Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to filtration devices. Background Technology

[0002] In material handling processes in chemical, pharmaceutical, and food processing industries, compressed nitrogen is often used as a non-contact conveying power source due to its inertness and resistance to reaction with materials. A compressed nitrogen conveying system typically consists of a high-pressure storage tank, nitrogen delivery pipelines, material storage tanks, and manually controlled valves. By continuously supplying compressed nitrogen into the material storage tanks or delivery pipelines, the pressure difference of the nitrogen propelles powders, granules, or liquids along a pre-set path, thereby achieving the transfer of materials between different production stages.

[0003] In related technologies, filtration devices use compressed nitrogen to transport materials. However, to maintain a stable transport pressure, compressed nitrogen needs to be continuously replenished into the system, resulting in high nitrogen consumption. Furthermore, the transport status of compressed nitrogen relies on manual inspection. Operators need to periodically check the pressure gauge readings to confirm the nitrogen pressure and check for pipeline leaks. Human negligence can easily lead to abnormal pressure, thereby causing transport interruption or equipment overpressure damage. Utility Model Content

[0024] Compressed nitrogen, due to its inertness and resistance to reaction with materials, is often used as a power source for non-contact conveying. A compressed nitrogen conveying system typically consists of a high-pressure storage tank, nitrogen delivery pipelines, material storage tanks, and manually controlled valves. By continuously supplying compressed nitrogen into the material storage tank or delivery pipeline, the pressure difference of the nitrogen propelles powders, granules, or liquids along a predetermined path, thus transferring materials between different production stages. In related technologies, filtration devices use compressed nitrogen to convey materials; however, to maintain a stable conveying pressure, compressed nitrogen must be continuously replenished into the system, resulting in high nitrogen consumption. Furthermore, the conveying status of compressed nitrogen relies on manual inspection. Operators must periodically check pressure gauge readings to confirm nitrogen pressure and check for pipeline leaks. Human error can easily lead to abnormal pressure, causing conveying interruptions or equipment overpressure damage.

[0025] Therefore, such as Figure 1 As shown, the filtration device proposed in this utility model includes: a filter 100, a heating device 200, and a diaphragm pump. The filter 100 has an internal filtration space for holding the material to be filtered. The heating device 200 is connected to the filtration space and provides heat for the filtration process to maintain a suitable temperature for the material and promote filtration efficiency. The outlet of the diaphragm pump is connected to the inlet of the filter 100 via a pipe, providing a stable feed pressure to the filter 100 to ensure continuous material flow within the system. This method eliminates the need for compressed nitrogen gas delivery. Pressure control via the diaphragm pump enables more precise feed adjustment, reducing energy consumption and manual intervention, thereby lowering production costs and improving operational convenience. It is suitable for automated production needs in chemical, pharmaceutical, and food processing industries.

[0026] In some embodiments of this utility model, such as Figure 1As shown, the filter 100 comprises a first chamber 130, a second chamber 140, and a sandwich section 150. Both the first chamber 130 and the second chamber 140 are hemispherical in shape. The sandwich section 150 is disposed between the first chamber 130 and the second chamber 140, and together they form a filtration space. The first chamber 130 and the sandwich section 150 are fixedly connected by multiple first fasteners 160, and the second chamber 140 and the sandwich section 150 are fixedly connected by multiple second fasteners 170. The fasteners are preferably hook screws, ensuring a tight fit between the components and easy disassembly and maintenance. This hemispherical cavity enhances the structural strength of the filter 100 and allows for uniform flow of material within the filtration space, reducing the risk of dead zones or clogging, and further improving filtration accuracy and efficiency. It should be noted that the interlayer 150 is provided with a filter layer, which can be one or more of the following: metal filter screen, non-woven fabric, filter paper, ceramic filter membrane, polymer filter element or sintered porous material, which can adapt to the characteristics of different materials and the requirements of filtration accuracy.

