technical field

The utility model relates to the field of biological research, in particular to a novel high-efficiency water system benthic animal cleaning and separation device.

Background technique

In the process of collecting and researching aquatic organisms, it is necessary to clean the sediment and separate the benthic organisms from the sediment. The traditional benthic organisms are mostly separated by vibrating screens, but the sediments are often glued together. The method of vibrating screen often has poor separation effect, and the vibrating screen is easy to cause damage to aquatic organisms due to strong vibration.

Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects.

The middle part of the bottom of the casing has a water outlet, the lower end of the water outlet is connected with a water outlet, and a valve is installed at the water outlet. .

By adopting the above technical solution, the sediment is placed at the first screen, and the shell is filled with water to the benthic organisms that have not passed the uppermost screen, and then the gas is injected into the shell from the bottom by starting the air pump, thereby Drive the flow of water, separate the mud blocks accumulated on the top layer from benthic organisms through the impact of water flow and air bubbles, accelerate the dispersion and dissolution of mud, and enable benthic organisms to adapt to their own radius under the action of gravity. After falling into different screen intervals, the air pump is turned off, so that the sediment in the water is free to settle into the shell. At this time, the activated carbon adsorbs the sediment, and the benthic animals stay in their respective screen layers according to the size of the pores, and the water is turned on. The valve is drained to collect the benthic animals required for classification, and the activated carbon can be washed and put into use again after being taken out.

Further, the casing is a cylindrical structure, the top of the casing is open, the bottom of the casing is closed, and the upper outer wall of the casing is a threaded structure;

To sum up, the utility model has the following beneficial effects:

1. The device uses four water pipes that can pass into the air as the main force application points. The device is filled with water until the benthic organisms that do not pass through the uppermost screen, and then a large amount of air is quickly introduced into the water to drive the flow of water. Operation, through the impact of water flow and bubbles, the mud blocks accumulated on the top layer are separated from the benthic organisms, which accelerates the dispersion and dissolution of the mud, and under the action of gravity, the benthic organisms can fall in different sizes according to their own radius. Compared with the vibration separation device, the device can greatly reduce the damage to benthic organisms caused by vibration, and can save electric energy.

2. A valve is installed at the end of the device, and the valve is always closed during cleaning to prevent the internal water flow from flowing out. A breathable porous fixing plate is added on the top of the installation cover, which can prevent the internal air pressure from being too large. It can also prevent benthic animals from overflowing from the top. A sealing ring is set on the outer part of each fixed ring to increase the airtight type of the device, so that the screen is not easy to fall off and prevent the water from overflowing. It is used to adsorb the sedimented sludge and impurities, speed up the separation efficiency, and can be disassembled, cleaned and reused after the operation of the machine.

3. The device can be fully automated. The outside of the machine can independently regulate the time and airflow rate of each ventilation, and select the number of ventilations and the waiting time due to the static device in between. The user can leave after setting the parameters. Just wait for the machine to complete all operations.

4. Compared with the vibration separation device, this device has higher utilization efficiency of water resources, avoids the waste of water resources caused by continuous flushing and drainage, and can also effectively avoid the hidden danger of water overflow caused by continuous water flow. The integrated automation of the device saves the user the trouble of operating the machine all the time and saves manpower.

5. After the operation of the machine is over, the valve at the bottom can be opened to remove sewage and sediment to clean the instrument.
