Description

Technical Field

[0001] The utility model relates to the technical field of coking, in particular to a coking device with an anti-blocking structure. Background Art

[0002] Coking units are widely used in the petroleum refining and coal chemical industries. Their primary function is to break down heavy raw materials, such as oil or coal, into easily processed lighter oil products, high-quality crude tar, coke, and other by-products through high-temperature heating. Coking units play a crucial role in the oil refining and steelmaking industries, serving as a key means of increasing the added value of these two industries.

[0003] For example, a coking gas-liquid separator anti-blocking and cleaning device disclosed in Chinese patent publication number CN220056713U includes a vertically arranged gas-liquid separator tank body, a raw gas inlet, an exhaust outlet and a tar ammonia outlet are provided on the gas-liquid separator tank body, a plurality of ammonia branch pipes are horizontally and evenly arranged in the gas-liquid separator tank body, the outer ends of the ammonia branch pipes extend outside the gas-liquid separator tank body, the outer ends of the ammonia branch pipes are connected to the ammonia equalizing pipes, the ammonia equalizing pipes are connected to the ammonia main pipe, and a refinement nozzle is installed on the ammonia branch pipe; the beneficial effect of this utility model is that the tar adsorbed in the tank is effectively washed away by the ammonia branch pipes installed in the gas-liquid separator tank body, while improving its separation efficiency, it also avoids the blockage of the gas-liquid separator and the conveying pipeline after long-term operation, thereby ensuring the normal operation of the enterprise.

[0004] In the process of implementing this application, the inventor discovered that there are at least the following problems in this technology: although the above technical solution can flush the tar attached to the inner wall of the tank, it only flushes a fixed position through the nozzle, and it is difficult to completely flush the tar on the inner wall of the tank. Over time, the tar will accumulate more and more on the inner wall of the tank, and it is easy to cause blockage again. Therefore, further improvement can be made. Utility Model Content

[0005] In order to solve the above-mentioned problems, the present invention provides the following technical solutions: a coking device with an anti-blocking structure, comprising a tank body, an air inlet pipe connected to one side of the top of the tank body, a discharge port at the bottom of the tank body connected to a discharge pipe, a top cover embedded in the top of the tank body, a water pipe leading into the interior of the tank body connected to the center of the top cover, a lifting and cleaning assembly provided on the top of the tank body, and a rotating flushing assembly provided at the bottom of the lifting and cleaning assembly.

[0006] As an optimization, the lifting and cleaning assembly includes a limiting cylinder fixedly mounted on the top of the top cover and a threaded cylinder rotatably connected to the top of the top cover. A guide rod is slidably inserted inside the limiting cylinder, and the internal thread of the threaded cylinder is a saving screw. The bottom ends of the guide rod and the screw are fixedly mounted with a bottom plate, and a telescopic tube is connected between the top side of the bottom plate and the bottom end of the water pipe. The threaded cylinder rotates on the outside of the screw, which will cause the screw to drive the bottom plate to rise and fall, and then drive the rotating flushing assembly to move up and down inside the tank body. At the same time, the retractable telescopic tube will not hinder the water flow, so that the inner wall of the tank can be cleaned in all directions, and the accumulation of excessive tar in local dead corners can be avoided as much as possible.

[0007] As an optimization, the telescopic tube is a corrugated tube made of polyurethane.

[0008] As an optimization, a gear ring is fixedly installed on the top of the threaded barrel, a servo motor is fixedly installed on the top of the top cover, a gear is fixedly installed on one end of the output shaft of the servo motor, and the gear and the gear ring are meshed and connected. By starting the servo motor, the gear will be driven to rotate, and then the threaded barrel will be driven to rotate through the gear ring meshed with the gear.

[0009] As an optimization, the rotary flushing assembly includes a connecting pipe fixedly installed in the middle of the bottom side of the base plate, a drain pipe is fixedly installed at the bottom end of the connecting pipe, an oblique opening is opened in the middle of the drain pipe, and swivels are rotatably sleeved on the upper and lower sides of the drain pipe, and a spiral plate is fixedly installed between the swivels on both sides. Water is ejected outward through the oblique opening and will impact along the spiral plate, which will drive the swivel to rotate around the outside of the drain pipe, thereby rotating the water flow to flush the inner wall of the tank, thereby improving the cleaning range and efficiency.

[0010] As an optimization, six oblique openings are arranged in an array around the outer wall of the drain pipe, and the spiral plates are arranged corresponding to the oblique openings.

[0011] As an optimization, several balls are embedded on the opposite sides of the rotating rings. The upper and lower sides of the drain pipe have protruding outer edges, and the opposite sides of the outer edges are provided with an annular groove, and the balls are connected in the annular groove. By rolling the balls along the annular groove track, the friction caused by the rotation of the spiral plate can be reduced, wear is reduced, and water flushing is facilitated.

[0012] The beneficial effects of the utility model are:

[0013] The coking device with an anti-blocking structure has water flowing out from the oblique mouth, which will impact the spiral plate, causing the spiral plate to drive the rotating ring to rotate around the outside of the drain pipe, and then the water flow will rotate to flush the inner wall of the tank. At the same time, the gear ring drives the threaded barrel to rotate around the screw, so the bottom plate is driven downward by the screw, and then the drain pipe is driven downward synchronously, so the inner wall of the tank can be rotated and flushed from top to bottom in turn, thereby increasing the cleaning range and avoiding blockage by local tar accumulation that has not been cleaned.
