Description

Technical Field

[0001] This utility model relates to the field of soybean milk production technology, specifically to a laser scattering monitoring instrument for foreign object detection. Background Technology

[0002] In the food processing industry, especially in the production of soy milk, foreign object detection is a key step in ensuring product quality and safety. Laser scattering detection technology has emerged in the field of foreign object detection due to its advantages such as high sensitivity and high precision. This technology can quickly and accurately detect tiny foreign objects, greatly improving detection efficiency and accuracy compared to traditional detection methods.

[0003] However, in practical applications, laser scattering monitors face many challenges. Among them, the cleanliness of the inner wall of the detection cylinder is particularly prominent. When materials such as soy milk flow through the detection cylinder, some of the material easily adheres to the inner wall. Over time, these deposits not only interfere with the subsequent emission of laser light and the reception of scattered light, leading to deviations in the detection results and reducing the accuracy and reliability of the detection, but also create favorable conditions for bacterial growth. The large-scale reproduction of bacteria not only affects product quality but may also cause food safety issues.

[0004] Currently, many laser scattering monitors on the market lack effective automatic cleaning mechanisms or only have simple cleaning functions, making it difficult to thoroughly remove stubborn deposits from the inner wall of the monitoring cylinder. This forces operators to perform frequent manual cleaning, which not only consumes a lot of time and manpower but also makes it difficult to guarantee the timeliness and comprehensiveness of cleaning. If cleaning is not timely, it will seriously affect the continuity of production and product quality. In addition, some existing cleaning methods may cause some damage to the internal structure of the monitor, further shortening the service life of the equipment and increasing the operating costs of enterprises. In view of this, there is an urgent need to develop a monitor with efficient foreign object detection and automatic cleaning functions to improve the safety and detection efficiency of soy milk production. Utility Model Content

[0005] The purpose of this invention is to provide a laser scattering monitor for foreign object detection. By setting up a cleaning mechanism, it solves the problem of soybean milk adhering to the inner wall of the monitoring cylinder affecting subsequent detection results and causing bacteria growth. Moreover, it eliminates the need for manual cleaning, saving manpower and time.

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

[0007] A laser scattering monitor for foreign object detection includes a base plate, a monitoring cylinder fixed above the base plate, a laser emitting module and several scattered light receiving modules installed on the inner wall of the monitoring cylinder, and a data processing and analysis module installed on the top surface of the base plate. The monitor also includes:

[0008] The cleaning mechanism is located inside the monitoring cylinder and is used to clean the inner wall of the monitoring cylinder. The cleaning mechanism includes a brush ring, several bristles fixed on the outer circumference of the brush ring, a pump body installed on the top surface of the base plate and used to supply cleaning fluid to the brush ring, and an electric cylinder installed on the top surface of the base plate and used to drive the brush ring to move up and down. Several atomizing nozzles connected to the inner cavity and used to spray cleaning fluid are installed on the upper and lower surfaces of the brush ring.

[0009] In a preferred embodiment, the thickness of the base plate is 2-6cm, and the bottom surface of the base plate is provided with anti-slip texture;

[0010] This feature gives the base plate of the laser scattering monitor for foreign object detection a certain thickness and anti-slip properties, thus improving stability.

[0011] In a preferred embodiment, the monitoring cylinder is fixed to the top surface of the base plate by a plurality of support legs, and the plurality of support legs are distributed in a ring with equal spacing.

[0012] In a preferred embodiment, a feed funnel communicating with its inner cavity is fixed on the top surface of the monitoring cylinder, and a discharge pipe communicating with its inner cavity is fixed on the bottom end of the monitoring cylinder. Solenoid valves are installed on the outer walls of both the discharge pipe and the feed funnel tube.

[0013] In a preferred embodiment, the bottom of the monitoring cylinder has a structure that is concave from all sides to the center, and the parts of the monitoring cylinder that contact the pipe body of the feed funnel and the discharge pipe are all provided with sealing rings.

[0014] In a preferred embodiment, the monitoring cylinder has a mounting hole near the left end of its circumferential inner wall. The laser emitting module is embedded in the mounting hole on the inner wall of the monitoring cylinder. The monitoring cylinder has several mounting slots near the right end of its circumferential inner wall. These mounting slots are arranged in groups of seven and vertically on the inner wall of the monitoring cylinder. The scattered light receiving module is embedded in the mounting slot on the same side of the inner wall of the monitoring cylinder.

