Abstract

The invention relates to a screening device, in particular to a granulation screen buffer device. The granulation screen buffer device comprises a shell, a feeding hopper and a screen, wherein the feeding hopper is located at the upper end of the shell and connected with the shell, and the screen is located in the shell. The granulation screen buffer device is characterized in that a buffer device body is further arranged in the feeding hopper, the buffer device body comprises a baffle, a fixed shaft and a support used for fixing the fixed shaft, the support is arranged between the fixed shaft and the feeding hopper, the fixed shaft is vertically arranged inside the feeding hopper, the baffle is transversely arranged at one end of the fixed shaft and rotatably connected with the fixed shaft, and a discharging port is formed in the baffle or a gap used for discharging is formed between the baffle and the feeding hopper. The granulation screen buffer device has the advantages that through the arrangement of the buffer device body, the impact force on the screen by fodder granules is effectively reduced, and the service life of the screen is prolonged.

Description

The buffer unit of granulation screen cloth
Technical field
The present invention relates to a kind of screening plant, be specially a kind of buffer unit of screen cloth of granulating.
Background technology
along with the development of China's aquaculture, market is also increasing for the demand of feed.After feed granules produced by granulator, need the screening through screening plant could obtain the comparatively uniform finished particle of particle diameter.Owing to being subject to the restriction of existing equipment and factory floor space; granulator is often arranged on lower floor; screening plant is arranged on upper strata; after feed granules is made; be transported to the top of screening plant by the conveyance conduit of lifting means, then feed granules utilizes the gravitional force of self to be slipped on the screen cloth of screening plant from pipeline.The velocity ratio fallen due to feed granulating is very fast, and is again that continuous print falls, so can produce larger impulsive force to screen cloth, thus screen cloth is worn very soon, causes to shut down and repair, reduce production efficiency.
Summary of the invention
The object of this invention is to provide a kind of buffer unit of screen cloth of granulating, solve the problem that in feed preparation, screen cloth is worn soon.
To achieve these goals, the buffer unit of a kind of screen cloth of granulating provided by the invention, comprises housing, feed hopper, screen cloth; This feed hopper is positioned at housing upper end and is attached thereto, this screen cloth is positioned at housing, it is characterized in that: in described feed hopper, be also provided with buffer unit, described buffer unit comprises baffle plate, fixed axis and for fixing fixing shaft support, this Bracket setting is between fixed axis and feed hopper, this fixed axis is vertically arranged at feed hopper inside, this baffle plate is horizontally set at one end of fixed axis and is rotationally connected with fixed axis, and this baffle plate is provided with blanking port or is provided with the gap of blanking between baffle plate and feed hopper.The buffer unit of granulation screen cloth
Compared with prior art, the advantage of this programme is: because the support static connection of this buffer unit is on hopper, fixed axis static connection is on support, flapper is connected on fixed axis, when feed granules enters screening plant from eminence landing, first be that oblique impact is to baffle plate upper surface, and produce phase mutual friction with baffle plate upper surface, reduce the speed of feed granules, the feed granules simultaneously constantly fallen produces the shock continued to baffle plate, drive the baffle plate be rotationally connected with fixed axis, thus feed granules is moved in a circle along baffle plate, feed granules is made to disperse to enter screen cloth, thus the impulsive force reduced screen cloth.
As preferred scheme, conically, the upper surface of this baffle plate is provided with the raised line radially distributed to the shape of baffle plate.Be conducive to increasing the frictional force between feed granules and baffle plate.
As preferred scheme, the tapering of baffle plate is 10 ︰ 1.Be conducive to feed granules not pile up on baffle plate.
As preferred scheme, support is made up of brace and horizon bar, and the shape of this support is rectangular pyramid shape, and this horizon bar is arranged along the diagonal of frame bottom.Be conducive to support and form an entirety, stability is better.
As preferred scheme, baffle plate is connected with fixed axis by bearing.Be conducive to reducing the frictional force between baffle plate and fixed axis.
Accompanying drawing explanation
Fig. 1 is that the present invention granulates the structural representation of buffer unit of screen cloth;
Fig. 2 is that the present invention granulates the top view of buffer unit of screen cloth.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
In figure: baffle plate 1, fixed axis 2, feed hopper 3, brace 4, nut 5, horizon bar 6, raised line 7, screen cloth 8
As shown in Figure 1, a kind of buffer unit of screen cloth of granulating, comprise feed hopper 3, screen cloth 8 and buffer unit, buffer unit comprises circular baffle plate 1, raised line 7, fixed axis 2, brace 4, horizon bar 6 and nut 5, the bottom centre of baffle plate 1 is provided with stair-stepping through hole, be provided with a bearing in through hole, bearing is connected with through hole interference fit.Meanwhile, fixed axis 2 passes bearing inner race and is connected with bearing interference fit.Upper surface radial uniform welding centered by through hole of baffle plate 1 has ten six roots of sensation raised lines 7.The part that fixed axis 2 passes bearing is provided with screw thread and is connected with a nut matched 5.Fixed axis 2 is vertically arranged at the center of feed hopper 3, and the lower end of fixed axis 2 is welded with horizon bar 6, and one end that its near middle is higher with brace 4 is welded.One end that brace 4 is lower is welded with one end of contiguous feed hopper 3 inwall of horizon bar 6, and the two ends of horizon bar 6 are welded with the inwall of feed hopper 3, the contiguous screen cloth 8 in bottom of feed hopper 3.
When using the buffer unit of this granulation screen cloth, first the feed granules with greater impact power fallen drops on baffle plate 1, and produce larger frictional force with baffle plate 1, baffle plate 1 is rotated under the effect of frictional force, thus feed granules is fallen from the edge dispersion of baffle plate 1, the speed of feed granules has also been lowered simultaneously.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
