Description

Bamboo powder feed arrangement

Technical Field

The utility model relates to a bamboo article processing equipment technical field, in particular to bamboo powder feed arrangement.

Background

The bamboo product processing can generate a large amount of bamboo powder, the bamboo powder can be recycled to be made into bamboo boards and other articles, the bamboo powder needs to be mixed with other materials before being processed into finished products and then extruded and molded, and therefore the powder needs to be put into mixing equipment through a feeding bin before being mixed, but the defect of the structure of the current feeding bin 1 is that the powder is thin, and negative pressure is easy to occur in the middle of the powder in the feeding bin in the powder feeding process, so that the powder is not smooth to feed; 2. and the material is pressed into the block structure easily by gravity extrusion when storing, and the import of infundibulate feeder hopper is big, export little reason for the block material forms the jam in material mouth department easily, and then influences the transmission of material.

Like the bamboo wood powder feeding storehouse of publication number cn205574708u, it obviously divides into two less feeder hoppers with big feeder hopper in the past, but this can not change the fact that two parts feeder hopper all belong to two independent individualities, so because every part feeder hopper all belongs to an independent feeder hopper (volume reduces only), so still can have its problem of mentioning, can know clearly according to its drawing simultaneously that the material that falls to on the feed bin from last feed bin bottom opening is obviously greater than the material flow that the small-size feed bin bottom was discharged, so the material in the feed bin can certainly spill from the opening that constitutes between baffle and the last feed bin.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples with reference to fig. 1-2.

The utility model provides a bamboo powder feed arrangement, including installing hopper 3 that leaks hopper-shaped at mixing arrangement feed inlet 1 department, as shown in fig. 1, 2, this hopper 3 is including outer fill 31 and interior fill 32, wherein the minimum open end of outer fill 31 is located feed inlet 1, and interior fill 32 bottom is higher than outer fill 31 bottom horizontal plane, the welding has the round to hug closely the support limit 11 on mixing arrangement top casing 2 on the outer lateral wall of outer fill 31 simultaneously, and install locking bolt 12 of locking it on mixing arrangement top casing 2 on the support limit 11, with this prevent that outer fill 31 from taking place the displacement condition on feed inlet 1 and mixing arrangement.

And evenly weld between internal bucket 32 lateral wall and the 31 inside walls of outer fill has many spinal branchs braces 4, wherein brace 4 can be unsettled fix in outer fill 31 with internal bucket 32 and can not take place the displacement condition, and all be constructed air circulation passageway 5 between two adjacent brace 4 and internal bucket 32 lateral wall and the 31 inside walls of outer fill, when throwing the material, with the leading-in internal bucket 32 of powder, then drop into outer fill 31 in through internal bucket 32 export, at last again from the 31 export of outer fill entering mixing apparatus in, because be constructed air circulation passageway 4 between external bucket 31 and the internal bucket 32, make multiunit air circulation passageway 4 can play certain ventilation decompression's effect in to feeder hopper 3, consequently make the unloading in the feeder hopper 3 ordinary, reduce the probability that takes place feeder hopper 3 blocking phenomenon.

Wherein in order to prevent that the material can directly get into it inside from 4 top openings of circulation of air passageway when reinforced in the inside fill 32, the inside fill 32 top extends to the outer fill 31 outside in this embodiment, and the inside fill 32 top still turns over outwards to have the hem 6 of sheltering from circulation of air passageway 4, this hem 6 shelters from 4 top openings of circulation of air passageway, in order to prevent the material that directly falls to fall into circulation of air passageway 4, be equipped with last ventilative mouthful 14 that communicates circulation of air passageway 4 between 6 bottoms of hem and the outer fill 31 top simultaneously, this last ventilative mouthful 14 can make circulation of air passageway 4 and exterior space intercommunication, make carry out the circulation of air between exterior space and the circulation of air passageway 4.

And interior fill 32 bottom is rolled over outward and is rolled over and has arc hunch-up portion 7, and it has the lower ventilative mouth 15 of intercommunication circulation of air passageway 4 to construct between 7 tops of hunch-up portion and the 31 inside wall of outer fill, wherein lower ventilative mouth 15 enables circulation of air passageway 4 and the interior lower half intercommunication of outer fill 31, make and carry out circulation of air between the lower half in the outer fill 31 and the circulation of air passageway 4, reduce the opening degree of circulation of air passageway 4 bottom through hunch-up portion 7 simultaneously, and it can also block the material that falls from interior fill 32 to a certain extent, make the material be difficult for getting into in the circulation of air passageway 4.

Meanwhile, a rack 8 is horizontally installed right above the feed hopper 3, four groups of top corners at the bottom of the rack 8 are respectively welded with I-beams 9 positioned outside the feed hopper 3, as shown in fig. 1, fixing bolts 13 for locking the I-beams 9 on the mixing equipment shell 2 are arranged at the bottom of the I-beams 9, and the rack 8 is indirectly fixed on the shell 2 in a hanging manner in a mode that the I-beams 9 are locked on the shell 2 through the fixing bolts 13.

As a preferable scheme, since a small amount of the materials are in a caking state, so that the feed hopper 3 is easily blocked by the massive materials, or the mixing effect is not good when the massive materials enter the mixing device, in this embodiment, the stirring mechanism 10 is installed on the top of the frame 8, wherein the stirring mechanism 10 includes a motor 101 installed on the top of the frame 8, a rotating shaft 102 of the motor 101 penetrates through the frame 8 and sequentially passes through the circle centers of the inner hopper 32 and the outer hopper 31, wherein the bottom end of the rotating shaft 102 extends into the mixing device, and the distance between the bottom end of the rotating shaft 102 and the bottom wall of the housing 2 is not more than 1-2 cm, so as to prevent the rotating shaft 102 and the helical stirring paddle 103 from interfering with the normal operation in the mixing device, and the helical stirring paddle 103 is further arranged on the rotating shaft 102 located in the inner hopper 32, the outer hopper 31 and the stirring device 10, so, thereby will follow and fight 32 and outer the material that falls down and carry out the breakage in fighting, and the material after the breakage falls into the mixing apparatus and carries out processing on next step to this realizes carrying out the breakage to the caking material and prevents that cubic material from blockking up the purpose of feeder hopper 3, and carry out artificial intervention through rabbling mechanism 10 with the material in the feeder hopper 3 and force leading-in mixing apparatus with it in, in order to accelerate feeding efficiency and effect.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
