Description

Technical Field

[0001] The present invention relates to the technical field of rotary jet pumps, and more particularly to a rotary jet pump for conveying high-temperature materials. Background Art

[0002] Rotary jet pumps are widely used in the transportation of high temperature, high viscosity or high heat load materials, such as stainless steel pipe polishing liquid, hot cleaning agent, industrial slurry and other fields;

[0003] However, existing rotary pump bodies generally have problems with insufficient structural adaptability, such as:

[0004] During the use of existing devices, the internal structure of the pump body will undergo significant thermal expansion and contraction deformation due to the influence of high temperature during continuous operation, causing the seal to move or even the structure to expand and become stuck, affecting the stable operation of the device;

[0005] Especially in the structure involving the feeding wheel to transmit materials, the surface teeth are very likely to experience dimensional expansion, material cracking, uneven wear and other problems under the impact of high temperature. In severe cases, it will lead to uneven feeding and even failure of the injection system.

[0006] In addition, in the existing structure, during the feeding process, vortex areas are easily formed on both sides of the teeth due to fluid disturbance, which can easily cause problems such as material backflow, particle retention, and tooth groove jamming, thereby reducing material conveying efficiency.

[0007] Therefore, we designed a rotary jet pump for conveying high-temperature materials. Summary of the Invention

The positioning rotating wheel shaft is used to rotate the feeding wheel and fix the feeding wheel. A chamber partition is installed inside the feeding chamber, and the chamber partition is used to isolate the internal space of the feeding chamber.

[0012] The cam is secured to the lip of the lock member and is secured to a position that the cam has a central position within the lock member and is adapted to engage said locking member when the lock member is unlocked.

[0013] Furthermore, the sealing compensator is made of a soft material, such as fluororubber, polytetrafluoroethylene or modified silicone. The sealing compensator is used to provide elastic deformation of the feeding chamber and the chamber partition during thermal expansion and contraction, so as to compensate for the structural displacement of the chamber partition and absorb contact stress.

[0014] When the soft material is made of fluororubber, the surface of the sealing compensator is coated with a mixed coating of FEP and molybdenum disulfide;

[0015] When the soft material is constructed of polytetrafluoroethylene, the surface of the sealing compensator is coated with a mixed coating of perfluoroalkoxy and micro-ceramic particles;

DETAILED DESCRIPTION

[0037] 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. Example

[0038] See also Figure 1-9 The present invention provides a technical solution: a rotary jet pump for conveying high-temperature materials, comprising:

[0039] A pump body 1, the interior of the pump body 1 is provided with a combined screw hole 2, the pump body 1 is a split-type plug-in, the combined screw hole 2 is used to fix the installation of the pump body 1, the interior of the pump body 1 is provided with a pump filling block 3, the pump filling block 3 is a split-type design installation, the interior of the pump body 1 is provided with a feed pipe 4, and the interior of the pump body 1 is provided with a discharge pipe 5;

[0040] The feeding chamber 6 is provided inside the filling block 3 in the pump machine. A feeding wheel 7 is installed inside the feeding chamber 6. The feeding chamber 6 is connected to the discharge pipe 5 and the feed pipe 4. The feed pipe 4 and the discharge pipe 5 also pass through the filling block 3 in the pump machine. The periphery of the feeding wheel 7 abuts against the inner wall of the feeding chamber 6.

[0041] In this embodiment: It should be noted that, during the use of the product pump body 1, the two pump bodies 1 are merged by merging the screw holes 2. During the merging process of the two pump bodies 1, the feeding chamber 6 becomes an independent cavity. At this time, the feeding chamber 6 is closed for use, and one end of the feed pipe 4 is connected to the feed liquid. During the rotation of the feeding wheel 7, the interior of the feeding chamber 6 can be isolated into multiple chambers. At this time, the chamber of the feeding chamber 6 close to the feed pipe 4 is the feeding chamber, and the feeding chamber 6 close to the outlet is the feeding chamber. The chamber on one side of the material pipe 5 is the discharge chamber. During specific use, the feeding wheel 7 rotates, and the material liquid passes through the gap between each tooth on the surface of the feeding wheel 7 and the inner wall of the feeding chamber 6, and the material liquid is transported to the chamber close to the discharge pipe 5. Among them, the rotation speed of the feeding wheel 7 determines the amount of material liquid transported. Therefore, by controlling the rotation speed of the feeding wheel 7, the feeding rate of the feed pipe 4 can be controlled. This is the basic operating principle of the pump body 1. Next, we will gradually introduce the various functions of the pump body 1.

