Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a ton-barrel sampling machine. Background Technology

[0002] Sampling of bulk liquid in bulk containers is a crucial step in product quality control. Typically, chemical bulk liquid manufacturers need to conduct sampling and analysis after product bottling to perform quality control tasks such as metal ion precipitation detection and chemical composition analysis.

[0003] Currently, common sampling methods include: taking samples of the filling liquid from the filling equipment, and using metering pumps to extract the original liquid from the finished product container.

[0004] However, these sampling methods all have their own drawbacks in practical use. For example, taking samples of the liquid being filled in the filling equipment can only be done during the filling process, which has a limited time window and the samples may not fully represent the quality of the final product. While using a metering pump to extract the original liquid from the finished product container allows for precise control of the sampling volume, the metering pump has a complex structure, high maintenance costs, and electric pumps pose safety hazards in flammable and explosive environments.

[0005] Therefore, there is an urgent need for a new type of ton-bucket sampling equipment. Utility Model Content

[0006] This utility model provides a ton-bucket sampling machine, which aims to solve the defects of existing ton-bucket sampling methods in practical applications.

[0007] In a first aspect, this utility model provides a ton-bucket sampling machine. The ton-bucket sampling machine includes: an equipment support frame with several mounting positions formed within it; a support cover fixed to the equipment support frame, forming the outer surface of the equipment; a sampling box fixedly mounted on the equipment support frame; a sampling pipe extending one end to the ton-bucket containing area and connected to the sampling box; a vacuum pump connected to the sampling box via a first connecting pipe to create negative pressure within the sampling box; a buffer tank fixedly mounted on the equipment support frame and connected to the sampling box via a second connecting pipe; a sampling and drainage control pump mounted on the second connecting pipe; and a diaphragm pump connected to the buffer tank via a third connecting pipe to drive the liquid in the buffer tank to drain.

[0008] Optionally, the ton sampler further includes: a first regulator for connecting to an external gas source to form a gas output with a target gas pressure; a gas replenishment pipe, one end of which extends to the ton container area and the other end of which is connected to the first regulator; and a gas replenishment control pump, which is mounted on the gas replenishment pipe.

[0009] Optionally, the ton-shaped sampler further includes: a cleaning pipe, one end of which forms a pure water inlet, and the other end of which is connected to the sampling box; and a cleaning control pump, which is mounted on the cleaning pipe.

[0010] Optionally, the ton sampler further includes a vacuum pump solenoid valve, which is used to control the flow rate of control gas supplied to the vacuum pump to control the operating status of the vacuum pump.

[0011] Optionally, the cover includes: a first cabinet door that can be opened and closed, the first cabinet door being disposed in the ton container area; and a second cabinet door that can be opened and closed, the second cabinet door being disposed at the location of the sampling box.

[0012] The beneficial effects of the ton-bucket sampler provided in this embodiment of the invention are as follows: This ton-bucket sampler uses gas pressure sampling, avoiding the direct use of electric pumps, and has significant advantages in safety and reliability. Furthermore, the negative pressure generated by the vacuum pump prevents the diffusion and leakage of sampled chemicals, thus improving safety. Attached Figure Description

[0017] This invention provides a ton-bucket sampling machine. It uses nitrogen as the main power source to pump the raw liquid inside the ton-bucket into a sampling box. The sampling box utilizes a vacuum pump to create a negative pressure environment.

[0018] like Figure 1 and Figure 2 As shown, the ton-shaped sampler includes: an equipment support 10, a support cover 20, internal pipelines 30, and a sampling box 40.

[0019] The equipment bracket 10 has several mounting positions, and the internal pipelines 30 are fixedly installed at the corresponding positions on the equipment bracket 10. The bracket cover 20 is installed and fixed on the outside of the equipment bracket 10, forming the outer surface of the equipment, to cover and protect the internal pipelines 30.

[0020] Please continue reading. Figure 1 and Figure 2The equipment support 10 has a container area for ton containers. The ton container T to be sampled can be placed in this area. The sampling box 40 is fixedly mounted on the equipment support 10 and has a set size to hold the sampling bottle.

[0021] Specifically, such as Figure 2 As shown, the cover provided in the ton container area includes a first cabinet door 21. This first cabinet door 21 can be opened and closed, facilitating the movement of the ton container in and out. The cover provided in the sampling box 40 includes a second cabinet door 22. Users can place or remove sampling bottles by opening and closing the second cabinet door 22.

[0022] In some embodiments, the sampling box 40 is configured as a glove box. Operators can perform sampling operations using gloves attached to the box to avoid direct contact with chemicals.

