Description

Technical Field

[0001] This utility model relates to the field of heavy metal detection technology in grain and oil food, and in particular to a rapid detection device for heavy metals in grain and oil food. Background Technology

[0002] Grain and oil foods refer to the collective term for cereals, beans, and oil crops, as well as their processed and semi-processed products. They are a major food source for humans and include three main categories: grains, beans, and oil crops. These foods occupy an important position in the diet, providing the human body with the carbohydrates, proteins, and fats it needs. Heavy metals in grain and oil foods mainly include lead, cadmium, mercury, and arsenic. These heavy metals can enter grain and oil foods through various pathways and pose a potential threat to human health. Therefore, it is necessary to test for heavy metals in grain and oil foods to ensure that they meet the standards. Currently, most heavy metal testing methods for grains and oils on the market involve crushing, mixing, reagent fusion, and testing with a heavy metal detector. This method, which requires multiple manual steps, is inconvenient for operators and increases their workload. Therefore, a rapid heavy metal detection device for grains and oils is needed to meet people's needs. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Given that most heavy metal detection methods for grains and oils on the market involve crushing, mixing, reagent fusion, and heavy metal detectors, which require manual operation of multiple steps, this method is inconvenient for operators and increases their workload. Therefore, a rapid heavy metal detection device for grains and oils is needed to meet people's needs.

[0005] Therefore, the purpose of this invention is to provide a rapid detection device for heavy metals in grain and oil foods.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid detection device for heavy metals in grain and oil foods, comprising a detection frame, a rectangular hopper installed at the top of the detection frame, first partition plates installed on the side walls at both ends of the inner side of the detection frame, and a feeding pipe installed inside the first partition plate, a stirring assembly installed at the bottom of the feeding pipe, second partition plates installed below the first partition plates at both ends of the inner side of the detection frame, and third partition plates installed below the second partition plates at both ends of the inner side of the detection frame, with fixing assemblies installed inside each of the third partition plates, a reagent bottle body disposed inside the fixing assembly, a detection instrument installed at the bottom of the inner side of the detection frame, a crushing assembly installed inside the detection frame, and a door panel body hinged to one side wall of the detection frame.

[0007] As a preferred embodiment of the rapid detection device for heavy metals in grain and oil food according to this utility model, a stirring cylinder is installed inside the second partition plate, and a discharge pipe penetrating the second partition plate is installed at the bottom end of the stirring cylinder. A solenoid valve is installed on the outer wall of the discharge pipe, and a horizontal pipe is installed at the bottom end of the discharge pipe, and a vertical pipe is installed at the bottom end of each horizontal pipe.

[0008] By adopting the above technical solution, this solution uses the design of horizontal and vertical pipes to allow the unloading pipe to allow the liquid to enter the interior of the reagent bottle body through the horizontal and vertical pipes.

[0009] As a preferred embodiment of the rapid detection device for heavy metals in grain and oil foods according to this utility model, the crushing component includes a welding plate and a roller body. The roller body is rotatably mounted on the side walls at both ends inside the detection frame via bearings, and grinding rollers are installed on the outer walls of the roller body.

[0010] By adopting the above technical solution, this solution uses the rotation of the roller body to drive the grinding roller to rotate simultaneously, thereby making the grinding roller rotate to grind grain and oil products.

[0011] In a preferred embodiment of the rapid heavy metal detection device for grains and oils according to this utility model, the welding plate is fixedly installed on the side wall of one end of the detection frame, a stepper motor is installed at the top of the welding plate, and a rotating rod body is installed at the output end of the stepper motor through a coupling. One end of the rotating rod body is fixedly connected to one end of the roller body. A sprocket body is installed on the outer wall of the rotating rod body, and a chain body is installed inside the sprocket body.

[0012] By adopting the above technical solution, the sprocket body and the chain body cooperate with each other to make the stepper motor rotate, thereby driving the two sets of roller bodies to rotate simultaneously.

[0013] In a preferred embodiment of the rapid detection device for heavy metals in grain and oil foods according to this utility model, the stirring assembly includes a drive motor, which is fixedly installed at the bottom of a triangular plate. A drive rod is installed at the output end of the drive motor, and a mixing rod is installed on the outer wall of the drive rod.

