[0002] The installation position of traditional fixed oil fume purifiers is greatly restricted and cannot be flexibly adjusted according to the actual situation of the use place. For specific places that need to handle the oil fume generated by the combustion of biomass fuels such as straw, such as agricultural production areas and biomass energy utilization factories, fixed oil fume purifiers often cannot meet the requirements of flexibility and mobility. At the same time, a large amount of oil fume and combustion residues will be generated during the combustion of biomass fuels such as straw. These substances are extremely easy to adhere to the smoke suction hood of the oil fume purifier, seriously affecting the air suction effect and oil fume purification ability of the oil fume purifier. Over time, the adhesions on the smoke suction hood will gradually increase, not only increasing the cleaning difficulty, but also possibly damaging the service life of the oil fume purifier. For this reason, we propose a mobile electrostatic oil fume purifier. Content of the Utility Model

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] The following will detail the technical solutions provided by each embodiment of the present utility model in conjunction with the drawings.

[0024] Please refer to Figures 1-8, An embodiment provided by the present utility model: A mobile electrostatic oil fume purifier, including a mobile platform 100, on which an electrostatic oil fume purifier body 101 is installed. At both ends of the electrostatic oil fume purifier body 101, there are a smoke inlet 107 and a smoke outlet 108. A centrifugal fan 102 connected to the smoke outlet 108 is connected to the mobile platform 100. A generator 103 and an electric control box 104 are provided on the mobile platform 100. The generator 103 and the electric control box 104 are used to supply power to the electrostatic oil fume purifier body 101 and the centrifugal fan 102. A transformer 109 is installed on the mobile platform 100, and the transformer 109 is electrically connected to the electrostatic oil fume purifier body 101. A hoisting component 200 is connected to the mobile platform 100. The output end of the hoisting component 200 is connected to a smoke suction hood 106. A telescopic hose 105 is connected between the smoke suction hood 106 and the smoke inlet 107 of the electrostatic oil fume purifier body 101. The output end of the hoisting component 200 can drive the smoke suction hood 106 to lift and rotate. A vibration unit is provided in the hoisting component 200. When the smoke suction hood 106 rotates and lifts, the vibration unit can drive the smoke suction hood 106 to vibrate.

[0025] Adopting the solution of the present utility model, the generator 103 is responsible for providing power. The electrostatic oil fume purifier body 101 and the centrifugal fan 102 are supplied with power and controlled through the electric control box 104. The electric control box 104 is used to ensure stable power supply. When the device is turned on, the required high-voltage static electricity is provided to the electrostatic oil fume purifier body 101 through the transformer 109. A static electric field is formed inside the electrostatic oil fume purifier body 101. When the oil fume enters through the smoke inlet 107, the particulate matter in the oil fume is attracted and adsorbed on the static electricity paper under the action of the static electric field, thus realizing the purification of the oil fume. The static electricity oil fume purification technology is a relatively mature existing design at present and will not be elaborated here. The innovative solution of the present utility model lies in that the mobile platform 100 endows the device with high mobility and can be conveniently moved to different working places. At the same time, a hoisting component 200 is installed on the mobile platform 100, and the smoke suction hood 106 and the smoke inlet 107 of the electrostatic oil fume purifier body 101 are connected through the telescopic hose 105. The hoisting component 200 can drive the smoke suction hood 106 to lift and rotate and can move along the sintered straw, thus realizing the purpose of flue gas purification. A vibration unit is provided in the hoisting component 200. When the smoke suction hood 106 rotates and lifts, the vibration unit will cause the smoke suction hood 106 to vibrate, so that impurities such as burned straw particles adhered to the smoke suction hood 106 will fall off automatically, keeping the smoke suction hood 106 clean and working efficiently.

[0026] In one embodiment, the crane assembly 200 includes a mounting panel 201 for mounting on the mobile platform 100. A drive box 203 is provided on the mounting panel 201. Four symmetric second slide bars 224 are provided at the top of the drive box 203. The drive box 203 is connected to a lifting column 204 through the four second slide bars 224. A first drive unit for driving the lifting column 204 to lift is provided on the drive box 203. A transfer frame 205 is provided at the top of the lifting column 204. A swing arm 209 is connected to the top of the transfer frame 205. A second drive unit for driving the swing arm 209 to rotate is provided inside the transfer frame 205. A connecting rod assembly is connected to the bottom of the swing arm 209. The lower end of the connecting rod assembly is connected to a smoke hood connecting frame 219 for connecting the smoke hood 106. A fourth protrusion 223 is provided on the side wall of the mounting panel 201. A connecting plate 220 is detachably connected to the smoke hood 106. A third protrusion 221 matching the fourth protrusion 223 is provided on the connecting plate 220. Vibration is generated when the third protrusion 221 and the fourth protrusion 223 move alternately.

[0027] Adopting the solution of the present utility model, when the first drive unit in the drive box 203 is started, the lifting column 204 moves up and down along the direction of the second slide bar 224. The up and down movement of the lifting column 204 will drive the transfer frame 205 and the swing arm 209 connected to its top. The second drive unit inside the transfer frame 205 can drive the swing arm 209 to rotate synchronously or progressively. The rotation of the swing arm 209 is transmitted to the smoke hood connecting frame 219 through the connecting rod assembly, so that the smoke hood 106 rotates horizontally to adapt to the positions of different oil fume sources. During the up and down movement of the lifting column 204, the fourth protrusion 223 on the side wall of the mounting panel 201 and the third protrusion 221 on the connecting plate 220 of the smoke hood 106 move alternately, so that the smoke hood 106 generates vibration, which helps the impurities such as burned straw particles adhering to the smoke hood 106 to fall off automatically, thus automatically cleaning the impurities on the smoke hood 106, reducing the frequency and cost of manual maintenance, and improving the continuous working ability of the equipment.

