[0002] Internal circulation regeneration adsorption dryer is a device that uses molecular sieve or alumina as desiccant to dehydrate and dry compressed air under a certain working pressure, and can repeatedly regenerate and cycle within a specified period.

[0003] At present, a Chinese utility model with announcement number CN213761207U discloses an adsorption dryer for waste gas recycling and utilization, which relates to the technical field of dryers. The utility model includes a gas recovery device, which cools the micro-heat regeneration gas of the adsorption dryer to remove moisture, and sends this part of the gas to the inlet of the adsorption dryer through the gas recovery device to participate in the adsorption regeneration cycle drying process, thereby drying the compressed air without consuming the compressed air consumption. The comprehensive energy consumption is about 40% of the micro-heat adsorption drying with the same processing capacity, which greatly reduces the energy consumption of drying the compressed air.

[0004] However, the existing gas recovery mechanism of the internal circulation regeneration dryer cannot effectively filter and heat the gas, is not convenient for regenerating the desiccant, and is not effective for quickly disassembling and cleaning the dust filter. To solve the above problems, we provide a gas recovery mechanism for an internal circulation regeneration dryer. Utility Model Content

[0007] By adopting the above technical solution: the user can connect the connecting pipe 1 with the exhaust pipe of the dryer, so that the gas enters the interior of the filter tank through the connecting pipe 1, and then the gas is filtered through the dust filter. Subsequently, the filtered gas enters the interior of the heating tank through the connecting pipe 2, and the annular heater is started to heat the filtered gas, so that the gas can be effectively filtered and heated, and it is convenient to regenerate the desiccant. The user can rotate the dust collecting tank, remove the dust collecting tank, and it is convenient to dump the dust. The user can remove the mother buckle from the child buckle by pulling the mother buckle, and then remove the funnel, so that the dust filter can be effectively and quickly disassembled and cleaned.

[0008] The utility model is further configured that a connecting pipe 1 is provided on one side of the filter tank, and one end of the connecting pipe 1 is connected to the filter tank.

[0009] By adopting the above technical solution: by setting up a connecting pipe 1, it can be effectively connected with the dryer exhaust pipe.

[0010] The utility model is further configured that the top of the tank cover is connected with a connecting pipe 2, and the other end of the connecting pipe 2 is connected with the heating tank.

[0011] By adopting the above technical solution: by setting the connecting pipe 2, it can be effectively connected with the heating tank.

[0012] The utility model is further configured that an upper cover is arranged on the top of the heating tank, and the bottom of the upper cover is bolted to the heating tank.

[0013] By adopting the above technical solution, the upper cover can be effectively used in conjunction with the heating tank.

[0014] The utility model is further configured that a three-way pipe is arranged on the top of the upper cover, and the bottom of the three-way pipe is connected with the upper cover.

[0015] The above technical solution is adopted: by setting a three-way pipe, it can be effectively connected with the dryer AB tank.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. The user can connect the connecting pipe 1 with the exhaust pipe of the dryer, so that the gas enters the interior of the filter tank through the connecting pipe 1, and then the gas is filtered through the dust filter. Then the filtered gas enters the interior of the heating tank through the connecting pipe 2, and the ring heater is started to heat the filtered gas, so that the gas can be effectively filtered and heated, and the desiccant can be regenerated;

[0018] 2. The user can rotate the dust collecting tank to remove it and dump the dust. The user can remove it from the sub-buckle by pulling the mother buckle, and then remove the funnel, so that the dust filter can be quickly disassembled and cleaned effectively. BRIEF DESCRIPTION OF THE DRAWINGS
