Description

Technical Field

[0001] The present invention belongs to the technical field of engineering components, and in particular relates to a valve, and more particularly to a wastewater conveying device and a working method thereof. Background Art

[0002] During the feeding process of industrial wastewater storage tanks, the problems of liquid surface impact and waste gas escape caused by sudden changes in flow rate have long plagued engineering practice.

[0003] The commonly used technology for controlling flow rate is a flow meter coupled with a dynamic regulating valve. However, this method suffers from a core flaw: as the valve opening increases, the kinetic energy of the fluid in the pipeline increases exponentially, creating a transient high-speed jet that causes violent turbulence in the liquid level within the tank. This axial impact not only accelerates the decomposition of volatile organic compounds (VOCs) (experimental data shows that increasing the flow rate from 0.5 m / s to 1.2 m / s increases hydrogen sulfide emissions by 3.8 times), but also triggers tank pressure fluctuations, forcing the breathing valve to open and close frequently, resulting in "excessive breathing" losses.

[0004] Therefore, how to avoid the formation of instantaneous high-speed jets when the fluid velocity increases is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of related technology. Summary of the Invention

[0006] The embodiments of the present disclosure at least provide a wastewater conveying device and a working method thereof.

[0007] In a first aspect, an embodiment of the present disclosure provides a wastewater conveying device, comprising: A delivery pump, which is arranged on one side of the liquid storage tank; An extension pipe, the inner end of which is located in the liquid storage tank and communicates with the water pipe, and the outer wall of the extension pipe is evenly distributed with a plurality of radial guide holes along the circumference; An adjustment assembly, located at the inner end of the extension tube, includes: A positioning plate is coaxially arranged with the extension tube, with a gap between the outer wall and the inner wall of the extension tube; A linkage member, which is rotatably arranged on the side wall of the positioning plate; A plurality of adjustment plates are slidably arranged on the side walls of the positioning plate and are adapted to abut against the outer walls of the linkage members; Wherein, if the fluid has a first flow rate, the linkage member rotates circumferentially to push each adjustment plate to slide outward to close the radial guide hole, and the fluid flows into the liquid storage tank in the axial direction through the gap; If the fluid has a second flow rate, the regulating piece slides inwardly to reset, and each regulating piece and the positioning plate are adapted to mitigate the axial impact of the fluid, so that the fluid flows into the liquid storage tank through each radial guide hole.

[0008] In an optional embodiment, the adjusting piece is arc-shaped, and a protrusion is provided on its outer wall, and the radial thickness of the protrusion is not less than the wall thickness of the extension tube; When the linkage member pushes each adjusting piece to slide outward, the protrusion is inserted into the radial guide hole to clean the impurities in the radial guide hole and close the radial guide hole.

[0009] In an optional embodiment, a plurality of push blocks are evenly distributed circumferentially on the outer wall of the linkage member, and the outer wall of the push block is in an arc shape; The inner wall of the adjusting plate is provided with an adjusting block along the radial direction. The adjusting block is radially slidably arranged on the side wall of the positioning plate through a guide rail, and one adjusting block corresponds to one pushing block; When the linkage member rotates circumferentially, the pushing block pushes the adjusting block to slide radially outward until the protruding block is inserted into the radial guide hole.

[0010] In an optional embodiment, the axial length of the adjustment plate is greater than the axial length of the radial guide hole; wherein, when each adjustment plate slides inward to abut, the adjustment plate is suitable for closing the gap between the outer wall of the positioning plate and the inner wall of the extension tube.

[0011] In an optional embodiment, a driving motor is provided on a side wall of the positioning plate away from the linkage member, and the linkage member is sleeved on an outer wall of a rotating shaft of the driving motor.

[0012] In an optional embodiment, a positioning tube is provided at the inner end of the extension tube, and the outer diameter of the positioning tube is smaller than the inner diameter of the extension tube; A filter disc is provided at one end of the positioning tube away from the extension tube. The filter disc is provided with a plurality of filter holes, and the filter holes are suitable for filtering large particles of impurities in the intercepted fluid.

[0013] In an optional embodiment, a cutting blade is sleeved on the outer wall of the rotating shaft of the driving motor, and the side wall of the cutting blade is in contact with the side wall of the filter disc; When the driving motor drives the cutting blade to rotate, the cutting blade is suitable for cutting large particles of impurities that block the filter holes.

[0014] In an optional embodiment, a plurality of positioning strips are evenly distributed axially on the inner wall of the extension tube, and the circumferential length between two adjacent positioning strips is not less than the circumferential length of the outer wall of the adjustment piece.

