Abstract
Description
Technical Field
[0001] This utility model belongs to the field of auxiliary equipment technology in the metallurgical industry, and specifically relates to a sample cooling device. Background Technology
[0002] In the steelmaking process, it is necessary to accurately determine the composition of molten steel through steel samples. The commonly used sampling method is as follows: after inserting the rapid molten steel sampler into the special molten steel sampling gun, the molten steel sampler is tilted at 60-65° and inserted into the molten steel to a depth of more than 350mm, and the sampling time is 4-6s. After the sampler is taken out of the metal furnace or ladle, it is gently tapped on the ground and the steel sample will fall to the ground.
[0003] The traditional method of sampling and cooling steel samples involves placing the sampler on the ground after taking the sample and gently tapping it with a hammer. Once the sample falls to the ground, it is held in place with special clamps. Then, a small hammer is used to gently tap the sample, causing the quartz sand and metal shell surrounding it to fall off. Finally, the red-hot steel sample is cooled in water before being sent to a laboratory for analysis of the molten steel's composition, thus providing guidance for the steelmaking process.
[0004] Traditional steel sample crushing and cooling devices have the following disadvantages: 1. The crushing hammer, clamps, and water buckets for cooling the steel samples are all placed on the ground, requiring personnel to squat while crushing and cooling the samples, which easily leads to fatigue and is not in line with human biomechanics. 2. The red-hot steel sample shell and waste such as quartz sand used to wrap the steel sample accumulate on the ground, posing a risk of burns and falls if personnel step on the hot steel sample shell. 3. When clamping the steel sample and placing it in the cooling water bucket, the steel sample is prone to falling into the water tank, wasting time and affecting normal sample release operations.
[0005] Therefore, there is an urgent need for a sample crushing and cooling device to facilitate the crushing and cooling of steel samples and to facilitate the collection of steel sample shells and other debris. Utility Model Content

[0008] A sample cooling device is also provided at one end of the operating table. The sample cooling device includes a cooling platform and a draining device that is detachably connected to the cooling platform. The cooling platform is located on the upper surface of the operating table. A lifting structure is provided below the operating table at a position corresponding to the cooling platform. The lifting structure extends into a receiving box provided below the operating table. The receiving box is a hollow structure.
[0009] A cooling cylinder is installed inside the receiving box. The cooling cylinder is fitted with the receiving box with a clearance. The bottom of the cooling cylinder is detachably connected to the lifting structure.
[0010] Furthermore, a cleaning area is provided on the side of the operating table away from the cooling platform. The cleaning area is concave in shape, with a flat end near the cooling platform and an inclined end away from the cooling platform.
[0011] Several channel holes are arranged in a matrix on the inclined end. A buffer box is provided below the channel holes. The size of the buffer box is larger than the size of the channel hole matrix. The buffer box is connected to the operating table by welding or bolting. A conduit is provided below the buffer box.
[0012] Furthermore, the cooling platform includes a base platform and support structures disposed at the four corners of the base platform. The upper end of the support structure is connected to the support platform, and a threaded channel is provided at the center of the support platform.
[0013] The draining device is threadedly connected to a threaded hole located at the center of the support platform.
[0014] Furthermore, the draining device includes a connecting rod and a receiving plate that is fixedly or detachably connected to the connecting rod, and the receiving plate has a plurality of drainage holes;
[0015] The draining device achieves height adjustment through a support structure, which is an electro-hydraulic telescopic rod structure.
[0016] Furthermore, the cooling platform is detachably connected to the operating table, and a through hole is provided at the center of the cooling platform. The through hole is coaxially arranged with the cooling cylinder channel opened at the upper end of the operating table, and the cooling cylinder channel corresponds to the cooling cylinder.
[0017] Furthermore, the rear end baffle of the protective baffle is connected to the left and right baffles by bolts.
[0018] The height of the rear end baffle is higher than the height of the left and right baffles;
[0019] The rear end baffle can be folded toward the side where the operating table is located, and the width of the rear end baffle is the same as the width of the operating table plane.
[0020] Furthermore, the lifting structure located below the operating table and corresponding to the cooling platform is a hydraulic cylinder. The output end of the hydraulic cylinder cooperates with the positioning hole opened at the bottom of the cooling cylinder, and the cooling cylinder is raised or lowered by lifting the hydraulic cylinder.
[0021] Furthermore, the support column at the bottom of the operating table is connected to the moving wheels, and the support column adopts a lifting structure.

At this time, the water draining device is raised or lowered by the support structure, which is an electric hydraulic telescopic rod structure. The personnel hold the small hammer and tap the head of the sampler in a normal standing posture to knock out the red-hot sample shell. The red-hot steel sample is picked up with clamps and placed into the cooling cylinder. After the steel sample cools down, the water draining device is lifted to extract and send the steel sample. The steel sample shell and quartz sand will not splash to the ground when the sample is smashed. After the sample is sent, the debris on the table is collected into the buffer box under the operating table through several channels arranged in a matrix on the inclined end.
[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0025] In this invention, the operator stands upright and gently taps the head of the sampler with a small hammer to remove the red-hot sample shell. The hot steel sample is then picked up with clamps and placed in a cooling cylinder. Once cooled, the sample is lifted from the drainer and ready for delivery. During operation, the operator does not need to repeatedly squat and stand up. The steel sample shell and quartz sand do not splatter onto the ground during tapping. After delivery, debris on the table is collected through an opening into a sample-receiving bucket below the table, preventing burns and slips caused by stepping on the hot steel shell. This significantly improves work efficiency and safety. Attached Figure Description
