Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, specifically to a parallel automatic filtration system for titanium rod filters. Background Technology

[0002] When removing impurities from liquid products, activated carbon is typically added and stirred to adsorb the impurities. The liquid is then separated from the activated carbon using a titanium rod filter. Titanium rod filter elements are porous filtration structures made of sintered titanium powder, offering advantages such as high precision, high temperature resistance, corrosion resistance, and high mechanical strength. They are widely used in chemical, pharmaceutical, and food industries, providing excellent filtration for activated carbon and allowing for disassembly, washing, and reuse. During filtration, as more activated carbon is filtered out, the filter element may become clogged, resulting in reduced flow and increased pressure at the filter head. For solid-liquid separation processes with high activated carbon content, traditional manual control methods make it difficult to visually observe the internal condition of the titanium rod filter. If the selected titanium rod filter has insufficient capacity, it can easily become filled with activated carbon, clogging the pipeline and causing production line shutdowns. If the filtered liquid is a hazardous chemical, repeated on-site disassembly of pipelines and titanium rod filters leads to a high frequency of exposure to hazardous materials, increasing the risk of fire and poisoning.

[0003] On the other hand, after filtration is completed, the activated carbon in the titanium rod filter needs to be removed and disposed of. During the removal process, static electricity is easily generated. If the activated carbon adsorbs organic liquid materials, there is also a risk of static electricity sparking and causing a fire during the removal process. Utility Model Content

[0004] The purpose of this invention is to provide a parallel automatic filtration system for titanium rod filters, so as to at least partially solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parallel automatic filtration system for titanium rod filters, comprising a titanium rod filter group, a recovery storage tank group, a feed main pipe, and a discharge main pipe. The titanium rod filter group includes multiple titanium rod filters connected in parallel; the recovery storage tank group includes multiple recovery storage tanks connected in parallel; the feed main pipe is connected to the feed end of each of the titanium rod filters through multiple feed branch pipes, each feed branch pipe being equipped with an automatic control valve; the discharge main pipe has its front end connected to the discharge end of each of the titanium rod filters through multiple discharge branch pipes, and its rear end connected to each of the recovery storage tanks through multiple liquid inlet branch pipes, each discharge branch pipe and liquid inlet branch pipe being equipped with an automatic control valve; it also includes a first pressure transmitter connected to the feed main pipe and located at the front end of the feed branch pipes; and a second pressure transmitter connected to each discharge branch pipe.

[0006] In a preferred embodiment, a flow switch for flow monitoring is also connected to the main discharge pipe, and the flow switch is located in the pipe section between the discharge branch pipe and the liquid inlet branch pipe.

[0007] In a preferred embodiment, a self-regulating damping valve is also connected to the discharge main pipe, and the damping valve is located before the flow switch.

[0008] In a preferred embodiment, the main feed pipe is further connected to a displacement liquid feed pipe and / or a tap water feed pipe located at the front end of the feed branch pipe, and the displacement liquid feed pipe and the tap water feed pipe are respectively equipped with automatic control valves.

[0009] In a preferred embodiment, the number of the recovery storage tanks is three, which are respectively configured to recover filtrate, replacement fluid and cleaning wastewater.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The automatic filtration system provided by this utility model sets up a titanium rod filter group and installs pressure transmitters on the feed main pipe and the filter discharge branch pipe. It can monitor the inlet and outlet pressure difference of each filter in real time and automatically switch other filters, realizing continuous automated operation of the filtration process. It solves the problem of pipeline blockage and production line shutdown caused by activated carbon filling the filter, and significantly improves safety, avoiding the need for manual disassembly and replacement of filters during the filtration process.

[0012] 2. By setting up a replacement liquid inlet pipe, a tap water inlet pipe, and a corresponding recovery storage tank, the system can automatically introduce replacement medium and water after filtration to replace and wash the activated carbon trapped in the titanium rod filter, rinse the filter, and recover the corresponding liquid. This not only reduces material loss but also greatly reduces the risk of static sparks generated by friction during the subsequent manual removal of waste activated carbon.

[0013] 3. By installing a self-regulating damping valve on the discharge main pipe, the system can actively adjust the resistance at the moment of filter switching, smooth pressure and flow fluctuations, protect downstream equipment from impact, and thus improve the stability of the entire system operation.

Therefore, they should not be construed as limitations on this utility model.

[0019] See Figure 1 This embodiment discloses a parallel automatic filtration system for titanium rod filters, including a titanium rod filter group and a recycling tank group. The titanium rod filter group includes multiple titanium rod filters 1 connected in parallel, and the recycling tank group includes multiple recycling tanks 2 connected in parallel.

[0020] The automatic filtration system also includes a feed manifold 3 and a discharge manifold 4. The feed manifold 3 is connected to the feed end of the titanium rod filter assembly, and the discharge manifold 4 is connected between the discharge end of the titanium rod filter assembly and the feed end of the recovery storage tank assembly.

[0021] Specifically, the main feed pipe 3 is connected to multiple parallel feed branch pipes 31 that communicate with the feed ends of each titanium rod filter 1. The number of feed branch pipes 31 is the same as the number of titanium rod filters 1. The material to be filtered enters each titanium rod filter 1 through the main feed pipe 3 and the feed branch pipes 31. Each feed branch pipe 31 is equipped with a self-control valve 5. The main feed pipe 3 is also connected to a first pressure transmitter 6, which is located at the front end of the feed branch pipes 31.

