Description

Technical Field

[0001] The invention relates to the field of environmentally friendly impurity removal and separation equipment, and specifically to a raw material impurity removal and separation device and a process thereof. Background Art

[0002] Preserved fruit, also known as candied fruit, is a product made from fruits and vegetables as the main raw materials, pickled with sugar or honey. Before processing the preserved fruit, the picked raw materials are mixed with a lot of impurities, such as hair, branches and leaves, braided ropes, straw ropes and other light impurities, as well as plastic sheets, gravel, metal sheets and other high-density impurities, so the impurities in the raw materials need to be screened out before the next step of processing can be carried out.

[0003] The prior art discloses a Chinese patent with publication number CN 203292091 U: a candied fruit conveying and impurity removal device, and discloses a material discharge rack, on which evenly distributed impurity removal holes are provided. After the fruit is conveyed to a certain height, the fruit is rolled down by gravity, and the impurities are separated from the fruit during the rolling and sliding process, so that the impurities are filtered out from the impurity removal holes.

[0004] However, the above-mentioned prior art still has certain defects, that is, during use, the impurities stuck on the surface of the fruit are easily unable to be separated from the fruit due to the way that the fruit rolls and slides down by itself to remove impurities. At the same time, the impurities stuck on the surface of the unloading rack are also easy to stick to the surface of other fruits again and slide down along with the fruit, thereby resulting in incomplete impurity removal.

DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] The raw material impurity removal and separation device of the present invention belongs to one of the advanced environmental protection industries. The impurities mixed in the candied fruit raw materials belong to a part of solid waste pollution. In the actual production process, they need to be classified and impurity removed.

[0055] Example 1

[0056] Refer to the instruction manual Figure 1-2 and Figure 6 A raw material impurity removal and separation device according to an embodiment of the present invention comprises a material hoist 2, a screening device 1, and a vibrating screen and singeing mechanism 6, wherein the screening device 1 is fixedly installed between the discharge end of the material hoist 2 and the feed end of the vibrating screen and singeing mechanism 6;

[0057] The vibrating screening and singeing mechanism 6 includes a vibrating screening assembly 66 for separating residual impurities in the candied fruit raw materials, a singeing assembly 67 for burning light-density suspended impurities entangled on the surface of the candied fruit raw materials, an ash cleaning assembly 68 for removing residual ash remaining on the surface of the candied fruit raw materials, a confluence assembly 65 for centrally collecting high-density impurities in the candied fruit raw materials, and a bearing portion for carrying the vibrating screening assembly 66, the singeing assembly 67, the ash cleaning assembly 68 and the confluence assembly 65.

[0058] It should be noted that the present invention utilizes a material hoist 2 to disperse the material to be removed (here, the candied fruit raw material) and then transports it to the inside of a screening device 1 for screening, thereby classifying and separating light-density suspended impurities (such as hair, branches and leaves, braided ropes, straw ropes, etc., the same below) and high-density impurities (such as plastic sheets, gravel, metal sheets, etc., the same below) mixed in the material, and further separates the residual light-density suspended impurities and high-density impurities mixed in the material through a vibrating screen singeing mechanism 6, thereby improving the removal effect.

[0059] Specifically, Figure 1 and Figure 3-5 As shown, the screening device 1 comprises a screening drum and a material guide cover 12 fixed at the bottom of the screening drum, a plurality of leak holes 11 are provided on the surface of the screening drum corresponding to the position of the material guide cover 12, and the outer sides of both ends of the screening drum are respectively connected with a feed hopper and a discharge pipe, and the inner sides of both ends of the screening drum are respectively fixed with a left end frame 13 and a right end frame 14;

