Description

Technical Field

[0001] This utility model belongs to the technical field of disc dryers, and in particular relates to a disc dryer that prevents hard materials from abrading the filler. Background Technology

[0002] A disc dryer is an industrial drying equipment that uses a rotating disc as a heating element to dry materials through heat conduction. It has the advantages of high drying efficiency, low energy consumption, simple operation, and the ability to effectively process a variety of materials.

[0003] For example, Chinese patent CN215113723U discloses a disc dryer, including a housing, a rotating shaft, a disc assembly, and a drive assembly. The disc assembly passes through the rotating shaft, and multiple rake arms are arranged on the discs. An air inlet pipe and a water outlet pipe are respectively arranged inside the housing. The air inlet pipe includes a main air inlet pipe and multiple branch air inlet pipes. The main air inlet pipe connects to each of the branch air inlet pipes, and each branch air inlet pipe corresponds to and communicates with one of the discs. The water outlet pipe communicates with each of the discs. The water outlet pipe includes a main water outlet pipe and multiple branch water outlet pipes. The main water outlet pipe connects to each of the branch water outlet pipes, and each water outlet pipe corresponds to and communicates with one of the discs. A first sensor is arranged inside the housing corresponding to the air inlet pipe, and a second sensor is arranged inside the housing corresponding to the water outlet pipe. This utility model provides a disc dryer for real-time monitoring of condensate water accumulation and other functions generated inside the discs.

[0004] The aforementioned patent has the following problems:

[0005] This patented device has several drawbacks in use, such as: the feeding speed cannot be controlled; excessively fast feeding can lead to material accumulation, while excessively slow feeding will affect the drying efficiency of the disc dryer; furthermore, larger materials can easily cause wear and tear on the disc dryer, thus affecting its service life; and the discharge direction cannot be adjusted arbitrarily, making it unsuitable for different site conditions. Therefore, we propose a disc dryer with a design that prevents wear from hard materials on the packing material. Utility Model Content

[0006] The purpose of this invention is to provide a disc dryer that prevents hard materials from abrading the filler, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a disc dryer for preventing wear of fillers by hard materials, comprising a disc dryer, and further comprising:

[0008] The feed hopper is fixedly installed at the feed inlet of the disc dryer. A rectangular groove is opened in the feed hopper, and blocking blocks are symmetrically slidably installed in the rectangular groove. Sealing gaskets are fixedly installed on the opposite side of the two blocking blocks.

[0009] A drive assembly located inside the feed hopper, used to drive two blocking blocks closer to or further apart from each other;

[0010] Two baffles are symmetrically fixedly installed inside the feed hopper and located below the rectangular groove. Two crushing rollers are rotatably installed inside the feed hopper and at the bottom of the baffles. A second motor is fixedly installed on one side of the feed hopper. The output end of the second motor passes through one side of the feed hopper and is coaxially connected to one of the crushing rollers. Two gears are rotatably installed on the other side of the feed hopper. One end of each gear passes through the other side of the feed hopper and is coaxially connected to the two crushing rollers respectively. A discharge pipe is rotatably installed at the discharge port of the disc dryer.

[0011] A limiting component is located inside the discharge pipe and is used to limit the discharge pipe.

[0012] In this technical solution, during use, the operator can first start the second motor. The output shaft of the second motor will drive one of the crushing rollers to rotate. The rotation of one crushing roller will drive one of the gears to rotate. Under the meshing action, the rotation of one gear will drive another gear to rotate, and the rotation of the other gear will drive another crushing roller to rotate. Subsequently, the operator can adjust the distance between the two blocking blocks by driving the two blocking blocks away from each other through the drive component according to the size of the material. Thus, the feeding speed of the material can be controlled at will according to the size of the material, ensuring that the material is not fed too fast or too slow.

[0013] Subsequently, the personnel can put the material to be dried into the feed hopper. Under the action of two blocking blocks and two baffles, the material will fall between the two crushing rollers. The rotation of the two crushing rollers can crush larger materials, preventing larger materials from causing wear on the disc dryer, thereby extending the service life of the disc dryer.

