Description

Technical Field

[0001] The utility model relates to the technical field of vacuum salt making, in particular to a device for recycling condensed water used in vacuum salt making. Background Technique

[0002] Vacuum evaporation salt making is also known as "vacuum salt making". It is a modern salt making process. It uses the principle that brine evaporates under a negative pressure state lower than the external atmospheric pressure in the evaporation system to make salt. It has two main processes: evaporation crystallization and dehydration drying.

[0003] The patent document with the publication number CN208465205U, a low-temperature heat-free vacuum salt making device, includes a base. The top of the base is fixedly connected with two support rods. A rotation through hole is opened on the side surface of the support rod, and a rotating rod is rotationally connected to the rotation through hole. In the utility model, by setting a ring, first lift the ring upward. The ring drives the connecting rod and the steel cable to move upward through the inserting rod. The sleeve ring slides along the surface of the evaporation tank. After the inserting rod is completely withdrawn from the second slot, push the ring, so that the inserting rod pushes the evaporation tank and the rotating rod to rotate 90 degrees around the rotation through hole through the connecting rod. Push the inserting rod and insert the inserting rod into the limiting slot to limit the rotation of the inserting rod. At this time, the ball is in contact with the ground, and the steel cable pulls the extrusion block to the top of the extrusion groove. The triangular prism is extruded by the extrusion block and extends out of the bottom of the base, so that the roller is in contact with the ground. At this time, push the inserting rod through the ring, and the inserting rod pushes the base to move through the support rod, achieving the effect of facilitating the movement of the evaporation tank.

[0004] However, through research, it is found that there are certain drawbacks in the above-mentioned vacuum salt making during use:

[0005] In the existing vacuum salt making process, a large amount of water vapor will be evaporated. After the water vapor condenses, it will form condensed water. In the vacuum salt making process, the water vapor will be directly discharged. However, the water vapor contains a lot of heat and the condensed water formed after cooling are all recyclable resources. If directly discharged, it will cause a certain waste of resources. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, the embodiment of the present application provides a device for recycling condensed water used in vacuum salt making. The evaporation water vapor can be collected and condensed through a recovery tank, and the collected condensed water can be stored. Moreover, heat conduction plates are arranged at the upper and lower ends of the recovery tank. The surface of the heat conduction plate is arc-shaped, which increases the contact area of the water vapor, increases the condensation efficiency, and a spiral heat conduction tube is arranged inside the heat conduction plate, which can recover and utilize the heat in the water vapor, so as to achieve the technical effect of double recovery of condensed water and heat.

[0007] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0011] Preferably, the heat conduction component includes heat conduction plates fixedly installed on the inner sides of the top plate and the chassis. The outer surface of the heat conduction plate is arc-shaped, which increases the contact area between the heat conduction plate and water vapor, thereby increasing the cooling efficiency of water vapor. A spiral heat conduction pipe is fixedly installed on the inner wall of the heat conduction plate to conduct heat through the spiral heat conduction pipe.

[0012] Preferably, a water outlet pipe is fixedly installed on the outer surface of the recovery tank. A piston is embedded in one end of the water outlet pipe. A communication pipe is arranged on one side of the recovery tank, and both ends of the communication pipe are fixedly connected to the top plate and the chassis respectively, to conduct the heat inside the top plate and the chassis through the communication pipe, which can be used for salt production heating.

[0013] Preferably, an inner pipe is arranged inside the connector, and the inner pipe is slidably connected to the connector. Through holes are formed around the outer surface of one end of the inner pipe. Water vapor is introduced from one end of the inner pipe and exported to the recovery tank through the through holes.

[0014] Preferably, a retaining ring is fixedly installed at one end inside the connector, and the retaining ring is sleeved on the outer surface of one end of the inner pipe to close the through holes at one end of the inner pipe.

[0015] Preferably, a baffle is fixedly installed at one end of the inner pipe, a top ring is integrally installed at the other end of the inner pipe, and a return spring is sleeved on the outer surface of the inner pipe on one side of the retaining ring. Both ends of the return spring are in contact connection with the outer surfaces of the top ring and the retaining ring respectively. During the process of pushing the inner pipe, the return spring will be compressed. After the water vapor is exported, the inner pipe is reset through the return spring.

[0016] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0017] First, the condensate water recovery and utilization device for vacuum salt production of the present utility model can collect and condense the evaporated water vapor through the recovery tank, store the collected condensate water, and heat conduction plates are arranged at the upper and lower ends of the recovery tank. The surface of the heat conduction plate is arc-shaped, which increases the contact area of water vapor, increases the condensation efficiency, and a spiral heat conduction pipe is arranged inside the heat conduction plate to recover and utilize the heat in the water vapor, so as to achieve double recovery of condensate water and heat.

