Description

Technical Field

[0001] The invention relates to the technical field of heat insulation covers for plate heat exchangers, in particular to an intelligent temperature control and heat insulation instrument cover for plate heat exchangers. Background Art

[0002] The plate heat exchanger is mainly composed of heat transfer plates, sealing gaskets, pressure plates, clamping bolts, upper and lower guide rods and other components. The heat transfer plate is the core component and is usually corrugated in shape. Its working principle is based on heat conduction. Two fluids of different temperatures flow in the channels on both sides of the plate. When the hot fluid and the cold fluid flow through adjacent plate channels, heat is transferred from the hot fluid to the cold fluid through the plates. For example, in a plate heat exchanger, hot water flows in the channel on one side of the plate and cold water flows in the channel on the other side. The heat of the hot water will be transferred to the cold water through the plate metal, causing the cold water temperature to rise and the hot water temperature to fall, thereby realizing heat exchange.

[0003] If the heat exchanger does not have an insulation cover, heat will be lost to the surrounding environment through the heat exchanger shell and connecting pipes, and under high-temperature working conditions, the surface temperature of the plate heat exchanger may be very high. If people accidentally touch the heat exchanger shell, scalding accidents may occur.

[0004] Existing insulation covers are usually multi-layer composite structure insulation covers, consisting of an inner insulation layer, a middle insulation layer and an outer protective layer. Although the insulation cover can play a certain role in heat insulation, when the ambient temperature is too low, the rate of heat loss from the heat exchanger through the insulation cover to the surrounding environment will still increase, which means that the heat exchanger needs to consume more energy to maintain the temperature of the internal fluid in order to complete the established heat exchange task, resulting in reduced energy utilization efficiency and increased operating costs.

[0005] Moreover, the water outlet and water inlet of the plate heat exchanger are usually made of a variety of materials, such as metal interface components (such as pipes, flanges) and non-metallic sealing gaskets. The thermal expansion coefficients of these materials are different. When the temperature changes, they expand or contract to different degrees, resulting in stress and gaps at the interfaces, and then varying degrees of water leakage, which drips onto the surface of the insulation cover. Since some insulation covers are made of metal, they will corrode under the long-term action of water leakage. The insulation cover made of carbon steel will undergo oxidation reaction and rust in an environment with water and oxygen. At the same time, impurities such as rust produced by corrosion may fall into the plate heat exchanger through the gaps in the insulation cover, affecting the purity of the fluid inside the heat exchanger.

[0006] Therefore, it is necessary to design a plate heat exchanger insulation instrument cover with intelligent temperature control and automatic anti-leakage measures. Summary of the Invention

[0007] The object of the present invention is to provide an intelligent temperature-control and heat-insulating instrument cover for a plate heat exchanger, so as to solve the problems raised in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligent temperature-controlled and heat-insulating instrument cover for a plate heat exchanger, comprising a front heat-insulating mechanism, a magnetic plate provided on one side of the front heat-insulating mechanism, a rear heat-insulating mechanism provided on one side of the magnetic plate, a temperature sensor provided on one side of the rear heat-insulating mechanism for monitoring the temperature around the heat-insulating cover, a plate heat exchanger provided inside the front heat-insulating mechanism and the rear heat-insulating mechanism, and four groups of water-proof mechanisms for preventing continuous water leakage to the surface of the heat-insulating cover evenly provided on the other side of the front heat-insulating mechanism.

[0009] According to the above technical solution, the rear insulation mechanism includes a first protective layer, the first protective layer is fixedly connected to the temperature sensor, the inner side of the first protective layer is fixedly connected to a first rock wool layer, the interior of the first rock wool layer is evenly fixedly connected to three first heating plates, the inner side of the first rock wool layer is fixedly connected to a first thermal insulation layer, the interior of the first protective layer, the first rock wool layer and the first thermal insulation layer are evenly provided with a number of first bolt through holes, and the first protective layer and the magnetic attraction plate are magnetically connected.

[0010] According to the above technical solution, the front insulation mechanism includes a second protective layer magnetically connected to the other side of the magnetic attraction plate, the inner side of the second protective layer is fixedly connected to a second rock wool layer, the interior of the second rock wool layer is evenly fixedly connected to three second heating plates, the inner side of the second rock wool layer is fixedly connected to a second thermal insulation layer, the second protective layer, the second rock wool layer and the second thermal insulation layer are evenly provided with four water inlet and outlet holes, the second protective layer, the second rock wool layer and the second thermal insulation layer are evenly provided with a number of second bolt through holes, and one side of the second protective layer is evenly provided with a number of horizontal sliding grooves and vertical sliding grooves.

