A reactor for safely preparing high-viscosity hydroxyl butyl benzene latex

Abstract

A reactor for the safe preparation of high-viscosity hydroxybutyrate (HHB) latex is disclosed. This invention addresses the issue of latex adhering to the tank walls after use, requiring cleaning. While conventional cleaning methods involve filling the tank with water and stirring, which removes latex residue from the stirring rod, the strong adhesion to the inner tank walls makes water alone insufficient, leaving residue that affects subsequent mixing ratios. Furthermore, prolonged latex residue may solidify, causing clumping in the final latex. This invention utilizes a cleaning structure to clean the reactor interior while maintaining a sealed environment, preventing splashes from reaching workers' eyes or other sensitive areas. The automatic water filling mechanism eliminates manual operation, minimizing worker contact and preventing injuries during cleaning.

Description

Technical Field

[0001] This invention relates to the field of hydroxybutyrate latex technology, and particularly to a reactor for the safe preparation of high-viscosity hydroxybutyrate latex. Background Technology

[0002] Hydroxybutadiene latex is a mainstream latex with high viscosity. It is also an environmentally friendly latex and is used in many fields. A reactor is required when preparing hydroxybutadiene latex. The reactor can mix the materials required for the reaction of hydroxybutadiene latex and provide a certain temperature to enable the reaction.

[0003] After the reactor is used, a large amount of latex will adhere to the tank wall inside, which needs to be cleaned. However, the cleaning method usually involves pouring water and stirring. This method can remove the latex residue on the surface of the stirring rod, but the adhesion of the latex to the inner wall of the tank is strong, and it is difficult to clean it by water alone. Some residue may still remain after cleaning, affecting the proportions in subsequent preparations. Furthermore, if the residual latex remains in the tube for a long time, it may solidify, causing lumps to form inside the latex in the subsequent preparations. Summary of the Invention

[0004] The purpose of this invention is to provide a reactor for the safe preparation of high-viscosity hydroxybutyrate latex, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reactor for the safe preparation of high-viscosity hydroxybutyrate latex, comprising a support frame, a heating assembly fixed inside the support frame, and a reaction vessel fixed inside the heating assembly. The support frame has a cleaning structure inside. A three-way valve is fixed to the bottom of the reaction vessel, and a feed inlet is fixed to one side of the top of the reaction vessel. A stirring assembly is arranged above the reaction vessel, and a connection switching structure is installed at the bottom of the stirring assembly. A stirring frame is rotatably connected inside the reaction vessel. The cleaning structure includes a water storage tank fixed to the bottom of the support frame, a pumping assembly fixed to one side of the top of the reaction vessel, a connecting assembly fixed inside the reaction vessel, a return water pipe fixed to one side of the three-way valve, a water distribution chamber located inside the stirring frame, and several equally spaced nozzles arranged on one side of the water distribution chamber.

[0007] Furthermore, the connecting assembly includes an upper connecting box fixed to the top of the inside of the reaction vessel, and a first water inlet is provided on one side of the inside of the upper connecting box. A lower connecting box is provided at the bottom of the upper connecting box, and a connecting ring is fixed at the top of the lower connecting box. The lower connecting box is sleeved with the upper connecting box through the connecting ring. Water outlets are provided on both sides of the bottom of the lower connecting box. The lower connecting box is fixedly connected to the stirring frame.

[0008] Furthermore, the second water outlet pipe is connected to the upper connecting box through the first water inlet, and the connecting pipe is connected to the lower connecting box through the water outlet.

[0009] Furthermore, the water storage tank includes a water inlet inside it, a second water inlet on one side of the water inlet, a water filling port fixed at the top of the water storage tank, and a debris outlet fixed on one side of the water storage tank.

[0010] Furthermore, the return water pipe is connected to the water storage tank through the second water inlet, the first water inlet pipe is connected to the water storage tank through the water outlet, the bottom end of the second water inlet pipe is connected to the water storage tank, and the bottom end of the first water outlet pipe is connected to the reaction tank.

[0011] Furthermore, the connection switching structure includes a shell fixed to the top of the reaction vessel, and a connecting sleeve is movably connected to the top of the shell. The top of the connecting sleeve is fixedly connected to the output shaft of the stirring assembly. A connecting seat is movably connected to the bottom of the shell, and the bottom of the connecting seat is fixedly connected to the top of the stirring frame.

