Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, and in particular to a screening device for calcium oxide. Background Technology
[0002] The screening device is used to screen calcium oxide particles of different sizes. The screening device consists of a base frame, telescopic rod, screening box, screening screen, mounting plate, polarization motor, and eccentric block. When using the screening device, the worker pours calcium oxide into the screening screen on the screening box. At the same time, the polarization motor drives the eccentric block to rotate, causing the screening box to shake, which in turn shakes the calcium oxide. After being screened by the screening screen, calcium oxide particles of different sizes are screened.
[0003] In their daily work, the inventors discovered that when using the screening device, calcium oxide easily absorbs water, causing calcium oxide particles to clump together. This prevents calcium oxide particles that could normally pass through the screening mesh from being screened, potentially affecting the quality of the screened calcium oxide. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in actual use, calcium oxide easily absorbs water, causing calcium oxide particles to easily clump together, thus preventing calcium oxide particles that could pass through the screening mesh from being screened, which may affect the quality of screened calcium oxide. Therefore, this invention proposes a screening device for calcium oxide.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for calcium oxide, comprising a base frame, a telescopic rod rotatably connected to the upper end of the base frame, a screening box rotatably connected to the other end of the telescopic rod, a first spring fixedly connected between the screening box and the base frame, an mounting plate fixedly connected to the upper end of the screening box, a fixing plate provided at the upper end of the mounting plate, a polarization motor mounted at the upper end of the fixing plate, an eccentric block fixedly connected to the output end of the polarization motor, an auxiliary installation assembly provided between the fixing plate and the mounting plate, a screening mesh fixedly connected to the inner wall of the screening box, a dispersing assembly provided on the inner wall of the screening box, the dispersing assembly comprising a long rod fixedly connected to the inner wall of the screening box, a plurality of evenly distributed blocking rods fixedly connected to the lower end of the long rod, and a dispersing rod provided between two blocking rods.
[0006] The effect achieved by the above components is as follows: by setting up a dispersing component, after the calcium oxide material is put into the screening screen, the polarization motor is started at the same time to drive the eccentric block to rotate. The agglomerated calcium oxide material is blocked by two blocking rods. Through the drive mechanism, the dispersing rod rotates and knocks on the agglomerated calcium oxide material to disperse it. Then it passes between the dispersing rod and the blocking rod and is screened. This can achieve the effect of avoiding the impact of screening quality on the agglomerated calcium oxide material that cannot be screened.
[0007] Preferably, the right end of the screening box is provided with a rotating rod that is rotatably connected by a bearing. The rotating rod and the long rod are rotatably connected by the bearing, and the dispersing rod is fixed to the rotating rod.
[0008] The effect achieved by the above components is that the rotating rod rotates, causing the disintegrating rod to rotate.
[0009] Preferably, a first half gear is fixedly connected to the right end of the rotating rod, and a second half gear is meshed with the lower end of the first half gear.
[0010] The effect achieved by the above components is that the rotation of the second half gear causes the rotation of the first half gear, which in turn causes the rotating rod to rotate.
[0011] Preferably, a mounting frame is fixedly connected to the right end of the screening box, and a drive motor is mounted on one end of the mounting frame. The output end of the drive motor is fixed to the second half gear.
[0012] The effect achieved by the above components is to start the drive motor on the mounting bracket, causing the second half gear to rotate.
[0013] Preferably, the blocking rod has cut surfaces on both sides.
[0014] The effect achieved by the above components is that by setting the cut surface, the blocking rod is prevented from blocking the material from slipping, and the dispersing rod can also have a cut surface.
[0015] Preferably, a torsion spring is fixedly connected to the back of the first half gear, and the other end of the torsion spring is fixed to the screening box.
[0016] The effect achieved by the above components is as follows: the second half gear drives the first half gear to rotate. After the second half gear rotates to the toothless part, the torsion spring resets, causing the first half gear to reset. Then the second half gear rotates to the toothed part and continues to drive the first half gear to rotate.
