Description

Technical Field

[0001] This utility model belongs to the field of sampling and testing technology, specifically relating to a sampler for liquid hazardous chemicals and industrial wastewater. Background Technology

[0002] Currently, when sampling from tank tops or wastewater ditches, the common practice is to directly sample using sampling bottles or to transfer samples to sampling bottles after sampling with ordinary samplers. This poses safety hazards such as burns to sampling personnel and skin corrosion from contact with hazardous chemicals. Furthermore, the sampling process involves swinging the sampler to allow the liquid to enter the sampler from the top, which is complicated and violates the principle of simplifying the process. Therefore, a new sampler is needed to replace the commonly used samplers. Utility Model Content

[0003] The purpose of this utility model is to provide a liquid hazardous chemical and industrial wastewater sampler that is relatively simple to operate, easy to install and maintain, and safe and reliable.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sampler for liquid hazardous chemicals and industrial wastewater, comprising a sampler body, a handle buckle, a handle connector, a handle, and a bottom sampling valve;

[0005] The sampler body is a cylinder with a pair of vertically facing handle buckles symmetrically arranged on one side. The handle buckles are fixedly connected to the sampler body. One end of the handle connector is nested into the handle buckle. The handle is fixedly connected to the other end of the handle connector. The combination of the handle buckle, the handle connector, and the handle is used to move the sampler body. The bottom sampling valve is located at the bottom of the sampler body.

[0006] Furthermore, the sampler is provided with an overflow outlet at its top.

[0007] Furthermore, the handle buckle is an inverted U-shape with the opening facing downwards.

[0008] Furthermore, the sampler body is welded to the handle buckle, and the handle connector is welded to the handle.

[0009] Furthermore, the bottom sampling valve adopts a one-way valve with a circular structure. It uses a cut semicircle to set a movable opening inside the semicircle. The outer side of the semicircle is provided with a sealing semi-ring, which is fastened to the sampler body by a threaded nut.

[0010] Furthermore, the sampler body and the handle buckle are made of 2mm thick 304 stainless steel.

[0011] Furthermore, the inner and outer surfaces of the sampler body and the handle are sprayed with a high-temperature resistant and corrosion-resistant coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The handle of the sampling device of this utility model is installed by directly upward fitting, and can be directly installed after sampling to safely transfer the liquid sample to the sampling bottle. This can effectively prevent safety hazards such as burns and hand corrosion caused by the sampler being moved to the sampling bottle after sampling. It is easy to disassemble and meets the inherent safety requirements of the device; (2) The bottom one-way valve of this utility model is installed by using a threaded nut fastening method, which increases operability and reduces the difficulty of later maintenance; (3) The sampler and handle of this utility model are sprayed with organic silicon high temperature resistant anti-corrosion coating on the inner and outer surfaces, which can avoid metal rust and corrosion, greatly improve the service life of the sampler, and meet the current concept of saving costs from every drop.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] This utility model relates to a sampler for liquid hazardous chemicals and industrial wastewater, combined with Figure 1 It includes the sampler body 1, handle buckle 2, handle connector 3, handle 4, and bottom sampling valve 5;

[0021] The sampler body 1 is cylindrical, with a pair of vertically opening handles 2 symmetrically arranged on one side. The handles 2 are fixedly connected to the sampler body 1. Figure 2 One end of the handle connector 3 is nested into the handle buckle 2, and the handle 4 is fixedly connected to the other end of the handle connector 3. Therefore, the handle 4 is also directly nested into the handle buckle 2 through the handle connector 3 to achieve integration. The combination of the handle buckle 2, the handle connector 3, and the handle 4 is used to move the sampler body 1. This design is to facilitate direct fitting after sampling and to prevent human hands from touching the sampler or sample, which could cause burns or corrosion to the hands. The bottom sampling valve 5 is located at the bottom of the sampler body 1.

[0022] The handle buckle 2 is an inverted U-shape with the opening facing downwards.

[0023] The sampler is equipped with an overflow outlet at the top, which facilitates the transfer of the sample to the sampling bottle after sampling.

[0024] The sampler body 1 is welded to the handle buckle 2, and the handle connector 3 is welded to the handle 4.

[0025] Combination Figure 3 The bottom sampling valve 5 adopts a one-way valve with a circular structure. It uses a cut semicircle to set a movable opening with an inner semicircle with a radius of 3.5cm. The outside of the semicircle is provided with a PTFE sealing semi-ring, which is fastened to the sampler body 1 by a threaded nut, increasing operability and reducing the difficulty of later maintenance.

[0026] The sampler body 1 and the handle buckle 2 are made of 2mm thick 304 stainless steel.

[0027] The inner and outer surfaces of the sampler body 1 and the handle 4 are sprayed with a high-temperature resistant and anti-corrosion coating. Zhisheng brand ZS series organosilicon heat-resistant and anti-corrosion coating can be selected, which can resist high temperature of 200℃ and corrosion from most chemicals, except for substances with strong oxidizing and acidic properties such as trichloroethylene.

[0028] The sampler body 1 has a cylindrical body length of 24cm, a radius of 7cm, and a maximum sampling volume of 750ml.

[0029] The handle connector 3 is made of ordinary stainless steel and measures 0.5cm x 2.2cm.

[0030] The handle 4 is a semi-circular ring with a thickness of 0.5cm, an outer diameter of 5.2mm, and an inner diameter of 4.7cm.

[0031] The working method of this utility model:

[0032] Using a rope, the sampler is lowered to prevent liquid sample from reaching the surface. Due to the sampler's own weight, the bottom sampling valve 5 opens due to the upward thrust of the liquid surface, allowing liquid to enter the sampler from bottom to top. During the upward pulling process after sampling, the bottom valve closes due to the downward force of the liquid's gravity. After placing the sampling valve containing the sample on a horizontal surface, the handle is... Figure 2 As shown, by inserting the handle buckle 2 from bottom to top, the sample can be transferred to the sampling bottle without touching the human skin, reducing the risk of burns or corrosion to the sampling personnel and completing the sampling safely.

[0033] The principle of this utility model:

[0034] During sampling, the bottom of the sampler is buoyed upward by the liquid surface, which opens the valve at the bottom of the sampler. Liquid enters the sampler from the bottom. After liquid has entered the sampler, it is lifted upward by the gravity of the liquid inside the sampler, which closes the one-way valve at the bottom, thus completing the safe sampling.
