Description

Technical Field

[0001] This utility model belongs to the field of hollow fiber membrane manufacturing technology, specifically relating to a double cantilever membrane pressing device. Background Technology

[0002] Hollow fiber membranes are fibrous membranes with a self-supporting structure. They are a type of asymmetric membrane, where the dense layer can be located on the outer surface of the fiber (e.g., in reverse osmosis membranes) or on the inner surface (e.g., in microfiltration and ultrafiltration membranes). Hollow fiber membrane production involves preparing the external fiber solution material and the internal core solution material, extruding them, removing the core solution to form a hollow structure, and then performing cleaning, drying, and winding processes.

[0003] However, the existing film pressing equipment uses a single cantilever loading method. When loading the film fibers, the cantilever needs to be lifted to detach it from the equipment before the film fibers can be installed. This is inconvenient to operate and requires a high height for the production line, necessitating a high ceiling or a sunken cleaning section, which is not suitable for existing factory buildings. Utility Model Content

[0004] To overcome the aforementioned shortcomings, the inventors of this utility model, through long-term exploration, experimentation, and continuous reform and innovation, have proposed a double cantilever pressing device. Installed in a water tank, this device reduces the overall height of the cleaning equipment. It eliminates the need for digging a pit in the factory building, minimizing requirements on the factory structure and adapting to different factory environments. The cantilever pressing device compresses the wires from both sides by fixing it in the middle. If the wire bundle breaks, simply raising the cantilever allows the operator to re-pull the wire bundle from both sides, avoiding obstruction when using a fixed pressing device at both ends. Pulling from both ends also reduces the operating span, making traction easier.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A double cantilever pressing device is provided. It includes a mounting column and a pressing cantilever. The mounting column is vertically installed in a cleaning tank. The pressing cantilever is slidably mounted on the mounting column via a lifting mechanism. The pressing cantilever includes a cantilever arm, pressing wheels, and a comb structure. The middle part of the cantilever arm is slidably mounted on the mounting column. Pressing wheels are provided at the lower ends of the left and right sides of the cantilever arm. The yarn bundle passes through the pressing wheels from both sides of the cantilever arm and is pressed and tensioned. A comb structure is provided on the side where the yarn bundle enters the pressing wheel.

[0006] A further preferred embodiment of the double cantilever film pressing device according to the present invention is that the double cantilever film pressing device is installed as a whole in a cleaning tank.

[0007] A further preferred embodiment of the double cantilever pressing device according to the present invention is as follows: the lifting mechanism includes a drive wheel, a driven wheel, a slide rail, and a slider. The drive wheel is provided at the upper end of the mounting column, and the driven wheel is provided at the lower part of the mounting column. The drive wheel and the driven wheel are connected by a chain. The slide rail is provided on the mounting column between the drive wheel and the driven wheel. The slider is located on the slide rail and is fixed to the chain.

[0008] A further preferred embodiment of the double cantilever pressing device according to the present invention is as follows: the mounting column is in the shape of a groove, and lips are provided on both sides of the upper edge of the groove, and the chain is disposed in the groove.

[0009] A further preferred technical solution of the double cantilever pressing device according to the present invention is: a chain limiting block is set in the groove, the limiting block has two rows of grooves corresponding to the chain links, and the groove has a protrusion that cooperates with the groove of the chain itself to limit the position.

[0010] A further preferred technical solution of the double cantilever pressing device according to the present invention is: multiple sets of auxiliary wheels are set on the slider, and each set of auxiliary wheels is clamped on the lip of the side of the mounting column to form a fixed guide.

[0011] A further preferred embodiment of the double cantilever pressing device according to the present invention is: guide wheels are provided on both sides of the slider to contact the sides of the mounting column and maintain the distance between the inner sides of the slider.

[0012] A further preferred embodiment of the double cantilever pressing device according to the present invention is that the cantilever is composed of two single cantilevers, which are respectively fixed on both sides of the slider.

[0013] A further preferred embodiment of the double cantilever pressing device according to the present invention is that the cantilever is provided with triangular reinforcing ribs, and the area where the reinforcing ribs are located is provided with circular hollow holes.

[0014] A further preferred embodiment of the double cantilever pressing device according to the present invention is as follows: the pressing wheel is of the same length as the single cantilever, the pressing wheel is connected to the end of the cantilever by a fixing block at the end of the cantilever, and the other end of the pressing wheel is rotatably mounted on the slider.

