Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a bag-type dust collector for collecting tailings in the preparation of zinc oxide. Background Technology

[0002] In modern chemical industry, zinc oxide is an important inorganic chemical raw material, widely used in rubber, coatings, electronics and other fields. During the production of zinc oxide, a large amount of dust gas containing zinc oxide tailings is generated. If it is not effectively collected and treated, it will not only waste zinc oxide tailings, but also cause serious environmental pollution and endanger the health of operators.

[0003] Existing baghouse dust collectors on the market have difficulty completely removing zinc oxide tailings adhering to the surface of the filter bags when used for collecting zinc oxide tailings. As the usage time increases, the filter bags are prone to clogging, which leads to a decrease in the filtration efficiency of the dust collector and thus affects the tailings collection effect. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: when bag filters are used for collecting zinc oxide tailings, it is difficult to completely remove the zinc oxide tailings adhering to the surface of the filter bags. As the usage time increases, the filter bags are prone to clogging, which leads to a decrease in the filtration efficiency of the dust collector and thus affects the tailings collection effect. Therefore, this invention proposes a bag filter for collecting zinc oxide tailings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A baghouse dust collector for collecting tailings in the preparation of zinc oxide includes a dust collection box, an installation plate installed inside the dust collection box, and a plurality of installation holes equally spaced on the installation plate. Each of the plurality of installation holes is fitted with a baghouse dust collection component through an installation assembly.

[0007] The dust collector box is fixedly mounted with a cover plate at its upper end by bolts. Multiple movable holes are equidistantly opened on the cover plate, and pulse jet pipes are vertically slidably installed in each of the movable holes. Pulse jet heads are fixedly installed at the lower ends of each pulse jet pipe, and each pulse jet head is positioned directly above multiple bag filter dust collection components. A flow divider plate is fixedly installed at the upper end of each pulse jet pipe, and a cavity is opened inside the flow divider plate. One end of each pulse jet pipe is connected to the cavity. A pulse pneumatic conveyor is fixedly installed on the upper surface of the flow divider plate, and the output end of the pulse pneumatic conveyor is connected to the cavity via a connecting pipe. A lifting assembly is provided on the side of the dust collector box to move the flow divider plate up and down.

[0008] Preferably, the lifting assembly includes a mounting bracket fixedly mounted on the dust collection box, a reciprocating screw vertically rotatably mounted on the mounting bracket, a drive motor fixedly mounted on the mounting bracket, and a lifting block threaded onto the reciprocating screw. The lifting block is fixedly connected to the diverter plate, and the output end of the drive motor is fixedly connected to the upper end of the reciprocating screw.

[0009] Preferably, the lifting block is rectangular, and the side of the lifting block slides in contact with the side of the mounting frame.

[0010] Preferably, the bag filter assembly includes a filter bag frame and a filter bag body. The filter bag frame has a cylindrical structure and a plurality of ventilation holes are evenly distributed on the surface of the filter bag frame. The filter bag body is fitted over the filter bag frame.

[0011] Preferably, the mounting assembly includes an upper connecting plate and a lower connecting plate that are fixedly mounted on the upper and lower ends of the filter bag frame, respectively. The upper end of the filter bag body is sealed to the upper connecting plate, and the lower end of the filter bag body is sealed to the lower connecting plate. The upper connecting plate is mounted on a mounting plate.

[0012] Preferably, the axis of the pulse jet pipe coincides with the axis of the filter bag frame, and the length of the pulse jet pipe is less than the length of the filter bag frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. A stable pulse airflow is provided by a pulse pneumatic conveyor. Combined with the cooperation of the diverter plate and the pulse jet pipe, high-pressure gas can be sprayed from the pulse jet head. The compressed air can directly act on the bag filter dust collector, which can directly shake off the zinc oxide tail material attached to the surface of the bag filter dust collector, realize the cleaning of the filter bag, and prevent the filter bag from clogging.

[0015] 2. The pulse jet nozzle can spray up and down repeatedly directly above the filter bag body, which can comprehensively impact the zinc oxide tailings adhering to different heights on the filter bag surface, effectively avoiding the problem of local tailings residue caused by the limited spray range, and significantly improving the thoroughness of tailings removal.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-2 A baghouse dust collector for collecting tailings in zinc oxide production includes a dust collection box 1. An mounting plate 2 is installed inside the dust collection box 1. Multiple mounting holes are evenly spaced on the mounting plate 2. Baghouse dust collection components are installed in each of these mounting holes via mounting assemblies. Each baghouse dust collection component includes a filter bag frame 12 and a filter bag body 13. The filter bag frame 12 is cylindrical, and its surface has multiple evenly distributed ventilation holes. The filter bag body 13 is fitted over the filter bag frame 12. The mounting assembly includes an upper connecting plate 14 and a lower connecting plate 15, respectively fixedly installed at the upper and lower ends of the filter bag frame 12. The upper end of the filter bag body 13 is sealed to the upper connecting plate 14, and the lower end of the filter bag body 13 is sealed to the lower connecting plate 15. The upper connecting plate 14 is mounted on the mounting plate 2. (Refer to...) Figure 4 .

