Description

Technical Field

[0001] The invention belongs to the technical field of white silkworm impurity removal, and in particular relates to a white silkworm impurity removal device and an impurity removal method. Background Art

[0002] As a commonly used traditional Chinese medicine, the quality of Bombyx batryticatus directly impacts the efficacy and safety of medicinal products. After collection, Bombyx batryticatus is often contaminated with various impurities, such as silkworm feces, dust, mulberry leaves, mulberry stems, cocoon debris, stones, and other foreign matter. These impurities not only reduce the purity of the Bombyx batryticatus but may also introduce harmful microorganisms or other contaminants, seriously impacting subsequent processing and use.

[0003] Chinese patent application number CN202320821160.7 discloses a silkworm pupa air separation and impurity removal device, comprising a U-shaped box, the four corners of the bottom of the U-shaped box are fixedly connected to support legs, and a drive component for driving the silkworm pupae to move is provided inside the U-shaped box; a side plate is fixedly connected to one side of the U-shaped box, a cylinder is slidably connected to one side of the side plate, a feed port is provided on one side of the cylinder, and multiple detection ports are provided on the other side of the cylinder, a collection box is provided on one side of the U-shaped box, and the collection box is located directly below the detection port, multiple vibrators are provided at the bottom of the cylinder, and a scraping component for scraping the silkworm pupae is provided on one side of the U-shaped box; the impurity removal effect of this impurity removal device is poor and the impurity removal accuracy is low.

[0004] During actual use of the existing air separation and impurity removal device, the white silkworm falls at a fast speed, resulting in a short contact time between the airflow and the white silkworm, and the impurities cannot be fully blown away, resulting in inadequate impurity removal.

[0005] Moreover, the weight of the mixture of white silkworm and impurities fed per unit time varies. If a constant feeding rate is maintained, the impurity removal efficiency will be reduced and the impurity removal effect will be affected.

[0006] In addition, the texture of white silkworm is relatively fragile. After the white silkworm is selected by air, it falls directly into the bottom of the working chamber. The impact force generated may cause the white silkworm to crack or break, thereby reducing the product quality of the white silkworm. Summary of the Invention

The elastic screen is arranged in an inclined shape and is fixedly connected to the inner wall of the working chamber. A second weighing sensor is provided at the inner bottom of the working chamber.

[0016] Preferably, a detection port and a discharge port are provided on the side wall of the working chamber away from the impurity chamber, the top of the detection port is away from the bottom of the elastic screen, and the bottom of the discharge port and the top of the elastic screen are in conflict with each other.

[0017] The present invention also provides a method for removing impurities from a white silkworm wind-removing impurity removal device, which is characterized by comprising the following steps:

[0018] Step 1: Put the white silkworm into the feeding bin. Under the continuous rotation of the material distribution blade, the white silkworm enters the interior of the working chamber through the feeding port;

[0019] Step 2: The white silkworm and impurities collide with the guide plate, and the light impurities fall into the dust collecting chamber along the guide plate, while the heavy impurities and the white silkworm pass through the dust collecting chamber and continue to fall in the working chamber;

[0020] Step 3: When heavy impurities and white silkworms pass through the airflow, the heavy impurities quickly separate from the white silkworms and are carried into the impurity chamber by the airflow, while the white silkworms remain in a falling state and fall onto the elastic screen;

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The present invention provides a guide plate, and the return spring, the fan, the elastic screen and other components cooperate with each other. When the white silkworms and impurities fall, they hit the guide plate, consuming most of the kinetic energy, thereby reducing the falling speed, so that the white silkworms and impurities stay in the airflow for a longer time during the air separation and impurity removal process, and the airflow can fully act on the white silkworms and impurities, thereby improving the air separation and impurity removal effect of the white silkworms; among them, the light impurities have a small rebound distance after hitting the guide plate, and enter the dust collecting chamber along the guide plate, thereby realizing the first-level impurity removal of the white silkworms, further improving the impurity removal effect of the white silkworms; at the same time, the elastic screen is used to absorb the gravitational potential energy generated when the white silkworms fall, thereby preventing the white silkworms from cracking, breaking, etc.

[0026] 2. The present invention arranges a weighing sensor 1, an electric push rod, a material guide plate and other components to cooperate with each other, and controls the output end of the electric push rod to extend or shorten at the same time according to the weight value detected by the weighing sensor 1, and adjusts the inclination angle of the material guide plate accordingly, so that the time that the white silkworm and heavy impurities stay in the air flow is prolonged or shortened, and the feeding rate of the white silkworm and heavy impurities can be adaptively adjusted according to the weight of the heavy impurities, completing the secondary impurity removal of the white silkworm, improving the impurity removal effect and efficiency, and ensuring the quality of the white silkworm and the stability of the impurity removal process.

