Description

Technical Field

[0001] This utility model relates to a drying oven device, and more particularly to a drying oven device for a printing press. Background Technology

[0002] After inkjet printing, the printing materials used on the printing press need to be processed in an oven. Traditional ovens have a small air volume, resulting in slow drying of printed products. The volatile substances such as organic solvents in the ink evaporate slowly and cannot be collected in the oven. During the transfer of printed products, they will evaporate into the surrounding environment, causing serious pollution in the working environment. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a drying oven device that can improve drying efficiency and facilitate the collection of volatile substances.

[0004] To achieve this objective, the structure adopted by this utility model is as follows: a drying oven device, including a movable box and a bottom box, the movable box and the bottom box being arranged opposite each other with a passage in the middle, conveyor rollers arranged on the bottom box, multiple air outlet slots arranged on the movable box, an air inlet pipe, a first air outlet pipe and a second air outlet pipe arranged on the side of the movable box, a partition being arranged inside the movable box to divide the interior of the movable box into front and rear sections, a through hole being provided at the rear of the air outlet slots to connect to the front section of the movable box, the front section of the movable box being connected to the air inlet pipe, two return air slots being provided on the upper and lower sides of the partition, the return air slots being connected to the rear section of the movable box, the rear section of the movable box being connected to the first air outlet pipe and the second air outlet pipe, the first air outlet pipe, the second air outlet pipe and the air inlet pipe being respectively connected to a fan.

[0005] The longitudinal section of the channel is a non-linear trough structure, with the movable box and the bottom box bent along the channel structure on one side facing the channel.

[0006] The air outlet channel is divided into a mesh nozzle air outlet channel and a strip nozzle air outlet channel. The mesh nozzle air outlet channel has mesh nozzles arranged on the side facing the channel; the strip nozzle air outlet channel has long strip nozzles on the side facing the channel.

[0007] Multiple grid-shaped nozzle air outlet slots are set in the middle of the movable box, and multiple strip-shaped nozzle air outlet slots are set on the upper and lower sides of the movable box.

[0008] The strip-shaped nozzles in the top and bottom layers have their long, narrow nozzles facing the center of the movable box.

[0009] The base box and the movable box are connected by a cylinder.

[0010] The upper width of the movable box is greater than the lower width. The first air outlet pipe is connected to the upper side of the movable box, and the second air outlet pipe is connected to the lower side of the movable box.

[0011] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. Hot air is introduced through the air inlet pipe, and the air outlet duct concentrates the air force. The air speed at the outlet of the air outlet duct increases and sprays the printing material in the channel, accelerating the volatilization of volatiles. The return air duct draws the airflow in the channel back to the rear area of ​​the movable box, and then performs secondary heating through the first air outlet pipe and residue treatment through the second air outlet pipe.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figures 1-3The drying oven device shown includes a movable chamber 1 and a base chamber 5, which are arranged opposite to each other with a channel in between for the printing material to pass through. Conveyor rollers are arranged on the base chamber 5, and multiple air outlet slots are arranged on the movable chamber 1, facing the channel to evenly distribute air throughout the channel, allowing volatiles on the printing material to evaporate quickly and improving the drying speed. The movable box 1 is equipped with an air inlet pipe 3, a first air outlet pipe 2, and a second air outlet pipe 4 on its side. Inside the movable box 1, a partition 6 divides the interior into front and rear sections. A through hole is provided at the rear of the air outlet duct to connect to the front section of the movable box. The front section of the movable box is connected to the air inlet pipe 3. Two return air ducts 7 are provided on the upper and lower sides of the partition 6, connecting to the rear section of the movable box. The rear section of the movable box is connected to the first air outlet pipe 2 and the second air outlet pipe 4. The first air outlet pipe 2, the second air outlet pipe 4, and the air inlet pipe 3 are respectively connected to a fan. The air inlet pipe 3 is responsible for introducing heated hot air into the front section of the movable box and distributing it evenly in the channel through the air outlet duct. The first air outlet pipe 2 and the second air outlet pipe 4 recover the hot air mixed with volatiles in the channel. The first air outlet pipe 2 is connected to a secondary heating device for reheating and then sent back into the movable box through the branch pipe 3. The second air outlet pipe 4 is connected to a combustion device to burn the air mixed with high concentrations of volatiles, thus avoiding environmental pollution.

[0020] The longitudinal section of the channel is a non-linear trough structure. The movable box 1 and the bottom box 5 are bent along the structure of the channel on one side to prevent the airflow from traveling in a straight line in the channel, which would make the airflow easily disperse to the surroundings and cause pollution from volatile substances.

[0021] The air outlet channels are divided into mesh nozzle outlet channels 9 and strip nozzle outlet channels 8. The mesh nozzle outlet channels 9 have mesh nozzles arranged on one side facing the channel; the strip nozzle outlet channels 8 have elongated nozzles on one side facing the channel. Multiple mesh nozzle outlet channels 9 are located in the middle of the movable box 1, and multiple strip nozzle outlet channels 8 are located on the upper and lower sides of the movable box 1. The mesh nozzle outlet channels 9 facilitate the formation of a uniformly dispersed hot airflow in the middle section of the channel, while the strip nozzle outlet channels 8 accelerate the airflow towards the channel. Given the non-linear channel structure, this creates airflow obstruction at both ends of the channel, directing the airflow towards the center, further preventing dissipation. The uppermost and lowermost strip nozzle outlet channels 8 have elongated nozzles facing the center of the movable box 1.

[0022] The bottom box 5 and the movable box 1 are connected by a cylinder, so that the channel between the movable box 1 and the bottom box 5 can be expanded or reduced as needed to facilitate material feeding.

[0023] The upper width of the movable box 1 is greater than its lower width. The first air outlet duct 2 is connected to the upper side of the movable box 1, and the second air outlet duct 4 is connected to the lower side of the movable box 1. Since high-concentration residual gas will settle in the lower part of the movable box 1, and the first air outlet duct 4 has a smaller diameter, the narrower space is conducive to the concentrated recovery of high-concentration residual gas. The wider space at the top increases the space for the recovered airflow, ensuring the negative pressure effect in the movable box 1 and avoiding insufficient negative pressure due to insufficient space, which would prevent efficient airflow recovery.

[0024] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
