Description

Technical Field

[0001] The invention relates to the field of drying equipment, in particular to a xanthate throwing type dryer. Background Art

[0002] Xanthate is an organic sulfur compound, also known as xanthate, which is widely used in various industries. For example, in the mining industry, xanthate can be used as a collecting agent, which plays an important role in the beneficiation and flotation of heavy metal sulfide ores. In the preparation process of xanthate, the powdered xanthate needs to be granulated by a granulating equipment, and then the xanthate particles are dried and dehydrated to obtain granular xanthate.

[0003] Related technologies can refer to the Chinese patent with announcement number CN114526589B, which discloses a dryer for producing ore dressing xanthate, belonging to the technical field of xanthate drying equipment, including a drying box, a xanthate feeding mechanism, a throwing mechanism, a first drying mechanism and a discharge pipe, wherein the xanthate feeding mechanism is arranged directly above the drying box, the throwing mechanism is arranged in the drying box, and the throwing mechanism is directly below the xanthate feeding mechanism, the first drying mechanism is arranged at the side end of the drying box, and the first drying mechanism is between the xanthate feeding mechanism and the throwing mechanism, and the discharge pipe is arranged on the drying box and on the opposite side of the first drying mechanism. The dryer can prevent the xanthate from being in a clumping state during the drying process, and the xanthate is broken up by the xanthate feeding mechanism, and then dried by the first drying mechanism, thereby improving the drying efficiency of the xanthate and improving the quality of the discharged xanthate.

[0004] With respect to the above-mentioned related technologies, in the process of driving xanthate to be scattered toward the discharge pipe by the spreading mechanism, when the contact position of the xanthate with the spreading blade is different, its initial velocity and angle when separated from the spreading blade are also different. For example, the xanthate particles at the edge of the spreading blade have a greater initial velocity when separated from the spreading blade than the xanthate particles close to the axis of the transmission wheel, and are therefore more easily thrown into the discharge pipe. For the xanthate particles that are also in granular form and not agglomerated, whether they can be discharged from the discharge pipe is mainly affected by their position. Therefore, no matter whether the moisture in the xanthate particles is dried or not, as long as they are in the appropriate position, there is a greater probability that they will be thrown out of the discharge pipe by the spreading blade, making it difficult to determine whether the xanthate particles are dried to the required degree, and the drying effect on the xanthate particles is poor. Summary of the invention

[0005] In order to improve the drying effect of xanthate particles, the present application provides a xanthate throwing dryer.

[0006] The present application provides a xanthate throwing dryer, which adopts the following technical solution:

[0007] A xanthate throwing type dryer comprises a drying cylinder, wherein the upper end of the drying cylinder is provided with a feed inlet, the lower end is provided with a discharge outlet, a hot air blower is fixedly arranged on the outer side of the drying cylinder, the hot air blower is connected with an air outlet duct, the air outlet duct passes through the drying cylinder and extends into the drying cylinder, and further comprises: a supporting cylinder, which is located in the drying cylinder and is fixedly connected to the drying cylinder along the vertical direction, the upper end of the supporting cylinder is coaxially connected with a throwing disc, the drying cylinder is provided with a rotating part for driving the throwing disc to rotate, the throwing disc is located directly below the feed inlet, the supporting cylinder is hollow, and a conveying port is provided at the lower end of the supporting cylinder, and a conveying member is arranged along the length direction, and the conveying member is used to drive the materials entering the supporting cylinder The xanthate particles in the cylinder are lifted to the top of the spreading plate; the collecting piece is located at the discharge port and is slidably connected to the drying cylinder vertically, the collecting piece is used to block the discharge port, and when the collecting piece blocks the discharge port, it guides the xanthate particles in the drying cylinder to move toward the conveying port, and when the collecting piece releases the blockage of the discharge port, it guides the xanthate particles to move toward the discharge port; the heating cylinder is sleeved on the outside of the supporting cylinder and fixedly connected to the supporting cylinder, the diameter of the heating cylinder is smaller than the diameter of the spreading plate, and a plurality of air outlets are evenly opened on the side of the heating cylinder away from the axis of the supporting cylinder, and the end of the air outlet pipe away from the hot air blower is fixedly connected to the heating cylinder and communicated with all the air outlets.

