Description

Technical Field

[0001] The present invention relates to the technical field of drum drying, and in particular to drum drying equipment. Background Art

[0002] At present, in drum drying equipment, the drum is usually equipped with a lifting plate inside to turn and mix the materials to ensure that the materials can be evenly heated, thereby improving the drying efficiency. The lifting plates inside are mostly fixedly installed. This static design results in the lifting plates only being able to simply push and turn the materials when the drum rotates, and cannot effectively turn and break up the materials. At the same time, the materials are easily stuck between the lifting plates and the inner wall of the drum.

[0003] A search revealed a Chinese utility model with authorization publication number CN221802318U, which discloses an alumina drum drying device. This patent extends the residence time of the alumina in the air by gradually widening the shoveling plate, thereby improving the contact efficiency with the hot air and thus enhancing the drying efficiency. However, the patent's design of gradually widening the shoveling plate still has a relatively simple effect, and the fixed installation setting still cannot solve the problem of material sticking at the connection between the shoveling plate and the inner wall of the drum. At the same time, it is not effective in turning over and breaking up the material. Summary of the Invention

[0047] By adopting the above technical solution, the present invention has the following beneficial effects:

[0048] 1. Through the arrangement of the cover plate and the processing chamber and other structures, when it is necessary to clean, repair or adjust several adjustable parts of the drum body in the processing chamber, the operation can be achieved by opening the cover plate, which improves the convenience of use.

[0049] 2. Through the arrangement of the reciprocating assembly and the scraper body, during the operation of the drum body, the reciprocating assembly is started by its own rotation, and after the reciprocating assembly is started, the reciprocating screw is driven to rotate. The reciprocating screw realizes the horizontal reciprocating motion of the scraper body inside the drum body, thereby improving the ability to turn over and break up the materials and improving the drying effect. At the same time, due to the movement of the scraper body, the materials sticking to the connection between the scraper body and the inner wall of the drum body can be scraped off, achieving the effect of internal cleaning and high material utilization.

[0050] 3. Through the setting of the extension plate and heating groove and other structures, each copy board body is provided with an individually controllable extension plate. The length of the copy board body can be adjusted by controlling the extension plate according to the actual use needs and the different characteristics of the materials, which makes it more flexible to use. At the same time, through the setting of the heating groove, the hot air in the heating cavity can be directly extended to the copy board body through the heating groove, which improves the heat transfer effect and accelerates the efficiency of material drying.

[0051] 4. Through the arrangement of the annular sleeve and the connecting port and other structures, the connecting port connects the inner and outer spaces of the drum body. The annular sleeve as the intermediate connecting component avoids the problem of leakage of materials in the drum body caused by the spatial communication on the basis of realizing the spatial communication, and a second air outlet is opened on the annular sleeve. The second air outlet faces the inner wall of the drum body. While realizing the direct contact of the material inside the drum body with hot air for drying, the material stuck on the inner wall can also be blown off.

[0052] 5. Through the setting of structures such as the air outlet sleeve and the inclination angle, the air outlet sleeve is horizontally arranged in the drum body. Part of the hot air is discharged through the air outlet two, and the rest is discharged through the air outlet three on the air outlet sleeve. The air outlet three can blow the hot air from the discharge end to the feed end along the direction of the air outlet sleeve, which is opposite to the setting of the hot air in the heating chamber blowing from the feed end to the discharge end, achieving a more uniform heating and drying effect. The setting of the inclination angle can allow the hot air discharged from the air outlet three to be discharged downward and then diffuse outward in a fan-shaped manner, further improving the drying effect.

[0053] 6. Through the setting of structures such as the auger and the distribution plate, the rotating auger can further crush the material while conveying it, so that the contact area between the material and the hot air is increased, and the drying effect is improved. The discharge trough 1 and the discharge trough 2 on the distribution plate can quantitatively feed the material conveyed by the auger into the interior of the drum body in batches, avoiding the accumulation of materials and further improving the drying effect.