[0012] Furthermore, an electric telescopic rod is installed at the bottom inside the outer casing, and a bearing sleeve is fixed at the top of the electric telescopic rod. A connecting shaft is rotatably connected inside the bearing sleeve, and the top of the connecting shaft extends into the interior of the connecting sleeve.

[0013] Furthermore, a gear plate is fixed to the outside of the connecting shaft, a first gear is movably connected to one side inside the housing, and a second gear is provided below the first gear. One side of the first gear is fixedly connected to the input shaft of the first water inlet pipe, and the second gear is fixedly connected to the input shaft of the high-pressure water pump.

[0014] Furthermore, the gear disc and the first gear rod form a meshing connection, the bearing sleeve forms a lifting structure inside the outer shell through an electric telescopic rod, the outer diameter of the connecting shaft is slightly smaller than the inner diameter of the connecting seat, and the bottom end of the connecting shaft can be inserted into the interior of the connecting seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention proposes a reactor for the safe preparation of high-viscosity hydroxybutyrate latex. After the preparation is completed inside the reactor, it needs to be cleaned. At this time, clean water is added to the inside of the water tank through the water inlet, and the water level does not exceed the height of the debris outlet. At this time, the toothed disc is engaged with the first toothed rod. Then, the stirring assembly is started to rotate, which drives the connecting sleeve to rotate. The connecting sleeve drives the connecting shaft to rotate, which drives the toothed disc to rotate. The toothed disc drives the first toothed rod to rotate, and the first toothed rod drives the low-pressure water pump to operate. The low-pressure water pump draws water from the inside of the water tank through the first water inlet pipe. Then, the low-pressure water pump inputs water into the reaction vessel through the first water outlet pipe, and the reaction vessel can be filled with clean water. Then, the electric telescopic rod is started to pull the bearing sleeve downward. At this time, the bearing sleeve drives the bottom end of the connecting shaft to insert into the connecting seat. At the same time, the toothed disc moves downward with the connecting shaft, and the top of the toothed disc disengages from the first toothed rod. The gear plate then engages with the second gear rod below. At this time, the stirring assembly rotates, causing the connecting shaft to rotate. The connecting shaft then rotates the connecting seat, which in turn causes the stirring frame to stir and clean inside the reaction tank. Simultaneously, the connecting shaft rotates the gear plate, which in turn causes the second gear rod to rotate. The second gear rod then drives the high-pressure water pump to operate. The high-pressure water pump draws water from the storage tank through the second inlet pipe and inputs it into the upper connecting box through the second outlet pipe. The water flow inside the upper connecting box can enter the lower connecting box through the gap in the middle of the connecting ring. The lower connecting box can input water into the connecting pipe through the outlet. The lower connecting box and the upper connecting box are connected by the connecting ring, allowing the lower connecting box to supply water during rotation. The water flow enters the water distribution chamber through the connecting pipe. The water distribution chamber distributes the water flow evenly to the nozzles. The nozzles spray high-pressure water and, along with the rotation of the stirring frame, clean the inner wall of the reaction tank. This process cleans the inside of the reaction tank.

[0017] After cleaning the inside of the reaction vessel, activate the three-way valve to connect the output port of the reaction vessel with the return water pipe. Then, water containing latex will flow into the water storage tank. Because the density of latex is lower than that of water and it does not dissolve in water, it will float on the water surface. The latex floating on the water surface will be discharged to the outside through the debris outlet, achieving a filtration effect. After use, add a small amount of water to the water storage tank through the water inlet to replenish the loss during cleaning. The water intake positions of the first and second water inlets are both relatively deep, so no latex residue will be extracted. During normal preparation, the electric telescopic rod can drive the bearing sleeve to move. The bearing sleeve drives the connecting shaft to move up and down. The connecting shaft drives the gear plate to be positioned between the first and second gears, and the gear plate does not contact the first and second gears. At this time, the connecting shaft can directly drive the connecting seat to rotate. The connecting seat drives the stirring frame to stir normally without starting the low-pressure water pump or the high-pressure water pump. Attached Figure Description

