Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to a dry and wet dual-purpose grinding and slurry mill. Background Technology

[0002] In food processing, grinding raw materials such as grains and beans into powders or slurries is a common initial processing step. Traditional grinding mechanisms usually use two grinding discs that rotate in opposite directions to grind wet materials into slurry and dry materials into powder.

[0003] Traditional grinding mechanisms only have a single grinding function. In actual production, dry materials usually need to be ground multiple times to achieve the required fineness, which is a cumbersome process. Moreover, traditional grinding mechanisms lack filtration components, which means that the material needs to be screened separately after each grinding to separate the residue, resulting in an excessively long processing cycle. Furthermore, due to the single function, processing requires the configuration of multiple equipment with different functions, which increases the investment cost. In addition, traditional screening mechanisms drive the material movement through vibration, but lack components for cleaning the screen. During the screening process, large residue particles can easily clog the screen holes, leading to a decrease in screening efficiency. This requires stopping the machine for cleaning, which is time-consuming and labor-intensive, and seriously restricts the efficiency of production and processing.

[0004] In view of this, we propose a dry and wet dual-purpose grinding and pulping machine to solve the existing problems. Summary of the Invention

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1, as Figure 1 - Figure 8 As shown, the present invention proposes a dry and wet dual-purpose grinding and slurry mill, which includes a feeding mechanism 1, an abrasive mechanism 101 installed at the front end of the feeding mechanism 1 for grinding raw materials, a discharge port 102 at the bottom of the abrasive mechanism 101 for discharging the ground product, a separation mechanism 2 installed at the bottom of the feeding mechanism 1 for separating fine powder and residue during grinding, and a drive mechanism 3 installed at the bottom of the separation mechanism 2. The separation mechanism 2 has an internal cavity, in which a first cavity 202 and a second cavity 204 are arranged side by side and connected. The front end of the separation mechanism 2 is provided with an inlet 401 that connects to the first cavity 202. A switching mechanism 6 is installed outside the inlet 401, and a guide plate 5 connected to the outlet 102 is installed on the switching mechanism 6. The switching mechanism 6 is used to switch the guide plate 5 so that the outlet 102 can be connected between the inlet 401 and the outside of the equipment. During grinding, the guide plate 5 is used to connect the outlet 102 to the outside of the equipment. The solid-liquid mixture after grinding by the grinding mechanism 101 is discharged from the outlet 102 and guided to the outside of the equipment by the guide plate 5, and collected by a container. The first chamber 202 is equipped with a filter assembly 8, which in turn is equipped with a sieving mechanism 7. The sieving mechanism 7 is connected to the drive mechanism 3. During grinding, the guide plate 5 connects the discharge port 102 with the feed port 401, so that the ground powdery dry mixture is discharged from the discharge port 102, passes through the guide plate 5, and enters the first chamber 202, where it is filtered by the filter assembly 8. The sieving mechanism is set in the filter assembly 8 to agitate the powdery dry mixture, so that the ground fine powder passes through the filter assembly 8 and is discharged from the first chamber 202. The residue that cannot pass through the filter assembly 8 is driven by the sieving assembly and enters the second chamber 204, from which it is discharged.

[0023] Furthermore, a hopper is provided between the feeding mechanism 1 and the abrasive mechanism 101. The feeding mechanism 1 is provided with a feeding shaft 103. The abrasive mechanism 101 includes a first disc 1011 fixedly connected to the feeding mechanism 1, and a second disc 1012 hinged to the first disc 1011. The front end of the feeding shaft 103 passes through the first disc 1011 and is fixedly connected to a movable grinding disc 104. A stationary grinding disc 105, which is mirror-symmetrical to the movable grinding disc 104, is provided on the second disc 1012. The movable grinding disc 104 and the stationary grinding disc 105 have a grinding gap. The material can be controlled within the grinding gap by adjusting the advancing speed of the feeding shaft 103. The residence time in the grinding process is adjusted to achieve precise control of the grinding fineness. The first disc 1011 and the second disc 1012 are hinged, allowing the second disc 1012 to be opened for easy cleaning of the inside of the disc, as well as the moving grinding disc 104 and the stationary grinding disc 105. The stationary grinding disc 105 is connected to the second disc 1012 via an adjusting shaft, which is threaded to the second disc 1012. This allows the adjusting shaft to be rotated relative to the second disc 1012 to adjust the distance between the second disc 1012 and the first disc 1011, thereby adjusting the distance of the grinding gap and thus the coarseness of the material being ground.

