Hose cleaning device for spray dryer

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 ambie...

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.
