Description

Technical Field

[0001] This utility model relates to the field of styrene-butadiene latex production technology, specifically to a styrene-butadiene latex bubble eliminator. Background Technology

[0002] Styrene-butadiene latex is a stable emulsion formed by the low-temperature polymerization of butadiene and styrene. During the processing and production of styrene-butadiene latex, air bubbles are trapped in the liquid and cannot be expelled. The presence of air bubbles in the styrene-butadiene latex will affect its quality. Therefore, it is necessary to eliminate the air bubbles in the styrene-butadiene latex.

[0003] For example, the authorization announcement number "CN221107088U" describes a styrene-butadiene latex bubble eliminator. This device uses an air extraction pipe to draw air from the inside of the degassing cylinder, and a scraping mechanism to scrape the inner wall of the cylinder, preventing styrene-butadiene latex from adhering and causing waste. A support mechanism supports the equipment while reducing vibration transmission and noise. However, existing styrene-butadiene latex bubble eliminators suffer from limitations. Since the bubbles inside the styrene-butadiene latex are formed by external air introduced during mixing or feeding, while agitation and puncture can eliminate these bubbles, this method is only effective for larger, easily punctured bubbles. It leaves gaps in eliminating numerous, small bubbles, thus affecting the overall bubble elimination effect of the styrene-butadiene latex bubble eliminator. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor bubble elimination effect of styrene-butadiene latex bubble eliminators, and to propose a styrene-butadiene latex bubble eliminator.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A styrene-butadiene latex bubble eliminator is designed, comprising an eliminator tank, a base, and support columns. Multiple support columns are fixedly installed on the top of the base. The lower end of the eliminator tank is fixedly connected to the top of the multiple support columns. The inner side of the eliminator tank is provided with a heating structure to accelerate the elimination of small bubbles. The upper part of the eliminator tank is provided with a rotating and agitating structure to eliminate bubbles. The bottom end of the eliminator tank is provided with a styrene-butadiene latex discharge structure. The upper two sides of the eliminator tank are provided with feeding and venting structures.

[0007] Preferably, the heating-accelerated small bubble elimination structure includes an inner cavity and a timer. The inner cavity is fixedly installed inside the elimination tank, and the two timers are fixedly installed on the outer wall of the elimination tank. Two heating plates are fixedly installed inside the inner cavity, and multiple heat-conducting sheets are fixedly connected to the inner walls of the two heating plates. The other ends of the multiple heat-conducting sheets are fixedly connected to the inside of the inner cavity, and the two timers are electrically connected to the heating plates through wires.

[0008] Preferably, the rotating agitation bubble-eliminating structure includes a motor and connecting rods. The motor is fixedly installed at the top of the bubble-eliminating tank. A transmission rod is fixedly connected to the lower end of the motor's output shaft. Multiple connecting rods are fixedly installed on the inner wall of the inner cavity. Limiting rings are fixedly installed at the ends of the multiple connecting rods. The inner sides of the multiple limiting rings are rotatably connected to the transmission rods through bearings. Multiple stirring rollers are fixedly connected to the outer wall of the transmission rods. Multiple puncture needles are fixedly connected to the outer sides of the multiple stirring rollers.

[0009] Preferably, the styrene-butadiene latex discharge structure includes a discharge pipe and a receiving platform. The discharge pipe is fixedly installed at the bottom of the elimination tank, and the inner side of the discharge pipe is connected to the bottom of the inner cavity. A discharge valve is fixedly installed on the outside of the discharge pipe, and the receiving platform is fixedly installed above the base.

[0010] Preferably, the lower end of the discharge pipe is positioned opposite to the upper part of the receiving platform, and the bottom ends of the plurality of support columns are fixedly connected to the side of the receiving platform.

[0011] Preferably, the feeding and venting structure includes feeding boxes and venting pipes. Two feeding boxes are fixedly installed on both sides of the outer wall of the elimination tank. The top of the two feeding boxes is fixedly provided with a pouring hole. The outer side of the two pouring holes is threaded with a sealing cap. The inner side of the two feeding boxes is fixedly connected with a conveying pipe. The other end of the two conveying pipes is fixedly connected to the inner side of the inner cavity. The two venting pipes are fixedly connected to the top of the elimination tank. A one-way valve is fixedly installed above the two venting pipes. An exhaust pump is fixedly installed on the outer side of the two venting pipes.