[0079] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0080] Example 1

[0081] like Figure 1-8 As shown, the drum drying equipment includes:

[0082] The device body 1 includes a base plate 11 and a processing chamber 12 connected to the base plate 11, a feed cover 16 and a discharge cover 17. The processing chamber 12 is connected to an air inlet pipe 14;

[0083] A drum body 2 rotatably connected to the processing chamber 12;

[0084] a driving assembly 3 connected to the drum body 2 to drive the drum body 2 to rotate;

[0085] The drum body 2 is divided into a discharge end 102 and a feed end 101. The feed end 101 is located in the processing chamber 12 near the air inlet pipe 14. The discharge end 102 partially extends to the outside of the processing chamber 12 and extends into the discharge cover 17. The discharge cover 17 is provided with a discharge port 18.

[0086] The apparatus body 1 further includes a cover plate 13 hinged at one end to the processing chamber 12. The cover plate 13 is adapted to be rotated to control the opening and closing of the space at the top of the processing chamber 12. The cover plate 13 closes the processing chamber 12 and is adapted to form a heating chamber 21 between the drum and the cover plate 13. An air outlet pipe 15 is connected to the cover plate 13 and is located near the discharge end 102.

[0087] The feed cover 16 is provided with a feed assembly 4, which includes a delivery pipe 41 and a feed pipe 42. The delivery pipe 41 is fixed in the feed cover 16 and extends into the drum body 2. The feed pipe 42 is connected to the delivery pipe 41.

[0088] A plurality of copy board bodies 6 are slidably arranged on the drum body 2. The drum body 2 is provided with a plurality of sliding grooves corresponding to the copy board bodies 6. The copy board bodies 6 are located in the sliding grooves.

[0089] A reciprocating assembly 5 is connected to the copy board body 6 to drive the copy board body 6 to move horizontally back and forth.

[0090] like Figure 5 As shown, the driving assembly 3 includes a servo motor 31, a driving gear 32 and a driven gear 33;

[0091] A servo motor 31 is mounted on one side of the discharge cover 17. The output shaft of the servo motor 31 is rotatably disposed within the discharge cover 17. A driving gear 32 is located between the discharge cover 17 and the processing chamber 12 and is connected to the output shaft. A driven gear 33 is fixedly sleeved on the outer circumferential surface of the portion of the drum body 2 extending out of the processing chamber 12. The driven gear 33 is engaged with the driving gear 32.

[0092] like Figure 6-9 As shown, the reciprocating assembly 5 includes a reciprocating screw 51 and an internal gear sleeve 53;

[0093] The reciprocating screw rod 51 is rotatably installed in the drum body 2, the reciprocating screw rod 51 passes through the corresponding sliding groove, and the corresponding copy board body 6 is assembled on the outside of the reciprocating screw rod 51;

[0094] The inner gear sleeve 53 is fixedly connected to the side wall of the processing chamber 12 near the feed end 101. One end of the reciprocating screw 51 is connected to the outer gear 52, and the outer gear 52 is meshed with the inner gear sleeve 53.

[0095] Two symmetrically arranged moving grooves 62 are provided in the sliding groove, and the corresponding two sides of the copying plate body 6 are connected with moving plates 61. The reciprocating screw rod 51 is suitable for being driven to rotate to drive the copying plate body 6 to move in the sliding groove, and then drive the moving plate 61 to move in the moving groove 62.

[0096] like Figure 10As shown, the copy board body 6 includes an extension plate 63, a threaded rod 66 and a support rod 64 which are slidably connected in the copy board body 6;

[0097] The threaded rod 66 is divided into a smooth portion and a threaded portion. The smooth portion is rotatably mounted in the main body 6 of the copy board. The threaded portion passes through the interior of the extension plate 63. The extension plate 63 is threadedly sleeved on the exterior of the threaded portion. The threaded rod 66 is adapted to be rotated to drive the extension plate 63 to extend and retract in the main body 6 of the copy board.

[0098] A support rod 64 is fixedly connected to the inside of the copy board body 6 , and the extension plate 63 is slidably connected to the outside of the support rod 64 .

