The utility model provides a tubular evaporator, which relates to the technical field of evaporators and comprises an outer cylinder, an upper spraying cavity is arranged on the upper portion of the outer cylinder, a lower cavity is arranged on the lower portion of the outer cylinder, an evaporation chamber is arranged between the upper spraying cavity and heat exchange tubes, and a plurality of groups of heat exchange tubes are sleeved in the evaporation chamber. The upper end and the lower end of the heat exchange pipe are arranged in the set of positioning clamping pieces in a sleeved mode respectively, the upper end of the heat exchange pipe is led into the upper spraying cavity, the lower end of the heat exchange pipe is led into the lower cavity, the middle of the outer barrel is sleeved with a middle fixing sleeve, an outer pipe opening is formed in the middle of the front side of the middle fixing sleeve, and the upper spraying cavity is of a hollow cone structure. A nozzle is arranged at the upper end of the upper spraying cavity, and the heat exchange pipe is of a hollow cylinder structure. The efficiency that materials form film shapes on the inner walls of the heat exchange tubes is improved, film forming is more uniform, the speed of secondary steam is improved, the downward movement starting speed of liquid materials is further improved, and the film forming device is more efficient and practical.

The utility model relates to the technical field of elasticizers, in particular to a smoke suction motor for an elasticizer, which comprises a motor outer box, dismounting and cleaning mechanisms are arranged on the inner wall of a smoke suction cover and the surface of a filter screen plate, a noise reduction mechanism is arranged on the surface of the motor outer box, and a safety and stability mechanism is arranged in a mounting frame plate. According to the utility model, the phenomenon of potential safety hazards caused by falling of the smoke suction motor in the use process is avoided, so that when the smoke suction motor is used, a user can conveniently pull out the filter screen plate from the interior of the smoke suction cover to clean the surface of the filter screen plate; the phenomenon that the surface of the filter screen plate is blocked in the using process of the smoke suction motor is avoided, the interior of the motor outer box can be silenced when the smoke suction motor is used, the interior of the motor outer box achieves a better noise reduction and silencing effect, and the smoke suction motor is more practical.