[0022] The front end of the main discharge pipe 4 is connected to multiple branch discharge pipes 41, which are connected to the discharge ends of each titanium rod filter 1. The number of branch discharge pipes 41 is the same as the number of titanium rod filters 1. The filtered liquid flows into the main discharge pipe 4 through the branch discharge pipes 41. Each branch discharge pipe 41 is equipped with an automatic control valve 5 and a second pressure transmitter 7. The rear end of the main discharge pipe 4 is connected to multiple inlet branch pipes 42, which are connected to each recovery storage tank 2. The number of inlet branch pipes 42 is the same as the number of recovery storage tanks 2, and each inlet branch pipe 42 is equipped with an automatic control valve 5. A flow switch 8 for flow monitoring is also connected to the main discharge pipe 4. The flow switch 8 is located between the titanium rod filter group and the recovery storage tank group, specifically in the pipe section between the branch discharge pipes 41 and the inlet branch pipes 42. The flow switch 8 adopts existing technology.

[0023] In this embodiment, the feed main pipe 3 is also connected to a displacement liquid feed pipe 9 and a tap water feed pipe 10. The displacement liquid feed pipe 9 and the tap water feed pipe 10 are arranged side by side and are both located at the front end of the feed branch pipe 31. Each of them is equipped with a self-control valve 5.

[0024] As is understood, in this embodiment, the automatic filtration system also includes a controller 11. All the self-controlled valves 5, pressure transmitters, and flow switches 8 in this embodiment are electrically connected to the controller 11 to achieve automatic control of the system. The control method of the controller 11 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. Therefore, the control method and circuit connection will not be explained in detail in this embodiment.

[0025] Furthermore, in this embodiment, a self-regulating damping valve 12 is also connected to the discharge main pipe 4. This damping valve 12 is located before the flow switch 8 and is linked to the controller 11 to control pressure fluctuations when switching titanium rod filters 1. In practical applications, when switching from a blocked or nearly blocked titanium rod filter 1 to a new titanium rod filter 1, the system pipeline resistance decreases suddenly, causing the fluid velocity to increase instantaneously and generating huge pressure shocks and flow peaks. This violent fluctuation can impact downstream equipment such as the flow switch 8 and the recovery storage tank 2, affecting their lifespan. In production processes requiring precise control, it may also affect product quality. This embodiment, by installing a self-regulating damping valve 12 on the discharge main pipe 4, increases the system resistance when switching titanium rod filters 1. The valve is then slowly opened after the new titanium rod filter 1 has stabilized, thereby effectively suppressing flow shocks caused by sudden changes in resistance, protecting downstream equipment, and improving the stability and safety of system operation.

[0026] For ease of understanding, the application principle of the automatic filtration system provided in this embodiment is introduced as follows. For example, the titanium rod filter group in the automatic filtration system includes three sets of titanium rod filters 1 connected in parallel, and the recovery storage tank group includes three sets of recovery storage tanks 2 connected in parallel.

[0027] 1. Filtering stage:

[0028] Liquid material containing activated carbon enters the system through the main feed pipe 3. The controller 11 controls the opening of the automatic control valves 5 corresponding to the first titanium rod filter 1 for both inlet and outlet. After being filtered by the first titanium rod filter 1, the material enters the first recovery storage tank 2 through the outlet main pipe 4. Initially, the pressure transmitter readings on the main feed pipe 3 and the corresponding first outlet branch pipe 41 are basically consistent. As filtration proceeds, activated carbon gradually accumulates in the first titanium rod filter 1, and the inlet pressure gradually exceeds the outlet pressure. When the pressure difference reaches a preset value, the controller 11 determines that the titanium rod filter 1 is close to blockage, and then closes its inlet and outlet automatic control valves 5 and opens the automatic control valve 5 of the second titanium rod filter 1 to continue the filtration process. Similarly, when the pressure difference between the inlet and outlet of the second titanium rod filter 1 reaches a preset value, the system automatically switches to the third titanium rod filter 1. This process continues, enabling continuous filtration and preventing system shutdown due to blockage of a single titanium rod filter 1. When the flow switch 8 of the discharge main pipe 4 displays that the flow rate has reached the preset value, it indicates that the filtration has ended. The controller 11 controls all automatic control valves 5 to close, and the material filtration is completed.

[0029] 2. Replacement stage:

[0030] The controller 11 controls the opening of the automatic valve 5 of the displacement liquid feed pipe 9, the closing of the automatic valve 5 of the inlet branch pipe 42 of the first recovery tank 2, and the opening of the automatic valve 5 of the inlet branch pipe 42 of the second recovery tank 2. The displacement liquid enters each titanium rod filter 1 in sequence, displacing the residual product adsorbed in the activated carbon. The displacement liquid enters the second recovery tank 2 through the discharge main pipe 4 for recovery.

[0031] 3. Rinsing stage:

[0032] After the replacement is completed, the controller 11 closes the automatic control valve 5 of the replacement liquid inlet pipe 9 and opens the automatic control valve 5 of the tap water inlet pipe 10, while simultaneously switching the liquid inlet to the third recovery storage tank 2. Tap water sequentially rinses each titanium rod filter 1, and the rinsing wastewater enters the third recovery storage tank 2 for disposal. The rinsing process can effectively reduce the risk of static electricity during subsequent activated carbon extraction.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
