In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0050] Please also read Figures 1 to 3 , the flow-guiding pulser provided by the embodiment of the present application is now described. The flow-guiding pulser comprises a valve body 100, a support member 200, a seesaw 300 and a cover 400; the valve body 100 has a fluid channel 101 and a mounting hole 102, the fluid channel 101 runs through the valve body 100, the mounting hole 102 is arranged on the side wall of the valve body 100 and communicates with the fluid channel 101; the support member 200 is fixed in the mounting hole 102; the support member 200 is provided with a first flow hole 201; the seesaw 300 is arranged in the mounting hole 102 and is rotatably connected to the support member 200, and the seesaw 300 can swing back and forth around the axis of the support member 200; the seesaw 300 is provided with a second flow hole 301; the cover 400 is connected to the valve body 100 at the opening of the mounting hole 102.
[0051] Compared with the prior art, the guide pulser provided in the embodiment of the present application has the following characteristics: in this embodiment, the seesaw 300 can swing back and forth around the axis of the support 200, so that the medium fluid passing through the first flow hole 201 and the second flow hole 301 changes in a pulsed manner. The pulsed fluid can produce intermittent impacts on the inner wall of the silo, and the material attached to the inner wall of the silo is alternately stressed, repeatedly squeezed and released, and produces a certain vibration, so that the bonded material clumps are easier to loosen and detach, thereby improving the cleaning effect and energy efficiency; and compared with the continuous fluid, the pulsed fluid has lower volume loss and energy loss, thereby reducing the cost of use.
[0052] In this embodiment, the mounting hole 102 is a cylindrical cavity, and the diameter of the mounting hole 102 is larger than the rotation radius of the rotating seesaw 300 .
[0053] In one embodiment of the present application, please refer to Figure 5 and Figure 6 The support member 200 includes a mounting plate 210, a first support plate 220 and a second support plate 230 which are distributed in a herringbone shape; the first support plate 220 and the second support plate 230 are both provided with a first flow hole 201.
[0054] In this embodiment, the support member 200 is designed in a herringbone shape, is easy to process, and has a certain strength, and can provide a strong support point for the rotation of the rotating seesaw 300. A plurality of first flow holes 201 can be provided on the first support sheet 220 and the second support sheet 230.
[0055] In one embodiment of the present application, please refer to Figure 1 and Figure 5 The mounting plate 210 is provided with a mounting groove 211 , and the rotating rocker 300 is movably connected in the mounting groove 211 .
[0056] In this embodiment, by providing the installation groove 211, the edge-turning rocker 300 can be installed, the structure is compact, and the space occupied is small, which can meet the requirements of miniaturized structural design.
[0057] Specifically, the support member 200 is a symmetrical herringbone structure, and the mounting piece 210 is formed by laminating and pressing sheet metal, and the two ends of the sheet metal are bent to form a first support piece 220 and a second support piece 230 respectively.
[0058] In one embodiment of the present application, please refer to Figure 5 and Figure 6 The seesaw 300 includes a guide plate 310 , a first swing plate 320 and a second swing plate 330 which are distributed in a herringbone shape; the first swing plate 320 and the second swing plate 330 are both provided with a second flow hole 301 .
[0059] In this embodiment, the entire process of the seesaw 300 can be processed by laser cutting and sheet metal bending technology, which is simple to process and has high precision.
[0060] In one embodiment of the present application, the angle between the guide plate 310 and the first swing plate 320 is in the range of 95°-155°; the width of the guide plate 310 is 0.1-1.2 times the width of the first swing plate 320. With such a configuration, the rotating seesaw 300 can automatically swing back and forth under the impact of the medium fluid without the need for other driving devices.
[0061] In this embodiment, please refer to Figure 7 and Fig. 9 Assuming that the stop angle θ is 15 degrees and the guide angle adjustment range is 95 degrees to 155 degrees, the full-angle rotation of the rotating seesaw 300 (twice the angle between the guide vane 310 and the fluid direction) varies from 20 degrees to 40 degrees. This angular stroke also basically determines the range of the pulsation frequency.
