Abstract

The utility model provides a heating device for an artificial plate hot-press machine, which uses an electric heater as heat source and uses heat conducting oil as heat conducting fluid medium. Thus, the utility model has no need of a high-pressure steam boiler and steam supplying pipelines, and has the advantages of investment saving, compact structure, high heat efficiency and convenient operation and control. Heating temperature of a heat press board can be controlled within the range from 50 DEG C to 300 DEG C.

Description

Heating device for artificial plate hot-press machine

The utility model relates to wood processing machinery, specifically a kind of heater of man-made board hot-pressing machine.

Hot press is to be used in the wood-based plate operation multilayer blank (or particle) under the effect of adhesive, form a kind of equipment of thicker integral blank by the heating pressurization, its main working parts is a heating platen, several piece even tens of heating platens are often arranged on the hot press, these heating platens can move up and down under the effect of mechanical force, to being filled in two multilayer blank (or particle) pressurizations between heating platen, in pressurization, heating platen itself is again as a heat conductor, high temperature heat is passed to the pressurized blank, multilayer blank (or particle) between two pressing plates is heated again in pressurized, what supply with the heating platen high temperature heat in the existing hot press generally is the high temperature and high pressure steam that transports with steam boiler, this is relatively to be suitable for for the enterprise that has a large amount of hot presses, and for small-scale wood processing enterprise, hot press quantity is few, moves discontinuous carrying out, and it is big and the steam boiler utilization rate is low then just to exist the steam boiler one-time investment, shortcomings such as energy consumption is big.

The purpose of the utility model is to overcome the deficiency of above technology, and a kind of investment is little, the thermal efficiency is high, use hot press heater flexibly and provide.

The purpose of this utility model is achieved in that a kind of man-made board hot-pressing machine heater, comprise electric heater (1), main fuel tank (2), conduction oil (3), main oil inlet pipe (4), an oil inlet hose (5), heating platen (6), a fuel-displaced flexible pipe (7), main flowline (8), oil pump (9) auxiliary fuel tank (10), it is characterized in that its thermal source is electric heater (1), the heat-conducting flow body medium is conduction oil (3).During the utility model work, by the electric heater (1) that is located in the main fuel tank (2) conduction oil (3) in the main fuel tank (2) is directly heated, conduction oil (3) through heating flows out through main oil inlet pipe (4), and be assigned to the oil inlet hose (5) that is connected on each heating platen (6), flow through in the fluid cavity of conduction oil (3) in each heating platen (6), and after giving heating platen (6) with thermal energy transfer, flow out through each fuel-displaced flexible pipe (7), import main flowline (8), and then draw back main fuel tank (2) through oil pump (9) and reheat, so just can continuously each heating platen (6) be heated to needed operating temperature.

Advantage of the present utility model is:

1) whole heater cost ratio is provided with steam boiler and jet chimney is much smaller, thus productive investment few, go up detective.

2) starting is fast, can start separately and stop, and is strong to production process adaptability.

3) heat supply pipeline weak point, and thermal medium is not discharged, so thermal energy consumption is few, the thermal efficiency is high.

The utility model is further described below in conjunction with drawings and Examples:

Accompanying drawing is the utility model principle sketch.

As shown in drawings, electric heater (1) and main fuel tank (2) are integrated, conduction oil (3) is housed in the main fuel tank (2), electric heater (1) directly is inserted in the conduction oil 3 and to conduction oil (3) and directly heats, the power of electric heater (1) is controlled (automatic control or manual control), with the operating temperature of the conduction oil (3) that guarantees output in 50 ℃～300 ℃ scopes.Conduction oil (3) through heating is exported from main fuel tank (2) by main oil inlet pipe (4), and be assigned to each oil inlet hose (5), import in the internal cavities of each heating platen (6) by each oil inlet hose (5), propping up oil inlet hose (5) must be the flexible pipe of metal or nonmetal system or the steel pipe that has turning joint, its reason is because heating platen (6) need move up and down in the course of the work, have only with flexible pipe or the steel pipe that has turning joint and join with it, could guarantee its motion freely, heating platen (6) is the critical piece of heating platen, and a hollow inner chamber that can pass through the fluid thermal medium is all arranged.In the utility model, medium by its inner chamber is the conduction oil (3) of high temperature, conduction oil (3) is in flowing through the process of its inner chamber, to give heating platen (6) entrained thermal energy transfer, heating platen (6) temperature is raise, thermal capacity increases, enter the duty of pressurized, heated, conduction oil (3) is after passing to heating platen (6), enter main flowline (8) through fuel-displaced flexible pipe (a 7) outflow, the end of main flowline (8) is connected on the entrance point of oil pump (9), make conduction oil (3) after oil pump (9) pressurization, send main fuel tank (2) back to, so just finished the circulation of a heat energy transmission.This device is running continuously, and then this thermal cycle is also just being carried out continuously.Conduction oil (3) will expand after being heated in the device, in running owing to can leak, also need to replenish oil mass, an auxiliary fuel tank (10) in parallel between main oil inlet pipe 4 and main flowline (8) just for this reason, its effect is exactly the oil mass that stores unnecessary oil mass and additional deficiency.

Whole heater can be designed to control automatically, also can be by Artificial Control, because it adopts electrical heating, conduction oil is again ceaselessly periodic duty, and so its compact conformation, energy loss is few in the heat transfer process, thus thermal efficiency height, and pollution-free.
