Description

Technical Field

[0001] The utility model belongs to the technical field of steel shot production and rust removal, and particularly relates to a rust removal device for steel shot production. Background Technique

[0002] In the process of steel shot production, rust removal is a key link. Traditional rust removal methods have many limitations, and pickling has gradually become an important option. With the continuous development of industry, the requirements for the quality of steel shot are increasing day by day. The existence of rust will seriously affect the performance and subsequent use of steel shot. Some rust removal means used in the past were either inefficient or ineffective and could not meet the needs of modern production. Pickling uses a specific acid solution to chemically react with the rust layer on the surface of steel shot and can relatively thoroughly remove rust. It has the advantages of good rust removal effect and high efficiency.

[0003] However, during the use of the existing rust removal device for steel shot production, with multiple pickling processes, some rust and impurities may adhere to the inner wall and gradually accumulate, affecting the subsequent pickling effect and the quality of steel shot. The substances accumulated on the inner wall may continuously mix into the pickling solution, resulting in a decrease in the purity of the pickling solution and a reduction in pickling efficiency and quality. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rust removal device for steel shot production. By setting an inner wall scraping mechanism, the problem that with multiple pickling processes, some rust and impurities may adhere to the inner wall and gradually accumulate, affecting the subsequent pickling effect and the quality of steel shot, and the substances accumulated on the inner wall may continuously mix into the pickling solution, resulting in a decrease in the purity of the pickling solution and a reduction in pickling efficiency and quality is solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a rust removal device for steel shot production, including a mixing tank, and an inner wall scraping mechanism and a stirring mechanism are arranged on the mixing tank;

[0007] A feeding funnel is communicated and arranged at the top of the mixing tank, a discharge cover plate is hinged on the front outer wall of the mixing tank, a plurality of support legs are fixedly connected to the outer wall of the mixing tank, a liquid outlet pipe with a valve is communicated and arranged at the bottom of the mixing tank, the inner wall scraping mechanism includes a scraping component and a buffer component, the scraping component includes a reciprocating lead screw one rotatably connected to the inner wall of the mixing tank, the bottom of the reciprocating lead screw one rotatably extends outside the mixing tank, a scraper is threadedly connected to the outer wall of the reciprocating lead screw one, and a slide bar one is fixedly connected to the inner wall of the mixing tank, and the slide bar one slidably penetrates through the scraper.

[0008] Furthermore, the buffer assembly includes a plurality of grooves formed in the bottom of the scraper, and dampers are fixedly connected to the inner walls of the tops of the plurality of grooves.

[0009] Furthermore, springs are sleeved on the outer walls of the plurality of dampers, the tops of the plurality of springs are fixedly connected to the scraper, buffer blocks are fixedly connected to the bottoms of the plurality of dampers, and the bottoms of the plurality of springs are fixedly connected to the buffer blocks.

[0010] Furthermore, the stirring mechanism includes a driving assembly and a lifting and stirring assembly. The driving assembly includes a rotating shaft rotatably connected to the inner wall of the stirring tank, the bottom of the rotating shaft extends rotatably outside the stirring tank, and a motor is fixedly connected to the extending portion on the bottom side of the rotating shaft.

[0011] Furthermore, a motor sleeve is fixedly connected to the outer wall of the motor, the top of the motor sleeve is fixedly connected to the stirring tank, and a plurality of stirring blocks are fixedly connected to the outer wall of the rotating shaft.

[0012] Furthermore, pulley wheels are fixedly connected to the extending portions on the bottom sides of the rotating shaft and the first reciprocating lead screw, and a belt is sleeved on the two pulley wheels.

[0013] Furthermore, the lifting and stirring assembly includes a fixing piece fixedly connected to the outer wall of the rotating shaft, a second reciprocating lead screw is fixedly connected to the inner wall of the top of the stirring tank, and the outer wall of the rotating shaft is rotatably connected to the second reciprocating lead screw.

[0014] Furthermore, a lifting block is threadedly connected to the outer wall of the second reciprocating lead screw, two sliding rods two are fixedly connected to the top of the fixing piece, the tops of the two sliding rods two slidably penetrate through the outer wall of the lifting block and extend to the outside, and two stirring rods are fixedly connected to the outer wall of the lifting block.

