Abstract

The utility model belongs to the technical field of preparation equipment, and particularly relates to a novel hydrocyclone, which comprises a column, a feed port, an insertion pipe, an overflow pipe, an inverted cone and a sand setting port, wherein the feed port is arranged on the lateral surface of the upper end of the column, the insertion pipe is arranged on the upper portion of the column, the overflow pipe is connected with an upper opening of the insertion pipe, the inverted cone is connected with a lower opening of the column, and the sand setting port is connected with the lower end of the inverted cone. The novel hydrocyclone is characterized in that the insertion pipe is a cone-frustum-shaped pipe fitting with a thin upper portion and a thick lower portion, a screen is mounted at the bottom of the cone-frustum-shaped pipe fitting, the ratio of the inner diameter of a bottom orifice of the insertion pipe to that of a top orifice of the insertion pipe is 1.5-2:1, and the ratio of the effective area of the bottom screen to the sectional area of the top orifice is 1.2-1.5:1. Fine-grain materials and water move upwardly and inwardly and are discharged from the overflow pipe to form overflow after being screened by the bottom screen of the insertion pipe; and the grain size of the overflow can be ensured strictly after the overflow is controlled in a screened manner. As the insertion pipe is provided with the thin upper portion and the thick lower portion, more fine-grain materials have the chance to enter the overflow, and then the problem of entrainment of fine grains in settled sand is relieved, so that classification efficiency is increased.

Description

The novel hydropower cyclone

Technical field

The utility model belongs to the preparation equipment technical field, is specifically related to a kind of novel hydropower cyclone.

Background technology

As classifying equipoment, hydrocyclone now is widely used among the bargh.Hydrocyclone partly is made up of feed port, insertion pipe, overflow pipe, cylinder, cone, spigot etc.Its operation principle is: in feed port tangentially entered the cyclone cylinder, under gravity and centrifugal action, downward, the outwards motion of coarse granule material was through spigot discharge becoming sand setting under certain pressure for ore pulp; Fine granular materials and water make progress, inwardly motion, through insertion pipe, overflow pipe discharge becoming overflow, thereby realize classification.From the hydrocyclone practical application effect, its advantage is: volume is little, simple structure, and the unit are disposal ability is big, does not have running gear, convenient operating maintenance.But because hydrocyclone is not strict with the particle size classification, so carries coarse granule secretly in the overflow, carry fine grained in the sand setting secretly, classification efficiency waits to improve.

Summary of the invention

The purpose of this utility model is to provide a kind of novel hydropower cyclone, on the basis that keeps the hydrocyclone advantage, the hydrocyclone structure is improved, and alleviates to carry secretly in the overflow and carries fine grain problem in coarse granule, the sand setting secretly, improves classification efficiency.

The purpose of this utility model is achieved through the following technical solutions.

Novel hydropower cyclone of the present utility model, comprise cylinder, be located at the feed port of this cylinder upper side, be located at the insertion pipe on this cylinder top, insert the overflow pipe that is connected suitable for reading of pipe therewith, the reverse taper that is connected with the end opening of described cylinder, the spigot that is connected of the lower end of reverse taper is characterized in that described insertion pipe is the truncated cone-shaped pipe fitting up-thin-low-thick, that the bottom is equipped with screen cloth therewith.

The bottom mouth of pipe of described insertion pipe is 1.5～2: 1 with the ratio of top spout diameter, and bottom screen cloth effective area is 1.2～1.5: 1 with the ratio of top mouth of pipe sectional area.

The operation principle of novel hydropower cyclone of the present utility model is: in feed port tangentially entered the cyclone cylinder, under gravity and centrifugal action, downward, the outwards motion of coarse granule material was through spigot discharge becoming sand setting under certain pressure for ore pulp; Fine granular materials and water upwards, inwardly motion, discharge by overflow pipe and become overflow through inserting screen cloth screening back, pipe bottom, thus the realization classification.Overflow is through screening control, and overflow granularity is able to strict guarantee.It is up-thin-low-thick to insert pipe, guarantees that more fine has an opportunity to enter among the overflow, alleviates and carries fine grain problem in the sand setting secretly, thereby improved classification efficiency.

The beneficial effects of the utility model are: can significantly improve classification efficiency.With certain Mining Limited Company thickness grading operation is example: adopt YLSF type cyclone, 0～74 μ m grain size content β can reach 95% in the overflow, 0～74 μ m grain size content θ reduces to 30% in the sand setting, classification matter efficient is=(β-α) * (÷ α ÷ (100-α) ÷ of α-θ) * 100 (β-θ) * 100%=62.2%, improve 19.8%.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail.

As shown in Figure 1, novel hydropower cyclone of the present utility model, comprise cylinder 4, be located at the feed port 1 of these cylinder 4 upper side, be located at the insertion pipe 2 on these cylinder 4 tops, insert the overflow pipe that is connected 3 suitable for reading of pipe 2 therewith, the reverse taper 5 that is connected with the end opening of described cylinder 4, the spigot 6 that is connected of the lower end of reverse taper 5 is characterized in that described insertion pipe 2 is the truncated cone-shaped pipe fitting up-thin-low-thick, that the bottom is equipped with screen cloth 2-1 therewith.

As shown in Figure 2, the bottom mouth of pipe of described insertion pipe is 1.5～2: 1 with the ratio of top spout diameter, and bottom screen cloth effective area is 1.2～1.5: 1 with the ratio of top mouth of pipe sectional area.

The operation principle of novel hydropower cyclone of the present utility model is: in feed port tangentially entered the cyclone cylinder, under gravity and centrifugal action, downward, the outwards motion of coarse granule material was through spigot discharge becoming sand setting under certain pressure for ore pulp; Fine granular materials and water upwards, inwardly motion, discharge by overflow pipe and become overflow through inserting screen cloth screening back, pipe bottom, thus the realization classification.After overflow was controlled through screening, overflow granularity was able to strict guarantee.It is up-thin-low-thick to insert pipe, guarantees that more fine has an opportunity to enter among the overflow, alleviates and carries fine grain problem in the sand setting secretly, thereby improved classification efficiency.

The beneficial effects of the utility model are: can significantly improve classification efficiency. Take certain Mining Limited Company thickness grading operation as example: adopt YLSF type cyclone, 0～74 μ m grain size content β can reach 95% in the overflow, 0～74 μ m grain size content θ reduces to 30% in the sand setting, classification matter efficient is=(β-α) * (÷ α ÷ (100-α) ÷ of α-θ) * 100 (β-θ) * 100%=62.2%, improve 19.8%.
