Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to an air-heated dryer. Background Art

[0002] Dryers are needed for drying in the production of compressed air. The characteristics of desiccant are used to effectively adsorb water molecules in the compressed air to achieve drying. Most existing dryers adopt a structure with an adsorption bin with a larger inner diameter. The adsorption bin is filled with desiccant. When compressed air enters the adsorption bin from the pipeline, the air mainly passes through the center, resulting in low utilization rate of the adsorbent on the periphery. The adsorbent needs to be replaced frequently and the drying performance is poor. A small number of dryers adopt a two-row structure with a smaller inner diameter of the cross-shaped tube, which can effectively improve the utilization rate of the dryer. When the two rows of this type of dryer work alternately, the desorption and regeneration efficiency of one of the rows is low when it stops working, resulting in unsatisfactory drying effect or low drying efficiency.

[0023] A wind heat dryer, see Figure 1-4, mainly used for drying compressed air, including a host 100, the host 100 includes a plurality of ferrules 110 filled with desiccant, a plurality of upper cavities 120 and lower cavities 130 respectively connected to the upper and lower ends of the ferrules 110, and an air outlet module 140 and an air inlet module 150 respectively connected to the upper cavity 120 and the lower cavity 130; the compressed air enters the lower cavity 130 through the air inlet module 150, and then passes through the ferrule 110. When passing through the ferrule 100, water molecules are adsorbed by the desiccant and reach the upper cavity 120 above, and finally discharged from the host 100 through the air outlet module 140. Under normal circumstances, the host can be used alone to dry the compressed air. The main unit 100 is connected to a heating box 200 with a built-in heating element. The heating element can be a heating tube or a graphene heating sheet or other heating mechanisms in different forms to generate heat in the heating box 200; the heating box 200 is connected to a high-pressure fan 210, and a pipe 22- is connected between the heating box 200 and the upper cavity 120. The pipe 220 is provided with at least one solenoid valve 221. When the high-pressure fan 210 is working, it supplies air to one end of the heating box 200. The air is heated after entering the heating box 200. At this time, the solenoid valve 221 is opened, and the air can then be input into the upper cavity 120 through the pipe 220, thereby realizing the function of inputting hot air into the upper cavity 120, so as to perform air-heat drying treatment on the desiccant inside the upper cavity 120 or in the cross-shaped tube 110, thereby improving the drying efficiency of the dryer.

[0024] Furthermore, the cross tubes 110 are arranged in multiple rows, such as Figure 1As shown, under normal circumstances, the ferrules are arranged in two rows as in the present embodiment, and each row is provided with a plurality of ferrules 110, and the upper and lower ends of the ferrules 110 in each row are respectively connected to the same upper cavity 120 and lower cavity 130, and the ferrules 110 are hollow tubular structures, and the ferrules 110 are filled with desiccant, and the desiccant is generally made of aluminum oxide particles, and the upper cavity 120 and the lower cavity 130 are respectively provided with through holes corresponding to the ferrules 110, so that the gas can flow through; The pipe 220 includes an output end 222 connected to the heating box 200 and an input end 223 close to the upper cavity 120. The input end 223 can form a branch from the end of the output end 222 corresponding to the number of upper cavities 120. For example, in this embodiment, the cross-shaped pipes 110 are distributed in two rows, and the upper ends of the two rows of cross-shaped pipes 110 are connected to the upper cavity 120. Therefore, the input end 223 is divided into two branches from the output end 222, and the two branches are respectively connected to the two upper cavities 120; The magnetic valve 221 is arranged on each branch of the input end 223 to control the air flow state of each branch respectively; when the host 100 is working, the compressed air enters the host 100 and enters the two rows of the ferrule 110 through the lower cavity 130 respectively. Under program control, the compressed gas can be allowed to pass through the two rows of the ferrule 110 alternately to achieve alternating operation. When the compressed air flows in one row of the ferrule 110 for drying, the electromagnetic valve 221 on the branch of the input end 223 connected to the upper cavity 120 corresponding to the other row of the ferrule 110 is opened, and the high-pressure blower 210 starts to supply air. The hot air can enter the connected upper cavity 120 through the branch corresponding to the input end 223. When the hot air passes through, the water molecules that may remain in the upper cavity 120 are removed and the desiccant in the ferrule 110 is desorbed and regenerated. In this way, one row of the ferrule 110 absorbs moisture and the other row of the ferrule 110 desorbs and regenerates. In this way, the continuous cycle works to achieve high-efficiency drying of the compressed air.

[0025] Furthermore, a one-way valve 224 is provided at one end of the pipe 220 close to the heating box 200, and the one-way valve 224 can prevent the gas from flowing back and forth, thereby ensuring the flow direction and stability of the gas; the air inlet module 150 is provided with an air inlet 151, and the air outlet module 140 is provided with an air outlet 141. The undried compressed air enters the main unit 100 through the air inlet 151, and the dried compressed air is output from the main unit through the air outlet 141. One side of the air inlet module 150 is connected to the two upper cavities 120 at the same time, and the air outlet module 140 is connected to the two upper cavities 120 at the same time. One side of the block 140 is connected to the two lower cavities 130 at the same time, so the air exhausted from the two upper cavities 120 can be output from the main unit through the air outlet 141. Similarly, the compressed air enters the air inlet module 150 through the air inlet 151 and can enter the two lower cavities 120 respectively; the air inlet module 150 is provided with two cylinders 152 corresponding to the lower cavities 130, and the two cylinders 151 correspond to the two lower cavities 130. The two cylinders 152 are opened alternately to realize the alternating operation of the two rows of cross-shaped pipes 110 on the main unit 100.

[0026] Furthermore, the upper cavity 120 and the lower cavity 130 are provided with through holes that can connect the air outlet module 140 or the air inlet module 150 and the cross-shaped pipe 110 to allow the internal air to circulate, and the upper cavity 120 is provided with an air inlet hole 121 connected to the pipe 220, and the two upper cavities 120 are provided with an air inlet hole 121, and each air inlet hole 121 is connected to a branch of an input end 223 on a pipe 220; a control box 160 is provided on the front side of the host 100, and a control circuit board is provided in the control box 160, and the operation of the host 100 is controlled by the control circuit board. A controller 161 and a pressure gauge 162 connected to the control circuit board are provided on the surface of the control box 160, and the pressure gauge 162 can allow the user to observe the real-time pressure status, and the controller 161 can allow the user to change or adjust the working status of the host 100; the host 100 is provided with a muffler 170 connected to the lower cavity 130, and the muffler 170 can reduce the noise when the host 100 is working.
