Description

TECHNICAL FIELD

[0001] The application relates to the technical field of chemical safety protection, and particularly discloses a copper-nickel ore sulfuric acid tank safety early warning device. BACKGROUND

[0002] In the chemical production process such as copper-nickel ore hydrometallurgy, the sulfuric acid tank is a key reaction or storage device, and the stability of the internal gas pressure of the tank is directly related to the production safety, equipment integrity and process efficiency. Abnormal gas pressure in the tank, low pressure or overpressure operation, may cause tank deformation, sealing failure and even cause serious safety accidents such as leakage and spatter, and cause environmental pollution and personal injury. Therefore, real-time and accurate monitoring and alarm of the internal gas pressure of the sulfuric acid tank is an indispensable link to ensure the safe operation of chemical production.

[0003] At present, the traditional gas pressure monitoring scheme commonly used in the industry usually includes a gas pressure detector installed on the tank body, a central controller and an audible and visual alarm device. The working principle is that the probe of the gas pressure detector senses the pressure in the tank and converts it into an electrical signal; the signal is transmitted to the central controller through a cable; the control program preset in the controller processes and judges the received signal, and when the detected gas pressure value exceeds the preset safety threshold, the controller issues an instruction to drive the alarm device to act.

[0004] However, the signal needs to be transmitted from the detector to the independent controller through the line, and then triggered by the control program after logical judgment. The data transmission link is long and has many links. The hardware reliability of the controller, the stability of the software program and the integrity of the communication interface may all cause the entire monitoring system to malfunction, the alarm function to fail and a major safety blind spot to be formed.

[0005] In addition, the acid mist volatilized in the sulfuric acid tank is easy to condense and crystallize on the surface of the sensing probe of the gas pressure detector. These attached acid mist crystals can block the pressure tapping hole, corrode the sensitive diaphragm or change the sensing characteristics of the probe, causing distortion of the pressure sensing, slow response or zero drift, which may cause false alarms or more dangerous missed alarms, so that the monitoring data loses reference value.

[0006] At the same time, in order to ensure accuracy, the probe needs to be frequently disassembled, cleaned or calibrated, which not only increases the maintenance workload and cost, but also increases the safety risk of equipment operation during maintenance operation when the monitoring system is in an abnormal working state.

[0007] It can be seen that the current copper-nickel ore sulfuric acid tank safety early warning device has the problems of complex data transmission, probe susceptible to environmental interference and difficult maintenance. Therefore, the present application provides a copper-nickel ore sulfuric acid tank safety early warning device to solve the above problems. SUMMARY

[0008] The present application aims to solve the problems of complex data transmission, easy environmental interference of the probe and difficult maintenance of the conventional copper-nickel ore sulfuric acid tank safety warning device.

[0009] In order to achieve the above-mentioned purpose, the basic scheme of the present application provides a copper-nickel ore sulfuric acid tank safety warning device, comprising: A communication pipe is in communication with the inside of the sulfuric acid tank. An adjusting rod is provided with a gas pressure piston in sliding and sealing connection with the communication pipe. An alarm assembly includes a power supply, an alarm connected with the power supply, and an electric connection piece arranged between the alarm and the power supply, and the adjusting rod is provided with a conductive ring capable of contacting the electric connection piece to energize the alarm.

[0010] The principle and effect of the basic scheme are: Compared with the prior art, the communication pipe is in communication with the inside of the sulfuric acid tank, the internal gas pressure of the communication pipe is the same as the internal gas pressure of the sulfuric acid tank, and the gas pressure piston is driven to move when the internal gas pressure of the sulfuric acid tank increases or decreases, thereby driving the adjusting rod to move, and the conductive ring directly connects the electric connection piece when the set stroke is exceeded, thereby connecting the power supply and the alarm through the electric connection piece to alarm, replacing the complex signal transmission process of the conventional device, and directly issuing an alarm signal, effectively solving the problems of complex data transmission and poor stability of the copper-nickel ore sulfuric acid tank safety warning device.

[0011] Further, the alarm and the electric connection piece are both two groups, and when the pressure in the sulfuric acid tank is lower than the minimum safety value or higher than the maximum safety value, the conductive ring is in electrical contact with the two electric connection pieces respectively, so that the corresponding alarm is energized. Thus, corresponding alarm signals are respectively issued when the gas pressure in the sulfuric acid tank is too high or too low.

