Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for dryers, in particular to a dust removal device for vacuum dryers. Background Art

[0002] Vacuum dryer is a kind of equipment that uses vacuum environment to dry materials. It is widely used in chemical, pharmaceutical, food and other industries. The following is a detailed introduction to vacuum dryer and the design and advantages of its dust removal device.

[0003] The vacuum dryer achieves the purpose of drying by reducing the pressure in the drying chamber, lowering the boiling point of water, and evaporating the water of the material at a low temperature. This equipment is particularly suitable for drying heat-sensitive materials because it can effectively remove moisture at a lower temperature without damaging the properties of the material. However, during the drying process, some material dust will be generated and left in the dryer, which needs to be treated by a dust removal device.

[0004] Traditional dust removal devices usually use fans to suck in the dust generated during the drying process and transport it to the collection box to complete the dust treatment. Although this method can handle some dust, it cannot effectively clean the dust attached to the inner wall of the dryer barrel. These residual dusts accumulate over time, which will reduce the working efficiency of the equipment and affect its normal operation. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a dust removal device for a vacuum dryer, aiming to improve the problem that although this method in the prior art can handle some dust, it cannot effectively clean the dust attached to the inner wall of the dryer barrel.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 4 and Figure 5 , the utility model provides an embodiment: a dust removal device for a vacuum dryer, including a bracket 1, a cylinder 2 is fixedly connected to the middle of the bracket 1, a motor 4 is arranged on the upper part of the cylinder 2, a rotating rod 5 is fixedly connected to the output end of the motor 4, a turntable 6 is fixedly connected to the bottom of the rotating rod 5, both sides of the turntable 6 are fixedly connected to the outside of the connecting plate 23, a fixed block 7 is fixedly connected to the outside of the connecting plate 23, both sides of the inside of the fixed block 7 are provided with a first spring 8, a cleaning brush 9 is slidably connected to the inside of the fixed block 7, a collecting box 10 is fixedly connected to the bottom of the bracket 1, a mounting shell 11 is fixedly connected to the outside of the collecting box 10, fans 12 are installed on both sides of the inside of the mounting shell 11, and the collecting box A filter plate 13 is inserted into the interior of 10, and a disassembly assembly 20 is arranged on the outside of the collecting box 10, and the disassembly assembly 20 is used to replace the filter plate 13. One end of a conveying pipe 15 is fixedly connected to the inside of the collecting box 10, and the other end of the conveying pipe 15 passes through the interior of the cylinder 2 and is fixedly connected to a dust collecting port 16. A mounting frame 3 is fixedly connected to the upper part of the cylinder 2, and a motor 4 is fixedly connected to the inside of the mounting frame 3. A feed port 18 is fixedly connected to the left side of the outside of the cylinder 2, and a discharge port 19 is fixedly connected to the lower part of the cylinder 2. A drawer 14 is slidably connected to the inside of the collecting box 10, and fixed rods 17 are fixedly connected to both sides of the outside of the dust collecting port 16, and two fixed rods 17 are fixedly connected to both sides of the inside of the cylinder 2.

[0028] When the dust inside the dryer is processed, the motor 4 fixed in the middle of the mounting frame 3 is started, and the motor 4 starts to drive the rotating rod 5 fixed at its output end to rotate. The rotation of the rotating rod 5 is transmitted to the turntable 6 fixed at the bottom of its outer side, and the turntable 6 rotates with the rotation of the rotating rod 5. The rotation of the turntable 6 further drives the connecting plates 23 fixed on both sides of its outer side to rotate, and the rotation of the connecting plates 23 drives the fixed block 7 fixed on the outside to rotate. The rotation of the fixed block 7 simultaneously drives the first spring 8 set on both sides of its inner side to move, and drives the cleaning brush 9 set inside to rotate. The setting of the first spring 8 ensures that the cleaning brush can always move in contact with the inner wall of the cylinder 2, thereby effectively cleaning the dust attached to the inner wall of the cylinder 2. While the cleaning brush 9 moves and cleans the dust on the inner wall of the cylinder 2, the fan 12 is started, and the dust is sucked in through the dust collecting port 16, and then transported to the inside of the collection box 10 through the conveying pipe 15. The collection box 10 is equipped with a filter plate 13 inside, which can effectively filter the collected dust, prevent dust from entering the fan 12, and ensure the normal operation of the fan 12. When the inside of the collection box 10 is full of dust, the operator only needs to pull out the drawer 14 from the inside of the collection box 10 to clean and maintain the inside of the collection box 10. By arranging the filter plate 13 inside the collection box 10, not only can the dust be effectively filtered, but also the service life and operating efficiency of the fan 12 can be extended, and the dust attached to the inner wall of the dryer cylinder 2 can be easily cleaned. Different from the traditional cleaning method, this method can effectively clean the dust attached to the inner wall of the cylinder 2 and improve the working efficiency of the equipment.

