Description

Technical Field

[0001] This utility model relates to the field of fiberglass storage tank technology, and in particular to a fiberglass storage tank for rapid sewage discharge. Background Technology

[0002] Currently, the structural design of most wastewater storage tanks fails to effectively address the issue of residual waste liquid inside, making manual or mechanical cleaning a necessary remedial measure. This reliance on external intervention is not only inefficient but also increases maintenance costs. There is an urgent need to optimize the wastewater discharge structure of storage tanks to achieve autonomous and efficient wastewater discharge, thereby reducing the operational burden on enterprises.

[0003] A search revealed patent number CN219258353U, which discloses a vertical storage tank sewage discharge structure, comprising: a tank body with a conical bottom; an opening located in the middle of the tank bottom; an elbow with its first end connected to the opening; a sewage pipe with its first end connected to the second end of the elbow; the second end of the sewage pipe extending out of the tank body; the sewage pipe having an inclination angle; a sewage outlet located on the second end of the sewage pipe; and a guide plate located on the tank bottom, welded to the tank bottom. This improves the sewage discharge capacity of the storage tank, saves the cost of manual or mechanical cleaning of the tank's sludge and oil, and extends the service life of the storage tank. However, this technical solution relies on a single conical bottom and a 3° inclination sewage pipe, which easily leaves waste liquid residue. This may lead to frequent maintenance due to residue accumulation, affecting the equipment's lifespan. It is only suitable for low-viscosity waste liquids, and its sewage discharge effect is poor for high-viscosity or solid-containing liquids. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fiberglass storage tank for rapid sewage discharge, which overcomes the defects of poor sewage discharge effect and reduced equipment lifespan of existing tanks; and achieves the purpose of good sewage discharge effect and extended equipment lifespan.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a fiberglass storage tank for rapid sewage discharge, including a tank body, a flow guiding device at the bottom of the tank body, the flow guiding device including a bottom plate, the bottom plate adopting a truncated cylindrical structure, the upper surface of the bottom plate being an inclined plane, and an air outlet on the tank body at the lowest point of the upper surface of the bottom plate.

[0006] Furthermore, two guide plates are symmetrically arranged on the bottom plate. The two guide plates are fixedly installed along the tank body, and the two guide plates and the bottom plate form a V-shaped guide groove.

[0007] Furthermore, the angle between the upper plane of the base plate and the horizontal plane is 5°-10°.

[0008] Furthermore, the included angle between the two deflectors is 30°-60°.

[0009] Furthermore, the cross-section of the baffle is triangular, and its height gradually decreases along the direction of waste liquid flow. The vent is located on the tank between the lowest points of the two baffles.

[0010] Furthermore, the upper part of the tank is also equipped with an overflow port to prevent the liquid level from exceeding the designed maximum working liquid level. The top of the tank is equipped with a first manhole, a liquid inlet, and a vent. The first manhole is used for internal inspection and maintenance, and the vent is used to maintain the air pressure balance inside the tank.

[0011] Furthermore, a second manhole is provided at the bottom of the tank for cleaning and inspecting bottom sediments, and for inspecting and maintaining the tank bottom.

[0012] Furthermore, the tank body, bottom plate, and baffle plate are made of fiberglass.

[0013] Furthermore, the diameter of the vent outlet is DN50-DN200.

[0014] Furthermore, the tank is cylindrical.

[0015] This utility model adopts the above technical solution and has the following advantages compared with the prior art: the drain port, combined with the inclined base plate, uses gravity to quickly discharge most of the waste liquid, shortening the sewage discharge time. The guide channel guides the remaining small amount of waste liquid to slowly collect to the drain port, reducing the amount of residue and avoiding the residue problem caused by poor liquid flow in traditional structures. It also prevents corrosion caused by long-term sludge accumulation and has a good sewage discharge effect. The guide channel and the drain port work together to reduce the need for manual cleaning. It is especially suitable for waste liquids containing particles, high viscosity, or easy to settle, avoiding the problem of frequent maintenance due to residue accumulation in traditional single drain ports and extending the service life of the equipment.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Examples, such as Figure 1-3 As shown, a fiberglass storage tank for rapid sewage discharge includes a tank body 1. The bottom of the tank body 1 is provided with a flow guiding device 9, which includes a bottom plate 10. In this example, the tank body 1 is cylindrical, and the bottom plate 10 adopts a truncated cylindrical structure. The upper surface of the bottom plate 10 is an inclined plane, and the angle between the upper surface and the horizontal plane is 5°-10°. In this example, the angle is 10°.

[0022] The tank body 1 at the lowest point of the upper plane of the bottom plate 10 is provided with an air vent 7. Waste liquid is collected by the diversion device 9 and discharged through the air vent 7.

[0023] Two guide plates 11 are symmetrically arranged on the bottom plate 10. The two guide plates 11 are fixedly arranged along the tank body 1. The two guide plates 11 and the bottom plate 10 form a V-shaped guide channel 8. The included angle between the two guide plates 11 is 30°-60°, which is 60° in this example. The cross-section of the guide plate 11 is triangular, and its cross-sectional height gradually decreases along the direction of waste liquid flow. The drain port 7 is set on the tank body 1 between the lowest points of the two guide plates 11, which can effectively guide the waste liquid to the drain port 7 for centralized discharge.

[0024] The tank body 1, bottom plate 10 and guide plate 11 are made of fiberglass.

[0025] The upper part of the tank body 1 is also provided with an overflow port 6, which is used to prevent the liquid level from exceeding the designed maximum working liquid level. The top of the tank body 1 is provided with a first manhole 2, a liquid inlet 4, and a vent 5. The first manhole 2 is used for internal inspection and maintenance. The vent 5 is used to maintain the air pressure balance inside the tank body 1.

[0026] A second manhole 3 is also provided at the bottom of the tank body 1 for cleaning and inspecting bottom sediments, and for inspecting and maintaining the tank bottom.

[0027] The diameter of the vent 7 is selected from DN50 to DN200 flanges according to the tank volume and specifications.

[0028] Working principle: When sewage needs to be discharged, the drain port 7 is opened. The inclined base plate 10 uses gravity to allow the waste liquid to flow naturally to the lowest point and collect, which is the direction of the drain port 7. As a result, most of the waste liquid is discharged quickly. A small amount of residual waste liquid is slowly guided to the drain port 7 through the guide channel 8 to reduce retention and ensure complete drainage.

[0029] The drain port 7, in conjunction with the inclined base plate 10, utilizes gravity to quickly discharge most of the waste liquid, shortening the sewage discharge time. The guide channel 8 guides the remaining small amount of waste liquid to slowly collect at the drain port 7, reducing the amount of residue and avoiding the residue problems caused by poor liquid flow in traditional structures. It also prevents long-term sludge accumulation from causing corrosion, resulting in good sewage discharge. The guide channel 8 and the drain port 7 work together to reduce the need for manual cleaning, making it especially suitable for waste liquids containing particles, high viscosity, or easy sedimentation. This avoids the problem of frequent maintenance due to residue accumulation in traditional single drain ports, extending the equipment's lifespan.
