[0042] Example 1

[0043] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a calcining furnace for oil refining catalysts. The device includes a furnace body 1, a support plate 2 fixedly installed on the furnace body 1, and a calcining cylinder 3 installed inside the furnace body 1. The calcining cylinder 3 is rotatably connected inside the furnace body 1 and can fully absorb the heat of the furnace body 1. A transmission unit 4 is installed on the calcining cylinder 3, a crushing unit 5 is installed on the transmission unit 4, and a cleaning unit 6 is installed on the crushing unit 5. The transmission unit 4 includes a power component 41 installed on the support plate 2 and a rotating component 42 installed on the furnace body 1. The crushing unit 5 can be a crusher, used to stir and crush the catalyst inside the calcining cylinder 3 to ensure complete combustion while the transmission unit 4 is moving. The cleaning unit 6 can be a cleaning plate, used to clean the catalyst on the inner wall of the cylinder when the transmission unit 4 drives the calcining cylinder 3 to rotate.

[0044] The power component 41 includes a motor 411 fixedly mounted on the support plate 2, a transmission rod 412 fixedly mounted on the output shaft of the motor 411, a first shaft 413 fixedly connected to the transmission rod 412, a pulley 414 rotatably connected to the first shaft 413, the motor 411 driving the transmission rod 412 to rotate, the pulley 414 rotatably connected to the first shaft 413, and an annular groove 415 formed on the pulley 414.

[0045] Rotating component 42 includes a connecting block 421 fixedly installed on the outside of the furnace body 1, a first slide groove 422 formed on the connecting block 421, two sets of second shafts 423 fixedly connected to the first slide groove 422, rollers 424 rotatably connected to the two sets of second shafts 423, a sliding plate 425 slidably connected to the first slide groove 422, and second slide grooves 426 formed on the upper and lower sides of the sliding plate 425. The second slide grooves 426 are slidably connected to the rollers 424, providing a slide for the sliding plate 425, allowing the sliding plate 425 to move in a continuous path. The connecting block 421 slides smoothly back and forth via roller 424, and is fixedly connected to the slide plate 425 with teeth 427. The teeth 427 are located in the middle of the slide plate 425 and are flush with the slide plate 425. There is also an annular ring 428 fixedly connected to the slide plate 425, two sets of tube sleeves 429 rotatably connected to the furnace body 1, and a first gear 430 fixedly connected to the tube sleeves 429. The tube sleeves 429 are fixedly connected to the calcining cylinder 3, and the calcining cylinder 3 is rotatably connected to the furnace body 1 through the tube sleeves 429.

[0046] Among them, the pulley 414 is rotatably connected to the first shaft 413, and the annular ring 428 is slidably connected to the annular groove 415 on the pulley 414. The shape of the annular ring 428 is adapted to fit and engage with the annular groove 415. When the transmission rod 412 rotates, the pulley 414 will drive the annular groove 415 to move left and right, thereby driving the calcining cylinder 3 to achieve reciprocating rotation.

[0047] During use, when the motor 411 is started, the output shaft of the motor 411 will drive the transmission rod 412 to rotate, thereby driving the sliding plate 425 to slide left and right on the connecting block 421. Since the teeth 427 on the sliding plate 425 mesh with the first teeth 427 on the sleeve 429, and the sleeve 429 is rotatably connected to the furnace body 1, when the sliding plate 425 moves left and right, it will drive the calcining cylinder 3 to rotate back and forth on the furnace body 1.

[0048] The calcining cylinder 3 can rotate back and forth under the drive of the motor 411, which can make the catalyst inside the calcining cylinder 3 tumble continuously, fully absorb the heat of the furnace body 1, and be heated evenly.

[0049] Example 2

[0050] Reference Figure 4 , 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the crushing unit 5 includes a third shaft 51 rotatably connected inside the sleeve 429, a fixed frame 52 fixedly connected to the outside of the furnace body 1, the fixed frame 52 being fixedly connected to the third shaft 51, two sets of connecting boxes 53 being fixedly connected to the third shaft 51, the connecting boxes 53 being fixedly connected to the third shaft 51 and not moving, and the sleeve 429 being rotatably connected to the connecting boxes 53, and an agitating component 54 installed on the connecting boxes 53.

[0051] The stirring component 54 includes a second gear 541 fixedly connected to two sets of sleeves 429, a fourth shaft 542 rotatably connected between two sets of connecting boxes 53, the fourth shaft 542 passing through the connecting box 53, two sets of third gears 543 fixedly connected to the fourth shaft 542, the second gear 541 and the third gear 543 being connected by a chain 544. When the calcining cylinder 3 rotates, the chain 544 will drive the fourth shaft 542 to rotate, and a stirring blade 545 fixedly connected to the third shaft 51 and the fourth shaft 542. When the calcining cylinder 3 rotates, the chain 544 will drive the fourth shaft 542 to rotate, thereby driving the stirring blade 545 on the fourth shaft 542 to rotate, forming a stirring mechanism with the stirring blade 545 on the fixed third shaft 51, to crush and stir the catalyst in the calcining cylinder 3.

