Abstract
The invention discloses a control device for a full automatic discharge centrifuge with safety protection device, comprising a controller, a vibration intensity scale and a vibration inductor arranged on the casing of the centrifuge; wherein, the output end of the vibration inductor is connected with the input end of the vibration intensity scale; the output end of the vibration intensity scale is connected with the input end of the controller. As a vibration inductor and a vibration intensity scale are added to the control device, the vibration intensity scale can compare the voltage value from the vibration inductor with the preset alarm threshold voltage value; if the overproof vibration continues after a certain time, the rotating drum is shut down and the centrifuge is overhauled; thus accidents are avoided and the personal safety of the operators around the centrifuge is reliably protected.
Description
Technical field
The present invention relates to a kind of control device, refer more particularly to the control device of full-automatic lower discharging centrifuge.
Background technology
As everyone knows, the situation of present full-automatic lower discharging centrifuge ubiquity vibration exceeding the standard in reinforced process, the reason that causes vibration exceeding the standard has a lot, if due to the material skewness in the rotary drum, rotary drum turns round under the situation of vibration exceeding the standard for a long time so, will quicken the aging of rotary drum, shorten its service life greatly; And if due to the mechanical breakdown of centrifuge, as untimely discovery, close down centrifuge, will lead to major accident, personnel's personal safety around the serious threat centrifuge.
Summary of the invention
A technical problem to be solved by this invention is: a kind of control device with full-automatic lower discharging centrifuge of security protection mechanism is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the control device of full-automatic lower discharging centrifuge, comprise: controller, vibration severity table and be arranged on vibration sensor on the described centrifuge casing, the output of vibration sensor links to each other with the input of vibration severity table, and the output of vibration severity table links to each other with the input of controller.
Described vibration sensor is the magneto-electric vibration sensor.
Described controller is that programmable logic controller (PLC) is PLC.
The invention has the beneficial effects as follows: the present invention has been installed additional after vibration sensor and the vibration severity table, the vibration severity table is compared the magnitude of voltage that vibration sensor sends with default warning threshold voltage value, and the result that will compare gives controller, if what controller was received is alarm signal, then send the slow down running speed of rotary drum of instruction, after a period of time, if the situation of vibration exceeding the standard does not take a turn for the better, then close down the running of rotary drum, then centrifuge is overhauled.So just avoid the generation of accident, made centrifuge personnel's personal safety on every side obtain reliable guarantee.
Description of drawings
Fig. 1 is a theory structure schematic diagram of the present invention;
Fig. 2 is the structural representation that the full-automatic lower discharging centrifuge of magneto-electric vibration sensor is installed;
Among Fig. 1, Fig. 2: 1, casing, 2, rotary drum, 3, the magneto-electric vibration sensor, 4, the vibration severity table, 5, programmable logic controller (PLC).
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1 and Figure 2, the control device of full-automatic lower discharging centrifuge of the present invention, comprise: controller, vibration severity table 4 and be arranged on vibration sensor on the described centrifuge casing 1, the output of vibration sensor links to each other with the input of vibration severity table 4, and the output of vibration severity table 4 links to each other with the input of controller.In the present embodiment, described vibration sensor is a magneto-electric vibration sensor 3, and described controller is that programmable logic controller (PLC) 5 is PLC.
Occur vibration in the centrifuge running, the coil cutting magnetic line of magneto-electric vibration sensor inside can be exported different equivalent voltage signals
The present invention is installed additional after magneto-electric vibration sensor 3 and the vibration severity table 4, when vibration appears in centrifuge in running, magneto-electric vibration sensor 3 Inside coils will cutting magnetic line, thereby the different equivalent voltage signals of output, the magnitude of voltage that vibration severity table 4 sends magneto-electric vibration sensor 3 is made comparisons with the default warning threshold voltage that adapts with vibration class, and the result that will compare gives programmable logic controller (PLC) 5, if what programmable logic controller (PLC) 5 was received is alarm signal, send the slow down running speed of rotary drum 2 of instruction at once, after a period of time, if the situation of vibration exceeding the standard does not take a turn for the better, then close down the running of rotary drum 2, then centrifuge is overhauled.So just avoid the generation of accident, made centrifuge personnel's personal safety on every side obtain reliable guarantee.
Claims (3)
