Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of powder classifiers, specifically to a powder classifier with a discharge humidification function. Background Technology
[0002] As the core equipment for material sorting, the air classifier is widely used in industrial production. During the crushing of solid stone, a large amount of stone powder and fine particles are generated. In order to sort out the sand powder with a predetermined fineness modulus, it is necessary to use an air classifier to separate out the excessively fine dust and particles.
[0003] Currently, there are various types of air classifiers on the market, such as dynamic and static air classifiers. Their structure includes a hopper with a feed inlet, an air inlet, a fine material outlet, and a coarse material outlet. After the material enters the air classifier chamber, the falling direction of the material at the grid position intersects with the direction of the sorting airflow. The strong airflow carries away the dust in the material, and the dust is discharged from the air vent of the air classifier.
[0004] However, the practicality and efficiency of current powder classifiers in separating coarse, fine, and fine powder materials need improvement. They cannot effectively perform multi-stage separation. Furthermore, during the discharge stage, dust is generated during the conveying of sand and gravel after screening by the powder classifier. Water treatment is required to keep the powder moist and prevent dust generation, thus meeting environmental protection requirements. Currently, water treatment technology uses direct water supply through water pipes, which cannot completely eliminate dust and wastes water resources. Therefore, we propose a powder classifier with discharge humidification function. Utility Model Content

[0019] Compared with the prior art, this utility model provides a powder classifier with discharge humidification function, which has the following beneficial effects:
[0020] 1. This powder classifier with discharge humidification function, in order to better classify powder, is equipped with a sorting component. When the initial material is conveyed into the control box through the feed hopper, it is combined with inclined plates, baffles, baffles, guide plates and baffles to allow coarse material to enter the coarse material box through the coarse material inlet. Before feeding, the fan is started, and with the help of the air outlet pipe and the air outlet filter plate, the airflow blows the fine material into the fine material box through the fine material inlet. With the help of rectangular plates and rectangular filter plates, the fine powder is blown into the fine powder box. With the help of U-shaped pipe, first circular filter plate, air inlet pipe and second circular filter plate, the airflow is better circulated in the control box. With the help of arc plate, the fine powder is prevented from being blown directly onto the first circular filter plate, thus enabling better powder classification and improving production efficiency.
[0021] 2. This powder classifier with discharge humidification function improves the practicality of the device by setting up a humidification component. When coarse and fine materials are discharged, the water pump is activated, allowing water to flow through the hose and into the annular pipe on the connecting rod. The water is then sprayed through the nozzles into the coarse and fine material boxes, thus preventing dust from being generated during the discharge process. At the same time, opening the box door allows for better cleaning of residual materials on the inclined plate and baffle, thereby improving the practicality of the device. Attached Figure Description

[0035] Please see Figures 1-7 This utility model provides a technical solution:
[0036] A powder classifier with discharge humidification function includes a frame 1, a support 2 fixedly installed on the top of the frame 1, an operation box 3 fixedly installed on the top of the support 2, a loading and unloading mechanism on the operation box 3, the loading and unloading mechanism including a feed hopper 4, the feed hopper 4 is provided on the top of the operation box 3, a coarse material inlet 5 and a fine material inlet 6 are provided at the bottom of the operation box 3, a coarse material box 7 and a fine material box 8 are placed on the top of the frame 1, the coarse material box 7 and the fine material box 8 are respectively located below the coarse material inlet 5 and the fine material inlet 6, and a fine powder box 9 is also snapped into the bottom of the operation box 3.
[0037] In one embodiment of this utility model, a sorting component 10 is provided at the top of the frame 1. The sorting component 10 includes an inclined plate 101. The inclined plate 101 is fixedly installed inside the operation box 3. A baffle 102 is fixedly installed on the upper surface of the inclined plate 101. In addition, multiple sets of baffles 102 are provided, and the multiple sets of baffles 102 are located below the feed hopper 4 to better separate the lumpy material from the powder. A baffle 103 is fixedly installed on the inner wall of the top of the operation box 3, and a baffle 103 is fixed on the inner wall of the bottom of the operation box 3. A guide plate 104 and a baffle 105 are installed, with the guide plate 104 penetrating the baffle 105. Two sets of guide plates 104 are provided, and the two sets of guide plates 104 are mirror-oriented and inclined at both ends of the coarse material inlet 5 and the fine material inlet 6, allowing the material to enter the coarse material inlet 5 and the fine material inlet 6 more effectively. A rectangular plate 106 is fixedly installed inside the control box 3 at the end away from the inclined plate 101. A rectangular filter plate 107 is fixedly installed at the bottom of the rectangular plate 106, and the bottom of the rectangular filter plate 107 is attached to the baffle. A fan 108 is fixedly installed on the top of the control box 3 on the outer wall of the frame 105. One end of the air outlet pipe 109 is fixedly connected to the output end of the fan 108. The other end of the air outlet pipe 109 passes through the bottom of the control box 3. An air outlet filter plate 1010 is fixedly installed inside the end of the air outlet pipe 109 away from the fan 108. Both ends of a U-shaped pipe 1011 are fixedly installed inside the side wall of the control box 3. A first circular filter plate 1012 is fixedly installed inside the bottom end of the U-shaped pipe 1011. The input end of the fan 108... One end of the air inlet pipe 1013 is fixedly connected, and the other end of the air inlet pipe 1013 passes through the top of the control box 3. A second circular filter plate 1014 is fixedly installed inside the air inlet pipe 1013. In addition, two sets of fans 108, air outlet pipe 109, air outlet filter plate 1010, air inlet pipe 1013 and second circular filter plate 1014 are provided to make the airflow better. An arc plate 1015 is fixedly installed at the bottom of the rectangular plate 106 near the first circular filter plate 1012.
