Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure water recovery, in particular to a high-pressure water recovery device which can be quickly disassembled and assembled. Background Art

[0002] With the continuous improvement of the domestic steel and chemical production technology level, high-pressure water systems are applied to steel, chemical, shipbuilding and other fields, such as high-pressure water descaling in the steel production process and high-pressure water coke cutting in the chemical production process. As the production process continues to increase the demand for high-pressure water pressure. In order to achieve energy conservation and emission reduction, it is necessary to discharge and recycle the high-pressure fluid generated by the system in the non-production state through a high-pressure water recovery device. As a major component of the high-pressure water recovery device, the throttling device can adjust the pressure and flow of the high-pressure fluid by changing the cross-sectional area or flow path of the high-pressure fluid, so that the high-pressure fluid reaches a pressure level suitable for recovery.

[0003] Existing high pressure water recovery devices such as Figure 1a and 1b As shown, it includes a throttling device 1' and a recovery pipe 2', wherein the throttling device 1' includes a throttling cylinder 11' and a core 12' arranged in the throttling cylinder 11' for throttling and reducing pressure, wherein the core 12' is composed of a plurality of sleeves 13' and an orifice plate 15' provided with a throttling hole 14', wherein the orifice plate 15' and the sleeve 13' are respectively provided with corresponding keyways and keyholes, and the connection between the orifice plate 15' and the sleeve 13' is achieved by respectively embedding a flat key 16' in the keyway and the keyhole, and at the same time, a flange 17' at the end of the throttling cylinder 11' is welded to the recovery pipe 2'. Thus, the high-pressure fluid enters the core 12' in the throttling cylinder 11', flows through the several sleeves 13' of the core 12' and flows out through the throttling hole 14' of the orifice plate 15', so that when the high-pressure fluid flows in the core 12', the pressure of the high-pressure fluid is reduced due to the local resistance of the orifice plate 15', and at the same time, under the action of the throttling hole 14', the flow beam shrinks and becomes thinner, reducing the flow rate, thereby achieving throttling and pressure reduction.

[0004] Since the throttling device in the high-pressure water recovery device is in a working environment impacted by high-pressure fluid, the core is easily damaged by the impact force of the high-pressure fluid. Therefore, the throttling cylinder and the core need to be maintained and replaced.

[0005] However, in the existing high-pressure water recovery device, the flange 17' at the end of the throttling cylinder 11' is welded to the recovery pipe 2'. When disassembling the throttling cylinder 11', the recovery pipe 2' needs to be cut off, which makes disassembly inconvenient and has a high cost. At the same time, the core 12' is directly fixedly connected to the cylinder wall of the throttling cylinder 11', resulting in that the core 12' cannot be disassembled separately for maintenance and replacement. Furthermore, the sleeve 13' and the orifice plate 15' in the core 12' are connected and matched by the flat key 16', which not only makes assembly and disassembly complicated, but also there is a gap between the flat key 16' and the throttling cylinder 11' due to the thickness of the flat key, which easily leads to leakage of high-pressure fluid in the core, affecting the stable operation of the throttling device.

[0006] Therefore, there is an urgent need in the art for a high-pressure water recovery device with a simple structure that can be quickly disassembled and installed to facilitate replacement and maintenance of the throttling device, thereby ensuring stable and reliable operation of the high-pressure water recovery system.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0040] See also Figure 2 , which shows an example of a quick-disassembly and assembly high-pressure water recovery device provided by the utility model.

[0041] As can be seen from the figure, the quick-detachable high-pressure water recovery device in this example mainly includes a throttling device 1 and a recovery pipeline 2.

[0042] Both ends of the throttling device 1 are connected to the recovery pipeline 2, wherein the inlet 11 of the throttling device 1 is connected to the inlet pipeline 21 of the recovery pipeline 2, and the outlet 12 is connected to the outlet pipeline 22 of the recovery pipeline 2; the throttling device 1 is configured to be composed of a plurality of throttling and pressure reducing sections 3, so that the high-pressure fluid can enter the throttling device 1 from the inlet pipeline 21, and the throttling and pressure reducing section 3 of the throttling device 1 is configured to reduce the flow rate of the high-pressure fluid and reduce the pressure of the high-pressure fluid, so that the high-pressure fluid enters the outlet pipeline 22 through the outlet 12 in a low-pressure state.

[0043] Specifically, see Figure 3 The throttling device 1 includes a throttling cylinder 13 and a core 14 arranged in the throttling cylinder 13. The throttling cylinder 13 is configured as a hollow cylinder. The core 14 is adapted to the inner diameter of the throttling cylinder 13 so that the core 14 can fit tightly on the inner wall of the throttling cylinder 13.

