Abstract
Description
Technical Field
[0001] This application relates to the technical field of goat milk storage, and more specifically, to a bottom-in, bottom-out goat milk storage tank loading and unloading structure. Background Technology
[0002] Goat milk has higher nutritional value than cow milk and is known as the "king of milk". It is not only an important food source for lambs after birth, but also occupies an important place in human life. As a nutritious but perishable dairy product, goat milk requires extremely strict equipment for storage.
[0003] Fresh goat milk is usually stored in storage tanks after collection. Traditional goat milk storage tanks are mostly top-in, top-out structures, and sealed with lids. However, the inventors realized that traditional storage tanks only have an opening at the top for feeding and discharging. When goat milk flows in from a height, the surface area in contact with air is large, which easily generates air bubbles. These air bubbles, when mixed directly with the goat milk, can easily cause oxidation and spoilage, affecting product quality. In addition, the lid needs to be opened when pouring out the milk, which can also easily allow air to enter and cause the goat milk to spoil.
[0004] Based on the above problems, we provide a bottom-in, bottom-out goat milk storage tank with a loading and unloading structure. Summary of the Invention
[0005] To address the problems mentioned in the background art, this application provides a bottom-in, bottom-out feeding structure for a goat milk storage tank.
[0006] The loading and unloading structure of the bottom-in, bottom-out goat milk storage tank provided in this application adopts the following technical solution: A bottom-in, bottom-out goat milk storage tank loading and unloading structure includes: a tank body, the tank body comprising an outer shell and an inner insulation layer, the inner insulation layer having a storage area, and further comprising: The flexible discharge assembly includes an inverted conical soft membrane, the periphery of which is sealed to the bottom of the inner insulation layer, and the top of which forms a conical discharge port extending into the storage area. An adjustment assembly includes a lead screw mounted on the top of the tank, the lower end of which extends into the tank and passes through a conical outlet of the diaphragm, the height of which is changed by adjusting the lead screw.
[0007] In some embodiments, the flexible discharge assembly further includes a collection trough located below the soft membrane, the bottom of the collection trough having a discharge nozzle, and the top of the collection trough being sealed to the bottom of the inner insulation layer.
[0008] In some embodiments, the adjusting assembly further includes a bushing and an open ring, the bushing being threaded onto the lead screw, the open ring being fixedly sleeved outside the bushing, and a discharge port being formed between the bushing and the open ring; The opening ring is fixedly connected to the inner wall of the conical discharge port of the soft membrane.
[0009] In some embodiments, the outer periphery of the opening ring is provided with a wedge-shaped protrusion, and the inner wall of the conical discharge port of the soft membrane is provided with a limiting groove that engages with the wedge-shaped protrusion.
[0010] In some embodiments, the membrane is made of food-grade silicone rubber material and its surface is treated with a fluorocarbon coating.
[0011] In some embodiments, the top of the tank is provided with a cap, and the inner top surface of the cap is provided with a flexible sealing block. When the conical discharge port of the soft membrane is raised to the highest position, the upper end of the conical discharge port is sealed and engaged with the flexible sealing block.
[0012] In some embodiments, a magnetic ring is embedded within the flexible sealing block; The soft membrane is also embedded with multiple support rings, and at least one support ring is installed at the conical discharge port of the soft membrane, and the support ring and the magnetic ring are magnetically attracted to each other.
[0013] In some embodiments, an annular cavity is further provided in the inner insulation layer, and the annular cavity is filled with dry gas.
[0014] In some embodiments, the cover is also provided with a vent valve, which includes a vent pipe that penetrates the cover and a plug threaded into the vent pipe. The plug is hollow inside and has a vent hole on its inner wall at the top.
[0015] In some embodiments, a support is also installed at the bottom of the tank, on which a hand pump is mounted. A conveying pipe is installed at the outlet of the hand pump. The conveying pipe passes through the top of the inner insulation layer, is inserted into the storage area, and extends downward along the inner wall for a period of time. A flexible pipe for easy material receiving is also connected to the inlet of the hand pump.