[0060] A rotating shaft 9 is rotatably installed between the left end frame 13 and the right end frame 14, and a plurality of knocking rods 10 are arranged outside the rotating shaft 9. A blower 3 and an exhaust fan 4 are respectively fixedly installed at both ends of the screening cylinder, wherein the blower 3 adopts a centrifugal fan of model cf-11, and the exhaust fan 4 adopts a fan of model PY160H. A transition cylinder 5 is fixedly installed between the screening cylinder and the air outlet end of the blower 3, and a driving motor for driving the rotating shaft 9 to rotate is arranged inside the transition cylinder 5. The transition cylinder 5 is used to connect the blower 3 and the exhaust fan 4. The air outlet end of the blower 3 forms an air duct with the screening cylinder and is also used as a mounting seat for the drive motor. A support rod 15 is fixedly connected between the outer side of the drive motor and the inner side of the transition cylinder 5. Three support rods 15 are evenly distributed along the outer circumference of the drive motor to fix the drive motor inside the transition cylinder 5 and form an air passage between the drive motor and the inner circumference of the transition cylinder 5, so that the wind blown by the blower 3 can separate the light-density suspended impurities from the material and take away the heat generated by the drive motor at work.

[0061] Furthermore, each group of knocking rods 10 is provided with a plurality of them, and the plurality of knocking rods 10 of each group are distributed in a spiral shape along the outer peripheral surface of the rotating shaft 9, which can not only knock out the impurities of the material, but also guide the material to be transported in the direction of the discharge pipe;

[0062] The right end frame 14 includes an outer ring 141 and an inner ring 142 which are concentrically arranged, and a cylinder 143 is rotatably installed between the outer ring 141 and the inner ring 142 through a bearing, and an impeller 144 is fixedly sleeved on the middle part of the outer side of the cylinder 143, wherein the rotatable installation of the cylinder 143 enables the airflow to drive the cylinder 143 to rotate after blowing onto the impeller 144, so that after the light-density suspended impurities are hung on the cylinder 143, they can gradually separate from the cylinder 143 as the cylinder 143 rotates, thereby effectively preventing the light-density suspended impurities from being entangled on the cylinder 143.

[0063] It should be noted that when the light-density suspended impurities and high-density impurities mixed in the material entering the screening cylinder are separated in the first stage, the driving motor drives the rotating shaft 9 to rotate, thereby driving the knocking rod 10 to knock the material to separate the impurities mixed in the material. Specifically, the high-density impurities in the material sink and pass through the leakage hole 11 into the material guide cover 12 to be discharged, while the light-density suspended impurities are lifted up and drawn out of the screening cylinder by the blowing and suction of the blower 3 and the exhaust fan 4. In addition, in the process of using the rotating knocking rod 10 to knock the material to separate the impurities, the knocking rod 10 with a spiral structure can also be used to guide and transport the material in the screening process.

[0064] Specifically, Figure 6-8 As shown, the bearing part includes a bracket 61, a bearing platform 62 is fixedly provided on the top of the bracket 61, an impurity groove and a raw material groove are opened on the top surface of the bearing platform 62, and one end of the raw material groove on the bearing platform 62 is fixedly connected to a discharge tray 64, wherein the bottom end surface of the inner cavity of the raw material groove and the bottom end surface of the inner cavity of the discharge tray 64 are both provided with inclined structures to guide the impurity-removed materials to move to the discharge port at the location, and two partitions 63 are fixedly provided inside the impurity groove, wherein the two partitions 63 can be used to divide the interior of the impurity groove into an impurity collection area and two vacant areas, so that the installation of the vibration screen component 66 and the impurity collection of the confluence component 65 do not interfere with each other, a through groove is opened through the bottom of the raw material groove, the vibration screen component 66 is mounted between the opposite sides of the two partitions 63, the singeing component 67 is arranged at the position corresponding to the through groove on the bracket 61, the cleaning component 68 is arranged on the top of the discharge tray 64, and the confluence component 65 is arranged on the outer side of the bearing platform 62 corresponding to the position between the opposite sides of the two partitions 63.

[0065] It should be noted that the present invention reasonably distributes the vibrating screen assembly 66, the singeing assembly 67, the cleaning assembly 68 and the confluence assembly 65 on the support platform 62, so that the four processes of secondary separation of impurities still remaining in the material after the primary separation, burning and removing impurities entangled on the surface of the material, cleaning the residual ash remaining on the surface of the material after burning and removing impurities, and classifying and collecting the residual light-density suspended impurities and high-density impurities separated from the secondary separation do not interfere with each other, but work together to complete the cleaning and sufficient separation of the residual impurities in the material after the primary separation.

