Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dairy product processing equipment, in particular to a liquid storage tank for dairy product processing with adjustable anti-solidification. BACKGROUND

[0002] In the dairy product processing industry, the storage of raw materials is crucial, as it directly affects the quality of subsequent products and the smoothness of the production process. Traditional raw material storage devices for dairy products are relatively basic and only provide simple storage of raw materials. However, the characteristics of dairy raw materials make them extremely sensitive to environmental conditions, especially temperature, which can easily cause a series of problems.

[0003] Temperature fluctuations or unsuitable temperatures can easily cause raw materials to solidify. This solidification problem is harmful in many ways, most notably affecting the quality of raw material storage, which can change the physical and chemical properties of the raw materials, leading to loss of nutritional content or deterioration in quality. Moreover, solidified raw materials are difficult to use in subsequent processes. In the transportation process, solidified materials can clog the pipeline, making it difficult for raw materials to be smoothly transported to processing equipment. In severe cases, production may need to be stopped to clean the pipeline, greatly affecting production efficiency. In the processing process, solidified raw materials entering the equipment can cause equipment to run slowly and damage critical components, increasing equipment maintenance costs and potentially resulting in uneven product quality and a significant increase in defective products.

[0004] A patent with the Chinese invention patent publication number CN112791619A discloses a liquid storage tank for dairy product processing with adjustable anti-solidification, which includes a storage tank, an adjusting rod is connected to the outside of the storage tank, an adjusting ball is fixedly connected to the side of the adjusting rod close to the storage tank, a pawl is movably connected to the outside of the crank wheel, a pull rod is movably connected to the front of the crank wheel, a support rod is movably connected to the outside of the stirring shaft, a limit plate is movably connected to the side of the support rod away from the stirring shaft, and a support spring is fixedly connected to the side of the limit plate close to the support rod. The liquid storage tank for dairy product processing with adjustable anti-solidification can be used for different raw materials by rotating the adjusting rod, which makes the adjusting ball expand, the adjusting ball reduces the size of the top ball through the air pipe, the top ball drives the slide rod to slide, the slide rod reduces the number of slide rings on the outside, and the slide rings are used in cooperation with the elastic ropes, thereby achieving the effect of being suitable for different raw materials.

[0005] However, the above-mentioned technology often has the following defects: the technology relies on indirect regulation means such as adjusting ball inflation, and fails to build a direct correlation mechanism with temperature change. When encountering sudden temperature rise or drop, or when processing raw materials with abnormal milk fat content or special colloidal stability, the regulation and response speed cannot meet the actual demand, and it is difficult to ensure that the raw materials always maintain a uniform and stable liquid storage state. Local solidification may form clumps, thereby affecting the continuity of the subsequent processing link and the uniformity of product quality.

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figure 1 As shown, this embodiment of the invention includes a liquid storage shell 1, an inner liner 2 fitted onto the inner arc surface of the liquid storage shell 1, a bent connecting plate 101 near the inner liner 2, an infrared radiation heating layer 102 between the bent connecting plate 101 and the inner arc surface of the liquid storage shell 1, and an insulating and heat-preserving layer 103 between the bent connecting plate 101 and the inner liner 2. A junction box 3 is fixedly installed on one side of the outer arc surface of the liquid storage shell 1 by bolts. Terminal posts 301 are connected to both the upper and lower surfaces of the junction box 3. An auxiliary heating element 4 is connected through the inner arc surface of the terminal post 301. The outer arc surface of the auxiliary heating element 4 penetrates the interior of the infrared radiation heating layer 102 and extends one end into the inner liner 2.

[0041] The inner bending connecting plate 101 of the liquid storage shell 1 serves to connect and fix the infrared radiation heating layer 102 and the insulation layer 103 in an orderly manner between the liquid storage shell 1 and the inner liner 2, forming a layered functional structure. The inner liner 2 is the container that directly stores dairy raw materials, and the various layers surrounding it all achieve the functions of insulation and heating. When the equipment is powered on, the external power supply is connected through the junction box 3. The junction box 3 acts as the circuit connection hub, transmitting the current through the upper and lower terminals 301 to the infrared radiation heating layer 102 and the auxiliary heating element 4, respectively.