[0016] In summary, in the technical solution of this application embodiment, the height of the conical discharge port of the soft membrane can be changed by the threaded engagement of the lead screw and the bushing. When the height of the conical discharge port drops below the liquid surface, the goat milk in the storage area can enter the collection tank and be discharged through the discharge nozzle. When the conical discharge port rises to the highest point, it can also cooperate with the flexible sealing block to maintain the seal of the storage area, effectively delaying the deterioration of the goat milk.

[0021] It should be noted that the accompanying drawings are schematic and not to scale.

Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.
[0022] In related technologies, traditional milk storage tanks only have an opening at the top for feeding and discharging. When goat milk flows in from a height, it has a large contact area with air, which easily generates bubbles. These bubbles, when directly mixed in with the goat milk, can easily cause the goat milk to oxidize and deteriorate, affecting product quality. In addition, when pouring out the milk, the lid of the opening needs to be opened, which can also easily allow air to enter and cause the goat milk to spoil. Reference Figures 1 to 4 As shown, the loading and unloading structure of the milk storage tank in this application mainly includes a tank body 1, a flexible discharge component 11, and an adjustment component 12; In this embodiment of the application, the tank 1 is the main container for storing goat milk. It adopts a double-layer structure to ensure the heat preservation effect. The outer layer is a metal shell 101, which plays a protective and support role. The inner layer is an inner heat preservation layer 103, which is usually made of food-grade stainless steel. The interior of the tank forms a storage area for storing goat milk. The bottom of the storage area is provided with a gradually narrowing opening to guide the goat milk to slide down and be discharged. To further optimize the insulation effect, an annular cavity 1031 surrounding the storage area is provided in the inner insulation layer 103. The bottom of the annular cavity 1031 and the outer shell 101 together form a closed interlayer. In the final stage of tank assembly, dry inert gas (such as nitrogen or dry air) is filled into the annular cavity 1031 through a special valve and then sealed. Since the thermal conductivity of dry gas is much lower than that of humid air, it can effectively reduce heat conduction through the tank wall. In this embodiment of the application, the flexible discharge assembly 11 includes a soft membrane 1101 made of flexible material and in the shape of an inverted cone; Specifically, the bottom edge of the soft membrane 1101 (i.e., the large conical end) is sealed to the inner bottom of the inner insulation layer 103 by means of a sealing ring or hot-melt welding. The top of the soft membrane 1101 (i.e., the small conical end) tapers upward to form a conical discharge port. This conical discharge port extends upward and is suspended in the storage area. In the storage state, the conical discharge port is suspended above the surface of the goat milk liquid. When discharge is required, the conical discharge port is slid down to below the liquid surface. Under the action of gravity, the goat milk will flow through the conical discharge port and be discharged downward. In this embodiment of the application, the adjustment component 12 includes a vertically installed lead screw 1201; Specifically, the lead screw 1201 is rotatably mounted at the top center of the tank 1 via bearings and seals, with its lower end extending into the internal space of the tank and passing through the conical discharge port of the soft membrane 1101. Its bottom end is connected to the discharge nozzle 1103 via a bearing bracket. In addition, the top of the lead screw 1201 is located outside the tank and is equipped with a handwheel or knob for easy manual operation. During operation, when feeding is required, the operator rotates the knob on the top of the lead screw 1201. The lead screw 1201 rotates and cooperates with the bushing 1202 to lift the conical discharge port of the soft membrane 1101 connected to it upward, so that the conical discharge port is always above the surface of the goat milk, thus storing the goat milk in the tank 1. When discharging is required, the lead screw 1201 is rotated in the opposite direction, and the corresponding conical discharge port will slide downward. When it is below the surface of the goat milk, the goat milk will flow downward through the conical discharge port under the influence of gravity, thus completing the discharge.
