Description

Technical Field

[0001] This utility model relates to the technical field of ball milling devices, and in particular to a ball milling device for crushing muddy ore. Background Technology

[0002] A ball mill is a device used for grinding and crushing materials. When the cylinder rotates, the grinding media are carried to a certain height and fall down under the action of centrifugal force and friction. The material is crushed by impact, grinding and rolling. In the large-scale processing of muddy minerals, ball mills are often used for large-tonnage crushing.

[0003] Chinese Patent Publication No. CN216499742U discloses an energy-saving wet ball mill device for mineral powder, including a cylindrical body. Support legs are fixedly connected to the bottom of the cylindrical body, and a motor is mounted on the cylindrical body. The output shaft of the motor passes through the cylindrical body and is rotatably connected to it, facilitating feeding and guiding the material flow while preventing material from flowing out of the feed inlet. The existing technical solution has the following shortcomings: During use, the device has a single-chamber structure. When the grinding balls and materials collide and grind, the grinding efficiency varies due to the different sizes of the ores. After some parts are finely ground, the lack of an effective sieve in the device can easily lead to over-grinding of some mineral powder. Therefore, there is room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a ball milling device for crushing muddy ore, so as to solve the problem mentioned in the background art that the existing ball milling devices for crushing muddy ore are not easy to screen the ore in time, and are prone to over-grinding some ore.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ball mill device for crushing muddy ore, comprising a base plate, bearing seats on both sides of the top of the base plate, and a rotating cylinder passing through between the two bearing seats, a rotating mechanism being provided at one end of the outer side of the rotating cylinder, an inclined partition plate being fixedly connected inside the rotating cylinder, the inclined partition plate being inclined, a plurality of grinding balls being filled inside the rotating cylinder on one side of the inclined partition plate, an equally divided groove being provided at the bottom end of the inclined partition plate away from the grinding balls, and a plurality of filter holes passing through the interior of the equally divided groove, an opening and closing mechanism being provided outside the filter holes to control the timing of opening and closing of the filter holes;

[0006] The opening and closing mechanism includes two parallel fixed shafts fixed at the top of the inside of the filter hole, and each fixed shaft is fitted with an opening and closing plate. The outer side of each opening and closing plate is connected to a spring, and one end of each spring is connected to the inside of the inclined partition. The fixed shafts are located above the filter hole. The top of the inside of the inclined partition is provided with an opening and closing component, and both sides of the bottom end of the opening and closing component are connected to the inner side of the opening and closing plate on the same side.

[0007] Preferably, the rotating mechanism includes a gear ring fixedly sleeved on the outside of the rotating cylinder, a support frame is provided on one side of the top of the base plate, and a motor is fixedly installed on one side of the support frame. The output end of the motor is connected to a gear, and the outer side of the gear and the outer side of the gear ring mesh with each other.

[0008] Preferably, the opening and closing assembly includes a sliding cavity formed at the top of the inside of the inclined partition, and a sliding plate is slidably installed inside the sliding cavity. A pull rope is connected to the side of the sliding plate near the opening and closing plate, and one end of the pull rope extends into the inside of the equally divided groove and is connected to a connecting rope. The two ends of the connecting rope are respectively connected to the inner side of one side of the opening and closing plate.

[0009] Preferably, when the slide plate slides away from the hinged plate, the pull rope pulls the two hinged plates on the left and right to rotate inward and close the filter hole. At this time, the inclined partition is inclined downward from left to right.

[0010] Preferably, the skateboard is made of metal, a support base is fixed to the top of the base plate, and a semi-circular magnetic plate is fixed to the top of the support base. The top surface of the semi-circular magnetic plate abuts against the outer wall of the rotating cylinder, and the semi-circular magnetic plate exerts an attractive force on the skateboard.

[0011] Preferably, both sides of the sliding cavity are provided with a clearing mechanism, and one end of the clearing mechanism extends into the interior of the opening and closing plate on the same side. The filter hole is cleared by blowing air during the opening and closing movement of the opening and closing plate using the clearing mechanism.

