Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a crushing and grinding mechanism for potassium feldspar. Background Art

[0002] Potassium feldspar belongs to the monoclinic system and typically appears in colors ranging from flesh-red to yellow and white. Potassium feldspar is typically flesh-red, white, or gray and primarily includes orthoclase, microcline, and sanuclear feldspar. It has a low melting point, a long melting interval, and high melt viscosity.

[0003] Currently, potassium feldspar is usually used in powder form, but in reality, potassium feldspar is mostly in crystalline form. Therefore, potassium feldspar needs to be crushed and ground before it can be used.

[0004] Most of the existing devices for crushing potassium feldspar are crushers, which are mainly used to crush large pieces of crystalline potassium feldspar. The crushed potassium feldspar particles participate in the grinding process.

[0005] However, in practice, while most potassium feldspar grinding equipment is ball mills, which can significantly increase the fineness of potassium feldspar powder, existing crushers still produce large crystals (mostly with a particle size of over 1 cm). These crystals require a considerable amount of grinding time in the ball mill to produce potassium feldspar powder, resulting in a lengthy production process. Therefore, a potassium feldspar crushing and grinding mechanism was needed that could fully utilize the inherent brittleness of potassium feldspar and reduce the particle size of the crushed crystals.

[0009] Preferably, the driving member II includes a follower ring, which is provided with a plurality of follower grooves, and the distances between the two ends of each follower groove and the central axis of the follower ring are not equal, and the inner wall of each follower groove has a smooth transition. The side end of the follower ring is provided with a plurality of follower rods, and the plurality of follower rods correspond one-to-one to the plurality of pressure plates, and one end of each follower rod is rotatably connected to the inner side wall of the upper end of the corresponding pressure plate, and the other end of each follower rod is fixedly connected to a driven rod, and the central axis of the driven rod is parallel to the central axis of the follower ring, and the plurality of follower rods correspond one-to-one to the plurality of follower grooves, and the driven rods are inserted into the corresponding follower grooves.

A plurality of drive grooves are opened on the side end of the driven tube, and the upper and lower ends of the drive grooves are not in the same vertical plane, and a drive shaft is inserted in each of the drive grooves, and a drive ring is sleeved on the outer side of the driven tube, and the inner side wall of the drive ring is fixedly connected to a plurality of drive shafts, and the central axis of each drive shaft is perpendicular to the central axis of the corresponding drive ring.

[0011] Preferably, the drive ring is provided with a plurality of internal threaded holes in the upper and lower axial directions, and a lead screw is inserted into each of the internal threaded holes, and the lower end of the lead screw is rotatably connected to the positioning plate.

[0012] Preferably, the lead screw is a bidirectional lead screw, and a follower gear is coaxially fixedly connected to the outer side of the lower end of each lead screw, and multiple follower gears are meshingly connected.

At the same time, the presence of driving member II can drive the outer end of the pressure plate to change the distance between it and the inner wall of the outer shell, which can squeeze and crush the potassium feldspar between the pressure plate and the outer shell. Therefore, in practice, as the potassium feldspar continues to fall between the outer shell and the pressure plate, the potassium feldspar is squeezed and crushed by the pressure plate in the initial stage, and is continuously squeezed and crushed in the later stage, and is also subjected to the grinding effect caused by the relative movement between the pressure plate and the outer shell. Compared with the existing technology, this method fully utilizes the high brittleness of the crystal itself. The squeezing and crushing combined with the opposing forces can fully reduce the particle size of the crushed potassium feldspar. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] Please refer to Figure 1 A crushing and grinding mechanism for potassium feldspar includes an outer shell 2 with an open structure at the upper end. The upper end of the outer shell 2 is open, which is mainly to facilitate the addition of potassium feldspar into the inner part of the outer shell 2 by cooperating with relevant feeding equipment.

[0029] Therefore, the device is provided with a corresponding discharge chute below the outer shell 2 , so that in practice, after the potassium feldspar is processed by the corresponding crushing and grinding mechanism, it can be discharged from the outer shell 2 through the discharge chute.

[0030] What is different from the prior art devices is that Figure 1 、 Figure 2 、 Figure 3 As shown, a coaxial positioning plate 8 is provided inside the outer shell 2 , and a plurality of pressure plates 3 are provided between the positioning plate 8 and the outer shell 2 . Furthermore, the plurality of pressure plates 3 are equidistantly arranged around the central axis of the positioning plate 8 .

[0031] At the same time, a plurality of limit rods 11 are fixedly connected to the side end of the positioning plate 8, and the plurality of limit rods 11 correspond one-to-one to the plurality of pressure plates 3. This enables each limit rod 11 to be rotatably connected to the inner side wall of the lower end of the corresponding pressure plate 3 through the pin shaft 5, that is, a single pressure plate 3 can rotate around the central axis of the pin shaft 5.

