[0026] An inclined zipper pit dust collection device, comprising a grate cooler 1, a clinker pit 2, an inclined zipper body 3, a fan 4 and bolts 10. An air duct 5 passing through the housing of the grate cooler 1 is fixedly connected to the air inlet of the fan 4. One end of the air duct 5 away from the fan 4 is communicated with a parallel dust collection duct 6 through a flange. One end of the parallel dust collection duct 6 away from the air duct 5 is communicated with a discharge pipe 7 through a flange. A dust collection hood 8 is fixedly connected to the outside of the discharge pipe 7. A first screw hole 9 is opened on the outside of the dust collection hood 8. Mounting blocks 11 are symmetrically arranged on the outside of the dust collection hood 8. A second screw hole 12 is opened on the inner side of the mounting block 11. A clamping groove 13 is opened on the side of the mounting block 11 close to the dust collection hood 8. A damping pad 14 is snap-fitted in the inner side of the clamping groove 13. A positioning block 15 is fixedly connected to the inner side of the damping pad 14. A V-shaped air duct 16 is fixedly connected to the inner side of the positioning block 15. A return passage 17 is arranged at the bottom of the grate cooler 1.
[0027] The sectional circle radius of the first screw hole 9 is equal to that of the second screw hole 12. The mounting block 11 is detachably connected to the dust collection hood 8 by a bolt 10 passing through the first screw hole 9 and the second screw hole 12. This setting enables the mounting block 11 to be connected to the dust collection hood 8 by successively passing the bolt 10 through the first screw hole 9 and the second screw hole 12. Then, the damping pad 14 and the positioning block 15 are engaged together inside the card slot 13. The damping pad 14 enhances the friction between the positioning block 15 and the inner wall of the card slot 13, enabling stable installation of the positioning block 15, that is, the V-shaped air duct 16 is installed at the bottom of the dust collection hood 8 through the positioning block 15 and the mounting block 11; the discharge pipe 7 is communicated with the dust collection hood 8, the dust collection hood 8 is communicated with the V-shaped air duct 16, and the return passage 17 is communicated with the housing of the grate cooler 1. This setting enables dust to enter the dust collection hood 8 through the V-shaped air duct 16, and then enter the discharge pipe 7 from the dust collection hood 8. Under the action of the fan 4, the dust will enter the parallel dust collection pipeline 6 and the air duct 5 from the discharge pipe 7, and finally enter the grate cooler 1; several V-shaped air ducts 16 are evenly arranged, the V-shaped air duct 16 penetrates through the damping pad 14, and the V-shaped air duct 16 is arranged at the top of the inclined zipper body 3. This setting enables the V-shaped design of the V-shaped air duct 16 to help guide the air flow to flow in a predetermined direction, reduce vortex and turbulent flow phenomena, and at the same time enhance the air flow velocity: when the total air volume remains unchanged, due to the reduction of the outlet cross-sectional area, the V-shaped air duct 16 can form a higher air flow velocity at the outlet; the grate cooler 1 is installed on the top of the clinker pit 2, the inclined zipper body 3 is installed inside the clinker pit 2, and the fans 4 are evenly arranged and installed inside the grate cooler 1. This setting enables the positioning of the grate cooler 1, the clinker pit 2, the inclined zipper body 3 and the fans 4, so as to be used in cooperation.
[0028] Workflow: All electrical appliances in the present utility model are provided with an external power supply or a built-in battery. The parallel dust collection pipeline 6 is connected to the air inlet of the No. 25 fan 4 inside the grate cooler 1 through an air duct 5. The mounting block 11 is connected to the dust collection hood 8 by sequentially passing through the first screw hole 9 and the second screw hole 12 with bolts 10. Then, the damping pad 14 and the positioning block 15 are engaged inside the card slot 13 together. The damping pad 14 enhances the friction between the positioning block 15 and the inner wall of the card slot 13, enabling stable installation of the positioning block 15. That is, the V-shaped air duct 16 is installed at the bottom of the dust collection hood 8 through the positioning block 15 and the mounting block 11. Start the fan 4 inside the grate cooler 1 connected to the air duct 5, so that the dust generated by the inclined zipper body 3 during product transportation in the clinker pit 2 can enter the dust collection hood 8 through the V-shaped air duct 16, and then enter the discharge pipe 7 from the dust collection hood 8. Under the action of the fan 4, the dust will enter the parallel dust collection pipeline 6 and the air duct 5 from the discharge pipe 7, and finally enter the grate cooler 1. The dust is blown into the grate cooler 1 to settle, and then returns to the inclined zipper body 3 through the return channel 17. The No. 25 fan 4 of the grate cooler 1 is used as a separate centrifugal cooling air conditioner for the parallel dust collection pipeline 6, and the required power is completely provided by the negative pressure of the No. 25 fan 4 of the grate cooler 1. Since the No. 25 fan 4 of the grate cooler 1 is the last cooling fan 4 in the third stage of the grate cooler 1, there is no problem of increasing power consumption here, and it circulates infinitely, achieving the purpose of safety, energy conservation and environmental protection, improving the clinker production capacity, and increasing the sales profit. The V-shaped design of the V-shaped air duct 16 helps to guide the air flow to flow in a predetermined direction, reducing eddy current and turbulent flow phenomena, and at the same time can enhance the air flow velocity: when the total air volume remains unchanged, due to the reduction of the outlet cross-sectional area, the V-shaped air duct 16 can form a higher air flow velocity at the outlet.
