Description

Technical Field

[0001] The utility model relates to the technical field of drying furnaces, in particular to a fast drying type hot air circulation drying furnace. Background Art

[0002] A drying furnace is a drying equipment that uses combustion of gas, electric heating, etc. as a heat source.

[0003] Most drying furnaces in the prior art use a fixed state to dry the material. This fixed state causes uneven heating of the material during the drying process. Some materials may be over-dried due to exposure to the heat source, while other parts may be under-dried due to being far away from the heat source. This uneven drying state not only affects the final quality of the material, but may also cause unstable product quality and even lead to product scrapping. Secondly, the fixed state drying method limits the full contact between the material and the hot air, reduces the transfer efficiency of heat energy, and thus affects the drying efficiency.

[0006] Preferably, the elastic support assembly includes a push rod, a push plate and a spring. The push rod is connected to the right side of the drying oven through a linear sealed bearing. One end of the push rod is connected to the right side of the slider. The push plate is arranged at the other end of the push rod. A spring is arranged between the push plate and the right side outside the drying oven. The spring is movably mounted on the push rod.

[0007] Preferably, the driving assembly includes a rotating shaft, a motor and two eccentric wheels, the rotating shaft is rotatably connected to the front and rear sides of the support box respectively, the motor is arranged on the rear side outside the support box, and the driving end of the motor is connected to one end of the rotating shaft, and the two eccentric wheels are arranged on the rotating shaft.

[0008] Preferably, the storage rack and the storage door are both made of stainless steel wire mesh.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can reciprocate the push plate through the setting of the motor and the cam, and due to the elastic effect of the spring, the push plate will drive the placement rack to vibrate horizontally, and the vibration makes the material in the placement rack more evenly distributed and turned over, ensuring that the material can be evenly heated in the drying furnace, and each part of the material can be fully dried, thereby greatly improving the drying efficiency and drying quality of the product. Secondly, this vibration promotes the circulation of air inside the drying box. When the material vibrates in the placement rack, it will drive the surrounding air flow, forming a more uniform hot air circulation, which not only accelerates the evaporation rate of water in the material, but also ensures that the temperature in the drying furnace is more uniform, further improving the drying efficiency. Finally, due to the uniform distribution and turning of the material and the improvement of air circulation in the drying box, the material can reach the ideal drying state more quickly during the drying process.

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.

[0015] See also Figure 1-3The utility model provides a fast drying hot air circulation drying furnace, including a drying furnace 1, three placement components 2 are arranged in the drying furnace 1, and the three placement components 2 are arranged in sequence from top to bottom to ensure that the hot air in the drying furnace 1 is fully circulated, the placement component 2 includes two linear guide rods 21, a slider 22, a placement rack 23 and a storage door 24, the two ends of the two linear guide rods 21 are respectively connected to the left and right sides of the drying furnace 1, the slider 22 is slidably connected to the two linear guide rods 21, the placement rack 23 is arranged on the top of the slider 22, the front side of the placement rack 23 is opened, and the storage door 24 is movably connected at the opening, the slider 22 is connected to an elastic support component 3, a support box is arranged on the right side outside the drying furnace 1, and a driving component 4 is arranged in the support box.

[0016] Specifically, the elastic support assembly 3 includes a push rod 31, a push plate 32 and a spring 33. The push rod 31 is connected to the right side of the drying oven 1 through a linear sealed bearing. One end of the push rod 31 is connected to the right side of the slider 22. The linear bearing ensures the stability and sealing of the push rod 31 when pushing the placement rack 23. The push plate 32 is arranged at the other end of the push rod 31. A spring 33 is arranged between the push plate 32 and the right side outside the drying oven 1. The spring 33 is movably mounted on the push rod 31.

[0017] Specifically, the driving assembly 4 includes a rotating shaft 41, a motor 42 and two eccentric wheels 43. The rotating shaft 41 is rotatably connected to the front and rear sides of the support box respectively. The motor 42 is arranged on the rear side outside the support box, and the driving end of the motor 42 is connected to one end of the rotating shaft 41. The two eccentric wheels 43 are arranged on the rotating shaft 41.

[0018] Specifically, the placement rack 23 and the storage door 24 are both made of stainless steel wire mesh, which has good ventilation and can ensure that the material obtains uniform heat distribution during the drying process, thereby improving the drying efficiency and quality.

[0019] Working principle: When it is necessary to dry the material, the operator will first open the door of the drying furnace 1 and the storage door 24 of the placement rack 23, and then neatly place the material to be dried at the designated position in the placement rack 23. When the material is placed, the operator closes the storage door 24 and the door of the drying furnace 1 to ensure that the heat does not leak out, and starts the drying furnace 1 and the driving component 4. The core component of the driving component 4 is the motor 42. When the motor 42 starts and starts to rotate, it will drive the rotating shaft 41 and the eccentric wheel 43 connected thereto to rotate. As the eccentric wheel 43 rotates, it will periodically squeeze the push plate 32 and the push rod 31. The distance between the eccentric wheel 43 and the push plate 32 will change continuously during the rotation process, thereby realizing the push plate 32. Squeezing and releasing, when the eccentric wheel 43 squeezes the push plate 32, the push plate 32 will push the push rod 31 to move to the left, and the spring 33 will be compressed at the same time, and when the eccentric wheel 43 releases the push plate 32, the elastic action of the spring 33 will cause the push rod 31 and the push plate 32 to return to their original positions quickly. This periodic action of squeezing and releasing makes the push plate 32 and the placement rack 23 connected thereto vibrate laterally along the linear guide rod 21. Since materials are placed in the placement rack 23, the materials will also vibrate with the placement rack 23. The vibration makes the materials in the placement rack 23 more evenly distributed and turned over, ensuring that the materials can be evenly heated in the drying furnace 1, and each part of the materials can be fully dried, thereby greatly improving the drying efficiency and drying quality of the products.
