Abstract
Description
Technical Field
[0001] The utility model belongs to the field of vibration screening machinery, and mainly relates to a petroleum coke cooling and dehydration screen, in which the cooling and dehydration processes of petroleum coke can be completed in the same equipment. Background Art
[0002] Cooling and dehydrating petroleum coke is an important step in refining petroleum coke. The conventional operation sequence is to first cool and spray with water, remove dust with an external dust cover, and then cool and dehydrate through a high-frequency screen. Since the three processes are split operations, they not only occupy a large space and have high maintenance costs, but the connecting parts are also prone to leaking toxic steam. Since petroleum coke contains sticky impurities that are very easy to clog the sieve holes, the operation process is not only inefficient, but also difficult to ensure production safety. In order to save production costs, while effectively improving dehydration efficiency and production safety factors, it is necessary to improve the existing petroleum coke cooling and dehydration devices. Summary of the invention
[0003] The utility model aims to provide a petroleum coke cooling and dehydration screen, which integrates the cooling of petroleum coke, cleaning of silted sticky impurities that cause sieve plate clogging, dust prevention and dehydration operations, thereby reducing the cost of petroleum coke refining and improving the efficiency and safety of petroleum coke refining.
[0004] The utility model is realized by the following technical scheme, including a screen frame, a cooling water pipe, a steam desilting pipe and a sealing cover, both sides of the screen frame are connected with the vibration reduction device, and a vibrator is arranged above the screen frame, and its characteristics are: a sealing cover for preventing harmful steam leakage is arranged on the upper edge of the screen frame, and a feeding port on the sealing cover is sealed and connected with an upstream device; at the discharging end of the screen frame, a discharging port formed by the screen frame and the sealing cover is sealed and connected with a downstream device; a cooling water pipe is arranged in the screen frame below the sealing cover, near the feeding port; and a steam pipe for desilting is arranged next to a screen frame crossbeam below the screen surface.
[0005] The sealing cover is sealed and connected to the screen frame by rivets or bolts; an inspection manhole and an exhaust port are arranged on the top of the sealing cover.
[0006] The cooling water pipe passes through the side plate of the screen frame and is fixed to the cooling water pipe seat located below the sealing cover by U-shaped bolts I. The cooling water pipe is sealed and connected to the side plate of the screen frame; the number of cooling water pipes is 2 to 4.
[0007] The steam pipe passes through the side plate of the screen frame and is fixed to the steam pipe seat located next to the screen frame beam by U-shaped bolts II. The steam pipe is sealed and connected to the side plate of the screen frame. The number of steam pipes is 4 to 8.
[0008] The beneficial effect of the utility model is that when petroleum coke falls onto the screen surface from the feed inlet, the cooling water pipe located near the feed inlet can cool it, and at the same time, the dehydration screen can perform dehydration operation. When the viscous impurities contained in the petroleum coke block the screen holes, high-temperature steam can be sprayed through the steam pipe to reduce the adhesion of the impurities and then perform silt removal operation on the screen surface to ensure the smooth flow of the screen holes. A sealing cover is arranged on the upper edge of the screen frame, and the sealing cover is sealed and connected to the screen frame using Hook rivets or high-strength bolts. The feed inlet and the discharge port are sealed and connected with the upstream and downstream equipment, which effectively prevents the leakage of harmful steam and eliminates the pollution to the surrounding environment. The exhaust port on the sealing cover is connected with an exhaust device to actively suck out toxic gases, reduce the internal pressure of the screen machine, and prevent the toxic gases from leaking from the connection gap. The inspection manhole on the sealing cover can be used for installation and maintenance. The cooling and dehydration processes of petroleum coke are completed in the same equipment, which reduces the process, saves equipment, and improves production efficiency. It can be applied to the cooling and dehydration operations of petroleum coke in the petrochemical industry. BRIEF DESCRIPTION OF THE DRAWINGS
