Thermal grinding treatment equipment for wood raw materials used in papermaking

Abstract

The invention discloses thermal grinding treatment equipment for wood raw materials for papermaking, which comprises a bottom plate, a refining box is fixedly connected to the right side of the top of the bottom plate, and a connection box is fixedly connected to the top of the refining box, and the refining box The top of the inner wall is fixedly connected with a transmission box. In the present invention, the wood raw material is pushed to the right by the spiral turning mechanism, so that the raw material inside the feeding barrel can be turned up and down, and then the steam generator evenly distributes the raw materials inside the storage box and the raw materials falling into the feeding barrel through the placement box and the ventilation plate. Steam preheating, so that it has the advantages of convenient preheating of wood raw materials and better heating effect of wood raw materials, which solves the problem that the existing thermal grinding treatment equipment usually preheats wood raw materials in fixed containers, or through The helical blade pushes the wood material to move while preheating, which easily leads to the problem of poor heating effect of the wood material at the top or center, and at the same time improves the refining effect to a certain extent.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to thermal grinding treatment equipment for wood raw materials used in papermaking. Background technique [0002] Thermal grinding treatment equipment is also called thermal grinding machine. Thermal grinding machine is widely used in wood treatment. It can extract the fibers in sheet wood to make fiberboard and other boards. Thermal grinding machine is generally used under high temperature and high pressure. In order to obtain the required products, the wood is ground under the environment. During the grinding process, the movable grinding disc and the fixed grinding disc cooperate with each other to grind the input raw materials. [0003] However, when the existing heat grinding treatment equipment steam preheats the wood raw material, it usually preheats the wood raw material in a fixed container, or pushes the wood raw material to move through the spiral blade, but no matter...
