Description

Technical Field

[0001] This utility model relates to the field of environmental protection dust removal valve technology, and in particular to a rotating mechanism and a mechanical adjustment device for dust removal valves. Background Technology

[0002] In industrial dust collection systems, dust collection valves are core components for controlling the opening and closing of dust collection ducts and regulating the airflow at dust collection points. Currently, butterfly valves are commonly used in industries such as steel and metallurgy. They are primarily driven by pneumatic or electric actuators, and their operation is limited to a simple "fully open, fully closed" shut-off control, lacking manual adjustment mechanisms. With increasingly stringent environmental requirements (such as ultra-low emissions) and the need for energy efficiency optimization, it is necessary to finely allocate airflow at each dust collection point to balance environmental compliance with reduced fan energy consumption.

[0003] In the existing solutions, replacing the valve with a brand new one with a manual device is not only costly but also time-consuming. If conventional manual conversion parts are used, there are problems such as "the valve opening cannot be fixed and each adjustment requires repeated on-site operation" and "the transmission is prone to slippage and the adjustment accuracy is low". Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to solve the problem of resetting the opening degree after each switch of a conventional manual device.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a rotating mechanism, which includes a first rotating component whose outer wall is engaged with a second rotating component, one end of the first rotating component being engaged with a valve, and a handle being fixedly connected to the outer wall of the second rotating component, wherein two handles are provided symmetrically.

[0006] In a preferred embodiment of the rotating mechanism of this utility model: the first rotating component includes a rotating column, and a protrusion is fixedly connected to one end of the rotating column, the protrusion being rectangular.

[0007] In a preferred embodiment of the rotating mechanism of this utility model: a first tooth is fixedly connected to one end of the rotating column, and a fixed base is fixedly connected to one end of the first tooth.

[0008] In a preferred embodiment of the rotating mechanism described in this utility model: a through hole is provided at the bottom of the fixed base.

[0009] In a preferred embodiment of the rotating mechanism of this utility model: a groove is provided on the side of the rotating column near the through hole, and the groove is rectangular.

[0010] In a preferred embodiment of the rotating mechanism of this utility model: the second rotating component includes a hollow cylinder, and a second tooth is fixedly connected to the inner wall of the hollow cylinder, and the first tooth meshes with the second tooth.

[0011] The beneficial effects of this utility model are as follows: the symmetrical handle and meshing transmission design make adjustment effortless and can be operated by a single person. When manual adjustment is required, turning the handle will drive the rotating column to rotate through the meshing of the teeth, realizing the seamless switching between automatic and manual drive. Each time the actuator moves, the valve will automatically open to the adjusted opening degree, eliminating the need for repeated manual adjustment of the valve opening degree. Through the meshing transmission and rectangular anti-slip interface, the valve opening degree can be continuously adjusted.

[0012] The technical problem that this utility model also needs to solve is: to solve the problem of valve opening adjustment without replacing the valve.

[0013] The above-mentioned technical problem is solved by the following technical solution: one end of the valve is inserted into one end of the first rotating component, and the other end of the first rotating component is inserted into the actuator.

[0014] In a preferred embodiment of the dust removal valve mechanical adjustment device of this utility model: one end of the valve is fixedly connected to the flange of the mounting base, the mounting base includes two flanges and a connecting rod connecting the flanges, and the actuator is fixedly connected to the other flange of the mounting base.

[0015] In a preferred embodiment of the dust removal valve mechanical adjustment device of this utility model: the fixed base is rotatably connected to the flange of the mounting base.

[0016] In a preferred embodiment of the dust removal valve mechanical adjustment device of this utility model: a rotating rod is installed inside the valve, one end of the rotating rod is inserted into the groove, and one end of the protrusion is inserted into the actuator.

[0017] The beneficial effects of this utility model are as follows: by inserting the rotating rod inside the valve into the rectangular groove of the rotating column, and the rectangular protrusion of the rotating column into the output interface of the actuator, the mounting base is first fixed, and the fixed base of the first rotating component is fastened to the flange of the mounting base. The rotating column is then inserted into the valve rotating rod and the actuator for plug-in connection, so that the actuator can drive the valve to open and close, and the valve opening and closing can also be adjusted manually, without the need to disassemble or replace the valve.

[0019] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0021] Reference Figure 1 This embodiment provides a mechanical adjustment device for a rotating dust removal valve 3, including a first rotating component 1 with a second rotating component 2 engaged on its outer wall, one end of the first rotating component 1 being engaged with the valve 3, and a handle 21 being fixedly connected to the outer wall of the second rotating component 2, with two symmetrical handles 21.

