Description

Technical Field

[0001] This utility model relates to the field of meat product testing technology, specifically to a heavy metal detection device for fresh meat. Background Technology

[0002] Heavy metals, as discussed in terms of environmental pollution, mainly refer to metals or metalloids such as mercury, cadmium, lead, chromium, and arsenic. The harmful effects of heavy metals will be discussed from several aspects, including their naturalness, toxicity, activity and persistence, biodegradability, bioaccumulation, and additive effects on organisms. Fresh meat refers to meat products made primarily from livestock and poultry. Heavy metal testing is required before fresh meat is sold.

[0003] In existing technologies, heavy metal detection in fresh meat involves first sampling and pulverizing the fresh meat, then digesting the pulverized meat, and finally removing the digested meat solution from the digestion device for heavy metal detection. Existing digestion methods generally include wet digestion and microwave digestion. Both methods require pulverizing the fresh meat to increase its surface area, promote contact between the digestion solution and the meat, and improve reaction efficiency. However, during digestion, the pulverized meat sample and digestion solution are placed directly in the digestion tank without dynamic mixing, resulting in uneven solid-liquid contact and low digestion efficiency.

[0004] Therefore, it is of great importance to design a heavy metal detection device for fresh meat to address the above-mentioned shortcomings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a heavy metal detection device for fresh meat. This device aims to solve the technical problem that in the current technology for heavy metal detection in fresh meat, the crushed meat sample and digestion solution are directly placed in the digestion tank, lacking a stirring and dynamic mixing method, resulting in uneven solid-liquid contact and low digestion efficiency.

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

[0007] A heavy metal detection device for fresh meat includes a digestion tank, a lid fixedly installed on the top of the digestion tank, a crushing component fixedly installed on the front end of the lid, a liquid addition pipe fixedly connected to the top of the lid and to the left of the crushing component, a stirring component installed on the inner side of the lid, and a collection box fixedly installed at the bottom of the digestion tank.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to 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.

[0025] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0026] A heavy metal detection device for fresh meat includes a digestion tank 1, a lid 2 fixedly installed on the top of the digestion tank 1, a crushing component 3 fixedly installed at the front end of the lid 2, a liquid addition pipe 4 fixedly connected to the top of the lid 2 and to the left of the crushing component 3, a stirring component 5 installed inside the lid 2, and a collection box 6 fixedly installed at the bottom of the digestion tank 1.

[0027] First, in this embodiment, the specific structure of the stirring assembly 5 is as follows:

[0028] The stirring assembly 5 includes a drive housing 501 fixedly installed at the center of the top of the digestion tank 1. A stirring shaft 502 is rotatably connected to the inner side of the housing cover 2. A transmission housing 503 is installed on the outer side of the stirring shaft 502, and the stirring shaft 502 is rotatably connected to the transmission housing 503. Both the left and right sides of the transmission housing 503 are fixedly connected to the inner wall of the digestion tank 1 via connecting rods 504. Tilting shafts 505 are rotatably connected to both the front and rear sides of the transmission housing 503. A drive gear 506 is fixedly installed inside the stirring shaft 502 and located inside the transmission housing 503. Both sets of tilting shafts 505 mesh with the drive gear 506 via transmission gears 507. When testing fresh meat for heavy metals, the fresh meat is crushed using the crushing component 3 and then introduced into the digestion tank 1. The top cover of the liquid addition pipe 4 is then opened to introduce the digestion solution into the digestion tank 1. The stirring shaft 502 is driven to rotate by the drive housing 501. Under the transmission of the drive gear 506 and the transmission gear 507, the two sets of turning shafts 505 rotate accordingly. The stirring shaft 502 stirs and mixes the crushed meat sample with the digestion solution, while the turning shafts 505 stir and mix the meat sample laterally, thereby improving the mixing effect, making the solid-liquid contact more uniform, and thus improving the digestion efficiency.

[0029] Furthermore, a first motor 508 is fixedly installed on the top of the drive housing 501, and the top end of the stirring shaft 502 is connected to the drive end of the first motor 508 through a pulley set 509. When the meat sample and digestion solution are stirred and mixed, the first motor 508 is started and the stirring shaft 502 is driven to rotate by the pulley set 509.

[0030] Then, a spiral stirring frame 510 is fixedly connected to the bottom end of the stirring shaft 502. Multiple sets of stirring crossbars 511 are fixedly connected to the outside of the spiral stirring frame 510, and multiple sets of turning rods 512 are fixedly connected to the outside of the turning shaft 505. When the stirring shaft 502 rotates, the spiral stirring frame 510 is used to spirally stir the meat sample and digestion liquid, and the stirring range is increased by the multiple sets of stirring crossbars 511. When the turning shaft 505 rotates, the multiple sets of turning rods 512 are used to horizontally stir and mix the meat sample, thereby turning the meat sample, which can improve the stirring and mixing effect, make the solid-liquid contact more uniform, and thus improve the digestion efficiency.

