Description

Technical Field

[0001] The present application relates to the technical field of coal washing and coal storage and transportation, and in particular to a coal sludge water cleaning system under a belt conveyor. Background Art

[0002] Coal transportation is an extremely important task in the coal production process. Coal transportation methods mostly use conveyor belt conveyors and conveyor scraper conveyors. Among them, conveyor belt conveyors are the most widely used due to their high production efficiency, stable and reliable operation, continuous and uniform transportation, low noise during operation, simple structure, low operating cost, easy maintenance, easy to realize automatic control and remote operation, etc., and are suitable for coal transportation under various conditions.

[0003] During operation, due to the moisture and stickiness of the coal, a certain amount of coal slime will adhere to the working surface of the belt conveyor when it is making the return motion. Although there are various types of cleaners in the coal industry to remove the coal slime on the return belt, the cleaners cannot be used in all scenarios. Therefore, the coal slime on the belt conveyor still needs to be cleaned manually.

The implementations described in the following embodiments do not represent all implementations consistent with the present application.

[0019] Coal transportation is an extremely important task in the coal production process. Coal transportation methods mostly use conveyor belt conveyors and conveyor scraper conveyors. Among them, conveyor belt conveyors are the most widely used due to their high production efficiency, stable and reliable operation, continuous and uniform transportation, low noise during operation, simple structure, low operating cost, easy maintenance, easy to realize automatic control and remote operation, etc., and are suitable for coal transportation under various conditions.

[0020] During operation, due to the moisture and stickiness of the coal, a certain amount of coal slime will adhere to the working surface of the belt conveyor when it is making the return motion. Although there are various types of cleaners in the coal industry to remove the coal slime on the return belt, the cleaners cannot be used in all scenarios. Therefore, the coal slime on the belt conveyor still needs to be cleaned manually. The coal slime falling to the ground under the belt conveyor will increase the workload and may even cause safety hazards.

[0021] Some embodiments of the present application provide a coal slime water cleaning system under a belt conveyor, including a coal slime water guiding mechanism and a coal slime water treatment mechanism;

[0022] The coal slime water guiding mechanism is arranged below the belt conveyor, and the coal slime water treatment mechanism is connected to the outlet of the coal slime water guiding mechanism;

[0023] The coal slurry water guiding mechanism comprises a water retaining weir 1, an auxiliary flushing water nozzle 3 and a first control device; the auxiliary flushing water nozzle 3 is electrically connected to the first control device; the water retaining weir 1 is arranged directly below the return belt of the belt conveyor, and the water retaining weir 1 contains the coal slurry adhered to the return belt;

[0024] The coal slurry water treatment mechanism includes a coal slurry water treatment pit 6, a pit impurity removal part 8, a second control device 9 and a slurry pump 10; the pit impurity removal part 8 is connected to the outlet of the coal slurry water guiding mechanism; the second control device 9 is electrically connected to the slurry pump 10, and the second control device 9 and the slurry pump 10 are arranged in the coal slurry water treatment pit 6.

[0025] The coal slurry water guiding mechanism described in the present application is located below the return belt of the belt conveyor. The coal slurry water guiding mechanism is composed of a water retaining weir 1 as a main part, which restricts the coal slurry water inside the water retaining weir 1 and allows the coal slurry water to flow toward the coal slurry water treatment mechanism.

[0026] In order to solve the problem of insufficient fluidity of coal slurry water, an auxiliary flushing water nozzle 3 is arranged above the water retaining weir 1, and the auxiliary flushing water nozzle 3 is controlled by the first control device.

[0027] The coal slurry water first flows into the pit impurity removal part 8 of the coal slurry water treatment system, and then flows into the coal slurry water treatment pit 6. When the coal slurry water is stored to a certain height, the second control device 9 controls the slurry pump 10 to process the coal slurry water.

[0028] In some embodiments, the first control device includes a solenoid valve 4 and a time-controlled switch 5 , and the solenoid valve 4 is electrically connected to the time-controlled switch 5 .

[0029] The solenoid valve 4 is controlled by the time-controlled switch 5 to open the auxiliary flushing water nozzle 3 to release high-pressure water, thereby enhancing the fluidity of the coal slurry water.

[0030] In some embodiments, a filter 7 is further provided at the outlet of the pit cleaning section 8, and the filter 7 may be a cleaning grate.

