DETAILED DESCRIPTION
[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.
[0028] like Figures 1 to 5 As shown, the dust collecting device for the coke intercepting car of the utility model comprises a dust collecting bucket 1, a connecting plate 2 connected to one side of the dust collecting bucket 1, a filter bucket 4 connected to the other side of the dust collecting bucket 1 through a first fan 3, and a butt joint pipe 6 connected to the connecting plate 2 through a second fan 5, wherein the butt joint pipe 6 is connected to the dust collecting pipe of the coke intercepting car at one end away from the second fan 5; a dust collecting mechanism 7 is arranged in the dust collecting bucket 1, and the dust collecting mechanism 7 comprises a fixing plate 71 sleeved on the inner wall of the connecting plate 2, a plurality of connecting heads 72 penetrating the fixing plate 71, and a dust collecting cloth bag 73 connected to the connecting head 72; a ventilation hole 41 is opened above the filter bucket 4, and a filtering mechanism 8 is arranged inside, and the filtering mechanism 8 comprises a partition plate 81, a plurality of connecting heads 72 penetrating the partition There are multiple docking joints 82 on the broken plate 81, and an exhaust ring 84 is provided on the outer circle of the docking joint 82. An exhaust hood 83 is provided above the docking joint 82. The exhaust hood 83 includes a top cover 831, an inner ring wall 832 and an outer ring wall 833 concentrically arranged below the top cover 831, a plurality of first exhaust holes 86 are opened above the inner ring wall 832, an exhaust groove 85 is opened below the outer ring wall 833, and a plurality of second exhaust holes 87 are opened on the exhaust groove 85. The docking joint 82 is arranged between the inner ring wall 832 and the outer ring wall 833, and the exhaust ring 84 is arranged in the exhaust groove 85. A water storage part 42 is arranged between the filter mechanism 8 and the ventilation hole 41, and the filter mechanism 8 is connected to the first fan 3 through the docking plate 43 below.
[0029] When the device stops operating, the top cover 831 in the filter mechanism 8 is subjected to the pressure exerted by the filtered water in the water storage section 42 and the gravity of the top cover 831 itself, and the bottom surface of the top cover 831 abuts against the top surface of the docking joint 82, and the inner upper surface of the exhaust groove 85 abuts against the upper surface of the exhaust ring 84. At this time, the first exhaust hole 86 is closed by the docking joint 82, and the second exhaust hole 87 is closed by the exhaust ring 84, and cannot be connected to the first exhaust hole 86.
[0030] As a specific embodiment, in the dust collecting device for the coke intercepting car of the utility model, a limiting groove 74 is provided on the connecting head 72, and a limiting ring 75 is provided at the opening of the dust collecting bag 73. The limiting groove 74 matches the limiting ring 75, and the limiting ring 75 is buckled in the limiting groove 74 and an elastic snap ring 76 is provided on the outer end. With such a configuration, when installing, it is only necessary to buckle the limiting ring 75 into the limiting groove 74. When removing, it is only necessary to directly remove the elastic snap ring 76, so that the disassembly and assembly between the dust collecting bag 73 and the connecting head 72 is more convenient, thereby greatly facilitating the replacement and cleaning of the dust collecting bag 73 after working for a period of time.
[0031] Furthermore, in the dust collecting device for the coke intercepting car of the utility model, the outer diameter of the inner ring wall 832 matches the inner diameter of the docking head 82, the distance between the inner ring wall 832 and the outer ring wall 833 is greater than the wall thickness of the docking head 82, the width of the exhaust ring 84 is less than the width of the exhaust groove 85, and the inner ring wall 832, the outer ring wall 833 and the docking head 82 are slidably connected. With such an arrangement, when the device starts to operate, with the operation of the second fan 5, the smoke and dust gas can be sucked into the dust collecting bag 73, and the dust collecting bag 73 can filter out the smoke and dust gas with larger particle size, and some of the smoke and dust gas with smaller particle size escapes from the surface gap of the dust collecting bag 73 into the dust collecting barrel 1, and with the operation of the first fan 3 The operation of the dust collecting bucket 1 draws the smoke and dust gas with smaller particle size in the dust collecting bucket 1 into the docking joint 82 in the filtering mechanism 8. At this time, the top cover 831 is squeezed upward by the smoke and dust gas, causing the top cover 831 to move upward, thereby driving the inner ring wall 832 and the outer ring wall 833 to move upward, so that the bottom surface of the top cover 831 is separated from the top surface of the docking joint 82, and the lower surface of the exhaust groove 85 abuts against the lower surface of the exhaust ring 84. At this time, the first exhaust hole 86 is connected to the docking joint 82 and the second exhaust hole 87 at the same time. The smoke and dust gas passes through the first exhaust hole 86 and the second exhaust hole 87 in turn and enters the water storage part 42. Then, the impurities in the smoke and dust gas are filtered out by the filtered water, and finally the purified gas is discharged from the ventilation hole 41.