[0015] These four features make the connection between the monitoring cylinder and the base plate more stable, allow soy milk to easily enter and exit the monitoring cylinder, and control the feeding and discharging through a solenoid valve. The bottom structure of the monitoring cylinder facilitates the discharge of soy milk, and the connection has good sealing to prevent leakage. The laser emitting module and the scattered light receiving module can be accurately installed on the inner wall of the monitoring cylinder to ensure the detection effect.

[0016] In a preferred embodiment, the brush ring is located inside the monitoring cylinder, and the surface of the brush bristles away from the brush ring is tightly fitted with the inner circumferential wall of the monitoring cylinder. The top surface of the monitoring cylinder is provided with a through hole and a through groove. The cleaning mechanism also includes an inlet pipe fixed to the top surface of the brush ring and connected to its inner cavity, and a through pipe tightly sleeved with the outlet end of the pump body and fixed to the outer wall of the monitoring cylinder by a number of fixing rods. A corrugated pipe that penetrates the through hole on the top surface of the monitoring cylinder is connected between the through pipe and the inlet pipe.

[0017] In a preferred embodiment, sealing rings are provided at the parts of the liquid inlet pipe that contact the pump body and the bellows, sealing rings are provided at the parts of the liquid inlet pipe that contact the bellows and the brush ring, and sealing rings are also provided at the parts of the brush ring that contact the atomizing nozzles.

[0018] In a preferred embodiment, the cylinder body of the electric cylinder is mounted on the top surface of the base plate, and the cleaning mechanism further includes a lifting rod fixed on the top surface of the brush ring and slidably inserted into the through groove on the top surface of the monitoring cylinder. The top end of the lifting rod extends above the monitoring cylinder, a connecting rod is fixed on the top surface of the lifting rod, and the piston rod of the electric cylinder is fixed on the bottom surface of the connecting rod.

[0019] These three features enable the cleaning mechanism to effectively clean the inner wall of the monitoring cylinder, and ensure that the cleaning fluid is smoothly delivered to the brush ring. They also ensure good sealing at all connections of the cleaning mechanism to prevent leakage of the cleaning fluid, and allow the electric cylinder to drive the brush ring to rise and fall via the connecting rod, thereby cleaning the inner wall of the monitoring cylinder and ensuring the cleaning effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model, through the setup of a base plate, a monitoring cylinder, a laser emitting module, a scattered light receiving module, a data processing and analysis module, and a cleaning mechanism, achieves the function of detecting foreign objects in the soy milk entering the monitoring cylinder. At the same time, it can clean the inner wall of the monitoring cylinder. The brush ring, brush bristles, pump body, electric cylinder, and atomizing nozzle in the cleaning mechanism work together. During the process of the electric cylinder driving the brush ring to rise and fall, the brush bristles physically scrub the inner wall of the monitoring cylinder, and the atomizing nozzle sprays cleaning liquid for chemical cleaning. This effectively removes the soy milk material adhering to the inner wall of the monitoring cylinder, achieving the effect of preventing soy milk from adhering and affecting the detection results and avoiding bacterial growth. Moreover, no manual cleaning is required, saving manpower and time costs.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Please see Figure 1 The present invention provides a technical solution: a laser scattering monitoring instrument for foreign object detection, including a base plate 1, a monitoring cylinder 2 fixed above the base plate 1, a laser emitting module 3 and several scattered light receiving modules 4 installed on the inner wall of the monitoring cylinder 2, and a data processing and analysis module 11 installed on the top surface of the base plate 1.

[0031] The thickness of the base plate 1 is 2-6cm, and the bottom surface of the base plate 1 is provided with anti-slip texture;

[0032] The thickness of the base plate 1 is preferably 5cm, so that the base plate has sufficient strength to support the instrument. The anti-slip texture increases the friction with the placement surface, ensuring that the monitor is placed stably during operation and avoiding the impact of shaking on the detection and cleaning effect.

[0033] In this embodiment, as Figures 1-3 As shown, the monitoring cylinder 2 is fixed to the top surface of the base plate 1 by a number of support legs 21, and the support legs 21 are distributed in a ring with equal spacing.

