Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0028] The core of the present invention is to provide a blanking device cleaning mechanism to realize the automation of blanking device cleaning, so as to avoid problems such as low efficiency, great harm and incomplete cleaning existing in manual cleaning.

[0030] The blanking device cleaning mechanism provided by the present invention includes a fixing plate 1. A clamping device 3 for clamping and fixing the blanking device 8 is provided on the fixing plate 1, and a rotating device 2 for driving the clamping device 3 to rotate. Above the clamping device 3 on the fixing plate 1, there is an upper cleaning device 5 for blowing high-pressure air towards the discharge port 82 of the blanking device 8, and a first telescopic device 4 for driving the upper cleaning device 5 to move relative to the clamping device 3. Below the clamping device 3 on the fixing plate 1, there is a lower cleaning device 6 for blowing high-pressure air towards the feed port 81 of the blanking device 8, and a second telescopic device 7 for driving the lower cleaning device 6 to move relative to the clamping device 3.

[0031] Among them, the fixing plate 1 is the installation carrier of the entire mechanism. The fixing plate 1 is in a plate-like structure. Of course, the fixing plate 1 can also be of other shapes. The blanking device 8 is the object to be cleaned. The blanking device 8 includes a feed port 81 and a discharge port 82, and the feed port 81 is larger than the discharge port. The feed port 81 is in a flared shape. The clamping device 3, the rotating device 2, the upper cleaning device 5 and the lower cleaning device 6 are regularly distributed on the fixing plate 1.

[0032] The clamping device 3 is installed on the rotating device 2 and can rotate together with the rotating device 2. The clamping device 3 is used to clamp and fix the blanking device 8 so that the upper cleaning device 5 and the lower cleaning device 6 can clean the blanking device 8.

[0033] The upper cleaning device 5 is connected to the first telescopic device 4, and the upper cleaning device 5 is located above the clamping device 3 so that the upper cleaning device 5 can send high-pressure gas from top to bottom into the discharge port 82 of the blanking device 8, thereby blowing away the pulverized coal on the inner wall of the blanking device 8. The first telescopic device 4 can drive the upper cleaning device 5 to move so that the upper cleaning device can approach the blanking device 8 for cleaning, or the upper cleaning device 5 can move away from the blanking device 8 so that the lower cleaning device 6 can clean the blanking device 8.

[0034] The lower cleaning device 6 is connected to the second telescopic device 7, and the lower cleaning device 6 is located below the clamping device 3, so that the lower cleaning device 6 sends high-pressure gas into the feed port 81 of the blanking device 8 from bottom to top, thereby blowing away the pulverized coal on the inner wall of the blanking device 8. The second telescopic device 7 can drive the lower cleaning device 6 to move, so that the lower cleaning device approaches the blanking device 8 for cleaning, or the lower cleaning device 6 moves away from the blanking device 8 so that the upper cleaning device 5 can clean the blanking device 8.

[0035] During use, the blanking device 8 to be cleaned can be sent to the clamping device 3 by a manipulator or an automated device. The manipulator or the automated device withdraws, the clamping device 3 clamps the blanking device 8, the rotating device 2 rotates to make the discharge port 82 of the blanking device 8 face upward, and the first telescopic device 4 drives the upper cleaning device 5 to extend, so that the upper cleaning device 5 presses on the discharge port 82 of the blanking device 8 and continuously blows in high-pressure gas to blow away the pulverized coal on the inner wall of the blanking device 8. Then, the first telescopic device 4 drives the upper cleaning device 5 to retract.

[0036] Since the upper cleaning device 5 blows high-pressure air flow from top to bottom, most of the pulverized coal in the blanking device 8 can be blown away. However, the distance between the discharge port 82 and the feed port 81 is relatively far, and the discharge port 82 is in a horn shape. Therefore, there is still pulverized coal remaining on the inner wall of the discharge port 82 and inside the blanking device 8.

