Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum liquid filtration equipment, specifically to a dual-filter plate aluminum liquid filtration box. Background Technology
[0002] After the molten aluminum flows out of the melting furnace, it flows through the flow channel into the mold of the casting machine for casting. Since the molten aluminum is not filtered and flows directly into the mold, it contains aluminum slag and other impurities, which causes the purity of the molten aluminum in the mold to not meet the requirements and thus does not meet the product quality requirements. At present, a double-filter plate aluminum molten aluminum filtration box is generally used to perform secondary filtration of the molten aluminum.
[0003] A search revealed that publication number CN207288882U discloses a dual-plate aluminum liquid filtration box, comprising a box body, a box cover, and support legs. The box body is lined with a refractory layer, which includes a first aluminum liquid filtration pool and a second aluminum liquid filtration pool connected thereto. One end of the box body has an aluminum liquid inlet, and the other end opposite the inlet has an aluminum liquid outlet. A first filter plate and a second filter plate are respectively positioned above the first and second aluminum liquid filtration pools. The aluminum liquid inlet is located above the first filter plate, and the aluminum liquid outlet is located at the bottom of the second aluminum liquid filtration pool.
[0004] The above-mentioned utility model adds two filter plates in the filter box and adds a first filter pool and a second filter pool. The flow rate of aluminum liquid can not only be doubled, solving the problem of insufficient aluminum liquid flow, but also filter out the impurities contained in the aluminum liquid, improving the purity of the aluminum liquid and increasing production efficiency. However, when filtering aluminum liquid through two sets of filter plates, some impurities will accumulate after the aluminum liquid is filtered, which can easily clog the filter plates and gradually reduce the filtration efficiency of the aluminum liquid.
[0005] Therefore, it is of great importance to design a dual-plate aluminum liquid filter box to solve the above-mentioned defects. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example: Please refer to Figures 1-4 This utility model provides a technical solution:
[0026] A dual-plate aluminum liquid filtration box includes a box body 1. The front and rear sides of the box body 1 are respectively provided with an inlet 2 and an outlet 3. The front and rear ends of the box body 1 are respectively provided with a first aluminum liquid filtration pool 4 and a second aluminum liquid filtration pool 5, and the first aluminum liquid filtration pool 4 and the second aluminum liquid filtration pool 5 are connected to each other. A first filter plate 6 and a second filter plate 7 are respectively provided above the first aluminum liquid filtration pool 4 and the second aluminum liquid filtration pool 5. Cleaning components 8 are fixedly installed on the outside of the box body 1 at positions corresponding to the first aluminum liquid filtration pool 4 and the second aluminum liquid filtration pool 5.
[0027] First, in this embodiment, the specific structure of the cleaning component 8 is as follows:
[0028] The cleaning component 8 includes two sets of mounting brackets 801 fixedly installed at the front and rear ends of the right side of the housing 1. A drive motor 802 is fixedly installed at the front end of the top of each set of mounting brackets 801. A support bracket 803 is fixedly installed at the top of each set of mounting brackets 801 and behind the drive motor 802. A guide post 804 is rotatably connected to the top of each set of support brackets 803, and the drive end of the drive motor 802 is fixedly connected to the front end of the guide post 804. A movable bracket 805 is slidably connected to the bottom end of the inner side of each set of support brackets 803. The bottom end of the movable bracket 805 is slidably connected to the outer side of the guide post 804 via a guide slider 806. The movable bracket 805 is located inside the housing 1. A cleaning plate 807 is fixedly installed at one end of the filter and on top of the first filter plate 6 and the second filter plate 7. After the aluminum liquid is filtered by the first filter plate 6 and the second filter plate 7, impurities will accumulate over a long period of filtration. At this time, the drive motor 802 is started to drive the guide column 804 to rotate. Under the connection of the guide slider 806, the bottom end of the moving frame 805 moves back and forth inside the support frame 803, thereby driving the cleaning plate 807 to move back and forth on the surface of the first filter plate 6 and the second filter plate 7 to clean the accumulated impurities, avoid the accumulation of impurities and blockage, and at the same time, it can agitate the aluminum liquid to improve its fluidity, thereby ensuring the filtration effect of the aluminum liquid.
[0029] Furthermore, the bottom end of the movable frame 805 is slidably connected to the support frame 803 via the slide rod 808, and the guide slider 806 is slidably connected to the outer side of the guide post 804 via the guide groove 809. When the guide post 804 rotates, the guide slider 806 slides inside the guide groove 809. Under the guidance of the guide groove 809 and the connection of the slide rod 808, the bottom end of the movable frame 805 is driven to move back and forth inside the support frame 803, thereby driving the cleaning plate 807 to move back and forth on the surfaces of the first filter plate 6 and the second filter plate 7 to clean the accumulated impurities.
