Description
Technical Field
[0001] This utility model relates to the field of volumetric heat exchanger technology, and in particular to a high-sealing volumetric heat exchanger. Background Technology
[0002] A volumetric heat exchanger is a heat exchanger that uses the alternating flow of cold and hot fluids across the surface of a heat storage body in a heat storage chamber to exchange heat. A partitioned volumetric heat exchanger is a heat exchanger in which the cold and hot fluids are separated by a solid partition and exchange heat through the partition. Therefore, it is also called a surface heat exchanger. It is widely used in many fields such as chemical, power, food, and pharmaceutical industries.
[0003] Existing hot and cold medium inlet and outlet pipes are usually installed on volumetric heat exchangers using bolt connections. During operation, the volumetric heat exchanger will vibrate, and the vibration force will be transmitted to the bolts, which can easily cause the bolts to loosen, thereby affecting the sealing performance of the volumetric heat exchanger.
[0004] Therefore, a high-sealing volumetric heat exchanger is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a high-sealing volumetric heat exchanger to solve the above-mentioned problems, thereby improving the problem that the volumetric heat exchanger will vibrate during operation, and the vibration force will be transmitted to the bolts, which can easily lead to the bolts loosening.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a high-sealing volumetric heat exchanger, comprising: a connecting pipe and a conveying pipe; and a reinforcing mechanism, the reinforcing mechanism including a first rubber frame and a second rubber frame disposed on the surface of the connecting pipe, a guide rod fixedly connected to the bottom of the second rubber frame, the surface of the guide rod being engaged with the inner wall of the first rubber frame, an arc-shaped block hinged to the surface of the guide rod, a limiting groove formed in the inner wall of the first rubber frame, a coil spring fixedly connected to the upper end of the surface of the arc-shaped block, the other end of the coil spring being fixedly connected to the inner wall of the second rubber frame, and a limiting block slidably connected to the inner wall of the second rubber frame. Through the cooperation of the guide rod and the coil spring, the top and bottom of the arc-shaped block abut against the limiting groove, thereby tightly connecting the first rubber frame and the second rubber frame. This causes the inner walls of the first and second rubber frames to tightly adhere to the ends of the bolts and nuts on the connecting pipe and the conveying pipe, wrapping the connection between the connecting pipe and the conveying pipe, thus locking the bolts and nuts and ensuring the high sealing performance of the volumetric heat exchanger.
[0007] Preferably, a shield is fixedly connected to the upper surface of the arc-shaped block, and the bottom end of the shield contacts the end of the second rubber frame. By shielding the opening at the end of the second rubber frame, impurities are prevented from falling onto the coil spring, ensuring the elastic force of the coil spring on the arc-shaped block, and thus ensuring that the arc-shaped block is stably pressed against the limiting groove.
[0008] Preferably, a pin is slidably connected to the inner wall of the second rubber frame, and the surface of the pin is engaged with the inner wall of the cover plate.
[0009] Preferably, a spring is fixedly connected to the bottom end of the pin, and the bottom end of the spring is fixedly connected to the inner wall of the second rubber frame. The elastic force of the spring pushes the pin upward and engages it inside the cover plate, thereby locking the cover plate, increasing the resistance to the rotation of the arc block, and ensuring a tight connection between the first rubber frame and the second rubber frame.
[0010] Preferably, two round rods are fixedly connected to the end of the second rubber frame. The rotation angle of the arc-shaped block is limited by the cooperation between the round rods and the cover plate, ensuring that the arc-shaped block can be accurately housed in the guide rod and accurately rotate to abut against the limiting groove.
[0011] Preferably, the bottom end of the pin is fixedly connected to a connecting rope, and the other end of the connecting rope passes through and extends out of the inner wall of the second rubber frame.
[0012] Preferably, one end of the connecting rope is fixedly connected to a connecting block.
