Description

Technical Field

[0001] The present application relates to the technical field of ferric phosphate production, and in particular to a ferrous phosphate settling tank. Background Art

[0002] Ferric phosphate, also known as high iron phosphate and orthoferric phosphate, has a molecular formula of FePO4 and is a white or off-white monoclinic crystalline powder. Ferric phosphate is a salt formed by the reaction of an iron salt solution and sodium phosphate, in which the iron is trivalent. Its main use is in the manufacture of lithium iron phosphate battery materials, catalysts and ceramics. One of the production processes of iron phosphate is as follows:

[0003] The ferrous sulfate solution, diammonium phosphate solution, sulfuric acid and oxidant in the raw material storage tank are pumped into the metering tank respectively, and are metered into the kettle in order through the metering tank for stirring and reaction, and the reaction temperature is maintained at 80-90°C. After the reaction is completed, the material in the kettle is pumped into the intermediate liquid receiving tank. The intermediate liquid receiving tank is pumped to maintain circulating stirring; the material in the intermediate liquid receiving tank is pumped into the filter press, and is washed 4 times after filtration in the plate and frame filter press; the waste liquid after washing is collected and sent to the waste liquid treatment system for treatment; the filter cake filtered out is sent to the drying system for drying; the filtered filter cake is sent to the rotary flash dryer for drying and granulation. After granulation, it is vacuum transported to the packaging machine for packaging and then transported to the warehouse for storage. Among them, in the above production steps, it is necessary to use a precipitation tank to precipitate the ferrous sulfate solution.

[0004] For example, Chinese patent application number 201110108433.5 discloses a continuous sedimentation tank, including a shell, the upper part of the shell is a circular cylinder, the lower part is a conical cylinder, an overflow weir is arranged in the circular cylinder, and a bottom flow outlet is arranged at the bottom of the conical cylinder. An arched feed trough is arranged in the circular cylinder of the shell, and the arched feed trough is composed of an inner side wall of the circular cylinder, a straight wall plate, a grid distribution plate and a bottom plate. The grid distribution plate is arranged below the straight wall plate, and its upper and lower ends are respectively fixedly connected to the straight wall plate and the bottom plate; a plurality of porous guide plates are symmetrically and obliquely arranged on the outside of the straight wall plate, and a gap is left between the guide plates and the straight wall plate; a rotating rake is arranged in the conical cylinder at the lower part of the shell.

[0005] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0006] During the precipitation treatment of ferrous sulfate solution, some precipitates will be attached to the inner sloping wall of the conical cylinder to a greater or lesser extent. Some of the precipitates are very sticky and cannot slide down the inner sloping wall of the conical cylinder to the discharge port at the bottom of the conical cylinder due to gravity. If these precipitates are not cleaned regularly, they will easily deteriorate over time, thus affecting the quality of the final ferric phosphate product. Therefore, it is necessary to arrange staff to enter the sedimentation tank regularly for cleaning, which is time-consuming and labor-intensive, and needs to be improved. Summary of the invention

[0040] The following is combined with Figure 1-3 This application is described in further detail.

[0041] The present application embodiment discloses a ferrous iron settling tank. Figure 1 and Figure 2 The ferrous sedimentation tank comprises a frame 1 and a circular cylinder 2 and a conical cylinder 3 made of glass fiber reinforced plastic. The conical cylinder 3 is installed on the frame 1. The top of the conical cylinder 3 is connected to the bottom of the circular cylinder 2. A feed port 21 is arranged on the top of the circular cylinder 2. A safety guardrail is also arranged on the top circumference of the circular cylinder 2. A discharge port 31 is arranged on the bottom of the conical cylinder 3. An annular bracket 4 is arranged on the outer circumference of the bottom of the circular cylinder 2. A power mechanism 5 that moves in a circle around the central axis of the circular cylinder 2 is arranged on the annular bracket 4. A rotating part 6 is arranged on the inner side wall of the bottom of the circular cylinder 2. The rotating part 6 is used to make circular motion around the central axis of the circular cylinder 2, an electromagnetic suction component 7 is arranged between the rotating part 6 and the power mechanism 5, and the electromagnetic suction component 7 is used for the moving power mechanism 5 to drive the rotating part 6, a filtering counterweight part 8 is movably arranged at the inner bottom of the conical cylinder 3, and the filtering counterweight part 8 is provided with filtering holes and cannot fall downward from the discharge port 31, a scraper strip 9 is arranged between the rotating part 6 and the filtering counterweight part 8, and the scraper strip 9 is used to contact and clean the inner circumferential inclined wall of the conical cylinder 3, wherein the two ends of the scraper strip 9 extend to the top edge and the bottom edge of the inner circumferential inclined wall of the conical cylinder 3 respectively.

