Description

Technical Field

[0001] This utility model relates to the field of conveying and degassing technology, and in particular to an integrated vacuum conveying and degassing device for animal oil. Background Technology

[0002] In the processing of animal fats (such as lard, tallow, and mutton fat), from the completion of melting to the final packaging, multiple processes are required, including transportation, deodorization (degassing), and filtration. Animal fats contain easily oxidized unsaturated fatty acids, which are highly susceptible to rancidity when exposed to air at high temperatures, affecting flavor and shelf life. Simultaneously, small odor molecules present in the fats (such as aldehydes and ketones) must also be effectively removed to improve product quality.

[0003] Currently, traditional processing methods typically employ segmented equipment: first, molten oil is pumped from an open or simply sealed container to a temporary storage tank, then transferred to a dedicated deodorization tank for degassing under vacuum conditions, and finally purified by a filtration device. This segmented processing mode has the following significant drawbacks: the material needs to be transferred, heated, and kept warm between multiple independent devices, resulting in severe heat loss, a long overall process time, high energy consumption, and low production efficiency. Therefore, we propose an integrated vacuum conveying and degassing device for animal oil. Utility Model Content

[0004] The main objective of this invention is to provide an integrated vacuum conveying and degassing device for animal oil, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An integrated vacuum conveying and degassing device for animal oil includes a storage tank and a receiving tank. A filter box is connected to one side of the receiving tank. The filter box has symmetrically arranged slots on its surface, and filter plates are inserted into the slots. A limiting groove is formed on one side of each filter plate. A movable groove is formed on one side of the inner wall of each slot. A sliding groove is formed on one side of the inner wall of the movable groove. A positioning rod is inserted into the sliding groove. A limiting block is provided at one end of the positioning rod. A spring is sleeved on the periphery of the positioning rod. A vacuum pump is connected to one side of the filter box. A cavity is formed inside the storage tank. A heating wire is sleeved on the inner wall of the cavity. A liquid inlet is connected to one side of the inner wall of the cavity. A discharge pipe is connected to the bottom surface of the storage tank, and a valve is connected to the surface of the discharge pipe.

[0006] Preferably, one end of the discharge pipe is fixedly connected to one side of the receiving tank and communicates with the receiving tank. A baffle is provided on the inner wall of the receiving tank, and a discharge port is connected to one side of the receiving tank. A valve is connected to the periphery of the discharge port. By adopting the above technical solution, the fixed connection between the discharge pipe and the receiving tank forms a closed continuous system, preventing the grease from contacting air and being oxidized or contaminated during the transfer process. It also ensures the effective establishment of a vacuum environment. The baffle can change the path of the grease flowing into the receiving tank, buffering and reducing the flow rate, which prevents grease splashing and promotes oil-gas separation.

[0007] Preferably, the upper surface of the storage tank is connected to a feed inlet, and the upper surface of the storage tank is also connected to a temperature sensor. The sensing end of the temperature sensor is located inside the storage tank and is electrically connected to an external controller. By adopting the above technical solution, the melting point and optimal processing temperature range of animal oils such as lard and tallow are crucial. The temperature sensor can monitor the oil temperature in real time and transmit the signal to the controller. The controller can then link with the heating system to achieve automatic and precise temperature control, preventing excessively high temperatures from causing oil decomposition and the production of harmful substances, or excessively low temperatures from causing solidification and poor fluidity.

[0008] Preferably, the cavity is filled with a heat-conducting medium through the liquid inlet, a heating seat is provided on the periphery of the storage tank, the heating wire is electrically connected to the heating seat, and the heating seat is electrically connected to an external controller. By adopting the above technical solution, the entire wall of the storage tank is heated by the heat-conducting medium. Compared with directly inserting an electric heating rod into the oil, this method has a larger heating area and more uniform temperature, effectively preventing local overheating. This is a typical indirect heating method. The heating wire does not directly contact the animal oil, completely eliminating the risk of the heating element surface temperature being too high and igniting the grease. It also avoids the grease from coking and carbonizing on the high-temperature element, resulting in extremely high safety performance.

