Description

Technical Field

[0001] The present invention relates to the technical field of condensers, and particularly to an enamel circular flat three-hole plate condenser. Background Art

[0002] The enamel flat plate condenser is a highly efficient and corrosion-resistant heat exchange device. Its working principle is based on the heat exchange principle. High-temperature materials and cooling water are respectively introduced into two carefully designed misaligned clamping cavities inside the condenser. When they meet at different parts of the condenser, heat exchange occurs between them: the high-temperature material releases heat, and this heat is absorbed by the cooling water, thereby gradually reducing the temperature of the high-temperature material to the required condensation temperature.

[0003] To ensure the purity of the cooling water and improve the heat exchange efficiency, usually, filtration treatment is carried out before the cooling water enters the condenser to remove impurities such as suspended solids and particulate matters in the water, preventing them from depositing in the clamping cavity and affecting the heat exchange effect.

[0004] However, despite taking filtration measures, there are still various ions dissolved in the cooling water, such as calcium ions, magnesium ions, etc. As the temperature of the cooling water rises during the heat absorption process, the solubility of these ions changes, resulting in the precipitation of some ions from the water, forming so-called "scale" or "impurities". These precipitated impurities will gradually deposit in the clamping cavity. On the one hand, the deposited impurities will change the flow surface in the clamping cavity, making it no longer flat, thereby reducing the effective heat exchange area and leading to a decrease in the heat exchange efficiency. On the other hand, the deposition of impurities will also increase the flow resistance of the cooling water, causing an increase in the pressure loss of the condenser, and further affecting its overall performance and operating efficiency. Based on this, the present invention purposefully provides an enamel circular flat three-hole plate condenser that avoids the deposition of impurities precipitated from the cooling water in the clamping cavity during the heat exchange process. Summary of the Invention

[0005] The purpose of the present invention is to provide an enamel circular flat three-hole plate condenser for the deficiencies of the prior art to solve the technical problems in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] An enamel circular flat three-hole plate condenser, comprising:

[0008] Enamel condenser, in which a plurality of misaligned material flow channels and cooling water flow channels are arranged. A plurality of internal connecting pipes are arranged in each cooling water flow channel. The material flow channels at different heights are interconnected through the plurality of internal connecting pipes, and the cooling water flow channels at different heights are interconnected through a plurality of external connecting pipes. The top of the enamel condenser is communicated with a material inlet and is also communicated with a refrigerant outlet. The bottom of the enamel condenser is communicated with a material outlet and is also communicated with a refrigerant inlet. The material inlet is communicated with the material outlet through the material flow channel, and the refrigerant inlet is communicated with the refrigerant outlet through the cooling water flow channel;

[0009] Box body, which is arranged between an external connecting pipe and a cooling water flow channel. An input pipe and an output pipe are fixedly connected inside the box body. The input pipe is communicated with the outlet of an external connecting pipe, and its outlet is communicated with a three-way joint. Both outlets of the three-way joint are communicated with a filter cylinder. A filter screen is arranged in the filter cylinder. Each filter cylinder is communicated with the output pipe through a connecting pipe. The outlet of the output pipe is communicated with a cooling water flow channel, and the filter screen is located above the connection port between the three-way joint and the filter cylinder and below the connection port between the filter cylinder and the connecting pipe.

[0010] As a further solution of the present invention: a heat exchanger is fixedly installed inside the box body, and a circulating pipe is arranged inside it. The circulating pipe is arranged through the output pipe, its inlet is communicated with the output end of the heat exchanger, and its outlet is communicated with the input end of the heat exchanger.

[0011] As a further solution of the present invention: a control valve is arranged on the three-way joint. A valve rod is slidably connected inside the control valve. The valve rod is driven by a driving source arranged inside the control valve to move. One end of the valve rod extends into the three-way joint, and two symmetrically arranged conical blocks are fixedly connected to this end. The radius of the conical block near the three-way joint is smaller than the radius of its end far from the three-way joint, and the radius of the end of the conical block far from the three-way joint is larger than the radius of the outlet of the three-way joint. A butterfly valve is arranged on each connecting pipe. A valve flap is rotatably installed inside the butterfly valve. A linkage assembly is arranged on the control valve. When the driving source drives the valve rod to move, one conical block moves away from the three-way joint, and the other conical block blocks the three-way joint. At the same time, the movement of the valve rod drives one valve flap to rotate and open the connecting pipe through the linkage assembly, and the other valve flap blocks the connecting pipe.

[0012] As a further solution of the present invention: the filter screen is detachably installed, and the top cover of the filter cylinder is detachably installed.

