Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of matrix treatment devices, and in particular to a matrix washing salt device for bioassay experiments. Background Technology
[0002] In the research and development of fertilizers, synergists, pesticides, and soil in agriculture, biotesting offers significant advantages over field trials. Biotesting can be conducted in laboratories, greenhouses, or confined spaces, greatly reducing experimental costs and resource consumption while improving controllability and repeatability. Therefore, biotesting is widely used in research such as efficacy verification, concentration screening, and dosage optimization. Especially in new technology exploration and experiments requiring high precision, pot experiments have become the preferred method.
[0003] However, the soil or substrate used in pot experiments has a significant impact on the effectiveness of the test substances. If the substrate salinity is too high, it may lead to poor crop growth or biased experimental results, thus affecting the accuracy and reliability of subsequent fertilizer development. Currently commonly used substrates, such as coconut coir, peat moss, river sand, and pond mud, generally suffer from excessively high salinity.
[0004] To solve this problem, traditional methods usually involve rinsing the substrate by soaking it in nearby water sources. However, the salinity of the substrate may not decrease due to the high salinity of the water source itself. Alternatively, the substrate may be rinsed continuously, which results in a large amount of wastewater. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a matrix washing salt device for bioassay experiments, which can reliably ensure the reduction of matrix salinity and reduce wastewater volume.

[0010] A water collection chamber is connected to the bottom of the substrate chamber. The filter holes and the water collection chamber of the water collection chamber are connected sequentially along the water flow direction. The water collection chamber is connected to a reverse osmosis membrane.
[0011] A circulating water tank is connected to a water collection tank. The circulating water tank has a circulating water cavity. The water collection cavity, the reverse osmosis membrane, and the circulating water cavity are connected sequentially along the water flow direction.
[0012] A circulating water pipe is connected to a water pump, and both ends of the circulating water pipe are respectively connected to the circulating water chamber and the substrate chamber.
[0013] Furthermore, the filtration device divides the matrix chamber into an upper chamber and a lower chamber, and the upper chamber, the filter hole, the lower chamber, the leakage through hole, the water collection chamber and the circulating water chamber are connected in sequence; the two ends of the circulating water pipe are respectively connected to the circulating water chamber and the upper chamber of the matrix chamber.
[0014] Furthermore, the matrix washing salt device for bioassay experiments also includes a negative pressure suction device, which is located in the upper cavity and is used to drive the water at the top of the upper cavity to the bottom of the upper cavity.
[0015] Furthermore, the matrix washing salt device for bioassay experiments also includes a return water chamber, which is installed in the upper cavity. The return water chamber has a return water cavity and is provided with multiple water passages connecting the return water cavity and the upper cavity. The two ends of the circulating water pipe are respectively connected to the circulating water cavity and the return water cavity.
[0016] Furthermore, the return water cavity has an annular structure and extends circumferentially around the upper cavity.
[0017] The outer wall of the return water chamber is disposed opposite to the cavity wall of the upper cavity, and all the water passages are located on the side of the return water chamber away from the cavity wall of the upper cavity.

[0022] Furthermore, the bottom of the matrix chamber has a funnel structure, the lower cavity has a cone structure, and the horizontal cross-sectional area of the lower cavity gradually decreases from top to bottom.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0024] By installing a filter screen inside the substrate chamber of the substrate tank, the substrate is trapped, preventing it from entering the water collection chamber of the water collection tank through the leakage holes. The water collection chamber is used to hold wastewater. To reduce the consumption of clean water, a reverse osmosis membrane is used to trap salt, allowing clean water to pass through the reverse osmosis membrane and enter the circulating water chamber of the circulating water tank. A water pump then continuously pumps the clean water into the substrate chamber to repeatedly clean the substrate, thereby reducing wastewater production and saving clean water consumption. In this way, the substrate can also be cleaned to below the target salinity. Furthermore, the filtration device traps the substrate first, preventing it from clogging the reverse osmosis membrane and maintaining its continuous operation. Attached Figure Description

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] See Figures 1-3 The matrix washing salt device for bioassay experiments in this embodiment includes: a matrix chamber 1, a filter device 2, a water collection chamber 3, a circulating water chamber 5, and a circulating water pipe 6.
