Problems solved by technology

For those users whose factory building height is insufficient, they can only build new or heighten the factory building, which causes a lot of trouble and economic loss
Moreover, for the construction of factory buildings, the increase in height is not only a proportional increase in construction costs, but high factory buildings need to be windproof and stable, which dramatically increases the construction cost.
Moreover, the slender rodless cylinder is very expensive, and the equipment manufacturing cost and maintenance cost are very high.

Embodiment 1

[0023] Such as figure 2 As shown, the hose cleaning device of the present invention is arranged on the top of the closed circulation spray drying tower 5, and the top of the frame 8 is provided with two tangential master-slave rollers, and the driving roller 12 is driven by the transmission chain 10 The motor 9 drives and rotates, and the driven roller 11 rotates; the roller surfaces of the driving roller 12 and the driven roller 11 are provided with grooves corresponding to the outer diameter of the hose 15, and the rubber hose 15 is clamped between the driving roller 12 and the Between the driven rollers 11, and ensure that the lifting centerline of the hose 15 is consistent with the centerline of the tower body, the central axis of the driven roller 11 is provided with a fine-tuning mechanism, which can adjust the clamping force, and the guide sleeve 7 is arranged on the lower side of the master and slave rollers . The end of the hose 15 is connected with a cleaning head ...

Embodiment 2

[0026] The structure of this embodiment is basically the same as that of Embodiment 1, but the hose 15 is not driven by the master-slave roller, but driven by the movable pulley 14 . Such as image 3 As shown, the sliding block 16 fixed by the central axis of the movable pulley 14 is driven by the motor 17, and moves up and down along the vertical rail 18; this structure does not need to set the master-slave roller, but only needs to set the fixed pulley and 19 pairs of hoses on the top of the tower. 15 for reversing, thereby simplifying the tower top structure. But because one stroke of the movable pulley 14 will result in twice the stroke of the cleaning head 6, the error for the movement will also be multiplied, so the movable pulley 14 needs to achieve more precise stroke control.

Embodiment 3

[0028] Such as Figure 4 As shown, the hoisting mechanism 20 is directly arranged on the top of the drying tower 5 in this embodiment, instead of the fixed pulley mechanism in the first embodiment. The outer circumference of the reel of the hoisting mechanism 20 is provided with a spiral groove, and the hose 15 is wound in the groove; the central axis of the hoisting mechanism 20 is a hollow shaft structure, one side of the shaft end communicates with the external cleaning agent input port, and the other side shaft end passes through The swivel joint 21 communicates with the hose 15; the hoisting mechanism 20 is driven by the motor 9 during operation, and the lifting of the cleaning head 6 is realized through the rotation of the reel. Compared with the structure of Embodiment 1, the structure of this embodiment can simplify the structure of the fixed pulley, but the hose 15 is easy to accumulate and wind on the reel, which affects the stability of the cleaning liquid delivery ...

Abstract

The invention discloses a flexible pipe cleaning device of a spray dryer. The flexible pipe cleaning device is arranged on the top of a spray drying tower. A cleaning pipeline is a flexible pipe. The tail end of the flexible pipe is connected to a cleaning head and enters the center inside a tower body in an overhanging mode. The beginning end of the flexible pipe is connected to a cleaning fluid inlet. The ascending and descending of the flexible pipe are realized through a pipe supply device arranged on the top of the spray drying tower. The ascending and descending central line of the flexible pipe is consistent with the central line of the tower body. According to the flexible pipe cleaning device of the spray dryer, the needed height L2 of equipment on the top of the spray drying tower is only 800mm, so that the height of an existing hard pipe cleaning device is greatly lowered to be just about one tenth that of an original height L1 which is greater than 7m. Therefore, the flexible pipe cleaning device is more adaptive to a plant height, a plant does not need to be transformed or newly built, and construction cost is lowered substantially. The flexible pipe cleaning device of the spray dryer is excellent in cleaning quality and can completely replace the hard pipe cleaning device in the prior art; equipment control is simple and convenient; an expensive rodless cylinder is not needed; equipment cost and maintenance cost are greatly lowered; equipment reliability and safety are both further improved.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a hose cleaning device for a spray dryer. Background technique [0002] The closed cycle spray drying is carried out in a sealed drying tower to prevent the outside air from oxidizing the material, preventing the explosion of organic solvents, and obtaining high-quality products. The volume of the drying tower is huge, and the materials adhered to the tower wall and the wall only rely on vibrator vibration or manual dry sweeping, often the cleaning is not thorough and not clean, especially in the dead corners, there will be some powder accumulation, this part of the powder accumulation During long-term use, it may cause cross-contamination between powders of different brands, or produce burnt powder, which will become darker and black particles will appear when mixed into the product. At the same time, in the process of manual tower cleaning, due to the large amount of ambient ai...
