Technical Field

The invention relates to a cyclone separation device with an underflow length self-adaptive function.

Background

The hydrocyclone is also called as a hydrocyclone and is an important separation device in the prior oil-water separation devices, can integrate concentration and dehydration by separating mixtures with different densities by utilizing a centrifugal force field, has the advantages of simple structure, convenient operation, no moving parts, small occupied area, large treatment capacity, high separation efficiency and the like, and has wide application markets in various fields of coal dressing, petroleum, chemical engineering and the like. The underflow split ratio, as an important operating parameter for evaluating the operating performance of a hydrocyclone, often has a significant effect on the separation efficiency of the hydrocyclone. However, in the practical application process of the cyclone, the problem that the application of the cyclone is limited due to low separation efficiency under many separation conditions with unstable liquid inlet amount is generally caused by the fact that the cyclone cannot maintain the optimal underflow flow dividing rate.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a novel cyclone separator length adaptive underflow device, which is a spring-controlled adaptive structure and can contract or extend under the action of a pressure until the spring force of the device is balanced with the pressure of the underflow liquid, so that the length of the underflow pipe is changed. The underflow pipe length self-adaptive base device suitable for the hydrocyclone can enhance the applicability of the hydrocyclone separation equipment under the condition of unstable liquid inlet quantity, improve the separation efficiency of the hydrocyclone and enhance the feasibility and the applicability of a hydrocyclone separation system.

The technical scheme of the invention is as follows: a cyclone separator length self-adaptive underflow device comprises an underflow bottom pipe, a liquid guide cup, a sealing snap ring, a liquid guide cup seat, a self-adaptive spring and a lower packing snap ring; the unique character lies in:

the bottom flow bottom pipe is formed by welding a large cylindrical straight pipe and a vertical small cylindrical branch pipe, two ends of the bottom flow bottom pipe are respectively provided with a flange plate with a corresponding size, a heavy phase flow guiding slope with a certain inclination is arranged inside the other end of the large cylindrical straight pipe, and a base clamping groove is formed in the heavy phase flow guiding slope; the base clamping groove is used for placing an underflow self-adaptive base; the liquid guide cup is a hollow horn-shaped pipeline, the upper end of the liquid guide cup is a horn bearing opening, and a raised annular spring snap ring is arranged on the periphery of the liquid guide cup; the upper sealing clamp ring is a stepped annular clamp ring and has a structure with a narrow upper part and a narrow lower part; the liquid guiding cup seat is a hollow cylindrical barrel, and a limiting step ring is arranged at the lower end of the liquid guiding cup seat. The lower packing snap ring is a stepped annular snap ring, and the main structure of the lower packing snap ring comprises a lower sealing small diameter and an upper limiting large diameter.

The annular spring snap ring on the periphery of the liquid guide cup is used for limiting the upper limit of the spring; the limiting stepped ring at the lower end of the liquid guide cup seat is used for limiting the lower packing snap ring; the upper sealing clamp ring is a stepped annular clamp ring, and the structure with the narrow upper part and the narrow lower part is used for fixing the upper seal of the base of the liquid guide cup and the upper limit of the liquid guide cup; the sealing small diameter of the lower enclosure of the lower packing snap ring is used for lower sealing of the liquid guiding cup seat, and the limiting large diameter of the upper enclosure is used for fixing the lower limit of the self-adaptive spring and the component.

The invention has the following beneficial effects: when the device is connected with a cyclone underflow end diameter flange, underflow liquid which is centrifugally separated by the hydrocyclone enters an underflow bottom pipe through an underflow cavity inlet, wherein medium of heavy phase is distributed at the periphery of the center of the bottom pipe under the action of larger centrifugal force and is discharged from a heavy phase outlet along a heavy phase flow guide slope, and light phase is gathered at the center of the bottom pipe under the action of smaller centrifugal force and is discharged along a liquid guide cup. When the liquid coming from the hydrocyclone is increased, the horn bearing opening on the liquid guide cup can bear larger underflow hydraulic pressure due to large stress area, so that the pressure is transmitted to the self-adaptive spring through the spring snap ring on the liquid guide cup, and the lower end of the self-adaptive spring is limited by the lower sealing snap ring, so that the spring can be contracted due to the action of pressure until the spring elastic force of the spring is balanced with the underflow hydraulic pressure, so that the length of the underflow pipe is changed, and the optimal underflow ratio of the hydrocyclone in which the underflow pipe is located is maintained; conversely, when the liquid coming from the hydrocyclone is reduced, the self-adaptive spring extends the length of the spring due to smaller pressure, so that the length of the underflow pipe is changed, and the optimal underflow ratio of the hydrocyclone can also be maintained. In the process, the upper sealing snap ring and the lower sealing snap ring ensure the sealing performance of the underflow self-adaptive base, and prevent underflow liquid from entering the base, so that the structures of the spring and other parts are rusted, and the service life of the spring and other parts is shortened.