[0015] In an optional embodiment, a barrier tube is sleeved on the outer wall of the extension tube, and the inner diameter of the barrier tube is larger than the outer diameter of the extension tube; The barrier tube is fixed to the outer wall of the extension tube through ribs, and the end of the barrier tube is fixed to the inner wall of the liquid storage tank.

[0016] In a second aspect, the present disclosure also provides a method for operating a wastewater conveying device, the method comprising: If the fluid has a first flow rate, the linkage rotates circumferentially to push the adjustment plates to slide outward to close the radial guide holes, and the fluid flows into the liquid storage tank in the axial direction through the gap; If the fluid has a second flow rate, the regulating piece slides inwardly to reset, and each regulating piece and the positioning plate are adapted to mitigate the axial impact of the fluid, so that the fluid flows into the liquid storage tank through each radial guide hole.

[0017] The present invention has the beneficial effect of providing a wastewater conveying device and operating method thereof, wherein, through the configuration of the regulating assembly, when the flow rate of water delivered by the delivery pump to the liquid storage tank is a first flow rate (a relatively slow flow rate of 0.3-0.7 m / s), the regulating plates slide outward to close the radial guide holes, allowing water to flow axially into the liquid storage tank through the gap between the outer wall of the positioning plate and the inner wall of the extension tube. When the flow rate of water delivered by the delivery pump to the liquid storage tank is a second flow rate (a faster flow rate of 0.7-1.5 m / s), the water flow in the extension tube is instantaneously accelerated, causing the kinetic energy of the water to increase exponentially. At this time, the regulating plates return to their original position and slide inward to open the radial guide holes. After being blocked by the side walls of the linkage and the inner walls of the regulating plates, the water flows radially outward through the radial guide holes along the extension tube, thereby reducing the potential energy of the water impacting the liquid surface in the liquid storage tank and avoiding the problems of liquid surface impact and waste gas escape caused by sudden changes in flow rate.

[0028] Research has found that the commonly used flow meter and dynamic control valve combination to control flow rate in related technologies has a core flaw: when the valve opening increases, the kinetic energy of the fluid in the pipeline increases exponentially, forming an instantaneous high-speed jet, which causes violent turbulence in the liquid level in the tank. This axial impact not only accelerates the decomposition of volatile organic compounds (VOCs) (experimental data shows that when the flow rate increases from 0.5m / s to 1.2m / s, the amount of hydrogen sulfide emitted increases by 3.8 times) but also causes tank pressure fluctuations, forcing the breathing valve to open and close frequently, resulting in "excessive breathing" losses.

[0029] Therefore, how to avoid the formation of instantaneous high-speed jets when the fluid velocity increases is a technical problem that urgently needs to be solved in this field.

[0030] The defects in the above solutions and the causes of their occurrence are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0033] like Figures 1 to 6 As shown, at least one embodiment provides a wastewater conveying device, comprising: a delivery pump 1, disposed on one side of a liquid storage tank 2; an extension tube 3, the inner end of which is located within the liquid storage tank 2 and connected to a water pipe 10, and a plurality of radial guide holes 30 uniformly distributed around the outer wall of the extension tube 3; the extension tube 3 passes through the liquid storage tank 2 and is located at the upper portion of the liquid storage tank 2 to facilitate conveying wastewater into the liquid storage tank 2; and a regulating assembly 4, located at the inner end of the extension tube 3, adapted to adjust the flow rate and direction of wastewater flowing into the liquid storage tank 2. It includes: a positioning plate 41, which is coaxially arranged with the extension tube 3, and a gap is provided between the outer wall and the inner wall of the extension tube 3; a linkage member 42, which is rotatably arranged on the side wall of the positioning plate 41; and a plurality of adjustment plates 43, which are slidably arranged on the side wall of the positioning plate 41 and are suitable for abutting against the outer wall of the linkage member 42. When the fluid has a first flow rate (the flow rate at this time is relatively slow, the flow rate is 0.3-0.7m / s), the linkage member 42 rotates circumferentially to push each adjustment plate 43 to slide outward to close the radial guide hole 30, and the fluid flows into the liquid storage tank 2 in the axial direction through the gap. Figure 2 and Figure 5 If the fluid reaches the second flow rate (the flow rate is accelerated at this time, the flow rate is 0.7-1.5m / s), the adjustment plate 43 slides inward to reset, and each adjustment plate 43 and the positioning plate 41 are suitable for slowing down the axial impact of the fluid, so that the fluid flows into the liquid storage tank 2 through each radial guide hole 30. Figure 2 F1 represents the flow direction of the wastewater. By setting the adjustment assembly 4, when the water flow rate delivered by the delivery pump 1 to the liquid storage tank 2 reaches the first flow rate (the flow rate at this time is relatively slow, 0.3-0.7 m / s), each adjustment plate 43 slides outward to close the radial guide hole 30, allowing the water to flow axially into the liquid storage tank 2 through the gap between the outer wall of the positioning plate 41 and the inner wall of the extension tube 3. When the water flow rate delivered by the delivery pump 1 to the liquid storage tank 2 is the second flow rate (the flow rate at this time is faster, the flow rate is 0.7-1.5m / s), the water flow in the extension pipe 3 is instantaneously accelerated, and the kinetic energy of the water increases exponentially. At this time, each adjustment piece 43 slides inward to open the radial guide hole 30. The water flow is blocked by the side wall of the linkage 42 and the inner wall of each adjustment piece 43, and then flows through the radial guide hole 30 and flows radially outward along the extension pipe 3, reducing the impact potential energy of the water flow on the liquid surface in the liquid storage tank 2, and avoiding the problem of liquid surface impact and exhaust gas escape in the liquid storage tank 2 caused by the sudden change in flow rate.

