Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ball milling equipment, in particular to a ball milling system applied to phosphorus pentasulfide. BACKGROUND

[0002] Phosphorus pentasulfide is an inorganic compound with the chemical formula P2S5, which is a yellow and yellow-green crystalline substance, stable when dry, but easily hydrolyzed into phosphoric acid and hydrogen sulfide when coming into contact with water. With the development of the automobile, petroleum, pharmaceutical and other industries, the demand for high-quality phosphorus pentasulfide powder is increasing year by year. The existing synthesis method of phosphorus pentasulfide is mainly liquid phase method (preparation method of phosphorus pentasulfide), in which liquid elemental sulfur (sulfur) and phosphorus (yellow phosphorus) are introduced into a reaction kettle according to the stoichiometric ratio to react, and the obtained reaction product is purified by distillation, and then the purified liquid phosphorus pentasulfide is cooled and solidified.

[0003] After the liquid phosphorus pentasulfide is cooled and solidified, phosphorus pentasulfide crystals are formed, and the crystals are irregular in shape. In order to reasonably utilize phosphorus pentasulfide, the phosphorus pentasulfide crystals need to be put into a ball mill for ball milling, so that the crystals are ball milled into powder, so as to reasonably utilize phosphorus pentasulfide.

[0004] However, the existing method is to directly put the phosphorus pentasulfide crystals into the ball mill for ball milling, but due to the uncertainty of the volume of the phosphorus pentasulfide crystals, the volume seriously affects the ball milling speed, so the existing method is to ball mill a large amount of crystals with different volumes in a ball milling cavity, which has a slow ball milling speed and may cause uneven distribution of the ground material particles, affecting the product quality.

[0008] One of the two ball mill liners is fixedly connected to one side of the filter partition set, and the other ball mill liner is movably connected to the other side of the filter partition set through the transmission assembly, so that when the shell rotates relative to the support frame, the transmission assembly drives one end of one ball mill liner to rotate relative to the other ball mill liner and reciprocate, so that one ball mill liner performs cyclic motion in the horizontal direction and the inclined direction, so that the material in one ball mill liner that meets the target size after ball milling enters the other ball mill liner for ball milling after being filtered by the filter partition set.

[0011] Further, a plurality of clamping pieces are arranged at intervals along the circumferential inner wall of the first movable cavity, and a plurality of adapter pieces are arranged at intervals along the circumferential outer wall of the first ball mill liner.

[0012] Each of the clamping pieces is provided with a clamping gap for accommodating at least one of the adapter pieces, so that the first ball mill liner is fixedly connected to the first movable cavity by clamping each of the adapter pieces with the opposite clamping gap.

[0018] Further, the transmission assembly further comprises a second motor, a spur gear rotatably connected to the second ball mill inner container, a cam rotatably connected to the shell, and a plurality of second teeth arranged along the outer periphery of the cam at intervals.

[0019] The second motor is connected with the cam, so that the cam is driven to rotate by the second motor, so that the second ball mill inner container rotates relative to the shell and reciprocatingly swings along the length direction of the cam.

[0020] Further, the filter partition group comprises at least two filter discs rotatably connected to the middle part of the shell, and the aperture size of each filter hole on each filter disc is the same.

[0021] Further, the filter partition group comprises a first filter disc and a second filter disc, the first filter disc and the second filter disc are rotatably connected to each other, and by rotating one of the first filter disc and the second filter disc, the gap size between the filter holes on the first filter disc and the filter holes on the second filter disc is adjusted.

When the initial phosphorus pentasulfide crystals are ball milled, another ball mill inner shell is movably connected to the other side of the filter baffle group through the transmission assembly, so that when the shell rotates relative to the support frame, the transmission assembly drives one end of the ball mill inner shell to rotate and reciprocate relative to the other ball mill inner shell. Therefore, the initial phosphorus pentasulfide crystals can be first put into the ball mill inner shell movably connected with the transmission assembly, and the ball mill inner shell can be used for coarse ball milling of the initial phosphorus pentasulfide crystals, that is, the crystals with different particle sizes are coarsely milled so as to meet the target size. In the ball milling process, the ball mill inner shell can be moved during horizontal rotation, that is, when the ball mill inner shell is at an inclined angle, the phosphorus pentasulfide crystals in the ball mill inner shell can be filtered towards the filter baffle group, so that the phosphorus pentasulfide crystals meeting the target size are finely milled. In the ball milling of phosphorus pentasulfide crystals with different volumes, the initial phosphorus pentasulfide crystals are first coarsely milled and then finely milled.

