When transporting the oily sludge, the oily sludge is squeezed to remove part of the oil and water in the oily sludge, and the oil is discharged and collected outside. The partition 215 is connected to the shell 211. A cleaning chamber 216 is formed between the right side of the partition 215 and the inner wall of the shell 211.

[0033] Continue to refer Figures 1 to 8 As shown, the water squeezing part 218 is connected to the shell 211, and is used to squeeze water from the drainage structure 214 removed from the cleaning chamber 216 to facilitate the recycling of the drainage structure 214. Two connecting pipes 219 are provided. The two connecting pipes 219 are arranged up and down and are both connected to the shell 211. The two connecting pipes 219 are both connected to the cleaning chamber 216. The upper connecting pipe 219 is a water pipe for conveying clean water into the cleaning chamber 216.

The blocking portion 2131 is connected to the shell 211, and the rotating portion 2132 is rotatably connected to the shell 211. The rotating portion 2132 is located on the inner side of the blocking portion 2131, and the outer peripheral surface of the rotating portion 2132 contacts the inner peripheral surface of the blocking portion 2131. The rotating portion 2132 is coaxially arranged with the blocking portion 2131, and the shell 211 is connected to the feeding channel 212. The right side of the blocking portion 2131 is provided with an opening 1 2134 and two openings 3 2136, and the opening 1 2134 is located between the two openings 3 2136. The bottom of the blocking portion 2131 is provided with an opening 2135, and four containing chambers 2133 are provided inside the rotating portion 2132 for containing oily sludge. The rotating portion 2132 can rotate, thereby driving the four containing chambers 2133 to contain the oily sludge in sequence. After part of the oil and water in the oily sludge is discharged through the drainage structure 214, the rotating portion 2132 drives the containing chamber 2133 to continue to rotate until the containing chamber 2133 is connected with the opening 2135, so that the oily sludge in the containing chamber 2133 falls from the opening 2135 to the bottom of the shell 211, so as to facilitate the subsequent use of superheated steam to treat the oily sludge.

[0035] Continue to refer Figures 1 to 8 As shown, the drainage structure 214 includes a rotating shaft 1 2141, a rotating shaft 2142, a guide rail 2143, a pushing part 2144, a filter cloth 2145, a supporting net 2146, a collecting part 2147 and a drainage pipe 2148. The rotating shaft 1 2141 and the rotating shaft 2142 are both rotatably connected to the inner side of the shell 211, and the rotating shaft 2142 is located in the cleaning chamber 216. The guide rail 2143 is connected to the shell 211, and the guide rail 2143 is coaxially arranged with the rotating part 2132. Four pushing parts 2144 are provided, and the four pushing parts 2144 are respectively inserted into the four containing chambers 2133. The four pushing parts 2144 are all slidably connected to the guide rail 2143. The filter cloth 2145 is transmission-connected to the rotating shaft 1 2141 and the rotating shaft 2142. The filter cloth 2145 is provided with two water squeezing parts 218, and the filter cloth 2145 is located between the two water squeezing parts 218. When the rotating shaft 1 2141, the rotating shaft 2142 and the filter cloth 2145 are transmitted, the cleaned filter cloth 2145 can be squeezed with water through the two water squeezing parts 218, and the filter cloth 2145 passes through the two openings 3 2136 in sequence. The supporting net 2146 is connected in the opening 1 2134 for supporting the filter cloth 2145. The collecting part 2147 is connected in the shell body 211, and the collecting part 2147 is communicated with the opening 1 2134. The drain pipe 2148 is connected to the front side of the shell body 211, and the drain pipe 2148 is communicated with the collecting part 2147.

[0036] When the rotating part 2132 rotates, the four pushing parts 2144 are driven to rotate along a circular trajectory through the four containing chambers 2133. When the containing chamber 2133 moves to the opening 1 2134, the pushing part 2144 in the containing chamber 2133 moves in a direction away from the center of the rotating part 2132 under the guidance of the guide rail 2143, so that the pushing part 2144 squeezes the oily sludge in the containing chamber 2133. At this time, under the obstruction of the filter cloth 2145, part of the oil and water can be filtered out. At the same time, the support net 2146 supports the compressed part of the filter cloth 2145. Part of the filtered oil and water enters the collecting part 2147 through the opening 1 2134 and is discharged outwardly from the drain pipe 2148, thereby reducing the time and energy consumption when steam is used to treat the oily sludge. The driving member 23 can drive the transmission between the rotating shaft 1 2141, the rotating shaft 2142 and the filter cloth 2145 to facilitate cleaning of the filter cloth 2145.

