Description

Technical Field

[0001] This utility model relates to the field of drug residue detection technology, and in particular to a rapid homogenization device for pretreatment of drug residues in aquatic product muscle tissue. Background Technology

[0002] With the continuous growth of international trade in aquatic products and increasingly stringent domestic and international food safety regulations, drug residue testing has become a core aspect of aquatic product quality and safety monitoring. In drug residue testing of aquatic products, sample pretreatment typically involves pulverizing, mixing, and homogenizing the muscle tissue of fish, shrimp, and other seafood to ensure the accuracy of subsequent extraction and testing data.

[0003] However, existing muscle tissue homogenization equipment generally lacks an effective adjustment mechanism, making it impossible to flexibly adjust the position of the homogenizer in the mixing tank according to usage requirements. This makes it difficult for the device to fully break down and uniformly mix samples at different depths in the mixing tank. At the same time, some equipment still relies on ordinary grinding tools or manual chopping for processing, which is not only inefficient and time-consuming, but also the homogenization effect is greatly affected by the operator's experience, which can easily lead to insufficient tissue breakdown and uneven mixing, resulting in fluctuations in drug residue extraction rate and affecting the stability and repeatability of test results.

[0004] Therefore, existing technologies still have limitations in practical use, such as simple structure, insufficient adjustment capability, and low homogenization reliability, which urgently need further improvement. Based on this, we propose a rapid homogenization device for pretreatment of drug residues in aquatic product muscle tissue. Utility Model Content

[0005] 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 the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a rapid homogenization device for pretreatment of drug residues in aquatic product muscle tissue, which can solve the problems of insufficient adjustment capability of existing homogenization equipment, inability to fully crush and mix samples at different depths, low efficiency of manual grinding, poor homogenization consistency leading to unstable drug residue extraction rate.

[0007] To solve the above technical problems, this utility model provides a rapid homogenization device for pretreatment of drug residues in aquatic product muscle tissue, which adopts the following technical solution: it includes a metal support, an electrical control box installed on one side of the metal support, a pulverizing and homogenizing component installed on the top of the metal support, a mixing tank also provided on one side of the metal support, a number of support legs provided at the bottom of the mixing tank, universal wheels connected to the bottom of the support legs and the bottom of the metal support, and a discharge valve also provided on one side of the bottom of the mixing tank; The pulverizing and homogenizing assembly includes a transmission housing. Both ends of the transmission housing are rotatably connected to transmission wheels via bearings. A transmission belt connects the two sets of transmission wheels. A first motor is installed at the bottom of one set of transmission wheels, and a pulverizing and homogenizing device is installed at the bottom of the other set of transmission wheels.

[0008] Optionally, the pulverizer includes a drive shaft, one end of which is equipped with a grinding wheel, and the other end of the drive shaft away from the grinding wheel is fixedly connected to a transmission disc. A mixing rod is also installed on one side of the transmission disc.

[0009] Optionally, two sets of stop bars are connected to one side of the metal bracket, and a positioning clamp is provided at one end of each set of stop bars. A guide plate is installed on the top of the metal bracket, and a guide sleeve is connected to the bottom of one end of the guide plate. A first guide groove is opened on one side of the guide plate, and a second guide groove is opened on both sides of the guide plate near the first guide groove.

[0010] Optionally, the metal bracket is provided with a lifting adjustment component, which includes a supporting top plate. Two sets of guide arm plates are connected to the bottom of the supporting top plate. A guide slide rod is connected to the side of the supporting top plate near the guide arm plates. A supporting frame is connected between the ends of the two sets of guide arm plates near the supporting top plate. A supporting bottom plate is also installed between the ends of the two sets of guide arm plates away from the supporting top plate.

[0011] Optionally, the guide arm plate is matched with the second guide groove structure, and the guide slide rod and the guide sleeve are in sliding fit.

[0012] Optionally, two sets of bearing seats are installed on the top of the support frame, and a linkage rod is connected between the two sets of bearing seats. A second motor is provided on one side of the support frame, and the output end of the second motor is connected to the linkage rod for transmission. A sprocket is installed in the middle of the linkage rod, and a chain is also provided between the sprocket and the support base plate.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. In this utility model, the first motor is controlled by the electrical control box to drive the transmission wheel and transmission belt, which drives the pulverizer to rotate at high speed. The pulverizing wheel can shear and break down muscle tissue fibers, while the mixing rod can generate a vortex effect through synchronous rotation, which can achieve efficient sample crushing and thorough solvent mixing. This not only significantly improves the processing speed, but also reduces the impact of operational errors on the homogenization effect, while ensuring the uniformity of sample pretreatment and the accuracy of drug residue detection results.

