Description

Technical Field

[0001] This application relates to the field of dryer atomization technology, and in particular to an atomization device suitable for combined dryers. Background Technology

[0002] A combined dryer is an industrial device that integrates two or more drying technologies to achieve complementary advantages. Its core design logic lies in overcoming the limitations of a single drying technology. The atomizing device is the core component of the combined dryer, and its typical installation location is at the top of the drying tower.

[0003] A search revealed Chinese Patent Publication No. CN220404843U, which discloses a spray dryer, including a main frame. A high-speed atomizer is installed on the top of the main frame, and the high-speed atomizer is connected to a uniform atomization device via a pipe. The interior of the main frame has a cleaning structure. A motor drives a rotating shaft to disperse the water source from the spray nozzle, making the water source evenly distributed on the inner wall of the main frame. Combined with the rotating scraper, the material particles attached to the inner wall of the main frame are cleaned and scraped off, improving the drying effect of the main frame.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0005] In this patent, the water mist sprayed from the nozzle is dispersed by the rotation of the fan and relies on airflow diffusion to achieve coverage. However, the airflow intensity is greatly affected by the ambient temperature and humidity and the internal structure of the equipment, which can easily lead to uneven distribution of water mist and dead corners. At the same time, the added motor-driven fan needs to be fixedly installed inside the dryer, which makes it occupy a large space.

[0006] Therefore, in response to the above problems, the applicant provides an atomizing device suitable for combined dryers. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides an atomizing device suitable for combined dryers.

[0008] This application provides an atomizing device suitable for a combined dryer, which adopts the following technical solution:

[0009] An atomizing device suitable for a combined dryer includes a solid insert rod and a rotatable atomizing nozzle. The rotatable atomizing nozzle is provided with a swing mechanism, which includes an electric push rod, a U-shaped frame, and a pulley.

[0013] Optionally, the inner ring of the driven gear is fixedly connected to an "L"-shaped water pipe, and multiple rotatable atomizing nozzles are installed on the "L"-shaped water pipe. A rotary joint is rotatably connected to the top of the "L"-shaped water pipe, and a water pipe is rotatably connected to the top of the rotary joint.

[0014] Optionally, one end of the "L"-shaped water pipe is fixedly connected to a fixing ring, and the outer circumferential wall of the input end of the electric push rod is fixedly inserted into the fixing ring.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses an atomizing device suitable for a combined dryer.

[0027] like Figure 1-4 As shown, an atomizing device suitable for a combined dryer includes a solid insert rod 90 and a rotatable atomizing nozzle 10. The rotatable atomizing nozzle 10 is provided with a swing mechanism, which includes an electric push rod 12, a "U"-shaped frame 13 and a pulley 14. A limiting groove 1000 is formed on the rotatable atomizing nozzle 10, and the pulley 14 is slidably connected in the limiting groove 1000. The pulley 14 is fixedly connected to the "U"-shaped frame 13, and the output end of the electric push rod 12 is fixedly connected to one end of the "U"-shaped frame 13.

[0028] The solid insert 90 is provided with a scraping mechanism, which includes a fixed rod 16, a crossbeam 17 fixedly connected to the fixed rod 16, and a scraper 18 fixedly connected to one end of the crossbeam 17.

[0029] Please see Figure 1It also includes a dryer main frame 1, the bottom of which is conical. A double-layer fixing frame 2 is snapped onto the outer circumference of the dryer main frame 1. A screw 3 is threaded onto the double-layer fixing frame 2 and extends into the dryer main frame 1. Both the double-layer fixing frame 2 and the dryer main frame 1 are provided with threaded holes. The rotating screw 3 on the threaded holes is used to connect the dryer main frame 1 and the double-layer fixing frame 2.

[0030] Please see Figure 1 A motor 4 is fixedly connected to the top of the double-layer fixed frame 2. A drive gear 5 is fixedly connected to the rotating end of the motor 4. The drive gear 5 meshes with a driven gear 6. The rotating end of the motor 4 passes through the double-layer fixed frame 2 and is rotatably connected to the double-layer fixed frame 2. The motor 4 is connected to an external power source. The motor 4 drives the drive gear 5 to rotate, and the drive gear 5 drives the driven gear 6 to rotate.

