Description

Relative operation strong flushing type separation equipment based on three-section type front mixing

Technical Field

The invention belongs to the technical field of centrifugal sedimentation separation, and particularly relates to a relative operation strong flushing type separation device based on three-section type front mixing.

Background

In the centrifugal sedimentation separation process, the two-phase separation or single-phase clarification can be realized by utilizing the principle that the liquid density is poor and the liquids are mutually insoluble under the action of centrifugal force. The traditional centrifugal sedimentation equipment is characterized by mainly comprising a motor, a guide body, a rotary drum and a shell, wherein a partition plate is arranged in the guide body, a light phase guide hole is arranged below the partition plate, an axial heavy phase guide hole is formed between the side of the partition plate and the inner wall of the guide body, a heavy phase weir is arranged above the guide body, and a material inlet, a heavy phase outlet and a light phase outlet are arranged on the shell. When the structure is actually used, firstly, as the structure has no design of removing solids in liquid phase materials, the materials inevitably contain oligomers, impurities and the like, and once the solids enter the extractor, the solids are gradually deposited on the inner wall of the rotor under the action of centrifugal force. In the two-phase mixing, solids such as salt and crystals are gradually precipitated along with the mixing time, and the solids are deposited on the inner wall of the rotor. Thus, the current equipment on the one hand often requires prolonged mixing times in order to allow for sufficient precipitation or washing out of salts, crystals in the material. After the equipment structure is shaped, the mixing time is prolonged and can only be realized by reducing the flow and sacrificing the productivity, which obviously does not meet the production requirement; further, reducing the flow rate also makes it difficult to precisely control the mixing time, and the controllable range is extremely limited, which is a technical dilemma that the current equipment does not have; on the other hand, the solids deposited on the inner wall of the rotor also need to be cleaned and discharged regularly, and at present, the solids are cleaned manually after stopping the machine, which obviously brings no little obstruction to the production efficiency, the automation degree and the like. Therefore, a solution is needed.

5) In order to quickly accelerate the mixed liquid to the rotating speed of the rotor and prevent the mixed liquid from shaking in the rotor, the mixed liquid and the rotating speed of the rotor are not synchronous, and liquid baffle plates are uniformly distributed in the rotor.

Detailed Description

For ease of understanding, the specific structure and operation of the present invention will be further described herein with reference to FIGS. 1-7:

as shown in fig. 1, the actual structure of the present invention is that the driving motor 61 drives the main shaft 62 to rotate at a high speed through the coupling, and the steering is generally clockwise in a plan view. The rotor 20 is connected to the main shaft 62 to rotate therewith, thereby separating the inner materials. The rotor 20 is provided with a housing 30 coaxially on the outside thereof, which serves to collect liquid and to protect the corresponding rotating member from exposure. The rigid, desirably compliant housing 10 supports the entire apparatus. In addition, the invention is also provided with a material liquid inlet pipe 51 and a washing liquid inlet pipe 52, and the material, the washing liquid and the like are respectively fed according to the requirements of separation working conditions, and the pipe orifices are not distinguished. The separated liquid flows out from the light phase outlet 21 and the heavy phase outlet 22 at the upper part of the housing 30, respectively. The rotor 20 has a different structure, and the positions of the light phase outlet 21 and the heavy phase outlet 22 are different. The materials and the washing liquid enter the lower part of the rotor 20 through a material liquid inlet pipe 51 and a washing liquid inlet pipe 52, then enter the rotor 20, and under the action of centrifugal force, heavy phases with high density are close to the inner wall of the rotor 20 and are discharged through a heavy phase outlet 22; the light phase with small density is close to the center of the rotor 20 and finally discharged from the light phase outlet 21, so that the light phase and heavy phase separation process is completed. Before the materials and the washing liquid enter the rotor 20, the materials and the washing liquid mainly stay at the lower part of the shell 30, the rotation of the rotor 20 carries out preliminary mixing on the materials and the washing liquid, and the mixing strength and the mixing time determine the washing effect of the washing liquid.

The effect of clarification and separation is not achieved due to short mixing time, insufficient washing and difficult washing of impurities, or insufficient precipitation of solids. Thus, as shown in FIGS. 1-4, the present invention contemplates a variable volume mixing chamber 50 in the lower portion of the housing 30. The inner cavity of the mixing chamber 50 is used as a primary mixing chamber a, the primary mixing chamber a is coaxially arranged at the lower part of the shell 30 through a flange, the internal volume can be designed in a targeted manner according to the working condition of materials, the convenient replacement effect is realized through the interchangeability of the flange, and finally the variable volume design of the mixing chamber 50 is realized. Meanwhile, in order to ensure that materials and washing liquid can be fully mixed after entering the mixing chamber 50 under different volumes, the invention is also provided with a replaceable coaxial impeller 80 at the bottom of the rotor 20, and the coaxial impeller 80 is coaxially connected with the bottom of the rotor 20 through a connecting disc. To enhance the pumping effect of the coaxial impeller 80, a pump sleeve 31 may be provided coaxially. When the volume of the mixing chamber 50 is large, the coaxial impeller 80 can be replaced by a secondary impeller accordingly, and the pumping action is stronger. In the case of a secondary impeller, the outer diameter of the secondary impeller is smaller than the inner diameter of the pump sleeve 31, leaving a gap, and the gap size needs to be calculated according to the material characteristics to control the better pumping action.

