Hydraulic control hopper

Abstract

The invention relates to a hydraulic control hopper installed below solid producing equipment. The hydraulic control hopper comprises a hydraulic control hopper body, suspension supporting legs and suspension lugs, wherein a cutting screen is installed in an upper opening in the hydraulic control hopper body, a material level switch is arranged below the cutting screen, an arc opening and closing hopper is installed on the outer wall of a lower opening of the hydraulic control hopper body, two collision stroke switches and two hydraulic push rods are arranged on the side wall of the hydraulic control hopper body, and an anti-seepage pressing strip is arranged at the end face of the lower opening of the hydraulic control hopper body. The hydraulic control hopper has the beneficial effects that the cutting screen is used for cutting large solid-phase objects into pieces, and the solid-phase object pieces obtained after cutting are distributed more evenly in the hopper; the opening and closing hopper is of an arc structure, so that the stress structure is more reasonable, space occupied during rotation is small, and the opening or closing resistance is reduced through full contact of the anti-seepage pressing strip; the pushing mode with the dual hydraulic push rods is adopted, the dual hydraulic push rods operate simultaneously for pushing, and thrust balance is achieved; by adoption of the collision stroke switches, the opening or closing position is controllable; and the material level switch can test the height of the solid-phase objects and give out a full level alarm, and thus the hopper can be in an automatic monitoring state.

Description

technical field [0001] The invention relates to a liquid control hopper. Background technique [0002] The liquid control hopper is a solid-phase material storage device that is often used in water treatment systems or solid-phase treatment systems, such as sludge storage in dewatering systems, solid-phase material storage equipment for lime slag, ash, etc. Due to some specific use occasions, according to the characteristics of the operating process, the formation process of solid-phase substances is often produced continuously and continuously, so it cannot be completed at one time. Considering the needs of the environment, it is necessary to set up an intermediate storage device to collect such solid-phase substances . For example, in the water treatment system, when the desliming system is in operation, the sludge dewatering machine is in continuous operation, the mud and water are continuously separated, and the solid phase sludge is continuously generated during the op...

Problems solved by technology

[0003] There are many kinds of conventional solid-phase material storage equipment, such as screw conveying equipment, knife gate valve solid bucket, etc., screw conveying equipment, through screw push, the generated materials are transported from one place to another, which can realize the transfer of materials, but cannot realize Storage function, and it occupies a large area, needs enough space to realize, so there are certain limitations in use; and the solid bucket of the knife gate valve, in the process of storing solid substances, due to the simple structure of the equipment, there is gravity in the process of solid substances entering. Under pressure conditions, the requirements for the valve plate of the knife gate valve are relatively high, it is easy to be smashed and deformed, and there is a great hidden danger to the free opening of the gate plate.
