Description

Technical Field

[0002] In product production, powder is often used as a raw material. How to convey the powder to the working station and ensure the accuracy of the conveying volume is an urgent problem to be solved in current powder conveying. Now powder conveying is widely used in the conveying of light dry powders such as food powder, agricultural product powder, metal powder, chemical powder, etc. Common conveying methods include pneumatic conveying, tube chain conveying, etc.

[0003] In the prior art, such as the utility model patent with the application number CN202322248073.X, a powder metering and conveying device is disclosed, including a main body. A back frame is arranged at the front end of the main body, a fixed clamp is arranged at one end of the main body, a stirring mechanism is installed in the middle of the fixed clamp, a feeding port is arranged on one side of the upper end of the stirring mechanism, a conveying mechanism is installed at the lower end of the stirring mechanism, a metering mechanism is installed at the lower left end of the conveying mechanism, a seat frame is arranged on the outer side of the lower end of the metering mechanism, and a support is arranged at the lower end of the conveying mechanism. In the present utility model, the stirring cylinder is installed in the middle inside the fixed clamp. During use, the driving motor is driven, and then the stirring rod at the top is driven to rotate through the coupling, thereby synchronously driving the stirring blades to rotate, and the powder put in from the feeding port is dispersed during the rotation process, so as to avoid the situation that the powder forms a mass and causes low subsequent metering accuracy.

[0055] Embodiment 1:

[0056] As Figure 1-4 shown, the present invention provides an intelligent powder conveyor, including:

[0057] A feeding unit 1, in which a dust removal fan 4 of the feeding station is provided to remove the dust mixed in the powder;

[0058] The metering and discharging unit is connected to the output end of the feeding unit. There are two sets of metering and discharging units, namely the first metering and discharging unit 2 and the second metering and discharging unit 3. A metering tank 8 is provided in the metering and discharging unit for metering and discharging the powder.

[0059] The powder quantity control unit is connected to the feeding unit 1 and the metering and discharging unit, and is used to control the powder feeding quantity of the feeding unit 1 and the powder discharging quantity of the metering and discharging unit.

[0060] The working principle and beneficial effects of the above technical solution are as follows:

[0061] For an intelligent powder conveyor, during use, the powder to be conveyed is put into the feeding unit 1. The dust removal fan 4 of the feeding station provides air flow power for the feeding unit 1 to remove the dust in the input powder. The dust-removed powder is respectively conveyed into the first metering and discharging unit 2 and the second metering and discharging unit 3 under the air flow power, and then discharged through the metering tank 8. By setting the powder quantity control unit, the powder feeding quantity of the feeding unit 1 can be set, so that the feeding unit 1 feeds the powder according to the preset powder quantity; the powder discharging quantity of the metering tank 8 can be set, so that the metering tank 8 discharges the powder according to the preset powder quantity.

[0062] Through the above structural design, an intelligent powder conveyor is provided. By setting two metering and discharging units, the powder can be discharged separately or simultaneously, improving the powder discharging efficiency; by setting the dust removal fan 4 of the feeding station, the dust in the input powder is removed, improving the accuracy of the powder discharging quantity; by setting the powder quantity control unit to monitor and control the powder feeding quantity and the powder discharging quantity, the function of quantitative discharging can be realized, thereby improving the intelligence of powder conveying.

[0063] Further, the feeding unit 1 includes: a dust removal fan 4 of the feeding station, a dust removal tank 5 and a first discharging screw 6. The dust removal fan 4 of the feeding station is connected to the air inlet end of the dust removal tank 5 and is used to provide power for dust separation and powder conveying in the dust removal tank 5; the first discharging screw 6 is connected to the discharging end of the dust removal tank 5, and the first discharging screw 6 is connected to the metering and discharging unit.

