Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a vertical grinding mill for calcium hydroxide. Background Technology

[0002] Calcium hydroxide, as a core product in the deep processing of lime, is widely used in environmental desulfurization, sewage purification, chemical preparations, building coatings and other fields. In the actual application scenarios of vertical grinding mills for calcium hydroxide, whether it is grinding small batches of samples in the laboratory or small-scale processing in the workshop, the power supply cables of the equipment need to be frequently plugged in and unplugged and stored. Before grinding, the cables need to be unfolded and connected to the power supply. After the operation, the cables need to be stored to avoid them being scattered on the workbench. Utility Model Content

[0003] This utility model addresses the problem that during the idle period of a grinding mill, the connecting wires on its surface are scattered on the worktable, which leads to the connecting wires becoming tangled and damaged, affecting the normal use of the grinding mill the next time. Therefore, a vertical calcium hydroxide grinding mill is proposed.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a vertical calcium hydroxide grinding mill, comprising a grinding host, a power supply cable, a power plug, a top cover, control buttons, a grinding disc, and a winding device. One end of the power supply cable is fixedly connected to the lower side wall of the grinding host, and the other end is fixedly connected to the power plug. The grinding disc is coaxially arranged in the internal cavity of the grinding host, and its edge is spaced apart from the inner wall of the grinding host. The central axis of the grinding disc is driven by the driving mechanism of the grinding host and can rotate around its own axis. The top cover is fitted onto the top opening of the grinding host and engages with the top edge of the grinding host. The control buttons are embedded in the upper part of the front surface of the grinding host and are electrically connected to the internal control circuit of the grinding host. The winding device is fixedly arranged on the side wall of the grinding host and located above the power supply cable. The winding device includes a fixed base plate, two rotating shafts, two pressing plates, an adjusting screw, and a pressing rod. The fixed base plate is vertically fixed to the side wall of the grinding host. The plate surface is parallel to the side wall of the grinding machine. Two rotating shafts are spaced apart along the length of the fixed base plate, and their axes are perpendicular to the plate surface. One end of each rotating shaft is fixedly connected to the plate surface of the fixed base plate. Two clamping plates are respectively arranged corresponding to the two rotating shafts. One end of each clamping plate has a shaft hole, which is fitted around the outer circumference of the rotating shaft, allowing the clamping plate to rotate around the axis of the rotating shaft. A sliding groove is formed in the middle of each clamping plate along its length, and the sliding groove passes through both sides of the clamping plate. An adjusting screw is arranged along the width of the fixed base plate, with one end rotatably connected to the plate surface of the fixed base plate and the other end extending away from the fixed base plate. A threaded hole is formed in the middle of the pressing rod, and the threaded hole is threadedly engaged with the adjusting screw. Both ends of the pressing rod are respectively embedded in the sliding grooves of the two clamping plates and can slide along the extension direction of the sliding grooves. A fixing nut is also threadedly connected to the outer circumference of the adjusting screw. The fixing nut is located on the side of the pressing rod away from the fixed base plate and can abut against the end face of the pressing rod for limiting movement.

[0005] Preferably, a buffer plate is fixedly attached to the side of the pressing plate facing the power supply cable. The buffer plate is made of sponge material, and its thickness direction is perpendicular to the surface of the pressing plate.

[0006] Preferably, a knob block is coaxially fixed to the end of the adjusting screw away from the fixed base plate. Several anti-slip protrusions are spaced along the circumferential direction on the outer peripheral sidewall of the knob block. Rotating the knob block can drive the adjusting screw to rotate synchronously around its own axis.

[0007] Preferably, a torsion spring is fitted around the outer periphery of both rotating shafts. The torsion spring is located in the gap between the pressure plate and the fixed base plate. One end of the torsion spring is fixedly connected to the side wall of the rotating shaft, and the other end is fixedly connected to the side surface of the pressure plate facing the fixed base plate. When the pressing rod slides along the sliding groove and presses the pressure plate, the torsion spring is torsionally charged. When the pressing rod moves away from the fixed base plate, the torsion spring releases its elastic force, driving the pressure plate to reset and rotate around the axis of the rotating shaft away from the power supply cable.