[0028] In one embodiment, a support platform 206 for supporting the rotation of the swing arm 209 is connected to the top of the transfer frame 205. A first protrusion 207 is provided on the top surface of the support platform 206. A second protrusion 210 matching the first protrusion 207 is provided at the bottom of the swing arm 209. Vibration is generated when the first protrusion 207 and the second protrusion 210 move alternately.

[0029] With the solution of the present utility model, a support platform 206 is connected to the top of the transfer rack 205. The support platform 206 is used to stabilize and support the rotational movement of the rocker arm 209. A first protrusion 207 is provided on the top surface of the support platform 206. The first protrusion 207 is composed of a plurality of rubber semi-cylindrical protrusions arranged in a circular pattern. A second protrusion 210 that cooperates with the first protrusion 207 is provided at the bottom of the rocker arm 209. As the rocker arm 209 rotates, the second protrusion 210 will have an interleaved movement with the first protrusion 207, resulting in a brief separation and re-contact when they touch, thereby causing vibration.

[0030] In one embodiment, the link assembly includes a first link 211 and a second link 214. The top of the first link 211 is connected to the rocker arm 209. The second link 214 is connected to the bottom of the first link 211. The smoking hood connecting frame 219 is connected to the bottom of the second link 214. An expansion and vibration part is provided between the first link 211 and the second link 214. When the first link 211 and the second link 214 approach or move away from each other, they can transmit the vibration to the smoking hood 106.

[0031] With the solution of the present utility model, between the first link 211 and the second link 214, there is an expansion and vibration part. The expansion and vibration part can generate vibration when the two links approach or move away from each other. As the first driving unit drives the lifting column 204 to rise or fall, the relative position between the first link 211 and the second link 214 will change, thereby triggering the expansion and vibration part to generate vibration. The vibration is transmitted through the link assembly and finally reaches the smoking hood connecting frame 219 connected to the bottom of the second link 214, and then acts on the smoking hood 106.

[0032] In one embodiment, the expansion and vibration part includes a first baffle 212 installed at the bottom of the first link 211. A second baffle 2121 is connected to the top of the second link 214. A chute 213 is provided at the center position of the bottom of the first link 211. A first slide bar 215 that slides in the chute 213 is connected to the top of the second baffle 2121. A plurality of support rods 217 are connected to the top of the second baffle 2121. The plurality of support rods 217 are slidably connected to the first baffle 212. A spring 218 is sleeved on each support rod 217. The two ends of the spring 218 are respectively abutted against the first baffle 212 and the second baffle 2121. A fifth protrusion 216 is provided on the outer side of the first slide bar 215. When the fifth protrusion 216 and the port of the chute 213 have an interleaved movement, the first slide bar 215 generates vibration.

[0033] According to the solution of the utility model, when the first connecting rod 211 and the second connecting rod 214 move closer to or farther from each other, the first baffle 212 and the second baffle 2121 move accordingly. Specifically, when the first connecting rod 211 and the second connecting rod 214 move relative to each other, the first slide bar 215 on the second baffle 2121 slides in the slide slot 213. During the sliding process, the fifth protrusion 216 moves alternately with the port of the slide slot 213, so that the first slide bar 215 is subjected to a sudden change in resistance, thereby causing vibration. A plurality of support rods 217 are slidably connected with the first baffle 212, and a spring 218 is sleeved on the support rod 217. When the first connecting rod 211 and the second connecting rod 214 move relative to each other, the spring 218 is compressed or stretched, storing or releasing energy, which also helps to enhance the generation and reset of vibration. The energy is transmitted to the smoke hood connecting frame 219 and the smoke hood 106 through the connecting rod assembly to help clean the oil smoke particles or other impurities attached to the smoke hood 106.

[0034] Optionally, the first driving unit includes a first motor 222 installed in the driving box 203, the output end of the first motor 222 is connected to a screw 225, the screw 225 is connected to the top wall of the driving box 203 through a bearing, and a screw hole matching the screw 225 is provided at the center of the lifting column 204.

[0035] Optionally, the second driving unit includes a second motor 208 installed in the intermediate rotating frame 205 , and an output end of the second motor 208 is connected to the rocker arm 209 .

[0036] The utility model is designed with a mobile platform 100, which can be easily moved to different workplaces without the need for fixed installation, greatly improving the flexibility and scope of use of the equipment. Combined with the electrostatic fume purification technology, the high-voltage electrostatic field formed inside the electrostatic fume hood body 101 can effectively adsorb and remove particulate matter in the fume, thereby achieving an efficient fume purification effect. At the same time, a vibration unit is provided in the crane assembly 200. When the fume hood 106 is rotating and lifting, the vibration unit will cause it to vibrate, automatically falling off impurities such as burned straw particles adhering to the fume hood 106, thereby maintaining the cleanliness of the fume hood 106 and ensuring the continuous and efficient operation of the equipment.