[0014] After the material inside the disc dryer is dried, it will be discharged to the outside through the discharge pipe. When it is necessary to adjust the discharge direction of the discharge pipe, the personnel can release the limit component to the discharge pipe and rotate the discharge pipe to adjust the discharge direction. When the discharge pipe is rotated to a suitable angle, the limit component can limit the discharge pipe to ensure that the discharge direction can be adjusted. The discharge pipe direction can be flexibly adjusted according to the layout of the production workshop and the position of subsequent equipment, which can better adapt to different site conditions, make the connection between the disc dryer and other equipment more reasonable, save space, and improve the space utilization rate of the workshop.

[0015] In the above technical solution, the driving component further includes:

[0016] A sliding groove is formed on one side of a rectangular groove. Two sliding blocks are slidably installed in the sliding groove. One end of each sliding block passes through the sliding groove and is fixed to two blocking blocks respectively. A bidirectional threaded rod is rotatably installed in the sliding groove. One end of the bidirectional threaded rod passes through the two sliding blocks. An installation groove is formed in the feed hopper on one side of the sliding groove. A first motor is fixedly installed in the installation groove. One end of the first motor passes through one side of the installation groove and is coaxially connected to the bidirectional threaded rod.

[0017] In this technical solution, starting the first motor causes the output shaft of the first motor to drive the bidirectional threaded rod to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod causes the two sliding blocks to move away from each other. The two sliding blocks moving away from each other causes the two blocking blocks to move away from each other. By adjusting the distance between the two blocking blocks, the feeding speed of the material can be controlled at will according to the size of the material, ensuring that the material is not fed too fast or too slow.

[0018] In the above technical solution, one end of the sliding block is tightly welded to the blocking block, the bidirectional threaded rod is threadedly connected to the sliding block, the output shaft of the first motor is rotatably connected to the feed hopper, and the bidirectional threaded rod is provided with two sections of threads with opposite directions of rotation.

[0019] In this technical solution, it is ensured that the movement of the sliding block can drive the blocking block to move, that the rotation of the bidirectional threaded rod can drive the two sliding blocks to move away from or towards each other, and that the output shaft of the first motor can rotate normally in the feed hopper.

[0020] In the above technical solution, the limiting component further includes:

[0021] The groove is formed inside the discharge pipe. A limiting rod is slidably installed inside the groove. Several limiting holes are formed at the bottom of the disc dryer and on the periphery of the discharge pipe. The top end of the limiting rod passes through the top of the groove and extends into one of the limiting holes. A spring fixed to the bottom of the groove is fixed at the bottom end of the limiting rod. One side of the limiting rod passes through the groove and extends to the outside.

[0022] In this technical solution, when it is necessary to adjust the discharge direction of the discharge pipe, the operator can move the limiting rod downwards. The downward movement of the limiting rod will compress the spring, causing it to contract until the top of the limiting rod moves out of the disc dryer. At this point, the limiting rod can release the limiting rod from the discharge pipe, allowing the operator to rotate the discharge pipe to adjust its discharge direction. When the discharge pipe is rotated to the appropriate angle, the limiting rod is released. Under the spring's rebound force, the spring will compress the limiting rod upwards until the top of the limiting rod inserts into the corresponding limiting hole. At this point, the limiting rod can limit the discharge pipe, ensuring that the discharge direction can be adjusted. The discharge pipe direction can be flexibly adjusted according to the layout of the production workshop and the location of subsequent equipment, better adapting to different site conditions. This makes the connection between the disc dryer and other equipment more reasonable, saves space, and improves the space utilization rate of the workshop.

[0023] In the above technical solution, the top end of the limiting rod is inserted into the limiting hole, and the plurality of limiting holes are distributed in a ring at equal intervals.

[0024] In this technical solution, it is ensured that the top of the limiting rod can be inserted into the limiting hole, and the distribution of several limiting holes is guaranteed to be uniform.

