DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The present invention provides a sampling device for a combustion tank, comprising a combustion tank 1, which is used to heat asphalt or modified asphalt. During operation, the sampling device is used to sample the asphalt or modified asphalt at the bottom of the combustion tank 1, so as to detect various indicators of the asphalt or modified asphalt. The sampling device further comprises a sampling chamber 2 provided on the top of the combustion tank 1, a lifting mechanism 3 provided in the sampling chamber 2, a sampling mechanism 4 provided at the output end of the lifting mechanism 3, and a partition 5 detachably provided in the sampling chamber 2. The sampling chamber 2 is provided with a closed door 21. The sampling mechanism 4 comprises a shell 41, a telescopic assembly 42 provided in the shell 41, and a valve body 43 provided at the lower end of the telescopic assembly 42. A material port 44 is provided at the bottom of the shell 41, and the valve body 43 is used to open or close the material port 44.

[0025] In actual use, the combustion tank 1 is connected to the sampling chamber 2. When sampling, the lifting mechanism 3 drives the sampling mechanism 4 to descend to the bottom of the combustion tank 1, and the telescopic component 42 is pressed and moves upward, so that the valve body 43 is away from the material port 44, the material port 44 is opened, and the asphalt in the combustion tank 1 enters the shell 41 through the material port 44; after a period of time, the lifting mechanism 3 drives the sampling mechanism 4 to rise, and the telescopic component 42 is reset, so that the valve body 43 is close to the material port 44, and the material port 44 is closed to prevent the asphalt in the shell 41 from flowing out of the material port 44; when the sampling mechanism 4 rises to the sampling chamber 2, the closed door 21 is opened, and the partition 5 is placed in the sampling chamber 2 so that the partition 5 is located at the shell 41 Below, the sample tank 8 for holding asphalt is placed on the partition 5, and the telescopic component 42 is lifted upward by a tool, the valve body 43 is away from the material port 44, and the asphalt in the shell 41 flows downward to the sample tank 8 through the material port 44, so as to realize the transfer of the asphalt in the shell 41 to the sample tank 8. The operation is convenient, and the whole process only needs to be operated in the sampling chamber 2. There is no need to take out the sampling mechanism 4, which can avoid asphalt dripping and polluting the working environment, and the operator's hands do not need to directly contact the shell 41, which can avoid burns caused by high temperature. In addition, the sampling mechanism 4 is driven to move up and down by the lifting mechanism 3, which can reduce the operator's labor intensity to a certain extent.

[0026] In the above, the tool can be a long rod with a certain rigidity. During operation, one end of the long rod is held and lifted upward so that the other end of the upper rod applies pressure to the telescopic component 42 to push the valve body 43 away from the material port 44.

[0027] In a preferred embodiment, see Figure 4 、 5 The telescopic assembly 42 includes a vertical rod 421 and a spring 422. The vertical rod 421 is slidably connected to the housing 41, and the top of the vertical rod 421 extends outside the housing 41. A retaining ring 423 is provided on the top of the vertical rod 421. The spring 422 is mounted on the vertical rod 421, and the two ends of the spring 422 are respectively in contact with the retaining ring 423 and the housing 41. A hanging ring 424 is provided on the top of the vertical rod 421. In a natural state, the elastic force of the spring 422 drives the valve body 43 downward, and the valve body 43 closes the feed port 44. When the vertical rod 421 is compressed, the spring 422 is compressed and contracts, and the vertical rod 421 moves upward, driving the valve body 43 away from the feed port 44. At this time, the feed port 44 is open, and asphalt can flow into the housing 41 through the feed port 44, or flow out of the housing 41. When transferring the asphalt in the shell 41, a tool is inserted into the lifting ring 424 and the lifting ring 424 is lifted upward to move the vertical rod 421 upward, the material port 44 is opened, and the asphalt in the shell 41 flows downward through the material port 44 into the sample tank 8. The above arrangement facilitates the transfer of asphalt in the shell 41.

[0028] Alternatively, as Figure 5As shown, the lower end of the vertical rod 421 extends to the outside of the material port 44. When the shell 41 reaches the bottom of the combustion tank 1, the vertical rod 421 is pressed to move upward to drive the valve body 43 to move upward. The valve body 43 moves away from the material port 44, and the material port 44 opens.

[0029] Optionally, the valve body 43 is located at the bottom of the vertical rod 421, and the bottom of the valve body 43 extends to the outside of the material port 44. When the shell 41 reaches the bottom of the combustion tube, the valve body 43 moves upward under pressure, and the valve body 43 moves away from the material port 44, and the material port 44 opens.

[0030] Further, see Figure 2 、 3 , further comprising a positioning fork 6, comprising a U-shaped frame 61 and an insertion rod 62 disposed in the middle of the U-shaped frame 61, the insertion rod 62 being insertable into the lifting ring 424; a socket 22 for fixing the U-shaped frame 61 is disposed on the inner wall of the sampling chamber 2. The lifting mechanism 3 lifts the housing 41 to the sampling chamber 2, with the lifting ring 424 positioned at the same level as the socket 22. The insertion rod 62 is correspondingly inserted into the lifting ring 424, and the U-shaped frame 61 is inserted into the socket 22, thereby locking the position of the positioning fork 6 and, in turn, the position of the vertical rod 421. At this point, the lifting mechanism 3 drives the housing 41 downward a short distance, causing the housing 41 and the vertical rod 421 to move relative to each other, and the valve body 43 to move away from the material port 44, which opens the material port 44. At this point, the asphalt in the housing 41 flows to the sample tank 8 located below. The above arrangement facilitates the operator in opening the material port 44.

