Abstract
Description
Technical Field
[0001] This invention relates to a disc separator, specifically a nozzle-type disc separator enclosure, belonging to the field of engineering machinery technology. Background Technology
[0002] The nozzle-type disc separator is a type of disc separator suitable for materials with relatively high impurity content and uniform particle size. It is a continuous spray slag separator. Normally, all the slag discharged should pass through the slag chamber channel. However, due to the high velocity and strong recoil of the discharged slag, if the gap between the bottom of the drum and the isolation cover is not properly designed, some slag can flow into the vertical shaft cavity. This slag can then enter the vertical shaft bearings, causing damage and affecting the normal operation of the nozzle-type disc separator. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a material with a reasonable structure, convenient use, and the ability to achieve continuous and normal separation of materials with low light phase content and high slag phase content.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a nozzle-type disc separator isolation cover, comprising an isolation cover body, wherein the isolation cover body is installed on the flange of the inner cavity of the body component of the nozzle-type disc separator, and is composed of an isolation ring, an isolation pad and an isolation disc below it connected and fixed in sequence. The top of the isolation ring is about 10mm lower than the slag spray nozzle of the rotating drum so that the slag can be sprayed into the slag discharge channel. The isolation ring, isolation pad and isolation disc are assembled into one unit and fixed to the flange of the inner cavity of the body component by bolts.
[0005] Furthermore, the upper surface of the isolation disc has a groove that matches the isolation ring.
[0006] Furthermore, the isolation ring is made of 304 stainless steel; its sides are inclined outwards, and its lower end face has an inward bend, which is inserted into the slot of the isolation disc, and the number of bends is the same as the number of slots.
[0007] Furthermore, the upper end face of the isolation ring is 9mm~11mm lower than the slag spray nozzle of the separator drum.
[0008] Furthermore, the number of bends on the lower end face of the isolation ring is 6.
[0009] Furthermore, the lower end face of the isolation ring is bent into six pieces and inserted into the slot of the isolation disc, extending into the slot of the isolation disc.
[0010] Furthermore, the bottom of the isolation ring has evenly distributed through grooves.
[0011] Furthermore, the number of through slots is six, to ensure the required strength and the size of the flow channel.
[0012] Furthermore, the isolation cover pad is placed on the isolation plate, is ring-shaped, and has 6 screw holes evenly distributed along its circumference. It is made of wear-resistant non-metallic material.
[0013] Compared with existing technologies, the present invention solves the problem of slag flowing into the vertical shaft cavity during the use of the nozzle-type disc separator, ensuring that the nozzle-type disc separator can operate normally and continuously regardless of the material it processes.

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings:
[0025] This invention provides a nozzle-type disc separator isolation cover, such as... Figure 2As shown, a new isolation shield replaces the original one. The new isolation shield consists of three parts: an isolation plate, an isolation ring, and a pad.
[0026] The isolation ring has a certain height. After being assembled with the isolation disc and pad and installed on the separator, its upper end face is about 10mm lower than the slag spray nozzle of the rotating drum. The upper end face of the isolation ring has a small bend around the entire circle. Its inner diameter on one side is about 5mm smaller than the outer diameter of the rotating drum. Its sides are inclined outward at a certain angle from top to bottom, and its bottom is composed of 6 evenly distributed ribs. It is made of 304 stainless steel.
[0027] The six ribs at the lower end of the isolation ring are inserted into the six slots on the top of the isolation plate, and the upper surface of the lower end of the isolation ring is flush with the upper surface of the isolation plate.
[0028] The sides of the isolation ring are tilted outward at a certain angle from top to bottom to facilitate the outflow of a small amount of slag that has flowed in.
[0029] The pad is a ring-shaped part with six evenly distributed screw holes. The pad is placed on the isolation plate and is made of wear-resistant non-metallic material.
[0030] These three parts are assembled as one unit and fixed with screws to the flange on the inside of the machine body of the separator frame component.
[0031] This ensures that the backflowing slag does not enter the vertical shaft cavity during normal operation of the separator. If a small amount of slag flows in during separator shutdown, it can be drained through the grooves on the isolation ring. If the separator drum sinks during operation, the bottom of the drum will first rub against the pads on the isolation disc. Since the pads are made of non-metallic materials, this provides protection for the drum.
[0032] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects:
[0033] This solves the problem of slag flowing into the vertical shaft cavity during the use of the nozzle-type disc separator, ensuring that the nozzle-type disc separator can operate normally and continuously regardless of the material it processes.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the specific embodiments described above. The specific embodiments and descriptions in the specification are merely for further illustrating the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the claims and their equivalents.
