[0027] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0028] Embodiment

[0029] This embodiment provides a coal water slurry stirring structure. Refer to Figures 1 - 4, including a stirring barrel 1, a motor 5 and a stirring member. The stirring barrel 1 is installed with a stirring member inside it through the motor 5. The stirring barrel 1 is provided with a feed pipe 11 and a discharge pipe 9. The stirring member includes a stirring column 4 and stirring blades 8. One end of the stirring column 4 is connected to the motor 5, and the other end is sleeved on the discharge pipe 9. The discharge pipe 9 is provided with discharge holes 10 to make the discharge pipe 9 communicate with the inside of the stirring barrel 1. The stirring barrel 1 is provided with an electric push rod 6. The movable end of the electric push rod 6 is connected to the motor 5 to move the motor 5 and the stirring member away from the discharge pipe 9, so that the discharge holes 10 are exposed inside the stirring barrel 1. The motor 5 drives the stirring member to rotate, which can fully stir the water slurry. When the electric push rod 6 moves the electric stirring member up and down, the stirring blades 8 in contact with the inner wall of the stirring barrel 1 can clean it.

[0030] When the motor 5 works, it drives the stirring column 4 to rotate. The stirring blades 8 installed on the stirring column 4 rotate together with the stirring column 4. The obliquely arranged stirring blades 8 can drive the water slurry to roll when rotating, and can fully stir and mix the water slurry. Since the outer edge of the stirring blade 8 is in contact with the inner wall of the stirring barrel 1, when the stirring blade 8 rotates, it can scrape off the relatively thick water slurry attached to the inner wall of the stirring barrel 1, ensuring the stirring efficiency of the water slurry and cleaning the inner wall of the stirring barrel 1 at the same time;

[0031] When the stirring is sufficient, the electric push rod 6 drives the motor 5 to move upward. Therefore, the stirring column 4 and the stirring blades 8 on the stirring column 4 move upward accordingly. After the stirring column 4 moves upward, the discharge holes 10 sleeved on the bottom discharge pipe 9 of the stirring column 4 are exposed, facilitating the discharge of the water slurry. At the same time, the continuous rotation of the stirring member can scrape and clean the area of the stirring barrel 1 between the multiple stirring blades 8, achieving the effect of stirring the water slurry and cleaning the inner wall of the stirring barrel 1.

[0032] A plurality of flow holes are opened on the stirring blade 8 to enable the water slurry to pass through the flow holes. The water slurry is stirred by the stirring blade 8 and the flow through the flow holes can make the stirring of the water slurry more sufficient. The flow holes are opened perpendicular to the stirring blade 8. So that the flow holes carry out a bypass flow on the water slurry. The flow holes can also increase the fluidity of the water slurry, prevent local overload caused by adhesion. The flow holes also help to reduce the shear force during the stirring process and avoid damage to the motor 5.

[0033] When the stirring blade 8 rotates and the water slurry is driven to roll by the stirring blade 8, the water slurry will also pass through the flow holes. The flow holes can collide and disperse the agglomerated water slurry, further improving the stirring effect of the water slurry. Since the flow holes are opened perpendicular to the stirring blade 8 and the stirring blade 8 is obliquely arranged, when the stirring blade 8 rotates, the flow holes carry out a bypass flow on the water slurry, ensuring the full stirring of the water slurry and no agglomeration in the stirred water slurry.

[0034] A plurality of stirring blades 8 are provided, and the stirring blades 8 are inclined and installed on the outer wall of the stirring column 4 and are spirally distributed along the stirring column 4. When stirring, it can drive the water coal slurry to roll.

[0035] The stirring blades 8 are inclined, and a plurality of stirring blades 8 are arranged in an array on the stirring column 4. The distance between the plurality of stirring blades 8 is the same as the height of the inclined stirring blades 8. When the stirring blades 8 rotate, the attached water coal slurry at the part in contact with the stirring barrel 1 can be scraped off. When the stirring blades 8 move upward, the stirring blades 8 can scrape and clean the area between the stirring blades 8 on the previous stirring barrel 1, and at the same time continue to stir and mix, improving the practicability of the device.

[0036] One end of the stirring blade 8 close to the inner wall of the stirring barrel 1 is an arc structure, and the arc structure is in contact with the inner wall of the stirring barrel 1. It is convenient to be in contact with the inner wall of the stirring barrel 1 to achieve the effect of cleaning the inner wall of the stirring barrel 1.

[0037] One end of the stirring blade 8 with an arc structure abuts against the inner wall of the stirring barrel 1. When the stirring blade 8 rotates, it can fully scrape the inner wall of the stirring barrel 1, realizing the cleaning effect of the inner wall of the stirring barrel 1. The scraped water coal slurry can be mixed with the fully mixed water coal slurry to achieve the effect of fully mixing the water coal slurry.

[0038] The discharge pipe 9 is a pipe body structure with one end open, and the other end is connected to the stirring column 4, and a plurality of discharge holes 10 are provided on the outer wall of this end. The discharge holes 10 are circumferentially distributed on the outer wall of the discharge pipe 9. It is convenient to discharge the water coal slurry, and the bottom of the stirring column 4 can also block the discharge holes 10.

