Description
Technical Field
[0001] This utility model relates to the field of dryer technology, specifically to a dryer that utilizes waste gas regeneration. Background Technology
[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It's used for drying objects by heating them to vaporize and release the moisture (generally water or other volatile liquid components) to obtain solid materials with a specified moisture content. A heatless dryer is a device that removes moisture from compressed air through physical adsorption, without requiring heating to regenerate the adsorbent. Its working principle involves using an adsorbent (such as molecular sieves or activated alumina) to adsorb moisture under high pressure and desorb and discharge the moisture under low pressure. In waste gas treatment, dryers are typically used to remove moisture. Removing moisture from the waste gas makes it easier for the dried gas to react with the treatment agent, thus improving the treatment effect. Simultaneously, drying reduces pollutant emissions, contributing to the protection of the atmospheric environment.
[0003] In the prior art, when drying waste gas using a dryer, the use of an adsorbent can adsorb the moisture in the waste gas, thereby achieving drying. However, after long-term use, the adsorption performance of the adsorbent decreases. Since it is not convenient to quickly replace the adsorbent, the reduced adsorption performance of the adsorbent will affect the quality and effect of drying the waste gas. Therefore, in order to solve the above problems, a waste gas regeneration dryer is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a waste gas regeneration dryer to solve the problem mentioned in the background art where the adsorption performance of the adsorbent decreases after long-term use, and the inconvenience of quickly replacing the adsorbent affects the quality and effect of waste gas drying.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas regeneration dryer, including a heatless dryer, an air inlet at the bottom of the heatless dryer, an adsorbent box movably connected to the inner side of the heatless dryer, a filter installed on one side of the heatless dryer via a pipe, a filter plate installed on the inner side of the filter, an air process tank installed on the side of the filter away from the heatless dryer via a pipe, and a nitrogen generator installed on the side of the air process tank away from the filter via a pipe, the nitrogen generator being connected to the heatless dryer via a pipe;
[0006] The inner side of the heatless dryer is provided with a replacement mechanism, which includes a connecting block. The connecting block is fixedly connected to the surface of the adsorbent box. A first fixing block is fixedly connected to the surface of the heatless dryer. An installation groove is opened on the inner side of the first fixing block. A movable groove is opened on the inner side of the first fixing block. A pull rod is movably connected to the inner side of the movable groove. An insert is fixedly connected to the bottom end of the pull rod. A slot is opened on the inner side of the connecting block.
[0007] Preferably, the replacement mechanism further includes a spring, which is fixedly connected to the surface of the insert block, and a sealing gasket is fixedly connected to the surface of the adsorbent box.
[0008] Preferably, the connecting blocks are in four groups and fixedly connected to the adsorbent box, the first fixing blocks are in four groups and fixedly connected to the heatless dryer, the connecting blocks are movably connected to the mounting groove, and the pull rod is movably connected to the first fixing block.
[0009] Preferably, the insert block is movable inside the movable groove, one end of the spring is fixedly connected to the movable groove, and the other end of the spring is fixedly connected to the insert block.
[0010] Preferably, the filter has an anti-clogging mechanism on its inner side. The anti-clogging mechanism includes a second fixing block, which is fixedly connected to the inner wall of the filter. A first rotating rod is movably connected to the inner side of the second fixing block. A first conical tooth is fixedly connected to the surface of the first rotating rod. A motor is fixedly installed on the surface of the filter. A second rotating rod is movably connected to the inner side of the second fixing block. A second conical tooth is fixedly connected to the top end of the second rotating rod. A brush plate is fixedly connected to the bottom end of the second rotating rod.
[0011] Preferably, the first rotating rod is movably connected to the heatless dryer, the end of the first rotating rod away from the first conical tooth is fixedly connected to the output end of the motor, and both the first and second conical teeth are movable inside the second fixed block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By moving the pull rod within the movable slot, combined with the elasticity of the spring, the insert block can move accordingly and engage and disengage with the slot. This allows for the limiting and releasing of the connecting block, facilitating the removal of the adsorbent box from the heatless dryer for rapid replacement of the adsorbent. This helps ensure the adsorption performance of the adsorbent, thereby guaranteeing the drying effect and quality of the waste gas.
[0014] The motor drives the first rotating rod to rotate, which in turn rotates the first conical tooth and drives the second conical tooth. This, in turn, causes the second rotating rod to rotate the brush plate. The rotation of the brush plate and its friction with the filter plate cleans the filter plate, preventing dust and other particles in the exhaust gas from accumulating on the filter plate and causing blockage. This ensures the entry and flow of exhaust gas and guarantees the filtration effect of the filter plate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-6 One embodiment provided by this utility model:
[0024] The motor 33 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described in detail here.
[0025] A waste gas regeneration dryer includes a heatless dryer 1, with an air inlet 11 at its bottom. An adsorbent box 12 is movably connected to the inside of the heatless dryer 1. A filter 13 is installed on one side of the heatless dryer 1 via a pipe, and a filter plate 14 is installed inside the filter 13. An air process tank 15 is installed on the side of the filter 13 away from the heatless dryer 1 via a pipe. A nitrogen generator 16 is installed on the side of the air process tank 15 away from the filter 13 via a pipe. The nitrogen generator 16 is connected to the heatless dryer via a pipe. The machine is connected to the air inlet 11, which allows exhaust gas to enter the heatless dryer 1. The adsorbent box 12 can adsorb the moisture in the exhaust gas. After the exhaust gas is treated by the filter 13 and the air process tank 15, it can be regenerated by the nitrogen generator 16. The exhaust gas discharged by the nitrogen generator 16 can regenerate the heatless dryer 1. The adsorbent can be regenerated without consuming additional compressed air, thereby reducing costs and extending the service life of the adsorbent in the adsorbent box 12.
