Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a high liquid level alarm device for a slurry pump pool. Background Art

[0002] The slurry pump pool is a slurry container used to store the slurry generated by the upper operation during the mineral processing process. The slurry is transported to the lower operation through a pump. Due to the large amount of water vapor above the pump pool and the splashing of slurry, the use effect of liquid level monitoring equipment such as liquid level gauges and liquid level probes is not good. When the liquid level in the pump pool is high, the slurry overflows, causing metal loss and resulting in large economic losses. Therefore, in order to solve the above problems, we propose a slurry pump pool high liquid level alarm device. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a high liquid level alarm device for a slurry pump pool, which solves the technical problem that due to the influence of large water vapor and slurry splashing above the pump pool, the use of liquid level monitoring equipment such as liquid level gauges and liquid level probes is not effective. When the pump pool liquid level is high, the slurry overflows, causing metal loss and resulting in large economic losses.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A high liquid level alarm device for a slurry pump pool includes a pump pool and an alarm. An overflow drainage pipe is fixedly installed on the side end of the pump pool. A diversion pipe is fixedly connected to the upper part of the overflow drainage pipe. An open channel of a factory building is arranged below the diversion pipe. Mounting brackets are fixedly installed on both sides of the open channel of the factory building. Adjustment brackets are fixedly installed above the two mounting brackets. Infrared radiation switches are fixedly installed on the two adjustment brackets. Protective covers are provided on the outer sides of the two adjustment brackets. The alarm is electrically connected to the infrared radiation switch.

[0006] Preferably, the flow guide pipe is a DN25 or DN50 galvanized pipe, and the two infrared beam switches are located below the flow guide pipe. The infrared beam switches include an infrared pulse transmitter and an infrared pulse receiver decoder.

[0007] Preferably, both protective covers are symmetrically provided with perforations, the positions of the two perforations correspond to the positions of the infrared radiation switches, and the alarm is an audible and visual alarm.

[0008] The utility model has the following beneficial effects:

[0009] 1. When the pump pool is at a high liquid level and slurry appears in the overflow sewage pipe, the slurry is discharged along the diversion pipe, and the infrared radiation switch will be triggered, causing the alarm to sound. This allows the operator to know the liquid level of the pump pool in time and then increase the pump frequency appropriately. This real-time monitoring and alarm design has brought significant beneficial effects. It can effectively reduce the frequency of slurry pump pool overflow, minimize the waste of slurry and the loss of metal, which not only helps to save resources and reduce production costs, but also improves the economic benefits of the enterprise.

[0010] Second, through this natural diversion method, the slurry can smoothly flow along the diversion pipe into the upper part of the open channel of the plant, and then follow the open channel to the lower end operation. The beneficial effect of this design is that it realizes the orderly discharge and transfer of the slurry, avoids excessive accumulation of slurry in the pump pool and the possible overflow risk. It ensures that the slurry can flow according to the predetermined path, reduces the possibility of environmental pollution and production accidents caused by disorderly discharge, and at the same time, provides convenient conditions for subsequent processing and utilization, improving the efficiency and stability of the entire production process.

[0014] The embodiment of the present application provides a high liquid level alarm device for a slurry pump pool, which effectively solves the technical problem that due to the influence of large water vapor and slurry splashing above the pump pool, the use of liquid level monitoring equipment such as liquid level gauges and liquid level probes is not effective. When the pump pool liquid level is high, the slurry overflows, causing metal loss and resulting in large economic losses. Example

[0015] according to Figure 1 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the liquid level monitoring equipment such as liquid level gauges and liquid level probes are not effective due to the influence of large water vapor and slurry splashing above the pump pool. When the pump pool liquid level is high, the slurry overflows, causing metal loss and causing large economic losses. The overall idea is as follows:

