Description

Technical Field

[0001] The invention relates to the technical field of chemical production, in particular to a high-boiling silicone oil hydrolysis production line. Background Art

[0002] High-boiling silicone oil is an important chemical product. The existing production method is to mix trimethyl monochlorosilane and organosilicone chlorosilane high-boiling products (hereinafter referred to as high-boiling products) in a certain proportion in a storage tank in the raw material tank area, and then transfer them to the high-boiling high-level tank in the workshop with a transfer pump. A certain amount of clean water is added to the hydrolysis reactor under the high-level tank, the reactor stirrer is turned on, and the high-boiling products in the high-level tank are slowly added dropwise to the reactor. The high-boiling products react with water to produce hydrolyzed silicone oil and produce hydrochloric acid as a by-product. After the addition is completed, stirring is stopped, and after standing for 30-60 minutes, the lower layer of hydrochloric acid in the kettle is discharged into the collection pool, and the upper layer of silicone oil is stored in a ton barrel, and then transferred to the neutralization kettle and soda ash is added for neutralization. After neutralization, the oil and salt are separated to obtain the silicone oil product.

[0003] However, the neutralized salt-oil mixture needs to be packed again in turnover barrels and left to stand for 24-48 hours before the silicone oil and salt can be separated. This method of oil-salt separation not only increases the turnover times but also takes too long, greatly reducing the production efficiency of silicone oil.

[0004] In view of this, the present invention proposes a high-boiling silicone oil hydrolysis production line to solve the above technical problems. Summary of the Invention

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The embodiments of the present invention provide a high-boiling silicone oil hydrolysis production line, which solves the technical problems that the existing neutralized oil-salt mixture needs to be left to stand for 24-48 hours to separate the silicone oil from the salt, and the upper silicone oil layer and the lower salt layer are usually separated by liquid separation, which easily causes some salt to be entrained in the silicone oil, resulting in a decrease in the purity of the silicone oil. At the same time, the long-term standing treatment leads to low production efficiency.

[0042] The technical solution in the embodiment of the present invention is to solve the above technical problems. The overall idea is as follows: while the motor drives the intermediate tube to rotate, the alkali liquid in the primary alkali liquid cylinder and the secondary alkali liquid cylinder are respectively transported to the intermediate tube, and the alkali liquid is evenly sprayed out through the liquid spray plate above the intermediate tube, and the partition plate provided at the upper end of the barrel is evenly provided with leakage holes, so that the hydrolyzed silicone oil can slowly fall, thereby allowing the alkali liquid to fully contact the hydrolyzed silicone oil. Compared with the prior art of dripping alkali liquid, the present invention can improve the contact effect between the alkali liquid and the hydrolyzed silicone oil, thereby improving the neutralization effect and increasing the amount of silicone oil precipitation;

[0043] The neutralized oil-salt mixture falls onto the primary filter, which performs a preliminary filtration on the oil-salt mixture, so that large salt particles are shoveled into the upper receiving trough by the shovel plate, and the small salt particles and silicone oil mixture fall onto the secondary filter through the discharge port below the upper receiving trough. After being filtered again by the secondary filter, the small salt particles are shoveled into the lower receiving trough, and the silicone oil is discharged from the barrel through the discharge pipe under the secondary filter. Compared with the prior art, the present invention can separate the silicone oil and salt during the neutralization process, eliminating the need for standing time, improving the purity of the silicone oil and improving production efficiency at the same time.

[0044] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

The lower end of the barrel with a conical structure is connected to a discharge pipe 13, and the right side of the upper end face of the barrel 1 is connected to a feed pipe 11. A partition 12 is fixedly connected to the upper inner side surface of the barrel 1, and leakage holes are evenly opened on the partition 12. A neutralization mechanism 2 is provided below the partition 12.

[0047] During operation, the hydrolyzed silicone oil is fed into the barrel 1 through the feed pipe 11. Since leakage holes are evenly opened on the partition 12, the hydrolyzed silicone oil can fall slowly and evenly. Under the action of the neutralization mechanism 2, the hydrolyzed silicone oil and the alkali solution are fully mixed evenly, thereby improving the neutralization effect, eliminating the step of transferring it to a turnover barrel for static rest, and improving production efficiency.

