Description

Technical Field

[0001] The invention belongs to the technical field of filtration and separation, and particularly relates to a water spray backwashing microfilter for a channel. Background Art

[0002] Drip irrigation is a form of efficient water-saving irrigation in agriculture. Water is transported to the fields through pipes, and the drippers on the pipes drip the irrigation water out of the pipes to irrigate the crops and ensure the water needs of crop growth. The water used for drip irrigation must first be filtered to remove impurities in the water before it can be supplied to the drip irrigation system. Otherwise, the impurities will clog the drip emitters and cause ineffective irrigation.

[0003] The existing technology has the following problems: the water source for ordinary drip irrigation comes from a pond or reservoir equipped with a pre-pump filter. This water source is a relatively static water flow, but for flowing water bodies (such as rivers or channels with flowing water inside), there is a lack of the necessary filtering and water-taking equipment to utilize the kinetic energy of the water source, resulting in this water source not being well applied to drip irrigation projects.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The flowing water source of the present invention is first coarsely filtered through the water trough on the conical shield, and then finely filtered through the filter disc to ensure that there are no impurities in the water source during drip irrigation, avoiding clogging of the drip irrigation nozzle. The backwash nozzle of the present invention backwashes the filter disc to avoid clogging of the outside of the filter disc affecting the filtering effect. The coarse matter filtered on the outside of the conical shield is moved by the toggle arm and the conical structure of the conical shield, combined with the impact of the water body on the outside of the conical shield, so that the filtered coarse matter flows along the water source and the conical structure of the conical shield directly backward, avoiding clogging of the front end of the conical shield.

On the other hand, it avoids invalid backwash caused by rotation in the same direction.

[0018] 3. The traveling bevel gear of the present invention meshes and travels on the guide rail bevel gear, and a pumping structure is formed in the auxiliary cylinder. Since the auxiliary cylinder and the backwash nozzle are respectively arranged on both sides of the filter disc, the backwash filtration anti-blocking design on one side of the filter disc and the water pressure resistance design during backwashing on the other side are realized, thereby maximizing the filtering effect of the filter disc on the water source. At the same time, the device of the present invention is integrated with the channel and the pump station to realize the coordinated use of the present invention, the channel and the pump station.

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figures 1-10As shown, the present invention provides a channel water spray backwash microfilter, including a machine chamber assembly 100, the machine chamber assembly 100 includes a water tank 101, the front end of the water tank 101 is rotatably provided with a filter disc 104 for filtering a flowing water source, one side of the filter disc 104 is provided with a driving flushing arm assembly 200 for driving the filter disc 104 to perform displacement filtration and to perform anti-blocking backwashing on the filter disc 104, and the other side of the filter disc 104 is provided with a water flow driving paddle assembly 300 for utilizing the kinetic energy of the flowing water source, and the water flow driving paddle assembly 300 is provided with a water pressure guide module near the end of the filter disc 104 to avoid water pressure confrontation during backwashing.

[0032] In a preferred embodiment, see Figure 4 and Figure 5 An inner arm 114 is fixedly provided inside the water tank 101, and a water intake 112 and a water diversion pipe 113 are provided at one end of the water tank 101, a reversing bevel gear 111 and a guide rail bevel gear 105 are provided at the other end of the water tank 101, a conical shield 107 is fixedly provided on the front end warehouse body of the water tank 101 through a U-shaped arm 110, and a base 102 is fixedly provided at the bottom of the water tank 101, an inner conical groove 108 and a water groove 106 are respectively provided inside and at the front end of the conical shield 107, a rotating ring 109 is rotatably provided between the conical shield 107 and the water tank 101, and a first conical gear ring 103 is fixedly provided on the side of the filter disc 104 away from the guide rail bevel gear 105.

[0033] In this embodiment, the water intake 112 is used for inserting the water intake pipe of the channel water pump, thereby facilitating water intake of the channel water pump.

[0034] Secondly, the bottom of the water diversion pipe 113 is used to supply backwash water to the driven flushing arm assembly 200, and the top of the water diversion pipe 113 is connected to the water outlet branch separated from the channel water pump through a pipeline. In this way, water supply for backwashing is achieved.

[0035] In a preferred embodiment, see Figure 6 The driven flushing arm assembly 200 includes a hollow tube shaft 201 , a branch pipe 202 with a backwash nozzle 203 is fixedly provided at one end of the hollow tube shaft 201 , and a second conical gear ring 204 is fixedly provided between the two ends of the branch pipe 202 .

