[0002] The filter press is a kind of intermittent operation pressurized filter equipment with multiple filter chambers. The automatic filter press is a kind of filter press with machine, electricity and liquid integration and PLC intelligent control. The high-efficiency automatic filter press is a kind of automatic filter press capable of shortening the intermittent time (shortening the empty running time of the plate pulling trolley return) and continuously circulating (non-returning) plate pulling and cake unloading. The high-efficiency automatic filter press is mainly composed of a double-beam frame, a filter plate pressing mechanism, a multiple filter chamber filtering mechanism, a plate pulling and cake unloading mechanism, a filter cloth cleaning mechanism, a liquid receiving and plate turning mechanism and a PLC program control system. The high-efficiency automatic filter press is suitable for solid-liquid separation of various suspensions.

[0003] The plate pulling and cake unloading mechanism, i.e. the mechanism for continuously pulling open the filter plate and unloading the cake and pulling together the filter plate after unloading the cake, is mainly composed of a driving motor, a chain transmission device, a multiple plate pulling manipulator, a filter plate handle rod and an unhooking pressure roller. The chain transmission device includes a driving short chain, a transmission chain, a driving sprocket, a driven sprocket and a chain bracket.

The plate pulling and cake unloading mechanism has the function of continuously and automatically pulling open the filter plate and unloading the cake and pulling together the filter plate (commonly known as empty plate) after unloading the cake, so as to maximize the plate pulling and cake unloading efficiency and minimize the length of the whole machine. If the plate pulling trolley is used to pull together the filter plate after unloading the cake, the filter plate after unloading the cake cannot be pulled together due to collision and rebound, and the space occupied by the filter plate after unloading the cake is relatively large.

The plate pulling hook is installed on the plate pulling bracket by means of the plate pulling hook pin shaft, and the compression spring is installed on the plate pulling bracket and abuts against the plate pulling hook, so as to make the plate pulling hook upwardly inclined and form the plate pulling manipulator. The multiple plate pulling manipulators are installed on one side of the transmission chain by means of the bracket mounting pin shaft instead of the chain pin shaft. Under the driving of the transmission chain, the plate pulling hook is upwardly inclined to pull the plate (hook the filter plate handle rod) by means of the compression spring, and the plate pulling hook is unhooked by means of the unhooking pressure roller, so as to have the function of continuously and automatically pulling open the filter plate and unloading the cake and pulling together the filter plate after unloading the cake.

The driving short chain connects the long shaft intermediate sprocket of the driving sprocket 18 and the speed reducer sprocket. The driven sprocket 19 is installed at the tail end of the frame. The transmission chain 16 is installed on the driving sprocket 18 and the driven sprocket 19. The chain carrier 20 is installed on the outside of the double main beam 21 below the upper transmission chain 16.
