Description

Technical Field

[0001] This utility model relates to the field of mechanical milling equipment technology, and in particular to a control system for a wet milling production line. Background Technology

[0002] Currently, quartz sand production mainly employs two methods: wet grinding and dry grinding. While dry grinding offers significant energy advantages, the resulting powder contains more impurities that are difficult to separate. Wet grinding primarily uses two methods: water milling and ball milling. The former has lower output, while the latter consumes more energy and has higher production costs. Furthermore, in existing production lines, all controls are implemented via control panels with buttons, resulting in low information density, a large operating surface, and a mechanical display layout that is ergonomically inefficient and prone to errors.

[0003] Chinese patent (patent application number 202011461768.0) discloses a "wet preparation method and production line for high-purity quartz sand." This method and production line includes coarse crushing-screening, fine crushing-screening, magnetic separation, scrubbing, flotation, gravity separation, and dewatering. These steps can be connected to form an automated continuous production line, achieving continuous and efficient production of quartz sand. Furthermore, in this application, the fine crushing-screening, magnetic separation, scrubbing, flotation, and gravity separation processes are all carried out in a slurry state, constituting a wet sand-making process. This reduces energy consumption and environmental pollution. In addition, this application controls the slurry concentration in each stage of the wet sand-making process to ensure the treatment effect at each stage. Through multi-stage magnetic separation, multi-stage flotation, and gravity separation, the impurity content of the quartz sand can be reduced to less than 50 ppm, and further reduced to less than 30 ppm.

[0004] Another Chinese patent (patent application number 202021101895.5) discloses a "quartz sand production line," which includes a ore washing and sorting system, a storage system, a sand making system, and a water circulation system. The sand making system includes a fine crushing line, a screening mechanism, a secondary treatment line, and a drying line. The fine crushing line is connected to the ore washing and sorting system. The screening mechanism is equipped with a finished product outlet and a defective product outlet. The defective product outlet is connected to the input end of the secondary treatment line. Both the secondary treatment line and the finished product outlet are connected to the input end of the drying line. The water circulation system includes an acid supply device, a regulating tank, and a sludge treatment unit. The acid supply device is connected to the ore washing and sorting system. The input end of the sludge treatment unit is connected to the regulating tank. The sludge treatment unit supplies purified wastewater to the acid washing line, the rinsing and sorting line, and the secondary treatment line through pipelines. This quartz sand production line can reuse defective minerals and wastewater in the quartz sand production process, reducing production costs.

[0005] Another Chinese patent (patent application number 202022989580.5) discloses a "wet production line for high-purity quartz sand preparation." This production line includes a coarse crushing unit, a rod mill unit, a magnetic separator unit, a scrubbing machine, multiple flotation units, a gravity separation device, and a dewatering treatment device. These devices can be connected in series to form an automated continuous production line, achieving continuous and efficient production of quartz sand. In this production line, the material is processed in a slurry state through the rod mill unit, magnetic separator unit, scrubbing machine, multiple flotation units, and gravity separation device, thus employing a wet sand-making process. This reduces energy consumption and environmental pollution. Furthermore, this application controls the slurry concentration at each stage of the wet sand-making process, ensuring the processing effect at each stage. Through multi-stage magnetic separation, multi-stage flotation, and gravity separation, the impurity content of the quartz sand can be reduced to less than 50 ppm, and further reduced to less than 30 ppm.

[0006] Another Chinese patent (patent application number 202210180677.2) discloses a "Data-Driven Intelligent Production Control System for Quartz Sand," which includes a control module, a weighing module, and an alarm module. The weighing module includes a screening component and a weighing component. The screening component is located at the output port of the discharge conveyor to screen the quartz sand after cold-cold treatment. The weighing component weighs the quartz sand that does not meet the volume requirements and sends the weighing data to the control module. The control module includes a comparison unit that receives the weighing data sent by the weighing component and compares it with a standard value. If the weighing data is greater than the standard value, the control module sends an alarm signal to the alarm module, which then issues an alarm notification upon receiving the alarm signal. This application has the advantage of reducing the probability of poor cold-cold treatment of quartz sand.

[0007] Another Chinese patent (patent application number 202122235314.8) discloses a "novel intelligent control system for a crusher," which employs a technical solution including: a microcontroller unit and a crusher motor control module and a feeder motor control module connected to the microcontroller unit. The crusher motor control module is used to control the rotation of the crusher motor, and the feeder motor control module is used to control the rotation of the feeder motor. The microcontroller unit sends crushing command parameters to the crusher motor control module, and the crusher motor control module sends motor control signals according to the crushing command parameters to control the opening or closing of the first AC contactor and the second AC contactor. The opening or closing of the first AC contactor and the second AC contactor controls the forward or reverse rotation of the crusher motor. Summary of the Invention

[0077] The start-up process of the equipment involved in the wet milling production line control system of this embodiment (i.e., the order of start-up) is shown in the appendix. Figure 2 As shown, the sequence is as follows: water spray device → sixth conveyor belt → second dewatering screen → magnetic separator → separation tower → second conveyor pump → safety screen → first conveyor pump → vibrating screen → fourth conveyor belt → roller mill → third conveyor belt → transfer silo → second conveyor belt → cone crusher → first conveyor belt → jaw crusher → fifth conveyor belt → first dewatering screen. The stopping process (i.e., the order of stopping) is the reverse of the starting process (i.e., the opposite order).

