Further, the method comprises the steps of;
In an alternative embodiment, the exhaust control member 53 includes a control housing 531 and a control housing 54, the inner wall of the control housing 54 is slidably tangent to and sealed with the outer end surface of the control housing 531, the inner space of the control housing 54 is provided with hydraulic oil 541, the bottom end of the control housing 531 is welded to the outer surface of the oven door 2, an air inlet through hole 5312 is formed in the bottom of the control housing 531, the air inlet through hole 5312 can be communicated with the air outlet through hole 21 formed in the oven door 2, a movable space 5311 is formed in the control housing 531, a piston 532 is slidably tangent to and sealed at the movable space 5311 of the control housing 531, a plug 533 is fixedly connected to the top end of the piston 532, a large-up and small-down trumpet-shaped through hole 5313 is formed in the top end of the control housing 531, the inner space of the control housing 54 can be communicated with the movable space 5311 of the control housing 531 through the trumpet-shaped through hole 5313, the cross-sectional diameter of the plug 533 is smaller than the cross-sectional diameter of the piston 532, and a second compression spring 534 is fixedly connected between the bottom surface of the piston 532 and the bottom surface of the movable space 5311 of the control housing 531;
The two ends of the double-hook tension spring 61 are provided with tension spring brackets 62, one tension spring bracket 62 is fixed on the outer surface of the furnace body 1, the other tension spring bracket 62 is fixed on the outer surface of the shaft connecting plate 4, when the pressure in the furnace body 1 is not released and the furnace door 2 is rotated, the gas pressure on the inner side of the furnace body 1 can push the furnace door 2 to rotate around the hinge to open suddenly, thereby causing a safety accident, after the safety exhaust device 5 is arranged, the furnace door 2 can not be opened suddenly under the action of the gas pressure in the furnace, but gradually and rapidly open the furnace door 2 along with the gradual reduction of the gas pressure in the furnace body 1, thereby realizing the purposes that the gas discharge amount error is in a safe range in unit time in the process of exhausting, specifically, when the furnace door 2 is just opened, the gas pressure in the furnace body 1 is larger, the gas flow rate is also large, so that the total amount of the gas discharged in the unit time is larger, and after the furnace door 2 is opened for a period of time, the gas pressure in the furnace body 1 is smaller, the gas flow rate is lower, so that the total amount of the gas discharged in the unit time is less, so that when the gas flow rate in the furnace door 2 is opened, the whole time is reduced, and the gas flow rate is increased, and the total amount is increased in the whole time, and the whole time is opened, and the gas gap is opened, and the whole time is reduced, and the gas gap is the time, and the time is opened 2 is opened, and the time is 1, the total amount of gas flowing out of the furnace body 1 has small error, so that the safety of the exhaust work is ensured, and it is understood that if the safety exhaust device 5 is not arranged and the furnace door 2 is directly opened, the amount of gas flowing out of the furnace body 1 is far greater than the amount of gas flowing out of the furnace body 1 after the furnace door 2 is opened for a period of time just when the furnace door 2 is opened, and the impact force of the gas is very large due to the fact that a large amount of gas is discharged in a short time just when the furnace door 2 is opened, so that the physical injury is caused to staff;
the way of gradually accelerating the opening of the oven door 2 along with the gradual decrease of the gas pressure in the oven body 1 is specifically realized is that, as shown in fig. 6, the gas inside the oven body 1 enters the inside of the movable space 5311 of the control housing 531 through the exhaust through hole 21 and the intake through hole 5312, the gas pressure inside the movable space 5311 pushes the piston 532 to move upwards against the elastic force of the second compression spring 534, the piston 532 drives the plug 533 to move inside the trumpet-shaped through hole 5313 opened in the control housing 531, as shown in fig. 7, when the plug 533 is inserted into the top of the trumpet-shaped through hole 5313, the plug 533 can be sealed with the top of the trumpet-shaped through hole 5313, since the minimum radius of the top of the trumpet-shaped through hole 5313 is larger than the radius of the section of the plug 533 by 0.04-0.08 mm, that is the gap between the minimum part of the top of the trumpet-shaped through hole 5313 and the plug 533 is 0.04-0.08 mm, the gap can realize sliding and