[0013] As a further solution of the present invention: the linkage assembly includes a gear and a rack plate. The two gears are respectively rotatably installed on the two butterfly valves, and the gears are coaxially and fixedly connected to the rotating shafts of the valve flaps. The rack plate is slidably installed on the control valve and is fixedly connected to the valve rod located inside the control valve. The two gears are both meshed with the rack plate.

[0014] As a further solution of the present invention: a guiding groove is provided in the material flow channel, and two adjacent inner communication pipes are symmetrically arranged with respect to the guiding groove.

[0015] As a further solution of the present invention: a plurality of flow guiding plates are fixedly installed in the cooling water flow channel to form a cross-flow channel.

[0016] As a further solution of the present invention: a plurality of fixing rods are circumferentially arranged on the outer circumferential surface of the enamel condenser.

When the two clamping blocks approach each other, the enamel condenser is clamped by the two clamping blocks.

[0017] Advantages of the present invention:

[0018] 1. In the present invention, after continuous heat exchange between the cooling water and the high-temperature material, the cooling water will heat up and precipitate impurities in the water. Subsequently, the heated cooling water with impurities will enter the input pipe through the outer communication pipe, and then flow to the filter cylinder through the three-way joint. The filter net arranged in the middle of the filter cylinder can intercept the impurities precipitated in the cooling water, preventing the impurities from returning to the cooling water flow channel with the cooling water and continuing to circulate. This helps to maintain the cleanliness of the cooling water, avoid the accumulation of impurities in the heat exchange equipment, thereby reducing problems such as equipment scaling and corrosion, and extending the service life of the equipment;

[0019] 2. In the present invention, since the filtered cooling water needs to pass through the output pipe to return to the cooling water flow channel again, the circulation pipe is arranged to penetrate the output pipe. The low-temperature cooling water circulating in the circulation pipe can exchange heat with the heated cooling water, thereby reducing the temperature of the cooling water that is about to return to the cooling water flow channel again. On the one hand, it can reset the temperature of the cooling water and improve the heat exchange efficiency with the high-temperature material above. On the other hand, for the stabilized cooling water, it is not easy to precipitate impurities and other substances inside, avoiding the problem of sedimentation of impurities in the cooling water flow channel;

[0020] 3. In the present invention, the number of filter cylinders is set to two, so that the filter cylinders can be used alternately, and the filter net in the idle filter cylinder can be replaced and cleaned to ensure the filtering effect of the filter net and prevent impurities from entering the cooling water flow channel.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-9 As shown, the present invention is an enamel round flat three-hole plate condenser, including:

[0034] Enamel condenser 1, within which there are multiple misaligned material flow channels 8 and cooling water flow channels 9 arranged. In each cooling water flow channel 9, there are multiple internal connecting pipes 6. The multiple material flow channels 8 at different heights are interconnected through the multiple internal connecting pipes 6, and the multiple cooling water flow channels 9 at different heights are interconnected through multiple external connecting pipes 7. The top of the enamel condenser 1 is connected to the material inlet 2 and is also connected to the refrigerant outlet 5. The bottom of the enamel condenser 1 is connected to the material outlet 3 and is also connected to the refrigerant inlet 4. The material inlet 2 is connected to the material outlet 3 through the material flow channel 8, and the refrigerant inlet 4 is connected to the refrigerant outlet 5 through the cooling water flow channel 9;

[0035] Box body 10, which is arranged between an external connecting pipe 7 and the cooling water flow channel 9. Inside the box body 10, an input pipe 11 and an output pipe 16 are fixedly connected. The input pipe 11 is connected to the outlet of an external connecting pipe 7, and its outlet is connected to a tee 12. Both outlets of the tee 12 are connected to a filter cartridge 13. Inside the filter cartridge 13, there is a filter screen 14. Each filter cartridge 13 is connected to the output pipe 16 through an adapter pipe 15. The outlet of the output pipe 16 is connected to a cooling water flow channel 9, and the filter screen 14 is located above the connection port between the tee 12 and the filter cartridge 13, and the filter screen 14 is located below the connection port between the filter cartridge 13 and the adapter pipe 15.

[0036] In one case of this embodiment, the enamel type selected for the enamel condenser 1 is WH-I type and WH-II type. The main reason for selecting enamel is that enamel has good heat transfer effect, excellent corrosion resistance, and is easy to maintain and clean. When used as a condenser, the WH-I type and WH-II type have significant advantages such as corrosion resistance, easy cleaning, good thermal stability, efficient heat exchange, strong adaptability, energy conservation and environmental protection, and customization.