[0011] According to the above technical solution, the water leakage prevention mechanism includes a second curved slide that is slidably connected to one side of one of the transverse sliding grooves, wherein one side of the other transverse sliding groove is slidably connected to the first curved slide, the inner side of the first curved slide is fixedly connected to the first curved rubber plate, the inner side of the second curved slide is fixedly connected to the second curved rubber plate, the lower side of the second curved slide is fixedly connected to the first positioning plate, the lower side of the first curved slide is fixedly connected to the second positioning plate, one side of the first positioning plate is fixedly connected to the first tooth plate, one side of the second positioning plate is fixedly connected to the second tooth plate, and the lower side of the second tooth plate is provided with a collection component for collecting dripping water and using the gravity of the water source to seal the leaking area.

[0012] According to the above technical solution, an inclined groove is provided inside the first tooth plate, and the collecting assembly includes a water supply pipe fixedly connected to the lowest end of the inclined groove, and a collecting assembly is slidably connected to one side of the vertical slide groove.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-7 The present invention provides a technical solution: an intelligent temperature control and insulation instrument cover for a plate heat exchanger, comprising a front insulation mechanism 1, a magnetic plate 4 is provided on one side of the front insulation mechanism 1, a rear insulation mechanism 3 is provided on one side of the magnetic plate 4, a temperature sensor 2 for monitoring the temperature around the insulation cover is provided on one side of the rear insulation mechanism 3, a plate heat exchanger 5 is provided inside the front insulation mechanism 1 and the rear insulation mechanism 3, and four groups of anti-leakage mechanisms 6 for preventing continuous water leakage to the surface of the insulation cover are evenly provided on the other side of the front insulation mechanism 1.

[0018] Supplementary explanation based on the above structure is as follows: the front insulation mechanism 1 and the rear insulation mechanism 3 are used to be assembled on the front and rear sides of the plate heat exchanger 5 respectively, and the magnetic plate 4 is used to attract the front insulation mechanism 1 and the rear insulation mechanism 3, so that the front insulation mechanism 1 and the rear insulation mechanism 3 are assembled together, thereby making the front insulation mechanism 1 and the rear insulation mechanism 3 convenient to disassemble and assemble, and the temperature sensor 2 can be a thermistor temperature sensor. The thermistor is a sensitive element whose resistance value changes with temperature. The thermistor temperature sensor is generally made of semiconductor material. When the ambient temperature rises, the number of carriers in the semiconductor material increases, resulting in a decrease in resistance value; and when the ambient temperature decreases, the number of carriers decreases and the resistance value increases.

[0019] See also Figure 2 The rear insulation mechanism 3 includes a first protective layer 31, which is fixedly connected to the temperature sensor 2. The inner side of the first protective layer 31 is fixedly connected to a first rock wool layer 32. The inside of the first rock wool layer 32 is evenly fixedly connected with three first heating plates 35. The inner side of the first rock wool layer 32 is fixedly connected with a first thermal insulation layer 33. Several first bolt through holes 34 are evenly provided inside the first protective layer 31, the first rock wool layer 32 and the first thermal insulation layer 33. The first protective layer 31 and the magnetic attraction plate 4 are magnetically connected.

[0020] See also Figure 3-Figure 5 The front insulation mechanism 1 includes a second protective layer 11 magnetically connected to the other side of the magnetic attraction plate 4, a second rock wool layer 12 is fixedly connected to the inner side of the second protective layer 11, three second heating plates 14 are evenly fixedly connected to the inside of the second rock wool layer 12, a second thermal insulation layer 13 is fixedly connected to the inner side of the second rock wool layer 12, four water inlet and outlet holes 16 are evenly provided inside the second protective layer 11, the second rock wool layer 12 and the second thermal insulation layer 13, a number of second bolt through holes 15 are evenly provided inside the second protective layer 11, the second rock wool layer 12 and the second thermal insulation layer 13, and a number of horizontal sliding grooves 111 and vertical sliding grooves 112 are evenly provided on one side of the second protective layer 11.

[0021] Supplementary explanations based on the above structure are as follows: the first protective layer 31 and the second protective layer 11 are metal protective layers, which have high strength and hardness, and can resist mechanical effects such as collision, friction, and extrusion of external objects on the insulation layer, thereby avoiding damage to the insulation material due to external forces, thereby extending the service life of the insulation layer. The metal protective layer generally has a lower thermal conductivity, which can reduce the loss of heat through the insulation cover and play a certain role in heat insulation. Although its heat insulation effect is not as good as the internal insulation material, it can also enhance the heat insulation performance of the entire insulation cover to a certain extent.

