Description

Technical Field

[0001] This utility model relates to the field of mechanical processing waste recycling technology, specifically to a valve plate processing waste sorting and recycling device. Background Technology

[0002] During machining processes, cutting, milling, drilling, and other operations on workpieces such as valve plates generate a large amount of metal shavings, plastic scraps, or other waste. Traditional waste recycling methods mainly rely on manual sorting or simple screening, which has the following problems:

[0003] Low sorting efficiency: Waste materials are usually mixed and piled up, and it is difficult to quickly separate fragments of different particle sizes, which affects subsequent recycling.

[0004] Incomplete recycling: Small waste materials are easy to remain, manual cleaning is time-consuming and labor-intensive, and may cause dust pollution.

[0005] Poor equipment flexibility: Existing sorting devices mostly use fixed screens or single-direction air sweeping, which are difficult to adapt to the recycling needs of different waste materials and are inconvenient to adjust.

[0006] To address the aforementioned problems, some existing waste sorting devices employ multi-layer screens or airflow-assisted separation, but these still have the following shortcomings:

[0007] The screen is prone to clogging, making cleaning and maintenance inconvenient;

[0008] The airflow direction is fixed, and the blowing angle cannot be flexibly adjusted, resulting in uneven waste sorting;

[0009] The waste collection and airflow circulation system has low integration and high energy consumption.

[0010] Therefore, there is an urgent need for a waste recycling device with a reasonable structure, high sorting efficiency, and convenient operation to improve the waste recycling rate and reduce manual intervention. Utility Model Content

[0011] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a valve plate processing waste sorting and recycling device, which can effectively solve the problems mentioned in the background technology.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] This utility model provides a valve plate processing waste sorting and recycling device, including a recycling box. The top of the recycling box has a recycling cavity. Several horizontally placed filter screens adapted to the cross-sectional specifications of the recycling cavity are detachably installed in the recycling cavity. The mesh size of the filter screens gradually decreases from top to bottom. A fan is installed at the bottom of the recycling box. The input end of the fan is connected to the bottom of the recycling cavity. The output end of the fan is connected to a blower pipe fixedly installed on the outer wall of the recycling box. The end of the blower pipe away from the fan is located at the upper cavity opening of the recycling cavity and is rotatably installed with a corrugated pipe.

[0014] Furthermore, the four inner walls of the recycling chamber are provided with three parallel inner grooves, and the outer wall of the recycling box is provided with three strip grooves, which are respectively connected to the corresponding inner grooves.

[0015] Furthermore, two support seats are vertically fixedly installed at the bottom of the recycling bin. The two support seats are centrally symmetrical about the fan, and the bottom height of the two support seats is lower than the bottom height of the fan.

[0016] Furthermore, storage frames are respectively inserted into the three inner grooves in a corresponding manner, and the top of each of the three storage frames has a square cavity extending through the bottom. The three filters are respectively embedded and fixedly installed in the bottom of the square cavity.

[0017] Furthermore, each of the three storage frames has a baffle fixedly installed on the same side, and the three baffles are respectively inserted into the corresponding strip grooves. Each of the three baffles has a handle fixedly installed vertically on the side away from the corresponding storage frame.

[0018] Furthermore, two suction pipes are connected between the input end of the blower and the bottom of the recovery chamber. An annular limiting groove is provided on the inner wall of the blowing pipe near the corrugated pipe end. An annular limiting ring is fixedly fitted on the outer wall of the corrugated pipe inserted into the inner cavity of the blowing pipe. The annular limiting ring is rotatably installed in the annular limiting groove.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] Highly efficient graded recycling: Multi-layer filter screens enable automatic stratified collection of waste materials according to particle size, improving sorting accuracy and recovery rate.

[0021] Airflow recycling: The fan forms a closed air path, and the airflow is drawn from bottom to top and blown from top to bottom in a cycle, which promotes the full suspension and multiple filtration of lightweight waste materials (such as plastic shavings) to reduce residue.

