Description

Technical Field

[0001] This application belongs to the technical field of liquid removal equipment, and in particular relates to a concentrator. Background Technology

[0002] In industrial production, a concentrator is a type of desolventizing machine. Concentrators are typically used to remove solvent from solutions, thereby concentrating the solution.

[0003] After prolonged operation, the filtration performance of the filter structure decreases, posing a risk of filter structure failure. This can cause liquid to carry solid particles into the filter structure, resulting in material loss. Summary of the Invention

[0004] This application provides a thickener to solve the technical problem of material loss caused by the failure of the filter structure in existing thickeners.

[0005] According to one aspect of this application, a concentrator is provided, including a first container assembly, a second container assembly, and a pipe connection structure; the first container assembly includes a filter structure; the first container assembly and the second container assembly are spaced apart; the pipe connection structure is disposed between the first container assembly and the second container assembly and communicates with the first container assembly and the second container assembly, the filter structure is connected to the pipe connection structure, and at least a portion of the pipe connection structure is a transparent pipe to observe the fluid state in the pipe connection structure.

[0006] The thickener includes a first container assembly, a second container assembly, and a pipe connection structure. The first container assembly includes a filter structure. The first and second container assemblies are connected by a pipe connection structure located between them. The filter structure is also connected to the pipe connection structure. Thus, the filter structure within the first container assembly can separate the fluid within the first container assembly from other materials, allowing the fluid to enter the filter structure. This enables the fluid in both the first and second containers to flow through the pipe connection structure. The pipe connection structure has a transparent section. Operators can determine if the fluid in the transparent section has changed from a normal operating state to an abnormal operating state—for example, from transparent to cloudy, or from colorless to another color—by observing that the thickener's filter structure has failed, and can then take timely protective measures to avoid material loss.

[0007] In an optional embodiment of this application, the pipe connection structure includes a plurality of spaced-apart connecting pipes, at least a portion of which is a transparent pipe; the first container assembly also includes a first tank, and the filtration structure includes a plurality of filter rods spaced apart in the first tank, each filter rod being connected to at least one connecting pipe to communicate with the second container assembly.

[0008] In an optional embodiment of this application, the pipeline connection structure further includes a control valve, which is installed in each connecting pipeline and used to control the on / off state within the connecting pipeline.

[0009] In an optional embodiment of this application, the control valve on one of two adjacent connecting pipes is axially offset from the control valve on the other connecting pipe.

[0011] In an optional embodiment of this application, the first adapter structure includes a first adapter plate and a plurality of first adapters, the plurality of first adapters passing through the first adapter plate along the axial direction of the connecting pipe; the second adapter structure includes a second adapter plate and a plurality of second adapters, the plurality of second adapters passing through the second adapter plate along the axial direction of the connecting pipe; the plurality of first adapters and the plurality of second adapters are arranged facing each other, and each connecting pipe is connected to the first adapters and second adapters facing each other.

[0012] In an optional embodiment of this application, a support structure is also included. The support structure is connected to the first container assembly and the second container assembly, and the support structure is disposed between the first container assembly and the second container assembly to enclose and form an observation area. The pipeline connection structure is located within the observation area.

[0013] In an optional embodiment of this application, the support structure includes a first ring plate, a second ring plate, and multiple support rods; at least a portion of the first ring plate is located on the side of the first container assembly facing the second container assembly, and at least a portion of the second ring plate is located on the side of the second container assembly facing the first container assembly; the multiple support rods are spaced apart circumferentially along the first container assembly, and one end of each support rod is connected to the first container assembly and the first ring plate, and the other end is connected to the second container assembly and the second ring plate.

[0014] Understandably, the observation area formed by the support structure and the first and second container assemblies is a non-enclosed space. The support rods are spaced apart along the circumference of the first container assembly to facilitate the opening and closing of the control valves on the connecting pipes and to facilitate the replacement of the transparent pipes.

[0015] In the optional scheme of this application, a control module and multiple optical sensors are also included. Each connecting pipe is equipped with a corresponding optical sensor, which is used to monitor the state of the fluid in the connecting pipe. Each optical sensor and each control valve are connected to the control module, which is configured to control the opening and closing of the control valve according to the signal emitted by the optical sensor.

