Description

Technical Field

[0001] The utility model relates to the technical field of steam curing kettle drainage, in particular to an intelligent control box for regulating the water level and temperature inside a steam curing kettle. Background Art

[0002] The curing kettle, also known as the autoclave, is a large pressure vessel with a large volume and heavy weight. The autoclave is widely used, and is widely used in the autoclave curing of aerated concrete blocks, concrete pipe piles, lime sand bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, high-strength gypsum and other building materials. A large amount of condensed water will be generated during the autoclave process and needs to be discharged in time, otherwise it will affect the efficiency of the autoclave. In addition, the temperature inside the autoclave needs to be monitored during the autoclave process to ensure that the temperature of the inside and outside parts of the autoclave is close to equilibrium, and then the heating is stopped and the body is steamed in a constant temperature state.

[0003] Most common ways of draining the steam curing kettle are to manually open the valve that enters the drain pipe to discharge the condensed water inside the steam curing kettle. When monitoring the temperature, a thermometer connected to the inside of the steam curing kettle is usually used to record the temperature inside the steam curing kettle. This process is labor-intensive and can easily cause damage to the operator during the operation. Therefore, an intelligent control box for regulating the water level and temperature inside the steam curing kettle is proposed to solve the above problems. Utility Model Content

[0029] The operation and observation module 5 includes a touch screen 51 , buttons 52 , and a knob 53 .

[0030] As a preference of this embodiment, the touch screen 51 is electrically connected to the transmission unit 34 , and the touch screen 51 receives the operating information of the liquid level sensor 4 , the button 52 , the knob 53 , the solenoid valve 7 and the temperature sensor 10 through the transmission unit 34 .

[0031] The touch screen 51 can display the water level inside the steaming kettle body 2 detected by the liquid level sensor 4, the temperature inside the steaming kettle body 2 monitored by the button 52, the knob 53, the solenoid valve 7 and the temperature sensor 10, as well as the temperature range and water level range pre-set in the control unit, for easy observation by the operator.

[0032] As a preference of this embodiment, button 52 is a reset switch and has a model number of XA2EA35. Button 52 has a 1NO+1NC output signal. Button 52 is electrically connected to signal processing unit 31. There are four buttons 52 and they are evenly distributed in groups of two. The two buttons 52 in the same group are divided into temperature control and water level control.

[0033] When the solenoid valve 7 needs to be opened, the operator can transmit the signal to the signal processing unit 31 by pressing the button 52 corresponding to the water level control, and then transmit the processed signal to the calculation unit 33 through the control unit 32, and then transmit the calculated signal for opening the solenoid valve 7 to the transmission unit 34.

When the temperature reaches the preset value, the button 52 corresponding to the temperature control is pressed to control the state of the heating device inside the steam chamber connected to the air inlet pipe 8, so that the temperature of the steam delivered into the interior of the steam curing kettle body 2 is in a constant temperature state.

[0034] As a preference of this embodiment, the knob 53 is a 2-position selection switch and has a model number of XB2BD25C. The knob 53 presents a 1NO+1NC output signal. The knob 53 is electrically connected to the signal processing unit 31 . There are four knobs 53 and they correspond to the four buttons 52 respectively.

[0039] The signal processing unit 31 classifies and organizes the received signals, and then transmits them to the control unit 32, which distributes them to the calculation area inside the calculation unit. The calculation unit 33 then transmits the signals that need to be displayed, started, etc. after calculation to the transmission unit 34, which transmits them, thereby facilitating the control of the entire device.

[0040] Working principle:

[0041] During the working process, the state of the solenoid valve 7 switch can be changed by the knob 53, whether it is a manual switch or an automatic switch. When the knob 53 is in the automatic switch state, when the liquid level sensor 4 detects that the accumulation height of the condensed water inside the steam curing kettle body 2 reaches the discharge requirement, the signal is transmitted to the signal processing unit 31, and then enters the calculation unit 33 through the distribution of the control unit 32, so that the calculation result is transmitted to the transmission unit 34, and the signal for opening the solenoid valve 7 can be transmitted to open the solenoid valve 7. When the information of multiple temperature sensors 10 enters the calculation unit 32, the average value is taken to obtain the temperature inside the steam curing kettle body 2. When the temperature reaches the preset range, the temperature of the steam entering the steam curing kettle body 2 is adjusted by signal transmission;

[0042] When the knob 53 is in the manual switch state, the operator needs to observe the water level and internal temperature of the condensed water accumulated inside the steam curing kettle body 2 through the touch screen 51, and then press the button 52 to transmit a signal requiring drainage or heating.
