Description

Technical Field

[0001] This utility model relates to the field of thickener technology, and more specifically, to a thickener transmission device. Background Technology

[0002] A thickener is a key piece of equipment in mineral processing, primarily used for thickening and settling concentrates such as copper, iron, and molybdenum. It is a crucial component for dewatering and separation. The drive unit is the power source for the thickener, responsible for driving the agitator in the thickening tank. Since the agitator in the thickener requires circular motion during operation and is powered by electricity, the proper functioning of the drive unit is paramount. If the drive unit stops operating, the entire thickening system will lose its thickening function, resulting in thickening failure and potentially damaging surrounding components. Because the thickening tank contains slurry, is deep, and contains a large amount of concentrate, maintenance is extremely difficult. Furthermore, a failure in the drive unit can disrupt the entire mineral processing plant's production flow, leading to a decrease in concentrate grade and increased production costs.

[0003] Currently, traditional thickener drive systems use carbon brushes for power supply. However, carbon brushes are prone to wear during long-term use, leading to poor contact and subsequent power loss, causing the thickener to shut down. Shutdown not only causes rake pressing (i.e., the mixing equipment is blocked by the slurry due to shutdown), increasing the motor load, but can even lead to motor burnout. Utility Model Content

[0004] The purpose of this invention is to provide a thickener drive device that solves the problem of frequent shutdowns in existing thickener drive devices.

[0005] This utility model is achieved through the following technical solution: a thickener transmission device, including a sliding contact line arranged on the thickener, the sliding contact line being bent into a circle arranged coaxially with the central column of the thickener, a power supply wire being connected to the outside of the sliding contact line, and a relay electrically connected to the sliding contact line being slidably connected to the inside of the sliding contact line.

[0006] Furthermore, the sliding contact line is connected to the central column via a connecting rod. One end of the connecting rod is welded to the outer wall of the central column, and the other end of the connecting rod is bolted to the outer wall of the sliding contact line.

[0007] Furthermore, several connecting rods are evenly distributed along the outer circumference of the central column.

[0008] Furthermore, a waterproof cover is installed above the sliding contact line.

[0009] Furthermore, the power supply conductors are fixed to the sliding contact line busbar using sliding contact line terminals.

[0010] Furthermore, a rubber ring is provided between the sliding contact line and the central column.

[0011] Furthermore, the sliding contact line includes several vertically parallel conductive rings.

[0012] Furthermore, the outer wall of the sliding contact line is made of stainless steel or aluminum alloy.

[0013] This utility model has at least the following advantages and beneficial effects: by coaxially connecting a coiled sliding contact line to the central column of the thickener, the relay is slidably connected to the inner side of the sliding contact line and rotates synchronously with the thickener, thus achieving a stable power supply and avoiding the problem of power loss due to poor contact. This reduces the downtime frequency of the thickener and ensures the normal operation of the thickener. Attached Figure Description

[0017] The specific implementation method is described below with reference to the accompanying drawings.

[0018] Example

[0019] like Figure 1 , Figure 2As shown, this embodiment mainly discloses a thickener transmission device, which has a simple and reliable structure, occupies little space, and is easy to maintain and replace. Its main structure includes a sliding contact line 2 mounted on the thickener. The sliding contact line 2 is bent into a circle coaxially arranged with the central column 1 of the thickener. A power supply wire 3 is connected to the outer side of the sliding contact line 2, and a relay 4, electrically connected to the sliding contact line 2, is slidably connected to the inner side of the sliding contact line 2. Specifically, the central column 1 is fixed to the tank body, and the thickener's stirring equipment is rotatably mounted inside the central column 1. The sliding contact line 2 is bent into a circle and directly coaxially connected to the central column 1, ensuring that the sliding contact line 2 remains coaxially arranged during the thickener's rotation, avoiding power loss due to poor contact. The power supply wire 3 is connected to the outer side of the sliding contact line 2, facilitating maintenance and replacement, and preventing the wire from becoming entangled or knotted during the thickener's rotation. Electromagnetic relay 4 can be used, with its rated current matching the power requirements of the thickener drive device. Relay 4 is slidably connected to the inner side of the sliding contact line 2, ensuring that relay 4 maintains good electrical contact with the sliding contact line 2 throughout the thickener's rotation. This avoids the poor contact problem caused by wear of traditional carbon brushes, thereby reducing the frequency of thickener shutdowns, preventing rake-like phenomena caused by shutdowns, reducing the risk of increased motor load, ensuring the normal operation of the thickener, preventing the decline in concentrate grade caused by shutdowns, and ensuring the dewatering process of the concentrate. The power transmission direction of this thickener is as follows: power is supplied to the sliding contact line 2 through power supply wire 3, the sliding contact line 2 supplies power to relay 4, and relay 4 supplies power to the agitation equipment.

