Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The embodiment of the invention provides a blowing pipe of a rotary blowing bag-type dust collector, which comprises the following components in percentage by weight as shown in figure 1: stator tube 1 and rotor tube 6 in butt joint; the stator tube 1 is provided with a stator sealing disc 4 at the position butted with the rotor tube 6, and the rotor tube 6 is provided with a rotor sealing disc 5 at the position butted with the stator tube 1; the stator sealing disk 4 with the rotor sealing disk 5 is discoid, the stator sealing disk 4 with the rotor sealing disk 5 forms the cockscomb structure interlock on the plane of butt joint. It should be noted that the zigzag bite is a staggered bite structure, and in a preferred embodiment, the zigzag bite is shaped like a great wall. According to the invention, the sealing between the rotor pipe 6 and the stator pipe 1 of the blowing pipe of the rotary blowing bag-type dust remover is changed from axial sealing to radial sealing, and the sealing surface is designed to be a zigzag sealing structure, so that the leakage between the contact surfaces of the rotor pipe and the stator pipe can be avoided when high-pressure pulse compressed air flows through the sealing surface, and the sealing structure has good sealing property.
In one aspect of the embodiment of the present invention, the engaging teeth on the stator sealing disk 4 are concentric circles uniformly distributed at intervals with the center of the stator tube as the center; the meshing teeth on the rotor sealing disk 5 are concentric circles which are uniformly distributed at intervals and take the center of the rotor pipe as the center of a circle. The concentric design of the teeth ensures the most advantageous sealing effect against the interior. Preferably, after the meshing teeth on the stator sealing disk 4 and the meshing teeth on the rotor sealing disk 5 are meshed, a gap is formed between the adjacent meshing teeth, and grease is filled in the gap. When the rotor pipe 6 and the stator pipe 1 are not concentric due to thermal deformation caused by the change of the environmental temperature, the clearance between adjacent meshing teeth in the radial sealing structure can be adjusted in a self-adaptive manner to eliminate the problem of non-concentricity, so that the clamping stagnation of the rotor pipe 6 is avoided, and the operation failure rate is reduced; meanwhile, the space of the gap can be blocked by filling the grease, and the effect of ensuring sealing is achieved.
In one aspect of an embodiment of the present invention, the stator sealing disk 4 is removably attached to the stator tube 1; wherein the nozzle of the stator tube 1 is inserted into the rotor tube 6 over the interface between the stator sealing disk 4 and the rotor sealing disk 5. This arrangement further enhances the sealing effect by blocking the abutment surface between the stator sealing disk 4 and the rotor sealing disk 5 by means of said stator tube 1 partially protruding into the rotor tube 6.
Preferably, the stator sealing disk 4 is detachably connected to the stator tube 1 by means of a detent bolt 2. When the sealing surface needs to be overhauled, the rotation stopping bolt 2 can be detached, the sealing disk 4 of the stator is lifted along the axial direction, the rotor sealing disk 5 and the stator sealing disk 4 are mutually separated, and online overhauling can be achieved, and the effect of convenient maintenance is achieved.
Further preferably, the rotor seal disk 5 and the rotor pipe 6 are integrally connected, and the integral connection is beneficial to enhancing the connection strength between the rotor seal disk 5 and the rotor pipe 6, resisting the torque generated during rotation and prolonging the service life.
Further preferably, a sealing ring 3 is arranged between the stator sealing disk 4 and the stator tube 1, so as to further guarantee sealing.
In conclusion, the rotary blowing bag-type dust remover realizes the sealing between the rotor pipe 6 and the stator pipe 1 of the rotary blowing bag-type dust remover blowing pipe, and overcomes the defects of poor sealing effect, easy clamping stagnation, incapability of overhauling a sealing surface on line and the like. The sealing device has the advantages of good sealing performance, convenience in maintenance, low failure rate and the like.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
