Abstract
Description
Technical Field
[0001] This utility model relates to the field of yellow phosphorus production technology, and in particular to a flue gas anti-blocking and gas guiding structure in yellow phosphorus production. Background Technology
[0002] During the production process of yellow phosphorus electric furnace, high-temperature flue gas is discharged along with a large amount of phosphorus dust and condensate, which can easily form stubborn scale on the inner wall of the flue and the surface of the filter screen, resulting in a reduction in the flow cross section of the pipeline or even complete blockage.
[0003] Traditional air-guiding structures mostly use fixed filters, requiring shutdown and flange removal or pipe cutting for cleaning and maintenance. This is not only labor-intensive and time-consuming, but frequent disassembly and assembly can also damage the sealing structure, seriously affecting production continuity. Although some designs have attempted to open cleaning ports on the side walls of the pipes, they cannot achieve the coordinated operation of quick filter replacement and online scraping of scale, making them inconvenient to use.
[0004] Therefore, this application provides a flue gas anti-blocking and gas guiding structure for yellow phosphorus production to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A flue gas anti-clogging and gas guiding structure for yellow phosphorus production includes a top cover of a yellow phosphorus electric furnace. A flue gas guide pipe is installed on the top of the top cover. A cleaning box is fixed on the surface of the flue gas guide pipe and communicates with the interior of the flue gas guide pipe. A base plate is inserted and installed on the cleaning box. A filter screen core is detachably installed on the portion of the base plate that extends into the flue gas guide pipe. A drain port is opened on one side of the cleaning box, and a cleaning plate is elastically installed on the other side of the cleaning box. A cleaning brush is provided on the surface of the cleaning plate and elastically abuts against the side of the base plate away from the drain port.
[0007] Optionally, flanges are provided at both ends of the smoke guide pipe.
[0008] Optionally, the top of the substrate extends beyond the top of the cleaning box and is fixed with a handle, and the lower end of the substrate is provided with a mounting groove for the filter core to slide out.
[0009] Optionally, a plurality of horizontal guide posts are fixed on the side of the cleaning plate away from the cleaning brush. The guide posts horizontally penetrate the inner wall of the cleaning box, and springs are sleeved on the guide posts.
[0010] Optionally, at least two guide posts are provided.
[0011] Optionally, one end of the spring is fixed to the inner wall of the cleaning box, and the other end abuts against the cleaning plate, and the cleaning plate abuts against the square drain outlet.
[0012] Optionally, a limit bolt is threaded into the end of the guide post that extends out of the cleaning box.
[0013] Compared with the prior art, this utility model has at least the following beneficial effects:
[0014] In the above solution, thanks to the cooperation of the cleaning box, the base plate and the filter element, the base plate can be easily pulled out from the flue to replace and maintain the filter element, thus avoiding the problem of dirt accumulating on the filter element during long-term use and affecting the efficiency of subsequent flue gas ducting.
[0015] In the above solution, thanks to the flexible installation of the cleaning plate and the drain port on the side of the cleaning box, the cleaning plate can elastically scrape the dirt on the filter core during the process of the base plate being pulled out of the smoke pipe and the cleaning box, and discharge the cleaned dirt from the drain port. This allows the base plate and filter core to be quickly cleaned by repeatedly moving and inserting them in the cleaning box.
[0016] In summary, this device not only facilitates the replacement and maintenance of its cleaning components, but also allows for rapid cleaning and maintenance, which helps to ensure the proper drainage of flue gas from the yellow phosphorus electric furnace, resulting in excellent performance.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation
[0026] The following is a detailed description of a flue gas anti-clogging and gas guiding structure for yellow phosphorus production provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0027] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0028] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.
[0029] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.
[0030] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.
[0031] like Figure 1 As shown, an embodiment of this utility model provides a flue gas anti-blocking and gas guiding structure for yellow phosphorus production, including a flue gas guide pipe 2 installed on the top cover 1 of the yellow phosphorus electric furnace. The flue gas guide pipe 2 is made of high-temperature resistant alloy material, and its inner wall can be specially treated to make its surface smooth, so as to reduce the resistance of flue gas during the flow process.
[0032] To facilitate the assembly and disassembly of the flue pipe 2 and its connection to other equipment, flanges 201 are installed at both ends of the flue pipe 2. Each flange 201 has multiple evenly distributed bolt holes, allowing the flue pipe 2 to be easily and securely connected to adjacent pipes or equipment using bolts, ensuring smooth flow of flue gas. During the connection process, sealing gaskets are also installed between the flanges 201 to prevent flue gas leakage.
