Description

Technical Field

[0001] This utility model relates to the field of iron oxide red seed production technology, and in particular to a water washing equipment for iron oxide red seed production in the sulfuric acid process. Background Technology

[0002] In the sulfuric acid process for producing iron oxide red, the quality of the seed crystals plays a crucial role in the quality of the final product. Seed crystals often contain some impurities, such as unreacted sulfuric acid and iron salts. If these impurities are not removed, they will affect the color, purity, and dispersibility of iron oxide red. Therefore, an effective water washing device is needed to clean the seed crystals in order to improve their quality.

[0003] Existing iron oxide red seed washing devices typically consist of a washing tank, a stirrer, a filter, and inlet / outlet pipes. The washing tank holds the seed crystals and cleaning solution. The stirrer is usually installed at the top of the washing tank and is driven by a motor to rotate, stirring the seed crystals and cleaning solution in the tank and mixing them. The filter is a screen fixed to the bottom or side of the washing tank, used to separate the washed seed crystals from the cleaning solution. The inlet / outlet pipes are responsible for the injection and discharge of the cleaning solution, respectively. In use, the iron oxide red seed crystals are first placed in the washing tank, and then an appropriate amount of cleaning solution is injected through the inlet pipe. The stirrer is started to ensure that the seed crystals and cleaning solution are fully mixed. After a period of time, stirring is stopped, and the seed crystals are separated from the cleaning solution through the filter. Finally, the cleaning solution is discharged through the outlet pipe, completing the washing process. However, due to the design of the blades and the stirring method, the seed crystals and cleaning solution are difficult to mix fully in the edge and bottom areas of the washing tank, resulting in uneven washing.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 3 , Figure 4 and Figure 6This utility model provides an embodiment of a water washing device for iron oxide red seed crystals in the sulfuric acid process. It includes a washing tank 1, providing space for washing the iron oxide red seed crystals. An agitator 2 is installed inside the washing tank 1 to agitate the cleaning solution and seed crystals, ensuring thorough mixing and improving the cleaning effect. A cover plate 4 is rotatably connected to the top of the washing tank 1, sealing it to prevent splashing of the cleaning solution and the entry of external impurities. Connecting pipes 5 are connected to the top left side of the cover plate 4 for adding iron oxide red seed crystals and injecting the cleaning solution into the washing tank 1. A discharge pipe 6 is fixedly connected to the left side of the outer wall of the washing tank 1 for discharging the cleaned seed crystals. An on / off component 7 is installed at the top of the discharge pipe 6 to control the discharge. The on / off state of 6 allows for the on-demand discharge of seed crystals. A support assembly 8 is installed at the bottom of the washing tank 1 to support the entire washing equipment and ensure its stability. A conveying pipe 9 is connected to the bottom of the washing tank 1 to discharge the cleaning liquid within it. A filter mechanism 3 is installed at the left end of the conveying pipe 9. The stirring mechanism 2 includes a fixed plate 201, providing a mounting and support base for rotating rods 202 and 203. The fixed plate 201 is fixedly connected to the top of the inner wall of the washing tank 1. Rotating rod 202 is rotatably connected to the middle of the inner wall of the fixed plate 201. Rotating rods 203 are rotatably connected to both the left and right sides of the inner wall of the fixed plate 201, working in conjunction with rotating rod 202. The rotating rod 202 and the two rotating rods 203 are both fixedly connected to the upper and lower sides of their outer walls by stirring blades 204. When rotating, these blades agitate the cleaning fluid, promoting contact between the cleaning fluid and the seed crystals. Multiple turbulence holes 205 are formed on the outer walls of the stirring blades 204 to further disrupt the flow path of the cleaning fluid and enhance the cleaning effect. The top of the rotating rod 202 passes through the fixing plate 201 and is fixedly connected to a gear 207, which meshes with gear 206 to transmit and distribute power. The tops of the two rotating rods 203 also pass through the fixing plate 201 and are fixedly connected to gears 206. These gears mesh with gears 207, allowing the rotating rods 203 to move in tandem with the crystals. The rotating rod 202 rotates synchronously with the water washing tank 1. A motor 208 is fixedly connected to the bottom of the water washing tank 1 to provide rotational power for the rotating rod 202. The output end of the motor 208 is fixedly connected to the bottom end of the rotating rod 202. A spiral baffle 210 is fixedly connected to the inner wall of the water washing tank 1 to further disrupt the flow of the cleaning liquid, so that the cleaning liquid forms a more complex flow field in the water washing tank 1 and improves the uniformity of cleaning. A separation component 209 is provided inside the water washing tank 1. The separation component 209 includes a filter inclined plate 2091, which is used to intercept the seed crystals and guide their flow direction. The outer wall of the filter inclined plate 2091 is fixedly connected to the bottom of the inner wall of the water washing tank 1. Multiple filter holes 2092 are opened on the top left side of the outer wall of the filter inclined plate 2091.Used to filter the cleaning liquid, allowing the cleaning liquid to pass through while intercepting the seed crystals, the bottom of the inner wall of the washing tank 1 is fixedly connected to a motor 2 10, which provides rotational power to the cam 11. The output end of the motor 2 10 is fixedly connected to the cam 11, which strikes the filter inclined plate 2091 to prevent the filter hole 2092 from being blocked, thus ensuring the smooth separation of the seed crystals.

