Description

Technical Field

[0001] The present disclosure relates to the technical field of desulfurization, and in particular to a feeding device. Background Art

[0002] In the glass production process, the glass kiln generates high temperatures by burning natural gas to melt the glass. During the natural gas combustion process, waste gas containing sulfides is produced. In order to make the waste gas meet the emission standards, slaked lime needs to be added to the waste gas for desulfurization.

[0003] The current feeding device includes a silo and a pipeline. The two ends of the pipeline are used to connect with the desulfurization tower and the gas source respectively. The pipeline is provided with an installation port. The silo is connected with the pipeline through the installation port. The high-pressure airflow ejected by the gas source can blow the slaked lime that falls from the silo into the pipeline into the desulfurization tower.

[0004] However, when implementing the present invention, the inventors found that since slaked lime easily reacts with water and carbon dioxide to form large granular or blocky calcium carbonate, the heavy weight of calcium carbonate may prevent the airflow from blowing it into the desulfurization tower, causing blockage in the pipeline, affecting the stability of the feed, and reducing the desulfurization efficiency.

[0056] like Figure 1 and Figure 2 As shown, the present application provides a feeding device, comprising:

[0057] A material silo 1, a material feeding pipeline 2, a gas transmission pipeline 3, a driving mechanism 4 and a spiral structure 5.

[0058] The side wall of the feeding pipeline 2 is connected to the silo 1; the air pipeline 3 is connected to the first end of the feeding pipeline 2 in a sealed and rotatable manner around a first direction; the air outlet 31 of the air pipeline 3 is located between the first end of the feeding pipeline 2 and the discharge port of the silo 1; the air inlet of the air pipeline 3 is located outside the feeding pipeline 2 for connection with the air source; the first direction is the same as the length direction of the feeding pipeline 2; the driving mechanism 4 is respectively connected to the feeding pipeline 2 and the air pipeline 3, and the driving mechanism 4 is used to drive the air pipeline 3 to rotate around the first direction; the spiral structure 5 is located between the feeding pipeline 2 and the air pipeline 3, and the spiral structure 5 is arranged on the outer wall of the air pipeline 3; the spiral structure 5 is opposite to the discharge port of the silo 1.

[0059] The feeding device of the present application can be used for feeding slaked lime in a desulfurization device, and can also be used for feeding powdered additives in a cement production process to ensure that the additives enter the production process evenly and stably; it can also be used in the pharmaceutical industry to feed some fine powdered pharmaceutical raw materials. The spiral structure 5 and the rotating gas pipeline 3 ensure that the raw materials are not blocked during transportation and are discharged evenly, thereby meeting the requirements for accurate and stable supply of raw materials in the pharmaceutical process, etc.

[0060] Specifically, the silo 1 can be buffered and adjusted at the material supply end and the use end. The silo 1 can be filled manually or automatically; when automatic filling is selected, the silo 1 can be sealed and connected to the automatic feeding equipment through a flexible sealing pipe (such as a natural rubber pipe, a polytetrafluoroethylene hose, etc.) to reduce the contact between the material and the environment, while ensuring the working environment.

[0061] The feeding pipeline 2 is used to transport the materials dropped in the silo 1 to the next process. The side wall of the feeding pipeline 2 has an installation port, and the silo 1 can be sealed and connected to the installation port of the feeding pipeline 2 through a flange and a gasket; or, when the silo 1 and the feeding pipeline 2 are both made of metal materials, the two can be sealed and connected by welding to achieve continuous and stable transportation of the materials in the silo 1 to the feeding pipeline 2. When the feeding device of the present application is applied to a desulfurization device, the second end of the feeding pipeline 2 is used to communicate with the desulfurization tower.

