Description

Technical Field

[0001] This invention relates to the field of mixing device technology, and specifically to a device for cleaning the surface of bolts after production and its usage method. Background Technology

[0002] Bolts are among the most commonly used components in mechanical connections. Their production process typically involves multiple steps, including forming, heat treatment, and machining. After these steps, the bolt surface inevitably accumulates deposits such as oxide scale, iron filings, oil, and dust. If these deposits are not removed promptly, they will not only affect the appearance of the bolt but also reduce its corrosion resistance and wear resistance, thereby impacting the connection strength and service life of the bolt. They may even lead to problems such as jamming or loosening during subsequent assembly, affecting the stability of the entire mechanical structure.

[0003] Currently, existing bolt surface cleaning equipment has the following shortcomings: First, the cleaning method is limited, mostly using a single spray or manual wiping, which is not thorough and makes it difficult to effectively remove stubborn deposits; second, the feeding and unloading process lacks orderly control, which can easily lead to bolt accumulation and conveying jams, resulting in uneven cleaning, and it is impossible to unload in batches, which is not conducive to subsequent packaging and transportation. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a bolt surface cleaning device and its usage method after production. It comprises a feeding and screening section, a high-pressure spray cleaning section, and a quantitative batch unloading section, sequentially connected along the material conveying direction. This achieves orderly feeding, thorough cleaning, and batch unloading of bolts, with smooth connections between each stage, significantly improving cleaning efficiency and quality. The high-pressure nozzles form an angle with the conveying surface of the inclined lifting section, allowing for all-around spraying of the bolt surface and effectively removing stubborn deposits. In the feeding and screening section, the feeding roller is a hollow cylindrical shape with screening holes, which can screen out fine impurities while pushing the bolts. The filter baffle achieves solid-liquid separation, reducing wear and tear on the equipment and secondary contamination of the bolts. The storage hopper is pull-out for easy filling and maintenance. The inclined design of the liquid collection tank facilitates waste liquid collection and discharge, making it more environmentally friendly. The high-pressure spray system uses a main pipeline and branch pipeline structure, ensuring even distribution of high-pressure nozzles and thorough cleaning of the bolts. The pre-wetting spray pipes pre-wet the bolts, improving cleaning efficiency and thoroughness.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bolt surface cleaning device after production, comprising;

[0006] The feeding and screening section, the high-pressure spray cleaning section, and the quantitative batch unloading section are connected sequentially along the material conveying direction;

[0007] The feeding and screening section includes a storage bin, and the storage bin is equipped with a feeding roller driven to rotate by a driving device.

The pushing blades are used to push the bolts from the bottom of the storage bin toward the high-pressure spray cleaning section.

[0008] The quantitative batch unloading section is located downstream of the feeding screening section and includes a chain plate conveying mechanism. The chain plate conveying mechanism includes an inclined lifting section and a horizontal transition section. The starting end of the inclined lifting section receives the bolts discharged from the storage bin. Several material distribution plates are equidistantly arranged on the conveying surface of the chain plate conveying mechanism along the conveying direction. A material loading trough for batch bearing bolts is formed between adjacent material distribution plates.

[0009] The high-pressure spray cleaning unit also includes a high-pressure spray system located above the inclined lifting section. The high-pressure spray system includes at least one row of high-pressure nozzles that spray cleaning medium toward the surface of the inclined lifting section. The high-pressure nozzles are connected to a high-pressure water pump through a water supply pipeline. The high-pressure water pump is connected to a water storage tank. The spray direction of the high-pressure nozzles forms an angle with the conveying surface of the inclined lifting section.

[0010] As a preferred embodiment of the present invention, the storage bin is installed on the frame in a pull-out manner, and a liquid collection tank is provided at the bottom of the storage bin. The bottom plate of the liquid collection tank is V-shaped with a high middle and low sides or is inclined to one side. A drain valve is provided at the lowest point of the liquid collection tank.

[0011] As a preferred embodiment of the present invention, the feeding roller has a hollow cylindrical structure, and a plurality of screening holes are provided on its cylindrical wall. The diameter of the screening holes is smaller than the minimum outer diameter of the bolt to be cleaned.

[0012] As a preferred embodiment of the present invention, the storage bin is provided with a filter partition with drainage holes, which divides the storage bin into an upper storage area and a lower drainage area. Roller supports are provided on the top of the two side walls of the storage bin, and the two ends of the feeding roller are supported on the roller supports by bearings.

[0013] As a preferred embodiment of the present invention, the high-pressure spraying system includes two parallel main pipelines and several branch pipelines. Each main pipeline extends along the width direction of the inclined lifting section, and the two ends of each branch pipeline are perpendicularly connected to the two main pipelines. Each branch pipeline is provided with multiple high-pressure nozzles at intervals along its length direction.

