Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5The utility model provides a technical scheme: a kind of high-efficiency preheater material scattering device, including jar body 1, the top of jar body 1 is fixedly sleeved with installation pipe 19, the top of installation pipe 19 is communicated with feed pipe 2, the inside of feed pipe 2 is movably installed with first valve 4, the outside of another end of feed pipe 2 is fixedly installed with connector 3, the inside of installation pipe 19 is provided with check valve 14, the outside of jar body 1 is fixedly installed with air pump 8, the output of air pump 8 is communicated with inclined air pipe 9, the output of air pump 8 is communicated with bottom air pipe 12, the bottom of bottom air pipe 12 is communicated with ring pipe 11, the inside of ring pipe 11 is communicated with four bottom inclined pipes 10, the inside of inclined air pipe 9 and bottom air pipe 12 is movably installed with intelligent control valve 13, the bottom of the inner chamber of jar body 1 is fixedly installed with servo motor 18, the output of servo motor 18 is drivingly connected with hollow rotating shaft 20, the outside of hollow rotating shaft 20 is fixedly installed with spiral plate 15, the outside of hollow rotating shaft 20 is fixedly penetrated and installed with stirring pipe 16, the end of stirring pipe 16 away from hollow rotating shaft 20 is fixedly installed with metal net ball 17, the outside of the top of hollow rotating shaft 20 movably sleeved with sealing cone 23, the outside of the top of hollow rotating shaft 20 is sleeved with sealing bearing 21, the top of hollow rotating shaft 20 is movably installed with rotary seal 22, the both sides of jar body 1 are communicated with material guide pipe 5, the end of material guide pipe 5 away from jar body 1 is fixedly installed with cone pipe 6, the outside of cone pipe 6 is fixedly installed with flange ring 7.
[0022] The working principle of the above technical scheme is as follows: in use, the user connects the discharge port to the preheater input air pipe through the flange ring 7, and connects the connector 3 to the raw material storage output mechanism. When the raw material is input into the inside of the feed pipe 2 and the installation pipe 19, the air pump 8 and the servo motor 18 are started, and the intelligent control valves 13 of the inclined air pipe 9 and the bottom air pipe 12 are opened. At this time, the powder material enters the opposite side of the inclined air pipe 9 and the hollow rotating shaft 20 through the installation pipe 19 and the check valve 14. The airflow output by the inclined air pipe 9 carries the powder material into the inside of the hollow rotating shaft 20, and the airflow is guided into the inside of the metal net ball 17 through the stirring pipe 16. At this time, the airflow and the powder material are mixed in the mesh of the metal net ball 17, so that the powder material is converted into a dust state, and the hollow rotating shaft 20 is driven to rotate by the servo motor 18, so that the spiral plate 15 and the stirring pipe 16 rotate, so that the raw material dust is uniformly mixed. At this time, the bottom is subjected to the output airflow of the bottom air pipe 12, and the airflow is guided into the inside of the jar body 1 through the ring pipe 11 and the bottom inclined pipe 10. At this time, the dust is guided out of the preheater air pipe through the material guide pipe 5 and the cone pipe 6, and enters the heat exchange preheating. The overall scheme makes the raw material dust evenly distributed, improves the mixing efficiency, and facilitates efficient and uniform material scattering.
[0023] In another embodiment, as Figures 1-4As shown, the inclined air pipe 9 is fixed through the tank body 1 and the installation pipe 19 and is communicated to the inside of the installation pipe 19, one end of the inclined air pipe 9 inside the installation pipe 19 is distributed in an inclined downward direction, and the one-way valve 14 is located on the opposite side of the first valve 4 and the inclined air pipe 9.
[0024] The inclined air pipe 9 outputs the airflow downward and synchronously with the direction of the raw material added through the feeding pipe 2, blows the raw material downward, facilitates the stable output of the material, and promotes the raw material to move downward through the one-way downward of the one-way valve 14, avoids the airflow from carrying the raw material to move upward in the opposite direction, and improves the efficiency of flow guide. If it is necessary to adjust the dispersion of the raw material and the airflow, it is only necessary to control the flow of the inclined air pipe 9 and the bottom air pipe 12 through the intelligent control valve 13 to control the proportion of the falling raw material and the airflow, thereby facilitating the increase of the control effect.
[0025] In another embodiment, as shown in Figures 1-4 The four bottom inclined pipes 10 are circumferentially fixed through the tank body 1 and are communicated to the inside of the tank body 1, and the four bottom inclined pipes 10 are all distributed in an inclined manner at the bottom of the inner cavity of the tank body 1.
[0026] The bottom inclined pipe 10 uniformly guides the airflow input by the ring pipe 11 to the inside of the tank body 1, facilitates the flow guide of the airflow output by the bottom air pipe 12, increases the convenience of the output at the bottom, reduces the deposition of the raw material dust, and facilitates the increase of the airflow output effect.
[0027] In another embodiment, as shown in Figure 3 and Figure 4 The outer side of the spiral plate 15 is in sliding contact with the inner wall of the tank body 1, and the specification size of the spiral plate 15 is adapted to the specification size of the tank body 1.
[0028] When the hollow rotating shaft 20 rotates, the spiral plate 15 and the stirring pipe 16 are driven to rotate, the spiral plate 15 is disturbed to the powder entering the inside of the tank body 1, and the output of the stirring pipe 16 is cooperated to make the powder and the airflow uniformly mixed, so that the raw material is more efficiently distributed, and the airflow output of the inclined air pipe 9 and the bottom air pipe 12, so that the powder is more uniformly distributed, the uniformity of the bulk material is increased, the deposition of the raw material is reduced, and the efficiency of the raw material spreading is increased.
[0029] In another embodiment, as shown in Figure 3 and Figure 4 The stirring pipe 16 is spirally and uniformly distributed on the outer side of the hollow rotating shaft 20, and the two ends of the stirring pipe 16 are respectively communicated to the inside of the hollow rotating shaft 20 and the metal mesh ball 17.
[0030] The spiral action of the stirring pipe 16 facilitates the uniform output of the airflow and the raw material, and cooperates with the rotation of the spiral plate 15 to make the raw material flow guide stable and have the stirring effect, thereby facilitating the uniform mixing.
[0031] In another embodiment, as shown in Figures 3-5 The top of the sealing cone 23 is fixedly installed at the bottom of the mounting pipe 19, the movable installation of the rotary seal 22 is installed inside the mounting pipe 19, and the sealing bearing 21 is movably sleeved inside the mounting pipe 19.
[0032] The sealing cone 23 and the rotary seal 22 seal both ends of the sealing bearing 21 and facilitate the sealing of the connection between the hollow rotating shaft 20 and the mounting pipe 19, increase the structural sealing, and ensure the stability of the rotation of the hollow rotating shaft 20, facilitating the rotation of the mounting pipe 19.
[0033] In another embodiment, as shown in Figures 1-4 The material guide pipe 5 is fixedly sleeved inside the tank body 1, and the inner walls of the material guide pipe 5 and the taper pipe 6 are made of ceramic material.
[0034] The ceramic material of the material guide pipe 5 and the taper pipe 6 facilitates the reduction of friction on the raw material and the rapid passage of airflow, increases the wear resistance, reduces dust accumulation, avoids blockage in cooperation with the airflow, and improves the efficiency of the output raw material.
