Description

Technical Field

[0001] The utility model relates to the technical field of concrete spraying machines, in particular to a high-pressure long-distance spraying mechanism and a wet concrete spraying machine. Background Art

[0002] Concrete spraying machines use mechanical transmission to deliver materials to a mixing chamber and an air chamber. After sealing, the materials are blown into a cyclone using high-pressure air. The cyclone introduces high-pressure air, and its special structure forms a multi-head spiral that disperses and accelerates the materials, causing them to rotate and float. The materials then enter the feed pipe and reach the nozzle for spraying. However, the effective spraying distance of existing sprayers is only about 50 meters, while the spraying distance required in mines is 500 meters or even more than 1,000 meters. To meet these requirements, existing sprayers have adopted various methods to increase the sealing degree to increase the spraying distance. Some change the feeding method, while others use hydraulic pressure to increase the sealing. This inevitably increases the size, weight, and complexity of the machines, and the effective distance is difficult to guarantee, which greatly reduces production capacity. Overall, this is only achieved at the source of the machine, and it is also prone to a series of problems such as pipe blockage during the transportation process. Utility Model Content

[0021] The following further elaborates on the technical solution of the present utility model in conjunction with the attached Figure 1-2 ,:

[0022] Embodiment 1

[0023] As Figure 1-2 shown, a high-pressure long-distance injection mechanism includes a cyclone 1. The inlet of the cyclone 1 is provided with a first material conveying pipe 2, and the outlet of the cyclone 1 is provided with a second material conveying pipe 3. And under the limitation of the corresponding fastener 4, the first material conveying pipe 2 and the second material conveying pipe 3 are respectively stably abutted against the inlet and outlet positions of the cyclone 1. That is to say, the first material conveying pipe and the second material conveying pipe are respectively fastened at both ends of the cyclone by fasteners, so that the outlet of the first material conveying pipe and the inlet of the second material conveying pipe are respectively stably abutted against the inlet and outlet positions of the cyclone, so as to quickly output concrete.

[0024] Specifically, as Figure 1 shown, the fastener 4 includes a connecting flange and a connecting sleeve. The connecting sleeve is connected to the flange interface on the cyclone 1 through the connecting flange; that is to say, it is fixedly installed at the port position of the cyclone 1 by using the connecting sleeve and the connecting flange. In this embodiment, the connecting sleeve is a steel sleeve.

[0025] It should be noted that the connecting flange and the connecting sleeve are of an integrally formed structure. That is, to ensure the overall structural strength, the connecting flange and the connecting sleeve are designed as an integral structure.

[0026] The first material conveying pipe 2 and the second material conveying pipe 3 pass through the corresponding connecting sleeves and the connecting flanges and are respectively abutted against the inlet and outlet positions of the cyclone 1. That is to say, the first material conveying pipe and the second material conveying pipe are respectively passed through the connecting sleeves until the ends of the first material conveying pipe and the second material conveying pipe are abutted against the port positions of the cyclone. At this time, the first material conveying pipe and the second material conveying pipe cannot move forward.

[0027] In some embodiments, as Figure 1As shown, the connecting sleeve is provided with a limit hole, through which a wood screw is inserted for securing the first and second feed pipes to their respective connecting sleeves. In other words, once the first and second feed pipes have been inserted into position and cannot be advanced any further, the wood screw on the connecting sleeve is passed through the limit hole to connect the first and second feed pipes, thereby securing the first and second feed pipes to their respective connecting sleeves.

[0028] Specifically, if Figure 1 As shown, the cyclone 1 is connected to a pressurized ventilation device for increasing the air volume and pressure entering the cyclone, thereby increasing the spray distance of concrete flowing through the second feed pipe. Specifically, by connecting the pressurized ventilation device to the cyclone, it introduces high-pressure air into the cyclone. Combined with the cyclone's swirl function, the powerful wind pressure and air volume further disperse, accelerate, rotate, and float the material, allowing it to be transported to greater distances. Multiple devices can be installed in the feed pipe to meet site requirements, with a maximum reach of over 1,000 meters.

[0029] In some embodiments, as Figure 1 and Figure 2 As shown, at least one set of pressurized ventilation components is arranged on the cyclone. That is, one set of pressurized ventilation components can be installed on the cyclone, or two sets of pressurized ventilation components can be installed on the cyclone in a stacked manner, or three sets of pressurized ventilation components can be installed on the cyclone. The specific number of pressurized ventilation components to be installed is selected according to actual conditions.

[0030] Specifically, if Figure 1 and Figure 2 As shown, the pressurized ventilation component includes a ventilation pipe 5, one end of which is connected to the inner cavity of the cyclone 1, and the other end of which is fed with high-pressure air from the mine. A booster pipe 6 is provided on the ventilation pipe 5, which is in communication with the ventilation pipe 6, and the booster pipe 6 is in communication with the air amplifier 7. The inlet of the air amplifier 7 is provided with an air inlet for feeding high-pressure air from the mine. In other words, high-pressure air from the mine is fed into the inner cavity of the cyclone through the ventilation pipe, and high-pressure air is simultaneously fed into the inner cavity of the cyclone through the air amplifier. The cyclone ventilation duct and the air amplifier are simultaneously fed with high-pressure air. Under the action of strong wind pressure and air volume, the materials are blown away, accelerated, rotated, and floated again, and transported to further distances.

[0031] It should be noted that, in this embodiment, an angle is formed between the air inlet and the ventilation duct, the angle range is 0°-90°, and in this embodiment, the angle is 45°.

[0032] Example 2

[0033] A wet concrete spraying machine includes a machine body, wherein the machine body is provided with a concrete spraying chamber and a mixing chamber. The concrete spraying chamber and mixing chamber are connected to a first feed pipe of a high-pressure remote spraying mechanism. In other words, by connecting the high-pressure remote spraying mechanism with the spraying chamber and mixing chamber of the spraying machine, the concrete is pressurized again by the high-pressure remote spraying mechanism after being pressurized by the concrete spraying machine, thereby increasing the concrete spraying distance.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