[0016] In response to the problems existing in the prior art, the utility model provides a high liquid level alarm device for a slurry pump pool, comprising a pump pool 1 and an alarm 18. An overflow drain pipe 11 is fixedly installed on the side end of the pump pool 1, and a guide pipe 12 is fixedly connected to the top of the overflow drain pipe 11. A plant open channel 13 is provided below the guide pipe 12. When the slurry level in the pump pool 1 reaches the overflow drain pipe 11, the slurry will flow out naturally along the overflow drain pipe 11 and reach the top of the guide pipe 12. This process relies entirely on gravity and does not require additional power drive, thereby reducing energy consumption and operating costs. Mounting brackets 14 are fixedly installed on both sides of the plant open channel 13. The two mounting brackets 14 are fixedly installed on the two sides of the plant open channel 13. 4 are fixedly mounted with an adjustment bracket 15 above each of which an infrared radiation switch 16 is fixedly mounted. A protective cover 17 is provided on the outside of each of the adjustment brackets 15. An alarm 18 is electrically connected to the infrared radiation switch 16. The infrared radiation switch 16 is fixed on the adjustment bracket 15. By adjusting the adjustment bracket 15, the infrared radiation switch 16 is placed at the same horizontal height, and the infrared light of the infrared radiation switch 16 is ensured to be located at the lower center line of the guide pipe 12. When the pump pool 1 is at a high liquid level and slurry appears in the overflow sewage pipe 11, the slurry is discharged along the guide pipe 12, and the infrared radiation switch 16 will be triggered, thereby triggering the alarm 18 to sound an alarm.

[0017] The guide pipe 12 is a DN25 or DN50 galvanized pipe. The two infrared beam switches 16 are located below the guide pipe 12. The infrared beam switch 16 includes an infrared pulse transmitter and an infrared pulse receiving decoder. The two protective covers 17 are symmetrically provided with perforations, and the positions of the two perforations correspond to the positions of the infrared beam switches 16. The alarm 18 is an audible and visual alarm. In order to prevent the slurry from splashing onto the infrared beam switch 16 and affecting the accuracy of the equipment, a protective cover 17 is specially used to protect the infrared beam switch 16, and a φ50mm perforation is opened at the height of the infrared probe.

[0018] Working principle:

[0019] In the first step, when the slurry level in the pump pool 1 reaches the overflow drain pipe 11, the slurry will flow out naturally along the overflow drain pipe 11 and reach the top of the diversion pipe 12. This process relies entirely on gravity and does not require additional power drive, thereby reducing energy consumption and operating costs. Through this natural diversion method, the slurry can smoothly enter the open channel 13 of the factory building along the diversion pipe 12, and then enter the lower end operation along the open channel. The beneficial effect of this design is that it realizes the orderly discharge and transfer of the slurry, avoids excessive accumulation of the slurry in the pump pool 1 and the possible overflow risk. It ensures that the slurry can flow according to the predetermined path, reduces the possibility of environmental pollution and production accidents caused by disordered discharge, and at the same time, provides convenient conditions for subsequent processing and utilization, thereby improving the efficiency and stability of the entire production process.

[0020] In the second step, the infrared beam switch 16 is fixed to the adjustment bracket 15. By adjusting the adjustment bracket 15, the infrared beam switch 16 is placed at the same horizontal height and the infrared light of the infrared beam switch 16 is ensured to be located at the center line of the lower part of the diversion tube 12. In order to prevent the slurry from splashing onto the infrared beam switch 16 and affecting the accuracy of the equipment, a protective cover 17 is specially used to protect the infrared beam switch 16, and a φ50mm perforation is opened at the height of the infrared probe. When the pump pool 1 is at a high liquid level and slurry appears in the overflow sewage pipe 11, the slurry is discharged along the diversion tube 12, and the infrared beam switch 16 is triggered, thereby triggering the alarm 18 to sound an alarm. This allows the operator to promptly understand the liquid level of the pump pool 1 and then appropriately increase the pump frequency. This real-time monitoring and alarm design has brought significant beneficial effects. It can effectively reduce the frequency of slurry pump pool overflows, minimize slurry waste and metal loss to the greatest extent, which not only helps to save resources and reduce production costs, but also improves the economic benefits of the enterprise.

[0021] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