[0025] In the above technical solution, the two gears mesh with each other, and the output shaft of the second motor is rotatably connected to the feed hopper.

[0026] In this technical solution, it is ensured that the rotation of one gear can drive the rotation of the other gear, and that the output shaft of the second motor can rotate normally inside the feed hopper.

[0027] In the above technical solution, one side of the blocking block is inclined, and the top surface of the baffle is inclined.

[0028] In this technical solution, it is ensured that the material falls between the two crushing rollers under the blocking action of the two blocking blocks and the two baffles.

[0029] The beneficial effects of this utility model are:

[0030] 1. This disc dryer with anti-wear packing material for hard materials, through the setting of a second motor, and the cooperation of the second motor, crushing roller, gear, blocking block, drive assembly and baffle, can arbitrarily control the feeding speed of the material according to the size of the material, ensuring that the material is fed too fast or too slow, and can also crush larger materials to prevent larger materials from causing wear to the disc dryer.

[0031] 2. This disc dryer with anti-wear packing material for hard materials, through the setting of the discharge pipe, and with the cooperation of the discharge pipe and the limiting component, ensures that the discharge direction of the discharge pipe can be adjusted. The discharge pipe direction can be flexibly adjusted according to the layout of the production workshop and the position of subsequent equipment, which can better adapt to different site conditions, make the connection between the disc dryer and other equipment more reasonable, save space, and improve the space utilization rate of the workshop.

[0047] Example 1:

[0048] Please see Figure 1 - Figure 8 As shown, this embodiment provides a disc dryer for preventing hard materials from abrading the filler, including a disc dryer 1, and further comprising:

[0049] Feed hopper 2 is fixedly installed at the feed inlet of disc dryer 1. A rectangular groove 3 is provided inside the feed hopper 2. A blocking block 4 is symmetrically slidably installed inside the rectangular groove 3. A sealing gasket 5 is fixedly installed on the opposite side of the two blocking blocks 4.

[0050] The drive assembly is located inside the feed hopper 2 and is used to drive the two blocking blocks 4 to move closer to or further away from each other;

[0051] Two baffles 12 are symmetrically fixedly installed inside the feed hopper 2 and below the rectangular trough 3. Two crushing rollers 11 are rotatably installed inside the feed hopper 2 and at the bottom of the baffles 12. A second motor 13 is fixedly installed on one side of the feed hopper 2. The output end of the second motor 13 passes through one side of the feed hopper 2 and is coaxially connected to one of the crushing rollers 11. Two gears 14 are rotatably installed on the other side of the feed hopper 2. One end of each gear 14 passes through the other side of the feed hopper 2 and is coaxially connected to the two crushing rollers 11 respectively. A discharge pipe 15 is rotatably installed at the discharge port of the disc dryer 1.

[0052] A limiting component is located inside the discharge pipe 15 and is used to limit the discharge pipe 15.

[0053] In operation, the operator can first start the second motor 13. The output shaft of the second motor 13 will drive one of the crushing rollers 11 to rotate. The rotation of one crushing roller 11 will drive one of the gears 14 to rotate. Under the meshing action, the rotation of one gear 14 will drive the other gear 14 to rotate. The rotation of the other gear 14 will drive the other crushing roller 11 to rotate. Subsequently, the operator can adjust the distance between the two blocking blocks 4 by driving the two blocking blocks 4 away from each other through the drive component according to the size of the material. Thus, the feeding speed of the material can be controlled at will according to the size of the material to ensure that the material is not fed too fast or too slow.

[0054] Subsequently, the personnel can put the material to be dried into the feed hopper 2. Under the blocking action of the two blocking blocks 4 and the two baffles 12, the material will fall between the two crushing rollers 11. The rotation of the two crushing rollers 11 can crush larger materials, preventing larger materials from causing wear to the disc dryer 1, thereby extending the service life of the disc dryer 1.