[0031] Before the coal slurry water enters the coal slurry treatment pit, a debris removal grate is set to remove large particles that cannot be processed by the slurry pump 10.

[0032] In some embodiments, the second control device 9 is a water level sensor.

[0033] The water level is monitored by the second control device 9, and when the water level reaches a preset height, the slurry pump 10 is started to pump the coal slurry water to the coal slurry water centralized water tank.

[0034] Among them, the coal slurry water treatment pit 6 is designed with a closed end. The upper end of the pit is large and the lower end is contracted to the strong suction range of the slurry pump feed port, ensuring that the slurry pump can fully work on the coal slurry water.

[0035] In some embodiments, the slurry pump 10 is installed in the coal slurry water treatment pit 6 through a hanging chain 11.

[0036] The utility model makes full use of the fluidity of the coal slime water itself, and arranges an auxiliary flushing water nozzle 3 to enhance the fluidity of the coal slime water and simultaneously uses high-pressure flushing to solve the stubborn problem of coal slime adhesion.

[0037] The working principle of the coal sludge water cleaning system under the belt conveyor provided in this application is explained below in conjunction with the accompanying drawings.

[0038] like Figure 1 and Figure 2 As shown, the coal slurry water guiding mechanism is arranged below the return working surface of the belt conveyor and is responsible for conveying the coal slurry water below the belt conveyor to the coal slurry water treatment mechanism, and the coal slurry water treatment pit 6 is responsible for treating the coal slurry water.

[0039] like Figure 1 As shown, the water retaining weir 1 is arranged around the return working surface of the belt conveyor, which is responsible for confining the coal slime 2 in a fixed area to prevent overflow. At the same time, the auxiliary flushing water nozzle 3 sprays high-pressure water to enhance the fluidity of the coal slime 2 and make the coal slime flow to the coal slime water treatment part.

[0040] like Figure 1 As shown, the time switch 5 is responsible for controlling the electromagnetic valve 4 to open and close regularly to release the high-pressure water in the auxiliary flushing water nozzle 3 to impact the coal slime 2, thereby breaking up the stubborn bonding part of the coal slime 2 and enhancing the fluidity of the coal slime 2 to ensure that the coal slime water flows smoothly into the coal slime water treatment part.

[0041] like Figure 2 As shown, the coal slurry water transported by the coal slurry water guiding mechanism first enters the pit impurity removal section 8, and then enters the coal slurry water treatment pit 6 after being filtered by the filter 7 in the pit impurity removal section 8.

[0042] like Figure 2 As shown, the coal slurry water enters the coal slurry water treatment pit 6 and is stored and accumulated. The water level of the coal slurry water in the coal slurry water treatment pit 6 continues to rise. When the water level rises to a certain height, the second control device 9 starts the slurry pump 10 to drain the coal slurry water. After the coal slurry water is drained, the slurry pump 10 stops working and the operation cycle is completed.

[0043] It can be seen from the above embodiments that the present application provides a coal slurry water cleaning system under a belt conveyor, including a coal slurry water guiding mechanism and a coal slurry water treatment mechanism; the coal slurry water guiding mechanism is arranged below the belt conveyor, and the coal slurry water treatment mechanism is connected to the outlet of the coal slurry water guiding mechanism; the coal slurry water guiding mechanism includes a water retaining weir, an auxiliary flushing water nozzle and a first control device; the auxiliary flushing water nozzle is electrically connected to the first control device; the water retaining weir is arranged directly below the return belt of the belt conveyor, and the water retaining weir contains the coal slurry adhered to the return belt; the coal slurry water treatment mechanism includes a coal slurry water treatment pit, a pit impurity removal part, a second control device and a slurry pump; the pit impurity removal part is connected to the outlet of the coal slurry water guiding mechanism; the second control device is electrically connected to the slurry pump, and the second control device and the slurry pump are arranged in the coal slurry water treatment pit. The present application arranges an auxiliary flushing water nozzle above the water retaining weir, and the auxiliary flushing water nozzle is controlled by the first control device to open and release high-pressure water at a fixed time to enhance the fluidity of the coal slurry water. The slurry pump is controlled by the second control device. When the material in the coal slurry water treatment pit is stored to a certain height, the slurry pump starts working. After the coal slurry water treatment is completed, the slurry pump stops working. The intermittent working mode of the slurry pump ensures that the slurry pump can work safely and avoids damage to the slurry pump caused by overload or no load.
