When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] The invention provides a material discharge device for glass preparation.

[0055] like Figure 1 , 2As shown in Figure 5, in one embodiment of the present invention, the discharge device for preparing glass comprises a discharge pipe 2, a discharge support shell 3 and a temperature regulating structure; a conveying channel 20 is provided in the discharge pipe 2, one end of the discharge pipe 2 is used for installation on the bottom of the kiln pool, and the conveying channel 20 is connected with the inside of the bottom of the kiln pool, and the conveying channel 20 is used for conveying and discharging glass; the discharge support shell 3 is provided with an opening 30 and a placement cavity 34 which are interconnected, and the other end of the discharge pipe 2 is connected to the opening 30 and is connected with the placement cavity 34; the temperature regulating structure is used to detect and control the temperature of the discharge pipe 2.

[0056] The technical solution of the present invention can separate the conveying and discharging and temperature adjustment processes by adopting a split discharge pipe 2 and a discharge support shell 3, reduce the risk of leakage at the discharge point due to hydrophobic erosion, and reduce the risk of uncontrolled hot glass outflow during the replacement of the discharge support shell 3, thereby improving the stability of the discharge and reducing the mutual influence; at the same time, the temperature of the discharge pipe 2 is controlled by the temperature adjustment structure to reach a preset temperature relatively suitable for discharge, so that the discharged glass can be discharged stably and quickly, avoiding the dangerous phenomenon of glass solidification and inability to discharge or uncontrolled discharge of glass; thereby, the discharge efficiency can be improved, which is helpful to improve the efficiency of glass preparation.

[0057] In some embodiments, the discharged glass is a pollutant-containing glass liquid or a heterogeneous glass liquid.

[0058] Among them, in some embodiments, the preset temperature is 800℃-1300℃, and the optimal preset temperature is 1030-1050℃, which can prevent the glass liquid from solidifying, and can also prevent the dangerous phenomenon of glass solidification and inability to discharge or uncontrolled discharge of glass, thereby improving the safety and stability of excretion.

[0059] Specifically, in some embodiments, the discharge pipe 2 is made of platinum or platinum-rhodium alloy material. The high corrosion resistance and fire resistance of the platinum or platinum-rhodium alloy material discharge pipe can reduce the corrosion by the glass liquid, increase the service life, and ensure orderly discharge.

[0060] Specifically, in some embodiments, Figure 1 and 5 As shown, the temperature adjustment structure includes a heating component 4, and the heating component 4 is connected in the discharge support shell 3, so that the heating component 4 is connected to the discharge support shell 3 by heat transfer, and the discharge support shell 3 is connected to the discharge pipe 2 by heat transfer. The heating component 4 is a heating pipe. The flow rate is controlled by adjusting the heating power of the heating pipe, that is, when the discharge amount exceeds the set flow rate at startup or during operation, the discharge flow rate is preferentially controlled by adjusting the electric heating power.

[0061] Specifically, in some embodiments, Figure 1 and 5 As shown, the discharge support housing 3 is provided with a mounting inner cavity 31 and an adjusting hole 33 which are connected to each other; the adjusting hole 33 is connected to the opening 30 and / or the adjusting hole 33 is connected to the placement inner cavity 34; the temperature adjustment structure further includes a compressed air component 32, which is used to deliver compressed air to the mounting inner cavity 31 or extract air from the mounting inner cavity 31, and adjust the temperature of the discharge support housing 3 through the adjusting hole 33. The flow rate is controlled by adjusting the compressed air, that is, when the discharge amount exceeds the set flow rate and the heating wire is turned off, the discharge flow rate is controlled by adjusting the cooling air flow rate.

[0062] When the air of the compressed air component 32 enters the installation inner cavity 31 , the temperature of the installation inner cavity 31 will drop, thereby cooling the discharge pipe 2 .

[0063] Specifically, in some embodiments, Figure 1 and 5 As shown, the temperature adjustment structure further includes a cooling component 5, which is disposed around the outer wall of the discharge support shell 3. The cooling component 5 is a water cooling coil, which is disposed around the outer wall of the discharge support shell 3; the water cooling coil is made of stainless steel, and the number of water cooling coils can be 1-20 layers; the temperature of the outer wall of the control barrel can be effectively reduced, and the service life of the discharger can be extended.

[0064] Specifically, in some embodiments, Figure 1 -4, the discharge pipe 2 includes a main body 21 and a discharge pipe body 24, the main body 21 is connected to the liquid outlet at the bottom of the kiln pool; the first end of the discharge pipe body 24 is connected and communicated with the liquid outlet end of the main body 21; the second end of the discharge pipe body 24 passes through the opening 30 and extends to the placement cavity 34; the width value of the opening 30 is greater than the width value of the discharge pipe body 24.

[0065] The segmented discharge pipe 2 can effectively ensure the conveying stability at the conveying section at the bottom of the kiln pool and the conveying end of the discharge support shell 3, reduce liquid leakage to the discharge pipe 2 and the discharge support shell 3, thereby improving the use stability and extending its service life.

[0066] Specifically, in some embodiments, Figure 1As shown, the length L2 of the discharge pipe body 24 in the conveying direction is greater than the thickness L1 of the discharge support shell 3 at the opening 30; wherein, the length L2 minus the thickness L1 is greater than or equal to 10 mm. The longer length of the discharge pipe body 24 can prevent the discharged glass from adhering to the opening 30 or the inner wall of the discharge support shell 31 to cause overhead pollution, thereby affecting the service life of the discharge support shell 3, thereby improving the safety of use.

[0067] Specifically, in some embodiments, Figure 2 As shown in FIG. 4 , the furnace pool bottom is a refractory body 1, a mounting channel 11 is provided in the refractory body 1, and the main pipe 21 abuts against the inner wall of the mounting channel 11;

[0068] In addition, at least two installation grooves 12 are provided on the refractory body 1, and the installation grooves 12 are respectively located at the entrance and exit of the installation channel 11; at least two sealing protrusions 22 are provided on the outer wall of the main pipe 21, and the sealing protrusions 22 abut against the inner wall of the installation grooves 12.

[0069] Among them, the refractory body 1 is made of refractory bricks, that is, the upper edge, installation channel and lower edge of the refractory bricks are all wrapped with platinum, which can effectively prevent the erosion of the refractory material by the glass liquid.

[0070] Specifically, in some embodiments, Figure 1 and 3 As shown, the temperature adjustment structure includes a temperature detection component 201, and the temperature detection component 201 is arranged on the outer surface of the discharge pipe 2. The temperature detection component 201 is a temperature sensor or a thermocouple; the temperature sensor or the thermocouple is used to monitor the glass temperature in the platinum discharge pipe, thereby helping to control the flow rate.

[0071] Startup and operation of the discharge device: When starting, turn off the cooling component 5, turn off the cooling water outside the control discharge support shell 3, turn on the heating component 4 inside the control discharge support shell 3 to heat, so that the temperature of the platinum discharge pipe rises to the flow temperature (between 800℃ and 1300℃), and after the discharge starts, start the cooling water of the cooling component 5 outside the heating discharge support shell 3 to control the flow according to the discharge amount. The cooling water is no longer adjusted during normal operation. During normal production, the flow rate is adjusted by automatically adjusting the power of the heating component 4. When the electric heating power reaches the maximum or minimum, the cooling air volume of the compressed air component 32 is fine-tuned to control the flow rate, and the electric heating power is within the adjustable range.

Since the discharge method for glass preparation adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
