Description

Technical Field

[0001] The utility model relates to the technical field of slag powder transportation, in particular to automatic slag powder transportation equipment. Background Art

[0002] Slag powder is the abbreviation of granulated blast furnace slag powder. It is a high-quality concrete admixture. It is made from granulated blast furnace slag that meets the GB / T203 standard. It is dried and ground to achieve a powder with a certain fineness and a certain activity index. After the slag is crushed, conveying equipment is required to transport the slag powder.

[0003] Current automatic slag powder conveying equipment, such as the air conveying chute for processing granulated blast furnace slag powder proposed in publication number: CN220536935U, uses a knocking component to enable the knocking head to knock on the material on the gas distributor, causing the gas distributor to vibrate greatly until the slag powder mass is separated from the gas distributor. This can effectively improve the distribution and fluidity of the slag powder mass and avoid affecting the air permeability of the gas distributor. At the same time, the structure of the second spring and the first U-shaped frame can provide a certain buffering and stabilizing effect to ensure the stability and accuracy of the knocking process.

[0004] Some slag powder with high humidity is easy to adhere to the inside of the conveying pipe wall. The existing technology is to set a knocking component to vibrate the conveying pipe by knocking, so as to loosen the attached slag powder and prevent it from adhering to the conveying pipe wall. However, this knocking method has weak cleaning power for the slag powder attached to the conveying pipe wall and cannot effectively clean the slag powder attached to the conveying pipe wall. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic slag powder conveying device, which can effectively clean the slag powder attached to the inner wall of the conveying pipe, improve the cleaning force, and effectively prevent the slag powder from adhering to the inner wall of the conveying pipe.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: an automatic slag powder conveying device, comprising a conveying pipe, wherein the conveying pipe is rotatably connected to a rotating pipe, and the outer side of the rotating pipe is equidistantly connected to a nozzle, wherein:

[0007] A sealing cover is installed in the middle of the inner side of the delivery pipe, the top of the sealing cover is connected to the air inlet pipe, and pipe grooves are passed through both sides of the sealing cover, and the rotating pipe passes through the interior of the sealing cover through the pipe grooves;

[0008] An air inlet is provided on the outer side of the rotating tube located in the sealing cover. A turbine is provided in the air inlet tube. When the turbine rotates, the rotating tube is driven to rotate through a transmission mechanism.

[0009] Preferably, the nozzles are arranged at an angle, and the directions of the nozzles are the same.

[0010] Preferably, a dynamic sealing ring is installed in the tube groove, and the outer wall of the rotating tube is sealedly connected to the inner wall of the tube groove through the dynamic sealing ring.

[0011] Preferably, the transmission mechanism includes a rotating shaft, the internal rotation of the air inlet pipe near the bottom end is connected to the rotating shaft, the top of the rotating shaft is fixedly connected to the turbine, the end of the rotating shaft near the rotating tube is fixedly connected to the first reversing gear, and the rotating tube is fixedly connected to the outer diameter of the first reversing gear corresponding to the first reversing gear.

[0012] Preferably, the first reversing gear and the second reversing gear are perpendicular to each other, and the first reversing gear and the second reversing gear are meshed with each other.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model transmits high-pressure air to the rotating tube through the sealing cover and the air inlet, so that the airflow is ejected from the nozzle. The nozzle is arranged obliquely, so that the airflow flows in the conveying tube, thereby driving the slag powder to flow in the conveying tube. The airflow drives the turbine to rotate when passing through the turbine, and the turbine drives the rotating tube to rotate through the transmission mechanism, so that the rotating tube drives the nozzle to rotate, and the gas ejected from the nozzle can evenly impact the inner wall of the conveying tube, which can effectively clean the slag powder attached to the inner wall of the conveying tube, improve the cleaning force, and effectively prevent the slag powder from adhering to the inner wall of the conveying tube.

[0015] In the utility model, when the high-pressure airflow passes through the turbine, it drives the turbine to rotate. The turbine rotates through the rotating shaft, so that the rotating shaft drives the first reversing gear to rotate. The first reversing gear drives the second reversing gear to rotate through engagement, and then drives the rotating tube to rotate. Through the transmission mechanism, the airflow can automatically drive the rotating tube to rotate when it flows, so that the airflow ejected from the nozzle can evenly impact the inner wall of the delivery pipe, avoiding the formation of dead angles.

[0024] The air inlet pipe 5 transports high-pressure air into the rotating tube 2 through the sealing cover 4 and the air inlet 8, so that the air flow is ejected from the nozzle 3. The nozzle 3 is arranged obliquely, so that the air flow flows in the conveying pipe 1, thereby driving the slag powder to flow in the conveying pipe 1.
