Description

Technical Field

[0001] The utility model relates to the technical field of float glass manufacturing, in particular to a tin bath ash removal pool device. Background Art

[0002] The tin bath is an important equipment in float glass manufacturing technology. The tin bath body contains molten tin, and the glass ribbon floats on the molten tin as a floating medium. The molten tin in the tin bath will chemically react with the leaked oxygen to form tin ash, which floats on the surface of the molten tin and has a great impact on the quality of the glass, especially at the end wall of the tin bath where tin ash is easily accumulated.

[0003] The conventional way to clean tin ash is to install ash cleaning devices on both sides of the tin bath near the tail end. There are usually two types of ash cleaning devices: one is to set narrow tin liquid grooves symmetrically on the side wall near the tail end of the tin bath, called "small ear pools". A linear motor is installed on each small ear pool, which uses its electromagnetic force to attract tin liquid and floating tin ash into the small ear pool, and then filter the clean tin liquid back into the tin bath. The second type is a relatively large mechanical ash scraping pool that protrudes more than one meter from the outside of the tin bath. This type of ash scraping pool is also called a "big ear pool". A graphite runner is installed at the interface between the big ear pool and the tin bath, and the runner blades push the tin ash into the big ear pool.

[0004] The advantages of the small ear pool of the linear motor are its small size and good ash absorption effect; the main disadvantage is that the ear pool has a small capacity, and tin ash often covers the small ear pool like duckweed, which prevents the tin ash from continuing to enter the small ear pool. It is necessary to frequently open the side seal to remove the ash. During operation, air easily leaks into the tin tank and pollutes the tin liquid. Although the mechanical ash-scraping large ear pool has a large capacity, it is extremely dependent on the natural flow of tin liquid in the tin tank to gather the tin ash to the two sides of the very end of the tin tank, so that the graphite wheel blades can push the tin ash into the large ear pool. Therefore, its installation position must be at the very end of the tin tank. Its large volume almost occupies the emergency operation position of the broken glass plate at the end of the tin tank, and its ash absorption effect is not as good as that of the small ear pool of the linear motor. Utility Model Content

[0005] The utility model aims to provide a tin bath ash scraping pool device which has good ash absorbing effect and does not affect the emergency operation position of glass breakage.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] Preferably, the tin liquid groove outlet is a submerged outlet located below the tin liquid surface.

[0009] Preferably, the thrust direction of the linear motor is opposite to the moving direction of the glass ribbon.

[0010] Preferably, the partition wall is provided with a slope on the side close to the ash removal pool.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a tin bath ash scraping pool device which is applied to both sides of the tail end of a float glass tin bath. The entire tin bath ash scraping pool device is made of refractory material and a steel shell.

[0022] like Figure 1-3 As shown, the tin bath ash scraping pool device includes: a tin liquid groove 1, a linear motor 2, an ash scraping pool 3, an ash scraping rake 4 and an ash storage tank 5; the tin liquid groove 1 is located on the side walls on both sides of the rear end of the tin bath, and the tin liquid in the tin liquid groove 1 is separated from the tin liquid in the tin bath by the inner side walls. The tin liquid in the tin bath can only be circulated through the tin liquid groove inlet 8 and the tin liquid groove outlet 9, wherein the tin liquid groove inlet 8 is connected to the inner side of the rear end wall of the tin bath where tin ash is easily gathered, and the tin liquid groove outlet 9 is connected to the rear end wall of the tin bath several meters upstream, and the opening of the side wall at the rear end of the tin bath can be directly used as the tin liquid groove inlet 8, and the opening of the side wall at the upstream position of the rear end can be used as the tin liquid groove outlet 9. The linear motor 2 is installed above the tin liquid groove 1, and the thrust direction of the linear motor 2 when working is opposite to the moving direction of the glass ribbon. The electromagnetic force generated when working can attract the tin liquid in the tin bath to flow to the tin liquid grooves 1 on both sides. The ash scraping pool 3 is horizontally arranged at the outlet of the tin liquid groove, that is, the outlet of the tin liquid groove 1 is opened near the side wall of the tin tank for communicating with the tin tank, and the ash scraping pool 3 with a large enough capacity is arranged on the side away from the side wall of the tin tank, and the ash scraping pool 3 is connected to the tin liquid groove 1. The ash storage tank 5 is located outside the ash scraping pool 3 and is separated from the ash scraping pool 3 by a partition wall. The height of the partition wall is higher than the height of the tin liquid level in the tin liquid groove 1, so as to prevent the tin liquid in the tin liquid groove 1 / ash scraping pool 3 from actively flowing into the ash storage tank 5. The ash scraping rake 4 is used to scrape the tin ash floating on the tin liquid level in the ash scraping pool 3 into the ash storage tank 5 for collection. The ash scraping rake 4 can be automatic or manual. The periphery of the tin tank ash scraping pool device is provided with a sealed steel shell 6, and the steel shell on one side of the ash scraping pool 3 is provided with a sealed bellows 7. The ash scraping rake 4 extends into the ash scraping pool 3 through the sealed bellows 7, and the sealed steel shell 6 prevents air from leaking into the tin tank.

