Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas purification technology, specifically a mobile electrostatic range hood suction hood. Background Technology
[0002] With increasingly stringent environmental protection requirements, the effective treatment of flue gas generated during straw burning has become an urgent environmental issue. Burning straw produces large amounts of dust particles and other harmful substances. If these substances are released directly into the environment without effective treatment, they will not only severely impact air quality but also pose a potential threat to human health.
[0003] In flue gas treatment systems for straw combustion, the suction hood is a key component for capturing and collecting flue gas, and its design and performance directly affect the efficiency of the entire system. However, traditional suction hoods currently have certain problems with filtration efficiency. Because the flue gas produced by straw combustion contains a large number of dust particles, these particles easily adhere to the filter plates when passing through the suction hood's filtration system, leading to decreased filtration efficiency and even filter plate blockage, thus affecting the normal operation of the entire flue gas treatment system. Currently, cleaning is mostly done manually, which cannot self-clean fine dust particles. Therefore, we propose a mobile electrostatic range hood suction hood. Utility Model Content

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0029] Please see Figures 1-9 This utility model provides an embodiment of a portable electrostatic range hood hood, comprising a hood body 100, which is a hollow structure. A suction pipe 102 is connected to the top of the hood body 100, and a flange connector 101 is connected to the top of the suction pipe 102. A first filter plate 103 is detachably connected to the bottom of the hood body 100, and a second filter plate 200 is elastically connected to the inner side of the bottom of the hood body 100, located above the first filter plate 103. Slide grooves 105 are provided on both side walls of the hood body 100. Connecting rods 202, corresponding in number to the slide grooves 105, are connected to the sides of the second filter plate 200. The connecting rods 202 are slidably disposed within the slide grooves 105, and their extension ends pass through the side walls of the hood body 100 and are connected to a vibration unit. An elastic component is provided on the inner wall of the hood body 100, and the output end of the elastic component is connected to the second filter plate 200.
[0030] In this invention, when the flue gas treatment system is started, the suction pipe 102 in the system is connected to the suction pipe 102 via the flange connector 101, thereby providing negative pressure suction to the suction hood body 100. At this time, as the device moves on the surface of the straw, it draws the flue gas generated by the burning straw into the suction hood body 100. The flue gas first passes through the first filter plate 103, which is used to initially filter large particles in the flue gas, reducing the difficulty of subsequent treatment. Small particles in the flue gas are filtered through the second filter plate 200. The up-and-down movement of the hood body 100, through an external vibration unit, enables the connecting rod 202 on the second filter plate 200 to slide within the slide groove 105, thereby causing the second filter plate 200 to vibrate. This vibration can effectively remove the particulate matter adsorbed on the second filter plate 200 and maintain its filtration effect. This utility model mainly improves the internal structure of the hood body 100. Its matching flue gas treatment system mainly treats the flue gas generated during straw burning, including but not limited to using high-voltage electrostatic flue gas treatment technology to treat the flue gas.
[0031] Meanwhile, in this utility model, the elastic component is located on the inner wall of the suction hood body 100, and its output end is connected to the second filter plate 200. When the second filter plate 200 is subjected to vibration or external force, the elastic component can provide a certain buffering and reset function to ensure the stability and filtration effect of the second filter plate 200. Moreover, no manual intervention is required, which reduces maintenance costs and workload.
[0032] Alternatively, in one embodiment, the porosity of the first filter plate 103 is greater than that of the second filter plate 200. Specifically, the first filter plate 103 is provided with multiple sets of elongated through grooves 104, and the second filter plate 200 is provided with multiple through holes 201.
[0033] In one embodiment, the vibration unit includes a dust-blocking component 203 connected to the extension end of the connecting rod 202. The dust-blocking component 203 is close to but does not contact the side wall of the suction hood body 100. There are four sliding grooves 105, which are symmetrically arranged on both sides of the suction hood body 100. There are also four dust-blocking components 203 located at the sliding grooves 105. Elastic plates 204 are connected to the two dust-blocking components 203 symmetrically located on both sides of the suction hood body 100. The unit also includes a connecting frame 207, with a connecting rod assembly 205 at the bottom of the connecting frame 207. The connecting rod assembly 205 is detachably connected to the two elastic plates 204. A vibration source is provided to drive the connecting frame 207 to vibrate.