[0030] Then, a movable groove is provided on the outer side of the housing 1 at the position corresponding to the movable frame 805. A movable cover 810 is fixedly installed on the outer side of the movable groove, and the movable frame 805 is slidably connected to the inside of the movable cover 810. When the movable frame 805 moves, its top end slides inside the movable cover 810, thereby ensuring the moving stability of the movable frame 805.
[0031] Furthermore, the top of the box 1 is hinged with a box cover 101. The inner sides of the box 1 and the box cover 101 are respectively provided with a heat insulation layer 102 and a refractory layer 103. When the box 1 filters the aluminum liquid, the box cover 101 is closed to prevent the internal temperature from losing too quickly. At the same time, the box cover 101 can be opened to clean the inside of the box 1. The heat insulation layer 102 is made of lightweight high alumina bricks or lightweight mullite bricks. These materials achieve heat insulation through high porosity and are suitable for high temperature environments of aluminum liquid. The refractory layer 103 is made of high alumina bricks or alumina castable. Due to its high alumina content, it can effectively resist the erosion of aluminum liquid and chemical corrosion, thereby effectively improving the service life of the box 1.
[0032] The bottom left and right ends of the box body 1 are fixedly connected to forklift sleeves 104, the front end of the top of the box cover 101 is fixedly connected to a main lifting lug 105, and the top of the box cover 101, which is located above the first filter plate 6 and the second filter plate 7, is hinged to an observation door 106. The top of the two sets of observation doors 106 are fixedly connected to auxiliary lifting lugs 107. The forklift can be inserted into the forklift sleeve 104 to move the box body 1. When the box cover 101 is opened, the main lifting lug 105 can be lifted by the lifting equipment to open the box cover 101. At the same time, the auxiliary lifting lug 107 can be lifted to open the observation door 106, so as to observe the state of the aluminum liquid in various places inside the box body 1.
[0033] Secondly, temperature measuring thermocouples 108 are fixedly installed inside the box 1 and above the first filter plate 6 and the second filter plate 7. A preheating air duct 109 is fixedly connected to the middle of the top of the box 1. Multiple sets of electric heating tubes 110 are fixedly installed inside the preheating air duct 109. After the aluminum liquid enters the box 1 through the flow channel, degassing equipment and other devices, the temperature of the aluminum liquid will drop to a certain extent, causing aluminum solid particles to separate out and easily block the filter holes of the first filter plate 6 and the second filter plate 7. To avoid this situation, the internal temperature of the box 1 is monitored in real time by the temperature measuring thermocouples 108 before casting begins. Then, the electric heating tubes 110 inside the preheating air duct 109 are activated and connected to an external blower to blow in hot air to quickly preheat the inside of the box 1, thereby further reducing the risk of blockage of the first filter plate 6 and the second filter plate 7.
[0034] Finally, a cover 111 is hinged to the top of the preheating air duct 109, and a guide hood 112 is fixedly connected inside the box 1 and at the bottom of the preheating air duct 109. The cover 111 is closed when the box 1 is working with the aluminum liquid. When preheating the inside of the box 1, the guide hood 112 can improve the diffusion effect of hot air, thereby uniformly preheating the inside of the box 1.
[0035] In this embodiment, the specific implementation scenario is as follows: Before casting begins, the internal temperature of the chamber 1 is monitored in real time using a thermocouple 108. Then, the heating element 110 inside the preheating duct 109 is activated and connected to an external blower to quickly preheat the interior of the chamber 1 with hot air. Afterward, molten aluminum is introduced through the inlet 2 and filtered sequentially through the first filter plate 6 and the second filter plate 7. The filtered molten aluminum flows into one end of the first aluminum molten aluminum filtration pool 4 and the second aluminum molten aluminum filtration pool 5, and is finally discharged through the outlet 3. After filtration using the first filter plate 6 and the second filter plate 7, impurities accumulate over time. At this time, the drive motor 802 is started to drive the guide column 804 to rotate. Under the connection of the guide slider 806, the bottom end of the moving frame 805 moves back and forth inside the support frame 803, thereby driving the cleaning plate 807 to move back and forth on the surface of the first filter plate 6 and the second filter plate 7 to clean the accumulated impurities, avoid the accumulation of impurities and blockage, and at the same time, it can stir the aluminum liquid to improve its fluidity. The whole operation process is simple and convenient. This utility model reduces the risk of blockage by preheating treatment in advance, and can clean the accumulated impurities to avoid the accumulation of impurities and blockage. It can also improve the fluidity of aluminum liquid and ensure the filtration effect of aluminum liquid.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
