Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon nanotube processing, in particular to a complete set of pickling equipment for carbon nanotube preparation. BACKGROUND

[0002] As a one-dimensional nanometer material, carbon nanotubes are light in weight, with perfect hexagonal structure connection, and have many abnormal mechanical, electrical and chemical properties. In recent years, with the deepening of the research on carbon nanotubes and nanometer materials, the broad application prospect has been constantly shown. Carbon nanotubes, also known as bucky tubes, are one-dimensional quantum materials with special structure (the radial size is nanometer level, the axial size is micrometer level, and the two ends of the tube are basically sealed). Carbon nanotubes are mainly composed of several to dozens of coaxial circular tubes of carbon atoms arranged in a hexagonal shape. According to the different orientations of the carbon hexagon along the axis, it can be divided into three types of sawtooth, armchair and spiral. Among them, the spiral carbon nanotube has chirality, and the sawtooth and armchair carbon nanotubes have no chirality. In the production and processing of carbon nanotubes, a complete set of pickling equipment is needed for pickling processing. Through retrieval, it is found that the existing pickling complete set equipment is typical, such as a complete set of pickling equipment applied to carbon nanotube preparation disclosed in Publication No. CN213255964U, which comprises a pickling tank, an inclined panel is installed on the inner bottom wall of the pickling tank, a fixing frame is installed on the top rear side of the pickling tank, a hoisting mechanism is installed on the top of the fixing frame, and a pickling net box is arranged in the pickling tank. The complete set of pickling equipment applied to carbon nanotube preparation, with the descent of the pickling net box, the bottom of the pickling net box will fall on the inclined panel, so that the pickling net box will be in an inclined state. Its main feature is that after the pickling net box is lifted by the hoisting mechanism, the treated materials in the pickling net box can be taken out more efficiently, so that the pickling and taking out efficiency of the raw materials can be greatly improved.

[0003] In summary, the existing pickling complete set equipment is mostly placed in the pickling liquid by static treatment of the workpiece, which easily affects the pickling quality due to insufficient contact between the pickling liquid and the workpiece. In view of the above problems, the existing equipment needs to be improved. SUMMARY

[0005] To achieve the above purpose, the present application provides the following technical scheme: a complete set of pickling equipment for carbon nanotube preparation, comprising a pickling tank and a sling,

[0007] The top end of the sling is connected with the winding shaft, and the sling is provided with two groups, the sling is connected with the first porous storage cage and the second porous storage cage respectively, and the side wall of the first porous storage cage and the second porous storage cage is connected with a limiting rod, the side wall of the first porous storage cage and the second porous storage cage is provided with a discharging port, and the bottom of the first porous storage cage and the second porous storage cage is connected with a clamping block, and the clamping block is connected in the inside of the supporting base, the bottom of the supporting base is connected with a ball and a second magnet plate, and the bottom of the second magnet plate is connected with a protrusion.

[0008] Preferably, the top of the partition seat is connected with a first magnet block, and the first magnet block is connected with the protrusion, and the first magnet block is magnetically connected with the second magnet plate.

[0009] Preferably, the lifting mechanism is provided with two groups of symmetrical structures, and the lifting mechanism comprises a rotating shaft, a bevel gear transmission structure, a steering rod, a toothed disc, a rack, a lifting frame and a vertical plate, the rotating shaft is connected with the steering rod through the bevel gear transmission structure, the steering rod is connected with the toothed disc, and the toothed disc is provided with the rack on one side.

[0010] Preferably, the rotating shaft and the steering rod are rotatably connected to the vertical plate, and the vertical plate is fixedly connected to the top of the bearing seat.

[0011] Preferably, the toothed disc is engaged with the rack, and the rack is fixedly connected to the lifting frame.

[0012] Preferably, the lifting frame is slidably connected to the side wall of the bearing seat, and the lifting frame is connected with the exhaust fan.

[0013] Preferably, the inside of the rotating cylinder is symmetrically provided with an electric telescopic rod, one end of the electric telescopic rod is connected with a locking block, and the locking block is engaged with the partition seat.

[0014] Preferably, the clamping block is engaged in the clamping groove in the inside of the supporting base, and limiting plates are symmetrically arranged on the two sides of the clamping block, and the limiting plates are fixedly connected with the inner wall of the clamping groove on the supporting base through limiting springs.

[0015] Preferably, the balls are arranged in an annular array on the outside of the second magnet plate, and the balls are in contact with the inner bottom of the acid pickling tank.

[0016] Preferably, the limiting rod is slidably connected inside the second limiting groove, and the second limiting groove is connected to the first limiting groove. At the same time, both the first limiting groove and the second limiting groove are opened on the inner wall of the pickling tank.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the acid washing equipment for preparing carbon nanotubes,

[0018] (1) This invention effectively solves the problem that existing pickling equipment often places the workpiece statically in the pickling solution during the pickling process, which easily affects the pickling quality due to insufficient contact between the pickling solution and the workpiece. The servo motor drives the rotating drum to rotate the support seat and its bottom first and second porous storage cages in the pickling solution and washing solution on both sides of the separator seat. That is, the rotation allows the workpiece to fully contact the pickling solution and washing solution, thereby improving the pickling quality of the workpiece. The pickling and cleaning quality of the workpieces is improved. In addition, the staff can use the servo motor to transfer the workpieces in the first porous storage cage after pickling to the cleaning tank for cleaning. This is more convenient than manual transfer. At the same time, the limiting rod can move along the second limiting groove when the first and second porous storage cages rotate, so as to limit the first and second porous storage cages and prevent them from deflecting accidentally during rotation. The ball can provide auxiliary support and move when the support base drives the first and second porous storage cages to rotate, thereby improving the stability of rotation pickling and cleaning.

[0019] (2) The present invention can effectively solve the problem that most existing pickling equipment is left to air dry naturally after pickling, which has low air drying efficiency and thus affects the production efficiency of the equipment. The dual-axis motor drives the winding shaft to wind up the lifting sling through the transmission rod, so that the first porous storage cage soaked in the pickling solution and the second porous storage cage soaked in the cleaning solution can be lifted away from the pickling solution and the cleaning solution for draining. At the same time, when the transmission rod rotates, it will drive the rotating shaft to rotate through the belt transmission structure. The rotating shaft will drive the steering rod and the toothed disc above it to rotate synchronously through the bevel gear transmission structure at both ends. The rotating toothed disc will push the rack to drive the lifting frame to move down synchronously, so that the exhaust fan can be moved to one side of the first and second porous storage cages that are draining water to help them dry quickly. At the same time, driven by the dual-axis motor, the first and second porous storage cages will rotate above the pickling solution and the cleaning solution, so that the centrifugal force can be used to further accelerate the drying speed and improve the production efficiency of the equipment.

[0020] (3) The present invention can effectively solve the problem that most existing pickling equipment does not have a self-cleaning function and manual cleaning is troublesome by using the electric telescopic rod, locking block and partition seat together. When the inside of the pickling tank needs to be cleaned, the staff can control the electric telescopic rod to push the locking block to engage with the partition seat used to separate the pickling liquid and the cleaning liquid. Then the partition seat can be driven by the dual-axis motor to rotate inside the pickling tank. During the rotation, the partition seat can scrape off the contaminants adhering to the side wall and bottom of the pickling tank. It is more convenient and faster than manual cleaning.