[0037] The second telescopic device 7 drives the cleaning device to approach the blanking device 8, so that the lower cleaning device 6 blows high-pressure gas into the feed port 81 of the blanking device 8 to blow away the pulverized coal remaining at the inlet and inside of the blanking device 8 by the high-speed air flow. After the cleaning of the feed port 81 of the blanking device 8 is completed, the second telescopic device 7 drives the cleaning device away from the blanking device 8, the rotating device 2 rotates and resets, the clamping device 3 opens, the manipulator or the automated device enters the cover assembly to take out the blanking device 8, and the cleaning of the blanking device 8 is completed.

[0038] The blanking device cleaning mechanism provided by the present invention clamps and fixes the blanking device 8 with the clamping device 3, the rotating device 2 drives the clamping device 3 to rotate to make the discharge port 82 of the blanking device 8 face upward, the first telescopic device 4 drives the upper cleaning device 5 to approach the blanking device 8, the second telescopic device 7 drives the lower cleaning device 6 away from the blanking device 8, and the upper cleaning device 5 blows high-pressure air flow into the discharge port 82 of the blanking device 8 from top to bottom, thereby blowing away most of the pulverized coal in the blanking device 8. After the cleaning of the upper cleaning device 5 is completed, the first telescopic device 4 drives the upper cleaning device 5 away from the blanking device 8, the second telescopic device 7 drives the lower cleaning device 6 to approach the blanking device 8, and the lower cleaning device 6 blows high-pressure gas into the feed port 81 of the blanking device 8 from bottom to top, thereby blowing away the pulverized coal remaining on the inner wall and inside of the feed port 81, ensuring thorough cleaning of the blanking device 8 and not affecting the next experimental result. Moreover, the automation of cleaning is realized, the work efficiency is improved, no manual intervention is required, and it is harmless to people.

[0042] On the basis of the above embodiments, considering the specific connection manner of the clamping cylinder 33, as a preference, a mounting plate 9 is fixed on the positioning plate 32, and the clamping cylinder 33 is mounted on the mounting plate 9. Of course, the mounting plate 9 can also be fixedly connected to the support plate 31.

[0043] On the basis of the above embodiments, considering the specific setting manner of the rotating device 2, as a preference, the rotating device 2 includes a turntable 21 and a rotating cylinder for driving the turntable 21 to rotate. The rotating cylinder is fixedly connected to the fixing plate 1, and the outer end face of the turntable 21 is arranged parallel to the fixing plate 1. The support plate 31 is mounted on the outer end face of the turntable 21.

The upper connector 53 is used for connecting to a high-pressure air pipe, and the high-pressure air pipe is used for conveying high-pressure gas to the cleaning head 51. Specifically, the high-pressure air pipe can be connected to a high-pressure air pump or an air storage tank, etc., to convey high-pressure gas to the cleaning head 51, and then blow it into the discharge port 82 of the blanking device 8 through the cleaning holes 52.

In order to control the cleaning head 51 to approach the blanking device 8 and make the cleaning hole 52 press the discharge port 82 of the blanking device 8, or control the cleaning head 51 to stay away from the blanking device 8.

Specifically, the high-pressure air pipe can be connected to a high-pressure air pump or a gas storage tank, etc., to deliver the high-pressure gas to the lower joint 62, and then blown into the feed port 81 of the dropper 8 by the high-pressure nozzle 61.

[0049] The high-pressure nozzle 61 can be driven by the second telescopic device 7 to extend into the feed port 81 of the dropper 8 so as to thoroughly flush the inner wall of the dropper 8. Specifically, after the high-pressure nozzle 61 driven by the second telescopic cylinder slowly rises to the first position, the high-pressure nozzle 61 driven by the second telescopic cylinder slowly descends to the second position, and then the high-pressure nozzle 61 driven by the second telescopic cylinder slowly rises to the first position again. After the high-pressure nozzle 61 is repeatedly raised and lowered several times under the drive of the second telescopic cylinder, the feed port 81 of the dropper 8 and the coal powder inside can be completely blown away, further improving the thoroughness of cleaning the dropper 8.
