Description

Technical Field

[0001] This utility model relates to a wet material drying pipe structure, and more specifically, to a wet material drying pipe structure for sodium metabisulfite dehydration. Background Technology

[0002] Sodium metabisulfite dehydrated wet material is conveyed and dried using hot airflow. During the drying process, some material is affected by gravity, which exceeds the buoyancy of the airflow, causing the material to settle at the bottom of the airflow inlet duct. This continuous accumulation not only requires manual cleaning of the conveying waste (2 hours per shift), but also reduces airflow and consequently lowers production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a sodium metabisulfite dehydration wet material drying pipe structure that reduces the amount of powder entering the air duct and facilitates waste cleaning.

[0004] The technical solution of this utility model is implemented as follows: a drying pipe structure for dehydrated wet sodium metabisulfite includes a vertically arranged drying pipe and a screw feeder connected to the drying pipe. The bottom of the drying pipe is connected to a right-angle air supply pipe that is connected to an external hot air source. A horn-shaped pipe with a gradually decreasing diameter is provided between the right-angle air supply pipe and the drying pipe.

[0005] A storage pipe for storing fallen powder is connected to the bottom of the corner section of the right-angle air supply pipe. A guide plate is provided on the horizontal section of the right-angle air supply pipe, with the front end of the guide plate located above the opening end of the storage pipe. A discharge component is provided at the bottom of the storage pipe.

[0006] In the above-mentioned structure of a drying pipe for dehydrated sodium metabisulfite, a fan plate is provided in the vertical section of the right-angle air supply pipe via a rotating shaft, and the front end of the fan plate is located on the side of the rotating shaft away from the air inlet. When hot air is blown out along the fan plate, the fan plate rotates and throws the falling powder towards the inner wall of the right-angle air supply pipe on the side away from the air inlet.

[0007] In the above-mentioned sodium metabisulfite dehydration wet material drying pipeline structure, the end of the air guide plate is provided with an elastic impact component that cooperates with the end of the wind turbine plate.

[0008] In the above-mentioned structure of a drying pipe for dehydrated wet sodium metabisulfite, the elastic impact component includes a hinge seat disposed at the end of the air guide plate, a swing rod hinged to the hinge seat, a return spring disposed between the end of the air guide plate and the swing rod, and a limiting block disposed on the side of the hinge seat away from the air inlet.

[0009] In the above-mentioned structure of a drying pipeline for dehydrated wet sodium metabisulfite, the storage pipe is a square pipe, the discharge assembly includes a discharge plate at the bottom of the storage pipe, hanging rings are hinged on the outer walls on both sides of the discharge plate, and hanging ears corresponding to the hanging rings are provided on the bottom outer wall of the storage pipe; a baffle assembly is provided above the storage pipe, which closes when the discharge plate is removed.

[0010] In the above-mentioned structure of a drying pipeline for dehydrated sodium metabisulfite, the baffle assembly includes a rotary valve plate disposed inside the storage pipe, a push rod hinged to the bottom of one side of the rotary valve plate, a counterweight on the push rod, and a limiting block that cooperates with the rotary valve plate on the inner wall of the storage pipe; when the discharge plate is installed at the bottom of the storage pipe, the push rod contacts the bottom surface of the discharge plate and pushes the rotary valve plate to an inclined state.

[0011] In the above-mentioned structure of a drying pipe for dehydrated wet sodium metabisulfite, the discharge end of the screw feeder is located inside the drying pipe near the central axis, and a downward-curved guide section is provided at the end of the screw feeder.

[0012] By adopting the above structure, this utility model increases the air pressure and improves the air speed through the gradually narrowing horn tube, providing sufficient air speed for drying wet materials and reducing the falling of wet materials.

[0013] By setting up a guide vane to reduce the pipe diameter and increase the hot air velocity, the hot air is guided to one side of the vertical section of the right-angle air supply pipe. When powder falls, it will fall behind the guide vane under the influence of the hot air and then enter the storage pipe for collection, reducing the accumulation of powder in the right-angle air supply pipe and affecting air supply. At the same time, the discharge component facilitates cleaning. Attached Figure Description

[0022] See Figure 1-5 As shown, this utility model discloses a drying pipe structure for dehydrated wet sodium metabisulfite, comprising a vertically arranged drying pipe 1 and a screw feeder 2 connected to the drying pipe 1. A right-angle air supply pipe 3, connected to an external hot air source, is connected to the bottom of the drying pipe 1. A flared pipe 4 with a gradually decreasing diameter is provided between the right-angle air supply pipe 3 and the drying pipe 1. The upper end of the drying pipe is connected to an external powder collection assembly or the next processing step via a pipe, and the right-angle air supply pipe is connected to the external hot air source. The gradually decreasing diameter flared pipe increases the air pressure and improves the air velocity, with the upper diameter of the flared pipe being approximately half the diameter of the lower diameter, providing sufficient air velocity for drying the wet material and reducing wet material falling off.

