Description

Technical Field

[0001] This utility model belongs to the technical field of colostrum sterilizers, specifically relating to a water bath heating device for colostrum sterilizers. Background Technology

[0002] Colostrum is the milk secreted by mammals in the early postpartum period. Rich in immunoglobulins and other bioactive substances, it possesses extremely high nutritional value and immunomodulatory functions, and is widely used in the production of infant formula, health products, and special nutritional supplements. To ensure the safety and stability of colostrum during subsequent storage and transportation, it typically undergoes pasteurization. Currently, a common colostrum pasteurization method includes water bath heating, which involves placing the colostrum container in heated water to a specific temperature and maintaining it for a certain time to inactivate pathogenic microorganisms.

[0003] While existing water bath heating sterilization devices can achieve basic pasteurization of colostrum, they still have the following technical problems: First, the colostrum heating process often requires the use of electric heating elements, such as U-shaped heating rods, to raise the water temperature. These elements are usually located on the inner wall of the water tank, and to prevent the high-temperature heating elements from contacting the colostrum bags and causing damage, they are often shielded by protective mesh frames. However, the addition of protective structures physically hinders the free flow of water, causing localized heat accumulation or cold zones within the water tank, resulting in uneven water temperature distribution and affecting the sterilization effect. Second, in order to improve water circulation, some structures attempt to drive water flow through rotating devices, but it is difficult to create effective water flow disturbance within the protected area of ​​the heating elements, resulting in low heat exchange efficiency between the water inside and outside the protective mesh frame and poor overall heating uniformity. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a colostrum bag water bath heating device that can ensure the safety of the colostrum bag while improving the flow of water inside and outside the protected area, thereby enhancing the overall heating uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a colostrum sterilizer water bath heating device, comprising a water tank, wherein the water tank is filled with clean water, a rotating frame is installed inside the water tank, a squeezing rod is symmetrically arranged at one end of the rotating frame, and U-shaped heating elements are symmetrically installed at the bottom inside the water tank, and a protective net frame is covered on the surface of the U-shaped heating elements.

[0006] The upper surface of the protective net frame is provided with a track groove, and a slider is evenly slidably installed inside the track groove. A toggle plate is provided at the bottom of the slider. The toggle plate is placed inside the U-shaped heating element. The toggle plate pushes out the high-temperature water inside the protective net frame by reciprocating movement.

[0007] Furthermore, the inner wall of the water tank near the extrusion rod is symmetrically provided with protrusions, and a slide rod is vertically slidably installed on the surface of the protrusion.

[0008] Furthermore, a connecting crossbar is fixed between the tops of the plurality of sliders, and a connecting rod is hinged to the bottom of the slider, with one end of the connecting rod away from the slider hinged to the top of one of the sliders.

[0009] Furthermore, a limiting head is provided at the top of the slide rod, the slide rod passes through the boss, and a spring is sleeved on the surface of the slide rod, with the spring positioned between the limiting head and the boss.

[0010] Furthermore, a compression connecting plate is laterally fixed between the bottoms of the two slide rods, and the compression rod presses down on the compression connecting plate.

[0011] Furthermore, the surface of the rotating frame is symmetrically provided with colostrum placement baskets, and colostrum bags are placed inside the colostrum placement baskets.

[0012] Furthermore, a sealing door is hinged to the top of the water tank, and an electrical control box is installed on one side of the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The protective mesh frame surrounding the U-shaped heating element effectively prevents the colostrum bag from coming into contact with the high-temperature U-shaped heating element during rotation, thus avoiding burns or ruptures and ensuring the safety of the colostrum during pasteurization and the operational stability of the sterilization equipment. The protective mesh frame structure forms a closed protective area through fixed installation, which not only improves the safety performance of the equipment but also solves the problem of colostrum bags being easily damaged by high temperatures mentioned in the background technology.

