Description

Technical Field

[0001] This utility model relates to the field of animal food detection technology, specifically a drug residue pretreatment device. Background Technology

[0002] Animal food drug residue pretreatment device is a set of equipment used for the pretreatment of animal food samples. Its core purpose is to efficiently and reliably extract, purify and concentrate trace amounts of veterinary drugs, hormones, antibiotics and other target residues from complex animal tissues such as muscle, liver, kidney, fat, milk, eggs and honey. The pretreatment device generally uses a pulverizing component to fully pulverize and mix the animal food sample with the extraction solvent to form a homogenate, which facilitates subsequent drug residue detection.

[0003] A pretreatment device for drug residues in animal-derived food disclosed in Chinese Patent Publication No. CN220854343U uses a sealed cover, a water tank, an inlet pipe, an inlet valve, a connecting pipe, a nozzle, an outlet pipe, and an outlet valve. The inlet pipe introduces water from an external water source into the water tank, which is then sprayed out through the connecting pipe and the nozzle to clean the stirring rod and the glass. The wastewater after cleaning is discharged through the outlet pipe and the outlet valve, preventing spillage during wastewater transfer and avoiding environmental pollution and adverse effects on the operator's health. However, the pretreatment device is not very effective and is not convenient for quickly and efficiently crushing and mixing animal-derived food. This results in poor overall uniformity of the mixed slurry, affecting the treatment effect and the accuracy of subsequent drug residue detection. Utility Model Content

[0004] The purpose of this invention is to provide a drug residue pretreatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drug residue pretreatment device, comprising a base, a processing cylinder disposed at the center of the left side of the upper surface of the base, a pulverizing blade disposed at the center of the interior of the processing cylinder, a fixing column fixedly connected to the center of the right side of the upper surface of the base, a lifting mechanism disposed at the top of the interior of the fixing column, a cylinder cover disposed on the right side of the lifting mechanism, scrapers fixedly connected to the left and right sides of the lower surface of the cylinder cover, a filter cylinder disposed inside the processing cylinder, and a rotating mechanism for rotating the processing cylinder and the pulverizing blade.

[0006] Preferably, a discharge port is fixedly connected to the bottom right side of the processing cylinder, and a feed port is fixedly connected to the left side of the upper surface of the rotating mechanism.

[0007] Preferably, the rotating mechanism includes a motor fixedly connected to the center of the base, a first gear mounted on the output shaft of the motor, a second gear meshing with the left side of the first gear, a limiting ring fixedly connected to the bottom of the processing cylinder that rotates within the base, toothed blocks fixedly connected at equal intervals around the inner side of the limiting ring, the left side of the toothed blocks being fixedly connected to the right side of the second gear, a first limiting block rotating within the bottom of the processing cylinder being concentrically fixed to the top of the first gear, and a second connecting block rotatably connected to the center of the lower surface of the cylinder cover.

[0008] Preferably, the first limiting block and the second connecting block have the same specifications, and the upper and lower ends of the crushing blade are provided with grooves that are adapted to the first limiting block and the second connecting block. The grooves are used for the insertion of the first limiting block, the second connecting block and the crushing blade.

[0009] Preferably, the lifting mechanism includes a servo motor fixedly connected to the center position inside the fixed column, a threaded rod installed on the output shaft end of the servo motor, a threaded block connected to the external thread of the threaded rod, a fixed arm fixedly connected to the left side of the threaded block, and the lower surface of the left side of the fixed arm fixedly connected to the cylinder cover.

[0010] Preferably, the lower surface of the filter cartridge is uniformly and circumferentially fixed with positioning rods at equal intervals, the positioning rods are inserted into the positioning groove at the bottom of the inside of the processing cartridge, and the upper surface of the filter cartridge is inserted into the lower surface of the cartridge cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This drug residue pretreatment device, with a motor installed inside the base, drives a first limiting block to rotate via a first gear. The first limiting block rotates within the pulverizing blades, rapidly pulverizing and mixing the animal food sample and extraction solvent. Simultaneously, the rotation of the first gear pushes the toothed block inside the limiting ring via the first limiting block, causing the limiting ring to rotate the top processing cylinder in the opposite direction. This, in turn, causes the internal filter cylinder to rotate synchronously, resulting in efficient and uniform crushing and mixing of the animal food sample. Furthermore, during the rotation of the processing cylinder, a scraper at the bottom of the cylinder cover rapidly scrapes the inner wall of the processing cylinder and the outer wall of the filter cylinder, effectively preventing material adhesion after mixing. This improves the overall functionality of the pretreatment device while ensuring uniform mixing, thus enhancing its overall effectiveness. Attached Figure Description

