Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, and particularly relates to a toner purification device. Background Art

[0002] At present, the vast majority of generator sets adopt brush excitation. A large amount of conductive dust - toner is generated due to the friction between the slip ring and the brush holder. These toner particles will be blown outside the generator set by the cooling air output from the outlet of the slip ring brush holder. Furthermore, this poses a safety hazard to the operation of the generator set. In severe cases, it will cause a short circuit of the electrical equipment outside the generator set, reduce the insulation resistance of the rotor of the generator set, lead to an increase in the temperature of the rotor, and cause a serious accident of burning out the generator set, thus causing huge economic losses to the power plant.

[0048] The following will make a detailed description of the above components respectively.

[0049] The filtering channel includes: a blowing component 1 and a filtering component 2. The filtering channel is suitable for filtering the cooling air output from the outlet of the slip ring brush holder.

[0050] Among them, seeFigure 2 and in combination with Figure 1 As shown, in this embodiment, the air supply assembly 1 includes: an air inlet duct 11, an emergency part, and an air distribution part 14.

[0051] The first end face of the air inlet duct 11 is connected to the outlet of the slip ring brush holder, and the second end face of the air inlet duct 11 is connected to the filter assembly 2 through the air distribution part 14. The air distribution part 14 is adapted to disperse the cooling air output from the air inlet duct 11 and then output it to the filter assembly 2. The emergency part is arranged on the air inlet duct 11, and the emergency part is adapted to directly discharge the cooling air in the air inlet duct 11 into the external air when in the open state. The first end face of the air inlet duct 11 is the end face close to the outlet of the slip ring brush holder, and the second end face of the air inlet duct 11 is the end face close to the air distribution part 14.

[0052] Further, the air inlet duct 11 includes: a first duct 111 and a second duct 112. The first duct 111 is connected to the air distribution part 14 through the second duct 112. The first end face of the air inlet duct 11 is the first end face 1111 of the first duct, and the second end face of the air inlet duct 11 is the first end face of the second duct 112. The emergency part is arranged on the first duct 111.

[0053] The first duct 111 and the second duct 112 are hermetically connected, and the second duct 112 and the air distribution part 14 are hermetically connected, so that when the emergency part is in the closed state, the inside of the air supply assembly 1 is in a relatively sealed state, and the cooling air will not leak into the external air when passing through the air supply assembly 1. That is, when the toner purification device 00 is operating normally, the toner in the cooling air will not leak into the external air, ensuring the high efficiency, safety, and cleaning power of the toner purification device 00.

[0054] In this embodiment, the second duct 112 can be made of a rigid material and will not deform, which can better guide the cooling air to flow in the second duct 112, making the structure of the toner purification device 00 more stable. It should be noted that the specific structure and material of the second duct 112 in this application are not limited, and it can also be a plastic hose or other components, which can be reasonably selected and set according to actual needs, as long as it can achieve the purpose of allowing the cooling air to be input into the air distribution part 14 after passing through the second duct 112.

[0055] More specifically, referring to Figure 3 and in combination with Figure 4As shown in the figure, the emergency department includes: an automatic exhaust member 12 and an emergency exhaust member 13. The automatic exhaust member 12 is provided on the second end face 1112 of the first air duct. The second end face 1112 of the first air duct is disposed opposite to the first end face 1111 of the first air duct, that is, the second end face 1112 and the first end face 1111 of the first air duct are two parallel end faces.

[0056] The automatic exhaust member 12 includes: an automatic exhaust door, a first driving member, and a sliding member. The automatic exhaust door is embedded on the second end face 1112 of the first air duct. The automatic exhaust door is adapted to discharge the cooling air in the first air duct 111 into the external air through the automatic exhaust door. In this embodiment, the automatic exhaust door can be a metal mesh, and the metal mesh has a plurality of exhaust holes. The present application does not limit the specific structure of the exhaust holes of the automatic exhaust door. The exhaust holes can be circular, square, diamond-shaped or other shapes, as long as the cooling air entering the first air duct 111 can be discharged into the external air through the automatic exhaust door.

[0057] The first driving member is connected to the sliding member. The sliding member is in contact with the second end face 1112 of the first air duct. Based on the drive of the first driving member, the sliding member can move along the surface of the automatic exhaust door, so that the automatic exhaust member 12 enters an open state or a closed state. When the automatic exhaust member 12 is in the open state, the sliding member does not overlap with the automatic exhaust door, and the cooling air can be discharged into the external air through the exhaust holes of the automatic exhaust door. When the automatic exhaust member 12 is in the closed state, the sliding member overlaps with the automatic exhaust door, and the cooling air cannot be discharged into the external air through the automatic exhaust door.