[0015] The utility model has the following beneficial effects:

[0016] By setting up an inner wall scraping mechanism, when the rotating shaft rotates, the rotating shaft will drive the reciprocating lead screw one to rotate through the pulley and belt, so that the scraper on the sliding rod one rises and falls to scrape the inner wall of the mixing tank. Since the density of steel sand is much greater than that of water, even if the part at the bottom is stirred, a small part of the steel sand will stay at the bottom of the device. When the scraper descends to below the device, the buffer block will first touch the steel sand, and the pressure exerted on the buffer block when the scraper continues to press down will be buffered by the groove and the damper. Moreover, the bottom of the buffer block is designed in an arc shape, which greatly reduces the damage to the mixing tank caused by the extrusion between the inner wall scraping mechanism and the steel sand during scraping, enabling the effective removal of steel sand, rust, and other impurity residues attached to the inner wall, avoiding the adverse effects of these residues on the subsequent pickling process, reducing the entry of inner wall attachments into the acid solution, maintaining the good chemical properties of the acid solution, ensuring the stability and consistency of the rust removal effect, preventing blockage caused by the continuous accumulation of attachments in certain parts, ensuring the normal flow of the fluid in the device, and maintaining the smooth progress of the pickling operation;

[0017] By setting up a stirring mechanism, after the steel sand and the pickling solution are poured into the device, the motor can be started. The motor drives the stirring block to rotate through the rotating shaft, stirring up the steel sand located below to avoid its accumulation caused by sinking to the bottom. At this time, the rotating shaft will also drive the lifting block on the sliding rod two to rise and fall on the reciprocating lead screw two while stirring the steel sand in the mixing tank, which can ensure that the acid solution can contact the steel sand evenly, avoid too high or too low local acid solution concentration, make the rust removal process more uniform and comprehensive, accelerate the chemical reaction speed between the rust on the surface of the steel sand and the acid solution through stirring, improve the rust removal efficiency, and prevent the components in the acid solution from precipitating or stratifying, maintaining the consistency of the acid solution performance.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 As shown, the present utility model is a rust removal device for steel shot production, including a stirring tank 1, and an inner wall scraping mechanism 2 and a stirring mechanism 3 are arranged on the stirring tank 1;

[0029] A feeding funnel 101 is connected and communicated at the top of the stirring tank 1, a discharge cover plate 102 is hinged on the front outer wall of the stirring tank 1, several support legs 103 are fixedly connected to the outer wall of the stirring tank 1, and a liquid outlet pipe 104 with a valve is connected and communicated at the bottom of the stirring tank 1.

[0030] Among them, as shown in Figure 2As shown in the figure, the inner wall scraping mechanism 2 includes a scraping component 21 and a buffer component 22. The scraping component 21 includes a reciprocating lead screw one 211 rotatably connected to the inner wall of the stirring tank 1. The bottom of the reciprocating lead screw one 211 rotatably extends outside the stirring tank 1. A scraper 212 is threadedly connected to the outer wall of the reciprocating lead screw one 211. A slide bar one 213 is fixedly connected to the inner wall of the stirring tank 1, and the slide bar one 213 slidably penetrates through the scraper 212.

[0031] By setting the scraping component 21, it can effectively remove the steel sand, rust and other impurity residues attached to the inner wall, avoid the adverse effects of these residues on the subsequent pickling process, reduce the entry of inner wall attachments into the acid solution, maintain the good chemical properties of the acid solution, and ensure the stability and consistency of the rust removal effect.

[0032] Among them, as Figure 3 shown, the buffer component 22 includes a plurality of grooves 221 opened at the bottom of the scraper 212. Damping devices 222 are fixedly connected to the inner walls of the tops of the plurality of grooves 221. Springs 223 are sleeved on the outer walls of the plurality of damping devices 222. The tops of the plurality of springs 223 are fixedly connected to the scraper 212. A buffer block 224 is fixedly connected to the bottoms of the plurality of damping devices 222. The bottoms of the plurality of springs 223 are fixedly connected to the buffer block 224.

[0033] By setting the buffer component 22, when the scraper 212 descends to the lower part of the device, the buffer block 224 will first touch the steel sand. The pressure exerted on the buffer block 224 when the scraper 212 continues to press down will be buffered by the grooves 221 and the damping devices 222. Moreover, the bottom of the buffer block 224 is designed in an arc shape, thus greatly reducing the damage to the stirring tank 1 caused by the extrusion between the inner wall scraping mechanism 2 and the steel sand during scraping.