[0036] In this embodiment, the middle shaft of the empty tube shaft 201 is rotatably set on the inner arm 114, and the end of the empty tube shaft 201 away from the backwash nozzle 203 is rotatably set on the outside of the water tank 101 and rotatably connected to the end of the water diversion pipe 113. In this way, the rotation of the empty tube shaft 201 in the water tank 101 is realized, and the connection with the water diversion pipe 113 is ensured during rotation.

[0037] Next, please refer to Figure 2 and Figure 9 The branch pipe 202 is arranged on the side of the filter disc 104 away from the guide bevel gear 105, and the end of the hollow tube shaft 201 close to the branch pipe 202 is rotatably arranged on the filter disc 104 and extends to the side of the filter disc 104 close to the guide bevel gear 105, the shaft body of the paddle shaft 301 away from the toggle arm 302 is fixedly connected to the outer shell of the auxiliary tube 304, and the cross arm 307 on the air guide cover 306 is fixedly connected to the shaft body of the hollow tube shaft 201 close to the branch pipe 202. In this way, the hollow tube shaft 201 and the paddle shaft 301 are rotatably connected.

[0038] In this implementation, see Figure 9 The second conical gear ring 204 on the branch pipe 202 and the first conical gear ring 103 on the filter disc 104 are respectively located on both sides of the reversing bevel gear 111. The second conical gear ring 204 and the first conical gear ring 103 are respectively engaged with both sides of the reversing bevel gear 111. Through the engagement between the second conical gear ring 204 and the first conical gear ring 103 of the reversing bevel gear 111, a synchronously rotating and reverse structure is formed between the backwash nozzle 203 on the branch pipe 202 and the filter disc 104. The top of the filter disc 104 is not completely immersed in water. Through this transposition filtering structure, the top and bottom of the filter disc 104 are transposed, and the idle disc body at the top is aligned with the bottom disc body. The discs used for partial filtration are exchanged to share the pressure of filtration of the filter discs at the same position. At the same time, the filter disc 104 of the present invention is set to a structure that rotates in the opposite direction to the backwash nozzle 203. In this way, the backwash effect of the backwash nozzle 203 on the filter disc 104 is guaranteed. Because if the rotation direction of the filter disc 104 is set to be the same direction as the rotation direction of the backwash nozzle 203, if there is no speed difference or the speed difference is very small between the backwash nozzle 203 and the filter disc 104, this will cause the backwash nozzle 203 to still backwash the same position of the filter disc 104 or the cycle of backwashing the entire disc will be long. The relative reversal structure of the present invention completely avoids the above problem.

[0039] In a preferred embodiment, see Figure 7 The water flow driven paddle assembly 300 includes a paddle shaft 301 , a toggle arm 302 is fixedly provided at one end of the paddle shaft 301 , and a driving paddle blade 303 is fixedly provided on the middle shaft body of the paddle shaft 301 .

[0040] In this embodiment, the paddle shaft 301 is rotatably mounted on the cover at one end of the conical shield 107 away from the water tank 101 , thereby enabling installation of the paddle shaft 301 and facilitating conversion of the impact force exerted on the driving blades 303 .

[0041] Secondly, the toggle arm 302 is located on the outer cover of the conical shield 107, which facilitates cleaning of the outer cover of the conical shield 107.

[0042] Furthermore, the driving blade 303 is located in the inner conical groove 108 of the conical shield 107. This inner conical structure increases the impact force on the driving blade 303.

[0043] In a preferred embodiment, see Figure 7 and Figure 8 The water pressure guide module includes an auxiliary cylinder 304, an inner shaft 308 is rotatably provided inside the auxiliary cylinder 304, and a slag discharge pipe 305 is fixedly provided at the bottom of the auxiliary cylinder 304, a traveling bevel gear 309 is fixedly provided on the top of the inner shaft 308, a guide cover 306 with a cross arm 307 is fixedly provided at the front end of the auxiliary cylinder 304, a protrusion 310 is fixedly provided on the inner wall of the auxiliary cylinder 304, and a plurality of linkage arc plates 311 are rotatably provided on the periphery of the inner shaft 308, a resistance spring 312 is fixedly provided between the linkage arc plate 311 and the inner shaft 308, and a water pumping chamber 313 is formed between the two linkage arc plates 311.

