The electric heating rod 12 can be used to heat boiled water, the heat efficiency is high, the heating and cooling speed is fast, the control is convenient, the temperature control is timely and the use is safe. The electric heating rod 12 is heated by the heat generated when the current passes through the resistance. The heat transfer method is heat conduction, that is, the heat freely diffuses from the high-temperature object to the low-temperature object. The heating method is simple and has strong applicability. The test process of cement stability is as follows: 1) Make the test piece by the test cake method or the Rayleigh method, put the test piece in the curing box and cure it for 24±2h. 2) Fill the boiling box with water, and put the cured test piece on the box grate. 3) Turn on the power supply of the controller, use the electric heating rod 12 to boil the water in the boiling box, and conduct the test; after boiling, pump the water out, open the box cover 11 and wait for the box to cool to room temperature, and take out the test piece for identification. Cake test method: Judgment method after the test cake is boiled: When no cracks are found in the visual test cake and no bending is measured with a steel ruler, the stability of the corresponding cement is considered to be qualified. In order to improve heating efficiency, the box body 1 includes an outer shell 14 and an inner tank 15, both of which are rectangular. The inner tank 15 is made of copper, the outer shell 14 is made of stainless steel, the electric heating rod 12 passes through the outer shell 14 and the inner tank 15 into the box body 1 in turn, and the electric heating rod 12 is connected to the outer shell 14 by flange. The shell 14 is provided with a thermal insulation cavity 8 around the outer surface of the liner 15, and the thermal insulation cavity 8 is provided with an asbestos net 9. After the electric heating rod 12 is heated, the heat passes through the blocking effect of the asbestos net 9, so that the heat is better retained in the box. 1, so that the heating efficiency is higher.

Referring to Figure 1 and Figure 2, after the boiling tank is used for a long time, scale will accumulate in the tank 1, which will affect the heating effect of the electric heating rod 12 and reduce the heating efficiency, so the front, rear and left inner walls of the tank 1 All are connected with filter screen 6 on the top. The filter screen 6 is made of gauze material, which can effectively absorb scale and keep the test water in the boiling tank clean, so as to draw more accurate test conclusions. And the presence of the filter screen 6 also reduces the formation of scale on the inner wall of the box body 1 and the electric heating rod 12, which facilitates the cleaning of the equipment after long-term use. A fixing post 7 for fixing the filter screen 6 is threaded on the inner side wall of the box body 1 , and a threaded hole 71 is provided on the inner side wall of the box body 1 , and the fixing post 7 is threadedly connected to the threaded hole 71 . The filter screen 6 is connected with a lanyard 61 cooperating with the fixed column 7, and the cooperation of the fixed column 7 with the lanyard 61 facilitates disassembly and replacement of a new filter screen 6. In this embodiment, there are totally four fixing columns 7 located at the four corners of the rectangular filter screen 6 respectively.

Referring to Fig. 1 and Fig. 2, an L-shaped mounting frame 2 is connected to the outer wall of the casing 1, and a descaling device is connected to the top of the mounting frame 2, and the descaling device includes a brush 3 extending into the casing 1 to clean dirt. , the first driving device for driving the brush 3 to move in the horizontal direction and the second driving device for driving the brush 3 to move in the vertical direction, which are screwed on the mounting frame 2 . In this embodiment, the first driving device is the first hydraulic rod 4 screwed on the top side of the installation frame 2 , and the driving end of the first hydraulic rod 4 is connected with a support plate 41 .