[0042] When the infrared radiation heating layer 102 is powered on, heat is transferred to the inner container 2 by generating infrared radiation, and the raw materials in the inner container 2 are heated from the inside by using the characteristics of infrared radiation. The auxiliary heating element 4 extends through the infrared radiation heating layer 102 and into the inner container 2, directly contacting the raw materials. When the heating effect of the infrared radiation heating layer 102 is insufficient or needs to quickly raise the local temperature, the auxiliary heating element 4 is activated to supplement the heat through direct heat conduction, ensuring that the temperature of the raw materials in the inner container 2 is maintained within the appropriate range. The insulating layer 103 is located between the bending connecting plate 101 and the inner container 2, which not only blocks the transfer of heat to the liquid storage shell 1, reducing heat loss, but also prevents external environmental temperature from interfering with the internal heating environment, maintaining the stability of the temperature in the inner container 2. Thus, the infrared radiation heating layer 102 and the auxiliary heating element 4 work together to achieve the anti-freezing storage of dairy raw materials.

[0043] As shown in Figure 2 , Figure 5 and Figure 9 , the inner arc surface of the liquid storage shell 1 is connected through the electromagnetic heating assembly 5. The electromagnetic heating assembly 5 includes a coil disc seat 51 that is sleeved on the outer arc surface of the inner container 2. A container collar 52 is fixedly installed on the upper surface edge of the coil disc seat 51. The inner arc surface of the container collar 52 is sleeved on the outer arc surface of the inner container 2. The upper surface of the coil disc seat 51 is provided with a protruding rib 53. The protruding rib 53 is provided with a plurality of winding grooves arranged along the circumference thereof. The outer arc surface of the protruding rib 53 is provided with a concave area 531. The lower surface of the coil disc seat 51 abuts against a magnetic conducting plate 54. A heat-conducting sheet 6 is sleeved between the coil disc seat 51 and the magnetic conducting plate 54. The upper surface of the heat-conducting sheet 6 is provided with a plurality of holes. One end of the auxiliary heating element 4 extends into the inner arc surface of the protruding rib 53 on the coil disc seat 51.

[0044] The protruding rib 53 on the surface of the coil disc seat 51 is provided with winding grooves arranged along the circumference. High-frequency electromagnetic coils are wound in the grooves. When the coils are connected to an alternating current through the junction box 3, a high-frequency alternating magnetic field is generated. The inner container 2 is made of a magnetic conducting metal material. Its outer arc surface is tightly sleeved on the coil disc seat 51 through the container collar 52 and is completely within the coverage range of the alternating magnetic field. According to the principle of electromagnetic induction, eddy currents are excited inside the inner container 2. When the eddy currents flow in the metal, they are converted into heat energy due to the resistance effect, causing the inner container 2 to rapidly heat up, and then directly heating the internal dairy raw materials through heat conduction.

[0045] The convex rib 53 not only provides a stable winding space for the coil, but also increases the heat dissipation area by the low concave area 531 of the outer arc surface, thereby avoiding performance degradation caused by overheating of the coil during long-term operation. The magnetic conducting plate 54 abutting the lower surface of the coil disc seat 51 is made of a high magnetic permeability material, which can concentrate and guide the magnetic field generated by the coil to the inner container 2, reduce the energy loss of the magnetic field spreading outward, and greatly improve the heating efficiency. The heat-conducting sheet 6 is sleeved between the coil disc seat 51 and the magnetic conducting plate 54, and the holes formed on the surface of the heat-conducting sheet 6 not only reduce the structure weight, but also assist in heat dissipation through air circulation. When the coil generates heat during operation, the heat-conducting sheet 6 quickly conducts the residual heat of the coil disc seat 51 to the magnetic conducting plate 54 through the closely fitted contact surface 841, thereby avoiding local overheating of the coil and allowing the magnetic conducting plate 54 to absorb heat and supplement heating of the bottom of the inner container 2 through heat radiation, forming a double heating mode of electromagnetic heating and residual heat reuse.

[0046] In addition, the auxiliary heating element 4 extends into the inner arc surface of the convex rib 53, which can directly supplement the heat to the coil disc seat 51 when the electromagnetic heating power is insufficient, and through the secondary conduction of the heat-conducting ring sheet 6 and the magnetic conducting plate 54, the temperature of the inner container 2 is uniformly and stably ensured, and the freezing of the dairy raw material due to local low temperature is effectively prevented.