[0024] Dust collection box 1 provides a closed dust collection space for the entire dust collector, preventing leakage of dust gas containing zinc oxide tailings. Mounting plate 2 provides a stable mounting base for the bag filter assembly through mounting holes and mounting components, ensuring the bag filter assembly is fixed in position during dust collection. The cylindrical structure and surface ventilation holes of the filter bag frame 12 not only support the filter bag body 13 in its unfolded state but also allow the filtered gas to be smoothly discharged through the ventilation holes. As the core filtration component, the filter bag body 13 can intercept zinc oxide tailings in the dust gas, achieving gas-solid separation. The upper connecting plate 14 and the lower connecting plate 15 are respectively sealed to the upper and lower ends of the filter bag body 13, preventing unfiltered dust gas from bypassing the filtration structure through the gap between the filter bag body 13 and the filter bag frame 12. At the same time, the cooperation between the upper connecting plate 14 and the mounting plate 2 allows for quick assembly and disassembly of the bag filter assembly, facilitating later maintenance and replacement.

[0025] Reference Figure 3 and Figure 5 The upper end of the dust collector 1 is fixedly installed with a cover plate 3 by bolt fasteners. Multiple movable holes are equally spaced on the cover plate 3. Pulse jet pipes 4 are vertically slidably installed in each of the multiple movable holes. Pulse jet heads 5 are fixedly installed at the lower ends of the multiple pulse jet pipes 4. The multiple pulse jet heads 5 are respectively located directly above multiple bag dust collector components. The cover plate 3 is fixed to the dust collector 1 by bolt fasteners and can be opened to allow for maintenance of the internal components of the dust collector 1. The movable holes provide a vertical sliding guide path for the pulse jet pipes 4 to prevent the pulse jet pipes 4 from shifting during movement.

[0026] A flow divider plate 6 is fixedly installed on the upper end of multiple pulse jet pipes 4. A cavity is opened inside the flow divider plate 6. One end of each of the multiple pulse jet pipes 4 is connected to the cavity. A pulse pneumatic conveyor 7 is fixedly installed on the upper surface of the flow divider plate 6. The output end of the pulse pneumatic conveyor 7 is connected to the cavity through a connecting pipe. A lifting component for driving the flow divider plate 6 to move up and down is provided on the side of the dust collector box 1.

[0027] The pulse pneumatic conveyor 7 serves as the airflow power source, generating high-pressure pulsed airflow during operation. This airflow is then transported through the connecting pipe to the cavity of the diverter plate 6. The cavity acts as a buffer and diverter for the airflow, evenly distributing the high-pressure pulsed airflow to multiple pulse jet pipes 4. The high-pressure pulsed airflow is then transmitted through the pulse jet pipes 4 to the pulse jet head 5, and finally ejected by the pulse jet head 5, acting on the filter bag body 13. The airflow impact shakes off the zinc oxide tailings adhering to the surface of the filter bag body 13, achieving filter bag cleaning and preventing filter bag blockage.

[0028] The lifting assembly includes a mounting bracket 8 fixedly mounted on the dust collection box 1, a reciprocating screw 9 vertically rotatably mounted on the mounting bracket 8, a drive motor 10 fixedly mounted on the mounting bracket 8, and a lifting block 11 threaded onto the reciprocating screw 9. The lifting block 11 is fixedly connected to the diverter plate 6, and the output end of the drive motor 10 is fixedly connected to the upper end of the reciprocating screw 9. The lifting block 11 is rectangular, and the side of the lifting block 11 slides in contact with the side of the mounting bracket 8. The mounting bracket 8 limits the lifting block 11 to prevent it from rotating synchronously with the reciprocating screw 9.

[0029] Mounting bracket 8 provides mounting support for reciprocating screw 9, drive motor 10 and lifting block 11, ensuring the overall structural stability of the lifting assembly. When the drive motor 10 is working, it outputs torque to drive the reciprocating screw 9 to rotate vertically on mounting bracket 8. The rotation of the reciprocating screw 9 is converted into the vertical reciprocating motion of the lifting block 11. The lifting block 11 is fixedly connected to the diversion plate 6, which can drive the diversion plate 6 and the pulse jet pipe 4 and pulse jet head 5 connected to it to move up and down synchronously, so that the pulse jet head 5 can spray the filter bag body 13 at different height positions, avoiding the local residual zinc oxide tail material in the filter bag body 13 due to the limited spray range, and further improving the thoroughness of dust removal.

[0030] The axis of the pulse jet pipe 4 coincides with the axis of the filter bag frame 12. The length of the pulse jet pipe 4 is less than the length of the filter bag frame 12. The coincidence of the axis of the pulse jet pipe 4 and the axis of the filter bag frame 12 ensures that the high-pressure airflow ejected by the pulse jet head 5 is accurately directed above the filter bag body 13. Furthermore, the length of the pulse jet pipe 4 is less than the length of the filter bag frame 12, which prevents the pulse jet pipe 4 from colliding with the filter bag frame 12 or the filter bag body 13 during descent, thus protecting the filter bag structure from damage.

[0031] In this invention, dusty gas containing zinc oxide tailings enters the dust collector 1. The filter bag body 13 filters the dusty gas, and the zinc oxide tailings adhere to the surface of the filter bag body 13. The filtered gas is discharged through the ventilation holes of the filter bag frame 12. When a lot of tailings are attached to the surface of the filter bag body 13, the pulse pneumatic conveyor 7 and the drive motor 10 are started. The high-pressure pulse airflow generated by the pulse pneumatic conveyor 7 is ejected from the pulse jet head 5 through the diverter plate 6 and the pulse jet pipe 4. At the same time, the drive motor 10 drives the diverter plate 6 and the pulse jet head 5 to move up and down through the reciprocating screw 9 and the lifting block 11, so as to spray and clean the filter bag body 13 throughout its entire height range. The shaken-off zinc oxide tailings are collected at the bottom of the dust collector 1, realizing the cleaning of the filter bag and preventing the filter bag from clogging.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
