Description

Technical Field

[0001] This utility model relates to the field of starch raw material pulverization technology, and in particular to a pulverizing device for purifying amylose. Background Technology

[0002] Amylose purification is the process of separating and obtaining high-purity amylose from starch raw materials (such as corn, potatoes, rice, etc.). In the production of high-purity amylose, a grinding mill is often used in the starch processing industry to crush the starch raw materials. By driving the rotation of the drum inside the grinding mill housing, several saw blades are installed on the surface of the drum. The narrow front end of the raw material comes into contact with the saw blades to shred it. The slurry drawn into shreds is carried by the drum to the lower part of the saw blades, where it is ground between the drum and the screen, causing the cell walls to break and releasing starch granules, which facilitates subsequent purification operations.

[0003] The saw blades on existing drums are generally fixed to the clamping strips by bolts, rivets, or slots. The clamping strips are then bolted into the wedge-shaped grooves on the outer surface of the drum. The saw teeth on the saw blades generally protrude about 3mm above the drum surface. Since the saw blades are usually double-sided, they will experience wear during the long-term crushing of starch raw materials on the drum. It is necessary to periodically switch the saw tooth surfaces on both sides of the saw blades on the drum. Therefore, it is necessary to disassemble the entire clamping strip and saw blade installed in the wedge-shaped grooves on the outer surface of the drum before the saw blades can be flipped over and reassembled into the wedge-shaped grooves on the drum. This installation process is cumbersome and inconvenient, and it is not convenient to quickly switch the saw blade surfaces on the drum. Therefore, this application is made. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a pulverizing device for purifying amylose, thereby solving the aforementioned problems.

[0011] Preferably, the grinding machine drum is provided with a drive shaft, one end of which is rotatably mounted on the inner wall of the grinding chamber of the grinding machine via a bearing, and the other end of which extends outside the grinding machine.

[0012] In this application, when it is necessary to flip the corresponding double-sided saw blade inside the mounting cavity of the grinding machine drum, part of the grinding machine housing is removed, exposing the grinding machine drum on the outside. By holding the middle plate on one side of the positioning plate in sequence, pulling the positioning plate outward and rotating it, the positioning plate that limits the first and second clamping bars is disengaged.

[0016] During the long-term crushing of starch raw materials by the saw blade on the drum, a certain amount of wear will occur. It is necessary to periodically switch the saw tooth surfaces on both sides of the saw blade on the drum. Therefore, it is necessary to disassemble the entire clamping bar and saw blade installed in the wedge groove on the outer surface of the drum before the saw blade can be flipped over and reassembled into the wedge groove on the drum. This installation process is cumbersome and inconvenient, and does not facilitate quick switching of the saw blade surfaces on the drum. To solve the above problems, this embodiment discloses a crushing device for purifying amylose, including: Figure 1 The file grinder drum 100 shown; as Figure 1 The diagram shows several crushing components 200 and several limiting components 300.

[0017] like Figure 1 As shown, the grinding drum 100 is installed inside the grinding chamber of the grinding machine. A drive shaft 110 is installed on the grinding drum 100.

A pulley is installed on the output shaft of the drive motor. The same belt is installed between the two pulleys. The drive motor can drive the grinding drum 100 inside the grinding chamber to rotate, thereby crushing the starch raw material (the specific working process of the grinding machine is a very mature technology and will not be described in detail here).

[0018] like Figure 3 and Figure 5 As shown, in order to install several crushing components 200, the outer surface of the grinding mill drum 100 has several mounting cavities 101. The several mounting cavities 101 on the outer surface of the grinding mill drum 100 are arranged in a circumferential array. The cross-section of the mounting cavity 101 is notched and circular. Several crushing components 200 are respectively arranged in the several mounting cavities 101 on the outer surface of the grinding mill drum 100. The grinding mill drum 100 is configured to crush the starch raw material in the grinding cavity through the several crushing components 200 on the surface of the grinding mill drum 100 when it rotates. The crushing assembly 200 includes: a first clamping bar 210, a second clamping bar 220, and a double-sided saw blade 230; the first clamping bar 210 has several first protrusions 211 on one side, and first side openings 2101 at both ends. Both sides of the first clamping bar 210 are arc-shaped and adapted to the outer surface of the grinding machine drum 100, and one side of the second clamping bar 220 is arc-shaped and adapted to the inner wall of the mounting cavity 101; the second clamping bar 220 has several second protrusions 221 on one side, and second side openings 2201 at both ends. Both sides of the second clamping bar 220 are arc-shaped and adapted to the outer surface of the grinding machine drum 100, and one side of the second clamping bar 220 is arc-shaped and adapted to the inner wall of the mounting cavity 101; the double-sided saw blade 230 has several round holes 2301.