[0034] Reference Attachment Figure 4 The regulating plate 43 is arc-shaped, with a protrusion 431 disposed on its outer wall. The radial thickness of the protrusion 431 is no less than the wall thickness of the extension tube 3. When the drive motor 410 drives the linkage 42 to rotate, the push block 421 on the outer wall of the linkage 42 pushes the adjustment block 432 on the inner wall of the regulating plate 43, thereby enabling the regulating plate 43 to slide radially outward. When the linkage 42 pushes each regulating plate 43 outward, the protrusion 431 inserts into the radial guide hole 30, clearing impurities from the radial guide hole 30 and closing the radial guide hole 30. Closing the radial guide hole 30 here refers to inserting the protrusion 431 into the radial guide hole 30 to reduce its opening. At the first flow rate (the flow rate is relatively slow at this time, 0.3-0.7 m / s), wastewater mostly flows into the liquid storage tank 2 through the gap between the positioning plate 41 and the extension tube 3. The positioning disk 41 is radially provided with a plurality of linear slide rails, and the side walls of the linear slide rails are provided with return springs. One end of the return spring is provided on the side wall of the adjusting piece 43. The adjusting piece 43 is slidably adapted to the linear slide rails. The setting of the linear slide rails can ensure the stability of the radial sliding of the adjusting piece 43, and the setting of the return spring, after the pushing block 421 and each adjusting block 432 are misaligned, the return spring drives the adjusting piece 43 to move toward the axial direction of the positioning disk 41. Figure 4 F1 in the figure indicates the flow direction of wastewater.

[0035] Reference Attachment Figure 2 The outer wall of the linkage member 42 is evenly distributed with several push blocks 421 circumferentially. The outer wall of the push blocks 421 is arc-shaped. The push blocks 421 extend circumferentially along the outer wall of the linkage member 42, and the distance between the outer wall of the push blocks 421 and the axis of the linkage member 42 gradually increases from one end of the push block 421 to the other end. The inner wall of the adjustment plate 43 is radially provided with adjustment blocks 432. The adjustment blocks 432 are radially slidably arranged on the side wall of the positioning plate 41 via guide rails, and each adjustment block 432 corresponds to one push block 421. When the linkage member 42 rotates circumferentially, the push blocks 421 push the adjustment blocks 432 to slide radially outward until the protrusions 431 are inserted into the radial guide holes 30. When the push blocks 421 and the adjustment blocks 432 are misaligned, each adjustment plate 43 returns to its original position and slides under the elastic force of the return spring.

[0036] Reference Attachment Figure 4The axial length of the regulating piece 43 is greater than the axial length of the radial guide hole 30. When the wastewater flow rate reaches the second flow rate (the flow rate is accelerated at this time, with a flow rate of 0.7-1.5m / s), the drive motor 410 drives the linkage 42 to rotate until the push block 421 and the regulating block 432 are misaligned. When each regulating piece 43 slides inward to return to contact, the regulating piece 43 is suitable for closing the gap between the outer wall of the positioning plate 41 and the inner wall of the extension tube 3. At this time, each radial guide hole 30 is opened, and the wastewater with an increased flow rate first contacts the linkage 42 and the inner wall of each regulating piece 43, thereby blocking the flow rate and redirecting the water flow toward the radial guide hole 30. The wastewater eventually flows into the liquid storage tank 2 through the radial direction of the extension tube 3. Furthermore, in order to reduce the impact force of wastewater on the liquid surface in the liquid storage tank 2, a blocking tube 20 is fixed to the inner wall of the liquid storage tank 2. The blocking tube 20 is located outside the extension tube 3. The inner diameter of the blocking tube 20 is larger than the diameter of the extension tube 3. When the wastewater flows outward through the radial guide hole 30, the blocking tube 20 is suitable for blocking the water flow again and changing the direction of the water flow, so that the wastewater flowing outward through the radial guide hole 30 flows into the liquid storage tank 2 along the axial direction of the blocking tube 20.