As shown in fig. 3, the pump housing 31 is welded to the lower cover plate of the casing 30 as one body; the lower end of the pump sleeve 31 extends into the mixing chamber 50, and the upper end is positioned in the outer shell 30 so as to form a material passage by utilizing the cylinder cavity of the pump sleeve. When longer mixing times are required, the mixing chamber 50 may be designed as a mixing structure with a larger bottom diameter and a combined monolithic cone to increase the volume. As shown in fig. 4, the material inlet pipe 51 and the washing liquid inlet pipe 52 are disposed tangentially and opposite to the outer casing 30 of the mixing chamber 50, and the material and the washing liquid enter the mixing chamber 50 or the column-cone combined mixing chamber 50 tangentially at a certain pressure and are mixed with each other under the action of the feeding pressure. To enhance the mixing effect, 4 to 8 dispersing blades 53 are provided in the mixing chamber 50, and dispersing holes 54 are provided in the middle lower portion of the dispersing blades 53. The dispersion holes 54 of adjacent dispersion blades 53 are generally staggered, and the material is easy to form turbulence. Of course, as shown in fig. 3, when the number of the dispersion holes 54 of the current dispersion blade 53 is large, the number of the dispersion holes 54 of the adjacent dispersion blade 53 is large, and the mixing effect is ensured. The mixed material is pumped to the upper chamber of the housing 30 by the pumping action of the secondary mixing chamber b formed by the coaxial impeller 80 and the pump housing 31.

Further, as shown in fig. 1 and 3, an annular gap is formed between the outer wall of the rotor 20 and the outer shell 30, a transverse liquid pressing plate 40 is arranged at a proper position on the lower part of the inner wall of the straight cylinder of the outer shell 30, the entered material is pressed, and the gap is reserved between the transverse liquid pressing plate 40 and the outer wall of the rotor 20; at this time, the transverse liquid pressing plate 40, the housing 30 and the rotor 20 enclose together to form a three-stage mixing chamber c. As shown in fig. 2, in order to ensure that no material is accumulated above the lateral liquid pressing plate 40, a series of discharge holes 41 are formed at a lower position of the lateral liquid pressing plate 40.

The actual material mixing path of the invention is shown in figure 2: the material and the washing liquid enter a primary mixing cavity a where the mixing chamber 50 is positioned through a material liquid inlet pipe 51 and a washing liquid inlet pipe 52 at a certain pressure, and turbulent flow is formed through the dispersing holes 54 of the dispersing blades 53 under the action of the feeding pressure, so that the primary mixing purpose is achieved; the rotor 20 running at high speed drives the coaxial impeller 80 again, and under the action of the secondary mixing cavity b formed by the pump sleeve 31 and the coaxial impeller 80, a pumping action is formed, and a vortex is gradually formed at the center of the secondary mixing cavity b, so that a secondary mixing effect is achieved. The mixed liquor at the secondary mixing chamber b is then sucked into the tertiary mixing chamber c formed by the housing 30, the rotor 20 and the transverse liquid pressing plate 40; under the pressing action of the transverse liquid pressing plate 40, the flow of the mixed liquid in the three-stage mixing cavity c is blocked, the flow direction is changed, and under the rotating action of the outer wall of the rotor 20, the mixed liquid is accelerated to turbulent flow in the annular cavity in the three-stage mixing cavity c, and a plurality of small vortex flows are formed again, so that the three-stage mixing function is achieved. So far, the whole mixing flow strengthens the mixing effect of the mixed liquid and prolongs the mixing time.

Subsequently, as shown in fig. 1 and 5-6, the mixed liquor that meets the mixing requirements enters the rotating rotor 20 through the pre-opened apertures at the bottom of the rotor 20. In order to quickly accelerate the mixed liquor to the rotation speed of the rotor 20 and prevent the mixed liquor from 'shaking' in the rotor 20 to cause asynchronous rotation speed with the rotor 20, a series of liquid baffles 23 are uniformly distributed in the rotor 20. The number of the liquid baffle plates 23 is 4-8 according to the diameter of the rotor 20; the rotor 20 has a large diameter and a large number of liquid baffles 23. The bottom of each liquid baffle plate 23 is provided with a small number of through holes 24 so as to prevent each liquid baffle plate 23 from forming a closed space under the action of liquid to form an air plug.

After thorough mixing, the solids in the material will precipitate out and deposit under centrifugal force on the inner wall of rotor 20. Thus, the present invention is also provided with a cleaning core sleeve 70, as shown in FIG. 7. The cleaning core sleeve 70 is fixedly mounted at the table top of the frame 10 by a mounting seat and is kept coaxial with the rotor 20. The outer wall of the cleaning core sleeve 70 is provided with a high pressure nozzle 71 and communicates with the annular cavity of the cleaning core sleeve 70. At this time, the liquid sector ejected from each nozzle 71 completely covers the inner wall of the rotor 20, and no dead angle is removed. The upper part of the cleaning core sleeve 70 is provided with a cleaning port 72 which is connected with the annular cavity; the high-pressure cleaning liquid with the pressure not lower than 0.4MPa enters from the cleaning opening 72 and finally is sprayed out in a fan shape through the nozzle 71; at the same time, the rotor 20 rotates at a low speed, and the high-pressure spray cleaning effect is enhanced, so that the cleaning liquid can effectively wash away the solids deposited on the inner wall of the rotor 20, and then the solids are discharged through the emptying port 55 at the bottom. The data of the number of times of cleaning, the cleaning time, the type of cleaning liquid, the cleaning temperature, etc. are related by the solid characteristics.

To achieve the above design, the connection of the spindle 62 and the rotor 20 of the present invention is required at the bottom of the rotor 20 as shown in fig. 1 and 5. Therefore, the bottom of the rotor 20 is provided with a connecting seat, and the axis of the connecting seat is provided with a conical hole which is matched and connected with the lower end of the main shaft 62. Meanwhile, the outer diameter of the central hole at the rotor 20 and the central space of each liquid baffle 23 are required to be kept with proper size, so as to facilitate the installation and the disassembly of the cleaning core sleeve 70.
