Abstract
The utility model discloses a roll-in mill feed arrangement in roll-in equipment field, including setting up the batcher in crude product feed bin export and the weighing scale feeding weighing hopper that is located the batcher exit, the bottom export of weighing scale feeding weighing hopper links to each other with the feed inlet that the roll-in mill was ground, the weighing scale feeding weighing hopper's the volume of weighing correlates with the feed speed of batcher the beneficial effects of the utility model are that through setting up batcher and weighing scale feeding weighing hopper between crude product feed bin and roll-in mill, the feed speed of batcher is adjusted according to the volume of weighing scale feeding weighing hopper, makes material steady quality in the weighing scale feeding weighing hopper to guarantee that roll-in mill feeds evenly, stable, prolonged compression roller mill life, improved system production efficiency, reduced roll-in mill fault rate, whole system stability improves.
Description
Technical Field
The utility model relates to a roll-in equipment field especially relates to kind of roll-in mill feed arrangement.
Background
In the production process of titanium dioxide by a sulfuric acid method, the calcined crude titanium dioxide is subjected to intermediate crushing treatment to ensure that the fineness of the crude titanium dioxide reaches fixed requirements, and the roller mill is energy-saving grinding devices, has low energy consumption, low noise and high efficiency, and is widely applied to an intermediate crushing process of titanium dioxide by the sulfuric acid method by .
In the crushing system of the rolling mill, the material segregation in the feeding hopper above the rolling mill often occurs, so that the feeding of the rolling mill is uneven, the gap of the rolling mill is uneven, the efficiency of the rolling mill is seriously affected, even the fault of the rolling mill is caused, the system can not work normally, and the stable operation and the production efficiency of the crushing system are directly affected.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior roll mill in the using process, the utility model aims to solve the technical problem of providing roll mill feeding devices which ensure the uniform feeding.
The utility model provides a technical scheme that its technical problem adopted is:
the feeding device of the rolling mill comprises a feeding machine arranged at an outlet of a crude product bin and a constant-weight feeding weighing hopper positioned at an outlet of the feeding machine, wherein an outlet at the bottom of the constant-weight feeding weighing hopper is connected with a feeding hole of the rolling mill, and the weighing capacity of the constant-weight feeding weighing hopper is related to the feeding speed of the feeding machine.
, the feeder and the balance weight feeding weighing hopper and the rolling mill are connected with the cloth bag barrel through hoses.
, the feeder is a star feeder.
, a discharge valve is provided at the bottom outlet of the weigh hopper.
The utility model has the advantages that: through set up batcher and weighing apparatus feeding weighing hopper between crude feed bin and roll-in mill, the feed speed of batcher is adjusted according to the weighing capacity of weighing apparatus feeding weighing hopper, makes the interior material quality of weighing apparatus feeding weighing hopper stable to guarantee that roll-in mill feeding even, stable, prolonged press roller mill life, improved system production efficiency, reduced roll-in mill fault rate, whole system stability improves.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Marked in the figure as 1-crude product bin, 2-feeder, 3-weighing feeding measuring hopper, 4-rolling mill and 5-discharge valve.
Detailed Description
The present invention will be described with reference to the accompanying drawings, step .
As shown in FIG. 1, the utility model discloses a roll-in mill feed arrangement, including setting up batcher 2 in the export of crude product feed bin 1 and the weighing scale feeding weighing hopper 3 that is located batcher 2 exit, the bottom export of weighing scale feeding weighing hopper 3 links to each other with the feed inlet of roll-in mill 4, the weighing scale of weighing scale feeding weighing hopper 3 is correlated with the feed rate of batcher 2, so-called correlation means adopts some data feedback devices, makes the feed rate of batcher 2 controlled by the weighing scale feeding weighing hopper 3 to its inside material.
The utility model discloses a working process is that the material in the crude product feed bin 1 is carried to weighing feed weighing hopper 3 through batcher 2 earlier, then get into roll-in mill 4 from weighing feed weighing hopper 3's bottom export in feed process, weighing feed weighing hopper 3 can weigh its inside material in real time, and give batcher 2 with the information feedback of weighing, adjust feed speed behind the batcher 2 received information, finally make the steady quality of material in weighing feed weighing hopper 3 at certain values, because the material gets into roll-in mill 4 under the dead weight effect, the stability of material in having guaranteed weighing feed weighing hopper 3, the even stability that has just also guaranteed that the material gets into roll-in mill 4.
In order to improve the metering precision of the weighing and feeding weighing hopper 3, the feeding machine 2 and the weighing and feeding weighing hopper 3 as well as the weighing and feeding weighing hopper 3 and the rolling mill 4 are in flexible connection through hoses, cloth bag cylinders and the like.
In order to accurately control the feeding speed of the feeder 2, a star-type feeder is preferably adopted, and the feeding speed of the feeder 2 can be accurately controlled by controlling the rotating speed frequency of the star-type feeder.
In order to better control the starting and stopping of feeding, a discharge valve 5 is arranged at the bottom outlet of the weighing feeding metering hopper 3, the discharge valve 5 can be closed firstly when the feeding is started, the discharge valve 5 is opened after the material in the weighing feeding metering hopper 3 reaches quantitative quantity, the material entering the rolling mill 4 is ensured to be uniform and stable initially, and the discharge valve 5 can be closed manually and quickly after the feeding is finished or equipment fails and the like.
The utility model discloses a set up batcher and weighing feed weighing hopper between crude feed bin and roll-in mill, the feed speed of batcher is adjusted according to the weighing of weighing feed weighing hopper, makes material stable quality in the weighing feed weighing hopper to guarantee that roll-in mill feeds even, stable, prolonged compression roller mill life, improved system's production efficiency, have fine practicality and application prospect.
