Description

Technical Field

[0001] This utility model relates to the field of sand filter cleaning technology, specifically to a V-shaped sand filter ultrasonic rotary spray device. Background Technology

[0002] V-type sand filters are a type of high-efficiency filtration equipment commonly used in water treatment. They are mainly used to remove suspended solids, colloids, microorganisms, and other impurities from water, improving the quality of effluent. By trapping suspended particles, colloids, algae, and other pollutants in the water through a quartz sand filter layer, the turbidity of the effluent is significantly reduced. Raw water enters evenly from the V-shaped trough and passes through the sand filter layer from top to bottom. Impurities are trapped in the pores of the filter media, while clean water is discharged from the bottom. The ultrasonic rotating spray device can remove dirt from the filter layer and restore filtration capacity. However, the existing ultrasonic rotating spray device for V-type sand filters is not efficient in rinsing, as it only rinses the filter media by spraying water from top to bottom, resulting in poor rinsing effect. Furthermore, the protective filter screen on the spray head is inconvenient to remove and install, making regular maintenance difficult. When damaged, the entire spray head needs to be replaced. In view of these problems, this case was developed through in-depth research. Utility Model Content

[0003] This utility model provides an ultrasonic rotary spray device for V-shaped sand filters, which aims to solve the problems of high efficiency and easy disassembly / reassembly of the ultrasonic rotary spray devices currently used for V-shaped sand filters.

[0004] This utility model is implemented as follows: a V-shaped sand filter ultrasonic rotary spray device includes: a sand filter body; filter media tanks assembled inside both sides of the sand filter body, a control panel installed on the outer wall of one side of the sand filter body, an ultrasonic generator installed on the outer wall of the other side of the sand filter body, and a sewage outlet provided on the inner wall of one end of the lower part of the sand filter body; ultrasonic transducers uniformly fixedly installed on the inner wall above the filter media tanks, and fixing pipes installed on the inner wall below the filter media tanks, with a first water pump connected to one end of each fixing pipe on the outer wall of the sand filter body, and branch pipes uniformly connected to one end of each fixing pipe on the outer wall; a spray mechanism movably installed at the top of the fixing pipes and branch pipes, the spray mechanism being used for spraying and impacting water; a protective filter screen uniformly installed at the top of the spray mechanism; and a disassembly and assembly mechanism connected and installed below the protective filter screen, the disassembly and assembly mechanism being used for quick disassembly and assembly of the protective filter screen, thereby facilitating maintenance.

[0005] Preferably, the spraying mechanism includes: a main nozzle movably mounted on the top of the fixed pipe and the branch pipe via a sealed bearing, and inclined nozzles are uniformly connected to the outer wall of the main nozzle.

[0006] Preferably, the outer cover installed below the main nozzle has a driven gear installed on the outer wall below the main nozzle, and a driving gear is meshed on one side of each driven gear, with a drive motor connected below each driving gear.

[0007] Preferably, the water inlet pipe is installed above the filter media tank, and the top view of the water inlet pipe is U-shaped.

[0008] Preferably, the connecting pipes are evenly connected to the top ends of both sides of the water supply pipe, and flushing heads are evenly connected to one side of the outer wall of each connecting pipe.

[0009] Preferably, the disassembly and assembly mechanism includes: a positioning ring connected below the protective filter; the top of the main nozzle and the tilting nozzle are both provided with positioning grooves that cooperate with the positioning ring; the bottom of the positioning ring and the inner wall of the positioning groove are both connected with magnetic blocks, and the magnetic poles of opposite sides of the magnetic blocks are different.

[0010] Preferably, the dampers are fixedly installed on the inner walls of both sides above the main nozzle and the inclined nozzle, and a return spring is installed on the outer wall of one end of each damper. A locking rod is connected to one end of each return spring, and a pull plate is connected to the top of each locking rod. The outer wall of each positioning ring is provided with a locking groove that cooperates with the locking rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) The ultrasonic generator is used to make multiple ultrasonic transducers on the upper layer of the filter material in the filter tank generate ultrasonic vibrations to perform ultrasonic cleaning on the upper layer of filter material. The first water pump works to pump water into the fixed pipe, and then into multiple branch pipes. The water is then sprayed out through multiple main nozzles and inclined nozzles for rinsing. The drive motor works to make the drive gear rotate. The drive gear meshes with the driven gear to make the main nozzles and inclined nozzles rotate to spray and rinse. The second water pump works to pump water into the water supply pipe. The water flowing through the water supply pipe enters multiple connecting pipes and is then sprayed out through multiple rinsing heads to rinse and remove dirt, thereby rinsing the filter material above the filter tank and making the rinsing more efficient.

[0013] (2) The protective filter screen is installed to protect the main nozzle and the tilt nozzle, and prevent them from being blocked by impurities. During installation, the pull plates on both sides are pulled outward, the return spring and the damper are squeezed and deformed, and the locking rod moves outward at the same time. Then the positioning ring under the protective filter screen is inserted into the positioning groove for positioning. The magnetic blocks are quickly magnetically attracted and fixed. After the pull plate is released, the return spring and the damper are reset, and the locking rod is locked into the locking groove. When disassembling, the pull plate is pulled outward again to make the locking rod move away from the locking groove. The protective filter screen is pulled upward with a little force to remove it, which facilitates the disassembly and assembly of the protective filter screen. Attached Figure Description

