Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a metering bottle for chemical production. Background Technology

[0002] Chemical metrology is a technical system and practical activity for the precise measurement, control, calibration, and management of key parameters such as the quantity of substances, physical quantities, and chemical quantities throughout the entire chemical production process. It serves as the "eyes" and "benchmark" for the chemical industry to achieve safe production, ensure product quality, improve production efficiency, and reduce energy costs. Its core objective is to ensure that parameters at each stage of chemical production are measurable, controllable, and reliable through precise metrological methods, ultimately guaranteeing stable production processes and product compliance.

[0003] For example, the authorization announcement number "CN205002830U" is titled "A Measuring Bottle with a Quantitative Structure." This bottle uses a drainage tube with a positioning hole between the receiving container and the liquid-filled bottle. The positioning hole on the drainage tube can be flexibly adjusted to the desired scale. Accurate measurement is achieved through the backflow function of the positioning hole. However, existing measuring bottles with quantitative structures require pressure to be applied to the outer wall of the lower bottle body when the liquid is squeezed upwards through the positioning hole. This pressure forces the liquid upwards, but as the liquid flows out, the internal pressure is lost, creating a negative pressure state. This negative pressure then draws in an equal amount of liquid or gas along the positioning hole to maintain gas balance in the lower bottle body. However, this negative pressure suction requires the liquid to flow out through the positioning hole, which can easily lead to secondary suction of the squeezed-out liquid. Adding additional positioning holes or vents can easily cause liquid leakage. How to balance the gas pressure in a measuring bottle with a quantitative structure remains a current challenge. Utility Model Content

[0004] The purpose of this invention is to solve the problem of how to balance the internal air pressure of the bottle after the liquid is squeezed out in existing metering bottles with quantitative structures, and to propose a metering bottle for chemical production.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a metering bottle for chemical production, including a bottle body, a connecting pipe, and a receiving container. The receiving container is fixedly connected to the top of the connecting pipe, and the connecting pipe is movably connected to the top of the bottle body. The inside of the receiving container is provided with a metering pressure balancing structure for a flow tube. The outside of the receiving container is provided with an auxiliary working structure for the metering bottle, and the inside of the bottle body is provided with a metering bottle support and guide structure.

[0007] Preferably, the drainage tube metering pressure balance structure includes a drainage tube and a sealing tube. The drainage tube is slidably connected inside the container. A positioning hole is fixedly opened on the outer wall of the drainage tube. The sealing tube is slidably connected inside the drainage tube. An anti-slip sleeve is fixedly sleeved on the top of the outer wall of the drainage tube. A protrusion is fixedly installed on the top of the sealing tube. A pressure valve is fixedly installed on the top of the outer wall of the bottle.

[0008] Preferably, the lower end of the drainage tube is slidably connected to the top of the bottle, and the outer wall of the lower end of the sealing tube is slidably connected to the inner side of the positioning hole.

[0009] Preferably, the auxiliary working structure of the measuring bottle includes a scale line and a cover plate. The scale line is fixedly connected to the outer wall of the receiving container, and the cover plate is rotatably installed on the top of the receiving container via a hinge. A pouring spout is fixedly connected to one side of the top of the receiving container.

[0010] Preferably, the metering bottle support and guide structure includes a connecting tube and a sleeve. The connecting tube is fixedly installed at the top of the bottle body, the sleeve is fixedly installed inside the bottle body, a supporting hollow block is fixedly connected to the outer side of the bottom end of the sleeve, and a retaining ring is fixedly sleeved on the outer wall of the bottle body.

[0011] Preferably, the outer side of the connecting tube is threadedly connected to the inner side of the communicating tube, the lower end of the sleeve is connected to the inside of the bottle, and the inner side of the sleeve is slidably connected to the lower end of the drainage tube.

