The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art in a specific case.
The invention will be described in detail below with reference to the drawings in connection with embodiments.
The device for eliminating the impact of water hammer comprises a weir flow tube set 2 and a support frame 1, wherein the device is arranged inside a liquid storage container 3, and the structure after installation can be schematically shown in figure 1.
The support frame 1 is arranged inside the liquid storage container 3, and the structure of the support frame 1 can be schematically shown in fig. 2. As shown in the figure, the support 1 comprises a top plate 11, a metal net 12 and a bottom plate 13, wherein the top plate 11 is parallel to the bottom plate 13 and is connected with the bottom plate 13 through the metal net 12, the bottom plate 13 is embedded into the wall of the liquid storage container 3, and the bottom plate 13 is uniformly provided with discharge openings 131.
The slice tube group 2 is arranged inside the support frame 1, and the slice tube group 2 comprises at least two coaxially arranged slice tubes 21, and a gap exists between the tube walls of two adjacent slice tubes 21.
The bottom plate 13 is fixedly connected with the bottom end of the weir flow tube 21, and a water inlet hole 111 is formed in the top plate 11, and the water inlet hole 111 is used for accommodating a water inlet pipe 112, so that the water inlet pipe 112 can be inserted into the inner portion of the innermost weir flow tube 21.
Preferably, the metal mesh 12 has a layered structure, and each metal mesh 12 is wrapped on the outer wall of the weir duct 21 of the corresponding layer.
Since the weir duct 21 is the first component through which the external liquid enters the reservoir 3, the strong impact force caused by the water hammer phenomenon acts directly on the weir duct 21, and radial vibration of the weir duct 21 occurs, which causes the rigid connection between the weir duct 21 and the bottom plate 13 to bear large stress, which in the long term causes damage to the device. At the same time, the noise generated by the vibration of the weir flow tube 21 can increase the amplitude of sound waves by vibrating the noise in the cavity inside the liquid storage container 3, thereby causing noise pollution inside the factory building and seriously affecting the physical and psychological health of staff.
Each layer of weir flow tube 21 is radially limited by the metal mesh 12, so that the stress applied to the connecting part at the bottom of the weir flow tube 21 can be dispersed when the weir flow tube 21 is impacted, and the service life of the device is remarkably prolonged. Meanwhile, since the side wall of the metal mesh 12 has a net structure, the metal mesh has elastic deformation capability, when the weir flow tube 21 vibrates, the side wall of the metal mesh 12 can generate resistance to the vibration, so that the amplitude of sound waves generated by the vibration is reduced, and the influence of noise is reduced from the root.
The slice tube group 2 in the present apparatus is used to attenuate the effects of water hammer level fluctuations. From the water inlet pipe 112, the liquid enters the weir flow pipe group 2, firstly enters the innermost weir flow pipe 21, when the innermost weir flow pipe 21 is full, the liquid can overflow to act as a weir to the second layer, when the second layer is full again, the liquid can flow to the third layer, and so on until the outermost weir flow pipe 21 is full, and the liquid medium can flow into the liquid storage container 3.
The slice flow tube group 2 with the layered structure can lead the liquid medium to form continuous deflection before entering the liquid storage container 3, the process can ensure that the impact force caused by the water hammer phenomenon does not directly act on the liquid in the liquid storage container 3, and the flow rate of the liquid entering the liquid storage container 3 is slowed down, thereby avoiding the liquid level fluctuation caused by the water hammer impact. At the same time, the continuous baffling can slow the flow velocity of the liquid, can deposit solid turbidity matters in the liquid, and the liquid medium discharged out of the weir flow tube set 2 is cleaner, so that the liquid quality in the liquid storage container 3 is improved.
As shown in fig. 3, to collect solid turbidity, the device further comprises a turbidity collector 4, wherein the turbidity collector 4 is arranged outside the liquid storage container 3, and the opening end of the turbidity collector 4 is inserted into the wall of the liquid storage container 3 and aligned with the bottom plate 13, so that the turbidity collector 4 is communicated with the weir flow tube set 2.
The turbidity collector 4 comprises: the collection funnel 41, the shaft 42, the flap 44 and the motor 43. The part inserted into the wall of the liquid storage container 3 is a straight wall section of the opening end of the collecting funnel 41, one end of the rotating shaft 42 penetrates through the collecting funnel 41 along the radial line of the straight wall section, the other end of the rotating shaft is connected with the output shaft of the motor 43, and a sealing gasket for preventing the liquid medium inside the turbidity collector 4 from leaking outside is arranged between the rotating shaft 42 and the collecting funnel 41. The turning plate 44 is arranged in the straight wall section of the collecting funnel 41, the turning plate 44 is fixed on the axis of the rotating shaft 42 and is rotationally connected with the collecting funnel 41 through the rotating shaft 42, and a drain pipe 45 for discharging turbid matters is further arranged at the bottom of the collecting funnel 41.
