Description

EXTRACTOR WITH DUAL BUOYANCY SYSTEM
Technical Field
The present invention relates to an extractor which 1s applicable to extract oil slick, scum, algae, and sludge, and in particular, to an extractor with a dual buoyancy system.
Background
The applicant has long been committed to the development of a suspended floating algae extractor. “Suspended Floating Algae Extractor” is applied in 2012 with the application number of CN201220368333.6. A submersible pump with an upward water inlet is fixedly mounted on a rack. A plurality of diving depth adjustment apparatuses is circumferentially and uniformly distributed at the periphery of the rack. That is to say, vertical rods are distributed at the periphery of the rack. Lower ends of the vertical rods are respectively and fixedly connected to the rack, and upper ends of the vertical rods are processed with external threads. Floating balls are disposed on the vertical rods, and adjustment nuts are disposed at upper and lower parts of the floating balls corresponding to the vertical rods. The extractor may adjust a depth of the submersible pump by adjusting vertical heights of the floating balls on the vertical rods, so that salvage requirements of the extractor at different occasions can be met.
The applicant put forward “Suspended Extractor” with the application number
CN203924020U in 2014. The suspended extractor includes a rack. A submersible pump is mounted on the rack, and a water inlet of the submersible pump face upwards. Vertical rods are uniformly distributed at the periphery of the rack. Lower ends of the vertical rods are fixedly connected to the rack, and upper ends of the vertical rods are processed with threads. The vertical rods are paired in groups of two vertical rods adjacent to each other along a circumferential direction of the rack. Two vertical rods in each group are provided with cross rods. Positions of the cross rods corresponding to the vertical rods are provided with adjustment holes. The adjustment holes are sleeved on the corresponding vertical rods. Adjustment nuts are disposed on the upper and lower adjustment holes corresponding to the vertical rods. Floating balls are disposed on the cross rods. By using the adjustment nuts to adjust heights of the cross rods on the vertical rods, a relative height between the floating balls and the rack of the extractor is adjusted, so that the draft of the extractor can be adjusted.
Although the current two suspended extractors have been practically applied, the following advantages still exist. The floating balls fixed on the vertical rods or the cross rods are required to obtain buoyancy to support the operation of the extraction pumps. The depths of the extraction pumps are controlled by adjusting the heights of the floating balls or the cross rods on the vertical rods, so that the extraction port 1s guaranteed to be at an optimal water level to achieve an ideal extraction effect. If the extractor is large in processing capacity or needs to be equipped with large buoyancy, the required number of the floating balls is large. In addition, the upper parts of the floating balls are all above the water surface, resulting in disordered water surface, affecting aesthetics. Then, the extraction pump mounted on the rack is single in function, which is generally and only configured to extract algae. If the extraction pump is about to be configured to extract sludge, the rack structure of the extractor is required to be additionally designed.
Summary
In order to overcome the above disadvantages, the present invention provides an extractor with dual buoyancy system. By disposing two upper and lower buoyancy systems, a tloating body of the lower buoyancy system is completely immersed in water to provide basic buoyancy to an extraction pump. A floating body of the upper buoyancy system is partially exposed from a water surface. A distance between an extraction port of the extraction pump and the water surface or bottom is controlled by adjusting a relative height between the floating body and a rack. Through such a design, in addition to guarantee the required buoyancy of the extractor, the number of the floating bodies above the water surface may be greatly reduced, thereby making the water surface more artistic.
The present invention is implemented as follows. An extractor with a dual buoyancy system is applicable to extract oil slick, scum, algae, and sludge, and includes a rack. The extraction pump and two buoyancy systems providing buoyancy for the extraction pump are mounted on the rack. The two buoyancy systems are disposed up and down. The floating body of the lower buoyancy system is completely immersed in water to provide basic buoyancy for the extraction pump. The floating body of the upper buoyancy system is partially exposed from a water surface.
A relative height between the upper floating body and the rack is adjusted by means of thread stepless adjustment or latch grading adjustment, so as to maintain an appropriate height between the extraction port of the extraction pump and the water surface or bottom.
During the operation of the extractor, the upper and lower buoyancy systems are designed according to the buoyancy required to support the extraction pump. The lower buoyancy system is completely under the water surface. The floating body of the lower buoyancy system may be a rigid floating body. The buoyancy may be determined by a medium filled in the floating body.
The medium may be a gas phase, a liquid phase, or a mixture of the gas phase and the liquid phase. The floating body of the lower buoyancy system may also be an elastic body, and the buoyancy is determined by changing the drainage volume of the elastic body. The floating body of the lower buoyancy system may be designed into a continuous or spaced shape according to requirements, and may form a closed or open circle, which is not limited in theory.
The floating body of the upper buoyancy system generally adopts a rigid floating body, and may be applicable to adjust a relative height between the rigid floating body and the rack by means of thread stepless adjustment or latch grading adjustment, so as to cause the extraction port of the extraction pump and the water surface or bottom to be in an appropriate position, thereby efficiently complete an extraction operation.
An absorption port of the extraction pump is disposed upwards, and mainly configured to extract floating algae. The extraction port of the extraction pump is disposed downwards, and mainly configured to extract river bottom sludge. When the floating algae are extracted, in order to not block the accumulation of the floating algae, the rigid floating bodies of the upper buoyancy system are arranged at intervals.
When the rigid floating bodies of the upper buoyancy system are arranged at intervals, there are at least three rigid floating bodies to guarantee a balance. Through the design of less number of the floating bodies above the water surface, the aesthetics of the water surface is maintained.
The rack in the present invention is a frame-type rack. Position layout of the extraction pump, and the upper and lower buoyancy systems may be designed according to requirements. A desirable design method is to dispose the upper and lower buoyancy systems along a circumference using the extraction pump as a center. A specific structure of the rack may be designed into a feasible structure according to practicality and requirements, as long as the structure meets a requirement of fixing the upper and lower buoyancy systems and the extraction pump so as to guarantee the stable operation of the extractor.
The beneficial effects of the present invention include the following. The upper and lower buoyancy systems are disposed. The lower buoyancy system provides the basic buoyancy. The relative height between the floating body of the upper buoyancy system and the rack is adjusted.
In this way, a distance between the extraction port of the extraction pump and the water surface or bottom is controlled. Therefore, extraction efficiency can be enhanced, the number of floating bodies above the water surface is greatly reduced, and the water surface is more artistic. The designed rack is a streamlined frame-type rack, so that the rack is firm in structure. Therefore, the operation stability of the extraction pump can be improved.
