Description

Technical Field

[0001] This utility model belongs to the field of ventilation structure, specifically relating to the ventilation structure of an electric heating blower drying oven. Background Technology

[0002] The ventilation structure of the electric heating forced-air drying oven is the core system for realizing air circulation, heat transfer and moisture removal inside the oven. Its design directly affects the temperature uniformity and drying efficiency inside the oven.

[0003] In existing technologies, if the filter screen is installed in a simple way, it is not easy to replace. There is a lack of a clear heating air delivery channel. The heating air diffuses randomly inside the equipment. The air outlet is directly facing the shelf, and the high-speed airflow blows directly onto the sample surface. Fresh air enters from the air inlet and is discharged directly from the air outlet without being fully mixed with the air in the chamber. Utility Model Content

[0004] To overcome the problems in existing technologies, such as the filter screen being easy to install and difficult to replace, lacking a clear heating delivery channel, allowing heating to diffuse randomly inside the equipment, and the air outlet facing the shelf, resulting in high-speed airflow blowing directly onto the sample surface, fresh air entering from the air inlet is not fully mixed with the air inside the chamber before being directly discharged from the air outlet, a ventilation structure for an electric heating forced-air drying oven is proposed.

[0005] The technical solution of this utility model is as follows: the ventilation structure of the electric heating blower drying oven includes a storage box and a stirring mechanism provided on both sides of the inner wall of the storage box, a conveying mechanism provided at one end of the inner wall of the storage box, and a filtering mechanism provided at the upper end of the storage box.

[0006] Furthermore, the stirring mechanism includes support plates fixed to both sides of the inner wall of the storage box. Two first slots are respectively opened in the vertical direction at the ends of the two support plates that are close to each other. An electric cylinder is fixed to the inner wall of the first slot. The output end of the electric cylinder is slidably installed on one end of the side wall of the rotating plate, and the other end of the rotating plate is rotatably installed on the side wall of the support plate.

[0007] Furthermore, the conveying mechanism includes a second slot through the upper end of the storage box, a conveying pipe fixed to one end of the inner wall of the storage box, auxiliary pipes fixed to both sides of the conveying pipe, two third slots through the horizontal direction at one end of the conveying pipe, a fourth slot through the upper end of the auxiliary pipe, and a fan fixed to the inner wall of the conveying pipe.

[0008] Furthermore, the filtration mechanism includes two limiting blocks fixed to the upper end of the storage box. The two limiting blocks are located on both sides of the second slot, and a fifth slot is opened on one side of the two limiting blocks. A sliding block is slidably installed on the inner wall of the fifth slot, and a filter screen is fixedly connected to one end of the two sliding blocks.

[0009] Furthermore, the third slot consists of multiple holes, which are evenly distributed in the vertical direction, and the diameter of the holes gradually increases.

[0010] Furthermore, the delivery pipe and the auxiliary pipe are interconnected.

[0011] Furthermore, the upper ends of the limiting block and the sliding block are provided with screw holes, and the bolts pass through the inner walls of the sliding block and the limiting block.

[0012] The beneficial effects of this utility model are as follows: The electric cylinder drives the rotating plate to rotate inside the storage box, disrupting the internal airflow and breaking the fixed ventilation path, effectively preventing the formation of ventilation dead zones and ensuring more uniform drying of items. By designing a third slot with a diameter that gradually increases vertically, the warm air delivered into the storage box in the vertical direction is basically uniform, avoiding the problem of local over-drying. Through the cooperation of sliding blocks, the fifth slot, limit blocks, and bolts, the filter screen is firmly fixed in the installation position, preventing the filter screen from loosening or shifting, ensuring the stability of the filtration effect and the durability of the filter screen. The directional path of the filter screen, the second slot, the conveying pipe, the third slot, and the storage box provides a clear channel with stronger sealing, reducing the meaningless diffusion of warm air during the transportation process, reducing heat loss, and improving the drying efficiency per unit of heat.