[0012] The present invention provides a metering bottle for chemical production, which has the following advantages: as the liquid inside the bottle decreases and the pressure drops, the protrusion can be pressed down to seal the positioning hole, preventing the squeezed solution from flowing back into the bottle. At the same time, the pressure valve on the top of the bottle is opened, allowing outside air to enter the bottle through the pressure valve, keeping the bottle pressure balanced. This prevents the bottle from drying out and becoming difficult to squeeze out later, effectively balancing the internal air pressure of the bottle after the metering work is completed.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example:

[0022] Please see Figures 1-6 In this embodiment, a metering bottle for chemical production includes a bottle body 1, a connecting pipe 2, and a receiving container 3. The receiving container 3 is fixedly connected to the top end of the connecting pipe 2, and the connecting pipe 2 is movably connected to the top end of the bottle body 1. The lower end of the receiving container 3 is connected to the connecting pipe 2, which can be rotatably screwed into the outer thread of the connecting pipe 61 at the top end of the bottle body 1, thereby realizing the installation between the receiving container 3 and the bottle body 1. The inside of the receiving container 3 is provided with a metering pressure balancing structure 4, the outside of the receiving container 3 is provided with a metering bottle auxiliary working structure 5, and the inside of the bottle body 1 is provided with a metering bottle support and guide structure 6.

[0023] The metering pressure balance structure 4 includes a drainage tube 41 and a sealing tube 43. The drainage tube 41 is slidably connected inside the receiving container 3. The drainage tube 41 can be vertically inserted between the bottle body 1 and the receiving container 3. A positioning hole 42 is fixedly opened on the outer wall of the drainage tube 41. The positioning hole 42 is circular and is drilled on the outer wall of the drainage tube 41. The drainage tube 41 enters the bottle body 1, which contains chemical production solution at the lower end, through the sleeve 62. The sealing tube 43 is slidably connected inside the drainage tube 41. An anti-slip sleeve 44 is fixedly sleeved on the top of the outer wall of the drainage tube 41. The anti-slip sleeve 44 is made of rubber material. When it is necessary to measure and measure the chemical liquid, the bottle body 1 contains a sufficient amount of chemical liquid. First, manually pull the protrusion 45 to slide upward until the sealing tube 43 slides upward along the inside of the drainage tube 41, and the bottom end of the sealing tube 43 leaves the inside of the positioning hole 42. Positioning hole 42 will open. Then, grip the anti-slip sleeve 44 and pull out the drainage tube 41, aligning positioning hole 42 with the height of the required measurement scale line 51. Squeeze the lower bottle 1. The external force squeezing the bottle 1 will cause the solution inside the bottle 1 to flow along the lower end of the sleeve 62 into the drainage tube 41, and then flow out through positioning hole 42 on the outside of the drainage tube 41. The outflowing chemical liquid will enter the upper receiving container 3 for storage. Due to the setting of positioning hole 42, the liquid entering the receiving container 3 will have two states: one is that the liquid has not reached the required scale position, and people can squeeze it repeatedly until the liquid is level with the scale position; the other is that it exceeds the required scale, in which case no more squeezing is required, and the liquid is allowed to flow back from the positioning hole 42 into the bottle 1. Continue until the liquid level is reached with the graduation line 51. Finally, pour the accurately measured liquid out of the pouring spout 52 on the receiving container 3 to complete the entire measurement process. At this time, the pressure inside the bottle 1 decreases due to the reduction in liquid. Press down on the protrusion 45 to seal the tube 43 and plug the positioning hole 42 to prevent the squeezed-out solution from flowing back into the bottle 1. At the same time, open the pressure valve 46 on the top of the bottle 1 to allow outside air to enter the bottle 1 through the pressure valve 46, keeping the pressure of the bottle 1 balanced. This will prevent the bottle 1 from drying out and becoming difficult to squeeze out later. This effectively balances the air pressure inside the bottle after the measurement is completed. The top of the sealing tube 43 is fixedly installed with a protrusion 45, and the top of the outer wall of the bottle 1 is fixedly installed with a pressure valve 46.

[0024] The lower end of the drainage tube 41 is slidably connected to the top of the bottle body 1, and the lower outer wall of the sealing tube 43 is slidably connected to the inner side of the positioning hole 42.

[0025] The auxiliary working structure 5 of the measuring bottle includes a scale line 51 and a cover plate 53. The scale line 51 is fixedly connected to the outer wall of the container 3. The scale line 51 is a national standard milliliter scale line, which is used to align with the positioning hole 42 for accurate measurement. The cover plate 53 is mounted on the top of the container 3 by hinge rotation. The cover plate 53 can be flipped to cover the top of the container 3. The cover plate 53 has a through hole inside that allows the drainage tube 41 to slide. A pouring port 52 is fixedly connected to one side of the top of the container 3. The pouring port 52 is set with a triangular slope to facilitate the pouring and flow of liquid.

