Description

TECHNICAL FIELD

[0001] The utility model relates to melon seed production and processing field, specifically is a melon seed impurity removal device. BACKGROUND

[0002] In the roasting process of melon seeds, ensuring the purity of melon seeds is crucial to guarantee product quality. Therefore, removing impurities in melon seeds with the help of impurity removal equipment before and after roasting becomes a key link to improve the overall quality of melon seeds.

[0003] At present, most impurity removal devices use a combination of wind power and screen vibration to remove impurities from melon seeds (such as the technical solution disclosed in patent application No. CN202421062647.2). However, in actual production and application, this impurity removal method has obvious drawbacks, especially when dealing with roasted melon seeds. Dust or smoke particles mixed in the melon seeds will be blown out with the wind and vibration of the screen. This not only pollutes the processing environment, affects the air quality of the workshop, and is harmful to the health of the operators, but also may cause the surrounding work area to be covered with dust, affecting the normal operation and service life of other equipment. In addition, the melon seed conveying path of this impurity removal device is consistent with the wind direction, so it cannot effectively remove the empty shells mixed in the melon seeds during the impurity removal process, affecting the impurity removal quality. SUMMARY

[0004] Therefore, in order to solve the above problems, the utility model provides a melon seed impurity removal device. The impurity removal device is provided with an impurity removal cylinder in the impurity removal cavity, and a tumbling feeding mechanism is used to move and tumble the melon seeds in the impurity removal cylinder. This can remove impurities in a relatively closed environment, and the exhaust pipe and several discharge cylinders are arranged to facilitate the discharge of smoke and various impurities and melon seeds after impurity removal. This improves the quality of melon seed impurity removal while ensuring the processing environment. In addition, the air inlet on the side of the bottom of the impurity removal cylinder can blow out the empty shells in the melon seeds, thereby discharging the empty shells separately and improving the quality of impurity removal.

[0005] The utility model is implemented as follows: a melon seed impurity removal device is provided, which includes an impurity removal cavity, an impurity removal cylinder placed in the cavity, and a tumbling feeding mechanism.

[0006] A feed hopper is arranged above the impurity removal cavity and communicates with the impurity removal cavity.

[0032] As described in the background, the existing melon seed impurity removal device usually combines a vibrating screen and a fan to remove impurities. However, in the impurity removal process, the smoke dust mixed in the melon seeds will be scattered outward under the double action of screen vibration and fan blowing, which seriously affects the external processing environment, and the existing impurity removal device cannot effectively remove the empty shells mixed in the melon seeds.

[0033] Based on the above reasons, to solve the above problems, the utility model provides the following technical scheme:

[0034] Embodiment 1,

[0035] Please refer to the drawings Figure 1 ~Appendix Figure 5 A melon seed impurity removal device, comprising an impurity removal cavity 2 placed on a rack 1 and having an impurity removal cylinder 12 placed inside;

[0036] A feed hopper 3 is arranged above the impurity removal cavity 2 and communicates with the impurity removal cavity 2;

[0037] A turning and feeding mechanism is rotatably arranged in the impurity removal cylinder 12 to uniformly push the melon seeds from the feed hopper 3 into the impurity removal cylinder 12 for impurity removal;

[0038] A plurality of discharge cylinders are communicatively arranged on the impurity removal cavity 2 and correspond to a plurality of discharge ports on the impurity removal cylinder 12;

[0039] An exhaust pipe 4 is arranged above the impurity removal chamber 2 to exhaust smoke generated during impurity removal.

[0040] An air inlet 10 is arranged on the impurity removal chamber 2 to correspond to the discharge cylinder to blow out the empty shells in the melon seeds.

[0041] In the embodiment, the impurity removal cylinder 12 is arranged in the impurity removal chamber 2 and fixed at both ends to the inner wall of the impurity removal chamber 2, the feed hopper 3 is arranged above the impurity removal chamber 2 outside one end of the impurity removal cylinder 12, the turnover feeding mechanism is arranged in the impurity removal chamber 2 and the impurity removal cylinder 12 and rotates, the first discharge hole 14 is uniformly arranged on the outer end of the impurity removal cylinder 12 close to the feed hopper 3, the second discharge hole 13 is arranged on the bottom of the other end of the impurity removal cylinder 12, and the third discharge hole is formed at the other end of the impurity removal cylinder 12.

[0042] In the embodiment, the discharge cylinder includes a first discharge cylinder 8, a second discharge cylinder 9 and a third discharge cylinder 11, the first discharge cylinder 8 corresponds to the first discharge hole 14, the second discharge cylinder 9 corresponds to the second discharge hole 14, and the third discharge cylinder 11 corresponds to the third discharge hole.

[0043] In the embodiment, to facilitate the discharge of the empty shells mixed in the melon seeds, please refer to the attached Figure 4 The second discharge hole 13 is a groove-shaped hole for discharging the melon seeds, the second discharge hole 13 is arranged on one side of the bottom of the other end of the impurity removal cylinder 12, the second discharge cylinder 9 is in the shape of a chevron, the first end is communicated with the impurity removal chamber 2, the second end is arranged on one side below and corresponds to the second discharge hole 13, and the third end is arranged on the other side below, the air inlet 10 is arranged above the second end of the second discharge cylinder 9, and the positive pressure air is introduced into the second discharge cylinder 9 through the air inlet 10 to blow the empty shells in the melon seeds into the third end and discharge.

