[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] Embodiment: A fume cleaning and purification device for an oil fume pipeline, such as Figure 1 - Figure 4 As shown, it includes a mounting frame 2, on which a plurality of driving members 24 are fixedly mounted, and the plurality of driving members 24 are used to drive the mounting frame 2 to move up and down inside the pipeline 1; Two groups of scraper groups 3 are arranged below the mounting frame 2 at intervals to form a rectangle, and are used to scrape off the grease attached to the inner wall of the pipe 1. Each group of scraper groups 3 includes two horizontal blade racks 31 and two inclined blade racks 32. The two inclined blade racks 32 are rotatably connected to each other. The two horizontal blade racks 31 are respectively located at both ends of the two inclined blade racks 32 and are rotatably connected. The horizontal blade racks 31 and the inclined blade racks 32 are both provided with scrapers 321. The adjustment component 4 is fixedly mounted below the mounting frame 2 and is used to adjust the two scraper groups 3 to move closer to or farther away from each other.

[0023] In the present invention, a driving member 24 is provided above the mounting frame 2 and a scraper group 3 is provided below the mounting frame 2. During use, a gap is first opened at the top of the vertically mounted pipe 1 and the device is placed into the pipe 1. Then, the two scraper groups 3 are driven away from each other by the adjusting component 4, so that the scrapers 321 on the horizontal tool holder 31 and the inclined tool holder 32 are against the side walls around the pipe 1. Then, the mounting frame 2 is driven downward as a whole by the driving member 24, so that the scraper 321 scrapes off the grease and smoke on the side walls of the pipe 1, thereby quickly and efficiently completing the cleaning of the vertical fume pipe 1.

[0024] It should be noted that in actual use, a traction rope can be installed above the mounting frame 2 as needed to more stably control the descending movement of the mounting frame 2. Moreover, since the mounting frame 2 has its own weight, during the descent of the mounting frame 2, the driving member 24 can more labor-savingly scrape off the grease and smoke on the side wall of the pipe 1. The inner wall of the oil fume pipe can be thoroughly cleaned by scraping multiple times.

[0025] It should be noted that the driving member 24 includes a driving motor and a roller, and the roller is installed around the mounting frame 2. During use, the driving motor can be controlled to drive the roller to move downward along the inner wall of the pipe 1, so that the scraper group 3 under the mounting frame 2 is against the side wall of the pipe 1 to scrape off grease and smoke. The driving motor and the roller are conventional driving means in the prior art and will not be repeated here.

[0026] Furthermore, if Figure 4As shown, the adjustment assembly 4 includes a support plate 41 fixedly mounted below the mounting frame 2, guide bevel grooves 4101 are provided on both sides of the support plate 41, sliding plates 43 are provided on both sides of the support plate 41, and one end of the sliding plate 43 facing the scraper group 3 is rotatably connected to the scraper group 3, and the ends of the two sliding plates 43 facing each other are fixedly mounted with sliding shafts 431, and the two sliding shafts 431 respectively pass through two symmetrically arranged guide bevel grooves 4101, and a telescopic member 21 for driving the sliding plate 43 to move up and down is provided on the mounting frame 2.

[0027] Among them, by setting a support plate 41 under the mounting frame 2 and setting a guide bevel groove 4101 on the support plate 41, when the sliding plate 43 moves up and down driven by the telescopic member 21, the guide bevel groove 4101 will guide the sliding plate 43 to move left and right, so that the two groups of scraper groups 3 are close to or away from each other. When the mounting frame 2 is placed into the interior of the pipeline 1, the sliding plate 43 can be moved downward to drive the two groups of scraper groups 3 to approach each other, so that they can enter the interior of the pipeline 1 more easily.

[0028] Furthermore, if Figure 4 and Figure 6 As shown, it also includes a linkage plate 42, which is slidably installed up and down under the mounting frame 2, the telescopic end of the telescopic member 21 is fixedly connected to the linkage plate 42, and connecting plates 421 are fixedly installed at both ends of the linkage plate 42, and the two connecting plates 421 are respectively slidably connected to the two sliding plates 43, and the upward movement of the connecting plate 421 is used to drive the sliding plate 43 to move upward, and at the same time, the sliding plate 43 moves away from the middle of the mounting frame 2; the downward movement of the connecting plate 421 is used to drive the sliding plate 43 to move downward, and at the same time, drive the sliding plate 43 to move toward the middle of the mounting frame 2.

[0029] Among them, by setting the linkage plate 42, the left and right movement of the sliding plate 43 in the horizontal direction can be more conveniently controlled, so that the rotation angle of the sliding plate 43 does not change during the up and down movement, and the two groups of scraper groups 3 can be driven closer or farther from each other more smoothly.

[0030] Furthermore, if Figure 5 and Figure 6 As shown, a rotating connecting shaft 432 is provided at one end of the sliding plate 43 away from the sliding shaft 431. The rotating connecting shaft 432 is used to be rotatably connected to the mutually rotating connection of the two inclined tool holders 32. The up and down movement of the rotating connecting shaft 432 drives the two inclined tool holders 32 to bend toward each other.

