Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material feeding devices, and in particular relates to a material feeding structure of a limestone batching warehouse. Background Art
[0002] In the production process of cement, batching silos are needed. Batching silos are used to receive, store and discharge the powdered raw materials of each component required by the formula to ensure continuous production. In order to facilitate the discharge of raw materials, a conical discharge pipe is usually set at the bottom of the batching silo, and the raw materials flow out from the discharge pipe. There are some problems with the existing discharge pipe. Due to the high moisture content of the raw materials and the static state of the materials after stopping the mill, the raw materials in the conical part of the bottom of the silo and the inner wall of the discharge pipe have poor fluidity and are easily adhered to the conical part of the bottom of the silo and the inner wall of the discharge pipe to form a crust, resulting in the reduction of the discharge port and causing blockage. In addition, due to the segregation of materials during the discharge process, fine powder and large lumps are discharged unevenly. When large lumps are discharged in a concentrated manner, the vibration of the mill is often aggravated, which directly affects the grinding efficiency of the mill and the quality of raw materials. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a limestone batching warehouse unloading structure for solving the technical problems that the current unloading structure is prone to blockage and uneven unloading of large and small blocks.
[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a limestone batching warehouse unloading structure, which includes a conical unloading pipe arranged at the bottom of the warehouse, a first unloading port arranged at the bottom of the unloading pipe, and at least two auxiliary unloading pipes, and a second unloading port is arranged at the bottom of the auxiliary unloading port; the auxiliary unloading pipes are arranged on both sides of the first unloading port, and the axes of the auxiliary unloading pipes and the first unloading port are parallel to each other; flow regulating valves are arranged in the first unloading port and the second unloading port.
[0005] Preferably, the auxiliary feeding pipes are arranged at the same height on the side wall of the feeding pipe.
[0006] Preferably, the first feed opening and the second feed opening are at the same height.
[0007] Preferably, the horizontal distance between the second feed opening and the first feed opening is 600 mm.
[0008] Preferably, the flow regulating valve adopts a rod gate.
[0009] Preferably, the feed pipe is in the shape of an inverted cone.
[0010] Preferably, the feed pipe is in a pyramid shape.
[0011] The beneficial effects of adopting the technical solution of the utility model are:
[0012] The utility model arranges auxiliary discharge pipes on the discharge pipe, which are distributed on both sides of the first discharge port. When discharging raw materials, raw materials flow out from the three discharge ports at the same time, thereby increasing the flow of raw materials at the bottom of the warehouse and the inner wall of the discharge pipe, reducing the phenomenon of crusting, and thus reducing the possibility of material blockage; and, the arrangement of the three discharge ports, even if a certain segregation phenomenon occurs, since the raw materials flow out from different discharge ports, it is avoided that fine powder or large blocks are discharged at the same time, thereby improving the uniformity of the force of discharging raw materials, and thus will not affect the grinding efficiency of the mill and the quality of raw materials.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0019] The specific embodiments are as follows:
[0020] Embodiment 1, as Figure 1 , 2 As shown, a limestone batching warehouse unloading structure includes a unloading pipe 2. The unloading pipe 2 adopts a conical style, which can be an inverted cone or an inverted cone, so as to facilitate the outflow of the raw materials in the batching warehouse 1. The unloading pipe 2 is arranged at the bottom of the batching warehouse 1. A first unloading port 21 is arranged at the lower end of the unloading pipe 2, and the raw materials in the batching warehouse 1 are discharged from the first unloading port 21.
[0021] Auxiliary discharge pipes 3 are arranged on both sides of the first discharge port 21, at least two auxiliary discharge pipes 3 are arranged, and a second discharge port 31 is arranged at the bottom of the auxiliary discharge pipe 3 for discharging raw materials. In this embodiment, two auxiliary discharge pipes 3 are arranged, the axes of the second discharge port 31 and the first discharge port 21 are parallel to each other, and the first discharge port 21 and the second discharge port 31 are both vertically downward, and a conveyor belt 5 is arranged below the discharge port to facilitate the discharge of raw materials to the mill.
[0022] Flow regulating valves 4 are provided at the first discharge port 21 and the second discharge port 31 for adjusting the speed of raw material discharge, and different openings are set for raw materials of different particle sizes to improve the scope of application.
[0023] When the unloading structure of a limestone batching warehouse of the present embodiment is used, the raw material flows from the batching warehouse to the unloading pipe 2, and is discharged from the first unloading port 21 and the second unloading port 31, and falls on the conveyor belt 5 for transportation, and is transported to the mill for subsequent production. When unloading from one unloading port in the prior art, the raw material can only be unloaded when it is collected at a single discharge port, so that the raw material at the bottom of the warehouse and the wall of the unloading pipe 2 has poor fluidity and is prone to crusting, which will cause the unloading port to shrink and cause blockage; while in the present embodiment, the number of unloading ports is increased from the original one to three, which increases the flow of raw materials at the bottom of the warehouse connected to the unloading pipe 2 and the inner wall of the unloading pipe 2, reduces the crusting phenomenon, and thus reduces the possibility of blockage. Furthermore, even when a certain degree of segregation occurs in the raw materials in the batching warehouse 1, since the raw materials will be discharged from different positions such as the first discharge port 21 and the second discharge port 31, the particle size of the segregated raw materials at different discharge port positions will also be different. This can make up for the problem that only raw materials of the same particle size can be discharged at the same time when there is only one discharge port, and promote the uniformity of the particle size of the discharged raw materials, so as to avoid the problem that the vibration of the mill is aggravated when large pieces of material are discharged in a concentrated manner, which directly affects the grinding efficiency of the mill and the quality of the raw materials.
[0024] Furthermore, two auxiliary discharge pipes 3 are arranged on the left and right sides of the first discharge port 21, and the positions where they are connected to the discharge pipe 2 are at the same height on the side wall of the discharge pipe 2, so that the first discharge port 21 and the two second discharge ports 31 are in the same straight line, which facilitates the discharge to be concentratedly lowered onto the conveyor belt 5.
[0025] Furthermore, the second discharge port 31 and the first discharge port 21 are at the same height, so that the discharge positions are at the same distance from the conveyor belt 5, thereby ensuring the consistency of discharge.
[0026] In this embodiment, the horizontal distance between the two second material discharge openings 31 and the first material discharge opening 21 is 600 mm, so as to ensure that the material discharge openings are independent of each other and do not interfere with each other.
[0027] Furthermore, the flow regulating valve 4 at the discharge port adopts a rod valve. The rod valve is suitable for conveying and feeding processes of small and medium-sized solid and block materials, and is suitable for controlling materials ≤50 mm. In this embodiment, the rod valve can be a single-layer, double-layer, manual, pneumatic, or electro-hydraulic rod valve, or a manual single-layer rod valve or a double-layer electro-hydraulic rod valve.
[0028] In other embodiments, guide sleeves for guiding flow are further provided at the first discharge port and the second discharge port to reduce the distance between the raw materials and the conveyor belt during discharge. Other structures are not described in detail here.
[0029] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
