[0001] This utility model belongs to the technical field of industrial dust removal equipment, specifically relating to a heavy dust removal discharge port ash unloading device. Background Technology
[0002] In industrial production processes, such as steel, cement, and chemical industries, a large amount of dust is generated, requiring the use of dust removal equipment for collection and treatment. The dust removal discharge port is a crucial component of this equipment, used to discharge the collected dust. Simultaneously, the dust removal ash discharge valve is a key device for ash discharge, air supply, and material feeding in dust removal systems. It can be used in material collection systems as a dust removal ash discharge valve for silos. This dust removal ash discharge valve is the most advanced unloading device in China and is commonly used in dust removal systems as a vital component. It is particularly suitable for dust and small particulate materials and is highly favored in engineering projects across industries such as environmental protection, metallurgy, chemicals, grain, cement, road construction, and drying equipment.
[0003] Traditional ash discharge devices for heavy dust collectors mostly use manual or simple mechanical control methods, which have the following problems: low degree of automation, cumbersome manual operation, and high labor intensity; untimely ash discharge, which easily causes dust accumulation and affects dust removal efficiency; poor sealing, which easily causes dust leakage and pollutes the environment. Therefore, a new ash discharge device for heavy dust collectors is proposed to solve the above problems. Utility Model Content

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0023] In this embodiment, see Figure 1-3 A heavy dust removal discharge device includes a heavy dust removal box 1, a heavy dust removal discharge port 2 at the bottom of the heavy dust removal box 1, a first sealing block 3 at the bottom of the heavy dust removal discharge port 2, an installation box 4 at the bottom of the heavy dust removal discharge port 2, an ash discharge valve 5 with both ends penetrating inside the installation box 4, the ash discharge valve 5 being used to control the discharge of dust, an alarm 6 being provided on the outside of the heavy dust removal box 1, a feed port 8 being provided on the outside of the heavy dust removal box 1, a second sealing block 9 being provided on the top of the feed port 8, and a level gauge 10 with one end penetrating and extending into the inside of the heavy dust removal box 1 being provided on the outside of the second sealing block 9, the level gauge 10 being able to detect the accumulation height of dust inside the heavy dust removal box 1.
[0024] It should be noted that the external part of the heavy dust removal feeding box 1 is equipped with a controller 7, and the level gauge 10 is set at a fixed height inside the heavy dust removal feeding box 1. When the dust inside the heavy dust removal feeding box 1 exceeds a certain height of the level gauge 10, the level gauge 10 will transmit a signal to the controller 7, which will facilitate the detection of dust.
[0025] Technical benefits: By installing a level gauge 10, the height of dust accumulation inside the heavy dust removal discharge box 1 is monitored in real time, and the controller 7 can automatically control the opening and closing of the ash discharge valve 5. No manual operation is required, reducing labor intensity, further improving the automation level of the heavy dust removal discharge equipment, saving labor, and bringing great convenience to the staff.
[0026] Optionally, the ash discharge valve 5 is fixedly installed through the mounting box 4. The ash discharge valve 5 is connected to the bottom of the heavy removal discharge port 2, which serves to install the ash discharge valve 5, thereby making the ash discharge valve 5 more stable during use and facilitating the control of ash discharge.
[0027] Technical effect: When the dust inside the heavy dust removal discharge box 1 accumulates to a certain height, the ash discharge valve 5 is automatically opened to discharge the dust, which further avoids the accumulation of dust inside the heavy dust removal discharge box 1, thereby avoiding the decrease in dust removal efficiency caused by dust accumulation.
[0028] Optionally, the ash discharge valve 5 is a pneumatic butterfly valve or an electric butterfly valve. The pneumatic butterfly valve uses compressed air to push the cylinder, which drives the valve plate to rotate. At the same time, the motor drives the valve stem to rotate through the gearbox. The pneumatic butterfly valve can be opened and closed quickly, while the electric butterfly valve can be adjusted with high precision. Both can quickly discharge the dust inside the heavy dust removal box 1.
[0029] It should be added that pneumatic butterfly valves require a pneumatic positioner and position sensor to be used, and a double-acting cylinder design is needed to prevent jamming; while electric butterfly valves require a built-in potentiometer or encoder to be used, and slow opening and closing are achieved through motor speed regulation, with torque protection function to prevent jamming.
[0030] Optionally, the level gauge 10 is a radio frequency admittance level gauge, a capacitive level gauge, or an ultrasonic level gauge. Its purpose is to monitor the dust accumulation inside the heavy dust removal hopper 1, so as to facilitate the rapid discharge of dust and avoid affecting the dust removal efficiency.
[0031] In addition, radio frequency admittance level gauges transmit high-frequency radio signals to dust through a probe and measure the change in admittance value between the dust and the probe. When the dust comes into contact with the probe, it causes a sudden change in the admittance value, triggering a switching signal. Capacitive level gauges measure dust height by detecting changes in capacitance. Capacitive level gauges have the advantages of simple structure and no moving parts. The probe and the inner wall of the heavy removal unloading box 1 form the two poles of a capacitor, and the dust acts as the dielectric, thereby detecting the dust height. Ultrasonic level gauges detect the dust height through an ultrasonic probe. Therefore, these three types of level gauges 10 can be used to monitor the dust height, and their monitoring effect is good.
[0032] Optionally, the controller 7 is a PLC controller or a microcontroller controller. Its purpose is to enable the controller 7 to receive signals from the level gauge 10 and control the opening and closing of the ash discharge valve 5, thereby further improving the automation of the heavy removal discharge box 1.
[0033] Optionally, both the ash discharge valve 5 and the level gauge 10 are electrically connected to the controller 7 to receive signals from the level gauge 10 and control the opening and closing of the ash discharge valve 5. This allows the ash discharge valve 5 and the level gauge 10 to cooperate with each other, facilitating the discharge of dust from the inside of the heavy removal feed box 1.
[0034] Optionally, the first sealing block 3 is located at the connection between the heavy removal discharge port 2 and the ash discharge valve 5, and the second sealing block 9 is located at the connection between the feed port 8 and the level gauge 10. Their function is to keep the inside of the heavy removal discharge box 1 sealed, thereby effectively preventing dust leakage and protecting the environment.
[0035] Working principle: When the dust inside the heavy dust removal hopper 1 accumulates to a certain height, the level gauge 10 will transmit a signal to the controller 7. The controller 7 will control the ash discharge valve 5 to discharge the dust. After the dust is discharged, the level gauge 10 will transmit a signal to the controller 7. The controller 7 will control the ash discharge valve 5 to close. The alarm 6 is electrically connected to the controller 7. When the dust accumulation height exceeds the set value, the controller 7 will control the alarm 6 to sound an alarm, reminding the staff to deal with it in time.
