Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, in particular to a conveying device for a disc separator. Background Art

[0002] Disc separator is a kind of equipment commonly used for solid-liquid separation or liquid-liquid separation, and its working principle is mainly based on the action of centrifugal force. In the disc separator, the material is sent into the high-speed rotating drum through the conveying device. Under the action of centrifugal force, materials with different specific gravities are separated and discharged separately. As an important part of the disc separator, the conveying device is responsible for smoothly and continuously feeding the material into the drum to ensure the smooth progress of the separation process; the centrifugal field force generated by the equipment when it rotates at high speed, in the centrifugal field force, the material is subjected to different centrifugal forces due to different specific gravities, and the heavier solids are deposited on the drum wall, while the light liquid phase flows along the outer cone surface of the disc toward the axis to the upper part, and is discharged from the light liquid port through the light liquid centripetal pump. The conveying of the disc separator is based on the action of centrifugal force, and the separation and conveying of materials are achieved through the cooperation of the drum and the disc.

[0003] In the prior art, there is a disc-type separation slag collection mechanism with publication number CN218221371U, which includes: a slag collection funnel, which is fixedly installed at the slag discharge port of the disc-type separator, a uniform discharge mechanism installed at the bottom of the slag collection funnel, and a pile leveling mechanism installed below the uniform discharge mechanism. The pile leveling mechanism flattens the materials piled into a conical structure by pressing the materials downward, effectively preventing the materials from spilling, and evenly presses the materials at too high a position to all directions around.

[0004] However, in actual use, although the separated solid slag is discharged, there is a lack of a conveying structure for the heavy phase liquid and the light phase liquid. The traditional centripetal pump is prone to conveying dead corners when outputting the separated heavy phase and light phase liquid, and it is easy to accumulate impurities or particulate matter, causing blockage problems, thereby affecting the use efficiency of the disc separator.

The lower end of the supporting collar 224 is fixedly connected with a liquid edge component 223, and the inner ring surface of the liquid edge component 223 is fixedly connected with the outer surface of the inlet conveying pipe 3; the outer side of the liquid edge component 223 is provided with a centripetal pump group 222, and the centripetal pump group 222 is fixedly installed on the outside of the centripetal pump group 1 312, and the centripetal pump group 222 is arranged inside the upper side of the drum top cover 221, and the top surface of the inner cavity of the drum top cover 221 is fixedly installed with a reverse impeller plate 226;

[0036] In this embodiment, the mixed liquid to be separated is transported to the inside of the drum 22 through the inlet conveying pipe 3, and the main shaft 11 is driven to rotate by the driving structure of the disc separator body 1, thereby driving the drum 22 to rotate as a whole inside the centrifuge casing 21. At this time, the mixed liquid is subjected to different centrifugal forces due to different specific gravities, and the heavier solids are deposited on the inner wall of the drum 22, while the heavy liquid is output through the heavy phase liquid channel formed between the disc top cover 232 and the outer side of the inlet conveying pipe 3, and the clear liquid is output through the light phase liquid channel between the inner side of the drum top cover 221 and the outer side of the centripetal pump group 1 312. The separated heavy phase liquid and light phase liquid are discharged from the outside of the equipment through the drain pipe 1 311 and the drain pipe 2 321 respectively, thereby achieving the purpose of separating solid slag and liquid.

[0037] Embodiment 2, refer to the attached Figure 1-14On the basis of the first embodiment, in order to achieve the diversion effect on the heavy phase liquid and the light phase liquid: the centripetal pump group 1 312 includes an impeller casing 3121, an impeller bottom plate 3122 and a guide plate 1 3123, a heavy phase liquid channel is provided between the inner ring surface of the impeller casing 3121 and the outer surface of the inlet conveying pipeline 3, and the inner ring surface of the impeller bottom plate 3122 is fixedly connected to the outer surface of the inlet conveying pipeline 3; the two ends of the guide plate 1 3123 are respectively fixedly connected to the lower surface of the impeller casing 3121 and the upper surface of the impeller bottom plate 3122 , six groups of guide plates 1 3123 are arranged in a circular array about the central axis of the inlet conveying pipeline 3, guide plates 2 3124 are arranged at the center of two groups of guide plates 1 3123, and flow grooves are formed between one group of guide plates 2 3124 and the two groups of guide plates 1 3123; a guide cone hood 3125 is arranged between the guide plates 1 3123 and the guide plates 2 3124, and the guide cone hood 3125 is a conical structure that gradually narrows from bottom to top, and the inner ring surface of the guide cone hood 3125 is fixedly connected to the outer surface of the inlet conveying pipeline 3;

