The casing 110 of the above-described concentration apparatus 100 has a hollow structure, and the shape of the cross section thereof may be circular, square, diamond, etc. The cross-sections of the housing 110 at different locations may be the same size or different sizes. For example, in one embodiment, the housing 110 is a hollow cuboid or cube. In another embodiment, the housing 110 is a hollow cylinder. In yet another embodiment, the housing 110 is a hollow cone. The tank 110 has a slurry inlet 111 at one side for inflow (or input) of slurry to be thickened. The slurry described herein may include slurry, waste material and the like generated in industries such as industry, construction industry and the like, which need to be thickened, and specifically, may include slurry water mixtures containing large particles or small particles such as ore slurry, silt slurry, dust slurry and the like. The slurry inlet 111 is located at one side of the tank 110, and may be implemented by connecting the slurry inlet 111 to one side of the tank 110 in a separate structure form such as a pipe shape, a groove shape, etc., or may be provided according to the structure of the tank 110 itself. For example, in one embodiment, the top edge of one side of the tank 110 can be used as the slurry inlet 111 without additional provision. In another embodiment, a recess is provided in the top of one side of the tank 110 to serve as the slurry inlet 111.

The cone 130 is used to collect thickened mud, which is herein described as solids or slurry that is typically settled at the bottom of the thickener after the mud has been thickened by settling, and may also be referred to as underflow. Since the cone 130 has an inclined surface, the concentrated slurry sinks to the bottom of the cone 130 along the shape of the cone 130 for collection. The bottom of the cone 130 is also connected with an underflow pipe 140, the underflow pipe 140 is also connected with an underflow discharge valve 150, and the opening and closing of the underflow pipe 140 are controlled by the underflow discharge valve 150, so that whether the concentrated mud is discharged or not can be controlled. In one embodiment, the underflow discharge valve 150 may also control the flow rate, pressure, etc. of the fluid in the underflow pipe 140, thereby controlling the discharge rate of the thickened mud, etc.

The concentration device 100 shown in fig. 1a is disposed on a movable chassis 200, and the movable chassis 200 can move the concentration device 100, thereby implementing the movable thickener of the present invention. The concentrator device 100 may be directly or indirectly connected to the movable chassis 200. For example, the concentration device 100 may be connected to the movable base 200 by welding, clamping, screwing, or mounting, or may be directly placed on the movable base 200. In one embodiment, the mobile thickener according to the present invention may further comprise a bracket connected between the thickening apparatus 100 and the mobile chassis 200 for disposing the thickening apparatus 100 on the mobile chassis 200. The location where the thickening apparatus 100 is disposed on the movable chassis 200 may not be limited to the manner of contact with the movable chassis 200 through the underflow pipe 140 shown in fig. 1a, but may be disposed on the movable chassis 200 through other components of the thickening apparatus 100. In one embodiment, the cone 130 of the thickening apparatus 100 is connected to the movable chassis 200, thereby allowing the thickening apparatus 100 to be disposed on the movable chassis 200. In another embodiment, the housing 110 of the concentration device 100 is connected to the movable chassis 200, thereby allowing the concentration device 100 to be disposed on the movable chassis 200. Implementations of the movable chassis 200 may include a variety of, for example, in one embodiment, the movable chassis 200 may be a tracked movable chassis. In another embodiment, the movable chassis 200 may be a wheeled movable chassis.

While the solution and various embodiments of the mobile thickener of the invention have been generally described above in connection with fig. 1a, it should be understood by those skilled in the art that the structure of the mobile thickener shown in fig. 1a is exemplary and not limiting, and those skilled in the art can make modifications to the structure of the thickener according to the invention according to the actual needs, while remaining within the scope of the invention, given the teachings of the present disclosure. For example with respect to the provision of a slurry inlet or overflow, in one embodiment the thickening apparatus further comprises a movable baffle arranged on at least one of the slurry inlet and the overflow. For example, the flapper opens (or lifts) to expose the mud inlet or overflow and closes (or drops) to close the mud inlet or overflow. In another embodiment, the concentration device according to the present invention may further comprise a partition, as described below in connection with fig. 1 b.

Fig. 1b is a schematic view showing a movable thickener arranged with a partition according to the present invention. In contrast to the mobile thickener shown in fig. 1a, the thickening apparatus 100 of the mobile thickener shown in fig. 1b may further comprise a partition 120, the partition 120 being vertically arranged within the tank 110 such that a U-shaped flow channel is formed between the slurry inlet 111 and the overflow port 112. The movable chassis 200 of the movable thickener shown in fig. 1b, the tank 110 of the thickening apparatus 100, the cone 130, the underflow pipe 140 and the underflow discharge valve 150, etc. are the same or similar to those described in the foregoing, and will not be described again here. The separator 120 will be described below.

