Description

Technical Field

[0001] The invention belongs to the technology of removing impurities from dried fruits, and in particular relates to a device for sucking and separating dust and fruit stems from dried fruits. Background Art

[0002] During the rough processing of dried fruits, the dried fruits are mixed with impurities such as dust and fruit stems. In order to separate the dried fruits from impurities such as dust and fruit stems, one of the commonly used methods is to use a negative pressure bellows system to remove impurities. The main principle of the negative pressure bellows system is to use a negative pressure fan to form a negative pressure in the bellows. When the mixture of dried fruits, dust and fruit stems is thrown into the bellows, the negative pressure in the bellows can suck the lighter fruit stems and dust to separate them from the dried fruits.

[0003] At present, the separated fruit stalks and dust mixture are usually discharged directly to a designated location as impurities. Through continuous practice, it has been found that fruit stalks, as a by-product of crops, are rich in nutrients such as cellulose, minerals and vitamins. These nutrients play a very important role in the growth, development and health of animals. In particular, the cellulose in them can promote the functioning of the animal's digestive system, help prevent constipation and other digestive problems, and maintain the animal's digestive health. Therefore, if the fruit stalks are used as feed, it can not only reduce feed costs and improve economic benefits, but also reduce resource waste and environmental burdens, which is in line with the principle of sustainable development and has a positive effect on environmental protection.

[0004] Based on the above analysis, the present application designs a device for extracting and separating dust and stems of dried fruits. Summary of the invention

[0005] The purpose of the present invention is to provide a dried fruit dust and stalk suction separation device to solve the problem that the existing separated stalk and dust mixture is directly discharged as impurities, resulting in the ineffective utilization of dried fruit by-product resources and a large amount of dust polluting the environment.

[0006] The present application provides a device for suctioning and separating dust and fruit stems of dried fruits, comprising a separation mechanism and a cyclone dust removal mechanism, wherein the separation mechanism comprises a separation bin, which is provided with a feed port near the top and a discharge port at the bottom, and wherein a partition plate extending toward the discharge port is provided in the separation bin, wherein the partition plate divides the separation bin into a first air flow channel and a second air flow channel, wherein the first air flow channel and the second air flow channel constitute a cyclonic air flow path, wherein the first air flow channel is directly connected to the feed port of the separation bin; and the cyclone dust removal mechanism is connected to the second air flow channel on the separation bin via a negative pressure fan mechanism.

[0007] As a preferred embodiment of the present application, the separation bin is a prism structure that is wide at the top and narrow at the bottom. The top outer shell located at the top of the separation bin is an arc structure. The partition plate is an arc plate with the same curvature as the top outer shell. The first airflow channel is composed of the arc plate and the top outer shell and has an arc-shaped structure.

[0008] As a preferred solution of the present application, the docking port on the separation bin that is docked with the cyclone dust removal mechanism is close to the center of the arc plate.

[0009] As a preferred embodiment of the present application, a cover plate assembly is installed at the discharge port end, which is hinged to the discharge port end and includes a cover body and a counterweight body. The cover body can cover the discharge port under the action of the counterweight body and flip over and unload with the hinge point as the center when the weight of the material supported on the cover body is greater than the weight of the counterweight body.

[0010] As a preferred solution of the present application, the partition plate is arranged at one end of the separation bin close to the feed port.

[0011] As a preferred embodiment of the present application, the cyclone dust removal mechanism comprises a cyclone dust collector, and a discharge valve composed of a wind shut-off mechanism is installed at the discharge port end of the cyclone dust collector.

