Description

Technical Field

[0001] The utility model relates to the technical field of stone crushing and processing, in particular to a fine stone crushing device. Background Technique

[0002] In industries such as mining, construction, and road construction, stones are often used. The process of stone crushing is usually mechanical. Stone mining generally targets large rocks. After the rocks are broken by blasting, the rocks form large stones of different sizes. After the large stones are crushed by a jaw crusher, the particle size of the stones becomes smaller. Finally, the stones are further processed by a fine crushing device to obtain fine-grained stones, which can be used as raw materials for concrete mortar.

[0003] At present, a ball mill is often used to finely crush large-grained stones, and the processing efficiency is remarkable. However, there are still deficiencies in the existing ball mill during use. After the iron ball media inside the ball mill continuously collide with the stones, the iron balls are worn, and iron filings will remain on the surface of the stones. The iron filings mixed in the stones will affect the quality of the crushed stones, which is not conducive to the later use of the fine-grained stones as mortar raw materials. Content of the Utility Model

[0004] The utility model provides a fine stone crushing device to solve the problem that after the iron ball media inside the existing ball mill continuously collide with the stones, the iron balls are worn and iron filings will remain on the surface of the stones.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fine stone crushing device includes a bracket. One end of the bracket is fixed with a support seat. A ball mill device is arranged on the top of the bracket. The ball mill device includes a crushing cylinder. One end of the crushing cylinder is provided with a feed pipe, and the other end is provided with a discharge pipe. An impurity removal mechanism is arranged on the top of the bracket. The impurity removal mechanism includes a guide plate. A sieve plate is arranged inside the guide plate. A flexible magnetic plate is arranged above the sieve plate. One end of the flexible magnetic plate is provided with a main roller, and the other end is provided with a secondary roller. Both ends of the flexible magnetic plate can be wound around the outside of the main roller and the secondary roller. A first support frame is arranged outside the main roller, and a second support frame is arranged outside the secondary roller. Driving motors are arranged at the same-side ends of the first support frame and the second support frame, and electromagnets are fixed at the other-side ends. The driving motors are used to drive the main roller and the secondary roller to rotate.

[0007] Preferably, the guide plate is of a U-shaped structure. The sieve plate is parallel to the guide plate. The guide plate and the sieve plate are inclined.

[0008] Preferably, a fixing plate is fixed to the bottom of the material guiding plate, and a vibration motor is fixedly connected to the bottom of the fixing plate through bolts.

[0009] Preferably, through holes are formed in both side walls at the top end of the material guiding plate, and both ends of the flexible magnetic plate can penetrate through the two through holes.

[0010] Preferably, the ball milling device further includes a driving assembly. The driving assembly includes a motor fixed to the top of the bracket. A first pulley is arranged at the end of the output shaft of the motor. A second pulley is arranged on the outer wall of the crushing cylinder. A belt is arranged between the first pulley and the second pulley. Hollow shafts are arranged between the feeding port of the crushing cylinder and the feeding pipe, and between the discharging port of the crushing cylinder and the discharging pipe. Axle seats are arranged on both sides of the top of the bracket close to the crushing cylinder. Both of the hollow shafts penetrate through the axle seats.

[0011] Preferably, cleaning components are arranged at the bottoms of the first support frame and the second support frame. The cleaning components include suspension rods fixed to the bottoms of the first support frame and the second support frame. A sliding plate is fixed to the bottom end of the suspension rod. A scraping plate is further fixed to one side wall of the suspension rod. The end of the scraping plate can be in contact with the flexible magnetic plate wound around the main winding roller and the auxiliary winding roller. The end of the scraping plate is a soft structure.

[0012] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0013] (1) Through the impurity removal mechanism provided, after the stones are crushed by the ball milling device and discharged from the discharge pipe, they then fall on the sieve plate of the impurity removal mechanism. Under the vibration action of the vibration motor, the fine-grained stones vibrate. The flexible magnetic plate above the sieve plate adsorbs the iron filings on the surface of the stones. The sieve plate is inclined. The stones move from one end of the sieve plate to the other end. During this process, the iron filing impurities in the stones are adsorbed by the flexible magnetic plate, thereby achieving the purpose of impurity removal, reducing the iron filing impurities in the stones, improving the quality of the crushing treatment of the stones, and being beneficial to the later use of the stones.

[0014] (2) By arranging the cleaning component on the support frame of the impurity removal mechanism, the cleaning component can scrape the iron powder on the surface of the flexible magnetic plate during the movement of the flexible magnetic plate and discharge it to one side of the support frame, automatically collecting the iron powder and quickly removing the iron powder impurities, which is beneficial to the recycling of the flexible magnetic plate.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a stone fine crushing device as shown in Figures 1 - 5 which includes a support 9. One end of the support 9 is fixed with a support seat 18. A ball milling device is arranged on the top of the support 9. The ball milling device includes a crushing cylinder 2. One end of the crushing cylinder 2 is provided with a feed pipe 1, and the other end is provided with a discharge pipe 7.