[0055] After the material in the disc dryer 1 is dried, it will be discharged to the outside through the discharge pipe 15. When it is necessary to adjust the discharge direction of the discharge pipe 15, the personnel can release the limit component to the discharge pipe 15. The personnel can rotate the discharge pipe 15 to adjust the discharge direction. When the discharge pipe 15 is rotated to a suitable angle, the limit component can limit the discharge pipe 15 to ensure that the discharge direction of the discharge pipe 15 can be adjusted. The direction of the discharge pipe 15 can be flexibly adjusted according to the layout of the production workshop and the position of subsequent equipment, which can better adapt to different site conditions, make the connection between the disc dryer 1 and other equipment more reasonable, save space, and improve the space utilization rate of the workshop.

[0056] Example 2:

[0057] This embodiment provides a disc dryer for preventing wear of the packing material by hard materials. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the drive assembly includes:

[0058] A sliding groove 6 is formed on one side of a rectangular groove 3. Two sliding blocks 7 are slidably installed in the sliding groove 6. One end of each sliding block 7 passes through the sliding groove 6 and is fixed to two blocking blocks 4 respectively. A bidirectional threaded rod 8 is rotatably installed in the sliding groove 6. One end of the bidirectional threaded rod 8 passes through the two sliding blocks 7. An installation groove 9 is formed in the feed hopper 2 and located on one side of the sliding groove 6. A first motor 10 is fixedly installed in the installation groove 9. One end of the first motor 10 passes through one side of the installation groove 9 and is coaxially connected to the bidirectional threaded rod 8.

[0059] When the first motor 10 is started, the output shaft of the first motor 10 will drive the bidirectional threaded rod 8 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 8 will drive the two sliding blocks 7 to move away from each other. The two sliding blocks 7 moving away from each other will drive the two blocking blocks 4 to move away from each other. By adjusting the distance between the two blocking blocks 4, the feeding speed of the material can be controlled at will according to the size of the material, ensuring that the material is not fed too fast or too slow.

[0060] Example 3:

In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the sliding block 7 is tightly welded to the blocking block 4; the bidirectional threaded rod 8 is threadedly connected to the sliding block 7; the output shaft of the first motor 10 is rotatably connected to the feed hopper 2; and the bidirectional threaded rod 8 is provided with two sections of threads with opposite directions of rotation.

[0062] Specifically, it ensures that the movement of the sliding block 7 can drive the blocking block 4 to move, that the rotation of the bidirectional threaded rod 8 can drive the two sliding blocks 7 to move away from or towards each other, and that the output shaft of the first motor 10 can rotate normally within the feed hopper 2.

[0063] Example 4:

[0064] This embodiment provides a disc dryer for preventing hard materials from abrading the packing. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the limiting component includes:

[0065] A groove 16 is formed inside the discharge pipe 15. A limiting rod 17 is slidably installed inside the groove 16. Several limiting holes 19 are formed at the bottom of the disc dryer 1 and on the periphery of the discharge pipe 15. The top end of the limiting rod 17 passes through the top of the groove 16 and extends into one of the limiting holes 19. A spring 18 is fixedly installed at the bottom end of the limiting rod 17 and is fixed to the bottom of the groove 16. One side of the limiting rod 17 passes through the groove 16 and extends to the outside.

[0066] When it is necessary to adjust the discharge direction of the discharge pipe 15, the operator can move the limiting rod 17 downwards. The downward movement of the limiting rod 17 will compress the spring 18 and cause it to contract until the top of the limiting rod 17 moves out of the disc dryer 1. At this time, the limiting rod 17 can release the limiting rod 17 from the discharge pipe 15, and the operator can rotate the discharge pipe 15 to adjust its discharge direction. When the discharge pipe 15 is rotated to a suitable angle, the limiting rod 17 is released. Under the action of the spring 18's rebound force, the spring 18 will compress the limiting rod 17 upwards until the top of the limiting rod 17 is inserted into the corresponding limiting hole 19. At this time, the limiting rod 17 can limit the discharge pipe 15, ensuring that the discharge direction of the discharge pipe 15 can be adjusted. The direction of the discharge pipe 15 can be flexibly adjusted according to the layout of the production workshop and the position of subsequent equipment, which can better adapt to different site conditions, make the connection between the disc dryer 1 and other equipment more reasonable, save space, and improve the space utilization rate of the workshop.