[0044] In order to connect and cooperate the throttling cylinder 13 and the core 14 and facilitate disassembly and assembly, the throttling cylinder 13 and the core 14 are detachably connected by a pressing sleeve 15, the core 14 is arranged in the middle of the throttling cylinder 13, and the pressing sleeve 15 is arranged at both ends of the throttling cylinder 13, one end of the pressing sleeve 15 is connected to the end of the throttling cylinder 13, and the other end is connected to the end of the core 14, the two ends of the core 14 are abutted and pressed against the two ends of the throttling cylinder 13, so that the core 14 does not offset or slide in the throttling cylinder 13, thereby fixing the core 14 in the throttling cylinder 13, and when disassembling, only the pressing sleeve 15 needs to be removed to take the core 14 out of the throttling cylinder 13, so as to facilitate the maintenance and replacement of the core 14 and the throttling cylinder 13.

[0045] Further, see Figure 4 A plurality of sleeves 16 and orifice plates 17 are provided in the core body 14, and the sleeves 16 and orifice plates 17 cooperate to form a plurality of throttling and pressure reducing sections 3, so that when the high-pressure fluid flows in the core body 14, the sleeves 16 and orifice plates 17 can cooperate to reduce the pressure and flow of the high-pressure fluid.

[0046] Among them, the sleeve 16 is configured as a cylinder with a hollow interior, and the orifice plate 17 is adapted to the cross-section of the sleeve 16 so that the orifice plate 17 can be connected to the end of the sleeve 16. Furthermore, a buckle 161 is provided on the sleeve 16, and a slot 171 adapted to the buckle 161 is provided on the orifice plate 17, so that the sleeve 16 and the orifice plate 17 are connected by inserting the buckle 161 into the slot 171, thereby forming a throttling and pressure reduction section 3. When disassembling, the sleeve 16 and the orifice plate 17 can be separated by simply pulling the buckle 161 out of the slot 171.

[0047] Compared with the prior art solution of using a flat key to connect the sleeve 16, the orifice plate 17 and the throttling cylinder 13, the connection and cooperation between the buckle 161 on the sleeve 16 and the notch 171 on the orifice plate 17 is adopted, which makes the disassembly and assembly quick, and there is no gap between the core body 14 and the throttling cylinder 13 caused by the use of a flat key, which is not easy to cause leakage of high-pressure fluid.

[0048] At the same time, a throttling hole 172 is also provided in the middle of the orifice plate 17 to allow the high-pressure fluid to enter the core 14. When it flows through the sleeve 16 and the orifice plate 17, the pressure of the high-pressure fluid is reduced due to the local resistance of the wall of the orifice plate 17. At the same time, the high-pressure fluid passes through the tiny throttling hole 172 to shrink the flow beam and reduce the flow rate, thereby achieving throttling and pressure reduction.

[0049] Furthermore, a plurality of throttling and pressure reducing sections 3 are provided in the core body 14 to improve the throttling and pressure reducing effect on the high-pressure fluid, wherein the sleeve 16 of the core body 14 includes a first-stage sleeve 311, a last-stage sleeve 331 and at least one intermediate-stage sleeve 321 arranged between the first-stage sleeve 311 and the last-stage sleeve 331, and the orifice plate 17 of the core body 14 includes a first-stage orifice plate 312, a last-stage orifice plate 332 and at least two intermediate-stage orifice plates arranged between the first-stage orifice plate 312 and the last-stage orifice plate 332, constituting a first-stage throttling and pressure reducing section 31, a last-stage throttling and pressure reducing section 33 and at least one intermediate-stage throttling and pressure reducing section 32 arranged between the first-stage throttling and pressure reducing section 31 and the last-stage throttling and pressure reducing section 33.

[0050] For details, see Figure 5 and Figure 6 The first-stage orifice plate 312 is arranged at the end of the first-stage sleeve 311, and the first-stage buckle 313 arranged at the end of the first-stage sleeve 311 is inserted into the slot 171 arranged on the first-stage orifice plate 312, thereby forming the first-stage throttling and pressure reduction section 31.

[0051] Furthermore, the first intermediate-stage orifice plate 322 and the second intermediate-stage orifice plate 323 are respectively arranged at the two ends of the intermediate-stage sleeve 321, and one end of the intermediate-stage sleeve 321 is provided with an intermediate-stage buckle 324 that is adapted to the notch on the first intermediate-stage orifice plate 322 and the first-stage notch 314 arranged at the other end of the first-stage sleeve 311, thereby the intermediate-stage buckle 324 is inserted into the notch on the first intermediate-stage orifice plate 322 and the first-stage notch 314 of the first-stage sleeve 311 at the same time, thereby connecting the intermediate-stage sleeve 321 and the first intermediate-stage orifice plate 322 to the first-stage throttling and pressure reduction section 31.

