Description

[0002] Cemented carbide is a hard compound of refractory metals, which can be made into a variety of parts for use. However, some parts made of cemented carbide may be worn and unusable. Some manufacturers will recycle these unusable parts made of cemented carbide. When recycling, some parts made of cemented carbide need to be crushed in a ball mill, and then cleaned and dried to ensure the uniformity of the cemented carbide and provide convenience for later processing.

[0003] In the prior art, when some ball mills are in use, some cemented carbides are relatively dry.

It can dry the materials after filter pressing processing and improve the subsequent processing efficiency. The right surface of the drying box 4 is fixedly connected with a feed pipe 26. The feed pipe 2 6 is used to feed the dried material into the interior of the air flow mill. A pump body is provided in the middle of the feed pipe 2 6. The pump body can transport the metal powder, which improves the practicality. The right surface of the top of the feed pipe 2 6 is fixedly connected with the air flow mill body 5. The air flow mill body 5 is in the prior art. The dried material can be further polished through it to improve the quality of the material. A cleaning component is provided on the upper surface of the ball mill body 1, a protective component is provided on the upper surface of the drying box 4, and a stirring component is provided on the inner wall of the drying box 4. The cleaning component includes a stirring rod 71. The stirring rod 71 is driven by a motor, which can improve the efficiency of polishing. The stirring rod 71 is rotatably connected to the upper surface of the ball mill body 1. The outer wall of the top of the stirring rod 71 is provided with a water inlet 711. Water can be sent into the interior of the ball mill body 1 through the water inlet 711. The material can be cleaned inside the ball mill body 1, and the grinding speed of some relatively dry cemented carbides can also be improved. The outer wall of the top of the stirring rod 71 is slidably connected with a water inlet pipe 72. The right end of the water inlet pipe 72 is annular and wrapped around the outer wall of the stirring rod 71, and at the same time wraps the water inlet 711 to ensure the smoothness of water supply. The lower surface of the water inlet pipe 72 is fixedly connected to the upper surface of the ball mill body 1

[0033] Reference Figure 2 - Figure 3 、 Figure 5 The inner wall of the top end of the stirring rod 71 is slidably connected with a round block 75, and the lower surface of the round block 75 is fixedly connected with an extrusion bar 79. The lower surface of the left end of the extrusion bar 79 is set as an inclined surface to ensure that when it moves downward, it can push the scraper 73 to move to the right and away from the inner wall of the ball mill body 1, avoiding long-term contact and causing damage to the inner wall of the ball mill body 1. The extrusion bar 79 slides on the lower side of the inner wall of the stirring rod 71 near the water inlet 711.

[0034] Reference Figure 1 、 Figure 4 The protective component includes a cover plate 81, which is fixed to the drying box 4 using a clip. The clip is a prior art and can be implemented by technicians in this field, so it will not be described in detail in this case. The cover plate 81 is slidably connected to the upper surface of the drying box 4, and a water outlet 82 is provided on the rear side of the inner wall of the cover plate 81. The water outlet 82 is provided to ensure that the filtered water can be discharged smoothly when it falls on the inner wall of the cover plate 81. The stirring component includes a rotating rod 92, which is rotatably connected to the inner wall of the drying box 4. The left surface of the rotating rod 92 is fixedly connected to the motor 91. The motor 91 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The motor 91 is fixedly connected to the left surface of the drying box 4. Starting the motor 91 can drive the rotating rod 92 to rotate, and at the same time drive the stirring blade 93 to rotate, stir the product, break up the filtered product, and improve the drying effect. The outer wall of the rotating rod 92 is fixedly connected with stirring blades 93, and there are multiple groups of stirring blades.

[0035] Reference Figure 2 、 Figure 5 The cleaning component also includes a water outlet pipe 74, which rotates with the stirring rod 71 to ensure that water can be evenly sprinkled on the inner wall of the ball mill body 1. The water outlet pipe 74 is fixedly connected to the left surface of the stirring rod 71, and the upper surface of the water outlet pipe 74 slides on the upper side of the inner wall of the ball mill body 1. The left end of the extrusion bar 79 slides on the inner wall of the water outlet pipe 74, and the inner wall of the top of the round block 75 is elastically connected to the slide plate 77 through a spring 1 76. The spring 1 76 always pushes the slide plate 77 to move to the left through its own elasticity to ensure the stability of the limit rod 78. The slide plate 77 is slidably connected to the inner wall of the top of the round block 75, and one end of the spring 1 76 is fixedly connected to the inner wall of the top of the round block 75, and the other end of the spring 1 76 is fixedly connected to the right surface of the slide plate 77.

