The present invention discloses a method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.

The present invention relates to a brine injection system with a plurality of needles, which are inserted into a product and through which brine is injected into the product, wherein brine which does not end up in the product is collected and recycled and wherein during recycling, the brine flows through a filter.

A suction nozzle for a screen filter has an inlet orifice at its distal side through which liquid is arranged to flow into the nozzle during a cleaning operation. The orifice has a longitudinal extension and a width of the orifice changes along its longitudinal extension.

Provided are a filter cloth recovery device and a copper rod continuous casting and rolling manufacturing system using the same. This device includes a cleaning water tank, a winding mechanism and a cleaning mechanism provided on the cleaning water tank. The winding mechanism includes: a winding shaft provided on the cleaning water tank for winding a filter cloth after being cleaned; a first guiding roller for guiding a filter cloth to be cleaned into a cloth-transmitting path within the cleaning water tank; and a second guiding roller between the first guiding roller and the winding shaft along the cloth-transmitting path for providing a tension force to the filter cloth. One end of the winding shaft is connected with a driving mechanism. The cleaning mechanism is provided with multiple liquid spraying openings for spraying a cleaning fluid to the filter cloth located in the cloth-transmitting path during winding.

The residual brine remaining from a brine injection process is collected and filtered by a primary filter system. Thereafter, the filtered brine is routed to a saddle tank from where the brine is routed, as needed, to a secondary filter remove particulates from the brine sufficient to enable the brine then to be routed to an injection head for reuse for injection into the work product. Clean brine is used to clean the primary and secondary filter systems. Thereafter, the spent brine from cleaning the primary and secondary filters is routed to the primary filter system to undergo primary filtration in the same manner as the brine collected after being expelled by the injection process. After this primary filtration, the brine is routed to the saddle tank.

A control mechanism for self-cleaning filtration systems. One embodiment is a controller for a filtration system that comprises a suction scanner and a screening element having modifiable respective locations therebetween. The controller comprises an input terminal for receiving a relative location signal and additional a differential pressure input terminal. The controller monitors differential pressure and outputs an activation signal after the differential pressure has exceeded a threshold value. The controller outputs a termination signal based on the relative location signal. Another embodiment is a filtration system that comprises: a screening element located within a filtration chamber, and a suction scanner for self-cleaning thereof. A location tracker communicates to a switching mechanism during self-cleaning sessions a signal indicative of a location of the suction scanner with respect to the screening element. The switching mechanism automatically terminates self-cleaning sessions based on the signal.