[0042] like Figure 1-9 As shown, both ends of the feeding wheel 7 are fixedly plugged with a positioning rotating wheel shaft 8, the positioning rotating wheel shaft 8 is used to rotate the feeding wheel 7 and fix the feeding wheel 7, the interior of the feeding chamber 6 is installed with a chamber partition 9, the chamber partition 9 is used to isolate the internal space of the feeding chamber 6, the positioning rotating wheel shaft 8 on one side of the feeding wheel 7 passes through the chamber partition 9 and is connected to an external transmission wheel 12, one side of the external transmission wheel 12 is connected to an output shaft 32, the positioning rotating wheel shaft 8 on the side of the feeding wheel 7 away from the external transmission wheel 12 is inserted in the inner wall of the feeding chamber 6, for fixing the rotation of the feeding wheel 7, the interior of the chamber partition 9 is installed with an embedded retaining ring 10.

[0043] In this embodiment: When the device is in use, the specific working principle of the feeding wheel 7 is that the output shaft 32 is driven to rotate an external transmission wheel 12, and the positioning rotating wheel shaft 8 is driven to rotate at a uniform speed during the rotation of the embedded clamp ring 10. The rotation of the embedded clamp ring 10 will drive the feeding wheel 7 to rotate with it through the positioning rotating wheel shaft 8, and then the feeding wheel 7 can pump the material liquid inside the feeding pipe 4 under the air pressure difference in the closed feeding chamber 6, so that the internal material liquid of the feeding pipe 4 is transported to the discharge pipe 5 through the surface of the feeding wheel 7 under the cooperation limit of the feeding chamber 6 and is output.

[0044] like Figure 1-9 As shown, a sealing compensator 13 is installed at the connection between the chamber partition 9 and the inner wall of the feeding chamber 6, and a supporting positioning column 15 is connected to the end of the sealing compensator 13 close to the chamber partition 9, and a supporting chimeric column 14 is installed on the side of the supporting positioning column 15 away from the sealing compensator 13. An expansion sealing ring 11 is installed on the surface of the chamber partition 9, and the supporting chimeric column 14 is fixedly connected to the surface of the expansion sealing ring 11. A second sealing limit plate 16 is installed on the side of the chamber partition 9 close to the embedded clamping ring 10, and the embedded clamping ring A first sealing limit plate 17 is installed on the side of 10 close to the chamber partition 9, a second sealing compensation block 18 is provided between the overlap of the sleeve clamp ring 10 and the chamber partition 9, a chimeric sealing card plate 19 is overlapped on the surface of the chamber partition 9, and the chimeric sealing card plate 19 is used to clamp the connection between the sleeve clamp ring 10 and the chamber partition 9, a connecting chimeric shaft 20 is installed inside the sleeve clamp ring 10, and a sealing shaft ring 21 is chimerically connected to the surface of the connecting chimeric shaft 20, and the positioning rotating wheel shaft 8 passes through the inside of the connecting chimeric shaft 20;

[0045] In this embodiment, we now solve the sealing problem of the penetration of the positioning rotating wheel shaft 8 and the chamber partition 9. As mentioned above, the arrangement of the chamber partition 9 is used to divide the interior of the feeding chamber 6 with the chamber partition 9 as the dividing line, and form two cavities in the installation area of ​​the embedded clamping ring 10 and the installation area of ​​the feeding wheel 7, thereby effectively ensuring that the rotation of the embedded clamping ring 10 will not affect the sealing use inside the feeding chamber 6. In this way, the chamber partition 9 can effectively ensure the sealing of the cavity on the side of the feeding wheel 7 during use, which is the top priority in the design. It can be seen that by arranging the embedded clamping ring 10 in an I-shape and installing it at the penetration connection between the chamber partition 9 and the positioning rotating wheel shaft 8, the sealing of the chamber partition 9 and the positioning rotating wheel shaft 8 during use is ensured. By setting the second sealing compensation block 18, when the recesses of the chamber partition 9 and the embedded clamping ring 10 are in contact, the second sealing compensation block 18 is used for filling efficiency to fill the chamber. During the sealing process of the partition 9 and the embedded clamp ring 10, all gaps between the embedded sealing card plate 19 and the chamber partition 9 are completely filled. During the filling process, the embedded sealing card plate 19 will be squeezed due to the presence of the first sealing limit plate 17 and the second sealing limit plate 16. At the same time, during the squeezing process, the second sealing compensation block 18 extends to any place where there is a gap until it is completely sealed. According to the temperature of the liquid exposed to the internal cavity of the feeding chamber 6, the chamber partition 9 and its related structures near the feeding chamber 6 side are likely to have the problem of thermal expansion and contraction. Under the condition of thermal expansion, the embedded sealing card plate 19 will also expand and begin to expand the contact surface between itself and the chamber partition 9. Of course, there may also be the problem of warping. Therefore, through the provision of the second sealing compensation block 18, in this case, the connection between the embedded sealing card plate 19 and the chamber partition 9 can be effectively filled to ensure that the feeding chamber 6 can continue to operate in a closed chamber environment;