[0036] Reference Figure 2 、 Figure 5The left surface of the slide plate 77 is fixedly connected to the limit rod 78, and the limit rod 78 is adapted to the through hole to ensure the stability of the limit. The limit rod 78 is slidably connected to the left surface of the top of the round block 75. A through hole is provided on the left surface of the top of the stirring rod 71. The limit rod 78 slides through the inner wall of the through hole. There are multiple groups of through holes. One group is the extrusion bar 79 that pushes the scraper 73 out of the limit of the inner wall of the ball mill body 1, and the other group is the opposite. The left surface of the slide plate 77 is fixedly connected to the pull rod 710, which slides through the left surface of the top of the stirring rod 71 near the front side of the through hole, and the pull rod 710 is slidably connected to the left surface of the top of the round block 75 near the rear side of the limit rod 78.

[0037] Reference Figure 2 - Figure 3 、 Figure 6 The cleaning component also includes a scraper 73. The left surface of the scraper 73 is set to an arc surface, which is adapted to the amplitude of the inner wall of the ball mill body 1, thereby improving the cleaning effect. The left surface of the scraper 73 slides on the inner wall of the ball mill body 1. When the extrusion bar 79 does not contact the scraper 73, water can be released. The impact force of the flowing water and the centrifugal force of the rotation will cause the scraper 73 to contact the inner wall of the ball mill body 1 for cleaning. The top of the scraper 73 passes through and is slidably connected to the lower surface of the left end of the water outlet pipe 74. The lower side surface of the inner wall of the water outlet pipe 74 is set to an inclined surface to ensure the impact force of the water flow. The right surface of the top of the scraper 73 is fixedly connected to a protective plate 712, and the water inlet pipe 72 is slidably connected to the inner wall of the left end of the water outlet pipe 74 near the right side of the top of the scraper 73.

[0038] Working principle: The equipment is mainly composed of a ball mill body 1, a feed pipe 2, a filter press body 3, a drying box 4, a feed pipe 6 and an air flow mill body 5, and is equipped with a cleaning component, a protective component and a stirring component, which can ensure that the recovered cemented carbide is cleaned and dried without manual operation, thereby improving practicality.

[0039] In the ball mill body 1, the stirring rod 71 is driven to rotate by the motor. When cleaning is required, water enters the stirring rod 71 through the water inlet pipe 72 and the water inlet 711, and is then evenly sprinkled out from the water outlet pipe 74. At the same time, the scraper 73 contacts the inner wall of the ball mill body 1 under the impact force of the water flow and the centrifugal force of rotation to clean the adhered products. When the scraper 73 needs to be separated from the inner wall, the pull rod 710 can be pushed. The pull rod 710 will drive the slide plate 77 to move and squeeze the spring 1 76, and at the same time drive the limit rod 78 to move away from the inner wall of the through hole. This can push the round block 75 to move, and the round block 75 will drive the extrusion bar 79 to move. At the same time, the scraper 73 will move along the inclined surface of the extrusion bar 79 and separate from the inner wall of the ball mill body 1. Then loosen the pull rod 710, and the spring 1 76 will push the slide plate 77 to reset through its own elasticity, and the limit rod 78 will then be inserted into the inner wall of another set of through holes.

[0040] The product after ball milling is fed into the filter press body 3 through the feed pipe 2 under the action of the sludge pump for solid-liquid separation. The separated material is placed in the drying box 4. The rotating rod 92 in the drying box 4 drives the stirring blade 93 to rotate under the drive of the motor 91, stirring and breaking up the material to improve the drying effect. In the process of filtration, moisture will enter the inner wall of the cover plate 81 and be discharged through the water outlet 82.

[0041] The dried material is fed into the air flow mill body 5 through the feed pipe 2 6 under the action of the pump body for further grinding to improve the material quality. The cover plate 81 in the protective component is fixed to the upper surface of the drying box 4 by a snap, and the water outlet 82 on the rear side of the inner wall ensures the smooth discharge of the filtered water.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
