Abstract
The utility model relates to a telescopic pipe used for conveying pulverized coal. The telescopic pipe used for conveying the pulverized coal conveys the pulverized coal, and meanwhile a combustor can move back and forth. The telescopic pipe used for conveying the pulverized coal mainly solves the problem that due to the fact that currently, a coal conveying channel on the tail portion of a pulverized coal combustor used for a rotary kiln is a rubber flexible pipe, service life is short, replacement is frequent after abrasion, and production is severely influenced. According to the telescopic pipe used for conveying the pulverized coal, an inner sleeve is installed in an outer sleeve, the inner sleeve is connected with the outer sleeve through a flange, and universal joints are respectively fixed on the other ends of the inner sleeve and the outer sleeve. The inner sleeve and the outer sleeve can move in the axial direction correspondingly. Due to the fact that the universal joints are arranged on the inner sleeve and the outer sleeve, the errors of horizontal and vertical distance between a pulverized coal conveying end and a pulverized coal inlet end of the combustor can be compensated. Due to the fact that abrasion materials are arranged on the conical surfaces of the universal joints, service life is prolonged, and the replacement is convenient.
Description
Technical field
The utility model relates to a kind of telescopic tube for delivery of coal dust, and the pipeline that relates to specifically pulverized coal conveying adopts a telescopic tube, and burner can be realized again the telescopic tube that moves forward and backward when reaching pulverized coal conveying.
Background technique
In the metallurgical and building material industry, rotary kiln is very high to the requirements for pipes of delivering coal of afterbody with pulverized coal burner, should wear-resisting and continuous pulverized coal conveying, guarantee that again burner moves forward and backward.What at present rotary kiln delivered coal that pipeline extensively adopts with the pulverized coal burner afterbody is rubber hose, because the rubber hose cycle in working life is short, the rear frequent of wearing and tearing has had a strong impact on normal production.Particularly in metallurgy industry, sometimes for effective preveting kiln ringing, must adopt the technological requirement of the real-time movement of pulverized coal burner intermittent, under this specific condition, both effectively prevented ring formation, reach again reliable and stable and produce continuously, in the pipeline of pulverized coal conveying, use rubber hose can not reach above-mentioned requirements.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and propose a kind ofly have a long service life, convenient maintenance and replacement, both can realize the smooth and easy conveying of coal dust, also can compensate the upper error of on-the-spot power transportation pipe horizontal and vertical distance, realize the deflection of several angle, and be implemented in the telescopic tube that slides along the front and back of internal and external casing axis in the deflection angle.
Technical solution of the present utility model is: the telescopic tube for delivery of coal dust is: inner sleeve is installed in the outer sleeve, adopts flange to connect between the inside and outside sleeve pipe, is fixed with respectively a universal joint on the other end of inside and outside sleeve pipe.
Be provided with sealing gasket between the inside and outside cover described in the technical solution of the present utility model.
Universal joint inner conical surface described in the technical solution of the present utility model circumferentially is pasted with wear resistant ceramic chip, is provided with sealing gasket between wear resistant ceramic chip and the universal joint spheroid.
[0007]The intermediate member that the utility model telescopic tube is carried as coal dust in the buner system is installed in burner and delivers coal between the entrance, and two ends are with flange pairing connection.
The utility model has the advantages that:
1, the circumferential part easy to wear of the inner conical surface of universal joint is provided with high-abrasive material, has prolonged working life;
2, utilize the rotational characteristic of universal joint, can compensate horizontal and vertical range error certain between coal dust delivery end and the burner coal powder entrance end;
3, can be implemented in and move forward and backward along the internal and external casing axis in the deflection angle, satisfy the kiln condition in real time mobile requirement of burner, maximum can realize the deflection of 15 ° of taperings;
4, connect convenient maintenance and replacement between each parts with flange.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, core component of the present utility model is universal joint 2, universal joint 2 is made of spheroid 5 and cylindrical shell, adopt two universal joints 2 in the utility model, it is connected with an end of outer sleeve 6 by flange at a universal joint 2, another universal joint 2 is connected with an end of inner sleeve 7 by flange, the other end of inner sleeve 7 is installed in the outer sleeve 6 and connects with flange, can move to axial between the inside and outside sleeve pipe 7,6, be provided with sealing gasket 4 between inside and outside sleeve pipe 7,6, sealing pad 4 can adopt a mao bonding die; Inner conical surface at universal joint 2 circumferentially is pasted with wear resistant ceramic chip 3, in order to guarantee the sealing between wear resistant ceramic chip 3 and the universal joint, is provided with sealing gasket 4 between wear resistant ceramic chip 3 and universal joint 2 spheroids 5; During use, the utility model is installed in burner 1 and delivers coal between the entrance 8, the cylindrical shell that universal joint 2 inner conical surfaces is pasted with wear resistant ceramic chip 3 is connected with burner 1, and the cylindrical shell of another universal joint 2 by itself is connected with the pulverized coal channel at entrance 8 places that deliver coal; The characteristic that the utility model utilizes universal joint 2 to rotate, can realize compensating the deflection of several angle and distance, can relative sliding between outer sleeve 6 and the inner sleeve 7, realized the requirement that moves forward and backward of burner, the reasonable use of wear resistance ceramic tube 3 and sealing gasket 4, prolonged the working life of telescopic tube and prevent internal and external casing 7,6 and universal joint 2 do not leak coal when moving or rotating, reached reliable and stable operating characteristic, adopt flange to be connected with bolt between each parts of sleeve pipe, when component wear or damage are arranged, convenient maintenance and replacement.
