Description

A device for stirring viscous materials

Technical Field

The invention relates to the technical field of stirring devices, and in particular to a stirring device for viscous materials.

Background Art

The agitators currently in use have a rod climbing phenomenon when processing viscous materials. This phenomenon is mainly due to the fact that the viscoelastic fluid is affected by the normal stress during the stirring process, causing the fluid to be stretched along the stirring shaft and entangled on it. And as the running time of the agitator increases, the material accumulated on the stirring shaft gradually increases. This part of the fluid is difficult to flow into the tank during the stirring and mixing process, and the convection and diffusion of the fluid in the tank are interrupted. In addition, the viscoelastic fluid is very viscous and has poor fluidity. In production, the drainage cannot quickly remove the fluid adhering to the shaft. If this continues for a long time, serious agglomeration will occur, which will seriously affect the operating efficiency of the agitator, and even require regular shutdown and cleaning to maintain its stable operation. In addition, the filamentary materials in the stirring materials are easily entangled on the stirring shaft, which further leads to uneven material stirring effect and affects the quality and stability of the final product.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

An embodiment of a viscous material stirring device of the present invention is shown in FIGS. 1 to 11 .

A viscous material stirring device includes a shell 100 and a stirring member 200. The shell 100 is provided with two ear plates 101 for hoisting the shell 100, so as to facilitate the installation of the viscous material stirring device before use. The shell 100 is provided with a feed port 102 and a discharge port 103, and the viscous material to be stirred can enter the shell 100 from the feed port 102 and be discharged from the discharge port 103 after being stirred. The viscous material to be stirred includes but is not limited to raw materials for producing recycled tableware, that is, before producing recycled tableware, raw starch, cellulose and water are mixed together to form a viscous material, and the viscous material needs to be stirred first and then wait for the next step of production.

The stirring member 200 is installed in the housing 100. The size of the stirring member 200 in the housing 100 along the first direction is constant, and the first direction is the vertical direction. The stirring member 200 is a conical spiral spring bar, and the cross-section of the spring bar itself is in the shape of a triangle. The stirring member 200 can revolve around the first direction in the housing 100. The two ends of the stirring member 200 along the first direction are respectively called the first end 201 and the second end 202, and the first end 201 and the second end 202 can respectively rotate around the first direction.

The stirring member 200 has a first state and a second state. In the first state, the first end 201 and the second end 202 of the stirring member 200 both rotate forwardly around the first direction, and the speed of the first end 201 of the stirring member 200 rotating on its own is greater than the speed of the second end 202 of the stirring member 200 rotating on its own. In the second state, the first end 201 of the stirring member 200 rotates in the reverse direction around the first direction, and the second end 202 of the stirring member 200 rotates forwardly around the first direction.

Specifically, a plurality of stirring members 200 are provided, and the plurality of stirring members 200 are installed in the housing 100 and are evenly distributed around the first direction in the housing 100 . In the present embodiment, three stirring members 200 are provided.

In this embodiment, the stirring member 200 is set as a conical spiral spring bar. After the material to be stirred is fed into the housing 100, the stirring member 200 is switched to the first state. The first end 201 and the second end 202 of the stirring member 200 both rotate in a positive direction around the first direction, and the speed of the first end 201 of the stirring member 200 rotating on its own is greater than the speed of the second end 202 of the stirring member 200 rotating on its own. This makes it possible for the first end 201 to rotate relative to the second end 202 to store force during the self-rotation of the stirring member 200. During the rotation of the first end 201 relative to the second end 202, the stirring member 200 itself is activated by the spiral structure. Under the present invention, the stirring element 200 as a whole will tend to stretch in the first direction, but because the shell 100 limits the size of the stirring element 200 in the first direction, the stirring elements 200 will be compressed close to each other in the first direction. By making the cross-section of the stirring element 200 perpendicular to the spiral direction of the stirring element 200 into a triangle, the stirring elements 200 are compressed close to each other in the first direction, which can shear the bonded material between the two circles and cut off the filamentary material on the stirring element 200, thereby reducing the material bonded and hung on the stirring element 200, stretching and dispersing the particles and components in the viscous material, and making the material stirring more uniform.

