[0027] like Figures 1 to 6As shown, a pulverized coal feeding device for high-purity synthesis gas production in an embodiment of the present disclosure is shown, comprising a base plate 1, a material conveying fan 2, a feeding pipe, a suction piece, a transmission housing 3, a support frame 4, a tooth plate 5, an adjustment mechanism, a driven gear 6 and a screwing piece. Compared with the prior art, in this embodiment, the automatic feeding of pulverized coal on the ground is realized through the cooperation of the material conveying fan 2, the feeding pipe and the suction piece, and the staff does not need to manually feed the pulverized coal, which reduces the staff's work intensity and improves work efficiency. The cooperation of the tooth plate 5 and the adjustment mechanism realizes the adjustment of the suction height of the suction piece, so that the suction piece can absorb coal powder at different heights, thereby improving the flexibility of the device. Through the cooperation of the transmission housing 3, the adjustment mechanism and the driven gear 6, the adjustment of the deflection angle of the suction piece is realized, so that the suction piece can absorb coal powder at different positions on the ground, increasing the suction range of the suction piece. Through the twisting piece, the suction piece is swung, so that the suction piece can absorb coal powder at different positions on the ground, further increasing the suction range of the suction piece.

[0028] like Figure 1 and Figure 2 As shown, the material conveying fan 2 is arranged on the upper side of the base plate through a support platform, the output end of the material conveying fan 2 is connected to a feeding pipe, and the input end of the material conveying fan 2 is connected to a feeding pipe, and a suction piece is inserted into the inside of the feeding pipe. The suction piece includes a suction pipe 101, a suction head 102 and a sleeve 103, and the suction head 102 is flat in shape. When the material conveying fan 2 is running, it can absorb the coal powder on the ground into the inside through the feeding pipe and the suction piece, and then transport it to the production equipment through the feeding pipe, thereby realizing the automatic feeding of the coal powder on the ground. A universal brake wheel 7 is installed on the lower side of the base plate 1, and the staff can move the entire device through the universal brake wheel 7, so that the coal powder on the ground can be fed more efficiently.

[0029] like Figures 1 to 3 As shown, the transmission housing 3 is mounted on the outside of the suction member through the first rotating shaft, and the first rotating shaft is rotatably mounted inside the transmission housing 3. Two support frames 4 are mounted on the upper side of the bottom plate 1, and a tooth plate 5 is vertically mounted on the support frame 4 on one side of the two sides, as shown in FIG. Figure 3 and Figure 4As shown, the lifting mechanism is arranged on the support frame 4 on one of the two sides, the lifting mechanism includes a first transmission seat 201, a first motor 202 and a transmission gear 203, the lifting mechanism can drive the suction piece to lift and lower through the transmission shell 3, thereby realizing the adjustment of the suction height of the suction piece, the adjustment mechanism is arranged on the support frame 4 on one of the two sides, the adjustment mechanism includes a second transmission seat 301, a first transmission shaft 302, a first driving gear 303 and a second motor 304, the adjustment mechanism can drive the suction piece to deflect through the transmission shell 3, thereby realizing the adjustment of the suction angle of the suction piece, the lifting mechanism and the adjustment mechanism are both rotatably connected to the transmission shell 3 through the second rotating shaft, the second rotating shaft on one of the two sides is sleeved with a driven gear 6, and the screwing piece is rotatably arranged on the upper side of the transmission shell 3, as shown Figure 5 As shown, the twisting member includes a transmission rod 401 and a twisting disk 402. The twisting member can drive the suction member to swing, thereby realizing the adjustment of the swing angle of the suction member. The suction member is set inside the transmission housing 3 through the first rotating shaft, and is mounted on the support frame 4 through the lifting mechanism and the adjustment mechanism, thereby realizing the installation adjustment of the suction member.

[0030] like Figure 5 As shown, an elastic positioning mechanism is provided on the transmission housing 3, and the elastic positioning mechanism includes a vertical plate 501, a spring pin 502, a mounting frame 503 and a positioning ball 504. A positioning groove is provided on the twisting disk 402, and the diameter of the positioning groove is adapted to the diameter of the positioning ball 504. The positioning ball 504 can be snapped into the inside of the positioning groove, thereby realizing the positioning of the twisting disk 402. The elastic positioning mechanism can position the twisting part, thereby ensuring the stability of the twisting part after twisting, and ensuring the stability of the suction part after swinging.

[0031] like Figure 3 and Figure 6 As shown, a deflection mechanism is provided on the suction member, which includes a gear ring 601, a vertical plate 602, a second transmission shaft 603, a second driving gear 604 and a third motor 605. In this embodiment, the first motor 202, the second motor 304 and the third motor 605 are all forward and reverse motors. When the second driving gear 604 inside the deflection mechanism rotates, it can drive the suction pipe 101 to rotate through the gear ring 601 sleeved on the suction pipe 101, thereby realizing the adjustment of the deflection angle of the suction pipe 101, which is convenient for the staff to absorb the coal powder.

[0032] Working principle: when it is necessary to feed the coal powder on the ground, the staff moves the device to the corresponding position through the universal brake wheel 7, aligns the suction head 102 with the coal powder that needs to be fed, and then starts the material conveying fan 2. The material conveying fan 2 operates to suck the coal powder into its interior through the feed pipe and the suction piece, and then transports it to the production equipment through the feed pipe, thereby realizing the automatic feeding of the coal powder. During the feeding process, when it is necessary to adjust the height of the suction piece, the first motor 202 is started, and the first motor 202 drives the transmission gear 203 to crawl along the tooth plate 5. The transmission gear 203 drives the first transmission base 201 to rise and fall through the first motor 202, and the first transmission base 201 drives the suction member to rise and fall through the second rotating shaft and the transmission housing 3, thereby realizing the adjustment of the suction height of the suction member. When the deflection angle of the suction member needs to be adjusted, the second motor 304 is started, and the second motor 304 drives the first driving gear 303 to rotate through the first transmission shaft 302, and the first driving gear 303 drives the driven gear 6 to rotate, and the driven gear 6 drives the suction member to deflect through the second rotating shaft and the transmission housing 3, thereby realizing the deflection of the suction member. Angle adjustment: When it is necessary to adjust the swing angle of the suction piece, the staff rotates the twisting disk 402, and the twisting disk 402 drives the sleeve 103 to swing through the transmission rod 401, so that the sleeve 103 drives the suction head 102 to swing through the suction pipe 101, thereby realizing the adjustment of the swing angle of the suction piece. During the rotation of the twisting disk 402, the positioning ball 504 can be pushed to move outward, and the positioning ball 504 drives the spring pin 502 to be stretched. When the twisting disk 402 stops rotating, the positioning ball 504 can be clamped to the twisting disk 402 under the action of the spring pin 502. 02, thereby realizing the positioning of the twisting disk 402. When it is necessary to adjust another swing angle of the suction piece, the third motor 605 is started. The third motor 605 drives the second driving gear 604 to rotate through the second transmission shaft 603. The second driving gear 604 drives the suction pipe 101 to swing through the gear ring 601, thereby realizing the adjustment of another swing angle of the suction piece. This enables the staff to adjust the suction position of the suction head 102 according to needs during the coal powder feeding process, so that the device can better feed the coal powder on the ground.
