Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge thermal desorption reactor. Background Technology

[0002] Oily sludge is one of the main pollutants generated during the extraction, transportation, and processing of petroleum. Its composition is relatively complex and it has a certain degree of toxicity. If it is discharged directly without treatment, it will not only waste petroleum resources but also pollute the surrounding natural environment. Thermal treatment technology, mainly consisting of pyrolysis and incineration, can effectively treat oily sludge and realize its resource utilization and harmlessness. However, the incineration process produces a large amount of harmful gases, causing secondary pollution. Moreover, existing thermal desorption treatment devices for oily sludge are inconvenient to maintain during use and have poor treatment efficiency.

[0003] The existing patent publication number CN216572559U describes a thermal desorption treatment device for oily sludge. By rotating the threaded cap, the threaded cap is disengaged from the threaded post. Through the movable filter frame, the filter frame is disengaged from the annular groove, which facilitates the disassembly of the filter frame, cleaning or replacement of the filter screen and adsorption layer, and maintenance of the device.

[0004] Although the aforementioned patent allows for the disassembly of the filter frame to clean or replace the filter screen, the filter frame is bolted, requiring frequent tightening and loosening of the bolts for disassembly and assembly. This makes the disassembly and assembly process cumbersome, hindering the quick disassembly and assembly of the filter frame and the filter screen, thus affecting the speed of filter screen disassembly and maintenance. Therefore, there is a need for a sludge thermal desorption reactor that can quickly disassemble and assemble the filter screen. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a sludge thermal desorption reactor that can solve the problem that the filter frame is connected by bolts, which requires frequent tightening and loosening of bolts to disassemble and assemble the filter frame, resulting in a cumbersome disassembly and assembly process. This makes it inconvenient to quickly disassemble and assemble the filter frame and the filter screen, thus affecting the speed of disassembly and maintenance of the filter screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge thermal desorption reactor, comprising a reactor, wherein a feed inlet and a steam exhaust pipe are provided at the top of the reactor, and two sliding grooves are provided on the inner wall of the steam exhaust pipe, and fixed blocks are slidably connected inside the two sliding grooves, and a filter frame is provided between the two fixed blocks, and a filter screen is fixedly installed inside the filter frame, and grooves are provided at the opposite ends of the two fixed blocks, and quick-release components are provided inside the two grooves, each quick-release component including two sliding blocks, the outer surfaces of the two sliding blocks being slidably connected to the inner walls of the corresponding grooves, the opposite ends of the two sliding blocks extending into corresponding grooves, the opposite ends of the two sliding blocks being beveled ends, and pressure springs being fixedly installed at the opposite ends of the two sliding blocks, the opposite ends of the two pressure springs being fixedly connected to the inner walls of the grooves.

[0007] Furthermore, each of the two fixing blocks has a connecting groove at its top, and the interior of each connecting groove is connected to the interior of the corresponding groove. A push plate is slidably installed on the inner wall of each connecting groove.

[0008] Furthermore, the top ends of the two push plates extend into the interior of two connecting grooves, and the bottom ends of the two push plates are fixedly connected to the top ends of the corresponding sliding blocks.

[0009] Furthermore, fixing grooves are provided on both sides of the inner walls of the two sliding grooves, and the interiors of the two fixing grooves are slidably connected to the inclined ends of the two sliding blocks respectively.

