Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pumps, and more specifically to an extended-range shear pump. Background Art
[0002] The shear pump, a "new type of low-pressure homogenizing pump," also known as an "emulsifying pump," is a sanitary pump with multiple functions, including dispersion, homogenization, emulsification, and homogenization. Utilizing the latest modern processing techniques and technologies, this high-precision new product is manufactured using a high-precision CNC machining center, intelligent programming, and multi-dimensional precision machining. This product is suitable for use in modern biopharmaceutical, pharmaceutical, food and beverage, and dairy industries, where stringent hygiene, sterility, and cleaning requirements are paramount.
[0003] A shear pump consists of a fixed plate and a rotating plate. The fixed plate is stationary, while the rotating plate rotates at high speed under the influence of a driver. Material is shredded between the fixed and rotating plates and then discharged from the pump. Existing shear pumps typically have low delivery pressures and often require the assistance of a booster pump to discharge the sheared material from the pump body, making the pump structure more complex and increasing costs. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a range-extending shear pump, which has a simple structure and can deliver materials out of the pump without the assistance of other booster pumps, thereby effectively reducing costs.

[0006] After adopting the above structure, the extended-range shear pump of the present invention has the following advantages compared with the prior art:
[0007] Since a plurality of booster blades are provided on the other side of the movable disc of the extended-range shear pump of the present invention, the booster blades are integrally formed with the movable disc; the delivery pressure in the pump cavity can be increased by the added blades, and the material can be delivered out of the pump without the assistance of other booster pumps, thereby effectively reducing costs.
[0008] As an improvement, the boost blades are arc-shaped, and multiple boost blades are arranged centrifugally with the axis of the moving disc as the center. After adopting this structure, the boost effect is better.
[0009] As an improvement, a sleeve is provided in the middle of the movable disc, and a retaining ring is provided on the other side of the movable disc, located outside the sleeve. One end of the booster blade is connected to the retaining ring. This structure simplifies the movable disc, while the retaining ring prevents material from entering the gap between the output shaft and the sleeve, making the structure more reliable.
[0010] As an improvement, the inner wall of the sleeve is provided with a positioning groove; the output shaft of the driver is provided with a positioning ridge that matches the positioning groove, and the positioning ridge is embedded in the positioning groove. With this structure, the positioning ridge and the positioning groove can position the movable plate, which has a simple structure and good positioning effect.
[0011] As an improvement, the other side of the moving disc is partially protruded outward to form the booster blade. With this structure, the booster blade has a simple structure and high strength.
[0012] As an improvement, the pump body is provided with a pump chamber open at both ends, the pump chamber including a shear chamber and a connecting chamber. The end face of the pump body near the connecting chamber is connected to the driver, the output shaft of the driver passes through the connecting chamber and extends into the shear chamber, and the movable disc is connected to the output shaft; the end face of the pump body near the shear chamber is connected to the fixed disc, which is provided with shearing fixed teeth that mesh with the shearing movable teeth; the fixed disc is provided with a feed port, and the pump body is provided with a discharge port on the side wall of the shear chamber, and both the feed port and the discharge port are interconnected with the shear chamber. After adopting this structure, the pump body structure is simple and the shearing effect of the material is good.
[0013] As an improvement, a feed port is provided in the middle of the fixed plate. When the shear pump is operating, material enters through the feed port, is sheared by the fixed shear teeth of the fixed plate and the movable shear teeth of the movable plate, enters the shear chamber, and is discharged through the discharge port. This structure is more reasonable, and the shear pump achieves better shearing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figures 1 to 6 As shown, the present application discloses an extended-range shear pump, comprising a pump body 1 and a driver, wherein the driver is a motor 3.
[0025] The pump body 1 is provided with a pump chamber open at both ends. The pump chamber includes a shear chamber 101 and a connecting chamber 102. The shear chamber 101 and the connecting chamber 102 are interconnected. The end face of the pump body 1 adjacent to the connecting chamber 102 is fixedly connected to the housing of the motor 3. The housing of the motor 3 seals the opening of the connecting chamber 102. The output shaft 301 of the motor 3 passes through the connecting chamber 102 and extends into the shear chamber 101. A movable disc 2 is provided within the shear chamber 101 and is fixedly connected to the output shaft 301.
[0026] A sleeve 201 is provided in the middle of the movable disc 2. The sleeve 201 is fitted over the output shaft 301 of the motor 3. A positioning groove 202 is provided on the inner wall of the sleeve 201. The output shaft 301 of the driver is provided with a positioning ridge 302 that matches the positioning groove 202 and is embedded in the positioning groove 202. A retaining nut 303 is provided at the end of the output shaft 301 to secure the movable disc 2 to the output shaft 301.
[0027] One side of the movable disc 2 is provided with shearing teeth 203, and the other side of the movable disc 2 is provided with multiple boost blades 204, which are installed near the connecting cavity 102. The boost blades 204 are integrally formed with the movable disc 2, with the other side of the movable disc 2 partially protruding outward to form the boost blades 204. The boost blades 204 are arc-shaped and arranged centrifugally around the axis of the movable disc 2. A retaining ring 205 is provided on the other side of the movable disc 2, located on the periphery of the shaft sleeve 201, and one end of the boost blade 204 is connected to the retaining ring 205.
[0028] The end surface of the pump body 1 near the shearing chamber 101 is connected to a fixed disk 4, which seals the opening of the shearing chamber 101. A feed inlet 401 is provided in the center of the fixed disk 4. Fixed shear teeth 402 are provided on the side of the fixed disk 4 near the movable disk 2. The fixed shear teeth 402 engage with the movable shear teeth 203. A discharge port (not shown) is provided on the sidewall of the pump body 1 located near the shearing chamber 101. Both the feed inlet 401 and the discharge port are interconnected with the shearing chamber 101.
[0029] When the extended-range shear pump disclosed in the present application is in operation, the output shaft 301 of the motor 3 drives the movable disc 2 to rotate, and the movable shearing teeth 203 of the movable disc 2 and the fixed shearing teeth 402 of the fixed disc 4 perform a shearing action on each other. The material enters from the feed port 401, is sheared by the fixed shearing teeth 402 of the fixed disc 4 and the movable shearing teeth 203 of the movable disc 2, and then enters the shearing chamber 101, and is then discharged from the discharge port. During this process, under the action of the booster blades 204 of the movable disc 2, a centrifugal airflow is formed in the shearing chamber 101, thereby increasing the pressure in the shearing chamber 101 and achieving an extended-range effect on the material conveying.
[0030] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
