Description

Technical Field

[0001] This utility model relates to the technical field of crushing and screening devices, and in particular to a crushing and screening device for γ-aminobutyric acid. Background Technology

[0002] γ-Aminobutyric acid (GABA) is an amino acid with physiological effects such as improving sleep quality and lowering blood pressure. The preparation of GABA requires pulverization and sieving according to different particle sizes. Various pulverizing and sieving devices have been proposed in the prior art. For example, Chinese utility model patent CN219519045U discloses a pulverizing device with a sieving function. This device includes an outer casing with a feed inlet on one side of the top of the casing. A drive motor is fixedly connected to the middle of the top of the outer casing. The output end of the drive motor extends to the bottom of the outer casing and is fixedly connected to a connecting rod. Pulverizing rods are fixedly connected to both sides of the connecting rod. A partition plate is fixedly connected to the upper end between the two sides inside the outer casing, and a sieving plate is fixedly connected to the lower end between the two sides inside the outer casing. This pulverizing device with a sieving function can achieve stable sieving through the cooperation of the auxiliary sieving structure and the sieving plate, classifying materials according to different conditions. The cooperation of the push rod, fixed plate, and sliding plate can clean the material accumulated on the surface of the sieving plate.

[0003] However, the above-mentioned crushing and screening device directly conveys the crushed material to the screening plate for two-stage screening after crushing the material rack. This means that the unqualified material that passes through the screening plate must be collected before it can be crushed again, which is more complicated and not conducive to improving work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a γ-aminobutyric acid (GABA) pulverizing and sieving device that allows GABA powder with unqualified particle size to be directly crushed and pulverized repeatedly without entering the sieving stage, resulting in high working efficiency.

[0005] This utility model discloses a γ-aminobutyric acid (GABA) pulverizing and sieving device, comprising a base plate, a feeding hopper, and a frame. The frame is mounted on the base plate, and the feeding hopper is mounted on the frame. It also includes a mounting frame, a roller, a sluice gate, a sieve plate, and a sieve cylinder. The mounting frame is mounted on the frame, and the roller is rotatably mounted on the mounting frame. One end of the roller has a feed inlet, and the output end of the feeding hopper extends into the feed inlet of the sluice gate. The other end of the roller has a discharge outlet, which is lower than the feed inlet. The sieve plate is mounted on the discharge outlet and has sieve holes (number 1). The sluice gate is rotatably mounted inside the roller, and a pulverizing gap is formed between the lower surface of the sluice gate and the lower inner surface of the roller. The sieve cylinder is concentrically mounted outside the output outlet of the roller. Multiple sieve holes (numbers 2, 3, to N) are provided on the outer wall of the sieve cylinder. The sieve holes (numbers 2, 3, to N) gradually move away from the sieve plate, and their diameters gradually increase, with the diameter of sieve hole N being larger than that of sieve hole 1. During operation, GABA powder is added to the feeding hopper, and the powder is pulverized and sieved through the output end of the feeding hopper. Gamma-aminobutyric acid (GABA) is added to the feed inlet of the drum and falls onto the lower inner surface of the drum. The drum rotates on the mounting frame, and the rollers and drum rotate relative to each other. When the GABA passes through the crushing gap between the rollers and drum, it is crushed. Because the discharge port of the drum is lower than the feed inlet, the GABA powder gradually flows towards the discharge port of the drum and undergoes multiple crushing processes. When the GABA powder reaches the sieve plate, the GABA powder smaller than the first sieve hole passes through the first sieve hole and enters the sieve cylinder. The GABA powder intercepted by the sieve plate continues to be crushed by the rollers and drum. The sieve cylinder rotates with the drum, causing the GABA powder to tumble and be conveyed backward in the sieve cylinder. The GABA powder is screened in multiple stages as it passes through the second, third, and Nth sieve holes, and the particle diameter gradually increases. Compared with the existing technology, GABA powder with unqualified particle size is directly repeatedly crushed without entering the screening stage, which simplifies the operation and increases the work efficiency.

