Paper mill paper pulp pulping equipment and electrical control system thereof

Abstract

The invention discloses paper mill paper pulp pulping equipment which comprises a bottom plate; a supporting plate a and a supporting plate b which are symmetrically arranged are fixedly arranged at the top of the bottom plate, a pulping tank is connected to the supporting plate a through a shaft, and the other end of the pulping tank is erected on the supporting plate b; the interior of the pulping tank is divided into a first-stage pulping cavity and a second-stage pulping cavity through a partition plate driven by a driver electrically connected with a controller, a stirrer driven by a motor a is arranged on the inner wall of the first-stage pulping cavity, and a shearing device driven by a motor b is arranged in the second-stage pulping cavity; a feeding hopper communicated with the pulping tank is arranged at the position, located at the first-stage pulping cavity, of the top of the pulping tank, a discharging pipe provided with an electromagnetic valve b and communicated with the pulping tank is arranged at the position, located at one end of the second-stage pulping cavity, of the pulping tank, a lifting mechanism driven by the controller is arranged at the other end of the pulping tank, and cleaning assemblies are arranged on the two sides of the pulping tank; and a timer a and a timer b which are electrically connected with the controller are mounted on the bottom plate. The equipment is convenient to operate and uniform in pulping.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment in a paper mill, in particular to pulping equipment in a paper mill and an electrical control system thereof. Background technique [0002] Pulp is a fibrous substance made from plant fibers through different processing methods. According to the processing method, it can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp; it can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. according to the fiber raw materials used. According to different purity, it can be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc. Generally, it is mostly used to make paper and cardboard. The existing pulping equipment used in paper mills has the disadvantages of uneven pulping, slow pulping, and cumbersome operations. It cannot realize automatic operation and is inconven...
