Description

TECHNICAL FIELD

[0001] The present application relates to the gypsum board manufacturing technology, in particular to an automatic temperature control device and method for gypsum board forming water. BACKGROUND

[0002] The gypsum slurry hydration temperature directly affects the hydration speed and the strength of the hardened gypsum product. In the hydration heat test and strength test, it can be found that when the exothermic quantity of the plaster reaches a very large value (i.e. the hydration heat reaches the ideal temperature point), the gypsum strength growth rate also reaches the ideal point. Therefore, there is a critical temperature point in the relationship between the compressive strength and the initial hydration temperature. Below this point, the hydration speed and the strength increase with the temperature. Above this critical point, the hydration speed and the strength decrease with the change of the initial hydration temperature. The uneven hydration of the slurry causes various quality problems.

[0033] As shown in Figure 1 The present application implements an automatic temperature control device 100 for gypsum board forming water, which includes a cold water delivery pipeline 1, a hot water delivery pipeline 2, and a mixed water delivery pipeline 3. The water outlet ends of the cold water delivery pipeline 1 and the hot water delivery pipeline 2 are connected to the water inlet end of the mixed water delivery pipeline 3. The output end of the mixed water delivery pipeline 3 is arranged to be connected to a gypsum slurry mixing machine 200. The hot water delivery pipeline 2 is provided with an adjusting valve 20 for adjusting the water output of the hot water delivery pipeline 2.

[0034] The automatic temperature control device 100 further comprises a first temperature sensing device 30 arranged on the mixed water delivery pipeline 3, a second temperature sensing device 10 arranged on the cold water delivery pipeline 1, and a third temperature sensing device 21 arranged on the hot water delivery pipeline 2.

[0035] The automatic temperature control device 100 further comprises a control device 4 connected with the first temperature sensing device 30, the second temperature sensing device 10, and the third temperature sensing device 21. The control device 4 in the embodiment of the application is a computer device. The first temperature sensing device 30, the second temperature sensing device 10, and the third temperature sensing device 21 are all temperature sensors.

[0036] In an exemplary embodiment, the control device 4 can control the opening degree of the regulating valve 20 according to the temperature information sensed by the first temperature sensing device 30. For example, a predetermined mixed water temperature is set first, and when the mixed water temperature is lower than the predetermined value, the opening degree of the regulating valve 20 is increased to increase the supply of hot water, and vice versa.

[0037] In another exemplary embodiment, the control device 4 can control the opening degree of the regulating valve 20 according to the temperature information sensed by the second temperature sensing device 10 and the third temperature sensing device 21. For example, the control device 4 can determine the mixed water outlet temperature according to the temperature sensed by the second temperature sensing device 10 and the third temperature sensing device 21, and when the mixed water outlet temperature is lower than the predetermined value, the opening degree of the regulating valve 20 is increased to increase the mixed water outlet temperature, and vice versa.

[0038] In another exemplary embodiment, the control device 4 can control the opening degree of the regulating valve 20 according to the temperature information sensed by the first temperature sensing device 30, the second temperature sensing device 10, and the third temperature sensing device 21.

[0039] In an exemplary embodiment, the control device 4 is arranged to control the initial opening degree of the regulating valve 20 according to the temperature signals sensed by the second temperature sensing device 10 and the third temperature sensing device 21.

[0040] After the initial opening degree adjustment, the control device 4 is further arranged to adjust the working opening degree of the regulating valve 20 according to the temperature signal sensed by the first temperature sensing device 30.

[0041] Since the delivery pipeline has a certain length, the unstable factors such as the flow and flow rate of hot water can easily cause the change of the mixed water outlet temperature, resulting in that the mixed water temperature does not meet the requirements. By monitoring the temperature of the mixed water, the accuracy of the mixed water temperature can be improved.

[0042] For example, the control device 4 can control the opening degree of the regulating valve 20 according to the water temperature of the cold, hot and mixed water delivery pipelines 1, 2 and 3. First, the initial opening degree of the regulating valve 20 can be controlled according to the water temperature of the cold and hot water delivery pipelines 1 and 2. When the water temperature of the mixed water delivery pipeline 3 does not reach the predetermined requirement, the opening degree of the regulating valve 20 can be continuously adjusted so that the mixed water temperature is closer to the preset temperature, and the mixed water temperature fluctuation at the start of the machine can be avoided to cause the quality problem of the gypsum mixture.