The partition 120 is vertically disposed in the case 110, and the partition 120 may be connected to the case 110 or not, if the connection is integrally formed or detachably connected. The material of the spacer 120 may be a metal or non-metal material such as iron, copper, aluminum, rubber, plastic, glass, etc., and may be selected according to the properties of the slurry to be processed. The baffle 120 may be disposed in the tank 110 between the slurry inlet 111 and the overflow 112, and one or more pieces may be disposed to form at least one U-shaped flow channel in one tank 110. The shape of the spacer 120 is not limited to the planar straight plate shown in fig. 1 b. For example, in one embodiment, the partition 120 may be a T-shaped partition, which may be comprised of a top plate and a riser vertically disposed within the case 110. The top plate of the T-shaped partition forms a shield at the top of the slurry inlet 111 and the overflow port 112, and thus can play a certain role in guiding and preventing splashing when the fluid flows in or is discharged. In one embodiment, the T-shaped partition plate can be connected with other components through the top plate, so that the T-shaped partition plate or the concentrating device can be fixed and the like. In another embodiment, the baffle 120 may be a corrugated baffle to further increase the contact area with the slurry. In yet another embodiment, the baffle 120 may be a dashed-line baffle. Compared with the inclined plate arrangement of the inclined plate thickener, the vertically arranged partition plate 120 has the advantages of simple structure, small volume and the like, and can be moved.

The partition 120 according to the present invention is described above in connection with fig. 1b as an example, and can be adjusted by those skilled in the art as needed, for example, the number of partitions can be more or less as needed. The structure of the baffle can be adjusted as required. In addition, the number of the concentration devices 100 according to the present invention may not be limited to one shown in fig. 1a and 1b, and may be arranged in a plurality, and the arrangement of the plurality of concentration devices 100 may include a plurality, and a step arrangement of the plurality of concentration devices 100 will be described below with reference to fig. 2.

According to an embodiment of the invention, the mobile thickener may comprise a plurality of thickening apparatuses and a mobile chassis, the plurality of thickening apparatuses constituting a plurality of thickening apparatus sets, the plurality of thickening apparatus sets being arranged on the mobile chassis, and the slurry inlets of the thickening apparatuses in the next thickening apparatus set in adjacent two stages being connected with the overflow ports of the thickening apparatuses in the previous thickening apparatus set, wherein at least one of the thickening apparatuses may be included in each of the thickening apparatus sets. As will be exemplified below in connection with fig. 2. To facilitate viewing the arrangement of the multi-stage concentrator group, fig. 2 is a top view showing the multi-stage concentrator group. As shown in fig. 2, the mobile thickener may include a multi-stage thickener set and a mobile chassis (not shown), wherein the multi-stage thickener set may include a primary thickener set L1 (shown in dotted line block), a secondary thickener set L2 (shown in dotted line block), a tertiary thickener set L3 (shown in dotted line block), and the like; wherein each stage of concentration plant group may comprise one or more concentration plants according to the present invention, for example, the illustrated first stage concentration plant group L1 comprises concentration plants 100-11 and concentration plants 100-12, etc., the second stage concentration plant group L2 comprises concentration plants 100-21 and concentration plants 100-22, etc., and the third stage concentration plant group L3 comprises concentration plants 100-31 and concentration plants 100-32, etc.

The structures of the concentration devices 100-11, 100-12, 100-21, 100-22, 100-31, 100-32, etc. are the same as or similar to the structure of the concentration device shown in fig. 1b, and thus the description thereof is omitted. However, in order to facilitate the observation of the corresponding parts of the concentrating device in the top view shown in fig. 2, the following description will be given by way of example only with respect to the concentrating devices 100-11 and 100-12. The thickening apparatus 100-11 may include a tank 110-11 having a slurry inlet 111-11 on one side of the tank 110-11 and an overflow 112-11 on the other side of the tank 110-11, a baffle 120-11, a cone 130-11, an underflow pipe (not shown), and an underflow discharge valve (not shown). The box 110-11 may be a hollow cylinder and the cone 130-11 may be a cone. The thickening apparatus 100-12 may include a tank 110-12 having a slurry inlet 111-12 on one side of the tank 110-12 and an overflow 112-12 on the other side of the tank 110-12, a baffle 120-12, a cone 130-12, an underflow pipe (not shown), and an underflow discharge valve (not shown). The housing 110-12 may be a hollow cylinder and the cone 130-12 may be a cone. The other concentrating devices 100-21, 100-22, 100-31, 100-32, etc. shown in fig. 2 are the same as or similar to the concentrating devices 100-11 and 100-12, and thus, are not described in detail herein.

