Description

Excessive environment-friendly hot pressing plywood manufacturing installation of no VOCs

Technical Field

The utility model belongs to the technical field of the plywood preparation, especially, relate to an excessive environment-friendly hot pressing plywood manufacturing installation of no VOCs.

Background

In the production process of the plywood, hot pressing is a crucial process link. Generally, the slabs with different thicknesses and different curvatures are manually placed into heating plate layers of a hot press with the layer spacing of 5-8cm layer by layer, and the surface temperature of each hot pressing plate is maintained at 120-. The hot press with the new plate blank is lifted to the hot pressing height by the power provided by the matched hydraulic press, the plate blank is hot extruded and bonded into a shaped product under the condition of keeping a certain pressure for a certain time, and the height of the hot press is reduced by the hydraulic press according to the working procedure. And then, manually taking out the product and feeding in a new plate blank, thereby completing a work flow. When the height of the hot press is reduced, the hydraulic press needs to release kinetic energy to the oil storage tank, so that each hot pressing layer of the hot press is reduced to the height required by feeding the slab and taking out the product.

The overflow of VOCs is mainly generated in the hot pressing process, and only a small amount of residual VOCs overflows in the processes of feeding the plate blank and taking out the product. In the hot pressing process of the plywood, the adhesive is subjected to chemical reaction at high temperature, part of organic components are heated and volatilized, VOCs generated in the process accounts for more than 70-90% of the generation amount of VOCs generated in the processing technology of the plywood, and the main component of the VOCs is formaldehyde. The hot press of plywood trade is mostly open-type operation, and the airtight degree of main part is very low, only installs the gas collecting channel additional at the hot press top, and what can collect only is that the hot press is close to the formaldehyde VOCs waste gas of draught fan part, and most unorganized VOCs waste gas is not collected, and the loss is to the workshop. The formaldehyde with strong irritation strongly irritates eyes, nose, throat and other organs of workers in a workshop, seriously influences the health of the workers in the workshop and seriously pollutes the surrounding air environment. And after the hot pressing is finished, residual formaldehyde and a small amount of formaldehyde waste gas are discharged although the formaldehyde discharge amount is greatly reduced.

Therefore, in order to prevent the pollution of the unorganized VOCs waste gas generated in the hot pressing process of the plywood, the hot press is preferably fully closed in a collection mode, the waste gas in the hot pressing process is intensively discharged through the fan, the overflow of the residual VOCs waste gas after the waste gas is sent into the plate blank and taken out of the product is reduced as far as possible, and the waste gas in the whole production process is sent to a waste gas treatment device for purification and then is discharged. If the hot press is completely sealed, the feeding and discharging operations of the hot press are affected, the production efficiency is reduced, and the sealing difficulty is high; the manual feeding and discharging operation is a feeding and discharging mode of the main hot press, so that the sealing difficulty is greatly increased; the utilization rate of the existing automatic feeding and discharging machine is reduced by the plate blanks with different thicknesses and different curvatures; the development difficulty of the environment-friendly multifunctional hot-pressed plywood automatic feeding and discharging process and device without VOCs overflow is greatly increased under the combined action of the three components.

In addition, the feeding and discharging machine in the market at present can only be suitable for a single thick plate type with smaller bending degree, and only meets the requirement of automatic feeding equipment for hot pressing of thick plates, the price of each machine is more than 10 ten thousand, which is about 50% of the price of a hot press, the energy consumption of operation is about more than 50% of the energy consumption of the hot press, and the burden of a micro-profit plywood manufacturer is increased.