[0013] The beneficial effects of this utility model are:
[0014] 1. Through the cooperation of the guide rod and the coil spring, the top and bottom of the arc-shaped block abut against the limiting groove, thereby making the first rubber frame and the second rubber frame tightly connected. This allows the inner walls of the first rubber frame and the second rubber frame to be tightly attached to the ends of the bolts and nuts on the connecting pipe and the conveying pipe, and to wrap the connection between the connecting pipe and the conveying pipe. Compared with the bolts on existing volumetric heat exchangers, which are easy to loosen and result in poor sealing performance, this method ensures the high sealing performance of the volumetric heat exchanger by locking the bolts and nuts.
[0015] 2. By blocking the opening at the end of the second rubber frame with a shielding plate, impurities are prevented from falling onto the coil spring, ensuring the elastic force of the coil spring on the arc-shaped block, and thus ensuring that the arc-shaped block is stably pressed against the limiting groove.

[0021] 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.
[0022] In practical implementation: such as Figure 1-4 As shown, a high-sealing volumetric heat exchanger includes: a connecting pipe 1 and a conveying pipe 2; a reinforcing mechanism 3, which includes a first rubber frame 31 and a second rubber frame 32 disposed on the surface of the connecting pipe 1. A guide rod 33 is fixedly connected to the bottom of the second rubber frame 32. The surface of the guide rod 33 is engaged with the inner wall of the first rubber frame 31. An arc-shaped block 34 is hinged to the surface of the guide rod 33. A limiting groove 35 is formed in the inner wall of the first rubber frame 31. A coil spring 37 is fixedly connected to the upper end of the surface of the arc-shaped block 34. The other end of the coil spring 37 is fixedly connected to the inner wall of the second rubber frame 32. A limiting block 36 is slidably connected to the inner wall of the second rubber frame 32.
[0023] One end of the connecting pipe 1 is fixedly connected to a volumetric heat exchanger. The upper surface of the volumetric heat exchanger is fixedly connected to a hot water outlet pipe and a cold water inlet pipe. The lower surface of the volumetric heat exchanger is fixedly connected to a drain pipe. The upper surface of the conveying pipe 2 is fixedly connected to a heat medium inlet pipe. The lower surface of the conveying pipe 2 is fixedly connected to a condensate outlet pipe.
[0024] Connect the connecting pipe 1 to the conveying pipe 2 using a flange connection. Connect the heat medium inlet pipe and the condensate outlet pipe on the conveying pipe 2 to the corresponding pipes. Connect the hot water outlet pipe, the cold water inlet pipe, and the sewage outlet pipe to the corresponding pipes.
[0025] After connecting pipe 1 and conveying pipe 2 are connected, the first rubber frame 31 and the second rubber frame 32 are respectively fitted onto the surfaces of connecting pipe 1 and conveying pipe 2, so that the ends of the first rubber frame 31 and the second rubber frame 32 abut against each other, and their inner walls abut against the ends of the bolts and nuts. After the guide rod 33 is engaged in the first rubber frame 31, the elastic force of the coil spring 37 pushes the arc block 34 to rotate, so that the top and bottom of the arc block 34 abut against the top wall and the bottom wall of the limiting groove 35. At this time, the limiting block 36 is pushed down into the limiting groove 35, so that the surface of the limiting block 36 abuts against the arc surface of the arc block 34, thereby locking the arc block 34 and tightly connecting the first rubber frame 31 and the second rubber frame 32, thereby wrapping and locking the connection between connecting pipe 1 and conveying pipe 2, and making connecting pipe 1 and conveying pipe 2 tightly connected.
[0026] Cold water is supplied to the volumetric heat exchanger through the cold water inlet pipe. The heat medium, such as steam or hot water, enters the volumetric heat exchanger through the heat medium inlet pipe. If the heat medium is steam, the steam will usually enter the heating coil set inside the volumetric heat exchanger; if it is hot water, it will flow into a special heat medium channel.
