Description

Technical Field

[0001] This utility model relates to the field of drying device technology, and in particular to a flat film drying device. Background Technology

[0002] After the flat sheet membranes are produced, they need to be cut into two-meter lengths and soaked in clean water to remove some impurities. Then, the membranes are soaked in glycerin to lock in the moisture in the pores and provide some hydration. After soaking in glycerin, the membranes are removed, dried, and several flat sheet membranes are stacked and laid flat, separated by spacers. They are then rolled up by a machine to complete the production of the spiral ultrafiltration membrane. However, currently, when the membranes are placed on the drying device, the two sides of the membranes that are close together tend to stick together, reducing the drying efficiency. Afterward, workers need to tear the sticking parts of the membranes apart, increasing the labor intensity of the workers and reducing the collection efficiency of the membranes. Utility Model Content

[0003] This utility model discloses a flat film drying device, which solves the problem that when the film is being dried, the two sides of the film that are close to each other tend to stick together, which reduces the drying efficiency of the film. Furthermore, it is necessary to tear the film apart where they stick together afterward, which reduces the film collection efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A flat film drying device includes a base, a pole fixed to the top of the base, a rotatable circular shell above the pole, a hollow ring fitted on the outer side of the circular shell, a ventilation pipe connecting the inner wall of the hollow ring and the outer wall of the circular shell, and an air inlet pipe rotatably connected to the axis at the top of the circular shell; a set of bearing cylinders fixed to the outer ring surface of the hollow ring, a set of air outlet pipes fixed to the bottom of the bearing cylinders, circular holes opened on the surface of the air outlet pipes, conduits connecting the set of air outlet pipes, and a connecting pipe connected to the hollow ring connected to one of the air outlet pipes.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After rotating the hollow ring to hang multiple flat diaphragms sequentially on a set of carrier cylinders, a set of air outlet pipes on the carrier cylinders can separate the two adjacent sides of the diaphragms, preventing them from sticking together. Then, the external fan is started to allow air to enter the cylindrical shell through the air inlet pipe, and then the air enters the hollow ring through the ventilation pipe. Subsequently, the air enters the air outlet pipe through the duct. When the air outlet pipe discharges the air through the circular hole, the diaphragms can be quickly dried. This invention can effectively improve the drying efficiency of the diaphragms and prevent the two adjacent sides of the diaphragms from sticking together, thereby improving the collection efficiency after the diaphragms are dried.

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, this utility model provides a flat film drying device, including a base 1, a pole 2 fixed to the top of the base 1, a rotatable circular shell 3 above the pole 2, a hollow ring 4 sleeved on the outer side of the circular shell 3, a ventilation pipe 43 connecting the inner wall of the hollow ring 4 and the outer wall of the circular shell 3, and an air inlet pipe 9 rotatably connected to the axis at the top of the circular shell 3; a set of bearing cylinders 5 fixed to the outer ring surface of the hollow ring 4, a set of air outlet pipes 6 fixed to the bottom of the bearing cylinders 5, a circular hole opened on the surface of the air outlet pipes 6, a conduit 64 connecting the set of air outlet pipes 6, and a connecting pipe 41 connected to the hollow ring 4 on one of the air outlet pipes 6.

[0014] like Figure 1 and Figure 3 As shown, the air outlet pipe 6 includes a main pipe 61, with fixing rings 62 connected to the top and bottom of the main pipe 61 respectively. Short pipes 63 are connected to the opposite sides of the two fixing rings 62 respectively. The upper short pipe 63 is fixed to the bottom of the support cylinder 5. A connecting pipe 41 is fixed to one of the short pipes 63. At least two air outlet pipes 6 are provided at the bottom of the support cylinder 5. The two air outlet pipes 6 are connected by a conduit 64, and one air outlet pipe 6 is connected to the hollow ring 4 through the connecting pipe 41. When air enters the air outlet pipe 6, the round holes on the surface of the air outlet pipe 6 can discharge the air to dry the diaphragm. The fixing rings 62 are hollow, which can better open up the two sides of the diaphragm that are close to each other, preventing the two sides of the diaphragm from sticking together.

