Description

Technical Field

[0001] This utility model belongs to the field of manufacturing processing technology, and specifically relates to a cleaning device for stainless steel storage tanks. Background Technology

[0002] Stainless steel storage tanks are storage containers made of stainless steel and are widely used in the food, pharmaceutical, chemical, and petroleum industries. Stainless steel resists corrosion from air, water, and chemical media. The fully enclosed design prevents contaminants from entering, ensuring the purity of the stored liquid. This makes them particularly suitable for hygiene-sensitive areas such as food and pharmaceuticals. Sediment at the bottom of the tank can be cleaned periodically via a drain valve, eliminating the need for frequent cleaning and reducing the risk of contamination. They can withstand high-pressure environments and are equipped with lightning protection and anti-static grounding devices, meeting safety standards. However, traditional cleaning methods for the inside of stainless steel storage tanks require internal spraying, but residual dirt on the inner walls cannot be wiped clean, requiring additional brush cleaning by staff, which is time-consuming and labor-intensive. Furthermore, single cleaning devices are unsuitable for cleaning various sizes of stainless steel storage tanks, necessitating the preparation of multiple cleaning devices or additional manual cleaning, resulting in low applicability. To address the problems mentioned above, we propose a cleaning device for stainless steel storage tanks. Utility Model Content

[0003] The purpose of this utility model is to provide a cleaning device for stainless steel storage tanks, which has the advantages of rotating and lifting for cleaning and adaptability to multiple specifications.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cleaning device for stainless steel storage tanks, comprising a top plate, a screw rod rotatably connected through and to the left side of the top and bottom of the top plate, a fixed frame rotatably connected through and to the middle of the surface of the screw rod, a threaded sleeve connected to the bottom of the surface of the screw rod, limit frames bolted to both sides of the bottom of the fixed frame, a bearing rotatably connected to the bottom of the threaded sleeve, a turntable sleeved on the bottom of the bearing, a sprocket B fixedly sleeved on the surface of the fixed frame, a chain meshing on the left side of the sprocket B, a sprocket A meshing on the right side inside the chain, a horizontal bevel gear fixedly sleeved on the top of the screw rod, a vertical bevel gear meshing on the right side of the horizontal bevel gear, and a cleaning mechanism provided on the surface of the turntable.

[0005] The above technical solution involves the following: the vertical bevel gear rotates, driving the horizontal bevel gear to rotate; the horizontal bevel gear drives the screw to rotate; the screw rotates, causing the screw sleeve to move up and down; the screw sleeve moves, causing the turntable to move; and the cleaning mechanism to move up and down. Motor B drives sprocket A to rotate; sprocket A drives the chain to rotate; the chain drives sprocket B to rotate; sprocket B drives the telescopic rod to rotate; the telescopic rod drives the turntable to rotate; and the turntable drives the cleaning mechanism to rotate. This system uses a spiral trajectory to cover the inner wall of stainless steel storage tanks of various heights, solving the problem of blind spots in planar cleaning and achieving full-height coverage of the inner wall from bottom to top of the tank. No manual adjustment of the brush angle or climbing the tank is required. This device is superior to single-mode equipment in terms of compatibility, cleaning power, and ease of operation, and is highly efficient.

[0006] The present invention is further configured such that the cleaning mechanism includes a bracket, the bracket being bolted to the front, back and sides of the turntable surface, and connecting rods being hinged to the two sides of the inner wall of the bracket, with a brush sleeved at the bottom of the connecting rod.

[0007] The above technical solution employs a cleaning mechanism. Motor B drives sprocket A to rotate, sprocket A drives the chain to rotate, the chain drives sprocket B to rotate, sprocket B drives the telescopic rod to rotate, the telescopic rod drives the turntable to rotate, the turntable drives the support to rotate, and the support drives the connecting rod to rotate. The connecting rod, hinged to the support, expands outward due to centrifugal force during rotation. The connecting rod drives the brush to rotate and expand. During rotation, the brush expands radially under centrifugal force, eliminating the need for manual adjustment of the brush diameter. The brush assembly automatically extends to reach the tank wall during rotation, autonomously adapting to different tank diameters and achieving self-adaptive adjustment. This improves the efficiency of removing stubborn stains, effectively solving the cleaning adaptation problem in the production of multi-specification tanks, and demonstrating high applicability.

[0008] The present invention is further configured such that a motor A is fixedly sleeved inside the vertical bevel gear, and the right side of the motor A is embedded in the top left side of the top plate; a motor B is fixedly sleeved inside the sprocket A, and the top of the motor B is embedded in the right side of the bottom of the top plate.

[0009] The above technical solution involves setting up motor A and motor B to drive the vertical bevel gear and sprocket A to rotate.

[0010] The present invention is further configured such that sliders are bolted to both sides of the screw sleeve, and a sliding groove is provided on the opposite side of the two limiting brackets, and the interior of the sliding groove is slidably connected to the surface of the slider.

[0011] The above technical solution uses a slider and a groove to limit the movement of the threaded sleeve.

[0012] The present invention is further configured such that the screw sleeve is in the shape of a cuboid.

[0013] By adopting the above technical solution, by setting it as a cuboid, the limiting bracket can limit the screw sleeve, preventing it from remaining stationary.

[0014] The present invention is further configured such that telescopic rods are welded to both sides of the bottom of the sprocket A, and the bottom of the telescopic rods is bolted to both sides of the top of the turntable.

[0015] The above technical solution utilizes a telescopic rod to stabilize the turntable and facilitate its movement.

[0016] The present invention is further configured such that a support column is bolted to the right side of the top plate.

[0017] The above technical solution involves setting up support columns to support the device.

[0018] The present invention is further configured such that a base is bolted to the bottom of the support column.

[0019] The above technical solution uses a base to stabilize the device.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model solves the problem of blind spots in planar cleaning by covering the inner wall of stainless steel storage tanks of various specifications and heights with a spiral trajectory, achieving full height coverage of the inner wall from the bottom to the top of the tank. There is no need to manually adjust the brush head angle or climb the tank. This device is superior to single-motion mode devices in terms of compatibility, cleaning power and ease of operation, and is highly efficient.

[0022] 2. This utility model utilizes the radial expansion of the brush under centrifugal force during rotation, eliminating the need for manual adjustment of the brush head diameter. The brush assembly automatically extends to reach the can wall during rotation, allowing it to adapt to different can diameters and achieve self-adjustment. This improves the efficiency of removing stubborn stains and effectively solves the cleaning adaptation problem in the production of cans of various sizes, making it highly applicable.
