Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a mixing water heat exchange device for adjusting the terminal heating effect. Background Technology

[0002] A mixing heat exchanger is a key device that achieves terminal heating regulation through temperature mixing and heat exchange.

[0003] In traditional mixing heat exchangers that regulate the effect of terminal heating, staff mix the high-temperature hot water from the primary network with the low-temperature return water from the secondary network by setting up simple pipe connections. The mixture is then transported to the terminal heating equipment through the secondary water supply pipe. However, in actual use, after the high-temperature hot water from the primary network and the low-temperature return water from the secondary network enter the mixing tank directly through the delivery pipe, the water flow is disordered. This may result in the high-temperature hot water flowing directly to the secondary network supply pipe without sufficient contact with the low-temperature return water. Furthermore, the disordered water flow will create a large number of dead zones in the mixing tank, which can easily lead to the accumulation of impurities over time. This may reduce heat exchange efficiency and even cause pipe blockage, thereby significantly shortening the equipment's lifespan and increasing maintenance costs and frequency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixing heat exchange device for adjusting the terminal heating effect. It solves the problem that in actual use, when high-temperature hot water from the primary network and low-temperature return water from the secondary network directly enter the mixing tank through the delivery pipe, the water flow is disordered. This can lead to the high-temperature hot water flowing directly to the secondary network supply pipe without sufficient contact with the low-temperature return water. Furthermore, the disordered water flow can create numerous dead zones within the mixing tank, which can easily lead to impurity accumulation over time, potentially reducing heat exchange efficiency and even causing pipe blockage. This significantly shortens the equipment's lifespan and increases maintenance costs and frequency.

[0010] This utility model provides a mixing heat exchange device for adjusting the terminal heating effect. It has the following beneficial effects: Through the cooperation of a guide pipe, a slide, a guide plate, and a turbulence block, the primary network hot water forms a spiral flow under the guidance of the guide plate, extending the contact path and time between the primary network hot water and the secondary network return water. This ensures sufficient counter-current contact with the secondary network return water, significantly improving the mixing effect and guaranteeing the stability of the secondary network water supply temperature.

[0011] The adjustment of the guide plate is fixed by the combination of bolts, clamping plates, fixing plates and rubber pads, which ensures that the entire guide structure can work stably.

[0014] 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.

[0015] In actual use, the high-temperature hot water from the primary network and the low-temperature return water from the secondary network enter the mixing tank directly through the delivery pipes. The water flow is disordered, which may result in the high-temperature hot water flowing directly to the secondary network supply pipe without sufficient contact with the low-temperature return water. Furthermore, the disordered water flow will create a large number of dead zones in the mixing tank. Long-term use can easily lead to the accumulation of impurities, which may reduce heat exchange efficiency and even cause pipe blockage, thereby significantly shortening the service life of the equipment and increasing maintenance costs and frequency.

[0016] In view of this, the present invention provides a mixing heat exchange device for adjusting the terminal heating effect. This mixing heat exchange device, through the cooperation of a guide pipe, a slide, a guide plate and a turbulence block, causes the primary network hot water to form a spiral water flow under the guidance of the guide plate, extending the contact path and time between the primary network hot water and the secondary network return water, ensuring sufficient reverse contact with the secondary network return water, significantly improving the mixing effect and ensuring the stability of the secondary network water supply temperature.

