Embodiment 1

[0019] Such as figure 1 As shown, in a preferred embodiment of the present invention, the large-scale microalgae separation, collection and drying equipment includes a feed hopper, a material conveying system, a blast heating system, a collection device and a filter belt cleaning tank.

[0020] The flocculation-sedimented microalgae culture solution is placed in the feeding hopper 1 . The material conveying system consists of a filter belt 21 , a plurality of rollers 22 and a motor 23 . The porosity of the filter belt is 0.1mm. The filter belt 21 is arranged in an annular shape and is driven by a plurality of rollers 22 , one of which is connected with a motor 23 . The blast heating system is made up of blast heater 31, wind knife 32 and wind cover 33. The collection device consists of a scraper 41 and a collection bucket 42 .

[0021] The top of the annular filter belt 21 is horizontally arranged as a working area, and the bottom of the ring is a cleaning area. One end o...

Abstract

The invention discloses large-scale microalgae separation, collection and drying equipment. The large-scale microalgae separation, collection and drying equipment comprises a feed hopper, a material conveying system, a blast heating system, a collection device and a filter strip cleaning tank. The equipment can be used for continuously finishing algae liquid dehydration, separation, drying and collection processes. The problem of small-size and high-water-content large-scale recovery of particles such as energy microalgae, edible microalgae and medicinal microalgae is solved.

Description

technical field [0001] The invention relates to a large-scale microalgae harvesting device, in particular to a microalgae harvesting device for dehydrating and separating microalgae culture liquid while drying. Background technique [0002] Microalgae cultivation has been widely used in the fields of energy, food, pharmaceuticals, and feed. However, due to the small size of microalgae and the low concentration in the culture medium, it is very difficult to harvest them. For large-scale microalgae cultivation , Harvesting microalgae from algae liquid has always been a bottleneck problem, which has become one of the main factors restricting the large-scale production of microalgae culture. The current separation and collection methods of microalgae mainly include: centrifugation, filtration, flocculation, and air flotation. There is no large-scale harvesting equipment for the whole process, so it is urgent to develop a high degree of automation supporting composite microalgae...
