Description

Stability-increasing belt type constant feeder

Technical Field

The utility model relates to a further belt batcher of stabilizing the unloading especially relates to an increase stable belt batcher.

Background

Currently, the methods are as follows: in the daily industrial production process of coal, ore powder, grain, cement and the like, when particles, powder and the like are continuously fed and measured, a belt type constant feeder is generally adopted for feeding. The existing belt type constant feeder is generally provided with a weighing sensor, the weighing sensor feeds weight information back to a controller, the controller controls the rotating speed of a drum driving motor connected with the controller, when the weight is larger than a preset value, the controller reduces the rotating speed of the drum driving motor so as to reduce the blanking amount, when the weight is smaller than the preset value, the controller improves the rotating speed of the drum driving motor so as to improve the blanking amount, and finally the stability of the blanking amount is kept to meet the requirement of subsequent processing. However, the conventional belt type constant feeder needs to be weighed first to adjust the rotating speed of the driving roller in a targeted manner, has certain hysteresis in the control process, often causes the situation of material rushing out due to material spewing when feeding is concentrated, and is difficult to ensure the stability of feeding.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of prior art to a provide a increase stable belt formula constant feeder, it can avoid the material to spout the appearance of phenomenon, keeps the stability of unloading.

In order to achieve the above object, the utility model discloses the technical scheme who adopts includes: the frame is equipped with driving pulley and turnabout drum in the frame, is equipped with more than one bearing roller between driving pulley and turnabout drum, is equipped with weighing sensor on wherein at least one bearing roller, and driving pulley, turnabout drum and bearing roller outer loop are around the belt, and driving pulley connection drum driving motor, the top of belt one end is equipped with steady workbin, and steady workbin includes: the box, the box is equipped with import and export, is equipped with the baffle in the box, is equipped with the perforation on the baffle.

And a first gate valve is arranged at the outlet.

The belt is also provided with a second gate valve, and a valve plate of the second gate valve is positioned above the belt.

And a shell is arranged above the belt.

And a limiting device is arranged below the valve plate of the second gate valve.

The utility model discloses an adopt steady workbin, the condition of dashing the material can not appear in the feeding that makes the powder feeder to the ejection of compact that keeps the powder feeder keeps relative stability, and then does not influence the work of other equipment. And secondly, a first inserting plate valve is arranged at the outlet of the material stabilizing box to control the upper limit of blanking, so that blanking is more stable and is not affected by sudden overlarge feeding. And thirdly, a second gate valve is arranged at the belt to further control the upper limit of the blanking, so that the blanking peak value is relatively gentle, and the stability of the blanking is further guaranteed. Fourthly, the shell is arranged above the belt, so that air pollution caused by flying of dust in the discharging process is effectively prevented.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1, the embodiment of the present invention includes: frame 1 is equipped with driving pulley 2 and turnabout drum 3 in the frame 1, is equipped with more than one bearing roller 4 between driving pulley 2 and turnabout drum 3, is equipped with weighing sensor on at least one of them bearing roller 4, and driving pulley 2, turnabout drum 3 and bearing roller 4 encircle belt 5 outward, and driving pulley 2 connects drum driving motor, the top of belt 5 one end is equipped with steady workbin 6, and steady workbin includes: the box, the box is equipped with import 601 and export, is equipped with two baffles 602 in the box, and two baffles are the chevron shape and arrange, and the baffle is the slope and sets up in order to make things convenient for the powdery material to get into the export. The partition 602 is provided with a strip-shaped through hole 603, and the through hole 603 facilitates the powder material to flow from the through hole to the discharge port. The outlet is provided with a first gate valve 7, and the first gate valve 7 controls the flow of the material passing through the gate valve through the change of the opening and closing area of the valve plate, so that the upper limit of the material passing through the gate valve is effectively limited. The belt 5 is also provided with a second gate valve 8, a valve plate 801 of the second gate valve 8 is positioned above the belt 5, the moving direction of the valve plate 801 is perpendicular to the moving direction of the belt 5, and the valve plate 801 controls the blanking volume through the change of the gap size between the valve plate 801 and the belt 5. The second gate valve 8 blocks the current-limiting effect and makes the unloading volume remain stable, prevents that too much material from passing through from second gate valve 8, reduces the influence to subsequent processing. A limiting device 802 is arranged below the valve plate 801 of the second gate valve 8, and the limiting device 802 is a limiting plate, and the upper edge of the limiting plate is higher than the belt. When the valve plate 801 of the second gate valve 8 is closed, the valve plate 801 and the belt are enabled to have a gap, the valve plate is prevented from falling to collide with the belt, and therefore normal operation of the belt is blocked. The utility model discloses a set up two push-pull valves and do: the first gate valve 7 and the second gate valve 8 limit the blanking flow in two stages, so that the upper limit of the blanking amount can be more accurately limited. The top of belt 5 is equipped with shell 9, makes the conveying of material be in the encapsulated situation, has effectively reduced the influence to operational environment. One end of the shell 9 is provided with a feed opening 10.

As the improvement of the utility model, the utility model discloses also can only adopt the upper limit of first push-pull valve control unloading volume.

While the foregoing description of the disclosed embodiments will enable one skilled in the art to make or use the invention, various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Therefore, all technical solutions the same as or similar to the present embodiment fall within the protection scope of the present invention.
