Description

Technical Field

[0001] This utility model relates to the technical field of phosphate removal, and in particular to a phosphate removal device. Background Technology

[0002] Phosphoric acid salts are all solids, and their solubility increases in the order of normal salt, monohydrogen salt, and dihydrogen salt. Phosphoric acid reacts with sufficient alkali to form normal salts. Naturally occurring phosphates are phosphate rock (containing calcium phosphate). Phosphate can be produced by reacting phosphate rock with sulfuric acid to produce calcium dihydrogen phosphate and calcium sulfate, which can be absorbed by plants.

[0003] In the current phosphate production process, flocculants are widely used in the impurity removal stage. The specific operation process is as follows: the flocculant is injected into a sedimentation tank containing phosphate stock solution, and then the flocculant and phosphate stock solution are thoroughly mixed using a stirring mechanism, which causes the heavy metal ions in the stock solution to coagulate and settle to the bottom of the tank. Finally, the upper layer of stock solution is taken out, completing the impurity removal step.

[0004] However, in traditional processes, the agitator is usually placed in the middle of the settling tank, and the flocculant and phosphate stock solution are mixed by rotation. But this method is prone to causing vortices to form in the solution inside the tank, resulting in unidirectional inertial flow, which in turn affects the efficiency of impurity removal in phosphate production. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a purification device for phosphate preparation. By combining a stirring mechanism and a turbulence-inducing component, the stirring effect can be improved while accelerating the mixing of flocculant and raw materials, and the purification operation time can be shortened, thereby improving the purification efficiency.

[0007] To achieve the above objectives, this utility model proposes a purification device for phosphate preparation, comprising a tank and a stirring mechanism and a turbulence-disrupting assembly disposed within the tank. The stirring mechanism includes a first stirring element and a second stirring element. The first stirring element includes a rotating shaft and multiple first stirring blades disposed outside the rotating shaft. The rotating shaft is located in the middle of the tank via a driving component. The second stirring element is disposed outside the first stirring element and the two are connected. The turbulence-disrupting assembly is disposed between the first and second stirring elements and includes a fixing element and multiple turbulence-disrupting plates. The fixing element is vertically arranged, with its upper end penetrating the tank and having an adding portion. The fixing element has a channel, one end of which is connected to the adding portion, and the other end has multiple one-way adding ports, each with a one-way valve. Each turbulence-disrupting plate is correspondingly disposed between two adjacent first stirring blades, and one end of the turbulence-disrupting plate is connected to the fixing element.

[0008] In addition, the phosphate preparation purification device proposed in the above application may also have the following additional technical features:

[0009] Specifically, the second stirring component includes a connecting arm, a fixed shaft, and a second stirring blade, wherein the upper and lower sides of the fixed shaft are respectively connected to the second stirring blade and the connecting arm, and the connecting arm is connected to the rotating shaft.

[0010] Specifically, the connecting arm is V-shaped, the bent part of the connecting arm is connected to the fixed shaft, and the upper end of the connecting arm is fixedly connected to the rotating shaft, while the lower end is movably connected to the outlet at the bottom of the tank.

[0011] Specifically, the lower end of the connecting arm is provided with a plurality of circumferentially distributed support plates, which slide against the inner wall of the outlet.

[0012] Specifically, the plurality of first stirring blades are divided into multiple vertical columns, with the plurality of first stirring blades in each column being parallel and the first stirring blades in adjacent columns being symmetrical.

[0013] Specifically, each column of the first stirring blade corresponds one-to-one with the turbulence assembly.

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The impurity removal device for phosphate preparation according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown, the phosphate preparation impurity removal device of this utility model embodiment may include a tank 10 and a stirring mechanism (not shown in the figure) and a turbulence component 30 disposed in the tank 10. The upper side of the tank 10 is provided with an inlet 101, the lower side of the tank 10 is provided with an outlet 102, and the bottom of the tank 10 may be arranged in a downward cone shape, with the outlet 102 located at the middle position of the bottom of the tank 10.

[0028] The stirring mechanism may include a first stirring element 201 and a second stirring element 202. The first stirring element 201 may include a rotating shaft 2011 and a plurality of first stirring blades 2012 disposed outside the rotating shaft 2011. The rotating shaft 2011 is disposed in the middle of the tank body 10 via a driving member 40. The driving member 40 is disposed on the tank body 10. The plurality of first stirring blades 2012 are divided into multiple vertical columns. The plurality of first stirring blades 2012 in each column are parallel, and adjacent columns of first stirring blades 2012 are symmetrical. Each column of first stirring blades 2012 corresponds one-to-one with the turbulence-disrupting component 30.

