Abstract
The invention discloses an automatically cleanable drum screening machine. The automatically cleanable drum screening machine comprises a screening cylinder and a vibration screening device. The screening cylinder comprises a supporting frame and a circular screen which is arranged on the supporting frame. The automatically cleanable drum screening machine is characterized in that the supporting frame comprises isodiametric vibration striking pipes which are radially arranged on a center rotary shaft; the vibration screening device is a self-striking mechanism which comprises the vibration striking pipes, blocking plates and striking bodies; the blocking plates are arranged on the sides which are close to the screen and in the vibration striking pipes; the striking bodies are arranged in the vibration striking pipes; elevating plates are arranged in the vibration striking pipes; a 180, 120 or 90 degree angle is formed between the peripheries of the isodiametric vibration striking pipes. According to the automatically cleanable drum screening machine, continuous knocking vibration can be performed due to the action of gravity and the rotation function of the machine and accordingly the cleaning of the screen surface can be achieved, the extra energy consumption is not added, the continuous operation can be achieved, the screening function and the screening effect of the machine are enhanced, and the service life of the screen is long.
Description
Technical field
The present invention relates to screening installation, be specially a kind of cylinder round sifter that can Automatic clearance.
Background technology
Drum-type screening machine is a kind of industrial machinery that is widely used in the industries such as mine, cement, chemical industry.Its operation principle is that material is sent into after rotary screen by conveyer or bucket elevator, screened along with rotary screen rotates on the one hand, by the centrifugal force of drum rotating and jigging, be used for screening materials carrying, the material that granularity is large on the other hand flows forward along the gradient of cylinder, and the screen cloth by different meshes is sifted out gradually.The material that classification is sifted out falls into storage bin separately, then from manually transporting or carrying toward finished bin.
The rotating speed of the drum-type screening machine of this structure is very low, stable working, dynamic equilibrium are good, but its sieve aperture easily stops up distortion, and work area reduces, and causes screening efficiency low.Therefore rotary screen conventionally all disposes the external structure that impacts, by repeatedly impacting screen cloth abate obstruction material, make screen cloth keep unimpeded, if publication number is that the disclosed structure of CN202447277U " drum-type screening machine " comprises screen drum, casing, charging aperture and discharging opening, screen drum is arranged in casing, charging aperture is communicated to screen drum leading edge mouth through casing, screen drum trailing edge mouth is provided with discharging opening, is provided with screen cloth and joint band reinforcement on screen drum, and joint band reinforcement one side is provided with vibration hammer.The problem that this structure exists:
1, external beating unit, as affiliated facility, causes rotary screen complex structure, directly has influence on installation, debugging and the maintenance of equipment;
2, external beating unit need to newly increase power, has increased energy consumption, causes production cost to increase;
3, screen of screening machine intensity is limited all the time, and after directly beaten by external force, damaged acceleration, service life shorten, and also affect screening effect.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and a kind of cylinder round sifter that can Automatic clearance is provided, this drum-type screening machine does not increase unnecessary energy consumption, can realize and work continuously, can strengthen screening function and screening effect, and screen cloth is longer service life.
The technical scheme that realizes the object of the invention is as follows:
A kind of cylinder round sifter that can Automatic clearance, comprise sieve cylindrical shell and riddler device, the described cylindrical shell that sieves comprises support frame and be located at the screen cloth in support frame circle, unlike the prior art: described support frame comprises is located at the isometrical vibration pipe radially arranging on central rotating shaft; Described riddler device is from hit agency, describedly from hit agency, comprises vibration pipe, baffler and impacts body, and baffler is located in vibration pipe by screen cloth side, impacts body and is arranged in vibration pipe.
In described vibration pipe, be provided with riser.
Described each isometrical vibration pipe circumference is mutually 180 ° (two), 120 ° (three) or 90 ° (four) arrange.
Preferably, described each isometrical vibration pipe circumference mutually (four) in 90 ° arrange and to be crux.
When rotary screen rotates, will impact body and mention high point by riser, under the effect of gravity, fall to impacting central shaft, produce shaking force, and again fall to impacting baffler with the rotation of rotary screen, again produce vibrations, go round and begin again, complete the cleaning of screen cloth.
The present invention utilizes the spinfunction of Action of Gravity Field and machine to knock continuously vibrations, thereby realizes sieve cover cleaning, does not increase unnecessary energy consumption, can realize and working continuously, and strengthened screening function and the screening effect of machine, and the service life of screen cloth is longer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure, 1. screen cloth 2. vibration pipes 3. impact body 4. baffler 5. riser 6. central rotating shafts.
The specific embodiment
Below in conjunction with drawings and Examples, content of the present invention is further elaborated, but is not limitation of the invention.
Embodiment:
With reference to Fig. 1, a kind of cylinder round sifter that can Automatic clearance, comprise sieve cylindrical shell and riddler device, described in the cylindrical shell that sieves comprise support frame and be located at the screen cloth 1 on support frame, described support frame comprises is located at the isometrical vibration pipe 2 radially arranging on central rotating shaft 6; Described riddler device is from hit agency, describedly from hit agency, comprises vibration pipe 2, baffler 4 and impacts body 3, and baffler 4 is located in vibration pipe 2 by screen cloth 1 side, impacts body 3 and is arranged in vibration pipe 2.
In described vibration pipe 2, be provided with riser 5.
Each isometrical vibration pipe 2 circumference are mutually 180 ° (two), 120 ° (three) or 90 ° (four) arrange.
In Fig. 1, each isometrical vibration pipe 2 circumference are set to 90 degrees mutually and are crux.
The direction of motion that Fig. 1 cathetus arrow is iron ball, the direction of motion that camber line arrow is rotary screen.
Riser 5 is for promoting solid iron ball, and baffler 4 is for intercepting iron ball and being impacted, and solid iron ball is for generation of impact force.
When rotary screen rotates, solid iron ball is mentioned to high point by riser 5, under the effect of gravity, fall to impacting central rotating shaft 6, produce shaking force, and again fall to impacting baffler 4 with the rotation of rotary screen, again produce vibrations, go round and begin again, complete the cleaning of screen cloth.
