Description
Technical Field
[0001] The utility model relates to the technical field of waste gas pipelines, in particular to an anti-blocking structure at a throat portion of a waste gas pipeline elbow. Background Art
[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health.
[0003] When exhaust gas is discharged, a pipe is needed. The throat of the pipe is prone to blockage, which requires anti-blocking treatment.
[0004] The anti-clogging structure currently used is generally a fixed structure, and the degree of curvature at the bends of different exhaust pipes is different. The existing anti-clogging structure cannot be adjusted. Different bend groups need to be equipped with specific anti-clogging structures, which increases the cost of use. Utility Model Content
[0005] The utility model aims to provide an anti-blocking structure at the throat of an exhaust pipe elbow to solve the problems raised in the above-mentioned background technology.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0007] A structure for preventing blockage at the throat of a waste gas pipe bend comprises a fixed pipe and a fixing part, wherein the fixed pipe is fixedly installed on one end of the bend through the fixing part, the bottom of the bend is fixedly connected to a connecting pipe through a connecting part, a filter plate is clamped inside the bend, a fixing plate is fixedly installed on the bottom of the fixed pipe, a first through groove is provided at the bottom of the fixed pipe, the first through groove corresponds to the top of the fixed plate, an adjusting component is provided inside the fixed plate, the adjusting component is used to block or open the inside of the fixed plate, a rotating plate is fixedly installed on one end of the connecting pipe, a second through groove is provided at one end of the connecting pipe, the second through groove corresponds to the other end of the rotating plate, the rotating plate is located on one side of the fixed plate, a controller is fixedly installed on one side of the rotating plate, the fixed plate and the rotating plate are rotatably connected by a rotating shaft, a through hole is provided inside the rotating shaft.
[0008] By installing the filter plate, the exhaust gas entering the inner part of the elbow can be filtered and the impurities contained in the exhaust gas can be intercepted, so as to facilitate the subsequent other treatment of the exhaust gas. When the filter plate can be used normally, the adjusting component can cover the inside of the fixed plate so that the exhaust gas can flow inside the fixed pipe, the elbow and the connecting pipe. After the exhaust gas speed flowing on the surface of the filter plate drops to a certain standard, the opening of the fixed plate can be opened by using the adjusting component so that the exhaust gas can directly flow from the inside of the fixed pipe into the inside of the fixed plate, and then be discharged through the inside of the rotating plate and the connecting pipe, so that the user can clean or replace the filter plate in time. After the filter plate is cleaned or replaced, the adjusting component can cover the inside of the fixed plate again so that the exhaust gas can pass through the inside of the elbow again, thereby achieving an anti-blocking effect. According to the different bending degrees of the elbow, the rotating plate can be driven to rotate with the fixed plate by installing the rotating shaft, so as to connect and fix the fixed plate and the rotating plate with the fixed pipe and the connecting pipe, thereby expanding the scope of application of the device.
[0009] A further improvement of the technical solution of the utility model is that the adjusting component includes a connecting plate, which is fixedly connected to the inner wall of the fixed plate, and a baffle is slidably installed inside the fixed plate through an electric push rod, and the baffle is in contact with the bottom of the connecting plate.
[0010] The above-mentioned technical solution is adopted. In this solution, by installing an electric push rod, the baffle plate can be driven to move upward, so that the baffle plate and the connecting plate are fitted together, thereby shielding the interior of the fixed plate and preventing exhaust gas from passing through the interior of the fixed plate. When the electric push rod drives the baffle plate to move downward, the baffle plate and the connecting plate can be separated, thereby opening the opening inside the fixed plate to facilitate the circulation of exhaust gas inside the fixed plate.
[0011] A further improvement of the technical solution of the utility model is that a sealing strip is attached to the bottom of the connecting plate, and the sealing strip is embedded in the inner part of the baffle.
[0012] By adopting the above technical solution, in this solution, the contact area between the baffle and the connecting plate can be expanded by installing a sealing strip, thereby improving the sealing effect of the connection position between the baffle and the connecting plate, and further preventing the exhaust gas from passing through the interior of the fixed plate.
