Description

Technical Field

[0001] This utility model relates to the field of cemented carbide mixed slurry preparation, and in particular to a cemented carbide wet grinding slurry screening device. Background Technology

[0002] In the production process of cemented carbide, the quality of the mixed slurry has a crucial impact on the quality of the finished cemented carbide product. Therefore, after the mixed material is ball-milled into a mixed slurry during the cemented carbide production process, it contains many impurities and must be filtered before it can be discharged.

[0003] Filtration requires screening equipment, such as a prior art screening device for hard alloy mixed slurry. This device consists of a support frame and a drive unit mounted on the support frame. Slide rails are located on the inner sides of both ends of the support frame, and a movable frame that can reciprocate along the slide rails is positioned between the two ends. A filter device is mounted on the movable frame, and an extension rod is located on the side of the movable frame closest to the drive unit. A rotating disk is mounted on the drive unit, and the end of the extension rod furthest from the filter device is hinged to the rotating disk. The hard alloy mixed slurry screening device of this application uses the rotation of the drive unit to drive the filter device in a variable-speed reciprocating motion, enabling the filter device to achieve efficient and rapid filtration of the mixed slurry while ensuring its quality.

[0004] However, the equipment lacks a structure to limit the filter barrel located on the inner side of the moving frame when it moves. As a result, the filter barrel is prone to collision with the inner side of the moving frame when the frame moves. Furthermore, the equipment simply moves the slurry back and forth for screening, which is too simplistic and results in mediocre screening effect, failing to meet higher production quality requirements.

[0005] Therefore, it is necessary to provide a screening device for wet abrasive slurry of cemented carbide to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a screening device for wet abrasive slurry of cemented carbide, which solves the problems of easy collision between the moving frame and the filter barrel, and poor screening effect due to the single screening method.

[0011] A receiving bucket, wherein the receiving bucket is disposed at the bottom of the filter bucket;

[0012] Four fixed plates are respectively fixedly installed around the top of the support frame. A sliding rod is fixedly installed between the middle of two of the fixed plates. A drive motor is fixedly installed on one side of one of the fixed plates. A reciprocating screw is fixedly installed at the output end of the drive motor. One end of the reciprocating screw is rotatably connected to one side of the other fixed plate. Sliding blocks are fixedly installed at both ends of the top of the movable frame. Moving blocks are slidably connected to the outer sides of the two sliding blocks. One moving block is threaded to the outer side of the reciprocating screw, and the other moving block is slidably connected to the outer side of the sliding rod.

[0013] Preferably, support rods are fixedly installed around the bottom of the support frame, and a base plate is fixedly installed at the bottom of each of the four support rods.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a cemented carbide wet abrasive slurry screening device provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure; Figure 3 for Figure 1The diagram shows a partial cross-sectional view of the support frame. A cemented carbide wet abrasive slurry screening device includes: a support frame 12, the top of which has two grooves 13, and the inner sides of the two grooves 13 are fixedly mounted with first toothed plates 14;

[0029] A movable frame 4 is disposed on the top of the support frame 12. Two second toothed plates 41 are fixedly installed on the bottom of the movable frame 4. The second toothed plates 14 are slidably connected to the inner side of the slide groove 13 and located on the top of the first toothed plates 14. Side frames 42 are fixedly installed on both sides of the movable frame 4. An adjusting rod 43 is threadedly connected to the inside of the side frame 42. One end of the adjusting rod 43 is rotatably connected to a clamping frame 44.

[0030] A filter bucket 5 is disposed on the inner side of the movable frame 4. A handle 51 is fixedly installed on the top of both sides of the filter bucket 5. The handle 51 is disposed on the top of the movable frame 4.

[0031] Material receiving bucket 3 is disposed at the bottom of the filter bucket 5;

[0032] Four fixed plates 2 are respectively fixedly installed around the top of the support frame 12. A sliding rod 21 is fixedly installed in the middle of two of the fixed plates 2. A drive motor 22 is fixedly installed on one side of one of the fixed plates 2. A reciprocating screw 25 is fixedly installed at the output end of the drive motor 22. One end of the reciprocating screw 25 is rotatably connected to one side of the other fixed plate 2. Sliding blocks 24 are fixedly installed at both ends of the top of the movable frame 4. Moving blocks 23 are slidably connected to the outer sides of the two sliding blocks 24. One moving block 23 is threaded to the outer side of the reciprocating screw 25, and the other moving block 23 is slidably connected to the outer side of the sliding rod 21.

