Description

Technical Field

[0001] The present invention relates to the technical field of refractory material tests, and particularly relates to an anti-burst experiment device for castables used in waste incineration and an experimental method thereof. Background Art

[0002] Castable is a granular and powdery material made of refractory substances, and is composed of a certain amount of binder and moisture. It has high fluidity, is suitable for construction by casting method, and is an amorphous refractory material that can harden without heating. It is composed of refractory aggregates, powders, binders, admixtures, water or other liquid materials. Generally, it is cast and formed at the use site by casting, vibrating or ramming methods, and can also be made into prefabricated parts for use.

[0003] Castables are generally used in the manufacture of waste incinerators in waste incineration. The reasons for the bursting of waste incinerators are as follows: First, the burning temperature is too high, and the internal crystal water of the castable evaporates, resulting in the bursting of the furnace body; second, an explosion occurs inside the waste incinerator, the gas expands, and the internal air pressure of the waste incinerator rises instantaneously, resulting in the bursting of the waste incinerator.

[0004] In the prior art, generally, a refractory high-temperature experiment is carried out on the castable to detect the anti-burst performance of the castable against high temperatures; after the castable is made into a waste incinerator, a high-pressure resistance experiment is carried out to set the peak air pressure that the waste incinerator can withstand; however, there are great problems with this experimental method. First, after the castable is made into a large waste incinerator, the internal space of the waste incinerator is large, and it is impossible to input a controllable amount of gas in a short time by the device, making it difficult to limit; second, the power of the pressurization equipment used in the experiment is very large. When approaching the internal air pressure of the castable, it is difficult to adjust and gradually slow down the air pressure input by the pressurization equipment into the castable, and the obtained experimental data is inaccurate; third, when conducting a gas pressure experiment, it is difficult to seal between the castable mold and the experimental equipment, and gas leakage will cause deviations in the experimental data.

[0014] An experimental method for an anti-explosion experiment device of a castable for garbage incineration includes the following experimental steps:

[0015] The first step: Before the experiment starts, the experimenter opens the experimental cabin through the cabin door and puts the casting cavity model into the experimental cabin.

[0016] The second step: Subsequently, the limiting mechanism operates to clamp the top edge of the casting cavity model, and the casting cavity model can be fixed.

[0017] The third step: The pressing mechanism starts to press down to the opening of the casting cavity model to close the opening of the casting cavity model. After the experimenter closes the opening of the casting cavity model by the engagement of the pressing mechanism and the limiting mechanism, the experimenter exits the experimental cabin and closes the cabin door tightly.

[0018] The fourth step: The heating rod conducts a refractory high-temperature experiment on the casting cavity model. If the experiment passes, continue to detect the peak value of the air pressure that the casting cavity model can withstand. If the experiment fails, stop the experiment, and the anti-explosion performance of this castable is unqualified.

[0019] The fifth step: If the experiment passes, remove the heating rod, and then the pressurizing mechanism starts to operate. Gas is injected into the casting cavity model through the pipeline to increase the air pressure inside the casting cavity model, so that the air pressure inside the casting cavity model gradually approaches the peak value.

[0020] The sixth step: As the air pressure inside the casting cavity model increases, the adjusting mechanism starts to adjust the channel area of the gas supply from the pressurizing mechanism to the casting cavity model to reduce the increasing rate of the air pressure inside the casting cavity model.

[0021] Step 7: When the casting cavity model bursts, the experimenter records the experimental data of the bursting moment, then conducts multiple comparative experiments, records the data, and then calculates the peak value of the air pressure that the casting cavity model can withstand, and compares it with the domestic standard to see whether the casting material meets the standard. If it meets the standard, the maximum air pressure that can be borne is marked on the casting material.

