Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, in particular to a fine dust collecting device for producing gangue ceramsite. Background Art

[0002] A certain amount of dust may be generated during the production of gangue ceramsite. In order to ensure the cleanliness of the production environment and meet environmental protection requirements, bag dust collectors play an important role. Bag dust collectors can effectively filter out the dust generated during the production of gangue ceramsite, reduce environmental pollution, and improve production efficiency.

[0003] The working principle of the bag filter dust collector mainly includes: the dust generated during the production of coal gangue ceramsite enters the dust collector and enters the filter chamber after pretreatment. In the filter chamber, a large number of filter bags will capture the dust and deposit it on the filter bags. The clean air passes through the filter bags and enters the exhaust duct, and finally exits the dust collector. When the dust on the filter bag accumulates to a certain extent, it needs to be cleaned to ensure the continuous and efficient operation of the dust collector;

[0004] After a certain period of use, the bag filter needs to remove the dust on the bag. The pulse backflush can directly remove the dust from the bag inside the dust collector. A large amount of dust is removed and falls into the ash hopper. A valve is provided at the bottom of the ash hopper. The accumulated dust is collected by opening the valve. However, during the cleaning process, if the operation is improper or the cleaning method is unreasonable, it is easy to cause secondary dust flying, causing pollution to the environment, and the opening of the cleaning valve will also affect the normal operation of the dust collector.

[0005] In order to solve the above problems, the present application proposes a fine dust collection device for producing coal gangue ceramsite. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] See also Figure 1-7 As shown, the utility model is a fine dust collection device for producing coal gangue ceramsite, comprising a dust removal box 1, a dust collecting hopper 2 is fixed at the bottom of the dust removal box 1, a partition chamber 3 is connected to the bottom of the ash collecting hopper 2, a ash dropping hopper 4 is connected to the bottom of the partition chamber 3, a telescopic bellows 5 is connected to the bottom of the ash dropping hopper 4, a docking seat 6 is connected to the bottom of the telescopic bellows 5, and the docking seat 6 can also be vertically movable through the telescopic bellows 5, including a dust cleaning bucket 7 located below the docking seat 6, a vertically movable upper sealing block 8 is provided inside the ash collecting hopper 2, a vertically movable lower sealing block 9 is provided between the partition chamber 3 and the ash dropping hopper 4, an internal threaded rod 10 is fixed to the lower sealing block 9, and a driving component that can drive the upper sealing block 8, the lower sealing block 9 and the docking seat 6 to move vertically is also provided on the partition chamber 3, and the driving component can simultaneously drive the upper sealing block 8, the lower sealing block 9 and the docking seat 6 to rise and the lower sealing block 9 and the docking seat 6 to descend independently.

[0033] Among them, the outer part of the internal threaded rod 10 is rectangular and slides through the upper sealing block 8. A spring 11 is arranged between the upper sealing block 8 and the lower sealing block 9. A dust cover 12 located outside the spring 11 is also arranged between the lower end of the upper sealing block 8 and the upper end of the lower sealing block 9. In this embodiment, the spring 11 ensures the fit between the upper sealing block 8 and the ash hopper 2 during the independent lifting of the lower sealing block 9. The arranged spring 11 and dust cover 12 not only prevent dust but also play a stabilizing role, thereby ensuring the reliable fit between the upper sealing block 8 and the lower sealing block 9.

[0034] Among them, the driving component includes a mounting frame 14 fixed on the inner side of the ash hopper 4 and a screw 15 rotating on the mounting frame 14, and a motor 16 fixed on the outer side of the ash hopper 4 and connected to the screw 15 through a bevel gear pair. The screw 15 is provided with threads on the upper and lower ends. In this embodiment, the output shaft of the motor 16 is horizontally installed, and the screw 15 is vertically installed. The two are driven by a bevel gear pair. The screw 15 is simultaneously located in the partition chamber 3, the ash hopper 4, the telescopic bellows 5, and the docking seat 6.

[0035] Among them, the upper end thread of the screw 15 is spirally connected to the internal threaded rod 10. In this embodiment, the upper sealing block 8 and the lower sealing block 9 are driven to rise and fall by the spiral. The part of the internal threaded rod 10 that passes through and slides in the upper sealing block 8 is a rectangular structure, which prevents the upper sealing block 8 from rotating after being lifted, thereby ensuring the structural stability.