[0008] By adopting the above technical solution, xanthate particles are added into the drying cylinder from the feed port, so that the xanthate particles fall above the scattering disk, and the rotating part drives the scattering disk to rotate, so that the scattering disk drives the xanthate particles to scatter in the circumferential direction. The hot air blower delivers hot air into the heating cylinder through the air outlet pipe, and the hot air blows out from the exhaust hole to the scattered xanthate particles, thereby drying the xanthate particles. In the initial state, the collecting part blocks the discharge port. After the xanthate particles are dried by the heating cylinder, they fall to the lower end of the drying cylinder and flow to the conveying port under the action of the collecting part. After the xanthate particles enter the supporting cylinder, the conveying part drives the xanthate particles to be lifted to the upper end of the scattering disk for secondary scattering and drying. After the drying is completed, the collecting part removes the obstruction of the discharge port and guides the xanthate particles to be discharged from the discharge port. When the xanthate particles are dried, they are in a floating state, and their outer surface is completely exposed to the hot air, which is beneficial to improving the drying efficiency of the xanthate particles. At the same time, the rotation of the spreading disc drives the xanthate particles to fall evenly, reducing the probability of xanthate particles gathering. The xanthate particles are repeatedly spread and dried by setting a conveying member, which further improves the drying effect.

[0009] Optionally, the conveying member includes a conveying cylinder, a push plate and a pushing plate, the supporting cylinder is provided with a blocking member for controlling the closure of the conveying port, the conveying cylinder is located in the supporting cylinder and fits with the inner wall of the supporting cylinder, the push plate is vertically slidably connected to the supporting cylinder, the supporting cylinder is provided with a lifting member for driving the push plate to reciprocate along the axial direction, the pushing plate is located in the conveying cylinder and fits with the inner wall of the conveying cylinder, a push rod is fixed between the push plate and the pushing plate, the length of the push rod is greater than the length of the conveying cylinder, an elastic member 1 is provided between the conveying cylinder and the push plate, the elastic member 1 is used to push the conveying cylinder away from the push plate, the spreading plate is provided with a spreading port coaxial with the pushing plate, and the support cylinder is fixed with a stop ring corresponding to the conveying cylinder along the circumference of the spreading port.

[0010] By adopting the above technical solution, in the initial state, the conveying cylinder is located below the conveying port, at this time, the blocking member controls the conveying port to be opened, and the xanthate particles at the lower end of the drying cylinder pass through the conveying port into the support cylinder, and enter the conveying cylinder under the action of gravity, and the push plate supports the push plate through the push rod, so that the push plate and the conveying cylinder cooperate to form a barrel-shaped container for holding xanthate particles, and after the xanthate particles enter the conveying cylinder, the push plate is driven by the lifting member to approach the throwing disk, and the push plate is driven by the push rod to move the push plate when the push plate moves. At this time, under the action of the elastic member 1, the push plate drives the conveying cylinder to move synchronously with the push plate, and the blocking member closes the conveying port. After the push plate and the conveying cylinder cooperate to drive the xanthate particles to move to the upper end of the support cylinder in batches, the conveying cylinder contacts the stop ring, the push plate continues to move, and the elastic member 1 is deformed, so that the push rod drives the push plate to drive the xanthate particles to pass through the throwing port to move above the throwing disk, and the xanthate particles are uniformly collapsed toward the throwing disk by the action of gravity, so that the xanthate particles are evenly distributed when they contact the throwing disk.

