Technical Field

[0001] This patent relates to the field of carbon-ceramic composite material processing technology, specifically to an easy-to-operate carbon-ceramic composite material sintering furnace. Background Technology

[0002] By placing the carbon-ceramic composite material into a sintering furnace, under high temperature, the molecules or atoms of the carbon fiber and ceramic matrix gain enough energy to begin active movement, diffuse and fuse with each other, and through physical and chemical changes, the two are tightly bonded together to form a whole carbon-ceramic composite material.

[0003] In a carbonized ceramic sintering furnace with a cleaning structure proposed in publication number CN220567845U, impurities on the heating plate and the inner wall of the furnace can be cleaned by a brush, so as to avoid affecting the heat conduction of the heating plate and the sintering effect of the sintering furnace.

[0004] However, although a dust-collecting structure is installed at the bottom of the furnace body in the aforementioned document, the range that the dust-collecting structure can collect is limited. As a result, when the brush bristles clean the upper part of the furnace cavity, the dust and other impurities scraped off are easily re-adhere to the inner wall of the furnace, resulting in poor cleaning effect.

Detailed Implementation

[0020] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Please see Figure 1-3 This patent provides a technical solution: an easy-to-operate carbon-ceramic composite material sintering furnace, including a furnace frame 1 and a sintering furnace 2. The sintering furnace 2 is installed on the inner side of the furnace frame 1, and a feeding mechanism 3 is installed on the lower wall of the furnace frame 1. The feeding mechanism 3 is located below the sintering furnace 2.

[0022] By setting up the feeding mechanism 3, the carbon-ceramic composite material to be sintered can be directly placed on the placement platform 33 on the feeding mechanism 3, and then the feeding can be completed by controlling the electric push rod 31 to retract, which is very convenient.

[0023] The upper wall of the feeding mechanism 3 is provided with a threaded hole 4. A cleaning mechanism 5 is rotatably installed in the threaded hole 4. The cleaning mechanism 5 includes a screw 51, a cleaning scraper 52, a dust suction chamber 53, a vacuum cleaner 54 and a connecting groove 55. The screw 51 is screwed into the threaded hole 4. The upper wall of the screw 51 is provided with a cleaning scraper 52. The inside of the cleaning scraper 52 is provided with a dust suction chamber 53. The outer wall of the cleaning scraper 52 is provided with a connecting groove 55. The connecting groove 55 is connected to the dust suction chamber 53. The lower wall of the cleaning scraper 52 is provided with a vacuum cleaner 54. The vacuum cleaner 54 is electrically connected to an external power source. The input end of the vacuum cleaner 54 is inserted into the dust suction chamber 53.

[0024] Meanwhile, since impurities easily adhere to the inner surface of the sintering furnace 2 after sintering, it is necessary to clean the impurities in a timely manner to avoid affecting the heat conduction of the heating plate inside the furnace and the sintering effect of the sintering furnace 2.

[0025] This device can be installed on the feeding mechanism 3. The feeding mechanism 3 drives the cleaning mechanism 5 to move upward, thereby cleaning the inner wall of the furnace through the cleaning scraper 52 in the cleaning mechanism 5. At the same time, the cleaning scraper 52 is also equipped with a dust suction chamber 53 and a dust collector 54, which can directly collect the scraped impurities and prevent impurities from falling and causing secondary pollution to the sintering furnace.

[0026] Specifically, a flexible scraper 6 is installed on the outer wall of the cleaning scraper 52, and the flexible scraper 6 can fit against the inner wall of the sintering furnace 2.

[0027] In this paper, the flexible scraper 6 is made of high-temperature resistant rubber, which is used to clean the inner wall of the sintering furnace 2, avoiding damage to the heating plate on the inner wall of the sintering furnace 2. At the same time, the sintering furnace 2 needs to be cooled to room temperature before cleaning.

[0028] Specifically, the upper wall of the cleaning scraper 52 is provided with a through groove 7, the inner wall of the through groove 7 is provided with internal threads, the upper wall of the cleaning scraper 52 is provided with a cover 8, the outer wall of the cover 8 is provided with external threads, and the cover 8 is screwed into the through groove 7.

[0029] By providing a through groove 7 and a cover 8 on its cleaning scraper 52, the cover 8 can be removed when the dust suction chamber 53 needs to be cleaned, making operation convenient.

[0030] Specifically, the feeding mechanism 3 includes an electrically controlled push rod 31, a lower furnace cover 32, and a placement platform 33. The electrically controlled push rod 31 is inserted into the lower wall of the furnace frame 1 and is electrically connected to an external power source. There are two electrically controlled push rods 31, which are respectively located on the left and right sides of the sintering furnace 2. The lower furnace cover 32 is installed at the output end of the two electrically controlled push rods 31. The upper wall of the lower furnace cover 32 is equipped with a placement platform 33, on which the external carbon-ceramic composite material can be placed. The threaded hole 4 is located in the middle of the upper wall of the placement platform 33.

[0031] Specifically, a sealing ring 9 is fitted to the lower wall of the cover 8, and the sealing ring 9 can fit against the upper wall of the cleaning scraper 52.

[0032] By setting the sealing ring 9, the sealing between the cover 8 and the through groove 7 can be guaranteed when the cover 8 is installed in the through groove 7, so as to avoid air leakage and prevent impurities from flying out from the gap.

[0033] Specifically, the screw 51 includes a main rod body 511, a secondary rod body 512 and a connecting threaded cavity 513. The main rod body 511 is screwed into the threaded hole 4. The upper end of the main rod body 511 is provided with a connecting threaded cavity 513, and the secondary rod body 512 is screwed into the connecting threaded cavity 513.

[0034] The screw 51 is assembled from the main rod body 511 and the auxiliary rod body 512, so the position of the cleaning scraper 52 in the cleaning mechanism 5 can be adjusted so that it can be adapted to the height of the sintering furnace 2.

[0035] Working principle: The carbon-ceramic composite material to be sintered is placed on the placement platform 33 of the feeding mechanism 3. Then, the electric push rod 31 is retracted by controlling it to send the carbon-ceramic composite material into the sintering furnace 2. After the lower furnace cover 32 closes with the lower wall of the sintering furnace 2, the sintering furnace 2 is in a closed state. At this time, the inner cavity can be heated by the heating plate on the inner wall of the sintering furnace 2 to sinter the carbon-ceramic composite material.

[0036] After sintering, the staff can control the electric push rod 31 to push it out, and then remove the carbon-ceramic composite material from the placement platform 33. When the sintering furnace 2 cools to room temperature, the cleaning mechanism 5 is installed on the feeding mechanism 3 through the cooperation between the screw 51 and the threaded hole 4. The feeding mechanism 3 drives the cleaning mechanism 5 to move upward, thereby cleaning the inner wall of the furnace through the cleaning scraper 52 in the cleaning mechanism 5. At the same time, the cleaning scraper 52 is also equipped with a dust suction chamber 53 and a dust collector 54, which can directly collect the scraped impurities and prevent impurities from falling and causing secondary pollution to the sintering furnace.