[0012] As a preferred embodiment of the present application, the negative pressure fan system includes a negative pressure fan, and the negative pressure fan is a high-pressure centrifugal fan.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0019] like Figure 1-2As shown, a dry fruit dust and fruit stem suction separation device provided by the present embodiment (the arrow in the figure indicates the direction of air flow), the device comprises a separation mechanism and a cyclone dust removal mechanism 7, the separation mechanism comprises a columnar separation bin 1, the separation bin 1 is provided with a feed port 2 on the side wall near the top, and a discharge port 3 at the bottom. It can be understood that the material entering the feed port 2 end should be a mixture of fruit stems and dust, and the material discharged from the discharge port 3 end is the fruit stem separated from the dust by gravity. At the same time, a partition plate extending to the discharge port 3 end is provided in the separation bin 1. 4, the partition plate 4 divides the separation bin 1 into a first airflow channel 5 and a second airflow channel 6, the first airflow channel 5 is directly connected to the feed port 2 of the separation bin 1, and the inlet end of the second airflow channel 6 is connected to the outlet end of the first airflow channel 5, that is, the second airflow channel 6 is indirectly connected to the feed port 2 of the separation bin 1 through the first airflow channel 5, and a cyclonic airflow path is formed by the first airflow channel 5 and the second airflow channel 6; the cyclone dust removal mechanism 7 is connected to the second airflow channel 6 on the separation bin 1 through the negative pressure fan mechanism 8, it can be understood that, The negative pressure fan mechanism 8 serves as a negative pressure power source to provide an adsorption force into the separation bin 1, and the adsorption force can be used to suck in the mixture of fruit stems and dust through the feed port 2 of the separation bin 1. Since the size of the adsorption force provided by the negative pressure fan mechanism 8 is preset, after the mixture enters the separation bin 1, the negative pressure airflow will carry the mixture along the cyclonic airflow path formed by the first airflow channel 5 and the second airflow channel 6. During the operation, when the mixture runs with the airflow to the intersection of the inlet end of the second airflow channel 6 and the outlet end of the first airflow channel 5, the fruit stems Since the adsorption force with a specific gravity greater than that at this position will fall to the discharge port 3 under the action of gravity and centrifugal force, and the dust with a lighter specific gravity will enter the cyclone dust removal mechanism 7 along with the airflow to separate the dust and the airflow, and the separated dust is discharged through the discharge port of the cyclone dust removal mechanism 7, and the separated clean airflow is discharged through the exhaust port of the cyclone dust removal mechanism 7. In this embodiment, the cyclone dust removal mechanism 7 includes a cyclone dust collector, and a discharge valve 13 composed of a blower is installed at the discharge port end of the cyclone dust collector. The discharge valve 13 composed of the blower can avoid the occurrence of dust.

[0020] In the present embodiment, the swirling airflow path formed by the partition plate 4 and the partition plate 4 and the side wall of the separation bin 1 provides, on the one hand, a critical point at which the fruit stems can fall. At this critical point, the specific gravity of the fruit stems is greater than the negative pressure adsorption force, thereby facilitating the automatic separation of the fruit stems under the dual effects of gravity and centrifugal force. On the other hand, the partition plate 4 prevents the fruit stems from directly entering the cyclone dust removal mechanism 7 through the negative pressure adsorption mechanism, thereby improving the separation efficiency of the separation bin 1.

[0021] It should be noted that in this embodiment, the width of the partition plate 4 should correspond to the internal width or length of the separation bin 1, which is specifically determined by its actual placement position. In this embodiment, the width of the partition plate 4 preferably corresponds to the internal width of the separation bin 1, that is, the partition plate 4 is located between the two side walls in the length direction of the separation bin 1, and the two side edges of the partition plate 4 are fixed to the two side walls in the width direction of the separation bin 1 by welding, and the front end is also fixed to the inner wall on one side in the length direction of the separation bin 1 by welding to avoid direct connection between the second airflow channel 6 and the feed port 2. It can be understood that the length of the partition plate 4 should be determined according to the negative pressure adsorption force or power provided by the negative pressure fan mechanism 8, so as to meet the purpose of satisfying that the negative pressure adsorption force at the intersection of the outlet end of the first airflow channel 5 and the inlet end of the second airflow is less than the specific gravity of most fruit stems.

[0022] In this embodiment, the negative pressure fan system includes a negative pressure fan and a connecting pipe, wherein the negative pressure fan is a high-pressure centrifugal fan of model 9-19-5A produced by Jiuzhou Puhui. The high-pressure centrifugal fan has a strong high-pressure capacity and is less affected by dust. When used in the rough processing process of dried fruits, its service life can at least be used to complete the processing of several thousand tons of dried fruits.

[0023] In this embodiment, the partition plate 4 is preferably arranged at one end of the separation bin 1 close to the feed port 2, and the front end of the partition plate 4 is located at the lower edge of the feed port 2. This makes it easy to set up, and on the other hand, being close to the feed port 2 can reduce the power requirement of the negative pressure fan mechanism 8.

