Description

Technical Field

[0001] The invention relates to the field of ash content testing of coal sample analysis indicators, and in particular to an ash content rapid determination device and a determination method. Background Art

[0002] In the coal industry, ash content is an important indicator for measuring coal quality. Too high ash content will affect the combustion efficiency of coal, reduce the combustion temperature of coal, and the residue produced will also have an impact on the environment. Therefore, accurate and rapid determination of the ash content in coal is of great significance for coal quality control, rational use of coal and environmental protection.

[0003] At present, the common coal ash determination devices on the market mainly use muffle furnaces for combustion determination. However, this method requires that the coal be placed in the device for combustion, and then the ash be taken out of the device for weighing. The operation process is cumbersome, and in the process of taking and placing the coal, some coal may fall or the ash may escape into the air, resulting in inaccurate measurement results. At the same time, due to the lack of effective stirring and heating of the coal, the coal cannot fully contact with the heating device, and the combustion speed is slow, which affects the measurement efficiency.

[0013] As a preferred embodiment of the present invention, a method for rapid determination of ash content specifically comprises the following steps:

[0014] Step 1, first place the coal sample bottle containing the analysis sample on the synchronous belt inside the conveying trough plate, then the synchronous belt works to drive the coal sample bottle to move horizontally backward, after the coal sample bottle moves to just below the bottle cap clamp, the clamping cylinder works to drive the bottle cap clamp to clamp and fix the bottle cap of the coal sample bottle, then the rotating motor works to drive the clamping cylinder and the bottle cap clamp to rotate, so that the bottle cap is detached from the coal sample bottle, and then the coal sample bottle continues to move backward under the synchronous belt inside the conveying trough plate, and at the same time, the robot works to clamp the empty ash dish, and then transfers the ash dish to the top of the weighing balance and places it, and then the moving device 2 drives the vibrator moving plate to move forward, so that the vibrator moving plate drives the piezoelectric straight vibrator and the material channel to move forward, so that the discharge port at the front end of the material channel is located just above the ash dish;

[0015] Step 2: When the coal sample bottle after opening is moved to the coal taking unit, the moving device drives the lifting cylinder and the grabbing claw to move horizontally to the left to the top of the coal sample bottle, and then the lifting cylinder drives the grabbing claw to move downward into the interior of the coal sample bottle, so that the grabbing claw takes samples. After sampling, the lifting cylinder drives the grabbing claw to move upward out of the coal sample bottle, and then the moving device repeatedly drives the grabbing claw to move to the top of the material channel for unloading, so that the material grabbed by the grabbing claw falls into the interior of the material channel;

[0016] Step 3: At this time, the piezoelectric vibrator works to make the material channel vibrate. Under the slight vibration of the material channel, the material slowly falls from the material channel into the ash dish. The weighing balance weighs and records the weight of the ash sample in the ash dish in real time. When the amount of coal sample in the ash dish reaches the weight required for the test, the piezoelectric vibrator stops, and the coal sample feeding action stops at the same time. At this time, the moving device 2 works again to drive the material channel to move backward, so that the front end of the material channel is no longer located above the ash dish. At the same time, the dust suction pipe can smoothly suck away the remaining coal sample in the material channel through the dust suction port;

[0017] Step 4. The robot then works again, driving the grabbing component at its lower end to move to the ash pan and grab the ash pan containing the ash coal sample, then moves to the fast ash continuous measuring instrument, and places the coal sample ash pan on the chain line that conveys the ash pan. At this time, the ash pan is at the right end of the upper surface of the chain line, and then the chain line works to transport the coal sample to the fast ash continuous measuring instrument for ash differentiation. After the treatment, the ash pan will be moved out from the left side of the fast ash continuous measuring instrument, and then the robot grabs the ash pan that has been differentiated again, and moves the ash pan to the weighing scale for weighing. Based on this, the system calculates the ash content of the coal sample, and then the ash pan is sent to the vessel cleaning device for cleaning. Finally, the cleaned ash pan is placed on the positioning placement plate for storage and standby.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) By adopting a special heating device and processing flow, the coal can be burned evenly and quickly, thereby greatly shortening the measurement time and improving the measurement efficiency;

[0020] (2) By providing real-time feedback on the weight of coal and ash, the problem of coal falling or ash escaping that may occur during the traditional method of taking and placing coal is avoided, thereby improving the accuracy of measurement;

The front end of the piezoelectric direct vibrator 504 is provided with a material channel 505, and the material channel 505 is located below the moving device 1 401. The lower end of the vibrator moving plate 503 is connected to the vibrator moving plate 503 through a synchronous belt drive. It is slidably mounted on the frame 1 by a linear guide rail 506; wherein, the setting of two sets of weighing units 5 makes the ash content test based on the average value of double sample tests, and double samples are taken for the test of the same sample. The whole process of testing double samples of one sample is weighed on the same weighing balance 501. The system is equipped with two sets of weighing balances 501, which can speed up the efficiency of ash detection. The material channel 505 is V-shaped, so that during the vibration unloading process of the material channel 505, the material is not easy to scatter from the left and right sides of the material channel 505, so as to avoid the material being scattered around the device at will to affect the working environment and subsequent cleaning work.

