Description

Technical Field

[0001] This utility model relates to the field of de-icing agent production technology, and in particular to a mixing and stirring device for raw materials in de-icing agent production. Background Technology

[0002] De-icing agents are chemicals that lower the melting temperature of ice and snow. Common de-icing agents are made from readily available and inexpensive raw materials, primarily composed of potassium acetate and chloride salts, and are classified based on these two components. De-icing agents melt snow on roads by lowering the melting temperature, facilitating road clearance, and their effects are noticeable at the application site. However, they are also hazardous; studies have found that de-icing agent residues can corrode road surfaces and vehicle tires. Currently, in northern regions with prolonged winters, the primary method for clearing ice and snow from roads is still using sand and snowplows, supplemented by de-icing agents, to ensure smooth traffic flow. During the production of de-icing agents, a mixing and stirring device is required to thoroughly mix various raw materials.

[0003] However, the mixing and stirring devices for raw materials in the production of de-icing agents in related technologies still have shortcomings. Generally, a stirring shaft is used to drive the stirring rod to rotate and stir, resulting in a relatively simple stirring method. This leads to poor mixing and stirring effect, and the mixing is prone to incomplete, incomplete, and uneven mixing, which in turn reduces the quality of de-icing agent production. Therefore, we propose a mixing and stirring device for raw materials in the production of de-icing agents to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a mixing and stirring device for raw materials used in the production of de-icing agents. The device features an upper stirring rod that can initially mix the raw materials, and a lower stirring rod and connecting rod that rotate and oscillate up and down, allowing for diverse mixing methods. This ensures uniform and comprehensive mixing of the raw materials for the production of de-icing agents, resulting in more uniform mixing and improved quality of de-icing agent production.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mixing and stirring device for raw materials used in the production of de-icing agents, comprising a mixing tank, a feeding hopper for feeding raw materials for the production of de-icing agents fixedly connected to the top of the mixing tank, a cover fixedly connected to the top of the mixing tank, a preliminary mixing mechanism provided between the cover and the feeding hopper, the preliminary mixing mechanism including multiple upper stirring rods provided in the feeding hopper, a swing-type mixing and homogenizing mechanism provided between the cover and the mixing tank, the swing-type mixing and homogenizing mechanism including a stirring shaft rotatably disposed at the top of the mixing tank, three lower stirring rods rotatably connected to the front and rear sides of the stirring shaft, multiple connecting rods rotatably connected between adjacent two lower stirring rods, and a discharge pipe fixedly connected to the bottom of the mixing tank, with a control valve provided on the discharge pipe.

[0006] A further feature of this invention is that the preliminary stirring and mixing mechanism includes a drive motor fixedly connected to one side of the cover, a drive shaft fixedly connected to the output shaft of the drive motor, multiple upper stirring rods fixedly connected to the outside of the drive shaft, upper bearings fixedly connected to both sides of the feed hopper, and the drive shaft fixedly sleeved inside the inner rings of the two upper bearings.

[0007] By adopting the above technical solution, the weighed raw materials for the production of snow melting agents are poured into the feed hopper, and the drive motor is started. The drive motor drives the drive shaft and multiple upper stirring rods to rotate, thereby initially mixing the raw materials for the snow melting agents.

[0008] A further feature of this invention is that a fixed base is fixedly connected to one side of the cover, and the drive motor is fixedly connected to the top of the fixed base.

[0009] By adopting the above technical solution, the drive motor can be supported and fixed to ensure its stable operation.

[0010] A further feature of this invention is that the up-and-down swing-type stirring and mixing mechanism includes a lower bevel gear fixedly connected to the top of the stirring shaft, an upper bevel gear fixedly sleeved on the outside of the drive shaft, and an inclined surface opened on the inner wall of the top of the cover. The upper bevel gear meshes with the lower bevel gear. A turntable is fixedly sleeved on the outside of the stirring shaft. Two springs are fixedly connected to the top of the turntable. Wear-resistant heads are fixedly connected to the top of the springs. Both wear-resistant heads are movably abutting against the inclined surface. A lifting rod is fixedly connected to the bottom of the wear-resistant head. A connecting frame is rotatably connected to the bottom of the lifting rod. The bottom ends of the two connecting frames are rotatably connected to the top of the corresponding lower stirring rod.

