Abstract
Description
Technical Field
[0001] This application relates to the field of cementing material production technology, specifically to a cementing material high-temperature adaptability testing device. Background Technology
[0002] In existing technologies, when testing the high-temperature adaptability of cementing materials, a high-temperature airflow is typically used to heat the cementing material test block, followed by pressurization using pressure devices to observe the degree of breakage and the pressure during breakage. Some testing equipment requires removing the entire test block and placing it under a hydraulic press for testing, which causes a sudden drop in temperature during transport, affecting the test results. Some testing equipment uses a hydraulic press to squeeze the test block directly inside a heated container without transferring it. Due to the high temperature inside the heated container, the broken test block cannot be easily removed, and some residue remains inside the heated container, making it difficult to quickly complete the subsequent testing of the test block. Utility Model Content
[0003] In view of the above problems, this application provides a high-temperature adaptability testing device for cementing materials, which can facilitate the quick and convenient removal of cementing material fragments from the heating container.
[0004] According to one aspect of the embodiments of this application, a high-temperature adaptability testing device for cementing materials is provided. The cementing material high-temperature adaptability testing equipment includes a base, a circulating heating device on one side of the base, and multiple temperature control boxes arranged sequentially in a straight line above the base. Each temperature control box contains an air outlet device. The circulating heating device is connected to an air supply pipe and a return pipe. The air supply pipe is connected to multiple air outlet devices via multiple first valve bodies and pipes. Each of the multiple temperature control boxes is connected to the return pipe via second valve bodies and pipes. A support frame is provided on one side of each temperature control box, and a sliding hydraulic actuator, including a hydraulic cylinder, is connected to the support frame via a rail. A purging air gun is provided on one side of the support frame, and the purging air gun is connected to an air pump via a pipe. The bottom of the temperature control box is divided into a first stepped surface and a second stepped surface, with the first stepped surface higher than the second stepped surface. The first and second stepped surfaces are connected by a gentle slope. A support platform is provided at the top of the first stepped surface. A receiving groove is formed on the side of the second stepped surface near the side wall of the temperature control box, and a dust bag is placed in the receiving groove.
[0005] In some embodiments, the temperature control box includes a box body and a cover plate. The top of the box body has two slots, and the bottom sides of the cover plate have tracks corresponding to the slots. A sealing strip is provided below the tracks.
[0006] In some embodiments, the gray bag includes a storage compartment at the bottom, the top of the storage compartment expanding outwards to form an open shape, and a limiting plate with a C-shaped cross-section connected to the top of the storage compartment.
[0007] In some embodiments, a handle component is provided on one side of the limiting plate, and the handle component is made of heat-insulating material.
[0008] In some embodiments, each temperature control box is provided with a temperature detection component, and a display is provided on the outside of each temperature control box. The display is electrically connected to the temperature detection component and is used to display the reading of the temperature detection component.
[0009] In some embodiments, the display is a PLC control box with a display screen, the first valve body and the second valve body are both solenoid valves, and the PLC control box is electrically connected to the solenoid valves.
[0010] The beneficial effects of this application are as follows: By setting up an air supply pipe and a return pipe, as well as multiple independent temperature control boxes, multiple cementing material test blocks can be tested for high temperature adaptability simultaneously during the experiment. Furthermore, by controlling the opening amplitude of the first and second valve bodies, the flow rate of the high-temperature gas flow can be controlled, thereby allowing for individual temperature control in each temperature control box, making operation more convenient.

[0021] For details, please refer to Figure 1 and Figure 5 , Figure 1 This is a schematic diagram of the overall structure of the device provided in an embodiment of this application. Figure 2 A structural schematic diagram of the temperature control box and circulating heating equipment is provided for the embodiments of this application. Figure 3 This is a partial structural diagram of the temperature control box provided in an embodiment of this application. Figure 4 This is a partial structural diagram of the gray bag provided in an embodiment of this application. Figure 5This is a partial structural diagram of the cover plate provided in an embodiment of this application. The cementing material high-temperature adaptability testing equipment 100 includes a base 110, which should have sufficient stability and can therefore be fixed on a stable structure such as a stone platform. A circulating heating device 120 is provided on one side of the base 110. The circulating heating device 120 can be commercially available. The circulating heating device 120 is used to heat the air and deliver it to each temperature control box 130, and to recirculate and heat the airflow discharged from the temperature control box 130. Multiple temperature control boxes 130 are arranged sequentially in a straight line above the base 110. Each temperature control box 130 is independent of each other, and its internal temperature can be the same or different depending on the actual use. An air outlet device 131 is provided inside the temperature control box 130 to evenly distribute the hot air inside the temperature control box 130. The circulating heating device 120 is connected to a gas supply pipe 121 and a return pipe 122. The gas supply pipe 121 is connected to multiple gas outlet devices 131 through multiple first valve bodies 123 and pipes. The hot air in the circulating heating device 120 is transported to the gas outlet devices 131 through the gas supply pipe 121, the first