[0027] In one embodiment, Figure 3As shown, the heating and stirring assembly includes a driving member 611, a stirring rod shaft 62 and a heating rod 63. The stirring rod shaft 62 is longitudinally rotatable and is arranged inside the heating box 61 and has multiple stirring rods 64 on the outer wall. The driving member 611 is arranged at the top of the heating box 61 and drives the stirring rod shaft 62 to rotate; the heating rod 63 is arranged inside the stirring rod shaft 62 and generates heat by energizing. In this embodiment, under the drive of the driving member 611, the heating rod 63 rotates and stirs the well washing fluid flowing into the heating box 61 through multiple stirring rods 64; the heating rod 63 generates heat when energized, and the heat heats the well washing fluid under the condition of heat conduction through the stirring rod shaft 62 and the stirring rod 64, and the well washing fluid can be evenly heated under stirring.

[0028] In one embodiment, Figure 3 As shown, the driving member 611 can drive the stirring rod shaft 62 to rotate alternately forward and reversely, and the heating stirring assembly also includes a spiral section 67, a spiral sleeve body 68 and two dials 69, the spiral section 67 is arranged on the outer wall of the stirring rod shaft 62 and the spiral sleeve body 68 is spirally sleeved on the spiral section 67, one end of the two dials 69 is hinged to the inner wall of the heating box body 61, and the side wall of the spiral sleeve body 68 is respectively hinged to the middle part of the two dials 69 through a push-pull connecting rod 681; in this embodiment, the driving member 611 can be a servo motor whose main shaft can rotate forward and reverse or other servo motor that can drive the stirring rod shaft 62. The mechanism of the rod shaft 62 rotating forward and reversely, the stirring rod shaft 62 rotates forward and reverse under the drive of the driving member 611, so that the stirring rod 64 rotates forward and reverse, so that the well washing fluid inside the heating box 61 is stirred alternately forward and reversely; under the spiral cooperation of the spiral section 67 and the screw sleeve body 68, the screw sleeve body 68 moves up and down along the axial direction of the stirring rod shaft 62, and the push of the push-pull connecting rod 681 makes the dial member 69 swing around the connection with the inner wall of the heating box 61, so that the well washing fluid inside the heating box 61 can be flipped up and down, so that the well washing fluid is more uniform during the heating process, thereby improving the heating efficiency.

[0029] In one embodiment, Figure 3 As shown, a sealing plate 66 is further provided on the inner wall of the heating box 61 at the drainage channel 65.
