[0018] Figure 3 is the structural schematic diagram of the diversion hood of the embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the present utility model in conjunction with the drawings and embodiments:

[0020] Such as Figures 1 to 3As shown in the figure, a pouring device for refractory products of the present utility model includes a pouring hopper 1. A screw conveyor 2 is provided at the bottom outlet of the pouring hopper 1 for transporting refractory materials. An air flow dredging cover 3 is coaxially arranged outside the pouring hopper 1. Since the pouring hopper 1 is of a conical structure, the lower space gradually decreases as the material falls, and the probability of blockage is high. Therefore, the air flow dredging cover 3 is arranged in the middle and lower part of the pouring hopper 1. An air flow chamber 4 is formed inside the air flow dredging cover 3. The air flow chamber 4 is connected to a gas source pipeline 5 in a conducting manner. The gas source pipeline 5 is connected with a pulse valve, and the pulse valve is connected with a buffer tank. The buffer tank is connected to the gas source so as to transport gases with different pressures into the pouring hopper 1 according to requirements to achieve smooth feeding. Ventilation holes 6 that are in communication with the air flow chamber 4 are arranged on the inner side wall of the air flow dredging cover 3. The ventilation holes 6 are in communication with the inside of the pouring hopper 1. During operation, air flows into the pouring hopper 1 through the ventilation holes 6 and acts on the refractory materials to assist the falling of the refractory materials, ensuring the smoothness of the refractory material feeding and guaranteeing the working efficiency.

[0021] Furthermore, a plurality of diversion bins 7 are convexly arranged on the inner side surface of the air flow dredging cover 3. The diversion bins 7 are in communication with the air flow chamber 4, and the ventilation holes 6 are arranged on the diversion bins 7. Installation holes matching the diversion bins 7 are provided on the pouring hopper 1. Both the diversion bins 7 and the air flow dredging cover 3 are made of high-strength steel plates to ensure the structural strength of the pouring hopper 1. The setting of the diversion bins 7 can realize the connection between the air flow dredging cover 3 and the pouring hopper 1 through the installation of the diversion bins 7 in the installation holes, reduce the opening area of the pouring hopper 1, and ensure the structural strength of the pouring hopper 1. Preferably, after the diversion bins 7 are installed into the installation holes, their surfaces are flush with the inner wall of the pouring hopper 1 to avoid hindering the feeding.

[0022] Furthermore, on two adjacent diversion bins 7, a support rod is arranged along the radial direction inside the ventilation hole 6 of one of the diversion bins 7. A guide rod 8 is movably arranged in the middle of the support rod, and a limiting piece 9 is arranged at the end of the guide rod 8. A diversion cover 10 is arranged at the front end of the guide rod 8. The side of the diversion cover 10 located inside the ventilation hole 6 is open, and a limiting plate 11 is arranged on the side located outside the ventilation hole 6. Diversion holes 12 are arranged on the side wall of the diversion cover 10. In the initial state, due to the high temperature and large internal pressure of the refractory materials in the pouring hopper 1, the limiting plate 11 is attached to the corresponding ventilation hole 6. During operation, as air is transported into the air flow dredging cover 3, the limiting plate 11 will be pushed open, driving the guide rod 8 to move axially along the ventilation hole 6. At this time, the diversion cover 10 will move out of the ventilation hole 6, and the diversion holes 12 will move with the diversion cover 10 to the outside of the ventilation hole 6, and air will be blown out from the diversion holes 12 and act on the inner wall of the pouring hopper 1 to clean its inner wall. Inclined diversion slopes are arranged on the diversion covers 10 on both sides of the diversion to provide a guide for the flow direction of the air, so that the air acts on the inner wall of the pouring hopper 1 and at the same time increases the coverage area of the air flow.

[0023] Among them, the diversion bins 7 of the diversion hood 10 are arranged alternately with those of the diversion bins 7 without the diversion hood 10, that is, one of the adjacent two diversion bins 7 is provided with the diversion hood 10 and the other is not; this can avoid the over-dense arrangement of the diversion hoods 10, and when cleaning the inner wall of the pouring hopper 1, the airflows will impact and disturb each other, affecting the normal flow direction of the airflows; at the same time, it also ensures that the airflows used to dredge the materials act evenly on the refractory materials. In addition, in this embodiment, two air chambers 4 are formed and are respectively communicated with different gas source pipes 5; one of the air chambers 4 is communicated with the diversion bin 7 provided with the diversion hood 10; the other air chamber 4 is communicated with the diversion bin 7 without the diversion hood 10. So that the airflows for dredging the materials and the airflows for cleaning the inner wall of the pouring hopper 1 do not interfere with each other, and the two can be carried out separately.

[0024] Furthermore, the corresponding diversion holes 12 on the diversion bin 7 are respectively arranged towards the inner wall of the pouring hopper 1 in different opening directions; preferably, the openings of the diversion holes 12 on the upper diversion hood 10 are arranged upward, the openings of the diversion holes 12 in the middle are arranged towards the left and right sides, and the diversion holes 12 at the lower part are arranged downward; in addition, the diversion holes 12 at the same height face the same direction. The above optimized settings can ensure the coverage area when cleaning the inner wall of the pouring hopper 1 and reduce the interference degree between the airflows. In this embodiment, the vent holes 6 without the diversion hood 10 are arranged obliquely downward so that the airflows can provide a downward thrust to the refractory materials to assist the falling of the refractory materials.

[0025] When the utility model is in use, high-pressure airflows can be regularly or continuously introduced into the pouring hopper 1 through the airflow dredging hood 3 to provide assistance for the falling of the refractory materials with low fluidity, reduce the probability of blockage inside the pouring hopper 1, and ensure the working efficiency; during or after the feeding process, the inner wall of the pouring hopper 1 can also be cleaned by spraying high-pressure airflows through the diversion holes 12 by using the airflow dredging hood 3, avoiding the adhesion and accumulation of materials on the inner wall of the pouring hopper 1, resulting in a narrow internal space of the hopper and blockage; through the delivery of high-pressure airflows into the pouring hopper 1, the utility model can be converted from passive dredging and blocking to active anti-blocking, from treatment to prevention, which not only reduces the labor intensity, greatly ensures the working efficiency, but also effectively reduces the construction cost, reduces the irreversible damage to the pouring hopper 1 caused by active dredging and blocking, and ensures the service life of the pouring hopper 1.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