[0033] Specifically, the washing tank 1 is the main space of the entire washing process, providing a place for the seed crystals and cleaning solution to mix. The fixing plate 201 in the stirring mechanism 2 is fixed to the top of the inner wall of the washing tank 1, providing support for the rotating rods 202 and 203. The rotating rods 202 and 203 are connected by the meshing of gears 206 and 207. When the bottom motor 208 drives the rotating rod 202 to rotate, they rotate synchronously, which in turn drives the stirring blades 204 fixed to their outer walls to rotate. The stirring blades 204 disrupt the flow of the cleaning solution, promoting full contact between the seed crystals and the cleaning solution. The turbulence holes 205 and the spiral turbulence plates 210 further disrupt the path of the cleaning solution, enhancing the cleaning effect and allowing the seed crystals at the edge of the washing tank 1 to move towards the center for cleaning. The cover plate 4 is rotatably connected to the top of the washing tank 1, serving a protective and sealing function. The connecting pipe 5 connects to the top of the cover plate 4. On the left side of the unit, seed crystals are added and cleaning solution is injected. The discharge pipe 6 is fixed to the left side of the outer wall of the washing tank 1 to discharge the cleaned seed crystals. The on / off component 7 at the top controls the timing of seed crystal discharge. The support component 8 is located at the bottom of the washing tank 1 to support the entire equipment. The conveying pipe 9 is connected to the bottom of the washing tank 1 to discharge the cleaning solution. The filter inclined plate 2091 of the separation component 209 is fixed to the bottom of the inner wall of the washing tank 1. It intercepts the cleaned seed crystals through the filter holes 2092 and uses the inclined structure to make the seed crystals move to the left. The motor 10 is fixed to the bottom of the inner wall of the washing tank 1. The cam 11 connected to its output end strikes the filter inclined plate 2091 to prevent the filter holes 2092 from being blocked and to ensure smooth separation of the seed crystals. Each component performs its own function and cooperates with each other, effectively solving the problems of uneven mixing and cleaning of seed crystals and cleaning solution in the prior art, and realizing a highly efficient iron oxide red seed crystal washing process.

[0034] Reference Figure 1 , Figure 2 and Figure 5The filtration mechanism 3 includes a filter box 301, which provides space for filtering the cleaning fluid. The right side of the filter box 301 is connected to the left end of the delivery pipe 9. A filter frame 302 is slidably connected to the inner wall of the filter box 301, allowing it to slide within the filter box 301 for easy disassembly and replacement to meet different filtration needs or for cleaning and maintenance of the filter components. A filter screen 303 is fixedly connected to the top of the inner wall of the filter frame 302, which initially filters the cleaning fluid and intercepts larger impurities. A filter plate 304 is fixedly connected to the bottom of the filter screen 303, further filtering out particles smaller than those intercepted by the filter screen 303, thus improving the cleanliness of the cleaning fluid. Filter cotton 305 is fixedly connected to the bottom of the filter plate 304, which performs final fine filtration of the cleaning fluid through its dense fiber structure. A sealing cover 306 is rotatably connected to the top of the filter box 301, allowing the filter box 301 to be opened or closed to prevent external impurities from entering. A filter box 301 is provided with a recovery component 307 at its rear side for recovering the filtered cleaning liquid and realizing the recycling of the cleaning liquid. The recovery component 307 includes a water tank 3071, the front side of the outer wall of the water tank 3071 is fixedly connected to the rear side of the outer wall of the filter box 301, and a water pump 3072 is fixedly connected to the left side of the outer wall of the water tank 3071. The front end of the water pump 3072 is connected to an extraction pipe 3073, the front end of which is connected to the bottom left side of the filter box 301 for extracting the filtered cleaning liquid from the filter box 301. The top of the water pump 3072 is connected to a water supply pipe 3074 to transport the cleaning liquid extracted by the water pump 3072 to the water tank 3071. The top end of the water supply pipe 3074 is connected to the water tank 3071. The left side of the outer wall of the water tank 3071 is connected to a drain pipe 3075 to discharge the cleaning liquid stored in the water tank 3071, thus realizing the recycling of the cleaning liquid.