[0062] The gas pipeline 3 is used to transport the gas of the gas source to the feeding pipeline 2, and to carry the spiral structure 5 to drive the spiral structure 5 to rotate synchronously. The gas pipeline 3 needs to have a certain rigidity to carry the spiral structure 5, and the gas pipeline 3 can be made of metal. The feeding device can also include a packing 15, and the packing 15 can be connected to the outer wall of the gas pipeline 3 through a clamp, and the packing 15 is tightly fitted with the inner wall of the first end of the feeding pipeline 2 to achieve sealing; or, the feeding device can also include a lip seal, and the first end of the feeding pipeline 2 and the gas pipeline 3 is sealed and rotated through the lip seal. The present application preferably uses a relatively simple structure and low-cost packing 15 for sealing.

[0063] The inner diameter of the gas pipeline 3 is smaller than the inner diameter of the feeding pipeline 2. The outer wall of the gas pipeline 3 is spaced from the inner wall of the feeding pipeline 2. In order to ensure that the gas can be evenly distributed in the feeding pipeline 2 during the transportation process, the axis of the gas pipeline 3 and the axis of the feeding pipeline 2 can coincide.

[0064] The gas outlet 31 of the gas pipeline 3 may be opposite to or not opposite to the discharge port of the silo 1. The present application preferably has the gas outlet 31 not opposite to the discharge port to ensure that the gas discharged from the gas outlet 31 has a blowing effect on the fallen and crushed materials, avoids material accumulation, and avoids the materials blocking the gas outlet 31. The gas source of the present application can be selected from inert gas or air, etc. In order to reduce costs, the present application preferably uses air as the gas source. In order to ensure the blowing effect of the air flow, the air supply port pressure can be greater than 0.4MPa. The gas outlet 31 of the gas pipeline 3 can be connected to the gas source through a rotary joint 16.

[0065] The driving mechanism 4 is used to provide power for the gas pipeline 3 to rotate around the first direction, so that the gas pipeline 3 can continuously and stably rotate. The driving mechanism 4 may include a motor 41, a gear and an outer gear ring. The motor 41 may be arranged on the outer wall of the feeding pipeline 2. The driving end of the motor 41 is fixedly connected to the gear. The outer gear ring is fixedly sleeved on the gas pipeline 3. The gear is meshed with the outer gear ring. The motor 41 drives the gear to rotate around the first direction, driving the outer gear ring and the gas pipeline 3 to rotate around the first direction.

[0066] The spiral structure 5 is used to break up the large particles or block-shaped materials that have fallen down. The spiral structure 5 may include a long spiral blade, the length direction of the spiral blade is consistent with the first direction, and the outer wall of the gas pipeline 3 is fixedly connected to the inner side of the spiral rod; the spiral blade can be connected to the gas pipeline 3 by bolts; or, when the spiral structure 5 and the spiral blade are both made of metal materials, the two can be connected by welding. Alternatively, the surface of the gas pipeline 3 can be made with a spiral protrusion by mechanical processing or mold forming, and the spiral protrusion forms the spiral structure 5.

[0067] The rotation direction of the gas pipeline 3 can be adapted to the spiral rotation direction of the spiral structure 5. For example, when the gas pipeline 3 rotates clockwise around the first direction, the spiral rotation direction of the spiral structure 5 is right-handed, and the material will be thrown to the second end of the feeding pipeline 2 along the spiral direction of the spiral structure 5.

[0068] Through the above technical scheme, the feeding device provided by the present invention drives the gas pipeline 3 to rotate around the first direction through the driving mechanism 4, and drives the spiral structure 5 arranged on the gas pipeline 3 to rotate synchronously. Since the spiral structure 5 is opposite to the discharge port of the silo 1, the rotating spiral structure 5 can timely crush and disperse the large particles and block materials falling from the discharge port to prevent the particles from agglomerating, thereby avoiding the situation where the airflow cannot be blown due to the particles being too large.

