Description

Technical Field

[0001] This utility model belongs to the field of secondary zinc oxide processing technology, specifically relating to a secondary zinc oxide filtration and discharge device. Background Technology

[0002] In the production of zinc oxide by volatilization kilns, with the development and progress of the industry, the requirements for the refinement and efficiency of production processes are constantly increasing. On the one hand, the market has increasingly stringent quality standards for zinc oxide products, requiring extremely precise control over purity, particle size distribution, and other physicochemical properties. This necessitates that the raw material feeding process be carried out precisely according to the predetermined formula and metering to ensure that the chemical reaction within the volatilization kiln proceeds stably and efficiently, thereby producing products that meet high-quality requirements.

[0003] Meanwhile, the patent specification with application number CN203095638U discloses an automatic sedimentation collection device, which "includes a collection box, with an inlet at the top and several outlets at the bottom; and also includes a collection device located below the outlets. The collection device includes several collection hoppers and a screw conveyor. The outlets of the collection hoppers and the collection box correspond one-to-one. The upper part of the collection hopper is connected to the outlet, and the lower part is connected to the screw conveyor."

[0004] Existing zinc oxide volatilization kiln feeding devices often fail to adequately filter zinc oxide during operation, allowing impurities to easily mix into the zinc oxide and enter subsequent processes, affecting production quality. Secondly, the fixed outlet positions of most existing devices result in poor adaptability when used with volatilization kilns of different specifications, often requiring the construction of complex connecting structures or adjustments to the overall device placement, making operation extremely inconvenient and increasing labor and time costs. Therefore, this paper proposes a zinc oxide filtration and discharge device to address these issues. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 As shown, this utility model embodiment provides a zinc oxide filtration and discharge device, specifically including a counterweight plate 1. The top of the counterweight plate 1 is fixedly connected to a filter box 7 via a bracket. The inner surface of the filter box 7 is provided with a filter assembly 4. The filter assembly 4 includes a first motor 47, which is fixedly connected to the filter box 7. The output end of the first motor 47 is fixedly connected to a first gear 46. The outer surface of the first gear 46 is meshed with a gear ring 42. The inner surface of the gear ring 42 is fixedly sleeved with a filter frame 44. The bottom end of the filter frame 44 is rotatably connected to the top of the filter box 7. The bottom end of the filter frame 44 is fixedly connected to a filter screen 45. The outer surface of the filter screen 45 is provided with spiral blades 41. The outer surface of the spiral blades 41 is in contact with the inner surface of the filter box 7, which can effectively filter zinc oxide, effectively block large particulate impurities from entering the subsequent system, ensure the purity of zinc oxide, and help improve the stability of the reaction in the volatilization kiln and product quality, and reduce equipment failure and product defect rate caused by impurities. Four rollers 2 are fixedly connected to the bottom of the counterweight plate 1, and a push rod 3 is fixedly connected to the top of the counterweight plate 1, giving the feeding device good mobility. Operators can easily push the device to move within the work area, facilitating feeding operations in different locations and improving the flexibility of the device.

[0028] Please see Figures 1 to 5 As shown, the top of the filter frame 44 has an annular groove 43, and the top of the filter frame 44 has a sealing cover 5. The bottom of the sealing cover 5 is fixedly connected to an annular sealing strip that matches the annular groove 43. The top of the sealing cover 5 is fixedly connected to a handle, which effectively enhances the sealing performance of the filter box 7. During the secondary zinc oxide filtration process, this prevents dust and other impurities from splashing, improving the working environment. The bottom of the filter box 7 is fixedly connected to a hopper 8, and the bottom of the hopper 8 is fixedly connected to a conveying pipe 6. The conveying pipe 6 is fixedly connected to the counterweight plate 1 through a fixing frame. The hopper 8 can play a buffering and guiding role, allowing the filtered secondary zinc oxide to flow smoothly into the conveying pipe 6, ensuring the continuity of the secondary zinc oxide conveying. The conveying pipe 6 and the counterweight plate 1 are connected through a fixing frame, which enhances the stability of the conveying pipe 6.

