Description

Technical Field

[0001] This utility model relates to the field of impurity removal equipment technology, and in particular to an impurity removal device for plastic granules. Background Technology

[0002] During the production and processing of plastic granules, due to the influence of various factors such as raw material characteristics and production processes, plastic granules often contain particles of different sizes and impurities, which can affect the quality of subsequent processed products and reduce the performance and stability of the products. Currently, most equipment for removing impurities from plastic granules uses only a single-layer screen. However, a single-layer screen can only achieve simple impurity removal and is difficult to accurately separate and recycle plastic granules of different sizes and impurities. The actual impurity removal effect is not ideal, and some large clumps and impurities remain in the qualified granules, requiring subsequent manual sorting, which increases the actual workload. Therefore, to solve this problem, designing an impurity removal device for plastic granules is something we need to consider. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for removing impurities from plastic granules. Addressing usage issues, it incorporates an impurity removal mechanism. By activating a vibrating motor, in conjunction with springs, a sieve plate, and a screen, it can efficiently achieve multi-stage impurity removal from plastic granules, reducing workload. It also includes a lifting mechanism; by controlling the lifting of the U-shaped lifting plate, it can automatically classify and recycle the removed materials, demonstrating good practicality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for removing impurities from plastic granules includes a housing with a fixed plate fixedly connected to the inner wall of the housing; a removal mechanism including two sieve plates inclined above the fixed plate, with multiple connecting rods fixedly connected between the two sieve plates, each sieve plate having a screen, the lower end of the lower sieve plate being elastically connected to the upper end of the fixed plate by multiple springs, and a vibration motor installed at the lower end of the lower sieve plate; and a lifting mechanism including a telescopic rod installed at the bottom of the housing, with a U-shaped lifting plate fixedly connected to the telescopic end of the telescopic rod, the vertical portions on both sides of the U-shaped lifting plate penetrating the fixed plate and fitting against the side walls of the two sieve plates, and discharge channels being formed on the vertical portions on both sides of the U-shaped lifting plate.

[0005] Preferably, the fixing plate has a drainage groove in the middle, and the telescopic rod is a hydraulic telescopic rod.

[0006] Preferably, the front and rear sides of the two sieve plates are in contact with the front and rear inner walls of the housing, and the front and rear sides of the U-shaped lifting plate are in contact with the front and rear inner walls of the housing, respectively.

[0007] Preferably, two guide rods are fixedly connected between the lower end of the fixed plate and the inner bottom of the housing, and both guide rods are slidably connected to the lower end of the U-shaped lifting plate.

[0008] Preferably, the upper end of the shell is provided with a feed inlet, and the left and right sides of the shell are provided with discharge outlets.

[0009] Preferably, a sliding door is rotatably provided on the front side of the housing, and a controller is installed on the front side of the housing.

