Description

Technical Field

[0001] The present invention relates to the field of plasticizer processing, and in particular to equipment and a process for processing raw materials of bio-based environmentally friendly plasticizers. Background Art

[0002] Castor beans are one of the raw materials for environmentally friendly plasticizers. Usually, castor bean processing requires removing the peel to expose the castor beans, and then crushing the shells on the surface of the castor beans through a crushing mechanism to obtain the castor bean raw materials we need. The Chinese patent application number CN202010189091.3 is a castor plant threshing and shelling device. It uses a washing and threshing mechanism and a double-channel separation and shelling mechanism to achieve cleaning and threshing of the entire castor plant. It can also use double-barrel cleaning with automatic water inlet and drainage, and perform efficient shelling after separation, reducing manual labor. The invention relates to a device for shelling castor beans, which can reduce the workload, and at the same time will not waste the stems or affect the incision of the stems, and realize the rapid separation of the stems and castor beans. At the same time, the incision of the stems is clean after trimming, thereby reducing the dust generation in the castor seed production process. However, in the process of shelling castor beans, due to the smooth surface of the castor beans, the crushing mechanism has difficulty in shelling the castor beans, resulting in the castor beans cannot be effectively shelled, and the crushed shells cannot be completely separated from the castor beans, resulting in the need for manual secondary sorting after the castor seeds are shelled, and then the shells must be removed before they can be collected, which greatly reduces the production efficiency.

[0003] At the same time, in the process of crushing the shells of castor seeds, the castor seeds are easily broken, making it difficult for the device to produce complete castor seeds. The broken castor seeds affect the later collection and processing, resulting in a significant reduction in the later use effect of the castor seeds. Summary of the Invention

DETAILED DESCRIPTION

[0039] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] Example 1

[0041] like Figure 4-Figure 8 As shown, a bio-based environmentally friendly plasticizer raw material processing equipment includes a first support frame 1, a second support frame 2, a feed bin 3, a blower 4, a sieve plate 5 and a discharge bin 6; the second support frame 2 is installed on the front side of the first support frame 1; the feed bin 3 is provided on the second support frame 2; the blower 4 is installed on the lower side of the second support frame 2, and the blower 4 is located below the feed bin 3; the sieve plate 5 is provided on the front side of the second support frame 2, and the right side of the sieve plate 5 is inclined upward from front to back when viewed from right to left; a collecting hole 5001 is opened on the sieve plate 5; and the discharge bin 6 is connected to the lower side of the sieve plate 5;

[0042] The crushing assembly is connected to the inner side of the feed bin 3; a plurality of separation blocks 7 are connected to the crushing assembly; a plurality of triangular rods 8 are arranged on the crushing assembly; a shaking assembly is installed on the rear side of the second support frame 2; a separation system is arranged on the lower side of the screen plate 5; after the castor raw material with castor shell is manually put into the feed bin 3, the peel on the surface of the castor is peeled off by the crushing assembly, and when the peeled castor seeds fall into the inner wall of the crushing assembly, the shells on the castor seeds are separated by the separation blocks 7, while preventing the crushing assembly from damaging the castor seeds and ensuring the integrity of the castor seeds. In the process of shelling the castor seeds, the separation blocks 7 and the triangular rods 8 cooperate to make the castor seeds stuck between the adjacent triangular rods 8, and the separation blocks 7 are used to peel off the shells of the castor seeds stuck on the triangular rods 8. At the same time, the slightly rotating triangular rod 8 produces a slight rotation when the castor seeds are shelled by the separation block 7, which facilitates the shelling of the separation block 7 and prevents the castor seeds from being unable to rotate and being broken by the separation block 7, resulting in a decrease in the production quality of the castor seeds. At this time, the shelled castor seeds fall onto the sieve plate 5 through the lower side of the feed bin 3, and fall into the discharge bin 6 through the collection hole 5001 on the sieve plate 5. At the same time, the peeled peel and shell fall into the discharge bin 6 through the collection hole 5001. In order to prevent them from mixing into the discharge bin 6, the collection hole 5001 is blown by the blower 4. Since the peel and shell are relatively light, the peel and shell cannot enter the discharge bin 6 through the collection hole 5001, thereby separating the castor seeds from impurities such as peel and shell. While ensuring that the castor seeds are shelled intact, impurities such as peel and shell are removed, thereby improving the production quality of the equipment.

[0043] The separation blocks 7 are arranged relatively to each other in different lengths. During the rotation of the separation blocks 7 of different lengths, the longer end of the separation block 7 shells the castor seeds, and the shorter end of the separation block 7 limits the rotation of the castor seeds during shelling, preventing the castor seeds from rotating, which would cause the separation block 7 to be unable to shell the castor seeds, thereby ensuring that the separation block 7 shells the castor seeds normally, thereby improving the shelling effect of the equipment.

