This invention discloses a production process for filter screen manufacturing equipment and the resulting filter screen. The aim is to provide a high-efficiency, precise, and automated production process for filter screen manufacturing equipment and the resulting filter screen. The key technical points include a combination of numerous process flows such as raw material preparation, cutting and shaping, screen frame forming and fabrication, secondary shaping of the screen frame, and assembly. Precise control at each stage significantly improves product quality, production efficiency, and market competitiveness, resulting in good economic and social benefits. This invention applies to the field of filter screen manufacturing equipment technology.

The present application relates to filter press technical field, specifically to a kind of variable attitude filter plate assembly for filter press, including fixed plate, multiple filter plates and connecting unit, multiple the filter plate is arranged in the side of the fixed plate, each the filter plate is respectively through the connecting unit with the fixed plate movable connection, to make each the filter plate can be converted between vertical attitude and inclined attitude relative to the fixed plate;When the driving unit drives each the filter plate mutually away and forms second state, each the filter plate switches to inclined attitude, the spacing between adjacent filter plate increases, and the filter surface of each the filter plate is inclined relative to vertical direction, solved the existing filter press unloading cake because of the strong adhesion between mud cake and filter plate and lead to unloading cake not completely, need manual cleaning problem.

The utility model provides an active ink negative pressure filtering system which comprises a filtering device and a liquid storage tank, the filtering device is communicated with the liquid storage tank, a negative pressure pipe is arranged on the liquid storage tank, the filtering device comprises a funnel, a first supporting screen plate is arranged on the funnel, the first supporting screen plate is of a net structure arranged in a wire coiling mode, and a filtering membrane can be placed on the first supporting screen plate. An electric reciprocating track is arranged on one side of the funnel and extends in the length direction of the first supporting screen plate, an ink spraying pipe is arranged on the electric reciprocating track, a spraying head is arranged at one end of the ink spraying pipe and located over the first supporting screen plate, and the ink outlet end face of the spraying head faces the first supporting screen plate. The other end of the ink spraying pipe is communicated with ink to be filtered, and the ink spraying pipe can move along the electric reciprocating track. The active ink negative pressure filtering system is high in filtering efficiency, easy to operate and high in automation degree.

The invention relates to a filter element (10), in particular an air filter element, comprising a pleated filter media bellows (12) which extends at least partially circumferentially about a longitudinal axis (14), in which pleats (16) of the filter media bellows (12) extend substantially parallel to the longitudinal axis (14). The filter media bellows (12) includes an inner pleat fold (20) at an inner periphery (18) and an outer pleat fold (24) at an outer periphery (22). The at least one inner pleat fold (20) and the at least one outer pleat fold (24) each comprise a pleat locking deformation (26, 28) having an extension length along the longitudinal axis (14) that is less than a total longitudinal extension length (30) of the filter media bellows (12).