The stirring element 200 is then switched to the second state, so that the first end 201 of the stirring element 200 is reversed around the first direction relative to the second end 202 of the stirring element 200. At this time, the stirring element 200 will be reversed and released. During the release process, the stirring direction of the material is changed so that the material is better broken up, the stirring is more uniform, and the stirring effect is better; and during stirring, the entire stirring element 200 is in a state of combined revolution and rotation at the same time. Through the constantly changing motion trajectory, the material in the dead corner area is effectively stirred and redispersed, which can improve the stirring effect and efficiency.

In this embodiment, a viscous material stirring device further includes a first transmission mechanism 300 , and the first transmission mechanism 300 includes a sun gear 310 , a ring gear 320 , a planet carrier 330 and a plurality of planetary parts. A driving motor 110 is arranged on the housing 100, and the sun gear 310 is fixedly mounted on the output shaft of the driving motor 110, so that the sun gear 310 can be mounted on the housing 100 so as to rotate around a first direction. The ring gear 320 is coaxially arranged with the sun gear 310 and is fixedly mounted in the housing 100, and the planetary carrier 330 is coaxially arranged with the sun gear 310 and can be mounted in the housing 100 so as to rotate around a first direction. A plurality of planetary parts are arranged in a one-to-one correspondence with a plurality of stirring members 200, and a plurality of planetary parts are evenly distributed on the planetary carrier 330 around a first direction, and the planetary parts can be mounted on the planetary carrier 330 so as to rotate around a first direction. The planetary parts include planetary wheels 340, and the planetary wheels 340 are meshed with the sun gear 310 and the ring gear 320 at the same time, and the first end 201 of the stirring member 200 can rotate with the corresponding planetary wheel 340.

Further, there are N planetary gears 340, and N is an odd number. The plurality of planetary gears 340 are sequentially arranged on the planet carrier 330 along the second direction, the second direction is the radial direction of the ring gear 320, and the two planetary gears 340 at both ends in the second direction are respectively meshed with the sun gear 310 and the ring gear 320, the diameters of the plurality of planetary gears 340 are equal, and the diameter of the sun gear 310 is greater than the diameter of the planetary gears 340. The first end 201 of the agitator 200 can rotate synchronously with the planetary gears 340 meshed with the ring gear 320 in the second direction.

Specifically, three planetary gears 340 are provided, and the three planetary gears 340 are sequentially arranged on the planet carrier 330 along the second direction.

In this embodiment, a viscous material stirring device further includes a second transmission mechanism 400, which has the same structure as the first transmission mechanism 300, and the second end 202 of the stirring member 200 can rotate with the corresponding planetary gear 340 of the second transmission mechanism 400. When the stirring member 200 is in the first state, the rotation speed of the sun gear 310 of the first transmission mechanism 300 is greater than the rotation speed of the sun gear 310 of the second transmission mechanism 400.

By setting the first transmission mechanism 300 and the second transmission mechanism 400, taking the first transmission mechanism 300 as an example, when in use, the sun gear 310 is driven to rotate by the driving motor 110, and the rotation of the sun gear 310 will drive the planetary gear 340 to rotate, and because the ring gear 320 is fixed, the planetary gear 340 will also revolve around the first direction between the sun gear 310 and the ring gear 320, that is, the planetary gear 340 will rotate while rotating, and drive the first end 201 of the stirring member 200 to rotate while rotating around the first direction. And the second transmission mechanism 400 will also drive the second end 202 of the stirring member 200 to rotate while rotating around the first direction and revolving around the first direction according to the above transmission principle.

By providing a plurality of planetary gears 340 and making the diameter of the sun gear 310 larger than the diameter of the planetary gear 340, it is possible to ensure that the orbital speed and the self-rotation speed of the planetary gear 340 are in a relatively fast state, thereby ensuring that when the planetary gear 340 drives the first end 201 of the agitator 200 to rotate, the orbital speed and the self-rotation speed of the first end 201 of the agitator 200 are in a relatively fast state.