[0008] Preferably, the inner side of the end of the pressing plate away from the rotation axis is provided with a snap-fit ​​groove, and a snap-fit ​​block is fixed on the plate surface of the fixed base plate at the position corresponding to the snap-fit ​​groove. When the pressing plate rotates around the rotation axis to fit the power supply cable, the snap-fit ​​block engages with the snap-fit ​​groove to restrict the rotation of the pressing plate.

[0009] Preferably, the device further includes a stabilizing device disposed between the bottom of the grinding host and the worktable. The stabilizing device includes a support base plate and two assembly blocks. The support base plate is horizontally disposed, and its bottom surface is fixedly connected to the table surface of the worktable. The top surface of the support base plate has symmetrically formed assembly grooves on both sides along its length. The cross-section of the assembly groove is "L"-shaped, and its opening faces the outside of the support base plate. The two assembly blocks are respectively fixed at the bottom of the grinding host near the two side edges. The shape of the assembly block is adapted to the inner wall of the assembly groove, and it can slide into the interior of the assembly groove along the opening direction of the assembly groove. After the assembly block slides into the bottom of the assembly groove, the grinding host is rotated so that the assembly block abuts against the "L"-shaped stepped surface of the assembly groove, thereby fixing the grinding host to the support base plate.

[0010] Preferably, anti-slip pads are fixedly attached to both side walls of the assembly block. The anti-slip pads are made of rubber. When the assembly block is engaged in the assembly groove, the anti-slip pads are tightly attached to the inner wall of the assembly groove, increasing the friction between the assembly block and the assembly groove.

[0011] Preferably, a calibration groove is provided in the center area of ​​the top surface of the support plate, and a calibration block is vertically fixed at the center of the bottom of the grinding host. When the grinding host is placed on the support plate, the calibration block and the calibration groove are coaxially inserted to pre-position the installation position of the grinding host.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] By setting up a winding device, the power supply cable can be orderly wound between the pressure plates. With the help of the adjusting screw driving the extrusion rod, the pressure plate is pushed to firmly limit the cable, avoiding the problems of knotting and wear caused by the cable being scattered on the worktable when not in use. At the same time, the buffer plate on the pressure plate is made of sponge material, which can protect the cable insulation layer during the extrusion and limiting process, reduce cable damage caused by extrusion pressure, and extend the service life of the power supply cable. Moreover, when using it again, you only need to loosen the fixing nut and use the torsion spring to drive the pressure plate to reset, which can quickly unwind the cable, improve the convenience of cable access, and ensure the normal power supply of the grinding mill in the future.

