Description

Technical Field

[0001] The present invention relates to the technical field of condensation reflux, and particularly relates to an efficient condensation reflux device. Background Art

[0002] Styrene-acrylic resin is a copolymer formed by polymerizing styrene and acrylate monomers. Other functional monomers are often added to adjust its properties. According to its uses, it has types such as for coatings, inks, and adhesives, and has characteristics such as weather resistance, water resistance, good mechanical properties, good gloss, and good chemical stability. The synthesis methods include emulsion polymerization and solution polymerization methods, and it is widely used in fields such as coatings, inks, adhesives, plastic modification, fabric finishing, and electronic materials.

[0003] The production process of styrene-acrylic resin usually involves styrene, acrylate monomers, and solvents such as toluene and xylene. These substances generally have the characteristic of relatively low boiling points. In a high-temperature reaction environment, they are extremely easy to change from a liquid state to a gaseous state and volatilize. Once volatilized into a gas, the molecular spacing of these substances increases and the volume immediately expands. The internal space of the production equipment is limited. If the expanded gas cannot be effectively discharged in time, it will cause a sharp increase in the internal pressure of the equipment, and in severe cases, it may even lead to equipment failures and affect production safety. If these volatile gases containing styrene, acrylate monomers, and toluene, xylene, etc. are discharged into the external environment, it will cause many pollution problems. Summary of the Invention

Specific embodiments

[0022] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Embodiment 1

[0024] As Figures 1 - 4 shown, this embodiment provides an efficient condensation and reflux device, including a heating reaction kettle 1, a fixing frame 4 is fixedly installed on the lower side of the outer surface of the heating reaction kettle 1, a blanking pipe 2 is installed through the middle of the bottom end of the heating reaction kettle 1, a feeding door 3 is installed in an opening and closing manner on one side of the top end of the heating reaction kettle 1 away from the middle, a condensation component 5 is arranged in the middle of the top end of the heating reaction kettle 1, a heat dissipation component 6 is fixedly arranged on the outer side of the top end of the heating reaction kettle 1 away from the middle, and a circulating component 7 is arranged between the heat dissipation component 6 and the condensation component 5;

[0025] In the implementation process of this embodiment, the condensation component 5 is set to condense the styrene resin material evaporated into gas due to heating in the heating reaction kettle 1, so that the high-pressure gaseous styrene resin material is cooled and converted into liquid state and then flows back into the heating reaction kettle 1 for further processing.

[0026] Specifically, the condensation component 5 includes a connecting pipe 51, the connecting pipe 51 is installed through the middle of the top end of the heating reaction kettle 1, the upper side of the outer surface of the connecting pipe 51 is coaxially fixedly connected with a first heat dissipation spherical shell 52, and the top end of the connecting pipe 51 inside the first heat dissipation spherical shell 52 is coaxially fixedly connected with a second heat dissipation spherical shell 53;

[0027] There is a cold liquid layer 54 between the second heat dissipation spherical shell 53 and the first heat dissipation spherical shell 52, a rotating rod 55 is rotatably installed in the middle of the upper side of the inner cavity side wall of the cold liquid layer 54, and a plurality of arc-shaped fan plates 56 are annularly arranged on the outer surface of the rotating rod 55;

[0028] After the styrene resin is heated and evaporated into a gaseous state, it floats upward due to the effect of heat convection and enters the second heat dissipation spherical shell 53 through the connecting pipe 51. When the gaseous styrene resin with a very high temperature enters the second heat dissipation spherical shell 53 and contacts its inner wall, since the temperature of the inner wall of the second heat dissipation spherical shell 53 is relatively low, the gaseous styrene resin quickly dissipates heat, the distance between molecules decreases, and a physical state change occurs, condensing into a liquid state. It slowly flows down along the inner wall of the second heat dissipation spherical shell 53 and re-converges inside the heating reaction kettle 1;

[0029] There is a cold liquid layer 54 between the first heat dissipation spherical shell 52 and the second heat dissipation spherical shell 53. The cold liquid layer 54 is filled with coolant, which prevents the temperature of the second heat dissipation spherical shell 53 from rising after being heated for a long time and unable to condense the high-temperature gaseous styrene resin. The coolant in the cold liquid layer 54 is circulated and cooled through the circulation component 7 and the heat dissipation component 6, which avoids the phenomenon that the coolant in the cold liquid layer 54 heats up during long-term condensation operation;

