Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment agents, and particularly relates to a feeding device for metal surface treatment agents. Background Art

[0002] Coating paint or powder is an anti-corrosion method widely used in metal surface treatment. Metal surface treatment agents are an essential pre-treatment process before coating. Its function is to enable metal workpieces to have good adhesion to the coating, so that the two can adhere more firmly together, thereby preventing the coating from falling off. Metal surface treatment agents need to mix raw materials with water and stir them together. The mixing bucket is placed upright at a high place so that the stirred materials in the mixing bucket can be circulated and stirred (flow out from the bottom of the mixing bucket and enter through the opening of the mixing bucket by a pump). Powdered raw materials need to be lifted onto a high step and then the raw material bags need to be lifted and dumped, which is time-consuming and laborious and is very easy to scatter all over the place. Summary of the Invention

[0003] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a feeding device for metal surface treatment agents.

[0004] The utility model provides a feeding device for metal surface treatment agents, which includes a frame 1. A hopper 2 is arranged in the middle of the frame 1. A conveying pipe 3 is obliquely arranged on the right side of the hopper 2. Seals are arranged at both the upper and lower ends of the conveying pipe 3. A screw conveyor 4 for upwardly conveying powder and driven by a motor 7 is rotatably and coaxially arranged in the conveying pipe 3. A connecting pipe 5 is connected between the discharge port of the hopper 2 and the conveying pipe 3. The upper end of the conveying pipe 4 is downwardly connected with a discharge pipe 6.

[0005] Further, a connecting plate 9 is obliquely arranged at the right end of the hopper 2. The motor 7 is arranged on the connecting plate 9. Hoop clamps 10 for holding the conveying pipe 3 are arranged on both the upper and lower sides at the right end of the connecting plate 9.

[0006] Further, the inclination angle of the conveying pipe 3 is the same as that of the right inclined surface of the hopper 2.

[0007] Further, a rotating shaft 11 that extends into the connecting pipe 5 and is driven by the motor 7 is rotatably arranged at the lower seal. Breaking blocks are circumferentially distributed at the upper end of the rotating shaft 11.

[0008] Further, belt pulleys are keyed on the screw conveyor 4, the output shaft of the motor 7, and the rotating shaft 11. The belt pulleys are connected by a belt 8.

[0009] Further, a counterweight block 12 is arranged at the bottom of the left end of the frame 1.

[0010] The advantages of the present utility model are as follows: The powder enters the bottom of the conveying pipe through the hopper and the connecting pipe, and is then conveyed to the high-position discharge pipe by the auger driven by the motor and falls into the stirring barrel with an upward opening, which saves time and effort; the conveying pipe and the motor are fixed by the connecting plate to ensure that the inclination angles of the conveying pipe and the motor are the same and facilitate installation; the inclination angle of the conveying pipe is the same as that of the right inclined surface of the hopper, so that the conveying pipe can be attached to the connecting plate, and the connecting plate is attached to the hopper, thereby improving the stability of the conveying pipe; the auger and the rotating shaft are driven by the motor at the same time. The auger can continuously convey the powder upward, and the rotating shaft periodically breaks the powder agglomerates through the crushing blocks and prevents the inlet of the connecting pipe from being blocked; since the device will tilt to the right under the action of the conveying pipe and the auger, a counterweight is used for stabilization.

[0016] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0017] Referring to Figures 1 to 5 , the present utility model provides a feeding device for a metal surface treatment agent, which includes a frame 1 composed of angle irons around. A hopper 2 is arranged in the middle of the frame 1. The hopper is a downward pyramid shape. A conveying pipe 3 is inclinedly arranged on the right side of the hopper 2. Seals are arranged at both the upper and lower ends of the conveying pipe 3. An auger 4 for upwardly conveying powder and driven by a motor 7 is rotatably and coaxially arranged in the conveying pipe 3. A connecting pipe 5 is connected between the discharge port of the hopper 2 and the conveying pipe 3. The upper end of the conveying pipe 3 is downwardly connected to a discharge pipe 6. Pour the powder raw material of the metal surface treatment agent into the hopper. The powder enters the bottom of the conveying pipe through the hopper and the connecting pipe, and is then conveyed to the high-position discharge pipe by the auger driven by the motor, and then enters the stirring barrel with an upward opening from the discharge pipe.

[0018] Referring to Figure 2 , Figure 3, a connecting plate 9 is obliquely arranged at the right end of the hopper 2, the motor 7 is arranged on the connecting plate 9, and hoops 10 for holding the conveying pipe 3 are arranged on both the upper and lower sides at the right end of the connecting plate 9. The conveying pipe is fixed to the connecting plate by welding. The conveying pipe and the motor are fixed through the connecting plate, ensuring that the inclination angles of the conveying pipe and the motor are the same and facilitating installation.

[0019] The inclination angle of the conveying pipe 3 is the same as that of the right inclined surface of the hopper 2. The above setting can make the conveying pipe lean against the connecting plate, and the connecting plate lean against the hopper, thereby improving the stability of the conveying pipe.

[0020] A rotating shaft 11 that extends into the connecting pipe 5 and is driven by the motor 7 is rotatably arranged at the lower side cover. Crushing blocks are circumferentially distributed at the upper end of the rotating shaft 11. By driving the auger and the rotating shaft simultaneously with the motor, the auger can continuously convey the powder upward, and the rotating shaft periodically crushes the powder lumps through the crushing blocks and prevents the inlet of the connecting pipe from being blocked.

[0021] Pulley wheels are keyed on the output shafts of the auger 4, the motor 7, and the rotating shaft 11, and the pulley wheels are connected by a belt 8.

[0022] A counterweight 12 is arranged at the bottom of the left end of the frame 1. Since the device will tilt to the right under the action of the conveying pipe and the auger, it is stabilized by the counterweight.

[0023] For the feeding device of the metal surface treatment agent of the present utility model, the powder enters the bottom of the conveying pipe through the hopper and the connecting pipe, and is then conveyed to the high outlet pipe by the auger driven by the motor and falls into the stirring barrel with an upward opening, saving time and effort.

[0024] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