[0017] Preferably, the auxiliary installation component includes auxiliary blocks fixedly connected to both ends of the fixed plate, with a plug inserted into the upper end of the auxiliary block, the plug inserted into the installation plate, and the arc surface of the plug having a protrusion.
[0018] The effect achieved by the above components is as follows: when it is necessary to install the polarization motor onto the mounting plate, drag the fixing plate so that the mounting holes on the fixing plate are aligned with the mounting holes on the mounting plate, then drag the insertion rod to insert it into the mounting plate, thereby limiting the fixing plate, and then screw the bolt into the mounting hole to fix it, thereby assisting in the installation of the polarization motor onto the mounting plate.
[0019] Preferably, one end of the insertion rod is fixedly connected to a second spring, and the other end of the second spring is fixed to the auxiliary block.
[0020] The effect achieved by the above components is that by setting a second spring, the insertion rod is pulled and its position is limited.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting up a dispersing component, after the calcium oxide material is placed on the screening screen, the polarization motor is simultaneously activated, causing the eccentric block to rotate. The agglomerated calcium oxide material is blocked by two blocking rods. Through the driving mechanism, the dispersing rod rotates and strikes the agglomerated calcium oxide material to disperse it. The material then passes between the dispersing rod and the blocking rod and is then screened. This method aims to minimize the impact of agglomerated calcium oxide material on screening quality. It also solves the problem that calcium oxide easily absorbs water, causing calcium oxide particles to easily agglomerate, thus preventing calcium oxide particles that could pass through the screening mesh from being screened and potentially affecting the screening quality.

[0028] Reference Figure 1 and Figure 2As shown, this utility model provides a technical solution: a screening device for calcium oxide includes a base frame 1, a telescopic rod 5 rotatably connected to the upper end of the base frame 1, a screening box 4 rotatably connected to the other end of the telescopic rod 5, a first spring 6 fixedly connected between the screening box 4 and the base frame 1, an mounting plate 7 fixedly connected to the upper end of the screening box 4, a fixing plate 11 provided at the upper end of the mounting plate 7, a polarization motor 8 installed at the upper end of the fixing plate 11, an eccentric block 9 fixedly connected to the output end of the polarization motor 8, an auxiliary installation component 3 provided between the fixing plate 11 and the mounting plate 7, a screening mesh 10 fixedly connected to the inner wall of the screening box 4, and a dispersing component 2 provided on the inner wall of the screening box 4.
[0029] The following section will explain the specific settings and functions of the disassembly component 2 and the auxiliary installation component 3.
[0030] Reference Figure 3 and Figure 4 As shown in this embodiment: the dispersing component 2 includes a long rod 21 fixedly connected to the inner wall of the screening box 4. The lower end of the long rod 21 is fixedly connected to a plurality of evenly distributed blocking rods 22. A dispersing rod 23 is arranged between two blocking rods 22. By setting the dispersing component 2, after the calcium oxide material is put into the screening screen 10, the polarization motor 8 is started at the same time, which drives the eccentric block 9 to rotate. The agglomerated calcium oxide material is blocked by the two blocking rods 22. Through the driving mechanism, the dispersing rod 23 rotates and knocks on the agglomerated calcium oxide material to disperse it. Then it passes between the dispersing rod 23 and the blocking rod 22 and is screened. This achieves the effect of avoiding the screening quality being affected by the agglomerated calcium oxide material not being screened. The right end of the screening box 4 is provided with a rotating rod 27 rotatably connected by a bearing. The rotating rod 27 is rotatably connected to the long rod 21 by a bearing. The dispersing rod 23 is fixed to the rotating rod 27. The rotating rod 27 rotates, causing the dispersing rod 23 to rotate. A first half-gear 28 is fixedly connected to the right end of the rotating rod 27. A second half-gear 29 is meshed with the lower end of the first half-gear 28. When the second half-gear 29 rotates, the first half-gear 28 rotates, causing the rotating rod 27 to rotate. A mounting bracket 25 is fixedly connected to the right end of the screening box 4. A drive motor 26 is mounted on one end of the mounting bracket 25. The output end of the drive motor 26 is fixed to the second half-gear 29. When the drive motor 26 on the mounting bracket 25 is started, the second half-gear 29 rotates, and the two sides of the blocking rod 22 open. A cutting surface 24 is provided to prevent the blocking rod 22 from blocking the material from sliding down. The dispersing rod 23 can also have a cutting surface 24. A torsion spring 210 is fixedly connected to the back of the first half gear 28. The other end of the torsion spring 210 is fixed to the screening box 4. The second half gear 29 drives the first half gear 28 to rotate. After the second half gear 29 rotates to the toothless part, the torsion spring 210 resets, so that the first half gear 28 resets. Then the second half gear 29 rotates to the toothed part and continues to drive the first half gear 28 to rotate.