[0034] Among them, as Figure 4 shown, the stirring mechanism 3 includes a driving component 31 and a lifting and stirring component 32. The driving component 31 includes a rotating shaft 311 rotatably connected to the inner wall of the stirring tank 1. The bottom of the rotating shaft 311 rotatably extends outside the stirring tank 1. A motor 312 is fixedly connected to the bottom extension part of the rotating shaft 311. A motor sleeve 313 is fixedly connected to the outer wall of the motor 312. The top of the motor sleeve 313 is fixedly connected to the stirring tank 1. A plurality of stirring blocks 314 are fixedly connected to the outer wall of the rotating shaft 311. Pulley wheels 315 are fixedly connected to the bottom extension parts of the rotating shaft 311 and the reciprocating lead screw one 211 respectively. A belt 316 is sleeved on the two pulley wheels 315.

[0035] By setting the driving component 31, it can ensure that other components such as the stirring mechanism and the scraping mechanism can work normally, realize the corresponding functions, and improve the work efficiency while reducing the workload of the staff.

[0036] Among them, as Figure 2 , Figure 4 and Figure 5 shown, the lifting and stirring assembly 32 includes a fixing piece 321 fixedly connected to the outer wall of the rotating shaft 311. A reciprocating lead screw two 322 is fixedly connected to the inner wall of the top of the stirring tank 1. The outer wall of the rotating shaft 311 is rotationally connected to the reciprocating lead screw two 322. A lifting block 323 is threadedly connected to the outer wall of the reciprocating lead screw two 322. Two slide bars two 324 are fixedly connected to the top of the fixing piece 321. The tops of the two slide bars two 324 both slidably penetrate the outer wall of the lifting block 323 and extend to the outside. Two stirring rods 325 are fixedly connected to the outer wall of the lifting block 323.

[0037] By setting the lifting and stirring assembly 32, it can be ensured that the acid solution can uniformly contact the steel sand, avoiding too high or too low local acid solution concentration, making the rust removal process more uniform and comprehensive. By stirring, the chemical reaction speed between the rust on the surface of the steel sand and the acid solution is accelerated, improving the rust removal efficiency. It can also prevent the components in the acid solution from precipitating or stratifying, maintaining the consistency of the acid solution performance.

[0038] A specific application of this embodiment is as follows: When in use, first pour the steel sand to be rust-removed into the mixing tank 1 through the feeding funnel 101, and then pour the pickling solution required for rust removal into the mixing tank 1 through the feeding funnel 101 as well. Start the motor 312 on the motor sleeve 313. The motor 312 drives the mixing block 314 to rotate through the rotating shaft 311, stirring up the steel sand located below to prevent it from accumulating due to sinking to the bottom. At this time, the rotating shaft 311 will also drive the lifting block 323 on the sliding rod two 324 to move up and down on the reciprocating screw rod two 322 through the fixing piece 321 while stirring the steel sand in the mixing tank 1, which can ensure that the acid solution can contact the steel sand evenly, avoid too high or too low local acid solution concentration, make the rust removal process more uniform and comprehensive, accelerate the chemical reaction speed between the rust on the steel sand surface and the acid solution through stirring, improve the rust removal efficiency, and can also prevent the components in the acid solution from precipitating or stratifying, maintaining the consistency of the acid solution performance. When the rotating shaft 311 rotates, the rotating shaft 311 will drive the reciprocating screw rod one 211 to rotate through the pulley 315 and the belt 316, so that the scraper 212 on the sliding rod one 213 moves up and down to scrape the inner wall of the mixing tank 1. Since the density of the steel sand is much greater than the density of water, even if the part that has sunk to the bottom is stirred, a small part of the steel sand will stay at the bottom of the device. When the scraper 212 descends to below the device, the buffer block 224 will first touch the steel sand, and the pressure exerted on the buffer block 224 when the scraper 212 continues to press down will be buffered under the action of the groove 221 and the damper 222. Moreover, the bottom of the buffer block 224 is designed in an arc shape, which greatly reduces the damage to the mixing tank 1 caused by the extrusion between the inner wall scraping mechanism 2 and the steel sand during scraping, enabling the effective removal of the steel sand, rust and other impurity residues attached to the inner wall, avoiding the adverse effects of these residues on the subsequent pickling process, reducing the entry of inner wall attachments into the acid solution, maintaining the good chemical performance of the acid solution, ensuring the stability and consistency of the rust removal effect, preventing the attachments from continuously accumulating in some parts and causing blockage, ensuring the normal flow of the fluid in the device, and maintaining the smooth progress of the pickling operation. When the steel sand in the device is completed with pickling, open the liquid outlet pipe 104 with a valve to make the pickling solution in the device flow out of the device through the liquid outlet pipe 104 with a valve, and then open the support leg 103 to take out the cleaned steel sand in the device.