[0011] By adopting the above technical solution, the drive shaft drives the upper bevel gear to rotate, which in turn drives the lower bevel gear and the stirring shaft to rotate. The stirring shaft then drives multiple lower stirring rods and connecting rods to rotate, thereby further mixing and homogenizing the de-icing agent raw materials. Simultaneously, the stirring shaft drives the turntable to rotate, which in turn drives the two lifting rods and the wear-resistant head to rotate. The inclined surface of the cover is also made of wear-resistant material, making it more wear-resistant and durable. During rotation, the wear-resistant head will be squeezed by the inclined surface. When the wear-resistant head rotates to the left, it is squeezed to the bottom, thereby driving the lifting rods and connecting frame to move. At the bottom of the movement, the connecting frame drives the lower stirring rod above to deflect downwards to the bottom. Under the linkage of the connecting rod, the two lower stirring rods below will also deflect downwards to the bottom. Similarly, when rotating from the left to the right, the wear-resistant head and the connecting frame are no longer squeezed by the inclined plane. At this time, under the elastic force of the spring, the connecting frame moves to the top. At this time, the lower stirring rod and the connecting rod deflect upwards, thereby driving the lower stirring rod and the connecting rod to rotate and swing up and down repeatedly. This makes the mixing method diverse and can evenly and comprehensively mix the raw materials for the de-icing agent production, making the mixture more uniform and improving the production quality of the de-icing agent.

[0012] A further feature of this invention is that a lower bearing is fixedly fitted inside the mixing tank, the turntable is fixedly fitted inside the inner ring of the lower bearing, and retaining rings are fixedly connected to the top and the inner wall of the top of the mixing tank, with the lower bearing movably abutting between the two retaining rings.

[0013] By adopting the above technical solution, the turntable can be supported, making its rotation more stable. The retaining ring increases the load on the turntable, preventing the turntable from being squeezed off when the wear-resistant head is under pressure.

[0014] A further feature of this invention is that the top of the turntable has two sliding holes, two lifting rods are slidably fitted into the corresponding sliding holes, and two springs are respectively fitted onto the outside of the corresponding lifting rods.

[0015] By adopting the above technical solution, the lifting rod and spring can be guided, making their lifting more stable.

[0016] A further feature of this invention is that the bottom of the mixing tank is fixedly connected to three support legs, which are distributed in a circumferentially spaced manner based on the mixing tank.

[0017] By adopting the above technical solution, the mixing tank can be stably supported.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model involves pouring various weighed raw materials for snow melting agent production into the feed hopper, starting the drive motor, and driving the drive shaft and multiple upper stirring rods to rotate, thereby initially stirring and mixing the raw materials for snow melting agent.

[0020] 2. The drive shaft of this utility model drives the upper bevel gear to rotate, the upper bevel gear drives the lower bevel gear and the stirring shaft to rotate, and the stirring shaft drives the rotation of multiple lower stirring rods and connecting rods, thereby enabling the de-icing agent raw materials to be stirred and mixed again.