[0046] Due to the consideration of thermal expansion, we have also made some changes to the structural parts of the chamber partition 9. It can be seen that the chamber partition 9 has now become a multi-layer support structure. The main body of the chamber partition 9 is still made of rigid materials. However, considering the thermal barrier properties of metal, it will definitely not be able to fit the inner cavity of the feeding chamber 6 made of metal when the temperature difference changes greatly. Therefore, we set an expansion sealing ring 11 and open a concentric annular groove on the surface of the chamber partition 9 to reduce the body deformation of the chamber partition 9. At the same time, the terminal deformation of the chamber partition 9 is reduced by setting the expansion sealing ring 11, and a supporting interlocking column 14 is installed on the chamber partition 9, so that one end of the supporting interlocking column 14 can effectively support the sealing compensation part 13 of the outer ring of the chamber partition 9 through the supporting positioning column 15. Figure 3The chamber partition 9 is a front view. It should be noted that the thickness of the sealing compensator 13 is greater than the thickness of the chamber partition 9, so that the supporting chimeric column 14 supports the sealing compensator 13 and the inner wall of the feeding chamber 6 through the supporting positioning column 15. In the process of the supporting positioning column 15 abutting the sealing compensator 13, the supporting chimeric column 14 itself is also supported in the reverse direction by the force of the supporting positioning column 15. Therefore, the supporting positioning column 15 drives the supporting chimeric column 14 to also play a reverse positioning effect, thereby ensuring that the expansion sealing ring 11 can be engaged with the surface of the chamber partition 9 and will not fall off, thereby strengthening the sealing effect of the chamber partition 9;

[0047] Regarding the connection problem between the supporting interlocking column 14 and the supporting positioning column 15, we would like to add an explanation. The sealing compensator 13 is a filling piece between the chamber partition 9 and the feeding chamber 6, which is used to compensate for the gap at the connection between the chamber partition 9 and the feeding chamber 6. During the thermal expansion of the sealing compensator 13, the expansion sealing ring 11 will also begin to expand. The supporting interlocking column 14 is connected to the side of the expansion sealing ring 11 near the feeding chamber 6 at the axis. During the simultaneous expansion of the expansion sealing ring 11 and the sealing compensator 13, the supporting interlocking column 14 serves as a support member between the expansion sealing ring 11 and the sealing compensator 13. It can penetrate the expansion sealing ring 11 and the close supporting positioning column 15, and at the same time, it can also support the sealing compensator 13 through the supporting positioning column 15 to expand the expansion support of the sealing compensator 13. During the expansion of the sealing compensator 13, the volume of the sealing compensator 13 will exceed the chamber partition 9 and the feeding chamber. The contact surface of chamber 6, if the sealing compensator 13 is not limited, the sealing compensator 13 may curl after exceeding the support limit of the filling block 3 in the pump machine. If this problem is allowed to occur, after long-term use, after continuous thermal expansion and contraction, the curled part of the sealing compensator 13 cannot shrink and reset. Therefore, in order to enhance the service life of the sealing compensator 13 and to ensure the sealing effect of the chamber partition 9 and the feeding chamber 6, we expand the edge contact surface of the sealing compensator 13 by supporting the positioning column 15, and as the expansion sealing ring 11 and the sealing compensator 13 expand together, the expansion sealing ring 11 is set with a soft material, and in the process of expansion and support of the sealing compensator 13, the sealing compensator 13 can drive the support positioning column 15, so that the angle of the support positioning column 15 can be fine-tuned, thereby ensuring the support effect of the support positioning column 15 and the support interlocking column 14 on the sealing compensator 13.

