Description

Technical Field

[0001] This utility model relates to a tooling for forming wet activated carbon filter elements. Background Technology

[0002] Wet activated carbon molding is a technology used to manufacture composite activated carbon filter cartridges. This technology involves mixing activated carbon particles, fiber materials and other additives with binders, thoroughly slurrying them in water and stirring them evenly to form a mixed slurry. Then, the mixed slurry is placed on a frame cylinder, and the mixed slurry is adhered to the outside of the frame cylinder by negative pressure adsorption to form a filter material layer. Finally, the molding process is completed through steps such as rolling and drying.

[0003] The wet activated carbon forming fixture typically includes a hollow adsorption shaft that rotates actively and a hollow driven shaft that rotates passively. Both the adsorption and driven shafts are equipped with baffles. Multiple through holes are formed on the surface of the adsorption shaft. Torque is transmitted between the free end of the adsorption shaft and one end of the driven shaft via a conical friction structure. However, when the activated carbon filter element to be processed has a small diameter and a high density of filter material layer, the driven shaft is prone to relative rotation issues when it relies solely on the conical friction structure to follow the rotation. This leads to poor forming quality of the activated carbon filter element, insufficient dimensional accuracy, and poor uniformity of the filter material layer. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wet activated carbon filter element molding fixture with high rotational friction and stable and reliable transmission to ensure the molding quality of the activated carbon filter element.

Then, the conversion joint is connected to the drive shaft tube so that the second retaining member abuts against the other end of the skeleton tube. The driven shaft tube is inserted into the conversion joint along its axial direction. At this time, the annular friction member elastically abuts against the transmission disc.

[0023] See Figures 1 to 3A wet activated carbon filter element forming fixture according to an embodiment of the present invention includes: a drive shaft tube 100, the drive shaft tube 100 having a first channel 110 extending axially inside, and a plurality of through holes 120 communicating with the first channel 110 through the surface of the drive shaft tube 100 along its length direction; a first retaining member 130 fixedly sleeved on the drive shaft tube 100; and a driven shaft tube 200, the driven shaft tube 200 having a second channel 210 extending axially inside, and one end of the driven shaft tube 200 being fixed. A transmission disc 220 is sleeved on the drive shaft tube 100; a conversion joint 300 is detachably connected to the drive shaft tube 100, and a second baffle 310 is provided at one end of the conversion joint 300 near the first baffle 130. The other end of the conversion joint 300 is detachably inserted into the driven shaft tube 200. An annular friction member 400 is provided on the conversion joint 300 to contact the surface of the transmission disc 220. A transfer channel 320 is provided inside the conversion joint 300 to connect the first channel 110 and the second channel 210.

[0024] In the manufacturing of activated carbon filter elements, one end of the skeleton tube is first inserted into the drive shaft tube 100 and abuts against the first baffle 130. Then, the conversion joint 300 is connected to the drive shaft tube 100 so that the second baffle 310 abuts against the other end of the skeleton tube. The skeleton tube is then clamped between the first baffle 130 and the second baffle 310. Under the action of an external telescopic cylinder, the driven shaft tube 200 is inserted into the conversion joint 300 along the axial direction of the driven shaft tube 200. At this time, under the action of axial thrust, the annular friction element 400 elastically abuts against the transmission disc 220. When the drive shaft tube 100 rotates, the friction between the annular friction element 400 and the transmission disc 220 drives the driven shaft tube 200 to rotate. This wet activated carbon filter element forming fixture has large rotational friction and stable and reliable transmission to ensure the forming quality of the activated carbon filter element.

[0025] The first channel 110, the transfer channel 320 and the second channel 210 are connected to connect to an external vacuum device. The mixed slurry is adsorbed onto the outer peripheral wall of the skeleton cylinder under negative pressure to form a filter material layer. After this process is completed, the telescopic cylinder drives the driven shaft tube 200 away from the conversion joint 300 along its axial direction. Then the conversion joint 300 is removed from the drive shaft tube 100, and the skeleton cylinder and the filter material layer can be extracted along the axial direction of the drive shaft tube 100.

[0026] See Figure 2 and Figure 3In some embodiments of this utility model, at least a portion of the transfer channel 320 matches the outer diameter of the drive shaft tube 100. One of the inner peripheral wall of the transfer channel 320 and the outer peripheral wall of the end of the drive shaft tube 100 is provided with a strip-shaped protrusion 330 extending axially parallel to the drive shaft tube 100, and the other is provided with a strip-shaped slot 140 that cooperates with the strip-shaped protrusion 330. The strip-shaped protrusion 330 and the strip-shaped slot 140 are combined to enable the drive shaft tube 100 and the conversion joint 300 to rotate synchronously. The strip-shaped protrusion 330 can separate along the extending direction of the strip-shaped slot 140. Understandably, when the adapter 300 can move axially along the drive shaft tube 100 to engage with the drive shaft tube 100, the strip protrusion 330 extends into the corresponding strip slot 140, thereby transmitting a large torque. When the motor drives the drive shaft tube 100 to rotate, it can also drive the adapter 300 to rotate together. When the adapter 300 moves away from the drive shaft tube 100, the strip protrusion 330 can be directly pulled out from one end of the strip slot 140, making the disassembly and installation between the adapter 300 and the drive shaft tube 100 very convenient, without the need for other fastening structures, which is beneficial to improving production efficiency.

