Description

Technical Field

[0001] The utility model relates to the technical field of drying ovens, and more specifically to a layered electric heating blast drying oven. Background Art

[0002] The electric heating blast drying oven can quickly evaporate the moisture on the surface of the object to achieve the purpose of drying. In laboratory research, some materials need to be tested or prepared in a dry state to ensure their performance and quality. In addition, for some moisture-sensitive materials, keeping them dry can extend their service life. In order to increase the efficiency of use, a layered drying oven is usually selected for testing.

[0003] Although the layered drying oven can test more items, in the existing device, the drying oven usually blows air to dry the items first, and at the same time, heats the inside of the box to increase the temperature, thereby achieving the effect of drying the items. However, the storage rack and drying port of the device are usually fixed, which causes the items adjacent to the drying port to be dried and heated for a long time, resulting in over-drying, and the items on the upper layer block the hot air, so that the wind force received by the bottom layer becomes smaller, resulting in poor drying effect, which may eventually cause uneven drying of the items to be tested, thereby reducing the drying quality and affecting the final test results. When drying larger items, the drying port can only dry one end of the item, while the rest of the area is dried at high temperature, which will increase the time required for drying, waste the wind force generated by drying, and reduce the drying efficiency. Therefore, it needs to be improved and optimized. Utility Model Content

[0033] 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.

[0034] like Figures 1 to 8 As shown, the utility model provides a layered electric heating blast drying oven, comprising a drying oven 1, a storage box 2 is movably installed inside the drying oven 1, and a fan housing 3 is fixedly installed on the top of the drying oven 1;

[0035] A drying mechanism is fixedly installed inside the fan housing 3;

[0036] The swing mechanism is fixedly installed inside the drying box 1, and one end of the swing mechanism is movably connected to the drying mechanism;

[0037] A horizontal rotating mechanism, one end of which is rotatably mounted on the inner wall of the storage box 2, and the other end of which is fixedly mounted on the bottom of the storage box 2;

[0038] The power mechanism is fixedly mounted on the front of the storage box 2 and is fixedly connected to the horizontal rotation mechanism;

[0039] Among them, the swing mechanism includes a gear 2 8 rotatably installed on the left side of the drying mechanism, and the gear 2 8 and the drying mechanism are connected by a transmission belt 1 9. The swing mechanism also includes a gear 3 10 fixedly installed inside the drying box 1, and the gear 3 10 and the gear 2 8 are connected by a transmission belt 2 11. A rotating rod 12 is rotatably installed on the left side of the gear 3 10, and the rotating rod 12 and the connecting rod 13 are hinged to each other, and the connecting rod 13 is rotatably connected to the drying mechanism.

[0040] When the items need to be dried, the staff will pull out the storage box 2 inside the drying box 1, and then lay the items to be dried flat on the storage plate 25, and then reset the storage box 2, and then start the motor 14. The operation of the motor 14 drives the heating fan 6 to rotate, so that the heating fan 6 heats the external wind and blows it into the drying port 7. At the same time, the operation of the motor 14 drives the gear 15 to rotate, and the gear 15 drives the gear 2 8 to rotate through the transmission belt 19. The gear 28 drives the gear 3 10 to rotate through the transmission belt 2 11. The rotation of the gear 3 10 rotates the rotating rod 12. When the rotating rod 12 rotates, it pulls the connecting rod 13 to the left or right, so that the connecting rod 13 drives the drying port shell 14 to start swinging left and right, so as to perform all-round hot air drying on the items to be detected in the storage box 2. When the items are drying, the staff starts the motor 2 16, The motor 2 16 drives the gear 4 17 to rotate, and the gear 4 17 drives the gear 5 18 to rotate through the transmission belt 3 19, and the gear 5 18 drives the rotating disk 24 to rotate, so that the horizontal rotating mechanism on the right side starts to operate, and then the gear 6 21 is rotated through the connection transmission of the transmission rod 20, and the gear 6 21 drives the gear 7 22 to rotate through the transmission belt 4 23, so that the gear 7 22 drives the horizontal rotating mechanism on the left side to start operating. When the rotating disk 24 starts to rotate, the storage plate 25 rotates eccentrically with the rotating disk 24. At this time, since the telescopic connecting rod 27 fixedly connected to the storage plate 25 is restricted by the limiting groove 26, the telescopic connecting rod 27 moves up and down on the limiting groove 26, so that the telescopic connecting rod 27 restricts the storage plate 25 in the horizontal direction to ensure that the items do not fall off. At this time, the storage plates 25 of the two sets of horizontal rotating mechanisms will be close to the drying port 7 accordingly.