[0064] Put the powder into the dust removal tank 5. Under the action of the air flow of the dust removal fan 4 of the feeding station, the powder is separated from the dust mixed in it, improving the cleanliness of the powder and facilitating the detection of the actual discharging quantity of the feeding unit 1. The first discharging screw 6 is arranged at the discharging end of the dust removal tank 5, and the first discharging screw 6 forms a spiral movement track in the discharging pipeline to convey the powder along the pipeline to the discharging port, improving the continuity and uniformity of the discharging process.

[0065] Further, the metering and discharging unit includes: a feeding machine 7 and a metering tank 8. The feeding end of the feeding machine 7 is connected to the discharging end of the first discharging screw 6, and the feeding end of the metering tank 8 is connected to the discharging end of the feeding machine 7. The feeding machine 7 is used to feed the metering tank 8.

[0066] Further, a vibration distributor 9 is provided between the feeder 7 and the metering tank 8 of the first metering and discharging unit 2.

[0067] The vibration distributor vibrates and disperses the powder through mechanical vibration, enabling the powder to be evenly, regularly, and continuously conveyed from the feeder 7 into the metering tank 8.

[0068] Further, a second discharge screw 10 is provided between the feeder 7 and the metering tank 8 of the second metering and discharging unit 3. The second discharge screw 10 forms a spiral movement trajectory in the discharge pipeline, conveying the powder along the pipeline to the metering tank 8, improving the continuity and uniformity of the discharging process.

[0069] Further, the metering and discharging unit further includes a Roots blower 11, which is connected to the air inlet end of the feeder 7 and is used to provide power for the powder conveying in the feeder 7.

[0070] Further, the powder quantity control unit includes: a quantitative discharge valve 12 at the feeding station and a quantitative discharge valve 13 at the metering tank. The quantitative discharge valve 12 at the feeding station is arranged at the discharge end of the first discharge screw 6 and is used to monitor the actual discharge quantity of the feeding unit 1 and automatically close when the preset discharge quantity is reached; the quantitative discharge valve 13 at the metering tank is arranged at the discharge end of the metering tanks 8 of the first metering and discharging unit 2 and the second metering and discharging unit 3 and is used to detect the actual discharge quantity of the metering tank 8 and automatically close when the preset discharge quantity is reached.

[0071] Through the setting of the quantitative discharge valve 12 at the feeding station, the actual discharge quantity of the powder after dust removal can be accurately detected, improving the control accuracy of the powder feeding quantity. The quantitative discharge valve 13 at the metering tank can accurately detect the actual discharge quantity of the powder in the current discharging unit and monitor it at the discharging end, improving the control accuracy of the discharge quantity.

[0072] Further, the intelligent powder conveyor further includes: a control panel. The control panel and the powder quantity control unit are connected to the controller. The control panel is used to display the feeding states of the feeding unit 1, the first metering and discharging unit 2, and the second metering and discharging unit 3, and the user sets the preset feeding quantity and controls the start and stop of the feeding process through the control panel.

[0073] Through the setting of the control panel, the convenience of controlling the powder conveying operation is improved, making it easy to operate.

[0074] Further, the intelligent powder conveyor further includes: a status feedback unit. The status feedback unit is arranged at the valves of each component of the feeding unit 1, the first metering and discharging unit 2, and the second metering and discharging unit 3. The status feedback unit is electrically connected to the controller and is used to monitor the operating states of the valves and feedback them to the controller.

[0075] Furthermore, the intelligent powder conveyor further includes an operation indication unit and an alarm indication unit.

The fault and alarm situations are displayed on the control panel through the alarm indication unit, providing instructions for the staff and a basis for subsequent operation and maintenance operations.