As shown in fig. 2, the slurry inlets 111-21, 111-22 of the thickeners 100-21, 100-22 in the next-stage thickener set (e.g., the second-stage thickener set L2) in the adjacent two stages (e.g., the first-stage thickener set L1 and the second-stage thickener set L2) are connected to the overflow ports 112-11, 112-12 of the thickeners 100-11, 100-12 in the previous-stage thickener set (e.g., the first-stage thickener set L1) in the adjacent two stages (e.g., the first-stage thickener set L1 and the second-stage thickener set L2). Furthermore, the second-stage concentrator group L2 and the third-stage concentrator group L3 are also adjacent two stages, and therefore the slurry inlets 111-31, 111-32 of the concentrators 100-31, 100-32 of the third-stage concentrator group L3 (i.e., the next-stage concentrator group) in the second-stage concentrator group L2 and the third-stage concentrator group L3 are connected to the overflow ports 112-21, 112-22 of the concentrators 100-21, 100-22 of the second-stage concentrator group L2 (i.e., the previous-stage concentrator group). The overflow ports 112-31, 112-32 of the concentration devices 100-31, 100-32 of the third-stage concentration device group L3 can be connected with the slurry inlet of the concentration device of the next-stage concentration device group; if it has no next-stage concentrator group, the overflow ports 112-31, 112-32 can be used as the total overflow port of the whole thickener for the outflow of the final overflow liquid. Similarly, the slurry inlets 111-11, 111-12 of the thickeners 100-11, 100-12 of the primary set of thickeners L1 may be connected to the overflow of the thickener of the primary set of thickeners above it; if it does not have a previous concentrator group, the slurry inlets 111-11, 111-12 can be used as a total slurry inlet for the entire thickener for the input of the slurry to be treated. According to the arrangement, the slurry to be treated can flow in from the slurry inlet of the first-stage concentration device group L1, passes through the multiple thickening of the multi-stage concentration device group, the concentrated slurry is discharged from the underflow pipe of each stage concentration device group, and the obtained upper overflow liquid finally flows out from the overflow port of the third-stage concentration device group L3.

From the above description, it should be understood that the next and previous concentrator banks in adjacent two concentrator banks described herein are opposed and may be arranged according to the direction of flow of the fluid (e.g., slurry), e.g., the next concentrator bank is downstream in the flow of the fluid relative to the previous concentrator bank; and the upper stage concentrator group is located upstream of the fluid flow with respect to the lower stage concentrator group. However, this is not a limitation of the present invention, and those skilled in the art can set the setting according to the actual working condition, and can flexibly adjust the change of the fluid flowing direction.

While the arrangement of the multi-stage concentrator group according to the present invention has been described above with reference to fig. 2, it will be understood by those skilled in the art that the multi-stage concentrator group shown in fig. 2 is exemplary and not limiting, and the number, structure, arrangement, etc. of the concentrators can be adjusted as desired. For example, the number of the concentration devices in each stage of the concentration device group is not limited to two shown in fig. 2, and more or less concentration devices may be provided according to the needs, and the number of the concentration devices in each stage of the concentration device group may be equal or different. And the number of stages of the multistage concentration device group is not limited to three stages shown in fig. 2, and more or less may be arranged as needed. The shape of the concentration device is also not limited to that shown in fig. 2, and may be provided in a square shape or the like. The structure and shape of each concentrator in the multi-stage concentrator group can be the same or different. The connection mode between the concentrating devices in the adjacent two-stage concentrating device group is not limited to that shown in fig. 2, and can be adjusted according to the structures of the slurry inlet and the overflow port. Various arrangements of the multi-stage concentration device group according to the present invention will be described below exemplarily with reference to fig. 3 to 8.

As shown in FIG. 3, in one embodiment, the baffles 120-1, 120-2, 120-3 of the concentrator 100-1, 100-2, 100-3 may each be configured as T-shaped baffles, and the top plates of the three T-shaped baffles may be connected to direct and splash-proof the entire flow of fluid (slurry).

While an arrangement including only one thickener per stage of the thickener set has been described above in connection with fig. 3, it will be understood by those skilled in the art that the configuration of the mobile thickener shown in fig. 3 is exemplary and not limiting, e.g., the number of stages of the multi-stage thickener set may not be limited to three stages, and more or less may be provided as desired. The structure of the plurality of concentration devices in the multistage concentration device group is not limited to the structure shown in fig. 3, and for example, the partition may be provided in other shapes. Further, the plurality of concentration devices of the multi-stage concentration device group may have the same or different structures. Further, the connection manner between the adjacent concentration devices may not be limited to the fitting manner shown in fig. 3, for example, in one embodiment, the box bodies of two adjacent concentration devices may share one surface, so that a plurality of concentration device groups may be connected in an integrated manner. The adjacent concentration devices are connected in a mode of being attached to or sharing the box surface, so that the space can be saved, the layout of the whole thickener is more compact, and the size of the thickener is favorably reduced. In addition, the arrangement of the multi-stage concentration device groups connected in sequence is not limited to the arrangement in sequence at the same height as shown in fig. 3, for example, in one embodiment, the multi-stage concentration device groups are arranged in a high-low step type connection manner, which will be described below with reference to fig. 4.

