Description

Technical Field

[0001] This invention relates to the field of grain storage ventilation technology, and in particular to a circulating ventilation system for grain storage. Background Technology

[0002] Grain storage refers to storing grain in specific facilities to maintain its quality and freshness, prevent pests and mold, and ensure food security and continuous supply. During storage, grain is often susceptible to decay or pests due to changes in environment, climate, and ventilation. Therefore, good ventilation and heat dissipation are essential during grain storage. A circulating ventilation system for grain storage is a key component of grain storage. This system is a facility specifically designed for grain storage. Through intelligent control and mechanical operation, it effectively ventilates the grain to maintain its freshness and quality, extending its shelf life.

[0003] In grain storage systems, heat exchange is achieved through circulating ventilation. When ventilation intensity is high, light impurities may enter the ventilation ducts with the airflow and potentially clog the filter screen. As the number of clogged filter screens increases, the ventilation filtration efficiency of the ducts is affected. Therefore, when disassembling, cleaning, or replacing the filter screen, it is necessary to remove and pull it out. To ensure the filtration effect, the gap between the filter screen and the ventilation duct is small. However, light impurities clogging the filter screen may protrude from its position. When pulling out the filter screen, these protruding impurities may restrict its position, affecting replacement. Furthermore, these protruding impurities may come into contact with the edge of the ventilation duct and be impacted and squeezed, causing them to break and fall into the ventilation duct or filter screen mounting slot, potentially damaging the ventilation equipment and the filter screen itself. Therefore, this application provides a circulating ventilation system for grain storage to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a circulating ventilation system for grain storage to solve the problems in existing circulating ventilation devices where protruding light impurities and other blockages may limit the position of the filter screen and affect the replacement of the filter screen. Protruding light impurities may come into contact with the edge of the ventilation duct and be impacted and squeezed, causing the light impurities to break and fall into the ventilation duct or the filter screen installation groove, which may damage the ventilation equipment and the filter screen.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A circulating ventilation system for grain storage includes a ventilation duct, a cleaning component, and a main frame. A placement frame is provided inside the ventilation duct, and the main frame is placed inside the placement frame. A filter screen is provided inside the main frame, and a connecting slot is provided inside the placement frame. The cleaning component includes a first support plate, with connecting arc plates at both ends. The connecting arc plates are fixedly fitted inside the connecting slot, and the first support plate is fixed inside the placement frame by the connecting arc plates. A guide push plate is provided at one end of the first support plate, and an arc-shaped scraper is provided at one end of the guide push plate. A first weakening groove is provided on the inner wall of the guide push plate, a second weakening groove is provided on the inner wall of the arc-shaped scraper, and a scraper weakening groove is provided on the outer wall of the arc-shaped scraper.

[0007] Optionally, the arc-shaped scraper has a plurality of grooves inside, and an arc-shaped support plate is provided inside the grooves. One end of the arc-shaped support plate contacts the outer wall of the first support plate, and the arc-shaped support plate is made of plastic.

[0008] Optionally, the arc-shaped support plate is provided with a baffle weakening groove inside.

[0009] Optionally, the outer wall of the connecting arc plate is provided with a supporting arc plate, the outer wall of the supporting arc plate is in contact with the outer wall of the first support plate, and one end of the supporting arc plate is in contact with the outer wall of the arc-shaped scraper.

[0010] Optionally, the arc-shaped scraper is S-shaped, and the outer wall of the arc-shaped scraper is in contact with the surface of the filter screen.

[0011] Optionally, the guide push plate and the arc-shaped scraper are an integral structure and are made of plastic.

[0012] Optionally, the first support plate and the connecting arc plate are an integral structure and are made of plastic.

[0013] Optionally, the connecting arc plate is M-shaped, and one side of the connecting arc plate is in contact with the outer wall of the main frame.

[0014] Optionally, the outer wall of the connecting arc plate is provided with a limiting groove, and the inside of the connecting groove is provided with a limiting block, the limiting block being fitted inside the limiting groove.

[0015] Optionally, a limiting card is provided on the outer wall of the main frame, and the limiting card is embedded inside the connecting arc plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a cleaning component, not only can the light impurities that are clogged or protruding inside the filter be guided and pushed inward, but the dust attached to the surface of the filter can also be scraped off. This setting ensures that, on the one hand, the light impurities that are protruding restrict the movement of the filter and affect its removal during the filter removal process, and also prevents the light impurities from being squeezed and broken into the filter and ventilation duct. At the same time, it also avoids the problem of light impurities damaging the filter when they break. On the other hand, the arc-shaped scraper pushes the light impurities that are clogged inside the filter inward while scraping off the dust attached to the surface of the filter.

[0018] By setting grooves and arc-shaped support plates in the cleaning components, the arc-shaped support plates can limit the deformation of the arc-shaped scraper, avoiding the problem of poor dust removal effect caused by excessive deformation of the arc-shaped scraper. In addition, the scraped dust can be guided so that the dust falls between the first support plate and the guide push plate, preventing the dust from flying around.