[0037] Working principle of the present invention: First, high-temperature materials are injected from the material inlet 2, and then enter the first-layer material flow channel 8. Subsequently, they enter the next-layer material flow channel 8 through the internal connecting pipe 6, and finally flow through all the material flow channels 8 from top to bottom and flow out from the material outlet 3. The cooling water is injected from the refrigerant inlet 4, first fills the lowermost cooling water flow channel 9, and then gradually fills the upper-layer cooling water flow channel 9 through the external connecting pipe 7. Finally, all the cooling water flow channels 9 are filled from bottom to top and discharged from the refrigerant outlet 5. The material flow channels 8 and the cooling water flow channels 9 are arranged in a staggered manner. Therefore, during the process of the high-temperature materials flowing in the material flow channels 8, heat exchange will occur with the cooling water flowing in the cooling water flow channels 9, thereby realizing the basic condensation process. As the heat exchange progresses, the temperature of the cooling water will rise. Specifically, the temperature of the cooling water flowing in the upper cooling water flow channel 9 is significantly higher than that of the cooling water in the lower cooling water flow channel 9. As the cooling water heats up, impurities in it will precipitate. At this time, the heated cooling water with impurities will enter the input pipe 11 through the external connecting pipe 7. Subsequently, the cooling water flows from the tee 12 into the filter cartridge 13 and gradually fills the filter cartridge 13. A filter screen 14 is arranged in the middle of the filter cartridge 13 to intercept the impurities precipitated in the cooling water, so that the clean cooling water flows into the output pipe 16 through the adapter pipe 15 and returns to the cooling water flow channel 9 through the output pipe 16, preventing the impurities from returning to the cooling water flow channel 9 with the cooling water and continuing to circulate. This helps to maintain the cleanliness of the cooling water, avoid the accumulation of impurities in the cooling water flow channel 9, and thus reduce problems such as scaling and corrosion.

[0038] As Figures 1-5 shown, as a preferred embodiment of the present invention, a heat exchanger 18 is fixedly installed in the box body 10, and a circulation pipe 17 is arranged inside it. The circulation pipe 17 is arranged through the output pipe 16, its inlet is communicated with the output end of the heat exchanger 18, and its outlet is communicated with the input end of the heat exchanger 18.

[0039] In one case of this embodiment, it should be noted that the heat exchanger 18 described in the present invention is a prior art, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0040] In actual application of this embodiment, since the filtered cooling water needs to pass through the output pipe 16 to return to the cooling water flow channel 9 again, the circulation pipe 17 is arranged through the output pipe 16. The low-temperature cooling water circulating in the circulation pipe 17 can exchange heat with the heated cooling water after heat exchange, thereby reducing the temperature of the cooling water that is about to return to the cooling water flow channel 9 again. On the one hand, it can reset the temperature of the cooling water and improve the heat exchange efficiency for the high-temperature materials above. On the other hand, after the temperature of the cooling water is stabilized, it is not easy for impurities and other substances to precipitate inside it, avoiding the problem of sedimentation of impurities in the cooling water flow channel 9.

[0041] As Figures 1-7 shown, as a preferred embodiment of the present invention, a control valve 21 is provided on the tee 12. A valve stem 20 is slidably connected within the control valve 21. The valve stem 20 is driven to move by a driving source built into the control valve 21. One end of the valve stem 20 extends into the tee 12, and two symmetrically arranged tapered blocks 19 are fixedly connected to this end. The radius of the tapered block 19 near one end of the tee 12 is smaller than the radius of its far end from the tee 12, and the radius of the far end of the tapered block 19 from the tee 12 is larger than the outlet radius of the tee 12. A butterfly valve 22 is provided on each adapter pipe 15. A valve flap 23 is rotatably installed within the butterfly valve 22. A linkage assembly is provided on the control valve 21. When the driving source drives the valve stem 20 to move, one tapered block 19 moves away from the tee 12, and the other tapered block 19 blocks the tee 12. At the same time, the movement of the valve stem 20 drives one valve flap 23 to rotate and open the adapter pipe 15 through the linkage assembly, and the other valve flap 23 blocks the adapter pipe 15.

[0042] In one case of this embodiment, the driving source can be selected from components such as an electric cylinder, a screw and slider assembly driven by a motor, and other mechanisms capable of realizing reciprocating motion. This embodiment does not specifically limit this here. A drain valve is provided in each filter cartridge 13.

