[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1 A high-pressure sintering furnace comprises a furnace body 1, a furnace door 2 is arranged on the front side of the furnace body 1, an electrode mechanism 3 is arranged on the side of the furnace body 1, the electrode mechanism 3 comprises an electrode flange, an insulating pad and a guide pipe with cooling water, which can keep the temperature of the electrode body within a safe range, more stable, and with better cooling effect. When the electrode mechanism 3 is energized, the inside of the furnace body 1 can be heated to realize the sintering function.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The furnace body 1 is fixedly connected to a furnace 6 inside, and a sintering rack 7 is movably connected to the inside of the furnace 6. One end of the sintering rack 7 extending into the furnace 6 is fixedly connected to a side scraper 8, and the lower surface of the side scraper 8 is fixedly connected to a converging scraper 9. The outer surfaces of the side scraper 8 and the converging scraper 9 are both in contact with the inner wall of the furnace 6 to facilitate scraping off the dust. The front and rear sides of the converging scraper 9 are both concave, and the dust can be gathered to the middle during the scraping process. The inner side of the furnace door 2 is fixedly connected to the front end of the sintering rack 7, and the lower surface of the furnace door 2 is fixedly A bracket 4 is connected, and a roller 5 is provided at the bottom end of the bracket 4. The roller 5 is supported on the ground to facilitate pulling the furnace door 2. A strip through hole 10 is penetrated through the lower surface of the furnace bladder 6. The strip through hole 10 is arranged just above the collecting box 11. In the process of pulling the furnace door 2, the side scraper 8 and the converging scraper 9 will scrape and clean the inner wall of the furnace bladder 6, and clean up dust and other debris that fall on the bottom inner wall of the furnace bladder 6. The concave converging scraper 9 can push the dust into the strip through hole 10, thereby achieving the purpose of cleaning the inner wall of the furnace bladder 6.

[0024] Reference Figure 1 , Figure 3 and Figure 4 A collecting box 11 is provided on the lower surface of the furnace body 6, and a knob 12 is movably connected to the front end of the collecting box 11, and a buckle 13 is fixedly connected to the front side of the knob 12, and a limiting rod 14 is fixedly connected to the outer surface of the knob 12. A limiting groove 15 is provided on the inner wall of the lower surface of the furnace body 6. When the collecting box 11 is pushed into the furnace body 1, the buckle 13 is rotated to drive the knob 12 to rotate, and then the limiting rod 14 is driven into the limiting groove 15, so that the collecting box 11 is installed stably. When the collecting box 11 needs to be removed, the buckle 13 can be rotated in the opposite direction to drive the limiting rod 14 to move out of the limiting groove 15.

[0025] The specific working principle of the utility model is as follows: when the device is in use, the furnace door 2 is pulled to drive the sintering rack 7 to slide out of the furnace body 1, and the objects to be sintered are placed on the sintering rack 7. After the furnace door 2 is closed, the electrode mechanism 3 is opened to realize sintering. Since the specific structure and working principle of the device are the existing technology well known to the staff in this field, no further elaboration is made here. The sintering rack 7 is fixedly connected to the furnace door 2, and a side scraper 8 and a converging scraper 9 are arranged on the rear side of the sintering rack 7. Therefore, in the process of pulling the furnace door 2, the side scraper 8 and the converging scraper 9 will scrape and clean the inner wall of the furnace 6, and clean up the dust and other debris that fall on the bottom inner wall of the furnace 6. The concave-shaped converging scraper 9 can push the dust into the strip through hole 10, thereby achieving the purpose of cleaning the inner wall of the furnace 6. Dust and impurities fall into the collection box 11 through the strip through hole 10. When the collection box 11 needs to be taken out, the buckle 13 is rotated in the reverse direction to drive the knob 12 to rotate, and then the limit rod 14 is driven out of the limit groove 15. At this time, pulling the buckle 13 can drive the collection box 11 to move out of the furnace body 1, which is convenient for centralized cleaning of dust and debris. After cleaning, the collection box 11 is pushed under the inner tank, and the buckle 13 is rotated forward to drive the knob 12 to rotate, and then the limit rod 14 is driven to enter the limit groove 15, so that the collection box 11 is installed stably.