[0069] Since the gas outlet 31 of the gas transmission pipeline 3 is located between the first end of the feeding pipeline 2 and the discharge port of the silo 1, the gas discharged from the gas outlet 31 can blow the fallen and broken materials to prevent the materials from being blocked during the transportation process. In addition, the gas transmission pipeline 3 is connected to the first end of the feeding pipeline 2 in a sealed rotation around the first direction, which prevents the materials from leaking into the external environment, keeps the production environment clean, avoids the waste of materials, and at the same time prevents the materials from wearing the connection between the two, thereby extending the service life of the equipment.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the discharge port of the silo 1 has a first edge 101 and a second edge 102 along a first direction, and the first edge 101 is close to the first end of the feeding pipeline 2 relative to the second edge 102; the air outlet 31 is located between the first end of the feeding pipeline 2 and the first edge 101.

[0071] Specifically, when the feed opening can be rectangular, the edge of the feed opening along the first direction close to the first end of the feeding pipeline 2 is the first edge 101, and the edge opposite thereto is the second edge 102; or, the feed opening can be circular, the first edge 101 and the second edge 102 are both straight lines tangent to the edge of the feed opening, and the tangent straight line is the same as the second direction, the second direction is perpendicular to the first direction, and the plane where the first direction and the second direction are located is a horizontal plane. The air outlet 31 is arranged between the first end of the feeding pipeline 2 and the first edge 101, so as to ensure that the gas discharged from the air outlet 31 has a blowing effect on the dropped and crushed materials, avoid material accumulation, and avoid the materials blocking the air outlet 31.

[0072] like Figures 1 to 3 As shown, in some embodiments, the first end of the spiral structure 5 is located between the first edge 101 and the first end of the feeding pipeline 2; the first end of the spiral structure 5 is connected to the outer wall of the gas pipeline 3; the second end of the spiral structure 5 is located between the second edge 102 and the second end of the feeding pipeline 2.

[0073] Specifically, the spiral structure 5 covers the range of the material falling from the material discharge port along the first direction. The size of the spiral structure 5 along the second direction can be greater than or equal to the size of the material discharge port along the second direction, and the spiral structure 5 is directly opposite to the material discharge port, so that the spiral structure 5 covers the range of the material falling from the material discharge port along the second direction. When the material falls from the material discharge port, the spiral structure 5 can crush all the material falling from the material discharge port, thereby enhancing the crushing range.

[0074] The port at the first end of the gas pipeline 3 can form an air outlet 31, so that the airflow can be ejected in the first direction to enhance the blowing effect. At this time, the second end of the spiral structure 5 and the spiral section of the spiral structure 5 facing the first edge 101 and the second edge 102 are not connected to the gas pipeline 3, but are suspended, and the overall structure is simpler.

[0075] In order to make the helical structure 5 more stable, Figure 4 As shown, in some embodiments, it also includes:

[0076] At least three support rods 6 are located in the feeding pipeline 2; the first ends of the at least three support rods 6 are arranged at equal intervals along a circular trajectory on the outer wall of the first end of the gas pipeline 3; the spiral structure 5 is connected to the at least three support rods 6;

[0077] The port at the first end of the gas delivery pipeline 3 forms a gas outlet 31 .

[0078] Specifically, the number of support rods 6 can be three, four, five or even more. In order to ensure the jet effect of the air outlet 31, the number of support rods 6 is preferably three. In order to ensure the jet effect of the air outlet 31, at least three support rods 6 can be located between the feeding pipeline 2 and the gas pipeline 3, and at least three support rods 6 can be connected to the first end of the gas pipeline 3 through a clamp; or, when at least three support rods 6 and the gas pipeline 3 are made of metal material, at least three support rods 6 can be welded to the outer wall of the first end of the gas pipeline 3. At least three support rods 6 need to have a certain rigidity, so that the second end of the spiral structure 5 and the spiral sections of the spiral structure 5 that are opposite to the first edge 101 and the second edge 102 are connected to at least three support rods 6 to improve the stability of the spiral structure 5. The inner side of the spiral structure 5 can be connected to at least three support rods 6 by welding or bolting.

