Abstract

Technical Field
[0001] This utility model relates to the field of filling machine technology, and in particular to a material anti-sedimentation circulating stirring structure and a liquid filling machine. Background Technology
[0002] In the production of liquids such as beverages, shampoos, automotive engine antifreeze, and transmission fluid, filling equipment is used to fill them into bottles before they are sold. In order to prevent the liquid from settling, a stirring rod is usually installed in the mixing tank to agitate the liquid.
[0003] A search revealed a liquid mixing and filling machine (publication number: CN104071730A) which includes a housing, a liquid mixing tank, a control valve, a drive motor, a stirring mechanism, a mounting frame, a filling frame, a rotating shaft, a pressing mechanism, a filling plate, a spring, and a baffle. Several liquid mixing tanks are located at the upper end of the housing, and control valves are installed at the outlets of the liquid mixing tanks. A drive motor is installed in the middle of the upper end of the housing, and the rotating shaft of the drive motor is connected to the shaft of the stirring mechanism via a bushing. A mounting frame is installed at the left end of the housing, and the rotating shaft passes through the mounting frame. The bottom of the mounting frame is installed in the mounting hole in the middle of the filling frame. The baffle is slidably connected to the right end of the housing. The pressing mechanism is installed at the bottom left side of the housing, and a filling plate is located below the pressing mechanism. The filling plate is connected to the bottom of the housing via a spring, and several filling ports are provided on the filling plate. The filling ports are connected to the interior of the housing via pipes and valves.
[0004] In existing technologies, liquids are mainly stirred by a motor-driven stirring rod. To avoid interference from the stirring rod's movement, the stirring rod is usually placed at a distance from the bottom of the tank. As the stirring rod stirs the liquid, turbulence is formed, and the flow rate of the liquid at the bottom is relatively slow, which easily leads to sedimentation and affects the quality of the liquid after filling. There is room for optimization.
[0005] Therefore, we propose a material anti-sedimentation circulating stirring structure and a liquid filling machine. Utility Model Content
[0006] The present invention mainly addresses the technical problem of sedimentation easily forming in the bottom layer, and provides a material anti-sedimentation circulating stirring structure and a liquid filling machine.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a material anti-sedimentation circulating stirring structure, comprising:
[0008] The main shaft has several stirring rods fixedly installed on its side wall;
[0009] A jetting structure, located at the lower end of the main shaft, is used to draw and spray liquid. The jetting structure includes a volute, an impeller, a jetting pipe, and a side suction pipe. The volute is fixedly located below the main shaft, and a window is provided on the top of the volute. Several side suction pipes extending into the window are fixedly installed on the top of the volute. Several jetting pipes are fixedly installed on the side wall of the volute. The impeller is rotatably connected to the volute and fixedly connected to the end of the main shaft. The main shaft can drive the impeller to rotate and draw liquid from the window into the volute.
[0010] In a preferred embodiment of this invention, the volute is formed into a sealed cylinder, and the window is located on the upper surface of the volute and is circular.
[0011] In a preferred embodiment of this utility model, the impeller includes a base and several blades, the blades are fixedly connected to the base, and the base is rotatably connected to the volute.
[0012] In a preferred embodiment of this utility model, the side suction tube is an L-shaped tube, with one end of the side suction tube located above the window and the other end of the side suction tube extending to one side of the volute.
[0013] In a preferred embodiment of this invention, the injection pipe is a horizontally curved pipe that extends through the side wall of the volute to the inner wall of the volute, and the injection pipe does not interfere with the impeller.
[0014] In a preferred embodiment of this utility model, the spray structure further includes a baffle and a cover. The baffle is fixedly installed on the side wall of the side suction pipe, and the baffle faces the port of the spray pipe. The cover is fixedly connected to the top of the volute and faces the window. The side suction pipe is fixedly installed on the upper surface of the cover.

[0016] Beneficial effects
[0017] This utility model provides a material anti-sedimentation circulating stirring structure and a liquid filling machine. It has the following beneficial effects:
[0018] 1. This material anti-sedimentation circulating stirring structure and liquid filling machine uses a motor to drive the main shaft to rotate. The main shaft drives multiple E-shaped stirring rods to agitate the material inside the main shaft. At the same time, the main shaft also drives the impeller to perform circumferential motion. The rotation of the impeller squeezes the liquid in the volute, causing the liquid to be sprayed out from various spray pipes, promoting the flow of the bottom liquid and inhibiting sedimentation. Simultaneously, the rotation of the impeller also creates a vortex above the volute, drawing liquid in through the window, achieving liquid circulation and stirring. The liquid flow speed at the window is fast. Under the Venturi effect, the side suction pipe draws liquid from one side of the volute into the window, further improving the fluidity of the bottom liquid. By using liquid extraction and spraying, the probability of liquid sedimentation during the filling process is greatly reduced.
[0019] 2. This material anti-sedimentation circulating stirring structure and liquid filling machine sprays liquid out through a spray pipe and impacts an arc-shaped baffle. The baffle guides the liquid sprayed from the spray pipe and shears the liquid pushed by the stirring rod, resulting in better stirring of the liquid at the bottom and making it less prone to sedimentation. Secondly, by setting a cover, the liquid at the center of the vortex is guided by the funnel-shaped cover, which facilitates the liquid being sucked into the volute by the impeller. The overall structure is simple and does not require multiple power sources to drive it. Attached Figure Description