[0015] Compared with the prior art, the technical solution of this utility model has the following advantages / benefits:

[0016] 1. The entire cantilever wire pressing device is installed in a water tank, which reduces the overall height of the cleaning equipment. The equipment does not require digging a pit in the factory building, thus minimizing factory requirements and adapting to less demanding environments. When installed in a Class 100,000 cleanroom, the ceiling height in the cleaning equipment area only needs to be 3.5 meters, which is one-third lower than the ceiling height of traditional equipment. This reduces the energy consumption of the cleanroom air conditioning system and the power consumption of the cleanroom air conditioning system during operation, thereby lowering operating costs.

[0017] 2. The cantilever wire pressing device of this utility model can press the wire from both sides by fixing it in the middle. After the wire bundle breaks, the operator only needs to raise the cantilever and pull the wire bundle from both sides again. This avoids the need to lift and detach the whole wire bundle when the wire pressing device is fixed at both ends. Pulling from both ends can also reduce the span of operation and make pulling easier. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the detailed description of the embodiments of this utility model provided below is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0026] Example:

[0027] like Figures 1-4 As shown, a double cantilever film pressing device is disclosed. It includes a mounting column 1 and a pressing cantilever 2. The mounting column 1 is vertically installed in a cleaning tank. The pressing cantilever 2 is slidably mounted on the mounting column 1 via a lifting mechanism 3. The pressing cantilever 2 includes a cantilever 201, a pressing wheel 202, and a comb structure 203. The middle part of the cantilever 201 is slidably mounted on the mounting column 1. The pressing wheel 202 is provided at the lower end of the left and right sides of the cantilever 201. The yarn bundle passes through the pressing wheel 202 from both sides of the cantilever 201 and is pressed and tensioned. The comb structure 203 is provided on the side where the yarn bundle enters the pressing wheel 202.

[0028] The double cantilever film pressing device is installed as a whole in the cleaning tank, and multiple double cantilever film pressing devices are installed in parallel to realize the conveying of the filament bundle.

[0029] The lifting mechanism 3 includes a drive wheel 301, a driven wheel 302, a slide rail 303, and a slider 304. The drive wheel 301 is set at the upper end of the mounting column 1, and the driven wheel 302 is set at the lower part of the mounting column 1. The drive wheel 301 and the driven wheel 302 are connected by a chain 305. The slide rail 303 is set on the mounting column between the drive wheel 301 and the driven wheel 302. The slider 304 is located on the slide rail 303 and is fixed to the chain 305. The movement of the chain 305 drives the slider 304 to move, thereby realizing the raising or lowering of the cantilever 201.

[0030] The mounting post 1 is groove-shaped, with lips 3031 on both sides of the upper edge of the groove. The chain 305 is disposed in the groove, which avoids the chain 305 from contacting other parts during operation, thus creating space for the chain 305 to run. Of course, the mounting post 1 and the guide rail can also be made into the same component to simplify the part structure. The mounting post 1 mainly serves as a mounting support, and its specific structure is not limited.

[0031] A chain 305 limiting block 306 is set in the groove. The limiting block 306 has two rows of grooves corresponding to the chain links. The grooves have protrusions that cooperate with the grooves of the chain 305 itself to limit the position. The limiting block 306 mainly uses the grooves on the side of the chain 305 itself to form corresponding protrusions to limit the position.

[0032] Multiple sets of auxiliary wheels 307 are provided on the slider 304, and each set of auxiliary wheels 307 is clamped on the lip 3031 on the side of the mounting column 1 to form a fixed guide.

[0033] The slider 304 is provided with guide wheels 308 on both sides, which contact the sides of the mounting column 1 to maintain the distance between the inner sides of the slider 304. The auxiliary wheel 307 and the guide wheel 308 are used to avoid direct friction contact between the slider 304 and the guide rail, ensuring smooth movement. Of course, the auxiliary wheel 307 group for the movement of the slider 304 can be set to other similar structures. This embodiment only shows one structure.

[0034] The cantilever 201 is composed of two single cantilever 204s, which are respectively fixed on the two sides of the slider 304. Of course, the cantilever can also be an integral structure, with the middle fixed on the slider 304. The specific form is not limited. The two single cantilever 204s can be replaced individually, which has the advantage of being easy to maintain.

[0035] The cantilever 201 is provided with triangular reinforcing ribs, and circular hollow holes are provided in the area where the reinforcing ribs are located. The reinforcing ribs can increase stability and strength, and the hollow holes can reduce weight.

[0036] The pressing wheel 202 is the same length as the single cantilever 204. The pressing wheel 202 is connected to the end of the cantilever 201 through a fixing block 205. The other end of the pressing wheel 202 is rotatably mounted on the slider 304. Of course, the connection structure of the other end of the pressing wheel 202 can be set according to the requirements. For example, if the cantilever 201 adopts an integral structure, a mounting seat can be set in the middle.