[0014] By adopting the above technical solution, the drive motor is started to drive the drive rod to rotate, which makes it easy for the drive rod to rotate and drive the mixing rod to rotate at the same time.

[0015] In a preferred embodiment of the rapid detection device for heavy metals in grain and oil foods according to this utility model, the fixing component includes a mounting ring, which is fixedly installed inside the third partition plate. The inner wall of the mounting ring is fitted with an elastic plate, and a high-voltage spring coil is installed inside the elastic plate. The end of the high-voltage spring coil away from the elastic plate is fixedly connected to the inner wall of the mounting ring.

[0016] By adopting the above technical solution and through the design of the high-voltage spring coil, the mounting ring is compressed, causing the elastic plate and the high-voltage spring coil to deform.

[0017] As a preferred embodiment of the rapid detection device for heavy metals in grain and oil foods according to this utility model, a connecting water pipe extending into the stirring cylinder is installed on the side wall of one end of the detection frame, and the connecting water pipe is connected to an external water pipe.

[0018] By adopting the above technical solution, water is connected to an external water pipe through a connecting water pipe, thereby injecting water into the connecting water pipe and allowing it to enter the interior of the mixing cylinder through the external water pipe.

[0019] The rapid detection device for heavy metals in grain and oil foods of this utility model has the following beneficial effects: This invention first utilizes the cooperation between the sprocket body and the chain body, and then drives the rotating rod body to rotate by starting a stepper motor. The rotation of the rotating rod body drives the roller body and the grinding roller to rotate simultaneously through the sprocket body and the chain body. This facilitates the pulverization of grains and oils by rotating two sets of grinding rollers. At the same time, the pulverized grains and oils fall into the interior of the mixing cylinder through the feeding pipe, and are mixed by connecting water pipes and mixing components, thus achieving fully automatic operation and reducing the labor intensity of operators.

[0020] This invention firstly utilizes a solenoid valve design to open and close the discharge pipe, allowing the liquid mixed inside the stirring cylinder to flow into the horizontal pipe and then into the reagent bottle body through the vertical pipe. This allows the detection solution inside the reagent bottle body to mix with the mixed liquid, and then the detection instrument is used to quickly detect heavy metals in grains, oils, and food products.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1: Refer to Figures 1-7 This is the first embodiment of the present invention, which provides a rapid detection device for heavy metals in grains and oils. Currently, most grain and oil food heavy metal detection methods on the market involve crushing, mixing, reagent fusion, and detection using a heavy metal detector. This method requires multiple manual steps, which is inconvenient for operators and increases their workload. Therefore, a rapid detection device for heavy metals in grains and oils is needed to meet user needs. The device includes a detection frame 1, with a rectangular hopper 101 installed at the top. The detection frame 1 has two internal ends... The side wall of the test frame 1 is equipped with a first partition plate 2, and a feeding pipe 201 is installed inside the first partition plate 2. A stirring component 6 is installed at the bottom end of the feeding pipe 201. A second partition plate 3 is installed at both ends of the test frame 1 below the first partition plate 2. A third partition plate 4 is installed at both ends of the test frame 1 below the second partition plate 3. A crushing component 5 is installed inside the test frame 1. A door panel body 103 is hinged to one side wall of the test frame 1. A connecting water pipe 102 that extends into the stirring cylinder 301 is installed on one side wall of the test frame 1, and the connecting water pipe 102 is connected to an external water pipe.

[0027] Combination Figure 1 and Figure 4 In this embodiment of the present invention, a stirring cylinder 301 is installed inside the second partition plate 3, and a discharge pipe 302 penetrating the second partition plate 3 is installed at the bottom end of the stirring cylinder 301. A solenoid valve 3021 is installed on the outer wall of the discharge pipe 302. A horizontal pipe 303 is installed at the bottom end of the discharge pipe 302, and a vertical pipe 304 is installed at the bottom end of each horizontal pipe 303. Through the design of the horizontal pipe 303 and the vertical pipe 304, the discharge pipe 302 allows the liquid to enter the interior of the reagent bottle body 8 through the horizontal pipe 303 and the vertical pipe 304.