[0058] The first driving member can be realized by an electric push rod, and the electric push rod is common knowledge well known to those skilled in the art and will not be elaborated here. It should be noted that the present application does not limit the specific structure and position of the first driving member. The first driving member can be provided inside the first air duct 111 or outside the first air duct 111. The first driving member can also be a multi-link structure, which can be reasonably selected and set according to actual needs, as long as it can achieve the purpose of driving the automatic exhaust member 12 to enter an open state or a closed state.

[0059] In addition, the emergency exhaust member 13 is provided on the third end face 1113 of the first air duct. The second end face 1112 of the first air duct is adjacent to the third end face 1113 of the first air duct, that is, the second end face 1112 and the third end face 1113 of the first air duct are two adjacent end faces. The emergency exhaust member 13 includes: an emergency exhaust door and a second driving member.

[0060] The emergency exhaust door is connected to the second driving member, and the second driving member is adapted to drive the emergency exhaust door into an open state or a closed state. When the emergency exhaust door is in the open state, the cooling air in the first air duct 111 is directly discharged into the external air through the emergency exhaust door.

[0061] In this embodiment, the second driving member can be a handle, and a person can open and close the emergency exhaust door by contacting the handle. The present application does not limit the specific structure of the second driving member. It can be electrically controlled by the control component 3 and can be reasonably selected and set according to actual needs, as long as it can achieve the purpose of driving the emergency exhaust door into an open state or a closed state. Moreover, the present application does not limit the specific structure of the emergency exhaust door, which can be reasonably selected and set according to actual needs, as long as it can achieve the purpose of directly discharging the cooling air in the first air duct 111 into the external air through the emergency exhaust door.

[0062] The cooling air directly discharged into the external air through the automatic exhaust member 12 and the emergency exhaust member 13 in the emergency department can be filtered by an external filter to reduce the random discharge of toner.

[0063] In addition, referring to Figure 5 As shown, the air distribution member 14 includes: a housing 141 and an air distribution net 142. The first end face of the housing 141 communicates with the first end face of the second air duct 112, the second end face of the housing 141 communicates with the filter assembly 2, the first end face and the second end face of the housing 141 are oppositely arranged, that is, the first end face and the second end face of the housing 141 are two opposite end faces. The air distribution net 142 is arranged between the first end face and the second end face of the housing 141, and the air distribution net 142 is arranged parallel to the first end face of the housing 141. The air distribution net 142 is hung on the first end face of the housing 141 through a connecting rod, or can also be supported on the lower filter box 21 through a connecting rod, and can be reasonably selected and set according to needs.

[0064] In this embodiment, the air distribution net 142 can be a metal plate with a plurality of small holes. In order to enable the filter group 24 below the air distribution net 142 to filter the cooling air, the aperture of the small hole at the center of the air distribution net 142 is smaller, and the aperture of the small holes extending from the center to the periphery gradually increases. The air distribution net 142 can also be set as a cuboid with one end face open. The open end face is connected to the second air duct 112, and the other end face opposite to the open end face has small holes with a small aperture. From the filter group 24 to the direction of the second air duct 112 around the air distribution net 142, the aperture of the small holes gradually becomes larger, so that the cooling air output from the air inlet air duct 11 is scattered by the air distribution member 14, and the scattered cooling air enters the filter group 24 for filtering.

[0065] Further, referring to Figure 1 , Figure 6 , Figure 7 , Figure 8 and in combination with Figure 9 as shown, the filtering assembly 2 is adapted to filter the cooling air fed into it. In this embodiment, the filtering assembly 2 is mainly used to filter toner in the cooling air. The filtering assembly 2 includes: a filtering box 21 and a filtering group 24. The filtering group 24 is disposed in the filtering box 21. The air inlet of the filtering box 21 is communicated with the air distributing member 14, and the outlet of the filtering box 21 is communicated with the air inlet of the driving assembly 4.

[0066] The filtering assembly 2 further includes: a moving cart 22, slide rails and a filtering door. The filtering group 24 is disposed on the moving cart 22. The filtering door is disposed on the side surface of the filtering box 21. The moving cart 22 includes: a vehicle body and moving wheels. The moving wheels are connected to the lower end surface of the vehicle body, and there are four moving wheels. The slide rails are fixedly disposed inside the filtering box 21 and are connected to the lower end surface of the filtering box 21. The slide rails are adapted to assist the moving cart 22 to move into or out of the filtering box 21, and there are two groups of slide rails.

[0067] Two limit blocks are provided on each group of slide rails. Among them, the first limit block is fixedly disposed at the first end of the slide rail and is adapted to limit the position of the moving cart 22. The second limit block is flipably disposed at the second end of the slide rail. The second limit block is connected to the slide rail, and the second limit block has an inclined surface. The first end of the slide rail is the end far from the filtering door, and the second end of the slide rail is the end close to the filtering door. The filtering door has a handle, and the opening or closing of the filtering door can also be driven electrically, and reasonable selection and setting can be made according to requirements.

