Technical Field
[0001] The present application relates to the technical field of stirring devices, and in particular to a stirring device for preparing a concrete anti-segregation agent. Background Art
[0002] As urbanization continues to accelerate, people's requirements for commercial concrete are increasing. The deterioration of raw materials has led to an increase in uncontrollable factors in the concrete production process. It has become normal to add water and mix concrete after it is transported over long distances to the construction site. If you are not careful, it is very easy to cause accidents such as concrete segregation and pump blockage. On the other hand, excessive addition of water reducer may cause the compatibility of cement and admixtures to deteriorate, and the sensitive amount of admixtures may cause concrete segregation, affecting the construction progress and quality of concrete. Therefore, it is particularly necessary to add efficient concrete anti-segregation agent to the concrete during the production process. Existing anti-segregation agents are usually made by evenly mixing a variety of additives together, so a stirring device is required during the preparation process to fully mix the components.
[0003] The existing stirring device for preparing concrete anti-segregation agent lacks effective self-cleaning measures. When the component ratio needs to be changed in time after stirring a batch of anti-segregation agent, or when there is a long period of idle time after the production work is completed, it is necessary to manually clean the inside of the device to keep it clean. Due to the structural form of the stirring barrel, it is difficult to clean and it is time-consuming and laborious when used. Therefore, in view of the above problems, a stirring device for preparing concrete anti-segregation agent is proposed. Utility Model Content

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0026] Reference Figure 1-2 , a stirring device for preparing a concrete anti-segregation agent comprises a stirring barrel body 1, a centrally arranged rotating constraint frame 2 is fixedly arranged on the cover of the stirring barrel body 1, a hollow transmission shaft 3 extending into the stirring barrel body 1 is rotatably arranged on the rotating constraint frame 2, the hollow transmission shaft 3 comprises an outer tube 31 and an inner tube 32, a stirring frame 4 is fixedly arranged outside the outer tube 31, a driving structure 5 is fixedly arranged on the cover of the stirring barrel body 1, and a water supply structure 6 is fixedly arranged on the rotating constraint frame 2. By adopting the above technical scheme, the driving structure 5 can drive the hollow transmission shaft 3 on the rotating constraint frame 2 to rotate, so that the stirring frame 4 follows the rotation to stir and mix the materials inside. When it is necessary to clean the barrel, an external water source can enter the hollow transmission shaft 3 through the water supply structure 6 and spray out to rinse the inner wall of the stirring barrel body 1, and at the same time, the stirring frame 4 stirs the cleaning water to rotate, thereby enhancing the cleaning effect, so as to realize the self-cleaning function in the barrel, reduce the labor intensity of workers, and save time.
[0027] In particular, two symmetrically arranged stirring racks 4 are fixed outside the outer tube 31, and the angle between the vertical plane where the two stirring racks 4 are located and the vertical plane where each group of water spray outlets 34 are located is forty-five degrees. This structural form can prevent the water flow sprayed from the water spray outlets 34 from colliding with the stirring racks 4 and causing kinetic energy loss to affect the cleaning effect.
[0028] Reference Figure 2 An inner tube 32 is slidably arranged in the outer tube 31, a plurality of limiting grooves 33 are provided on the outer wall of the inner tube 32, a plurality of convex strip structures whose sizes are consistent with the limiting grooves 33 are fixedly provided on the inner wall of the outer tube 31, and a plurality of groups of water spraying ports 34 arranged equidistantly are provided on both the outer tube 31 and the inner tube 32. When the inner tube 32 is extended so that the inner tube 32 is connected with the water spraying ports 34 on the outer tube 31, water can be sprayed out from the passage formed by the water spraying ports 34 of the two. When the inner tube 32 is lowered, the water spraying ports 34 on the inner tube 32 will be covered by the outer tube 31, so that the materials in the barrel are prevented from blocking the water spraying ports 34 on the inner tube 32 during stirring.
