[0005] The technical solution solved is that a vertical center shaft is provided, the lower end of the center shaft is fixed with a horizontal disc, a plurality of worm and gear mechanisms are installed around the disc, the worm is rotatably installed on the lower side of the disc, the worm wheel is on the upper side of the worm, and the worm wheel is hinged to the outer edge of the disc; a small gear is fixed to one end of each worm near the center of the disc, a large gear that can be actively rotated is arranged below the disc, the large gear can drive the plurality of small gears to rotate, and in turn drive the plurality of worm wheels to rotate simultaneously through the worm; a plurality of wiping units are arranged around the lower end of the center shaft, the plurality of wiping units correspond to the plurality of worm wheels one by one, and the rotation of the worm wheels can drive the plurality of wiping units to oscillate with the worm wheels;

[0006] The wiping unit comprises a mounting bracket, one end of the mounting bracket near the center shaft is fixed with the worm wheel, two pulleys are arranged on the mounting bracket, the two pulleys are connected by a conveyor belt, and a water-absorbing sponge layer is attached to the outer side of the conveyor belt; a roller is installed at one end of the mounting bracket near the center shaft, and the roller and the pulley at one end near the center shaft extrude the water-absorbing sponge layer therebetween.

[0007] Further, a protrusion is arranged at the edge of the outer side of the conveyor belt to form a groove, and the water-absorbing sponge layer is attached to the groove.

[0008] Furthermore, a control motor is connected to the large gear, and the control motor is fixed to the lower end of the disc.

[0009] This invention has a clever structure that can wipe away most of the water droplets on the side wall first, and concentrate the majority of the water droplets and let them flow away to the bottom, which greatly reduces the workload of the fan, improves the wiping and drying efficiency, and helps to improve production efficiency.

[0014] Figure 5 This is a diagram of the initial state of this utility model. Detailed Implementation

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 5 The present invention includes a vertical central shaft 1, with a horizontal disc 2 fixed at the lower end of the central shaft 1. Multiple worm gears 3 and worm 4 mechanisms are installed around the disc 2. The worm 4 is rotatably mounted on the lower side of the disc, and the worm gears 3 are located on the upper side of the worm 4 and hinged to the outer edge of the disc. Each worm 4 has a small gear 5 fixed at its end near the center of the disc. Below the disc is a large gear 6 that can rotate actively. The rotation of the large gear 6 drives the multiple small gears 5 to rotate, which in turn drives the multiple worm gears 3 to rotate simultaneously via the worm 4. Multiple wiping units are located around the lower end of the central shaft 1, each wiping unit corresponding to one of the multiple worm gears 3. The rotation of the worm gears 3 drives the multiple wiping units to swing along with the worm gears 3.

[0017] The wiping unit includes a mounting frame 7, one end of which near the central shaft 1 is fixed to a worm gear 3. The mounting frame 7 has two pulleys 8, which are connected by a conveyor belt 9. An absorbent sponge layer 10 is attached to the outer side of the conveyor belt. A roller 11 is mounted on one end of the mounting frame 7 near the central shaft 1. The roller 11 and the pulley 8 near the central shaft 1 press against the absorbent sponge layer 10 between them.

[0018] In order to prevent the side edge of the water absorption sponge layer 10 from being warped, a protrusion is arranged at the outer side edge of the conveying belt to form a groove, and the water absorption sponge layer 10 is attached in the groove.

[0019] The control motor 12 is connected to the large gear 6 and is fixed to the lower end of the disc 2.

[0020] The power motor is connected to the upper end of the central shaft 1 and is installed on the hoisting equipment together with the central shaft 1.

[0021] It is worth noting that, in the present scheme, the central shaft 1 is installed on the hoisting equipment, and in use, the hoisting equipment slowly places the device into the reaction kettle, and the motor is arranged on the hoisting equipment to drive the central shaft 1 to rotate, and the central shaft 1 drives the entire device to rotate, thereby achieving wiping of the inner side wall of the reaction kettle.

[0022] The initial state is shown in Figure 5 The device slowly enters the reaction kettle under the action of the hoisting equipment, and then the motor is started, the control motor 12 drives the plurality of pinions 5 to rotate simultaneously through the large gear 6, the plurality of pinions 5 drive the plurality of worms 4 to rotate downward simultaneously through the plurality of worms 4, the plurality of worms 3 drive the plurality of wiping units to swing downward and expand, and the outermost side of the conveying belt contacts the inner side wall of the reaction kettle, at this time, as shown in Figure 1 、 2 At this time, the central shaft 1 is rotated and slowly lowered by the hoisting equipment, the central shaft 1 drives the plurality of wiping units to rotate, and in the process of rotation, the friction between the conveying belt and the inner side wall of the reaction kettle drives the pulley 8 to rotate, thereby achieving circumferential wiping, and in the process, the entire device is slowly lowered, thereby achieving overall wiping of the reaction kettle; then the control motor 12 is reversed, the plurality of wiping units swing upward and restore to the original state, the hoisting equipment lifts the device, and finally the blower is used for drying, at this time, most of the water has been removed, so the work load of the blower is very small, and the overall wiping and drying efficiency is greatly improved.

[0023] In the above, the water droplets on the inner side wall of the reaction kettle are absorbed by the water absorption sponge layer 10, and then, as the conveying belt rotates, when the water absorption sponge layer 10 reaches the roller 11, the water in the water absorption sponge layer 10 is squeezed out, and since the central shaft 1 is located at the center of the reaction kettle, the squeezed-out water flows directly to the outlet at the bottom of the reaction kettle, which is convenient for discharge and cleaning.

[0024] Since the wiping unit can swing up and down, the device can adapt to reaction kettles of different sizes within a certain range.

[0025] The utility model discloses a clever structure can first wipe the moisture on the side wall, remove most of the water drop, concentrate the most part and flow to the bottom, greatly reduce the working burden of fan, improve the dry efficiency, be favorable to the promotion production efficiency.
