Description

Technical Field

[0001] This utility model relates to the field of stabilizer addition technology, and in particular to a stabilizer addition device. Background Technology

[0002] To stabilize harmful substances in phosphorus-containing tailings solutions and prevent environmental pollution, solidification treatment of the tailings is necessary. The role of stabilizers is to react with the harmful components in the tailings to form a stable solid structure, reducing the leaching of harmful substances. Current treatment methods mostly use lime and cement as stabilizers, which can increase the pH and promote the formation of stable precipitates such as hydroxyapatite from phosphates. Cement also provides a cementing effect, solidifying and encapsulating the tailings. To ensure sufficient contact between the stabilizer (such as lime and cement) and the tailings solution, avoid local concentrations that are too high or too low, and improve the efficiency of the chemical reaction, mechanical mixing tanks or twin-shaft mixers are generally used for mixing. The current mainstream method of addition is to add the stabilizer into the mixing tank or twin-shaft mixer through a fixed feed port, supplemented by mechanical stirring to achieve mixing. However, a fixed feed port causes the stabilizer to fall in a concentrated manner, which can easily form areas with excessively high or low concentrations. This requires extending the stirring time to ensure uniformity, which not only increases energy consumption but also reduces treatment efficiency.

[0003] Therefore, it is necessary to provide a new stabilizer addition device to solve the above-mentioned technical problems. Utility Model Content

[0008] Preferably, a rod cap is fixedly installed at the bottom of the connecting rod, one end of the spring is fixedly connected to the lower surface of the sliding seat, and the other end of the spring is fixedly connected to the upper surface of the rod cap.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 The present invention provides a stabilizer adding device, which includes a feed pipe 1, a U-shaped feed rack 4 and a swing assembly 5.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 The bottom of the feed pipe 1 is fixedly fitted with a conical base 12 with the cone head facing upward, and several annularly distributed distributing ports 1a are opened on the pipe body of the feed pipe 1 near the conical base 12. An installation plate 2 is fixedly fitted on the feed pipe 1, and a hopper 11 is fixedly installed at the top opening of the feed pipe 1.

[0026] It should be noted that: the mounting plate 2 is installed on the feed inlet of the mixing tank or mixer using screws, and then the stabilizer (such as lime, cement, etc.) is added from the hopper 11 and diverted by the conical base 12 and then dispersed into the mixing tank or mixer by each feed port 1a.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 A rotating cover 3 is installed at the bottom of the conical base 12;

[0028] The rotating cover 3 is equipped with multiple U-shaped material distribution racks 4 that are arranged in a ring and rotatably connected. The U-shaped material distribution racks 4 are inclined downwards. The rotating cover 3 has multiple ring-shaped mounting cavities 3a. Each mounting cavity 3a is fixedly installed with a mounting shaft 32. The U-shaped material distribution rack 4 is connected and fixedly connected to a rotating frame 41, and the rotating frame 41 is sleeved on the mounting shaft 32 and rotatably connected to the mounting shaft 32. The bottom plate of the U-shaped material distribution rack 4 has multiple evenly distributed dropping holes 4a. The bottom of the rotating cover 3 is equipped with a swing component 5 for adjusting the dropping angle of the U-shaped material distribution rack 4.

[0029] It should be noted that when the stabilizer falls from the dispensing port 1a into the corresponding U-shaped dispensing rack 4 (some stabilizer falls directly into the mixing tank or mixer), because the U-shaped dispensing rack 4 is tilted downwards, the stabilizer can slide down along the U-shaped dispensing rack 4. At the same time, some stabilizer can be scattered downwards from the discharge hole 4a, so the stabilizer can be evenly sprinkled into the phosphorus-containing solution in the mixing tank or mixer. Since the weight of the stabilizer falling onto the U-shaped dispensing rack 4 is different each time, the U-shaped dispensing rack 4 can be tilted around the mounting shaft 32 by the swing component 5. Thus, the stabilizer falling from each U-shaped dispensing rack 4 can be dispersed and cover the phosphorus-containing solution below, further improving the uniformity of stabilizer addition.

[0030] Therefore, in this application, the conical base 12 at the bottom of the feed pipe 1 is combined with the annular dispensing port 1a, and the inclined structure and discharge hole 4a of the U-shaped dispensing frame 4 are coordinated. Under the linkage of the swing component, the U-shaped dispensing frame 4 is driven to swing by the weight of the stabilizer, which effectively realizes the multi-stage dispersion of the stabilizer and avoids the phenomenon of local accumulation.

[0031] In this embodiment: a rotating ring groove 1b is provided on the outer ring wall of the conical base 12, and a connecting ring 31 is fixedly installed on the inner ring wall of the rotating cover 3. The connecting ring 31 is sleeved in the rotating ring groove 1b and fixedly connected to the rotating ring groove 1b to avoid misalignment between the U-shaped material distribution frame 4 and the material distribution port 1a.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4 The swing assembly 5 includes a central connecting rod 51, which is fixedly installed at the bottom of the rotating cover 3. A rod cap 511 is fixedly installed at the bottom of the central connecting rod 51, and a sliding seat 52 is slidably connected on the central connecting rod 51. An abutment plate 53, which is rotatably connected to the U-shaped material distribution frame 4, is installed on the sliding seat 52. One end of the abutment plate 53 is rotatably connected to the sliding seat 52 through the rotating frame, and the other end of the abutment plate 53 is rotatably connected to the docking shaft frame 42, which is fixedly installed at the bottom of the U-shaped material distribution frame 4. A spring 54 is sleeved on the central connecting rod 51. One end of the spring 54 is fixedly connected to the lower surface of the sliding seat 52, and the other end of the spring 54 is fixedly connected to the upper surface of the rod cap 511.

[0033] It should be noted that when the stabilizer falls onto the U-shaped distribution rack 4, the U-shaped distribution rack 4, under the action of gravity, presses down on the sliding seat 52 through the abutment plate 53. At this time, the spring 54 is compressed. When the amount of stabilizer on the U-shaped distribution rack 4 decreases, the spring 54 continuously extends and retracts. Therefore, the sliding seat 52 can slide up and down along the central connecting rod 51, so the U-shaped distribution rack 4 can continuously swing and drop the material.

[0034] To avoid the potential for spring 54 to fail due to prolonged high-frequency expansion and contraction, spring 54 is made of high fatigue strength alloy spring material to extend its service life.

[0035] Furthermore, two symmetrically distributed limiting plates 521 are fixedly installed on the inner wall of the sliding seat 52, and the two limiting plates 521 are respectively inserted into the two symmetrically distributed sliding grooves 51a opened on the central connecting rod 51 and slidably connected to the sliding grooves 51a to avoid the potential risk of the sliding seat 52 deflecting around the central connecting rod 51.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