sealing between the two, the top of the horn-shaped through hole 5313 is provided with a vertical section, the diameter of the lower side of the vertical section of the horn-shaped through hole 5313 is gradually increased, the vertical section of the horn-shaped through hole 5313 accounts for one fifth of the length of the whole horn-shaped through hole 5313, when the plug 533 is completely inserted into the inner side of the horn-shaped through hole 5313, the piston 532 moves upwards to the maximum stroke, the top of the piston 532 contacts with the top end inner wall of the control shell 531 at the moment, hydraulic oil 541 in the inner space of the control shell 54 cannot enter the inner side of the control shell 531 when the top of the piston 532 contacts with the top end inner wall of the control shell 531, the gas pressure in the furnace body 1 acts on the furnace door 2, the furnace door 2 is influenced by the gas pressure to drive the control shell 531 to move, the control housing 531 is subject to thrust forces with a tendency to move towards the inside of the control housing 54, but since the inside of the control housing 54 is provided with hydraulic oil 541, the control housing 531 at this time cannot move relative to the control housing 54, and the specific analysis is as follows, the pascal's law is a fundamental principle concerning hydrodynamics, which describes the law of pressure transmission in a closed container, according to which, when an external force acts on a gas or liquid, this force will be transmitted uniformly to each point in the liquid and an equal pressure is generated on each surface of the container, each point in the gas or liquid being subjected to the same pressure P, and if we know the area a of the piston 532 and the pressure P to which the gas or liquid is subjected, we can calculate the pressure F by the following formula:
F=P×A
The pressure F is related to the pressure P to which the gas or liquid is subjected and to the area a of the piston 532, the greater the pressure F; when the pressure is applied in the furnace body 1, the thrust force of the gas in the furnace body 1 at the position where the control shell 531 is arranged on the furnace door 2 is detected through the existing pressure instrument, the thrust force marked as F1 and F1 directly acts on the control shell 531, the thrust force of the control shell 531 applied by F1 directly acts on the hydraulic oil 541 at the inner side of the control shell 54 under the condition that the sliding friction force between the control shell 531 and the control shell 54 is not considered, the liquid pressure generated by the hydraulic oil 541 is marked as P1 at the moment, the only way the hydraulic oil 541 can flow is to push the plug 533, the cross section area of the plug 533 is marked as A1, p1=f1/A1 can be calculated according to pascal's law, where F1 can be directly detected by an instrument, and the cross-sectional area A1 of the plug 533 can also be directly measured, and finally, the thrust F1 generated by the liquid pressure on the plug 533 can be calculated; in addition, the piston 532 is directly affected by the gas pressure of the furnace 1, the gas pressure in the furnace 1 is denoted as P2, the cross-sectional area of the piston 532 is denoted as A2, and the thrust force F2 generated by the influence of the gas on the piston 532 is f2=p2×a2, so that the sizes of F1 and F2 can be controlled by controlling the cross-sectional areas of the plug 533 and the piston 532; under the condition that other small interference factors are not considered, the cross section areas of the plug 533 and the piston 532 are controlled to enable F1 to be equal to F2, on the basis that F1 is equal to F2, the elasticity of F1 plus the double-hook tension spring 61 is larger than F2 through the additional elasticity provided by the double-hook tension spring 61, as shown in figure 1, the elasticity of the double-hook tension spring 61 can act on the furnace door 2, the double-hook tension spring 61 drives the tension spring bracket 62 fixed with the shaft connecting plate 4 to move through the elasticity of the double-hook tension spring 61, the shaft connecting plate 4 is driven by the double-hook tension spring bracket 62 to drive the furnace door 2 to open, so on the basis that the double-hook tension spring 61 is installed, the furnace door 2 can be subjected to the elasticity of the double-hook tension spring 61 plus the pressure of gas in the furnace body 1, the sum of the two forces eventually acts on the hydraulic oil 541, so that the hydraulic pressure of the hydraulic oil 541 increases; before the furnace door 2 is opened, the furnace door 2 and the furnace body 1 are in a closed state, the furnace door 2 does not apply pushing force to the control shell 531, so that the oil pressure of hydraulic oil 541 is very low at the moment, when the furnace body 1 is not released