Description

Technical Field

[0001] This utility model belongs to the field of blasting engineering technology, specifically relating to a horizontal blast hole ash and slag cleaning device. Background Technology

[0002] Horizontal blast holes formed after rock drilling in mines and tunnels contain a large amount of ash and slag (mainly rock powder, small pieces of gravel, etc.). Because horizontal blast holes are generally characterized by deep holes, small diameters, and near-horizontal angles, it is difficult to remove the ash and slag from the blast holes, which seriously affects the efficiency of subsequent charging and the quality of blasting.

[0003] Currently, after rock drilling is completed in mines and tunnels, workers generally do not clean the blast holes due to the difficulty in cleaning the ash and slag from the blast holes. In addition, the working environment is complex, the space is small, the light is weak, and the strength of the temporary support at the working face is low. A small number of workers simply blow the blast holes with the simple air duct that comes with the pneumatic rock drill. The ash and slag that are ejected back has the characteristics of high speed, high energy and strong diffusion, which can easily cause safety accidents and poses a great safety hazard.

[0004] Meanwhile, due to the large amount of ash and slag in the blast holes, problems such as explosive blockage, insufficient explosive loading, failure of explosive to detonate, and breakage of detonator leads are prone to occur during the charging process, which seriously affect the blasting quality and efficiency. Utility Model Content

[0005] This invention addresses the problem of difficult cleaning of ash and slag from horizontal blast holes, which affects blasting quality and efficiency, by providing a device for cleaning ash and slag from horizontal blast holes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A horizontal blast hole ash and slag cleaning device includes a high-pressure air pipeline, which comprises a horizontal pipeline and a vertical pipeline connected by threads. A buckle is provided on the horizontal pipeline, and a locking block is provided on the vertical pipeline. The buckle and the locking block correspond to each other. The front end of the horizontal pipeline is located inside the horizontal blast hole, and equidistant gaps are provided at the bottom of the horizontal pipeline. The end of the vertical pipeline is connected to the air outlet of an air compressor via a flexible hose. Ash and slag blocking components are provided at the inlets of the horizontal pipeline and the horizontal blast hole, and a pressure regulator is provided in the middle of the vertical pipeline.

[0007] Furthermore, the transverse pipe includes multiple sets of pipe sections, with adjacent pipe sections connected by threads. One or more baffles are rotatably connected to each pipe section, and the baffles correspond to equally spaced gaps. The baffles are evenly distributed on the pipe sections, and multiple limiting blocks are provided on the transverse pipe, with each limiting block corresponding to one of the baffles.

[0008] Furthermore, the included angle between the baffle and the transverse pipe is set to β, and the range of β is set to 0°-30°.

[0009] Furthermore, the transverse pipe is located at the upper part of the horizontal blast hole.

[0010] Furthermore, the ash and slag blocking component includes a fixing ring, which is detachably connected to the transverse pipe. A first slag blocking plate is provided between the upper end of the fixing ring and the wall, and a second slag blocking plate is provided at the lower end of the fixing ring. An ash and slag discharge port is provided between the second slag blocking plate and the wall.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses a horizontal pipe connected to a vertical pipe. The horizontal pipe is set inside the horizontal blast hole. The operator holds the rear end of the horizontal pipe and uses an air compressor to supply high-pressure gas. The pressure regulator adjusts the gas pressure, and the high-pressure gas is sprayed out from the equidistant gaps to achieve rapid cleaning of the horizontal blast hole and improve work efficiency.

[0012] 2. In this utility model, a baffle is rotatably connected at each equidistant gap. The transverse pipe enters the blast hole in a manner that fits the upper part of the blast hole. When the baffle is in the horizontal blast hole, due to the action of the limiting block, the weight of the baffle itself, and the ash and slag, the included angle β between the baffle and the transverse pipe is between 0° and 30°, which is conducive to the efficient discharge of ash and slag.

[0013] 3. The horizontal pipe of this utility model is composed of multiple sets of pipe sections, which can increase or decrease the number of pipe sections according to the length of the horizontal blast hole to meet the requirements of horizontal blast holes of different lengths. It can also adjust the orientation of the longitudinal pipe in 360° according to the position of the horizontal blast hole. Moreover, in the confined space of the underground working face, carrying multiple sets of pipe sections has strong portability.

[0014] 4. The ash and slag blocking component of this utility model can intercept the high-speed, high-energy ash and slag that is ejected back, thereby preventing ash and slag from injuring people or damaging property. At the same time, it can also collect the ash and slag, preventing it from spreading on the working face, thus achieving the goal of inherent safety.

[0015] 5. The main power source of this utility model is the high-pressure air from the existing air compressor, without adding any other power source, which makes it very simple to use. Attached Figure Description

Detailed Implementation

[0017] To further illustrate the technical solution of this utility model, the following embodiments will be used to further explain this utility model.

[0018] like Figure 1 As shown, a horizontal blast hole ash cleaning device includes a high-pressure air pipeline, which comprises a horizontal pipeline 1 and a vertical pipeline 2. The horizontal pipeline 1 includes multiple sets of cut-off pipes 8, with adjacent cut-off pipes 8 connected by threads. One or more baffles 9 are rotatably connected to each cut-off pipe, and the baffles 9 correspond to equidistant gaps. The baffles 9 are evenly distributed on the cut-off pipes 8. Multiple limiting blocks 10 are provided on the horizontal pipeline 1, and each limiting block 10 corresponds one-to-one with a baffle 9. The included angle between the baffle 9 and the horizontal pipeline 1 is set to β, and the range of β is set to 0-30°. °, the transverse pipe 1 and the longitudinal pipe 2 are connected by threads. The transverse pipe is provided with a buckle 3 and the longitudinal pipe 2 is provided with a locking block 4. The buckle 3 and the locking block 4 correspond to each other. The front end of the transverse pipe 1 is located at the innermost part of the horizontal blast hole 5. The transverse pipe 1 is located at the upper part of the horizontal blast hole 5. The lower part of the transverse pipe 1 is provided with equally spaced gaps. The end of the longitudinal pipe 2 is connected to the air outlet of the air compressor through a hose. Ash and slag blocking components 6 are provided at the inlet of the transverse pipe 1 and the horizontal blast hole 5. A pressure regulator 7 is provided in the middle of the longitudinal pipe 2.

[0020] Working steps: First, determine the number of cross-sections 8 to be installed in the transverse pipe 1 based on the length of the horizontal blast hole 5. One or more baffles 9 are installed on each cross-section 8. The transverse pipe 1 is then inserted into the horizontal blast hole 5, and placed in the upper part of the hole. Upon entry, the baffles 9, due to their own weight and the ash residue inside the hole, are in near-parallel contact with the transverse pipe 1. After complete entry, due to the limiting block 10, their own weight, and the ash residue, the angle β between the baffles 9 and the transverse pipe 1 is between 0° and 30°. The transverse pipe 1 and the longitudinal pipe 2 are fixed in direction and position by clips 3 and clips 4. Ash residue blocking components 6 are installed on the transverse pipe 1. Second, the pressure regulator 7 adjusts the pressure of the high-pressure gas in the high-pressure gas pipe 1. Finally, the high-pressure gas in the baffles 9 discharges the ash residue through the ash residue discharge port 11. The first ash residue blocking plate 602 and the second ash residue blocking plate 603 provide safety protection for the workers.