[0023] To further guide the goat milk, prevent dripping, and facilitate discharge from tank 1, refer to Figure 2 , Figure 4 As shown, the flexible discharge assembly 11 also includes a material collection trough 1102 disposed directly below the soft membrane 1101; Specifically, the material collection trough 1102 is also in the shape of an inverted cone or a bowl. Its top edge is sealed to the bottom outer side of the inner insulation layer 103 through a flange and a sealing gasket, thereby forming a closed collection cavity under the soft membrane 1101. A conical discharge nozzle 1103 extends downward from the bottom center of the material collection trough 1102 and is connected to it. The discharge nozzle 1103 is used to directly discharge material into the receiving container. During operation, when the conical outlet of the soft membrane 1101 descends below the surface of the goat milk, the flowing goat milk will flow into the collection trough 1102 below. The collection trough 1102 collects all the flowing milk and guides it to the central outlet 1103, avoiding pollution and waste caused by the milk flowing along the bottom outer wall of the tank 1. At the same time, the outlet 1103 can directly discharge the milk into the receiving container below, allowing the operator to intuitively control the amount of milk discharged, making it more convenient and reliable.
[0024] Reference Figure 4 , Figure 6 As shown, the adjusting assembly 12 also includes a bushing 1202 and an open ring 1203. The bushing 1202 has an internal thread at its center, and its thread is sleeved on the lead screw 1201. Specifically, the open ring 1203 is a ring-shaped component with an opening in the middle, which is fixedly sleeved on the outside of the bushing 1202. The outer side of the bushing 1202 is connected to the inner wall of the open ring 1203 by multiple connecting rods, so that multiple discharge ports 1204 are formed between the two, so that goat milk can flow down through the discharge ports 1204. Furthermore, the ring body of the open ring 1203 is fixedly connected to the inner wall of the conical discharge port of the soft diaphragm 1101 by means of bonding, snap-fit or interference fit. Therefore, when the lead screw 1201 rotates, the bushing 1202 is threaded to it and is restricted from rotating by the open ring 1203 and the soft diaphragm 1101. The bushing 1202 will move up and down in a straight line together with the open ring 1203 and the conical discharge port fixed to it, so as to facilitate the adjustment of the height.
[0025] To ensure a secure and reliable connection between the diaphragm 1101 and the open ring 1203 during frequent lifting and lowering operations, refer to... Figure 6 As shown, a wedge-shaped protrusion 1205 is machined on the outer circumferential surface of the opening ring 1203. Correspondingly, a limiting groove that perfectly matches the shape of the wedge-shaped protrusion 1205 is formed inside the conical discharge port of the soft film 1101 by molding or secondary forming. During assembly, the conical outlet of the soft membrane 1101 is fitted onto the opening ring 1203, and the wedge-shaped protrusion 1205 is fully embedded in the limiting groove. This locking structure has two major advantages: first, mechanical interlocking, which can effectively prevent the soft membrane from falling off the opening ring 1203 under the action of milk rinsing or its own gravity; second, enhanced sealing, the wedge structure causes the soft membrane material to undergo elastic deformation at the protrusion, forming a tighter fit, enhancing the sealing of the joint, and preventing milk from leaking from the seam.
[0026] Reference Figure 4 As shown, the soft membrane 1101 is integrally molded from food-grade silicone rubber material through a molding process. Food-grade silicone rubber has the advantages of being non-toxic, odorless, chemically stable, resistant to high and low temperatures (-60℃ to 200℃), and physiologically inert, and fully complies with the safety standards for food contact materials. To further enhance performance, after the soft membrane 1101 is formed, its inner and outer surfaces that come into contact with milk are treated with a fluorocarbon coating. This treatment, achieved through spraying or dipping, forms a dense fluoropolymer film on the silicone rubber surface, making it difficult for water and fat from sheep milk to adhere. During discharge, the milk can quickly roll off like water droplets on a lotus leaf, achieving a "no-sticking" effect and significantly reducing residue. During cleaning, only a small amount of water or detergent is needed to easily rinse it clean, greatly reducing cleaning difficulty and hygiene risks. In addition, this coating also improves the wear resistance and aging resistance of the soft membrane 1101 surface, extending its service life in environments with frequent use and cleaning.