[0034] A feed hopper 22 connected to its inner cavity is fixed on the top surface of the monitoring cylinder 2, and a discharge pipe 23 connected to its inner cavity is fixed at the bottom end of the monitoring cylinder 2. Solenoid valves 24 are installed on the outer walls of both the discharge pipe 23 and the feed hopper 22.

[0035] The bottom of the monitoring cylinder 2 is recessed from all sides to the center, and the parts of the monitoring cylinder 2 that come into contact with the tube body of the feed funnel 22 and the discharge pipe 23 are all equipped with sealing rings.

[0036] The monitoring cylinder 2 has a mounting hole near the left end of its circumferential inner wall. The laser emitting module 3 is embedded in the mounting hole on the inner wall of the monitoring cylinder 2. The monitoring cylinder 2 has several mounting slots near the right end of its circumferential inner wall. The mounting slots are arranged in groups of seven and vertically on the inner wall of the monitoring cylinder 2. The scattered light receiving module 4 is embedded in the mounting slot on the same side of the inner wall of the monitoring cylinder 2.

[0037] The monitoring tube 2 is fixed to the base plate 1 by a number of support legs 21 that are distributed in a ring at equal intervals, so that the monitoring tube is installed stably. The ring-shaped support legs can evenly bear the weight of the monitoring tube, ensuring the overall structure of the monitoring instrument is stable and facilitating the normal operation of the internal components.

[0038] The monitoring tube 2 is fixed to the base plate 1 by a number of support legs 21 that are distributed in a ring at equal intervals, so that the monitoring tube is installed stably. The ring-shaped support legs can evenly bear the weight of the monitoring tube, ensuring the overall structure of the monitoring instrument is stable and facilitating the normal operation of the internal components.

[0039] By setting the bottom of the monitoring cylinder 2 as a concave structure and setting a sealing ring at the connection, the soy milk in the monitoring cylinder can be drained smoothly. The concave structure facilitates liquid collection, and the sealing ring prevents material leakage, ensuring a sealed testing environment and avoiding adverse effects on the test results and the surrounding environment.

[0040] By setting mounting holes and mounting slots at specific positions on the inner wall of the monitoring cylinder 2, the laser emitting module 3 and the scattered light receiving module 4 can be installed precisely. The accurate installation of the two ensures the stability of the laser emission and scattered light receiving paths, thereby improving the accuracy and reliability of foreign object detection in soy milk.

[0041] In addition, such as Figures 1-4As shown, it also includes: a cleaning mechanism 5, which is set inside the monitoring cylinder 2 and is used to clean the inner wall of the monitoring cylinder 2. The cleaning mechanism 5 includes a brush ring 51, several bristles 52 fixed on the outer circumference of the brush ring 51, a pump body 57 installed on the top surface of the base plate 1 and used to supply cleaning fluid to the brush ring 51, and an electric cylinder 56 installed on the top surface of the base plate 1 and used to drive the brush ring 51 to move up and down. Several atomizing nozzles 53 connected to the inner cavity and used to spray cleaning fluid are installed on the upper and lower surfaces of the brush ring 51.

[0042] The brush ring 51 is located inside the monitoring cylinder 2. The side surface of the brush bristles 52 away from the brush ring 51 is tightly fitted with the inner circumferential wall of the monitoring cylinder 2. The top surface of the monitoring cylinder 2 is provided with through holes and through grooves. The cleaning mechanism 5 also includes an inlet pipe 58 fixed on the top surface of the brush ring 51 and connected to its inner cavity, and a through pipe 59 tightly sleeved with the outlet end of the pump body 57 and fixed on the outer wall of the monitoring cylinder 2 by several fixing rods 510. A corrugated pipe 511 that penetrates the through hole on the top surface of the monitoring cylinder 2 is connected between the through pipe 59 and the inlet pipe 58.

[0043] The parts of the liquid inlet pipe 59 that contact the pump body 57 and the bellows 511 are all equipped with sealing rings. The parts of the liquid inlet pipe 58 that contact the bellows 511 and the brush ring 51 are all equipped with sealing rings. The parts of the brush ring 51 that contact the atomizing nozzles 53 are also equipped with sealing rings.

