Description

Technical Field

[0001] The invention relates to the technical field of crushing and grinding, in particular to a planetary grinder for slurry grinding with a self-cleaning function. Background Art

[0002] Planetary grinding machine for slurry grinding is a kind of equipment used for particle grinding, which is commonly used in industrial fields such as powder grinding, pigment preparation, cosmetic production, etc. It adopts the principle of planetary motion to grind and mix the slurry with high-speed rotating grinding tank and ball mill.

[0003] A planetary grinder is generally composed of a main plate and several ball mills. When the main plate rotates, the ball mills revolve around the main plate while rotating around their own axes, performing planetary motion. Its working mode is named after the motion trajectory of planets in the solar system, that is, the planets revolve around the stars while rotating on their own axes.

[0004] On the working turntable, at the eccentric position of the middle fixed gear, four or two symmetrical ball mills are installed. When the turntable rotates (revolution), it drives the ball mill to rotate around the axis of rotation, and in the opposite direction of the turntable, forming a planetary motion. When the balls in the ball mill move together with the ball mill, they are affected by the superposition of the Coriolis force (i.e., the self-rotational deflection force), generating strong impact and friction. This combination of impact and friction allows the grinding balls in the jar to grind and mix the sample at high speed.

[0005] However, after grinding, the existing planetary grinders often need to disassemble the ball mill for cleaning because the slurry will stick to the inner wall of the ball mill, which is a cumbersome process and has low cleaning efficiency. In addition, the slurry will generate a lot of heat due to collision and friction with the balls in the ball mill during grinding. If the heat cannot be dissipated in time, the temperature of the slurry will easily be too high. Summary of the invention

[0006] The object of the present invention is to provide a planetary grinder for slurry grinding with a self-cleaning function to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: the planetary grinder includes a frame, a driving motor, a transmission mechanism, a grinding jar, a cleaning mechanism and a distribution mechanism, the transmission mechanism is fastened to the frame, the driving motor is transmission-connected to the transmission mechanism, the grinding jar is transmission-connected to the transmission mechanism, the cleaning mechanism is fastened to the frame, the cleaning mechanism is communicated with the grinding jar, the distribution mechanism is communicated with the cleaning mechanism, and the distribution mechanism is used to distribute the slurry.

[0008] The frame is fixed on the ground to provide a stable working environment for other mechanisms. The driving motor is the main power source, which is used to drive the transmission mechanism. The transmission mechanism can drive the grinding tank to revolve around the main axis while rotating around its own axis to perform planetary motion. There are four groups of grinding tanks, and grinding balls are loaded in the grinding tanks. When the grinding tanks rotate under the drive of the transmission mechanism, the grinding balls in the grinding tanks are affected by the superposition of Coriolis forces when moving together with the grinding tanks, generating strong impact force and friction force to grind the slurry. The cleaning mechanism is used to clean the inside of the grinding tank after grinding is completed to ensure the cleanliness of the inside, thereby preparing for subsequent grinding. The distribution mechanism is used to introduce slurry and water into the grinding tank for grinding and cleaning.

[0009] Furthermore, the transmission mechanism includes a fixed plate, a rotating plate, a gear set and a transmission shaft. The fixed plate is tightly connected to the frame, the fixed plate is located on both sides of the grinding jar, the rotating plate is rotatably connected to the fixed plate, the gear set is located on the side close to the driving motor, the gear set is transmission-connected to the grinding jar, the driving motor is tightly connected to the fixed plate, the output end of the driving motor is transmission-connected to the transmission shaft, the transmission shaft is rotationally connected to the fixed plate, and the transmission shaft is tightly connected to the rotating plate.

[0010] The fixed plate is fixed on the frame as the support of the transmission mechanism. During grinding, the driving motor starts and transmits the torque to the transmission shaft, thereby driving the rotating plate to rotate on the fixed plate and driving the gear set to move. The gear set is used to drive the grinding jar to rotate around the axis to form a planetary motion. The grinding balls in the grinding jar continuously collide and rub against the inner wall of the grinding jar under the combined action of centrifugal force and Coriolis force, thereby achieving sufficient grinding of the slurry.

[0011] Furthermore, the cleaning mechanism includes a water tank, a water outlet pipe and a return pipe. The water tank is firmly connected to the frame. A water pump is built into the water tank. The output end of the water pump is connected to the water outlet pipe. The water outlet pipe is connected to the distribution mechanism. One end of the return pipe is connected to the water tank, and the other end of the return pipe is connected to the distribution mechanism.