[0032] More specifically, when the first fan 3 stops operating, the first exhaust hole 86 is not connected to the second exhaust hole 87, and the filtered water of the water storage section 42 cannot enter the gap between the inner annular wall 832 and the outer annular wall 833 through the second exhaust hole 87. When the first fan 3 is operating, the gap between the inner annular wall 832 and the outer annular wall 833, the first exhaust hole 86, and the second exhaust hole 87 are interconnected. Since the smoke gas flows into the filtered water of the water storage section 42 through the filter mechanism 8 in one direction, the filtered water still cannot enter the gap between the inner annular wall 832 and the outer annular wall 833 through the second exhaust hole 87, thereby achieving the unidirectional flow of the smoke gas. In addition, the exhaust ring 84 limits the axial position of the exhaust groove 85, so that the filter mechanism 8 can be automatically closed and connected according to the current working state.
[0033] As a specific implementation, in the dust collecting device for the coke intercepting car of the utility model, the docking plate 43 is connected to the first fan 3 through two sections of splicing tubes 9, and the first fan 3 is connected to the dust collecting barrel 1 through two sections of splicing tubes 9. The two sections of splicing tubes 9 are flange-connected. Of course, other connection methods such as an integrated connection can also be used, as long as the sealed transportation effect of the smoke gas is met.
[0034] As a specific implementation, in the dust collecting device for the coke intercepting car of the utility model, the connecting plate 2 is connected to the second fan 5 through two sections of spliced pipes, and the two sections of the spliced pipes and the spliced pipes and the connecting plate 2 are flange-connected. Of course, other connection methods such as an integrated connection can also be used as long as the sealed transportation effect of the smoke gas is met.
[0035] Furthermore, in the dust collection device for the coke intercepting car of the utility model, an observation window 11 is provided on the side of the dust collecting barrel 1, and the observation window 11 is inlaid with high-strength glass. Such a configuration allows the dust collection situation of the dust collecting bag 73 to be observed in real time during the operation of the device, making it convenient for the staff to replace and clean the dust collecting bag 73 in time.
[0036] Furthermore, in the dust collecting device for the coke intercepting car of the utility model, a plurality of first exhaust holes 86 are arranged at intervals along the inner annular wall 832 in the circumferential direction, and a plurality of second exhaust holes 87 are arranged at intervals along the exhaust groove 85 in the circumferential direction.
[0037] Furthermore, in the dust collecting device for the coke intercepting vehicle of the utility model, a plurality of connecting heads 72 are arranged at intervals along the circumferential direction of the fixing plate 71 .
[0038] The dust collecting principle of the dust collecting device for the coke intercepting car of the utility model is as follows: after starting the first fan 3 and the second fan 5, the smoke gas enters the docking pipe 6 from the dust collecting pipe of the coke intercepting car, passes through the second fan 5, and enters the dust collecting bag 73 through the connecting plate 2 and the connecting head 72. A large amount of dust in the smoke gas can be collected by the dust collecting bag 73 to complete a primary filtration, wherein a small amount of dust enters the internal space of the dust collecting barrel 1 along with the smoke, and the smoke gas is sucked into the filter mechanism 8 in the filter barrel 4 by the first fan 3, and is discharged from the ventilation hole 41 after secondary filtration by the filter mechanism 8, thereby completing the dust collection of the coke intercepting car.
[0039] In summary, compared with the prior art, the dust collecting device for the coke intercepting vehicle of the utility model has the following advantages and beneficial effects:
[0040] (1) The device realizes the unidirectional flow of smoke and dust gas through the cooperation between the inner annular wall 832, the outer annular wall 833 and the docking joint 82, as well as the gravity of the top cover 831 and the pressure of the filtered water in the water storage part 42, and prevents the filtered water in the water storage part 42 from flowing back to the docking joint 82, so that the filter mechanism 8 can be automatically closed and connected according to the current working status. The overall structure is simple and practical, and it is easy to disassemble and assemble.
[0041] (2) The device filters out a large amount of smoke gas with larger particle sizes through the dust collecting bag 73, and purifies the remaining smoke gas with smaller particle sizes through the cooperation of the filtering mechanism 8 and the water storage part 42, thereby realizing secondary filtration of the smoke gas of the coke intercepting car, greatly improving the filtering effect. The device has a compact structure, airtightness and purification functions, and prevents the leakage of smoke gas during the dust collection process from polluting the environment.
