Description

Technical Field

[0001] This application relates to the field of condensation technology, and in particular to a condensation system for an ink semi-finished product dissolving device. Background Technology

[0002] Currently, ink dissolution is a key process in mixing raw materials such as resin, pigment, and solvent to form a homogeneous solution.

[0003] Existing dissolving devices require continuous heating during operation, which generates a large amount of water vapor. If the water vapor accumulates in the dissolving device, it can lead to explosions. Therefore, the water vapor must be released from the device in real time.

[0004] The existing technical solutions mentioned above have the following drawbacks: direct discharge will cause heat loss in the melting device, wasting resources. Utility Model Content

[0005] This application provides a condensation system for an ink semi-finished product dissolving device to recover heat from water vapor.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: A condensation system for an ink semi-finished product dissolving device includes a connecting pipe connected to the dissolving device, a condensing pipe disposed obliquely above the connecting pipe, a flow guide shell connected to both the connecting pipe and the condensing pipe, and a condensing cylinder disposed at the end of the condensing pipe away from the dissolving device. The axes of the connecting pipe and the condensing pipe are parallel to each other, and the condensing pipe is away from the dissolving device. The condensing cylinder is closed at both ends and sleeved on the end of the condensing pipe. The condensing cylinder and the condensing pipe are coaxially arranged. A water inlet pipe and a water outlet pipe are respectively provided on both ends of the condensing cylinder, and the water inlet pipe and the water outlet pipe are connected to the inside and outside of the condensing cylinder.

[0007] By adopting the above technical solution, and by setting up a connecting pipe, a condenser, a guide shell, and a condenser cylinder, with an inlet pipe and an outlet pipe connecting the inside and outside of the condenser cylinder at both ends, the water vapor generated by the dissolving device can enter the guide shell through the connecting pipe, and then be guided into the condenser through the guide shell. At the same time, condensate is introduced into the condenser cylinder through the inlet pipe, and the condensate that has completed heat exchange is discharged through the outlet pipe. This allows the condensate in the condenser cylinder to fully exchange heat with the water vapor in the condenser cylinder, promoting the liquefaction of the water vapor and realizing the recovery of heat from the water vapor. At the same time, the water vapor is discharged from the dissolving device, reducing the accumulation of water vapor in the dissolving device.

[0008] Optionally, the flow guide shell consists of two opposing baffles, a sealing plate disposed between the baffles, and a top plate. The top plate and the sealing plate seal the two baffles. The upper end of the connecting pipe is bent toward the baffle and connected to the end face of the baffle. The lower end face of the condenser is fixed to the end of the side wall of the baffle away from the connecting section. The top plate is inclined. The two ends of the top plate are respectively connected to the ends of the connecting pipe and the condenser. The two ends of the top plate are respectively fixed to the outer peripheral walls of the ends of the connecting pipe and the condenser. The upper side wall of the baffle is inclined and flush with the outer surface of the top plate.

[0009] By adopting the above technical solution, by setting baffles, sealing plates and top plates, with the top plate set at an inclination and its two ends fixed to the outer peripheral walls opposite to the ends of the connecting pipe and the condenser respectively, the guide shell can form a closed guide channel. The inclination top plate can guide the water vapor in the connecting pipe to flow smoothly to the condenser, while reducing the backflow of liquefied water vapor into the dissolving device.

[0010] Optionally, the inner peripheral wall of the condenser tube is provided with a plurality of heat sinks at intervals along its axial direction, and the plurality of heat sinks are evenly distributed at equal angles on the inner peripheral wall of the condenser tube with the axis of the condenser tube as the center.

[0011] By adopting the above technical solution and setting heat sinks, the contact area between water vapor in the condenser tube and the heat sinks can be increased, making it easier for the heat of the water vapor to be transferred to the heat sinks, and then transferred to the condensate in the condenser tube through the heat sinks, thereby improving the heat conversion efficiency and accelerating the liquefaction rate of water vapor.

[0012] Optionally, the side wall of the baffle away from the condenser tube is processed into a protruding arc surface, and the height of both ends of the arc surface is flush with the lower outer peripheral wall of the bent end of the connecting tube. The lower side wall of the baffle and the end face away from the connecting tube are respectively sealed by bent and vertical sealing plates.

[0013] By adopting the above technical solution, by processing the side wall away from the condenser tube into a protruding arc surface and sealing it with a bent sealing plate, the possibility of liquefied water vapor remaining in the guide shell can be reduced when draining.

[0014] Optionally, a baffle is provided inside the flow guide shell. The surface of the baffle is parallel to the surface of the top plate. One end of the baffle is fixed to the pipe wall near the side of the closed plate at the bent end of the connecting pipe. The connection between the baffle and the connecting pipe is treated with a rounded transition.

