Description

Technical Field

[0001] The invention relates to the technical field of material transportation, in particular to an anti-agglomeration lifting and feeding mechanism and a disc dryer. Background Art

[0002] Disc dryer is a kind of equipment that uses heat energy to dry materials. Its working principle is to heat air or hot steam, stir and turn the materials so that they are fully in contact with the hot air flow, thereby achieving drying.

[0003] The operating temperature range of the disc dryer depends on the nature of the material being dried and the required degree of drying. Generally speaking, the operating temperature range is wider to meet the drying needs of different materials.

[0004] When drying materials, the wet materials need to be transported to the dryer through conveying equipment. However, when the existing conveying equipment transports materials with high humidity, as the materials move, the materials come into contact with each other and will agglomerate. The existing conveying equipment has a single feed inlet to the dryer and cannot be adjusted accordingly according to the material form. The agglomerated materials cannot be crushed before entering the dryer, resulting in poor material drying effect. Summary of the invention

[0005] The object of the present invention is to provide an anti-agglomeration lifting and feeding mechanism and a disc dryer to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An anti-agglomeration lifting and feeding mechanism is connected to a lifting and supporting plate, on which a drying kettle is fixed, comprising:

[0008] A conveying pipe is fixedly mounted on the lifting plate and connected to the drying kettle, and a side wall of the conveying pipe is connected to a material feeding hopper;

[0009] Also includes:

[0010] A crushing pipe is arranged on the side wall of the conveying pipe, and a conveying assembly connected with the crushing pipe and the drying kettle is arranged in the conveying pipe, and the conveying assembly can convey the material to the drying kettle through the crushing pipe;

[0011] A pump air pushing mechanism is arranged in the crushing tube, and a clumping crushing mechanism connected to the pump air pushing mechanism is also arranged in the crushing tube. The pump air pushing mechanism can crush the material in the crushing tube through the clumping crushing mechanism and blow the crushed material into the drying kettle.

[0012] As a further solution of the present invention: the conveying assembly includes a first discharge pipe and a second discharge pipe fixedly installed on the conveying pipe, the first discharge pipe is connected to the drying kettle, the second discharge pipe is connected to the crushing pipe, and a connecting pipe connected to the drying kettle is fixed on the circumferential outer wall of the crushing pipe.

[0013] As a further solution of the present invention: the pump air pushing mechanism includes a partition fixedly installed in the crushing tube, a plurality of air supply pipes equidistantly distributed in a circle are fixed on the partition, and a driving component connected to the partition is arranged in the crushing tube.

[0014] As a further solution of the present invention: the driving assembly includes a second motor fixedly installed at the end of the crushing tube, a second transmission rod connected to the output shaft of the second motor is rotatably installed in the crushing tube, a first annular groove is provided on the circumferential outer wall of the second transmission rod, and a guide structure connected to the second transmission rod is provided in the crushing tube.

[0015] As a further solution of the present invention: the guide structure includes a guide column fixedly installed in the crushing tube and fixedly connected to the partition, a piston disk slidably connected to the second transmission rod is slidably installed on the guide column, and a limit block slidably connected to the first annular groove is fixed on the inner wall of the piston disk.

[0016] As a further solution of the present invention: the agglomeration crushing mechanism includes a fixed crushing leaf fixedly mounted on the second transmission rod, the fixed crushing leaf is provided with a plurality of first grooves distributed at equal distances, a movable crushing leaf cooperating with the fixed crushing leaf is slidably mounted on the second transmission rod, the movable crushing leaf is provided with a plurality of second grooves distributed at equal distances, and a follow-up translation component connected to the movable crushing leaf is provided on the partition plate.

[0017] As a further solution of the present invention: the follow-up translation assembly includes a fixed sleeve fixedly installed on the partition, the circumferential outer wall of the fixed sleeve is provided with a second annular groove, and the movable crushing leaf is fixed with a limiting column slidably connected to the second annular groove.

[0018] A disc dryer, comprising:

[0019] A plurality of first heating disks and second heating disks are equidistantly and staggeredly distributed, wherein the first heating disks and the second heating disks are fixedly connected to the drying kettle, and a rake-dried mechanism cooperating with the first heating disks and the second heating disks is arranged in the drying kettle.

