Description
Technical Field
[0001] The utility model relates to the technical field of cement mixing equipment, in particular to a novel mixing device. Background Art
[0002] Cement is a key material used in construction and infrastructure construction. It is a mixture of cement clinker and gypsum. In addition to ordinary cement, there is also sulphoaluminate cement (SAC), which contains slag, a by-product generated during the blast furnace smelting of iron ore. Sulphoaluminate cement is widely used in projects such as bridges and highways due to its high early strength and good chemical corrosion resistance.
[0003] For example, the Chinese utility model patent (CN214293764U) discloses a high-efficiency discharging device for mixing building cement, which records: "By arranging a discharging control mechanism in the middle of the mixing tank, a scraping plate and a stirring blade are welded outside the rotating shaft at the top of the discharging control mechanism, and a transmission auger is arranged at the bottom of the rotating shaft. By driving the rotating shaft to rotate, the cement is stirred by the stirring blade, the cement adhered to the inner wall of the mixing tank is scraped off by the scraping plate, and an opening and closing discharging pipe is arranged at the bottom of the transmission auger. The opening and closing of the bottom cover is controlled by an electric push rod, and the transmission of the cement is controlled by the rotation of the transmission auger, which is convenient for discharging the cement inside the mixing tank, with simple and labor-saving operation and convenient use." It also records: "However, the current mixing device has low working efficiency, and it is not convenient to clean the inside of the mixing device, which is easy to generate cement substances inside. And when discharging the cement, generally, the mixing drum is rotated to pour out the cement inside the mixing drum. The mixing drum and the cement are heavy, which is not convenient to rotate the mixing drum."
[0004] To sum up, it can be seen that in the prior art, the stirring blade and the scraping plate are used to stir the cement and clean the inside of the mixing tank respectively. However, this method has the following technical problems: In the actual process, due to improper operation in the cement production process or improper handling during storage and transportation, the cement may be unevenly divided. And during the process of mixing the uneven powder materials, it takes a longer time to ensure that all the materials are fully mixed evenly, thereby increasing the time required for stirring. Therefore, this application proposes a novel mixing device to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model
[0005] Based on this, it is necessary to provide a new mixing device for the above technical problems. The driving motor can drive the first pulley to rotate, and then drive the second pulley to rotate through the belt, so that multiple scraping plates scrape the cement batching on the sieve plate, thereby improving the screening efficiency of the cement batching. The efficient screening of the cement batching can make the batching entering the mixing tank more uniform, avoiding too high cement content in some areas of the concrete, which may lead to the slurry in this part being more viscous and difficult to be evenly mixed with other parts. Therefore, in order to achieve the designed strength and consistency of the overall concrete, the mixing process requires more time to ensure that all components are fully and evenly mixed. At the same time, the efficient screening of the cement powder further improves the mixing efficiency of the cement, thereby improving the practicability of the device.
[0006] In order to solve the above technical problems, the present utility model adopts the following technical solutions:
[0007] A new mixing device is applied to slag sulphoaluminate cement.
[0008] The new mixing device specifically includes:

[0010] The disassembly mechanism includes a driving rotating rod, a driven gear, a driving component, a mixing component, and a screening component. A rotating rod is rotatably connected to the inner wall of the mixing tank, and a driven gear is fixedly connected to the outer wall of the rotating rod and located above the mixing tank.
[0011] As a preferred embodiment of the new mixing device provided by the present utility model, the driving component includes a driving motor, the driving motor is fixedly connected to the top of the mixing tank, the output end of the driving motor is fixedly connected with a driving gear, and the driving gear meshes with the outer wall of the driven gear.
[0012] As a preferred embodiment of the new mixing device provided by the present utility model, the mixing component includes stirring blades, and a plurality of stirring blades are fixedly connected to the outer wall of the rotating rod and located inside the mixing tank. A cleaning plate is fixedly connected to the side of the plurality of stirring blades away from the rotating rod.
[0013] As a preferred embodiment of the novel mixing device provided by the present utility model, the screening assembly includes a screening box. The screening box is fixedly connected to the top of the mixing tank. A rotating shaft is rotatably connected to the inner wall of the screening box. A second pulley is fixedly connected to the top end of the rotating shaft. A first pulley is fixedly connected to the top end of the rotating rod. The first pulley and the second pulley are connected by a belt drive. A sieve plate is slidably connected to the inner wall of the screening box. A plurality of scraping plates are fixedly connected to the outer wall of the rotating shaft near the bottom edge. A guiding block is fixedly connected to the inner wall of the screening box and located below the sieve plate.