[0068] When the moving cart 22 is about to move into or out of the filtering box 21, after opening the filtering door, the second limit block is folded in a direction away from the first limit block. The inclined surface connects the ground and the slide rail, so that the moving cart 22 can move onto the slide rail through the inclined surface of the second limit block. When the moving cart 22 moves into the filtering box 21, the second limit block is folded in a direction towards the first limit block. The first end of the second limit block abuts against the moving cart 22, and the filtering door is closed. The second end of the second limit block abuts against the filtering door. Through the cooperation of the second limit block and the first limit block, the position of the moving cart 22 can be jointly limited, making the filtering work of the filtering assembly 2 more stable and improving the filtering performance of the toner purification device 00.

[0069] The filtering group 24 includes: a plurality of filtering elements 242 and a fixing frame 241. The arrangement of the plurality of filtering elements 242 is a matrix structure. The plurality of filtering elements 242 are all arranged in parallel along the first direction, and the distance between the plurality of filtering elements 242 is equal. The first direction is Figure 7 the direction shown by X in

[0070] The fixing frame 241 has a plurality of clamping holes, and the first ends of the plurality of filter elements 242 each have a clamping groove 2421. The plurality of clamping holes correspond to the plurality of filter elements 242, which means that the number and position of the plurality of clamping holes correspond one by one to the plurality of filter elements 242.

[0071] An interface is sleeved inside each of the plurality of filter elements 242. The structure of the interface is the same as that of the clamping groove 2421. Through the setting of the interface, the connection between the plurality of filter elements 242 and the fixing frame 241 can be made more stable. The fixing frame 241 is sleeved on the outer walls of the plurality of filter elements 242 through the plurality of clamping holes.

[0072] Meanwhile, in order to ensure that the filter group 24 will not be adsorbed to the air outlet 25 of the filter assembly 2 during operation, thereby blocking the air outlet 25 of the filter assembly 2 and affecting the normal operation of the toner purification device 00, a plurality of load-bearing members are provided on each of the plurality of filter elements 242. The load-bearing members can be arranged at the second ends or on the sides of the plurality of filter elements 242, and can keep a certain distance between the plurality of filter elements 242 and the air outlet 25 of the filter assembly 2 during the operation of the toner purification device 00, ensuring the safe operation of the toner purification device 00.

[0073] The fixing frame 241 is connected to the moving cart 22, and the fixing frame 241 is sleeved on the outer walls of the plurality of filter elements 242. To ensure the stability of the plurality of filter elements 242, a plurality of fixing frames 241 can be provided. In addition, the fixing frame 241 has a handle, which is suitable for the staff to push the moving cart 22. In this embodiment, the plurality of filter elements 242 are made of polyester needle punched felt, with a thickness of (1.7 ± 10%) mm and an air permeability of (10 ± 20%) m 3 / m 2 / min.

[0074] The plurality of filter elements 242 can all be cylindrical. The first ends of the plurality of filter elements 242 are all open, which is suitable for the entry of cooling air. The second ends of the plurality of filter elements 242 are closed, which can prevent the toner in the cooling air from leaking out. The first ends of the plurality of filter elements 242 are the ends close to the air distribution member 14, and the second ends of the plurality of filter elements 242 are the ends far from the air distribution member 14. The filtered cooling air is discharged into the space below the filter group 24 through the plurality of filter elements 242, and through the outlet of the filter box 21, and the filtered cooling air is discharged into the external air through the air outlet 42 of the fan 41 and the driving assembly 4. By arranging the plurality of filter elements 242 in a matrix structure, the resistance can be reduced, the maintenance can be facilitated, the dust capacity can be increased, the noise can be reduced, and the filtering efficiency of the toner purification device 00 can be improved.

[0075] When multiple filter elements 242 need to be cleaned, the cleaning method is as follows: Go to a designated outdoor place and clean them with dry compressed air or a handheld ash blower, and repeatedly tap the multiple filter elements 242. It is strictly prohibited to wash them with water or other detergents to prevent the multiple filter elements 242 from caking, which will affect the ventilation volume. Since the dust contains conductive dust, a vacuum cleaner cannot be used for cleaning.

[0076] The filter assembly 2 further includes: a seal 23. The seal 23 is provided at the air inlet end of the filter box 21 inside the filter box 21. The seal 23 includes: a third driving member 231, a flexible seal cover 232, a first support member 233, and a second support member 234.

[0077] The third driving member 231 is fixed on the air distribution member 14, the output end of the third driving member 231 is connected to the second support member 234, the first end of the flexible seal cover 232 is connected to the first support member 233, the first support member 233 is fixedly connected to the filter box 21, and the second end of the flexible seal cover 232 is connected to the second support member 234.
