Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, and in particular to a jet-type high-efficiency heat exchange system. Background Technology

[0002] A jet heat exchanger, also known as a jet heat exchanger, is a type of ejector used for heat exchange. It is used to mix two fluids with different pressures and temperatures and exchange energy during the mixing process. Jet heat exchangers can perform heat exchange between steam and water, water and water, and steam and steam. The jet heat exchanger mainly consists of a shell, a nozzle, and an inlet pipe. The working fluid expands through the nozzle and is ejected from the nozzle at a high speed, entraining the lower-pressure entrained fluid into the inlet chamber. The working fluid transfers some of its kinetic energy to the entrained fluid. During the flow along the ejector, the working fluid and the entrained fluid mix in the mixing chamber of the shell and then enter the diffusion chamber. After diffusion occurs in the diffusion chamber, the velocity of the mixed fluid gradually reaches equilibrium before flowing into the pipe from the outlet.

[0003] In common jet-type heat exchangers, high-temperature water enters through a high-temperature water pipe and low-temperature water enters through a low-temperature water pipe. After heat exchange, the water is discharged directly from the outlet.

[0004] In existing jet-type high-efficiency heat exchange systems, the water is directly discharged through a drain outlet after heat exchange, which inevitably leads to some impurities in the water, thus affecting subsequent use. Therefore, a jet-type high-efficiency heat exchange system is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a jet-type high-efficiency heat exchange system, which aims to improve the problems of impurities in the water after heat exchange and the inability to control the rate at which low-temperature water enters the pipe.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a jet-type high-efficiency heat exchange system, comprising two flanges, one flange having a high-temperature water pipe fixedly connected to one end, and the other flange having a water outlet pipe fixedly connected to one end. A sealing box is fixedly connected inside the water outlet pipe, a filter plate is slidably connected inside the sealing box, a sealing strip is fixedly connected to the outside of the filter plate, a protective shell is fixedly connected inside the sealing box, an outer shell is fixedly connected inside the protective shell, a pin is slidably connected inside the outer shell, a metal spring is sleeved on the outside of the pin, a pad is fixedly connected to the outside of the pin, a pull rod is fixedly connected to the outside of the pad, an L-shaped groove is opened on the outside of the outer shell, an arc-shaped groove is opened on one side of the protective shell, a low-temperature water pipe is fixedly connected inside the high-temperature water pipe, and a control component for controlling the cold water flow rate is provided on the outside of the low-temperature water pipe.

[0007] As a further description of the above technical solution:

[0008] The control component includes a baffle plate, which is rotatably connected inside the low-temperature water pipe. A rotating rod is rotatably connected inside the low-temperature water pipe. A fixing rod is fixedly connected to the outside of the low-temperature water pipe. A protective box is fixedly connected to the outside of the fixing rod. A rotating shaft is rotatably connected inside the protective box. A rope is sleeved on the outside of the rotating shaft. A spring is sleeved on the outside of the rotating shaft.

[0009] As a further description of the above technical solution:

[0010] The outer side of the pull rod is slidably connected inside the L-shaped groove, and the outer side of the pull rod is slidably connected inside the arc-shaped groove.

[0011] As a further description of the above technical solution:

[0012] One end of the metal spring is fixedly connected to one side of the pad, and the other end of the metal spring abuts against the inner wall of the outer shell.

[0013] As a further description of the above technical solution:

[0014] A pull ring is fixedly connected to the end of the pin away from the pad, and the pad is slidably connected inside the housing.

[0015] As a further description of the above technical solution:

[0016] The rotating rod passes through the low-temperature water pipe and is rotatably connected to the other inner wall of the low-temperature water pipe. A disc is fixedly connected to one end of the rotating rod.

[0017] As a further description of the above technical solution:

[0018] One end of the rope is fixedly connected to the outside of the rotating shaft, and the other end of the rope is fixedly connected to the outside of the rotating rod.

[0019] As a further description of the above technical solution:

[0020] One end of the spring is fixedly connected to the outside of the rotating shaft, and the other end of the spring is fixedly connected to the inner wall of the protective box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the filter plate needs to be replaced or cleaned, the pull ring is pulled, which drives the pin. The pad fixed on the outside of the pin slides inside the outer shell. The pull rod is fixed on the outside of the pad. When the pin is pulled out of the filter plate, the pin is rotated so that the pull rod is locked in the L-shaped groove. When the pin is disengaged from the filter plate, the handle is pulled upward to pull the filter plate out of the sealed box. When the filter plate is replaced or cleaned, it is reinserted into the sealed box. The pin is then rotated, and under the action of the metal spring, the pin is reinserted into the filter plate. This makes it convenient for workers to replace or clean the filter plate and saves manpower.