[0022] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0023] First, the limiting mechanism operates to clamp the top edge of the pouring cavity model, which can fix the pouring cavity model for convenience of experiment. Then the pressing mechanism starts to press down to the opening of the pouring cavity model to close the opening of the pouring cavity model. After the experimenter seals the opening of the pouring cavity model by engaging the pressing mechanism with the limiting mechanism, he exits the experimental cabin, closes the cabin door, and uses the heating rod to perform a fire-resistant high-temperature test on the pouring cavity model. If the experiment passes, the boosting mechanism starts to operate to inject gas into the pouring cavity model through the pipeline to increase the air pressure in the pouring cavity model and detect the peak value of the air pressure that the pouring cavity model can withstand. As the air pressure inside the pouring cavity model increases, the regulating mechanism starts to adjust the channel area of ​​the boosting mechanism to supply air to the pouring cavity model to reduce the rate of increase of the air pressure inside the pouring cavity model. When the pouring cavity model bursts, the amount of change inside the pouring cavity model per unit time is small, and the data recorded by the experimenter is relatively accurate. Subsequently, multiple comparative experiments are carried out to record the data, and then the peak value of the air pressure that the pouring cavity model can withstand is calculated.

[0024] Secondly, the pressing mechanism is driven by the pressing motor to drive the threaded rod to rotate, driving the sealing cover to move down to the opening of the casting cavity model. When the sealing cover descends, the experimenter must rotate the rotating ring to align the clamping block with the closed groove of the semi-confined ring. After the sealing cover reaches the specified position, the experimenter rotates the rotating ring to clamp the sealing cover on the casting cavity model and the semi-confined ring, and uses the rotating ring to seal the sealing cover and the semi-confined ring to prevent gas leakage during the experiment and cause deviations in the experimental data.

[0025] Thirdly, the boost mechanism is operated by a boost motor, which drives the eccentric wheel to rotate, thereby driving the boost clamp eccentrically arranged on the eccentric wheel to move, so that the boost clamp drives the boost pressure plate to move in the boost cylinder through the boost connecting plate, and the gas inside the boost cylinder is input into the casting cavity model through the pipeline and the air inlet. The boost cylinder is provided with a scale, and the amount of gas input into the casting cavity model can be visualized, which is convenient for the experimenter to record data. At the same time, the amount of gas input into the casting cavity model can be controlled by the rotation of the boost motor. When the boost pressure plate contracts upward, the airtight flap at the air outlet end of the boost cylinder is closed, and the airtight flap on the boost pressure plate is opened. When the boost pressure plate is pressed downward, the airtight flap at the air outlet end of the boost cylinder is opened, and the airtight flap on the boost pressure plate is closed, so as to infuse gas into the boost cylinder.

[0026] Fourthly, the regulating mechanism uses the internal air pressure of the pouring cavity model as a power source. The internal air pressure of the pouring cavity model will squeeze the regulating pressure plate, and the regulating pressure plate will resist the regulating telescopic rod and the regulating spring to retract. Then the regulating pressure plate will drive the regulating plate to move on the slide rail through the adjusting connecting rod. The greater the internal air pressure of the pouring cavity model, the greater the retraction distance of the regulating pressure plate, the greater the distance the pushed regulating plate moves, and the larger the area of ​​the air inlet closed by the two regulating plates. Until the two regulating plates are closed, the gas input from the boosting mechanism enters the pouring cavity model only through two semi-lunar through holes, the injected gas path becomes smaller, and when the pouring cavity model bursts, a closer peak value of the pouring cavity model burst can be obtained.

[0027] Fifth, after an experiment is completed, multiple comparative experiments are required according to the rigor of the experiment. The position of the plug plate can be adjusted by the pin. When the position of the plug plate changes, the angle between the boost clamp and the boost connecting plate will change. The total amount of input inside the boost cylinder will change each time, and each socket corresponds to a different total amount of gas inside the boost cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] An experimental method for an anti-burst experiment device of a casting material for waste incineration includes the following experimental steps:

[0053] The first step: Before the experiment starts, the experimenter opens the experimental chamber 1 through the hatch 12 and puts the casting cavity model into the experimental chamber 1.

[0054] The second step: Subsequently, the limiting mechanism 2 operates to clamp the top edge of the casting cavity model, and the casting cavity model can be fixed.

[0055] The third step: The pressing mechanism 3 starts to press down to the opening of the casting cavity model to close the opening of the casting cavity model.

[0057] Step 5: If the experiment passes, the heating rod 11 is removed, and then the booster mechanism 4 starts to operate, injecting gas into the casting cavity model through the pipeline 13 to increase the air pressure in the casting cavity model, so that the air pressure inside the casting cavity model gradually approaches the peak value;

[0058] Step 6: As the air pressure inside the casting cavity model increases, the regulating mechanism 5 begins to adjust the channel area through which the boosting mechanism 4 supplies air to the casting cavity model, so as to reduce the rate of increase of the air pressure inside the casting cavity model;

[0059] Step 7: When the casting cavity model bursts, the experimenter records the experimental data of the bursting moment, then conducts multiple comparative experiments, records the data, and then calculates the peak value of the air pressure that the casting cavity model can withstand, and compares it with the domestic standard to see whether the casting material meets the standard. If it meets the standard, the maximum air pressure that can be borne is marked on the casting material.

