Description

Technical Field

[0001] This application relates to the field of filtration testing equipment technology, and in particular to a filter rod filtration accuracy testing device. Background Technology

[0002] After high-pressure acid leaching of laterite nickel ore, nickel enters the solution in ionic form, while impurities (such as iron, aluminum, and silicon) remain mixed in the solution as solids. To ensure proper subsequent extraction, filtration is necessary to separate the solids and liquids in the mixed solution and remove impurities. A filter rod, acting as the filtration medium, traps these impurities, resulting in a clear solution rich in nickel ions. The filtration accuracy of the filter rod plays a decisive role in the filtration effect of the mixed solution. Filter rods are purchased commercially, and their filtration accuracy is indicated on the packaging. However, the actual filtration accuracy may differ from the theoretical accuracy. To ensure effective filtration of the mixed solution, the working condition and filtration accuracy of the filter rod must be verified before use.

[0003] In existing technologies, such as the candle filter rod detection system provided by patent 202121083372.7, the filter rod is placed in a detection chamber, and water and a detection medium are supplied into the chamber. A transmittance detection device is installed at the output end of the detection chamber to detect the intensity of transmitted light from the liquid after filtration by the filter rod. When the filter rod deforms, the detection medium will penetrate it. When the detection medium penetrates the filter rod, the intensity of transmitted light from the solution detected by the transmittance detection device will be affected by the change in the amount of detection medium, thereby determining whether the filter rod is deformed and unable to work. However, the above patent can only qualitatively determine whether the filter rod can work normally. It cannot detect the filtration accuracy of the filter rod, and its detection adaptability is low. It only uses a single specification of detection medium to determine whether the filter rod can work normally, and cannot detect filter rods with different filtration accuracies.

[0004] Therefore, there is an urgent need to provide a filter rod filtration accuracy detection device to solve the above-mentioned problems in the existing technology. Utility Model Content

The first storage structure, the second storage structure, and the testing chamber are connected in sequence by a feed pipeline. Water is supplied from the first storage structure to the feed pipeline, and the second storage structure can selectively supply a specific specification of testing media to the feed pipeline. This allows the testing media to mix in the water and be transported to the testing chamber of the testing chamber, where the filter rods filter the mixture of the testing media and water. Simultaneously, a flow rate detector is installed downstream of the detection chamber to detect the flow rate of the solution discharged from the detection chamber. If the flow rate is greater than a predetermined preset value, it indicates that the detection medium in the mixed solution can pass smoothly through the filter rod, and the filtration accuracy of the filter rod is greater than the specification of the detection medium. If the flow rate is less than or equal to the predetermined preset value, it indicates that the detection medium in the mixed solution cannot pass through the filter rod, and the filtration accuracy of the filter rod is less than or equal to the specification of the detection medium. Combined with the second storage structure, a detection medium of a certain specification can be selectively supplied to the feeding pipeline. When the flow rate detected by the flow rate detector switches from a larger value to a smaller value, it indicates that the specification of the current detection medium is the filtration accuracy of that filter rod.

[0050] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0051] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] In the description of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0053] After high-pressure acid leaching of laterite nickel ore, nickel enters the solution in ionic form, while impurities (such as iron, aluminum, and silicon) remain mixed in the solution as solids. To ensure proper subsequent extraction, filtration is necessary to separate the solids and liquids in the mixed solution and remove impurities. A filter rod, acting as the filtration medium, traps these impurities, resulting in a clear solution rich in nickel ions. The filtration accuracy of the filter rod plays a decisive role in the filtration effect of the mixed solution. Filter rods are purchased commercially, and their filtration accuracy is indicated on the packaging. However, the actual filtration accuracy may differ from the theoretical accuracy. To ensure effective filtration of the mixed solution, the working condition and filtration accuracy of the filter rod must be verified before use. For example, patent 202121083372.7 provides a filter rod detection system for a candle filter. This system places the filter rod in a detection chamber and supplies water and a detection medium into the chamber. A transmittance detection device is installed at the output end of the detection chamber. This device detects the intensity of transmitted light through the liquid after filtration. When the filter rod deforms, the detection medium penetrates it. The intensity of transmitted light detected by the transmittance detection device is affected by the amount of detection medium, thus determining whether the filter rod is deformed and unable to function. However, this patent only qualitatively determines whether the filter rod can function properly. It cannot detect the filtration accuracy of the filter rod and has low adaptability, using only a single type of detection medium to determine if the filter rod can function properly, failing to detect filter rods with different filtration accuracies.

