The temperature control part comprises a heating barrel 2, and a connecting pipe 3 is fixedly connected to the middle part of the lower surface of the heating barrel 2, and the connecting pipe 3 extends on the tube body outside the heating barrel 2 and is provided with an external thread for connecting a steam pipe. An inlet pipe 4 is installed in the middle part of the upper surface of the heating barrel 2, and the lower end of the inlet pipe 4 is fixedly connected and communicated with the heating barrel 2, and the upper end of the inlet pipe 4 is connected and communicated with the heat preservation part, and a condensation part is installed on the lower side of the heat preservation part, and the condensation part comprises a guide pipe 5 and a condensation box 6, the lower end of the guide pipe 5 is connected and communicated with the heat preservation part, and the upper end of the guide pipe 5 is fixedly connected to the condensation box 6 and extends inside it, wherein an exhaust hole is opened on the upper surface of the condensation box 6.
[0027] The working principle and beneficial effects of the above technical solution are as follows: when the temperature is low, the threaded part of the connecting pipe 3 is first connected to the external steam pipe, and the high-temperature steam is transported into the insulation part through the inlet pipe 4, and heat exchange is carried out with the tube body of the sampler main body 1 and the internal oil slurry, so as to increase the temperature of the oil slurry in the tube body to above the solidification point, so that the staff can smoothly take samples in cold weather. The steam passing through the insulation part continues to rise and is transported to the condensation box 6 through the guide pipe 5. Part of the steam is discharged from the exhaust hole 7, and the rest is condensed into liquid and falls back into the condensation box 6. The narrower pipe mouth at the upper end of the guide pipe 5 can prevent the condensed water from falling directly, thereby ensuring the heating efficiency.
[0028] In one embodiment, the heat preservation part includes a heat preservation tube 7 and a pair of collars 8 , and each collar 8 is rotatably connected to the heat preservation tube 7 .
[0029] The working principle and beneficial effects of the above technical solution are as follows: by rotatably connecting the insulation tube 7 and the collar 8, it is convenient to rotate the insulation tube 7, thereby driving the heating barrel 2 and the condensing box 6 to rotate and adjust their positions.
[0030] In one embodiment: a return pipe 9 is fixedly connected to the lower surface of the condensing box 6 and communicated therewith, the other end of the return pipe 9 is fixedly connected to and communicated with the heating barrel 2, and the end of the return pipe 9 connected to the heating barrel 2 has a first height, and the end of the connecting pipe 3 located in the heating barrel 2 has a second height, and the first height is lower than the second height.
[0031] The working principle and beneficial effects of the above technical solution are as follows: the condensed water falling into the condensation box 6 flows back into the heating barrel 2 through the reflux pipe 9. Since the first height of the reflux pipe 9 is lower than the second height of the connecting pipe 3, the condensed water flowing back into the heating barrel 2 can be stored.
[0032] In one embodiment: two mounting plates 10 are fixedly connected to the inner top of the condensation box 6, a rotating block 11 is rotatably connected between the two mounting plates 10, a cover plate 12 is fixedly connected to the rotating block 11, the cover plate 12 is located directly below the exhaust hole, and one end of the rotating block 11 away from the cover plate 12 is fixedly connected to a limiting plate 13, and one end of the limiting plate 13 away from the cover plate 12 is against the inner top of the condensation box 6.
[0033] The working principle and beneficial effects of the above technical solution are as follows: when the condensation box 6 is located at the top, the cover plate 12 sags under the action of gravity until the limit plate 13 and the inner top of the condensation box 6 are against each other. At this time, the cover plate 12 and the inner top of the condensation box 6 form an acute angle, that is, during heating, the rising steam can be blocked to increase the probability of condensation of the steam and reduce the loss of water resources. When cold water is added, the flow direction of the water can be changed to prevent it from entering the guide pipe 5. At the same time, after the condensation box 6 is rotated to the bottom, the cover plate 12 is closed under the action of gravity to block the exhaust hole, so that the condensation box 6 has a storage function. At the same time, the cover plate 12 can be pushed upward to discharge excess water, further improving the practicality of the condensation box 6.
[0034] In one embodiment, a rubber ring 14 is fixedly connected to the inner top of the condensation box 6, and the rubber ring 14 is concentrically arranged with the exhaust hole.
[0035] The working principle and beneficial effects of the above technical solution are as follows: the rubber ring 14 can ensure the sealing effect of the condensation box 6 and prevent water from leaking out of the condensation box 6.
[0036] In one embodiment, handles 15 are fixedly connected to both sides of the condensation box 6 , and each handle 15 is provided with anti-slip grooves.
[0037] The working principle and beneficial effects of the above technical solution are as follows: the setting of the handle 15 facilitates the staff to rotate the condensation box 6, and the anti-slip pattern can increase the friction between the handle 15 and the staff's hand.
