Description

Technical Field

[0001] This utility model relates to the field of metering equipment technology, specifically to a liquid material metering device capable of cleaning the inner wall of a metering tank. Background Technology

[0002] Metrology is the use of technical and legal means to achieve uniformity of units and accurate and reliable measurement values. In the metrology process, the measuring tools and instruments used are considered to be standard. They are used to calibrate and verify the measuring tools and instruments under test in order to measure and ensure the reliability of the measurement results obtained when using the measuring tools and instruments under test.

[0003] The utility model patent with authorization announcement number CN 209541839 U discloses a liquid metering device. Through the use of a liquid storage rack and a metering mechanism, the liquid can be metered and dispensed, avoiding excessive dispensing that could lead to waste or harm. The use of a metering adjustment mechanism increases the adjustability of the metering mechanism, making the liquid metering more accurate.

[0004] However, the aforementioned liquid material metering device has a complex structure, and the inner wall of the liquid storage cone is easily contaminated with residual liquid material, which may change the concentration of the liquid material. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes a liquid material metering device that can clean the inner wall of the metering tank, thereby solving the problem of liquid material residue in the storage tank and thus changing the concentration of the liquid material.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A liquid material metering device capable of cleaning the inner wall of a metering tank includes a metering tank, a rinsing assembly on the metering tank, and a volume control assembly on the metering tank.

[0008] The rinsing assembly includes a fixed tube, a connecting tube fixedly connected to the fixed tube, a connecting ring rotatably connected inside the fixed tube, a rotating tube fixedly connected to the inner side of the connecting ring, and a nozzle fixedly connected to the rotating tube.

[0009] Preferably, the inner bottom wall of the metering barrel is designed to be inclined and its bottom is fixedly connected to an outlet pipe. The front side of the metering barrel is provided with a visual window, and the visual window is provided with scale.

[0010] Preferably, the fixing pipe is fixedly connected to the top wall of the metering barrel, and the connecting pipe is a flexible hose designed and located on the outside of the metering barrel.

[0011] Preferably, one side of the fixed tube extends into the interior of the metering barrel, and a connecting groove is provided inside the fixed tube, with the connecting ring rotatably connected within the connecting groove.

[0012] Preferably, the number of nozzles is not less than three and they are centrally symmetrically distributed on the rotating tube, and the nozzles are installed at a downward tilt angle of ten degrees.

[0013] Preferably, the metering component includes an inlet pipe, a one-way valve is fixedly connected to the inlet pipe, a laser level gauge is fixedly connected to the inner top wall of the metering tank, and a controller is fixedly connected to the top of the metering tank.

[0014] Preferably, the inlet pipe is fixedly connected to the metering tank, the controller is electrically connected to the laser level gauge, and the controller controls the one-way valve switch through the output port according to the set logic.

[0015] Compared with existing technologies, the liquid material metering device of this invention, which can clean the inner wall of the metering tank, is not only simple in structure, but also has the following beneficial effects:

[0016] First, after the liquid material is metered and discharged from the metering tank, connect the external water pump to the connecting pipe to draw clean water into the fixed pipe. The clean water enters the nozzle from the rotating pipe and sprays out to rinse the inner wall of the metering tank. When the clean water sprays out from the nozzle, the action and reaction forces, as well as the connecting ring, cause the rotating pipe to rotate in the fixed pipe, which facilitates a thorough rinsing of the inner wall of the metering tank and prevents liquid material from remaining in the metering tank.

[0017] Secondly, the liquid level in the metering tank is measured by a laser level gauge. When the level reaches the threshold, the one-way valve is closed by the controller, achieving the benefit of precise volume control. Attached Figure Description

[0024] For a specific embodiment of a liquid material metering device capable of cleaning the inner wall of a metering tank, please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a metering tank 1, a rinsing assembly 2 on the metering tank 1, and a volume control assembly 3 on the metering tank 1;

[0025] The rinsing assembly 2 includes a fixed tube 201, a connecting tube 202 fixedly connected to the fixed tube 201, a connecting ring 203 rotatably connected inside the fixed tube 201, a rotating tube 204 fixedly connected to the inner side of the connecting ring 203, and a nozzle 205 fixedly connected to the rotating tube 204.

