Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a filter with intelligent monitoring function, which can be applied to water treatment, industrial filtration, air purification and other fields. Background Technology

[0002] Filters, as liquid separation devices used to control impurities in industrial processes, are widely used in industries such as pharmaceuticals, food, and beverages. Traditional filters typically achieve their filtration function through physical interception or adsorption, but they suffer from the following problems: 1. The condition of the filter element needs to be checked manually periodically, and it is impossible to monitor blockage or failure in real time; 2. Lack of data recording and analysis functions makes it difficult to predict filter lifespan; 3. Fault alarms rely on human experience, resulting in a delayed response.

[0003] Although some filters in the existing technology are equipped with pressure sensors, their monitoring functions are limited and they are not integrated with intelligent data processing modules, making it impossible to achieve comprehensive condition assessment. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent filter that can monitor the filtration status in real time, automatically issue early warnings, and record data, thereby solving the problem of traditional equipment relying on manual maintenance.

[0005] This utility model proposes a filter with intelligent monitoring function, comprising a sealed upper shell and a tank, a replaceable filter element disposed inside the tank, and an inlet pipe and an outlet pipe connected to both ends of the tank; a first pressure sensor and a second pressure sensor are respectively installed in the inlet pipe and the outlet pipe to detect the outlet pressure difference, and a flow sensor is installed at the end of the outlet pipe to check the real-time flow rate; a control unit and a human-machine interface are provided on the outer wall of the tank, the control unit including a microprocessor for calculating the filter element clogging index, a ferroelectric memory for storing historical data, and an audible and visual alarm; the human-machine interface includes a touch screen for displaying operating parameters and a wireless communication module; A flow sensor is installed in the middle of the outlet pipe; The inner wall of the tank is provided with an electromagnetic shielding layer with a thickness of 0.3-0.7mm.

[0006] As a preferred technical solution of this utility model, the water quality sensor is integrated into the tank to detect pH value, turbidity or particulate matter concentration.

[0007] As a preferred technical solution of this utility model, the filter element has a built-in RFID tag that communicates with the control unit. The control module automatically identifies the filter element model and matches the life algorithm. The algorithm calculates the remaining life (remaining life = 1 - actual flow rate / rated flow rate) by accumulating the filtration volume in real time through the flow sensor and comparing it with the rated value, and then compares it with the water pressure difference between the inlet and outlet.

[0008] As a preferred technical solution of this utility model, the low-power LoRa / NB-IoT wireless communication is adopted to adapt to industrial Internet of Things scenarios.

[0009] As a preferred technical solution of this utility model, the electromagnetic shielding layer is provided on the inner wall of the tank, and a 0.5mm thick aluminum coating is used to improve the signal-to-noise ratio of the sensor by 40%.

[0010] The beneficial effects of this utility model are as follows: 1. Enables full lifecycle monitoring of filter cartridge status, reducing the risk of sudden malfunctions; 2. Reduce maintenance costs through accurate lifespan prediction; 3. Supports remote management and is compatible with smart home scenarios. Attached Figure Description

Detailed Implementation

[0012] Example 1 (Water Filter): The filter housing is made of 304 stainless steel. The differential pressure sensor has a range of 0-1MPa and an accuracy of ±1%. The water quality sensor detects residual chlorine and TDS values. When the differential pressure exceeds 0.3MPa or the flow rate is lower than 70% of the rated value, a replacement reminder is triggered.

[0013] like Figures 1 to 2As shown, this utility model proposes a filter with intelligent monitoring function, including a sealed upper shell and a tank, a replaceable filter element disposed inside the tank, and an inlet pipe and an outlet pipe connected to both ends of the tank. A first pressure sensor and a second pressure sensor are respectively installed inside the inlet pipe and the outlet pipe to detect the outlet pressure difference. A flow sensor is installed at the end of the outlet pipe to check the real-time flow rate. A control unit and a human-machine interface are provided on the outer wall of the tank. The control unit includes a microprocessor for calculating the filter element clogging index, a ferroelectric memory for storing historical data, and an audible and visual alarm. The human-machine interface includes a touch screen for displaying operating parameters and a wireless communication module. A flow sensor is installed in the middle of the outlet pipe; The inner wall of the tank is provided with an electromagnetic shielding layer with a thickness of 0.3-0.7mm; The filter element has a built-in RFID tag that communicates with the control unit.

[0014] Working principle: Water flows into the tank through the inlet pipe, passes through a replaceable filter to intercept impurities, and is then output through the outlet pipe. The first and second pressure sensors monitor the pressure difference between the two ends in real time, and the flow sensor at the end of the water pipe provides real-time flow data. The microprocessor of the control unit dynamically calculates the filter clogging index based on the pressure difference change rate and flow data, and records historical operating parameters through a ferroelectric memory. When the pressure difference exceeds the preset threshold or reaches a critical value, the control unit triggers an audible and visual alarm to remind the user to clean or replace the filter.

[0015] The flow sensor continuously monitors the outflow rate and combines it with differential pressure data to generate the percentage of remaining filter life, which is displayed in real time via a touch screen. When the filter life is less than 10%, the system pushes a replacement reminder via the touch screen and simultaneously sends an alarm message to the user's mobile phone via the wireless communication module. Users can view real-time data such as differential pressure, flow curve, and filter life through the touch screen, and manually adjust alarm thresholds or initiate emergency cleaning. Ferroelectric memory supports retrieving historical operation records, facilitating the analysis of the long-term performance of the filtration system.

[0016] Through multi-sensor collaboration and intelligent algorithm optimization, this solution significantly outperforms traditional differential pressure control filters in terms of cleaning trigger accuracy and user experience. The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
