Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically a multi-stage filtration device for improving the filtration efficiency of organic phase chemicals. Background Technology

[0002] In the field of electronic chemicals, the filtration of organic phase chemicals is a critical step in the production process. However, some domestically produced organic phase electronic chemicals currently face numerous filtration challenges. The quality of their raw materials varies greatly, often containing numerous impurities, and the products have high viscosity, resulting in poor liquid flowability. Simultaneously, some solid additives are difficult to fully dissolve, further increasing the complexity of filtration.

[0003] Traditional single-stage cartridge filters exhibit significant limitations when processing organic-phase electronic chemicals. Due to the limited filtration area, a large number of chemicals must pass through a single cartridge sequentially, significantly extending filtration time and severely impacting production efficiency. Furthermore, as filtration continues, the cartridge quickly reaches its filtration limit, at which point the particle count in the product becomes difficult to control within the ideal range, and the filtration effect drops sharply, failing to meet the stringent purity requirements of high-precision electronic chemical production. This situation restricts the quality improvement of domestically produced organic-phase electronic chemicals and, to some extent, hinders the rapid development of related industries.

[0004] Therefore, this utility model provides a multi-stage filtration device to improve the filtration efficiency of organic phase chemicals. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-stage filtration device that improves the filtration efficiency of organic phase chemicals, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage filtration device for improving the filtration efficiency of organic phase chemicals, comprising a filter housing, a base frame, and two side doors. The filter housing contains two sets of parallel filter tanks. An inner support seat is installed on the inner wall of the bottom of the filter housing. Both sets of filter tanks are mounted on the top of the inner support seat. Each set contains three filter tanks, and each of the six filter tanks contains a filter element. The six filter tanks are installed upside down. An inlet pipe and a drain pipe are provided between the two sets of filter tanks. The inlet pipe and the drain pipe are connected through the internal space of the two sets of filter tanks. Two inlet valves and two drain valves are installed on the inlet pipe and the drain pipe, respectively. An inlet pressure gauge and a drain pressure gauge are installed at one end of the inlet pipe and the drain pipe, respectively.

[0007] Preferably, two side mounting plates are installed inside the filter housing, and two first water inlet hoses are installed between the two side mounting plates. Both first water inlet hoses are connected to the top of the corresponding filter tank.

[0008] Preferably, two second water inlet hoses are installed between the two side mounting plates, and both second water inlet hoses are connected to the bottom of the corresponding filter tank. Two reversing valves are installed between the first water inlet hose and the corresponding second water inlet hose, and the four reversing valves are respectively installed on one side of the corresponding side mounting plate.

[0009] Preferably, two L-shaped support plates are installed on the inner wall of the bottom end of the filter housing, and two pipe valves are installed on the top of each of the two L-shaped support plates. A drain pipe is provided on the outer side of the two L-shaped support plates, and the drain pipe is connected to the internal space of the two second water inlet hoses.

[0010] Compared with the prior art, the present invention has the following advantages: 1. This utility model achieves multi-stage filtration with two branches through two sets of filter tanks. Organic phase chemical liquids can be divided into two paths and enter the two sets of filter tanks for simultaneous filtration, which increases the throughput and shortens the time required for electronic chemicals to reach the filtration limit, thereby improving the filtration efficiency of chemicals. Furthermore, when filtering organic electronic chemicals with high viscosity, the working pressure of a single filter element is reduced by adjusting the opening flow of the corresponding inlet and outlet valves, avoiding the phenomenon of particulate matter being washed off the filter element due to excessive pressure, thus improving the filtration effect and extending the service life of the filter element.

[0011] 2. This utility model uses an inverted filter element inside the filter tank to make the liquid flow from bottom to top, which is opposite to the sedimentation direction of impurities. This helps to prevent filtered impurities from being mixed back into the filtrate, further improving the filtration effect and ensuring the quality of the effluent. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2 A multi-stage filtration device for improving the filtration efficiency of organic phase chemicals includes a filter housing 1, a base frame 11 and two side doors 12. The filter housing 1 is provided with two sets of parallel filter tanks 2. An inner support seat 13 is installed on the inner wall of the bottom end of the filter housing 1, and both sets of filter tanks 2 are installed on the top of the inner support seat 13.

[0016] The two sets of filter tanks 2 each contain three filter elements, and each of the six filter tanks 2 is installed with a filter element. The six filter tanks 2 are installed upside down. An inlet pipe 21 and a drain pipe 22 are provided between the two sets of filter tanks 2. The inlet pipe 21 and the drain pipe 22 are connected through the internal space of the two sets of filter tanks 2.

[0017] It should be noted that the filter tank 2 described in this embodiment is located between the liquid inlet pipe 21 and the liquid outlet pipe 22.

[0018] Two inlet valves 211 and two outlet valves 221 are installed on the inlet pipe 21 and the outlet pipe 22, respectively. An inlet pressure gauge 212 and an outlet pressure gauge 222 are installed at one end of the inlet pipe 21 and the outlet pipe 22, respectively.

[0019] It should be noted that the inlet valve 211 and the outlet valve 221 described in this embodiment are both installed on the top of the inner support 13, and the two sets of filter tanks 2 are located between the two inlet valves 211 and the two outlet valves 221.