[0026] The metering bottle support and guide structure 6 includes a connecting pipe 61 and a sleeve 62. The connecting pipe 61 is fixedly installed at the top of the bottle body 1, and the sleeve 62 is fixedly installed inside the bottle body 1. The sleeve 62 is supported inside the bottle body 1 by multiple corrosion-resistant transparent plastic support hollow blocks 64. The sleeve 62 can guide the liquid upward to squeeze into the drainage tube 41. The bottom outer side of the sleeve 62 is fixedly connected to the support hollow block 64. The outer wall of the bottle body 1 is fixedly fitted with a retaining ring 63, which can be placed against the tiger's mouth position for easy handling. The outer side of the connecting pipe 61 is connected to the internal thread of the connecting pipe 2. The lower end of the sleeve 62 is connected to the inside of the bottle body 1, and the inner side of the sleeve 62 is slidably connected to the lower end of the drainage tube 41.

[0027] Working principle:

[0028] Measuring bottles used in chemical production serve as tools for workers to accurately measure liquids in the chemical industry.

[0029] The lower end of the receiving container 3 is connected to the connecting pipe 2, which can be rotated and screwed into the outer thread of the connecting pipe 61 at the top of the bottle body 1, thereby realizing the installation between the receiving container 3 and the bottle body 1. Both the bottle body 1 and the receiving container 3 are made of transparent and corrosion-resistant materials, which are more suitable for the accurate measurement of corrosive and hazardous liquids in industrial applications.

[0030] Then the drainage tube 41 can be vertically inserted between the bottle body 1 and the receiving container 3. The positioning hole 42 is a circle that is drilled on the outer wall of the drainage tube 41. The drainage tube 41 enters the bottle body 1 containing the chemical production solution at the lower end through the sleeve 62. The anti-slip sleeve 44 is made of rubber material.

[0031] When it is necessary to measure and measure a chemical liquid, the bottle 1 contains a sufficient amount of chemical liquid. First, manually pull the protrusion 45 upward until the sealing tube 43 slides upward along the inside of the drainage tube 41. The bottom end of the sealing tube 43 leaves the inside of the positioning hole 42, and the positioning hole 42 will open. Then, hold the anti-slip sleeve 44 and pull the drainage tube 41 so that the positioning hole 42 is aligned with the height of the scale line 51 to be measured. Squeeze the bottle 1 below. The external force will squeeze the solution inside the bottle 1 into the drainage tube 41 along the lower end of the sleeve 62. Then, it will flow out at the positioning hole 42 on the outside of the drainage tube 41. The flowing chemical liquid will enter the upper receiving container 3 for storage.

[0032] Because of the positioning hole 42, the liquid entering the receiving container 3 will have two states: one is that the liquid has not reached the required scale position, and people can squeeze it repeatedly until the liquid is level with the scale position; the other is that it exceeds the required scale, and at this time, no more squeezing is required, but the liquid is allowed to flow back from the positioning hole 42 into the bottle 1 until it reaches the level with the scale line 51. Finally, the accurately measured liquid is poured out from the pouring port 52 on the receiving container 3 to complete the entire measurement process. At this time, the pressure inside the bottle 1 decreases because the liquid decreases. The protrusion 45 can be pressed down to seal the tube 43 to plug the positioning hole 42, preventing the squeezed solution from flowing back into the bottle 1. At the same time, the pressure valve 46 on the top of the bottle 1 is opened to allow outside air to enter the bottle 1 through the pressure valve 46, so that the pressure in the bottle 1 is kept balanced. The bottle 1 will not dry out and become difficult to squeeze out later. This effectively balances the air pressure inside the bottle after the measurement work is completed.

[0033] The scale line 51 is a national standard milliliter scale line, which is used to align with the positioning hole 42 for precise measurement. The cover plate 53 can be flipped to cover the top of the container 3, and a through hole is opened inside the cover plate 53 to allow the drainage tube 41 to slide. A pouring port 52 is fixedly connected to one side of the top of the container 3. The pouring port 52 is set with a triangular slope to facilitate the pouring and flow of liquid.

[0034] The sleeve 62 is supported inside the bottle body 1 by multiple corrosion-resistant transparent plastic support hollow blocks 64. The sleeve 62 can guide the liquid upward into the drainage tube 41. The support hollow block 64 is fixedly connected to the bottom outer side of the sleeve 62. The retaining ring 63 can be placed against the tiger's mouth position for easy handling.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