[0044] The crushing assembly includes a rotating drum 105, a first elastic member 106, a first connecting rod 107, a snap ring 108, a second elastic member 109 and a limiting rod 110; the rotating drum 105 is rotatably connected to the middle part of the inner side of the feeding bin 3; a plurality of first elastic members 106 are arranged in a ring on the outer surface of the rotating drum 105, and the first elastic member 106 is a spring; each first elastic member 106 is fixedly connected to a first connecting rod 107, and each first connecting rod 107 is fixedly connected to the adjacent separation block 7; a snap ring 108 is fixedly connected to the left and right sides of the feeding bin 3; a plurality of second elastic members 109 are arranged in a ring on the two snap rings 108, and the second elastic member 109 is a spring; every two corresponding second elastic members 109 on the left and right are respectively fixed to the adjacent triangular rods 8; a plurality of limiting rods 110 are fixedly connected to the two snap rings 108, and the limiting rods 110 are located in adjacent second elastic members in a group of two. 8, and the first elastic member 106 is slightly contracted by the force applied to the first connecting rod 107, so that the separation block 7 is slightly moved toward the center of the drum 105, thereby avoiding excessive contact between the separation block 7 and the castor seeds, which causes the separation block 7 to crush the castor seeds, thereby ensuring the integrity of the castor seeds.

[0045] The shaking assembly includes an eccentric wheel 102, a push rod 103, a third connecting rod 104 and a second connecting rod 111; the second supporting frame 2 is rotatably connected to the upper rear side of the second connecting rod 111; the eccentric wheel 102 is fixedly connected to the middle of the outer side of the second connecting rod 111; the third connecting rod 104 is fixedly connected to the lower rear side of the sieve plate 5; the push rod 103 is fixedly connected to the middle of the outer side of the third connecting rod 104, and the push rod 103 is always in contact with the outer surface of the eccentric wheel 102; when the shelled castor seeds fall into the sieve plate 5 through the feed bin 3, the eccentric wheel 102 is shaken from right to left. Taking the figure as a reference, the second connecting rod 111 is rotated counterclockwise to drive the eccentric wheel 102 to rotate. After the eccentric wheel 102 rotates, the top rod 103 is pushed to move back and forth through its movement, thereby driving the third connecting rod 104 to move back and forth, causing the sieve plate 5 to shake back and forth, thereby allowing the castor seeds on the sieve plate 5 to be transferred to the discharge bin 6 faster. At the same time, the peel and shell are preliminarily separated from the castor seeds by the shaking of the sieve plate 5, so that the impurity removal effect of the blower 4 is better, further improving the impurity removal effect of the equipment.

[0046] It also includes a DC motor 101; the DC motor 101 is fixedly connected to the upper side of the first support frame 1; the DC motor 101 is driven by the second connecting rod 111 through a pulley, thereby rotating the second connecting rod 111; the DC motor 101 is driven by the pulley and the rotating drum 105; the DC motor 101 is driven by the pulley and the blower 4; the blower 4 is driven to rotate by driving the DC motor 101.

[0047] A bio-based environmentally friendly plasticizer raw material processing equipment and process, including the following working steps:

[0048] S1: Crushing: the first connecting rod 107 rotates and cooperates with the feed bin 3 to crush the castor seed peel;

[0049] S2: Separating the shell: the separation block 7 knocks and crushes the shell on the surface of the castor seeds after rotating, and cooperates with the triangular rod 8 to limit the castor seeds, so that the separation block 7 prevents the castor seeds from rotating during the shell crushing process, thereby ensuring the integrity of the castor seeds after shelling;

[0050] S3: Collecting castor seeds. The rotation trajectory of the eccentric wheel 102 drives the screen plate 5 to vibrate back and forth, and the crushed peel, shell and castor seeds are collected and discharged by the discharge bin 6.

[0051] S4, screening, the air holes 5002 blow air to the lighter peels and shells in the ventilation state to screen the castor seeds and peels and shells, avoiding manual secondary sorting in the later stage;

[0052] S5, interception and guidance, when part of the peel and shell falls into the collecting hole 5001 along with the castor seeds, the blower 4 blows away the lighter peel and shell, and uses the second guide plate 301 to separate the peel and shell from the surface of the sieve plate 5. At the same time, the castor seeds are intercepted by the second guide plate 301, so that the castor seeds pass through the collecting hole 5001 and enter the discharge bin 6.

