Description

Technical Field

[0001] This utility model relates to the field of handling diseased and dead animals, and specifically to an oil storage tank for storing animal oil. Background Technology

[0002] Currently, diseased and dead animals are mainly disposed of through incineration, rendering, burial, or other physical, chemical, and biological methods to completely eliminate the pathogens they carry, thereby eliminating disease factors and ensuring the health and safety of humans and animals. Among these methods, rendering is the most advanced and efficient process. After rendering, the resulting lard is typically stored in lard storage tanks for the following reasons: The rendered lard may still contain small amounts of impurities and microorganisms. The storage tanks provide a relatively sealed and stable environment, preventing external contamination during storage, avoiding oxidation, spoilage, and corrosion by harmful microorganisms, ensuring stable quality, and preventing secondary environmental pollution. The rendering process is continuous. The lard storage tanks, as an intermediate step, temporarily store the lard, acting as a buffer to ensure the smooth operation of subsequent processing and transportation, preventing production stoppages due to mismatches between processes and ensuring the continuity of the rendering production line. Heating lard storage tanks can prevent the lard from solidifying at low temperatures, maintain its fluidity, and facilitate subsequent transportation and processing; stirring can prevent impurities from settling in the lard, make the lard composition uniform, ensure quality, slow down the lard oxidation rate, and extend the storage period.

[0029] The zoned heating coil 2 includes a spiral coil 21, a return pipe 22, and several electrically controlled reversing valves 23 and reversing pipes 24. The bottom of the spiral coil 21 is connected to the heating source inlet 201, the bottom of the return pipe 22 is connected to the heating source outlet 202, and the top of the spiral coil 21 is connected to the return pipe 22. The electrically controlled reversing valve 23 is installed on the spiral coil 21, and the two ends of the reversing pipe 24 are connected to the electrically controlled reversing valve 23 and the return pipe 22, respectively. The electrically controlled reversing valve 23 and the reversing pipe 24 divide the spiral coil 21 vertically into several heating zones 203.

[0030] The bottom of the spiral coil 21 is located above the inspection hole 17, and an inspection area 204 is provided between the bottom of the spiral coil 21 and the bottom of the tank body 1.

This achieves the effect of different heating zones responding to different oil levels, improving energy efficiency. Furthermore, the temperature sensor and heating source circulation pump effectively maintain the tank temperature, achieving excellent oil preservation.
