Description

Technical Field

[0001] The invention relates to the technical field of hammer-type dispersing machines, in particular to a spiral-propelled hammer-type dispersing machine. Background Art

[0002] The particle size of the hammer disperser's feed is relatively fine, and the moisture content of the material is also different from the dryness of the material crushed in other industries. With a certain moisture content, the material is easy to stick together into a mass, causing material accumulation, and even causing the hammer head to stick to or clamp the material. In order to avoid this phenomenon, a hot air channel is usually set inside the disperser for heating and drying, that is, the hot air enters and exits from the top of the disperser.

[0003] At present, the existing hammer type dispersers usually use heat source air to directly heat and dry the materials, and the materials are mainly concentrated in the mixing chamber by their own gravity. During the feeding process, the speed of the materials falling by their own gravity is difficult to control and is relatively fast. The faster falling speed easily causes the contact time with the heat source air to be shorter. The shorter contact time easily causes insufficient drying, which is not conducive to the drying of moisture in the gypsum material. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1-2 As shown, a spiral propulsion hammer type scattering machine includes:

[0041] The machine body 1 is provided with a mixing chamber 2 at the center of the inner cavity of the machine body 1 for mixing materials, a feeding port 9 is provided at the top of the machine body 1, and the feeding port 9 is connected to the mixing chamber 2; a discharging port 10 is provided at the bottom of the machine body 1, and the discharging port 10 is connected to the mixing chamber 2; a side wall of the machine body 1 is provided with an exhaust passage 3 connected to the mixing chamber 2; a roller 4 is rotatably connected in the mixing chamber 2; a plurality of hammer pieces 5 are provided, and a plurality of threaded grooves 12 for installing the hammer pieces 5 are provided on the outer surface of the roller 4 at positions distributed along the hammer pieces 5; a hot air piece 6 is provided on one side of the machine body 1, and the hot air piece 6 is a conventional hot air component with the effect of exporting hot air, and the air outlet end of the hot air piece 6 is connected to the rotating end of the roller 4.

[0042] Among them, the material is introduced into the mixing chamber 2 through the feed port 9, and after drying, it is discharged through the discharge port 10. During drying, the hot air component 6 introduces the external hot air into the mixing chamber 2 through the hammer head component 5, and the hammer head component 5 can gradually spray hot gas during rotation. The drying area is large, but during the drying process, the material enters from the feed port 9 to the discharge port 10, and the material slides down too fast, resulting in excessive drying time. In order to extend the drying time of the material, the material's travel trajectory in the mixing chamber 2 is adjusted.

[0043] Specifically, a plurality of hammer pieces 5 are arranged in a spiral manner along the length direction of the outer circumference of the roller 4 for spiral feeding and breaking up the material. An air guide cavity 7 is provided in the inner cavity of the roller 4, and the air guide cavity 7 is communicated with the air outlet end of the hot air piece 6. A plurality of microporous air channels 8 are provided on the outer wall of the roller 4, and the microporous air channels 8 are communicated with the air guide cavity 7; so that the hot gas generated by the hot air piece 6 is introduced into the mixing chamber 2 through the roller 4 and discharged from the exhaust channel 3; under the rotation of the roller 4, the spirally distributed hammer pieces 5 are driven to feed the material step by step, so as to prolong the heating time of the material in the mixing chamber 2.

[0044] The device arranges the hammer head with a breaking effect into a spiral shape, which is similar to the structure of an auger. The material entering from the feed port is hammered by the hammer head and the material is gradually advanced in a spiral manner. In the process of the material moving forward, the material is dried by the drying effect of the hot air part 6. The spiral advancement of the material is beneficial to increasing the path of the material, thereby increasing the drying time of the whole material in the mixing chamber, and further facilitating the removal of moisture in the material.

[0045] When the hammer material is dried, the material is introduced into the mixing chamber 2 from the feed port 9. The material entering the mixing chamber 2 drives the roller 4 to rotate under the action of an external driving force. Since the hammer head 5 is connected and fixed to the roller 4, the hammer head 5 moves synchronously with the roller 4 under the rotation of the roller 4. The moving hammer head 5 has the dual functions of hammering and spiral feeding. When feeding, the hot air part 6 introduces hot air into the air guide cavity 7 in the roller 4. The introduced hot air flows into the microporous air channel 8 along the air guide cavity 7, and is introduced into the mixing chamber 2 through the microporous air channel 8, and then the introduced hot air is used to dry the material.

