Specifically, please refer to fig. 1 and 2, a cement clinker silo top dust collecting device includes an air inlet pipe 1 communicated with a clinker silo top, an outer wall of the air inlet pipe 1 is sleeved with a water cooling pipe 2, a water cooling cavity 3 is arranged between an inner wall of the water cooling pipe 2 and an outer wall of the air inlet pipe 1, a water inlet pipe 4 communicated with the water cooling cavity 3 is arranged at a bottom side of the water cooling pipe 2, a water outlet pipe 5 communicated with the water cooling cavity 3 is arranged at a top wall of the water cooling pipe 2, an air outlet end of the air inlet pipe 1 is communicated with a bag-type dust collector 6, an ash hopper 7 of the bag-type dust collector 6 is arranged at a bottom surface, and a material blocking device 8 is installed at a discharge port of the ash hopper 7.

Wherein, a large amount of dust-containing air flow generated in the feeding process in the clinker silo is sucked through the air inlet pipe 1 communicated with the top of the clinker silo, then the water inlet pipe 4 is communicated with the water supply equipment and the water outlet pipe 5 is communicated with the water discharge equipment in the process that high-temperature dust-containing air flow enters the bag-type dust remover 6 through the air inlet pipe 1, so that the water cooling cavity 3 is filled with cooling water in the process of continuously supplying water by the water supply equipment, the cooling water in the water cooling cavity 3 exchanges heat with the high-temperature air flow in the air inlet pipe 1, the high-temperature dust-containing air flow passing through the air inlet pipe 1 is cooled by the cooling water, the dust-containing air flow can be cooled once in the process of entering the bag-type dust remover 6 through the air inlet pipe 1, the long-time treatment of the high-temperature dust-containing air flow in the bag-type dust remover 6 is effectively avoided, and the service life of the bag-type dust remover 6 is greatly reduced, and frequent maintenance.

Further, please refer to fig. 3 and 4 again, the material blocking device 8 includes a material discharging pipe 81 communicated with the discharging end of the ash hopper 7, a material blocking plate 82 is movably disposed in the material discharging pipe 81, the end of the material blocking plate 82 is connected with a counterweight device 83, the counterweight device 83 is used for controlling the material blocking plate 82 to move up and down, a limiting groove 84 is disposed on the inner wall of the material discharging pipe 81, two ends of the material blocking plate 82 are embedded into the limiting groove 84, and the limiting groove 84 is used for preventing the material blocking plate 82 from moving up and down excessively.

Like this, the material gets into down the unloading pipe 81 through ash bucket 7 from last, and a large amount of materials hold on striker plate 82, after the material on striker plate 82 accumulated certain volume, promptly after the material weight on striker plate 82 is greater than the weight of counterweight device 83, striker plate 82 begins the motion, let counterweight device 83's counter weight end rebound, in striker plate 82 rebound, can let the material above striker plate 82 continue rebound promptly, until discharging from unloading pipe 81, realize the purpose of unloading, material on striker plate 82 is at the in-process of letting out, its continuous reduction back of weight, after material weight on striker plate 82 is less than counterweight end weight on counterweight device 83, counterweight end rebound, striker plate 82 rebound, thereby let material on striker plate 82 stop unloading from unloading pipe 81. Quantitative blanking can be realized, and the working strength of workers is reduced. And the condition that the bottom end of the ash bucket 7 leaks due to excessive unloading because of excessive unloading can be avoided.

Furthermore, the two ends of the material baffle 82 are provided with connecting plates 85 extending into the limiting grooves 84, pull wires 86 are installed on the top surfaces of the connecting plates 85, the pull wires 86 extend upwards to extend into the inner wall of the discharging pipe 81 and are connected with the counterweight device 83 through fixed pulleys 87 installed in the discharging pipe 81, the outer wall of the discharging pipe 81 is further communicated with a discharging channel 88, and the discharging channel 88 and a communication port of the discharging pipe 81 are arranged on a moving path of the material baffle 82.

Meanwhile, the counterweight device 83 is arranged in a moving cavity 89 of the inner wall of the blanking pipe 81, the moving cavity 89 is arranged in parallel with the limiting groove 84, the counterweight device 83 comprises a weight block, and the top surface of the weight block is connected with the pull wire 86.

Furthermore, the striker plate 82 is obliquely arranged, the connecting plate 85 is arranged at the oblique end of the striker plate 82, and the connecting plate 85 is parallel to the striker plate 82.

Vertical baffles 810 are arranged on the upper surface and the lower surface of the connecting plate 85, the baffles 810 are used for separating the stay wire 86 from the inner pipe of the blanking pipe 81, one end, opposite to the connecting plate 85, of the baffle 810 vertically extends into a displacement channel 811 on the side wall of the blanking pipe 81, the displacement channel 811 is vertically arranged, and the displacement channel 811 is connected with the extending end of the baffle 810 through a compression spring 812.

Thus, the striker plate 82 is obliquely arranged, when the weight of the material above the striker plate 82 is greater than the weight of the weight, the striker plate 82 moves downwards, and the weight moves upwards through the pull wire 86, so that in the downward movement process of the striker plate 82, after the discharging channel 88 communicated with the discharging pipe 81 is communicated with the upper part of the striker plate 82, the material above the striker plate 82 can be discharged through the discharging channel 88, and simultaneously, along with the gradual reduction of the weight of the material above the striker plate 82, the striker plate 82 moves upwards gradually under the action of the weight, that is, the weight moves downwards, the striker plate 82 is lifted upwards to move upwards, so that the communicating state between the discharging channel 88 and the upper part of the striker plate 82 is broken, and the discharging is stopped, so that on the one hand, the discharging channel 88 is communicated with the bottom end side of the inclined end of the striker plate 82, so that the striker plate 82 can also play a guiding role in the discharging process, let unload more thoroughly, on the other hand lets striker plate 82 only reciprocate to avoid striker plate 82 in the in-process of rebound, because the jam of material causes the condition that unloading passageway 88 can't break off to appear.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