[0020] As a further solution of the present invention: the rake drying mechanism includes a first motor fixedly mounted on the bottom of the drying kettle, a first transmission rod connected to the output shaft of the first motor is rotatably mounted in the drying kettle, and a driven assembly is arranged on the first transmission rod.

[0021] As a further solution of the present invention: the driven assembly includes a plurality of first supporting sleeves and second supporting sleeves fixedly mounted on the first transmission rod and equidistantly and staggeredly distributed, the first supporting sleeve is fixed with a plurality of first rake blades equidistantly distributed around the circumference, and the second supporting sleeve is fixed with a plurality of second rake blades equidistantly distributed around the circumference.

[0022] Compared with the prior art, the beneficial effect of the present invention is that the present application can adjust the feed inlet according to the humidity of the material to crush the agglomerated material with high humidity, thereby ensuring a better subsequent drying effect. Specifically, when the humidity of the material is too high and agglomerates, the material is transported to the crushing tube under the action of the conveying component, and the agglomerated material is crushed under the action of the pump air pushing mechanism and the agglomeration crushing mechanism, and then the crushed material is transported to the drying kettle, ensuring that the material is in a loose state before the rake drying mechanism dries the material, thereby avoiding the agglomeration of the material resulting in the agglomerated material not being dried inside.

[0023] When the pump air pushing mechanism is pumping air, it can not only blow the material, but also blow and stir the material to a certain extent under the action of air flow stirring, so as to ensure that the crushed material will not clump again due to accumulation.

[0024] When the wet material is continuously added to the heating plate of the drying kettle through the first discharge pipe or the connecting pipe, the rake arm with rakes rotates inside the drying kettle, so that the rakes continuously turn the material. This turning action not only helps to evenly distribute the material on the heating plate, but also promotes heat exchange between the material and the heating medium, thereby improving the drying efficiency.

[0025] The heating medium enters from one end of the first heating plate and the second heating plate, and is discharged from the other end after heat exchange in the plate. This design enables the first heating plate and the second heating plate to quickly transfer heat to the material, thereby achieving an efficient drying process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0041] See also Figures 1 to 12 In an embodiment of the present invention, an anti-agglomeration lifting and feeding mechanism is connected to a lifting and supporting plate 1, on which a drying kettle 2 is fixed, and includes:

[0042] The conveying pipe 11 is fixedly mounted on the lifting plate 1 and connected to the drying kettle 2, and the side wall of the conveying pipe 11 is connected to a hopper 1101;

[0043] Also includes:

[0044] See also Figure 1-Figure 3A crushing pipe 15 is arranged on the side wall of the conveying pipe 11. A conveying assembly connected to the crushing pipe 15 and the drying kettle 2 is arranged in the conveying pipe 11. The conveying assembly can convey the material to the drying kettle 2 through the crushing pipe 15. The conveying assembly includes a first discharge pipe 13 and a second discharge pipe 14 fixedly installed on the conveying pipe 11. The first discharge pipe 13 is connected to the drying kettle 2, and the second discharge pipe 14 is connected to the crushing pipe 15. A connecting pipe 27 connected to the drying kettle 2 is fixed on the circumferential outer wall of the crushing pipe 15.

[0045] In detail, valves are provided on the first discharge pipe 13 and the second discharge pipe 14, and the switches of the first discharge pipe 13 and the second discharge pipe 14 can be controlled by the valves. When the material needs to be dried, if the humidity of the material is not high, the material will basically remain in a loose state and can be directly transported to the drying kettle 2. At this time, the valve of the first discharge pipe 13 can be opened and the valve of the second discharge pipe 14 can be closed. At the same time, the material to be dried is transported to the conveying pipe 11 through the hopper 1101, and the spiral dragon 12 in the conveying pipe 11 will rotate and lift the material along the length direction of the conveying pipe 11. When the material is lifted to the position coordinated with the first discharge pipe 13, the material can be transported to the drying kettle 2 through the first discharge pipe 13, and the material is dried under the action of the rake drying mechanism.

