Description
Technical field
The utility model relates to the door closure retaining mechanism, particularly relates to a kind of door closure retaining mechanism of horizontal scraper discharging centrifuge.
Background technology
Horizontal scraper discharging centrifuge is a kind of scraper discharging perforated wall centrifuge of horizontal, automatic control, is applicable to the Separation of Solid and Liquid of the suspension of thin solid phase particles in containing, and is widely used in the separation of starch, salt and resinae material.In suspending operations for consolidation, machine down maintenance or when changing filter cloth, need to open door closure, each parts of its inside are fully washed, to stick material rotten and cause product quality defective thereby reduce.Simultaneously, can prevent that also material is to problems such as filter screen and siphon pipeline blockage.
According at present in the world to the demand of super-magnum centrifuge, our the domestic super-magnum centrifuge that can produce as GKH1800-N, this machine rotary drum internal diameter reaches 1800mm, starch yield can reach 10-11t/h, its door closure diameter has also reached more than the 2300mm simultaneously.In order to lock large diameter door closure like this, international uniform structure is exactly on manual locking mechanism basis, and 10 groups of door closure locks evenly are installed around door closure.Manual locking mechanism as shown in Figure 1, casing flange 1 is fixedlyed connected with locking bed 3, locking bed 3 links to each other with check lock lever 5 by rotational pin 4, set lever 6 and check lock lever 5 threaded engagement have the U-shaped fluting on the lock cover 7, the while fixedlys connected with door closure 2; When locking, check lock lever 5 is put into the U-lag of lock cover 7, rotational lock handle 6 makes, and casing flange 1 is tentatively locked with door closure 2.Lock fully by 10 groups of door closure locks then, the structure of door closure lock casing flange 1 is as shown in Figure 2 fixedlyed connected with locking bed 3, locking bed 3 links to each other with check lock lever 5 by rotational pin 4, the dual-side that two fixed blocks 8 are welded on respectively after casing flange 1 and door closure 2 closures is stupefied, and form projection with the stupefied place of dual-side, check lock lever 5 is becoming the L type near fixed block 8 with the high spot of the casing flange stupefied formation in 1 limit, when check lock lever 5 rotates to when being pressed on the fixed block 8, it is inboard with the projection of the casing flange stupefied formation in 1 limit that this L type is in fixed block 8, locking briquetting 9 has the annular of L type flange for both sides, it is enclosed within on the check lock lever 5, a flange is pressed on the check lock lever 5, it is inboard with the projection of the casing flange stupefied formation in 1 limit that another flange is in fixed block 8, the threaded engagement on 2 nuts 10 and the check lock lever 5.When locking, check lock lever 5 rotations are placed on the fixed block 8, locking briquetting 9 is enclosed within on the check lock lever 5, fastening nut 10, be locked briquetting 9 of casing flange 1 and door closure compresses with check lock lever 5, while check lock lever 5 and locking briquetting 9 are limited along the door closure free degree radially by these two fixed blocks 8 and the projection that casing flange 1 and door closure 2 form, thereby finish the locking of casing flange 1 and door closure 2.
Because door closure is that vertical installation adds that its diameter is bigger, lock extremely inconvenience of these door closure locks; Each door closure lock contains 2 nuts simultaneously, and complete machine is totally 20 nuts, and whole locking working strength is big, consuming time many, thereby causes the machine service efficiency to reduce.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model provides a kind of simple in structure, easy to operate, safe and efficient, horizontal scraper discharging centrifuge door closure retaining mechanism that can reach locking effect rapidly.
Horizontal scraper discharging centrifuge door closure retaining mechanism described in the utility model, it is installed in the outer ring edge of door closure, 10 groups of door closure locks on the generic centrifuge have been substituted, by the door closure retaining ring, gate stop, earrings, rotational pin, long stud, hydraulic cylinder, short stud is formed, wherein the door closure retaining ring is for having opening, not closed annular, its inner ring is fluted, the array gate stop is distributed on the door closure retaining ring and is attached thereto, the door closure retaining ring links to each other respectively with two earrings by rotational pin, two earrings also are connected by rotational pin with the cylinder body of two hydraulic cylinders, long stud is fixedlyed connected with two earrings, and short stud is fixedlyed connected with the piston rod of two hydraulic cylinders.
Before the locking centrifuge with cutter discharge of solid, the door closure that closes, mechanism is in locking state with manual locking, and the adjusted gate stop makes door closure retaining ring inner ring groove just in time match with the outer ring of door closure and casing flange in advance; Start the hydraulic cylinder on the retaining ring because the piston rod of two hydraulic cylinders is fixedly connected by short stud, therefore under the effect of pressure oil, about two hydraulic cylinder bodies respectively to the right, move left; Because two earrings are connected with the cylinder body of two hydraulic cylinders, two earrings are fixed by long stud again simultaneously, therefore when driving two earrings two hydraulic cylinder body move left and right the trend of move left and right being arranged, the motion of earrings is limited by long stud, the untie-sell that can only rotate is rotated, the extended distance that is driving the door closure retaining ring that is attached thereto constantly draws shortening in, thereby door closure is fitted tightly on the casing flange, reaches the locking purpose.During release, make hydraulic cylinder carry out above-mentioned reverse action, reach the effect of unclamping door closure, adjust gate stop then, the door closure retaining ring is flicked fully.
The utility model horizontal scraper discharging centrifuge door closure retaining mechanism has following beneficial effect:
1, the utility model mechanism is simple, maintenance, easy maintenance.Device just one a cover locking mechanism has cancelled being distributed in the equipment door closure door closure lock of 10 groups of machineries all around.
2, the utility model mechanism is easy to operate, can carry out locking function rapidly.The utility model only needs the primer fluid cylinder pressure, and the mechanical interlocking operation that need not to waste time and energy repeatedly just can be locked automatically.
3, sealing effectiveness was better after the utility model reached locking state, guaranteed the leakage of safety nothing.Door closure retaining ring inner ring groove cooperates and it is pressed with the whole outer ring of door closure and casing flange, and door closure and casing are also played sealing function simultaneously.
In order to obtain better effect, can take following measure:
1, the contact-making surface of door closure and casing flange and door closure retaining ring parts adopts polishing, and door closure retaining ring parts inner ring adopts zinc-plated polishing.Thereby prevent frictional heat between door closure retaining ring inner ring and door closure and the casing flange and cause door closure retaining ring parts burning phenomenon, improved the service life of this mechanism, also having prevented from simultaneously to fit because of door closure and casing flange does not sternly cause the door lock inefficacy.
2, install near switch in a pair of long stud left and right sides, this motion of mechanism is played a protective role, improved the reliability that mechanism uses.
3, gate stop comprise along door closure radially bolt and along the axial bolt of centrifuge.These bolts be used for adjusting the door closure retaining ring radially with axial position, to control it to the locking of door closure and casing flange with unclamp.
