Problems solved by technology

However, it should be pointed out that because the surface texture of cyanobacteria is compact and not easy to damage, even if the water is removed by flocculants, the flocculants cannot effectively penetrate into the cyanobacteria, and naturally its water absorption effect is greatly reduced, resulting in the moisture content of the finished algae cake. High, which brings difficulties for the subsequent finished algae cake

Embodiment 1

[0037]As shown in Figures 1 and 2, the first extruding member 10 includes a plurality of extruding rods or extruding rollers 11a, and the center of the circle formed by the extruding rods or extruding rollers 11a is connected to the center of the extruding barrel. The center of the circle is on the same center of circle; the second extruding part 20 is a truncated extruding cylinder, the extruding cylinder is vertically arranged, and one end of the extruding cylinder has a large diameter and the other end has a small diameter; the first extrusion A plurality of extruding rods or extruding rollers 11a in the component 10 are attached to the inner peripheral side wall surface / or outer peripheral side wall surface of the extruding cylinder, and the cylinder formed by this plurality of extruding rods or extruding rollers 11a The inside or outside of the extrusion cylinder rotates circularly.

[0038] Such as Figure 1a As shown, the annular structure formed by extrusion rods or ex...

Embodiment 2

[0043] Such as figure 2 As shown, the first extruding member 10 is set as one or more extruding rods or extruding rollers 11b arranged in parallel, and the contact surface of the second extruding member 20 and the first extruding member 10 is set is flat.

[0044] The second extrusion part 20 in this embodiment is preferably a conveyor belt with a magnetic attraction mechanism, and the contact area between the extrusion roller 11b and the belt surface of the conveyor belt is the extrusion area.

Embodiment 3

[0046] Such as Figure 5 As shown, the first extruding member 10 is configured as an extruding roller 11c, and the outer peripheral surface of the extruding roller 11c is provided with a helical blade 12, and the second extruding member 20 is cylindrical, so The extrusion roller 11c is disposed inside the cylindrical second extrusion member 20 , and the blade edge of the blade 12 on the outer peripheral surface of the extrusion roller 11c is disposed close to the inner wall surface of the second extrusion member 20 .

[0047] Specifically, the second extruding part 20 is a straight cylindrical outer casing, the outer casing has a cylindrical cavity, and the cylindrical cavity constitutes an extrusion chamber of the outer casing for containing the mixed material. The two ends of the extrusion cavity are respectively provided with a feed end and a discharge end communicating with the cavity. A squeeze roller 11c with helical blades 12 is arranged coaxially in the extrusion cham...

Abstract

The invention belongs to the technical field of treatment of water surface blue-green algae, and in particular, relates to a blue-green algae extruding and crushing device. The device comprises a first extruding part and a second extruding part, wherein the contact surfaces of the first extruding part and the second extruding part are formed to an extruding and crushing area; the first extruding part and the second extruding part are respectively provided with magnetic sucking mechanisms on the contact surfaces thereof; and the device further comprises magnetic sucking particles absorbed by the magnetic sucking mechanisms to crush the blue-green algae. The device can effectively realize the purpose of convenient treatment of the blue-green algae so as to provide blue-green algae residues, lower in water content and easier to be treated, to subsequent treatment procedures, and is stable and reliable in operation and higher in treatment efficiency.

Description

technical field [0001] The invention belongs to the technical field of water surface cyanobacteria treatment, in particular to a cyanobacteria extrusion crushing device. Background technique [0002] Cyanobacteria are the earliest photosynthetic and oxygen-evolving organisms, and they have played a huge role in changing the earth's surface from an oxygen-free atmospheric environment to an aerobic environment. However, due to the extremely fast reproduction speed and strong vitality of cyanobacteria, in some nutrient-rich water bodies, cyanobacteria often multiply in large numbers in summer, and form a layer of blue-green and fishy-smelling floating foam on the water surface, causing water blooms. Large-scale cyanobacteria outbreaks will cause deterioration of water quality, and in severe cases may deplete the oxygen in the water and cause the death of fish, which is extremely harmful. [0003] In order to avoid the above-mentioned hazards of cyanobacteria, the main methods ...
