Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, and particularly relates to a solid-liquid separator with anti-blocking function. Background Art

[0002] The solid-liquid separator adopts the side-in and side-out or side-in and bottom-out mode. The filtered liquid medium is pressed or pumped into the filter barrel through the pressure in the pipeline. The liquid medium to be filtered first passes through a stainless steel metal mesh for filtration, intercepting solid substances larger than 40 meshes in the circulating water; after passing through the metal mesh, the liquid is filtered by a filter bag supported by a supporting filter basket, achieving an ideal solid-liquid separation and the effect of filtering the liquid medium. Different filtering effects depend on filter bags with different precisions.

[0003] However, when the existing equipment is in use, there is a phenomenon that solid impurities accumulate on the inner wall of the filter mesh barrel during the filtration process and cannot be cleaned, resulting in blockage, and even damage to the filter mesh barrel due to blockage, leading to low filtration efficiency; frequently replacing the filter mesh barrel increases production costs, and it cannot discharge solid impurities by itself, resulting in the need to stop the equipment when cleaning solid impurities, which will reduce work efficiency, and the operation steps are complex, increasing the work load. Summary of the Utility Model

Specific Embodiment

[0025] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0028] Embodiment 1

[0029] Referring to Figures 1 to 3 , which is the first embodiment of the present utility model. This embodiment provides a solid-liquid separator that prevents blockage, including a main pipeline 1. Fixed vertical plates 2 are fixedly connected to both ends of the main pipeline 1. One end of the main pipeline 1 is connected to a liquid inlet pipeline 3, and the other end is connected to a liquid discharge pipeline 4. A filtering mechanism 5 is arranged in the inner cavity of the main pipeline 1. A discharging mechanism 6 is arranged outside the fixed vertical plate 2 on the side of the main pipeline 1 close to the liquid discharge pipeline 4. A driving motor 7 is fixedly installed outside the fixed vertical plate 2 on the side of the main pipeline 1 close to the liquid inlet pipeline 3.

[0030] Specifically, the filtering mechanism 5 includes a filtering pipeline 501, a filter mesh cylinder 502, a fixing ring 503, a driving rotating shaft 504 and a spiral blade 505.

[0031] Both ends of the filtering pipeline 501 are fixedly connected to both ends of the inner cavity of the main pipeline 1. The input end of the filtering pipeline 501 is communicated with the output end of the liquid inlet pipeline 3. The filter mesh cylinder 502 is fixedly inserted into the inner cavity of the filtering pipeline 501. The outer wall of the filter mesh cylinder 502 fits with the inner wall of the filtering pipeline 501. The fixing ring 503 is fixedly connected to the outer end of the filter mesh cylinder 502, and the fixing ring 503 is fixed in the fixing vertical plate 2. The driving rotating shaft 504 is rotatably connected to the inner cavity of the filtering pipeline 501. One end of the driving rotating shaft 504 is fixedly connected to the output end of the driving motor 7. The spiral blade 505 is fixed outside the driving rotating shaft 504, and the outer side wall of the spiral blade 505 fits with the inner wall of the filter mesh cylinder 502.

[0032] During use, connect the liquid inlet pipeline 3 to the raw liquid feeding pipeline, and connect the liquid discharge pipeline 4 to the filtered liquid pipeline. The liquid inlet pipeline 3 transports the raw liquid to the inner cavity of the filtering pipeline 501. The raw liquid flows from the input port of the filtering pipeline 501 to the inner cavity of the filter mesh cylinder 502. Leakage holes are provided on the side wall of the filtering pipeline 501. After the raw liquid enters the filter mesh cylinder 502, the solid impurities in the raw liquid are filtered by the filter mesh cylinder 502, so that the solid impurities are retained in the filter mesh cylinder 502, and the liquid flows into the main pipeline 1 through the leakage holes at the bottom of the filtering pipeline 501 and is discharged through the liquid discharge pipeline 4.

[0033] At the same time, the driving motor 7 drives the driving rotating shaft 504 and the spiral blade 505 to rotate. On the one hand, the solid impurities are transported along the main pipeline 1 to one side of the liquid discharge pipeline 4; at the same time, the rotation of the spiral blade 505 causes the outer side of the spiral blade 505 to scrape off the solid impurities attached to the inner wall of the filter mesh cylinder 502 and transport them to the output end of the filtering pipeline 501.

[0034] Furthermore, the blade spacing of the spiral blade 505 gradually decreases towards the direction close to the liquid discharge pipeline 4, so that the solid impurities are gradually squeezed during transportation, which is convenient for further squeezing out the water in the solid impurities.