[0006] Preferably, the width of the crushing gap between the lower surface of the roller and the lower inner surface of the drum gradually decreases from the feed inlet to the discharge outlet of the drum; by setting a gradually decreasing crushing gap, the γ-aminobutyric acid powder is gradually crushed and reduced, thereby improving the crushing effect.

[0007] Preferably, it also includes a rotating shaft, gears, and a gear ring. The rotating shaft is located in the middle of the roller and is rotatably mounted on the frame. The gears are concentrically mounted on the rotating shaft, and the gear ring is mounted on the feed inlet of the roller, meshing with the gears. When the roller rotates, it drives the rotating shaft and gears to rotate. The gears meshing with the gear rings drive the rollers to rotate, thereby causing the rollers and the drum to rotate relative to each other. This results in the γ-aminobutyric acid powder passing through the crushing gap between the rollers and the drum being crushed and pulverized, ensuring stable and reliable operation.

[0008] Preferably, it also includes a motor, a driving wheel, a driven wheel, and a transmission belt. The motor is mounted on the frame, and the driving wheel is concentrically mounted on the output shaft of the motor. The driven wheel is concentrically mounted on the rotating shaft, and the transmission belt is fitted onto the driving wheel and the driven wheel. The motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission belt. The driven wheel drives the rotating shaft and the roller to rotate, and the rotating shaft drives the gear to rotate. The gear drives the drum to rotate through the gear ring, thereby realizing the drive of the drum and the roller, which has good practicality.

[0009] Preferably, the mounting frame includes two wheel frames and multiple track wheels. The two wheel frames are mounted on the machine frame and are located on both sides of the drum. Multiple track wheels are rotatably mounted on each of the two wheel frames. Multiple annular tracks are installed on the outer wall of the drum, and the multiple track wheels are tactilely connected to the multiple annular tracks of the drum. The two wheel frames and multiple track wheels provide rolling support for the drum, allowing the drum to rotate and be mounted on the machine frame.

[0010] Preferably, it also includes a piston plate and a push rod. The piston plate is slidably installed in the sieve cylinder, and the edge of the piston plate slides in contact with the inner wall of the sieve cylinder. One end of the push rod is rotatably connected to the piston plate, and the other end of the push rod extends out of the outside of the sieve cylinder. The push rod drives the piston plate to move away from the sieve plate in the sieve cylinder, so that the γ-aminobutyric acid powder in the sieve cylinder can fully contact the multiple sieve holes 2, 3, and N in sequence, thereby improving the sieving accuracy.

[0011] Preferably, it also includes a push cylinder, the fixed end of which is mounted on the frame, and the piston rod of the push cylinder is connected to the push rod; the piston rod of the push cylinder extends and retracts to drive the push rod to move, so that the push rod drives the piston plate to move in the screen cylinder, thereby driving the piston plate and making it practical.

[0012] Compared with the prior art, the advantages of this utility model are: γ-aminobutyric acid powder with unqualified particle size can be directly crushed and pulverized repeatedly without entering the sieving stage, which simplifies the operation and improves work efficiency.