[0077] Embodiment 2:

[0078] As Figure 5 、 6 shown, on the basis of the above Embodiment 1, the dust removal tank 5 includes:

[0079] A feed pipe 21, an air inlet pipe 22, and a discharge pipe 23. The feed pipe 21 and the discharge pipe 23 are respectively arranged on both sides of the top of the dust removal tank 5. The air inlet pipe 22 is arranged at the lower part of the side wall of the dust removal tank 5 and is located on the side far from the discharge pipe 23. The air inlet pipe 22 is connected to the dust removal fan 4 of the feeding station;

[0080] A main shaft motor 24, which is arranged at the top of the dust removal tank 5;

[0081] A main shaft 25, which is rotatably connected to the top end of the inner wall of the dust removal tank 5 and is connected to the output end of the main shaft motor 24. A main air inlet channel is arranged at the center of the main shaft 25, and the main air inlet channel is connected to the dust removal fan 4 of the feeding station;

[0082] A dispersion rod unit 26, and a plurality of dispersion rod units 26 are connected to the main shaft 25 at intervals for dispersing the powder.

[0083] The working principle and beneficial effects of the above technical solution are:

[0084] When the dust removal tank 5 is in use, powder is added into the dust removal tank 5 from the feed pipe 21. The dust removal fan 4 of the feeding station conveys air flow into the dust removal tank 5 through the air inlet pipe 22. The main shaft motor 24 is started to drive the main shaft 25 to rotate, and the dispersion rod unit 26 on the main shaft 25 rotates accordingly to disperse the added powder. Under the action of centrifugal force, the dust and particulate matters mixed in the powder move towards the inner wall of the dust removal tank 5 due to their greater weight. After colliding with the inner wall of the dust removal tank 5, they are discharged from the dust removal pipe at the bottom. The powder has a smaller weight. After being dispersed, it flows upward under the action of the air flow and is discharged through the discharge pipe 23. Through the above structural design, the dispersion rod unit 26 is arranged in the dust removal tank 5. By the high-speed rotation of the dispersion rod 26, the powder is dispersed, thereby reducing powder caking, facilitating the conveying of the powder, and improving the powder dust removal effect. And under the combined action of the air flow power and the rotational centrifugal force, the rapid separation of the powder and the dust particles is realized.

[0085] Embodiment 3:

[0086] As Figure 7 、 8 shown, on the basis of the above Embodiment 2, the dispersion rod unit 26 includes:

[0087] The first rod body 27, one end of the first rod body 27 is connected to the main shaft 25;

[0088] The second rod body 28, the second rod body 28 is connected to the other end of the first rod body 27. The diameter of the second rod body 28 is smaller than that of the first rod body 27. An air flow channel 29 communicating with the main air inlet channel is arranged at the centers of the first rod body 27 and the second rod body 28;

[0089] The air flow nozzle 31, the air flow nozzle 31 is connected to the end of the second rod body 28. The air inlet end of the air flow nozzle 31 is connected to the air flow channel 29;

[0090] The first guide cover 32, the first guide cover 32 is connected to the second rod body 28. The first guide cover 32 is arranged in an arc shape and bends towards the first rod body 27;

[0091] The first backwash nozzle plate 33, a plurality of first backwash nozzle plates 33 are connected to the side of the first guide cover 32 close to the first rod body 27. The first backwash nozzle plate 33 communicates with the air flow channel 29. A plurality of backwash ports are arranged on the first backwash nozzle plate 33;

[0092] The trigger piece 34, the trigger piece 34 is connected to the center of the first guide cover 32. After the trigger piece 34 receives a preset pressure, it opens the air inlet valve of the first backwash nozzle plate 33.

[0093] The working principle and beneficial effects of the above technical solution are:

[0094] When the dispersion rod unit 26 is in use, the dust removal fan 4 of the feeding station conveys the air flow into the main air inlet channel of the main shaft 25. The air flow flows from the main air inlet channel into the air flow channels 29 of the first rod body 27 and the second rod body 28, and then enters the air flow nozzle 31, and is sprayed out through the air flow nozzle 31. Through the above structural design, the problem that the air flow vortex is formed under the high-speed rotation state of the dispersion rod unit 26, resulting in the ineffective separation of the powder falling between the dispersion rod unit 26 and the inner wall of the dust removal tank 5 is solved; the air flow sprayed by the air flow nozzle 31 as a supplement can quickly disperse the powder falling between the dispersion rod unit 26 and the inner wall of the dust removal tank 5, and flow upward, reducing the loss of the powder during the dust removal process.