[0039] The bottom of the stirring column 4 has a groove. When the bottom end of the stirring column 4 abuts against the discharge pipe 9, the bottom end of the stirring column 4 can block the discharge holes 10 on the discharge pipe 9, which can prevent the water coal slurry from entering the inside of the discharge pipe 9, can fully stir the water coal slurry, and avoid the water coal slurry from entering the discharge holes 10 and settling. A valve is provided at the bottom of the discharge pipe 9. When discharging is required, the valve is opened, the stirring column 4 moves upward, and the discharge holes 10 are exposed, facilitating the discharge of the stirred water coal slurry.

[0040] The stirring barrel 1 includes a barrel body, a top cover 2 and a bottom plate 3 respectively located at both ends of the barrel body. The top cover 2 and the bottom plate 3 are detachably connected to the barrel body, and a support leg 12 is provided on one side of the bottom plate 3. It is convenient to clean the inside of the stirring barrel 1 and the stirring parts after disassembly. The bottom surface of the discharge hole 10 is lower than the top surface of the bottom plate 3. It is convenient to completely discharge the water coal slurry.

[0041] The barrel body, the top cover 2 and the bottom plate 3 are all detachable. When the device needs to be repaired or maintained after long-term use, it is convenient to disassemble and take out the stirring parts. The support legs 12 can keep the stirring barrel 1 away from the ground, facilitating the discharging work of the discharging pipe 9. The bottom surface of the discharging hole 10 is lower than the top surface of the bottom plate 3, which is convenient for completely discharging the water slurry in the stirring barrel 1 and avoiding the residue of water slurry in the stirring barrel 1, affecting the subsequent stirring work.

[0042] A through hole for the output shaft of the motor 5 to penetrate is provided on the top cover 2, and a sealing ring is provided between the through hole and the output shaft of the motor 5. This facilitates the motor 5 to drive the stirring parts to rotate, and at the same time ensures the sealing performance of the device, preventing the water slurry from seeping out from the output shaft.

[0043] The power output shaft of the motor 5 penetrates the through hole and is connected to the stirring column 4 inside the stirring barrel 1. The sealing ring between the power output shaft of the motor 5 and the through hole can enhance the sealing performance of the stirring barrel 1, preventing the water slurry from seeping out through the gap at the through hole due to the tumbling and mixing of the water slurry during the operation of the stirring barrel 1, and improving the practicality of the device.

[0044] A protective layer is provided on the inner wall of the stirring barrel 1 and the outer wall of the stirring parts. The protective layer includes a wear-resistant layer and an anti-corrosion layer, which can extend the service life of the device.

[0045] To prevent the water slurry from corroding the stirring parts and the inner wall of the stirring barrel 1 under specific conditions, the anti-corrosion layer can effectively extend the service life of the device. At the same time, to avoid damage to the stirring barrel 1 and the stirring parts caused by the long-term rubbing of the stirring blades 8 against the inner wall of the stirring barrel 1, the wear-resistant layer can further extend the service life of the device.

[0046] When the motor 5 rotates in the reverse direction, it can drive the stirring blades 8 to reverse, pushing the water slurry liquid in the stirring barrel 1 towards the bottom of the stirring barrel 1, increasing the discharging speed of the water slurry from the stirring barrel 1. At the same time, while stirring the water slurry scraped from the inner wall of the stirring barrel 1, it flings it towards the bottom of the stirring barrel 1, cleaning it from the inner wall of the stirring barrel 1.

[0047] In this embodiment, the working principle of the water slurry stirring structure is as follows:

[0048] First, add the water coal slurry and the additives to be used into the stirring barrel 1 through the feed pipe 11; then, start the motor 5. The power output shaft of the motor 5 drives the stirring column 4 to rotate, and the stirring column 4 drives the stirring blades 8 to rotate. When the stirring blades 8 rotate, they fully stir the water coal slurry and the additives. At the same time, since the stirring blades 8 are in contact with the inner wall of the stirring barrel 1, when the stirring blades 8 rotate, they can also scrape and clean the inner wall of the stirring barrel 1, ensuring the cleaning of the inner wall of the stirring barrel 1 while fully mixing the water coal slurry; finally, after the water coal slurry is fully stirred, the electric push rod 6 drives the motor 5 to move upward. Since the power output shaft of the motor 5 is connected to the stirring column 4, when the motor 5 moves upward, the stirring column 4 and the stirring blades 8 follow and move upward. The valve in the discharge pipe 9 is opened, the groove at the bottom of the stirring column 4 moves away from the top of the discharge pipe 9, and the stirred water coal slurry can be discharged from the discharge hole 10 out of the stirring barrel 1. At the same time, the stirring column 4 follows the reverse rotation of the motor 5, and the reverse rotation of the stirring blades 8 stirs the water coal slurry scraped from the inner wall of the stirring barrel 1 and flings it towards the bottom of the stirring barrel 1, cleaning it from the inner wall of the stirring barrel 1.

[0049] As mentioned above, the above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes, increases or decreases, or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
