Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of throttling heat exchangers, in particular to a heat exchanger integrated with a throttling device. BACKGROUND

[0002] In the industrial field, the tubular heat exchanger is a heat exchange equipment with extremely wide application, mainly using the tube bundle as the heat transfer surface, letting two fluids with different temperatures flow in the tube and shell respectively, and performing heat exchange through the tube wall. The heat exchanger integrated with a throttling device reduces the pressure inside the tubular heat exchanger by throttling the liquid.

[0003] The patent with the patent number CN223470553U discloses a high-efficiency high-sealing tubular heat exchanger, which comprises a high-efficiency tubular heat exchanger body, a conveying pipe, a sealing assembly and an auxiliary assembly. The high-efficiency tubular heat exchanger body is provided with a connecting pipe, and the connecting pipe is fixedly provided with a first flange plate. The conveying pipe is fixedly provided with a second flange plate, and the second flange plate and the first flange plate are provided with the sealing assembly and the auxiliary assembly. The second flange plate and the first flange plate are clamped and fixedly connected through bolts and nuts. The air ring is sleeved and arranged on the peripheral wall of the rubber pad. During the clamping process of the first flange plate and the second flange plate, the extrusion block extrudes the gas in the air bag into the air ring, so that the rubber pad is tightly attached to the flange plate. The sealing property of the device is improved. When the tubular heat exchanger conveys hot materials, the temperature of the pipe wall rises, the gas in the air ring is heated and expanded, the volume of the air ring increases, and the rubber pad is further extruded to tightly attach to the flange plate, thereby avoiding the loosening of the rubber pad and ensuring the sealing effect of the device.

[0004] However, the current high-efficiency high-sealing tubular heat exchanger has the following problems: during the use of the heat exchanger, the flow rate of the heat exchange water is too fast, which can easily cause the internal pressure of the heat exchanger body to be too large, thereby causing the deformation and damage of the internal parts of the heat exchanger body. During the throttling process of the heat exchanger, the funnel is easily vibrated and damaged by the impact of the heat exchange water flow. When the heat exchange water flows, it is easy to move the scale, thereby causing the drain pipe to be corroded and damaged by the scale. Therefore, we propose a heat exchanger integrated with a throttling device. SUMMARY

[0016] This invention provides a heat exchanger integrated with a throttling device. It has the following beneficial effects:

[0017] (1) The present invention uses a heat exchanger body, top cover, double ring frame, U-shaped tube, tank, drain pipe, electric hydraulic rod, ring mouth plate, funnel, ring plate and ring top plate in conjunction with a sliding rod. The telescopic end of the electric hydraulic rod drives the funnel to move downward, the funnel drives the ring plate to move downward, the ring plate enters the ring mouth plate, the ring plate blocks the hot water of the ring mouth plate, the funnel drives the ring top plate to move downward, the ring top plate drives the sliding rod to move downward, the sliding rod slides downward in the ring mouth plate, the hot water of the heat exchanger enters the funnel, the multiple outlets of the funnel flow out the hot water of the heat exchanger, the multiple outlets of the funnel limit the flow of the hot water of the heat exchanger to prevent the flow rate of the heat exchange water from being too fast and causing deformation and damage to the internal parts of the heat exchanger body.

[0018] (2) By setting up a vibration damping device, the short column, L-shaped block and cylinder work together with the spring. The ring top plate drives the short column to move downward, the L-shaped block supports the cylinder, the short column slides downward in the cylinder, and the short column pulls the spring to prevent the funnel from vibrating too much under the impact of hot water exchange, which would cause the funnel to be easily damaged by vibration.

The short column drives the bent rod to move downward, the bent rod drives the connecting plate to move downward, the connecting plate drives the rubber ring to move downward, and the rubber ring abuts against the gap between the ring plate and the ring plate to prevent water seepage at the gap between the ring plate and the ring plate, which would result in poor throttling effect.

