Description

Technical Field

[0001] The utility model belongs to the field of regenerated plastic impurity removal, in particular to a pipe regenerated material impurity removal device. Background Art

[0002] At present, some excess waste is generated in the production process of plastic pipes, and plastic pipe products will also be recovered for reuse. The waste plastics recycled as recycled materials need to be crushed, cleaned and screened before subsequent processing can be carried out. Because debris, dust, etc. are inevitably mixed in during the process, it will affect the quality of subsequent processed products. Therefore, it is necessary to remove impurities from the plastic pipes first. The current impurity removal work is to remove the material from the water through a rotating structure during the cleaning process to complete the cleaning and impurity removal. However, this impurity removal method has a certain screening effect on stone dust, and is mainly for floating plastics. For plastic pipes, most of the plastic pipes are settled below. The cleaning mechanism similar to patent CN202211417266.7 will significantly reduce the cleaning effect of the precipitated plastic pipe recycled materials, and the removal effect of some floating impurities is very poor.

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-5 As shown:

[0029] A device for removing impurities from recycled pipe materials comprises a wind impurity removal mechanism 1 and a buoyancy impurity removal mechanism, wherein the wind impurity removal mechanism 1 comprises an impurity removal pipeline, the impurity removal pipeline is a vertically arranged serrated pipeline, the top of the impurity removal pipeline is arranged as an upper impurity discharge port 1-1, the impurity removal pipeline is provided with a feed port 1-2 below the impurity discharge port, the feed port 1-2 is connected to the impurity removal pipeline through a flange, an upper air inlet 1-3 is arranged below the feed port 1-2, the upper air inlet 1-3 is connected to the impurity removal pipeline through a flange, an annular pipe 1-4 is arranged at the bottom of the impurity removal pipeline, the annular pipe 1-4 is connected to the impurity removal pipeline through a flange, both ends of the annular pipe 1-4 are connected to the impurity removal pipeline, a lower air inlet 1-6 is arranged on a side wall of the impurity removal pipeline opposite to the lower end of the annular pipe 1-4, a lower impurity discharge port 1-5 is arranged on a side wall of the impurity removal pipeline opposite to the upper end of the annular pipe 1-4, and the lower air inlet 1-6 and the lower impurity discharge port 1-5 are both connected to the impurity removal pipeline through flanges;

[0030] A buoyancy impurity removal mechanism is arranged at the bottom of the wind impurity removal mechanism 1, and the buoyancy impurity removal mechanism comprises a water trough 2-1 and a spiral blade 2-2. The lower end of the impurity removal pipeline of the wind impurity removal mechanism 1 extends into the water trough 2-1. Side drainage troughs 2-3 are arranged on both sides of the water trough 2-1 below the wind impurity removal mechanism 1. The lower discharge port of the impurity removal pipeline is located at the side drainage trough 2-3. Spiral blades 2-2 are arranged inside the water trough 2-1. A lower drainage trough 2-7 and an upper drainage trough 2-6 are arranged at one end of the water trough 2-1 away from the wind impurity removal mechanism 1. The feeding direction of the spiral blade 2-2 is the direction of the lower drainage trough 2-7.

[0031] The feed port 1-2 is arranged at the first tooth shape close to the upper impurity discharge port 1-1, and the upper air inlet 1-3 is arranged at the adjacent tooth shape on the same side of the feed port 1-2. Fans are arranged at the feed port 1-2 and the upper air inlet 1-3. After the material is input from the feed port 1-2, it is continuously collided and separated at the serrated pipe, and then the wind force removes light impurities from the scattered material, and the impurities are discharged from the upper impurity discharge port 1-1 with the wind force, and the recycled material will continue to move downward due to gravity.

[0032] The end of the impurity removal pipe of the wind impurity removal mechanism 1 where the material outlet is located is a straight pipe, the straight pipe of the impurity removal pipe is connected to the annular pipe 1-4, the lower air inlet 1-6 is provided with a fan, and the lower impurity discharge port 1-5 is connected to the impurity removal pipe of the impurity removal mechanism. The regenerated material will disperse and fall at the straight pipe, and the wind from the lower air inlet 1-6 will blow the light impurities that are not completely removed to the lower impurity discharge port 1-5 through the annular pipe 1-4, and the wind will also promote the dispersion of the regenerated material to better remove impurities.