[0016] In an optional embodiment of this application, the first tank is provided with a first liquid outlet and a second liquid outlet, and the second tank is provided with a third liquid outlet; the bottom of the first tank is gradually tapered along the axial direction of the connecting pipe and in a direction away from the second tank, the second liquid outlet is located at the bottom of the first tank, and the first liquid outlet is located above the second liquid outlet.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0034] The thickener provided in this application can be applied to a variety of different application scenarios. For example, in the field of hydrometallurgy, the thickener can be used for dewatering of fine and tailings slurries before filtration, and can also be used for the concentration and purification of solid-containing slurries.

[0035] It should be understood that after prolonged operation, the filtration performance of the thickener's internal filter structure will decrease, leading to material loss. Although the thickener's instruction manual generally indicates the service life of the filter structure, the inventors have discovered that even towards the end of its service life, there is a risk of particle loss from the mother liquor due to reduced filtration performance.

[0036] In this regard, this application provides a concentrator. Figure 1 This is a schematic diagram of a concentrator 1000 provided according to one embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the 1000 condenser from another perspective. Figure 3 This is a partial cross-sectional view of a concentrator 1000 provided according to one embodiment of this application.

[0037] Please see Figures 1 to 3 The concentrator 1000 includes a first container assembly 100, a second container assembly 200, and a pipeline connection structure 300. The first container assembly 100 includes a filtration structure. It should be noted that... Figure 1 and Figure 2 The pipe connection structure 300 is omitted in the illustrated embodiment.

[0038] The first container assembly 100 and the second container assembly 200 are spaced apart. A pipe connection structure 300 is disposed between the first container assembly 100 and the second container assembly 200 and connects the first container assembly 100 and the second container assembly 200. A filter structure is connected to the pipe connection structure 300, and at least a portion of the pipe connection structure 300 is a transparent pipe to facilitate observation of the fluid state in the pipe connection structure 300.

[0039] In this embodiment, both the first container assembly 100 and the second container assembly 200 have sealed spaces formed within them, which can be used to store fluid media. A filter structure within the first container assembly 100 can separate the fluid from other materials within the first container assembly 100, allowing the fluid to enter the filter structure. A pipe connection structure 300 is disposed between the first container assembly 100 and the second container assembly 200 to connect them. The filter structure is connected to the pipe connection structure 300, thus allowing fluid to flow between the first container assembly 100 and the second container assembly 200.

[0040] In particular, the pipe connection structure 300 has a transparent pipe, which allows operators to observe the fluid state in the transparent pipe in order to judge the concentration effect of the concentrator 1000.

[0041] In some specific applications, the concentrator 1000 can be used to concentrate mother liquor containing solid particles. The mother liquor can be a slurry containing solid particles and water. For example, the mother liquor can be a slurry containing pyrolusite or a slurry containing nickel-cobalt-manganese hydroxide. The second container assembly 200 is located above the first container assembly 100. The mother liquor to be concentrated can flow in from the first container assembly 100. The liquid water and solid particles in the mother liquor can be separated by a filtration structure. The second container assembly 200 is connected to a negative pressure device, and under the action of the negative pressure device, the separated liquid water can flow from the first container assembly 100 to the second container assembly 200 through the pipe connection structure 300.

[0042] It should be understood that liquid water is a transparent fluid medium, and its state will change when solid particles are mixed in. In this way, operators can visually observe the state changes of the liquid water in the transparent pipe of the pipe connection structure 300 (such as from transparent to turbid, from colorless to other colors), and determine that solid particles are mixed in the liquid water, so as to take protective measures in time to avoid material loss.

[0043] It should be understood that during the concentration process, if the liquid contains other water-soluble particles, such as sodium ions, chloride ions, iron ions, etc., and the size of the particles is within the pore size range allowed by the filter structure, the particles may also flow from the first container assembly 100 to the second container assembly 200 via the pipe connection structure 300.

[0044] In one alternative embodiment, the pipe connection structure 300 includes a plurality of spaced-apart connecting pipes 310, at least a portion of each connecting pipe 310 being a transparent pipe.

[0045] The filtration structure includes multiple filter rods 120.

[0046] The first container assembly 100 also includes a first tank 110, with a plurality of filter rods 120 spaced apart from each other in the first tank 110. Each filter rod 120 is correspondingly connected to at least one of the connecting pipes 310 to communicate with the second container assembly 200.

[0047] Understandably, each filter rod 120 can be connected to one connecting pipe 310, or each filter rod 120 can be connected to multiple connecting pipes 310, and multiple filter rods 120 can be connected to the same connecting pipe 310.

