Abstract
The invention discloses a device for controlling the temperature of urea melting heat conducting oil of ureabased compound fertilizer, comprising a urea melting slot as well as a stirring pump, a urine pump and a digital display temperature control instrument which are all arranged on the urea melting slot, wherein the urea melting slot is also connected with an electric adjusting valve and a heat-insulating oil furnace. The device for controlling the temperature of urea melting heat conducting oil of ureabased compound fertilizer has the following advantages that: by adopting the device, heat-insulating oil can be used as a heat resource to replace steam; meanwhile, the temperature of urine is controlled between 122 DEG C and 130 DEG C, the urine can be automatically returned to the heat-insulating oil furnace to be heated for reusing when the temperature of the heat-insulating oil is lower than 122 DEG C so as to save the energy resource and avoid the environment from adverse effects; in addition, the equipment investment is only less than 2 percent of the total investment, thereby reducing the production cost of enterprises.
Description
Technical field
The present invention relates to a kind of device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer, be used for belonging to chemical machinery field with the control of urine temperature within the specific limits.
Background technology
At present, during existing urea-base compound fertilizer is produced, in order to produce the urea-base compound fertilizer of high ammonia; Need to add urea, it is as thermal source urea to be melted with steam that conventional urine melts method, and used steam is normally provided by the boiler of coal-fired or oil, Sweet natural gas; Boiler is a special trade, because the singularity of industry and ratio that investment accounts for equipment funds be more than 5%, and annually all wants the routine inspection of related management department; Operator (kettleman) all need normal annual training before the hilllock; Concerning the enterprise of urea-base compound fertilizer that prepare to produce high ammonia, be a no small cost input, hindered the development of enterprise; And use boiler combustion coal or oil, Sweet natural gas can produce the waste gas waste residue, environment also there is certain disadvantageous effect.
Summary of the invention
The objective of the invention is to address the above problem, a kind of device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer is provided, do not need boiler also can make the control of urine temperature within the specific limits, reduce the production cost that urine melts used thermal source.
Device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer of the present invention comprises that urine melts groove and melts stirring pump, urine pump, the digital display temperature controller on the groove with being located to urinate, and said urine melts groove and also links to each other with heat-conducting oil furnace with motor-driven control valve.
Preferably; This device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer comprises two motor-operated control valves; One end and the urine of one of them motor-driven control valve melt trench bottom and link to each other; One end links to each other with the top of heat-conducting oil furnace, and an end and the urine of another motor-driven control valve melts the groove top and links to each other, and an end links to each other with the bottom of heat-conducting oil furnace.
Device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer of the present invention has following technique effect: owing to adopted this device, can adopt thermal oil to replace steam as thermal source as thermal source, the temperature with urine is controlled between 122 ℃～130 ℃ simultaneously; When the thermal oil temperature is lower than 122 ℃; Can get back in the heat-conducting oil furnace heating automatically and reuse, can save energy, avoid environment to suffer disadvantageous effect; And facility investment only accounts for below 2% of gross investment, reduced the production cost of enterprise.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer of the present invention.
Wherein, 1 for urine melts groove, and 2 for stirring pump, and 3 is the urine pump, and 4 is the digital display temperature controller, and 5 is motor-driven control valve, and 6 is heat-conducting oil furnace.
Embodiment
As shown in Figure 1, device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer of the present invention comprises that urine melts groove 1 and melts stirring pump 2, urine pump 3, the digital display temperature controller 4 on the groove 1 with being located to urinate, and urine melts groove 1 and also links to each other with heat-conducting oil furnace 6 with motor-driven control valve 5.This device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer comprises two motor-operated control valves 5; One end and the urine of one of them motor-driven control valve 5 melts groove 1 bottom and links to each other; One end links to each other with the top of heat-conducting oil furnace 6; One end and the urine of another motor-driven control valve 5 melts groove 1 top and links to each other, and an end links to each other with the bottom of heat-conducting oil furnace 6.
Device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer of the present invention is performed such work:
1) granular urea is melted in the groove 1 by charging opening adding urine,
2) thermal oil in the heat-conducting oil furnace 6 reaches more than 130 ℃ through electrically heated and flows out heat-conducting oil furnace 6 and arrive urine and melt heating urea in groove 1 bottom; When the urine temperature reaches 130 ℃; Motor-driven control valve 5 just cuts out automatically, will strengthen the open degree of thermal oil motor-driven control valve 5 automatically when temperature is lower than 122 ℃; Make the thermal oil that is lower than 122 ℃ get back to heating repeated use in the heat-conducting oil furnace 6 automatically, the urine temperature is normally remained between 122 ℃～130 ℃.
Claims (2)
1. device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer is characterized in that, comprises that urine melts groove and melts stirring pump, urine pump, the digital display temperature controller on the groove with being located to urinate, and said urine melts groove and also links to each other with heat-conducting oil furnace with motor-driven control valve.
2. device for controlling temperature of urea melting heat conducting oil of ureabased compound fertilizer according to claim 1; It is characterized in that; This device comprises two motor-operated control valves, and an end and the urine of one of them motor-driven control valve melt trench bottom and links to each other, and an end links to each other with the top of heat-conducting oil furnace; One end and the urine of another motor-driven control valve melts the groove top and links to each other, and an end links to each other with the bottom of heat-conducting oil furnace.
