Description

Technical Field

[0001] This utility model relates to the technical field of casting equipment, and in particular to a sand removal and dust collection device. Background Technology

[0002] In the casting production process, the sand removal process generates a large amount of dust. This dust not only seriously pollutes the working environment and endangers the health of operators, but may also affect product quality. Existing sand removal dust collection devices have several problems. For example, water curtain sand removal dust collection devices consume a lot of water, are prone to freezing in cold winters, and have limited effectiveness in handling fine dust; pulse bag sand removal dust collection devices have easily damaged filter bags, poor adaptability to dust with high humidity, and high operating resistance; cyclone sand removal dust collection devices have low dust removal efficiency for fine dust, large pressure loss, and are greatly affected by the properties of the dust; and dust suction hood sand removal dust collection devices have dust suction efficiency greatly affected by the hood design and have limited capacity to handle large volumes of dust. Therefore, a new type of sand removal dust collection device is needed to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sand dust removal device with high-efficiency composite dust removal, flexible adaptation to different working conditions, and intelligent control.

[0004] This utility model provides a sand removal and dust collection device, comprising:

[0005] A dust collection hood is installed above the sand removal station;

[0006] Dust collectors include cyclone dust collectors and bag dust collectors. The dust collection hood is connected to the air inlet of the cyclone dust collector, the air outlet of the cyclone dust collector is connected to the air inlet of the bag dust collector, and the air outlet of the bag dust collector is connected to the air inlet of the fan.

[0007] The humidification component is installed on the pipeline between the cyclone dust collector and the bag dust collector. It includes a duct and multiple spray pipes. The duct has an air inlet and an air outlet at both ends. The multiple spray pipes are installed inside the duct and connected to a water source through a pump body. The spray pipes have multiple nozzles. A water guide trough is installed at the bottom of the duct. The water guide trough is connected to the duct through a connecting port. A guide plate is installed at the connecting port.

[0008] Dust collection hoppers are installed at the bottom of cyclone dust collectors and bag dust collectors;

[0009] The control unit connects to the dust hood, cyclone dust collector, bag filter, fan, and humidification unit.

[0010] Furthermore, the dust hood adopts an adjustable structure, including a top cover and multiple movable side panels installed at its bottom. The side panels are connected by fasteners, the top cover is fixed to the base by a bracket, and the side panels are adjusted in position by a telescopic rod.

[0011] Furthermore, multiple nozzles are vertically spaced apart, and each nozzle has a rhomboid structure, with the sides of the rhombus facing the air inlet side and the nozzle located on the side away from the air inlet.

[0012] Furthermore, the dust collection hopper adopts a sealed structure and is equipped with a discharge port for easy dust cleaning.

[0013] Furthermore, the control components include sensors and a controller. The sensors monitor the parameters of the sand-falling area in real time and transmit the data to the controller. The controller controls the dust collection hood, cyclone dust collector, bag dust collector, fan, and humidification components according to preset parameters and algorithms.

[0014] Furthermore, the control components also include a remote monitoring module.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By combining a cyclone dust collector with a bag filter, the cyclone dust collector is first used to initially separate larger dust particles, and then the bag filter is used to filter fine dust. This effectively improves the ability to handle dust of different particle sizes. Compared with a single cyclone or pulse bag filter, the dust removal efficiency is higher, which can better ensure product quality and reduce dust pollution to the working environment.

[0017] 2. A humidification component is installed between the cyclone dust collector and the bag filter to humidify the dust entering the bag filter, reducing its humidity and mitigating problems such as easy damage to the filter bags and high operating resistance caused by high dust humidity. This makes the bag filter more adaptable to dust with high humidity. Compared to water curtain-type sand removal dust collectors, which are prone to icing in cold winters, this device does not use a large amount of water for dust removal, thus avoiding the impact of icing on normal operation in cold winters.

[0018] 3. The dust hood adopts an adjustable structure. The position of the side plate is adjusted by the telescopic rod. The size and shape of the dust hood can be flexibly adjusted according to the actual situation of the sand removal station, which improves the dust removal effect and solves the problem that the dust removal effect of the dust hood type sand removal dust removal device is greatly affected by the design of the hood. It can also better adapt to the handling of large air volume dust under different sand removal conditions.

[0019] 4. The control components include sensors, controllers, and a remote monitoring module. The sensors monitor the parameters of the sand-falling area in real time, and the controller controls each component according to preset parameters and algorithms to realize the automated operation of the device. It can adjust the equipment operating status in a timely manner according to the actual working conditions, thereby improving dust removal efficiency and equipment operation stability. The remote monitoring module allows operators to remotely monitor the equipment operation, promptly identify and handle potential problems, and improve the convenience and efficiency of equipment management.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] like Figure 1 As shown, the present invention provides a sand removal and dust collection device, comprising:

[0028] Dust hood 1 is installed above the sand removal station; the dust collector includes a cyclone dust collector 2 and a bag dust collector 3. The dust hood 1 is connected to the air inlet of the cyclone dust collector 2, the air outlet of the cyclone dust collector 2 is connected to the air inlet of the bag dust collector 3, and the air outlet of the bag dust collector 3 is connected to the air inlet of the fan 4.

