Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, in particular to a continuous evaporation dryer. Background Art

[0002] The evaporation dryer is a new type of continuous drying equipment that integrates drying, crushing and screening. Existing evaporation dryers use hot air and material separation to improve drying efficiency, but most of them can only dry items that need to be crushed. When drying materials that do not need to be crushed, further crushing affects the material requirements, and the materials that do not need to be crushed cannot be dried. As a result, the existing evaporation dryers are only suitable for a single material, and the drying process requires timely observation by staff, and the degree of automation is low. Therefore, there is an urgent need for a dual-purpose evaporation dryer. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is as follows: a continuous evaporation dryer includes a feeding mechanism and a drying mechanism, wherein the feeding mechanism includes a feeding barrel and a feeding screw rod, a bottom plate is arranged at the bottom of the second bracket on the feeding barrel, a feeding pipe on the feeding barrel is connected with a feeding trough, a feeding screw rod is rotatably installed inside the feeding pipe, two groups of feeding bins are symmetrically arranged above the feeding barrel, the feeding bins are coaxial with the feeding barrel, two groups of sealing rings are symmetrically slidably installed on the feeding bins, and the two groups of sealing rings are in close contact; a knife assembly is rotatably installed on the third bracket of the bottom plate, and the knife assembly has no knife ring and the knife ring is located in the plane between the two groups of sealing rings On the upper part, the two groups of sealing rings slide back to back, and the knife assembly rotates to replace the knifeless ring and the knife ring between the sealing rings. The drying mechanism includes a drying cylinder and a collecting bin. The drying cylinder is fixedly installed on the second bracket. A feeding cylinder is arranged inside the drying cylinder. A connecting pipe is connected between the drying cylinder and the upper feeding bin above, and a through pipe is connected between the feeding cylinder and the collecting bin. Airflow disks are rotatably installed below the drying cylinder and the upper feeding cylinder respectively, and a plurality of air holes are arranged on the airflow disks. A drying airflow box is connected between the two groups of airflow disks through a three-way pipe. A storage box is arranged below the collecting bin, and the storage box is arranged on a disconnecting mechanism on the bottom plate. The disconnecting mechanism controls the start and stop of the drying airflow box.

[0004] Furthermore, the third bracket is provided with a tool changing mechanism, and the tool changing mechanism also includes a cylinder and a tool changing frame. The cylinder is fixedly mounted on the third bracket, and the tool changing frame is slidably mounted on the first sliding rod of the third bracket. The output end of the cylinder is fixedly mounted on the tool changing frame, and a tripod is provided on the tool changing frame. A sealing rod is provided on the sealing ring. The tripod is provided between two groups of sealing rods, and the tripod contacts and cooperates with the two groups of sealing rods. A sealing spring is provided between the sealing rod and the upper bin. When the cylinder contracts, it drives the tool changing frame to move toward the upper bin, drives the tripod to move toward the sealing rods of the two groups of sealing rings, pushes the two groups of sealing rods to drive the sealing rings to move in reverse, and the sealing spring is compressed, and the distance between the two groups of sealing rings increases, so that it is convenient to replace the knifeless ring and the knife ring.

[0005] Furthermore, the tool changing mechanism also includes a ratchet assembly, a ratchet is fixedly installed on the bottom of the knife assembly, the ratchet is rotatably installed on the third bracket, the ratchet assembly is rotatably installed on the third bracket, the ratchet assembly includes a tool changing gear and a pawl, the tool changing gear is rotatably installed on the third bracket, the tool changing gear is coaxial with the ratchet, a rack is provided on the tool changing frame, the rack is meshed with the tool changing gear, the pawl is rotatably installed inside the tool changing gear, and the pawl is in contact with the ratchet. When the cylinder contracts, it drives the tool changer to move toward the upper silo and drives the rack to move toward the tool changer gear. During this process, the distance between the two sets of sealing rings gradually increases, and the knife ring or knife ring without knife ring between the two sets of sealing rings is leaked. At this time, the rack drives the tool changer gear to drive the pawl to rotate, the pawl drives the ratchet to rotate, and the ratchet drives the knife assembly to rotate 180 degrees to complete the replacement of the knife ring and the knife ring without knife ring; the cylinder extends, driving the tool changer to move away from the upper silo. At this time, under the elastic action of the two sets of sealing springs, the two sets of sealing rings are driven to move toward each other. Since the pawl rotates on the tool changer gear, when the tool changer is away from the upper silo, the rack drives the tool changer gear to rotate in the opposite direction. Under the unidirectional restriction of the pawl, the ratchet is in a stationary state, that is, the knife assembly is in a stationary state until the cylinder returns to its initial position and the two sets of sealing rings are in close contact.