[0012] Preferably, the unblocking mechanism includes an airbag installed at the bottom of the sliding cavity, and the bottom of the airbag is connected to a hose. An exhaust pipe runs through one side of the opening and closing plate, and multiple exhaust ports are evenly arranged on the side of the exhaust pipe near the filter hole. The outer ends of the exhaust ports penetrate the inner wall of the opening and closing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The inner cavity of the rotating drum is divided into two parts by the inclined partition and combined with the filter hole to facilitate the filtering of the finely crushed ore after ball milling, so that the fine ore enters the collection cavity from the ball milling cavity, thereby reducing the over-grinding of the ore. At the same time, the filter hole is open when it is in the low position by the action of the opening and closing mechanism. Since the inclined partition is inclined towards the collection cavity at this time, the finely crushed ore can fall into the filter hole for filtering during the throwing process. The inclined setting and the closable nature of the filter hole reduce the backflow of finely crushed ore.

[0016] (2) By utilizing the up-and-down sliding property of the pull rope, the airbag is subjected to pressure and reset, so that when the opening and closing plate opens the filter hole, the gas inside the airbag can be discharged from the outlet. Due to the rotation of the opening and closing plate, the discharged gas is sprayed onto the filter hole in sequence to clean and unclog the filter hole and reduce blockage.

[0024] 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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1-5 An embodiment of this utility model is provided: a ball mill device for crushing mud minerals, including a base plate 1, bearing seats 2 are provided on both sides of the top of the base plate 1, and a rotating cylinder 3 is provided through the two bearing seats 2, and a rotating mechanism 4 is provided at one end of the outer side of the rotating cylinder 3.

[0026] The rotating mechanism 4 includes a gear ring 44 fixedly sleeved on the outside of the rotating drum 3. A support frame 41 is provided on one side of the top of the base plate 1, and a motor 42 is fixedly installed on one side of the support frame 41. The output end of the motor 42 is connected to a gear 43, and the outer side of the gear 43 and the outer side of the gear ring 44 mesh with each other.

[0027] Specifically, such as Figure 1 As shown, during use, the meshing of gear 43 and gear ring 44 is used to realize the rotation of the rotating drum 3, thereby realizing the throwing of grinding balls 7 inside the rotating drum 3 under the action of rotation and centrifugal force, thus crushing the muddy ore.

[0028] An inclined partition 8 is fixedly connected inside the rotating cylinder 3, and the inclined partition 8 is inclined. The interior of the rotating cylinder 3 on one side of the inclined partition 8 is filled with multiple grinding balls 7. An equally divided groove 9 is opened at the bottom end of the inclined partition 8 away from the grinding balls 7, and multiple filter holes 10 are provided through the interior of the equally divided groove 9. An opening and closing mechanism 11 is provided on the outside of the filter holes 10 to control the opening and closing timing of the filter holes 10.

[0029] The opening and closing mechanism 11 includes two parallel fixed shafts 111 fixed inside the top of the filter hole 10, and opening and closing plates 112 are sleeved on the outside of the fixed shafts 111. Springs 113 are connected to the outside of the opening and closing plates 112, and one end of each spring 113 is connected to the inside of the inclined partition 8. The fixed shafts 111 are located above the filter hole 10. An opening and closing component 114 is provided at the top of the inside of the inclined partition 8, and both sides of the bottom end of the opening and closing component 114 are connected to the inside of the opening and closing plate 112 on the same side.

[0030] The opening and closing assembly 114 includes a sliding cavity 1141 formed at the top of the inside of the inclined partition 8, and a sliding plate 1142 is slidably installed inside the sliding cavity 1141. A pull rope 1143 is connected to the side of the sliding plate 1142 near the opening and closing plate 112, and one end of the pull rope 1143 extends into the inside of the equally divided groove 9 and is connected to a connecting rope 1144. The two ends of the connecting rope 1144 are respectively connected to the inner side of one side of the opening and closing plate 112.

[0031] When the slide plate 1142 slides away from the hinge plate 112, the pull rope 1143 pulls the two hinge plates 112 on the left and right to rotate inward and close the filter hole 10. At this time, the inclined partition 8 is tilted downward from left to right.

[0032] The skateboard 1142 is made of metal. A support base 5 is fixed to the top of the base plate 1, and a semi-circular magnetic plate 6 is fixed to the top of the support base 5. The top surface of the semi-circular magnetic plate 6 abuts against the outer wall of the rotating cylinder 3, and the semi-circular magnetic plate 6 exerts an attractive force on the skateboard 1142.

