Description
Technical Field
The invention relates to a cyclone, in particular to a cyclone for a fine sand recycling machine.
Background
A cyclone is a common separation and classification device, and the centrifugal sedimentation principle is commonly used. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone under a certain pressure, strong three-dimensional elliptical strong-rotation shearing turbulent motion is generated. The fine sand recycling machine utilizes the swirler to separate and classify fine sand, however, all parts of the swirler for the existing fine sand recycling machine cannot be detached, the whole set of equipment needs to be replaced due to abrasion, the cost is high, and the abrasion resistance is poor.
Disclosure of Invention
The invention provides a detachable swirler for a fine sand recycling machine, which aims at the technical problems that the swirler for the existing fine sand recycling machine is not detachable and has poor wear resistance.
Therefore, the technical scheme of the invention is that the swirler adopts an involute feeding mode and comprises an overflow connecting pipe, an overflow pipe, a feeding body, a cone, a bottom flow port and a feeding connecting pipe, wherein the bottom of the overflow connecting pipe is connected with the overflow pipe, and the overflow pipe is connected with the feeding body through a screw, so that the replacement is convenient; the bottom of the feeding body is detachably connected with the cone, the bottom of the cone is detachably connected with the underflow port, and the feeding connecting pipe is detachably connected with the feeding body; the feeding connecting pipe has a rectangular cross section.
Preferably, the lining is made of wear-resistant and corrosion-resistant polyurethane material.
Preferably, the cone comprises a large cone and a small cone, and the feeding body is connected with the large cone and the small cone through flanges.
Preferably, the lower part of the small cone is provided with a thread structure, and the underflow port is connected with the small cone through a nut.
Preferably, the feeding adapter is connected to the feeding body by a flange.
The cyclone separator has the beneficial effects that the cyclone separator adopts an involute feeding mode, so that materials entering the cyclone separator can be ensured to enter the cyclone separator in a laminar flow mode as much as possible, and the effect of pre-grading is achieved. The lining is made of wear-resistant and corrosion-resistant polyurethane materials, is light, wear-resistant and smash-resistant, is suitable for complex working conditions such as fine sand recovery in sand making of buildings, can be directly vulcanized on the shell, and can also be independently vulcanized and molded and then arranged in the shell. The cones are connected with each other through flanges, and the cones with different cone angles can be replaced according to different working conditions. The lower part of the small cone is provided with a thread structure, and the underflow port is connected with the small cone through a nut, so that the underflow port is convenient to replace.