[0047] As shown in Figure 3 , Figure 4 and Figure 6 , the upper end surface of the magnetic conducting plate 54 is sleeved with an insulating support ring 7, the upper surface of the insulating support ring 7 is provided with a receiving section 701, the receiving section 701 is placed at the bottom of the coil disc seat 51 and the top of the magnetic conducting plate 54, the lower surface of the insulating support ring 7 is provided with an inner recess 702, the top surface of the insulating support ring 7 away from the inner recess 702 is provided with an outer stop portion 703, the outer arc surface of the outer stop portion 703 is sleeved with a movement assembly 8, the movement assembly 8 includes a ring-shaped connecting portion 81 sleeved on the outer arc surface of the outer stop portion 703, the outer arc surface of the ring-shaped connecting portion 81 is provided with an outer convex end 811, the upper surface of the outer convex end 811 is connected with a driving shaft sleeve 82, the outer arc surface of the driving shaft sleeve 82 is provided with an outer expansion portion 821, the lower surface of the outer expansion portion 821 abuts with a spring 83, one end of the spring 83 is fixedly installed on the surface of the insulating support ring 7, the top end of the driving shaft sleeve 82 is placed in the middle of the inner bottom wall of the inner container 2, the outer arc surface of the driving shaft sleeve 82 is fixedly installed with a stirring knife 84, the outer arc surface of the stirring knife 84 is provided with a contact surface 841 on both sides, and the stirring knife 84 is matched with the inner container 2 through the contact surface 841.

[0048] The receiving section 701 of the upper end surface of the insulating support ring 7 is tightly clamped between the bottom of the coil disc seat 51 and the top of the magnetic conductive plate 54, and the current conduction between the electromagnetic heating assembly 5 and the lower transmission structure is blocked by the insulating material to avoid the risk of electric leakage. The inner recess 702 in the middle part provides a through installation space for the shaft rod, one end of the shaft rod is connected to the driving shaft sleeve 82, and the other end receives power through the gear 10 to form a transmission channel. The outer stopper 703 at the top limits the radial displacement of the shifting assembly 8 through the annular protruding structure to ensure the stability of the transmission.

[0049] The shifting assembly 8 is sleeved on the outer arc surface of the outer stopper 703 through the annular connecting part 81, and the outer convex end 811 of the shifting assembly 8 is attached to the bottom of the driving shaft sleeve 82 to form axial support. When the shaft rod receives rotary power through the gear 10, the driving shaft sleeve 82 rotates synchronously with the shaft rod to drive the high-speed rotation of the stirring blade 84 on the outer arc surface. The contact surfaces 841 on both sides of the stirring blade 84 maintain a small gap with the inner wall of the inner container 2, and can form shearing and stirring effects on the raw materials during rotation to break the local solidification trend and avoid direct friction with the container wall to cause wear.

[0050] The spring 83 abuts between the outer expansion part 821 at the bottom of the driving shaft sleeve 82 and the insulating support ring 7 to form an elastic buffer structure. When the raw material flow resistance changes or the stirring blade 84 contacts a small amount of solidified block, the spring 83 can make the driving shaft sleeve 82 move up and down along the axial direction through elastic deformation to drive the stirring blade 84 to form a combined motion track of rotation and axial oscillation, expand the stirring range, and enhance the disturbance effect on the raw materials to destroy the sediment or solidified layer easily formed at the bottom of the inner container 2.

[0051] As shown in Figure 7 and Figure 8 , the inner arc surface of the driving shaft sleeve 82 is drivingly connected with the liquid storage circulating assembly 9. The liquid storage circulating assembly 9 includes an impeller 91 sleeved in the inner arc surface of the driving shaft sleeve 82. The lower surface of the impeller 91 is provided with a threaded sleeve column 911. The outer arc surface of the threaded sleeve column 911 is threadedly connected with a moving shaft sleeve 92. The outer arc surface of the moving shaft sleeve 92 is placed in the inner arc surface of the annular connecting part 81. The inner arc surface bottom of the moving shaft sleeve 92 is connected with a dispersing cone head 93. The lower surface of the dispersing cone head 93 is provided with a circulating material hole 931. The lower surface of the dispersing cone head 93 is placed on the top of the insulating support ring 7. The inner recess 702 of the lower surface of the insulating support ring 7 is connected with the shaft rod. One end of the shaft rod is connected with the driving shaft sleeve 82. The shaft rod fixedly installed with the gear 10 in the middle part of the inner recess 702 is in the same vertical plane with the stirring blade 84.

