Description

Technical Field

[0001] The utility model relates to the technical field of coal hopper anti-blocking and dredging devices, in particular to a coal hopper anti-blocking and dredging device for a car dumper. Background Art

[0002] The coal hopper of the car dumper is a key component in the car dumper system. It plays an important role in the unloading, transportation and subsequent processing of coal. Since the inner wall of the coal hopper is made of inclined cast stone slabs, coal with high water content and wet stickiness can easily accumulate on the inner wall, causing coal slime to stick to the wall and blockage. Coal with small particles and density can easily be scattered in the coal hopper, causing coal accumulation. Coal with poor fluidity can easily accumulate at the coal hopper outlet, causing coal blockage and coal scattering. Therefore, it is necessary to add an anti-coal scattering vibration dredging device to the coal hopper of the car dumper to ensure the normal operation of the equipment. Utility Model Content

[0013] (1) The anti-blocking and unblocking device for the coal hopper of the car tipper is equipped with a coal hopper body of the car tipper, an air storage tank, a controller, a blowing rod, a blowing head, and an electromagnetic valve. The air storage tanks are evenly arranged on the outer wall of the coal hopper body of the car tipper. Compressed air of a certain pressure is stored in the air storage tank. When the coal hopper body of the car tipper is blocked, the compressed air is instantly released and ejected at high speed by opening the electromagnetic valve. This powerful airflow is ejected through the blowing head on the blowing rod on the inner wall of the coal hopper body of the car tipper, impacting the blocked coal material, causing it to be subjected to strong impact and vibration, thereby breaking the blockage, restoring the fluidity of the coal material, and reducing the blockage and coal overflow in the coal hopper.

It determines whether the main body of the coal hopper of the dumper is blocked by the contact between the blades and the material. When the main body of the coal hopper of the dumper is normal, the blades can rotate freely. When the main body of the coal hopper of the dumper is blocked, the blades are hindered by the coal material and cannot rotate. At this time, the torque sensor transmits a signal to the controller, and the controller controls the solenoid valve to automatically open through the wireless communication module, and controls the compressed air in the air tank to enter the blowing rod, which is conducive to automatically monitoring the condition of the main body of the coal hopper of the dumper.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides an embodiment: a dumper coal hopper anti-blocking and dredging device, including a dumper coal hopper main body 1, an air storage tank 4, a controller 5 and a blowing rod 7. The outer side of the dumper coal hopper main body 1 is evenly provided with air storage tanks 4 through a bracket 8, and the inner side wall of the dumper coal hopper main body 1 is evenly distributed with blowing rods 7.

The solenoid valves 3 are electrically connected to the controller 5, and the opening and closing of the solenoid valves 3 are controlled by the controller 5.

[0024] Furthermore, in order to ensure the blowing effect, an air pump is installed on the connection path between the air guide pipe 9 and the air storage tank 4. The air pump is also electrically connected to the controller. The air pump cooperates with the solenoid valve 3 to ensure the blowing effect.

[0025] Furthermore, the blowing heads 6 are evenly distributed on the blowing rod 7; there are 6 groups of blowing heads 6 on the blowing rod 7, and 3 groups of blowing nozzles 15 are provided on the blowing heads 6. The number of blowing heads 6 and blowing nozzles 15 can also be adjusted according to actual usage, and can be arranged in a matrix of multiple groups.

[0026] Further, refer to Figure 3 A main channel 13 is provided at one end of the interior of the blowing head 6, and the main channel 13 is evenly connected to the blowing nozzle 15 through the secondary channel 14, which is conducive to expanding the blowing range of the air.

[0027] Furthermore, the blowing nozzles 15 are all provided with air outlets 16, and the air outlets 16 all adopt a conical structure with a conical angle of 45° to 75°, preferably 60°, which can better compress the gas, thereby increasing the jet speed and improving the impact effect on the coal.

[0028] Furthermore, a cover 17 is provided on the outside of the injection nozzle 15 to protect the injection nozzle 15 and prevent the injection nozzle 15 from being blocked by the pulverized coal.

[0029] Furthermore, a rotating shaft 11 is installed inside the dumper coal hopper body 1, near the side wall of the hopper. A drive motor 21 is installed on one side of the top of the dumper coal hopper body 1 via a fixed plate 10. The output end of the drive motor 21 is connected to the rotating shaft 11. The bottom end of the rotating shaft 11 is provided with a blade 12 to detect and determine whether the pulverized coal in the hopper is blocked. A torque sensor 2 is installed inside the drive motor 21, and the output end of the torque sensor 2 communicates with the controller 5 via a wireless communication module 18. The contact between the blade 12 and the coal is used to determine whether the dumper coal hopper body 1 is blocked. When the dumper coal hopper body 1 is normal, the blade 12 can rotate under the action of the drive motor 21. When the dumper coal hopper body 1 is blocked, the blade 12 is blocked by the coal and cannot rotate. At this time, the torque sensor 2 transmits a signal to the controller 5, which controls the solenoid valve 3 to automatically open, facilitating automatic monitoring of the dumper coal hopper body 1 and reducing coal blockage and bulging in the hopper.

[0030] See also Figure 4 and 5 The controller 5 is installed on one side of the coal hopper body 1 of the dumper, and a circuit board is provided inside the controller 5.

The central chip 19 is Siemens S7-300 / 6ES7321-1BL00-0AA0 or Siemens S7-200 series. The appropriate model is selected according to the actual use environment.

[0031] A shielding layer 20 is provided on the inner side wall of the controller 5 , and the shielding layer 20 is woven with metal wires to reduce the controller 5 from external electromagnetic interference.

[0032] The specific models and specifications of the above-mentioned drive motor 21, torque sensor 2, solenoid valve 3, wireless communication module 18 and central chip 19 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is existing technology, so it will not be described in detail.

[0033] Working principle: When the present application is in use, the shaft 11 and blades 12 arranged inside the coal hopper body 1 of the dumper rotate. The contact between the blades 12 and the coal and the rotational resistance of the blades 12 are converted into the torque of the shaft to judge whether the coal hopper body 1 of the dumper is blocked. When the coal hopper body 1 of the dumper is operating normally, the blades 12 can rotate under the action of the drive motor 21 and serve as a stirring device; when the coal hopper body 1 of the dumper is blocked, the blades 12 are hindered by the coal and cannot rotate. At this time, the torque sensor 2 transmits a signal to the controller 5, and the controller 5 controls the solenoid valve 3 to automatically open through the wireless communication module 18, so that the compression The air is released instantly and ejected at high speed. The powerful airflow is ejected upward through the blowing head 6 on the blowing rod 7 on the inner wall of the coal hopper body 1 of the dumper, impacting the blocked coal material and subjecting it to strong impact and vibration, thereby breaking the blockage and restoring the fluidity of the coal material, which is beneficial to automatically monitor the situation of the coal hopper body 1 of the dumper and reduce the blockage and loosening of coal in the coal hopper; in addition, three groups of blowing nozzles 15 are provided on the blowing head 6, which are beneficial to expand the blowing range of the air, and at the same time, air outlets 16 are provided on the blowing nozzles 15. The air outlets 16 are all conical structures, which can better compress the gas, thereby increasing the jet speed and improving the impact effect on the coal material.
