Description

Technical Field

[0001] This utility model belongs to the field of sintering technology for the production of ceramic structural components, and particularly relates to a sintering device for the production of ceramic structural components. Background Technology

[0002] Ceramic structural components are advanced ceramics with excellent mechanical, thermal, and chemical properties, such as high temperature resistance, erosion resistance, corrosion resistance, high hardness, high strength, and low creep rate. They are commonly used in various structural parts.

[0003] For example, Chinese patent CN114469086A discloses a ceramic product sintering device. Heating tubes are installed on the inner walls of both sides of the sintering box. A rotating column is rotatably connected to the top of the sintering box, and a telescopic sleeve is installed at the bottom of the rotating column. A connecting and placing mechanism is provided at the bottom of the telescopic sleeve. A driving mechanism is provided on the sintering box to drive the connecting and placing mechanism to reciprocate and rotate. A lifting and positioning mechanism is also provided on the sintering box to guide the connecting and placing mechanism to move up and down. This invention, by symmetrically arranging two heating tubes on the side walls of the sintering box and allowing the ceramic product to rotate and reciprocate up and down within the sintering box, ensures that the ceramic product is heated evenly during sintering, resulting in high sintering efficiency and good sintering effect.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in its use. For example, when sintering ceramic structural components, it uses only one tray to hold the components. During sintering, it uses two heating tubes, meaning the ceramic components only receive even heating through rotation within the sintering chamber. Moving the components up and down does not achieve even heating and occupies significant space within the chamber, affecting sintering efficiency. Furthermore, some ceramic components are quite large, rendering the device unusable. Therefore, we propose a sintering device for producing ceramic structural components. Utility Model Content

[0006] The purpose of this invention is to provide a sintering apparatus for the production of ceramic structural components, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a sintering apparatus for producing ceramic structural components, including a sintering box, and further comprising:

[0008] A sealed door is rotatably mounted on a sintering box. An exhaust pipe is fixedly mounted on one side of the sintering box. Two fixed rods are fixedly mounted inside the sintering box. Several heating wires are fixedly mounted between the two fixed rods. A rotating rod is rotatably mounted inside the sintering box. Several limiting grooves are opened on the rotating rod. Several placement plates are slidably mounted on the rotating rod. A ring guardrail is fixedly mounted on the top of the placement plates.

[0009] A drive assembly located at the bottom of the sintering chamber and used to drive the rotating rod to rotate;

[0010] Four stops are respectively inserted into four limiting grooves and located at the bottom of four placement plates. Each stop has a sliding groove, and a slider is slidably installed in the sliding groove. One end of the slider extends into the rotating rod, and two springs are fixedly installed at the bottom of the slider and tightly welded to the inner wall of the sliding groove.

[0011] In this technical solution, during use, the operator can place the ceramic structural parts to be sintered onto several placement trays inside the sintering chamber. Then, the operator can rotate the sealing door and close it with a latch. Subsequently, several heating wires and drive components are activated. The heating wires will sinter the ceramics on several ring guardrails. Then, the drive components will drive the rotating rod to rotate slowly. The rotating rod will drive the placement trays to rotate, thereby rotating the ceramic structural parts on the placement trays. This allows the ceramic structural parts on the placement trays to be heated evenly. Then, the solenoid valve is opened, and the hot gas inside the sintering chamber will be discharged to the outside through the exhaust pipe.

[0012] When the ceramic structural component is large, the operator can pull the stop block at the bottom of the second-layer placement tray. As a result, the slider will be compressed and contract. At this time, the two springs at the bottom of the slider will be compressed and contract until the slider is fully inserted into the groove. Then, one end of the stop block can be inserted into the limiting groove between the first and second-layer placement trays. Under the action of the slider and the two springs, the stop block can be fixed in the limiting groove between the first and second-layer placement trays. At this time, the second-layer placement tray will move downward, increasing the distance between the second and third-layer placement trays, thus allowing larger ceramic structural components to be placed on the second-layer placement tray.

[0013] In the above technical solution, the driving component further includes:

[0014] Two gears are rotatably mounted at the bottom of the sintering box. One end of one of the gears passes through the top of the sintering box and is coaxially connected to a rotating rod. An L-shaped plate is fixedly mounted at the bottom of the sintering box and on one side of the other gear. A motor is fixedly mounted at the bottom of the L-shaped plate. The output end of the motor passes through the L-shaped plate and is coaxially connected to the other gear. The two gears are coaxially connected.

[0015] In this technical solution, when the motor is started, the output shaft of the motor will drive another gear to rotate slowly. Under the action of meshing, the other gear will drive one of the gears to rotate. Subsequently, the gear will drive the rotating rod to rotate, and the rotating rod will drive several placement plates to rotate, thereby driving the ceramic structural components on the placement plates to rotate, so that the ceramic structural components on the placement plates can be heated evenly.

[0016] In the above technical solution, one end of the gear is rotatably connected to the sintering box, and the output shaft of the motor is rotatably connected to the L-shaped plate.

[0017] In this technical solution, one end of the gear is rotatably connected to the sintering box, ensuring that the output shaft of the motor can rotate within the L-shaped plate.

[0018] In the above technical solution, furthermore, the plurality of the limiting grooves are linearly and equally spaced.

[0019] In this technical solution, the spacing between each placement plate can be adjusted by the action of several limiting slots.

[0020] In the above technical solution, the exhaust pipe is further connected to the inner cavity of the sintering box.

[0021] In this technical solution, it is ensured that the gas generated inside the sintering chamber can be discharged to the outside through the exhaust pipe.

[0022] In the above technical solution, the sealing door is further fixed to the sintering box by a pin.

[0023] In this technical solution, the sealing door is secured to the sintering box by means of a latch.

[0024] Furthermore, in the above technical solution, a solenoid valve is installed on the exhaust pipe.

[0025] In this technical solution, the solenoid valve is ensured to control the opening or closing of the exhaust pipe, thereby preventing dust from entering the sintering chamber through the exhaust pipe.

[0026] In the above technical solution, one end of the slider is further slidably connected to the rotating rod.

[0027] In this technical solution, it is ensured that one end of the slider can slide within the rotating rod.

[0028] The beneficial effects of this utility model are:

[0029] 1. The sintering device for producing ceramic structural components, through the cooperation of several placement plates, rotating rods, several heating wires, fixing rods and driving components, and under the action of several placement plates, improves the sintering efficiency of the sintering box for ceramic structural components, can make full use of the space inside the sintering box, and the ceramic structural components can also be heated evenly.

[0030] 2. The sintering device for producing ceramic structural components, through the cooperation of the rotating rod, limiting groove, stop block, slide, spring and slider, ensures that the spacing between each placement plate can be adjusted, thus accommodating ceramic structural components of different sizes and making it more convenient to use.
