Description

Technical Field

[0001] This utility model relates to the field of sludge composting technology, and in particular to a sludge buffer silo with an impurity separation structure. Background Technology

[0002] Sludge composting is essentially a form of waste stabilization, but it requires specific humidity and ventilation conditions to generate a suitable temperature, generally considered to be above 45°C. Maintaining this high temperature can inactivate pathogens and kill weed seeds. After proper composting, the residual organic matter has a low decomposition rate and is relatively stable. The odor of the compost can be greatly reduced, and composting can also produce a significant drying effect. This is very useful for treating moist materials such as municipal and industrial sludge. Sludge composting often requires the use of buffer silos.

[0003] The existing sludge buffer silos have a design flaw: they are not equipped with impurity interception and separation structures. This drawback allows large particles of impurities mixed in with the sludge to enter the buffer silos without hindrance, which in turn has an adverse effect on the overall quality of the sludge in the silos. Utility Model Content

[0004] This utility model relates to a sludge buffer silo with an impurity separation structure, which solves the problem that existing sludge buffer silos lack an internal structure for intercepting and separating impurities, causing large particles of impurities mixed in with the sludge to enter the buffer silo and affect the quality of the sludge inside the buffer silo.

[0005] In a first aspect, this utility model provides a sludge buffer silo with an impurity separation structure, specifically comprising: a silo and a filter; the silo has an inlet at its top and a outlet at its bottom; the filter is mounted on the top of the silo, and the filter consists of an outer shell, a top cover, a filter cartridge, a motor, a rotating frame, a movable sleeve, and a spring; the bottom of the outer shell is connected to the top of the silo, and the top of the outer shell is connected to the top cover, with the filter cartridge located inside the outer shell; the motor is fixedly mounted on the top of the top cover, and the motor's drive shaft is connected to the rotating frame, which is located inside the outer shell and surrounds the filter cartridge; the movable sleeve is slidably connected to the outside of the outer shell and is connected to the top cover.

[0006] Furthermore, the outer shell is provided with a mud inlet, the bottom of the outer shell is provided with a mud outlet, the mud outlet is connected to the feed inlet, the filter cylinder is provided with a filter screen, the inside of the filter cylinder is connected to the mud outlet, and the outside of the filter cylinder is connected to the mud inlet.

[0007] Furthermore, a positioning groove is provided at the top of the sludge discharge port, and a positioning block is provided at the bottom of the filter cylinder. The positioning block is inserted into the positioning groove, and the top of the filter cylinder is in contact with the rotating frame.

[0008] Furthermore, the rotating frame is rotatably connected to the filter cylinder, and metal brush filaments are provided on the inner side of the rotating frame, which are in contact with the filter screen.

[0009] Furthermore, an L-shaped slot is provided around the top of the outer shell, and a locking block is provided on the outside of the top cover, which is connected to the L-shaped slot.

[0010] Furthermore, a guide block is provided on the outside of the outer shell, and a sliding hole is provided inside the movable sleeve. The guide block is slidably connected in the sliding hole, and a locking groove is provided on the top of the movable sleeve. When the locking block is located at the innermost end of the L-shaped locking groove, the locking block is connected in the locking groove.

[0011] Furthermore, the spring is fitted outside the outer casing, with the bottom of the spring in contact with the outer casing and the top of the spring in contact with the bottom of the movable sleeve.

[0012] This utility model provides a sludge buffer silo with an impurity separation structure, which has the following beneficial effects:

[0013] In use, after the sludge enters the filter, large particles of impurities are intercepted by the filter screen, preventing them from entering the filter. The filtered sludge is then discharged into the silo, effectively ensuring the quality of the sludge inside the silo. The positioning block and positioning groove are interlocked to limit and fix the filter cartridge, preventing it from rotating. The motor drives the rotating frame to rotate at a constant speed, and the metal brushes clean the impurities attached to the outside of the filter screen, preventing the impurities from clogging the filter screen openings and affecting the flowability of the sludge.

[0014] Furthermore, the top cover is connected to the top of the outer shell by a rotating snap-fit ​​mechanism, making it easier to assemble and disassemble. After the top cover is connected to the top of the outer shell, the locking block moves to the innermost end of the L-shaped slot, and the movable sleeve moves upward under the influence of the thrust, so that the locking block is located in the locking groove, locking and fixing the top cover. When it is necessary to clean the impurities intercepted by the filter screen regularly, the movable sleeve is moved downward, the spring stores and contracts, the locking block separates from the locking groove, the top cover is unlocked, and the top cover can be rotated in the opposite direction to separate the top cover from the top of the outer shell, and the filter cartridge can be taken out of the outer shell to clean the impurities accumulated inside the outer shell. The operation is more convenient.
