Description

Technical Field

[0002] When brewing liquor, in order to promote fermentation and improve brewing efficiency and other factors, a crushing equipment is required to crush the raw materials for brewing.

[0003] Chinese Patent CN213376882U discloses a material crushing device for brewing liquor. This device drives a rolling mechanism and a crushing mechanism by a motor to crush raw materials, and discharges the raw materials that have been crushed in the discharge cylinder through a spiral pushing rod. However, some raw materials for brewing will go through processes such as steaming before crushing, so that these raw materials contain moisture. After the raw materials containing moisture are crushed and fall into the discharge cylinder, they will be concentrated and squeezed towards the discharge port under the pushing of the spiral pushing rod. This causes the raw materials containing moisture to agglomerate under the pushing of the spiral pushing rod, resulting in the influence on the circulation of oxygen and fermentation liquid during the subsequent fermentation process, thus affecting the fermentation efficiency.

Specific embodiments

[0033] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-8, a raw material crushing device, a crushing method and a liquor processing technology, including a machine body 1, characterized in that: a crushing mechanism 2 and a discharging mechanism 3 are arranged on the machine body 1. The crushing mechanism 2 includes a crushing chamber 21 for crushing raw materials. Above the crushing chamber 21, a feed hopper 22 is installed. The raw materials enter the crushing chamber 21 through the feed hopper 22. A pair of transmission shafts 23 are installed in the crushing chamber 21. A number of crushing knife groups 24 are connected to the transmission shafts 23. The transmission shafts 23 can drive the crushing knife groups 24 to rotate to crush the raw materials. The discharging mechanism 3 includes a discharging hopper 31, a screening component 4, a transmission component 5 and a scraping component 6. The discharging hopper 31 is connected below the crushing chamber 21. The screening component 4 includes a sieve plate frame 41 and an arc sieve plate 42. The sieve plate frame 41 is installed on the upper part of the discharging hopper 31. The arc sieve plate 42 is installed in the sieve plate frame 41. The transmission component 5 is arranged between the transmission shaft 23 and the sieve plate frame 41. When the transmission shaft 23 rotates, it can drive the transmission component 5, so that the transmission component 5 drives the sieve plate frame 41 to reciprocate in the discharging hopper 31. The scraping component 6 includes a scraping plate 61, a driving rod 64 and a sliding part 65. The scraping plate 61 is installed on the sieve plate frame 41 and is located in the arc sieve plate 42. The driving rod 64 is installed outside the discharging hopper 31, and the driving rod 64 is matched with the transmission component 5. When the transmission component 5 drives the sieve plate frame 41, it can synchronously drive the driving rod 64 to rotate. The sliding part 65 is assembled on the driving rod 64. One side of the sliding part 65 is connected to the scraping plate 61. When the driving rod 64 rotates, it drives the sliding part 65 to drive the scraping plate 61 to reciprocate and scrape in the arc sieve plate 42.