[0023] In a specific implementation of the utility model, the tin liquid groove outlet 9 is a submerged outlet located below the liquid level of the tin liquid in the tin tank, and the tin liquid groove inlet 8 is an open inlet; the bottom of the ash scraping pool 3 is lower than the bottom of the tin liquid groove 1, and a connecting inclined surface is provided at the height difference position of the bottom, and the ash scraping pool 3 can stabilize the tin liquid to facilitate further dust cleaning operations. When the tin liquid containing tin ash flows into the tin liquid groove 1 and approaches the outlet, the tin ash floating above the tin liquid is intercepted at the submerged outlet, which prevents the tin ash from being directly discharged from the tin liquid groove 1. Since the outlet end of the tin liquid groove 1 is connected to the ash scraping pool 3, the tin ash will gather in the ash scraping pool 3, and the tin ash can be scraped into the ash storage tank 5 by the ash scraping rake 4, and the clean tin liquid flows back to the tin tank through the submerged outlet. In order to facilitate the operation of the ash scraping rake 4, an inclined surface can be set on the side of the partition wall close to the ash scraping pool 3, the sealing bellows 7 is located higher than the liquid level of the tin liquid, and the ash scraping rake 4 extends downward into the ash scraping pool 3. The setting of the inclined surface avoids the dead corner of the tin ash.

[0024] The working process of the above-mentioned tin bath ash removal pool device includes:

[0025] Tin bath dust removal pool devices are symmetrically arranged on both sides of the tin bath, and a pair of linear motors 2 are controlled to work in a thrust direction from downstream to upstream. Here, upstream and downstream refer to the direction of glass movement from upstream to downstream. The continuous glass ribbon floating on the tin liquid moves continuously from upstream to downstream, driving the surface tin liquid to flow downstream. When the tin liquid is blocked by the end wall at the outlet of the tin tank, most of the liquid flow will turn downward and become a deep reflux in the opposite direction of the movement of the glass ribbon. This reflux is called "under-plate reflux". A small part of the tin liquid will turn 90 degrees in the plane and flow to the edge, and flow back upstream in the gap between the glass plate and the side wall not covered by the glass. This reflux is called "out-of-plate reflux". Under the action of the out-of-plate reflux and the electromagnetic force of the linear motor 2, the tin liquid containing tin ash on the inner side of the rear end wall of the tin tank flows into the tin liquid grooves 1 on both sides, flows through the narrow and long tin liquid groove 1 and reaches the ash scraping pool 3 at the outlet end of the tin liquid groove 1, and the ash scraping rake 4 is automatically or manually controlled to scrape out the floating tin ash 10 on the surface of the tin liquid, and the scraped tin ash 11 remains in the ash storage tank 5, and the clean tin liquid flows back to the tin tank from the tin liquid groove outlet 9 to complete the cycle.

[0026] The above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and there are many variations. All variations that can be directly derived or associated with the contents disclosed by a person skilled in the art from the present invention should be considered as the protection scope of the present invention.
