Description

Technical Field

[0001] This utility model relates to the field of dryer door cover technology, and in particular to a door cover for a dryer. Background Technology

[0002] Dryers are key pieces of equipment in industrial production used to remove moisture from materials. Their doors and covers, as crucial components for sealing the drying chamber, directly impact the equipment's energy consumption, efficiency, and product quality. Existing dryer doors and covers primarily function to achieve simple opening and closing and basic sealing.

[0003] However, such covers still have shortcomings when dealing with high humidity conditions. During circulation, the high-temperature, humid air inside the dryer easily comes into contact with the relatively cool inner surface of the cover, causing condensation into tiny droplets or liquid films. This not only creates conditions for material contamination but also reduces the heat transfer efficiency in the cover area, affecting drying uniformity.

[0004] Therefore, we propose a door cover for the dryer. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a door cover for a dryer, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a door cover for a dryer, comprising a door cover with an opening at the bottom, an inner sealing door plate installed on one side of the opening at the bottom of the door cover, a first fixing plate and a second fixing plate respectively installed on both sides of the door cover, a fixing block fixedly installed on the door cover, an installation block fixedly installed on the second fixing plate, a rotating rod hinged inside the installation block, a connecting rod installed on the top of the rotating rod, and a rotating cover plate installed through the connecting rod, an installation box installed on the top of the fixing block, a drive motor and a power supply unit installed inside the installation box, a rotating sleeve installed through the inner sealing door plate by the output shaft of the drive motor, a plurality of cantilever arms installed on the rotating sleeve, and a plurality of scrapers installed on the cantilever arms.

[0007] In a preferred embodiment, the present invention can be further configured such that the scrapers are staggered on both sides of the cantilever, and the bottom of the scrapers is in contact with the surface of the inner sealing door panel.

[0008] In a preferred embodiment, the present invention can be further configured such that: a first drain pipe is installed on the side of the inner sealing door panel away from the opening; the first drain pipe is hollow and L-shaped; an air inlet is provided on the first drain pipe; and an inclined air guide plate is provided inside the first drain pipe.

[0009] In a preferred embodiment, the present invention can be further configured such that a second drain pipe is installed on the side of the door cover near the opening, the second drain pipe extending into the interior of the opening and having an air outlet.

[0010] In a preferred embodiment, the present invention can be further configured such that: a mounting bracket is provided inside the opening, and a first guide pipe and a second guide pipe are mounted inside the opening via the mounting bracket, both the first guide pipe and the second guide pipe being arc-shaped.

[0011] In a preferred embodiment, the present invention can be further configured such that the interior of both the door cover and the rotating cover is hollow, and an electric heating wire is provided inside both the door cover and the rotating cover.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 A door cover for a dryer includes a door cover 1. The bottom of the door cover 1 has an opening 21. An inner sealing door plate 23 is welded to the bottom of the door cover 1 on one side of the opening 21. A drive shaft hole is opened in the middle of the inner sealing door plate 23. A first fixing plate 2 and a second fixing plate 6 are welded to the two sides of the door cover 1, respectively. A fixing block 3 is integrally formed on the door cover 1. An mounting block 7 is threaded on the second fixing plate 6. A rotating rod 8 is hinged between the mounting blocks 7. A connecting rod 9 is welded to the top of the rotating rod 8, and a rotating cover plate 10 is welded through the connecting rod 9. An installation box 4 is welded to the top of the fixing block 3. A drive motor 24 and a power supply unit 25 are fixedly installed in the installation box 4. The output shaft of the drive motor 24 passes through the inner sealing door plate 23, and a rotating sleeve 14 is installed on the output shaft of the drive motor 24 through a coupling. Several cantilever arms 15 are welded on the rotating sleeve 14, and several scrapers 16 are installed on the cantilever arms 15.

[0018] Furthermore, scrapers 16 are staggered on both sides of the cantilever 15, and the bottom of scrapers 16 is in contact with the inner sealing door panel 23.

[0019] The inner sealing door panel 23 is threaded with a first drainage pipe 11 on the side away from the opening 21. The first drainage pipe 11 is hollow inside and has an air inlet 12. The first drainage pipe 11 is L-shaped and has an air guide plate 13 inside. The air guide plate 13 is inclined.

[0020] A second drain pipe 17 is welded to the side of the door cover 1 near the opening 21. The second drain pipe 17 extends into the interior of the opening 21 and an air outlet 22 is installed therein. Two mounting brackets 19 are welded inside the opening 21, and a first guide pipe 18 and a second guide pipe 20 are respectively installed through the mounting brackets 19. Both the first guide pipe 18 and the second guide pipe 20 are arc-shaped and are located at the corners of the opening 21.

[0021] Furthermore, filters are installed on the air inlet 12, the first guide pipe 18, and the second guide pipe 20 to prevent materials from entering the first guide pipe.

[0022] Furthermore, the interior of the door cover 1 and the rotating cover plate 10 is hollow. The power supply unit 25 installed in the mounting block 7 is electrically connected to a power line 5. The power line 5 includes a main line and two branch lines. One of the branch lines of the power line 5 extends into the interior of the door cover 1 and is connected to an electric heating wire 26. The electric heating wire 26 is set close to the inner sealing door plate 23.

[0023] An electric heating wire 26 is also installed inside the rotating cover 10, and a branch of another power line 5 extends into the interior of the rotating cover 10 and is electrically connected to the electric heating wire 26.

[0024] Working principle: When in use, this device closes and rotates the cover plate 10, and seals it with a sealing ring and annular sealing ring to ensure that the door cover 1 is completely sealed. When heating and processing inside the dryer, in order to avoid the formation of tiny condensate films and keep the overall inner surface of the door cover clean and heat exchange capacity, the drive motor 24 controls the cantilever 15 to rotate, which in turn drives the scrapers 16 installed on both sides of the cantilever 15 to contact the inner sealing door plate 23, breaking the liquid film formed on the inner sealing door plate 23. At the same time, the rotation of the cantilever 15 agitates the hot air near the door cover 1 and promotes airflow circulation. The power supply unit 25 supplies power to all the electric heating wires 26 via the power cord 5. The electric heating wires 26 generate heat, uniformly heating the entire door cover body 1 and the rotating cover plate 10, maintaining their surface temperature above the dew point; The hot air circulating inside the dryer enters the first guide pipe 11 through the air inlet 12. The internal air guide plate 13 guides and rectifies the airflow, causing it to blow towards the inner sealing door plate 23, thereby increasing the surface temperature of the inner sealing door plate 23. At the same time, the hot air enters the interior of the opening 21 through the second guide pipe 17 for hot air circulation.
