Technical Field

[0001] The utility model belongs to the technical field of powder material feeding, and in particular relates to a powder material anti-caking hopper. Background Art

[0002] The lower hopper is a device that transfers materials from one container to another, and is often used to transport granular or powdered materials. The lower hopper generally includes an upper barrel section and a lower conical section. The upper end of the barrel section can be connected to a conveying pipeline, and the lower end of the conical section can be connected to a packaging bag, a packaging box, a conveyor belt or other containers, thereby realizing the transportation and protection of materials.

[0003] Steel slag is a kind of waste residue produced in the steelmaking process. Steel slag powder refers to the material that is ground into powder. When steel slag is subjected to CO2 mineralization, it needs to be crushed and strengthened to fully dissolve the calcium element in the steel slag. At present, steel slag powder may easily clump during the feeding process due to factors such as the humid surrounding environment, thereby blocking the feeding port and affecting the feeding efficiency of the powder.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a powder anti-caking hopper.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

An auxiliary heating cavity is formed between the heating outer frame 202 and the unloading funnel 201, and a heating rod 203 is installed in the auxiliary heating cavity. Preferably, the heating rod 203 is an intelligent control type, so that the staff can control the temperature of the heating rod 203, which is convenient for the staff to control the temperature of the air blown into the powder, and prevent the excessive temperature from affecting the powder.

[0028] like Figure 1-Figure 2 As shown, a plurality of crushing plates 208 are fixed on the inner wall of the discharge hopper 201, which are used to cooperate with the rotating plate 302 to crush the agglomerated powder materials, so that the powder materials are not easy to agglomerate.

[0029] like Figure 1 As shown, a lower connecting pipe 211 is fixedly connected between the feeding hopper 201 and the processing box 1, which is used to convey the powder downward, so that the powder is not easy to spill, and the sealing of the device is improved. A filter screen 212 is installed in the lower connecting pipe 211, which is used to screen the powder, so that the agglomerated powder is not easy to fall directly into the processing box 1.

[0030] Specifically, a plowshare 213 is installed at one end of the main rotating shaft 301 close to the filter screen 212 for scraping the filter screen 212 to crush the lumps on the surface of the filter screen 212, thereby improving the crushing effect on the powder and reducing the probability of blockage.

[0031] like Figure 1-Figure 3As shown, a pair of air pumps 204 are provided on the outside of the heating outer frame 202, which are used to draw in gas and provide power for gas transportation. A delivery air pipe 205 is fixedly connected to the air pump 204, and the other end of the delivery air pipe 205 is connected to the auxiliary heating chamber and is used to transport gas so that the gas can enter the auxiliary heating chamber. A drying box 214 is provided below the air pump 204, which is used to dry the inhaled gas so that the gas is not easy to bring moisture into the powder, thereby improving the drying effect of the powder. The drying box 214 is fixed on the heating outer frame 202, so that the drying box 214 is not easy to fall off, and the fixing effect is improved. A connecting pipe 215 is fixedly connected between the drying box 214 and the air pump 204, which is used for the flow of gas, so that the dried gas can be extracted and then transported to the heating outer frame 202 through the delivery air pipe 205.

[0032] Among them, a pair of air pumps 204 and the heating frame 202 are fixedly connected with support pads 206 for fixing the air pumps 204 to support the air pumps 204, so that the air pumps 204 are not prone to shaking or tilting, thereby improving the stability of the device.

[0033] like Figure 1-Figure 2 As shown, a plurality of air holes 207 are drilled on the discharge funnel 201 to assist the gas in the heating chamber to enter the conveying air chamber 209, so that it can be ejected through a plurality of one-way valves 210, and the gas can be heated by the heating rod 203, so that the moisture on the powder can be evaporated quickly, thereby making it less likely for the powder to clump.

[0034] like Figure 1-Figure 2 As shown, multiple crushing plates 208 are each provided with a conveying air cavity 209 for conveying air, so that the gas can be ejected from multiple one-way valves 210. Multiple one-way valves 210 are installed on the side walls of the conveying air cavity 209 for ejecting gas outward, so as to heat the powder conveniently, thereby improving the evaporation efficiency of the powder water and making it difficult for the powder to flow back. Furthermore, the one-way valve 210 can also impact the powder on the filter screen 212, so that the powder is not easy to clump, thereby improving the crushing effect of the powder.

[0035] like Figure 1-Figure 3 As shown, the rotary crushing mechanism 3 is installed on the discharge funnel 201, and the rotary crushing mechanism 3 includes a main rotating shaft 301, which is used to support multiple rotating plates 302 and drive the multiple rotating plates 302 to rotate. Multiple rotating plates 302 are installed on the main rotating shaft 301, and the multiple rotating plates 302 and the multiple crushing plates 208 are staggered with each other, and are used to cooperate with the crushing plates 208 to crush the powder, so that the powder is not easy to clump.

[0036] like Figure 1-Figure 3As shown, one end of the main rotating shaft 301 is fixedly connected to a driving motor 303, which is used to drive the rotation of the main rotating shaft 301 to provide power to prevent the powder from agglomerating and to crush the agglomerated powder.

A plurality of fixing rods 305 are fixedly connected between the fixing sleeve 304 and the heating outer frame 202 to play a supporting role.

[0037] When in use, a pair of air pumps 204 are started to draw in external air, which is then transported to the auxiliary heating chamber through the air delivery pipe 205, and then transported to the air delivery chamber 209 through the air vents 207, and then ejected out through a plurality of one-way valves 210;

[0038] The air transported into the auxiliary heating chamber is heated by the heating rod 203 to increase the air temperature, so that the powder can be heated after the one-way valve 210 is sprayed out, thereby increasing the evaporation of moisture, and by starting the driving motor 303, the main rotating shaft 301 drives the multiple rotating plates 302 to rotate, and then the powder is not easily agglomerated through the crushing of the multiple rotating plates 302 and the multiple crushing plates 208. Finally, the powder is screened by the filter screen 212 and falls into the processing box 1.
