Description

Technical Field

[0001] This utility model relates to the field of integrated machine technology, and more specifically, to a three-in-one dehumidifying dryer. Background Technology

[0002] The three-in-one dehumidifying dryer integrates dehumidification, drying, and two-stage feeding functions into one unit. It is particularly suitable for engineering plastic raw materials with strong hygroscopicity. By dehumidifying and drying the raw materials, it can effectively reduce phenomena such as shrinkage, silver streaks, bubbles, cracks, flow marks, and poor transparency that are prone to occur during production. Existing three-in-one dehumidifying dryers mostly use hot air circulation for drying. This method can only slowly circulate and turn the raw materials, so it cannot achieve uniform, stable, and rapid drying, resulting in low drying efficiency and low energy utilization.

[0003] Regarding the aforementioned issues, particularly the low drying efficiency of existing three-in-one dehumidifying dryers, extensive research revealed a patent (CN212658004U) for a three-in-one dehumidifying dryer. This dryer includes a body with a material cylinder on one side, a drying chamber inside the cylinder, a rotating tube rotatably connected within the drying chamber, and multiple stirring branch pipes evenly distributed on the outer surface of the rotating tube. A connecting frame is fixedly connected to the top of the material cylinder, and the top of the rotating tube is rotatably connected to the connecting frame. A feed pipe is located on one side of the top of the material cylinder. This invention, through the material cylinder, dehumidifying fan, and drying fan, can stably achieve dehumidification, drying, and secondary feeding of raw materials, effectively realizing a three-in-one working mode. The rotating tube, combined with the stirring branch pipe structure, can evenly and stably contact the drying hot air with the raw materials, ensuring stable and uniform drying, improving drying efficiency, reducing conventional operation time, and saving energy. However, the technical solution provided by this patent has the following problems:

[0004] (1) The drying method adopted by this device is to dry the material one cylinder at a time. The material is also supplied in batches and is not continuous. It is not suitable for production lines that require continuous material supply, which requires additional personnel or additional equipment to change the material supply method, which may lead to a decrease in production efficiency and an increase in costs.

[0005] (2) The gas dried by the device is directly discharged to the outside after processing. The discharged gas is heated by the heater and carries the moisture in the material, which will make the working area humid and stuffy, seriously affecting the comfort of the work.

[0006] This invention can dry and dehumidify materials and reduce the temperature and humidity of exhaust gases. Utility Model Content

[0009] The drying oven has a centrally connected drying main pipe, and several drying branch pipes are equidistantly connected around the outer end of the main drying pipe. The bottom of the drying oven is connected to a first drying plate, and a second drying plate is installed on the top of the first drying plate. Several first connecting blocks are connected to the outer end of the second drying plate, and the other end of the first connecting blocks is connected to the inner wall of the drying oven.

The other end of the second connecting blocks is connected to the inner wall of the drying oven. Several drying branch pipes are installed on the top of the first, second, and third drying plates.

[0010] A motor is installed at the top right end of the protective box. A drive shaft is installed at the output end of the motor. A drive tooth is installed at the bottom end of the drive shaft. A driven tooth is installed at the left end of the drive tooth. A drying main tube is installed in the center of the driven tooth. A sealed bearing is installed at the top of the drying main rod. An air supply pipe is connected to the top of the sealed bearing.

[0012] A further preferred embodiment: the first and third drying plates are lower in the center and higher around the perimeter, with the drying plates sloping from the perimeter towards the center; the second drying plate is higher in the center and lower around the perimeter, with the drying plate sloping from the center towards the perimeter.

[0013] A further preferred embodiment: the drying branch pipe is inclined at the same angle as the first drying plate, the second drying plate and the third drying plate at the bottom.

[0016] A further preferred embodiment: the bottom of the machine body is equipped with casters.