[0038] In this embodiment, the initial material is fed into the operating box 3 through the top opening of the feed hopper 4 and slides down into the operating box 3 by gravity. When the material hits the inclined surface of the inclined plate 101, larger particles impact the baffle array 102, which hinders the material from sliding down, causing initial separation between the blocky material and the powder. The baffle 103 is fixed to the inner wall of the top of the operating box 3 and extends horizontally, blocking the upward splashing material and forcing it to change its direction of movement and fall downward. The guide plate 104 is installed on the inner wall of the bottom of the operating box 3 in two sets of mirror-image inclined configurations, with its inclined surface facing the coarse material inlet 5 and the fine material inlet 6. When the material falls, the coarse particles, due to their greater weight, slide along the inclined surface under the guidance of the guide plate 104 and fall from the coarse material inlet 5 into the coarse material box 7 below. Before the material is fed in, the fan 108 is started. The fan 108 delivers airflow into the operating box 3 through the air outlet pipe 109. The air outlet filter plate 1010 prevents debris from entering. The airflow in the box will... Fine particles and powder are blown up. Due to their larger particle size, the fine particles are blocked by the mesh structure of the rectangular filter plate 107 (fixed to the bottom of the rectangular plate 106) and cannot pass through the rectangular filter plate 107. Therefore, they are blown into the fine material box 8 from the fine material inlet 6 under the push of the airflow. The fine powder passes through the mesh of the rectangular filter plate 107 and continues to move towards the bottom of the operating box 3 with the airflow, and finally falls into the fine powder box 9. The two ends of the U-shaped tube 1011 are fixed to the side wall of the operating box 3. The first circular filter plate 1012 is installed in the tube to intercept the fine powder in the airflow for a second time. The blower 108 draws in the circulating airflow in the operating box 3 through the air inlet pipe 1013. The second circular filter plate 1014 in the air inlet pipe 1013 filters the airflow again. The arc plate 1015 is installed at the bottom of the rectangular plate 106 near the first circular filter plate 1012. Its arc surface guides the direction of the airflow, avoids the fine powder from directly impacting the first circular filter plate 1012, reduces the risk of filter plate blockage, and improves the airflow circulation efficiency.
[0039] In one embodiment of this utility model, a humidification assembly 11 is further provided on the outside of the operation box 3. The humidification assembly 11 includes a water pump 111. The water pump 111 is fixedly installed on the top of the frame 1. The input end of the water pump 111 is connected to a water supply device. The output end of the water pump 111 is fixedly connected to one end of a flexible hose 112. A circular annular tube 114 is fixedly installed on the other end of the flexible hose 112. A connecting rod 113 is fixedly installed on the bottom of the operation box 3. The bottom of the connecting rod 113 is fixedly connected to the outer wall of the circular annular tube 114. A nozzle 115 is fixedly installed at the bottom of the annular tube 114. The annular tube 114 is located directly above the coarse material box 7 and the fine material box 8. In addition, there are multiple sets of nozzles 115, and all sets of nozzles 115 are arranged in a circular array with the center of the circular cross section of the annular tube 114 as the array center, which makes the humidification effect better. In addition, a door 116 is hinged to the side wall of the control box 3 away from the U-shaped tube 1011, which can better clean the residual material on the inclined plate 101 and the baffle 102.
[0040] In this embodiment, when the coarse material bin 7 and fine material bin 8 are discharging materials, the water pump 111 (the input end of the water pump 111 is connected to an external water supply device) is started. The water flows through the hose 112 to the annular pipe 114 supported by the connecting rod 113. Multiple sets of nozzles 115 (installed in a circumferential array) evenly distributed at the bottom of the annular pipe 114 atomize the water flow into a fine water mist, covering the discharge area of the coarse material bin 7 and fine material bin 8. The water mist combines with the dust particles generated during the discharge process, making the dust heavier and causing it to settle quickly under gravity, effectively suppressing dust overflow. The box door 116 is opened, and the operator can easily remove the remaining blocky materials on the inclined surface of the inclined plate 101 and the powder accumulation between the baffles 102 by manual cleaning or blowing with tools, avoiding material residue from affecting the subsequent powder selection accuracy, ensuring the continuous and stable operation of the equipment, and thus improving the overall practicality of the device.
[0041] All electrical components mentioned in this application are electrically connected to the PLC controller and 220V AC mains power. The PLC controller is a conventional and known device that can control the fan 108 and the water pump 111. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. The supporting structures of the hydraulic drive structure mentioned in this application, such as the hydraulic tank and hydraulic pump, are existing equipment and will not be described in detail here.
[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
