Description

Technical Field

[0001] The invention relates to the technical field of cleaning an inner flow inlet grille, and in particular to a V-shaped angle flushing device for a W-shaped inner flow inlet grille. Background Art

[0002] The W-type internal inlet grille is an advanced and efficient water treatment equipment, mainly used to intercept various solid debris in the water, such as branches, leaves, fibers and plastic garbage. Through its unique design and working principle, the W-type internal inlet grille can operate continuously and stably, and effectively separate impurities in sewage. It has the characteristics of compact structure, easy installation and reliable operation. It can adapt to sewage with different flow rates and water qualities, and plays an important role in many fields such as sewage treatment plants, industrial wastewater treatment facilities, and municipal drainage systems.

[0003] Liquid flows out from the many gaps of the W-shaped inner flow inlet grille, and dirty solid impurities are left on the surface of the W-shaped inner flow inlet grille and are transmitted along with the rotation of the W-shaped inner flow inlet grille. Since these dirt contains a large number of solid impurities, it is very easy to get stuck between the gaps of the W-shaped inner flow inlet grille. Although a high-pressure spray gun is provided for special flushing treatment, the flushing effect of the high-pressure spray gun in actual conditions is not obvious, and it is difficult to effectively clean up the solid impurities stuck in the gaps, resulting in a significant reduction in the subsequent sewage treatment capacity of the W-shaped inner flow inlet grille.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0009] Furthermore, a fixed limiting plate is sleeved on the outer side of the circumference of the guide slide rod located in the inner section of the guide cylinder, and a compression spring is sleeved on the outer side of the guide slide rod. The two ends of the compression spring are respectively fixedly connected to the limiting plate and the bottom of the inner wall of the guide cylinder.

[0010] Furthermore, a guide flushing assembly is provided on the top of the support frame 2, and the inner side wall of the support seat 3 is obliquely fixedly connected with a guide rail. The guide flushing assembly includes a guide slide and two rotating shafts, and the two ends of the rotating shaft are movably connected to the side wall of the support seat 3 through bearings, and spur gears are fixedly sleeved on the outer side of the circumference of the two ends of the rotating shaft.

[0011] Furthermore, the guide flushing assembly also includes a pushing frame, and both sides of the side walls of the pushing frame are fixedly connected with guide slides, the top and bottom of the guide slides are fixedly connected with tooth plates meshing with spur gears, and the sides of the tooth plates are fixedly connected with slides, and the slides are slidably connected in the corresponding guide rails.

[0012] Furthermore, the side wall of the support seat 2 is movably connected to a turntable via a bearing, the side wall of the turntable is rotatably connected to a connecting rod, one end of the connecting rod is rotatably connected to a connecting rod fixedly connected to the side wall of the push frame, and multiple groups of nozzles are fixedly installed at equal intervals on the side wall of the rotating shaft.

[0015] The present invention also provides a flushing method for a V-shaped angle flushing device for a W-shaped inner inlet grille, comprising the following steps: Step 1: Motor 2 drives the turntable to rotate, so that the push frame pushes the slide bar set on the side wall of the toothed plate to slide back and forth in a directional and stable manner in the guide rail. The spur gear deflects back and forth under the action of the toothed plate, and drives the rotating shaft and the nozzle to deflect, so that the nozzle changes direction, so that the water sprayed by the nozzle passes through the gap of the W-shaped inner inlet grille and preliminarily cleans the impurities attached to the non-gaps of the W-shaped inner inlet grille; Step 2: The W-shaped inner inlet grille that has been initially flushed continues to be conveyed.

During the rotation process, the rotating arm pulls the guide slide bar through the swing rod to slide upward in the guide cylinder. When the active block rotates to the highest point and continues to rotate, the active block is separated from the contact with the driving rod under the action of the vibration block's own gravity, so that the vibration block drives the guide slide bar to slide by itself and reciprocately vibrate the outer surface of the W-shaped inner inlet grille, and a plurality of groups of small protrusions are arranged at the bottom of the vibration block, so as to fully hit the V-shaped groove in the W-shaped inner inlet grille, and effectively separate the solid impurities stuck in the gap of the W-shaped inner inlet grille; Step 3: The W-shaped inner inlet grille that has been subjected to the shock treatment is continuously conveyed and is then cleaned a second time by the guide flushing assembly, thereby further improving the cleaning capability of the impurities attached to the surface of the W-shaped inner inlet grille.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is in use, the motor drives the rotating rod to rotate, causing the rotating arm to rotate under the action of the active block and the driving rod. When the active block rotates to the highest point and continues to rotate, the active block is separated from the contact with the driving rod under the action of the vibration block's own gravity, so that the vibration block reciprocates and vibrates the outer surface of the W-shaped inner inlet grille. At the same time, the protrusions arranged at the bottom of the vibration block fully hit the V-shaped grooves in the W-shaped inner inlet grille, thereby effectively separating the solid impurities stuck in the gaps of the W-shaped inner inlet grille.