[0023] A preferred embodiment of the V-shaped sand filter ultrasonic rotary spray device provided by this utility model is, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4 The V-shaped sand filter ultrasonic rotary spray device includes: a sand filter body 8; filter media tanks 1 assembled inside both sides of the sand filter body 8, a control panel 9 installed on the outer wall of one side of the sand filter body 8, an ultrasonic generator 3 installed on the outer wall of the other side of the sand filter body 8, and a sewage outlet 13 provided on the inner wall of one end of the lower part of the sand filter body 8; ultrasonic transducers 7 uniformly fixedly installed on the inner wall above the filter media tanks 1, fixed pipes 10 installed on the inner wall below the filter media tanks 1, and a first water pump 2 connected to the outer wall of the sand filter body 8 at one end of each fixed pipe 10, and branch pipes 12 uniformly connected to the outer wall of one end of each fixed pipe 10; a spray mechanism 14 movably installed at the top of the fixed pipes 10 and the branch pipes 12, the spray mechanism 14 being used for spraying and impacting water; a protective filter screen 16 uniformly installed at the top of the spray mechanism 14; and a disassembly and assembly mechanism 17 connected and installed below the protective filter screen 16, the disassembly and assembly mechanism 17 being used for quick disassembly and assembly of the protective filter screen 16, thereby facilitating maintenance.

[0024] It should be noted that the existing V-type sand filter ultrasonic rotary spray device technology has the following drawbacks: the rinsing is not efficient, it only uses water sprayed from the top and bottom of the filter media for rinsing, the rinsing effect is poor, the protective filter screen on the spray head is inconvenient to disassemble and install, which makes regular maintenance inconvenient, and the entire spray head needs to be replaced when damaged.

[0025] In this embodiment, the ultrasonic generator 3 causes multiple ultrasonic transducers 7 on the upper layer of the filter media in the filter media tank 1 to generate ultrasonic vibrations, which ultrasonically clean the upper layer of filter media. In conjunction with the operation of the first water pump 2, water is pumped into the fixed pipe 10 and then into multiple branch pipes 12. The water is then sprayed out through multiple main nozzles 1401 and inclined nozzles 1402 for rinsing. The drive motor 1405 drives the drive gear 1404 to rotate. The drive gear 1404 meshes with the driven gear 1403, causing the main nozzles 1401 and inclined nozzles 1402 to rotate and spray, making the rinsing more efficient.

[0026] In a further preferred embodiment of the present invention, the spraying mechanism 14 includes a main nozzle 1401 movably mounted on the top of the fixed pipe 10 and the branch pipe 12 via a sealed bearing, and inclined nozzles 1402 are uniformly connected to the outer wall of the main nozzle 1401.

[0027] In this embodiment, the main nozzle 1401 and multiple inclined nozzles 1402 spray water simultaneously from multiple directions, resulting in a better spraying and rinsing effect.

A drive motor 1405 is connected to the lower side of each driving gear 1404.

[0029] In this embodiment, the drive motor 1405 is used to rotate the drive gear 1404. The drive gear 1404 meshes with the driven gear 1403, which drives the main nozzle 1401 and multiple tilting nozzles 1402 to spray by rotating.

[0030] In a further preferred embodiment of this utility model, the water inlet pipe 4 is installed above the filter media tank 1, and the top view of the water inlet pipe 4 is U-shaped.

[0032] In a further preferred embodiment of this utility model, a connecting pipe 6 is evenly connected to the top of both sides of the water supply pipe 4, and a flushing head 5 is evenly connected to one side of the outer wall of the connecting pipe 6.

[0033] In this embodiment, water flowing through the water inlet pipe 4 enters multiple connecting pipes 6, and then is sprayed out through multiple flushing heads 5 to rinse and remove dirt, thereby rinsing the area above the filter media tank 1. Example 2

[0034] Based on Example 1, a preferred embodiment of the V-shaped sand filter ultrasonic rotary spray device provided by this utility model is as follows: Figure 4 , Figure 5 and Figure 6 As shown: The disassembly and assembly mechanism 17 includes: a positioning ring 1701 connected below the protective filter 16; the top of the main nozzle 1401 and the tilting nozzle 1402 are both provided with positioning grooves 1703 that cooperate with the positioning ring 1701; the bottom of the positioning ring 1701 and the inner wall of the positioning groove 1703 are both connected with magnetic blocks 1704, and the magnetic poles of opposite sides of the magnetic blocks 1704 are different.

[0035] In this embodiment, the main nozzle 1401 and the tilt nozzle 1402 are protected by installing a protective filter screen 16 to prevent them from being blocked by impurities. During installation, the positioning ring 1701 below the protective filter screen 16 is inserted into the positioning groove 1703 for positioning, and then quickly fixed by magnetic attraction between the magnetic blocks 1704.

[0036] In a further preferred embodiment of this utility model, dampers 1706 are fixedly installed on the inner walls of both sides above the main nozzle 1401 and the inclined nozzle 1402, and a return spring 1707 is installed on the outer wall of one end of each damper 1706. A locking rod 1705 is connected to one end of each return spring 1707, and a pull plate 1708 is connected to the top of each locking rod 1705. The outer wall of the positioning ring 1701 is provided with a locking groove 1702 that cooperates with the locking rod 1705.

[0037] In this embodiment, by pulling the pull plates 1708 on both sides outward, the return spring 1707 and the damper 1706 are squeezed and deformed, and the locking rod 1705 moves away from the locking groove 1702 at the same time. Then, the protective filter 16 is installed, and the positioning ring 1701 is inserted into the positioning groove 1703 for positioning. After the pull plates 1708 are released, the return spring 1707 and the damper 1706 are reset, so that the locking rod 1705 is locked into the locking groove 1702 for fixation.

[0038] In summary, the spray mechanism 14 is used to achieve the rotating spraying of the upper layer of filter media in the filter media tank 1, which washes away the upper impurities. The sewage flows out from the middle gap and is then discharged through the sewage outlet 13. The protective filter screen 16 provides protection for the spray mechanism 14, and the disassembly and assembly mechanism 17 facilitates the disassembly and assembly of the protective filter screen 16.