According to another embodiment of the invention, the overflow of the thickener may be lower than the slurry inlet, and the plurality of thickener sets may be connected in a high-low-level ladder. The mobile thickener as shown in fig. 4 may include a multi-stage thickener bank (a primary thickener bank L1, a secondary thickener bank L2, a tertiary thickener bank L3) and a mobile chassis 200. Wherein the primary concentrator group L1 (shown by a dotted line) includes a concentrator 100-1, the secondary concentrator group L2 (shown by a dotted line) includes a concentrator 100-2, and the tertiary concentrator group L3 (shown by a dotted line) includes a concentrator 100-3. The primary concentrator group L1 is adjacent to the secondary concentrator group L2, and the secondary concentrator group L2 is adjacent to the tertiary concentrator group L3. The first-stage concentration device group L1, the second-stage concentration device group L2 and the third-stage concentration device group L3 are connected in a high-low step mode. Whereby the concentration apparatus 100-1, the concentration apparatus 100-2 and the concentration apparatus 100-3 are connected in a high-low cascade.

According to such a configuration, the process of thickening the slurry to be treated by the thickener is the same as or similar to the path described above with reference to fig. 3, and will not be described herein again, except that the fluid (slurry) flow path in the thickener is a plurality of continuous high-low step-type U-shaped flow paths, which has the advantages of facilitating the outflow of overflow liquid and preventing the reverse flow of slurry (such as overflow from the slurry inlet).

While the multi-stage concentrator group is illustrated in a high-low cascade connection arrangement in conjunction with fig. 4, it will be understood by those skilled in the art that the above description in conjunction with fig. 4 is exemplary and not limiting, for example, the number of stages of the multi-stage concentrator group is not limited to the three stages shown in fig. 4, and more or less may be provided as desired; the number of the concentration devices in each stage of the concentration device group is not limited to one shown in the figure, and may be more, for example, two, three or more, as needed. The plurality of concentration devices in each stage of concentration device group can be connected or not connected in sequence, for example, in one embodiment, the plurality of concentration devices in each stage of concentration device group can be connected in a manner of being attached to each other two by two, so that the space is saved, and the size of the thickener is further reduced. The configuration of the concentrating device is not limited to that shown in fig. 4, for example, in one embodiment, the partition is a T-shaped partition, the top plates of the T-shaped partitions of a plurality of concentrating devices are connected, and the risers of the T-shaped partitions of different concentrating devices can be set to different lengths.

While the above description has been made with reference to fig. 3 and 4 for the case where one concentration device is included in each concentration device group, it should be understood by those skilled in the art that the number of concentration devices in each concentration device group may not be limited to one, and may be more, as needed, for example, according to another embodiment of the present invention, a plurality of concentration devices may be included in each concentration device group, and the number of concentration devices in two adjacent concentration device groups may be the same, and may be connected in a one-to-one correspondence manner. The situation described in this embodiment will be described in detail below with reference to fig. 5.

Fig. 5 is a schematic top view illustrating one arrangement of a multi-stage concentrator group in accordance with an embodiment of the present invention. The multistage concentration device group shown in fig. 5 may include a primary concentration device group L1 (shown by a dotted line box), a secondary concentration device group L2 (shown by a dotted line box), a tertiary concentration device group L3 (shown by a dotted line box), a quaternary concentration device group L4 (shown by a dotted line box), and the like; wherein each stage of concentration plant group may comprise a plurality of concentration plants according to the present invention, for example, the illustrated first stage concentration plant group L1 may comprise concentration plants 100-11, concentration plants 100-12, concentration plants 100-13, etc., the second stage concentration plant group L2 may comprise concentration plants 100-21, concentration plants 100-22, concentration plants 100-23, etc., the third stage concentration plant group L3 may comprise concentration plants 100-31, concentration plants 100-32, concentration plants 100-33, etc., and the fourth stage concentration plant group L4 may comprise concentration plants 100-41, concentration plants 100-42, concentration plants 100-43, etc. As shown in the figure, the box bodies of the concentration devices 100-11, 100-12, 100-13, 100-21, 100-22, 100-23, 100-31, 100-32, 100-33, 100-41, 100-42 and 100-43 can be arranged into hollow cuboids or cubes, and the cone hoppers can be arranged into square cone hoppers to be matched with the bottom surface shapes of the box bodies connected with the cone hoppers. The structures of the concentration devices 100-11, 100-12, 100-13, 100-21, 100-22, 100-23, 100-31, 100-32, 100-33, 100-41, 100-42, 100-43, etc. are the same as or similar to the structures of the concentration devices described in the foregoing, for example, the arrangement of the components including the partition, the underflow pipe, etc., and thus, the description thereof is omitted.

