[0002] A mixer is a machine with a bladed shaft rotating in a cylinder or tank, mixing and stirring a variety of raw materials to make a mixture or a suitable consistency. Mixers are widely used in water supply and drainage projects, dissolving various water treatment agents or quickly mixing and reacting raw water and coagulants. In the production of our company's products, some raw materials are added in a special way, which requires dripping in a closed container with high-speed stirring. At the same time, the viscosity of such raw materials is also relatively large, and the dripping amount and time need to be precisely controlled. On the other hand, the viscosity of the raw materials often varies with temperature, so it is also difficult to measure how much raw material is dripped in. Utility Model Content

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0021] An embodiment of the present application provides a dripping device for a blender, which can realize the addition of additives during processing through a feeding component, thereby avoiding the spillage of rapidly rotating raw materials during processing, reducing the air release time, and avoiding quality problems caused by external environmental interference.

[0022] The dripping device for the mixer is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0023] The present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1-5 In the embodiment, a dripping device for a mixer is provided, comprising: a base 1, a tank body 11 is arranged inside the base 1, a sealing cover 12 is fixedly installed on the top of the tank body 11, a stirring rod body 13 is fixedly installed on the sealing cover 12, a feeding cylinder 14 is arranged on the top of the sealing cover 12, a piston rod 15 is slidably connected inside the feeding cylinder 14, a feeding assembly is arranged on the feeding cylinder 14, and is used to add additives into the tank body 11, and the feeding assembly comprises: a valve seat 2, a valve core 21, an injection cylinder 22, and a push rod 23.

[0024] In some embodiments, a valve seat 2 is fixedly connected to the inner wall of the feeding barrel 14, a valve core 21 is provided inside the valve seat 2, an injection barrel 22 is threadedly connected to the top end of the feeding barrel 14, a top opening rod 23 is fixedly connected to the bottom end of the injection barrel 22, a guide frame 24 is fixedly connected to the inner wall of the feeding barrel 14, a connecting rod 25 is slidably connected inside the guide frame 24, a spring 26 is sleeved on the outside of the connecting rod 25, and the top end of the connecting rod 25 is connected to the valve core 21, an insertion hole 27 is opened at the top of the valve core 21, a diverter chamber 28 is opened inside the valve core 21, the top of the diverter chamber 28 is communicated with the insertion hole 27, and a plurality of feed holes 29 are respectively opened on the sides of the diverter chamber 28, and the feed holes 29 are all arranged to be inclined downward.

[0025] When it is necessary to add additives, the additives are sucked with the syringe 22. After the required amount is sucked, the syringe 22 is screwed onto the filling barrel 14. When screwing, the push rod 23 is aligned with the insertion hole 27. As the push rod 23 is continuously lifted, the valve core 21 is pressed downward. As the valve core 21 pushes the connecting rod 25 to continuously move downward, the valve core 21 moves along the inside of the guide frame 24 to play a guiding role. During the downward movement, the valve core 21 squeezes the spring 26, and the spring 26 is squeezed and contracts to store energy. When the push rod 23 is inserted to the bottom, the valve core 21 moves a short distance from the inside of the valve seat 2, so that the feed hole 29 is connected to the inside of the tank body 11. At this time, the piston rod 15 is pushed to inject the additive in the syringe 22. The additive flows out from the push rod 23 and flows into the insertion hole 27, then flows into the diverter chamber 28, and flows to each feed hole 29 through the diverter chamber 28, and flows into the inside of the tank body 11 through the feed hole 29 to complete the addition. After the addition is completed, the injection cylinder 22 is removed from the feeding cylinder 14, and the injection cylinder 22 is rotated to make the injection cylinder 22 screwed out from the inside, while driving the push rod 23 to move upward. During the movement, the valve core 21 is pushed upward by the spring 26 until the valve core 21 completely enters the valve seat 2. Under the action of the elastic force of the spring 26, the valve core 21 is tightly fitted with the valve seat 2, so that the feed hole 29 is blocked by the valve seat 2, thereby sealing and isolating the external air, so as to add additives to the inside during processing.

[0026] In some embodiments, a volume control component is provided on the sealing cover 12, and the volume control component includes: a base 3 fixedly connected to the top of the sealing cover 12, a gantry 31 fixedly connected to the top of the base 3, a threaded screw 32 arranged between the gantry 31 and the base 3, a servo motor 33 fixedly installed inside the base 3, a driving shaft at the top of the servo motor 33 is connected to the threaded screw 32, a threaded block 34 threadedly connected to the outside of the threaded screw 32, a pressure plate 35 fixedly connected to one side of the threaded block 34, two symmetrically arranged guide rods 36 are fixedly connected between the gantry 31 and the base, a guide hole for use with the two guide rods 36 is provided on the threaded block 34, the threaded block 34 is slidably connected to the outside of the two guide rods 36, a positioning rod 37 is fixedly connected to the top of the piston rod 15, and a U-shaped groove 38 for use with the positioning rod 37 is provided at the end of the pressure plate 35 away from the threaded block 34.

[0027] When it is necessary to control the amount and time of additive dripping, the servo motor 33 is used to drive the threaded screw 32 to rotate, and the threaded screw 32 rotates and screws into the threaded block 34. Due to the restriction of the two guide rods 36, the threaded block 34 can only move along the direction of the guide rod 36, thereby driving the threaded block 34 to move downward, and the threaded block 34 drives the pressure plate 35 to move downward. When the syringe 22 is connected, the U-shaped groove 38 at one end of the pressure plate 35 is stuck on the positioning rod 37. Therefore, the downward movement of the pressure plate 35 will push the piston rod 15 to move downward, thereby causing the additive to flow out of the syringe 22 for feeding. The servo motor 33 can be edited to control the rotation direction, rotation speed, and number of rotations through the servo motor 33, thereby meeting the needs of mass production of the same material. When the syringe 22 is removed, the servo motor 33 rotates in the opposite direction to separate the pressure plate 35 from the positioning rod 37.
