Description

Technical Field

[0001] The utility model belongs to the technical field related to mass flow meters, and in particular relates to a mass flow meter used in the production of chemical products. Background Art

[0002] Mass flow meters used in chemical production precisely measure the mass flow of fluids. By directly measuring the mass of the fluid, they provide more accurate data than volumetric flow meters. This is crucial for chemical production, which demands high ratio control and product quality. Key types include Coriolis mass flow meters (high accuracy, suitable for a variety of fluids) and thermal mass flow meters (suitable for gas flow and fast response). These flow meters can monitor flow in real time, optimize production processes, and reduce material waste.

[0003] However, the mass flowmeter used in chemical production is mainly used to measure the mass flow rate of the fluid rather than the volume flow rate. When the chemical fluid raw material passes through the mass flowmeter, the monitoring probe of the mass flowmeter will monitor the mass flow rate of the passing fluid in real time and display the monitored data in real time. The flowmeter host that displays the information is located outside the mass flowmeter, and the flowmeter host and the mass flowmeter are connected and sealed through a sealing seat. However, when the flowmeter host is hit by an external force, the impact force will be concentrated on the sealing seat through the flowmeter host, which will easily cause deformation and damage to the sealing seat, thereby causing leakage in the sealing seat at the connection between the flowmeter host and the mass flowmeter, causing the mass flowmeter to be unable to be used normally. Utility Model Content

However, when the flow meter main body is impacted by an external force, the impact force will be concentrated on the sealing seat through the flow meter main body, which will easily cause deformation and damage to the sealing seat.

[0006] The flow meter protection device includes a metal fixing strip, a U-shaped protection frame and a rubber protection pad. The U-shaped opening of the U-shaped protection frame is set downward, and the U-shaped protection frame is sleeved on the outside of the flow meter main unit. The curved inner wall at the top of the U-shaped protection frame is provided with a rubber protection pad. The rubber protection pad is attached to the curved outer wall of the upper half of the flow meter main unit. Metal fixing strips are provided at both ends of the bottom of the U-shaped protection frame.

[0007] Preferably, the flow meter protection device also includes a metal fixing ring and fixing screws. Two metal fixing rings are provided. Both metal fixing rings are sleeved on the outside of the flow tube body. The two metal fixing rings are symmetrically arranged on the left and right sides of the flow meter connecting seat. The two metal fixing strips are respectively located at the top of the two metal fixing rings. The metal fixing strips are fixedly connected to the metal fixing rings by multiple fixing screws.

[0008] Preferably, when the rubber protective pad is in contact with the outer wall of the flow meter main body, the outer wall of the bottom end of the metal fixing strip does not contact the outer wall of the top end of the metal fixing ring, and the U-shaped protective frame and the metal fixing strip are fixedly connected by welding. The U-shaped protective frame and the metal fixing strip are both made of aluminum alloy.

[0009] Preferably, a feed flange is provided at the left end of the flow tube body, and a discharge flange is provided at the right end of the flow tube body. A plurality of screw holes are equidistantly provided inside the feed flange and the discharge flange.

[0010] Preferably, a data display screen is provided inside the front end of the flow meter main unit, a transparent protective glass is provided on the front side of the data display screen, and the transparent protective glass is sealed at the front end of the flow meter main unit.

[0012] Compared with the existing technology, the utility model provides a mass flow meter for chemical production, which has the following beneficial effects:

[0013] The U-shaped protective frame is fixed on the outside of the flow meter main body by screws, so that the U-shaped protective frame can be firmly fixed on the outside of the flow meter main body. When the flow meter is hit by an external force, the U-shaped protective frame protecting the outside of the flow meter main body can help the flow meter share the external force impact and concentrate the impact force generated by the external force impact on the U-shaped protective frame, thereby avoiding the deformation and damage of the sealing seat caused by the external force of the flow meter main body.

