Abstract

The utility model discloses a screening machine with multiple cylinders whose structure is that: a frame is provided with a plurality of cylinder screens, and each cylinder screen is composed of a cylinder frame fixed to thereof rotating shafts and a plurality of cylinder collars; wherein, at the outer edge of the cylinder frame, along the shaft direction, the cylinder collars are provided with intervals to form ring-shaped screen apertures; the rotating shaft of each cylinder screen is installed parallel to the frame; the cylinder collars are inserted into the screen apertures of thereof adjacent cylinder screen; Through a continuous belt, a motor is connected with a speed reducer, a coupling and the rotating shafts connected with a chain drive; two ends of the rotating shaft are connected to the frame respectively through a bearing and a drive bearing; one end of the frame is higher, and the other end of the frame is lower; the higher end of the frame is connected with a feed hopper whose outlet is connected to the inside of the end head of the cylinder screen, and the lower end of the frame is connected with a material discharge hopper inside the screen. The advantages of the utility model are: high production; little power consumption; simple structure; easy maintenance and installation; the classification efficiency of screening which can be more than 99. 9%; that cylinder collars of the adjacent cylinders are inserted with each other and are mutually cleaned even though the blocking materials and the high calcimine materials can be easily removed without blocking.

Description

Many shaft screens extension set

Technical field

The utility model relates to a kind of classification that is widely used in the solid material in the multiple industries such as chemical industry, electric power, medicine, grain and oil, light industry, metallurgy, cleaning, impurity elimination etc.Belong to the screening machine technical field.

Technical background

Prior art is the cage rolling separating screen as denomination of invention, and its structure has only a cartridge type sieve, and mechanical service efficiency is low.Finish cleaning work, the manufacturing cost height by fixed mount and a special sieve cleaning mechanism that is provided with.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of at many shaft screens extension set that the cartridge type sieve more than two or two is set on the same frame.Have mechanical service efficiency height, need not to be provided with specially characteristics such as screen cleaning device, low cost of manufacture.Technical solution of the present utility model: its structure is that several cartridge type sieves are housed on frame, each cartridge type sieve is made up of tube frame and several circles of being fixed on each axis of rotation, tube circle axial spacing on tube frame outer rim is wherein arranged and is constituted the ring-type sieve aperture, the shaft parallel of each cartridge type sieve is installed on the frame, the tube circle inserts in the sieve aperture of adjacent with it cartridge type sieve, motor connects reductor by driving-belt, shaft coupling, rotating shaft, rotating shaft and chain transmission are joined, two ends of rotating shaft pass through bearing respectively, drive bearing is connected on the frame, one end height of frame, the other end is low, the high-end place of frame taps into hopper, the outlet of feed hopper inserts in the termination of cartridge type sieve, and the lower of cartridge type sieve connects material discharge bucket in the sieve.Advantage of the present utility model: these facility have the output height, power consumption is few, simple in structure, engaged position is little, for ease of maintenaince, characteristics such as installation, simultaneously according to material properties, the sieve aperture that apolegamy is suitable just can reach output requirement and separating effect.The screen route is long, the classification efficiency height, and the screen classification efficiency can reach more than 99.9%; Sieve cover cleaning: adjacent roller tube circle inserts mutually, cleaning mutually, even if get stuck or high pigment material also can easily be removed unlikely obstruction; As adopt frequency control, can better guarantee the screen index; Can design screw mechanism in the screen drum and play the promotion material, the high and low end of screening machine be differed reduce, the material stroke increases, and increases the screen route; This machine is hermetically sealed, good looking appearance, easy accessibility.And establish the inlet scoop, negative pressure and environment protection.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is vertical views of Fig. 1.

Among the figure 1 is frame, the 2nd, feeding cylinder, the 3rd, bearing block, the 4th, driving end bearing block, the 5th, undersize material discharge bucket, the 6th, material discharge bucket, the 7th in the sieve, a frame, the 8th, tube circle, the 9th, shaft coupling, the 10th, decelerator, the 11st, motor, the 12nd, driving-belt, the 13rd, chain transmission, the 14th, rotating shaft, the 15th, sieve aperture, the 16th, cartridge type sieve.

The specific embodiment

The contrast accompanying drawing, two cartridge type sieves 16 are housed on frame 1, two cartridge type sieves 16 are made up of tube frame 7 and several circles 8 of being fixed on each axis of rotation 14 respectively, tube circle 8 axial spacing on tube frame 7 outer rims is wherein arranged and is constituted ring-type sieve aperture 15, the rotating shaft 14 of each cartridge type sieve 16 is installed in parallel on the frame 1, tube circle 8 inserts in the sieve aperture 15 of adjacent with it cartridge type sieve 16, motor 11 connects reductor 10 by driving-belt 12, shaft coupling 9, rotating shaft 14, rotating shaft 14 is joined with chain transmission 13, two ends of rotating shaft 14 are respectively by bearing 3, drive bearing 4 is connected on the frame 1, one end height of frame 1, the other end is low, and the high-end place of frame 1 taps into hopper 2, and the outlet of feed hopper 2 inserts in the termination of cartridge type sieve 16, the lower of cartridge type sieve 16 connects material discharge bucket 6 in the sieve, and sieve aperture connects undersize material discharge bucket 5 15 times.

Many shaft screens extension set is achieved in that actuating motor 11 to the screening impurity elimination of material, motor 11 rotates by the rotating shaft 14 that driving-belt 12, reductor 10, shaft coupling 9 drive in one of them cartridge types sieve 16, and another cartridge type sieve 16 turns round simultaneously by the driving-belt in the rotating shaft 14 12.Material sieves an end of 16 through each cartridge type that feed hopper 2 imports hollow respectively, and under the rotation and the acting in conjunction of material gravity of the cartridge type sieve 16 that has certain axioversion angle, material hangs down end motions to cartridge type sieve 16, and obtains the classification impurity elimination processing of sieve aperture 15 simultaneously.Send into feed bin from material material discharge bucket 6 in sieving that sieve aperture 15 gets off, the material that moves to cartridge type sieve 16 low ends is then derived through undersize material discharge bucket 5.The utility model and monotubular drum screen extension set may utilize same material, however the cartridge type sieve 16 that the utility model can produce more than two or two be installed on the frame, it has greatly improved mechanical service efficiency.Owing to cartridge type sieve 16, sieve aperture 15 are to utilize tube circle 8 on the mutual cartridge type sieve 16 to insert in time to be emptied when the work, so it need not to be provided with specially sieve cleaning mechanism.