[0037] Reference will now be made to Figures 1-8As shown, the application provides a ball milling system applied to phosphorus pentasulfide, which comprises a support frame 200 provided with a driving device 100, and a ball mill 300 arranged on the support frame 200, the ball mill 300 being in driving connection with the driving device 100, so as to drive the ball mill 300 to rotate relative to the support frame 200 through the driving device 100.

[0038] Specifically, in the embodiment, the ball mill 300 comprises a shell 310, a filter partition set 320, a transmission assembly 330, and at least two ball mill inner containers arranged in the shell 310, the filter partition set 320 being arranged in the shell 310, the two ball mill inner containers being arranged on opposite sides of the filter partition set 320 and being in communication with each other, and the filter partition set 320 being used for filtering the material in the ball mill inner containers.

[0039] In order to solve the technical problem that the volume of phosphorus pentasulfide crystals is uncertain, and the volume seriously affects the ball milling speed, and thus the existing ball milling system is slow in ball milling speed, and the distribution of the ground material is uneven, and the product quality is affected, in the embodiment, one of the two ball mill inner containers is fixedly connected to one side of the filter partition set 320, and the other ball mill inner container is movably connected to the other side of the filter partition set 320 through the transmission assembly 330, so that when the shell 310 rotates relative to the support frame 200, the transmission assembly 330 drives one end of the one ball mill inner container to rotate and reciprocate relative to the other ball mill inner container, so that the one ball mill inner container rotates and reciprocates in the horizontal direction and the inclined direction, and the material in the one ball mill inner container that meets the target size after ball milling is filtered through the filter partition set 320 and then enters the other ball mill inner container for ball milling.

[0040] That is, the ball mill liner is fixedly connected to one side of the filter baffle group 320, so that when the driving device 100 drives the ball mill 300 to rotate relative to the support frame 200, the shell 310 in the ball mill 300 drives the ball mill liner to rotate horizontally, that is, the ball mill liner can be used to finely mill the phosphorus pentasulfide crystals. In this embodiment, another ball mill liner is movably connected to the other side of the filter baffle group 320 through the transmission assembly 330, so that when the shell 310 rotates relative to the support frame 200, the transmission assembly 330 drives one end of the ball mill liner to rotate and reciprocate relative to the other ball mill liner. Therefore, the initial phosphorus pentasulfide crystals can be first put into the ball mill liner movably connected with the transmission assembly 330, and the ball mill liner can be used to coarsely mill the initial phosphorus pentasulfide crystals, that is, the crystals with different particle sizes are coarsely milled so that they can meet the target size. During the ball milling process, the ball mill liner can move back and forth during horizontal rotation, that is, when the ball mill liner is at an inclined angle, the phosphorus pentasulfide crystals in the ball mill liner can be filtered towards the filter baffle group 320, so that the phosphorus pentasulfide crystals meeting the target size are finely milled. In this way, when different volumes of phosphorus pentasulfide crystals are ball milled, the initial phosphorus pentasulfide crystals can be coarsely milled first and then finely milled. Compared with the prior art which uses one ball mill cavity for coarse and fine mixed ball milling, the ball milling system provided by the present application can greatly improve the ball milling speed and reduce the probability of uneven distribution of ground material particles, thereby ensuring the quality of the final product.

[0041] Specifically, in order to facilitate the rotation of the shell 310, the driving device 100 includes a first driving member 110, a transmission belt 120, and a plurality of first clamping teeth 130 arranged circumferentially along the outer wall of the shell 310. One part of the transmission belt 120 is transmissionally connected to the first clamping teeth 130 along the circumferential arrangement direction of the first clamping teeth 130, and the other part of the transmission belt 120 is connected to the output end of the first driving member 110. The first driving member 110 is used to drive the transmission belt 120 to move, so that the shell 310 rotates relative to the support frame 200.

