Abstract

This utility model relates to the field of chemical material processing technology, and provides a chemical material screening device for easy and rapid collection, including a support frame, with an external feeding sleeve fixed inside the support frame. During operation, the fine material separated during the rotary screening process enters the inlet of the secondary automated collection mechanism through the screening holes and the external feeding sleeve, and is then automatically transported to the secondary collection box by an electric conveyor belt, achieving automated collection of the secondary fine material. Furthermore, after an infrared sensor installed on the inner wall of the inlet detects that no more material is being discharged, a vacuum pump starts, drawing the primary coarse material from the separation point into the primary collection tank through a rotary joint for collection. This achieves automated collection of the screened primary coarse material, thus achieving automated and rapid collection of the two materials separated at the rotary screening point without manual intervention to switch collection containers, saving time associated with manual collection.

Description

Technical Field

[0001] This utility model relates to the field of chemical material processing technology, and in particular to a chemical material screening device that facilitates rapid material collection. Background Technology

[0002] Chemical materials come in a wide variety of forms, including metallic materials, inorganic non-metallic materials, organic polymer materials, and composite materials. During the production and processing of chemical materials, screening equipment is often required. Screening can separate materials of different particle sizes to meet the precise requirements for particle size in production, and can also remove impurity particles from the materials to ensure the purity of the chemical materials. To this end, patent CN214347864U discloses a chemical material screening device, including a base, a material box, a door panel, a track, and a material collection box. The material box is fixed to one side of the top of the base, and the door panel is hinged to one side of the surface of the material box. A bracket is fixed to one side of the top of the material box, and a storage box is fixed to one side inside the bracket. A drive motor is installed on the outer wall of one side of the material box. Tracks are fixed to both sides of the bottom of the material box, and a slider is slidably installed on one side of the track surface. A material collection box is installed on one side of the top of the slider. A control panel is installed on one side of the surface of the bracket. The output terminal of the microcontroller inside the control panel is electrically connected to the input terminal of the drive motor. This chemical material screening device is equipped with a storage tank and a secondary mounting base. The opening and closing of the material outlet at the bottom of the storage tank can be controlled by an electric push rod and a first baffle plate to prevent the chemical material from falling too fast or too slow, and to reasonably control the falling speed of the chemical material to avoid material accumulation inside the device. By being equipped with a driven gear disc and a drive motor, when the chemical material falls on the surface of the fine screen, the drive gear drives the driven gear disc to rotate. At this time, the connecting block rotates around the center of the driven gear disc. Since the connecting block is stuck inside the limit frame, the rotational motion of the connecting block can be converted into the vertical reciprocating motion of the connecting rod. The fixed block and the fine screen can vibrate up and down under the drive of the connecting rod, thereby screening the chemical material and enhancing the material screening quality of the device. The aforementioned chemical material screening device, while equipped with a storage tank and auxiliary mounting base, allows the opening and closing of the material outlet at the bottom of the storage tank to be controlled by an electric push rod and a first baffle plate. This prevents the chemical material from falling too quickly or too slowly, ensuring proper control of the material's falling speed and avoiding material accumulation inside the device. Through the installation of a driven gear disc and a drive motor, when the chemical material falls onto the surface of the fine screen, the drive gear drives the driven gear disc to rotate. At this time, the connecting block rotates around the center of the driven gear disc. Because the connecting block is locked inside the limit frame, the connecting... The rotational motion of the connecting block can be converted into the vertical reciprocating motion of the connecting rod. The fixed block and the fine screen can vibrate up and down under the drive of the connecting rod, thereby screening chemical materials and enhancing the material screening quality of the device. However, it only has a single material collection box, which can only collect the screened materials uniformly and cannot collect fine and coarse materials separately. It requires manual sorting afterward, which affects the processing efficiency. Furthermore, the machine needs to be stopped when the collection box is replaced manually, which can easily lead to production interruption and cannot achieve continuous and rapid material collection. Therefore, it is necessary to design a chemical material screening device that can facilitate rapid material collection. Utility Model Content

[0003] The purpose of this invention is to provide a chemical material screening device that facilitates rapid material collection, thereby addressing the shortcomings of existing chemical material screening devices that cannot achieve automated classification and collection and have low working efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a chemical material screening device that facilitates rapid material collection, including a support frame; The support frame has an external feeding sleeve fixed inside, and a rotary screening mechanism is movably connected inside the external feeding sleeve. The rotary screening mechanism includes a machine box fixed to one side of the external feeding sleeve, a positioning base plate fixed to the other side of the external feeding sleeve, and a screening tank rotatably connected between the machine box and the positioning base plate. A primary collection tank is installed on the positioning base plate, and a feeding hopper that matches the screening tank body is fixed on the top of the support frame. A vibration motor is installed on the outer wall of the feeding hopper. The bottom of the support frame is equipped with a secondary automated material collection mechanism, which includes an electric conveyor belt fixed inside the bottom of the support frame. The output end of the electric conveyor belt is equipped with a secondary material collection box. The top of the electric conveyor belt is fitted with an arc-shaped dust cover, and the top of the arc-shaped dust cover is provided with an inlet that communicates with the external feeding sleeve.

