[0037] The stirring device comprises a motor 5, a rotating shaft 6, a connecting plate 7, an electric telescopic rod 8, a stirring rod 9, a semicircular plate 13 and an inclined block 14.

The bottom of the feeding pipe 3 is closed by the mutual cooperation of the two semicircular plates 13, so as to prevent the oil to be treated from entering and breaking the originally set proportion of the solvent and the oil, causing the concentration of the leaching liquid to be abnormal, affecting the subsequent oil separation and solvent recovery processes, and at the same time, the entry of the oil will change the total volume and heat capacity of the materials, thereby affecting the control of the leaching temperature, prolonging the leaching time, and even possibly causing incomplete leaching.

The sliding rod 10 is slidingly installed on the inner wall of the reaction tank 1, the bottom ring 11 is fixedly installed on the bottom of the sliding rod 10, and the sliding rail 12 is fixedly installed in the reaction tank 1.

[0039] A production process for a biological fat leaching device, using the above-mentioned fat leaching device for biological oil production, comprising the following steps:

[0040] Step 1: First, before starting to process the oil, the staff will check the working status of the oil extractor. After the staff completes the inspection and confirms that it is correct, the staff will pass the oil into the reaction tank 1 through the feed pipe 3. After the introduction is completed, a certain amount of solvent will be passed into the reaction tank 1;

[0041] Step 2: After the oil is introduced, the staff starts the electric telescopic rod 8, so that the electric telescopic rod 8 drives the stirring rod 9 to start moving downward, and stops after the stirring rod 9 moves into the oil. Then the motor 5 is started, so that the motor 5 drives the rotating shaft 6 to start rotating. The rotating shaft 6 drives the connecting plate 7 to start rotating. The connecting plate 7 drives the electric telescopic rod 8 to start rotating. The electric telescopic rod 8 drives the stirring rod 9 to start rotating. The stirring rod 9 rotates to make the oil particles roll continuously in the solvent.

[0042] Step three: When the electric telescopic rod 8 drives the stirring rod 9 to start moving downward, it no longer pushes the bottom ring 11. Then, the bottom ring 11 starts to move downward under the action of gravity. The movement of the bottom ring 11 drives the slide bar 10 to start moving downward. The downward movement of the slide bar 10 no longer pushes the inclined plane block 14 to start moving. Then, the inclined plane block 14 starts to move toward the direction of the feed pipe 3 and resets under the action of spring 1. The movement of the inclined plane block 14 drives the semicircular plate 13 to start moving and reset on the top of the slide rail 12. The bottom of the feed pipe 3 is closed with the cooperation of the two semicircular plates 13.

[0043] When this embodiment works: first, before starting to process the oil, the staff will check the working status of the oil extractor. After the staff has checked and confirmed that there is no problem, the staff will pass the oil into the reaction tank 1 through the feed pipe 3. After the introduction is completed, a certain amount of solvent will be passed into the reaction tank 1. Then, after waiting for the reaction to be completed, the oil that has completed the reaction will be discharged through the discharge pipe 4. After the oil is introduced, the staff will start the electric telescopic rod 8, so that the electric telescopic rod 8 drives the stirring rod 9 to start moving downward, and the stirring rod 9 stops after moving into the oil. Then, the motor 5 is started, so that the motor 5 drives the rotating shaft 6 to start rotating, and the rotating shaft 6 rotates to drive the connecting plate 7 to start rotating, and the connecting plate 7 rotates to drive the electric telescopic rod 8 to start rotating, and the electric telescopic rod 8 rotates to drive the stirring rod 9 to start rotating. The stirring rod 9 rotates to make the oil particles roll continuously in the solvent, and the oil particles that are piled up or agglomerated with each other are dispersed, so that more oil surfaces can directly contact with the solvent, which greatly increases the contact area between the oil and the solvent. The fat can be dissolved from the oil into the solvent more quickly, and the fat in the oil can also diffuse into the main body of the solvent more quickly, thereby accelerating the mass transfer rate and improving the leaching efficiency. When the electric telescopic rod 8 drives the stirring rod 9 to start moving downward, it no longer pushes the bottom ring 11. Then the bottom ring 11 starts to move downward under the action of gravity, and the movement of the bottom ring 11 drives the sliding rod 10 to start moving downward. The downward movement of the sliding rod 10 no longer pushes the inclined plane block 14 to start moving, and then the inclined plane block 14 starts to move toward the direction of the feed pipe 3 under the action of spring 1 to reset. The movement of the inclined plane block 14 drives the semicircular plate 13 to start moving and reset on the top of the slide rail 12. The bottom of the feed pipe 3 is closed with the cooperation of the two semicircular plates 13 to prevent the entry of the oil to be processed from breaking the originally set ratio of solvent to oil, resulting in abnormal concentration of the leachate, affecting subsequent oil separation and solvent recovery processes, and at the same time, the entry of oil will change the total volume and heat capacity of the material, thereby affecting the control of the leaching temperature, prolonging the leaching time, and even causing incomplete leaching.