[0026] The inner side of the heatless dryer 1 is provided with a replacement mechanism, which includes a connecting block 2. The connecting block 2 is fixedly connected to the surface of the adsorbent box 12. A first fixing block 21 is fixedly connected to the surface of the heatless dryer 1. An installation groove 22 is opened on the inner side of the first fixing block 21. A movable groove 23 is opened on the inner side of the first fixing block 21. A pull rod 24 is movably connected to the inner side of the movable groove 23. An insert block 25 is fixedly connected to the bottom end of the pull rod 24. A slot 26 is opened on the inner side of the connecting block 2. By moving the pull rod 24 in the movable groove 23, the pull rod 24 and the insert block 25 can be inserted and separated, which facilitates the limiting or releasing of the connecting block 2, thereby facilitating the removal of the adsorbent box 12 to replace the adsorbent and ensuring the drying of the exhaust gas.
[0027] Furthermore, the replacement mechanism also includes a spring 27, which is fixedly connected to the surface of the insert block 25. A sealing gasket 28 is fixedly connected to the surface of the adsorbent box 12. The sealing gasket 28 enables a sealed connection between the adsorbent box 12 and the heatless dryer 1 after the adsorbent box 12 is fixed.
[0028] Furthermore, the connecting blocks 2 are fixedly connected to the adsorbent box 12 in four groups, the first fixing blocks 21 are fixedly connected to the heatless dryer 1 in four groups, the connecting blocks 2 are movably connected to the mounting groove 22, and the pull rod 24 is movably connected to the first fixing block 21. The opening of the mounting groove 22 makes it easy to slide the connecting blocks 2 into the inside of the mounting groove 22 when the adsorbent box 12 is installed and used.
[0029] Furthermore, the insert 25 is movable inside the movable slot 23. One end of the spring 27 is fixedly connected to the movable slot 23, and the other end of the spring 27 is fixedly connected to the insert 25. By setting the spring 27, the insert 25 can be reset, thereby enabling the insert 25 and the slot 26 to be inserted into each other, which facilitates the limiting of the connecting block 2 and thus fixes the adsorbent box 12.
[0030] Furthermore, an anti-clogging mechanism is provided on the inner side of the filter 13. The anti-clogging mechanism includes a second fixing block 3, which is fixedly connected to the inner wall of the filter 13. A first rotating rod 31 is movably connected to the inner side of the second fixing block 3. A first conical tooth 32 is fixedly connected to the surface of the first rotating rod 31. A motor 33 is fixedly installed on the surface of the filter 13. A second rotating rod 34 is movably connected to the inner side of the second fixing block 3. A second conical tooth 35 is fixedly connected to the top of the second rotating rod 34. A brush plate 36 is fixedly connected to the bottom of the second rotating rod 34. By rotating the second rotating rod 34, the brush plate 36 can be rotated, thereby enabling the brush plate 36 to rotate and clean the surface of the filter plate 14. This can prevent the filter plate 14 from becoming clogged, thus affecting the entry and flow of exhaust gas and ensuring the filtration effect.
[0031] Furthermore, the first rotating rod 31 is movably connected to the heatless dryer 1. The end of the first rotating rod 31 away from the first conical tooth 32 is fixedly connected to the output end of the motor 33. The first conical tooth 32 and the second conical tooth 35 are both movable inside the second fixed block 3. Through the cooperation of the first conical tooth 32 and the second conical tooth 35, when the first conical tooth 32 rotates under the action of the first rotating rod 31, it can realize the transmission of the second conical tooth 35. In turn, the second conical tooth 35 can drive the second rotating rod 34 and the brush plate 36 to rotate, thereby achieving the purpose of cleaning the filter plate 14 by the brush plate 36.
[0032] Working principle: In use, pulling the lever 24 allows it to move inside the movable slot 23. The insert block 25 moves accordingly under the action of the lever 24, separating it from the slot 26. At this time, the spring 27 is in a contracted state, thus releasing the restriction on the connecting block 2. Then, pulling the adsorbent box 12 allows it to be pulled out of the heatless dryer 1, enabling replacement of the adsorbent inside. When the adsorbent box 12 needs to be installed, it is inserted into the heatless dryer 1, and the connecting block 2 moves within the adsorbent box 12. When the connecting block 2 is inserted into the mounting groove 22, the surface of the connecting block 2 and the insert block 25 come into contact, thus squeezing the insert block 25. The insert block 25 then moves into the movable groove 23. At this time, the spring 27 is in a contracted state. When the connecting block 2 slides in and the slot 26 faces the insert block 25, the insert block 25 will be reset under the rebound action of the spring 27. This allows the insert block 25 and the slot 26 to be inserted, thus limiting the connection block 2 and completing the installation and fixing of the adsorbent box 12. At this time, the sealing gasket 28 and the surface of the heatless dryer 1 are tightly attached to achieve a seal.
[0033] The motor 33 is electrically connected to an external power source. The operator starts the motor 33 by pressing the switch. The motor 33 drives the first rotating rod 31 to rotate. The first conical tooth 32 will rotate under the action of the first rotating rod 31 and can transmit power to the second conical tooth 35. The second rotating rod 34 drives the brush plate 36 to rotate under the action of the second conical tooth 35. In turn, the brush plate 36 rotates and rubs against the surface of the filter plate 14, which can clean the filter plate 14 and prevent the filter plate 14 from clogging.
[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
