Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] An integrated device for low-temperature ultrafine pulverization and classification of konjac disclosed by the present invention is mainly applied to the scenario where the current low-temperature pulverizer cannot achieve continuous and cyclic processing of konjac ultrafine powder.

[0032] Referring to Figure 1-7 , an integrated device for low-temperature ultrafine pulverization and classification of konjac includes a bottom plate 1, a low-temperature pulverization box 2, an air-screen crushing box 3 and a feeding tube 4. The low-temperature pulverization box 2, the air-screen crushing box 3 and the feeding tube 4 are all located above the bottom plate 1. The air-screen crushing box 3 and the feeding tube 4 are respectively located on both sides of the low-temperature pulverization box 2. A cold-chamber conveying pipe 5 is provided between the low-temperature pulverization box 2 and the air-screen crushing box 3, and a screening and transfer pipe 6 is provided between the low-temperature pulverization box 2 and the feeding tube 4. It further includes:

[0033] The primary screening and crushing module 7 is arranged on the air-screening and crushing box 3, and includes a vertical disk 701, a cover plate 702 and an air supply pipe, and is used for the primary crushing and feeding of konjac granules;

[0034] The low-temperature crushing module 8 is arranged on the low-temperature crushing box 2, and includes a crushing chamber 801, a rotating disk 802 and a plurality of crushing frames 803, and is used for the ultrafine crushing of konjac powder;

[0035] The sequential feeding module 9 is arranged on the feeding cylinder 4, and includes a feeding bin 901, a shaft rod 902 and a spiral feeding blade 903, and is used for the feeding of konjac ultrafine powder and the cold air reflux cycle.

[0036] Specifically, the device adopts a form of hierarchical crushing integration. Konjac granules will be initially crushed into powder, and then ultrafinely crushed into ultrafine powder products at low temperature. The whole process uses air flow to realize feeding, discharging and screening. The process is continuous and can be continuously cycled, effectively solving the drawback of needing to stop the machine for feeding, and improving the overall processing efficiency of konjac ultrafine powder.

[0037] Refer to Figure 1 、 Figure 3 and Figure 4 , in a preferred embodiment, the primary screening and crushing module 7 further includes a frame 704. The frame 704 is located on the upper side of the bottom plate 1 and is connected by bolts. A crushing motor 705 is connected to the frame 704 by bolts. The output end of the crushing motor 705 is connected to a short shaft through a coupling. The vertical disk 701 is rotatably connected inside the primary screening and crushing box through a bearing. The other end of the short shaft passes through the primary screening and crushing box and is connected to the vertical disk 701 by bolts. And the primary screening and crushing box and the cover plate 702 are rotatably connected by hinges. Crushing rods 706 are arranged on both opposite sides of the vertical disk 701 and the cover plate 702; A feeding bin 707 and an air inlet are arranged on the primary screening and crushing box. An air-screening net 708 is arranged on the air inlet. A blowing seat 709 is connected to the air inlet position of the primary screening and crushing box by bolts. The blowing seat 709 is communicated with the inside of the primary screening and grinding box. The feeding pipe 703 is located above the blowing seat 709. The upper and lower ends of the feeding pipe 703 are respectively communicated with the cold chamber conveying pipe 5 and the primary screening and crushing box. And an air conveying pipe 710 is connected to the blowing seat 709 by bolts. The other end of the air conveying pipe 710 is connected to an air conveying interface 711 by bolts. An air conveying regulating valve 712 is arranged on the air conveying pipe 710.

[0038] Specifically, the broken particles are added from the feeding bin 707. The crushing motor 705 drives the vertical disk 701 to rotate at a high speed. The broken particles are crushed into powder by the crushing rod 706 between the vertical disk 701 and the cover plate 702. The external blower is connected to the air supply interface 711, and the air flow blows out from the air sieve mesh 708 through the air delivery pipe 710. An air flow is formed in the sealed air sieve crushing box 3. The air flow direction is: the air sieve crushing box 3 flows through the feeding pipe 703 and enters the cold chamber material conveying pipe 5. The qualified broken powder enters the cold chamber material conveying pipe 5 along with the air flow from the feeding pipe 703.

