Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen with dustproof effect. Background Technology
[0002] Vibrating screens are highly efficient material screening equipment widely used in mining, metallurgy, chemical, food, building materials and other industries. They are mainly used for classifying, screening and filtering various granular or powdery materials according to particle size. This equipment can process large quantities of materials quickly and continuously, and features high screening efficiency, strong adaptability and stable operation. It plays an important role in modern production lines and can meet the fine classification requirements of different industries.
[0003] However, vibrating screens also have some obvious problems in actual use: Because the material jumps and tumbles continuously on the screen surface during screening, and the vibration causes strong disturbance between the material and the air, a large amount of dust is easily generated at the screening site. This dust problem is particularly prominent when screening dry, powdery materials, not only polluting the working environment and affecting the health of operators, but also causing material loss and environmental pollution. Furthermore, flying dust increases equipment wear, accelerates component aging, and may even cause safety hazards such as dust explosions. Additional dust removal equipment is needed to ensure safe production, increasing operating costs and management difficulty. Utility Model Content

[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 see Figure 1-4 A dustproof vibrating screen includes a main body 1, a screen box 2 at the upper end of the main body 1, a cover 3 at the upper end of the screen box 2, a mounting base 4 fixedly connected inside the cover 3, a filter screen 41 slidably connected inside the mounting base 4, a fan 42 fixedly installed inside the mounting base 4, a sleeve 43 fixedly connected to the outer side of the mounting base 4, a fixing plate 44 fixedly connected inside the sleeve 43, and a locking rod 45 slidably connected inside the fixing plate 44.
[0022] Please see Figure 2-4 The locking rod 45 is slidably connected to the mounting base 4 and the filter screen 41. The locking rod 45 is designed to limit the position of the filter screen 41. A baffle 46 is fixedly connected to the outside of the locking rod 45. The baffle 46 is in contact with the mounting base 4 and is slidably connected to the sleeve 43. The baffle 46 is designed to limit the position of the locking rod 45. A spring 47 is provided on the outside of the locking rod 45. One end of the spring 47 is in contact with the fixing plate 44 and the other end of the spring 47 is in contact with the baffle 46. A pull plate 48 is fixedly connected to the end of the locking rod 45 away from the filter screen 41. The pull plate 48 is in contact with the fixing plate 44. A limit mechanism 5 is provided on the cover 3.
[0023] Please see Figure 2-4The limiting mechanism 5 includes a limiting plate 51. The outer side of the cover 3 contacts the limiting plate 51, and the outer side of the sieve box 2 is fixedly connected to a limiting block 52. The limiting plate 51 contacts the sieve box 2, and the limiting plate 51 and the limiting block 52 are slidably connected. Through the design of the limiting plate 51, the cover 3 can be limited. A guide rod 53 is fixedly connected to the side of the limiting plate 51 near the cover 3. The guide rod 53 is slidably connected to the cover 3. A threaded rod 54 is rotatably connected inside the limiting plate 51. The threaded rod 54 is connected to the cover. The cover 3 is connected by a threaded connection. A retaining ring 55 is fixedly connected to the outside of the threaded rod 54. The retaining ring 55 contacts the limiting plate 51 and is movably connected to the cover 3. The design of the retaining ring 55 allows the threaded rod 54 to drive the limiting plate 51 to move. A knob 56 is fixedly connected to the end of the threaded rod 54 away from the cover 3. The knob 56 contacts the limiting plate 51. The design of the knob 56 allows the threaded rod 54 to be rotated easily. The design of the limiting mechanism 5 allows the cover 3 to be disassembled easily.
[0024] The specific implementation process of this utility model is as follows: When in use, by starting the fan 42, the fan 42 draws air into the cover 3, and the airflow drives the dust in the sieve box 2 to flow. The airflow is filtered by the filter screen 41 and then drawn away by the fan 42, which can isolate the dust at the lower end of the filter screen 41 and prevent the dust from flying.
[0025] By rotating the knob 56, the threaded rod 54 rotates, causing the threaded rod 54 to move threadedly with the cover 3. This allows the threaded rod 54 to move inside the cover 3, which in turn moves the limiting plate 51, causing the limiting plate 51 to slide off the limiting block 52. This releases the restriction on the cover 3, allowing it to be disassembled. By moving the pull plate 48 away from the filter screen 41, the pull plate 48 moves the locking rod 45, which in turn moves the baffle 46. This causes the baffle 46 to press against the spring 47, and the locking rod 45 to slide out of the filter screen 41. This releases the restriction on the filter screen 41, allowing it to be disassembled and cleaned.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
