Description

Technical Field

[0001] This utility model relates to the field of sewage discharge technology, and in particular to an auxiliary device for sewage discharge in a land-based circular pool. Background Technology

[0002] In the aquaculture process of land-based circular pond facilities, due to the accumulation of fish feces, uneaten feed and floating debris in the water, it is necessary to regularly discharge sewage from the pond. When discharging sewage, the drain valve at the bottom of the pond is opened to allow the sewage to be discharged from the drain outlet. However, in existing facilities, the drain outlet is mostly a grid-shaped straight drain outlet, which results in low drainage efficiency, limited discharge area, and poor discharge effect. Therefore, this invention proposes a sewage discharge auxiliary device for land-based circular ponds to solve the above problems. Utility Model Content

[0003] The present invention aims to provide a wastewater discharge auxiliary device for land-based circular pools to solve the problems of low drainage efficiency, limited discharge area, and poor discharge effect of existing grid-shaped drainage outlets.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wastewater discharge auxiliary device for a land-based circular pool includes a resistance block, which is circular in structure. Several fan blades are connected to the side of the resistance block. The fan blades are inclined at an angle of 30 degrees and form a spiral structure. Fixed steel rings are connected to the outer side of the fan blades.

[0006] Furthermore, the diameter of the device is designed according to the size of the land-based circular pool. For example, if the diameter of the land-based circular pool is 21 meters, the overall diameter of the device is 1.6 meters, and the diameter of the resistance block is 0.6 meters.

[0007] Furthermore, the fan blades are made of 0.3-0.5mm thick steel plates.

[0008] Furthermore, the fan blade is connected to a second steel ring, which is located in the middle of the fan blade.

[0009] The principle and beneficial effects of this technical solution: The device of this utility model has a spiral-shaped base plate. During sewage discharge, it utilizes the strong pressure of the water itself to create an impact force, which, through the spiral blades, forms a fan-shaped jet of water below, which can enhance the flushing of sediments. Its sewage discharge range can be expanded to a perimeter of 1 meter, resulting in higher sewage discharge efficiency compared to traditional grid-shaped drain outlets. The centrifugal force of traditional grid-shaped water flow is only near the sewage outlet, resulting in a small water flow, a small sewage discharge range, and low cleaning efficiency.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0014] like Figures 1-2 The device shown is a wastewater discharge auxiliary device for a land-based circular pool. The main body of the device has a diameter of 1.6m and includes a resistance block 1 with a diameter of 0.6m. The resistance block 1 is connected to several fan blades 2 with an inclination angle of 30 degrees. The fan blades 2 are made of 0.3-0.5mm thick steel plates. The several fan blades 2 form a spiral structure. The outer side of the several fan blades 2 is connected to a fixing steel ring 3, and the middle part of the fan blades 2 is connected to a second steel ring 4.

[0015] The specific implementation process is as follows: In a land-based circular pool with a diameter of 21 meters, the daily water exchange volume is 40-50 cm high, and the total water volume of the pool is 1000 cubic meters, resulting in relatively high water pressure. During sewage discharge, micro-flow pipes are normally open within the pool. These micro-flow pipes generate centrifugal force, causing uneaten feed and feces to be discharged through them. Floating suspended matter is concentrated at the bottom of the pool. Combined with the device of this invention located at the bottom, opening the main sewage valve at the bottom of the pool for 10-20 minutes can completely drain the waste. The cleaning rate is 70% higher than that of traditional grid-type drainage, eliminating the need for manual cleaning.

[0016] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solution of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
