Description

Technical Field

[0001] The utility model belongs to the technical field of grain drying, in particular to a dust removal device for a grain drying tower. Background Art

[0002] During the grain drying process, a large amount of fine dust will be generated due to impurities such as dust, sand, husks and broken grains attached to the surface of the grain, as well as the friction and impact between grain particles during the drying process. This dust will not only affect the working environment inside the drying tower, but may also cause wear and tear on the production equipment and reduce the service life of the equipment. At the same time, the flying dust will also pose a threat to the health of production personnel, and may even cause safety accidents such as explosions in some cases.

[0003] During the reuse of the existing device, grains are usually piled up in the drying tower with a high stacking density. This tight stacking makes the internal space small, and it is difficult for the airflow and dust removal equipment to fully penetrate between each layer of grain particles, especially between the deep grain particles, resulting in dust in the gaps being difficult to be carried away by the airflow or captured by the dust removal equipment; during the drying process, the airflow distribution may be uneven, resulting in faster airflow speeds in some areas and insufficient airflow in other areas. This uneven airflow distribution makes it easy for dust on the surface of some grain particles to be blown away, while dust hidden inside or in the gaps is difficult to be impacted by sufficient airflow and thus difficult to be removed. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] like Figures 1 to 8 As shown, the utility model provides a dust removal device for a grain drying tower, comprising a support frame 1, a dust removal bin 2 is fixedly mounted on the inner wall of the support frame 1, a grain storage box 3 is arranged inside the dust removal bin 2, a switch door plate is designed at the top of the grain storage box 3, a drying pipe interface 18 is fixedly mounted on the top outer wall of the dust removal bin 2, a dust outlet pipe 19 is fixedly mounted at the bottom of the dust removal bin 2, a fan 20 is fixedly mounted at the bottom of the dust outlet pipe 19, a cover plate 21 is fixedly mounted on the top of the dust removal bin 2, and a vibration mechanism is arranged inside the dust removal bin 2;

[0026] There are three groups of vibration mechanisms, including a motor 7 and a rotating rod 8 rotatably installed inside the dust removal bin 2. The ends of the motor 7 and the rotating rod 8 that are away from each other extend out of the dust removal bin 2. A connecting rod 11 is hingedly installed on the side where the rotating rod 1 8 and the rotating rod 2 9 are close to each other. A connecting rod 12 is hingedly installed on the top of the connecting rod 11. A movable cavity 13 is opened on the top of the connecting rod 2 12. A vibration column 14 is fixedly installed on the bottom of the grain box 3, and the vibration column 14 is slidably connected to the movable cavity 13.

[0027] A connecting rod mechanism is formed by connecting rod one 11 and connecting rod two 12 between rotating rod one 8 and rotating rod two 9. When rotating rod one 8 rotates, connecting rod one 11 drives connecting rod two 12 and rotating rod two 9 to perform reciprocating or circular motion. An active cavity 13 is provided at the top of connecting rod two 12, and a vibration column 14 is fixedly installed at the bottom of the grain box 3. The vibration column is slidably connected to the active cavity 13. With the movement of connecting rod two 12, the active cavity 13 generates an up and down or left and right thrust on the vibration column 14, thereby vibrating the grain box 3 and the grain particles therein. The vibration helps to break the static accumulation between the grain particles, promotes the flow and turning of the grain in the grain box 3, and allows the airflow and heat to penetrate the grain layer more evenly, thereby improving the drying and dust removal efficiency.

[0028] like Figures 1 to 8 As shown, a shaking mechanism is provided on the inner wall of the dust removal bin 2, and the shaking mechanism includes a sliding groove 5 opened on the inner wall of the dust removal bin 2, and a rectangular block 4 is fixedly installed on the outer wall of the grain box 3, and the bottom of the rectangular block 4 is elastically connected to the side close to the sliding groove 5 through a spring telescopic rod assembly 6.

[0029] The inner wall of the dust removal bin 2 is connected to the external rectangular block 4 through the spring telescopic rod assembly 6 in the shaking mechanism, so that the grain box 3 can be shaken under the drive of the power source, which helps to break the static accumulation between grain particles and allows the airflow and vibration to penetrate the grain layer more evenly, thereby improving the dust removal effect and reducing dead corners and residues.

[0030] like Figures 1 to 8 As shown, a motor 7 is fixedly mounted on the outer wall of the support frame 1, and the output shaft of the motor 7 is fixedly connected to one end of a rotating rod 8 in the middle.

[0031] The motor 7 is used as the main power source of the dust removal device, and its output shaft directly drives the middle rotating rod 8 to rotate, which reduces the energy loss in the power transmission process, improves the energy utilization efficiency, and ensures that the dust removal device can operate efficiently and stably.

[0032] like Figures 1 to 8 As shown, belts 17 are respectively wound around the outer walls of two adjacent rotating rods 9, and the number of belts 17 is two.

[0033] Through the winding design of the two belts 17, the power between the rotating rods 9 can be transmitted more effectively, ensuring the synchronous operation between the two adjacent rotating rods 9, thereby improving the working efficiency of the entire dust removal device.

[0034] like Figures 1 to 8 As shown, a conical block 141 is fixedly installed at the bottom of the vibration column 14 , and the conical block 141 is elastically connected to the side of the movable cavity 13 that is close to each other through a spring 15 .

[0035] Through the elastic connection of the spring 15, the conical block 141 can more fully contact and collide with the grain particles in the active cavity 13 during the vibration process, which helps to separate the dust and impurities in the grain more thoroughly and improve the dust removal efficiency.

[0036] like Figures 1 to 8 As shown, a second conical block 16 is fixedly installed inside the active cavity 13 , and the second conical block 16 and the first conical block 141 are symmetrically distributed.

[0037] Through the symmetrical distribution design of the conical block 1 141 and the conical block 2 16, the collision between the conical blocks will further amplify the vibration effect, so that the grain particles in the grain box 3 are subjected to stronger vibration.

[0038] like Figures 1 to 8 As shown, there are four groups of shaking mechanisms, and the four groups of shaking mechanisms are designed to be distributed in a circular array with the center of the dust removal bin 2 as the axis.

[0039] By using four sets of shaking mechanisms evenly distributed around the dust removal bin, the dust and impurities carried by the grain in the grain box 3 can be vibrated and separated in all directions and at multiple angles, thereby improving the dust removal efficiency and effect and effectively reducing the impurity residues after the grain is dried.

[0040] The working principle and use process of this utility model:

[0041] The staff first opens the cover 21, puts the grain into the grain box 3, and ensures that the switch door plate is closed and sealed, then closes the cover 21, and then connects the drying pipe interface 18 to the dryer. The drying gas enters the dust removal bin 2 through the drying pipe interface 18 and penetrates the grain layer in the grain box 3, and then starts the motor 7. The motor 7 drives the rotating rod 8 to rotate, and drives the vibration column 14 to vibrate through the connecting rod mechanism (connecting rod 1 11 and connecting rod 2 12). The vibration column 14 drives the grain box 3 to vibrate together, so that the grain particles flow and turn over in the grain box 3, so that the drying gas can penetrate the grain layer more evenly, thereby improving the drying efficiency. While vibrating, the dust and impurities hidden in the grain are exposed. With the drive of the motor 7, the grain box 3 shakes under the action of the shaking mechanism, further promoting the flow and turning of the grain particles. Then the fan 20 is started, and the airflow carries the dust and impurities through the grain layer and enters the bottom of the dust removal bin 2. Finally, it is sucked out by the fan 20 through the dust outlet pipe 19 and discharged to the outside of the dust removal device.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