[0095] By providing the first backflush nozzle plate 33, when the air inlet valve of the first backflush nozzle plate 33 is opened, the first backflush nozzle plate 33 blows towards the main shaft 25 through the backflush ports, collides with the powder and dust particles moving outward under the action of centrifugal force, further improves the dispersion effect, increases the disturbance of the air flow, and at the same time cleans the inner side of the first deflector 32, the surfaces of the first rod body 27 and the second rod body 28, reducing dust adhesion.

[0096] Example 4:

[0097] As Figure 7 、 8 shown, on the basis of the above Example 1, the dispersion rod unit 26 further includes:

[0098] A second deflector 35, a slip ring 38 is provided at the center of the second deflector 35, the slip ring 38 is slidably connected to the second rod body 28, the second deflector 35 is arc-shaped and is adaptively arranged with the first deflector 32; the first deflector 32 and the second deflector 35 are magnetic and attract each other;

[0099] A second backflush nozzle plate 36, a plurality of second backflush nozzle plates 36 are connected to the second deflector 35, a plurality of ventilation ports are provided on the second backflush nozzle plate 36, and the positions of the ventilation ports on the second backflush nozzle plate 36 correspond to the positions of the backflush ports on the first backflush nozzle plate 33;

[0100] A spring 37, the spring 37 is sleeved on the second rod body 28, and both ends of the spring 37 are respectively connected to the first rod body 27 and the slip ring 38;

[0101] A slide rail 39, two slide rails 39 are symmetrically arranged on the first rod body 27, and a slider 41 is slidably arranged on the slide rail 39;

[0102] A first connecting rod 42, one end of the first connecting rod 41 is hinged to the slider 41;

[0103] A second connecting rod 43, both ends of the second connecting rod 43 are respectively hinged to the slip ring 38 and the other end of the first connecting rod 42;

[0104] The sealing cover is connected to the first rod 27 and is also connected to the first connecting rod 42, and is used to isolate the interior of the track of the slide rail 39 from the powder.

[0105] The working principle and beneficial effects of the above technical solution are as follows:

[0106] A second deflector 35 is provided on the second rod 28. When the main shaft 25 rotates at a high speed, the second deflector 35 slides towards the first deflector 32 under the action of centrifugal force, and stretches and stores energy in the spring 37. The first connecting rod 42 and the second connecting rod 43 rotate as the second deflector 35 moves, keeping the second deflector 35 only moving without rotating. At the same time, the first deflector 32 attracts the second deflector 35, and under the action of centrifugal force and magnetic force, the second deflector 35 contacts and presses the trigger piece 34, causing the trigger piece 34 to be pressed to open the valve of the first backflush nozzle plate 33. The air flow blown out by the first backflush nozzle plate 33 blows towards the main shaft 25 through the ventilation openings on the second backflush nozzle plate 36. When the main shaft 25 stops rotating, the magnetic force of the first deflector 32 on the second deflector 35 is not sufficient to overcome the elastic force of the spring 37. Under the action of the elastic force of the spring 37, the second deflector 35 slides back towards the main shaft 25. During the sliding process of the second deflector 35, the powder and dust attached to the surface of the second rod 28 are scraped off, reducing the influence of the attachment of powder and dust on the transmission. And the closing time of the air inlet pipe 22 on the dust removal tank 5 is later than that of the main shaft motor 24, which can also blow off the powder and dust attached to each component.

[0107] Through the above structural design, the automatic opening of the valve of the first backflush nozzle plate 33 on the first deflector 32 is effectively realized. As the second deflector 35 slides, the attachment of powder and dust on the second rod 25 can be reduced. By setting the diameter of the ventilation opening of the second deflector 35 to a smaller size, the air flow blown out by the first backflush nozzle plate 33 can be better dispersed, and there will be no great hindrance to the movement of dust particles during backflush, improving the backflush effect.
