[0002] Stainless steel pipes are widely used in various industrial fields such as petroleum, chemical, pharmaceutical, food, construction, etc. due to their excellent corrosion resistance, high strength and aesthetics. In these fields, the quality and cleanliness of stainless steel pipes are crucial to ensure smooth process flow and product quality.
[0003] However, during the production, processing and transportation, various oils, greases and other impurities often adhere to the surface of stainless steel pipes. These oils and impurities not only affect the appearance quality of the pipes, but may also affect their corrosion resistance and shorten their service life; therefore, it is necessary to degrease the stainless steel pipes; for workshops that use pickling and degreasing methods for production, the presence of pickling tanks will lead to a poor production environment and poor air quality, which will have an adverse effect on the health of workers who pickle and load stainless steel pipes for a long time, and the efficiency of manual loading and unloading is also very low; there are also operations that use gantry cranes for lifting and unloading, but special pickling hoists are required, and manual packaging is still required; for this reason, we provide a stainless steel pipe pickling and degreasing equipment. Utility Model Content
[0004] The utility model aims to provide a stainless steel pipe pickling and degreasing device.
[0005] The technical problems solved by the utility model are:
[0006] (1) How to automatically load and unload stainless steel pipes and automatically pickle them without manual intervention;
[0007] (2) How to adapt to the pickling operation of stainless steel pipes with different lengths and diameters within a certain range;
[0008] The utility model can be realized by the following technical scheme: the stainless steel pipe pickling and degreasing equipment comprises a pickling tank, an automatic material trough is arranged on the top of the pickling tank, a circular empty slot is opened in the middle of the automatic material trough, a material dividing roller which can divide and transport the stainless steel pipe is rotatably arranged in the circular empty slot, and a channel for only one stainless steel pipe to pass through is arranged directly above and directly below the material dividing roller;
[0009] A drive roller is provided in the pickling tank for horizontal rotation. Two bearing turntables for carrying and transporting stainless steel pipes are symmetrically installed on the drive roller through splines. An arc-shaped support component is also provided on the outer side of each bearing turntable, and the support component is slidably connected to the pickling tank.
[0010] The further technical improvement of the utility model is that a driven wheel is coaxially fixed on one side of the material distribution roller, a driving wheel is fixedly installed on one end of the transmission roller, a synchronous transmission belt is arranged between the driving wheel and the driven wheel, and synchronous transmission is performed through the synchronous transmission belt.
[0011] The further technical improvement of the utility model is that: a plurality of limit racks are evenly installed on the material distribution roller, and the distance between two adjacent limit racks matches the diameter of the stainless steel pipe.
[0012] The further technical improvement of the utility model is that the bearing turntable includes a turntable body and a mounting sleeve, a plurality of bearing grooves are evenly opened on the outer circumference of the turntable body, the turntable body is fixed on the mounting sleeve, the two mounting sleeves are slidably matched with the transmission roller, and the distance between the two mounting sleeves is adjustable.
[0013] A further technical improvement of the utility model is that the number of the bearing grooves is consistent with the number of gaps between the limiting racks.
[0014] A further technical improvement of the utility model is that the support assembly comprises two relatively parallel arc plates, a plurality of rollers are evenly rotatedly mounted between the two arc plates, and the distance between two adjacent rollers is less than one quarter of the diameter of the stainless steel pipe.
[0015] A further technical improvement of the utility model is that a slot is provided on one side of the pickling tank, and a material discharge track is installed at the slot.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. By setting an automatic material trough just above the pickling tank, the stainless steel pipes are automatically divided and transferred to the rotating carrying turntable. Driven by the carrying turntable, the stainless steel pipes are automatically immersed in the pickling solution. After the pickling operation is completed, the automatic carrying turntable is separated and enters the unloading track for unloading, thus realizing the manual pickling process, reducing labor costs, and ensuring the health of personnel;
[0018] 2. The gap between two adjacent limit racks on the material distribution roller can accommodate stainless steel pipes within a certain radius range. Similarly, the bearing groove on the bearing turntable can also accommodate stainless steel pipes within a moving radius range. For the adaptation in the length direction, the two bearing plates and the driving rollers are connected by splines, and the distance between the two is adjustable, so that stainless steel pipes of different lengths can be matched.