[0027] 3. The present invention cooperates with other components such as weighing sensor 2, electric push rod, fan and elastic screen. When weighing sensor 2 detects a sudden increase in the weight of heavy impurities at the bottom of the working chamber, the output end of the electric push rod is controlled to extend and the power of the fan is increased at the same time, so that all heavy impurities can be blown into the impurity chamber, achieving thorough secondary impurity removal, effectively separating all heavy impurities, and further improving the overall quality of white silkworm.

[0036] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] Example 1:

[0038] like Figure 1-Figure 3 As shown, this embodiment discloses a white silkworm wind impurity removal device, including a carrier component 1, which can provide stable support for the impurity removal device, and a material distribution component 2 for uniformly feeding the white silkworms is connected to the carrier component 1. A material guide component 3 is provided inside the carrier component 1, and the material guide component 3 is used to reduce the falling speed of the white silkworms and realize the first-level impurity removal of the white silkworms.

[0039] When the white silkworm enters the working chamber 101 through the feeding bin 201, it is easy to cause the material to be blocked or unevenly fed. Figure 3-Figure 4 As shown, the material distribution component 2 includes a feeding bin 201, which provides a stable source of white silkworms for subsequent air separation and impurity removal work. The bottom of the feeding bin 201 is connected to a material distribution pipe 202, and the bottom of the material distribution pipe 202 is provided with a feed inlet 203. The interior of the material distribution pipe 202 is provided with a material distribution leaf 204, and the interior of the material distribution leaf 204 is connected to a connecting shaft 205. One end of the connecting shaft 205 is fixedly connected to the side wall of the material distribution pipe 202, and the other end passes through the material distribution pipe 202 and is connected to a rotating motor 206. During use, the rotating motor 206 rotates at a set rate, and the rotating motor 206 drives the material distribution blade 204 to rotate synchronously through the connecting shaft 205. Then, under the continuous rotation of the material distribution blade 204, the white silkworm enters the interior of the material distribution tube 202, and then the white silkworm enters the interior of the working chamber 101 through the feed port 203. During the rotation process, the material distribution blade 204 can stir the white silkworm in the feeding bin 201 to avoid blockage and agglomeration of the white silkworm during the feeding process.

[0040] When the white silkworm enters the working chamber 101, the falling speed is fast, so that the time when the airflow contacts the white silkworm is short, and then Figure 3-Figure 4 As shown, the carrier assembly 1 includes a working chamber 101, in which the white silkworm completes the air separation and impurity removal work. A fan 102 is provided inside the working chamber 101 to provide continuous airflow. An impurity chamber 105 is connected to the side wall of the working chamber 101 away from the fan 102. A discharge port 107 is provided on the side wall of the impurity chamber 105 away from the fan 102. The impurity chamber 105 is used to collect heavy impurities mixed in the white silkworm, and the heavy impurities are collected through the discharge port 107. An L-shaped plate 103 is provided on the fan 102, and the side wall of the L-shaped plate 103 is fixedly connected to the working chamber 101. The space enclosed between the L-shaped plate 103 and the support plate 301 forms a dust collecting chamber 104. The dust collecting chamber 104 can collect light impurities mixed in the white silkworm. As shown Figure 3 、 Figure 5-Figure 6As shown, the material guide assembly 3 includes a support plate 301, the sidewall of which is fixedly connected to the working chamber 101. The support plate 301 primarily supports the material guide assembly 3. Two sets of electric push rods 302 are provided on one side of the top of the support plate 301. The output ends of the electric push rods 302 are connected to a rotating block 303. When the electric push rods 302 are activated, the output ends drive the rotating block 303 to move. The sidewalls of the rotating block 303 are rotatably connected to the connecting block 304 via bearings. The top of the connecting block 304 is fixedly connected to an inclined material guide plate 305. By controlling the output ends of the two sets of electric push rods 302 to extend or shorten by the same amount, the inclination angle of the material guide plate 305 can be adjusted. Two return springs 306 are connected to the top of the support plate 301, away from the electric push rods 302. The ends of the two return springs 306, away from the support plate 301, are interconnected with the material guide plate 305. The provision of the return springs 306 improves the reset performance of the material guide plate 305. During use, the silkworms and impurities fall through the feed port 203 onto the guide plate 305. Light impurities such as silkworm feces, dust, and mulberry leaves are light in weight, and their rebound distance after hitting the guide plate 305 is negligible. Light impurities fall along the guide plate 305 into the dust collecting chamber 104, completing the first-level impurity removal. Heavy impurities such as mulberry stems, cocoon debris, and stones, as well as the silkworms, are heavy in weight, and their rebound distance after hitting the guide plate 305 is greater. These impurities can then pass through the dust collecting chamber 104 and pass through the air outlet of the fan 102, completing the second-level impurity removal. During the above process, the silkworms and impurities collide with the guide plate 305 as they fall, consuming most of their kinetic energy and reducing their falling speed, facilitating subsequent air separation and impurity removal. At the same time, the guide plate 305 is used to complete the first-level impurity removal, further improving the impurity removal effect of the silkworms.

