DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-4 As shown, an internal cleaning device for a powder storage tank includes a tank body 1, a cleaning component, a water supply component, a connecting sleeve 3 and a shoveling sleeve 4. The connecting sleeve 3 is installed at the front end of the tank body 1, and the shoveling sleeve 4 is installed on the outside of the connecting sleeve 3, which can not only remove stubborn lumps, but also protect the side of the cleaning component. The cleaning component and the water supply component are both installed in the tank body 1, and the front end of the cleaning component extends out of the connecting sleeve 3 to clean the inner wall of the storage tank. An air inlet 18 and a water inlet 19 are provided on the tank body 1. The air inlet 18 is connected to the cleaning component, and the water inlet 19 is connected to the water supply component to provide power and water flow for cleaning.

[0024] In the above embodiment, the cleaning assembly includes an air motor 12, a connecting rod 13 and a brush head 14 connected in sequence. The air motor 12 is installed in the tank body 1 and communicated with the air inlet 18. The connecting rod 13 passes through the connecting sleeve 3. The front end of the brush head 14 extends out of the connecting sleeve 3 to scrub the inner wall of the storage tank. The brush head 14 is rotatably connected to the connecting sleeve 3 through a bearing, which assists the brush head 14 in receiving force and prevents the connecting rod 13 or the brush head 14 from being deformed or damaged during the transmission distance process. The water supply assembly includes a water pump 15 and a water pipe. The water pump 15 is installed in the tank body 1. The front end of the connecting sleeve 3 is provided with a water outlet 11, which is communicated with the water pump 15 through a water pipe. Water flows continuously from the water outlet 11 to scrub the inner wall of the storage tank with the brush head 14, thereby enhancing the scrubbing effect. The connecting sleeve 3 is connected to the shoveling sleeve 4 through a spring 5, and a groove 8 is provided on the outer wall of the connecting sleeve 3, and a buckle 7 is provided on the inner wall of the shoveling sleeve 4. The buckle 7 can be elastically clamped in the groove 8 through the spring 5. At this time, the shoveling sleeve 4 protrudes from the front end of the brush head 14, and the middle space of the shoveling sleeve 4 is helpful for discharging when shoveling away powder lumps; an annular boss 10 is provided on the outer wall of the connecting sleeve 3, and an annular groove 9 is provided on the inner wall of the shoveling sleeve 4. The spring 5 is located in the annular groove 9, one end of the spring 5 abuts against the side of the annular groove 9, and the other end abuts against the side of the annular boss 10. When the buckle 7 leaves the groove 8, it can automatically rebound and reset, so that the brush head 14 protrudes from the shoveling sleeve 4.

[0025] In the above embodiment, the front end of the shoveling sleeve 4 is a spiral structure 6, which provides multiple shoveling parts of different shapes to adapt to various scenarios. The tank body 1 is provided with a handle to facilitate adjustment by the staff; the tank body 1 is provided with a shoulder strap 17 to assist in force during operation and facilitate adjustment of the angle of the device. The tank body 1 is connected to the connecting sleeve 3 through an extension tube 2 to facilitate cleaning of the top area of ​​the inner wall of the storage tank; the extension tube 2 is provided with anti-slip grooves to facilitate one-handed holding.

[0026] Description of the working method of this utility model:

[0027] After the powder storage tank has been used for a certain period of time, or before changing the type of powder, it is necessary to thoroughly clean the inside of the storage tank to deal with the lumps that appear on the inner wall of the storage tank after long-term use, so as to avoid affecting the new material when re-stocking. After the inside of the powder storage tank is emptied, a headlight is set up at the tank mouth, and the sewage outlet at the bottom of the storage tank is opened, and the staff enters the tank to clean it. Before carrying the device into the tank, the air inlet 18 and the water inlet 19 need to be connected to the air source and the water source respectively, and the ventilation and water test device is used normally; after entering the tank, the air source and the water source are introduced into the device at the same time, and the flushing and brushing functions can be started. Under the brushing of the brush head 14 and the impact of the water flow, the powder and lumps are taken away from the sewage outlet by the water flow. For some stubborn lumps, the shoveling sleeve 4 can be pushed out and slid into the card slot 8 with the buckle 7, and the shoveling sleeve 4 is fixed under the reaction force of the spring 5, and the spiral structure 6 at the front end of the shoveling sleeve 4 is used to shovel the lumps, so as to further improve the brushing effect; after the lumps are removed, slide and rotate the shoveling sleeve 4 to remove the buckle 7 from the card slot 8. At this time, the shoveling sleeve 4 automatically resets under the action of the spring 5, and the brush head 14 protrudes from the shoveling sleeve 4 again to continue cleaning.

[0028] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