[0017] 2. When the present invention is in use, the push frame pushes the slide bar provided on the side wall of the toothed plate to slide back and forth in a directional and stable manner in the guide rail. With the cooperation between the toothed plate and the spur gear, the rotating shaft drives the nozzle to deflect back and forth, causing the nozzle to change direction, thereby allowing the water sprayed from the nozzle to pass through the gaps in the W-shaped inner inlet grille and effectively rinse and clean the impurities attached to the non-gaps in the W-shaped inner inlet grille.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Figure 1-Figure 3 As shown, a V-shaped angle flushing device for a W-shaped inner inlet grille comprises a sewage tank 1, a W-shaped inner inlet grille 2 is arranged above the sewage tank 1, the W-shaped inner inlet grille 2 has two V-shaped angles, and the inner inlet grille is arranged into a W shape, so as to effectively improve the sewage treatment capacity, a support frame 1 301 and a support frame 2 302 are fixedly connected above the sewage tank 1, a vertical plate 4 is symmetrically fixedly connected to the bottom of the support frame 1 301, a vibrating material assembly 5 is arranged on one side of the vertical plate 4, an upper connecting frame and a lower connecting frame are fixedly connected to the side wall of the vertical plate 4 by bolts, a support seat 1 6 is symmetrically fixedly connected to the bottom of the upper connecting frame, a support seat 2 701 and two support seats 3 702 are fixedly connected to the top of the support frame 2 302, and a guide flushing assembly 10 is arranged on the top of the support frame 2 302; The vibrating material assembly 5 includes a rotating rod 501, a rotating arm 502 and a driving ring 503. The rotating arm 502 and the driving ring 503 are equidistantly arranged on the outer side of the circumference of the rotating rod 501. The side wall of the driving ring 503 is fixedly connected to the driving rod 504. The middle part of the side wall of the rotating arm 502 is fixedly connected to an active block 505 that cooperates with the driving rod 504. The bottom of the side wall of the rotating arm 502 is rotatably connected to a swing rod 506. The outer side wall of the support seat 6 is fixedly installed with a motor 1 for driving the rotating rod 501.

[0022] The vibration material assembly 5 also includes a guide cylinder 507, which is fixedly connected to the side wall of the lower connecting frame, and a guide slide bar 508 is slidably connected inside the guide cylinder 507. The bottom end of the swing rod 506 is rotatably connected to the top end of the guide slide bar 508, and the bottom end of the guide slide bar 508 is fixedly connected to a vibration block 509. The inner wall of the circumference of the rotating arm 502 is movably connected to the outer wall of the circumference of the rotating rod 501 through a bearing, and the inner wall of the circumference of the driving ring 503 is fixedly connected to the outer wall of the circumference of the rotating rod 501. The guide slide bar 508 is located on the outer side of the circumference of the inner section of the guide cylinder 507, and a fixed limiting plate 8 is sleeved on the outer side of the guide slide bar 508. A compression spring 9 is sleeved on the outer side of the guide slide bar 508, and the two ends of the compression spring 9 are respectively fixedly connected to the limiting plate 8 and the bottom of the inner wall of the guide cylinder 507.

[0023] In the specific setting, the W-shaped inner flow inlet grille 2 is rotated at a uniform speed to filter the dirt in the sewage tank 1, so that the liquid flows out from the gap of the W-shaped inner flow inlet grille 2, while the dirt solid impurities are left on the surface of the W-shaped inner flow inlet grille 2 and are transmitted along the W-shaped inner flow inlet grille 2. Since the dirt contains a large amount of solid impurities, it is easy to get stuck in the gap of the W-shaped inner flow inlet grille 2. Although it is flushed with a high-pressure spray gun, the flushing effect of the high-pressure spray gun is not ideal. Therefore, a vibrating material component 5 is arranged on the outside of the W-shaped inner flow inlet grille 2; The motor 1 drives the rotating rod 501 to rotate, and the rotating rod 501 drives the driving ring 503 to rotate synchronously during the rotation process. The driving ring 503 drives the driving rod 504 to rotate synchronously during the rotation process. When the driving rod 504 rotates one circle, it will contact the active block 505. The active block 505 rotates under the action of the driving rod 504, and then drives the rotating arm 502 to rotate. During the rotation process, the rotating arm 502 pulls the guide slide bar 508 through the swing rod 506 to slide upward in the guide cylinder 507. Figure 1 As shown, adjacent guide slide bars 508 are fixedly connected by short bars, and a guide cylinder 507 is additionally provided on the outer side of a guide slide bar 508 for stable directional sliding of the guide slide bar 508. When the active block 505 rotates to the highest point and continues to rotate, the active block 505 is separated from the contact with the driving rod 504 under the action of the gravity of the vibration block 509, so that the vibration block 509 drives the guide slide bar 508 to slide by itself. like Figure 2 As shown, the guide slide bar 508 is located at the outer side of the circumference of the inner end of the guide cylinder 507 and a fixed limit plate 8 is sleeved. The vibration block 509 reciprocates and vibrates the outer surface of the W-shaped inner inlet grille 2 under the action of the guide slide bar 508, the limit plate 8 and the compression spring 9, and a large number of protrusions with very small diameters are arranged at the bottom of the vibration block 509. During the transmission process of the W-shaped inner inlet grille 2, a considerable part of the protrusions will enter the gap of the W-shaped inner inlet grille 2. Figure 1 As shown, the two groups of vibration blocks 509 are arranged at an angle, so that the V-shaped grooves in the W-shaped inner inlet grille 2 can be fully struck, thereby effectively removing the solid impurities stuck in the gaps of the W-shaped inner inlet grille 2.

