Description

Technical Field

[0001] This utility model relates to the field of lifting valve technology, specifically to an electric lifting valve for a sedimentation hopper. Background Technology

[0002] The treatment of slag from waste-to-energy incineration plants involves converting it into a 30% concentration slurry, which falls through a screen into a recovery hopper. After sedimentation in a settling bin, the concentrated portion is discharged from the bottom of the settling bin and collected. Currently, the slurry flow control technology still uses manually controlled clamp valves. Because the concentration of the material processed in the settling bin changes constantly in production, manual intervention is required to control the valve opening and closing. Delays in timely intervention can lead to valve blockage or flow exceeding the processing range, affecting normal production and reducing efficiency. Therefore, there is an urgent need for a valve that eliminates the need for manual intervention while improving production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an electric lifting valve for a sedimentation hopper. The adjusting component can drive the sealing element to move up and down, so that the discharge port can be opened or closed, effectively controlling the discharge port without the need for manual intervention in valve opening and closing, and also improving production efficiency.

[0020] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an electric lifting valve for a settling hopper, comprising a feed box 1, a settling hopper 2, a discharge box 3, a sealing element 4, and an adjusting component 5. The settling hopper 2 is located at the bottom of the feed box 1, and the discharge box 3 is located at the bottom of the settling hopper 2, with a discharge port 31 at the bottom of the discharge box 3. The sealing element 4 is located inside the discharge box 3, and the adjusting component 5 is located above the sealing element 4, with its output end connected to the sealing element 4. In use, the slurry containing fine sand first enters the feed box 1, and then enters the settling hopper 2 through the feed box 1. The fine sand in the slurry settles at the bottom of the settling hopper 2 and enters the discharge box 3. At this time, the sealing element 4 is at the lowest point in the discharge box 3, blocking the discharge port 31. When it is necessary to discharge the fine sand, the adjusting component 5 moves the sealing element 4 upward, the discharge port 31 is no longer blocked, and the fine sand can be discharged from the discharge box 3 through the discharge port 31. Subsequently, the adjusting component 5 drives the sealing element 4 to move downward, and the sealing element 4 re-blocks the discharge port 31.

[0022] In use, this invention effectively controls the discharge port 31, preventing blockage and ensuring the flow rate does not exceed the processing range. Depending on actual needs, several settling hoppers 2 can be installed, allowing for simultaneous settling of fine sand. The fine sand is then discharged through different discharge ports 31. This invention facilitates production automation, eliminating the need for manual valve operation. The upward and downward movement of the sealing element 4 automatically clears the discharge port 31, protecting the environment and improving production efficiency.

[0023] Example 1

[0024] Please see Figure 1-4 In this embodiment, there are three settling hoppers 2, each with a discharge box 3 at its bottom, and each settling hopper 2 has a sealing element 4 and an adjusting component 5 inside. The feed box 1 has a slurry inlet and a slurry outlet at both ends (the slurry inlet and outlet are not shown in the diagram). In use, the slurry containing fine sand enters the feed box 1 through the slurry inlet on the left and then flows to the slurry outlet on the right (the slurry flow direction is as follows). Figure 1(As indicated by the middle arrow). During this process, the flow rate of the slurry gradually slows down, and the fine sand mixed in the slurry is precipitated out, with the concentration gradually decreasing along the slurry flow direction. The leftmost settling hopper 2 has the most fine sand precipitated and the highest concentration; the middle settling hopper 2 has the second highest sand precipitation; and the rightmost settling hopper 2 has the least sand precipitation and the lowest slurry concentration. Both the settling hopper 2 and the discharge box 3 are conical structures, so the fine sand settling in the settling hopper 2 can quickly enter the discharge box 3. The adjusting component 5 moves the sealing element 4 upward, thus discharging the fine sand. After a period of time, when the slurry concentration decreases, the adjusting component 5 moves the sealing element 4 downward to block the discharge port 31. The discharge port 31 is reopened when the concentration increases. In this embodiment, the adjusting components 5 in the leftmost sedimentation hopper 2, the middle sedimentation hopper 2 and the rightmost sedimentation hopper 2 work in sequence, so that the leftmost discharge port 31, the middle discharge port 31 and the rightmost discharge port 31 open in sequence.

[0025] Please see Figure 1-4 In this embodiment, the sealing element 4 includes a sealing flange 41 and a sealing head 42, and the adjusting assembly 5 includes a lifting motor 51, a push rod 52, an upper flange 53, a lower flange 54, and a square tube frame 55. When the adjusting assembly 5 is in operation, the lifting motor 51 drives the push rod 52 to move upwards or downwards, and the push rod 52 drives the sealing flange 41 to move upwards or downwards, ultimately causing the sealing head 42 to move away from or block the discharge port 31. When the sealing element 4 moves downwards, the sealing structure formed by the sealing flange 41 and the sealing head 42 can effectively block the discharge port 31, causing the slurry to settle again. The upper flange 53 is fixed to the feed box 1, and the lower flange 54 is fixed to the square tube frame 55 inside the settling hopper 2. The push rod 52 is concentrically constrained by the upper flange 53 and the lower flange 54, ensuring the stability of the push rod 52's movement.

[0026] Please see Figure 1-4 In this embodiment, the material box 1 and several settling hoppers 2 are all fixedly connected to the support frame 6 to ensure the stability of this utility model. The distance between the bottom of the settling hopper 2 and the bottom of the support frame 6 is greater than the height of the settling hopper 2, which facilitates the collection of fine sand discharged through the discharge port 31.

[0027] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