[0046] Further, such as Figure 1-2 As shown, both ends of the roller 4 are connected with a rotor 11 which is rotatably connected to the mixing chamber 2; the rotor 11 close to one end of the hot air member 6 is a hollow structure, one end of the rotor 11 is rotatably connected to the hot air member 6 through a bearing, and the other end is rotatably connected to the roller 4 and extends into the air guide chamber 7; the rotor 11 away from one end of the hot air member 6 is a solid structure, one end of the rotor 11 is rotatably connected to the roller 4, and the other end is connected to the power output end of the external driving source, and the rotation of the roller 4 is mainly driven by two of the rotors 11.

[0047] Among them, during the drying process, since hot air has a tendency to flow upward, in order to better utilize the flow characteristics of hot air.

[0048] Specifically, Figure 1 As shown, the mixing chamber 2 is tilted, the exhaust passage 3 is arranged at the higher end of the mixing chamber 2, and a feed port 9 is opened on the top of the body 1 at the higher end of the mixing chamber 2, and the feed port 9 is connected to the mixing chamber 2.

[0049] Since the hammer head 5 is in direct contact with the material during the hammering process, and the gypsum material with moisture is easily adhered to the hammer head 5, in order to avoid the adhesion of the hammer head 5 and to further increase the flow range of the hot air, the drying effect is improved.

[0050] Specifically, Figure 2-3 As shown, an air guide column 13 is provided at the center of the inner cavity of the thread groove 12. The air guide column 13 is a hollow structure with two ends opened. One end of the air guide column 13 is connected to the air guide cavity 7, and the other end is connected to the hammer head 5 by thread.

[0051] Among them, further, Figure 2-3 As shown, the hammer head member 5 includes a hammer head 51 and a hammer handle 52 , which are integrally formed by injection molding. Interconnected air guide holes 14 are provided between the hammer head 51 and the hammer handle 52 , and the air guide holes 14 are connected to the air guide columns 13 .

[0052] When the hot gas enters the air guide cavity 7, a part of the gas flows out from the air guide hole 14, and the other part of the gas flows out from the air guide column 13. The hot gas passing through the air guide column 13 flows into the hammer head 51 through the air guide hole 14 in the hammer handle 52. The introduced hot air can heat the hammer head 51 and quickly dehydrate the adhered material so that the adhered material becomes dry and falls off. In order to further accelerate the falling off of the adhered material, an air outlet micropore 15 connected to the air guide hole 14 is opened on the side wall of the hammer head 51. The exhaust gas from the air outlet micropore 15 impacts the adhered material to make the adhered material fall off. The impacting gas is hot air, which also has a drying effect.

[0053] Further, such as Figure 2-3 As shown, the outlet end of the air outlet micropore 15 is inclined to the outer surface of the hammer head 51, and the inclination direction of the air outlet end of the air outlet micropore 15 is toward the rotating roller 4. There is a certain angle between the air outlet micropore 15 in the inclined direction and the material. When the hammer head 51 beats the material, the gypsum material is not easy to enter the air outlet micropore 15, and blockage may occur in time. Under the action of hot air impact, it is also more conducive to unblocking.

[0054] Furthermore, an external thread is provided on the outer side of the column body of the air guide column 13, and an internal thread matching the external thread is provided on the inner cavity side wall of the air guide hole 14. On the one hand, the threaded connection method facilitates the disassembly and installation between the hammer handle 52 and the air guide column 13, and the firmness can also be guaranteed. On the other hand, it can also improve the sealing effect of the connection and improve the air tightness.

[0055] Although the multiple hammer head members 5 are arranged in a spiral structure, the size of the hammer head 51 is larger than the size of the hammer handle 52, and there is a certain installation gap between two adjacent hammer handles 52. Due to the existence of the installation gap, a small amount of gypsum material falling on the roller 4 will continuously slide along the gap, which is not conducive to the gradual transportation of the material. In order to avoid such a phenomenon, a blocking member 16 is connected between the two connected hammer handles 52, and a structure similar to an auger is formed between the multiple blocking members 16 to block the material falling on the roller 4.

[0056] Specifically, Figure 3-4 As shown, the blocking member 16 includes a blocking piece 161 and two connecting half rings 162, and the two connecting half rings 162 are respectively fixedly connected to the two ends of the blocking piece 161. The blocking member 16 includes a blocking piece 161 and two connecting half rings 162, and the two connecting half rings 162 are respectively fixedly connected to the two ends of the blocking piece 161. Both ends of the openings of the two connecting half rings 162 are provided with fixing ears 163, and the two fixing ears 163 are provided with mounting holes; the two fixing ears 163 in two adjacent blocking members 16 are fixed by fixing bolts to form a circular ring that cooperates with the hammer handle 52.

[0057] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
