Description

Technical Field

[0001] This utility model belongs to the field of feeding machine technology, specifically relating to a dust-free metering feeding machine. Background Technology

[0002] In the production processes of industries such as chemicals, food, and pharmaceuticals, it is often necessary to put various raw materials into reaction vessels or other equipment in a certain proportion. In order to avoid dust particles being raised during feeding and to ensure that the working environment of the staff is free from dust, a dust-free feeding machine is used. During feeding, the dust raised is sucked in by the separator and transported back to the discharge hopper through the pipeline, thereby avoiding the occurrence of dust. Existing dust-free feeding machines, lacking metering equipment, are prone to sucking up too much or too little material during the dust intake process. Material accumulation in the hopper can lead to fan blockage, significantly reducing production efficiency and failing to meet the demands of large-scale production. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 As shown in Figure 5, this embodiment provides a dust-free metering and feeding machine, including a device body 1. The device body 1 contains a support frame 2. One end of the support frame 2 is connected to a conveying cylinder 3. A spiral auger 4 is provided inside the conveying cylinder 3 and is connected to a motor 5. A hopper 7 is connected above the conveying cylinder 3 and a discharge pipe 20 is connected to the rear end of the conveying cylinder 3. A cover plate 9 is provided above the hopper 7 and one end of the hopper 7 is connected to a feed pipe 13. A second motor 91 is provided on the cover plate 9, and a connecting rod 1 is connected below the second motor 91. 0. A fixing ring 11 is provided on the connecting rod 10. A stirring blade 12 is provided on the fixing ring 11. A metering pump 14 is connected below the feed pipe 13. One end of the metering pump 14 is connected to the material box 16. An inspection cover 21 is provided on the discharge pipe 20. A docking plate 22 is connected below the discharge pipe 20. A connecting plate 23 is provided below the docking plate 22. A flexible pipe 24 is connected below the connecting plate 23. Screw holes 25 are opened in the connecting plate 23 and the docking plate 22. Bolts 26 are provided in the screw holes 25. Nuts 28 are screwed onto the bolts 26.

[0020] Preferably, a fixing plate 6 is fixedly installed below the motor 5. One end of the fixing plate 6 is welded to one side of the support frame 2. By setting the fixing plate 6, the stability of the motor 5 during operation can be enhanced, the noise caused by vibration can be reduced, and the service life of the motor 5 and the equipment can be extended. A solenoid valve 8 is installed below the hopper 7. The solenoid valve 8 is specifically installed at the discharge port below the hopper 7. By installing the solenoid valve 8 at the discharge port of the hopper 7, the material discharge time and flow rate can be precisely controlled, the feeding accuracy can be improved, and the material supply can be cut off in time when the equipment needs to be stopped.

[0021] Preferably, a base 15 is provided below the material bin 16 and the metering pump 14. The base 15 provides stable support for them, ensuring the metering accuracy of the metering pump 14, and also facilitates the overall installation and handling of the equipment. Metering gauges 17 are installed inside the left and right ends of the material bin 16, and a sealing cover 18 is provided on the top of the material bin 16. A handle 19 is fixed on the sealing cover 18. By setting the metering gauges 17, the remaining amount of material in the material bin 16 can be monitored in real time, making it convenient to replenish the material in a timely manner. The handle 19 on the sealing cover 18 makes it easy to open and close the sealing cover 18, and the sealing cover 18 can prevent the material from getting damp or contaminated.

[0022] Preferably, multiple sets of nuts 28 are provided, each set of nuts 28 having an anti-slip groove 29. By providing the anti-slip groove 29, the friction between the nuts 28 and bolts 26 is increased, making the connection more secure and preventing the nuts 28 from loosening due to vibration during equipment operation, thus improving the safety and stability of the equipment. Both the mating plate 22 and the connecting plate 23 have installation grooves 30, and sealing rings 31 are sealed in the installation grooves 30, which can effectively prevent material leakage during the conveying process, ensure a dust-free environment during the feeding process, and also avoid material waste. The flexible tube 24 is made of elastic, stretchable, and shrinkable metal hose, which gives it good flexibility and corrosion resistance, can adapt to different installation spaces and working environments, and can also reduce blockage during material conveying. Multiple sets of bolts 26 are provided, each set of bolts 26 having a washer 27 movably fitted on it, which can distribute the pressure of the nuts 28 on the connecting plate 23 and the mating plate 22, protect the connection surface from damage, and further enhance the sealing performance of the connection.

[0023] The working principle and process of this utility model are as follows: In use, the user stores the material to be conveyed in the material box 16 in advance, adjusts the parameters of the metering pump 14, and the metering pump 14 accurately conveys the material into the hopper 7 through the feed pipe 13 according to the set parameters. Then, the control motor 2 91 drives the stirring blade 12 to rotate, stirring the material in the hopper 7 to prevent the material from clumping. The solenoid valve 8 controls the material to enter the conveying cylinder 3 from the hopper 7. The control motor 1 5 drives the spiral auger 4 to rotate, conveying the material from the front end of the conveying cylinder 3 to the rear end of the discharge pipe 20. The discharge pipe 20 is connected to the flexible pipe 24 through the docking plate 22 and the connecting plate 23. The material is finally delivered to the designated position through the flexible pipe 24. The sealing ring 31 between the docking plate 22 and the connecting plate 23 ensures that the material will not leak. The fastening effect of multiple bolts 26 and nuts 28 and the protection effect of the washer 27 ensure the stability and sealing of the connection.
