Description

Technical Field

[0001] This utility model relates to the field of iron oxide yellow production technology, and in particular to a discharge device for producing low-sulfur iron oxide yellow. Background Technology

[0002] Iron oxide yellow is an inorganic pigment, appearing as a lemon yellow to brown powder. It is insoluble in water, light-resistant, weather-resistant, and heat-resistant, and has a wide range of functions. It is used as a colorant in the fields of construction and coatings, and can also be used as a fertilizer colorant to distinguish different types of fertilizers for precise fertilization. It can also adsorb heavy metals to purify the environment, meeting the needs of ecological planting.

[0003] The discharge device for producing low-sulfur iron oxide yellow is a crucial piece of equipment in the iron oxide yellow production process. It is mainly used to accurately and stably transport the iron oxide yellow material generated by the reaction from the storage container to the subsequent processing steps, ensuring that the material can meet the requirements of different processes for material flow and precision during the transportation process.

[0004] Early feeding devices for producing low-sulfur iron oxide yellow consisted of a storage tank, a manual valve, and a conveying pipeline. The storage tank held the reacted iron oxide yellow material, and the manual valve, installed at the tank's outlet, controlled the discharge manually. The conveying pipeline transported the material to the next process. Because the manual valve struggled to precisely control the flow rate, it easily resulted in over- or under-discharge when dealing with high-viscosity iron oxide yellow slurry. To address this, existing feeding devices employed electric regulating valves. These valves, controlled by an automated control system, precisely adjusted the valve opening based on production needs to control the material flow. However, in practical applications, the electric regulating valves could not accurately determine the specific amount of material discharged, failing to achieve precise quantitative dispensing, ensuring product consistency, and impacting product quality, thus failing to meet user requirements. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a feeding device for producing low-sulfur iron oxide yellow, which aims to improve the problem that the existing technology cannot achieve precise quantitative feeding.

[0012] As a further description of the above technical solution:

[0013] The steering assembly includes a load-bearing column, which is rotatably connected to the bottom of a load-bearing plate. A base plate is fixedly connected to the bottom of the load-bearing column. A fixed column one is fixedly connected to the top right side of the base plate. A rotating block one is rotatably connected to the top of the fixed column one. A cylinder two is fixedly connected to the rear end of the rotating block one. A rotating block two is fixedly connected to the output end of the cylinder two. A fixed column two is rotatably connected to the top of the rotating block two. The top end of the fixed column two is fixedly connected to the bottom right side of the load-bearing plate.

[0014] As a further description of the above technical solution:

[0015] The cleaning assembly includes two slide rods. The adjacent sides of the two slide rods are fixedly connected to the left and right sides of the outer wall of the rotating shaft, respectively.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, after the counterweight is moved to the desired weight position by the slider, the material in the holding shell increases. When the weights at both ends are equal, the trigger switch is activated to close the electric valve, and cylinder two is activated, causing the balance bar to rotate 90 degrees. Then, cylinder one is activated to push the moving block to slide. Through the displacement of the moving block, the opening and closing plate moves to both sides of the holding shell, and the material inside the holding shell falls downward, thereby realizing the quantitative feeding process and meeting the user's needs.

[0024] In this invention, the output end of the motor drives the rotating shaft to rotate, which causes the stirring blades on both sides to stir and loosen the material. The bottom auger blade can stably discharge the material through the discharge pipe, avoiding blockage of the pipe. At the same time, the scrapers on both sides rotate with the rotating shaft and, together with the auger blade, clean the inner wall of the storage tank and the discharge pipe. When the material on the tank wall is difficult to clean, the spring elastically resets the scraper, preventing the rigid connection from damaging the scraper. Attached Figure Description

[0033] 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.