[0043] In the actual application of this embodiment, as Figure 6 shown, for example, when the cooling water enters the tee 12 from the input pipe 11, at this time, the tapered block 19 opens the left filter cartridge 13, and the right filter cartridge 13 is closed by the tapered block 19. Therefore, the cooling water enters the left filter cartridge 13, and at this time, the left valve flap 23 is opened. At this time, the cooling water filtered by the filter net 14 will enter the output pipe 16 from the left adapter pipe 15 and finally return to the cooling water flow channel 9. When the filtering effect of the left filter net 14 decreases after long-term use, the driving source drives the valve stem 20 to move to the right. The tapered block 19 will block the left filter cartridge 13 and open the right filter cartridge 13. The rightward movement of the valve stem 20 will drive the left valve flap 23 to block the left adapter pipe 15 and open the right adapter pipe 15 through the linkage assembly. At this time, the cooling water will flow through the right filter cartridge 13 and be filtered by the new filter net 14, thus ensuring the filtering effect. And only one adapter pipe 15 is communicated with the output pipe 16, avoiding the cooling water flowing into the output pipe 16 from flowing back into the idle filter cartridge 13, and the cooling water in the idle filter cartridge 13 can be discharged through the drain valve.

[0044] As Figures 1-7 shown, as a preferred embodiment of the present invention, the filter net 14 is detachably installed, and the top cover of the filter cartridge 13 is detachably installed.

[0045] In actual application of this embodiment, by detachably installing both the filter screen 14 and the top cover of the filter cartridge 13, when a filter cartridge 13 is idle, the top cover of the filter cartridge 13 can be removed, and the filter screen 14 can be replaced or cleaned, ensuring the impurity interception and filtration effect of the filter screen 14, and this will not affect the normal operation of the entire condensation system.

[0046] As Figures 1-7 shown, as a preferred embodiment of the present invention, the linkage assembly includes a gear 24 and a rack plate 25. The two gears 24 are respectively rotatably installed on the two butterfly valves 22, and the gear 24 is coaxially and fixedly connected to the rotating shaft of the valve flap 23. The rack plate 25 is slidably installed on the control valve 21 and is fixedly connected to the valve rod 20 located inside the control valve 21. The two gears 24 are both engaged with the rack plate 25.

[0047] In actual application of this embodiment, when the drive source drives the valve rod 20 to move, the valve rod 20 will drive the rack plate 25 to translate. Since the rack plate 25 and the gear 24 are engaged, the translation of the rack plate 25 will drive the gear 24 to rotate, and the gear 24 will drive the valve flap 23 to rotate. In this way, one valve flap 23 will block the transfer pipe 15, and the other valve flap 23 will open the transfer pipe 15. In this way, only by using one power source of the drive source can the purpose of changing the cooling water flow channel be achieved.

[0048] As Figures 1-8 shown, as a preferred embodiment of the present invention, a guiding groove 801 is provided in the material flow channel 8, and the two adjacent inner communication pipes 6 are symmetrically arranged with respect to the guiding groove 801.

[0049] In actual application of this embodiment, when the high-temperature material flows from the first-layer material flow channel 8 to the second-layer material flow channel 8 through the inner communication pipe 6, the high-temperature material will, under the guidance of the guiding groove 801, flow into the inner communication pipe 6 of the second-layer material flow channel 8, and thus continue to flow downward into the third-layer material flow channel 8. In this way, it circulates back and forth, and finally the heat-exchanged and cooled material will be discharged through the material outlet 3. Among them, the guiding groove 801 plays a role in guiding the material in the material flow channel 8 to the outlet in an orderly manner, avoiding accumulation in the material flow channel 8.

[0050] As Figure 9 shown, as a preferred embodiment of the present invention, a plurality of guide plates 901 are fixedly installed in the cooling water flow channel 9 to form a cross-flow channel.

[0051] In actual application of this embodiment, when the cooling water flows in the cooling water flow channel 9, it is blocked and guided by the flow guide plate 901, so that the cooling water will cross-flow in each layer of the cooling water flow channel 9, and the residence time of the cooling water in each layer is longer, so that it can fully exchange heat with the high-temperature material in the material flow channel 8, improving the heat exchange efficiency.

[0052] As Figures 1-3 shown, as a preferred embodiment of the present invention, a plurality of fixing rods 26 are circumferentially arranged on the outer circumferential surface of the enamel condenser 1. A clamping block 27 is slidably installed at both the upper and lower ends of the fixing rod 26, and a nut 28 is threadedly connected to both ends of the fixing rod 26. When the two clamping blocks 27 approach each other, the two clamping blocks 27 clamp the enamel condenser 1.

[0053] In actual application of this embodiment, the overall height of the enamel condenser 1 can be changed by changing the number of layers of the material flow channel 8 and the cooling water flow channel 9. The clamping block 27 is slidably installed on the fixing rod 26. When the height of the enamel condenser 1 changes, the clamping block 27 can slide on the fixing rod 26, so that the clamping block 27 always abuts against the enamel condenser 1. Then, the nut 28 is tightened, so that the upper and lower clamping blocks 27 clamp the enamel condenser 1, so that the height of the enamel condenser 1 can be adjusted according to production requirements.

[0054] A detailed description of an embodiment of the present invention has been given above, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
