Description

Technical Field

[0001] The invention belongs to the technical field of slurry treatment equipment, in particular to a silane gas production slurry treatment process. Background Art

[0002] As a key electronic specialty gas, silane gas plays an indispensable role in many high-tech fields such as semiconductors, solar cells, and flat panel displays. At present, the main methods for industrially producing silane gas include the silicon-magnesium alloy method and the disproportionation method. However, no matter which production method is adopted, a certain amount of slurry will be generated. The slurry needs to be processed through some processing equipment. One of them is to filter it through a vacuum drum filter. The metal impurities are reduced from the original 100,000 ppbw to about 10,000 ppbw after treatment, which greatly reduces the metal impurities and then enters the next process for treatment.

[0003] In the prior art, vacuum drum filters use negative pressure as the driving force for filtration. During the filtration operation, a negative pressure environment is formed on one side of the filter surface through the vacuum system, resulting in a pressure difference on both sides of the filter cloth. Under the action of the pressure difference, the liquid of the suspension to be filtered passes through the filter cloth and is sucked into the drum and then discharged to the outside, while the solid particles are retained on the outer surface of the filter cloth, thereby achieving solid-liquid separation. After the slurry adheres to the outer wall of the filter cloth, the liquid is sucked into the drum by the negative pressure, so that the slurry attached to the outer surface of the filter cloth is dehydrated and then scraped off by a scraper. However, the adhesion between some more viscous slurries and the filter cloth increases when passing through the scraper, making it difficult to scrape them off, affecting the use of the equipment. Moreover, if the liquid in the slurry is only sucked away and removed under negative pressure, some thicker slurries on the outer surface of the filter cloth are prone to insufficient liquid suction, resulting in unsatisfactory liquid removal effect. In the subsequent process, dehydration equipment needs to be added to remove the liquid in the slurry again, which increases the use cost and time. For this reason, a silane gas production slurry treatment process is proposed. Summary of the Invention

[0039] S2.

[0048] Example 2

[0049] Based on Example 1, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The heating and flattening mechanism also includes an adjustment component for adjusting the height of the hollow plate 200 and the hollow pressing roller 201. The adjustment component includes a top block 203 fixed to the top of the side frame 202. Adjustment screws 206 are fixedly provided on the top of both ends of the hollow plate 200. The top of the adjustment screw 206 passes through the interior of the top block 203, and the outside of the adjustment screw 206 is connected to two sets of first spiral rings by threads.

[0050] An extrusion piece is provided between the hollow plate 200 and the upper bearing 208. The extrusion piece includes a stud 302 fixed to the top of the upper bearing 208 and a mounting block 213 fixed to both ends of the hollow plate 200. The top of the limit rod passes through the interior of the mounting block 213.

[0051] Two sets of movable plates 211 are slidably provided inside the mounting block 213. The bottom of the movable plates 211 is fixedly connected to the upper bearing 208. A limit rod is fixed to the outer wall of the upper bearing 208, and the top of the limit rod passes through the interior of the mounting block 213. A spring 215 is fixedly provided between the top of the mounting block 213 and the bottom of the movable plates 211.

[0052] The interior of the movable plate 211 is connected to a screw rod 214 through a thread, and the top of the screw rod 214 extends to the outside of the top of the mounting block 213. A nut block 216 is provided on the outside of the screw rod 214. A limit plate is fixedly provided on the side of the nut block 216. A sliding groove for the limit plate to move up and down is provided on the side of the movable plate 211. A first fluid slip ring 209 is provided on the outside of the right tube 210. A return pipe 212 is fixedly provided between the top of the first fluid slip ring 209 and the hollow plate 200. After the hot air enters the interior of the hollow pressure roller 201, it will be discharged into the first fluid slip ring 209, and then The hot air also enters the hollow plate 200 through the return pipe 212, so that the exhausted hot air can be fully utilized without waste. When the spring 215 becomes insufficient in elasticity after being used for a long time, the bottom of the screw rod 214 is rotated. At this time, the rotating screw rod 214 drives the external nut block 216 to move upward, and the nut block 216 squeezes the spring 215, which can increase the elasticity of the spring 215. The elasticity of the spring 215 can be adjusted to avoid affecting the contact effect between the hollow pressure roller 201 and the slurry below. In addition, by adjusting the elasticity, the frequency of replacing the spring 215 can be reduced, thereby reducing the replacement cost.