[0048] As an embodiment of the present invention, Figure 3 、 Figure 5 and Figure 6As shown, a neutralization mechanism 2 is provided below the partition 12, and the neutralization mechanism 2 includes a rotating shaft 211, an intermediate tube 22 and a rotary joint 27. The intermediate tube 22 is located at the center of the barrel 1 below the partition 12, and its lower end is fixedly connected to the lower end face of the discharge pipe 13 through the rotary joint 27. The lower end of the rotating shaft 211 is fixedly connected to the upper end face of the intermediate tube 22, and its upper end passes through the partition 12 to the top of the barrel 1 and is rotatably connected to the center position of the upper end face of the barrel 1. A plurality of conical structure spray plates 221 are vertically and equidistantly fixedly connected above the annular outer surface of the intermediate tube 22, and the spray plates 221 are provided below. The slow flow plate 222 has a funnel-shaped structure, and the side of the slow flow plate 222 away from the intermediate tube 22 is fixedly connected to the inner wall of the barrel 1. The interior of the liquid spraying plate 221 is a cavity structure, and the upper side thereof is evenly provided with spray holes 2211. The outer edges of the left and right sides of the lower end of the liquid spraying plate 221 are fixedly connected with scrapers 2221 through connecting rods, and the scrapers 2221 are in contact with the upper side of the slow flow plate 222. The left side of the barrel 1 is symmetrically fixedly connected with the secondary alkali liquid cylinder 24 and the primary alkali liquid cylinder 23, and a three-way joint 224 is provided between the secondary alkali liquid cylinder 24 and the primary alkali liquid cylinder 23. The upper end of the three-way joint 224 is connected to the upper The liquid outlet pipe is connected to the lower end face of the secondary alkali liquid cylinder 24, and its lower end is connected to the upper end face of the primary alkali liquid cylinder 23 through the lower liquid outlet pipe. The left side of the three-way joint 224 is connected to the rotary joint 27 at the lower end of the intermediate tube 22 through the infusion pipe 223. The upper end of the left side face of the primary alkali liquid cylinder 23 and the lower end of the left side face of the secondary alkali liquid cylinder 24 are respectively connected to the liquid inlet pipe. A reciprocating screw rod 25 is provided at the center position of the interior of the secondary alkali liquid cylinder 24. The lower end of the reciprocating screw rod 25 passes through the interior of the primary alkali liquid cylinder 23 and is rotatably connected to the lower end face of the primary alkali liquid cylinder 23. The reciprocating screw rod 25 at the upper position of the interior of the secondary alkali liquid cylinder 24 and the primary alkali liquid cylinder 23 is connected. The rods 25 are respectively connected to pistons 26 through a spiral transmission, and a sealing ring is fixedly connected to the contact position between the piston 26 and the reciprocating screw rod 25. The upper end of the reciprocating screw rod 25 passes through the top of the secondary alkali liquid cylinder 24, and the upper end of the reciprocating screw rod 25 is fixedly connected to a primary pulley 251, and the primary pulley 251 is rotatably connected to a secondary pulley 252 through a belt, and the secondary pulley 252 is fixedly connected to the upper end of the rotating shaft 211. The rotating shaft 211 is provided with a motor 21, and the motor 21 is fixedly connected to the upper end surface of the barrel 1 through a frame, and the output shaft of the motor 21 is fixedly connected to the center position of the upper end surface of the secondary pulley 252.

