Description

Technical Field

[0001] The invention belongs to the technical field of biological detection, and in particular relates to a pretreatment device and a pretreatment method for monitoring raw milk. Background Art

[0002] "Fresh milk" is also commonly called raw milk, which is the common name for raw milk that has not been sterilized, homogenized, or processed. A small amount of "fresh milk" is sold in bulk on the market, and consumers usually boil it for drinking after purchasing it. The pre-packaged pure milk sold in boxes and bags is made by cooling, inspecting raw milk, removing impurities, standardizing, homogenizing, and sterilizing (pasteurization or ultra-high temperature sterilization) "fresh milk", and is a product that meets the relevant national standards.

[0003] During the production of fresh dairy products, in order to ensure the quality of fresh dairy products, it is usually necessary to test the raw milk. Fresh milk needs to be transported and stored at low temperature, so before testing, it is usually necessary to pre-treat the raw milk by water bath heating. After searching, China Utility Model Patent Publication No. CN221826602U discloses a pre-treatment device for raw milk testing. In this technical solution, the raw milk is evenly heated by a heating device. However, in this technical solution, since the raw milk is in a static state in the container, it is easy to produce sedimentation. After sedimentation, the components in the raw milk are deposited at the bottom of the container, which affects the effect of water bath heating on the one hand, and on the other hand, during subsequent testing, the staff needs to shake the container to make the deposited components float up, which reduces the overall operating efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a pretreatment device and a pretreatment method for monitoring raw milk.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A pretreatment device for monitoring fresh milk, comprising a water bath heating component, and further comprising:

[0007] A rotating disk rotatably connected to the water bath heating assembly, wherein a plurality of mounting openings are provided on an end surface of the rotating disk;

[0008] A hoop connected to the rotating disk by pivoting, the hoop is located in the mounting opening and freely swings around the axial direction of the pivot in the mounting opening;

[0009] A container is placed in the hoop, wherein the upper edge of the container is provided with an outwardly turned flange, and the lower end surface of the flange abuts against the upper end surface of the hoop;

[0010] An oscillating component is disposed in the water bath heating component, and the oscillating component is used to drive at least one of the hoops to swing when the rotating disk rotates.

[0011] Through the above technical solution, the rotating disk drives the container to rotate, so that the position of the container in the water bath heating component is changed alternately, thereby avoiding uneven heating. In addition, when the container rotates with the rotating disk, the oscillation component produces an oscillation effect on the container, thereby reducing the sedimentation of fresh milk in the container, facilitating subsequent detection operations, and also preventing the sediment from affecting the water bath heating effect of the fresh milk in the container.

[0012] Furthermore, the water bath heating assembly includes a water bath with a partially open top surface, a controller is installed on the top of the water bath, a heating element is also installed on the water bath, the heating element is electrically connected to the controller, a support column is vertically installed on the bottom wall of the water bath, and the rotating disk is coaxially rotatably connected to the upper end of the support column.

[0013] Through the above technical solution, the controller controls the operation of the heating element and sets the voltage, current and other parameters of the heating element, so that the heat generated by the heating element can be controlled, which is convenient for timely adjusting the water bath temperature during water bath heating.

[0014] Furthermore, a transmission rack is coaxially fixedly connected to the end surface of the rotating disk, a motor is installed on the side wall of the water bath, and a gear is sleeved on the output shaft of the motor, and the gear is meshed with the transmission rack.

[0015] Through the above technical solution, the output shaft of the motor rotates, driving the gear to rotate. When the gear rotates, the gear meshes with the transmission rack, thereby driving the rotating disk to rotate, which is more convenient to operate.

[0016] Furthermore, the oscillation component includes a lifting unit and a swinging unit. The lifting unit is used to drive the multiple containers to be lifted and lowered alternately when the rotating disk rotates, and the swinging unit is used to drive the pivot to rotate when the containers are lifted and lowered.

[0017] Through the above technical solution, the lifting unit drives the container to lift and lower. On the one hand, the sediment in the container and the fresh milk flow, thereby reducing the generation of sediment. On the other hand, after the water bath heating is completed, the container is driven to move upward so that the flange of the container rises above the hoop, making it convenient for staff to take the container for inspection. The swing unit drives the container to swing, thereby further causing the sediment in the container to swing back and forth, thereby reducing the generation of sediment.