[0013] A further improvement of the technical solution of the utility model is that a protective cover is fixedly installed on the bottom of the baffle, and the protective cover is located on the periphery of the electric push rod.
[0014] The above technical solution is adopted. In this solution, the periphery of the electric push rod can be shielded by installing a protective cover to prevent exhaust gas from invading the surface and interior of the electric push rod and affecting the electric push rod, thereby protecting the electric push rod.
[0015] A further improvement of the technical solution of the utility model is that a partition is slidably installed on the other side of the bent pipe, the partition is mutually engaged with the periphery of the filter plate, and springs are fixedly installed at both ends of the bent pipe, and the springs are fixedly connected to both ends of the partition.
[0016] The above-mentioned technical solution is adopted. In this solution, when the user removes the filter plate from one side, the partition can be automatically squeezed to one side by the elastic force of the spring itself, so that the partition and the filter plate fit tightly together, so that the partition can be used to temporarily close the inside of the bent pipe to facilitate cleaning or replacement of the filter plate. When the filter plate is cleaned or replaced, the filter plate can be pushed into the inside of the bent pipe again from one side, and the partition can be squeezed to the other side at the same time, so as to facilitate the installation and use of the filter plate.
[0017] A further improvement of the technical solution of the utility model is that: limit blocks are fixedly installed at both ends of the filter plate, and the limit blocks are slidably connected with the inside of the bent pipe.
[0018] By adopting the above technical solution, in this solution, the sliding track of the filter plate inside the elbow can be guided and limited by installing the limit block, thereby facilitating the installation and removal of the filter plate.
[0019] A further improvement of the technical solution of the utility model is that a pull block is fixedly installed on one side of the filter plate.
[0020] By adopting the above technical solution, in this solution, the contact area between the user's hand and the filter plate can be enlarged by installing the pull block, so as to facilitate taking the filter plate out from the inside of the bent pipe from one side.
[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0022] 1. The utility model provides an anti-clogging structure at the throat of the elbow of the exhaust pipe. When the exhaust gas velocity flowing on the surface of the filter plate drops to a certain standard, the exhaust gas can be directly flowed from the inside of the fixed pipe into the inside of the fixed plate by using an adjusting component, and then discharged through the inside of the rotating plate and the connecting pipe, ensuring that the exhaust gas can circulate normally, so as to facilitate the cleaning or replacement of the filter plate. When the device is installed and assembled, the rotating plate can be rotated by using a rotating shaft, so as to facilitate the installation of the fixed plate and the rotating plate between the elbows with different bending degrees, thereby expanding the scope of application of the device.
[0023] 2. The utility model provides an anti-blocking structure at the throat of the exhaust pipe elbow. Through the cooperation between the spring and the partition, the partition can be used to temporarily close the inside of the elbow during the removal of the filter plate to facilitate cleaning or replacement of the filter plate.

[0035] In this embodiment, by installing the filter plate 7, the exhaust gas entering the inner part of the elbow 1 can be filtered and the impurities contained in the exhaust gas can be intercepted, so as to facilitate the subsequent other treatment of the exhaust gas. When the filter plate 7 can be used normally, the adjusting component 9 can block the inside of the fixed plate 5, so that the exhaust gas can flow inside the fixed pipe 2, the elbow 1 and the connecting pipe 3. After the exhaust gas speed flowing on the surface of the filter plate 7 drops to a certain standard, the adjusting component 9 can be used to open the opening of the fixed plate 5, so that the exhaust gas can directly flow from the inside of the fixed pipe 2 into the inside of the fixed plate 5. The exhaust gas is then discharged through the rotating plate 6 and the interior of the connecting pipe 3, so that the user can clean or replace the filter plate 7 in time. After the filter plate 7 is cleaned or replaced, the adjusting component 9 can block the interior of the fixed plate 5 again, so that the exhaust gas can pass through the interior of the bent pipe 1 again, thereby achieving an anti-blocking effect. According to the different bending degrees of the bent pipe 1, the rotating shaft 8 can be installed to drive the rotating plate 6 to rotate with the fixed plate 5, so as to connect and fix the fixed plate 5 and the rotating plate 6 to the fixed pipe 2 and the connecting pipe 3, thereby expanding the scope of application of the device.