[0014] As a preferred embodiment of the present invention, the water supply pipeline is further branched into a pre-wetting spray pipe extending into the storage silo, and the outlet of the pre-wetting spray pipe faces the bolt.

[0015] As a preferred embodiment of the present invention, the chain conveyor mechanism includes a drive roller, a driven roller, a steering support roller, and a chain conveyor belt that is sleeved around the drive roller and the driven roller. The drive roller is located at the end of the horizontal transition section and is driven by a drive motor, and the driven roller is located at the bottom of the inclined lifting section.

[0016] As a preferred embodiment of the present invention, the steering support roller is located at the junction of the inclined lifting section and the horizontal transition section and is situated inside the chain conveyor belt to support the turning of the chain conveyor belt.

[0017] As a preferred embodiment of the present invention, the end of the quantitative batch unloading section is provided with a material collecting guide plate for receiving bolts that are conveyed in batches by the material separating plate.

[0018] The method of using a bolt surface cleaning device after production includes the following specific steps:

[0021] S3. High-pressure spraying: Start the high-pressure water pump to transport the cleaning medium in the water storage tank to the high-pressure spraying system through the water supply pipeline. The cleaning medium is then sprayed directionally onto the bolts on the inclined lifting section through the high-pressure nozzles. The spraying direction of the high-pressure nozzles is at an angle to the conveying surface of the inclined lifting section.

[0022] S4. The inclined lifting section of the chain plate conveyor lifts the cleaned bolts and transports them to the horizontal transition section. The material distribution plates set at intervals along the conveying direction on the conveying surface form a material loading trough. The bolts are carried in batches through the material loading trough and finally transported to the collection guide plate to complete the unloading.

In the feeding and screening section, the feeding roller is a hollow cylindrical shape with screening holes, which can screen out fine impurities while pushing the bolts. The filter baffle achieves solid-liquid separation, reducing wear and tear on the equipment and secondary contamination of the bolts. The storage hopper is pull-out for easy filling and maintenance. The inclined design of the liquid collection tank facilitates waste liquid collection and discharge, making it more environmentally friendly.

[0032] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0033] Example:

[0034] like Figure 1-7 As shown, this embodiment provides a bolt surface cleaning device after production, including a frame, on which a feeding screening section, a high-pressure spray cleaning section and a quantitative batch unloading section are sequentially connected along the material conveying direction.

[0035] The feeding and screening unit includes a storage bin 1, which is installed on the frame in a pull-out manner. Workers can add bolts to be cleaned by pulling the storage bin 1, which also facilitates cleaning and maintenance of the storage bin 1. The bottom of the storage bin 1 is provided with a liquid collection tank 12. The bottom plate of the liquid collection tank 12 is V-shaped with a high middle and low sides. The lowest point of the liquid collection tank 12 is provided with a drain valve 13, which can quickly collect and discharge the cleaning waste liquid for recycling.

[0036] The storage bin 1 is equipped with a filter baffle 14 with drainage holes 15. The filter baffle 14 divides the storage bin 1 into an upper storage area and a lower drainage area. Roller supports 16 are provided on the top of the two side walls of the storage bin 1. The roller supports 16 are supported by bearings on the roller supports 16. The roller supports 2 are driven to rotate by a drive device (drive motor 25 in this embodiment). The roller supports 2 have a hollow cylindrical structure. Several screening holes 17 are opened on the cylindrical wall. The diameter of the screening holes 17 is smaller than the minimum outer diameter of the bolt to be cleaned, which is used to screen out small impurities in the bolt. Several pushing blades 3 are arranged at equal intervals along the circumference on the surface of the roller supports 2. The pushing blades 3 are used to push the bolts in the storage bin 1 from the bottom of the storage bin 1 to the high-pressure spray cleaning section.

[0037] The quantitative batch unloading section is located downstream of the feeding and screening section and includes a chain plate conveyor mechanism. The chain plate conveyor mechanism includes a drive roller 21, a driven roller 22, a steering support roller 23, and a chain plate conveyor belt 24 that is sleeved around the drive roller 21 and the driven roller 22. The drive roller 21 is located at the end of the horizontal transition section 5 and is driven by a drive motor 25. The driven roller 22 is located at the bottom of the inclined lifting section 4. The steering support roller 23 is located at the junction of the inclined lifting section 4 and the horizontal transition section 5 and is located inside the chain plate conveyor belt 24 to support the smooth turning of the chain plate conveyor belt 24. Several material dividing plates 6 are equidistantly arranged on the conveying surface of the chain plate conveyor belt 24 along the conveying direction. A material loading trough 7 for batch bearing of bolts is formed between adjacent material dividing plates 6. The end of the quantitative batch unloading section is provided with a material collecting guide plate 26 for receiving the cleaned bolts conveyed in batches.

