Description

Technical Field

[0001] This invention relates to the field of tailings backfilling operation technology, specifically to a deep cone thickener condition monitoring device and a deep cone thickener. Background Technology

[0002] The deep cone thickener is an essential piece of equipment in tailings backfilling operations. However, due to its working characteristics, measuring its material level is very difficult. The material level in the deep cone thickener is related to the final concentration of the material and the backfilling efficiency.

[0003] Currently, the measurement of material level in deep cone thickeners mainly relies on pressure sensors at the bottom of the thickener or various forms of counterweights. However, due to the complex internal working conditions of deep cone thickeners, relying solely on pressure sensors to calculate the material level or using counterweights to measure the material level is inaccurate and unrepresentative. Furthermore, deep cone thickeners often require pumping at the bottom; if the counterweight falls off, it could damage the pump, affecting production and endangering the lives and property of workers.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a deep cone thickener operating condition monitoring device and a deep cone thickener to solve the problems mentioned in the background art.

[0006] To achieve one of the above objectives, the present invention provides the following technical solution:

[0007] A deep cone thickener operating condition monitoring device includes a cylindrical shell, an information control module, and a power supply module. The information control module and the power supply module are disposed inside the cylindrical shell. A sand chamber, a water chamber, a turbidity sensor, and a pressure sensor are also disposed on the cylindrical shell.

[0008] Preferably, the sand silo and the water silo are located at the bottom of the cylindrical shell.

[0009] Preferably, the number of sand bins is two.

[0010] Preferably, the pressure sensor is located above the cylindrical housing.

[0011] Preferably, the turbidity sensor is located on the side of the cylindrical housing.

[0012] Preferably, the number of turbidity sensors is two.

[0013] Preferably, one of the turbidity sensors is located above the horizontal center line of the cylindrical housing, and the other of the turbidity sensors is located below the horizontal center line of the cylindrical housing.

[0014] To achieve the second objective mentioned above, the present invention provides the following technical solution:

[0015] A deep cone thickener includes a deep cone thickener operating condition monitoring device as described above.

[0016] Preferably, a dead zone monitoring device is fixed on the inner wall and the guide rod of the deep cone thickener. The dead zone monitoring device includes a glass shell, inside which a power module and an information control module are installed, and outside the glass shell, a turbidity sensor is installed.

[0017] Preferably, the number of turbidity sensors is two.

[0018] Compared with the prior art, the deep cone thickener condition monitoring device and deep cone thickener provided by the present invention have the following advantages:

[0019] 1. The present invention provides a deep cone thickener condition monitoring device and a deep cone thickener. The deep cone thickener condition monitoring device is in the shape of a short cylinder. When in use, it is placed in the deep cone thickener. By adjusting the weight of the monitoring device, buoyancy is used to make it float on the interface between the water and the dense phase layer, thereby achieving the purpose of measuring the material level in the deep cone thickener.

[0020] 2. The deep cone thickener condition monitoring device and the deep cone thickener provided by the present invention have two sand chambers and one water chamber below the deep cone thickener condition monitoring device. The weight of the device can be adjusted by adjusting the water chamber, thereby adjusting the suspension position; the sand chamber is used as a counterweight to enable the entire device to reach the designated position.

[0021] 3. The deep cone thickener operating condition monitoring device and the deep cone thickener provided by the present invention address the issue that due to the selection of the deep cone thickener or the design of the feed well, there are often dead zones at the edge of the deep cone thickener. Therefore, by installing dead zone monitoring devices on the inner wall of the deep cone thickener and the water guide rod respectively, and using turbidity sensors to calculate the concentration at the location, the production capacity of the deep cone thickener is improved.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] like Figure 1As shown in the figure, an embodiment of the present invention provides a deep cone thickener operating condition monitoring device, including a cylindrical shell 100, an information control module 200, and a power module 300. The information control module 200 and the power module 300 are disposed inside the cylindrical shell 100. A sand chamber 110, a water chamber 120, a turbidity sensor 400, and a pressure sensor 500 are also disposed on the cylindrical shell 100. The sand chamber 110 and the water chamber 120 are located at the bottom of the cylindrical shell 100, and there are two sand chambers 110. The pressure sensor 500 is located above the cylindrical shell 100. The turbidity sensor 400 is located on the side of the cylindrical shell 100, and there are two turbidity sensors 400. One of the turbidity sensors 400 is located above the horizontal center line of the cylindrical shell 100, and the other of the turbidity sensors 400 is located below the horizontal center line of the cylindrical shell 100.

[0040] In the above embodiments, the dense phase layer in the deep cone thickener is a nearly homogeneous system, meaning its density is a relatively fixed value, and this value remains constant throughout the production process. The deep cone thickener operates in three zones: a clarification zone, a transition zone, and a sedimentation zone. Given that the densities in the transition and sedimentation zones are known, this embodiment allows the thickener to suspend itself between the transition and sedimentation zones, automatically adjusting its height according to the material layer height, thereby enabling the measurement of the material layer height.