Because when the stirring member 200 is in the first state, the rotation speed of the sun gear 310 of the first transmission mechanism 300 is greater than the rotation speed of the sun gear 310 of the second transmission mechanism 400. This makes the first end 201 of the stirring member 200 rotate faster than the second end 202 of the stirring member 200, and the revolution speed of the first end 201 of the stirring member 200 will also be greater than the revolution speed of the second end 202 of the stirring member 200, which makes the revolution track of the first end 201 of the stirring member 200 ahead of the revolution track of the second end 202 of the stirring member 200 corresponding to it, that is, with reference to FIG8, the stirring member 200 itself has a tendency to tilt, so that when stirring, the stirring range of the stirring member 200 is wider, and the materials in the dead angle area in the middle of the housing 100 can also be stirred, further improving the uniformity of stirring.

Furthermore, two partition plates 120 are rotatably disposed in the housing 100, and the two partition plates 120 define a first chamber, a second chamber, and a third chamber that are sequentially disposed in a first direction and are independent of each other in the housing 100. The first transmission mechanism 300 is installed in the first chamber, the stirring member 200 is installed in the second chamber, and the second transmission mechanism 400 is installed in the third chamber. The feed port 102 and the discharge port 103 are both opened on the second chamber.

The first chamber, the second chamber and the third chamber are separated by providing a partition plate 120 to prevent viscous materials from entering the first chamber and the third chamber.

In this embodiment, the first end 201 of the stirring member 200 is mounted on the corresponding planetary gear 340 through the first connecting block 210. The first connecting block 210 is cylindrical and is coaxially arranged with the planetary gear 340. The first connecting block 210 is provided with an annular groove 211 on one side close to the stirring member 200 along the first direction. The first end 201 of the stirring member 200 is fixedly provided with a rotating block 203, and the rotating block 203 can rotate around the first direction in the annular groove 211. A limiting block 213 is provided in the annular groove 211. When the stirring member 200 is in the first state, the limiting block 213 limits the rotating block 203 from rotating around the first direction in the annular groove 211. When the stirring member 200 is in the second state, the limiting block 213 allows the rotating block 203 to rotate around the first direction in the annular groove 211.

An electromagnet 212 is arranged in the annular groove 211, and the limit block 213 cooperates with the keyway of the annular groove 211, so that the limit block 213 can move in the annular groove 211 along the first direction, and can rotate synchronously with the first connecting block 210. In the rotation direction of the first connecting block 210, the rotating block 203 is located in front of the limit block 213 and abuts against the limit block 213. Referring to FIG. 9, when the first connecting block 210 rotates clockwise, the side close to the arrow of the clockwise rotation is called the front, and the side away from the arrow of the clockwise rotation is called the rear. A sensor 220 is arranged on the stirring member 200, and the sensor 220 is electrically connected to the electromagnet 212. When the stirring member 200 is compressed in the first direction until two adjacent circles of the elastic bar abut, the electromagnet 212 is energized and attracted to the limit block 213, so that the limit block 213 moves along the first direction and is separated from the rotating block 203.

Specifically, the rotating block 203 is a sphere or an arc-shaped block, so that the rotating block 203 can rotate around the first direction in the annular groove 211. The second end 202 of the stirring member 200 is installed on the corresponding planetary gear 340 through the second connecting block 230. The second connecting block 230 is cylindrical and is coaxially arranged with the planetary gear 340. The second end 202 of the stirring member 200 is fixedly connected to the second connecting block 230.

In this embodiment, an electromagnet 212 and a limit block 213 are provided. Since the limit block 213 is in contact with the rotating block 203 in the initial state, when the first connecting block 210 revolves around the first direction and rotates around the first direction along with the corresponding planetary gear 340, the rotation of the first connecting block 210 will drive the limit block 213 to rotate, thereby driving the first rotating block 203 in contact with the limit block 213 to rotate, so that the first rotating block 203 drives the first end 201 of the stirring member 200 to rotate synchronously, that is, the first end 201 will rotate relative to the second end 202 to store force.