[0066] Specifically, Figure 8-9 As shown, the vibrating screen assembly 66 includes a sieve plate 661 disposed on the top of the carrier platform 62, a material guide cover 662 is fixedly connected to the bottom of the sieve plate 661, and a perforated plate is fixedly provided at the joint between the sieve plate 661 and the material guide cover 662, a straight spring 664 and a telescopic sleeve rod 663 are fixedly connected between the bottom of the sieve plate 661 and the bottom end surface of the inner cavity of the impurity tank, and a vibration motor is fixedly installed on the outside of the sieve plate 661, wherein the telescopic sleeve rod 663 is composed of a sleeve column fixed on the sieve plate 661 and a sleeve fixed in the impurity tank, and one end of the sleeve column is always movably plugged into the sleeve;

[0067] A rotating rod 665 driven by a motor is rotatably installed inside the raw material outlet end of the sieve plate 661, and multiple groups of hook plates 666 are fixedly installed on the outer side of the rotating rod 665. An inclined plate 667 is also fixedly installed inside the raw material outlet end of the sieve plate 661, and a tooth opening 668 is opened at one end of the inclined plate 667 corresponding to the position of each group of hook plates 666, wherein each group of hook plates 666 corresponds to the tooth opening 668 on the inclined plate 667, so that it will not affect the rotation of the hook plate 666, and the inclined plate 667 can be used to guide and collect the light-density suspended impurities that separate from the hook plate 666 during the rotation. In addition, the width between two adjacent groups of hook plates 666 is greater than the maximum length of the material, so that in the process of separating the light-density suspended impurities from the sieve plate 661, the material can fall back to the sieve plate 661 through the gap between the two adjacent groups of hook plates 666, thereby preventing the material from being discharged onto the inclined plate 667 together with the light-density suspended impurities.

[0068] It should be noted that when the impurities remaining in the material after the primary separation and impurity removal are subjected to secondary separation, the sieve plate 661 is vibrated by the exciting force generated by the vibration motor installed on the outside of the sieve plate 661 during operation, and during the vibration process, the vibration direction of the sieve plate 661 is limited by the telescopic sleeve 663, so that the sieve plate 661 can only move in the vertical direction under the restriction of the straight spring 664, so that the material falling into the sieve plate 661 through the discharge pipe jumps, and the high-density impurities remaining in the material are removed. The impurities will sink and pass through the perforated plate into the guide cover 662 for discharge, while the light-density suspended impurities remaining in the material will float up and when they move with the material to the discharge port of the sieve plate 661, the rotating hook plate 666 will continuously move the material to extend the time the material stays in the sieve plate 661. At the same time, in the process of moving the material, the rotating hook plate 666 will pick up the light-density suspended impurities on the upper layer of the sieve plate 661, and after moving to a certain height with the hook plate 666, the impurities will slide along the hook plate 666 to the top of the inclined plate for collection.

[0069] Specifically, Figure 6-8 and Figure 10-11 As shown, the singeing assembly 67 includes an electric push rod 671 fixedly mounted on the top of the bracket 61, and the telescopic end of the electric push rod 671 is fixedly connected to a trapezoidal lifting platform 672, and guide blocks 674 are fixedly provided at the top middle of both sides of the trapezoidal lifting platform 672, and guide grooves 673 are provided at the positions corresponding to the guide blocks 674 at the bottom of both sides of the carrier 62, and the guide blocks 674 are slidably connected to the inside of the guide grooves 673 at the corresponding positions, wherein, when the electric push rod 671 is in an unextended state, the top of the guide block 674 is still maintained in the inside of the guide groove 673, so that the trapezoidal lifting platform 672 can perform stable vertical lifting movement along the guide groove 673;

