Description

Technical Field

[0001] The utility model relates to the technical field of powdered fuel transportation for glass production, and more specifically, to an air pressure powder feeding and filling device which can effectively reduce dust pollution at the filling site. Background Art

[0002] In glass production, petroleum coke powder is needed as the combustion fuel of the furnace. Petroleum coke powder is usually stored in the fuel bunker. Sometimes it needs to be transported to other workshops in the factory. It is usually transported by tanker trucks. The petroleum coke powder is first transported to the filling tank by a bucket elevator. Then, using gravity, the valve is opened to allow the petroleum coke powder to flow to the filling pipe. Then, it is injected into the storage tank of the tanker truck from the filling pipe. However, due to the poor fluidity of petroleum coke powder and its slow flow rate, it often clumps on the inner wall of the filling tank. Workers need to use hammering tools to knock on the outer wall of the filling tank to loosen the powder to avoid blockage. The filling speed is slow, which seriously affects work efficiency.

The negative pressure powder suction pipe 3 can be sealed and connected to the tank discharge port of the transport tank truck to prevent powder leakage and dust pollution.

[0035] The utility model can effectively reduce the dust pollution at the filling site by using an air pressure feeding powder filling device. An air-leveling box 7 is provided on the outer wall of the conical funnel 5 at the bottom of the filling tank 4. High-pressure gas is input into the air-leveling box 7 through the air compressor 9. The high-pressure gas is sprayed into the tank body from the air jet hole 8 between the air-leveling box 7 and the conical funnel 5. The petroleum coke powder in the filling tank 4 can flow rapidly under the drive of the air flow and be injected into the tank body of the transport tank truck under the filling platform 1 from the powder outlet pipe 6 and the filling pipe 2. The injection speed is fast, which improves the filling efficiency. A negative pressure powder suction pipe 3 connected with the negative pressure device 11 is provided on the filling platform 1, and the inlet of the negative pressure powder suction pipe 3 is extended into the tank body feed port of the transport tank truck. The air flow and dust generated in the tank body can be sucked away to avoid dust overflowing to the outside of the tank body to cause air pollution. The air pressure inside the tank body can also be reduced, thereby improving the speed of injecting petroleum coke powder.

[0036] In this embodiment, two uniform air nets 13 are provided in the uniform air box 7, and the two uniform air nets 13 are provided with an array of uniform air holes. The uniform air nets 13 provided in the uniform air box 7 can stabilize the input high-pressure air flow so that the air flow can flow evenly from the air jet holes 8 into the filling tank 4.

[0037] In this embodiment, a breathable base cloth 15 is clamped between the two air-uniform nets 13 . The breathable base cloth 15 has an isolation function to prevent the petroleum coke powder in the filling tank 4 from entering the air supply pipe 10 .

[0038] In this embodiment, the inner wall of the air uniforming box 7 is provided with a positioning protrusion 16, and the two air uniforming nets 13 are fixedly mounted on the positioning protrusion 16 by a bolt structure. The air uniforming net 13 and the breathable base cloth 15 can be quickly fixed by the bolt structure, which also facilitates the replacement of the air uniforming net 13 and the breathable base cloth 15.

The heating temperature is 40 - 60 °C. After the heated air flow enters the inside of the filling tank 4, it can appropriately heat the petroleum coke powder, reduce the adhesiveness of the petroleum coke powder, and improve the fluidity of the petroleum coke powder.

[0040] In this embodiment, the filling pipe 2 and the negative pressure powder suction pipe 3 are steel wire hoses. They are transported through the steel wire hoses, have good wear resistance and long service life.

The vacuum pump 18 evacuates to form a negative pressure in the dust storage tank 17, and then the negative pressure pipe 12 and the negative pressure powder suction pipe 3 have suction force to suck the dust into the dust storage tank 17.

[0042] In this embodiment, three air distribution boxes 7 are evenly arranged on the outer wall of the conical funnel 5. The height positions of the three air distribution boxes 7 are adapted to the height position of the powder outlet pipe 6. The powder outlet pipe 6 is arranged on the outer wall of the conical funnel 5 to increase the height of the powder outlet. Because the height of the tank body of the transport tanker is relatively high, powder cannot be unloaded from the discharge port at the bottom of the conical funnel 5;

[0043] The heights of the three air distribution boxes 7 are the same as the height of the powder outlet pipe 6, which is convenient for the high-pressure gas to blow the petroleum coke powder at the inlet of the powder outlet pipe 6 into the powder outlet pipe 6.

The difference is that, as shown in the attached Figure 6As shown in the figure, a bucket elevator 21 is provided on one side of the filling tank 4. A feeding hopper 22 communicating with the filling tank 4 is provided at the top of the bucket elevator 21. The bucket elevator 21 is used to transport the petroleum coke powder in the warehouse into the filling tank 4. The top end of the bucket elevator 21 is communicated with the air extraction pipe 19 through a pipeline. The negative pressure pipe 12 is connected to the middle part of the housing of the bucket elevator 21. The negative pressure powder suction pipe 3 is communicated with the negative pressure pipe 12. In this embodiment, the dust extracted from the discharge port of the tank body of the transport tanker by the negative pressure powder suction pipe 3 can be transported into the bucket elevator 21. The dust settles inside the bucket elevator 21 and can be transported into the filling tank 4 along with the buckets of the bucket elevator 21 for continuous filling.

[0047] Working principle:

[0048] An air distribution box 7 is arranged on the outer wall of the conical funnel 5 at the bottom of the filling tank 4. High-pressure gas is input into the air distribution box 7 through an air compressor 9. The high-pressure gas is sprayed into the tank body through the air injection holes 8 between the air distribution box 7 and the conical funnel 5. The petroleum coke powder in the filling tank 4 can flow quickly under the drive of the air flow and is injected into the tank body of the transport tanker below the filling platform 1 through the powder discharge pipe 6 and the filling pipe 2. The injection speed is fast, improving the filling efficiency. A negative pressure powder suction pipe 3 connected to the negative pressure device 11 is arranged on the filling platform 1. The inlet of the negative pressure powder suction pipe 3 is extended into the inlet of the tank body of the transport tanker, so that the air flow and dust generated in the tank body can be sucked away, avoiding the dust from overflowing outside the tank body and causing air pollution, and reducing the air pressure inside the tank body, increasing the injection speed of the petroleum coke powder, and avoiding the generation of dust pollution to the environment. During the work, the loading equipment runs stably each time, with high efficiency. About 32 tons of petroleum coke powder can be loaded in about 45 minutes, and the operation is simple, with almost no dust pollution to the environment.

[0049] The above is only the preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
