Description

Novel efficient energy-saving impregnation furnace

Technical Field

The utility model discloses be applied to the technical field of gumming equipment, in particular to novel energy-efficient gumming stove.

Background

Grinding wheel meshes generally fall into two categories: one is a non-woven fabric composite mesh and a black paper composite mesh, and the other is a pure mesh, which is widely used as a reinforcing base material of a resin adhesive grinding wheel. The grinding wheel made of the base material has excellent heat resistance, high-speed cutting performance and high structural strength. The grinding wheel net sheet is formed by coating glass fiber reinforced net cloth with phenolic aldehyde and epoxy modified resin, baking and punching. At present, a dipping machine or a dipping furnace is generally adopted to process a glass fiber reinforced web, the dipping machine comprises a glue tank, in order to fully coat the glass fiber reinforced web with reinforcing glue, the soaking time of the glass fiber reinforced web in the glue tank is usually prolonged, the longer the soaking time is, the lower the production efficiency is, and the production requirements of enterprises cannot be well met, for example, a Chinese patent with the publication number of 109371605A discloses a dipping device for producing woven glass fiber mesh cloth, the automatic dipping of glass fiber cloth is realized through automatic traction, heating and drying are carried out through a heating plate, however, the drying effect is poor, and the drying effect of the glass fiber cloth during winding cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the prior art is not enough to overcome, and provides a novel energy-efficient gumming furnace with good heating effect and high production efficiency.

The utility model adopts the technical proposal that: the utility model discloses a feed cylinder, steeping vat, heating furnace and receipts material roller that set gradually, the top of heating furnace body is provided with heater and fan, the heating furnace is including output chamber, heating chamber and chamber of admitting air, the chamber of admitting air through a plurality of fumaroles with heating chamber intercommunication, the bottom in heating chamber with output chamber intercommunication, the output chamber the fan the heater and the chamber of admitting air communicates in proper order, the bottom in heating chamber is rotated at least and is provided with two first deflector rolls that cure, the top in heating chamber is rotated at least and is provided with a second and cures the deflector roll.

According to the scheme, the mesh fabric is fed into the heating furnace for baking after passing through the impregnation tank from the charging barrel for impregnation, and the material receiving roller is used for winding the baked mesh fabric. Through the fan drives the air current and passes the heater realizes doing the chamber of admitting air provides the high temperature air current, and is through adopting a plurality of the fumarole carries out jet-propelled heating, guarantees that steam gets into there is certain initial velocity during the heating chamber, makes the heat can be more even and heat the screen cloth fast and bake. Adopt simultaneously the bottom in heating chamber with the design of output chamber intercommunication, need pass through when making the steam backward flow the bottom in heating chamber guarantees that all screen cloths all can receive the heating. The fan admits air from the output cavity, and then retrieves residual heat, reduces the power that the heater needs to consume when keeping the temperature. The first baking guide roller and the second baking guide roller are used for guiding the mesh cloth, so that the mesh cloth moves in the heating cavity for a certain time.

One preferred scheme is, the utility model discloses still include driving motor, driving motor with it connects to receive the material roller transmission.

According to the scheme, the driving motor drives the material receiving roller to move, and then automatic material receiving is achieved.

One preferred scheme is that a first guide roller is arranged between the impregnation tank and the heating furnace, a second guide roller is arranged between the material receiving roller and the heating furnace, the first baking guide roller close to the air inlet cavity is matched with the first guide roller, and the first baking guide roller close to the output cavity is matched with the second guide roller.

According to the scheme, the first guide roller and the second guide roller are arranged to guide the mesh cloth, so that the mesh cloth moves along a set path.

A glue dipping roller is rotatably arranged in the glue dipping tank, the horizontal height of the first guide roller is higher than the top of the glue dipping tank, and the horizontal height of the second guide roller is lower than the horizontal height of the material receiving roller.

According to the scheme, the impregnation roller is arranged to guide the mesh cloth, so that the mesh cloth is immersed in the glue solution. The first guide roller is arranged above the impregnation tank, so that the mesh cloth is prevented from contacting other parts and being polluted by dust after impregnation is completed.

Preferably, a waste heat discharge port is arranged at the top of the heating cavity, and a sealing cover and a filter are arranged on the waste heat discharge port.

According to the scheme, the waste heat discharge port is arranged to discharge high-temperature gas after shutdown, so that accelerated cooling is realized. Through setting up the closing cap seals when the during operation, guarantees that sufficient temperature heats and cures in the heating chamber. The filter is of a structure such as filter cotton or a filter element, and the filter filters glue solution steam to prevent environmental pollution.

Preferably, both ends of the first baking guide roller and the second baking guide roller penetrate out of the furnace wall of the heating furnace, cooling channels are arranged inside the first baking guide roller and the second baking guide roller, and both ends of each cooling channel are communicated with external cooling liquid circulation equipment through rotary joints.

It can be seen by above-mentioned scheme that through first bake the deflector roll and set up in the second cures the deflector roll cooling channel to let in the coolant liquid and cool off, reduce the temperature of its working face, prevent that the glue solution of screen cloth is in because of high temperature sintering or bonding on the working face, ensure that the screen cloth is in the motion in the heating furnace is unimpeded. Because the first deflector roll that cures and the second cures the deflector roll and all need last the rotation, through adopting rotary joint as connection structure, realize that the water supply pipe does not follow the first deflector roll that cures and the rotation of second curing deflector roll rotates, ensures the work that the coolant liquid pipeline can normally last.
