Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, and more specifically to a fully automatic rapid-cooling and rapid-heating test chamber for sintered tiles. Background Art

[0002] According to the requirements of "Sintered Tiles" GB / T 21149-2019, 10 rapid-cooling and rapid-heating cycle tests are carried out on glazed tiles, which are specifically carried out in accordance with the provisions of "Test Methods for Roof Tiles" GB / T 36584-2018. The test specimens are placed on the specimen rack in an oven preheated to a temperature 150±2°C higher than the temperature of the flowing water in the water tank (preferably 15±5°C), so that the distance between the specimens and between the specimens and the oven wall is greater than or equal to 20 mm, and the oven door is closed. It is required that the oven reach the pre-set heating temperature within 5 minutes, start timing, and maintain this temperature for 45 minutes. After the heat preservation ends, immediately open the oven, take out the specimens and immerse them in the water tank filled with flowing water, and keep them for 5 minutes. The above whole process is a complete process of rapid-cooling and rapid-heating cycle.

[0003] However, it is found in the actual test process that the temperature of the specimens heated and heat-preserved in the oven is often between 158°C and 172°C, and the operator may be scalded when taking the specimens, which poses a certain safety hazard.

[0004] In summary, there are certain defects in the existing rapid-cooling and rapid-heating test chamber for sintered tiles, and it can be seen that the problems are mainly due to the relative independence of the heating link and the cooling link. Summary of the Invention

All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] The present utility model proposes to integrate a heating device and a cold water tank into an integrated test chamber, which is controlled by a temperature control system to achieve the purpose of automatic circulation. Referring to Figures 1-4 , the present utility model provides a fully automatic test chamber for the rapid cooling and rapid heating resistance of sintered tiles, including an upper water tank 1, a test chamber 2, a lower water tank 3, and an installation box 4. The test chamber 2 is fixedly installed on the bottom side of the upper water tank 1, the lower water tank 3 is fixedly installed on the bottom side of the test chamber 2, and the installation box 4 is fixedly installed on the left side of the upper water tank 1, the test chamber 2, and the lower water tank 3.

[0024] A controller 19 is fixedly installed on the front surface of the installation box 4. The controller 19 is built-in with a single-chip microcomputer, and the controller 19 is electrically connected to an external power supply through a wire.

[0025] A refrigerator 5 is fixedly installed on the left side of the upper water tank 1. The refrigeration pipe 6 of the refrigerator 5 extends into the interior of the upper water tank 1, and a delivery pipe 7 for connection is embedded between the upper water tank 1 and the test chamber 2.

[0026] A first temperature sensor 15 is fixedly installed on the inner wall of the upper water tank 1.

[0027] By setting the first temperature sensor 15, the water temperature inside the upper water tank 1 can be detected by the first temperature sensor 15.

[0028] An electromagnetic valve 17 is fixedly installed on the surface of the delivery pipe 7.

[0029] A first pump body 8 is fixedly installed on the inner wall of the installation box 4. The liquid inlet end of the first pump body 8 extends into the interior of the lower water tank 3 through a pipe, and the liquid outlet end of the first pump body 8 extends into the interior of the upper water tank 1 through a pipe.

[0030] The front surface of the test chamber 2 is of an open structure, and a sealing door 9 is hinged on the front surface of the test chamber 2. A heater 10 is fixedly installed inside the test chamber 2.

[0031] A second temperature sensor 16 is fixedly installed on the inner wall of the test chamber 2.

[0032] By setting the second temperature sensor 16, the heating temperature inside the test chamber 2 can be detected.

[0033] A liquid return pipe 11 is embedded in the lower left of the test chamber 2. The other end of the liquid return pipe 11 is connected to the liquid inlet end of the first pump body 8 and the lower water tank 3. A test bench 12 is arranged inside the test chamber 2. A plurality of jackets 13 for fixing external sintered tiles are arranged on the surface of the test bench 12 in a circumferential array. A clamping screw 14 is threadedly connected to the surface of the jacket 13.

[0034] When the utility model is in use, the sintered tile is placed inside the jacket 13 and locked with the clamping screw 14. The sealing door 9 is closed, and the water in the lower water tank 3 is pumped into the upper water tank 1 by the first pump body 8. The water is cooled by the refrigeration pipe 6 of the refrigerator 5. After the water temperature drops to the set temperature, the heater 10 is started to quickly heat the inside of the test chamber 2, so as to achieve the purpose of rapid heat treatment of the sintered tile. After the inside of the test chamber 2 is insulated for the rated time, the heater 10 is turned off, and the solenoid valve 17 on the surface of the delivery pipe 7 is opened to input cold water into the test chamber 2, so as to achieve the purpose of rapid cooling treatment of the sintered tile. During this process, the refrigerator 5 keeps working, and the water inside the test chamber 2 can continuously flow into the lower water tank 3 through the liquid return pipe 11. After the cooling is completed and the rated cooling time has passed, the second pump body 18 is automatically started to pump the accumulated water inside the test chamber 2 into the lower water tank 3 for storage, and the refrigerator 5 is turned off. Thus, a cycle of rapid cooling and heating resistance is completed. During this process, since there is no need for manual repeated handling of the test piece, the safety of the test is ensured. It should be noted that: The key step of this test is to realize a flowing water tank. When the upper water tank discharges water, the test chamber also discharges water at the same time. The premise is that the water discharge volume is much larger than the drainage volume. After the water discharge is completed, a water pump can be used to accelerate the drainage speed. Therefore, the size of the delivery pipe 7 should ensure that the water discharge volume is sufficient.

The bottom end of the vertical shaft 20 is fixedly installed with a driven bevel gear 23. The driving bevel gear 22 and the driven bevel gear 23 are meshed.

[0036] By setting the servo motor 21 and using the servo motor 21 to drive the vertical shaft 20 to rotate, the test bench 12 can be driven to rotate, so that during the rapid heating and cooling test, the position of the sintered tile can be continuously adjusted to ensure that the heat and cold effects received by each sintered tile inside the test chamber 2 are the same.

[0037] A horizontal shaft 24 is fixedly installed on the surface of the jacket 13. The jacket 13 is rotationally connected to the test bench 12 through the horizontal shaft 24. One end of the horizontal shaft 24 facing the central axis of the test bench 12 is fixedly installed with a first bevel gear 25. An extension rod 26 is fixedly installed on the inner top wall of the test chamber 2. The bottom end of the extension rod 26 is fixedly installed with a second bevel gear 27. The first bevel gear 25 and the second bevel gear 27 are meshed.

[0038] By setting the extension rod 26, and the jacket 13 is rotatably connected to the test bench 12 through the horizontal shaft 24. While the test bench 12 rotates, under the meshing action of the first bevel gear 25 and the second bevel gear 27, the jacket 13 and the sintered tile can be driven to rotate self, ensuring that the hot and cold effects on the surface of the sintered tile itself are the same, ensuring the accuracy of the test, avoiding the situation of uneven heating on the surface of the sintered tile itself, and further ensuring the accuracy of the test.

[0039] Finally, it should be noted that: in the attached drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved. For other structures, reference can be made to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other.
