Description

Technical Field

[0001] The utility model relates to the field of material conveying, in particular to a material replenishment signal device for a closed-type feeder transition hopper. Background Art

[0002] At present, closed feeders are widely used in glass kilns. The transition hopper at the feed port of the closed feeder needs to be sealed with the glass formula mixture to be melted. The material in the transition hopper will decrease during the operation of the closed feeder, and it needs to be blocked again when the feeder stops running. Therefore, a material detection device must be installed on this hopper. At present, the market widely uses a rotary material sensor or a microwave material sensor to detect the material situation in the silo, so as to control the feeder in real time to refill the transition hopper to meet the process requirements. This patent relates to a closed feeder transition hopper refilling signal device.

[0003] In actual use, 1600℃ heat in the kiln will radiate from unsealed places such as the feeding port. The feeder is often installed at the feeding port of the kiln, which will cause the ambient temperature around the feeder to be too high. The rotary material sensor is often damaged due to high temperature. Once the transition hopper on the upper part of the feeder is short of material or has no material, the temperature of the glass kiln will radiate through the feeding cavity of the feeder, which will burn out the feeder over time; or once the material is blocked, the area around the feeder will be full of glass mixed raw materials, affecting the environment and wasting raw materials.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific drawings.

[0018] Example:

[0019] like Figure 1 , Figure 2As shown, a closed feeder transition hopper refill control signal device includes a rotating rod 2 rotatably arranged in the hopper 1, a baffle adjustment structure 3 at the middle position of the rotating rod 2 and a material detection baffle 4, the material detection baffle 4 is arranged downward, one end of the rotating rod 2 extends out of the hopper 1 and is installed with a signal transmission rod 5, the outer wall of the hopper 1 is provided with a metal sensor 6, when there is no material in the hopper 1, the material detection baffle 4 is vertically downward, the signal transmission rod 5 is flush with the metal sensor 6, and the end of the signal transmission rod 5 points to the metal sensor 6, the distance is 5mm, and the metal sensor 6 senses the signal for feedback.

[0020] In this embodiment, the signal transmission rod 5 is made of a metal rod.

[0021] When the material detection baffle 4 is squeezed by the glass mixed raw materials, it will deflect, driving the rotating rod 2 to move at an angle with the center of the rod axis as the center. At this time, the signal transmission rod 5 is driven to deflect, and the end of the signal transmission rod 5 is farther away from the metal sensor 6, and there is no signal output, which proves that no material is needed. When there is no material in the hopper 1, the rotating rod 2 is affected by the deadweight of the material detection baffle 4, driving the signal transmission rod 5 to be flush with the metal sensor 6, and the end of the signal transmission rod 5 points to the metal sensor 6. The metal sensor 6 senses the signal and gives feedback to replenish the material.

[0022] The connection node between the rotating rod 2 and the signal transmission rod 5 is biased toward one end of the transmission rod, and a weight balance adjustment block 7 is arranged at one end.

[0023] In the above structure, the rotation point of the signal transmission rod 5 is not located in the middle, but close to one side, so that the free end on the other side can swing farther at the same swing angle, better severing the connection with the metal sensor 6 and reducing misjudgment.

[0024] One end of the signal transmission rod 5 is processed with a threaded wire, and the weight balance adjustment block 7 is provided with a threaded hole through which one end of the signal transmission rod 5 is screwed into the threaded hole. The purpose is to adjust the specific position of the weight balance adjustment block 7.

[0025] A 45 degree sector angle slot 8 is formed at one end of the rotating rod 2, and a vertical limiting rod 9 is provided on the hopper 1, and the free end of the vertical limiting rod 9 is located in the 45 degree sector angle slot 8. The purpose is to limit the rotation angle of the rotating rod 2.

[0026] It should be noted that, in this embodiment, the signal sensed by the metal sensor 6 can be fed back to the control system, and the control system controls the switch for adding upstream materials, thereby realizing automatic material replenishment.