[0029] Humidification component 5 is installed on the duct between cyclone dust collector 2 and bag dust collector 3;

[0030] Dust collection hopper 6 is installed at the bottom of cyclone dust collector 2 and bag dust collector 3;

[0031] The control component 7 is connected to the dust collection hood 1, the cyclone dust collector 2, the bag dust collector 3, the fan 4, and the humidification component 5;

[0032] Dust generated during sand removal is directly captured by the dust collection hood 1, preventing dust from spreading within the workshop at its source, effectively controlling dust pollution and maintaining a clean working environment. The cyclone dust collector 2 uses centrifugal force to separate large dust particles first, reducing the filtration burden on the bag filter 3 and extending the service life of the filter bags. The bag filter 3 then efficiently filters the remaining fine dust. The two are connected sequentially by pipes, leveraging their respective strengths to greatly improve overall dust removal efficiency, effectively purifying the air and meeting dust emission standards. The humidification component 5 humidifies the dust-laden gas about to enter the bag filter 3. Wet treatment reduces the stickiness and electrostatic effect of dust, preventing dust from clumping and clogging the filter bag surface, thereby reducing filter bag wear, reducing replacement frequency, improving the operational stability of the bag filter 3, and enhancing the ability to handle dust with high humidity; the dust collection hopper 6 collects the dust separated by the cyclone dust collector 2 and the bag filter 3, making it convenient for staff to handle the collected dust and reducing the difficulty and workload of manual cleaning; the control component 7 monitors in real time through sensors and automatically controls the operation of each component according to preset parameters and algorithms to achieve intelligent operation and ensure efficient and stable dust removal under different working conditions.

[0033] like Figure 2 As shown, the dust hood 1 adopts an adjustable structure, including a top cover 11 and multiple movable side panels 12 installed at its bottom. The side panels 12 are connected by fasteners, and the top cover 11 is fixed to the base by a bracket 13. The side panels 12 are adjusted in position by a telescopic rod 14. The fixed top cover 11 by the bracket 13 provides stable overhead coverage, ensuring a basic dust collection range. The multiple side panels 12 are linked by fasteners to ensure the overall structural stability. When the side panels 12 are lowered and completely cover the workstation, the space for dust diffusion is greatly reduced. This creates a relatively enclosed area, making it easier for dust to be drawn into the dust collection hood 1 when the fan 4 generates negative pressure. This significantly improves dust collection efficiency, reduces dust dispersion in the workshop, lowers pollution to the working environment, and protects the health of operators. The enclosed space also optimizes airflow within the dust collection hood 1. During dust collection, a more stable airflow prevents dust from accumulating in localized areas, allowing dust to flow more smoothly to the dust collector, further improving the overall efficiency of the dust collection system. At the same time, it reduces secondary dust re-entrainment caused by turbulent airflow.

[0034] like Figure 3 and Figure 4 As shown, the humidification component 5 includes:

[0035] The conduit 51 has an air inlet and an air outlet at its two ends, respectively.

[0036] Multiple nozzles 52 are installed inside the conduit 51 and connected to the water source through the pump body 54. Multiple nozzles 53 are provided on the nozzles 52.

[0037] The dust-laden airflow enters through the inlet of duct 51, and the spray nozzle 52 sprays water mist into the airflow through the nozzle 53. The fine water droplets come into contact with the dust particles, causing the dust to adsorb and agglomerate, forming larger particles, which is beneficial for the subsequent interception of dust by the bag filter 3 and improves the dust removal efficiency. The pump body 54 can precisely control the amount of water sprayed according to the actual working conditions and dust characteristics. For example, for dust with high humidity requirements, the water supply of the pump body 54 can be increased; for dust with low humidity requirements, the water supply can be reduced accordingly, thereby ensuring that the entire dust removal system can adapt to the treatment needs of different dusts.

[0038] A water guide trough 55 is installed at the bottom of the duct 51. The water guide trough 55 is connected to the duct 51 through a connecting port 56, and a guide vane 57 is installed at the connecting port 56. During the humidification process, some water droplets will settle to the bottom of the duct 51. The water guide trough 55 can collect these water droplets in time, preventing water from accumulating in large quantities at the bottom of the duct 51 and preventing water from affecting the normal passage of dust-laden airflow, thus ensuring the stable operation of the dust removal system. The guide vane 57 is used to guide the airflow. On the one hand, it prevents the airflow from directly impacting the connecting port 56 and causing airflow turbulence, allowing the airflow to pass smoothly through the duct 51 and ensuring that dust and water mist are fully mixed. On the other hand, it guides the settled water droplets to the water guide trough 55, improving the water collection efficiency and further ensuring the stability of the airflow inside the device and the humidification effect. The water guide trough 55 is independent of the duct 51, making it easier to clean water and perform maintenance, reducing maintenance costs and time.

