Description

Technical Field

[0001] This utility model relates to the field of zinc oxide production technology, and in particular to a furnace ash filtration and recovery structure for zinc oxide production. Background Technology

[0002] The production of zinc oxide generates a large amount of furnace ash, which contains unreacted raw materials, zinc oxide, and other impurities. If not effectively recycled, this wastes resources, as the zinc oxide and some raw materials in the ash can be reused. Furthermore, indiscriminate disposal of ash pollutes the environment; for example, heavy metals may seep into soil and water, posing environmental risks. Traditional ash treatment methods often involve simple collection and stockpiling, or coarse filtration methods with low efficiency, failing to effectively separate useful components and impurities of different particle sizes. With increasingly stringent environmental requirements and greater emphasis on resource recycling by enterprises, there is an urgent need for a highly efficient and precise ash filtration and recycling structure to meet the ash treatment needs of zinc oxide production. Therefore, we are introducing a new ash filtration and recycling structure for zinc oxide production. Utility Model Content

[0003] The main objective of this invention is to provide a furnace ash filtration and recovery structure for zinc oxide production, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A zinc oxide production furnace ash filtration and recovery structure includes a box door, a collection device mounted on the rear end of the box door via a hinge, support feet fixedly connected to the four lower corners of the collection device, a box cover mounted on the upper rear part of the collection device via a hinge, handles fixedly connected to the upper left and upper right parts of the box cover, a feed pipe fixedly connected to the upper middle part of the box cover, a side plate fixedly connected to the upper right part of the collection device, a main body device fixedly connected to the lower right part of the side plate, and an observation round window fixedly connected to the front middle part of the box door.

[0006] The main device includes a drive motor and a belt. The output end of the drive motor passes through the side plate and is fixedly connected to a main pulley. The main pulley is connected to a driven pulley via a belt drive. A fixed rod is fixedly connected to the upper right side of the driven pulley. A linkage plate is fixedly connected to the upper outer surface of the fixed rod. A filter assembly is fixedly connected to the other end of the linkage plate. The drive motor is fixedly connected to the lower right side of the side plate.

[0007] Preferably, the filter assembly includes a filter bucket, with several locking strips fixedly connected inside the filter bucket, a chuck box being snapped into the filter bucket, several filter screens fixedly connected to the outer surface of the chuck box, several slots formed on the outer surface of the chuck box, grooves formed on both the front and rear sides of the outer surface of the filter bucket, and pulley sliders fixedly connected to the front and rear groove walls of the two grooves, and the filter bucket being fixedly connected to the left end of the linkage plate.

[0008] By adopting the above technical solution, the cooperation between the clip and the slot allows the chuck box to be stably installed in the filter hopper, ensuring that the relative positions of the two are fixed during the filtration process. The filter screen can perform preliminary filtration on the incoming material and intercept larger particulate impurities. This snap-fit ​​structure facilitates the installation, disassembly and cleaning of the chuck box, and makes it easy to maintain or replace the filter screen. At the same time, it is also conducive to the coordinated work of the filter hopper and the chuck box, improving filtration efficiency.

[0009] Preferably, the collection device includes a recycling bin, with a movable groove on the upper right side of the recycling bin, sliding grooves on the upper front and rear walls of the recycling bin, a limiting groove between the middle of the left and right walls of the recycling bin, a screening screen plate slidably connected between the left and right walls of the recycling bin, a collection box placed on the lower wall of the recycling bin, and a hinge installed at the lower end of the bin cover.

[0010] By adopting the above technical solution: the screening screen can perform secondary screening on the material falling from the filter hopper, further removing impurities and improving the purity of the material; the sliding connection method facilitates the removal and cleaning of the screening screen; and the collection box is used to collect the material after two screenings for centralized processing.

[0011] Preferably, the positions and dimensions of the plurality of slots correspond one-to-one with the plurality of slot strips, the plurality of slot strips are arranged in a ring array with the filter bucket as the center, the outer surface of the filter bucket does not contact the inner wall of the recycling bin, the two pulley sliders are slidably connected in the slide groove, and the filter bucket has a conical structure.

[0012] By adopting the above technical solution, the conical structure helps the material to concentrate at the bottom during shaking, which facilitates the smooth flow of filtered material. At the same time, it also makes the distribution of material in the filter hopper more reasonable and improves the uniformity of filtration.

[0013] Preferably, the lower end of the pulley is movably connected to the left side of the lower plate wall of the side plate via a bearing, and the linkage plate is movably connected within the movable groove.

[0014] By adopting the above technical solution, the interlocking and movable connection of the linkage plate in the movable slot ensures that it has an accurate trajectory during movement, which can stably drive the filter bucket to reciprocate and ensure the smooth progress of the entire filtration process.

[0015] Preferably, the screening screen is located directly below the filter hopper, the collection box is located directly below the screening screen, and the mesh diameter of the screening screen is smaller than the mesh diameter of the filter screen.

