Description

Technical Field

[0001] This utility model relates to the field of chemical analysis sampling technology, specifically a chemical analysis sampling mechanism. Background Technology

[0002] Environmental engineering refers to the design, implementation, and management of various environmental protection projects from the perspective of environmental protection, using various scientific and technological means to reduce environmental pollution and resource waste, protect the ecological environment, and achieve sustainable development. The main tasks of environmental engineering include environmental pollution control, waste treatment, and resource recycling. Sampling devices are required for sampling and analysis when conducting environmental research.

[0003] Chinese Utility Model Patent Application Publication No. CN221006900U discloses a chemical analysis sampling mechanism for environmental engineering, including a base, a support rod mounted on the top of the base, an installation rod mounted on one side of the output end of the support rod, a pneumatic diaphragm pump mounted on the top of the installation rod, and a sampling tube mounted on the bottom of the installation rod. The bottom of the sampling tube is connected to a sampling nozzle, and a sampling tube is mounted on one side of the sampling tube. This utility model utilizes a first solenoid valve and a second solenoid valve. After sampling is completed, when the operator retrieves the sample, the second solenoid valve is opened, and the first solenoid valve above it is closed, allowing the sample to be removed from the sampling tube between the first and second solenoid valves. This achieves quantitative sampling, solving the problem of previous sampling devices being inconvenient for quantitative sampling and helping to improve detection accuracy. Water inlets located at both ends of the first and second solenoid valves allow for the infusion of cleaning agent to rinse the inside of the sampling tube after sampling, facilitating cleaning.

[0004] However, the device cannot be rotated, making it inconvenient to transfer the sampled liquid to another container. It requires manual replacement of the container on the base, resulting in low efficiency. Therefore, we propose a chemical analysis sampling mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a chemical analysis sampling mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chemical analysis sampling mechanism includes a sampling tube with a sampling nozzle fixedly disposed at its bottom. A fixing ring is disposed on the outer surface of the sampling tube. An extension rod is fixedly disposed at one end of the fixing ring, and an electric push rod is fixedly disposed at one end of the extension rod. A fixing seat is fixedly disposed at the bottom of the electric push rod, and a rotating disk is fixedly disposed at the bottom of the fixing seat. A fixing hole is fixedly opened at the bottom of the rotating disk, and a circular ring is fixedly disposed at the bottom of the rotating disk. A fixing plate is disposed below the rotating disk, and a motor is fixedly disposed at the top of the fixing plate. A rotating shaft is fixedly disposed at the output end of the motor, and the rotating shaft is fixedly connected to the fixing hole. A groove is opened at the top of the fixing plate, and the groove matches the circular ring.

[0008] As a further embodiment of this utility model: a base is fixedly provided at the bottom of the fixed plate, and a sampling platform is fixedly provided at the bottom of the base.

[0009] The above solution uses a sampling platform to support the base.

[0010] As a further improvement of this utility model: the top of the sampling platform is provided with a placement groove, and the bottom of the sampling platform is fixedly provided with a support leg.

[0011] The above solution uses support legs to support the sampling platform.

[0012] As a further improvement of this utility model: a storage box is fixedly installed at the bottom of the sampling platform, and a solenoid valve is fixedly installed on one side of the sampling tube.

[0013] The above scheme describes a solenoid valve consisting of a solenoid coil and a valve body. When the solenoid coil is energized, it generates a magnetic field, causing the valve core to overcome resistance such as spring force and move, thereby changing the flow state inside the valve body and achieving on / off control of the fluid. When de-energized, the valve core returns to its initial position under the action of a spring or other reset device, and the state of the fluid passage changes accordingly.

[0014] As a further improvement of this utility model: a strip-shaped hole is provided on one side of the sampling tube, and a glass plate is fixedly installed inside the strip-shaped hole.

[0015] The above solution, by setting up a glass plate, facilitates observation of the internal condition of the sampling tube.

[0016] As a further improvement of this utility model: a pneumatic diaphragm pump is fixedly installed at the top of the sampling tube, and a screw hole is opened on one side of the fixing ring.

[0017] Through the above scheme, the pneumatic diaphragm pump is a fluid transport device that uses compressed air as a power source. It uses air pressure to drive the diaphragm to reciprocate, thereby realizing the intake and discharge of liquid.

[0018] As a further improvement of this utility model: a fixing bolt is threaded inside the screw hole, and a threaded groove is provided on one side of the sampling tube, with one end of the fixing bolt threadedly connected to the threaded groove.

[0019] The above scheme uses a combination of fixing bolts, threaded grooves, and threaded holes to secure the sampling tube in place.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This chemical analysis sampling mechanism, in use, involves placing the beaker containing the sampling material and the beaker to be stored in the placement slots on the top of the sampling platform. During the sampling process, a motor rotates, driving a rotating disk to rotate, thereby allowing the sampling tube to rotate. This rotation facilitates the removal of the sample from the beaker containing the sampling material and its placement into the empty beaker, thus improving the sampling efficiency of the device.

