A top cover 53 is slidably connected to the two guide shafts 511. A sealing element is provided at the connection between the top cover 53 and the cleaning tank 52. The sealing element at the connection between the top cover 53 and the cleaning tank 52 is a rubber ring. Two lifting cylinders 54 are installed at the bottom of the fixed frame 51. The movable ends of the two lifting cylinders 54 pass through the fixed frame 51 and are connected to the upper cover 53. A cleaning rack 55 is connected to the inner wall of the cleaning tank 52. Spray nozzles 57 are installed at the bottom of the cleaning tank 52 and on the side wall of the upper cover 53.

An air jet pipe 58 is provided at the top of the upper cover 53. The air jet pipe 58 is connected to a heat source through pipes.
[0032] In this embodiment, the storage mechanism 6 includes a placement rack 61, which is installed on the table surface of the testing station 1. Multiple first trays 62 are connected to the placement rack 61 for storing material cups 7 and multiple second trays 63 for storing beakers 8. The first trays 62 and the second trays 63 can move up and down and rotate left and right along the placement rack 61, and their number can be increased or decreased according to actual needs.
[0033] The working process and principle of this invention are as follows: In use, when the cup 7 containing clinker powder is placed onto the lifting block 24 through the feed inlet 13, the lifting cylinder 23 is activated, pushing the lifting block 24 upward to lift the cup 7 onto the surface of the testing platform 1. At this time, the robotic arm 11 and gripper 12 grab the cup 7 at the opening of the lifting cylinder 21 and pour it into the funnel 35 of the weighing mechanism 3. The clinker powder enters the vibrating feeder 36 from the funnel 35. The robotic arm 11 and gripper 12 place the empty cup 7 on the first tray 62, and then grab the beaker 8 and place it in the cup holder 33. The vibrating feeder... The vibrating feeder 36 starts working, slowly vibrating the clinker powder through the feed nozzle 361 into the beaker 8 below. The powder in the beaker 8 is weighed by the balance 32. When the powder mass reaches 0.5g, the vibrating feeder 36 stops working, the powder feeding stops, the robotic arm 11 and gripper 12 grab the beaker 8 and move it to the titration mechanism 4. Then the cleaning cylinder 38 opens and retracts, driving the waste nozzle of the waste box 39 to align with the feed nozzle 361. The dust collector is opened to suck away the residual powder in the vibrating feeder. Then the dust collector is closed, and the cleaning cylinder 38 extends and returns to its original position.
[0034] After weighing, the clinker powder and beaker 8 are placed in the positioning ring 45 on the heating plate 44. The robotic arm 11 and gripper 12 grab another beaker 8 (prepared in advance) containing ethylene glycol solution from the storage mechanism 6 and add the ethylene glycol solution to beaker 8 on the heating plate 44. Then, the linear module 42 drives the support 43 to move downward to beaker 8. At the same time, the stirrer 46 and the heating plate 44 are turned on to stir and heat the mixed solution in beaker 8. After stirring and heating for a period of time, the stirring and heating are stopped. The titrator titrates the fully reacted mixed solution through the titration tube 48 on the support 43. The potentiometric pH meter measures the pH value of the mixed solution in real time. The titration endpoint is determined by the algorithm, and the titration process ends automatically, thereby calculating the content of free calcium in the clinker. After the titration is completed, the support 43 rises to the initial position, and the robotic arm 11 and gripper 12 transfer beaker 8 to the cleaning mechanism 5.
[0035] The robotic arm 11 and gripper 12 hold the beaker 8 and move it above the cleaning tank 52 in the cleaning mechanism 5 (at this time, the cleaning tank 52 and the top cover 53 are in the open state). The reacted solution is poured into the cleaning tank 52. Then, the beaker 8 is placed upside down on the cleaning rack 55. After the through-beaker sensor 56 detects that the beaker is in place, the top cover 53 is closed and locked with the cleaning tank 52 under the drive of the lifting cylinder 54. The booster water pump is turned on and the beaker 8 is rinsed through multiple nozzles 57. After rinsing, the hot air source is turned on and the beaker 8 is dried by blowing through the jet pipe 58. After drying, the top cover 53 is raised, and the robotic arm 11 and gripper 12 grab the beaker 8 and move it to the second tray 63 for storage.
[0036] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
