Abstract
The invention relates to the technical field of accessories of printing machines, in particular to a circulating device for an oven of a printing machine. The circulating device comprises a draught fan, a heater and the oven which are sequentially connected; the circulating device further comprises a circulating pipe, one end of the circulating pipe is connected with an outlet of the oven, the other end of the circulating pipe is connected with an inlet of the draught fan, and a thermal insulation material is arranged on the outer layer of the circulating pipe; and the circulating pipe is provided with a first valve and a check valve, an emergency access is arranged at an inlet of the first valve, and a second valve is arranged on the emergency access. By means of the arrangement of the circulating pipe, circulating flowing of hot air is achieved, heat transmission is accelerated, waste heat can be used in a circulating manner for drying, and the drying efficiency is improved. Meanwhile, the emergency access is arranged on the circulating pipe, and safe running of the device can be guaranteed.
Description
Technical field
The present invention relates to printing machine accessory technical field, be specifically related to a kind of press oven EGR.
Background technology
At printing technology, some printed matter needs to carry out drying and processing after printing completes, and the oven dry of current press printing product adopts baking oven usually.The general energy consumption of heated-air drying equipment is larger.Generally, heated-air drying energy consumption accounts for more than 80% of whole printing-flow energy consumption, dry run discharge hot gas in store a large amount of heat energy, from baking oven air exhaust passage discharge hot gas not only to environmental effects, also cause energy waste to a certain extent.This part heat energy is directly discharged in air and is wasted, and causes certain economic loss to enterprise.
Summary of the invention
The object of the present invention is to provide a kind of energy-conserving and environment-protective, security of operation, press oven EGR simple to operate.
In order to achieve the above object, the technical solution used in the present invention is: a kind of press oven EGR, comprise the blower fan, heater and the baking oven that connect successively, also comprise circulation pipe, one end of described circulation pipe is connected with the outlet of baking oven, the other end is connected with the entrance of blower fan, and circulation pipe skin is provided with insulation material; Circulation pipe is provided with the first valve and non-return valve, is provided with emergency access in the porch of the first valve, and described emergency access is provided with the second valve.
A kind of press oven EGR as above, illustrate further into, described baking oven is provided with thermometer.
A kind of press oven EGR as above, illustrate further into, described insulation material is heat-preservation cotton.
A kind of press oven EGR as above, illustrate further into, described heater is electrical heating wire.
A kind of press oven EGR as above, illustrate further into, described blower fan is provided with frequency converter.
The invention has the beneficial effects as follows: 1, by arranging circulation pipe, achieving circulating of hot blast, the transmission of accelerated heat also can recycle waste heat dries, and improves drying efficiency.2, on circulation pipe, be provided with emergency access, the safe operation of this device can be ensured.3, outside circulation pipe, be provided with insulation material, the loss of heat can be reduced, improve energy utilization rate.4, blower fan adopts Frequency Converter Control, can adjust the size of air quantity at any time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, blower fan; 2, heater; 3, baking oven; 4, circulation pipe; 5, insulation material; 6, the first valve; 7, non-return valve; 8, emergency access; 9, the second valve; 10, thermometer.
Detailed description of the invention
Below in conjunction with accompanying drawing, elaboration detailed is further done to the present invention.
As shown in Figure 1, a kind of press oven EGR provided by the invention, comprises the blower fan 1, heater 2 and the baking oven 3 that connect successively, and blower fan 1 outlet is connected with the entrance of heater 2, and the outlet of heater 2 is connected with the entrance of baking oven 3.Described heater 2 preferred version is electrical heating wire, and blower fan 1 is designed with frequency converter, is controlled the power output of blower fan 1 by frequency converter, thus can adjust the air force of blower fan 1, regulates voluntarily according to environment for use.
Also comprise circulation pipe 4, one end of described circulation pipe 4 is connected with the outlet of baking oven 3, and the other end is connected with the entrance of blower fan 1, circulation pipe 4 skin is provided with insulation material, and preferred version is heat-preservation cotton, outside circulation pipe 4, design insulation material, the loss of heat can be reduced, improve energy utilization rate.
Circulation pipe 4 is provided with the first valve 6 and non-return valve 7; non-return valve 7 is between the first valve 6 and the entrance of blower fan 1; non-return valve 7 allows hot blast from the outlet flow of baking oven 3 to the entrance of blower fan 1, can not make reverse air flow, thus protect security of operation of the present invention.When normally running, opening the first valve 6 and making hot blast from circulation pipe 4, flow to the entrance of blower fan, thus achieving circulating of hot blast, the transmission of accelerated heat also can recycle waste heat dries, improve drying efficiency, saved the energy, reduced entreprise cost.
In the porch of the first valve 6, namely between the outlet of baking oven 3 and the first valve 6, circulation pipe 4 is provided with emergency access 8, and described emergency access 8 is provided with the second valve 9.Emergency access 8 act as when there is misoperation, the emergency exit of hot blast.Such as, when blower fan 1 occurs abnormal, at this moment open the second valve 9 on emergency access 8, close the first valve 6, hot blast is flowed out from emergency access 8.On circulation pipe 4, designing emergency access 8 by adopting, some abnormal conditions of this device can be dealt with, ensure that safe operation of the present invention.
Baking oven 3 is provided with thermometer 10, the temperature in energy handled easily personnel real-time monitored baking oven 3.Structure of the present invention is simple, security of operation.
The present invention is not limited to above-mentioned example, and in claims limited range of the present invention, the various distortion that those skilled in the art can make without creative work or amendment are all by the protection of this patent.