[0029] Specifically, when preparing hydroxybutyric acid styrene latex, the required materials are put into the reaction vessel 4 through the feed port 6. At this time, the stirring component 7 is started to drive the stirring rack 5 to stir the inside of the reaction vessel 4. At the same time, hot water is connected to the inside of the heating component 3. The heat in the hot water can heat the reaction vessel 4, and the raw materials inside the reaction vessel 4 can be heated. Heating can assist in the preparation of raw materials. After the preparation is completed, the latex can be discharged through the three-way valve 9. At this time, the outlet opposite to the return water pipe 28 of the three-way valve 9 is opened, and the latex will be discharged to the outside through one side of the three-way valve 9.

[0030] Example 1:

[0031] Please see Figure 3 , Figure 4 , Figure 5 and Figure 7 The cleaning structure 2 includes a water storage tank 23 fixed inside the bottom of the support frame 1, a water pumping assembly 21 fixed to one side of the top of the reaction tank 4, a connecting assembly 22 fixed inside the reaction tank 4, a return water pipe 28 fixed to one side of the three-way valve 9, a water distribution chamber 26 set inside the stirring frame 5, a number of equally spaced nozzles 27 arranged on one side of the water distribution chamber 26, and a connecting pipe 25 fixed on one side of the stirring frame 5, which is connected to the water distribution chamber 26.

[0032] The pumping assembly 21 includes a pumping tank 217 and a low-pressure pumping pump 211 installed inside the pumping tank 217. A first inlet pipe 212 is fixed to one side of the low-pressure pumping pump 211, and a first outlet pipe 213 is fixed to the bottom of the low-pressure pumping pump 211. A high-pressure pumping pump 216 is installed inside the pumping tank 217. A second outlet pipe 215 is fixed to one side of the bottom of the high-pressure pumping pump 216, and a second inlet pipe 214 is fixed to the other side of the bottom of the high-pressure pumping pump 216.

[0033] The connecting assembly 22 includes an upper connecting box 225 fixed to the top of the inside of the reaction vessel 4, and a first water inlet 221 is provided on one side of the inside of the upper connecting box 225. A lower connecting box 224 is provided at the bottom of the upper connecting box 225, and a connecting ring 222 is fixed at the top of the lower connecting box 224. The lower connecting box 224 is connected to the upper connecting box 225 through the connecting ring 222. Water outlets 223 are provided on both sides of the bottom of the lower connecting box 224. The lower connecting box 224 is fixedly connected to the stirring rack 5.

[0034] The return water pipe 28 is connected to the water storage tank 23 through the second water inlet 234, the first water inlet pipe 212 is connected to the water storage tank 23 through the water outlet 233, the bottom end of the second water inlet pipe 214 is connected to the water storage tank 23, and the bottom end of the first water outlet pipe 213 is connected to the reaction tank 4.

[0035] Specifically, after the preparation inside the reactor is completed, it needs to be cleaned. At this time, clean water is added to the inside of the water storage tank 23 through the water inlet 231, and the water level does not exceed the height of the debris outlet 232. At this time, the toothed disc 85 is engaged with the first toothed rod 84. Then, the stirring assembly 7 is started to rotate. The stirring assembly 7 drives the connecting sleeve 82 to rotate, the connecting sleeve 82 drives the connecting shaft 83 to rotate, the connecting shaft 83 drives the toothed disc 85 to rotate, and the toothed disc 85 drives the first toothed rod 84 to rotate. At this time, the first toothed rod 84 drives the low-pressure water pump 211. When the system is running, the low-pressure water pump 211 draws water from the water storage tank 23 through the first inlet pipe 212. Then, the low-pressure water pump 211 inputs water into the reaction tank 4 through the first outlet pipe 213, allowing clean water to be filled into the reaction tank 4. Next, the electric telescopic rod 87 is activated to pull the bearing sleeve 89 downward. At this time, the bearing sleeve 89 drives the bottom end of the connecting shaft 83 to insert into the connecting seat 88. Simultaneously, the gear disc 85 moves downward with the connecting shaft 83. The upper part of the gear disc 85 disengages from the first gear 84, and then the lower part of the gear disc 85 engages with the second gear 86. At this time, the stirring assembly 7 rotates, driving the connecting shaft 83 to rotate. The connecting shaft 83 drives the connecting seat 88 to rotate, and the connecting seat 88 drives the stirring frame 5 to stir and clean inside the reaction tank 4. Simultaneously, the connecting shaft 83 drives the gear disc 85 to rotate, which in turn drives the second gear 86 to rotate. The second gear 86 drives the high-pressure water pump 216 to operate. The high-pressure water pump 216 draws water from the water storage tank 23 through the second inlet pipe 214 and inputs it into the upper connecting box 225 through the second outlet pipe 215. The water flow inside the upper connecting box 225 can be connected through the connecting... The gap in the middle of the retaining ring 222 enters the interior of the lower connecting box 224. The lower connecting box 224 can input water into the interior of the connecting pipe 25 through the water outlet 223. The lower connecting box 224 and the upper connecting box 225 are connected by the retaining ring 222, so that the lower connecting box 224 can supply water during rotation. The water flows through the connecting pipe 25 into the water distribution chamber 26. The water distribution chamber 26 distributes the water flow evenly to the nozzle 27. The nozzle 27 sprays high-pressure water and, along with the rotation of the stirring frame 5, cleans the inner wall of the reaction tank 4. At this time, the interior of the reaction tank 4 can be cleaned.

