Description
Technical Field
The invention particularly relates to a natural gas heating vertical foaming furnace.
Background
In PE, PP, polyethylene, polypropylene film foaming field, the foaming furnace that generally uses all is electric heating, especially do not use the gas furnace in the aspect of the great perpendicular foaming furnace of the degree of difficulty, because the degree of difficulty is too big, the gas is difficult to the controlled temperature, so domestic all adopts the electric heating mode in perpendicular foaming furnace field, the biggest problem of electric heating mode is influenced by unit area electric heat energy surface power, can not unrestricted increase power, also influence the promotion of productivity, the unit output of general electric heating furnace is about 8m per minute, the development of production has been restricted greatly.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a natural gas heating vertical foaming furnace. The invention has the characteristics of low energy consumption and high productivity.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a natural gas heating vertical foaming furnace comprises a horizontal preheating section and a vertical foaming furnace section; symmetrical horizontal section air inlets are formed in the vertically symmetrical two sides of the horizontal preheating section; placing a master slice on the left side of the horizontal preheating section; the right end of the horizontal preheating section is connected with the vertical foaming furnace section; the master slice passes through the horizontal preheating section and then vertically and downwards passes through the vertical foaming furnace section; a left vertical air inlet blower and a right vertical air inlet blower are arranged on two side edges of the vertical foaming furnace section; the left vertical air inlet air feeder and the right vertical air inlet air feeder are respectively provided with an air inlet valve; auxiliary electric heat is provided between the adjacent vertical air inlet air blowers.
Further, the mother sheet passes through the horizontal preheating section and the vertical foaming furnace section, and then the finished product is output at the output end of the vertical foaming furnace.
Has the advantages that: the invention provides a natural gas heating vertical foaming furnace, which can directly heat air by using fuel gas to achieve the aim of foaming, can basically achieve the yield of about 16 m/min, which is one time of the original yield through tests at present, and uses only one third of the original energy.

Detailed Description
The invention is illustrated below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
A natural gas heating vertical foaming furnace is shown in figures 1 and 2 and comprises a horizontal preheating section (1) and a vertical foaming furnace section (2); symmetrical horizontal section air inlets (5) are arranged at the upper and lower symmetrical sides of the horizontal preheating section; a master slice (3) is placed at the left side of the horizontal preheating section (2); the right end of the horizontal preheating section (1) is connected with the vertical foaming furnace section (2); the master slice (3) passes through the horizontal preheating section (1) and then vertically and downwards passes through the vertical foaming furnace section (2); a left vertical air inlet blower (6) and a right vertical air inlet blower (7) are arranged on two side edges of the vertical foaming furnace section (1); an air inlet valve (8) is respectively arranged at the left side vertical air inlet air feeder (6) and the right side vertical air inlet air feeder (7); auxiliary electric heat (9) is provided between the adjacent vertical air inlet air blowers.
And the master slice (3) passes through the horizontal preheating section (1) and the vertical foaming furnace section (2), and is output at the output end of the vertical foaming furnace section (2) to be manufactured into a finished product (4).
As shown in fig. 2, one end of the auxiliary electric heater (9) is also provided with an outlet (10) for circulating air.
The invention adopts a natural gas combustion furnace to directly heat air, and convects with hot air of a PE and PP film master slice to enable the master slice to quickly absorb heat and foam, a tunnel light combustion furnace adopts PID stepless fire regulation, secondly, air quantity and air pressure stepless speed regulation, and the most main part is secondary regulation of an air outlet and an air outlet direction, in addition, a similar circulating air duct system is arranged in each section (three sections) of temperature control area to enable the temperature of each section to be kept within +/-1 ℃, the temperature difference of each section is up to 100 ℃, all fans, air door combustors, secondary regulators and the circulating air duct system are controlled by a computer system, and an independent set of algorithm is formed to dynamically adjust, so as to realize the purpose of temperature control.
Claims (2)