[0012] Further, it further comprises a anti-blocking mechanism, the anti-blocking mechanism drives the gas pressure piston to reciprocate in the communication pipe, and the bottom of the communication pipe is communicated with a deslagging pipe. Thus, the acid mist volatilized in the sulfuric acid tank is prevented from condensing and crystallizing at the cooperation place of the gas pressure piston and the communication pipe, thereby avoiding the influence of the condensed matter on the normal position movement of the gas pressure piston, improving the accuracy of safety warning, and reducing the frequency of manual maintenance.

[0013] Further, it further comprises a blocking mechanism capable of blocking the communication pipe from the sulfuric acid tank and a supply mechanism capable of supplying a neutralizing agent to the communication pipe. The blocking mechanism comprises a fixed sleeve arranged on the side wall of the communication pipe, a blocking piston in sliding connection with the inner wall of the fixed sleeve, and a control assembly for controlling the movement of the blocking piston, and the blocking piston is provided with a gas guide through hole capable of guiding the communication pipe to the sulfuric acid tank. The supply mechanism comprises a liquid supply branch pipe communicated with the communicating pipe and a liquid supply main pipe communicated with the side wall of the liquid supply branch pipe, and the partition piston is connected with a first valve core slidingly and sealingly adjusted with the liquid supply branch pipe through a first support, and the first valve core is provided with a liquid injection channel for connecting the liquid supply pipe with the liquid supply branch pipe.

[0014] The partition mechanism and the supply mechanism can partition the communicating pipe from the inside of the sulfuric acid tank and supply the neutralizing agent when the anti-blocking mechanism is cleaning the communicating pipe, so as to effectively prevent the sulfuric acid liquid stored in the sulfuric acid tank from being polluted during the cleaning process.

[0015] Further, the control assembly comprises an electromagnet arranged in the fixed sleeve, an armature arranged at the bottom of the partition piston and magnetically matched with the electromagnet, and a first spring arranged between the electromagnet and the armature, so as to adjust the position of the partition piston. Further, the residue discharge pipe comprises a residue discharge branch pipe communicated with the bottom of the communicating pipe and a residue discharge main pipe communicated with the side wall of the residue discharge branch pipe, and the bottom of the partition piston is connected with a second valve core slidingly connected with the inner wall of the residue discharge branch pipe and capable of blocking the residue discharge main pipe through a second support, so as to control the communication or disconnection of the residue discharge branch pipe with the residue discharge main pipe, thereby making the residue discharge branch pipe communicated with the residue discharge main pipe when the anti-blocking mechanism is cleaning the communicating pipe, and disconnecting the residue discharge branch pipe from the residue discharge main pipe after the cleaning is completed, so as to maintain the closed environment of the communicating pipe.

[0016] Further, the adjusting rod comprises a first rod body connected with the gas pressure piston, a second rod body connected with the conductive ring, and a connecting frame arranged between the first rod body and the second rod body, and the two sides of the connecting rod are respectively provided with a push block, the anti-blocking mechanism comprises a power member, a rocker arm driven to rotate by the power member, and a push rod arranged at the end of the rocker arm, and the push rod is matched with the push block. The power member drives the rocker arm to rotate, and the push rod on the rocker arm intermittently pushes the push block on the connecting frame to drive the connecting frame to move reciprocatingly, thereby driving the adjusting rod and the gas pressure piston to move reciprocatingly as a whole, and further cleaning the inner wall of the communicating pipe.

[0017] Further, the push rod is provided with a push rod shaft slidingly connected with the rocker arm, and a second spring is arranged between the push rod shaft and the rocker arm. Through this arrangement, the push rod is extended to be matched with the push block under the action of centrifugal force during high-speed rotation of the push rod, and the push rod is retracted under the action of the second spring when the push rod and the rocker arm stop rotating, so that the push rod is out of contact with the push block, thereby avoiding the influence of the push block on the normal position movement of the gas pressure piston.

[0018] Furthermore, the anti-clogging mechanism also includes a rotating shaft driven by a power component. The rotating shaft is rotatably connected to the first rod and the pneumatic piston, and a cleaning shaft is splined to the rotating shaft. The cleaning shaft is rotatably connected to the pneumatic piston, and one end of the cleaning shaft extends out of the pneumatic piston and is equipped with a brush that moves along the inner wall of the connecting pipe. By setting up the cleaning shaft, the rotating shaft drives the cleaning shaft to rotate, and the pneumatic piston drives the cleaning shaft to move. The brush at the end of the cleaning shaft cooperates with the inner wall of the connecting pipe, improving the cleaning effect on the inside of the connecting pipe.

