[0002] In ore dressing (coal) plants, concentration detection is often done manually using a concentration pot, which is labor-intensive and requires not only manual weighing but also manual table lookup. Concentration measurement is seriously delayed, and the concentration obtained after manual weighing and table lookup cannot reflect the concentration of the slurry in the current production system, because the concentration of the slurry in the production system changes in real time, resulting in many disadvantages in the use of concentration pots in production.

[0049] In this embodiment, there are at least two types of slurry concentration meters, namely a first slurry concentration meter and a second slurry concentration meter. The first slurry concentration meter and the second slurry concentration meter have the same structure, but their installation methods are different.

[0050] See also Figure 2 The first slurry concentration meter includes a first probe 810, a first control board 820, and a first wireless module 830. The first probe 810 is used to detect the slurry concentration in the first inner tube 711 of the first pipeline 710, and transmit the detected electrical signal to the first control board 820, which amplifies, filters, and converts the signal into a digital signal, and then transmits it to the first wireless module, and then transmits it to the router through the first wireless module, and finally transmits it to the third wireless module through the router, and then the corresponding information can be read and stored by the PC;

[0051] The first slurry concentration meter of this embodiment is directly connected in series to the first pipeline 710, such as the slurry concentration meter of model DD-DF-6420 sold by Beijing Jinyang Wanda Technology Co., Ltd.

[0052] See also Figure 3 The second slurry concentration meter includes a second probe 840, a second control board 850, and a second wireless module 860. The second probe 840 is used to detect the slurry concentration in the second inner tube 721 of the second pipeline 720, and transmit the detected electrical signal to the second control board 850, which amplifies, filters, and converts the signal into a digital signal, and then transmits it to the second wireless module, and then transmits it to the router through the second wireless module, and finally transmits it to the third wireless module through the router, and then the corresponding information can be read and stored by the PC;

[0053] The first probe 810 and the first control board 820, the second probe 840 and the second control board 850 can directly use the detection part and the circuit part of the existing slurry concentration meter (completed digital slurry concentration meter), such as the detection part and the control part of the existing ion concentration meter (see the H26907 ultrasonic slurry concentration meter sold by Beijing Hengaode Instrument Co., Ltd.).

[0054] The first pipeline and the second pipeline in this embodiment are at least used to illustrate different installation positions, which may be different positions of the same pipeline or positions corresponding to different pipelines.

[0055] See also Figure 4-Figure 10 The control box has a third wireless module 320, a router 330, a main control board 310, and a power switch 340 built in. The main control board 310 is equipped with a controller and a memory. The controller can be a PLC, MCU, CPU, etc.; the memory is used to store data and can be a hard disk.

[0056] The power input end of the power switch 340 is conductively connected to the power source, and the power output end is conductively connected to each electrical device, so that the power switch 340 can control the current of each electrical device. In this embodiment, the power switch 340 is a knife switch.

[0057] The memory is communicatively connected to the first signal terminal of the controller, the second signal terminal of the controller is communicatively connected to the third wireless module 320, and the third wireless module is networked with the first wireless module and the second wireless module through a router.

[0058] When in use, the controller controls the third wireless module 320 to collect data transmitted to the router by the first wireless module and the second wireless module through the router, and then stores it through the memory, and compares it through the built-in program of the controller. Once it is found that it exceeds the preset threshold, an alarm message is sent to the PC to alert the operator.

[0059] Control instructions can also be sent to the first control board and the second control board of the first slurry concentration meter and the second slurry concentration meter through the main control board 310 and the PC to collect the slurry concentration of a specific period of time or return the slurry concentration of a specific period of time.

[0060] The control box includes a box body 200 and a box door 100. The interior of the box body 200 is a hollow electrical cavity 201, and a router 330, a third wireless module 320, a main control board 310, and a power switch 340 are installed in the electrical cavity 201. The electrical cavity 201 is open at one end facing the box door 100, and this opening is closed by the box door 100; the controller is communicatively connected with the third wireless module.

[0061] The door 100 is hingedly assembled with the box body 200 at one end facing the electrical cavity 201 through a hinge 230, and a locking block is arranged on the other end. The locking block includes two locking block fixing plates 110, one end of the two locking block fixing plates 110 is connected and fixed through a locking block connecting plate 120, and a locking bevel 130 is respectively fixed on the inner side of the other end. The locking bevel 130 is provided with a tightening bevel 131 and a locking groove 132. The tightening bevel 131 is arranged from top to bottom, from an end away from the locking block connecting plate 120 to an end close to the locking block connecting plate 120. The locking groove 132 is engaged with the locking rod 611, so as to lock the locking block, that is, to lock the door 100 on the box body 200.