[0027] See Figure 3 In some embodiments of this utility model, in order to improve the reliability and stability of torque transmission between the conversion joint 300 and the drive shaft tube 100, multiple strip-shaped slots 140 are circumferentially distributed around the axial direction of the drive shaft tube 100 on the outer peripheral wall of the drive shaft tube 100, and multiple strip-shaped protrusions 330 are formed on the inner peripheral wall of the conversion joint 300 around the axial direction of the transfer channel 320, which helps to increase the magnitude of the transmittable torque.

[0028] See Figure 2 and Figure 3 In some embodiments of this utility model, the strip-shaped slot 140 is arranged radially through the drive shaft tube 100, and the end of the drive shaft tube 100 is provided with a gradually narrowing guide sleeve 150. The end of the strip-shaped slot 140 near the guide sleeve 150 is provided with an inlet / outlet for the strip-shaped protrusion 330 to enter and exit. It is conceivable that, because the guide sleeve 150 gradually narrows towards the end of the drive shaft tube 100, after aligning the strip-shaped protrusion 330 with the strip-shaped slot 140, jamming is less likely to occur when the drive shaft tube 100 is inserted into the transfer channel 320.

[0029] See Figure 1 and Figure 2In some embodiments of this utility model, the transmission disk 220 is annular, and its outer diameter is larger than that of the drive shaft tube 100 and the conversion joint 300. The conversion joint 300 is provided with an annular retaining edge 340 opposite to the transmission disk 220, and the annular friction element 400 is sandwiched between the annular retaining edge 340 and the transmission disk 220. This structure allows for a larger radial dimension of the annular friction element 400, increasing the friction area. Furthermore, the annular friction element 400 is less prone to relative movement after installation, and disassembly and replacement are very convenient.

[0030] In some embodiments of this utility model, the annular friction element 400 is a circular rubber ring. The two side surfaces of the circular rubber ring elastically abut against the annular flange 340 and the transmission disc 220, respectively. The inner circumferential wall of the circular rubber ring is tightly fitted onto the conversion joint 300. It is understood that when the annular friction element 400 is clamped by the annular flange 340 and the transmission disc 220 and undergoes elastic deformation, both side surfaces of the circular rubber ring are subjected to significant abutment pressure, thereby helping to generate greater static friction and reducing the possibility of relative rotation between the conversion joint 300 and the driven shaft tube 200.

[0031] See Figure 2 and Figure 3 In some embodiments of this utility model, the end of the adapter 300 away from the second retaining member 310 is provided with a plug tube portion 350. The outer peripheral wall of the plug tube portion 350 is frustoconical, and the smaller end of the outer peripheral wall of the plug tube portion 350 is located at the end of the plug tube portion 350. The interior of one end of the driven shaft tube 200 is provided with a frustoconical mating groove 230 that is in complete contact with the outer peripheral wall of the plug tube portion 350. It can be understood that, under the premise of using the friction force between the annular friction member 400 and the transmission disk 220 to drive the driven shaft tube 200 to rotate, the static friction force of the frustoconical plug tube portion 350 in contact with the frustoconical mating groove 230 is used to increase the torque that can be transmitted between the adapter 300 and the driven shaft tube 200, further preventing the adapter 300 and the driven shaft tube 200 from rotating relative to each other.

[0032] See Figure 2 In some embodiments of this utility model, in order to facilitate the installation of the first retaining member 130 and the adjustment of the position of the first retaining member 130 on the drive shaft tube 100, the first retaining member 130 includes a first sleeve 131 and a first disc portion 132 protruding from the outer periphery of the first sleeve 131. The first sleeve 131 is provided with a plurality of circumferentially distributed first threaded holes 133 along its radial direction. Fastening screws are connected to the first threaded holes 133 to press against the outer peripheral wall of the drive shaft tube 100.

[0033] See Figure 2 In some embodiments of this utility model, in order to facilitate the installation of the second retaining member 310, the transmission disc 220 includes a second sleeve sleeved on the driven shaft tube 200. The second sleeve has a plurality of circumferentially distributed second threaded holes 221 through it in the radial direction. The fastening screw is connected to the second threaded holes 221 to press against the outer peripheral wall of the driven shaft tube 200.

[0034] See Figure 1 In some embodiments of this utility model, the surface of the drive shaft tube 100 is provided with multiple sets of vent holes circumferentially distributed around its axial direction. Multiple through holes 120 spaced apart along the length of the drive shaft tube 100 form a group of vent holes. The through holes 120 of adjacent vent hole groups are staggered along the length of the drive shaft tube 100. It is understood that the above-distributed through holes 120 ensures that all positions of the drive shaft tube 100 receive uniform adsorption force, thereby contributing to a more uniform adsorption of the mixed slurry onto the outer peripheral wall of the skeleton cylinder.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