[0006] Furthermore, the rack drives the ratchet assembly to rotate, driving the ratchet to rotate by 180 degrees, so as to facilitate the conversion between the knife ring and the knife ring.

As the amount of dry material in the storage box increases, the support frame is driven to move downward, and the support spring is compressed.

[0008] Furthermore, the disconnection mechanism also includes a disconnection frame and a drying spring. The disconnection frame is slidably mounted on the rectangular frame of the drying airflow box. The folded corner at the bottom of the disconnection frame contacts and cooperates with the disconnection plate of the support frame. A touch rod is arranged on the disconnection frame. The drying spring is arranged between the touch rod and the rectangular frame. The touch rod contacts and cooperates with the switch of the drying airflow box. The drying airflow box delivers high-temperature airflow to the two groups of airflow discs through a three-way pipe. The high-temperature airflow passes through the airflow disc at the bottom of the upper barrel and passes the dry material through the knifeless ring or knife ring between the two groups of sealing rings, flows through the connecting pipe and enters the drying barrel and the over-material barrel. The high-temperature airflow output by the airflow disc at the bottom of the drying barrel performs secondary drying on the material, and the material that has been dried for the second time is transported to the collection bin through the through pipe and falls into the storage box. As the mass of the storage box increases, the support frame moves downward, and the support spring is compressed until the material in the support frame reaches the target value. The support frame drives the folded corner of the disconnection frame through the disconnection plate to drive the touch rod to move away from the switch, and the drying spring is compressed. At this time, the touch rod is disconnected from the switch, the drying airflow box is closed, and the high-temperature airflow is stopped from being delivered to the upper barrel and the drying barrel, and the loading and drying are stopped.

[0009] Furthermore, the inner diameter of the drying cylinder is R, the inner diameter of the feeding cylinder is r, and 1.5r≤R≤2r, so that the high-temperature airflow of the airflow disk at the bottom of the drying cylinder can transport the material to the inside of the feeding cylinder.

The knife ring 611 and the knife ring 612 are on the same plane. The knife ring 611 and the knife ring 612 are located between two sets of sealing rings 24. If the material needs to be crushed, the knife ring 612 is coaxial with the sealing ring 24. If the material does not need to be crushed, the knife ring 611 and the sealing ring 24 are coaxial. The cylinder 62 is fixedly mounted on the third bracket 13, and the knife changing frame 63 is slidably mounted on the first slide bar 131 of the third bracket 13.

At this time, under the elastic action of the two groups of sealing springs 25, the two groups of sealing rings 24 are driven to move toward each other. Since the pawl 642 rotates on the tool changer gear 641, when the tool changer 63 is away from the loading bin 23, the rack 631 drives the tool changer gear 641 to rotate in the opposite direction. Under the unidirectional limiting action of the pawl 642, the ratchet 613 is in a stationary state, that is, the knife assembly 61 is in a stationary state, until the cylinder 62 returns to its initial position and the two groups of sealing rings 24 are in close contact.

[0034] Working principle: As the airflow disk 51 rotates, under the action of the rotating high-temperature airflow, the materials in the upper cylinder 21 and the drying cylinder 31 rotate and rise, and are crushed when passing through the knife ring 612. It is determined whether the materials to be dried need to be crushed. If further crushing is required, the knife ring 612 is made coaxial with the sealing ring 24. If crushing is not required, the knife ring 611 is made coaxial with the sealing ring 24.