[0078] When using manual control, first switch all device switches to the start / stop position, then follow the start procedure described above, pressing the start / stop switches of the corresponding devices in sequence. To stop, press the start / stop switches of the corresponding devices in reverse order.

[0079] When using centralized control, all devices must first be switched to the signal conversion module position via their selector switches. Then, operation can be performed directly on the industrial control computer. For touchscreen devices, the start button can be clicked directly on the interface; for non-touchscreen devices, a mouse click is used. The industrial control computer, following a pre-programmed start procedure, sends start commands sequentially to the signal conversion modules of each device via the industrial router. Each device's control unit is then activated via its selector switch, initiating the start-up process and achieving one-button start for the entire line. Similarly, to stop, the stop button is clicked. The industrial control computer, following a pre-programmed stop procedure, sends stop commands sequentially to the signal conversion modules of each device via the industrial router. Each device's control unit is then deactivated via its selector switch, initiating the stop process and achieving one-button stop or emergency stop for the entire line. When a single device on the line needs to be paused, the industrial control computer can select the device to be stopped. The industrial router then sends a stop command to the selected device's signal conversion module, which is transmitted to the device's control unit via its selector switch, cutting off the device's power supply and stopping that single device. During the entire production line process, the operating data of each piece of equipment is transmitted to the industrial control computer through its signal conversion module and industrial router, and is automatically saved in the storage component of the industrial control computer.

[0080] The following section uses a jaw crusher as an example to explain in detail the working process of starting and stopping a jaw crusher independently.

[0081] When using manual control, first switch the jaw crusher selector switch to the jaw crusher start / stop switch position. Then, press the jaw crusher start / stop switch (i.e., the start button). At this time, the jaw crusher start / stop switch sends a start signal to the jaw crusher's own control unit through the jaw crusher selector switch. Upon receiving the signal, the jaw crusher's own control unit immediately controls the jaw crusher to start. When it is necessary to stop, press the jaw crusher start / stop switch (i.e., the stop button). At this time, the jaw crusher start / stop switch sends a stop signal to the jaw crusher's own control unit. Upon receiving the signal, the jaw crusher's control unit immediately controls the jaw crusher to stop.

[0082] When using centralized control mode, first switch the jaw crusher selector switch to the jaw crusher signal conversion module position. Then, select the single-device (jaw crusher control interface) control interface on the industrial control computer's control panel. After clicking the start button on the jaw crusher control interface, the industrial control computer immediately sends a jaw crusher start signal, which is transmitted to the jaw crusher signal conversion module via the industrial router. The jaw crusher signal conversion module receives the start signal (digital signal) from the industrial control computer, converts it into an analog signal, and transmits it to the jaw crusher's own control components via the jaw crusher selector switch. Upon receiving the analog signal, the jaw crusher's control components immediately control the jaw crusher to start. The stopping process is similar and will not be described further.

[0083] The starting and stopping of other devices are similar to those described above, and will not be repeated here.

[0084] In this embodiment, when the wet milling production line control system operates, the ore (such as quartz, dolomite, etc.) raw material enters the jaw crusher for coarse crushing. The coarsely crushed material is conveyed by the first conveyor belt to the cone crusher for fine crushing. The finely crushed material is then conveyed by the second conveyor belt to the transfer silo for temporary storage. The finely crushed material in the transfer silo is conveyed by the third conveyor belt to the roller mill for fine roller milling. The fine powder from the roller mill is conveyed by the fourth conveyor belt to the vibrating screen (equipped with a water washing nozzle) for washing, separating the ore powder from the mud into a mixture. This mixture is then conveyed by the first conveyor pump to the safety screen for coarse and fine separation. Here, the material is divided into two streams: one stream contains coarse material, which falls into the screen under gravity. The first dewatering screen at the bottom of the column dewaters the material. After dewatering, the coarse material is transported to the intermediate storage bin via the fifth conveyor belt. The other path is that the mixture after separating the coarse material is transported to the separation tower by the second conveyor pump for mud-powder separation. The separated mud-water enters the tail powder bin at the bottom of the separation tower for sedimentation under gravity. The separated ore powder enters the magnetic separator at the bottom of the separation tower for magnetic separation under gravity. Magnetic materials (such as iron powder) contained in the ore powder are attracted by the magnets in the magnetic separator (which are removed periodically). After magnetic separation, the ore powder enters the second dewatering screen at the bottom of the magnetic separator for dewatering under gravity. After dewatering, it becomes the finished product and is transported to the finished product bin for storage by the sixth conveyor belt.

[0085] The control system for the wet powder production line of this utility model is matched with the wet powder production line and is suitable for preparing mineral powders including quartz sand powder, dolomite powder and calcium carbonate powder.