[0054] To solve the above problems, such as Figure 1 As shown, this embodiment provides a filter rod filtration accuracy testing device. The filter rod filtration accuracy testing device includes a first storage structure 100, a second storage structure 200, a testing chamber 300, a feed pipeline, and a flow rate detection element 700. The first storage structure 100 stores water, the second storage structure 200 stores various specifications of testing media, the testing chamber 300 has a testing cavity for accommodating filter rods, and the feed pipeline sequentially connects the first storage structure 100, the second storage structure 200, and the testing chamber 300. The first storage structure 100 is configured to supply water to the feed pipeline, and the second storage structure 200 can selectively supply a specific specification of testing media to the feed pipeline. The flow rate detection element 700 is installed on the feed pipeline and located downstream of the testing chamber 300, and is used to detect the flow rate of the solution discharged from the testing chamber 300.

[0055] This filter rod filtration accuracy testing device comprises a first storage structure 100 for storing water, a second storage structure 200 for storing various specifications of testing media, and a testing chamber 300 for housing filter rods. A feed pipeline connects the first storage structure 100, the second storage structure 200, and the testing chamber 300 sequentially. Water is supplied from the first storage structure 100 into the feed pipeline, and the second storage structure 200 can selectively supply a specific specification of testing media into the feed pipeline. This allows the testing media to mix with the water and be transported to the testing chamber 300. The filter rods in the testing chamber filter the mixture of testing media and water, while simultaneously... A flow rate detector 700 is installed downstream to detect the flow rate of the solution discharged from the detection chamber 300. If the flow rate is greater than a predetermined preset value, it indicates that the detection medium in the mixed solution can pass smoothly through the filter rod, and the filtration accuracy of the filter rod is greater than the specification of the detection medium. If the flow rate is less than or equal to the predetermined preset value, it indicates that the detection medium in the mixed solution cannot pass through the filter rod, and the filtration accuracy of the filter rod is less than or equal to the specification of the detection medium. Combined with the second storage structure 200, a detection medium of a certain specification can be selectively supplied to the feeding pipeline. When the flow rate detected by the flow rate detector 700 switches from a larger value to a smaller value, it indicates that the specification of the current detection medium is the filtration accuracy of that filter rod. This filter rod filtration accuracy detection device not only realizes the detection of the filtration accuracy of the filter rod, but also can detect filter rods with different filtration accuracy, meeting the filtration accuracy detection needs of different filter rods.

[0056] It should be noted that in this embodiment, the detection medium is diatomaceous earth. In other embodiments, the specific type of detection medium can be adjusted according to actual needs; this embodiment does not impose any specific limitations.

[0057] Furthermore, in this embodiment, the preset value set for the flow rate detection element 700 is 6 L / min. If the actual detected solution flow rate is greater than the specified 6 L / min, it indicates that the detection medium in the mixed solution can pass smoothly through the filter rod, and the filtration accuracy of the filter rod is greater than the specifications of the detection medium. If the flow rate is less than or equal to the specified 6 L / min, it indicates that the detection medium in the mixed solution cannot pass through the filter rod, and the filtration accuracy of the filter rod is less than or equal to the specifications of the detection medium. In other embodiments, the preset value set for the flow rate detection element 700 can also be adjusted according to actual needs.

