Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dissolving equipment, and in particular to a dissolving device for food and drug testing. Background Technology
[0002] To ensure the safe and standardized use of food and drugs, specialized departments are needed to inspect them. Based on basic theories of physics, chemistry, and biochemistry, and various technologies, these departments inspect product quality according to established technical standards, such as international and national food and drug hygiene / safety standards, to ensure that the products meet quality standards.
[0003] Chinese utility model CN213221714U describes a food and drug testing dissolving device, which incorporates a vibration structure to prevent filter clogging and maintain filtration efficiency. The principle involves a protruding rod on the stirring rod, one end of which contacts a protrusion at the bottom of the filter screen, pushing the screen upwards. This, combined with a spring, causes the screen to vibrate up and down.
[0004] However, in existing devices, prolonged immersion of the spring in water can cause corrosion, affecting its elasticity. Additionally, sediment tends to adhere to the outside of the spring, making it unsuitable for use. Therefore, a dissolving device was designed to address these issues. Utility Model Content
[0005] The purpose of this invention is to provide a food and drug testing dissolving device to solve the problems mentioned in the background art.
[0006] The technical solution adopted in this utility model is: A food and drug testing dissolving device includes: a dissolving tank with a stirring rod penetrating its interior and rotatably connected to the stirring rod; a filter screen fitted onto the outside of the stirring rod; and a vibration assembly mounted on the dissolving tank, the vibration assembly including: a motor fixedly mounted on the dissolving tank, with its output shaft fixedly connected to the bottom end of the stirring rod; a turntable fixedly fitted onto the outer wall of the stirring rod; a protrusion fixedly mounted on the top of the turntable; a housing with its top end penetrating the bottom of the dissolving tank and fixedly connected to the dissolving tank; a vertical rod with its top end penetrating the housing and fixedly connected to the bottom of the filter screen; a ring fixedly fitted onto the outside of the vertical rod; and a spring fitted onto the outside of the vertical rod, with its two ends fixedly connected to the inner wall of the housing and the ring, respectively.

Therefore, they should not be construed as limitations on this utility model.
[0019] In current technology, the principle involves setting a protruding rod on the stirring rod, with one end of the protruding rod contacting a protrusion at the bottom of the filter screen to push the filter screen upwards. This, combined with a spring pulling the filter screen, achieves the purpose of up-and-down shaking. However, in existing devices, the springs are corroded and their elasticity is affected by prolonged immersion in water. Additionally, sediment easily adheres to the outside of the springs, making them unsuitable for use.
[0020] As shown in the attached figures, this utility model provides a food and drug testing dissolving device. The device includes: a dissolving tank 11 through which a stirring rod 12 passes and is rotatably connected; a filter screen 13 fitted on the outside of the stirring rod 12; and a vibration assembly 2 on the dissolving tank 11, the vibration assembly 2 including: a motor 21 fixedly mounted on the dissolving tank 11, with its output shaft fixedly connected to the bottom end of the stirring rod 12; a turntable 22 fixedly fitted on the outer wall of the stirring rod 12; a protrusion 23 fixedly mounted on the top of the turntable 22; a housing 24 whose top end passes through the bottom of the dissolving tank 11 and is fixedly connected to the dissolving tank 11; a vertical rod 25 whose top end passes through the housing 24 and is fixedly connected to the bottom of the filter screen 13; a ring 26 fixedly fitted on the outside of the vertical rod 25; and a spring 27 fitted on the outside of the vertical rod 25, with its two ends fixedly connected to the inner wall of the housing 24 and the ring 26, respectively.
[0021] Specifically, it mainly assesses the solubility and release characteristics of drug or food components by simulating the human digestive tract environment. Its core principles include: Dissolution medium simulation: The environment of human digestive fluid is simulated by using specific solvents (such as water, acid and alkali solutions), and the dissolution conditions are controlled by parameters such as temperature and rotation speed.
[0022] Mechanical stirring acceleration: Using stirring devices (such as motor-driven reciprocating mechanisms) to promote contact between solute and solvent, thereby improving dissolution efficiency and uniformity.
[0023] Automated sampling and analysis: Equipped with an automated sampling device, it periodically extracts the leachate and filters impurities to ensure the accuracy of test results.
[0024] In use, first place the solution and related items into the dissolving tank 11 (see the explanation above for the solution). Then connect the motor 21 to an external power source, which will drive the stirring rod 12 to rotate, stirring the internal solution and accelerating dissolution. Simultaneously, the turntable 22 rotates, causing the protrusion 23 to rotate as well. During rotation, the protrusion 23 contacts the bottom of the upright rod 25. Due to the inclined design of the protrusion 23, during rotation, it pushes the upright rod 25 through the housing 24, simultaneously causing the ring 26 to compress the spring 27. The upright rod 25 pushes the filter screen 13 upwards until the bottom of the upright rod 25 is displaced from the protrusion 23. Then, the spring 27 rebounds, pushing the upright rod 25 downwards, and the filter screen 13 follows suit. During the rotation of the turntable 22, the protrusion 23 repeatedly contacts the upright rod 25, causing the filter screen 13 to vibrate up and down, reducing the possibility of clogging. After dissolution to a certain extent, the drain pipe on one side of the dissolving tank 11 can be opened to drain and sample the internal liquid. During drainage, the filter screen 13 will filter out large particles of impurities.
[0025] In some embodiments, four bumps 23 are provided.
[0026] There are four settings that can increase the contact frequency, making the shaking effect better.
[0027] In some embodiments, the vibration assembly 2 further includes a ball bearing 251 disposed at the bottom of the upright 25.
[0028] The design of ball bearing 251 can reduce the friction between the bottom of the upright 25 and the turntable 22 and the protrusion 23.
[0029] In some embodiments, the vibration assembly 2 further includes a sealing ring 28 sleeved on the outside of the upright 25 and fixedly connected to the top of the housing 24.
[0030] The sealing ring 28 is designed to seal the contact area between the upright 25 and the housing 24, preventing liquid penetration.
[0031] In some embodiments, the vibration assembly 2 further includes a fan blade 29 fixedly disposed on the outer side wall of the stirring rod 12.
[0032] The design of fan blade 29 can agitate the liquid below filter screen 13 to prevent sedimentation.
[0033] In some embodiments, the dissolving tank 11 is provided with a protective component 3, which further includes: an arc-shaped plate 31 disposed on the bottom plate of the dissolving tank 11; an arc-shaped plate 32 slidably disposed inside the arc-shaped plate 31; a groove 33 formed at the top of the arc-shaped plate 31; and a slider 34 whose bottom end is inserted into the groove 33 and fixedly connected to the top end of the arc-shaped plate 32.
[0034] In use, simply pull the second arc plate 32 to rotate and extend it from inside the first arc plate 31. At the same time, the slider 34 slides inside the groove 33. The second arc plate 32 fits against one end of the first arc plate 31. The closure of the first arc plate 31 and the second arc plate 32 can protect the inner components.
[0035] In some embodiments, the protective component 3 further includes a magnetic plate 35 fixedly attached to one end of the first arc plate 31 and the second arc plate 32.
[0036] The design of the magnetic plate 35 allows one end of the curved plate 31 and the curved plate 32 to fit together better and not easily separate.
[0037] In some embodiments, the protective component 3 further includes a handle 36 fixedly disposed on the outer side wall of the arc-shaped plate 32.
[0038] The handle 36 is designed for easy gripping, thereby controlling the rotation of the curved plate 32.
[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
