Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an automatic adjustment device for an antimony ore filter press with intelligent pressure feedback. Background Technology

[0002] A filter press is a traditional solid-liquid separation device, mainly used for filtration and dewatering or extracting filtrate. It consists of multiple filter plates and frames stacked together to form a filter chamber, and uses pressure as the driving force for filtration to achieve solid-liquid separation. It is widely used in chemical, environmental protection and other fields. Filter presses play a key role in the antimony ore beneficiation process, mainly for dewatering antimony concentrate, reducing the moisture content of the filter cake, facilitating transportation and smelting. It can also be used to treat fine tailings or mud after antimony ore flotation, achieving solid-liquid separation and wastewater reuse.

[0003] Traditional filter presses rely heavily on manual operation during the separation and pressing of filter plates. Manual intervention is not only labor-intensive, but also makes it difficult to guarantee the accuracy of operation. This can easily lead to situations where the plates are not pulled into place or the pulling speed is inconsistent, resulting in uneven arrangement of filter plates and affecting the subsequent filtration effect. At the same time, manual operation cannot adjust the equipment operating parameters in real time according to the actual production situation, making the production process inflexible. Utility Model Content

The control component includes a control cabinet, a regulating component for controlling equipment operation, an LCD display for displaying operating data, and a monitoring component for monitoring the operating status. The components include a PLC controller for receiving and sending instructions, intermediate relays for controlling the start and stop of the equipment, and a frequency converter for controlling the feed rate of the material conveying component. At least four intermediate relays are provided. The monitoring components include a photoelectric encoder and limit switch for monitoring the position of the plate pulling component, a photoelectric sensor for positioning the filter plate, a first electrical contact pressure gauge for monitoring the hydraulic pressure of the hydraulic component, a second electrical contact pressure gauge for monitoring the conveying pressure of the material conveying component, and a time relay for adjusting the duration of the plate pulling component. The output of the monitoring components is connected to the input of the PLC controller, and the output of the PLC controller is connected to an LCD display.

[0006] Preferably, the moving component includes a servo motor fixed to the plate pulling carriage, a gear located in the inner cavity of the plate pulling carriage, a toothed plate fixed to the filter press, and a guide rail.

The electromagnetic directional valve is installed on the surface of the hydraulic cylinder.

[0009] Preferably, the conveying assembly is located at the other end of the filter press. The conveying assembly includes a feed pump for conveying slurry and a feed pipe for connecting the filter press and the feed pump. One end of the feed pipe is connected to the outlet of the feed pump, and the other end of the feed pipe is connected to the inlet of the filter press.

[0010] Preferably, the control cabinet includes a cabinet body and a cabinet door connected to the cabinet body by hinges, the liquid crystal display is fixed to the upper end of the cabinet body cavity, and an observation window is provided on the upper end of the cabinet door surface.

[0011] Preferably, the output of the PLC controller is also connected to an intermediate relay and a frequency converter, the output of the frequency converter is connected to a feed pump, and the output of the intermediate relay is connected to the input of a servo motor, a hydraulic oil pump, a solenoid directional valve, and a feed pump.

The first electrical contact pressure gauge of the monitoring assembly monitors the hydraulic pressure of the hydraulic assembly, and the second electrical contact pressure gauge monitors the conveying pressure of the material conveying assembly. When the pressure exceeds the set range, the PLC controller receives the signal and adjusts the hydraulic oil pump and the feed pump through intermediate relays and frequency converters to ensure that the filter press operates under appropriate pressure, thereby improving the solid-liquid separation effect. The frequency converter can accurately control the feed amount of the material conveying assembly according to the operating status of the filter press and the pressure feedback, so as to avoid the filter effect being affected by too much or too little feed. The intermediate relays control different equipment respectively to ensure accurate and reliable start and stop of the equipment. The PLC controller can flexibly adjust the control strategy according to different working conditions, so that the filter press operates more stably and accurately. Attached Figure Description

[0036] In this embodiment, the control cabinet 510 includes a cabinet body 511 and a cabinet door 512 connected to the cabinet body 511 by a hinge. The liquid crystal display 530 is fixed to the upper end of the inner cavity of the cabinet body 511, and an observation window is provided on the upper end of the surface of the cabinet door 512.

These sensors can accurately obtain the position information of the plate pulling assembly 200 and transmit the data to the PLC controller 521 to ensure accurate plate pulling position and avoid plate pulling failure. The PLC controller 521 of the control component 520 receives the data from the monitoring component 540 and sends instructions to the intermediate relay 522 and the frequency converter 523 according to the actual situation.

[0040] The technical principle of this utility model is as follows: The hydraulic component 300 starts working, the hydraulic oil station 310 provides hydraulic oil, and the hydraulic oil pump 320 delivers the hydraulic oil to the solenoid directional valve 340. The solenoid directional valve 340 adjusts the oil inlet direction, causing the hydraulic cylinder 330 to actuate, pressing the filter plate to form a filter chamber, preparing for subsequent solid-liquid separation. The first electrical contact pressure gauge 543 monitors the hydraulic pressure of the hydraulic component 300 and transmits the data to the PLC controller 521 to monitor the hydraulic status in real time. The material conveying component 4... The feed pump 410 of the filter press 100 is started, and the antimony ore slurry is transported to the filter chamber of the filter press 100 through the feed pipe 420. The second electrical contact pressure gauge 544 monitors the conveying pressure of the conveying component 400 and feeds the data back to the PLC controller 521. The PLC controller 521 adjusts the feed rate of the feed pump 410 according to the pressure condition through the frequency converter 523 to ensure stable and safe feeding. The filter press 100 uses the filter chamber to perform solid-liquid separation on the antimony ore slurry that is transported in, separating the liquid and solid.

[0041] After solid-liquid separation is completed, the plate-pulling assembly 200 starts working. The servo motor 231 of the moving assembly 230 drives the gear 232 to rotate. The gear 232 meshes with the toothed plate 233, causing the plate-pulling carriage 210 to move along the guide rail 234. The photoelectric encoder 541 monitors the rotation of the servo motor 231, the limit switch 545 determines the position of the plate-pulling carriage 210, and the photoelectric sensor 542 positions the filter plate pull to ensure that the plate-pulling carriage 210 accurately reaches the designated position.

When the plate-pulling trolley 210 reaches its position, the mechanical claw 220 separates the filter plate, facilitating the discharge of solid materials. The LCD display 530 displays the operating data of the entire device, allowing operators to monitor the equipment status in real time. The PLC controller 521 receives data from the monitoring component 540, analyzes and processes it, and then controls the start-stop and operation status of the servo motor 231, hydraulic oil pump 320, electromagnetic reversing valve 340, and feed pump 410 through the intermediate relay 522, thereby achieving automatic adjustment and intelligent control of the entire device.