[0014] 2. In this utility model, the linkage rod is driven to rotate by the second motor, so that the sprocket pulls the chain to move up and down precisely along the first guide groove, driving the support frame, guide arm plate and support top plate to move synchronously. Combined with the double-sided sliding cooperation between the guide arm plate and the second guide groove, and the guide slide rod and the guide sleeve, the crushing and homogenizing component can be smoothly adjusted in the vertical direction, and the working depth of the crushing and homogenizing device in the mixing tank can be flexibly controlled. This allows for the layer-by-layer crushing and dynamic mixing of the bottom, middle and top samples, effectively avoiding dead corners, significantly enhancing the stability of drug residue extraction rate and improving the repeatability of test results.

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.

[0019] Example: Refer to Figures 1 to 8This utility model provides an embodiment of a rapid homogenization device for pretreatment of drug residues in aquatic product muscle tissue. It includes a metal support 1, an electrical control box 2 mounted on one side of the metal support 1, a pulverizing and homogenizing assembly 3 mounted on the top of the metal support 1, a mixing tank 4 also mounted on one side of the metal support 1, several sets of support legs 41 mounted on the bottom of the mixing tank 4, and casters 42 connected to the bottom of the metal support 1 for each support leg 41. A discharge valve 43 is also provided on one side of the bottom of the mixing tank 4. The pulverizing and homogenizing assembly 3 includes a transmission housing 31, with its internal ends divided into... A transmission wheel 32 is rotatably connected via a bearing, and a transmission belt 33 connects the two sets of transmission wheels 32. A first motor 34 is mounted at the bottom of one set of transmission wheels 32, and a homogenizer 35 is mounted at the bottom of the other set of transmission wheels 32. This aquatic product muscle tissue homogenizing device, through the coordinated use of the transmission housing 31, transmission wheels 32, transmission belt 33, first motor 34, and homogenizer 35, effectively transmits the power output from the first motor 34 to the homogenizer 35, achieving high-speed rotation. The rotational motion of the homogenizer 35 allows for the homogenization of the aquatic product muscle tissue. The product's muscle tissue is sheared, crushed, and mixed to ensure uniform fragmentation of the sample tissue and thorough mixing with the solvent, achieving efficient dissolution of drug residues, improving sample pretreatment efficiency and homogenization quality, and ensuring the accuracy and repeatability of subsequent test results. The homogenizer 35 includes a drive shaft 351, with a grinding wheel 352 mounted at one end of the drive shaft 351. A drive disc 353 is fixedly connected to the end of the drive shaft 351 away from the grinding wheel 352. A mixing rod 354 is also mounted on one side of the drive disc 353. This homogenizer 35, through transmission... The coordinated use of the moving shaft 351, the agitator 352, the transmission disc 353, and the mixing rod 354 can effectively transmit power from the transmission system to each functional component. The agitator 352 shears and breaks down the muscle tissue of aquatic products, rapidly decomposing dense muscle blocks and achieving efficient sample pulverization. The transmission disc 353 drives the mixing rod 354 to rotate synchronously, generating a vortex effect that fully mixes the broken tissue with the solvent, achieving efficient dissolution of drug residues, thereby ensuring the uniformity of sample pretreatment and the accuracy of test results.

[0020] Two sets of stop bars 11 are connected to one side of the metal bracket 1. Each set of stop bars 11 has a positioning clamp 12 at one end. A guide plate 13 is installed on the top of the metal bracket 1. A guide sleeve 14 is connected to the bottom of one end of the guide plate 13. A first guide groove 15 is formed on one side of the guide plate 13, and second guide grooves 16 are formed on both sides of the guide plate 13 near the first guide groove 15. Through the two sets of stop bars 11 connected to one side of the metal bracket 1, and the positioning clamp 12 at one end of the stop bars 11, the mixing tank 4 placed on one side of the metal bracket 1 can be stably positioned, achieving radial positioning and stable support of the sample during the homogenization process. Through the installation of the guide plate 13 and the guide sleeve 14 connected to its bottom, a reliable vertical guide can be provided for the lifting and adjusting component 17, enabling the crushing and homogenizing assembly 3 to rise and fall smoothly along a predetermined trajectory. The lifting and adjusting component 17 is installed inside the metal bracket 1. The lifting and adjusting component 17 includes a support plate 171. Two sets of guide arm plates 172 are connected to the bottom of 71. A guide slide rod 173 is connected to the side of the support top plate 171 near the guide arm plate 172. A support frame 174 is connected between the ends of the two sets of guide arm plates 172 near the support top plate 171. A support bottom plate 175 is also installed between the ends of the two sets of guide arm plates 172 away from the support top plate 171. The support top plate 171 and the two sets of guide arm plates 172 connected to its bottom can constrain the component to move smoothly along the guide path, achieving stable support during the lifting process. The guide slide rod 173 connected to one side of the support top plate 171 can slide and cooperate with the guide sleeve 14 to ensure vertical lifting without deviation. The support frame 174 and the support bottom plate 175 connected to one end of the two sets of support top plates 171 can form a complete support structure, so that the crushing and homogenizing component 3 is subjected to balanced force and moves smoothly during the lifting process, ensuring that the crushing and homogenizing device 35 can be accurately positioned in the mixing tank 4 and effectively process samples of different depths.

