[0002] Petrochemical industry generally refers to the chemical industry that uses petroleum and natural gas as raw materials. It covers a wide range. Crude oil is cracked, reformed and separated to provide basic raw materials such as ethylene, propylene, butylene, butadiene, benzene, toluene, xylene, etc. The solid materials in petrochemical industry contain a certain amount of water and need to be dried.

A worm gear is meshedly connected to the side of the worm, and a fixed barrel sleeve is mounted on the top of the worm gear, located outside the heater. The reaction barrels can be clamped inside the fixed barrel sleeve via ridges and grooves. A second motor is fixedly connected to the top of the fixed column.

[0004] In order to ensure that the materials in the reaction barrel are heated evenly and to improve the drying efficiency, the above-mentioned public documents add a stirring component to stir the materials. Although this improves the drying efficiency to a certain extent, it still has some shortcomings in actual use. Since petrochemical solid materials have a certain viscosity during the drying process, although the stirring component can stir most of the materials, it is difficult to scrape off and stir the materials adhering to the inner wall of the reaction barrel, thereby still causing the problem of uneven heating of the materials. At the same time, the materials adhering to the inner wall of the reaction barrel will also affect the temperature transfer and the drying efficiency of other materials, making it very inconvenient to use.

[0027] The scraping device includes a connecting plate 18, which is movably connected to the bottom of the rotating rod 13. A scraper 19 is fixedly connected to the front and rear sides of the connecting plate 18 respectively, and a scraper bar 17 is fixedly connected to the top of the connecting plate 18 on both sides. The outer end of the rotating rod 13 is movably sleeved with a sleeve 15, and a connecting rod 16 is fixedly connected between the scraper bar 17 and the sleeve 15. A second reduction motor 20 is fixedly connected to the top of the second mounting plate 11, and the second reduction motor 20 is located behind the first reduction motor 12.

The first pulley 21 and the second pulley 22 are connected to each other by a belt 23.

[0028] The two scrapers 19 on the connecting plate 18 in the scraping device are both set at an angle. The connecting plate 18 itself does not contact the bottom of the material barrel 4, and the two scrapers 19 each occupy a little more than half the length of the connecting plate 18, so that no part will be missed when the scraper 19 scrapes the material at the bottom of the material barrel 4. The cross-section of the scraper strip 17 is triangular, and the side of the scraper strip 17 close to the inner wall of the material barrel 4 is arc-shaped and adapted to the inner wall of the material barrel 4, thereby scraping off the material adhering to the inner wall of the material barrel 4.

[0029] Two first slide rails 8 are fixedly connected to the top of the base 1, and a first mounting plate 9 is slidably connected to the top of the base 1 through the first slide rails 8. Two second slide rails 10 are fixedly connected to the front side of the first mounting plate 9, and the second mounting plate 11 is slidably connected to the front side of the first mounting plate 9 through the second slide rails 10. The first mounting plate 9 can be slidably connected to the base 1 through the slide rails 8, and the second mounting plate 11 can be slidably connected to the first mounting plate 9 through the second slide rails 10.

[0030] The front side of the first mounting plate 9 is fixedly connected to a supporting plate 24, and the supporting plate 24 is located below the second mounting plate 11. A first cylinder 25 is fixedly installed between the supporting plate 24 and the second mounting plate 11. A slide groove 26 is provided on the top of the base 1, and the slide groove 26 is located between the two first slide rails 8.

The first cylinder 25 can drive The second mounting plate 11 moves up and down. When the second mounting plate 11 moves down, the stirring device and the scraping device can be extended into the material barrel 4 to work. After the drying work is completed, the second mounting plate 11 can be pushed in the opposite direction to move the stirring device and the scraping device up and out of the material barrel 4. The first mounting plate 9 can be pushed forward and backward by the second cylinder 29 and the slider 27. When the first mounting plate 9 moves backward, it can move the second mounting plate 11 and the stirring device and scraping device on the second mounting plate 11 backward together. At this time, there is no obstruction above the material barrel 4, so the material barrel 4 can be taken out of the fixed seat 2.

[0031] The bottom edge of the base 1 is fixedly connected to a raised frame 30 , and the fixed block 28 and the second cylinder 29 are both located inside the raised frame 30 .

Through the cooperation of the limit strip 5 and the flange 6, the material barrel 4 in the fixed seat 2 will not rotate along with the operation of the stirring device and the scraping device.

[0033] A handle 7 is fixedly connected to the top of both sides of the material barrel 4, and the handle 7 is used to facilitate lifting the material barrel 4 upward.

[0034] Working principle:

[0035] When drying petrochemical solid materials, the materials are poured into the material barrel 4 and heated by the heater 3. During this period, the rotating rod 13 is driven to rotate by the first reduction motor 12. When the rotating rod 13 rotates, it can drive multiple stirring rods 14 to stir the materials inside the material barrel 4. At the same time, the second reduction motor 20 is also started. The second reduction motor 20 drives the sleeve 15 on the rotating rod 13 through the first pulley 21, the second pulley 22 and the belt 23. When the sleeve 15 rotates, it drives the two scraping bars 17 and the connecting plate 18 connected to the bottom of the two scraping bars 17 to rotate through the connecting rod 16. When the scraping bar 17 rotates along the inner wall of the material barrel 4, it can scrape up the materials adhered to the inner wall of the material barrel 4. When the connecting plate 18 rotates, it can scrape up the materials adhered to the bottom of the material barrel 4 through the two scrapers 19. The materials are fully stirred by the stirring mechanism, thereby accelerating the drying efficiency.

[0036] After drying is completed, the second mounting plate 11 is pushed upward by the first cylinder 25, and the stirring device and scraping device installed on the second mounting plate 11 are lifted up and separated from the material barrel 4, and then the slider 27 is pushed by the second cylinder 29, so that the first mounting plate 9 moves backward with the second mounting plate 11 and the stirring device and scraping device on the second mounting plate 11 until the stirring device and scraping device are no longer blocking the material barrel 4. At this time, the handle 7 can be grasped to lift the material barrel 4 out of the fixed seat 2 to discharge the material.
