Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a device for detecting zearalenone. Background Technology

[0002] Food testing is crucial for food safety and serves as a vital line of defense for public health, aiming to accurately identify harmful substances and components in various foods. Zearalenone, a mycotoxin produced by Fusarium, is widely found in moldy grains and possesses strong toxicity, particularly harmful to the reproductive system of animals. Zearalenone, its core structural component, also poses potential health risks. Detecting these two substances is a key part of food testing. Advanced detection technologies can accurately determine the content of zearalenone and zearalenone in food, assessing its safety and providing strong evidence for food safety supervision, effectively ensuring the safety of food consumed by consumers.

[0003] The detection process for zearalenone involves various equipment, such as grinders, centrifuges, nitrogen blowers, and mycotoxin detectors. Centrifugation in zearalenone detection achieves liquid-solid separation through high-speed rotation, enriching the target analyte and facilitating accurate subsequent determination. Before centrifugation, the sample needs to be balanced to ensure uniform force on the centrifuge drum. Otherwise, uneven force during centrifugation will cause severe vibration, accelerating component wear and potentially leading to explosion, endangering equipment and personnel safety. Current technologies often use alignment balancing, equilateral triangle balancing, or a combination of alignment and equilateral triangle balancing. While these methods are effective for centrifuge balancing, they require highly experienced and skilled operators. Since centrifuges do not provide direct indication of balancing orifice positions, manual balancing is inefficient and prone to errors, leading to inaccurate balancing, equipment malfunction, and damage.

[0004] Therefore, there is an urgent need to provide a device for detecting zearalenone in zearalenone to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for detecting zearalenone.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a device for detecting zearalenone, including a housing mechanism and an indicating mechanism, wherein a driving mechanism is fixed inside the housing mechanism, a centrifugal mechanism is meshed on the driving mechanism, and an indicating mechanism is also fixed inside the housing mechanism.

[0007] A lighting mechanism is attached to the indicator mechanism;

[0008] The housing mechanism is also fixed with a control mechanism for human-computer interaction and calculation of the balancing hole position.

[0009] The present invention is further configured such that: the housing mechanism includes a housing body, an electromechanical compartment is provided inside the housing body, a motor frame is fixed at the bottom of the electromechanical compartment, a centrifugal chamber is also provided inside the housing body, a bearing is fixed at the bottom of the centrifugal chamber, and a housing cover is hinged to the top of the housing body.

[0010] With the above technical solution, the bottom ends of the electromechanical compartment and the centrifuge compartment are connected, the bearing is fixed by the upright, the upright is fixed to the outer ring of the bearing, the inner ring of the bearing can rotate freely, and the shell cover can be locked when closed.

[0011] The present invention is further configured such that: the driving mechanism includes a speed-regulating motor fixed on a motor frame, a large pulley is fixed at the output end of the speed-regulating motor, and a transmission belt is engaged on the large pulley.

[0012] Through the above technical solution, the speed of the speed-regulating motor can be adjusted. When the speed-regulating motor starts, it can drive the large pulley and the transmission belt to rotate.

[0013] The present invention is further configured such that: the centrifugal mechanism includes a small pulley meshing with the other end of the transmission belt, a rotating shaft is fixed to the top of the small pulley, a centrifugal disc is fixed to the top of the rotating shaft, a plurality of tube holes are opened at the top of the centrifugal disc, and a dividing line and an indicator arrow are sprayed on the top of the centrifugal disc.

[0014] With the above technical solution, the tube holes are arranged in a ring-shaped equidistant array, and centrifuge tubes can be inserted into the tube holes. When the transmission belt rotates, the small pulley will be driven to rotate. The large pulley, transmission belt and small pulley effectively increase the output speed of the speed regulating motor. When the small pulley rotates, the shaft and centrifuge disc will also rotate, thereby centrifuging the test liquid in the centrifuge tube.

[0015] The present invention is further configured such that: the indicating mechanism includes an indicating disc fixed to the inner wall of the centrifuge chamber, a plurality of partition plates are fixed to the bottom end of the indicating disc, a plurality of frosted glass plates are also embedded in the indicating disc, a protective cover is fixed to the bottom end of the indicating disc, and a plurality of buckles are fixed to the protective cover.

