Problems solved by technology

Since the water turbine (water motor) can only provide one set rotation speed, and the coke cutter has two working conditions of drilling and coke cutting, so one rotation speed of the water turbine (water motor) is the same as that of the coke cutter drilling Matching the two working conditions of coke cutting must not make the coke cutter in the drilling or coke cutting conditions reach the best state
In addition, due to the long axial dimension (about 2.5 meters) of the equipment combination connected externally with the water turbine (water motor) and the coke cutter, the contact area between the equipment combination and the coke will be reduced during the decoking process when the coke in the tower collapses. Large, not conducive to lifting buried drill

Embodiment Construction

[0018] Such as Figure 1 to Figure 7 shown. The present invention consists of a drill pipe connecting part 1 , a hydrodynamic part 9 , a decoking part 12 , a throttling speed regulating part 10 and a switching part 13 to form a self-rotating coke cutter. From top to bottom, the drill pipe connecting part 1 is connected to the hydrodynamic part 9, the throttling speed regulating part 10 is arranged between the hydrodynamic part 9 and the decoking part 12, and the switching part 13 is located in the axial cavity of the decoking part 12 .

[0019] The drill pipe connecting part 1 is composed of an anti-loosening flange 2 , a connecting seat 3 , an elastic element 4 , a sealing seat 5 and a sealing element 6 . The uppermost end of the drill pipe connecting part 1 is the anti-loosening flange 2, the anti-loosening flange 2 is connected with the connecting seat 3 through bolts, the through-hole thread of the connecting seat 3 is connected with the drill pipe, the connecting seat 3...

Abstract

The invention provides an automatic rotation type coke cutter, belongs to the technical field of hydraulic decoking, and mainly solves the problem that two working conditions including drilling and coke cutting cannot reach an optimal matching state since an existing coke cutter only can provide one pre-set rotary speed. The automatic rotation type coke cutter is mainly characterized by comprising a drilling rod connection part, a water power part, a throttle governing part, a decoking part and a switching part, wherein the throttle governing part is arranged between the water power part and the decoking part; the switching part is arranged in an axial cavity of the decoking part; the upper rend of a switching shaft is connected with a switching disc by a spline; the switching disc is provided with two switching blocks; a water supply flow channel of the decoking part is an inner annular flow channel; four or two coke cutting nozzles are distributed at the periphery of the water supply flow channel and four drilling nozzles are distributed at the bottom end of the water supply flow channel. The automatic rotation type coke cutter has the characteristics of providing rotation speeds meeting the two working conditions including the drilling and the coke cutting respectively and being good for removal of buried drilling when coke in a tower collapses and is power equipment capable of being widely applied to a hydraulic decoking process in the coke tower.

Description

technical field [0001] The invention belongs to the technical field of hydraulic decoking. In particular, it relates to a power decoking device used in a hydraulic decoking process in a coke tower. Background technique [0002] At present, the power equipment in the tower used for hydraulic decoking in the coke tower adopts the combination of water turbine (water motor) and coke cutter. Since the water turbine (water motor) can only provide one set rotation speed, and the coke cutter has two working conditions of drilling and coke cutting, so one rotation speed of the water turbine (water motor) is the same as that of the coke cutter drilling Matching the two working conditions of coke cutting, it is inevitable that the coke cutter in the drilling or coke cutting working conditions cannot reach the best state. In addition, due to the long axial dimension (about 2.5 meters) of the equipment combination connected externally with the water turbine (water motor) and the coke c...
