Description

Technical Field

[0001] The utility model relates to the field of glass kilns, and more specifically, to a clarifying material channel filtering mechanism. Background Art

[0002] The molten glass melted in the glass furnace will be discharged through the clarification channel. During the flow, impurities in the molten glass will sink to the bottom and be discharged through the slag discharge port at the bottom of the clarification channel. In the actual production process, due to the high viscosity of the molten glass and the complex structure of the uphill section of the clarification channel, turbulence is easily generated during the flow of the molten glass, which will carry large particles of impurities into the clarification channel and flow forward. It is difficult to capture all impurities at the traditional slag discharge port, affecting the production quality of the glass.

[0003] If multiple slag discharge ports are provided, the glass melt will leak out and be wasted, thus affecting the output and production cost.

[0004] Therefore, a filtering mechanism for clarifying the material channel is needed to solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the existing slag discharge structure has a poor slag discharge effect or easily causes glass melt to leak and waste.

[0006] According to one aspect of the utility model, a clarifying material channel filtering mechanism is provided, comprising a melting pool, a clarifying material channel and a climbing channel, wherein the melting pool and the clarifying material channel are connected via the climbing channel, a slag discharge hole is provided at the bottom of the climbing channel, a lower retaining wall is provided at the top of the climbing channel, and the lower retaining wall is a ceramic filter plate.

[0007] Through this solution, the upwelling molten glass is filtered by a ceramic filter plate, and the clarified molten glass after filtration enters the clarifying channel, while impurities with larger particles are filtered out by the ceramic filter plate, so that the larger impurities roll along the climbing channel into the slag discharge hole and are discharged. The setting of the ceramic filter plate can reduce the generation of turbulence, thereby preventing large particles from being entrained and directly crossing the lower retaining wall into the clarifying channel.

[0008] Preferably, the filter mesh on the ceramic filter plate is only arranged on the upper half of the ceramic filter plate.

[0009] This solution prevents tiny impurity particles from entering the clarification channel through the filter mesh at the bottom of the ceramic filter plate, thereby losing the blocking effect of the lower retaining wall.

[0010] Preferably, it also includes a cleaning mechanism, which includes a ceramic scraper and a driving mechanism. The driving mechanism drives the ceramic scraper to move in a vertical direction along the lower retaining wall, and the ceramic scraper is gap-matched with the front side of the lower retaining wall.

[0011] Through this solution, the cleaning mechanism can push the filtered large particles of impurities downward to fall onto the climbing channel, preventing the flow pressure from squeezing the large particles of impurities to block the filter mesh and affect the filtering effect.

[0012] Preferably, an upper retaining wall is provided above the bottom of the climbing channel, the ceramic scraper is provided between the lower retaining wall and the upper retaining wall, and the ceramic scraper is gap-matched with the upper retaining wall.

[0013] Through this solution, the upper retaining wall can guide the movement of the ceramic scraper.

[0014] Preferably, a through groove is provided on the kiln above the climbing passage, the ceramic scraper extends upward from the through groove and is slidably connected thereto, and the driving mechanism is located outside the kiln.

[0015] Through this solution, the driving mechanism is located outside the kiln, which reduces the impact of high temperature on it and increases its service life, and only the high-temperature resistant ceramic scraper is extended into the kiln.

[0016] Preferably, the driving mechanism comprises a mounting frame and a driving cylinder, the driving cylinder is mounted on the mounting frame, and the mounting frame is in an arc shape matching the kiln and is fixed to the kiln.

[0017] Through this solution, the kiln is made of refractory materials such as refractory bricks, which can isolate most of the temperature and prevent the temperature from being transferred to the driving cylinder and causing damage to it.

[0018] Preferably, a polished rod is fixed on the top of the ceramic scraper, and the polished rod is slidably connected to the mounting frame.

[0019] Through this solution, the polished rod can guide the up and down movement of the ceramic scraper to prevent it from shaking due to friction, affecting the structure of the kiln or affecting the service life of the driving cylinder.

[0020] Preferably, filtering holes are provided at the bottom of the ceramic scraper.

[0021] Through this solution, the ceramic scraper can also filter part of the molten glass during operation, thereby avoiding the problem of low production efficiency caused by the ceramic scraper affecting the flow of the molten glass.

[0022] One of the technical effects of the utility model is that the clarification channel filtering mechanism can directly filter the molten glass, reduce the generation of turbulence, and thus avoid large particle impurities from crossing the lower retaining wall into the clarification channel, thereby improving the clarification effect and clarification efficiency; and the device can clean the ceramic filter plate, avoiding frequent maintenance due to clogging of the lower filter holes due to long-term use.

