Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically to a fiberglass grating tank for water treatment. Background Technology

[0002] A fiberglass grating tank is a water tank or treatment facility covered with a grating panel made of fiberglass (FRP, fiber reinforced plastic). It is commonly used in sewage treatment, industrial wastewater tanks, rainwater harvesting tanks, and walkway platforms for preliminary filtration of large debris in water. Traditional grating tanks have a relatively fixed structure. When the grating mesh becomes clogged with debris, it needs to be cleaned, at which point the grating tank cannot continue to operate, severely reducing sewage treatment efficiency. In emergency situations, if not addressed promptly, it can cause serious blockages in drainage pipes, greatly increasing maintenance costs. A new type of grating tank is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a fiberglass grating tank for water treatment, comprising a tank body with several grooves along the liquid flow direction on the inner wall of the tank. A frame seat is embedded in the grooves, and a vertical plate on one side of the frame seat and the vertical channel of the grooves form a transmission chamber. The two vertical plates of the frame seat are rotatably connected to hinged columns on both sides of a flipping frame. The hinged columns extend into the transmission chamber and connect to a flipping assembly. A grating mesh is embedded in the flipping frame. When the flipping frame is in a vertical position, the chamfered bottom edge of the flipping frame is fitted with a clearance fit to the bottom plate of the frame seat. When all flipping frames are in a horizontal position, the opening of the tank body can be closed.

[0004] Furthermore, the flipping assembly includes a control lever, the body of which is rotatably connected to a vertical through hole on the side sealing block of the frame base vertical plate. A handwheel is provided at the top of the control lever, and the bottom gear of the control lever meshes with the end gear of the hinge column.

[0005] Furthermore, the two sides of the flip frame are provided with several screw holes, and the screw holes are connected to the clamps by bolts. The clamps on both sides fit against the side of the grid mesh.

[0006] Furthermore, the top surface of the vertical plate of the frame base has a threaded hole, and the threaded hole is connected to the limiting block through a hinge bolt. The bottom surface of the limiting block can be rotated to fit against the top surface of the frame base.

[0007] Furthermore, the pool body has insertion plates at both ends. A feed pipe is embedded in the insertion plate at the beginning, with the feed pipe being higher than the hinged column. A discharge pipe is embedded in the insertion plate at the end, with the discharge pipe being lower than the hinged column. A grid cover with hooks is hinged to the upper side of the discharge pipe inlet.

[0008] The beneficial effects of this utility model are as follows: This utility model allows the rotating control lever, via a handwheel, to flip the rotating frame containing the mesh screen from a vertical position to a horizontal position, thereby changing the filtration method of the bar screen tank. It can achieve both vertical layer-by-layer filtration of wastewater from the inlet pipe to the outlet pipe, and horizontal filtration of rainwater flowing into the tank. When some mesh screens become clogged, the rotating frame can be rotated for quick unblocking and cleaning. It is characterized by strong applicability and convenient operation.

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] like Figures 1 to 3 As shown, a fiberglass grating tank for water treatment includes a tank body 1. The inner wall of the tank body 1 has several grooves 101 along the liquid flow direction. A frame seat 2 is embedded in the grooves 101. A vertical plate on one side of the frame seat 2 and the vertical channel of the groove 101 form a transmission chamber 102. The two vertical plates of the frame seat 2 are rotatably connected to hinged columns 301 in the middle of both sides of a flip frame 3. A grating mesh 4 is embedded in the flip frame 3. Several screw holes are provided around both sides of the flip frame 3. The screw holes are connected to the locking blocks 6 by bolts. The locking blocks 6 on both sides fit against the sides of the grating mesh 4. The locking blocks 6 can be removed to replace the grating mesh 4.

[0017] In this embodiment, the hinge column 301 extends into the transmission chamber 102 and connects to the flipping assembly. The flipping assembly includes a control rod 5, the body of which is rotatably connected to the vertical through hole 201 on the side sealing block of the vertical plate of the frame base 2. A handwheel 501 is provided at the top of the control rod 5, and the gear at the bottom of the control rod 5 meshes with the gear at the end of the hinge column 301. When all the flipping frames 3 are in the horizontal position, the opening of the pool body 1 can be closed. When the flipping frame 3 is in the vertical position, the chamfered bottom edge of the flipping frame 3 is in clearance fit with the bottom plate of the frame base 2, and the top surface of the frame base 2 can fit against the limiting block 8. The limiting block 8 is connected to the threaded hole opened on the top surface of the vertical plate of the frame base 2 through the hinge bolt 7, and the limiting block 8 can rotate around the hinge bolt 7.

[0018] In this embodiment, the two ends of the pool body 1 are connected to the insertion plates 9. The insertion plate 9 at the beginning is embedded with the feed pipe 10, which is higher than the hinge post 301. The insertion plate 9 at the end is embedded with the discharge pipe 11, which is lower than the hinge post 301. The upper side of the inlet of the discharge pipe 11 is hinged with a grid cover 12 with a hook. When the grid cover 12 is blocked, it can be pulled up by the hook.

[0019] The working principle of this utility model is as follows:

[0020] When vertical filtration of wastewater is required, each tilting frame 3 is in a vertical position. At this time, wastewater flows into the tank 1 only from the inlet pipe 10. Floating objects in the water are filtered step by step through each layer of bar screens 4. The mesh size of each bar screen 4 can be changed as needed. The filtered wastewater is discharged from the tank 1 through the discharge pipe 11. When some bar screens 4 become clogged, turn the handwheel 501 at that location to tilt the clogged bar screen 4 to a horizontal position. At this time, the remaining bar screens 4 continue to work normally, and the operator can use a lever to clear the clogged mesh. When it is necessary to filter flooded rainwater, each tilting frame 3 is rotated to a horizontal position. At this time, the bar screens 4 close the opening of the tank 1. Rainwater and wastewater discharged from the inlet pipe 10 must be filtered through the bar screens 4 before being discharged from the tank 1 through the discharge pipe 11.

[0021] This utility model can flip the flipping frame from a vertical position to a horizontal position through the flipping component, thereby realizing different filtration methods of the bar screen pool. At the same time, it can also quickly unclog and clean when some bar screens are blocked. It has the characteristics of strong applicability and convenient operation.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
