Abstract
The utility model belongs to the technical field of pellet screening of mining industries, particularly relates to a roller type screening machine with adjustable clearance, and comprises a screening machine frame and a group of screening rollers. Each screening roller comprises a driving device, a rotary drum, a bearing, a bearing seat and a gasket clamped between the bottom plane of the bearing seat and the upper plane of the screening machine frame. The group of screening rollers include a group of screening rollers I with the same clearance and a group of screening rollers II with the same clearance. The group of screening rollers II are respectively arranged between every two adjacent screening rollers I in a stagger mode, and central inclined planes B formed by rotary drum centers in the group of screening rollers I are located above central inclined planes C formed by rotary drum centers in the group of screening rollers II. The roller type screening machine with adjustable clearance has the advantages that adjacent rotary drums have height difference, and clearance between the rotary drums can be adjusted by changing the height of one rotary drum by means of selection of thickness dimension and quantity of the gasket. The roller type screening machine with adjustable clearance is convenient to operate, normal production is not affected, time and labor are saved, and utilization rate of equipment is increased.
Description
Technical field
The utility model belongs to mine industry pelletizing material sieving technology field, particularly a kind of roller type sieving machine of adjustable clearance.
Background technology
In mine industry, roller type sieving machine generally is positioned at below the balling disk (-sc), is used for sieving the pelletizing raw material (green-ball) that balling disk (-sc) is produced.Its effect is that green-ball that balling disk (-sc) is made is divided into Three Estate; Screened out when wherein the granule of granularity especially little (< 8mm) and not balling-up is through the screening machine leading portion and made ball again; Granularity moderate (8mm ~ 16mm) fall into belt through the screening machine back segment to get into next production link, granularity excessive (> 16) then falls into anti-ore deposit funnel through screening machine fully and handles again.The moderate green-ball diameter that is used to produce of granularity often is not unalterable in process of production; May be in order to improve output with the particle size diameter expanded range; Perhaps the particle size diameter scope is dwindled in order to improve quality of green pellets; And roller directly can diminish owing to long term wear gradually aborning, and this just needs a kind of roller type sieving machine that can among a small circle, regulate sieve roller spacing.Yet roll screen such in the actual production is actually rare, even if having, also all is to regulate the roll screen gap along the materials flow direction, regulates certain some roll gap like this, will inevitably cause the adjusting that thereupon links of other roller, and change amount and workload are all big especially.
Summary of the invention
It is a kind of simple to operate, time saving and energy saving that the purpose of the utility model is to provide, and local fine setting even need not stopped to stop production and just can be regulated the roller type sieving machine of the adjustable clearance of roller type sieving machine roll gap.
The purpose of the utility model realizes through following technical proposals:
The roller type sieving machine of the utility model adjustable clearance; Comprise screening machine frame and the one group of sieve roller that tilts to be located on this screening machine frame; This sieve roller is by drive unit; The cylinder that is connected of drive unit therewith, the bearing that is connected of cylinder both ends therewith, the bearing block that is connected of bearing therewith; Shim pack on this bearing block baseplane and the screening machine frame of jumping the queue between the plane is formed; It is characterized in that described one group of sieve roller by forming with one group of spacing sieve roller I with one group of sieve roller II of spacing, described one group of sieve roller II is staggered respectively to be located in said one group of sieve roller I between each adjacent sieve roller I, and centroclinal the B that the centre of the drum in said one group of sieve roller I forms is arranged in the top of centroclinal C of said one group of centre of the drum's formation of sieving the roller II.
Described shim pack is one group of pad that 1 ㎜-10 ㎜ different-thickness is formed.
The utility model has the advantages that:
1) changes conventional centre of the drum of sieving roller and be installed in the method in the same plane; Make between adjacent cylinder and the cylinder and have difference in height; So in a single day, change the height of a certain cylinder, the gap between the adjacent roller also changes thereupon, thereby reaches the purpose of adjusting play;
2) the utility model is adjusted the height of cylinder through the pad quantity of different size of adjustment shim pack, and this local the change do not need integral demounting, and operation is very easy, also can not influence ordinary production, and is time saving and energy saving and improve utilization rate of equipment and installations.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cutaway view of the utility model Fig. 1.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in 2; The roller type sieving machine of the utility model adjustable clearance; Comprise screening machine frame 3 and the one group of sieve roller that tilts to be located on this screening machine frame; This sieve roller is by drive unit 1-4; The cylinder 1-1 that is connected of drive unit 1-4 therewith, the bearing 1-3 that is connected of cylinder 1-1 both ends therewith, the bearing block 1-2 that is connected of bearing 1-3 therewith; Shim pack 1-5 on this bearing block baseplane and the screening machine frame of jumping the queue between the plane forms; It is characterized in that described one group of sieve roller by forming with one group of spacing sieve roller I 1 with one group of 2 of sieve roller II of spacing, described one group of sieve roller II 2 is staggered respectively to be located in said one group of sieve roller I 1 between each adjacent sieve roller, and centroclinal the B that is formed centrally among the cylinder 1-1 in said one group of sieve roller I 1 is arranged in the top of centroclinal the C that the centre of the drum of said one group of sieve roller II 2 forms.
Described shim pack 1-5 is one group of pad that 1 ㎜-10 ㎜ different-thickness is formed.Change the height of sieve roller through the thickness of adjustment shim pack, thereby regulate the gap between the sieve roller.
Like Fig. 1; During installation; Install differently with conventional roll screen, center lines of its all sieve roller intermediate rolls but lay respectively in two plane B being parallel to each other, the C not in same clinoplain; All on clinoplain B, centre of the drum's line of one group of sieve roller II 2 is all on the C of plane for centre of the drum's line of one group of sieve roller I 1.Centre of the drum's line of each adjacent sieve roller all lays respectively in B or the C plane.When certain cylinder serious wear, roller directly attenuate, or when need regulating roll gap, only need the height of this roller two end axles bearing is got final product through the shim pack adjustment, this operation even can under the situation that does not influence production, accomplish.