[0033] like Figure 2 , Figure 3 and Figure 4 As shown, a cleaning box 3 is fixed to the lower side surface of the smoke guide pipe 2. A base plate 4 is inserted and installed on the cleaning box 3. The top of the base plate 4 extends beyond the top of the cleaning box 3 and is fixed with a handle 401. The handle 401 is covered with a non-slip material for easy gripping by the operator. The base plate 4 can be easily operated through the handle 401 to insert and remove the base plate 4.
[0034] The portion of the substrate 4 extending into the smoke guide pipe 2 is detachably fitted with a filter element 5. Specifically, the lower end of the substrate 4 has a mounting groove 402 for the filter element 5 to slide out. The edge of the filter element 5 is provided with a slide rail that matches the mounting groove 402, allowing the filter element 5 to be inserted or removed along the mounting groove 402 (a certain degree of interference fit is preferred to ensure installation effectiveness). In this embodiment, the filter element 5 can be made of multiple layers of stainless steel wire mesh. This structure can effectively filter impurities and particulate matter in the flue gas while ensuring smooth passage of the flue gas. During long-term use, impurities and particulate matter from the flue gas will gradually accumulate on the filter element 5. When the accumulation reaches a certain level and affects the flue gas guiding efficiency, simply pull the substrate 4 out of the cleaning box 3 and the smoke guide pipe 2 using the handle 401, and then slide the filter element 5 out of the mounting groove 402 for replacement or cleaning. This avoids the cumbersome operation of disassembling the entire smoke guide device, which requires stopping the machine in traditional structures, greatly improving production efficiency.
[0035] Cooperate Figure 5 As shown, a drain port 301 is provided on one side of the cleaning box 3, and a guide plate is provided on the edge of the drain port 301 for discharging dirt generated during the cleaning process. A cleaning plate 6 is elastically installed on the other side of the cleaning box 3. A cleaning brush 601 is provided on the surface of the cleaning plate 6. The cleaning brush 601 is made of high-strength wear-resistant material and can effectively scrape the surface of the filter element 5. The cleaning plate 6 elastically abuts against the side of the base plate 4 away from the drain port 301.
[0036] In this embodiment, multiple horizontal guide posts 602 are fixed to the side of the cleaning plate 6 away from the cleaning brush 601. The guide posts 602 are made of high-strength steel and horizontally penetrate the inner wall of the cleaning box 3. Springs 603 are fitted onto the guide posts 602, and two sets of guide posts 602 and springs 603 are provided to ensure that the cleaning plate 6 can stably and elastically abut against the base plate 4. One end of the spring 603 is fixed to the inner wall of the cleaning box 3, and the other end abuts against the cleaning plate 6, pushing the cleaning plate 6 towards the drain outlet 301. A limit bolt 604 is threaded into the end of the guide post 602 that protrudes from the cleaning box 3. The limit bolt 604 prevents the guide post 602 from sliding out of the cleaning box 3, ensuring the stability of the cleaning plate 6 installation. When installing the limit bolt 604, its position is adjusted according to the actual situation to control the elastic abutment force of the cleaning plate 6.
[0037] When the filter element 5 needs cleaning, the base plate 4 is moved back and forth by the handle 401. During the movement of the base plate 4, the cleaning plate 6, under the elastic force of the spring 603, remains firmly against the base plate 4. The cleaning brush 601 scrapes the surface of the filter element 5, removing dirt from it. The scraped-off dirt moves gradually towards the drain port 301 within the cleaning box 3 as the base plate 4 is moved, facilitating discharge from the drain port 301. In this way, the base plate 4 and the filter element 5 can be quickly cleaned by repeatedly moving and inserting them into the cleaning box 3, without the need for additional cleaning equipment or complicated operating procedures, greatly improving cleaning efficiency.
[0038] The working principle provided by this utility model is that the flue gas anti-clogging and gas guiding structure in the production of yellow phosphorus, through the cooperation of the cleaning box 3, the base plate 4 and the filter core 5, makes it easy to pull the base plate 4 out of the flue gas guiding pipe 2, thereby replacing and maintaining the filter core 5, avoiding the problem of dirt accumulating on the filter core 5 during long-term use and affecting the subsequent flue gas guiding efficiency.
[0039] Meanwhile, thanks to the flexible installation of the cleaning plate 6 and the drain port 301 on the side of the cleaning box 3, the cleaning plate 6 can elastically scrape the dirt on the filter element 5 during the process of the base plate 4 being pulled out of the smoke pipe 2 and the cleaning box 3, and discharge the cleaned dirt from the drain port 301. This allows the base plate 4 and the filter element 5 to be quickly cleaned by repeatedly moving and inserting them in the cleaning box 3.
[0040] In summary, this device not only facilitates the replacement and maintenance of its cleaning components, but also allows for rapid cleaning and maintenance, ensuring proper drainage of the flue gas from the yellow phosphorus electric furnace and demonstrating excellent performance.
[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
