Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a clog-proof feed dryer. Background Technology

[0002] Feed dryers are widely used in building materials, metallurgy, chemical, and cement industries for drying materials such as slag, limestone, coal powder, clay, etc. Rotary dryers are highly adaptable to various materials and are simple and reliable to operate.

[0003] Existing feed dryers have a stirring structure inside the feed hopper to prevent clogging. However, adding this structure itself can easily cause clogging during feeding, and the unblocking effect needs to be improved.

[0004] To address the above problems, this utility model provides a feed dryer that can prevent clogging. Utility Model Content

[0005] The purpose of this invention is to provide a feed dryer that can prevent clogging. By rotating the spiral blades and advancing them in a straight line, the feed that is blocked in the feed hopper can be effectively cleared. After clearing, the spiral blades return to their original position and leave the upper end of the feed hopper, so that the feed can be put into the feed hopper without obstruction, thereby solving the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feed dryer that can prevent clogging, comprising a dryer body and a feed hopper fixed at the feed end, a support plate fixed at the upper edge of the feed hopper, a rectangular frame and a first motor respectively provided at the upper and lower ends of the support plate, a lifting plate provided inside the rectangular frame, a lead screw provided inside the lifting plate, a second motor provided at the upper end of the lead screw, a connecting plate fixed at the end of the lifting plate, a third motor and a rotating rod respectively provided at the upper and lower ends of the connecting plate, and a spiral blade fixed on the outer side of the rotating rod.

[0007] Furthermore, a rotating seat is fixed at the bottom of the rectangular frame, and the outer side of the rotating seat is rotatably connected to the inner side of the middle of the support plate via a bearing. A U-shaped plate is fixed at the bottom of the support plate, and the first motor is fixedly installed at the middle of the bottom of the U-shaped plate, with its output end extending upward and fixedly connected to the middle of the bottom of the rotating seat.

[0008] Furthermore, the lead screw and the lifting plate are internally threaded at the end away from the connecting plate, the outer side of the lifting plate is slidably connected to the inner side of the rectangular frame, the second motor is fixedly installed at the upper end of the rectangular frame and its output end extends downward and is fixedly connected to the upper end of the lead screw, and the outer side of the bottom end of the lead screw is rotatably connected to the inner bottom end of the rectangular frame through a bearing.

[0009] Furthermore, the third motor is fixedly mounted on the upper middle part of the connecting plate, and the output end of the third motor extends downward and is fixedly connected to the upper end of the rotating rod.

[0010] Furthermore, the spiral blades do not interfere with the feed hopper during their movement, and the depth of the spiral blades' advance matches the depth inside the feed hopper.

[0011] Furthermore, the central axis of the helical blades coincides with the central axis of the feed hopper during propulsion.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides an anti-clogging feed dryer. The feed to be dried is fed into the feed hopper. If a blockage occurs, a first motor drives a rectangular frame to rotate horizontally at a certain angle, causing the spiral blades on the lifting plate to rotate synchronously to the center of the feed hopper. Then, a third motor drives a rotating rod to rotate, causing the spiral blades to rotate synchronously. Simultaneously, a second motor starts and drives a lead screw to rotate, causing the lifting plate to move vertically downwards, which in turn causes the rotating spiral blades to move vertically downwards synchronously, clearing the blockage in the feed hopper. The spiral blades not only compress the feed downwards but also push it downwards during rotation, ensuring effective clearing. After clearing, the spiral blades stop rotating and return to their vertically upward position. Finally, the first motor drives the spiral blades to rotate horizontally away from the top of the feed hopper, allowing the feed to be fed into the hopper without obstruction. The purpose of this design is to effectively clear the blockage in the feed hopper by rotating and linearly pushing the spiral blades, and then allowing the spiral blades to return to their original position after clearing, ensuring unobstructed feeding.

[0020] To solve the technical problem of how to effectively prevent clogging, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0021] A clog-resistant feed dryer includes a dryer body 1 and a feed hopper 2 fixed at the feed end. A support plate 3 is fixed at the upper edge of the feed hopper 2. A rectangular frame 7 and a first motor 5 are respectively provided at the upper and lower ends of the support plate 3. A lifting plate 10 is provided inside the rectangular frame 7. A lead screw 8 is provided inside the lifting plate 10. A second motor 9 is provided at the upper end of the lead screw 8. A connecting plate 11 is fixed at the end of the lifting plate 10. A third motor 12 and a rotating rod 13 are respectively provided at the upper and lower ends of the connecting plate 11. A spiral blade 14 is fixed on the outer side of the rotating rod 13.