[0041] The silkworm is relatively fragile. If it falls directly into the bottom of the working chamber 101, the impact force generated may cause the silkworm to crack or break, and then Figure 3-Figure 4 As shown, an elastic screen 108 is provided on the side of the working chamber 101 away from the blower 102. The elastic screen 108 is tilted and fixedly connected to the inner wall of the working chamber 101. A detection port 106 and a discharge port 109 are provided on the side wall of the working chamber 101 away from the impurity chamber 105. The top of the detection port 106 is away from the bottom of the elastic screen 108, and the bottom of the discharge port 109 abuts against the top of the elastic screen 108. After being air-selected, the white silkworms fall onto the elastic screen 108 and are collected through the discharge port 109. The elastic screen 108 can absorb the gravitational potential energy generated by the white silkworms as they fall, preventing them from falling directly to the bottom of the working chamber 101. At the same time, the elastic screen 108 filters out a small amount of heavy impurities that are not carried away by the airflow. The heavy impurities pass through the elastic screen 108 and enter the inner bottom of the working chamber 101, where they are collected by the detection port 106.

[0042] The working principle of the present invention is as follows: the staff puts the white silkworm into the feeding bin 201, and the air separation and impurity removal device is connected to the central control module. The central control module controls the rotating motor 206 to rotate at a set rate. The rotating motor 206 drives the material distribution blade 204 to rotate synchronously through the connecting shaft 205, prompting the white silkworm to enter the material distribution tube 202. Then, under the continuous rotation of the material distribution blade 204, the white silkworm enters the working chamber 101 through the feed port 203, completing the batch feeding of the white silkworm, avoiding the blockage and agglomeration of the white silkworm during the feeding process, thereby effectively ensuring the stability and uniformity of the feeding.

[0043] After the white silkworm and impurities enter the working chamber 101, they hit the guide plate 305, causing the guide plate 305 to compress the return spring 306. The kinetic energy of the white silkworm and impurities is converted into the elastic potential energy of the return spring 306. When the return spring 306 is compressed to the maximum extent, the speed of the white silkworm and impurities drops to zero. Then the return spring 306 begins to restore its deformation, releasing the stored elastic potential energy and converting it into kinetic energy for the white silkworm and impurities to move upward. The white silkworm and impurities leave the surface of the guide plate 305 in an oblique trajectory and begin to move in a parabolic motion. Among them, due to the small weight of light impurities such as silkworm feces, dust, and mulberry leaves, the rebound distance after hitting the guide plate 305 is negligible. The light impurities will fall along the guide plate 305 into the dust collection chamber 104, completing the first-level impurity removal of the white silkworm, further improving the white silkworm removal effect. However, heavy impurities such as mulberry stems, cocoon debris, and stones, as well as the white silkworm, are heavy. After hitting the guide plate 305, they rebound a long distance and then pass through the dust collection chamber 104 and continue to fall within the working chamber 101. After the white silkworm and impurities fall on the guide plate 305, they consume most of their kinetic energy, thereby reducing their falling speed and extending the time they stay in the airflow during the subsequent air separation and impurity removal process.

[0044] The central control module controls the start-up of the fan 102, and the air outlet of the fan 102 will generate a high-speed, directional airflow. When heavy impurities and white silkworms pass through the airflow, the heavy impurities are affected by the buoyancy and impact force of the airflow, and quickly separate from the white silkworms, and are carried into the impurity chamber 105 by the airflow, and then fall to the inner bottom of the impurity chamber 105 under the action of gravity, thereby achieving efficient separation of heavy impurities. The staff collects the separated impurities through the discharge port 107; and since the weight of the white silkworms is relatively large, the force exerted by the airflow on the white silkworms is not enough to push them, and the white silkworms will maintain a stable falling state and fall onto the elastic screen 108. A small amount of heavy impurities that are not carried away by the airflow pass through the elastic screen 108 and enter the inner bottom of the working chamber 101. The staff collects the white silkworms that have been removed through the discharge port 109, observes whether there are any heavy impurities remaining in the white silkworms after air separation through the detection port 106, and collects these heavy impurities.