[0031] Please see Figure 2 The inner ring of the driven gear 6 is fixedly connected to an "L"-shaped water pipe 9. Multiple rotatable atomizing nozzles 10 are installed on the "L"-shaped water pipe 9. A rotary joint 8 is rotatably connected to the top of the "L"-shaped water pipe 9. A water pipe 7 is rotatably connected to the top of the rotary joint 8. The rotatable atomizing nozzle 10 is commonly used in faucets and irrigation fields and is existing technology. Its principle will not be elaborated here. One end of the water pipe 7 is connected to a water pump and an external water source. The water pump introduces water from the water pipe 7 and the "L"-shaped water pipe 9 and sprays it out through the rotatable atomizing nozzle 10.

[0032] Please see Figure 2 One end of the "L"-shaped water pipe 9 is fixedly connected to a fixing ring 11. The outer circumferential wall of the input end of the electric push rod 12 is fixedly inserted into the fixing ring 11. Each of the multiple rotatable atomizing nozzles 10 has a limiting groove 1000 on both sides. The inner ring of the pulley 14 is rotatably connected to a fixed shaft. The fixed shaft is fixedly connected to the "U"-shaped frame 13. The electric push rod 12 is connected to a power source, which is a power storage module installed on the fixing ring 11 to supply power to the electric push rod 12. The input end of the electric push rod 12 extends from the output end to move the "U"-shaped frame 13. The movement of the "U"-shaped frame 13 drives the fixed shaft of the pulley 14 to move. The pulley 14 moves in the limiting groove 1000, thereby changing the spray angle of the rotatable atomizing nozzle 10.

[0033] Please see Figure 3The "L"-shaped water pipe 9 is fixedly connected to a solid insert rod 90. A through hole 900 is provided through the solid insert rod 90. The solid insert rod 90 is inserted into a fixing rod 16. A bolt 15 is threadedly connected to the fixing rod 16. A hole matching the diameter of the solid insert rod 90 is provided at the top of the fixing rod 16. Threaded holes are provided on both sides of the hole. After the solid insert rod 90 is inserted into the bolt 15 hole, the through hole 900 is aligned with the threaded hole, and then the bolt 15 is passed through and locked to fix the two. The connection of the two by the bolt 15 facilitates the disassembly and assembly of the two so that the fixing rod 16 can be used together. At the same time, it also allows the solid insert rod 90 to rotate and drive the fixing rod 16 to rotate synchronously.

[0034] Please see Figure 3 The outer circumference of the fixed rod 16 is fixedly connected to multiple crossbeams 17 from top to bottom. One end of each crossbeam 17 is fixedly connected to a scraper 18, which contacts the inner circumference of the dryer main frame 1.

[0035] The implementation principle of an atomizing device suitable for a combined dryer according to an embodiment of this application is as follows:

[0036] S1. Turn on the electric push rod 12. The input end of the electric push rod 12 extends from the output end to move the "U"-shaped frame 13. The movement of the "U"-shaped frame 13 drives the fixed shaft of the pulley 14 to move. The pulley 14 moves in the limiting groove 1000, thereby changing the spray angle of the rotatable atomizing nozzle 10, so that multiple rotatable atomizing nozzles 10 are simultaneously fixed towards the inner circumference of the dryer main frame 1.

[0037] S2. Simultaneously start motor 4 and water pump.

[0038] S20. The water pump introduces water from the water pipe 7 and the "L"-shaped water pipe 9, and sprays the water onto the inner circumference of the dryer main frame 1 through the rotatable atomizing nozzle 10.

[0039] S21. Motor 4 drives the drive gear 5 to rotate, drive gear 5 drives the driven gear 6 to rotate, driven gear 6 drives the "L"-shaped water pipe 9, the rotatable atomizing nozzle 10, the crossbeam 17 and the scraper 18 to rotate, and the scraper 18 scrapes the inner circumference of the dryer main frame 1, thereby achieving the advantage of cleaning while spraying water.

[0040] The fixing rod 16 can be removed from the solid insert rod 90 by bolts 15, so that the electric push rod 12 can drive the rotatable atomizing nozzle 10 to swing left and right, thereby achieving the advantages of enhanced heat and mass transfer efficiency and reduced equipment wear and maintenance costs.