[0011] Optionally, the blocking member includes an elastic member 2 and a baffle ring. The baffle ring is located below the conveying cylinder and is slidably connected to the supporting cylinder along the axial direction. The push plate is located between the conveying cylinder and the baffle ring. A baffle block adapted to the conveying port is fixedly provided on the upper end of the baffle ring. The supporting cylinder is provided with a slide groove connected to the conveying port. The baffle block is located in the slide groove and fits with the inner wall of the slide groove. The elastic member 2 is located between the baffle ring and the supporting cylinder, and is used to push the baffle ring to fit with the push plate.

[0012] By adopting the above technical solution, in the initial state, when the conveying pipe is located below the conveying port, the retaining ring contacts the push plate under the action of the second elastic member, at which time the retaining block is located in the slide groove, and the conveying port is in an open state. When the push plate drives the conveying cylinder to move upward, the second elastic member drives the retaining ring close to the throwing plate, and when the retaining ring moves, it drives the retaining block to close the conveying port, thereby preventing the xanthate particles from entering the support cylinder after the conveying cylinder moves upward.

[0013] Optionally, the lifting member includes a lifting screw, a driving motor and a sealing plate. The supporting cylinder has a limiting groove along the axial direction. The lifting screw is located in the limiting groove and is rotatably connected to the supporting cylinder. The driving motor is fixedly connected to the supporting cylinder to drive the lifting screw to rotate. The push plate is fixedly connected with a slider, the slider is located in the limiting groove and fits with the inner wall of the limiting groove. The lifting screw passes through the slider and is threadedly connected to the slider. The sealing plate is located in the slide groove and is slidably connected to the slider along the length direction of the slide groove. An elastic member three is provided between the sealing plate and the slider, and the elastic member three is used to push the sealing plate close to the spreading plate.

[0014] By adopting the above technical solution, the support cylinder limits the slider through the limit groove. When the driving motor drives the lifting screw to rotate, the lifting screw pushes the slider to move along the limit groove, and the slider moves to drive the push plate to move. In the initial state, the sealing plate extends from the upper end of the conveying cylinder under the action of the elastic member 3 and blocks the limit groove. When the slider drives the sealing plate to collide with the support cylinder, the sealing plate stops and generates relative displacement with the conveying cylinder. The sealing plate is conducive to reducing the probability of xanthate particles entering the limit groove.

[0015] Optionally, the rotating part includes a rotating motor and a transmission rod. A swivel is fixedly provided at the lower end of the spreading disc. The swivel is sleeved on the outside of the supporting cylinder, and a plurality of gear blocks are fixedly provided on the inner wall of the swivel along the circumferential direction. The transmission rod is arranged along the axial direction of the supporting cylinder and is rotatably connected to the supporting cylinder. A gear 1 meshing with the gear block is coaxially fixedly provided on the upper end of the transmission rod. The rotating motor is fixedly connected to the drying cylinder, and the output shaft of the rotating motor passes through the drying cylinder and is coaxially fixed to the transmission rod.

[0016] By adopting the above technical solution, when the rotating motor drives the transmission rod to rotate, the transmission rod drives the rotating ring to rotate through the engagement of gear 1 and the tooth block. When the rotating ring rotates, it drives the spreading disk to rotate, so that the spreading disk drives the xanthate particles to be spread.

[0017] Optionally, a pushing ring is sleeved on the lower end of the support tube, and the pushing ring is rotatably connected to the support tube along the circumferential direction. A spiral plate is fixed on the outer edge of the pushing ring. When the pushing ring rotates, the spiral plate drives the xanthate particles to approach the support tube. A gear ring is fixed on the side of the pushing ring close to the axis of the support tube, and a transmission rod is coaxially fixed with a gear 2, which passes through the support tube and meshes with the gear ring.

[0018] By adopting the above technical solution, when the transmission rod rotates, the meshing of gear 2 and the gear ring drives the push ring to rotate, and when the push ring rotates, it drives the spiral plate to move, so that the spiral plate drives the xanthate particles in the circumference of the support tube to move. When the xanthate particles are directly opposite to the conveying port, the xanthate particles pass through the conveying port into the support tube. The spiral blades are helpful to reduce the xanthate particles gathered at the lower end of the support tube.