[0009] Preferably, the storage tank has a transparent observation window on its surface, the vacuum pump is electrically connected to an external controller, the filter plate is shaped and sized to fit the slot and is inserted into the slot, and the filter plate is made of activated carbon.

[0010] Preferably, the limiting groove communicates with the movable groove, the positioning rod slides in conjunction with the sliding groove, and the shape and size of the limiting block are adapted to the limiting groove, wherein the limiting block has a trapezoidal structure. By adopting the above technical solution: the activated carbon filter plate is the core degassing and deodorizing element. Under vacuum conditions, small odor molecules in grease are more easily volatilized. When the gas extracted by the vacuum pump passes through the activated carbon filter plate, the odor molecules and trace volatile substances are strongly adsorbed by the activated carbon, thereby achieving the purpose of deodorization and purification.

[0011] Preferably, the left end of the spring is fixedly connected to one side of the limiting block, the right end of the spring is fixedly connected to one side of the movable groove, and the limiting block and the limiting groove are engaged.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model integrates a storage tank, receiving tank, filter box, and vacuum pump into a closed, continuous system. Utilizing vacuum negative pressure as power, it simultaneously completes the transportation, heating and insulation, degassing and deodorization, and filtration and purification of animal oil. The entire process is carried out in a sealed environment, effectively preventing the oil from oxidizing and deteriorating due to contact with air during transportation, eliminating secondary pollution, and significantly improving product quality and production efficiency.

[0013] 2. An indirect heating method using a jacketed cavity filled with a heat-conducting medium, combined with a temperature sensor and an external controller, enables real-time monitoring and precise automatic control of the oil temperature. This heating method not only ensures uniform heating, preventing localized overheating that could lead to grease decomposition or the production of harmful substances, but also completely isolates the heating element from the grease, fundamentally eliminating the safety hazard of grease igniting due to high temperatures on the heating element surface, thus greatly improving production safety.

[0014] 3. The filter box adopts a slot-type installation combined with a unique spring-limit block locking structure, making the installation and replacement of activated carbon filter plates extremely convenient. It automatically locks upon insertion, ensuring a seal and fixation; replacement is as simple as pulling the pull plate to unlock and remove the filter. This modular design significantly reduces equipment downtime and operational complexity, ensures continuous and stable degassing and filtration effects, and lowers long-term maintenance costs.

[0020] Please see Figure 1-5 This utility model provides a technical solution: An integrated vacuum conveying and degassing device for animal oil includes a storage tank 1 and a receiving tank 2. A filter box 21 is connected to one side of the receiving tank 2. Slots 210 are symmetrically formed on the surface of the filter box 21. Filter plates 211 are inserted into the slots 210. A limiting groove 212 is formed on one side of the filter plate 211. A movable groove 213 is formed on one side of the inner wall of the slot 210. A sliding groove 214 is formed on one side of the inner wall of the movable groove 213. A positioning rod 215 is inserted into the sliding groove 214. A limiting block 216 is provided at one end of the positioning rod 215. A spring 217 is sleeved on the periphery of the positioning rod 215. A vacuum pump 22 is connected to one side of the filter box 21. A cavity 10 is opened inside the storage tank 1. A heating wire 101 is sleeved on the inner wall of the cavity 10. An inlet 102 is connected to one side of the inner wall of the cavity 10. A discharge pipe 103 is connected to the bottom surface of the storage tank 1. A valve 104 is connected to the surface of the discharge pipe 103. One end of the discharge pipe 103 is fixedly connected to one side of the receiving tank 2 and communicates with the receiving tank 2. A baffle 20 is provided on the inner wall of the receiving tank 2. An outlet 201 is connected to one side of the receiving tank 2. A valve 202 is connected to the periphery of the outlet 201.