[0020] (4) The present invention uses a filter device to make the U-shaped frame, square plate and ring shell cooperate with the filter screen. The bent rod drives the U-shaped frame to move downward, the U-shaped frame drives the square plate to move downward, the square plate drives the ring shell to move downward, and the ring shell drives the filter screen to move downward.

The ring shell drives the circumferential frame to move downward, the circumferential frame drives the thin rod to move downward, the thin rod slides downward in the fine hole of the L-shaped block, the thin rod drives the double arc plate to move downward, and the double arc plate limits the funnel to prevent the funnel from moving too deep downward in the ring plate, resulting in poor water blocking and throttling effect of the ring plate.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figures 1-8 One embodiment of the present invention is: a heat exchanger with an integrated throttling device, comprising: a heat exchanger body 1, a top cover 2 fixed on the top surface of the heat exchanger body 1, the heat exchanger body 1 comprising: a bottom cylinder 101, a long cylinder 102, heat exchange tubes 103 and a perforated plate 104, a water inlet is provided at the bottom right side of the bottom cylinder 101, the long cylinder 102 is fixed on the top surface of the bottom cylinder 101, a water inlet is provided at the top left side of the long cylinder 102, a water outlet is provided at the bottom left side of the long cylinder 102, a perforated plate 104 is fixed at the top of the inner wall of the long cylinder 102, a plurality of heat exchange tubes 103 are fixed on the inner wall of the perforated plate 104, another perforated plate 104 is fixed at the top of the outer wall of the plurality of heat exchange tubes 103, and the outer wall of the other perforated plate 104 is fixedly connected to the inner wall of the top cover 2;

[0033] Double-ring frame 3 is fixed to the outer wall of heat exchanger body 1. U-shaped tube 4 is fixed to the middle of the top surface of top cover 2. Tank body 5 is fixed to the end of U-shaped tube 4 away from top cover 2. The outer wall of tank body 5 is fixedly connected to the inner wall of double-ring frame 3. Drain pipe 6 is opened at the bottom right side of tank body 5. Electric hydraulic rod 7 is fixed to the middle of the bottom surface of tank body 5. The telescopic end of electric hydraulic rod 7 passes through and slides in the middle of the bottom surface of tank body 5. Ring plate 8, ring The inlet plate 8 is fixed to the lower inner wall of the tank body 5. The funnel 9 is fixed to the top surface of the telescopic end of the electric hydraulic rod 7. Several water outlets are opened at the bottom of the outer wall of the funnel 9. The ring plate 10 is fixed to the lower outer wall of the funnel 9. The ring top plate 11 is fixed to the top surface of the funnel 9. Sliding rods 12 are fixed on both sides of the bottom surface of the ring top plate 11. The bottom end of the sliding rod 12 penetrates and slides through the top surface of the ring inlet plate 8. The funnel 9 is used to throttle the drainage of the heat exchanger body 1.

[0034] The inner wall of the annular plate 8 is on the movement trajectory of the outer wall of the annular plate 10. Several outlets of the funnel 9 are set below the annular plate 10. Each slide rod 12 is provided with a limit block at its bottom end. The slide rod 12 is used to guide the funnel 9 to move downward. The tank body 5 is located on the right side of the heat exchanger body 1. The drain pipe 6 is located below the annular plate 8. The funnel 9 is located in the middle of the interior of the annular plate 8.

