[0024] Please refer toFigures 1-5 , the present utility model provides the following technical solutions:

[0025] Specifically, it refers to an oil residue machine discharge heating device, including an oil residue separator 1 and a discharge pipe 2 provided on the lower side of the oil residue separator 1. The discharge pipe 2 is installed at the bottom of the discharge port of the oil residue separator 1 and is internally connected to the inside of the discharge port. The oil residue separator 1 is a known prior art and will not be elaborated here. In this way, the oil separated by the oil residue separator 1 falls into the discharge pipe 2 through the discharge port.

[0026] The discharge pipe 2 includes an inner pipe 202 and a heat insulation layer 201 sleeved on the outer surface of the inner pipe 202. At the same time, the inner pipe 202 is made of a metal material with good thermal conductivity, such as copper and other metal materials. A plurality of built-in heating rings 203 are embedded in the inner pipe 202. During use, the built-in heating rings 203 are energized, and the heat generated by the built-in heating rings 203 can be conducted to the inner side of the inner pipe 202. The setting of the heat insulation layer 201 reduces the heat loss, so the oil falling into the discharge pipe 2 can be heated.

[0027] A rotating shaft 3 is rotatably connected between the front and rear inner walls of the discharge pipe 2. A screw blade 4 is sleeved on the outer surface of the rotating shaft 3. The outer surface of the screw blade 4 is in contact with and abuts against the inner wall of the discharge pipe 2. A servo motor 5 for controlling the rotation of the rotating shaft 3 is provided on the rear side surface of the discharge pipe 2. At the same time, the servo motor 5 does not have a self-locking function. A discharge pipe 7 communicating with its inside is provided on the lower surface of the discharge pipe 2 away from the oil residue separator 1. A storage tank 6 communicating with its inside is provided on the upper surface of the discharge pipe 2. A large amount of coagulant (such as starch) is stored in the storage tank 6. An electromagnetic valve for controlling the dropping of the coagulant is provided on the storage tank 6. During use, the built-in heating rings 203 are first turned on to preheat the inside of the discharge pipe 2. The servo motor 5 is started and drives the rotating shaft 3 to rotate, and the screw blade 4 rotates synchronously with the rotating shaft 3. In this way, the oil falling into the discharge pipe 2 is conveyed to the side of the discharge pipe 7 under the push of the screw blade 4. In this way, the oil is heated by the built-in heating rings 203 during transportation in the discharge pipe 2. At the same time, the electromagnetic valve on the storage tank 6 is opened, so that the coagulant in the storage tank 6 falls into the discharge pipe 2 and is mixed with the heated oil in the discharge pipe 2. The coagulant adsorbs the tiny impurities in the oil and removes the peculiar smell. By adopting the above method, the oil separated by the oil residue separator 1 can be continuously heated and purified, and it is not necessary to stop the oil residue separator 1 to heat and purify the separated oil, which improves the speed and efficiency of oil treatment.

[0028] The outer surface of the discharge pipe 7 is provided with a drawer 8 that slides through one side into the discharge pipe 7. The outer surface of the drawer 8 on one side inside the discharge pipe 7 is attached to the inner wall of the discharge pipe 7. The side of the drawer 8 inside the discharge pipe 7 is in a square shape. A filter screen 9 for filtering the purified oil is arranged inside the drawer 8. Therefore, when the coagulant absorbs the impurities in the oil, it will be synchronously conveyed to the discharge pipe 7 along with the auger blade 4 and fall into the drawer 8. At the same time, the purified oil drops out through the mesh holes of the filter screen 9, while the coagulant and the absorbed impurities are blocked on the filter screen 9, making the color of the oil discharged from the discharge pipe 7 clear.

[0029] An anti-blocking mechanism 10 for preventing the filter screen 9 from being blocked is arranged inside the drawer 8. The anti-blocking mechanism 10 includes two mounting rods 101. The front and rear ends of the two mounting rods 101 are respectively arranged on the front and rear inner walls of the drawer 8 and are arranged parallel to each other left and right. A plurality of connecting plates 102 are slidably sleeved on the two mounting rods 101. A synchronous plate 103 is arranged between two adjacent connecting plates 102. Therefore, only one connecting plate 102 needs to slide on the mounting rod 101, and all the connecting plates 102 move synchronously under the action of the synchronous plate 103. A cleaning brush 104 that contacts the upper surface of the filter screen 9 is arranged on the lower surface of the connecting plate 102. During use, by controlling the connecting plate 102 to slide back and forth on the mounting rod 101, the cleaning brush 104 can be driven to brush back and forth on the filter screen 9. In this way, the impurities attached to the filter screen 9 are no longer blocked by the filter screen 9 due to the brushing of the cleaning brush 104, further ensuring the filtering effect of the filter screen 9 on the impurities and improving the filtering efficiency of the oil.