[0022] Specifically, the feed to be dried is placed into the feeding hopper 2. If a blockage occurs, the first motor 5 drives the rectangular frame 7 to rotate horizontally at a certain angle, causing the spiral blades 14 on the lifting plate 10 to rotate synchronously to the center position of the feeding hopper 2. Then, the third motor 12 drives the rotating rod 13 to rotate, causing the spiral blades 14 to rotate synchronously. At the same time, the second motor 9 starts and drives the lead screw 8 to rotate, causing the lifting plate 10 to move vertically downward, thereby causing the rotating spiral blades 14 to move vertically downward synchronously, clearing the blockage of feed in the feeding hopper 2. In addition to squeezing the feed downward, the spiral blades 14 can also push the feed downward when rotating, ensuring effective clearing. After clearing, the spiral blades 14 stop rotating and return to their vertical position. Finally, the first motor 5 drives the spiral blades 14 to rotate horizontally away from the upper end of the feeding hopper 2, so that the feed can be put into the feeding hopper 2 without obstruction. The purpose of this design is to effectively clear the feed blocked in the feed hopper 2 by rotating the spiral blade 14 and advancing it in a straight line. After clearing, the spiral blade 14 returns to its original position and leaves the upper end of the feed hopper 2, so that the feed can be put into the feed hopper 2 without obstruction.

[0023] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0024] A rotating seat 4 is fixedly installed at the bottom of the rectangular frame 7. The outer side of the rotating seat 4 is rotatably connected to the inner side of the middle of the support plate 3 via a bearing. A U-shaped plate 6 is fixedly installed at the bottom of the support plate 3. The first motor 5 is fixedly installed at the middle of the bottom of the U-shaped plate 6, and its output end extends upward and is fixedly connected to the middle of the bottom of the rotating seat 4. The purpose of this design is to drive the rotating seat 4 to rotate, thereby causing the rectangular frame 7 to rotate synchronously in the horizontal direction. The design of the rotating seat 4 facilitates the stable driving of the rectangular frame 7 by the first motor 5.

[0025] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0026] The lead screw 8 is internally threaded to the end of the lifting plate 10 away from the connecting plate 11. The outer side of the lifting plate 10 is slidably connected to the inner side of the rectangular frame 7. The second motor 9 is fixedly installed on the upper end of the rectangular frame 7 and its output end extends downward and is fixedly connected to the upper end of the lead screw 8. The outer side of the bottom end of the lead screw 8 is rotatably connected to the inner bottom end of the rectangular frame 7 through a bearing. The purpose of this design is that the second motor 9 drives the lead screw 8 to rotate, thereby driving the lifting plate 10 to rise and fall vertically, and in turn driving the connecting plate 11 to rise and fall vertically synchronously.

[0027] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0028] The third motor 12 is fixedly installed in the middle of the upper end of the connecting plate 11. The output end of the third motor 12 extends downward and is fixedly connected to the upper end of the rotating rod 13. The purpose of this design is to drive the spiral blades 14 on the outside of the rotating rod 13 to rotate, thereby squeezing the feed and propel it in a spiral.

[0029] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0030] The spiral blade 14 does not interfere with the feed hopper 2 during its movement, and the propulsion depth of the spiral blade 14 matches the internal depth of the feed hopper 2. The purpose of this design is to ensure the rationality of the structure.

[0031] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0032] When the spiral blade 14 is pushed forward, its central axis coincides with the central line of the feed hopper 2. This design aims to ensure the dredging effect.

[0033] In summary: When the feed to be dried is placed into the feeding funnel 2, if a blockage occurs, the first motor 5 drives the rectangular frame 7 to rotate horizontally at a certain angle, causing the spiral blades 14 on the lifting plate 10 to rotate synchronously to the center position of the feeding funnel 2. Then, the third motor 12 drives the rotating rod 13 to rotate, causing the spiral blades 14 to rotate synchronously. At the same time, the second motor 9 starts and drives the lead screw 8 to rotate, causing the lifting plate 10 to move vertically downward, thereby causing the rotating spiral blades 14 to move vertically downward synchronously, clearing the blockage of feed in the feeding funnel 2. In addition to squeezing the feed downward, the spiral blades 14 can also push the feed downward while rotating, ensuring effective clearing. After clearing, the spiral blades 14 stop rotating and return to their vertical position. Finally, the first motor 5 drives the spiral blades 14 to rotate horizontally away from the upper end of the feeding funnel 2, so that the feed can be put into the feeding funnel 2 without obstruction. The purpose of this design is to effectively clear the feed blocked in the feed hopper 2 by rotating the spiral blade 14 and advancing it in a straight line. After clearing, the spiral blade 14 returns to its original position and leaves the upper end of the feed hopper 2, so that the feed can be put into the feed hopper 2 without obstruction.
