Description

Technical Field

[0001] This utility model relates to the technical field of feed screening devices, specifically a feed screening device for an extraction tank. Background Technology

[0002] Extraction tanks are crucial in bio-extraction processes, especially in the pharmaceutical, food, and cosmetic industries. During bio-extraction, these tanks need to process large quantities of raw materials, which often contain impurities, dust, and other unwanted components. To improve extraction efficiency and product quality, the raw materials need to be screened before extraction to remove impurities and dust.

[0003] Chinese Patent No. CN221966056U discloses a feeding and screening device for an extraction tank, including a base, a support on the top of the base, a spiral guide block integrally machined inside the support, a first frame, a second frame, and a third frame symmetrically arranged on the surface of the support, a first screen, a second screen, and a third screen respectively installed inside the first frame, the second frame, and the third frame, a first through hole with four holes at one end of the support, and second through holes symmetrically arranged on the surfaces of the first frame, the second frame, and the third frame, a rod inserted into the first and second through holes at one end of the support, a limit nut threaded to the other end of the rod, a rotating rod on the top of the base and inside the support, a rotating sleeve fixedly fitted onto the surface of the rotating rod, and a cleaning brush fixedly fitted onto the surface of the rotating sleeve.

[0004] The above technical solution has the following drawbacks: Although a three-layer screen is designed for screening different particle sizes, the arrangement of the screens and the design of the spiral guide block may affect the screening efficiency. If the guiding speed of the spiral guide block is too fast, the material may remain on the screen for too short a time, resulting in insufficient screening.

[0005] To address this issue, we propose a feeding screening device for extraction tanks. Utility Model Content

[0006] The purpose of this invention is to provide a feeding and screening device for extraction tanks to solve the problem of insufficient screening accuracy mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a feeding and screening device for an extraction tank, comprising a base, a support, and a top seat. Universal wheels are fixedly connected to the bottom surface of the base. The bottom of the support is fixedly connected to the upper surface of the base. The top seat is fixedly connected to the upper surface of the support. A feeding trough is provided in the middle of the top seat. A feeding bin is provided above the feeding trough. A screening device is provided on the support.

[0008] The screening device includes a screening unit and a feeding unit;

[0009] The screening unit includes a first connecting seat, a second connecting seat, a guide rod, a connecting block, a support rod, a motor, a rotating shaft, a connecting rod, a connecting shaft, a movable rod, a fixed seat, a connecting groove, and a screening box. The first and second connecting seats have guide grooves inside. The guide rod is fixedly connected inside the guide groove. One end of the connecting block is slidably connected to the guide rod, and the other end of the connecting block is fixedly connected to the front and rear sides of the screening box. The support rod is fixedly connected between two supports on the front. The motor is fixedly connected to the front of the support rod via a support plate. The motor output end is connected to the rotating shaft via a coupling. The rotating shaft is fixedly connected to one end of the connecting rod. The other end of the connecting rod is connected to the movable rod via a connecting strip. The movable rod is connected to the connecting groove, which is located in the fixed seat. The fixed seat is fixedly connected above the screening box below.

[0010] Preferably, the feeding unit includes a groove, a slider, an electric push rod, and a connecting shaft. The connecting shaft is fixedly connected to the left sides of connecting seat one and connecting seat two, respectively. The left sides of connecting seat one and connecting seat two are rotatably connected to the left support via a rotating shaft. The right sides of connecting seat one and connecting seat two are fixedly connected to the slider. The bottom of the slider is connected to the output end of the electric push rod. The slider is slidably connected to the groove, which is located on the right support. The bottom of the electric push rod is fixedly connected to the bottom surface inside the groove. By extending and retracting the electric push rod, the slider can slide within the groove, thereby changing the position of connecting seat one and connecting seat two, and thus adjusting the tilt angle of the screening box.

[0011] Preferably, a discharge chute is provided on the left side of the screening box, an extension block is fixedly connected to the lower left side of the screening box, the bottom ends of the baffle plate are rotatably connected to the extension block through adapter strips, and magnetic blocks are provided on the right side of the baffle plate and the left side of the screening box. The design of the discharge chute and the baffle plate enables the screened material to be discharged in an orderly manner.

[0012] Preferably, the screening device has three sets, which are equidistantly connected to the support. The arrangement of multiple screening devices improves the screening capacity.

[0013] Preferably, the material distribution plate is arranged in three sets on the lower left side of each screening device. The design of the material distribution plate can guide the screened material into different collection containers to achieve classified collection of materials.

[0014] Preferably, the mesh size of the screening box gradually decreases from top to bottom, enabling multi-stage screening and ensuring that materials of different sizes can be effectively separated. As the materials fall, they pass through the mesh size of the screen in sequence, thereby achieving fine grading and screening, and improving the accuracy and efficiency of screening.

[0015] Preferably, the screening box is equipped with a vibrator. Vibration allows the material to pass through the screen more quickly, reducing clogging. It also helps to shake off small particles attached to the screen, keeping the screen unobstructed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] To address the issue of excessively high feed speed of the spiral guide block potentially leading to insufficient material retention time on the screen and inadequate screening, please refer to [link to relevant documentation]. Figures 1-5 This utility model provides a technical solution: a feeding and screening device for an extraction tank, including a base 301, a support 2, and a top seat 302. The base 301 has casters 304 fixedly connected to its bottom surface, facilitating flexible movement of the device according to work requirements. The bottom of the support 2 is fixedly connected to the upper surface of the base 301, and the top seat 302 is fixedly connected to the upper surface of the support 2. The support 2 serves as a supporting structure, connecting the base 301 and the top seat 302, ensuring the stable installation of components such as the screening device and the feeding hopper 1. A feeding trough 303 is provided in the middle of the top seat 302, serving as a channel for materials to enter the screening device, ensuring smooth material entry into the screening process. The feeding hopper 1 is located above the feeding trough 303, and the screening device is mounted on the support 2.

