Description

Technical Field

[0001] The utility model relates to the technical field of needle coke production, in particular to an intelligent hydraulic decoker used for needle coke production. Background Art

[0002] Hydraulic decokers are used in the hydraulic decoking system of delayed coking units, using high-pressure decoking water to remove coke from the coke drum. The high-pressure decoking water is rectified by the decoker's rectifier to form an orderly jet that is ejected from the nozzle to strike, crush, and remove the coke in the coke drum. However, conventional hydraulic decokers are unable to form a high-pressure water flow at the center during use, resulting in poor decoking performance and hindering the use of the device. Utility Model Content

[0003] The purpose of the present utility model is to provide an intelligent hydraulic decoker for needle coke production to solve the problems raised in the above background technology.

[0004] An intelligent hydraulic decoker for needle coke production comprises a fixed tube and a second fixed ring: a water outlet pipe is provided at the lower end of the fixed tube, a control mechanism is provided at the end of the fixed tube farther from the water outlet pipe, and the second fixed ring is provided at the end of the fixed tube closer to the water outlet pipe.

[0005] Preferably, a plurality of partitions are provided on the inner sides of the fixed pipe and the water outlet pipe, and a central pipe is provided on the inner sides of the partitions.

[0006] Preferably, a main discharge port is provided inside the central tube, and auxiliary discharge ports are provided between the partitions.

[0007] When the device is in use, the central tube and the partition will divide the water flow respectively, thereby dividing the water flow into the main discharge port and the auxiliary discharge port. The water can be discharged through the main discharge port and the auxiliary discharge port respectively, thereby flushing the surface of the needle coke and achieving decoking of the needle coke.

[0008] Preferably, the control mechanism includes a first fixing ring and a fixing gear. The first fixing ring is rotatably arranged on the outside of the fixing tube, and the fixing gear is arranged on the inner bottom of the first fixing ring.

[0009] When the device is in use, the first fixed ring is rotated to drive the fixed gear to rotate, based on which the opening size of the auxiliary discharge port is controlled, thereby controlling the drainage volume of the main discharge port by controlling the opening size of the auxiliary discharge port.

[0010] Preferably, the interior of the fixed tube is provided with fixed grooves at equal angles, a screw is rotatably provided inside the fixed groove, one side of the screw is connected to a pinion, and the other side of the screw is threadedly connected to a limiting mechanism, and the pinion and the fixed gear are meshed and connected.

[0011] When the device is in use, the fixed gear drives the pinion to rotate, and when the pinion rotates, it drives the screw rod to rotate, and the screw rod drives the limiting mechanism to move.

[0012] Preferably, the limiting mechanism includes a fixing rod and a baffle, the fixing rod thread is arranged on the outside of the screw rod, and the side surface of the fixing rod is connected to the baffle.

[0013] When the device is in use, the baffle will be limited by the fixed groove, so that the baffle will slide inside the fixed groove. When the screw rotates, since the baffle is limited, the screw will drive the fixed rod and the baffle to move, thereby adjusting the outlet size of the auxiliary discharge port by controlling the position of the baffle.

[0014] Preferably, a sealing ring is provided on the outer side of the baffle.

[0015] When the device is in use, the baffle is sealed by the sealing ring to prevent water from flowing into the fixing groove.

[0016] The beneficial effects of the utility model are:

[0017] 1. When the device is in use, the fixed gear can be rotated by rotating the first fixed ring. When the fixed gear rotates, it drives the pinion to rotate. When the pinion rotates, the screw rotates accordingly, thereby adjusting the position of the baffle, thereby controlling the opening size of the auxiliary discharge port, and based on this, controlling the opening size of the main discharge port.

[0027] A main discharge port 4 is provided inside the central tube 3 , and auxiliary discharge ports 6 are provided between the partitions 5 .

[0028] When the device is in use, the central tube 3 and the partition 5 will respectively divide the water flow, thereby dividing the water flow into the main discharge port 4 and the auxiliary discharge port 6. The main discharge port 4 and the auxiliary discharge port 6 can be used to discharge the material separately, thereby flushing the surface of the needle coke and achieving decoking of the needle coke.

[0029] The control mechanism includes a first fixing ring 7 and a fixing gear 8 . The first fixing ring 7 is rotatably arranged on the outside of the fixing tube 1 , and the fixing gear 8 is arranged on the inner bottom of the first fixing ring 7 .