[0012] The present invention proposes a styrene-butadiene latex bubble eliminator, the beneficial effects of which are as follows: After pouring styrene-butadiene latex raw materials and defoaming agent into the inner cavity to eliminate bubbles, the heating plate is activated by a timer after connecting to a power source. The heating plate generates a certain amount of heat, which is transferred to the inner cavity by a heat-conducting plate made of copper. The styrene-butadiene latex mixed with the defoaming agent is heated together. During heating, small clumps of air or gas in the liquid form bubbles due to the decrease in solubility. These bubbles can then rise and be expelled, thereby achieving the effect of removing bubbles. The heating method eliminates small bubbles in the styrene-butadiene latex, while the puncturing needle can eliminate large bubbles in the styrene-butadiene latex, thus improving the bubble elimination effect of the styrene-butadiene latex bubble eliminator.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a styrene-butadiene latex bubble eliminator includes an eliminator tank 1, a base 2, and support columns 3. Multiple support columns 3 are fixedly installed above the base 2. The lower end of the eliminator tank 1 is fixedly connected to the top of the multiple support columns 3. The multiple support columns 3 are made of stainless steel. The support columns 3 support and fix the top of the eliminator tank 1 above the base 2. The inner side of the eliminator tank 1 is provided with a heating structure 4 to accelerate the elimination of small bubbles. The upper part of the eliminator tank 1 is provided with a rotating and stirring structure 5 to eliminate bubbles. The bottom end of the eliminator tank 1 is provided with a styrene-butadiene latex discharge structure 6. The upper two sides of the eliminator tank 1 are provided with feeding and venting structures 7.

[0023] The heating-accelerated small bubble elimination structure 4 includes an inner cavity 41 and a timer 42. The inner cavity 41 is fixedly installed inside the elimination tank 1 and is made of stainless steel. Stainless steel has good non-stick and heat-resistant properties. The two timers 42 are fixedly installed on the outer wall of the elimination tank 1. The timer 42 is a relatively mature technology at present. The operator can control the automatic adjustment of the start time of the heating plate 43 through the timer 42.

[0024] When the styrene-butadiene latex raw material and defoamer for eliminating bubbles are poured into the inner cavity 41, the heating plate 43 is started by connecting the power supply at a timer. The heating plate 43 will generate a certain amount of heat. Two heating plates 43 are fixedly installed inside the inner cavity 41. Multiple heat-conducting plates 44 are fixedly connected to the inner walls of the two heating plates 43. The heat-conducting plates 44 are made of copper. After the heating plate 43 generates heat, the heat-conducting plates 44 made of copper will transfer the heat to the inside of the inner cavity 41, heating the styrene-butadiene latex mixed with the defoamer together.

[0025] The principle of the heating method is that the increase in liquid temperature will cause the solubility of gas in the liquid to decrease, thereby forming bubbles and escaping. During heating, small clumps of air or gas in the liquid form bubbles due to the decrease in solubility. These bubbles can then rise and escape, thereby achieving the effect of removing bubbles. The other ends of multiple heat-conducting plates 44 are fixedly connected to the inside of the inner cavity 41, and two timers 42 are electrically connected to the heating plate 43 through wires.

[0026] The inner cavity 41 is made of stainless steel, which has good non-stick and heat-resistant properties. When the styrene-butadiene latex raw material and defoamer for eliminating bubbles are poured into the inner cavity 41, the heating plate 43 is started by connecting the power supply at a timer. The heating plate 43 will generate a certain amount of heat. After the heating plate 43 generates heat, the heat-conducting plate 44 made of copper will transfer the heat to the inside of the inner cavity 41, heating the styrene-butadiene latex mixed with the defoamer together. The principle of the heating method is that the increase in the temperature of the liquid will cause the solubility of the gas in the liquid to decrease, thereby forming bubbles and escaping.