[0012] The planetary grinder of the present application has two working states: grinding and cleaning. When grinding is performed, the cleaning mechanism is used for cooling to cool the heat generated during grinding. The water pump in the water tank is started to guide water to the grinding tank through the water outlet pipe to cool the grinding tank, and the cooling water can return to the water tank through the return pipe for circulation. When cleaning is performed, the water pump in the water tank is started to pump water into the grinding tank through the water outlet pipe for cleaning, and the cleaning water is discharged through another channel and does not flow back into the water tank.

[0013] Furthermore, the distribution mechanism includes a liquid inlet plate, a liquid outlet plate and a diverter assembly, the liquid inlet plate is tightly connected to the fixed plate, the liquid inlet plate is connected to the water outlet pipe, the liquid inlet plate is rotatably connected to the transmission shaft, the liquid inlet plate is located at the feed end of the grinding tank, the liquid outlet plate is tightly connected to the fixed plate, the liquid outlet plate is connected to the return pipe, the liquid outlet plate is located at the discharge end of the grinding tank, the diverter assembly is connected to the grinding tank, and the diverter assembly is provided with two groups, the two groups of diverter assemblies are respectively located at both ends of the grinding tank, one group of diverter assemblies is used for liquid inlet, and the other group of diverter assemblies is used for liquid outlet; the liquid inlet plate is provided with a feed port and a water inlet, and the feed port and the water inlet are arranged alternately The feed port is connected to a slurry source, and the water inlet is connected to a water outlet pipe; a discharge port and a water outlet are provided on the liquid outlet plate, the discharge port and the water outlet are arranged alternately, and the water outlet is connected to a return pipe; a feed channel, a liquid inlet channel, a discharge channel and a liquid outlet channel are provided on the transmission shaft; one end of the feed channel is connected to the feed port, and the other end of the feed channel is connected to the diversion component, one end of the liquid inlet channel is connected to the water inlet, and the other end of the liquid inlet channel is connected to the diversion component, one end of the discharge channel is connected to the diversion component, and the other end of the discharge channel is connected to the discharge port, and the liquid outlet channel is respectively connected to the diversion component and the water outlet.

[0014] The liquid inlet plate is mounted on the transmission shaft and is located at the feed end of the grinder. It does not rotate with the transmission shaft, so as to facilitate the introduction of slurry and water into the grinding tank. The liquid outlet plate is fixed on the fixed plate at the discharge end and is also mounted on the transmission shaft to facilitate discharge. During grinding, the slurry enters the liquid inlet plate through the feed port and is introduced into the diverter assembly along the feed channel. The diverter assembly diverts the slurry to the grinding tank for grinding. When the grinding is completed, the slurry enters the discharge channel through the diverter assembly on the other side and is discharged through the discharge port. During cooling, water flows into the water inlet through the outlet pipe and flows into the diverter assembly along the liquid inlet channel. The diverter assembly diverts water to each grinding tank for cooling. The cooled water flows back to the water tank along the liquid outlet channel, the outlet and the return pipe in turn, realizing the self-circulation of the cooling water flow.

[0015] Furthermore, the grinding tank includes a tank body and a rotating shaft, the tank body is provided with a cooling flow channel, the rotating shaft is provided with a first flow channel and a second flow channel, the first flow channel is connected to the inner cavity of the tank body, and the second flow channel is connected to the cooling flow channel; the diversion component includes a liquid distribution plate and a diversion plate, the liquid distribution plate and the diversion plate are respectively fastened to the fixed plate, the liquid distribution plate is sleeved on the transmission shaft, the diversion plate is sleeved on the rotating shaft, the liquid distribution plate is provided with a feed ring channel and a water inlet ring channel, the diversion plate is provided with a material distribution ring channel and a water distribution ring channel, the feed ring channel is connected to the feed channel, the feed ring channel is connected to the material distribution ring channel through a material guide pipe, the material distribution ring channel is connected to the first flow channel, the water inlet ring channel is connected to the liquid inlet channel, the water inlet ring channel is connected to the water distribution ring channel through a liquid guide pipe, and the water distribution ring channel is connected to the second flow channel.

[0016] During grinding, the slurry passes through the feed ring, the material guide pipe, the distribution ring and the first flow channel in turn to enter the grinding tank for grinding. After grinding, the slurry is discharged through the diversion component on the other side; during cooling, the water flows through the water inlet ring, the liquid guide pipe, the water distribution ring and the second flow channel in turn to enter the cooling flow channel on the tank body. The cooling flow channel is arranged in a spiral shape around the tank body, which greatly increases the contact area with the tank body and improves the cooling effect. After passing through the cooling flow channel, the cooling water returns to the water tank through the diversion component on the other side.

