Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a vertical mixer with variable speed lifting and rotating mixing blades. Background Technology

[0002] As a widely used piece of equipment in industrial production and daily life, mixers play a crucial role in many fields. In the food processing industry, they are used to mix ingredients such as flour, egg liquid, and sauces to make bread, cakes, seasonings, and other products. In the chemical industry, mixers can fully mix various chemical raw materials, promote chemical reactions, and produce chemical products such as plastics, rubber, and coatings. In construction, mixers are used to mix materials such as cement, sand, gravel, and water to prepare concrete.

[0003] A search revealed that Chinese patent CN 222305568 U, authorized in the field of fertilizer production technology, discloses a vertical mixer with variable-speed lifting and rotating stirring blades. The mixer includes a mixing tank, with a lifting assembly on the right side. The lifting assembly includes a support rod, with a first motor fixedly connected to the bottom of the inner cavity of the support rod. A threaded rod is fixedly connected to the output shaft of the first motor, and a threaded cylinder is threadedly connected to the top of the threaded rod. A tank cover is fixedly connected to the top of the threaded cylinder. This invention, by setting up the lifting assembly, can drive the stirring assembly to move up and down within the mixing tank, thereby expanding the stirring range and agitating the materials at the top and bottom of the mixing tank, achieving uniform stirring. The stirring assembly allows for adjustment of the stirring speed of the stirring rod as needed, resulting in energy savings, extending the service life of the device, and further improving the uniformity of material mixing.

[0004] The mixer in the aforementioned patent still has some shortcomings. Because the mixing blades of traditional vertical mixers usually rotate at a fixed speed, it is difficult to adjust them according to the characteristics of the material and the mixing stage. In addition, the mixing blades cannot move up and down, so they cannot fully mix the mixture at different heights, which makes it easy for the upper and lower layers of material to separate, resulting in uneven mixing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vertical mixer with variable speed lifting and rotating mixing blades. This solves the problems of traditional vertical mixers where the mixing blades typically rotate at a fixed speed, making it difficult to adjust according to the characteristics of the material and the mixing stage. Furthermore, the mixing blades cannot be lifted up and down, making it impossible to fully mix the mixture at different heights, which can easily lead to stratification of the upper and lower layers of material and result in uneven mixing.

[0006] This utility model provides the following technical solution: a vertical mixer with variable speed lifting and rotating stirring blades, including a stirring support frame, with support legs evenly arranged around the bottom of the stirring support frame, a variable speed stirring assembly on the stirring support frame, and a stirring blade lifting assembly on the top of the variable speed stirring assembly.

[0007] The variable speed mixing assembly includes a mixing tank disposed on the side of the mixing support frame. Two side fixing plates are symmetrically fixed on both sides of the mixing tank, and the bottom ends of the side fixing plates are fixedly connected to the mixing support frame. A feeding port is opened on the side of the top of the mixing tank. Two rotating grooves are symmetrically opened on both sides of the inner wall of the feeding port. A closing plate is disposed in the feeding port. Two rotating shafts are symmetrically arranged on both sides of the closing plate. The rotating shafts are rotatably connected to the inner wall of the rotating grooves. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the closing plate, and the other end of the torsion spring is connected to the inner wall of the rotating grooves. A top through hole is opened in the middle of the top of the mixing tank. A mixing transmission rod is inserted into the top through hole. Three sets of mixing blades are evenly arranged on the body of the mixing transmission rod. A variable speed motor is disposed at the top of the mixing transmission rod, and the drive end of the variable speed motor is connected to the top of the mixing transmission rod.

[0008] Preferred technical solution 1: A discharge pipe is provided at the bottom of the mixing tank, and a valve is provided on the discharge pipe.

[0009] Preferred technical solution 2: The stirring blade lifting assembly includes a mounting connecting plate disposed on the side of the stirring support frame, a lifting cylinder is installed in the mounting connecting plate, a driving connecting rod is provided at the driving end of the lifting cylinder, a motor connecting plate is connected to the bottom end of the driving connecting rod, and the bottom end of the motor connecting plate is fixedly connected to the top end of the variable speed motor.

[0010] Preferred technical solution 3: A counterweight is provided at the bottom of the side of the stirring support frame.

[0011] This solution enables the mixing support frame to be more stable.

[0012] Preferred technical solution four: The mixing tank consists of a body and a lid.

[0013] This solution makes it easier for users to clean the residue on the inner wall of the mixing tank.

[0014] Preferred technical solution five: Two limiting grooves are symmetrically opened on both sides of the inner wall of the mounting connecting plate, and two limiting sliders are symmetrically arranged on both sides of the motor connecting plate.

[0015] This solution makes the motor connecting plate more stable when pulled by the connecting rod.