[0010] Compared with the prior art, the advantages of this utility model are as follows: An impurity removal mechanism is installed. By activating a vibrating motor and multiple springs, the two screen plates and their meshes continuously vibrate, thus efficiently achieving multi-stage impurity removal of plastic granules. Compared to traditional single-layer screens, this improves the actual impurity removal effect and reduces the workload of workers. A lifting mechanism is also included. By controlling the telescopic rod to move the U-shaped lifting plate downward, in conjunction with the discharge chute and impurity discharge chute, various materials can be automatically classified and recycled. The entire classification and recycling process is convenient, eliminating the need for manual sorting, effectively reducing the workload of recycling, and greatly improving the practicality of the entire device.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-4 A device for removing impurities from plastic granules includes a housing 1. A fixing plate 2 is fixedly connected to the inner wall of the housing 1. A discharge channel 11 is opened in the middle of the fixing plate 2. The discharge channel 11 allows dust and small plastic fragments that have passed through two screens 5 to pass through and fall into the inner bottom of a U-shaped lifting plate 9. An inlet 13 is provided at the upper end of the housing 1. Discharge outlets 14 are provided on both the left and right sides of the housing 1. The discharge outlet 14 on the left side is used to recover large clumps of plastic granules, and the discharge outlet 14 on the right side is used to recover qualified plastic granules. A sliding door 15 is rotatably provided on the front side of the housing 1. When opened, it can recover dust and small plastic fragments at the inner bottom of the U-shaped lifting plate 9. A controller 16 is installed on the front side of the housing 1 to control the normal operation of the vibration motor 7 and the telescopic rod 8. The system also includes a dust removal mechanism, which consists of two screen plates 3 inclined above the fixed plate 2. The front and rear sides of the two screen plates 3 are in contact with the inner walls of the front and rear sides of the housing 1. Multiple connecting rods 4 are fixedly connected between the two screen plates 3. Each screen plate 3 is equipped with a screen 5. The screen aperture of the upper screen 5 is larger than that of the lower screen 5. The upper screen 5 can separate large agglomerated particles from the plastic granules and keep them at the top. The lower screen 5 can separate qualified particles from the plastic granules and keep them at the top. Finally, dust and small plastic fragments will pass through the two screens 5 and fall into the inner bottom of the U-shaped lifting plate 9. The lower end of the lower screen plate 3 is elastically connected to the upper end of the fixed plate 2 by multiple springs 6. A vibration motor 7 is installed at the lower end of the lower screen plate 3. With the help of the multiple springs 6, the two screen plates 3 and the screens 5 on them can be shaken to achieve the dust removal operation. The system also includes a lifting mechanism, which consists of a telescopic rod 8 installed at the bottom of the housing 1. The telescopic rod 8 is a hydraulic telescopic rod, and a U-shaped lifting plate 9 is fixedly connected to the telescopic end of the telescopic rod 8. The front and rear sides of the U-shaped lifting plate 9 are respectively attached to the inner walls of the front and rear sides of the housing 1. The vertical parts on both sides of the U-shaped lifting plate 9 penetrate the fixed plate 2 and are attached to the side walls of the two screen plates 3. The vertical parts on both sides of the U-shaped lifting plate 9 are provided with discharge channels 10. The discharge channel 10 on the left side is higher than the discharge channel 10 on the right side. After the U-shaped lifting plate 9 moves down, the discharge channel 10 on the left side can discharge the large granular agglomerates at the top of the upper screen 5, and the discharge channel 10 on the right side can discharge the qualified plastic granules at the top of the lower screen 5. Finally, these materials can be recycled through the discharge ports 14 on the left and right sides respectively. Two guide rods 12 are fixedly connected between the lower end of the fixed plate 2 and the bottom of the housing 1. Both guide rods 12 are slidably connected to the lower part of the U-shaped lifting plate 9.

[0015] In this invention, during use, the material to be removed is continuously poured into the entire device in small amounts from the feed inlet 13. After entering, the material first falls onto the upper end of the upper screen plate 3. At this time, the vibration motor 7 is started by the controller 16, which, together with multiple springs 6, drives the two screen plates 3 and the screens 5 on them to shake continuously. During the shaking process, the upper screen 5 can separate large particles and lumps from the material and keep them at the upper end, while the lower screen 5 separates qualified material from the material and keeps it at the upper end. The dust and small plastic fragments in the material pass through the two screens 5 and finally fall into the inner bottom of the U-shaped lifting plate 9 through the discharge channel 11 in the middle of the fixed plate 2. By continuing in this way, multi-stage removal of impurities from the material can be achieved efficiently, and the overall removal effect is good. After the impurities are removed, the telescopic rod 8 is controlled by the controller 16 to move the U-shaped lifting plate 9 down to the designated position. At this time, the large granular lumps at the top of the upper screen 5 can be discharged through the discharge channel 10 on the left side of the U-shaped lifting plate 9 and recycled through the discharge port 14 on the left side. The qualified plastic granules at the top of the lower screen 5 can be discharged through the discharge channel 10 on the right side of the U-shaped lifting plate 9 and recycled through the discharge port 14 on the right side. Finally, the pull door 15 on the front side of the housing 1 can be opened to recycle the dust and small plastic fragments at the bottom of the U-shaped lifting plate 9. The whole sorting and recycling process is relatively convenient and does not require manual sorting by staff, which reduces the workload of recycling and has good practicality. It is worth mentioning that when recycling materials, the vibration motor 7 can be started to drive the two screen plates 3 to shake, which in turn causes the material on them to shake, thereby improving the material discharge efficiency and thus improving the actual recycling efficiency. It should be noted that the wiring of the vibration motor 7, telescopic rod 8 and controller 16 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control, power supply method and wiring layout of the vibration motor 7, telescopic rod 8 and controller 16 will not be explained in detail.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
