Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a temperature control equipment for grain storage warehouses. Background Technology

[0002] Grain reserves are an important infrastructure for ensuring national food security. To ensure the long-term safe storage of grain, it is necessary to strictly control the temperature and humidity inside the grain warehouse to prevent grain from becoming moldy, infested with pests, and deteriorating in quality. For this reason, grain warehouses are generally equipped with temperature control equipment, such as cooling or air exchange through ventilation systems, to maintain a suitable grain storage environment.

[0003] During the long-term operation of temperature control equipment, the air filter will inevitably absorb a large amount of dust and impurities. If it is not cleaned for a long time, it will cause the filter to become clogged. The clogged filter will directly reduce the ventilation volume, reduce the heat dissipation or ventilation efficiency of the temperature control equipment, increase the energy consumption of the equipment, and may even cause the equipment to overheat and be damaged due to poor ventilation, thus affecting the temperature control effect of the grain depot.

[0004] To solve the above problems, the filter screen needs to be disassembled, cleaned, and reinstalled regularly. However, the existing temperature control equipment usually uses bolts or a relatively complex clip structure to fix the filter screen. When performing maintenance, the operator must carry the corresponding tools to loosen or pry open the fasteners one by one to remove the filter screen. The whole process is not only cumbersome and time-consuming, but also in the dusty or space-constrained environment of grain depots, the use of tools is inconvenient, and small parts such as bolts are easy to lose. This greatly increases the difficulty of maintenance work and the downtime of equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a temperature control device for grain storage warehouses, aiming to improve the problems of cumbersome disassembly and maintenance of the filter screen and poor sealing after replacement in the existing temperature control device for grain storage warehouses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature control device for grain storage warehouses, comprising: a box body, a fan, a fixed frame, and a filter screen that slides in conjunction with the fixed frame; and a disassembly mechanism.

[0007] The disassembly mechanism further includes a first fixed housing and a second fixed housing; The disassembly mechanism includes a baffle, a sliding column driven by a first spring, a pressing rod, and a linkage mechanism connecting the pressing rod and the sliding column.

[0008] Furthermore, the baffle is fixedly installed on the fixed frame to block the filter screen, and the sliding column is movably configured to restrict the baffle in the locked position. When the pressing rod is pressed, the linkage mechanism drives the sliding column to move from the locked position to the unlocked position against the elastic force of the first spring.

[0009] Preferably, the linkage mechanism includes a lever disposed on the inner wall of the first fixed shell, and a first sliding rod connected between the lever and the sliding column; the pressing rod abuts against the lever.

[0010] Preferably, the lever is rotatably connected to the inner wall of the first fixed housing via a fixed shaft; the disassembly mechanism further includes a torsion spring, which is sleeved on the fixed shaft and used to drive the lever to reset.

[0011] Preferably, the disassembly mechanism further includes a fixing block, which is fixed to the fixing frame and used to support the baffle during installation.

[0012] Preferably, the temperature control equipment for the grain storage warehouse further includes an adaptive sealing mechanism; the adaptive sealing mechanism includes a sealing gasket slidably connected to the inner wall of the fixed frame and a second spring for elastically pushing the sealing gasket toward the filter screen.

[0013] Preferably, the adaptive sealing mechanism further includes a fixed post and a push rod; the fixed post is fixed to the fixed frame, the push rod is slidably engaged with the fixed post, the second spring is housed in the fixed post and abuts against the push rod, and the sealing gasket is fixed to one end of the push rod.

[0014] Preferably, the pressing rod is slidably connected to the first fixed shell, and the sliding column is slidably engaged with the second fixed shell.

[0015] Preferably, the disassembly mechanism further includes a second sliding rod, one end of the pressing rod abutting against the lever, and the other end of the pressing rod abutting against the second sliding rod.

[0016] This utility model has the following beneficial effects: In this invention, by setting up a disassembly mechanism that links a pressing rod, a lever, and a sliding column, the operator only needs to press the pressing rod to move the sliding column to unlock the baffle. This solves the problems of cumbersome filter screen disassembly and assembly, reliance on tools, and time and effort in the prior art, and achieves the technical effect of simplifying maintenance operations and realizing quick tool-free disassembly and assembly of the filter screen.