[0024] Furthermore, the drive mechanism 3 includes a base 301 fixedly installed at the bottom of the separation mechanism 2. A drive motor 302, model YL90L-4 single-phase asynchronous motor, is installed inside the base 301. The output end of the drive motor 302 is connected to the feed shaft 103 and the screening mechanism 7 through the transmission assembly. During grinding, the drive motor 302 drives the feed shaft 103 to move only through the transmission assembly. During grinding, the drive motor 302 drives the feed shaft 103 and the screening mechanism 7 to move through the transmission assembly.

[0025] Furthermore, a baffle 203 is provided between the first cavity 202 and the second cavity 204. The end of the first cavity 202 away from the baffle 203 passes through the side wall of the separation mechanism 2 and is provided with a connecting ring 201. A hatch cover 4 is hinged to the side end of the separation mechanism 2. The hatch cover 4 is closed and connected to the connecting ring 201. The feed inlet 401 is provided on the hatch cover 4 and communicates with the first cavity 202 to seal the inner cavity of the separation mechanism 2, thereby preventing impurities from entering.

[0026] Furthermore, the switching mechanism 6 includes side plates 601 installed on the left and right sides outside the feed inlet 401 and a bottom plate 602 installed on the bottom side outside the feed inlet 401. The bottom plate 602 is inclined towards the feed inlet 401 from the outside, and is used to position the guide plate 5 when it connects the discharge outlet 102 and the feed inlet 401, so that the guide plate 5 is inclined towards the feed inlet 401 from the end face of the bottom plate 602, thereby guiding the dry powder mixture from the discharge outlet 102 into the first cavity 202 for filtration and separation during grinding. The two ends of the bottom plate 602 are respectively connected to the side plates 601 on both sides. A rotating shaft is provided between the two side plates 601 and is rotatably connected to the guide plate 5, so that the guide plate 5 can rotate around the side plate 601 to select the connection state. During the adjustment process, one end of the guide plate 5 is always connected to the discharge port 102, so as to guide the ground product to the separation mechanism 2 or the outside of the equipment according to different processing requirements. One end of the rotating shaft passes through the side plate 601 and is connected to a locking mechanism by a thread. The locking mechanism is movable against the side wall of the side plate 601 and is used to lock the guide plate after the adjustment is in place, so as to prevent the guide plate 5 from rotating during the guidance process and causing accidental switching.

[0027] Furthermore, the filter assembly 8 includes a filter cylinder 801 installed inside the first cavity 202. A screen 802 is installed on the outer periphery of the filter cylinder 801. The screen 802 with different mesh sizes can be replaced according to processing requirements. The screen 802 covers the outside of the sieving mechanism 7 and is used to separate fine powder from large solid residues during grinding. The sieving mechanism 7 is driven by the drive motor 302, thereby rotating inside the screen 802 and driving the dry powder mixture to move relative to the screen 802, so that the fine powder can pass through the small sieve holes on the screen 802 and be discharged from the first cavity 202. One end of the filter cylinder 801 is engaged with the connecting ring 201, and the other end extends to one side of the baffle 203 and abuts against the baffle 203. The inner wall of the connecting ring 201 is provided with several engaging parts 2011. The outer ring of the filter cylinder 801 is provided with slots 803 that are engaged with the engaging parts 2011 respectively. The baffle 203 is provided with a positioning ring 2032 that is engaged with the outer ring of the end of the filter cylinder 801 away from the connecting ring 201. The baffle 203 is also provided with a separation port 2031 at the bottom of the inner side of the positioning ring 2032, which connects the first cavity 202 and the second cavity 204. Large particles of residue blocked by the screen 802 are pushed by the screening mechanism 7 through the separation port 2031 into the second cavity 204 and discharged from the second cavity 204, thereby realizing grinding and screening.

