Technical Field

The utility model relates to the technical field of production energy conservation, in particular to an optimization and transformation device of a vertical mill slag discharging system.

Background

In the cement production process, equipment of the vertical mill slag discharging system is in a continuous running state, but because the slag discharging amount of the vertical mill is small, most of other equipment in the slag discharging system is in an idle state, the useless loss of the equipment is increased, and a large amount of electric energy is wasted.

Disclosure of Invention

The utility model aims to solve the problems, so as to provide an optimization and reconstruction device of a vertical mill slag discharging system.

The utility model solves the problems, and adopts the following technical scheme:

the utility model provides an optimizing transformation device of vertical mill slag discharging system, includes the slag discharging conveyor that vertical mill, vertical mill slag discharging pipe mouth of pipe below set up, increases between vertical mill slag discharging pipe mouth of pipe and the slag discharging conveyor to be equipped with the surge bin, and the surge bin top is provided with the pan feeding mouth, and the pan feeding mouth that vertical mill slag discharging pipe mouth passed the surge bin top is located the surge bin inside, and the surge bin bottom is provided with the discharge gate, and discharge gate department is provided with the arc valve.

Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:

according to the utility model, the buffer bin is additionally arranged between the slag discharging pipe orifice of the vertical mill and the slag discharging conveyor, so that slag discharged by the vertical mill is buffered in the buffer bin, when the slag is buffered to a certain amount, a worker starts other equipment in the slag discharging system of the vertical mill, then opens the arc valve to discharge slag, closes the arc valve after the slag in the buffer bin is discharged, closes other equipment in the system after the slag is discharged into the whole slag discharging system, thereby reducing the use time of the other equipment in the slag discharging system, indirectly prolonging the service life of the equipment, saving a large amount of electric energy and reducing the production cost.

Preferably, the utility model further adopts the technical scheme that:

the buffer bin is respectively provided with a limit position proximity switch, an upper limit proximity switch and a lower limit proximity switch, and is respectively electrically connected with a controller arranged outside the buffer bin, and the controller is electrically connected with a control motor arranged on one side of the arc valve.

The feed inlet at the top of the buffer bin is in sealing connection with the slag discharging pipe of the vertical mill, and a height difference exists between the lower limit proximity switch and the arc valve.

FIG. 1 is a schematic view of a main body mounting structure according to an embodiment of the present utility model;

marked in the figure as: the vertical mill comprises a vertical mill body 1, a slag discharging conveyor 2, a circulating lifting machine 3, a slag discharging pipe 4 of the vertical mill body, a buffer bin 5, a limit position proximity switch 6, an upper limit position proximity switch 7, a lower limit position proximity switch 8, an arc valve 9 and a control motor 10.

Detailed Description

The utility model is further described below in connection with the following examples which are provided for the purpose of better understanding of the present utility model and are, therefore, not to be construed as limiting the scope of the utility model.

Referring to fig. 1, an optimization transformation device of a vertical mill slag discharging system comprises a vertical mill 1, a slag discharging conveyor 2 arranged below a pipe orifice of a vertical mill slag discharging pipe 4, a buffer bin 5 is additionally arranged between the pipe orifice of the vertical mill slag discharging pipe 4 and the slag discharging conveyor 2, a feeding port is arranged at the top of the buffer bin 5, the pipe orifice of the vertical mill slag discharging pipe 4 penetrates through the feeding port at the top of the buffer bin 5 and is positioned in the buffer bin 5, a discharge port is arranged at the bottom of the buffer bin 5, and an arc valve 9 is arranged at the discharge port.

The buffer bin 5 is respectively provided with a limit position proximity switch 6, an upper limit position proximity switch 7 and a lower limit position proximity switch 8, and is respectively electrically connected with a controller arranged outside the buffer bin 5, and the controller is electrically connected with a control motor 10 arranged on one side of the arc valve 9.

The feeding port at the top of the buffer bin 5 is in sealing connection with the slag discharging pipe 4 of the vertical mill, and a height difference exists between the lower limit proximity switch 8 and the arc valve 9; a certain amount of slag is always present between the lower limit proximity switch 8 and the arc valve 9, so that the air outside in the slag discharging process can be effectively prevented from flowing backwards into the machine body of the vertical mill 1, and the polishing effect of the vertical mill 1 is affected.

When the slag discharging device is used, the arc valve 9 is in a closed state, slag discharged by the vertical mill 1 is buffered in the buffer bin 5, the slag height rises, when the slag contacts with the upper limit proximity switch 7, the upper limit proximity switch 7 feeds back signals to the controller, the controller controls other equipment in the slag discharging system to operate, meanwhile, the controller sends instructions to the control motor 10 to enable the arc valve 9 to be opened, slag in the buffer bin 5 is discharged, when the slag discharging conveyor 2 and the circulating elevator 3 in the system are discharged, when the slag height in the buffer bin 5 is reduced to the lower limit proximity switch 8, the lower limit proximity switch 8 feeds back signals to the controller, the controller sends instructions to the control motor 10 to enable the arc valve 9 to be closed, after a certain time is delayed, the controller controls other equipment in the slag discharging system to stop operating, when the slag height in the buffer bin 5 reaches the upper limit proximity switch 7, the slag height can continuously rise when the arc valve 9 fails to be opened, the limit proximity switch 6 reaches the limit proximity switch 6, and the controller stops controlling the vertical mill 1 to operate.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the scope of the claims, but rather to cover all equivalent modifications within the scope of the present utility model as defined by the appended claims.
