Description

Technical Field

[0001] The utility model relates to an impeller coal feeder, in particular to a precise feeding impeller coal feeder applied in the field of coal feeders. Background Art

[0002] The impeller coal feeder is one of the main equipment in the slot-type coal unloading ditch of a thermal power plant. It can move along the longitudinal track of the coal ditch and use the horizontally rotating impeller to push the coal onto the coal conveyor belt in a quantitative, uniform and continuous manner. This device is used in coal, mining, metallurgy, building materials, chemical industry and other industries that need to load, unload and transport bulk materials.

[0003] When in use, the impeller coal feeder will move longitudinally through the walking mechanism, but it is easy to run empty during walking, and it is impossible to feed coal at a fixed point. Moreover, the impeller cannot be removed after installation. When the impeller fails, it is inconvenient for the staff to repair it. Utility Model Content

[0004] In view of the above-mentioned existing technology, the technical problem to be solved by the present invention is that the existing impeller coal feeder is prone to running empty when moving longitudinally, cannot feed coal at a fixed point, and the impeller cannot be removed after installation, making it inconvenient to repair it.

[0006] In the above-mentioned precision feeding impeller coal feeder, when in use, coal can be fed while moving longitudinally along the coal ditch without idle travel, and coal can also be fed at a fixed point. The coal amount can be adjusted evenly, stably and reliably. The impeller can be moved through the impeller removal mechanism, which is convenient for its later maintenance and easy to use.

[0007] As a further improvement of the present application, the walking structure includes a walking reducer and two walking wheels. The walking reducer is fixedly mounted on the front end of the front side beam. The walking wheels are rotatably connected to the inner cavity of the side beam. The upper end of the side beam is fixedly connected to a cover plate, which is located directly above the walking wheels.

[0008] As a further improvement and supplement to the present application, a coupling is fixedly connected between the travel wheels, and the output end of the travel reducer is fixedly connected to the front travel wheel.

[0009] As a further improvement supplement to the present application, the left end of the side beam is fixedly connected with an anti-collision buffer block, and the ends of the two side beams away from each other are fixedly connected with a coupling guard, which is located at the end of the walking wheel away from the walking reducer.

[0010] As a further improvement of the present application, the lower coal hopper includes a coal hopper body and a machine cover shell. The cross section of the machine cover shell is semicircular. The front end of the impeller blade is located inside the machine cover shell, and the radius of the machine cover shell is larger than the radius of the impeller blade.

[0011] As another improvement of the present application, a nameplate is fixedly connected to the front end of the front side beam, and a position sensor is fixedly connected to the front end of the nameplate.

[0012] To sum up, in actual application, the travel wheel is driven to rotate by the travel reducer, and the coupling drives the two travel wheels to rotate at the same time, so that the coal feeder moves longitudinally along the coal ditch. At the same time, the driving reducer can drive the impeller blades to rotate, thereby continuously and evenly shifting the coal in the gap-type coal ditch into the lower coal hopper. When the impeller blades need maintenance, the impeller blades are moved out of the lower coal hopper through the impeller removal mechanism, thereby facilitating maintenance. The upper end of the impeller is shielded by the impeller opening and closing assembly, and the dust removal system is started at the same time to adsorb the smoke and dust, thereby improving the working environment.

DETAILED DESCRIPTION

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1 、 Figure 2 and Figure 3 The figure shows: a precise feeding impeller coal feeder, comprising two side beams 1, two walking structures 2 are fixedly installed between the two side beams 1, a middle frame 3 with a belt removal mechanism is fixedly connected between the two side beams 1, the upper end of the middle frame 3 with the belt removal mechanism is fixedly connected to a coal hopper assembly, the coal hopper assembly comprises a lower coal hopper 4, an impeller removal mechanism is fixedly connected inside the lower coal hopper 4, the impeller removal mechanism comprises a support plate 5, the front end of the support plate 5 is fixedly connected to two cylinders 13, the rear end of the cylinder 13 is fixedly connected to the front inner wall of the lower coal hopper 4, and the support plate 5 is fixedly connected to the front inner wall of the lower coal hopper 4. The lower end is slidingly connected to the inner wall of the lower coal hopper 4, the upper end of the support plate 5 is fixedly connected to the driving reducer 6, and the output shaft of the main driving reducer 6 is fixedly connected to the impeller blade 7. The right ends of the two side beams 1 are jointly fixedly connected to the dust removal system 8. The dust removal system 8 is an existing structure and can be selected according to usage requirements. No further details will be given here. The front end of the dust removal system 8 is fixedly connected to the escalator 9, and the dust removal system 8 and the upper end of the side beam 1 are jointly fixedly connected to the impeller opening and closing assembly 10. The impeller blade 7 is located directly below the impeller opening and closing assembly 10.

[0024] Figure 1 and Figure 3 It is shown that: the walking structure 2 includes a walking reducer 201 and two walking wheels 202. The walking reducer 201 is fixedly installed at the front end of the front side beam 1. The walking wheel 202 is rotatably connected to the inner cavity of the side beam 1. The upper end of the side beam 1 is fixedly connected with a cover plate to prevent dust from entering the inside of the walking wheel 202 and causing the walking wheel 202 to get stuck. The cover plate is located directly above the walking wheel 202. A coupling 203 is fixedly connected between the walking wheels 202. The output end of the walking reducer 201 is fixedly connected to the front walking wheel 202. The left end of the side beam 1 is fixedly connected with an anti-collision buffer block 204. The end away from the two side beams 1 is fixedly connected with a coupling guard 205. The coupling guard 205 is located at the end of the walking wheel 202 away from the walking reducer 201.

[0025] Figure 4 and Figure 5It is shown that the lower coal hopper 4 includes a coal hopper body and a machine cover shell. The cross section of the machine cover shell is semicircular. The front end of the impeller blade 7 is located in the machine cover shell, and the radius of the machine cover shell is larger than the radius of the impeller blade 7.

[0026] During use, the travel wheel 202 is driven to rotate by the travel reducer 201, and the coupling 203 drives the two travel wheels 202 to rotate at the same time, so that the coal feeder moves longitudinally along the coal ditch. At the same time, the driving reducer 6 can drive the impeller blade 7 to rotate, thereby continuously and evenly shifting the coal in the gap-type coal ditch into the lower coal hopper 4. When the impeller blade 7 needs maintenance, the support plate 5 is pushed out of the lower coal hopper 4 by starting the cylinder 13, thereby moving the impeller blade 7 out of the lower coal hopper 4, making it easier to maintain it. The upper end of the impeller blade 7 is blocked by the impeller opening and closing assembly 10, and the dust removal system 8 is started to adsorb the smoke and dust to improve the working environment.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