[0031] Furthermore, the digestion tank 1 has a mixing zone 101 and a digestion zone 102 at its upper and lower ends, respectively. A discharge baffle 103 is fixedly connected inside the digestion tank 1 between the mixing zone 101 and the digestion zone 102. A discharge blade 104 is fixedly installed at the bottom of the stirring shaft 502 inside the discharge baffle 103. The meat sample and the digestion liquid are stirred and mixed inside the mixing zone 101. At the same time, when the meat sample and the digestion liquid are stirred and mixed, the discharge blade 104 is used to slowly guide the meat sample into the digestion zone 102 for full digestion.

[0032] The outer side of the lid 2 is fixedly connected to the digestion vessel 1 by multiple sets of latches 201. A rubber sealing ring 202 is installed at the connection between the top of the digestion vessel 1 and the lid 2. The lid 2 is fixedly installed on the top of the digestion vessel 1 by multiple sets of latches 201, and the rubber sealing ring 202 ensures the sealing after closing, while also facilitating the opening of the lid 2 for cleaning and maintenance of the interior.

[0033] Secondly, the crushing assembly 3 includes a crushing box 301 fixedly installed at the front end of the top of the box cover 2. A crushing shaft 302 is rotatably connected inside the crushing box 301. A second motor 303 is fixedly installed on the back of the crushing box 301, and the drive end of the second motor 303 is fixedly connected to the rear end of the crushing shaft 302. A crushing groove 304 is formed on the inner side wall of the crushing box 301 between the crushing shaft 302 and the crushing shaft 302. A crushing blade 305 is fixedly installed at the front end of the crushing shaft 302. A guide pipe 306 is fixedly installed between the crushing box 301 and the box cover 2. A [missing information - likely a device or component] is installed between the crushing box 301 and the guide pipe 306. When fresh meat samples are put into the digestion tank 1 through the sieve plate 307, they are fed in from the opening at the top of the crushing box 301. The second motor 303 drives the crushing shaft 302 to rotate. The minced meat is crushed between the crushing shaft 302 and the crushing tank 304, and the crushing blade 305 further improves the crushing effect. Finally, the meat sample that reaches the required size is fed into the digestion tank 1 through the feed pipe 306 after passing through the sieve plate 307. This ensures the uniformity of the size of the meat sample. The crushed meat sample can fully contact the digestion liquid, shorten the reaction time, and further improve the digestion efficiency.

[0034] Finally, a discharge pipe 601 is fixedly installed between the collection box 6 and the digestion tank 1. A first valve 602 is installed between the discharge pipe 601 and the collection box 6. A liquid sampling pipe 603 is fixedly connected to the bottom of the collection box 6, and a second valve 604 is installed on the liquid sampling pipe 603. After the meat sample reacts and digests with the digestion solution, the first valve 602 is opened to introduce the liquid into the interior of the collection box 6, and the second valve 604 on the liquid sampling pipe 603 is opened for sampling and testing.

[0035] In this embodiment, the specific implementation scenario is as follows: When testing fresh meat for heavy metals, the fresh meat sample is placed into the digestion tank 1 through the opening at the top of the grinding chamber 301. The second motor 303 drives the grinding shaft 302 to rotate, and the minced meat is crushed between the grinding shaft 302 and the grinding tank 304. The grinding blades 305 further improve the crushing effect. Finally, the meat sample that reaches the required size passes through the sieve plate 307 and is introduced into the digestion tank 1 through the feed pipe 306, thus ensuring the uniformity of the meat sample size. The crushed meat sample can fully contact the digestion liquid. Then, the cap at the top of the liquid addition pipe 4 is opened to introduce the digestion liquid into the digestion tank 1. The drive housing 501 drives the stirring shaft 502 to rotate, and the drive gear 506 and the transmission gear 507 drive the two sets of turning shafts 505. The mixing shaft 502 stirs and mixes the pulverized meat sample with the digestion solution, while the turning shaft 505 stirs and mixes the meat sample laterally, turning it over. The meat sample and digestion solution are stirred and mixed inside the mixing zone 101. At the same time, the discharge blades 104 slowly guide the meat sample into the digestion zone 102 for full digestion. After the meat sample and digestion solution have reacted and digested, the first valve 602 is opened to guide the liquid into the collection tank 6, and the second valve 604 on the liquid sampling pipe 603 is opened for sampling and testing. The whole operation process is simple and convenient. This utility model improves the stirring and mixing effect through design, making the solid-liquid contact more uniform, and ensuring the uniformity of meat sample size. By allowing the pulverized meat sample to fully contact the digestion solution, the reaction time is shortened, thereby improving the digestion efficiency.