[0024] The top of the support 9 is provided with a impurity removal mechanism. The impurity removal mechanism includes a material guiding plate 10. Inside the material guiding plate 10, a sieve plate 11 is arranged. Above the sieve plate 11, a flexible magnetic plate 23 is arranged. One end of the flexible magnetic plate 23 is provided with a main roller 16, and the other end is provided with a secondary roller 17. Both ends of the flexible magnetic plate 23 can be wound around the outside of the main roller 16 and the secondary roller 17. Outside the main roller 16, a first support frame 8 is arranged. Outside the secondary roller 17, a second support frame 12 is arranged. At the same side ends of the first support frame 8 and the second support frame 12, driving motors 13 are arranged, and at the other side ends, electromagnets 20 are fixed. The driving motors 13 are used to drive the main roller 16 and the secondary roller 17 to rotate;

[0025] During the work of crushing stones, the stones need to be put into the inside of the feed pipe 1 from the port of the feed pipe 1. The stones enter the crushing cylinder 2 along the feed pipe 1, and then are crushed under the action of being impacted by the iron ball grinding medium inside the crushing cylinder 2.

[0026] As Figures 1 - 4 shown, specifically, the material guiding plate 10 is of a U-shaped structure. The sieve plate 11 is parallel to the material guiding plate 10, and the material guiding plate 10 and the sieve plate 11 are inclined;

[0027] During the movement of the stones, the stones roll on the tops of the inclined material guiding plate 10 and the sieve plate 11, which is beneficial to the movement of the stones from one end of the material guiding plate 10 and the sieve plate 11 to the other end, so that the stones after impurity removal can be discharged without clogging problems.

[0028] As Figures 1 - 4 shown, further, a fixing plate 22 is fixed to the bottom of the material guiding plate 10, and a vibration motor 19 is fixedly connected to the bottom of the fixing plate 22 through bolts;

[0029] After starting the vibration motor 19, the vibration generated by the vibration motor 19 is transmitted to the fixing plate 22 and the material guiding plate 10. The material guiding plate 10 drives the sieve plate 11 to vibrate. After the stones fall on the top of the sieve plate 11, the stones vibrate. During the vibration process, when the stones approach the flexible magnetic plate 23, the iron powder on the surface of the stones is adsorbed by the magnetism of the flexible magnetic plate 23, so as to achieve the purpose of impurity removal.

[0030] As Figures 1 - 4 shown, it should be noted that through holes 21 are opened on both side walls at the top end of the material guiding plate 10, and both ends of the flexible magnetic plate 23 can penetrate through the two through holes 21;

[0031] During the transverse movement of the flexible magnetic plate 23, it passes through the through holes 21 to move. The length of the flexible magnetic plate 23 is twice the distance between the central axis of the main roller 16 and the central axis of the secondary roller 17, so that the flexible magnetic plate 23 can be continuously wound around the outside of the main roller 16 or the secondary roller 17.

[0032] As Figure 1As shown, in this embodiment, the ball milling device further includes a driving assembly. The driving assembly includes a motor 5 fixed to the top of the bracket 9. A first pulley is provided at the end of the output shaft of the motor 5. A second pulley 3 is provided on the outer wall of the crushing cylinder 2. A belt 4 is provided between the first pulley and the second pulley 3. Hollow shafts are provided between the feed inlet of the crushing cylinder 2 and the feed pipe 1, and between the discharge outlet of the crushing cylinder 2 and the discharge pipe 7. Axle seats 6 are provided on both sides of the top of the bracket 9 close to the crushing cylinder 2. Both of the hollow shafts penetrate through the axle seats 6.

[0033] During the process of crushing stones, after the stones enter the crushing cylinder 2, the motor 5 is started. The output shaft of the motor 5 drives the first pulley to rotate. The first pulley drives the belt 4 to move. The belt 4 drives the second pulley 3 to rotate. The second pulley 3 drives the crushing cylinder 2 to rotate. The iron ball grinding medium inside the crushing cylinder 2 rolls inside the crushing cylinder 2 and collides with the stones, thereby crushing the stones.

[0034] As Figure 4 and Figure 5 In another embodiment shown, cleaning components are provided at the bottoms of the first support frame 8 and the second support frame 12. The cleaning components include suspension rods 151 fixed to the bottoms of the first support frame 8 and the second support frame 12. A sliding plate 15 is fixed to the bottom end of the suspension rod 151. A scraping plate 14 is further fixed to one side wall of the suspension rod 151. The end of the scraping plate 14 can be in contact with the flexible magnetic plate 23 wound around the outer sides of the main winding roller 16 and the auxiliary winding roller 17. The end of the scraping plate 14 is a soft structure.

[0035] In this embodiment, specifically, during the impurity removal process, it is necessary to clean the iron powder on the surface of the flexible magnetic plate 23, so as to ensure that the flexible magnetic plate 23 can be continuously used and prevent the iron powder from accumulating on the surface of the flexible magnetic plate 23 and causing the flexible magnetic plate 23 to lose its magnetic attraction effect. In the specific operation, the driving motor 13 is started. The output shaft of the driving motor 13 drives the main winding roller 16 to rotate. The main winding roller 16 winds the flexible magnetic plate 23. The flexible magnetic plate 23 is wound around the outer side of the main winding roller 16. During this process, the end of the scraping plate 14 contacts the surface of the flexible magnetic plate 23, thereby scraping off the iron powder. The iron powder falls on the top of the sliding plate 15 and slides down under its own gravity.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
