DETAILED DESCRIPTION
[0021] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.
[0022] See also Figure 1 The utility model provides an air filter device for a mining machine that is easy to clean and replace, including a purifier body 1, a fan group 2 and a quick loading and unloading mechanism 3. The fan group 2 is installed in the middle of the purifier body 1, and the quick loading and unloading mechanism 3 is provided at the front of the purifier body 1.
[0023] See also Figure 2-6The utility model provides an air filter device for a mining machine that is easy to clean and replace. The quick loading and unloading mechanism 3 includes a connecting frame 31, a storage groove 32, a locking hole 33, a front cover 34, a filter element holder 35, a slot 36, a connecting sleeve 37, a driving roller 38, a wave groove 39, a sliding sleeve 310, a slider 311, a locking tongue 312 and a handle 313. The front part of the purifier body 1 is welded and installed with the connecting frame 31. The left and right sides of the connecting frame 31 are symmetrically provided with storage grooves 32. The bottom surface of the storage groove 32 is provided with a locking hole 33. The front cover 34 is embedded in the inner side of the connecting frame 31. The filter element holder 35 is screwed on the back side of the front cover 34. The longitudinal section of the filter element holder 35 is concave. The top surface of the filter element holder 35 is provided with a slot 36. The air filter element can be inserted into the inner side of the slot 36 and assembled with the filter element holder 35 without the need for screws. The filter element is more convenient to disassemble and install. The connecting sleeve 37 is docked and enters the inner side of the storage groove 32. The driving roller 38 is installed at the upper end of the connecting sleeve 37 for damping rotation. The outer surface of the driving roller 38 is horizontally provided with a wave groove 39. The sliding sleeve 310 is slidably installed at the lower end of the connecting sleeve 37. The sliding sleeve 310 and the connecting sleeve 37 cannot rotate. Sliders 311 are symmetrically provided on the left and right walls of the inner side of the sliding sleeve 310, and the sliders 311 dock and slide with the inner side of the wave groove 39, so that the wave groove 39 can control the sliding sleeve 310 to telescope and slide through the sliders 311. A locking tongue 312 is integrally provided at the bottom of the sliding sleeve 310, and the locking tongue 312 can extend downward from the connecting sleeve 37 and dock and engage with the lock hole 33, so as to lock the connecting sleeve 37 inside the storage groove 32, thereby realizing the installation and fixation of the front cover 34 and the connecting frame 31. The top roller shaft of the driving roller 38 extends upward from the connecting sleeve 37 and is connected and fixed with the handle 313, and the handle 313 is L-shaped.
[0024] Further explanation: the total number of slots 36 is no less than 3, and the overall slots 36 are evenly distributed on the top surface of the filter element holder 35, so that users can easily install activated carbon filter elements, particulate filter elements and other filter elements with different functions at the same time, thereby improving the filtering strength of the purifier body 1.
[0025] It is further explained that the maximum telescopic distance of the lock tongue 312 is not less than 2 cm, ensuring that the lock tongue 312 and the lock hole 33 have sufficient docking length to ensure installation stability.
[0026] Further explanation: the rotation angle range of the drive roller 38 is 90 degrees. When the drive roller 38 is at the maximum rotation angle, the slider 311 is located at the highest point of the wave groove 39. When the drive roller 38 is at the minimum rotation angle, the slider 311 is located at the lowest point of the wave groove 39, allowing the user to accurately control the lock tongue 312 to perform extension and retraction movements.
[0027] It is further explained that when the handle 313 is flipped and snapped into the inner side of the storage groove 32, the drive roller 38 is at the minimum rotation angle, which can hide the handle 313 while the lock tongue 312 is docked and plugged into the lock hole 33, thereby improving the aesthetics and preventing the handle 313 from being accidentally touched and rotated, causing the installation structure to be accidentally unlocked, thereby ensuring installation stability.
[0028] To further illustrate, when the slider 311 is located at the highest point of the wave groove 39 , the locking tongue 312 is completely retracted into the inner side of the connecting sleeve 37 , so that the locking tongue 312 will not hinder the disassembly and assembly process.
[0029] Here's how it works:
[0030] First, remove the front cover 34 and install the air filter. The specific operation method is: flip the handle 313 from the inside of the storage groove 32 to the outside and open it until the drive roller 38 rotates to the maximum angle. During this process, the slider 311 moves upward along the wave groove 39 to the highest point, so that the sliding sleeve 310 drives the lock tongue 312 to retract upward to the inside of the connecting sleeve 37. At this time, the lock tongue 312 is disengaged from the lock hole 33, and the connection and fixation between the front cover 34 and the connecting frame 31 are released. The front cover 34 can be removed from the inside of the connecting frame 31 with the help of the handle 313 to complete the disassembly.
[0031] Second, after the front cover 34 is disassembled, the air filter element can be inserted into the inner side of the slot 36 and assembled with the filter element holder 35 without the need for screws, making the filter element disassembly and assembly more convenient.
[0032] Third, after the filter element is installed, the front cover 34 is reinstalled. The specific operation method is: use the handle 313 to control the front cover 34 to buckle into the inner side of the connecting frame 31. During this process, the connecting sleeve 37 will also dock into the inner side of the receiving groove 32. Finally, the handle 313 is flipped and buckled into the inner side of the receiving groove 32, so that the driving roller 38 rotates to the minimum angle. During this process, the slider 311 moves downward along the wave groove 39 to the lowest point, so that the sliding sleeve 310 drives the locking tongue 312 to extend downward from the inner side of the connecting sleeve 37, and the locking tongue 312 is docked and engaged with the lock hole 33, thereby locking the connecting sleeve 37 inside the receiving groove 32, realizing the installation and fixation of the front cover 34 and the connecting frame 31 without the help of screws. This greatly simplifies the disassembly and assembly process of the front cover 34, facilitates the cleaning and replacement of the filter element, and effectively improves the efficiency of logistics work.
[0033] Fourth, when in use, the purifier body 1 is started to energize the fan unit 2, and the fan unit 2 drives the air flow through the front cover 34, so that the filter element installed on the back of the front cover 34 adsorbs the particulate matter in the air, thereby achieving air purification.
[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
