Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical glass manufacturing, in particular to an electric melting furnace for pharmaceutical glass manufacturing. Background Art

[0002] Pharmaceutical glass refers to glass specially used for drug packaging, generally referring to glass bottles and containers. When manufacturing pharmaceutical glass, unqualified glass will be melted by electric melting and then processed into glass that meets the requirements. Therefore, electric melting furnaces play an important role in the manufacture of pharmaceutical glass.

[0003] For example, the publication number CN218202516U discloses a vertical electric glass melting furnace, including a furnace body, a melting chamber and a clarification chamber are arranged inside the furnace body, a material guide tube is arranged at the top of the furnace body, and a tube plug is inserted into the inside of the material guide tube. The tube plug of the utility model plugs the material guide tube. When it is necessary to add material, the tube plug is turned upwards and the top of the material guide tube is still plugged, so that the bottom end of the feed tube is connected to the material guide tube, and the material in the material storage box is added into the furnace body through the feed tube. The high-temperature heat inside the furnace body is not dissipated, and the melting of the glass inside the furnace body is not affected. The partition plate separates the melting chamber and the clarification chamber, and the stirring rod is spaced apart from the first electrode group and the second electrode group respectively. In this way, the stirring rod fully stirs the molten glass in the melting chamber and the clarification chamber, so that the molten glass is heated sufficiently and evenly;

[0004] However, the electric melting furnace in the above application still has some shortcomings during use. For example, when the inside of the electric melting furnace needs to be cleaned, the parts inside the electric melting furnace cannot be separated, resulting in insufficient cleaning, which affects the subsequent glass processing and reduces the use effect of the electric melting furnace. Therefore, we propose an electric melting furnace for pharmaceutical glass manufacturing to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric melting furnace for manufacturing pharmaceutical glass, comprising a horizontally placed furnace body and a support frame installed on the outer wall of the furnace body;

[0012] Preferably, the top cover and the furnace body are fitted together, and the hydraulic rods on the outer wall of the furnace body are distributed at equal angles, so that the top cover and the furnace body can be separated by the hydraulic rods.

[0013] Preferably, the stirring blade and the first electrode group are both connected to the rotating shaft by bolts, and the stirring blade and the first electrode group are staggered in distribution, and the length of the stirring blade is greater than the length of the first electrode group.

[0014] Preferably, the filter is mounted on the inner wall of the fixed frame, and a docking block is provided on the lower surface of the fixed frame, and the docking block is connected to the limit block, and the filter is connected to the rotating shaft by a bearing.

[0015] Preferably, the docking block and the fixed frame are an integrated structure, and the docking block and the limiting block are snap-fitted, and the limiting block is welded to the inner wall of the furnace body, while the fixed frame and the inner wall of the furnace body fit each other.

[0016] Preferably, a positioning rod is installed on the upper surface of the fixing frame, and one end of the positioning rod away from the fixing frame is connected to the inner wall of the top cover, and the positioning rod and the fixing frame are welded.

[0017] Preferably, a second electrode group is fixed to the inner wall of the furnace body by bolts, and the second electrode groups are distributed at equal angles, and there is a gap between the second electrode group and the stirring blades.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the electric melting furnace for manufacturing medical glass can separate the top cover from the furnace body by pushing the top cover through the hydraulic rod, so that the internal parts can be removed and better cleaned, as shown in the following content:

[0019] (1) The top cover and the furnace body fit together, and the hydraulic rods on the outer wall of the furnace body are distributed at equal angles. When the hydraulic rods are working, they can drive the top cover to move up and down, so that the top cover and the furnace body are closed and separated;

[0020] Furthermore, the top cover is connected to the fixed frame through a positioning rod, and a filter screen is installed on the inner wall of the fixed frame, and the filter screen and the rotating shaft are connected by a bearing.

[0022] Furthermore, by setting the filter, the glass that is not completely melted can be intercepted, so that the glass is retained in the cavity above the filter and continues to be melted, while the molten glass flows out from the pores of the filter and is melted again under the action of the second electrode group, so that the glass is melted more fully;

In this way, under the action of the limit block, the filter can be more stable when in use. At the same time, when the filter rises, it does not affect the separation of the filter, further ensuring the normal progress of the cleaning work. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1:

[0034] In this embodiment, a feed pipe 4 installed on the top cover 3 is used to put the broken glass and the molten glass into the feed pipe 4. Figure 1-Figure 2 As shown:

[0035] A top cover 3 is provided on the top of the furnace body 1, and a feed pipe 4 is installed on the top cover 3, and a drive motor 6 is fixed by bolts at a position just above the top cover 3;