[0010] Furthermore, each of the two fixed blocks has a mounting groove at its opposite ends, and a mounting plate is slidably connected inside each of the two mounting grooves. The opposite ends of the two mounting plates are fixedly connected to the two sides of the filter frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This sludge thermal desorption reactor, through the setting of quick-release components, allows for convenient disassembly and assembly of the filter frame and filter screen inside the steam exhaust pipe, making operation more convenient. At the same time, the filter screen can also be flexibly disassembled and assembled inside the filter frame, making it easier for the filter frame and filter screen to work together. This solves the shortcomings of traditional filter frames and filter screens that are inconvenient to disassemble and assemble quickly, thereby improving the practicality of the reactor.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Please see Figure 1-5This utility model provides a technical solution: a sludge thermal desorption reactor, including a reactor 1. The top of the reactor 1 is provided with a feed inlet 2 and a steam exhaust pipe 3. The inner wall of the steam exhaust pipe 3 is provided with two sliding grooves 4. The interior of each of the two sliding grooves 4 is slidably connected with a fixing block 7. A filter frame 5 is provided between the two fixing blocks 7. A filter screen 6 is fixedly installed inside the filter frame 5. The opposite ends of the two fixing blocks 7 are provided with grooves 10. The interior of each of the two grooves 10 is provided with a quick-release assembly. The two quick-release assemblies include two sliding blocks 11. The outer surfaces of the two sliding blocks 11 are slidably connected to the inner walls of the corresponding grooves 10. The opposite ends of the two sliding blocks 11 are respectively connected to the corresponding grooves 10. The opposite ends of the two sliding blocks 11 are both inclined ends. The opposite ends of the two sliding blocks 11 are fixedly installed with pressure springs 14. The opposite ends of the two pressure springs 14 are fixedly connected to the inner walls of the grooves 10.

[0019] Furthermore, each of the two fixed blocks 7 has a connecting groove 12 at its top, and the interior of the two connecting grooves 12 is connected to the interior of the corresponding grooves 10. Push plates 13 are slidably installed on the inner walls of the two connecting grooves 12.

[0020] Furthermore, the top ends of the two push plates 13 extend into the interior of the two connecting grooves 12, and the bottom ends of the two push plates 13 are fixedly connected to the top ends of the corresponding sliding blocks 11.

[0021] Furthermore, two fixing grooves 15 are provided on both sides of the inner wall of the two sliding grooves 4, and the interior of the two fixing grooves 15 is slidably connected to the inclined ends of the two sliding blocks 11 respectively.

[0022] Furthermore, each of the two fixed blocks 7 has an installation groove 8 at its opposite ends, and an installation plate 9 is slidably connected inside each of the two installation grooves 8. The opposite ends of the two installation plates 9 are fixedly connected to the two sides of the filter frame 5.

[0023] Furthermore, during the sludge thermal desorption reaction, the sludge to be treated enters the furnace body through the feed inlet 2 at the top of the reactor 1. After heating and other treatments, the volatile substances in the sludge are converted into steam and discharged through the steam exhaust pipe 3. This avoids the solid impurities carried in the steam from contaminating subsequent equipment or affecting the emission quality. When the steam flows through the steam exhaust pipe 3, it must first pass through the filter screen 6 inside the filter frame 5. The filter screen 6 will intercept and filter the impurities in the steam to ensure that the cleanliness of the discharged steam meets the requirements. Here, the reactor 1, feed inlet 2, and steam exhaust pipe 3 can be referred to in the existing announcement CN216572559U, "A Thermal Desorption Treatment Device for Oily Sludge," which describes the mixing tank, feeding port, and steam exhaust pipe. Since the reactor 1 and its internal structure are existing equipment, they will not be described in detail here.

[0024] Furthermore, the installation process of the filter assembly embodies a convenient design: When installing the filter frame 5, first align the mounting plates 9 on both sides of the filter frame 5 with the mounting grooves 8 on the fixing block 7, push the filter frame 5 so that the mounting plates 9 slide into the mounting grooves 8, completing the initial assembly of the filter frame 5 and the fixing block 7. Then, push the assembled assembly downwards along the sliding groove 4 on the inner wall of the steam exhaust pipe 3. At this time, the inclined ends of the sliding blocks 11 in the grooves 10 on both sides of the fixing block 7 will contact and be squeezed with the inner wall of the sliding groove 4, causing the sliding blocks 11 to retract into the groove 10, while compressing the pressure spring 14. When the fixing block 7 is pushed to the designated position, the sliding blocks 11 will align with the fixing groove 15 on the inner wall of the sliding groove 4. The pressure spring 14 will restore its deformation and push the sliding blocks 11, causing the inclined ends of the sliding blocks 11 to slide into the fixing groove 15, thereby enabling the two fixing blocks 7 to drive the filter frame 5 to be fixedly installed inside the steam exhaust pipe 3. The operation process is simple and quick.

