Description

Technical Field

[0001] This utility model relates to lime processing, and more specifically, to a grinding device for lime processing. Background Technology

[0002] Lime is an air-hardening inorganic cementing material with calcium oxide as its main component, obtained by calcining raw materials such as limestone, dolomite, or chalk. It is one of the earliest cementing materials used by mankind and is widely used in building decoration.

[0003] In the process of processing lime, grinding equipment is inevitably used. However, existing grinding equipment does not pre-treat the lime, resulting in the lime being ground directly, which leads to insufficient grinding and poor grinding effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a grinding device for lime processing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A grinding device for lime processing includes a housing. A feed hopper is fixedly connected to the top of the housing and communicates with the interior of the housing. A grinding assembly is disposed inside the housing. The grinding assembly includes a first grinding shaft rotatably connected to the housing, a first grinding roller sleeved on the first grinding shaft, a second grinding shaft rotatably connected to the end of the housing away from the first grinding shaft, a second grinding roller sleeved on the second grinding shaft, and a first crushing shaft rotatably connected to the top of the housing away from the first grinding shaft, a first crushing roller sleeved on the first crushing shaft, and one end of the first crushing shaft extending into the housing. The outer part of the housing is fixedly connected to the first crushing gear. Inside the housing, a second crushing shaft is rotatably connected to the top of the housing away from the second grinding shaft. A second crushing roller is fitted over the second crushing shaft. One end of the second crushing shaft extends out of the housing and is fixedly connected to the second crushing gear. The second crushing gear meshes with the first crushing gear. The other end of the second crushing shaft extends out of the housing and is connected to the output end of the crushing motor. A filter assembly is provided at the bottom of the housing away from the grinding assembly. A pull-out groove is provided on the bottom of the inner surface of the housing. One end of the pull-out groove extends out of the housing and is slidably connected to the pull-out box.

[0008] Furthermore, in order to filter the ground lime, the filter assembly includes a filter shaft rotatably connected to the housing, cams symmetrically welded on the filter shaft, sliding grooves formed at both ends of the inner surface of the housing away from the top of the filter shaft, filter plates slidably connected between the sliding grooves, and fixed crossbars fixedly installed at both ends of the inner surface of the housing away from the top of the sliding grooves, the fixed crossbars being connected to the filter plates by springs.

[0009] Furthermore, in order to allow the first and second grinding shafts to rotate synchronously, one end of the first grinding shaft extends outside the housing and is fixedly connected to the first grinding gear, and one end of the second grinding shaft extends outside the housing and is fixedly connected to the second grinding gear, wherein the second grinding gear meshes with the first grinding gear.

[0010] Furthermore, in order to facilitate the rotation of the filter shaft with the first grinding shaft, the other end of the first grinding shaft extends out of the housing and is fixedly connected to the first transmission wheel. The filter shaft extends out of the housing and is fixedly connected to the second transmission wheel. The second transmission wheel is connected to the first transmission wheel via a transmission belt.

[0011] Furthermore, in order to rotate the second grinding shaft, the other end of the second grinding shaft extends out of the housing and is connected to the output end of the grinding motor.

[0012] Furthermore, to facilitate human control, a controller is fixedly installed on one side of the outer surface of the box, and the controller is electrically connected to the grinding motor and the crushing motor.

[0013] Furthermore, to prevent lime from flowing out between the crushing roller and the inner wall of the box, inclined plates are symmetrically welded to one end of the inner surface of the box near the feed hopper.

[0014] The beneficial effects of this utility model are as follows:

[0015] Lime enters the chamber through the feed hopper. At this time, the controller activates the crushing motor and the grinding motor simultaneously. The crushing motor drives the second crushing shaft to rotate, causing the second crushing roller and the second crushing gear to rotate. Through the meshing of the second crushing gear and the first crushing gear, the first crushing shaft rotates within the chamber, causing the first crushing roller to rotate accordingly. The rotation of the first and second crushing rollers pre-treats the lime. The pre-treated lime then moves towards the grinding assembly. The grinding motor drives the second grinding shaft to rotate, causing the second grinding roller and the second grinding gear to rotate. Through the meshing of the second and first grinding gears, the first grinding shaft rotates within the chamber, causing the first grinding roller to rotate accordingly. The rotation of the first and second grinding rollers grinds the pre-treated lime, making the lime grinding more thorough and finer, further improving the lime grinding effect.

