Description

Technical Field

[0001] The utility model relates to the technical field of coal powder feeding, in particular to a flow stabilizing mechanism of a stirring device. Background Art

[0002] Usually when the kiln system is in normal production and operation, the coal powder that needs to be transported out will first be carried out from the original storage bin by means of compressed air flow assistance, and then sent to the rotor scale for accurate metering to prevent excessive coal powder from being directly discharged from the original storage bin. At the same time, before unloading, it is generally necessary to dock the discharge end of the storage bin and the feed end of the rotor scale;

[0003] In the prior art, when coal powder falls from the original large bin and is sent into the rotor scale for metering operation, the rotor is in a state of continuous rotation. However, considering that the rotation of the rotor system may easily cause wind to blow inside the rotor scale cavity, at this time, affected by the wind blowing factor, the coal powder may easily flow up to the inside of the discharge pipe, causing the discharge to be not smooth, and it may also easily cause blockage inside the discharge end, and cause a certain amount of pressure on the entire discharge operation. Therefore, a flow stabilizing mechanism of a stirring device is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a flow stabilizing mechanism for a stirring device, so as to solve the problem that when coal powder is fed into a rotor scale in the prior art, the feeding is unstable and not smooth.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A flow stabilizing mechanism of a stirring device comprises an original large bin body, a discharge pipe opening is connected to the lower right position of the original large bin body, a flow-aiding small bin body is arranged at the end of the discharge pipe opening, a rotating shaft is arranged on the upper inner side of the flow-aiding small bin body, a combined cover plate is fixedly connected to the bottom end of the rotating shaft, a conical platform is fixedly connected to the bottom end of the combined cover plate, an electric heating plate is clamped at a position slightly below the arc surface of the conical platform, a limiting sleeve is sleeved on the outside of the rotating shaft, a stirring rod is fixedly connected to the outside of the limiting sleeve, and a driving motor is fixedly installed at the top position of the flow-aiding small bin body.

[0007] Preferably, the bottom of the flow-aiding bin body is connected with a transfer port, the outside of the transfer port is fixedly connected with a flange, and the top surface of the flow-aiding bin body is provided with a combined circular hole groove that is sealed and plugged with a discharge pipe port.

[0009] Preferably, a material guide platform is fixedly connected to the lower inner side of the original large warehouse body, a support ring is fixedly connected to the top of the material guide platform, a material guide ring plate is fixedly connected to the top of the support ring, the lower part of the rotating shaft passes through the interior of the material guide ring plate, and the material guide ring plate is gradually recessed toward the center position.

[0010] Preferably, a threaded clamp is fixedly connected to a position near the center point of the bottom end of the guide ring plate, and a dispersion column head is threadedly connected to the bottom of the threaded clamp.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by providing a flow-aiding small bin body, a limiting sleeve, a stirring rod, a rotating shaft and a driving motor, the flow-stabilizing mechanism of the stirring device can cooperate with the process of bringing the coal powder out of the original large bin.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A flow stabilizing mechanism of a stirring device comprises an original large bin body 1, a discharge pipe opening 2 is connected to the lower right position of the original large bin body 1, a flow-aiding small bin body 3 is arranged at the end of the discharge pipe opening 2, a rotating shaft 4 is arranged on the upper inner side of the flow-aiding small bin body 3, a combined cover plate 5 is fixedly connected to the bottom end of the rotating shaft 4, a conical platform 6 is fixedly connected to the bottom end of the combined cover plate 5, an electric heating plate 7 is clamped at a position slightly below the arc surface of the conical platform 6, a limiting sleeve 8 is sleeved on the outside of the rotating shaft 4, a stirring rod 9 is fixedly connected to the outside of the limiting sleeve 8, and a driving motor 13 is fixedly installed at the top position of the flow-aiding small bin body 3.

[0020] like Figure 1 and Figure 2 As shown, the bottom position of the flow-aiding small bin body 3 is connected with a transfer material port 16, and the outside of the transfer material port 16 is fixedly connected with a flange 17. The top surface of the flow-aiding small bin body 3 is provided with a combined circular hole groove that is sealed and plugged with the discharge pipe port 2. Before using the entire flow stabilizing mechanism, the feed end of the rotor scale can be quickly connected through the flange 17, so that the entire mechanism can be quickly connected with the inside of the rotor scale; one end of the rotating shaft 4 is connected to the output end of the driving motor 13, the rotating shaft 4 and the limiting sleeve 8 are coaxially arranged, and the stirring rods 9 are distributed in a ring array structure along the center point of the limiting sleeve 8. The stirring rods 9 are arranged in a total of There are 4 groups. When the entire flow stabilizing mechanism starts running, the stirring rod 9 is provided with a total of 4 groups to ensure the stirring range when the entire mechanism starts running; a material guide platform 12 is fixedly connected to the lower inner side of the original large bin body 1, and a support ring 11 is fixedly connected to the top of the material guide platform 12, and a material guide ring plate 10 is fixedly connected to the top of the support ring 11. The lower part of the rotating shaft 4 passes through the interior of the material guide ring plate 10, and the material guide ring plate 10 is gradually recessed toward the center position. When the coal powder falls to the lower half of the interior of the flow-aiding small bin body 3, the setting of the material guide ring plate 10 and the material guide platform 12 will play a dual guiding role in the discharge of the coal powder.

[0021] like Figure 2 and Figure 3As shown, a threaded clamp 14 is fixedly connected to the bottom end of the guide ring plate 10 near the center point, and a dispersion column 15 is threadedly connected to the bottom of the threaded clamp 14.
