Technical Field

[0001] The utility model relates to the technical field of packaging devices, in particular to a dust suppression packaging device for a valve port of a lining material of a medium frequency furnace. Background Art

[0002] Medium frequency furnace linings are also called medium frequency furnace charges, which are divided into acidic, neutral and alkaline linings. Acidic linings are made of high-purity quartz and fused quartz as the main raw materials, with appropriate additives as sintering agents; neutral linings are made of fused corundum, high-purity magnesia and high-purity spinel as the main raw materials, with composite additives as sintering agents; alkaline linings are made of high-purity magnesia as the main raw material, with appropriate additives as sintering agents; acidic, neutral and alkaline linings are widely used in medium frequency induction furnaces and cored induction furnaces to melt gray cast iron, ductile iron and other iron alloys, melt carbon steel, high manganese steel, tool steel, heat-resistant steel, stainless steel and other alloy steels, melt aluminum alloys, copper alloys, etc.

[0003] When furnace lining materials are packaged in packaging bags, a valve port packaging device is required. During the discharge process of the furnace lining materials using the valve port packaging device, dust is easily generated, and the raised dust is easily inhaled into the body by the workers, thereby causing harm to the workers' health. Summary of the Invention

[0004] The utility model aims to provide a dust suppression packaging device for a valve port of a medium frequency furnace lining material in order to solve the problem in the prior art that dust is easily inhaled into the body of workers.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a dust suppression packaging device for the valve port of a medium frequency furnace lining, comprising a discharge pipe arranged below a storage bin, the discharge pipe being used to connect a packaging bag, an air suction box being installed on the outer periphery of the discharge pipe, an air suction frame being provided on one side of the opening of the air suction box, and the air suction frame being arranged toward the pipe mouth of the discharge pipe; an air suction pipe being installed on the air suction box, an air pump being installed on the air suction pipe, and a filter assembly being installed on the end of the air suction pipe away from the air suction box.

[0006] By adopting the above technical solution, the storage bin is used to store the furnace lining material, and the discharge pipe can discharge the furnace lining material into the packaging bag. Since the furnace lining material will generate dust when it is discharged from the discharge pipe into the packaging belt, the dust can be easily inhaled by the on-site staff, which can easily cause harm to the health of the staff who inhale the dust for a long time. Therefore, it is necessary to use an air suction box to absorb the dust, and the air pump is used to extract the gas in the air suction box. The air suction pipe can introduce the gas extracted from the air suction box into the filter assembly, thereby forming a negative pressure inside the air suction box. The dust will enter the interior of the air suction box under the action of air pressure, thereby realizing the absorption of the dust. The filter assembly can filter the solid particles in the dust, so that the filtered air can be discharged into the atmosphere.

[0007] Preferably, the lower frame of the air suction frame is tilted downward.

[0014] By adopting the above technical solution, a threaded hole is opened on the fixing plate, and the bolt is threadedly connected to the threaded hole of the fixing plate after passing through the through hole. By installing the fixing plate on the discharge pipe, the threaded hole can be opened on the fixing plate, so there is no need to open a hole on the discharge pipe, thereby ensuring the strength of the discharge pipe itself and avoiding damage to the discharge pipe when opening the threaded hole.

[0015] Preferably, the suction box is an annular box, and the projection surface of the suction frame is in the shape of a circular ring.

[0016] By adopting the above technical solution, the air intake box is formed in one piece, and there is no need to assemble the air intake boxes during installation, and the installation process is simpler and faster.

[0020] By adopting the above technical solution, the filter box can accommodate the dust, and the filter net can filter the dust passing through the filter net, thereby intercepting the solid particles in the dust.

[0021] Preferably, the filter assembly further comprises a movable door hinged to the filter box.

[0022] By adopting the above technical solution, solid particles can be easily discharged from the filter box after the movable door is opened, and the filter screen can be easily replaced.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The dust suppression packaging device for the valve port of the intermediate frequency furnace lining is provided with an air suction box, an air suction frame, an air suction pipe and an air pump. The air pump can be used to extract the gas in the air suction box through the air suction pipe, thereby forming a negative pressure in the air suction box.

[0033] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0034] Please refer to Figures 1 to 4 In this embodiment, a dust suppression packaging device for the valve port of a medium-frequency furnace lining material includes a discharge pipe 1 arranged below a storage bin 2, the discharge pipe 1 is used to connect a packaging bag, an air suction box 3 is installed on the outer periphery of the discharge pipe 1, an air suction frame 4 is provided on one side of the opening of the air suction box 3, and the air suction frame 4 is arranged toward the pipe mouth of the discharge pipe 1; an air suction pipe 5 is installed on the air suction box 3, an air pump 6 is installed on the air suction pipe 5, a filter assembly 7 is installed on the end of the air suction pipe 5 away from the air suction box 3, and the lower frame of the air suction frame 4 is tilted downward.