[0023] A storage pipe 5 for storing fallen powder is connected to the bottom of the corner section of the right-angle air supply duct 3. An air guide plate 6 is installed on the horizontal section of the right-angle air supply duct 3, with its front end positioned above the opening of the storage pipe 5. A discharge assembly 7 is located at the bottom of the storage pipe 5. By setting the air guide plate, the pipe diameter is reduced, increasing the hot air velocity and guiding the hot air to one side of the vertical section of the right-angle air supply duct. When powder falls, it is influenced by the hot air and falls towards the side behind the air guide plate, then enters the storage pipe for collection, reducing powder accumulation in the right-angle air supply duct and its impact on airflow. Simultaneously, the discharge assembly facilitates cleaning.

[0024] In this embodiment, a fan plate 8 is installed within the vertical section of the right-angle air supply duct 3 via a rotating shaft, and the front end of the air guide plate 6 is located on the side of the rotating shaft away from the air inlet. When hot air is blown out along the air guide plate 6, the fan plate 8 rotates, throwing the falling powder towards the inner wall of the right-angle air supply duct 3 on the side away from the air inlet. By blocking and guiding the powder falling from above with the fan plate, it is possible to further prevent the powder from falling into the right-angle air supply duct and to better guide the powder to the storage pipe for collection. At the same time, after setting the fan plate, the front end of the air guide plate can be installed on the side away from the air inlet, ensuring that there is a sufficiently large opening in the right-angle air supply duct for air delivery.

[0025] In this embodiment, preferably, the end of the air guide plate 6 is provided with an elastic impact component 9 that cooperates with the end of the windmill plate 8. When the windmill plate rotates close to the air guide plate, its end impacts the elastic impact component, slowing down or even stopping the rotation speed of the windmill plate. This allows sufficient time for the powder on its surface to be poured into the storage pipe between the inner wall of the air guide plate and the right-angle air supply pipe on the side away from the air inlet, preventing the powder from entering the air inlet side of the right-angle air supply pipe as the windmill plate rotates. At the same time, the impact between the end of the windmill plate and the elastic impact component causes the windmill plate to vibrate, shaking off the powder adhering to its surface.

[0026] More preferably, the elastic impact assembly 9 includes a hinge seat 9a disposed at the end of the wind guide plate 6, a swing rod 9b hinged to the hinge seat 9a, a return spring 9c disposed between the end of the wind guide plate 6 and the swing rod 9b, and a limiting block 9d disposed on the side of the hinge seat 9a away from the air inlet end. When the end of the wind turbine plate impacts the swing rod, the swing rod swings forward to make way, avoiding affecting the rotation of the wind turbine plate. After the wind turbine plate passes, the swing rod returns to the vertical state cooperating with the limiting block under the action of the return spring, waiting for the next collision. The return spring and the swing rod need to be set according to the placement force of the wind turbine plate, so as not to affect the rotation of the wind turbine plate while allowing the swing rod to return to its original position.

[0027] In this embodiment, the storage tube 5 is a square tube, and the discharge assembly 7 includes a discharge plate 7a disposed at the bottom of the storage tube 5. Hanging rings 7b are hinged to the outer walls on both sides of the discharge plate 7a, and hanging ears 7c corresponding to the hanging rings 7b are provided on the bottom outer wall of the storage tube 5. A baffle assembly 10 is provided above the storage tube 5, which closes when the discharge plate 7a is removed. This structure facilitates the disassembly and assembly of the discharge plate. Since the discharge plate is located at the bottom of the storage tube, it can be removed vertically downwards during disassembly, ensuring that any powder adhering to the storage tube falls onto the discharge plate. When the discharge plate is removed, the baffle assembly closes the storage tube, preventing residual powder from falling to the ground from the storage tube opening.

[0028] More preferably, the baffle assembly 10 includes a rotary valve plate 10a disposed inside the storage pipe 5, a push rod 10b hinged to the bottom of one side of the rotary valve plate 10a, a counterweight 10c disposed on the push rod 10b, and a limiting block 10d cooperating with the rotary valve plate 10a disposed on the inner wall of the storage pipe 5; when the discharge plate 7a is installed at the bottom of the storage pipe 5, the push rod 10b contacts the inner bottom surface of the discharge plate 7a and pushes the rotary valve plate 10a upward to an inclined state. This structure facilitates synchronous operation of the baffle assembly and the discharge plate, reduces additional operation time, and improves discharge efficiency.

[0029] In this embodiment, preferably, the discharge end of the screw feeder 2 is located inside the drying pipe 1 near the central axis, and a downwardly curved guide section 11 is provided at the end of the screw feeder 2. With this structure, the wet material to be dried can be guided as close as possible to the central axis of the drying pipe, avoiding contact between the wet material and the inner wall of the drying pipe, and reducing the possibility of the wet material adhering to the inner wall of the drying pipe.

[0030] During operation, the right-angle air supply duct is connected to an external hot air source to continuously supply hot air. The dehydrated wet sodium metabisulfite material to be dried is conveyed into the drying pipe through a screw feeder. The hot air is accelerated through a horn pipe and then enters the drying pipe to dry the wet material and blows it upward into the external powder collection component or the next process.

[0031] During the drying process, some of the heavier powder falls off and, guided by the air guide plate and the fan plate, enters the storage pipe and is collected by the discharge plate. After a certain period of operation, the discharge plate is removed for cleaning.

[0032] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
