Description

Technical Field

[0001] This utility model belongs to the field of feed-grade lard storage technology, specifically relating to a feed-grade lard storage device with an ultrasonic liquid level detection mechanism. Background Technology

[0002] Feed is a general term for the food raised by all animals. In a narrower sense, feed mainly refers to the food raised in agriculture or animal husbandry. Lard is an indispensable additive in the feed production process. The refining process of feed-grade lard involves heating pork, releasing fat, separating oil and fat, removing impurities, and finally storing the lard. The storage of feed-grade lard directly affects the quality stability and market supply capacity of the product. However, existing lard storage devices are generally ordinary storage tanks, which leads to an uncontrollable storage environment and is prone to oxidative rancidity. Due to the increase of storage sediment, the quality and safety of feed-grade lard are affected. Therefore, there is an urgent need for a feed-grade lard storage device with an ultrasonic liquid level detection mechanism to solve the above problems. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a feed-grade lard storage device with an ultrasonic liquid level detection mechanism.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A feed-grade lard storage device with an ultrasonic liquid level detection mechanism includes an oil storage tank. A tank cover is installed on the top of the tank cover, and an oil inlet pipe is located on the top of the cover. A detection pipe is installed on one side of the top of the cover, extending its bottom into the oil storage tank and positioned above the bottom inner side. An ultrasonic liquid level sensor is installed on the top of the detection pipe. A low-oxygen gas filling pipe and an antioxidant addition pipe, both connected to the oil storage tank, are also installed on the top of the cover. A sealing valve is installed at the input end. An oxidation sensor is installed on the top inner side of the barrel lid. Several temperature sensors are installed on the inner side of the oil storage tank. A temperature control box is installed on the outer side of the oil storage tank. The bottom of the barrel lid is installed inside the temperature control box and is sealed to the oil storage tank. The temperature control box has a cavity. Water inlet pipes and water outlet pipes connected to the cavity are provided on the upper and lower sides of the temperature control box. An electric heating wire is installed in the cavity. An oil outlet pipe is connected to the bottom of the oil storage tank. The bottom of the oil outlet pipe passes through the temperature control box and extends to its lower side.

[0006] Furthermore, several of the aforementioned temperature sensors are evenly arranged in an array and mounted on the bottom and side walls of the oil storage tank. This structural design can significantly improve the efficiency and accuracy of temperature sensor monitoring.

[0007] Furthermore, the temperature control box has hinge seats installed on both sides of its top, and connecting rods are connected to the hinge seats. An adapter plate is installed on the top of the connecting rods, and a threaded hole is provided on one side of the adapter plate. A threaded rod is connected to the threaded hole, a torsion block is installed on the top of the threaded rod, and a pressing block is installed on the bottom of the threaded rod. Pressing recesses are installed on both sides of the top of the lid at corresponding pressing blocks. This structural design facilitates the limiting and fixing of the lid, improving the sealing performance at the connection between the oil storage tank and the lid.

[0008] Furthermore, a sealing seat is installed at the penetration point of the oil outlet pipe within the cavity. This structural design prevents liquid leakage within the cavity.

[0009] Furthermore, sealing end caps are installed at both the input and output ends of the oil inlet and outlet pipes. This structural design prevents air from entering.

[0010] Furthermore, the temperature control box is equipped with I-beam-shaped support frames on both sides of its bottom. This structural design provides stable support and also allows the temperature control box and oil storage tank to be moved and used by mounting them on a mobile device.

[0011] The beneficial effects of this invention are as follows: This invention uses an ultrasonic liquid level sensor to dynamically monitor the storage volume of lard, preventing overflow of feed-grade lard and waste of storage space. A temperature sensor collects temperature data in real time from different storage tank areas to ensure that the temperature fluctuations inside the storage tank are maintained within the optimal range. An antioxidant is added through an antioxidant addition tube to dynamically adjust the antioxidant, and a low-oxygen gas filling tube is filled with low-oxygen gas, which reduces the contact between the oil and oxygen, slows down the oxidation reaction rate, and, combined with an oxidation sensor, accurately assesses the degree of oil oxidation and monitors the oxidation state of lard in real time, thereby improving the storage safety of the oil.

The top of the storage tank 1 is fitted with a lid 2, and the lid 2 has an oil inlet pipe 3. A detection pipe 4 is installed on one side of the top of the lid 2, extending its bottom into the storage tank 1 and located on the upper inner bottom side of the storage tank 1. An ultrasonic liquid level sensor 5 is installed on the top of the detection pipe 4. The lid 2 also has a low-oxygen gas filling pipe 6 and an antioxidant addition pipe 7 connected to the storage tank 1. An ultrasonic liquid level sensor 5 is installed at the input end of the low-oxygen gas filling pipe 6 and the antioxidant addition pipe 7. There is a sealing valve 8, an oxidation sensor 9 is installed on the top inner side of the barrel cover 2, several temperature sensors 10 are installed on the inner side of the oil storage tank 1, a temperature control box 11 is installed on the outer side of the oil storage tank 1, the bottom of the barrel cover 2 is installed in the temperature control box 11 and is sealed to the oil storage tank 1, the temperature control box 11 has a cavity 12, the upper and lower sides of the temperature control box 11 are provided with water inlet pipe 13 and water outlet pipe 14 connected to the cavity 12, an electric heating wire 15 is installed in the cavity 12, and the bottom of the oil storage tank 1 is connected to an oil outlet pipe 16, the bottom of the oil outlet pipe 16 passes through the temperature control box 11 and extends to its lower side.

