Description

Technical Field

[0001] This utility model relates to a stirring device for industrial waste acid recovery, belonging to the field of protective film technology. Background Technology

[0002] Industrial waste acid refers to waste liquid containing strong acids such as sulfuric acid, hydrochloric acid, and nitric acid, generated during industrial production processes in industries such as chemical, metallurgical, electronic, and printing and dyeing. This type of waste acid is typically highly corrosive and reactive, and may contain heavy metals or other harmful substances. Direct discharge without proper treatment can cause serious harm to the environment, equipment, and personnel safety. Therefore, it requires safe management through dedicated storage, recycling, or neutralization treatment. During the industrial waste acid recycling process, stirring is necessary to ensure uniform mixing of the waste acid liquid, prevent sediment buildup, accelerate chemical reactions, and improve the efficiency of neutralization, dilution, or precipitation processes.

[0003] Chinese Patent Publication No. CN 221015664 U discloses a stirring device for industrial waste acid treatment, comprising a stirring device body and a stirring tank. The stirring tank is located inside the stirring device body, and a servo motor is fixedly connected to the bottom of the stirring tank. A rotating shaft is fixedly connected to the output end of the servo motor. This stirring device for industrial waste acid treatment works by using a second fixed block to press a support rod when the stirring tank vibrates, causing the support rod to slide inward. Simultaneously, the sliding sleeve presses a first spring, and the reaction force of the first spring counteracts the force generated by the shaking of the stirring tank, thus achieving a shock absorption effect. When the stirring tank shakes up and down, the reaction force of the second spring further reduces shock absorption, thereby reducing the impact and stress during vibration and also reducing the possibility of waste acid leakage or spillage.

[0004] In the above technology, the mixing component mainly uses the stirring rod in the center of the mixing tank to mix materials. However, the gap between the stirring rod and the inner wall is large, which leads to insufficient mixing of the liquid near the tank wall, forming dead corners or local sedimentation, uneven chemical reaction, reduced recovery efficiency, and increased risk of local acid overconcentration or overheating, affecting the safety and stability of the treatment.

[0005] Therefore, a stirring device for industrial waste acid recovery is proposed. Utility Model Content

[0006] In view of this, the present invention provides a stirring device for industrial waste acid recovery to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: a stirring device for industrial waste acid recovery includes a stirring tank, a box cover is provided on the left and right sides of the top of the stirring tank, a feed pipe is connected around the stirring tank, a support frame is fixedly installed on the outer surface of the stirring tank, an L-shaped plate is fixedly installed on the top of the box cover, a slot is opened on the inner side of the two box covers, and a discharge valve is fixedly installed at the bottom of the stirring tank.

[0008] The surface of the mixing tank is provided with a stirring mechanism, which includes a motor, a second bevel gear, a housing, and mounting rods. The motor is fixedly installed on the right side of the L-shaped plate. The second bevel gear is movably connected to the inner cavity of the two slots through bearings. The housing is set in the inner cavity of the mixing tank. All five mounting rods are located at the bottom of the housing, and stirring rods are fixedly connected to the surface of each of the five mounting rods.

[0009] More preferably, a hollow rod is fixedly connected to the bottom of the second bevel gear, and the bottom of the hollow rod is fixedly connected to the top of the housing. A third bevel gear is movably connected to the bottom of the L-shaped plate, and a connecting rod is fixedly connected to the bottom of the third bevel gear. The connecting rod passes through the interior of the second bevel gear and the hollow rod and extends into the inner cavity of the housing.

[0010] More preferably, a drive gear is fixedly connected to the bottom of the connecting rod, and driven gears are provided around the perimeter of the inner cavity of the housing. The bottoms of the four driven gears and the drive gear are fixedly connected to the tops of the five mounting rods, and the surfaces of the four driven gears mesh with the surfaces of the four drive gears.

[0011] More preferably, the output end of the motor is fixedly connected to a first bevel gear, and the surfaces of the second bevel gear and the third bevel gear mesh with the surface of the first bevel gear.

[0012] More preferably, scraper blades are fixedly installed around the perimeter of the box, and the outer side of the scraper blades is in contact with the inner cavity of the mixing tank.

[0013] More preferably, all fifteen stirring rods are the same size, and all fifteen stirring rods are different heights.

[0015] More preferably, a base plate is fixedly installed at the bottom of the support frame, and anchor bolts are threaded around the top of the base plate.

[0016] The present invention has the following advantages due to the adoption of the above technical solution:

[0017] I. This utility model, through the setting of a stirring mechanism, uses the output of a motor to drive the second and third bevel gears to rotate via a first bevel gear. The rotation of the housing of the second bevel gear synchronously causes the mounting rod and stirring rod to move circumferentially. Simultaneously, the rotation of the third bevel gear drives the connecting rod to rotate the driving gear, which in turn synchronously drives the mounting rod and stirring rod to rotate. This achieves comprehensive and uniform stirring of the liquid, avoiding dead zones and sediment buildup, ensuring a full and uniform chemical reaction, improving recovery efficiency, and maintaining uniform temperature and concentration distribution, reducing the risk of localized overheating or over-concentration. This enhances the safety, stability, and lifespan of the recovery process.

