Description

Technical Field

[0001] This utility model relates to a gasification unblocking device for a powder material storage silo, belonging to the field of powder material storage unblocking technology. Background Technology

[0002] Our company's warehouse cleaning machine can be installed and cleaned without human intervention, featuring fast cleaning speed and a safe cleaning process. However, if the discharge port or pressure-reducing cone outlet is blocked, or if there is a gap in the middle without any openings, it will inevitably affect the normal operation of the cleaning machine. Therefore, if the outlet is blocked or there is a gap in the middle during the initial cleaning stage or process, it is necessary to clear the blockage.

[0003] Utility model patent ZL202021225059.8 discloses a gasification and unblocking device for the top of a powdery material silo. The device includes a winch on the silo top, an opening approximately 200mm in diameter on the silo top, and an air inlet for an air compressor or high-pressure air station. Inside the silo is a 159*1400mm diameter steel pipe (filled with iron filings and serving as a venting pipe). The pipe end is fitted with a 300mm long, 1:2 tapered steel body, through which high-pressure air is circulated. Utilizing the weight of the tapered steel body and the high-pressure gas, the powder near the outlet is gasified and discharged. This device largely solves problems such as silo sticking, clogging, and core removal in powdery material silos. However, it has drawbacks such as the light weight of the steel body, the ease with which the unblocking pipe can change direction, and difficulty in controlling the unblocking location. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gasification unblocking device that can effectively solve the problem of blockage at the discharge port of powder storage silo or the discharge port of pressure reducing cone, or the inability to discharge material in the middle of the silo without holes.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a gasification unblocking device for a powder material storage silo, comprising an unblocking winch, an A-frame, an unblocking pipe, an air pipe, and a conical steel body. The unblocking winch and the A-frame are installed on the top of the powder silo. A pulley is fixed on the A-frame. The wire rope of the unblocking winch passes around the pulley and is connected to the upper end of the unblocking pipe. The lower end of the unblocking pipe is connected to the conical steel body. An exhaust hole is opened on the conical steel body. An inlet is opened on the top of the powder silo. The unblocking pipe is vertically downward and passes through the inlet into the powder silo.

[0006] The unblocking pipe contains an air tube. The upper end of the air tube is connected to the air inlet of the air compressor, and the lower end of the air tube is connected to the exhaust hole on the conical steel body.

[0007] The powder silo has a discharge port at the bottom, and the unclogging pipe is located above the discharge port.

[0008] Preferably, the unblocking pipe is composed of multiple unblocking branch pipes connected together.

[0009] Preferably, the upper end of the unblocking manifold is an internally threaded female end and the lower end is an externally threaded male end. A radial through hole is opened in the upper part of the unblocking manifold as a support position, and a radial through hole is opened in the middle part of the unblocking manifold as a rotation position.

[0010] Preferably, the length of the unblocking branch pipe is 1-3m.

[0011] Preferably, the lower part of the conical steel body is a cone with the tip pointing downwards, and the upper part is a cylinder connected to the unblocking pipe by threads. The vent hole vertically penetrates the conical steel body to connect the unblocking pipe and the external space.

[0012] Preferably, the vent is connected to a quick connector via an internal threaded connector, and the lower end of the air tube is connected to the quick connector.

[0013] Preferably, the lower part of the unblocking pipe is fitted with a flow guide, which is shaped like a date pit and located above the conical steel body.

[0014] Preferably, the present invention also includes a pressure-reducing cone, which is a hollow cone with an open bottom, covering the material outlet. The lower part of the pressure-reducing cone has multiple pressure-reducing cone outlets, and the unblocking pipe is located above the outer side of one of the pressure-reducing cone outlets.

[0015] Preferably, the present invention also includes a cleaning machine scraper and a cleaning machine winch. Multiple cleaning machines are evenly distributed on the top edge of the powder silo, and multiple cleaning machines are connected to the cleaning machine scraper through cleaning wire ropes. The cleaning machine scraper is located inside the powder silo.

[0016] Compared with the prior art, the present invention has the following beneficial effects.

