Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and specifically to a ventilation structure for a dryer. Background Technology

[0002] A dryer is a device that removes moisture from materials by means of heating, ventilation, or dehumidification. It is widely used in industries such as food, chemical, pharmaceutical, textile, and wood processing.

[0003] Currently, ventilation is generally required during the operation of a dryer. Forced ventilation is used to expel hot and humid air while drawing in fresh and dry air to improve drying efficiency and prevent moisture from recondensing.

[0004] However, current ventilation structures are simple, generally consisting of an exhaust pipe and a filter bag installed on the exhaust pipe. Hot, humid air is discharged through the exhaust pipe, while impurities in the hot air are filtered out by the filter bag. However, the installation of the filter bag is quite troublesome, and it is not possible to quickly replace the bag while the machine is running. Replacement is required when the machine is stopped. Furthermore, during the replacement process, because the opening of the filter bag is in an open state, impurities inside the filter bag can easily drift to the outside, causing indoor pollution and affecting the personnel who are replacing the filter bag. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a ventilation structure for a dryer that allows for the replacement of filter bags by rotation and covers the bag openings of the filter bags by a cover plate, thereby solving the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a ventilation structure for a dryer, including an adjusting plate, a panel, and a ventilation pipe connected to the exhaust end of the dryer. One end of the ventilation pipe expands outward to form a cover, which is installed on the panel. The adjusting plate and the panel are arranged in parallel contact. The adjusting plate has a mounting groove opposite to each other, and a mounting plate is provided in the mounting groove. Each mounting plate has an exhaust hole, one of which is opposite to the cover. A filter bag is installed on the end of the exhaust hole away from the cover. Each mounting plate has a cover plate installed by a hinge. A limiting rod is sleeved on the outside of the adjusting plate to restrict the mounting plate in the mounting groove.

[0007] As a preferred technical solution, the limiting rod is set in a "C" shape, and the opening on the limiting rod forms a disassembly and assembly port for the mounting plate to enter and exit. Multiple fixing brackets are installed between the limiting rod and the panel, and the interior of the fixing brackets forms a space for the cover plate to pass through.

[0008] As a preferred technical solution, each of the inner walls of the mounting slot is provided with a positioning slot, which is set in a "U" shape. Each of the sides of the mounting plate protrudes to form a positioning part that matches the positioning slot, and the positioning part is inserted into the positioning slot.

[0009] As a preferred technical solution, a mounting hole is provided at the center of the panel, a bearing is installed in the mounting hole, and a brake motor is installed on the side of the panel facing the exhaust pipe. The shaft of the brake motor passes through the inner ring of the bearing and is fixedly connected to the adjusting plate.

[0010] As a preferred technical solution, the mounting plate is provided with an annular groove on the side facing the cover. The annular groove is located outside the exhaust hole. A rubber ring is installed in the annular groove, and the rubber ring opposite to the cover is set to abut against the end face of the cover.

[0011] As a preferred technical solution, all hinge components are damped hinges.

[0012] As a preferred technical solution, the diameter of the cover plate is larger than the inner diameter of the vent hole.

[0013] As a preferred technical solution, the outer ring surface of the mounting plate is in contact with the inner ring surface of the limiting rod.

[0014] The beneficial effects of this utility model are: the utility model has a simple structure, and the replacement between the upper and lower filter bags can be completed quickly through the rotating adjustment plate without stopping the machine, which increases efficiency. During the rotation, the opening of the filter bag is always blocked by the panel, which avoids the exposure of impurities inside the filter bag. After the mounting plate and the disassembly port are aligned, the mounting plate and filter bag can be directly removed. The cover plate can quickly block the opening of the filter bag, greatly reducing the probability of impurities being exposed and improving the replacement efficiency. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ventilation structure of a dryer according to this utility model includes an adjusting plate 2, a panel 1, and a ventilation pipe connected to the exhaust end of the dryer. One end of the ventilation pipe expands outward to form a cover 3, which is installed on the panel 1. The adjusting plate 2 and the panel 1 are arranged in parallel contact. The adjusting plate 2 is provided with a mounting groove 14, and a mounting plate 7 is provided in the mounting groove 14. Each mounting plate 7 is provided with an exhaust hole 12, one of which is arranged opposite to the cover 3. A filter bag 10 is installed on the end of the exhaust hole 12 away from the cover 3. Each mounting plate 7 is provided with a cover plate 8 by a hinge. A limiting rod 5 is sleeved on the outside of the adjusting plate 2 to restrict the mounting plate 7 in the mounting groove 14.

[0022] In this embodiment, the limiting rod 5 is arranged in a "C" shape. The opening on the limiting rod 5 forms a disassembly and assembly port for the mounting plate 7 to enter and exit. Multiple fixing brackets 9 are installed between the limiting rod 5 and the panel 1. The interior of the fixing brackets 9 forms a space for the cover plate to pass through.

[0023] In this embodiment, each of the inner walls of the mounting groove 14 is provided with a positioning groove 15, and each positioning groove 15 is arranged in a "U" shape. Each of the sides of the mounting plate 7 has a positioning part that matches the positioning groove 15. The positioning part is inserted into the positioning groove 15. The mounting plate can be positioned front and back by the insertion between the positioning part and the positioning groove.

[0024] In this embodiment, a mounting hole is provided at the center of the panel 1, and a bearing 11 is installed in the mounting hole. A brake motor 6 is installed on the side of the panel 1 facing the exhaust pipe 4. The rotating shaft of the brake motor 6 passes through the inner ring of the bearing 11 and is fixedly connected to the adjusting plate 2. After the power is cut off, the brake motor can lock itself, thereby locking and fixing the adjusting plate. The brake motor is connected to a power supply and a controller through wires, and the controller can control the drive of the brake motor.