[0035] When using this equipment, the heat exchanger body 1 is supported by a double-ring frame 3, which in turn supports the tank body 5. The operator inputs hot water into the inlet of the long cylinder 102. The hot water enters the long cylinder 102 and heats the heat exchange tubes 103, causing the heat exchange tubes 103 on the perforated plate 104 to begin heating. The hot water flows downwards into the outlet of the long cylinder 102, where it is discharged. Simultaneously, the operator inputs cold water into the inlet of the bottom cylinder 101. The cold water rises into the heat exchange tubes 103, where it exchanges heat with the cold water. The exchanged hot water passes through the U-shaped tube 4 of the top cover 2 and flows downwards into the tank body 5. At the same time, the operator activates the electric hydraulic rod 7. The telescopic end of the heat exchanger begins to move downwards. The telescopic end of the electric hydraulic rod 7 drives the funnel 9 to move downwards. The funnel 9 drives the ring plate 10 to move downwards. The funnel 9 drives the ring top plate 11 to move downwards. The ring top plate 11 drives the slide rod 12 to move downwards. The slide rod 12 slides downwards in the ring mouth plate 8. The slide rod 12 is used to guide the funnel 9 to move downwards. The ring plate 10 enters the ring mouth plate 8. The ring plate 10 blocks the hot water exchange of the ring mouth plate 8. The hot water exchange enters the funnel 9. The hot water exchange flows out from the multiple outlets of the funnel 9. The multiple outlets of the funnel 9 limit the flow of the hot water exchange, thereby avoiding the problem of deformation and damage to the internal parts of the heat exchanger body 1 caused by the excessive flow rate of the heat exchange water during the use of the heat exchanger.

[0036] Vibration damping devices 13 are provided on both sides of the top surface of the ring plate 11. The vibration damping devices 13 are used to reduce the vibration amplitude of the funnel 9 under the impact of water flow. A filter device 14 is provided on the outer wall of the vibration damping device 13. The filter device 14 is used to filter out scale in the water exchange.

[0037] Working principle: The heat exchanger body 1 supports the double-ring frame 3, which in turn supports the tank body 5. Hot water is input into the inlet of the long cylinder 102, heating the heat exchange tubes 103. The heat exchange tubes 103 on the perforated plate 104 begin to heat up, and hot water is discharged from the outlet of the long cylinder 102. Cold water is input into the inlet of the bottom cylinder 101, rising into the heat exchange tubes 103, where it exchanges heat with the cold water. The exchanged hot water then passes through the U-shaped tube 4 of the top cover 2. As the water flows downward into the tank 5, the telescopic end of the electric hydraulic rod 7 moves the funnel 9 downward. The funnel 9 moves the ring plate 10 downward, and the funnel 9 moves the ring top plate 11 downward. The ring top plate 11 moves the sliding rod 12 downward, and the sliding rod 12 slides downward in the ring opening plate 8. The ring plate 10 enters the ring opening plate 8 and blocks the hot water exchange of the ring opening plate 8. The hot water exchange enters the funnel 9, and the multiple outlets of the funnel 9 flow out the hot water exchange, thus limiting the flow of the hot water exchange.

[0038] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the vibration damping device 13 includes: two short columns 131, which are fixed on both sides of the top surface of the ring top plate 11; two L-shaped blocks 132, which are fixed above the inner wall of the tank 5; each of the two L-shaped blocks 132 has a small hole on its top surface; two cylinders 133, which are respectively inserted through and fixed in the middle of the top surface of the two L-shaped blocks 132; the inner wall of the two cylinders 133 slides in contact with the outer wall of the two short columns 131; and a spring 134 is respectively provided between the top of the two short columns 131 and the inner top of the two cylinders 133. The short columns 131 reduce the vibration amplitude of the funnel 9 under the impact of water flow by the elastic force of the springs 134 when they are stretched.

[0039] As the funnel 9 moves downward along with the ring top plate 11, the ring top plate 11 moves downward along with the short column 131. At the same time, the tank body 5 supports the L-shaped block 132, which in turn supports the cylinder 133. The short column 131 slides downward within the cylinder 133, pulling the spring 134. Under the elastic force of the spring 134, the vibration amplitude of the funnel 9 as it moves downward is reduced, thus avoiding the problem of the funnel 9 being easily damaged by vibration due to excessive amplitude under the impact of the hot water during the use of the heat exchanger.