As shown in fig. 5, the primary L1 and secondary L2 concentrator groups are adjacent and the number of concentrators in the primary L1 and secondary L2 concentrator groups may be equal, e.g., each comprising three concentrators; the secondary L2 and tertiary L3 concentrating units are adjacent to each other, and the number of concentrating units in the secondary L2 and tertiary L3 concentrating units may be equal, for example, each comprising three concentrating units; the third concentrator group L3 is in turn adjacent to the fourth concentrator group L4, and the number of concentrators in the third concentrator group L3 and the fourth concentrator group L4 may be equal, for example, each comprising three concentrators.

Further, the primary concentrating device group L1 and the concentrating devices in the secondary concentrating device group L2 may be connected in a one-to-one correspondence. The one-to-one connection is, for example, a connection of one concentrator of the primary concentrator group L1 to one concentrator of the secondary concentrator group L2, a connection of another concentrator of the primary concentrator group L1 to another concentrator of the secondary concentrator group L2, and so on. For example, the concentrators 100-11 of the primary concentrator group L1 may be connected to the concentrators 100-21 of the secondary concentrator group L2, the concentrators 100-12 may be connected to the concentrators 100-22, and the concentrators 100-13 may be connected to the concentrators 100-23. Similarly, the second-stage concentration unit group L2 and the concentration units in the third-stage concentration unit group L3 may be connected in a one-to-one correspondence. For example, the illustrated concentrators 100-21 may be coupled to the concentrators 100-31, the concentrators 100-22 may be coupled to the concentrators 100-32, and the concentrators 100-23 may be coupled to the concentrators 100-33. Similarly, the three-stage concentration device group L3 and the concentration devices in the four-stage concentration device group L4 may be connected in a one-to-one correspondence. For example, the illustrated concentrators 100-31 may be coupled to concentrators 100-41, concentrators 100-32 may be coupled to concentrators 100-42, and concentrators 100-33 may be coupled to concentrators 100-43.

Furthermore, the connection modes among the concentration device 100-11, the concentration device 100-21, the concentration device 100-31 and the concentration device 100-41 can be that an overflow port 112-11 of the concentration device 100-11 is connected with a slurry inlet 111-21 of the concentration device 100-21, an overflow port 112-21 of the concentration device 100-21 is connected with a slurry inlet 111-31 of the concentration device 100-31, and an overflow port 112-31 of the concentration device 100-31 is connected with a slurry inlet 111-41 of the concentration device 100-41. In one embodiment, the overflow port 112-11 is in fluid communication with the slurry inlet 111-21, the overflow port 112-21 is in fluid communication with the slurry inlet 111-31, and the overflow port 112-31 is in fluid communication with the slurry inlet 111-41. Similarly, the connection mode between the concentration units 100-12, 100-22, 100-32, 100-42 and the connection mode between the concentration units 100-13, 100-23, 100-33, 100-43 may be the same as or similar to the connection mode between the concentration units 100-11, 100-21, 100-31, 100-41, and will not be described herein again.

Further, according to an embodiment of the present invention, a plurality of the concentration devices in the concentration device group of each stage may be connected in sequence. For example, as shown in fig. 5, the concentration devices 100-11, 100-12, 100-13 in the primary concentration device group L1 may be connected, and in one embodiment, the concentration device 100-11 and the concentration device 100-12 are connected in a fitting manner, and the concentration device 100-12 and the concentration device 100-13 are connected in a fitting manner. Similarly, the arrangement of the concentration devices in the second stage concentration device group L2, the third stage concentration device group L3 and the fourth stage concentration device group L4 may be the same as or similar to that in the first stage concentration device group L1, and thus, the description thereof is omitted. With this arrangement, the slurry inlets 111-11 of the thickening apparatuses 100-11, 111-12 of the thickening apparatuses 100-12, and 111-13 of the thickening apparatuses 100-13 can together be the total slurry inlet of the thickener; the overflow ports 112-41 of the concentration devices 100-41, the overflow ports 112-42 of the concentration devices 100-42 and the overflow ports 112-43 of the concentration devices 100-43 can be used together as the total overflow port of the thickener. In practical use, the slurry to be treated can enter the thickener from the slurry inlets 111-11, 111-12 and 111-13 at the same time, and the overflow liquid can flow out from the overflow ports 112-41, 112-42 and 112-43 at the same time. Thus, the treatment capacity of the slurry can be improved, and continuous production can be realized. According to the configuration, the tight connection of the multi-stage concentration device groups can be realized, a compact structure is formed, the space is saved, and the volume of the thickener is favorably reduced and the number of the concentration devices is further increased.

