Abstract
The utility model relates to a temperature control device for a cooling water valve of a freezing dryer, and solves the problem that a water channel valve of a traditional freezing dryer needs to be manually adjusted, and thus inconveniences are brought to an actual production process. The device comprises a freezing dryer body, wherein a cooling box for heat exchange is arranged in the freezing dryer body and provided with a pipeline for water feeding and discharging. The device is characterized in that an electric valve for flow control is arranged on the water feeding and discharging pipeline of the cooling box; a temperature sensor for monitoring evaporating temperature is arranged in the freezing dryer body and connected with a PLC (programmable logic controller) control plate by a signal; the PLC control plate is connected with the electric valve. According to the device, the PLC control plate is adopted for adjusting the flow quantity of the electric valve according to real-time evaporating temperature data, so that the evaporating temperature of the freezing dryer can be more accurately and efficiently controlled.
Description
Technical field
The utility model relates to a kind of cooling driers, particularly a kind of cooling driers cooling water valve attemperating unit.
Background technology
In copper product manufacturing enterprises such as copper bar, copper pipes, in order to guarantee product quality, compressed air conventionally need to be dried and be entered on-the-spot use after dewatering by cooling driers.And for the cooling driers of water-cooled, keep a metastable evaporating temperature extremely important, evaporating temperature need to remain between 0～2 ℃ conventionally, just can possess good drying effect, if evaporating temperature is too high, do not reach dry object, and when evaporating temperature is lower than 0 ℃ of long period, the gas outlet obstruction of can freezing.After traditional cooling driers water channel valve setpoint opening degree, keep stable, water flow is substantially constant, when other parameters such as water flow temperature change, needs manual adjustment, to actual production process, makes troubles.
Summary of the invention
The purpose of this utility model is to need manual adjustment for traditional cooling driers water channel valve, and the problem of making troubles to actual production process provides a kind of cooling driers cooling water valve attemperating unit of automatic control.
The utility model solves the technical scheme that its technical problem adopts: a kind of cooling driers cooling water valve attemperating unit, comprise cooling driers body, in cooling driers body, be provided with the cooler bin for heat exchange, cooler bin has the pipeline of Inlet and outlet water, the pipeline of cooler bin Inlet and outlet water is provided with the electrically operated valve of controlling flow, in cooling driers body, be provided with the temperature sensor of monitoring evaporating temperature, described temperature sensor signal connects PLC control panel, and PLC control panel connects electrically operated valve.According to evaporating temperature, control electrically operated valve, then control the Inlet and outlet water flow of cooler bin, too high when evaporating temperature, regulate electrically operated valve augmented flow; When evaporating temperature is low, regulate electrically operated valve to reduce flow, evaporating temperature can be controlled in less scope all the time, with respect to manual adjustments efficiently and accurately more, improved the operating efficiency of cooling driers.
As preferably, described electrically operated valve is arranged on the outlet conduit of cooler bin.
As preferably, described electrically operated valve is manual/auto integral type valve, also has hand switch.
The utility model adopts PLC control panel to come to regulate electrically operated valve flow according to real-time evaporating temperature data, makes cooling driers evaporating temperature control more precise and high efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model.
In figure: 1, cooling driers body, 2, cooler bin, 3, water inlet pipe, 4, outlet pipe, 5, electrically operated valve, 6, PLC control panel, 7, temperature sensor.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of cooling driers cooling water valve attemperating unit, as shown in Figure 1.This device comprises cooling driers body 1, is provided with the temperature sensor 7 of monitoring evaporating temperature in cooling driers body 1.In cooling driers body, be also provided with cooler bin 2, cooler bin has water inlet pipe 3 and outlet pipe 4.The outlet pipe 4 of cooler bin is provided with electrically operated valve 5, and electrically operated valve is manual/auto integral type valve, has hand switch.Temperature sensor 7 signals in cooling driers body 1 are connected to PLC control panel 6, and PLC control panel 6 is opened size according to evaporating temperature signal controlling electrically operated valve 5.
In this example, the evaporating temperature of cooling driers need to be controlled at 0 ℃ of left and right and just can reach the highest drying efficiency.The temperature of cooler bin water inlet can impact evaporating temperature, therefore, when temperature sensor detected temperatures is greater than 0 ℃, by PLC control panel, tunes up electrically operated valve flow; When temperature sensor detected temperatures is less than 0 ℃, by PLC control panel, turn electrically operated valve flow down.