[0039] Multiple nozzles 52 are vertically spaced, and each nozzle 52 has a rhomboid structure, with the sides of the rhombus facing the air inlet side and the nozzle 53 located on the side away from the air inlet side. This design creates a multi-layered spray area along the height of the duct 51. When the dust-laden airflow passes through the duct 51, the nozzles 52 at different heights simultaneously spray water mist into the airflow, making the water mist more evenly distributed across the cross-section of the duct 51. This increases the contact area and probability between the water mist and the dust, thereby improving the humidification effect on the dust and allowing more dust to absorb moisture, promoting humidification. The agglomeration and settling of dust particles; compared with other shapes, the rhomboid structure can make the airflow more smoothly diverted under the impact of airflow, effectively reducing the resistance of the nozzle 52 to the dust-laden airflow, reducing the turbulence and vortex formed around the nozzle 52, reducing energy loss, and ensuring the stable flow of airflow in the duct 51; the nozzle 53 facing away from the air inlet side can avoid the direct impact of the dust-laden airflow. If the nozzle 53 faces the air inlet side, the high-speed dust-laden airflow may blow dust particles into the nozzle 53, causing the nozzle 53 to be blocked, affecting the spray effect and the normal operation of the humidification component 5.

[0040] The dust collection hopper 6 adopts a sealed structure and is equipped with a discharge port for easy dust cleaning. The sealed structure can effectively prevent the collected dust from leaking back into the working environment. In dusty environments such as foundries, if the dust collection hopper 6 is not sealed, the dust may spread with the airflow in the workshop, causing secondary pollution and endangering the health of operators. The sealed structure avoids this problem and maintains a clean production environment in the workshop. The discharge port reduces the difficulty of cleaning the dust collection hopper 6. When cleaning is required, the discharge port can be opened to easily discharge the dust, reducing the time and workload of manual cleaning and improving cleaning efficiency.

[0041] The control component 7 includes sensors and a controller. The sensors monitor parameters in the sand-falling area in real time and transmit the data to the controller. The controller controls the dust collection hood 1, cyclone dust collector 2, bag dust collector 3, fan 4, and humidification component 5 according to preset parameters and algorithms. The sensors monitor parameters in the sand-falling area in real time, such as dust concentration and humidity, and can promptly capture changes in the working conditions of the sand-falling area, transmitting this data to the controller in real time. When the sensors detect an increase in dust concentration, the controller can instruct the fan 4 to increase its speed to enhance dust collection capacity. Based on humidity data, the controller adjusts the water spray volume of the humidification component 5 to ensure that each component is always in optimal operating condition to maintain a highly efficient and stable dust removal effect.

[0042] The control component 7 also includes a remote monitoring module; with the help of the remote monitoring module, managers can obtain the operating parameters and working status of the sand removal and dust collection device in real time; for example, they can view the suction power of the dust collection hood 1, the inlet and outlet pressures of the cyclone dust collector 2 and the bag dust collector 3, the speed of the fan 4, the water spray volume of the humidification component 5, etc., which enables managers to grasp the overall operation of the equipment in a timely manner, make quick decisions, and improve the timeliness and accuracy of management.

[0043] This utility model discloses a sand removal and dust collection device. During operation, the telescopic rod 14 is first extended, driving the side plate 12 to descend and completely cover the sand removal station. The fan 4 is turned on to generate negative pressure, initiating the sand removal process. Dust is stirred up, and the dust collection hood 1 captures the dust. The dust-laden gas flows from the dust collection hood 1 through the connecting pipe to the inlet of the cyclone dust collector 2. After entering the cyclone dust collector 2 tangentially, the dust-laden gas spirals downwards along the cylinder wall, forming an outer vortex. Under centrifugal force, large dust particles are thrown against the cylinder wall and fall along it, entering the dust collection hopper 6 at the bottom through the dust outlet. The purified gas then moves upwards along the axis, forming an inner vortex, and is discharged from the outlet. The gas, after preliminary dust removal, enters the duct 51, where the pump 54 draws water and sprays water mist into the dust-laden airflow through the nozzle 53 on the spray pipe 52, thus reducing dust accumulation. Dust agglomerates, and unevaporated water droplets settle to the bottom of the duct 51, then are guided by the air guide plate 57 into the water guide trough 55. The dust-laden gas, after being humidified and agglomerated, enters the bag filter 3. Fine dust is intercepted by the filter bags, and the purified gas is discharged by the fan 4. As dust continues to accumulate on the surface of the filter bags, the controller controls the bag filter 3 to perform a dust cleaning operation in a timely manner according to preset parameters, so that the intercepted dust falls into the dust collection hopper 6. Sensors monitor the parameters of the dust collection area in real time and transmit the data to the controller. The controller performs intelligent control of each component according to preset parameters and algorithms. The remote monitoring module transmits the equipment operating parameters and status in real time, which can be viewed remotely by management personnel. The discharge port of the dust collection hopper 6 is opened periodically to discharge and clean the collected dust. After the discharge port is closed, the dust collection hopper 6 remains sealed to prevent dust leakage.

[0044] The dust removal device of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
