Description
Technical Field
The invention belongs to the technical field of material separation, and particularly relates to a disc centrifuge with a quick installation structure.
Background
The disc separator is a vertical centrifuge, and a rotary drum is arranged at the upper end of a vertical shaft and is driven by a motor through a transmission device to rotate at a high speed. The drum is provided with a group of disk-shaped parts, namely disks, which are mutually sleeved together. A small gap is left between the disks. The suspension (or emulsion) is fed into the drum through a feed pipe located in the center of the drum. As the suspension (or emulsion) flows through the gaps between the discs, the solid particles (or droplets) settle by the centrifuge onto the discs to form a sediment (or liquid layer). The sediment slides along the surface of the disc to be separated from the disc and is accumulated at the part with the largest inner diameter of the rotary drum, and the separated liquid is discharged out of the rotary drum from the liquid outlet. The disc is used for shortening the settling distance of solid particles (or liquid drops) and expanding the settling area of the rotary drum, and the production capacity of the separator is greatly improved due to the disc arranged in the rotary drum. The solids accumulated in the drum are removed manually by disassembling the drum after the separator is shut down, or discharged from the drum through a slag discharge mechanism without shutting down the separator.
The slag discharge mode of the disc separator is as follows: the automatic deslagging device has three structures of manual operation, automatic operation and nozzle, wherein the automatic deslagging is widely applied, the working piston is used for deslagging automatically, the principle of the automatic deslagging device is that the working piston moves up and down through a special structure, the working piston moves up during working to form a closed cavity, materials are separated in the closed cavity, and when slag is accumulated to a certain degree and needs to be discharged, the working piston moves down to remove the slag and part of liquid is discharged out of a rotary drum, so that the automatic deslagging is realized.
In the existing disc separator, a rotary drum cover is tightly pressed on the rotary drum cover through a main lock ring, and a rotary drum body is connected with the main lock ring through threads, so that the rotary drum cover and the rotary drum body can be fixed by the main lock ring. Because the diameters of the rotary drum body and the main lock ring are more than 1m, certain difficulty and higher cost exist in the thread machining of the large-diameter part. In addition, when the main lock ring is screwed into the rotary drum body, at least two operators are needed if the main lock ring is installed in a manual mode, and otherwise, special equipment is needed to smoothly complete threaded connection. Therefore, the connection mode has inconvenience in processing and inconvenience in installation.

Further, the outer wall of the main lock ring 4 is provided with a positioning block 6, preferably fixed by screws. The inner wall of the annular part 103 of the rotary drum body 1 is provided with a positioning groove 101; the length of the positioning groove 101 is greater than that of the positioning block 6. The main lock ring 4 has a first circumferential position and a second circumferential position relative to the drum body 1, when the main lock ring 4 is at the first circumferential position, the rear end of the positioning block 6 is in contact with the rear end of the positioning groove 101, and the accommodating blind hole 105 is communicated with the locking groove; when the main lock ring 4 is located at the second circumferential position, the front end of the positioning block 6 contacts with the front end of the positioning groove 101, and the accommodating blind hole 105 is separated from the locking groove. The angle positioning of the main lock ring 4 and the rotary drum body 1 during rotation can be facilitated through the positioning block 6.
Further, the inner wall of the second semicircular groove 401 is provided with a rubber patch. When the steel ball 7 enters the locking groove, the steel ball 7 is pushed by the end face of the second semicircular groove 401 to be extruded into the locking groove, so that the axial stability of the steel ball 7 in the locking groove is improved, and the axial movement of the main locking ring 4 and the drum body 1 is avoided.
Further, the locking device further comprises a locking block 8, when the primary lock ring 4 is located at the second circumferential position, the locking block 8 can be just inserted into a space formed by the positioning block 6 and the positioning groove 101, so that the primary lock ring 4 cannot move circumferentially.
Further, when the main lock ring 4 is in the first circumferential position, the steel ball 7 can move from the bottom of the receiving blind hole 105 to the top thereof under the action of magnetic attraction.
Furthermore, the number of the first semicircular grooves 107, the second semicircular grooves 401, the accommodating blind holes 105 and the steel balls 7 is three, and the first semicircular grooves, the second semicircular grooves, the accommodating blind holes 105 and the steel balls 7 are uniformly distributed in the circumferential direction; the number of the positioning grooves 101, the positioning blocks 6 and the locking blocks 8 is one or three.
Before the drum cover 3 and the main lock ring 4 are installed, the steel ball 7 is attracted to the outer wall of the annular portion 103 of the drum body 1 through a magnetic member and is located outside the accommodating blind hole 105, and is attracted by magnetic attraction. Then, the drum cover 3 is put into the drum body 1, and the positioning flange 302 of the flange portion 301 of the drum cover 3 is placed on the positioning boss 104 so as not to move downward, supported by the positioning boss 104. At this time, the main lock ring 4 is placed in the annular portion 103 of the drum body 1, the positioning block 6 is inserted into the positioning groove 101, the main lock ring 4 is moved to a first circumferential position relative to the drum body 1, the magnetic member is removed, and the steel balls 7 roll into the lock groove under the action of gravity. Then slightly turning to the main lock ring 4 to reach the second circumferential position, the steel ball 7 moves to the depth of the lock groove along with the end part of the second semicircular groove 401 under the pushing of the end part of the second semicircular groove, at the moment, the lock groove is not communicated with the accommodating blind hole 105 any more, and therefore, under the limitation of the steel ball 7, the main lock ring 4 cannot move, and the drum cover 3 is pressed tightly. When the device is disassembled, only reverse operation is needed. Compared with the installation of the main lock ring 4 in the prior art, the installation of the main lock ring 4 can be completed only by rotating a small angle, and the operation process is simple and efficient.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