[0016] By adopting the above technical solution, the smaller mesh diameter of the screening screen can further intercept small particulate impurities that remain after the first filtration, improve the purity of the material, and ultimately allow purer material to fall into the collection box.

[0017] Preferably, the chuck box is located directly below the feed pipe, and the chuck box and the filter hopper are detachably snapped together.

[0018] By adopting the above technical solution: the chuck box is located directly below the feed pipe and can accurately receive materials, ensuring that the materials are first filtered through the filter screen of the chuck box. The detachable snap-fit ​​structure makes it easy to remove the chuck box separately, and facilitates cleaning, maintenance or replacement of the chuck box and its filter screen.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In this utility model, the drive motor starts and drives the main pulley to rotate. The belt drive causes the secondary pulley to rotate, and the fixed rod on the pulley drives the linkage plate to reciprocate. The material enters the chuck box from the feed pipe, and after preliminary filtration by its filter screen, it enters the filter hopper. The chuck box and the filter hopper are engaged. The filter hopper slides in the slide groove through the pulley slider and shakes under the drive of the linkage plate for further filtration. This device provides power and a stable filtration structure for filtration, with stable transmission, high filtration accuracy, and a detachable design for easy maintenance, thus improving filtration efficiency.

[0021] 2. In this utility model, a recycling bin is provided to accommodate and coordinate the materials. A movable groove is provided for the movement of the linkage plate. A sliding groove cooperates with a pulley slider. A limiting groove limits the screening screen plate. The screening screen plate is located below the filter hopper for secondary screening. The mesh size is smaller than that of the filter screen. A collection box is located on the lower wall of the recycling bin to collect the materials after the two screenings. This device ensures the coordination and stable operation of each component. The secondary screening improves the purity of the materials. The collection box facilitates the collection of materials, thereby improving the efficiency and quality of furnace ash filtration and recovery. Attached Figure Description

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A zinc oxide production furnace ash filtration and recovery structure includes a box door 1. A collection device 8 is installed at the rear end of the box door 1 via a hinge. Support feet 3 are fixedly connected to the four corners of the lower end of the collection device 8. A box cover 4 is installed at the upper rear end of the collection device 8 via a hinge. A handle 6 is fixedly connected to the upper left and upper right ends of the box cover 4. A feed pipe 5 is inserted and fixedly connected to the upper middle of the upper end of the box cover 4. A side plate 9 is fixedly connected to the upper right end of the collection device 8. A main body device 7 is fixedly connected to the lower right end of the side plate 9. An observation round window 2 is fixedly connected to the front middle of the box door 1.

[0032] In this embodiment, the main device 7 includes a drive motor 71 and a belt 74. The output end of the drive motor 71 passes through the side plate 9 and is fixedly connected to a main pulley 72. The main pulley 72 is driven by a secondary pulley 73 via the belt 74. A fixing rod 75 is fixedly connected to the upper right side of the secondary pulley 73. A linkage plate 76 is fixedly connected to the upper part of the outer surface of the fixing rod 75. A filter assembly 77 is fixedly connected to the other end of the linkage plate 76. The drive motor 71 is fixedly connected to the lower right side of the side plate 9. The filter assembly 77 includes a filter bucket 771. Several locking strips 772 are fixedly connected inside the filter bucket 771. A chuck box 776 is snapped into the filter bucket 771. Several filter screens 778 are fixedly connected to the outer surface of the chuck box 776. Several slots 777 are opened on the outer surface of the chuck box 776. The outer surface of the filter 771 has grooves 774 on both the front and rear sides. The front and rear groove walls of the two grooves 774 are fixedly connected to pulley sliders 775. The filter hopper 771 is fixedly connected to the left end of the linkage plate 76. The position and size of several slots 777 correspond one-to-one with several clips 772. The clips 772 are arranged in a ring array with the filter hopper 771 as the center. The outer surface of the filter hopper 771 does not contact the inner wall of the recycling box 81. The two pulley sliders 775 are slidably connected in the slide groove 83. The filter hopper 771 has a conical structure and is movably connected to the lower left side of the side plate 9 through a bearing from the lower end of the pulley 73. The linkage plate 76 is movably connected in the movable groove 82. The chuck box 776 is located directly below the feed pipe 5. The chuck box 776 and the filter hopper 771 have a detachable snap-fit ​​structure.

