Description
Technical Field
[0001] This utility model relates to the field of dust separation and purification technology, specifically a dust collection device for a powder processing and conveying transfer station. Background Technology
[0002] In the processing and transportation of powder materials (such as cement, mineral powder, grain, chemical raw materials, etc.), transfer stations are among the most serious sources of dust pollution. Large amounts of dust-laden exhaust gas are generated during material transfer, unloading, and belt conveying. If discharged directly without treatment, this not only severely pollutes the surrounding environment but also causes material loss and poses a threat to the occupational health of operators.
[0003] Currently, dust removal solutions for powder conveying transfer stations mainly fall into two categories: baghouse dust collectors and cyclone dust collectors. While baghouse dust collectors offer high dust removal efficiency, the filter bags are prone to clogging when handling high-concentration, high-moisture dust, leading to a sharp increase in system resistance. This necessitates frequent shutdowns for cleaning or filter bag replacement, resulting in high maintenance costs. Cyclone dust collectors have lower collection efficiency for fine dust (particle size less than 10μm) and struggle to meet increasingly stringent environmental emission standards when used alone. Furthermore, existing transfer station dust removal systems often lack real-time monitoring of their internal operating status, failing to promptly detect malfunctions such as filter bag damage, pipe blockage, or abnormal dust concentration. This results in equipment operating with defects for extended periods, leading to high energy consumption and poor performance. Additionally, the dust generated during conveying is often accompanied by high temperatures, further increasing the difficulty of dust removal.
[0004] Therefore, how to design a dust collection device for a powder processing and conveying transfer station that can efficiently remove coarse and fine dust, operate stably, have internal condition monitoring functions, and is easy to maintain has become a technical problem that urgently needs to be solved in this field. Utility Model Content
[0005] The purpose of this utility model is to provide a dust collection device for a powder processing and conveying transfer station, which has the advantages of high dust collection efficiency, significant water mist dust reduction effect, convenient inspection and maintenance and high degree of automation, and solves the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A dust collection device for a powder processing and conveying transfer station includes a first dust collection tank, a dust collection and air inlet assembly fixedly connected to the lower end of the first dust collection tank, a maintenance and monitoring assembly fixedly connected to the upper end of the first dust collection tank, an air outlet assembly disposed on the lower part of the side wall of the first dust collection tank, a cyclone separator sealed and connected to the air outlet end of the air outlet assembly, an ash collection assembly disposed on the lower end of the cyclone separator, an exhaust assembly disposed on the upper exhaust end of the cyclone separator, a mist delivery pipe fixedly connected through to the upper part of the side wall of the first dust collection tank, a butterfly valve disposed on the mist delivery pipe, a water mist generating mechanism connected to the mist inlet end of the mist delivery pipe, and a controller disposed on the water mist generating mechanism; the controller is electrically connected to the exhaust fan, the maintenance and monitoring assembly, the water mist generating mechanism, and the butterfly valve respectively.
[0007] Preferably, the dust collection and air intake assembly includes a first cover fixedly connected to the lower end of the first dust collection tank, a dust collection pipe fixedly connected to the lower end of the first cover, and a first air collection hood fixedly connected to the lower end of the dust collection pipe.
[0008] It is worth noting that the first dust collection hood adopts a wide-mouth design, which can cover the dust area at the material drop point or belt transfer point of the transfer station to the maximum extent, effectively capturing the flying dust and preventing it from spreading to the surrounding environment; the dust extraction pipe serves as a conveying channel for dust-laden gas, drawing it into the first dust extraction tank for treatment.
[0009] Preferably, the maintenance monitoring component includes a first fixed cylinder fixedly connected to the upper end of the first dust collection tank, a maintenance cover threadedly installed on the upper end of the first fixed cylinder, a fixed rod fixedly connected to the lower end of the maintenance cover, a plurality of second fixed cylinders fixedly connected to the outer peripheral wall of the fixed rod, and a temperature and humidity sensor fixedly connected to the side wall of the second fixed cylinder; the controller is electrically connected to the temperature and humidity sensor.
[0010] It is worth noting that the inspection cover is installed with a thread, which makes it easy for operators to open it quickly and perform regular inspections or cleaning of the inside of the first dust collection tank. Multiple sets of temperature and humidity sensors are installed at intervals along the axial direction on the fixed rod, which can monitor the temperature and humidity distribution at different heights inside the tank in real time. When an abnormally high temperature is detected, the controller can issue an early warning signal in time to avoid safety accidents caused by dust spontaneous combustion or excessive water mist.
[0011] Preferably, the ash collection assembly includes an ash discharge pipe fixedly connected to the lower end of the cyclone separator, a first valve body disposed on the ash discharge pipe, and a collection box placed below the ash discharge pipe; the ash discharge end of the ash discharge pipe extends into the interior of the collection box; and the controller is electrically connected to the first valve body.
