[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0020] Combining the diagram and Figure 2 As shown, a high-efficiency cleaning mechanism for the inner wall of a seamless stainless steel pipe includes a cylinder 1, a nozzle 2 fixed inside the cylinder 1, and a brush head rotatably connected to the front end of the cylinder 1.
[0021] A set of rollers 3 is provided on the outer side of the front and rear ends of the cylinder 1 to facilitate the cylinder 1 to move back and forth along the axial direction inside the steel pipe.
[0022] The brush head is composed of a connecting ring 4 and a brush head body 9. The front end of the cylinder 1 has a connecting part 5 corresponding to the connecting ring 4. The rear end of the connecting ring 4 is rotatably connected to the connecting part 5 through a bearing 6. A central shaft 7 is also provided inside the front end of the connecting ring 4. Multiple blades 8 are also obliquely connected between the connecting ring 4 and the central shaft 7. The brush head body 9 is fixed on the outer periphery of the connecting ring 4.
[0023] The nozzle 2 has its outlet facing the central axis 7, and the rear end of the nozzle 2 is connected to a pipe 10, which is connected to the water storage tank via a pump.
[0024] The working principle of the above structure is as follows: Insert the end of the mechanism with the brush head into the steel pipe, start the pump, and slowly push the mechanism into the steel pipe by holding the connecting pipe; spray water from the nozzle 2 towards the inside of the steel pipe, and the water flow from the nozzle 2 impacts the blades 8 inside the brush head, causing the water flow to spray around the inner wall of the steel pipe. At the same time, the blades 8 drive the brush head to rotate, so that the brush head body 9 on the brush head abuts against and scrapes the inner wall of the steel pipe, thus cleaning the inner wall of the steel pipe efficiently.
[0025] The advantages of the above structure are: simple structure and low manufacturing cost; while rinsing the inner wall of the steel pipe, it also brushes the inner wall of the steel pipe, which can achieve efficient cleaning of stainless steel seamless steel pipes; the water sprayed from the nozzle 2 also drives the brush head to rotate, without the need for additional power.
[0026] In another embodiment, combined Figure 1 and Figure 2 As shown, there are four rollers in each of the two sets 3, and the two sets of rollers 3 are distributed in a cross shape on the outer periphery of the cylinder 1.
[0027] In another embodiment, combined Figure 1 and Figure 2 As shown, the cylinder 1 is provided with mounting grooves corresponding to each roller 3, and each roller 3 is set in the corresponding mounting groove. Multiple limiting plates 11 with clearance grooves are also fixed on the outside of the cylinder 1. Each limiting plate 11 is fixed on the cylinder 1 to limit each roller 3, so as to facilitate the assembly of each roller 3.
[0028] In another embodiment, such as Figure 1 As shown, the brush head body 9 is composed of an elastic ring and multiple brush bodies arrayed around the outer periphery of the elastic ring, so that the brush head body 9 has a certain elasticity, can better fit the inner wall of the steel pipe, and avoid the brush head body 9 getting stuck inside the steel pipe.
[0029] In another embodiment, such as Figure 1 As shown, a fixing frame 12 is provided inside the cylinder 1. The fixing frame 12 has an internal thread, and the nozzle 2 has a corresponding external thread. The nozzle 2 is screwed onto the fixing frame 12 to facilitate the assembly of the nozzle 2.
[0030] In another embodiment, such as Figure 1 As shown, the fixing frame 12 is located in the middle of the cylinder 1 to balance the center of gravity of the entire mechanism.
[0031] In another embodiment, such as Figure 1As shown, the nozzle 2 is further provided with a limiting ring 13 at its rear end. The limiting ring 13 abuts against the rear end of the cylinder 1 to limit the depth to which the nozzle 2 is screwed into the cylinder 1.
[0032] In another embodiment, such as Figure 1 As shown, the connecting part 5 is a thickened connecting part 5, and the cross-section of the connecting part 5 is a trumpet shape that is narrow on the outside and wide on the inside, so as to improve the reliability of the connecting part 5.
[0033] In another embodiment, the outer diameter of the brush head body 9 corresponds to the inner diameter of the steel pipe, and the outer diameter of the projected outer circle of each set of rollers 3 corresponds to the inner diameter of the steel pipe.