[0037] Continue to refer to the attached Figure 4 A driving motor 410 is provided on the side wall of the positioning plate 41 away from the linkage member 42 , and the linkage member 42 is sleeved on the outer wall of the rotating shaft of the driving motor 410 .

[0038] Reference Attachment Figure 3 A positioning tube 31 is provided at the inner end of the extension tube 3. The outer diameter of the positioning tube 31 is smaller than the inner diameter of the extension tube 3. The arrangement of the positioning disc 41 and the positioning tube 31 ensures that, even at the first flow rate (which is relatively slow, at 0.3-0.7 m / s), the filter disc 32 not only filters and intercepts large particles of impurities in the wastewater as it flows through the positioning tube 31, but also further reduces the flow rate. A filter disc 32 is provided at the end of the positioning tube 31 distal from the extension tube 3. The filter disc 32 is provided with a plurality of filter holes 33 adapted to filter and intercept large particles of impurities in the fluid. A cutting blade 34 is secured to the outer wall of the rotating shaft of the drive motor 410. The sidewalls of the cutting blade 34 engage the sidewalls of the filter disc 32. When the drive motor 410 drives the cutting blade 34 to rotate, the cutting blade 34 is adapted to cut through large particles of impurities that clog the filter holes 33. Figure 3 F1 in the figure indicates the flow direction of wastewater.

[0039] Reference Attachment Figure 4The extension tube 3 has a plurality of positioning bars 35 evenly distributed axially along its inner wall. The circumferential length between two adjacent positioning bars 35 is not less than the circumferential length of the outer wall of the adjustment piece 43. The positioning bars 35 prevent the adjustment piece 43 from shaking relative to the extension tube 3 when each adjustment piece 43 moves outward to abut against the inner wall of the extension tube 3.

[0040] The specific working principle is as follows: Reference Attachment Figure 6 When the water flow rate delivered by the delivery pump 1 to the liquid storage tank 2 is the first flow rate (the flow rate at this time is slow, 0.3-0.7 m / s), the driving motor 410 drives the positioning plate 41 to rotate, so that the adjustment plate 43 slides outward to close the radial guide hole 30, so that the water flows into the liquid storage tank 2 in the axial direction through the gap between the outer wall of the positioning plate 41 and the inner wall of the extension tube 3. Figure 6 In the figure, F2 indicates the rotation direction of the linkage, and F3 indicates the outward sliding direction of the adjustment plate.

[0041] Reference Attachment Figure 5 When the water flow rate delivered by the delivery pump 1 to the liquid storage tank 2 is the second flow rate (the flow rate at this time is faster, the flow rate is 0.7-1.5m / s), the water flow in the extension pipe 3 is instantaneously accelerated, and the kinetic energy of the water increases exponentially. The drive motor 410 drives the positioning plate 41 to rotate so that the push block 421 and the adjustment block 432 are misaligned. At this time, each adjustment piece 43 slides inward to open the radial guide hole 30. After being blocked by the side wall of the linkage 42 and the inner wall of each adjustment piece 43, the water flow passes through the radial guide hole 30 and flows radially outward along the extension pipe 3, reducing the impact potential energy of the water flow on the liquid surface in the liquid storage tank 2, and avoiding the impact of the liquid surface in the liquid storage tank 2 and the escape of exhaust gas caused by the sudden change in flow rate.

[0042] At least one embodiment provides a method for operating a wastewater conveying device, the method comprising: If the fluid has a first flow rate, the linkage member 42 rotates circumferentially to push the adjustment plates 43 to slide outward to close the radial guide holes 30, and the fluid flows into the liquid storage tank 2 in the axial direction through the gap; If the fluid reaches the second flow rate (the flow rate is accelerated at this time, the flow rate is 0.7-1.5m / s), the adjustment plate 43 slides inward to reset, and each adjustment plate 43 and the positioning plate 41 are suitable for slowing down the axial impact of the fluid, so that the fluid flows into the liquid storage tank 2 through each radial guide hole 30.