[0048] like Figure 1-9 As shown, the sealing compensator 13 is made of a soft material such as fluororubber, polytetrafluoroethylene or modified silicone. The sealing compensator 13 is used to provide elastic deformation of the feeding chamber 6 and the chamber partition 9 during thermal expansion and contraction, thereby compensating for the structural displacement of the chamber partition 9 and absorbing contact stress.

[0049] When the soft material is constructed of fluororubber, the surface of the sealing compensator 13 is coated with a mixed coating of FEP and molybdenum disulfide;

[0050] When the soft material is constructed of polytetrafluoroethylene, the surface of the sealing compensator 13 is coated with a mixed coating of perfluoroalkoxy and micro-ceramic particles;

[0051] When the soft material is constructed of modified silicone material, the surface of the sealing compensator 13 is coated with an organic silicon high temperature resistant coating and mixed with plasma fluorination surface treatment or fluorine-silicon copolymer coating;

[0052] The second sealing compensation block 18 is made of graphite-filled polytetrafluoroethylene material. The surface of the second sealing compensation block 18 is provided with a composite functional coating. The outer layer of the composite functional coating is a dry film lubricating layer composed of molybdenum sulfide, and the inner layer of the composite functional coating is a dense chemically stable layer formed by a perfluoroalkoxy polymer.

[0053] The chimeric sealing card plate 19 is a three-layer material structure, the inner layer material is a spring steel core structure, the middle layer material is a fluororubber structure, and the outer layer material is a FEP coating setting;

[0054] In this embodiment, we decided to use FEP as the specific coating material for the outer layer of the chimeric sealing card plate 19. According to the specific experimental results, although FEP coating has been used in many fields as an anti-stick coating of rubber materials, we set the chimeric sealing card plate 19 to a three-layer clamping structure of a spring steel core, a fluororubber elastomer and an FEP surface layer, so as to give the chimeric sealing card plate 19 flexible release and adjustment capabilities during the dynamic clamping process. In particular, when there is a need for thermal deformation and compression coordination between the structural member, the embedded clamping ring 10 and the chamber partition 9, the FEP coating can maintain a constant clamping force while avoiding aging of the clamping material or cold adhesion to the metal surface. Therefore, the chimeric sealing card plate 19 is set in this way to meet our needs.

[0055] In addition, the second sealing compensation block 18 is provided primarily to fill the gap between the sleeve retaining ring 10 and the chamber partition 9, absorb axial thermal deformation, and provide dynamic sealing pressure compensation. Due to the aforementioned material configuration, when the pump body is operating at high speed, the second sealing compensation block 18 can deform slightly with temperature changes, always maintaining close contact with the sleeve retaining ring 10 and other structural components, thereby ensuring that the system's sealing is not affected by thermal changes.

[0056] The surface coating of the sealing compensator 13 is used to improve its surface stability and service life in a high-temperature rotating environment. It should be noted that the surface of the fluororubber body is preferably coated with an FEP coating to improve its surface inertness, anti-sticking and anti-coking properties under high-temperature working conditions. At the same time, a molybdenum disulfide lubricating film layer is coated to reduce its friction resistance and stress accumulation during structural deformation. It is mainly suitable for clamping connections and gap sealing interfaces.

[0057] When PTFE is selected as the material for the main body of the sealing compensator 13, a composite PFA coating may be selected on its surface to improve its wear resistance and micropore sealing performance. At the same time, a micro-ceramic particle reinforcement layer, including but not limited to aluminum oxide and zirconium oxide particles, may be combined to increase its surface hardness and crack resistance, thereby preventing crack propagation or powdering and shedding caused by long-term thermal loading.

[0058] When modified silicone is selected as the material for the main body of the sealing compensator 13, a high-temperature resistant silicone coating is preferably applied to its surface to improve its thermal aging stability. At the same time, plasma fluorination surface treatment or fluorine-silicon copolymer coating is used to further enhance its chemical inertness and anti-adsorption performance in high-temperature media.