[0027] In some embodiments of this utility model, such as Figure 1 As shown, the heating device 200 can be a steam generator, an electric heater, or a thermal oil circulator, etc., connected to the filtration space through pipelines to form a circulation loop, thereby providing continuous and uniform heat for the filtration process. The steam generator directly or indirectly heats the filtration space by generating high-temperature steam, the electric heater achieves rapid heating using the principle of resistance heating, and the thermal oil circulator transfers heat through circulating thermal oil to ensure stable and controllable temperature. It can be flexibly configured according to the material characteristics and process requirements; for example, a steam generator can be selected when high-temperature filtration is required, or an electric heater can be used when precise temperature control is required.

[0028] In some embodiments of this utility model, such as Figure 1 As shown, the diaphragm pump serves as the feed pressure source. Its outlet is connected to the inlet of the filter 100 via a pipeline, allowing for adjustment of the output pressure according to filtration requirements. The diaphragm pump can be pneumatic or electric, with the output pressure typically controlled between 0.1 MPa and 0.6 MPa. Pneumatic diaphragm pumps utilize compressed air and are suitable for explosion-proof or humid environments, while electric diaphragm pumps rely on electricity and are more suitable for automated control systems. The 0.1 MPa to 0.6 MPa pressure range ensures that the material maintains appropriate flowability and filtration rate during the filtration process, avoiding equipment damage due to excessive pressure or filtration interruption due to insufficient pressure. The use of the diaphragm pump replaces traditional compressed nitrogen delivery, reducing nitrogen consumption and the need for manual monitoring, achieving energy saving and precise pressure control, and improving production efficiency and system reliability.

[0029] In some embodiments of this invention (not shown in the figures), the filtration device further includes a control unit electrically connected to the diaphragm pump for real-time adjustment of the pump's flow rate and output pressure. The control unit can automatically adjust the diaphragm pump's operating state based on sensor feedback or preset parameters, such as increasing the output pressure when filtration resistance increases, or adjusting the pump speed when flow demand changes, thereby maintaining a stable filtration process. This automated control reduces manual intervention by operators, lowers the risk of human error, facilitates timely detection and handling of abnormal situations, improves the device's intelligence level and ease of operation, and meets the modern industrial pursuit of efficient and safe production.

[0030] In some embodiments of this utility model, such as Figure 1 As shown, a pressure gauge 110 and an exhaust valve 120 are installed on the top of the filter 100. The pressure gauge 110 is used to monitor pressure changes inside the filtration space, while the exhaust valve 120 is connected to the filtration space and is used to release accumulated gas when necessary. The pressure gauge 110 provides real-time pressure readings to help operators or control systems understand the filtration status, while the exhaust valve 120 releases gas during system startup or operation, preventing gas resistance from affecting filtration efficiency or causing pressure fluctuations. This ensures the stability and safety of the filtration process, avoids equipment failure or product quality problems caused by abnormal pressure, and reduces downtime for maintenance.

[0031] In some embodiments of this utility model, such as Figure 1 As shown, a support frame 300 is installed at the bottom of the filter 100 to stably support the entire filter 100 structure. The support frame 300 is usually made of metal material and has sufficient strength and corrosion resistance.

[0032] In some embodiments of this utility model, such as Figure 1 As shown, during operation, material is fed into the filtration space of filter 100 through the inlet by a diaphragm pump. Simultaneously, the heating device 200 provides heat according to a set temperature, ensuring the material is filtered under suitable conditions. The control unit adjusts the operation of the diaphragm pump based on data from the pressure gauge 110 and the flow sensor, ensuring that the feed pressure and flow rate always match the filtration requirements. The filtered material is discharged from the outlet, while residues or filter cake remain in the filtration space and can be removed by cleaning or replacing the filter media. The filtration device does not rely on an external nitrogen supply, reducing resource waste and environmental pollution, and improving production efficiency.

[0033] This utility model's filtration device integrates a diaphragm pump, a heating device 200, and an intelligent control unit, avoiding the limitations of traditional nitrogen delivery and achieving an energy-saving, efficient, and automated filtration process. Its simple structure and convenient operation not only reduce production costs and reliance on manual labor but also improve filtration accuracy and system reliability.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
