Description

Technical Field

[0001] This utility model relates to the field of carbon black production technology, and particularly to the field of carbon black product sampling technology, specifically an automatic reset device for a sampling cover. Background Technology

[0002] In the continuous production process of carbon black, it is necessary to sample and test the properties of the products to ensure that the final carbon black product indicators are controlled. For convenient sampling, sampling ports are usually pre-installed on vertical carbon black conveying pipelines, angled upwards. To prevent foreign objects from entering the vertical carbon black conveying pipeline through the sampling ports and contaminating the carbon black product, sampling caps are fitted to the sampling ports. During sampling, employees must first open the sampling cap, then hold the sampling cylinder in one hand and the sampling spoon in the other, using the spoon to remove the sample from the vertical carbon black conveying pipeline and pour it into the sampling cylinder. Finally, after placing the sampling spoon back in place, the sampling cylinder cap must be immediately removed to close the sampling cylinder. The sampling cap must also be replaced by placing it back on the sampling port. However, in actual sampling, employees often forget to replace the sampling cap on the sampling port due to negligence, allowing foreign objects to enter the vertical carbon black conveying pipeline through the sampling port, thus affecting the quality of the final carbon black product. Summary of the Invention

[0003] In order to solve the problem that employees often forget to reset the sampling cap during actual sampling, this utility model provides an automatic sampling cap reset device.

[0004] This utility model is achieved using the following technical solution:

[0005] An automatic reset device for a sampling cover. In this device, a sampling pipe opening is reserved on a vertical carbon black conveying pipe and is arranged obliquely upward. The sampling cover is arranged on the sampling pipe opening. The device includes a rotating rod, a U-shaped cover handle, and a T-shaped vertical bracket composed of a horizontal bracket and a vertical bracket. Left and right fixed pulleys are respectively arranged at the left and right ends of the horizontal bracket. A traction rope is arranged on the left and right fixed pulleys. A counterweight is arranged at the right end of the traction rope. The left end of the traction rope is connected to one end of the rotating rod. The other end of the rotating rod is hinged to the vertical bracket of the T-shaped vertical bracket through a first hinge shaft, and the first hinge shaft is arranged in the front-rear direction. The rotating rod is located above the sampling pipe opening. The right end of the upper surface of the sampling cover is connected to one end of the rotating rod through a connecting rope. One end of the U-shaped cover handle is fixed to the left end of the upper surface of the sampling cover. The other end of the U-shaped cover handle is hinged to one end of an avoidance member through a second hinge shaft, and the hinge shaft is arranged in the front-rear direction. The other end of the avoidance member is fixed to the outer wall of the vertical carbon black conveying pipe and is arranged higher than the sampling pipe opening. A hook for hanging a sampling spoon is arranged in the middle of the rotating rod. A limiting rod is vertically fixed on the vertical bracket of the T-shaped vertical bracket and is located below the other end of the rotating rod. When the sampling spoon is hung on the rotating rod, the counterweight on the left end of the traction rope is heavier than the counterweight on its right end, the counterweight moves upward, the other end of the U-shaped cover handle rotates downward around the second hinge shaft, and the rotating rod rotates downward around the first hinge shaft until the right end of the rotating rod is supported by the limiting rod. At this time, the sampling cover just resets to cover the sampling pipe opening. When the sampling spoon is removed from the rotating rod, the counterweight on the left end of the traction rope is lighter than the counterweight on its right end, the counterweight moves downward, the rotating rod rotates upward around the first hinge shaft, and the other end of the U-shaped cover handle rotates upward around the second hinge shaft, and the sampling cover is in an open state.

[0006] During use, fix the T-shaped vertical bracket to the ground. When sampling, an employee holds a sampling cylinder in one hand and removes the sampling spoon from the rotating rod with the other hand. Since the counterweight on the right side of the T-shaped vertical bracket is greater than the counterweight on its left side, the counterweight moves downward, the other end of the U-shaped cover handle rotates upward around hinge shaft B, the rotating rod rotates upward around hinge shaft A, and the sampling cover is fully opened. Then the employee holds the sampling spoon and starts to pour the sample into the sampling cylinder. Finally, the employee hangs the sampling spoon on the rotating rod. When the counterweight on the left side of the T-shaped vertical bracket is greater than the counterweight on the right side and the right end of the rotating rod is supported by the limiting rod, the sampling cover just covers the sampling pipe opening, completing the reset of the sampling cover.

[0007] Furthermore, the handle of the sampling spoon is a "dry" - shaped handle, and the hook is an inverted Y - shaped hook with a bent portion extending upward from its bottom end that is adapted to the top end of the sampling spoon handle. The structure is simple and convenient for hanging or removing the sampling spoon.

[0008] Furthermore, a first hanging ring is fixed to the right end of the upper surface of the sampling cover, a second hanging ring is fixed to one end of the rotating rod, and the two ends of the connecting rope are respectively connected to the first hanging ring and the second hanging ring. The structure is made specific and standardized.

[0009] Furthermore, the left end of the traction rope is connected to the second lifting ring, making the structure more specific and standardized.

[0010] Furthermore, a supporting web is provided between the left end of the horizontal support and the top of the vertical support to improve the stability of the overall device.

[0011] Furthermore, the vertical support is fixed at 2 / 3 of the horizontal position from left to right of the horizontal support, making the structure more specific, standardized, and rational.

[0012] The beneficial effects of this utility model are as follows: The automatic sampling cap reset device of this utility model ingeniously utilizes the principle of counterweight and adopts a mechanical structure to realize the automatic reset of the sampling cap, effectively preventing product contamination caused by employees forgetting to reset the sampling cap; at the same time, the device has a simple structure, is easy to operate and maintain, and has a low cost.

When the sampling spoon 2 is hung on the rotating rod 8, the counterweight weight at the left end of the traction rope 7 is greater than the counterweight weight at its right end, and the counterweight 3 moves upward, causing the U-shaped cover handle 13 to... The other end rotates downward around the second hinge axis 12, and the rotating rod 8 rotates downward around the first hinge axis 11 until the right end of the rotating rod 8 is supported by the limiting rod 9. At this time, the sampling cover 1 is reset and placed at the sampling tube opening 16.

The rotating rod 8 rotates upward around the hinge axis A, and the sampling cover 1 is fully opened. Then, the employee holds the sampling spoon 2 and begins to pour the sample into the sampling cylinder. Finally, the employee hangs the sampling spoon 2 on the rotating rod 8. When the left side of the T-shaped vertical support 4 has a larger counterweight than the right side, and the right end of the rotating rod 8 is supported by the limiting rod 9, the sampling cover 1 is exactly placed on the sampling tube opening 16, completing the reset of the sampling cover 1.

[0023] In specific implementation, the handle of the sampling spoon 2 is a "dry" - shaped handle, and the hook 17 is an inverted Y - shaped hook 17 with a bent portion 18 extending upward at its bottom end, which is adapted to the top end of the handle of the sampling spoon 2. The structure is simple and convenient for hanging or removing the sampling spoon 2.