[0062] In this embodiment, the force analysis of the rotating seesaw 300 is as follows: Figures 7 to 9 As shown, the left stop position means that under the push of the medium fluid, the rotating seesaw 300 rotates to the left limit position in the flow direction, such as Fig. 9 The symmetrical position is when the seesaw 300 is rotated to the same direction of the flow direction, such as Figure 8 The right stop is the right limit position where the seesaw 300 is rotated to the flow direction, as shown in FIG. Figure 7 As shown. Assume that J is the angle between the guide vane 310 and the fluid direction (hereinafter referred to as the guide angle); F, Fb, and Fz are the forces on the first swinging piece 320, the second swinging piece 330, and the guide vane 310, respectively; A is the angle between the first swinging piece 320 or the second swinging piece 330 and the guide vane 310 (hereinafter referred to as the guide swing angle); L is the length of the first swinging piece 320 or the second swinging piece 330; K*L is the length of the guide vane 310 (K takes a value of 0.1-2.0); La, Lb, and Lz are the lengths of the force arms of the first swinging piece 320, the second swinging piece 330, and the guide vane 310, respectively. Among them, the guide angle J, the guide swing angle A, and the k value are three variables that affect the rotation rate of the seesaw 300.
[0063] Figures 10 to 13 This is a comparison diagram of the appearance of the guide pendulum angle and the limit change of K value. Fig.10 and Fig.11 When the guide swing angle is 155 degrees, the widths of the guide plate 310 are 0.1*L and 1.2*L respectively, which are the shapes of the rotating seesaw 300. Fig.12 and Fig.13When the guide swing angle is 95 degrees, the width of the guide plate 310 is 0.1*L and 1.2*L respectively, which are the shapes of the rotating seesaw 300. As can be roughly seen from the figure, the larger the guide swing angle is, the smaller the rotation stroke of the rotating seesaw 300 is. The larger the k value is (the wider the guide plate k*L is), the smaller the restoring torque is when rotating past the symmetric position, that is, the rotating seesaw 300 is more inclined to instability.
[0064] In this embodiment, taking the following data as an example, the fluid pressure P = 3.2 MPa (about 32.6 kgf / cm2), the height of the seesaw 300 is 2.6 cm, the guide angle is set to 115 degrees, the width of the first swing plate 320 is 1.2 cm, the width of the guide plate 310 is K*1.2=1.2Kcm, and the values of k are 0.1, 0.3, 0.6, 0.9, 1.1, and 1.2, respectively. A comparison curve of the composite moment can be obtained, as shown in FIG. Fig.14 As shown in the figure, it can be seen that the K value has a negative correlation with the synthetic torque. The larger the k value, the smaller the synthetic torque. Due to the synthetic torque, the rotating seesaw 300 is given acceleration, that is, rotational kinetic energy. Therefore, under the same kinetic energy, the larger the overall mass of the rotating seesaw 300, the smaller its rotation rate, that is, the longer the rotation period, and the smaller the swing frequency.
[0065] In summary, a trend diagram of the influence of the relationship between the guide angle and the length of the guide plate 310 on the performance of the rotating seesaw 300 can be obtained, as shown in FIG. Fig.15 As shown, the horizontal and vertical solid line segments in the figure do not represent blocks with clear boundaries, but are for intuitively showing the geometric deformation of the rotating seesaw 300 so that the pulse frequency and the steady state are distributed in different intervals.
[0066] In one embodiment of the present application, the angle between the guide plate 310 and the first swing plate 320 is equal to the angle between the guide plate 310 and the second swing plate 330 .
[0067] In this embodiment, the angle between the guide plate 310 and the first swing plate 320 is equal to the angle between the guide plate 310 and the second swing plate 330, that is, the first swing plate 320 and the second swing plate 330 are symmetrically arranged relative to the guide plate 310, which is conducive to the reciprocating swing of the seesaw 300.
[0068] In one embodiment of the present application, please refer to Figure 5 and Figure 6 The seesaw 300 further includes a reinforcing sheet 340 , which is connected to the guide sheet 310 , the first swing sheet 320 , and the second swing sheet 330 , respectively.
[0069] In this embodiment, by providing the reinforcing sheet 340 , the overall structural strength of the seesaw 300 can be improved, thereby increasing the service life of the seesaw 300 .
[0070] In one embodiment of the present application, please refer to Figure 5 and Figure 6 The reinforcing piece 340 is provided with an embedding groove 341 , the guide piece 310 , the first swing piece 320 and the second swing piece 330 are provided with an embedding protrusion 342 , and the embedding groove 341 and the embedding protrusion 342 are engaged with each other.
[0071] In this embodiment, by providing the embedding slot 341 and the embedding protrusion 342 , the rotating rocker 300 can be quickly assembled, and the installation is convenient and the reliability is high.
[0072] In one embodiment of the present application, the projection of the first flow hole 201 on the cross section of the valve body 100 and the projection of the second flow hole 301 on the cross section of the valve body 100 are arranged in a staggered manner, and the aperture of the first flow hole 201 is larger than the aperture of the second flow hole 301. In this arrangement, when the rotating seesaw 300 is swinging, when the medium fluid passes through the rotating seesaw 300 and the support member 200, the change in the distance between the first support plate 220 and the first swing plate 320 will cause a change in the medium fluid path, thereby causing a change in the flow rate per unit cross section of the fluid channel 101; the rotating seesaw 300 swings back and forth, thereby generating a pulse effect.