[0019] Furthermore, the rocker arm and the rotating shaft are connected by a bevel gear pair, and a sleeve is rotatably connected to the rocker arm shaft. The side wall of the sleeve is provided with a connecting shaft that extends into and rotatably connects to the rotating shaft. The sleeve, connecting shaft, and rotating shaft cooperate to limit the movement of the rotating shaft. Attached Figure Description

[0024] A safety early warning device for a copper-nickel ore sulfuric acid tank, implementing, for example... Figure 1 and Figure 2 As shown: The warning device 3 includes a connecting pipe 4 connected to the sulfuric acid tank 1, a drive box 5 located at the end of the connecting pipe 4, and an alarm mounting box 6 located on the side of the drive box 5 away from the connecting pipe 4. The connecting pipe 4 is located on the side wall of the breather 2 pipe at the top of the sulfuric acid tank 1 and is installed in a downward inclined manner. An adjusting rod is provided through the connecting pipe 4, the drive box 5, and the alarm mounting box 6.

[0025] like Figure 3 As shown, a disconnection mechanism and a liquid supply mechanism are respectively provided on the connecting pipe 4. The disconnection mechanism is used to control whether or not the connection is made with the sulfuric acid tank 1, and the liquid supply mechanism is used to control whether or not a neutralizing agent is supplied to the connecting pipe 4. The disconnection mechanism includes a fixed sleeve 7 provided on the side wall of the connecting pipe 4, a disconnection piston 8 slidably connected to the inner wall of the fixed sleeve 7, and a control assembly for controlling the movement of the disconnection piston 8. The disconnection piston 8 is provided with a gas guide hole 15 that can conduct the connecting pipe 4 to the sulfuric acid tank 1. The control assembly includes an electromagnet 16 provided in the fixed sleeve 7, an armature 17 provided at the bottom of the disconnection piston 8 and magnetically engaged with the electromagnet 16, and a first spring 18 provided between the electromagnet 16 and the armature 17.

[0026] When the electromagnet 16 is not energized, the armature 17 is mainly subjected to the elastic force of the first spring 18, and the two ends of the gas guide hole 15 connect the connecting pipe 4, which is connected to the inside of the sulfuric acid tank 1. When the electromagnet 16 is energized, the armature 17 is moved down by the combined magnetic force of the first spring 18 and the electromagnet 16, so that the gas guide hole 15 is blocked by the inner wall of the fixed sleeve 7, and the connecting pipe 4 is blocked by the isolation piston 8.

[0027] The supply mechanism includes a supply branch pipe 12 connected to the connecting pipe 4 and a supply main pipe 9 connected to the side wall of the supply branch pipe 12. Correspondingly, the bottom of the connecting pipe 4 is also connected to a slag discharge pipe, which includes a slag discharge branch pipe 13 connected to the bottom of the connecting pipe 4 and a slag discharge main pipe 10 connected to the side wall of the slag discharge branch pipe 13. When the supply main pipe 9 is connected to the supply branch pipe 12, the neutralizing agent stored externally is introduced into the connecting pipe 4, and the slag discharge main pipe 10 is connected to the slag discharge branch pipe 13 to discharge the neutralizing agent from the reaction. When the supply main pipe 9 is not connected to the supply branch pipe 12 and the slag discharge main pipe 10 is not connected to the slag discharge branch pipe 13, the connecting pipe 4 is isolated from the outside and is in a relatively closed environment.

[0028] The top of the isolation piston 8 is connected to a first valve core 11 that slides and seals with the liquid supply branch pipe 12 via a first bracket 1401. The first valve core 11 is provided with an injection channel 19 that can connect the liquid supply pipe and the liquid supply branch pipe 12. One end of the injection channel 19 faces the side wall of the main liquid supply pipe 9 and can be sealed by the inner wall of the liquid supply branch pipe 12. The other end of the injection channel 19 faces the first valve core 11 and is located inside the liquid supply branch pipe 12. The bottom of the isolation piston 8 is connected to a second valve core 20 that slides with the inner wall of the slag discharge branch pipe 13 via a second bracket 1402 and can block the slag discharge main pipe 10. Correspondingly, the side wall of the fixed sleeve 7 is provided with a sliding groove that allows the second bracket 1402 to slide.