[0036] Among them, an internal threaded sleeve 13 is fixedly provided on the inner side of the docking seat 6, and the internal threaded sleeve 13 cooperates with the lower end thread of the screw 15. The thread directions of the two ends of the screw 15 are consistent with the internal threaded rod 10 and the internal threaded sleeve 13, but the pitch of the lower end of the screw 15 is smaller than the pitch of the upper end. In this embodiment, the lifting and lowering of the docking seat 6 is achieved by the spiral of the internal threaded sleeve 13 and the screw 15. When the docking seat 6 rises, the telescopic bellows 5 can provide sufficient space for movement, and after descending, it can fit tightly with the ash cleaning bucket 7 to ensure the sealing of the ash falling channel and avoid a large amount of dust in the ash falling process. The consistent thread direction can make the docking seat 6 fit tightly with the ash cleaning bucket 7 while the lower sealing block 9 descends to fall ash, so as to realize the opening of the ash falling and the sealing of the overall ash falling channel.

[0037] Among them, the upper end of the ash cleaning bucket 7 is open, and a horizontally slidable sealing plate 17 is provided at the inner upper end of the ash cleaning bucket 7. In this embodiment, the opening at the upper end of the ash cleaning bucket 7 is closed or opened by sliding the sealing plate 17 to prevent dust inside the ash cleaning bucket 7 from being raised after the docking seat 6 is detached.

[0038] Among them, the upper and lower ends of the upper sealing block 8 and the upper end of the lower sealing block 9 are all conical structures. In this embodiment, the cone of the lower end of the upper sealing block 8 is consistent with the inner bottom of the ash hopper 2. After contact, the sealing between the ash hopper 2 and the partition chamber 3 is guaranteed. The cones at the upper ends of the upper sealing block 8 and the lower sealing block 9 are used to avoid the accumulation of dust at their upper ends, so that the dust can be removed more thoroughly.

[0039] It can be understood that, first of all, the partition chamber 3 set up can store dust independently, and when cleaning is needed, the dust inside the ash hopper 2 can be transferred to the partition chamber 3. At this time, the partition chamber 3 can be cleaned in the sealed state of the ash hopper 2 without shutting down the dust collector, thereby improving efficiency. Secondly, a vertically movable docking seat 6 is provided to cooperate with the ash cleaning bucket 7 to form a sealed channel during the cleaning process to prevent dust from overflowing and generating dust during the process of being collected in the ash cleaning bucket 7. Finally, the lead screw 15 set up can control the dust inside the ash hopper 2 to enter the partition chamber 3, the dust inside the partition chamber 3 to fall, and the docking seat 6 and the ash cleaning bucket 7 to dock, which has the advantages of high structural coordination and linkage.

[0040] A specific application of this embodiment is: Figure 4 In the state shown, the dust collecting hopper 2 is in a closed state, and the dust filtered by the bag inside the dust removal box 1 falls into the dust collecting hopper 2 above the upper sealing block 8, as shown in FIG. Figure 5 As shown, the motor 16 drives the lead screw 15 to rotate through the bevel gear pair, and the lead screw 15 drives the upper sealing block 8 and the lower sealing block 9 to move vertically upward through the spiral with the internal threaded rod 10, and the lower sealing block 9 slides inside the partition chamber 3, and the upper sealing block 8 is separated from the contact with the ash collecting hopper 2. At this time, the ash collecting hopper 2 and the partition chamber 3 are interconnected, and the dust inside the ash collecting hopper 2 enters the partition chamber 3. When the lead screw 15 rotates, it will also generate a spiral with the internal threaded sleeve 13, and the spiral will drive the docking seat 6 to move upward. At this time, the telescopic bellows 5 contracts and drives the motor 16 in the reverse direction. Figure 5 Restore to the attached Figure 4 In the state shown, the dust in the ash collecting hopper 2 is collected in the partition chamber 3;

[0041] like Figure 6 As shown, place the ash cleaning bucket 7 just below the docking seat 6, open the sealing plate 17, and drive the motor 16 and the lead screw 15 to drive the lower sealing block 9 and the internal threaded rod 10 to move downward. Since the upper sealing block 8 is already in contact with the inner bottom of the ash collecting hopper 2, the upper sealing block 8 cannot move. At this time, the spring 11 will be stretched, and the two dust cover 12 will extend out to each other. At this time, the docking seat 6 is tightly fitted with the top of the ash cleaning bucket 7 under the spiral of the lead screw 15 and the internal threaded sleeve 13. The lower sealing block 9 is located inside the ash dropping hopper 4, and the dust enters the ash cleaning bucket 7 from the inside of the partition chamber 3 through the telescopic bellows 5 and the docking seat 6. After the collection is completed, the sealing plate 17 is closed first, and then the motor 16 is driven in the reverse direction to reset the lower sealing block 9 and the ash cleaning bucket 7 upward to Figure 4 state.