[0099] like Figure 10 As shown, a heating groove 65 which does not penetrate the main body 6 of the copy board is opened in the main body 6 , and the opening of the heating groove 65 is communicated with the heating chamber 21 .

[0100] The working principle of this embodiment is as follows:

[0101] When the device needs to start working, the cover 13 is first closed to seal the processing chamber 12 to form a closed space, and a heating chamber 21 is formed between the closed space and the drum body 2;

[0102] Then, the driving assembly 3 is started, and the driving gear 1 32 is controlled to rotate by the servo motor 1 31. The driving gear 1 32 and the driven gear 2 86 are meshed, so that the drum body 2 starts to rotate. At the same time, hot air is introduced through the air inlet pipe 14. The hot air flows in the heating chamber 21, and heats the outer surface of the drum by heat transfer, thereby heating and drying the material inside the drum body 2. The air inlet pipe 14 and the exhaust pipe are respectively arranged at the feeding end 101 and the discharging end 102 of the drum body 2 to ensure that the hot air can effectively heat the entire drum body 2.

[0103] Finally, the hot gas is discharged through the outlet pipe 15. The outlet pipe 15 can be connected to an external circulation device or waste heat recovery device to reuse the discharged hot gas.

[0104] After the above preparations are completed, the material to be dried is fed into the conveying pipe 41 through the feed pipe 42, and the material is fed into the interior of the drum body 2 through the conveying pipe 41. The drum body 2 rotates to drive the material inside to roll, and cooperates with the lifting plate body 6 to turn the material, thereby increasing the contact area between the material and the heat;

[0105] During the rotation of the drum body 2, the outer gear 52 in the reciprocating assembly 5 revolves around the drum body 2 as the center of the circle. During the revolution, the outer gear 52 engages with the inner gear sleeve 53 fixedly connected to the processing chamber 12, so that the outer gear 52 rotates on the basis of the revolution, thereby driving the reciprocating screw 51 to rotate. The rotation of the reciprocating screw 51 drives the external assembly of the lifting plate body 6 to reciprocate in the horizontal direction. During the reciprocating motion of the lifting plate body 6, the moving plate 61 moves in the moving groove 62, ensuring that the lifting plate body 6 can ensure the sealing of the drum body 2 during the movement, avoiding In case of material leakage, the reciprocating lifting plate body 6 can turn the material more effectively, making it more evenly exposed to the hot air, thereby improving the drying efficiency, helping to break up the agglomeration of the material, and improving the mixing uniformity of the material. The dynamic lifting plate movement reduces the possibility of the material sticking to the inner wall of the drum, reduces the risk of agglomeration or aggregation, and keeps the inner wall of the drum clean. At the same time, the lifting plate body 6 can move the sticky material in the contact part between the lifting plate body 6 and the inner wall of the drum body 2 through the movement of the moving plate 61, forming a friction between the inner wall of the drum body 2, and scraping off the sticky material;

[0106] It should be noted that the thread grooves on the reciprocating screw 51 do not cover the entire reciprocating screw 51. The distribution and length of the thread grooves on the reciprocating screw 51 are only required to achieve the stroke of the movable plate 61 on the corresponding copying plate body 6 moving in the movable groove 62. The connection between the reciprocating screw 51 and the copying plate body 6 can be a ball nut. This part is existing technology and will not be described in detail here.

[0107] At the same time, the copy board body 6 also has the function of adjusting the length separately. According to the actual production needs and the characteristics of different materials, before the drying equipment is started, the cover 13 is opened and each copy board body 6 is adjusted manually. When adjusting, the threaded rod 66 is rotated by a tool. The tool can be a wrench or the like. When the threaded rod 66 is rotated, the extension plate 63 restricted in the interior of the copy board body 6 will move along the axial direction of the threaded rod 66. The extension plate 63 is retracted by the forward and reverse rotation of the threaded rod 66. The extension plate 63 will not completely extend out of the interior of the copy board body 6. The two always keep in contact. It can be controlled by the number of turns manually or by setting a limit assembly. The limit assembly is shown in the figure. The function of the support rod 64 is to further prevent the extension plate 63 from rotating under the drive of the threaded rod 66, play a guiding effect, and at the same time support the extended extension plate 63 to prevent the extended extension plate 63 from being bent by the material after being extended.

