Technical Field

[0001] The invention relates to a tungsten recovery pretreatment device, in particular to a tungsten recovery pretreatment filtering device and method. Background Art

[0002] Tungsten is a metallic element. Its single substance is a shiny silvery-white metal with high hardness and melting point. It is not corroded by air at room temperature and has relatively stable chemical properties. It is mainly used to manufacture filaments, high-speed cutting alloy steels, and super-hard molds. It is also used in optical instruments and chemical instruments. During the tungsten metal processing, a small amount of tungsten material falls into the melt or water to form tungsten mud, which needs to be recycled.

[0003] The current process of tungsten sludge recycling generally involves filtering and removing impurities from the tungsten sludge, first manually picking out the larger garbage in the tungsten sludge, then manually removing most of the liquid in the sludge, and finally removing the moisture in the tungsten sludge by calcination to obtain tungsten refining raw materials. In this process, most of the process requires human participation, and tungsten sludge is likely to remain on the garbage manually removed from the tungsten sludge, and the remaining tungsten sludge is not completely collected. The entire pretreatment process has problems such as slow filtration efficiency and low tungsten sludge recycling rate. Summary of the invention

[0016] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail in conjunction with the accompanying drawings. It is hereby stated that the directional words such as upper, lower, left, right, front, back, inside and outside that appear or will appear in the present invention are only based on the drawings of the present invention, and are not specific limitations of the present invention. The serial numbers of the parts in this article, such as: first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The terms such as connection and connection in this application include direct and indirect connection (connection) unless otherwise specified.

[0017] Example 1: A tungsten recovery pretreatment filtering device, such as Figure 1-4 As shown, it includes a bracket 1, a discharge hopper 2, a connecting frame 30, a first motor 31, a convex plate 32, a first slide bar 33, a mesh plate 34, a connecting plate 37, a discharge frame 3, an articulated frame 41 and a discharge hopper 4. The upper part of the bracket 1 is inclinedly installed with a discharge frame 3 with an opening at the lower part. The upper part of the discharge frame 3 is rotatably connected with an articulated frame 41, and the articulated frame 41 is welded with the discharge hopper 4. The discharge frame 3 is connected with the discharge hopper 4. The lower left part of the discharge hopper 4 is provided with a discharge port 42. The bracket 1 below the discharge hopper 4 is installed with a discharge hopper 2, and the lower right part of the discharge hopper 2 is provided with a discharge port 21. The left part of the feeding frame 3 is connected to a connecting frame 30, and the left part of the connecting frame 30 is installed with a first motor 31. The output shaft key of the first motor 31 is connected with a cam 32, and the cam 32 is connected with a first slide bar 33. The lower bottom surface of the feeding frame 3 is slidably connected with a mesh plate 34. The mesh plate 34 is provided with a first slide groove 35 which is plugged with the first slide bar 33 to control the rotation of the first motor 31, and then the mesh plate 34 is driven to slide up and down along the lower bottom surface of the feeding frame 3 through the cam 32 and the first slide bar 33, so as to vibrate and screen the tungsten mud and the large pieces of garbage mixed in the tungsten mud.

[0018] like Figure 5 As shown, it also includes an ejection mechanism, which includes a second motor 51, a push plate 52 and a screw rod 5. The second motor 51 is installed inside the connecting frame 30, and the output shaft of the second motor 51 is connected to the screw rod 5. The screw rod 5 is threadedly connected to the push plate 52 which is slidably connected to the mesh plate 34. When it is necessary to clean the garbage on the mesh plate 34, first move the lower hopper 4 upward so that it rotates counterclockwise around the upper part of the lower material frame 3 together with the articulated frame 41, and then flip the lower hopper 4 open so that it no longer blocks the outlet of the upper part of the lower material frame 3, and then the garbage can be cleaned out. When the second motor 51 rotates, it can drive the push plate 52 to slide along the screw rod 5, thereby pushing out the garbage on the mesh plate 34.