[0046] Preferably, if the humidity of the material is too high, agglomeration may occur during the material lifting process. When the material agglomerates, the center of the agglomerate may not be dried during the subsequent drying of the material. Therefore, it is necessary to crush the material before drying it. At this time, the valve of the first discharge pipe 13 can be closed and the valve of the second discharge pipe 14 can be opened. Under the action of the spiral dragon 12, the material is lifted to a position that cooperates with the second discharge pipe 14. At this time, the material will be transported to the crushing pipe 15 through the second discharge pipe 14. Under the action of the pump air pushing mechanism and the agglomeration crushing mechanism, the material is crushed. The crushed material can be transported to the drying kettle 2 through the connecting pipe 27 to ensure that the material is fully dried.

[0047] See also Figure 1-Figure 3 , Figure 6-Figure 10, a pump air pushing mechanism is arranged in the crushing tube 15, and the pump air pushing mechanism includes a baffle 20 fixedly installed in the crushing tube 15, and a plurality of air supply pipes 21 equidistantly distributed in a circumference are fixed on the baffle 20. A driving assembly connected to the baffle 20 is arranged in the crushing tube 15, wherein the driving assembly includes a second motor 16 fixedly installed at the end of the crushing tube 15, and a second transmission rod 17 connected to the output shaft of the second motor 16 is rotatably installed in the crushing tube 15, and a first annular groove 1701 is opened on the circumferential outer wall of the second transmission rod 17. A guide structure connected to the second transmission rod 17 is arranged in the crushing tube 15, and the guide structure mentioned above includes a guide column 24 fixedly installed in the crushing tube 15 and fixedly connected to the baffle 20, and a piston disc 22 slidably connected to the second transmission rod 17 is slidably installed on the guide column 24, and a limit block 23 slidably connected to the first annular groove 1701 is fixed on the inner wall of the piston disc 22.

[0048] It should be noted that the partition 20 divides the crushing tube 15 into two independent spaces. The space facing the piston disc 22 is used for pumping gas, and the space facing the second motor 16 is used for crushing agglomerated materials. A one-way valve connected to the air inlet pipe 1501 is installed on the crushing tube 15, and a one-way valve connected to the air supply pipe 21 is installed on the partition 20 to ensure that the space in the crushing tube 15 used for pumping gas can only enter the crushing tube 15 through the air inlet pipe 1501, and can only be discharged to the space for crushing agglomerated materials through the air supply pipe 21. The first annular groove 1701 is composed of two spiral grooves, and the number of spiral turns of each spiral groove is half a turn, and the two spiral grooves are symmetrically arranged. In the initial state, the limit block 23 is located at the end of the stroke of the first annular groove 1701 away from the partition 20, so that the piston plate 22 is located at the end of the stroke in the direction away from the partition 20. When the agglomerated material is transported to the crushing tube 15 through the second discharge pipe 14, the second motor 16 works and drives the second transmission rod 17 to rotate, thereby driving the agglomeration crushing mechanism to move. Under the action of the agglomeration crushing mechanism, the agglomerated material is crushed. At the same time, the second transmission rod 17 also drives the first annular groove 1701 to move and moves at the limit block 23. Under the action of , the piston disc 22 is driven to move, and the piston disc 22 will move along the length direction of the guide column 24. The guide column 24 has a guiding function to ensure that the piston disc 22 moves along the length direction of the second transmission rod 17 and will not rotate with the second transmission rod 17. Under the action of the piston disc 22, the gas in the crushing tube 15 is pushed to the position coordinated with the agglomeration crushing mechanism through the air supply pipe 21. Under the action of air pressure, the crushed material is blown to the position coordinated with the connecting pipe 27, so as to transport the material to the drying kettle 2 through the connecting pipe 27.

[0049] Preferably, when the limit block 23 moves to the end of the stroke on the other side of the first annular groove 1701, the piston disc 22 moves to the end of the stroke in the direction of the partition 20. At this time, the second transmission rod 17 continues to rotate, so that the piston disc 22 moves toward the initial position, and the above steps are repeated to continuously pump air into the crushed material to blow the crushed material to the desired position. Since the crushing tube 15 is placed horizontally, when the material is crushed by the agglomeration crushing mechanism, the material is blown under the action of gas blowing to achieve the effect of conveying the material. The material can also be blown and stirred to a certain extent under the action of air flow stirring to ensure that the crushed material will not agglomerate again due to accumulation.