[0038] In this embodiment, if Figure 3-Figure 6 As shown, under the action of the centrifugal force, the heavy phase liquid and the light phase liquid are respectively output to the outside. Since the principles of the centripetal pump group 1 312 and the centripetal pump group 2 322 are the same, the implementation principle of the centripetal pump group 1 312 is taken as an example below: the heavy phase liquid enters between the disc top cover 232 and the uppermost disc 23 under the action of the centrifugal force, and the heavy phase liquid then flows between the impeller casing 3121 and the impeller bottom plate 3122 in the centripetal pump group 1 312. The fluid can be guided by the mutual cooperation of the guide plate 1 3123 and the guide plate 2 3124. Here, the height of the guide plate 2 3124 is designed to be the guide plate 1 3123. 123, and a group of guide plates 3124 is set between two adjacent groups of guide plates 1 3123 to form a flow groove. Through such a setting, the fluid is constrained by the guide plate 3124 and the two adjacent groups of guide plates 1 3123 at the same time, thereby reducing the relative vortex between the two adjacent guide plates 1 3123, reducing energy consumption, and increasing the outlet flow rate of the guide plate 1 3123 and the guide plate 2 3124, thereby increasing the head of the centripetal pump group 1 312, further improving the efficiency of the heavy phase liquid output, and avoiding the problem of blockage; it is worth noting that, if Figure 7 As shown, a guide cone hood 3125 is arranged between the guide plate 1 3123 and the guide plate 2 3124. The guide cone hood 3125 here can guide the fluid upward, and accelerate the central flow velocity of the fluid through the tapered structure design that gradually narrows from bottom to top; and can avoid excessive bends or diameter changes in the fluid to reduce the resistance and possibility of blockage of the heavy phase liquid in the pipeline, avoid excessive resistance caused by bending of the water flow, avoid water flow velocity loss when pumping water, and further optimize the flow path of the fluid.

[0039] Embodiment 3, refer to the attached Figure 1-14 On the basis of the second embodiment, in order to avoid the impact of the centripetal pump group 1 312 caused by the flowing fluid: the inner side of the disc top cover 232 and the upper inner ring surface of the drum top cover 221 are provided with an anti-collision guide component, the anti-collision guide component includes a guide ring 1 315, the guide ring 1 315 is a hollow ring plate structure, and the inner ring surface of the guide ring 1 315 is evenly provided with guide inclined columns; the top surface of the inner cavity of the disc top cover 232 is fixedly connected with a reverse impeller plate 1 316, and the inner side surface of the reverse impeller plate 1 316 is fixedly installed with a guide plate opposite to the impeller bottom plate 3122 and the guide plate 1 3123;

[0040] In this embodiment, if Figure 6 As shown, a guide ring 1 315 and a guide ring 2 325 are respectively arranged between the inner sides of the disc top cover 232 and the drum top cover 221. The implementation principle of the guide ring 1 315 is still taken as an example below: when the heavy phase liquid flows between the guide plate 1 3123 and the guide plate 2 3124, the lower section of the guide ring 1 315 can guide the fluid, and cooperate with the guide inclined column added on the inner side ring surface of the guide ring 1 315 to ensure uniform flow of the fluid, reduce local impact, and ensure that the fluid enters the guide plate 1 uniformly. 3123 and the guide plate 2 3124; it should be noted that by setting the directions of the centripetal pump group 1 312 and the centripetal pump group 2 322 to be consistent, and respectively setting the reverse impeller plate 1 316 and the reverse impeller plate 2 326 in opposite directions on the upper part of the two, through such a setting, the flow direction of the fluid is changed, so that the circumferential flow velocity of the mixed liquid is increased, the speed difference between the mixed liquid and the high-speed rotating disc 23 is reduced, the shear effect and emulsification phenomenon of the fluid are weakened, and the separation efficiency of the disc separator body 1 is improved.

[0041] Embodiment 4, refer to the attached Figure 1-14 On the basis of the third embodiment, in order to realize the segmentation and guidance of the fluid entering the centripetal pump group 1 312: a liquid edge component 1 313 is provided at the upper end of the guide cone cover 3125, and the liquid edge component 1 313 includes a fixed ring plate 3131 and a segmentation grid 3132. The fixed ring plate 3131 is provided with two groups, and the two groups of fixed ring plates 3131 are fixedly connected by multiple groups of segmentation grids 3132. The segmentation grids 3132 are arranged in a circular array about the central axis of the inlet conveying pipeline 3, and a liquid groove is provided between two adjacent groups of segmentation grids 3132;

[0042] In this embodiment, if Figure 10-13As shown, a group of liquid edge components 313 are arranged between the guide cone cover 3125 and the support ring 314. Here, the liquid edge components 313 are distributed on the inner side of the impeller sleeve 3121, and the lower end thereof is connected to the top of the guide cone cover 3125, so as to ensure that the fluid in the flow groove formed by the guide plate 2 3124 and the adjacent guide plate 1 3123 flows upward along the inclined surface of the guide cone cover 3125, and cooperates with the dividing bars 3132 arranged in an array to achieve the segmentation of the fluid, so that the fluid being transported can be divided from a large unit into multiple small units for upward output, thereby reducing the turbulence generated during output, reducing the jitter of the inlet conveying pipeline 3, and reducing the fluid output noise.