[0016] With the above technical solution, the number of frosted glass plates is the same as the number of tube holes, and the frosted glass plates are also arranged in a ring-shaped equidistant array with the tips of the frosted glass plates pointing to the center of the array. The separator plates separate each frosted glass plate from the bottom. The protective cover is cylindrical, and both the indicator plate and the protective cover are made of metal. When the centrifuge explodes, the protective cover can play a shielding role, thereby effectively reducing the damage to the casing and components.

[0017] The present invention is further configured such that: the lighting mechanism includes an annular light plate snapped onto a buckle, the inner side of the annular light plate has multiple slots, and the top of the annular light plate is fixed with multiple LED lights.

[0018] Through the above technical solution, the ring light panel is fixed to the protective cover by the slot and the buckle. The number of LED lights is the same as the number of frosted glass sheets, and the bottom of the LED lights and the frosted glass sheets are aligned. Each LED light can be powered independently. When the LED light is powered on, its light will pass through the corresponding frosted glass sheet, causing the frosted glass sheet to emit light. The separator can effectively prevent the light from the LED light from shining on the other frosted glass sheets.

[0019] The present invention is further configured such that: the control mechanism includes a cover fixed to the top of the housing body, an interactive screen is embedded in the top of the cover, a control panel is also fixed to the top of the cover, and a control circuit board is fixed to the bottom of the cover.

[0020] Through the above technical solution, the speed-regulating motor and LED lights are electrically connected to the control circuit board. The control circuit board integrates a processing chip, a PLC chip, a speed regulation circuit, and a time control circuit. The operator can interact with the device through the interactive screen and control panel to set the centrifugation speed and centrifugation time. When the operator needs to centrifuge the sample in the centrifuge tube, they can first manually rotate the centrifuge disc to align the indicator arrow with any of the frosted glass slides. Then, they can input the number of centrifuge tubes through the control panel. The processing chip automatically calculates the position where the centrifuge tubes need to be inserted based on the number of centrifuge tubes and lights up the corresponding LED light. After the corresponding LED light is lit, the corresponding frosted glass slide will light up. At this time, the operator can insert the centrifuge tube into the tube hole pointed to by the lit frosted glass slide to achieve balancing. The dividing line can effectively divide the sector of each tube hole, thereby preventing the operator from misreading the position pointed to by the lit frosted glass slide.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting up a driving mechanism, a centrifugal mechanism, an indicating mechanism, a lighting mechanism, and a control mechanism, this utility model enables the device to automatically calculate the balancing hole positions and provide lighting indication, thereby improving the ease of operation and effectively avoiding balancing errors.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-6A device for detecting zearalenone includes a housing mechanism 1 and an indicating mechanism 4. The housing mechanism 1 includes a housing body 101, an electromechanical chamber 102 disposed inside the housing body 101, a motor frame 103 fixed to the bottom of the electromechanical chamber 102, a centrifuge chamber 104 disposed inside the housing body 101, a bearing 105 fixed to the bottom of the centrifuge chamber 104, and a housing cover 106 hinged to the top of the housing body 101. The bottom ends of the electromechanical chamber 102 and the centrifuge chamber 104 are connected, and the bearing 105 is connected via... The stand is fixed and is fixed to the outer ring of the bearing 105. The inner ring of the bearing 105 can rotate freely. The cover 106 can be locked when closed. The drive mechanism 2 is fixed inside the housing mechanism 1. The drive mechanism 2 includes a speed-regulating motor 201 fixed on the motor frame 103. A large pulley 202 is fixed to the output end of the speed-regulating motor 201. A transmission belt 203 is engaged on the large pulley 202. The speed of the speed-regulating motor 201 is adjustable. When the speed-regulating motor 201 is started, it can drive the large pulley 202 and the transmission belt 203 to rotate.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, a centrifugal mechanism 3 is meshed with the drive mechanism 2. The centrifugal mechanism 3 includes a small pulley 301 meshing with the other end of the transmission belt 203. A rotating shaft 302 is fixed to the top of the small pulley 301, and a centrifugal disc 303 is fixed to the top of the rotating shaft 302. Multiple tube holes 304 are opened at the top of the centrifugal disc 303. A dividing line 305 and an indicator arrow 306 are also sprayed on the top of the centrifugal disc 303. The tube holes 304 are arranged in a ring-shaped equidistant array, and centrifugal tubes can be inserted into the tube holes 304. When the transmission belt 203 rotates, the small pulley 301 will be driven to rotate. The large pulley 202, the transmission belt 203, and the small pulley 301 effectively increase the output speed of the speed regulating motor 201. When the small pulley 301 rotates, the rotating shaft 302 and the centrifugal disc 303 will also rotate, thereby centrifuging the test liquid in the centrifugal tube. The inner side of the housing mechanism 1 An indicator mechanism 4 is also fixed, which includes an indicator disk 401 fixed to the inner wall of the centrifuge chamber 104. Multiple separators 402 are fixed to the bottom of the indicator disk 401. Multiple frosted glass plates 403 are also embedded in the indicator disk 401. A protective cover 404 is also fixed to the bottom of the indicator disk 401. Multiple buckles 405 are fixed to the protective cover 404. The number of frosted glass plates 403 is the same as the number of tube holes 304. The frosted glass plates 403 are also arranged in a ring-shaped equidistant array. The tips of the frosted glass plates 403 point to the center of the array. The separators 402 separate each frosted glass plate 403 from the bottom. The protective cover 404 is cylindrical. Both the indicator disk 401 and the protective cover 404 are made of metal. When the centrifuge explodes, the protective cover 404 can play a shielding role, thereby effectively reducing the damage to the casing and components.