[0033] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, during use, the inclined partition 8 rotates with the rotating drum 3, causing the sliding plate 1142 to slide relative to each other under the attraction of gravity and the semi-circular magnetic plate 6, thereby realizing the opening and closing of the opening and closing plate 112 to control the opening and closing of the filter hole 10, so as to prevent the fine mud ore after crushing from flowing back from the collection chamber to the ball mill chamber and avoid excessive finening by the ball mill.

[0034] Both sides of the sliding cavity 1141 are provided with unblocking mechanisms 12, and one end of the unblocking mechanism 12 extends into the interior of the opening and closing plate 112 on the same side. The filter hole 10 is unblocked by blowing air during the opening and closing movement of the unblocking mechanism 12 and the opening and closing plate 112.

[0035] The unblocking mechanism 12 includes an airbag 121 installed at the bottom of the sliding cavity 1141, and the bottom end of the airbag 121 is connected to a hose 124. An exhaust pipe 123 is passed through one side of the opening and closing plate 112, and multiple outlets 125 are evenly arranged on the side of the exhaust pipe 123 near the filter hole 10. The outer end of the outlet 125 passes through the inner wall of the opening and closing plate 112. The bottom end of the hose 124 extends into the interior of the equally divided groove 9 and is connected to one end of the exhaust pipe 123. A one-way air inlet pipe 122 is connected to the outside of the airbag 121, and the air inlet end of the one-way air inlet pipe 122 extends to the side of the inclined partition 8 near the grinding ball 7.

[0036] The airbag 121 is located below the slide plate 1142. When the slide plate 1142 approaches the opening and closing plate 112, the airbag 121 is compressed and discharged. Two protective covers 13 are fixed on the outside of the inclined partition 8, and the protective covers 13 are located outside the air inlet end of the one-way air inlet pipe 122.

[0037] Specifically, such as Figure 3 and Figure 5 As shown, during use, the sliding properties of the slide plate 1142 are used to compress the airbag 121, thereby achieving one-way discharge of air inside the airbag 121 and thus achieving the exhaust and unblocking effect of the filter hole 10.

[0038] Working principle: When using this utility model, the muddy ore is first introduced into the ball mill chamber where the grinding balls 7 are located through the feed port at one end of the rotating drum 3. The motor 42 is started, which causes the gear 43 to drive the gear ring 44 to mesh and rotate, thereby rotating the rotating drum 3. The grinding balls 7 move to the highest point under centrifugal force and then fall. Then, the gravity of the falling balls is used to crush the muddy ore, thereby achieving the crushing effect.

[0039] Secondly, during the crushing process, when the muddy ore in the ball mill chamber is refined, some of the ore that meets the particle standard will pass through the filter hole 10 through the inclined surface of the inclined partition plate 8 when the filter hole 10 is at the lowest point in the rotating drum 3, so that the refined muddy ore enters the collection chamber. At this time, due to the gravity and the attraction of the lower semi-circular magnetic plate 6, the sliding plate 1142 is in the closest position to the opening and closing plate 112. At the same time, the opening and closing plate 112 is in an open state under the pulling force of the spring 113 to ensure that the filter hole 10 is in an open state.

[0040] When the drum 3 rotates, the inclined partition 8 rotates synchronously, and the filter hole 10 rotates from the bottom to the top. At this time, under the gravity of the slide plate 1142 and the attraction of the semi-circular magnetic plate 6, the slide plate 1142 moves away from the closing plate 112, thereby pulling the pull rope 1143, so that the connecting rope 1144 pulls the two opening and closing plates 112 inward, so that the two opening and closing plates 112 move closer to each other, and then the filter hole 10 closes. Since the bottom end of the inclined partition 8 is tilted towards the position of the collection chamber at this time, the material inside the collection chamber is prevented from flowing back into the ball mill chamber.

[0041] Finally, during the sliding process of the slide plate 1142 relative to the opening and closing plate 112, the slide plate 1142 exerts a reciprocating squeezing effect on the airbag 121, thereby causing the gas inside the airbag 121 to be discharged to the exhaust pipe 123 when it is squeezed. That is, when the slide plate 1142 approaches the opening and closing plate 112, the opening and closing plate 112 unfolds, and the airbag 121 is compressed, causing the gas to be discharged from the outlet 125. Since the opening and closing plate 112 is in the unfolded state, the ejected gas sequentially clears the filter hole 10.
