Description

Technical Field

[0001] This utility model belongs to the field of thickener feeding technology, and in particular relates to a dosing mechanism for the central cylinder of a tailings thickener. Background Technology

[0002] When a tailings thickener is in operation, flocculant needs to be added to its central cylinder to promote the rapid settling of solid particles in the slurry and achieve solid-liquid separation. By properly controlling the amount of flocculant added, the thickener's operating performance can be optimized, ensuring that tailings particles can quickly solidify and settle, avoiding problems such as overflow, turbidity, and the formation of isolated sedimentary islands. However, in practice, the amount of flocculant added is difficult to control, causing the thickener to fail to achieve the desired operating effect. Furthermore, during the process of adding flocculant to the thickener's central cylinder, the flocculant can easily remain in the delivery pipes, further hindering the thickener's performance and preventing the slurry from solidifying into the required state.

[0003] To address these issues, we provide a dosing mechanism for the central cylinder of a tailings thickener. Utility Model Content

[0004] The purpose of this utility model is to provide a dosing mechanism for the central cylinder of a tailings thickener. By fixing a weighing platform to the lower side of the dosing cylinder in the weighing assembly, flocculants and other drugs are poured into the dosing cylinder from the dosing pipe at the upper end of the dosing cylinder. The weighing platform detects the weight of the flocculants in the dosing cylinder, thereby controlling the amount of added drugs. By sliding a pusher piston in the pushing assembly inside the dosing cylinder, the pusher piston pushes the flocculants in the dosing cylinder into the central cylinder of the thickener, ensuring that no flocculants remain in the dosing cylinder and preventing inconsistent weight of added flocculants.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a dosing mechanism for the central cylinder of a tailings thickener, comprising a weighing component and a pushing component. The weighing component includes a dosing cylinder and a weighing platform, and the pushing component includes a pushing cylinder and a pushing piston.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figures 1 to 4 This utility model relates to a dosing mechanism for the central cylinder of a tailings thickener, comprising a weighing component 1 and a pushing component 2. The weighing component 1 includes a dosing cylinder 101 and a weighing platform 102, and the pushing component 2 includes a pushing cylinder 201 and a pushing piston 202. By fixing the weighing platform 102 to the lower side of the dosing cylinder 101 in the weighing component 1, flocculants and other chemicals are poured into the dosing cylinder 101 from the dosing pipe 101a at the upper end of the dosing cylinder 101. The weighing platform 102 detects the weight of the flocculant in the dosing cylinder 101, thereby controlling the amount of chemicals added. By sliding the pushing piston 202 in the pushing component 2 inside the dosing cylinder 101, the pushing piston 202 pushes the flocculant in the dosing cylinder 101 into the central cylinder of the thickener, ensuring that no flocculant remains in the dosing cylinder 101 and preventing inconsistent weight of the added flocculant.

[0027] Specifically, the inlet cylinder 101 has a horizontal cylindrical structure. An inlet pipe 101a is provided at the upper end of the inlet cylinder 101. The weighing platform 102 is fixedly installed on the lower side of the inlet cylinder 101. A horizontal frame 102a is fixed at one end of the weighing platform 102. The push cylinder 201 is installed above the horizontal frame 102a. The push piston 202 is slidably sleeved inside the inlet cylinder 101. The telescopic end of the push cylinder 201 is connected to the end face of the push piston 202 near the push cylinder 201.

[0028] Furthermore, a cylinder bracket 102a-1 is fixed on the crossbeam 102a, and a push cylinder 201 is installed on the cylinder bracket 102a-1 for mounting the push cylinder 201.

[0029] Furthermore, connecting arms 202a are fixedly provided on both sides of the end face of the push piston 202 away from the push cylinder 201. A cover 202b is fixedly provided on the end of the connecting arm 202a away from the push piston 202. When the push piston retracts, the medicine enters the medicine inlet cylinder 101 from the medicine inlet pipe 101a. At the same time, the cover 202b blocks the medicine to prevent the medicine from falling from the outlet end of the medicine inlet cylinder 101. When the push piston 202 pushes forward, it pushes the medicine in the medicine inlet cylinder 101 out from the outlet end.

[0030] Furthermore, an adapter 202c is fixedly provided on one end face of the push piston 202 near the push cylinder 201. The adapter 202c is a U-shaped structure with its opening facing the push piston 202. An adapter through hole 202c-1 is provided on the horizontal top plate of the adapter 202c. A top receiving plate 201a is fixedly provided on the telescopic end face of the push cylinder 201. An internal threaded sleeve 201a-1 is provided on the end face of the top receiving plate 201a away from the push cylinder 201. A through rod 201b is sleeved on the internal threaded sleeve 201a-1. The through rod 201b passes through the adapter through hole 202c-1. A retaining plate 201b-1 is fixedly provided on the end of the through rod 201b away from the top receiving plate 201a.

[0031] Furthermore, the diameter of the through rod 201b is smaller than the diameter of the transition hole 202c-1, so that the extension and retraction end of the push cylinder 201 will not exert weight on the push piston 202, ensuring that the weight inside the injection cartridge 101 will not be affected by the push cylinder 201.

[0032] The operation process in this embodiment is as follows:

[0033] When the push piston retracts, the medicine enters the medicine inlet cylinder 101 from the medicine inlet pipe 101a. At the same time, the baffle 202b blocks the medicine to prevent it from spilling out of the outlet end of the medicine inlet cylinder 101. When the weight of the added medicine reaches the set value, the push cylinder 201 pushes the push piston 202 to move. When the push piston 202 pushes forward, it pushes the medicine in the medicine inlet cylinder 101 out of the outlet end, thus completing the weighing and discharge of the medicine. Example 2

[0034] Please see Figures 1 to 5 Based on Example 1, the weighing assembly 1 also includes a drug outlet cover 103, which restricts the direction of the drug being pushed out of the drug inlet cylinder 101, so that the drug falls vertically downwards and prevents the drug from scattering.

[0035] Specifically, a drug outlet cover 103 is fixedly installed at the end of the drug inlet cylinder 101 away from the push cylinder 201. The end of the drug outlet cover 103 near the drug inlet cylinder 101 is connected to the drug inlet cylinder 101. A drug outlet 103a is opened on the lower side plate of the drug outlet cover 103.

[0036] Furthermore, the medicine dispensing cover 103 also includes a medicine dispersing tray 103b. The medicine dispensing cover 103 has a suspension beam 103a-1 fixed at the medicine dispensing port 103a. A connecting rod 103b-1 is fixed at the upper end of the medicine dispersing tray 103b, and the connecting rod 103b-1 is fixedly connected to the suspension beam 103a-1.

[0037] Furthermore, the dispersing disc 103b has an upward-convex conical structure. After the medicine falls on the dispersing disc 103b, it spreads outwards and falls evenly into the central cylinder of the thickener.

[0038] The operation process in this embodiment is as follows:

[0039] The agent falls downward from the discharge hood 103 until it lands on the dispersing tray 103b, where it spreads outwards and evenly falls into the central cylinder of the thickener.