[0029] Please see Figures 1 to 5As shown, a toothed column 63 is slidably sleeved on the inner surface of the conveying pipe 6, and an inner tube 64 is fixedly sleeved on the inner surface of the toothed column 63. A rectangular groove 612 is opened on the outer surface of the conveying pipe 6, and a protective box 65 is fixedly connected to the outer surface of the conveying pipe 6. A second gear 67 is rotatably connected to the inner walls of both sides of the protective box 65. The second gear 67 passes through the rectangular groove 612 and meshes with the outer surface of the toothed column 63. A second motor 66 is fixedly connected to the outer surface of the protective box 65. The output end of the second motor 66 passes through one end of the protective box 65 and is fixedly connected to the second gear 67. This allows the outlet position of the conveying pipe 6 to be adjusted according to actual needs, adapting to the feed inlets of volatilization kilns of different heights and positions, thus improving the versatility and adaptability of the device.

[0030] In this embodiment, a limiting plate 632 is fixedly connected to the bottom end of the toothed column 63. The outer surface of the limiting plate 632 is coated with a sealing paint. Two guide blocks 631 are fixedly connected to the outer surface of the limiting plate 632. The inner surface of the conveying pipe 6 is provided with a guide groove 611 that cooperates with the two guide blocks 631. This ensures the extension and retraction of the inner pipe 64 while effectively preventing the leakage of secondary zinc oxide from the gap between the toothed column 63 and the conveying pipe 6, thereby improving the sealing performance of the device and the accuracy of the secondary zinc oxide delivery. The cooperation between the guide block 631 and the guide groove 611 ensures the stability and straightness of the toothed column 63 during the extension and retraction process, and prevents the toothed column 63 from deviating.

[0031] like Figures 1 to 5 As shown, a collection box 68 is fixedly connected to one end of the inner tube 64. A vacuum pump 69 is installed at the top of the collection box 68, and a discharge pipe 61 is fixedly connected to the bottom of the collection box 68. An electric valve 62 is installed on the outer surface of the discharge pipe 61. The collection box 68 can generate negative pressure under the action of the vacuum pump 69, which helps to draw in and collect secondary zinc oxide from the end of the conveying pipe 6, thereby improving the collection efficiency of secondary zinc oxide. After collection, the secondary zinc oxide can fall into the volatilization kiln by opening the electric valve 62.

[0032] The structure of the electric motor is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0033] Working principle and process: First, open the sealing cover 5 and pour the secondary zinc oxide into the filter screen 45 at the bottom of the filter frame 44. Then, turn on the first motor 47. The first motor 47 drives the first gear 46 to rotate, and the gear ring 42 of the first gear 46 rotates. The gear ring 42 drives the filter frame 44 to rotate at the top of the filter box 7. Under the action of centrifugal force, the filter screen 45 at the bottom of the filter frame 44 filters the secondary zinc oxide, intercepting impurities. The spiral blades 41 on the surface of the filter screen 45 continuously push the secondary zinc oxide to move in the filter box 7 as the filter frame 44 rotates, while also preventing the secondary zinc oxide from sticking to the inner wall of the filter box 7. After filtration, the secondary zinc oxide falls into the hopper 8 at the bottom of the filter box 7. Then, the secondary zinc oxide enters the conveying pipe 6 from the hopper 8. When it is necessary to adjust the position of the discharge port of the conveying pipe 6, The second motor 66 outside the protective box 65 is started. The second motor 66 drives the second gear 67 to rotate. The second gear 67 drives the toothed column 63 to slide along the guide groove 611 inside the conveying pipe 6. The toothed column 63 drives the inner pipe 64 to rise or fall, thereby changing the position of the discharge port to adapt to the requirements of different volatilization kiln feed ports. Finally, the collection box 68 at one end of the inner pipe 64 generates negative pressure under the action of the vacuum pump 69, which draws the secondary zinc oxide in the conveying pipe 6 into the collection box 68. When it is necessary to discharge the secondary zinc oxide in the collection box 68 into the volatilization kiln, the electric valve 62 outside the discharge pipe 61 is opened. Under the combined action of gravity and negative pressure, the secondary zinc oxide is accurately discharged into the volatilization kiln through the discharge pipe 61. The electric valve 62 can accurately control the discharge flow rate and time, ensuring that the entire feeding process is stable, efficient and accurate.