[0029] Reference Figure 2 , Figure 3 and Figure 6 The disassembly and assembly component 20 includes a mounting block 2001, which is fixedly connected to the outside of the collecting box 10, a slider 2002 is slidably connected inside the mounting block 2001, an insertion rod 2005 is fixedly connected to the front side of the outside of the slider 2002, a moving rod 2003 is fixedly connected to the rear side of the outside of the slider 2002, a second spring 2004 is sleeved on the outside of the moving rod 2003, a plug hole 22 is opened inside the filter plate 13, the plug rod 2005 is plugged into the plug hole 22, a through hole 21 is opened inside the mounting block 2001, and the plug rod 2005 is slidably connected inside the through hole 21.

[0030] When the filter plate 13 needs to be disassembled for maintenance, the movable rod 2003 is pulled, and the movable rod 2003 moves to drive the externally fixed slider 2002 to move laterally inside the mounting block 2001. When the slider 2002 moves, the plug rod 2005 fixed on the front side moves synchronously. At this time, the slider 2002 drives the insertion rod 2005 to move, while squeezing the second spring 2004 sleeved on the outside of the moving rod 2003, so that the second spring 2004 is deformed and compressed. When the insertion rod 2005 is completely out of the socket 22, the filter plate 13 can be pulled out from the inside of the collection box 10 for maintenance. After the maintenance of the filter plate 13 is completed, it is reinserted into the collection box 10. The operator releases the moving rod 2003, and the reaction force of the second spring 2004 when released pushes the insertion rod 2005 back into the inside of the socket 22, ensuring that the filter plate 13 is firmly installed, making it easy to disassemble and maintain the filter plate 13. Timely cleaning and maintenance of the filter plate 13 help to extend its service life and reduce the cost caused by frequent replacement.

[0031] Working principle: When the dust inside the dryer is processed, the motor 4 fixed in the middle of the mounting frame 3 is started, and the motor 4 starts to rotate the rotating rod 5 fixed at the output end, and the rotating rod 5 rotates to rotate the rotating disk 6 fixed at the bottom of the outside, and the rotating disk 6 rotates to rotate the connecting plates 23 fixed on both sides of the outside, and the connecting plates 23 rotate to rotate the fixed blocks 7 fixed on the outside, and the fixed blocks 7 rotate to move the first springs 8 set on both sides of the inside and rotate the cleaning brush 9 set inside, and the first spring 8 is set to make the cleaning brush 9 always stick to the inside of the cylinder 2. The wall moves, and the dust attached to the inner wall of the cylinder 2 is cleaned by moving the cleaning brush 9. While cleaning, the fan 12 is started to suck the dust through the dust collecting port 16, and then it is transported to the inside of the collection box 10 through the conveying pipe 15. When the inside of the collection box 10 is full, the drawer 14 is pulled out from the inside of the collection box 10 to clean the inside of the collection box 10. By arranging a filter plate 13 inside the collection box 10, the collected dust can be filtered to avoid the suction of the fan 12, so that the dust attached to the inner wall of the dryer cylinder 2 is conveniently removed. The cleaning is different from the traditional cleaning method. This method can effectively clean the dust attached to the inner wall of the cylinder 2, thereby improving the working efficiency of the equipment. Then, when the filter plate 13 needs to be disassembled for maintenance, the moving rod 2003 is pulled, and the moving rod 2003 moves with the slider 2002 fixed externally to move laterally inside the mounting block 2001. When the slider 2002 moves, the plugging rod 2005 fixed externally to the front side moves with it. When the slider 2002 moves with the plugging rod 2005, the second spring 2004 sleeved on the outside of the moving rod 2003 is pressed. The second spring 2004 is squeezed and deformed, and then, when the insertion rod 2005 is disengaged from the insertion hole 22, the filter plate 13 can be pulled out from the interior of the collection box 10 for maintenance. During installation, it is only necessary to insert the filter plate 13 into the collection box 10, and then loosen the moving rod 2003, and insert the insertion rod 2005 into the interior of the insertion hole 22 under the reaction force of the second spring 2004, so that the filter plate 13 can be easily disassembled and maintained. Timely cleaning and maintenance of the filter plate 13 helps to extend its service life and reduce the cost caused by frequent replacement.
