Description
Technical field
The utility model relates to fertilizer production equipment, specifically, relates to a kind of reactor for the production of ureaformaldehyde slow-release or control-release fertilizer.
Background technology
In the production of ureaformaldehyde slow-release or control-release fertilizer, need in reactor heating, make urea and formaldehyde react, generate ureaformaldehyde solution.Existing reactor mostly adopts Steam Heating, owing to not having the retracting device of waste gas, meanwhile, because the boiling point of formaldehyde is lower, is easy to vaporization, and cause the waste of raw material and contaminated environment, the thermal efficiency is lower, energy consumption is high.
Utility model content
The purpose of this utility model is, provides a kind of reactor for the production of ureaformaldehyde slow-release or control-release fertilizer, to solve above-mentioned technical problem.
For solving the problem, the technical scheme that the utility model adopts is:
For the production of a reactor for ureaformaldehyde slow-release or control-release fertilizer, comprise the reaction warehouse being provided with formalin dog-house, urea dog-house and discharging opening, be provided with by motor-driven agitating device in reaction warehouse, the bottom of described reaction warehouse is provided with support; It is characterized in that: be provided with heat exchange jacket in the shell of described reaction warehouse, be provided with the water channel that helical form rises in described heat exchange jacket, bottom and the top of heat exchange jacket are respectively equipped with the heating agent entrance, the heating agent that are connected with water channel and export; Described heating agent outlet connects the entrance of circulating pump by pipeline, described circulation delivery side of pump is by connecting the entrance of instant electric water heater, and the outlet of described instant electric water heater connects heating agent entrance by pipeline; Described agitating device comprises the shaft be in transmission connection with the line shaft of motor and the upper paddle, the lower stirring paddle that are arranged on shaft, and the blade of described upper paddle is contrary with the blade deflection direction of lower stirring paddle; The top of described reaction warehouse is provided with the exhaust outlet with reaction warehouse intracavity inter-connection, and described exhaust outlet connects condensation recovering device by pipeline.
Beneficial effect: compared with prior art, reactor described in the utility model is recyclable formaldehyde vapor in process of production, reduces the pollution to environment in production process, stirs more thoroughly, evenly, raw material availability is high, energy consumption is low in course of reaction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, reactor for the production of ureaformaldehyde slow-release or control-release fertilizer described in the utility model, comprise the reaction warehouse 6 being provided with formalin dog-house 9, urea dog-house 11 and discharging opening 3, be provided with the agitating device driven by motor 10 in reaction warehouse 6, the bottom of described reaction warehouse 6 is provided with support 1.
Be provided with heat exchange jacket 7 in the shell 8 of described reaction warehouse 6, be provided with the water channel that helical form rises in described heat exchange jacket 7, bottom and the top of heat exchange jacket 7 are respectively equipped with the heating agent entrance 17, the heating agent that are connected with water channel and export 14; Described heating agent outlet 14 connects the entrance of circulating pump 15 by pipeline, the outlet of described circulating pump 15 is by connecting the entrance of instant electric water heater 16, and the outlet of described instant electric water heater 16 connects heating agent entrance 17 by pipeline.Described agitating device comprises the shaft 4 be in transmission connection with the line shaft of motor 10 and the upper paddle 5, the lower stirring paddle 2 that are arranged on shaft 4, and the blade of described upper paddle 5 is contrary with the blade deflection direction of lower stirring paddle 2; The top of described reaction warehouse 6 is provided with the exhaust outlet 12 with reaction warehouse 6 intracavity inter-connection, and described exhaust outlet 12 connects condensation recovering device 13 by pipeline.
During work, formalin injects reaction warehouse 6 by formalin dog-house 9, and urea is added in reaction warehouse 6 by urea dog-house 11.Starter motor 10, shaft 4 drives upper paddle 5 and lower stirring paddle 2 to rotate, because the blade deflection direction of upper paddle 5 and lower stirring paddle 2 is contrary, upper paddle 5 promotes materials downward, lower stirring paddle 2 promotes material and moves upward, stir more thoroughly evenly, urea and formalin react; Heating agent enters heat exchange jacket 7 by heating agent entrance 17, and heating agent outlet 14 is controlled in the water channel flowing of being risen by the helical form in heat exchange jacket 7, and heated by the reactant in reactor 6 in the process, reacted material is released by discharging opening 3.The heat transferring medium of discharging from heating agent outlet 14 is sent in instant electric water heater 16 after heating under the effect of circulating pump 15, then sends into heat exchange jacket by heating agent entrance 17.The formaldehyde vapor produced in course of reaction sends into condensation recovering device 13 by exhaust outlet 12 outlet by pipeline, becomes formalin recycling after cooled.