[0053] The present invention uses a designed heating and flattening mechanism to flatten the slurry on the outer surface of the filter cloth 103 through the hollow pressing roller 201 during use, compressing and thinning the thicker slurry layer, squeezing out water, and keeping the slurry thickness on the outer surface of the filter cloth 103 consistent. It can also increase the path efficiency of the liquid passing through the filter cloth 103, thereby improving the dehydration effect. At the same time, a heating medium is introduced into the hollow pressing roller 201, and the heat conduction of the hollow pressing roller 201 is used to reduce the viscosity of the slurry, reduce the adhesion to the filter cloth 103, increase the degree of subsequent scraping by the scraper 104, and reduce the dependence on the subsequent use of other dehydration equipment.

[0054] In summary, wastewater enters the wastewater tank 100, and then the drive motor 101 is started. The working end of the drive motor 101 rotates to indirectly drive the drum body 102 and the filter cloth 103 outside it to rotate, and then the slurry in the wastewater tank 100 is attached to the outer surface of the filter cloth 103. At the same time, the installation motor 204 and the hot air blower located outside the equipment are turned on. The working end of the installation motor 204 rotates to indirectly drive the hollow pressing roller 201 to rotate, flattening the slurry on the outer surface of the filter cloth 103 into a slurry cake, so that the slurry on the outer surface of the filter cloth 103 is evenly distributed. As the filter cloth 103 rotates, the slurry enters the position above the drum body 102, and the hot air generated by the hot air blower enters the hollow roller through the right pipe 207 and the right pipe 210. Inside the pressing roller 201, the hot air heats the hollow pressing roller 201, and then the outer wall of the hollow pressing roller 201 with a certain amount of heat contacts the slurry cake, and conducts the heat into the slurry cake, heating and softening the sticky slurry cake, thereby reducing the viscosity of the slurry cake. At the same time, the hot air entering the right connecting pipe 207 can also enter the hollow plate 200 through the hose, and then the hot air is ejected downward from the multiple groups of nozzles 205 at the bottom. The hot air can not only blow away some broken slurry attached to the outer edge of the rotating hollow pressing roller 201, but also heat and soften the slurry below by the hot air, thereby reducing the viscosity of the slurry. It can not only flatten the slurry to make it evenly distributed, but also heat and soften the sticky slurry to reduce its viscosity.

[0055] Before the slurry is flattened by the hollow pressure roller 201, the distance between the hollow pressure roller 201 and the slurry is adjusted so that the thickness of the slurry flattened is as consistent as possible. When adjusting, the two sets of first spiral rings on the outside of the adjusting screw 206 are rotated in opposite directions to loosen them, and then the adjusting screw 206 is moved upward or downward as needed, driving the hollow plate 200 below and the hollow pressure roller 201 to move accordingly. When the adjustment is completed, the two sets of first spiral rings are rotated in opposite directions and tightened to adjust the distance between the hollow pressure roller 201 and the slurry. Then, when the hollow pressure roller 201 is flattening the slurry, the two sets of springs 215 on the mounting block 213 cause the movable plate 211 to generate a downward squeezing force, so that the movable plate 211, the upper bearing 208 and the hollow pressure roller 201 all have a downward squeezing force, thereby increasing the flattening effect of the hollow pressure roller 201 on the slurry.

[0056] Example 3

[0057] Based on Example 2, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The outside of the drum body 102 is also provided with an auxiliary unloading member, which includes a hollow heating tube 301 rotatably arranged on the outside of the filter cloth 103. A knife holder 304 is provided on the outside of the hollow heating tube 301 for cutting the slurry cake attached to the outer wall of the filter cloth 103 into a suitable size.

