The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0022] As Figures 1-4 shown, the intelligent cyclic tester for aggregate soundness of the present utility model includes a frame 1, a baking and soaking integrated box 4, a wire basket 16, a chemical pump 6, and a digital display controller 5. A liquid storage tank 2 and a water storage tank 3 are placed side by side on the frame 1; the baking and soaking integrated box 4 is located above the water storage tank 3 and the liquid storage tank 2, and the baking and soaking integrated box 4 is respectively communicated with the water storage tank 3 and the liquid storage tank 2. The wire basket 16 is slidably arranged in the baking and soaking integrated box 4; the wire basket 16 can eliminate air bubbles in the specimen during the up and down sliding process. The chemical pump 6 is located on one side of the water storage tank 3 and the liquid storage tank 2, and the chemical pump 6 is respectively communicated with the water storage tank, the liquid storage tank 2, and the baking and soaking integrated box 4 through pipelines; the chemical pump 6 can pump the clear water in the water storage tank and the anhydrous sodium sulfate solution in the liquid storage tank 2 into the baking and soaking integrated box 4; after the test, the solution and waste water in the baking and soaking integrated box 4 can respectively enter the liquid storage tank 2 and the water storage tank 3 (the water in the water storage tank for discharging waste water will not be reused and will be discharged in time after the test). The anhydrous sodium sulfate solution is used to soak the specimen, and the clear water is used to rinse the soaked test. The digital display controller 5 is located above the chemical pump 6, and the digital display controller 5 is connected to the chemical pump 6. The digital display controller 5 controls the chemical pump 6 to pump the anhydrous sodium sulfate solution or pump the clear water, and the digital display controller 5 is also used to control the lifting of the wire basket 16.
[0023] As Figure 2 shown, the baking and soaking integrated box 4 is communicated with the water storage tank 3 through a drain pipe 8, and the baking and soaking integrated box 4 is communicated with the liquid storage tank 2 through a liquid discharge pipe 7. Solenoid valves are provided on both the liquid discharge pipe 7 and the drain pipe 8, and the solenoid valves are connected to the digital display controller 5. The digital display controller 5 controls the corresponding solenoid valves on the liquid discharge pipe 7 and the drain pipe 8 to control liquid discharge or water drainage.
[0024] As Figure 2 shown, the chemical pump 6 is a corrosion-resistant chemical pump. There are two chemical pumps, namely a water pumping chemical pump and a liquid pumping chemical pump. The water pumping chemical pump is communicated with the water storage tank 3 and the baking and soaking integrated box 4 through a water suction pipe, and the liquid pumping chemical pump is communicated with the liquid storage tank 2 and the baking and soaking integrated box 4 through a circulating liquid suction pipe 9.
[0025] When it is necessary to soak the test pieces in the baking and soaking integrated box 4, the liquid extraction chemical pump pumps the anhydrous sodium sulfate solution in the liquid storage tank 2 into the baking and soaking integrated box 4 through the circulating liquid extraction pipe 9; after the soaking is completed, the anhydrous sodium sulfate solution in the baking and soaking integrated box 4 is discharged, and the water pump is used to pump the clear water in the water storage tank into the baking and soaking integrated box 4 through the water extraction pipe to wash the test pieces. After the cleaning is completed, the waste water enters the water storage tank 3 through the drain pipe and is directly discharged.
[0026] As Figures 2-4 shown, on both sides inside the baking and soaking integrated box 4, vertically arranged groove-type slide rails 15 are symmetrically installed. In the groove-type slide rails 15, a lifting rod 18 is slidably arranged. One side of the lifting rod 18 is fixedly connected to the automatic lifting frame 10 through a connecting block 17. On the side of the lifting rod 18 of the groove-type slide rail 15 on one side, away from the automatic lifting frame 10, there are a plurality of gear teeth. The lifting rod 18 is engaged with the sector turntable 19 through the gear teeth. The sector turntable 19 is connected to the edge part of the disc 20 through a connecting rod. The central axis of the disc 20 is connected to the motor, and the motor is arranged outside the baking and soaking integrated box 4. A test piece fixing frame 11 is installed between the two automatic lifting frames 10. The automatic lifting frame 10 and the test piece fixing frame 11 are fixedly connected. A plurality of wire baskets 16 are detachably suspended on the test piece fixing frame 11.