[0058] Optionally, the filter rod filtration accuracy testing device also includes a multi-stage filtration structure 600, wherein the multi-stage filtration structure 600 is installed on the feed pipeline and located between the testing chamber 300 and the second storage structure 200. The multi-stage filtration structure 600 has filter screens of various specifications, each specification of filter screen is set to correspond to a specification of testing medium. The multi-stage filtration structure 600 can selectively switch a filter screen of a certain specification to the working state. The filter screen in the working state is used to filter impurities larger than the corresponding specification of testing medium. By setting up a multi-stage filtration structure 600 with various sizes of filter screens, the multi-stage filtration structure 600 is installed on the feed pipeline and positioned between the detection chamber 300 and the second storage structure 200. Depending on the specifications of the detection medium, one type of filter screen within the multi-stage filtration structure 600 can be selectively switched to the working state. This allows filtration to be performed before the mixed solution of the detection medium and water enters the detection chamber 300, intercepting impurities larger than the corresponding size of the detection medium. This ensures that only the detection medium and impurities smaller than the detection medium enter the detection chamber, solving the problem of impurities larger than the corresponding size of the detection medium affecting the detection accuracy of the filter rod and guaranteeing the detection effect of the filter rod. It should be noted that, in this embodiment, the multi-stage filtration structure 600 includes an installation body and multiple filter screens of various sizes. Each filter screen can be detached and fixed inside the installation body. The installation body is installed on the feed pipeline. When the installation body is installed on the feed pipeline, the filter screens block the transmission path of the feed pipeline. The solution transmitted by the feed pipeline must pass through the filter screens to flow into the detection chamber 300. In actual operation, only the required size filter screen is installed inside the installation body. If the size of the filter medium is changed, the original filter screen inside the installation body needs to be disassembled and a matching filter screen installed.

[0059] In an optional embodiment, the filter rod filtration accuracy detection device further includes a collection element 800, which is installed on the feed pipeline and located downstream of the flow rate detection element 700. The collection element 800 is configured to filter and collect all specifications of the detection medium. By placing the collection element 800 on the feed pipeline and downstream of the flow rate detection element 700, the collection element 800 filters and collects all specifications of the detection medium. After the flow rate detection element 700 has detected the flow rate of the solution, it can intercept all the detection medium in the solution, thus achieving the recycling of the detection medium. It should be noted that in this embodiment, the collection element 800 is a filter cloth, which filters all specifications of the detection medium.

[0060] In addition, the feeding pipeline includes a first pipeline 400 and a second pipeline 500. The two axial ends of the first pipeline 400 are connected to the output end of the first storage structure 100 and the input end of the detection chamber 300, respectively. The second storage structure 200 is installed on the first pipeline 400. The two axial ends of the second pipeline 500 are connected to the output end of the detection chamber 300 and the input end of the first storage structure 100, respectively. The multi-stage filtration structure 600 is installed on the first pipeline 400 and located between the second storage structure 200 and the detection chamber 300. The flow rate detection element 700 and the collection element 800 are sequentially installed on the second pipeline 500. By connecting the two axial ends of the first pipeline 400 to the output end of the first storage structure 100 and the input end of the detection chamber 300 respectively, and connecting the two axial ends of the second storage structure 200 to the output end of the detection chamber 300 and the input end of the first storage structure 100 respectively, the solution containing water and detection medium can be circulated in the feed pipeline. Combined with the filtration and collection of the detection medium by the collection device 800, the water can be returned to the first storage structure 100, realizing the reuse of water.

[0061] As an optional solution, the first pipeline 400 has a first drain branch 410 and a first control valve 420. The first control valve 420 is installed on the first drain branch 410 and is used to control the opening and closing of the first drain branch 410. The second pipeline 500 has a second drain branch 510 and a second control valve 520. The second control valve 520 is installed on the second drain branch 510 and is used to control the opening and closing of the second drain branch 510. By setting the first drain branch 410 in the first pipeline 400 and setting the first control valve 420 to control the opening and closing of the first drain branch 410, the solution in the first pipeline 400 can be quickly discharged when cleaning is required, thereby improving the subsequent cleaning efficiency of the first pipeline 400. By setting a second drain branch 510 in the second pipeline 500 and a second control valve 520 to control the opening and closing of the second drain branch 510, when the second pipeline 500 needs to be cleaned, the second control valve 520 opens the second drain branch 510, which can quickly drain the solution in the second pipeline 500, thereby improving the subsequent cleaning efficiency of the second pipeline 500.