[0033] The bottom of the water tank 2-1 is arc-shaped, and the arc radius of the bottom of the water tank 2-1 is the same as the radius of the spiral blade 2-2, so as to facilitate the feeding of recycled materials and avoid the leakage of recycled materials.

[0034] The side wall of the discharge port at the bottom of the impurity removal pipeline of the wind impurity removal mechanism 1 is provided with an air duct baffle 2-5, and the two sides of the air duct baffle 2-5 are connected to the impurity removal pipeline through a slideway, and a handle is provided on the air duct baffle 2-5. Three air duct baffles 2-5 are provided, two facing the side wall of the water tank 2-1, and the third facing the lower drainage trough 2-7. The discharge direction of the floating material can be controlled by controlling the switches of the three air duct baffles 2-5. The impurity removal pipeline has the same width as the water tank 2-1, so that the regenerated material can be controlled to be discharged from the side drainage trough 2-3 through the air duct baffles 2-5 on both sides, or the air duct baffles 2-5 on both sides are blocked, and the air duct baffles 2-5 facing the lower drainage trough 2-7 are opened, so that the floating material is discharged from the upper drainage trough 2-6.

[0035] The bottoms of the upper drainage groove 2-6, the lower drainage groove 2-7 and the side drainage groove 2-3 are all provided with water leakage holes, which can accelerate the water discharge, thereby accelerating the separation of the discharge and the water.

[0036] The water tank 2-1 is provided with a water tank baffle 2-4 at the connection of the upper drainage tank 2-6, the two sides of the water tank baffle 2-4 are connected to the water tank 2-1 through slideways, the water tank baffle 2-4 is provided with a handle, and the water tank 2-1 is provided with a rotating baffle 2-8 at the entrance of the lower drainage tank 2-7, the rotating baffle 2-8 is connected to the water tank 2-1 through a bearing, and the rotating baffle 2-8 is fan-shaped. The discharge of materials can be controlled by the water tank baffle 2-4 and the rotating baffle 2-8.

[0037] A wastewater recovery tank is arranged below the water tank 2-1 to recycle wastewater and reduce waste of resources.

[0038] How this example works:

[0039] During use, the pipe recycled material that needs to be cleaned and cleaned is fed in from the feed port 1-2, and moves downward from the impurity removal pipe of the wind impurity removal mechanism 1 with the wind force of the fan. The zigzag shape of the impurity removal pipe causes the material to collide and disperse continuously, so that the air can flow better, and take away the light impurities in the material from the gaps, and discharge them from the upper impurity discharge port 1-1 above with the wind force. The wind force of the feed port 1-2 prevents the impurities from being discharged from the feed port 1-2. When the material reaches the straight pipe part below the impurity removal pipe, it is relatively dispersed due to collision, and is blown away for the second time by the wind force of the lower air inlet 1-6 and the annular pipe 1-4, so that the light impurities in the material are discharged from the lower impurity discharge port 1-5 by the wind force. The lower impurity discharge port 1-5 is provided with a grille to prevent the material from being blown out by the wind, and the grille is in the shape of an inclined louver.

[0040] After the material enters the buoyancy impurity removal mechanism from the wind impurity removal mechanism 1, it falls directly into the water. After multiple dispersions, the recycled material falls into the water and the sedimentation material and floating impurities are immediately separated. The material is continuously stirred forward by the feeding effect of the spiral blade 2-2, thereby completing the cleaning work. The floating impurities can be quickly discharged by closing the air duct baffle 2-5 facing the lower drainage trough 2-7 and opening the air duct baffle 2-5 facing the side drainage trough 2-3, or by opening the air duct baffle 2-5 facing the drainage trough 2-1, the floating impurities are discharged from the upper drainage trough 2-6. The water trough baffle 2-4 can control the discharge time and discharge size, and the size of the discharge time can also be controlled by rotating the baffle 2-8.

[0041] In the second embodiment, when the water tank 2-1 is used to clean and separate floating materials and precipitated impurities, the air duct baffle 2-5 toward the lower drainage tank 2-7 is opened, and the air duct baffles 2-5 toward both sides of the water tank 2-1 are closed, so that the floating materials are cleaned during the movement, and the precipitated impurities are fed and discharged through the spiral blades 2-2, thereby completing the cleaning and impurity removal of the floating materials.

[0042] The secondary impurity removal and cleaning by wind power and buoyancy can better remove light impurities than the existing impurity removal devices, and can remove floating impurities of different densities while completing the cleaning work, with higher work efficiency and better impurity removal effect.