[0022] The first rock wool layer 32 and the second rock wool layer 12 are rock wool, which is a high-quality thermal insulation material with a low thermal conductivity. It can effectively prevent the internal heat of the plate heat exchanger 5 from being lost to the surrounding environment, improve the energy utilization efficiency of the heat exchanger, and reduce energy consumption. Through its good thermal insulation performance, the rock wool layer helps to maintain the stability of the internal temperature of the plate heat exchanger 5 and reduce the impact of external environmental temperature fluctuations on the operating temperature of the heat exchanger, thereby ensuring the heat exchange effect and operating efficiency of the heat exchanger, enabling it to operate under more stable working conditions.

[0023] The first heat insulation layer 33 and the second heat insulation layer 13 are inner heat insulation layers, which are generally made of materials such as high-temperature resistant fireproof cloth, and can effectively block heat transfer.

[0024] The plate heat exchanger 5 usually has complex flow channels and sealing structures inside. If the fluid temperature is too low and freezes, the volume will expand, which may generate huge pressure on the plates, pipes, sealing gaskets and other components of the heat exchanger, causing the equipment to freeze and crack and be damaged. The heating effect of the first heating plate 35 and the second heating plate 14 can ensure that the fluid is in a flowing state, prevent damage to the equipment due to freezing, and extend the service life of the equipment.

[0025] The first bolt through-holes 34 and the second bolt through-holes 15 are used for passing bolts of the plate heat exchanger 5 , and the inlet and outlet water through-holes 16 are used for passing inlet and outlet water pipes of the plate heat exchanger 5 .

[0026] See also Figure 6 The anti-leakage mechanism 6 includes a second arc-shaped slide 63 slidably connected to one side of one of the transverse sliding grooves 111, wherein the first arc-shaped slide 62 is slidably connected to one side of the other transverse sliding groove 111, the inner side of the first arc-shaped slide 62 is fixedly connected to the first arc-shaped rubber plate 61, the inner side of the second arc-shaped slide 63 is fixedly connected to the second arc-shaped rubber plate 64, the lower side of the second arc-shaped slide 63 is fixedly connected to the first positioning plate 65, the lower side of the first arc-shaped slide 62 is fixedly connected to the second positioning plate 67, one side of the first positioning plate 65 is fixedly connected to the first tooth plate 66, one side of the second positioning plate 67 is fixedly connected to the second tooth plate 68, and the lower side of the second tooth plate 68 is provided with a collecting component 69 for collecting dripping water and using the gravity of the water source to seal the leaking area.

[0027] Supplementary explanation based on the above structure is as follows: the rotation of the gear 692 is used to drive the first tooth plate 66 and the second tooth plate 68 to move, thereby driving the second arc-shaped slide plate 63 and the first arc-shaped slide plate 62 to slide respectively, driving the first arc-shaped rubber plate 61 and the second arc-shaped rubber plate 64 to approach the flange connection at the same time, thereby controlling the first arc-shaped rubber plate 61 and the second arc-shaped rubber plate 64 to wrap the connection seam of the two flanges.

[0028] See also Figure 7The first tooth plate 66 is provided with an inclined groove 661 inside, and the collecting component 69 includes a water supply pipe 691 fixedly connected to the lowest end of the inclined groove 661. The collecting component 69 is slidably connected to one side of the vertical slide 112. A gear 692 is meshed and connected in the middle of the first tooth plate 66 and the second tooth plate 68. A rotating shaft 695 is fixedly connected in the middle of the gear 692. One end of the rotating shaft 695 is rotatably connected to the second protective layer 11 and the other end is fixedly connected to the I-wheel 693. A steel wire rope 694 is fixedly connected to the outside of the I-wheel 693. The steel wire rope 694 is wound around the outside of the I-wheel 693 for three-quarters of a circle. The other end of the steel wire rope 694 is fixedly connected to the water collecting tank 696.

[0029] Supplementary explanation based on the above structure is as follows: the interior of the water collecting tank 696 is used to store dripping water to prevent the water from dripping onto the surface of the insulation cover. The water collecting tank 696 can slide up and down along the vertical slide groove 112, and the gear 692 generates friction with the first gear plate 66 and the second gear plate 68 respectively. Since the gravity of the water collecting tank 696 without water is less than the friction between the gear 692 and the first gear plate 66 and the second gear plate 68, the water collecting tank 696 without water will not slide downward and drive the I-wheel 693 to rotate.