[0012] It is worth noting that the dust separated by the cyclone separator falls into the collection box through the ash discharge pipe for temporary storage. The design of the ash discharge pipe extending into the collection box can effectively prevent the dust from being re-entrained during the ash discharge process. The first valve body is electrically connected to the controller and can automatically open the ash discharge according to the set cycle, without the need for frequent manual operation, thus realizing the automated management of the ash discharge process.
[0013] Preferably, the air outlet assembly includes an air outlet box that is fixedly connected to the lower part of the side wall of the first dust collection tank, and a connecting frame that is fixedly connected to the air outlet end of the air outlet box; the air outlet end of the connecting frame is sealed and connected to the air inlet end of the cyclone separator.
[0014] It is worth noting that the air outlet box is located at the lower part of the side wall of the first dust collection tank, so that the dust-laden airflow after water mist condensation and settling can be smoothly discharged from the lower part of the tank; the connecting frame serves as an intermediate transition component, ensuring that the dust-laden airflow enters the cyclone separator at an appropriate flow rate and direction, providing stable airflow conditions for the efficient classification of the cyclone separator.
[0015] Preferably, the exhaust assembly includes a bent pipe fixedly connected to the upper exhaust end of the cyclone separator, a fixed pipe fixedly connected to the exhaust end of the bent pipe, a second valve body disposed on the fixed pipe, and a second gas collection hood fixedly connected to the exhaust end of the fixed pipe; the exhaust end of the second gas collection hood is fixedly connected to the air inlet end of the exhaust fan; the controller is electrically connected to the second valve body.
[0016] It is worth noting that the exhaust fan, as the power source of the entire dust removal system, draws in dust-laden gas through the dust collection and air inlet assembly, the first dust collection tank, and the cyclone separator before discharging clean gas. The bend and the fixed pipe constitute the exhaust pipeline, and the second valve can remotely control the airflow, making it easy for the system to quickly cut off the airflow during maintenance or emergency situations.
[0017] Preferably, the water mist generating mechanism includes a second cover fixedly connected to the end of the mist delivery pipe away from the first dust collection tank, and a third fixed cylinder fixedly connected to the end of the second cover away from the mist delivery pipe.
[0018] It is worth noting that the second cover serves as a transitional connector between the water mist generating mechanism and the mist delivery pipe, while the third fixed cylinder provides installation space and structural support for the water mist generating components, making the entire water mist generating mechanism an independent modular unit.
[0019] Preferably, the water mist generating mechanism further includes a water tank fixedly connected to the lower end of the third fixed cylinder, a support block fixedly connected to the inner wall of the third fixed cylinder, a water pump fixedly connected to the upper end of the support block, a water pumping pipe fixedly connected to the water pump's suction end and extending into the water tank, a water outlet pipe fixedly connected to the water pump's discharge end, a hollow disc fixedly connected to the inner wall of the third fixed cylinder, and multiple atomizing nozzles fixedly connected to the hollow disc near the first dust collection tank; the discharge end of the water outlet pipe is interconnected with the internal cavity of the hollow disc; and the controller is electrically connected to the water pump.
[0020] It is worth noting that the water pump draws water from the water tank and delivers it to the hollow disc cavity through the water outlet pipe. After pressure equalization, the water is sprayed out simultaneously by multiple atomizing nozzles to form a fine water mist. The mist delivery pipe is set through the upper part of the side wall of the first dust collection tank, which can directly deliver the water mist into the high-temperature dust-containing area inside the tank. The water mist and dust come into full contact and mix inside the tank. The dust particles are wetted and condensed by the water mist and settle down, achieving a pre-dust removal effect and reducing the dust load of the cyclone separator.
[0021] Preferably, a wastewater drain pipe is fixedly connected through the lower part of the side wall of the water tank, and a third valve body is installed on the wastewater drain pipe; the controller is fixedly connected to the side wall of the water tank; the controller is electrically connected to the third valve body.
[0022] It is worth noting that the third valve body is electrically connected to the controller. When the water quality deteriorates or the liquid level is too high due to the water mist spraying and circulation in the water tank, the controller can automatically open the third valve body to discharge the wastewater through the wastewater drain pipe to the external treatment system, thereby realizing automatic water quality renewal and intelligent control of the liquid level in the water tank.
[0023] Preferably, the end of the third fixed cylinder furthest from the first dust collection tank is configured as an open structure.