[0017] In this invention, by setting an adaptive sealing mechanism with a second spring and a push rod, the continuous elastic force of the spring keeps the sealing gasket tightly pressed against the filter screen, which solves the problem in the prior art that the filter screen is not sealed properly due to repeated disassembly and assembly, manufacturing tolerances, or aging of the sealing components, thus affecting the temperature control efficiency. It achieves the technical effect of automatically compensating for the sealing gap and ensuring the long-term, efficient and stable operation of the equipment. Attached Figure Description

[0020] 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.

[0021] Please refer to Figures 1 to 4 This utility model provides a temperature control device for grain storage warehouses, aiming to solve the problems of cumbersome disassembly and maintenance of filter screens and poor sealing after replacement in the existing temperature control devices for grain storage warehouses.

[0022] The temperature control equipment for the grain storage warehouse includes a housing 1, a fan 2, a fixing frame 406, and a filter screen 405. The fan 2 is installed in the housing 1, the fixing frame 406 is fixedly connected to the housing 1, and the filter screen 405 is slidably fitted inside the fixing frame 406. The temperature control equipment for the grain storage warehouse also includes a disassembly mechanism 3 for quickly disassembling and assembling the filter screen 405.

[0023] The disassembly mechanism 3 enables convenient locking and unlocking of the filter screen 405. The disassembly mechanism 3 specifically includes a baffle 311, a sliding column 307, a first spring 308, a pressing rod 301, and a linkage mechanism. The baffle 311 is fixedly installed on the fixed frame 406 and is used to block the filter screen 405 in the installed state. The sliding column 307 is movably set by the drive of the first spring 308. When the sliding column 307 is not subjected to external force, it extends to the locked position and restricts the baffle 311 in the locked position. The pressing rod 301 is operably set inside the first fixed shell 302. The linkage mechanism is connected between the pressing rod 301 and the sliding column 307. When the pressing rod 301 is pressed, the linkage mechanism will transmit the pressing force and drive the sliding column 307, so that the sliding column 307 can overcome the elastic force of the first spring 308 and move from the locked position to the unlocked position, thereby releasing the restriction on the baffle 311.

[0024] The linkage mechanism includes a lever 303 and a first sliding rod 306. The lever 303 is rotatably connected to the inner wall of the first fixed shell 302 via a fixed shaft 304. One end of the first sliding rod 306 is connected to the lever 303, and the other end of the first sliding rod 306 is connected to the sliding column 307. The pressing rod 301 abuts against the lever 303, thus forming a complete force transmission path. To ensure that the lever 303 can automatically reset, the disassembly mechanism 3 also includes a torsion spring 305. The torsion spring 305 is sleeved on the fixed shaft 304, and the two ends of the torsion spring 305 abut against the lever 303 and the inner wall of the first fixed shell 302, respectively, to provide a reset force for the entire disassembly mechanism 3.

[0025] To ensure the stability of the baffle 311 during installation, the disassembly mechanism 3 also includes a fixing block 312, which is fixed to the fixing frame 406 and is used to effectively support the baffle 311 during installation, providing an installation reference for each moving part. The disassembly mechanism 3 is also provided with a first fixing shell 302 and a second fixing shell 309. The pressing rod 301 is slidably connected to the first fixing shell 302, the sliding column 307 is slidably engaged with the second fixing shell 309, and the first spring 308 is housed inside the second fixing shell 309. The disassembly mechanism 3 also includes a second sliding rod 310, one end of the pressing rod 301 abuts against the lever 303, and the other end of the pressing rod 301 abuts against the second sliding rod 310.

[0026] The adaptive sealing mechanism 4 includes a fixed post 401, a second spring 402, a push rod 403, and a sealing gasket 404. The fixed post 401 is fixedly connected to the inner wall of the fixed frame 406. The push rod 403 is slidably fitted inside the fixed post 401. The second spring 402 is housed in the fixed post 401 as an elastic element and always applies an elastic thrust to the push rod 403. The sealing gasket 404 is fixed to the end of the push rod 403 away from the second spring 402. The sealing gasket 404 of the adaptive sealing mechanism 4 surrounds the opening edge of the sliding path of the filter screen 405, thereby forming a circumferential seal.

