Description

Technical Field

[0001] This invention relates to the field of gypsum powder calcination technology, and specifically to a gypsum powder calcination temperature control device. Background Technology

[0002] With the development and progress of the gypsum industry, the demand for gypsum powder is increasing, and the quality requirements for gypsum powder are also getting higher and higher. The production and manufacturing process of gypsum powder is also constantly improving. Dehydration is a key step in the production and processing of gypsum powder, and it is also the most difficult part to master.

[0003] For example, Chinese patent CN218755489U discloses a gypsum powder calcination temperature control device. This component, consisting of a calcination furnace, support frame, fixed plate, connecting rod, moving plate, temperature regulating pipe, regulating valve, heat conduction pipe, temperature detector, heating rod, and conical insert plate, allows the temperature regulating pipe to be connected to an external heat source when temperature regulation of gypsum is required. The temperature regulating pipe is then inserted into the gypsum through the conical insert plate, enabling the heat source to heat or exchange heat within the accumulated gypsum, thus improving the accuracy of temperature control. The device also includes a horizontal plate, support frame, through hole, longitudinal insertion and separation mechanism, motor, first gear, and second gear, which facilitate longitudinal movement of the temperature regulating pipe for temperature detection and regulation within the calcination furnace. However, in this design, temperature regulation via heat exchange during high-temperature calcination of gypsum powder is prone to heat loss. Therefore, we propose a gypsum powder calcination temperature control device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a gypsum powder calcination temperature control device, which solves the problem of heat loss that easily occurs when using heat exchange for temperature control during the high-temperature calcination of gypsum powder.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A calcination temperature control device for gypsum powder includes: a calcination chamber, a heating chamber on one side of the calcination chamber, two hinges fixedly installed on one side of the calcination chamber, and a sealing door fixedly installed at one end of each hinge; a temperature control component, disposed inside the calcination chamber for internal temperature control, a heating groove on the bottom surface of the calcination chamber, a heating plate fixedly installed inside the heating groove, an air inlet on one side of the calcination chamber, a heating fan fixedly installed on one side of the calcination chamber, an air supply pipe fixedly installed on one side of the heating fan, one end of the air supply pipe fixedly installed inside the air inlet, and an exhaust port on the top surface of the calcination chamber.

[0007] By adopting the above technical solution and setting up a heating plate, during use, the operator adds gypsum powder into the heating chamber and heats the gypsum powder through the heating plate, achieving the dehydration effect in the gypsum powder production and processing process. When the temperature inside the heating chamber is too high, a heating fan blows low-temperature gas into the heating chamber and then discharges the high-temperature gas inside the heating chamber through the exhaust hole, achieving the temperature control effect. Similarly, when the temperature inside the heating chamber is low, the heating fan heats the gas and then injects it into the heating chamber to improve the temperature control effect.

[0008] Preferably, the temperature control component includes: a mounting slot, which is formed on the inner top surface of the heating chamber, and a first electric push rod is fixedly installed inside the mounting slot, with a temperature sensor fixedly installed at one end of the telescopic shaft of the first electric push rod; two through holes, which are formed on the top surface of the calcining chamber, with a one-way valve fixedly installed inside each through hole, a gas supply pipe fixedly installed inside the through hole on the right side, and a return pipe fixedly installed inside the through hole on the left side; and a connecting box, which is fixedly installed on the top surface of the calcining chamber, with fixing slots on the left and right sides of the connecting box, one end of the gas supply pipe and one end of the return pipe fixedly installed inside the fixing slots, and a drying layer fixedly installed on one side of the inner surface of the connecting box.

[0009] By adopting the above technical solution and setting a temperature sensor, the internal temperature of the gypsum powder can be easily detected. When it is necessary to maintain the internal temperature of the heating chamber, the high-temperature gas generated by heating is opened by opening the one-way valve and then the gas supply pipe is used to fill the interior of the connecting box. After the high-temperature gas containing moisture is dried by the drying layer, the dried gas is returned to the interior of the calcining box through the return pipe, thereby reducing heat loss and waste.