[0022] In use, first place the item inside the storage box 1. Based on the sliding block 43 and the fifth slot 42, install the filter 44 on the inner wall of the limiting block 41. Fix the limiting block 41 and the sliding block 43 together with bolts. Then turn on the fan 36 to send warm air through the filter 44 and into the delivery pipe 32 through the second slot 31. The warm air moves into the storage box 1 through the third slot 34. Since the diameter of the third slot 34 gradually increases in the vertical direction, the warm air delivered into the storage box 1 in the vertical direction is basically uniform, which will not cause the item to be too dry in some areas. Then turn on the electric cylinder 23. The output end of the electric cylinder 23 pushes one end of the rotating plate 24 to move back and forth. Since the other end of the rotating plate 24 is rotatably installed on the side wall of the support plate 21, the rotating plate 24 will rotate inside the storage box 1, disturbing the warm air inside the storage box 1 and preventing dead corners from appearing inside the storage box 1.

[0023] Please see Figure 3 In this embodiment, the stirring mechanism 2 includes a support plate 21 fixedly connected to both sides of the inner wall of the storage box 1. Two first slots 22 are respectively opened in the vertical direction at the ends of the two support plates 21 that are close to each other. An electric cylinder 23 is fixedly connected to the inner wall of the first slot 22. The output end of the electric cylinder 23 is slidably installed on one end of the side wall of the rotating plate 24. The other end of the rotating plate 24 is rotatably installed on the side wall of the support plate 21. The electric cylinder 23 drives the support plate 21 to move, disturbing the heating inside the storage box 1.

[0024] Please see Figure 4 In this embodiment, the conveying mechanism 3 includes a storage box 1 with a second slot 31 extending through the upper end. A conveying pipe 32 is fixedly connected to one end of the inner wall of the storage box 1. Auxiliary pipes 33 are fixedly connected to both sides of the conveying pipe 32. Two third slots 34 are extended through the horizontal direction at one end of the conveying pipe 32. A fourth slot 35 is extended through the upper end of the auxiliary pipe 33. A fan 36 is fixedly connected to the inner wall of the conveying pipe 32. The fan 36 conveys warm air to the lower end of the conveying pipe 32.

[0025] Please see Figure 5 and Figure 6In this embodiment, the filter mechanism 4 includes two limiting blocks 41 fixedly connected to the upper end of the storage box 1. The two limiting blocks 41 are respectively located on both sides of the second slot 31. A fifth slot 42 is opened on one side of the two limiting blocks 41. A sliding block 43 is slidably installed on the inner wall of the fifth slot 42. A filter screen 44 is fixedly connected to one end of the two sliding blocks 43. The filter screen 44 screens out the dust in the heating system.

[0026] Please see Figure 4 In this embodiment, the third slot 34 consists of multiple holes, which are evenly laid out in the vertical direction. The diameter of the multiple holes gradually increases, so as to reasonably control the amount of heating air discharged.

[0027] Please see Figure 4 In this embodiment, the delivery pipe 32 and the auxiliary pipe 33 are interconnected, and the heating air is transported from the delivery pipe 32 to the interior of the auxiliary pipe 33.

[0028] Please see Figure 4 In this embodiment, the upper ends of the limiting block 41 and the sliding block 43 are provided with screw holes, and the bolts pass through the inner walls of the sliding block 43 and the limiting block 41, and the bolts fix the sliding block 43 and the limiting block 41 together.

[0029] Working principle: First, place the item inside the storage box 1. Based on the sliding block 43 and the fifth slot 42, install the filter 44 on the inner wall of the limiting block 41. Fix the limiting block 41 and the sliding block 43 together with bolts. Then, turn on the fan 36 to send warm air through the filter 44 and into the delivery pipe 32 through the second slot 31. The warm air moves into the storage box 1 through the third slot 34. Since the diameter of the third slot 34 gradually increases in the vertical direction, the warm air delivered into the storage box 1 in the vertical direction is basically uniform, which will not cause the item to be too dry in some areas. Then, turn on the electric cylinder 23. The output end of the electric cylinder 23 pushes one end of the rotating plate 24 to move back and forth. Since the other end of the rotating plate 24 is rotated and installed on the side wall of the support plate 21, the rotating plate 24 will rotate inside the storage box 1, disturbing the warm air inside the storage box 1 and preventing dead corners from appearing inside the storage box 1.