[0045] The above process is then repeated to remove impurities from subsequent white silkworms, thereby improving the impurity removal effect and efficiency of the white silkworms.

[0046] During the above process, the continuous rotation of the material-distributing blade 204 is utilized to stir the white silkworms in the feeding bin 201, thereby preventing the white silkworms from being blocked or agglomerated during the feeding process and ensuring the uniformity of the feeding of the white silkworms; when the white silkworms and impurities fall, they hit the guide plate 305, consuming most of the kinetic energy, thereby reducing the falling speed, so that the white silkworms and impurities stay in the air flow for a longer time during the air separation and impurity removal process, and the air flow can fully act on the white silkworms and impurities, thereby improving the air separation and impurity removal effect of the white silkworms; among them, the light impurities rebound a small distance after hitting the guide plate 305, and enter the dust collecting chamber 104 along the guide plate 305, thereby realizing the first-level impurity removal of the white silkworms and further improving the impurity removal effect of the white silkworms; at the same time, the elastic screen 108 is utilized to absorb the gravitational potential energy generated when the white silkworms fall, thereby preventing the white silkworms from being cracked or broken.

[0047] Example 2:

[0048] In unit time, there is a difference in the weight of the white silkworm and heavy impurities passing through the airflow. Since the size of the airflow generated by the fan 102 remains constant, in actual use, when the weight of the heavy impurities is relatively large, the heavy impurities cannot be effectively cleaned, and when the weight of the heavy impurities is relatively small, it will lead to a decrease in the impurity removal efficiency. Therefore, embodiment 2 is proposed to solve the above problem.

[0049] A weighing sensor 1 is provided at the inner bottom of the impurity chamber 105. During the impurity removal work of the white silkworm by the blower 102 per unit time, the weighing sensor 1 can detect the weight value of the heavy impurities entering the impurity chamber 105 per unit time, and transmit the signal corresponding to the weight value to the central control module. The central control module compares and analyzes the weight value detected by the weighing sensor 1 with the preset weight value range, and then controls the inclination angle of the guide plate 305, so that the feeding rate of the white silkworm and heavy impurities can be adaptively adjusted according to the weight of the heavy impurities, specifically:

[0050] like Figure 7As shown, when the weight value detected by the weighing sensor 1 is greater than the preset weight value range, it means that the content of heavy impurities is high at this time. The central control module controls the output ends of the two groups of electric push rods 302 to extend the same extension amount at the same time. The electric push rod 302 drives one side of the guide plate 305 to rotate upward, thereby causing the height of the guide plate 305 on this side to increase, while the height of the other side of the guide plate 305 does not change due to the limiting effect of the return spring 306, causing the inclination angle of the guide plate 305 to become smaller, and the white silkworm and impurities leave the guide plate 305 and perform an oblique throwing motion. Their speed in the vertical direction decreases, which prolongs the time that the white silkworm and heavy impurities stay in the air flow, and the weight of the heavy impurities falling into the impurity chamber 105 per unit time decreases, until the weight value of the heavy impurities detected by the weighing sensor 1 per unit time is within the preset weight value range, and the electric push rod 302 is controlled to stop extending, and the heavy impurities can be fully separated, thereby improving the impurity removal effect.

[0051] Similarly, when the weight value detected by the weighing sensor 1 is less than the preset weight value range, it indicates that the content of heavy impurities is low at this time. The central control module controls the output ends of the two sets of electric push rods 302 to shorten the same extension amount at the same time. The electric push rod 302 drives one side of the guide plate 305 to rotate downward, thereby causing the height of the guide plate 305 on this side to decrease, while the height of the other side of the guide plate 305 does not change due to the limiting effect of the return spring 306, causing the inclination angle of the guide plate 305 to increase. The white silkworm and impurities leave the guide plate 305 and perform an oblique throwing motion. Their speed in the vertical direction increases, which shortens the time that the white silkworm and heavy impurities stay in the air flow, and the weight of heavy impurities falling into the impurity chamber 105 per unit time increases, until the weight value of the heavy impurities detected by the weighing sensor 1 per unit time is within the preset weight value range, and the electric push rod 302 is controlled to stop shortening, thereby improving the impurity removal efficiency and ensuring the quality of the white silkworm and the stability of the impurity removal process.

