Description

Technical Field

[0001] The present application relates to the technical field of electrostatic precipitator equipment, and in particular to a cathode rapping device for an electrostatic precipitator. Background Art

[0002] At present, the cathode system of domestic electrostatic precipitators mostly adopts a combination of large and small frames, with side vibration or top vibration. Its function is to remove the dust attached to the cathode line by vibration through the vibration force acting on the frame. The cleaning effect is different due to the different vibration tangential force. The current main vibration methods include: top vibration system and side vibration system.

[0003] The side rapping system requires a large discharge distance between the cathode components and the anode and shell components, so the longitudinal span of the shell is large and the economic cost is high. Compared with the side rapping system, the top rapping can reduce the longitudinal internal space; in the same space, the electrostatic precipitator using top rapping can arrange more plates and wires, which can increase the dust collection area. In the two different rapping methods, the rapping force acts on the cathode frame, but the frame is affected by the structure. Regardless of whether the rapping force is downward or horizontal, the cathode large frame or the cathode hanging beam fixes and suspends the small frame, so that the cathode small frame generates a reaction force to the rapping force during rapping, which weakens the rapping force and causes the rapping acceleration of the cathode small frame to decay, resulting in insufficient cathode rapping force, poor cathode cleaning effect, and serious cathode wire dust wrapping.

[0004] Therefore, how to effectively clean the cathode wire is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The purpose of the present application is to provide a cathode rapping device for an electrostatic precipitator which can effectively clean the cathode wire.

[0006] The present application provides a cathode rapping device for an electrostatic precipitator, comprising the following components:

[0007] Support beams, which insulate the suspension and are used to support the cathode frame;

[0008] A cathode frame, comprising a main frame and a main mast that are fixedly connected, wherein the main frame is used to fix the cathode wire, and the main mast is suspended from the support beam;

[0009] The rapping device comprises a driving component, a transmission component and a rapping component, wherein the driving component drives the rapping component to move through the transmission component so as to apply an upward rapping force to the main mast.

[0010] In the present application, the main frame is suspended on the support beam through the main mast, and the main mast can move upward relative to the support beam. In this way, when the rapping component applies an upward force to the main mast, the main mast moves upward relative to the support beam, and thus no reaction force from other structures other than the main frame's own gravity is generated. In this way, the rapping force and rapping acceleration acting on the cathode frame are not easy to attenuate, thereby improving the dust removal efficiency of the cathode wire, being able to effectively remove dust from the cathode wire, and thus improving the dust removal efficiency of the electrostatic precipitator, so that the electrostatic precipitator can operate efficiently and stably for a long time.

[0011] Moreover, the rapping device in the embodiment of the present application has a simple structure and is easy to manufacture and install. It can greatly reduce the length of the shell and the cost of the steel structure, shorten the length of the shell, and reduce the electric field layout space of the electrostatic precipitator.

The crank includes a first section and a second section that are integral and at a certain angle. The end of the first section away from the rotating shaft is connected to the driving component, and the rapping component is arranged at the end of the second section away from the rotating shaft.

DETAILED DESCRIPTION

[0023] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the objectives, technical solutions and advantages of the present application more clear, the present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0024] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a cathode rapping device for an electrostatic precipitator in an embodiment provided in the present application.

[0025] The present application provides a cathode rapping device for an electrostatic precipitator, comprising a support beam 10, a cathode frame and a rapping device.

[0026] The support beam 10 in the embodiment of the present application is insulated and suspended to support the cathode frame. For example, the support beam 10 can be suspended on the shell of the electrostatic precipitator or a fixed foundation in the external environment through an insulating component such as a porcelain bottle. The support beam 10 is usually a horizontal beam, that is, a beam body in the horizontal direction.

[0027] In an embodiment of the present application, the cathode frame includes a main frame and a main mast 11 fixedly connected, the main frame may include N upper and lower triangular reinforced frames 12, a number of cathode wires 13 are fixed to the triangular reinforced frames 12, the bottom edge of the triangular reinforced frames 12 is roughly horizontally arranged, and the cathode wires 13 are fixed on the bottom edge.

[0028] The main frame is used to fix the cathode wire, and the main mast 11 is suspended from the support beam 10 so that the main mast 11 can move upward within a predetermined range relative to the support beam 10 under the force, that is, the main mast 11 can be stably suspended on the support beam 10 by the suspension method, and the main mast 11 is not completely fixed on the support beam 10 in the vertical direction, and the main mast 11 can move relative to the support beam 10. Among them, the main mast 11 is suspended from the support beam 10 by means of the hanging ear 8.