[0052] Furthermore, the final stage orifice plate 332 is arranged at the end of the final stage sleeve 331 , and the first final stage buckle 333 arranged at the end of the final stage sleeve 331 is inserted into the notch arranged on the final stage orifice plate 332 , thereby forming the final stage throttling and pressure reduction section 33 .

[0053] Furthermore, the other end of the final-stage sleeve 331 is provided with a second final-stage buckle 334 which is adapted to the notch on the second intermediate-stage orifice plate 323 and the intermediate-stage notch 325 arranged at the other end of the intermediate-stage sleeve 321, thereby the second final-stage buckle 334 is inserted into the notch on the second intermediate-stage orifice plate 323 and the intermediate-stage notch 325 of the intermediate-stage sleeve 321 at the same time, thereby connecting the intermediate-stage sleeve 321 and the second intermediate-stage orifice plate 323 with the final-stage throttling and pressure-reducing section 33.

[0054] As a result, the first-stage throttling and pressure-reducing section 31, the last-stage throttling and pressure-reducing section 33 and the intermediate-stage throttling and pressure-reducing section 32 are connected to each other through the bayonet and the slot to form the throttling and pressure-reducing section 3, which is easy to install. At the same time, when disassembling, it is only necessary to pull out the buckles on the first-stage throttling and pressure-reducing section 31, the last-stage throttling and pressure-reducing section 33 and the intermediate-stage throttling and pressure-reducing section 32 from the slot in turn, so that the throttling and pressure-reducing section 3 can be split into a plurality of sleeves 16 and orifice plates 17, so that the core body 14 can be quickly installed and disassembled.

[0055] Furthermore, there is no limitation on the position and number of the throttling holes 172 on the first-stage orifice plate 312, the last-stage orifice plate 332, the first intermediate-stage orifice plate 322 and the second intermediate-stage orifice plate 323. Preferably, a throttling hole 172 is provided on each of the first-stage orifice plate 312 and the last-stage orifice plate 332, and is respectively arranged in the middle of the first-stage orifice plate 312 and the last-stage orifice plate 332. Two throttling holes 172 are provided on each of the first intermediate-stage orifice plate 322 and the second intermediate-stage orifice plate 323, and are respectively distributed at different positions on the first intermediate-stage orifice plate 322 and the second intermediate-stage orifice plate 323. As an example, in this example, the two throttling holes 172 on the first intermediate-stage orifice plate 322 are vertically distributed, and the two throttling holes 172 on the second intermediate-stage orifice plate 323 are horizontally distributed, so that the high-pressure fluid is blocked by the orifice plate in the core 14 and needs to pass through the throttling holes 172 in different directions and numbers, thereby effectively reducing the pressure and flow rate during the flow process.

[0056] Thus, the high-pressure fluid enters the throttling cylinder 13 from the inlet pipe 21 of the recovery pipe 2 through the inlet 11 of the throttling device 1, flows in the core 14, passes through a plurality of throttling and pressure-reducing sections 3 in the core 14, enters the first-stage throttling and pressure-reducing section 31 from the throttling hole on the first-stage orifice plate 312, and then enters the intermediate-stage throttling and pressure-reducing section 32 through the two throttling holes vertically distributed on the first intermediate-stage orifice plate 322, and then enters the final-stage throttling and pressure-reducing section 33 through the two throttling holes horizontally distributed on the second intermediate-stage orifice plate 323, and finally enters the outlet pipe 22 from the outlet 12 of the throttling device 1 through the throttling hole on the final-stage orifice plate 332, thereby throttling and reducing the pressure of the high-pressure fluid so that it enters the outlet pipe 22 in a low-pressure state suitable for recovery.

[0057] Since the throttling device 1 is in a working environment impacted by high-pressure fluid, the core 14 is easily damaged by the impact force of the high-pressure fluid. Therefore, the throttling cylinder 13 and the core 14 need to be maintained and replaced.

[0058] Therefore, in order to enable the throttling device 1 to be quickly connected and disassembled with the recovery pipe 2 so as to maintain and replace the throttling device 1, the throttling device 1 is detachably connected to the inlet pipe 21 and the outlet pipe 22 through the throttling flanges 18 arranged at both ends of the throttling cylinder 13, taking the connection between the throttling flange 18 and the inlet pipe 21 as an example.

[0059] Specifically, see Figure 7 The throttling flange 18 is arranged opposite to the pipe flange 23 provided on the matching end surface of the inlet pipe 21 and the throttling cylinder 13, and is connected by fastening bolts 25 to connect the throttling flange 18 and the pipe flange 23, so that the throttling device 1 can be connected to the inlet pipe 21. When disassembling, the throttling device 1 can be separated from the inlet pipe 21 by simply removing the fastening bolts 25.

