A boron oxide kiln with strip discharge

Abstract

This invention discloses a boron oxide kiln with strip discharge, relating to the field of boron oxide production technology, including a heat preservation device, a heat homogenizing device, an observation device, and a discharge device. A bidirectional electric actuator drives two retractable supports to slide inwards. The retractable supports, through a retractable sliding rod, drive a retractable sliding plate and a discharge roller to slide inwards. The discharge roller and the retractable sliding plate limit the opening angle of the first and second compliant plates, thereby limiting the discharge speed and thickness of the boron oxide. When the shielding cover is manually rotated, the linkage column on the shielding cover contacts the side of the observation block. At this time, the linkage column drives the connecting sleeve to rotate through the observation block, realizing the disassembly and installation of the refractory sleeve. When the shielding cover is manually pulled, the shielding cover drives the refractory plunger to be pulled out from the refractory sleeve, realizing the observation function of the inside of the heat preservation device.

Description

Technical Field

[0001] This invention relates to the field of boron oxide production technology, and in particular to a boron oxide kiln with strip discharge. Background Technology

[0002] In the process of making high borosilicate glass, boric acid is usually poured into a high-temperature melting furnace first, so that the boric acid is dehydrated at high temperature and converted into molten boron oxide. Then the boron oxide is extruded in strip form into a subsequent pulverizer and crushed into powder, which becomes the raw material for making high borosilicate glass.

[0003] In existing boron oxide kilns, the closed nature of the blast furnace during production makes it impossible to observe the flame or heating conditions. The limited number of temperature sensors is insufficient for comprehensive temperature monitoring of the large furnace. Furthermore, the lack of heat homogenization measures during raw material heating leads to uneven localized overheating of the boron oxide, resulting in varying degrees of dehydration. Existing kilns also cannot control the thickness and cooling rate of the boron oxide at the outlet, causing internal stress due to uneven thickness and poor cooling, which negatively impacts subsequent processes. Therefore, a boron oxide kiln with adjustable flame and heating conditions, uniform stirring and heating of the raw materials, and control over the thickness and cooling rate of the boron oxide at the outlet is needed to address the shortcomings of existing kilns. Summary of the Invention

The discharge roller and the retracting slide plate will limit the opening angle of the first compliant plate and the second compliant plate, thereby limiting the discharge speed and discharge thickness of boron oxide; (3) When the cover is manually rotated, the linkage column on the cover will contact the side of the observation block. At this time, the linkage column drives the connecting sleeve to rotate through the observation block to achieve the disassembly and installation of the refractory sleeve.

[0041] Working principle of the invention: Figure 1 The invention provides the usage methods and corresponding scenarios. The attitude control of the boron oxide production process is determined by the heat preservation device 1, the heat equalization device 2, and the discharge device 4. The attitude of the heat preservation device 1 is determined by the heat equalization device 2, and the attitude of the discharge device 4 is determined by the heat equalization device 2. Therefore, the heat equalization device 2 is the core of the masonry curing process.

