Abstract

The utility model discloses a sieve bend blanking memory device, it is including the buffer memory hopper, and the feed inlet setting of buffer memory hopper is equipped with vibrating motor in the discharge gate below of sieve bend on the outer wall of buffer memory hopper, and the bottom of buffer memory hopper is equipped with the discharging pipe, and the pan feeding mouth pipeline connection of gate valve and centrifuge is passed through in the export of discharging pipe. The utility model has the advantages that: coarse and fine particle coal slime products after being dehydrated and de-sized by the sieve bend are buffered by the buffer hopper, and the coal falling amount of the buffer hopper is controlled by the opening degree of the adjusting gate valve on the discharging pipe, so that the materials are continuously and uniformly fed to the centrifuge, the stability and continuity of subsequent production are ensured, the problems of intermittent feeding from the sieve bend to the centrifuge and influence on the stable operation of the centrifuge are solved, and the treatment efficiency of the centrifuge on coal is improved.

Description

Blanking buffer memory device for sieve bend

The technical field is as follows:

the utility model relates to a coal washing selects technical field, concretely relates to sieve bend blanking buffer memory device.

Background art:

in coal production, according to the characteristics of fine coal slime, a classification cyclone is often used for mineral separation and classification of the coal slime, and classified coal is subjected to primary dehydration through a sieve bend and then enters a centrifuge for secondary dehydration to form coarse clean coal. Due to the influences of the problems of blockage of the sieve screen of the sieve bend, installation angle of the sieve plate, physical properties of materials, vibration frequency of the sieve bend and the like, the coal discharged after medium removal and dehydration of the sieve bend is unstable and discharged intermittently, so that the coal is fed intermittently into the centrifugal machine, the requirements of the centrifugal machine on design and use conditions are not met, the service life of the centrifugal machine and subsequent normal production are influenced, and the working efficiency is reduced.

The utility model has the following contents:

an object of the utility model is to provide a through the even blanking of sieve bend dehydration back coal, guarantee the sieve bend blanking memory device that follow-up production normally goes on.

The utility model discloses by following technical scheme implement: sieve blanking buffer memory device, it is including the buffer memory hopper, the feed inlet setting of buffer memory hopper is in the discharge gate below of sieve bend, the bottom of buffer memory hopper is equipped with the discharging pipe, the export of discharging pipe is passed through the gate valve and is connected with centrifuge's feed pipeline.

Furthermore, a vibration motor is arranged on the outer wall of the buffer hopper.

The utility model has the advantages that: coal screened by the sieve bend firstly passes through the buffer of the buffer hopper, the coal falling amount of the buffer hopper is controlled by adjusting the opening degree of the gate valve, the discharge of the sieve bend is continuously and uniformly fed to the centrifuge after being distributed again through the buffer hopper, the efficient production of subsequent production equipment and processes is ensured, and the treatment efficiency of the centrifuge on the coal is improved.

Description of the drawings:

in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural view of the present invention.

In the figure: the buffer hopper 1, the sieve bend 2, vibrating motor 3, discharging pipe 4, slide valve 5, centrifuge 6.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, sieve bend blanking memory device, it is including buffer memory hopper 1, the feed inlet setting of buffer memory hopper 1 is in the discharge gate below of sieve bend 2, buffer memory hopper 1 can carry out the buffer memory to 2 sieve back exhaust coals, guarantee the even blanking of coal in the buffer memory hopper 1, be equipped with vibrating motor 3 on the outer wall of buffer memory hopper 1, promote the at the uniform velocity blanking of coal in the buffer memory hopper 1 after vibrating motor 3 starts, prevent that coal from causing the jam in buffer memory hopper 1, the bottom of buffer memory hopper 1 is equipped with discharging pipe 4, the export of discharging pipe 4 is passed through slide valve 5 and centrifuge 6's entry pipeline and is connected, slide valve 5 is used for adjusting the coal breakage volume that gets into centrifuge 6.

The specific operation process of the embodiment is as follows:

coal after the sieve bend 2 sieves gets into in the buffer storage hopper 1, starts vibrating motor 3, through the blanking volume of coal in the gate valve 5 control buffer storage hopper 1, guarantees that centrifuge 6's feeding is even stable.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
