[0035] See also Figure 1 and Figure 2 An embodiment of the present application provides a multi-channel liquid distribution device, including a valve body assembly 1 and a drive assembly 2. The valve body assembly 1 is used to connect a liquid inlet pipe and a liquid outlet pipe, so that the liquid in the liquid inlet pipe can be input into the liquid outlet pipe through the valve body assembly 1, so that the liquid outlet pipe outputs the liquid to a designated area. The drive assembly 2 is used to control the use state of the valve body assembly 1 to ensure the coordination effect between the valve body assembly 1 and the liquid inlet pipe and the liquid outlet pipe.
[0036] In a specific configuration, the valve body assembly 1 includes a first valve body 11, a second valve body 12, and a plurality of valve cores 13. A first channel group is provided on the first valve body 11, and the first channel group includes a plurality of first channels 111, and the plurality of first channels 111 are evenly and spacedly distributed on the first valve body 11 around the axis of the first valve body 11. Each first channel 111 can be connected to a liquid outlet pipe, so that the valve body assembly 1 can supply liquid to the plurality of liquid outlet pipes through the first valve body 11.
[0037] The second valve body 12 is coaxially arranged on the first valve body 11, and a second channel group is arranged on the second valve body 12. The second channel group includes a plurality of second channels 121, and the plurality of second channels 121 are evenly and spacedly distributed on the second valve body 12 around the axis of the second valve body 12, and the spacing between the second channel 121 and the axis of the second valve body 12 is consistent with the spacing between the first channel 111 and the axis of the first valve body 11, so that the second channel 121 can be coaxial with the first channel 111. Each second channel 121 can be connected to a liquid inlet pipe, so that the valve body assembly 1 can input liquid in a plurality of liquid inlet pipes into the first valve body 11 through the second valve body 12, so as to supply liquid to a plurality of liquid outlet pipes through a plurality of first channels 111 of the first valve body 11.
[0038] Each second channel 121 is provided with a valve core 13 capable of blocking the first channel 111, so as to ensure the sealing effect of the first valve body 11 and the second valve body 12 when conveying liquid, and prevent the conveyed liquid from flowing out through the gap between the second channel 121 and the first channel 111. The valve core 13 is provided with a third channel connecting the second channel 121 and the first channel 111, so that the liquid in the second channel 121 can flow into the first channel 111 through the third channel.
[0039] The driving assembly 2 includes a first driver and a second driver. The first driver is connected to the first valve body 11 in a transmission manner and can drive the first valve body 11 to rotate relative to the second valve body 12 around its own axis to replace the first channel 111 corresponding to the position of the second channel 121, so that the second channel 121 can be connected to another liquid outlet channel through another first channel 111. The second driver is connected to the second valve body 12 in a transmission manner and can drive the second valve body 12 to move relative to the first valve body 11 along its own axis to adjust the distance between the valve core 13 and the first channel 111, so that the valve core 13 enters or leaves the first channel 111, so that the valve core 13 does not affect the rotation between the first valve body 11 and the second valve body 12, and can ensure the coordination effect between the first channel 111 and the second channel 121 after the position change.
[0040] Specifically, the first driver is a motor, and the second driver is a hydraulic press. A first rotating shaft is provided in the first valve body 11, a first gear is provided on the first rotating shaft, and the first valve body 11 is connected to the first rotating shaft through the first gear. The motor is connected to the first rotating shaft and can drive the first rotating shaft and the first valve body 11 to rotate. A second rotating shaft is provided in the second valve body 12, and the second rotating shaft is connected to the first rotating shaft through a coupling, so that when the motor drives the first valve body 11 to rotate through the first rotating shaft, the second valve body 12 will not rotate accordingly, and when the hydraulic press drives the second valve body 12 to move relative to the first valve body 11 along its own axis, the first valve body 11 will not move accordingly.
[0041] When the multi-channel liquid dispensing device of the present application is used, different liquids can be outputted in sequence through the corresponding first channel 111 and the second channel 121. When the direction of the liquid needs to be changed, the second valve body 12 can be driven to move by the second driver, so that the valve core 13 in the second channel 121 leaves the first valve body 11, and the first valve body 11 can be driven to rotate by the first driver, so that the second channel 121 can be aligned with another first channel 111, so as to change the output direction of the liquid without changing the type of the incoming liquid. That is, the multi-channel liquid dispensing device of the present application combines the first valve body 11 with the second valve body 12 and the plurality of valve cores 13, so that compared with the current structure of setting multiple automatic control valves, the present application does not need to send a signal to each valve separately when switching the direction of the liquid, and the operation of the system control is simple, the cost and failure rate are low, and the operation is more stable. In addition, the present application can make the lengths of the multiple liquid inlet pipes connected to the second valve body 12 consistent, and the lengths of the multiple liquid outlet pipes connected to the first valve body 11 consistent, so that the liquid entering the adsorption column is not affected by the length of the pipe, and the distribution after entering the adsorption column is more uniform.
[0042] See also Figure 1-Figure 3In one embodiment, an annular groove 112 is provided on the side of the first valve body 11 facing the second valve body 12, and the plurality of first channels 111 are all connected to the annular groove 112. An annular protrusion 122 is provided on the side of the second valve body 12 facing the first valve body 11, and the plurality of second channels 121 all penetrate the annular protrusion 122, and the annular protrusion 122 is located in the annular groove 112. The annular protrusion 122 is positioned by the annular groove 112, so that the stability between the first valve body 11 and the second valve body 12 is effectively enhanced.