[0015] like Figure 1 and Figure 2 As shown, the end of the support cylinder 5 away from the hollow ring 4 is open. A slider 7 is slidably connected inside the support cylinder 5, and a support rod 71 with one end outside the support cylinder 5 is fixed to one side of the slider 7. A magnet 52 is fixed at the bottom of the support cylinder 5 near the open end. The slider 7 is made of steel. When there are many diaphragms, the handle on the support rod 71 can be pulled to make the slider 7 slide and move the support rod 71 outside the support cylinder 5. When the slider 7 comes into contact with the magnet 52, the magnet 52 can attract the slider 7 and prevent the slider 7 from moving randomly. Then, the operator can hang the diaphragm on the support rod 71.

[0016] like Figure 1 and Figure 2 As shown, the bottom of the support rod 71 is connected to a fixed tube 8 located outside the support cylinder 5. The side of the fixed tube 8 near the hollow ring 4 is connected to a horizontally arranged horizontal tube 81. Both the horizontal tube 81 and the fixed tube 8 have through holes on their surfaces. A set of exhaust pipes 42 are fixedly connected to the hollow ring 4 and extend into the inner cavity of the hollow ring 4. The end of the exhaust pipe 42 away from the hollow ring 4 passes through the slider 7 and extends into the support rod 71. The exhaust pipe 42 is slidably connected to the support rod 71. After most of the support rod 71 has moved outside the support cylinder 5, the end of the exhaust pipe 42 away from the hollow ring 4 is still inside the support rod 71. When the air enters the support rod 71 through the exhaust pipe 42, the air can enter the horizontal pipe 81 through the fixed pipe 8, and the air can also be discharged through the perforations on the fixed pipe 8 and the horizontal pipe 81 to facilitate the rapid drying of the diaphragm. The fixed pipe 8 and the horizontal pipe 81 can open up the two sides of the diaphragm that are close to each other. There are at least two horizontal pipes 81, which are distributed vertically. The ends of the two horizontal pipes 81 that are close to the hollow ring 4 are respectively inserted into the inner side of the corresponding two fixed rings 62.

[0017] like Figure 1 and Figure 2 As shown, a first rubber protrusion 51 and a second rubber protrusion 72 are respectively fixed to the surfaces of the bearing cylinder 5 and the bearing rod 71. The arrangement of the first rubber protrusion 51 and the second rubber protrusion 72 can prevent the diaphragm from completely adhering to the surface of the bearing cylinder 5 or the bearing rod 71 when the diaphragm is placed on the bearing cylinder 5 or the bearing rod 71, thereby improving the drying efficiency of the contact area between the diaphragm and the bearing cylinder 5 or the bearing rod 71.

[0018] like Figure 1As shown, a motor 21 is fixed to the top of the upright 2 via a disc. A turntable 22 is fixed to the shaft of the motor 21. A rotating rod 23, which is fixed to the bottom of the circular shell 3, is fixed to the top of the turntable 22. A reinforcing rod 24, which is rotatably connected to the disc at the top of the upright 2, is fixed to the bottom of the turntable 22. After the motor 21 is started, the shaft of the motor 21 can drive the circular shell 3 to rotate via the turntable 22 and the rotating rod 23. The circular shell 3 can then drive the hollow ring 4 to rotate via the ventilation pipe 43, facilitating the loading and unloading of the diaphragm. An annular groove is provided at the top of the upright 2, allowing the reinforcing rod 24 to rotate with the turntable 22 and increasing the stability of the turntable 22.

[0019] In use, after rotating the hollow ring 4 to hang the membranes on a set of carrier cylinders 5 in sequence, the air outlet pipe 6 can open up the two sides of the membranes that are close to each other, preventing the two sides of the membranes from sticking together; then start the external fan (hot air or cold air can be selected according to the actual situation). When the air is discharged through the round hole on the air outlet pipe 6, the membranes can be dried, improving the drying efficiency of the membranes.