[0043] The automatic temperature control device 100 for the gypsum board forming water of the embodiment of the present application can achieve the predetermined temperature of the water outlet by setting the hot water delivery pipeline 2, setting the regulating valve 20 in the hot water delivery pipeline 2, and determining the opening degree of the regulating valve 20 according to the hot water temperature and the cold water temperature, or determining the opening degree of the regulating valve 20 according to the mixed water temperature, or determining the opening degree of the regulating valve 20 according to the hot water temperature, the cold water temperature and the mixed water temperature. In addition, the opening degree of the regulating valve 20 can be adjusted in real time according to the monitoring of the mixed water temperature, so that the optimal mixing temperature can be achieved.

[0044] The automatic temperature control device 100 for the gypsum board forming water of the embodiment of the present application can automatically adjust the temperature of the gypsum board forming water to adapt to the low temperature weather change in the autumn and winter seasons, so that the low hydration rate of the gypsum caused by the low temperature of the forming water can be avoided, and the temperature can be set artificially, and the system program can automatically control the temperature, so that the hydration temperature of the forming water can be controlled.

[0045] As shown in Figure 1 The automatic temperature control device 100 further comprises a switch valve 22 arranged on the hot water delivery pipeline 2, and the switch valve 22 is located upstream of the regulating valve 20. The switch valve 22 in the embodiment is an electromagnetic control valve.

[0046] The automatic temperature control device 100 of the embodiment of the present application can timely close the entire hot water delivery pipeline 2 when the automatic temperature control device 100 is powered off and stopped by arranging the switch valve 22 upstream of the regulating valve 20, so that the temperature change or the pipeline pressure or other risks of the downstream pipeline can be avoided.

[0047] As shown in Figure 1 The automatic temperature control device 100 of the embodiment of the present application further comprises a storage tank 5 connected to the input end of the cold water delivery pipeline 1, and the second temperature sensing device 10 is arranged in the storage tank 5. The storage tank 5 is used for storing cold water.

[0048] As shown in Figure 1As shown, the automatic temperature control device of the embodiment of the present application further comprises a water pump 31 arranged on the mixed water conveying pipeline 3, and the control device 4 is further connected with the water pump 31 to control the opening and closing of the water pump 31. The water pump 31 can control the flow and flow rate of the mixed water to maintain the uniformity of the mixed slurry. The water pump 31 is a precise metering pump. If the temperature of the mixed water flow exceeds the preset value range, the opening of the hot water valve is adjusted. Since the flow of the mixed water is fixed, the flow of the hot water changes, and the flow of the cold water changes accordingly. When the flow of the hot water increases, the flow of the cold water decreases accordingly.

[0049] As shown in the drawings, Figure 1 As shown, the automatic temperature control device of the embodiment of the present application further comprises a water pump 31 arranged on the mixed water conveying pipeline 3, and the control device 4 is further connected with the water pump 31 to control the opening and closing of the water pump 31. The water pump 31 can control the flow and flow rate of the mixed water to maintain the uniformity of the mixed slurry. The water pump 31 is a precise metering pump. If the temperature of the mixed water flow exceeds the preset value range, the opening of the hot water valve is adjusted. Since the flow of the mixed water is fixed, the flow of the hot water changes, and the flow of the cold water changes accordingly. When the flow of the hot water increases, the flow of the cold water decreases accordingly.

The control device draws a temperature change curve according to the temperature signal of the first flow sensing device 61, and the display device is used to display the temperature change curve.

[0051] The automatic temperature control device 100 of the embodiment of the present application further comprises an alarm device (not shown) connected with the control device, which is used to alarm when the temperature signal sensed by the first temperature sensing device 61 is lower than the preset value. The interval range value can be set, for example, the interval range of 30-35℃. If the temperature is lower or higher than the interval temperature value, the alarm is triggered.
