Description

Technical Field

[0001] This utility model relates to the field of stabilizer impurity removal technology, specifically to a device for removing impurities in stabilizer production. Background Technology

[0002] In stabilizer production, the impurity removal process is crucial to ensure product quality and performance. Raw materials often contain metal particles, sand, other chemical impurities, and clumps formed due to moisture. If these impurities are not removed, they will interfere with the chemical properties of the stabilizer, reduce its stability and activity, and affect its performance in downstream products. For example, in plastic processing, impurities may cause defects and performance degradation in plastic products.

[0003] For example, the utility model patent with announcement number CN207056067U discloses a debris removal device for polymer stabilizer production, including a base. A production device is fixedly installed on the top of the base by a first bracket. A discharge pipe is vertically provided at the bottom of the production device. A discharge cylinder is horizontally installed on the top of the base by a second bracket below the discharge pipe. A through hole is opened at the top of the discharge cylinder, and the through hole is connected to the discharge pipe. A discharge port is provided on the side of the discharge cylinder away from the first bracket. This utility model can conveniently and efficiently remove large debris, and can distinguish and collect it. It has a simple structure and is easy to use.

[0004] However, in actual use, it was found that when the raw material is pushed forward by the spiral blade in the discharge cylinder, some of the stabilizer raw material is prone to enter the second collection tank together with larger impurities, resulting in poor separation efficiency between raw material and impurities.

[0005] Meanwhile, although filters can achieve preliminary screening of solid impurities, they cannot effectively remove metal particles mixed in the raw materials, affecting the purity of the finished product and the safety of subsequent processes. Therefore, it is necessary to design a practical and effective impurity removal device for stabilizer production. Utility Model Content

[0006] The purpose of this invention is to provide a device for removing impurities in the production of stabilizers, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for removing impurities in stabilizer production, comprising a processing shell, a circular mounting ring fixedly installed on the top surface of the processing shell, a filter tank disposed inside the circular mounting ring, a shock-absorbing mechanism connected to the filter tank disposed inside the circular mounting ring, a storage tank fixedly installed on the top surface of the filter tank, two sieve plates arranged in an equally spaced array inside the filter tank, a drive screening mechanism connected to the filter tank disposed inside the circular mounting ring, a conveying cylinder fixedly installed inside the processing shell, a feeding hopper fixedly installed on the outer surface of the conveying cylinder, a discharge pipe installed on the bottom surface of the filter tank, and one end of the discharge pipe extending into the inside of the feeding hopper, multiple rectangular grooves arranged in a circumferential array on the inner sidewall of the feeding hopper, and a U-shaped rod slidably connected inside each of the multiple rectangular grooves, a spring rod fixedly installed on the top surface and the ground of the inner surface of the rectangular groove, the telescopic end of the spring rod being fixed to the side of the U-shaped rod, a metal column fixedly installed at one end of the U-shaped rod, and a coil wound on the outer surface of the metal column.

[0008] According to the above technical solution, the drive screening mechanism includes a bearing housing, a main rotating shaft, a motor, a cam, and a semi-circular protrusion. The bearing housing is fixedly installed on the top surface of the processing housing. The main rotating shaft is fixedly installed through the middle of the bearing housing. The motor is fixedly installed on the top surface of the processing housing. The drive end of the motor is fixed to one end of the main rotating shaft. The end of the main rotating shaft away from the motor extends into the interior of the circular mounting ring and is fixed in the middle of the bearing. A cam is fixedly installed on the outer surface of the end of the main rotating shaft that extends into the interior of the circular mounting ring. A semi-circular protrusion corresponding to the cam is provided on the bottom surface of the filter tank.

[0009] According to the above technical solution, the shock-absorbing mechanism includes mounting protrusions, shock-absorbing springs, and support ear plates. Multiple mounting protrusions are evenly arrayed on the inner wall of the circular mounting ring, and shock-absorbing springs are fixedly mounted on the top surface of each of the mounting protrusions. Multiple support ear plates corresponding to the shock-absorbing springs are fixedly mounted on the outer surface of the filter tank, and the top of the shock-absorbing spring is fixed to the bottom surface of the support ear plate.

[0010] According to the above technical solution, a spiral conveying shaft is rotatably connected inside the conveying cylinder. One end of the spiral conveying shaft extends to the outside of the conveying cylinder. A pulley one is fixedly installed on the outer surface of the spiral conveying shaft. A pulley two corresponding to pulley one is fixedly installed on the outer surface of the main rotating shaft. The pulley one and pulley two are connected by a belt.

