Description

Technical Field

[0001] The utility model relates to the technical field of phosphate food additive processing, in particular to a phosphate food additive product grading device. Background Art

[0002] Phosphate is an important product series in the inorganic salt industry. Food-grade phosphate is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid, which is a very important substance in inorganic chemistry, biochemistry and biogeochemistry. Phosphate ore (fluoroapatite or chloroapatite) naturally existing in the earth's crust is the main raw material for phosphorus, phosphoric acid and phosphate. The smelting of phosphate ore can produce yellow phosphorus, the combustion and hydration of yellow phosphorus can produce phosphoric acid, the purification of phosphoric acid can produce food phosphoric acid, and the synthesis of food phosphoric acid can produce food-grade phosphate (i.e. phosphate food additive). Phosphate can be divided into orthophosphate and condensed phosphate: Phosphates used in food processing are usually sodium salts, calcium salts, potassium salts, and iron and zinc salts as nutritional enhancers. There are more than 30 varieties of commonly used food-grade phosphates. Sodium phosphate is the main consumption type of food phosphate at home and abroad. With the development of food processing technology, the consumption of potassium phosphate is also increasing year by year. Phosphates need to be screened during processing. The traditional method mostly uses mesh screens, which are inefficient. Therefore, many manufacturers on the market currently use drum screening machines for screening. However, drum screening machines have large centrifugal force and will produce a lot of dust.

[0003] In this regard, a Chinese utility model patent with authorization notification number CN205413572U discloses a rotary screening device, which includes an outer rotary screen, a hopper, a bracket, a base, an inner rotary screen, a transmission shaft, a motor, a first discharge port, a second discharge port and a third discharge port; the outer rotary screen and the inner rotary screen are both installed on the transmission shaft and rotate with the transmission shaft, the transmission shaft is connected to the output shaft of the motor, the motor is fixedly installed on the left side of the bracket, a hopper is installed on the right side of the bracket, the bottom end of the bracket is fixedly installed on the base, a first discharge port is provided on the left side of the bracket and is located below the motor, a second discharge port is provided on the bracket and is located on the right side of the first discharge port, and a third discharge port is provided in the middle of the bottom of the outer rotary screen and is located on the right side of the second discharge port.

[0004] The rotary screening device is equipped with baffles and dust-proof brackets to avoid large amounts of dust. However, the centrifugal force of the drum is large during use, and the material inside will stick to the inner wall of the drum under the action of centrifugal force. The material may contaminate the inner wall of the drum, which may easily cause the screen to become clogged and affect the screening efficiency.

[0005] To solve the above problems, a Chinese patent with publication number CN216728114U discloses a drum-type rotary screening device for phosphates, in which a fixed ring is arranged on the outside of the drum, and arc-shaped teeth are evenly arranged on the surface of the fixed ring. When the drum rotates, a plurality of arc-shaped teeth will move on the striking arc plate on the fixed rod, thereby causing the striking arc plate to deform. During the deformation process, the fixed ring will be struck, thereby causing the drum to vibrate. In this way, when the inner wall of the drum is contaminated with material, the material will leave the inner wall of the drum due to the shock force, thereby avoiding the situation where the material accumulates and sticks to the inner wall of the drum, thereby avoiding the situation where the material blocks the screening holes.

[0006] Although the above-mentioned prior art can prevent the situation where the material blocks the screening holes, it is unable to grade and screen the phosphate food additives, and cannot finely classify them into different levels according to their particle sizes to meet the needs of different food production.

[0010] The other side of the grading bin is fixedly connected to an air inlet pipe fixedly connected to the wind conveying device, the inner wall of the grading bin is rotatably connected to a built-in separation drum, and a first screening inclined plate with one end rotatably connected to the inner wall of the grading bin is provided below the built-in separation drum.

[0012] A further improvement of the technical solution of the utility model is that a material discharge inclined plate is arranged below the first screening inclined plate, and both ends of the material discharge inclined plate are fixedly connected to the inner wall of the grading bin.