[0035] Among them, during use, first start the device, then pour the raw materials to be crushed into the feed hopper 22. The raw materials enter the crushing chamber 21 through the feed hopper 22. At this time, a pair of transmission shafts 23 in the crushing chamber 21 drive the upper crushing cutter group 24 to rotate, crushing the raw materials falling into the crushing chamber 21. After being crushed by the crushing mechanism 2, the crushed raw materials will enter the discharge hopper 31. Among them, initially, the sieve plate frame 41 is located on the side of the discharge hopper 31 away from the drive rod 64. The sliding member 65 drives the cleaning scraper 61 to stop at one end of the arc-shaped sieve plate 42 close to the transmission assembly 5. As the transmission shaft 23 rotates, it drives the transmission assembly 5 to operate. While driving the sieve plate frame 41 to move towards the other side of the discharge hopper 31, the transmission assembly 5 also drives the drive rod 64 to rotate, causing the sliding member 65 to drive the cleaning scraper 61 to move towards the other end of the arc-shaped sieve. When the sieve plate frame 41 moves to the other side of the discharge hopper 31, the transmission assembly 5 drives the sieve plate frame 41 to return and restore to its original position, thus performing a reciprocating motion in the discharge hopper 31. During the reciprocating motion of the sieve plate frame 41, the raw materials crushed by the crushing mechanism 2 will fall onto the reciprocating arc-shaped sieve plate 42. The reciprocating arc-shaped sieve plate 42 shakes the crushed raw materials on it, preventing the crushed raw materials from caking due to moisture. At the same time, the arc-shaped sieve plate 42 also screens these raw materials, enabling the raw materials that meet the crushing requirements to pass through the arc-shaped sieve plate 42 and be discharged from the discharge hopper 31, while the large pieces of raw materials will remain on the arc-shaped sieve plate 42. And because the raw materials are moist, some of the crushed raw materials will adhere to the arc-shaped sieve plate 42. At the same time, the drive rod 64 drives the sliding member 65 to drive the cleaning scraper 61 to move towards the other end of the arc-shaped sieve plate 42 first. During the movement, the cleaning scraper 61 cleans the arc-shaped sieve plate 42, pushing the raw materials remaining on the arc-shaped sieve plate 42 out of the arc-shaped sieve plate 42. During this process, the transmission assembly 5 will drive the sieve plate frame 41 to perform multiple reciprocating motions. When the sieve plate frame 41 moves, the cleaning scraper 61 installed on the sieve plate frame 41 will move in the same direction as the sieve plate frame 41 and extend and contract on the sliding member 65 to ensure that the cleaning scraper 61 can operate normally on the arc-shaped sieve plate 42. When the drive rod 64 drives the cleaning scraper 61 to move to the other end of the arc-shaped sieve plate 42, as the drive rod 64 continues to rotate, the sliding member 65 will drive the cleaning scraper 61 to start returning to its original position, causing the cleaning scraper 61 to scrape the arc-shaped sieve plate 42 in the reverse direction, cleaning the arc-shaped sieve plate 42 from another angle, thereby improving the cleaning effect and pushing the newly aggregated raw materials on the arc-shaped sieve plate 42 to move in the same direction and be discharged from the end of the arc-shaped sieve plate 42. This process is repeated until the production work is completed, and then the operation of the device is stopped.

[0036] The difference from the above embodiment is that the upper side of the discharge hopper 31 is fixedly connected to the lower side of the crushing chamber 21. Sliding grooves 311 are formed at both ends of the discharge hopper 31, and the sliding grooves 311 are located in the upper part of the discharge hopper 31. A notch 312 is formed on one side of the discharge hopper 31, and the notch 312 is located above the sliding groove 311. A partition 32 is fixedly connected to both ends inside the discharge hopper 31. The partition 32 separates side outlets 321 at both ends inside the discharge hopper 31. The two ends of the arc-shaped sieve plate 42 respectively correspond to the side outlets 321 at both ends of the discharge hopper 31.

[0037] Among them, when the cleaning scraper 61 moves to the end of the arc-shaped sieve plate 42, the cleaning scraper 61 will push the raw material fragments scraped from the arc-shaped sieve plate 42 into the side outlet 321, so as to separate the raw materials that meet the crushing requirements from those that do not meet the crushing requirements, and it is possible to collect these two kinds of raw materials separately, thus facilitating subsequent processing.

[0038] The difference from the above embodiment is that both ends of the sieve plate frame 41 are slidably installed in the sliding grooves 311. The arc-shaped sieve plate 42 is fixedly installed in the sieve plate frame 41. A number of through holes are formed on the arc-shaped sieve plate 42. There are gaps corresponding to the side outlets 321 between the two ends of the arc-shaped sieve plate 42 and the two ends of the sieve plate frame 41. Sealing plates 43 are slidably installed on both ends of the sieve plate frame 41. One side of the sealing plate 43 close to the sliding groove 311 is fixedly connected to one end of a support spring 44. A baffle is fixed on the end of the sieve plate frame 41. The other end of the support spring 44 is fixedly connected to the baffle of the sieve plate frame 41. The support spring 44 pushes the sealing plate 43 to block both ends of the arc-shaped sieve plate 42. A connecting block 45 is fixedly connected to the outside of one end of the sieve plate frame 41 close to the transmission assembly 5, and the connecting block 45 is located outside the discharge hopper 31.