[0015] By adopting the above technical solution and setting up a baffle, the space inside the guide shell can be divided, reducing the probability of liquefied water vapor flowing back to the connecting pipe and then back to the dissolution device.

[0016] Optionally, the end of the partition near the condenser tube is bent upwards, and the end of the partition away from the connecting pipe is flush with the inner wall of the condenser tube near the top plate.

[0017] By adopting the above technical solution, the upward bending of the baffle near the end of the condenser tube can reduce the possibility of liquefied water vapor entering between the baffle and the top plate when it flows along the inner wall of the condenser tube, thereby further reducing the possibility of liquefied water vapor flowing back to the dissolving device.

[0018] Optionally, the sealing plate on the lower side wall of the baffle is provided with a water outlet that connects the inside and outside. The water outlet is closer to the dissolving device than the bent end of the connecting pipe. The water outlet connects the inside and outside of the guide shell. A drain pipe is provided at the water outlet on the outer surface of the bent sealing plate. The end face of the drain pipe is fixedly connected to the outer wall of the guide shell.

[0019] By adopting the above technical solution, and by setting up an outlet and a drain pipe, the liquefied water condensed inside the guide shell can be collected by gravity and gathered at the outlet near the dissolving device. Then, it enters the drain pipe through the outlet and is discharged from the guide shell by the drain pipe, thus achieving effective collection and discharge of liquefied water and preventing the accumulation of liquefied water inside the guide shell.

[0020] Optionally, the inner and outer walls of the connection between the drain pipe and the guide shell are both treated with rounded transition.

[0021] By adopting the above technical solution, and by using rounded transitions on both the inner and outer walls of the connection between the drain pipe and the guide shell, the liquefied water can flow from the inside of the guide shell into the drain pipe through the outlet without being obstructed by sharp corners on the inner and outer sides of the connection. This makes the flow of liquefied water smoother, reduces the retention of liquefied water on the inner and outer sides of the connection, and ensures that the drain pipe can discharge liquefied water stably and efficiently.

[0022] In summary, this application has the following technical effects: 1. By setting up a connecting pipe, a condenser, a guide shell, and a condenser cylinder, with an inlet pipe and an outlet pipe connecting the inside and outside of the condenser cylinder at both ends, the water vapor generated by the dissolving device can enter the guide shell through the connecting pipe and then be guided into the condenser. At the same time, condensate is introduced into the condenser cylinder through the inlet pipe and discharged through the outlet pipe, allowing the condensate in the condenser cylinder to fully exchange heat with the water vapor in the condenser cylinder, promoting the liquefaction of water vapor and realizing the recovery of heat from water vapor. At the same time, the water vapor is discharged from the dissolving device, reducing the accumulation of water vapor in the dissolving device. 2. By setting baffles, sealing plates and top plates, with the top plate inclined and its two ends fixed to the outer peripheral walls of the connecting pipe end and the condenser pipe end respectively, the guide shell can form a closed guide channel. The inclined top plate can guide the water vapor in the connecting pipe to flow smoothly to the condenser pipe, while reducing the backflow of liquefied water vapor into the dissolving device. 3. By installing heat sinks, the contact area between water vapor in the condenser tube and the heat sinks can be increased, making it easier for the heat of the water vapor to be transferred to the heat sinks, and then transferred to the condensate in the condenser tube through the heat sinks, thereby improving the heat conversion efficiency and accelerating the liquefaction rate of water vapor.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a condensation system for an ink semi-finished product dissolving device, referring to... Figure 1 The condensation system includes a condensation structure 1 connected to the dissolving device, a condensation cylinder 2 located at the end of the condensation structure 1, and a drain pipe 3 connected to the condensation structure 1. Water vapor is guided to the condensation cylinder 2 through the condensation structure 1, and the water vapor is liquefied and flows downward through heat exchange, and is discharged through the drain pipe 3, thereby realizing the heat recovery of water vapor.

[0027] Combination Figure 1 and Figure 2 The condensation structure 1 includes a vertical connecting pipe 11 with its lower end connected to the dissolving device, a flow guide shell 12 connected to the connecting pipe 11, and a vertical condenser pipe 13 connected to the flow guide shell 12. The connecting pipe 11 and the condenser pipe 13 are round pipes of the same specifications. The condenser pipe 13 and the connecting pipe 11 are spaced apart. The lower end of the condenser pipe 13 is higher than the upper end of the connecting pipe 11. The axis of the condenser pipe 13 is parallel to the axis of the connecting pipe 11. The flow guide shell 12 is located on the side of the connecting pipe 11 close to the condenser pipe 13 and is located at the lower part of the condenser pipe 13. The upper end of the connecting pipe 11 and the lower end of the condenser pipe 13 are both connected to the flow guide shell 12.