[0019] like Figure 5 As shown, several first protrusions 211 on one side of the first clamping bar 210 are respectively inserted into the corresponding round holes 2301 on the double-sided saw blade 230, and several second protrusions 221 on one side of the second clamping bar 220 are respectively inserted into the corresponding round holes 2301 on the double-sided saw blade 230. After the first clamping bar 210, the second clamping bar 220 and the double-sided saw blade 230 are assembled, they are inserted into the corresponding mounting cavity 101 on the outer surface of the grinding machine drum 100; thus realizing the insertion and installation of the crushing component 200 into the corresponding mounting cavity 101 on the outer surface of the grinding machine drum 100.

[0020] like Figure 3 and Figure 4 As shown, in order to install several limiting components 300, both ends of the grinding mill drum 100 have several circular cavities 1001 and side grooves 1002; several limiting components 300 are respectively arranged in several circular cavities 1001 and side grooves 1002 at both ends of the grinding mill drum 100, and the crushing component 200 in the mounting cavity 101 can be limited and fixed by two corresponding limiting components 300 at both ends of the grinding mill drum 100; The limiting assembly 300 includes: a circular plate 310, a connecting rod 320, a positioning plate 330, and a spring 340; the circular plate 310 is movably installed in the circular cavity 1001; one end of the connecting rod 320 is fixedly installed on one side of the circular plate 310, and the other end extends movably into the side groove 1002; the positioning plate 330 is fixedly installed on one end of the connecting rod 320 and movably inserted into the side groove 1002, and is composed of a circular plate and side ears on both sides thereon. The two side ears on the positioning plate 330 are respectively inserted into the first side opening 2101 of the corresponding first clamping bar 210 and the second side opening 2201 of the corresponding second clamping bar 220, thereby achieving the limiting of the space within the mounting cavity 101. The first clamping bar 210 and the second clamping bar 220 are used for position limiting and fixing. One side of the positioning plate 330 has a groove 3301, and an intermediate plate 331 is disposed within the groove 3301. One end of the spring 340 abuts against one side of the circular plate 310, and the other end abuts against the inner wall of one side of the circular cavity 1001, facilitating the rotation of the circular plate 310 within the cavity 1001. This allows the installer to hold the positioning plate 330 on the intermediate plate 331 on one side and pull it outwards, causing the connecting rod 320 to drive the circular plate 310 to slide outwards within the cavity 1001. At this time, the spring 340 is compressed and deformed, causing the positioning plate 330 to rotate. Figure 4 As shown.

[0021] In this application, when it is necessary to flip the corresponding double-sided saw blade 230 in the mounting cavity 101 of the grinding machine drum 100, part of the grinding machine housing is removed, exposing the grinding machine drum 100 on the outside. By holding the middle plate 331 on one side of the positioning plate 330 in sequence, the positioning plate 330 is pulled outward and rotated, so that the positioning plate 330 that limits the first clamping bar 210 and the second clamping bar 220 is disengaged. Then, it is convenient to rotate the assembled crushing component 200 in the mounting cavity 101 of the grinding machine drum 100 by 180 degrees to achieve the flipping adjustment of the double-sided saw blade 230. In this application, it is not necessary to disassemble the crushing component 200 in the mounting cavity 101 for flipping adjustment. The double-sided saw blade 230 can be flipped simply by turning the crushing component 200 in the mounting cavity 101. The operation is simple and fast, and it is convenient to quickly flip the double-sided saw blade 230.
