Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of environmental protection processing equipment, in particular to an integrated frame type wind reduction oven system. Background Art
[0002] At present, the printing machine adopts the full-inlet and full-exhaust heat pump system. The characteristics of the heat pump are that it occupies a small area and the distance between the color groups is relatively compact; however, the exhaust volume of this system is large, the exhaust concentration is low, and the power consumption is high. Under the conditions of fixed vehicle speed and exhaust volume, the color group with a small printing volume will still have a large exhaust volume under the operation of this system, and even the VOC concentration in the exhaust of the full-page color group is not high.
[0003] Although low-concentration production emissions have advantages in terms of safety, in terms of energy consumption, the more exhaust air there is, the higher the energy consumption of the oven. High exhaust air will lead to low VOC concentration, which is not conducive to the self-circulation of RTO. The higher the energy consumption of the RTO equipment, the higher the cumulative energy consumption of the total production equipment.
[0004] Under this circumstance, it is urgent to develop an integrated frame type reduced wind oven system. Utility Model Content

[0007] As a further improvement of the above technical solution:
[0008] Preferably, the structure of the outer frame is: a frame structure formed by welding a plurality of square tubes, and the frame structure is used for fixing the sealing plate.
[0009] Preferably, a channel steel structure is laid under each bearing point of the wind reduction module located in the outer frame, and the channel steel structure is welded to the outer frame.

[0015] The beneficial effects of the utility model are as follows:
[0016] The utility model has a compact structure. The air coming out of the exhaust pipe of the printing machine is divided into two paths. One path is blocked by an additional wind baffle and then discharged along the outlet pipe. The other path is mixed with the fresh air sent from the fresh air pipe in the air mixing box to form circulating air. The circulating air passes through the heat exchanger and the return air pipe in turn and is sent to the printing machine through the circulating fan. By increasing the circulating air volume and reducing the exhaust of a single color group, the exhaust volume of the entire production line is reduced, achieving the purpose of reducing air and increasing concentration.
[0017] The utility model also has the following advantages:
