[0002] Material conveying is an essential part of material processing and production. Material conveying is widely used in multiple industries. For the conveying of bulk materials, screening is generally required and belt conveying is more commonly used, such as high-temperature ores and slag in the metallurgical and mining industries, coal and coke in the coke industry, aluminum and foundry materials in the foundry industry, etc.

[0003] For some of the above-mentioned materials, their temperature is generally relatively high after processing. Currently, the common conveying method is to directly convey the processed materials through conveying equipment for natural cooling. However, there are certain defects. For some ores or coke, etc., there will inevitably be many granular slag after cooling. On the one hand, it may cause environmental pollution during the conveying process. On the other hand, over time, the slag and dust accumulate on the conveying equipment for a long time, affecting the conveying. Summary of the Invention

[0014] To better remove residues, preferably, a vibrating screen is slidably connected to the discharge box through a second vibrating spring, and the vibrating screen is located below the guiding cone cylinder.

[0015] To facilitate the downward pushing of the vibrating screen, further, an inclined ring is fixedly connected to the vibrating screen. When the guiding cone cylinder moves downward to push the vibrating screen, the inclined ring abuts against the inner side wall of the guiding cone cylinder.

[0016] To guide the lifting of the guiding cone cylinder, preferably, a first cylinder column is fixedly connected to the discharge box, a second cylinder column is slidably connected to the first cylinder column, the upper end of the second cylinder column is fixedly connected to the guiding cone cylinder, the cooling cold air pipe is communicated with the second cylinder column, and a cold air inlet pipe is fixedly connected to the discharge box, and the cold air inlet pipe is communicated with the first cylinder column and the second cylinder column.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Embodiment 1:

[0030] Reference Figure 1 and Figure 2 A feeder intelligent industrial bulk material production system includes a feed box 1, a conveyor belt 2 and a vibrating screening disk 3. The feed end of the conveyor belt 2 is located at the outlet of the feed box 1, and the discharge end of the conveyor belt 2 is located above the vibrating screening disk 3. The lower end of the feed box 1 is connected to a discharge box 4, and a discharge hole 402 is provided on the discharge box 4. The conveyor belt 2 adopts chain conveying, and the bulk material coming out of the discharge hole 402 is transported to the vibrating screening disk 3 through the conveyor belt 2 for screening.

[0031] Reference Figure 3 and Figure 4 A feeding through hole is provided in the feeding box 1, and a guiding cone 5 is slidably connected in the feeding through hole. A discharging box 4 is fixedly connected to the bottom of the feeding box 1, and the inner diameter of the discharging box 4 is larger than the outer diameter of the lower end of the guiding cone 5.

[0032] A conical guide cone 5 is used, and the tip of the guide cone 5 is located at the feed port. The incoming material falls along the outer wall of the guide cone 5 to the surroundings of the guide cone 5. The guide cone 5 is intermittently raised and lowered. When the lower end of the guide cone 5 descends and enters the discharge box 5, the bulk material falls through the gap between the guide cone 5 and the discharge box 4.

[0033] Reference Figure 5 and Figure 6 A cooling air pipe 10 is fixedly connected to the inner wall of the guide cone 5, and a plurality of sliding holes 501 are provided on the guide cone 5. The sliding holes 501 are connected to the cooling air pipe 10 through the connecting holes 502. A cooling column 11 is slidingly and sealingly connected in the sliding holes 501, and a cooling air channel 1101 is provided on the cooling column 11. By delivering cold air to the cooling air pipe 10, the cooling air pipe 10 is located on the inner wall of the guide cone 5, and the low temperature state of the guide cone 5 is maintained, so that the bulk material in the feed box 1 is quickly cooled. A cooling column 11 is telescopically arranged on the outer guide cone 5, and the cooling can enter the cooling channel of the cooling column 11 through the cooling cold air pipe 10, the connecting hole 502 and the sliding hole 501, thereby ensuring the low temperature state of the cooling column 11. During the process of the bulk material being guided and falling, it collides with the cooling column 11 to achieve cooling of the material, and at the same time, small particles on the surface of the material can be separated from the material. In addition, the cooling column 11 can be telescopically extended in the sliding hole 501 to pound the material, and the residue formed on the surface of the coke or ore after cooling can be separated.

[0034] Reference Figure 7, an air extraction pipe 101 is connected to the feeding box 1. A first air extraction hole 102 is provided on the feeding box 1, and a second air extraction hole 103 is provided on the discharging box 4. Both the first air extraction hole 102 and the second air extraction hole 103 are communicated with the air extraction pipe 101. For the falling dust and residues, a powerful external suction pump can be used through the air extraction pipe 101, and the small particle residues and dust can be sucked away through the first air extraction hole 102 and the second air extraction hole 103, avoiding accumulation on conveying equipment such as the conveyor belt 1.

[0035] Refer to Figure 5 and Figure 6 , in specific implementation, in order to further improve the cooling effect, a cone head 1102 is provided at the top of the cooling column 11. A first exhaust channel 1103 is provided on the cone head 1102, and a dispersed cooling air hole 1104 with a pressure relief valve is provided on the cooling column 11. The first exhaust channel 1103 is communicated with the dispersed cooling air hole 1104. By conveying cold air into the sliding hole 501, the internal pressure of the sliding hole 501 increases and pushes the cooling column 11 outwards. When the pressure threshold of the pressure relief valve is reached, the dispersed cooling hole 1104 opens, and the gas is discharged through the first exhaust channel 1103 to further cool the feeding box. A tension spring 12 is rotatably connected to the bottom of the sliding hole 501, and the other end of the tension spring 12 is connected to the cooling column 11. Through the pulling effect of the tension spring 12, the cooling column 11 is reset at the same time.

[0036] Refer to Figure 6 , during the actual production process, it should be noted that in order to further improve the cooling effect, a cooling rod 17 is connected to the top of the cooling column 11. A second exhaust channel 1701 is provided on the cooling rod 17. The second exhaust channel 1701 is communicated with the dispersed cooling air hole 1104. The blowing end of the second exhaust channel 1701 faces the surface of the guiding cone 5, and the cold air directly blows on the surface of the guiding cone 5 to further improve the cooling effect.

[0037] Refer to Figure 5 and Figure 6 , in some other implementation manners, a vibrating cone piece 15 is covered on the cone head 1102. A first vibrating spring 16 is connected between the vibrating cone piece 15 and the cone head 1102. The vibrating cone piece 15 covers the air outlet end of the first exhaust channel 1103. A large amount of gas can be quickly ejected by the opening of the pressure relief valve, which can blow the vibrating cone piece 15 to vibrate, and can further facilitate the removal of residues on the surface of the material.

[0038] Refer to Figure 5 and Figure 6, when implemented specifically, in order to further improve the effect of removing residues on the surface of the material, the cooling column 11 can rotate when it expands and contracts. The bottom of the sliding hole 501 is rotatably connected to a tension spring 12. The tension spring 12 is rotatably connected to the rotating ring on the sliding hole 501, and the tension spring 12 is fixed on the rotating ring, so that the tension spring 12 is rotatably connected to the sliding hole 501. The other end of the tension spring 12 is connected to the cooling column 11. A spiral column 13 is fixedly connected to the bottom wall of the sliding hole 501 through a bracket. A spiral hole 14 matching the spiral column 13 is provided on the cooling column 11. When expanding and contracting, under the action of the spiral column 13 and the spiral hole 14, the cooling column 11 can rotate.

[0039] Embodiment 2:

[0040] Referring to Figure 1 and Figure 2 , an intelligent industrial bulk material production system for a feeder is basically the same as that in Embodiment 1. The difference is that a vibrating screen 6 is slidably connected to the discharge box 4 through a second vibration spring 602. The vibrating screen 6 is located below the guiding conical cylinder 5. A feed pipe 18 with a ball valve is fixedly connected to the feed inlet of the feed box 1.

[0041] In order to further effectively remove particles and impurities, when the guiding conical cylinder 5 moves to the discharge box 4, the vibrating effect of the vibrating screen 6 is used to lift the particles, facilitating the adsorption of particle impurities.

[0042] Referring to Figure 4 , an inclined ring 601 is fixedly connected to the vibrating screen 6. When the guiding conical cylinder 5 moves downward to push the vibrating screen 6, the inclined ring 601 abuts against the inner side wall of the guiding conical cylinder 5, which can ensure that the guiding conical cylinder 5 abuts against the vibrating screen 6.

[0043] Referring to Figure 4 and Figure 7 , in order to realize the lifting of the guiding conical cylinder 5, the following technical solution is adopted. A first cylinder column 7 is fixedly connected to the discharge box 4. A second cylinder column 8 is slidably connected to the first cylinder column 7. The upper end of the second cylinder column 8 is fixedly connected to the guiding conical cylinder 5. The cooling cold air pipe 10 is communicated with the second cylinder column 8. A cold air inlet pipe 401 is fixedly connected to the discharge box 4. The cold air inlet pipe 401 is communicated with the first cylinder column 7 and the second cylinder column 8; A return spring 9 is connected between the first cylinder column 7 and the second cylinder column 8.

[0044] It should be noted that in this implementation method, the following steps are specifically adopted for operation. Step 1: Add materials intermittently and once through the feed pipe 18, and then close the feed pipe. In the initial state, under the supporting action of the return spring 9, at this time, the guiding conical cylinder 5 will not enter the discharge box 4;

[0045] Step 2: Continuously introduce cold air during the process of Step 1. When the pressure threshold of the pressure relief valve is reached, the dispersion cooling holes 1104 open, and a large amount of cooling air instantaneously enters the feed box 1. Under the action of the pressure, the guiding cone 5 quickly moves downward;

[0046] Step 3: The guiding cone 5 enters the discharge box 4 and presses down the vibrating screen 6. At this time, the bulk material falls through the gap between the guiding cone 5 and the discharge box 4. At the same time, turn on the external air extraction pump to extract air through the first air extraction hole 102 and the second air extraction hole 102 to achieve the extraction of the reference.

[0047] Step 4: The guiding cone 5 quickly rises and returns to its original position under the action of the return spring 9. At this time, the vibrating screen 6 vibrates, which helps to extract the residue.

[0048] As described above, only the specific preferred embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