[0019] Optionally, the collecting member includes a guide ring and a lifting cylinder, a support platform is fixedly provided in the drying cylinder, the support cylinder is located at the upper end of the support platform and is fixedly connected to the support platform, one end of the discharge port is located at the outer edge of the support platform along the circumferential direction, and the other end extends to the outside of the drying cylinder, and a collection box opposite to the discharge port is fixedly provided on the outside of the drying cylinder, the guide ring is sleeved on the outside of the support platform and is slidably connected to the support platform along the axis direction of the support platform, a guide surface is provided on the upper end of the guide ring, the guide surface points along the outer circle of the support cylinder to the direction of the axis and is inclined from top to bottom, and the lifting cylinder is fixedly connected to the drying cylinder for driving the guide ring to move.

[0020] By adopting the above technical scheme, the support table supports the support cylinder. In the initial state, the guide ring is close to the support cylinder. At this time, the guide surface is flush with the upper end surface of the support table. When the xanthate particles fall on the guide ring, they slide along the guide surface toward the support cylinder. When the drying is completed, the guide ring is driven downward by the lifting cylinder. When the lower end of the guide ring is directly opposite to the discharge port, the xanthate particles that fall on the guide ring enter the discharge port along the guide surface and converge to the collection box along the discharge port, thereby improving the convenience of taking out the xanthate particles from the drying cylinder.

[0021] Optionally, a plurality of guide plates are fixedly provided in the drying cylinder along the axial direction, the guide plates are evenly arranged along the circumference of the heating cylinder, the gap between the guide plates and the heating cylinder forms an annular opening, and the guide plates are arranged obliquely from top to bottom along the outer circle pointing in the direction of the axis.

[0022] By adopting the above technical solution, the xanthate particles are deviated away from the heating cylinder under the action of hot air, and fall on the guide plate under the action of gravity. At this time, the guide plate guides the xanthate particles to approach the heating cylinder again, which is beneficial to improve the drying efficiency of the xanthate particles.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Add xanthate particles into the drying cylinder from the feed port, so that the xanthate particles fall onto the top of the scattering plate. The rotating part drives the scattering plate to rotate, so that the scattering plate drives the xanthate particles to scatter in the circumferential direction. The hot air blower delivers hot air into the heating cylinder through the air outlet pipe, and the hot air blows out from the exhaust hole toward the scattered xanthate particles, thereby drying the xanthate particles. In the initial state, the collecting part blocks the discharge port. After being dried by the heating cylinder, the xanthate particles fall to the lower end of the drying cylinder, and flow toward the conveying port under the action of the collecting part. After the xanthate particles enter the supporting cylinder, the conveying part drives the xanthate particles to be lifted to the upper end of the scattering plate for secondary scattering and drying. After the drying is completed, the collecting part removes the obstruction of the discharge port and guides the xanthate particles to be discharged from the discharge port. When the xanthate particles are dried, the xanthate particles are in a floating state, and their outer surface is completely exposed to the hot air, which is beneficial to improving the drying efficiency of the xanthate particles. At the same time, the xanthate particles are evenly scattered when the spreading disc rotates, which reduces the probability of xanthate particles gathering. In addition, the xanthate particles are repeatedly scattered and dried by setting a conveying member, which further improves the drying effect.

[0025] 2. In the initial state, the conveying cylinder is located below the conveying port. At this time, the blocking member controls the conveying port to open. The xanthate particles at the lower end of the drying cylinder pass through the conveying port into the support cylinder, and enter the transport cylinder under the action of gravity. The push plate supports the push plate through the push rod, so that the push plate and the transport cylinder cooperate to form a barrel-shaped container for holding xanthate particles. After the xanthate particles enter the transport cylinder, the lifting member drives the push plate to approach the throwing plate. When the push plate moves, the push plate drives the push plate to move. At this time, under the action of the elastic member 1, the push plate drives the conveying cylinder to move synchronously with the push plate. At this time, the blocking member closes the conveying port. After the push plate and the conveying cylinder cooperate to drive the xanthate particles to move to the upper end of the support cylinder in batches, the conveying cylinder contacts the stop ring, the push plate continues to move, and the elastic member 1 deforms, so that the push rod drives the push plate to drive the xanthate particles to pass through the throwing port to move above the throwing plate, and the xanthate particles collapse evenly toward the throwing plate through the action of gravity, so that the xanthate particles are evenly distributed when they contact the throwing plate.