[0067] Example 5:

[0068] This embodiment provides a disc dryer for preventing hard materials from abrading the filler. In addition to the technical solutions of the above embodiments, it also has the following technical features: the top end of the limiting rod 17 is inserted into the limiting hole 19, and a plurality of limiting holes 19 are distributed in a ring at equal intervals.

[0069] In this way, it is ensured that the top end of the limiting rod 17 can be inserted into the limiting hole 19, and the distribution of several limiting holes 19 is even.

[0070] Example 6:

[0071] This embodiment provides a disc dryer for preventing hard materials from abrading the filler. In addition to the technical solutions of the above embodiments, it also has the following technical features: two gears 14 mesh with each other, and the output shaft of the second motor 13 is rotatably connected to the feed hopper 2.

[0072] Specifically, it is ensured that the rotation of one gear 14 can drive the rotation of the other gear 14, and that the output shaft of the second motor 13 can rotate normally within the feed hopper 2.

[0073] Example 7:

[0074] This embodiment provides a disc dryer for preventing hard materials from abrading the filler. In addition to the technical solutions of the above embodiments, it also has the following technical features: one side of the blocking block 4 is inclined, and the top surface of the baffle 12 is inclined.

[0075] Specifically, the material is ensured to fall between the two crushing rollers 11 due to the blocking effect of the two blocking blocks 4 and the two baffles 12.

[0076] Working principle: In use, the operator can first start the second motor 13. The output shaft of the second motor 13 will drive one of the crushing rollers 11 to rotate. The rotation of one crushing roller 11 will drive one of the gears 14 to rotate. Under the meshing action, the rotation of one gear 14 will drive the other gear 14 to rotate. The rotation of the other gear 14 will drive the other crushing roller 11 to rotate. Then, the operator can start the first motor 10 according to the size of the material. The output shaft of the first motor 10 will drive the bidirectional threaded rod 8 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 8 will drive the two sliding blocks 7 to move away from each other. The two sliding blocks 7 moving away from each other will drive the two blocking blocks 4 to move away from each other. By adjusting the distance between the two blocking blocks 4, the feeding speed of the material can be controlled at will according to the size of the material, ensuring that the material is not fed too fast or too slow.

[0077] Subsequently, the personnel can put the material to be dried into the feed hopper 2. Under the blocking action of the two blocking blocks 4 and the two baffles 12, the material will fall between the two crushing rollers 11. The rotation of the two crushing rollers 11 can crush larger materials, preventing larger materials from causing wear to the disc dryer 1, thereby extending the service life of the disc dryer 1.

[0078] After the material inside the disc dryer 1 is dried, it will be discharged to the outside through the discharge pipe 15. When it is necessary to adjust the discharge direction of the discharge pipe 15, the operator can move the limit rod 17 downward. Moving the limit rod 17 downward will compress the spring 18 and retract it until the top of the limit rod 17 moves out of the disc dryer 1. At this time, the limit rod 17 can release the limit on the discharge pipe 15, and the operator can rotate the discharge pipe 15 to adjust the discharge direction. When the discharge pipe 15 is rotated to a suitable angle, the limit rod 17 is released. Under the action of the spring 18's rebound force, the spring 18 will squeeze the limiting rod 17 to move upward until the top of the limiting rod 17 is inserted into the corresponding limiting hole 19. At this time, the limiting rod 17 can limit the discharge pipe 15, ensuring that the discharge direction of the discharge pipe 15 can be adjusted. The direction of the discharge pipe 15 can be flexibly adjusted according to the layout of the production workshop and the position of subsequent equipment, which can better adapt to different site conditions, make the connection between the disc dryer 1 and other equipment more reasonable, save space, and improve the space utilization rate of the workshop.
