[0002] The ion nitriding furnace is a device that ionizes a nitrogen-containing rarefied gas in a DC electric field in a vacuum container. The positive ions bombard the surface of metal parts to form a nitride layer to achieve surface hardening.

[0003] With the progress of society and the enhancement of environmental awareness, the requirements for the environmental performance of industrial equipment are becoming increasingly higher. Although the existing ion nitriding furnace has the function of filtering the generated gas before discharging it, in actual operation, the cleaning of the filter device is not convenient enough and usually requires manual cleaning. Therefore, a temperature-controlled ion nitriding furnace is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3A temperature-controlled ion nitriding furnace in this embodiment includes a furnace body 1, an air inlet pipe 2 is provided on the right side of the furnace body 1, a mounting shell 3 is provided on the right side of the air inlet pipe 2, a filter box 4 is provided at the bottom of the mounting shell 3, a filter plate 5 is provided inside the filter box 4, and an automatic cleaning mechanism 6 is provided inside the mounting shell 3.

[0021] The automatic cleaning mechanism 6 includes a motor 601, which is fixedly installed on the right side of the mounting shell 3. A cross bar 602 is fixedly installed at the output shaft of the motor 601. A bevel gear 1 603 is fixedly installed on the outer surface of the cross bar 602. The outer surface of the bevel gear 1 603 is meshed with a bevel gear 2 604. A rotating drum 605 is fixedly installed at the bottom of the bevel gear 2 604. A telescopic rod 606 is slidably installed on the right inner wall of the mounting shell 3, and a cleaning brush 607 is fixedly installed at the bottom of the telescopic rod 606.

[0022] When in use, first, the motor 601 drives the cross bar 602 to rotate, and the cross bar 602 drives the fan blades 608 to rotate, so that the gas generated in the furnace body 1 is drawn into the air inlet pipe 2. The gas in the air inlet pipe 2 enters the filter box 4 through the installation pipe, and after being filtered by the filter plate 5, the valve is opened and discharged from the exhaust pipe.

[0023] When the motor 601 drives the cross bar 602 to rotate, the cross bar 602 drives the bevel gear 1 603 to rotate, the bevel gear 1 603 drives the bevel gear 2 604 to rotate, and the bevel gear 2 604 drives the rotating drum 605 to rotate. Since the outer surface of the rotating drum 605 is provided with a slide 609, a slide rod 610 is slidably installed inside the slide 609. Through the sliding cooperation between the slide rod 610 and the slide 609 and the rotation of the rotating drum 605, the telescopic rod 606 is driven to move up and down, and the cleaning brush 607 of the telescopic rod 606 moves up and down, thereby cleaning the filter plate 5.

[0024] By providing the fan blades 608 , the fan blades 608 rotate to draw the gas in the furnace body 1 into the air inlet pipe 2 and into the filter box 4 for filtration, thereby preventing the gas from being directly discharged into the external environment.

[0025] A fixing plate located on the outer surface of the rotating drum 605 is fixedly installed between the left and right inner walls of the mounting shell 3. The fixing plate is provided to facilitate support for the rotating drum 605 and improve the stability of the rotating drum 605 during rotation.

[0026] By setting a slide 609 on the outer surface of the rotating drum 605, the sliding cooperation between the slide rod 610 and the slide 609 can drive the telescopic rod 606 to move up and down. One end of the telescopic rod 606 is connected to the slide 609, and the other end is slidably connected to the right inner wall of the mounting shell 3, ensuring that the telescopic rod 606 can drive the cleaning brush 607 to move up and down smoothly to improve the cleaning effect.

[0027] The temperature sensor monitors the temperature inside the furnace body 1 in real time and transmits the temperature signal to the thermostat. After receiving the signal from the temperature sensor, the thermostat adjusts the electric heating plate according to the preset temperature range. When the actual temperature is lower than the set value, the thermostat will start the electric heating plate for heating. When the actual temperature is higher than the set value, the thermostat will stop heating or reduce the heating power to maintain the temperature inside the furnace body 1 stable.

[0028] During implementation, follow these steps:

[0029] 1) When the motor 601 drives the crossbar 602 to rotate, the crossbar 602 drives the bevel gear 1 603 to rotate, the bevel gear 1 603 drives the bevel gear 2 604 to rotate, and the bevel gear 2 604 drives the rotating drum 605 to rotate;

[0030] 2) A slideway 609 is provided on the outer surface of the rotating drum 605, and a slide rod 610 is slidably mounted inside the slideway 609. The sliding cooperation between the slide rod 610 and the slideway 609, and the rotation of the rotating drum 605, drive the telescopic rod 606 to move up and down;

[0031] 3) Finally, the telescopic rod 606 and the cleaning brush 607 move up and down to clean the filter plate 5.

[0032] To sum up, the temperature-controlled ion nitriding furnace can filter the gas generated in the furnace body 1 by setting the filter box 4 and the filter plate 5, so as to prevent harmful gases from being directly discharged into the external environment. At the same time, the setting of the fan blades 608 can enhance the gas suction effect and ensure that the gas in the furnace body 1 can be fully introduced into the filter box 4 for filtering treatment.

[0033] In addition, the design of the automatic cleaning mechanism 6 realizes automatic cleaning of the filter plate 5. Driven by the motor 601, the cleaning brush 607 can move up and down, effectively removing impurities and blockages on the filter plate 5, thereby maintaining the continuous and efficient operation of the filter plate 5. This not only reduces the frequency and difficulty of manual cleaning, but also improves the overall operating efficiency and stability of the equipment, making cleaning work convenient and simple, achieving the effect of automatic cleaning without manual intervention.