[0021] 3. This utility model uses a stirring shaft to drive the rotation of a turntable, which in turn drives the rotation of two lifting rods and the wear-resistant head. During rotation, the wear-resistant head is squeezed by the inclined plane. When the wear-resistant head rotates to the left, it is squeezed to the bottom, which in turn drives the lifting rod and the connecting frame to move to the bottom. The connecting frame drives the lower stirring rod above to deflect downwards to the bottom. Under the linkage of the connecting rod, the two lower stirring rods below will also deflect downwards to the bottom. Similarly, when rotating from the left to the right, the wear-resistant head and the connecting frame are no longer squeezed by the inclined plane. At this time, under the elastic force of the spring, the connecting frame moves to the top. At this time, the lower stirring rod and the connecting rod deflect upwards, which in turn drives the lower stirring rod and the connecting rod to rotate and swing up and down. This makes the stirring method diverse and can evenly and comprehensively stir and mix the raw materials for the de-icing agent production, making the mixture more uniform and improving the quality of the de-icing agent production.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] See Figure 1 — Figure 4 This utility model provides a mixing and stirring device for raw materials used in the production of de-icing agents, including a mixing tank 1. The top of the mixing tank 1 is fixedly connected to a feeding hopper 2 for feeding raw materials used in the production of de-icing agents. A cover 3 is fixedly connected to the top of the mixing tank 1. A preliminary mixing mechanism 4 is provided between the cover 3 and the feeding hopper 2. The preliminary mixing mechanism 4 includes multiple upper stirring rods 44 disposed in the feeding hopper 2. A swing-type mixing and blending mechanism 5 is provided between the cover 3 and the mixing tank 1. The swing-type mixing and blending mechanism 5 includes a stirring shaft 501 rotatably disposed on the top of the mixing tank 1. Three lower stirring rods 502 are rotatably connected to the front and rear sides of the stirring shaft 501. Multiple connecting rods 503 are rotatably connected between two adjacent lower stirring rods 502.

[0030] Specifically, the bottom of the mixing tank 1 is fixedly connected to the discharge pipe 6, and a control valve is installed on the discharge pipe 6.

[0031] Specifically, refer to Figures 1-3 The preliminary mixing mechanism 4 includes a drive motor 42 fixedly connected to one side of the cover 3, a drive shaft 43 fixedly connected to the output shaft of the drive motor 42, and multiple upper stirring rods 44 fixedly connected to the outside of the drive shaft 43.

[0032] Using the above method: the weighed raw materials for the production of various de-icing agents are poured into the feed hopper 2, the drive motor 42 is started, and the drive motor 42 drives the drive shaft 43 and multiple upper stirring rods 44 to rotate, thereby initially mixing the raw materials for the de-icing agents.

[0033] Specifically, upper bearings 45 are fixedly connected to both sides of the feed hopper 2, and the drive shaft 43 is fixedly sleeved in the inner ring of the two upper bearings 45, which can support the drive shaft and make its rotation more stable.

[0034] Specifically, a fixed base 41 is fixedly connected to one side of the cover 3, and the drive motor 42 is fixedly connected to the top of the fixed base 41, which can support and fix the drive motor.

[0035] Specifically, refer to Figures 1-4 The up-and-down swing mixing mechanism 5 also includes a lower bevel gear 505 fixedly connected to the top of the mixing shaft 501, an upper bevel gear 504 fixedly sleeved on the outside of the drive shaft 43, and an inclined surface 510 opened on the inner wall of the top of the cover 3. The upper bevel gear 504 meshes with the lower bevel gear 505. A turntable 511 is fixedly sleeved on the outside of the mixing shaft 501. Two springs 508 are fixedly connected to the top of the turntable 511. Wear-resistant heads 509 are fixedly connected to the top of the springs 508. Both wear-resistant heads 509 are movably abutting against the inclined surface 510. A lifting rod 512 is fixedly connected to the bottom of the wear-resistant head 509. A connecting frame 513 is rotatably connected to the bottom of the lifting rod 512. The bottom ends of the two connecting frames 513 are respectively rotatably connected to the top of the corresponding lower mixing rod 502.