[0049] During operation, the starting motor 21 drives the secondary pulley 252 to rotate. Since the secondary pulley 252 is connected to the primary pulley 251 through a belt rotation, the upper end of the reciprocating screw rod 25 is fixedly connected to the primary pulley 251, thereby driving the reciprocating screw rod 25 to rotate. Since the pistons 26 in the primary alkali liquid cylinder 23 and the secondary alkali liquid cylinder 24 are both spirally connected to the reciprocating screw rod 25, and the left and right sides of the piston 26 are fixedly connected to the limit blocks, the inner side walls of the primary alkali liquid cylinder 23 and the secondary alkali liquid cylinder 24 are provided with limit grooves that match the limit blocks, thereby driving the piston 26 to move downward. At this time, the one-way valve in the upper liquid inlet pipe at the lower end of the left side of the secondary alkali liquid cylinder 24 is closed, and the upper end of the left side of the primary alkali liquid cylinder 23 is closed. The one-way valve in the lower liquid inlet pipe is opened, the one-way valve in the upper liquid outlet pipe at the upper end of the three-way joint 224 is opened, and the one-way valve in the lower liquid outlet pipe at the lower end of the three-way joint 224 is closed, so that the soda ash solution in the secondary alkali liquid cylinder 24 enters the liquid infusion pipe 223 through the three-way joint 224 until it is transported to the intermediate pipe 22, and the piston 26 in the primary alkali liquid cylinder 23 replenishes the soda ash solution into the primary alkali liquid cylinder 23 through the lower liquid inlet pipe. Since the interior of the spray plate 221 is a cavity structure and is connected to the intermediate pipe 22, the soda ash solution entering the intermediate pipe 22 is divided into several spray plates 221. As the piston 26 continues to move downward, the soda ash solution in the spray plate 221 is continuously and evenly discharged through the spray holes 221. 1 is sprayed out and neutralized with the hydrolyzed silicone oil that continuously and evenly falls through the partition 12. Since the upper end of the intermediate tube 22 is fixedly connected to the secondary pulley 252 through the rotating shaft 211, the intermediate tube 22 is driven to rotate continuously. The scrapers 2221 are fixedly connected to the outer edges of the left and right sides of the lower end of the spray plate 221 through connecting rods. The scrapers 2221 continuously scrape the silicone oil on the upper end of the slow flow plate 222 to the next layer. Under the blocking effect of the slow flow plate 222, the falling speed of the silicone oil slows down, thereby extending the reaction time with the soda ash solution, making the hydrolyzed silicone oil and the soda ash solution more fully mixed, improving the neutralization effect, and increasing the amount of silicone oil precipitated. When the piston 26 in the primary alkali liquid cylinder 23 moves to the lower end of the reciprocating screw 25 When the piston 26 starts to move back, the one-way valve in the upper liquid inlet pipe at the lower end of the left side of the secondary alkali liquid cylinder 24 is opened, the one-way valve in the lower liquid inlet pipe at the upper end of the left side of the primary alkali liquid cylinder 23 is closed, the one-way valve in the upper liquid outlet pipe at the upper end of the three-way joint 224 is closed, and the one-way valve in the lower liquid outlet pipe at the lower end of the three-way joint 224 is opened, so that the soda ash solution in the primary alkali liquid cylinder 23 enters the infusion pipe 223 through the three-way joint 224, and the secondary alkali liquid cylinder 24 is replenished with soda ash solution through the upper liquid inlet pipe. The primary alkali liquid cylinder 23 and the secondary alkali liquid cylinder 24 alternately convey the soda ash solution, so that the soda ash solution can be continuously sprayed out of the spray plate 221, thereby realizing continuous production and improving production efficiency.

[0050] As an embodiment of the present invention, Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown, a separation mechanism 3 is provided at the center position of the barrel 1, and the separation mechanism 3 includes a primary filter screen 31, a secondary filter screen 32 and a fixed ring 33. The primary filter screen 31 and the secondary filter screen 32 are arranged below the slow flow plate 222 on the lowermost side, and the primary filter screen 31 and the secondary filter screen 32 are both conical structures. The outer edges of the lower ends of the primary filter screen 31 and the secondary filter screen 32 are respectively fixedly connected to the inner side surface of the barrel 1, and the upper ends of the primary filter screen 31 and the secondary filter screen 32 are respectively fixedly connected to the annular outer surface of the fixing ring 33, and the fixing ring 33 is rotatably connected to the intermediate tube 22. A sleeve 34 is fixedly connected to the outer surface of the intermediate tube 22 between the two fixing rings 33, and a plurality of cylindrical holes 341 are equidistantly provided on the annular surfaces at the upper and lower ends of the sleeve 34, and punches 342 are elastically connected to the cylindrical holes 341 through springs. The head has a hemispherical structure, and a plurality of wedge blocks 331 are fixedly connected to the corresponding sides of the fixing ring 33 and the sleeve 34 in an annular manner at equal intervals. A shovel plate 35 is provided on the left and right sides of the upper side surfaces of the primary filter screen 31 and the secondary filter screen 32, respectively. The shovel plates 35 on the primary filter screen 31 are fixedly connected to the outer surface of the intermediate tube 22, and the shovel plates 35 on the secondary filter screen 32 are fixedly connected to the lower end of the outer surface of the sleeve 34, respectively. A through opening 43 is provided on the barrel 1 on the left and right sides of the outer edge of the lower end of the primary filter screen 31 and the secondary filter screen 32, and a material receiving trough 4 is fixedly connected to the outer side surface of the barrel 1 below the through opening 43. The outer side surface of the material receiving trough 4 has slots 41 on the upper and lower sides, a material receiving frame 42 is inserted in the slot 41, and the lower end surface of the material receiving frame 42 has a filter screen structure, and the lower end of the inner side surface of the material receiving trough 4 has a discharge port 44 that penetrates into the barrel 1.