[0029] When the electromagnet 16 is not energized, the armature 17 is mainly subjected to the elastic force of the first spring 18. The first valve core 11 and the second valve core 20 are both in a higher position. The end of the injection channel 19 is sealed by the inner wall of the supply branch pipe 12, and the first valve core 11 blocks the end of the main supply pipe 9. At the same time, the second valve core 20 blocks the slag discharge pipe 10. The connecting pipe 4 is isolated from the outside and is in a relatively closed environment. When the electromagnet 16 is energized, the armature 17 moves down under the combined action of the magnetic force of the first spring 18 and the electromagnet 16. The first valve core 11 and the second valve core 20 are both in a lower position. The two ends of the injection channel 19 connect the main supply pipe 9 and the supply branch pipe 12 respectively. At the same time, the second valve core 20 releases the blockage of the slag discharge pipe 10. The connecting pipe 4 is connected to the main supply pipe 9 and the slag discharge pipe 10. The main supply pipe 9 introduces the neutralizing agent stored outside into the connecting pipe 4, and the slag discharge branch pipe 13 connects to discharge the neutralizing agent of the reaction.

[0030] like Figure 4As shown, the drive box 5 is equipped with an anti-clogging mechanism to drive the pneumatic piston 31 to reciprocate within the connecting pipe 4, reducing the condensation and crystallization of acid mist volatilized from the sulfuric acid tank 1 at the interface between the pneumatic piston 31 and the connecting pipe 4. The anti-clogging mechanism includes a servo motor located outside the drive box 5, a rocker arm 23 shaft rotatably connected within the drive box 5, a drive bevel gear 21 and the rocker arm 23 respectively mounted on the rocker arm 23 shaft, wherein, as shown... Figure 5 As shown, the rocker arm 23 has a sliding cavity, and a lever shaft 24 is slidably connected to the sliding cavity. One end of the lever shaft 24 is slidably connected to the sliding cavity and is provided with a retaining ring 33. The other end of the lever shaft 24 extends out of the sliding cavity and is provided with a lever 25. A second spring 34 is provided between the retaining ring 33 and the sliding cavity. When the servo motor is activated, the rocker arm 23 shaft, rocker arm 23, lever shaft 24, and lever 25 rotate as a whole. During high-speed rotation, the lever 25 extends radially outward under the action of centrifugal force; when the lever 25 and rocker arm 23 stop rotating, the lever 25 is retracted by the pulling force of the second spring 34.

[0031] The adjusting rod includes a connecting frame 26, a first rod body 2801 located at one end of the connecting frame 26, and a second rod body 2802 located at the other end of the connecting frame 26. The connecting frame 26 is a U-shaped frame, and a top lever block 2701 and two bottom lever blocks 2702 are respectively provided at the top and bottom of the frame. The top lever block 2701 is located in the middle of the U-shaped frame, and the bottom lever blocks 2702 are located at both ends of the U-shaped frame, so that at least one lever block can cooperate with the lever 25 during the rotation of the lever 25.

[0032] This configuration allows the lever 25 to extend radially outward during high-speed rotation and engage sequentially with the top lever 2701 and the bottom lever 2702 to drive the connecting frame 26 and the adjusting rod to reciprocate as a whole. At the same time, when the lever 25 and the rocker arm 23 stop rotating, the lever 25 disengages from the lever, preventing the lever 25 from affecting the normal position movement of the pneumatic piston 31 through the engagement of the lever and the lever.

[0033] The end of the first rod 2801 extends into the connecting pipe 4 and is provided with a pneumatic piston 31 that is slidably and sealingly connected to the inner wall of the connecting pipe 4. The end of the second rod 2802 extends into the alarm mounting box 6 and is provided with a conductive ring 29. Correspondingly, the alarm mounting box 6 is provided with two sets of electrical connecting pieces 30, which are located at the left and right extreme positions of the second rod 2802 respectively. The alarm mounting box 6 is provided with a power supply and two alarms connected by the two sets of electrical connecting pieces 30 respectively. In one set of electrical connecting pieces 30, there are two connecting pieces symmetrically located on both sides of the traveling position of the conductive ring 29. When the conductive ring 29 moves between the connecting pieces, it electrically connects the corresponding set of connecting pieces, that is, it powers on the corresponding alarm.