[0018] Furthermore, the lifting unit includes a plurality of brackets fixedly connected to the lower end surface of the rotating disk, the horizontal section of the lower end of the bracket is located below the container, and a lifting rod is vertically penetrated through the lower end of the bracket, the lifting rod slides vertically and freely on the bracket, the upper end of the lifting rod is hinged with a support plate, the top surface of the support plate is against the bottom of the container, a fixing ring is fixedly connected to the inner bottom wall of the water bath, an arc-shaped protrusion is integrally fixedly connected to the upper end surface of the fixing ring, and the bottom of the lifting rod is in sliding contact with the upper end surface of the fixing ring.

[0019] Through the above technical solution, when the rotating disk rotates, the bottom of the lifting rod slides alternately on the upper end surface of the fixed ring and the upper surface of the arc-shaped protrusion, thereby driving the support plate to move up and down, thereby lifting the container and allowing the container to reciprocate up and down.

[0020] Furthermore, a ball is rotatably embedded at the bottom of the lifting rod, and the ball is in rolling contact with the upper end surface of the fixing ring.

[0021] Through the above technical solution, the ball rolls on the upper end surface of the fixing ring, replacing the sliding between the bottom of the lifting rod and the upper end surface of the fixing ring, thereby reducing the mechanical wear of the bottom of the lifting rod.

[0022] Furthermore, a rubber layer is provided on the surface of the support plate.

[0023] Through the above technical solution, when placing the container, the bottom of the container has soft contact with the surface of the support plate, thereby preventing the container from being damaged by bumps.

[0024] Furthermore, a lifting ring is fixedly sleeved on the periphery of the lifting rod, and a reset spring is sleeved around the periphery of the lifting rod. Two ends of the reset spring in the elastic force direction elastically press against the lifting ring and the horizontal section of the bracket respectively.

[0025] Through the above technical solution, when the support plate lifts the container, the lifting ring will compress the reset spring, so that the reset spring is in a state of accumulating elastic potential energy. When the support plate moves downward, the elastic potential energy of the reset spring is released, thereby driving the lifting ring and the lifting rod to move downward quickly and reset, so that the ball at the bottom of the lifting rod maintains contact with the end face of the fixed ring.

[0026] Furthermore, the swing unit includes a wing plate fixed to the periphery of the lifting ring, a driving rod is vertically fixed to the surface of the wing plate, a notch groove is provided at the upper end of the driving rod for the pivot to pass freely, a first rack segment and a second rack segment are respectively provided on the inner walls on both sides of the notch groove, the first rack segment and the second rack segment are alternately arranged up and down, a gear segment is provided at the periphery of the pivot, and when the driving rod moves vertically, the gear segment will alternately mesh with the first rack segment and the second rack segment.

[0027] Through the above technical solution, when the driving rod moves up and down, the gear segment will alternately mesh with the first rack segment and the second rack segment, and because the first rack segment and the second rack segment are respectively located on the inner walls on the opposite sides of the notch groove, the rotation directions of the gear segments are opposite when the two are meshed with the gear segment, thereby achieving the drive rod to drive the pivot to swing back and forth when it moves vertically, thereby driving the hoop and the container to swing back and forth.

[0028] A pretreatment device for monitoring fresh milk, applied to the pretreatment device as described above, comprising:

[0029] Placing multiple containers containing raw milk to be tested in the hoop accordingly, starting the water bath heating component, and using the water bath heating component to heat the multiple containers in a water bath;

[0030] The rotating disk rotates, causing the positions of multiple containers in the water bath heating component to change alternately. During the rotation of the rotating disk, the oscillation component is used to drive the multiple containers to move vertically alternately, and during the vertical movement, the pivot will swing back and forth, thereby driving the hoop and the container to swing, thereby oscillating the fresh milk in the container.

[0031] Through the above technical solution, when the rotating disk rotates, on the one hand, the fresh milk in the container can be evenly heated in a water bath, and on the other hand, the fresh milk in the container can be shaken to reduce the generation of sediment.