[0039] In a specific application scenario, the primary screening and crushing module 7 is applicable to the initial crushing of konjac broken particles into powder. That is, the primary screening and crushing module 7 uses a vertically rotating disk 701, and the broken particles are crushed into powder by the crushing rod 706 on the vertical disk 701 and the cover plate 702. And by means of blowing and feeding, the qualified broken powder is continuously fed into the low-temperature pulverizing box 2. This process realizes the effects of primary crushing, screening broken powder and continuous feeding, ensures the continuity of konjac ultrafine powder production, and improves the overall production efficiency. The screening of the broken powder can be controlled by adjusting the blowing rate: adjusting the air supply regulating valve 712 changes the wind speed rate entering the air delivery pipe 710, thereby controlling the wind force entering the air sieve crushing box 3. The greater the wind force, the larger the broken powder particles entering the cold chamber material conveying pipe 5, and vice versa.

[0040] Refer to Figure 1 、 Figure 3 and Figure 5 In a preferred embodiment, the low-temperature pulverizing box 2 is provided with a feed inlet 10 and a discharge outlet 11. The discharge outlet 11 is located below the screening and transfer pipe 6, and the feed inlet 10 is bolted to the cold chamber material conveying pipe 5. The other end of the cold chamber material conveying pipe 5 is bolted to a cold air interface 12. The lower side of the low-temperature pulverizing box 2 is bolted to a support platform 13, and the support platform 13 is bolted to the upper side of the bottom plate 1.

[0041] Specifically, the cold air interface 12 of the cold chamber material conveying pipe 5 is connected to an external refrigerating machine, and cold air is continuously fed into the cold chamber material conveying pipe 5. The cold air is in a continuous circulation state in the cold chamber material conveying pipe 5, which is convenient for the feeding operation of the broken powder after primary screening and crushing. At the same time, the cold air is used to accompany the feeding of the broken powder in the cold chamber material conveying pipe 5, which can quickly cool the broken powder during the feeding process and is convenient for subsequent low-temperature ultrafine pulverizing operation.

[0042] Refer to Figure 1 and Figure 5, in a preferred embodiment, the low-temperature crushing module 8 further includes a plurality of movable mounting ports 804. The plurality of movable mounting ports 804 are circumferentially and equidistantly distributed outside the rotating disk 802. The rotating disk 802 is rotatably connected inside the low-temperature crushing box 2 through a bearing. A crushing motor 807 is provided below the low-temperature crushing box 2. The crushing motor 807 is bolted to the support platform 13. The output end of the crushing motor 807 is connected to the rotating disk 802 through a coupling. And a plurality of crushing frames 803 are respectively rotatably connected inside the plurality of movable mounting ports 804 through bearings. A plurality of crushing rods 805 are provided on the plurality of crushing frames 803, and barbs 806 are provided on the crushing rods 805.

[0043] Specifically, the crushing motor 807 drives the rotating disk 802 to rotate at a high speed, and the crushing rods 805 perform ultrafine crushing on the pulverized powder in the crushing chamber 801; the air flow in the crushing chamber 801 will enter the screening and transfer pipe 6 from the discharge port 11. During this process, the ultrafine powder that meets the specifications will be carried up by the air flow and separated from the crushing chamber 801 to achieve transfer and discharge.

[0044] In a specific application scenario, the low-temperature crushing module 8 is applicable to the further crushing of the pulverized powder in the low-temperature crushing box 2 to form ultrafine powder. That is, the low-temperature crushing module 8 uses the rotating disk 802 that rotates at a high speed to drive the crushing rods 805 to perform ultrafine crushing on the pulverized powder in the crushing chamber 801, so that the pulverized powder is processed into ultrafine powder. At the same time, the air flow in the crushing chamber 801 is used to screen the ultrafine powder to achieve screening and discharging of the ultrafine powder; the crushing frame 803 is movably connected to the rotating disk 802. During the rotation and crushing process, it will be impacted by the air flow and the pulverized powder in the crushing chamber 801 and change its state, so that it rotates around the rotating disk 802 while rotating itself, further improving the contact with the pulverized powder in the chamber; the cold air circulates in the crushing chamber 801 to form an air flow, driving the pulverized powder to suspend, increasing the contact effect between the pulverized powder and the crushing rods 805; the barbs 806 provided on the crushing rods 805 can further increase the crushing effect.

