Description

Technical Field

[0001] The utility model relates to the technical field of lime production equipment, in particular to an automatic lime sampling device. Background Art

[0002] White ash is a commonly used additive in steelmaking. During the steelmaking process, it mainly plays a series of roles, such as regulating furnace temperature, desulfurization and dephosphorization, promoting slag formation, adjusting chemical reaction balance, improving molten steel quality, and reducing pollutant emissions. It can be said that white ash is an indispensable part of steelmaking. In the production process of white ash, in order to ensure that its quality meets the needs of steelmaking, it is necessary to randomly sample the white ash and determine the quality of the white ash through testing. At present, the sampling of white ash is generally done manually, which requires the staff to use tools to randomly sample the white ash during the transportation of white ash. Such operation greatly increases the workload of the staff. Therefore, some workshops will set up an automatic sampling auxiliary equipment on the white ash conveyor belt. These auxiliary equipment generally only have the function of collecting samples. After sampling, the staff also need to hold the container to hold the white ash sample collected by the auxiliary equipment. In the process of pouring the sample, the white ash sample will inevitably spill, which will pollute the workshop environment. In addition, the collected sample needs to be recovered with a container every time, which still brings great inconvenience to the sampling work. Utility Model Content

[0015] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, unless there is a conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-3As shown, the automatic lime sampling device described in this embodiment includes a belt conveyor 1. The belt conveyor 1 is provided with a mounting frame 2 that can be raised and lowered above its belt. A rotating roller 3 is provided on the mounting frame 2. The lower end of the rotating roller 3 is provided with a sampling head 4 that rotates therewith, and a sampling bag 5 is fixed to the rear end of the sampling head 4.

[0018] The sampling head 4 is a hollow cylindrical structure, the left end of the sampling head 4 is in the shape of an inclined spike, the sampling bag 5 is sleeved and fixed on the right end of the sampling head 4, and the direction of the sampling head 4 with the spike is opposite to the conveying direction of the belt conveyor 1.

[0019] One end of the sampling bag 5 connected to the sampling head 4 is provided with an elastic leather ring 6 , and the leather ring 6 is tightly clamped around the end of the sampling head 4 .

[0020] The right end of the sampling head 4 is also provided with a tightening ring 7, which is sleeved on the outside of the sampling bag 2 and tightened on the right end of the sampling head 1. The tightening ring 7 plays a reinforcing role, thereby preventing the sampling bag 2 from falling off at the sampling head 4.

[0021] The rotating roller 3 is horizontally placed between the mounting frames 2 . A control motor 8 is provided on one side of the mounting frame 2 . The control motor 8 drives the rotating roller 3 to rotate inside the mounting frame 2 .

[0022] A vertical connecting rod 9 is provided at the lower end of the rotating roller 3 , and the sampling head 4 is installed at the lower end of the connecting rod 9 .

[0023] A bracket 10 is provided above the belt conveyor 1 , a lifting cylinder 11 is provided on the top of the bracket 10 , a piston rod of the lifting cylinder 11 is vertically downwardly arranged, and the mounting frame 2 is installed on the piston rod of the lifting cylinder 11 .

[0024] The working principle of the present invention is as follows: the ash is transported on the belt conveyor 1, thereby completing the transfer between various devices. During the transportation of the ash, when sampling is required, the control motor 8 is started and drives the rotating roller 3 to rotate. As the rotating roller 3 rotates, the end of the sampling head 4 with the spikes tilts downward toward the side of the belt conveyor 1, and then the piston rod of the lifting cylinder 11 extends and controls the sampling head 4 to move downward. As the end of the sampling head 4 with the spikes comes into contact with the ash on the belt conveyor 1, the control motor 8 drives the rotating roller 3 to rotate again, so that the sampling head 4 is adjusted to a horizontal state, and the lifting cylinder 11 stops working and makes the sampling head 4 in a horizontal state suspended above the belt, and the ash transported on it will enter the sampling head 4 along with the conveyor. After the sampling is completed, the lifting cylinder 11 stops working and makes the sampling head 4 in a horizontal state suspended above the belt, and the ash transported on it will enter the sampling head 4 along with the conveyor. The cylinder 11 controls the sampling head 4 to rise upward. At the same time, the control motor 8 controls the rotating roller 3 to rotate again, so that the end of the sampling head 4 with the spike is vertically facing upward. In this way, the white ash in the sampling head 4 will fall into the sampling bag 5 under the action of gravity. The staff will remove the tightening ring 7 and take off the sampling bag 5 on the sampling head 4 to obtain the white ash sample. After sampling, a new sampling bag 5 is replaced and tightened with the tightening ring 7 to repeat the sampling work. In order to realize the sampling work without stopping, multiple sets of sampling equipment can be set above the belt conveyor 1. By controlling each sampling head 4 to perform sampling work alternately, the staff can randomly sample the white ash in different transport sections. After multiple samplings are completed, the staff can remove the samples of each batch in a unified manner. The whole process is convenient and fast, saving time and effort.
