Description

Technical Field

[0001] The utility model relates to the technical field of sintered ore sampling, and more specifically, to a feeding device for high-rise sampling. Background Art

[0002] In steel smelting workshops, the sinter ore sampling platform is high above the ground, typically three stories high, more than ten meters tall. Due to the site's spatial environment, the existing steel staircases used for ascending and descending are installed at a steep angle and have narrow steps. Furthermore, since sinter ore sampling is frequent, occurring every four hours and each sample typically weighing 20kg or more, workers must carry the samples downstairs after sampling. This heavy load is difficult to carry and poses a significant safety hazard.

[0003] Therefore, it is urgent to design a high-rise sampling feeding device to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-rise sampling unloading device for the above-mentioned deficiencies in the prior art, which uses a chute to transport samples instead of traditional manual carrying of samples downstairs, thereby effectively improving production safety.

[0005] The technical solution of the present utility model is as follows: a discharge device for high-rise sampling, comprising a down chute and a sample locking cabinet, the down chute being an inclined pipe arranged obliquely, one end of the down chute extending to the sampling platform and connected thereto, the other end extending to the top of the sample locking cabinet and connected thereto, one end of the discharge pipe being connected to a conical feed hopper, the top of the feed hopper being hinged with a hopper door covering it, the hopper door and the feed hopper being locked and connected by a hopper door padlock; a drop pipe connected to the down chute is provided in the sample locking cabinet, a sample receiving bucket is movably placed in the sample locking cabinet below the drop pipe, two cabinet doors are hinged on the front of the sample locking cabinet, the cabinet doors are locked and connected by a cabinet door padlock.

[0006] As a further improvement, at least two buffer brushes are provided in the drop tube. The buffer brushes are plastic brushes and are staggeredly installed on the inner wall of the drop tube.

[0007] Furthermore, a hose is connected to the bottom of the drop pipe, a cover is connected to the bottom of the hose, two ends of the hose are connected to the drop pipe and the bottom of the cover respectively, and the cover is attached to the top of the sample receiving barrel.

[0008] Furthermore, springs are provided on the tops of the sample lock cabinets on both sides of the drop tube, and the bottoms of the springs are connected to the cover plate.

[0011] Beneficial Effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The high-rise sampling unloading device of the present invention sets a down chute between the sampling platform and the ground. When sampling, the staff only needs to go up to the sampling platform alone to take samples from the sintering furnace, then open the hopper door, pour the sample into the down hopper, and the sample falls into the sample receiving bucket along the down chute, and then lock the hopper door to prevent other impurities from entering; then the staff goes down to the ground, opens the cabinet door, and takes out the sample. The use of the chute to transport replaces the traditional manual carrying of samples downstairs, effectively improving production safety, and the hopper and the sample receiving bucket are locked by padlocks to prevent impurities from contaminating the sample. At the same time, the sample is controlled, that is, the sample is a real and reliable sample.

[0014] 2. The high-rise sampling discharge device of the present invention provides a cover plate under the discharge pipe, and presses the cover plate against the top of the sample receiving barrel by a spring, thereby covering the top of the feed inlet on the top of the sample receiving barrel. This not only further prevents impurities from entering the sample receiving barrel, but also plays a role in pressing and positioning the sample receiving barrel, thereby preventing the sample receiving barrel from tipping over due to the impact of the sample.

[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0021] See Figures 1-4, A blanking device for high - rise sampling of the utility model includes a down - chute pipe 1 and a sample - locking cabinet 2. Among them, the down - chute pipe 1 is an inclined pipe arranged obliquely, which can effectively slow down the flow rate of the sample and avoid high - speed impact on the sample - receiving bucket 7. One end of the down - chute pipe 1 extends to and is connected to the sampling platform, and the other end extends to and is connected to the top of the sample - locking cabinet 2 to realize the installation and fixation of the down - chute pipe 1. One end of the blanking pipe 1 is connected with a conical feed hopper 3 to facilitate pouring the sample into the down - chute pipe 1. A hopper door 4 covering it is hinged at the top of the feed hopper 3 to prevent on - site dust from entering the blanking chute pipe 1, resulting in the problem of sample contamination. The hopper door 4 and the feed hopper 3 are tightly locked and connected by a hopper - door padlock 5 to prevent others from falsifying and modifying the sample; A blanking pipe 6 communicating with the down - chute pipe 1 is arranged in the sample - locking cabinet 2. The blanking pipe 6 is a straight pipe arranged vertically downward to facilitate guiding the sample to the sample - receiving bucket 7. A sample - receiving bucket 7 is movably placed in the sample - locking cabinet 2 below the blanking pipe 6 for receiving the sample. Two cabinet doors 8 are hinged on the front of the sample - locking cabinet 2, and the cabinet doors 8 are tightly locked and connected by a cabinet - door padlock 9, so that the sample - receiving bucket 7 is locked in the sample - locking cabinet 2 to prevent on - site dust from entering the sample - receiving bucket 7 and also prevent others from falsifying.

[0022] For the high - rise sampling blanking device of the utility model, by setting the down - chute pipe 1 between the sampling platform and the ground, during sampling, only the staff needs to go up to the sampling platform alone to take samples from the sintering furnace, then open the hopper door 4, pour the sample into the blanking hopper 3, the sample falls along the down - chute pipe 1 into the sample - receiving bucket 7, and then lock the hopper door 4 to prevent other impurities from entering; Then the staff goes down to the ground, opens the cabinet door 8, and takes out the sample. Using the chute transportation to replace the traditional manual carrying of samples downstairs effectively improves production safety, and both the feed hopper 3 and the sample - receiving bucket 7 are locked by padlocks to avoid sample contamination by impurities and also make the sample controlled, that is, the sample is a true and reliable sample.

[0023] Preferably, at least two buffer brushes 10 are arranged in the blanking pipe 6. The buffer brushes 10 are plastic brushes and are stagger - installed on the inner wall of the blanking pipe 6.
