Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of centrifuge feeding devices, and more specifically, to a low-shear feeding device for a high-speed centrifuge. Background Technology
[0002] In the production and processing of isoborneol, an automatic centrifuge is generally required. Existing centrifuges consist of a casing and a centrifugal drum, with the drum located inside the casing. During operation, the material (isoborneol hydrolysate) is injected into the drum through a feed pipe mounted on a cover plate at the top of the casing, and the centrifuge is then ready for use. However, the current feeding method, where the feed pipe is directly inserted into the centrifugal drum and the material is sprayed directly from the end of the pipe, leads to uneven material distribution, thus causing problems that affect production and processing.
[0003] According to Chinese Patent CN202420344755.2, a low-shear feeding device for a high-speed centrifuge is disclosed. This application uses a feeding pipe that is closed at the bottom and open at the top, with the top of the feeding pipe fixedly installed to a cover plate at the top of the centrifuge's outer casing. The bottom end of the feeding pipe is inserted into the centrifuge drum, and the feeding pipe has several material distribution holes evenly arranged vertically. This effectively reduces the shear force between the material and the inner wall of the centrifuge drum during the feeding process, thereby preventing the material from being broken by shear force. In existing low-shear feeding devices for high-speed centrifuges, the feeding pipe impacts the guide block when spraying material particles at high speed, and continuous high-intensity impact can cause damage to the guide block.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A feed pipe is located at the top of the cover. The bottom end of the feed pipe passes through the cover and extends into the centrifuge drum. Several evenly distributed arc-shaped mounting blocks are located in the centrifuge drum and on the outer wall of the feed pipe. The arc-shaped mounting blocks are connected to the feed pipe via clamping components. A guide plate is located on one side of each arc-shaped mounting block and is connected to the arc-shaped mounting block via a buffer mechanism. Several evenly distributed material distribution holes are opened in the centrifuge drum and on the outer wall of the feed pipe. The top end of the feed pipe is connected to a conveying pipe.
[0008] Preferably, the clamping assembly includes symmetrically arranged arc-shaped clamping plates on one side of the arc-shaped mounting block, and the two sets of arc-shaped clamping plates are connected by bolts on the side away from the arc-shaped mounting block. A positioning groove is provided on the concave surface of the arc-shaped mounting block, and a positioning post matching the positioning groove is provided on the outer wall of the feed pipe.
[0009] Preferably, both sets of the arc-shaped clamps are hinged to the arc-shaped mounting block.
[0010] Preferably, the buffer mechanism includes a fixed post on one side of the arc-shaped mounting block, a buffer groove at the bottom of the fixed post, a matching slider in the buffer groove, guide rods symmetrically arranged and penetrating the slider in the buffer groove, a buffer spring sleeved on one side of the slider and on the outer wall of the guide rod, the bottom of the slider being connected to the guide plate via a pressure rod, and the guide plate being hinged to the arc-shaped mounting block.
[0011] Preferably, the slider has a sliding hole that matches the guide rod, the slider is connected to the fixed post through a buffer spring, and the slider is provided with a damper connected to the fixed post at the location of the buffer spring.
[0012] Preferably, the two ends of the pressure rod are hinged to the guide plate and the slider, respectively.
[0013] The beneficial effects of this utility model are as follows: by setting a buffer mechanism, when material particles impact the guide plate, the guide plate has a buffering and shock absorption effect, preventing the guide plate from being damaged due to long-term impact and affecting its service life. At the same time, the buffer of the guide plate also prevents the material particles from being crushed when impacting the guide plate.

The clamping assembly includes symmetrically arranged arc-shaped clamping plates 9 on one side of the arc-shaped mounting blocks 5, the two sets of arc-shaped clamping plates 9 being connected by bolts 19 on the side away from the arc-shaped mounting blocks 5, a positioning groove 10 on the concave surface of the arc-shaped mounting blocks 5, and a positioning post 11 matching the positioning groove 10 on the outer wall of the feed pipe 4.

When installing the guide plate 6 and the feed pipe 4, first insert the positioning post 11 on the outer wall of the feed pipe 4 into the positioning groove 10 on the concave surface of the arc-shaped mounting block 5, then rotate the two sets of arc-shaped clamping plates 9 to clamp the feed pipe 4, and tighten the bolts 19 to fix the two sets of arc-shaped clamping plates 9. At this time, the guide plate 6 is installed. The clamping assembly facilitates the disassembly and assembly of the guide plate and the feed pipe, making it more flexible and convenient to use.
[0029] Example 3;
[0030] like Figure 1-6As shown, the device includes a housing 1, a housing cover 2 at the top of the housing 1, a centrifugal drum 3 inside the housing 1, a feed pipe 4 at the top of the housing cover 2, the bottom end of the feed pipe 4 passing through the housing cover 2 and extending into the centrifugal drum 3, a number of evenly distributed arc-shaped mounting blocks 5 in the centrifugal drum 3 and on the outer wall of the feed pipe 4, the arc-shaped mounting blocks 5 being connected to the feed pipe 4 via a clamping assembly, a guide plate 6 on one side of the arc-shaped mounting blocks 5, the guide plate 6 being connected to the arc-shaped mounting blocks 5 via a buffer mechanism, a number of evenly distributed material distribution holes 7 in the centrifugal drum 3 and on the outer wall of the feed pipe 4, and the top end of the feed pipe 4 being connected to a conveying pipe 8. The buffer mechanism includes a fixed post 12 on one side of the arc-shaped mounting block 5. A buffer groove 13 is formed at the bottom of the fixed post 12, and a matching slider 14 is provided in the buffer groove 13. Guide rods 15, symmetrically arranged and penetrating the slider 14, are provided in the buffer groove 13. A buffer spring 16 is fitted on one side of the slider 14 and on the outer wall of the guide rod 15. The bottom end of the slider 14 is connected to a guide plate 6 via a pressure rod 17.

When material particles are conveyed to the feed pipe 4 through the conveying pipe 8, they are then sprayed onto the guide plate 6 through the material distribution holes 7 on the outer wall of the feed pipe 4. When the guide plate 6 is impacted by the material particles, the guide plate 6 presses the slider 14 through the pressure rod 17.

Then, rotate the two sets of arc-shaped clamping plates 9 to clamp the feed pipe 4, and tighten the bolts 19 to fix the two sets of arc-shaped clamping plates 9. At this time, the guide plate 6 is installed. The clamping assembly facilitates the disassembly and assembly of the guide plate and the feed pipe, making it more flexible and convenient to use. When the material particles are conveyed into the feed pipe 4 through the conveying pipe 8, the material particles are then sprayed onto the guide plate 6 through the material distribution hole 7 on the outer wall of the feed pipe 4. When the guide plate 6 is impacted by material particles, the guide plate 6 presses the slider 14 through the pressure rod 17. The slider 14, under pressure, begins to slide on the guide rod 15, compressing the buffer spring 16 to achieve a buffering effect. At the same time, the slider 14 also compresses the damper 18, so that the guide plate 6 has a buffering and shock-absorbing effect. By setting up a buffering mechanism, when material particles impact the guide plate, the guide plate has a buffering and shock-absorbing effect, preventing the guide plate from being damaged due to long-term impact and affecting its service life. At the same time, the buffering of the guide plate also prevents the material particles from being crushed when impacting the guide plate.
[0032] In summary, by means of the above-mentioned technical solution of this utility model, when the material particles impact the guide plate, the guide plate has a buffering and shock-absorbing effect, preventing the guide plate from being damaged due to long-term impact and affecting its service life. At the same time, the buffering of the guide plate also prevents the material particles from being crushed when impacting the guide plate.
