In the above drawings: 1. a truss; 2. a zinc pot; 3. a closure cap; 4. a sealing plate; 5. a hanger; 31. a strip-shaped opening; 32. a closing door; 33. a recovery pipeline; 41. a plate is embedded.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, the embodiment of the utility model provides a zinc pot flue gas recovery unit is provided, including truss 1 of taking the lifting rope, still include bottom open enclosure 3, slide rail and fix the board 4 of sealing on truss 1's lifting rope, the slide rail sets up in 2 both sides of zinc pot along the 1 moving direction of perpendicular to truss, enclosure 3 bottom is equipped with slide rail complex spout and drive its gliding power device on the slide rail, one of them side of enclosure 3 is connected with recovery tube 33, the one end that enclosure 3 is close to zinc pot 2 is equipped with the closing door 32, the top of enclosure 3 is equipped with the bar mouth 31 that supplies the lifting rope to pass, it is located enclosure 3 top and width and is greater than bar mouth 31 to seal board 4.

Initially the closure 3 is in a position remote from the zinc pot 2, the closure door 32 is opened, the girder 1 with the work pieces reaches above the zinc pot 2 to the position of fig. 3, and the closure 3 is then moved in the direction of the zinc pot 2 and covers over the zinc pot 2, during which the lifting rope passes through the strip-shaped opening 31. After the sealing cover 3 reaches a preset position, the sealing door 32 is closed, the lifting rope is lowered, when the workpieces are completely immersed in the zinc pot 2, the sealing plate 4 seals the strip-shaped opening 31 to form a relatively closed space, and then the workpieces are recovered through the recovery pipeline 33.

An exhaust fan is arranged in the recovery pipeline 33 and provides negative pressure to guide zinc smoke, the exhaust fan is in continuous state, and the other end of the recovery pipe can be connected with a recovery tower or a recovery tank and the like. The zinc fume in the enclosure 3 generally floats upwards, and the sealing requirement on the bottom of the enclosure 3 is not high. The lower lifting rope is that the sealing plate 4 is slightly below after contacting with the top of the sealing cover 3, and the sealing plate 4 is pressed on the strip-shaped opening 31 by the gravity of the product. A better sealing effect is achieved.

Further, the bottom of the sealing plate 4 is provided with an embedded plate 41 with a width smaller than that of the strip-shaped opening 31. The insert plate 41 serves as a guide when it is lowered, ensuring that the sealing plate 4 covers the strip 31. The width of the embedded plate 41 is different from that of the strip-shaped opening 31, so that when the embedded plate 41 is at any position of the strip-shaped opening 31, the sealing plate 4 can seal the strip-shaped opening 31, and the downward placement is performed when the product is stable enough.

Further, the power device is a hydraulic cylinder. The power device can also be realized by the matching of a gear and a rack which are driven by a motor, and the control of the hydraulic cylinder is relatively more stable.

Furthermore, the inner wall of the closed cover 3 is detachably provided with an absorption plate. The zinc cigarette adsorbs easily in the enclosure 3, sets up after absorbing the board, can dismantle after adsorbing more and handle.

Furthermore, a hanging bracket 5 is arranged below the sealing plate 4, a plurality of ropes for binding workpieces are arranged on the hanging bracket 5, and the height of the hanging bracket 5 is lower than that of the top plate of the sealing cover 3. Each truss 1 equipped in the construction of a common factory can only provide two lifting ropes, so that goods can be conveniently lifted from two ends; the hanger 5 can be provided with ropes at a plurality of positions, so that more products can be bound at one time, the binding is more stable, and the falling is not easy. The hanger 5 is lower than the top plate of the closed hood 3, and the closed hood 3 covers the hanger together without influencing the subsequent descending and rising.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
