Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a glass fiber reinforced plastic sewage separation tank. Background Art

[0002] When treating sewage, it is easier to separate large particles of impurities such as silt, rust, and algae because these impurities are insoluble in water. Therefore, before treating sewage, it is necessary to separate the larger particles of impurities in the sewage.

[0003] The existing practice is usually to pass sewage into a sedimentation tank and then let it settle naturally in a static state. This sedimentation method has a low cost, but the sedimentation time is long and the sedimentation efficiency is low. Another method is to add flocculants to the sedimentation tank to speed up the precipitation of impurities. At that time, the addition of flocculants will also cause certain pollution to the water quality and increase the cost of sewage treatment. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a glass fiber reinforced plastic sewage separation tank, which can accelerate the precipitation speed of impurities in sewage.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A glass fiber reinforced plastic sewage separation tank comprises a glass fiber reinforced plastic tank body and a glass fiber reinforced plastic tank cover which covers the glass fiber reinforced plastic tank body, wherein a cylindrical cavity is arranged inside the glass fiber reinforced plastic tank body;

[0007] The glass fiber reinforced plastic tank cover is provided with a drain port connected to the inside of the cylindrical cavity, and the upper part of the glass fiber reinforced plastic tank body is provided with a water inlet connected to the inside of the cylindrical cavity, and the water inlet is tangent to the inner surface of the cylindrical cavity. When the sewage enters the cylindrical cavity from the water inlet, a vortex is formed in the cylindrical cavity along the inner surface of the cylindrical cavity;

[0008] The top of the cylindrical cavity is connected to a fixing rod, the bottom of the fixing rod is connected to a filter plate, the filter plate is located above the water inlet, and the circumference of the filter plate is in contact with the inner surface of the cylindrical cavity;

[0009] The bottom of the filter plate is rotatably connected to a rotating rod; the top of the rotating rod is fixedly connected to a brush, and the brush contacts the lower surface of the filter plate; the bottom of the rotating rod is fixedly connected to a water flow baffle;

[0010] A sewage outlet connected to the inside of the cylindrical cavity is provided at the lower part of the glass fiber reinforced plastic tank body. The sewage outlet is located below the water flow baffle and a cover is provided at the sewage outlet.

[0011] Furthermore, it also includes a booster water pump; the booster water pump is connected to the water inlet.

[0012] Furthermore, a bearing is provided at the bottom of the filter plate, and the rotating rod is connected to the bearing.

[0013] Furthermore, a partition is provided at the bottom of the cylindrical cavity, and the sewage outlet is located below the partition; a plurality of openings are provided on the partition at intervals.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The water inlet of the FRP sewage separation tank is tangent to the inner surface of the cylindrical cavity. When sewage continuously enters the cylindrical cavity from the water inlet, a vortex is formed in the cylindrical cavity along the inner surface of the cylindrical cavity. Under the centrifugal force of the vortex, impurities in the sewage fall downward along the inner wall of the cylindrical cavity to the partition plate, and fall into the lower part of the cylindrical cavity through the opening on the partition plate, thereby realizing the separation of impurities in the sewage. The sewage after the impurities are separated passes through the filter plate and the filtered sewage is continuously discharged through the drain port.

[0016] At the same time, due to the effect of swirl, the water flow baffle drives the rotating rod to rotate, and the rotating rod drives the brush to rotate, thereby brushing away the impurities attached to the lower surface of the filter plate. Moreover, the water flow baffle and the partition can make the sewage disturbance at the bottom of the cylindrical cavity tend to a static state. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] refer to Figure 1-Figure 4 This embodiment provides a FRP sewage separation tank, comprising a FRP tank body 1 and a FRP tank cover 2 covering the FRP tank body 1, wherein a cylindrical cavity 100 is provided inside the FRP tank body 1. The FRP tank body 1 and the FRP tank cover 2 are both made of FRP material, which has the advantages of acid and alkali corrosion resistance and high strength.

[0023] The FRP tank cover 2 is provided with a drain port 20 connected to the interior of the cylindrical cavity 100 .

[0024] The upper portion of the FRP tank body 1 is provided with a water inlet 10 leading to the interior of the cylindrical cavity 100. The water inlet 10 is tangent to the inner surface of the cylindrical cavity 100. When sewage enters the cylindrical cavity 100 from the water inlet 10, a vortex is formed in the cylindrical cavity 100 along the inner surface of the cylindrical cavity 100. Impurities in the sewage fall downward along the inner wall of the cylindrical cavity 100 under the centrifugal force of the vortex.

[0025] Furthermore, a booster pump 18 is connected to the water inlet 10 to control the flow rate of water pumped into the water inlet 10 , so as to form a stable vortex in the cylindrical cavity 100 .

[0026] A fixing rod 21 is connected to the top of the cylindrical cavity 100 .

[0027] The bottom of the fixing rod 21 is connected with a filter plate 11, and the filter plate 11 is fixed by the fixing rod 21. The filter plate 11 can filter impurities in sewage. In addition, the filter plate 11 is located above the water inlet 10, and the circumference of the filter plate 11 is in contact with the inner surface of the cylindrical cavity 100.

[0028] A bearing 12 is disposed at the bottom of the filter plate 11 , and a rotating rod 13 is rotatably connected to the bearing 12 .

[0029] A brush 14 is fixedly connected to the top of the rotating rod 13 , and the brush 14 contacts the lower surface of the filter plate 11 .

[0030] The bottom of the rotating rod 13 is fixedly connected with a water flow baffle 15. Due to the effect of the swirling flow, the water flow baffle 15 drives the rotating rod 13 to rotate, and the rotation of the rotating rod 13 drives the brush 14 to rotate, thereby brushing away impurities attached to the lower surface of the filter plate 11. In addition, the water flow baffle 15 can reduce the disturbance of sewage at the bottom of the cylindrical chamber 100.

[0031] The bottom of the cylindrical cavity 100 is provided with a partition 16, and a plurality of openings 161 are arranged at intervals on the partition 16. Impurities in the sewage fall into the lower part of the cylindrical cavity 100 through the openings 161 on the partition 16, so that the impurities in the sewage are separated. The partition 16 further reduces the disturbance of the sewage at the bottom of the cylindrical cavity 100 and makes it tend to be static.

[0032] A sewage outlet 17 connected to the inside of the cylindrical cavity 100 is provided at the lower part of the FRP tank body 1. The sewage outlet 17 is located below the partition 16. A cover 19 is provided at the sewage outlet 17. When impurities need to be discharged, the cover 19 is opened.

[0033] This glass fiber reinforced plastic sewage separation tank can accelerate the precipitation speed of impurities in sewage and is practical.
