Description

Technical Field

[0001] This utility model relates to the field of heavy metal digestion technology, and in particular to a heating digestion device for detecting heavy metals in grains. Background Technology

[0002] In recent years, heavy metal pollution in grains has become increasingly prominent, with mercury, cadmium, lead, and arsenic being particularly concerning. These heavy metals enter the grain production environment through atmospheric deposition, wastewater irrigation, and industrial waste emissions, leading to excessive levels of heavy metals in grains and posing a potential threat to human health. Currently, heavy metal testing is conducted on grains before they are sold on the market. Grains with excessive heavy metal levels are treated with heat digestion devices to reduce their heavy metal content and bring them up to food safety standards.

[0003] The prior art patent with publication number CN216117045U discloses a digestion device for the pretreatment of heavy metal detection in agarwood tea. This device removes heavy metals from tea leaves by heating the digestion solution. However, after the heavy metals are removed, it is inconvenient to separate and classify the waste liquid and tea leaves for collection. Similarly, when it is applied to the digestion of heavy metals in grains, it is also inconvenient to separate and collect the waste liquid and grains. Therefore, a heated digestion device for heavy metal detection in grains is needed to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a heating and digestion device for detecting heavy metals in grains, so as to solve the problems mentioned in the background art.

[0024] 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.

[0025] Example:

[0026] like Figure 1-5As shown, this embodiment provides a grain heavy metal detection and heating digestion device, including a base plate 1 for heating and digesting heavy metals in grain. It also includes a heavy metal digestion component 2, mounted on the base plate 1, for digesting heavy metals in the grain. The heavy metal digestion component 2 includes a frame 21 mounted on the base plate 1, a digestion chamber 22 mounted on the frame 21, a heating inner liner 23 installed inside the digestion chamber 22, a stirring mechanism 24 mounted on the digestion chamber 22, and a temperature controller 25 mounted on the frame 21. Grain with excessive heavy metals is placed in the digestion chamber 22, and digestion solution is poured in simultaneously. The heating temperature of the heating inner liner 23 is adjusted by the temperature controller 25, and the heating inner liner 23 heats and digests the heavy metals in the grain. The stirring mechanism 24 stirs the grain in the digestion chamber 22, ensuring uniform heating and digestion of heavy metals, resulting in a good heavy metal digestion effect.

[0027] In order to classify and collect grains after heavy metal desorption and waste liquid after use. Release component 3, located at the bottom of digestion chamber 22, is used for the classified release of grain and digestion waste liquid. Release component 3 includes a collection hopper 31 installed at the bottom of digestion chamber 22, a release pipe 32 installed at the bottom of collection hopper 31, a main cover 33 detachably installed inside release pipe 32, a filter screen 34 installed inside main cover 33, and a secondary cover 35 detachably installed inside main cover 33. Cover removal and installation mechanisms 36 are provided on release pipe 32 and main cover 33, and secondary cover removal and installation mechanisms 37 are provided on main cover 33 and secondary cover 35. After heavy metal digestion is completed, the secondary cover 35 is pulled out from the main cover 33 through secondary cover removal and installation mechanism 37. The filter screen 34 can filter the digested grain, and the digested waste liquid will be released through filter screen 34. The main cover 33 can be pulled out through cover removal and installation mechanism 36, and the grain that has been digested for heavy metals will be released through release pipe 32, which facilitates the classified collection of grain and digestion waste liquid.

[0028] Specifically, to ensure uniform heating of the grain, the stirring mechanism 24 includes a top plate 241 mounted on top of the digestion chamber 22. A drive motor 242 is mounted on the top plate 241, and a drive shaft 243 is mounted on the output end of the drive motor 242. A stirring plate 244 is mounted on the drive shaft 243. The rotation of the drive motor 242 drives the drive shaft 243 to rotate, which in turn drives the stirring plate 244 to rotate. The rotation of the stirring plate 244 stirs the grain in the digestion chamber 22, ensuring uniform heating and digestion of heavy metals, resulting in a better digestion effect on heavy metals.

