Abstract
The utility model discloses a safety alarm system for polyurethane curing agent production. The safety alarm system comprises a support and a reaction vessel installed on the frame, and further comprises a temperature sensor, a single-chip microcomputer, an alarm and a computer. The temperature sensor is arranged in a tank of the reaction vessel, the temperature sensor is connected with the input end of the single-chip microcomputer, the output end of the single-chip microcomputer is connected with the alarm, and the single-chip microcomputer is also connected with the computer. According to the utility model, a temperature in the reaction vessel is measured and acquired through the temperature sensor, acquired data is sent to the single-chip microcomputer, the single-chip microcomputer makes a comparison between a preset value and a sampling value, when the temperature in the reaction vessel is higher or lower than a process set temperature, the single-chip microcomputer controls the alarm to be automatically started and emit an alarm, and at the same time, a measured temperature value is displayed on the display screen of the computer to prompt operators to start a temperature reduction system or a heating system to carry out temperature adjustment on a reaction system so as to ensure safe production.
Description
Technical field
The utility model relates to a kind of security alerting system, more particularly, relates in particular to a kind of polyurethane curing agent production security alerting system.
Background technology
The building-up process of polyurethane curing agent is the process of a heat release, at present, production monitoring is all generally to realize by the temperature of reaction in manual observation reactor, when temperature in the kettle is during higher or lower than technique initialization temperature, rely on artificial unlatching cooling or heating system to carry out temperature adjusting to reaction system, and in production run, need operator to monitor in real time temperature of reaction.This manual supervisory mode of production lacks maneuverability, and to having relatively high expectations of operator, in the time producing polyurethane curing agent, operator must not leave reactor, has caused the waste of manpower.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, a kind of polyurethane curing agent production security alerting system is provided, temperature in monitoring reactor in real time, when temperature in the kettle starts automatically higher or lower than design temperature alarm device, remind operating personnel to operate accordingly.
For achieving the above object, polyurethane curing agent production security alerting system provided by the utility model, comprise support and rack-mount reactor, also comprise temperature sensor, single-chip microcomputer, alarm and computing machine, described temperature sensor is located in the tank body of reactor, temperature sensor is connected with the input end of single-chip microcomputer, and the output terminal of single-chip microcomputer is connected with alarm, and single-chip microcomputer is also connected with computing machine.
The utility model is measured collection by temperature sensor to reactor internal temperature, and the data that collect are sent into single-chip microcomputer, by single-chip microcomputer, setting value and sampled value are compared, when temperature in the kettle is during higher or lower than technique initialization temperature, Single-chip Controlling alarm automatically starts and gives the alarm, on computer screen, show dut temperature value, prompting operating personnel open cooling or heating system is carried out temperature adjusting to reaction system simultaneously, carry out with the safety that ensures production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-support; 2-Weighing module; 3-reactor; 31-hanger; 4-temperature sensor; 5-single-chip microcomputer; 6-alarm; 7-computing machine.
Embodiment
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Consult shown in Fig. 1, a kind of polyurethane curing agent production security alerting system provided by the utility model, comprise support 1 and be arranged on the reactor 3 on support 1, the tank body exterior circumferential of described reactor 3 is laid with multiple hangers 31, reactor 3 is erected on support 1 by hanger 31, between support 1 and hanger 31, be provided with Weighing module 2, Weighing module 2 can accurate-metering polyurethane curing agent synthetic reaction in the weight of each raw material, avoid causing the waste of raw material.
Described security alerting system also comprises temperature sensor 4, single-chip microcomputer 5, alarm 6 and computing machine 7, described temperature sensor 4 is located in the tank body of reactor 3, be used for gathering temperature in the kettle signal, temperature sensor 4 is connected with the input end of single-chip microcomputer 5, the output terminal of single-chip microcomputer 5 is connected with alarm 6, single-chip microcomputer 5 is also connected with computing machine 7, to carry out data communication with computing machine 7.
In process of production, the utility model is measured collection by temperature sensor 4 to reactor 3 internal temperatures, and the data that collect are sent into single-chip microcomputer 5, by single-chip microcomputer 5, setting value and sampled value are compared, when temperature in the kettle is during higher or lower than technique initialization temperature, single-chip microcomputer 5 is controlled alarm 6 and is automatically started and give the alarm, while is in the current temperature of reaction of demonstration screen display of computing machine 7, prompting operating personnel open cooling or heating system is carried out temperature adjusting to reaction system, carry out with the safety that ensures production.
In actual production, many cover security alerting systems can be installed on a computing machine, like this, an operator just can carry out the temperature control of many reactors simultaneously, has improved work efficiency when saving human cost.
