Description

Technical Field

[0001] This utility model relates to a screening device for bisphenol A recovery materials, belonging to the technical field of material screening equipment. Background Technology

[0002] Bisphenol A (BPA) recovery material screening equipment is used to screen recovered BPA materials, removing impurities and substandard particles to obtain BPA recovery material that meets quality requirements. Its working principle is typically based on differences in the physical properties of the materials, such as particle size and density, to achieve screening.

[0003] A system and method for collecting, conveying, and screening bisphenol A (BPA) material, Chinese patent number CN117509035A, is disclosed. The system includes a collection system, a conveying system, and a screening system. The collection system includes a collection drive assembly, a scraper arm, a scraper plate, and a distance detection assembly. The screening system is connected to the end of the conveying system via a flexible connection. The conveying system transports the material swept into the conveying system from the collection system to the screening system. The screening system separates unqualified BPA material by using a rotary reciprocating motion at the inlet and a linear motion at the outlet.

[0004] When bisphenol A (BPA) reclaimed material accumulates in the middle of the screen, the material thickness in the middle is much greater than at the edges. This concentrated accumulation in the middle causes significantly higher pressure compared to other areas. During vibratory screening, this uneven pressure distribution exacerbates wear in the middle of the screen, shortening the equipment's lifespan and increasing maintenance costs and replacement frequency.

[0005] Therefore, a screening device for bisphenol A recovery materials is proposed. Utility Model Content

[0006] In view of this, the present invention provides a screening device for bisphenol A recycled materials to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A bisphenol A recovery material screening device includes a device base, a material storage top frame is provided on the upper front side of the device base, a material discharge opening bin is fixedly connected to the lower end of the material storage top frame, a transverse rotating shaft is rotatably connected between the left and right inner walls of the material discharge opening bin, a plurality of rubber arc-shaped material discharge rotating plates are fixedly connected to the outer end of the transverse rotating shaft, the plurality of rubber arc-shaped material discharge rotating plates are arranged in a ring at equal intervals, a plurality of channel partition uniform plates are fixedly connected to the lower end of the material discharge opening bin, the plurality of channel partition uniform plates are arranged at equal intervals from left to right, a screening groove plate is provided on the upper end of the device base, and an inclined screen plate is fixedly connected to the middle of the inner end of the screening groove plate.

[0008] More preferably, multiple partition plates are evenly distributed above the inclined screen plate, and a drive motor is installed at the left end of the discharge opening.

[0009] More preferably, the output end of the drive motor extends into the unloading opening, and the output end of the drive motor is connected to the transverse rotating shaft.

[0010] More preferably, discharge arc plates are fixedly connected to the left and rear sides of the screening groove plate, and the two discharge arc plates are located at the upper and lower ends of the inclined screen plate, respectively.

[0011] More preferably, a pair of vibrators are fixedly connected to one end of the rubber arc-shaped feeding plate away from the transverse rotating shaft, and the output ends of the corresponding two vibrators are fixedly connected to a tamping auxiliary crossbar.

[0012] More preferably, the outer walls of the rubber arc-shaped feeding plate and the tamping auxiliary crossbar are both fixedly connected with a wear-resistant coating, and the inner end of the storage top frame is filled with a number of bisphenol A granules.

[0013] More preferably, the bisphenol A recycled material runs through the inside and outside of the feeding opening hopper, and extends to the position above the inclined screen plate.

[0014] More preferably, inclined guide plates are symmetrically fixedly connected to the left and right ends of the storage top frame, and the two inclined guide plates are respectively located above the material discharge opening.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] 1. In this solution, during the feeding process of bisphenol A (BPA) recycled material in the top frame of the storage compartment, multiple rubber arc-shaped feeding plates on its outer side can be driven to rotate at a uniform speed through the transverse rotating shaft, conveying the BPA recycled material over a large area to the inclined screen plate. At the same time, the BPA recycled material is placed in the intervals of the dividing plate at the corresponding position. When the BPA recycled material is evenly distributed on the inclined screen plate instead of being concentrated in the middle, the evenly distributed material makes the pressure on each part of the screen uniform, avoiding excessive wear in the middle, extending the service life of the inclined screen plate, and avoiding accumulation in the middle can reduce the number of repeated screenings, further improving the overall screening efficiency.