[0043] Embodiment 5, refer to the attached Figure 1-14 On the basis of the fourth embodiment, in order to avoid the problem that the noise generated during the fluid conveying affects the performance of the disc separator: a support assembly is arranged at the upper end of the liquid edge assembly 313, and the support assembly includes a support collar 314, which is installed on the inner side of the heavy phase liquid pan 31, and the support collar 314 is formed as a whole by two groups of mirror-distributed stacked ring plates and straight ring plates, and a reserved hole 3140 is opened on the inner wall of the lower end of the support collar 314; an inner recessed groove 3141 is arranged between the upper end of the support collar 314 and the inner cavity top surface of the heavy phase liquid pan 31, and the inner recessed groove 3141 is provided. A support sheet 3142 is fixedly installed on the inner surface of the support ring 141, and the support sheets 3142 are provided with multiple groups and are arranged in a circular array about the central axis of the support ring 1 314, and a noise reduction component is provided between two adjacent groups of support sheets 3142; the noise reduction component includes a sound absorbing block 3143, and a sound absorbing cavity 31430 is provided on the inner surface of the sound absorbing block 3143, and an arc sheet 31431 is fixedly installed on the inner surface of the sound absorbing cavity 31430, and the arc sheet 31431 is designed to be an arc structure adapted to the inner cavity of the sound absorbing cavity 31430, and a sound penetration hole 31432 is opened on the inner wall of the arc sheet 31431;

[0044] In this embodiment, if Figure 13-14As shown, the upper end of the liquid edge component 313 is connected to the support ring 314, and the support ring 314 is set inside the heavy phase liquid pan 31. The fluid that has been divided and guided enters the outer edge of the support ring 314 through the reserved hole 3140 opened at the bottom end of the support ring 314. At this time, the fluid flows around the central straight ring plate of the support ring 314, and part of the fluid impacts the stacked ring plate at the upper part. The support sheet 3142 evenly arranged on the inner side of the sunken groove 3141 provides strength support for the overall structure of the support ring 314, and the support sheet 3142 here can be used as a partition element. Sound-absorbing blocks 3143 are filled between the support plates 3142 to reduce the impact and vibration of the fluid on the support ring 314. The cooperation between the arc-shaped plate 31431 on the inner side of the sound-absorbing cavity 31430 and the sound-permeating hole 31432 can realize the absorption of the noise generated by the fluid flow, reduce the vibration of turbulent flow, and improve the output effect of the disc separator on the heavy phase liquid and the light phase liquid. It further solves the problems of dead angle and easy blockage in the existing disc separator when conveying heavy phase liquid and light phase liquid, and ensures that the separated heavy phase liquid and light phase liquid are conveyed more smoothly without dead angles, thereby improving the use efficiency and separation effect of the disc separator.

[0045] The working principle and use process of the present invention are as follows: first, the mixed liquid to be separated is transported to the inside of the drum 22 through the inlet conveying pipe 3, and the main shaft 11 is driven to rotate by the driving structure of the disc separator body 1, so as to drive the drum 22 to rotate as a whole inside the centrifuge shell 21. At this time, the mixed liquid is subjected to different centrifugal forces due to different specific gravities. The heavier solids are deposited on the inner wall of the drum 22, and the heavy liquid is output through the heavy phase liquid channel formed between the disc top cover 232 and the outer side of the inlet conveying pipe 3, and the clear liquid is output through the light phase liquid channel between the inner side of the drum top cover 221 and the outer side of the centrifugal pump group 312; the heavy phase liquid enters the disc top cover 232 and the uppermost part under the action of centrifugal force. Between the layer discs 23, the heavy phase liquid flows in the centripetal pump group 1 312 to between the impeller casing 3121 and the impeller bottom plate 3122. Through the cooperation between the guide plate 1 3123 and the guide plate 2 3124, the fluid can be guided, the relative vortex between the two adjacent guide plates 1 3123 is reduced, the energy consumption is reduced, and the outlet flow rate of the guide plate 1 3123 and the guide plate 2 3124 is increased; then, the heavy phase liquid continues to flow through the liquid along the component 1 313, enters the heavy phase liquid pan 31, and the fluid flows around the central straight ring plate of the support ring 1 314, and is finally output through the drain pipe 1 311; and the light phase liquid is output through the light phase liquid pan 32 and the drain pipe 2 321.
