Description
Technical field
The utility model is specifically related to the crystallizer cooling system self-con-tained unit in a kind of maltitol production technology.
Background technology
Crystal maltitol is to take maltose as raw material, and hydrogenation obtains the maltitol of high concentration, then through crystallization, drying, be packaged to be the powdery product that product forms, smell is pure, is widely used in the industries such as food, medicine, chemical industry.Crystallization Procedure is a vital operation during crystal maltitol is produced, and its capital equipment is crystallizer, and crystallizer and plate type heat exchanger are connected to form the material self-loopa by pipeline, and the logical cooling water of plate type heat exchanger makes the material cooling.Its concrete process is as follows:
Material enters crystallizer, by plate type heat exchanger, reduces temperature of charge, makes Material control in crystallization requirement temperature.Crystallizer is provided with temperature inductor and temperature indicator, the crystallization process staff need observe temperature indicator at any time, and manual control panel formula heat exchanger cooling water inflow is controlled temperature of charge and required temperature in crystallization, operates more loaded down with trivial details, and the bad control of temperature of charge, crystallization effect is poor.
The utility model content
The purpose of this utility model is to solve in current maltitol production, in Crystallization Procedure, need to control manually the cooling water inflow of plate type heat exchanger, complex operation, temperature of charge is wayward, the defect that crystallization effect is poor, a kind of automatic operation is provided, without controlling manually, the cooling water inflow precise control of plate type heat exchanger, the crystallizer cooling system self-con-tained unit of raising crystallization effect.
The utility model is achieved by the following technical solution:
It is a kind of crystallizer cooling system self-con-tained unit, comprise crystallizer and plate type heat exchanger, described plate type heat exchanger is connected to form the Matter Transfer loop by feed pipe and discharge pipe and crystallizer, also be provided with cooling water inlet pipe and cooling water outlet pipe on plate type heat exchanger, it is characterized in that described crystallizer is provided with the crystallizer temperature inductor, the cooling water outlet pipe of plate type heat exchanger is provided with the outlet pipe temperature inductor, the cooling water inlet pipe of plate type heat exchanger is provided with pneumatic operated valve, described crystallizer temperature inductor, the outlet pipe temperature inductor, pneumatic operated valve all is connected with control cabinet.
As a limited scheme of the present utility model: control cabinet is PLC control cabinet or Single-chip Controlling case.
As a limited scheme of the present utility model: crystallizer temperature inductor and outlet pipe temperature inductor are thermojunction type temperature inductor or thermistor-type temperature inductor.
The utlity model has that automaticity is high, easy to use, the cooling water inflow is controlled stable advantage.The utility model is integrated the formation control signal by the difference of crystallizer temperature inductor, outlet pipe temperature inductor, control plate type heat exchanger cooling water inlet pipe pneumatic operated valve by control cabinet, realization is regulated the cooling water inflow according to the difference of temperature of charge and cooling water temperature, make temperature of charge in crystallizer be stabilized in best crystallization temperature, improve crystallization effect and the efficiency of crystallizer.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
As shown in the figure: 1 feed pipe; 2 pneumatic operated valves; 3 cooling water inlet pipes; 4 discharge pipes; 5 cooling water outlet pipes; 6 outlet pipe temperature inductors; 7 crystallizer temperature inductors; 8 crystallizers; 9 plate type heat exchangers; 10 control cabinets.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1: 9 of plate type heat exchanger is connected to form the Matter Transfer loop by feed pipe 1 and discharge pipe 4 with crystallizer 8, the cooling water inlet pipe 3 of plate type heat exchanger 9 is provided with pneumatic operated valve 2, cooling water outlet pipe 5 is provided with outlet pipe temperature inductor 6, crystallizer 8 is provided with crystallizer temperature inductor 7, and described outlet pipe temperature inductor 6, crystallizer temperature inductor 7, pneumatic operated valve 2 all are connected with control cabinet 10.
The utility model is integrated the formation control signal by the difference of crystallizer temperature inductor 7, outlet pipe temperature inductor 6, the pneumatic operated valve 2 of controlling on cooling water inlet pipe 3 by control cabinet 10, realization is regulated the cooling water inflow according to the difference of temperature of charge and cooling water temperature, make the interior temperature of charge of crystallizer 8 be stabilized in best crystallization temperature, improve crystallization effect and the efficiency of crystallizer 8.