[0032] Therefore, the device is coaxially fixed with a positioning rod 9 at the upper end of the positioning plate 8, and a driving component Ⅱ4 is provided at the upper end of the positioning rod 9. The upper end of the positioning rod 9 changes the distance between the upper side of the pressure plate 3 and the central axis of the positioning plate 8 through the driving component Ⅱ4. This can change the distance between the upper side of the pressure plate 3 and the central axis of the positioning plate 8 so that the pressure plate 3 rotates around the central axis of the pin shaft 5, thereby realizing the control of the inclination angle of the pressure plate 3.

[0033] It should be noted that, in practice, the gap between the outer end of the pressure plate 3 and the inner wall of the outer shell 2 can be changed by continuously changing the inclination angle of the pressure plate 3 back and forth, thereby squeezing and crushing the potassium feldspar located between the outer shell 2 and the pressure plate 3.

[0034] Furthermore, the present device is coaxially fixedly connected to a support rod 10 at the lower end of the positioning plate 8, and the outer shell 2 is sleeved on the outside of the support rod 10 and is rotatably connected to the support rod 10. At the same time, the present device is consistent with the prior art device. The present device is provided with a driving member I1 at the side end of the outer shell 2. The outer shell 2 is matched with the gear of the driving member I1 so that the outer shell 2 can rotate around the central axis of the positioning plate 8, that is, the outer shell 2 rotates relative to the pressure plate 3. This utilizes the relative movement between the two to realize the grinding of the potassium feldspar located between the outer shell 2 and the pressure plate 3, which can make the potassium feldspar processed by the present device have a higher grinding fineness.

[0035] Furthermore, the device is further provided with a plurality of grinding blocks 6 fixedly connected to the outer end of the pressure plate 3. The plurality of grinding blocks 6 are arranged in a rectangular array on the pressure plate 3. This allows the potassium feldspar located between the pressure plate 3 and the outer shell 2 to periodically feel different pressure changes due to the relative movement between the two, thereby utilizing the grinding blocks 6 to improve the grinding effect of the potassium feldspar material.

[0036] It should be noted that since the multiple pressure plates 3 continuously swing back and forth to change the distance between them and the inner wall of the outer shell 2, in order to avoid travel conflicts between adjacent pressure plates 3, the width of the upper end of the pressure plate 3 must be smaller than the width of the lower end. This can avoid travel conflicts between the upper ends of the multiple pressure plates 3 when the pressure plates 3 swing inward and the projection diameter formed by the upper ends of the multiple pressure plates 3 decreases.

[0037] Therefore, changes in the width of the upper and lower ends of the pressure plates 3 inevitably cause the width of the gaps between the upper and lower ends of adjacent pressure plates 3 to change due to their swinging position. Therefore, to prevent the crushed potassium feldspar fragments from entering the inner side of the pressure plates 3 through the gaps between adjacent potassium feldspar, this device installs an elastic net 7 between two adjacent pressure plates 3, and the elastic net 7 is fixedly connected to the adjacent pressure plates 3.

[0038] It should be noted that the thickness relationship between the elastic mesh 7 and the pressure plates 3 necessarily results in a gap between adjacent pressure plates 3. However, at this time, the potassium feldspar crushed material cannot enter the inner side of the pressure plates 3 through the gap, and the potassium feldspar crushed material now abuts the elastic mesh 7. However, correspondingly, due to the continuous relative motion between the pressure plates 3 and the outer shell 2, this relative motion exerts a horizontal thrust on the potassium feldspar. In addition, the continuous swinging of the pressure plates 3 and the reduction of the gap between adjacent pressure plates 3 also provide an extrusive force, i.e., a horizontal thrust, on the potassium feldspar. The elastic mesh 7 itself can also accumulate elastic potential energy. This approach ensures that, in practice, the potassium feldspar crushed material will not remain in the gap between adjacent pressure plates 3 for a long time, unable to be crushed.

[0039] Furthermore, since the upper ends of the multiple pressure plates 3 are also open structures, in order to prevent the stones from impacting the outer shell 2 and bouncing into the inner side of the pressure plates 3 during the filling process of the potassium feldspar raw material, the device constrains the projection of the pressure plates 3 on the vertical plane to be an arc structure, and the height of the concave section of the pressure plate 3 is greater than the height of the upper end surface of the outer shell 2.

[0040] Specifically, such as Figure 2 、 Figure 3 、 Figure 4 As shown, the driving component II4 includes a follower ring 402, and a plurality of follower grooves 403 are formed through the follower ring 402. The distances between the two ends of each follower groove 403 and the central axis of the follower ring 402 are different, and the inner wall of each follower groove 403 has a smooth transition.

[0041] At the same time, a plurality of follower rods 401 are provided at the side end of the follower ring 402, and the plurality of follower rods 401 correspond to the plurality of pressure plates 3 one by one. At this time, by constraining one end of the follower rod 401 to be rotatably connected to the inner side wall of the upper end of the corresponding pressure plate 3, the other end of each follower rod 401 is fixedly connected to a follower rod 404, and the central axis of the follower rod 404 is parallel to the central axis of the follower ring 402. The follower rod 404 can be inserted into the corresponding follower groove 403, so that during the rotation of the follower ring 402, the distance between the follower rod 404 and the central axis of the follower ring 402 is changed by utilizing the different abutment positions of the follower rod 404 and the follower groove 403, thereby realizing the change of the position of the follower rod 401 and then controlling the inclination angle of the pressure plate 3.

