Description

Technical Field

[0001] The utility model relates to the technical field of sampling and separation equipment, in particular to a bottom-inlet and middle-exhaust vortex sorting device. Background Art

[0002] At present, the sorting and flushing of marine benthic organisms usually requires the use of a sorting device. In the products of the prior art, the separation device includes a motor, a separation screen and other equipment. The motor is usually used to drive the rotation of the water flow to achieve the sedimentation and discharge of the sediment and the suspension sorting of the organisms. This vortex separation method not only has complex structure and equipment, increases investment costs, but also requires additional electricity consumption, resulting in a waste of resources. There is also a vortex separation device that does not use a motor for separation. It mainly sets a spiral pattern on the separation cylinder to form a vortex with the impact of a single group of water flow to achieve separation. The vortex generated by the water flow entering the separation cylinder in this way is small, and its effect on the separation and sedimentation of sediment is poor. The sediment is easily accumulated in the spiral pattern at the bottom of the cylinder, and its sorting efficiency is not ideal. For this reason, a bottom-inlet and middle-exhaust vortex sorting device is proposed. Utility Model Content

According to fluid mechanics, the suspended object moves in the direction of lower pressure, and the bottom of the vortex center is suspended. The benthic organisms move toward the center of the double-conical cylinder 1, and the hollow drain pipe 21 is arranged in the middle of the double-conical cylinder 1, and the hollow drain pipe 21 is set as an inverted truncated cone structure, which can increase the contact area with the vortex and facilitate the rapid discharge of suspended benthic organisms.

[0034] See also Figure 7 The water inlet assembly 3 is arranged on the side wall of the bottom of the double-conical cylinder 1. The water inlet assembly 3 includes a side water inlet pipe 31. The input end of the side water inlet pipe 31 is provided with a control valve 32. The control valve 32 is provided with a control handle 33. The water inlet assembly 3 is provided with a side water inlet pipe 31 to establish a connection with the water inlet pipe support frame 4. The side water inlet pipe 31 is arranged on the bottom wall plate of the double-conical cylinder 1 through the water inlet pipe support frame 4 to pour the extracted seawater into the double-conical cylinder 1. The side water inlet pipe 31 controls the seawater inflow by setting the control valve 32, thereby adjusting the input amount of the water flow in the inner cavity of the double-conical cylinder 1 and the size of the vortex.

[0035] The input direction of the side water inlet pipe 31 is set at an angle of 30 degrees counterclockwise with the central axis of the double-conical cylinder 1. The water flow input at the angle will impact the middle of the mud sample at the bottom of the barrel, which is conducive to the rapid dispersion of the mud sample. The four groups of water inlet components are evenly distributed to make the vortex in the barrel move smoothly and form a smooth impact water flow to avoid mud sample accumulation.

[0036] A limiting mounting frame 25 is provided on the right side wall of the cylinder support frame 5 corresponding to the connecting pipe 24. The connecting pipe 24 passes through the right side wall plate of the cylinder support frame 5 and is fixed on the cylinder support frame 5 through the limiting mounting frame 25 to complete the stable installation of the drainage pipe fittings.

[0037] A supporting rubber pad is provided at the top of the cylinder support frame 5, and the supporting rubber pad is provided with a connecting groove. The connecting groove is provided at the bottom of the outer end of the double-conical cylinder 1. The top of the cylinder support frame 5 establishes support for the bottom of the double-conical cylinder 1 by arranging a supporting rubber pad.

[0038] A second submersible pump 9 is provided at the input end of the water inlet assembly 3, and two sets of water supply pipes are provided at the output end of the second submersible pump 9. Before the sorting work starts, the second submersible pump 9 is placed below the sea level to provide the sorting device with seawater raw materials for sorting. Seawater is extracted from the sea and transported to the double-conical cylinder 1 through the water supply pipe to promote the generation of a vortex in the barrel.

[0039] A first arc-shaped connecting wall 11 is provided at the connection between the two groups of vertebrae of the double-conical cylinder 1, a second arc-shaped connecting wall 12 is provided at the bottom edge of the double-conical cylinder 1, and a discharge port 13 is provided at the bottom of the second arc-shaped connecting wall 12.

The two groups of water supply pipes output by the second submersible pump 9 are respectively connected to the No. 2 and No. 4 side water inlet pipes in the water inlet assembly 3. The first submersible pump 8 and the second submersible pump 9 can work simultaneously, and can also independently supply water to the sorting device. The water input by the side water inlet pipes can form vortices of different shapes according to the water flow rate and flow velocity, and the operation of the first submersible pump 8 and the second submersible pump 9 can be controlled according to the sorting requirements.

[0042] A bottom-inlet and middle-drain vortex sorting device provided by an embodiment of the utility model is arranged at a specified position of the hull through a cylinder support frame 5, and a second submersible pump 9 is placed below the sea level. The second submersible pump 9 is used to input seawater from a water supply pipe into each group of water inlet components 3. The impact angle formed by multiple groups of water flows and the side wall of the double-conical cylinder 1 can form a vortex of a certain scale in its inner cavity. As the water flow is continuously added, the vortex is continuously enlarged and water continues to accumulate upward. The mud and sand carried by the seawater flows out from the discharge port 13, and the seawater and the benthic organisms it carries are decelerated through the gradually widened cylinder of the upper vertebral body, and the water flow and the benthic organisms are pushed to the center of the cylinder by using the fluid properties, so that the drainage component 2 can discharge the water flow from the center of the cylinder through the hollow drainage pipe 21, thereby realizing the performance control of the bottom-inlet and middle-drain of the sorting device.