When the stirring element 200 is compressed and brought close to each other in the first direction until two adjacent circles of the elastic bar abut against each other, the sensor 220 transmits a signal to the electromagnet 212, and the electromagnet 212 is energized and attracted to the limit block 213, so that the limit block 213 moves in the first direction and is misaligned with the rotating block 203, and the limiting function of the limit block 213 is lost. The first end 201 of the rotating block 203 is reversed around the first direction relative to the second end 202 of the stirring element 200 and released. During the release process, the stirring direction of the material is changed, so that the material is better broken up, the stirring is more uniform, and the stirring effect is better.

In combination with the above embodiments, the specific working process is as follows:

When in use, the viscous material to be stirred is fed into the housing 100 from the feed port 102. After the material to be stirred is fed into the housing 100, the first transmission mechanism 300 and the second transmission mechanism 400 are started. Taking the first transmission mechanism 300 as an example, when in use, the sun gear 310 is driven to rotate by the driving motor 110. The rotation of the sun gear 310 will drive the planetary gear 340 to rotate. Since the ring gear 320 is fixed, the planetary gear 340 will also revolve around the first direction between the sun gear 310 and the ring gear 320, that is, the planetary gear 340 will rotate while rotating on its own and revolve around the first direction, and drive the first end 201 of the stirring element 200 to rotate on its own and revolve around the first direction. And the second transmission mechanism 400 will also drive the second end 202 of the stirring element 200 to rotate on its own and revolve around the first direction according to the above transmission principle.

Because when the stirring member 200 is in the first state, the rotation speed of the sun gear 310 of the first transmission mechanism 300 is greater than the rotation speed of the sun gear 310 of the second transmission mechanism 400. This makes the first end 201 of the stirring member 200 rotate faster than the second end 202 of the stirring member 200.

At this time, the limit block 213 is in contact with the rotating block 203. Therefore, when the first connecting block 210 revolves around the first direction and rotates around the first direction along with the corresponding planetary gear 340, the rotation of the first connecting block 210 will drive the limit block 213 to rotate, and then promote the first rotating block 203 abutting against the limit block 213 to rotate, so that the first rotating block 203 drives the first end 201 of the stirring member 200 to rotate synchronously, that is, the first end 201 will rotate relative to the second end 202 to accumulate force.

During the rotation of the first end 201 relative to the second end 202, under the action of the spiral structure of the stirring element 200 itself, the stirring element 200 as a whole will tend to stretch in the first direction, but because the outer shell 100 limits the size of the stirring element 200 in the first direction, the stirring elements 200 will be compressed close to each other in the first direction. By making the cross-section of the stirring element 200 perpendicular to the spiral direction of the stirring element 200 into a triangle, the stirring elements 200 are compressed close to each other in the first direction, which can shear the bonded material between the two circles and cut off the filamentary material on the stirring element 200, thereby reducing the material bonded and hung on the stirring element 200, stretching and dispersing the particles and components in the viscous material, and making the material stirring more uniform.

Moreover, the revolution speed of the first end 201 of the stirring element 200 will also be greater than the revolution speed of the second end 202 of the stirring element 200, which makes the revolution trajectory of the first end 201 of the stirring element 200 ahead of the revolution trajectory of the corresponding second end 202 of the stirring element 200, that is, referring to Figure 8, the stirring element 200 itself has a tendency to tilt, so that during stirring, the stirring range of the stirring element 200 is wider, and the material in the dead corner area in the middle of the shell 100 can also be stirred, further improving the uniformity of stirring.

When the stirring element 200 is compressed and brought close to each other in the first direction until two adjacent circles of the elastic bar abut against each other, the sensor 220 transmits a signal to the electromagnet 212, and the electromagnet 212 is energized and attracted to the limit block 213, so that the limit block 213 moves in the first direction and is misaligned with the rotating block 203, and the limiting function of the limit block 213 is lost. The first end 201 of the rotating block 203 is reversed around the first direction relative to the second end 202 of the stirring element 200 and released. During the release process, the stirring direction of the material is changed, so that the material is better broken up, the stirring is more uniform, and the stirring effect is better.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
