The first temperature detection sensor, the second temperature detection sensor, the liquid level detection sensor, the first electrically-controlled on-off valve and the second electrically-controlled on-off valve are electrically connected to the control device.

When the second electrically-controlled on-off valve is opened, the second pipeline 600 is arranged to supply the second water body into the preparation tank 400. The preparation tank 400 is used for preparing the mixed water, and the use tank 300 is used for containing the mixed water. When the use tank 300 lacks the mixed water, the preparation tank 400 supplies the mixed water into the use tank 300.

[0039] As shown in Figure 1 and Figure 2 The embodiment of the present application provides a preparation method of mixed water, which comprises the following steps.

[0040] Obtaining the temperature T1 of the gypsum in the stock bin 100 and the mixing ratio K of the mixed water and the gypsum;

[0041] According to T1 and K, determining the temperature T2 of the mixed water to be prepared;

[0042] Supplying the first water body with the temperature T3 and the second water body with the temperature T4 into the preparation tank 400 to prepare the mixed water, and maintaining the temperature of the mixed water prepared in the preparation tank 400 at T2;

[0043] Wherein, T3>T2>T4. The mixing ratio K of the mixed water and the gypsum determines the type of the gypsum board to be prepared, and the temperature of the gypsum in the stock bin 100 can be maintained in a set range when the gypsum reaches the mixer 200.

[0044] The preparation method of the mixed water, according to the temperature T1 of the gypsum in the stock bin 100 and the mixing ratio K of the mixed water and the gypsum, determines the temperature T2 of the mixed water to be prepared, and then prepares the mixed water with the temperature T2 in the preparation tank 400. In this way, the first set amount M of the mixed water and the second set amount M / K of the gypsum can guarantee that the temperature of the gypsum slurry prepared after being stirred in the mixer 200 is exactly the temperature of the gypsum slurry required for preparing the corresponding type of gypsum board, without the need to heat or cool the gypsum slurry. This scheme is more simple and reasonable in controlling the temperature of the gypsum slurry. The mixing ratio K of the mixed water and the gypsum can be fed back to the control device by the upper computer.

[0045] In some examples, asFigure 1 and Figure 3 As shown in FIG. 1, the step of supplying the first water body with temperature T3 and the second water body with temperature T4 into the preparation tank 400 and maintaining the temperature of the blended water prepared in the preparation tank 400 at T2 includes:

[0046] Supplying the first water body with temperature T3 into the preparation tank 400;

[0047] Obtaining the temperature T5 of the liquid in the preparation tank 400 and the liquid level of the liquid in the preparation tank 400;

[0048] Based on T5-T2≥T6≥0 and the liquid level of the liquid in the preparation tank 400 not reaching the set liquid level, supplying the second water body with temperature T4 into the preparation tank 400, and then performing the step of obtaining the temperature T5 of the liquid in the preparation tank 400 and the liquid level of the liquid in the preparation tank 400;

[0049] Based on T5-T2≤T7≤0 and the liquid level of the liquid in the preparation tank 400 not reaching the set liquid level, stopping supplying the second water body into the preparation tank 400, and then performing the step of obtaining the temperature T5 of the liquid in the preparation tank 400 and the liquid level of the liquid in the preparation tank 400;

[0050] Based on T6

[0051] Based on the liquid level of the liquid in the preparation tank 400 reaching the set liquid level, stopping supplying the first water body and the second water body into the preparation tank 400;

[0053] The stirring device in the preparation tank 400 fully stirs the mixing water during preparation of the mixing water. The preparation tank 400 is provided with a first temperature detection sensor and a liquid level detection sensor. The first temperature detection sensor detects the temperature of the liquid (i.e. the mixing water) in the preparation tank 400, and the liquid level detection sensor detects the liquid level of the liquid in the preparation tank 400. The first pipeline 500 supplying the first water body is provided with a first electrically controlled on-off valve (e.g. a solenoid valve), and the second pipeline 600 supplying the second water body is provided with a second electrically controlled on-off valve (e.g. a solenoid valve). Both the first electrically controlled on-off valve and the second electrically controlled on-off valve are opened, the water supply flow rate of the first water body is less than that of the second water body, the first water body is continuously supplied into the preparation tank 400, and the second water body is intermittently supplied into the preparation tank 400 according to the temperature T5 of the mixing water in the preparation tank 400, so as to maintain the temperature of the mixing water prepared in the preparation tank 400 at T2. When the liquid level of the mixing water in the preparation tank 400 reaches a set liquid level, the first electrically controlled on-off valve and the second electrically controlled on-off valve are closed, and the supply of the first water body and the second water body into the preparation tank 400 is stopped.

[0054] In some examples, T6 is set to 1-3 degrees Celsius, and T7 is set to -3-0 degrees Celsius. It can be that T6 is set to 1 degree Celsius and T7 is set to -1 degree Celsius, or that T6 is set to 2 degrees Celsius and T7 is set to -2 degrees Celsius, or that T6 is set to 3 degrees Celsius and T7 is set to -3 degrees Celsius, etc. The above can achieve the purpose of the present application without departing from the design idea of the present application, and will not be described here again, and should all belong to the protection scope of the present application.

[0056] In some examples, as shown in Figure 3 The step of determining the temperature T2 of the mixing water to be prepared includes: determining T2 according to a preset data correspondence table of T1, K and T2.