Detailed Implementation

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, a γ-aminobutyric acid (GABA) pulverizing and screening device includes a base plate 1, a feeding hopper 2, and a frame 3. The frame 3 is mounted on the base plate 1, and the feeding hopper 2 is mounted on the frame 3. It also includes a mounting frame 4, a drum 5, a roller 6, a screen plate 7, and a screen cylinder 8. The mounting frame 4 is mounted on the frame 3. The drum 5 is rotatably mounted on the mounting frame 4. One end of the drum 5 has a feed inlet, and the output end of the feeding hopper 2 extends into the feed inlet of the roller 6. The other end of the drum 5 has a discharge outlet, and the output outlet of the drum 5 is lower than the feed inlet. The screen plate 7 is mounted on the discharge outlet and has a screen hole. The roller 6 is rotatably mounted inside the drum 5, and a pulverizing gap is formed between the lower surface of the roller 6 and the lower inner surface of the drum 5. The screen cylinder 8 is concentrically mounted on the drum 5. On the outer side of the output port, multiple screen holes 2, 3 to N are provided on the outer wall of the screen cylinder 8. The screen holes 2, 3 to N gradually move away from the screen plate 7, and the apertures of the screen holes 2, 3 to N gradually increase. The aperture of screen hole N is larger than that of screen hole 1. A crushing gap is provided between the lower surface of the roller 6 and the lower inner surface of the drum 5. The width of the gap gradually decreases from the feed port to the discharge port of the drum 5. The mounting frame 4 includes two wheel frames 16 and multiple track wheels 17. The two wheel frames 16 are mounted on the frame 3 and are located on both sides of the drum 5. Multiple track wheels 17 are rotatably mounted on both wheel frames 16. Multiple annular tracks are installed on the outer wall of the drum 5, and the multiple track wheels 17 are tumblingly connected to the multiple annular tracks of the drum 5.

[0023] Two wheel frames 16 and multiple track wheels 17 provide rolling support for the drum 5, allowing the drum 5 to rotate on the frame 3. During operation, γ-aminobutyric acid (GABA) powder is added to the feeding hopper 2. The GABA is then fed into the inlet of the drum 5 through the output end of the feeding hopper 2 and falls onto the lower inner surface of the drum 5. The drum 5 rotates on the mounting frame 4, and the roller 6 rotates relative to the drum 5. When the GABA passes through the crushing gap between the roller 6 and the drum 5, it is crushed. Because the outlet of the drum 5 is lower than the inlet, the GABA powder gradually flows towards the outlet of the drum 5 and undergoes multiple crushing processes. This is achieved by setting a gradually decreasing crushing gap. The γ-aminobutyric acid (GABA) powder is gradually crushed and pulverized. When the GABA powder reaches the sieve plate 7, the GABA powder smaller than the first sieve hole passes through the first sieve hole of the sieve plate 7 and enters the sieve cylinder 8. The GABA powder intercepted by the sieve plate 7 continues to be crushed and pulverized by the rollers 6 and the drum 5. The sieve cylinder 8 rotates with the drum 5, so that the GABA powder tumbles in the sieve cylinder 8 and is conveyed backward. The GABA powder is screened in multiple stages as it passes through the second sieve hole, the third sieve hole and the Nth sieve hole, and the particle diameter gradually increases. Compared with the existing technology, the GABA powder with unqualified particle size is directly crushed and pulverized repeatedly without entering the screening stage, which simplifies the operation.

[0024] Example 2

[0025] like Figure 4 and Figure 5 As shown, based on Embodiment 1, it also includes a rotating shaft 9, a gear 10, and a gear ring 11. The rotating shaft 9 is set in the middle of the roller 6 and is rotatably mounted on the frame 3. The gear 10 is concentrically mounted on the rotating shaft 9, and the gear ring 11 is mounted on the feed inlet of the roller 5 and meshes with the gear 10. It also includes a motor 12, a driving wheel 13, a driven wheel 14, and a transmission belt 15. The motor 12 is mounted on the frame 3, and the output shaft of the motor 12 is concentrically mounted on the driving wheel 13. The driven wheel 14 is concentrically mounted on the rotating shaft 9, and the transmission belt 15 is fitted on the driving wheel 13 and the driven wheel 14.

[0026] Motor 12 drives drive wheel 13 to rotate, drive wheel 13 drives driven wheel 14 to rotate via transmission belt 15, driven wheel 14 drives shaft 9 and roller 6 to rotate, and roller 6 drives shaft 9 and gear 10 to rotate when roller 6 rotates, gear 10 meshes with gear ring 11 to drive drum 5 to rotate, so that roller 6 and drum 5 rotate relative to each other, so that the γ-aminobutyric acid powder passing through the crushing gap between roller 6 and drum 5 is crushed and pulverized, and the drive is stable and reliable.

