Description
Technical Field
[0001] The invention relates to the technical field of dust explosion venting and isolation, and in particular to a hydraulic explosion venting and isolation device and a working method. Background Art
[0002] Dust explosion is a byproduct of modern industrial production. With the increasing integration of industrial production, the number and volume of powder production processes are increasing. In recent years, dust explosion accidents have occurred frequently, so more and more attention has been paid to the prevention and hidden danger management of dust explosions. Among them, the use of explosion venting and flameproof technology to solve the explosion safety hazard of dust collector equipment is one of the main technical means on the market.
[0003] At present, it is difficult to control the isolation of explosion hazards when using traditional explosion venting discs in the operation process of enterprises. That is, although explosion venting discs are used, the pressure wave and flame generated by the explosion still have the possibility of propagating along the pipeline to the equipment, factory buildings or workshops and causing secondary explosions. On the other hand, after the explosion venting disc, due to factors such as excessive equipment temperature and pressure, there is a risk of dust re-entering and causing secondary explosions, and if there are no relevant measures around, the explosion venting process will also pollute the environment. Therefore, it is necessary to design an explosion venting isolation device that responds quickly, is low-cost, does not consume electricity, is safe and reliable, can solve the explosion safety hazards of dust collector equipment, is easy to block the secondary hazards of deflagration or explosion shock waves, and reduces environmental pollution, while being simple in design, reusable, and easy to market.
[0004] CN221402738U discloses a flameless discharge device for an explosive dust environment, including a transport pipeline, a flameproof device is fixedly installed on the right side of the transport pipeline, a surrounding body is fixedly installed on the right side of the flameproof device, an explosion relief device is fixedly installed on the right side of the surrounding body, and a discharge pipeline is fixedly installed below the surrounding body. When in use, the transport pipeline is installed on the equipment pipeline, and smoke is transported through the transport pipeline, enters the surrounding body through the barrier device, and enters the discharge pipeline for discharge. When the pressure in the surrounding body is too large to cause combustion and explosion, the control center issues an instruction to rotate the rotating shaft, and then rotates the barrier plate to fit the connecting closure block, so as to achieve the effect of blocking, and at the same time, the explosion relief piece is opened for explosion relief, and when the high-temperature explosive gas reaches the flame-blocking net for flame extinguishing, it is discharged without flame. However, this flameless discharge device for an explosive dust environment inevitably uses electrical components (such as a control center), and under the condition of dust explosion, electric sparks may be generated to cause combustion and explosion, which poses a safety hazard. Therefore, in the process of setting the explosion relief isolation device, the use of electrical components should be avoided as much as possible. In addition, the device has a complex structure and is not easy to maintain. Summary of the invention
[0005] In view of the problems in the above-mentioned prior art, the present invention proposes a hydraulic explosion-proofing isolation device and a working method, and provides an explosion-proofing isolation device which is quick in response, low in cost, power-saving, safe and reliable, and can solve the potential safety hazards of explosions in dust collector equipment, easily block the secondary hazards of deflagration or explosion shock waves, and reduce environmental pollution. The device has a simple structure, can be mass-produced, can be reused, is conducive to promotion, and can effectively solve the problems in the background technology.
[0006] In order to achieve the above object, the present invention has the following technical solutions:
[0007] The first object of the present invention is to provide a hydraulic explosion-proof isolation device, which includes a dust duct, a pressure relief partition, a blocking partition, a rotating shaft assembly, a counterweight assembly, a blocking partition fixing component, a pressure relief channel, and a fire extinguishing buffer; the dust duct is connected to the pressure relief channel; the connection between the dust duct and the pressure relief channel is connected with a rotating shaft assembly; the pressure relief partition and the blocking partition are connected through a rotating shaft assembly, and the rotating shaft assembly is used to realize the rotation of the pressure relief partition and the blocking partition; the counterweight assembly is connected to the rotating shaft assembly, and the counterweight assembly is used to counterweight so that the pressure relief partition is in a closed state and the blocking partition is in an open state; the blocking partition fixing component is connected to the dust duct, and the blocking partition fixing component is raised relative to the inner wall of the dust duct, and the blocking partition fixing component is used to limit the blocking partition when combustion and explosion occur in the dust duct to avoid further rotation; the pressure relief channel is connected to the fire extinguishing buffer.
