The existing feeding chute is vertically arranged at the feeding end of the pit belt conveyor, resulting in a large amount of dust flying, and the dust collection efficiency of the dust collector is relatively low and the effect is not obvious. Summary of the Utility Model

[0004] The purpose of this application is to provide a dust reduction device for feeding a pit belt conveyor to solve the problems that the existing feeding chute is vertically arranged at the feeding end of the pit belt conveyor, resulting in a large amount of dust flying, the dust collection efficiency of the dust collector is relatively low and the effect is not obvious.

[0005] To solve the above technical problems, this application provides a dust reduction device for feeding a pit belt conveyor, including a pit body, a pit belt conveyor is arranged in the pit body, a feeding chute is arranged above the pit belt conveyor, a sealing plate is arranged between the bottom of the feeding chute and the pit belt conveyor, the sealing plate is obliquely arranged above the pit belt conveyor, a feeding port is opened on the side of the feeding chute, a dust collection pipe is arranged on the pit belt conveyor, and one end of the dust collection pipe far away from the feeding port is connected with a dust collector.

[0006] It should be noted that a carrying roller is arranged on the pit belt conveyor near the feeding port through a bracket.

[0007] Furthermore, it is worth noting that a sealing cover is also arranged above the pit belt conveyor, and the bottom of the feeding chute passes through the sealing cover and extends to the pit belt conveyor.

[0008] As a preferred implementation manner, the dust collection pipe passes through the sealing cover and extends to the feeding port.

[0009] It should be noted that the diameter of the dust collection pipe is 200 cm.

A feeding chute is arranged above the belt conveyor. The feeding end of the unloader is directly arranged above the pit belt conveyor. The cement clinker on the unloader directly falls onto the pit belt conveyor through the feeding chute, and the clinker is conveyed by the pit belt conveyor. A sealing plate is arranged between the bottom of the feeding chute and the pit belt conveyor to shield the bottom of the feeding chute through the sealing plate. The sealing plate is inclined and arranged above the pit belt conveyor. A feeding port is opened on the side of the feeding chute.

[0015] 3. A roller is arranged at the feeding port, which can slow down the falling of the clinker and buffer the material, so that the material slowly falls into the middle of the pit belt conveyor, avoiding the deviation of the feeding point, solving the problem of belt deviation caused by the deviation of the feeding point, reducing the failure of belt tearing caused by belt deviation, ensuring normal feeding, and improving the reliability and working efficiency of the equipment.

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings.

[0020] The core of this application is to provide a dust reduction device for charging a pit belt conveyor, which solves the problem that the existing feeding chute is vertically arranged with the feeding end of the pit belt conveyor, resulting in a large amount of dust, low dust collection efficiency of the dust collector, and obvious effect.

[0021] Figure 1 The following is a schematic structural diagram of a dust reduction device for charging a pit belt conveyor provided by the present utility model. See Figure 1 as shown.

[0022] A dust reduction device for charging a pit belt conveyor includes a pit body 1 opened on the ground. A pit belt conveyor 2 is arranged in the pit body 1. A support frame is arranged at the bottom of the pit belt conveyor 2 to facilitate the support of the pit belt conveyor 2, so that the pit belt conveyor 2 can convey materials in the pit body 1. A feeding chute 3 is arranged above the pit belt conveyor 2. The feeding end of the unloader is directly arranged above the pit belt conveyor 2. The cement clinker on the unloader directly falls onto the pit belt conveyor 2 through the feeding chute 3, and the clinker is conveyed by the pit belt conveyor 2. A sealing plate 4 is arranged between the bottom of the feeding chute 3 and the pit belt conveyor 2 to shield the bottom of the feeding chute 3 with the sealing plate 4. The clinker first falls onto the sealing plate 4 and then slowly discharges from the feeding chute 3. The sealing plate 4 is inclined above the pit belt conveyor 2. A feeding port 5 is opened on the side of the feeding chute 3. The bottom of the feeding chute 3 is shielded with the sealing plate 4, and the sealing plate 4 is inclined above the pit belt conveyor 2, so that the clinker slowly falls onto the pit belt conveyor 2 through the feeding port 5 opened on the side. The falling of the material reduces the height difference and avoids splashing a large amount of dust due to vertical falling.