[0028] Combination Figure 1 and Figure 2In an embodiment of this utility model, the crushing assembly 5 includes a welding plate 501 and a roller body 504. The roller body 504 is rotatably mounted on the side walls at both ends inside the detection frame 1 via bearings. Grinding rollers 505 are installed on the outer walls of the roller body 504. The welding plate 501 is fixedly mounted on the side wall at one end of the detection frame 1. A stepper motor 502 is installed at the top of the welding plate 501, and a rotating rod body 503 is installed at the output end of the stepper motor 502 via a coupling. One end of the roller body 504 is fixedly connected to the other end of the roller body 503. A sprocket body 506 is installed on the outer wall of the roller body 503, and a chain body 507 is installed inside the sprocket body 506. Through the cooperation of the sprocket body 506 and the chain body 507, the stepper motor 502 is rotated to drive the two sets of roller bodies 504 to rotate simultaneously. The rotation of the roller bodies 504 drives the grinding roller 505 to rotate simultaneously, thereby causing the grinding roller 505 to rotate to grind grains and oils.

[0029] Combination Figure 1 and Figure 3 In an embodiment of this utility model, the stirring assembly 6 includes a drive motor 601, which is fixedly installed at the bottom of the triangular plate 202. A drive rod 602 is installed at the output end of the drive motor 601, and a mixing rod 603 is installed on the outer wall of the drive rod 602. By starting the drive motor 601, the drive rod 602 is driven to rotate, so that the rotation of the drive rod 602 can drive the mixing rod 603 to rotate simultaneously.

[0030] The specific working principle is as follows: when rapid testing of grain and oil products is required, the sprocket body 506 and chain body 507 work together, and the stepper motor 502 is started to drive the rotating rod body 503 to rotate. The rotation of the rotating rod body 503 drives the roller body 504 and grinding roller 505 to rotate simultaneously through the sprocket body 506 and chain body 507. This facilitates the pulverization of grain and oil products by rotating the two sets of grinding rollers 505. At the same time, the pulverized grain and oil products fall into the mixing cylinder 301 through the feeding pipe 201. The pulverized grain and oil products are stirred and mixed by connecting the water pipe 102 and the stirring assembly 6. Simultaneously, the drive motor 601 is started to drive the drive rod 602 to rotate, which in turn drives the mixing rod 603 to rotate and mix the grain and oil products. This achieves fully automatic operation and reduces the labor intensity of operators.

[0031] Example 2: Refer to Figures 1-7This is the first embodiment of the present invention, which provides a rapid detection device for heavy metals in grains and oils. Currently, most grain and oil food heavy metal detection methods on the market involve crushing, mixing, reagent fusion, and detection using a heavy metal detector. This method, requiring multiple manual steps, is inconvenient for operators and increases their workload. Therefore, a rapid detection device for heavy metals in grains and oils is needed to meet user needs. The third partition plate 4 has a fixing component 7 installed inside, and the fixing component 7 has a... The reagent bottle body 8 and the detection frame 1 are equipped with a detection instrument 9 at the bottom. The fixing component 7 includes a mounting ring 701, which is fixedly installed inside the third partition plate 4. The inner wall of the mounting ring 701 is equipped with an elastic plate 702, and a high-voltage spring coil 703 is installed inside the elastic plate 702. The end of the high-voltage spring coil 703 away from the elastic plate 702 is fixedly connected to the inner wall of the mounting ring 701. Through the design of the high-voltage spring coil 703, the mounting ring 701 is compressed, which in turn compresses the elastic plate 702 and the high-voltage spring coil 703, causing them to deform.

[0032] The specific working principle is as follows: First, the design of the solenoid valve 3021 allows it to open and close the discharge pipe 302, enabling the liquid mixed inside the stirring cylinder 301 to flow into the horizontal pipe 303 and then into the reagent bottle body 8 through the vertical pipe 304. This allows the detection solution inside the reagent bottle body 8 to mix with the mixed liquid. Simultaneously, the design of the high-pressure spring coil 703 causes the mounting ring 701 to be compressed, deforming the elastic plate 702 and the high-pressure spring coil 703. The elastic recovery of the high-pressure spring coil 703 then positions and fixes the reagent bottle body 8, facilitating the operator's positioning of the reagent bottle body 8. At the same time, the solution inside the reagent bottle body 8 drips into the detection instrument 9 for rapid detection of heavy metals in grains, oils, and food products.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