[0051] During operation, based on the above embodiment, the neutralized oil-salt mixture first falls on the primary filter 31, and the silicone oil continues to fall onto the secondary filter 32 through the primary filter 31, and the large salt particles are blocked by the primary filter 31. Since the shovel plates 35 on the primary filter 31 are fixedly connected to the outer surface of the intermediate tube 22, the large salt particles accumulated on the primary filter 31 are shoveled to the upper side opening 43 under the drive of the intermediate tube 22, and enter the receiving trough 4 through the upper side opening 43. The material frame 42 collects large salt particles, and the silicone oil that flows down enters the barrel 1 again through the discharge port 44 at the lower end of the inner side of the upper receiving trough 4 and falls on the secondary filter 32. The silicone oil is filtered by the secondary filter 32 and discharged from the barrel 1 through the discharge pipe 13. The small salt particles are blocked by the secondary filter 32, and the shovel plate 35 on the secondary filter 32 is fixedly connected to the lower end of the sleeve 34 on the outer surface of the intermediate tube 22, thereby driving the shovel plate 35 to shovel the small salt particles on the secondary filter 32 to the position of the lower side opening 43 , enters the lower receiving trough 4 through the lower side opening 43, and the receiving frame 42 in the lower receiving trough 4 collects the small salt particles, and the silicone oil that comes down enters the barrel 1 through the discharge port 44 at the lower end of the inner side of the lower receiving trough 4 and is discharged through the discharge pipe 13. During this process, the punch 342 in the cylindrical hole 341 on the upper and lower end surfaces of the sleeve 34 is first compressed into the cylindrical hole 341 when passing through the wedge block 331 on the fixing ring 33, and then quickly pops out, thereby continuously generating vibration force on the primary filter 31 and the secondary filter 32 , so that the salt particles attached to the primary filter screen 31 and the secondary filter screen 32 can slide into the material receiving trough 4 to avoid the mesh being blocked, and the material receiving frame 42 in the material receiving trough 4 is designed with a double-layer structure, so that when the upper material receiving frame 42 is full, it can be pulled out through the slot 41. At this time, the lower material receiving frame 42 can replace the upper material receiving frame 42 to continue collecting salt particles, avoiding the situation where the salt particles that have not been filtered and collected enter the barrel 1 again after the material receiving frame 42 is taken out of the material receiving trough 4 and affect the purity of the silicone oil, thereby improving the purity of the silicone oil and improving production efficiency.