[0031] Among them, by arranging a rotating connecting shaft 432 on the sliding plate 43, the position where the two inclined tool holders 32 are connected to each other can be rotatably connected to the sliding plate 43, so that in the process of the sliding plate 43 moving up and down, it can not only drive the two groups of scraper groups 3 to approach each other (for the convenience of understanding, it is assumed to be in the X-axis direction), but also drive the middle parts of the two inclined tool holders 32 to extend downward or retract, so that the two groups of scraper groups 3 can be shortened in the length direction (in the Y-axis direction). By controlling the lifting position of the sliding plate 43, the overall size of the scraper group 3 can be conveniently controlled, which can not only adapt to pipes 1 of different sizes, but also before cleaning, the size of the scraper group 3 can be conveniently reduced to make the mounting frame 2 as a whole convenient to be placed inside the pipe 1.

[0032] It should be noted that, in the working state, the middle parts of the two inclined tool holders 32 are in a raised triangular shape, which can more smoothly scrape off the oil smoke on the inner wall of the pipe 1, making it easier to clean the oil smoke inside the pipe 1.

[0033] Furthermore, if Figure 5 As shown, sliding frames 25 are slidably installed on both sides below the mounting frame 2, and one side of each sliding frame 25 in the length direction is slidably connected to two groups of scraper groups 3 respectively. The sliding frame 25 is slidably connected to the mounting frame 2 in the width direction, and the sliding frame 25 is used to support the horizontal knife holder 31 to slide in the horizontal direction.

[0034] Among them, by arranging the sliding frame 25 on the mounting frame 2, not only can the scraper group 3 be stably supported, but also each scraper group 3 can be extended and retracted in the length direction (Y-axis direction), which can increase the adaptation range of the scraper group 3.

[0035] Furthermore, if Figure 5 and Figure 6 As shown, a storage box 23 is fixedly installed above the mounting frame 2, and the storage box 23 is used to store cleaning liquid. The horizontal tool holder 31 and the two inclined tool holders 32 are each provided with a spray pipe 322, and each of the spray pipes 322 sprays cleaning liquid to the bottom of each scraper 321 respectively. Conveying parts for conveying the cleaning liquid to the horizontal tool holder 31 and the inclined tool holder 32 are provided on both sides of the storage box 23.

[0036] Among them, by setting a storage box 23 above the mounting frame 2, the cleaning liquid can be stored, and at the same time, a spray pipe 322 is set on the horizontal tool holder 31 and the inclined tool holder 32. In the process of the mounting frame 2 moving downward, when too much oil smoke accumulates on the horizontal tool holder 31 and the inclined tool holder 32, the scraper 321 on the horizontal tool holder 31 and the inclined tool holder 32 can be conveniently cleaned through the conveying member, and the oil smoke on the inside of the pipeline 1 can be conveniently continued to be scraped off.

[0037] Furthermore, if Figure 6 and Fig. 9 As shown, the conveying member includes an extraction cylinder 22 fixedly mounted on the mounting frame 2, the two ends of the extraction cylinder 22 are closed, a piston 223 is arranged inside the extraction cylinder 22, a sliding rod 224 is fixedly installed below the piston 223, the lower end of the sliding rod 224 extends out of the extraction cylinder 22 and slides through the mounting frame 2, the lower end of the sliding rod 224 is fixedly connected to the linkage plate 42, and a conveying pipe 221 and a suction pipe 222 are respectively arranged below the extraction barrel 22, the conveying pipe 221 is used to connect the ejection pipe 322 with the extraction cylinder 22, the suction pipe 222 is used to connect the storage box 23 with the inside of the extraction cylinder 22, and the conveying pipe 221 and the suction pipe 222 are both provided with a one-way valve.

[0038] Among them, by fixing the extraction cylinder 22 on the mounting frame 2, when the linkage plate 42 moves up and down, the sliding rod 224 extending from the inside of the extraction cylinder 22 can be conveniently driven to move up and down, thereby controlling the piston 223 inside the position extraction cylinder 22 to move up and down. When the linkage plate 42 moves upward, the piston 223 can be driven to move upward, so that a negative pressure state is generated inside the extraction cylinder 22, and the cleaning liquid can be drawn from the inside of the storage box 23 along the suction pipe 222 into the inside of the extraction cylinder 22. Then, in the process of the linkage plate 42 moving downward, the piston 223 is driven to move downward, so that the cleaning liquid inside the extraction cylinder 22 is transported along the delivery pipe 221 to the ejection pipe 322 and sprayed toward the scraper 321.

[0039] Furthermore, if Figure 8 As shown, the ejection pipe 322 is laid along the bottom of the scraper 321 , and a ejection slot 323 is provided on the ejection pipe 322 facing the blade of the scraper 321 , and the ejection slot 323 is inclined upward toward the blade of the scraper 321 .

[0040] Among them, by arranging the ejection slot 323 on the ejection pipe 322, the cleaning liquid can have a greater impact force during the ejection process, and the oil smoke attached to the scraper 321 can be washed off more quickly, thereby improving the cleaning efficiency of the oil smoke inside the pipeline 1.

[0041] Furthermore, it also includes a fixing frame 231, which is fixedly installed on the mounting frame 2 by bolts, and the fixing frame 231 is used to fix the storage box 23; the storage box 23 can be conveniently fixed.

[0042] Working principle: when it is necessary to clean the scrapers 321 on the two scraper groups 3, the telescopic part 21 can be controlled to extend. On the one hand, the two scraper groups 3 can be controlled to retract so that the scraper 321 no longer fits the inner wall of the pipe 1. On the other hand, the linkage plate 42 is driven to move downward so that the cleaning liquid inside the extraction cylinder 22 is sprayed out from the spray pipe 322 under the pressurized environment of the piston 223, so that the scraper 321 can be cleaned quickly to prevent the accumulated oil smoke from blocking the downward pressure of the mounting frame 2.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