[0017] Furthermore, a cleaning channel and an active cavity are provided on the tank body. The cleaning channel is connected to the cooling channel. A flushing assembly is provided in the active cavity. The flushing assembly includes a sliding block and a return spring. The sliding block is slidably connected to the active cavity. One end of the return spring is firmly connected to the inner wall of the active cavity, and the other end of the return spring is firmly connected to the sliding block.

[0018] After the grinding is completed, the flushing assembly on the tank body is started by increasing the speed of the driving motor. When the speed of the grinding tank is increased under the drive of the driving motor, the sliding block located in the movable cavity overcomes the elastic force of the return spring under the action of centrifugal force and slides along the movable cavity, so that the cleaning flow channel is connected with the inner cavity of the grinding tank, and the water flows into the cleaning flow channel through the cooling flow channel, and is thus sprayed into the grinding tank to flush the inner cavity of the grinding tank. During the grinding operation, the cleaning flow channel is not connected with the inner cavity of the tank body under the support of the return spring, so that water flows into the grinding tank during grinding. Cooling and cleaning are organically combined through the flushing assembly, and the flushing assembly is started by centrifugal force. No additional starting mechanism is required, and the inner cavity of the grinding tank can be cleaned without disassembling the grinding tank, thereby realizing self-cleaning of the grinding tank.

[0019] Furthermore, a regulating component is provided on the liquid distribution plate located on a side close to the driving motor, and the regulating component is used to regulate the water flow.

[0020] During grinding operations, different rotation speeds are often required to meet the grinding needs of different materials. However, when the rotation speed is increased, the collision and friction between the grinding balls in the grinding tank and the slurry will intensify, greatly increasing the heat generated during grinding. If the cooling efficiency cannot be controlled in real time according to the heat generated during grinding, it is easy for the slurry to accumulate a large amount of heat during grinding. For some heat-sensitive slurries, it is easy to destroy their activity. By adjusting the components to control the water flow entering the cooling channel in real time, the higher the rotation speed, the greater the flow rate, and the cooling efficiency can be automatically controlled according to the grinding speed.

[0021] Furthermore, the adjustment component includes an arc-shaped slider, an adjustment block, an adjustment spring and a support spring. An arc-shaped groove and a guide groove are provided on the liquid distribution plate. The arc-shaped slider is slidably connected to the arc-shaped groove, the adjustment block is slidably connected to the guide groove, one end of the adjustment spring is firmly connected to the inner wall of the guide groove, the other end of the adjustment spring is firmly connected to the adjustment block, the support spring is located on the side of the arc-shaped groove away from the adjustment block, the arc-shaped groove and the guide groove are connected by a pipeline, hydraulic oil is filled in the arc-shaped groove and the guide groove, a connecting flow channel is provided on the arc-shaped slider, and the connecting flow channel and the liquid guide tube are eccentrically arranged.

[0022] When the speed increases during grinding, because the liquid distribution disk is fixed on the rotating disk, it will rotate with the rotating disk. Under the action of centrifugal force, the adjusting block will slide outward along the guide groove, thereby compressing the adjusting spring and pressing the hydraulic oil in the guide groove into the arc groove on the other side through the pipeline. Under the action of pressure, the arc-shaped slider will slide to the other side along the arc groove and compress the supporting spring. Because the connecting flow channel on the arc-shaped slider is eccentrically arranged with the liquid guide tube, when the arc-shaped slider slides to one side along the arc groove, the overlapping area between the connecting flow channel and the liquid guide tube will increase, and the flow cross-section will increase accordingly, thereby increasing the water flow entering the cooling flow channel, thereby correspondingly improving the cooling effect; the cooling efficiency is automatically adjusted according to the speed during grinding, thereby ensuring the stability of the slurry during grinding.

[0023] Furthermore, the gear set includes a fixed gear, a transition gear and a planetary gear. The fixed gear is tightly connected to the fixed disk, the transition gear is rotationally connected to the rotating disk, the transition gear is meshed with the fixed gear, the planetary gear is rotationally connected to the rotating disk, the planetary gear is meshed with the transition gear, and the planetary gear is transmission connected to the grinding jar.

