Further, a drain port is arranged on the pulp return main valve, and the pulp passing through the pulp return main pipe can be discharged through the drain port and does not flow back into the first pulp tank or the second pulp tank. Part of the paper pulp without recycling value can be discharged through a drain; and the arrangement of the evacuation port is convenient for overhaul and maintenance.

As an improvement, a pulp mixing pipe is further connected between the first pulp tank and the second pulp tank, a fifth control valve is arranged on the pulp mixing pipe, and the fifth control valve is used for controlling whether the first pulp tank is communicated with the second pulp tank or not. The first pulp tank and the second pulp tank can be used as a large pulp tank when being communicated, and the first pulp tank and the second pulp tank can still be independently used when not being communicated.

Preferably, the first control valve, the second control valve, the third control valve, the fourth control valve, the fifth control valve, the slurry inlet main valve and the slurry return main valve are all solenoid valves, and can be automatically controlled remotely. The intelligent and automatic degree of the system is improved, and the workload of workers is reduced.

Compared with the prior art, the utility model has the advantages of: the setting in two pulp ponds in this scheme mainly has two effects: 1. the mould press can be conveniently connected with any pulp tank at any time, and can be switched between two types of pulp at will without stopping the machine for cleaning; 2. the two paper pulp tanks can be used for paper pulp or ingredients of different types and are simultaneously communicated with the molding press, and then the flow is controlled by the opening size of the control valve to carry out molding pulp preparation, so that the paper support of a specific type is formed, and the applicability of equipment is improved.
