[0002] The experimental background technology for the preparation of heavy oil viscosity reducers mainly involves the extraction and transportation of heavy oil. Due to its high viscosity, heavy oil is difficult to flow, which limits its extraction efficiency and economic viability.

The amount and type of viscosity reducer, as well as the heating temperature, need to be tested to obtain the results.

[0029] A groove is provided on the surface of the transmission rod 105, and a through hole is vertically provided inside the transmission rod 105. A pressure rod 114 is vertically provided in the through hole. A spring 109 is fixedly connected to the bottom of the pressure rod 114. The two ends of the spring 109 are against the pressure rod 114 and the bottom of the groove. A partition 107 is vertically provided on the bottom surface of the groove opening, and a pressure block 108 is horizontally provided on the top of the groove.

[0030] Among them, the first gear 15 and the second gear 16 are meshed and connected, the second gear 16 and the third gear 17 are meshed and connected, the first gear 15 and the internal gear 6 are meshed and connected, and the motor 7 is fixedly connected to the top of the fixed cover 2, the output end of the motor 7 is fixedly connected to the first gear 15, and the second gear 16 is rotatably connected to the fixed cover 2.

[0031] A plurality of blades 103 are fixedly connected to the inner wall of the third gear 17 . One end of the blade 103 away from the third gear 17 is fixedly connected to a rotating ring 116 . The rotating ring 116 is rotatably connected to the transmission rod 105 .

[0032] Wherein, a funnel 13 is fixedly connected to the bottom of the shell 1.

[0033] Among them, the bottom end of the feeding tube 3 115 is fixedly connected to a conduit 5, and the conduit 5 passes through the funnel 13.

[0034] The bottom of the funnel 13 is fixedly connected to a base 14 .

[0037] like Figure 1-7As shown, in this embodiment, the device is connected to a power supply and a controller, a certain proportion of thick oil and viscosity reducer are added to the hopper 3, and the motor 7 fixedly connected to the top of the fixed cover 2 is started. The motor 7 drives the first gear 15 fixedly connected to the bottom of the fixed cover 2 to rotate. Since the first gear 15 and the second gear 16 are engaged, the first gear 15 drives the second gear 16 to rotate. Since the second gear 16 is engaged with the third gear 17, the second gear 16 drives the third gear 17 to rotate. The third gear 17 drives the paddle 103 fixedly connected thereto to rotate, and the paddle 103 drives the transmission rod 105 to rotate. The connected rotating ring 116 rotates, and the blade 103 extracts the heavy oil and viscosity reducer in the hopper 3 fixedly connected to the top of the feeding pipe 101 through the feeding pipe 1 101 connected to the top of the third gear 17. The feeding pipe 101 is fixedly connected to the fixed cover 2, and the feeding pipe 101 passes through the fixed cover 2. The heavy oil and viscosity reducer pass through the inner liner cover 11 and then flow into the feeding pipe 2 106 which is rotatably connected to the bottom of the inner liner cover 11 through the fixed rod 104. The heavy oil and viscosity reducer flow downward in the feeding pipe 2 106 to trigger the pressure block 108, and the pressure block 108 drives the pressure rod 1 fixedly connected to it. 14, the pressure rod 114 moves up and down in the through hole vertically provided in the transmission rod 105 and in the transmission tube 113 at the top of the transmission rod 105, and the top end of the pressure rod 114 floats up and down in the transparent tube 12. The current viscosity of the heavy oil can be intuitively seen through the transparent tube 12. When the heavy oil falls in the delivery pipe 106, the pressure rod 114 compresses the spring 109 downward. When the heavy oil and the viscosity reducer continue to fall, they continue to fall through the fixed plate 111 fixedly connected to the transmission rod 105 and the stop ring 110 fixedly connected to the fixed plate 111, and flow to the stop ring fixedly connected to the transmission rod 105. The oil flows on the flow block 112 to the bottom of the outer shell 1 and the bottom end of the propeller 8. The first gear 15 rotates while driving the internal gear 6 fixedly connected to the inner liner cover 11 to rotate. The inner liner cover 11 drives the fixedly connected propeller 8 to rotate through the fixed rod 104 and the feed pipe 2 106. The propeller 8 stirs the heavy oil and the viscosity reducer. During the stirring process, the propeller 8 transports the heavy oil and the viscosity reducer at the bottom of the outer shell 1 to the top of the propeller 8, and then passes through the gap between the fixed rods 104 fixedly connected between the inner liner cover 11 and the feed pipe 2 106, and flows into the feed pipe 2 106 again.

[0038] The above steps are repeated multiple times to mix the heavy oil and the viscosity reducer. The heavy oil and the viscosity reducer are heated by the heating tube 9 fixedly connected to the surface of the propeller 8. The position of the top of the pressure rod 114 is observed through the transparent tube 12. Combined with the scale line of the transparent tube 12, the current viscosity of the mixture of the heavy oil and the viscosity reducer is quickly determined. Depending on the situation, the viscosity reducer is added in small amounts multiple times until the viscosity of the mixture of the heavy oil and the viscosity reducer is reduced to the target value. When the viscosity of the mixture of the heavy oil and the viscosity reducer decreases, the spring 109 rebounds, and the spring 109 pushes the pressure rod 114 upward, and the top of the pressure rod 114 rises to the position of the transparent tube 12.

[0039] During the experiment, by pushing or pulling the pull rod 4, the pull rod 4 rotates around the place where the hopper 3 and the pull rod 4 are rotatably connected, and the pull rod 4 drives the connecting rod 102 rotatably connected to it to move, and the connecting rod 102 drives the transmission rod 105 rotatably connected to it to move up and down, and the transmission rod 105 drives the stop ring 110 to move downward through the fixed plate 111, and the transmission rod 105 drives the stop block 112 fixedly connected to it to move up and down. When the stop block 112 moves to the bottom end of the feed pipe three 115 fixedly connected to the outer shell 1, the conduit 5 and the feed pipe three 115 are between the stop ring 110 and the stop block 112, and the stop ring 110 blocks the gap between the feed pipe three 115 and the feed pipe two 106. The mixture of heavy oil and viscosity reducer in the feed pipe two 106 flows to the top of the stop block 112, then flows into the conduit 5, and then flows out through the conduit 5, and sampling can be carried out.

[0040] When it is necessary to quickly discharge the mixture of heavy oil and viscosity reducer in the inner liner wall 10, the stop block 112 is moved to the outside of the feed pipe three 115, and the stop ring 110 is moved into the feed pipe three 115. The mixture of heavy oil and viscosity reducer flows out through the bottom of the feed pipe three 115 until it flows into the funnel 13, is collected by the funnel 13, and then flows out from the bottom of the funnel 13.