[0042] Furthermore, Figure 4 、 Figure 5As shown, in order to realize the continuous reciprocating rotation of the follower ring 402, that is, to realize the continuous reciprocating swing of the pressure plate 3 and continuously change the distance between the outer wall of the pressure plate 3 and the inner wall of the outer shell 2, the device is provided with a follower tube 405 on the outside of the positioning rod 9, and the follower tube 405 is coaxially connected to the positioning rod 9, and the follower tube 405 is located on the inner side of the follower ring 402, and the follower tube 405 is key-connected to the follower ring 402. At this time, the rotation of the driven tube 405 can drive the follower ring 402 to rotate.

[0043] Therefore, the device is provided with a plurality of driving grooves 410 on the side end of the driven tube 405 . The upper and lower ends of the driving grooves 410 are not located in the same vertical plane, and a driving shaft 411 is inserted into each of the driving grooves 410 .

[0044] At the same time, a driving ring 406 is sleeved on the outside of the driven tube 405, and the inner wall of the driving ring 406 is fixedly connected to multiple driving shafts 411, and the central axis of each driving shaft 411 is perpendicular to the central axis of the corresponding driving ring 406. At this time, as the driving ring 406 continuously performs reciprocating linear motion up and down, the driving shaft 411 and the driving groove 410 can be used to continuously drive the driven tube 405 to perform reciprocating rotation, thereby realizing the reciprocating rotation process of the follower ring 402.

[0045] It should be emphasized that the driven tube 405 is slidably connected to the follower ring 402 , which can avoid travel conflict between the follower rod 401 and the pressure plate 3 during the swinging process of the pressure plate 3 .

[0046] Specifically, such as Figure 5 As shown, the device has multiple upper and lower axial internal threaded holes running through the drive ring 406, and a screw 407 is inserted into each internal threaded hole. The lower end of the screw 407 is rotatably connected to the positioning plate 8. At this time, the rotation of the screw 407 can realize the up and down movement of the drive ring 406.

[0047] Furthermore, Figure 5 、 Figure 6 As shown, the lead screw 407 is a bidirectional lead screw 407. According to its own characteristics, the lead screw 407 can use two threads in opposite directions during its continuous rotation, in conjunction with transition sections set at the two thread ends, so that the components screwed thereto can continuously perform reciprocating linear motion along the direction of its central axis, thereby realizing the up and down reciprocating linear motion of the drive ring 406.

[0048] Furthermore, in this device, a follower gear 409 is coaxially fixedly connected to the outer side of the lower end of each screw 407, constraining the number of screws 407 to be an even number, and multiple follower gears 409 are engaged in transmission connection, which can ensure that multiple screws 407 rotate synchronously and ensure smooth operation of the drive ring 406.

[0049] At the same time, the device is also equipped with a drive motor 408 on one side of one of the follower gears 409. The drive motor 408 is fixedly connected to the positioning plate 8, and the output shaft of the drive motor 408 is coaxially fixedly connected to the drive gear 412. The drive gear 412 is meshed and transmission-connected with the adjacent follower gear 409.

[0050] Furthermore, the present device constrains the transmission ratio between the driving gear 412 and the follower gear 409 to be not equal to one, and the diameter of the driving gear 412 is smaller than the diameter of the follower gear 409. This, combined with the cooperation between the driving shaft 411 and the driving slot 410, can fully reduce the load pressure borne by the driving motor 408, ensuring that the potassium feldspar can be squeezed and crushed during the swinging process of the pressure plate 3.

[0051] During actual use, the utility model:

[0052] First, the operator turns on the drive motor 408 and the drive member I1. At this time, the pressure plate 3 continuously swings to change the distance between it and the inner wall of the outer shell 2, and the outer shell 2 continuously rotates in one direction.

[0053] Then, the operator tilts the potassium feldspar to the upper slope of the outer shell 2 through the corresponding filling equipment. At this time, the potassium feldspar slides down to the gap between the outer shell 2 and the pressure plate 3 under the influence of its own gravity;

[0054] Afterwards, the potassium feldspar that enters between the outer shell 2 and the pressure plate 3 falls and is crushed by the pressure plate 3;

[0055] Then, as the potassium feldspar continues to fall, the gap between the pressure plate 3 and the inner wall of the outer shell 2 gradually narrows, and the potassium feldspar abuts against the pressure plate 3 and the outer shell 2 at the same time. At this time, the potassium feldspar is squeezed by the pressure plate 3, and the potassium feldspar is subjected to the combined force of the outer shell 2 and the pressure plate 3;

[0056] Finally, the crushed and ground potassium feldspar is discharged through the discharge trough.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
