Description

Technical Field

[0001] The utility model relates to the technical field of drying kiln hot air equipment, in particular to a vertical drying kiln hot air structure. Background Art

[0002] A drying kiln is a large-scale drying equipment used in industrial production. The hot air structure on the drying kiln is transferred to the material through the equipment inside the drying kiln, so that the moisture on the surface of the material evaporates.

This method will cause the temperature of the materials near the air inlet in the drying kiln to be higher, and the temperature on the sides to be lower, resulting in uneven drying of the drying kiln and affecting the drying efficiency of the drying kiln.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 - Figure 5 As shown, in this embodiment, a vertical drying kiln hot air structure includes a drying kiln body 1, an air inlet box 2 is fixedly connected to the middle of the upper end of the drying kiln body 1, a sliding bar 7 is slidably connected to one side of the inner wall of the air inlet box 2, both ends of the sliding bar 7 are fixedly connected to return springs 6, one end of the two return springs 6 is fixedly connected to the inner wall of the air inlet box 2, a pull rod 10 is fixedly connected to the middle of the upper end of the sliding bar 7, and a toggle rod 9 is slidably connected to the outer surface of the pull rod 10, a plurality of rotating blocks 11 are rotatably connected to one side of the upper end of the sliding bar 7, and a gas reversing blade 5 is fixedly connected to one side of the plurality of rotating blocks 11. Both ends of the sheet 5 are rotatably connected to both sides of the inner wall of the air intake box 2. By turning on the driving device 3, the driving gear 4 drives the driven gear 8 to rotate, and the toggle rod 9 pushes the pulling rod 10 to make the sliding bar 7 slide on the inner wall of the air intake box 2. When the toggle rod 9 slides away from the pulling rod 10, the reaction force of the reset spring 6 pushes the sliding bar 7 in the opposite direction, so that the sliding bar 7 can slide back and forth on the inner wall of the air intake box 2. While the sliding bar 7 slides, the rotating block 11 pulls the gas reversing blade 5 to rotate, and changes the direction of the hot air in the heating box 16, so that the material in the drying kiln body 1 is dried without dead angles, thereby improving the drying efficiency of the drying kiln body 1.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a driving device 3 is fixedly installed in the middle of one side of the air intake box 2, and the output end of the driving device 3 is transmission-connected with a driving gear 4. A driven gear 8 is meshed with the outer surface of the driving gear 4, and one side of the driven gear 8 is fixedly connected to one side of the toggle rod 9. The driving gear 4 is smaller in size than the driven gear 8, which has a deceleration effect and prevents the gas reversing blade 5 from rotating too fast.

[0023] like Figure 5As shown, one side of the pull rod 10 is fixedly connected with a reinforcing rib 21, and one side of the reinforcing rib 21 is fixedly connected to one side of the sliding bar 7. Through the structural design of the reinforcing rib 21, the strength of the pull rod 10 can be strengthened to prevent the pull rod 10 from being pushed by the toggle rod 9 for a long time and deformation of the pull rod 10.

[0024] like Figure 4 and Figure 5 As shown, a slide groove 20 is provided at the upper end of the sliding bar 7, and the inner wall of the slide groove 20 is slidably connected to a guide frame 19. One side of the guide frame 19 is fixedly connected to the inner wall of the air intake box 2. Through the structural design of the guide frame 19, the sliding bar 7 can be guided to prevent the sliding direction of the sliding bar 7 from deviating.

[0025] like Figure 2 As shown, a heating box 16 is fixedly connected to one side of the upper end of the drying kiln body 1, and a plurality of heating tubes 12 are fixedly installed inside the heating box 16. The output end of the heating box 16 is fixedly connected to one side of the air inlet box 2, and a hair dryer 13 is fixedly installed at the input end of the heating box 16. By turning on the heating tube 12, the gas in the heating box 16 is heated, and then the hair dryer 13 is turned on to blow hot air into the drying kiln body 1 to dry the material in the drying kiln body 1.

[0026] like Figure 1 - Figure 3 As shown, the lower end of the hair dryer 13 is fixedly connected with a sliding frame 15, and the outer surface of the sliding frame 15 is slidably connected with a sliding box 14. The lower end of the sliding box 14 is fixedly connected to the upper end of the drying kiln body 1, and a damper 17 is fixedly installed inside the sliding box 14. The outer surface of the damper 17 is sleeved with a shock-absorbing spring 18, and the two ends of the shock-absorbing spring 18 are respectively fixedly connected to the sliding frame 15 and one side of the sliding box 14. The vibration generated by the operation of the hair dryer 13 squeezes the sliding frame 15 to drive the damper 17 and the shock-absorbing spring 18 to contract, and when the shock-absorbing spring 18 undergoes elastic deformation, a reaction force is applied to the hair dryer 13 to offset the vibration force generated by the hair dryer 13, thereby achieving a shock-absorbing effect, thereby increasing the service life of the hair dryer 13.

[0027] The utility model provides a vertical drying kiln hot air structure, the specific working principle is as follows:

[0028] When drying the material in the drying kiln body 1, first turn on the heating tube 12 to heat the gas in the heating box 16, then turn on the hair dryer 13 to blow the hot air in the heating box 16 into the drying kiln body 1. When turning on the hair dryer 13, turn on the driving device 3, the driving gear 4 drives the driven gear 8 to rotate, and the toggle rod 9 pushes the pulling rod 10 to make the sliding bar 7 slide on the inner wall of the air intake box 2. When the toggle rod 9 slides away from the pulling rod 10, the reaction force of the reset spring 6 pushes the sliding bar 7 in the opposite direction to achieve the reciprocating sliding of the sliding bar 7 on the inner wall of the air intake box 2. While the sliding bar 7 slides, the rotating block 11 pulls the gas reversing blade 5 to rotate, and changes the direction of the hot air in the heating box 16, so that the material in the drying kiln body 1 is dried without dead angles, thereby improving the drying efficiency of the drying kiln body 1.

[0029] 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.