[0029] Reference Figure 4The rotation constraint frame 2 includes a frame 21 fixedly arranged on the cover of the mixing barrel body 1, and the upper and lower cross bar parts of the frame 21 are respectively fixedly provided with an upper connecting bearing 22 and a lower connecting bearing 23 arranged in the center, and the outer tube 31 is respectively fixedly connected to the inner rings of the upper connecting bearing 22 and the lower connecting bearing 23. By adopting the above technical scheme, the upper connecting bearing 22 and the lower connecting bearing 23 can be fixedly constrained to the outer tube 31, so that it cannot be offset in any spatial position and can only rotate around its central axis.
[0030] Reference Figure 3 The driving structure 5 includes a motor fixing frame 51 fixedly arranged on the cover of the mixing barrel body 1, a driving motor 52 is fixedly installed on the motor fixing frame 51, a transmission gear 53 is fixedly connected to the output shaft end of the driving motor 52, a driven gear 54 is fixedly arranged outside the outer tube 31, and the transmission gear 53 is meshed with the driven gear 54. By adopting the above technical scheme, the driving motor 52 can drive the transmission gear 53 to rotate, thereby driving the driven gear 54 meshed with the transmission gear 53 to rotate, and finally driving the outer tube 31 to rotate, providing the necessary conditions for it to drive the internal mixing frame 4 to rotate.
[0031] Reference Figure 4 The water supply structure 6 includes a door frame 61 fixedly arranged on the frame 21, a connecting pipe 62 is fixedly installed in the middle of the door frame 61, and a plurality of circles of sealed rubber rings 63 are fixedly sleeved on the outer side of the bottom end of the connecting pipe 62. By adopting the above technical solution, the bottom end of the connecting pipe 62 can be extended into the inner pipe 32 when the inner pipe 32 is extended and is sealed and connected through the sealed rubber ring 63. At the same time, this connection method allows relative rotation between the two.
[0032] Reference Figure 5 A plurality of hinge supports 71 are fixedly provided on the outer side of the pipe mouth of the inner tube 32, and a support rod 7 is rotatably connected to the hinge support 71. A corresponding number of slots 72 are opened at the edge of the pipe mouth of the outer tube 31. When the inner tube 32 is extended so that the inner tube 32 is connected to the water spraying port 34 on the outer tube 31, the support rod 7 is flipped and inserted into the slot 72 to support and fix the inner tube 32, so that the inner tube 32 and the water spraying port 34 on the outer tube 31 can maintain a connected state. When the support rod 7 moves out of the slot 72, the inner tube 32 will drop under the action of gravity. At this time, the water spraying port 34 on the inner tube 32 will be covered by the outer tube 31, so as to prevent the material in the barrel from blocking the water spraying port 34 on the inner tube 32 during stirring.
[0033] Working principle: During stirring, the inner tube 32 is in a lowered state under the action of gravity. At this time, the water spray port 34 on the inner tube 32 will be covered by the outer tube 31 to prevent the material in the barrel from blocking the water spray port 34 on the inner tube 32 during stirring. At this time, the driving structure 5 works to drive the hollow transmission shaft 3 on the rotating constraint frame 2 to rotate as a whole, so that the stirring frame 4 follows the rotation to stir and mix the internal materials.
[0034] When it is necessary to clean the inside of the barrel, the inner tube 32 is pulled up by external force so that its mouth is tightly connected with the bottom end of the connecting tube 62. At the same time, the support rod 7 is flipped and inserted into the card slot 72 to support and fix the inner tube 32, so that the inner tube 32 and the water spray port 34 on the outer tube 31 can maintain a connected state. At this time, the external water source can enter the inner tube 32 through the connecting tube 62 and be sprayed out from the water spray port 34 on the outer tube 31 under the action of high pressure to rinse the inner wall of the mixing barrel body 1. At the same time, the mixing frame 4 stirs the cleaning water to rotate and enhance the cleaning effect. In this way, the self-cleaning function in the barrel can be realized, the labor intensity of workers can be reduced, and time can be saved.

Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