[0023] In order to further treat the dust generated during feeding, a dust collection pipe 6 is arranged on the pit belt conveyor 2. One end of the dust collection pipe 6 far from the feeding port 5 is connected to a dust collector (the dust collector is not shown in the figure). The dust collector takes away the dust through the dust collection pipe 6 and then conducts centralized treatment. At the same time, in order to prevent dust from polluting the working space, as a preferred implementation manner, a sealing cover 8 is also arranged above the pit belt conveyor 2. The bottom of the feeding chute 3 passes through the sealing cover 8 and extends to the pit belt conveyor 2. The dust generated when the cement clinker falls from the unloader onto the pit belt conveyor 2 is isolated in the sealing cover 8, and then the dust collector conducts centralized treatment on the dust to prevent the dust generated during feeding from polluting the working space because it cannot be absorbed in time.

[0024] In this embodiment, as a preferred implementation, the dust collection pipe 6 passes through the sealing cover 8 and extends to the blanking opening 5. The dust collection pipe 6 is arranged close to the blanking opening 5, so that the dust generated during feeding can be absorbed more timely, and then centrally processed by the dust collector.

[0025] To further increase the wind force for dust absorption, as a preferred implementation, the diameter of the dust collection pipe 6 is 200 cm. Changing the original diameter of the dust collection pipe from 400 cm to 200 cm, and arranging the dust collection pipe 6 close to the blanking opening 5, can enable the dust collector to fully play its role in absorbing dust.

[0026] In this embodiment, as a preferred implementation, a carrying roller 7 is arranged on the pit belt conveyor 2 close to the blanking opening 5 through a bracket. Arranging the carrying roller 7 at the blanking opening 5 can slow down the falling of the clinker, buffer the material, make the material slowly fall into the middle of the pit belt conveyor 2, avoid the deviation of the material dropping point, solve the problem of belt deviation caused by the deviation of the material dropping point, reduce the failure of belt tearing due to belt deviation, ensure normal feeding, and improve the reliability and working efficiency of the equipment.

[0027] As a preferred implementation, the sealing plate 4 is a steel plate fixedly connected to the bottom of the blanking chute 3. The steel plate shields the original blanking opening, so that the clinker slowly falls along the inclined sealing plate 4, reducing the generation of dust.

[0028] A dust reduction device for feeding on a pit belt conveyor provided by this application includes a pit body 1 opened on the ground. A pit belt conveyor 2 is arranged in the pit body 1. A blanking chute 3 is arranged above the pit belt conveyor 2. The discharging end of the unloader is directly arranged above the pit belt conveyor 2. The cement clinker on the unloader directly falls onto the pit belt conveyor 2 through the blanking chute 3, and the pit belt conveyor 2 conveys the clinker. A sealing plate 4 is arranged between the bottom of the blanking chute 3 and the pit belt conveyor 2. The bottom of the blanking chute 3 is shielded by the sealing plate 4. The clinker first falls onto the sealing plate 4 and then slowly discharges from the blanking chute 3, so that the clinker slowly falls into the pit belt conveyor 2 through the blanking opening 5 opened on the side. The falling of the material reduces the height difference and avoids a large amount of dust being splashed up by vertical falling. The dust generated when the cement clinker falls onto the pit belt conveyor 2 from the unloader is isolated in the sealing cover 8, and then the dust is centrally processed by the dust collector, preventing the dust generated during feeding from polluting the working space due to untimely absorption. Arranging the carrying roller 7 at the blanking opening 5 can slow down the falling of the clinker, buffer the material, make the material slowly fall into the middle of the pit belt conveyor 2, avoid the deviation of the material dropping point, solve the problem of belt deviation caused by the deviation of the material dropping point, reduce the failure of belt tearing due to belt deviation, ensure normal feeding, and improve the reliability and working efficiency of the equipment.