[0022] The first rotating component 1 and the second rotating component 2 form a power transmission relationship through the meshing of their outer walls. The transmission ratio of the meshing transmission method of the outer walls of the components is fixed, which can realize stepless fine adjustment of the opening of the valve 3. This solves the problem of inconsistent adjustment caused by directly moving the valve stem in conventional manual modification. One end of the first rotating component 1 directly engages with the valve 3 to ensure that the power can be accurately applied to the valve 3. The second rotating component 2 has two symmetrically distributed handles 21 fixed to its outer wall by welding or other methods. The symmetrical handle 21 design makes the force balanced when the operator applies force. Compared with the operation of a single handle 21, it reduces the force intensity and avoids device deviation caused by applying force on one side.

[0023] When the opening of valve 3 needs to be manually adjusted, the operator holds the two symmetrical handles 21 with both hands and turns the handles 21 clockwise or counterclockwise. The handles 21 drive the second rotating component 2 to rotate. The second rotating component 2 drives the first rotating component 1 to rotate synchronously through the meshing relationship with the first rotating component 1. Then, through the engagement connection between the first rotating component 1 and valve 3, the internal components of valve 3 are driven to move, thereby realizing the opening adjustment.

[0024] Furthermore, the first rotating component 1 includes a rotating column 11, one end of which is fixedly connected to a protrusion 12, which is rectangular.

[0025] The main body of the first rotating component 1 is a cylindrical rotating column 11, one end of which is fixed with a rectangular protrusion 12 by welding or integral molding. The rectangular protrusion 12 is used to insert into the output interface of the original actuator 4 of the dust removal valve 3, the cylinder or the motor. When the actuator 4 is started, its output shaft drives the rotating column 11 to rotate through the rectangular protrusion 12. When manually adjusted, the rotation of the rotating column 11 will not affect the connection between the protrusion 12 and the actuator 4, realizing automatic drive and manual drive. The rectangular protrusion 12 and the rectangular interface of the actuator 4 are matched without any circumferential rotation gap, which can avoid the idle slippage when the actuator 4 is driven.

[0026] Specifically, a first tooth 13 is fixedly connected to one end of the rotating column 11, and a fixed base 14 is fixedly connected to one end of the first tooth 13.

[0027] The rotating column 11 has a first tooth 13 fixed near the center, which is an external gear. The fixed base 14 is used to rotatably connect the first rotating component 1 to the mounting base 5. When the rotating handle 21 drives the second rotating component 2, the first tooth 13 and the second tooth 23 mesh and transmit power. The fixed base 14 can limit the axial movement of the first rotating component 1 and ensure the stability of the meshing process. When the actuator 4 drives the rotating column 11, the fixed base 14 can also provide support for the rotating column 11 and prevent it from swaying radially.

[0028] Furthermore, the bottom of the fixed base 14 has a through hole 15, and the rotating column 11 has a groove 16 on the side near the through hole 15. The groove 16 is rectangular.

[0029] The fixed base 14 has multiple through holes 15 evenly distributed on it. Bolts are screwed into the through holes 15. A rectangular groove 16 is provided at the end of the rotating column 11 away from the protrusion 12. The fixed base 14 is fastened to the flange of the mounting base 5 by bolts passing through the through holes 15, thus fixing the first rotating component 1. At the same time, the rotating rod of the valve 3 is inserted into the rectangular groove 16. When the rotating column 11 rotates, the rectangular groove 16 drives the rotating rod to rotate synchronously, thereby adjusting the angle of the valve 3 blade. The rectangular groove 16 and the rotating rod of the valve 3 have a surface contact fit, which avoids wear of the rotating rod caused by point contact and transmits torque evenly.

[0030] Furthermore, the second rotating component 2 includes a hollow cylinder 22, and a second tooth 23 is fixedly connected to the inner wall of the hollow cylinder 22, with the first tooth 13 meshing with the second tooth 23.

[0031] The main body of the second rotating component 2 is a hollow cylinder 22. The inner wall of the hollow cylinder 22 is fixed with a second tooth 23, which is an internal gear that matches the first tooth 13 to ensure meshing. The hollow cylinder 22 is sleeved on the outside of the first tooth 13, and the two form a meshing pair. When the operator turns the handle 21, the handle 21 drives the hollow cylinder 22 to rotate. The second tooth 23 on the inner wall of the hollow cylinder 22 drives the first tooth 13 to rotate, which in turn drives the rotating column 11 to rotate. After the adjustment is completed, the hollow cylinder 22 can remain stationary and does not affect the actuator 4 from driving the valve 3 through the rotating column 11.