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] The embodiment of the present application discloses a xanthate throwing dryer.

[0034] Example:

[0035] Reference Figure 1 and Figure 2 A xanthate throwing dryer comprises a drying cylinder 1, which is hollow and provided with a support cylinder 2 in the drying cylinder 1, and the support cylinder 2 is located at the lower end of the drying cylinder 1. A support platform 17 is fixed in the support cylinder 2, and the support platform 17 is coaxial with the support cylinder 2. The support cylinder 2 is fixedly connected to the upper end surface of the support platform 17 and is coaxial with the support platform 17. A through hole is opened in the support cylinder 2 along the axial direction, and a conveying port 22 connected with the through hole is opened at the lower end of the support cylinder 2.

[0036] Reference Figure 2 and Figure 3 The upper end of the support platform 17 is provided with an arc groove 171, which is inclined from top to bottom along the outer circle of the support platform 17 pointing to the support cylinder 2. A collecting member 4 is also provided in the drying cylinder 1, and the collecting member 4 includes a guide ring 41 and a lifting cylinder 42. The lower end of the drying cylinder 1 is provided with an annular groove along the circumference of the support platform 17. The guide ring 41 is located in the annular groove and is slidably connected to the drying cylinder 1 along the axial direction.

[0037] Reference Figure 2 and Figure 3The guide ring 41 is tilted from top to bottom along the direction of the outer circle pointing to the diameter. The lifting cylinder 42 is fixedly connected to the drying drum 1 to drive the guide ring 41 to move. The lower end of the drying drum 1 is provided with a discharge port 12. One end of the discharge port 12 is connected to the annular sink groove, and the other end extends to the outer wall of the drying drum 1. The outer side of the drying drum 1 is fixed with a collection box 15 adapted to the discharge port 12. In the initial state, the guide ring 41 is in an ascending state driven by the lifting cylinder 42. At this time, the guide ring 41 is above the discharge port 12 and blocks the discharge port 12.

[0038] Reference Figure 2 and Figure 3 The upper end of the support cylinder 2 is connected with a spreading disc 21 in a circumferential rotation, and the spreading disc 21 is coaxially arranged with the support cylinder 2. The drying cylinder 1 is provided with a rotating member 14 for driving the spreading disc 21 to rotate. The rotating member 14 includes a rotating motor 141 and a transmission rod 142. The support cylinder 2 is vertically provided with a rotating hole 1, and the transmission rod 142 is located in the rotating hole 1 and is rotatably connected with the support cylinder 2. The rotating motor 141 is installed at the lower end of the drying cylinder 1, and is used to drive the transmission rod 142 to rotate.

[0039] Reference Figure 3 and Figure 4 A gear 143 is coaxially fixed to the upper end of the transmission rod 142. When the transmission rod 142 rotates, the gear 143 is driven to rotate. A rotating ring 212 is coaxially fixed to the lower end of the spreading plate 21. The rotating ring 212 is sleeved on the outer side of the support tube 2, and a plurality of tooth blocks meshing with the gear 143 are evenly fixed on the inner wall of the rotating ring 212 along the circumferential direction. Under the connection between the tooth blocks and the rotating ring 212, when the gear 143 rotates, the spreading plate 21 is driven to rotate.

