DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] An inner wall anti-adhesion and corrosion-resistant steel-lined plastic storage tank includes a tank body 1 and a cleaning component. An inlet 101 is provided on the top surface of the tank body 1, an outlet 102 is provided on the bottom surface of the tank body 1, and a pressure sensor 103 and a pressure balance valve 104 are provided on the side wall of the tank body 1.

[0025] The cleaning component includes a main shaft 2. The main shaft 2 is rotatably connected to the top surface of the tank body 1. A sealing bearing is provided at the rotational connection of the main shaft 2 and the tank body 1. One end of a connecting rod 201 is fixedly connected to the lower end of the main shaft 2, the other end of the connecting rod 201 is fixedly connected to a rotating shaft 202, a sleeve shaft 203 is connected to the rotating shaft 202 with a clearance, a torsion spring 204 is provided between the rotating shaft 202 and the sleeve shaft 203, and one end of a scraping plate 205 is installed on the outer side of the sleeve shaft 203.

[0026] The length of the scraping plate 205 is greater than the distance between the sleeve shaft 203 and the inner wall of the tank body 1. The other end of the scraping plate 205 is provided with a rounded corner, and the rounded corner is adapted to the inner wall of the tank body 1.

[0027] Since the length of the scraping plate 205 is greater than the distance between the sleeve shaft 203 and the inner wall of the tank body 1, and a torsion spring 204 is provided between the scraping plate 205 and the sleeve shaft 203, in the normal state, the scraping plate 205 will tightly abut against the inner wall of the tank body 1 due to the torsion of the torsion spring 204. This design can reduce the distance between the scraping plate 205 and the inner wall of the tank body 1, making the cleaning effect of the device better.

[0028] The inner wall of the tank body 1 can be cleaned by using the scraping plate 205, preventing materials from adhering to the inner wall of the tank body 1, keeping the inside of the tank body 1 clean, improving the service life of the storage tank, and reducing problems such as the reduction of the capacity of the tank body 1 caused by adhesion on the inner wall.

[0029] The rounded corner design and appropriate length of the scraping plate 205 can better fit the inner wall, and with the assistance of structures such as the torsion spring 204, the cleaning effect is more comprehensive and efficient.

[0030] One end of an extension piece is provided on the outer side of the top end of the main shaft 2, and a sleeve handle is provided at the other end of the extension piece.

[0031] By setting the extension piece and the sleeve handle, during operation, the operator can hold the sleeve handle and rotate the device. Compared with holding the smooth surface of the main shaft 2, the sleeve handle has a larger contact area and the advantages of not needing to frequently release and hold, and adjust the arm direction, etc., which can make it more convenient for the operator to use.

[0032] Furthermore, a hydrophobic hole 3 is provided on the top surface of the main shaft 2, a connecting groove 301 is provided in the connecting rod 201, a communicating cavity 302 is provided in the rotating shaft 202, a docking cavity 303 is provided in the scraping plate 205, the hydrophobic hole 3, the connecting groove 301, the communicating cavity 302, and the docking cavity 303 are interconnected, and a water outlet hole 305 communicating with the surface of the scraping plate 205 is provided in the docking cavity 303. There are multiple water outlet holes 305, which are linearly arrayed and spaced on the scraping plate 205.

[0033] By adopting the above design, during cleaning, the appropriate cleaning liquid can be selected according to the previously stored solution characteristics, and then the cleaning liquid is pumped into the hydrophobic hole 3 through an electric or manual pump, and after passing through the connecting groove 301, the communicating cavity 302, and the docking cavity 303, it is sprayed out from the water outlet hole 305. When the device is being cleaned, the cleaning liquid can be sprayed while scraping, which can accelerate the peeling and dissolution of the liquid residue on the inner wall, and help improve the cleaning effect and speed of the device.

[0034] A connecting pipe 304 is provided between the communicating cavity 302 and the docking cavity 303, and the connecting pipe 304 is a corrugated pipe.

[0035] The design of the corrugated pipe enables the connecting pipe 304 to deform freely, so as to adapt to the misalignment between the communicating cavity 302 and the docking cavity 303, making its connection more stable and the sealing better.

[0036] A plurality of elastic pieces are provided in the water outlet hole 305, the top ends of the elastic pieces are located outside the water outlet hole 305, and the ends are located on the arc surface of the water outlet hole 305.

[0037] The design of the elastic pieces makes it so that when the device stores the solution, the pressure of the solution will not open the elastic pieces, which can prevent the solution from entering the docking cavity 303 and being difficult to clean, or even the situation where the solution gushes out along the directions of the communicating cavity 302, the connecting groove 301, and the hydrophobic hole 3 from the docking cavity 303.

[0038] Working principle:

[0039] In use, first hold the sleeve handle and rotate the main shaft 2 to drive the scraper 205 to rotate. Since the length of the scraper 205 is greater than the distance between the sleeve shaft 203 and the inner wall of the tank body 1, and a torsion spring 204 is provided between the scraper 205 and the sleeve shaft 203, in the normal state, the scraper 205 will be tightly in contact with the inner wall of the tank body 1 due to the torsion force of the torsion spring 204. This design can reduce the distance between the scraper 205 and the inner wall of the tank body 1, making the cleaning effect of this device better.

[0040] Moreover, during cleaning, an appropriate cleaning liquid can be selected according to the solution characteristics stored previously. Then, the cleaning liquid is pumped into the hydrophobic holes 3 through an electric or manual pump, and is sprayed out from the water outlet holes 305 after passing through the connecting groove 301, the communication cavity 302, and the docking cavity 303. When this device is cleaning, it can scrape and spray the cleaning liquid at the same time, which can accelerate the peeling and dissolution of the liquid residue on the inner wall, and help improve the cleaning effect and speed of this device.