[0014] As a preferred embodiment of the novel mixing device provided by the present utility model, the disassembly mechanism includes a fixed handle. The fixed handle is fixedly connected to the outer wall of the sieve plate. A jack is opened on the outer wall of the sieve plate.
[0015] As a preferred embodiment of the novel mixing device provided by the present utility model, the disassembly mechanism further includes a threaded rod. The threaded rod is threadedly connected to the inner wall of the screening box. The threaded rod is inserted into the jack. A rotating handle is fixedly connected to the end of the threaded rod away from the sieve plate.
[0016] Compared with the prior art, the present utility model has the following beneficial effects:
[0017] For the novel mixing device provided by the present utility model, the driving motor can drive the first pulley to rotate accordingly, and then drive the second pulley to rotate through the belt. Then, a plurality of scraping plates scrape the cement feed on the sieve plate, thereby improving the screening efficiency of the cement feed. The efficient screening of the cement feed can make the feed entering the interior of the mixing tank more uniform, avoiding excessive cement content in some areas of the concrete, which may lead to the slurry in this part being more viscous and difficult to be uniformly mixed with other parts. Therefore, in order to achieve the designed strength and consistency of the overall concrete, more time is required during the mixing process to ensure that all components are fully and uniformly mixed. At the same time, the efficient screening of the cement powder further improves the efficiency of cement mixing, and thus improves the practicability of the device.
[0018] For the novel mixing device provided by the present utility model, the rotating rod drives a plurality of stirring blades to rotate, which can effectively stir the cement inside the mixing tank. And the inner wall of the mixing tank can be scraped and cleaned by the cleaning plate, thereby reducing the cement residue on the inner wall of the mixing tank, reducing the cleaning difficulty of the mixing tank for the operator in the later stage, and improving the practicability of the device.
[0019] The novel mixing device provided by the present utility model enables the threaded rod to be disengaged from the jack hole by rotating the rotating handle, thereby releasing the restriction on the sieve plate. Then, by pulling the fixed handle, the sieve plate can be taken out from the screening box, which is convenient for cleaning the sieve plate to solve the problem of blockage of the sieve holes on the sieve plate. Moreover, sieve plates with different sieve hole sizes can be replaced, making the device more widely applicable. Brief Description of the Drawings

[0028] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] As described in the background art, however, in the actual process, due to improper operation in the cement production process or improper handling during storage and transportation, the cement powder may be uneven. And during the process of mixing the uneven powder, it takes a longer time to ensure that all materials are fully mixed evenly, thereby increasing the time required for mixing.
[0030] To solve this technical problem, the present utility model provides a novel mixing device, which is applied to slag sulphoaluminate cement.
[0031] Specifically, please refer to Figure 1 - Figure 2 , the novel mixing device specifically includes:
[0032] A mixing tank 1, a support frame 2 is fixedly connected to the outer wall of the mixing tank 1, a mixing mechanism 4 is arranged on the mixing tank 1, a disassembly mechanism 5 is arranged on the mixing mechanism 4, and a control valve 3 is installed on the mixing tank 1;
[0033] The disassembly mechanism 5 includes a driving rotating rod 8, a driven gear 9, a driving component, a mixing component, and a screening component. A rotating rod 8 is rotatably connected to the inner wall of the mixing tank 1, and a driven gear 9 is fixedly connected to the outer wall of the rotating rod 8 and above the mixing tank 1.
[0034] In the novel mixing device provided by the present utility model, the driving motor 6 can drive the first pulley 12 to rotate accordingly, and then drive the second pulley 15 to rotate through the belt, so that a plurality of scraping plates 16 scrape the cement material on the sieve plate 17, thereby improving the screening efficiency of the cement material. The efficient screening of the cement material can make the material entering the interior of the mixing tank 1 more uniform, avoiding too high cement content in some areas of the concrete, which may lead to the slurry in this part being more viscous and difficult to be evenly mixed with other parts. Therefore, in order to achieve the designed strength and consistency of the overall concrete, more time is required during the mixing process to ensure that all components are fully mixed evenly. At the same time, the efficient screening of the cement powder further improves the mixing efficiency of the cement, thereby improving the practicability of the device.