[0044] In this embodiment, the auxiliary cylinder 304 is located on the side of the guide rail bevel gear 105 away from the filter disc 104 , and the travel bevel gear 309 on the top of the inner shaft 308 engages and rotates on the guide rail bevel gear 105 to achieve follow-up driving of the inner shaft 308 .

[0045] In this implementation, see Figure 1 、 Figure 2 and Figure 8 The slag discharge pipe 305 is arranged below the protrusion 310. The slag discharge pipe 305 is arranged on the rotating ring 109 and protrudes out of the rotating ring 109. In this way, the discharge of the filtered matter after the outer side of the filter disc 104 is drained is convenient, and the discharged filtered matter flows away along the water source.

[0046] The working principle of the present invention is as follows: when the present invention is used, the device is set in the channel. At this time, a water pump for drip irrigation is set on the channel dam. The water intake pipe of the water pump extends from the water intake 112 into the water tank 101. At the same time, the top of the water diversion pipe 113 is connected with the water outlet branch separated from the channel water pump through a pipeline. When in use, the flowing water source flows into the water tank 101 and is pumped away by the water pump on the channel dam for drip irrigation. When flowing through the water tank 101, the flowing water source is first coarsely filtered through the water trough 106 on the conical shield 107, and then finely filtered through the filter disc 104 to ensure that the water source is free of impurities during drip irrigation and avoid clogging the drip irrigation nozzle.

[0047] On the basis of the above, when the device is placed, the conical shield 107 is facing the direction of the channel water source. When in use, the flowing water source drives the paddle blade 303 through impact to realize the rotation of the paddle shaft 301, and the paddle shaft 301 drives the backwash nozzle 203 on the branch pipe 202 to rotate through the auxiliary cylinder 304. Through this power conversion, the backwash nozzle 203 is used to backwash the filter disc 104, avoiding clogging of the outside of the filter disc 104 and affecting the filtering effect. At the same time, the rotation of the water flow drives the paddle assembly 300 to drive the toggle arm 302 to rotate on the outside of the conical shield 107. Since the conical shield 107 is set to be conical and the conical shield 107 plays a coarse filtering role, the coarse matter filtered on the outside of the conical shield 107 passes through The movement of the toggle arm 302 and the conical structure of the conical shield 107, combined with the impact of the water body on the outside of the conical shield 107, allow the filtered coarse matter to flow along the water source and the conical structure of the conical shield 107 directly backward, avoiding blockage of the front end of the conical shield 107. At the same time, the driving blade 303 is arranged in the inner conical groove 108 of the conical shield 107, and the conical shield 107 also plays a role in protecting the driving blade 303. At the same time, the front-larger and back-smaller structure of the inner conical groove 108 strengthens the impact force of the water source on the driving blade 303. In actual use, the water pump on the channel dam further accelerates the flow rate of the water source, thereby further ensuring the power conversion of the driving blade 303.

[0048] On the basis of the above, when the driven flushing arm assembly 200 and the water flow driven paddle assembly 300 rotate with the impact of the water source, the backwash nozzle 203 on the driven flushing arm assembly 200 forms a circular backwash on the filter disc 104, realizing the backwashing and blocking prevention of the entire disc body of the filter disc 104. While the driven flushing arm assembly 200 is circumferentially backwashing and blocking prevention, the present invention is provided with a second conical gear ring 204 on the branch pipe 202, and a first conical gear ring 103 is provided on the filter disc 104. The second conical gear ring 204 on the branch pipe 202 of the present invention is provided with a first conical gear ring 103. 04 and the first conical gear ring 103 on the filter disc 104 are respectively located on both sides of the reversing bevel gear 111, and the second conical gear ring 204 and the first conical gear ring 103 are respectively engaged with both sides of the reversing bevel gear 111. When the backwash nozzle 203 on the branch pipe 202 rotates in a circular motion for backwashing and anti-blocking, the filter disc 104 rotates synchronously through the conversion of the above-mentioned meshing relationship, and the direction of rotation of the filter disc 104 is opposite to the direction of rotation of the backwash nozzle 203 on the branch pipe 202, that is, when the backwash nozzle 203 rotates clockwise, the filter disc 104 rotates. Synchronous counterclockwise rotation, the present invention sets the filter disc 104 into a rotating structure. Compared with the traditional fixed structure, when the filter disc 104 rotates in the opposite direction, on the one hand, the filter disc 104 is immersed in the water source, and the top and bottom positions of the disc body are interchanged. Because in actual use, the top of the filter disc 104 is not completely immersed in water, through this transposition filtering structure, the top and bottom of the filter disc 104 are interchanged, and the idle disc body at the top is interchanged with the disc body used for filtering at the bottom, sharing the filtering pressure of the filter disc at the same position. At the same time, the present invention The filter disc 104 is configured to rotate in the opposite direction to the backwash nozzle 203. In this way, the backwash effect of the backwash nozzle 203 on the filter disc 104 is ensured. Because if the filter disc 104 is rotated in the same direction as the backwash nozzle 203, if there is no speed difference or the speed difference is very small between the backwash nozzle 203 and the filter disc 104, this will cause the backwash nozzle 203 to continue to backwash the same position of the filter disc 104 or the cycle of backwashing the entire disc body will be long. The relative reversal structure of the present invention completely avoids the above-mentioned problem.