[0038] In one embodiment: at least one limiting portion is provided on the insulation portion, and the limiting portion includes a first limiting block 16, two second limiting blocks 17 and a limiting rod 18. The first limiting block 16 is fixedly connected to the insulation tube 7, and each second limiting block 17 is fixedly connected to the corresponding collar 8. The first limiting block 16 and the second limiting block 17 are both provided with through holes for the limiting rod 18 to pass through.
[0039] The working principle and beneficial effects of the above technical solution are as follows: by passing the limit rod 18 through the two second limit blocks 17 and the through holes on the first limit block 16 , the insulation tube 7 can be locked relative to the sampler body 1 .
[0040] In one embodiment, the number of the limiting portions is set to two, and the two limiting portions are symmetrically arranged.
[0041] The working principle and beneficial effects of the above technical solution are as follows: the two symmetrically arranged limiting parts can further improve the stability after limiting.
[0042] In one embodiment, the cross section of the end of the pipe body of the flow guide pipe 5 extending inside the condensation tank 6 is arranged in an isosceles trapezoidal shape.
[0043] The working principle and beneficial effects of the above technical solution are as follows: by setting the cross-section of the end of the pipe body of the guide pipe 5 to an isosceles trapezoid, the gradually narrowing pipe mouth can slow down the flow rate of the cold water, so that it can perform sufficient heat exchange.
[0044] In one embodiment: a support frame 19 is fixedly connected to the lower side of each collar 8 , and a mounting hole for inserting a positioning bolt is provided on the support frame 19 .
[0045] The working principle and beneficial effects of the above technical solution are as follows: the support frame 19 can prop up the entire device to avoid damage to the sampler body 1, and bolts can be inserted into the mounting holes for fixing, thereby further improving the stability of the device.
[0046] Working principle and usage process:
[0047] When the temperature is low, first connect it to the external steam pipe through the threaded part of the connecting pipe 3, and transport the high-temperature steam into the insulation pipe 7 through the inlet pipe 4, and exchange heat with the pipe body of the hand-cranked sampler and the oil slurry inside, so as to increase the temperature of the oil slurry in the pipe body to above the solidification point, so that the staff can smoothly take samples in cold weather. The steam passing through the insulation pipe 7 continues to rise and is transported to the condensation box 6 through the guide pipe 5. Part of the steam is discharged from the exhaust hole 7, and the rest is condensed into liquid and falls back into the condensation box 6. The narrower pipe mouth at the upper end of the guide pipe 5 can prevent the condensed water from falling directly, thereby ensuring the heating efficiency. The condensed water flows back to the heating barrel 2 through the reflux pipe 9. Since the first height of the reflux pipe 9 is lower than the second height of the connecting pipe 3, the condensed water flowing back to the heating barrel 2 is stored.
[0048] When the temperature is high, pour cold water from the exhaust hole 7, and the inclined cover plate 12 changes the flow direction of the cold water, so that the cold water does not enter the guide tube 5, but enters the heating barrel 2 through the return pipe 9, and mixes with the original condensed water in the heating barrel 2. Then, hold the handle 15 and apply force to rotate the condensation box 6, the heating barrel 2 and the insulation tube 7 as a whole around the sampler body 1 for half a circle, drive the heating barrel 2 to move upward, and the cold water in the heating barrel 2 enters the insulation tube 7 through the inlet pipe 4, cools the tube body of the sampler body 1 and the oil slurry inside, and then is discharged into the condensation box 6 through the guide tube 5. The gradually narrowing mouth of the guide tube 5 can slow down the flow rate of water, so that The cold water can fully exchange heat with the tube body of the sampler main body 1 and the oil slurry inside, and then enter the condensation box 6. At this time, the cover 12 in the condensation box 6 is closed under the action of gravity, and the exhaust hole is blocked, so that the condensation box 6 can store the inflowing water. When it needs to be used again, the condensation box 6, the heating barrel 2 and the insulation tube 7 are rotated half a circle with the sampler main body 1 as the axis, and the water is re-introduced into the heating barrel 2 for the next sampling. At the same time, if extremely hot weather is encountered, the cover 12 can be pushed upward from the exhaust hole when the condensation box 6 is at the bottom to discharge the water with higher temperature in the box, and then re-add cold water.
[0049] The utility model uses the mutual cooperation of the temperature control part and the heat preservation part. When the temperature is low, high-temperature steam can be passed into the heat preservation part through the temperature control part to raise the temperature of the oil slurry to above the freezing point, which is convenient for sampling. At the same time, through the cooperation of the temperature control part and the condensation part, when the temperature is high, cold water can be delivered to the heat preservation part by rotating and exchanging the positions of the condensation box 6 and the heating barrel 2, so as to cool the tube body of the sampler main body 1 and the oil slurry inside, thereby avoiding scalding of the staff and eliminating safety hazards.