[0050] See also Figure 3 , Figure 6-Figure 12 The crushing tube 15 is also provided with a clustering crushing mechanism connected with the pump air pushing mechanism, and the pump air pushing mechanism can crush the material in the crushing tube 15 through the clustering crushing mechanism, and blow the crushed material into the drying kettle 2, the clustering crushing mechanism includes a fixed crushing leaf 18 fixedly mounted on the second transmission rod 17, and a plurality of first grooves 1801 distributed at equal intervals are opened on the fixed crushing leaf 18, and a movable crushing leaf 19 cooperating with the fixed crushing leaf 18 is slidably mounted on the second transmission rod 17, and a plurality of second grooves 1901 distributed at equal intervals are opened on the movable crushing leaf 19, and a follow-up translation assembly connected with the movable crushing leaf 19 is provided on the partition 20, wherein the follow-up translation assembly includes a fixed sleeve 25 fixedly mounted on the partition 20, and a second annular groove 2501 is opened on the circumferential outer wall of the fixed sleeve 25, and a limiting column 26 slidably connected with the second annular groove 2501 is fixed on the movable crushing leaf 19.

[0051] Furthermore, there is a small gap between the outer wall of the movable crushing leaf 19 and the fixed crushing leaf 18 and the inner wall of the crushing tube 15, and the second annular groove 2501 is also composed of two spiral grooves, and the number of spiral turns of each spiral groove is also half a turn, and the two spiral grooves are symmetrically arranged; in the initial state, the limit column 26 is located at the end of the stroke of the second annular groove 2501 toward the side of the partition 20, so that the fixed crushing leaf 18 and the movable crushing leaf 19 are in the same vertical plane. At this time, the first groove 1801 and the second groove 1901 are in mutually symmetrical positions. When the material is transported to the crushing tube 15 through the second discharge pipe 14, the material will fall into the first groove 1801 and the second groove 1901. At this time, the second transmission rod 17 rotates and drives the fixed crushing leaf 18 and the movable crushing leaf 19 to rotate, so as to drive the material to move through the first groove 1801 and the second groove 1901. When the material abuts against the inner wall of the crushing tube 15, the material can be crushed. The movable crushing leaves 19 can also drive the second groove 1901 to move, and the first groove 1801 and the second groove 1901 can be staggered with each other. Therefore, under the action of the fixed crushing leaves 18 and the movable crushing leaves 19, the materials in the first groove 1801 and the second groove 1901 are crushed. When the limiting column 26 moves to the end of the stroke on the other side of the second annular groove 2501, the spacing between the movable crushing leaves 19 and the fixed crushing leaves 18 is the largest, and the second transmission rod 17 continues to rotate to control the movable crushing leaves 19 to move toward the initial position through the limiting column 26 and the second annular groove 2501, and repeat the above steps to continuously crush the agglomerated materials.

[0052] Preferably, when the fixed crushing leaf 18 and the movable crushing leaf 19 are installed, the first spacing groove 1802 is opened on the side of the second transmission rod 17 at both ends of the fixed crushing leaf 18, and the second spacing groove 1902 is opened in the middle of the movable crushing leaf 19. Under the action of the first spacing groove 1802 and the second spacing groove 1902, it can be ensured that the movable crushing leaf 19 can slide freely along the length direction of the second transmission rod 17. The first groove 1801 and the second groove 1901 are arranged in a cone shape, and the size of the cone opening is gradually increased along the direction of the rotation center of the second transmission rod 17. Gradually decreases, therefore, the agglomerated materials transported by the second discharge pipe 14 will enter the first groove 1801 and the second groove 1901 when the first groove 1801 and the second groove 1901 are in symmetrical positions, and when the first groove 1801 and the second groove 1901 move alternately, the agglomerated materials can be crushed when cooperating with the inner wall of the crushing tube 15, and the movable crushing leaves 19 can also gradually transport the crushed materials toward the connecting pipe 27 when moving, and with the cooperation of gas blowing, ensure that the crushed materials will not remain in the crushing tube 15.

