Description

Technical Field

[0001] The invention relates to the technical field of cement material processing, and in particular to a processing device for producing solid waste gelling materials for cement. Background Art

[0002] The gel material formed by mixing various solid wastes such as blast furnace slag, steel slag, desulfurized gypsum, fly ash and the like with an activator can effectively replace the traditional cement-based concrete cementitious materials. In the actual production and processing of solid waste cementitious materials, iron tailings, blast furnace slag, fly ash, desulfurized ash and carbide slag are ground respectively, and the raw materials are fully mixed with the activator after reaching the particle gradation. During the mixing process, the two are usually directly sent to the mixing tank, and then the mixing operation is carried out by using the stirring structure inside the mixing tank. Whether the materials can be fully mixed and uniform depends mainly on the setting of the stirring structure. If the stirring structure is reasonably designed, the raw materials can be mixed uniformly within a certain period of time. However, since the two are piled up together in a large area in the initial state, the stirring structure needs to spend a long enough time to ensure uniform mixing. Moreover, since the position of the existing stirring structure in the tank body is fixed, the stirring area of ​​the stirring structure for the material is also fixed and limited, which will also affect the mixing quality of the raw materials. If the two raw materials can be mixed in advance when feeding, then the stirring time will undoubtedly be shortened, and the design of the stirring structure is more reasonable, which can further ensure the mixing quality. Based on this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0034] This embodiment provides a processing device for producing solid waste cementitious materials for cement. Figures 1 to 9As shown, it includes a stirring tank 1, the top of which is connected to a first feeding pipe 2 and a second feeding pipe 3, the bottom of which is located on the ground through a plurality of supporting legs 6, and a discharging pipe 5 is also connected to the bottom, wherein the first feeding pipe 2 is used for pouring in solid waste materials, and the second feeding pipe 3 is used for pouring in activating agents, and a rotating shaft 9 is rotatably installed inside the stirring tank 1 along its axial direction, the bottom of the rotating shaft 9 is rotatably installed at the center of the bottom of the stirring tank 1, and the top extends to the outside of the stirring tank 1 and is connected to a motor 4 installed on the top of the stirring tank 1, and a plurality of first stirring paddles 11 are distributed on the outside of the rotating shaft 9 along its axial direction, when the solid waste materials and the activating agents are put into the stirring tank 1 according to a proportion, the motor 4 drives the rotating shaft 9 to rotate, and the solid waste materials and the activating agents are fully and evenly mixed by the first stirring paddle 11, and then poured out from the discharging pipe 5 after being evenly mixed.

[0035] The traditional solution is to pour the solid waste and the activator into the mixing tank 1 uniformly, and then mix the two through the mixing structure. Whether the two materials can be fully mixed depends on the design of the mixing structure. The solution proposed by the present invention is to set a mixing disk 8 at the position close to the feed inside the mixing tank 1. The mixing disk 8 is fixed on the circumferential surface of the rotating shaft 9. The solid waste and the activator fall into the mixing disk 8 through the first feeding pipe 2 and the second feeding pipe 3 respectively. The mixing disk 8 is in a rotating state under the action of the motor 4. Therefore, the solid waste and the activator fall into the rotating mixing disk 8 and are spread out in a ring shape, and the two are alternately layered. Spread flatly, so that the contact area between the solid waste and the activator can be increased, and the two can be pre-mixed before being stirred. After the mixing disk 8 rotates at least one circle, the two material receiving plates 19 in the mixing disk 8 can be turned over, so that the pre-mixed materials fall into the mixing tank 1 for further stirring and mixing, and then the two material receiving plates 19 are reset, and the solid waste and the activator fall onto the mixing disk 8 again, and this cycle is repeated until the solid waste and the activator are all added to the mixing tank 1. Since the solid waste and the activator have been pre-mixed before being formally stirred, the time can be greatly shortened by stirring and mixing evenly, and the design requirements of the stirring structure are not so high.

[0036] Specifically, the mixing plate 8 in this embodiment includes an outer ring body 17 arranged concentrically with the rotating shaft 9, and a transverse plate 18 is integrally formed on the top of the outer ring body 17, and the transverse plate 18 passes through the center of the outer ring body 17, and a through hole 22 matching the diameter of the rotating shaft 9 is opened at the center thereof, and the transverse plate 18 is fixedly sleeved on the rotating shaft 9 and rotates synchronously therewith, and two material holding plates 19 are symmetrically installed on the inner side of the outer ring body 17 on both sides of the transverse plate 18, and the two material holding plates 19 are fixedly connected to the hinge shaft on one side facing each other. 23, each material receiving plate 19 is rotationally connected to the outer ring body 17 through a hinge shaft 23, and two cylinders 20 are hinged at the bottom of one of the material receiving plates 19, and the piston rod of each cylinder 20 is hingedly connected to another material receiving plate 19, and the two material receiving plates 19 are driven to rotate relative to the outer ring body 17 through the synchronous action of the two cylinders 20, so that the two material receiving plates 19 move synchronously toward or away from each other, and when the two material receiving plates 19 rotate toward each other to an inclined state, the material can slide into the mixing tank 1. Of course, in order to avoid the two material receiving plates 19 from interfering with the rotating shaft 9 when rotating toward each other, the present invention chooses to open an avoidance groove 21 at the lower end of the two material receiving plates 19, and the length of the avoidance groove 21 can be set to be the same as the radius of the material receiving plate 19, so that even if the two material receiving plates 19 are rotated to a vertical state, they will not interfere with the rotating shaft 9.