[0005] Furthermore, the outer wall of the screening tank is uniformly provided with screening holes, and both the screening tank and the outer feeding sleeve are coated with a Teflon anti-stick layer. The angle between the screening tank and the horizontal plane is 20°.

[0006] Furthermore, a second feeding solenoid valve is installed at the middle position of the top of the screening tank, and a first feeding solenoid valve matching the second feeding solenoid valve is installed at the bottom of the feeding hopper.

[0007] Furthermore, a hollow bearing is provided between the screening tank and the positioning base plate.

[0008] Furthermore, a rotary joint is connected between the side of the primary collection tank away from the air pump and the screening tank body, and the horizontal center line of the rotary joint, the hollow bearing and the screening tank body are on the same straight line.

[0009] Furthermore, a first stepper motor is installed on the outer wall of the housing, and the output end of the first stepper motor is connected to a drive gear, which is meshed with a driven gear.

[0010] Furthermore, the side of the screening tank away from the positioning base plate is connected to the driven gear, and an angle encoder is installed between the driven gear and the screening tank.

[0011] Furthermore, a second stepper motor is installed on the outer wall of the electric conveyor belt, and an air pump is installed on the side of the primary collection tank away from the positioning base plate, with a filter screen provided at the input end of the air pump.

[0012] Furthermore, an infrared sensor is installed on the inner wall of the feed inlet.

[0013] The present invention provides a chemical material screening device that facilitates rapid material collection, the advantages of which are: Equipped with a secondary automated collection mechanism, the screening tank is positioned with the end closest to the secondary automated collection mechanism at the bottom. Due to gravity, the fine material separated during the rotary screening process enters the inlet of the secondary automated collection mechanism through the screening holes and the external feeding sleeve. It is then automatically transported to the secondary collection box via an electric conveyor belt, achieving automated collection of the secondary fine material. Furthermore, when the infrared sensor installed on the inner wall of the inlet detects that no more material is being discharged, the vacuum pump on the primary collection tank at the upper end of the secondary automated collection mechanism starts, drawing the primary coarse material from the separation point into the primary collection tank for collection through a rotary joint. This achieves automated collection of the screened primary coarse material. Thus, by automatically and quickly collecting the two materials separated at the rotary screening point, no manual intervention is required to switch the collection containers, saving time for manual material collection. Equipped with a screening tank, the tank rotates smoothly inside the external feeding sleeve via a reduction gear driven by a drive gear. During rotational screening, the material is fully agitated and dispersed within the tank, preventing dead zones caused by localized accumulation and ensuring that all material contacts the screening holes for more thorough separation of fine materials. Furthermore, the continuous rolling of the material during rotation makes it less prone to adhering to the edges of the screening holes. Combined with a Teflon anti-sticking layer, this provides excellent anti-clogging performance. Moreover, an angle encoder monitors the rotation angle and speed of the screening tank in real time, feeding back to the control system for precise control of the screening process. This system can accommodate chemical materials of different particle sizes and flowability. Coarse particles are screened at low speeds to ensure accuracy, while fine powders are screened at high speeds to improve separation efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figures 1-5 The present invention provides a chemical material screening device that facilitates rapid material collection, including a support frame 2.

[0018] Reference Figures 1-5 An external feeding sleeve 8 is fixed inside the support frame 2, and a rotary screening mechanism 7 is movably connected inside the external feeding sleeve 8. The rotary screening mechanism 7 includes a housing 706 fixed to one side of the external feeding sleeve 8, a positioning base plate 6 fixed to the other side of the external feeding sleeve 8, and a screening tank 705 rotatably connected between the housing 706 and the positioning base plate 6. A primary collection tank 10 is installed on the positioning base plate 6, and a feeding hopper 3 that matches the screening tank 705 is fixed on the top of the support frame 2. A vibration motor 4 is installed on the outer wall of the feeding hopper 3. The bottom end of the support frame 2 is equipped with a secondary automated material collection mechanism 1, and the secondary automated material collection mechanism 1 includes an electric conveyor belt 103 fixed inside the bottom end of the support frame 2. The output end of the electric conveyor belt 103 is equipped with a secondary material collection box 101. The top of the electric conveyor belt 103 is fitted with an arc-shaped dust cover 104. The top of the arc-shaped dust cover 104 is provided with an inlet 105 that communicates with the external feeding sleeve 8. A second stepper motor 102 is installed on the outer wall of the electric conveyor belt 103, and an air pump 9 is installed on the side of the primary collection tank 10 away from the positioning base plate 6, and a filter screen is provided at the input end of the air pump 9. The outer wall of the screening tank 705 is uniformly provided with screening holes 701, and both the screening tank 705 and the outer feeding sleeve 8 are coated with a Teflon anti-stick layer. The angle between the screening tank 705 and the horizontal plane is 20°. An infrared sensor 106 is installed on the inner wall of the feed inlet 105.