[0019] By setting up a support arc plate, the support arc plate can support the arc-shaped scraper, allowing the arc-shaped scraper to fully contact the filter screen surface. This setting can ensure the scraping effect of the arc-shaped scraper. Attached Figure Description

[0033] like Figures 1 to 4As shown, an embodiment of the present invention provides a circulating ventilation system for grain storage, including a ventilation duct 1, a cleaning component 2, and a main frame 3. A placement frame 5 is provided inside the ventilation duct 1, and the main frame 3 is placed inside the placement frame 5. A filter screen 4 is provided inside the main frame 3, and a connecting slot 10 is provided inside the placement frame 5. The cleaning component 2 includes a first support plate 201, with connecting arc plates 6 at both ends of the first support plate 201. The connecting arc plates 6 are fixedly sleeved inside the connecting slot 10. The first support plate 201 is fixed inside the placement frame 5 by the connecting arc plates 6. A guide push plate 202 is provided at one end of the first support plate 201, and an arc-shaped scraper 203 is provided at one end of the guide push plate 202. The inner wall of the guide push plate 202 is provided with... The first weakening groove 206, the inner wall of the arc-shaped scraper 203 is provided with a second weakening groove 207, the outer wall of the arc-shaped scraper 203 is provided with a scraper weakening groove 208, the arc-shaped scraper 203 is provided with a plurality of grooves 204 inside, the grooves 204 are provided with arc-shaped support plates 205, one end of the arc-shaped support plate 205 contacts the outer wall of the first support plate 201, the arc-shaped support plate 205 is made of plastic, the arc-shaped support plate 205 is provided with a baffle weakening groove 209 inside, the arc-shaped scraper 203 is S-shaped, the outer wall of the arc-shaped scraper 203 contacts the surface of the filter screen 4, the guide push plate 202 and the arc-shaped scraper 203 are an integral structure and are made of plastic, the first support plate 201 and the connecting arc plate 6 are an integral structure and are made of plastic, by setting a cleaning part Part 2: One end of the guide push plate 202 is connected to the first support plate 201, and the other end is connected to the arc-shaped scraper 203. The distance between the guide push plate 202 and the filter screen 4 gradually decreases. The outer wall of the arc-shaped scraper 203 is parallel to the surface of the filter screen 4 and is in contact with it. One end of the arc-shaped support plate 205 is connected to the inside of the groove 204, and the other end is not connected to the outer wall of the first support plate 201. The groove 204 is linearly arranged inside the arc-shaped scraper 203, and the arc-shaped support plate 205 is linearly arranged on the outer wall of the arc-shaped scraper 203 and is set inside the groove 204. The first support plate 201, the guide push plate 202, and the arc-shaped scraper 203 are an integral structure with a certain degree of elasticity. When the filter screen 4 is pulled out, the inside of the filter screen 4 becomes clogged and protruding. Light impurities slide into contact with the surface of the guide push plate 202. As the distance between the guide push plate 202 and the filter screen 4 gradually decreases, the filter screen 4 can be pushed into the interior of the filter screen 4 during the pulling process. This avoids the protruding light impurities restricting the movement of the filter screen 4 and affecting its removal. It also prevents the light impurities from contacting the edge of the placement frame 5 during the pulling process, which could cause the light impurities to break. This also prevents damage to the filter screen 4. At the same time, the supporting arc plate 8 causes the arc scraper 203 to deform at the second weakening groove 207, so that the arc scraper 203 contacts the surface of the filter screen 4 and can scrape off the dust attached to the surface of the filter screen 4 during the pulling process.

[0034] like Figure 4As shown, the connecting arc plate 6 is M-shaped, and one side of the connecting arc plate 6 is in contact with the outer wall of the main frame 3.

[0035] like Figures 1 to 3 As shown, the outer wall of the connecting arc plate 6 is provided with a supporting arc plate 8. The outer wall of the supporting arc plate 8 is in contact with the outer wall of the first support plate 201. One end of the supporting arc plate 8 is in contact with the outer wall of the arc-shaped scraper 203. The outer wall of the connecting arc plate 6 is provided with a limiting groove 7. A limiting block 11 is provided inside the connecting groove 10. The limiting block 11 is fitted inside the limiting groove 7. The outer wall of the main frame 3 is provided with a limiting card 9. The limiting card 9 is fitted inside the connecting arc plate 6. By setting the connecting arc plate 6, the connecting arc plate 6 is connected to the connecting arc plate 6. The fixed arc plate 6 has an "M" structure. The fixed arc plate 6 and the first support plate 201 are an integral structure and are located at both ends of the first support plate 201. During installation, the main frame 3 contacts the outer wall of the fixed arc plate 6 and squeezes the fixed arc plate 6, so that the first support plate 201 is squeezed and fixed inside the connecting slot 10. It can also squeeze and deform the supporting arc plate 8, and can support and fix the arc scraper 203. This setting can ensure the scraping effect of the arc scraper 203.

[0036] The working principle of the technical solution provided by this invention is as follows: When assembling the ventilation duct 1, the cleaning component 2 is fixed to the inside of the connecting slot 10 by the connecting arc piece 6. At the same time, the main frame 3 is placed inside the placement frame 5, and the connecting arc piece 6 is squeezed to fix it inside the connecting slot 10. When it is necessary to disassemble and clean the filter screen 4, by pulling the main frame 3, the light impurities that are blocked or protruding inside the filter screen 4 first slide into contact with the surface of the guide push plate 202. As the distance between the guide push plate 202 and the filter screen 4 gradually decreases, the filter screen 4 moves smoothly during the pulling process. This allows the blockage of light impurities to be pushed into the filter screen 4, preventing protruding light impurities from restricting the movement of the filter screen 4 and affecting its removal. It also prevents light impurities from contacting the edge of the placement frame 5 during the removal of the filter screen 4, thus avoiding breakage. Furthermore, it prevents damage to the filter screen 4 when light impurities are crushed. In addition, the supporting arc plate 8 causes the arc scraper 203 to deform at the second weakening groove 207, allowing the arc scraper 203 to contact the surface of the filter screen 4 and scrape off the dust adhering to the surface of the filter screen 4 during the removal of the filter screen 4.

[0037] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