[0035] Specifically, the components of the filtration mechanism 3 and the recovery assembly 307 work together. The right side of the filter box 301 is connected to the left end of the support assembly 8, receiving the cleaning liquid containing impurities discharged from the washing tank 1 through the conveying pipe 9. The filter frame 302 slides on the inner wall of the filter box 301 for easy disassembly and cleaning. The filter screen 303 is fixed to the top of the inner wall of the filter frame 302, filtering out larger impurities first to reduce the burden on subsequent filtration. The filter plate 304 below it further filters out smaller impurities. The filter cotton 305 is at the bottom of the filter plate 304, completing the final fine filtration to ensure the cleanliness of the cleaning liquid. The sealing cover 306 is rotatably connected to the top of the filter box 301 to prevent external impurities. The system ensures a stable filtration environment. The recovery component 307 is fixed to the rear side of the outer wall of the filter box 301. The water tank 3071 is used to store the filtered cleaning solution. The water pump 3072 is fixed to the left side of the outer wall of the water tank 3071. The filtered cleaning solution is drawn from the bottom left side of the filter box 301 through the extraction pipe 3073 and transported to the water tank 3071 through the water supply pipe 3074 for recycling. The drain pipe 3075 connected to the left side of the outer wall of the water tank 3071 allows the cleaning solution in the water tank 3071 to be extracted and reused for washing when needed through an external pipeline. The cooperation of these components realizes the filtration, recovery and recycling of the cleaning solution, improving resource utilization.

[0036] Reference Figure 1 , Figure 2 and Figure 3The on / off assembly 7 includes a baffle 701 for controlling the opening and closing of the discharge pipe 6, thereby controlling the discharge of seed crystals. The outer wall of the baffle 701 is slidably connected to the middle of the inner wall of the discharge pipe 6, allowing it to move flexibly within the discharge pipe 6 to open or close it. The top of the outer wall of the baffle 701 penetrates the discharge pipe 6 and is fixedly connected to a connecting plate 702, facilitating operation of the baffle 701 by external force and providing a force point for its movement. A fixing plate 703 is fixedly connected to the left side of the outer wall of the washing tank 1, serving as a sliding rod 7. 04 and spring 705 provide the mounting base. A sliding rod 704 is slidably connected to the middle of the inner wall of the second fixing plate 703, which can slide within the second fixing plate 703 and cooperate with the connecting plate 702 to realize the lifting control of the baffle 701. Multiple springs 705 are fixedly connected to the bottom of the second fixing plate 703 to provide the reset power for the baffle 701, keeping the baffle 701 in a closed state of the discharge pipe 6 when no external force is applied. The bottom ends of the multiple springs 705 are fixedly connected to the connecting plate 702; the right side of the outer wall of the cover plate 4 is fixed. The cover plate 4 is connected to the washing tank 1 by hooks 12, which engage with latches 13 to connect and fix the cover plate 4 to the washing tank 1. Two latches 13 are fixedly connected to the top right side of the outer wall of the washing tank 1. The latches 13 and hooks 12 engage with each other, so that the cover plate 4 can be firmly closed on the top of the washing tank 1 to prevent the cleaning liquid from splashing out and the external impurities from entering. The two latches 13 engage with the corresponding hooks 12. The support assembly 8 includes multiple fixing seats 801 for connecting the washing tank 1 to the support legs 802 to distribute the weight of the washing tank 1. The outer walls of multiple fixed seats 801 are fixedly connected to the bottom of the washing tank 1 around the perimeter. Support legs 802 are fixedly connected to the bottom of each fixed seat 801 to support the entire washing equipment, keeping the washing tank 1 at a certain distance from the ground and enhancing the stability of the equipment. Positioning plates 803 are fixedly connected to the bottom of each support leg 802. Bolts 804 are threaded at the four corners of the outer walls of each positioning plate 803, which can be screwed into the ground or other supporting surfaces to firmly fix the equipment in the designated position.