[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings.
[0036] Example 1:
[0037] Please refer to Figure 2 - Figure 5 , a new mixing device, which includes:
[0038] The driving component includes a driving motor 6. The driving motor 6 is fixedly connected to the top of the mixing tank 1. The output end of the driving motor 6 is fixedly connected to a driving gear 7. The driving gear 7 meshes with the outer wall of a driven gear 9. In the design of the sizes of the driving gear 7 and the driven gear 9, the diameter of the driving gear 7 can be made larger than that of the driven gear 9, so that the rotation speed of the rotating rod 8 is higher, thereby increasing the mixing rate or screening rate of the cement.
[0039] The mixing component includes mixing blades 10. A plurality of mixing blades 10 are fixedly connected to the outer wall of the rotating rod 8 and inside the mixing tank 1. A cleaning plate 11 is fixedly connected to one side of the plurality of mixing blades 10 away from the rotating rod 8. The cleaning plate 11 cleans the inner wall of the mixing tank 1, reducing the cement remaining on the inner wall of the mixing tank 1, thereby reducing the waste of raw materials.
[0040] The screening component includes a screening box 13. The screening box 13 is fixedly connected to the top of the mixing tank 1. A rotating shaft 14 is rotatably connected to the inner wall of the screening box 13. A second pulley 15 is fixedly connected to the top end of the rotating shaft 14. A first pulley 12 is fixedly connected to the top end of the rotating rod 8. The first pulley 12 and the second pulley 15 are connected by a belt drive. A sieve plate 17 is slidably connected to the inner wall of the screening box 13. The sieve plate 17 screens the cement powder, so that the powder entering the mixing tank 1 is more uniform, thereby reducing the time required for mixing the cement and improving the processing efficiency of the device. A plurality of scraping plates 16 are fixedly connected to the outer wall of the rotating shaft 14 and near the bottom edge. The scraping plates 16 can scrape the powder on the sieve plate 17, thereby improving the screening efficiency of the sieve plate 17 for the cement. A guiding block 22 is fixedly connected to the inner wall of the screening box 13 and below the sieve plate 17.
[0041] Through the above structural design, starting the driving motor 6 can drive the driving gear 7 to rotate accordingly, and then drive the rotating rod 8 to rotate through the driven gear 9, and then drive the mixing blades 10 to stir the substances in the mixing tank 1. At the same time, the cleaning plate 11 cleans the inner wall of the mixing tank 1. Meanwhile, the first pulley 12 drives the second pulley 15 to rotate through the belt, and then drives the rotating shaft 14 to rotate, and then drives the scraping plates 16 to scrape the cement powder above the sieve plate 17, so that the qualified powder quickly passes through the sieve plate 17 and enters the mixing tank 1 under the action of the guiding block 22, and then the cement is mixed.
[0042] Example 2:
[0043] The novel mixing device provided in Embodiment 1 is further optimized. Specifically, as Figure 4 shown, the disassembly mechanism 5 includes a fixed handle 18. The outer wall of the sieve plate 17 is fixedly connected with the fixed handle 18. A jack 19 is opened on the outer wall of the sieve plate 17. The jack 19 is adapted to the threaded rod 20, and the sieve plate 17 can be restricted by combining the threaded rod 20.
[0044] The disassembly mechanism 5 further includes a threaded rod 20. The inner wall of the screening box 13 is threadedly connected with the threaded rod 20. The threaded rod 20 is inserted into the jack 19. One end of the threaded rod 20 away from the sieve plate 17 is fixedly connected with a rotating handle 21. The rotating handle 21 makes it more convenient for the operator to rotate the threaded rod 20, and thus it is convenient to disassemble and replace the sieve plate 17.
[0045] Through the above structural design, rotating the rotating handle 21 will drive the threaded rod 20 to rotate, and then the threaded rod 20 gradually moves away from the jack 19. After the threaded rod 20 completely disengages from the jack 19, the fixed handle 18 can be pulled to drive the sieve plate 17 to slide inside the screening box 13 until it leaves the screening box 13. Then, the cleaned sieve plate 17 or other sieve plates with different sieve holes are inserted into the screening box 13 and slid to the appropriate position. Then, the rotating handle 21 is reversed to make the threaded rod 20 enter the jack 19 to the appropriate position, that is, the disassembly and installation of the sieve plate 17 are completed.