[0035] In the above scheme, the storage bin 2 is used to store furnace lining materials, and the discharge pipe 1 can discharge the furnace lining materials into the packaging bag. Since the furnace lining materials will generate dust when they are discharged from the discharge pipe 1 into the packaging belt, and the dust can be easily inhaled by the on-site staff, it is easy to cause harm to the health of the staff who inhale the dust for a long time. Therefore, it is necessary to use the suction box 3 to absorb the dust, and the air pump 6 is used to extract the gas in the suction box 3. The suction pipe 5 can make the gas extracted from the suction box 3 be introduced into the filter component 7, so that a negative pressure is formed inside the suction box 3. The dust will enter the interior of the suction box 3 under the action of air pressure, realizing the absorption of the dust. The filter component 7 can filter the solid particles in the dust, so that the filtered air can be discharged into the atmosphere, realizing the protection of the atmosphere. If the dust is directly discharged into the atmosphere without filtering, it will cause pollution to the atmosphere.

[0036] It should be noted that tilting the lower frame of the air suction frame 4 downward can increase the dust absorption area of the air suction box 3, thereby increasing the dust absorption efficiency of the air suction box 3. The packaging bag is located below the discharge pipe 1, and the packaging bag is used to package the furnace lining.

[0037] The air suction box 3 in this embodiment is detachably mounted on the discharge pipe 1 through the mounting assembly 8. The mounting assembly 8 includes a connecting plate 801 mounted on the air suction box 3. The connecting plate 801 is provided with a folded edge 802. The folded edge 802 is mounted on the discharge pipe 1 through bolts 803. A fixing plate 9 is mounted on the outer periphery of the discharge pipe 1. The air suction box 3 is detachably mounted on the fixing plate 9 through the mounting assembly 8.

[0038] In the above scheme, the connecting plate 801 is welded to the top side of the air suction box 3, and a through hole for the bolt 803 to pass through is opened on the folded edge 802. A threaded hole can be opened on the discharge pipe 1, and the bolt 803 is passed through the through hole and then threaded into the threaded hole on the discharge pipe 1. A threaded hole can also be opened on the fixing plate 9, and the bolt 803 is passed through the through hole and then threaded into the threaded hole in the fixing plate 9. By installing the fixing plate 9 on the discharge pipe 1, the threaded hole can be opened on the fixing plate 9, so that there is no need to open a hole on the discharge pipe 1, thereby ensuring the strength of the discharge pipe 1 itself and avoiding damage to the discharge pipe 1 when the threaded hole is opened.

[0039] The suction box 3 in this embodiment is an annular box 301 , and the projection surface of the suction frame 4 is in the shape of a circular ring.

[0040] In the above solution, the air suction box 3 is formed in one piece, and there is no need to assemble the air suction box 3 during installation, so the installation process is simpler and faster.

[0041] The filter assembly 7 in this embodiment includes a filter box 701 installed on the intake pipe 5, a filter screen 702 is installed on the filter box 701, an exhaust pipe 703 is installed on the filter box 701, and the filter assembly 7 also includes a movable door 704 hinged on the filter box 701, and a handle 705 is installed on the movable door 704.

[0042] In the above scheme, the filter box 701 can accommodate dust, and the filter screen 702 can filter the dust passing through the filter screen 702, thereby intercepting solid particles in the dust. The handle 705 is used to facilitate pulling the movable door 704. After the movable door 704 is opened, the solid particles can be easily discharged from the filter box 701, and the filter screen 702 can be easily replaced.

[0043] Working method: When the furnace lining needs to be collected and packaged, the packaging bag is put on the discharge pipe 1, and the furnace lining in the storage bin 2 is discharged into the discharge pipe 1. The discharge pipe 1 guides the furnace lining into the packaging bag. The furnace lining generates dust in the process of entering the packaging bag. The air pump 6 is started. The air pump 6 draws the air in the suction box 3 into the filter box 701 through the suction box 3. Negative pressure is formed in the suction box 3. Under the action of the negative pressure, the dust enters the suction box 3 through the suction frame 4, and then the dust enters the filter box 701 through the suction pipe 5. In the process, the filter screen 702 filters and intercepts the solid particles in the dust, and the filtered air is discharged into the atmosphere through the exhaust pipe 703. When the solid particles in the filter box 701 need to be cleaned, the handle 705 is pulled, and the handle 705 drives the movable door 704 to move. The movable door 704 opens, and the solid particles in the filter box 701 fall out of the filter box 701 under the influence of gravity. Then, the solid particles that cannot fall directly from the filter box 701 are manually cleaned out, and then the movable door 704 is closed. Example 2

[0044] Please refer to Figures 5 to 7 In this embodiment, the suction box 3 is a plurality of arc-shaped boxes 302, the projection surface of the suction frame 4 is arc-shaped, and the suction branch pipe 501 is installed on the arc-shaped box 302, and the arc-shaped box 302 is connected to the suction pipe 5 through the suction branch pipe 501.

[0045] In the above scheme, the suction branch pipe 501 can collect the dust absorbed by multiple arc boxes 302 into the suction pipe 5, and the suction pipe 5 can introduce the gas into the filter box 701. Compared with the first embodiment, the arc box 302 in this embodiment is easier to process than the ring box 301. A single arc box 302 is smaller in size and easier to transport after stacking. When the arc box 302 needs to be installed, align the through hole of the folded edge 802 with the threaded hole on the fixing plate 9, and pass the bolt 803 through the through hole and thread it into the threaded hole.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