[0019] An external power supply is used. Chemical materials are fed into the feeding hopper 3, and the vibration motor 4 on the outer wall of the feeding hopper 3 is activated to prevent the chemical materials from accumulating and clogging inside the hopper. Then, through the first feeding solenoid valve 5 and the second feeding solenoid valve 702, which are in the correct position and open, the chemical materials are sent into the screening tank 705 to complete the rotary screening process. The angle between the screening tank 705 and the horizontal plane is 20°. The end of the screening tank 705 closest to the secondary automated collection mechanism 1 is at the bottom. Based on gravity, the fine materials separated during the rotary screening process can easily enter the inlet 105 on the secondary automated collection mechanism 1 through the screening hole 701 and the external feeding sleeve 8, and then enter the electric conveyor belt 103 and be conveyed forward into the interior of the secondary collection box 101 to realize the automated collection of secondary fine materials. At the same time, the inlet 105 contains... After the infrared sensor 106 mounted on the wall detects that no more secondary fine material is discharged from the screening tank 705, the vacuum pump 9 on the primary collection tank 10 at the upper end of the secondary automated collection mechanism 1 starts, drawing the primary coarse material from the separation point into the primary collection tank 10 for collection through the rotary joint 703. This achieves automated collection of the screened primary coarse material, thereby enabling the automated and rapid collection of the two materials at the rotary screen separation point without the need for manual intervention to switch collection containers, saving time for manual material collection. When workers or robots feed material through the feeding hopper 3, the infrared sensor 106 automatically triggers the coarse material collection process, which not only avoids the material that has completed screening and separation from remaining inside the screening mechanism and interfering with subsequent separation, but also saves material unloading time, improves processing efficiency, and optimizes the convenience of material unloading operations.

[0020] Reference Figures 1-3 A second feeding solenoid valve 702 is installed at the middle position of the top of the screening tank 705, and a first feeding solenoid valve 5 matching the second feeding solenoid valve 702 is installed at the bottom of the feeding hopper 3. A hollow bearing 704 is provided between the screening tank 705 and the positioning base plate 6; A rotary joint 703 is connected between the side of the primary collection tank 10 away from the air pump 9 and the screening tank 705. The horizontal center lines of the rotary joint 703, the hollow bearing 704 and the screening tank 705 are on the same straight line. The outer wall of the housing 706 is equipped with a first stepper motor 707, and the output end of the first stepper motor 707 is connected to a drive gear 709, and a driven gear 708 is meshed on the drive gear 709. The side of the screening tank 705 away from the positioning base plate 6 is connected to the driven gear 708, and an angle encoder 710 is installed between the driven gear 708 and the screening tank 705.

[0021] When an external power supply is connected, the first stepper motor 707 on the outer wall of the housing 706 starts, driving the drive gear 709 to rotate. The drive gear 709 drives the meshing driven gear 708 to rotate, which in turn drives the screening tank 705 to rotate inside the outer feeding sleeve 8. The screening holes 701 on the outer wall of the screening tank 705 classify and screen the material. Material that meets the particle size requirements passes through the screening holes 701 and enters the outer feeding sleeve 8, while coarse material that does not pass through remains in the screening tank 705. When the screening tank 705 rotates, the material is fully agitated and dispersed inside the tank, avoiding localized mixing. The screen eliminates dead corners caused by material buildup, ensuring all materials can contact the screening holes 701 for more thorough separation of fine materials. The continuous rolling of materials during rotation prevents them from adhering to the edges of the screening holes 701. Combined with a Teflon anti-stick layer, this provides excellent anti-clogging performance. Furthermore, the angle encoder 710 monitors the rotation angle and speed of the screening tank 705 in real time, feeding back to the control system for precise control of the screening process. This allows for matching with chemical materials of different particle sizes and flowability; low speed ensures screening accuracy for coarse particles, while high speed improves separation efficiency for fine powder materials.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