[0062] It should be noted that in this embodiment, both the first control valve 420 and the second control valve 520 are solenoid valves. Solenoid valves have a simple structure, are easy to operate, and are highly responsive. In other embodiments, the first control valve 420 and the second control valve 520 can also be manual valves; this embodiment does not impose any specific limitations.

[0063] In other embodiments, the first drain branch 410 and the first control valve 420 may only be provided in the first pipeline 400. With only the first drain branch 410 and the first control valve 420 provided, when the second pipeline 500 needs cleaning, the solution in the second pipeline 500 is reverse-flowed back to the first pipeline 400 and discharged along the first drain branch 410. Alternatively, the second drain branch 510 and the second control valve 520 may only be provided in the second pipeline 500. With only the second drain branch 510 and the second control valve 520 provided, when the first pipeline 400 needs cleaning, the solution in the first pipeline 400 flows to the second pipeline 500 and is discharged along the second drain branch 510.

[0064] In an optional embodiment, the first storage structure 100 includes a first storage chamber 110, a first conveying branch 120, and a first drive pump 130. The first storage chamber 110 is used to store water. The input end of the first storage chamber 110 is connected to the output end of the second pipeline 400. The two axial ends of the first conveying branch 120 are respectively connected to the output end of the first storage chamber 110 and the input end of the first pipeline 400. The first drive pump 130 is installed on the first conveying branch 120 and is used to drive the water in the first storage chamber 110 to flow into the first pipeline 400 along the first conveying branch 120. By setting up a first conveying branch 120, with its axial ends connected to the output end of the first storage chamber 110 and the input end of the first pipeline 400 respectively, and installing a first drive pump 130 on the first conveying branch 120, the water stored in the first storage chamber 110 is driven by the first drive pump 130 to flow into the first pipeline 400 along the first conveying branch 120, thus meeting the water driving requirements. By connecting the output end of the second pipeline 500 to the input end of the first storage chamber 110, the water filtered by the collected component 800 can be returned to the first storage chamber 110, realizing the reuse of water.

[0065] Optionally, the first storage structure 100 includes a third control valve 140, which is installed on the first conveying branch 120. The third control valve 140 is used to control the opening and closing of the first conveying branch 120. By installing the third control valve 140 on the first conveying branch 120 and controlling its opening and closing, the water in the first storage chamber 110 can be controlled to flow into the first pipeline 400 along the first conveying branch 120. The flow of water into the first pipeline 400 can be freely controlled according to actual needs, improving operational safety. It should be noted that in this embodiment, the third control valve 140 is a solenoid valve. Solenoid valves have a simple structure, are easy to operate, and are highly responsive. In other embodiments, the third control valve 140 can also be a manual valve; this embodiment does not impose a specific limitation.

[0066] In addition, the first storage structure 100 also includes a first replenishment branch 150, which is connected to the first storage chamber 110 and configured to connect to the output end of an external water replenishment device. By setting up the first replenishment branch 150 connected to the first storage chamber 110 and connected to the output end of the external water replenishment device, when the water volume in the filter rod filtration accuracy detection device is insufficient, water can be replenished to the first storage chamber 110 through the first replenishment branch 150, ensuring the normal operation of the filter rod filtration accuracy detection device.

[0067] As an optional solution, the second storage structure 200 includes multiple independent storage units 210. Each storage unit 210 includes a second storage chamber 211, a second conveying branch 212, and a second drive pump 213. The second storage chamber 211 in each storage unit 210 stores a test medium of a certain specification. The two axial ends of the second conveying branch 212 are respectively connected to the second storage chamber 211 and the first pipeline 400. The second drive pump 213 is installed on the second conveying branch 212 and is used to drive the test medium in the second storage chamber 211 to flow into the first pipeline 400 along the second conveying branch 212. By setting multiple independent storage units 210 within the second storage structure 200, and providing a second storage chamber 211 within each storage unit 210, each storage chamber 211 stores a specific type of detection medium. A second conveying branch 212 is provided, with its axial ends connected to the second storage chamber 211 and the first pipeline 400, respectively. A second drive pump 213 is installed on the second conveying branch 212, driving the detection medium in the second storage chamber 211 to flow into the first pipeline 400 along the second conveying branch 212, thus achieving the driving of the detection medium. Understandably, to prevent water in the first pipeline 400 from flowing back into the second storage chamber 211 along the second conveying branch 212, the second storage chamber 211 is located above the first pipeline 400.

