Description

Technical Field

[0001] The utility model relates to the technical field of melting furnace equipment, in particular to feeding equipment for a glass bottle processing melting furnace. Background Art

[0002] Glass melting refers to the process of melting qualified batch materials at high temperatures to form transparent, pure, uniform and suitable glass liquid for molding. Glass melting includes a series of physical and chemical phenomena and reactions; the results of these phenomena and reactions turn various batch materials into complex melts, namely glass liquid. The glass melting process can be roughly divided into five stages: the formation of silicate → the formation of glass liquid → the clarification of glass liquid → the homogenization of glass liquid → the cooling of glass liquid. After the glass liquid formation stage, the entire melt contains many bubbles (small bubbles with a diameter of less than 0.3 mm). The process of continuing to heat, reduce viscosity, and remove visible gas inclusions from the glass liquid is called the clarification of glass liquid, which is an important stage in the glass melting process. In actual production, we should try to increase the clarification temperature to reduce the viscosity of the glass liquid and promote the rapid removal of bubbles. The cooling of the glass liquid is the last stage of the melting process, and its purpose is to increase the viscosity of the glass liquid to the range required for molding. The cooling of the glass liquid must be uniform and cannot destroy the results of homogenization. Generally, natural cooling is adopted, mainly relying on the uniform heat radiation from the glass liquid surface and the pool wall and bottom to the outside for cooling.

[0003] Chinese utility model patent (authorization announcement number: CN216448620U name: a feeding device for a glass furnace with good feeding uniformity) It includes a base located on one side of the feeding port of the glass furnace, a connecting frame connected to the base through a rotating shaft, a rotating driving part is arranged between the base and the connecting frame; a mounting frame is slidably arranged on the connecting frame, a sliding driving part is connected between the mounting frame and the connecting frame; a conveyor belt extending into the glass furnace is connected to the mounting frame, and a loading hopper arranged toward the conveyor belt is connected to the connecting frame. The utility model can not only reduce the equipment cost, but also has the advantages of good feeding uniformity, good transmission stability and less pollution. However, the conveyor belt directly feeds the powdered glass raw materials into the glass furnace for heating and melting. Since the furnace is in an open state, there is a lot of heat loss and energy waste. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 , 3 As shown in Figure 5, a feeding device for a glass bottle processing furnace includes a hopper 1 and a guide channel 2. The hopper 1 is fixed at the feeding end of the guide channel 2, and the guide channel 2 is fixed at the feeding port of the furnace. A baffle 3 and B baffle 4 are hinged in the guide channel 2. The A baffle 3 is close to the feeding end of the guide channel 2, and the B baffle 4 is close to the discharge end of the guide channel 2. A preheating cavity is formed in the guide channel 2 through the A baffle 3 and the B baffle 4. A spring 5 is fixed on the B baffle 4, and the other end of the spring 5 is fixed to the top of the preheating cavity. On the inner wall, the B baffle 4 closes the discharge end of the preheating chamber through the spring 5. When the raw materials gather to a certain amount, the B baffle 4 is pushed open by gravity to enter the furnace. The alternating opening of the A baffle 3 and the B baffle 4 can keep the feed end of the furnace closed, reducing heat loss and saving energy. The powdered raw materials entering the material guide channel 2 stay in the preheating chamber for a short time for preheating, shortening the melting time after entering the furnace, further saving energy, and thus reducing the cost of glass production.

[0025] In this embodiment, if Figure 5 As shown, baffle plate B 4 is provided with air holes, which allow more heat to enter the preheating cavity to speed up the preheating of the powder in the preheating cavity.

[0026] In this embodiment, if Figure 5 As shown, a limit block 6 is fixed in the preheating chamber, and the B baffle 4 is pressed against the limit block 6 by the spring 5 to prevent the spring 5 from causing the B baffle 4 to reset excessively, resulting in the discharge end of the preheating chamber being not closed tightly.

[0027] In this embodiment, if Figure 2 and 3As shown, the hopper 1 is rotatably mounted with a main shaft 7 near the material guide channel 2, and a plurality of scraper plates 8 are fixed on the main shaft 7. The scraper plates 8 extend along the axial direction of the main shaft 7, and the plurality of scraper plates 8 are evenly distributed around the circumference of the main shaft 7. The scraper plates 8 are rotated to discharge the material, thereby reducing the probability of powder arching in the hopper 1 (after the powder material is stored in the silo for a certain period of time, due to the adhesion and friction of the powder, an upward supporting force may be generated in a certain material layer. When the supporting force is balanced with the pressure of the material above the material layer, the material layer below is in a static equilibrium state, and an arching phenomenon occurs).

[0028] In this embodiment, if Figure 4 As shown, a mounting plate 9 is fixed to the discharge end of the material guide channel 2. The mounting plate 9 is in a U-shape, and through holes are provided at the four corners of the mounting plate 9. A sealing groove 10 is provided on the surface of the mounting plate 9 close to the furnace, and a graphite packing is installed in the sealing groove 10, which improves the sealing performance of the installation location of the material guide channel 2 and reduces the risk of heat energy loss from the installation location.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
