Description

Technical Field

[0001] This application relates to the technical field of metabolite treatment devices, and in particular to a metabolite treatment device for surface water / seawater based on cyclic extraction. Background Technology

[0002] The core purpose of extracting surface water / seawater is to "concentrate and enrich" and "purify" it so that we can detect extremely low concentrations of crucial chemical substances.

[0003] Even after initial filtration, new particulate matter may be introduced during extraction due to reagents, containers, or operational procedures. These particles can clog the chromatographic column, leading to increased back pressure, poor peak shape, and even damage to the expensive column. Using a syringe filter for secondary filtration reduces impurities in the liquid.

[0004] Because the internal filter membrane is fixed together by welding, cleaning it becomes extremely difficult. In actual use, both sides of the filter membrane absorb impurities, and this fixed connection method makes it difficult to thoroughly clean both sides. As usage time increases, more and more impurities accumulate on the filter membrane, directly affecting its filtration efficiency, which needs improvement. Utility Model Content

[0005] The purpose of this application is to provide a device for treating metabolites in surface water / seawater based on cyclic extraction, in order to facilitate the cleaning of impurities attached to the filter membrane.

[0006] The present application provides a surface water / seawater metabolite treatment device based on cyclic extraction, which adopts the following technical solution: it includes a first shell and a second shell detachably connected to the first shell. The first shell is provided with an inlet channel, and the second shell is provided with an outlet channel and a mounting cavity communicating with the outlet channel. A first filter membrane is detachably connected in the mounting cavity. A first mounting ring is connected to the outer peripheral surface of the first filter membrane. The first mounting ring is connected to a fixing member, and the first mounting ring is fixed in the mounting cavity by the fixing member.

[0007] By adopting the above technical solution, the first housing and the second housing are detachably connected, allowing the first housing to be separated from the second housing. The first filter membrane and the first mounting ring can be removed from the mounting cavity, enabling thorough cleaning of both sides of the first filter membrane, thereby reducing impurities adhering to the first filter membrane and improving its filtration efficiency. After the impurities on the first filter membrane are cleaned, the first filter membrane and the first mounting ring are reinstalled in the mounting cavity. The first filter membrane is fixed in the mounting cavity by the first mounting ring and fasteners, ensuring a stable installation and guaranteeing the filtration effect.

[0008] Optionally, the second housing is provided with a first mounting groove communicating with the mounting cavity, the first mounting groove being used to mate with the first mounting ring.

[0009] By adopting the above technical solution, the first mounting ring is installed in the first mounting groove, the outer surface of the first mounting ring is in contact with the inner wall of the first mounting groove, and the inner wall of the first mounting groove plays a positioning role for the installation of the first mounting ring, so that the first mounting ring is accurately installed in the corresponding position.

[0010] Optionally, the first mounting ring is provided with a stop portion, and the second housing is provided with a stop groove communicating with the first mounting groove, the stop groove being used to cooperate with the stop portion.

[0011] By adopting the above technical solution, when the first mounting ring is installed in the mounting cavity, the stop part is engaged with the stop groove, and the stop part fits against the inner wall of the stop groove. The cooperation between the stop part and the stop groove restricts the rotation of the first mounting ring around its own axis, thereby improving the stability of the first mounting ring installed in the mounting cavity.

[0012] Optionally, the fastener includes a fixing rod disposed on the first mounting ring, wherein when the first housing is mounted on the second housing, the first housing abuts against the fixing rod.

[0013] By adopting the above technical solution, when the first housing abuts against the fixing rod, the first mounting ring is clamped by the inner wall of the first mounting groove and the fixing rod, restricting the movement of the first mounting ring within the first mounting groove, thereby improving the stability of the first filter membrane installed in the first mounting groove. When the first housing separates from the second housing, the fixing rod can serve as a handle, providing a lifting end for workers to remove the first mounting ring from the first mounting groove.

[0014] Optionally, a second filter membrane is detachably connected inside the mounting cavity. The second filter membrane is connected to a second mounting ring. The second filter membrane is located between the first filter membrane and the outlet channel. The pore size of the second filter membrane is smaller than that of the first filter membrane. The second housing is provided with a second mounting groove communicating with the mounting cavity. The second mounting groove is used to cooperate with the second mounting ring.