[0040] Reference Figure 2 and Figure 3 A heating cylinder 5 is fixedly arranged outside the support cylinder 2, and dense air outlet holes 51 are evenly opened on the outer edge of the heating cylinder 5 along the circumferential direction. A hot air blower 13 is installed outside the drying cylinder 1, and the hot air blower 13 is connected to an air outlet pipe 131, which passes through the drying box and is connected to the heating cylinder 5. When the hot air blower 13 is working, high-temperature gas is transported into the heating cylinder 5 through the air outlet pipe 131, and the high-temperature gas is evenly discharged from the air outlet holes 51.

[0041] Reference Figure 2 A feed port 11 is provided at the upper end of the drying cylinder 1, and the feed port 11 is directly opposite to the scattering plate 21. Xanthate particles are fed into the drying cylinder 1 through the feed port 11. When the xanthate particles come into contact with the scattering plate 21 under the action of gravity, the scattering plate 21 drives the xanthate particles to fall evenly along its own circumference through the action of centrifugal force. During the process of the xanthate particles falling to the lower end of the drying cylinder 1, the xanthate particles pass through the heating cylinder 5, so that the heating cylinder 5 dries the xanthate particles through the high-temperature airflow.

[0042] Reference Figure 2 and Figure 3 A plurality of guide plates 16 are fixedly arranged in the drying cylinder 1. The plurality of guide plates 16 are evenly distributed vertically. The guide plates 16 are arranged circumferentially along the heating cylinder 5 and are inclined from top to bottom along the outer circle of the drying cylinder 1 toward the axis. When the xanthate particles move away from the heating cylinder 5 under the push of the airflow, they approach the guide plates 16. Under the action of gravity, the xanthate particles contact the guide plates 16 and then approach the heating cylinder 5 again along the guide plates 16, and continue to fall through the gap between the heating cylinder 5 and the wire plate. The provision of the guide plates 16 is conducive to extending the falling time of the xanthate particles and improving the drying efficiency of the xanthate particles.

[0043] Reference Figure 3 and Figure 4 , when the xanthate particles fall into the drying drum 1 (reference Figure 2 ) When the lower end of the support tube 17 is in contact with the guide ring 41, the xanthate particles move along the guide ring 41 toward the arc groove 171 of the support platform 17. After entering the arc groove 171, the xanthate particles collide with the support tube 2 under the guidance of the inner wall of the arc groove 171. The outer circle of the support tube 2 is connected to the push ring 26 for axial rotation. The outer circle of the push ring 26 is fixedly connected to the spiral plate. When the push ring 26 rotates, the spiral plate is driven to rotate. The spiral plate is located in the arc groove 171 and is used to push the xanthate particles in the arc groove 171 to move circumferentially around the support tube 2.

[0044] Reference Figure 3 and Figure 4 The push ring 26 is coaxially fixed with a toothed ring 262, and the transmission rod 142 is coaxially fixed with a gear 2 144 meshing with the geared ring 262. When the transmission rod 142 rotates, the gear 2 144 is driven to rotate, so that the gear 2 144 drives the push ring 26 to rotate through the toothed ring 262, so that the push ring 26 drives the spiral plate to rotate around the outer circle of the support tube 2. After the xanthate particles come into contact with the spiral blade 261, the spiral blade 261 exerts a force on the xanthate particles to approach the axis of the support tube 2 during the rotation process.

[0045] Reference Figure 3 and Figure 4 The support cylinder 2 is provided with a conveying member 3, which includes a conveying cylinder 31, a push plate 32 and a push plate 33. The conveying cylinder 31 is located in the through hole, and the outer edge of the conveying cylinder 31 is in contact with the inner wall of the through hole. The support cylinder 2 limits and guides the conveying cylinder 31 through the through hole, so that the conveying cylinder 31 moves along the axis direction of the through hole. The push plate 33 is located in the conveying cylinder 31 and is slidably connected with the conveying cylinder 31 along the axis direction of the conveying cylinder 31.

