Description
Technical Field
The utility model relates to a centrifuge field, especially a centrifuge arranges cinder notch structure.
Background
Centrifuges are machines that utilize centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. Centrifuges have a cylinder, called a bowl, which rotates at high speed about its own axis, usually driven by an electric motor. After the separated material enters the rotary drum, the separated material is rapidly driven to rotate at the same speed as the rotary drum, and the components are separated and discharged respectively under the action of centrifugal force. Generally, the higher the drum speed, the better the separation. The centrifugal machine is widely applied to chemical, petroleum, food, pharmacy, ore dressing, coal, water treatment, ships and other departments.
The horizontal screw centrifuge is a settling equipment with horizontal screw discharging and continuous operation. The working principle of the centrifuge is that the drum and the screw rotate at a high speed in the same direction at a certain differential speed, materials are continuously introduced into the inner cylinder of the material conveying screw through the material inlet pipe, enter the drum after being accelerated, and under the action of a centrifugal force field, heavier solid substances are deposited on the wall of the drum to form a slag layer. The conveying screw continuously pushes the deposited solid-phase substances to the conical end of the rotary drum and discharges the solid-phase substances out of the machine through the slag discharge port. The lighter liquid phase forms an inner layer liquid ring, continuously overflows from the rotary drum through an overflow port at the large end of the rotary drum, and is discharged out of the machine through a liquid discharge port. The horizontal screw centrifuge is widely used in the industries of chemical industry, light industry, pharmacy, food, environmental protection and the like.
The solid slag discharge port of the horizontal screw centrifuge is usually designed on a conical section rotary drum, n slag discharge holes ((n >2 and n is a natural number) with the diameter d are uniformly distributed along the radial direction of a rotation center, as shown in the attached drawing of the specification and figure 3, when a screw pushes solid slag to the position of a slag discharge channel hole, the solid slag can be discharged out of the rotary drum along the slag discharge channel hole under the action of centrifugal force, but a slag discharge dead angle is formed between two slag discharge channel holes, the slag cannot be discharged in the region, only when the screw pushes the solid slag to the position of the next slag discharge channel hole, the solid slag can be discharged along the slag discharge channel hole, because the slag is continuously pushed along a helical blade channel, the slag is broken and continuous when passing through the slag discharge hole, when the amount of the slag conveyed by the screw is greater than the slag discharge capacity of the slag discharge channel hole, the slag can be accumulated at the position of the slag discharge channel hole, blocking is easily formed, and the slag discharge torque of a, causing torque overload shutdown and even damage to the differential. In order to improve the slag discharging capacity of the slag discharging channel holes, the purpose can be achieved by increasing the diameter of the slag discharging channel holes and the number of the slag discharging channel holes, but the improvement of the diameter of the slag discharging channel holes and the number of the slag discharging channel holes is limited by the strength of the rotary drum and cannot be infinitely improved. The slag discharge capacity of the horizontal screw centrifuge is determined only by the smaller of the slag discharge capacity of the screw blade and the slag discharge capacity of the slag discharge passage hole. Therefore, the improvement of the slag discharge capacity of the slag discharge channel hole has great significance for improving the slag discharge capacity of the horizontal screw centrifuge.
SUMMERY OF THE UTILITY MODEL
