This solves the following problems that existing sintering devices for organic polymer filter materials that can simultaneously perform two sintering processes still have: after the first sintering, the sprayed product is dried to remove the moisture from the coating, and then a second sintering is performed according to a certain sintering process. However, during the drying process, it is difficult for hot air to evenly dry the coating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sintering device for organic polymer filter materials capable of simultaneous double sintering, comprising a conveyor unit, an air spraying unit externally mounted on the conveyor unit, a mold sintering unit and a robotic arm mounted on the left end of the air spraying unit, and a drying mechanism externally mounted on the air spraying unit for uniformly drying the coating during the secondary sintering, the drying mechanism comprising:

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A sintering device for organic polymer filter materials capable of simultaneous double sintering includes a conveyor unit 1, an air spraying unit 3 externally mounted on the conveyor unit 1, a mold sintering unit 4 and a robotic arm 5 mounted on the left end of the air spraying unit 3, and a drying mechanism 2 externally mounted on the air spraying unit 3 for uniformly drying the coating during the secondary sintering. The drying mechanism 2 includes:

[0026] Drying chamber unit 21 is located on the right side of air spraying unit 3 and is used to form a drying chamber;

[0027] Hot air unit 22 is located at the rear of drying chamber unit 21 and is used to provide hot air;

[0028] The rotating unit 23 includes a set of rotating sleeves 231. A connecting pipe 232 is fixedly installed inside the rotating sleeve 231. An air distribution box 234 is fixedly installed at the inner end of the connecting pipe 232. Air outlet pipes 235 are fixedly installed on both sides of the air distribution box 234. A secondary pulley 233 is fixedly installed outside the connecting pipe 232. The secondary pulley 233 is driven by the driving component 6 to rotate the connecting pipe 232, thereby achieving uniform drying of the coating on the material surface.

[0029] The mold sintering unit 4 sintersects various shapes and specifications of support materials, such as tubular and plate types, required for spraying. The materials are placed above the conveyor unit 1 by the robotic arm 5. The conveyor unit 1 drives the rollers to rotate via a motor and sends the materials into the air spraying unit 3. After the prepared spray paint liquid is ultrasonically defoamed, it is sent into the spray gun. With the help of compressed air, the paint is dispersed into uniform and fine droplets and adheres to the surface of the support. By controlling the pressure and flow of compressed air, the distance between the spray gun and the support, the spraying time, and other factors, a uniform and controllable coating is finally applied to the surface of the support.

[0030] The rotating sleeve 231 is driven to rotate by the driving component 6. The rotating sleeve 231 drives the air distribution box 234 and the air outlet pipe 235 to rotate. The air outlet pipe 235 provides hot air through the hot air unit 22 to perform rotational drying on the material surface, thereby achieving uniform drying.

[0031] In this embodiment, the drying chamber unit 21 includes a mounting bracket 211 fixedly installed at the right end of the air spraying unit 3. A drying box 212 is fixedly installed at one end of the mounting bracket 211, and a rotating sleeve 231 is rotatably installed inside the top and bottom plates of the drying box 212.

[0032] In this embodiment, the drive assembly 6 includes a rotating shaft 61 rotatably installed inside the drying chamber 212, a set of drive pulleys 62 fixedly installed on the surface of the rotating shaft 61, and a large bevel gear 64 fixedly installed on the surface of the rotating shaft 61.

[0033] In this embodiment, a belt 63 is fitted between the drive pulley 62 and the secondary pulley 233 to transmit power to the rotating sleeve 231.

[0034] The belt 63, which is fitted between the drive pulley 62 and the secondary pulley 233, is used to drive the rotating sleeve 231.

[0035] In this embodiment, a motor 65 is fixedly installed on the front side of the drying box 212. The output end of the motor 65 passes through the drying box 212 and is fixedly installed with a small bevel tooth 66, which meshes with a large bevel tooth 64.

[0036] Motor 65 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed via a human-operated control panel. When motor 65 runs, it drives small bevel gear 66 to rotate, which in turn drives large bevel gear 64 to rotate. Large bevel gear 64 drives shaft 61 and two drive pulleys 62 to rotate. Drive pulleys 62 drive rotating sleeve 231 to rotate synchronously via belt 63. This enables the two symmetrical rotating sleeves 231 inside the drying chamber 212 to rotate synchronously, thereby enabling the two air distribution boxes 234 and the air outlet pipe 235 to rotate synchronously, thus achieving the same drying efficiency on the upper and lower surfaces of the material.

[0037] In this embodiment, the hot air unit 22 includes a mounting plate 221 fixedly installed on the rear side of the drying box 212. A hot air blower 222 is fixedly installed on the top of the mounting plate 221. A set of air ducts 223 is fixedly installed at the output end of the hot air blower 222, and one end of the air duct 223 is rotatably connected to the outer end of the connecting pipe 232.

[0038] The hot air blower 222 is model HAM-G15A-32. It is electrically connected to an external power source and can be turned on and off via a human-operated control panel. While the rotating sleeve 231 is rotating, the hot air blower 222 runs, sending hot air through the air duct 223, connecting pipe 232, and air distribution box 234 into the interior of the air outlet duct 235. The hot air blower 222 dries the surface of the material through the air holes on the air outlet duct 235, sintering and curing the coating and making it tightly adhered to the support, thus forming a filter membrane layer that plays a filtering and separation role.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, the mold sintering unit 4 first sintersects and forms various shapes and specifications of support materials such as tubular and plate types required for spraying. The materials are then placed above the conveyor unit 1 by the robotic arm 5. The conveyor unit 1 uses a motor to drive the rollers to rotate and send the materials into the air spraying unit 3. After the prepared spraying liquid is ultrasonically defoamed, it is sent into the spray gun. With the help of compressed air, the paint is dispersed into uniform and fine droplets and adheres to the surface of the support. By controlling the pressure and flow of compressed air, the distance between the spray gun and the support, the spraying time, and other factors, a uniform and controllable coating is finally applied to the surface of the support.

[0041] Next, the coated material enters the drying chamber 212 via the conveyor unit 1. The motor 65 drives the small bevel gear 66 to rotate, which in turn drives the large bevel gear 64 to rotate. The large bevel gear 64 drives the rotating shaft 61 and the two drive pulleys 62 to rotate. The drive pulleys 62 drive the rotating sleeve 231 to rotate synchronously via the belt 63. The rotating sleeve 231 drives the air distribution box 234 and the air outlet pipe 235 to rotate. At the same time as the rotating sleeve 231 rotates, the hot air fan 222 runs, sending hot air through the air pipe 223, the connecting pipe 232, and the air distribution box 234 into the interior of the air outlet pipe 235. The hot air is then dried through the air holes on the air outlet pipe 235, sintering and solidifying the coating and making it adhere tightly to the support, thus forming a filter membrane layer that serves as a filter for separation.