[0046] Reference Figure 3 and Figure 5The push plate 32 is located at the lower end of the push plate 33 and is slidably connected to the support cylinder 2 in the vertical direction. A push rod 321 is fixedly arranged at the upper end of the push plate 32. The push rod 321 is fixedly connected to the push plate 33, and the length of the push rod 321 is greater than the length of the transport cylinder 31. When the push plate 32 moves, the push plate 33 is driven to move by the push rod 321. A sliding rod 312 is fixedly arranged at the lower end of the transport cylinder 31. The sliding rod 312 passes through the push plate 32 and is slidably connected to the push plate 32. An elastic member 311 is arranged between the push plate 32 and the transport cylinder 31. The elastic member 311 is a spring. One end of the spring is fixedly connected to the sliding rod 312, and the other end is fixedly connected to the push plate 32. In the natural state, the elastic member 311 pushes the transport cylinder 31 away from the push plate 32. Under the connection between the sliding rod 312 and the elastic member 311, the push plate 32 drives the transport cylinder 31 to move when it moves.

[0047] Reference Figure 2 and Figure 4 Under the action of the spiral blade 261 and gravity, the xanthate particles at the bottom of the drying cylinder 1 pass through the conveying port 22 into the support cylinder 2, and fall into the transport cylinder 31 to contact the push disk 33. When the push plate 32 moves along the axial direction of the support cylinder 2, the xanthate particles in the support cylinder 2 are driven to move through the transport cylinder 31 and the push disk 33. The support cylinder 2 is provided with a lifting member for driving the push plate 32 to move, and the lifting member includes a lifting screw 231, a driving motor 232 and a sealing plate 233. The inner wall of the support cylinder 2 is provided with a limiting groove along the axial direction, and the push plate 32 is fixed with a slider 322 adapted to the limiting groove. The slider 322 is inserted into the limiting groove and is slidably connected to the support cylinder 2 along the length direction of the limiting groove.

[0048] Reference Figure 2 and Figure 4 The lifting screw 231 is located in the limiting groove and is rotatably connected with the support cylinder 2, and the lifting screw 231 passes through the slider 322 and is threadedly connected with the slider 322. When the lifting screw 231 rotates, the slider 322 is driven to move along the limiting groove, so that the slider 322 drives the push plate 32 to move synchronously. The driving motor 232 is installed at the lower end of the drying cylinder 1, and is used to drive the lifting screw 231 to rotate. The sealing plate 233 is located in the limiting groove and is slidably connected with the slider 322 along the length direction of the limiting groove. An elastic member 3 234 is provided between the sealing plate 233 and the slider 322. The elastic member 3 234 is a spring, one end of the spring is fixedly connected with the sealing plate 233, and the other end is fixedly connected with the slider 322. When the elastic member 3 234 is in a natural state, the upper end of the sealing plate 233 is higher than the upper end of the transport cylinder 31. At this time, the sealing plate 233 blocks the limiting groove, thereby reducing the probability of xanthate particles entering the limiting groove when passing through the transport port.

[0049] Reference Figure 2 and Figure 5The support tube 2 is provided with a blocking member 6, which includes an elastic member 2 61 and a retaining ring 62. The retaining ring 62 is located at the lower end of the push plate 32 and is vertically slidably connected to the support tube 2. The elastic member 2 61 is located between the retaining ring 62 and the support tube 2. The elastic member 2 61 is also a spring, one end of which is fixedly connected to the support tube 2, and the other end is fixedly connected to the retaining ring 62. The elastic member 2 61 drives the retaining ring 62 to approach the conveying port 22 in a natural state. The support tube 2 is vertically provided with a chute 25 connected to the conveying port 22. A retaining block 63 adapted to the chute 25 is fixedly provided at the upper end of the retaining ring 62, and the width of the retaining plate is adapted to the conveying port 22.