[0029] It should be noted that the drive unit 40 described in this embodiment has the function of controlling the rotation of the rotating shaft 2011. The drive unit 40 can be a motor, and the output end of the drive unit 40 is directly connected to the rotating shaft 2011.

[0030] The second stirring element 202 is located outside the first stirring element 201 and the two are connected. The second stirring element 202 may include a connecting arm 2021, a fixed shaft 2022, and a second stirring blade 2023. The upper and lower sides of the fixed shaft 2022 are respectively connected to the second stirring blade 2023 and the connecting arm 2021. The connecting arm 2021 is connected to the rotating shaft 2011. The connecting arm 2021 is V-shaped. The bent part of the connecting arm 2021 is connected to the fixed shaft 2022. The upper end of the connecting arm 2021 is fixedly connected to the rotating shaft 2011, and the lower end is movably connected to the outlet 102 at the bottom of the tank 10. The lower end of the connecting arm 2021 is movably embedded in the outlet 102. The lower end of the connecting arm 2021 is provided with multiple circumferentially distributed support plates 20211, which slide against the inner wall of the outlet 102. A valve (not shown in the figure) is provided in the outlet 102, which can control the opening state of the outlet 102. When the connecting arm 2021 rotates with the rotating shaft 2011, multiple support plates 20211 rotate within the outlet 102, thereby limiting the rotation of the connecting arm 2021 and contributing to the overall stability of the stirring mechanism's rotation.

[0031] The connecting arm 2021 described in this embodiment can connect the rotating shaft 2011 and the fixed shaft 2022, so that when the rotating shaft 2011 rotates, it can directly drive the first stirring blade 2012 to rotate, and at the same time, it can indirectly drive the second stirring blade 2023 to rotate through the connecting arm 2021 and the fixed shaft 2022. Through the synergistic effect of the first stirring element 201 and the second stirring element 202, the solution in the tank is thoroughly stirred.

[0032] The turbulence-dissipating assembly 30 is disposed between the first stirring blade 201 and the second stirring blade 202, and may include a fixing member 301 and multiple turbulence-dissipating plates 302. The fixing member 301 is vertically arranged, and its upper end penetrates the tank body 10 and is provided with an adding part 3011. The fixing member 301 is provided with a channel 3012. One end of the channel 3012 is connected to the adding part 3011, and the other end is provided with multiple one-way adding ports 3013. The multiple one-way adding ports 3013 are arranged vertically in sequence. The one-way adding ports 3013 are provided with one-way valves 30131, which can prevent liquid in the tank from entering the channel 3012 from the one-way adding ports 3013. Each turbulence-dissipating plate 302 is correspondingly disposed between two adjacent first stirring blades 2012, and one end of the turbulence-dissipating plate 302 is connected to the fixing member 301.

[0033] It should be noted that, through the addition section 3011 described in this embodiment, flocculant can be introduced into the channel 3012 and evenly discharged to different horizontal levels in the tank through multiple one-way addition ports 3013, thereby promoting the full mixing of flocculant and solution. During the flocculant addition process, it can be pressurized to accelerate the flocculant into the channel 3012 and smoothly discharge it from the one-way addition port 3013.

[0034] Specifically, in the actual process of removing impurities from phosphate, relevant personnel can first add phosphate stock solution into the tank through inlet 101, and then add flocculant into channel 3012 through addition section 3011.

[0035] During the addition of phosphate stock solution and / or flocculant, relevant personnel can operate the stirring mechanism through the drive unit 40 to fully stir the solution in the tank. Specifically, when the drive unit 40 is started, the drive unit 40 directly drives the rotating shaft 2011 connected to it to rotate. The rotating shaft 2011 can then drive the first stirring blade 2012 and the second stirring blade 2023 to rotate synchronously. The first stirring blade 2012 and the second stirring blade 2023 work together to fully stir the solution in the tank. The baffle 302 located between the two can turbulent the solution acted upon by the stirring mechanism, effectively preventing the formation of vortices and unidirectional inertial motion in the solution in the tank, thus ensuring the efficient removal of impurities in phosphate production.

[0036] After the solution in the tank is fully stirred, the relevant personnel can control the drive unit 40 to stop running, and then extract the upper layer of raw liquid through the inlet 101. Finally, open the valve in the outlet 102 so that the lower layer of sediment can be discharged through the outlet 102. During the process, the relevant personnel can control the rotating shaft 2011 to rotate, so that the support plate 20211 rotates in the outlet 102, thereby effectively preventing the outlet 102 from being blocked.

[0037] In summary, the phosphate preparation impurity removal device of this utility model, through the combination of a stirring mechanism and a turbulence-inducing component, can improve the stirring effect while accelerating the mixing of flocculant and raw materials, and can also shorten the impurity removal operation time, thereby improving the impurity removal efficiency.