[0070] A transverse axis groove is provided through the top of the trapezoidal lifting platform 672, and a roller 675 driven by a motor is rotatably installed between the opposite sides of the two guide blocks 674, wherein the roller 675 is partially exposed to the outside of the transverse axis groove, and anti-skid protrusions are added on the surface of the roller 675 to better drive the material to rotate. A U-shaped frame 676 is fixedly provided at the bottom of the trapezoidal lifting platform 672, and a flame head 677 is installed on the inner side of the U-shaped frame 676, wherein the flame sprayed by the flame head 677 can be used for light-density suspended impurities wrapped around the surface of the material, and cooperate with the roller 675 to drive the material to rotate, so as to achieve comprehensive burning and impurity removal of light-density suspended impurities wrapped around the surface of the material, and a baffle 678 is fixedly provided at the position corresponding to the through groove on the top of the inner side of the raw material trough, and a material passing trough is formed between the bottom end of the baffle 678 and the bottom end surface of the inner cavity of the raw material trough, wherein the material passing trough can only allow the material to pass through to be placed in a single layer on the inclined side of the trapezoidal lifting platform 672.

[0071] It should be noted that in the process of burning and removing light-density suspended impurities wrapped around the surface of the material, whenever the trapezoidal lifting platform 672 moves to the lowest point along with the electric push rod 671, the material falling into the raw material trough will pass through the material passing channel formed between the bottom end of the baffle 678 and the bottom end surface of the inner cavity of the raw material trough and fall to the top of the inclined surface on the trapezoidal lifting platform 672. At this time, the flame head 677 will spray flames to burn the impurities wrapped around the surface of the material. At the same time, the rotating roller 675 driven by the motor will drive the material to rotate, so that all sides of the material can contact the flame, thereby achieving comprehensive burning and impurity removal and improving the effect of burning and impurity removal.

[0072] Specifically, Figure 8 and Fig.12 As shown, the dust cleaning component 68 includes a U-shaped frame 681 fixed on the top of the unloading tray 64, and a roller brush 682 driven by a motor is rotatably installed on the inner side of the U-shaped frame 681, wherein the distance between the end of the bristles on the outer side of the roller brush 682 and the bottom end surface of the inner cavity of the unloading tray 64 is less than the radial length of the material, and the rotating roller brush 682 can be used to clean the material passing through the inner area of ​​the U-shaped frame 681 to remove the residual ash remaining on the surface of the material during the aforementioned burning and impurity removal process. An air outlet channel 683 and an air exhaust channel 684 are fixedly installed at both ends of the U-shaped frame 681, respectively. The air outlet channel 683 is connected to the top of the air exhaust channel 684 and is respectively connected to an air supply pipe 686 and an air exhaust pipe 685, wherein the air outlet channel 683 is inclined relative to the inner top end surface of the U-shaped frame 681 (see for details). Fig.12 ) can make the blown air flow blow obliquely upward, so that the remaining ash brushed off by the roller brush 682 is blown toward the direction of the exhaust channel 684.

[0073] It should be noted that when cleaning the residual ash remaining on the surface of the material after burning and removing impurities, as the trapezoidal lifting platform 672 pushes the material upward, the inner wall of the raw material trough will gradually release the stop on the material. After the material is completely free from the obstruction of the raw material trough, the material will roll along the inclined surface of the trapezoidal lifting platform 672 to the discharge tray 64, and move along the discharge tray 64 to the discharge port of the lower tray 64. In this process, the rotating roller brush 682 is used to clean the residual ash remaining on the surface of the material. At the same time, the circulating airflow between the air outlet duct 683 and the exhaust duct 684 is used to blow away the brushed residual ash for collection, so as to prevent the residual ash from escaping into the working environment.

[0074] Specifically, Figure 1 and Figure 8 As shown, the confluence assembly 65 includes a notch 651 opened on one side of the carrier 62 and connected to the impurity groove, and an inclined material guide frame 652 is fixedly connected to the outer side of the carrier 62 at a position corresponding to the notch 651 .

[0075] It should be noted that the high end of the material guide frame 652 extends to the discharge end of the material guide cover 12, which can guide the high-density impurities separated in the primary separation process to the impurity groove on the support platform 62, and gather them with the high-density impurities separated in the secondary separation process in the impurity groove, which is convenient for subsequent centralized cleaning.