[0037] In the above scheme, the mixing disk 8 can be directly in contact with the inner wall of the stirring tank 1, so as to prevent the material from falling from the area between the mixing disk 8 and the inner wall of the stirring tank 1 and being unable to be premixed. Of course, the bracket 7 can also be fixed on the inner wall of the stirring tank 1 corresponding to the periphery of the mixing disk 8. The upper end face of the bracket 7 is an inclined structure, and the inclined surface of the upper end of the bracket 7 directly extends to the edge of the material holding plate 19. Through the inclined upper end face of the bracket 7, not only can the material be prevented from falling directly to the bottom of the stirring tank 1, but also the material can be guided to the material holding plate 19, and the outer ring body 17 is embedded in the inside of the bracket 7 and slidably connected thereto.

[0038] In order to further improve the stirring and mixing effect of the material inside the stirring tank 1, the present invention makes full use of the movement of the material holding plate 19 to make the stirring structure inside the stirring tank 1 reciprocate in the axial direction, thereby increasing the contact area between the stirring structure and the material, thereby ensuring the mixing effect. Specifically, the present invention has a sleeve 10 slidingly sleeved on the outside of the rotating shaft 9, and several first stirring paddles 11 are evenly distributed on the sleeve 10. The lower end surfaces of the two material receiving plates 19 are hingedly connected with a connecting rod 12, and the other end of the connecting rod 12 is hingedly connected to the circumferential surface of the sleeve 10 near its bottom. When the two material receiving plates 19 rotate toward each other with the hinge shaft 23 as the center, they will act on the connecting rod 12, so that the connecting rod 12 drives the sleeve 10 to slide downward in the vertical direction on the rotating shaft 9. It should be noted that since the sleeve 10 always rotates synchronously with the rotating shaft 9, and it is also required to be able to slide axially relative to the rotating shaft 9, the present invention chooses to fix and connect the limiting ribs 16 on the circumferential surface of the rotating shaft 9 along its axial direction, and the circumferential surface inside the sleeve 10 is formed with a rib groove compatible with it. The two material holding plates 19 rotate toward each other periodically, thereby driving the sleeve 10 to reciprocate relative to the rotating shaft 9, so that the first stirring paddles 11 reciprocate in the vertical direction, so that the first stirring paddles 11 stir and mix the materials in different areas inside the stirring tank 1.

[0039] In the initial state, the bottom of the sleeve 10 is at a long distance from the bottom of the mixing tank 1. When the two material containing plates 19 rotate toward each other to the maximum angle, the bottom of the sleeve 10 just moves to the bottom of the mixing tank 1. However, when the material just falls into the bottom of the mixing tank 1, the blank area here cannot be stirred immediately. In order to avoid this phenomenon, the present invention provides a fourth stirring paddle 15 on the circumferential surface of the bottom end of the rotating shaft 9. The fourth stirring paddle 15 is fitted with the bottom of the mixing tank 1. When the material just enters the interior of the mixing tank 1 and is small, the fourth stirring paddle 15 is mainly used for stirring and mixing.

[0040] In the present invention, not only can the action of the two material containing plates 19 be utilized to drive the first stirring paddle 11 to move in the vertical direction, but also the swing of the connecting rod 12 can be used. By installing a plurality of second stirring paddles 13 on the plate surface of the connecting rod 12 facing the inner wall of the stirring tank 1, when the sleeve 10 moves in the vertical direction relative to the rotating shaft 9, the two connecting rods 12 can swing relative to the sleeve 10, and the plurality of second stirring paddles 13 on the connecting rod 12 can disturb the material in the axial and radial directions, making the movement of the material more irregular. It should be noted that the first stirring paddle 11 and the second stirring paddle 13 in the present invention are twisted at a certain angle along the extension direction of the paddles, so that when the two stir the material, not only can the material be disturbed in the radial direction, but also in the axial direction.