[0059] Through the above-mentioned coating design, the sealing compensation part 13 can not only maintain the deformation and compensation ability of its core elastic structure, but also provide stable sealing performance and adaptive fit during contact with other related structures. It is especially suitable for use under complex working conditions such as high-frequency vibration, high-temperature load, and dynamic sealing.

[0060] like Figure 1-9 As shown, the surface of the feed pipe 4 is sheathed with a heat exchange ring 22, which is a double-layer structure. An exchange ring connecting valve 23 is installed between the two layers of heat exchange rings 22. The exchange ring connecting valve 23 passes through the surface of the feed pipe 4. A temperature control heating wire 26 is provided inside the heat exchange ring 22. The surface of the heat exchange ring 22 is connected to an inlet and outlet pipe 25, and one end of the inlet and outlet pipe 25 is connected to a pumping circulation pipe 24.

[0061] In this embodiment, through such a setting, during the use of the device, the feed pipe 4 can effectively control the material liquid inside the feed pipe 4 through the setting of the heat exchange ring 22 during the use, so as to achieve constant temperature or temperature reduction and heating and the like. It should be noted that the temperature control heating wire 26 itself is wound with structures such as resistance wire, and the temperature control heating wire 26 is divided into two groups, one group is wound in the heat exchange ring 22 outside the feed pipe 4, and the other group is wound in the heat exchange ring 22 inside the feed pipe 4. During the winding process, the canine-shaped structure of the temperature control heating wire 26 can effectively expand the contact area between it and the heat exchange ring 22 and the material liquid inside the feed pipe 4, thereby quickly completing the effect of heating the material liquid passing through the feed pipe 4. However, during the use of the above-mentioned device, it should be noted that in order to ensure sufficient contact between the heat exchange ring 22 and the inside of the feed pipe 4, the bottom shell of the feed pipe 4 needs to be disassembled, and the heat exchange ring 22 is close to the bottom shell of the feed pipe 4. A removable sealed bottom shell 27 is provided on one side near the feed pipe 4, and a positioning slot 28 is fixedly connected to the inside of the heat exchange coil 22. The positioning slot 28 is used to support the pull-out connection of the removable sealed bottom shell 27, and a soft elastic material is provided at the connection between the positioning slot 28 and the removable sealed bottom shell 27. Through such a setting, it is ensured that the removable sealed bottom shell 27 can be used for disassembly so that the temperature control heating wire 26 can directly contact the internal liquid of the feed pipe 4. In addition, when it is necessary to cool the internal liquid of the feed pipe 4, the pumping circulation pipe 24 can be started at this time, and the liquid can be circulated to the heat exchange coil 22 through the inlet and outlet pipes 25. The exchange coil connecting valve 23 is opened to make the two inner and outer heat exchange coils 22 in a connected state. At this time, under the setting of the temperature control heating wire 26, it will expand the contact surface between the internal circulating coolant and the inlet and outlet pipes 25, so that the inlet and outlet pipes 25 can quickly cool the liquid, thereby effectively ensuring the cooling effect of the device.

[0062] like Figure 1-9 As shown, a feed blade 29 is installed on the surface of the feed wheel 7, a compensation support 31 is provided inside the feed blade 29, and a guide auxiliary ring 30 is provided on both sides of the feed blade 29. The guide auxiliary ring 30 is made of soft material;

[0063] In this embodiment, if the rotation direction is set, Figure 8The partial display in the figure shows that the flow guide auxiliary rings 30 are arranged from small to large and are installed on the surface of the feed wheel 7. It should be noted that the largest flow guide auxiliary ring 30 must be installed on the side of the forward direction of the feed blade 29, that is, the side that finally meets the material. The flow guide auxiliary ring 30 is made of soft material and is used to seal and compensate for the feed blade 29 in the case of thermal expansion and contraction. At the same time, the setting of the flow guide auxiliary ring 30 also prevents the feed liquid from easily forming vortices in the feed blade 29 during the rotation of the feed wheel 7 and then colliding with the feed blade 29 behind. In this way, the service life of the feed blade 29 is enhanced through such a setting. In addition, it also has a flexible flow-through edge function, which can avoid the occurrence of dead-angle vortexes and other related problems. The compensation support 31 is made of corrugated flexible material and is nested in the inside of the feed blade 29 as a support when the feed blade 29 is thermally blocked and contracted. It can also avoid the feed blade 29 from easily causing stress deformation and other problems, thereby indirectly ensuring the service life of the feed blade 29.