[0030] When the coolant in the cold liquid layer 54 circulates, the water flow drives a plurality of arc-shaped fan plates 56 to rotate around the rotating rod 55. Thus, the relatively hot coolant gathered on the outer surface of the second heat dissipation spherical shell 53 can be agitated to prevent the coolant near the outer surface of the second heat dissipation spherical shell 53 in the cold liquid layer 54 from accumulating on the outer surface of the second heat dissipation spherical shell 53 to form heat accumulation.

[0031] Embodiment 2

[0032] Based on Embodiment 1, this solution enables the coolant in the heat dissipation component 6 and the condensation component 5 to circulate through the circulation component 7, preventing the coolant in the condensation component 5 from accumulating heat and reducing the condensation effect of the condensation component 5. Thus, the condensation and reflux effects of the condensation component 5 are efficiently enhanced.

[0033] As Figures 3 - 5 shown, the heat dissipation component 6 includes a liquid chamber 61. The liquid chamber 61 is coaxially and fixedly installed on the outer side of the top of the heating reaction kettle 1 away from the middle. A rotating ring 62 is rotatably installed in the middle of the inner side wall of the liquid chamber 61. On the side of the rotating ring 62 away from the inner side wall of the liquid chamber 61, a plurality of stirring blades 63 are fixedly installed in an annular array;

[0034] A plurality of heat dissipation fins 64 are annularly arrayed on the outer surface of the liquid chamber 61;

[0035] When the coolant in the cold liquid layer 54 is transported into the liquid chamber 61 through the circulation component 7, the temperature of the coolant transported into the liquid chamber 61 is quickly dissipated to the surrounding environment through the outer shell of the liquid chamber 61 and the plurality of heat dissipation fins 64, reducing the temperature of the coolant, thereby ensuring that the coolant always maintains a relatively low working temperature;

[0036] During the process of the circulation component 7 transporting the cold liquid layer 54 and the coolant in the liquid storage chamber 61, the flowing coolant drives the rotation of a plurality of stirring vanes 63 on the outer surface of the rotating ring 62, thus accelerating the flow uniformity of the coolant in the liquid storage chamber 61 and avoiding the formation of two uneven flow layers of hot and cold.

[0037] Furthermore, the circulation component 7 includes a water pump 71 and a second liquid pipe 73. The water pump 71 is fixedly installed on one side near the axis at the top end of the heating reactor 1. One end of the second liquid pipe 73 penetrates and is fixedly connected to the upper side of the outer surface of the heat dissipation spherical shell 52. The other end of the second liquid pipe 73 penetrates and is fixedly connected to the side of the top end of the liquid storage chamber 61 far from the middle in an inclined manner;

[0038] The output end of the water pump 71 is fixedly connected with a first liquid pipe 72. The end of the first liquid pipe 72 far from the water pump 71 penetrates and is fixed to the lower side of the outer surface of the heat dissipation spherical shell 52. The positions of the first liquid pipe 72 and the second liquid pipe 73 are staggered with each other. The input end of the water pump 71 is fixedly connected with a third liquid pipe 74. The end of the third liquid pipe 74 far from the water pump 71 penetrates and extends into the inner cavity of the liquid storage chamber 61;

[0039] When the water pump 71 is started, the output shaft of the water pump 71 is communicated with the liquid storage chamber 61 through the third liquid pipe 74, and the output shaft of the water pump 71 is communicated with the cold liquid layer 54 through the first liquid pipe 72. In addition, the cold liquid layer 54 is communicated with the liquid storage chamber 61 through the second liquid pipe 73. Thus, when the water pump 71 does work, the coolant in the liquid storage chamber 61 is transported into the cold liquid layer 54. After the cold liquid layer 54 is full, the coolant in its inner cavity flows back into the liquid storage chamber 61 through the second liquid pipe 73 for circulating flow.

[0040] It should be particularly noted that the specific installation method, the connection method of the circuit and the control method of the water pump 71 adopted in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
