DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0020] Reference Figure 1 - Figure 9 The embodiment of the present application provides a spice kitchen steam conveying device capable of self-adjusting pressure, which comprises a control assembly and a conveying assembly, and the control assembly is composed of a pneumatic regulating valve 6, a pressure sensor 8, an on-off control valve 5, a pneumatic proportional valve 7 and a PCL control system. The pressure sensor 8 collects pressure data in a steam pipeline and feeds back in real time, and transmits the pressure value in the form of 4-20MA to the PLC control system. The PCL control system can judge whether the adjusting variable needs to be changed through an initial set value, and then convert the initial set value into a corresponding 4-20MA signal and transmit the signal to the pneumatic proportional valve 7. The pneumatic proportional valve 7 is used for controlling the opening degree of the pneumatic regulating valve 6, and the pneumatic regulating valve 6 is used for keeping the steam pressure at the initial set value. The conveying assembly comprises an air inlet pipe 1 and a conveying pipe 2, the conveying pipe 2 has a conveying diameter greater than that of the air inlet pipe 1, the right end of the air inlet pipe 1 is communicated with a conveying valve 3, the right side of the conveying valve 3 is communicated with a pressure reducing valve 4 through a pipeline, the right side of the pressure reducing valve 4 is communicated with the left side of an on-off control valve 5 through a pipeline, the left end of the conveying pipe 2 is communicated with the pneumatic proportional valve 7, the left side of the pneumatic proportional valve 7 is communicated with the right side of the pneumatic regulating valve 6 through a pipeline, and the left side of the pneumatic regulating valve 6 is communicated with the right side of the on-off control valve 5.
[0021] In work, the pressure sensor 8 collects the pressure data in the steam pipeline real-time feedback, the pressure value is transmitted to the PLC control system in the form of 4-20MA, the PLC control system adopts PID control technology, with PID control technology as the core, the steam pressure automatic control system is constructed, the PLC control system converts the 4-20MA signal transmitted by the pressure sensor 8 into pressure value, the PLC control system judges whether the adjusting variable needs to be changed through the initial set value, then converts into corresponding 4-20MA signal and transmits to the pneumatic proportional valve 7, to control the opening of the pneumatic regulating valve 6, when the monitored pressure value is less than the set pressure value, the pneumatic regulating valve 6 opens the corresponding opening, when the monitored pressure value is greater than the set pressure value, the pneumatic regulating valve 6 gradually closes, to keep the steam pressure at the initial set value, this way sets the reaction quickly and sensitively, effectively improves the response speed of pressure stabilization. When the device is used for steam delivery in the spice kitchen, the steam enters the delivery system through the inlet pipe 1, the initial pressure is adjusted by the delivery valve 3, and then it is delivered to the right through the delivery assembly. In the production process, the steam consumption of the spice kitchen steam system in the cuttage workshop is different, in order to meet the normal production demand, pressure reduction operation is needed, after pressure reduction by the pressure reducing valve 4, the volume of steam will increase, which will cause the flow rate in the delivery pipe 2 to increase, causing the scouring and noise of steam, and even causing damage to the pipeline and equipment. The delivery diameter of the delivery pipe 2 is greater than that of the inlet pipe 1, which directly affects the flow rate and pressure of the steam passing through the delivery pipe 2. The change of pipe diameter will directly affect the flow rate and pressure of the steam passing through the pipe. If the pipe does not increase after pressure reduction, the flow rate will increase, which not only affects the transmission distance and stability of the steam, but also increases the operating pressure of the pipe. On the contrary, appropriately increasing the diameter of the pipe can reduce the flow rate, making the flow of steam in the pipe more stable, reducing energy loss and pressure fluctuation. Therefore, appropriately increasing the diameter of the delivery pipe 2 can reduce the flow rate, making the flow of steam in the pipe more stable, reducing energy loss and pressure fluctuation, thereby improving the steam transmission efficiency.
