Incineration has become an important way of harmless treatment of domestic waste. It can effectively reduce the volume of garbage, reduce hazards and generate energy. Slag, as a product of the incineration of domestic waste, has become an important indicator for the supervision and evaluation of domestic waste incineration plants. In the current era where operation is king, it is an important part of domestic waste incineration plants to improve their refined management level.

[0071] The paving drive screw 802 is rotatably connected to the inside of the processing body 1, and the paving drive screw 802 is coaxially fixedly connected to the right end of the rotating shaft of the paving drive motor 801. The left and right sides of the paving drive screw 802 are both reciprocating screw structures.

[0072] The paving guide rod 803 is fixedly connected to the inside of the processing body 1. The paving guide rod 803 is arranged below the paving driving screw 802. The paving guide rod 803 provides a guiding support function for the paving member 804 to ensure the stability of the paving member 804 when moving;

[0073] There are two groups of paving parts 804, which are respectively threadedly connected to the left and right sides of the paving drive screw 802. The two groups of paving parts 804 are slidably connected to the paving guide rod 803. The lower ends of the two groups of paving parts 804 are provided with multiple groups of long rod structures. During use, the paving drive motor 801 is turned on, and the rotation of the rotating shaft of the paving drive motor 801 drives the paving drive screw 802 to rotate.

[0076] The sampling plate 807 is slidably connected to the lower end of the outer side of the sampling guide rod 806, and the sampling plate 807 is threadedly connected to the sampling drive screw 805. The sampling plate 807 realizes the scraping of the slag, and evenly scrapes the slag into the interior of the sampling box body 8;

[0078] The sampling guide plate 809 is fixedly connected to the left side of the processing body 1, and the sampling guide plate 809 realizes the guiding function of the slag sample;

[0079] The sampling box cover 810 is slidably connected to the upper end of the sampling box body 8.

[0080] The sampling return spring 811 is fixedly connected to the right end of the sampling box body 8, and the right end of the sampling return spring 811 is fixedly connected to the sampling box cover 810;

[0081] The sampling weighing piece 812 is a pressure sensor structure, and the sampling weighing piece 812 is fixedly connected to the lower end of the sampling support frame 7. When the dynamic pressure of the slag to be measured acts on the elastic sensitive element of the sampling weighing piece 812, it is deformed. Resistance strain gauges are attached to the deformed parts. These strain gauges sense the change of pressure and then convert the change into an electrical signal.

[0082] The sampling reminder speaker 813 is fixedly connected to the left side of the sampling support frame 7 , and the control circuit of the sampling weighing member 812 is electrically connected to the control circuit of the sampling reminder speaker 813 .

[0083] During use, the spreading drive motor 801 is turned on, and the rotation of the shaft of the spreading drive motor 801 drives the spreading drive screw 802 to rotate, and the rotation of the spreading drive screw 802 drives the spreading member 804 to move back and forth left and right.

Inside the sample box 8, the sampling box 8 realizes the collection of slag samples. At the same time, when the sampling top rod 808 moves to the right, the sampling box cover 810 is reset under the action of the sampling reset spring 811, and the sampling box cover 810 realizes the shielding of the slag sample inside the sampling box 8, avoiding the contamination of the slag sample by external debris, and ensuring the accuracy of the test results. When the slag sample is collected to the set threshold, the dynamic pressure of the slag under test acts on the elastic sensitive element of the sampling weighing piece 812, causing it to deform. Resistance strain gauges are pasted on the deformed parts, and these strain gauges sense the change in pressure and then convert this change into an electrical signal. The electrical signal emitted by the sampling weighing piece 812 passes through the control circuit of the sampling prompt speaker 813.

Sampling: directly take out the slag or residue from the sampling box as the test sample; S2. Prepare bulk samples: Grind and sieve the samples using a grinder and a laboratory sieve to remove large impurities; S3. Drying: Place the treated sample in an electric drying oven and dry it to constant weight at 110°C ± 5°C; S4. Prepare a small sample: weigh 1 gram of the dried sample as a small sample and put it into a porcelain crucible; S5.