[0039] Among them, when the transmission component 5 drives the sieve plate frame 41, the sieve plate frame 41 drives the components thereon to reciprocate in the sliding groove 311. While the raw materials crushed by the crushing mechanism 2 fall onto the arc sieve plate 42 and are shaken loose, the raw materials that meet the crushing requirements will pass through the through holes of the arc sieve plate 42 and thus be discharged from the discharge hopper 31, while the raw materials that do not meet the crushing requirements will remain on the arc sieve plate 42. And initially, the blocking plate 43 at the docking end of the cleaning scraper 61 moves towards the sliding groove 311 under the push of the cleaning scraper 61, thereby opening this end of the arc sieve plate 42 and compressing the support spring 44 on the blocking plate 43, enabling the cleaning scraper 61 to push the scraped raw materials into the side outlet 321 at this end. And the other blocking plate 43 continues to block the arc sieve plate 42. When the cleaning scraper 61 leaves this end and moves towards the other end of the arc sieve plate 42, the compressed support spring 44 restores its deformation and pushes the blocking plate 43 to block this end of the arc sieve plate 42. When the cleaning scraper 61 reaches the other end of the arc sieve plate 42, it will push the blocking plate 43 at the other end to open the other end of the arc sieve plate 42, facilitating the discharge of the cleaning scraper 61. When the cleaning scraper 61 is between the two blocking plates 43, both ends of the arc sieve plate 42 are blocked by the blocking plates 43, so that the raw materials falling from the crushing chamber 21 will not fall into the side outlet 321 during the process of being shaken and screened by the sieve plate frame 41.

[0040] The difference from the above embodiment is that the transmission component 5 includes a mounting seat 51 and a long connecting rod 54. The mounting seat 51 is fixedly installed on the outside of the discharge hopper 31, and the mounting seat 51 is located below the connecting block 45. A rotating shaft 52 is rotatably installed at the upper end of the mounting seat 51. One end of the rotating shaft 52 facing the connecting block 45 is fixedly connected with an eccentric wheel 53. One side of the eccentric wheel 53 is fixedly connected with an eccentric shaft 531. The lower end of the long connecting rod 54 is rotatably connected with the lower end of the mounting seat 51. A linkage plate 55 is fixedly connected to the long connecting rod 54. An arc-shaped groove 551 is formed on the side of the linkage plate 55 facing the eccentric shaft 531. The arc-shaped groove 551 corresponds to the eccentric wheel 53. The eccentric shaft 531 is located in the arc-shaped groove 551. When the eccentric wheel 53 rotates, it drives the eccentric shaft 531 to move in the arc-shaped groove 551, thereby driving the linkage plate 55 to drive the long connecting rod 54 to swing reciprocally. The upper end of the long connecting rod 54 is rotatably connected with the lower end of the short connecting rod 56, and the upper end of the short connecting rod 56 is rotatably connected with the connecting block 45.

[0041] Among them, when the rotating shaft 52 rotates, the rotating rotating shaft 52 drives the eccentric wheel 53 to rotate synchronously. As the eccentric wheel 53 rotates, through the cooperation of its eccentric shaft 531 and the arc-shaped groove 551, the linkage plate 55 pulls the long connecting rod 54 to swing back and forth on the eccentric wheel 53. The reciprocally swinging long connecting rod 54, in cooperation with the short connecting rod 56, drives the sieve plate frame 41 to perform a linear reciprocating motion through the connecting block 45.

[0042] The difference from the above embodiment is that both ends of the cleaning scraper 61 are fixedly connected with sliders 62. The sliders 62 are slidably installed on the frame of the sieve plate frame 41. The lower end of the cleaning scraper 61 is arc-shaped and fits the upper surface of the arc-shaped sieve plate 42. A connecting plate 63 is fixedly connected to the slider 62 on the side of the cleaning scraper 61 close to the driving rod 64, and an extension groove 631 is formed in the connecting plate 63.

[0043] Wherein, when the cleaning scraper 61 reaches the end of the arc-shaped sieve plate 42, the slider 62 will contact the blocking plate 43 one step ahead of the cleaning scraper 61, so as to open the blocking plate 43 blocking the end of the arc-shaped sieve plate 42.

[0044] The difference from the above embodiment is that the driving rod 64 is a reciprocating lead screw. The driving rod 64 is rotatably installed outside the discharge hopper 31. The sliding member 65 is assembled on the threaded section of the driving rod 64. When the driving rod 64 rotates, it can drive the sliding member 65 thereon to reciprocate. A C-shaped plate 66 is fixedly connected to the side of the sliding member 65 facing the discharge hopper 31. The C-shaped plate 66 passes through the notch 312 and is slidably connected to the connecting plate 63 through a sliding rod. The sliding rod of the C-shaped plate 66 is located in the extension groove 631.

