Description

Technical Field

[0001] This utility model relates to the field of aluminum tube processing technology, specifically to an aluminum tube pickling device. Background Technology

[0002] Aluminum tubing is a type of non-ferrous metal tubing made from pure aluminum or aluminum alloy through an extrusion process. It has a hollow structure along its entire longitudinal length and is lightweight, corrosion-resistant, and easy to process. It is widely used in transportation, construction, electronics, agricultural machinery, and household goods.

[0003] Currently, aluminum tubes undergo pickling during processing. Aluminum tube pickling is an important surface treatment process, mainly used to remove oxide layers, oil stains, and other contaminants from the surface of aluminum tubes, providing a clean base for subsequent processing or anti-corrosion treatment. Currently, existing aluminum tube pickling equipment lacks a pushing structure, requiring manual pushing of the aluminum tubes or the use of drive or lifting equipment to move them. Therefore, an aluminum tube pickling device is proposed, which uses a geared motor to drive a rubber grooved wheel to rotate, pushing the aluminum tube to move. An acid and alkali resistant self-priming pump extracts acid solutions such as nitric acid and mixed solutions from the tank to pickle the moving aluminum tube within the tank. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an aluminum tube pickling device. A geared motor drives a rubber grooved wheel to rotate, which in turn moves the aluminum tube. An acid and alkali resistant self-priming pump extracts acid solutions such as nitric acid and mixed solutions from the tank to pickle the moving aluminum tube.

[0005] The technical solution adopted by this utility model to solve its technical problem is an aluminum tube pickling device, including a box body. A pickling assembly is provided on one side of the box body. The pickling assembly includes an acid and alkali resistant self-priming pump installed on one side of the box body through a mounting bracket. The discharge end of the acid and alkali resistant self-priming pump is connected to a liquid outlet pipe through a pipe joint. A structural pipe is welded to the end of the liquid outlet pipe at the top of the box body. Circular annular pipes are provided at both ends of the bottom of the structural pipe inside the box body. Spray nozzles are connected at equal intervals to the inner side of the circular annular pipes through threaded grooves. The box body is provided with a pusher assembly at both ends. The pusher assembly includes a structural seat fixed to both ends of the box body by bolts. A rubber groove wheel is rotatably connected inside the structural seat through a bearing. A geared motor is installed on one side of the structural seat through a mounting bracket.

[0006] By adopting the above technical solution, the geared motor drives the rubber groove wheel to rotate and push the aluminum tube to move. The acid and alkali resistant self-priming pump works to draw out acid solutions such as nitric acid and mixed plugs and spray them out through the nozzle, which can pickle the aluminum tube moving inside the annular tube.

[0007] Specifically, a filter screen is fixed inside the box with bolts, structural plates are fixed to both sides of the box with bolts, and a grooved roller is mounted on the top of the structural plate by a mounting bracket.

[0008] Specifically, the box body has reserved slots at both ends, and the structural base is fixed to the two ends of the box body located at the bottom of the reserved slots by bolts.

[0009] Specifically, the feed end of the acid and alkali resistant self-priming pump is connected to a connecting pipe through a pipe joint, and the end of the connecting pipe away from the acid and alkali resistant self-priming pump is located inside the housing.

[0010] Specifically, the output shaft on one side of the geared motor is connected to the rotating shaft of the rubber groove wheel via a connecting sleeve.

[0011] Specifically, the box body has a door hinged to one side of the top of the filter screen.

[0012] The beneficial effects of this utility model are: (1) The aluminum tube pickling device described in this utility model has a geared motor driving a rubber groove wheel to rotate, which can push the aluminum tube to move, so that the aluminum tube can move through the box. The acid and alkali resistant self-priming pump works to extract acid liquids such as nitric acid and mixed plugs from the box and spray them out through the nozzle, which can pickle the aluminum tube moving in the box.

