Description

Technical Field

[0001] This utility model relates to the field of color masterbatch drying technology, and in particular to a drying device for color masterbatch processing. Background Technology

[0002] In the production and processing of color masterbatch, the drying process is a crucial step, as its effectiveness directly affects the quality of the masterbatch and its subsequent processing performance. Traditional color masterbatch drying equipment has revealed many problems in practical applications, severely restricting production efficiency and product quality.

[0003] Traditional drying equipment typically uses natural drainage or direct heating with hot air in the initial dehydration stage. This causes the masterbatch to clump together, making it difficult to remove moisture quickly and effectively, resulting in excessively long initial dehydration times. This not only prolongs the entire drying cycle and reduces production efficiency, but also, during the prolonged dehydration process, the masterbatch is prone to clumping due to uneven moisture retention in certain areas, affecting subsequent processing and use.

[0004] In terms of hot air supply, traditional drying equipment suffers from significant uneven distribution of hot air. The hot air generated by the hot air blower is difficult to deliver evenly to all parts of the drying drum, resulting in uneven heating of the masterbatch in different areas of the drying drum.

[0005] Therefore, it is necessary to design a drying device for color masterbatch processing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for color masterbatch processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A drying device for color masterbatch processing includes a casing, a cover plate installed at the upper end of the casing, a feed and exhaust pipe at the upper end of the cover plate, an air intake pipe rotatably connected to the cover plate at the upper end of the cover plate, a first rotating mechanism connected to the air intake pipe at the upper end of the cover plate, a hot air supply mechanism connected to the air intake pipe at the upper end of the cover plate, a stirring mechanism at the lower end of the air intake pipe, a drying cylinder inside the casing, water permeable holes on the side wall of the drying cylinder, a discharge pipe connected to the lower end of the drying cylinder, the discharge pipe penetrating the bottom of the casing, a support bearing installed between the side wall of the drying cylinder and the inner wall of the casing, and a second rotating mechanism connected to the drying cylinder at the upper end of the cover plate.

[0009] As a further improvement of this utility model, the first rotating mechanism includes a first motor mounted on the upper end of the cover plate, the output shaft of the first motor is fixedly connected to a second gear, and a first gear is fixedly sleeved on the side wall of the air intake pipe, the first gear meshing with the second gear.

[0010] As a further improvement of this utility model, the hot air supply mechanism includes a hot air fan installed on the upper end of the cover plate, the output end of the hot air fan is connected to a gas delivery pipe, and the end of the gas delivery pipe away from the hot air fan is connected to the upper end of the air inlet pipe through a rotating vent connector.

[0011] As a further improvement of this utility model, the stirring mechanism includes a hollow rod, which is mounted on the lower end of the air inlet pipe via a one-way bearing. A spiral stirring blade is fixedly sleeved on the side wall of the hollow rod, and a stirring rod is fixed on the side wall of the hollow rod. An air outlet is provided on the side wall of the hollow rod.

[0012] As a further improvement of this utility model, the second rotating mechanism includes a second motor mounted on the upper end of the cover plate, the output shaft of the second motor passing through the cover plate and fixedly connected to a third gear, and a gear ring fixedly sleeved on the side wall of the drying cylinder, the gear ring meshing with the third gear.

[0014] The beneficial effects of this utility model are:

This significantly shortens the initial dehydration time, improves the overall drying efficiency, and avoids the increased energy consumption caused by separation during the drying stage in traditional equipment, thus reducing the entire processing cycle.

[0016] The hot air supply mechanism is designed to connect the hot air blower to the air inlet pipe through the air delivery pipe and the rotary air connector.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A drying device for color masterbatch processing includes a housing 1, a cover plate 2 installed on the upper end of the housing 1, a feed and exhaust pipe 4 provided on the upper end of the cover plate 2, three mounting bolts 3 passing through the upper end of the cover plate 2 and screwed onto the upper end of the housing 1, a water outlet pipe 13 provided on the side wall of the housing 1, a valve installed on the water outlet pipe 13, four support columns 15 fixedly connected to the lower end of the housing 1, an air inlet pipe 5 rotatably connected to the upper end of the cover plate 2 and rotatably connected to the cover plate 2 via bearings, and a... The first rotating mechanism is connected to the air intake pipe 5. The upper end of the cover plate 2 is provided with a hot air supply mechanism connected to the air intake pipe 5. The lower end of the air intake pipe 5 is provided with a stirring mechanism. The inside of the housing 1 is provided with a drying cylinder 16. The side wall of the drying cylinder 16 is provided with a water permeable hole 17. The lower end of the drying cylinder 16 is connected to a discharge pipe 14. A valve is installed on the discharge pipe 14. The discharge pipe 14 passes through the bottom of the housing 1. A support bearing 18 is installed between the side wall of the drying cylinder 16 and the inner wall of the housing 1. The upper end of the cover plate 2 is provided with a second rotating mechanism connected to the drying cylinder 16.