[0027] Example 3

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, based on Embodiment 1, it also includes a piston plate 18 and a push rod 19. The piston plate 18 is slidably installed in the screen cylinder 8, and the edge of the piston plate 18 is in sliding contact with the inner wall of the screen cylinder 8. One end of the push rod 19 is rotatably connected to the piston plate 18, and the other end of the push rod 19 extends out of the screen cylinder 8. It also includes a push cylinder 20, the fixed end of the push cylinder 20 is installed on the frame 3, and the piston rod of the push cylinder 20 is connected to the push rod 19.

[0029] The piston rod of the push cylinder 20 extends and retracts, driving the push rod 19 to move. This causes the push rod 19 to move the piston plate 18 away from the sieve plate 7 in the sieve cylinder 8, thereby ensuring that the γ-aminobutyric acid powder in the sieve cylinder 8 comes into full contact with the multiple sieve holes 2, 3, and N in sequence, thus improving the sieving accuracy.

[0030] like Figures 1 to 6 As shown, this utility model discloses a γ-aminobutyric acid (GABA) pulverizing and sieving device. During operation, GABA powder is first added to the feeding hopper 2. The GABA is then fed into the inlet of the drum 5 through the output end of the feeding hopper 2 and falls onto the lower inner surface of the drum 5. Next, the motor 12 drives the drive wheel 13 to rotate. The drive wheel 13 drives the driven wheel 14 to rotate via the transmission belt 15. The driven wheel 14 drives the rotating shaft 9 and the roller 6 to rotate. The rotating shaft 9 drives the gear 10 to rotate, and the gear 10 drives the drum 5 to rotate via the gear ring 11. The drum 5 rotates on the mounting frame 4, and the roller 6 and drum 5 rotate relative to each other. When the GABA passes through the pulverizing gap between the roller 6 and the drum 5, it is crushed and pulverized. Because the outlet of the drum 5 is lower than the inlet, the GABA powder gradually moves towards the drum. The γ-aminobutyric acid (GABA) powder flows through the outlet of 5 and undergoes multiple crushing processes. When the GABA powder reaches the sieve plate 7, the GABA powder smaller than the first sieve hole passes through the first sieve hole of the sieve plate 7 and enters the sieve cylinder 8. The GABA powder intercepted by the sieve plate 7 continues to be crushed by the rollers 6 and the drum 5. The sieve cylinder 8 rotates with the drum 5, causing the GABA powder to tumble and be conveyed backward in the sieve cylinder 8. Finally, the piston rod of the push cylinder 20 extends and retracts, driving the push rod 19 to move. This causes the push rod 19 to drive the piston plate 18 to move away from the sieve plate 7 in the sieve cylinder 8, so that the GABA powder in the sieve cylinder 8 comes into full contact with the multiple sieve holes 2, 3, and N in sequence. The GABA powder is multi-stage sieved as it passes through the sieve holes 2, 3, and N, and the particle diameter gradually increases.

[0031] The main functions achieved by this utility model are:

[0032] 1. Gamma-aminobutyric acid powder with unqualified particle size can be directly crushed and pulverized without entering the sieving stage, which simplifies the operation and increases work efficiency.

[0033] 2. By setting a gradually decreasing grinding gap, the γ-aminobutyric acid powder is gradually crushed and reduced in size, thereby improving the grinding effect;

[0034] 3. The piston plate 18 is driven by the push rod 19 to move away from the sieve plate 7 in the sieve cylinder 8, so that the γ-aminobutyric acid powder in the sieve cylinder 8 can fully contact the multiple sieve holes 2, multiple sieve holes 3 to multiple sieve holes N in sequence, thereby improving the sieving accuracy.

[0035] The γ-aminobutyric acid (GABA) pulverizing and screening device of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The feeding hopper 2, drum 5, roller 6, sieve plate 7, sieve cylinder 8, rotating shaft 9, gear 10, gear ring 11, motor 12, driving wheel 13, driven wheel 14, transmission belt 15, wheel frame 16, track wheel 17, piston plate 18, and push cylinder 20 of this γ-aminobutyric acid pulverizing and screening device are commercially available.
