Since the plurality of branch pipes 114 are equidistantly arranged in the water guide ring 113, the water sprayed from the branch pipes 114 can be injected into the sludge from multiple directions, so that the water can fully contact with the sludge, which is beneficial to the subsequent oil-water separation effect.

[0043] As shown in the drawings, Figure 11As shown, as further schemes of the present application, the driving assembly 19 comprises a fixing plate 191 fixed on the top of the treatment tank 1, a motor 192 fixed in the fixing plate 191, a driving gear 193 fixedly connected on the output shaft of the motor 192, the driving gear 193 being in meshing connection with the driven gear 603 to drive the connecting shaft 602 to rotate.

The sludge filtering float head 203 is located at the uppermost layer under the influence of buoyancy, the extraction pipe 201 is connected to an external extraction device, and the upper layer of floating oil in the treatment tank 1 is first extracted and recovered. After the extraction of the floating oil is completed, the sludge filtering float head 203 descends according to the height of the mixture in the treatment tank 1 and contacts the middle layer of water, the water can be extracted, and the sludge is discharged from the discharge valve 3, thereby facilitating the separate recovery and treatment of oil and water.

[0046] Working principle of the present application:

[0047] In the recycling of high oil industrial sludge, the sludge is extruded into the feeding cylinder 5 through the feeding hopper 10. The motor 192 is controlled to work to drive the driving gear 193 to rotate, which drives the connecting shaft 602 and the second grinding disc 17 to rotate through the driven gear 603. The connecting shaft 602 drives the auger 601 to rotate inside the feeding cylinder 5. The auger 601 can transport the sludge to the left during rotation, and the spiral blades on the auger 601 can preliminarily disperse the caked sludge. The electric heating wire 8 is controlled to work to transmit heat to the feeding cylinder 5 through the cavity 7, and the heat in the feeding cylinder 5 is transmitted to the sludge, achieving the purpose of preheating the sludge and emulsifying the solidified oil stains in the sludge.

[0048] The water inlet end of the water pump 111 is connected to a water source, and the water pump 111 can guide water into the water guide ring 113 through the connecting pipe 112. The water guide ring 113 can inject water into the feeding cylinder 5 from the multiple branch pipes 114. The branch pipes 114 are equidistantly arranged in the water guide ring 113, so that the water sprayed from the branch pipes 114 can be injected into the sludge from multiple directions, so that the water can fully contact with the sludge, which is beneficial to the subsequent oil-water separation effect.

[0049] As the auger 601 continuously rotates, the sludge with high water content can be discharged from the feeding cylinder 5, so that the sludge can be transferred to the feeding hole 16 in the first grinding disc 15 and contact with the second grinding disc 17. The opposite surfaces of the first grinding disc 15 and the second grinding disc 17 are provided with abrasive textures in opposite directions, and the abrasive texture on one side of the first grinding disc 15 is communicated with the feeding hole. During the rotation of the second grinding disc 17, the sludge can be guided into the space between the first grinding disc 15 and the second grinding disc 17. The first grinding disc 15 is fixed with the feeding cylinder 5 and is in a static state, so that the two abrasive textures in opposite directions in the first grinding disc 15 and the second grinding disc 17 can grind the sludge deeply to reduce the particle size of the particles in the sludge. The water sprayed by the branch pipes 114 continuously into the sludge can further improve the grinding effect of the sludge by water grinding, increase the contact area between the particles in the sludge and water, and effectively remove the oil layer adsorbed in the sludge.

[0050] In the process of water grinding of the sludge by the first grinding disc 15 and the second grinding disc 17, the ground sludge falls into the treatment box 1 from the lower hopper 14, and the protective cover 13 above the fixed frame 12 is transparent, so that the grinding state can be observed. When there are hard particles in the sludge that are difficult to grind, the hard particles will extrude the second grinding disc 17 when the particles pass through the feeding hole 16 in the first grinding disc 15 and enter between the first grinding disc 15 and the second grinding disc 17, so that the second grinding disc 17 drives the sleeve 18 to slide in the sliding groove 605 outside the connecting shaft 602, so that the second grinding disc 17 can move away from the first grinding disc 15, and the hard particles can be guided out by the continuous rotation of the second grinding disc 17; the protrusions on the inner wall of the sleeve 18 slide in the sliding groove 605 to limit the second grinding disc 17, so that the second grinding disc 17 can move horizontally outside the connecting shaft 602 while the connecting shaft 602 drives the sleeve 18 and the second grinding disc 17 to rotate. Secondly, the spring 606 supports the sleeve 18, so that the sleeve 18 drives the second grinding disc 17 to move close to the first grinding disc 15 and extrude the sludge, thereby improving the grinding effect of the first grinding disc 15 and the second grinding disc 17 on the sludge, and thus the distance between the first grinding disc 15 and the second grinding disc 17 can be automatically adjusted according to the particle size of the sludge to perform the grinding work.

[0051] After the ground sludge enters the treatment box 1, the motor 192 works to drive the rotating shaft 194 to rotate through the driving gear 193, and the rotating shaft 194 drives the plurality of stirring blades 195 to fully mix the sludge and water, thereby improving the separation effect of water, oil and mud. After the mixing is completed, the mixture is allowed to stand and settle, and the density difference between oil, water and mud is utilized to realize layering under the action of gravity, so that the oil is located in the uppermost layer, the water is located in the middle layer, and the mud is located in the bottom layer. The bottom of the extraction pipe 201 is connected to the mud filter float head 203, and the mud filter float head 203 is located in the uppermost layer under the influence of buoyancy.

[0052] The extraction pipe 201 is connected to the external extraction device, and first, the floating oil in the upper layer of the treatment box 1 is extracted and recovered. After the extraction of the floating oil is completed, the mud filter float head 203 descends according to the height of the mixture in the treatment box 1 and contacts the water in the middle layer. The extraction pipe 201 slides in the pipe sleeve 202 to reduce the moving friction. After the extraction and recovery of the water are completed, the mud filter float head 203 contacts the sludge in the bottom layer of the treatment box 1. To prevent the sediment from blocking the extraction pipe 201, the filter holes on the outer wall of the mud filter float head 203 can block the sediment. Secondly, the extraction pipe 201 is pulled out, and the extraction pipe 201 together with the pipe sleeve 202 is taken out from the top of the treatment box 1.

[0053] When the precipitate is recovered, the heating base 2 is controlled to work to generate heat which can be transferred to the precipitate, and the stirring blade 195 is matched to stir the precipitate, so as to improve the heating uniformity of the precipitate. The water vapor generated by heating is discharged from the exhaust valve pipe 21, so as to accelerate the evaporation speed of the water vapor in the treatment box 1. After the precipitate in the treatment box 1 is dried, the heating base 2 stops working. The discharge valve 3 at the bottom of the treatment box 1 is opened, and the rotating shaft 194 can drive the spiral rod 196 at the bottom to rotate during the rotation process. Since the spiral rod 196 is located directly above the discharge valve 3, the spiral rod 196 can convey the precipitate downward and discharge the precipitate from the discharge valve 3 during the rotation process, so as to prevent the dried precipitate from causing the discharge valve 3 to be blocked and difficult to discharge, that is, the recovery work of the sludge is completed.