[0042] In order to conveniently demonstrate the core structure and concept principle of the present application, various components inside the sedimentation tank (such as a stirring structure, etc.) are shown in FIG. Figure 1 Not shown in the.

[0043] The beneficial technical effects of the ferrous sedimentation tank of the embodiment of the present application are roughly as follows:

[0044] When there is a lot of sediment attached to the inner circumferential inclined wall of the conical cylinder, the power mechanism 5 is started. Under the action of the electromagnetic suction component 7, the rotating part 6 inside the sedimentation tank can be driven to rotate around the central axis of the circular cylinder 2 in a non-contact manner. Combined with the counterweight effect of the filtering counterweight part 8, the scraper strip 9 can be driven to automatically scrape and clean along the inner circumferential inclined wall of the conical cylinder. There is no need for staff to enter the sedimentation tank for cleaning, which saves time and effort and has higher safety.

[0045] In this embodiment, the electromagnetic suction component 7 includes a stainless steel sheet 71 and an electromagnet sheet 72. Both the electromagnet sheet 72 and the stainless steel sheet 71 are in arc shape. The inner wall of the electromagnet sheet 72 is attached to the outer peripheral side wall of the circular cylinder 2, and the outer wall of the stainless steel sheet 71 is attached to the inner peripheral side wall of the circular cylinder 2. After the electromagnet sheet 72 is powered on, it is used to magnetically fix the stainless steel sheet 71.

[0046] The electromagnetic suction component 7 designed as above has a simple structure and is easy to install. The stainless steel sheet 71 contacts the chemical solution inside the sedimentation tank and is not easily corroded. At the same time, after the electromagnet sheet 72 is started, the magnetic suction fixing effect on the stainless steel sheet 71 is good, and the rotating part 6 can be smoothly driven to rotate. The electromagnet sheet 72 located outside the sedimentation tank does not contact the chemical solution inside the sedimentation tank, and it is convenient for later maintenance and replacement.

[0047] In this embodiment, the power mechanism 5 includes a motion mounting plate 51, a servo motor 52, a main shaft 53, a driving gear 54 and a ring gear 55. The electromagnet sheet 72 is fixed to the inner side of the motion mounting plate 51, the ring gear 55 is fixed to the outer peripheral side wall of the circular cylinder 2 and the two are arranged with the same central axis. The main shaft 53 is rotatably assembled between the motion mounting plate 51 and the annular bracket 4, and the rotating shaft axis of the main shaft 53 is arranged vertically. The driving gear 54 is fixed on the main shaft 53, and the driving gear 54 and the ring gear 55 are meshed for transmission. The servo motor 52 is installed on the motion mounting plate 51, and the output shaft of the servo motor 52 is connected to the main shaft 53.

[0048] After the servo motor 52 is started, it can drive the main shaft 53 to rotate. Since the driving gear 54 and the ring gear 55 are meshed and transmitted, the moving mounting plate 51, the servo motor 52, the main shaft 53, and the driving gear 54 themselves will rotate around the ring gear 55. The power mechanism 5 designed above has a simple structure and a low manufacturing cost. It is convenient to operate and install and has a more stable operation.

[0049] Because both the servo motor 52 and the electromagnet sheet 72 need power supply, and external power supply requires the use of longer wires, based on the fact that the servo motor 52 and the electromagnet sheet 72 are in a rotating and moving state when working, in order to prevent the problems of the wires being too long and easy to be entangled, the power mechanism 5 also includes a power supply battery 56, and the power supply battery 56 is installed on the motion mounting plate 51. The power supply battery 56 is electrically connected to the servo motor 52 and the electromagnetic suction component 7. The power supply battery 56 is used to provide electrical energy. Because the power supply battery 56 will move with the servo motor 52 and the electromagnet sheet 72, there is no need to use very long wires, which is safer.

