Description

Technical Field

[0001] The utility model belongs to the technical field of paste filling, and particularly relates to a paste filling pipeline mixer. Background Technique

[0002] Paste filling mining can not only effectively solve the problem of coal pressing under "three under one over" in coal mines, but also deal with the environmental pollution problem caused by coal gangue. Therefore, paste filling mining is widely used in more and more coal mining enterprises.

[0003] At present, in the process of longwall paste filling mining, in order to make the paste reach the initial setting state quickly, a setting accelerator is generally added to the filling paste, so as to shorten the solidification waiting time, reach the condition of moving the support as soon as possible, and improve the filling mining efficiency.

[0004] Since adding the setting accelerator when mixing the paste on the ground will cause the paste to solidify in the pipeline and result in a pipe blockage accident, most of them choose to add the setting accelerator at the end of the filling pipeline. However, directly adding the setting accelerator at the end of the filling pipeline will cause the filling paste and the setting accelerator not to be fully stirred and fused, resulting in unstable paste performance and low filling mining efficiency. Content of the Utility Model

[0005] The utility model provides a paste filling pipeline mixer for the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A paste filling pipeline mixer includes a pipe body. A plurality of groups of blades are evenly and fixedly installed inside the pipe body. A setting accelerator inlet is arranged at a position of the pipe body close to the inlet end. Quick connectors are fixedly arranged at both ends of the pipe body for connecting with the filling pipeline.

[0008] Further, the blade is composed of two steel plates twisted along the length direction and welded together. A notch is opened in the middle of the steel plate, and the positions of the notches on the two steel plates are opposite. The two steel plates are assembled by docking the notches on the two steel plates, and the two steel plates are arranged perpendicular to each other.

[0009] Furthermore, the odd-numbered blades and the even-numbered blades are arranged at an angle of 45°.

[0010] Furthermore, the inner diameter of the pipe body is the same as the outer diameter of the blade.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The utility model can stir the paste and the accelerator in the pipe body through multiple groups of staggered blades, so that the paste and the accelerator are fully fused, shorten the initial setting time of the paste, make the performance of the filling paste stable, and improve the filling mining efficiency.

[0018] In order to further elaborate on the technical solution of the utility model, the utility model will be further described below through embodiments.

[0019] As Figures 1 to 4 shown, a paste filling pipeline mixer includes a pipe body 1, and multiple groups of blades 2 are uniformly and fixedly installed inside the pipe body 1. The inner diameter of the pipe body 1 is the same as the outer diameter of the blades 2. The odd-numbered blades 2 and the even-numbered blades 2 are arranged at an angle of 45°. An accelerator inlet 3 is provided at a position near the inlet end of the pipe body 1, and quick connectors 4 are fixedly provided at both ends of the pipe body 1 for connecting to the filling pipeline.

[0020] The blade 2 is composed of two steel plates 201 that are twisted along the length direction and welded together. A notch 202 is opened in the middle of the steel plate 201, and the positions of the notches 202 on the two steel plates 201 are opposite. The assembly of the two steel plates 201 is completed by the fork connection of the notches 202 on the two steel plates 201, and the two steel plates 201 are arranged perpendicular to each other.

[0021] The main features and advantages of the present utility model have been shown and described above. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms.
