Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, specifically relating to a tool for cleaning the inner wall of a pipe without bends. Background Technology

[0002] Due to the operating environment, the wastewater pipes of currently popular evaporators often accumulate extremely difficult-to-remove scale on their inner walls. Regular descaling of evaporator water pipes is an important task. Traditional descaling methods include mechanical methods (scraping, brushing), high-pressure water cleaning, and chemical cleaning (acid washing). However, chemical cleaning methods cannot completely remove scale and other deposits. Acid can corrode the equipment, creating leaks. Residual acid can cause secondary corrosion or under-deposit corrosion, ultimately leading to equipment replacement. In addition, the cleaning wastewater is toxic and requires significant investment in wastewater treatment. Traditional cleaning methods typically involve using wire brushes with an electric drill, which is time-consuming, labor-intensive, and consumes a lot of wire brushes. Traditional scraping methods can also damage the condenser cooling water pipes, and the scale cannot be completely removed. A device is needed to solve all these problems.

[0003] Moreover, existing descaling devices have a simple structure, cannot be assembled, and cannot be used to remove scale in a targeted manner, resulting in insignificant descaling effects. Utility Model Content

[0004] To address the shortcomings of existing technologies, a tool for cleaning the inner wall of holes in pipes without bends is provided, comprising a base, a T-wedge, and a tool. The bottom of the base is connected to an electric drill bit via an extension rod, and the top of the base is connected to the tool via a T-wedge.

[0005] Furthermore, the base is provided with an extension rod threaded hole at the bottom, and the extension rod threaded hole is connected to the electric drill bit through the extension rod.

[0006] Furthermore, a T-shaped through groove is provided on the top of the base, and the T-shaped through groove is movably connected to a T-shaped wedge.

[0007] Furthermore, the T-shaped wedge is provided with a T-shaped wedge threaded hole.

[0008] Furthermore, the cutting tool is provided with a tool thread hole that penetrates the tool body.

[0009] Furthermore, the T-shaped wedge is connected to the cutting tool via a threaded rod.

[0010] Furthermore, the threaded rod passes through the tool threaded hole and the T-wedge threaded hole in sequence, fixing the T-wedge to the tool.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a tool for cleaning the inner wall of pipes without bends, utilizing an adjustable, movable cutter head to solve the practical problem of difficult-to-clean hard scale on the inner wall of the pipe. The cutter head of this utility model removes scale quickly, significantly saving labor and consumable costs. Cleaning is fast and not easily worn. At the same time, the device's design is convenient and flexible, applicable to cleaning the inner walls of pipes with different inner diameters, and can be adjusted according to actual needs.

[0025] Example 1

[0026] A tool suitable for cleaning the inner wall of a through-hole without bends, such as Figures 1-12As shown, it includes a base 1, a T-shaped wedge 2, and a cutting tool 3. The bottom of the base 1 is connected to the electric drill bit via an extension rod, and the top of the base 1 is connected to the cutting tool 3 via the T-shaped wedge 2.

[0027] The base 1 has an extension rod threaded hole 11 at its bottom, and the extension rod threaded hole 11 is connected to the electric drill bit through the extension rod.

[0028] The base 1 has a T-shaped through groove 12 on its top, which is movably connected to the T-shaped wedge 2.

[0029] The T-shaped wedge 2 is provided with a T-shaped wedge threaded hole 21.

[0030] The cutting tool 3 is provided with a cutting tool thread hole 31 that penetrates the main body of the cutting tool 3.

[0031] The T-shaped wedge 2 is connected to the cutting tool 3 via a threaded rod.

[0032] The threaded rod passes through the tool threaded hole 31 and the T-wedge threaded hole 21 in sequence, and the T-wedge 2 is fixedly connected to the tool 3.

[0033] Example 2

[0034] A tool for cleaning the inner wall of a pipe without bends, comprising a circular fixed base 1, four positioning T-shaped wedges 2 and four movable cutter heads 3.

[0035] An M6 threaded hole is machined at the center of the bottom surface of the fixed base 1 to connect the extension rod.

[0036] The top surface of the base 1 has a cross-shaped T-shaped groove 12. The movable cutter head is fixed inside the T-shaped groove 12 by a positioning T-shaped wedge 2. The distance between the cutter heads can be adjusted according to the diameter of the inner wall of the pipe to perform descaling.

[0037] The center of the positioning T-wedge 2 is machined with an M3 threaded hole, which together with the M3 threaded hole at the center of the cutter head forms a movable part.

[0038] The cutter head has a countersunk hole with a diameter of 4mm at its center to secure the M3 screw for the T-shaped wedge 2. The cutter head also has a chamfered radius of 0.5mm on the outside to prevent damage to the inner wall of the tube during processing.

[0039] In actual use, the electric drill bit selects a suitable extension rod based on the required length of the straight pipe to be descaled. One end of the extension rod needs an M6 thread to connect to the drill bit. Descaling is performed by the electric drill bit, which rotates at high speed. When the drill bit contacts the scale on the inner wall of the pipe, pressure is applied to the drill bit, which is converted into cutting force through rotation and begins to cut the scale. During the cutting process, the rotation of the drill bit and the applied pressure generate a large amount of debris. The rotation of the drill bit continues to expel these debris from the hole, ensuring successful descaling.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
