Detailed Implementation

[0023] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 As shown in the figure, an adjustable paddle mixer according to an embodiment of the present invention includes a drive device 1, a main shaft 2, a hub 3, main blades 4, auxiliary blades 5, and an adjustment device 6. The drive device 1 is disposed above a water tank, the main shaft 2 is disposed below the drive device 1 and connected to the drive device 1, the hub 3 is disposed at the bottom end of the main shaft 2 and fixedly connected to the main shaft 2, the main blades 4 are connected to the hub 3 through the adjustment device 6, and the auxiliary blades 5 are disposed at the end of the main blades 4 away from the hub 3.

[0025] In one type of adjustable paddle mixer with the above structure, an adjustment device 6 is provided at the connection between the hub 3 and the main blade 4. The running angle of the main blade 4 can be adjusted by the adjustment device 6 according to the actual working conditions, thereby increasing or decreasing the stirring effect at the bottom of the pool. At the same time, an auxiliary blade is provided at the end of the main blade 4 away from the hub 3. According to the actual working conditions, the water wading area at the end of the main blade can be increased or decreased by adjusting the angle of the auxiliary blade, thereby adjusting the stirring effect near the pool wall.

[0026] The adjustment method of the mixer during operation in this utility model is as follows:

[0027] 1. When the process adjustment requires enhancing the bottom stirring effect, select a suitable adjusting body 61 and matching shim 62, so that the small end of the adjusting body 61 is located at the lower end of the connecting body, the angle between the working surface of the main blade 4 and the horizontal plane is α-β, the angle between the main blade 4 and the horizontal plane is reduced, the height of the working surface is increased, thereby increasing the bottom stirring effect.

[0028] 2. When the process adjustment requires reducing the bottom stirring effect, select a suitable adjusting body 61 and matching shim 62 so that the small end of the adjusting body 61 is located at the upper end of the connecting body, the angle between the working surface of the main blade and the horizontal plane is α+β, the angle between the main blade 4 and the horizontal plane increases, the height of the working surface is reduced, thereby reducing the bottom stirring effect.

[0029] 3. When it is necessary to enhance the mixing effect near the pool wall, loosen the fasteners between the adjusting hole 52 and the second mounting hole 42, allowing the auxiliary blades 5 to rotate a certain angle around the fixing hole 51 towards the pool wall. This increases the area of ​​the auxiliary blades 5 extending beyond the upper and lower parts of the main blades 4, thereby enhancing the mixing effect in the outer ring. Then, tighten the fasteners again. At this time, the auxiliary blades 5 on the main blades 4 perform work on the water, enhancing the mixing effect near the pool wall.

[0030] 4. When it is necessary to reduce the mixing effect near the pool wall, loosen the fasteners between the adjusting hole 52 and the second mounting hole 42, allowing the auxiliary blades 5 to rotate a certain angle away from the pool wall around the fixing hole 51. This reduces the area of ​​the auxiliary blades 5 extending beyond the upper and lower parts of the main blades 4, thereby weakening the mixing effect in the outer ring. Then, tighten the fasteners again. At this time, the auxiliary blades 5 on the main blades 4 perform work on the water, thus reducing the mixing effect near the pool wall.

[0031] like Figure 2 As shown, in a preferred embodiment, the hub 3 includes a body 31, a connecting body 32, and a connecting hole 33. The body 31 has a circular ring structure. A shaft hole is provided at the center of the body 31, and the body 31 is fitted onto the bottom end of the main shaft 2 through the shaft hole and fixedly connected to the main shaft 2. The connecting body 32 is disposed on the outer circumference of the body 31, and the connecting body 32 has a connecting hole 33. The body 31 of the hub 3 is connected to the bottom of the main shaft 2, ensuring that the hub 3 can rotate synchronously with the main shaft 2. Simultaneously, the main blade 4 is connected to the hub 3, thereby enabling the main blade 4 to rotate synchronously with the main shaft 2, ensuring the stirring effect inside the water tank.

[0032] As a preferred embodiment, the number of connecting bodies 32 is 2 to 3, and the connecting bodies 32 are inclinedly arranged on the outer circumference of the body 31; the angle between the connecting body 32 and the horizontal plane is α. The connecting bodies 32 are used to connect the main blade 4 and the hub 3. The evenly arranged connecting bodies 32 on the outer circumference of the body 31 can make the main blade 4 more stable when rotating; the inclined arrangement of the connecting bodies 32 can better adjust the rotation angle of the main blade 4 through the adjustment device 6.