[0034] like Figure 6 and Figure 7As shown, the driving bevel gear 21 meshes with the driven bevel gear 22. The drive box 5 is provided with a rotating shaft connected to the driven bevel gear 22. The rotating shaft includes a first shaft body 37 and a second shaft body 38 connected to each other. The first shaft body 37 is rotatably connected to a connecting shaft 36. One end of the connecting shaft 36 is located inside the first shaft body 37 and is provided with a retaining ring. The other end of the connecting shaft 36 extends out of the first shaft body 37 and the driven bevel gear 22 and is provided with a sleeve 35 sleeved on the rocker arm 23 shaft. The sleeve 35 is rotatably connected to the rocker arm 23 shaft. The outer wall of the second shaft body 38 is slidably connected to the inside of the pneumatic piston 31. The inner wall of the second shaft body 38 is splined connected to a cleaning shaft 39. The shaft of the cleaning shaft 39 is provided with a connecting disc rotatably connected to the inside of the pneumatic piston 31. The end of the cleaning shaft 39 extends out of the pneumatic piston 31 and is provided with a brush body 32 that brushes along the inner wall of the connecting pipe 4.

[0035] In the safety warning process, the connecting pipe 4 is connected to the inside of the sulfuric acid tank 1. The air pressure inside the connecting pipe 4 is the same as the air pressure inside the sulfuric acid tank 1. When the air pressure inside the sulfuric acid tank 1 rises or falls, it drives the air pressure piston 31 to move, which in turn drives the adjusting rod to move. When the set stroke is exceeded, the conductive ring 29 directly connects the electrical connecting piece 30, which in turn connects the power supply to the alarm to trigger an alarm. This replaces the traditional complex signal transmission process and can directly issue an alarm signal, effectively solving the problems of complex data transmission and poor stability in the safety warning device 3 for copper-nickel ore sulfuric acid tank 1.

[0036] Furthermore, this invention can also directly clean the condensed crystals on the inner wall of the connecting pipe 4, as follows: First, the electromagnet 16 is energized, and the armature 17 moves downward under the combined magnetic force of the first spring 18 and the electromagnet 16, causing the air passage 15 to be blocked by the inner wall of the fixed sleeve 7, and the connecting pipe 4 to be blocked by the isolation piston 8. At the same time, the first valve core 11 and the second valve core 20 are both in a lower position, and the two ends of the liquid injection channel 19 are respectively connected to the main liquid supply pipe 9 and the branch liquid supply pipe 12. At the same time, the second valve core 20 releases the blockage of the slag discharge main pipe 10, and the connecting pipe 4 is connected to the main liquid supply pipe 9 and the slag discharge main pipe 10. The main liquid supply pipe 9 introduces the externally stored neutralizing agent into the connecting pipe 4, and the slag discharge branch pipe 13 is connected to discharge the neutralizing agent of the reaction.

[0037] Secondly, the servo motor is activated. The servo motor drives the rocker arm 23 and the active bevel gear 21 to rotate via the rocker arm 23 shaft. The rocker arm 23, the lever shaft 24, and the lever 25 rotate as a whole. During the high-speed rotation, the lever 25 extends radially outward under the action of centrifugal force, and cooperates with the top lever block 2701 and the bottom lever block 2702 in sequence to drive the connecting frame 26 and the adjusting rod to reciprocate as a whole. The pneumatic piston 31 is used to clean the inner wall of the connecting pipe 4. At the same time, the active bevel gear 21 drives the driven bevel gear 22 to rotate, which in turn drives the rotating shaft and the cleaning shaft 39 to rotate. The pneumatic piston 31 drives the cleaning shaft 39 to move. The brush body 32 at the end of the cleaning shaft 39 cooperates with the inner wall of the connecting pipe 4 to improve the cleaning effect inside the connecting pipe 4.

[0038] Furthermore, during this process, the adjusting rod moves back and forth, causing the conductive ring 29 on it to contact the two sets of electrical connection pieces 30 in sequence, thereby issuing an alarm signal. Operators can determine whether the warning device 3 is in normal condition based on whether an alarm signal is issued.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