[0062] A locking block through groove 111 is formed between the end surfaces of the two locking bevel blocks 130 that are close to each other, and a locking strip sliding groove 112 is formed between the end surfaces of the two locking bevel blocks 130 that are provided with the locking groove 132, the end surface of the locking block connecting plate 120, and the inner side surfaces of the two locking block fixing plates 110;

[0063] The locking rod 611 is fixed on the locking bar 610, and the locking bar 610 is engaged with the locking bar sliding groove 112 and can be slidably assembled in the length direction;

[0064] Trigger plates 620 are fixed to both ends of the lock bar 610 , respectively. The lock bar 610 is also provided with a tooth groove 612 , which can mesh with the gear 650 for transmission, thereby forming a gear rack transmission mechanism.

[0065] The gear 650 is fixed at one end of the output shaft 641, and the other end of the output shaft 641 is installed in the door lock motor 640, and the door lock motor 640 can drive the output shaft to rotate forward and reverse in the circumferential direction. The door lock motor 640 is installed in the motor slot 633, and the motor slot 633 is set on the power block 630. The power block 630 is also provided with a gear slot 632 and a lock bar slot 631. The gear 650 is installed in the gear slot 632, and the lock bar slot 631 and the lock bar 610 can be slidably assembled; the power block is fixed on the inner wall of the electrical cavity.

[0066] The two trigger plates 620 are respectively opposite to the travel assembly in the length direction of the lock bar. The travel assembly includes a guide cylinder 510, a travel switch 520, and a first travel fixing plate 530. The guide cylinder 510 has a hollow guide inner cylinder 511 inside. One end of the travel switch 520 is a limit end 521. The limit end 521 is installed in the guide inner cylinder 511 and can slide in the axial direction of the guide cylinder.

[0067] The other end of the travel switch 520 passes through the first travel fixing plate 530 and faces the trigger plate 620 close to it. A spring 550 is installed in the guide cylinder 510. The spring 550 is used to generate an elastic force that hinders the switch 520 from moving toward the guide cylinder. The first travel fixing plate 530 is fixed on the inner wall of the electrical cavity 201.

[0068] One end of the guide cylinder of one of the travel components away from the travel switch 520 is assembled and fixed to the fixed boss 560, and the fixed boss 560 is fixed on the inner wall of the electrical cavity 201;

[0069] The end of the guide cylinder of the other stroke assembly away from the stroke switch 520 is assembled and fixed to the guide support plate 540 , and the guide support plate 540 is fixed on the inner wall of the electrical cavity 201 .

[0070] The door lock motor 640 is controlled by a motor driver, and the power input wire of the motor driver is connected to the output terminal of the power switch 450. The power input terminal of the power switch 450 is conductively connected to an external power source, which can be AC ​​power or a battery.

[0071] The control end of the motor driver is communicatively connected to the third signal end of the controller, so that the controller can send a control instruction to the motor driver to control the operating state of the door lock motor 640.

[0072] The fourth signal terminal and the fifth signal terminal of the controller are also respectively connected to two travel switches for communication. When the travel switch is triggered, the travel switch is closed, so that the controller obtains a signal input.

[0073] See also Figure 6 In this embodiment, the upper travel switch is called the first travel switch and the lower travel switch is called the second travel switch. When the door 100 is locked, the second travel switch is triggered, and the locking rod 611 is engaged with the locking groove 132, so that the door 100 cannot be opened.

[0074] When the door 100 needs to be opened, the controller sends a control instruction to the motor driver, so that the door lock motor drives the lock bar to move toward the first travel switch through the gear until the first travel switch is triggered, and then the door lock motor stops running. At this time, the lock rod is separated from the lock slot, so that the door can be opened.

[0075] When the door needs to be locked, the door lock motor drives the gear to reverse, thereby driving the lock bar to move toward the second travel switch. During this process, the lock rod first contacts the tensioning slope 131, thereby pulling the door 100 toward the box body 200 through the tensioning slope 131, which makes the door and the end face of the box body close together. Finally, the lock rod is engaged with the lock slot, and the second travel switch is triggered at this time, and the door lock motor stops running.

[0076] Preferably, the opening end of the electrical cavity 201 is further provided with a sealing groove 202, in which a sealing strip 220 is installed, and the box door 100 is pressed against the sealing strip 220 to achieve a seal between the box door and the box body, so as to prevent water or dust from entering the electrical cavity. During the locking process, the box door is pulled toward the box body by the action of the locking rod and the tightening inclined surface 131, thereby squeezing the sealing strip to obtain a better sealing effect.

[0077] When in use, the external device sends control instructions to the controller through the third wireless module, thereby controlling the motor to open and close the door. This design has high security, which can prevent others from accidentally opening the electrical cavity, and also prevent others from modifying the internal equipment or adjusting its internal parameters after opening the electrical cavity to avoid monitoring and cause unnecessary losses.

[0078] The wireless modules (first wireless module, second wireless module, third wireless module) of this embodiment can be selected from 4G module, WIFI module, ZigBee module, Bluetooth module and the like.

[0079] The signal end of this embodiment only refers to the corresponding pins, and the first, second, third, etc. are only described as different pins. During specific implementation, the corresponding pins need to be selected according to the functions recorded in this embodiment and the corresponding pin definitions.