[0037] Continue to refer Figures 1 to 8 As shown, the cleaning structure 217 includes a cleaning roller 2171 and a gear 1 2172. The cleaning roller 2171 is rotatably connected in the cleaning chamber 216, and the cleaning roller 2171 is in contact with the filter cloth 2145. The gear 1 2172 is provided in two numbers, and the two gears 1 2172 are respectively connected to the cleaning roller 2171 and the rotating shaft 2142. When the rotating shaft 2142 rotates, the two gears 1 2172 are driven to engage and transmit, so that the cleaning roller 2171 rotates, and the part of the filter cloth 2145 located in the cleaning chamber 216 is cleaned, so as to facilitate the subsequent use of the filter cloth 2145.

[0038] Continue to refer Figures 1 to 8 As shown, the driving member 23 includes a protective shell 231, a driving source 232, a transmission structure 1 233, a rotating shaft 3 234, a transmission structure 2 235 and a gear 2 236. The protective shell 231 is connected to the shell 211, the rotating shaft 3 234 is rotatably connected to the front side of the shell 211, the transmission structure 1 233 and the transmission structure 2 235 are both composed of a transmission belt and two transmission wheels, the driving source 232 is a motor, the transmission structure 1 233 is connected between the output shaft of the driving source 232 and the rotating part 2132, the transmission structure 2 235 is connected between the rotating part 2132 and the rotating shaft 3 234, and the gear 2 236 is set to two, the two gears 236 are respectively connected to the rotating shaft 3 234 and the rotating shaft 1 2141, and the two gears 2 236 are meshed and connected.

[0039] The starting driving source 232 can drive the rotating part 2132 to rotate clockwise through the transmission structure 1 233. When the rotating part 2132 rotates clockwise, the transmission structure 2 235 drives the rotating shaft 3 234 to rotate clockwise, and drives the meshing transmission between the two gears 2 236 to make the rotating shaft 1 2141 rotate counterclockwise, thereby driving the filter cloth 2145, the rotating shaft 1 2141 and the rotating shaft 2 2142 to operate.

[0040] Working principle:

[0041] When the oil-water content in the oily sludge is high, the driving source 232 is started to drive the rotating part 2132 to rotate clockwise through the transmission structure 1 233, and the feeding mechanism 1 is started to sequentially convey the oily sludge to the four containing chambers 2133 of the rotating part 2132. When the rotating part 2132 rotates, the four pushing parts 2144 are driven to rotate along a circular trajectory through the four containing chambers 2133. When the containing chamber 2133 moves to the opening 1 2134, under the guidance of the guide rail 2143, the oily sludge is transported to the four containing chambers 2133 of the rotating part 2132. , so that the pushing part 2144 in the containing chamber 2133 moves in the direction away from the center of the rotating part 2132, so that the pushing part 2144 squeezes the oil-containing sludge in the containing chamber 2133. At this time, under the obstruction of the filter cloth 2145, part of the oil and water can be filtered out. At the same time, the support net 2146 supports the compressed part of the filter cloth 2145. Part of the filtered oil and water enters the collecting part 2147 through the opening 2134 and is discharged outwardly through the drain pipe 2148.

[0042] When the rotating part 2132 rotates clockwise, the transmission structure 235 drives the rotating shaft 3 234 to rotate clockwise, and drives the two gears 236 to mesh and transmit, so that the rotating shaft 1 2141 rotates counterclockwise, thereby driving the filter cloth 2145, the rotating shaft 1 2141 and the rotating shaft 2 2142 to operate.

[0043] When the second rotating shaft 2142 rotates, it drives the two first gears 2172 to mesh and transmit, so that the cleaning roller 2171 rotates and cleans the filter cloth 2145 located in the cleaning chamber 216.

[0044] After the containing chamber 2133 containing the oily sludge processed by the drainage structure 214 is connected to the second opening 2135 , the oily sludge in the containing chamber 2133 falls from the second opening 2135 to the bottom of the shell 211 .

[0045] The external superheated steam injection device is started, and the oily sludge after part of the oil and water are discharged is transported to the treatment mechanism 3 through steam energy, and the oily sludge is treated by superheated steam in the treatment mechanism 3, so that the water and oil are separated from the sludge to form water vapor and oil vapor, and the sludge after the water and oil are removed is discharged by the slag discharge mechanism 4, and the water vapor and oil vapor are transported to the external condensation equipment after being treated by the separation mechanism 1 5 and the separation mechanism 2 6, so that the water vapor and the oil vapor are condensed and gathered together.