[0015] By setting track grooves on the protective net frame, and installing reciprocating sliding sliders and a deflector plate at the bottom within the track grooves, combined with the rotational drive of the rotating frame to compress the sliding rod, the sliding rod drives the connecting rod to drive the slider to slide, thereby causing the deflector plate to agitate the water inside the protective net frame, achieving water flow disturbance within the protected area and effectively improving the flow exchange efficiency between the water inside and outside the net frame. This structure significantly improves the problem of local water flow stagnation caused by the protective structure, improves the uniformity of water temperature, and solves the technical problems of poor water flow and uneven heating in the prior art.

[0016] The slide bar is kept in its initial upward reset state by a spring structure, and during rotation, it works with the squeezing structure to achieve periodic lifting and lowering, thereby driving the slider to form a stable reciprocating disturbance cycle. This gives the water disturbance structure a self-resetting and automatic driving function. The addition of this structure enables the disturbance action to be completed without external electric devices, improving the overall structural simplicity and automation of the equipment, and effectively alleviating the problems of complex disturbance structures and difficult control of traditional equipment.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] refer to Figures 1-6As shown, a colostrum bag washing machine water bath heating device includes a water tank 1 filled with clean water; a rotating frame 2 is installed inside the water tank 1, which can rotate around the central axis of the water tank 1 through a bearing structure, to drive multiple colostrum placement baskets 21 to form a stable rotation in the water bath to promote heating uniformity; a squeezing rod 22 is symmetrically arranged at one end of the rotating frame 2, the squeezing rod 22 has a crank-shaped structure and can periodically contact a fixed part during rotation to trigger a longitudinal squeezing action; U-shaped heating elements 3 are symmetrically installed at the bottom of the water tank 1, the U-shaped heating elements 3 are fixed to both sides of the bottom of the water tank 1 by mounting brackets and respectively connected to the electrical control box to realize the electric heating function; a protective mesh frame 4 is covered on the surface of the U-shaped heating elements 3, the protective mesh frame 4 is fixed to the outside of the heating elements by screw connection to form a three-dimensional cage structure, to prevent the colostrum bags from directly contacting the high-temperature elements during rotation and causing damage or burns, and at the same time, the presence of the protective mesh frame 4 to a certain extent obstructs the water flow and affects the local heat exchange efficiency.

[0026] The upper surface of the protective net frame 4 is provided with a track groove 41. The track groove 41 is distributed on the top surface of the protective net frame 4 in a closed loop structure and is used to limit the running trajectory of the slider 9. The slider 9 is evenly slidably installed on the inner side of the track groove 41. The slider 9 achieves stable movement along the track groove by cooperating with the guide groove at the bottom. The bottom of the slider 9 is provided with a deflector plate 91. The deflector plate 91 is made of leaf spring steel. One end of the deflector plate is connected to the slider 9, and the other end is bent downward and extends to the inner side of the U-shaped heating element 3. The deflector plate 91 pushes out the high temperature water inside the protective net frame 4 by reciprocating movement and guides the water flow direction to improve the uniformity of water temperature conduction inside and outside the protected area and alleviate the problem of local heating deviation caused by the net frame.

[0027] refer to Figure 3 and Figure 4 As shown, the inner wall of the water tank 1 near the extrusion rod 22 is symmetrically provided with bosses 12. The bosses 12 are made of cast steel and are fixedly installed on the inner walls of both sides of the water tank 1 to provide a guide reference for the installation of the slide rod 6. The slide rod 6 is vertically slidably installed on the surface of the bosses 12. The slide rod 6 is a straight rod structure made of stainless steel. Its two ends are respectively connected to the limiting mechanism and the transmission mechanism, and it can slide up and down in the guide cavity inside the bosses 12.

[0028] refer to Figure 3 and Figure 6As shown, a connecting crossbar 92 is fixed between the tops of multiple sliders 9. The connecting crossbar 92 is fixedly connected to each slider 9 by welding process to realize the linkage and synchronous action between sliders 9. A connecting rod 8 is hinged to the bottom of the slider 6. The connecting rod 8 is connected to the slider 6 by a pin structure to form a rotatable hinge joint. The end of the connecting rod 8 away from the slider 6 is hinged to the top of one of the sliders 9. The pushing and pulling action of the connecting rod 8 drives the connecting crossbar 92, thereby driving all sliders 9 to slide back and forth in the track groove 41, realizing intermittent disturbance of the water in the protective net frame 4 during rotation.