[0027] The rotation of the motor will drive the disc 20 to rotate. The rotation of the disc 20 drives the sector turntable 19 to swing up and down through the connecting rod. The up and down swing of the sector disc 19 will drive the lifting frame 18 to move up and down, thereby driving the automatic lifting frame 10 to move up and down, and further driving the wire baskets 16 on the test piece fixing frame 11 to move up and down in the anhydrous sodium sulfate solution.
[0028] The top of the wire basket 16 has a hook. The wire basket 16 is suspended on the test piece fixing frame 11 through the hook. Both the wire basket 16 and the test piece fixing frame 11 are made of corrosion-resistant stainless steel.
[0029] The test piece fixing frame 11 is of a frame structure, and the wire basket 16 can be placed in the test piece fixing frame 11.
[0030] The space of the test piece fixing frame 11 is relatively large, and multiple groups of samples of coarse and fine aggregates can be tested simultaneously.
[0031] As Figure 2 shown, a heating pipe 12 is installed at the inner bottom of the baking and soaking integrated box 4. The heating pipe 12 is connected to the digital display controller 5. The heating pipe 12 is used to heat and dry the test pieces in the baking and soaking integrated box 4. The digital display controller 5 controls the heating temperature of the heating pipe 12 at (105 ± 5) °C.
[0032] A temperature sensor 13 is installed in the baking and brewing integrated box 4. The temperature sensor 13 is a high temperature resistant sensor, and the end probe is a metal probe. The temperature sensor 13 is connected to the digital display controller 5 to transmit the real-time temperature to the digital display controller 5, thereby facilitating the digital display controller 5 to control the heater 12.
[0033] A plurality of nozzles 14 are installed on the top of the drying and foaming box 4, and the nozzles 14 are connected to a water pump, and the water pump is connected to the water storage tank 3 through a water pump, so as to spray the clean water in the water storage tank 3 through the nozzles 14 after the test is completed, and rinse the test pieces in the drying and foaming box 4.
[0034] The digital display sensor 5 is a touch screen display, and a plurality of indicator lights of different colors are installed below the touch screen display 5 to indicate different actions, such as pumping anhydrous sodium sulfate solution into the drying and foaming integrated box 4, heating the test piece, completing heating, discharging anhydrous sodium sulfate solution, pumping clean water into the drying and foaming integrated box 4 or discharging waste water.
[0035] When the utility model is used, the test personnel will load the prepared saturated sodium sulfate solution and clean water into the liquid storage tank 2 and the water storage tank 3 respectively, load the prepared test piece into the net basket 16, then place the net basket 16 on the test piece fixing frame 11, cover the box cover, turn on the power, press the start button on the digital display controller 5, and the tester starts to work. First, the anhydrous sodium sulfate solution enters the drying and immersion integrated box 4 through the circulating liquid extraction pipe 9, and the automatic lifting frame 10 descends to immerse the net basket 16 in the solution, repeatedly lifting and lowering for many times to eliminate the bubbles in the test piece. Then the automatic lifting frame 10 descends, and after the test piece is soaked for 20 hours, the anhydrous sodium sulfate solution returns to the liquid storage tank 2 through the drain pipe 7, and the heating pipe 12 starts to work, so that the temperature in the drying and immersion integrated box 4 reaches 105±5℃, and is maintained for 4 hours. At this point, the first cycle is completed. After the sample is cooled to room temperature, the second cycle begins. From the second cycle, the test piece is soaked and dried for 4 hours, and a total of 5 cycles are performed. After the last cycle is completed, clean water enters the drying and foaming integrated box 4 through the pumping pipe, and the sodium sulfate solution in the test piece is cleaned through the nozzle 14. After the cleaning is completed, the remaining waste water returns to the water storage tank 3 through the drain pipe 8 and is discharged. The heating tube 12 works again until the test piece is dried, and then the power is turned off. The test piece is taken out and the next test is continued. So far, 5 automatic intelligent cycles are achieved.