[0027] When heated, small clumps of air or gas in the liquid form bubbles due to the decrease in solubility. These bubbles can then rise and be expelled, thereby achieving the effect of removing bubbles. Heating is used to eliminate small bubbles in styrene-butadiene latex, while the puncture needle 55 can eliminate large bubbles in styrene-butadiene latex, thus improving the bubble elimination effect of the styrene-butadiene latex bubble eliminator.

[0028] The rotating agitation defoaming structure 5 includes a motor 51 and connecting rods 53. The motor 51 is fixedly installed at the top of the defoaming tank 1. The motor 51 is a servo motor. When selecting a servo motor, you can choose a motor model that meets the usage requirements. The lower end of the output shaft of the motor 51 is fixedly connected to a transmission rod 52. Multiple connecting rods 53 are fixedly installed on the inner wall of the inner cavity 41. When the styrene-butadiene latex raw material and defoamer are poured into the inner cavity 41, the power is connected and the motor 51 is started. The motor 51 can drive the transmission rod 52 below to rotate.

[0029] Multiple connecting rods 53 are fixedly installed at their ends with limiting collars 54. The limiting collars 54 are supported on the inner wall of the inner cavity 41 by the connecting rods 53. At the same time, the inner side of the limiting collars 54 is supported by bearings to start the rotating transmission rod 52. The inner side of the multiple limiting collars 54 is rotatably connected to the transmission rod 52 through bearings. The transmission rod 52 drives multiple outer stirring rollers 56 to mix and stir the styrene-butadiene latex raw material and defoamer. The sharp tip of the puncturing needle 55 can puncture large air bubbles to allow the air in the bubbles to escape. Multiple stirring rollers 56 are fixedly connected to the outer wall of the transmission rod 52, and multiple puncturing needles 55 are fixedly connected to the outer side of the multiple stirring rollers 56.

[0030] The styrene-butadiene latex discharge structure 6 includes a discharge pipe 61 and a receiving platform 63. The discharge pipe 61 is fixedly installed at the bottom of the elimination tank 1. The inner side of the discharge pipe 61 is connected to the bottom of the inner cavity 41. When the air bubbles inside the styrene-butadiene latex are eliminated to the standard, the operator can open the lower discharge valve 62. The discharge valve 62 opens the bottom of the discharge pipe 61, and the styrene-butadiene latex stored in the inner cavity 41 will automatically flow downward. The discharge valve 62 is fixedly installed on the outside of the discharge pipe 61. The receiving platform 63 is fixedly installed above the base 2. The receiving platform 63 can hold the styrene-butadiene latex that has been eliminated. The lower end of the discharge pipe 61 is opposite to the upper end of the receiving platform 63. The bottom ends of multiple support columns 3 are fixedly connected to the side of the receiving platform 63.

[0031] Working principle:

[0032] When using a styrene-butadiene latex bubble eliminator, the styrene-butadiene latex raw material containing bubbles, along with a certain amount of defoamer, is poured into the eliminator tank. The defoamer is an existing technology, which is a defoamer refined from mineral oil and polyether ester through a special process. It can quickly eliminate the bubbles contained in the styrene-butadiene latex. Then, by combining heating and stirring to burst the bubbles, the bubbles of all sizes can be quickly eliminated.

[0033] The heating structure of the styrene-butadiene latex bubble eliminator eliminates small bubbles:

[0034] The inner cavity 41 is made of stainless steel, which has good non-stick and heat-resistant properties. When styrene-butadiene latex raw materials and defoaming agents are poured into the inner cavity 41 to eliminate air bubbles, the heating plate 43 is activated by a timer. The heating plate 43 generates heat, which is then transferred to the inner cavity 41 by a copper heat-conducting plate 44. This heats the styrene-butadiene latex mixed with the defoaming agent. The principle of this heating method is that an increase in liquid temperature leads to a decrease in the solubility of gases in the liquid, causing bubbles to form and escape. During heating, small air or gas particles in the liquid form bubbles due to the reduced solubility. These bubbles then rise and escape, thus removing the bubbles. Heating eliminates small bubbles in the styrene-butadiene latex, while a puncturing needle 55 can eliminate large bubbles.