[0073] In this embodiment, please refer to Figure 1 and Figure 2 The cover 400 is provided with a maintenance wrench hole 401, and the maintenance wrench hole 401 can be a hexagonal countersunk hole, in which a hexagonal wrench can be placed, so as to facilitate the disassembly and assembly of the cover 400.
[0074] In another embodiment of the present application, see Figure 4 The cover 400 has a wrench position 402 protruding from the surface of the valve body 100, and the wrench position 402 can be matched with an external hexagonal wrench; a transparent window 403 is provided on the cover 400, through which the working state of the rotating rocker 300 can be conveniently observed.
[0075] In this embodiment, please refer to Figure 1 and Figure 2 The surface of the valve body 100 is provided with a directional mark 103, which may be in the shape of an arrow, for indicating the direction of fluid flow to prevent the diversion pulser from being installed in reverse.
[0076] The working principle of the flow-guiding pulser provided in this embodiment is also described in Figures 16 to 21 The three action processes of the rotating seesaw 300 are shown in the broken line cross-sectional diagram to show the opening and closing effects of the rotating seesaw 300 on the fluid channel 101.
[0077] like Fig.16 and Fig.17As shown, when the guide plate 310 is deflected to the right, the first swing plate 320 is farthest from the first support plate 220, and the fluid passes through the second flow hole 301 of the rotating seesaw 300 from the left end, passes through the angular gap of the maximum distance, and then passes through the first flow hole 201 of the first support plate 220 after a certain turn, and then flows out from the right end. At this time, under the action of the synthetic torque of the rotating seesaw 300, the rotating seesaw 300 rotates counterclockwise around the support member 200.
[0078] like Fig.18 and Fig.19 As shown, the seesaw 300 rotates to the symmetrical position; the angle between the first swing piece 320 and the support member 200 becomes smaller, the gap between the first swing piece 320 and the first support piece 220 is the middle distance, the fluid is blocked, and the flow rate is reduced. Then inertia causes the seesaw 300 to pass the symmetrical position.
[0079] like Fig. 20 and Fig.21 As shown, the seesaw 300 continues to rotate counterclockwise to the left offset position; the distance between the first swing plate 320 and the first support plate 220 is the smallest, the first flow hole 201 on the first support plate 220 is closed by the first swing plate 320, and the second flow hole 301 on the first swing plate 320 is closed by the first support plate 220, the fluid is close to being shut off, and the flow rate is close to zero.
[0080] Under the continuous action of the synthetic moment, the rotating seesaw 300 starts to deflect clockwise, then crosses the symmetrical position again and returns to the right deflection position. In this way, the fluid forms a rapid flow regulation and generates pulse fluctuations.
[0081] Theoretically, the maximum flow cross section of the seesaw 300 in this embodiment can be larger than the diameter area, so that the pressure peak is close to the upstream pressure. Since the closed surfaces are generated alternately when the left and right swing plates reach the stop points, the minimum pressure valley value can only reach half of the upstream pressure.
[0082] A complete pressure sequence is as follows: left stop (half pressure) -> forward rotation (pressure increase, greater than half) -> symmetrical position (full pressure) -> -> forward rotation (pressure decrease, greater than half) -> right stop (half pressure) -> reverse rotation (pressure increase, greater than half) -> symmetrical position (full pressure) -> reverse rotation (pressure decrease, greater than half) -> left stop (half pressure). In a full vibration cycle, there are two peaks (full pressure) and three valleys (half pressure).
[0083] This application also provides an injection part, please refer to Fig. 22 and Fig.23 The injection member includes a nozzle 500 and the above-mentioned flow-guiding pulser; the nozzle 500 is connected to one end of the valve body 100 and communicated with the fluid channel 101.
[0084] In this embodiment, by setting a flow-guiding pulser at one end close to the nozzle 500, the vibration transmission path of the medium fluid can be shortened and the impulse loss of the medium fluid pressure can be reduced. In the warehouse cleaning system, the nozzles 500 are arranged in the number of hundreds to thousands. If a single nozzle 500 reduces the consumption of the medium flow volume by 10-30%, the total amount of medium fluid saved will be very large. Therefore, setting a flow-guiding pulser has a significant effect on controlling energy consumption and improving comprehensive benefits.
[0085] In this embodiment, both ends of the valve body 100 are provided with threaded interfaces, which can be either external threaded interfaces or internal threaded interfaces, so as to facilitate the connection of components such as the nozzle 500.
[0086] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
