Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to an abrasive slurry control device. Background Technology

[0002] Wet grinding using ball mills can effectively improve grinding efficiency, reduce dust pollution, and is suitable for processing certain special materials. It is widely used in many industrial fields (such as mining, ceramics, and chemicals).

[0003] For example, Chinese patent CN218797325U describes a grinding ball screening machine, which includes a frame and a screening assembly located on the frame. The screening assembly includes a hopper and a screening module arranged below the bottom of the hopper and connected to the hopper. The screening module includes a sieve plate, a grinding ball receiving plate arranged at the bottom of the sieve plate, an upper discharge receiving plate connected to the discharge end of the sieve plate, an upper discharge hopper connected to the outer discharge port of the upper discharge receiving plate, a pad plate at the bottom of the grinding ball receiving plate, and a vibration mechanism at the bottom of the pad plate. However, this screening machine still has the following problems:

[0004] In a ball mill, grinding balls gradually wear down and shrink in size due to long-term impact and friction. Since the grinding of small balls is mainly based on friction, the impact crushing ability decreases. After wear, small balls mix with unworn balls, resulting in a disordered distribution of grinding media of different sizes. Large particles may not be fully crushed, while some fine particles are over-ground to form ultrafine powder. This makes it difficult for the screening machine to automatically screen grinding balls of different diameters.

[0005] Based on this, the present invention designs an abrasive slurry control device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an abrasive slurry control device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An abrasive slurry control device includes an upper frame and a lower frame;

[0009] The upper frame is fixedly installed on the upper end of the lower frame. The upper frame is connected to four legs by four elastic columns. A vibration motor is fixedly installed on the lower end of the lower frame.

[0010] Side plates are fixedly installed on the upper frame; a discharge hopper for receiving the separated abrasive slurry is fixedly installed at the rear end of the lower frame, and multiple ball receiving frames for receiving grinding balls of different diameters are set at the front end of the lower frame.

[0011] The upper frame is also equipped with an adjustable screen body, which includes screen rods and an angle synchronization adjustment component. There are multiple screen rods, and the screen rods are evenly distributed at equal intervals along the width of the upper frame. The angle synchronization adjustment component is located at the discharge end of the upper frame. One end of the screen rod is hinged to the feed end of the upper frame, and the other end of the screen rod is connected to the angle synchronization adjustment component. The angle synchronization adjustment component is used to control the screen rods to open synchronously to the left and right sides.

[0012] Furthermore, the angle synchronization adjustment component includes a sliding pin, an adjustment plate, and a distance adjustment component. The lower end of the screen rod is fixedly installed with a sliding pin. The adjustment plate is slidably connected to the upper frame. The adjustment plate has multiple sliding grooves that correspond one-to-one with the sliding pins and are slidably connected to them for limiting. The sliding groove on the left side is inclined to the left, and the sliding groove on the right side is inclined to the right. The distance adjustment components are symmetrically arranged on the left and right sides of the upper frame. The distance adjustment components are used to control the forward and backward movement of the adjustment plate.

[0013] Furthermore, the feed end of the upper rack is also equipped with a uniform rinsing mechanism to fully separate the abrasive slurry poured into the feed end of the upper rack from the grinding balls.

[0014] Furthermore, the uniform rinsing mechanism includes a rinsing component and a synchronous reciprocating drive component. The rinsing component is located on the upper side of the upper feed end, and multiple sets of rinsing components are arranged along the length of the upper frame. The synchronous reciprocating drive component is symmetrically arranged at both ends of the rinsing component to control the rinsing component to move back and forth to uniformly clean the grinding balls.

[0015] Furthermore, the rinsing assembly includes nozzles, crossbars, and brackets. The brackets are symmetrically fixedly installed on the left and right sides of the side plate. The two ends of the crossbar are respectively limited and slidably connected to the brackets on the left and right sides. Multiple nozzles are evenly fixedly installed on the crossbar at equal intervals along the length of the crossbar.

[0016] Furthermore, the synchronous reciprocating drive assembly includes a gear, a rack, a support plate, a rotating shaft, and a drive motor. The rack is fixedly installed at the end of the crossbar, and a gear is provided between the racks on adjacent crossbars, and the gear meshes with the adjacent racks. The support plate is fixedly connected to the upper frame, and the gear is rotatably connected to the support plate through the rotating shaft. The lower end of the support plate is fixedly installed with a drive motor, and the output end of the drive motor is fixedly connected to the rotating shaft.