[0044] The cylinder body of the electric cylinder 56 is installed on the top surface of the base plate 1. The cleaning mechanism 5 also includes a lifting rod 54 fixed on the top surface of the brush ring 51 and slidably inserted into the through groove on the top surface of the monitoring cylinder 2. The top end of the lifting rod 54 extends above the monitoring cylinder 2. A connecting rod 55 is fixed on the top surface of the lifting rod 54, and the piston rod of the electric cylinder 56 is fixed on the bottom surface of the connecting rod 55.

[0045] By rationally configuring the five cleaning mechanism components, including the brush ring 51 and the liquid inlet pipe 58, the cleaning process is made efficient. The brush ring is located inside the cylinder, with the bristles adhering to the cylinder wall. The liquid inlet pipe ensures that the cleaning liquid can be smoothly delivered to the brush ring, guaranteeing the cleaning of the soy milk on the inner wall.

[0046] By installing sealing rings at each connection point of the cleaning mechanism 5, leakage is prevented during the delivery of the cleaning fluid. The sealing rings ensure tight connections between the pump body 57, the fluid inlet pipe 59, etc., preventing leakage of the cleaning fluid, maintaining stable cleaning operation, and ensuring cleaning effectiveness.

[0047] By incorporating components such as an electric cylinder 56 and a lifting rod 54, the brush ring 51 can be stably raised and lowered for cleaning. The electric cylinder drives the connecting rod 55, causing the brush ring to move up and down along the through groove, thoroughly cleaning the inner wall of the monitoring cylinder and improving the cleaning quality.

[0048] It should be added that the two solenoid valves 24, the laser emitting module 3, the several scattered light receiving modules 4, the electric cylinder 56, and the pump body 57 are all electrically connected to the data processing and analysis module 11 through wires. The two solenoid valves 24, the laser emitting module 3, the several scattered light receiving modules 4, the electric cylinder 56, and the pump body 57 are all electrically connected to an external power supply through wires, and the data processing and analysis module 11 is also electrically connected to an external power supply through wires.

[0049] Finally, it should be noted that the data processing and analysis module 11, the two solenoid valves 24, the laser emission module 3, the several scattered light receiving modules 4, the electric cylinder 56, the pump body 57, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are all technologies known in the art.

[0050] In this embodiment, during actual use, the inlet end of the pump body 57 is first tightly connected to the supply pipe of the external cleaning liquid device. The soy milk enters the monitoring cylinder 2 through the feeding funnel 22. The solenoid valve 24 on the outer wall of the feeding funnel 22 can control the feeding.

[0051] Inside the monitoring cylinder 2, the laser emitting module 3 is installed at a specific position on the inner wall of the cylinder. It emits laser light. When there is a foreign object in the soy milk, the laser light will irradiate the foreign object and cause scattering. The scattered light receiving module 4 is also installed at the corresponding position on the inner wall of the monitoring cylinder 2. It can receive the scattered light. These scattered light receiving modules 4 are arranged vertically in groups of seven, which can capture scattered light from different angles.

[0052] After receiving the scattered light signal, the scattered light receiving module 4 transmits it to the data processing and analysis module 11 installed on the top surface of the base plate 1. The data processing and analysis module 11 analyzes and processes these signals, and then transmits the analysis results to the external display screen for display. The operator can then intuitively see whether there are foreign objects in the soy milk and related information about the foreign objects.

[0053] After the test is completed, the soy milk is discharged through the discharge pipe 23. The solenoid valve 24 on the outer wall of the discharge pipe 23 controls the discharge. At the same time, in order to prevent soy milk residue from affecting subsequent tests, the cleaning mechanism 5 starts to work. The pump body 57 is installed on the top surface of the base plate 1. It delivers the cleaning liquid from the external cleaning liquid supply device to the inside of the brush ring 51 through the liquid pipe 59, the corrugated pipe 511 and the liquid inlet pipe 58. The atomizing nozzles 53 on the upper and lower sides of the brush ring 51 atomize and spray the cleaning liquid. At the same time, the electric cylinder 56 drives the connecting rod 55, which drives the lifting rod 54 connected to the brush ring 51, so that the brush ring 51 moves up and down. The brush bristles 52 are in close contact with the inner wall of the monitoring cylinder 2 to clean the soy milk material remaining on the inner wall and keep the inside of the monitoring cylinder 2 clean.