[0010] Preferably, an exhaust pipe is fixedly installed inside the exhaust port, a dust collector is fixedly installed inside the exhaust pipe, and a valve is fixedly installed inside the exhaust pipe.

[0011] By adopting the above technical solution and installing a dust collector, the exhaust gas discharged from the exhaust pipe is cleaned to prevent air pollution and avoid affecting the working environment.

[0012] Preferably, a pushing groove is provided on one side of the heating chamber, and a second electric push rod is fixedly installed inside the pushing groove. A movable plate is fixedly installed at one end of the telescopic shaft of the second electric push rod, and a dispersing rod is fixedly installed on the bottom surface of the movable plate.

[0013] By adopting the above technical solution, a second electric push rod is set up, and the moving plate is moved by the telescopic shaft of the second electric push rod. The movement of the moving plate drives the dispersing rod to spread the gypsum powder inside the heating chamber, so as to avoid the gypsum powder from piling up and affecting the overall drying effect of the gypsum powder.

[0014] Preferably, a rotating groove is provided on one side of the inside of the dispersing rod, a drive motor is fixedly installed inside the rotating groove, and a stirring blade is fixedly installed at one end of the drive shaft of the drive motor.

[0015] By adopting the above technical solution, a drive motor is set up, and the drive motor drives the shaft to rotate, which in turn drives the stirring blades to rotate. The rotation of the stirring blades stirs and crushes the gypsum powder, preventing the gypsum powder from clumping and improving the drying efficiency.

[0016] Preferably, a display screen is fixedly installed on one side of the calcination chamber.

[0017] By adopting the above technical solution and setting up a display screen, staff can easily understand the temperature changes inside the heating chamber in a timely manner, thus improving practicality.

[0018] Preferably, a detection groove is provided on one side of the interior of the heating chamber, and a pressure sensor is fixedly installed inside the detection groove.

[0019] By adopting the above technical solution and setting up a pressure sensor to detect the internal pressure of the heating chamber, excessive internal pressure can be avoided, thus improving safety.

[0020] Preferably, a controller is fixedly installed on one side of the calcination chamber.

[0021] By adopting the above technical solution and setting up a controller, the temperature control device can be easily operated by staff, improving ease of use.

[0022] In summary, the present invention has the following main beneficial effects:

[0023] By installing a heating plate, workers add gypsum powder into the heating chamber during use, and the heating plate heats the gypsum powder, achieving the dehydration effect in the gypsum powder production and processing process. When the temperature inside the heating chamber is too high, a heating fan blows low-temperature gas into the heating chamber, and then the high-temperature gas inside the heating chamber is discharged through the exhaust hole, achieving the temperature control effect. Similarly, when the temperature inside the heating chamber is low, the heating fan heats the gas and then injects it into the heating chamber to improve the temperature control effect.

[0024] By setting a temperature sensor, the internal temperature of the gypsum powder can be easily detected. When it is necessary to maintain the internal temperature of the heating chamber, the one-way valve is opened to allow the high-temperature gas generated by heating to be filled into the interior of the connecting box through the gas supply pipe. After the high-temperature gas containing moisture is dried by the drying layer, it is then returned to the interior of the calcining box through the return pipe, reducing heat loss and waste.

[0025] By installing a dust collector, the exhaust gas is cleaned to prevent air pollution and maintain the working environment. A second electric push rod is installed, which moves a moving plate via its telescopic shaft. The moving plate then spreads the gypsum powder inside the heating chamber using a dispersing rod, preventing the powder from piling up and affecting the overall drying effect.

[0026] By installing a drive motor, the drive shaft rotates, driving the stirring blades to stir and pulverize the gypsum powder, preventing clumping and improving drying efficiency. A display screen allows staff to easily monitor temperature changes inside the heating chamber, enhancing practicality. A pressure sensor detects the pressure inside the heating chamber, preventing excessive pressure and potential hazards, thus improving safety. Attached Figure Description
