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 belongs to the technical field of bag type filtration, and discloses a bag type air filtration device which comprises a mounting frame, middle sleeves are distributed in the mounting frame at equal intervals, filter bag assemblies are fixedly arranged in the mounting frame, and the filter bag assemblies and the middle sleeves are alternately distributed. Through the composite rotating assemblies alternately distributed between the adjacent filter bag assemblies, the disturbance frame rotates in a reciprocating mode between the filter bag bodies on the two sides and impacts and pushes the filter bag bodies on the two sides, on one hand, the filter bag bodies are continuously impacted and shaken in the filtering process, and the internal dust separation effect is improved; on the other hand, expansion contact of the filter bag bodies on the two sides in a high-speed ventilation filtering state is avoided, the filtering area is increased, the filtering area of the filter bag bodies is reduced under the condition that contact accumulation is avoided, the filtering effect of the actual filter bag is greatly enhanced, and the influence of internal blockage and external overlapping is reduced; the use effect is good.

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).

The invention discloses a multi-head feeding quick-opening pull plate filter press which comprises a left main beam assembly, a right main beam assembly, two end main beam supports and a middle thrust plate, and the left main beam assembly, the right main beam assembly, the two end main beam supports and the middle thrust plate are connected through bolts to form an integral frame. A pressing plate assembly, a diaphragm filter plate assembly and a filter plate liquid receiving tank are arranged on the left and right main beam assemblies, an oil cylinder seat assembly is arranged between the left and right main beam assemblies, a hydraulic station assembly is connected to the oil cylinder seat assembly, and the oil cylinder seat assembly is connected with an oil cylinder seat connecting pull plate through a bolt and penetrates through the left and right main beam assemblies in a sleeving manner; by arranging left and right main beam assemblies, end main beam supports, a middle thrust plate, a pressing plate assembly, a diaphragm filter plate assembly, an oil cylinder seat assembly, an oil cylinder seat connecting pull plate and an oil cylinder seat driving system, the two left and right main beam assemblies, the two end main beam supports and the middle thrust plate are connected through bolts to form an overall frame, and the overall supporting and mounting effect is achieved.