[0044] In use, the air inlet 10 is connected to an external positive pressure air source beforehand, and the exhaust pipe 4 is connected to an external pipeline (a negative pressure air source can be preset to extract smoke and dust). Then, the drive motor 6 is started to rotate the rotating rod 15, and the sunflower seeds to be cleaned are poured into the feed hopper 3. Under the action of gravity, the sunflower seeds fall into the gap between the feeding blades 17 of the rotating rod 15. As the rotating rod 15 rotates, the sunflower seeds enter the impurity removal cylinder 12. Under the action of the rotation of the turning blades 18, the sunflower seeds are turned upward. Smaller impurities (such as stones and gravel) pass through the first discharge hole 14, fall into the first discharge cylinder 8 and are discharged. During the turning, the sunflower seeds are produced. The generated smoke and dust are discharged directly from the exhaust pipe 4, while larger impurities and sunflower seeds continue to move in the impurity removal cylinder 12. When they reach the second discharge hole 13, the sunflower seeds and shells pass through the second discharge hole 13 and fall off (because the sunflower seeds and shells are the same size but different in weight). Under the blowing of the positive pressure air source at the air inlet 10, the sunflower seed shells are blown out to the third channel of the second discharge cylinder 9, while the sunflower seeds, due to their greater weight, are discharged directly from the second channel, thus separating the sunflower seeds and shells. Finally, the impurities that do not pass through the second discharge hole 13 continue to move in the impurity removal cylinder 12 and fall from the end into the third discharge cylinder 11, thus completing the entire impurity removal process.

[0045] During the process of positive pressure air being blown out of the air inlet 10 and exhaust air being discharged from the exhaust pipe 4, positive pressure air is introduced into the impurity removal chamber through the air inlet 10, while negative pressure air is introduced into the impurity removal chamber through the exhaust pipe 4. This is because the feed hopper 3 and the impurity removal chamber 2 are blocked by the feeding blades 17 (see attached). Figure 5 This means that the airflow inside the impurity removal chamber 2 will not flow back into the feed hopper 3, thereby preventing dust from flowing back into the feed hopper 3 and overflowing outward. Therefore, the airflow inside the impurity removal chamber 2 is only through the air inlet 10, the exhaust pipe 4, and multiple discharge cylinders. That is, the discharge cylinders (including the first discharge cylinder 8, the second discharge cylinder 9, and the third discharge cylinder 11) may introduce positive or negative pressure air into the impurity removal chamber.

[0046] When positive pressure air is introduced into the impurity removal chamber through the discharge cylinder, it indicates that dust will not be discharged from the discharge cylinder. The dust mixed in with the sunflower seeds will float upward and be discharged from the exhaust pipe 4 when it is turned over in the impurity removal cylinder 12.

[0047] When the negative pressure air is introduced into the dedusting cavity through the discharge cylinder, part of the air will be discharged from the first discharge cylinder 8, the second end or the third end of the second discharge cylinder 9, and the third discharge cylinder 11 through the dedusting cylinder 12. Because the melon seeds will float upward during the conveying and tumbling process in the dedusting cylinder 12, the first discharge cylinder 8 is arranged below the dedusting cylinder 12, so that most of the dust is directly discharged through the air outlet pipe 4 above. The second discharge cylinder 9 is far away from the air outlet pipe 4, so that the melon seeds conveyed to the second discharge cylinder 9 have almost no dust. In order to further ensure the dedusting environment, a soft container (such as a pocket cloth bag) can be sleeved on the first discharge cylinder 8, the second discharge cylinder 9 or the third discharge cylinder 11 to prevent dust overflow, and the receiving of the melon seeds can also be realized. This dedusting mode can effectively prevent the dust from spreading outward, ensure the dedusting environment, and effectively separate various impurities in the melon seeds.

[0048] Embodiment 2,

[0049] Please refer to the accompanying Figure 5 , based on the basis of embodiment 1, in order to drive the melon seeds to be uniformly conveyed into the dedusting cylinder 12 for dedusting, and to tumble the melon seeds in the dedusting cylinder 12, so as to facilitate the separation of impurities. The tumbling and feeding mechanism comprises a rotating rod 15 and a driving assembly for rotating the rotating rod 15. The rotating rod 15 penetrates the dedusting cavity 2 and the dedusting cylinder 12. Feeding blades 17 are arranged outside the corresponding positions of the rotating rod 15 and the feeding hopper 3. The feeding blades 17 are spiral blades. Tumbling blades 18 are arranged outside the rotating rod 15 in the dedusting cylinder 12.

[0050] In this embodiment, the driving assembly comprises a driving motor 6 and a transmission mechanism 16. The transmission mechanism 16 is arranged in the transmission box 7 outside the dedusting cavity 2 and is connected to one end of the rotating rod 15. The other end of the transmission mechanism 16 is connected to the driving motor 6.

[0051] Embodiment 3,

[0052] Please refer to the accompanying Figure 1 and the accompanying Figure 2 , based on the basis of embodiment 1, in order to facilitate the cleaning of the dedusting cylinder and avoid the melon seeds being stuck on the discharge hole to affect the quality of subsequent dedusting, a cleaning door 5 is further arranged on the dedusting cavity 2 to facilitate the cleaning of the inside.