[0053] See also Figure 1-Figure 5 A disc dryer comprises: a plurality of first heating discs 5 and second heating discs 6 which are equidistantly and staggeredly distributed, the first heating discs 5 and the second heating discs 6 are fixedly connected to the drying kettle 2, a rake-dried drying mechanism cooperating with the first heating discs 5 and the second heating discs 6 is arranged in the drying kettle 2, the rake-dried drying mechanism comprises a first motor 3 fixedly mounted on the bottom of the drying kettle 2, a first transmission rod 4 connected to the output shaft of the first motor 3 is rotatably mounted in the drying kettle 2, a driven assembly is arranged on the first transmission rod 4, wherein the driven assembly comprises a plurality of first supporting sleeves 7 and a second supporting sleeve 9 which are fixedly mounted on the first transmission rod 4 and equidistantly and staggeredly distributed, a plurality of first rake blades 8 which are equidistantly distributed circumferentially are fixed on the first supporting sleeve 7, and a plurality of second rake blades 10 which are equidistantly distributed circumferentially are fixed on the second supporting sleeve 9.

[0054] Furthermore, a discharge pipe is provided inside the drying kettle 2 for discharging the dried material, and the first heating plate 5 and the second heating plate 6 are staggeredly distributed along the length direction of the drying kettle 2, the size of the first heating plate 5 is smaller than that of the second heating plate 6, the first heating plate 5 is rotatably connected to the first transmission rod 4, the center of the second heating plate 6 is open, and a certain gap is left between the first transmission rod 4, the first heating plate 5 and the second heating plate 6 are hollow inside for passing a heating medium, the first rake blade 8 and the second rake blade 10 are inclined, and the inclination angles of the first rake blade 8 and the second rake blade 10 are opposite, the first rake blade 8 is in contact with the surface of the second heating plate 6, and the second rake blade 10 is in contact with the surface of the first heating plate 5, when the material is transported to the drying kettle 2 through the first discharge pipe 13 or the connecting pipe 27, the material will first fall onto the topmost first heating plate 5, and then Under the action of the hot plate 5, the material thereon is dried. At the same time, the first motor 3 works and drives the first transmission rod 4 to rotate, thereby driving the first supporting sleeve 7 and the second supporting sleeve 9 to move. The first supporting sleeve 7 and the second supporting sleeve 9 will drive the first rake 8 and the second rake 10 to move. Under the action of the second rake 10, the material placed on the top first heating plate 5 is gradually transported toward the outer direction of the first heating plate 5 until the material is separated from the first heating plate 5 and falls onto the second heating plate 6 below. At the same time, under the action of the first rake 8, the material on the second heating plate 6 is controlled to move toward the center direction of the second heating plate 6 until the material on the second heating plate 6 is discharged from the central gap of the second heating plate 6 and falls into the first heating plate 5 of the next layer. The above steps are repeated until the material is separated from the first heating plate 5 and the second heating plate 6 and falls into the bottom of the drying kettle 2.

[0055] Preferably, when the wet material is continuously added to the first layer of the first heating plate 5 of the drying kettle 2 through the first discharge pipe 13 or the connecting pipe 27, the rake arm with the second rake blade 10 performs a rotary motion inside the drying kettle 2, so that the second rake blade 10 continuously turns the material. This turning action not only helps to evenly distribute the material on the first heating plate 5 and the second heating plate 6, but also promotes the heat exchange between the material and the heating medium, thereby improving the drying efficiency. The flow of the material on the first heating plate 5 and the second heating plate 6 follows the trajectory of the exponential spiral line. When on the first heating plate 5, the material is gradually moved to the outer edge and falls to the outer edge of the second heating plate 6 below at the outer edge. When on the second heating plate 6, the material moves inward and falls into the first heating plate 5 of the next layer from the middle drop port. This design of alternating the first heating plate 5 and the second heating plate 6 up and down allows the material to flow continuously through the entire drying kettle 2, thereby achieving the purpose of continuous drying.

[0056] The heating medium in the first heating plate 5 and the second heating plate 6 can be saturated steam, hot water, thermal oil, etc. The heating medium enters from one end of the first heating plate 5 and the second heating plate 6, and is discharged from the other end after heat exchange in the plate. This design enables the first heating plate 5 and the second heating plate 6 to quickly transfer heat to the material, thereby achieving an efficient drying process.
