Description

Technical Field

[0001] This invention belongs to the field of ventilation equipment technology, specifically a backup device for oxygen ducts in desulfurization towers and its usage method. Background Technology

[0002] A desulfurization tower is a tower-type equipment used to desulfurize industrial waste gas. Initially, desulfurization towers were most widely used when they were built with granite. They utilize the principle of water film desulfurization and dust removal and are also known as granite water film desulfurization and dust removal equipment or marble water film desulfurization and dust removal equipment. Their advantages are that they are easy to maintain and can achieve the effects of dust removal and desulfurization at the same time by preparing different dust removal agents.

[0003] However, in the existing technology, in order to ensure a sufficient supply of oxygen at all times, the existing desulfurization tower oxygen supply equipment needs to be equipped with a backup. This results in one existing desulfurization tower oxygen supply equipment always being idle. Electrical equipment is prone to failure after being idle for a long time. In order to ensure the normal use of the equipment, it is necessary to carry out regular maintenance on both equipment simultaneously, which increases the actual production and maintenance costs. At the same time, in an emergency, it is impossible to avoid the situation where both existing desulfurization tower oxygen supply equipment fails at the same time. The actual maintenance process is difficult, which leads to the need for overall construction shutdown, resulting in a decrease in overall construction efficiency and unsatisfactory actual use effect of the existing equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a backup device for oxygen ducts in desulfurization towers and its usage method, which can effectively reduce installation and maintenance costs, improve overall maintenance efficiency, and prevent overall construction shutdowns.

[0008] An auxiliary fan blade is rotatably connected to one side of the outer surface of the first fan blade. A limit hole is opened on one side of the outer surface of the first fan blade.

A top rod is slidably inserted inside the reset frame.

[0009] A cleaning rod is fixedly connected to the outer surface of the auxiliary fan blade, and a pressure block is fixedly connected to the inner wall of one side of the auxiliary fan blade.

[0010] One end of the connecting shaft slides through the outer surface of one side of the auxiliary fan blade, and the other end of the connecting shaft extends into the limiting hole.

[0011] One end of the rotating rod extends to the outside of the adjusting frame, and a connecting wheel is sleeved on the outer surface of the rotating rod. A drive motor is fixedly connected to one side of the outer surface of the adjusting frame, and the output end of the drive motor is fixedly connected to one end of the rotating rod. A sliding groove is formed on one side of the outer surface of the adjusting frame.

[0012] The adjusting component includes a rotating tube and a first connecting shaft. The rotating tube is rotatably connected between the inner walls of the two sides of the adjusting frame. An adjusting rod is slidably inserted inside the rotating tube. One end of the adjusting rod extends into the adjusting tube and is threadedly connected to the adjusting tube. A connecting bevel gear is sleeved on the outer surface of the adjusting rod. A pusher is rotatably connected to the outer surface of the adjusting rod. The first connecting shaft is rotatably connected to the inner wall of one side of the first bottom tube, and one end of the first connecting shaft extends to the outside of the first bottom tube. A connecting gear is sleeved on the outer surface of the first connecting shaft. A locking block is also fixedly connected to one end of the first connecting shaft.

[0013] The outer surface of the rotating tube is also fitted with a connecting wheel, and a connecting belt is fitted between the outer surfaces of the two connecting wheels.

[0015] The connecting component includes two top rings, which are slidably fitted onto the tops of the first and second bottom tubes, respectively. Each top ring is fixedly connected to a bottom ring by bolts. An extension frame is provided between the outer surfaces of one side of the two top rings. A retaining shaft is rotatably connected to the inner wall of one side of the extension frame. Both ends of the retaining shaft are also fixedly connected to retaining blocks. A top shaft is secured between one end of the retaining shaft and one end of the first connecting shaft by retaining blocks. A top shaft is also secured between the other end of the retaining shaft and one end of the second connecting shaft by retaining blocks. Limiting rings are threadedly connected to the outer surfaces of the retaining shaft near both ends. Limiting rings are also threadedly connected to the outer surfaces of the first and second connecting shafts.

[0016] A method for using a backup device for oxygen ductwork in a desulfurization tower includes the following steps:

[0017] S1. Emergency Adjustment: The equipment can be securely connected to the designated pipeline location via the connecting pipe. Then, by controlling the start of the drive motor, the drive motor drives the rotating tube to rotate via the rotating rod, connecting wheel, and connecting belt. This rotating tube then drives the adjusting rod to rotate. Simultaneously, supported by the return spring, the push rod pushes one end of the connecting shaft and one end of the adjusting rod into a tight fit. This allows the rotating adjusting rod to drive the connecting shaft to rotate, and the adjusting tube to rotate along with the connecting shaft. This, in turn, allows the connecting shaft to drive the first fan blade to rotate through the limit hole, enabling the first fan blade to generate effective airflow. The existing pipeline is injected with oxygen to supply the existing desulfurization tower. When the first blade stops rotating unexpectedly due to obstruction by a foreign object, the connecting shaft also stops rotating due to the position restriction of the limiting hole, which prevents the regulating pipe from rotating. At this time, the continuously rotating regulating rod, in its threaded connection with the regulating pipe, can gradually push the connecting shaft out of the regulating pipe and the limiting hole. At the same time, the part of the connecting shaft that restricts the regulating pipe can move to the inside of the auxiliary blade. Then, under the position restriction of the pressure block, the regulating rod can drive the auxiliary blade to rotate through the connecting shaft, and the airflow can continue to be supplied to a certain extent.