[0034] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a feeding device for producing low-sulfur iron oxide yellow, comprising a support frame 1, a weighing mechanism 2 disposed on the inner side of the support frame 1, a pad 3 disposed at the bottom of the support frame 1, and multiple support legs 4 fixedly connected to the top left side of the pad 3. The support legs 4 are used to support and ensure the stability of the storage tank 5. The tops of the multiple support legs 4 are fixedly connected to the same storage tank 5, which is used to store materials. An anti-blocking mechanism 6 is disposed inside the storage tank 5. The weighing mechanism 2 includes a fulcrum rod 201, which is fixedly connected to the middle of the inner side of the support frame 1. A balance rod 202 is rotatably connected to the outer wall of the fulcrum rod 201. The fulcrum rod 201 is used to provide a fulcrum for the balance rod 202. A chute 203 is provided at the front right side. A slider 204 is slidably connected to the inner side of the chute 203. A counterweight 205 is rotatably connected to the bottom of the slider 204. By moving the counterweight 205, a quantitative amount is measured. A material holding shell 206 is fixedly connected to the left end of the balance bar 202. The material holding shell 206 is used to hold a quantitative amount of material. A trigger switch 207 is fixedly connected to the inner left end of the support frame 1. The material discharge is controlled by the trigger switch 207. An opening and closing component 208 is provided at the bottom of the material holding shell 206. A load-bearing plate 209 is fixedly connected to the bottom of the support frame 1. A steering component 210 is provided at the bottom of the load-bearing plate 209. The opening and closing component 208 includes a cylinder 2081, which is fixedly connected to the bottom left side of the balance bar 202. On one side, a movable block 2082 is fixedly connected to the output end of cylinder 2081. Cylinder 2081 can push and pull the movable block 2082. Linkage rods 2083 are rotatably connected to the front and rear sides of the movable block 2082. The movement of the movable block 2082 drives the linkage rods 2083 to rotate. Opening and closing plates 2084 are rotatably connected to the other ends of the two linkage rods 2083. The opening and closing plates 2084 control the discharge of the metered material. Guide grooves 2085 are provided on the left and right sides of the bottom of the material container 206. The guide grooves 2085 provide guidance and fixation for the opening and closing plates 2084. The top left and right sides of the two opening and closing plates 2084 are slidably connected to the inner sides of the corresponding guide grooves 2085. The steering assembly 210 includes a load-bearing column 2101. The load-bearing column 2101 is rotatably connected to the bottom of the load-bearing plate 209. The load-bearing column 2101 is used to provide support. The bottom of the load-bearing column 2101 is fixedly connected to the base plate 2102. The top right side of the base plate 2102 is fixedly connected to the first fixed column 2103. The top of the first fixed column 2103 is rotatably connected to the first rotating block 2104. The rear end of the first rotating block 2104 is fixedly connected to the second cylinder 2105. The output end of the second cylinder 2105 is fixedly connected to the second rotating block 2106. The top of the second rotating block 2106 is rotatably connected to the second fixed column 2107. The second cylinder 2105 pushes the second fixed column 2107 to rotate the load-bearing plate 209. The top of the second fixed column 2107 is fixedly connected to the bottom right side of the load-bearing plate 209.

[0035] Specifically, when the device needs to discharge a fixed amount of material, the counterweight 205 is first moved to the required weight position via the slider 204. The balance bar 202 then tilts according to the change in weight on both sides. Next, by opening the electric valve 607, the material in the storage tank 5 is discharged. The material is buffered by the inclined surface of the discharge pipe 606 and falls into the holding shell 206. As the amount of material in the holding shell 206 increases, the tilt angle of the balance bar 202 will change accordingly until the two ends reach a parallel state. As one end of the holding shell 206 gradually becomes heavier, the balance bar 202 gradually returns to balance. When the weights at both ends are equal, the pressure trigger switch 207 on the bottom left side of the balance bar 202 is activated. After the trigger switch 207 is activated, the transmission command causes the electric valve 607 to close, stopping the material transmission. At this time, the cylinder 2105 is activated, pushing the fixed column 2107 to move and rotating the block 21 The rotational connection between cylinder 206 and fixed column 2107 converts the linear motion of cylinder 2105 into the rotation of the load-bearing plate 209 around the bottom load-bearing column 2101 driven by fixed column 2107. As the load-bearing plate 209 rotates, cylinder 2105 and the rotating block also rotate slightly around fixed column 1 2103 until the output end of cylinder 2105 pushes the load-bearing plate 209 to rotate 90 degrees and stop. At this time, the weighing mechanism 2 rotates 90 degrees. Then, cylinder 1 2081 starts, pushing the moving block 2082 to slide, driving the linkage rods 2083 on both sides to rotate. Then, the linkage rods 2083 on both sides drive the opening and closing plate 2084 to move. The opening and closing plate 2084 is guided and limited by the guide groove 2085 to ensure that it moves to both sides of the material container 206, so that the material in the material container 206 falls downward, thereby completing the quantitative feeding process.

[0036] Reference Figure 1 , Figure 5 and Figure 6The anti-blocking mechanism 6 includes a motor 601, which is fixedly connected to the top of the storage tank 5. A discharge pipe 606 is connected to the bottom of the storage tank 5 for discharging materials. An electric valve 607 is installed on the right side of the outer wall of the discharge pipe 606, controlling the opening and closing of the discharge pipe 606. The output end of the motor 601 passes through the top of the storage tank 5 and is fixedly connected to a rotating shaft 602. A rotating rod 603 is fixedly connected to the bottom of the rotating shaft 602. Multiple stirring blades 604 are fixedly connected to the left and right sides of the outer wall of the rotating rod 603 for stirring the materials in the tank. An auger blade 605 is fixedly connected to the bottom of the outer wall of the rotating rod 603. Each component is equipped with a cleaning assembly 608, which includes two slide rods 6081. The adjacent sides of the two slide rods 6081 are fixedly connected to the left and right sides of the outer wall of the rotating shaft 602, respectively. Hollow rods 6082 are slidably connected to the opposite sides of the two slide rods 6081. Springs 6084 are fixedly connected to the inner side of the two hollow rods 6082. The slide rods 6081 and hollow rods 6082 can be reset by the springs 6084. The adjacent sides of the two springs 6084 are fixedly connected to one end of the corresponding slide rod 6081. Scrapers 6083 are fixedly connected to the opposite ends of the two hollow rods 6082. The scrapers 6083 scrape off the residual material on the inner wall of the storage tank 5.