[0033] The substrate chamber 1 has a substrate cavity 11 for containing the substrate; a drainage hole 12 is provided at the bottom of the substrate chamber 1. Commonly used substrates, such as coconut coir, peat, river sand, and pond mud, generally have excessively high salinity. Therefore, the substrate to be cleaned can be contained in the substrate chamber 1, while the drainage hole 12 allows the water (i.e., solvent) after cleaning to flow out of the substrate cavity 11.
[0034] A filter device 2 is installed inside the matrix cavity 11. The filter device 2 has filter holes 21 and divides the matrix cavity 11 into an upper cavity 111 and a lower cavity 112. The upper cavity 111, filter holes 21, lower cavity 112, and leakage through hole 12 are connected in sequence. The filter device 2 can be a conventional filter screen or mesh, etc. The filter device 2 is used to trap the matrix to prevent the matrix from entering the leakage through hole 12. The filter holes 21 are used to allow the water after washing to flow to the leakage through hole 12, but do not allow the matrix to flow into the leakage through hole 12.
[0035] The water collection chamber 3 is connected to the bottom of the substrate chamber 1. The water collection cavity 31 of the water collection chamber 3 is connected to the leakage through hole 12. The bottom of the water collection chamber 3 is connected to the reverse osmosis membrane 4. The water after washing the substrate has a high salinity and enters the water collection cavity 31 through the leakage through hole 12 under its own gravity.
[0036] The circulating water tank 5 is connected to the water collection tank 3. The circulating water tank 5 has a circulating water cavity 51. The water collection tank 3, the reverse osmosis membrane 4 and the circulating water cavity 51 are connected in sequence along the direction of solvent flow.
[0037] The circulating water pipe 6 is connected to the water pump 7, and the two ends of the circulating water pipe 6 are respectively connected to the circulating water chamber 51 and the upper chamber 111.
[0038] During operation, the substrate to be cleaned is first loaded into the upper chamber 111 of the substrate chamber 11 and retained by the filter device 2. Then, the clean water pump 7 of the circulating water tank 5 is sent to the upper chamber 111 of the substrate chamber 1 by the water pump 7. Under the action of gravity, the clean water carrying salts passes sequentially through the filter hole 21, lower chamber 112, leakage through hole 12 and water collection chamber 31 of the filter device 2. Under the interception of the reverse osmosis membrane 4, only the clean water passes through the reverse osmosis membrane 4 to enter the circulating water chamber 51, thereby retaining the salts in the water collection chamber 31. In this way, the circulating water chamber 51 can continuously provide low-salt clean water to the substrate chamber 11 of the substrate chamber 1 to continuously clean the substrate until the substrate meets the test conditions.
[0039] Obviously, by installing a filter screen in the matrix chamber 11 of the matrix chamber 1, the matrix is intercepted by the filter screen, preventing the matrix from entering the water collection chamber 31 of the water collection chamber 3 along the leakage through-hole 12. The water collection chamber 31 is used to contain wastewater. To reduce the consumption of clean water, the reverse osmosis membrane 4 intercepts salt, allowing clean water to pass through the reverse osmosis membrane 4 and enter the circulating water chamber 51 of the circulating water chamber 5. Then, the water pump 7 continuously pumps the clean water into the matrix chamber 11 to repeatedly clean the matrix, thereby reducing the wastewater production and saving clean water consumption. In this way, the matrix can also be cleaned to below the target salinity. In addition, the filter device 2 intercepts the matrix first, thereby preventing the matrix from clogging the reverse osmosis membrane 4 and maintaining the continuous operation of the reverse osmosis membrane 4.
[0040] It should be noted that, as an alternative arrangement, the upper cavity 111 and lower cavity 112 of the matrix cavity 11 can be distributed not only vertically but also horizontally, i.e., divided into a left cavity and a right cavity. However, compared to the distribution of left and right cavities, the upper cavity 111 is located above the lower cavity 112, which has the advantage of utilizing the gravity of water flow and enhances the cleaning effect on the matrix. In addition, the matrix cavity 11 does not necessarily need to be divided into an upper cavity 111 and a lower cavity 112 by the filter device 2; the filter device 2 can simply be installed at the bottom of the matrix cavity 11.
