[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5 As shown, a dosing device for industrial wastewater treatment includes a mixing tank 1 and a mixing barrel 3. A mounting base 2 is fixedly connected to the upper side of the mixing tank 1 near the left side. A barrel cover 4 overlaps the upper side of the mixing barrel 3. A stirring mechanism 5 is fixedly sleeved on the inner side of the mixing barrel 3 near the upper side. A power mechanism 6 is movably installed in the middle of the upper side of the barrel cover 4. A fixing mechanism 7 is fixedly connected to the upper side of both the mounting base 2 and the barrel cover 4 near the edge.

[0028] The mixing mechanism 5 includes a fixed frame 51. The outer side of the fixed frame 51 is fixedly sleeved on the inner side of the mixing tank 3 near the upper side. The outer side of the upper boss of the fixed frame 51 is movably sleeved with a mounting frame 56. The inner side of the mounting frame 56 is rotatably connected to a mixing frame 52. The outer side of the mixing frame 52 near the upper side is movably sleeved with a transmission sleeve 53. The outer side of the transmission sleeve 53 is movably sleeved with a rotating seat 54. The outer side of the rotating seat 54 is movably installed with the power mechanism 6.

[0029] It should be noted that the mixing tank 3 is equipped with a first valve on its lower side to control the flow rate and amount of the medicine liquid in the mixing tank 3 into the mixing box 1. The tank cover 4 is equipped with several medicine inlet pipes and a second valve to control the amount of medicine entering the mixing tank 3. The fixing frame 51 is used to restrict the mounting frame 56 so that the fixing frame 51 and the mounting frame 56 cannot rotate relative to each other. There is a bolt between the transmission sleeve 53 and the rotating seat 54. Removing the bolt allows the transmission sleeve 53 and the rotating seat 54 to move up and down relative to each other. Reinstalling the bolt fixes them together. The power mechanism 6 contains a motor to drive the rotating seat 54 to rotate, which in turn drives the stirring frame 52 to rotate through the transmission sleeve 53.

[0030] like Figure 3 As shown, the outer side of the fixing frame 51 has several annularly distributed drainage holes 55.

[0031] It should be noted that the drain hole 55 is used to prevent the fixing frame 51 from separating the inside of the mixing tank 3, so that when the mixing tank 3 is cleaned, water stains inside the mixing tank 3 can flow out through the drain hole 55 and are not blocked by the fixing frame 51.

[0032] like Figure 4As shown, the fixing mechanism 7 includes a fixing ring 71. The side of the fixing ring 71 away from the fixing frame 51 is fixedly connected to the upper side of the mounting base 2 and the barrel cover 4 near the edge via an annular plate. Several annularly distributed balls 72 are movably sleeved on the inner side of the side wall of the fixing ring 71. A retaining ring 73 is rotatably connected to the inner side of the fixing ring 71, and the retaining ring 73 is located on the side of the balls 72 away from the fixing frame 51. The side of the balls 72 away from the retaining ring 73 is movably sleeved in the grooves opened on the outer side of the mixing barrel 3 near the upper and lower sides. Several annularly distributed ball grooves 74 are opened on the inner side of the retaining ring 73.

[0033] It should be noted that when the ball groove 74 and the ball 72 are misaligned, the retaining ring 73 fixes the ball 72, preventing the ball 72 from moving, thus fixing the ball 72 to the mixing tank 3. Rotating the retaining ring 73 aligns the ball groove 74 with the ball 72, allowing the ball 72 to move and thus releasing the ball 72 from fixing the mixing tank 3.

[0034] like Figure 4 As shown, a rotating ring 76 is rotatably connected to the outer side of the fixed ring 71. Several annularly distributed limiting grooves 75 are provided on the outer side of the fixed ring 71. Several annularly distributed round shafts are fixedly connected to the outer side of the retaining ring 73. The inner side of the rotating ring 76 is fixedly connected to the side of the round shaft away from the mixing tank 3, and the round shaft is movably sleeved on the inner side of the limiting groove 75.

[0035] It should be noted that rotating the rotating ring 76 causes the retaining ring 73 to rotate. The limiting groove 75 is used to limit the rotation amplitude of the rotating ring 76, so that the ball groove 74 at both ends of the limiting groove 75 can be aligned with or offset from the ball 72.

[0036] like Figure 5 As shown, two insert rods 77 distributed front to back are movably sleeved on the inner side of the outer boss of the rotating ring 76. The outer side of the insert rod 77 near the mixing tank 3 is movably sleeved in the insertion hole opened on the outer side of the fixed ring 71, and the right sides of the two insert rods 77 are fixedly connected together by a thin plate.

[0037] It should be noted that when the insert rod 77 is inserted into the socket, the rotating ring 76 and the fixed ring 71 are fixed together, so that the rotating ring 76 cannot rotate.

[0038] like Figure 5 As shown, springs 78 are movably sleeved on the outer sides of both insert rods 77, and springs 78 are located inside the outer boss of the rotating ring 76. Circular plates 79 are fixedly connected to the outer sides of both insert rods 77, and circular plates 79 are located on the side of springs 78 closer to the mixing tank 3.

[0039] It should be noted that the spring 78 pushes the circular plate 79, making the insertion rod 77 more stable when inserted into the insertion hole. When the rotating ring 76 needs to be rotated, the insertion rod 77 needs to be pulled first to make the rotating ring 76 rotate.

[0040] like Figure 4 As shown, several annularly distributed positioning shafts 710 are fixedly connected to the upper side of the fixing ring 71, and the outer flange of the mixing tank 3 near the upper and lower sides is movably sleeved on the inner side of the positioning shafts 710.

[0041] It should be noted that the positioning shaft 710 is used to limit the mixing tank 3 so that when the mixing tank 3 is fitted into the inner side of the fixing ring 71, the ball bearing 72 can be aligned with the groove on the outer side of the mixing tank 3.

[0042] The working principle of this utility model is as follows: First, the fixing frame 51 restricts the mounting frame 56, preventing relative rotation between the fixing frame 51 and the mounting frame 56. Bolts are provided between the transmission sleeve 53 and the rotating seat 54. Removing the bolts allows the transmission sleeve 53 and the rotating seat 54 to move up and down relative to each other. Reinstalling the bolts fixes them together. The power mechanism 6 contains a motor to drive the rotating seat 54 to rotate, which in turn drives the mixing frame 52 to rotate via the transmission sleeve 53. By removing the lid 4 from the mixing tank 3, the transmission sleeve 53 and the mixing frame 52 are directly separated, avoiding the problem of difficulty in removal due to their connection. During installation, the lid 4 is directly installed, and the transmission sleeve 53 and the rotating seat 54 are then fixed with bolts. Installation is convenient and operation is easy. The split design makes the lid 4 easy to install and maintain. In the protective operation, when the ball groove 74 and the ball 72 are misaligned, the retaining ring 73 fixes the ball 72, preventing it from moving and thus fixing the ball 72 to the mixing tank 3. Rotating the retaining ring 73 aligns the ball groove 74 with the ball 72, allowing the ball 72 to move and release its fixation to the mixing tank 3. Rotating the rotating ring 76 causes the retaining ring 73 to rotate. The limiting groove 75 limits the rotation amplitude of the rotating ring 76, allowing the ball groove 74 to be aligned with or misaligned with the ball 72 at both ends of the limiting groove 75. By rotating the retaining ring 73, the mixing tank 3 and the mounting base 2 can be quickly connected and separated, making installation convenient and disassembly quick, avoiding the cumbersome use of screws and other methods. The use of the ball 72 for fixing also simplifies the overall structure.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