[0021] The rotating mechanism 3 includes a motor 301 fixedly connected to the center of the base 1. A first gear 302 is mounted on the output shaft of the motor 301. A second gear 303 is meshed with the left side of the first gear 302. A limiting ring 202 rotating inside the base 1 is fixedly connected to the bottom of the processing cylinder 2. Gear blocks 203 are circumferentially fixed at equal intervals on the inner side of the limiting ring 202. The left side of the gear blocks 203 is fixedly connected to the right side of the second gear 303. The top of the first gear 302 is concentrically fixed to a gear rotating inside the bottom of the processing cylinder 2. The first limiting block 304 is rotatably connected to the center of the lower surface of the cylinder cover 7, and the second connecting block 702 is rotatably connected to it. When the motor 301 starts, it can drive the first limiting block 304 to rotate through the first gear 302. At this time, the first limiting block 304 can drive the crushing blade 4 to rotate synchronously. At the same time, the first gear 302 pushes the second gear 303 on the left side to rotate, so that the second gear 303 can push the tooth block 203 on the bottom limiting ring 202 of the processing cylinder 2, and make the entire processing cylinder 2 rotate in the opposite direction to the crushing blade 4.

[0022] The first limiting block 304 and the second connecting block 702 have the same specifications. The upper and lower ends of the crushing blade 4 are provided with grooves that are compatible with the first limiting block 304 and the second connecting block 702. The grooves are used for the insertion of the first limiting block 304, the second connecting block 702 and the crushing blade 4.

[0023] The lifting mechanism 6 includes a servo motor 601 fixedly connected to the center of the fixed column 5. A threaded rod 602 is installed on the output shaft end of the servo motor 601. A threaded block 603 is connected to the external thread of the threaded rod 602. A fixed arm 604 is fixedly connected to the left side of the threaded block 603. The lower surface of the left side of the fixed arm 604 is fixedly connected to the cylinder cover 7. When the servo motor 601 is started, it can drive the threaded rod 602 to rotate. At this time, the threaded block 603 on the threaded rod 602 can move freely up and down on the threaded rod 602, and drive the cylinder cover 7 to move up and down through the fixed arm 604.

[0024] Positioning rods 901 are uniformly and circumferentially fixed to the lower surface of the filter cylinder 9. The positioning rods 901 are inserted into the positioning groove at the bottom of the inside of the processing cylinder 2. The upper surface of the filter cylinder 9 is inserted into the lower surface of the cylinder cover 7. When the positioning rods 901 at the bottom of the filter cylinder 9 are inserted into the bottom of the inside of the processing cylinder 2, the rotation of the processing cylinder 2 can drive the filter cylinder 9 to rotate synchronously. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0025] In this embodiment of the application, the servo motor 601 starts, driving the threaded rod 602 to rotate. At this time, the threaded block 603 on the threaded rod 602 can drive the cylinder cover 7 to cover the top of the processing cylinder 2 via the fixing arm 604. Animal food samples and extraction solvent can then be poured into the filter cartridge 9 inside the processing cylinder 2 through the feed inlet 701 on the cylinder cover 7. The motor 301 inside the base 1 starts, and the motor 301 drives the first limiting block 304 to rotate via the first gear 302. The first limiting block 304 then drives the pulverizing blade 4 to rotate synchronously. Simultaneously, the first gear 302 pushes the second gear 303 on the left side to rotate. The second gear 303 can push the toothed block 203 on the bottom limiting ring 202 of the processing cylinder 2, and make the entire processing cylinder 2 rotate in the opposite direction to the crushing blade 4. The crushing blade 4 can quickly crush the animal food sample in the filter cylinder 9 and mix it with the extraction solvent. The mixed slurry can overflow through the filter cylinder 9 and be discharged through the discharge port 201 on one side of the processing cylinder 2. At this time, the servo motor 601 reverses, and the fixed arm 604 can drive the cylinder cover 7 to be lifted. At the same time, the crushing blade 4 and the filter cylinder 9 can be removed from the processing cylinder 2, which is convenient for effective cleaning of the pretreatment device.