[0035] When the filter mesh cylinder 502 needs to be replaced, remove the discharging mechanism 6, pull the fixing ring 503 outwards to drive the filter mesh cylinder 502 to move outwards, so that the filter mesh cylinder 502 is pulled out from the filtering pipeline 501, and then insert a new filter mesh cylinder 502 into the inner cavity of the filtering pipeline 501 to complete the replacement of the filter mesh cylinder 502.

[0036] In summary, through the coordinated work of each component, the problem that in the existing equipment during use, due to the accumulation of solid impurities on the inner wall of the filter mesh cylinder 502 during the filtering process, it cannot be cleaned and causes blockage, and even the filter mesh cylinder 502 is damaged due to blockage, is solved. The filtering efficiency is improved, and the problem of frequently replacing the filter mesh cylinder 502 to increase the production cost is solved.

[0037] Embodiment 2

[0038] Referring to Figures 1 to 5 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a discharging mechanism 6, and the discharging mechanism 6 includes a discharging pipeline 601, a pipeline inspection cover 602, a sealing pipe plug 603, a spring 604 and a discharging port 605.

[0039] Specifically, the discharging pipeline 601 is fixedly installed on the outside of the fixed vertical plate 2 on one side of the output end of the main pipeline 1. The input end of the discharging pipeline 601 is connected to the output end of the filter mesh cylinder 502. The pipeline inspection cover 602 is threadedly connected to the end of the discharging pipeline 601 away from the main pipeline 1. Both the sealing pipe plug 603 and the spring 604 are located inside the discharging pipeline 601.

[0040] One end of the spring 604 is fixed to the sealing pipe plug 603, and the other end is fixed to the pipeline inspection cover 602. The discharging port 605 is opened at the bottom of the discharging pipeline 601. A screwing block 11 is fixedly connected to the outside of the pipeline inspection cover 602.

[0041] Furthermore, a control box 8 is arranged at the control end of the driving motor 7. The bottom end of the fixed vertical plate 2 is fixedly connected with a device base 9. The bottom end of the device base 9 is fixedly connected with an anti-slip pad 10. The control box 8 is fixedly connected to the top of the anti-slip pad 10. A limiting groove 12 is opened in the inner cavity of the fixed vertical plate 2. The fixed ring 503 is fixedly connected with a limiting block 13, and the limiting block 13 is movably inserted into the inner cavity of the limiting groove 12.

[0042] During use, the operation of the driving motor 7 is controlled by the control box 8. When the solid impurities are conveyed to the inner cavity of the discharging pipeline 601, due to the blockage of the sealing pipe plug 603, the solid impurities accumulate in the inner cavity of the discharging pipeline 601. At the same time, since the spiral blade 505 continuously conveys the solid impurities, pressure is generated, so that the liquid in the original liquid is extruded out and seeps out from the filter mesh cylinder 502. When the pressure of the solid impurities in the spiral blade accumulates to a certain threshold value, the pressure forms a driving force to move the sealing pipe plug 603 outward. The movement of the sealing pipe plug 603 pushes the spring 604 to contract. When the sealing pipe plug 603 moves beyond the discharging port 605, the solid impurities are discharged to the outside of the discharging pipeline 601 through the discharging port 605, so that the solid impurities will not accumulate excessively; when the pressure is lower than the threshold value, the sealing pipe plug 603 is pushed inward by the resilience of the spring 604, so that the sealing pipe plug 603 blocks the discharging port 605 and closes the discharging pipeline 601, and further enables the solid impurities to be squeezed between the sealing pipe plug 603 and the spiral blade 505, realizing solid-liquid separation.

[0043] When it is necessary to repair the sealing plug 603 or the spring 604, turn the wrench to drive the screw block 11 to rotate, thereby separating the pipeline inspection cover 602 from the discharge pipeline 601, and then the sealing plug 603 and the spring 604 can be taken out. When inserting the filter screen cylinder 502, insert the limit block 13 into the inner cavity of the limit groove 12, so that the limit groove 12 limits the limit block 13, achieving the limit of the filter screen cylinder 502 and the fixing ring 503, so that they will not rotate during use. Install this device to the designated position by using bolts to penetrate the device base 9, and install this device vertically or horizontally according to actual needs. The anti-slip pad 10 increases the friction at the bottom of the main pipeline 1 and can buffer slight vibrations.

[0044] In summary, through the coordinated operation of the components of this device, it solves the problem that the existing equipment cannot automatically discharge solid impurities during use, resulting in the need to stop the equipment when cleaning solid impurities, which will reduce work efficiency, and the operation steps are complex, increasing the work load.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