[0031] Reference Figure 2 As shown in this embodiment: the auxiliary installation component 3 includes auxiliary blocks 31 fixedly connected to both ends of the fixed plate 11. A rod 32 is inserted into the upper end of the auxiliary block 31 and inserted into the mounting plate 7. The rod 32 has a protrusion on its arc surface. When the auxiliary polarization motor 8 needs to be installed on the mounting plate 7, the fixed plate 11 is dragged so that the mounting hole on the fixed plate 11 is aligned with the mounting hole on the mounting plate 7. Then the rod 32 is dragged so that it is inserted into the mounting plate 7, thereby limiting the fixed plate 11. Then the bolt is screwed into the mounting hole for fixation, thereby allowing the auxiliary polarization motor 8 to be installed on the mounting plate 7. A second spring 33 is fixedly connected to one end of the rod 32. The other end of the second spring 33 is fixed to the auxiliary block 31. By setting the second spring 33, the rod 32 is pulled and the rod 32 is assisted in limiting its position.
[0032] Working principle:
[0033] When using the screening device, the worker pours calcium oxide into the screening screen 10 on the screening box 4. The screening box 4 is tilted, and the polarization motor 8 drives the eccentric block 9 to rotate, causing the screening box 4 to shake, which in turn causes the calcium oxide to shake and pass through the screening screen 10 to screen calcium oxide particles of different sizes. After the calcium oxide material is placed on the screening screen 10, the polarization motor 8 is started, causing the eccentric block 9 to rotate. The agglomerated calcium oxide material is blocked by two blocking rods 22. The drive motor 26 on the mounting frame 25 is started, causing the second half gear 29 to rotate, which in turn causes the first half gear 28 to rotate, which in turn causes the rotating rod 27 to rotate, which in turn causes the dispersing rod 23 to rotate, striking the agglomerated calcium oxide material to break it up. The material then passes between the dispersing rod 23 and the blocking rod 22 and is then screened, thus minimizing the impact of agglomerated calcium oxide material not being screened. To improve the screening quality, a cut surface 24 is provided to prevent the blocking rod 22 from blocking the material from slipping. The dispersing rod 23 can also have a cut surface 24. The second half gear 29 drives the first half gear 28 to rotate. After the second half gear 29 rotates to the toothless part, the torsion spring 210 resets, causing the first half gear 28 to reset. Then, the second half gear 29 rotates to the toothed part and continues to drive the first half gear 28 to rotate. When it is necessary to install the auxiliary polarization motor 8 onto the mounting plate 7, the fixing plate 11 is dragged so that the mounting hole on the fixing plate 11 is aligned with the mounting hole on the mounting plate 7. Then, the insertion rod 32 is dragged so that it is inserted into the auxiliary block 31 and the mounting plate 7, thereby limiting the fixing plate 11. Then, bolts are screwed into the mounting hole to fix it, thereby allowing the auxiliary polarization motor 8 to be installed onto the mounting plate 7. By providing a second spring 33, the insertion rod 32 is pulled and its position is limited.