[0048] In this embodiment, each filter rod 120 extends axially along the connecting pipe 310. Multiple filter rods 120 are combined to form a filtration structure located within the first container assembly 100. The filter rods 120 are configured to allow liquid water in the mother liquor to pass through while blocking solid particles from passing through. That is, the filtration structure formed by multiple filter rods 120 mainly serves to separate the clear liquid.

[0049] The first tank 110 can be used to introduce the mother liquor to be concentrated. The clear liquid is separated by multiple filter rods 120 for concentration. The separated clear liquid enters the second container assembly 200 through the filter rods 120 and connecting pipes 310. Operators can directly observe the color of the transparent pipe part of each connecting pipe 310, which effectively improves the efficiency of manually identifying failed filter rods.

[0050] It is understood that in some embodiments of this application, filter rod failure refers to the situation where, during filter rod operation, materials that were originally not intended to pass through the filter rod can pass through the filter rod due to the deterioration of the filter rod's performance, thus preventing the filter rod from achieving its normal filtration and separation effect.

[0051] It is evident that the first container assembly 100 can concentrate the mother liquor, while the second container assembly 200 mainly serves to retain and buffer the clear liquid.

[0052] In some specific applications, the number of filter rods 120 is the same as the number of connecting pipes 310. After the mother liquor to be concentrated is concentrated by the first container assembly 100, the clear liquid separated by each filter rod 120 needs to pass through the transparent pipe section of a connecting pipe 310 respectively, so that the operator can observe it.

[0053] In some specific applications, the filter rod 120 can be a hollow tube with micropores distributed throughout its wall. These micropores are designed to prevent solute particles from passing through while allowing liquid water to pass through. Of course, the filter rod 120 is not limited to this; for example, it can also be a columnar filter element with multiple filter layers arranged radially inwards and outwards, or it can be a filter ball with filtration function. In short, the filtration structure must be able to separate a clear liquid. It should be noted that the clear liquid here can refer to liquid water or a transparent liquid containing tiny mineral particles.

[0054] The connecting pipe 310 can be a transparent plastic pipe, meaning the entire connecting pipe 310 is a transparent pipe, or a small section of the connecting pipe 310 can be made transparent, with that transparent section corresponding to the transparent pipe part.

[0055] In a further optional embodiment, the pipe connection structure 300 further includes a control valve 320 disposed in each connection pipe 310 and used to control the on / off state within the connection pipe 310.

[0056] In this embodiment, there are multiple control valves 320, the same number as the connecting pipes 310. Each connecting pipe 310 is connected to one control valve 320, and each control valve 320 is used to switch on and off a corresponding connecting pipe 310. Thus, if a mixing phenomenon is observed in a certain connecting pipe 310, the corresponding control valve 320 can be closed in time, preventing material loss due to mixing caused by filter rod 120 failure. Unfailed filter rods can continue to be used, extending the equipment's service life, reducing the frequency of filter rod 120 replacement, and minimizing the reduction in production efficiency caused by filter rod 120 replacement.

[0057] It should be noted that the number of control valves 320 can differ from the number of connecting pipes 310. Multiple connecting pipes can be connected to one control valve 320, allowing one control valve to control multiple connecting pipes 310. For example, when the control valve 320 is a multi-way control valve, it can control the on / off state of multiple connecting pipes 310. In some applications, the control valve 320 can be a manually operated valve, such as a straight-through valve or a ball valve.

[0058] Figure 4 This is a schematic block diagram illustrating an automatic detection function according to one embodiment of this application. Please refer to... Figure 4 In a further optional embodiment, the concentrator 1000 also includes a control module 500 and a plurality of light sensors 600, with each connecting pipe 310 correspondingly provided with a light sensor 600, which is used to monitor the color change of the fluid in the connecting pipe 310.

[0059] Each optical sensor 600 and each control valve 320 are connected to the control module 500. The control module 500 is configured to control the opening and closing of the control valve 320 according to the signal sent by the optical sensor 600.

[0060] In this embodiment, the number of light sensors 600 is the same as the number of connecting pipes 310. Each transparent pipe portion of the connecting pipe 310 is equipped with a corresponding light sensor 600. The light sensor 600 can detect the color of the fluid in the transparent pipe portion of the connecting pipe 310.

