The high-pressure air pump 18 and the high-pressure air tank 19 are used as high-pressure air sources and supply high-pressure air to the high-pressure air nozzle, and the high-pressure air nozzle cleans coal slime blocked in the air vent through the high-pressure air. The high-pressure air pump 18 and the high-pressure air tank 19 belong to the prior art, and the detailed structure and the working principle thereof are not described herein.
As shown in fig. 3 and with reference to fig. 4-8, each of the first high-pressure gas nozzle 21 and the second high-pressure gas nozzle 55 includes a cylindrical housing 70, an upper cylinder opening and a lower cylinder opening of the housing 70 are respectively an airflow inlet and an airflow outlet, the housing 70 includes an upper cylinder 71 and a lower cylinder 72 which are arranged up and down, an inner diameter of the lower cylinder 72 is larger than an inner diameter of the upper cylinder 71, a flow guiding block seat 74 is slidably and sealingly disposed in the upper cylinder 71 of the housing 70, the flow guiding block seat 74 is barrel-shaped, a cylinder opening of the flow guiding block seat 74 is disposed toward the upper cylinder opening of the housing 70, the flow guiding block seat 74 includes a bottom cylinder wall 81 and a side cylinder wall 84, a first airflow hole 83 is disposed in the side cylinder wall 84, a guiding column 79 is connected to an outer side of the bottom cylinder wall 81, a flow guiding support frame 80 is disposed in the lower cylinder 72, a guiding hole 77 corresponding to the guiding column 79 is disposed on the flow guiding support frame 80, the guide posts 79 are inserted into the guide holes 77. Second airflow through holes 76 are formed in the diversion support frame 80, the second airflow through holes 76 penetrate through the diversion support frame 80 along the vertical direction, and therefore the second airflow through holes 76 can conduct the cylinder cavities of the lower cylinder body 72, which are located above and below the diversion support frame 80 respectively, namely, high-pressure gas above the diversion support frame 80 can flow to the lower portion of the diversion support frame 80 along the second airflow through holes 76 in the lower cylinder body 72. A spring 75 is connected between the flow guide plugging seat 74 and the flow guide support frame 80, an annular clamping table 82 is fixedly arranged at the lower end of the inner cylinder wall of the upper cylinder body 71, the flow guide plugging seat 74 is arranged in the annular clamping table 82 in a sliding sealing manner (namely, the upper cylinder body 71 is in sliding sealing with the flow guide plugging seat 74 through the annular clamping table 82), a radial flange 73 is fixedly arranged on the outer side of the barrel mouth of the flow guide plugging seat 74, a fixture block 78 is fixedly arranged at the lower end of the guide post 79, the fixture block 78 is positioned below the flow guide support frame 80, and an internal thread for connecting the high-pressure gas pipeline 20 is arranged at the upper end of the inner cylinder wall of the upper cylinder body 71. The end of the high-pressure gas pipeline 20 connected with the high-pressure gas nozzle is provided with an external thread, and the high-pressure gas pipeline 20 is fixedly connected with the high-pressure gas nozzle through a thread.
As shown in fig. 4, when the high-pressure gas nozzle is not supplied with high-pressure gas or the pressure of the high-pressure gas is not enough to compress the spring 75, the high-pressure gas nozzle is in a blocking state, that is, the diversion blocking seat 74 is in the blocking position, at this time, the diversion blocking seat 74 separates the high-pressure gas pipeline 20 from the outside, and prevents coal ash from entering the high-pressure gas pipeline 20, so that the high-pressure gas pipeline 20 can be prevented from being blocked due to the entry of the coal ash. As shown in fig. 5, high pressure gas is introduced into the gas flow inlet of the high pressure gas nozzle, and when the pressure of the high pressure gas reaches a certain level, the high pressure gas will compress the spring 75 downwards through the diversion blocking seat 74 (the high pressure gas acts on the upper portion of the bottom barrel wall 81 of the diversion blocking seat 74), and at the same time, the diversion blocking seat 74 slides downwards along the annular clamping table 82, when sliding to a certain position, the first gas flow hole 83 on the side barrel wall 84 enters into the lower barrel 72, at this time, the diversion blocking seat 74 is in the conducting position, because the inner diameter of the lower barrel 72 is larger than that of the upper barrel 71, when the diversion blocking seat 74 is in the conducting position, a gap exists between the side barrel wall 84 and the inner barrel wall of the lower barrel 72, so that the high pressure gas in the barrel cavity of the diversion blocking seat 74 enters into the gap through the first gas flow hole 83 and then enters into the barrel cavity of the lower barrel 72 above the diversion supporting frame 80 through the gap, then enters the cylinder cavity of the lower cylinder 72 below the diversion support frame 80 through the second air flow through hole 76, and finally is ejected from the air flow outlet. When cleaning is not needed, the high-pressure gas nozzle is disconnected from high-pressure gas, the compressed spring 75 is extended and reset, then the flow guide plugging seat 74 slides upwards along the annular clamping table 82 until the first gas through hole 83 on the side barrel wall 84 enters the barrel cavity of the upper barrel body 71, at the moment, the flow guide plugging seat 74 is in a plugging position, namely plugging is realized through sliding sealing between the flow guide plugging seat 74 and the annular clamping table 82, and as a result, coal ash outside the high-pressure gas nozzle cannot enter the high-pressure gas pipeline 20 through the flow guide plugging seat 74, so that the high-pressure gas pipeline 20 can be prevented from being plugged by the coal ash.
As shown in fig. 4 and in conjunction with fig. 5-8, when the diversion block seat 74 slides up and down along the annular clamping platform 82, the guide posts 79 also slide up and down along the guide holes 77 on the diversion support frame 80, and the guide posts 79 play a role in guiding. When the guide post 79 slides upwards to a certain position, the fixture block 78 fixedly arranged at the lower end of the guide post 79 abuts against the flow guide support frame 80 to prevent the guide post 79 and the flow guide plugging seat 74 from continuously sliding upwards, so that the plugging failure caused by the separation of the flow guide plugging seat 74 and the annular fixture table 82 is prevented. When the flow guide plugging seat 74 slides downwards to a certain position along the annular clamping table 82, the radial flange 73 abuts against the annular clamping table 82, and at the moment, the flow guide plugging seat 74 is at the maximum conduction position, namely the first air flow hole 83 completely enters the lower cylinder 72. The radial flange 73 is designed to abut against the annular clamping table 82, so as to prevent the high-pressure gas nozzle from being damaged due to the excessive pressure of the high-pressure gas, for example, when the pressure of the high-pressure gas is excessive, if the annular clamping table 82 is not provided, the diversion blocking seat 74 may completely enter the lower cylinder 72, and incline under the action of the high-pressure gas flow to be clamped in the lower cylinder 72, so that the blocking state cannot be recovered.
As shown in fig. 2, the utility model discloses net chain self-cleaning device when using, locates the high-pressure gas nozzle between net chain conveyor's the upper and lower conveyer belt to arrange the high-pressure gas nozzle conveyer belt down, when needing to wash, start high compression pump 18, high-pressure gas is from the high-pressure gas nozzle conveyer belt blowout down, then can clear away the coal slime that blocks up at the blow vent, thereby prevent that the blow vent on net chain conveyor's the conveyer belt from being blockked up by the coal slime, so that the normal clear of dry operation.