[0027] The heat of the heat medium is conducted to the heated medium in contact with the pipe wall through the heating coil or heat medium channel. Taking steam as the heat medium as an example, the steam releases latent heat in the heating coil and condenses into water. Its heat is transferred to the cold water outside the coil through the metal pipe wall. The heated cold water flows in the heat exchanger, forming natural convection or forced convection. When the cold water comes into contact with the heated pipe wall, its temperature rises and its density decreases, so it flows upward. The cold water at a lower temperature will replenish it, forming a circulating flow. This allows the cold water in the entire volume to continuously come into contact with the heating surface and absorb heat. In the process of continuous heat conduction and convection, the temperature of the heated medium gradually rises. Since the volumetric heat exchanger has a certain volume, the heated medium stays in the heat exchanger for a long time and can fully absorb the heat of the heat medium, thereby reaching a higher temperature. After the heat medium releases heat, its state changes.
[0028] If steam condenses into water, the temperature of the hot water decreases, and then it is discharged from the heat exchanger through the heat medium outlet pipe. The discharged heat medium can be recycled or further processed according to specific circumstances. The hot water heated to the set temperature is transported to the point of use through the hot water outlet pipe. At the same time, as hot water is output, cold water will continuously enter the heat exchanger from the cold water inlet pipe to continue the heat exchange process, so as to maintain a continuous supply of hot water.
[0029] like Figure 4As shown, a shield 38 is fixedly connected to the upper surface of the arc-shaped block 34. The bottom end of the shield 38 contacts the end of the second rubber frame 32. A pin 39 is slidably connected to the inner wall of the second rubber frame 32. The surface of the pin 39 is engaged with the inner wall of the shield 38. A spring 310 is fixedly connected to the bottom end of the pin 39. The bottom end of the spring 310 is fixedly connected to the inner wall of the second rubber frame 32. Two round rods 312 are fixedly connected to the end of the second rubber frame 32. The arc-shaped block 34, the limiting block 36, and the shield 38 are all rubber components.
[0030] The elastic force of the coil spring 37 drives the arc block 34 and the cover plate 38 to rotate. The surface of the cover plate 38 abuts against one of the round rods 312, stopping the rotation of the arc block 34 and the cover plate 38. At this time, the elastic force of the spring 310 pushes the pin 39 to move upward, so that the pin 39 is engaged in the cover plate 38, thereby locking the cover plate 38.
[0031] like Figure 3-4 As shown, a connecting rope 311 is fixedly connected to the bottom end of the pin 39, and the other end of the connecting rope 311 passes through and extends out of the inner wall of the second rubber frame 32. A connecting block 313 is fixedly connected to one end of the connecting rope 311.
[0032] Pulling the connecting block 313 will in turn pull the two connecting ropes 311, causing the pin 39 to move away from the cover plate 38. Pulling the two limiting blocks 36 will move the limiting blocks 36 away from the arc surface of the arc block 34, pushing the two cover plates 38 to abut against one of the round rods 312, causing the arc block 34 to rotate and be stored in the guide rod 33. At this time, pulling the second rubber frame 32 will separate the first rubber frame 31 from the second rubber frame 32.
[0033] In use, after the connecting pipe 1 is connected to the conveying pipe 2, the first rubber frame 31 and the second rubber frame 32 are respectively fitted onto the surfaces of the connecting pipe 1 and the conveying pipe 2, so that the ends of the first rubber frame 31 and the second rubber frame 32 abut against each other, and their inner walls abut against the ends of the bolts and nuts. After the guide rod 33 is engaged in the first rubber frame 31, the elastic force of the coil spring 37 pushes the arc-shaped block 34 to rotate, so that the top and bottom of the arc-shaped block 34 abut against the limiting groove. The inner top wall and inner bottom wall of 35 are connected. At this time, the limiting block 36 is pushed down into the limiting groove 35, so that the surface of the limiting block 36 abuts against the arc surface of the arc block 34. The elastic force of the spring 310 pushes the pin 39 up, so that the pin 39 is engaged in the cover plate 38, thereby locking the arc block 34, so that the first rubber frame 31 and the second rubber frame 32 are tightly connected, thereby wrapping and locking the connection between the connecting pipe 1 and the conveying pipe 2, so that the connecting pipe 1 and the conveying pipe 2 are tightly connected.
[0034] It should be noted that the connecting pipe 1, conveying pipe 2, volumetric heat exchanger, hot water outlet pipe, cold water inlet pipe, drain pipe, heat medium inlet pipe, condensate outlet pipe, etc. mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.
[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