[0061] It should be understood that when the fluid medium flowing within the pipe connection structure 300 is liquid water, and the number of connecting pipes 310 in the pipe connection structure 300 is the same as the number of filter rods 120 and they are connected one-to-one, if the transparent pipe portion of a certain connecting pipe 310 is transparent, it indicates that the filtration performance of the corresponding filter rod 120 is normal, and the corresponding control valve 320 remains open. If turbidity occurs in the transparent pipe portion of a certain connecting pipe 310, it indicates that the corresponding filter rod 120 has failed, and the corresponding photosensitive sensor 600 will be triggered to send a signal to the control module 500. The control module 500 will then close the corresponding control valve 320 based on the signal sent by the photosensitive sensor 600.

[0062] In this way, each failed filter rod 120 can be automatically identified in a timely and accurate manner based on the color change of the fluid in each connecting pipe 310, and the corresponding control valve 320 can be closed according to each failed filter rod 120 to avoid material loss and ensure concentration effect.

[0063] In some specific applications, the control module 500 may be, but is not limited to, a general-purpose processor, a special-purpose processor, a conventional processor, a digital signal processor (DSP), multiple microprocessors, one or more microprocessors associated with a DSP core, a controller, a microcontroller, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) circuit, any other type of integrated circuit (IC), and a state machine, etc.

[0064] In this embodiment, the control valve 320 can be an electrically controlled regulating valve, a pneumatic regulating valve, etc. For example, when the control valve 320 is an electrically controlled regulating valve, the control module 500 can send a control signal to the control valve 320 to switch the connecting pipe 310. As another example, when the control valve 320 is a pneumatic regulating valve, the control module 500 can send a control signal to the pneumatic actuator to switch the control valve 320 on and off.

[0065] In some specific applications, the optical sensor 600 can be used as a turbidity sensor, utilizing optical principles to measure the light scattering or absorption caused by suspended particles in a liquid, thereby indirectly determining the turbidity of the liquid. However, it is not limited to this; for example, the optical sensor 600 can also be used as a color sensor, emitting light of a specific wavelength and detecting the intensity and wavelength of light reflected or transmitted through the fluid to determine changes in the fluid's color.

[0066] In some alternative embodiments, the control valve 320 on one of two adjacent connecting pipes 310 is offset from the control valve 320 on the other in the axial direction of the connecting pipe 310.

[0067] In this embodiment, the control valve 320 corresponding to a certain connecting pipe 310 is arranged axially close to the first container assembly 100 of the connecting pipe 310. Then, the control valves 320 corresponding to other connecting pipes 310 adjacent to the connecting pipe 310 can be arranged axially close to the second container assembly 200 of the connecting pipe 310.

[0068] As can be seen, in the pipeline connection structure 300, each control valve 320 is arranged axially offset from the connecting pipeline 310, which makes it easier for operators to quickly find the corresponding control valve 320 and close the control valve 320 in time, reducing the risk of material loss.

[0069] In some alternative embodiments, the first container assembly 100 further includes a first adapter structure 130 disposed in the first tank 110, and each filter rod 120 is connected to a corresponding connecting pipe 310 through the first adapter structure 130.

[0070] The second container assembly 200 includes a second tank body 210 and a second adapter structure 220. The second adapter structure 220 is disposed on the second tank body 210 and is disposed opposite to the first adapter structure 130 in the axial direction of the connecting pipe 310. The connecting pipe 310 is connected to the second tank body 210 via the second adapter structure 220.

[0071] In this embodiment, the pipe connection structure 300 is disposed between the first transition structure 130 and the second transition structure 220, and each connecting pipe 310 in the pipe connection structure 300 is connected between the first transition structure 130 and the second transition structure 220.

[0072] Each connecting pipe 310 is connected at both ends to the first adapter structure 130 and the second adapter structure 220 respectively, so as to connect each filter rod 120 in the first tank 110 to the second tank 210. Each connecting pipe 310 has a transparent pipe portion for observing the color change of the fluid in the pipe to identify the failed filter rod 120.

[0073] In some specific applications, the first adapter structure 130 is disposed at the top of the first tank 110 to seal the first tank 110. The second adapter structure 220 is disposed at the bottom of the second tank 210 to seal the second tank 210. Thus, the first adapter structure 130 and the second adapter structure 220 are arranged axially opposite to each other in the connecting pipe 310.

[0074] In a further optional embodiment, the first adapter structure 130 includes a first adapter plate 131 and a plurality of first adapters 132, the plurality of first adapters 132 passing through the first adapter plate 131 along the axial direction of the connecting pipe 310.

[0075] The second adapter structure 220 includes a second adapter plate 221 and a plurality of second adapters 222, the plurality of second adapters 222 passing through the second adapter plate 221 along the axial direction of the connecting pipe 310.

