[0002] In the construction process of various backfill projects, problems such as unstable compaction of backfill soil and difficulty in backfilling basements are often encountered. Therefore, a process of backfilling using cement soil containing industrial waste slag has appeared on the market. Industrial waste slag cement soil mainly uses various types of industrial waste slag (such as crushed construction waste, gravel with a large amount of mud, stone powder, etc.), cement, water, and curing agent as main raw materials. The mix ratio design is adjusted through experiments according to performance requirements, which can effectively utilize waste, save construction costs, save construction time, etc. However, when mixing industrial waste slag cement soil, since it contains some different types of waste slag, it is easy for the waste slag to be incompletely crushed, resulting in the quality of the backfill soil after mixing using existing mixing equipment not meeting the standards, which in turn affects the structural strength and other properties of the backfill soil and reduces the quality of the backfill. Utility Model Content

[0003] The utility model aims to provide an industrial waste slag cement soil premixing device, which can solve the technical problem that the existing waste slag backfill soil has uneven waste slag particles and thus affects the backfill quality. The waste slag raw materials are further crushed and filtered during stirring to ensure that the size and uniformity of the waste slag particles during mixing meet the requirements, thereby ensuring the performance of the waste slag backfill soil after solidification and ensuring the quality of the backfill.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions:

The feed plate 4 is tilted and located below the bottom of the feed hopper 3, so that the various components in the feed hopper 3 fall through the feed plate 4 at the bottom and enter the mixing tank 2. A partition 5 is welded or bolted in the feed hopper 3. The partition 5 divides the interior of the feed hopper 3 into a waste slag feeding area 6 and a general feeding area 7. The waste slag feeding area 6 is only used for feeding waste slag, and the general feeding area 7 is used for feeding cement, curing agent and other components. A crushing roller 8 is symmetrically connected to the feed zone 6 through a bearing for rotation. The crushing roller 8 is driven to rotate by an existing motor structure. Crushing teeth are arranged on the crushing roller 8, so that the waste slag entering from the waste slag feed zone 6 is further crushed before mixing, thereby preventing unevenly crushed large particles of waste slag from entering the mixing tank 2. A discharge port 9 is arranged on the side wall of the waste slag feed zone 6. The discharge port 9 penetrates the side wall of the waste slag feed zone 6. A filter screen 10 arranged obliquely is movably connected to the discharge port 9. The filter screen 10 is located on the crushing roller 8. 9, so that the waste residue after crushing needs to be screened by the filter screen 10 before entering the mixing tank 2, ensuring that the waste residue with the required size and uniformity can be mixed and stirred, thereby ensuring the performance of the mixed waste residue backfill soil, and further ensuring the quality of the backfill, the filter screen 10 is detachably connected to the discharge port 9, so that the filter screens 10 of different sizes can be replaced according to the performance requirements, thereby achieving the mixing and mixing requirements of waste residue backfill soil with different performances, and the upper edge of the outer wall of the feed hopper 3 is vertically slidably connected with a lifting frame 11, and the lifting frame 11 is rotatably connected with a circulating hopper 12 used in conjunction with the discharge port 9 through a pin shaft or a hinge. Such a structure allows large particles of waste residue blocked by the filter screen 10 to pass through the discharge port 9 and enter the circulating hopper 12, and the circulating hopper 12 is driven to rise by the lifting frame 11 and then rotated and tilted, and the large particles of waste residue are poured into the feed hopper 3 again for crushing, thereby ensuring the accuracy of the weight of the waste residue components added, ensuring the accuracy of the proportion of each component of the waste residue backfill soil, and ensuring the quality and accuracy of the mixing and stirring.

[0024] Preferably, a limit plate 13 is welded or bolted on the side wall opposite to the discharge port 9 in the waste slag feeding area 6, and the limit plate 13 is movably connected to the end of the filter screen 10. Specifically, a frame is arranged on the outside of the filter screen 10, and the end of the frame is plugged into the limit plate 13. Such a structure can be used to plug and fix one end of the filter screen 10 with the limit plate 13 after the filter screen 10 is installed from the discharge port 9, thereby achieving effective support for the filter screen 10, further ensuring the stability of the structure of the filter screen 10, and ensuring the filtering effect.