[0025] Furthermore, when the filter screen 6 needs to be cleaned or replaced, it can be quickly disassembled by pushing the push plate 13. By pushing the two push plates 13 in opposite directions, the push plates 13 slide along the connecting groove 12 and drive the sliding block 11, so that the sliding block 11 overcomes the elastic force of the pressure spring 14 and retracts into the groove 10, disengaging from the locking groove 15. At this time, the fixing block 7 is pulled out upward along the sliding groove 4, and the filter frame 5 together with the fixing block 7 can be taken out from the steam exhaust pipe 3. Then, the mounting plate 9 of the filter frame 5 is slid out from the mounting groove 8 of the fixing block 7, and the filter screen 6 can be maintained or replaced separately.

[0026] Furthermore, the quick-release assembly allows for easy assembly and disassembly of the filter frame 5 and filter screen 6 within the steam exhaust pipe 3, making the operation more convenient. Simultaneously, the filter screen 6 can also be flexibly assembled and disassembled within the filter frame 5, making it easier for the filter frame 5 and filter screen 6 to work together. This solves the problem of the traditional filter frame 5 and filter screen 6 being difficult to assemble and disassemble quickly, thereby improving the practicality of the reactor.

[0027] Structural Description: Reactor 1: It is the core equipment for sludge thermal desorption treatment, providing space for sludge heating treatment. After the sludge to be treated is heated inside, the volatile substances are converted into steam. The overall structure can refer to the stirred tank structure of existing similar devices. Feed inlet 2: Located at the top of reactor 1, it is the channel for the sludge to be treated to enter the interior of reactor 1. It can be referenced from the feed inlet of existing devices to facilitate the input of sludge for treatment.

It can refer to the same type of pipe in the existing equipment to provide a path for steam transportation. Slide 4: It is formed on the inner wall of the steam exhaust pipe 3 to allow the fixed block 7 to slide, providing guidance and support for the installation of components such as the fixed block 7 and the filter frame 5, and facilitating the positioning and installation of the components. Filter frame 5: Installed between two fixed blocks 7, with a filter screen 6 fixed inside, serving to support the filter screen 6 and, in conjunction with the filter screen 6, to intercept and filter impurities in the steam. Filter screen 6: Fixed inside the filter frame 5, it filters solid impurities carried in the steam as it flows through, ensuring the cleanliness of the discharged steam and preventing contamination of downstream equipment. Fixed block 7: It is slidably connected in the slide groove 4 and is used to install and fix the filter frame 5. Its structural design, together with the quick-release component, enables convenient installation and removal of the filter frame 5. Mounting slot 8: Located at the opposite end of the fixing block 7, it is used for sliding insertion of the mounting plate 9. The connection between the filter frame 5 and the fixing block 7 is achieved through the cooperation of the mounting plate 9 and the mounting slot 8. Mounting plate 9: Fixed on both sides of filter frame 5, it is slidably connected to mounting groove 8. It is a key component for connecting filter frame 5 and fixing block 7, so that filter frame 5 can be stably installed on fixing block 7. Groove 10: It is formed on the opposite end of the fixing block 7 to provide installation space for the sliding block 11 and the pressure spring 14, so that the components of the quick-release assembly can be arranged reasonably and function properly. Sliding block 11: It is slidably connected in the groove 10, with the opposite end being a beveled end. It is compressed and contracted during installation, and pops out and snaps into the fixing groove 15 after it is in place, thereby fixing the fixing block 7. It can be pushed and contracted during disassembly.

[0028] Connecting groove 12: It is opened at the top of the fixed block 7 and communicates with the groove 10. It provides a channel for the sliding of the push plate 13, so that the push plate 13 can drive the sliding block 11 to move. Push plate 13: It is slidably installed in the connecting groove 12, with its top end extending out of the connecting groove 12 and its bottom end fixed to the sliding block 11. Pushing the push plate 13 can drive the sliding block 11 to move, making it easy to disassemble the fixing block 7.

[0029] Pressure spring 14: One end is fixed to the sliding block 11, and the other end is fixed to the inner wall of the groove 10, providing elastic force to the sliding block 11 so that the sliding block 11 can pop out and lock into the fixing groove 15 or reset after being pressed.

[0030] Fixed groove 15: It is formed on both sides of the inner wall of the slide groove 4 and is slidably connected to the inclined end of the sliding block 11. When the sliding block 11 is engaged, it can fix the fixed block 7 in the slide groove 4 to prevent it from moving.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
