Detailed Description

In order to make the objects, technical solutions and advantages of the technical solutions of the present utility model more clear, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present utility model. Like reference numerals in the drawings denote like parts. It should be noted that the described embodiments are some, but not all embodiments of the present utility model. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present utility model fall within the protection scope of the present utility model.

Furthermore, two or more of the elements in the figures may be implemented in a single element or a single element shown in the figures may be implemented as multiple separate elements.

Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model belongs. The terms "first," "second," and the like in the description and in the claims, are not used for any order, quantity, or importance, but are used for distinguishing between different elements. Likewise, the terms "a" or "an" and the like do not necessarily denote a limitation of quantity. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

The utility model provides a microalgae collecting device which is used in a microorganism extraction process, the type of algae cells to be collected is not limited, but the microalgae separating cavity structure is particularly suitable for extracting the algae cells.

In general, the microalgae collecting apparatus provided by the utility model mainly comprises an algae liquid collecting cylinder 1 and a microalgae separating cavity 2, wherein reference can be made to fig. 1, which shows the arrangement relationship of the algae liquid collecting cylinder 1 and the microalgae separating cavity 2.

As shown in figure 1, the device is divided into two parts of an algae liquid collecting cylinder 1 and a microalgae separating cavity 2, when in use, the microalgae separating cavity 2 needs to be sunk at the bottom of the algae liquid collecting cylinder 1, and the foam stabilizing block 203 needs to be in a state with pressure resistance in the sinking process to ensure the attaching state of the algae liquid collecting cylinder 1 and the microalgae separating cavity 2, so that the quality of extracting algae cells is prevented from being influenced by friction collision of the microalgae separating cavity 2 in the algae liquid collecting cylinder 1 during subsequent algae cell collection;

after the first step is completed, the microalgae culture solution to be extracted is poured into the microalgae liquid collection cylinder 1 along the inner wall of the microalgae separation cavity 2, the microalgae liquid is primarily screened by a clamping block arranged on a boss 209 through a layer of filtering area 208 through a rough filtering net 211 arranged in the clamping block 210 to separate large-volume impurities in the microalgae liquid, and the microalgae liquid after rough filtering enters the cone-shaped liquid outlet area 202.

The lifting handle 205 gradually increases the height of the microalgae separation cavity 2, and the microalgae liquid can flow into the conical liquid outlet area 202 from the water drain hole 206 into the microalgae liquid collection cylinder 1, and the microalgae cells can be filtered out by the bolting silk drain pocket arranged on the conical liquid outlet area 202.

It should be noted that, as the pores on the surface of the bolting silk for collecting cells may be blocked, a small amount of residual algae liquid in the cone-shaped liquid outlet area 202 is left to open the water draining valve 207 to remove the residual algae liquid, and then the bolting silk leakage pocket is clamped by using tweezers, so that the microalgae cells separated from the bolting silk leakage pocket can be observed and inspected.

It should be noted that the mesh number of the bolting silk leakage pockets needs to be changed correspondingly according to the size of algae to be detected, and the screening is needed to be carried out for many times for detecting small microalgae cells.

The device is simple to manufacture and can achieve the purpose of extracting microalgae cells with lower cost.
