Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, and more specifically, to an L-shaped self-cleaning stirring and mixing device. Background Art

[0002] The multi-material uniform mixing head is a common mixing equipment, which is widely used in various fields such as construction, furniture, and automobiles. Its main function is to mix multiple raw materials evenly through a series of orderly operations of the mixing head. The evenly mixed raw materials enter the next process to make the required products.

[0003] Take the uniform mixing of raw materials A and B as an example. The existing L-shaped mixing head is operated by two pistons, large and small. The mixing chamber is the space vacated by the small piston retreating. The small space vacated by the small piston can minimize the energy loss of raw materials A and B during impact, ensuring that raw materials A and B collide and mix evenly at high speed. The mixed raw materials A and B continue to move forward, turn 90 degrees and enter the space vacated by the large piston. The large space vacated by the large piston allows the mixed raw materials to be spit out at a lower forward speed, reducing splashing and optimizing the use environment.

[0004] The fundamental reason why the existing L-type gun can mix evenly is that the A and B raw materials rush out at high speed and collide with each other to mix. However, if the viscosity of the A and B raw materials is high, the viscosity difference is large, the mixing ratio difference is large, or the raw materials contain solid particles, or the forward speed is insufficient, the flow rate is too small, it will cause uneven collision and mixing at the nozzle; when the unevenly mixed A and B raw materials leave the small mixing chamber in front of the nozzle, they will enter the large space vacated by the large piston in a laminar state. At this time, the unevenly mixed A and B raw materials will no longer have the opportunity to be mixed twice. Finally, the A and B raw materials are spit out of the mixing head in an unevenly mixed state and enter the next process, which will affect the quality of the product and even cause the product to be scrapped.

[0005] Therefore, the utility model provides an L-shaped self-cleaning stirring and mixing device to solve the problems existing in the prior art and meet production needs. Utility Model Content

[0033] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0034] like Figure 1-Figure 4 As shown, the utility model provides an L-shaped self-cleaning stirring and mixing device, comprising: a stirring and mixing device body 100, the stirring and mixing device body 100 comprises a main oil cylinder 1 and a gun mixing part 2, wherein the gun mixing part 2 is installed at the front end of the main oil cylinder 1, and a sub-oil cylinder piston part 4 is provided above the gun mixing part 2, so that the stirring and mixing device body 100 presents an L-shape;

[0035] A main piston shaft 3 is provided in the main oil cylinder 1, and a static mixing head 32 is provided at the front end of the main piston shaft 3. The static mixing head 32 extends into the gun mixing section chamber 20 in the gun mixing section 2. A first material inlet 21 and a second material inlet 22 are respectively arranged on both sides of the gun mixing section 2. The auxiliary oil cylinder piston part 4, the first material inlet 21 and the second material inlet 22 are all connected to the gun mixing section chamber 20, wherein the auxiliary oil cylinder piston part 4 provides a mixing space 40 for material A and material B, and the first material inlet 21 and the second material inlet 22 are respectively used to transport material A and material B to the above-mentioned mixing space 40 for the first collision mixing. The A and B materials mixed for the first time turn 90 degrees and enter the gun mixing section chamber 20. After the action of the static mixing head 32, the A and B mixed materials after the first collision mixing are evenly mixed again. The A and B mixed materials after the second mixing enter the required equipment through the mixed material outlet at the front end of the gun mixing section 2, thereby making the required products.

[0036] Through the design of the main oil cylinder 1, the gun mixing part 2, the main piston shaft 3, the static mixing head 32 and other structures, when facing A and B raw materials with high viscosity, high viscosity difference, high ratio difference or containing solid particles, the A and B raw materials can still be uniformly mixed.

[0037] Exemplary Body Piston Shaft

[0038] like Figure 2 , Figure 4 , Fig.11 As shown, further, some embodiments of the utility model provide a specific structure of the main piston shaft 3, the main piston shaft 3 of the structure has a main piston head 30 and a main shaft body 31, the main piston head 30 is installed in the main oil cylinder 1, and the main shaft body 31 is installed at the front end of the main piston head 30, further, a static mixing head 32 is arranged at the front end of the main shaft body 31, and the static mixing head 32 enters the gun mixing part chamber 20, specifically, the static mixing head 32 includes a plurality of spiral mixing units 321 connected vertically in sequence, so the A and B materials mixed for the first time turn 90 degrees and enter the gun mixing part chamber 20, under the action of the conveying injection pressure, the A and B mixtures can collide and mix the mixed A and B mixtures 200 again after multiple spiral rotations along the plurality of spiral mixing units 321 in the static mixing head 32, and the A and B mixtures after the secondary mixing enter the required equipment through the mixture outlet at the front end of the gun mixing part 2, thereby making the required products.

[0039] Through the above-mentioned structural arrangement, the stirring and mixing device body 100 in the utility model has a static mixing head 32, which is a highly efficient mixing device without moving parts. The flow state of the fluid is changed through the mixing unit body to achieve good dispersion and sufficient mixing between different fluids.

[0040] The working principle of the static mixing head 32 mainly includes the following points:

[0041] 1. Division effect: When the raw material passes through each spiral mixing unit 321 of the static mixing head 32, it will be divided into two parts, and then continue to be divided in the next spiral mixing unit 321. In this way, the volume of the raw material will gradually decrease each time it passes through a spiral mixing unit 321, thereby promoting mixing between the raw materials.

[0042] 2. Conversion effect: The flow direction of the raw material changes when passing through each spiral mixing unit 321 of the static mixing head 32. The flow direction changes along the streamline shape surface twisted by the spiral mixing unit 321, causing the raw material to flow in an axial direction. This flow not only pushes the liquid flow in the center of the pipeline to the periphery, but also pushes the peripheral fluid to the center of the pipeline, causing the raw material to stretch and mix along the spiral mixing unit 321, thereby promoting the sequential thinning and mixing of the raw material layers.

[0043] 3. Reversal effect: The raw materials subjected to right-handed reflux through the spiral mixing unit 321 are reversely rotated in the next spiral mixing unit 321. The impact of this rapid flow will stir the raw materials, similar to the reverse action of a washing machine, further promoting the mixing of the raw materials.

[0044] The static mixing head 32 utilizes spiral mixing units 321 of different specifications to cut, shear, rotate and remix the two raw materials, and in this process the two raw materials are evenly mixed.

[0045] Materials A and B are mixed by collision and secondary mixing in a static mixing head, ultimately achieving uniform mixing of high viscosity, high viscosity difference, high ratio difference and raw materials containing solid particles.