[0021] In this embodiment, a feed inlet 100 is connected to the upper surface of the storage tank 1, and a temperature sensor is connected to the upper surface of the storage tank 1. The sensing end of the temperature sensor is located inside the storage tank 1 and is electrically connected to an external controller. The cavity 10 is filled with a heat-conducting medium through the liquid inlet 102. A heating seat is provided on the periphery of the storage tank 1, and a heating wire 101 is electrically connected to the heating seat. The heating seat is electrically connected to an external controller. A transparent observation window is provided on the surface of the storage tank 1. The vacuum pump 22 is electrically connected to the external controller. The filter plate 2... The shape and size of the filter plate 211 are adapted to the slot 210 and are inserted into the slot 210. The filter plate 211 is made of activated carbon. The limiting groove 212 is connected to the movable groove 213. The positioning rod 215 is slidably engaged with the sliding groove 214. The shape and size of the limiting block 216 are adapted to the limiting groove 212. The limiting block 216 has a trapezoidal structure. The left end of the spring 217 is fixedly connected to one side of the limiting block 216, and the right end of the spring 217 is fixedly connected to one side of the movable groove 213. The limiting block 216 is engaged with the limiting groove 212.

[0022] The above scheme involves adding animal oil raw materials through the inlet 100 at the top of storage tank 1, activating the heating element connected to an external controller, and using current through the heating wire 101 to heat the heat-conducting medium (such as heat-conducting oil) inside the cavity 10. The heat-conducting medium evenly transfers heat to the animal oil in storage tank 1, melting it and maintaining it in a suitable fluid state for transport and processing. Once the animal oil in storage tank 1 reaches the predetermined temperature, all valves are closed, and the vacuum pump 22 connected to the external controller is activated. The vacuum pump 22 then begins to draw heat from the filter box 21 and the receiving... Air is drawn into tank 2, creating a negative pressure vacuum environment within the entire system. Since the pressure inside storage tank 1 is higher than that in receiving tank 2, the animal oil is "drawn" upwards by the pressure difference and flows through discharge pipe 103 into receiving tank 2. In this vacuum environment, dissolved or carried odor molecules, moisture, air, and other volatile substances in the animal oil are more easily released. Before entering vacuum pump 22, this extracted gas mixture must pass through filter box 21, which contains activated carbon filter plates 211. As the gas flows through filter plates 211, the large surface area of ​​the activated carbon strongly adsorbs odor molecules such as aldehydes, ketones, and other volatile impurities, thus achieving deodorization, degassing, and purification. The baffle 20 prevents the oil entering receiving tank 2 from directly impacting the tank bottom or walls, acting as a buffer and guide.

[0023] It should be noted that the animal oil raw material is added through the feed inlet 100 at the top of the storage tank 1. The heating element connected to the external controller is activated, and current flows through the heating wire 101 to heat the heat-conducting medium, such as heat-conducting oil, within the cavity 10. The heat-conducting medium evenly transfers heat to the animal oil in the storage tank 1, melting it and maintaining it in a suitable fluid state for transport and processing. When the animal oil in the storage tank 1 reaches the predetermined temperature, all valves are closed, and the vacuum pump 22 connected to the external controller is activated. The vacuum pump 22 begins to draw heat from the filter box 21 and the receiving... Air is drawn into tank 2, creating a negative pressure vacuum environment within the entire system.

The baffle 20 prevents the oil entering receiving tank 2 from directly impacting the tank bottom or wall, acting as a buffer and guide. When the filter plate 211 is inserted, the inclined surface of the trapezoidal limiting block 216 is compressed, causing the spring 217 to retract. When the limiting groove 212 on the filter plate 211 moves into place, the spring 217 instantly pushes the limiting block 216 into the groove, achieving automatic locking with a "click". When replacement is needed, simply pull the pull plate outward manually to make the limiting block 216 exit the limiting groove 212, and the filter plate 211 can be easily pulled out.
