[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1-4 This embodiment provides the following technical solution: a slag oil tank for bone oil processing with oil residue separation, including a tank body 1, a jacket 2 fixedly sleeved on the outside of the tank body 1, a stirrer rotatably connected inside the tank body 1, and a slag discharge pipe penetrating the jacket 2 provided at the bottom inside the tank body 1.

[0018] Furthermore, the top of tank 1 is equipped with an inspection port with a sealed cover and an exhaust valve; the side wall of tank 1 is provided with an upper oil outlet, a middle feed inlet, and a lower slag discharge outlet from top to bottom; these interfaces respectively realize the functions of material inlet and outlet, impurity discharge and equipment maintenance, ensuring the continuous operation of the separation process.

[0019] The jacket 2 is fixedly connected to the lower partition 4 and the upper partition 5. The lower partition 4 and the bottom wall inside the jacket 2 form a bottom heating cavity 6. The bottom heating cavity 6 is fixedly connected to a vortex heat-conducting plate 7 that fits against the bottom of the tank 1, which is used to make the steam flow along the vortex channel. A middle heating chamber 8 is formed between the lower partition 4 and the upper partition 5, and a top heating chamber 9 is formed between the upper partition 5 and the top wall inside the jacket 2. The bottom heating chamber 6, the middle heating chamber 8, and the top heating chamber 9 are independently supplied with steam and temperature regulated to meet the temperature requirements of different layers of materials in the tank 1, avoid local overheating or insufficient heating, and improve the oil residue separation efficiency and oil purity.

[0020] Both the upper partition 5 and the lower partition 4 have several pressure balance holes distributed around their circumference. Each pressure balance hole is equipped with a one-way valve core. When the pressure in one of the bottom heating chamber 6, the middle heating chamber 8, or the top heating chamber 9 is too high, the one-way valve will automatically open to release pressure, thus preventing the backflow of steam from interfering with other chambers.

[0021] Spiral heat-conducting plates 10, which are attached to the side wall of the tank 1, are fixedly connected to both the middle heating chamber 8 and the top heating chamber 9. These plates are used to guide the steam along the spiral flow channel. The spiral heat-conducting plates 10, which are attached to the side wall of the tank 1, are fixedly connected to both the middle heating chamber 8 and the top heating chamber 9. These plates are used to guide the steam entering the bottom heating chamber 6, the middle heating chamber 8, and the top heating chamber 9, so as to better exchange heat with the material in the tank 1. This also increases the heat exchange area and improves the heat exchange efficiency of the material in the tank 1.

[0022] It also includes a steam supply device for supplying steam to the bottom heating chamber 6, the middle heating chamber 8 and the top heating chamber 9. The steam supply device includes a supply manifold 11, and the inlet of the supply manifold 11 is connected to a steam device, so that the steam in the steam device enters the supply manifold 11 and the amount of steam discharged into the supply manifold 11 is regulated by a flow regulating valve on the steam device.

[0023] The main supply pipe 11 is connected to a first steam pipe 12 and two second steam pipes 13. The outlet of the first steam pipe 12 is connected to the inlet of the bottom heating chamber 6, and the outlets of the two second steam pipes 13 are respectively connected to the corresponding inlets of the middle heating chamber 8 and the top heating chamber 9. Through the first steam pipe 12 and the second steam pipe 13, steam can enter the bottom heating chamber 6, the middle heating chamber 8 and the top heating chamber 9 to exchange heat with the material in the tank 1.

[0024] In some embodiments, a first steam pipe 12 is disposed on the lower part of the side wall of the bottom heating chamber 6, and one second steam pipe 13 is disposed on the lower part of the side wall of the middle heating chamber 8, with the outlet of the second steam pipe 13 corresponding to the inlet of the spiral flow channel. Another second steam pipe 13 is disposed on the lower part of the side wall of the top heating chamber 9, with the outlet of the second steam pipe 13 corresponding to the inlet of the spiral flow channel. The positions of the outlet of the first steam pipe 12 and the outlet of the second steam pipe 13 can be adjusted according to actual gas supply requirements.

