Description

Technical field:

[0001] The utility model relates to the technical field of dewatering screens, in particular to an improved vibration dewatering screen structure. Background technology:

[0002] Dewatering screen is mainly used in coal preparation plants and ore dressing plants for pre-dewatering, desliming, de-mediuming and graded coal slime recovery. It can also be used in conjunction with water cyclone to effectively grade, dewater, deslim and de-medium fine-grained materials. Dewatering screen is mainly composed of screen box, curved screen surface, vibrating base, vibrating motor and other components. In actual use, the technical problem of dewatering screen is that the resistance of dewatered coal slime increases and it is easy to accumulate at the end of the curved screen surface, resulting in slow material dropping speed and even blockage, which affects the working efficiency of dewatering screen. Secondly, all the weight of dewatering screen is concentrated on the vibrating base, which bears too much load. When the boring on the screen surface is uneven, the vibrating base bears huge shear force, which makes the vibrating base easy to be damaged and needs to be improved urgently.

[0006] Furthermore, a material hole is opened on the material box, and the material hole is slidably connected to the discharge pipe. A second compression spring is sleeved on the discharge pipe, and the second compression spring is located between the material box and the screen body.

[0007] Furthermore, the residual mud blowing assembly comprises an air pipe installed on the outer wall of the sieve body, and a plurality of air nozzles are installed on the air pipe, and the air nozzles blow the screen surface of the sieve plate.

[0008] Furthermore, there is a clearance fit between the pull rod and the sliding hole, and between the material hole and the discharge pipe.

[0009] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and changes the traditional load-bearing mode of the vibration machine base into a structure of comprehensive load-bearing of elastic lifting load-bearing and bottom drop pipe, which has better load-bearing performance and significantly reduces the equipment failure rate; at the same time, a residual mud purge assembly is designed at the end of the screen plate where coal slime is easily accumulated to reduce the friction of the coal slime and ensure the normal drop of the coal slime, which is worthy of large-scale promotion and use.