[0017] Beneficial effects:

[0018] 1. By setting up a drying chamber, the material is dried and dehumidified. The material is fed into the drying chamber through the feed pipe and falls onto the third drying plate. Then, the motor is started, which makes the main drying pipe rotate and drives the branch drying pipe to rotate. The stirring rod on the main drying pipe stirs the material, turns it over, and moves it along the inclined drying plate. The material moves along the third drying plate towards the center of the third drying plate and then falls onto the second drying plate. It then falls along the second drying plate from the periphery of the second drying plate onto the first drying plate and finally falls into the discharge pipe from the center of the first drying plate. This drying and dehumidification method can continuously dry the material and is suitable for some production lines that require uninterrupted material supply.

[0019] 2. By incorporating a condenser, water pump, and cooling water tank, the temperature and humidity of the exhaust gas are reduced. During drying, the hot gas is discharged from the hot gas pipe into the water storage tank. As the hot gas passes through the condenser, the water pump is activated, continuously pumping cold water into the condenser. This lowers the temperature of the hot gas pipe and cools the water vapor inside, causing it to flow into the water storage tank. Finally, the cooled gas is discharged from the water storage tank. The reduced temperature and moisture content of the gas after passing through the condenser effectively prevent the exhaust gas from making the working environment stuffy.

[0020] 3. In summary, this three-in-one dehumidifying dryer, with its structure including a drying chamber, condenser pipe, water pump, and cooling water tank, can dry and dehumidify materials and reduce the temperature and humidity of exhaust gases. Attached Figure Description

Depending on actual needs, the size and number of drying plates and the number of drying branch pipes 24 can be increased, rather than being limited to the number and size shown in the attached figure.

[0029] A motor 5 is installed at the right end of the top of the protective box 3. A drive shaft 13 is installed at the output end of the motor 5. A drive gear 14 is installed at the bottom end of the drive shaft 13. A driven gear 15 is installed at the left end of the drive gear 14.

[0030] In this embodiment of the present invention, the drying branch pipe 24 includes: a branch pipe body 2401, a stirring rod 2402, and a jet nozzle 2403; a plurality of branch pipe bodies 2401 are equidistantly connected around the outer end of the drying main rod, a plurality of equidistantly distributed stirring rods 2402 are installed at the bottom end of the branch pipe body 2401, and a plurality of equidistantly distributed jet nozzles 2403 are also installed at the bottom end of the branch pipe body 2401.

[0034] In this embodiment of the invention, the condenser tube 19 is installed at a 45-degree angle at the front end of the cooling water tank 17 to increase the length of the condenser tube 19, thereby enhancing the cooling capacity.

[0035] In this embodiment of the utility model, a universal wheel 11 is installed at the bottom of the body 1 to facilitate the movement of the body 1.

[0036] Working principle: In use, first, start the heater 6 and blower 7 to generate hot air, which enters the main drying pipe 29 through the air supply pipe 4. Then, the hot air is ejected from the nozzle 2403 of the drying branch pipe 24. Next, the material is fed in through the feed pipe 2 and enters the drying chamber 22, falling onto the third drying plate 28. Then, start the motor 5, which drives the drive shaft 13 to rotate, which in turn drives the drive gear 14 to rotate. The drive gear 14 drives the driven gear 15 to rotate, causing the main drying pipe 29 to rotate as well, which in turn drives the drying branch pipe 24 to rotate. This stirs the material through the stirring rod 2402 on the main drying pipe 29, causing the material to turn over and move along the inclined drying plate. At this time, the material will move along the third drying plate 28 towards the center of the third drying plate 28 and then fall onto the drying plate 28. On the second drying plate 26, the material falls from around the second drying plate 26 onto the first drying plate 23, and finally falls from the center of the first drying plate 23 into the discharge pipe 12. This drying and dehumidifying method can continuously dry materials and is suitable for some production lines that require uninterrupted material supply. During drying, the hot air is discharged from the hot air pipe 18 into the water storage tank 21. When the hot air pipe 18 passes through the condenser pipe 19, the water pump 20 is started. The water pump 20 continuously pumps cold water into the condenser pipe 19, which lowers the temperature of the hot air pipe 18 and cools the water vapor in the hot air pipe 18, causing it to flow into the water storage tank 21. Finally, the cooled gas is discharged from the water storage tank 21. After passing through the condenser pipe 19, the gas temperature and water vapor content decrease, which can effectively prevent the discharged gas from making the working environment stuffy.