[0017] A further improvement of the technical solution of the utility model is that: the number of the vibration springs is two groups, and the two groups of vibration springs are symmetrically distributed on the bottom surface of one end of the first screening inclined plate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] Example 1

[0029] like Figure 1-4 As shown, the utility model provides a phosphate food additive product grading device, including a grading bin 1, a protective cover 2, a wind conveying device 6 and a vibrator 15, a grading air outlet pipe 3 is fixedly connected to one side of the top of the grading bin 1, and a collecting cloth bag 4 is fixedly sleeved on one end of the grading air outlet pipe 3.

[0030] The other side of the grading bin 1 is fixedly connected to an air inlet pipe 5 which is fixedly connected to a wind conveying device 6. The inner wall of the grading bin 1 is rotatably connected to a built-in separation drum 8. A first screening inclined plate 10 having one end rotatably connected to the inner wall of the grading bin 1 is provided below the built-in separation drum 8.

[0031] One end of the first screening inclined plate 10 is fixedly connected to a collecting box 7, which is located on the outer wall of the grading bin 1. A collecting breathable cloth 12 is fixedly connected to the side of the collecting box 7 away from the grading bin 1. A vibration spring 13 is fixedly connected to the bottom surface of one end of the first screening inclined plate 10.

[0032] Example 2

[0033] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, a material discharge inclined plate 11 is arranged below the first screening inclined plate 10, and both ends of the material discharge inclined plate 11 are fixedly connected to the inner wall of the grading bin 1.

[0034] One end of the vibration spring 13 away from the first screening inclined plate 10 is fixedly connected to the positioning plate 14 , and one end of the first screening inclined plate 10 close to the vibration spring 13 is movably connected to the inner wall of the grading bin 1 .

[0035] The vibrator 15 is located at the bottom surface of one end of the first screening inclined plate 10, and one side of the vibrator 15 is fixedly connected to the inner wall of the grading bin 1. Under the impact vibration of the vibrator 15, the first screening inclined plate 10 will exert the impact force on the vibration spring 13, and the first screening inclined plate 10 is buffered by the deformation of the vibration spring 13, which can assist the vibration of the first screening inclined plate 10 and avoid the problem of clogging of the screen holes thereon.

[0036] One side of the protective cover 2 is rotatably connected to the top of the grading bin 1 through a hinge, and a support leg is fixedly connected to the bottom surface of the grading bin 1. There are two groups of vibration springs 13, and the two groups of vibration springs 13 are symmetrically distributed on the bottom surface of one end of the first screening inclined plate 10.

[0037] The working principle of the phosphate food additive product grading device is described in detail below.

[0038] like Figure 1-4 As shown, when in use, the protective cover 2 is opened, and then the material is placed in the built-in separation drum 8, and then the protective cover 2 is closed, and the built-in separation drum 8 is adjusted to start rotating to screen the material therein, and then the wind conveying device 6 is started to generate wind to blow to the built-in separation drum 8, and a part of the material screened out of the built-in separation drum 8 will enter the graded air outlet duct 3 along the guidance of the air guide arc plate 9 under the blowing of the wind, and enter the collecting bag 4 to be collected.

[0039] The other part of the material particles with larger particles that have not been blown into the collecting bag 4 by the wind will fall on the first screening inclined plate 10. At the same time, the vibrator 15 is started to impact one end of the first screening inclined plate 10, so that the first screening inclined plate 10 vibrates and the material particles thereon are screened again. A part of the material particles smaller than the sieve holes of the first screening inclined plate 10 will fall into the unloading inclined plate 11 and be discharged from the grading bin 1, while the material particles larger than the sieve holes of the first screening inclined plate 10 will enter the collecting box 7 for temporary storage under the oblique diversion of the first screening inclined plate 10.

[0040] The first screening inclined plate 10 will exert impact force on the vibration spring 13 under the impact vibration of the vibrator 15, and the deformation effect of the vibration spring 13 can be used to cushion the first screening inclined plate 10, while assisting the vibration of the first screening inclined plate 10 and avoiding the problem of blockage of the screen holes thereon.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