[0050] Reference Figure 2 and Figure 5 When the transport cylinder 31 is at the lower end of the delivery port 22, the push plate 32 is at a position away from the scattering disc 21, and the baffle ring 62 contacts the push plate 32 under the action of the second elastic member 61, so that the baffle ring 62 is at a position away from the delivery port 22. At this time, the baffle 63 is located in the chute 25, and the delivery port 22 is in an open state. When the xanthate particles in the drying cylinder 1 reach a predetermined number, the lifting member drives the push plate 32 to move toward the scattering disc 21. When the push plate 32 moves, it drives the push plate 33 and the transport cylinder 31 to move synchronously, so that the push plate 33 cooperates with the transport cylinder 31 to drive the xanthate particles in the support cylinder 2 to move toward the scattering disc 21. When the push plate 32 approaches the scattering disc 21, the baffle ring 62 approaches the delivery port 22 under the drive of the second elastic member 61, so that the baffle ring 62 drives the baffle 63 to block the delivery port 22.

[0051] Reference Figure 2 and Figure 4 , the throwing plate 21 is vertically opened with a throwing port 211 adapted to the push plate 33, and the support cylinder 2 is fixedly connected with a stop ring 24 adapted to the transport cylinder 31. When the transport cylinder 31 approaches the throwing plate 21, the sealing plate 233 first contacts the stop ring 24, and at this time, the push plate 32 drives the transport cylinder 31 to continue to move, so that the sealing plate 233 and the transport cylinder 31 are relatively displaced, and the elastic member 3 234 is gradually stretched. When the transport cylinder 31 contacts the stop ring 24, the push plate 32 continues to move upward, and then drives the push plate 33 to continue to move through the push rod 321, so that the push plate 33 drives the xanthate particles in the transport cylinder 31 to be discharged from the throwing port 211.

[0052] Reference Figure 2 and Figure 4 The upper end surface of the push disk 33 is tilted from top to bottom along the direction of the axis pointing to the outer circle. When the height of the xanthate particles is higher than the height of the upper end surface of the scattering disk 21, the xanthate particles collapse along the circumference of the scattering disk 21 under the action of gravity and are evenly scattered under the action of the scattering disk 21. The scattered xanthate particles are dried again when passing through the heating cylinder 5, which is conducive to further improving the drying efficiency of the xanthate particles.

[0053] Reference Figure 1 and Figure 2 After the xanthate particles are dried, the guide ring 41 is driven downward by the lifting cylinder 42, so that the discharge port 12 is connected with the cavity in the drying cylinder 1 through the annular trough. When the xanthate particles contact the guide ring 41 again after being thrown, they are discharged from the drying cylinder 1 along the guide ring 41 to the discharge port 12, and slide into the collecting box 15, thereby completing the drying of the xanthate particles.

[0054] The working principle of a xanthate sprinkling dryer according to an embodiment of the present application is as follows: xanthate particles are added into the drying cylinder 1 through the feed port 11, and the rotating motor 141 drives the sprinkling disc 21 to rotate through the transmission rod 142. When the xanthate particles come into contact with the sprinkling disc 21, the sprinkling disc 21 drives the xanthate particles to be evenly sprinkled along its own circumference. Under the action of gravity, the xanthate particles fall toward the lower end of the drying cylinder 1 and pass through the heating cylinder 5. At this time, the hot air blower 13 delivers a high-temperature airflow into the heating cylinder 5 through the air outlet pipe 131. The high-temperature airflow is guided by the air outlet 51 and then blown toward the suspended xanthate particles. The xanthate particles are dried by the high-temperature airflow, and the xanthate particles are completely in contact with the high-temperature airflow, which is beneficial to improving the drying effect of the xanthate particles. Since the diameter of the xanthate particles is uniform, when the temperature of the high-temperature air flow blown out by the hot air blower 13 is a fixed value, the drying time required for the xanthate particles to meet the drying requirements is also a fixed value, such as 30 minutes, 60 minutes, etc. When the xanthate particles fall to the lower end of the drying cylinder 1, if the required drying time is not reached, the xanthate particles are guided into the supporting cylinder 2 through the collecting part 4, and the xanthate particles are driven by the transport part to move to the spreading plate 21 again, thereby realizing multiple drying of the xanthate particles and further improving the drying effect of the xanthate particles.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