[0017] 1. The unblocking pipe in this utility model is easy to position. After the position is accurately found on the top of the silo, the unblocking pipe descends vertically by gravity during the operation of the unblocking winch, and it is not easy to change direction, so the unblocking position is accurate.

[0018] 2. In this utility model, the quick connector for the air pipe is connected to the conical steel body and is stored together with the unblocking pipe, making the air pipe easier to control.

[0019] 3. In this utility model, for overhead powder, a guide is set at the lower part of the unblocking pipe. After the conical steel body penetrates the powder, the powder will collapse into the overhead area, and a large hole can be formed around the unblocking pipe, so that the scraper of the cleaning machine can continue to carry out the cleaning operation normally.

[0020] 4. Equipped with this utility model, the warehouse cleaning machine can be applied to a wider range of applications, suitable for cleaning various materials, reducing or eliminating personnel injuries and disruptions to normal production time caused by manual warehouse cleaning, and is conducive to expanding the warehouse cleaning machine market.

[0031] The present invention provides the following embodiments.

[0032] Example 1

[0033] like Figure 1 , Figure 2 As shown, this utility model discloses a gasification unblocking device for a powder material storage silo, including an unblocking winch 1, an A-frame 2, an unblocking pipe 3, an air pipe 4, and a conical steel body 5. The unblocking winch 1 and the A-frame 2 are installed on the top of the powder silo 6. A pulley is fixed on the A-frame 2. The wire rope of the unblocking winch 1 passes around the pulley and is connected to the upper end of the unblocking pipe 3. The lower end of the unblocking pipe 3 is connected to the conical steel body 5. An exhaust hole 7 is opened on the conical steel body 5. An inlet 8 is opened on the top of the powder silo 6. The unblocking pipe 3 is vertically downward and passes through the inlet 8 to enter the powder silo 6.

[0034] The unblocking pipe 3 is fitted with an air pipe 4. The upper end of the air pipe 4 is connected to the air inlet of the air compressor, and the lower end of the air pipe 4 is connected to the exhaust hole 7 on the conical steel body 5.

[0035] The bottom of the powder storage 6 has a discharge port 9, and the unblocking pipe 3 is located above the discharge port 9.

[0036] The trachea 4 is a flexible tube.

[0037] The inlet 8 is located directly below the pulley on the A-frame 2. In addition, the diameter of the inlet 8 can be 200-350mm.

[0038] The unblocking pipe 3 is composed of multiple unblocking branch pipes 10 connected together.

[0039] like Figure 3 As shown, the upper end of the unblocking manifold 10 is an internally threaded female end and the lower end is an externally threaded male end. The upper part of the unblocking manifold 10 has a radial through hole as a support hole 11, and the middle part of the unblocking manifold 10 has a radial through hole as a rotation hole 12.

[0040] The length of the unblocking branch pipe 10 is 1-3m.

[0041] To facilitate the connection of each unblocking branch pipe 10 and its placement into the powder silo 6, the height of the A-frame 2 should be greater than the length of the unblocking branch pipe 10.

[0042] like Figure 4 As shown, the lower part of the conical steel body 5 is a cone with the tip pointing downwards, and the upper part is a cylinder connected to the unblocking pipe 3 by threads. The vent hole 7 vertically penetrates the conical steel body 5 to connect the unblocking pipe 3 and the external space.

[0043] The exhaust port 7 is connected to the quick connector 15 via the internal thread connector 14, and the lower end of the air tube 4 is connected to the quick connector 15.

[0044] like Figure 1 , Figure 2 As shown, this utility model also includes a pressure-reducing cone 16, which is a hollow cone with an open bottom, covering the material outlet 9. The lower part of the pressure-reducing cone 16 has multiple pressure-reducing cone outlets 17, and the unblocking pipe 3 is located above the outside of one of the pressure-reducing cone outlets 17.

[0045] This utility model also includes a silo cleaning machine scraper 18 and a silo cleaning winch 19. Multiple silo cleaning winches 19 are evenly distributed along the top edge of the powder silo 6. All silo cleaning winches 19 are connected to the silo cleaning machine scraper 18 via silo cleaning wire ropes 20. The silo cleaning machine scraper 18 is located inside the powder silo 6. The specific structure of the silo cleaning machine scraper 18 and the silo cleaning winch 19 is prior art; please refer to our company's patent number ZL201821306620.8, entitled "A Utility Model Patent for a Flat-Top Silo with Armless Silo Cleaning Machine for Powder and Granular Materials."