[0008] Furthermore, the pressure relief channel comprises a dust duct pressure relief port; the dust duct pressure relief port is located at one end of the pressure relief channel close to the dust duct.
[0009] Furthermore, one end of the pressure relief channel away from the dust pipe is connected to a fire extinguishing buffer.
[0010] Furthermore, the hydraulic explosion relief isolation device also includes a water reservoir and a drain outlet; the water reservoir is filled with a fire extinguishing buffer solution; and the bottom end of the water reservoir is provided with a drain outlet.
[0011] Furthermore, the shaft assembly includes a partition handle shaft and a shaft fixing component; the partition handle shaft is respectively connected to the pressure relief partition and the blocking partition; a shaft fixing component is provided at the connection between the dust duct and the pressure relief channel; the partition handle shaft is connected to the shaft fixing component.
[0012] Furthermore, the counterweight assembly includes a rotating handle and a counterweight component; one end of the partition handle shaft is connected to the rotating handle; the counterweight component is connected to one end of the rotating handle, and physically acts as a counterweight through its own weight to prevent the blocking partition from tilting up due to the weight of the pressure relief partition when the dust duct is in a negative pressure or normal pressure state.
[0013] Furthermore, the partition handle shaft is respectively fixedly connected to the pressure relief partition and the blocking partition, the partition handle shaft is fixedly connected to the rotating handle, and the partition handle shaft is rotatably connected to the shaft fixing component.
[0014] Furthermore, the pressure relief baffle and the blocking baffle are in the same plane with an angle of 180°, and the area of the blocking baffle is smaller than that of the pressure relief baffle. During an explosion, the pressure relief baffle has a relatively large pressure area and is easily pushed by the pressure generated by the explosion to rotate and relieve pressure.
[0015] Furthermore, the rotating handle and the weight component are all in the same plane as the pressure relief partition and the blocking partition, and are close to the blocking partition.
[0016] Furthermore, the dust duct and the pressure relief channel are perpendicular to each other; the pressure relief channel is vertically arranged; and the dust duct is horizontally arranged.
[0017] Furthermore, the top surface of the fire extinguishing buffer solution in the water reservoir is higher than the bottom of the pressure relief channel.
[0018] Furthermore, the fire extinguishing buffer may be, but is not limited to, one of water and low-concentration soap water.
[0019] Furthermore, when the rotating handle is in a horizontal position, the pressure relief partition and the blocking partition are both in a horizontal position, that is, the blocking partition is in an open state, and the pressure relief partition is in a closed state.
[0020] Furthermore, when the rotating handle is in a vertical position, the pressure relief partition and the blocking partition are both in a vertical position, and the pressure relief partition is below the blocking partition, that is, the blocking partition is in a closed state and the pressure relief partition is in an open state.
[0021] A second object of the present invention is to provide an application method of a hydraulic explosion relief isolation device, comprising the following steps:
[0022] When the dust duct is under negative pressure or normal pressure, the pressure relief partition and the blocking partition are in a horizontal state, that is, the blocking partition is in an open state and the pressure relief partition is in a closed state;
[0023] When an explosion occurs in the dust duct, since the area of the pressure relief partition is larger than the area of the blocking partition, the air pressure in the dust duct can rotate the pressure relief partition and the blocking partition by 90 degrees, so that the blocking partition is rotated to a closed state, thereby isolating the explosion flame and the explosion shock wave in the dust duct. At the same time, the blocking partition fixing component can limit the blocking partition, reducing the possibility of damage to the blocking partition due to excessive rotation angle. On the other hand, the pressure relief partition will rotate to an open state, so that the explosion flame and the generated pressure are discharged from the pressure relief port of the dust duct. The fire extinguishing buffer can not only play a buffering role, but also play a fire extinguishing role. In addition, the fire extinguishing buffer can absorb harmful substances such as dust brought by the explosion, thereby reducing the possibility of harm to the environmental pollution.