[0025] Preferably, see Attachment Figure 6A limiting groove 14 is provided at the end of the filter 10, and the limiting groove 14 is recessed inwardly from the end of the filter frame 10. The limiting plate 13 is movably plugged into the limiting groove 14, and a suction plate 15 is provided in the limiting groove 14 that is magnetically attracted to the limiting plate 13. After the limiting groove 14 on the frame is plugged and fixed with the limiting plate 13, the suction plate 15 is magnetically attracted to the limiting plate 13 to further fix the filter 10, avoid tilting and shaking of the filter 10 during the filtering process, and further ensure the effect of filtering waste residue.

[0026] Preferably, a guide frame 16 is symmetrically welded or bolted on the outer wall of the feed hopper 3, and both ends of the lifting frame 11 are slidably connected to the guide frame 16. The setting of the guide frame 16 makes the lifting frame 11 more stable when sliding up and down. The lifting frame 11 is rotatably connected with a telescopic rod 17 through a pin or a hinge, which can be specifically adopted by a cylinder or an oil cylinder. The end of the telescopic rod 17 is rotatably connected to the bottom of the circulation hopper 12 through a pin or a hinge. Such a structure can drive the circulation hopper 12 to rotate around the rotating position relative to the lifting frame 11 when the telescopic rod 17 is extended or retracted, thereby facilitating the pouring of large-particle impurities in the circulation hopper 12 into the feed hopper 3 again, thereby realizing automatic circulation feeding of waste slag, further simplifying the feeding steps, and ensuring the smoothness and convenience of the waste slag circulation feeding.

[0027] Preferably, see Attachment Figure 4 The top of the circulation hopper 12 and the side facing the feed hopper 3 are both provided with openings 18, and the height of the top of the guide frame 16 is higher than the feed hopper 3. Such a structure enables the lifting frame 11 to drive the circulation hopper 12 to rise to a height higher than the top of the feed hopper 3, and then pour out the waste slag therein by rotating toward the feed hopper 3, so that the waste slag passes through the opening 18 and enters the waste slag feeding area 6 from the top of the feed hopper 3, thereby realizing automatic circulation feeding of large-particle waste slag, avoiding the falling and waste of waste slag, and ensuring the accuracy of the added weight of waste slag.

The guide rod 20 passes through the slide block 21 on the other side and is slidably connected with it. Such a structure utilizes the rotation of the screw 19 to realize the up and down sliding drive of the lifting frame 11 along the guide rod 20, so that the sliding structure of the lifting frame 11 and the circulating hopper 12 thereon is more stable, and the operation of waste slag circulating feeding is more efficient and accurate.

[0029] Working principle: The structure of the utility model is provided with a partition plate 5 in the feed hopper 3, which divides the interior of the feed hopper 3 into a waste slag feeding area 6 and a common feeding area 7. The waste slag feeding area 6 is symmetrically provided with a crushing roller 8 for rotation. Such a structure allows the waste slag raw materials to be further crushed by the crushing roller 8 before mixing. The crushed waste slag is filtered by the filter net 10 below, so that the waste slag with a size and uniformity that meets the use requirements passes through the feed plate 4 below the feed hopper 3 and enters the mixing tank 2 for mixing, thereby reducing the influence of incompletely crushed large particles of waste slag on the overall quality of the waste slag backfill soil, ensuring the performance of the waste slag backfill soil and the quality of the backfill; in the waste slag feeding A discharge port 9 is arranged on the side wall of the zone 6, a filter screen 10 is movably connected to the discharge port 9, a lifting frame 11 is vertically slidably connected to the outer wall of the feed hopper 3, and a circulation hopper 12 used in conjunction with the discharge port 9 is rotatably arranged on the lifting frame 11. Such a structure enables the large particles of waste slag filtered out by the filter screen 10 to pass through the discharge port 9 and enter the circulation hopper 12. After the circulation hopper 12 rises, the large particles of waste slag therein are poured into the feed hopper 3 again, so that the waste slag can be crushed and utilized again, and the loss of the amount of waste slag can be avoided, thereby ensuring the accuracy of the weight of the added waste slag, ensuring the accuracy of the proportion of each component of the waste slag backfill soil, and ensuring the effect and accuracy of the mixing of the waste slag backfill soil.
