[0021] like Figure 1-7As shown, a novel feed filtration device for an ultra-high pressure filtration system includes a main body 1. An inspection door 2 is located on one side of the upper end of the main body 1, and a feed inlet 5 is located on the other side of the upper end of the main body 1. An exhaust port 4 is positioned in the middle of the upper end of the main body 1, and a base 3 is positioned at the bottom of the main body 1. A partition 16 is installed in the middle of the interior of the main body 1. A valve 15 is installed inside the main body 1 at the feed inlet 5. A grate 18 is engaged with the inner side of the partition 16 and the inner side of the main body 1. A flow monitor 11 and a concentration meter 11 are installed inside the main body 1 at the feed inlet 5. The flow rate monitor 12 and the impurity monitor 14 are installed in the inner gap of the grate plate 18. The flow area monitoring sensor 17 is installed in the gap of the grate plate 18. The flow rate monitor 11, the concentration monitor 12 and the impurity monitor 14 are all connected to the control box 13. The slurry of the ultra-high pressure filter feed is initially detected and the data such as flow rate and concentration are fed back to the intelligent center. This avoids the blind feeding situation of traditional feeding and realizes real-time monitoring of feeding. According to the main impurities in the material that may affect product quality or even damage the filter cloth during the production process, the grate is classified, identified and removed, realizing the efficiency and targeted grate removal.

[0022] The upper inner side of the partition 16 is also equipped with a fixing block 20, and the side of the grate 18 is equipped with a locking bracket 21, which is locked onto the upper end of the fixing block 20.

[0023] Furthermore, a base 3 is installed at the bottom of the main body 1, a reinforcing rib 6 is positioned on the outer ring of the main body 1, a discharge plate 7 is provided on the bottom side of the main body 1, and a discharge hole 19 is opened on the bottom outer ring of the main body 1. A water tank 10 is installed at the top of the main body 1 above the grate plate 18, a flushing valve 9 is connected to the bottom of the water tank 10, and a flushing head 8 is positioned at the bottom of the flushing valve 9.

[0024] The partition 16 is welded and fixed to the fixing block 20, and the grate 18 is engaged between the main body 1 of the device and the fixing block 20 and the partition 16 by the engaging bracket 21.

[0025] The bottom of the device body 1 is fixed by the base 3. The device body 1 and the discharge hole 19 are integrally formed. The flushing valve 9 controls the water source inside the water tank 10 to be sprayed through the position of the flushing head 8.

[0026] The flow monitor 11, concentration monitor 12 and impurity monitor 14 respectively monitor the flow rate, concentration and impurities of the feed at the feed inlet 5, and transmit the data to the control box 13, so that the valve 15 can be opened and closed.

[0027] Working Principle: This utility model includes a main body 1, an inspection door 2, a base 3, an exhaust port 4, a feed port 5, reinforcing ribs 6, a discharge plate 7, a flushing head 8, a flushing valve 9, a water tank 10, a flow monitor 11, a concentration monitor 12, a control box 13, a debris monitor 14, a valve 15, a partition 16, a flow area monitoring sensor 17, a grate 18, a discharge hole 19, a fixing block 20, and a locking bracket 21. It performs preliminary testing on the slurry fed into the ultra-high pressure filter press and feeds back data such as flow rate and concentration to the intelligent center, avoiding the blind feeding situation of traditional feeding and realizing real-time monitoring of feeding. Based on the main impurities in the material that may affect product quality or even damage the filter cloth during production, it classifies, identifies, and removes them, achieving efficient and targeted grate removal.

[0028] Incoming material inspection

[0029] The slurry of ultra-high pressure filter feed is initially tested, and data such as flow rate and concentration are fed back to the intelligent center.

[0030] This avoids the "blind feeding" situation of traditional feeding and enables real-time monitoring of feeding.

[0031] Debris comb

[0032] Impurities in the coal slurry are classified and removed by a grate. Large pieces and flocculent impurities are removed without affecting the flow of coal slurry. At the same time, the accumulation of impurities removed by the grate is fed back to the intelligent center in real time, and the intelligent center makes real-time judgments and adjustments.

[0033] This method solves the problem of traditional feeding methods that either "don't grab" or "only grab large ones." It classifies and removes major impurities in the materials during production that may affect product quality or even damage the filter cloth, thus achieving efficient and targeted grate removal.

[0034] Cleaning up debris

[0035] Based on the results from the monitoring and control system, the intelligent center issues instructions to clean up debris. The system automatically cleans up the debris through appropriate settings and, as needed, sets up emergency stop instructions to prevent subsequent losses.

[0036] This solves the problems of impurities filling the box, slurry overflow, or grate failure in traditional feeding methods.

[0037] Feed monitoring device

[0038] Setting up the feed pipeline

[0039] Automatic valves are controlled by on / off signals and connected to the centralized control system. During normal feeding, the valve is in the open state. When the filter press system finishes feeding, the valve automatically closes. When impurities are detected in the feed, the valve automatically closes and the filter system stops feeding.

[0040] Online flow meters record and monitor real-time flow, while automatically accumulating the feed volume over a period of time.

[0041] The online concentration meter records the real-time concentration of the slurry. If the slurry is too thick or too thin, the signal is automatically fed back to the central control system, the automatic feed valve closes, and the filtration system stops feeding.

[0042] Debris monitoring

[0043] The impurities in the slurry are mainly coarse particles or large clumps.

[0044] Sensors are installed on the grate in the filtration system to monitor the effective flow area of ​​the grate in real time. When the slurry contains impurities and the effective filtration area of ​​the grate drops to the warning value, an alarm signal is sent to the central control system, the automatic feed valve closes, and the filtration system stops feeding.

[0045] Cleaning up debris

[0046] After the filtration system stops feeding, the central control system issues a command to clean up debris. The maintenance door of the filtration device opens automatically, the grate pops out and flips to remove debris, then the grate returns to the silo, the maintenance door closes automatically, the flushing water valve opens to clean the grate, and then the feeding system starts. After the effective filtration area of ​​the grate is tested and found to be qualified, the debris cleaning is completed.

[0047] Control Center

[0048] This filtration system features centralized control with an independent control cabinet, enabling interlocked operations for feeding, slurry monitoring, debris monitoring, and debris removal. The above description illustrates the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made without departing from the spirit and scope of this invention, and all such changes and modifications fall within the scope of the claims.