[0018] Second, in a condensate water recycling device for vacuum salt production of the present utility model, an inner tube is arranged inside the joint. When water vapor is generated, the air pressure increases, pushing the inner tube and thus opening the through hole. After the water vapor is transported, the air pressure returns, and the inner tube will be reset by the return spring to close the through hole, avoiding the backflow of water vapor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Embodiment 1:

[0026] A condensate water recycling device for vacuum salt production, as Figures 4 - 5 shown, includes an evaporation tank 1. An upper cover 11 is installed at the top end of the evaporation tank 1. A delivery pipe 12 is fixedly installed at the center of the top end of the upper cover 11. One end of the delivery pipe 12 is fixedly installed with a joint 13. An anti-backflow component is arranged inside the joint 13 to avoid the backflow of water vapor through the anti-backflow component;

[0027] Among them, as Figure 4 shown, an inner tube 14 is arranged inside the joint 13, and the inner tube 14 is slidably connected to the joint 13. A through hole 19 is formed around the outer surface of one end of the inner tube 14. The water vapor generated during salt production is exported and transported through the delivery pipe 12. Because the air pressure in the evaporation tank 1 increases due to the increase in water vapor, the inner tube 14 inside the joint 13 is pushed by the air pressure and one end is pushed out of the joint 13, thereby opening the through hole 19 at one end.

[0028] Among them, as Figure 4As shown in the figure, a retaining ring 17 is fixedly installed at the inner end of the joint 13, and the retaining ring 17 is sleeved on the outer surface of one end of the inner tube 14. When the increase of water vapor stops, the air pressure in the evaporation tank 1 recovers. At this time, the return spring 16 will drive the inner tube 14 to pull back to its original position, and the through hole 19 will be closed by the retaining ring 17 to avoid the backflow of water vapor.

[0029] Among them, as Figure 5 shown, a baffle 18 is fixedly installed at one end of the inner tube 14, a top ring 15 is integrally installed at the other end of the inner tube 14, a return spring 16 is sleeved on the outer surface of the inner tube 14 on one side of the retaining ring 17, and the two ends of the return spring 16 are in contact connection with the outer surfaces of the top ring 15 and the retaining ring 17 respectively. During the process of the inner tube 14 being pushed, the top ring 15 will squeeze the return spring 16.

[0030] In a condensate water recovery and utilization device for vacuum salt production of the present utility model, the water vapor generated during salt production is exported and conveyed through the conveying pipe 12. Because the increase of water vapor increases the air pressure in the evaporation tank 1, the inner tube 14 in the joint 13 is pushed by the air pressure and one end is pushed out of the joint 13, thus opening the through hole 19 at one end. At the same time, the top ring 15 will squeeze the return spring 16, and the water vapor will enter the recovery tank 2 through the through hole 19 for recovery treatment. When the increase of water vapor stops, the air pressure in the evaporation tank 1 recovers. At this time, the return spring 16 will drive the inner tube 14 to pull back to its original position, and the through hole 19 will be closed by the retaining ring 17 to avoid the backflow of water vapor.

[0031] Embodiment 2:

[0032] On the basis of Embodiment 1, as Figures 1 - 3 shown, this embodiment includes a recovery tank 2. The recovery tank 2 is arranged on one side of the evaporation tank 1. The evaporation tank 1 is connected to the recovery tank 2 through a conveying pipe 12. The upper and lower ends of the recovery tank 2 are respectively fixedly installed with a chassis 22 and a top plate 23. A heat conduction component is arranged inside the chassis 22 and the top plate 23, and the heat of the water vapor is absorbed through the heat conduction component to condense the water vapor into condensed water.

[0033] Among them, as Figure 3 shown, the heat conduction component includes heat conduction plates 24 fixedly installed on the inner sides of the top plate 23 and the chassis 22. The outer surface of the heat conduction plate 24 is arc-shaped to increase the contact area of the water vapor and improve the condensation efficiency. A spiral heat conduction pipe 25 is fixedly installed on the inner wall of the heat conduction plate 24, which can recover and utilize the heat in the water vapor.

[0034] Among them, as Figure 2As shown, a water outlet pipe 21 is fixedly installed on the outer surface of the recovery tank 2. A connecting pipe 26 is arranged on one side of the recovery tank 2, and both ends of the connecting pipe 26 are fixedly connected to the top plate 23 and the bottom plate 22 respectively. The heat in the bottom plate 22 and the top plate 23 can be transported and recovered through the connecting pipe 26. After the heat in the condensed water is recovered, the condensed water in the recovery tank 2 can be discharged and recovered through the water outlet pipe 21.

[0035] For a condensed water recovery and utilization device for vacuum salt production of the present utility model, after the generated water vapor enters the recovery tank 2, the heat in the water vapor is absorbed and transferred through the heat conduction plates 24 at the upper and lower ends of the recovery tank 2. The surface of the heat conduction plate 24 is arc-shaped, which increases the contact area of the water vapor and improves the condensation efficiency. And a spiral heat conduction pipe 25 is arranged inside the heat conduction plate 24, which can recover and utilize the heat in the water vapor. The heat in the bottom plate 22 and the top plate 23 can be transported and recovered through the connecting pipe 26. After the heat in the condensed water is recovered, the condensed water in the recovery tank 2 can be discharged and recovered through the water outlet pipe 21, and so on in a cycle.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