[0108] After adjusting the length of each copy board body 6 in the above manner, the overall length can be unified, or the lengths can be different and stepped. The specific adjustment result is selected according to actual needs.

[0109] In order to improve the heat transfer effect of the drum body 2 to the material inside it, a heating groove 65 is opened on the scraper body 6. In addition to acting on the outer peripheral surface of the drum body 2, hot air also covers the heating groove 65. The heating groove 65 directly transfers heat to the scraper body 6, thereby causing the scraper body 6 to heat up. After the heating, the scraper body 6 comes into contact with the material, further accelerating the efficiency of material drying.

[0110] Example 2

[0111] like Figure 11-14 As shown, this embodiment further includes the following structures on the basis of the first embodiment: an internal heating assembly 7 is provided inside the drum body 2 near the discharge end 102, and the internal heating assembly 7 includes a connection port 78 opened on the inner wall of the drum body 2, a sealing sleeve 72 and an annular sleeve 71;

[0112] The connection port 78 is adapted to connect the inner cavity of the drum body 2 with the heating chamber 21;

[0113] The sealing sleeve 72 is fixedly connected to the inner wall of the drum body 2, and the annular sleeve 71 is rotatably installed in the sealing sleeve 72, and a sealing arrangement is provided between the sealing sleeve 72 and the annular sleeve 71;

[0114] An air storage tank is provided in the annular sleeve 71 and is communicated with the connecting port 78;

[0115] A plurality of second gas outlets 701 are provided on one side of the annular sleeve 71 near the feed end 101, and the second gas outlets 701 are communicated with the gas storage tank;

[0116] A switch plate 79 is detachably connected to the outer circumference of the drum body 2 , and the switch plate 79 is adapted to cover the connection port 78 to control the opening and closing of the connection port 78 ;

[0117] An air outlet 19 is provided in the discharge cover 17 .

[0118] like Figure 13 As shown, the internal heating assembly 7 further includes at least one internal air inlet 74 opened in the air storage tank, a connecting plate 73 corresponding to the internal air inlet 74, and an air outlet sleeve 75;

[0119] One end of the connecting plate 73 is connected to the air outlet sleeve 75, and the other end of the connecting plate 73 is connected to the annular sleeve 71;

[0120] The air outlet sleeve 75 is provided with an air outlet port 3 76 , the outlet of the air outlet port 3 76 is downward;

[0121] The inner cavity of the connecting plate 73 is communicated with the air outlet 3 76 and the inner air inlet 74 respectively;

[0122] The other end of the gas outlet sleeve 75 is connected to the inner wall of the processing chamber 12 near the feed end 101.

[0123] like Figure 15 As shown, an inclination angle 77 is provided at the outlet of the third air outlet 76 .

[0124] The working principle of this embodiment is as follows:

[0125] When the drying equipment is operating normally, air is only taken in through the air inlet pipe 14 and exhausted through the air outlet pipe 15. The hot air flows in the heating chamber 21, transfers heat to the drum body 2, and thus achieves drying of the material. This method is indirect contact. The main difference between indirect contact and direct contact is that it does not contaminate the material, but the drying efficiency is lower than direct contact. However, different processing methods should be selected for different types of materials. When facing materials that can directly contact with hot air, the connection port 78 can be opened by removing the switch plate 79. The connection port 78 connects the internal space of the drum body 2 with the heating chamber 21, thereby achieving the effect of indirect contact and direct contact with the material at the same time.