[0016] The rotation of the first grinding shaft causes the first transmission wheel to move synchronously, and under the action of the transmission belt, the filter shaft rotates synchronously with the second transmission wheel. The rotation of the filter shaft causes the cam to rotate accordingly. Under the action of the spring elasticity, the filter plate is always in contact with the cam. The rotation of the cam causes the filter plate to slide in the sliding groove. With the cooperation of the spring and the cam, the filter plate slides back and forth in the sliding groove, which can filter the ground lime, further improve the quality of lime, and at the same time prevent the filter plate from clogging. The operation of the grinding motor can indirectly cause the filter shaft to rotate, further reducing the energy loss of the grinding motor. At the same time, the grinding device plays an energy-saving and environmentally friendly role. Attached Figure Description

One end of the first crushing shaft 4 extends outside the housing 1 and is connected to the first crushing roller 5. Gear 6 is fixedly connected. A second crushing shaft 8 is rotatably connected to the top of the cavity away from the second grinding shaft 15. A second crushing roller 9 is sleeved on the second crushing shaft 8. One end of the second crushing shaft 8 extends outside the housing 1 and is fixedly connected to the second crushing gear 10. The second crushing gear 10 meshes with the first crushing gear 6. The other end of the second crushing shaft 8 extends outside the housing 1 and is connected to the output end of the crushing motor 7. The crushing motor 7 is fixedly installed outside the housing 1 and electrically connected to the controller 29. A filter assembly is provided at the bottom of the cavity away from the grinding assembly. A pull-out groove 27 is opened on the bottom of the inner surface of the cavity.

Through the engagement of the second grinding gear 17 with the first grinding gear 13, the first grinding shaft 11 rotates within the housing 1, and the first grinding roller 12 rotates accordingly.The rotation of the first grinding roller 12 and the second grinding roller 16 grinds the pretreated lime, making the lime more thoroughly ground and finer, thus further improving the grinding effect. Example 2:

[0029] Please see Figures 1-4 The filter assembly includes a filter shaft 21 rotatably connected within a cavity. Cams 22 are symmetrically welded onto the filter shaft 21. Sliding grooves 23 are formed at both ends of the inner surface of the cavity, away from the top of the filter shaft 21. Filter plates 24 are slidably connected between the sliding grooves 23. Fixed crossbars 25 are fixedly installed at both ends of the inner surface of the housing 1, away from the top of the sliding grooves 23. The fixed crossbars 25 are connected to the filter plates 24 via springs 26, which have a certain elasticity. The filter shaft 21 extends outside the housing 1 and is fixedly connected to a second transmission wheel 20. The second transmission wheel 20 is connected to a first transmission wheel 18 via a transmission belt 19. The rotation of the first grinding shaft 11 causes the first transmission wheel 18 to move synchronously. Under the action of the drive belt 19, the filter shaft 21 rotates synchronously with the second transmission wheel 20. The rotation of the filter shaft 21 causes the cam 22 to rotate accordingly. Under the elastic action of the spring 26, the filter plate 24 is always in contact with the cam 22. The rotation of the cam 22 causes the filter plate 24 to slide in the sliding groove 23. With the cooperation of the spring 26 and the cam 22, the filter plate 24 slides back and forth in the sliding groove 23, which can filter the ground lime and further improve the quality of the lime. At the same time, it avoids the filter plate 24 from clogging. The operation of the grinding motor 14 can indirectly cause the filter shaft 21 to rotate, further reducing the energy loss of the grinding motor 14. At the same time, the grinding device plays an energy-saving and environmentally friendly role.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical application, firstly, lime enters the housing 1 through the feed hopper 2. Secondly, the controller 29 simultaneously operates the crushing motor 7 and the grinding motor 14.

Through the meshing of the second grinding gear 17 with the first grinding gear 13, the first grinding shaft 11 rotates within the housing 1, causing the first grinding roller 12 to rotate accordingly. 2. The rotation of the second grinding roller 16 grinds the pretreated lime, making the lime more thoroughly ground. Then, the ground lime moves to the filter assembly. At this time, the rotation of the first grinding shaft 11 causes the first transmission wheel 18 to move synchronously. Under the action of the transmission belt 19, the filter shaft 21 rotates synchronously with the second transmission wheel 20. The rotation of the filter shaft 21 causes the cam 22 to rotate accordingly. Under the elastic action of the spring 26, the filter plate 24 is always in contact with the cam 22.