The embodiment of the arrangement of the multi-stage concentration device group according to the present invention is described above with reference to fig. 5, and the arrangement of the multi-stage concentration device group according to the present invention can finally obtain clarified overflow liquid, which is beneficial to further recovery and treatment of the overflow liquid and is of great significance. It should be understood by those skilled in the art that the arrangement of the multi-stage concentrator groups shown in fig. 5 is exemplary and not limiting, for example, the number of stages of the concentrator groups may not be limited to four stages, and more or less may be provided as desired; the number of the concentration devices in each stage of the concentration device group can be not limited to three, and more or less concentration devices can be arranged according to the requirement; the arrangement may be the same as or similar to that of the thickening apparatus shown in fig. 5 and will not be described in detail here. Fig. 5 shows an arrangement of a plurality of concentration devices in adjacent two-stage concentration device groups, and a case where the number of concentration devices in adjacent two-stage concentration device groups is not equal will be described below with reference to fig. 6.

Fig. 6 is a schematic top view of an embodiment showing the unequal number of concentrators in adjacent two-stage concentrator groups according to the present invention. Since the movable chassis of the mobile thickener is the same or similar to that described in the foregoing, it is not described here in detail and thus not shown in fig. 6. The following will describe the multi-stage concentration apparatus set shown in fig. 6. According to one embodiment of the invention, the number of concentration devices in the next concentration device group in two adjacent stages is smaller than the number of concentration devices in the previous concentration device group, and each of the concentration devices in the next concentration device group may be connected to at least one of the concentration devices in the previous concentration device group. In another embodiment, the number of the concentration devices in the next stage concentration device group is one less than the number of the concentration devices in the previous stage concentration device group.

The multi-stage concentration apparatus group as shown in fig. 6 may include a one-stage concentration apparatus group L1 (shown by a dotted line box), a two-stage concentration apparatus group L2 (shown by a dotted line box), and a three-stage concentration apparatus group L3 (shown by a dotted line box). The primary concentrating apparatus group L1 may be adjacent to the secondary concentrating apparatus group L2, and the number of concentrating apparatuses in the secondary concentrating apparatus group L2 (the next concentrating apparatus group) is less than that in the primary concentrating apparatus group L1 (the previous concentrating apparatus group), for example, the secondary concentrating apparatus group L2 may include two concentrating apparatuses 100-21, 100-22, and the primary concentrating apparatus group L1 may include three concentrating apparatuses 100-11, 100-12, 100-13. Similarly, the second concentrator group L2 may be adjacent to the third concentrator group L3, and the number of concentrators in the third concentrator group L3 (the next concentrator group) may be less than the number of concentrators in the second concentrator group L2 (the previous concentrator group), for example, one concentrator 100-31 may be included in the third concentrator group L3, and two concentrators 100-21, 100-22 may be included in the second concentrator group L2.

Further, each of the concentration devices in the next-stage concentration device group in the adjacent two-stage concentration device groups may be connected to at least one concentration device in the previous-stage concentration device group. This is illustrated below in connection with fig. 6. As shown in fig. 6, the primary thickener group L1 is adjacent to the secondary thickener group L2, and the thickeners 100 to 21 in the next one of the primary thickener groups (i.e., the secondary thickener group L2) may be connected to the thickeners 100 to 11 in the previous one of the primary thickener groups (i.e., the primary thickener group L1), while the other thickeners 100 to 22 in the secondary thickener group L2 may be connected to the thickeners 100 to 12, 100 to 13 in the primary thickener group L1. Similarly, the secondary concentrator group L2 is in turn adjacent to the tertiary concentrator group L3, wherein the concentrators 100-31 of the next concentrator group (i.e., the tertiary concentrator group L3) may be connected to the concentrators 100-21, 100-22 of the previous concentrator group (i.e., the secondary concentrator group L2).

The above description of the case where the number of the concentration devices in the two adjacent concentration device groups is different is described in conjunction with fig. 6, it can be understood that, during the thickening process of the slurry passing through the multi-stage concentration device group, the amount of the concentrated slurry collected in the concentration device groups of the later stages is gradually reduced, the overflow liquid of the upper layer is gradually clarified, and the multi-stage concentration device group is arranged in a manner similar to the trapezoidal arrangement (such as shown in fig. 6), so that the total number of the concentration devices is reduced, the volume of the thickener is reduced, the treatment capacity of the slurry can be ensured, and the volume and the weight of the thickener can be further reduced, which is beneficial to movement.