[0021] The guide arm plate 172 is structurally matched with the second guide groove 16, and the guide slide rod 173 is slidably engaged with the guide sleeve 14. Through the structural matching of the guide arm plate 172 and the second guide groove 16, the movement path of the pulverizing and homogenizing component 3 can be limited, enabling the pulverizing and homogenizing component 3 to move smoothly along a predetermined trajectory during lifting and lowering. Through the sliding engagement of the guide slide rod 173 with the guide groove and guide sleeve 14, frictional resistance can be reduced and vertical movement constrained, achieving smooth lifting and precise positioning of the lifting and adjusting component 17. This ensures that the pulverizing and homogenizing device 35 can be safely and stably adjusted in depth within the mixing tank 4, facilitating thorough crushing and mixing of samples at different levels. Two sets of bearing seats 1741 are installed on the top of the support frame 174, and a linkage rod 1742 connects the two sets of bearing seats 1741. A second motor 1743 is installed on one side of the support frame 174, and the output end of the second motor 1743 is connected to… The linkage rods 1742 are connected by a transmission mechanism. A sprocket 1744 is installed in the middle of the linkage rod 1742. A chain 1745 is also provided between the sprocket 1744 and the support base plate 175. The chain 1745 matches the structure of the first guide groove 15. The chain 1745 and the sprocket 1744 are meshed. Through the two sets of bearing seats 1741 installed on the top of the support frame 174, the rotating bearing of the linkage rod 1742 can be supported and stabilized, so as to realize the smooth operation of the transmission system. Through the transmission connection between the linkage rod 1742 and the second motor 1743, the power of the second motor 1743 can be transmitted to the sprocket 1744 to realize the driving of the lifting action. Through the meshing of the chain 1745 between the sprocket 1744 and the support base plate 175 and the matching of the structure of the first guide groove 15, the rotational motion can be converted into the vertical displacement of the support frame 174, so as to realize the precise lifting and height adjustment of the crushing and homogenizing component 3.

[0022] Working Principle: The aquatic product muscle tissue homogenization device designed in this scheme, through a highly integrated mechanical transmission system and intelligent lifting and adjusting mechanism, can realize automated and depth-adjustable homogenization processing of aquatic product muscle tissue. In use, the sample to be tested and the extraction solvent are first placed in the mixing tank 4, and the mixing tank 4 is fixed by the positioning clamp 12 to ensure stable processing. After starting the electrical control box 2, the first motor 34 drives the transmission wheel 32 to rotate. The transmission wheel 32 drives the homogenizer 35 to rotate at high speed through the transmission belt 33, realizing the initial mechanical action on the sample. 5 is composed of a drive shaft 351, a grinding wheel 352, a transmission disc 353, and a mixing rod 354. The grinding wheel 352 can shear and break down muscle tissue fibers, rapidly decomposing dense muscle blocks. The mixing rod 354 on the side of the transmission disc 353 generates a vortex effect during synchronous rotation, which can fully mix the broken tissue with the solvent, achieving efficient dissolution of drug residues, thereby ensuring the uniformity of sample pretreatment and the accuracy of test results. This structural design allows grinding and mixing to be carried out simultaneously, improving the processing speed and reducing the impact of operational errors on the homogenization effect.

[0023] The core innovation lies in the lifting and adjusting component 17: the second motor 1743 drives the linkage rod 1742 to rotate, causing the sprocket 1744 to pull the chain 1745 to move up and down precisely along the first guide groove 15, driving the support frame 174, guide arm plate 172 and support top plate 171 to move synchronously. The guide arm plate 172 and the second guide groove 16, and the guide slide rod 173 and the guide sleeve 14 form a double-sided sliding fit to ensure that the crushing and homogenizing component 3 is smoothly adjusted in the vertical direction without deviation or shaking. The operator can flexibly adjust the depth of the crushing and homogenizing device 35 in the mixing tank 4 according to the sample volume and tissue characteristics to achieve layer-by-layer crushing and dynamic mixing of the bottom, middle and top samples, avoiding dead corners. After processing, the homogenate is quickly collected through the discharge valve 43. The universal wheel 42 is designed to facilitate the overall movement and positioning of the device, adapting to different experimental environments and operational needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
