Description

Technical Field

[0001] The utility model relates to the technical field of silos, in particular to an anti-blocking silo suitable for sludge. Background Art

[0002] Silos are a common type of storage equipment used to store and process bulk materials. They are widely used in agricultural feed production, powder industry, chemical industry, energy, metallurgy, packaging, food and pharmaceutical industries. Existing silos are mostly used for powder or granular materials with good fluidity. When storing high-viscosity and high-humidity sludge-like materials, due to the high viscosity between the sludge-like materials, they are easy to solidify and form lumps, or the sludge-like materials stick together and block the discharge port during the discharge process, greatly affecting production efficiency.

[0003] Therefore, there is an urgent need for an anti-blocking silo suitable for sludge. Summary of the Invention

[0004] The utility model aims to solve the problem that materials in existing silos are prone to agglomeration and clogging of the silo outlet when storing and discharging sludge. The utility model provides an anti-clogging silo suitable for sludge. After the sludge enters the silo, it is stirred by a stirring device to prevent the sludge from standing still and forming agglomerates; the stirred sludge naturally flows into the lower break-up device and leaves the silo through the break-up device to avoid clogging of the silo.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A silo for preventing sludge from blocking includes a silo supported on a bracket, and further includes a stirring device and a breaking device; the stirring device includes a stirring shaft rotatably arranged in the silo, multiple groups of stirring rods arranged on the stirring shaft, and a first driving part that drives the stirring shaft to rotate; the silo is used to store and transport sludge-like materials.

[0007] The dispersing device includes a plurality of blade assemblies, each of which is positioned at the material discharge port of the silo. The blade assemblies include at least one rotating blade assembly and at least two fixed blade assemblies. The rotating blade assembly is driven by a second drive unit and rotates relative to the silo. The fixed blade assembly is fixed to the inner side wall of the silo. The blade assemblies are arranged parallel to each other and staggered. The material is squeezed out of the silo through the gaps between the rotating blade assemblies. The dispersing device is used to disperse and squeeze the material in the silo to prevent the material from clogging the material discharge port.

[0008] Furthermore, the agitator shaft is provided with four sets of agitator rods along its circumference. Each set of agitator rods includes a plurality of parallel agitator rods arranged axially along the agitator shaft. Adjacent sets of agitator rods are staggered, and the angle between adjacent sets of agitator rods is 90 degrees. The agitator rods are used to agitate the material in the silo to prevent material agglomeration.

[0009] Furthermore, the stirring rod is L-shaped, and one end of the stirring rod is fixed on the stirring shaft.

[0010] Furthermore, the rotating blade assembly includes a plurality of rotating blades arranged in parallel, a rotating shaft passing through the center of the rotating blades, one end of the rotating shaft extending out of the material bin and connected to the second driving unit, and the outer edges of the rotating blades have a toothed surface. Adjacent sets of rotating blades squeeze each other to discharge material.

[0011] Furthermore, two rotating blade assemblies are arranged in parallel between the two fixed blade assemblies, and the rotation directions of the two rotating blade assemblies are opposite. The material leaves the silo from between the two rotating blade assemblies.

[0012] Furthermore, the fixed blade assembly includes a plurality of parallel fixed blades, each of which is arc-shaped on one side facing the rotating blade and is interspersed between the rotating blades of the rotating blade assembly. The fixed blades prevent material from getting stuck between the rotating blades and the silo wall and causing blockage.

[0013] Furthermore, the first drive unit and the second drive unit are both motors. The first drive unit and the second drive unit are power devices.

[0014] Furthermore, the upper portion of the silo is funnel-shaped, the lower portion is rectangular, the top of the silo is a feed inlet, and the bottom is a discharge port. Materials enter the silo from the feed inlet and leave the silo from the discharge port.

[0015] Furthermore, the bracket has a first platform and a second platform, the first platform is used to fix the first driving part, and the second platform is used to fix the second driving part.

[0016] Through the above technical solution, the beneficial effects of the utility model are:

[0017] The utility model provides a stirring device and a breaking device in the silo. The stirring device continuously stirs the sludge in the silo, thereby preventing the sludge material in the silo from forming large lumps due to being stationary. The fixed blade group and the rotating blade group in the breaking device work together to break up the lumps and discharge them or squeeze out the viscous sludge material from the blade gaps, thereby preventing the material from clogging the silo discharge port.

The blade assemblies are parallel to each other and staggered. The material is squeezed out from the gaps between the rotating blade assemblies and leaves the silo 1.

[0031] In this embodiment, two rotating blade groups 32 are arranged in parallel between the two fixed blade groups 33. The two rotating blade groups 32 rotate in opposite directions, bringing the materials on both sides of the silo 1 to the middle and leaving the silo 1 through the gap between the two rotating blade groups 32.
