[0001] This utility model relates to brass fasteners, and in particular to a drying device for the production of brass fasteners. Background Technology

[0002] Brass fasteners have good mechanical properties, can withstand certain tensile, compressive and shear forces, meet the fastening needs under different working conditions, and have good corrosion resistance. Therefore, they are widely used in many fields such as machinery, construction, and electrical appliances.

[0003] After passivation, electroplating and other operations, brass fasteners need to be cleaned and dried. During the drying process, the waste liquid remaining on the surface of the brass fasteners will drip into the drying equipment. After long-term use, the bottom of the drying equipment is easily corroded by the waste liquid, which will lead to damage to the drying equipment. To address this, many existing drying equipment are equipped with a drain tank at the bottom.

[0004] However, fine solid impurities may still remain on the surface of brass fasteners after cleaning. These solid impurities drip down to the bottom of the drying equipment with the waste liquid, and after the waste liquid is discharged through the drain tank, these solid impurities will remain at the bottom of the drying equipment, corroding the drying equipment and causing damage to it.

[0005] To address the above issues, we propose a drying device for the production of brass fasteners. Utility Model Content

[0012] A further feature of this invention is that a cone is fixedly connected to the bottom wall of the drying chamber, and the output shaft of the second motor is rotatably connected to the cone.

[0013] The output shaft of the second motor is fixedly connected to a conical top, the base area of ​​which is larger than the base area of ​​the frustum.

[0014] A further feature of this invention is that the waste liquid collection mechanism includes a placement frame installed on the lower side of the drying cylinder, a liquid storage tank is placed inside the placement frame, and the liquid storage tank has an upward-facing liquid storage cavity.

[0015] A platform is integrally formed on the side wall of the liquid storage chamber, and a filter screen is abutted on the platform.

[0016] A further feature of this invention is that a sealing ring is provided at the connection between the upper side of the liquid storage chamber and the lower outer edge of the drain trough.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example:

[0030] like Figures 1 to 4As shown, a drying device for brass fastener production includes a drying cylinder 11, the outer surface of which is provided with a heat insulation layer to prevent the outer surface of the drying cylinder 11 from overheating and causing burns to technicians. An insulation door 29 is provided on the circumferential side wall of the drying cylinder 11. A drying chamber 12 is formed inside the drying cylinder 11, and several infrared lamp plates 27 for drying brass fasteners are installed on the circumferential side wall of the drying chamber 12. A rotating shaft 13 is rotatably connected to the top wall of the drying chamber 12. A primary motor 14 is installed on the shaft 13 to drive it. Several drying racks 15 are provided on the circumferential side wall of the shaft 13. Several placement holes 28 are opened vertically through each drying rack 15. Before the drying operation begins, the technicians vertically insert the brass fasteners to be dried into each of the placement holes 28 and close the door. Then, the primary motor 14 drives the shaft 13 to rotate, so that the brass fasteners placed on the drying rack 15 can be evenly dried by the infrared lamp plate 27.

[0031] A drain trough 16 is provided through the bottom wall of the drying chamber 12. A placement rack 21 is installed on the lower side of the drying cylinder 11. A storage tank 22 is placed in the placement rack 21. The storage tank 22 has an upward-facing storage cavity 23. Waste liquid remaining on the surface of the brass fastener drips to the bottom of the drying chamber 12 and is discharged into the storage cavity 23 through the drain trough 16 to prevent the waste liquid from accumulating at the bottom of the drying chamber 12 and corroding the bottom wall of the drying chamber 12. A sealing ring 26 is provided at the connection between the upper side of the storage cavity 23 and the lower outer edge of the drain trough 16 to prevent the waste liquid from leaking through the connection between the storage cavity 23 and the drain trough 16 and polluting the production environment.

[0032] A second motor 18 is installed on the lower side of the drying cylinder 11. The output shaft of the second motor 18 extends into the drying chamber 12, and a cleaning brush 17 is fixedly connected to the output shaft of the second motor 18. The bristles of the cleaning brush 17 abut against the bottom wall of the drying chamber 12. After the brass fasteners are dried, the second motor 18 drives the cleaning brush 17 to perform a circular motion at the bottom of the drying chamber 12. During this process, the small solid impurities remaining on the bottom wall of the drying chamber 12 are swept into the drain trough 16 by the cleaning brush 17 to ensure the bottom of the drying chamber 12 is clean and to prevent the small solid impurities from corroding the bottom wall of the drying chamber 12.

[0033] Furthermore, in order to separate the fine solid impurities from the waste liquid for recycling by technicians, a platform 24 is integrally formed on the side wall of the liquid storage chamber 23. A filter screen 25 is attached to the platform 24. After the fine solid impurities enter the liquid storage chamber 23, they will be blocked on the filter screen 25, thereby achieving solid-liquid separation. After the technicians remove the liquid storage tank 22, they will remove the filter screen 25, clean the fine solid impurities attached to the surface of the filter screen 25, and recycle it for reuse.

[0034] In addition, a truncated cone 19 is fixedly connected to the bottom wall of the drying chamber 12. The output shaft of the second motor 18 is rotatably connected to the truncated cone 19. A conical top 20 is fixedly connected to the end of the output shaft of the second motor 18. The truncated cone 19 can prevent the waste liquid and the solid particulate impurities from accumulating in the cleaning blind area of ​​the cleaning brush 17. The conical top 20 can prevent the waste liquid from accumulating on the upper side of the output shaft of the second motor 18 and causing corrosion. Moreover, the bottom area of ​​the conical top 20 is larger than the bottom area of ​​the truncated cone 19, thereby ensuring that the waste liquid dripping onto the conical top 20 will not stay on the upper side of the truncated cone 19, but will flow downward and collect at the bottom of the drying chamber 12, and finally fall into the liquid storage chamber 23 through the cleaning of the cleaning brush 17.

[0035] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