[0060] Since there is a gap when the throttling flange 18 and the pipe flange 23 are connected, in order to prevent leakage of high-pressure fluid, a metal winding gasket 24 is provided between the throttling flange 18 and the pipe flange 23, so that the compression sleeve 15, the metal winding gasket 24 and the throttling flange 18 constitute a first sealing mechanism to prevent leakage of high-pressure fluid before entering the core body 14 from the inlet pipe 21.

[0061] Furthermore, an O-ring 26 is provided between the pressing sleeve 15 at the inner end of the throttling cylinder 13 and the metal winding gasket 24, so that the fastening screw 25, the pressing sleeve 15 and the O-ring 26 constitute a second sealing mechanism to prevent the high-pressure fluid from leaking after entering the core 14. Thus, the pressing sleeve 15, the metal winding gasket 24, the throttling flange 18 and the O-ring 26 cooperate to form a sealing device of the throttling device 1, and two layers of sealing are used to prevent the high-pressure fluid from leaking before and after entering the throttling device 1.

[0062] Compared with the solution of welding the throttling device 1 to the recovery pipe 2 in the prior art, a detachable connection between the throttling flange 18 and the pipe flange 23 is adopted, and the sealing cooperation with the compression sleeve 15, the metal winding gasket 24 and the O-ring 26 is realized to achieve quick disassembly and assembly and prevent leakage, and there is no need to cut off the recovery pipe 2 during disassembly, thereby reducing the loss cost.

[0063] The following examples illustrate the working process of the present invention in a specific application. It should be noted that the following content is only a specific application example of the present solution and does not constitute a limitation to the present solution.

[0064] When the high-pressure fluid in the recovery pipeline 2 enters the throttling cylinder 13 from the inlet 11 of the throttling device 1, the first sealing mechanism composed of the compression sleeve 15, the metal winding gasket 24 and the throttling flange 18 prevents the high-pressure fluid from leaking from the gap between the throttling flange 18 and the pipeline flange 23 in the inlet pipeline 21.

[0065] After the high-pressure fluid enters the core 14 of the throttling cylinder 13 from the inlet 11 of the throttling device 1, the second sealing mechanism composed of the fastening screw 25, the compression sleeve 15 and the O-ring 26 prevents the high-pressure fluid from leaking from the gap between the throttling flange 18 and the pipe flange 23 in the core 14.

[0066] The high-pressure fluid passes through several throttling and pressure-reducing sections 3 in the core body 14, enters the first-stage throttling and pressure-reducing section 31 from the throttling hole on the first-stage orifice plate 312, and then enters the intermediate-stage throttling and pressure-reducing section 32 through the two throttling holes vertically distributed on the first intermediate-stage orifice plate 322, and then enters the final-stage throttling and pressure-reducing section 33 through the two throttling holes horizontally distributed on the second intermediate-stage orifice plate 323, and finally enters the outlet pipe 22 from the outlet 12 of the throttling device 1 through the throttling hole on the final-stage orifice plate 332, so that the pressure of the high-pressure fluid is reduced under the action of the local resistance of the orifice plate, and at the same time, it needs to flow out through the throttling holes 172 in different directions and numbers, thereby effectively reducing the pressure and flow rate during the flow process, so that it enters the outlet pipe 22 in a low-pressure state suitable for recovery.

[0067] When the throttling device 1 needs to be maintained or replaced, the fastening bolts 25 are removed from the throttling flange 18 and the pipe flange 23 to separate the throttling device 1 from the inlet pipe 21 .

[0068] Next, the press sleeve 15 is removed from the end of the throttle cylinder 13 so that the core body 14 can be taken out from the throttle cylinder 13 .

[0069] Furthermore, the core body 14 can be separated into a plurality of sleeves 16 and orifice plates 17 by pulling out the buckles on the first-stage throttling and pressure-reducing section 31 , the final-stage throttling and pressure-reducing section 33 and the intermediate-stage throttling and pressure-reducing section 32 from the slots in turn.

[0070] Thus, the throttling device 1 can be quickly disassembled for maintenance. When replacing, the sleeve 16 and the orifice plate 17 are installed as the core 14, and the core 14 is placed in the throttling cylinder 13, connected and fixed by the pressing sleeve 15, and finally the throttling device 1 and the recovery pipe 2 are connected. This installation process is the reverse process of the disassembly process and will not be repeated here.

[0071] The quick-disassembly high-pressure water recovery device provided by the utility model is easy to install and remove through the snap connection cooperation of the sleeve 16 and the orifice plate 17 in the core body 14, and there is no gap with the throttling cylinder 13, so it is not easy to leak. The core body 14 and the throttling cylinder 13 are detachably connected by a pressing sleeve 15, so that the core body 14 can be quickly disassembled and assembled from the throttling cylinder 13; further, the throttling cylinder 13 is detachably connected to the recovery pipe 2 through a flange, and there is no need to cut off the recovery pipe during disassembly, which improves the disassembly efficiency and reduces the loss cost.
