Abstract
The invention discloses a rotating disc receiving tuning fork alarm method and alarm system for preventing wort from leaking. A receiving plate is arranged under the outlet of a sieve plate filter tank. A tuning fork sensor is disposed in the receiving plate and is connected with a PLC through a line. After wort leaks from the outlet and is received by the receiving plate, the horizontally-extending tuning fork of the tuning fork sensor is immersed in the wort and accordingly the vibration frequency of the tuning fork changes. A circuit of the tuning fork sensor detects the frequency change and outputs a digital signal to the PLC. The PLC receives the digital signal and then gives an alarm signal in order to prompt that the outlet leak. The acquisition of the wort leakage signal is implemented through a principle of detecting empty material with the tuning fork, thereby achieving simple and reliable technology.
Description
Technical field
The present invention relates to alarm technique, be specially a kind of rotating disk and connect Lou tuning-fork type anti-wheat juice leakage alarm method and warning system thereof.
Background technology
The wheat juice filter-tank that current China beer industry uses belongs to sieve-board type lautertuns substantially, and this lautertuns has two lees outlets and poor door.
Grain door sealing form is divided into the formula of rotatably compressing and stretching compression type, and these two kinds of seal form all belong to pressing rubber strip sealing in principle.
There is a very large production safety hidden danger in described two kinds of hermetically-sealed constructions, namely in wort filtration process once occur because of poor sealing or other forms of leakage, can cause wheat juice run leak, bring very large economic loss by manufacturing enterprise.
The method stopping the leakage of lautertuns grain door in current production is that human at periodic intervals checks, such a process increases the labour intensity of workman and can not monitor in real time crossing poor door.
Summary of the invention
For the deficiencies in the prior art, technical matters to be solved by this invention proposes a kind of rotating disk carrying out monitoring in real time to connect Lou tuning-fork type anti-wheat juice leakage alarm method and warning system thereof.
The rotating disk that can solve the problems of the technologies described above connects Lou tuning-fork type anti-wheat juice leakage alarm method, arrange to connect drain cap below the poor door of sieve-board type lautertuns, described connecing in drain cap arranges tuning fork sensor, described tuning fork sensor is by connection PLC, when poor door generation wheat juice leaks and by after connecing drain cap splendid attire, tuning fork sensor puts down the tuning fork stretched by the submergence of wheat juice, its vibration frequency changes, this frequency change by sensor self electric circuit inspection out and export an on-off model to PLC, alerting signal is provided after described PLC receiving key amount signal, poor door is pointed out to leak.
The rotating disk that can solve the problems of the technologies described above connects Lou tuning-fork type anti-wheat juice leakage alarm system, comprise connecing drain cap, tuning fork sensor, PLC and alarm with prior art difference, describedly to connect below poor door that drain cap is located at sieve-board type lautertuns and to cover poor door, the tuning fork of described tuning fork sensor is flat to be stretched connecing in drain cap, tuning fork sensor is by connection PLC, and described PLC is by connection alarm.
The described drain cap that connects is arranged on it can be made to rotate to open and close on the rotating mechanism of poor door between horizontal level and upright position.
A kind of simple structure of described rotating mechanism adopts can the pneumatic rotary actuator of stepless change angle, the rotating shaft of described pneumatic rotary actuator be connected to connect drain cap side disk body on.
For reducing to connect the size of drain cap, described poor door and connect between drain cap hopper (closing in for poor door) is set, the suitable for reading of described hopper covers poor door, described in connect the end opening that drain cap covers hopper.
Beneficial effect of the present invention:
In technical solution of the present invention, the collection for wheat juice leakage signal is that the principle utilizing tuning fork to detect material empty realizes, simple, reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the present invention.
Figure number identifies: 1, poor door; 2, drain cap is connect; 3, PLC; 4, tuning fork; 5, alarm; 6, sieve-board type lautertuns; 7, pneumatic rotary actuator; 8, hopper.
Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is described further.
Rotating disk of the present invention connects Lou tuning-fork type anti-wheat juice leakage alarm system, and its technical scheme comprises hopper 8, connects drain cap 2, tuning fork sensor, PLC 3 and alarm 5.
The poor door 1 (diameter is 800mm) covering sieve-board type lautertuns 6 suitable for reading of described hopper 8, the described drain cap 2 (diameter is 500mm) that connects is located at the below of hopper 8 and covers the end opening (diameter is 400mm) of hopper 8, on the horizontal rotating shaft of the disk body connect on the left of drain cap 2 is mounted on (can stepless change angle) pneumatic rotary actuator 7, corresponding to connecing drain cap 2, tuning fork sensor is set, the tuning fork 4 of tuning fork sensor is flat to be stretched connecing in drain cap 2, described tuning fork sensor is by connection PLC 3, described PLC 3 is by connection alarm 5, as shown in Figure 1.
The alarm method that rotating disk of the present invention connects Lou tuning-fork type anti-wheat juice leakage alarm system is:
When wheat juice filters in sieve-board type lautertuns 6, leak when wheat juice occurs poor door 1, the wheat juice leaked is by after connecing drain cap 2 splendid attire, the tuning fork 4 of wheat juice meeting submergence tuning fork sensor, the vibration frequency of tuning fork 4 changes, this frequency change by tuning fork sensor self electric circuit inspection out and export an on-off model to PLC 3, provided report to the police number (taking the mode that lamp dodges or sound rings) by alarm 5 after PLC 3 receiving key amount signal, point out poor door 1 to leak to maintainer.
After wort filtration completes, poor door 1 is opened and is carried out row grain, and before row's grain, connect drain cap 2 and driven by pneumatic rotary actuator 7 and transfer vertical configuration to downwards, to dodge row's grain of poor door 1, row is poor complete, connects drain cap 2 and is driven by pneumatic rotary actuator 7 and upwards go back to as horizontal.
The control of described pneumatic rotary actuator 7 can be incorporated to the working procedure of sieve-board type lautertuns 6, makes to connect drain cap 2 according to the filtration of sieve-board type lautertuns 6 with arrange poor action and automatically close and open hopper 8.
