Description

Technical Field

[0001] This utility model relates to the field of tube bundle dryer technology, specifically to a waste heat utilization component for a tube bundle dryer. Background Technology

[0002] A tube bundle dryer is a drying device that primarily uses heat conduction. Its core structure consists of several parallel tube bundles. A heat medium (such as steam or heat transfer oil) flows inside the tube bundles, while the material to be dried is on the outside. During operation, the material moves outside the tube bundles, and the heat medium transfers heat to the material through the tube walls, causing the moisture in the material to evaporate and be carried away by the airflow, thus achieving the drying purpose. The equipment is usually equipped with a rotating device (such as a lifting plate or agitator) to promote uniform distribution of the material and ensure full contact with the tube bundles, improving drying efficiency. Tube bundle dryers are used in a wide range of industries, including chemical, food and agricultural product processing, pharmaceutical, environmental solid waste treatment, mining and metallurgy, and building materials. They are suitable for drying various materials such as inorganic salts, grains, pharmaceutical intermediates, sludge, metal ore powder, and cement raw materials.

[0003] Existing patent application CN202221351513.3 discloses a waste heat recovery and utilization device for a tube bundle dryer, including a waste heat recovery machine. The waste heat recovery machine has a storage tank inside, and an exhaust connection pipe is fixedly installed on the rear surface of the waste heat recovery machine. A corn tube bundle dryer is movably connected to the lower surface of the waste heat recovery machine. A circulating water pump is fixedly installed on the bottom surface inside the storage tank. A first heating pipe is fixedly installed at the output end of the circulating water pump, and the other end of the first heating pipe is fixedly connected to a corn conveying pipe. A guide hole is opened inside the corn conveying pipe, and the guide hole communicates with the inside of the first heating pipe. When corn is conveyed through the corn conveying pipe, starting the circulating water pump will deliver heated water through the first heating pipe to the guide hole. When the guide hole is filled with heated water, it will heat the corn conveying pipe body, thereby transferring heat to the conveyed corn, heating the corn to be dried, and reducing the corn drying time.

[0004] The above solution has the following problems during implementation: hot air from the corn tube dryer is drawn into the waste heat recovery machine by an exhaust fan. Since the dried corn kernels are relatively light and contain some corn cobs, a small portion of the corn kernels and corn cobs are easily drawn into the exhaust fan during the exhaust process, which can easily damage the fan blades and affect the normal operation of the exhaust fan. Therefore, a waste heat utilization component for the tube dryer is needed to solve the above problems. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4As shown, this utility model provides a technical solution: a waste heat utilization component for a tube bundle dryer, including a tube bundle dryer 1, a feed hopper 101 fixedly connected to the side end of the tube bundle dryer 1, a waste heat recovery box 2 fixedly installed at the top end of the tube bundle dryer 1, a bent pipe 201 fixedly connected to the side end of the waste heat recovery box 2, an exhaust fan installed inside the bent pipe 201, a filter box 3 fixedly connected to the bottom end of the bent pipe 201, an installation groove 301 opened on the side end of the filter box 3, a filter assembly 4 inserted inside the installation groove 301, and a limiting component 5 for fixing the filter assembly 4 on the side end of the filter box 3. The feed hopper 101 can be used to... Rice grains are fed into the tube bundle dryer 1 for drying. During the drying process, the hot air is drawn into the waste heat recovery box 2 through the exhaust fan in the bent pipe 201 for recycling. The limiting component 5 facilitates the fixing of the filter component 4 in the filter box 3, and also facilitates the quick disassembly and cleaning of the filter component 4. The filter component 4 can intercept the corn kernels and corn cobs that are drawn up at the bottom of the filter component 4. This can prevent a small part of the corn kernels and corn cobs from being drawn into the exhaust fan during the exhaust process, thus avoiding damage to the exhaust fan blades and preventing the normal operation of the exhaust fan.

[0018] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, the filter assembly 4 includes a filter plate 401, which is inserted into the mounting groove 301. A sealing ring 402 is fixedly connected to the outer end of the filter plate 401. A groove 403 is provided on the side end of the filter plate 401, and an insertion hole 404 is provided on the top end of the filter plate 401. A sealing groove 302 is provided on the side end of the filter box 3. The sealing ring 402 is adapted to the sealing groove 302. In practice, when the exhaust fan in the bend 201 draws the hot air in the tube bundle dryer 1 into the waste heat recovery box 2, the filter plate 401 can intercept the drawn-up corn kernels and corn cobs at the bottom end of the filter plate 401. This can prevent a small portion of corn kernels and corn cobs from being drawn into the exhaust fan during the exhaust process, thus preventing damage to the fan blades and avoiding affecting the normal use of the exhaust fan.