[0023] 2. In this utility model, by rotating the disc, the rotating rod fixed to the disc rotates along with the baffle plate inside the low-temperature water pipe. The rope fixed on the rotating rod then winds around the outside of the rotating rod as the disc rotates, thereby stretching the spring in the protective box and driving the rotating shaft to rotate. The angle of rotation of the baffle plate is known by the number of turns of the rope wound on the rotating rod. When the rotation stops, the spring in the protective box contracts, thereby driving the rotating shaft to rotate in the opposite direction. Therefore, the rope is retracted to the outside of the rotating shaft, which makes it convenient for the staff to control the flow rate of the water in the low-temperature water pipe, thereby controlling the temperature of the water coming out of the outlet pipe.

The housing 21 provides a place for the internal components to operate normally.

[0038] Reference Figure 1 - Figure 3 The rotating rod 4 passes through the low-temperature water pipe 1 and is rotatably connected to the other inner wall of the low-temperature water pipe 1. A disc 5 is fixedly connected to one end of the rotating rod 4. The low-temperature water pipe 1 is used for the entry of low-temperature water. The rotating rod 4 is used to rotate the baffle plate 3 inside the low-temperature water pipe 1, thereby controlling the flow rate of the water. The disc 5 is used to rotate the rotating rod 4 more conveniently.

[0039] Reference Figure 3 One end of the rope 14 is fixedly connected to the outside of the rotating shaft 24, and the other end of the rope 14 is fixedly connected to the outside of the rotating rod 4. The rope 14 is used to wind around the rotating rod 4 as it rotates, so that the staff can roughly know the angle of rotation of the baffle plate 3.

[0040] Reference Figure 3 One end of the spring 13 is fixedly connected to the outside of the shaft 24, and the other end of the spring 13 is fixedly connected to the inner wall of the protective box 12. The spring 13 is used to wind up the rope 14, and the shaft 24 is used to support the rope 14 and the spring 13.

[0041] Working principle: High-temperature water enters through high-temperature water pipe 2, and low-temperature water enters through low-temperature water pipe 1, where heat exchange occurs. The water then flows out through outlet pipe 9. When the flow rate of the low-temperature water needs to be controlled, rotating disc 5 causes the rotating rod 4, which is fixed to disc 5, to rotate along with the baffle plate 3 inside the low-temperature water pipe 1, thus controlling the pipe opening size. As the disc 5 rotates, the rope 14, fixed to the rotating rod 4, winds around the outside of the rod 4, stretching the spring 13 in the protective box 12 and causing the rotating shaft 24 to rotate. A fixing rod 15 is fixed to the outside of the low-temperature water pipe 1, and the protective box 12 is fixed to the fixing rod 15. The number of turns of the rope 14 around the rotating rod 4 indicates the angle of rotation of the baffle plate 3. When rotation stops, the spring 13 in the protective box 12 contracts, causing the rotating shaft 24 to rotate in the opposite direction. Therefore, the rope 14 is retracted back to the outside of the rotating shaft 24, facilitating the operator's control of the flow rate of the low-temperature water inside the low-temperature water pipe 1. The flow rate of the water controls the temperature of the water outlet from the outlet pipe 9. After prolonged use, when the filter plate 7 needs to be replaced or cleaned, pull the pull ring 16. The pull ring 16 drives the pin 19, and the pad 18 fixed on the outside of the pin 19 slides inside the outer casing 21, thereby compressing the metal spring 17. The pull rod 20 is fixed on the outside of the pad 18, and the pull rod 20 slides inside the L-shaped groove 22 and the arc-shaped groove 23. When the pin 19 is pulled out of the filter plate 7, rotate the pin 19 so that the pull rod 20 is locked in the L-shaped groove 22. When the pin 19 is disengaged from the filter plate 7, pull the handle upward to pull the filter plate 7 out of the sealed box 8. When it is replaced or cleaned, insert the filter plate 7 back into the sealed box 8, and rotate the pin 19 so that it can slide inside the L-shaped groove 22. Under the action of the metal spring 17, the pin 19 is reinserted into the filter plate 7, which facilitates the replacement or cleaning of the filter plate 7 by the staff and saves manpower.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