[0023] In this utility model, the first rotating mechanism includes a first motor 11 installed on the upper end of the cover plate 2. The output shaft of the first motor 11 is fixedly connected to a second gear 10. A first gear 6 is fixedly sleeved on the side wall of the air intake pipe 5. The first gear 6 meshes with the second gear 10. When the first motor 11 is started, the air intake pipe 5 can be driven to rotate through the transmission of the first gear 6 and the second gear 10.

[0024] The hot air supply mechanism includes a hot air blower 9 installed on the upper end of the cover plate 2. The output end of the hot air blower 9 is connected to a gas supply pipe 8. The end of the gas supply pipe 8 away from the hot air blower 9 is connected to the upper end of the air inlet tube 5 through a rotary vent connector 7. By starting the hot air blower 9, hot air can be supplied to the air inlet tube 5 and the hollow rod 21 through the gas supply pipe 8. Then, hot air is supplied to the masterbatch inside the drying cylinder 16 through the air outlet 22 to dry the masterbatch.

[0025] The stirring mechanism includes a hollow rod 21, which is mounted on the lower end of the air inlet rotary pipe 5 via a one-way bearing 23. A spiral stirring blade 25 is fixedly sleeved on the side wall of the hollow rod 21, and a stirring rod 24 is fixed on the side wall of the hollow rod 21. An air outlet 22 is provided on the side wall of the hollow rod 21. By setting the one-way bearing 23, when the air inlet rotary pipe 5 is driven to rotate, the hollow rod 21 can be driven to rotate through the one-way bearing 23, thereby driving the stirring rod 24 and the spiral stirring blade 25 to rotate, turning the masterbatch and improving the efficiency of hot air drying of the masterbatch. When the drying cylinder 16 is driven to rotate and spray water, the hollow rod 21 will rotate with the drying cylinder 16. By utilizing the free rotation of the one-way bearing 23, the hollow rod 21 will not drive the air inlet rotary pipe 5 to rotate, thus avoiding interference between the hollow rod 21 and the air inlet rotary pipe 5.

[0026] The second rotating mechanism includes a second motor 12 mounted on the upper end of the cover plate 2. The output shaft of the second motor 12 passes through the cover plate 2 and is fixedly connected to a third gear 20. A gear ring 19 is fixedly sleeved on the side wall of the drying cylinder 16. The gear ring 19 meshes with the third gear 20. By starting the second motor 12, the drying cylinder 16 can be driven to rotate by the transmission between the third gear 20 and the gear ring 19. Then, by using centrifugal force, the water in the masterbatch inside the drying cylinder 16 can be quickly spun dry. When the masterbatch is then dried with hot air, the drying efficiency can be effectively improved.

[0027] When this utility model is in use, the color masterbatch is added into the interior of the drying cylinder 16 through the feed and exhaust pipe 4. Then, the second motor 12 is started, and its output shaft drives the third gear 20 to rotate. Through the meshing transmission of the gear ring 19 fixedly sleeved with the side wall of the drying cylinder 16, the drying cylinder 16 is driven to rotate. Due to centrifugal force, the water in the color masterbatch is thrown out through the water permeable hole 17 on the side wall of the drying cylinder 16 and collected. Finally, it is discharged through the water outlet pipe 13 set on the side wall of the casing 1, completing the initial centrifugal dehydration.

[0028] Next, the hot air blower 9 is started, and the hot air it generates is transported through the air supply pipe 8 and enters the air intake pipe 5, which passes through the cover plate 2 and is rotatably connected to it, through the rotary vent connector 7. At this time, the first motor 11 is started, and its output shaft drives the second gear 10 to rotate. By meshing with the first gear 6 fixedly sleeved on the side wall of the air intake pipe 5, the air intake pipe 5 is driven to rotate. The hot air enters the hollow rod 21 in the stirring mechanism sleeved at its lower end from the lower end of the air intake pipe 5, and is discharged from the air outlet 22 opened on the side wall of the hollow rod 21. At the same time, the rotation of the air intake pipe 5... The hollow rod 21 is rotated by the one-way bearing 23 mounted on the lower end of the air inlet pipe 5, which in turn causes the stirring rod 24 fixed on the side wall of the hollow rod 21 and the spiral stirring blade 25 fixedly mounted on the side wall of the hollow rod 21 to rotate together, stirring the masterbatch inside the drying cylinder 16. Hot air is continuously sprayed from the air outlet 22 onto the stirred masterbatch for efficient drying. Excess gas is discharged through the feed exhaust pipe 4. The fully dried masterbatch is finally discharged through the discharge pipe 14 connected to the lower end of the drying cylinder 16, and the entire drying process is completed.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