[0046] The unblocking process in this first embodiment is as follows.

[0047] like Figure 1 As shown, when the powder material condenses at the bottom of the powder silo 6, causing the discharge port 9 to discharge, the powder silo 6 needs to be cleared of blockages.

[0048] First, connect one end of the air pipe 4 to the internal threaded connector inside the conical steel body 5 via the quick connector 15. Then, connect the conical steel body 5 to the lower end of the first unblocking branch pipe 10. Next, use the unblocking winch 1 to lower the conical steel body 5 and the unblocking branch pipe 10 connected to it into the powder silo 6 through the inlet 8. The upper part is supported outside the inlet 8 through the support hole 11. Use the unblocking winch 1 to lift the other unblocking branch pipe 10 and connect it to the first unblocking branch pipe 10. After the connection is made, lower it into the powder silo 6. Continue in this manner to slowly lower the conical steel body 5. Before the conical steel body 5 enters the powder, open the high-pressure air valve to blow air into the air pipe 4. High-pressure air is introduced and sprayed downwards from the exhaust port 7 of the conical steel body 5. The unblocking pipe 3 continues to descend. When the conical steel body 5 is inserted into the powder, the powder is vaporized under the action of gravity and high-pressure air in the unblocking pipe 3, and gradually becomes fluidized. The unblocking pipe 3 continues to descend until it reaches the bottom discharge port 9 or the outlet 17 of the pressure reducing cone at the bottom of the powder silo 6, vaporizing the powder near the discharge port 9 or the outlet 17. At this time, the supply of high-pressure air can be increased until the discharge port 9 or the outlet 17 of the pressure reducing cone is opened, achieving the purpose of unblocking. Then the unblocking pipe 3 is pulled out, and the silo cleaning winch 19 and the silo cleaning scraper 18 work to carry out the silo cleaning operation.

[0049] During the above-mentioned unblocking process, the working position of the conical steel body 5 can be determined by the tension of the wire rope of the unblocking winch 1 or the length of the unblocking pipe 3.

[0050] Example 2

[0051] like Figure 5 , Figure 6 As shown, in the gasification unblocking device for a powdered material storage silo of this utility model, a flow guide 13 is fitted at the lower part of the unblocking pipe 3. The flow guide 13 is shaped like a date pit and is located above the conical steel body 5. In order to effectively unblock, the distance between the flow guide 13 and the conical steel body 5 is 300mm to 1500mm. The rest of the structure is the same as in Embodiment 1.

[0052] The unblocking process in this second embodiment is as follows.

[0053] like Figure 5 As shown, when the powder material is suspended in the middle of the powder silo 6, causing the discharge port 9 to discharge, the powder silo 6 needs to be cleared of blockages. In this case, the process of lowering the clearing pipe 3 is the same as that in the clearing process of Embodiment 1, except that the guide pipe 13 needs to be installed on the lower part of the first clearing branch pipe 10 in advance.

[0054] Before the conical steel body 5 enters the powder, the high-pressure air valve is opened, and high-pressure air is blown into the air pipe 4. The high-pressure air is sprayed downward from the exhaust hole 7 of the conical steel body 5. The unblocking pipe 3 continues to be lowered. The conical steel body 5 is inserted into the powder and uses its own weight and high-pressure air to vaporize the solidified powder. During the sinking process of the conical steel body 5, the high-pressure air sprayed from the exhaust hole 7 vaporizes the material and diffuses upward along the pipe wall of the unblocking pipe 3. Under the action of the guide 13, the diffusion range increases, the vaporization influence area is large, and a large vaporization zone is formed. After the unblocking pipe 3 gradually penetrates the overhead powder, the vaporized powder around the unblocking pipe 3 collapses into the overhead area, and a large hole is formed around the unblocking pipe 3. Then the unblocking pipe 3 is lifted out, and the silo cleaning winch 19 and the silo cleaning machine scraper 18 work to carry out the silo cleaning operation.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