[0038] The high-pressure spray cleaning unit includes a high-pressure spray system located above the inclined lifting section 4. The system comprises two parallel main pipes 18 and several branch pipes 19. Each main pipe 18 extends along the width of the inclined lifting section 4. The two ends of each branch pipe 19 are perpendicularly connected to the two main pipes 18. Multiple high-pressure nozzles 8 are spaced apart along the length of each branch pipe 19. The high-pressure nozzles 8 are connected to a high-pressure water pump 10 via a water supply pipe 9. The high-pressure water pump 10 is connected to a water storage tank 11. The spray direction of the high-pressure nozzles 8 forms an angle of 30°-60° (45° in this embodiment) with the conveying surface of the inclined lifting section 4, ensuring comprehensive cleaning of the bolts. A pre-wetting spray pipe 20 extending into the storage silo 1 is also branched off from the water supply pipe 9. The outlet of the pre-wetting spray pipe 20 faces the bolts and is used for pre-wetting the bolts.

[0039] It should be noted that the drive device, high-pressure water pump 10, drive motor 25, etc. in this invention are all existing conventional equipment. Their specific models can be selected according to actual cleaning needs and equipment size. Their circuit connection method is existing conventional technology and will not be described in detail here. The cleaning medium can be selected according to the type of deposits on the bolt surface, such as clean water or neutral detergent solution, all of which are within the protection scope of this invention.

[0040] The method of using a bolt surface cleaning device after production includes the following specific steps:

[0041] S1. Feeding and preparing materials: Pull the storage bin 1 to put the bolts to be cleaned (bolts that have been formed and heat-treated, with oxide scale, iron filings, oil stains and other attachments on the surface) into the storage area of ​​the storage bin 1 and place them on the filter baffle 14 to complete the centralized storage of the bolts to be cleaned. Fine iron filings, dust and other impurities in the bolts fall into the drainage area and collection tank 12 below through the screening hole 17 of the feeding roller 2 and the drainage hole 15 of the filter baffle 14.

[0042] S2. Material feeding and conveying: Start the drive device (drive motor 25) to drive the feeding roller 2 in the storage bin 1 to rotate. The pushing blades 3 on the surface of the feeding roller 2 rotate synchronously with the feeding roller 2, and smoothly push the bolts in the storage bin 1 to the starting end of the inclined lifting section 4 of the chain plate conveyor mechanism. At the same time, open the control valve of the pre-wetting spray pipe 20, so that the cleaning medium in the water tank 11 (in this embodiment, it is clean water, and detergent can be added as needed) is transported to the pre-wetting spray pipe 20 through the branch of the water supply pipe 9, and spray the cleaning medium onto the bolts in the storage bin 1 to pre-wet and pre-dissolve the oil stains on the surface of the bolts.

[0043] S3. High-pressure spraying: Start the high-pressure water pump 10. The cleaning medium in the water storage tank 11 is transported to the main pipeline 18 of the high-pressure spraying system through the water supply pipeline 9, and then distributed to each high-pressure nozzle 8 through the branch pipeline 19. The high-pressure nozzle 8 sprays the high-pressure cleaning medium in a directional manner onto the bolts conveyed on the inclined lifting section 4. The spraying direction of the high-pressure nozzle 8 is at a 45° angle to the conveying surface of the inclined lifting section 4. The impact force of the high-pressure cleaning medium is used to thoroughly wash away the oxide scale, iron filings, oil stains and dust on the bolt surface, so as to achieve bolt surface cleaning. The waste liquid generated during the cleaning process drips through the gap of the chain conveyor belt 24 into the liquid collection tank 12 at the bottom of the storage bin 1 for centralized collection. The drain valve 13 is opened periodically to discharge the waste liquid for recycling.

[0044] S4. Unloading in batches: Start the drive motor 25 of the chain plate conveyor mechanism to drive the active roller 21 to rotate, which in turn drives the chain plate conveyor belt 24 to move. The inclined lifting section 4 slowly lifts and transports the cleaned bolts to the horizontal transition section 5. The turning support roller 23 supports and guides the chain plate conveyor belt 24 to ensure that the conveyor belt turns smoothly. The material distribution plate 6 on the chain plate conveyor belt 24 forms a material loading trough 7 to carry the cleaned bolts in batches to avoid bolt accumulation. Finally, the bolts are transported to the collection guide plate 26. The workers collect and package the cleaned bolts at the collection guide plate 26 to complete the entire cleaning operation.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