[0040] A bent rod 135 is passed through and fixed to the bottom of the outer wall of each of the two short columns 131. A connecting plate 136 is fixed to the end of each of the two bent rods 135 that is close to each other. A rubber ring 137 is fixed to the bottom surface of the two connecting plates 136. The rubber ring 137 is located above the ring plate 10.

[0041] As the short column 131 slides downwards within the cylinder 133, it drives the bent rod 135 to move downwards. The bent rod 135 then drives the connecting plate 136 to move downwards, which in turn drives the rubber ring 137 to move downwards. During this downward movement, the rubber ring 137 rests against the gap between the annular plate 8 and the annular plate 10, thus preventing water leakage at the gap between the annular plate 8 and the annular plate 10 during heat exchanger operation, which would otherwise result in poor throttling performance.

[0042] The filter device 14 includes: two U-shaped frames 141, which are respectively fixed on the outer walls of two bent rods 135; two square plates 142, which are respectively fixed in the middle of the two U-shaped frames 141 on the side close to each other; an annular shell 143, which is fixed on the side close to each other of the two square plates 142; and a filter screen 144, which is fixed to the bottom of the inner wall of the annular shell 143. The filter screen 144 is used to filter scale in the water exchanged.

[0043] As the bent rod 135 moves the connecting plate 136 downward, the bent rod 135 also moves the U-shaped frame 141 downward. The U-shaped frame 141 moves the square plate 142 downward, the square plate 142 moves the ring shell 143 downward, and the ring shell 143 moves the filter screen 144 downward. The filter screen 144 is located above the ring top plate 11. The filter screen 144 filters the scale in the exchange water, thereby avoiding the problem of scale corrosion and damage to the drain pipe 6 caused by the heat exchange water moving with the scale during the use of the heat exchanger.

[0044] The top surface of the ring shell 143 is embedded with a spiral frame 145 on both sides. A thin rod 146 is fixed on the top surface of the spiral frame 145 respectively. The outer walls of the two thin rods 146 slide in contact with the inner walls of the holes of the two L-shaped blocks 132. A double arc plate 147 is fixed at the top of the two thin rods 146 respectively. The double arc plate 147 is used to limit the downward movement of the funnel 9.

[0045] As the square plate 142 moves the annular shell 143 downward, the annular shell 143 moves the circular frame 145 downward, and the circular frame 145 moves the thin rod 146 downward. The thin rod 146 slides downward in the small hole of the L-shaped block 132, and the thin rod 146 moves the double arc plate 147 downward. During the downward movement, the double arc plate 147 contacts the top of the L-shaped block 132. The double arc plate 147 limits the funnel 9, thereby avoiding the problem that the funnel 9 moves too deep downward in the annular plate 8 during the use of the heat exchanger, which would cause the annular plate 10 to have a poor water blocking and throttling effect.

[0046] Working principle: The ring top plate 11 drives the short column 131 to move downward, the L-shaped block 132 supports the cylinder 133, the short column 131 slides downward in the cylinder 133, and the short column 131 pulls the spring 134.

[0047] The short column 131 drives the bent rod 135 to move downward, the bent rod 135 drives the connecting plate 136 to move downward, the connecting plate 136 drives the rubber ring 137 to move downward, and the rubber ring 137 abuts against the gap between the ring plate 8 and the ring plate 10 during the downward movement.

[0048] The bent rod 135 drives the U-shaped frame 141 to move downward, the U-shaped frame 141 drives the square plate 142 to move downward, the square plate 142 drives the ring shell 143 to move downward, the ring shell 143 drives the filter screen 144 to move downward, and the filter screen 144 filters and exchanges the scale in the water.

[0049] The ring shell 143 drives the ring frame 145 to move downward, the ring frame 145 drives the thin rod 146 to move downward, the thin rod 146 slides downward in the small hole of the L-shaped block 132, the thin rod 146 drives the double arc plate 147 to move downward, and the double arc plate 147 contacts the top of the L-shaped block 132 during the downward movement.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