[0020] Specifically, the base frame 11 supports the bottom of the filter housing 1. The base frame 11 is opened or closed via two side doors 12, which are made of transparent material, allowing staff to easily observe the internal operation of the equipment. Liquid flows from bottom to top within the filter tank 2, filtering impurities inside the filter element. The equipment delivers organic phase chemical liquid to the two sets of filter tanks 2 via the inlet pipe 21. The organic phase chemical liquid can be divided into two streams and enter the two sets of filter tanks 2 for simultaneous filtration, increasing throughput and shortening the time required for electronic chemicals to reach their filtration limit, thereby improving the filtration efficiency of the chemicals. Alternatively, by adjusting one inlet valve 211 and one outlet valve 221, one branch can be closed, allowing the filter element of that single branch to be used for pre-filtration of the chemical liquid raw material. This allows the chemical liquid raw material to undergo preliminary filtration through the filter element of that branch, removing larger particulate impurities. The pre-filtered liquid can then be discharged through the outlet pipe 22. The system can be further processed as needed, reducing the hassle of replacing filter elements and cleaning pipelines. Furthermore, when filtering highly viscous organic electronic chemicals, adjusting the opening flow rate of the corresponding inlet valve 211 and outlet valve 221 reduces the working pressure of a single filter element, preventing particulate matter from being washed off the filter element due to excessive pressure. This improves filtration efficiency and extends the filter element's lifespan. During filtration, continuously monitor the readings of the inlet pressure gauge 212 and outlet pressure gauge 222. Under normal circumstances, the pressure should gradually increase, but the rate of increase should remain stable. If the pressure rises sharply, it may indicate filter element blockage, requiring timely action, such as reducing the flow rate, inspecting the filter element, or stopping filtration for cleaning and replacement. Simultaneously, during filtration, the inverted filter element causes the liquid to flow from bottom to top, opposite to the sedimentation direction of impurities. This helps prevent filtered impurities from re-mixing into the filtrate, further improving filtration efficiency and ensuring the quality of the effluent.

[0021] In one embodiment of this utility model, such as Figures 1-2 As shown, two side mounting plates 3 are installed inside the filter housing 1, and two first water inlet hoses 31 are installed between the two side mounting plates 3. Both first water inlet hoses 31 are connected to the top of the corresponding filter tank 2.

[0022] It should be noted that the first water inlet hose 31 described in this embodiment delivers cleaning water to the inside of the filter tank 2.

[0023] Specifically, the two first water inlet hoses 31 inject water into the filter tank 2 through the connection of the cleaning water source, so that the water source can backwash the filter element from above, thereby making it easier to clean the impurities filtered in the filter element and improving the service life of the filter element.

[0024] In one embodiment of this utility model, such as Figures 1-2As shown, two second water inlet hoses 32 are installed between the two side mounting plates 3. Both second water inlet hoses 32 are connected to the bottom of the corresponding filter tank 2. Two reversing valves 33 are installed between the first water inlet hose 31 and the corresponding second water inlet hose 32. The four reversing valves 33 are respectively installed on one side of the corresponding side mounting plate 3.

[0025] It should be noted that the second inlet hose 32 described in this embodiment guides the waste liquid and waste gas intercepted inside the corresponding filter tank 2 to be discharged, and the reversing valve 33 is connected to the external water source.

[0026] Specifically, the water source for rinsing the filter tank 2 and filter element through the first inlet hose 31 is discharged through the second inlet hose 32. The second inlet hose 32 guides the wastewater out. The water source is controlled to be supplied to the first inlet hose 31 or the second inlet hose 32 through the reversing valve 33, so that the water source can be used to rinse the filter element and the wastewater discharge path, making it more flexible to use.

[0027] In one embodiment of this utility model, such as Figures 1-2 As shown, two L-shaped support plates 4 are installed on the inner wall of the bottom end of the filter housing 1. Two pipe valves 41 are installed on the top of each of the two L-shaped support plates 4. Drain pipes 42 are provided on the outer side of the two L-shaped support plates 4. The drain pipes 42 are connected to the internal space of the two second water inlet hoses 32.

[0028] It should be noted that the pipe valve 41 described in this embodiment blocks the passage between the second water inlet hose 32 and the filter tank 2.

[0029] Specifically, the two second inlet hoses 32 transport wastewater to the drain pipe 42, and the wastewater and exhaust gas are discharged through the drain pipe 42. By closing the pipe valve 41, the water source between the reversing valve 33 and the second inlet hoses 32 cannot flow back to the position below the filter tank 2, so that the water source for rinsing the drain pipe 42 can be directly discharged.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working Principle: This device is mainly used for filtering organic phase chemicals. The filter housing 1 contains two sets of parallel filter tanks 2, each set containing three tanks. Inverted filter elements are installed within each tank 2. Liquid enters and exits from the bottom up within the filter tank 2. Organic phase chemical liquids can enter both sets of filter tanks 2 simultaneously, increasing throughput and shortening the time to reach the filtration limit. By adjusting the inlet valve 211 and outlet valve 221, one branch can be closed, allowing the filter element of that single branch to be used for pre-filtration of the chemical liquid raw material, removing larger particulate impurities. The pre-filtered liquid can be discharged through the outlet pipe 22 for collection or further processing. When filtering highly viscous organic electronic chemicals, adjusting the opening flow of the corresponding inlet valve 211 and outlet valve 221 can reduce the working pressure of a single filter element, preventing particulate matter from being washed away from the filter element due to excessive pressure, improving filtration efficiency, and extending filter element life. During filtration, the readings of the inlet pressure gauge 212 and outlet pressure gauge 222 are observed to determine if the filter element is clogged. Two side mounting plates 3 are installed inside the filter housing 1. The first inlet hose 31 between them can be connected to a cleaning water source to backwash the filter element in the filter tank 2, remove impurities, and improve the filter element's lifespan. The second inlet hose 32 guides the waste liquid and exhaust gas intercepted inside the filter tank 2 to be discharged. The valves 41 at the top of the two L-shaped support plates 4 on the bottom inner wall of the filter housing 1 can block the passage between the second inlet hose 32 and the filter tank 2. The drain pipe 42 discharges the wastewater and exhaust gas.