[0018] S2. Preliminary Adjustment: During the movement of the adjusting rod, the adjusting rod will drive the moving gear and the connecting gear to gradually mesh through the push frame. This allows the rotating adjusting rod to drive the connecting gear to rotate through the connecting bevel gear and the moving gear. In turn, the rotating connecting gear drives the first connecting shaft to rotate. The rotating first connecting shaft can effectively drive the second connecting shaft to rotate through the top shaft and the retaining shaft. This allows the rotating second connecting shaft to drive the second fan blade to rotate through the rotating bevel gear. The second fan blade, in conjunction with the auxiliary fan blade, can provide sufficient airflow. If the drive motor malfunctions, the corresponding connecting pipe can be easily disassembled, allowing for convenient inspection and maintenance of the drive motor.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] In this invention, the connecting pipe securely connects the device to the designated pipeline location. By controlling the start of the drive motor, the motor effectively rotates the rotating pipe via the rotating rod, connecting wheel, and connecting belt. This rotating pipe then drives the adjusting rod to rotate. Simultaneously, supported by the return spring, the push rod effectively pushes one end of the connecting shaft and one end of the adjusting rod into a tight fit. This allows the rotating adjusting rod to effectively drive the connecting shaft to rotate, and the adjusting pipe to rotate along with the connecting shaft. Finally, the connecting shaft passes through the limiting hole... The system effectively drives the first fan blade to rotate, enabling it to generate effective airflow that injects into the existing pipeline, providing the oxygen required by the existing desulfurization tower. When the first fan blade unexpectedly stops rotating due to obstruction by a foreign object, the connecting shaft also stops rotating under the position restriction of the limiting hole, thus preventing the regulating pipe from rotating. At this time, the continuously rotating regulating rod, through its threaded connection with the regulating pipe, gradually pushes the connecting shaft out of the regulating pipe and the limiting hole. Simultaneously, it allows the part of the connecting shaft that restricts the regulating pipe to effectively move into the auxiliary fan blade, thereby limiting the position of the pressure block. Under these conditions, the adjusting rod can drive the auxiliary fan blades to rotate via the connecting shaft, thus maintaining a certain level of airflow supply. This effectively prevents the entire construction process from stopping due to insufficient airflow, allowing the equipment to efficiently perform its intended functions. During the movement of the adjusting rod, the adjusting rod will drive the moving gear and connecting gear to gradually mesh via the push frame. This allows the rotating adjusting rod to effectively drive the connecting gear to rotate via the connecting bevel gear and the moving gear. The rotating connecting gear then effectively drives the first connecting shaft to rotate, which in turn drives the second connecting shaft to rotate via the top shaft and the locking shaft. The rotating second connecting shaft, in turn, drives the second fan blade to rotate via the rotating bevel gear. The second fan blade, in conjunction with the auxiliary fan blades, provides sufficient airflow. If the drive motor malfunctions, the corresponding connecting pipe can be easily disassembled, facilitating easy maintenance and repair of the drive motor. This effectively reduces actual maintenance costs, making the equipment less prone to operational failures due to improper maintenance and improving the actual performance of the equipment.

[0036] The following provides a detailed description of the usage method of a backup device for oxygen ductwork in a desulfurization tower, as provided in an embodiment of the present invention. The usage method includes the following steps:

[0037] Step 1, Emergency Adjustment: The equipment is securely connected to the designated pipeline location via connecting pipe 301. Then, the drive motor 103 is activated, enabling it to effectively rotate the rotating pipe 104 via the rotating rod, connecting wheel, and connecting belt. This rotating pipe 104 then rotates the adjusting rod 110. Simultaneously, supported by the return spring 116, the push rod 117 effectively pushes one end of the connecting shaft 111 and one end of the adjusting rod 110 into close contact. This allows the rotating adjusting rod 110 to effectively drive the connecting shaft 111 to rotate, and the adjusting pipe 109 to rotate along with the connecting shaft 111. The connecting shaft 111, through the limiting hole, effectively drives the first fan blade 114 to rotate, allowing the first fan blade 114 to generate effective airflow that is injected into the connected existing pipeline, improving airflow efficiency. To supply the oxygen required by the existing desulfurization tower, when the first blade 114 is unexpectedly blocked by a foreign object and stops rotating, the connecting shaft 111 also stops rotating under the position restriction of the limiting hole, thus preventing the regulating pipe 109 from rotating. At this time, the continuously rotating regulating rod 110, in its threaded connection with the regulating pipe 109, can gradually push the connecting shaft 111 out of the regulating pipe 109 and the limiting hole. At the same time, the part of the connecting shaft 111 that restricts the regulating pipe 109 can be effectively moved into the auxiliary blade 112. Then, under the position restriction of the pressure block, the regulating rod 110 can drive the auxiliary blade 112 to rotate through the connecting shaft 111. At the same time, the airflow can continue to be supplied to a certain extent, thus effectively preventing the overall construction from stopping due to the lack of airflow supply, and enabling the equipment to efficiently perform its intended functions.

[0038] Step 2, Preliminary Adjustment: During the movement of the adjusting rod 110, the adjusting rod 110 will drive the moving gear 106 and the connecting gear to gradually mesh through the push frame 105. This allows the rotating adjusting rod 110 to effectively drive the connecting gear to rotate through the connecting bevel gear and the moving gear 106. In turn, the rotating connecting gear can effectively drive the first connecting shaft 107 to rotate. The rotating first connecting shaft 107 can effectively drive the second connecting shaft 202 to rotate through the top shaft 304 and the retaining shaft 305. This allows the rotating second connecting shaft 202 to effectively drive the second fan blade 204 to rotate through the rotating bevel gear. The second fan blade 204, in conjunction with the auxiliary fan blade 112, can provide sufficient airflow. If the drive motor 103 malfunctions, the corresponding connecting pipe 301 can be easily disassembled, allowing for convenient maintenance of the drive motor 103. This effectively reduces actual maintenance costs, makes the equipment less prone to operational failures due to improper maintenance, and improves the actual performance of the equipment.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

Limiting rings (306) are threadedly connected to the outer surfaces of the retaining shaft (305) near both ends. Limiting rings (306) are also threadedly connected to the outer surfaces of the first connecting shaft (107) and the second connecting shaft (202).

2. A method for using backup equipment for oxygen ducts in a desulfurization tower, characterized in that, The application of this equipment in a desulfurization tower oxygen duct backup device as described in claim 1 includes the following steps: S1. Emergency Adjustment: The device can be securely connected to the designated pipeline position via the connecting pipe (301). Then, by controlling the start of the drive motor (103), the drive motor (103) can drive the rotating pipe (104) to rotate via the rotating rod, connecting wheel, and connecting belt. The rotating pipe (104) can then drive the adjusting rod (110) to rotate. At the same time, under the support of the return spring (116), the push rod (117) can push one end of the connecting shaft (111) and one end of the adjusting rod (110) to fit tightly together. The rotating adjusting rod (110) can then drive the connecting shaft (111) to rotate, and the adjusting pipe (109) can rotate with the connecting shaft (111). The connecting shaft (111) can then drive the first fan blade (114) to rotate through the limiting hole. It can generate an effective flow of air into the existing pipeline to provide the oxygen required by the existing desulfurization tower. When the first blade (114) is blocked by a foreign object and stops rotating unexpectedly, the connecting shaft (111) also stops rotating under the position restriction of the limiting hole, which makes the regulating pipe (109) unable to rotate. At this time, the continuously rotating regulating rod (110) can gradually push the connecting shaft (111) out of the regulating pipe (109) and the limiting hole under the threaded connection with the regulating pipe (109). At the same time, the part of the connecting shaft (111) that restricts the regulating pipe (109) can move into the auxiliary blade (112). Under the position restriction of the pressure block, the regulating rod (110) can drive the auxiliary blade (112) to rotate through the connecting shaft (111), and at the same time, the flow of air can continue to be supplied to a certain extent. S2, Preliminary Adjustment: During the movement of the adjustment rod (110), the adjustment rod (110) will drive the moving gear (106) and the connecting gear to gradually mesh through the push frame (105), so that the rotating adjustment rod (110) can drive the connecting gear to rotate through the connecting bevel gear and the moving gear (106), so that the rotating connecting gear can drive the first connecting shaft (107) to rotate, so that the rotating first connecting shaft (107) can effectively drive the second connecting shaft (202) to rotate through the top shaft (304) and the locking shaft (305), so that the rotating second connecting shaft (202) can drive the second fan blade (204) to rotate through the rotating bevel gear, so that the second fan blade (204) can provide sufficient airflow in conjunction with the auxiliary fan blade (112). If the drive motor (103) fails, the corresponding side connecting pipe (301) can be easily disassembled, so that the drive motor (103) can be easily inspected and maintained.
