Description

Technical Field

[0001] This utility model relates to the field of glass raw material conveying technology, and in particular to a bucket elevator control device. Background Technology

[0002] When two float glass production lines are adjacent, the raw material storage silos are built in the same building. The raw material silos required by the production lines are arranged horizontally, with the silos for the two production lines corresponding to each other. Bucket elevators are used to lift materials to the silos for storage. One bucket elevator can transport materials to the silos of both production lines. The bucket elevators are installed on the side of the silos, and a T-junction is installed at the discharge chute of the bucket elevator. When selecting a silo for loading, the flap inside the T-junction controls the material delivery to the selected silo according to its rotation direction.

[0003] Existing technical problems:

[0004] 1) When two production lines produce the same product, since the quality requirements of the raw materials are the same, feeding from one bucket elevator will not affect the production quality. However, when the two production lines produce differentiated products according to market conditions or production needs, the quality requirements of the raw materials change with the product demand, and the silos need to store two different raw materials. When using the same bucket elevator to feed materials to the silos of the two lines, the poor sealing of the flaps can easily cause a small amount of material to be conveyed into the unauthorized silo.

[0005] 2) Material impacting the flap can easily cause the flap to loosen, further affecting the sealing effect. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention proposes a bucket elevator discharge control structure with good sealing effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bucket elevator control device, characterized in that it includes a three-way pipe and a valve plate. The three-way pipe includes a sleeve and two material distribution branch pipes. A chute connecting to the discharge end of the bucket elevator is inserted into the sleeve. The valve plate can swing to cut off the communication between the chute and one of the material distribution branch pipes, and allow the other material distribution branch pipe to communicate with the chute. The cross-section of the sleeve and the material distribution branch pipes are both rectangular. A clearance area is formed between the sleeve and the chute to avoid the outer edge of the valve plate.

[0008] Furthermore, a support plate is hinged to each of the two ends of the valve plate that are parallel to the hinge axis of the valve plate, and a tension spring is connected between the support plate and the valve plate to reduce the angle between the valve plate and the support plate.

[0009] Furthermore, the valve plate has retaining edges at both ends perpendicular to the hinge axis of the valve plate.

[0010] This solution adds a chute to the existing three-way structure, connecting it to the bucket elevator outlet. The upward-facing part of the three-way structure, the sleeve, is fitted over the chute, with a clearance zone between the sleeve and the chute. This clearance zone ensures the valve plate's edge is within the clearance zone, guaranteeing the valve plate's outer edge is outside the chute, improving sealing and reducing leakage. Additionally, a retaining edge is added to the valve plate to further prevent material from entering areas outside the designated discharge bin. To enhance valve plate strength, a support plate is installed, transferring some of the impact force from the material to the distribution branch pipe, thus improving strength and reliability.

[0012] Legend: 1. Valve plate; 2. Sleeve; 3. Branch pipe; 4. Chute; 5. Support plate; 6. Tension spring; 7. Edge stop. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 As shown, it includes a three-way pipe and a valve plate 1. The three-way pipe includes a sleeve 2 and two branch pipes 3. A chute 4 connected to the discharge end of the bucket elevator is inserted in the sleeve 2. The valve plate 1 can swing to cut off the communication between the chute 4 and one of the branch pipes 3, and allow the other branch pipe 3 to communicate with the chute 4. The cross-section of the sleeve 2 and the branch pipes 3 are both rectangular. A clearance area is formed between the sleeve 2 and the chute 4 to avoid the outer edge of the valve plate 1.

[0015] A support plate 5 is hinged to each of the two ends of the valve plate 1 that are parallel to the hinge axis of the valve plate 1. A tension spring 6 is connected between the support plate 5 and the valve plate 1 to reduce the angle between the valve plate 1 and the support plate 5. The two ends of the valve plate 1 that are perpendicular to the hinge axis of the valve plate 1 have retaining edges 7.

[0016] This solution adds a chute 4 to the existing three-way structure. The chute 4 connects to the outlet of the bucket elevator, while the upward-facing part of the three-way structure, namely the sleeve 2, is fitted over the chute 4. A clearance area is left between the sleeve 2 and the chute 4, so that the end edge of the valve plate 1 can be located within the clearance area, ensuring that the outer edge of the valve plate 1 is outside the chute 4, thus improving the sealing effect and reducing material leakage. In addition, a retaining edge 7 is set on the valve plate 1 to further prevent material from entering the area outside the designated discharge bin. To improve the strength of the valve plate 1, a support plate 5 is provided. This support plate 5 can transfer part of the impact force of the material on the valve plate 1 to the distribution branch pipe 3, thereby improving strength and reliability.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