[0024] When the rotating disk rotates driven by the transmission shaft, it will drive the transition gear to rotate around the fixed gear, and then drive the planetary gear to rotate, realize the self-rotation of the planetary gear, form planetary motion, and thus drive the grinding jar connected to the planetary gear to do planetary motion.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: after grinding is completed, the flushing assembly on the tank body is started by increasing the speed of the driving motor, and when the speed of the grinding tank is increased under the drive of the driving motor, the sliding block located in the active cavity overcomes the elastic force of the reset spring under the action of centrifugal force, and slides along the active cavity, so that the cleaning flow channel is connected with the inner cavity of the grinding tank, and the water flows into the cleaning flow channel through the cooling flow channel, and is thereby sprayed into the grinding tank to flush the inner cavity of the grinding tank; during the grinding operation, under the support of the reset spring, the cleaning flow channel is not connected with the inner cavity of the tank body, thereby avoiding the entry of water during grinding; cooling and cleaning are organically combined through the flushing assembly, and the flushing assembly is started by centrifugal force, without the need for an additional starting mechanism, and the inner cavity of the grinding tank can be cleaned without disassembling the grinding tank, thereby realizing self-cleaning of the grinding tank.

[0026] When the speed increases during grinding, under the action of centrifugal force, the adjustment block will slide outward along the guide groove, thereby compressing the adjustment spring and pressing the hydraulic oil in the guide groove into the arc groove on the other side through the pipeline. Under the action of pressure, the arc-shaped slider will slide to the other side along the arc groove and compress the support spring. Because the connecting flow channel on the arc-shaped slider is eccentrically arranged with the liquid guide tube, when the arc-shaped slider slides to one side along the arc groove, the overlapping area between the connecting flow channel and the liquid guide tube will increase, and the flow cross section will increase accordingly, thereby increasing the water flow entering the cooling flow channel, thereby improving the cooling effect; it realizes automatic compensation of the cooling water flow according to the speed during grinding, thereby automatically adjusting the cooling efficiency and ensuring the stability of the slurry during grinding.

When the speed of the grinding tank 4 is increased under the drive of the driving motor 2, the sliding block 541 located in the active cavity 413 overcomes the elastic force of the reset spring 542 under the action of centrifugal force, and slides along the active cavity 413, so that the cleaning channel 412 is connected with the inner cavity of the grinding tank 4, and the water flows into the cleaning channel 412 through the cooling channel 411, and is thus sprayed into the grinding tank 4 to flush the inner cavity of the grinding tank 4; during the grinding operation, under the support of the reset spring 542, the cleaning channel 412 is not connected with the inner cavity of the tank body 41, thereby avoiding the entry of water during grinding; cooling and cleaning are organically combined through the flushing assembly 54, and the flushing assembly 54 is started by centrifugal force, without the need for an additional starting mechanism, and the inner cavity of the grinding tank 4 can be cleaned without disassembling the grinding tank 4, thereby realizing self-cleaning of the grinding tank 4.

[0055] like Fig.11 As shown, a regulating component 64 is provided on the liquid distribution plate 631 located on the side close to the driving motor 2, and the regulating component 64 is used to regulate the water flow.

[0056] During grinding operations, different rotation speeds are often required to meet the grinding requirements of different materials. However, when the rotation speed is increased, the collision and friction between the grinding balls in the grinding tank 4 and the slurry will intensify, which will greatly increase the heat generated during grinding. If the cooling efficiency cannot be controlled in real time according to the heat generated during grinding, it is easy for the slurry to accumulate a large amount of heat during grinding. For some heat-sensitive slurries, it is easy to destroy their activity. The water flow rate entering the cooling channel 411 is controlled in real time by adjusting the component 64. The higher the rotation speed, the greater the flow rate, thereby realizing automatic control of the cooling efficiency according to the grinding rotation speed.

[0057] like Fig.12As shown, the adjustment component 64 includes an arc-shaped slider 641, an adjustment block 642, an adjustment spring 643 and a support spring 644. The liquid distribution plate 631 is provided with an arc-shaped groove 6313 and a guide groove 6314. The arc-shaped slider 641 is slidably connected to the arc-shaped groove 6313, the adjustment block 642 is slidably connected to the guide groove 6314, one end of the adjustment spring 643 is tightly connected to the inner wall of the guide groove 6314, the other end of the adjustment spring 643 is tightly connected to the adjustment block 642, the support spring 644 is located on the side of the arc-shaped groove 6313 away from the adjustment block 642, the arc-shaped groove 6313 is connected to the guide groove 6314 through a pipeline, hydraulic oil is filled in the arc-shaped groove 6313 and the guide groove 6314, and a connecting flow channel 6411 is provided on the arc-shaped slider 641, and the connecting flow channel 6411 and the liquid guide tube 634 are eccentrically arranged.