[0033] like Figure 3As shown, in a preferred embodiment, the main blade 4 is provided with a first mounting hole 41, a second mounting hole 42, and a third mounting hole 43; the first mounting hole 41 and the second mounting hole 42 are located at the end of the main blade 4 away from the hub 3, with the first mounting hole 41 located directly below the second mounting hole 42; the third mounting hole 43 is located at the end of the main blade 4 close to the hub 3; the third mounting hole 43 is adapted to the connecting hole 33. The first mounting hole 41 and the second mounting hole 42 are used to connect the auxiliary blade 5 and adjust the tilt angle of the auxiliary blade; the third mounting hole 43 is used to fix the main blade 4 onto the connecting body 32 of the hub 3, and the rotating main blade 4 realizes the mixing and stirring of the agent and water.

[0034] like Figure 4 As shown, in a preferred embodiment, the auxiliary blade 5 is provided with a fixing hole 51 and an adjusting hole 52; the fixing hole 51 is located below the adjusting hole 2; the adjusting hole 52 is an arc-shaped hole, and the center of the center line of the adjusting hole 52 coincides with the center of the fixing hole 51; the fixing hole 51 and the adjusting hole 52 are respectively adapted to the first mounting hole 41 and the second mounting hole 42. The auxiliary blade 5 can rotate left and right around the fixing hole 51. After rotating to a set angle, it is fixed to the second mounting hole 42 on the main blade by fasteners passing through the adjusting hole 52. The rotating auxiliary blade mixes and stirs the agent and water at different positions on the outer end of the main blade.

[0035] When it is necessary to enhance the mixing effect near the pool wall, loosen the fasteners between the adjusting hole 52 and the second mounting hole 42, allowing the auxiliary blades 5 to rotate a certain angle around the fixing hole 51 towards the pool wall. This increases the area of ​​the auxiliary blades 5 extending beyond the upper and lower parts of the main blades 4, thereby enhancing the mixing effect in the outer ring. Then, tighten the fasteners again. At this time, each auxiliary blade 5 on the main blade 4 performs work on the water, enhancing the mixing effect near the pool wall.

[0036] When it is necessary to reduce the mixing effect near the pool wall, loosen the fasteners between the adjusting hole 52 and the second mounting hole 42, allowing the auxiliary blades 5 to rotate a certain angle away from the pool wall around the fixing hole 51. This reduces the area of ​​the auxiliary blades 5 extending beyond the upper and lower parts of the main blades 4, thus weakening the mixing effect in the outer ring. Then, tighten the fasteners again. At this time, the auxiliary blades 5 on the main blades 4 perform work on the water, reducing the mixing effect near the pool wall.

[0037] like Figure 5 , Figure 6As shown, in a preferred embodiment, the adjusting device 6 includes an adjusting body 61 and a shim 62. When the main blade 4 and the hub 3 are connected, the adjusting body 61, the main blade 4, and the shim 62 are sequentially arranged on the surface of the connecting body 32, and the adjusting body 61, the main blade 4, and the shim 62 are fixed to the connecting body 32 by fasteners. The adjusting device 6 adjusts the tilt angle of the main blade 4 through the adjusting body 61, thereby achieving the purpose of adjusting the stirring effect in the water tank.

[0038] As a preferred embodiment, the longitudinal section of both the adjusting body 61 and the shim 62 is triangular, and the included angle between the sides of both the adjusting body 61 and the shim 62 is β; 0≤β≤30°.

[0039] As a preferred example, the number of the adjusting bodies 61 is N, where N≥5; the side angle β of each adjusting body 61 is different; each adjusting body 61 corresponds to a shim 62 with the same side angle β.

[0040] Each adjusting body 61 with a different included angle in each adjusting device 6 corresponds to a shim 62 with the same included angle. Different angles of adjusting body 61 and corresponding shims 62 can be selected as needed to meet the requirements of different processes. During installation, the adjusting body 61 and the shim 62 are installed in opposite directions to ensure that the contact surface of the shim 62 in the rotation direction is perpendicular to the axis of the fastener, ensuring that the main blade 4 will not loosen.

[0041] like Figure 5 As shown, the small end of the adjusting body 61 is located at the upper end of the connecting body 32. At this time, the angle between the working surface of the main blade 4 and the horizontal plane is α+β. Since the angle between the working surfaces increases from α to α+β, the height of the working surface is reduced, thereby reducing the bottom stirring effect.

[0042] like Figure 6 As shown, the small end of the adjusting body 61 is located at the lower end of the connecting body 32. At this time, the angle between the working surface of the main blade 4 and the horizontal plane is α-β. Since the angle between the working surfaces decreases from α to α-β, the height of the working surface is increased, thereby increasing the bottom stirring effect.