[0041] Specifically, the deep cone thickener condition monitoring device is cylindrical in shape and is placed inside the deep cone thickener during use. By adjusting the weight of the monitoring device, buoyancy is used to make it float on the interface between the water and dense phase layers, thereby measuring the material level in the deep cone thickener. The height of the material layer is calculated from the pressure measured by the pressure sensor 500. Two sand silos 110 and one water silo 120 are located below the deep cone thickener condition monitoring device. First, the sand silos 110 serve as counterweights; filling them with sand lowers the entire device to a designated position. Then, adjusting the water level in the water silo 120 adjusts the weight of the device, thus adjusting its suspension position. Specifically, water in the water silo 120 can be discharged through valve 121, ensuring that the weight of the deep cone thickener condition monitoring device is precisely suspended on the interface between the water and dense phase layers. The water discharge is initiated by the information control module 200 receiving a signal from the central control room.

[0042] Then, when the power supply of the deep cone thickener condition monitoring device is too low or the dense phase layer is submerged in the device (i.e., when the readings of the two turbidity sensors 400 are the same), the sealing covers 111 of the two sand chambers 110 will open, releasing the counterweight sand in the sand chambers 110, reducing the weight of the device, and causing the deep cone thickener condition monitoring device to float.

[0043] In one embodiment where the sand bin 110 is opened, the sand bin 110 is pushed open by a scissor-type lifting device 130 installed inside the deep cone thickener condition monitoring device. When the power supply is too low or the dense phase immersion device is submerged, the scissor-type lifting device 130 moves downward to push the sand in the sand bin 110 to open the sealing cover 111. To prevent the sealing cover 111 from falling into the deep cone thickener, the sealing cover 111 is connected to the bottom of the cylindrical housing 100 by a hinge 112.

[0044] In the above embodiment, the deep cone thickener condition monitoring device can float in the deep cone thickener for an extended period, enabling real-time monitoring of the material layer. All signals collected by the sensors are transmitted to the central control room via the information control module 200, providing better guidance for actual production on-site. Simultaneously, the deep cone thickener condition monitoring device can automatically float to prevent it from being buried under the material layer, avoiding potential safety hazards to subsequent processes. Furthermore, the sand in the sand bin 110 can be directly released into the deep cone thickener without affecting the overall system.

[0045] like Figure 2 As shown, another embodiment of the present invention provides a deep cone thickener, which includes a deep cone thickener operating condition monitoring device. The monitoring device includes a cylindrical housing 100, an information control module 200, and a power module 300. The information control module 200 and the power module 300 are disposed inside the cylindrical housing 100. A sand chamber 110, a water chamber 120, a turbidity sensor 400, and a pressure sensor 500 are also disposed on the cylindrical housing 100. The sand chamber 110 and the water chamber 120 are located at the bottom of the cylindrical housing 100, and there are two sand chambers 110. The pressure sensor 500 is located above the cylindrical housing 100. The turbidity sensor 400 is located on the side of the cylindrical housing 100, and there are two turbidity sensors 400. One of the turbidity sensors 400 is located above the horizontal center line of the cylindrical housing 100, and the other of the turbidity sensors 400 is located below the horizontal center line of the cylindrical housing 100.

[0046] Furthermore, in the above embodiments of the present invention, a dead zone monitoring device 600 is fixed on the inner wall and guide rod of the deep cone thickener. The dead zone monitoring device includes a glass housing 700, inside which a power module 300 and an information control module 200 are disposed, and on the outside of the glass housing 700 are two turbidity sensors 400.

[0047] Due to selection issues or feed well design problems, dead zones often exist at the edges of deep cone thickeners. Utilizing these dead zones can improve the production capacity of the deep cone thickener. Therefore, in this invention, dead zone monitoring devices 600 are installed on the inner wall of the deep cone thickener and on the guide rod. Turbidity sensors 400 are used to calculate the concentration at the specified location. Since these devices are fixed inside the deep cone thickener, their location is known.

[0048] In a preferred embodiment of the above embodiments, the glass housing 700 of the dead zone monitoring device is not made of a robust and pressure-resistant material, but rather of thin glass with an engraved texture. The glass housing 700 will shatter when subjected to sufficiently high pressure. Because the volume of this dead zone monitoring device is much larger than the suitable working particle size of the deep cone thickener underflow pump, if the device were to fall off and reach the discharge port, it would affect the operation of the underflow pump. Therefore, the glass housing 700 is treated to have a maximum pressure set for it. Once this pressure is exceeded, the glass housing 700 will shatter, and the internal device will disintegrate, thus protecting the underflow pump to the greatest extent possible.

[0049] In addition, since the inside of the deep cone thickener is filled with liquid for a long time, it is difficult to replenish the internal power of the dead zone monitoring device. Therefore, the dead zone monitoring device 600 is also equipped with a power generation device 800. The liquid inside the deep cone thickener flows under the action of the rake body, thereby driving the rotation of the power generation impeller 810 in the power generation device 800 to generate electricity for its own operation.

[0050] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