[0041] In this embodiment, to prevent water from accumulating in the upper cavity 111, the substrate washing device for bioassay experiments also includes a negative pressure suction device 8. The negative pressure suction device 8 is located inside the upper cavity 111 and is used to drive the water from the top of the upper cavity 111 to the bottom of the upper cavity 111, thereby improving the cleaning efficiency of the substrate. The negative pressure suction device 8 can be a negative pressure suction pump or similar structure.
[0042] In this embodiment, the matrix washing device for bioassay experiments also includes a return water chamber 9, which is installed in the upper cavity 111. The return water chamber 9 has a return water cavity 91 and multiple water passages 92 connecting the return water cavity 91 and the upper cavity 111. The two ends of the circulating water pipe 6 are respectively connected to the circulating water cavity 51 and the return water cavity 91. With this configuration, since the matrix cannot enter the return water cavity 91, clean water can be temporarily stored in the return water cavity 91, and then wait for the clean water to enter the upper cavity 111 through the water passages 92. In this way, the circulating water pipe 6 can draw a certain amount of clean water into the return water cavity 91, thereby serving as a reserve water source for the upper cavity 111.
[0043] In this embodiment, in order to ensure that the water in the return water cavity 91 enters the upper cavity 111 evenly and improves the uniform cleaning effect on the substrate, the return water cavity 91 has a ring structure and extends circumferentially around the upper cavity 111.
[0044] In this embodiment, the outer wall 93 of the return water chamber 9 is disposed opposite to the cavity wall 1111 of the upper cavity 111, and all the water passages 92 are located on the side of the return water chamber 9 away from the cavity wall 1111 of the upper cavity 111. This arrangement, where the return water chamber 9 is closely surrounded by the cavity wall 1111 and the water passages 92 face the middle of the upper cavity 111, ensures a consistent water flow direction, thereby improving the cleaning effect.
[0045] In this embodiment, in order to make the substrate more uniformly cleaned, multiple water passage holes 92 are distributed at intervals along the extension direction of the return water cavity 91, and multiple water passage holes 92 are distributed at intervals along the direction of gravity.
[0046] In this embodiment, in order to collect water quality data, the water collection tank 3 has a first detection port 32 connected to the water collection cavity 31. The first detection port 32 is used for the insertion of the first buoyancy salinity meter 101. When the first buoyancy salinity meter 101 reaches the target value, the control system connected to the first buoyancy salinity meter 101 can control the alarm device to sound an alarm, thereby reminding the staff to open the first drain pipe connected to the water collection cavity 31 to discharge the wastewater.
[0047] In this embodiment, the circulating water tank 5 has a second detection port 52 that connects to the circulating water cavity 51. The second detection port 52 is used for connecting a second buoyancy salinity meter. When the second buoyancy salinity meter reaches the target value, the control system connected to the second buoyancy salinity meter 102 can control the alarm device to sound an alarm, thereby reminding the staff to open the second drain pipe connected to the circulating water tank 5 to drain the wastewater. Also, a clean water source can be provided to the circulating water tank 5 by connecting the inlet water pipe to the circulating water cavity 51.
[0048] In this embodiment, to prevent the reverse osmosis membrane 4 from becoming clogged, a secondary filtration element 10 is provided at the connection between the lower cavity 112 and the leakage through-hole 12. By filtering the matrix through the secondary filtration element, the reverse osmosis membrane 4 can be prevented from being clogged or damaged by the missed matrix.
[0049] In this embodiment, to reduce the area of the secondary filter element, the bottom of the substrate chamber 1 has a funnel structure, the lower cavity 112 has a conical structure, and the horizontal cross-sectional area of the lower cavity 112 gradually decreases from top to bottom. This design eliminates the need for a large-sized secondary filter element, thus saving costs.
[0050] Additionally, it should be noted that, in order to facilitate the maintenance of the water collection tank 3, the reverse osmosis membrane 4, and the circulating water tank 5, the water collection tank 3 and the circulating water tank 5 are connected in a detachable manner, and the reverse osmosis membrane 4 is stacked on the top support frame of the circulating water tank 5.