[0028] Combination Figure 1 and Figure 2The condenser 2 is a cylindrical container, closed at both ends, and fitted around the outer periphery of the condenser tube 13. The condenser 2 and condenser tube 13 are coaxially arranged, with the upper end of the condenser tube 13 being higher than the upper end of the condenser 2. A water inlet pipe 21 is located on the lower end of the condenser 2, and a water outlet pipe 22 is located on the upper end. Both the inlet and outlet pipes connect the inside and outside of the condenser 2. Through the inlet and outlet pipes, condensate flows within the condenser 2, exchanging heat with the water vapor in the condenser tube 13, carrying away heat and liquefying the water vapor. Multiple heat dissipation fins 14 are spaced along the axial direction on the inner periphery of the condenser tube 13. These fins are strip-shaped and evenly spaced at equal angles around the axis of the condenser tube 13. The heat dissipation fins 14 increase the contact area with the water vapor, improving heat conversion efficiency.

[0029] Combination Figure 1 and Figure 2 The flow guide shell 12 consists of two opposing baffles 121, a sealing plate 122 disposed between the baffles 121, and a top plate 123. The baffles 121 are strip plates, and the length direction of the baffles 121 is perpendicular to the axis of the condenser tube 13. The plate surfaces of the two baffles 121 that are opposite to each other are flush with the opposite sides of the outer peripheral wall of the connecting pipe 11. The upper end of the connecting pipe 11 is bent toward the baffles 121 and connected to the lower part of the end face of the baffles 121. The lower end face of the condenser tube 13 is fixedly connected to the upper side wall of the baffle 121 away from the connecting section. The end face of the baffle 121 away from the connecting tube 11 is flush with the outer peripheral wall of the condenser tube 13 away from the connecting tube 11. The side wall of the baffle 121 away from the condenser tube 13 is processed into a protruding arc surface. The height of both ends of the arc surface is flush with the lower outer peripheral wall of the bent end of the connecting tube 11. The lower side wall of the baffle 121 and the end face away from the connecting tube 11 are respectively closed by a bent and a vertical sealing plate 122. The plate surface of the sealing plate 122 is perpendicular to the plate surface of the baffle 121. The outer plate surface of the sealing plate 122 is flush with the end face of the baffle 121 away from the connecting tube 11 and the side wall of the baffle 121 away from the condenser tube 13.

[0030] Referring to the figure, the top plate 123 is inclined, and its two end faces are fixed to the outer peripheral walls of the upper end of the connecting pipe 11 and the lower end of the condenser pipe 13, respectively. The upper side wall of the baffle 121 is inclined and flush with the outer surface of the top plate 123. The top plate 123 and the sealing plate 122 seal the two baffles 121 to form a flow guide shell 12. The flow guide shell 12 is connected to the lower end of the condenser pipe 13 and the upper bent end of the connecting pipe 11. The inner wall of the sealing plate 122 where it connects to the connecting pipe 11 is rounded.

[0031] Combination Figure 1 and Figure 2The flow guide shell 12 is equipped with a baffle 124 inside. The surface of the baffle 124 is parallel to the surface of the top plate 123. One end of the baffle 124 is fixed to the lower side wall of the bent end of the connecting pipe 11. The connection between the baffle 124 and the connecting pipe 11 is treated with an arc transition. The two side walls of the baffle 124 are fixed to the opposite surfaces of the two baffles 121. The end of the baffle 124 near the condenser 13 is bent upward, and the surface of the baffle 124 away from the connecting pipe 11 is flush with the inner wall of the condenser 13 near the top plate 123. The baffle 124 reduces the possibility of liquefied water vapor flowing back to the dissolving device.

[0032] Combination Figure 1 and Figure 2 The sealing plate 122 on the lower side wall of the baffle 121 has an outlet 125 that connects the inside and outside. The outlet 125 is located at the lowest point of the curved sealing plate 122. The outlet 125 is a round hole that connects the inside and outside of the guide shell 12. A drain pipe 3 is provided at the outlet 125 on the outer wall of the guide shell 12. The end face of the drain pipe 3 is fixed to the outer wall of the guide shell 12. The drain pipe 3 is connected to the inside of the guide shell 12 through the outlet 125. The inner and outer walls of the connection between the drain pipe 3 and the guide shell 12 are both treated with arc transition.
