Description

A sieve for separating impurities from scallion skin Technical Field

[0001] This utility model relates to the field of scallion processing technology, specifically to a scallion skin impurity separation sieve. Background Technology

[0002] Shallots have a slightly spicy and sweet flavor and are rich in nutrients such as sugar, protein, and vitamins, making them a popular fruit and vegetable. Before processing, shallots need to be soaked to remove impurities and damaged skin from their surface. While existing separating screens can effectively separate impurities such as damaged skin floating on the water surface, they are not effective at separating impurities such as damaged skin that have not completely detached from the shallot surface. Furthermore, thin and light skin impurities are not easily collected quickly.

[0003] In view of this, we have studied and improved the existing structure and its shortcomings, and proposed a scallion skin impurity separation sieve. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a scallion skin impurity separation sieve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scallion skin impurity separation sieve, comprising a sieve box, a centrifugal sieve frame, and a separation and collection assembly. The centrifugal sieve frame is installed inside the sieve box, and a feed pipe is fixed on the upper side of the centrifugal sieve frame. A drive assembly is installed on the outer side of the feed pipe. The separation and collection assembly is installed on the lower right side of the sieve box, and the separation and collection assembly includes a collection box, a material collection drawer, an air outlet filter, a baffle, and a pull-out groove. The material collection drawer is slidably installed on the lower inside of the collection box, and an air outlet filter is fixed on the upper side of the collection box. The air outlet filter has an inclined structure. A baffle is slidably installed on the left side of the collection box, and a pull-out groove corresponding to the baffle is opened on the outer wall of the sieve box. Three fans are equidistantly installed on the lower left side inside the sieve box.

[0006] Furthermore, a guide plate is fixed inside the centrifugal sieve frame by a connecting rod, and the guide plate has a conical structure, with the vertical center line of the guide plate coinciding with the vertical center line of the centrifugal sieve frame.

[0007] Furthermore, the drive assembly includes a driven gear and a driving gear. The driven gear is fixed to the outside of the feed pipe and meshes with the driving gear. The drive assembly also includes a rotating shaft and a drive motor. The rotating shaft is fixed to the middle of the driving gear, and the drive motor is mounted on the upper side of the rotating shaft. The drive motor is fixedly connected to the upper wall of the screen box.

[0008] Furthermore, a support rod is fixed to the upper side of the screen box, and a feed hopper is installed above the support rod, with the lower side of the feed hopper rotatably connected to the feed pipe.

[0009] Furthermore, the centrifugal sieve frame has a cylindrical structure, and the outer and lower side walls of the centrifugal sieve frame are both perforated mesh structures, and a discharge pipe is fixed in the middle of the bottom of the centrifugal sieve frame.

[0010] Furthermore, the lower side of the discharge pipe penetrates the lower plate of the screen box, and both the discharge pipe and the feed pipe are rotatably connected to the screen box.

[0011] Furthermore, a partition is fixed inside the sieve box, and the partition is rotatably connected to the centrifugal sieve frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up a centrifugal sieve frame, the drive component facilitates the rotation of the centrifugal sieve frame to generate centrifugal force, which facilitates the screening of surface impurities in the scallions inside the centrifugal sieve frame. Under the action of centrifugal force, the scallions are thrown towards the edge of the centrifugal sieve frame. Because the surface impurities are thin and light, they are more likely to fall through the gaps in the centrifugal sieve frame, while the scallions remain inside the centrifugal sieve frame, thereby achieving the separation of surface impurities from scallions. The setting of the feed hopper facilitates the feeding of scallions in conjunction with the feed pipe, and the setting of the conical structure of the guide plate facilitates the uniform dropping of scallions, making the scallions evenly distributed.

[0014] 2. By setting up a separate collection component, the sliding baffle can be easily removed to connect the screen box and the collection box. Three fans can blow thin and light surface impurities inside the screen box, allowing the impurities to enter the collection box. At this time, the air outlet filter can not only facilitate air outlet but also intercept impurities, so that the impurities are concentrated and fall into the inside of the collection drawer under the action of gravity, realizing the collection of impurities. The collection drawer can be easily removed and cleaned by pulling it out. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of protection of this utility model.

[0020] As shown in Figure 1, a scallion skin impurity separation sieve of this embodiment includes a sieve box 1, a centrifugal sieve frame 2, and a separation and collection assembly 7. The centrifugal sieve frame 2 is installed inside the sieve box 1. A feed pipe 5 is fixed to the upper side of the centrifugal sieve frame 2, and a drive assembly 6 is installed on the outer side of the feed pipe 5. The drive assembly 6 includes a driven gear 601 and a driven gear 602. The driven gear 601 is fixed to the outer side of the feed pipe 5 and meshes with the driven gear 602. The drive assembly 6 also includes a rotating shaft 603 and a drive motor 604. The rotating shaft 603 is fixed to the middle of the drive gear 602, and the drive motor 604 is installed on the upper side of the rotating shaft 603. The drive motor 604 is fixedly connected to the upper wall of the sieve box 1. A partition 12 is fixed inside the sieve box 1, and the partition 12 is rotatably connected to the centrifugal sieve frame 2.