[0043] Specifically, the annular groove 112 is coaxially arranged with the first valve body 11, and an annular valve seat 113 is arranged in the annular groove 112. The annular valve seat 113 has a first sealing surface facing the annular protrusion 122. The annular protrusion 122 is coaxially arranged with the second valve body 12, and the annular protrusion 122 can abut against the first sealing surface when the valve core 13 blocks the first channel 111, so as to ensure the sealing effect of the first valve body 11 and the second valve body 12 when conveying liquid, so that the liquid in the second channel 121 can flow into the first channel 111 only through the valve core 13.
[0044] In one of the embodiments, a closing valve seat 114 is provided in the first channel 111. The closing valve seat 114 has a second sealing surface facing the valve core 13. The second sealing surface can abut against the valve core 13 when the valve core 13 blocks the first channel 111, so as to ensure the sealing effect of the first valve body 11 and the valve core 13 when transporting liquid, so that the liquid in the second channel 121 only flows into the first channel 111 through the valve core 13.
[0045] In one embodiment, at least two sealing rings 14 are provided between the first valve body 11 and the second valve body 12, and the valve core 13 is located in the area enclosed by two adjacent sealing rings 14 to further ensure the sealing effect of the first valve body 11 and the second valve body 12 when transporting liquid.
[0046] See also Figure 1 and Figure 3 In one embodiment, an elastic component 3 is further provided in the second channel 121, the elastic component 3 is connected to the valve core 13, and the elastic direction of the elastic component 3 is consistent with the axial direction of the second channel 121. The elastic force given to the valve core 13 by the elastic component 3 can make the valve core 13 better block the first channel 111. It can be understood that when the second driver drives the second valve body 12 to move, so that the valve core 13 in the second channel 121 leaves the first valve body 11, the elastic component 3 returns to its normal length; when the second driver drives the second valve body 12 to move, so that the valve core 13 in the second channel 121 enters the first valve body 11, the valve core 13 contacts the first valve body 11 and blocks the first channel 111, and the elastic component 3 is compressed.
[0047] In one embodiment, the elastic component 3 includes an elastic member 31, a piston member 32 and a connecting member 33. The elastic member 31 is arranged in the second channel 121. The piston member 32 is arranged on the elastic member 31 and abuts against the inner circumferential surface of the second channel 121. The connecting member 33 connects the piston member 32 and the valve core 13, and the stability between the elastic member 31 and the valve core 13 is improved by the piston member 32.
[0048] Specifically, a bracket is provided in the second channel 121, one end of the elastic member 31 in the elastic direction is connected to the bracket, and the other end of the elastic member 31 in the elastic direction is connected to the piston member 32. The piston member 32 is provided with a through hole for liquid to pass through, and the valve core 13 is located on the side of the piston member 32 away from the elastic member 31, and is connected to the piston member 32 through the connecting member 33. When the second driver drives the second valve body 12 to move, so that the valve core 13 in the second channel 121 leaves the first valve body 11, the valve body can move downward under the action of its own gravity, thereby driving the piston member 32 to move, so that the elastic member 3 returns to its normal length; when the second driver drives the second valve body 12 to move, so that the valve core 13 in the second channel 121 enters the first valve body 11, the valve core 13 contacts the first valve body 11 and gives the piston member 32 a force toward the elastic member 31, so that the piston member 32 moves and the elastic member 31 is compressed.
[0049] See also Figure 1 and Figure 2 In one embodiment, there are multiple first channel groups, which are coaxially arranged on the first valve body 11, and the first channels 111 in two adjacent first channel groups are arranged at intervals along the radial direction of the first valve body 11; there are multiple second channel groups, which are coaxially arranged on the second valve body 12, and the second channels 121 in two adjacent second channel groups are arranged at intervals along the radial direction of the second valve body 12. By providing multiple first channel groups and multiple second channel groups, the number of first channels 111 and second channels 121 can be effectively increased, so that the multi-channel liquid distribution device of the present application can be used in conjunction with more liquid inlet pipes and liquid outlet pipes.
[0050] Specifically, along the radial direction of the first valve body 11, the spacing between each two adjacent first channel groups is equal, so that the multiple first channel groups are arranged more evenly on the first valve body 11. Along the radial direction of the second valve body 12, the spacing between each two adjacent second channel groups is equal, so that the multiple second channel groups are arranged more evenly on the second valve body 12.
[0051] According to another aspect of the present application, a continuous ion exchange device is provided, comprising a multi-channel liquid preparation device as described in any one of the above embodiments.
[0052] The continuous ion exchange equipment of the present application can utilize a multi-channel liquid distribution device to allow different liquids to be output in sequence through the corresponding first channel 111 and the second channel 121. When the liquid direction needs to be changed, the second driver can drive the second valve body 12 to move, so that the valve core 13 in the second channel 121 leaves the first valve body 11, and the first driver drives the first valve body 11 to rotate, so that the second channel 121 can be aligned with another first channel 111, so as to change the output direction of the liquid without changing the type of incoming liquid. Compared with the method of setting multiple automatic control valves, the present application is simple to operate, has a low failure rate, and is more stable in operation. It can also ensure that the feed liquid entering the adsorption column is not affected by the length of the pipeline, and is more evenly distributed after entering the adsorption column.
[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
