Description

Technical Field

[0001] The utility model belongs to the technical field of material dragging devices, and more specifically relates to a blowout prevention material self-compensating constant material dragging device. Background Art

[0002] In the batching process of sintering production, a certain amount of quicklime and other materials need to be added. There are two traditional ways of batching lime. One is as follows: Figure 4 As shown, a star-shaped ash discharge valve 11 is installed under the ash storage hopper 5, and the star-shaped ash discharge valve 11 rotates to feed the material. Affected by the structure of the star-shaped ash discharge valve 11, the lime is discharged to the conveyor belt 3 in a wave-like distribution state, which leads to uneven mixing of materials during the batching process, affecting the stability of the moisture and composition of the entire material and the air permeability of the mixture; the other is as follows Figure 5 As shown, the gate valve 51 is used to discharge the material directly from the ash storage hopper 5 to the conveyor belt 3. Due to the gravity pressure of the material in the main hopper and the fine particle size and strong fluidity of the quicklime, the material outlet will frequently spray the material. Utility Model Content

[0003] The purpose of the utility model is to provide a self-compensating constant material dragging device for preventing material spraying in view of the shortcomings of the existing technology, so as to solve the problems of the existing technology in which the material distribution state is wavy and the material dragging outlet frequently sprays material.

[0031] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] This embodiment provides a self-compensating constant dragging device for preventing blowout materials, such as Figure 1 Shown, including:

[0033] The main hopper 1 is a funnel-shaped structure, and a star-shaped ash discharge valve 11 is provided at the discharge port of the main hopper 1;

[0034] The auxiliary hopper 2 is a funnel-shaped structure, which is arranged below the star-shaped ash discharge valve 11 and is provided with at least one first weighing sensor 23, which is used to measure the weight of the material in the auxiliary hopper 2;

[0035] The conveyor belt 3 is arranged below the auxiliary hopper 2;

[0036] The controller is used to receive the weight information of the first weighing sensor 23 and control the rotation speed of the star-shaped ash discharge valve 11.

[0037] During specific implementation, the material in the main hopper 1 is fed into the auxiliary hopper 2 by the rotation of the star-shaped ash discharge valve 11; the material in the auxiliary hopper 2 is dragged forward by the rotation of the conveyor belt 3; when the weight of the material in the auxiliary hopper 2 is lower than the set lower limit, the controller controls the star-shaped ash discharge valve 11 to start feeding; when the weight of the material in the auxiliary hopper 2 exceeds the set upper limit, the controller controls the star-shaped ash discharge valve 11 to stop rotating, and repeats this operation to achieve automatic compensation of the material in the auxiliary hopper 2. This improves the stability of the discharge amount and the uniformity of the material mixing, promotes the quality of the sintered ore product, and eliminates the frequent spraying during discharge. In this embodiment, the material is lime, the lower limit is set to 0.5 tons, and the upper limit is set to 3.5 tons.

[0038] Further, such as Figure 2 As shown, the discharge port of the auxiliary hopper 2 is a square hopper 21. Specifically, the shape of the square hopper 21 matches the shape and structure of the conveyor belt 3, and the material quantity is large, uniform and stable when feeding to the belt for transportation; in addition, the shape of the square hopper 21 is conducive to the production and use of the adjustment plug plate 22.

[0039] Optionally, the square bucket 21 has a size of 0.6m×0.6m×1m, and the width of the conveyor belt 3 is 0.8m. Specifically, the width of the square bucket 21 is slightly smaller than the width of the conveyor belt 3 to prevent the material from exceeding the range of the conveyor belt 3 when it is discharged onto the conveyor belt 3.

[0040] Furthermore, the upper portion of the auxiliary hopper 2 is conical, with an upper end dimension of Φ2.5m, a lower end dimension of Φ0.6m, and a height of 3m. Specifically, the conical upper portion can better receive and store the material (lime) discharged from the discharge valve.

[0041] Furthermore, the square hopper 21 is provided with a material outlet on the sidewall facing the conveyor belt 3. The material outlet is equipped with an adjustment plate 22 that can be moved up and down to adjust the size of the material outlet. Specifically, the adjustment plate 22 can adjust the material discharge capacity of the auxiliary hopper 2 as needed. In this embodiment, slideways are provided on both sides of the material outlet, and the adjustment plate 22 is slidably connected to the material outlet via the slideways.

[0042] Further, such as Figure 3 As shown, the conveyor belt 3 is provided with a second weighing sensor, which is used to measure the weight of the material on the conveyor belt 3. Specifically, the weight of the material on the conveyor belt 3 can be used to determine whether the unloading amount meets the process requirements.

[0043] Furthermore, the controller is also used to receive the weight information measured by the second weighing sensor and to control the speed of the conveyor belt 3. In specific implementation, the conveyor belt 3 can automatically adjust the speed of the drag material according to the value changes of the second weighing sensor to achieve accurate and constant material distribution. (As shown in Figure 6)

[0044] Furthermore, there are multiple first weighing sensors 23, which are evenly arranged around the auxiliary hopper 2. Specifically, evenly arranging multiple first weighing sensors 23 can improve measurement accuracy and reduce errors. In this embodiment, there are three first weighing sensors 23.

[0045] Further, such as Figure 3 As shown, the first load cell 23 is connected to the load-bearing structural beam at its lower portion and to the auxiliary hopper 2 at its upper portion. In this embodiment, the first load cells 23 are mounted on the load-bearing structural beam 4 at three points evenly distributed around the circumference of the auxiliary hopper 2 (see Figure 4). The special-shaped auxiliary hopper 2 is positioned between the star-shaped ash discharge valve 11 and the conveyor belt 3 and independently mounted on the base 24 of the first load cell 23.

[0046] Furthermore, the discharge port of the main hopper 1 is cylindrical and has a diameter of 0.6m, and the diameter of the star-shaped ash discharge valve 11 is 0.6m. Specifically, the size of the discharge port of the main hopper 1 matches the size of the star-shaped ash discharge valve 11, and the sizes of the two can be adjusted according to actual process requirements.

[0047] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