[0076] Multiple first adapters 132 and multiple second adapters 222 are arranged facing each other, and each connecting pipe 310 is connected to the first adapter 132 and the second adapter 222 facing each other.

[0077] It is understandable that some of the first adapters 132 and some of the second adapters 222 can be set facing each other one-to-one, while the remaining first adapters 132 and the remaining second adapters 222 can be set facing each other at different angles.

[0078] In this embodiment, both the first adapter structure 130 and the second adapter structure 220 are adapter plate structures with multiple adapters fixedly installed. As mentioned above, the first adapter structure 130 and the second adapter structure 220 are arranged opposite each other along the axial direction of the connecting pipe 310. The first adapter 132 can be inserted through the first adapter plate 131 along the axial direction of the connecting pipe 310, and the second adapter 222 can be inserted through the second adapter plate 221 along the axial direction of the connecting pipe 310, so that the first adapter 132 and the second adapter 222 face each other.

[0079] In some specific applications, the number of first adapters 132 and second adapters 222 is the same as the number of connecting pipes 310. The first adapters 132 and second adapters 222 are one-to-one facing each other. The first adapters 132 and second adapters 222 facing each other form a set of adapter pairs for connecting the two ends of a connecting pipe 310 respectively, thereby realizing the connection between each filter rod 120 in the first tank 110 and the second tank 210 via each connecting pipe 310.

[0080] In this embodiment, the clear liquid separated by the filter rod 120 flows into the second tank 210 through the first adapter 132, the connecting pipe 310 and the second adapter 222 in sequence.

[0081] It should be noted that, in Figure 3 In the embodiment shown, the control valve 320 corresponding to the connecting pipe 310 is connected to the first adapter 132 through a fastening connector 301, and the control valves 320 corresponding to other connecting pipes adjacent to the connecting pipe 310 can be connected to the second adapter 222 through another fastening connector 301. In this way, the control valves 320 in two adjacent connecting pipes 310 can be staggered in the axial direction of the connecting pipe 310.

[0082] In some specific applications, both the first adapter plate 131 and the second adapter plate 221 are plates with multiple through holes, through which corresponding adapters can pass to fix the limiting adapters. Both the first adapter 132 and the second adapter 222 can be threaded connectors; specifically, both ends of the adapters are threaded. The fastening connector 301 can be a threaded connector with threaded holes, fixing the filter rod 120, control valve 320, and connecting pipe 310 via a threaded connection. It should be noted that the connecting pipe 310 is generally a flexible hose, facilitating cleaning and replacement of contaminated pipes, and the connection between the connecting pipe 310 and the adapter can be sealed with a nut.

[0083] As can be seen from the foregoing, the first transition structure 130 and the second transition structure 220 also serve to seal the corresponding tanks. Figure 5 For a schematic diagram of an adapter board provided according to one embodiment of this application, please refer to [link / reference]. Figure 5 The first adapter plate 131 and the second adapter plate 221 are provided with sealing rings 700 on their periphery to ensure the sealing of the container assembly.

[0084] Of course, adapters are not limited to threaded connectors. For example, adapters can also be bamboo-joint structure connectors to achieve quick insertion and removal and fixation with the connecting pipe 310.

[0085] In some optional embodiments, the concentrator 1000 further includes a support structure 400 connected to the first container assembly 100 and the second container assembly 200, and the support structure 400 is disposed between the first container assembly 100 and the second container assembly 200 and encloses an observation area, with the pipeline connection structure 300 located within the observation area.

[0086] In this embodiment, the first container assembly 100 and the second container assembly 200 are arranged axially at intervals on the connecting pipe 310 by the support structure 400, and the first container assembly 100 and the second container assembly 200 together form an observation area.

[0087] Specifically, the concentrator 1000 has a three-section layout structure. The support structure 400 is located in the middle and is an open structure, that is, it adopts a non-sealed design, which makes it easy for operators to observe the color change of the fluid in the pipeline connection structure 300 located in the observation area.

[0088] In a further optional embodiment, the support structure 400 includes a first ring plate 410, a second ring plate 420, and a plurality of support rods 430. At least a portion of the first ring plate 410 is located on the side of the first container assembly 100 facing the second container assembly 200, and at least a portion of the second ring plate 420 is located on the side of the second container assembly 200 facing the first container assembly 100.

[0089] Multiple support rods 430 are arranged at intervals along the circumference of the first container assembly 100, and one end of each support rod 430 is connected to the first container assembly 100 and the first ring plate 410, and the other end is connected to the second container assembly 200 and the second ring plate 420.