It should be understood by those skilled in the art that the arrangement shown in fig. 6, which is similar to a trapezoid, is exemplary and not limiting, and that those skilled in the art, given the teachings of this disclosure, may adjust the arrangement according to actual needs. For example, the number of stages of the multistage concentration apparatus group may not be limited to three stages in the drawing, and more or less may be provided as necessary. The number of the concentration devices in each stage of the concentration device group is not limited to one, two or three in the figure, and can be more according to the needs. The number of the concentration devices of the adjacent two-stage concentration device groups may not be limited to one difference, and may be set more than one difference, for example, two, three or more, as required. One concentration device in the next concentration device group in the adjacent two-stage concentration device groups is not limited to be connected with one or two concentration devices in the previous concentration device group, but can be connected more as required. For example, in one embodiment, the concentrator devices 100-21 shown in the figures may be increased in size to connect with 100-11, 100-12, 100-13 of the primary concentrator group L1. It will be appreciated that the sizes of the concentrators in the multi-stage concentrator group may be different, and that another embodiment of arranging concentrators of different sizes in the multi-stage concentrator group will be described with reference to fig. 7.

According to another embodiment of the invention the volume of the concentration devices of a partial group of the plurality of groups of concentration devices is smaller than the volume of the concentration devices of another partial group of groups of concentration devices. In one embodiment, the partial stage of the concentrator group is located at a lower level of the other partial stage of the concentrator group. FIG. 7 is a schematic diagram showing an embodiment of a different volumetric concentrator arrangement from a top view. Since the movable chassis of the mobile thickener is the same or similar to that described in the foregoing, it is not described here in detail and thus is not shown in fig. 7. As shown in fig. 7, the multi-stage concentration apparatus group may include a primary concentration apparatus group L1 (shown by a dotted line box), a secondary concentration apparatus group L2 (shown by a dotted line box), and a tertiary concentration apparatus group L3 (shown by a dotted line box). The first-stage concentration device group L1 may include concentration devices 100-11 and 100-12, the second-stage concentration device group L2 may include concentration devices 100-21 and 100-22, and the third-stage concentration device group L3 may include concentration devices 100-31 and 100-32. And the volumes of the concentration units 100-31, 100-32 in the tertiary concentration unit group L3 may be smaller than the volumes of the concentration units in the primary and secondary concentration unit groups L1, L2. The third-stage concentration unit L3 is located at the lower stage of the first-stage concentration unit L1 and the second-stage concentration unit L2.

From the above description, it should be understood that the lower stages described herein are relative and may be arranged according to the direction of flow of the fluid (e.g., mud), e.g., the lower stages are downstream of the fluid flow relative to the upper stages. Taking the example shown in fig. 7, the third concentrating device group L3 is located at the lower stage of the first concentrating device group L1 and the second concentrating device group L2, that is, the slurry can flow through the first concentrating device group L1 and the second concentrating device group L2 in sequence and then flow into the third concentrating device group L3. In practical applications, during the process of thickening the slurry by the multi-stage thickening device sets, the amount of the concentrated slurry collected in the later-stage thickening device sets is generally gradually reduced, and the overflow liquid on the upper layer is gradually clarified, so in one embodiment, a thickening device with a smaller volume (for example, similar to the exemplary arrangement of the multi-stage thickening device set shown in fig. 7) can be arranged in the later-stage thickening device sets, and the volume, the weight and the movement of the thickener can be further reduced while the requirement on the treatment capacity can be met.

While one embodiment of arranging different volumes of concentrators in a multi-stage concentrator group is described above in connection with fig. 7, it should be understood by those skilled in the art that the multi-stage concentrator group shown in fig. 7 is illustrative and not limiting, for example, the number of stages of the multi-stage concentrator group may not be limited to three stages as shown, and more or less may be provided as desired. The number of the concentration devices in each stage of the concentration device group is not limited to two as can be shown in fig. 7, and more or less may be provided as necessary. In one embodiment, the number of concentrators in adjacent two-stage concentrator sets may be different. The concentrator group provided with the smaller-volume concentrator is not limited to the three-stage concentrator group shown in fig. 7, and may be adjusted as needed, for example, in one embodiment, the volumes of the concentrators in the five-stage concentrator group and the six-stage concentrator group are smaller than those in the other-stage concentrator group.