A feed flange 1 is provided at the left end of the flow tube body 2, and a discharge flange 3 is provided at the right end of the flow tube body 2. A plurality of screw holes are equidistantly provided inside the feed flange 1 and the discharge flange 3. A data display screen 7 is provided inside the front end of the flow meter main unit 6, and a transparent protective glass is provided on the front side of the data display screen 7, and the transparent protective glass is sealed at the front end of the flow meter main unit 6. A mass flow probe rod 10 is provided at the bottom end of the flow meter main unit 6, and the bottom end of the mass flow probe rod 10 passes through the sealing seat 5 and the flow meter connecting seat 4 in sequence and is located inside the flow tube body 2. A monitoring probe 9 is provided at the bottom end of the mass flow probe rod 10. When installing the mass flowmeter for the production of chemical products, it is first necessary to screw the feed flange 1 at the left end of the flow tube body 2 and the discharge flange 3 at the right end. After the sealing seat 5 is installed on the top of the flow meter connecting seat 4, the flow meter host 6 is pre-installed on the top of the sealing seat 5. After the sealing seat 5 is installed on the top of the flow meter connecting seat 4, the mass flow probe 10 at the bottom of the flow meter host 6 is inserted into the flow tube body 2. At the same time, the monitoring probe 9 at the bottom of the mass flow probe 10 is also located inside the flow tube body 2. When the chemical production raw materials pass through the flow tube body 2, the monitoring probe 9 located inside the flow tube body 2 will monitor the mass flow of the chemical raw materials passing through the flow tube body 2 in real time, and transmit the monitored data back to the processing module inside the flow meter host 6 through the mass flow probe 10. The processing module will analyze and process the transmitted data and obtain real-time mass flow information. The mass flow information will then be displayed on the data display screen 7, making it convenient for users to record the mass flow information in a timely manner.

[0021] like Figure 1 、 Figure 3 and Figure 4As shown, the flow meter host 6 is connected to the outer wall of the flow tube body 2 with a flow meter protection device 8, the flow meter protection device 8 includes a metal fixing strip 12, a U-shaped protection frame 13 and a rubber protection pad 14, the U-shaped protection frame 13 U-shaped opening is set downward, the U-shaped protection frame 13 is sleeved on the outside of the flow meter host 6, the top arc-shaped inner wall of the U-shaped protection frame 13 is provided with a rubber protection pad 14, the rubber protection pad 14 is attached to the upper half of the arc-shaped outer wall of the flow meter host 6, the bottom two ends of the U-shaped protection frame 13 are provided with metal fixing strips 12, the flow meter protection device 8 also includes a metal fixing ring 11 and a fixing screw 15, the metal fixing ring 11 There are two of them, and both metal fixing rings 11 are sleeved on the outside of the flow tube body 2. The two metal fixing rings 11 are symmetrically arranged on the left and right sides of the flow meter connecting seat 4. The two metal fixing bars 12 are respectively located at the top ends of the two metal fixing rings 11. The metal fixing bars 12 and the metal fixing rings 11 are fixedly connected by multiple fixing screws 15. When the rubber protective pad 14 is in contact with the outer wall of the flow meter main body 6, the outer wall of the bottom end of the metal fixing bar 12 does not contact the outer wall of the top end of the metal fixing ring 11. The U-shaped protective frame 13 is fixedly connected to the metal fixing bar 12 by welding. The U-shaped protective frame 13 and the metal fixing bar 12 are both made of aluminum alloy.

[0022] like Figure 1 、 Figure 3 and Figure 4 As shown, when the mass flow meter for chemical production is put into use, in order to increase the protection of the flow meter host 6, it is necessary to install the flow meter protection device 8 to the outside of the flow meter host 6. Specifically, the U-shaped protection frame 13 needs to be sleeved on the outside of the flow meter host 6 with the U-shaped opening facing downward. After it is fully sleeved, the rubber protection pad 14 on the arc-shaped inner wall of the top of the U-shaped protection frame 13 fits on the arc-shaped outer wall of the upper half of the flow meter host 6, and the metal fixing strips 12 at both ends of the bottom of the U-shaped protection frame 13 are respectively located on the upper side of the two metal fixing rings 11 outside the flow tube body 2, and then the metal fixing strips 12 and the metal fixing rings 11 are directly connected and fixed together with screws. When the fixing screws 15 are tightened, they will pull downward. The U-shaped protective frame 13 is firmly sleeved and fixed on the outside of the flow meter main body 6, and the rubber protective pad 14 can protect the flow meter main body 6 from damage. In this way, when the flow meter main body 6 is subjected to external force, the U-shaped protective frame 13 sleeved and fixed on the outside of the flow meter main body 6 will resist most of the impact force, and share the impact force acting on the U-shaped protective frame 13 to the two metal fixing rings 11 and the flow tube body 2, so that the impact force acting on the flow meter main body 6 can be greatly weakened, so that the sealing seat 5 connecting the flow meter main body 6 and the flow meter connecting seat 4 can be protected from damage by the impact force, ensuring that the sealing seat 5 can always be in a sealed state to avoid leakage.
