A kind of vibrating screen of food granule sieve material
Technical field
The present invention relates to food granule screening installation field, specially a kind of vibrating screen of food granule sieve material.
Background technique
Food vibrating screen is a kind of equipment for food granule screening, can be to granulated sugar, salt, flavouring granules, beans
The food such as particle sell screening, to process, food vibrating screen set up for multilayer screening, have no dust overflow dissipate, work continuously,
The advantages that screening precision is high, high-efficient, small in size.
However, existing food vibrating screen is due to there is certain spacing between feed inlet and first layer sieve, in vibrating screen
During continuous work, sieve material is fallen directly into the centre of first layer sieve by feed inlet, can be persistently to the central part of sieve
Position carries out 90 degree of direct impact, so that the momentum that sieve bears sieve material vertical direction at this is larger, is easy to cause sieve
Position recess is screened in splicing, causes to sieve material heap product, so that the efficiency of screening reduces.
Summary of the invention
The present invention provides a kind of vibrating screens of food granule sieve material, have the high advantage of screening efficiency, solve background
The problem of being mentioned in technology.
The invention provides the following technical scheme: a kind of vibrating screen of food granule sieve material, including screen drum and cover on screen drum top
The cover in portion further includes the first layer mesh structure first layer mesh structure positioned at screen drum inner cavity, the first layer mesh structure
Including the fixed frame being fixedly mounted on inboard wall of riddle drum, supporting block, and supporting block and fixation are equipped at the center of the fixed frame
It is fixedly connected between the inside of frame there are four connecting rod, the connecting rod is equipped with first between fixed frame and supporting block
Sieve, the top of the supporting block inner cavity is equipped with tapered piece can shaken, and tapered piece of top surface is irregular male and fomale(M&F), institute
State cover top middle part be equipped with feed pipe, the bottom end of the feed pipe extend to the inside of screen drum and positioned at tapered piece just on
Side, and feed pipe and tapered piece of spacing are adjustable.
Preferably, screw thread is socketed with fixed block on the feed pipe, and feed pipe is located in screen drum and designs for bending-type, institute
It states and is fixedly connected at the top of the bottom and feed pipe of fixed block.
Preferably, the middle part on the supporting block top is equipped with elastic sponge, and the middle part of elastic sponge and tapered piece of bottom
Hold screw thread socket.
Preferably, described tapered piece it is outer diametrically greater than supporting block it is outer diametrically.
The present invention have it is following the utility model has the advantages that
The vibrating screen of food granule sieve material, by the setting of the middle part of the first sieve can micro- rolling tapered piece and feed pipe,
After sieve material is fallen on the tapered piece of irregular conical surface, so that the momentum direction of sieve material changes, sieve material will not be at the first sieve
90 degree directly contact, then cooperate tapered piece of buffering effect, substantially reduce the first sieve and bear the dynamic of sieve material vertical direction
Amount, so that the first sieve is not easy to be recessed, has ensured the normal use of sieve, has improved the efficiency of screening, and tapered piece of design can
Enable sieve material compared to existing equipment being distributed on the first sieve more evenly, further improve screening.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please referring to Fig. 1-3, a kind of vibrating screen of food granule sieve material including screen drum 1 and covers cover 2 at 1 top of screen drum,
It further include the first layer mesh structure first layer mesh structure 4 positioned at 1 inner cavity of screen drum, the first layer mesh structure 4 includes solid
Fixed frame 41 of the Dingan County on 1 inner wall of screen drum, fixed frame 41 can be secured by threads on the inner wall of screen drum 1, so as to the later period
Disassembly, supporting block 43 is equipped at the center of the fixed frame 41, the middle part on 43 top of supporting block is equipped with elastic sponge
431, and the middle part of elastic sponge 431 is socketed with tapered piece 45 of bottom end screw thread so that screen drum 1 is in vibration, tapered piece 45 with
Micro- vibration and shakes, tapered piece 45 of the irregular conical surface of cooperation so that the sieve material fallen on tapered piece 45 rebounds, position is different, into
And make on the first sieve 44 being distributed in around tapered piece 45 of sieve material more evenly, so that screening efficiency improves, and supporting block
It is fixedly connected between 43 and the inside of fixed frame 41 there are four connecting rod 42, the connecting rod 42, which is equipped with, is located at 41 He of fixed frame
The first sieve 44 between supporting block 43, the top of 43 inner cavity of supporting block are described tapered equipped with tapered piece 45 for can shaking
Block 45 it is outer diametrically greater than supporting block 43 it is outer diametrically, it is ensured that sieve material can fall on the first sieve 44 and be screened, and bore
The top surface of type block 45 is irregular male and fomale(M&F), and the middle part on 2 top of cover is equipped with feed pipe 3, the bottom end of the feed pipe 3
It extending to the inside of screen drum 1 and is located at tapered piece 45 of surface, screw thread is socketed with fixed block 31 on the feed pipe 3, and into
Expects pipe 3 is located in screen drum 1 to be designed for bending-type, is led to the friction of sieving materials and 3 inner wall of feed pipe, is reduced the kinetic energy of sieve material, into
And reduce the impact for shining material to the first sieve 44, and the effective service life for improving the first sieve 44, the bottom of the fixed block 31
Portion is fixedly connected with the top of feed pipe 3, the spacing that its bottom end Yu tapered piece 45 is adjusted by rotating feed pipe 3, thus right
The food granule of different quality is screened.
In use, sieve material is added by feed pipe 3, sieve material passes through curved feed pipe 3, reduces certain kinetic energy, and fall
On tapered piece 45 of the conical surface, tapered piece 45 is vibrated with screen drum 1, and rebound of the sieve material through tapered piece of 45 conical surfaces uniformly tiltedly falls on first
On sieve 44, the momentum that the first sieve 44 bears sieve material vertical direction is reduced, and the service life of the first sieve 44 is ensured, by the
One sieve 44 carries out primary dcreening operation.
