Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] refer to Figure 1-4A new type of box-type self-synchronous dewatering screen is shown, including a dewatering screen body 1 and a driving mechanism 6.

The side panels 2 are also provided with a first lifting ring 4 and a second lifting ring 5 for facilitating the transfer of equipment. Connecting beams are provided between the two groups of first lifting rings 4 and the two groups of second lifting rings 5. A drainage device is provided at the feed port of the dewatering screen body 1. The drainage device includes an overflow plate 8, and the overflow plate 8 is connected to the rear end of the side panel 2. The front end of the side panel 2 is connected to an extension plate 21, and the extension plate 21 is located below the screen frame. In order to make it easier for the equipment to vibrate and dehydrate the material, a mounting beam 71 for fixing the box-type vibrator 7 is provided between the first lifting ring 4 and the second lifting ring 5. The mounting beam 71 is provided Located at the upper front section of the side plate 2, the box-type vibrator 7 has a transmission shaft inside, and eccentric cams are connected to both ends of the transmission shaft. There are two groups of transmission shafts, and the two groups of transmission shafts rotate independently of each other. In order to make the vibration effect of the dewatering screen body 1 better, the box-type vibrator 7 is driven by a driving mechanism 6. The driving mechanism 6 includes a mounting frame 61 and two groups of driving motors 64 adapted to the position of the transmission shaft. The mounting frame 61 is provided with a first platform 62 and a second platform 63 for installing the two groups of driving motors 64. The position of the driving motor 64 on the second platform 63 is higher than that of the driving motor 64 on the first platform 62. The two groups of driving motors 64 are connected to the transmission shafts corresponding to their positions through driving shafts 65, so that the box-type vibrator 7 can be driven by two groups of driving motors 64 at the same time, so that it has double the power source during operation, thereby being able to generate a stronger exciting force and enhance the vibration effect.

[0025] As an implementation method in this embodiment, in order to balance the elastic forces at the front and rear ends of the equipment, the spring support mechanism 3 also includes a front support and a rear support. The elastic force of the front support is greater than the elastic force of the rear support. The tops of the front support and the rear support are both connected with connecting parts 33 for connecting to the side panels 2. The front support is located below the first hanging ring 4, and the rear support is arranged below the second hanging ring 5. Four groups of springs are arranged in the front support, and three groups of springs are arranged in the rear support. By arranging different numbers of springs in the front support and the rear support, the effect of front and rear load balancing during equipment operation is achieved, thereby extending the service life of the dewatering screen.

[0026] As an implementation method in this embodiment, in order to improve the strength of the side panel 2, the outer top edge of the side panel 2 is connected with a first reinforcing plate 9 and a second reinforcing plate 10, and the first reinforcing plate 9 and the second reinforcing plate 10 match the top edge shape of the side panel 2, and the first reinforcing plate 9 and the second reinforcing plate 10 are respectively installed at the front and rear of the outer side of the mounting beam 71, and an internal reinforcing plate is provided in the side panel 2 for strengthening the internal structure. In order to make the maintenance or expansion of the equipment more convenient and quick, the sieve plate also includes a modular sieve plate 11, and the sieve plate is spliced ​​by multiple groups of modular sieve plates 11, so that when the modular sieve plate 11 needs to be maintained and replaced, the piece that needs to be maintained can be replaced separately, and when the sieve plate needs to be used on a dewatering screen of a larger volume, it can be More modular sieve plates 11 are spliced ​​into sieve plates of different sizes, which is flexible and changeable. When the existing dewatering screen is output, a discharge plate is usually set at the discharge port to adjust the output position, so that the material can be directly output to the unloading belt, which occupies a large area. The front end of the sieve plate is flush with the side plate 2, so that the space below the front end discharge of the dewatering screen is expanded, and the unloading belt can be directly laid under the extension plate 21. The bottom of the overflow plate 8 is in contact with the top surface of the sieve plate. Because the front end of the sieve plate is flush with the side plate 2, the equipment does not need to use the discharge plate to output the material to the unloading belt, which makes the equipment design more compact. While the footprint remains unchanged, the working distance of the sieve plate is extended, and the unloading belt is easier to lay.

[0027] The working principle of the utility model is as follows: when it is necessary to dehydrate the material, the unloading belt is first laid to the bottom of the extension plate 21, so that the material can be directly output to the unloading belt, and then the equipment is started, and the driving motor 64 is started. The two sets of driving motors 64 drive the two sets of transmission shafts in the box-type vibrator 7 to rotate through the driving shaft 65, and the two sets of transmission shafts drive the eccentric cams connected thereto to rotate synchronously, so that the box-type vibrator 7 drives the dehydration screen body 1 to vibrate through the mounting beam 71, and then the material can be put into the rear end of the sieve plate in the dehydration screen body 1, and the water above the overflow plate 8 directly flows out of the outside of the dehydration screen body 1. Under the action of the vibrating dehydration screen body 1, the material moves from the rear end of the sieve plate to the front end, and the material is dehydrated during the vibration process. Due to the different numbers of springs set in the front support and the rear support, the vibration amplitude of the material at different positions on the sieve plate is the same, thereby ensuring its dehydration efficiency. After dehydration, the material is directly output from the front end of the sieve plate to the unloading belt.