[0041] Through the operation of the motor 1 4, the drying port 7 starts to supply hot air to the storage box 2. At the same time, relying on the transmission of the transmission belt 1 9, the gear 3 10 rotates, further pushing the drying port 7 left and right, and then the operation of the motor 2 16 makes the rotating disk 24 rotate, and the rotating disk 24 drives the storage plate 25 to move. At this time, due to the limitation of the limiting groove 26, it is guaranteed that the storage plate 25 is always in a horizontal state. Compared with the traditional device, the device drives the drying mechanism to swing left and right through the swing mechanism, which can not only make the items on the storage plate 25 dry more evenly, but also make better use of hot air, speed up the drying time, and improve the working efficiency. Then, through the cooperation of the transmission mechanism and the horizontal rotating mechanism, the items on the storage plate 25 begin to be alternately dried, so that the items at the bottom are not blocked by the top layer, so that the advantages of blast heating are better utilized, the drying efficiency is improved, and the drying quality is guaranteed.

[0046] When the device starts to run, the heating fan 6 will pass through the filter plate 28, suck in the external air flow, and heat it. At this time, the staff starts the motor three 29, and the rotation of the motor three 29 drives the gear eight 30 to rotate. Through the transmission of the transmission belt five 32, the gear nine 31 starts to rotate, and the gear nine 31 and the gear eight 30 drive the threaded rod 33 to rotate together, so that the brush 34 threadedly connected to the threaded rod 33 starts to move up and down, and the brush 34 and the filter plate 28 contact each other, so that the brush 34 starts to clean the filter plate 28.

[0047] Through the operation of motor three 29, gear eight 30 starts to rotate, and gear eight 30 drives gear nine 31 to rotate together through transmission belt five 32, so that the threaded rods 33 on both sides of the filter plate 28 start to rotate, and further drive the brush 34 threadedly sleeved therewith to move up and down, so as to clean the filter plate 28. The device enables the filter plate 28 to filter the external airflow through the cooperation of the transmission mechanism and the cleaning mechanism, and makes it difficult to be blocked through the cleaning mechanism, thereby preventing external impurities from entering the interior of the drying box 1, thereby interfering with the objects to be detected, and also avoiding the accumulation of external impurities on the filter plate 28, thereby protecting the device and improving the detection quality after drying.

The horizontal rotation mechanism also includes a limiting groove 26 fixedly installed on the bottom of the inner side of the storage box 2, and the limiting groove 26 and the telescopic connecting rod 27 are movably connected.

[0051] When the rotating disk 24 starts to rotate, the storage plate 25 rotates eccentrically with the rotating disk 24. At this time, since the telescopic connecting rod 27 fixedly connected to the storage plate 25 is restricted by the limiting groove 26, the telescopic connecting rod 27 moves up and down on the limiting groove 26, so that the telescopic connecting rod 27 restricts the storage plate 25 in the horizontal direction to ensure that the items do not fall. At this time, the storage plates 25 of the two sets of horizontal rotating mechanisms will approach the drying port 7 accordingly.

[0058] The working principle and use process of this utility model:

[0059] When the items need to be dried, the staff will pull out the storage box 2 inside the drying box 1, and then lay the items to be dried flat on the storage plate 25, and then reset the storage box 2, and then start the motor 14. The operation of the motor 14 drives the heating fan 6 to rotate, so that the heating fan 6 heats the external wind and blows it into the drying port 7. At the same time, the operation of the motor 14 drives the gear 15 to rotate, and the gear 15 drives the gear 2 8 to rotate through the transmission belt 19. The gear 28 drives the gear 3 10 to rotate through the transmission belt 2 11. The rotation of the gear 3 10 rotates the rotating rod 12. When the rotating rod 12 rotates, it pulls the connecting rod 13 to the left or right, so that the connecting rod 13 drives the drying port shell 14 to start swinging left and right, so as to perform all-round hot air drying on the items to be detected in the storage box 2. When the items are drying, the staff starts the motor 2 16, The motor 2 16 drives the gear 4 17 to rotate, and the gear 4 17 drives the gear 5 18 to rotate through the transmission belt 3 19, and the gear 5 18 drives the rotating disk 24 to rotate, so that the horizontal rotating mechanism on the right side starts to operate, and then the gear 6 21 is rotated through the connection transmission of the transmission rod 20, and the gear 6 21 drives the gear 7 22 to rotate through the transmission belt 4 23, so that the gear 7 22 drives the horizontal rotating mechanism on the left side to start operating.

At this time, the storage plates 25 of the two sets of horizontal rotating mechanisms will be close to the drying port 7 accordingly.

[0060] When the device starts to run, the heating fan 6 will pass through the filter plate 28, suck in the external air flow, and heat it. At this time, the staff starts the motor three 29, and the rotation of the motor three 29 drives the gear eight 30 to rotate. Through the transmission of the transmission belt five 32, the gear nine 31 starts to rotate, and the gear nine 31 and the gear eight 30 drive the threaded rod 33 to rotate together, so that the brush 34 threadedly connected to the threaded rod 33 starts to move up and down, and the brush 34 and the filter plate 28 contact each other, so that the brush 34 starts to clean the filter plate 28.