[0020] Preferably, a plurality of temperature sensors 10 are evenly arranged in an array on the bottom and side walls of the oil storage tank 1. This structural design can significantly improve the efficiency and accuracy of temperature sensor 10 monitoring. In practice, other arrangement structures of temperature sensor 10 can also be considered depending on the specific circumstances.

[0021] Preferably, hinge seats 17 are installed on both sides of the top of the temperature control box 11. Connecting rods 18 are connected to the hinge seats 17. An adapter plate 19 is installed on the top of the connecting rods 18. A threaded hole 20 is provided on one side of the adapter plate 19. A threaded rod 21 is connected inside the threaded hole 20. A torsion block 22 is installed on the top of the threaded rod 21, and a pressing block 23 is installed on the bottom of the threaded rod 21. Pressing recesses 24 are installed on both sides of the top of the lid 2 at corresponding pressing blocks 23. This structural design facilitates the limiting and fixing of the lid 2, improving the sealing at the connection between the oil storage tank 1 and the lid 2. In practice, other fixing and installing structures for the lid 2 can also be considered depending on the specific circumstances.

[0022] Preferably, a sealing seat 25 is installed at the penetration point of the oil outlet pipe 16 in the cavity 12. This structural design prevents liquid leakage within the cavity 12. In practice, other sealing structures for the oil outlet pipe 16 can also be considered depending on the specific circumstances.

[0023] Preferably, sealing end caps 26 are installed at both the inlet and outlet ends of the oil inlet pipe 3 and the oil outlet pipe 16. This structural design prevents air from entering. In practice, other structural shapes of the sealing end caps 26 can also be considered depending on the specific circumstances.

[0024] Preferably, I-beam-shaped support frames 27 are installed on both sides of the bottom of the temperature control box 11. This structural design provides stable support and also allows the temperature control box 11 and the oil storage tank 1 to be moved and used, as the I-beam-shaped support frames 27 can be installed on a mobile device. In practice, other support and mounting structure shapes for the temperature control box 11 can also be considered depending on the specific circumstances.

[0025] In this embodiment, when feed-grade lard is fed into the storage tank 1 through the inlet pipe 3, the detection area is reduced by the detection pipe 4, allowing the ultrasonic level sensor 5 to more accurately monitor the lard storage volume dynamically. This optimizes the filling of feed-grade lard into the storage tank 1, preventing overflow and waste of storage space. Simultaneously, a dynamically regulated antioxidant is added to the storage tank 1 through the antioxidant addition pipe 7, and low-oxygen gas is filled into the storage tank 1 through the low-oxygen gas filling pipe 6. This reduces the contact between the oil and oxygen, slows down the oxidation reaction rate, and complements the oxidation process. Sensor 9 accurately assesses the degree of oil oxidation and monitors the oxidation state of lard in real time, improving the storage safety of oil. At the same time, temperature sensor 10 collects temperature data of different areas of oil storage tank 1 in real time to ensure that the temperature fluctuation inside oil storage tank 1 is maintained within the optimal range. When the temperature inside oil storage tank 1 is too high, cold water is supplied to the cavity 12 through the water inlet pipe 13 and flows out through the water outlet pipe 14 to cool it down. When the temperature inside oil storage tank 1 is too low, the electric heating wire 15 can be activated to heat and keep it warm, so that the temperature inside oil storage tank 1 can be maintained within the optimal range, avoiding accelerated local oxidation due to uneven temperature.

[0026] When not in use, both the oil inlet pipe 3 and the oil outlet pipe 16 are fitted with sealing end caps 26 to prevent air from entering the oil storage tank 1.

[0027] During installation, the temperature control box 11 is first fixed, and then the oil storage tank 1 is installed into the temperature control box 11. At this time, the top surface of the oil storage tank 1 is lower than the top surface of the temperature control box 11. Then, the lid 2 is installed into the temperature control box 11 and placed on the surface of the oil storage tank 1. At this time, the temperature control box 11 can reduce the entry of air. Finally, the connecting rod 18 is rotated to a vertical state, and the torsion block 22 is rotated so that the torsion block 22 drives the threaded rod 21 to rotate along the threaded hole 20 and move downward along the threaded hole 20 to push the pressing block 23 into the pressing recess 24 on the top of the lid 2, thereby fixing and pressing the lid 2, ensuring the stable installation of the lid 2 and reducing the entry of air.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
