On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] The utility model is a kind of extruded branch pile, for example Figure 1~2 As shown: it includes a stirring tank 1 and a sedimentation tank 17 arranged on the left and right, the stirring tank 1 includes a stirring tank body, the top of the stirring tank body is provided with a stirring tank top 2, the tank top of the stirring tank is provided with a feed liquid inlet 3, an extractant feeding port 4 and a stirring device, the stirring device includes a stirring shaft 14, a stirring blade 15 and a stirring motor 9 for driving the stirring shaft to rotate.

[0023] In this embodiment, the stirring shaft 14 is guided and moved in the up and down directions and assembled on the tank top 2 of the stirring tank. A motor support 10 is floatingly arranged on the tank top of the stirring tank through a spring 8. The lower end of the spring 8 is fixedly connected to the tank top of the stirring tank, and the upper end of the spring 8 is fixedly connected to the lower end of the motor support 10. The stirring motor 9 is arranged on the motor support, and a cam driving mechanism for driving the motor support to move upward is arranged between the stirring tank and the motor support.

[0024] The cam drive mechanism includes a left motor 5 and a right motor 11 which are symmetrically arranged on the left and right sides of the stirring motor. The left motor 5 and the right motor 11 are located between the liquid inlet 3 and the extractant feeding port 4. The motor shaft of the left motor is connected to a left drive shaft 6, and the motor shaft of the right motor is connected to a right drive shaft 12 which rotates synchronously with the left drive shaft. The left drive shaft is fixed with a left push cam 7, and the right drive shaft is fixed with a right push cam 13. The synchronous rotation of the left drive shaft and the right drive shaft is achieved by synchronously controlling the left motor and the right motor. The left drive shaft and the right drive shaft are coaxially arranged.

[0025] When in use, the left driving shaft and the right driving shaft respectively drive the left pushing cam and the right pushing cam to rotate slowly, for example, at a rotation speed of 1 to 3 circles per minute, the left pushing cam 7 and the right pushing cam 13 push the bottom of the motor support, so that the motor support moves upward, and when the motor support moves upward, the stirring shaft moves upward with the stirring blades, thereby realizing the stirring of the slurry in different height areas, thereby improving the stirring effect of the slurry, and when the left pushing cam and the right pushing cam move to a low position, the motor support can move downward under the joint action of the spring and the deadweight of the motor support.

[0026] The sedimentation tank includes an intermediate rigid tank body 18, and an upper side corrugated pipe section 19 capable of being extended and retracted up and down is arranged at the upper end of the intermediate rigid tank body 18, and a top plate 21 is arranged on the top of the upper side corrugated pipe section 19, and a lower side corrugated pipe section 20 capable of being extended and retracted up and down is arranged at the lower end of the intermediate rigid pipe section 19, and a bottom plate 22 is arranged at the bottom of the lower side corrugated pipe section 20, a light extraction liquid outlet 24 is arranged on the upper side corrugated pipe section, and a heavy extraction liquid outlet 25 is arranged on the lower side corrugated pipe section, a tank body support 23 is fixed on the intermediate rigid tank body, and a connecting pipe 16 is connected to the intermediate rigid tank body.

[0028] In the utility model, after the marine biological active material liquid is stirred in the stirring tank, it flows into the sedimentation tank through the connecting pipe, and is layered and settled in the sedimentation tank according to different densities, with the heavier extract falling and the lighter extract rising. According to the layer height of the extract, the telescopic length of the upper side bellows and the telescopic length of the lower side bellows can be reasonably adjusted, thereby adjusting the height of the light extract outlet and the height of the heavy extract outlet to meet the corresponding liquid outlet requirements. The light and heavy in the utility model are relative, and the density of the light extract is less than that of the heavy extract, so it is called light.

[0029] In the above description of this specification, unless otherwise clearly specified and limited, the terms "fixed", "installed", "connected" or "connected" should be understood in a broad sense. For example, with regard to the term "connection", it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise clearly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model according to the specific circumstances.

[0030] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "center", "longitudinal", "lateral", "clockwise" or "counterclockwise", etc., which indicate the orientation or position relationship, are based on the orientation or position relationship shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation. Therefore, the above-mentioned orientation or position relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0031] In addition, the terms "first" or "second" used in this specification to refer to numbers or ordinals are only used for descriptive purposes and cannot be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
