Description

Technical Field

[0001] The utility model relates to the technical field of pipe wall cleaning, in particular to a pipe wall cleaner based on inner lining polyfluoroethylene. Background Art

[0002] The PTFE lined pipe is a steel-PTFE composite pipe that is resistant to strong acids and alkalis. After years of actual use, the factors that directly affect the service life and stable performance of the PTFE lined anti-corrosion pipe are temperature, pressure, medium, etc. High-quality materials and advanced manufacturing processes are the quality guarantee of PTFE lined products. The steel-lined PTFE straight pipe is commonly known as a loose liner pipe. The lined PTFE pipe is a pipe in which the lined PTFE pipe is sheathed in the pipe body. Before sheathing, the inner wall of the pipe body needs to be cleaned. After searching, the Chinese patent with publication number CN217027425U discloses a pipe wall cleaning machine, including a cleaning motor, the output shaft of the cleaning motor is rotatably connected to a seat, and a support rod assembly is fixedly connected to the seat; the output shaft of the cleaning motor is equipped with a plurality of pipe wall cleaning components arranged at intervals on the left and right, and the pipe wall cleaning components include end seats arranged at intervals on the left and right, and a plurality of pipe wall cleaning parts are fixedly connected between the end seats, and the pipe wall cleaning is The utility model comprises an elastic rubber rod fixedly connected to the end seat body, and a plurality of cleaning brush plates arranged at intervals on the left and right are fixedly connected to the elastic rubber rod, and the cleaning brush plates have bristles; the pipe wall cleaning machine also comprises a sludge breaking component fixedly mounted on the pipe wall cleaning component at the left end position. When in use, the operator holds the handle body and extends the pipe wall cleaning component into the pipe. Since the elastic rubber rod is elastic, after the cleaning brush plate is squeezed by the pipe wall, the elastic rubber rod is appropriately bent and deformed, thereby ensuring that the cleaning brush plate can be fully squeezed on the pipe wall, and the cleaning motor is turned on. At this time, the cleaning brush plate follows the rotation and continuously cleans the sludge on the pipe wall. However, it is not convenient to inject cleaning liquid into the pipe body. The cleaning brush plate is used to directly clean the pipe wall, so that the cleaning brush plate causes greater damage to the inner wall of the pipe, and it is easy to damage the flatness of the inner wall of the pipe. At the same time, after the brushing is completed, there is still a layer of dust attached to the inner wall of the pipe due to the dust caused, and the cleanliness is not enough.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example:

[0021] See also Figure 1-3A pipe wall cleaner based on PTFE lining comprises a pipe body 1 and a central axis 2, a front baffle 4 and a rear baffle 3 which can be sealed and slidably matched with the inner wall of the pipe body 1 are fixedly connected to the central axis 2, the top of the rear baffle 3 is inclined toward the side away from the front baffle 4, a cleaning cavity is formed between the front baffle 4 and the rear baffle 3 and the inner wall of the pipe body 1, a brushing mechanism is arranged between the front baffle 4 and the rear baffle 3, a drying mechanism rotatably connected to the central axis 2 is arranged on the side of the rear baffle 3 away from the front baffle 4, a push-pull seat 13 is fixedly connected to the end of the central axis 2 away from the front baffle 4, and the push-pull seat 13 is used to facilitate the pushing of the whole into the pipe body 1.

[0022] Specifically, it also includes two sets of driving mechanisms, which are used to drive the cleaning and brushing mechanism and the blowing and drying mechanism respectively. The cleaning and brushing mechanism and the blowing and drying mechanism are driven by the two sets of driving mechanisms respectively, which is convenient for starting them separately. The blowing and drying operation of the blowing and drying mechanism can be maintained without cleaning, thereby ensuring the blowing and drying effect.

[0023] Specifically, the brush cleaning mechanism includes a brush wall frame 5 rotatably connected to the central axis 2, and a plurality of brush blocks 8 are fixedly mounted on the brush wall frame 5 and slidably cooperate with the inner wall of the tube body 1. By rotating the brush wall frame 5, the inner wall of the tube body 1 can be cleaned by the plurality of brush blocks 8.

[0024] Specifically, the drying mechanism includes a fan blade 6 rotatably connected to the central axis 2. By rotating the fan blade 6, it is convenient to blow air, so that the inner wall of the tube body 1 after brushing is dried, and the cleaning liquid is prevented from sticking to the inner wall, which makes it easy for dust to adhere.

[0025] Specifically, it also includes a guide cover 7, which is arranged on the side of the fan blade 6 away from the rear baffle 3 and is fixedly connected to the central axis 2. The guide cover 7 is convenient for shielding the middle part of the tube body 1, allowing the air flow to flow through the side wall of the tube body 1, thereby improving the efficiency of drying.

[0026] Specifically, the driving mechanism includes a driving motor 10 and an auxiliary shaft 11. The auxiliary shaft 11 is rotatably connected to the central shaft 2. Both ends of the auxiliary shaft 11 are respectively connected to the fan blades 6 and the output shafts of the driving motor 10 through transmission components. The driving motor 10 is started, and the auxiliary shaft 11 is driven to rotate through the transmission component between the auxiliary shaft 11. Through another set of transmission components, the fan blades 6 are driven to rotate. The driving motor 10 that drives the cleaning brush mechanism is fixedly connected to the rear baffle 3 through the fixing frame 9. The driving motor 10 that drives the cleaning brush mechanism is fixedly connected to the side of the front baffle 4 away from the rear baffle 3. Furthermore, the transmission component includes two meshing bevel gears 12, which facilitates transmission.

[0027] When in use, the front baffle plate 4 is first pushed into the tube body 1 through the central axis 2, and then pushed to the bottom of the rear baffle plate 3 and pushed into the tube body 1, and then the cleaning liquid can be added from the side wall of the rear baffle plate 3 and the tube body 1 to the gap between the rear baffle plate 3 and the front baffle plate 4, and then continue to push into the tube body 1 until the rear baffle plate 3 is completely pushed into the tube body 1, so that the cleaning cavity is in a closed form, and the cleaning liquid soaks the inner wall of the tube body 1 at the position of the cleaning cavity, and then the cleaning brush mechanism is started to clean the part soaked with the cleaning liquid through the cleaning brush. Brush, and during the operation, the cleaning brush mechanism contacts the cleaning liquid, cleans the cleaning brush mechanism, ensures the cleaning effect, and at the same time, the scraped sludge brush falls into the cleaning liquid, and then continues to push the cleaning cavity forward to thoroughly clean the entire inside of the tube body 1. After cleaning, the cleaning part is blown dry by the drying mechanism. At the end of the tube body 1, after cleaning, when the front baffle 4 slides out from the end of the tube body 1, the cleaning liquid containing dirt flows out, and then the remaining dirt continues to be scraped out through the rear baffle 3.