[0025] Each of the first steam pipe 12 and the two second steam pipes 13 is equipped with a first electric regulating valve, which can independently adjust the steam supply of each chamber of the bottom heating chamber 6, the middle heating chamber 8 and the top heating chamber 9 through the PLC control system, so as to achieve precise control of the heating temperature of different areas.

[0026] It also includes a steam recovery device for recovering the steam discharged from the bottom heating chamber 6, the middle heating chamber 8 and the top heating chamber 9. The steam recovery device includes a recovery main pipe 14, the outlet of which is connected to a heat exchange device. Through the heat exchange device, the heat in the recovered steam can be recovered and utilized.

[0027] The main recovery pipe 14 is connected to a first recovery pipe 15 and two second recovery pipes 18. A first gas collecting hood 16 is fixedly connected to the air inlet of the first recovery pipe 15. A guide bucket 17 is fixedly connected to the air inlet of the first gas collecting hood 16. The guide bucket 17 is fixedly sleeved on the outside of the drain pipe 3 and communicates with the bottom heating chamber 6. The air inlets of the two second recovery pipes 18 are fixedly connected to second gas collecting hoods 19. The air inlets of the two second gas collecting hoods 19 are respectively connected to the corresponding air outlets on the middle heating chamber 8 and the top heating chamber 9. By setting the first gas collecting hood 16 and the second gas collecting hood 19, it is convenient for the steam after heat exchange to enter the interior of the first recovery pipe 15 and the second recovery pipe 18, so as to uniformly recover and process the steam after heat exchange.

[0028] The first recovery pipe 15 and the two second recovery pipes 18 are each equipped with a second electric regulating valve and a pressure valve. The second electric regulating valve and pressure valve can prevent the steam backflow caused by excessive pressure in the first recovery pipe 15 and the two second recovery pipes 18. The second electric regulating valve can adjust the steam recovery flow rate and work with the heat exchange equipment to achieve efficient heat recovery.

[0029] In some embodiments, the diversion hopper 17 is connected to the bottom heating chamber 6 and fixedly sleeved on the outside of the drain pipe 3, and the diversion hopper 17 has an oblique conical structure. The first gas collecting hood 16 is fixedly connected to one side of the diversion hopper 17 and connected to the diversion hopper 17, which is beneficial for collecting the steam after it flows along the vortex channel. One of the second gas collecting hoods 19 is fixedly connected to the top of the side wall of the middle heating chamber 8, and the other second gas collecting hood is fixedly connected to the top of the side wall of the top heating chamber 9, which is beneficial for collecting the steam after it flows along the spiral channel.

[0030] It also includes a condensate drainage device for draining condensate from the bottom heating chamber 6, the middle heating chamber 8, and the top heating chamber 9. The condensate drainage device includes a first drain valve 20 and two second drain valves 22. The inlet of the first drain valve 20 is fixedly connected to a first water collection cover 21, which is connected to the drain outlet on the diversion bucket 17. The inlets of the two second drain valves 22 are fixedly connected to second water collection covers 23, which are connected to the corresponding drain outlets on the middle heating chamber 8 and the top heating chamber 9, respectively. Through the first drain valve 20 and the second drain valve 22, the condensate drained from the bottom of the bottom heating chamber 6, the middle heating chamber 8, and the top heating chamber 9 can be drained. Filter screens are provided at the drain outlets of the bottom heating chamber 6, the middle heating chamber 8, and the top heating chamber 9 to prevent impurities from clogging the valves. Furthermore, both the first drain valve 20 and the second drain valve 22 are electric shut-off valves, which can be automatically opened for drainage by a PLC system at regular intervals or based on liquid level sensor signals.

[0031] In some embodiments, a condensate main pipe can also be provided, and the outlets of the first drain valve 20 and the second drain valve 22 can be connected to the condensate main pipe for unified collection and treatment of condensate.

