The five groups of heat using pipelines applying the same principle are arranged in different areas of the press according to the process requirements of the continuous press for pressing plates, each group of heat using pipelines is capable of independently controlling the heating process of the corresponding area, and the temperature of a hot press plate of the continuous press can be controlled within different ranges, so that the requirements of plate pressing temperature curves are met.
Description
Technical field
The utility model relates to the continuous press of wood based panel equipment, is a kind of deep fat secondary cycle system that is used for continuous press heating and temperature control particularly.
Background technique
In Wood-based Panel Production equipment; Represent the continuous press production line of wood based panel equipment international most advanced level to have manufacturing efficiency height, energy-conservation, the good product quality of economizing raw material, production, advantage such as complete in specifications, be specially adapted to mass production and the slim MDF of processing, PB, OSB sheet material.Continuous press full name is claimed the rolling friction flat-crushing type continuous press, is product the most popular in the world at present, most significant end.Its working principle is to send having executed the mat formation slab of moulding of glue into the compacting of heating in this machine, makes the adhesive curing in the slab, forms the artificial board of certain intensity and specification.In the continuous press production run, need carry out the heating of zones of different to the last lower hot pressing board that reaches more than 30 meters, temperature control is to satisfy the temperature process curve needs of pressed sheet.
The model utility content
In order to address the above problem, the utility model provides a kind of deep fat secondary cycle system that is used for continuous press heating and temperature control.
The utility model is that the technological scheme that its technical problem of solution is adopted is,
The deep fat secondary cycle system that is used for continuous press heating and temperature control; Comprise the inflow pipeline of carrying the boiler high temperature conduction oil; And the oil returning tube that conduction oil is back to boiler; Also comprise and use pipe line, saidly be connected in side by side between inflow pipeline and the oil returning tube, saidly be provided with 5 groups with pipe line with pipe line.
Concrete; Saidly comprise electric control valve and oil circulating pump with pipe line; Electric control valve one end is connected in inflow pipeline through hand stop valve, and the other end connects oil circulating pump, is connected to oil returning tube behind the hot platen of the output pipe of oil circulating pump through continuous press.
In addition, be connected with differential pressure transmitter between said inflow pipeline and the oil returning tube, said output pipe is connected in system's draining pipeline through normally closed cut-off valve.
After the motorized adjustment opening of valves, the conduction oil of high temperature is inhaled in the oil circulating pump, sends into the hot platen of continuous press, is back to heating again in the boiler through the conduction oil behind the hot platen through return line, forms complete Circulation and Hot Oil Spray.
Temperature transducer is housed on the hot platen, and actual temperature value is read through temperature transducer in the electrical control center, relatively the value of process curve setting; If at this moment the temperature that true temperature is set less than needs just controls electric control valve, strengthen its aperture; The amount that flows into the high temperature heat conductive oil in the press will increase, and the true temperature of pressing plate will raise, otherwise; When temperature was higher than setting value, electric control valve will be controlled in the electrical control center, reduced its aperture; At this moment the high temperature heat conductive oil that is inhaled into will reduce, and the heat of sending in the press reduces, and temperature will reduce; Such cyclic process is controlled near the setting value temperature of hot platen, accomplishes the process to platen heating and temperature control.
The beneficial effect of the utility model is; This circulatory system is according to continuous press pressed sheet arts demand; The zones of different of press establish altogether 5 groups of principles identical use pipe line; Can control the heating process of respective regions separately with pipe line for every group, can continuous press hot platen temperature be controlled in the different scopes, reach the needs of the temperature curve of sheet material compacting.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The deep fat secondary cycle system that is used for continuous press heating and temperature control that the utility model proposes includes the inflow pipeline 100 that is used to carry the boiler high temperature conduction oil; And the oil returning tube 200 that conduction oil is back to boiler; Also comprise and use pipe line, saidly be connected in side by side between inflow pipeline 100 and the oil returning tube 200 with pipe line.
According to the temperature process curve of pressed sheet as shown in Figure 5, the hot platen of corresponding zones of different is provided with 5 groups and uses pipe line, respectively five districts, first district to the in the corresponding diagram 5.
Saidly comprise electric control valve 320 and oil circulating pump 330 with pipe line; Electric control valve 320 1 ends are connected in inflow pipeline 100 through hand stop valve 310; The other end connects oil circulating pump 330, is connected to oil returning tube 200 behind the hot platen 340 of the output pipe of oil circulating pump 330 through continuous press.Be connected with differential pressure transmitter 110 between said inflow pipeline 100 and the oil returning tube 200, said output pipe is connected in system's draining pipeline 400 through normally closed cut-off valve.
After the motorized adjustment opening of valves, the conduction oil of high temperature is inhaled in the oil circulating pump, sends into the hot platen of continuous press, is back to heating again in the boiler through the conduction oil behind the hot platen through return line, forms complete Circulation and Hot Oil Spray.
Temperature transducer is housed on the hot platen, and actual temperature value is read through temperature transducer in the electrical control center, relatively the value of process curve setting; If at this moment the temperature that true temperature is set less than needs just controls electric control valve, strengthen its aperture; The amount that flows into the high temperature heat conductive oil in the press will increase, and the true temperature of pressing plate will raise, otherwise; When temperature was higher than setting value, electric control valve will be controlled in the electrical control center, reduced its aperture; At this moment the high temperature heat conductive oil that is inhaled into will reduce, and the heat of sending in the press reduces, and temperature will reduce; Such cyclic process is controlled near the setting value temperature of hot platen, accomplishes the process to platen heating and temperature control.