[0029] Specifically, to facilitate the disassembly and assembly of the main cover 33, the cover disassembly and assembly mechanism 36 includes an elastic insertion part 361 installed on the main cover 33. The elastic insertion part 361 has a slot 362. A support block 363 is installed on the outer wall of the release tube 32. A locking block 364 is installed on the support block 363 and engages with the slot 362. By prying the elastic insertion part 361 outward and causing the locking block 364 to disengage from the slot 362, the main cover 33 can be pulled out directly.

[0030] The outer wall of the release tube 32 is equipped with a positioning slot 365, and the main cover 33 is equipped with a positioning plug 366, which is inserted into the positioning slot 365. When the positioning plug 366 is inserted into the positioning slot 365, the elastic insertion part 361 will contact the locking block 364. The elastic insertion part 361 will deform and open outward under the pressure of the locking block 364. When the locking slot 362 and the locking block 364 overlap, the elastic insertion part 361 will restore its deformation and lock the locking block 364 into the elastic insertion part 361, thus completing the installation of the main cover 33.

[0031] Specifically, to facilitate the disassembly and assembly of the secondary cover 35, the secondary cover disassembly and assembly mechanism 37 includes a retaining sleeve 371 installed on the secondary cover 35, a guide block 372 installed on the main cover 33, a locking rod 373 slidably installed inside the guide block 372, the end of the locking rod 373 being engaged in the retaining sleeve 371, and a spring 374 installed on the guide block 372 and the locking rod 373; by pulling the locking rod 373 outward and removing the end of the locking rod 373 from the retaining sleeve 371, the secondary cover 35 can be pulled out from the main cover 33.

[0032] A positioning block 375 is installed on the secondary cover 35, and a positioning sleeve 376 is installed on the main cover 33. The positioning block 375 is located inside the positioning sleeve 376. Pull the lever 373 outward and align the positioning block 375 with the positioning sleeve 376 and press it in. At this time, the secondary cover 35 enters the main cover 33. Then release the lever 373. Under the action of the spring 374, the lever 373 will be driven to engage with the sleeve 371, thus completing the installation of the secondary cover 35.

[0033] Furthermore, to improve the sealing performance of the main cover 33 and the secondary cover 35, a first sealing ring 38 is installed on the main cover 33, and a second sealing ring 39 is installed on the secondary cover 35. The first sealing ring 38, when inserted into the release tube 32, improves the sealing performance of the main cover 33, and the second sealing ring 39, when inserted into the main cover 33, improves the sealing performance of the secondary cover 35.

[0034] Furthermore, in order to collect the released waste liquid and grain, a No. 1 collection box 4 and a No. 2 collection box 5 are set on the bottom plate 1. A positioning block 6 is installed on the bottom plate 1. The No. 1 collection box 4 and the No. 2 collection box 5 can collect the released waste liquid and grain respectively. The positioning block 6 can play a role in positioning the No. 1 collection box 4 and the No. 2 collection box 5.

[0035] Working principle: During use, grains with excessive heavy metals are placed in the digestion chamber 22 via 245, and digestion solution is poured in simultaneously. The heating temperature of the heating inner liner 23 is adjusted by the thermostat 25, and the heating inner liner 23 heats the digestion solution to digest the heavy metals in the grains. The rotation of the drive motor 242 drives the drive shaft 243 to rotate, which in turn drives the stirring plate 244 to rotate. The rotation of the stirring plate 244 stirs the grains in the digestion chamber 22, ensuring that the grains are heated evenly to digest the heavy metals, resulting in a good digestion effect. After the heavy metals digestion is complete, the lever 373 is pulled outward, and the end of the lever 373 is pulled out of the sleeve 371. Then, the secondary cover 35 is pulled out from the main cover 33. The filter screen 34 filters the digested grains, and the waste liquid after digestion is released through the filter screen 34. At this time, the waste liquid is collected by the first collection box 4 placed at the bottom of the digestion chamber 22. Then, pry the elastic connector 361 outwards so that the locking block 364 is no longer locked in the locking slot 362, and then pull out the main cover 33 directly. Place the second collection box 5 at the bottom of the digestion chamber 22 in advance. At this time, the grain that has been digested for heavy metals will be released into the second collection box 5 through the release pipe 32, which makes it convenient to collect the grain and digestion waste liquid separately.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