[0034] In this design, four dust-blocking components 203 are respectively connected to the extension ends of four connecting rods 202, located on both sides of the suction hood body 100, close to but not in contact with the side wall of the suction hood body 100. The advantage of this arrangement is that with the slight vibration of the second filter plate 200, dust can be prevented from entering the suction hood body 100 through the slide 105. When the vibration source is activated, the generated vibration force acts on the connecting frame 207, thereby driving the second filter plate 200 to vibrate. The vibration source can be an electromagnetic vibrator, for example, the electromagnetic vibrator can be installed on the connecting frame 207, or the convex contact vibration in this design can be used.
[0035] In one embodiment, the vibration source is an external device. A drive plate 209 is connected to the connecting frame 207. The drive plate 209 vibrates by contacting the external drive unit during movement. A support plate 208 is connected between the connecting frame 207 and the drive plate 209. The contact surface between the drive plate 209 and the drive unit is a convex contact. When the drive plate 209 moves alternately relative to the external drive unit, vibration is generated through the convex contact.
[0036] In this design, before the suction hood begins operation, the vibration-damping plate 209 on the connecting frame 207 is stationary, maintaining a certain distance from the external vibration-damping unit. The surface of the vibration-damping plate 209 is designed with multiple protrusions for contacting the vibration-damping unit. When the suction hood body 100 performs suction, the vibration-damping plate 209, its connected connecting frame 207, and the second filter plate 200 remain stationary and do not participate in the vibration process. When the suction hood body 100 completes the suction process and moves upwards for storage, the connecting frame 207 and the vibration-damping plate 209 move accordingly, and the protrusions on the vibration-damping plate 209 begin to contact the vibration-damping unit. As the suction hood body 100 continues to rise, the vibration drive plate 209 moves alternately relative to the vibration drive unit, causing the protrusions on the vibration drive plate 209 to intermittently contact and separate from the corresponding points on the vibration drive unit. Whenever the protrusions contact the vibration drive unit, a brief vibration is generated due to the friction and impact between the two, and is transmitted to the second filter plate 200 through the connecting frame 207, thereby causing the entire second filter plate 200 to vibrate. Through the vibration of the second filter plate 200, the particulate matter and dust adsorbed on its surface are effectively removed, thus ensuring the continuous filtration effect of the filter plate.
[0037] Alternatively, in one embodiment, the elastic component includes two support plates 211 installed inside the suction hood body 100, with a slide rod 212 connected between the two support plates 211. The second filter plate 200 is provided with a first sliding hole 210 for the slide rod 212 to slide. A first spring 213 and a second spring 214 are sleeved on the slide rod 212. The two ends of the first spring 213 abut against the top surfaces of the upper support plate 211 and the second filter plate 200, respectively, and the two ends of the second spring 214 abut against the bottom surfaces of the lower support plate 211 and the second filter plate 200, respectively.
[0038] Alternatively, in one embodiment, a sliding box 215 is installed at the bottom of the second filter plate 200. The sliding box 215 has a hollow structure, and the support plate 211 below is slidably connected inside the sliding box 215. A second sliding hole 216 is opened on the first filter plate 103, and the sliding box 215 is slidably connected inside the second sliding hole 216.
[0039] To reduce the frictional force of the second filter plate 200, in one embodiment, each connecting rod 202 is rotatably connected to a roller 217, the dust baffle 203 is provided with a cavity corresponding to the roller 217, and the roller 217 is rotatably connected to the two side walls of the suction hood body 100.
[0040] This utility model employs a dual filtration system, including a first filter plate 103 and a second filter plate 200. The first filter plate 103 can effectively filter large particles in the flue gas initially, reducing the difficulty of subsequent treatment, while the second filter plate 200 further filters small particles in the flue gas, improving the purification effect. Through the design of an external vibration unit and a connecting rod 202, the second filter plate 200 can achieve automatic dust removal. As the suction hood body 100 moves up and down, the second filter plate 200 vibrates, thereby effectively removing the adsorbed particles, maintaining its filtration effect, reducing maintenance costs and workload, and ensuring the continuous and efficient operation of the suction hood.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.
