Description
Technical Field
[0001] This utility model relates to the field of jet heat exchange devices, and more particularly to a jet heat exchange device for improving the transport capacity of pipeline networks. Background Technology
[0002] A jet heat exchanger is a device that enhances the transport capacity of a pipeline network by injecting fluid power. It is widely used in heating, cooling, and industrial fluid transport. Its main structure includes an ejector, a heat exchanger, and a fluid guiding system, which can effectively improve heat exchange efficiency and ensure stable system operation.
[0003] However, in pipes carrying low-temperature water, the accumulation of scale in the water often reduces the inflow of low-temperature water, affecting the heat exchange process. Existing equipment often installs filters in the pipes to reduce the impact of scale, but due to the complex filter replacement process, scale will still accumulate on the filters after prolonged use, thus affecting heat exchange efficiency and the long-term reliability of the system.
[0004] To address the above problems, a jet-type heat exchange device is proposed to improve the pipeline transportation capacity. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a jet-type heat exchange device to improve the pipeline transportation capacity. It aims to solve the problem that due to the complicated filter replacement process, scale will still accumulate on the filter after long-term use, thus affecting the heat exchange efficiency and the long-term reliability of the system.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a jet-type heat exchange device for improving the transport capacity of a pipeline network, comprising:
[0007] The main cavity has an injection chamber installed at its left end, an inlet pipe fixedly connected to the top of the injection chamber, an inner cylinder installed above the inlet pipe, a filter screen installed inside the inner cylinder, and a mixing chamber threadedly connected to the right end of the main cavity, a mixing assembly installed inside the mixing chamber.
[0008] A quick-release assembly is used to quickly remove and replace the filter screen inside the inner cylinder. It is connected to the upper part of the inlet pipe via a flange. The quick-release assembly includes an inner cylinder with a groove on its outer side. A limiting cylinder is fixedly connected to the outer side of the groove. An outer cylinder is rotatably connected to the outer side of the limiting cylinder. Limiting blocks are slidably connected around the cavity between the groove and the limiting cylinder. A clamping block is fixedly connected to one end of the limiting block, and a pull rope is fixedly connected to the other end of the limiting block. A spring is sleeved on the outer side of the pull rope.
[0009] As a further description of the above technical solution:
[0010] The mixing assembly includes a mixing chamber, the outer left end of which is threaded to the inside of the main chamber. An exchange plate is fixedly connected to the inner left end of the mixing chamber. A connecting rod is rotatably connected to the middle of the exchange plate. Two impellers are fixedly connected to the outer side of the connecting rod.
[0011] As a further description of the above technical solution:
[0012] A water pipe is installed above the inner cylinder, and the water pipe is connected to the inner cylinder by a flange.
[0013] As a further description of the above technical solution:
[0014] The two adjacent flanges are fixedly connected by bolts and nuts.
[0015] As a further description of the above technical solution:
[0016] The side wall of the limiting cylinder has four holes, and the outer side of the pull rope is slidably connected to the inside of the holes.
[0017] As a further description of the above technical solution:
[0018] The left end of the spring is fixedly connected to the outside of the limiting block, and the right end of the spring is fixedly connected to the inner wall of the limiting cylinder.
[0019] As a further description of the above technical solution:
[0020] The outer side of the clamping block is slidably connected to the inside of the inner cylinder, and the opposite side of the four clamping blocks abuts against the side of the filter screen.
[0021] As a further description of the above technical solution:
[0022] The end of the pull rope away from the limiting block is fixedly connected to the inner wall of the outer cylinder.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, in order to ensure that the inflow of low-temperature water is not affected by scale, a filter screen is installed between the pipes. However, after a period of time, scale will also accumulate on the filter screen and affect the inflow of low-temperature water. Therefore, a quick-release assembly is used to fix the filter screen. When it needs to be replaced, simply rotate the outer cylinder and pull the limiting block inside the groove on the outer side of the inner cylinder to slide, so that the four clamping blocks no longer hold the filter screen. At this time, a new filter screen can be installed. After the outer cylinder is released, the clamping blocks will hold the filter screen again under the action of the four springs, which reduces the time required to replace the filter screen and thus ensures the heat exchange efficiency of the equipment.
[0025] 2. In this invention, after the high-temperature fluid and the low-temperature water come into contact in the main cavity, in order to ensure uniform mixing, the mixed water passes through multiple holes with different inclination angles on the exchange plate, and the two impellers intensify the degree of mixing, making the mixing between the fluids more thorough.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Reference Figure 1 - Figure 6 One embodiment of this utility model is a jet-type heat exchange device for improving the transport capacity of a pipeline network, comprising:
[0038] The main cavity 1 has an injection cavity 2 installed at the left end of the main cavity 1. An inlet pipe 4 is fixedly connected to the top of the injection cavity 2. An inner cylinder 6 is installed above the inlet pipe 4. A filter screen 14 is installed inside the inner cylinder 6. A mixing cavity 3 is threadedly connected to the right end of the main cavity 1. A mixing component is installed inside the mixing cavity 3.