[0026] A material anti-sedimentation circulating stirring structure and a liquid filling machine, such as Figure 1 As shown, it includes:
[0027] Main shaft 10, with several stirring rods 11 fixedly installed on the side wall of main shaft 10;
[0028] like Figure 2 and Figure 3As shown, the jetting structure, located at the lower end of the main shaft 10, is used to draw and spray liquid. The jetting structure includes a volute 20, an impeller 21, a jetting pipe 22, and side suction pipes 23. The volute 20 is fixedly located below the main shaft 10, and a window is provided at the top of the volute 20. Several side suction pipes 23 extending into the window are fixedly installed at the top of the volute 20. Several jetting pipes 22 are fixedly installed on the side walls of the volute 20. The impeller 21 is rotatably connected to the volute 20 and fixedly connected to the end of the main shaft 10. The main shaft 10 can drive the impeller 21 to rotate, drawing liquid from the window into the volute. Inside the volute 20, the volute 20 forms a sealed cylinder. The window is opened on the upper end face of the volute 20 and is circular. The impeller 21 includes a base and several blades. The blades are fixedly connected to the base, and the base is rotatably connected to the volute 20. The side suction pipe 23 is an L-shaped pipe. One end of the side suction pipe 23 is located above the window, and the other end of the side suction pipe 23 extends to one side of the volute 20. The jet pipe 22 is a horizontally curved pipe that penetrates the side wall of the volute 20 and extends to the inner wall of the volute 20. The jet pipe 22 does not interfere with the impeller 21.
[0029] In this scheme, the main shaft 10 is driven to rotate by a motor. The main shaft 10 drives multiple E-shaped stirring rods 11 to agitate the material inside the main shaft 10. At the same time, the main shaft 10 also drives the impeller 21 to perform circular motion. The rotation of the impeller 21 squeezes the liquid inside the volute 20, causing the liquid to be sprayed out from each spray pipe 22, promoting the flow of the bottom liquid and inhibiting the formation of sediment. At the same time, the rotation of the impeller 21 also creates a vortex above the volute 20, and the liquid is drawn in through the window, realizing the circulation and agitation of the liquid. The liquid flow speed at the window is fast. Under the Venturi effect, the side suction pipe 23 will draw the liquid on one side of the volute 20 into the window, further improving the fluidity of the bottom liquid and greatly reducing the probability of liquid sedimentation during the filling process.
[0030] like Figure 3 As shown, the spray structure also includes a baffle 24 and a cover 25. The baffle 24 is fixedly installed on the side wall of the side suction pipe 23. The baffle 24 is directly opposite the port of the spray pipe 22. The cover 25 is fixedly connected to the top of the volute 20 and faces the window. The side suction pipe 23 is fixedly installed on the upper surface of the cover 25.
[0031] As a supplementary explanation of the above scheme, the liquid is sprayed out through the injection pipe 22 and impacts the arc-shaped baffle 24. The baffle 24 guides the liquid sprayed out by the injection pipe 22 and shears the liquid pushed by the stirring rod 11, so that the bottom liquid has a better stirring effect and is less likely to settle. Secondly, by setting the cover 25, the liquid in the center of the vortex is guided by the trumpet-shaped cover 25, which facilitates the liquid to be sucked into the volute 20 by the impeller 21. The overall structure is simple and does not require multiple power sources to drive it.
[0032] like Figure 4 and Figure 5As shown, a liquid filling machine includes a liquid preparation tank 30, a metering valve 31 fixedly installed on the outside of the liquid preparation tank 30, and a material anti-sedimentation circulation stirring structure provided inside the liquid preparation tank 30. The main shaft 10 is rotatably connected to the liquid preparation tank 30, the volute 20 is fixedly connected to the bottom of the liquid preparation tank 30, and a motor-driven main shaft 10 is fixedly installed on the top of the liquid preparation tank 30. The main shaft 10 is fixedly connected to the output shaft of the motor. A controller should be provided on one side of the main shaft 10 to control the motor and the metering valve 31. A conveying pump is also provided inside the main shaft 10. The metering valve 31 is connected to the discharge port of the conveying pump through a pipe. Quantitative discharge and filling are achieved through the metering valve 31.
[0033] By setting up the above structure, the liquid at the bottom of the liquid preparation tank 30 has better fluidity and is less prone to sedimentation during the filling process, thereby ensuring the uniformity of the liquid throughout the filling process.
[0034] The working principle of this invention is as follows: A motor drives the main shaft 10 to rotate, which in turn drives multiple E-shaped stirring rods 11 to agitate the material inside the main shaft 10. Simultaneously, the main shaft 10 drives the impeller 21 to rotate in a circular motion. The rotation of the impeller 21 compresses the liquid inside the volute 20, causing it to be ejected from various spray pipes 22, promoting the flow of the bottom liquid and inhibiting sedimentation. Furthermore, the rotation of the impeller 21 creates a vortex above the volute 20, drawing liquid in through the window, thus achieving liquid circulation and agitation. The liquid flow at the window... The speed is fast. Under the Venturi effect, the side suction pipe 23 will suck the liquid on one side of the volute 20 into the window, further improving the fluidity of the bottom liquid. The liquid is sprayed out through the jet pipe 22 and impacts the arc-shaped baffle 24. The baffle 24 guides the liquid sprayed out by the jet pipe 22 and shears the liquid pushed by the stirring rod 11, so that the bottom liquid is better stirred and less prone to sedimentation. Secondly, by setting the cover 25, the liquid in the center of the vortex is guided by the trumpet-shaped cover 25, which makes it easier for the liquid to be sucked into the volute 20 by the impeller 21.
[0035] The well-mixed liquid is pumped to metering valve 31 and then piped into a container for filling.