[0044] See also Figures 1-8 On the basis of the above embodiment, in another embodiment of the present invention, a ventilation device for ventilation during the reaction and a restriction device for filtering the gas generated in the reaction are provided on the top of the reaction tank 1.

By moving the closing plate 155 to open the channel between the ventilation pipe 152 and the reaction tank 1, the vapor volatilized by the solvent can be discharged from the extractor in time to prevent it from accumulating in the equipment, reducing safety hazards such as explosion, and also promoting the mass transfer process between the solvent and the oil in a direction that is conducive to oil leaching, thereby improving the leaching efficiency.

[0046] The ventilation device also includes a second motor 157, a rotating rod 158 and fan blades 159.

[0047] The contact surfaces of the push rod 151 and the bottom rod 156 are both set as inclined surfaces, and the closing plate 155 is in contact with the ventilation pipe 152. The inclined surfaces ensure that the push rod 151 can smoothly push the bottom rod 156 when moving, and the contact ensures that the closing plate 155 can control the opening and closing of the ventilation pipe 152 channel.

[0048] The limiting device includes a top pipe 161, an absorption box 162, a handle 163 and a limiting rod 164.

The limiting rod 164 moves to contact the limiting groove on the absorption box 162 and limit the absorption box 162, thereby preventing the absorption box 162 from being displaced due to vibration when the extractor is working, affecting the sealing of the ventilation system, ensuring the stable operation of the ventilation system, and thus ensuring that the solvent vapor in the extractor can be effectively discharged.

[0049] The limiting device further comprises a sliding plate 165, an inclined block two 166 and a fixed rod 167. The sliding plate 165 is slidingly installed inside the top pipe 161, the inclined block two 166 is fixedly installed at the bottom of the sliding plate 165, and the fixed rod 167 is fixedly installed at the top of the absorption box 162. The top of the top pipe 161 is closed by the cooperation of the two sliding plates 165, so as to avoid the entry of dust, sundries, insects and other foreign matters into the inside of the extractor, and meanwhile, the relatively stable temperature and humidity environment in the inside of the extractor can be maintained, which is helpful to prolong the service life of the equipment.

[0050] The top of the absorption box 162 is provided with a limiting groove, one side of the fixed rod 167 and the inclined block two 166 in contact with each other is provided with an inclined surface, and the sliding plate 165 and the top pipe 161 are provided with a spring two. The limiting groove ensures that the absorption box 162 can be limited, the inclined surface ensures that the fixed rod 167 can smoothly push the inclined block two 166 when moving, and the spring ensures that the sliding plate 165 can be automatically reset.

[0051] When the half-round plate 13 starts to move and reset on the top of the sliding rail 12, the push rod 151 starts to move, the push rod 151 moves to contact and push the bottom rod 156 to start to move downward, the bottom rod 156 moves to drive the closing plate 155 to start to move downward, the closing plate 155 moves to open the passage between the ventilation pipe 152 and the reaction kettle 1, the steam generated by the solvent volatilization can be discharged from the extractor in time, so as to prevent the accumulation of the steam in the equipment, reduce the safety hidden danger such as explosion, and promote the mass transfer process between the solvent and the oil material to the direction beneficial to the oil extraction, thereby improving the extraction efficiency. After the closing plate 155 moves to open the passage between the ventilation pipe 152 and the reaction kettle 1, the motor two 157 is manually opened by the staff when needed, the motor two 157 drives the rotating rod 158 to start to rotate, the rotating rod 158 rotates to drive the fan blade 159 to start to rotate, the fan blade 159 rotates to introduce the external cold air or discharge the hot air, so as to realize heat exchange, thereby adjusting the temperature in the extractor, and preventing the influence on the oil quality or the increase of solvent loss due to the too high temperature.

[0052] When the closing plate 155 starts to move downward to open the passage between the ventilation pipe 152 and the reaction tank 1, the limiting rod 164 starts to move downward. The limiting rod 164 moves to contact the limiting groove on the absorption box 162 and restricts the absorption box 162 to prevent the absorption box 162 from being displaced due to vibration when the extractor is working, affecting the sealing of the ventilation system, ensuring the stable operation of the ventilation system, and thus ensuring that the solvent vapor in the extractor can be effectively discharged. After the work is completed, the staff takes out the absorption box 162 through the handle 163 When replacing or cleaning, the absorption box 162 starts to move driven by the handle 163, and the movement of the absorption box 162 drives the fixed rod 167 to start moving. The fixed rod 167 moves and no longer contacts the inclined block 2 166. Then the slide 165 starts to move and reset under the action of spring 2. With the cooperation of the two slides 165, the top of the top pipe 161 is sealed to prevent external dust, debris, insects and other foreign matter from entering the extractor. At the same time, it can maintain a relatively stable temperature and humidity environment inside the extractor, which helps to extend the service life of the equipment.