The motor 43 obtains working energy through an external power line, and converts the electric energy into torque on an output shaft, and the torque is transmitted to the turning plate 44 through the rotating shaft 42 connected with the output shaft, so that the turning plate 44 can perform turning action by taking the rotating shaft 42 as an axis.
Specifically, the turbidity collector 4 has two operating states in common. During the water inlet process, the motor 43 is in a stop state, at the moment, the turning plate 44 is parallel to the bottom plate 13, and the liquid medium in the weir flow tube set 2 is blocked by the turning plate 44 and cannot enter the turbidity collector 4, so that the liquid medium can perform baffling action on the weir flow tube 21 in a layered arrangement, and solid turbidity is deposited at the bottom of the weir flow tube set 2. During the sewage draining process, the motor 43 is started, the output torque of the motor makes the turning plate 44 generate an inclined angle of 5-25 degrees, at the moment, the inside of the collecting funnel 41 is not in a closed state, and solid turbidity matters deposited at the bottom of the weir flow tube set 2 flow into the inside of the collecting funnel 41 and are further discharged to the outside through the sewage draining tube 45.
Preferably, a waterproof rubber pad is provided on top of the flap 44, the diameter of the rubber pad being 1.1 times the diameter of the flap 44, and the thickness of the rubber pad beyond the edge of the flap 44 being one tenth of the rest. The waterproof rubber gasket is arranged to be favorable for realizing the sealing of the turbid matter collector 4, so that liquid is not fed into the collecting funnel 41 when the device is in a water inlet process, and the rubber gasket exceeding the edge of the turning plate 44 can seal a gap between the turning plate 44 and the collecting funnel 41, so that the sealing effect is further enhanced.
Alternatively, the motor 43 may perform a forward/reverse rotation switching operation during the sewage discharge process, so that the flap 44 is in a swing state. Since the solid turbidity matters deposited at the bottom of the slice tube group 2 are mostly granular, powder accumulation is formed between the turbidity matters, which causes clogging of the discharge port 131, thereby affecting the discharge effect of the turbidity matters. The swing of the turning plate 44 damages the accumulation effect of the turbidity matters, so that the accumulated large-scale turbidity matters are dispersed, and the turbidity matters are discharged conveniently.
The following describes the effects of the above scheme:
the invention provides a device capable of eliminating the influence of water hammer, the impact force of water flow is weakened through the continuous baffling environment manufactured by the weir flow tube set 2, so that the liquid flowing into the liquid storage container 3 is more stable, meanwhile, the bottom of the weir flow tube set 2 is provided with a turbidity collector 4, solid turbidity in a liquid medium can be collected, the turbidity is prevented from being dispersed into the liquid storage container 3, and the cleanliness of the liquid in the liquid storage container 3 is improved.
The structure of the internal slice tube group 2 of the present apparatus will be further described with reference to the examples.
Example 1
Based on the above, this embodiment provides a vertical placement of the slice tube stack 2 inside the reservoir 3, the mechanism of which can be illustrated by fig. 4.
In this embodiment, the bottom plate 13 is embedded in the bottom surface of the liquid storage container 3, the support frame 1 is perpendicular to the bottom surface of the liquid storage container 3, the weir flow tube set 2 is perpendicular to the bottom plate 13, three weir flow tubes 21 are included in the weir flow tube set 2, the lengths of the three weir flow tubes 21 are sequentially reduced from inside to outside, and a gap is arranged between the top of the innermost weir flow tube 21 and the top plate 11.
Specifically, the diameter of the innermost weir flow tube 21 is 80mm, the length is 120cm, the diameter of the second weir flow tube 21 is 100mm, the length is 100cm, the diameter of the outermost weir flow tube 21 is 125mm, and the length is 80cm. The wall thickness of each of the three weir flow tubes 21 was 5mm and was made of food grade 304 stainless steel.
The inlet pipe 112 is inserted into a weir flow pipe 21 of diameter 80mm and a liquid medium, by way of example and not limitation, water in an environment of 4 c is injected into the pipe. When the injected liquid reaches 4.62L, the innermost weir flow tube 21 is full, and the liquid will have a weir flow phenomenon at the top end surface of the innermost weir flow tube 21, and the liquid discharged from the weir flow enters the second weir flow tube 21. After continuing to fill with 1.42L of liquid, the second weir flow tube 21 fills, at which time the liquid will have a weir flow phenomenon at the top end of the second weir flow tube 21, and the liquid from the weir flow enters the third weir flow tube 21. After the continuous injection of 1.95L of liquid, the third layer of weir flow tube 21 is full, and at this time, the liquid will have a weir flow phenomenon on the top end surface of the third layer of weir flow tube 21, and the liquid discharged from the weir flow enters the liquid storage container 3.