[0037] Specifically, baffle 701 is slidably connected to the middle of the inner wall of discharge pipe 6 to control the opening and closing of discharge pipe 6. Connecting plate 702 connected to the top of baffle 701 can drive baffle 701 to move by external force. Fixing plate 703 is fixed to the left side of the outer wall of washing tank 1, providing a sliding track for sliding rod 704. Sliding rod 704 is connected to connecting plate 702 by spring 705. When sliding rod 704 is pulled upward, it overcomes the elastic force of spring 705, causing connecting plate 702 and baffle 701 to move upward, opening discharge pipe 6 and allowing seed crystals to be discharged. When sliding rod 704 is released, spring 705 returns to its original position, pushing baffle 701 to close the discharge. The hook 12 on the right side of the cover plate 4 engages with the buckle 13 on the top right side of the washing tank 1, so that the cover plate 4 can be securely closed on the top of the washing tank 1, preventing the cleaning liquid from splashing out and the entry of external debris, while also making it convenient to open the cover plate 4 for operation. In the support assembly 8, multiple fixing seats 801 are fixed around the bottom of the washing tank 1 to provide support for the washing tank 1. The support legs 802 connected to the bottom of the fixing seats 801 enhance stability. The positioning plate 803 at the bottom of the support leg 802 increases the contact area with the ground. The bolts 804 with threads at the four corners of the positioning plate 803 can adjust the height of the equipment and fix the position of the equipment to ensure the stability of the washing process.

[0038] Working Principle: First, the red seed crystal is placed into the washing tank 1 through the connecting pipe 5. Then, cleaning fluid is injected through the connecting pipe 5. Motor 208 drives rotating rod 202 to rotate. During the rotation of rotating rod 202, it drives gear 207, which is fixedly connected to it, to rotate. Since gear 207 meshes with two gears 206, the rotation of gear 207 drives the two gears 206 to rotate. When gears 206 rotate, they in turn drive the two rotating rods 203, which are fixedly connected to them, to rotate synchronously. Ultimately, rotating rod 202 and the two rotating rods 203 rotate simultaneously. During the rotation of rotating rod 202 and the two rotating rods 203, multiple stirring blades 204 fixedly connected to their upper and lower outer walls rotate accordingly. The rotation of the stirring blades 204 disrupts the flow of the cleaning fluid, promoting full contact between the cleaning fluid and the seed crystal for cleaning. Simultaneously, the stirring... The turbulence holes 205 on the outer wall of leaf 204 and the spiral turbulence plates 210 fixedly connected to the inner wall of the washing tank 1 further disrupt the flow path of the cleaning liquid. After cleaning, the cleaning liquid is discharged from the conveying pipe 9 connected to the bottom of the washing tank 1. During the discharge process, the separation component 209 plays a role. Multiple filter holes 2092 on its filter inclined plate 2091 intercept the cleaned crystal seeds. Since the filter inclined plate 2091 is tilted to the left, the crystal seeds will move to the left. When it is necessary to remove the crystal seeds, pull the sliding rod 704 upward. The sliding rod 704 drives the connecting plate 702 and the baffle 701 to move upward, squeezing the spring 705. At this time, the crystal seeds can be removed from the discharge pipe 6. After releasing the sliding rod 704, the connecting plate 702 is pushed downward under the action of the spring 705, so that the bottom of the baffle 701 is in contact with the bottom of the inner wall of the discharge pipe 6, which plays a sealing role and prevents the crystal seeds or liquid from leaking at will.

[0039] The cleaning fluid containing impurities discharged through the delivery pipe 9 directly enters the filter box 301, which is connected to the left end of the support assembly 8. Upon entering the filter box 301, the cleaning fluid first comes into contact with the filter screen 303 fixed to the top of the inner wall of the filter frame 302. The filter screen 303 has large mesh openings, its main function being to intercept larger impurities in the cleaning fluid. Larger particles or lumps are blocked by the filter screen 303 and cannot continue flowing with the cleaning fluid. The cleaning fluid, after initial filtration by the filter screen 303, continues to flow downwards to the filter plate 304 fixedly connected to the bottom of the filter screen 303. The filter plate 304 has relatively small pores, capable of filtering out particles smaller than those intercepted by the filter screen 303, further purifying the cleaning fluid. The cleaning solution filtered by filter plate 304 continues to flow downwards to filter cotton 305 fixed at the bottom of filter plate 304. Filter cotton 305 has a dense fiber structure, which can complete the final filtration, adsorbing or blocking the tiny impurities and suspended matter remaining in the cleaning solution, making the cleaning solution after these three layers of filtration relatively clean, and finally flowing into the bottom of filter box 301. At this time, water pump 3072 located on the left side of the outer wall of water tank 3071 starts to work. Water pump 3072 generates suction and draws in the filtered cleaning solution at the bottom of filter box 301 through the extraction pipe 3073 connected at the front end. The cleaning solution is transported to water tank 3071 for storage through water pipe 3074 connected at the top of water pump 3072, realizing the recycling of cleaning solution.