[0041] Furthermore, the present invention also has multiple groups of third stirring paddles 14 symmetrically arranged on both sides of each connecting rod 12 along its length direction, and the two third stirring paddles 14 in each group are arranged perpendicular to the length direction of the connecting rod 12. When the connecting rod 12 swings relative to the sleeve 10, the third stirring paddles 14 can also directly act on the material, so that the material flows from the center of the stirring tank 1 to the outside, or the material flows from the outside toward the center of the stirring tank 1, so that the material moves irregularly in multiple directions. In addition, it can be imagined that since the connecting rod 12 can swing relative to the sleeve 10, and there are several third stirring paddles 14 distributed on the connecting rod 12, it is necessary to control the installation position of the third stirring paddle 14 on the connecting rod 12 and the distance between two adjacent third stirring paddles 14 to ensure that the third stirring paddle 14 will not interfere with the first stirring paddle 11 during the relative swinging of the connecting rod 12 and the sleeve 10.

[0042] The solid waste falls from the first feeding pipe 2 onto the mixing plate 8, and the activator falls onto the mixing plate 8 via the second feeding pipe 3. Since the solid waste materials and the activator constituting the gel material are different in composition, the feeding amounts of the first feeding pipe 2 and the second feeding pipe 3 are controlled according to the size of the components, so as to ensure that the solid waste materials and the activator are fed synchronously at the same time as much as possible. During the feeding process, the rotating mixing disk 8 premixes the solid waste material and the activator. When the premixed material on the mixing disk 8 enters the bottom of the stirring tank 1, since the first feeding pipe 2 and the second feeding pipe 3 are still continuously feeding, the two receiving plates 19 rotate toward each other. The materials entering through the first feeding pipe 2 and the second feeding pipe 3 directly fall into the stirring tank 1 due to the loss of the bearing function of the receiving plates 19, so this part of the materials cannot be mixed. Therefore, it is necessary to temporarily block the first feeding pipe 2 and the second feeding pipe 3 during the process of the two receiving plates 19 rotating and unloading. When the two receiving plates 19 have finished unloading and reset, the materials can fall smoothly onto the mixing disk 8 again. In order to achieve this effect, the present invention is rotatably installed with a turntable 24 on the top of the inner side of the stirring tank 1, and the inner side of the turntable 24 is fixedly connected with An annular rack 28, the top of the mixing tank 1 is located on the inner side of the annular rack 28 and three second gears 27 meshing with the annular rack 28 are distributed in an annular manner, and a first gear 26 meshing with the outside of the second gear 27 is fixedly sleeved on the circumferential surface of the rotating shaft 9. By setting the diameter ratio of the first gear 26, the second gear 27 and the annular rack 28, the turntable 24 rotates 60° for every 360° rotation of the rotating shaft 9, and four arc-shaped feeding troughs 25 are evenly distributed in an annular manner on the turntable 24. The starting end of each feeding trough 25 is consistent with the diameter of the first feeding pipe 2 or the second feeding pipe 3, and the end is integrally connected with a semicircular baffle 29 consistent with the diameter of the first feeding pipe 2 or the second feeding pipe 3. The central angle corresponding to each feeding trough 25 is 60°, and the central angle corresponding to each semicircular baffle 29 and the starting end of the next feeding trough 25 is 30°. In the initial state, the first feed pipe 2 and the second feed pipe 3 are respectively located at the starting ends of the corresponding drop troughs 25. When the rotating shaft 9 rotates 360°, the turntable 24 rotates 60°, and the solid waste materials and the activating agent fall onto the mixing disk 8 alternately, while the first feed pipe 2 and the second feed pipe 3 are blocked by the semicircular baffles 29 respectively. At this time, the two cylinders 20 drive the material receiving plates 19 to rotate toward each other, so that the materials on the mixing disk 8 fall into the bottom of the mixing tank 1. When the two material receiving plates 19 are completely reset, the turntable 24 continues to rotate until it rotates 30°, and the first feed pipe 2 and the second feed pipe 3 are connected to the next drop trough 25 again, and the material is discharged again, and this cycle is repeated.

[0043] When all the solid waste materials and activating agents fall into the mixing tank 1, the two material holding plates 19 can be driven by the cylinder 20 to rotate toward each other to a certain angle, so that the sleeve 10 slides down to the bottom of the rotating shaft 9, and all the first stirring paddles 11, the second stirring paddles 13 and the third stirring paddles 14 are stirred at a relatively fixed position for a set time. In addition, the present invention does not limit the rotation angle of the two material holding plates 19. When the two material holding plates 19 are fully rotated to a vertical state, the sleeve 10 can slide to the bottom relative to the rotating shaft 9, or the two material holding plates 19 can be rotated to a certain angle to drive the sleeve 10 to slide to the bottom relative to the rotating shaft 9, as long as the material on the material holding plates 19 can slide smoothly to the bottom of the mixing tank 1.
