stir the surrounding granular raw materials. A lifting component for changing the material state in the guiding member 101 and the guiding cavity 1011 is arranged in the spiral conveying member 104.

[0053] As Figures 9-11As shown in the figure, the lifting component includes a connecting pipe 701 fixedly connected inside the spiral feeding part 104. The left side of the connecting pipe 701 is a flexible pipe, and the flexible pipe on the left side of the connecting pipe 701 is fixedly connected to the left side of the spiral feeding part 104. A dust detection module and a counter (both are not marked in the figure) are arranged on the part of the material guiding part 101 located in the material guiding cavity 1011. The dust detection module is used to monitor the amount of dust in the material guiding cavity 1011, and the counter is used to monitor the number of turns of the spiral feeding part 104. The spiral feeding part 104 is limited and sealed and slidably connected with a transverse linear array of sliding plates 702, and the transverse linear array of sliding plates 702 are all fixedly connected to the connecting pipe 701. An air guiding cavity 802 is arranged on the left side inside the material guiding part 101. The air guiding cavity 802 is composed of a rectangular cavity and a cylindrical cavity that communicate with each other. A sealing part 703 located inside the air guiding cavity 802 is fixedly connected to the left side of the material guiding part 101. The sealing part 703 is composed of a circular ring and a cylindrical shell that are fixedly connected to each other. A liquid guiding part 704 fixedly connected to the spiral feeding part 104 is limited and sealed and rotatably connected to the sealing part 703. The liquid guiding part 704 is composed of a circular shell and a cylindrical shell that are fixedly connected to each other. Hydraulic oil is stored between the liquid guiding part 704 and the sealing part 703. The circular ring inside the sealing part 703 is fixedly connected to the material guiding part 101, and the circular ring inside the sealing part 703 is in limited and sealed rotational fit with the circular shell inside the liquid guiding part 704. A sealing part 705 is limited and sealed and slidably connected to the liquid guiding part 704. The sealing part 705 is slidably connected in the cylindrical shell inside the liquid guiding part 704. The side of the cylindrical shell inside the liquid guiding part 704 close to the center of the circular shell is not sealed with the sealing part 705. The sealing part 705 is fixedly connected to the connecting pipe 701. When the sealing part 705 slides inside the liquid guiding part 704, it controls the distance between the connecting pipe 701 and the outside of the material guiding part 101.

[0054] As Figures 9-11 shown, the connecting pipe 701 is provided with a transverse linear array of air inlets. A first pressure relief valve 801 is fixedly connected to each air inlet in the transverse linear array on the connecting pipe 701. The connecting pipe 701 communicates with the third cavity 1042 through the air inlets in its linear array. After the pressure in the third cavity 1042 exceeds the threshold value of the first pressure relief valve 801, the first pressure relief valve 801 opens, so that the gas in the third cavity 1042 enters the connecting pipe 701 through the air inlets on it. The material guiding part 101 is provided with front and rear symmetric and transverse linear array of air outlets. A second pressure relief valve 803 is arranged at each of the front and rear symmetric and transverse linear array of air outlets in the material guiding part 101. The connecting pipe 701 communicates with the material guiding cavity 1011 through the air guiding cavity 802 and the symmetric and linear array of air outlets on the material guiding part 101. After the pressure in the air guiding cavity 802 exceeds the threshold value of the second pressure relief valve 803, the gas in the air guiding cavity 802 is ejected through the air outlets in the material guiding part 101.

[0055] Before transporting the granular raw materials, the staff connects the liquid outlet of the external liquid supply device to the sealing part 703.

[0056] During the process of conveying granular raw materials, when the rotating rod 1092 moves along the material guiding shell 106 through the inflation of the elastic airbag 108 and the contraction of exhaust, under the action of the inclined rod on the outer side of the rotating rod 1092, the rotating rod 1092 moves and rotates at the same time, so as to stir the surrounding granular raw materials. On the one hand, it destroys the structure composed of granular raw materials and avoids the generation of bridging phenomenon. On the other hand, it crushes the caked granular raw materials to prevent the caked particles from blocking in the feeding part 102, thereby reducing the feeding efficiency of the screw conveyor 104.

