Description

Technical Field

[0001] This utility model relates to the field of flow meters, specifically a fully welded integrated sanitary electromagnetic flow meter. Background Technology

[0002] Electromagnetic flow meters can quickly measure the volumetric flow rate of liquids and liquid foods, making them ideal for filling applications. They typically have a built-in transmitter and temperature sensor, are lighter in weight, reducing the energy consumption of rotary filling machines, and have a compact design, allowing users to plan and design smaller systems. During operation, they require electrical connection to reduce static electricity generated during liquid flow. Electromagnetic flow meters comply with current regulations in the food and beverage and life science industries. In the food industry, maintaining cleanliness and hygiene is paramount; filling systems must be easy to clean and strictly compliant with hygiene standards. Precise metering is crucial for ensuring consistently high product quality. Since a single filling machine often needs to fill multiple products, a flexible modular system with customizable configurations is essential.

[0003] In existing technologies, the common method is to use bolts to fix the electromagnetic flowmeter. A lug plate structure is installed on the outside of the electromagnetic flowmeter, and then the flowmeter is limited by tightening the bolts. However, the lug plate structure in the existing technology is on the outside of the equipment (if it is on the inside of the equipment, a groove is cut into the outer wall). During the cleaning process, it is difficult for water to flow through the side plate, causing impurities (such as sugar stains) to remain on the inside of the side plate, requiring manual cleaning, which is inefficient. Secondly, after limiting the grounding ring, it needs to be sealed. The existing sealing method uses rubber rings, but the rubber is on the outside, which will isolate the contact between the rubber and the flowmeter, thus interfering with the effect of static electricity discharge. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a fully welded integrated sanitary electromagnetic flow meter to solve the technical problems of easy cleaning and convenient installation of the grounding ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully welded integrated sanitary electromagnetic flowmeter, comprising a lower outer shell, an upper outer shell connected to the top of the lower outer shell, and the lower outer shell and the upper outer shell being welded together; connectors are installed on both sides of the lower outer shell; a grounding ring is installed on the inner wall of the connector; a first sealing ring and a second sealing ring are respectively connected to both sides of the grounding ring; a limiting groove matching the first sealing ring is opened on the inner wall of the connector; a retaining groove is opened on the outer side of the grounding ring; and the second sealing ring is fixedly connected to the grounding ring through the retaining groove.

[0006] By adopting the above technical solution, the joint can be easily installed, and after installation, the joint connection is sealed by each set of sealing rings.

[0007] The present invention is further configured such that limit rings are provided at both ends of the lower outer shell, and a positioning ring is provided on the outer wall of the grounding ring, and the positioning ring is in contact with the limit ring.

[0008] Preferably, it allows for easy positioning and fixing of the grounding ring.

[0009] The present invention is further configured such that the top opening of the lower outer shell is larger than the bottom opening, and the bottom opening of the upper outer shell is larger than the top opening, and the top of the lower outer shell matches the bottom of the upper outer shell in size.

[0010] Preferably, the outer shell is sloped at the top and bottom to facilitate liquid flow.

[0012] Preferably, the connector can be easily fixed.

[0013] The present invention is further configured such that the grounding ring is a plastic part, the depth of the groove is less than the diameter of the second sealing ring, and the second sealing ring is deformed by compression when it is in contact with the outer side of the lower outer shell.

[0014] Preferably, the sealing ring is designed to be deformed by compression, thereby achieving a sealing effect.

[0015] The present invention is further configured such that the outer wall of the positioning ring is fitted with the limiting ring, and the outer side of the positioning ring is fitted with the inner wall of the connector.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Please see Figures 1 to 3 A fully welded integrated sanitary electromagnetic flowmeter includes a lower outer shell 1, with an upper outer shell 2 connected to the top of the lower outer shell 1 and welded together. Limiting rings 101 are provided at both ends of the lower outer shell 1. Connectors 3 are installed on both sides of the lower outer shell 1. A grounding ring 4 is installed on the inner wall of the connector 3. A first sealing ring 5 and a second sealing ring 6 are respectively connected to both sides of the grounding ring 4. A limiting groove matching the first sealing ring 5 is provided on the inner wall of the connector 3. A retaining groove 401 is provided on the outer side of the grounding ring 4, through which the second sealing ring 6 is secured. The groove 401 is fixedly connected to the grounding ring 4. The outer wall of the grounding ring 4 is provided with a positioning ring 402, which fits against the limiting ring 101. The two ends of the connector 3 are respectively connected to the connecting flange 301 and the fixing seat 302. The fixing seat 302 fits against the outer wall of the lower outer shell 1, and fixing bolts 303 are installed at the four corners of the fixing seat 302.

This effectively reduces the dead corners on the outside of the flow meter and reduces liquid residue during use, thereby reducing pollution. Then, the connector 3 is installed on both sides of the lower housing 1. First, the first sealing ring 5 is inserted into the limiting ring inside the connector 3. Then, the grounding ring 4 is installed on the side of the first sealing ring 5. Then, the second sealing ring 6 is installed inside the slot 401 to complete the assembly of the connector 3. Then, the connector 3 is aligned with the outer wall of the lower housing 1 and pushed to fit against the opening of the lower housing 1. At this time, the positioning ring 402 and the limiting ring 101 fit together to initially limit the connector 3 and facilitate alignment. Finally, the connector 3 is installed on the outside of the lower housing 1 by multiple sets of fixing bolts 303, which realizes the installation and improves the installation effect.