[0032] In some embodiments, the bottom wall of the vortex heat-conducting plate 7 is provided with a plurality of spaced drainage holes 24. Through the drainage holes 24, the condensate in the vortex flow channel can flow quickly into the bottom of the bottom heating cavity 6, which is beneficial for the discharge of condensate in the bottom heating cavity 6.

[0033] In some embodiments, the spiral heat-conducting plate 10 is provided with a guide groove 25 along the spiral upward direction. Through the guide groove 25, the condensate in the spiral flow channel can be quickly discharged from the middle heating chamber 8 and the top heating chamber 9, preventing the condensate from lingering on the surface of the spiral guide plate.

[0034] The working principle of this utility model is as follows: After the material enters the tank 1, the feeding pipe is closed; High-temperature steam generated by external steam equipment enters the supply main pipe 11 and is then distributed to the first steam pipe 12 and two second steam pipes 13. The first steam pipe 12 delivers the steam to the bottom heating chamber 6. After entering the bottom heating chamber 6, the steam is guided by the vortex heat conduction plate 7 inside the bottom heating chamber 6 and flows along the vortex flow channel close to the bottom of the tank 1. During the steam flow, the steam heat is quickly transferred to the bottom of the bone oil in the tank 1, so as to achieve uniform preheating of the bottom of the bone oil. Two second steam pipes 13 respectively deliver steam to the middle heating chamber 8 and the top heating chamber 9. After the steam enters the middle heating chamber 8 and the top heating chamber 9, it flows upward along the spiral flow channel of the spiral heat-conducting plate 10 inside the middle heating chamber 8 and the top heating chamber 9, closely adhering to the side wall of the tank body 1. The heat is transferred to the middle and top areas of the bone oil inside the tank body 1 through the spiral heat-conducting plate 10, forming a "full tank coverage" heating effect in conjunction with bottom heating. If the temperature at the bottom of the bone oil is too low, the temperature sensor at the bottom of the tank 1 will detect this and increase the opening of the first electric regulating valve to increase the steam supply to the bottom heating chamber 6 and raise the bottom heating temperature. If the temperature in the middle or top of the bone oil is insufficient, the electric regulating valve of the corresponding second steam pipe 13 is adjusted in the same way to achieve precise stratified control of the bone oil temperature in the tank 1. Uncondensed steam in the bottom heating chamber 6 enters the diversion hopper 17 along with the condensate. After passing through the diversion hopper 17, the steam enters the first gas collection hood 16 of the first recovery pipe 15, and is then transported to the recovery main pipe 14 through the first recovery pipe 15. The uncondensed steam from the middle heating chamber 8 and the top heating chamber 9 rises along the spiral flow channel to the top of the chambers of the middle heating chamber 8 and the top heating chamber 9, and then enters the second gas collection hood 19 of the second recovery pipe 18, and then flows into the recovery main pipe 14 through the second recovery pipe 18. The condensate in the bottom heating chamber 6 flows rapidly into the bottom of the bottom heating chamber 6 along the drain hole 24 of the vortex heat conduction plate 7, and then gathers into the diversion bucket 17. It is then discharged through the first drain valve 20 connected to the bottom of the diversion bucket 17. The first drain valve 20 is controlled by the PLC system and can be set to drain at a time, or to automatically drain when the liquid level reaches the set height according to the liquid level sensor signal in the diversion bucket 17. The condensate from the middle heating chamber 8 and the top heating chamber 9 flows along the guide groove 25 of the spiral heat-conducting plate 10 to the bottom of the chambers of the middle heating chamber 8 and the top heating chamber 9, and finally collects at the drain outlet at the bottom of the chambers of the middle heating chamber 8 and the top heating chamber 9. It is then discharged through the second drain valve 22, which is connected to the drain outlet at the bottom of the chambers of the middle heating chamber 8 and the top heating chamber 9. The drainage logic is the same as that of the first drain valve 20, ensuring that the condensate is discharged in time and does not affect the contact efficiency between the steam and the heat-conducting plate.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
