Description

Technical Field

[0001] This utility model belongs to the field of sample reduction technology, specifically relating to an automatic sample reducer that can adjust the number of reductions using the quartering method. Background Technology

[0002] Sample reduction refers to the process of proportionally reducing the original sample using standardized operating procedures while maintaining the representativeness of its chemical composition. This step reduces the difficulty of subsequent processing by decreasing the total sample volume, but it is essential to ensure that the reduced subsamples still accurately reflect the physicochemical properties of the original sample.

[0003] Currently, calcium carbide samples are reduced manually using a quartering method. This process generates calcium carbide powder, which adheres to the operator's skin and reacts with sweat to produce gases such as calcium hydroxide (an alkaline and corrosive substance), acetylene, phosphine, and hydrogen sulfide, which can adversely affect the operator's health. Furthermore, the high number of calcium carbide samples tested daily results in high labor intensity for operators and wastes human resources. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an automatic divider that allows for adjustable number of divisions in the quartering method, featuring ease of use and cost-effectiveness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic divider that satisfies the adjustable number of divides in the quartering method, comprising an outer cylinder, a feed hopper fixed to the upper surface of the outer cylinder, an inner cylinder fixed to the upper part of the inner cylinder, a hollow cone installed inside the inner cylinder, discharge ports on both sides of the hollow cone, an analytical sample discharge pipe connected to the bottom of the inner cylinder, and a retained sample discharge port at the bottom of the outer cylinder.

[0006] Preferably, the outer cylinder is symmetrically fixed with fixing frames on both sides, and a perforated plate is inserted into the inside of the fixing frame. The perforated plate is fixed inside the fixing frame by fastening bolts.

[0007] Preferably, the upper surface of the fixing frame is provided with a plurality of positioning holes.

[0008] Preferably, the bottom end of the inner cylinder is configured as a funnel-shaped structure.

[0009] Preferably, the hollow cone is divided into four parts, one of which has a material discharge port at one diagonal, and the material discharge port is 2 / 3 hollowed out at one diagonal of the hollow cone.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention eliminates the harm to the human body caused by the spillage of calcium carbide sample powder during the reduction process by directly feeding the sample into the hopper; it reduces the manual sample retention process during sample reduction; and the reduction structure can be added or removed according to the total amount of sample. It is highly practical, applicable to the reduction of various samples, and the device has a simple structure, low investment, high practicality, good reduction effect, and reduced operating costs.

[0013] 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.

[0014] Example 1 Please see Figure 1-3 The present invention provides the following technical solution: an automatic divider that satisfies the adjustable number of divides in the quartering method, comprising an outer cylinder 2, a feed hopper 1 fixed on the upper surface of the outer cylinder 2, an inner cylinder 8 fixed on the upper part of the inner cylinder 2, a hollow cone 9 installed inside the inner cylinder 8, a discharge port 10 opened on both sides of the hollow cone 9, an analytical sample discharge pipe 3 connected to the bottom end of the inner cylinder 8, and a sample retention discharge port 11 opened at the bottom end of the outer cylinder 2.

[0015] Specifically, the outer cylinder 2 is symmetrically fixed with fixing brackets 5 on both sides, and a perforated plate 4 is inserted into the inside of the fixing bracket 5. The perforated plate 4 is fixed inside the fixing bracket 5 by fastening bolts 7.

[0016] By adopting the above technical solution, when multiple sample reductions are required, multiple sets of outer cylinders 2 can be assembled. The analytical sample outlet pipe 3 inside the upper set of outer cylinders 2 is connected to the feed hopper 1 at the upper end of the lower set of outer cylinders 2. The perforated plate 4 slides along the inside of the fixing frame 5 and is fixed by fastening bolts 7 through the positioning holes 6. The perforated plate 4 inside the upper set of outer cylinders 2 is moved to the left, and the perforated plate 4 inside the lower set of outer cylinders 2 is moved to the right. The two sets of perforated plates 4 are then connected and assembled, so that the analytical sample outlet pipe 3 and the feed hopper 1 can directly correspond. This improves the convenience of equipment use. The outer cylinders 2 can be added according to the usage requirements to achieve multi-stage reduction, improve reduction efficiency, ensure the flexibility of equipment use, and eliminate the spillage of calcium carbide sample powder in the air during the reduction process. Excess sample enters the sample retention tank directly from the outer cylinder 2, reducing the step of manual reduction and sample loading by operators, and improving work efficiency.

[0017] Specifically, the upper surface of the fixing frame 5 is provided with several positioning holes 6.

[0018] By adopting the above technical solutions, the convenience and stability of the perforated plate 4 positioning installation are improved, ensuring the quality of equipment use.

[0019] Specifically, the bottom of the inner cylinder 8 is designed with a funnel-shaped structure.

[0020] By adopting the above technical solution, the shrunk sample can fall quickly, preventing blockage.

[0021] Specifically, the hollow cone 9 is divided into four parts, one of which has a material outlet 10 at one diagonal. The material outlet 10 is a 2 / 3 hollowed-out section at one diagonal of the hollow cone 9.

[0022] By adopting the above technical solution, the stability of the sample feeding during sample reduction is ensured, and the reduction efficiency is improved.

[0023] The working principle and usage process of this utility model are as follows: When using this utility model to reduce the sample by quartering, the sample is put into the inner cylinder 2 from the feed hopper 1. The sample falls on the upper end of the hollow cone 9 inside the inner cylinder 8. Part of the sample enters the analytical sample discharge pipe 3 from the drop port 10 and is discharged. The remaining sample enters the inner cylinder 2 from the other opposite corner of the hollow cone 9 and falls into the sample retention tank from the sample retention outlet 11 for collection. This completes one sample quartering reduction. When multiple sample reductions are required, multiple sets of outer cylinders 2 can be assembled. The analytical sample outlet pipe 3 inside the upper set of outer cylinders 2 is connected to the feed hopper 1 at the upper end of the lower set of outer cylinders 2. The perforated plate 4 slides along the inside of the fixing frame 5 and is fixed by fastening bolts 7 through the positioning holes 6. The perforated plate 4 inside the upper set of outer cylinders 2 is moved to the left, and the perforated plate 4 inside the lower set of outer cylinders 2 is moved to the right. The two sets of perforated plates 4 are then connected and assembled so that the analytical sample outlet pipe 3 directly corresponds to the feed hopper 1, improving the convenience of equipment use. The outer cylinders 2 can be added according to the usage requirements to achieve multi-stage reduction, improve reduction efficiency, ensure the flexibility of equipment use, and eliminate the spillage of calcium carbide sample powder in the air during the reduction process. Excess sample enters the sample retention tank directly from the outer cylinder 2, reducing the step of manual reduction and sample loading by operators, and improving work efficiency.