[0053] Example 2

[0054] On the basis of Example 1, Figures 9-11As shown, the separation system includes an air guide bin 201, a first baffle 202, a second baffle 203 and a partition 204; the lower rear portion of the sieve plate 5 is fixedly connected to the air guide bin 201; the middle inner portion of the air guide bin 201 is fixedly connected to the partition 204, and the air guide bin 201 is separated into two chambers, a first rectangular cavity 20101 and a second rectangular cavity 20102, by the partition 204; a plurality of air holes 5002 are opened in the middle of the right side of the sieve plate 5, and each air hole 5002 is connected to the second rectangular cavity 20102; the air guide bin 201 is fixedly connected to the lower rear portion of the sieve plate 5; the partition 204 is fixedly connected to the middle inner portion of the air guide bin 201, and the air guide bin 201 is separated into two chambers, a first rectangular cavity 20101 and a second rectangular cavity 20102; the middle right portion of the sieve plate 5 is provided with a plurality of air holes 5002, and each air hole 5002 is connected to the second rectangular cavity 20102; 01 is rotatably connected to the first baffle 202 at the lower rear part; the second baffle 203 is rotatably connected to the middle part of the upper side of the partition 204; since the peel and shell fall into the discharge bin 6 together with the castor seeds, it is difficult to screen the castor seeds by only blowing away the peel and shell by the blower 4. At the same time, when the castor seeds fall into the collection hole 5001, the peel and shell are likely to block the collection hole 5001, resulting in the blower 4 being unable to effectively remove the peel and shell. In order to improve the effect of screening castor seeds, when the sieve plate 5 shakes back and forth, the sieve plate 5 drives the guide The wind bin 201 moves forward and backward. When the wind guide bin 201 moves forward, the first baffle 202 is in a closed state, and the first rectangular cavity 20101 and the second rectangular cavity 20102 are in a connected state. When the wind guide bin 201 moves backward, the first baffle 202 opens, and the gas enters the first rectangular cavity 20101. In this reciprocating manner, the gas continuously enters the first rectangular cavity 20101, increasing the air pressure in the first rectangular cavity 20101, thereby pushing open the second baffle 203. At this time, the gas enters the second rectangular cavity 20101. Rectangular cavity 20102, since the gas continuously enters the second rectangular cavity 20102 from the first rectangular cavity 20101, and the second rectangular cavity 20102 is connected with the air hole 5002, the gas forms a high-speed airflow when passing through the air hole 5002 with a smaller aperture, so that the peel and shell passing above the air hole 5002 are blown away. Since castor seeds are heavier than the peel and shell, the castor seeds cannot be blown away by the gas, so that the castor seeds are separated from the peel and shell, further improving the screening effect of the equipment.

[0055] Based on reading from right to left, Figure 10 As shown, the air holes 5002 are arranged to be inclined from the lower left to the upper right; the peel and shell are guided to the rear side by the inclined air holes 5002, and the castor seeds move to the front side, so that the peel and shell are better separated from the castor seeds, and the castor seed screening of the equipment is further improved.

[0056] like Figure 11As shown, it also includes a first guide plate 205; a plurality of first guide plates 205 are fixedly connected to the rear side of the sieve plate 5, and each air hole 5002 is located between two adjacent first guide plates 205; based on the direction from front to back, the first guide plate 205 located on the left is tilted to the left, and the first guide plate 205 located on the right is tilted to the right; when the air holes 5002 are in the process of blowing away the peel and shell, in order to prevent the peel and shell from blocking the castor seeds from falling into the discharge bin 6, the peel and shell in the blowing process are guided to the left and right by the first guide plates 205 extending to the left and right sides, thereby avoiding the castor seeds being blocked by the peel and shell, and ensuring the normal screening of the castor seeds by the equipment.

[0057] Example 3

[0058] On the basis of Examples 1 and 2, Figure 1-Figure 3 、 Figure 12 and Figure 13 As shown, a second guide plate 301 is also included; the second guide plate 301 is fixedly connected to the upper front side of the sieve plate 5, and the second guide plate 301 is located in front of the air hole 5002; since the air hole 5002 cannot hold the castor seeds in the process of falling, the castor seeds easily pass through the air hole 5002 and accumulate on the sieve plate 5, affecting the collection of the castor seeds by the equipment. In order to prevent this phenomenon, when the castor seeds fall into the air hole 5002, the castor seeds are intercepted by the second guide plate 301, so that the castor seeds fall into the air hole 5002, thereby preventing the castor seeds from accumulating on the sieve plate 5 and ensuring the collection of the castor seeds by the equipment.

[0059] Taking the view from right to left as the reference, the second guide plate 301 is tilted from the lower right to the upper left. While the castor seeds are intercepted by the tilted second guide plate 301, a small amount of peel and shell that fall on the air hole 5002 is discharged from the sieve plate 5 through the blower 4 in cooperation with the second guide plate 301, preventing the peel and shell from accumulating on the sieve plate 5 and falling into the discharge bin 6, thereby improving the cleaning effect of the equipment on the peel and shell.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