[0052] During use, when the motor 411 drives the calcining cylinder 3 to rotate, the connecting box 53 is fixedly connected to the third shaft 51, and the third shaft 51 is fixedly connected to the fixed frame 52, so the third shaft 51 will not rotate. Since the second gear 541 and the third gear 543 are connected by the chain 544, and the second gear 541 is fixedly connected to the sleeve 429, when the calcining cylinder 3 rotates, the chain 544 will drive the fourth shaft 542 to rotate, so that the stirring blade 545 on the fourth shaft 542 and the stirring blade 545 on the third shaft 51 will rotate relative to each other, thus crushing and stirring the catalyst in the calcining cylinder 3.

[0053] The catalyst inside the calcination cylinder 3 is automatically crushed and stirred to ensure complete calcination and prevent the catalyst from forming lumps.

[0054] The remaining structure is the same as that in Example 1.

[0055] Example 3

[0056] Reference Figures 6-8 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the cleaning unit 6 includes a support frame 61 fixedly connected to the connecting box 53, a telescopic groove 62 opened on the top of the support frame 61, a telescopic block 63 slidably connected to the telescopic groove 62, a spring 65 installed between the telescopic groove 62 and the telescopic block 63, one end of the spring 65 being fixedly connected to the telescopic groove 62, the other end of the spring 65 being fixedly connected to the telescopic block 63, and a scraping component 64 installed on the telescopic block 63. Under the action of the spring 65, the scraping component 64 is always in contact with the inner wall of the calcining cylinder 3 to scrape off the catalyst on the inner wall of the calcining cylinder 3 and prevent adhesion.

[0057] The cleaning component 64 includes a scraper 641 fixedly connected to the telescopic block 63. The scraper 641 is an arc-shaped plate that fits against the inner wall of the calcining cylinder 3. A scraping groove 642 is formed on the scraper 641. The scraping groove 642 is obliquely cut and its slope extends from the edge of the scraper 641 to the center. A fifth shaft 643 is fixedly connected to the scraper 641. A baffle 644 is provided on the fifth shaft 643.

[0058] During use, under the action of spring 65, scraper 641 will always be in contact with the inner wall of calcining cylinder 3. When calcining cylinder 3 rotates, scraper 641 will scrape the catalyst on the inner wall. Due to the oblique shape of scraper groove 642 on scraper 641, when encountering catalyst particles with larger particles and higher hardness, scraper groove 642 will increase the contact area with them, preventing telescopic block 63 from rebounding into telescopic groove 62. Under the action of baffle 644, it can prevent particles from accumulating on telescopic groove 62.

[0059] While the calcining cylinder 3 is rotating, the inner wall of the calcining cylinder 3 can be scraped to prevent the catalyst from sticking to the inner wall.

[0060] The remaining structure is the same as that in Example 2.

[0061] Example 4

[0062] Reference Figures 1-8 This is the fourth embodiment of the present invention, which provides a method for using a refining catalyst calcining furnace, comprising the following steps:

[0063] First, start the motor 411. The output shaft of the motor 411 will drive the transmission rod 412 to rotate, thereby driving the slide plate 425 to slide left and right on the connecting block 421. Since the teeth 427 on the slide plate 425 mesh with the first gear 430 on the sleeve 429, and the sleeve 429 is rotatably connected to the furnace body 1, when the slide plate 425 moves left and right, it will drive the calcining cylinder 3 to rotate back and forth on the furnace body 1.

[0064] When the motor 411 drives the calcining cylinder 3 to rotate, the connecting box 53 is fixedly connected to the third shaft 51, and the third shaft 51 is fixedly connected to the fixed frame 52, so the third shaft 51 will not rotate. Since the second gear 541 and the third gear 543 are connected by a chain, and the second gear 541 is fixedly connected to the sleeve 429, when the calcining cylinder 3 rotates, the chain 544 will drive the fourth shaft 542 to rotate, so that the stirring blade 545 on the fourth shaft 542 and the stirring blade 545 on the third shaft 51 will rotate relative to each other, and the catalyst in the calcining cylinder 3 will be crushed and stirred.

[0065] Finally, under the action of spring 65, scraper 641 will always be in contact with the inner wall of calcining cylinder 3. When calcining cylinder 3 rotates, scraper 641 will scrape the catalyst on the inner wall. Due to the oblique shape of scraper groove 642 on scraper 641, when encountering catalyst particles with larger particles and higher hardness, scraper groove 642 will increase the contact area with them, preventing telescopic block 63 from rebounding into telescopic groove 62. Under the action of baffle 644, it can prevent particles from accumulating on telescopic groove 62.
