Abstract

The utility model belongs to the technical field of boiler equipment, specifically disclose a novel wear -resisting coal breakage pipe, riser, pipe chute and nozzle including connecting gradually are equipped with first seal box and second seal box on the inner wall of riser, be equipped with the third seal box in the latter half of pipe chute inner wall, the bottom of riser has still been seted up and has been prevented the plug -hole, prevents that the plug -hole outside is equipped with the arc blind plate, arc blind plate and riser bolted connection, be equipped with the pouring material in first seal box, second seal box and the third seal box. The utility model discloses simple structure, stand wear and tear and with low costs.

Description

Novel wear resistant fuel dropping pipe
Technical field
The utility model belongs to boiler equipment technical field, it relates to a kind of fuel dropping pipe, in particular to a kind of novel wear resistant fuel dropping pipe.
Background technology
Raw material carrys out coal and drops in fuel dropping pipe through feeder, fuel dropping pipe is made up of standpipe, inclined tube and nozzle three part usually, the shock abrasion of big block foreign material etc. in the coal particle agent raw material that its neutral tube and inclined tube are easily rapidly fallen, therefore raw coal meeting serious wear near the landing point of standpipe, inclined tube, once after abrasion sign occurs, will be absorbed in the vicious cycle mended repeatly and leak repeatly; Simultaneously owing to abrasion causes fuel dropping pipe inside can not keep smoothly, even there will be pit, in raw coal, the foreign material of attachment are very easily tangled, and then cause the problems such as fuel dropping pipe blocking so that I larger fluctuation very easily occurs at road burning. Owing to raw coal does accelerated motion in fuel dropping pipe, therefore raw coal reaches top speed at fuel dropping pipe nozzle place, and nozzle can be subject to telling the impact of coal particle, after nozzle is worn by mill, the water wall bend pipe arranged near nozzle can be subject to the abrasion of raw coal, causes great potential safety hazard.
Practical novel content
The purpose of this utility model is to provide the novel wear resistant fuel dropping pipe that a kind of structure is simple, wear-resistant and cost is low.
For achieving the above object, the utility model is by the following technical solutions: novel wear resistant fuel dropping pipe, comprises the standpipe, inclined tube and the nozzle that connect successively, and the inwall of standpipe is provided with the first seal box and the 2nd seal box; Lower part of inclined tube inwall is provided with the 3rd seal box; Anti-blocking hole has also been offered in the bottom of standpipe, is provided with arc blind plate outside anti-blocking hole; Arc blind plate and standpipe removably connect; First seal box, the 2nd seal box and the 3rd seal box are provided with mould material.
Further, the top of the first seal box exceeds the 2nd seal box.
Further, the first seal box, the 2nd seal box and the 3rd seal box are arc.
Further, the thickness of the first seal box, the 2nd seal box and the 3rd seal box is 2cm-10cm.
Compared with prior art, the beneficial effects of the utility model are as follows: the inwall of standpipe is provided with the first seal box and the 2nd seal box, reduce the speed of raw coal particle in standpipe, can be protected by standpipe inwall simultaneously, reduce the speed of its abrasion; Lower part of inclined tube inwall is provided with the 3rd seal box, reduces the speed of raw coal particle in standpipe, can be protected by inclined tube inwall simultaneously, reduces the speed of its abrasion; Anti-blocking hole has also been offered in the bottom of standpipe, is provided with arc blind plate outside anti-blocking hole, and arc blind plate is connected with standpipe bolt, when blocking occurs standpipe, is unloaded by arc blind plate, discloses the raw coal of blocking, and easy to operate, blocking-proof result is good; First seal box, the 2nd seal box and the 3rd seal box are provided with mould material, strengthen the wear resisting property of seal box, extend the work-ing life of fuel dropping pipe; The top of the first seal box exceeds the 2nd seal box, and two upper and lower two ends of seal box are in Different Plane, reasonable in design, reduce the length of seal box as far as possible, avoid the raw coal to standpipe to be impacted by property; First seal box, the 2nd seal box and the 3rd seal box are arc, and seal box coordinates closely with the inwall of standpipe, inclined tube, save space and easy for installation; The thickness of the first seal box, the 2nd seal box and the 3rd seal box is 2cm-10cm, reduces the thickness of seal box, prevents the raw coal through performance that it affects standpipe, inclined tube, reduces process for processing cost simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Novel wear resistant fuel dropping pipe, as shown in Figure 1, comprises the standpipe 6, inclined tube 1 and the nozzle 8 that connect successively, and the inwall of standpipe 6 is provided with the first seal box 4 and the 2nd seal box 5; Lower part of inclined tube 1 inwall is provided with the 3rd seal box 7; Anti-blocking hole 2 has also been offered in the bottom of standpipe 6, is provided with arc blind plate 3 outside anti-blocking hole 2; Arc blind plate 3 and standpipe 6 removably connect, with bolts in the present embodiment; First seal box 4, the 2nd seal box 5 and the 3rd seal box 7 are provided with mould material. The top of the first seal box 4 exceeds the 2nd seal box 5. First seal box 4, the 2nd seal box 5 and the 3rd seal box 7 are arc. The thickness of the first seal box 4, the 2nd seal box 5 and the 3rd seal box 7 is 2cm-10cm.
During work, after raw coal enters standpipe 6, it is subject to the obstruction of the 2nd seal box 5 and the first seal box 4, the decrease in velocity of raw coal particle, after falling into inclined tube 1, the obstruction being subject to the 3rd seal box 7, speed reduces further, reduces the abrasion to standpipe 6, inclined tube 1 and nozzle 8, when a jam does occur, back out bolt, arc blind plate 3 is taken off, disclose by the raw coal of blocking from anti-blocking hole 2.