[0023] like Figures 4 to 6 As shown, the internal pipeline 30 includes: a sampling pipeline 301, a vacuum pump 302, a buffer tank 303, a first connecting pipeline 304, a second connecting pipeline 305, a third connecting pipeline 306, a sampling and drainage control pump 307, a diaphragm pump 308, a regulator 309, a gas replenishment pipeline 310, a gas replenishment control pump 311, a cleaning pipeline 312, and a cleaning control pump 313.

[0024] One end of the sampling pipe 301 extends to the container area, and the other end of the sampling pipe 301 is connected to the sampling box 40. The vacuum pump 302 is connected to the sampling box 40 through the first connecting pipe 304 to create a negative pressure environment inside the sampling box 40.

[0025] In some embodiments, a vacuum pump bypass control valve 314 is also provided in the first connecting pipe 304 for controlling the gas flow rate of the first connecting pipe 304.

[0026] The buffer tank 303 is fixedly mounted on the equipment bracket and connected to the sampling box 40 via the second connecting pipe 305. The buffer tank 303 is a device for temporarily storing cleaning liquid or other types of waste liquid.

[0027] A sampling and drainage control pump 307 is installed on the second connecting pipe 305 to control the connection or disconnection of the second connecting pipe 305. A diaphragm pump 308 is connected to the buffer tank 303 via a third connecting pipe 306 to drive the liquid temporarily stored in the buffer tank 303 to be discharged.

[0028] Regulator 309 is used to connect to an external gas source (e.g., nitrogen) and is a component used to regulate gas pressure. It adjusts the external high-pressure gas source to the target pressure and outputs it according to actual needs.

[0029] One end of the gas supply pipe 310 extends to the ton container area, and the other end of the gas supply pipe 310 is connected to the regulator 309 so that the gas output by the regulator 309 enters the ton container.

[0030] The air supply control pump 311 is installed on the air supply pipeline 310 and is used to control the connection or disconnection of the air supply pipeline 310.

[0031] One end of the cleaning pipe 312 forms a pure water inlet, which is connected to a pure water source. The other end of the cleaning pipe 312 is connected to the sampling box 40 to provide cleaning solution to the sampling box 40.

[0032] The cleaning control pump 313 is installed on the cleaning pipeline 312 and is used to control the connection or disconnection of the cleaning pipeline.

[0033] In practical applications, the ends of the gas replenishment pipeline 310 and the sampling pipeline 301 are both connected to the ton container in the container holding area. The gas delivered by the gas replenishment pipeline 310 is sent into the ton container, giving it a certain pressure.

[0034] The sampling box 40 contains a sampling bottle to receive the original liquid sample. The vacuum pump 302 is started to maintain a vacuum environment inside the sampling box 40. At this time, a pressure difference (provided by the gas supply pipe 310) is formed between the sampling pipe 301 at one end of the sampling box 40 and the other end inside the container, driving the original liquid in the container to flow through the sampling pipe 301 into the sampling box 40.

[0035] When it is necessary to clean the sampling bottle, the cleaning control pump 313 is turned on, so that pure water enters the sampling box 40 through the cleaning pipe 312 for cleaning.

[0036] After sampling is completed, vacuum pump 302 is turned off and diaphragm pump 308 is turned on. At this time, the waste liquid and cleaning liquid in sampling box 40 enter the buffer tank 303 through the second connecting pipe 305 (the sampling and drainage control pump 307 controls the second connecting pipe 305 to open at this time) and are further pumped to the outside of the ton sampler.

[0037] Specifically, the vacuum pump 302 is a pneumatically controlled vacuum pump. The ton sampler also includes a vacuum pump solenoid valve 50 for use with it. This solenoid valve 50 controls the flow rate of the control gas supplied to the vacuum pump via the gas pipeline, thereby controlling the operating status of the vacuum pump.

[0038] In some embodiments, such as Figure 4 and Figure 6As shown, there are multiple regulators, labeled REG(G), REG(D), REG(P1), and REG(V). These regulators are used to provide different gas pressures and gases for use by various devices of the ton sampler.

[0039] For example, regulator REG(G) is used to supply clean gas to the air gun and sampling box. Regulator REG(D) is used for replenishing gas to the tonne tank, supplying gas to the replenishment pipeline. Regulator REG(D) is used to supply gas to the vacuum pump solenoid valve, enabling the vacuum pump solenoid valve to control the operation of the vacuum pump. Regulator REG(V) is used to supply gas to the various connected pumps, enabling on / off state control of these connected pumps.

[0040] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and all of these fall within the protection scope of the present invention.