[0016] Compared with the prior art, this utility model provides a vertical mixer with variable speed lifting and rotating stirring blades, which has the following beneficial effects:

[0017] (1) This utility model is provided with a variable speed stirring assembly and a stirring blade lifting assembly on the stirring support frame. The variable speed motor in the variable speed stirring assembly is an adjustable variable speed motor, which can adjust the speed of the variable speed motor according to the amount of material to be stirred by the user. The stirring transmission rod drives the stirring blade to stir the material flexibly. The lifting cylinder in the stirring blade lifting assembly can drive the variable speed motor to move up and down by driving the connecting rod, so as to adjust the stirring position of the stirring blade in the stirring tank, so that the stirring blade can fully stir the mixture at different levels in the stirring tank, thereby improving the stirring quality of the material.

[0025] Please see Figure 1-4 ,

[0026] Example 1: A vertical mixer with variable speed lifting and rotating stirring blades includes a stirring support frame 1, support legs 2 are evenly arranged around the bottom of the stirring support frame 1, a variable speed stirring assembly 3 is arranged on the stirring support frame 1, and a stirring blade lifting assembly 4 is arranged on the top of the variable speed stirring assembly 3.

[0027] The variable speed mixing assembly 3 includes a mixing tank 301 disposed on the side of the mixing support frame 1. Two side fixing plates 302 are symmetrically fixed on both sides of the mixing tank 301. The bottom ends of the side fixing plates 302 are fixedly connected to the mixing support frame 1. A feeding port 303 is provided on the side of the top of the mixing tank 301. Two rotating grooves 304 are symmetrically provided on both sides of the inner wall of the feeding port 303. A closing plate 305 is provided inside the feeding port 303. Two rotating shafts 306 are symmetrically arranged on both sides of the closing plate 305. The rotating shafts 306 are rotatably connected to the inner wall of the rotating grooves 304. A torsion spring 307 is sleeved on the rotating shaft 306. One end of the torsion spring 307 is connected to the closing plate 305.

[0028] The other end of the torsion spring 307 is connected to the inner wall of the rotating groove 304. A top through hole 308 is provided in the middle of the top of the mixing tank 301. A stirring transmission rod 309 is inserted into the top through hole 308. Three sets of stirring blades 310 are evenly arranged on the body of the stirring transmission rod 309. A variable speed motor 311 is provided at the top of the stirring transmission rod 309. The drive end of the variable speed motor 311 is connected to the top of the stirring transmission rod 309. A discharge pipe 312 is provided at the bottom of the mixing tank 301. A valve 313 is provided on the discharge pipe 312.

[0029] The stirring blade lifting assembly 4 includes a mounting connecting plate 401 disposed on the side of the stirring support frame 1. A lifting cylinder 402 is installed inside the mounting connecting plate 401. A driving connecting rod 403 is disposed at the driving end of the lifting cylinder 402. A motor connecting plate 404 is connected to the bottom end of the driving connecting rod 403. The bottom end of the motor connecting plate 404 is fixedly connected to the top end of the variable speed motor 311.

[0030] Example 2: The difference between this example and Example 1 is that a counterweight is provided at the bottom of the side of the stirring support frame 1.

[0031] This makes the stirring support frame 1 more stable.

[0032] Example 3: The difference between this example and Example 1 is that the mixing tank 301 is composed of a body and a lid.

[0033] This makes it easier for users to clean the residue on the inner wall of the mixing tank 301.

[0034] Example 4: The difference between this example and Example 1 is that two limiting grooves are symmetrically opened on both sides of the inner wall of the mounting connecting plate 401, and two limiting sliders are symmetrically arranged on both sides of the motor connecting plate 404.

[0035] This makes the motor connecting plate 404 more stable when pulled by the connecting rod 403.

[0036] In this embodiment, since the mixing blades of a traditional vertical mixer usually rotate at a fixed speed, it is difficult to adjust them according to the characteristics of the material and the mixing stage. Furthermore, the mixing blades cannot move up and down, making it impossible to fully mix the mixture at different heights. This causes the upper and lower layers of material to easily separate, resulting in uneven mixing.

[0037] In summary, in practical implementation, when the user needs to stir the materials, the user first rotates the closed plate 305 to put the materials to be stirred into the mixing tank 301 through the feeding port 303.

[0038] Next, the user can start the variable speed motor 311, which is the existing YTSP-90S variable frequency speed control motor. The variable speed motor 311 drives the stirring blades 310 to rotate in the mixing tank 301 through the stirring transmission rod 309, thereby mixing and stirring the materials added to the mixing tank 301 at a variable speed.

[0039] When the user needs to tumble and stir the material to make the upper and lower layers of the material more fully mixed, the lifting cylinder 402 in the stirring blade lifting assembly 4 can be activated. The lifting cylinder 402 drives the connecting rod 403 to move the motor connecting plate 404 up and down. The bottom of the motor connecting plate 404 is fixed with a variable speed motor 311, so that the variable speed motor 311 drives the stirring blade 310 to stir while also moving the stirring blade 310 up and down in the mixing tank 301, thereby making the mixture more fully stirred and more uniformly mixed.