[0015] By adopting the above technical solution, surface water / seawater enters the device through the inlet channel, undergoes preliminary filtration through the first filter membrane, and then undergoes secondary filtration through the second filter membrane with a smaller pore size located between the first filter membrane and the outlet channel. This can further reduce impurities in the liquid and improve the purification effect. In addition, the second filter membrane is detachably connected by the second mounting ring and the second mounting groove, which is convenient for cleaning and replacement and ensures the filtration effect.

[0016] Optionally, the second mounting ring is connected to a limiting rod, which is used to abut against the first mounting ring.

[0017] By adopting the above technical solution, when the second mounting ring is installed in the second mounting groove, the first mounting ring is pressed against the limiting rod, and the second mounting ring is clamped by the limiting rod and the inner wall of the second mounting groove, thereby improving the stability of the second mounting ring installed in the second mounting groove.

[0018] Optionally, the first mounting ring is provided with a limiting groove, which is used to cooperate with the limiting rod.

[0019] By adopting the above technical solution, when the second mounting ring is installed in the second mounting groove, the limiting rod is engaged in the limiting groove, and the outer surface of the limiting rod is in contact with the inner wall of the limiting groove. The cooperation between the limiting rod and the limiting groove restricts the rotation of the second mounting ring around its own axis, thereby improving the stability of the second mounting ring installed in the second mounting groove.

[0020] Optionally, the second housing is provided with a threaded portion, and the first housing is provided with a threaded groove, the threaded groove being used for threaded connection with the threaded portion.

[0021] By adopting the above technical solution, the threaded portion of the second housing is threadedly connected to the threaded groove of the first housing, achieving a detachable connection between the first and second housings. This facilitates the cleaning and replacement of the first filter membrane inside the mounting cavity. The threaded engagement between the threaded portion and the threaded groove improves the disassembly efficiency of the first and second housings.

[0022] Optionally, the second housing is provided with a protruding ring, the first housing is provided with a groove, the groove is used to cooperate with the protruding ring, the protruding ring is provided with an elastic locking block, and the first housing is provided with a locking groove communicating with the groove, the locking groove is used to engage with the elastic locking block.

[0023] By adopting the above technical solution, when the second housing is installed on the first housing, the elastic block abuts against the first housing. The elastic block is compressed and undergoes elastic deformation and maintains the tendency to elastically reset until the elastic block corresponds to the slot. The elastic block elastically resets, and the cooperation between the elastic block and the slot can ensure the stability of the connection.

[0024] Optionally, a sealing ring is connected between the first housing and the second housing. The sealing ring is used to seal the gap between the first housing and the second housing. Both the first housing and the second housing are provided with annular grooves, which are used to cooperate with the sealing ring.

[0025] By adopting the above technical solution, the sealing ring seals the gap between the first housing and the second housing, preventing liquid leakage and ensuring the normal operation of the device. The sealing ring fits snugly against the inner wall of the annular groove, and the inner wall of the annular groove restricts the movement of the sealing ring, improving the stability of the sealing ring installed between the first housing and the second housing. Furthermore, the fit between the inner wall of the annular groove and the sealing ring increases the liquid movement path, improving the sealing effect.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The first housing and the second housing are detachably connected, allowing the first housing to be separated from the second housing. The first filter membrane and the first mounting ring can be removed from the mounting cavity, enabling thorough cleaning of both sides of the first filter membrane, thereby reducing impurities adhering to the first filter membrane and improving its filtration efficiency.

[0027] 2. When the first housing is pressed against the fixing rod, the first mounting ring is clamped by the inner wall of the first mounting groove and the fixing rod, restricting the movement of the first mounting ring within the first mounting groove, thereby improving the stability of the first filter membrane installed in the first mounting groove. After the first housing is separated from the second housing, the fixing rod serves as a handle, providing a lifting end for the operator to remove the first mounting ring from the first mounting groove.