[0017] Furthermore, multiple partitions are fixedly installed on the upper shelf, and the partitions are inclined and alternately distributed left and right along the length of the upper shelf.

[0018] Furthermore, multiple sets of locking components for limiting the connection of the ball frame are provided between the upper and lower shelves.

[0019] Compared with the prior art, the advantages of this utility model are as follows: 1. The vibrating motor drives the upper and lower frames to vibrate. The abrasive slurry is poured from the rear end of the upper frame onto the adjustable screen body. The uniform rinsing mechanism continuously flushes water onto the slurry, causing the grinding balls and slurry to separate. The slurry flows through the adjustable screen body into the discharge hopper and is collected from the discharge port of the discharge hopper. The grinding balls roll on the adjustable screen body to the discharge end of the upper frame. During the rolling process, grinding balls that have shrunk to a set size due to wear will pass through the adjustable screen body and fall into the ball receiving frame for collection. Grinding balls of different sizes will fall into different ball receiving frames, realizing the automatic sorting of grinding balls.

[0020] 2. In the initial state, all screen bars are set in parallel, and the distance between adjacent screen bars is always the same. The slurry will fall through the screen bars, while the grinding balls will roll along the screen bars. By rotating the screw, the adjusting plate is moved along the length of the upper frame, so that the end of the screen bar located at the discharge end of the upper frame opens synchronously with the cooperation of the sliding pin and the sliding groove. This makes the distance between adjacent screen bars gradually increase from the feed end of the upper frame to the discharge end of the upper frame. When the distance between the screen bars is greater than its diameter, the small grinding balls will pass through the screen bars and fall into the ball receiving frame, thereby realizing the automatic sorting and collection of grinding balls.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 An abrasive slurry control device includes an upper frame 10 and a lower frame 11;

[0032] The upper frame 10 is fixedly installed on the upper end of the lower frame 11. The upper frame 10 is connected to the four legs respectively through four elastic columns. The lower end of the lower frame 11 is fixedly installed with a vibration motor 4.

[0033] A side plate 12 is fixedly installed on the upper frame 10; a discharge hopper 14 for receiving the separated abrasive slurry is fixedly installed at the rear end of the lower frame 11, and multiple ball receiving frames 15 for receiving grinding balls of different diameters are provided at the front end of the lower frame 11.

[0034] An adjustable screen body 2 is also provided on the upper frame 10. The adjustable screen body 2 includes screen rods 21 and an angle synchronization adjustment component. Multiple screen rods 21 are provided and are evenly distributed at equal intervals along the width direction of the upper frame 10. The angle synchronization adjustment component is located at the discharge end of the upper frame 10. One end of the screen rod 21 is hinged to the feed end of the upper frame 10, and the other end of the screen rod 21 is connected to the angle synchronization adjustment component. The angle synchronization adjustment component is used to control the screen rods 21 to open synchronously to the left and right sides.

[0035] The feed end of the upper frame 10 is also equipped with a uniform rinsing mechanism 3, which is used to fully separate the abrasive slurry poured into the feed end of the upper frame 10 from the grinding balls;

[0036] In this invention, the vibration motor 4 drives the upper frame 10 and the lower frame 11 to vibrate. The abrasive slurry is poured from the rear end of the upper frame 10 onto the adjustable screen body 2. The uniform rinsing mechanism 3 continuously flushes water onto the slurry, causing the grinding balls and slurry to separate. The slurry flows through the adjustable screen body 2 into the discharge hopper 14 and is collected from the discharge port of the discharge hopper 14. Meanwhile, the grinding balls roll on the adjustable screen body 2 to the discharge end of the upper frame 10. During the rolling process, grinding balls that have shrunk to a set size due to wear will fall through the adjustable screen body 2 into the ball receiving frame 15 and be collected. Grinding balls of different sizes will fall into different ball receiving frames 15, thus realizing the automatic sorting of grinding balls.

[0037] Please see Figures 2-4 Multiple sets of locking components for limiting the ball receiving frame 15 are also provided between the upper frame 10 and the lower frame 11. The locking components are distributed along the length of the upper frame 10 and the lower frame 11. The locking components include a fixed baffle 16, a movable baffle 17 and a support block 18. The fixed baffle 16 is fixedly installed on one side of the upper frame 10 and the lower frame 11, and the support block 18 is fixedly installed on the other side of the upper frame 10. The movable baffle 17 is L-shaped, and the lower end of the movable baffle 17 is inserted into the support block 18. The fixed baffle 16 and the movable baffle 17 cooperate to limit the ball receiving frame 15 between the upper frame 10 and the lower frame 11 from the side. The locking and unlocking control effect of the ball receiving frame 15 can be achieved by controlling the lifting of the movable baffle 17.

