Description

Technical Field

[0001] The utility model relates to the technical field of stirring knives, in particular to a stirring knife. Background Art

[0002] In modern industrial production, especially in the fields of chemical industry, pharmaceuticals, food processing, etc., as an important mechanical device, the stirring knife is widely used in the processes of material mixing, stirring and crushing. Traditional stirring knives usually adopt a design of single or multiple blades, and generate shear force and frictional force through high-speed rotation to achieve the purpose of mixing and crushing materials.

[0003] However, the existing stirring knives will generate a large centrifugal force during rotation, causing the materials to be pushed towards the container wall. Especially for materials with strong fluidity, it is easy to cause stratification or agglomeration of the materials, which not only reduces the stirring efficiency, but also affects the product quality and production efficiency. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a stirring knife is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a stirring knife, including a rotating shaft, the bottom of the rotating shaft is fixedly connected with a driving shaft, a spiral block is fixedly installed on the outer wall of the rotating shaft, two crushing knife holders are installed on the outer wall of the rotating shaft, the crushing knife holders are installed on the top of the spiral block, a housing is installed on the outer wall of the rotating shaft, and the housing is installed on the top of the crushing knife holders.

[0006] Further: a plurality of annularly distributed filtering holes are opened at the top of the housing.

[0007] Further: a first support block is fixedly connected inside the spiral block, and a second support block is fixedly connected inside the crushing knife holder.

[0008] Further: a clamping block is fixedly connected to the outer wall of the rotating shaft, a first clamping groove is opened inside the first support block, a second clamping groove is opened inside the second support block, a third clamping groove is opened inside the housing, a clamping block is opened inside the housing, and the first clamping groove, the second clamping groove and the third clamping groove all correspond to the clamping block.

[0009] Further: threads are opened at the top of the rotating shaft, and a nut is installed on the threads.

[0010] Further: a baffle is fixedly connected to the outer wall of the rotating shaft.

[0011] The utility model has the following beneficial effects:

[0012] Compared with the prior art, by providing a rotating shaft, a spiral block, a crushing tool holder, a housing, a filtering hole and a driving shaft, during use, the motor is turned on to drive the rotating shaft to rotate through the driving shaft. The spiral block, the crushing tool holder and the housing can be simultaneously driven by the rotating shaft to rotate at high speed. At this time, the material at the bottom of the mixing barrel will enter the interior of the housing through the suction force generated by the rotation of the spiral block, and then be shredded by the crushing tool holder rotating at high speed, and then discharged from the top of the housing through the filtering hole. By repeating this process, all the materials in the mixing barrel can be crushed, and at the same time, the materials can be stirred evenly. It can actively suck the materials into the crushing tool holder for crushing and stirring, solving the problem that the centrifugal force generated when the stirring blade rotates in the prior art pushes the materials towards the container wall, resulting in layering or agglomeration of the materials, and reducing the product quality and production efficiency.

[0013] Compared with the prior art, by providing a rotating shaft, a spiral block, a crushing tool holder, a housing, a thread, a nut, a first card slot, a second card slot, a third card slot and a clamping block, during use, the spiral block, the crushing tool holder and the housing are sequentially fixed and installed on the outer wall of the rotating shaft through the first card slot, the second card slot and the third card slot, and are fixed by the clamping block, and then the nut is installed on the thread; after use, the nut is removed and then the spiral block, the crushing tool holder and the housing are taken out for separate cleaning. It can realize quick disassembly and assembly of the parts, facilitate separate cleaning of each part after use, and prevent materials from clogging in the gaps and breeding bacteria.

[0021] When in use, install the device inside the stirring barrel, connect the driving shaft 15 to the motor, then add materials into the stirring barrel, then start the motor to drive the rotating shaft 1 to rotate through the driving shaft 15. The spiral block 2, the crushing knife holders 3 and the housing 4 can be driven by the rotating shaft 1 to rotate at high speed at the same time. At this time, the materials at the bottom of the stirring barrel will enter the inside of the housing 4 through the suction generated by the rotation of the spiral block 2, and then be chopped by the crushing knife holders 3 rotating at high speed, and then discharged from the top of the housing 4. In this way, the materials in the stirring barrel can be completely crushed and the materials can be stirred evenly at the same time.

[0022] A plurality of annularly distributed filtering holes 8 are opened at the top of the housing 4.