[0036] Example 2:

[0037] Please see Figure 3 , Figure 4 , Figure 6 and Figure 8 The water storage tank 23 includes a water inlet 233 inside it, a second water inlet 234 on one side of the water inlet 233, a water filling port 231 fixed at the top of the water storage tank 23, and a debris outlet 232 fixed on one side of the water storage tank 23.

[0038] The connection switching structure 8 includes a housing 81 fixed to the top of the reaction vessel 4, and a connecting sleeve 82 is movably connected to the top of the housing 81. The top of the connecting sleeve 82 is fixedly connected to the output shaft of the stirring assembly 7. A connecting seat 88 is movably connected to the bottom of the housing 81, and the bottom of the connecting seat 88 is fixedly connected to the top of the stirring frame 5.

[0039] An electric telescopic rod 87 is installed at the bottom inside the outer casing 81, and a bearing sleeve 89 is fixed at the top of the electric telescopic rod 87. A connecting shaft 83 is rotatably connected inside the bearing sleeve 89, and the top of the connecting shaft 83 extends into the interior of the connecting sleeve 82.

[0040] A geared disc 85 is fixed to the outside of the connecting shaft 83. A first gear 84 is movably connected to one side of the inside of the housing 81, and a second gear 86 is provided below the first gear 84. One side of the first gear 84 is fixedly connected to the input shaft of the first water inlet pipe 212, and the second gear 86 is fixedly connected to the input shaft of the high-pressure water pump 216.

[0041] The gear plate 85 and the first gear 84 form a meshing connection. The bearing sleeve 89 forms a lifting structure inside the outer shell 81 through the electric telescopic rod 87. The outer diameter of the connecting shaft 83 is slightly smaller than the inner diameter of the connecting seat 88. The bottom end of the connecting shaft 83 can be inserted into the interior of the connecting seat 88.

[0042] Specifically, after the interior of reaction tank 4 is cleaned, the three-way valve 9 is activated to connect the output port of reaction tank 4 with the return water pipe 28. Then, water containing latex flows into the water storage tank 23. Because the density of latex is lower than water and it does not dissolve in water, it floats on the surface. The floating latex is discharged to the outside through the debris outlet 232, achieving a filtration effect. After use, a small amount of water is added to the water storage tank 23 through the water inlet 231 to replenish the losses during cleaning. Water is drawn from the first inlet pipe 212 and the second inlet pipe 214. The locations are all relatively deep, so no latex residue will be extracted. During normal preparation, the electric telescopic rod 87 can drive the bearing sleeve 89 to move. The bearing sleeve 89 drives the connecting shaft 83 to move up and down. The connecting shaft 83 drives the gear plate 85 to be positioned between the first gear 84 and the second gear 86. The gear plate 85 does not contact the first gear 84 and the second gear 86. At this time, the connecting shaft 83 can directly drive the connecting seat 88 to rotate. The connecting seat 88 drives the stirring frame 5 to stir normally without starting the low-pressure water pump 211 and the high-pressure water pump 216.