[0039] The quick-release assembly is used for quickly removing and replacing the filter screen 14 inside the inner cylinder 6. It is connected to the top of the inlet pipe 4 via a flange 8. The quick-release assembly includes an inner cylinder 6, with a groove on the outer side of the inner cylinder 6. A limiting cylinder 9 is fixedly connected to the outer side of the groove, and an outer cylinder 7 is rotatably connected to the outer side of the limiting cylinder 9. Limiting blocks 12 are slidably connected around the cavity between the groove and the limiting cylinder 9. A clamping block 13 is fixedly connected to one end of the limiting block 12, and a pull rope 10 is fixedly connected to the other end of the limiting block 12. A spring 11 is sleeved on the outer side of the pull rope 10. A water pipe is installed above the inner cylinder 6. 5. The water pipe 5 is connected to the inner cylinder 6 by a flange 8. The two adjacent flanges 8 are fixedly connected by bolts and nuts. The side wall of the limiting cylinder 9 has four holes. The outer side of the pull rope 10 is slidably connected to the inside of the holes. The left end of the spring 11 is fixedly connected to the outer side of the limiting block 12. The right end of the spring 11 is fixedly connected to the inner wall of the limiting cylinder 9. The outer side of the clamping block 13 is slidably connected to the inside of the inner cylinder 6. The opposite side of the four clamping blocks 13 abuts against the side of the filter screen 14. The end of the pull rope 10 away from the limiting block 12 is fixedly connected to the inner wall of the outer cylinder 7.
[0040] Specifically, the injection chamber 2 sprays high-temperature, high-speed water into the main chamber 1. Since the internal volume of the injection chamber 2 is much larger than the left end connection of the main chamber 1, the fluid velocity increases significantly, resulting in lower pressure at the connection. An inlet pipe 4 is installed above the injection chamber 2. Due to the negative pressure, the low-temperature water in the inlet pipe 4 is drawn into the main chamber 1, achieving cooling. To ensure stable connections between the pipes, flanges 8 are installed between the inlet pipe 4, the inner cylinder 6, and the water pipe 5. These flanges 8 are secured together with bolts and nuts. A quick-release assembly is installed between the inlet pipe 4 and the water pipe 5 to allow for quick replacement and removal of the filter screen 14 inside the inner cylinder 6. Because the cooling water contains a large amount of scale, it accumulates significantly over time as it passes through the water pipe 5 and the inlet pipe 4, reducing the water intake and affecting heat exchange efficiency. Therefore, a filter screen 14 is installed in the inner cylinder 6 to filter the scale in the water to a certain extent. After a period of time, the filter screen 14 needs to be replaced. The quick-release assembly needs to be removed, and the outer cylinder 7 located on the outside is rotated. The four pull ropes 10 on the inner wall of the outer cylinder 7 will be pulled and drive the limiting block 12 at the other end of the pull rope 10. In the cavity between the inner cylinder 6 and the limiting cylinder 9, the spring 11 is compressed. The limiting block 12 drives the four clamping blocks 13 inside to slide in opposite directions. The limiting block 12 is restricted inside the cavity. At this time, the filter screen 14 in the middle of the clamping block 13 can be removed and replaced with a new one. After the outer cylinder 7 is released, the limiting block 12 is pushed back to its original position under the action of the four springs 11 and slides in opposite directions with the four clamping blocks 13 to hold the middle filter screen 14, thus completing the quick replacement of the filter screen 14 and ensuring the efficiency of the low temperature water intake.
[0041] Reference Figure 7 - Figure 8 The mixing assembly includes a mixing chamber 3. The left side of the mixing chamber 3 is threaded to the inside of the main chamber 1. An exchange plate 15 is fixedly connected to the left side of the mixing chamber 3. A connecting rod 16 is rotatably connected to the middle of the exchange plate 15. Two impellers 17 are fixedly connected to the outside of the connecting rod 16.
[0042] Specifically, in order to ensure uniform mixing between high-temperature water and low-temperature water, a mixing chamber 3 is threadedly connected to the right end of the main chamber 1. When the mixed water passes through the mixing chamber 3, it will first come into contact with the exchange plate 15. The exchange plate 15 has holes with different inclination directions. The mixed water will be diverted when passing through these holes and will be mixed more evenly due to the different directions. The water flow drives the two impellers 17 inside the mixing chamber 3, which are fixed by the connecting rod 16, to thoroughly turbid the mixed water, ensuring the uniformity of temperature throughout the mixed water and improving the heat exchange efficiency of the device.
[0043] Working Principle: To improve the heat exchange efficiency of the equipment, this device adopts Bernoulli's principle. High-temperature, high-speed fluid is injected into the main chamber 1 through the injection chamber 2. Due to the rapid narrowing of the space at the inlet of the main chamber 1, the fluid velocity increases while the pressure decreases, thereby drawing the low-temperature water in the inlet pipe 4 into the main chamber 1. No additional power is needed to inject low-temperature water. To ensure long-term operation of the equipment, a quick-release assembly is installed between the inlet pipe 4 and the water pipe 5. The filter screen 14 is fixed by the quick-release assembly to reduce the impact of scale in the water pipe 5 on the low-temperature water intake. To prevent scale buildup on the filter screen 14 from reducing the water intake, replacing the filter screen 14 only requires rotating the outer cylinder 7, which drives the four pull ropes 10 to pull the limit block 12. The limiting block 12 separates the four clamping blocks 13, allowing the filter screen 14 clamped in the middle to be removed and replaced with a new filter screen 14. After the outer cylinder 7 is released, the clamping blocks 13 will clamp the filter screen 14 again under the action of the four compressed springs 11, greatly reducing the time required to replace the filter screen 14 and thus improving the efficiency of heat exchange. In order to ensure uniform mixing between the high-temperature fluid and the low-temperature water, a mixing chamber 3 is threadedly connected to the right end of the main cavity 1. An exchange plate 15 is installed inside the mixing chamber 3. The exchange plate 15 has multiple inclined holes. When the mixed water flows through these holes, it will produce more thorough mixing, driving the two impellers 17 to rotate, further increasing the degree of mixing of the mixed water and ensuring the completion of heat exchange.
[0044] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
