Description

Technical Field

[0001] This utility model relates to the field of drying device technology, specifically a drying device for a straw combustion furnace. Background Technology

[0002] Returning straw to the field can improve soil and fertilize the land, but due to its high cost, farmers are hesitant to implement it voluntarily. Therefore, the phenomenon of farmers burning straw indiscriminately in fields has persisted for many years, wasting energy and causing serious environmental pollution. To protect the environment and achieve waste utilization, people have invented combustion furnaces specifically for straw burning. Existing straw combustion furnaces discharge the exhaust gas directly through a flue located at the top of the furnace. Since the exhaust gas contains a large amount of heat, directly discharging it not only pollutes the environment but also wastes a significant amount of energy.

[0003] A patent search revealed a document titled "A Drying Device in a Straw Combustion Furnace" (publication number "CN107421274B"). While this device addresses the aforementioned problem, the filter cotton in the device adheres to the surface of harmful particulate matter in the exhaust gas. This particulate matter easily clogs the filter screen, preventing the exhaust gas and heat from smoothly passing through the filter cotton and reaching the straw, thus affecting the straw drying effect. Therefore, this invention designs a drying device in a straw combustion furnace to solve the above problems. Utility Model Content

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] A preferred embodiment of the drying device in the straw combustion furnace provided by this utility model is, for example... Figures 1 to 4The image shows a drying device for a straw combustion furnace, comprising a furnace body 1; a guide sleeve 2 fixedly installed inside the upper part of the furnace body 1; a shell 3 installed on the right side outside the furnace body 1; an installation pipe 4 fixedly installed on the top of the furnace body 1 and passing through the shell 3; a partition 5 fixedly installed inside the shell 3 and fitted outside the installation pipe 4, with an exhaust hole 6 integrally provided at the lower end of the partition 5; and a filter assembly 7 assembled inside the shell 3, which can filter harmful substances generated during the use of the furnace body 1.

[0027] A sliding plate 9 is slidably disposed on the upper part of the shell 3. Baffles 10 are fixedly disposed on the left and right sides inside the sliding plate 9. The filter assembly 7 includes a sleeve 701 rotatably disposed on the middle right side inside the shell 3; a mounting hole 702 integrally disposed inside the sleeve 701; and an activated carbon filter 703 fixedly sleeved on the outside of the sleeve 701.

[0028] It should be noted that the drying devices in existing straw combustion furnaces still have certain shortcomings in actual use. They cannot remove particulate matter adhering to the surface of the filter structure, which prevents heat and exhaust gas from passing through the filter structure smoothly, thus affecting the drying effect of the straw.

[0029] In this embodiment, the worker first places the straw into the upper part of the shell 3, so that the sliding plate 9 supports the straw, and the baffle 10 can prevent the straw from falling into the lower part of the shell 3. Then, by using the furnace body 1, the worker causes the heat and exhaust gas generated by the furnace body 1 to be collected by the guide sleeve 2 and discharged into the lower end of the activated carbon filter 703 through the installation pipe 4 and the exhaust hole 6. At this time, the activated carbon filter 703 filters the harmful particles in the exhaust gas. The filtered exhaust gas and heat pass through the installation hole 702 and the activated carbon filter 703 and then through the baffle 10 to the straw, so that the heat dries the straw.

[0030] In a further preferred embodiment of this utility model, a cleaning component 8 is assembled inside and outside the housing 3. The cleaning component 8 can scrape off particulate matter adsorbed on the outside of the filter component 7. The cleaning component 8 includes a first motor 801 fixedly mounted on the rear end of the outer side of the housing 3; a worm gear 802 rotatably mounted on the top of the first motor 801, and a worm wheel 803 meshing with the outer teeth of the worm gear 802, the worm wheel 803 being fixedly sleeved on the outside of the sleeve 701; a sealing plate 804 fixedly mounted on the lower end of the inner side of the housing 3, and a clearance hole 805 integrally provided inside the sealing plate 804; and a fixed... Inside the lower end of the housing 3, the scraper 806 and the left end of the sealing plate 804 are fixedly connected to the partition 5. The sealing plate 804 has an arc-shaped design, and the center of the sealing plate 804 is concentric with the center of the sleeve 701. The top surface of the sealing plate 804 is in contact with the outer wall of the activated carbon filter 703. The end of the scraper 806 away from the housing 3 is in contact with the surface of the activated carbon filter 703. A box 11 is provided inside the lower end of the housing 3. The box 11 is located below the exhaust hole 6. The first sealing plate 12 is provided on the left side of the front end of the housing 3 through a hinge and on the right side through a latch.

[0031] In this embodiment, the operator turns on the first motor 801. The first motor 801 drives the worm gear 802, which in turn drives the worm wheel 803 to rotate the sleeve 701 and the activated carbon filter 703. At this time, the scraper 806 scrapes off the particles adhering to the surface of the activated carbon filter 703. The scraped particles fall into the housing 11. The sealing plate 804 prevents heat and exhaust gas from being discharged from the left and right sides of the activated carbon filter 703 to the upper part of the housing 3, ensuring the stability of heat and exhaust gas passing through the activated carbon filter 703. The clearance hole 805 provides space for the activated carbon filter 703 to filter exhaust gas. Depending on the actual use, the operator can open the first sealing plate 12 and remove the housing 11 from the inside of the housing 3. Example 2

[0032] Based on Example 1, a preferred embodiment of the drying device in the straw combustion furnace provided by this utility model is, for example... Figures 1 to 4 As shown: A shaped rod 13 is fixedly provided at the top center of the slide plate 9. The shaped rod 13 slides through the housing 3 and is slidably connected to the partition plate 5. A drive assembly is provided outside the partition plate 5. The drive assembly can control the slide plate 9 to move along the longitudinal direction of the housing 3. The drive assembly includes a second motor 14 fixedly provided at the upper left side of the partition plate 5; a crankshaft 15 fixedly provided at the left side of the second motor 14; a push plate 16 rotatably sleeved outside the crankshaft 15, and the push plate 16 rotatably sleeved outside the shaped rod 13. The end of the crankshaft 15 away from the second motor 14 is rotatably connected to the housing 3. A second sealing plate 17 is provided at the lower end of the housing 3 by hinge and at the upper end by latch.

[0033] In this embodiment, the operator can turn on the second motor 14. The second motor 14 drives the crankshaft 15, which in turn drives the push plate 16, the shaped rod 13, and the slide plate 9 to move up and down repeatedly along the longitudinal direction of the housing 3. This causes the slide plate 9 to shake the straw, improving the effect of sufficient contact between the straw and heat. Depending on the actual use, the operator can open the second sealing plate 17 to remove the dried and burned straw from inside the housing 3.

[0034] In summary, this application, through its cleaning function design, can scrape off particulate matter adhering to the surface of the activated carbon filter, ensuring the drying effect of the straw. Through a mechanical linkage design, simply activating the second motor causes the sliding plate, along with the straw, to vibrate inside the casing, ensuring full contact between the straw and the heat generated by the furnace body, further improving the straw drying effect.
