Description

A powder storage bin fluidizer that can be cleaned online

technical field

The invention relates to a powder or granule conveying device in the chemical, pharmaceutical and food industries, in particular to a bridge-breaking device that can be cleaned online.

Background technique

When powders or granules of different properties are temporarily stored or stored in the storage bin, wall hanging and bridging may occur. As an effective bridge-breaking device, the fluidizer is a flow-aiding component in the process of powder discharge from the warehouse. It is installed in the lower part of the hopper, please refer to the existing fluidizer schematic diagram shown in accompanying drawing 2. The compressed air enters the inner side of the bin body through the central hole of the air injection plug 1, pushes the fluidizer diaphragm 2 to open, and the air flow is ejected from the opening gap of the fluidizer diaphragm, and the surrounding materials are blown up to achieve the powder flow. state and unload smoothly, avoiding bridging problems. After the compressed air is disconnected, the diaphragm 2 of the fluidizer is tightly pressed against the inner wall of the hopper under the action of its own elasticity to prevent the material from entering the interior of the fluidizer. At present, the diaphragm fluidizer made of non-metallic material is widely used. Disadvantages of existing fluidizers:

a. The diaphragm of the fluidizer is easy to age and lose its elasticity, and cannot be sealed and the gap on the inner wall of the silo, resulting in material accumulation;

b. Installation and replacement are cumbersome;

Online washing and drying cannot be performed.

Contents of the invention

In order to solve the shortcomings of the aforementioned existing fluidizers, the present invention provides a powder storage bin fluidizer that can be cleaned online. The technical solution of the present invention is to fix an air valve on the storage bin wall, including a valve body And the valve core, the valve core is composed of the valve shaft and the valve core cap, the valve shaft is covered with a spring, one end of the valve body is filled with pressure gas, the valve core cap is affected by the pressure gas, and leaves the storage bin wall, at the same time, the pressure gas flows to the storage tank Spray in the silo to break up the agglomerated and bridging materials; remove the pressure gas, the spring makes the valve shaft shrink inward, and the valve core cap seals the jet nozzle of the valve body again.

One end of the valve shaft is connected to the valve core cap, and the other end is screwed to the screw through a washer. The right end of the screw has a plug screwed into the inner thread of the inner wall of the valve body, which closes the middle hole of the valve body so that compressed air cannot enter the spring area. . The right end of the valve body is screwed with an end cover, and the end cover is screwed with a gas pipe joint.

The valve body runs through several air holes from right to left, the air hole at the left end is sealed by the valve core cap, and the air hole at the right end communicates with the trachea joint.

The spring sleeved on the valve shaft has one end on the step of the through hole in the center of the valve body, and the other end on the washer. The valve core cap is affected by the pressure gas, which drives the valve shaft to move to the left in the valve body to remove the pressure gas. , the spring restoring force moves the valve shaft to the right

The invention has the advantages that the fluidizer can be cleaned online, the fluidizer has a long service life, and is safe and reliable. The material of the cap, the valve body and other internal parts of the present invention can be determined according to the specific material characteristics. Generally, it is required to be corrosion-resistant, wear-resistant, and high-temperature resistant. Its life can be very long, and it can meet the online cleaning, drying, Sterilization requirements.

Detailed ways

Please refer to shown in accompanying drawing 1, the present invention is to fix an air valve on storage bin wall 3, comprises valve body 6 and valve core, and valve core is made of valve shaft 14 and valve core cap 1, and valve shaft 14 is covered with spring 7. One end of the valve body 6 is filled with pressure gas, and the valve core cap 1 is affected by the pressure gas and leaves the storage bin wall 3. At the same time, the pressure gas is sprayed into the storage bin to break up the agglomerated and bridging materials; remove the pressure Gas, the spring 7 makes the valve shaft 14 shrink inwardly, and the valve core cap 1 covers the jet nozzle of the valve body again.

One end of the valve shaft 14 is connected to the valve core cap 1, and the other end is screwed to the screw 9 through a washer 8. The right end of the screw 9 has a plug 10 screwed on the internal thread of the inner wall of the valve body 6, and the right end of the valve body 6 is connected with an end cap. 12 are screwed, and the end cap 12 is screwed with a trachea joint 13.

The valve body 6 runs through several vent holes 15 from right to left, the vent hole at the left end is covered by the valve core cap 1 , and the vent hole at the right end communicates with the trachea joint 13 .

The spring 7 sleeved on the valve shaft has one end on the step of the through hole 16 in the center of the valve body 6, and the other end on the gasket 8. The valve core cap 1 is affected by the pressure gas, driving the valve shaft 14 on the valve body 6. Move to the left, remove the pressure gas, the spring restoring force makes the valve shaft 14 move to the right

The mounting base 4 is welded on the outer wall 3 of the storage bin. The valve body 6 is screwed on the mounting seat 4 . The nut 5 tightens the valve body 6 so that it does not loosen.
