Therefore, the above terms should not be understood as limiting the present invention.

[0025] like Figures 1 to 5 The figure shows a shear pump, comprising a pump body 1, wherein the pump body 1 is provided with a vertically arranged pump chamber 2, the pump chamber 2 comprising an overhead feed port 3 and an inlet 4 and a discharge port 5 located on both sides of the pump chamber 2, the inlet 4 allows liquid to flow into the pump chamber 2 to maintain a certain liquid level 6, the discharge port 5 is used to output a mixture mixed with materials, the feed port 3 is provided with a grid 7, a shear knife 8 is provided on the lower side of the grid 7, the shear knife 8 is arranged above the liquid level 6, the grid 7 is used to preliminarily divert the material into a first strip body, the shear knife 8 is used to cut the first strip body into small segments of material, and the small segments of material fall into the liquid level 6 below by gravity for mixing to form the mixture.

[0026] The working principle of the present disclosure can be referred to as follows: the inlet 4 is connected to the liquid supply device, the liquid supply device provides liquid to maintain the pump chamber 2 with a certain liquid level 6, the shear knife 8 cuts the first strip into small segments of material, the small segments of material fall into the liquid surface 6 below by gravity and are mixed to form the mixture, and then the mixture is output through the discharge port 5, the discharge port 5 can be connected to the suction port of the emulsification pump, therefore, the power of the flow from the inlet 4 to the discharge port 5 can rely on the suction force of the emulsification pump, which is conducive to simplifying the power structure of the flow.

[0027] In order to facilitate flow, refinement and anti-clogging purposes, such as Figure 2 , 4 As shown, the inlet 4 and the outlet 5 are coaxially distributed along a straight line.

[0028] In some embodiments, Figure 2 , 3 As shown, the grid 7 is set as a partition, the upper side of the partition is a temporary material bin 23, the partition is provided with a material drop hole 19, and the material drop hole 19 forms a first strip. In this way, the material enters the temporary material bin 23 and is squeezed under the action of gravity and / or pressure, then the first strip is formed through the material drop hole 19, and then cut into small pieces of material by the shearing knife 8, in this example, small pieces, similar to small pills such as vitamins.

[0029] Further, such as Figure 3 As shown, the material drop hole 19 includes two parts, namely a conical hole and a cylindrical hole arranged in sequence from top to bottom. The conical hole allows the flowing material to enter conveniently, while the cylindrical hole organizes the entering material into a cylindrical shape and transports it to the lower side of the grille 7. When the cylindrical material protrudes from the lower side of the grille 7, it can be sheared into small pieces by the shear knife 8.

[0030] In some embodiments, Figure 3 , 4 As shown in Figures 5 and 6, the shearing knife 8 includes a plurality of blades 9 arranged along the circumference of the rotating shaft 11. When these blades 9 rotate, they form a rotating surface, which is located at the lower side of the grille 7. In this way, the rotating shaft 11 and these blades 9 form a rotatable blade disc structure, which is conducive to high-efficiency shearing.

[0031] It is worth noting that Figure 4 As shown, a spray structure 20 is provided near the lower side of the grid 7, and the spray structure 20 is used to initially solidify the material to facilitate the shearing of the first strip by the shearing knife 8. This is more conducive to shearing the material into small pieces.

[0032] The spray structure 20 is, for example, a nozzle. On the one hand, the nozzle sprays water mist toward the lower side of the grille 7 to preliminarily solidify the material. On the other hand, the water mist sprayed by the nozzle is mixed with the material just protruding under the stirring of the rotating blade disc structure, and then the material is preliminarily solidified and sheared by the blade 9 at the same time.

[0033] In some embodiments, Figure 3 , 4 As shown in FIG. 5 , the upper side 10 of the blade 9 is set as a plane parallel to the lower side of the grille 7, and the upper side 10 of the blade 9 is adjacent to or attached to the lower side of the grille 7. In this way, it is more conducive to the shearing purpose, so that the first strip body is not pulled too long, and the small section of the sheared material is thin, which is conducive to thinning.

[0034] In some embodiments, Figure 3 , 4 5, it also includes a drive shaft 12, the upper end of the drive shaft 12 is coaxially detachably connected to the rotating shaft 11. In this way, it is convenient to assemble and is also conducive to the maintenance of the cutter head structure through disassembly and assembly at a later stage.

[0035] In some embodiments, Figure 3 As shown, the pump body 1 is also provided with a base 13, on which the pump body 1 is arranged, and the drive shaft 12 passes through the bottom of the pump chamber 2 and then extends downward to the base 13, and the base 13 is provided with a driver, which drives the drive shaft 12 to rotate. In this way, the structure is compact.

[0036] Furthermore, the driver includes an electric motor 14 and a transmission box 15 , and the electric motor 14 , the transmission box 15 , and the drive shaft 12 are sequentially connected in transmission.

[0037] In some embodiments, Figure 1 , 3 As shown, the base 13 includes a bottom plate 16 and a support 22, the support 22 supports the bottom plate 16, the electric motor 14 and the pump body 1 are arranged in parallel on the upper side of the bottom plate 16, and the transmission box 15 is arranged on the lower side of the base 13. The transmission box 15 is provided with a driving wheel 17 and a driven wheel 18, the driving wheel 17 is connected to the output shaft of the electric motor 14, and the driven wheel 18 is connected to the lower end of the driving shaft 12. In this way, the structure is compact.

[0038] The driving wheel 17 and the driven wheel 18 can be gears or pulleys. In this example, they are pulleys. The driving wheel 17 and the driven wheel 18 are connected by a transmission belt 21.

[0039] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.