[0036] Example 2
[0037] like Figure 2 , Figure 5 and Figure 6As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the adjusting component 9 includes a connecting plate 902, which is fixedly connected to the inner wall of the fixed plate 5, and a baffle 901 is slidably installed inside the fixed plate 5 through an electric push rod 903, and the baffle 901 is fitted with the bottom of the connecting plate 902, and a sealing strip 904 is attached to the bottom of the connecting plate 902, and the sealing strip 904 is embedded with the inside of the baffle 901, and a protective cover 905 is fixedly installed on the bottom of the baffle 901, and the protective cover 905 is located on the periphery of the electric push rod 903.
[0038] In this embodiment, by installing the electric push rod 903, the baffle 901 can be driven to move upward, so that the baffle 901 and the connecting plate 902 are in contact with each other, thereby shielding the interior of the fixed plate 5 to prevent exhaust gas from passing through the interior of the fixed plate 5. When the electric push rod 903 drives the baffle 901 to move downward, the baffle 901 and the connecting plate 902 can be separated, thereby opening the opening inside the fixed plate 5 to facilitate the exhaust gas to circulate inside the fixed plate 5. By installing the sealing strip 904, the contact area between the baffle 901 and the connecting plate 902 can be expanded, thereby improving the sealing effect of the connection position between the baffle 901 and the connecting plate 902, and further preventing exhaust gas from passing through the interior of the fixed plate 5. By installing the protective cover 905, the periphery of the electric push rod 903 can be shielded to prevent exhaust gas from invading the surface and interior of the electric push rod 903 and affecting the electric push rod 903, thereby protecting the electric push rod 903.
[0039] Example 3
[0040] like Figure 2 , Figure 3 and Figure 4 As shown, based on Example 2, the utility model provides a technical solution: preferably, a partition 10 is slidably installed on the other side of the bent pipe 1, and the partition 10 is mutually engaged with the periphery of the filter plate 7, and springs 1001 are fixedly installed at both ends of the bent pipe 1, and the springs 1001 are fixedly connected to the two ends of the partition 10.
[0041] In this embodiment, when the user removes the filter plate 7 from one side, the partition plate 10 can be automatically squeezed to one side by the elastic force of the spring 1001 itself, so that the partition plate 10 and the filter plate 7 fit tightly together, so that the partition plate 10 can be used to temporarily close the inside of the bent pipe 1 to facilitate cleaning or replacement of the filter plate 7. When the filter plate 7 is cleaned or replaced, the filter plate 7 can be pushed into the inside of the bent pipe 1 from one side again, and the partition plate 10 can be squeezed to the other side at the same time, so as to facilitate the installation and use of the filter plate 7.
[0042] Example 4

When the exhaust gas velocity flowing on the surface of the filter plate 7 drops to a certain standard, the electric push rod 903 can be used to drive the baffle 901 to separate from the connecting plate 902, so that the exhaust gas can directly flow from the interior of the fixed pipe 2 into the interior of the fixed plate 5, and then be discharged through the rotating plate 6 and the interior of the connecting pipe 3. At this time, the user can The filter plate 7 is taken out from the side, and the filter plate 7 is cleaned or replaced. At the same time, the partition plate 10 is pushed to one side by the spring 1001 to cover the inside of the curved pipe 1. When the filter plate 7 is cleaned or replaced, the inside of the fixed plate 5 can be covered again, so that the exhaust gas passes through the inside of the curved pipe 1 again, thereby achieving an anti-clogging effect. According to the different bending degrees of the curved pipe 1, the user can use the rotating shaft 8 to drive the rotating plate 6 to rotate. After the adjustment is completed, the fixed plate 5 and the rotating plate 6 are connected to the fixed pipe 2 and the connecting pipe 3, thereby expanding the application range of the device.