[0011] According to the above technical solution, three limiting support rods are installed in a circumferential array on the top surface of the processing housing.

[0014] According to the above technical solution, a control cabinet is fixedly installed on one side of the processing housing, and the coil and motor are electrically connected to the control cabinet.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model uses a dual mechanism of driven screening and electromagnetic adsorption. The motor drives the main shaft to rotate the cam. Through the periodic lifting contact between the cam and the semi-circular protrusion on the side wall of the filter tank, the filter tank forms a vertical reciprocating vibration, which facilitates the high-frequency spraying and screening of the stabilizer by the screen plate. This achieves dynamic separation of large particle impurities interception and fine material continuous falling. The coil excitation causes the metal column to adsorb metal particles in the feed material. Combined with the vibration of the filter tank, the metal column is driven to rise and fall slightly, which not only prevents material blockage but also enhances the adsorption efficiency. After power is cut off and demagnetization is performed, the metal impurities are discharged directionally through the screw conveyor shaft. This device can improve the impurity separation and metal removal rate by coordinating mechanical vibration screening and magnetic separation. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a device for removing impurities in stabilizer production, comprising a processing shell 1, a circular mounting ring 2 fixedly installed on the top surface of the processing shell 1, a filter tank 3 disposed inside the circular mounting ring 2, and a damping mechanism 4 connected to the filter tank 3 disposed inside the circular mounting ring 2, and three limiting support rods 18 arranged in a circumferential array on the top surface of the processing shell 1; the damping mechanism 4 facilitates the subsequent up-and-down movement of the filter tank 3, thus facilitating the subsequent filtration and impurity removal of the stabilizer inside the filter tank 3, and the three limiting support rods 18 improve the stability of the filter tank 3, preventing it from swaying left and right during up-and-down vibration, thereby improving stability.

[0025] Please see Figure 1-3 The shock-absorbing mechanism 4 includes mounting protrusions 401, damping springs 402, and support ear plates 403. Multiple mounting protrusions 401 are evenly spaced on the inner wall of the circular mounting ring 2, and damping springs 402 are fixedly mounted on the top surface of each mounting protrusion 401. Multiple support ear plates 403 corresponding to the damping springs 402 are fixedly mounted on the outer surface of the filter tank 3, with the top of the damping springs 402 fixed to the bottom surface of the support ear plates 403. Through the coordinated design of the mounting protrusions 401, damping springs 402, and support ear plates 403, stable support and dynamic shock absorption adjustment of the filter tank 3 can be achieved. When the filter tank 3 is driven by a motor to perform vertical reciprocating motion, the damping springs 402 provide buffer protection while converting mechanical vibration energy into controllable elastic deformation. This reduces the overall impact of equipment operation and, through periodic extension and contraction, drives the filter tank 3 to generate regular micro-vibrations, thereby enhancing the separation efficiency of the stabilizer and impurities inside the tank.

[0026] Please see Figure 1-3A storage tank 5 is fixedly installed on the top surface of the filter tank 3. A transparent observation window 19 is fixedly installed on the outer surface of the storage tank 5. Two sieve plates 6 are installed in an equally spaced array inside the filter tank 3. A drive screening mechanism 7 connected to the filter tank 3 is set inside the circular mounting ring 2. The storage tank 5 facilitates the entry of the stabilizer to be removed into the filter tank through the feed pipe at the top. This allows the stabilizer to be stored so that it can continuously enter the filter tank 3 and be screened and removed through the cooperation of the drive screening mechanism 7 and the two sieve plates 6. The two sieve plates 6 have different apertures, which facilitates the filtration and removal of impurities of different diameters. A maintenance plate is installed on the outer surface of the filter tank 3, and a discharge pipe is installed on one side of the maintenance plate. When the valve on the discharge pipe is opened, the impurities screened by the sieve plates 6 can be discharged, improving convenience.