[0058] The knife pressing frame 304 is provided with a plurality of blowing holes 307. The two ends of the hollow heating tube 301 are respectively provided with a left rod and a right connecting tube. The outer sides of the left rod and the right connecting tube are both sleeved with a lower bearing 303. An L-shaped plate is fixedly provided on the top of the lower bearing 303. An arc-shaped back-blowing plate 300 is fixedly provided between the two groups of L-shaped plates. The arc-shaped back-blowing plate 300 is fixed on the outer wall of the lower bearing 303. When the plurality of blowing holes 307 on the knife pressing frame 304 blow hot air into the bottom slurry cake through the arc-shaped back-blowing plate 300, the plurality of blowing holes 307 on the top of the knife pressing frame 304 will also blow hot air outwards, causing waves. The hot air blown back through the arc-shaped back-blowing plate 300 is blown into the upper arc-shaped back-blowing plate 300, and the arc-shaped structure causes the hot air to be reversed and blown downward. At this time, the reverse-blown hot air is blown back to the surface of the slurry cake and the outer wall of the hollow heating tube 301 and the press knife holder 304, which can blow out even small slurry attached to the outer wall of the hollow heating tube 301 and the press knife holder 304. At the same time, the hot air blown to the surface of the slurry cake can also heat the slurry cake and reduce its viscosity. The hot air blown out through the blowing hole 307 above the press knife holder 304 can be effectively and fully utilized to avoid waste of production.

[0059] A stud 302 is slidably provided on the side frame 202. Two sets of second spiral rings are threadedly connected to the outside of the stud 302. The top of the stud 302 is fixedly connected to the bottom of the lower bearing 303. A first rotary joint 306 is provided at the end of the right connecting pipe. A telescopic tube 305 is provided between the first rotary joint 306 and the right connecting pipe 207.

[0060] The present invention is designed with auxiliary unloading parts. When in use, the pressure knife holder 304 outside the hollow heating tube 301 cuts the continuous slurry cake into suitable small pieces, avoiding the unloading of large pieces of slurry due to their own weight or viscosity, and reducing the resistance of the scraper 104 to scraping. In addition, the heat is transferred to the surface of the slurry cake through the hollow heating tube 301 and the pressure knife holder 304 outside it, which can further soften the sticky slurry cake and reduce its viscosity. Hot air is blown into the interior of the slurry cake through the multiple groups of blowing holes 307 on the pressure knife holder 304, which can not only soften the interior of the slurry cake by hot air and reduce the viscosity of the slurry cake, but also loosen the interior of the slurry cake by hot air, reduce the adhesion between the slurry cake and the filter cloth 103, and improve the thoroughness of subsequent unloading by the scraper 104.

[0061] In summary, during the flattening process, the hot air in the right connecting pipe 207 can also be transported to the hollow heating pipe 301 through the telescopic pipe 305, heating the hollow heating pipe 301 and the external pressure knife rack 304. At this time, the continuous and integral slurry cake on the outside of the filter cloth 103 can be cut into a suitable size by the pressure knife rack 304. At the same time, the heat of the hollow heating pipe 301 and the pressure knife rack 304 with a certain amount of heat is transferred to the contact surface with the slurry cake to further heat the slurry cake, further reducing the viscosity of the slurry cake. Moreover, the outer side of the pressure knife rack 304 can be pressed into the interior of the slurry cake, and the multiple groups of blowing holes 307 located in the pressure knife rack 304 can enter the hollow heating pipe. The hot air in 301 is blown to the inside of the slurry cake. The hot air can not only heat and soften the sticky slurry cake to reduce its viscosity, but also make the inside loose, which is convenient for subsequent scraping and unloading by the scraper 104. In addition, the distance between the hollow heating tube 301, the knife holder 304 and the slurry cake can be adjusted during or before use. When adjusting, the two sets of second spiral rings outside the stud 302 are rotated outward to loosen them, and then the stud 302 is moved upward or downward to drive the hollow heating tube 301 to move upward or downward. After the movement is completed, the two sets of second spiral rings are rotated in opposite directions and tightened to adjust.

[0062] In this embodiment, a rotating tube is provided inside the filter cloth 103, a driving motor 101 is fixedly provided on the wastewater tank 100, the working end of the driving motor 101 extends to one end of the rotating tube, a drain pipe is provided at the other end of the rotating tube, and a water inlet is provided on the back of the wastewater tank 100.

[0063] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
