Description

Technical Field

[0001] This invention relates to the field of mineral processing and solid-liquid separation equipment technology, specifically to a fine viscous mineral filtration device to prevent mud runoff. Background Technology

[0002] In experiments involving the purification of fine clay minerals and related mineral processing, vacuum filtration is a commonly used solid-liquid separation method. However, for fine clay mineral systems such as kaolinite and clay minerals, due to their small particle size, fine clay minerals are prone to enter the vacuum system with the filtrate during vacuum filtration, a phenomenon known as "mud runoff."

[0003] Sludge spillage not only causes sample loss, but also contaminates pipelines, affects the normal function of anti-backflow bottles, and in severe cases, can even enter the vacuum pump, causing equipment damage.

[0004] Existing filtration systems typically only use a Buchner funnel, a filtration flask, and a subsequent air extraction device for connection, lacking a dedicated trapping structure for fine particles. While some experimental systems incorporate a simple trapping bottle between the filtration flask and the vacuum pump, uneven airflow distribution leads to significant impact on the filter surface, resulting in poor particle trapping. Furthermore, the fixed internal components make sediment cleaning and component replacement inconvenient, failing to meet the requirement of preventing mud runoff during the filtration of fine, viscous minerals.

[0005] Therefore, there is an urgent need to develop a fine-grained mineral filtration device to prevent mud from flowing away. Summary of the Invention

[0006] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a fine viscous mineral filtration device to prevent mud from running off.

[0007] The objective of this invention can be achieved through the following technical solutions: A fine-viscosity mineral filtration device to prevent sludge runoff, comprising: Buchner funnel, suction flask, collection tube, anti-backflow bottle, and vacuum pump; The Buchner funnel is connected to the filtration flask, and the suction port of the filtration flask is connected in sequence to the collection tube, the anti-backflow bottle and the vacuum pump through pipelines. The collection tube includes a shell, a flow guide, a filter assembly, a collection chamber, and an end cap. The shell has an inlet and an outlet on both sides. The inlet is connected to the suction port of the filtration bottle through a pipe, and the outlet is connected to the anti-backflow bottle through a pipe. The flow guide is located on the inlet side of the shell. The filter assembly is located inside the shell. The collection chamber is located at the bottom of the shell. One side of the filter assembly is connected to the flow guide, and the other side is connected to the outlet. The end cap is detachably connected to the collection tube. The outlet is located on the end cap, and the filter assembly is connected to the end cap.

[0008] As a further aspect of the present invention: the filtration assembly includes a support layer, a microporous membrane sleeved inside the support layer, and a flow guiding layer disposed outside the support layer; a flow guiding gap is left between the support layer and the flow guiding layer, and the microporous membrane includes a cylindrical membrane and a sheet membrane located inside the cylindrical membrane near the outlet side.

[0009] As a further aspect of the present invention: the flow guide includes at least three annularly distributed flow guide plates, the flow guide plates are inclined, both sides of a single flow guide plate are connected to adjacent flow guide plates, and the multiple flow guide plates form a first flow guide channel, the first flow guide channel being aligned with the inner side of the microporous membrane.

[0010] As a further embodiment of the present invention: a support ring is sandwiched between the support layer and the flow guiding layer, and a clamping ring is sleeved on the outer ring of the support layer. Two support rings and two clamping rings are provided, and the two support rings and the two clamping rings are respectively provided at both ends of the flow guiding layer.

[0011] As a further aspect of the present invention: the support layer has multiple through holes, which are distributed in an equally spaced array.

[0012] As a further aspect of the present invention: the flow guiding layer is provided with a plurality of second flow guiding channels, and the plurality of second flow guiding channels are distributed in an array at equal intervals.

[0013] As a further embodiment of the present invention: the end cap is threaded or snapped into the collecting cylinder.

[0014] As a further aspect of the present invention: a discharge port is provided at the bottom of the collection chamber, and a discharge cover is detachably installed on the discharge port.

[0015] As a further aspect of the present invention: the collection tube is a horizontally arranged columnar structure, and the filter assembly is horizontally arranged inside the collection tube.

[0016] As a further aspect of the present invention, the collection tube is transparent.