[0027] Please see Figure 1-6 The drive screening mechanism 7 includes a bearing housing 701, a main rotating shaft 702, a motor 703, a cam 704, and a semi-circular protrusion 705. The bearing housing 701 is fixedly installed on the top surface of the processing housing 1. The main rotating shaft 702 is fixedly installed through the middle of the bearing housing 701. The motor 703 is fixedly installed on the top surface of the processing housing 1. The drive end of the motor 703 is fixed to one end of the main rotating shaft 702. The end of the main rotating shaft 702 away from the motor 703 extends into the interior of the circular mounting ring 2 and is fixed in the middle of the bearing. The outer surface of the end of the main rotating shaft 702 extending into the interior of the circular mounting ring 2 is fixedly installed with a cam 704. The bottom surface of the filter tank 3 is provided with a semi-circular protrusion corresponding to the cam 704. The device features a shaped protrusion 705. During operation, the motor 703 drives the main shaft 702 to rotate, which in turn drives the cam 704 fixed at the shaft end to rotate synchronously. When the cam 704 rotates from a low phase to a high phase, its contour contacts the semi-circular protrusion 705 on the side wall of the filter tank 3 and applies a lifting force, forcing the filter tank 3 to rise vertically. After the cam 704 continues to rotate until it loses contact, the filter tank 3 falls rapidly under its own weight, thus forming a periodic vertical reciprocating motion. This causes the stabilizer inside the filter tank 3 to generate a high-frequency spraying and stratification effect on the surface of the sieve plate 6, which promotes the fine particles to fall through the sieve holes, while large impurities are intercepted and retained by the sieve plate, thereby achieving continuous and efficient separation and impurity removal operations.

[0028] Please see Figure 1-2 The processing housing 1 is fixedly installed with a conveying cylinder 8, and a feeding hopper 9 is fixedly installed on the outer surface of the conveying cylinder 8. The bottom surface of the filter tank 3 is equipped with a discharge pipe, and one end of the discharge pipe extends into the inside of the feeding hopper 9. The discharge pipe facilitates the introduction of the stabilizer after filtration and impurity removal into the inside of the feeding hopper 9, and the conveying cylinder 8 facilitates the subsequent discharge of the stabilizer after impurity removal.

[0029] Please see Figure 1-3The conveying cylinder 8 is rotatably connected to a screw conveyor shaft 15. One end of the screw conveyor shaft 15 extends to the outside of the conveying cylinder 8. A pulley 16 is fixedly installed on the outer surface of the screw conveyor shaft 15. A pulley 17 corresponding to the pulley 16 is fixedly installed on the outer surface of the main rotating shaft 702. The pulley 16 and the pulley 17 are connected by a belt. A discharge guide plate 20 is fixedly installed on the outer surface of the conveying cylinder 8. The end of the discharge guide plate 20 away from the conveying cylinder 8 extends to the outside of the processing housing 1. When the main rotating shaft 702 rotates under the drive of the motor 703, it will also drive the pulley 16 to rotate. This facilitates the rotation of the pulley 17 and the screw conveyor shaft 15 under the drive of the belt, so that the stabilizer after impurity removal inside the conveying cylinder 8 can be discharged through the discharge guide plate 20 for further processing.

[0030] Please see Figure 1-5 The inner wall of the feed hopper 9 has multiple rectangular grooves 10 arranged in a circular array, and each of the rectangular grooves 10 has a U-shaped rod 11 slidably connected inside. A spring rod 12 is fixedly installed on the top surface and the ground surface of each rectangular groove 10. The telescopic end of the spring rod 12 is fixed to the side of the U-shaped rod 11. A metal column 13 is fixedly installed at one end of the U-shaped rod 11, and a coil 14 is wound around the outer surface of the metal column 13. A control cabinet 21 is fixedly installed on one side of the processing housing 1. The coil 14 and the motor 703 are electrically connected to the control cabinet 21. The control cabinet 21 allows the internal control elements to control the start and stop of the coil 14 and the motor 703. The control elements can be a PLC or a microcontroller control system, allowing for precise adjustment. The control coil 14 is switched on and off, and the motor 703 is started and stopped. When the coil 14 is energized, the metal column 13 is excited and magnetized to form a strong magnetic field, which adsorbs the metal particles in the stabilizer falling from the feed hopper 9. During the adsorption stage, the vertical vibration of the filter tank 3 drives the discharge pipe to move up and down synchronously, causing the U-shaped rod 11 to periodically contact the pipe. Under the elastic reset action of the spring rod 12, the metal column 13 will rise and fall in a regular manner, which not only avoids material accumulation and blockage, but also enhances the capture efficiency of metal particles. After the adsorption is completed, the coil 14 is de-energized and demagnetized. The particles retained on the surface of the metal column 13 are detached under the assistance of gravity and vibration and fall into the conveying cylinder 8, and are directionally discharged by the screw conveyor shaft 15, realizing the dynamic separation, collection and automated cleaning of metal impurities.