[0079] like Figure 4 As shown, in some embodiments, it also includes:

[0080] The support ring 7 is located in the feeding pipeline 2; the support ring 7 is located between the second edge 102 and the second end of the feeding pipeline 2, and the second ends of at least three support rods 6 are arranged on the support ring 7 at equal intervals along a circular trajectory.

[0081] Specifically, the second ends of at least three support rods 6 can be connected to the inner wall or outer wall of the support ring 7. In order to ensure the jetting effect of the air outlet 31, the present application preferably connects the second ends of at least three support rods 6 to the inner wall of the support ring 7 by welding or threaded connection.

[0082] like Figure 5 and Figure 6 As shown, in some embodiments, it also includes:

[0083] A guide plate 8, a gas outlet 31 is arranged on the side wall of the gas pipeline 3, the guide plate 8 is connected to the side wall of the gas pipeline 3, and the guide plate 8 is used to guide the gas discharged from the gas outlet 31;

[0084] The first end of the gas delivery pipeline 3 is located between the second edge 102 and the second end of the feeding pipeline 2 .

[0085] Specifically, the spiral structure 5 can be completely arranged in the gas pipeline 3 so that the spiral structure 5 is not suspended in the air, so as to enhance the stability of the spiral structure 5. The number of gas outlets 31 can be one or more. When the number of gas outlets 31 is more than one, the multiple gas outlets 31 can be arranged at intervals around the axis of the gas pipeline 3. The guide plate 8 can be connected to the side wall of the gas pipeline 3 with bolts; or, when the guide plate 8 and the gas pipeline 3 are both made of metal, the two can be welded. The first surface of the guide plate 8 is close to the second end of the feed pipeline 2 relative to the second surface, and the first surface of the guide plate 8 has an acute angle with the first direction, that is, the guide plate 8 as a whole can be tilted toward the second end of the feed pipeline 2, so as to realize the diversion of the gas discharged from the gas outlet 31 and guide the gas to the second end of the feed pipeline 2.

[0086] like Figure 1 and Figure 2 As shown, in some embodiments, the driving mechanism 4 includes:

[0087] The motor 41 is located outside the feeding pipeline 2 and connected to the feeding pipeline 2;

[0088] A first sprocket 42 is connected to a driving end of the motor 41;

[0089] The second sprocket is sleeved on the gas transmission pipeline 3;

[0090] The chain ring 44 surrounds the first sprocket 42 and the second sprocket and meshes with both.

[0091] Specifically, the motor 41 can be bolted or clamped to the outer wall of the feeding pipeline 2. The first sprocket 42, the second sprocket and the chain ring 44 are all located outside the feeding pipeline 2. Due to the transmission mode of chain and sprocket, the meshing of the chain and sprocket can provide stable power transmission, so that the rotation of the gas pipeline 3 is more stable.

[0092] like Figure 1 and Figure 2 As shown, in some embodiments, the driving mechanism 4 further includes:

There can be one or more bearings 46, such as two, three, four, etc., wherein preferably there are two bearings 46, and the two bearings 46 can be respectively located on both sides of the second sprocket to ensure the stability of the rotation of the gas delivery pipeline 3.

The first vibrator 10 can be connected to the outer wall of the bin 1 by bolts or rivets. The first vibrator 10 can be an electromagnetic vibrator or a vibrating cylinder.

[0102] The second vibrator 11 can be connected to the outer wall of the feeding pipeline 2 by means of bolts or rivets. The second vibrator 11 can be an electromagnetic vibrator or a vibrating cylinder.

The manual gate valve 13 provides the operator with a means to directly intervene in the material unloading. In some special cases (such as equipment commissioning, emergency handling, etc.), the operator can flexibly control the flow of materials by manually operating the gate valve. The automatic unloading valve 14 automatically operates according to the preset program during normal production, reducing the workload of the operator. The dual setting of the manual gate valve 13 and the automatic unloading valve 14 also provides double protection for the unloading process.