[0052] The impeller 91 of the liquid storage circulating assembly 9 is sleeved on the inner arc surface of the driving shaft sleeve 82, and is in synchronous rotation with the driving shaft sleeve 82. When the driving shaft sleeve 82 rotates under the driving of the gear 10, the impeller 91 rotates at a high speed. The blades generate a thrust force on the surrounding raw milk, forming an upward liquid flow force. The threaded sleeve column 911 on the lower surface of the impeller 91 is connected with the moving shaft sleeve 92 through threads. The relative position of the two can be adjusted according to the viscosity characteristics of the raw material. When the moving shaft sleeve 92 is tightened, the distance between the impeller 91 and the dispersion cone head 93 is reduced, the liquid flow is narrowed, and the high-viscosity raw material is suitable for strong pushing. When it is loosened, the flow space is expanded, and the low-viscosity raw material is suitable for stable circulation.

[0053] The outer arc surface of the moving shaft sleeve 92 is attached to the inner arc surface of the annular connecting part 81. It is limited in the radial direction by the annular connecting part 81, and moves up and down synchronously with the axial movement of the driving shaft sleeve 82. The dispersion cone head 93 connected to the bottom is in a conical structure. When the raw material pushed by the impeller 91 flows through the dispersion cone head 93, the conical surface disperses the liquid flow into multiple branches, which are diffused to the surrounding through the circulation holes 931 on the lower surface.

[0054] The circulation holes 931 are evenly distributed along the circumference of the dispersion cone head 93. The dispersed raw material flows into the bottom area of the inner container 2 through the hole, and then forms a closed loop circulation path from the bottom to the middle to the top under the continuous thrust of the impeller 91. This circulation not only makes the raw material heat more evenly, avoids local temperature too low leading to solidification, but also flushes the raw material remaining on the inner wall of the inner container 2, cooperates with the shearing action of the stirring knife 84, and further prevents sedimentation and caking.

[0055] Specific working principle:

[0056] In the actual working process, when the liquid storage tank is started, the external power is connected through the junction box 3, and the current flows to the auxiliary heating element 4 and the electromagnetic heating assembly 5 through the terminal post 301, respectively, to start the multi-level heating mode. In the electromagnetic heating assembly 5, the coil in the winding groove on the coil disc seat 51 generates a high-frequency alternating magnetic field under the action of the current. The magnetic plate 54 greatly enhances the magnetic field strength and concentrates it towards the inner container 2, so that the inner container 2 generates eddy current due to electromagnetic induction. When the eddy current flows in the metal inner container 2, it is converted into heat energy, which makes the inner container 2 heat up quickly, and directly heats the internal raw milk. At the same time, the auxiliary heating element 4 is started synchronously, one end of which extends into the inner container 2 and directly contacts with the raw material, and supplements the heat through heat conduction. The infrared radiation heating layer 102 releases infrared radiation, which penetrates the surface of the raw material and goes deep into the interior, so that the raw material is uniformly heated from the inside to the outside, avoiding excessive local temperature difference. The insulating heat preservation layer 103 tightly wraps the outer side of the inner container 2 to block the heat transfer to the liquid storage shell 1 and the external environment, reducing heat loss and maintaining the temperature in the inner container 2 within the appropriate range.

[0057] When the heating system is operating efficiently, the gear 10 starts to rotate under the external power drive, and the power is transmitted to the drive sleeve 82 through the shaft, which drives the drive sleeve 82 to rotate at high speed, and the stirring knife 84 on the outer arc surface of the drive sleeve 82 rotates, and the contact surfaces 841 on both sides keep a precise gap with the inner wall of the inner container 2, and in the rotating process, the raw materials are subjected to strong shearing and stirring, which breaks the solidification trend of the raw materials due to temperature changes, and at the same time, the raw materials that may be left on the wall of the container are scraped off, ensuring the uniformity of the raw materials in heating and stirring. The impeller 91 in the liquid storage circulating assembly 9 rotates synchronously with the drive sleeve 82, and the blades push the raw materials to form an upward flow, and the raw materials enter the dispersion cone head 93 through the moving sleeve 92, and are dispersed into multiple branches by the conical surface, and then spread to the surrounding through the circulating material holes 931 on the lower surface, and then flow into the bottom area of the inner container 2, and then under the continuous thrust of the impeller 91, a closed loop circulation path is formed, so that the raw materials are fully mixed in the circulation, and the uniform heating is further ensured. In addition, the spring 83 below the outer expansion part 821 of the bottom of the drive sleeve 82 will produce elastic stretching due to the change of the flow resistance of the raw materials when the drive sleeve 82 rotates, so that the drive sleeve 82 realizes up and down movement while rotating, and the stirring knife 84 and the impeller 91 move up and down synchronously, which greatly expands the range of stirring and circulation, and even the raw materials in the corners of the inner container 2 can be fully stirred and circulated, and the anti-solidification effect is significantly improved.

[0058] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