[0028] Furthermore, the screening mechanism 7 includes a stirring shaft 701 rotatably connected to the separation mechanism 2, which rotates under the drive of the drive motor 302 to agitate the dry powder mixture and promote its screening. Several cleaning plates 702 are installed on the shaft inside the first cavity 202. The cleaning plates 702 are equidistantly distributed around the stirring shaft 701. The end face of the cleaning plates 702 away from the stirring shaft 701 is densely covered with bristles 703. The end of the bristles 703 away from the cleaning plate 702 is in contact with the screen 802. The stirring shaft 701 drives the cleaning plates 702 to rotate, and the bristles 703 continuously contact the surface of the screen 802 to remove adhering particles and prevent the screen holes from clogging.

[0029] Furthermore, the first cavity 202 has a powder outlet 2022 on one side of its bottom, and a first inclined guide plate 2021 is also provided inside. One end of the first inclined guide plate 2021 is connected to the powder outlet 2022, and the other end extends upward at an incline to connect with the upper end of the side wall of the first cavity 202, which is used to guide the fine powder after being screened by the filter screen to be discharged through the powder outlet 2022. The second cavity 204 has a slag outlet 2042 on one side of its bottom and a second inclined guide plate 2041 inside. One end of the second inclined guide plate 2041 is connected to the slag outlet 2042, and the other end extends upward at an incline to connect with the upper end of the side wall of the second cavity 204, which is used to guide the residue to be discharged through the slag outlet 2042.

[0030] Furthermore, the filter cylinder 801 has a conical cross-sectional shape, and its diameter gradually decreases from one end of the connecting ring 201 to the other end of the positioning ring 2032. This is used to expand the screening area of ​​the filter screen near the feed inlet 401 in the first cavity 202. Several cleaning plates 702 extend spirally along the axial direction of the stirring shaft 701 to push the material to move axially during the filtration and screening process, avoiding local material retention on the screen 802, and ensuring that the material is in full contact with the screen 802 during the movement, thereby improving the screening efficiency and preventing large particles from clogging the screen holes.

[0031] Working principle: First, select the grinding mode or powder grinding mode according to the processing requirements. In the grinding mode, adjust the switching mechanism 6 to connect the discharge port 102 with the outside of the equipment through the guide plate 5. Mix the material to be ground with water in proportion and add it into the feeding mechanism 1 through the feeding hopper. Under the push of the feeding shaft 103, it enters the grinding mechanism 101 for grinding. The solid-liquid mixture produced after grinding can be directly discharged into the container outside the equipment through the guide plate 5. In grinding mode, the switching mechanism 6 is adjusted so that the guide plate 5 connects the discharge port 102 with the feed port 401 of the separation mechanism 2, so that the ground dry mixture enters the first chamber 202 through the guide plate 5. The drive motor 302 drives the stirring shaft 701 to rotate the cleaning plate 702, so that the bristles 703 on the cleaning plate 702 push the dry powder mixture to move on the screen 802, so that the fine powder with a particle size smaller than the mesh of the screen 802 passes through the screen 802 and is discharged from the powder outlet 2022. The residue is pushed into the second chamber 204 and discharged.

[0032] Example 2, as Figure 9 , Figure 10 As shown, the difference between Embodiment 2 and Embodiment 1 is that the filter cylinder 801 is a column, and several cleaning plates 702 extend parallel to the axial direction of the stirring shaft 701, generating a radial stirring effect on the material inside the screen 802. Its axial pushing ability is much weaker than that of the spiral cleaning plate 702 in the first embodiment, which makes the material stay in the screen 802 for a longer time and has more sufficient contact with the screen 802. It is suitable for materials that require finer screening, making the screening more thorough.

[0033] Working principle: During the grinding operation, the drive motor 302 simultaneously drives the feed shaft 103 and the stirring shaft 701 of the screening mechanism 7 to rotate. The dry mixture is guided from the discharge port 102 into the cylindrical filter cylinder 801 through the guide plate 5. The stirring shaft 701 drives the parallel cleaning plate 702 to rotate. The bristles 703 continuously clean the surface of the screen 802 to prevent clogging. The cleaning plate 702 radially agitates the material, causing it to be turned over. This allows fine powder that meets the mesh size to pass through the screen 802 holes and fall into the bottom of the first chamber 202 and finally be discharged from the powder outlet 2022. Large particles that fail to pass through the screen 802 are slowly pushed by the cleaning plate 702 and gradually move towards the separation port 2031 connected to the second chamber 204, and finally enter the second chamber 204 and be discharged from the slag outlet 2042, completing the grinding and screening process.