[0020] Furthermore, in a specific implementation, the sliding contact line 2 provided in this embodiment of the invention is connected to the central column 1 via a connecting rod 5. One end of the connecting rod 5 is welded to the outer wall of the central column 1, and the other end of the connecting rod 5 is bolted to the outer wall of the sliding contact line 2. Fixing the sliding contact line 2 to the central column 1 via the connecting rod 5 enhances the structural stability of the entire transmission device and reduces loosening or displacement caused by vibration or rotation. Simultaneously, the sliding contact line 2 can be replaced as a whole, facilitating disassembly and maintenance, and improving the flexibility and maintainability of the device.

[0021] Preferably, several connecting rods 5 are evenly distributed along the outer circumference of the central column 1. The even distribution of the connecting rods 5 enhances the rigidity of the entire transmission device, reduces deformation or loosening caused by rotation or vibration, and improves the durability and reliability of the device. At the same time, it ensures that the connection between the sliding contact line 2 and the central column 1 is evenly stressed, avoiding deformation or damage caused by local stress concentration.

[0022] Furthermore, in specific implementations, a waterproof cover is provided above the sliding contact line 2 provided in this embodiment of the invention. This effectively prevents rainwater or other liquids from entering the interior of the sliding contact line 2, avoiding short circuits or power supply interruptions caused by a humid environment, ensuring the stability and continuity of the power supply, reducing corrosion and damage to electrical components such as the sliding contact line 2 and the relay 4, and extending the service life of the device.

[0023] Furthermore, in specific implementation, the power supply conductor 3 provided in this embodiment of the present invention is fixed to the sliding contact line 2 using a sliding contact line terminal 31. Specifically, the sliding contact line terminal 31 can be a copper crimp terminal with a tin-plated surface to prevent oxidation. The sliding contact line terminal 31 is designed as a U-shaped groove and is fixed to the conductive ring of the sliding contact line 2 by bolts. During connection, the terminal is covered with an insulating rubber sleeve, and waterproof sealant is applied at the connection point to prevent moisture infiltration and short circuit. The sliding contact line terminal 31 ensures a reliable connection between the power supply conductor 3 and the sliding contact line 2, avoiding power transmission interruptions or poor contact problems caused by poor connection. It also prevents wire coiling (i.e., wire tangling or knotting) during rotation, ensuring the continuity and stability of power supply.

[0024] Furthermore, in a specific implementation, a rubber ring is provided between the sliding contact line 2 and the central column 1 provided in this embodiment of the invention. On one hand, the rubber ring has good elasticity and shock absorption properties, effectively buffering the vibration and impact between the sliding contact line 2 and the central column 1, reducing wear and damage caused by vibration. On the other hand, the rubber ring has good elasticity and shock absorption properties, effectively buffering the vibration and impact between the sliding contact line 2 and the central column 1, reducing wear and damage caused by vibration.

[0025] Furthermore, in specific implementations, the sliding contact line 2 provided in this embodiment of the invention includes a plurality of vertically parallel conductive rings. This enables multi-path power supply, improving the reliability and stability of power transmission and avoiding power outages that may occur with single-path power supply. The parallel arrangement of multiple conductive rings enhances the conductivity of the sliding contact line 2, reduces power transmission losses, and improves power transmission efficiency.

[0026] Furthermore, in specific implementations, the outer wall of the sliding contact line 2 provided in this embodiment of the present invention is made of stainless steel or aluminum alloy. It possesses excellent wear resistance and corrosion resistance, enabling it to adapt to harsh working environments and extending the service life of the sliding contact line 2.
