Detailed Description
The utility model discloses a resistance orifice plate device capable of being assembled and disassembled on line, which can be assembled and disassembled on line and has low labor intensity during assembly and disassembly.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The utility model discloses a resistance orifice plate device capable of being replaced on line, which comprises: resistance pipe 2, intercommunication shell and orifice plate subassembly. Wherein the resistance pipe 2 is connected in the dust removal pipeline. The intercommunication shell sets up on resistance pipe 2, and along resistance pipe 2's radial extension to intercommunication shell and resistance pipe 2 interconnect, and the intercommunication. The communication housing has an opening 7. The orifice plate assembly comprises an orifice plate 1 and a closure plate 3 connected to each other. The orifice plate 1 can enter the resistance tube 2 through the opening 7 on the communication housing, and the orifice plate 1 can be fitted into the resistance tube 2. The closing plate 3 is used for sealing the opening 7. In order to ensure the firmness of the plugging, the closing plate 3 can be locked on the communication shell through a locking piece.
In the present invention, the orifice plate 1 and the resistance tube 2 are not integrally formed together by welding or the like. Therefore, when the resistance orifice plate device is replaced, only the orifice plate 1 needs to be replaced, the resistance pipe 2 does not need to be replaced, and the machine does not need to be stopped. The locking relationship between the closing plate 3 and the communication housing is released without stopping the machine, and thereafter the closing plate 3 and the orifice plate 1 are moved upward, thereby moving the orifice plate 1 out of the opening 7 of the communication housing. Then, a new orifice plate 1 is loaded into the resistance tube 2 through the opening 7 on the communication shell, the closing plate 3 is used for plugging the opening 7, and the closing plate 3 is locked on the communication shell. Because the machine does not need to be stopped when the machine is replaced, the dust removal efficiency is improved. The whole resistance orifice plate device does not need to be replaced, so the labor intensity is reduced.
It should be noted that the opening 7 in the communication housing needs to be small enough to pass through the port plate 1 for optimum positioning. In this way, the entry of outside air can be minimized when replacing the orifice plate 1. In addition, since the communication housing extends in the radial direction of the resistance tube 2, the moving path of the air flow is extended, so that the entrance of the external air can be further reduced.
It should be noted that the sealing performance of the orifice plate 1 and the resistance tube 2 does not need to be too high, and even a small amount of air flow passes through the gap between the orifice plate 1 and the resistance tube 2, the use of the orifice plate 1 is not affected. Therefore, the assembly relationship of the orifice plate 1 and the resistance pipe 2 does not affect the use function of the orifice plate 1 at all.
The locking relationship between the communication shell and the closing plate 3 is as follows: the communication shell comprises an end shell 4, the end shell 4 having an end plane. An opening 7 through which the orifice plate 1 passes is provided on the end plane of the end shell 4. The closure plate 3 has a flat surface which abuts the end flat surface. When the opening 7 is sealed, the closing plate 3 is attached to the end plane of the end shell 4, and then the closing plate 3 is locked to the end shell 4 by bolts. Shrouding 3 and end shell 4 have formed the structure of similar flange and blind flange, consequently can evenly twist the bolt on shrouding 3 all around, so powerfully guaranteed shrouding 3 and the fastness of being connected of end shell 4.
In order to improve the sealing, the utility model also provides a sealing ring on the end surface, or upper surface, of the end shell 4, which sealing ring is arranged around the opening 7 and is pressed between the end shell 4 and the closing plate 3.
The communication shell comprises, in addition to the end shell 4, a transition shell 5. One end of the transition shell 5 is connected with the end shell 4, and the other end is connected with the resistance pipe 2. The transition shell 5 is provided with an arc-shaped opening matched with the peripheral arc surface of the resistance pipe 2. Transition shell 5 card is on the periphery cambered surface of resistance pipe 2 to through welded mode with resistance pipe 2 welding as an organic whole. Transition shell 5 is provided with in the juncture with resistance pipe 2 and crosses the mouth, and this mouth is used for communicateing resistance pipe 2 and transition shell 5 to orifice plate 1 can pass in and out resistance pipe 2 through this mouth.
The shape of the gap is an arc-shaped gap extending along the circumferential direction of the resistance tube 2, and the shape of the transition shell 5 can be generally regarded as the shape of a motion track formed by the gap moving along the radial direction of the resistance tube 2. I.e. the transition shell 5 is saddle-shaped. So set up, can ensure that orifice plate 1 enters into resistance pipe 2 through transition shell 5 in, thereby can ensure simultaneously again that the opening of transition shell 5 is minimum further to reduce the entering of outside air
In order to resist the thrust generated on the orifice plate 1 when the airflow passes through the orifice plate 1 and prevent the orifice plate 1 from generating large-amplitude axial movement when the airflow impacts the orifice plate 1, the inner wall of the resistance pipe 2 is provided with a clamping groove, and the edge part of the orifice plate 1 is positioned in the clamping groove and is limited by the clamping groove.
Specifically, two blocks 10 are arranged on the inner wall along the axial direction of the resistance tube 2, and the two blocks 10 form a clamping groove. And, can set up a plurality of draw-in grooves along resistance pipe 2's circumference to improve the spacing dynamics to orifice plate 1.
The orifice plate assembly includes a transition plate 6 in addition to the orifice plate 1 and the closure plate 3. The transition plate 6 is matched with the inner cavity of the transition shell 5. One end of the transition plate 6 is connected with the pore plate 1, and the other end is connected with the closing plate 3. Because the transition plate 6 is matched with the transition shell 5, after the orifice plate 1 is arranged in the resistance pipe 2, the transition plate 6 can be blocked in the transition shell 5, so that the outside air can be effectively prevented from entering, and the sealing property is further improved.
The sealing plate 3, the transition plate 6 and the pore plate 1 can be welded into a whole in a welding mode, and the pore plate component can be integrally replaced when the pore plate 1 is replaced.
In addition, the following connection can be adopted: welding the sealing plate 3 and the transition plate 6, arranging a long bolt through hole 9 on the sealing plate 3, extending the long bolt through hole 9 to penetrate through the transition plate 6, and arranging a long bolt threaded hole 8 on the pore plate 1. The long bolt passes through the long bolt through hole 9 and then is screwed into the long bolt threaded hole 8. When the orifice plate 1 is replaced, the long bolts are loosened, the old orifice plate 1 is removed, and a new orifice plate 1 is bolted to the combination of the closing plate 3 and the transition plate 6. The replacement of the orifice plate 1 alone can save costs.
From the above description, it can be seen that only the orifice plate 1 needs to be replaced when the replacement is performed, and the resistance tube 2 does not need to be replaced. Therefore, both ends of the resistance tube 2 may be welded in the dust removing tube. So can improve resistance pipe 2 and the leakproofness of dust removal union coupling, prevent that the air current from leaking.
