Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to a regulating device for a dust removal pipeline valve of a calcium carbide furnace batching station. Background Art

[0002] In the calcium carbide furnace production process, the feeding station's feeding belt is an indispensable conveying device. However, this area often generates a large amount of dust during the feeding process, seriously impacting the production environment and increasing worker health risks. Dust removal ducts serve as a bridge between dust-generating points and dust removal equipment, directing dust-laden gases to the dust removal equipment for treatment. Dust duct valves, installed on the dust removal ducts, control the opening and closing of the duct valves to ensure that dust generated during the feeding process is promptly collected and transported to the dust removal equipment.

[0003] There is a certain amount of research on the adjustment of the opening and closing state of the valve on the dust removal pipe of the calcium carbide furnace batching station in the prior art. Referring to the patent document with application number CN211133300U, a calcium carbide furnace dust removal system is disclosed, including: a calcium carbide furnace, a dust cover, a shrimp bend, a dust removal pipe, an electric valve, a main pipe, a support frame, an electric main valve, an elbow, a side pipe, and a bag dust collector. Dust covers are installed on the three furnace outlets on the left and right calcium carbide furnaces, and dust removal pipes are installed on the dust covers through shrimp bends. The ends of the dust removal pipes are welded to the main pipes, and electric valves are installed on the ends of the dust removal pipes. Several support frames are equidistantly welded at the bottom of the main pipe. The two ends of the main pipe are connected to the side pipes through elbows, and electric main valves are installed on the inner sides of both ends of the main pipe. The outer sides of the tops of the side pipes on both sides are also connected to the bag dust collectors through elbows; by adjusting the electric valve and the electric main valve to be in the open state, the dust removal pipe and the main pipe are circulated, thereby realizing the suction of dust.

[0004] However, by adjusting the electric valve and the electric main valve to the open state, the circulation of the dust removal pipe and the main pipeline is achieved. The electric valve and the electric main valve respond slowly. Especially when the calcium carbide furnace is frequently charged, the electric valve and the electric main valve cannot respond in time, resulting in the dust generated during the charging process cannot be sucked away in time, causing serious pollution to the production environment.

[0022] The technical solution of the present invention will be further explained below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments described below.

[0023] Reference Figure 1 A regulating device for a dust removal duct valve in a calcium carbide furnace batching station comprises an air supply assembly 1, a drive assembly 2, and an adjusting plate 3. A feed pipe 7 is disposed directly above a feeding belt 5, through which raw materials for the calcium carbide furnace fall onto the feeding belt 5. The feed pipe 7 is open at one end near the feeding belt 5, and a dust removal duct 6 is connected to the open section of the feed pipe 7. The air supply assembly 1 is connected to the drive assembly 2, and the air supply assembly 1 is used to supply compressed air to the drive assembly 2. The adjusting plate 3 has one end rotatably connected to the drive assembly 2 and the other end fixedly connected to the valve plate of the air duct valve 4, wherein the air duct valve 4 refers to a valve connected to the side wall of the dust removal duct 6.

[0024] In the present invention, when the opening degree of the air duct valve 4 needs to be adjusted, the air supply assembly 1 is first activated to provide sufficient compressed air as a power source to the driver 21. Subsequently, the driver 21 begins to work under the drive of the compressed air. The output end of the driver 21 is connected to the adjustment plate 3, and the linear motion of the driver 21 is converted into the rotational motion of the adjustment plate 3. One end of the adjustment plate 3 is fixedly connected to the valve plate of the air duct valve 4. When the adjustment plate 3 rotates, the adjustment plate 3 drives the valve plate to rotate around its rotation axis by a corresponding angle. During this process, the angle between the axial direction of the valve plate and the axial direction of the dust removal duct 6 changes. When the axial direction of the valve plate is perpendicular to the axial direction of the dust removal duct 6, the valve plate is fully open, allowing air to flow smoothly through the dust removal duct 6, at which time the maximum ventilation volume is achieved. Conversely, when the ventilation volume needs to be reduced or closed, the driver 21 drives the adjustment plate 3 to rotate in the opposite direction, causing the axial direction of the valve plate to gradually become parallel to the axial direction of the dust removal duct 6 until it is fully closed, at which time the air flow through the dust removal duct 6 is blocked.

[0025] Reference Figure 1 The drive assembly 2 includes a fixed bracket and a drive member 21. The fixed bracket is connected to the dust removal duct 6 and is used to support the drive member 21. The drive member 21 is connected to the fixed bracket, and the output end of the drive member 21 is connected to the adjustment plate 3, and the input end of the drive member 21 is connected to the air supply assembly 1. In the present invention, the drive member 21 can be a cylinder, a pneumatic motor, etc., and any arrangement in which the drive member 21 pneumatically drives the adjustment plate 3 to rotate is applicable.