[0033] Through the above scheme: After the drive motor 71 starts, its output end drives the main pulley 72 to rotate. The motor, as the power source, provides the initial power for the operation of the entire filtration and recovery structure. The main pulley 72 rotates under the drive motor 71, and through the connection of the belt 74 and the driven pulley 73, the power is transmitted to the driven pulley 73, causing the driven pulley 73 to rotate accordingly. The belt 74 transmission has the characteristics of smooth transmission and shock absorption, ensuring the stability of power transmission and effectively transmitting the power of the drive motor 71 to the driven pulley 73, realizing long-distance transmission, and can also provide overload protection to a certain extent, avoiding damage to the motor or other components due to overload. When the driven pulley 73 rotates, the fixed rod 75, which is fixedly connected to the upper right side of the driven pulley 73, moves in a circular motion with the driven pulley 73. The fixed rod 75 drives the linkage plate 76 to reciprocate in the movable groove 82. Since the fixed rod 75 is fixedly connected to the linkage plate 76, the circular motion is converted into linear reciprocating motion, realizing the conversion of motion form, providing power for the shaking of the filter bucket 771, enabling the filter bucket 771 to reciprocate in the horizontal direction, enhancing the filtering effect. For filtration, material enters the chuck box 776 located directly below the feed pipe 5. Several filter screens 778 on the outer surface of the chuck box 776 perform preliminary filtration of the material, intercepting larger particles of impurities. The chuck box 776 is engaged with the retaining strip 772 inside the filter bucket 771 via a retaining groove 777. This detachable engaging structure facilitates installation, disassembly, and cleaning. The filter bucket 771 has a conical structure, which helps the material to concentrate at the bottom during shaking. The filter bucket 771 moves in the recovery bin via pulleys and sliders 775 in the grooves 774 on its outer surface. The sliding mechanism within the groove 83 of 81 ensures the stable reciprocating motion of the filter bucket 771 driven by the linkage plate 76. Under the reciprocating motion of the linkage plate 76, the chuck box 776 and the filter bucket 771 shake as a whole, further filtering the material. The double-layer filtration structure of the filter screen 778 of the chuck box 776 and the filter bucket 771 effectively improves the filtration accuracy. The detachable design facilitates maintenance. The special structure and sliding connection of the filter bucket 771 ensure its stability and reliability during movement, extending the service life of the equipment and improving filtration efficiency.

[0034] In this embodiment, the collection device 8 includes a recycling bin 81. A movable groove 82 is opened on the upper right end of the recycling bin 81. Sliding grooves 83 are opened on the upper front and rear walls of the recycling bin 81. A limiting groove 84 is opened between the middle of the left and right walls of the recycling bin 81. A screening screen 86 is slidably connected between the left and right walls of the recycling bin 81. A collection box 85 is placed on the lower wall of the recycling bin 81. The recycling bin 81 is hinged to the lower end of the cover 4. The screening screen 86 is located directly below the filter hopper 771. The collection box 85 is located directly below the screening screen 86. The mesh diameter of the screening screen 86 is smaller than the mesh diameter of the filter screen 778.

[0035] Through the above scheme: the recycling bin 81 provides space for the entire filtration and recycling process; the movable groove 82 at its upper right end provides a channel for the movement of the linkage plate 76; the sliding grooves 83 on the upper parts of the front and rear bin walls cooperate with the pulley sliders 775 of the filter hopper 771; the limiting groove 84 between the middle parts of the left and right bin walls limits the screening screen plate 86, located directly below the filter hopper 771; the material falling from the filter hopper 771 undergoes secondary screening on the screening screen plate 86; since its mesh diameter is smaller than that of the filter screen 778, it can further remove more pollutants. Small particulate impurities are removed by the sliding connection of the screening screen 86 between the left and right walls of the recycling box 81, which facilitates removal and cleaning. The screen 86 is placed on the lower wall of the recycling box 81, directly below the screening screen 86, to collect the material after two screenings. The multi-structure design of the recycling box 81 ensures the orderly cooperation and stable operation of each component. The secondary screening by the screening screen 86 further improves the purity of the material. The collection box 85 facilitates the collection of finished materials and centralized processing. The overall collection device 8 is reasonably designed and effectively improves the efficiency and quality of furnace ash filtration and recovery in zinc oxide production.

[0036] It should be noted that this utility model is a furnace ash filtration and recovery structure for zinc oxide production. During use, the material containing furnace ash is first fed into the chuck box 776 located directly below it through the feed pipe 5. The outer surface of the chuck box 776 has several filter screens 778 for preliminary filtration of the material. The chuck box 776 is engaged with the locking strip 772 inside the filter hopper 771 via a locking groove 777. The filter hopper 771 has a conical structure and its outer surface does not contact the inner wall of the recovery box 81. It slides within the groove 83 of the recovery box 81 via a pulley slider 775. Simultaneously, the filter hopper 771 is fixed to the left end of the linkage plate 76, and the drive motor 71 starts, its output end carrying… The main pulley 72 rotates, and the main pulley 72 causes the driven pulley 73 to rotate via the belt 74. The fixed rod 75 on the driven pulley 73 rotates with it, thereby driving the linkage plate 76 to move. The linkage plate 76 moves back and forth in the movable groove 82, which in turn drives the filter bucket 771 and its internal chuck box 776 to shake back and forth, so that the material is further filtered in the filter bucket 771. The furnace ash material after being screened by the screening screen 86 falls into the collection box 85. The collection box 85 is located on the lower wall of the recovery box 81. The box door 1 can be opened periodically to take out the collection box 85 to clean the collected furnace ash. During the entire filtration and recovery process, the working condition of the equipment can be observed through the observation round window 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