[0024] It is worth noting that the open structure design of the third fixed cylinder allows operators to easily perform daily inspections, cleaning, or replacements of components such as the water pump, hollow disc, and atomizing nozzle inside the cylinder, reducing maintenance difficulty and improving the operability of equipment maintenance.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model introduces water mist into the first dust collection tank by setting a water mist generating mechanism, so that the dust and water mist can fully contact, condense and settle, thus achieving pre-dust removal. Then, in conjunction with a cyclone separator, the residual fine dust is separated into gas and solid for a second time, forming a tiered dust removal system that combines wet and dry methods. This solves the problems of low efficiency and difficulty in removing both coarse and fine particles by a single dust removal method, and significantly improves the overall dust removal effect. 2. By setting up a two-stage series structure consisting of a first dust collection tank and a cyclone separator, most of the coarse dust particles condense and settle with water mist in the first dust collection tank, which greatly reduces the processing load of the cyclone separator, extends the service life of the cyclone separator, and reduces system energy consumption and operating costs. 3. This utility model, by setting up a maintenance monitoring component consisting of an inspection cover, a fixing rod, and a temperature and humidity sensor, realizes real-time monitoring of the temperature and humidity environment inside the first dust extraction tank, solves the problem of existing equipment lacking status monitoring means and being unable to detect the risk of dust spontaneous combustion in a timely manner, and ensures the safety and reliability of the device in long-term operation. 4. This utility model achieves automated control of water mist supply, airflow switching, and ash and sewage discharge by setting up a butterfly valve, a water pump, and a first valve body, a second valve body, and a third valve body that are electrically connected to the controller. It eliminates the need for frequent manual intervention and improves the intelligent operation level and ease of operation of the device. Attached Figure Description

The wastewater drain pipe 26 communicates with the interior of the water tank 25 and is used to discharge sewage or excess water that has settled at the bottom of the water tank 25.
[0039] In this embodiment, specifically, the end of the third fixed cylinder 21 furthest from the first dust extraction tank 1 is configured as an open structure. This opening is an open design without a baffle or cover, allowing operators to directly observe or contact the water pump 30, hollow disc 33, and atomizing nozzle 34 inside the third fixed cylinder 21 through the opening.
[0040] Working principle: During use, the first dust collection hood 4 is fixedly installed directly above the high dust point of the powder conveying transfer station. The speed of the exhaust fan 16 is adjusted to ensure that the system has a stable negative pressure suction capability. The controller 28 is started. The controller 28 issues instructions according to the preset intermittent working cycle: Under the condition that the exhaust fan 16 is running continuously, the controller 28 intermittently opens the butterfly valve 24 and starts the water pump 30. The water pump 30 draws water from the water tank 25 through the water pipe 31, pressurizes it through the water outlet pipe 32, and sends it into the cavity of the hollow plate 33. Then, multiple atomizing nozzles 34 atomize it into a fine water mist. The water mist is intermittently pulsed into the internal space of the first dust collection tank 1 through the second hood 22 and the mist delivery pipe 23. Dust-laden gas is captured by the first gas collecting hood 4 at the material drop point of the transfer station, and continuously drawn into the interior of the first dust collection tank 1 from bottom to top through the dust extraction pipe 3 and the first hood 2. As the dust-laden gas flows upward in the first dust collection tank 1, it forms a countercurrent contact with the water mist intermittently sprayed from the top. The dust particles are fully wetted and agglomerated by the water mist, forming dust agglomerates with significantly increased particle size and weight. Because the gravity of these agglomerates is much greater than the drag force of the rising airflow, most of them will overcome the airflow carrying force, sink downward and accumulate at the bottom of the first dust collection tank 1, realizing the first stage of efficient pre-dust removal, thereby greatly reducing the dust concentration and processing load of the subsequent cyclone separator 8. A small amount of fine dust that is not captured by the water mist enters the cyclone separator 8 with the rising airflow through the air outlet box 6 and the connecting frame 7. An airflow containing a small amount of fine dust enters the cyclone separator 8 and rotates at high speed along the inner wall of the cyclone separator 8. Under the action of centrifugal force, the residual dust is thrown against the wall and falls down the wall surface, falling into the collection box 11 through the ash discharge pipe 9, realizing the second stage of gas-solid separation. Clean gas is extracted from the upper end of the cyclone separator 8 through the bend pipe 12, the fixed pipe 13, and the second gas collection hood 15 by the exhaust fan 16 and discharged. The wet dust accumulated at the bottom of the first dust collection tank 1 can be manually cleaned periodically after the machine is stopped, or discharged through the added ash discharge valve (which can be added as needed). The intermittent spraying of water mist ensures sufficient contact and condensation between dust and mist droplets, while avoiding excessive wetting of dust that would cause it to adhere to the tank wall or block the airflow channel due to continuous water spraying. During equipment operation, the controller 28 monitors the temperature and humidity inside the first dust collection tank 1 in real time through the temperature and humidity sensor 20. When an abnormal temperature rise is detected, the controller 28 can increase the opening of the butterfly valve 24 or increase the operating frequency of the water pump 30 to perform cooling and humidification treatment to prevent dust from spontaneously combusting. The dry dust in the collection box 11 is transferred and treated periodically, while the wastewater in the water tank 25 is discharged periodically through the wastewater drain pipe 26 by opening the third valve body 27.