[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] like Figures 1 to 5 As shown, the clarifying channel filtering mechanism in one embodiment of the present application includes a melting pool 101, a clarifying channel 102 and a climbing channel 103. The melting pool 101 and the clarifying channel 102 are connected via the climbing channel 103. A slag discharge hole 104 is provided at the bottom of the climbing channel 103. A lower retaining wall is provided at the top of the climbing channel 103, and the lower retaining wall is a ceramic filter plate 110.

[0036] Through the scheme of this embodiment, the ceramic filter plate 110 is used to filter the upwelling glass melt, and the clarified melt after filtration enters the clarifying channel 102, while impurities with larger particles will be filtered out by the ceramic filter plate 110, so that the larger particle impurities roll along the climbing channel 103 into the slag discharge hole 104 for discharge. The setting of the ceramic filter plate 110 can reduce the generation of turbulence, thereby preventing large particles from being entrained and directly crossing the lower retaining wall into the clarifying channel 102.

[0037] In one embodiment of the present application, the filter mesh 111 on the ceramic filter plate 110 is only provided in the upper half of the ceramic filter plate 110 to prevent fine impurity particles from entering the clarification channel 102 through the filter mesh 111 at the bottom of the ceramic filter plate 110, thereby losing the blocking effect of the lower retaining wall.

[0038] In one embodiment of the present application, a cleaning mechanism 200 is also included. The cleaning mechanism 200 includes a ceramic scraper 220 and a driving mechanism. The driving mechanism drives the ceramic scraper 220 to move along the vertical direction of the lower retaining wall. The ceramic scraper 220 is in clearance with the front side of the lower retaining wall. The cleaning mechanism 200 can push the filtered large particles of impurities downward to fall onto the climbing channel 103, so as to prevent the flow pressure from squeezing the large particles of impurities to block the filter mesh 111 and affect the filtering effect.

[0039] The ceramic filter plate 110 and the ceramic scraper 220 are both made of ceramic material, the melting point of the ceramic material is about 2000° C., while the melting point of the glass in the kiln 100 is about 1500° C. The size of the filter mesh 111 is determined according to the requirements of the glass product.

[0040] In one embodiment of the present application, an upper retaining wall 120 is disposed above the bottom of the climbing channel 103, and a ceramic scraper 220 is disposed between the lower retaining wall and the upper retaining wall 120, and the ceramic scraper 220 is gap-matched with the upper retaining wall 120. The upper retaining wall 120 can guide the movement of the ceramic scraper 220.

[0041] In one embodiment of the present application, a through slot 105 is provided on the kiln 100 above the climbing channel 103, the ceramic scraper 220 extends upward from the through slot 105 and is slidably connected thereto, and the driving mechanism is located outside the kiln 100. The driving mechanism is located outside the kiln 100 to reduce the influence of high temperature on it and increase its service life, and only the high temperature resistant ceramic scraper 220 is extended into the kiln 100.

[0042] In one embodiment of the present application, the driving mechanism includes a mounting frame 210 and a driving cylinder 230. The driving cylinder 230 is mounted on the mounting frame 210. The mounting frame 210 is an arc-shaped structure that matches the kiln 100 and is fixed to the kiln 100. The kiln 100 is made of refractory materials such as refractory bricks, which can isolate most of the temperature and prevent the temperature from being transferred to the driving cylinder 230 and causing damage thereto.

[0043] The temperature of the surface of the kiln 100 is about several tens of degrees Celsius, and the metal mounting frame 210 can maintain its inherent properties. The mounting frame 210 can be fixed to the ground or to the kiln 100 by means of expansion bolts and the like.

[0044] In one embodiment of the present application, a polished rod 211 is fixed to the top of the ceramic scraper 220, and the polished rod 211 is slidably connected to the mounting frame 210. The polished rod 211 can guide the up and down movement of the ceramic scraper 220 to prevent it from shaking due to friction, affecting the structure of the kiln 100 or affecting the service life of the driving cylinder 230.

[0045] The polished rod 211 and the piston rod of the driving cylinder 230 do not directly extend into the kiln 100, but are only intermittently extended into the kiln 100 by the bottom of the ceramic scraper 220 for cleaning. An iron sheet and other devices are fixed on the top of the ceramic scraper 220 to facilitate the installation and fixation of the polished rod 211 and the piston rod.

[0046] In one embodiment of the present application, a filter hole 221 is provided at the bottom of the ceramic scraper 220, so that the ceramic scraper 220 can filter part of the molten glass during operation, thereby preventing the ceramic scraper 220 from affecting the flow of the molten glass and causing low production efficiency.
