Description

Technical Field

[0001] The utility model mainly relates to the technical field of nano-powder processing, and particularly relates to a nano-level powder feeding device. Background Art

[0002] Currently, in the preparation process of nano-level powder, it is often necessary to introduce carbon dioxide into the suspension for carbonization.

[0003] According to a feeding device for nano-active calcium carbonate provided in the patent document with the application number CN202022689550.2, this feeding device for nano-active calcium carbonate includes a carbonization tank. A carbonization chamber is provided inside the carbonization tank. One side of the top end of the inner wall of the carbonization chamber is fixedly inserted and connected with a feed pipe. The other side of the top end of the inner wall of the carbonization chamber is provided with a movable hole. The inner wall of the movable hole is movably inserted and connected with an air inlet pipe. The middle part of the bottom end of the inner wall of the carbonization chamber is fixedly inserted and connected with a discharge pipe. A handle is fixedly connected to the outer wall of the air inlet pipe. One end of the handle is sleeved with a rubber sleeve. A fixing mechanism is arranged at the top of the outer wall of the air inlet pipe. The utility model utilizes the settings of the movable hole, the air inlet pipe and the handle. By driving the air inlet pipe to move up and down through the handle, the air inlet pipe can move up and down in the carbonization chamber, so that the carbon dioxide conveyed by the air inlet pipe can reach any height in the carbonization chamber, thereby increasing the contact area between carbon dioxide and the sodium hydroxide suspension and improving the preparation efficiency of nano-active calcium carbonate.

[0004] In the traditional nano-level powder feeding device, by moving the handle to adjust the position of the air inlet pipe, in this way, when adjusting the position of the air inlet pipe, the accuracy is limited, and it is difficult to accurately grasp the length of the air inlet pipe extending into the processing box. Summary of the Utility Model

[0005] The utility model mainly provides a nano-level powder feeding device to solve the technical problems raised in the above background art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0007] A nano-level powder feeding device includes a processing box. One end of the top of the processing box is connected with a feed pipe, and the other end of the top of the processing box is connected with an air intake mechanism;

[0008] The air intake mechanism includes an air inlet pipe inserted through the top end of the processing box, a hose connected to the top end of the air inlet pipe, and a lifting assembly connected to the air inlet pipe;

[0009] The lifting assembly includes two lifting blocks connected to the outer surface of the intake pipe, and a lead screw passing through the housing of the lifting block. The lead screw is connected to the lifting block through a nut. The bottom end of the lead screw is rotatably connected to the top end of the processing box, and the two lead screws are connected through a linkage component.

[0010] Further, the linkage component includes a pulley connected to the outer surface of the bottom end of the lead screw, and a toothed belt connecting the two pulleys. The pulley is rotatably connected to the processing box through a rotating shaft.

[0011] Further, the linkage component further includes a tension pulley rotatably connected to the top end of the processing box, and the tension pulley abuts against the toothed belt.

[0012] Further, a bracket is connected to the upper surface of the processing box, and a motor is connected to the top end of the bracket. The output shaft of the motor is connected to the top end of the adjacent lead screw.

[0013] Further, an encoder is connected to the top end of the motor.

[0014] Further, a through hole for the intake pipe to pass through is provided at the top end of the processing box, and a sealing ring is embedded in the hole body of the through hole.

[0015] Further, the two lead screws have the same helix direction.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, the motor drives the lead screw connected thereto to rotate. When one lead screw rotates, the pulley on it is driven by the lead screw. When the two pulleys rotate, the two lead screws operate synchronously. Since the lead screw is connected to the lifting block through a nut, the lifting block is driven to lift linearly, and the intake pipe is driven by the lifting block, so that the intake pipe can be quickly positioned and lifted in the processing box to adjust the intake position of the processing box.