[0026] Reference Figure 1 The air supply assembly 1 includes a compressed air main pipe 11, an air source branch pipe 12, and an air supply device. One end of the air source branch pipe 12 is connected to the compressed air main pipe 11, and the other end is connected to the input end of the driver 21. The compressed air main pipe 11 is connected to the air supply device, and the air supply device provides compressed air to the compressed air main pipe 11.

[0027] Reference Figure 1 A solenoid valve is connected to the air source branch pipe 12. This solenoid valve precisely controls the flow of compressed air through the air source branch pipe 12. When the solenoid valve is open, compressed air flows from the compressed air main pipe 11 through the air source branch pipe 12 to the driver 21, providing power to the driver 21. When the solenoid valve is closed, the air flow is cut off, and the driver 21 stops operating.

[0028] Example 1:

[0029] Reference Figure 1 In the regulating device of the dust removal pipeline valve of the calcium carbide furnace batching station of this embodiment, the regulating piece 3 is set to an arc structure.

[0030] In this embodiment, the regulating piece 3 is configured as an arc-shaped structure. The arc-shaped structure can effectively disperse the driving force from the driving component 2 and the reaction force when the air duct valve 4 is opened and closed, reduce stress concentration, and reduce the risk of the regulating piece 3 breaking or deforming; in addition, during the rotation of the regulating piece 3 with an arc structure, the contact and friction between the edge of the regulating piece 3 and the surrounding environment are smoother, which helps to reduce movement resistance and improve movement efficiency.

[0031] Example 2:

[0032] Reference Figure 1 In this embodiment, the regulating device for the dust removal duct valve of the calcium carbide furnace batching station is based on Example 1, and the curvature radius of the regulating plate 3 ranges from 75 mm to 80 mm. Specifically, the curvature radius of the regulating plate 3 can be 75 mm, 77 mm, or 80 mm, and the appropriate curvature radius of the regulating plate 3 can be set according to the diameter of the valve plate of the air duct valve 4. In this embodiment, the curvature radius of the regulating plate 3 is set to 80 mm.

[0033] Example 3:

[0034] Reference Figure 1 In the present embodiment, the regulating device for the dust removal pipeline valve of the calcium carbide furnace batching station comprises a driving member 21 which is a cylinder, and an adjusting piece 3 is connected to the piston rod of the cylinder.

[0035] In this embodiment, the driving member 21 is configured as a cylinder, which has a simple structure and is easy to maintain. The cylinder also operates stably, ensuring that the air duct valve 4 can be opened and closed quickly.

[0036] Example 4:

[0037] Reference Figure 1 In the regulating device of the dust removal pipeline valve of the calcium carbide furnace batching station of this embodiment, the regulating plate 3 is connected to the output end of the driving member 21 through a pin shaft, and one end of the pin shaft is rotatably connected to the regulating plate 3, and the other end is fixedly connected to the output end of the driving member 21.

[0038] In this embodiment, the output end of the driving member 21 drives the pin to move synchronously, causing the adjusting plate 3 to rotate about the pin. The rotation of the adjusting plate 3 drives the valve plate of the air duct valve 4 to rotate, thereby adjusting the open and closed state of the air duct valve 4. The pin connects the adjusting plate 3 to the air duct valve, eliminating additional transmission mechanisms and simplifying the overall structure of the regulating device for the dust removal pipeline valve of the calcium carbide furnace batching station.

[0039] Example 5:

[0040] Reference Figure 1 In the regulating device of the dust removal pipeline valve of the calcium carbide furnace batching station of this embodiment, the regulating plate 3 is connected to the output end of the driving member 21 through a hinge, and one end of the hinge is fixedly connected to the regulating plate 3, and the other end is fixedly connected to the output end of the driving member 21.

[0041] In this embodiment, the adjusting plate 3 rotates around the fixed point of the hinge, and the rotation of the adjusting plate 3 drives the valve plate of the air duct valve 4 to rotate, thereby realizing precise adjustment of the opening and closing state of the air duct valve 4, so as to meet the requirements of the dust removal effect under different working conditions.

[0042] The working principle of the regulating device of the dust removal pipeline valve of the calcium carbide furnace batching station of the utility model is: first, the air supply equipment provides compressed air to the compressed air main pipe 11, and the compressed air goes along the compressed air main pipe 11 to the driving member 21, and the driving member 21 drives the regulating piece 3 to move, and the regulating piece 3 drives the valve plate of the air duct valve 4 to rotate. When the valve plate of the air duct valve 4 is axially parallel to the dust removal pipeline 6, the air duct valve 4 is in an open state; when the valve plate of the air duct valve 4 is axially perpendicular to the dust removal pipeline 6, the air duct valve 4 is in a closed state.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