valve bodies 123 and pipes, and then flows evenly out of the gas outlet devices 131 into the temperature control box 130. The multiple temperature control boxes 130 are connected to the return pipe 122 through second valve bodies 124 and pipes. The airflow inside the temperature control box 130 enters the return pipe 122 through the second valve bodies 124 and pipes, and then enters the circulating heating device 120 for reheating. A support frame 140 is provided on one side of the temperature control box 130. A sliding hydraulic device, including a hydraulic cylinder 141, is connected to the support frame 140 via a rail. The sliding hydraulic device can be configured with reference to existing technology. It is used to move above each temperature control box 130 and to perform a compression test on the cementing material test blocks inside. A purge air gun 142 is provided on one side of the support frame 140. The purge air gun 142 is connected to an air pump via a pipe. The purge air gun 142 blows out the hot air inside the temperature control box 130 by spraying high-pressure airflow, which can then purge the temperature control box 130, so that the cementing material test blocks inside the temperature control box 130 are blown into the dust bag 150. The bottom of the temperature control box 130 is divided into a first step surface 132 and a second step surface 133. The first step surface 132 is higher than the second step surface 133. The first step surface 132 and the second step surface 133 are connected to each other by a gentle slope. A support platform 132a is provided on the top of the first step surface 132. The cementing material test block will be placed on the support platform 132a. To ensure stability, the bottom of the support platform 132a should not be hollow.A receiving groove 133a is provided on the side of the second step surface 133 near the side wall of the temperature control box 130. A dust bag 150 is placed in the receiving groove 133a. When the high temperature condition is met, the temperature control box 130 can be opened and the dust bag 150 can be placed into the receiving groove 133a (at this time, the dust bag 150 does not contact the bottom wall of the receiving groove 133a). At this time, the purge air gun 142 is turned on to purge the fragments inside the temperature control box 130 into the receiving groove 133a. The fragments will enter the dust bag 150 in the receiving groove 133a. When there are no fragments on the first step surface 132 and the second step surface 133, the dust bag 150 is controlled to move downward and the purge air gun 142 is used to purge again until the bottom of the dust bag 150 contacts the bottom wall of the receiving groove 133a or the fragments on the top end face of the dust bag 150 fall completely into the dust bag 150.
[0022] As can be seen from the above, in this embodiment, by setting up an air supply pipe 121 and a return pipe 122, as well as multiple independent temperature control boxes 130, multiple cementing material test blocks can be tested for high temperature adaptability simultaneously during the experiment. Furthermore, by controlling the opening amplitude of the first valve body 123 and the second valve body 124, the flow rate of the high-temperature airflow can be controlled, thereby allowing for individual temperature control in each temperature control box 130, making operation more convenient. On the other hand, in this embodiment, by setting up a first step surface 132 and a second step surface 133, the bottom of the temperature control box 130 is divided into two parts. By setting up a receiving groove 133a, a dust bag 150, and a purging air gun 142, components such as a hopper 133a, work together to purge fragments inside the temperature control box 130 into the dust bag 150 for easy removal. During the purging process, the dust bag 150 gradually descends, allowing for multi-stage purging, ensuring that fragments on the contact surface between the dust bag 150 and the receiving groove 133a are completely blown into the dust bag 150.
[0023] In some embodiments, the temperature control box 130 includes a box body and a cover plate 134. Two slots are provided on the top of the box body, and tracks corresponding to the slots are formed on both sides of the bottom of the cover plate 134. A sealing strip is provided below the tracks. In this embodiment, with the above configuration, when the cover plate 134 is inserted into the box body through the tracks, the temperature control box 130 will be in a semi-closed state, and the sealing strip further improves its sealing performance, facilitating the maintenance of the internal temperature of the temperature control box 130.
[0024] In some embodiments, the ash hopper 150 includes a storage hopper 151 located at the bottom. The top of the storage hopper 151 expands outward to form an open shape, and a limiting plate 152 with a C-shaped cross-section is connected to the top of the storage hopper 151. In this embodiment, the above-described arrangement can effectively prevent fragments from falling onto the top surface of the ash hopper 150 during the blowing process without falling into the ash hopper 150.
[0025] In some embodiments, a handle component 153 is provided on one side of the limiting plate 152, and the handle component 153 is made of heat-insulating material. In this embodiment, by providing the handle component 153, it is convenient for the operator to hold the ash bag 150.
[0026] In some embodiments, each temperature control box 130 is equipped with a temperature detection component, and a display is provided on the outside of each temperature control box 130. The display is electrically connected to the temperature detection component and is used to display the reading of the temperature detection component. In this embodiment, the above-mentioned arrangement allows operators to monitor the internal temperature of the temperature control box 130 in real time and flexibly adjust the internal temperature of the temperature control box 130 according to the reading.
[0027] In some embodiments, the display is a PLC control box 160 with a display screen, and both the first valve body 123 and the second valve body 124 are solenoid valves. The PLC control box 160 is electrically connected to the solenoid valves. In this embodiment, through the above settings, the PLC control box 160 adjusts the opening and closing of the solenoid valves and the opening and closing range according to the temperature measured by the temperature detection component, thereby realizing automated temperature control, reducing labor costs, and avoiding human error and operational risks.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
