The working principle and the using process of the invention are as follows:
when the explosion-proof and anti-freezing filter is used, a liquid inlet pipeline 120 is communicated with a liquid outlet connecting pipe 130 through a water liquid pipeline, the filtering cylinder 100 is arranged in a vertical upward direction, water liquid is guided into the connecting pipe 110 through the liquid inlet pipeline 120 to enter the filtering cylinder 100, and is filtered by a filter element 400 and then guided out through the liquid outlet connecting pipe 130 and a liquid outlet 131;
in the daily water hammer impact action, most of water hammer impact kinetic energy of the water hammer impact action along the liquid inlet pipeline 120 directly enters the communicating vessel 220 linearly arranged with the liquid inlet pipeline 120, the motion plug head 215 is pushed to slide downwards in the piston guide cylinder 212 through pressure change, the bottom surface elastic part is compressed by driving the connecting pipe sleeve 214 and the guide ring seat 213, the spring is restored after the water hammer is dissipated, and the motion plug head 215 is slowly restored to respond to the next water hammer impact under the surface damping influence of the guide ring seat 213, the connecting pipe sleeve 214 and the connecting rod 232; when the impact of the water hammer is large, the violent impact directly acts on the moving plug 215, the guide ring seat 213 below the connecting sleeve 214 drives the connecting rod 232 to move downwards and compress the elastic part through the instantaneous increase of the static friction with the connecting rod 232, the connecting rod 232 and the blocking head 231 retract to open the pressure relief end 221, part of the liquid flow entering the communicating vessel 220 is discharged, the water hammer effect is slowed or eliminated, the secondary impact on the filtering component caused by the return of the water hammer is avoided, the water liquid passes through the filter element 400 after entering the filtering cylinder 100, impurities in the water liquid are filtered and intercepted by the filter element 400, the filtered water liquid is discharged through the liquid outlet connecting pipe 130, and the filter brush mechanism does not participate in the work;
in the non-working stage, the hydraulic pressure difference between the water inside the duplex pipe 110 and the water outside the filter element 400 is zero, after the water is sensed by the pressure difference sensor 140, an electric signal is sent by the pressure difference sensor 140 to control the starting of the filter brush mechanism 300, the driving motor 310 drives the conical head guide rod 330 to actively stir accumulated liquid inside the filter cylinder body 100, icing is avoided through continuous movement, and the inner wall of the filter element 400 can be scrubbed through the rotation of the conical head guide rod 330 in daily filtering work, so that the anti-blocking operation of the filter element 400 is avoided.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
