Description

TECHNICAL FIELD

[0001] The utility model relates to a spiral machine technology field especially relates to a sealed spiral machine and system. BACKGROUND

[0002] The spiral dewatering machine (referred to as spiral machine) is a continuous dewatering equipment based on the screw extrusion principle, and its core working principle is that the rotation of the screw shaft pushes the sludge to move in the dynamic and static ring gap, and the continuous pressurization environment formed by the decreasing pitch is used to extrude water, so that solid-liquid separation is finally realized. Because of its high degree of automation, low energy consumption and no need to clean the filter cloth, the equipment gradually becomes the mainstream dewatering technology in the field of sewage treatment.

[0003] In the traditional (unsealed) or semi-sealed design spiral machine, due to the structural limitation, the following key problems exist:

[0004] 1. Sludge overflow and secondary pollution: when treating high-viscosity sludge or the instantaneous flow is too large, the sludge discharge capacity of the rear-end dewatering cavity (such as the back pressure plate area) is insufficient, resulting in sludge accumulation and even overflow. And in cleaning, the open spray cleaning system causes the waste water to increase by 200-300 tons / year, increasing the treatment cost.

[0005] 2. Environmental hazards and operation risks: harmful gases such as hydrogen sulfide and ammonia are easily diffused into the environment through the sludge guide plate or the impurity collection box, which also affects the operators. In addition, the unsealed feeding system is easy to mix in impurities such as fibers and sand, causing the dynamic and static ring gap to be stuck, and frequent shutdown for cleaning is required.

[0006] 3. Poor dewatering efficiency: the semi-sealed structure causes insufficient dewatering pressure, and the moisture content of the sludge cake is generally about 80%, which is lower than that of the plate and frame filter press (60%-70%).

[0007] Therefore, a new technical solution is needed to solve the above technical problems. UTILITY MODEL CONTENT