[0019] Reference Figure 1-4As shown, this embodiment discloses a vertical calcium hydroxide grinding mill. The grinding host 1 is generally in the shape of a vertical cylinder or square column, with an internal cavity for accommodating the calcium hydroxide material to be ground. The top of the cavity has an opening for feeding material and removing the ground powder. The bottom of the grinding host 1 has a built-in drive mechanism, specifically a motor, with the motor's output shaft extending vertically upwards. One end of the power cable 2 is fixed to the lower side wall of the grinding host 1 by an insulating fixing sleeve or metal clip, avoiding the operating area of ​​the grinding host 1. The other end of the power cable 2 is integrally formed with the power plug 3 or fixedly connected by a crimping method. The power plug 3 can be adapted to common AC sockets to obtain power. The grinding disc 6 is made of metal, and its surface may have several raised grinding teeth. The grinding disc 6 is coaxially arranged in the internal cavity of the grinding host 1, with a gap maintained between the edge of the disc and the inner wall of the grinding host 1 for material grinding. The central shaft of the grinding disc 6 is connected to the output shaft of the drive mechanism at the bottom of the grinding host 1 via a coupling. When the drive mechanism is started, the grinding disc 6 can rotate stably around its own axis. The top cover 4 is a cover structure adapted to the top opening of the grinding host 1. The edge of the top cover has an annular protrusion, and the top edge of the grinding host 1 has a corresponding annular groove. When the top cover 4 is closed at the top opening of the grinding host 1, the protrusion of the top cover edge can be engaged into the groove on the top of the host, achieving a stable fit between the top cover and the host and facilitating manual opening and closing for loading and unloading calcium hydroxide material. The control button 5 is a push-button mechanical button, and its number can be set to 2-3 according to functional requirements, corresponding to start, stop and speed adjustment functions respectively. The control button 5 is embedded in the upper part of the front surface of the grinding host 1 and protrudes from the surface of the host, making it convenient for the operator to press. The control button 5 is electrically connected to the internal control circuit of the grinding host 1 through internal wires. Pressing the button can trigger the circuit to control the running status of the drive mechanism. The winding device is fixedly installed on the side wall of the grinding host 1 and directly above the power supply cable 2, ensuring that the power supply cable 2 hangs down naturally and fits against the winding device when winding. The fixing base plate 7 in the winding device is made of metal plate, and one side of it is vertically fixed to the side wall of the grinding host 1 by bolts or welding. The surface of the fixing base plate 7 is parallel and flat to the side wall of the grinding host 1. The two rotating shafts 8 are both metal round shafts, which are symmetrically spaced on the left and right along the length of the fixing base plate 7. One end of the rotating shaft 8 is welded and fixed perpendicularly to the surface of the fixing base plate 7, and the other end is provided with a circular limit cap. The diameter of the limit cap is larger than the diameter of the rotating shaft 8, which can prevent the pressure plate 9 sleeved on the rotating shaft 8 from falling off the shaft end.Both clamping plates 9 are elongated metal plates, with a circular shaft hole at one end that matches the diameter of the rotating shaft 8. After the shaft hole is fitted onto the outer circumference of the rotating shaft 8, the clamping plate 9 can rotate flexibly around the axis of the rotating shaft 8. A long, narrow sliding groove 10 is formed in the middle of the clamping plate 9 along its length, penetrating the plate surface. The width of the sliding groove 10 matches the diameter of the subsequent extrusion rod 12, ensuring that the extrusion rod 12 can slide smoothly along the extension direction of the sliding groove 10. The adjusting screw 11 is an externally threaded metal rod, which is horizontally set along the width direction of the fixed base plate 7. A bearing seat with a bearing is welded to the fixed base plate 7 at the position corresponding to the adjusting screw 11. One end of the adjusting screw 11 is installed in the bearing seat through the bearing, so that the adjusting screw 11 can rotate around its own axis without axial movement. The other end of the adjusting screw 11 extends horizontally away from the fixed base plate 7 for easy rotation by the operator. The pressing rod 12 is a round metal rod with an internal threaded hole along its axial direction in its middle section, which is adapted to the external thread of the adjusting screw 11. After the adjusting screw 11 passes through the threaded hole, it forms a threaded engagement with the pressing rod 12. Both ends of the pressing rod 12 are provided with circular bosses, the