[0022] This chemical analysis sampling mechanism allows for height adjustment of the sampling tube via an electric push rod during sampling, enabling the sampling nozzle to be lowered for easier sampling. A pneumatic diaphragm pump draws liquid into the sampling tube, which is then sealed by a solenoid valve to prevent leakage. When the sampling tube is moved above an empty beaker, the solenoid valve opens, and the pneumatic diaphragm pump operates, allowing the liquid in the sampling tube to flow into the empty beaker. This design enables the device to automatically complete sampling, improving its ease of use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0030] A chemical analysis sampling mechanism includes a sampling tube 1, a sampling nozzle 101 fixedly mounted at the bottom of the sampling tube 1, a fixing ring 2 mounted on the outer surface of the sampling tube 1, an extension rod 3 fixedly mounted at one end of the fixing ring 2, an electric push rod 4 fixedly mounted at one end of the extension rod 3, a fixing seat 5 fixedly mounted at the bottom of the electric push rod 4, a rotating disk 6 fixedly mounted at the bottom of the fixing seat 5, a fixing hole 7 fixedly opened at the bottom of the rotating disk 6, a circular ring 8 fixedly mounted at the bottom of the rotating disk 6, a fixing disk 9 fixedly mounted below the rotating disk 6, a motor 10 fixedly mounted at the top of the fixing disk 9, a rotating shaft 11 fixedly mounted at the output end of the motor 10, the rotating shaft 11 being fixedly connected to the fixing hole 7, and a groove 12 opened at the top of the fixing disk 9, the groove 12 matching the circular ring 8.

[0031] As a further embodiment of this utility model: a base 13 is fixedly installed at the bottom of the fixed plate 9, a sampling platform 14 is fixedly installed at the bottom of the base 13, a placement groove 15 is opened at the top of the sampling platform 14, a support leg 16 is fixedly installed at the bottom of the sampling platform 14, a storage box 17 is fixedly installed at the bottom of the sampling platform 14, a solenoid valve 18 is fixedly installed on one side of the sampling tube 1, a strip hole 19 is opened on one side of the sampling tube 1, a glass plate 20 is fixedly installed inside the strip hole 19, a pneumatic diaphragm pump 21 is fixedly installed at the top of the sampling tube 1, a screw hole 22 is opened on one side of the fixing ring 2, a fixing bolt 23 is threadedly connected inside the screw hole 22, a threaded groove is opened on one side of the sampling tube 1, and one end of the fixing bolt 23 is threadedly connected to the threaded groove.

[0032] Through the above scheme, the sampling platform 14 is set up to support the base 13, and the supporting legs 16 are set up to support the sampling platform 14. The solenoid valve 18 consists of an electromagnetic coil and a valve body. When the electromagnetic coil is energized, it generates a magnetic field, causing the valve core to overcome the resistance such as spring force and displace, thereby changing the flow state inside the valve body and realizing the on / off control of the fluid. When the power is off, the valve core returns to the initial position under the action of the spring and other reset devices, and the state of the fluid passage also changes accordingly. By setting up the glass plate 20, it is convenient to observe the internal condition of the sampling tube 1. The pneumatic diaphragm pump 21 is a fluid conveying device that uses compressed air as a power source. It uses air pressure to drive the diaphragm to reciprocate, thereby realizing the suction and discharge of liquid. Through the combination of fixing bolts 23, threaded grooves and screw holes 22, the fixing ring 2 can fix the sampling tube 1.

[0033] In this embodiment, a chemical analysis sampling mechanism is used by placing the beaker containing the sampling material and the beaker to be stored in the placement slot 15 on the top of the sampling platform 14. During the sampling process, the motor 10 rotates, driving the rotating disk 6 to rotate, thereby allowing the sampling tube 1 to rotate. This rotation facilitates the removal of the sample from the beaker containing the sampling material and its placement into the empty beaker, improving the sampling efficiency of the device. The height of the sampling tube 1 can be adjusted by raising and lowering the electric push rod 4, allowing the sampling nozzle 101 to be lowered for easier sampling. The pneumatic diaphragm pump 21 draws liquid into the sampling tube 1, and then the solenoid valve 18 closes to seal the bottom of the sampling tube 1, preventing liquid leakage. When the sampling tube 1 is moved above the empty beaker, the solenoid valve 18 opens, and the pneumatic diaphragm pump 21 operates, allowing the liquid in the sampling tube 1 to flow out into the empty beaker. Through the above design, the device can automatically complete the sampling, improving the ease of use of the device.