The second adjustment cylinder 804 and the third adjustment cylinder 806, and the telescopic ends of the first adjustment cylinder 803, the second adjustment cylinder 804 and the third adjustment cylinder 806 are all provided with push plates 805, and the three push plates 805 are respectively located in front of, on the right side and at the rear of the chain plate line 12, and the right side wall of the mounting frame 201 is provided with a vessel cleaning device 13, which can clean the ash dish 802 after the ashing and weighing are completed, and remove the residue inside the ash dish 802, so as to facilitate the subsequent storage of the ash dish 802; wherein, the upper and lower sides of the chain plate line 12 are provided with push plates 805, and the push plates 805 are respectively ... The upper right end of the ash dish 802 is lower than the upper left end, ensuring that the high temperature area inside the fast ash continuous measuring instrument 7 stays longer, thereby promoting a more thorough ashing process. Since the ashing process needs to be carried out at high temperature, this transportation method can ensure that the material has been fully preheated before reaching the temperature conditions required for ashing, thereby accelerating the speed of the ashing reaction and improving work efficiency. It can also ensure that the material is more evenly distributed in the furnace, avoiding local overheating or overcooling, thereby making the ashing process more uniform and improving the accuracy of the measurement results. The first adjusting cylinder 803, the second adjusting cylinder 804, the third adjusting cylinder 806 and the push plate 805 are set, so that after the robot 6 places the ash dish 802 on the upper surface of the right side of the chain plate line 12, when the placement position of the ash dish 802 is skewed, the ash dish 802 can be adjusted to make the ash dish 802 and the chain plate line 12 in a vertical placement state, and then the chain plate line 12 can stably transport the ash dish 802 to the inside of the fast ash continuous measuring instrument 7. If it is not adjusted, it is easy to fall when it is subsequently transported to the inside of the fast ash continuous measuring instrument 7, affecting the measurement work;

[0040] It should be noted that when the material channel 505 needs to drop materials, the material channel 505 moves the front end discharge port to the middle above the ash dish 802 through the moving device 401, and the bottom of the material channel 505 is very close to the top of the ash dish 802, so that the material channel 505 will not collide with the ash dish 802 during the horizontal movement back and forth, and the material channel 505 will not vibrate the material to the vicinity of the ash dish 802 when it vibrates to drop materials, affecting subsequent inspection and cleaning work.

A dust suction pipe 11 is provided above the material channel 505, and the dust suction pipe 11 is installed on the frame 1 through a dust removal connecting shaft. The setting of the dust suction pipe 11 can suck away excess material inside the material channel 505 to prevent the material from remaining on the material channel 505, resulting in subsequent adhesion or corrosion of the material channel 505 after moisture, thereby affecting the subsequent use effect of the material channel 505. The lower end of the clamp dust hood 10 and the upper end of the dust suction pipe 11 are both connected to the dust collector 9.

[0042] Embodiment 2:

[0043] Please refer to Figure 1 , Figure 2 As shown, the present invention also discloses a method for rapid determination of ash content, which specifically comprises the following steps:

[0044] Step 1: first place the coal sample bottle 203 containing the analysis sample on the synchronous belt inside the conveying slot plate 202, and then the synchronous belt drives the coal sample bottle 203 to move horizontally backward. After the coal sample bottle 203 is transferred to the bottom of the bottle cap clamp 304, the clamping cylinder 303 drives the bottle cap clamp 304 to clamp and fix the bottle cap of the coal sample bottle 203. Then the rotating motor 302 drives the clamping cylinder 303 and the bottle cap clamp 304 to rotate, so that the bottle cap is detached from the coal sample bottle 203. Afterwards, the coal sample bottle 203 continues to move backward under the synchronous belt transfer inside the conveying trough plate 202, while the robot 6 works to clamp the empty ash dish 802, and then transfers the ash dish 802 to the top of the weighing balance 501 for placement, and then the second moving device 502 drives the vibrator moving plate 503 to move forward, so that the vibrator moving plate 503 drives the piezoelectric direct vibrator 504 and the material channel 505 to move forward, so that the discharge port at the front end of the material channel 505 is located directly above the ash dish 802;

[0045] Step 2, when the coal sample bottle 203 after opening the cover moves to the coal taking unit 4, the moving device 401 works to drive the lifting cylinder 402 and the grabbing claw 403 to move horizontally to the left to the top of the coal sample bottle 203, and then the lifting cylinder 402 drives the grabbing claw 403 to move downward into the interior of the coal sample bottle 203, so that the grabbing claw 403 takes samples, and after sampling, the lifting cylinder 402 drives the grabbing claw 403 to move upward out of the coal sample bottle 203, and then the moving device 401 drives the grabbing claw 403 to move to the top of the material channel 505 for unloading, so that the material grabbed by the grabbing claw 403 falls into the interior of the material channel 505;