[0024] After the explosion, as the pressure in the dust duct returns to normal, the pressure relief baffle and the blocking baffle rotate 90° under the gravity of the counterweight component and return to their original positions.
[0025] Furthermore, the hydraulic explosion relief isolation device specifically adopts the following steps during operation:
[0026] (1) First, confirm whether there is enough fire extinguishing buffer in the water reservoir and the height of the fire extinguishing buffer is higher than the bottom of the pressure relief channel;
[0027] (2) Secondly, confirm whether the counterweight component makes the rotating handle in a horizontal position, that is, the blocking baffle is in an open state and the pressure relief baffle is in a closed state;
[0028] (3) Then, after the dust collector equipment is turned on, confirm whether the liquid level of the fire extinguishing buffer in the water reservoir has dropped slightly, that is, to ensure that the pressure relief baffle is in a closed but not completely sealed state;
[0029] (4) If an explosion occurs in the dust duct, the air pressure in the dust duct will cause the pressure relief baffle and the blocking baffle to rotate 90 degrees;
[0030] (5) After the blocking partition is closed, the combustion flame and explosion shock wave in the dust removal duct are blocked, and the blocking partition fixing component can limit the blocking partition to achieve a relative equilibrium state;
[0031] (6) After the pressure relief baffle is opened, the explosion flame and the pressure generated are released from the dust pipe pressure relief port. The fire extinguishing buffer has a buffering effect on the explosion flame and the explosion shock wave, and can extinguish the explosion flame and absorb the dust and other harmful substances brought by the explosion;
[0032] (7) After the explosion is over, the pressure in the dust duct returns to normal, and the pressure relief baffle and the blocking baffle rotate 90° under the gravity of the counterweight component and return to their original positions;
[0033] (8) According to the actual situation of the explosion, check the status of the device and the fire extinguishing buffer solution. After draining the liquid through the drain, clean the water tank and then refill the fire extinguishing buffer solution.
[0034] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:
[0035] 1) The hydraulic explosion relief isolation device of the present invention has a simple structure, low cost, safe use, and easy maintenance. It can solve the explosion safety hazard problem of the dust pipe of the dust collector equipment by adopting explosion relief and flameproof technology.
[0036] 2) The hydraulic explosion relief isolation device of the present invention has a structure that has the effect of physically balancing weights through counterweight components. When the dust duct is in a negative pressure or normal pressure state, the pressure relief partition and the blocking partition are in a horizontal state, that is, the blocking partition is in an open state and the pressure relief partition is in a closed state.
[0037] 3) The hydraulic explosion relief isolation device of the present invention has a structure in which when an explosion occurs in the pipeline, since the area of the pressure relief baffle is larger than the area of the blocking baffle, the air pressure in the pipeline can rotate the pressure relief baffle and the blocking baffle 90°, so that the blocking baffle is rotated to a closed state, thereby isolating the explosion flame and the explosion shock wave in the dust removal pipeline. At the same time, the blocking baffle fixing component can limit the blocking baffle, reducing the possibility of damage due to excessive rotation angle. On the other hand, the pressure relief baffle will rotate to an open state, so that the explosion flame and the pressure generated will be discharged from the dust pipeline pressure relief port. The fire extinguishing buffer can not only play a buffering role, but also play a fire extinguishing role. In addition, the fire extinguishing buffer can absorb harmful substances such as dust caused by the explosion, reducing the possibility of harm to environmental pollution.
[0038] 4) The hydraulic explosion relief isolation device of the present invention does not use electrical components such as sensors and drive components, and fully utilizes the physical properties of the equipment components and environmental conditions. Therefore, it can greatly reduce the possibility of electric sparks and avoid the safety hazard of explosion caused by electric sparks generated during the operation of the device.
[0039] In summary, the hydraulic explosion relief isolation device of the present application has a simple structure, can be reused, is easy to maintain, and can be widely used in the field of explosion safety technology to address explosion safety hazards in dust ducts of dust collector equipment.