[0042] Taking a preferred embodiment as an example, such as Figure 2 , Figure 3 , Figure 4 , Figure 10 , Figure 11 and Figure 12 As shown, gaseous fuel is injected into the gas storage pipe 106. The gaseous fuel in the gas storage pipe 106 is then sprayed through the combustion nozzle 104 in the refractory base 103 between the refractory lining 102 and the refractory cover 105. An electric lighter on the combustion nozzle 104 ignites the gaseous fuel between the refractory lining 102 and the refractory cover 105. The heat from the combustion is then transferred through the refractory cover 105 to the boric acid material inside the refractory cover 105. The boric acid then decomposes into molten boron oxide, water, and oxygen within the refractory cover 105. Subsequently, the discharge electric push rod 107 drives the discharge bracket. 401 and the discharge slide 408 slide downwards. The discharge slide 408 drives the discharge sleeve 403 to slide downwards between the outlet sleeve 108 and the pressure column body 111 of the outlet pressure column 110. When the discharge sleeve 403 slides downwards a certain distance, the inclined channel 112 on the pressure column body 111 will connect with the space between the outlet sleeve 108 and the pressure column body 111. Subsequently, the boron oxide in the refractory cover 105 will flow into the space between the outlet sleeve 108 and the pressure column body 111 through the gap on the side of the outlet baffle 109, and then flow into the outlet sleeve 108 and the pressure column body 111 through the inclined channel 112 and the vertical channel 113. The boron oxide is initially fed into the sleeve 403. Then, the discharge electric push rod 107 drives the discharge bracket 401 and discharge slide 408 to slide upwards at the lower end of the discharge base 402. The discharge slide 408 drives the discharge sleeve 403 to slide upwards. When the discharge sleeve 403 again blocks the upper end of the inclined channel 112, the outlet pressure column 110 will press the boron oxide in the discharge sleeve 403 downwards. At this time, the first compliant plate 412 and the second compliant plate 413 on the support plate 414 will be pressed downwards and swing, causing the upper end of the frame body 411 to open. Subsequently, the boron oxide... It will be discharged directly from the lower end of the outlet frame 410 to realize the boron oxide feeding function; during the boron oxide feeding process, the bidirectional electric push rod 409 drives the two retracting brackets 405 to slide inward. The retracting brackets 405 drive the retracting slide plate 406 and the discharge roller 407 to slide inward through the retracting slide rod 404. The discharge roller 407 and the retracting slide plate 406 will limit the opening angle of the first compliant plate 412 and the second compliant plate 413, thereby limiting the boron oxide discharge speed and discharge thickness; the heat insulation shell 101 is used to prevent heat leakage; the feed port 205 is used for the pouring of boric acid.

[0043] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, during the continuous heating of boron oxide, the motor 203 on the heat insulation shell 202 first drives the first pulley 204 on the heat-spreading base 201 to rotate. The first pulley 204 drives the second pulley 207 to rotate via the belt 206. At this time, the first pulley 204 and the second pulley 207 respectively drive the mixing turntables 212 of the two mixing components 208 to rotate. The mixing turntables 212 drive the mixing support 211 to rotate. When the mixing support 211 approaches the inner wall of the refractory cover 105, the mixing roller 210 will contact the inner wall of the refractory cover 105 and roll, and then the mixing... Roller 210 drives the mixing block 209 to rotate. At this time, the mixing block 209 first drives the flexible swing arm 217 to swing to the side of the auxiliary support 216. Then, the mixing block 209 drives the mixing slider 214 to slide to the side of the auxiliary support 216 and the temperature-conducting stirring rod 215 to slide towards the mixing turntable 212, causing the notch at the upper end of the mixing support 211 to be exposed. This notch then pushes the mixing block 209 upwards, allowing it to bypass the obstruction of the mixing support 211 and continue rotating. The rotation of the flexible swing arm 217... The lateral movement of the heat-conducting stirring rod 215 disturbs the boron oxide on the inner wall of the refractory cover 105, causing a continuous flow and exchange of boron oxide between the inner wall and the center of the refractory cover 105, thus preventing local temperatures from becoming too low or too high. When the heating support 211 moves away from the inner wall of the refractory cover 105, the heating roller 210 disengages from the inner wall of the refractory cover 105, and the heating support 211 drives the flexible swing rod 217 and the heat-conducting stirring rod 215 to rotate synchronously, thus stirring the boron oxide at the center of the refractory cover 105 and promoting the reaction. When the shielding cover 304 of the observation device 3 is manually rotated, the linkage column 307 on the linkage cover 308 will contact the side of the observation block 303. At this time, the linkage column 307 drives the connecting sleeve 302 to rotate through the observation block 303, so as to realize the disassembly and installation of the refractory sleeve 301. When the shielding cover 304 is manually pulled, the pull ring 309 will drive the refractory plunger 306 to be pulled out from the refractory sleeve 301, so as to realize the observation function of the inside of the heat preservation device 1. The heat-resistant spring 213 is used for the rebound of the heating slider 214. The elastic pull band 305 is used for the rebound of the refractory plunger 306.
