[0034] Example 1
[0035] See Figure 1 to Figure 3 As shown, a conveying device for conveying bagasse to a boiler according to the present invention includes a base frame 1, a support base 2 and an impeller 3 mounted on the base frame 1, and a drive motor 4 mounted on the support base 2. And the tripod 5, the shaft body 6 rotatably connected to the support base 2. In this embodiment, the outer side of the shaft body 6 is sleeved with two rolling bearings spaced apart from each other, the two rolling bearings are mounted on the support base 2, and the tripod 5 is at a right angle Triangular, one right-angled side of the tripod 5 is installed on the support base 2, and the other right-angled side of the tripod 5 is installed on the impeller 3. Using the principle of stability of the triangle, the impeller 3 is stably positioned on the base 1 and the support The seat 2 prevents the impeller 3 from shaking during operation; the driving motor 4 drives the impeller 3 to rotate through the shaft body 6. The impeller 3 is provided with a feed hole 7 and a discharge hole 8 connected to the feed hole 7, and the bagasse outside The bagasse in the impeller 3 enters the impeller 3 through the feed hole 7, and the bagasse in the impeller 3 is transported to the outside boiler through the discharge hole 8.
[0036] In actual use, the bagasse to be transported from the outside is connected to the feeding hole 7 via a pipe. While the bagasse is input into the feeding hole 7, hot air for drying the bagasse is blown into the feeding hole 7. The hot air effectively interacts with the bagasse. Mix into a whole, reduce the humidity of the bagasse, connect the discharge hole 8 of the impeller 3 with an outside boiler, and then start the drive motor 4, and the impeller 3 extracts the bagasse from the outside so that the bagasse enters the impeller 3 through the feed hole 7. Under the action of the centrifugal force of 3, the bagasse in the impeller 3 is then injected into the boiler through the discharge hole 8. Because the bagasse particle size is different, the gravity of bagasse of different particle sizes is very different. Under the centrifugal force of the impeller 3 , So that different bagasse can be dispersed into the boiler, prevent bagasse from being piled into the boiler to burn, improve the feeding efficiency of bagasse and the combustion efficiency of bagasse, reduce the generation of nitrogen oxides, reduce the amount of flue gas discharged from the boiler, and reduce harmful The gas is generated to extend the service life of the boiler exhaust gas treatment equipment.
[0037] The impeller 3 includes a housing 9 installed on the base frame 1, a wheel 11 rotatably connected in the housing 9, a driving motor 4 drives the wheel 11 to rotate via a shaft body 6, and the feed hole 7 and the discharge hole 8 are both It is recessed from the outer surface of the housing 9, the central axis of the feed hole 7 coincides with the central axis of the wheel 11, the discharge hole 8 is located at the upper end of the housing 9, and the outlet of the discharge hole 8 is arranged upward. After the bagasse enters the impeller 3, since the center axis of the feed hole 7 coincides with the center axis of the wheel 11, under the centrifugal force of the wheel 11, the bagasse can move from the center of the wheel 11 to the edge of the wheel 11 Move the position so that the bagasse can obtain the longest possible acceleration time; when the bagasse flies from the edge of the wheel 11, ensure that the bagasse fly out at a higher speed, increase the dispersion area of bagasse of different sizes in the boiler, and assist Improve the combustion efficiency of bagasse. In addition, since the outlet of the discharging hole 8 is arranged upward, when the bagasse is sprayed from the discharging hole 8 of the impeller 3, the bagasse can be sprayed into the upper end of the boiler, so that the bagasse can start burning at the upper end of the boiler. It can continue to burn during the descent process, which further assists in improving the combustion efficiency of bagasse and prevents bagasse from being directly injected to the lower end of the boiler and cannot be fully burned.
[0038] The impeller 3 also includes a fixing seat 12, which includes a bottom plate 13 and two supporting plates 14 spaced apart from each other. The bottom plate 13 is installed on the bottom frame 1, and one end of the two supporting plates 14 is connected to the bottom plate 13. The other ends of the two supporting plates 14 are both connected to the housing 9. The bottom plate 13 and the two supporting plates 14 form a triangle, and the ends of the two supporting plates 14 away from the bottom plate 13 extend toward each other; the triangle has stability The principle of this ensures that the housing 9 is firmly connected to the base frame 1, and prevents the impeller 3 from shaking during use.
[0039] The wheel 11 includes a shaft disk 15 rotatably connected to the housing 9, a plurality of blades arranged on the shaft disk 15 and spaced apart from each other, and a cover 16 mounted on the housing 9, the shaft disk 15 or the blades, The blade and the wheel 15 of the present invention are made of special materials and have extremely high wear resistance. Compared with the traditional blade in the prior art, the service life of the blade is increased by 6-10 times, and multiple blades surround the shaft. The central axis of the disk 15 is in an annular array. Preferably, the blades are arc-shaped, and the enclosure 16 is used to cover a plurality of blades; the drive motor 4 drives the shaft disk 15 to rotate through the shaft body 6, and the central axis of the feed hole 7 is connected to the shaft disk. The central axis of 15 coincides; the feed hole 7 penetrates the enclosure 16 and reveals the gap between adjacent blades, and the gap between adjacent blades communicates with the discharge hole 8; under the centrifugal force of the wheel 11, the bagasse outside It is sucked into the gap between adjacent blades through the feed hole 7 and then sprayed into the boiler through the discharge hole 8.
[0040] The support base 2 is provided with a protective cover 17 located between the drive motor 4 and the impeller 3. The protective cover 17 is rotatably connected with a coupling 18, and both ends of the coupling 18 are respectively connected to the output shaft of the drive motor 4 and One end of the shaft body 6 and the other end of the shaft body 6 are connected to the shaft disk 15 of the impeller 3. The coupling 18 has the functions of buffering, damping vibration and improving the dynamic performance of the shaft system, so that the rotation of the output shaft of the driving motor 4 can be smoothly transmitted to the shaft body 6, and the use performance of the conveying device of the present invention is improved. By adding a protective cover 17, the protective cover 17 is used to protect the coupling 18 to prevent external objects from colliding with the coupling 18, while preventing external dust and other particles from falling into the coupling 18 and affecting the normal use of the coupling 18 .
[0041] See Figure 1 to Figure 4 As shown, the support base 2 is equipped with a bearing box 19 located between the drive motor 4 and the impeller 3. The outer side of the shaft body 6 is sleeved with two spherical roller bearings 21 spaced apart from each other. The sub-bearings 21 are all installed on the bearing box 19. By adding a spherical roller bearing 21, the wear between the shaft body 6 and the bearing housing 19 is reduced, and the service life of the shaft body 6 is prolonged; at the same time, the spherical roller bearing 21 is used to effectively compensate the output shaft of the drive motor 4 and the shaft body 6 The coaxiality error between the shaft 6 and the disc of the impeller 3 ensures the smooth operation of the conveying device of the present invention.
[0042] The bearing box 19 is equipped with a sealing cover 22 for covering the spherical roller bearing 21. The sealing cover 22 covers the spherical roller bearing 21 to prevent external dust from falling into the spherical roller bearing 21 and affecting it.