[0032] The beneficial effects of the present invention are as follows:

[0033] (1) In the present invention, the rotating disk drives the container to rotate, so that the position of the container in the water bath heating component is in an alternating state, thereby avoiding uneven heating. In addition, when the container rotates with the rotating disk, the oscillating component produces an oscillating effect on the container, thereby reducing the sedimentation of the fresh milk in the container, facilitating subsequent detection operations, and also preventing the sediment from affecting the water bath heating effect of the fresh milk in the container;

[0034] (2) The lifting unit in the present invention drives the container to move up and down. On the one hand, the sediment in the container and the fresh milk flow, thereby reducing the generation of sediment. On the other hand, after the water bath heating is completed, the container is driven to move upward so that the flange of the container rises above the hoop, which is convenient for the staff to take the container for inspection. The swing unit drives the container to swing, further causing the sediment in the container to swing back and forth, thereby reducing the generation of sediment.

[0035] (3) In the present invention, when the driving rod moves up and down, the gear segment will alternately mesh with the first rack segment and the second rack segment. Since the first rack segment and the second rack segment are respectively located on the inner walls on the opposite sides of the notch groove, the rotation directions of the gear segments are opposite when the two are meshed with the gear segment. Therefore, when the driving rod moves vertically, it can drive the pivot to swing back and forth, thereby driving the hoop and the container to swing back and forth. The structure is simple, and no additional electrical control components are required for operation, so the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figure 1-Figure 8 As shown, this embodiment provides a pretreatment device for monitoring fresh milk, including a water bath 2, in which a proper amount of clean water is put, the top surface of the water bath 2 is partially open, and a controller 1 is installed on the top thereof, and a heating element 10 is also installed on the top of the water bath 2. The heating element 10 in this embodiment can be an electric heating rod, and the heating element 10 is electrically connected to the controller 1. The controller 1 controls the operation of the heating element 10 and sets the parameters such as the voltage and current of the heating element 10, so that the heat generated by the heating element 10 can be controlled, so as to facilitate timely adjustment of the water bath temperature during water bath heating;

[0047] Combination Figure 2 As shown, a support column 7 is vertically installed on the inner bottom wall of the water bath 2, and a bearing is installed on the upper end of the support column 7. A rotating disk 9 is fixedly sleeved on the outer ring of the bearing, and the rotating disk 9 is coaxial with the support column 7. Three installation openings are opened on the end face of the rotating disk 9, and a pivot 13 is penetrated on the inner ring wall of the installation opening. The pivot 13 can rotate freely on the inner ring wall of the installation opening. In addition, an annular hoop 8 is fixedly connected to the pivot 13, and the hoop 8 is located in the installation opening and freely swings around the axial direction of the pivot 13 in the installation opening. A container 3 is placed on each of the three hoop 8, and an outer-turned flange is provided on the upper edge of the container 3. The lower end face of the flange abuts against the upper end face of the hoop 8, so that the container 3 will not slide off the hoop 8;

[0048] Combination Figure 1 and Figure 2 As shown, the upper end surface of the rotating disk 9 is coaxially fixed with a transmission rack 4, and a motor 6 is installed on the side wall of the water bath 2. The output shaft of the motor 6 is sleeved with a gear 5, and the gear 5 is meshed with the transmission rack 4. After the motor 6 is energized, its output shaft rotates and drives the gear 5 to rotate. When the gear 5 rotates, the gear 5 meshes with the transmission rack 4 for transmission, thereby driving the rotating disk 9 to rotate, and then causing the container 3 to rotate around the axial direction of the support column 7 in the water bath 2;

