Description

Technical Field

[0001] This utility model relates to the field of mining equipment, and in particular to a chemical dosing mechanism for a concentrator. Background Technology

[0002] Thickeners are commonly used mechanical separation equipment in the coal mining industry. Their process involves adding flocculants to make materials settle quickly, thereby achieving tailings dewatering.

[0003] Existing thickeners are typically quite large. To ensure the flocculant is evenly distributed within the thickener's chamber, current methods usually involve using a large-area pipe network to distribute the flocculant inside the tank. The most significant drawback of this method for mining equipment is the difficulty and high cost of maintenance; unblocking is cumbersome, and dealing with pipe blockages is extremely difficult. Furthermore, this type of pipe network arrangement increases production costs and assembly complexity during equipment manufacturing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a concentrate dosing mechanism that is more convenient to assemble and use and has a lower chance of pipe blockage while ensuring uniform flocculant dispensing.

[0005] The dosing mechanism of the concentrator is fixedly installed on the top plate of the concentrator, using the top plate of the concentrator as the assembly base.

[0006] The equipment includes a dosing machine, a storage box, and a flocculant spreading mechanism;

[0007] The dosing machine is connected to a storage box, which is fixedly mounted on the top plate of the concentrator.

[0008] The flocculant spreading mechanism includes a drug tube that passes through a storage box and is rotatably mounted inside the storage box. A through hole is provided on the section of the drug tube inside the storage box. The bottom of the drug tube passes through the bottom plate of the concentrator and is provided with a downwardly inclined spreading section.

[0009] The aforementioned drug tube power connection rotating mechanism.

[0010] The effect achieved is that the flocculant enters the storage box through the dosing machine, and the flocculant in the storage box falls through the through hole on the dosing tube; and based on the rotation of the rotating mechanism, the spreading section of the dosing tube evenly spreads the flocculant inside the concentrator's chamber.

[0011] The beneficial effects of this utility model are: This utility model solves the many drawbacks of the existing thickener dosing system, and achieves uniform feeding with lower cost and more convenient maintenance while ensuring uniform flocculant dispensing; in particular, the equipment has a lower chance of pipe blockage compared with the traditional flocculant adding pipeline.

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 , Figure 2 The dosing mechanism for a concentrator described in this utility model is fixedly installed on the top plate of the concentrator, using the top plate of the concentrator as the assembly base.

[0018] The equipment includes a dosing machine 1, a storage box 2, and a flocculant spreading mechanism;

[0019] The dosing machine 1 is connected to the storage box 2 by a pipeline, and the storage box 2 is fixedly installed on the top plate of the concentrator;

[0020] The flocculant spreading mechanism includes a drug tube 4, which passes through the storage box 2 and is rotatably disposed inside the storage box 2. The drug tube 4 has a through hole 41 on the tube section inside the storage box 2. The bottom of the drug tube 4 passes through the bottom plate of the thickener and has a downwardly inclined spreading section 42 at the bottom.

[0021] The medicine tube 4 is powered to rotate the mechanism 3.

[0022] Example 1: The dosing machine 1 is a dosing machine 1 equipped with a motor and a feeding auger.

[0023] The effect achieved is to ensure that the flocculant is continuously delivered to the storage box 2 by the screw conveyor, and based on the continuous delivery method into the storage box 2, to ensure that the flocculant can smoothly enter the through hole 41 on the drug tube 4.

[0024] In Example 2, a mechanical seal is provided between the storage box 2 and the medicine tube 4.

[0025] The effect achieved in this way is to prevent the spillage of flocculants or other medications.

[0026] In Example 3, the medicine tube 4 has multiple through holes 41 arranged in an array. The through holes 41 are rectangular holes, and a mechanical seal is provided near the bottom of the hole.

[0027] This achieves the effect of further ensuring smooth material feeding.

[0028] In Example 4, the rotating mechanism 3 is a servo motor, and the servo motor is connected to the medicine tube 4 via a coupling.

[0029] Preferably, the servo motor signal is connected to the controller, and the controller controls the automatic timed feeding.

[0030] Example 5, refer to the accompanying drawings in the specification. Figure 1 or Figure 2 The medicine tube 4 is an integral unit, and its dispensing section 42 is provided with one or more parts;

[0031] When there are multiple dispensing segments 42, they are arranged in a uniform array around the drug tube 4.

[0032] During use, the flocculant enters the storage box 2 through the dosing machine 1, and the flocculant in the storage box 2 falls through the through hole 41 on the dosing tube 4; and based on the rotation of the rotating mechanism 3, the spreading section 42 of the dosing tube 4 spreads the flocculant evenly inside the cavity of the thickener.