[0045] Refer to Figure 1 , Figure 2 and Figure 6 , in a preferred embodiment, a vertical frame 15 is bolted to the outside of the feeding cylinder 4. The vertical frame 15 is bolted to the upper side of the bottom plate 1. An output motor 16 is provided at the top of the vertical frame 15. And an output stage control assembly 14 is provided between the screening and transfer pipe 6 and the low-temperature crushing box 2.

[0046] Refer to Figure 1 and Figure 6In a preferred embodiment, the continuous unloading module 9 also includes a top bin 904, the top bin 904 is located at the upper end of the unloading barrel 4, the unloading bin 901 is located at the lower end of the unloading barrel 4, the shaft 902 is located inside the top bin 904 and the unloading barrel 4, the output end of the unloading motor 16 is connected to the top end of the shaft 902 through a coupling, the bolt unloading blade is located outside the shaft 902, and the top bin 904 is connected to a return pipe 905 by bolts, and the lower end of the return pipe 905 is connected to an external pipe interface 906 by bolts.

[0047] Specifically, during the ultrafine powder transportation period: the upward airflow drives the ultrafine powder into the screening transfer pipe 6, and the airflow entering the screening transfer pipe 6 can be adjusted by changing the air guide control valve, so as to achieve the effect of regulating the screening of the ultrafine powder, that is, when the micro powder particles are small, the airflow in the air guide pipe 1403 is increased, and the upward airflow in the screening transfer pipe 6 will be reduced accordingly, so that the airflow can only carry small particles of ultrafine powder;

[0048] In a specific application scenario, the discharge-level regulating component 14 is suitable for regulating the particle size of the discharged ultrafine powder, that is, the discharge-level regulating component 14 uses the air guide regulating valve to regulate the airflow in the air guide pipe 1403, so as to achieve the purpose of changing the size of the airflow in the screening transfer pipe 6, and realize the discharge screening of ultrafine powders of different particle sizes; the regulating box 1401 is used to form a dual-path for the airflow in the low-temperature crushing box 2, and the synchronous adjustment of the two airflows is achieved by changing the size of the airflow in one path, so as to achieve the screening effect of the airflow discharge; the closed-end filter 1402 can filter the ultrafine powder.

[0049] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the discharge-level regulating component 14 includes a regulating box 1401, which is connected to the discharge port 11 of the low-temperature crushing box 2 by bolts, and the regulating box 1401 is connected to the screening transfer pipe 6. A closed-end filter screen 1402 is provided inside the regulating box 1401, and the closed-end filter screen 1402 is located between the outer wall of the screening transfer pipe 6 and the inner wall of the regulating box 1401, and an air guide pipe 1403 is connected to the regulating box 1401 by bolts, and the other end of the air guide pipe 1403 is connected to the reflux pipe 905, and an air guide regulating valve 1404 is provided on the air guide pipe 1403.

[0050] Specifically, the ultrafine powder enters the blanking cylinder 4 through the screening transfer pipe 6. The discharging motor 16 drives the shaft rod 902 to rotate, and the spiral blanking blade 903 continuously rotates in the blanking cylinder 4. The ultrafine powder is accompanied by the impact of cold air on the spiral blanking blade 903. Due to the obstruction of the spiral blanking blade 903, the kinetic energy of the ultrafine powder decreases after impact. At the same time, the spiral blanking blade 903 located below the interface of the screening transfer pipe 6 changes in size, hindering the flow of air, so that the air mostly enters the top bin 904 in an upward flow manner and returns to the external refrigerator through the return pipe 905, while the ultrafine powder in the blanking cylinder 4 realizes blanking along with the rotation of the spiral blanking blade 903;

[0051] In a specific application scenario, the sequential blanking module 9 is applicable to the blanking of ultrafine powder in the blanking cylinder 4 and the reflux cycle of cold air. That is, the sequential blanking module 9 uses the spiral blanking blade 903 with changing specifications to continuously rotate in the blanking cylinder 4, so as to form the separation of solid and gas in the cylinder. The ultrafine powder falls, and the cold air flows upward, thus realizing the blanking of ultrafine powder and the reflux cycle of cold air.

