Deeply-dehydrated sludge homogenizing discharge device for sewage plant plate-frame machines

Abstract

The invention discloses a deeply-dehydrated sludge homogenizing discharge device for sewage plant plate-frame machines. Hopper walls distributed on the inner side obliquely are formed on two sides of the lower end a feeding hopper, a discharge opening is formed between the lower ends of the hopper walls on two sides, an opening and closing valve is arranged at the discharge opening and composed of a left valve plate and a right valve plate in symmetrical distribution, a group of cross stirring rollers is arranged in the feeding hopper and above the discharge opening, a chute feeding mechanism is arranged below the discharge opening, a front chute and a rear chute are formed on the outer sides of the two sides of the chute feeding mechanism obliquely, a vertical chute is formed the middle of the chute feeding mechanism downwardly, a distribution guide plate is arranged over the vertical chute, a rotating shaft is arranged at the valve plate center of the distribution guide plate, and the valve plates rotate by taking the rotating shaft as a center pivot. By the homogenizing discharge device, falling is uniform during sludge discharge; compared with the existing discharging technique, the homogenizing discharge device has the advantages that transport capacity of transporting cars is increased by more than 90%, sludge clods fall on the ground rarely during discharging, and manpower and human resources are saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a deep dewatered sludge homogeneous unloading device for a plate and frame machine in a sewage plant, and in particular to its mechanical connection structure. Background technique [0002] In the sewage purification project of the sewage treatment plant, a large amount of sludge is produced every day. The sludge is dehydrated by the plate and frame filter press until the moisture content is below 60%. The sludge after the plate and frame filter is sent to into the sludge hopper, the driver parks the transport vehicle under the loading hopper, opens the hopper door, and unloads the mud in the hopper into the transport vehicle. During the loading process, the driver visually observes the loading conditions, When it is found that the mud clods are partially accumulated on the trunk board and higher than the trunk board, the car must be moved forward to make the mud clods ...

AI Technical Summary

Problems solved by technology

As a result, the loading of the box is unbalanced, some parts are unloaded too much and overflow the car box, and some parts are not loaded enough to waste transport capacity.

The mud clods overflowing the carriages are scattered on the ground, and manpower must be used to collect and wash the scene, wasting a lot of manpower and material resources
