[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model:
[0022] The fan 21, pneumatic butterfly valve 27 and motor 33 used in this application are products that can be directly purchased on the market, and their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here.
[0023] A dust removal device for the top of a bin in a mixing plant, comprising a bin body. The bin body includes an aggregate bin 1. The top end of the aggregate bin 1 is fixedly connected with an aggregate inlet interface 11. The surface of the aggregate inlet interface 11 is provided with a rotary feeder 12. The top end of the rotary feeder 12 is provided with a guiding hopper 13. One side of the guiding hopper 13 is provided with an aggregate conveyor belt 14. Through the arrangement of the aggregate conveyor belt 14, aggregates can enter the guiding hopper 13. Under the action of the guiding hopper 13 and the rotary feeder 12, the aggregates will enter the aggregate inlet interface 11, and then can enter the specified aggregate bin 1 through the aggregate inlet interface 11, thereby completing the feeding of the aggregates;
[0024] A dust removal mechanism is provided at the top of the aggregate bin 1. The dust removal mechanism includes a pulse dust collector 2. The pulse dust collector 2 is fixedly installed at the top of the aggregate bin 1. A fan 21 is installed at the top of the pulse dust collector 2. An air outlet pipe 22 is fixedly connected to the surface of the fan 21. A dust removal elbow 23 is fixedly connected to the surface of the pulse dust collector 2. A first dust removal pipe 24 is fixedly connected to the surface of the dust removal elbow 23. A second dust removal pipe 25 is fixedly connected to the surface of the guide hopper 13. An aggregate connection pipe 26 is fixedly connected to the surface of the aggregate inlet interface 11. A pneumatic butterfly valve 27 is fixedly installed on the surface of the aggregate connection pipe 26. The guide hopper 13 is designed in a double-layer form with a round bottom and a square top. The diameter of the round bottom is slightly larger than that of the rotary feeder 12, so that the rotary feeder 12 can rotate within the circle, achieving a sealing effect.
[0025] Further, one end of the first dust removal pipe 24 is fixedly connected to the guide hopper 13, and the other end of the first dust removal pipe 24 is fixedly connected to the end of the dust removal elbow 23 far from the pulse dust collector 2. By connecting the guide hopper 13 and the dust removal elbow 23 through the first dust removal pipe 24, the dust sucked out by the second dust removal pipe 25 can be sucked into the first dust removal pipe 24 and enter the pulse dust collector 2 for dust removal.
[0026] Further, one end of the second dust removal pipe 25 is fixedly connected to the guide hopper 13, and the other end of the second dust removal pipe 25 is fixedly connected to the end of the aggregate connection pipe 26 far from the aggregate inlet interface 11. By connecting the guide hopper 13 and the aggregate inlet interface 11 through the second dust removal pipe 25, when the aggregate enters the specified aggregate bin 1, the specified second dust removal pipe 25 works, achieving the dust removal effect during the feeding process.
[0027] Further, an ash discharging mechanism is provided on the surface of the pulse dust collector 2. The ash discharging mechanism includes a support plate 3. The support plate 3 is fixedly connected to the surface of the pulse dust collector 2. A rotating rod 31 is movably connected to the inner side of the support plate 3. A cam 32 is fixedly connected to the top of the rotating rod 31. A motor 33 is fixedly installed at the bottom of the support plate 3. Through the setting of the cam 32, when the rotating rod 31 rotates, the cam 32 rotates accordingly to knock on the pulse dust collector 2, and the vibration generated by the knocking can accelerate the falling of the dust, thus facilitating the better discharge of the dust.
[0028] Further, two groups of support plates 3 are fixedly connected to the pulse dust collector 2, and two groups of rotating rods 31 are correspondingly connected to the support plates 3. Through the setting of the rotating rods 31, when the rotating rods 31 rotate under the action of the support plates 3, the cams 32 can knock on the pulse dust collector 2 during rotation.
[0029] Further, the cam 32 is provided in two groups and is correspondingly connected to the rotating rod 31. One end of the rotating rod 31 away from the cam 32 is fixedly connected to the output end of the motor 33. By the operation of the motor 33, the rotating rod 31 can be driven to rotate. Further, the cam 32 can rotate accordingly under the action of the rotating rod 31 and can strike the surface of the pulse dust collector 2, so that when the pulse dust collector 2 is back blown and cleaned, the dust can fall better.
[0030] Working principle: In use, the fan 21 is electrically connected to an external power source. The staff starts the fan 21 by pressing the switch. The first dust collection pipe 24 will suck dust under the action of the fan 21. The pneumatic butterfly valve 27 is electrically connected to an external power source. The staff starts the pneumatic butterfly valve 27 by pressing the switch. The operation of the pneumatic butterfly valve 27 causes the corresponding second dust collection pipe 25 to open. When the aggregate enters the bin, the second dust collection pipe 25 can adsorb the dust during the bin entry, and then the dust can enter the pulse dust collector 2 for dust removal under the action of the first dust collection pipe 24, achieving the effect of dust removal during the bin entry.
[0031] The motor 33 is electrically connected to an external power source. The staff starts the motor 33 by pressing the switch. The operation of the motor 33 drives the rotating rod 31 to rotate. The cam 32 will rotate accordingly under the action of the rotating rod 31. When the convex surface of the cam 32 gradually contacts the surface of the pulse dust collector 2 during rotation, it will cause extrusion and knocking on the pulse dust collector 2. Further, the pulse dust collector 2 vibrates, so that when the pulse dust collector 2 is back blown and cleaned, the vibration can accelerate the falling of the dust, avoiding the adhesion and accumulation of the dust on the inner wall of the ash hopper at the bottom of the pulse dust collector 2, thereby improving the quality and efficiency of the dust cleaning. By the operation of the motor 33, the rotating rod 31 drives the cam 32 to rotate forward and backward, and the cam 32 can continuously strike the pulse dust collector 2.
[0032] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Any ordinary technician in the industry can smoothly implement the present invention according to the description in the attached drawings and the above content. However, any slight changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present invention by using the above disclosed technical content are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and variations made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