[0037] Specifically, when material accumulates in the storage tank 5 and is discharged from the discharge pipe 606, it can cause pipe blockage. To solve this problem, the motor 601 can be started, and the rotational power of the output end of the motor 601 can drive the rotating shaft 602, which in turn causes the rotating rod 603 to rotate. The rotation of the rotating rod 603 drives the stirring blades 604 on both sides to effectively stir the material and loosen it, making it easier to discharge. Subsequently, the auger blades 605 at the bottom can stably discharge the material through the discharge pipe 606, preventing pipe blockage. At the same time, the scrapers 6083 on both sides rotate with the rotating shaft 602 and work together with the auger blades 605 to clean the inner walls of the storage tank 5 and the discharge pipe 606. When the material on the tank wall is difficult to clean, the sliding rod 6081 and the hollow rod 6082 cooperate with the elastic return of the spring 6084 to ensure that the scraper 6083 will not be damaged due to rigid connection.

[0038] Reference Figure 1 , Figure 5 and Figure 6The top left side of the storage tank 5 is connected to the feed pipe 7. The feed pipe 7 has grooves 8 on both the left and right sides. The same lifting rod 9 is slidably connected to the inner side of the two grooves 8. The lifting rod 9 can lift the filter screen 10 for easy cleaning. The bottom of the lifting rod 9 is fixedly connected to the filter screen 10. When feeding, the filter screen 10 filters impurities. The outer diameter of the auger blade 605 is the same as the inner diameter of the discharge pipe 606. The trigger switch 207 is electrically connected to the electric valve 607, cylinder 1 2081 and cylinder 2 2105. The bottom left side of the balance bar 202 has a limit groove 11. The top of the moving block 2082 is slidably connected to the inner side of the limit groove 11. The limit groove 11 is used to provide guidance for the moving block 2082.

[0039] Specifically, when the material enters the storage box through the feed pipe 7, it is filtered by the filter screen 10 to remove impurities. Subsequently, the impurities accumulate on the filter screen 10, and the filter screen 10 can be lifted out of the feed pipe 7 by the lifting rod 9 for cleaning. The auger blade 605 can clean the inner wall of the discharge pipe 606 while conveying the material to prevent blockage. The sequence of operation of the electric valve 607, cylinder 1 2081 and cylinder 2 2105 is controlled by the trigger switch 207.

[0040] Working principle: When the device needs to discharge a fixed amount of material, the counterweight 205 is first moved to the required weight position by the slider 204. The balance bar 202 tilts according to the weight on both sides. Then, the electric valve 607 is opened to discharge the material inside the storage tank 5. The material falls into the holding shell 206 through the inclined surface of the discharge pipe 606. As the material in the holding shell 206 increases, the tilt angle of the balance bar 202 also changes, gradually making the two ends parallel. When one end of the holding shell 206 gradually becomes heavier and the balance bar 202 gradually becomes balanced, the bottom left side of the balance bar 202 will trigger the trigger switch 207 through pressure. When the weights at both ends are the same, the trigger switch 207 is activated, transmitting a command to close the electric valve 607 to stop the material transmission. The cylinder 2105 is activated, and the cylinder 2105 pushes the fixed column 2107 to move through the output end. The rotating block 2106 and the fixed column 2107 are then moved. The rotational connection of cylinder 2105 converts the linear motion of cylinder 2105 into the rotation of the load-bearing plate 209 around the bottom load-bearing column 2101 by the fixed column 2107. As the load-bearing plate 209 rotates, it drives cylinder 2105 and the rotating block to rotate slightly around the fixed column 2103 until the output end of cylinder 2105 pushes the load-bearing plate 209 to rotate 90 degrees and stop. At this time, the weighing mechanism 2 rotates 90 degrees. Then, cylinder 2081 starts to push the moving block 2082 to slide. As the moving block 2082 slides, it drives the linkage rods 2083 on both sides to rotate. Then, the linkage rods 2083 on both sides drive the opening and closing plate 2084 to move. The opening and closing plate 2084 is guided and limited by the guide groove 2085, so that the opening and closing plate 2084 moves to both sides of the material holding shell 206, causing the material inside the material holding shell 206 to fall downward, thereby realizing the quantitative feeding process.

[0041] Furthermore, when materials accumulate in the storage tank 5 and are discharged from the discharge pipe 606, they may clog the pipe. At this time, by starting the motor 601, the output end of the motor 601 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the rotating rod 603 to rotate, so that the stirring blades 604 on both sides stir the materials, making the materials loose and no longer accumulate, making them easier to discharge. Subsequently, the bottom auger blade 605 can stably discharge the materials through the discharge pipe 606, avoiding pipe blockage. At the same time, the scrapers 6083 on both sides rotate with the rotating shaft 602, and together with the auger blades 605, they clean the inner walls of the storage tank 5 and the discharge pipe 606. When the materials on the tank wall are difficult to clean, the sliding of the sliding rod 6081 and the hollow rod 6082 and the elastic reset of the spring 6084 prevent the scraper 6083 from being damaged by rigid connection.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