diameter of which is larger than the width of the sliding groove 10. When both ends of the pressing rod 12 are embedded in the sliding grooves 10 of the two clamping plates 9, the bosses can prevent the pressing rod 12 from falling out of the sliding grooves 10. The fixing nut 13 is a standard nut adapted to the external thread of the adjusting screw 11. Its thread is connected to the outer circumference of the adjusting screw 11 and is located on the side of the pressing rod 12 away from the fixed base plate 7. When the fixing nut 13 is tightened towards the pressing rod 12, its end face can abut against the end face of the pressing rod 12, thereby restricting the rotation of the adjusting screw 11 and keeping the position of the pressing rod 12 on the adjusting screw 11 stable. A buffer plate 15 is glued to the side of the clamping plate 9 facing the power supply cable 2 with epoxy resin adhesive. The buffer plate 15 is made of high-density sponge material, and its coverage area corresponds exactly to the area in contact between the clamping plate 9 and the power supply cable 2. The thickness of the buffer plate 15 is uniform, which can prevent the cable insulation layer from being worn when the clamping plate 9 squeezes the cable. A knob block 14 is coaxially fixed to the end of the adjusting screw 11 away from the fixed base plate 7 by welding. The knob block 14 is made of plastic or rubber and is cylindrical or hexagonal in shape, which is convenient for the operator to pinch and turn. Several hemispherical anti-slip protrusions are evenly spaced along the circumference on the outer side wall of the knob block 14. The anti-slip protrusions can increase the friction between the hand and the knob block 14 and prevent slippage when turning. Both rotating shafts 8 are fitted with torsion springs 18 on their outer circumference. The torsion springs 18 are located in the gap between the pressure plate 9 and the fixed base plate 7. One end of the torsion spring 18 is fixedly connected to the side wall of the rotating shaft 8 by means of hook or welding, and the other end is also fixedly connected to the side of the pressure plate 9 facing the fixed base plate 7. In the natural state, the torsion spring 18 can keep the pressure plate 9 in an open state with a certain angle to the fixed base plate 7. When the pressure plate 9 is squeezed and rotated, the torsion spring 18 will be twisted and store elastic force.The inner side of the clamping plate 9, away from the rotating shaft 8, has a latching groove 17. The latching groove 17 is a square or cylindrical groove that matches the latching block 16. The latching block 16 is a metal protrusion that is fixed to the fixed base plate 7 at the position corresponding to the latching groove 17 by welding or bolts. When the clamping plate 9 rotates around the rotating shaft 8 to fit the power supply cable 2, the latching block 16 can be precisely engaged in the latching groove 17, further restricting the rotation of the clamping plate 9 to maintain the clamping state of the cable. The bottom of the grinding host 1 is also provided with a stabilizing device. This stabilizing device is set between the grinding host 1 and the worktable to improve the stability of the equipment. The support plate 19 in the stabilizing device is a metal square plate, and its bottom surface is fixed to the worktable surface by expansion bolts or ordinary bolts. The top surface of the support plate 19 is kept horizontal to ensure that the grinding host 1 is placed stably. The support plate 19 has symmetrically formed L-shaped mounting grooves 20 on both sides of its length. The horizontal section of the mounting groove 20 faces the outside of the support plate 19, and the vertical section extends downward with a stepped bottom. The mounting block 21 is a metal block that matches the shape of the mounting groove 20. It is fixed to the bottom of the grinding host 1 near the two side edges by welding. The height of the mounting block 21 matches the depth of the vertical section of the mounting groove 20. Anti-slip pads 22 are glued to both sides of the surface of the mounting block 21. The anti-slip pads 22 are made of oil-resistant and aging-resistant rubber material with a thickness of 1-2mm. When the mounting block 21 is engaged in the mounting groove 20, the anti-slip pads 22 will fit tightly against the inner wall of the mounting groove 20 and produce a certain elastic deformation, thereby increasing the friction between the mounting block 21 and the mounting groove 20. A circular calibration groove 23 is provided in the center area of ​​the top surface of the support plate 19. The depth of the calibration groove 23 is moderate. A cylindrical calibration block 24 is vertically fixed at the bottom center of the grinding host 1 by welding. The diameter of the calibration block 24 is adapted to the inner diameter of the calibration groove 23. When the grinding host 1 is placed on the support plate 19, the calibration block 24 can be coaxially inserted into the calibration groove 23 to realize the quick pre-positioning of the installation position of the grinding host 1.