[0024] In this embodiment, a cover plate assembly is installed at the discharge port 3 end of the separation bin 1, the cover plate assembly is hinged at the discharge port 3 end and includes a cover body 10 and a counterweight body 11, the cover plate and the counterweight body 11 form a seesaw structure with the hinge point 12 as the center, the cover body 10 can be covered at the discharge port 3 under the action of the counterweight body 11 and when the weight of the material supported on the cover body 10 is greater than the weight of the counterweight body 11, it is turned over and unloaded with the hinge point 12 as the center, and the discharge port 3 end of the separation bin 1 can be covered by the cover plate assembly. On the one hand, this can provide a more closed environment for the separation bin 1 to reduce the power of the air pressure fan mechanism, and on the other hand, the cover plate assembly can be used to achieve intermittent discharge of fruit stems to facilitate replacement of fruit stem receiving equipment to avoid fruit stems from falling during replacement of the receiving equipment.

[0025] As a preferred embodiment of the present application, the separation bin 1 is a prismatic structure that is wide at the top and narrow at the bottom. The top outer shell located at the top of the separation bin 1 is an arc structure. The partition plate 4 is an arc plate with the same curvature as the top outer shell. The first airflow channel 5 is composed of the arc plate and the top outer shell and has an arc-shaped structure. The arc-shaped first airflow channel 5 conforms to the principles of fluid mechanics. On the one hand, it can reduce the loss of airflow. On the other hand, it can increase the amount of material entering the feed port 2 of the separation bin 1, thereby improving the separation efficiency and effect of the separation bin 1.

[0026] Preferably, in this embodiment, the docking port 9 on the separation bin 1 that is docked with the cyclone dust removal mechanism 7 is close to the center of the arc plate. The docking port 9 is arranged at this position, which can reduce the power of the negative pressure fan mechanism 8 on the one hand, and ensure that the critical point for separation of the fruit stems is located at a higher position of the separation bin 1 on the other hand, so as to facilitate the separation of the fruit stems from the airflow under the action of gravity, and also facilitate the storage of the fruit stems of the separation structure near the bottom of the separation bin 1.

[0027] The separation device of this embodiment can be docked with various other devices storing separated mixtures. This embodiment takes the separation device and the negative pressure bellows 14 as an example to illustrate its specific use principle: See also Figure 3 , which is a structural schematic diagram of the dried fruit dust and stalk suction separation device provided by an embodiment of the present invention, which is used in conjunction with a negative pressure bellows 14 through a connecting pipe 15 (the cyclone dust removal mechanism 7 and the negative pressure fan mechanism 8 are omitted in the view, and the arrows in the figure indicate the direction of air flow). When in use, a mixture of dried fruit, stalks and dust is continuously fed into the air pressure bellows through a vibrating conveying screen. Through the separation device of the present application, the mixture of stalks and dust can be sucked into the separation bin 1 through the feed port 2 of the separation bin 1, and the mixture is sucked into the separation bin 1 under the action of the negative pressure airflow. Flowing along the cyclonic airflow path, during operation, when the mixture flows with the airflow to the intersection of the inlet end of the second airflow channel 6 and the outlet end of the first airflow channel 5, the fruit stems will fall to the discharge port 3 under the action of gravity and centrifugal force because their specific gravity is greater than the adsorption force at this position, while the dust will enter the cyclone dust removal mechanism 7 with the airflow due to its lighter specific gravity to separate the dust and airflow. The separated dust is discharged through the discharge port of the cyclone dust removal mechanism 7, and the separated clean airflow is discharged through the exhaust port of the cyclone dust removal mechanism 7.

[0028] In summary, the separation equipment of this embodiment is not only simple in structure, easy to operate, and highly practical, but also can efficiently separate fruit stems from dust, meet the existing demand for separation of fruit stems and dust, and has good market prospects. In addition, the fruit stems separated by the separation equipment can be effectively used as feed, etc., which can reduce feed costs and improve economic benefits. Compared with the existing method of directly disposing of fruit stems and dust as debris, it can effectively reduce the waste of resources and the burden on the environment.
