Description

Technical Field

[0001] The utility model relates to a glass panel production tempering furnace, in particular to a glass panel production tempering furnace with a rapid cooling mechanism. Background Art

[0002] The manufacturing process of glass panels includes multiple complex steps, such as ultra-high temperature tempering, ultrasonic cleaning, precision silk screen printing and vacuum coating, which ensure the accuracy and durability of the glass panels. In electronic products, glass panels not only provide protection, but also increase the beauty and durability of the products.

[0003] A tempering furnace is a device that produces tempered glass using physical or chemical methods.

[0004] During use, the existing tempering furnace used for glass panel production changes the blowing direction of the cooling gas through the wind grille. However, the wind grille is easily contaminated with a large amount of dust during long-term use. This dust is easily attached to the glass panel along with the cooling gas, reducing the neatness of the product. In addition, the glass panel cannot be cooled quickly after heating, resulting in a long cooling time, which increases the production time and affects the production efficiency. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a glass panel production tempering furnace.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a glass panel production tempering furnace, comprising a tempering furnace body, wherein two grooves are respectively provided on the front and back sides of the inner wall of the tempering furnace body, a lower water tank is bolted to the lower surface of the inner wall of the tempering furnace body, an upper water tank is bolted to the upper surface of the inner wall of the tempering furnace body, a filter box is fixedly connected to the front side of the tempering furnace body, a convection component is arranged on the right side of the filter box, a circulation component is arranged inside the lower water tank, the left and right sides of the upper surface of the lower water tank are respectively connected to the lower surface of the upper water tank through a plurality of circulating cooling pipes, a temperature conduction box is installed on the right side of the lower water tank, and a cooling component is arranged inside the temperature conduction box.

[0007] Preferably, the cooling assembly comprises a semiconductor refrigeration plate installed on the left side of the inner wall of the temperature conduction box, and a heat dissipation fan is installed at the heat dissipation end of the semiconductor refrigeration plate.

[0008] Preferably, the circulation assembly includes a water pump installed on the lower surface of the inner wall of the lower water tank, and the drainage end of the water pump is connected to the back side of the upper water tank through a drainage pipe.

[0009] Preferably, the convection component includes an air pump installed on the right side of the filter box, the air suction end of the air pump is connected to the upper surface of the filter box through an air suction pipe, the exhaust end of the air pump is connected to the air inlet end of the diverter pipe through an exhaust pipe, and the diverter pipe is installed on the lower surface of the inner wall of the groove.

[0010] Preferably, a plurality of connecting pipes are symmetrically mounted on the upper surface of the diverter pipe, and a plurality of nozzles are symmetrically mounted on the back surface of the connecting pipe.

[0011] Preferably, a filter element is bolted inside the filter box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model uses a water pump to draw water from the lower water tank and discharge it into the upper water tank through a drain pipe. The water returns to the lower water tank through a plurality of circulating cooling pipes under the action of its own weight. The heat emitted by the glass panel inside the tempering furnace body is absorbed and exchanged through the circulating cooling pipe. The air extraction pump draws air from the filter box and discharges it into the diverter pipe and the connecting pipe through the exhaust pipe, and is sprayed out through the nozzle. Two groups of opposite connecting pipes and nozzles spray air flows in correspondence with each other. The sprayed air passes through the circulating cooling pipe, and the cold water inside the circulating cooling pipe exchanges heat with the air to form cold air convection, thereby accelerating the cooling of the glass panel. This solves the problem that the existing device cannot cool down quickly after heating, resulting in excessively long cooling time, increased production time, and affected production efficiency.

[0014] The utility model filters and purifies the air in the filter box through the filter element, and the air in the filter box is extracted by the vacuum pump, and is discharged into the shunt pipe and the connecting pipe through the exhaust pipe, and is sprayed out through the nozzle. The two sets of opposite connecting pipes and nozzles spray air flows corresponding to each other, so as to form air convection to accelerate the cooling of the glass panel and avoid dust contamination of the glass panel, thereby solving the problem that the existing device is easily contaminated with a large amount of dust during long-term use, and the dust is easily attached to the glass panel with the cooling gas, thereby reducing the neatness of the product.