[0021] Specifically, the drive motor 604 and the rotating shaft 603 drive the active gear 602 to rotate. The active gear 602 meshes with the passive gear 601, which in turn drives the passive gear 601 to rotate. This causes the passive gear 601, the feed pipe 5, and the centrifugal screen frame 2 to rotate, so as to screen the scallions inside the centrifugal screen frame 2 for surface impurities. The broken scallions have thin and light skins, and under the action of centrifugal force, they are thrown to the edge of the screen. Finally, under the combined action of centrifugal force and gravity, they fall out of the holes of the centrifugal screen frame 2, while the scallions remain inside the centrifugal screen frame 2, thereby achieving the separation of surface impurities from the scallions.

[0022] As shown in Figures 1-3, a separation and collection assembly 7 is installed on the lower right side of the screen box 1. The separation and collection assembly 7 includes a collection box 701, a material drawer 702, an air filter 703, a baffle 704, and a pull-out groove 705. The material drawer 702 is slidably installed on the lower side of the inside of the collection box 701, and the air filter 703 is fixed on the upper side of the collection box 701. The air filter 703 has an inclined structure. The baffle 704 is slidably installed on the left side of the collection box 701. At the same time, a pull-out groove 705 corresponding to the baffle 704 is opened on the outer wall of the screen box 1. Three fans 8 are installed at equal intervals on the lower left side of the inside of the screen box 1.

[0023] Specifically, by installing a sliding pull-out baffle 704, the screen box 1 can be easily moved and pulled out to connect with the collection box 701. The three fans 8 can blow the thin and light damaged surface impurities inside the screen box 1 into the collection box 701 on one side. At this time, the inclined air outlet filter 703 can facilitate air outlet on the one hand, and intercept the blown impurities on the other hand, so that the impurities are concentrated and fall into the collection drawer 702 under the action of gravity, thus collecting the impurities. The collection drawer 702 can be easily removed for cleaning by pulling it out.

[0024] As shown in Figures 1 and 3, a guide plate 4 is fixed inside the centrifugal sieve frame 2 by a connecting rod 3. The guide plate 4 has a conical structure, and its vertical center line coincides with the vertical center line of the centrifugal sieve frame 2. A support rod 9 is fixed on the upper side of the sieve box 1, and a feed hopper 10 is installed above the support rod 9. The lower side of the feed hopper 10 is rotatably connected to the feed pipe 5. The centrifugal sieve frame 2 has a cylindrical structure, and the outer and lower side walls of the centrifugal sieve frame 2 are hollow mesh structures. A discharge pipe 11 is fixed in the middle of the bottom of the centrifugal sieve frame 2. The lower side of the discharge pipe 11 penetrates the lower plate of the sieve box 1, and both the discharge pipe 11 and the feed pipe 5 are rotatably connected to the sieve box 1.

[0025] Specifically, the support rod 9 is used to support the feed hopper 10. The feed hopper 10 is designed to facilitate the feeding of scallions with the feed pipe 5. The connecting rod 3 is used to fix the guide plate 4. The conical structure of the guide plate 4 facilitates the even distribution of scallions. The discharge pipe 11 and the feed pipe 5 are rotatably connected to the screen box 1, which does not affect the rotation of the centrifugal screen frame 2. A corresponding butterfly valve can also be installed at the discharge pipe 11 to control the discharge of scallions inside the centrifugal screen frame 2.

[0026] Working Principle: First, the scallions are fed through the feed hopper 10 and feed pipe 5. The conical guide plate 4 facilitates even distribution of the scallions. Then, the drive motor 604 and rotating shaft 603 drive the drive gear 602 to rotate, which in turn drives the driven gear 601. This rotation of the driven gear 601, feed pipe 5, and centrifugal screen frame 2 generates centrifugal force, which separates the surface impurities of the scallions inside the centrifugal screen frame 2. Under centrifugal force, the scallions are thrown towards the edge of the centrifugal screen frame 2. The thin and light surface impurities are more easily dislodged through the pores of the centrifugal screen frame 2, while the scallions remain inside the centrifugal screen frame 2. The separation of surface impurities from scallions is achieved through a butterfly valve installed at the discharge pipe 11 to control the discharge of scallions from the centrifugal sieve frame 2. After the surface impurities are separated, the baffle 704 is slidably pulled out, connecting the sieve box 1 to the collection box 701. Three fans 8 then blow the surface impurities inside the sieve box 1, causing them to enter the collection box 701. The air filter 703 intercepts the impurities while discharging air, ultimately causing the impurities to fall into the collection drawer 702 under gravity, thus achieving impurity collection. The collection drawer 702 can also be pulled out for cleaning, completing the usage process of the scallion surface impurity separation sieve.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