[0052] In the above process, a weighing sensor is used to detect the weight value of heavy impurities entering the impurity chamber 105 per unit time, and the output end of the electric push rod 302 is controlled to extend or shorten at the same time according to the weight value, and the inclination angle of the guide plate 305 is adjusted accordingly, so that the time that the white silkworm and heavy impurities stay in the air flow is extended or shortened, and the feeding rate of the white silkworm and heavy impurities can be adaptively adjusted according to the weight of the heavy impurities, completing the secondary impurity removal of the white silkworm, improving the impurity removal effect and efficiency, and ensuring the quality of the white silkworm and the stability of the impurity removal process.

[0053] Example 3:

[0054] When heavy impurities and white silkworms pass through the airflow, a small amount of heavy impurities may be squeezed and covered by the white silkworms. The heavy impurities cannot be effectively blown up by the airflow, but continue to fall onto the elastic screen 108 along with the white silkworms, and fall into the inner bottom of the working chamber 101 through the elastic screen 108, indicating that the secondary impurity removal using the fan 102 is not thorough, and thus embodiment 3 is proposed to solve the above problem.

[0055] A second weighing sensor is provided at the bottom of the working chamber 101. The weighing sensor is used to detect impurities at the bottom of the working chamber 101, that is, to detect the weight of the heavy impurities passing through the elastic screen 108, and transmit a signal corresponding to the weight value to the central control module. Subsequently, the power of the fan 102 and the inclination angle of the guide plate 305 are controlled so that the weight value does not increase. Specifically:

[0056] like Figure 7 As shown, when the weight value detected by the second weighing sensor suddenly increases, it indicates that the effect of the secondary impurity removal using the fan 102 is not thorough at this time. The central control module controls the output ends of the two groups of electric push rods 302 to extend by the same amount at the same time, causing the inclination angle of the guide plate 305 to become smaller, and the speed of the white silkworm and impurities in the vertical direction to decrease, so that the time that the white silkworm and heavy impurities stay in the airflow is prolonged. At the same time, the central control module controls the power of the fan 102 to gradually increase, causing the airflow intensity to steadily increase. At this time, under the dual effects of extended residence time and increased airflow intensity, the heavy impurities squeezed and covered by the white silkworm can be blown into the impurity chamber 105 until the weight value detected by the second weighing sensor no longer increases, indicating that the fan 102 has achieved thorough secondary impurity removal at this time, and can effectively separate all heavy impurities, and keep the extension length of the output ends of the two groups of electric push rods 302 and the power of the fan 102 unchanged, completing the subsequent impurity removal work of the white silkworm.

[0057] In the above process, when the weighing sensor 2 detects a sudden increase in the weight value of heavy impurities at the bottom of the working chamber 101 passing through the elastic screen 108, the output end of the electric push rod 302 is controlled to extend, and the power of the fan 102 is increased at the same time, so that all heavy impurities can be blown into the impurity chamber 105, achieving thorough secondary impurity removal, and being able to effectively separate all heavy impurities, further improving the overall quality of the white silkworm.

[0058] Example 4:

[0059] This embodiment discloses a method for removing impurities from a white silkworm wind impurity removal device, comprising the following steps:

[0060] Step 1: Put the white silkworm into the feeding bin 201. Under the continuous rotation of the material distribution blade 204, the white silkworm enters the interior of the working chamber 101 through the feeding port 203;

[0061] Step 2: The white silkworm and impurities collide with the guide plate 305. Light impurities fall into the dust collecting chamber 104 along the guide plate 305. Heavy impurities and the white silkworm pass through the dust collecting chamber 104 and continue to fall in the working chamber 101.

[0062] Step 3: When heavy impurities and white silkworms pass through the airflow, the heavy impurities quickly separate from the white silkworms and are carried by the airflow into the impurity chamber 105, while the white silkworms maintain a relatively stable falling state and fall onto the elastic screen 108;

[0063] Step 4: When the weight value detected by the weighing sensor 1 is greater than the preset weight value range, the output ends of the two sets of electric push rods 302 are controlled to extend by the same amount at the same time, so that the inclination angle of the guide plate 305 becomes smaller;

[0064] When the weight value detected by the weighing sensor 1 is less than the preset weight value range, the output ends of the two sets of electric push rods 302 are controlled to shorten and extend by the same amount at the same time, so that the tilt angle of the guide plate 305 becomes larger;

[0065] Step 5: When the weight value detected by the second weighing sensor suddenly increases, the output ends of the two sets of electric push rods 302 are controlled to extend by the same amount at the same time, and the power of the fan 102 is increased at the same time.
