Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a raw material batching system. Background Art

[0002] Cement raw material is a material made of lime raw material, clay raw material and a small amount of correction raw material (sometimes mineralizer, seed crystal, etc. are added, and coal is also added during vertical kiln production). The material is ground to a certain fineness in proportion and is called cement raw material.

[0003] In the prior art, the batching of raw materials often requires multiple devices to be carried out in steps. Since raw materials involve many types of raw materials (especially the production of special cement), different types of raw materials need to be processed separately and finally transported to one location for final mixing. This process involves a lot of redundant work, such as raw material weighing and transportation. Therefore, the current raw material batching process is relatively complicated and inefficient.

[0004] For this purpose, our company provides a highly integrated batching system. After all raw materials are proportioned in one system, they are finally discharged in a unified manner, which greatly reduces the workload and improves efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, the utility model provides a technical solution: a raw material batching system, including a base 1, on which a stirring tower 2, a batching system 3, a first elevator 4, a mixing bin 5, a second elevator 6 and a feeder 7 are respectively arranged. As for the first and second elevators 4 / 6, a belt transmission structure or a hopper conveying structure can be adopted, and the above two structures are both existing technologies.

[0024] The feeder 7 conveys the raw materials to the mixing bin 5 through the second elevator 6. The mixing bin 5 includes a bin body 51. A plurality of partitions are arranged in the bin body 51. The partitions divide the bin body 51 into a plurality of small bins 52. The advantage of providing a plurality of small bins 52 is that the raw materials are contained in partitions, thereby avoiding a large amount of raw materials from piling up in one place, causing blockage of the raw materials or uneven mixing. A conveyor belt 53 is arranged under the bin body 51.

[0025] like Figure 1 , 3 As shown, the second elevator 6 is a rotatable structure, and its rotation center is located directly below the feeder 7 (the second elevator 6 is driven to rotate by a motor). A rotating bracket 12 is provided at the bottom of the second elevator 6, and an arc-shaped slide groove 13 is provided on the base 1. The rotating bracket 12 is slidably installed on the arc-shaped slide groove 13. The mixing bin 5 transports the raw materials to the batching system 3 through the first elevator 4. The purpose of designing the second elevator 6 as a rotatable structure is to facilitate its discharge of raw materials to each small bin 52.

[0026] like Figure 1-2 As shown, the batching system 3 includes a first feed bin 31 and a second feed bin 32 located at the top, wherein the first feed bin 31 is located directly below the first elevator 4, and the second feed bin 32 is located directly below the material conveyor 10. The bottoms of the first feed bin 31 and the second feed bin 32 are commonly connected to a batching box 34, and a stirrer is provided in the batching box 34, which is not shown in the figure. The top of the batching box 34 is provided with a metering device 33 for weighing the materials in the first feed bin 31 and the second feed bin 32, and the bottom of the batching box 34 is provided with a discharge port 35.

[0027] like Figure 1 As shown, a material conveyor 10 (using a screw conveyor shaft) is provided at the bottom of the mixing tower 2 , and a discharge port of the material conveyor 10 faces the batching system 3 .

[0028] The feeding bin 8 lifts the material to the top entrance of the mixing tower 2 through the lifting pipe 9.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0030] When in use, cement raw materials and clay materials are poured into the feeding bin 8, then lifted to a high place through the lifting pipe 9, and sent to the mixing tower 2 for mixing. After mixing, they are sent to the first feeding bin 31 through the material conveyor 10 at the bottom.

[0031] On the other hand, the corrected raw materials are simultaneously poured into the feeder 7, and then sent to the mixing bin 5 through the second elevator 6. After the corrected raw materials are mixed in the mixing bin 5, they are transported out by the ventilated conveyor belt conveyor 53 and transferred to the first elevator 4, and sent to the second feeding bin 32 through the first elevator 4.

[0032] After being weighed by the metering device 33 , the above raw materials are introduced into the batching box 34 , and after secondary mixing in the batching box 34 , they are discharged through the discharge port 35 .

[0033] In summary, the raw material batching system integrates multiple mixing towers and mixing silos in one place, and connects the mixing tower, mixing silo and batching system through a hoist to facilitate loading. The mixing tower and mixing silo work synchronously in the early stage, and the relevant raw materials are pre-mixed and finally sent to the batching system for weighing and batching, and finally the materials are discharged uniformly. The whole system has a high degree of integration and the efficiency has been significantly improved.