[0022] Flexible adjustment of blowing direction: The corrugated pipe structure allows the blowing pipe to be adjusted at any angle, enabling directional blowing of accumulated waste materials and improving sorting efficiency.

[0023] Easy maintenance: The pull-out filter design makes it easy to clean clogged mesh and reduces downtime.

[0024] Energy saving and environmental protection: The circulating airflow system reduces energy consumption, and the closed recovery chamber suppresses dust overflow and improves the working environment. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example 1:

[0038] Reference Figure 1-5 This is the first embodiment of the present invention, disclosing a valve plate processing waste sorting and recycling device. Its features include a recycling box 1, with a recycling chamber 11 at the top. Several horizontally placed filter screens 24, adapted to the cross-sectional dimensions of the recycling chamber 11, are detachably installed within the recycling chamber 11. The filter screens 24 are grounded, and the mesh size of the filter screens 24 gradually decreases from top to bottom (upper layer mesh diameter 5-8mm, middle layer 3-5mm, lower layer 1-3mm). A fan 31 (power 0.75-1.5kW, air volume 800-1200m³ / h) is installed at the bottom. The input end of the fan 31 is connected to the bottom of the recovery chamber 11. The output end of the fan 31 is connected to a blower pipe 33 (diameter 80-100mm) that is fixedly installed on the outer wall of the recovery box 1. The end of the blower pipe 33 away from the fan 31 is set at the upper cavity opening of the recovery chamber 11, and a corrugated pipe 34 (length 300-500mm, bendable angle 0-90°) is rotatably installed thereon.

[0039] Example 2:

[0040] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0041] The four inner walls of the recycling chamber 11 are provided with three parallel grooves 12 (groove depth 15-20mm, groove width 20-25mm). The outer wall of the recycling box 1 is provided with three strip grooves 13 (length 200-250mm, width 25-30mm). The three strip grooves 13 are connected to the corresponding inner grooves 12. The bottom of the recycling box 1 is vertically fixed with two support seats 14 (height 100-150mm, material Q235 steel). The two support seats 14 are symmetrically distributed about the fan 31, and the bottom height of the two support seats 14 is lower than the bottom height of the fan 31 (50-80mm lower). The three inner grooves 12 are respectively fitted with storage frames 21 (material 304 stainless steel, wall thickness 1.5-2mm). The top of each of the three storage frames 21 is provided with a square cavity (size 400×400mm) extending through the bottom. The three filters 24 are respectively fitted and fixedly installed in the bottom of the square cavity.

[0042] Each of the three storage boxes 21 has a baffle 22 (180-200mm in length, 5-8mm in thickness) fixedly installed on one side facing the same direction. The three baffles 22 are respectively inserted into the corresponding strip grooves 13. Each of the three baffles 22 has a handle 23 (30-40mm in diameter, made of ABS plastic) fixedly installed vertically on the side away from the corresponding storage box 21. There are two suction pipes 32 (60-80mm in diameter) connecting the input end of the blower 31 and the bottom of the recovery chamber 11. The inner wall of the blower pipe 33 near the corrugated pipe 34 has an annular limiting groove 35 (3-5mm deep, 8-10mm wide). The corrugated pipe 34 is inserted into the inner cavity of the blower pipe 33 and an annular limiting ring 36 (4-6mm thick) is fixedly fitted on the outer wall. The annular limiting ring 36 is rotatably installed in the annular limiting groove 35.

[0043] The remaining structure is the same as that in Example 1.

[0044] (Supplementary notes: The overall dimensions of recycling bin 1 are 800×800×1200mm, and it is made of 1.2mm thick galvanized steel plate; the filter screen 24 is made of 304 stainless steel woven mesh with a wire diameter of 0.5-0.8mm; a rubber shock-absorbing pad with a thickness of 10-15mm is installed between the blower 31 and recycling bin 1; the corrugated pipe 34 is made of 304 stainless steel with a corrugation spacing of 15-20mm).

[0045] The remaining structure is the same as that in Example 1.