[0020] Working Principle: When grinding calcium hydroxide, first manually lift the top cover 4 of the equipment upwards, allowing the protruding edge of the top cover to disengage from the slot on the top of the grinding host 1. Place the calcium hydroxide lumps or granules to be ground into the internal cavity through the opening at the top of the host. After placement, close the top cover 4, ensuring the protruding edge is engaged in the slot. Then, press the start button on the control button 5 on the front of the grinding host 1. Control button 5 triggers the internal control circuit via internal wires, energizing the motor of the bottom drive mechanism. The motor output shaft drives the grinding disc 6 to rotate around its own axis via a coupling. The rotating grinding disc 6 utilizes the gap between the grinding teeth on its surface and the inner wall of the host to shear, impact, and grind the calcium hydroxide material in the cavity. Adjustments can be made as needed. The grinding fineness can be adjusted by pressing the speed control button 5 to change the rotation speed of the grinding disc 6 via the circuit. After grinding is complete, press the stop button to cut off the motor power. Then, open the top cover 4 of the equipment again to remove the calcium hydroxide powder from the cavity. When storing the power cable 2, first unplug the power plug 3 from the socket. Hold the cable and wind it along the area between the two clamping plates 9 of the winding device. After winding until there are no loose parts of the cable, pinch the knob block 14 and turn it clockwise. The knob block 14 drives the adjusting screw 11 to rotate around its own axis. Since the adjusting screw 11 is threaded with the extrusion rod 12 and the two ends of the extrusion rod 12 are restricted in the sliding groove 10 of the clamping plate 9 by the bosses, the rotation of the adjusting screw 11 will push the extrusion rod 12 along the edge of the clamping plate 9. As the pressing rod 12 moves closer to the fixed base plate 7, it exerts a radial thrust on the pressing plate 9 during its sliding motion within the sliding groove 10. This causes the two pressing plates 9 to rotate around their respective rotation axes 8 towards each other. At this time, the torsion spring 18 on the rotation axis 8 is twisted and stores elastic force until the buffer guard plate 15 on the pressing plate 9 is in close contact with the wound cable. Simultaneously, the snap-fit ​​groove 17 at the free end of the pressing plate 9 engages with the snap-fit ​​block 16 on the fixed base plate 7. Finally, the fixing nut 13 is tightened clockwise so that the end face of the fixing nut 13 presses against the pressing rod 12 to prevent the adjusting screw 11 from loosening, thus achieving stable cable winding. When the mill needs to be used again, first loosen the fixing nut 13 counterclockwise to disengage it from the end face of the pressing rod 12, and then turn the knob counterclockwise. Block 14 drives the adjusting screw 11 to rotate in the opposite direction, the pressing rod 12 moves away from the fixed base plate 7, the thrust on the pressing plate 9 disappears, the torsion spring 18 releases the stored elastic force, and drives the pressing plate 9 to rotate back around the rotating axis 8 in a direction away from each other, the snap-lock slot 17 disengages from the snap-lock block 16, at this time the cable can be unwound from the winding device and the power plug 3 can be inserted into the socket. When installing the grinding mill, first fix the support plate 19 to the preset position on the worktable with bolts, then align the calibration block 24 at the bottom of the grinding host 1 with the calibration groove 23 on the top surface of the support plate 19 and slowly lower it so that the calibration block 24 is inserted into the calibration groove 23 to achieve the pre-position. At this time, the assembly blocks 21 on both sides of the bottom of the host are exactly aligned with the opening of the assembly groove 20 of the support plate 19.Push the grinding host 1 to slide the assembly block 21 into the horizontal section of the assembly groove 20. Then press the host down and rotate it 90 degrees clockwise so that the assembly block 21 is engaged with the stepped surface of the vertical section of the assembly groove 20. The anti-slip rubber pads 22 on both sides of the assembly block 21 are in close contact with the inner wall of the assembly groove 20 to generate friction, preventing the position from shifting due to vibration caused by the rotation of the grinding disc 6 during the operation of the grinding mill, thus ensuring stable operation of the equipment.