[0057] When it is necessary to clean the screw conveyor 104, the telescopic parts of all the third driving parts 603 protrude and contact the outer side of the screw conveyor 104. During the continuous rotation of the screw conveyor 104, all the third driving parts 603 and the sliding frame 503 move horizontally to the left, so that the sliding frame 503 drives the sliding rod 602 to move (the adjacent tension springs are stretched during the movement of the sliding rod 602). During the process that the telescopic part of the third driving part 603 contacts the outer side of the screw conveyor 104, it cleans the screw conveyor 104, so as to realize the treatment of the sticky substances. After the cleaning is completed, the telescopic parts of all the third driving parts 603 can be withdrawn. After the telescopic parts of all the third driving parts 603 are withdrawn, they no longer contact the screw conveyor 104, and under the action of the adjacent tension springs of the sliding rod 602, it drives the sliding rod 602 and all the third driving parts 603 to reset and move.

[0058] Before being put into the screw conveyor, the granular raw materials will also be fragmented or even powdered under the influence of conveying or other steps, and the fragmentation degree of the granular raw materials is different, and the amount of powder generated is also different. Therefore, there will be a problem of excessive dust accumulation in the screw conveyor. When there is excessive dust accumulation in the screw conveyor, it will not only aggravate the wear of the parts in the screw conveyor, but also reduce the discharge quality of the granular raw materials.

[0059] To solve the above problems, the present invention adopts a method of real-time monitoring of the dust amount in the screw conveyor. When there is too much dust in the screw conveyor, the feeding in the screw conveyor is stopped, and the treatment of the dust in the screw conveyor is strengthened.

[0060] When the dust detection module detects that there is too much dust in the material guiding cavity 1011, the telescopic part of the second driving part 301 pushes the fixing ring 302 until the arc-shaped block 303 no longer contacts the second air guiding shell 202. The second air guiding shell 202 moves to the left under the action of the adjacent springs, so that the second air guiding shell 202 is communicated with the second air holes arranged in an annular array on the screw conveyor 104. Therefore, the gas in the second air guiding shell 202 can continuously enter the third cavity 1042.

[0061] When there is too much dust in the material guiding cavity 1011, the output shaft of the first driving member 105 drives the spiral feeding member 104 to rotate in the reverse direction. Subsequently, a hydraulic oil supply device supplies hydraulic oil into the sealing member 703, thereby increasing the pressure in the sealing member 703 and the liquid guiding member 704, causing the sealing member 705 to drive the connecting pipe 701, all the sliding plates 702 and their accessory parts to slide towards the side close to the inner wall of the material guiding member 101. During the process of all the sliding plates 702 sliding out along the spiral feeding member 104, the surrounding granular raw materials are shoveled up, so that the granular raw materials are temporarily not in contact with the granular raw materials at the bottom of the material guiding cavity 1011, and the granular raw materials and powder at the bottom of the material guiding cavity 1011 are exposed in the material guiding cavity 1011.

[0062] During the process of the second air guiding shell 202 supplying air into the third cavity 1042, the pressure in the third cavity 1042 continuously increases. When the pressure in the third cavity 1042 exceeds the threshold values of all the first pressure relief valves 801 (when the gas is lower than the threshold values of the first pressure relief valves 801, the first pressure relief valves 801 remain closed), the gas in the third cavity 1042 enters the connecting pipe 701 through all the air inlets on the connecting pipe 701. Under the action of the connection between the connecting pipe 701 and the air guiding cavity 802, the gas enters the air guiding cavity 802 and continues to accumulate pressure therein. When the pressure in the air guiding cavity 802 exceeds the threshold values of all the second pressure relief valves 803 (when the pressure is lower than the threshold values of the second pressure relief valves 803, the second pressure relief valves 803 remain closed), the gas enters the material guiding cavity 1011 through all the air outlets on the lower side in the material guiding member 101, blowing the powder at the bottom of the material guiding cavity 1011 upwards, so that the powder deposited at the bottom of the material guiding cavity 1011 can be exposed in the material guiding cavity 1011 and be extracted by the air extraction member 504. Through the above description, while no more materials are fed, the effect of powder extraction is enhanced.

[0063] When the dust detection module detects that the dust amount in the material guiding cavity 1011 is normal, the telescopic part of the second driving member 301 pushes the fixing ring 302 until the arc-shaped block 303 contacts the second air guiding shell 202 again ( Figure 5 in the state shown in), and then the first driving member 105 drives the spiral feeding member 104 to rotate forward, thereby resuming the conveying of the granular raw materials.

[0064] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, those skilled in the art should understand that various changes in form and details can be made to the present disclosure without departing from the spirit and scope of the present disclosure.