[0017] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0018] Example 1, by Figure 1-5It is known that a mixing water heat exchange device for adjusting the terminal heating effect includes a mixing tank 1, the top of the mixing tank 1 is connected to a primary network inlet valve 2, a guide pipe 3 is provided inside the mixing tank 1, the top of the guide pipe 3 is fixedly connected to the bottom of the primary network inlet valve 2, a slide 4 is provided below the guide pipe 3, the slide 4 is fixedly connected to the inner wall of the mixing tank 1, a guide plate 5 is slidably connected to the inner wall of the slide 4, and a turbulence block 6 is fixedly connected to the inner wall of the guide plate 5. In the specific implementation process, it is worth noting that the mixing tank 1 is generally cylindrical, and its material can be high-strength alloy steel. Its inner wall is coated with an epoxy resin anti-corrosion layer. A sealing cap, made of the same material as the mixing tank 1, is fixed to its top with multiple screws. A waterproof temperature sensor, model WZP-230, is installed on its inner wall to monitor the internal temperature of the mixing tank 1. The primary network inlet valve 2 can be a Z41H-16C type electric gate valve. The input end of the primary network inlet valve 2 is connected to an external high-temperature hot water source. The guide pipe 3 is fixedly connected to the output end of the primary network inlet valve 2 via a flange. Its material can be stainless steel, and the end of the guide pipe 3 faces the tangential direction of the inner wall of the mixing tank 1, allowing water to flow... A swirling flow is formed along the tank wall, extending the residence time inside the tank. The slide 4 is spiral-shaped all the way to the bottom of the mixing tank 1. Its material can be stainless steel. Multiple guide plates 5 are provided, spirally distributed along the inner wall of the mixing tank 1. Their cross-section is similar to a 'U' shape. 'T' shaped blocks are provided on their side walls, which can move inside the slide 4. Multiple turbulence blocks 6 are provided. Their overall shape is similar to a cone. Their material can be silicon carbide ceramic. In actual operation, after the high-temperature hot water from the primary network enters the mixing tank 1 through the primary network inlet valve 2, it forms a spiral water flow under the guidance of the guide plates 5. It is fully mixed with the low-temperature return water entering from the secondary network return pipe. Furthermore, the turbulence blocks 6 on the guide plates 5 can further enhance the turbulence of the water flow and improve the mixing effect. Furthermore, a bolt 7 is installed inside the slide 4, and a clamping plate 8 is threadedly connected to the outer wall of the bolt 7. The top of the clamping plate 8 is pressed against the top of the inner wall of the slide 4, and the side wall of the clamping plate 8 is attached to the outer wall of the guide plate 5. A fixing plate 9 is installed below the clamping plate 8. The fixing plate 9 is fixedly connected to the bottom of the bolt 7, and a rubber pad 10 is fixedly connected to the bottom of the fixing plate 9. The rubber pad 10 is pressed against the bottom of the inner wall of the slide 4. In the specific implementation process, it is worth noting that multiple bolts 7 are provided, and their material can be selected as 35CrMoA high-strength bolts. Their outer walls can be coated with Dacromet coating, and protective covers can be added to their nuts. The protective covers can be made of silicone rubber to cover the outside and reduce water corrosion. When bolts 7 need to be adjusted, the protective covers can be removed. The clamping plate 8 has an 'n'-shaped cross section and can be made of stainless steel. The number of plates is the same as that of bolts 7, and an internal thread is provided at the top center. The fixing plate 9 is generally similar to a circular plate. Its material is the same as that of the clamping plate 8, and the shape of the rubber pad 10 is the same as that of the fixing plate 9. Its material can be silicone rubber. The rubber pad 10 increases the friction between the fixing plate 9 and the inner wall of the slide 4. During processing, the operator threads the clamping plate 8 to the outer wall of the bolt 7, then fixes the fixing plate 9 to the bottom of the bolt 7, and finally fixes the rubber pad 10 to the bottom of the fixing plate 9. When actually installing the guide plate 5, the operator needs to slide a pre-processed bolt 7 through the port of the slide 4 into the interior of the slide 4, and then... Plate 5 is installed onto slide rail 4. Then, a pre-machined bolt 7 is slid along the inner wall of slide rail 4 to the other end of guide plate 5. At this point, both ends of guide plate 5 are equipped with bolts 7 with clamping plates 8. The operator then rotates bolt 7 counterclockwise. Initially, clamping plate 8 is close to fixed plate 9. As bolt 7 rotates, clamping plate 8 rises until its top presses against the inner wall of slide rail 4. Then, by moving bolt 7 at the other end of guide plate 5, bolt 7 moves clamping plate 8, fixed plate 9, and rubber pad 1. Move the guide plate 5 by pressing the clamping plate 8 until the outer wall of the guide plate 5 is in contact with the clamping plate 8 on the first bolt 7. Then, repeat the previous action to fix the clamping plate 8 on the second bolt 7, thereby ensuring that the position of the guide plate 5 is locked. The same applies to the other guide plates 5. When it is necessary to adjust the position of the guide plate 5, rotate the bolt 7 clockwise. The clamping plate 8 moves downward and away from the top of the inner wall of the slide 4, thereby unlocking it. After unlocking, it can be adjusted. This improves the stability of the guide plate 5 and ensures the guiding effect. Furthermore, a controller 11 is fixedly connected to the top of the mixing tank 1 near the primary network inlet valve 2, and a pressure gauge 12 is installed on the outer wall of the controller 11 away from the primary network inlet valve 2. In the specific implementation process, it is worth noting that the controller 11 can be used to control the inlet and outlet valves of the entire mixing tank 1. The model of the controller 11 can be S7-200-SMART-PLC, and the pressure gauge 12 is YTN-100Z digital remote transmission type, which can work with the controller 11 to monitor the internal pressure of the mixing tank 1. At the same time, the controller 11 is also connected to its internal temperature sensor to monitor the internal temperature of the mixing tank 1, thereby improving the convenience and safety of the mixing heat exchange device for improving the heating effect of the regulating terminal. Example 2, by Figure 1-5 It can be seen that the side wall of the mixing tank 1 is connected to the secondary network water supply valve 13; In the specific implementation process, it is worth noting that the secondary network water supply valve 13 is connected to the side wall of the mixing tank 1 and is used to output the mixed medium-temperature water to the end. Its model can be selected as ZDLP-16P electric regulating valve. A water temperature sensor can be added to its output end to monitor the temperature of the mixed water. Its setting on the side wall can adapt to the internal flow field of the mixing tank 1 and improve the heat exchange uniformity. Furthermore, a secondary network return valve 14 is connected to the bottom of the mixing tank 1, and a flow guide shroud 15 is fixedly connected to the top of the secondary network return valve 14. The flow guide shroud 15 is located inside the mixing tank 1, and support legs 16 are provided around the secondary network return valve 14. The support legs 16 are fixedly connected to the bottom of the mixing tank 1. In the specific implementation process, it is worth noting that the secondary network return water valve 14 is used to connect the low-temperature return water after the end heat dissipation. Its model can be H44H-16C type check valve. The flow guide shroud 15 is fixedly connected to the output end of the secondary network return water valve 14 through the flange. Its overall shape is similar to a horn. Its material can be stainless steel. Its large end faces the inside of the mixing tank 1, which can make the secondary network return water evenly dispersed and better mixed with the spiral water flow, eliminating water flow dead corners, reducing water flow resistance, and improving the overall heat exchange efficiency. The support leg 16 provides support for the entire device and ensures the stability of the device. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