[0049] On the basis of the above, the outer side of the filter disc 104 is used for water to enter, forming an inward water flow direction, but the backwash nozzle 203 is arranged on the inner side of the filter disc 104. During backwashing, the backwash nozzle 203 sprays water in the opposite direction of the water flow direction. If there is a water pressure confrontation between them during backwashing, it will cause the backwash nozzle 203 to have a poor backwashing filtration effect on the filter disc 104. The present invention provides an auxiliary cylinder 304 at the position of the filter disc 104 relative to the backwash nozzle 203. When the driven flushing arm assembly 200 and the water flow driven paddle assembly 300 rotate in the nacelle assembly 100, a backwash structure is formed on the inner side of the filter disc 104. Through the action of the auxiliary cylinder 304, an auxiliary extraction structure is formed on the outer side of the filter disc 104, that is, pressurized flushing is applied on the inner side of the filter disc 104, and extraction is guided on the outer side of the filter disc 104. This completely avoids the water pressure confrontation during backwashing of the filter disc 104, thereby ensuring effective backwashing filtration of the filter disc 104.

[0050] The specific working principle of the water pressure confrontation during the above-mentioned backwashing is that when the driving blade 303 drives the auxiliary cylinder 304 on the paddle shaft 301 to rotate, the traveling bevel gear 309 on the top of the auxiliary cylinder 304 circumferentially meshes and travels on the guide rail bevel gear 105. At this time, the inner shaft rod 308 forms a self-rotating structure. When the inner shaft rod 308 rotates in the auxiliary cylinder 304, the inner shaft rod 308 will drive multiple linkage arc plates 311 to rotate in the auxiliary cylinder 304, and a pumping chamber 313 is formed between the two linkage arc plates 311. When the linkage arc plate 311 rotates to the protrusion 310, the protruding structure of the protrusion 310 forms an inward thrust on the linkage arc plate 311, so that the water between the two linkage arc plates 311 is discharged through the slag discharge pipe 305. When the arc plate 311 passes over the protrusion 310 and rotates to the air guide cover 306, the protrusion 310 stops squeezing the linked arc plate 311, so that the space of the pumping chamber 313 between the two linked arc plates 311 becomes larger to form a pumping structure. In this way, when the traveling bevel gear 309 engages and travels on the guide rail bevel gear 105, a pumping structure is formed in the auxiliary cylinder 304. Since the auxiliary cylinder 304 and the backwash nozzle 203 are respectively arranged on both sides of the filter disc 104, the outward impact backwashing of the backwash nozzle 203 and the outward guided pumping of the auxiliary cylinder 304 can ensure the anti-blocking and filtering backwashing of the filter disc 104, avoid the formation of water pressure confrontation during backwashing, thereby ensuring the continuous filtration of the water source by the filter disc 104.

[0051] The present invention improves the filter disc 104 into a rotating structure and improves the backwash nozzle 203. At the same time, an innovative design of synchronous reversal is set between the backwash nozzle 203 and the filter disc 104. In combination with the backwash filtration anti-blocking design on one side of the filter disc 104 and the water pressure resistance design during backwashing on the other side, the filtering effect of the filter disc 104 on the water source is maximized. At the same time, the device of the present invention is integrated with the channel and the pump station to achieve coordinated use between the present invention, the channel and the pump station.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