[0038] Please see Figure 4 and Figure 6 The angle synchronization adjustment component includes a sliding pin 22, an adjusting plate 23, and a distance adjustment component. The lower end of the screen rod 21 is fixedly installed with the sliding pin 22. The adjusting plate 23 is slidably connected to the upper frame 10. The adjusting plate 23 has multiple sliding grooves 24 that correspond one-to-one with the sliding pin 22 and are slidably connected to it. The sliding groove 24 on the left side is inclined to the left, and the sliding groove 24 on the right side is inclined to the right. The distance adjustment components are symmetrically arranged on the left and right sides of the upper frame 10. The distance adjustment components are used to control the forward and backward movement of the adjusting plate 23.

[0039] The adjustable distance assembly includes a screw 25, a fixed block 26 and a movable block 27. The fixed block 26 is fixedly connected to the upper frame 10, the movable block 27 is fixedly connected to the adjusting plate 23, the screw 25 is rotatably connected to the fixed block 26 through a bearing, and the screw 25 is threadedly connected to the movable block 27 through a threaded sleeve.

[0040] In this invention, in the initial state, all the screen rods 21 are arranged in parallel, and the distance between adjacent screen rods 21 is always the same. The slurry will fall through the screen rods 21, and the grinding balls will roll along the screen rods 21. By rotating the screw 25, the adjusting plate 23 is controlled to move along the length of the upper frame 10, so that the end of the screen rod 21 at the discharge end of the upper frame 10 opens synchronously with the cooperation of the sliding pin 22 and the sliding groove 24. This makes the distance between adjacent screen rods 21 gradually increase from the feed end of the upper frame 10 to the discharge end of the upper frame 10. When the distance between the screen rods 21 is greater than its diameter, the small grinding balls will pass through the screen rods 21 and fall into the ball receiving frame 15, thereby realizing the automatic sorting and collection of grinding balls.

[0041] The uniform rinsing mechanism 3 includes a rinsing component and a synchronous reciprocating drive component. The rinsing component is located on the upper side of the feed end of the upper frame 10, and multiple sets of rinsing components are arranged along the length of the upper frame 10. The synchronous reciprocating drive component is symmetrically arranged at both ends of the rinsing component to control the rinsing component to move back and forth to uniformly clean the grinding balls.

[0042] Please see Figure 2 , Figure 3 and Figure 5 The flushing assembly includes a nozzle 31, a crossbar 32, and a bracket 33. The bracket 33 is symmetrically fixedly installed on the left and right sides of the side plate 12. The two ends of the crossbar 32 are respectively limited and slidably connected to the brackets 33 on the left and right sides. Multiple nozzles 31 are evenly fixedly installed on the crossbar 32 at equal intervals along the length of the crossbar 32. The nozzles 31 are connected to external water supply equipment such as a water pump.

[0043] The synchronous reciprocating drive assembly includes a gear 34, a rack 35, a support plate 36, a rotating shaft 37, and a drive motor 38. The rack 35 is fixedly installed at the end of the crossbar 32. A gear 34 is provided between the racks 35 on adjacent crossbars 32, and the gear 34 is meshed with the adjacent racks 35. The support plate 36 is fixedly connected to the upper frame 10. The gear 34 is rotatably connected to the support plate 36 through the rotating shaft 37. The drive motor 38 is fixedly installed at the lower end of the support plate 36, and the output end of the drive motor 38 is fixedly connected to the rotating shaft 37.

[0044] In this invention, the drive motor 38 drives the gear 34 to continuously rotate forward and backward through the rotating shaft 37. Under the cooperation of the gear 34 and the rack 35, all the crossbars 32 reciprocate linearly, thereby thoroughly washing the slurry and grinding balls on the screen bar 21 through the nozzle 31.

[0045] Multiple partitions 13 are fixedly installed on the upper frame 10. The partitions 13 are inclined and alternately distributed left and right along the length of the upper frame 10, which effectively extends the movement path of the slurry and grinding balls on the screen rod 21 and avoids the local wear speed of the screen rod 21 being accelerated due to the accumulation of slurry and grinding balls in specific positions on the screen rod 21.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