[0030] When the plate heat exchanger 5 needs to be insulated, the insulation cover is installed on the outside of the plate heat exchanger 5, and the temperature sensor 2 monitors the ambient temperature outside the insulation cover in real time. According to the ambient temperature outside, the heating power of the first heating plate 35 and the second heating plate 14 is controlled.

[0031] When the temperature outside monitored by the temperature sensor 2 is lower than or equal to zero degrees, the first heating plate 35 and the second heating plate 14 perform high-power heating, thereby increasing the ambient temperature around the plate heat exchanger 5 and preventing the fluid inside the plate heat exchanger 5 from freezing.

[0032] When the temperature outside monitored by the temperature sensor 2 is higher than zero degrees and lower than or equal to thirty degrees, the first heating plate 35 and the second heating plate 14 perform low-power heating. The heat generated by the heating plates can increase the temperature inside the insulation cover and enhance the insulation performance of the insulation cover. When the temperature inside the insulation cover rises, the temperature difference between the inside and outside decreases, and the rate of heat loss will also slow down.

[0033] When the temperature sensor 2 monitors that the outside temperature is higher than 30 degrees, the temperature difference between the inside and outside of the heat preservation cover is not much, and the heat preservation cover can be used directly for heat preservation, and the first heating plate 35 and the second heating plate 14 stop heating.

[0034] When the temperature changes for a long time, stress and gap are generated at the interface of the two flanges, resulting in water leakage, and when there are no workers around temporarily, the leaked water slides along the outer ring of the flange, eventually flows to the bottom of the flange and flows into the inside of the chute 661. The water flows diagonally downward along the chute 661 and flows into the inside of the water supply pipe 691. The water supply pipe 691 transports the leaked water to the inside of the water collecting tank 696 for storage. The leaked water continues to flow into the inside of the water collecting tank 696 until the gravity of the water collecting tank 696 and the internal water source is greater than the friction force between the gear 692 and the first and second gear plates 66 and 68. At this time, the water collecting tank 696 starts to move downward, thereby pulling the wire rope 694, and driving the I-shaped wheel 693 to rotate clockwise through the wire rope 694. When the I-wheel 693 rotates clockwise, it indirectly drives the gear 692 to rotate clockwise, thereby driving the first tooth plate 66 and the second tooth plate 68 to approach each other, and then driving the first curved rubber plate 61 and the second curved rubber plate 64 to approach the flange connection at the same time, until the first curved rubber plate 61 and the second curved rubber plate 64 cover the connection seam of the two flanges. At this time, the water source no longer drips and the water collecting tank 696 no longer slides downward until the staff arrives and finds the leak. The staff pours out the water source inside the water collecting tank 696, so that the first curved rubber plate 61 and the second curved rubber plate 64 return to their positions. The staff then repairs the leaking flange connection. The return anti-leakage mechanism 6 can be reused to prevent the water source from continuing to leak when the staff is not there.

[0035] By setting a temperature sensor 2 to monitor the ambient temperature outside the heat preservation cover in real time, the heating power of the first heating plate 35 and the second heating plate 14 can be controlled according to the ambient temperature outside, which can not only improve the heat preservation effect of the heat preservation cover at room temperature, but also perform high-power heating under extremely low temperature conditions around the heat preservation cover to prevent the fluid inside the plate heat exchanger 5 from freezing. In addition, when there are no staff around the plate heat exchanger 5 temporarily, the temperature changes for a long time, and stress and gap are generated at the two flange interfaces. When water leakage occurs, the inclined groove 661, the water collecting box 696, the wire rope 694, the I-shaped wheel 693, the gear 692, the first gear plate 66, the second gear plate ... Plate 68, the first curved rubber plate 61 and the second curved rubber plate 64 can not only collect the water leaking from the plate heat exchanger to prevent the water from dripping onto the surface of the protective cover and causing oxidation and rust, but also can pull the wire rope 694 through the gravity of the water flowing into the water collecting tank 696, driving the I-shaped pulley 693 and the gear 692 to rotate at the same time, so that the first curved rubber plate 61 and the second curved rubber plate 64 are respectively close to the connection between the two flanges, covering the connection seam of the two flanges, effectively preventing the plate heat exchanger 5 from leaking too much water, and taking anti-leakage protection measures before the staff rushes to repair it, reducing the impact of leakage on production activities and the insulation cover.