[0027] Reference Figure 3 , Figure 5 As shown, a cap 102 is also provided on the top of the tank 1. A flexible sealing block 1021 is fixedly installed at the center of the inner wall of the cap 102. The sealing block can be made of food-grade rubber or silicone. During operation, when goat milk needs to be stored or transported for a long time, the conical outlet of the soft membrane 1101 is raised to the highest position by adjusting component 12. At this time, the upper end of the conical outlet can be tightly pressed into the bottom of the flexible sealing block 1021. The flexible sealing block 1021 can wrap around the edge of the conical outlet to form a reliable composite seal, which can effectively prevent the problem of goat milk oxidation and deterioration during storage or transportation. In addition, during daily use, the sealing cooperation between the conical outlet and the flexible sealing block 1021 can also delay the deterioration of goat milk. Furthermore, to ensure that the conical discharge port accurately and stably aligns with and adheres tightly to the top flexible sealing block 1021 when raised to its highest position, a magnetic ring 1022 is embedded around the center inside the flexible sealing block 1021. The magnetic ring 1022 is made of permanent magnet material. At the same time, multiple support rings 1104 are embedded at intervals along the axial direction inside the wall of the soft membrane 1101. These support rings are made of magnetic metal material that can be attracted by a magnet. Their main function is to maintain the conical shape of the soft membrane 1101 and prevent it from deforming excessively under milk pressure. In addition, at least the topmost support ring 1104 is precisely positioned at the conical discharge port of the soft membrane 1101. When the conical discharge port rises to its highest position, the support ring 1104, in cooperation with the magnetic ring 1022, drives the conical discharge port to adhere tightly to the bottom of the flexible sealing block 1021, forming an effective seal.
[0028] To maintain pressure balance inside the tank during storage and discharge, refer to Figure 2 , Figure 7 As shown, a vent valve 104 is installed on the cover 102; Specifically, the vent valve 104 includes a vent pipe 1041 that penetrates the cover 102 vertically. The vent pipe 1041 has internal threads. A hollow cylindrical plug 1042 is screwed into the vent pipe 1041 through the threads on its outer wall. A tiny vent hole 1043 is opened on the inner wall of the top of the plug 1042. During operation, when the stopper 1042 is fully tightened, the vent 1043 is pressed inside the vent pipe 1041, thus maintaining the seal inside the storage area. When the stopper 1042 is screwed upward to expose the vent 1043, the air pressure inside the storage area can always be balanced with the external air pressure, thus facilitating the feeding and discharging of goat milk.
[0029] Reference Figure 1 , Figure 3 As shown, a bracket 2 is fixedly installed at the bottom of the tank 1 to stably support the entire storage tank and leave operating space at the bottom. On one side of the bracket 2, a hand pump 21 is also installed. The outlet of the hand pump 21 is connected to a conveying pipe 211 through a pipe. Specifically, the conveying pipe 211 is inserted into the storage area from the top of the inner insulation layer 103 and extends downward along the inner wall of the inner insulation layer 103 until it is close to the bottom of the tank. The inlet of the hand pump 21 is connected to a flexible suction pipe, which is convenient to insert into the source container such as the milk bucket. During operation, the operator can draw goat milk from containers such as milk buckets by shaking the hand pump 21, and release it into the storage area through the feed pipe 211. The feed pipe 211, which extends downward along the inside of the inner insulation layer 103, can minimize the violent impact and splashing of the milk when it falls with the air, thereby reducing the risk of foaming and fat oxidation, which is conducive to maintaining the quality of goat milk and increasing storage time.