[0029] In the embodiment of the present application, the rapping device includes a driving component (not shown in the figure), a transmission component and a rapping component 31 . The driving component drives the rapping component 31 to move through the transmission component to apply an upward rapping force to the main mast 11 .

[0030] The driving component can be a hydraulic cylinder or a motor. The main function of the transmission component is to transfer the kinetic energy of the driving component to the rapping component. The rapping component 31 mainly contacts the main mast 11 to transmit force. The rapping component and the main mast 11 can be in rigid contact.

[0031] In the present application, the main frame is suspended on the support beam 10 through the main mast 11, and the main mast 11 can move upward relative to the support beam 10. In this way, when the rapping component applies an upward force to the main mast 11, the main mast 11 moves upward relative to the support beam 10, and thus does not generate reaction forces from other structures except the main frame's own gravity. In this way, the rapping force and rapping acceleration acting on the cathode frame are not easy to attenuate, thereby improving the dust removal efficiency of the cathode line, being able to effectively remove dust from the cathode line, thereby improving the dust removal efficiency of the electrostatic precipitator, and enabling the electrostatic precipitator to operate efficiently and stably for a long time.

[0032] Moreover, the rapping device in the embodiment of the present application has a simple structure and is easy to manufacture and install. It can greatly reduce the length of the shell and the cost of the steel structure, shorten the length of the shell, and reduce the electric field layout space of the electrostatic precipitator.

[0033] Among them, the magnitude of the rapping force can be determined according to the specific use environment.

[0034] In a specific embodiment, the transmission component includes a crank 3, which is fixed on a rotating shaft P and can rotate. The rotating shaft P is also supported by the external environment, and the rotating shaft can be supported by the external environment by bearings and other components. The crank 3 includes an integral first section 33 and a second section 34 at a certain angle. The end of the first section 33 away from the rotating shaft is connected to the driving component, and the rapping component is arranged at the end of the second section 34 away from the rotating shaft. The rapping component can be an integral structure with the second section 34, and of course, it can also be a separate structure with the second section 34, and the two are installed and fixed by mechanical components.

[0035] In the embodiment of the present application, the crank 3 can achieve a change in the force direction, thereby improving the flexibility of the arrangement of components such as drive components and transmission components.

[0036] In a specific embodiment, the end of the first section 33 away from the rotating shaft is a horizontal section 32. That is, the force applied by the driving component to the first section 33 is a horizontal force, and the crank 3 can convert the horizontal force F' into a vertical upward force F.

[0037] In a specific embodiment, the transmission component also includes a rapping hammer 2, and the rapping hammer 2 includes a hammer handle 21 and a hammer head 22. The driving component is connected to the hammer handle 21. When the driving component drives the hammer handle 21 to move in a circle, the hammer head 22 rotates relative to the connection position of the hammer handle 21 and applies a horizontal force to the crank through the hammer head 22, and the horizontal force is converted into a vertical upward force through the crank. Depending on the working conditions, different crank 3 forms and structures, and rapping hammers 2 of different sizes can be set to provide different rapping forces.

[0038] The hammer handle 21 may be a curved structure to enable the hammer head 22 to apply a horizontal force. The curved shape of the hammer handle 21 may be reasonably set according to the technical effect to be achieved. The specific setting parameters of the hammer handle 21 are not disclosed herein and do not hinder the understanding and implementation of the technical solution of the present application by those skilled in the art.

[0039] The hammer handle 21 can be directly connected to the driving component, and of course, it can also be connected to the driving component through an intermediate component, for example, through a rotating shaft, a bearing 1 and other components to achieve connection with the output end of the driving component.

[0040] In the embodiment of the present application, the cathode frame further comprises a second reinforcing plate 9, which is fixed to the suspension position of the main mast 11. The second reinforcing plate 9 can improve the connection strength of the suspension position of the main mast 11 to a certain extent.

[0041] In the embodiment of the present application, the main mast 11 has a first rod section 111 located above the suspension point, and the rapping device further includes a sleeve 4, which can be fixed to the first rod section by bolts 7, and there is no need to weld the sleeve 4 and the first rod section, so as to prevent stress concentration from damaging the cathode frame main mast 11. A rapping body 6 is fixed to the sleeve 4, and the rapping component cooperates with the rapping body 6 to abut against it.

[0042] Similarly, the rapping body 6 is a rigid collision rapping body formed of a rigid material. The rapping body 6 can be a component such as rubber.

[0043] In each embodiment of the present application, the rapping device further includes a first reinforcing plate 5, which is fixed to the first rod segment and is located on the rapping body of the sleeve. The first reinforcing plate 5 can play a reinforcing role and prevent the rapping body 6 from being continuously subjected to the axial upward rapping force and moving during the rapping process.
