Description

Technical Field

[0001] The invention belongs to the technical field of substrate glass manufacturing, and in particular relates to a dustproof and lubricating top screw mechanism for advancing a pool furnace electrode. Background Art

[0002] In the process of glass substrate production and manufacturing, the pool furnace is a key equipment for melting glass batch materials to form glass liquid. During the use of the pool furnace, due to the erosion of the electrodes, the electrode spacing becomes larger, resulting in a decrease in the Joule heat generated, which cannot meet the requirements of melting the glass liquid in the pool furnace. The electrode needs to be pushed by the pool furnace electrode propulsion device to meet the requirements of the pool furnace electrode spacing. However, during the use of the pool furnace electrode propulsion device, since the top screw mechanism is in a high temperature and high dust environment, dust and other pollutants are easily attached to the surface of the top screw; at the same time, the top screw thread uses solid lubricant, which will become ineffective and solidified if it is in a high temperature and high dust environment for a long time; these may cause the top screw mechanism of the pool furnace electrode propulsion device to have problems such as thread jamming or inability to rotate easily, which greatly affects the service life of the top screw. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a dustproof lubricating screw mechanism for advancing a pool furnace electrode. The present invention can realize that the screw in the pool furnace electrode advancing device is in a closed environment, avoiding problems such as the screw thread being stuck or being unable to rotate easily due to the high temperature and high dust environment outside, and greatly improving the service life of the screw.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] A dustproof and lubricating push screw mechanism for advancing a pool furnace electrode comprises a dustproof sleeve and an advancing screw, wherein the dustproof sleeve comprises an upper dustproof sleeve and a lower dustproof sleeve, and the upper dustproof sleeve and the lower dustproof sleeve form a closed space; the middle portion of the advancing screw is arranged in the closed space, and both ends of the advancing screw are respectively provided with an insulating sleeve and a nut; the dustproof sleeve is installed on a fixed column, and the top end of the fixed column is fixedly connected to a mounting plate, and the bottom end is fixedly connected to a square steel, and the mounting plate and the square steel are used to cooperate to fix the position of the fixed column.

[0006] Preferably, the advancing screw comprises an advancing block, and a first screw and a second screw are respectively fixed at two ends of the advancing block.

[0007] Preferably, one end of the first screw is fixedly connected to the propulsion block, and the other end is fixedly connected to a nut.

[0008] Preferably, a scale is provided on the first screw.

[0009] Preferably, the push block is cylindrical and is provided with an external thread; the enclosed space of the dust cover is provided with an internal thread that matches the external thread of the push block; the push block is threadedly connected in the enclosed space of the dust cover.

[0010] Preferably, the propulsion block is provided with a plurality of through holes along the axial direction for the passage of lubricating oil.

[0011] Preferably, a plurality of vertical grooves are provided at the circumferential edge of the propulsion block for the passage of lubricating oil.

[0012] Preferably, the upper dust cover is provided with an oil inlet; and the lower dust cover is provided with an oil outlet.

[0013] Preferably, the lubricating oil level is lower than the radius of the dust cover.

[0014] Preferably, one end of the second screw is fixedly connected to the propulsion block, and the other end is fixedly connected to the insulating sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention places the push block in the pool furnace electrode push device in a closed environment, avoiding problems such as thread jamming or inability to rotate easily caused by the push block being in an external high temperature, high dust environment, etc., thereby greatly improving the service life of the top screw.

[0017] 2. The present invention adopts a threaded connection between the external thread of the push block and the internal thread in the dust cover to form a closed space. The radial movement of the push block inside the dust cover is achieved by rotating the nut of the first screw, thereby realizing the push of the electrode by the top screw. The push block has through holes or vertical grooves evenly distributed around the edge to prevent the push block from being unable to advance due to the lack of circulation of lubricating oil in the closed space on the left and right during the advancement process.

[0018] 3. The present invention adds high-temperature resistant liquid lubricating oil into the enclosed space formed by the upper and lower dust covers, and the liquid level of the lubricating oil is lower than the radius value of the dust covers, which can ensure that the thrust block is always immersed in the lubricating oil, reducing the resistance of the thrust block, making the rotation and advancement process of the thrust block easier and more convenient; at the same time, the upper and lower dust covers are provided with oil inlets and outlets, which are convenient for adding and replacing the lubricating oil.