[0126] The specific process is that after the connection port 78 is opened, the hot air in the heating chamber 21 flows into the air storage tank in the annular sleeve 71 through the connection port 78, and is then discharged through the second air outlet 701. The opening of the second air outlet 701 faces the feed end 101, thereby achieving the effect of blowing the hot air from the discharge end 102 to the feed end 101, which is opposite to the flow direction of the hot air in the heating chamber 21, thereby achieving uniform heating of the material. At the same time, the position of the second air outlet 701 is close to the inner wall of the drum body 2. When blowing, the material sticking to the inner wall of the drum body 2 can be processed to a certain extent and the sticky material can be blown off;

[0127] On this basis, an air outlet sleeve 75 is also provided, which is connected to the annular sleeve 71 through a connecting plate 73. An internal air inlet 74 is provided in the air storage tank in the annular sleeve 71. The function of the internal air inlet 74 is to guide part of the hot air entering the air storage tank into the connecting plate 73, and then the hot air is transported to the air outlet sleeve 75 by the connecting plate 73. An air outlet three 76 is provided in the air outlet sleeve 75, and the air outlet three 76 discharges the hot air downward. The air outlet sleeve 75 is a long strip as a whole and is horizontally arranged inside the drum body 2, and one end is connected to the inner wall of the processing chamber 12 near the feed end 101. The hot air discharged from the air outlet three 76 is also blown in the direction of the discharge end 102 toward the feed end 101, which is opposite to the flow direction of the hot air in the heating chamber 21, further improving the effect of uniform heating of the material;

[0128] It should be noted that the annular sleeve 71 is connected to the inner wall of the drum body 2 through the sealing sleeve 72. The sealing sleeve 72 rotates with the rotation of the drum body 2, and the annular sleeve 71 is rotatably installed in the sealing sleeve 72. Therefore, when the drum rotates, the annular sleeve 71 does not rotate. In addition, because the annular sleeve 71 is connected to the air outlet sleeve 75, and the air outlet sleeve 75 is connected to the inner wall of the processing chamber 12, the entire internal heating assembly 7 is stably connected to the inside of the drum body 2 and is not affected by the rotation of the drum body 2. At the same time, because the connecting port 78 is always in communication with the air storage tank in the annular sleeve 71, no matter how the drum body 2 rotates, it can be ensured that part of the hot gas in the heating chamber 21 will flow into the interior of the annular sleeve 71.

[0129] The hot air in the air outlet sleeve 75 is always blown downward at the air outlet 76 to prevent the constantly turning materials from accidentally entering the interior of the air outlet 76. At the same time, the principle of hot air rising is utilized to quickly distribute the hot air. In addition, an inclined angle 77 is provided at the outlet of the air outlet 76 to guide the discharged hot air. Driven by the inclined angle 77, the hot air blown downward is diffused in a fan-shaped manner, which accelerates the diffusion of the hot air and can better contact the turning materials, thereby improving the drying efficiency.

[0130] The hot air in the drum body 2 eventually flows out through the air outlet 19 in the discharge cover 17. The air outlet 19 can also be connected to an external circulation device or heat recovery device.

[0132] like Figure 16 As shown, this embodiment further includes the following structures on the basis of the first embodiment: a material distribution component 8 is provided in the conveying pipe 41, and the material distribution component 8 includes a second servo motor 81, a first rotating shaft 83 and a second rotating shaft 85;

[0133] The first rotating shaft 83 and the second rotating shaft 85 are both rotatably mounted inside the delivery pipe 41, and the first rotating shaft 83 is located above the second rotating shaft 85;

[0134] The second servo motor 81 is installed outside the delivery tube 41 and is connected to the first rotating shaft 83 to drive the first rotating shaft 83 to rotate in the delivery tube 41;

[0135] A auger 82 is fixedly mounted on the outer surface of the rotating shaft 83;

[0136] The outer fixed sleeve of the rotating shaft 1 83 is provided with a driving gear 2 84 , and the outer fixed sleeve of the rotating shaft 2 85 is provided with a driven gear 2 86 , and the driven gear 2 86 is meshed with the driving gear 2 84 ;

[0137] A material distribution plate 87 is fixedly sleeved on the outer circumference of the second rotating shaft 85;

[0138] A material discharge trough 1 88 and a material discharge trough 2 89 are respectively provided on the material distribution tray 87 , and the material discharge trough 1 88 and the material discharge trough 2 89 are located in opposite positions on the material distribution tray 87 .

