Description

Technical Field

[0001] The utility model relates to the technical field of metering equipment, in particular to a metering device for feeding liquid materials. Background Art

[0002] In the fields of industry, food processing or commercial circulation, it is often necessary to accurately measure the continuously transported liquid materials. The liquid transportation process is a continuous process, and the liquid weight needs to be measured in this continuous process. The general method is to first use a flow meter to measure the volume of the flowing liquid, and then convert the volume into the weight of the liquid.

[0003] In food production and processing, liquid raw materials are first injected into a metering barrel through a feed pipe. When the liquid raw materials in the metering barrel reach a specified amount, the liquid raw materials can be discharged into the food processing equipment.

[0004] When loading materials, the existing metering equipment directly fixes the feeding tube on the top of the metering cylinder. During the filling process, the liquid material discharged from the feeding tube falls directly into the metering cylinder. Due to the large height difference, the liquid will directly splash on the inner wall of the metering cylinder, resulting in large metering errors and affecting the metering detection accuracy.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0020] like Figure 1 、 Figure 2 The figure shows a structural diagram of a metering device for feeding liquid materials provided by an embodiment of the present invention, comprising a metering cylinder 1, wherein support legs 2 are fixedly installed around the bottom wall of the metering cylinder 1, a guide pipe 3 is provided at the bottom end of the metering cylinder 1, a control valve 4 is provided on the surface of the guide pipe 3, a feeding pipe 5 is provided in the inner cavity of the metering cylinder 1, a material guide pipe 6 is connected to the side wall of the feeding pipe 5, and the material guide pipe 6 is connected to an external pump. A positioning mechanism 7 that cooperates with the feeding pipe 5 is provided at the top of the metering cylinder 1, and the positioning mechanism 7 includes a bearing plate 71, a support assembly 72 and a lifting assembly 73. The support assembly 72 is located on the side wall of the bearing plate 71 and is connected to the top of the metering cylinder 1, and the lifting assembly 73 is located on the surface of the bearing plate 71 and is connected to the feeding pipe 5. A positioning hole 711 is opened on the surface of the bearing plate 71, and the material guide pipe 6 passes through the positioning hole 711.

[0021] When the liquid needs to be measured, the supporting plate 71 is first installed on the top of the metering cylinder 1 through the supporting assembly 72, and the lifting assembly 73 controls the feeding tube 5 to move vertically downward in the inner cavity of the metering cylinder 1. When the feeding tube 5 moves to the bottom of the metering cylinder 1, the guide tube 6 cooperates with the feeding tube 5 to transport the liquid to be measured to the inner cavity of the metering cylinder 1. During the infusion process, since the distance between the discharge port of the feeding tube 5 and the bottom wall of the metering cylinder 1 is small, liquid splashing can be effectively avoided. As the liquid level gradually rises, the lifting assembly 73 controls the feeding tube 5 to move upward synchronously in the inner cavity of the metering cylinder 1, which can effectively improve the measurement accuracy.

[0022] like Figure 1 、 Figure 2 、 Figure 3As shown, as a preferred embodiment of the present invention, the support assembly 72 includes support rods 721 rotatably installed around the side walls of the carrier plate 71, and the support rod 721 is rotatably installed at one end away from the carrier plate 71 with a buckle 722 that cooperates with the top wall of the metering cylinder 1. When in use, the buckle 722 is inserted into the top wall of the metering cylinder 1, and the buckle 722 cooperates with the support rod 721 to stably install the carrier plate 71 above the metering cylinder 1.

[0023] like Figure 1 、 Figure 2 、 Figure 3 As shown, as a preferred embodiment of the present invention, the lifting assembly 73 includes two sets of relatively distributed vertical plates 731 fixedly mounted on the surface of the supporting plate 71, and the two sets of vertical plates 731 are jointly rotatably mounted with a rotating rod 732, and a winding wheel 733 is fixedly mounted on the surface of the rotating rod 732. A traction rope 735 is wound on the surface of the winding wheel 733. A through hole 734 is opened on the surface of the supporting plate 71, and the traction rope 735 away from the winding wheel 733 passes through the through hole 734 and extends to the bottom of the supporting plate 71 and is fixedly connected to a suspension block 736. The feeding pipe 5 is fixedly mounted on the bottom end of the suspension block 736, and one end of the rotating rod 732 extends to the outside of the vertical plate 731 and is connected to a motor 737. When in use, the motor 737 rotates the rotating rod 732 to drive the winding wheel 733 to rotate. The winding wheel 733 cooperates with the traction rope 735 to drive the suspension block 736 to move vertically in the inner cavity of the metering cylinder 1, thereby conveniently adjusting the height of the feeding pipe 5.

[0024] like Figure 1 、 Figure 2 As shown in FIG. 7 , as a preferred embodiment of the present invention, a protective roller 8 that cooperates with the material guide tube 6 is rotatably installed in the positioning hole 711 .

[0025] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, the suspension block 736 is made of magnetic material, and a magnetic sheet 9 that cooperates with the suspension block 736 is fixedly mounted on the bottom wall of the supporting plate 71 .

[0026] The working principle of the present invention is: when it is necessary to measure the liquid, the supporting plate 71 is first installed on the top of the metering cylinder 1 through the supporting assembly 72, and the lifting assembly 73 controls the feeding tube 5 to move vertically downward in the inner cavity of the metering cylinder 1. When the feeding tube 5 moves to the bottom of the metering cylinder 1, the guiding tube 6 cooperates with the feeding tube 5 to transport the liquid to be measured to the inner cavity of the metering cylinder 1. During the infusion process, since the distance between the discharge port of the feeding tube 5 and the bottom wall of the metering cylinder 1 is small, liquid splashing can be effectively avoided. As the liquid level gradually rises, the lifting assembly 73 controls the feeding tube 5 to move upward synchronously in the inner cavity of the metering cylinder 1, which can effectively improve the measurement accuracy.

[0027] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
