Abstract

The utility model relates to a fertilizer production device, in particular to a urea formaldehyde reactor which comprises a shell and a stirrer mounted in the shell. A urea feeding port is arranged at the upper end of the shell, a urea formaldehyde outlet is arranged at the lower end of the shell, a spiral pipe is arranged on the inner surface of the shell, and a steam inlet and a steam outlet are arranged on the spiral pipe. The urea formaldehyde reactor is characterized in that a formaldehyde feeding port and an exhaust pipe are further arranged on the shell, a driving shaft is mounted at the upper end of the shell through a bearing and is in transmission connection with a driving motor, and stirring blades are fixedly mounted on the driving shaft. The urea formaldehyde reactor can be used for continuous production and is high in production efficiency and fine in product quality.

Description

The urea-formaldehyde reactor

Technical field

The utility model relates to a kind of fertilizer production equipment, is a kind of urea-formaldehyde reactor specifically.

Background technology

In the production of composite fertilizer, need urea and formaldehyde hybrid reaction be generated the ureaformaldehyde intermediate.Owing to be that urea and formaldehyde are not easy to mix fully, need constantly heating aborning, to keep normally carrying out of reaction.Existing urea-formaldehyde reactor does not mostly possess continuous production capacity, and production efficiency is low, influences the raising of product quality.

Summary of the invention

The purpose of the utility model provides the urea-formaldehyde reactor that a kind of mixing effect is good, can produce continuously, help improving the quality of products.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The described urea-formaldehyde reactor of the utility model comprises housing, is installed in the agitator in the housing; The upper end of housing is provided with the urea dog-house; The lower end of housing is provided with the ureaformaldehyde outlet, and the inner surface of housing is provided with spiral coil, and said spiral coil is provided with steam inlet and steam (vapor) outlet; It is characterized in that: also be provided with formaldehyde dog-house and blast pipe on the said housing; Upper end at housing is equipped with driving shaft through bearing, and driving shaft and drive motors are in transmission connection, and is installed with stirrer paddle on the said driving shaft.

After adopting technique scheme, this urea-formaldehyde reactor can be used for continuous production, and production efficiency is high, good product quality.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.

As shown in Figure 1; The described urea-formaldehyde reactor of the utility model comprises housing 1, is installed in the agitator in the housing 1, and the upper end of housing 1 is provided with urea dog-house 4, and the lower end of housing 1 is provided with ureaformaldehyde outlet 5; The inner surface of housing 1 is provided with spiral coil 2; Said spiral coil 2 is provided with steam inlet 10 and steam (vapor) outlet 11, also is provided with formaldehyde dog-house 7 and blast pipe 8 on the said housing 1, through bearing driving shaft 3 is installed in the upper end of housing 1; Driving shaft 3 is in transmission connection with drive motors 12, is installed with stirrer paddle 9 on the said driving shaft 3.

Certainly, subsidiary conduits such as water inlet 12, manhole 13 can also be set on housing 1.Be respectively applied for and in housing 1, add water and overhaul of the equipments.

During use, be connected steam boiler with steam (vapor) outlet 11, to housing 1 heating through steam inlet 10.Drop into urea and formaldehyde in proportion from urea dog-house 4 and formaldehyde dog-house 7, open drive motors 12, urea and formaldehyde are stirred through stirrer paddle 9.Opening ureaformaldehyde outlet 5 after reaction is accomplished gets final product.