[0076] Example 2

[0077] Refer to the instruction manual Figure 1-2 and Figure 13-14 , a raw material impurity removal and separation device according to an embodiment of the present invention, the light impurity discharge end of the screening device 1 is connected with a light impurity processing mechanism 8 for briquetting the collected light-density suspended impurities, the light impurity processing mechanism 8 comprises a filter box 81 fixedly installed at the air outlet position of the exhaust fan 4, the filter box 81 is fixedly provided with filter plates 82 at the top and bottom of the air outlet position of the exhaust fan 4, the filter box 81 is hingedly provided with a box door on one side away from the exhaust fan 4, and the two filter plates 82 are provided with a pressing mechanism at one end close to the box door;

[0078] The two pressing mechanisms include through slots formed on the filter plates 82, and deflection arc blocks 83 are installed at the ends of the two through slots near the box door. Deflection plates 84 are hingedly installed on the opposite sides of the two filter plates 82, and reset components 85 are arranged between the opposite sides of the two deflection plates 84 and the corresponding filter plates 82. The reset components 85 can make the two deflection plates 84 present as follows when there is no external force. Fig.13 The state shown ensures that the light impurity processing space is maximized. The positions of the two deflection arc blocks 83 on the inner side of the filter box 81 are fixedly installed with electric push rods 86. The telescopic ends of the two electric push rods 86 are fixedly connected with push strips 87, wherein the side of the push strip 87 facing the deflection arc block 83 is set as an arc, and the edge of one end of the push strip 87 facing the filter plate 82 at the position is moved in contact with the filter plate 82, which can ensure that when the deflection arc block 83 is pushed to the maximum position, the two deflection plates 84 are passively deflected to be able to isolate the cavity between the opposite sides of the two filter plates 82;

[0079] The reset assembly 85 includes an arc rod 851 fixedly connected to the deflection plate 84 and an arc tube 852 fixedly connected to the filter plate 82, and one end of the arc rod 851 is movably inserted into the arc tube 852, and an arc spring 853 is fixedly connected between one end of the arc rod 851 located inside the arc tube 852 and the inner cavity end surface of the arc tube 852. Fig.13 In the state shown, the arc spring 853 is still in a compressed state, so that the corresponding deflection arc block 83 is lifted up by utilizing the compression restoring force of the arc spring 853.

[0080] It should be noted that when the light-density suspended impurities collected in the filter box 81 are processed, the push rod 87 is pushed to the right by the electric push rod 86 (refer to Fig.13 ), the moving push bar 87 will push the deflection arc block 83 to deflect, and the deflected deflection arc block 83 will push the deflection plate 84 to deflect accordingly, specifically: the two deflection arc blocks 83 and the two deflection plates 84 are deflected towards each other, during this process, the ends of the two deflected deflection plates 84 that are close to each other will gradually close, and the cavity between the opposite sides of the two filter plates 82 will be separated, and the two deflected deflection arc blocks 83 will compress the light-density suspended impurities collected inside the filter box 81, which can facilitate the subsequent cleaning of the collected light-density suspended impurities on the one hand, and make full use of the collection space inside the filter box 81 on the other hand;

[0081] In addition, when it is necessary to take out the light-density suspended impurities after briquetting from the filter box 81, the deflection arc block 83 can be kept pushed to the maximum limit, and two closed deflection plates 84 can be used to separate the collection cavity. At this time, the box door can be opened to take out the impurities compressed into blocks. In this way, it can be ensured that the cleaning of block materials and the uninterrupted collection of light-density suspended impurities are carried out simultaneously.

[0084] It should be noted that each time the servo motor drives the indexing column 73 to rotate a unit angle, the corresponding vacant bagging ring 74 can move to the material discharge port of the discharge tray 64. When the impurity-free material is bagged, the packaging bag is pre-set on the bottom end of the bagging ring 74 and fixed, and then driven by the driving motor to perform rotary continuous position switching, so as to realize continuous and uninterrupted packaging of the impurity-free material into bags.

[0085] Furthermore, in the process of packaging the removed materials into bags, a robotic arm can be used to bag and fix the materials according to actual production needs to improve production efficiency.