[0058] When the speed increases during grinding, because the liquid distribution disk 631 is fixed on the rotating disk 32, it will rotate with the rotating disk. Under the action of centrifugal force, the adjustment block 642 will slide outward along the guide groove 6314, thereby compressing the adjustment spring 643 and pressing the hydraulic oil in the guide groove 6314 into the arc groove 6313 on the other side through the pipeline. Under the action of pressure, the arc slider 641 will slide to the other side along the arc groove 6313 and compress the support spring 644. Because the connecting flow channel 6411 on the arc slider 641 is eccentrically arranged with the liquid guide tube 634, when the arc slider 641 slides to one side along the arc groove 6313, the overlapping area between the connecting flow channel 6411 and the liquid guide tube 634 will increase, and the flow cross section will increase accordingly, thereby increasing the water flow entering the cooling flow channel 411, thereby correspondingly improving the cooling effect; the cooling efficiency is automatically adjusted according to the speed during grinding, and the stability of the slurry during grinding is guaranteed.

[0059] like Figure 3 As shown, the gear set 33 includes a fixed gear 331, a transition gear 332 and a planetary gear 333. The fixed gear 331 is tightly connected to the fixed disk 31, the transition gear 332 is rotationally connected to the rotating disk 32, the transition gear 332 is meshed with the fixed gear 331, the planetary gear 333 is rotationally connected to the rotating disk 32, the planetary gear 333 is meshed with the transition gear 332, and the planetary gear 333 is transmission connected to the grinding jar 4.

[0060] When the rotating disk 32 rotates driven by the transmission shaft 34, it will drive the transition gear 332 to rotate around the fixed gear 331, and then drive the planetary gear 333 to rotate, realize the self-rotation of the planetary gear 333, form a planetary motion, and thus drive the grinding jar 4 connected to the planetary gear 333 to perform planetary motion.

[0061] The working principle of the present invention is as follows: during grinding, the slurry enters the liquid inlet plate 61 through the feed port 611, and is introduced into the diverter assembly 63 along the feed channel 341. The diverter assembly 63 diverts the slurry to the grinding tank 4 for grinding. When the grinding is completed, the slurry enters the discharge channel 343 through the diverter assembly 63 on the other side, and is discharged through the discharge port 621. During cooling, the water flows into the water inlet 612 through the outlet pipe 52, and flows into the diverter assembly 63 along the liquid inlet channel 342. The diverter assembly 63 diverts the water flow to Each grinding tank 4 is cooled, and the cooled water flows back to the water tank 51 along the liquid outlet channel 344, the water outlet 622 and the return pipe 53 in turn, so as to realize the self-circulation of the cooling water flow; when the speed is increased during grinding, because the liquid distribution plate 631 is fixed on the rotating disk 32, it will rotate with the rotating disk. Under the action of centrifugal force, the adjusting block 642 will slide outward along the guide groove 6314, thereby compressing the adjusting spring 643, and pressing the hydraulic oil in the guide groove 6314 into the arc groove 6313 on the other side through the pipeline, Under the action of pressure, the arc-shaped slider 641 will slide along the arc-shaped groove 6313 to the other side and compress the support spring 644. Because the connecting flow channel 6411 on the arc-shaped slider 641 is eccentrically arranged with the liquid guide tube 634, when the arc-shaped slider 641 slides along the arc-shaped groove 6313 to one side, the overlapping area between the connecting flow channel 6411 and the liquid guide tube 634 will increase, and the flow cross section will increase accordingly, thereby increasing the water flow entering the cooling flow channel 411, thereby correspondingly improving the cooling effect; according to the rotation speed during grinding, Automatically adjust the cooling efficiency; after the grinding is completed, the flushing assembly 54 on the tank body 41 is started by increasing the speed of the driving motor 2. When the speed of the grinding tank 4 is increased under the drive of the driving motor 2, the sliding block 541 located in the active cavity 413 overcomes the elastic force of the return spring 542 under the action of centrifugal force, and slides along the active cavity 413, so that the cleaning flow channel 412 is connected with the inner cavity of the grinding tank 4, and the water flows into the cleaning flow channel 412 through the cooling flow channel 411, and is sprayed into the grinding tank 4 to flush the inner cavity of the grinding tank 4;