[0027] In the assembled state, when the filter screen 405 slides into the inner wall of the fixed frame 406, the side wall of the filter screen 405 will squeeze the sealing gasket 404. At this time, it will push the push rod 403 to compress the second spring 402, so that the push rod 403 can slide inside the fixed post 401. Under the reaction force of the second spring 402, the push rod 403 will constantly press against the sealing gasket 404, so that the sealing gasket 404 can always fit tightly against the filter screen 405. This sealing structure with elastic compensation ensures that even if the filter screen 405 has manufacturing tolerances or the sealing gasket 404 wears out after long-term use, the two can still maintain effective airtightness and prevent air leakage.

[0028] To ensure that the disassembly mechanism 3 and the adaptive sealing mechanism 4 are arranged reasonably and do not interfere with each other, the disassembly mechanism 3 is located at the end of the fixed frame 406 along the sliding direction of the filter screen 405, and the adaptive sealing mechanism 4 is located on the side wall of the fixed frame 406 along the sliding direction of the filter screen 405. This arrangement allows the operator to easily access the pressing rod 301 when disassembling the filter screen 405, while the adaptive sealing mechanism 4 can continuously provide lateral sealing force throughout the entire sliding and installation process of the filter screen 405.

[0029] To facilitate the precise installation and guidance of the filter screen 405, the inner wall of the fixing frame 406 is provided with a groove for guiding and accommodating the filter screen 405. The edge of the filter screen 405 can slide in the groove to prevent skewing during the installation process.

[0030] To facilitate disassembly, the baffle 311 has an inclined surface at the position where it contacts the sliding post 307. When the baffle 311 is installed, the inclined surface can smoothly press down and push the sliding post 307 open. After the baffle 311 is fully in place, the sliding post 307 can automatically pop out and lock the baffle 311 under the action of the first spring 308, realizing the convenient operation of "pushing in and locking".

[0031] To improve the sealing effect, the surface of the sealing gasket 404 of the adaptive sealing mechanism 4 that contacts the filter screen 405 is covered with the filter screen 405.

[0032] Working principle: When the temperature control equipment is in normal use, the fan 2 conducts heat out of the box 1, and the air flows through the filter screen 405. The second spring 402 of the adaptive sealing mechanism 4 pushes the push rod 403, so that the push rod 403 can slide inside the fixed column 401, thereby making the push rod 403 continuously push the sealing gasket 404, so that the sealing gasket 404 tightly fits the side wall of the filter screen 405, ensuring the airflow channel is sealed. When the filter screen 405 needs to be cleaned and maintained, it can be done through the disassembly mechanism 3. The operator first presses the pressing rod 301, which slides inside the first fixed housing 302. At this time, one end of the pressing rod 301 exerts pressure on the second sliding rod 310, causing the second sliding rod 310 to slide. The other end of the pressing rod 301 exerts pressure on the lever 303, causing the lever 303 to rotate around the fixed shaft 304. When the lever 303 rotates, it overcomes the torque of the torsion spring 305. The other end of the lever 303 exerts an upward pushing force on the first sliding rod 306. The first sliding rod 306 then drives the sliding column 307 to slide inside the second fixed housing 309 and compress the first spring 308. After the sliding column 307 retracts, its head is freed from the restriction of the baffle 311. At this time, the baffle 311 can be removed and the filter screen 405 can be slid out along the groove for maintenance. When installing the filter screen 405, first slide the filter screen 405 into the fixing frame 406 along the groove, then put the baffle 311 back in its original position. Under the support and fixation of the fixing block 312, the baffle 311 presses against the sliding column 307 with the inclined surface, causing the first spring 308 to be passively compressed. When the baffle 311 is fully in place, the sliding column 307 automatically pops out under the elastic force of the first spring 308, and re-limits and locks the baffle 311, thus completing the installation process.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