[0049] Combination Figure 3 and Figure 5As shown, three brackets 14 with a roughly L-shaped outer contour are fixedly connected to the lower end surface of the rotating disk 9, the horizontal section of the lower end of the bracket 14 is located below the container 3, and a lifting rod 18 is vertically penetrated at the lower end of the bracket 14, and the lifting rod 18 slides vertically and freely on the bracket 14, and a support plate 22 is hinged on the upper end of the lifting rod 18, and the top surface of the support plate 22 is against the bottom of the container 3. A fixing ring 11 is fixedly connected to the inner bottom wall of the water bath 2, and an arc-shaped protrusion 12 is fixedly formed on the upper end surface of the fixing ring 11. A ball 19 is rotatably embedded at the bottom of the lifting rod 18, and the ball 19 rolls and contacts the upper end surface of the fixing ring 11. When the rotating disk 9 rotates, the lifting rod 18 The ball 19 installed at the bottom will roll alternately on the upper end surface of the fixing ring 11 and the upper surface of the arc-shaped protrusion 12, thereby driving the support plate 22 to move up and down, thereby lifting the container 3 and allowing the container 3 to reciprocate up and down. In addition, a rubber layer (not shown in the figure) is provided on the surface of the support plate 22, and a lifting ring 16 is fixedly sleeved on the periphery of the lifting rod 18. A reset spring 15 is sleeved around the periphery of the lifting rod 18. The two ends of the reset spring 15 in the elastic force direction elastically press against the lifting ring 16 and the horizontal section of the bracket 14 respectively. Of course, the reset spring 15 can also be replaced by a component with elastic deformation ability such as an elastic cushion in the prior art.

[0050] Combination Figures 4 to 8 As shown, a wing plate in a horizontal state is fixedly connected to the periphery of the lifting ring 16, and a driving rod 17 is vertically fixedly connected to the surface of the wing plate. A notch groove is provided at the upper end of the driving rod 17 for the pivot 13 to pass freely. The inner walls on both sides of the notch groove are respectively provided with a first rack segment 21 and a second rack segment 23. The first rack segment 21 and the second rack segment 23 are staggered up and down. A gear segment 20 is provided at the periphery of the pivot 13. When the driving rod 17 moves vertically, the gear segment 20 will alternately mesh with the first rack segment 21 and the second rack segment 23.

[0051] The working principle of this embodiment is as follows:

[0052] Place three containers 3 containing raw milk to be tested in three hoops 8 respectively, connect to an external power source, and pre-adjust the parameters of the controller 1, so that the heating element 10 is powered on to heat and generate appropriate heat. The heating element 10 heats the clean water in the water bath 2, and the containers 3 are heated by the clean water in the water bath;

[0053] During the heating process, the motor 6 is started, the output shaft of the motor 6 rotates, and drives the gear 5 to rotate. When the gear 5 rotates, the gear 5 meshes with the transmission rack 4 for transmission, and then drives the rotating disk 9 to rotate, so that the container 3 rotates around the axial direction of the support column 7 in the water bath 2, so that the position of the container 3 in the water bath 2 changes alternately, and uniform water bath heating is achieved;

[0054] As the rotating disk 9 rotates, the ball 19 at the bottom of the lifting rod 18 corresponding to one of the containers 3 will roll the upper surface of the arc-shaped protrusion 12 from the upper end surface of the fixing ring 11, thereby lifting the support plate 22, and the support plate 22 will drive the container 3 to move upward. When the support plate 22 moves upward, the driving rod 17 also moves upward synchronously, thereby making the gear segment 20 of the pivot 13 alternately mesh with the first rack segment 21 and the second rack segment 23, and because the first rack segment 21 and the second rack segment 23 are respectively located on the inner walls on the opposite sides of the notch groove, when the two mesh with the gear segment 20, the rotation direction of the gear segment 20 is in the opposite state, thereby realizing that when the driving rod 17 moves vertically, it can drive the pivot 13 to swing back and forth, thereby driving the hoop 8 and the container 3 to swing back and forth, thereby vibrating the fresh milk in the container 3;

[0055] When the support plate 22 moves upward, the lifting ring 16 will compress the return spring 15, so that the return spring 15 is in a state of accumulating elastic potential energy. When the support plate 22 moves downward, the elastic potential energy of the return spring 15 is released, thereby driving the lifting ring 16 and the lifting rod 18 to move downward and reset quickly, thereby making the ball 19 at the bottom of the lifting rod 18 maintain contact with the end face of the fixing ring 11, so that when the ball 19 rolls from the upper surface of the arc-shaped protrusion 12 to the end face of the fixing ring 11, the elastic potential energy of the return spring 15 is released, thereby driving the lifting rod 18 to move downward and reset.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