[0032] Specifically, one end of valve 3 is inserted into one end of the first rotating component 1, and the other end of the first rotating component 1 is inserted into the actuator 4.

[0033] The first rotating component 1 is connected by a plug-in connection at both ends. One end of the first rotating component 1 is plugged into the rotating rod of the valve 3 through a rectangular groove 16, and the other end is plugged into the output shaft of the actuator 4 through a rectangular protrusion 12. During the modification, there is no need to disassemble the valve 3. It is only necessary to insert the protrusion 12 of the first rotating component 1 into the interface of the actuator 4 and insert the groove 16 into the rotating rod of the valve 3. The plug-in connection does not require welding, cutting or other processing of the original valve 3 and actuator 4, and completely preserves the function and service life of the original equipment. If it is necessary to restore the original state after the modification, it is only necessary to remove this device. When the actuator 4 is driven, the power is transmitted to the rotating column 11 through the protrusion 12. When manually adjusted, the power is transmitted to the rotating column 11 through meshing. The two do not interfere with each other. There is no need for a mechanical switching structure between automatic and manual modes. The operator can turn the handle 21 to adjust at any time as needed.

[0034] Furthermore, one end of the valve 3 is fixedly connected to the flange of the mounting base 5. The mounting base 5 includes two flanges and a connecting rod connecting the flanges. The other flange of the mounting base 5 is fixedly connected to the actuator 4.

[0035] The mounting base 5 is a frame structure with two flanges and a connecting rod: the two flanges are connected by a connecting rod, and the connecting rod is fixed to the flange by welding. The interior of the mounting base 5 is a hollow structure. During installation, one flange of the mounting base 5 is first fastened to the flange of the valve 3 with bolts, and then the other flange of the mounting base 5 is connected to the flange of the actuator 4. By adjusting the length of the connecting rod, the distance between the valve 3 and the actuator 4 can be extended, providing sufficient installation space for the first and second rotating parts 2. The hollow structure makes it easy for operators to observe the transmission status and carry out subsequent maintenance.

[0036] Furthermore, the fixed base 14 is rotatably connected to the flange of the mounting base 5, and a rotating rod is installed inside the valve 3. One end of the rotating rod is inserted into the groove 16, and one end of the protrusion 12 is inserted into the actuator 4.

[0037] The fixed base 14 is fixed to the flange of the mounting base 5 near the valve 3 by bolts. The rotating rod inside the valve 3 is inserted into the rectangular groove 16 of the rotating column 11. The rectangular protrusion 12 of the rotating column 11 is inserted into the output interface of the actuator 4. First, the mounting base 5 is fixed, and the fixed base 14 of the first rotating component 1 is fastened to the flange of the mounting base 5. The rotating column 11 is inserted and connected to the rotating rod of the valve 3 and the actuator 4. The second rotating component 2 is fitted to ensure that the first and second teeth 23 are engaged. The symmetrical handle 21 is rotated by both hands. The second rotating component 2 drives the first rotating component 1 to rotate. The rotating column 11 drives the rotating rod of the valve 3 through the groove 16 to adjust the valve 3 blade angle to the target opening. The handle 21 is stopped. The actuator 4 signal (i.e., the sensor, installed on one side of the actuator 4) is associated with the proximity switch signal (i.e., the sensor is installed next to the handle 21 or the hollow cylinder 22). When the actuator 4 controls the valve 3 to open to the manually adjusted opening, the handle 21 is close to the proximity switch to send a positioning signal to stop the actuator 4 from moving, thus realizing the valve 3 opening maintenance function.

[0038] When the actuator 4 is activated, it drives the rotating column 11 to rotate through the protrusion 12, which in turn drives the valve 3 to rotate to the preset opening degree. When the proximity switch triggers the signal, the actuator 4 stops. After the valve 3 opening degree is manually adjusted, the actuator 4's stroke is changed by using the proximity switch and the second rotating component 2. Each time the actuator 4 is activated, the valve 3 is automatically opened to the adjusted opening degree, eliminating the need for repeated manual adjustment of the valve 3 opening degree.

[0039] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