[0017] The beneficial effects of this invention include, but are not limited to: By placing the guide component on the inlet side of the housing, this invention rectifyes the airflow and fluid carrying fine particles entering the collection cylinder, preventing them from directly impacting the filter surface, thereby protecting the filter assembly and improving particle interception efficiency. Furthermore, by placing the filter assembly inside the housing, the rectified mixture is filtered, with fine particles intercepted and retained within the filter assembly, while clean gas is discharged through the outlet to the anti-backflow bottle and then drawn away by a vacuum pump. This effectively prevents fine, sticky minerals from entering subsequent equipment and causing contamination and damage. In addition, the collection chamber is located at the bottom of the housing, utilizing gravity to collect the intercepted liquid, achieving centralized sedimentation and temporary storage of the liquid.

[0027] See Figures 1-2 An embodiment of the present invention provides a fine viscous mineral filtration device to prevent mud spillage, comprising: a Buchner funnel 1, a filtration flask 2, a collection cylinder 3, an anti-backflow bottle 4, and a vacuum pump 5; the Buchner funnel 1 is connected to the filtration flask 2, and the suction port of the filtration flask 2 is connected to the collection cylinder 3, the anti-backflow bottle 4, and the vacuum pump 5 in sequence via pipelines; the collection cylinder 3 includes a shell 31, a flow guide 32, a filter assembly 33, a collection chamber 34, and an end cap 35; the shell 31 has an inlet 311 and an outlet 312 on both sides, the inlet... 311 is connected to the suction port of the filtration bottle 2 through a pipeline, and the outlet 312 is connected to the anti-backflow bottle 4 through a pipeline. The guide 32 is located on the inlet 311 side of the housing 31. The filter assembly 33 is located inside the housing 31. The collection chamber 34 is located at the bottom of the housing 31. One side of the filter assembly 33 is connected to the guide 32, and the other side is connected to the outlet 312. The end cap 35 is detachably connected to the collection tube 3. The outlet 312 is located on the end cap 35, and the filter assembly 33 is connected to the end cap 35.

[0028] Specifically, during the filtration of fine viscous minerals, the slurry to be filtered is first poured into the Buchner funnel 1. The vacuum pump 5 is then started to create a negative pressure in the filtration bottle 2, the collection cylinder 3, and the anti-backflow bottle 4. Under the negative pressure, the airflow carries some of the fluid carrying fine particles into the collection cylinder 3. The guide 32 is located on the inlet 311 side of the shell 31 to rectify the incoming mixture and prevent the airflow from carrying some of the fluid carrying fine particles from directly impacting the filter surface. Subsequently, the mixture enters the filter assembly 33, where the fine particles are intercepted. The clean gas is discharged through the outlet 312 to the anti-backflow bottle 4 and then drawn away by the vacuum pump 5. The intercepted liquid falls into the collection chamber 34 under gravity, while the intercepted particles remain in the filter assembly 33. When it is necessary to clean, maintain, or replace the filter assembly 33, the end cap 35 is removed to take out the filter assembly 33 for cleaning and replacement.

[0029] In this embodiment, the guide member 32 is disposed on the inlet 311 side of the housing 31 to rectify the airflow and fluid carrying fine particles entering the collection cylinder 3, preventing them from directly impacting the filter surface, thereby protecting the filter assembly 33 and improving particle interception efficiency. Furthermore, the filter assembly 33 is disposed inside the housing 31 to filter the rectified mixture. Fine particles are intercepted and remain within the filter assembly 33, while clean gas is discharged through the outlet 312 to the anti-backflow bottle 4, and then drawn away by the vacuum pump 5. This effectively prevents fine, sticky minerals from entering subsequent equipment and causing contamination and damage. In addition, the collection chamber 34 is located at the bottom of the housing 31, and the intercepted liquid is collected by gravity to achieve centralized sedimentation and temporary storage of the liquid. The device also allows the end cap 35 to be detachably mounted on the collection cylinder 3, with the outlet 312 located on the end cap 35 and the filter assembly 33 connected to the end cap 35. When it is necessary to clean, maintain or replace the filter assembly 33, the filter assembly 33 can be removed as a whole by removing the end cap 35, which is convenient to operate. Through the cooperation of the above structures, the collection efficiency of fine particles is improved and the maintenance operation of the fine sticky mineral filtration and anti-sludge device is simplified.

[0030] See Figures 3-5 Optionally, the filter assembly 33 includes a support layer 331, a microporous membrane 332 sleeved inside the support layer 331, and a flow guiding layer 333 disposed outside the support layer 331; the support layer 331 is used to provide support for the microporous membrane 332, and a flow guiding gap 334 is left between the support layer 331 and the flow guiding layer 333 to allow the filtered fluid to pass through; the microporous membrane 332 includes a cylindrical membrane 332a and a sheet membrane 332b located inside the cylindrical membrane 332a near the outlet 312.