[0017] Second, the end of the rubber arc-shaped feeding plate can also be equipped with a tamping auxiliary crossbar driven by a vibrator. The tamping auxiliary crossbar can provide vibration force to disperse the tightly piled material in the top frame of the storage, making the feeding process more evenly distributed. In addition, the inner walls of the two inclined guide plates below the top frame of the storage are made of smooth stainless steel to ensure that the bisphenol A recycled material can fall smoothly to the feeding opening hopper for screening by gravity.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model embodiment provides a bisphenol A recovery material screening device, including a device base 1, a material storage top frame 5 is provided on the upper front side of the device base 1, a material discharge opening hopper 6 is fixedly connected to the lower end of the material storage top frame 5, a transverse rotating shaft 9 is rotatably connected between the left and right inner walls of the material discharge opening hopper 6, a plurality of rubber arc-shaped material discharge rotating plates 10 are fixedly connected to the outer end of the transverse rotating shaft 9, the plurality of rubber arc-shaped material discharge rotating plates 10 are arranged in a ring at equal intervals, a plurality of channel partition uniform plates 11 are fixedly connected to the lower end of the material discharge opening hopper 6, the plurality of channel partition uniform plates 11 are arranged at equal intervals from left to right, a screening groove disk 2 is provided on the upper end of the device base 1, and an inclined screen mesh plate 3 is fixedly connected to the middle of the inner end of the screening groove disk 2.

[0030] Multiple partition plates 11 are evenly distributed above the inclined screen plate 3. A drive motor 8 is installed at the left end of the discharge opening hopper 6. The output end of the drive motor 8 extends into the discharge opening hopper 6 and is connected to the transverse rotating shaft 9. Discharge arc plates 4 are fixedly connected to the left and rear sides of the screening groove plate 2. The two discharge arc plates 4 are located at the upper and lower ends of the inclined screen plate 3, respectively. The inner end of the storage top frame 5 is filled with a number of bisphenol A particles. The bisphenol A recycled material runs through the inside and outside of the discharge opening hopper 6 and extends to the position above the inclined screen plate 3.

[0031] Example 2

[0032] like Figure 2-5 As shown, in one embodiment, a pair of vibrators 12 are fixedly connected to one end of the rubber arc-shaped feeding plate 10 away from the transverse rotating shaft 9. The output ends of the two corresponding vibrators 12 are fixedly connected to the tamping auxiliary crossbars 13. The outer walls of the rubber arc-shaped feeding plate 10 and the tamping auxiliary crossbars 13 are both fixedly connected to wear-resistant coatings 14. The left and right ends of the storage top frame 5 are symmetrically fixedly connected to inclined guide plates 7. The two inclined guide plates 7 are respectively located above the feeding opening hopper 6.

[0033] The end of the rubber arc-shaped feeding plate 10 can also be equipped with a tamping auxiliary crossbar 13 driven by a vibrator 12. The tamping auxiliary crossbar 13 can provide vibration force to disperse the tightly packed material in the top storage frame 5, making the feeding process more evenly distributed. The inner walls of the two inclined guide plates 7 below the top storage frame 5 are made of smooth stainless steel to ensure that the bisphenol A recycled material can slide smoothly to the feeding opening hopper 6 for screening operations by gravity.

[0034] In operation, this invention works as follows: Bisphenol A (BPA) recycled material is stored in the top storage frame 5 and conveyed to the screening groove plate 2 via the discharge opening hopper 6. This causes the BPA recycled material to bounce and move forward on the inclined screen plate 3. Larger particles of BPA recycled material with a diameter greater than the aperture of the inclined screen plate 3 are retained on the inclined screen plate 3 and conveyed to the corresponding discharge arc plate 4 with vibration. Material with a diameter smaller than the BPA recycled material passes through the bottom of the inclined screen plate 3, allowing for the separation and screening of BPA recycled material with different particle sizes. The inclined screen plate 3 is precisely controlled by a driver and frequency converter to ensure uniform and stable feeding. Simultaneously, during the discharge of BPA recycled material from the top storage frame 5, multiple rubber arc-shaped discharge plates 10 on its outer side can be driven to rotate at a uniform speed via the transverse rotating shaft 9, conveying a large area of ​​BPA recycled material to the inclined screen plate 3. Bisphenol A (BPA) recycled material is positioned in the intervals of the dividing plate 11 at the corresponding locations. When the BPA recycled material is evenly distributed on the inclined screen plate 3 instead of being concentrated in the middle, the evenly distributed material ensures that the pressure on each part of the screen is uniform, avoiding excessive wear in the middle and extending the service life of the inclined screen plate 3. Avoiding concentration in the middle can reduce the number of repeated screenings and further improve the overall screening efficiency. At the same time, the end of the rubber arc-shaped feeding plate 10 can also be equipped with a tamping auxiliary crossbar 13 driven by a vibrator 12. The tamping auxiliary crossbar 13 can provide vibration force to disperse the tightly packed material in the storage top frame 5, making the feeding process more evenly distributed. In addition, the inner walls of the two inclined guide plates 7 below the storage top frame 5 are made of smooth stainless steel to ensure that the BPA recycled material can smoothly slide down to the feeding opening hopper 6 by gravity for screening.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