[0068] It should be noted that, in this embodiment, the second storage structure 200 includes six independent storage units 210, and the second storage chambers 211 within the six storage units 210 respectively store detection media with diameters of 0.06mm, 0.08mm, 0.10mm, 0.12mm, 0.14mm, and 0.16mm. Furthermore, the multi-stage filtration structure 600 provided in this embodiment has six sizes of filter screens, with filtration specifications corresponding to 0.06mm, 0.08mm, 0.10mm, 0.12mm, 0.14mm, and 0.16mm respectively. In other embodiments, the specific number of storage units 210 within the second storage structure 200, the specific specifications of the detection media stored in each storage unit 210, and the specific specifications of the filter screens within the multi-stage filtration structure 600 can be adjusted according to actual needs. This embodiment does not impose specific limitations on these adjustments.

[0069] Optionally, each storage unit 210 further includes a fourth control valve 214, which is installed on the second conveying branch 212 and is used to control the opening and closing of the second conveying branch 212. By setting the fourth control valve 214 on the second conveying branch 212 to control the opening and closing of the first conveying branch 120, the detection medium in the second storage chamber 211 can be controlled to flow into the first pipeline 400 along the second conveying branch 212. The flow of water into the first pipeline 400 can be freely controlled according to actual needs, improving operational safety. It should be noted that in this embodiment, the fourth control valve 214 is a solenoid valve. Solenoid valves have a simple structure, are easy to operate, and are highly responsive. In other embodiments, the fourth control valve 214 can also be a manual valve; this embodiment does not impose a specific limitation.

[0070] In addition, each storage unit 210 also includes a second replenishment branch 215, which is connected to the corresponding second storage chamber 211 and configured to interface with the output of an external replenishment device. By providing a second replenishment branch 215 connected to the second storage chamber 211 and interfaced with the output of an external replenishment device, replenishment of the detection medium can be achieved.

[0071] In this embodiment, since the detection medium is diatomaceous earth, each second storage chamber 211 is equipped with a desiccant to ensure the dry storage of the diatomaceous earth.

[0072] In an optional embodiment, the filter rod filtration accuracy testing device further includes an indicator component and a controller. The indicator component includes a rotating pointer and an indicator plate. The rotating pointer is rotatably mounted above the indicator plate, which has a first area and a second area. Both the flow rate detector 700 and the rotating pointer are communicatively connected to the controller. When the flow rate detected by the flow rate detector 700 is greater than a preset value, the rotating pointer points to the first area; when the flow rate detected by the flow rate detector 700 is less than or equal to the preset value, the rotating pointer points to the second area. By additionally setting the indicator component and the controller, the rotating pointer within the indicator component is rotatably mounted on the indicator plate, which has a first area and a second area. Both the rotating pointer and the flow rate detector 700 are communicatively connected to the controller. When the flow rate detected by the flow rate detector 700 is greater than the preset value, the controller controls the rotating pointer to point to the first area; when the flow rate detected by the flow rate detector 700 is less than or equal to the preset value, the controller controls the rotating pointer to point to the second area. Operators can quickly determine whether the flow rate detected by the flow rate detector 700 has changed by observing the direction of the rotating pointer.

[0073] To facilitate observation of the position pointed to by the rotating pointer, the first and second regions are different colors. It should be noted that in this embodiment, the first region is green and the second region is red. In other embodiments, the colors of the first and second regions can be adjusted according to actual needs; this embodiment does not impose specific limitations.
