Abstract
The utility model discloses a full automatic discharging centrifuge control device with a safety protection mechanism. The control device comprises a controller, a vibration intensity scale and a vibration inductor arranged on a centrifuge shell; the output end of the vibration inductor is connected with the input end of the vibration intensity scale; and the output end of the vibration intensity scale is connected with the input end of the controller. After the vibration inductor and the vibration intensity scale are arranged, the vibration intensity scale compares a voltage value sent by the vibration inductor with a preset alarm threshold voltage value and sends the comparative result to the controller; if the controller receives an alarm signal, the controller gives a command to slower the running speed of a rotary drum; after a period of time, if the situation of the over standard of vibration is not improved, the operation of the rotary drum is stopped; and the centrifuge is overhauled, thereby avoiding the occurrence of accidents so that the safety of personnel in the periphery of the centrifuge is reliably guaranteed.
Description
Technical field
The utility model relates to a kind of control device, refers 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.
The utility model content
A technical problem to be solved in the utility model 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 adopted in the utility model 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 beneficial effects of the utility model are: the utility model has 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 utility model;
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 utility model in detail.
As shown in Figure 1 and Figure 2, the control device of full-automatic lower discharging centrifuge described in the utility model, 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 utility model installs 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)
1. the control device of full-automatic lower discharging centrifuge, comprise: controller, it is characterized in that: go back involving vibrations intensity scale and the vibration sensor that is arranged 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.
