[0020] The purpose of the present invention is to provide a semi-automatic pickling device for a tubular furnace to solve the problems existing in the prior art.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The semi-automatic pickling device of the tubular furnace in this embodiment is as follows: Figure 1 As shown, it includes a hanging bracket 1, a first fixed pulley 2, a second fixed pulley 3, a first pull rope 4, a second pull rope 5 and a motor 6. The first fixed pulley 2 and the second fixed pulley 3 are respectively arranged at the two ends of the bottom of the hanging bracket 1. The top end of the first pull rope 4 is connected to the first fixed pulley 2, and the bottom end of the first pull rope 4 is connected to one end of the tubular furnace 11. The top end of the second pull rope 5 is connected to the second fixed pulley 3, and the bottom end of the second pull rope 5 is connected to the other end of the tubular furnace 11. The motor 6 is used to drive the first fixed pulley 2 to rotate.

[0023] In this specific embodiment, a third pull rope 7 is further included. The third pull rope 7 is arranged between the first pull rope 4 and the second pull rope 5. The top end of the third pull rope 7 is connected to the hanger 1, and the bottom end of the third pull rope 7 is connected to the tubular furnace 11.

[0024] In this specific embodiment, two ends of the third pull rope 7 are respectively connected to the rack 1 and the middle of the tube furnace 11 , and the first pull rope 4 and the second pull rope 5 are symmetrically arranged with the third pull rope 7 as the center.

[0025] In this specific embodiment, the motor 6 is fixed on the bracket 1, and the motor 6 is connected to the first fixed pulley 2 via a belt, and the motor 6 drives the first fixed pulley 2 to reciprocate through the transmission of the belt.

[0026] In this specific embodiment, a bearing 8 is fixed in the middle of the tubular furnace 11, and the top of the bearing 8 is connected to the third pull rope 7 through a ball joint. Connecting rings 9 are fixed at both ends of the tubular furnace 11, and the tops of the two connecting rings 9 are connected to the first pull rope 4 and the second pull rope 5 through ball joints. The setting of the bearing 8 and the ball joint allows the tubular furnace 11 to have radial rotation freedom in addition to axial up and down shaking.

[0027] In this specific embodiment, a mounting frame 10 is respectively provided at both ends of the bottom of the hanging frame 1, and the first fixed pulley 2 and the second fixed pulley 3 are respectively installed on the two mounting frames 10 through supporting shafts.

[0028] The working principle of the present invention is as follows:

[0029] The motor 6 drives the first fixed pulley 2 to rotate forward or reversely through a belt drive. The first fixed pulley 2 rotates to pull the first pull rope 4. The first pull rope 4 pulls one end of the tubular furnace 11 to swing up and down, and the second pull rope 5 at the other end will be retracted and extended on the second fixed pulley 3 as the tubular furnace 11 swings. Since each pull rope is connected to the tubular furnace 11 through a ball joint, the tubular furnace 11 can also rotate. The motor 6 drives the tubular furnace 11 to shake the acid liquid inside it, thereby realizing semi-automatic cleaning of the inside of the tubular furnace 11.