[0052] Working principle: The hydrolyzed silicone oil is fed into the barrel 1 through the feed pipe 11. Since the partition 12 is evenly provided with leakage holes, the hydrolyzed silicone oil can fall slowly and evenly. The starting motor 21 drives the secondary pulley 252 to rotate. Since the secondary pulley 252 is connected to the primary pulley 251 through a belt rotation, the upper end of the reciprocating screw 25 is fixedly connected to the primary pulley 251, thereby driving the reciprocating screw 25 to rotate. Since the pistons 26 in the primary alkali liquid cylinder 23 and the secondary alkali liquid cylinder 24 are both connected to the reciprocating screw 25 through a spiral transmission, the piston 26 is driven downward. At this time, the one-way valve in the upper liquid inlet pipe at the lower end of the left side of the secondary alkali liquid cylinder 24 is closed, the one-way valve in the lower liquid inlet pipe at the upper end of the left side of the primary alkali liquid cylinder 23 is opened, and the three-way joint 224 is opened. The one-way valve in the upper liquid outlet pipe at the upper end is opened, and the one-way valve in the lower liquid outlet pipe at the lower end of the three-way joint 224 is closed, so that the soda ash solution in the secondary alkali liquid cylinder 24 enters the liquid infusion pipe 223 through the three-way joint 224 until it is transported to the intermediate pipe 22, and the piston 26 in the primary alkali liquid cylinder 23 replenishes the soda ash solution into the primary alkali liquid cylinder 23 through the lower liquid inlet pipe. Since the interior of the spray plate 221 is a cavity structure and is connected to the intermediate pipe 22, the soda ash solution entering the intermediate pipe 22 is diverted to several spray plates 221. As the piston 26 continues to move downward, the soda ash solution in the spray plate 221 is continuously and evenly sprayed out through the spray hole 2211 and neutralized with the hydrolyzed silicone oil that continuously and evenly falls through the partition 12. Since the upper end of the intermediate pipe 22 passes through The rotating shaft 211 is fixedly connected to the secondary pulley 252, thereby driving the intermediate tube 22 to rotate continuously. The scrapers 2221 are fixedly connected to the outer edges of the left and right sides of the lower end of the spray plate 221 through connecting rods. The scrapers 2221 continuously scrape the silicone oil on the upper end of the slow flow plate 222 to the next layer. Under the blocking effect of the slow flow plate 222, the falling speed of the silicone oil slows down, thereby extending the reaction time with the soda ash solution, making the hydrolyzed silicone oil and the soda ash solution mixed more fully, improving the neutralization effect, and increasing the amount of silicone oil precipitated. When the piston 26 in the primary alkali liquid cylinder 23 moves to the lower end of the reciprocating screw 25, the piston 26 starts to move back. At this time, the one-way valve in the upper liquid inlet pipe at the lower end of the left side of the secondary alkali liquid cylinder 24 is opened, and the upper end of the left side of the primary alkali liquid cylinder 23 The one-way valve in the lower liquid inlet pipe is closed, the one-way valve in the upper liquid outlet pipe at the upper end of the three-way joint 224 is closed, and the one-way valve in the lower liquid outlet pipe at the lower end of the three-way joint 224 is opened, so that the soda ash solution in the first-level alkali liquid cylinder 23 enters the infusion pipe 223 through the three-way joint 224, and the second-level alkali liquid cylinder 24 is replenished with soda ash solution through the upper liquid inlet pipe. The first-level alkali liquid cylinder 23 and the second-level alkali liquid cylinder 24 alternately transport the soda ash solution, so that the soda ash solution can be continuously sprayed out of the spray plate 221, realizing continuous production and improving production efficiency. The neutralized oil-salt mixture first falls on the first-level filter screen 31, and the silicone oil continues to fall onto the second-level filter screen 32 through the first-level filter screen 31. Large particles of salt are blocked by the first-level filter screen 31.Since the shovel plates 35 on the primary filter 31 are fixedly connected to the outer surface of the intermediate tube 22, the large salt particles accumulated on the primary filter 31 are shoveled down to the upper opening 43 by the drive of the intermediate tube 22, and enter the receiving trough 4 through the upper opening 43. The receiving frame 42 in the receiving trough 4 collects the large salt particles, and the silicone oil that comes down enters the barrel 1 again through the discharge port 44 at the lower end of the inner side of the upper receiving trough 4 and falls on the secondary filter 32. After the silicone oil is filtered by the secondary filter 32, it is discharged from the barrel 1 through the discharge pipe 13. The small particles of salt are blocked by the secondary filter 32. The shovel plate 35 on the secondary filter 32 is fixedly connected to the lower end of the sleeve 34 on the outer surface of the intermediate tube 22, thereby driving the shovel plate 35 to shovel the small particles of salt on the secondary filter 32 to the position of the lower side opening 43, and enter the lower side receiving trough 4 through the lower side opening 43. The receiving frame 42 in the lower side receiving trough 4 collects the small particles of salt. , the silicone oil flows down and enters the barrel 1 through the discharge port 44 at the lower end of the inner side of the lower receiving trough 4 and is discharged through the discharge pipe 13. During this process, the punches 342 in the cylindrical holes 341 on the upper and lower ends of the sleeve 34 are first compressed into the cylindrical holes 341 when passing through the wedge blocks 331 on the fixing ring 33, and then quickly pop out, thereby continuously generating vibration force on the primary filter 31 and the secondary filter 32, so that the punches 342 attached to the primary filter 31 and the secondary filter 32 are 2 can slide into the receiving trough 4 to prevent the mesh from being blocked. The receiving frame 42 in the receiving trough 4 has a double-layer structure design. When the upper receiving frame 42 is full, it can be pulled out through the notch 41. At this time, the lower receiving frame 42 can replace the upper receiving frame 42 to continue collecting salt particles. After the receiving frame 42 is taken out of the receiving trough 4, the unfiltered and collected salt particles are prevented from entering the barrel 1 again after being taken out of the receiving trough 4, thereby improving the purity of the silicone oil and improving production efficiency.