[0042] Further, in order to facilitate understanding of the present case, the ball mill 300 can include two ball mill liners in this embodiment, specifically, the first ball mill liner 340 and the second ball mill liner 350. The shell 310 is divided into a first movable cavity 311 and a second movable cavity 312 by the filter baffle group 320, wherein the first ball mill liner 340 and the second ball mill liner 350 are arranged in the first movable cavity 311 and the second movable cavity 312, respectively.

[0043] It should be noted that in the prior art, the ball mill 300 includes a barrel, and grinding bodies are arranged in the barrel, the grinding bodies are generally steel balls, and are arranged in the barrel according to different diameters and a certain proportion. When the barrel of the ball mill 300 rotates, the grinding bodies are driven to move by the lining plate attached to the barrel due to inertia, centrifugal force and friction. When the grinding bodies are brought to a certain height, they are thrown down due to their own gravity, and the falling grinding bodies produce heavy blows and grinding effects on the materials in the barrel.

[0044] Therefore, the lining plate and the grinding bodies in the prior art can be arranged in the first ball mill inner container 340 and the second ball mill inner container 350 in the embodiment, so that the first ball mill inner container 340 and the second ball mill inner container 350 can perform ball milling on the phosphorus pentasulfide crystals.

[0045] Specifically, in order to facilitate driving the first ball mill inner container 340 to perform ball milling, a plurality of clamping pieces 360 are arranged at intervals along the circumferential inner wall of the first movable cavity 311, and a plurality of adapter pieces 370 are arranged at intervals along the circumferential outer wall of the first ball mill inner container 340. Each clamping piece 360 is provided with a clamping gap for accommodating at least one adapter piece 370. Each adapter piece 370 is clamped with the opposite clamping gap, so that the first ball mill inner container 340 is fixedly connected with the first movable cavity 311. Through the mutual cooperation between the plurality of clamping pieces 360 and the adapter pieces 370, the first ball mill inner container 340 can rotate along with the rotation of the shell 310.

[0046] In order to facilitate driving the second ball mill inner container 350 to perform ball milling, the transmission assembly 330 includes a plurality of interconnected linkage pipes 331. At least one end of at least one of the plurality of linkage pipes 331 is movably connected with the filter partition group 320, and at least one end of at least one of the plurality of linkage pipes 331 is movably connected with the second ball mill inner container 350. That is, the first end of the second ball mill inner container 350 is movably connected with the filter partition group 320 through the plurality of interconnected linkage pipes 331.

[0047] The transmission assembly 330 further includes a second motor 332, a spur gear 335 rotatably connected to the second ball mill inner container 350, a cam 333 rotatably connected to the shell 310, and a plurality of second clamping teeth 334 arranged at intervals along the outer periphery of the cam 333. The second clamping teeth 334 are in transmission connection with the spur gear 335. The second motor 332 is connected with the cam 333, so as to drive the cam 333 to rotate through the second motor 332, so that the second ball mill inner container 350 rotates relative to the shell 310 and reciprocatingly swings along the length direction of the cam 333. That is, the second end of the second ball mill inner container 350 is movably connected in the second movable cavity 312 through the spur gear 335, the cam 333 and the second motor 332.

[0048] Specifically, the cam 333 is driven to rotate by the second motor 332, and the plurality of second clamping teeth 334 on the cam 333 are in transmission connection with the spur gear 335, so that when the cam 333 rotates, the second ball mill inner container 350 can rotate by the mutual meshing between the gears, and the irregular shape of the cam 333 is used, please refer to Figure 4 and Figure 7 When the cam 333 rotates, the long side of the cam 333, which is the side of the cam 333, moves along the long side of the cam 333, thereby driving the rotating second ball mill inner container 350 to move upward, so that the second ball mill inner container 350 is in an inclined state, and when the cam 333 rotates to a certain extent, the spur gear 335 moves downward, so that the second ball mill inner container 350 switches from the inclined state to the horizontal state, so that the second ball mill inner container 350 can realize reciprocating swing in the normal ball mill, so that the phosphorus pentasulfide crystals meeting the target size after rough grinding can be filtered.

[0049] It should be noted that in some preferred embodiments, in order to ensure the stability of the rotation and reciprocating movement of the second ball mill inner container 350, the inner wall of the second movable cavity 312 can be limited, please refer to Figure 8 Specifically, a longitudinal sub-cavity is arranged at the front end of the second movable cavity 312, and the longitudinal sub-cavity is only a space for the reciprocating movement of the second ball mill inner container 350.

