Technical Field

[0001] The utility model relates to the technical field of screening equipment, and particularly relates to an efficient dewatering screen. Background Art

[0002] In industries such as metallurgy, mining, chemical engineering, and construction, a large amount of raw materials and recyclable waste materials need to be processed by sand making machines and sand washing equipment. The raw materials are crushed by the sand making machine to the particle size required for the next operation, and then washed by the sand washing equipment to meet the usage requirements. After washing, the raw materials will be dehydrated by a dewatering screen. The main functions of the dewatering screen are dehydration, de-sludging, and de-mediuming, as well as the recovery of fine sand or washed sand in the raw materials, etc.

[0003] The dewatering screen is a special equipment for dehydration operations, and is widely applicable to the processes of coal, mud, and sand recovery, coarse separation by pressure filtration, coarse separation by filtration, and dehydration and recovery of other extremely fine materials. At present, vibration motors are used as excitation sources for dewatering screens on the market;

[0004] After searching the prior art for "a new type of efficient dewatering screen" with the publication number "CN214763779U", the exciter of this device uses thin oil lubrication, which is more conducive to heat dissipation and convenient for maintenance. However, the sieve plates inside the dewatering screen will be worn, blocked, and cracked, and the sieve plates need to be replaced to maintain the stable screening efficiency of the dewatering screen. The traditional sieve plates of the dewatering screen are mostly installed in a fixed structure, which is inconvenient to replace.

[0005] Therefore, an efficient dewatering screen is proposed to solve the above problems. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-4 shown, a high-efficiency dewatering screen includes: a dewatering screen box body 1, a vibration motor 11 is fixedly connected to the upper end of the dewatering screen box body 1, a plurality of buffer bases 12 are fixedly connected to the lower end of the dewatering screen box body 1, and a sieve plate 2 is arranged inside the dewatering screen box body 1; two replacement mechanisms 3, the replacement mechanisms 3 are arranged on both sides of the dewatering screen box body 1, and the replacement mechanisms 3 extend into the dewatering screen box body 1; wherein, the replacement mechanism 3 includes a buckle assembly 31 arranged inside the dewatering screen box body 1, the surface of the buckle assembly 31 extends to the outside of the dewatering screen box body 1, and a positioning component 32 is installed on the side of the buckle assembly 31 away from the dewatering screen box body 1;

[0024] As Figures 1-4As shown in the figure, the buckle assembly 31 includes a rotating shaft 312 rotatably connected to the inner wall of the dewatering screen box body 1. Both ends of the rotating shaft 312 penetrate to the outside of the dewatering screen box body 1. A dust-proof shell 311 is sleeved on the surface of the rotating shaft 312. The dust-proof shell 311 is fixedly connected to the outside of the dewatering screen box body 1. A worm gear 313 is rotatably connected to the inner bottom wall of the dust-proof shell 311. A worm 314 is fixedly connected to the surface of the rotating shaft 312. The worm 314 is meshed with the worm gear 313. A sliding rod 315 is slidably connected to the inside of the dust-proof shell 311. One end of the sliding rod 315 close to the vibration motor 11 is fixedly connected to a buckle seat 316. A tooth 317 is fixedly connected to the inner wall of the buckle seat 316. The tooth 317 is clamped with the edge of the sieve plate 2. A spur gear 319 is fixedly connected to the upper end of the worm gear 313. A rack 318 is fixedly connected to one side of the sliding rod 315. The spur gear 319 is meshed with the rack 318;

[0025] When the device is in use, the rotating shaft 312 can be driven to rotate synchronously by manually operating the rotating head 321. At this time, the rotating shaft 312 drives the worm 314 to rotate accordingly. Then, under the action of meshing connection, the worm gear 313 is driven to rotate synchronously. At this time, the worm gear 313 drives the spur gear 319 to rotate synchronously. Furthermore, the rack 318 meshed with it drives the buckle seat 316 to move synchronously through the sliding rod 315. The teeth 317 in the buckle seat 316 are used to position sieve plates 2 of different sizes, facilitating the quick replacement operation of the sieve plate 2;

[0026] As Figure 1 、 Figure 2 and Figure 4 shown, the positioning assembly 32 includes a rotating head 321 rotatably connected to the surface of the dust-proof shell 311 and a flexible buffer plate 323 fixedly connected to the side of the dust-proof shell 311.

[0028] When the utility model is in use, the manual rotation of the rotating head 321 causes the lever 322 to rotate synchronously. At this time, when the rotation reaches the position, the positioning sleeve 324 drops, and the inner groove 325 passes through the end of the adjacent lever 322 to complete the positioning. The rotating head 321 drives the rotating shaft 312 to rotate synchronously, the rotating shaft 312 drives the worm 314 to rotate accordingly, and the worm 314 drives the worm wheel 313 to rotate synchronously. At this time, the worm wheel 313 drives the spur gear 319 to rotate synchronously, and the rack 318 engaged with it drives the buckle seat 316 to move synchronously through the sliding rod 315. The teeth 317 in the buckle seat 316 are used to position the sieve plates 2 of different sizes, which facilitates the quick replacement operation of the sieve plates 2.