[0035] The rotating puncture and bubble-removing structure of the styrene-butadiene latex bubble eliminator:

[0036] After the styrene-butadiene latex raw material and defoamer are poured into the inner cavity 41, the power supply is connected and the motor 51 is started. The motor 51 can drive the transmission rod 52 below to rotate. The ends of multiple connecting rods 53 are fixedly installed with limiting collars 54. The limiting collars 54 are supported on the inner wall of the inner cavity 41 by the connecting rods 53. At the same time, the inner side uses bearings to start the support of the rotating transmission rod 52. The inner side of the multiple limiting collars 54 is rotatably connected to the transmission rod 52 through bearings. The transmission rod 52 drives multiple stirring rollers 56 on the outside to mix and stir the styrene-butadiene latex raw material and defoamer. The sharp tip of the puncturing needle 55 can puncture large air bubbles and allow the air in the bubbles to escape.

[0037] The discharge structure of the styrene-butadiene latex bubble eliminator:

[0038] Once the air bubbles inside the styrene-butadiene latex have been eliminated to the required standard, the operator can open the lower discharge valve 62. The discharge valve 62 opens the bottom of the discharge pipe 61, and the styrene-butadiene latex stored in the inner cavity 41 will automatically flow downwards. The discharge valve 62 is fixedly installed on the outside of the discharge pipe 61, and the receiving platform 63 is fixedly installed above the base 2. The receiving platform 63 can hold the styrene-butadiene latex that has been de-aired.

[0039] Example 2:

[0040] Please see Figure 1-6In this embodiment, a styrene-butadiene latex bubble eliminator further includes a feeding and venting structure 7 comprising a feeding box 71 and an venting pipe 75. Two feeding boxes 71 are fixedly installed on both sides of the outer wall of the eliminator tank 1. A pouring hole 73 is fixedly opened at the top of each feeding box 71. A sealing cover 72 above the pouring hole 73 is made of plastic material with internal threads. The sealing cover 72 can be rotated and fastened. The sealing cover 72 is threaded onto the outer sides of the two pouring holes 73. When the sealing cover 72 is rotated open, the operator can pour defoamer into one side and pour styrene-butadiene latex raw material containing bubbles into the feeding box 71 on the other side. The inner sides of the two feeding boxes 71... A feed pipe 74 is fixedly connected to the inner cavity 41, which introduces defoamer and styrene-butadiene latex raw material into the inner cavity 41 for storage and waiting to eliminate bubbles. The other ends of the two feed pipes 74 are fixedly connected to the inner side of the inner cavity 41. Two exhaust pipes 75 are fixedly connected to the top of the elimination tank 1. When the gas in the bubbles is punctured by heating and rotation, the gas will rise and accumulate at the top of the inner cavity 41 until the operator activates the exhaust pump 77 and the one-way valve 76. The gas discharged will then enter the outside air along the exhaust pipe 75. The one-way valve 76 is fixedly installed above the two exhaust pipes 75, and the exhaust pump 77 is fixedly installed on the outside of the two exhaust pipes 75.

[0041] Working principle:

[0042] The sealing cap 72 above the pouring hole 73 is made of plastic material with internal threads. The sealing cap 72 can be rotated and fastened. The sealing cap 72 is connected to the outer threads of the two pouring holes 73. When the sealing cap 72 is rotated open, the operator can pour defoamer into one side and pour styrene-butadiene latex raw material with bubbles into the feeding box 71 on the other side. The conveying pipe 74 introduces the defoamer and styrene-butadiene latex raw material into the inner cavity 41 for storage to wait for the bubbles to be eliminated. When heated and rotated to puncture and expel the gas in the bubbles, the gas will rise and accumulate at the top of the inner cavity 41 until the operator activates the exhaust pump 77 and the one-way valve 76. In this way, the gas will be discharged upward into the outside air along the exhaust pipe 75.