[0035] When the cylinder 62 contracts, it drives the tool changer 63 to move toward the upper bin 23, drives the tripod 632 to move toward the sealing rods 241 of the two sets of sealing rings 24, pushes the two sets of sealing rods 241 to drive the sealing rings 24 to move in reverse, the sealing spring 25 is compressed, and the distance between the two sets of sealing rings 24 increases. During this process, the tool changer 63 drives the rack 631 to move toward the tool changer gear 641, and the distance between the two sets of sealing rings 24 gradually increases, leaking out the knife ring 611 or knife ring 612 between the two sets of sealing rings 24. At this time, the rack 631 drives the tool changer gear 641 to drive the pawl 642 to rotate, the pawl 642 drives the ratchet 613 to rotate, and the rack 631 drives the ratchet assembly 64 to rotate, driving the ratchet 613 to rotate at an angle of 180 degrees, the ratchet 613 drives the knife assembly 61 to rotate 180 degrees, completing the replacement of the knife ring 612 and the knife ring 611; the cylinder 62 extends, driving the tool changer 63 to move away from the loading bin 23, and the tripod 632 moves away from the sealing rod 241. Under the elastic action of the two groups of sealing springs 25, the two groups of sealing rings 24 are driven to move toward each other. Since the pawl 642 rotates on the tool changer gear 641, when the tool changer 63 is away from the loading bin 23, the rack 631 drives the tool changer gear 641 to rotate in the opposite direction. Under the unidirectional restriction of the pawl 642, the ratchet 613 is in a stationary state, that is, the knife assembly 61 is in a stationary state, until the cylinder 62 returns to its initial position and the two groups of sealing rings 24 are in close contact.

[0036] The material is put into the feeding trough 212. At this time, the contact rod 431 contacts the switch 411, and the high-temperature airflow in the drying airflow box 41 is transported to the feeding cylinder 21 and the drying cylinder 31 respectively through the three-way pipe 42 and the airflow disk 51. The motor 54 is started, and the pulley 52 on the motor 54 and its output shaft drives the other two sets of pulleys 52 to rotate through the belt 55, thereby driving the two sets of airflow disks 51 to rotate, and the airflow disk 51 in the feeding cylinder 21 drives the pulley 1 531 fixed thereto to rotate, and under the transmission action of the conveyor belt 1 532, drives the main bevel gear 533 to rotate; the main bevel gear 533 is meshed with the slave bevel gear 534, the main bevel gear 533 drives the slave bevel gear 534 to rotate, and the slave bevel gear 534 drives the pulley 2 535 fixed thereto to rotate, and under the transmission action of the conveyor belt 2 536, drives the feeding screw rod 22 to rotate, and when the feeding screw rod 22 rotates, the material is transported from the feeding trough 212 to the inside of the feeding cylinder 21 through the feeding pipe 211.

[0037] The airflow disk 51 at the bottom of the upper barrel 21 outputs a high-temperature airflow, which transports the material in the upper barrel 21 through the upper bin 23 and the sealing ring 24 to the connecting pipe 36 and enters the drying barrel 31; the high-temperature airflow output by the airflow disk 51 at the bottom of the drying barrel 31 performs secondary drying on the material, and transports the material that has been dried for the second time to the inside of the feeding barrel 32, and the material is transported to the collecting bin 34 through the through pipe 33 and falls into the storage box 35.

[0038] As the mass of the material storage box 35 increases, the support frame 44 moves downward and the support spring 45 is compressed until the material in the support frame 44 reaches the target value. At this time, the disconnect plate 441 contacts the corner of the disconnect frame 43, and the support frame 44 drives the corner of the disconnect frame 43 through the disconnect plate 441 to drive the feeler rod 431 to move away from the switch 411. The drying spring 46 is compressed. At this time, the feeler rod 431 is disconnected from the switch 411, and the drying airflow box 41 is closed, and the high-temperature airflow is stopped from being delivered to the upper barrel 21 and the drying barrel 31. Loading and drying are stopped, and the staff is reminded to replace the material storage box 35.

[0039] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