[0046] This utility model's valve plate processing waste sorting and recycling device achieves efficient sorting and recycling of waste materials of different particle sizes through the synergistic effect of a multi-layer filter screen with 24-level grading and an adjustable airflow circulation system. Its specific working process is as follows:

[0047] 1. Waste material input and preliminary screening

[0048] Waste disposal: Mixed waste generated during processing, such as metal shavings and plastic scraps, is disposed of through the top opening of the recycling chamber 11.

[0049] Step-by-step filtration: Waste first falls onto the top layer of filter screen 24. This layer has larger mesh, allowing only smaller particles of waste to pass through, while larger particles such as metal blocks and coarse plastic sheets are trapped in this layer.

[0050] Continuing to fall: The waste passing through the upper filter screen 24 continues to fall to the middle filter screen 24. This layer has smaller mesh size, which further screens medium-sized waste particles. The remaining fine particles finally fall to the bottom filter screen 24 with the smallest mesh size, thus achieving three-level classification of waste.

[0051] 2. Airflow circulation and fine sorting

[0052] Fan start-up: After the fan 31 is started, its input end draws air from the bottom of the recovery chamber 11 through the air extraction pipe 32 to form a negative pressure.

[0053] Airflow circulation path:

[0054] The air that is drawn in is pressurized by the fan 31 and then transported to the top of the recovery chamber 11 through the blower pipe 33.

[0055] Airflow is blown out from the outlet of bellows 34, and the direction is adjustable, so that the waste material forms a dynamic suspension state in the cavity.

[0056] The function of secondary sorting:

[0057] Lighter waste materials, such as plastic sheets and fine metal shavings, are re-lifted by the airflow and pass through the various filter screens 24 again to ensure thorough screening.

[0058] Heavier waste continues to fall due to gravity and is eventually intercepted by the corresponding filter screen 24.

[0059] 3. Adjustment of the blower tube angle

[0060] The corrugated pipe 34 can be adjusted flexibly: the operator can manually bend the corrugated pipe 34 according to the waste accumulation, change the air outlet direction, and make the airflow accurately blow to the area with dense waste, thereby improving the sorting efficiency.

[0061] Rotational limiting structure: The bellows 34 is matched with the annular limiting groove 35 of the blower pipe 33 through the annular limiting ring 36 to ensure that it can be rotated and adjusted 360°, while preventing it from falling off.

[0062] 4. Waste collection and disposal

[0063] Storage Box 21:

[0064] Each filter 24 is embedded in a pull-out storage frame 21, which is fixed by a baffle 22 and a strip groove 13.

[0065] When a certain amount of waste accumulates in a certain layer, the operator can periodically pull the handle 23 outward to remove the collection box 21 from the recycling chamber 11 and pour out the waste.

[0066] Quick reset: After cleaning, push the storage box 21 back to its original position along the strip groove 13, and the stop bar 22 ensures that it is accurately positioned before continuing to work.

[0067] 5. System stability and maintenance

[0068] Fan vibration reduction design: The support base 14 at the bottom of the recycling box 1 is lower than the bottom surface of the fan 31, so that the fan can run in the air, reducing vibration transmission and noise.

[0069] Anti-clogging optimization:

[0070] The multi-layer filter structure reduces the load on a single layer and lowers the risk of clogging.

[0071] Airflow circulation promotes the even distribution of waste materials and avoids local accumulation.

[0072] 6. Workflow Summary

[0073] 1. Feeding → 2. Multi-layer screening → 3. Airflow-assisted suspension and secondary sorting → 4. Adjusting the airflow direction to optimize sorting → 5. Regularly cleaning the storage box → 6. Cyclic operation.

[0074] This invention significantly improves the sorting accuracy and recycling efficiency of waste materials by combining mechanical screening with airflow assistance. It also has advantages such as flexible operation, convenient maintenance, energy saving and environmental protection, and is suitable for the recycling and processing of various types of mechanical processing waste materials.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