[0029] refer to Figure 2 and Figure 6 As shown, a limiting head 61 is provided at the top of the slide rod 6. The limiting head 61 is an integral stop disc structure, and its diameter is slightly larger than the guide hole of the boss 12 to prevent the slide rod 6 from disengaging from the guide mounting cavity. The slide rod 6 passes through the boss 12, and the through part is surface polished to reduce sliding resistance. A spring 7 is sleeved on the surface of the slide rod 6. The spring 7 adopts a helical compression spring structure. The spring 7 is placed between the limiting head 61 and the boss 12. In the unforced state, the spring 7 always applies an upward restoring force to the slide rod 6 to ensure that the slider 9 is always in the initial rising position in the non-pressurized state.

[0030] refer to Figure 4 As shown, a compression connecting plate 62 is horizontally fixed between the bottoms of the two slide rods 6. The compression connecting plate 62 is a steel beam structure, riveted to the bottoms of the two slide rods 6 and passing through the longitudinal centerline of the water tank 1. The compression rod 22 presses down on the compression connecting plate 62, and transmits the torque to the slide rod 6 through the crank sliding mechanism to form an overall pressing action, which further drives the connecting rod 8 and the slider 9 to complete the turbulence and water-dispelling action.

[0031] refer to Figure 5 As shown, the surface of the rotating frame 2 is symmetrically equipped with colostrum placement baskets 21. The colostrum placement baskets 21 are made of 304 stainless steel and have a porous internal structure for rapid water permeability. The external structure is equipped with a snap-on opening and closing mechanism for easy placement and sealing of colostrum bags. Colostrum bags are placed inside the colostrum placement baskets 21. The colostrum bags are made of food-grade plastic and must be completely immersed in the hot water in the water tank 1 to receive constant temperature water bath heating to ensure stable and uniform temperature conduction, thereby achieving efficient pasteurization.

[0032] refer to Figure 1 As shown, a sealing door 11 is hinged to the top of the water tank 1. The sealing door 11 is connected to the side wall of the water tank 1 by a hinge and is equipped with a locking device to achieve airtight sealing in the closed state. An electrical control box is set on one side of the water tank 1. The electrical control box is used to supply power to the U-shaped heating element 3 and control the overall heating process. It is equipped with a temperature controller, a time relay, a power module and an overload protector to ensure the safety and stability of the system operation.

[0033] The working principle of this utility model is as follows: When in use, first inject clean water into the water tank 1, then place the colostrum bag to be sterilized into the colostrum placement basket 21, close the colostrum placement basket 21, close the sealing door 11, and energize the U-shaped heating elements 3 on both sides to heat the water inside the water tank 1. During this process, due to the presence of the springs 7 on both sides, the limiting head 61 always has an upward force, which then pushes the slide rod 6 to move upward, so that multiple sliders 9 can be pulled to one side simultaneously through the connecting rod 8. The protective net frame 4 surrounds the U-shaped heating element 3 to prevent colostrum bags from falling onto the U-shaped heating element 3 and causing scalding during the rotation of the rotating frame 2. However, due to the presence of the protective net frame 4, the water around the U-shaped heating element 3 has poor flow, which will affect the uniformity of water heating.

[0034] During the rotation of the rotating frame 2, the pressing rod 22 can press down the pressing connecting plate 62, and then the pressing connecting plate 62 drives the sliding rods 6 on both sides to move down. After the pressing rod 22 rotates, the sliding rod 6 can automatically return to its original position by the elastic force of the spring 7. Therefore, during the rotation of the rotating frame 2, the sliding rod 6 can be driven to rotate up and down. Then, the connecting rod 8 pushes multiple sliders 9 to slide back and forth along the track groove 41, so as to push the water flow inside the protective net frame 4 through the actuating plate 91, thereby increasing the fluidity of the water inside and outside the protective net frame 4, reducing the temperature difference, and ensuring the uniformity of the water temperature.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