Further, in another embodiment, the volume of the concentration device in the next-stage concentration device group in the adjacent two stages may be smaller than the volume of the concentration device in the previous-stage concentration device group. Namely, the concentrating devices among all the stages in the multi-stage concentrating device group are arranged in a way that the volumes of the concentrating devices are reduced in sequence. Such an arrangement may further reduce the volume and weight of the thickener, thereby facilitating flexible movement. And the volumes of the plurality of the concentrating devices in each stage of the concentrating device group can be set to be equal or unequal according to requirements.

While the number, volume, etc. of the multiple concentrators in the multi-stage concentrator group are described above with reference to fig. 3-7, embodiments of the concentrator including a turbidity sensor and a overflow collection tube according to the present invention will be described with reference to fig. 8.

According to yet another embodiment of the present invention, the mobile thickener may further comprise at least one turbidity sensor and at least one overflow liquid collection pipe, wherein the turbidity sensor is arranged on the concentration devices in the partial-stage concentration device group in the multi-stage concentration device group to monitor the turbidity of the overflow liquid in the concentration devices; the overflow liquid collecting pipe is connected to the overflow port of the concentration device provided with the turbidity sensor, and an automatic control device is arranged on the overflow liquid collecting pipe and connected with the turbidity sensor so as to control the opening and closing of the overflow liquid collecting pipe according to the turbidity of the overflow liquid.

As shown in fig. 8, the mobile thickener may include a multi-stage thickener set and a mobile chassis 200. Wherein the multi-stage concentration device group may include a primary concentration device group L1 (shown by a dotted line box), a secondary concentration device group L2 (shown by a dotted line box), and a tertiary concentration device group L3 (shown by a dotted line box). The primary concentrating device group L1 may include at least one concentrating device 100-1, the secondary concentrating device group L2 may include at least one concentrating device 100-2, the tertiary concentrating device group L3 may include at least one concentrating device 100-3, and the concentrating device 100-1, the concentrating device 100-2, and the concentrating device 100-3 may be connected in sequence, wherein an overflow port of the concentrating device 100-1 may be connected to a slurry inlet of the concentrating device 100-2, and an overflow port of the concentrating device 100-2 may be connected to a slurry inlet of the concentrating device 100-3.

In this embodiment, a turbidity sensor may be disposed on the concentration devices in the two-stage concentration device group L2 to monitor the turbidity of the overflow liquid in the concentration devices in the two-stage concentration device group. Such as the thickening apparatus 100-2 shown in fig. 8, has at least one turbidity sensor 170-2 disposed thereon. Further, a collection tube for overflow liquid may be disposed (including directly or indirectly connected) on the overflow port of the concentration device in which the turbidity sensor is disposed. For example, at least one overflow collection tube 180-2 is connected to the overflow port of the concentration device 100-2 shown in FIG. 8. an automatic control device 190-2 can be disposed on the at least one overflow collection tube 180-2. the automatic control device 190-2 can be connected to the turbidity sensor 170-2 by wire or wirelessly. The automatic control device 190-2 of the concentration device 100-2 can automatically control the opening and closing of the overflow liquid collection pipe 180-2 according to the turbidity of the overflow liquid fed back by the turbidity sensor 170-2 so as to control the outflow path of the overflow liquid in the concentration device 100-2. For example, in one embodiment, when the turbidity sensor 170-2 detects that the overflow liquid has a low turbidity and reaches a limit value at which it can be collected, the automatic control device 190-2 can automatically open the overflow liquid collection pipe 180-2 to allow the overflow liquid in the concentration device 100-2 to be directly drained from the overflow liquid collection pipe 180-2 for further subsequent processes without entering the concentration device 100-3 for further concentration. Therefore, the device can reduce equipment loss, shorten thickening time, save labor cost and realize automatic control.

Further, the overflow port of the thickener 100-2, the overflow liquid collecting pipe 180-2, and the slurry inlet of the thickener 100-3 may be connected by, for example, providing a three-way pipe, so that two outflow paths of the overflow liquid of the thickener 100-2 can be realized. In another embodiment, the portable thickener may further comprise a movable baffle disposed on the overflow port of the concentration device (i.e., the concentration device in which the turbidity sensor is disposed) in the partial-stage concentration device group, and the overflow liquid collection pipe is connected to the movable baffle. For example, a movable baffle plate can be arranged on the overflow port of the concentration device 100-2 shown in fig. 8, the overflow liquid collecting pipe 180-2 is connected to the movable baffle plate, when the movable baffle plate closes the overflow port, the overflow liquid can flow out from the overflow liquid collecting pipe 180-2, when the movable baffle plate leaves the overflow port, the overflow liquid can flow into the slurry inlet of the concentration device 100-3 through the overflow port, and the automatic control device 190-2 can control the opening and closing of the overflow liquid collecting pipe 180-2 by controlling the movement of the movable baffle plate, so that two outflow paths of the overflow liquid of the concentration device 100-2 are realized.
