Problems solved by technology

However, for this kind of storage device, firstly, because the vibrator is arranged outside the storage device, it is difficult to break the sludge; secondly, the vibrator can only vibrate the discharged sludge during the discharge process, and the Still cannot avoid the formation of arches during storage
[0007] In addition, for the scheme of manual arch breaking, since the sludge storage device is usually large and the working environment is poor, manual arch breaking is difficult and time-consuming, so it is often inefficient

Embodiment Construction

[0062] The following description is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0063] Such as figure 1 As shown, according to an example of the present invention, the storage device 1 has an inner space defined by a casing, and the casing includes an upper cover 202 and a main body 203 . The upper cover of the storage device is provided with at least one feed port 4 for transporting the dried sludge into the storage device, and at least one discharge port 5 is provided at the bottom of the housing for the The dried sludge is discharged from the storage device. exist figure 1 Only one feed opening 4 and one discharge opening 5 are shown in . It should be understood that the housing may comprise multiple feed ports 4 and / or multiple discharge ports 5 without going beyond the scope of the present invention. In another embodiment, the main body may further include a side wall and a bottom plate, and the feed inlet m...

Abstract

The invention relates to a material storage device, which comprises: a shell, wherein the shell is provided with at least one feed port for conveying to-be-stored sludge into the material storage device, at least one exhaust port and at least one discharge port for discharging the sludge; and at least one ventilation assembly configured to convey a dry gas medium into the material storage device,wherein the at least one ventilation assembly is provided with at least one turning sub-assembly, and the turning sub-assembly is configured to turn sludge in the material storage device, so that thesludge in the material storage device is prevented from caking and being attached to the inner surface of the side wall of the shell.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, more specifically, the invention relates to a material storage device and an operation method. Background technique [0002] With the rapid economic development, the amount of urban domestic sewage is increasing day by day. In order to meet the treatment needs of urban sewage, my country has accelerated the expansion of sewage treatment plants, so that sewage has been effectively controlled. At present, sewage treatment plants usually use the method of concentrating and tempering and then mechanically dehydrating the sludge to treat the sludge. The sewage is dehydrated to a moisture content below about 60%, and then it is collected in corresponding storage bins for temporary storage. The treated sludge is subsequently landfilled and solidified. Due to the high moisture content of the dewatered sludge, it is easy to ferment in the storage bin to form an arch layer or arch. [0003] In ...