[0034] like Figure 1 andFigure 5 As shown, a lighting mechanism 5 is snapped onto the indicator mechanism 4. The lighting mechanism 5 includes an annular light plate 501 snapped onto a buckle 405. Multiple slots 502 are provided on the inner side of the annular light plate 501. Multiple LED lights 503 are fixed to the top of the annular light plate 501. The annular light plate 501 is fixed to the protective cover 404 through the slots 502 and the buckle 405. The number of LED lights 503 is the same as the number of frosted glass sheets 403, and the bottom ends of the LED lights 503 and frosted glass sheets 403 are aligned. Each LED light 503 can be powered independently. When an LED light 503 is powered on, its light will pass through the corresponding frosted glass sheet 403, causing the frosted glass sheet 403 to emit light. The separator 402 can effectively prevent the light from the LED light 503 from shining on the other frosted glass sheets 403.

[0035] like Figure 1 and Figure 6 As shown, the housing mechanism 1 also has a control mechanism 6 fixed on it for human-machine interaction and calculating the balancing hole positions. The control mechanism 6 includes a cover 601 fixed to the top of the housing body 101, an interactive screen 602 embedded in the top of the cover 601, a control panel 603 fixed to the top of the cover 601, and a control circuit board 604 fixed to the bottom of the cover 601. The speed-regulating motor 201 and the LED light 503 are electrically connected to the control circuit board 604. The control circuit board 604 integrates a processing chip, a PLC chip, a speed regulation circuit, and a time control circuit. The operator can interact with the device through the interactive screen 602 and the control panel 603 to set the centrifugal speed and centrifugation time of the device. When centrifuging samples in centrifuge tubes, the centrifuge disc 303 can be manually rotated first to align the indicator arrow 306 with any of the frosted glass slides 403. Then, the number of centrifuge tubes is input through the control panel 603. The processing chip automatically calculates the required insertion position for balancing the centrifuge tubes based on the number of centrifuge tubes and illuminates the corresponding LED 503. After the corresponding LED 503 is illuminated, the corresponding frosted glass slide 403 will light up. At this time, the operator inserts the centrifuge tube into the tube hole 304 pointed to by the illuminated frosted glass slide 403 to achieve balancing. The dividing line 305 can effectively divide the sector of each tube hole 304, thereby preventing the operator from misreading the position pointed to by the illuminated frosted glass slide 403.

[0036] When using this invention, the operator first adjusts the position of the centrifuge tray 303, inputs the number of centrifuge tubes to be centrifuged through the control mechanism 6, and the indicator mechanism 4 automatically indicates the centrifuge tube balancing hole position. After inserting the sample solution centrifuge tube into the designated tube hole 304, the operator closes the shell cover 106 and turns on the centrifuge switch. The drive mechanism 2 then drives the centrifuge mechanism 3 to rotate and centrifuge the sample. After centrifugation, the operator can extract the sample supernatant from the centrifuge tube and soak the test strip. After incubating the test strip, it can be inserted into the fungal toxin detector for detection.
