The specific embodiment is as follows:
the following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1:
a filtering device for a water pipe as shown in fig. 1-3 comprises a filter 1, a PLC controller 2, an inlet pressure transmitter 3 and an outlet pressure transmitter 4.
The filter 1 comprises a shell 1.1, a filter screen 1.2 and a buffer plate 1.3, wherein a water inlet 1.4 and a water outlet 1.5 are respectively arranged at two ends of the shell 1.1.
A filter screen 1.2 is arranged in a shell 1.1 of the filter 1, and the filter screen 1.2 can be arranged vertically to the inner wall of the shell 1.1, as shown in figure 1; the filter screen 1.2 can be obliquely arranged with the inner wall of the shell 1.1, as shown in fig. 2, the filter screen 1.2 is obliquely arranged to be more convenient for collecting and discharging impurities.
A buffer plate 1.3 is arranged between the water inlet 1.4 and the filter screen 1.2, the number of the buffer plates 1.3 can be 1, as shown in figure 1, one side of the buffer plate 1.3 is fixedly connected with the inner wall of the shell 1.1; the number of the buffer plates 1.3 can be 2, as shown in fig. 2, and the two buffer plates 1.3 are fixedly connected with the inner walls of the two opposite sides of the shell 1.1 respectively.
A slag discharging port 1.6 is arranged between the buffer plate 1.3 and the filter screen 1.2 and on the outer wall of the shell 1.1 close to the filter screen 1.2, and the slag discharging port 1.6 is communicated with a slag discharging pipe 6 through an electromagnetic valve 5; an observation port 1.7 is arranged between the buffer plate 1.3 and the filter screen 1.2 and on the outer wall of the shell 1.1 close to the filter screen 1.2, and a sealing cover 7 is arranged on the observation port 1.7.
The water inlet pressure transmitter 3 is arranged on a pipeline communicated with the water inlet 1.4, and the water outlet pressure transmitter 4 is arranged on a pipeline communicated with the water outlet 1.5.
The signal output ends of the water inlet pressure transmitter 3 and the water outlet pressure transmitter 4 are electrically connected with the PLC controller 2; the electromagnetic valve 5 is electrically connected with the PLC controller 2.
Description of use: when the filtering device is used, the water inlet 1.4 and the water outlet 1.5 are respectively communicated with the original pipeline, the pipeline communicated with the water inlet 1.4 is provided with the water inlet pressure transmitter 3, and the pipeline communicated with the water outlet 1.5 is provided with the water outlet pressure transmitter 4. After a critical water inlet and outlet pressure difference is preset in the PLC 2, the device starts to work.
After the filtered water enters the filter 1, the flow speed of the light product impurities is reduced under the blocking effect of the buffer plate 1.3, the light product impurities gradually gather near the filter screen 1.2, and the filtered water flows out of the water outlet 1.5 through the filter screen 1.2. Meanwhile, the water inlet pressure transmitter 3 and the water outlet pressure transmitter 4 monitor the water inlet pressure and the water outlet pressure and transmit the monitored pressure values to the PLC controller 2, and the PLC controller 2 judges the difference value between the water inlet pressure and the water outlet.
When the PLC monitors that the difference between the water inlet pressure and the water outlet pressure is smaller than the preset critical water inlet pressure and outlet pressure difference, the water outlet pressure is normal, impurities in the shell 1.1 are fewer, and slag discharge is not needed. When the PLC controller monitors that the difference between the water inlet pressure and the water outlet pressure is larger than the preset critical water inlet pressure and outlet pressure difference, the water outlet pressure is reduced, impurities in the shell 1.1 are excessively accumulated, slag discharge is needed, at the moment, the PLC controller 2 controls the electromagnetic valve 5 to be opened, and slag discharge is carried out through the slag discharge port 1.6. When the slag is discharged so that the water inlet and outlet pressure difference is smaller than the critical water inlet and outlet pressure difference again, the PLC controller 2 controls the electric valve to be closed, and slag discharge is stopped.
The sealing cover 7 can be opened, and the foreign matter in the filter 1, the filter screen 1.2, and the buffer plate 1.3 can be inspected through the observation port 1.7.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