[0031] In this embodiment, during the filtration process, the airflow carrying the fluid containing fine particles enters the filter assembly 33 and first contacts the filter membrane. Most of the liquid and fine particles fall onto the filter membrane due to gravity. The liquid passes through the microporous membrane 332 and falls through the support layer 331 and the guide layer 333, converging into the collection chamber 34. Fine particles cannot pass through the microporous membrane 332 and are retained inside the microporous membrane 332. A small portion of the mixed fluid moves with the airflow to the end of the filter assembly 33 and is intercepted by the sheet-like microporous membrane 332. The liquid seeps out through the microporous membrane 332, while the fixed particles remain inside the microporous membrane 332. The user can use the end cap 35 to periodically disassemble the filter assembly 33 and clean, maintain, or replace it.

[0032] See Figure 2 Optionally, the flow guide 32 includes at least three annularly distributed flow guide plates 321. The flow guide plates 321 are inclined. Both sides of a single flow guide plate 321 are connected to adjacent flow guide plates 321. The multiple flow guide plates 321 form a first flow guide channel 322, which is aligned with the inner side of the microporous membrane 332.

[0033] In this embodiment, multiple guide plates 321 are arranged in a ring and tilted to form a pyramidal first guide channel 322, which gathers the airflow and makes it enter the filter assembly 33 more evenly, avoiding the airflow directly impacting the surface of the microporous membrane 332 and causing it to be excessively worn locally or penetrated by particles.

[0034] See Figures 3-5 Optionally, a support ring 335 is sandwiched between the support layer 331 and the flow guiding layer 333, and a clamping ring 336 is sleeved on the outer ring of the support layer 331. Two support rings 335 and two clamping rings 336 are provided, and the two support rings 335 and the two clamping rings 336 are respectively provided at both ends of the flow guiding layer 333.

[0035] In this embodiment, the support ring 335 is sandwiched between the support layer 331 and the flow guiding layer 333 to position and space the support layer 331 and the flow guiding layer 333, ensuring that a stable flow guiding gap 334 is maintained between the two. The clamping ring 336 is sleeved on the outer ring of the support layer 331 to fix the relative position of the support layer 331 and the flow guiding layer 333, preventing them from being displaced or deformed under negative pressure. In addition, the support ring 335 and the clamping ring 336 are respectively disposed at both ends of the flow guiding layer 333 to constrain both ends of the filter assembly 33 as a whole.

[0036] See Figures 3-4 Optionally, the support layer 331 has multiple through holes 331a arranged in an equally spaced array. This arrangement provides a uniform and unobstructed passage path for the liquid. Furthermore, the array distribution of the through holes 331a facilitates uniform negative pressure transmission, preventing excessive local pressure differences in the filter assembly 33 from causing damage to the microporous membrane 332 or particle penetration. See Figures 2-4 Optionally, the flow guiding layer 333 is provided with multiple second flow guiding channels 333a, which are distributed in an equally spaced array. Liquid falls from the through hole 331a into the flow guiding gap 334 and then enters the second flow guiding channel 333a, which facilitates the passage of liquid and also facilitates the subsequent rinsing of the filter assembly 33.

[0037] See Figures 1-2 Optionally, the end cap 35 is threaded or snapped into the collection cylinder 3. When it is necessary to disassemble the filter assembly 33, the operator only needs to manually twist or press the buckle to quickly remove the end cap 35 and pull the filter assembly 33 out of the collection cylinder 3.

[0038] See Figure 2Optionally, a discharge port 341 is provided at the bottom of the collection chamber 34, and a discharge cover 342 is detachably installed on the discharge port 341. When the liquid in the collection cylinder 3 reaches a certain height, the operator opens the discharge cover 342, and the liquid flows into the external collection device through the discharge port 341, thus avoiding local accumulation of liquid in the filter assembly 33.

[0039] See Figures 1-2 Optionally, the collection tube 3 is a horizontally arranged columnar structure, and the filter assembly 33 is horizontally arranged inside the collection tube 3. The horizontal structure makes it easy for the liquid to drip evenly downward into the collection chamber 34 under the action of gravity, thus avoiding local accumulation of liquid in the filter assembly 33.

[0040] See Figures 2-4 Optionally, the collection tube 3 is transparent, which allows users to observe the working status inside the collection tube 3 in real time, including the airflow, whether there is obvious blockage on the surface of the filter component 33, and the amount of liquid accumulation inside the collection tube 3, so that users can promptly detect abnormalities inside the collection tube 3.

[0041] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