[0033] The outer side of the second toothed plate 41 is in contact with the inner side of the slide groove 13. In this way, when the moving frame 4 moves, the second toothed plate 41 can slide on the inner side of the slide groove 13, thereby playing a limiting role.

[0034] By having one of the moving blocks 23 slide on the outer side of the slide bar 21, the moving frame 4 can also be limited.

[0035] Support rods 11 are fixedly installed around the bottom of the support frame 12, and a base plate 1 is fixedly installed at the bottom of each of the four support rods 11.

[0036] Limiting rods 45 are fixedly installed at both ends of one side of the clamping frame 44, and the limiting rods 45 are slidably connected to the inside of the side frame 42.

[0037] The bottom of the receiving bucket 3 is fixedly installed on the top of the base plate 1.

[0038] The outer side of the adjusting rod 43 is threaded, so it can be threaded inside the side frame 42 during use. The limiting rod 45 can also limit the clamping frame 44 to prevent rotation.

[0039] The working principle of the cemented carbide wet abrasive slurry screening device provided by this utility model is as follows:

[0040] When in use, place the filter bucket 5 containing the hard alloy wet abrasive slurry on the inner side of the moving frame 4, and make the bottom of the handle 51 abut against the top of the moving frame 4. Then the user rotates the adjusting rod 43, so that the adjusting rod 43 is threaded inside the side frame 42, thereby moving the two clamping frames 44 to one side of the filter bucket 5 to clamp and limit the filter bucket 5.

[0041] The user then starts the drive motor 22, which drives the reciprocating screw 25 to connect with the thread inside one of the moving blocks 23, thereby moving the moving block 23 back and forth. Then, the moving block 23 drives the sliding block 24 and the second toothed plate 41 to move, so that the top of the second toothed plate 41 and the first toothed plate 14 mesh, and then vibration is generated, which causes the moving frame 4 to move up and down. At this time, the sliding block 24 will slide up and down inside the moving block 23, so that the slurry flows into the inner side of the receiving bucket 3 for collection.

[0042] Compared with related technologies, the cemented carbide wet abrasive slurry screening device provided by this utility model has the following beneficial effects:

[0043] By rotating the adjusting rod 43, the clamping frame 44 is moved to one side of the filter barrel 5, thereby clamping and limiting the filter barrel 5 and preventing the side of the filter barrel 5 from colliding with the inner side of the moving frame 4 when it moves back and forth. Furthermore, by sliding the second toothed plate 41 on top of the first toothed plate 14, the moving frame 4 can vibrate up and down while it moves back and forth, thereby increasing the screening effect.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 4 Based on the first embodiment of this application which provides a screening device for wet abrasive slurry of cemented carbide, the second embodiment of this application proposes another screening device for wet abrasive slurry of cemented carbide. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the difference in the second embodiment of this application regarding the screening device for cemented carbide wet abrasive slurry is that rollers 6 are fixedly installed around the bottom of the base plate 1.

[0047] Threaded sleeves 61 are fixedly installed inside all four sides of the base plate 1, and threaded rods 62 are threadedly connected inside the threaded sleeves 61.

[0048] A rotating plate 64 is fixedly installed on the top of the threaded rod 62, and a pad 63 is rotatably connected to the bottom of the threaded rod 62.

[0049] The working principle of the cemented carbide wet abrasive slurry screening device provided by this utility model is as follows:

[0050] When in use, the user can roll the roller 6 on the ground to move the device, thereby increasing the device's mobility. After moving to the appropriate position, the user can rotate the rotating plate 64, causing the rotating plate 64 to drive the threaded rod 62 to make a threaded connection on the inner side of the threaded sleeve 61, thereby causing the pad 63 to move downwards, so that the pad 63 contacts the ground and supports and limits the base plate 1.

[0051] Compared with related technologies, the cemented carbide wet abrasive slurry screening device provided by this utility model has the following beneficial effects:

[0052] The roller 6, threaded sleeve 61, threaded rod 62, pad 63 and rotating plate 64 work together to allow the user to move the device by rolling the roller 6 on the ground, increasing the device's mobility. After moving to the appropriate position, the pad 63 can also contact the ground to support and limit the device.