[0036] Using the above scheme: the drive shaft 43 drives the upper bevel gear 504 to rotate, the upper bevel gear 504 drives the lower bevel gear 505 and the stirring shaft 501 to rotate, the stirring shaft 501 drives the rotation of multiple lower stirring rods 502 and connecting rods 503, thereby further stirring and mixing the de-icing agent raw materials. At the same time, the stirring shaft 501 drives the rotation of the turntable 511, the turntable 511 drives the rotation of two lifting rods 512 and the wear-resistant head 509. The inclined surface 510 of the cover 3 is also made of wear-resistant material, making it more wear-resistant and durable. During rotation, the wear-resistant head 509 will be squeezed by the inclined surface 510. When the wear-resistant head 509 rotates to the left, it is squeezed to the bottom, thereby driving the lifting rods 512. As the connecting frame 513 moves to its lowest position, it causes the lower stirring rod 502 above to deflect downwards to its lowest position. Under the linkage of the connecting rod 503, the two lower stirring rods 502 below will also deflect downwards to their lowest positions. Similarly, when rotating from the left to the right, the wear-resistant head 509 and the connecting frame 513 are no longer squeezed by the inclined plane 510. At this time, under the elastic force of the spring 508, the connecting frame 513 moves to its highest position. At this time, the lower stirring rod 502 and the connecting rod 503 deflect upwards, thereby driving the lower stirring rod 502 and the connecting rod 503 to rotate and swing up and down repeatedly. This allows for diverse mixing methods, enabling uniform and comprehensive mixing of the raw materials for the de-icing agent production, resulting in more uniform mixing and improved quality of the de-icing agent production.

[0037] Specifically, a lower bearing 506 is fixedly sleeved inside the mixing tank 1, and a turntable 511 is fixedly sleeved inside the inner ring of the lower bearing 506.

[0038] Specifically, the top of the mixing tank 1 and the inner wall of the top are fixedly connected with retaining rings 507, and the lower bearing 506 is movably abutted between the two retaining rings 507.

[0039] Specifically, the top of the turntable 511 has two sliding holes, and two lifting rods 512 are slidably sleeved in the corresponding sliding holes, and two springs 508 are respectively sleeved on the outside of the corresponding lifting rods 512.

[0040] Specifically, the bottom of the mixing tank 1 is fixedly connected to three support legs 7, which are distributed in a circumferential manner at equal intervals based on the mixing tank 1.

[0041] In this invention, various raw materials for producing de-icing agents, after being weighed, are poured into the feeding hopper 2. The drive motor 42 is then started, causing the drive shaft 43 and multiple upper stirring rods 44 to rotate, thus initially mixing the de-icing agent raw materials. The raw materials enter the mixing tank 1 from the feeding hopper 2. The drive shaft 43 drives the upper bevel gear 504 to rotate, which in turn drives the lower bevel gear 505 and the stirring shaft 501 to rotate. The stirring shaft 501 then drives multiple lower stirring rods 502 and connecting rods 503 to rotate, further mixing the de-icing agent raw materials. Simultaneously, the stirring shaft 501 drives the turntable 511 to rotate, which in turn drives the two lifting rods 512 and the wear-resistant head 509 to rotate. The inclined surface 510 of the cover 3 is also made of wear-resistant material, making it more wear-resistant and durable. During rotation, the wear-resistant head 509 will be subjected to the force of the inclined surface 510. When the wear-resistant head 509 rotates to the left, it is squeezed to the bottom, which drives the lifting rod 512 and the connecting frame 513 to move to the bottom. The connecting frame 513 drives the lower stirring rod 502 to deflect downward to the bottom. Under the linkage of the connecting rod 503, the two lower stirring rods 502 will be driven to deflect downward to the bottom. Similarly, when rotating from the left to the right, the wear-resistant head 509 and the connecting frame 513 are no longer squeezed by the inclined plane 510. At this time, under the elastic force of the spring 508, the connecting frame 513 moves to the top. At this time, the lower stirring rod 502 and the connecting rod 503 deflect upward, which drives the lower stirring rod 502 and the connecting rod 503 to rotate and swing up and down. This makes the mixing method diverse and can evenly and comprehensively mix the raw materials for the de-icing agent production, making the mixture more uniform and improving the production quality of the de-icing agent.
