Panel reagent spraying device and return liquid circulating system

Abstract

The invention discloses a return liquid circulating system which comprises a liquid supply tank and a liquid return tank, wherein a liquid return pipe communicating with a liquid outlet of a liquid collecting tank is arranged on the liquid return tank, at least one layer of filter screen for filtering particle impurities is arranged in the liquid return tank, and the filter screen is located belowan outlet of the liquid return pipe; a liquid inlet pipe connected with a spray gun is arranged on the liquid supply tank, and a liquid inlet pump is arranged on the liquid inlet pipe; and the liquidreturn pipe is connected with the liquid supply tank through a liquid return communicating pipe. The invention further discloses a panel reagent spraying device. By arranging the liquid return tank connected with the liquid collecting tank, reagents collected in the liquid collecting tank flow back into the liquid return tank through the liquid return pipe, particle impurities are filtered out through the filter screen arranged in the liquid return tank, then the reagents enter the liquid supply tank through the liquid return communicating pipe, so that cyclic utilization is achieved; The panel reagent spraying device can recover and recycle the reagents.

Description

technical field [0001] The invention belongs to the technical field of plate processing, in particular to a plate chemical spraying device and a liquid return circulation system thereof. Background technique [0002] Among the existing household wooden products, a large number of solid wood particle boards and density boards are used. Solid wood particle board is made of wood or wooden poles, logs are broken, fine wood fiber is used on both sides, and long wood fiber is sandwiched in the middle. After applying adhesive, it is glued together under heat and pressure. The panel finish is melamine finish. Its section presents a honeycomb plate. Density board is called density fiberboard. It is made of wood fiber or other plant fiber, prepared by fiber, applied with synthetic resin, and pressed under heat and pressure. In addition to particle boards and density boards, the existing wood-based panels also include plywood and bamboo-wood composite boards. Wood floors, furniture,...

Problems solved by technology

During the spraying process, the agent will splash around in the spray chamber, and the splashed agent will not adhere to the surface of the board. In the prior art, this part of the agent is directly discharged as waste liquid, resulting in waste of agent

In addition, in the prior art, the spraying agent needs to be pre-prepared and then input into the spray gun to spray on the plate, which not only increases the process, but also some pre-prepared agents may react with the external environment for a long time, reducing the efficacy