An air outlet (36) and an air inlet (37) are provided on the sealing cover (32). The pressing mechanism (3) is driven by the pressing motor (34) to rotate the threaded rod (35), driving the sealing cover (32) to move downward to the opening of the casting cavity model. When the sealing cover (32) moves downward, the experimenter needs to rotate the rotating ring (33) to align the clamping blocks (38) with the sealing grooves of the semi-limiting ring (25). Subsequently, after the sealing cover (32) reaches the specified position, the experimenter rotates the rotating ring (33) to clamp the sealing cover (32) on the casting cavity model and the semi-limiting ring (25), and uses the rotating ring (33) to seal the space between the sealing cover (32) and the semi-limiting ring (25).

The two adjusting pressing plates (56) are respectively slidably installed in the two adjusting cylinders (53).

Semi-circular through holes are provided on both of the two adjusting plates (58). The adjusting mechanism (5) uses the internal air pressure of the pouring cavity model as the power source. The internal air pressure of the pouring cavity model will squeeze the adjusting pressing plate (56). The adjusting pressing plate (56) will resist the adjusting telescopic rod (55) and the adjusting spring (54) to retract. Then the adjusting pressing plate (56) will drive the adjusting plate (58) to move on the slide rail (52) through the adjusting connecting rod (57). The greater the internal air pressure of the pouring cavity model, the greater the retraction distance of the adjusting pressing plate (56), and the greater the moving distance of the position of the driven adjusting plate (58). The area of the air inlet (37) closed by the two adjusting plates (58) is larger until the two adjusting plates (58) are closed. The gas input from the pressurizing mechanism (4) only enters the pouring cavity model through the two semi-circular through holes, and the injection gas path becomes smaller. When the pouring cavity model bursts, a peak closer to the burst of the pouring cavity model can be obtained. A gas treatment box (81) is provided at the top of the experimental chamber (1). The air outlet (36) on the sealing cover (32) is communicated with the inside of the gas treatment box (81) through a pipeline (13). A remote switch (82) is provided on the pipeline (13) between the air outlet (36) on the sealing cover (32) and the gas treatment box (81). It includes the following steps: The first step: Before the experiment starts, the experimenter opens the experimental chamber (1) through the hatch (12) and puts the pouring cavity model into the experimental chamber (1). The second step: Subsequently, the limiting mechanism (2) operates to clamp the top edge of the pouring cavity model, and the pouring cavity model can be fixed. The third step: The pressing mechanism (3) starts to press down to the opening of the pouring cavity model to close the opening of the pouring cavity model. After the experimenter closes the opening of the pouring cavity model by fitting the pressing mechanism (3) with the limiting mechanism (2), the experimenter exits the experimental chamber (1) and closes the hatch (12). Step 4: The heating rod (11) conducts a refractory high-temperature experiment on the casting cavity model. If the experiment passes, continue to detect the peak air pressure that the casting cavity model can withstand. If the experiment fails, stop the experiment, and the anti-burst performance of this castable is unqualified. Step 5: If the experiment passes, remove the heating rod (11). Subsequently, the pressurizing mechanism (4) starts to operate, and gas is injected into the casting cavity model through the pipeline (13) to increase the air pressure inside the casting cavity model, making the air pressure inside the casting cavity model gradually approach the peak value. Step 6: As the air pressure inside the casting cavity model increases, the adjusting mechanism (5) starts to adjust the channel area through which the pressurizing mechanism (4) delivers gas to the casting cavity model to reduce the increasing rate of the air pressure inside the casting cavity model. Step 7: When the casting cavity model bursts, the experimental personnel record the experimental data at the moment of bursting. Subsequently, conduct multiple comparative experiments, record the data, and then deduce the peak air pressure that the casting cavity model can withstand. Compare it with the domestic standard to check whether this castable meets the standard. If it meets the standard, mark the maximum withstand air pressure for this castable.