[0026] The inner bottom wall of the measuring container 1 is designed to be inclined and the bottom of the container is fixedly connected to the liquid outlet pipe. The front side of the measuring container 1 is provided with a visual window with scales.

[0027] The inclined inner bottom wall and outlet pipe design of the metering tank 1 facilitate the complete discharge of liquid, reducing residue. The visualization window and scale make liquid level observation and measurement more intuitive, improving operational accuracy.

[0028] The fixed pipe 201 is fixedly connected to the top wall of the metering barrel 1, and the connecting pipe 202 is a flexible hose and is located on the outside of the metering barrel 1.

[0029] The fixed pipe 201 is fixedly connected to the top wall of the metering tank 1 to ensure the stability of the flushing assembly 2. The connecting pipe 202 adopts a flexible hose design and is located on the outside of the tank to facilitate connection to an external water source.

[0030] One side of the fixed tube 201 extends into the interior of the metering barrel 1. A connecting groove is provided inside the fixed tube 201, and the connecting ring 203 is rotatably connected in the connecting groove.

[0031] The fixed tube 201 is rotatably engaged with the connecting ring 203 through the internal connecting groove, so that the rotating tube 204 can rotate flexibly, driving the nozzle 205 to rotate and rinse, covering a wider area and avoiding cleaning dead corners.

[0032] There are no fewer than three nozzles 205, which are centrally symmetrically distributed on the rotating tube 204 and installed at a 10-degree downward angle.

[0033] Multiple nozzles 205 are symmetrically distributed and installed at a downward angle of ten degrees to form a rotating jet of water, which enhances the rinsing effect on the inner wall of the metering tank 1 and improves cleaning efficiency.

[0034] The volume control component 3 includes an inlet pipe 301, a one-way valve 302 fixedly connected to the inlet pipe 301, a laser level gauge 303 fixedly connected to the inner top wall of the metering tank 1, and a controller 304 fixedly connected to the top of the metering tank 1.

[0035] The flow control component 3 controls the unidirectional flow of liquid through the inlet pipe 301 and the one-way valve 302. The laser level gauge 303 is electrically connected to the controller 304 to realize high-precision liquid level detection and automatic opening and closing control, ensuring measurement accuracy.

[0036] The inlet pipe 301 is fixedly connected to the metering tank 1, and the controller 304 is electrically connected to the laser level gauge 303. The controller 304 controls the one-way valve 302 to open and close through the output port according to the set logic.

[0037] The controller 304 controls the one-way valve 302 to open and close based on the signal from the laser level gauge 303, forming a closed-loop management system to prevent overflow or insufficient flow. The inlet pipe 301 is fixedly connected to the metering tank 1 to ensure the sealing and stability of the pipeline.

[0038] Its working principle is as follows: Liquid material enters metering tank 1 through inlet pipe 301 and check valve 302. Laser level gauge 303 monitors the liquid level in real time and transmits the signal to controller 304. When the liquid level reaches the set threshold, controller 304 closes check valve 302 to stop feeding. After metering, the liquid is discharged through the outlet pipe through the inclined inner bottom wall. Then, a water pump is connected to the external pipe 202. Clean water enters the rotating pipe 204 through fixed pipe 201. Under the action of reaction force, the connecting ring 203 rotates, so that multiple inclined nozzles 205 rotate and rinse the inner wall of metering tank 1. After cleaning, the next metering can be carried out.

[0039] Through the above technical solution, under the action of the volume control component 3, the precise control and measurement of body fluid materials can be achieved. Under the action of the rinsing component 2, the metering tank 1 can be automatically cleaned to facilitate the next measurement.