[0024] Embodiment 2: Figure 3-Figure 6 As shown, the sewage also contains a large amount of sludge and other solid waste. The traditional high-pressure spray gun can only spray the impurities exposed in the gaps of the W-shaped inner inlet grille 2, while the impurities attached to the W-shaped inner inlet grille 2 without gaps cannot be effectively cleaned. To solve this problem, the specific improvements are as follows: The inner side wall of the support seat 3 702 is tilted and fixedly connected with a guide rail 11, and the guide flushing assembly 10 includes a guide slide 101 and two rotating shafts 102. The two ends of the rotating shaft 102 are movably connected to the side wall of the support seat 3 702 through bearings. The outer sides of the circumference of the two ends of the rotating shaft 102 are sleeved and fixed with spur gears 103. The guide flushing assembly 10 also includes a push frame 104. The two sides of the side wall of the push frame 104 are fixedly connected with the guide slide 101. The top and bottom of the guide slide 101 are fixedly connected with tooth plates 106 meshing with the spur gears 103. The side of the tooth plate 106 is fixedly connected with a slide bar 12, and the slide bar 12 is slidably connected In the corresponding guide rail 11, the side wall of the support seat 2 701 is movably connected to the turntable 107 through a bearing, and the side wall of the turntable 107 is rotatably connected to the connecting rod 108, one end of the connecting rod 108 is rotatably connected to the connecting rod fixedly connected to the side wall of the push frame 104, and a plurality of groups of nozzles 105 are fixedly installed at equal intervals on the side wall of the rotating shaft 102, and a motor 2 for driving the turntable 107 to rotate is fixedly installed on the side wall of the support seat 2 701, and a guide frame 13 is arranged on the inner side of the W-shaped inner inlet grille 2, and the guide frame 13 is used to transport the cleaned solid waste, and one end of the nozzle 105 is connected to an external mechanism with a water supply function through a conduit.

[0025] During the specific setting, the second motor drives the turntable 107 to rotate, and the turntable 107 drives the push frame 104 to move through the connecting rod 108 and the connecting rod during the rotation process, and the push frame 104 pushes the slide bar 12 set on the side wall of the tooth plate 106 to perform a directional and stable reciprocating slide in the guide rail 11. The tooth plate 106 drives the bottom and top spur gears 103 to reciprocate during the sliding process, and the spur gear 103 drives the rotating shaft 102 to reciprocate during the reciprocating deflection process. The rotating shaft 102 drives the nozzle 105 to deflect during the reciprocating deflection process, prompting the nozzle 105 to change direction, so that the water sprayed by the nozzle 105 passes through the gaps in the W-shaped inner inlet grille 2 and effectively washes and cleans the impurities attached to the non-gaps in the W-shaped inner inlet grille 2; Combining Example 1 with Example 2, it can be known that guide flushing components 10 are arranged on both sides of the support frame 1 301, the first group of guide flushing components 10 performs preliminary cleaning of the W-shaped inner flow inlet grille 2, and the second group of guide flushing components 10 performs secondary cleaning of the W-shaped inner flow inlet grille 2, and the multiple groups of nozzles 105 located at the top and bottom of the tooth plate 106 synchronously perform reciprocating deflection water spraying, thereby cleaning the solid impurities attached to the surface of the W-shaped inner flow inlet grille 2, and at the same time, in conjunction with the vibration material component 5, the vibration block 509 hits the W-shaped inner flow inlet grille 2, which can not only effectively remove impurities stuck in the gaps of the W-shaped inner flow inlet grille 2, but also use vibration and cooperate with the nozzle 105 to spray water with high pressure, thereby improving the cleaning ability of impurities attached to the surface of the W-shaped inner flow inlet grille 2.