[0019] like Figure 5As shown, it also includes a top plate 53. The right end face of the push plate 52 is connected to the top plate 53 for pushing open the lower hopper 4. After the top plate 53 is installed, when the second motor 51 is started to rotate and then drive the push plate 52 to slide along the screw rod 5, the top plate 53 can be driven to move at the same time. As the push plate 52 continues to move upward, the top plate 53 first contacts the lower hopper 4, and then pushes the lower hopper 4 open, so that the push plate 52 can push the garbage on the mesh plate 34 out.

[0020] like Figure 6 and Figure 7 As shown, it also includes a curved plate 61, a locking rod 62, a connecting rod 64, a second sliding rod 65, a connecting plate 37, a spring 66 and a support shaft 6. The support shaft 6 is fixedly connected to one end of the side wall of the blanking frame 3 close to the blanking hopper 4, and the support shaft 6 is rotatably connected to the curved plate 61. The right end of the curved plate 61 is connected to the locking rod 62 for locking the hinge frame 41. The left end of the curved plate 61 is provided with a third slide groove 63, and the third slide groove 63 is slidably connected with the connecting rod 64. The side wall of the blanking frame 3 is provided with a second slide groove 36, and the left end of the connecting rod 64 is connected to the second slide rod 65 which is plugged and matched with the second slide groove 36. The second slide rod 65 is located on the left side of the push plate 52, and the side wall of the blanking frame 3 is connected to the connecting plate 37. A spring 66 is connected between the connecting plate 37 and the connecting rod 64. Initially, the push plate 52 is located at the lower end of the screw rod 5, and the spring 66 is in a stretched state. The connecting rod 64 is within the blocking limit of the push plate 52 and the second slide rod 65 The locking rod 62 is pressed against the hinge frame 41, so that the top plate 53 gradually contacts with the lower hopper 4 and pushes the lower hopper 4 open, so that the push plate 52 pushes out the garbage screened on its surface.

[0021] like Figure 8 and Fig. 9As shown, it also includes a water pipe 7, a shunt pipe 71 and a nozzle 72. The water pipe 7 is installed on the upper part of the feeding frame 3. The water pipe 7 is connected to the shunt pipe 71. The shunt pipe 71 passes through the inside of the feeding frame and is connected to the nozzle 72. Since tungsten mud is easy to adhere to the surface of some garbage, the garbage can be sprayed and washed by installing the nozzle 72 on the top of the feeding frame 3 to fully recover the tungsten powder raw material. Optionally, the side wall of the feeding frame 3 can be set to a transparent material to facilitate observation of whether the garbage and debris on the mesh plate are washed clean. At the same time, a spherical nozzle 72 with a valve is selected to perform multi-directional flushing on the garbage and debris on the mesh plate to improve the flushing effect.

[0022] Embodiment 2: A tungsten recovery pretreatment filtering method, based on the tungsten recovery pretreatment filtering device, comprises the following steps: Step 1: Pour the tungsten mud to be recycled and filtered into the lower hopper 4, start the first motor 31, drive the mesh plate 34 to slide up and down along the bottom surface of the lower frame 3 through the convex plate 32 and the first slide bar 33, and then vibrate and screen the tungsten mud and the large pieces of garbage mixed in the tungsten mud until only large pieces of garbage and debris are left on the mesh plate 34, and then stop running the first motor 31; Step 2: Pass a flushing liquid (such as water or sodium chloride) into the water pipe 7 and open the valve of the nozzle 72 to spray and flush the large pieces of garbage and debris left on the mesh plate 34 until the tungsten mud attached to the garbage and debris is washed off; Step 3: Start the second motor 51, which drives the push plate 52 to slide along the screw rod 5. After the top plate 53 gradually contacts the lower hopper 4 and pushes the lower hopper 4 open, the push plate 52 is used to push out the garbage on the mesh plate 34. Step 4: After controlling the second motor 51 to reverse and reset the push plate 52, stop the second motor 51 and return to step 1.