[0050] In this embodiment, the annular bracket 4 includes an annular bottom plate 41 and an annular side plate 42, the inner side wall of the annular bottom plate 41 is connected to the outer peripheral side wall of the circular cylinder 2, the annular side plate 42 is vertically connected to the side of the annular bottom plate 41 away from the circular cylinder 2, and the top of the annular side plate 42 is supported on the bottom of the motion mounting plate 51. The annular bracket 4 designed as above has a simple and stable structure, and also has a certain safety protection effect on the servo motor 52, the main shaft 53 and the driving gear 54 inside it, which is safer.

[0051] In order to make the motion mounting plate 51 and the main shaft 53 more stable during rotation and reduce the resistance of sliding friction, a first annular groove 421 is arranged on the top of the annular side plate 42, and a freely rotatable ball 511 is embedded in the bottom of the motion mounting plate 51, and the bottom of the ball 511 slides in the first annular groove 421; a second annular groove 411 is arranged on the upper surface of the annular bottom plate 41, and the bottom of the main shaft 53 is a spherical end 531, and the spherical end 531 slides in the second annular groove 411. Through the above scheme, the power mechanism 5 can have smaller resistance during rotation, save energy and electricity, and can work and run for a longer time when the power of the power supply battery 56 is limited.

[0052] In this embodiment, the filter counterweight 8 includes a stainless steel hollow hollow ball 81 and a first clamping plate seat 82. The stainless steel hollow hollow ball 81 is placed on the inner bottom of the conical cylinder 3, and the first clamping plate seat 82 is connected to one side of the stainless steel hollow hollow ball 81. The first clamping plate seat 82 and the scraper bar 9 are detachably assembled through multiple groups of bolts. The filter counterweight 8 designed as above can not only ensure that the material can flow out smoothly from the discharge port 31, but also has a heavier weight and structural strength, so that the scraper bar 9 can be pulled to the auxiliary scraper bar 9 to complete a more thorough cleaning work. Moreover, based on the structural shape of the conical cylinder 3 itself, the stainless steel hollow hollow ball 81 only needs to be put in, and it can automatically slide to the inner bottom of the conical cylinder 3 and maintain a rolling state with maximum freedom. It is not easy to be easily blocked due to fixed position. The structure is ingenious and practical.

[0053] In this embodiment, the rotating part 6 includes a rotating body 61, a rolling ball 62, a sliding assembly 63 and a second clamping plate seat 64. The rolling ball 62 is embedded in the side of the rotating body 61 and can rotate freely. A part of the rolling ball 62 rolls along the inner side of the connection between the circular cylinder 2 and the conical cylinder 3. The second clamping plate seat 64 is arranged at the bottom of the rotating body 61. The second clamping plate seat 64 and the scraper strip 9 are detachably assembled by multiple sets of bolt groups. The sliding assembly 63 is arranged between the rotating body 61 and the inner wall of the bottom of the circular cylinder 2.

[0054] The sliding assembly 63 includes an annular slide rail 631 and an arc-shaped slider 632 . The annular slide rail 631 is fixed to the inner circumferential side wall of the circular cylinder 2 and the two are arranged with the same central axis. The arc-shaped slider 632 is fixed to one side of the rotating body 61 , and the arc-shaped slider 632 is slidably assembled on the annular slide rail 631 .

[0055] The structural design of the sliding assembly 63 and the rolling ball 62 can ensure that the trajectory of the rotating part 6 is more stable during rotation, and can reduce the resistance of the sliding friction of the rotating body 61. The power source of the rotating part 6 is the power supply battery 56, so the rotating part 6 of the above structure is energy-saving and power-saving, and can work for a longer time when the power of the power supply battery 56 is limited.

[0056] Reference Figure 1 and Figure 3 In order to make the scraper strip 9 more durable, the scraper strip 9 is made of rubber, and the cross-section of the scraper strip 9 is triangular. One of the side surfaces of the scraper strip 9 (specifically, it fits) is fitted to the inner circumferential inclined wall of the conical cylinder 3, and the above-mentioned side surface is specifically an arc-shaped surface that fits the inner circumferential inclined wall of the conical cylinder 3, and then the other two side surfaces of the scraper strip 9 (isosceles symmetrical) are arranged obliquely relative to the inner circumferential inclined wall of the conical cylinder 3, which has a certain shoveling effect, so that the scraper strip 9 can scrape off the sediment attached to the inner circumferential inclined wall of the conical cylinder 3 more thoroughly, and the cleaning effect is better.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