[0050] In some preferred embodiments, the sizes of the plurality of linkage pipes 331 gradually increase from the linkage pipe 331 close to the second ball mill inner container 350 to the linkage pipe 331 far away from the second ball mill inner container 350, wherein the inner diameter of each linkage pipe 331 gradually decreases from one end to the other end, so that the phosphorus pentasulfide crystals meeting the target size after rough ball milling are guided, thereby improving the transmission efficiency.

[0051] In addition, in order to facilitate the filtration of the phosphorus pentasulfide crystals after different rough ball milling, the filter baffle group 320 in the embodiment includes at least two filter discs which are rotatably connected to the middle part of the shell 310, and the filter holes on each filter disc have the same size, specifically, the filter baffle group 320 includes a first filter disc 321 and a second filter disc 322, the first filter disc 321 and the second filter disc 322 are rotatably connected, and the size of the gap between the filter holes on the first filter disc 321 and the filter holes on the second filter disc 322 is adjusted by rotating one of the first filter disc 321 and the second filter disc 322, and it should be noted that the first filter disc 321 and the second filter disc 322 are not limited to the number of filter discs in the filter baffle group 320, and other numbers of filter discs such as three, four, etc. can also be used, which are not particularly limited here.

[0052] In order to facilitate the adjustment of the filter aperture of the phosphorus pentasulfide crystals, in some preferred embodiments, the outer periphery of the first filter disc 321 and the second filter disc 322 exceeds the outer peripheral edge of the shell 310, that is, the edge of the first filter disc 321 and the edge of the second filter disc 322 are arranged outside the shell 310, so that the external workers can adjust the size of the gap between the filter holes on the first filter disc 321 and the filter holes on the second filter disc 322 by rotating the edge of the first filter disc 321 or the edge of the second filter disc 322, that is, the size of the filter aperture can be adjusted by adjusting the size of the gap.

[0053] It should be noted that in the embodiment, the first driving member 110 and the second driving member can both be servo motors in the prior art, and since the servo motor is a conventional prior art in the field, it will not be particularly described here, and the first ball mill inner container 340 and the second ball mill inner container 350 are respectively provided with a discharge port and a feeding port for feeding and discharging.

[0054] In summary, the first embodiment of the application provides a ball milling system applied to phosphorus pentasulfide, which has at least the following beneficial effects compared with the traditional ball mill:

[0055] In the ball milling system applied to the phosphorus pentasulfide provided in the application, one ball mill inner shell is fixedly connected to one side of the filter baffle group 320, so that when the driving device 100 drives the ball mill 300 to rotate relative to the support frame 200, the shell 310 in the ball mill 300 drives the ball mill inner shell to rotate horizontally, that is, the ball mill inner shell can be used for fine ball milling of the phosphorus pentasulfide crystals. In the ball milling of the initial phosphorus pentasulfide crystals, another ball mill inner shell is movably connected to the other side of the filter baffle group 320 through the transmission assembly 330, so that when the shell 310 rotates relative to the support frame 200, the transmission assembly 330 drives one end of the ball mill inner shell to rotate and reciprocate relative to the other ball mill inner shell. Therefore, the initial phosphorus pentasulfide crystals can be first put into the ball mill inner shell movably connected with the transmission assembly 330, and the ball mill inner shell can be used for coarse ball milling of the initial phosphorus pentasulfide crystals, that is, the crystals with different particle sizes are coarsely ground so as to meet the target size. In the ball milling process, the ball mill inner shell can be moved in the horizontal rotation, that is, when the ball mill inner shell is at an inclined angle, the phosphorus pentasulfide crystals in the ball mill inner shell can be filtered towards the filter baffle group 320, so that the phosphorus pentasulfide crystals meeting the target size are finely ground. In the ball milling of phosphorus pentasulfide crystals with different volumes, the initial phosphorus pentasulfide crystals can be first coarsely ground and then finely ground. Compared with the prior art in which one ball mill cavity is used for coarse and fine mixed ball milling, the ball milling system provided in the application can greatly improve the ball milling speed and reduce the probability of uneven distribution of the ground material particles, thereby guaranteeing the quality of the final product.