[0139] like Figure 1-2 As shown, an angle adjustment assembly 9 is provided at the bottom of the device body 1, and the angle adjustment assembly 9 includes a fixing plate 91 and a hinge component 92;

[0140] One end of the fixed plate 91 is connected to the end of the bottom of the bottom plate 11 near the discharge cover 17 through a hinge component 92;

[0141] A height adjustment component 93 is provided on the other end of the fixing plate 91 and on the end of the bottom of the bottom plate 11 close to the feed cover 16 .

[0142] The working principle of this embodiment is as follows:

[0143] When adding materials to the feed pipe 42, the servo motor 2 81 is started to drive the rotating shaft 1 83 to rotate. When the rotating shaft 1 83 rotates, the auger 82 is driven to rotate. The material enters the interior of the conveying pipe 41 through the feed pipe 42. Inside the conveying pipe 41, it is further crushed by the auger 82 and is stably fed into the interior of the drum body 2. After further crushing, the contact area with the hot air is increased, thereby improving the drying efficiency. The stable conveying of the auger 82 can avoid the problem of blockage during the feeding process.

[0144] The conveying pipe 41 is long, and conveying only through the auger 82 will cause the material to be discharged from the bottom of the conveying pipe 41 just after entering the interior of the drum body 2, thereby causing the material to accumulate at the feed end 101 of the drum body 2, which is not conducive to the entire drying process;

[0145] Therefore, a distribution plate 87 is also provided at the bottom of the auger 82, and the distribution plate 87 realizes synchronous rotation with the auger 82 through the engagement of the driving gear 2 84 and the driven gear 2 86. When the auger 82 is conveying materials, the distribution plate 87 rotates continuously, and the discharge chute 1 88 and the discharge chute 2 89 on the distribution plate 87 work alternately through the reverse setting. For example, when the auger 82 is conveying materials, the discharge chute 2 89 on the distribution plate 87 puts the materials into the interior of the drum body 2. When the discharge chute 2 89 is also rotated into the conveying pipe 41, the conveying pipe 41 at the feed end 101 is blocked by the distribution plate 87 and cannot discharge materials. At this time, the materials continue to move with the rotation of the auger 82, and the movement At the discharge trough 88, the discharge trough 88 and the discharge trough 2 89 are set in the opposite direction. When the discharge trough 2 89 has not rotated into the conveying pipe 41, the discharge trough 88 is located in the conveying pipe 41. At this time, the discharge trough 88 can receive the material and then rotate to put the material into the interior of the drum body 2. In summary, the material distribution plate 87 rotates continuously, and the discharge trough 1 88 and the discharge trough 2 89 work alternately to realize that part of the material transported by the auger 82 is put into the feed end 101 of the drum body 2, and part is put into the discharge end 102. The material is put in batches and quantitatively, and the material is spread all over the interior of the drum body 2, further dispersing the material to avoid accumulation and agglomeration, thereby improving the drying efficiency.

[0146] After the drying process is completed, the angle adjustment assembly 9 is used to raise the feed cover 16. After the raising, the entire equipment is tilted, and the material in the drum body 2 slides along the tilt direction into the discharge cover 17 and is finally discharged through the discharge port 18.

[0147] The angle adjustment assembly 9 includes a fixed plate 91 located at the bottom, and the fixed plate 91 is connected to the bottom of the base plate 11 at one end of the discharge cover 17 through a hinged component 92. The hinged component 92 can be a hinged plate connected to the fixed plate 91 and a hinge shaft rotatably installed on the hinged plate. The hinge shaft is connected to the bottom of the base plate 11. A height adjustment component 93 is provided between the fixed plate 91 and the bottom of the base plate 11 at one end of the feed cover 16. The height adjustment component 93 can be a bolt. By rotating the bolt, the feed cover 16 is raised, thereby realizing the tilting of the equipment angle and discharging the material through the discharge port 18 on the discharge cover 17.

It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