[0046] Step 3, at this time, the piezoelectric vibrator 504 works to make the material channel 505 vibrate. Under the slight vibration of the material channel 505, the material slowly falls from the material channel 505 into the ash dish 802. The weighing balance 501 weighs and records the weight of the ash sample in the ash dish 802 in real time. When the amount of coal sample in the ash dish 802 reaches the weight required for the test, the piezoelectric vibrator 504 stops, and the coal sample feeding action stops at the same time. At this time, the moving device 2 502 works again to drive the material channel 505 to move backward, so that the front end of the material channel 505 is no longer located above the ash dish 802. At the same time, the dust suction pipe 11 works to smoothly suck away the remaining coal sample in the material channel 505 through the dust suction port;

[0047] Step 4, the robot 6 then works again, driving the grabbing component at its lower end to move to the ash pan 802 and grab the ash pan 802 containing the ash coal sample, and then moves to the quick ash continuous measuring instrument 7, and places the coal sample ash pan 802 on the chain plate line 12 that conveys the ash pan 802. At this time, the ash pan 802 is at the right end of the upper surface of the chain plate line 12, and then the chain plate line 12 works to transport the coal sample to the quick ash continuous measuring instrument 7 for ash differentiation treatment. After the treatment, the ash pan 802 will be moved out from the left side of the quick ash continuous measuring instrument 7, and then the robot 6 grabs the ash pan 802 after ash differentiation again, and moves the ash pan 802 to the weighing balance 501 for weighing. Based on this, the system calculates the ash content of the coal sample, and then the ash pan 802 is sent to the vessel cleaning device 13 for cleaning treatment. Finally, the cleaned ash pan 802 is placed on the positioning placement plate 801 for storage and standby.

8. A method for rapid determination of ash content, characterized in that: The specific steps include: Step 1: first place the coal sample bottle (203) containing the analysis sample on the synchronous belt inside the conveying slot plate (202), and then the synchronous belt drives the coal sample bottle (203) to move horizontally backward. After the coal sample bottle (203) is transferred to the bottom of the bottle cap clamp (304), the clamping cylinder (303) drives the bottle cap clamp (304) to clamp and fix the bottle cap of the coal sample bottle (203). Then the rotating motor (302) drives the clamping cylinder (303) and the bottle cap clamp (304) to rotate, so that the bottle cap is detached from the coal sample bottle (203). The rear coal sample bottle (203) continues to move backward under the synchronous belt inside the conveying trough plate (202), and at the same time, the robot (6) works to clamp the empty ash dish (802), and then transfers the ash dish (802) to the top of the weighing balance (501) for placement, and then the moving device 2 (502) drives the vibrator moving plate (503) to move forward, so that the vibrator moving plate (503) drives the piezoelectric direct vibrator (504) and the material channel (505) to move forward, so that the discharge port at the front end of the material channel (505) is located directly above the ash dish (802); Step 2: When the coal sample bottle (203) is opened and moves to the coal taking unit (4), the moving device (401) drives the lifting cylinder (402) and the grabbing claw (403) to move horizontally to the left to the top of the coal sample bottle (203), and then the lifting cylinder (402) drives the grabbing claw (403) to move downward into the interior of the coal sample bottle (203), so that the grabbing claw (403) can take samples. After sampling, the lifting cylinder (402) drives the grabbing claw (403) to move upward out of the coal sample bottle (203), and then the moving device (401) drives the grabbing claw (403) to move to the top of the material channel (505) for unloading, so that the material grabbed by the grabbing claw (403) falls into the interior of the material channel (505); Step 3: At this time, the piezoelectric vibrator (504) works to vibrate the material channel (505). Under the slight vibration of the material channel (505), the material slowly falls from the material channel (505) into the ash dish (802). The weighing balance (501) weighs and records the weight of the ash sample in the ash dish (802) in real time. When the amount of coal sample in the ash dish (802) reaches the weight required for the test, the piezoelectric vibrator (504) stops, and the coal sample feeding action stops at the same time. At this time, the moving device 2 (502) works again to drive the material channel (505) to move backward, so that the front end of the material channel (505) is no longer located above the ash dish (802). At the same time, the dust suction pipe (11) works to smoothly suck away the remaining coal sample in the material channel (505) through the dust suction port; Step 4: Then the robot (6) starts working again, driving the grabbing component at its lower end to move to the ash dish (802) and grab the ash dish (802) containing the ash content coal sample, and then moves to the quick ash continuous measuring instrument (7), and places the coal sample ash dish (802) on the chain plate line (12) that conveys the ash dish (802). At this time, the ash dish (802) is at the right end of the upper surface of the chain plate line (12), and then the chain plate line (12) works to transport the coal sample to the inside of the quick ash continuous measuring instrument (7) for ash content. After the ash is decomposed, the ash dish (802) is moved out from the left side of the quick ash continuous measuring instrument (7). Then the robot (6) grabs the ash dish (802) that has been decomposed again and moves the ash dish (802) to the weighing scale (501) for weighing. Based on this, the system calculates the ash content of the coal sample. Then the ash dish (802) is sent to the dish cleaning device (13) for cleaning. Finally, the cleaned ash dish (802) is placed on the positioning plate (801) for storage and standby use.