[0045] Wherein, when the reciprocating lead screw rotates, the sliding member 65 can move reversely to the other end when reaching one end of the reciprocating lead screw through the thread groove thereon, so as to realize the reciprocating movement of the sliding member 65. When the driving rod 64 drives the sliding member 65 to move, the sliding member 65 makes the cleaning scraper 61 move synchronously on the arc-shaped sieve plate 42 through the cooperation of the C-shaped plate 66 and the connecting plate 63. And when the sieve plate frame 41 reciprocates, the connecting plate 63 will be retracted into the groove of the C-shaped plate 66 under the drive of the sieve plate frame 41, or the connecting plate 63 will protrude from the groove of the C-shaped plate 66 under the drive of the sieve plate frame 41 to adapt to the displacement change of the cleaning scraper 61 along with the sieve plate frame 41.

[0046] The difference from the above embodiment is that the crushing mechanism further includes a driving motor 25. The driving motor 25 is fixedly installed on the machine body 1. The output shaft of the driving motor 25 is coaxially and fixedly connected to one end of the transmission shaft 23 on the side close to the driving rod 64. Transmission gears 231 are coaxially and fixedly connected to the other ends of the two transmission shafts 23, and the two transmission gears 231 mesh with each other.

[0047] Wherein, after the equipment is started, the driving motor 25 drives the connected transmission shaft 23 to rotate. This rotating shaft drives the other transmission shaft 23 to rotate through the cooperation between the two transmission gears 231, so that the rotating shaft drives the crushing knife group 24 thereon to crush the raw materials.

[0048] The difference from the above embodiment is that at the other end of the rotating shaft 52, at the end of the transmission shaft 23 not connected to the driving motor 25, and at one end of the driving rod 64 close to the transmission assembly 5, belt pulleys 7 are coaxially and fixedly connected. A transmission belt 8 is connected between the belt pulley 7 on the rotating shaft 52 and the belt pulley 7 on the transmission shaft 23 and between the belt pulley 7 on the driving rod 64 respectively.

[0049] Among them, when the transmission shaft 23 drives the rotating shaft 52 to rotate through the transmission belt 8, the rotating rotating shaft 52 drives the driving rod 64 to rotate through another transmission belt 8.

[0050] The present invention also provides a crushing method, which uses a raw material crushing device.

[0051] The present invention also provides a white liquor processing technology, which uses a raw material crushing device;

[0052] It includes the following steps:

[0053] S1. First, start the device. The driving motor 25 drives the crushing cutter group 24 to rotate in the crushing chamber 21. After the device is started, pour the raw material to be crushed into the feed hopper 22.

[0054] S2. After the raw material is poured into the feed hopper 22, the raw material enters the crushing chamber 21 through the feed hopper 22 and is crushed by the rotating crushing cutter group 24.

[0055] S3. The crushed raw material enters the discharge hopper 31 from the crushing chamber 21. The crushed raw material falls onto the arc-shaped sieve plate 42. The transmission assembly 5 drives the sieve plate frame 41 to drive the arc-shaped sieve plate 42 to reciprocate in the discharge hopper 31, so that the arc-shaped sieve plate 42 shakes and screens the crushed raw material during the movement.

[0056] S4. During the screening process of the arc-shaped sieve plate 42, the driving rod 64 drives the cleaning scraper 61 to reciprocate on the arc-shaped sieve plate 42, thereby scraping off the raw material remaining on the arc-shaped sieve plate 42, and opening the blocking plate 43 at the end of the arc-shaped sieve plate 42 to discharge the scraped raw material into the side outlet 321.

[0057] S5. Separate the raw materials discharged from the side outlet 321 and the raw materials discharged from the middle of the discharge hopper 31 for separate collection, so as to facilitate the next process.