[0013] (2) In the aluminum tube pickling device described in this utility model, the acid sprayed during pickling falls due to its own weight. The acid falls to the bottom of the box through the filter screen so that it can be reused. Impurities and particulate matter washed off the surface of the aluminum tube can be filtered out by the filter screen. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] A geared motor drives a rubber grooved wheel to rotate, propelling the aluminum tube forward. An acid- and alkali-resistant self-priming pump extracts nitric acid, mixed solutions, and other acidic liquids from the tank, performing acid pickling on the moving aluminum tube. Figure 1-4 As shown, the aluminum tube pickling device of this utility model includes a housing 1. A pickling assembly 2 is provided on one side of the housing 1. The pickling assembly 2 includes an acid and alkali resistant self-priming pump 201 installed on one side of the housing 1 via a mounting bracket. The discharge end of the acid and alkali resistant self-priming pump 201 is connected to a liquid outlet pipe 202 via a pipe joint. A structural pipe 203 is welded to the end of the liquid outlet pipe 202 located at the top of the housing 1. Circular annular pipes 204 are provided at both ends of the structural pipe 203 located at the bottom inside the housing 1. Spray nozzles 205 are equidistantly connected to the inner side of the circular annular pipes 204 via threaded grooves. The box body 1 is provided with a pusher assembly 3 at both ends. The pusher assembly 3 includes a structural seat 301 fixed to both ends of the box body 1 by bolts. A rubber groove wheel 302 is rotatably connected inside the structural seat 301 through a bearing. A geared motor 303 is installed on one side of the structural seat 301 through a mounting bracket.

[0018] In use, the geared motor 303 drives the rubber groove wheel 302 to rotate and push the aluminum tube to move. The acid and alkali resistant self-priming pump 201 works to draw out acid solutions such as nitric acid and mixed liquids and spray them out through the nozzle 205, which can pickle the aluminum tube moving inside the annular tube 204.

[0019] For example, such as Figure 2 As shown, the present invention also includes a filter screen 4 fixed inside the box 1 by bolts, structural plates 5 fixed on both sides inside the box 1 by bolts, and a grooved roller 6 mounted on the top of the structural plate 5 by a mounting bracket.

[0020] In use, the filter screen 4 is used to filter the acid solution, and the grooved roller 6 is used to assist the aluminum tube in moving within the housing 1.

[0021] For example, such as Figure 1 As shown, the present invention also includes a reserved groove 7 at both ends of the box body 1, and the structural base 301 is fixed to the two ends of the box body 1 located at the bottom of the reserved groove 7 by bolts.

[0022] When in use, the reserved slot 7 facilitates the entry and exit of the aluminum tube into the box 1.

[0023] For example, such as Figure 3As shown, the present invention also includes a connecting pipe 206 connected to the feed end of the acid and alkali resistant self-priming pump 201 through a pipe joint, and the end of the connecting pipe 206 away from the acid and alkali resistant self-priming pump 201 is located inside the housing 1.

[0024] When in use, the acid and alkali resistant self-priming pump 201 works by drawing out acidic liquids such as nitric acid and mixed liquids from the tank 1 or container through the connecting pipe 206.

[0025] For example, such as Figure 4 As shown, this utility model also includes a geared motor 303 whose output shaft on one side is connected to the rotating shaft of the rubber grooved wheel 302 via a connecting sleeve.

[0026] During use, the geared motor 303 drives the rubber grooved wheel 302 to rotate.

[0027] For example, such as Figure 1 As shown, the present invention also includes a door 8 hinged to one side of the housing 1 located at the top of the filter screen 4.

[0028] When in use, opening the door 8 allows you to remove the impurities, particulate matter, etc. filtered out from the filter screen 4.

[0029] When using this utility model, the personnel connect the device to an external power source using a power cord, open the box door 8, and pour acidic solutions such as nitric acid and mixed solutions into the box body 1. Turn on the geared motor 303 to drive the rubber grooved wheel 302 to rotate. Place one end of the degreased and washed aluminum tube on the rubber grooved wheel 302. The rotating rubber grooved wheel 302 pushes the aluminum tube to move, so that one end moves from the reserved groove 7 into the box 1. The aluminum tube that enters the box 1 passes through the annular tube 204 and then extends out from the reserved groove 7 at the other end of the box 1. Finally, the pusher assembly 3 at the other end of the box 1 pushes the aluminum tube to move, so that the aluminum tube can move in the box 1 without manual pushing. The acid and alkali resistant self-priming pump 201 is turned on and the acid solution such as nitric acid and mixed plug is drawn out from the tank 1 through the connecting pipe 206 and transported to the structural pipe 203 through the outlet pipe 202. Then it flows into the annular pipe 204 and is sprayed out through multiple nozzles 205. The surface of the moving aluminum tube in the annular pipe 204 can be pickled. If the pickling effect is not good, the operation can be repeated until the aluminum tube pickling meets the standard. After pickling, the nitric acid, mixed acid, and other acid solutions fall due to their own weight. The acid solution falls through the filter screen 4 to the bottom of the box 1 for reuse. Impurities and particulate matter washed off the surface of the aluminum tube can be filtered out by the filter screen 4. After pickling is completed, personnel can open the box door 8 to remove the impurities and particulate matter on the filter screen 4.
