Mechanism for quickly removing sediment from breeding ponds

technical field

The invention relates to the field of aquaculture pond building structures or equipment, in particular to a mechanism for quickly removing sediment from aquaculture ponds.

Background technique

At present, the treatment of feces and other sediments in intensive culture ponds such as eels and prawns is mainly to discharge the feces and other sediments by connecting the sewage holes at the bottom of the eel and prawns culture ponds to the outside world. In this process, a large amount of aquaculture water will be removed together, resulting in a great waste of water resources.

Contents of the invention

The object of the present invention is to provide a mechanism for quickly removing sediments in aquaculture ponds, which can provide a buffer space for the discharge of excrement and other sediments in aquaculture ponds, concentrate and concentrate the sediments such as feces, and realize the rapid discharge of sediments such as feces and The recycling of aquaculture water greatly reduces the discharge of pond water, achieving the goals of water saving, emission reduction, energy saving and consumption reduction.

Detailed ways

The present invention is described in detail below in conjunction with accompanying drawing description:

As shown in Figures 1 and 2: a mechanism for quickly removing feces from breeding ponds, which includes a sewage accumulation tank 1 and a sewage channel 2,

The sewage channel 2 extends left and right and is arranged below the sewage collection tank 1. The sewage channel 2 is provided with a slit 3 that is consistent with the extension direction of the sewage channel 2 and communicates with the bottom of the sewage collection tank 1. One end of the sewage channel 2 (Fig. 1 The left end of the middle) extends to the outside to form the sewage outlet 4;

The bottom surface of the sewage pool 1 is a slope 11 inclined from the side to the gap 3 . Generally speaking, the sewage channel 2 is located in the middle of the bottom of the sewage collection tank 1, so the bottom surface section of the sewage collection tank 1 is in a "V" shape.

A channel 5 communicating with the bottom of the breeding pond 7 is also provided in the bottom of the sewage collecting tank 1 .

The sewage discharge port 4 of the sewage discharge channel 2 is provided with a switch structure for controlling whether the sewage discharge channel 2 is discharged. The switch structure here can be a water valve (electric or manual) or directly be an intubation tube.

The caliber of the sewage channel 2 is constant from left to right, and the caliber of the sewage channel 2 may be gradually reduced from left to right.

The opening of the bottom channel 5 (connected with the sewage outlet at the bottom of the culture pond) of the sewage accumulation tank 1 is close to the side of the sewage channel 2 . . This can ensure that a large amount of feces and other sediments are close to the outlet of the sewage channel 2, facilitating the aggregation and precipitation (concentration) of feces and other sediments. Channel 5 can be provided with a built-in valve or a plug-in outlet at the outlet of channel 5 to achieve a "stop flow" design.

It also includes water lifting equipment, which is arranged on the other side of the sewage accumulation tank 1 away from the sewage channel 2, and is used to divert the clean water in the sewage accumulation tank to the culture pond 7. The water-lifting device here can be a water pump with a drainage pipe, and can also be a start-up water-lifting device.

The width of the gap 3 is suitable for discharging dirt such as feces, and is generally above 2mm.

A plurality of rectangular dividing plates 6 can be arranged in the dirt accumulating tank 1 from left to right, the sides of the dividing plates are connected to the side walls of the dirt accumulating tank 1, and the bottom is connected to the slope 11 ("V" shape). When the water lifting device is installed on one side of the sewage accumulation pool 1 away from the sewage outlet 4, after the water body circulation of "cultivation pond + sewage accumulation pond" is formed, the feces and other sediments and sewage of the cultivation pond enter the sewage accumulation pond 1, due to the change of water flow Slowly can make feces and other sediments sink and fall into the sewage channel 2 to concentrate, effectively preventing the sewage containing feces and other sediments from being far away from the sewage outlet 4 of the sewage channel 2.

It works as follows:

There are two ways of using the present invention:

The first

Sewage accumulation pool 1 and culture pond 7 communicate with each other through channel 5 all the year round (certainly it is better to install retaining devices, such as valves, intubation pipes, etc.); equal. After the water-lifting device was installed at one end of the sewage collection pool 1 far away from the sewage outlet 4, the breeding pond 7 and the sewage collection pond 5 formed an internal circulation, and the excrement and other deposits in the cultivation pond 7 flowed into this mechanism; The feces and other sediments in the sink sink, because the bottom surface of the sewage collection tank 1 is a slope 11 inclined from the side to the gap 3 "V", driven by the slow water flow, it gathers at the gap 3 and falls into the sewage channel 2 medium (concentrated). After circulating in the culture pond for a period of time, feces and other sediments accumulate in the sewage channel 2 (more accumulation); the sewage outlet 4 is connected to the sewage channel 2, and since the sewage channel 2 is at the lowest position, when the sewage outlet 4 is opened, a large amount of concentrated , feces and other sediments accumulated in the sewage channel 2 can be quickly discharged. In this way, during the breeding process, after a period of "internal circulation" interval, the sediments such as feces in the breeding pond 7 are "transferred" to the sewage accumulation pond 1 in time, and then quickly discharged out of the pond through the sewage channel 2 and the sewage outlet 4, thereby achieving Significantly reduce drainage without affecting the function of breeding animals.

the second

Passage 5 is in a closed state on weekdays, that is, the sewage accumulation pool 1 and the culture pond 7 are not connected to each other; when in use, the two are connected, and a large amount of breeding water and feces in the culture pond 7 enter the sewage accumulation pond 1 until the liquid levels of the two are even ; Then close the channel 5 and wait for the feces to settle into the sewage channel; when the precipitation is completed, control the sewage channel 2 to discharge the feces inside and stop the sewage. Return the remaining aquaculture water in the sewage accumulation pond 1 to the aquaculture pond through a water pump or the like. If this process can be automatically controlled, the water saving effect of the sewage discharge process will be better.

In addition, in order to better maintain the stability of the water environment in the breeding pond, hair brushes can be arranged in the pollution accumulation tank 1 to increase the implantation of microorganisms and attach more suspended particles; It only falls in the sewage accumulation tank 1, and falls into the sewage channel 2, and can be directly discharged from it, so as to reduce its impact on the water environment of the breeding pond.

Although the present invention uses specific embodiments and alternatives to illustrate and describe the present invention, it should be understood that various changes and modifications can be implemented as long as they do not depart from the spirit of the present invention. Accordingly, it should be understood that the invention is not to be limited in any sense except as by the appended claims and their equivalents.