[0030] A first mounting plate 105 is arranged on the front inner wall of the drawer 8. A first push rod 106 is slidably sleeved on the first mounting plate 105. A movable plate 107 is arranged at the lower end of the first push rod 106. A first tension spring 109 that is movably sleeved on the outer surface of the first push rod 106 is arranged between the upper surface of the movable plate 107 and the first mounting plate 105. When the first tension spring 109 is not affected by the pulling force, the first tension spring 109 will form a pulling force on the movable plate 107, making the initial position of the movable plate 107 be on the side close to the first mounting plate 105. Therefore, the upper surface of the first push rod 106 is flush with the upper surface of the drawer 8, so that when the drawer 8 is pulled out or pushed into the discharge pipe 7, the first push rod 106 will not cause obstruction. A rotating plate 108 is hinged between the lower surface of the movable plate 107 and the connecting plate 102.

[0031] A pushing mechanism 11 for controlling the downward movement of the first push rod 106 is arranged on the outer surface of the rotating shaft 3. The pushing mechanism 11 includes an arc-shaped convex block 1101, and the arc-shaped convex block 1101 is arranged on the outer surface of the rotating shaft 3 close to the discharge pipe 7. A second mounting plate 1103 is arranged on the front inner wall of the discharge pipe 7. A second push rod 1102 is slidably sleeved on the second mounting plate 1103. The upper end of the second push rod 1102 contacts the arc surface of the arc-shaped convex block 1101. A push plate 1104 is arranged at the lower end of the second push rod 1102. The push plate 1104 is located directly above the first push rod 106 and contacts the first push rod 106 when moving downward. A second tension spring 1105 which is movably sleeved on the outer surface of the second push rod 1102 is arranged between the upper surface of the push plate 1104 and the second mounting plate 1103. In this way, when the rotating shaft 3 rotates, the arc-shaped convex block 1101 rotates synchronously with the rotating shaft 3. When the arc-shaped convex block 1101 contacts the upper end of the second push rod 1102, the arc-shaped convex block 1101 will form a downward thrust on the second push rod 1102, so that the second push rod 1102 pushes the push plate 1104 to move downward and contacts the upper end of the first push rod 106. In this way, the first push rod 106 moves downward synchronously with the second push rod 1102. At the same time, the first tension spring 109 and the second tension spring 1105 are stretched synchronously, so that the rotating plate 108 will form a thrust on the connecting plate 102, causing the connecting plate 102 to displace backward. When the arc-shaped convex block 1101 does not contact the second push rod 1102, the first push rod 106 and the second push rod 1102 respectively return to the initial position under the pulling of the first tension spring 109 and the second tension spring 1105. At this time, the rotating plate 108 pulls the connecting plate 102 to displace forward. With the above structure, when the rotating shaft 3 rotates, the anti-blocking mechanism 10 can be automatically controlled to brush the surface of the filter screen 9, without additional electric components, making the mechanism have better environmental protection value and significance.

[0032] When the servo motor 5 stops and the arc-shaped convex block 1101 contacts the second push rod 1102, since the servo motor 5 is not provided with a self-locking structure, after the servo motor 5 is powered off, the rotating shaft 3 can rotate. In this way, under the pushing of the first tension spring 109 and the second tension spring 1105, the second push rod 1102 can push the arc-shaped convex block 1101 to drive the rotating shaft 3 to rotate. Therefore, the lower end of the second push rod 1102 will not extend into the drawer 8 and affect the extraction of the drawer 8.

[0033] The working principle of the discharge heating device of the oil residue machine provided by the utility model is as follows: during use, the built-in heating ring 203 is turned on first to preheat the inside of the discharge pipe 2. The servo motor 5 starts and drives the rotating shaft 3 to rotate, and the auger blade 4 rotates synchronously with the rotating shaft 3. In this way, the oil falling into the discharge pipe 2 is conveyed to one side of the discharge pipe 7 under the push of the auger blade 4. In this way, the oil is heated by the built-in heating ring 203 when being conveyed in the discharge pipe 2. At the same time, the electromagnetic valve on the storage tank 6 is opened, so that the coagulant in the storage tank 6 falls into the discharge pipe 2 and is mixed with the heated oil in the discharge pipe 2. The coagulant adsorbs the tiny impurities in the oil and removes the peculiar smell.