[0019] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the limiting component 5 includes an extension plate 501, which is fixedly connected to the side of the filter box 3. An insertion rod 502 is inserted between the top and bottom of the extension plate 501. A pull head 503 is fixedly connected to the top of the insertion rod 502. A fixing plate 504 is fixedly connected to the outer end of the insertion rod 502. A spring 506 is sleeved on the outer end of the insertion rod 502. The bottom end of the spring 506 is fixedly connected to the top of the fixing plate 504, and the top end of the spring 506 is fixedly connected to the bottom end of the extension plate 501. A sliding groove 303 is provided on the side of the filter box 3 for fixing... A slider 505 is fixedly connected to the side end of plate 504. The slider 505 is slidably connected in the groove 303. The insertion rod 502 is adapted to the insertion hole 404. In practice, the insertion rod 502 is inserted into the insertion hole 404 to fix the filter plate 401 in the mounting groove 301 of the filter box 3. At this time, the sealing ring 402 is also tightly locked in the sealing groove 302 to prevent hot air from escaping from the bend 201. When it is necessary to clean the filter plate 401, the pull head 503 is pulled upward. At this time, the pull head 503 drives the insertion rod 502 and the fixed When plate 504 moves upward, slider 505 slides within groove 303 to limit the position of fixed plate 504. At this time, the upward movement of fixed plate 504 compresses spring 506, causing it to retract. After insert rod 502 leaves the insertion hole 404 at the top of filter plate 401, pulling groove 403 allows filter plate 401 to be easily pulled out of mounting groove 301, facilitating quick disassembly of filter plate 401 and easy cleaning of corn kernels and ears from it. After cleaning, filter plate 401 can be reassembled. Insert the rod into the mounting slot 301. At this time, the sealing ring 402 is inserted into the sealing slot 302. Then, the insertion hole 404 is aligned with the position of the insertion rod 502. After releasing the pull head 503, the spring 506 pushes against the fixing plate 504 and drives the insertion rod 502 to move down. At this time, the insertion rod 502 is reinserted into the insertion hole 404 to limit and fix the filter plate 401, which facilitates the quick fixing and installation of the filter plate 401. At this time, when the exhaust fan in the bend 201 continues to draw hot air, the filter plate 401 can continue to filter corn kernels and corn ears.

[0020] Working principle: The filter plate 401 is fixed in the mounting groove 301 of the filter box 3 by inserting the rod 502 into the insertion hole 404. At this time, the sealing ring 402 is also tightly locked in the sealing groove 302 to prevent hot air from escaping from the bend 201. When the exhaust fan in the bend 201 draws the hot air from the tube bundle dryer 1 into the waste heat recovery box 2, the filter plate 401 intercepts the drawn-up corn kernels and ears at the bottom of the filter plate 401. This prevents a small portion of corn kernels and ears from being drawn into the exhaust fan during the exhaust process, thus avoiding damage to the exhaust fan blades and preventing affecting the normal operation of the exhaust fan. When it is necessary to clean the filter plate 401, the pull head 503 is pulled upward. The pull head 503 moves the rod 502 and the fixing plate 504 upward. At this time, the slider 505 slides in the sliding groove 303 to limit the position of the fixing plate 504. The fixed plate 504 moves upward to compress the spring 506 and retract. At this time, after the insertion rod 502 leaves the insertion hole 404 at the top of the filter plate 401, the filter plate 401 can be easily pulled out of the mounting groove 301 by pulling the pull groove 403. This facilitates quick disassembly of the filter plate 401 and also makes it easier to clean the corn kernels and ears of corn on the filter plate 401. After cleaning, the filter plate 401 is reinserted into the mounting groove 301. At this time, the sealing ring 402 is inserted into the sealing groove. Inside the sealing groove 302, the insertion hole 404 is aligned with the insertion rod 502. After releasing the pull head 503, the spring 506 pushes against the fixing plate 504, causing the insertion rod 502 to move down. At this time, the insertion rod 502 is reinserted into the insertion hole 404 to limit and fix the filter plate 401, thus facilitating the quick fixing and installation of the filter plate 401. When the exhaust fan in the bend 201 continues to draw hot air, the filter plate 401 can continue to filter the corn kernels and corn cobs.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