[0031] In the above, there are two sockets 22, and the two sockets 22 are symmetrically arranged. A positioning hole 221 matching the U-shaped frame 61 is provided in the socket 22, and two positioning holes 221 are inserted on both sides of the U-shaped frame 61 to ensure the stability of the installation of the positioning fork 6. After the asphalt transfer is completed, only the positioning fork 6 needs to be pulled out, which is simple to operate.

[0032] In a preferred embodiment, see Figure 5 The bottom of the shell 41 is provided with a funnel-shaped lower shell 45, and the feed port 44 is located at the bottom of the lower shell 45. Several legs 46 are provided at the bottom of the shell 41, and the bottom of the lower shell 45 is located above the bottom of the legs 46. When the shell 41 reaches the bottom of the combustion tank 1, the legs 46 support the shell 41, so that the feed port 44 is at a certain distance from the bottom of the combustion tank 1, facilitating the entry of asphalt into the shell 41 through the feed port 44. Since the vertical rod 421 extends outside the feed port 44, it is pressurized and moves upward, causing the valve body 43 to move away from the feed port 44, and the feed port 44 opens.

[0033] The funnel-shaped lower shell 45 facilitates the downward convergence of asphalt during the transfer of asphalt from the shell 41, thereby draining the asphalt from the shell 41. Preferably, the inlet 44 is a downwardly converging tapered hole, and the valve body 43 is a downwardly converging cone. When the valve body 43 engages with the inlet 44, the inlet 44 is closed; when the valve body 43 moves away from the inlet 44, the inlet 44 is opened.

[0034] In a preferred embodiment, see Figure 2 The lifting mechanism 3 includes a rotating shaft 31 rotatably connected to the sampling chamber 2, a suspension rope 32 wound around the rotating shaft 31, a drive motor 33 for driving the rotating shaft 31, and a transition wheel 34 located below the rotating shaft 31. The lower end of the suspension rope 32 is fixed to the housing 41. The drive motor 33 is fixed to the outer wall of the sampling chamber 2. One end of the suspension rope 32 is wound around the rotating shaft 31, and the other end is fixed to the housing 41 after passing through the transition wheel 34. The drive motor 33 drives the rotating shaft 31 to rotate forward and reverse, thereby reeling and unreeling the suspension rope 32, thereby achieving the lifting and lowering movement of the housing 41. The provision of the transition wheel 34 ensures that the housing 41 can be lifted and lowered along the centerline of the sampling chamber 2.

[0035] Preferably, two symmetrically arranged baffles 36 are provided on the rotating shaft 31 , and the sling rope 32 is wound between the two baffles 36 to limit the position of the sling rope 32 .

[0036] In a preferred embodiment, see Figure 2 、 4 A scraper cover 35 is provided below the rotating shaft 31. The scraper cover 35 has a conical structure and a through-hole in the middle thereof that matches the sling rope 32. The scraper cover 35 is fixedly mounted within the sampling chamber 2. During the sampling process, asphalt adheres to the sling rope 32. When the sling rope 32 is reeled in, the sling rope 32 contacts the edge of the through-hole to scrape off the asphalt on the sling rope 32, thereby preventing the asphalt from clumping around the reeled sling rope 32.

[0037] Specifically, a plurality of support rods 47 are provided on the top of the shell 41, and a hanging plate 48 is provided on the top of all the support rods 47. The hanging rope 32 is connected to the hanging plate 48, and the end of the hanging rope 32 is divided into three strands to be fixed on the hanging plate 48, thereby ensuring the stable lifting of the shell 41.

[0038] It should be noted that the hanging ring 424 is located between the hanging plate 48 and the top of the shell 41, and can provide enough space for the vertical rod 421 to slide up and down.

[0039] In a preferred embodiment, see Figure 4 The bottom of the sampling chamber 2 is provided with a guide cover 7, which is a truncated cone structure. The guide cover 7 guides the upward movement of the housing 41 to prevent the housing 41 from being offset and stuck at the position where the sampling chamber 2 is connected to the combustion tank 1.

[0040] In a preferred embodiment, see Figure 1 、 3 The inner wall of the sampling chamber 2 is provided with two symmetrically arranged chutes 23, and the two sides of the partition 5 are slidably connected to the two chutes 23. The partition 5 can be pulled out to facilitate installation and removal. During the sampling process, the partition 5 is removed to prevent it from obstructing the upward and downward movement of the sampling mechanism 4. During the asphalt transfer process, the partition 5 is installed and the sample can 8 can be placed on the partition 5 to reduce the labor intensity of the workers.

[0041] In a preferred embodiment, a first insulation layer is provided at the bottom of the partition 5 to prevent the partition 5 from being heated and causing burns to the operator; a second insulation layer is provided on the outside of the sampling chamber 2; and a third insulation layer is provided on the outside of the closed door 21. These arrangements prevent heat loss and prevent burns to the operator from touching the sampling chamber 2 or the closed door 21, thereby improving user safety. The first, second, and third insulation layers are not shown in the accompanying drawings.

[0042] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
