Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically, it relates to an ultrafiltration membrane fiber drying device. Background Technology

[0002] An ultrafiltration membrane is a semi-permeable polymer membrane used in ultrafiltration processes to separate polymeric colloids or suspended particles of a certain size from a solution. It is generally made of polymeric materials such as cellulose acetate, cellulose acetate esters, polyethylene, polysulfone, and polyamide. Membrane modules are typically prefabricated in various types, including tubular, plate, spiral wound, and capillary types, and multiple modules are then assembled together for use to increase the filtration area and facilitate maintenance. Ultrafiltration membrane products are made from ultrafiltration membrane fibers, which require drying during production to remove excess moisture and meet the manufacturing requirements of ultrafiltration membranes.

[0003] In the prior art, patent announcement number CN220818331U, entitled "A High-Insulation Distribution Cabinet," discloses an ultrafiltration membrane fiber drying device, including a support frame. A cylinder is fixedly connected to the top of the support frame, and an inner cylinder is rotatably connected inside the cylinder. The cylinder and the inner cylinder are rotatably connected via a connecting shaft. A rack is fixedly connected to the outer surface of the inner cylinder, and a gear meshes with the bottom of the rack. Two pairs of telescopic rods movably pass through the inner cylinder and the rack, and a clamping block is fixedly connected to one end of each telescopic rod. When the ultrafiltration membrane fiber needs to be dried, the top of the ultrafiltration membrane fiber is first wound together and tied before being placed inside the inner cylinder. At this time, the telescopic rod drives the clamping block to move inward, thereby clamping and fixing the ultrafiltration membrane fiber. Then, the rotating gear drives the rack and the inner cylinder to rotate at high speed, causing the bottom of the ultrafiltration membrane fiber to move outward due to centrifugal force, facilitating the removal of moisture from the ultrafiltration membrane fiber.

[0004] Although the aforementioned patent can spin dry the moisture on the surface of the ultrafiltration membrane fibers, when drying the ultrafiltration membrane fibers, the inability to rotate the surface of the membrane fibers prevents the hot air from being blown evenly to all parts of the outer surface of the membrane fibers. This results in other outer surfaces of the membrane fibers not receiving hot air drying, further reducing the drying efficiency and effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an ultrafiltration membrane fiber drying device that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: an ultrafiltration membrane fiber drying device, including a drying cylinder, and further including: a mounting cover installed on the top of the drying cylinder, wherein a centrifugal mechanism and a hot air blower are respectively arranged on the top of the mounting cover; wherein the centrifugal mechanism includes a drive shaft that rotates inside the mounting cover through a bearing, a sun gear is fixedly connected to the end of the drive shaft, a planetary gear is meshed with the surface of the sun gear, a clamping member is fixedly connected to the bottom of the planetary gear, and the air outlet of the hot air blower passes through a pipe into the drive shaft.

[0007] Preferably, the clamping member includes a fixing rod fixed to the bottom of the planetary gear, a U-shaped clamping plate connected to the end of the fixing rod, a U-shaped pull rod slidably connected inside the U-shaped clamping plate, and a clamping plate fixedly connected to the end of the U-shaped pull rod.

[0008] Preferably, a rubber pad is fixedly connected to one side of both the clamping plate and the U-shaped clamping plate, and the surface of the rubber pad is provided with anti-slip texture.

[0009] Preferably, a support spring is fitted onto the surface of the U-shaped tie rod, and the end of the support spring is fixedly connected to the clamping plate.

[0010] Preferably, a limiting rod is fixedly connected to the top of the planetary gear, and a limiting groove is formed in the inner top wall of the mounting cover, with the limiting rod sliding on the inner wall of the limiting groove.

[0011] Preferably, the centrifugal mechanism further includes an annular gear ring fixed inside the drying cylinder, and the planetary gear is internally meshed with the annular gear ring.

[0012] Preferably, a drain pipe is fixedly connected to the bottom of the drying cylinder, and a valve is fixedly connected to the surface of the drain pipe.

[0013] Preferably, a servo motor is fixedly connected to the top of the mounting cover, and the servo motor is used to drive the drive shaft to rotate.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] This ultrafiltration membrane fiber drying device, through the cooperation of the drive shaft, sun gear, planetary gear and clamping components, can drive the fixed membrane fibers to rotate on the surface. With this configuration, the centrifugal force of rotation throws out the moisture adhering to the surface of the membrane fibers, and allows hot air to be blown evenly to all parts of the outer surface of the membrane fibers, avoiding the problem of other outer surfaces of the membrane fibers not being dried by hot air, and further improving the drying efficiency and drying effect.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Example 1:

[0025] Reference Figures 1-5An ultrafiltration membrane fiber drying device includes a drying cylinder 1 and a mounting cover 2 installed on the top of the drying cylinder 1. A centrifugal mechanism 3 and a hot air blower 4 are respectively provided on the top of the mounting cover 2. The centrifugal mechanism 3 includes a drive shaft 31 that rotates inside the mounting cover 2 via bearings. A sun gear 32 is fixedly connected to the end of the drive shaft 31. A planet gear 33 is meshed with the surface of the sun gear 32. A clamping member 34 is fixedly connected to the bottom of the planet gear 33. The air outlet of the hot air blower 4 passes through a pipe into the drive shaft 31. A limit rod 331 is fixedly connected to the top of the planet gear 33. A limit groove 21 is opened in the inner top wall of the mounting cover 2. The limit rod 331 slides on the inner wall of the limit groove 21. The centrifugal mechanism 3 also includes an annular gear ring 35 fixed inside the drying cylinder 1. The planet gear 33 is meshed with the annular gear ring 35. A drain pipe 5 is fixedly connected to the bottom of the drying cylinder 1. A valve is fixedly connected to the surface of the drain pipe 5. A servo motor is fixedly connected to the top of the mounting cover 2. The servo motor is used to drive the drive shaft 31 to rotate.

[0026] In this invention, during use, one end of the ultrafiltration membrane fiber is first placed between the clamping members 34 and fixed. Then, the mounting cover 2 is fixed above the drying cylinder 1. Driven by the drive shaft 31, the sun gear 32 rotates. The rotation of the sun gear 32 drives the surface-meshing planetary gears 33 to rotate. Since the clamping members 34 are fixed to the bottom of the planetary gears 33, they rotate synchronously. During the rotation of the clamping members 34, the ultrafiltration membrane fiber is simultaneously rotated, causing the ultrafiltration membrane fiber to move outwards due to the centrifugal force of the rotation, facilitating the removal of moisture from the ultrafiltration membrane fiber. This method improves the drying efficiency of the ultrafiltration membrane fiber surface. Simultaneously, hot air is generated by the hot air blown into the drive shaft 31 through a pipe, and then dries the surface moisture of the membrane fiber inside the drying cylinder 1. The planetary gear 33's top limiting rod 331 slides within the limiting groove 21, guiding and limiting the rotation of the planetary gear 33. Furthermore, the engagement between the planetary gear 33 and the annular gear ring 35 allows the planetary gear 33 to achieve a combined rotation and revolution motion, thereby changing the rotation of the ultrafiltration membrane fiber held by the bottom clamping member 34 of the planetary gear 33 on different surfaces, further improving the drying efficiency of the ultrafiltration membrane fiber.

[0027] With the drain pipe 5 at the bottom of the drying cylinder 1, the water spun out by the ultrafiltration membrane fibers inside the drying cylinder 1 can be discharged in a concentrated manner. With the valve on the surface of the drain pipe 5, the inside of the drain pipe 5 can be controlled to open and close. With the operation of the servo motor, the drive shaft 31 can be driven to rotate.

[0028] As can be added, the servo motor and the drive shaft 31 are rotatably connected via a bevel gear.

[0029] Example 2:

[0030] Reference Figure 2 and Figure 3 Similar to Embodiment 1, but further: the clamping member 34 includes a fixing rod 341 fixed to the bottom of the planetary gear 33, a U-shaped clamping plate 342 connected to the end of the fixing rod 341, a U-shaped pull rod 343 slidably connected inside the U-shaped clamping plate 342, a clamping plate 344 fixedly connected to the end of the U-shaped pull rod 343, a rubber pad 345 fixedly connected to one side of both the clamping plate 344 and the U-shaped clamping plate 342, the surface of the rubber pad 345 is provided with anti-slip texture, a support spring 346 is sleeved on the surface of the U-shaped pull rod 343, and the end of the support spring 346 is fixedly connected to the clamping plate 344.

[0031] With the clamping member 34 in place, one end of the ultrafiltration membrane fiber is placed between the U-shaped clamping plate 342 and the clamping plate 344. Then, the clamping plate 344 can be reset by the U-shaped pull rod 343, thereby bringing the U-shaped clamping plate 342 and the clamping plate 344 closer together, thus clamping the upper two sides of the membrane fiber and fixing the membrane fiber, so that the membrane fiber hangs naturally and prevents knotting during drying. The fixing rod 341 is used to connect and fix the planetary gear 33 to the U-shaped clamping plate 342. With the rubber pad 345, the surface of the clamped membrane fiber can be protected to avoid damage to the membrane fiber caused by metal compression. The anti-slip texture on the surface of the rubber pad 345 can further improve the clamping firmness of the membrane fiber. At the same time, the spring force of the support spring 346 can provide a reaction force to the clamping plate 344, thereby ensuring the clamping force between the U-shaped clamping plate 342 and the clamping plate 344.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