When the water inlet process is finished, the supply of liquid to the water inlet pipe 112 is stopped, 7.99L of liquid is stored in the weir flow tube set 2, the liquid is discharged to the outside through the turbidity collector 4 when the sewage process is performed, and the liquid can wash out solid turbidity, so that the turbidity collecting effect is enhanced.
Preferably, the top end surface of the weir flow tube 21 is a convex arcuate surface 211, a longitudinal cross-sectional view of which is shown in fig. 5. In this embodiment, the slice tube group 2 reduces the impact of the water hammer on the liquid level by means of the slice effect, i.e. the phenomenon that the liquid slowly overflows through the top of the barrier. In order to ensure that all the liquid flowing out of the inner weir flows into the next weir flow tube 21, the top end surface of each weir flow tube 21 is a convex arc surface 211, and the arc surface 211 can ensure that the fluid flowing out of the weir flows closely to the outer wall of the weir flow tube 21, thereby avoiding the generation of a weir flow vacuum region and ensuring that the liquid sequentially passes through each weir flow tube 21.
Example two
Based on the above-described solution and differing from the first embodiment, this embodiment provides a slice tube set 2 placed vertically inside a liquid storage vessel 3, the structure of which can be illustrated by fig. 6.
In this embodiment, the bottom plate 13 is embedded in the bottom surface of the liquid storage container 3, the support frame 1 is perpendicular to the bottom surface of the liquid storage container 3, and the weir flow tube set 2 is perpendicular to the bottom plate 13. The weir flow tube group 2 comprises three weir flow tubes 21 in total, the lengths of the three weir flow tubes 21 are the same, the top end of each weir flow tube 21 is fixedly connected with the top plate 11, and the side wall of each weir flow tube 21 is provided with a weir flow hole 22.
The slice tube group 2 in this embodiment achieves a liquid flow between the layers of slice tubes 21 through slice holes 22. After the water inlet pipe 112 conveys the liquid into the innermost weir flow pipe 21, the liquid accumulates in the innermost weir flow pipe 21 until the liquid level is tangential to the lower edge of the weir flow aperture 22, at which point the liquid flows from the weir flow aperture 22 into the interior of the second weir flow pipe 21, in the same manner as the weir flow process of the innermost weir flow pipe 2, and when the liquid level reaches the level of the weir flow aperture 22 on the second weir flow pipe 21, the liquid flows to the outermost weir flow pipe 21. When the height of the liquid in the outermost weir flow tube 21 reaches the height of the weir 22 on the wall of the tube, the liquid flows into the reservoir 3.
To enhance the throughput of the slice tube group 2 described in this embodiment, the slice holes 22 should be arranged close to the top of the slice tube 21.
Example III
Based on the above-described scheme and differing from the first and second embodiments, this embodiment provides a slice tube group 2 that can be placed inside a liquid storage container 3 at an arbitrary angle, and its structure is shown in fig. 7.
In this embodiment, the top plate 11 and the bottom plate 13 of the support frame 1 are respectively embedded into the left and right side walls of the liquid storage container 3, the horizontal position of the top plate 11 is higher than that of the bottom plate 13, the weir flow tube group 2 comprises three weir flow tubes 21, the lengths of the three weir flow tubes 21 are the same, the upper end and the lower end of the weir flow tube 21 are respectively fixedly connected with the top plate 11 and the bottom plate 13, and a weir flow hole 22 is arranged on the side wall of the weir flow tube 21.
By way of example and not limitation, the weir flow apertures 22 on each weir flow tube 21 are equally positioned at the top of the side wall of the weir flow tube 21 and the weir flow apertures 22 are equally oriented toward the top of the reservoir 3.
In this embodiment, the weir flow tube set 22 can be placed inside the liquid storage container 3 at various angles, so that the adaptability of the device to various liquid storage containers 3 is improved. In operation, the liquid medium moves from the inner weir flow tube 21 to the outer weir flow tube 21 through the weir flow holes 22 and eventually flows into the reservoir 3.
In order to facilitate the discharge of the turbidity matters inside the slice tube set 2, the top end of the slice tube set 2 is higher than the bottom end, and when the blowdown process is performed, the liquid medium inside the slice tube set 2 flows to the turbidity matters collector 4 due to the gravity effect, and along with the flushing of the liquid, the solid turbidity matters are also discharged out of the slice tube set 2.
The motor 43 described in this application may be a GM37-520 type motor from TTMOTOR, and the internal structure and circuit connections are well known and will not be described in detail herein.
The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