The device can be applied to the unstable working condition that the liquid inlet amount is suddenly high or low, self-balance of different underflow liquid pressures is realized by additionally installing the self-adaptive spring, the length adjustment of the underflow pipe is realized, the split ratio of the hydraulic cyclone separation equipment is adjusted, so that the separation is carried out between phases under the working state with good separation performance, the treatment process is simple, the installation is convenient, and the continuous and efficient separation under the working condition of variable flow can be realized.

The following is a detailed description:

firstly, the cyclone separation technology is used as an efficient multiphase separation technology, the density difference between two phases or multiple phases is utilized to realize the phase-to-phase separation under the action of centrifugal force, and the device needs to be matched with a cyclone for common use, so the device can be used in the fields of petroleum, chemical industry, food, paper making and the like and has considerable application prospect;

secondly, underflow liquid which is centrifugally separated by the hydrocyclone enters an underflow bottom pipe through an inlet of an underflow cavity, wherein a medium of a heavy phase is distributed at the periphery of the center of the bottom pipe due to larger centrifugal force and is discharged from a heavy phase outlet along a heavy phase flow guide slope, a light phase is gathered at the center of the bottom pipe due to smaller centrifugal force and is discharged along a liquid guide cup, and the underflow liquid can be applied to an unstable working condition with high and low liquid inlet quantity, so that the hydrocyclone keeps good separation effect;

and when the liquid inlet amount of the hydrocyclone is changed, the horn bearing opening on the liquid guide cup can bear larger underflow hydraulic pressure due to large stress area, so that the pressure is transmitted to the self-adaptive spring through the spring snap ring on the liquid guide cup, and the lower end of the self-adaptive spring is limited by the lower sealing snap ring, so that the spring can keep the elastic force of the spring balanced with the underflow hydraulic pressure due to the stress action, thereby changing the length of the underflow pipe and keeping the optimal underflow ratio of the hydrocyclone in which the underflow pipe is located. The cyclone separation system can automatically change the length of the underflow pipe according to the change condition of the liquid inlet quantity under the unstable working condition that the liquid inlet quantity is suddenly high or low, so that the underflow split ratio is adjusted to keep the cyclone separation device in a high-efficiency running state;

finally, the cyclone separator length self-adaptive underflow device comprises an underflow bottom pipe, a liquid guide cup, a sealing snap ring, a liquid guide cup seat, a self-adaptive spring and a lower packing snap ring, and comprises six parts, the principle and the process are simple, the installation is convenient, and the continuous and efficient separation under the variable-flow working condition can be realized;

in summary, the length adaptive underflow device for the cyclone separator provided by the invention adopts a self-adaptive structure controlled by a spring, and no report is found for applying the device to the cyclone separation technology. The inventive device which can self-adaptively adjust the length of the cyclone separator through the spring is additionally arranged at the underflow port, and the length of the underflow pipe can be automatically changed according to the change condition of the liquid inlet quantity, so that the underflow split ratio is adjusted to ensure that the cyclone separator keeps a high-efficiency operation state.

The working principle of the cyclone separator length self-adaptive underflow device is described as follows:

the self-adaptive principle related to the device of the invention is as follows: after the device is connected with a cyclone underflow end diameter flange, underflow liquid which is centrifugally separated by a hydrocyclone enters an underflow bottom pipe 1 through an underflow cavity inlet 5, wherein medium of heavy phase is distributed on the periphery of the center of the bottom pipe due to larger centrifugal force and is discharged from a heavy phase outlet along a heavy phase diversion slope 11, and light phase is gathered in the center of the bottom pipe due to smaller centrifugal force and is discharged along a liquid diversion cup 6. When the liquid coming from the hydrocyclone is increased, the bell-mouth bearing port 12 on the liquid guide cup 6 can bear larger underflow hydraulic pressure due to large stress area, so that the pressure is transmitted to the self-adaptive spring 9 through the spring snap ring 13 on the self-adaptive spring, and the lower end of the self-adaptive spring 9 is limited by the lower sealing snap ring 10, so that the spring can be contracted due to the action of the compressive force until the spring elastic force of the spring is balanced with the underflow hydraulic pressure, thereby changing the length of the underflow pipe and keeping the optimal underflow ratio of the hydrocyclone in which the underflow pipe is located; conversely, when the liquid coming from the hydrocyclone is reduced, the self-adaptive spring 9 extends the length of the spring due to smaller pressure, so that the length of the underflow pipe is changed, and the optimal underflow ratio of the hydrocyclone can be maintained. In the process, the upper sealing snap ring 7 and the lower sealing snap ring 10 ensure the sealing performance of the underflow self-adapting base 3, and prevent underflow liquid from entering the base, so that the structures of the spring and other parts are rusted, and the service life of the spring and other parts is shortened.