[0018] Second, this utility model, by setting up a scraper, can effectively clean the inner cavity of the mixing tank, preventing waste acid from sticking to the inner wall of the mixing tank and failing to be completely discharged. By setting up stirring rods, the different heights of the stirring rods can effectively prevent collisions between them due to their own lengths when rotating. By setting up fixing bolts, the tank cover can be easily disassembled, facilitating maintenance of the components in the mixing mechanism. By setting up anchor bolts, the equipment can be stabilized as a whole, preventing the equipment from tipping over due to accidental collisions caused by external factors, thus affecting the mixing of waste acid.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model embodiment provides a stirring device for industrial waste acid recovery, including a stirring tank 1, a box cover 4 is provided on the left and right sides of the top of the stirring tank 1, a feed pipe 3 is connected around the stirring tank 1, a support frame 6 is fixedly installed on the outer surface of the stirring tank 1, an L-shaped plate 5 is fixedly installed on the top of the box cover 4, a slot 10 is opened on the inner side of the two box covers 4, and a discharge valve 11 is fixedly installed at the bottom of the stirring tank 1.

[0031] A stirring mechanism 2 is provided on the surface of the mixing tank 1. The stirring mechanism 2 includes a motor 201, a second bevel gear 203, a housing 205, and mounting rods 210. The motor 201 is fixedly installed on the right side of the L-shaped plate 5. The second bevel gear 203 is movably connected to the inner cavity of the two slots 10 via bearings. The housing 205 is located in the inner cavity of the mixing tank 1. Five mounting rods 210 are all located at the bottom of the housing 205. Stirring rods 211 are fixedly connected to the surface of each of the five mounting rods 210. A hollow rod 204 is fixedly connected to the bottom of the second bevel gear 203. The bottom of the hollow rod 204 is fixedly connected to the top of the housing 205. A third bevel gear 206 is movably connected to the bottom of the L-shaped plate 5. A connecting rod 207 is fixedly connected to the bottom of the third bevel gear 206. The connecting rod 207 passes through the second bevel gear 203 and the hollow rod. The interior of 204 extends into the inner cavity of the housing 205. The bottom of the connecting rod 207 is fixedly connected to the driving gear 208. Driven gears 209 are provided around the inner cavity of the housing 205. The bottoms of the four driven gears 209 and the driving gear 208 are fixedly connected to the tops of the five mounting rods 210. The surfaces of the four driven gears 209 mesh with the surfaces of the four driving gears 208. The output end of the motor 201 is fixedly connected to the first bevel gear 202. The surfaces of the second bevel gear 203 and the third bevel gear 206 mesh with the surfaces of the first bevel gear 202. Scraper plates 212 are fixedly installed around the housing 205. The outer side of the scraper plates 212 is in contact with the inner cavity of the mixing tank 1. The fifteen stirring rods 211 are all the same size and the heights of the fifteen stirring rods 211 are all different.

[0032] By setting up a stirring mechanism 2, the first bevel gear 202 drives the second bevel gear 203 and the third bevel gear 206 to rotate via the output of the motor 201. The rotating housing 205 of the second bevel gear 203 rotates synchronously, causing the mounting rod 210 and the stirring rod 211 to move circumferentially. When the third bevel gear 206 rotates, the connecting rod 207 drives the driving gear 208 to rotate. At this time, the driven gear 209 synchronously drives the mounting rod 210 and the stirring rod 211 to rotate, thereby achieving all-round uniform stirring of the liquid, avoiding dead zones and sediment accumulation, ensuring a full and uniform chemical reaction, improving recovery efficiency, maintaining uniform temperature and concentration distribution, reducing the risk of local overheating or over-concentration, and thus improving the safety, stability, and service life of the recovery process.

[0033] Example 2

[0034] like Figure 1 and Figure 2As shown, in one embodiment, the tops of the two box covers 4 are threaded with fixing bolts 7, the bottoms of the twelve fixing bolts 7 are threaded with the inner surface of the mixing tank 1, the bottom of the support frame 6 is fixedly installed with a base plate 8, and the top of the base plate 8 is threaded with anchor bolts 9 around its perimeter.

[0035] By setting the fixing bolts 7, the cover 4 can be easily disassembled, making it convenient to maintain and repair the parts in the mixing mechanism 2. By setting the anchor bolts 9, the equipment as a whole can be stabilized, preventing the equipment from tipping over due to accidental collisions caused by external factors, which would affect the mixing of waste acid.

[0036] In operation, the waste acid is first injected into the inner cavity of the mixing tank 1 through the feed pipe 3. Then, the output of the motor 201 causes the first bevel gear 202 to rotate. Under the action of the first bevel gear 202 meshing with the second bevel gear 203 and the third bevel gear 206, the connecting rod 207 and the hollow rod 204 rotate. As the hollow rod 204 drives the housing 205 to rotate, the scraper 212, the mounting rod 210 and the stirring rod 211 move in a circular motion in sync. As the connecting rod 207 rotates, the driving gear 208 rotates and cooperates with the driven gear 209. The driven gear 209 drives the mounting rod 210 to rotate. At this time, the stirring rod 211 rotates synchronously due to the rotation of the mounting rod 210, and begins to stir the waste acid in the inner cavity of the mixing tank 1. The stirred waste acid is discharged from the inner cavity of the mixing tank 1 through the discharge valve 11, completing the mixing of the waste acid in the inner cavity of the mixing tank 1.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
