Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing, in particular to a steam cut-off structure for mineral processing. Background Art

[0002] Mineral processing is a key discipline in the development and utilization of mineral resources. It involves a series of ore handling and processing processes to achieve efficient ore utilization and economic growth. With the advancement of science and technology, automation technology has been widely used in mineral processing, greatly improving production efficiency and processing quality. Certain steps in mineral processing require steam pipes to provide heat, which requires the installation of steam shutoff structures to achieve opening and closing.

[0003] However, when using traditional steam shut-off structures for mineral processing, the frequent opening and closing of the shut-off valve body causes rapid changes in steam flow and pressure in the pipeline, resulting in stress concentration at the connection between the valve and the pipeline. Over time, this stress concentration may cause fatigue damage at the connection and loosening of the threaded connection between the connection and the pipeline.

[0004] For example, in some mineral processing processes (mainly ore drying, preheating, smelting, etc.), high-temperature steam is required. After these operations are stopped, it is necessary to disconnect the internal steam supply of the steam pipeline to avoid problems such as ore agglomeration caused by condensed water. Utility Model Content

[0005] The utility model discloses a steam shut-off structure for mineral processing, which aims to solve the technical problem that when a conventional steam shut-off structure for mineral processing is used, frequent opening and closing of a shut-off valve body causes rapid changes in the steam flow and pressure in a pipeline, thereby generating stress concentration at the connection between the valve and the pipeline. In the long run, this stress concentration may cause fatigue damage to the connection and loosening of the screw connection between the connection and the pipeline.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A steam shut-off structure for mineral processing comprises a pipeline body and a connecting piece installed on the pipeline body, the connecting piece being provided with a shut-off valve, and further comprising: a reinforcement mechanism: the reinforcement mechanism comprises a first flange arranged on both sides of the connecting piece, a second flange is provided on the pipeline body on both sides of the connecting piece, three equidistantly distributed mounting grooves are provided on the outer walls on opposite sides of the two second flanges, the same connecting rod is installed on the mounting grooves at two relative positions on the two second flanges, and the three connecting rods are equidistantly distributed on the outside of the connecting piece; a locking mechanism: the locking mechanism is arranged inside the mounting groove.

[0008] In this solution, the reinforcement mechanism is set up to make the connection between the connector and the pipeline body more stable. Specifically, the first flange on the pipeline body and the second flange on the connector are fixed and limited by pulling three equidistantly distributed connecting rods, and the connection position is reinforced from a triangular distribution range, which to a certain extent offsets the sudden stress change during the valve opening and closing process, relieves the connection pressure between the connector and the pipeline body, and avoids loose installation of the connector.

[0009] In a preferred embodiment, the locking mechanism includes a first limiting hole arranged on the outer wall of the connecting rod near both ends, a limiting sleeve is provided inside the mounting groove, the limiting sleeve is socketed with the connecting rod, a second limiting hole is installed on the outer wall of the limiting sleeve, and an insertion hole is provided on the bottom inner wall of the mounting groove, and the same limiting bolt is inserted into the inner walls of the first limiting hole, the second limiting hole and the insertion hole.

[0010] Through the limit connection, the two ends of the connecting rod are locked with the installation grooves on the pipe body, thereby clamping the connecting piece installed between the pipe bodies, so that the connecting rod exists in the form of connecting ribs on the outside of the connecting piece. The effective locking ensures the stability of the reinforcement effect.

[0011] As can be seen from the above, a steam shutoff structure for mineral processing includes a pipe body and a connector mounted on the pipe body, the connector being provided with a shutoff valve, and further comprising: a reinforcement mechanism: the reinforcement mechanism includes a first flange disposed on both sides of the connector, a second flange being provided on the pipe body on both sides of the connector, three equally spaced mounting grooves being provided on the outer walls on opposite sides of the two second flanges, the same connecting rod being mounted on the mounting grooves at two opposite positions on the two second flanges, and the three connecting rods being equally spaced on the outside of the connector; and a locking mechanism: the locking mechanism being provided inside the mounting groove. The steam shutoff structure for mineral processing provided by the utility model has the technical effect of offsetting the stress exerted on the connector during the valve opening and closing process, thereby preventing the screws from loosening due to stress changes.

[0018] The steam shut-off structure for mineral processing disclosed by the utility model is mainly applied to traditional steam shut-off structures for mineral processing. When used, the frequent opening and closing of the shut-off valve body will cause rapid changes in the steam flow and pressure in the pipeline, thereby generating stress concentration at the connection between the valve and the pipeline. In the long run, this stress concentration may cause fatigue damage to the connection and loosening of the screw connection between the connection and the pipeline.

[0021] Locking mechanism: The locking mechanism is arranged inside the mounting slot.

[0022] The two ends of the connecting rod 7 pass through the two first flanges 4 and the two second flanges 5 respectively.

[0023] In this solution, the reinforcement mechanism is set up to make the connection between the connector 2 and the pipe body 1 more stable. Specifically, the first flange 4 on the pipe body 1 and the second flange 5 on the connector 2 are fixed and limited by pulling by three equidistantly distributed connecting rods 7, and the connection position is reinforced from a triangular distribution range, which to a certain extent offsets the sudden stress change during the valve opening and closing process, relieves the connection pressure between the connector 2 and the pipe body 1, and avoids loose installation of the connector 2.

[0025] Specifically, through the limiting connection, the two ends of the connecting rod 7 are locked with the installation grooves on the pipe body 1, thereby clamping the connecting piece 2 installed between the pipe body 1, so that the connecting rod 7 exists in the form of a connecting rib on the outside of the connecting piece 2.

By wrapping the materials of the screw 6 and the limit bolt 10, they can be prevented from being exposed to the air and contacting water to prevent them from rusting, thereby extending the service life of the screw 6 and the limit bolt 10.

[0029] Working principle: When in use, first install the stop valve 3 on the connector 2, debug the working status of the stop valve 3, and make sure that the installed stop valve 3 can play a shut-off role on the pipeline body 1, and then use the first flange 4 and the second flange 5 to install the connector 2 between the pipeline body 1. After the installation is completed, the three connecting rods 7 are correspondingly inserted into the first flange 4 and the second flange 5, and the limiting sleeves 11 and the limiting bolts 10 in the locking structure are used to lock the two ends of the connecting rod 7, so that the connecting rods 7 distributed at equal distances on the outside of the connector 2 play a role of connection reinforcement, thereby offsetting part of the stress borne by the connector 2.