[0052] A method for integrated low-temperature ultrafine grinding and classification of konjac uses an integrated device for low-temperature ultrafine grinding and classification of konjac as described above, and includes the following steps:

[0053] Step 1: The konjac particles after low-temperature treatment are added into the air-screen crushing box 3 and preliminarily crushed by the preliminary screening and crushing module 7 (the particles are added from the feeding bin 707, the crushing motor 705 drives the vertical disk 701 to rotate at a high speed, and the particles are crushed into powder by the crushing rod 706 between the vertical disk 701 and the cover plate 702). The crushed powder that reaches the crushing specification is screened and conveyed into the cold chamber conveying pipe 5 (the external blower is connected to the air supply interface 711, and the air flow blows out from the air-screen mesh 708 through the air conveying pipe 710. An air flow is formed in the sealed air-screen crushing box 3. The air flow direction: the air-screen crushing box 3 flows through the feeding pipe 703 and enters the cold chamber conveying pipe 5. The crushed powder that meets the specification enters the cold chamber conveying pipe 5 along with the air flow), and is cooled in the cold chamber conveying pipe 5 and then sent into the low-temperature grinding box 2 (the cold air interface 12 of the cold chamber conveying pipe 5 is connected to the external refrigerator, and cold air is continuously sent into the cold chamber conveying pipe 5);

[0054] Step 2: The crushed powder is ultrafinely crushed by the low-temperature crushing module 8 in the low-temperature crushing chamber 2 (the crushing motor 807 drives the rotating disk 802 to rotate at a high speed, and the crushing rod 805 ultrafinely crushes the crushed powder in the crushing chamber 801). The ultrafine powder meeting the crushing specifications is transported to the blanking cylinder 4 through the screening and transfer pipe 6 (the air flow in the crushing chamber 801 will enter the screening and transfer pipe 6 from the discharge port 11. During this process, the ultrafine powder meeting the specifications will be lifted by the air flow and separated from the crushing chamber 801 with the air flow to achieve transfer and discharge). During this process, part of the cold air flows back in a cycle (during the transfer of the ultrafine powder: the upward air flow drives the ultrafine powder into the screening and transfer pipe 6. By changing the air guide control valve, the size of the air flow entering the screening and transfer pipe 6 can be adjusted, so as to achieve the effect of screening and regulating the ultrafine powder. That is, when smaller micro-powder particles are required, the air flow in the air guide pipe 1403 is increased, and the upward air flow in the screening and transfer pipe 6 will decrease accordingly. Thus, the air flow can only lift the small-particle ultrafine powder).

[0055] Step 3: The ultrafine powder is assisted in blanking by the sequential blanking module 9 in the blanking cylinder 4 (the ultrafine powder enters the blanking cylinder 4 from the screening and transfer pipe 6. The discharge motor 16 drives the shaft rod 902 to rotate, and the spiral blanking blade 903 continuously rotates in the blanking cylinder 4. The ultrafine powder impacts on the spiral blanking blade 903 along with the impact of the cold air. Due to the obstruction of the spiral blanking blade 903, the kinetic energy of the ultrafine powder decreases after impact. At the same time, the spiral blanking blade 903 below the interface of the screening and transfer pipe 6 changes in size, hindering the flow of the air flow so that the air flow mostly enters the top bin 904 in an upward flow manner and flows back to the external refrigerator through the return pipe 905. The ultrafine powder in the blanking cylinder 4 is blanked along with the rotation of the spiral blanking blade 903), and the cold air enters the return pipe 905 and flows back in a cycle.