[0058] Working principle: When in use, first start the device. The driving motor 25 drives the connected transmission shaft 23 to rotate. Through the cooperation between the two transmission gears 231 on this rotating shaft, another transmission shaft 23 is driven to rotate, so that the rotating shaft drives the crushing knife group 24 on it to rotate. Then, the raw materials to be crushed are poured into the feed hopper 22, and the raw materials enter the crushing chamber 21 through the feed hopper 22. The rotating crushing knife group 24 crushes the raw materials falling into the crushing chamber 21. After being crushed by the crushing mechanism 2, the crushed raw materials will enter the discharge hopper 31. Among them, initially, the sieve plate frame 41 is located on the side of the discharge hopper 31 far from the driving rod 64. The sliding member 65 stops with the cleaning scraper 61 at one end of the arc-shaped sieve plate 42 close to the transmission assembly 5. As the transmission shaft 23 drives the transmission assembly 5 to operate through the transmission belt 8, while the transmission assembly 5 drives the sieve plate frame 41 to move towards the other side of the discharge hopper 31, it also drives the driving rod 64 to rotate, causing the sliding member 65 to drive the cleaning scraper 61 to move towards the other end of the arc-shaped sieve. When the sieve plate frame 41 moves to the other side of the discharge hopper 31, the transmission assembly 5 drives the sieve plate frame 41 to return and restore to its original position, thus making a reciprocating motion in the discharge hopper 31. During the reciprocating motion of the sieve plate frame 41, the raw materials crushed by the crushing mechanism 2 will fall onto the reciprocating arc-shaped sieve plate 42. The reciprocating arc-shaped sieve plate 42 shakes loose the crushed raw materials on it, preventing the crushed raw materials from caking due to moisture. At the same time, the arc-shaped sieve plate 42 also screens these raw materials, allowing the raw materials that meet the crushing requirements to pass through the arc-shaped sieve plate 42 and be discharged from the discharge hopper 31, while the large pieces of raw materials will remain on the arc-shaped sieve plate 42. And because the raw materials are moist, some of the crushed raw materials will adhere to the arc-shaped sieve plate 42;

[0059] Meanwhile, the driving rod 64 drives the sliding member 65 to drive the cleaning scraper 61 to move towards the other end of the arc-shaped sieve plate 42 first. During the movement of the cleaning scraper 61, the arc-shaped sieve plate 42 is cleaned, and the raw materials remaining on the arc-shaped sieve plate 42 are pushed out of the arc-shaped sieve plate 42. During this process, the transmission assembly 5 drives the sieve plate frame 41 to perform multiple reciprocating motions. When the sieve plate frame 41 moves, the cleaning scraper 61 installed on the sieve plate frame 41 will move in the same direction as the sieve plate frame 41 and extend and contract on the sliding member 65 to ensure that the cleaning scraper 61 can operate normally on the arc-shaped sieve plate 42. When the driving rod 64 drives the cleaning scraper 61 to move to the other end of the arc-shaped sieve plate 42, as the driving rod 64 continues to rotate, the sliding member 65 will drive the cleaning scraper 61 to start the reverse stroke and return to the original position, so that the cleaning scraper 61 scrapes the arc-shaped sieve plate 42 in the reverse direction, cleaning the arc-shaped sieve plate 42 from another angle, thereby improving the cleaning effect, and pushing the newly aggregated raw materials on the arc-shaped sieve plate 42 to move in the same direction and discharge from the end of the arc-shaped sieve plate 42. Among them, initially, the blocking plate 43 at the docking end of the cleaning scraper 61 moves towards the direction of the sliding groove 311 under the push of the cleaning scraper 61, thereby opening this end of the arc-shaped sieve plate 42 and compressing the support spring 44 on the blocking plate 43, so that the cleaning scraper 61 can push the scraped raw materials into the side outlet 321 at this end, while the other blocking plate 43 continues to block the arc-shaped sieve plate 42. When the cleaning scraper 61 leaves this end and moves towards the other end of the arc-shaped sieve plate 42, the compressed support spring 44 resumes deformation and pushes the blocking plate 43 to block this end of the arc-shaped sieve plate 42. When the cleaning scraper 61 reaches the other end of the arc-shaped sieve plate 42, it will push the blocking plate 43 at the other end to open the other end of the arc-shaped sieve plate 42 to facilitate the discharge of the cleaning scraper 61. When the cleaning scraper 61 is between the two blocking plates 43, both ends of the arc-shaped sieve plate 42 are blocked by the blocking plates 43, so that the raw materials falling from the crushing chamber 21 will not fall into the side outlet 321 during the process of being shaken and screened by the sieve plate frame 41. After repeating this process until the production work is completed, the operation of the equipment is stopped.