[0028] The screening device includes a screening unit and a feeding unit;

[0029] The screening unit includes a first connecting seat 401, a second connecting seat 402, a guide rod 403, a connecting block 404, a support rod 405, a motor 406, a rotating shaft 407, a connecting rod 408, a connecting shaft 409, a movable rod 410, a fixed seat 411, a connecting groove 412, and a screening box 6. The first connecting seat 401 and the second connecting seat 402 have guide grooves inside. The guide rod 403 is fixedly connected inside the guide groove. One end of the connecting block 404 is slidably connected to the guide rod 403, and the other end of the connecting block 404 is fixedly connected to the support rod 405. On the front and rear sides of the screening box 6, support rods 405 are fixedly connected between the two front brackets 2. A motor 406 is fixedly connected to the front of the support rod 405 via a support plate. The output end of the motor 406 is connected to a rotating shaft 407 via a coupling. The rotating shaft 407 is fixedly connected to one end of a connecting rod 408. The other end of the connecting rod 408 is connected to a movable rod 410 via a connecting strip. The movable rod 410 is connected to a connecting groove 412, which is located in a fixed seat 411. The fixed seat 411 is fixedly connected to the bottom of the screening box 6. The motor 406 drives the movement of the connecting rod 408 and the movable rod 410, causing the screening box 6 to vibrate and reciprocate during screening, achieving effective material separation. Guide rods 403 and connecting blocks 404 ensure the stability of the screening box 6 during vibration.

[0030] Three sets of screening devices are equidistantly connected to the support 2, enabling multi-stage screening and ensuring effective separation of materials of different sizes. Three sets of distribution plates 5 are located on the lower left side of each screening device, guiding the screened material into different collection containers for categorized collection and subsequent processing. The mesh size of the screening box 6 gradually decreases from top to bottom. A vibrator is installed inside the screening box 6 to further improve screening efficiency.

[0031] Example 2:

[0032] Based on Embodiment 1, in order to better remove the screened material from the screening box, the device is equipped with a feeding unit. The feeding unit includes a groove 201, a slider 202, an electric push rod 203, and a connecting shaft 409. The connecting shaft 409 is fixedly connected to the left side of the first connecting seat 401 and the second connecting seat 402, respectively. The left side of the first connecting seat 401 and the second connecting seat 402 is rotatably connected to the left support 2 via a rotating shaft 407. The right side of the first connecting seat 401 and the second connecting seat 402 is fixedly connected to the slider 202. The bottom of the slider 202... The part is connected to the output end of the electric push rod 203, and the slider 202 is slidably connected to the groove 201. The groove 201 is opened in the right bracket 2. The bottom of the electric push rod 203 is fixedly connected to the bottom surface inside the groove 201. By extending and retracting the electric push rod 203, the slider 202 is driven to slide in the groove 201, thereby changing the position of the connecting seat 1 401 and the connecting seat 2 402, and thus adjusting the tilt angle and discharge direction of the screening box 6, so that the screened material can be smoothly taken out from the screening box 6, improving the convenience and flexibility of operation.

[0033] To prevent material leakage through the discharge chute during screening, a baffle assembly is installed on the left side of the screening box. A discharge chute 601 is located on the left side of the screening box 6. An extension block 602 is fixedly connected to the lower left side of the screening box 6. The bottom ends of a baffle plate 604 are rotatably connected to the extension block 602 via adapter strips 603. Magnetic blocks 605 are installed on the right side of the baffle plate 604 and the left side of the screening box 6. The baffle plate 604 is rotatably connected to the extension block 602 via the adapter strips 603, allowing the discharge chute 601 to be closed when needed to prevent material leakage during screening. The magnetic blocks 605 facilitate the fixing and opening of the baffle plate 604, improving operational convenience and safety.

[0034] Working principle: After the material to be screened is placed in the feeding hopper 1, the screening device is started. The motor 406 drives the rotating shaft 407 to rotate via a coupling. The rotation of the rotating shaft 407 drives the connecting rod 408 and the movable rod 410 to reciprocate. The movement of the movable rod 410 is transmitted to the screening box 6 through the connecting groove 412 and the fixed seat 411, causing it to perform left and right reciprocating screening. The vibrator further improves the screening efficiency and ensures effective separation of materials. The mesh size of the screen in the screening box 6 gradually decreases from top to bottom, realizing multi-stage screening function.

[0035] After the screening process is completed, the baffle plate 604 is opened, and the feeding unit is started. The extension and retraction of the electric push rod 203 causes the slider 202 to slide within the groove 201. The sliding of the slider 202 changes the position of the connecting seat 1 401 and the connecting seat 2 402, thereby adjusting the tilt angle and discharge direction of the screening box 6. By adjusting the tilt angle, the discharge speed and direction of the material can be easily controlled, facilitating the smooth removal of the screened material. The screened material is guided to different collection containers by the distribution plate 5.
