Description

Technical Field

[0001] This utility model relates to the field of cement packaging technology, specifically a cement bagging machine with a small rotor structure. Background Technology

[0002] Currently, impeller-type discharge devices are commonly used in cement bagging machines because their ash discharge capacity is significantly higher than that of spiral discharge devices. In practical applications, the inventors of this application have discovered that when the amount of particles between the blades of the impeller in the impeller-type discharge device increases, the discharge rate also increases. Therefore, improving the amount of particles between the blades of the impeller becomes crucial for increasing the discharge rate of the impeller-type discharge device. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cement bagging machine with a small rotor structure.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A cement bagging machine with a small rotor structure includes a main frame, a feed hopper on the main frame, a rotor hopper connected to the bottom of the feed hopper, a rotor impeller inside the rotor hopper, the rotor impeller including a main shaft and an impeller fixed coaxially with the main shaft, wherein one end of the main shaft extends through the side wall of the rotor hopper and is connected to a transmission mechanism, and a small rotor mechanism is provided inside the rotor hopper and located in the area behind the impeller.

[0006] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0007] Adding a small rotor mechanism can drive the particles behind the rotor impeller to move, and under the centrifugal action of the small rotor mechanism, more particles reach the conveying blade area and even the outer edge of the rotor impeller, thereby increasing the amount of particles between the effective blades and ultimately achieving effective discharge.

[0008] As a preferred embodiment, a further technical solution of this utility model is:

[0009] Preferably, the small rotor mechanism includes a rotor shaft that is rotatably disposed with respect to the side wall of the rotor compartment. One end of the rotor shaft extends out of the side wall of the rotor compartment and is connected to a drive mechanism, and the other end of the rotor shaft is provided with an impeller.

[0010] Preferably, the impeller includes a mounting plate coaxially arranged with the rotor shaft, and blades arranged in a circumferential array on the mounting plate.

[0011] Preferably, the mounting plate has a ring-shaped structure.

[0012] Preferably, the blades have a rectangular plate structure.

[0013] Preferably, the blade is fixed vertically to the mounting plate.

[0014] Preferably, the blade tip extends a predetermined length outward from the mounting plate.

[0022] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown in the figure, this embodiment provides a cement bagging machine with a small rotor structure, including a main frame 1, a feeding bin 2 on the main frame 1, a rotor bin 3 connected to the bottom of the feeding bin 2, a rotor impeller inside the rotor bin 3, the rotor impeller including a main shaft and an impeller fixed coaxially with the main shaft, wherein one end of the main shaft protrudes through the side wall of the rotor bin 3 and is connected to a transmission mechanism 4, and a small rotor mechanism is provided inside the rotor bin 3 and located in the area behind the impeller.

[0024] In practice, the term "small" in this application refers to the fact that the overall size of the small rotor mechanism is smaller than that of the rotor impeller. The small rotor mechanism includes a rotor shaft 5 that is rotatably mounted to the side wall of the rotor housing 3. One end of the rotor shaft 5 extends out of the side wall of the rotor housing 3 and is connected to a drive mechanism. The other end of the rotor shaft 5 is provided with an impeller 6. The drive mechanism can be a servo motor used to drive the rotor shaft to rotate.

[0025] The impeller 6 includes a mounting plate 7 coaxially arranged with the rotor shaft 5, and blades 8 arranged in a circumferential array on the mounting plate 7.

[0026] Mounting plate 7 has a ring-shaped structure.

[0027] The blade 8 has a rectangular plate structure.

[0028] The blade 8 is vertically fixed to the mounting plate 7.

[0029] The blade 8 extends a predetermined length outward from the mounting plate 7.

[0030] The small rotor mechanism is located in the upper area of ​​rotor chamber 3, that is, near the upper feed port of rotor chamber 3.

[0031] See Figure 5 The figure shows the particle volume fraction cloud map obtained after adding the small rotor mechanism in the simulation. The figure shows the volume fraction of particles in different regions. For example, the blue area (mainly the area between the blades in the rotor impeller) has a volume fraction between 0 and 0.1. Therefore, it can be seen that adding the small rotor mechanism can drive the particles behind the rotor impeller to move. Under the centrifugal action of the small rotor mechanism, more particles reach the conveying blade area and even the outer edge of the rotor impeller, thereby increasing the effective particle amount between the blades and finally achieving effective discharge.

[0032] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