and the furnace door 2 is opened, the furnace door 2 is subjected to the elastic force of the double-hook tension spring 61 to add the pressure of the gas in the furnace body 1, according to the principle, the oil pressure of the hydraulic oil 541 at the moment is relatively high, the pushing force of the hydraulic oil 541 to the plug 533 is larger than the sum of the pushing force of the gas in the furnace body 1 to the piston 532 and the pushing force of the second compression spring 534 to the piston 532, so that the piston 532 gradually moves downwards, at this time, only the spring force of the double-hook tension spring 61 is set, so that the downward movement speed of the piston 532 can be controlled, the double-hook tension springs 61 with different spring forces can be selected according to the requirement, the downward movement of the piston 532 can cause the plug 533 to move downwards together, the downward movement of the plug 533 can cause the gap between the top of the plug 533 and the trumpet-shaped through hole 5313 to be gradually increased, at this time, the hydraulic oil 541 inside the control housing 54 can flow into the inside of the control housing 531 through the gap, so that the hydraulic oil 541 inside the control housing 54 is gradually reduced, the control housing 531 can move upwards relative to the control housing 54, since the control housing 54 is fixed with respect to the oven body 1 at this time, when the control housing 531 moves upward with respect to the control housing 54, the oven door 2 is gradually opened, and as the oven door 2 is gradually opened, the gas inside the oven body 1 is discharged, so that the gas pressure inside the oven body 1 is gradually lowered, thereby causing the gas pressure inside the movable space 5311 to be gradually lowered, the partial gas pressure lowering causes the thrust force of the piston 532 by the gas pressure to be gradually reduced, the reaction force of the hydraulic oil 541 to be received is also reduced, but after the double hook tension spring 61 is installed, the double-hook tension spring 61 always provides additional elastic force regardless of the change of the gas pressure in the furnace body 1, the elastic force provided by the double-hook tension spring 61 can cause the thrust force exerted by the hydraulic oil 541 on the plug 533 to be far greater than the thrust force generated by the gas pressure in the furnace body 1 on the piston 532, the plug 533 gradually moves downwards along with the gradual downward movement of the plug 533, the gap between the top of the plug 533 and the trumpet-shaped through hole 5313 gradually increases, the larger the gap, the smaller the flow resistance of the hydraulic oil 541 when passing through the trumpet-shaped through hole 5313, the faster the hydraulic oil 541 flows into the inner side of the control housing 531, thereby realizing that the control housing 531 has an acceleration with respect to the movement of the control housing 54, and finally realizing that the opening speed of the oven door 2 is gradually increased.
It should be noted that, as mentioned above, it is necessary to control the cross-sectional areas of the plug 533 and the piston 532 so that F1 is equal to F2, that is, when other forces are not considered, such as the elasticity of the second compression spring 534 and the double-hook tension spring 61, the F1 is always equal to F2 no matter how large the gas pressure in the furnace body 1 is, it is understood that when the gas pressure inside the furnace body 1 is not greater than the normal atmospheric pressure, the piston 532 will not move, and the movement of the furnace door 2 is the thrust generated by the gas pressure inside the furnace, so that when the gas pressure inside the furnace body 1 is not greater than the normal atmospheric pressure, the furnace door 2 will not move, that is, no force acts on the control housing 531, and the control housing 531 will not squeeze the hydraulic oil 541;
It should be further noted that the gradual increase of the opening speed of the oven door 2 means that the control housing 531 gradually increases the opening speed of the oven door 2 within the moving range of the control housing 54, so that it is required to ensure that the effective stroke of the double-hook tension spring 61 matches with the gradually increasing opening speed of the oven door 2, that is, when the oven door 2 completes the gradually increasing opening speed of the oven door 2, the double-hook tension spring 61 is just shortened to the minimum length, and the spring stroke of the double-hook tension spring 61 is prevented from being too large, so that when the oven door 2 is opened subsequently, the continuous rotation of the oven door 2 collides with an operator, and when the oven door 2 is opened subsequently, one end of the double-hook tension spring 61 is removed from the tension spring bracket 62.
