AI Technical Summary
Traditional thickeners lack an effective material distribution device, causing the slurry to spread disorderly after entering the thickening tank, forming eddies that affect the thickening efficiency of solid materials. In addition, the fast feed speed and high kinetic energy cause the sedimented particles to float up again, reducing the thickening efficiency.
Design a material distribution device for a thickener, including a material distribution tank, a material distribution pipe and a material guide plate. By the spiral distribution of the material guide plate and the driving of the material distribution push plate, the uniform distribution of the slurry is controlled, and the impact on the thickening zone is reduced.
This achieves uniform distribution of the slurry, reduces the impact on solid materials in the concentration zone, and improves the concentration efficiency and solid material recovery rate of the thickener.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thickener technology, specifically relating to a thickener feeding device. Background Technology
[0002] Thickening is a common operation in mineral processing, and the most common thickening equipment both domestically and internationally is the thickener. Thickeners are suitable for dewatering concentrates and tailings in mineral processing plants and are widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, and environmental protection. High-efficiency thickeners are not simply sedimentation devices, but rather a new type of dewatering equipment that incorporates the filtration characteristics of slurry layers. Their basic principle is to utilize the gravity of the ore (or ore agglomerates) to settle out of the slurry, achieving desliming or dewatering.
[0003] Traditional thickeners lack a material distribution device, causing the slurry to spread randomly in all directions after entering the thickening tank. This disorder in the incoming material can easily create eddies within the tank, directly affecting the thickening process of solid materials.
[0004] Existing thickeners have seen some improvements in material distribution by adding a receiving cylinder. However, the feeding method is still simple: the slurry enters the receiving cylinder directly from the feed pipe. This results in a high feed velocity and high kinetic energy, causing the material to directly enter the bottom of the thickener's inner side. This disrupts the original balance and internal stratification of the thickener, causing some settled particles to be subjected to significant impact, leading to the re-floating of solid particles and reducing the thickener's concentration efficiency. Therefore, this application proposes a thickener material distribution device. Utility Model Content
[0005] The purpose of this utility model is to provide a material feeding device for a thickener, so as to solve the problem mentioned in the background art that the slurry enters the receiving cylinder directly from the feed pipe at a fast speed and with high kinetic energy, which causes some of the settled particles to be subjected to a large impact, resulting in the solid particles re-floating and reducing the thickener's concentration efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a material feeding device for a concentrator, comprising a concentrator body, wherein the concentrator body includes a feeding zone, a concentrating zone, and a feeding pipe, and the feeding pipe is inserted into the top of the concentrator body;

[0028] like Figures 1-4 As shown in the figure, an embodiment of this utility model provides a material feeding device for a thickener, including a thickener body 1. The thickener body 1 includes a feeding zone 101, a thickening zone 102, and a feeding pipe 103, which is inserted into the top of the thickener body 1. Raw materials enter the interior of the thickener body 1 through the feeding pipe 103, where material screening is performed to improve the mineral recovery rate.
[0029] For reference Figure 2 A feed canister 2 is inserted inside the concentrator body 1. The feed canister 2 is located within the feed area 101, specifically below the feed pipe 103. It should be noted that the outer wall of the feed canister 2 is flush with the inner wall of the shell within the concentrator body 1. A support frame 3 is mounted on the top of the feed canister 2, and the support frame 3 is also flush with the inner wall of the shell within the concentrator body 1. The feed canister 2 is mounted on the inner wall of the concentrator body 1 via the support frame 3, and the support frame 3 is connected to the inner wall of the concentrator body 1 using bolts, nuts, and other connecting components.

The guide plate 5 is spirally distributed inside the material tank 2. A guide area 501 is provided inside the guide plate 5. The guide area 501 is located in the middle of the guide plate 5. Two sets of partitions 502 that fit with the guide plate 5 are provided at both ends of the guide area 501. The partitions 502 are located on both sides of the guide area 501 and can intercept the material to prevent the material from slipping from the edge of the guide area 501.
[0031] Material falls onto the upper side of the distribution tank 2 through the feed pipe 103, and then falls from the distribution pipe 4 inserted inside the distribution tank 2 onto its respective guide plate 5. Three sets of guide plates 5 are arranged in a circumferential array around the center line of the distribution tank 2. Material on the distribution tank 2 enters the three guide plates 5 through the three distribution pipes 4. The material slides downwards along the guide area 501 in the guide plate 5 and enters the concentration area 102 at the bottom of the thickener body 1. A funnel structure can be provided at the distribution pipe 4 to cause material around the distribution pipe 4 to gather towards one side of the distribution pipe 4.
[0032] It should be noted that a filter plate 6 is provided at the bottom of the feed tank 2, and the filter plate 6 has through holes for allowing solid materials to pass through.
[0033] To push the material on the upper side of the fabric tank 2 into the distribution pipe 4, a distribution pusher plate 7 and a drive motor 8 are installed on the upper side of the fabric tank 2. Three distribution pushers 7 are arranged in a circumferential array around the center line of the fabric tank 2. The distribution pushers 7 cooperate with the output end of the drive motor 8. One end of the distribution pusher plate 7 is in contact with the upper surface of the fabric tank 2, and two sets of chamfered structures are respectively provided at both ends of the side of the distribution pusher plate 7 in contact with the upper surface of the fabric tank 2. The drive motor 8 is connected to the support frame 3 through a motor bracket. The drive motor 8 can drive the distribution pusher plate 7 to rotate, thereby driving the material on the upper side of the fabric tank 2 to rotate, so that the material enters the interior of the distribution pipe 4 and falls onto the guide plate 5.
[0034] In order to keep the material distribution push plate 7 in balance when it rotates, a guide plate 9 is provided on the material distribution push plate 7, and a guide groove 10 is provided in the support frame 3. The guide plate 9 and the guide groove 10 cooperate with each other.
[0035] In order to prevent the material entering through the feed pipe 103 from spilling onto components such as the drive motor 8, a material gathering pipe 11 is provided inside the concentrator body 1, and the feed pipe 103 is inserted into the material gathering pipe 11.
[0036] In summary, this utility model embodiment provides a material distribution device for a concentrator. The material falls onto the upper side of the material distribution tank 2 through the feed pipe 103, and then falls from the distribution pipe 4 inserted into the material distribution tank 2 onto its respective guide plate 5. Three sets of guide plates 5 are arranged in a circumferential array around the center line of the material distribution tank 2. The material on the material distribution tank 2 enters the three guide plates 5 through the three distribution pipes 4. The material slides down along the guide area 501 in the guide plate 5 and enters the concentration area 102 at the bottom of the concentrator body 1.