[0090] In this embodiment, the support structure 400 can be formed by multiple support rods 430 cooperating with a first ring plate 410 and a second ring plate 420 at both ends of the multiple support rods 430. One end of any support rod 430 passes through the first ring plate 410 and is connected to the first container assembly 100, and the other end passes through the second ring plate 420 and is connected to the second container assembly 200. The multiple support rods 430 are arranged at circumferential intervals, and the entire support structure 400 is located between the first container assembly 100 and the second container assembly 200.

[0091] As can be seen, the support structure 400 is an open structure set between the first container assembly 100 and the second container assembly 200 to form an observation area. Operators can observe the changes in the fluid state within the pipe connection structure 300 from the periphery of the support structure 400 in order to switch the control valve 320 on and off.

[0092] exist Figure 3 In the illustrated embodiment, both the peripheral walls of the first tank 110 and the second tank 210 are provided with radially extending lugs to form a first flange 113 and a second flange 212, respectively. A first ring plate 410 is connected to the first flange 113 and, in conjunction with a support rod 430, clamps and fixes the first transition structure 130 between the first ring plate 410 and the first flange 113. A second ring plate 420 is connected to the second flange 212 and, in conjunction with a support rod 430, clamps and fixes the second transition structure 220 between the second ring plate 420 and the second flange 212.

[0093] As can be seen, the support structure 400, in conjunction with the first tank 110 and the second tank 210, secures the first transition structure 130 and the second transition structure 220. In some specific applications, both ends of each support rod 430 are provided with threaded structures, and both the first flange 113 and the second flange 212 are provided with threaded holes spaced apart circumferentially. The threaded structures at both ends of each support rod 430 can be fixedly installed in the threaded holes of the corresponding lugs to connect the ring plate to the lugs on the tank and clamp and fix the transition structure.

[0094] It should be understood that both the first ring plate 410 and the second ring plate 420 adopt a ring structure to avoid the pipe connection structure 300 and ensure that each connecting pipe 310 in the pipe connection structure 300 can be connected to the first transition structure 130 and the second transition structure 220.

[0095] In an alternative embodiment, the two threaded sections of each support rod 430 may also be fitted with nuts to further secure each support rod 430.

[0096] In one alternative embodiment, multiple support rods 430 are arranged at uniform intervals along the circumference of the first container assembly 100. That is, the support rods 430 are arranged at equal intervals, thus providing uniform support for the first container assembly 100 and the second container assembly 200, resulting in better stability of the entire concentrator 1000.

[0097] In some optional embodiments, the first tank 110 is provided with a first liquid outlet 111 and a second liquid outlet 112, and the second tank 210 is provided with a third liquid outlet 211.

[0098] The bottom of the first tank 110 is tapered along the axial direction of the connecting pipe 310 and in a direction away from the second tank 210. The second liquid outlet 112 is located at the bottom of the first tank 110, and the first liquid outlet 111 is located above the second liquid outlet 112.

[0099] In this embodiment, the first liquid outlet 111 is used to introduce the mother liquor to be concentrated. Under the action of a negative pressure device (e.g., a negative pressure pump), the clear liquid is separated into the second tank 210 through the filter rod 120 in the first tank 110 and flows out from the third liquid outlet 211. The concentrated mother liquor is deposited at the bottom of the first tank 110 and can flow out from the second liquid outlet 112.

[0100] The bottom of the first tank 110 is designed to taper in the direction of fluid flow, specifically in the form of a funnel shape. The precipitate (such as solid particles) bears a greater gravitational force in the funnel part, which facilitates the sedimentation and outflow of the concentrated mother liquor and helps to increase the solid content of the outflowing mother liquor.

[0101] In summary, under the action of negative pressure, the concentrator 1000 can transport the clarified liquid separated by the filter rod 120 in the first container assembly 100 to the second container assembly 200. During the transport process, the clarified liquid passes through the pipe connection structure 300, which connects the first container assembly 100 and the second container assembly 200 and has a transparent pipe section. The color change of the liquid water in the transparent pipe section can be observed with the naked eye to determine whether the corresponding filter rod 120 is malfunctioning, effectively improving the efficiency of manually identifying malfunctioning filter rods.

[0102] Furthermore, the mixing phenomenon can be handled by switching control valve 320, effectively avoiding material loss. Moreover, the control valve 320 can be automatically switched on and off, reducing the risk of difficulty in handling mixing phenomena due to untimely human response.

[0103] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
