Description

Technical Field

[0001] The present invention relates to the technical field of powder conveying equipment, and more specifically, to an intelligent powder conveyor. Background Art

[0002] Powder is often used as raw material in product production. How to transport powder to the workstation and ensure the accuracy of the transport volume is an urgent problem to be solved in powder transportation. Powder transportation is now widely used in the transportation of light dry powder such as metal powder, coal powder, and chemical industry. Common transportation methods include pneumatic conveying, pipe chain conveying, etc.

[0003] In the prior art, for example, the utility model patent with application number CN202322248073.X discloses a powder metering and conveying device, including a main body, a back frame is provided at the front end of the main body, a fixing clamp is provided at one end of the main body, a stirring mechanism is installed in the middle of the fixing clamp, a feed port is provided 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 is provided on the outer side of the lower end of the metering mechanism, and a bracket is provided at the lower end of the conveying mechanism. The utility model is installed in the middle of the inner side of the fixing clamp by a stirring drum.

[0078] Furthermore, a vibrating distributor 9 is provided between the feeder 7 and the metering tank 8 of the first metering and discharging unit 2 .

[0079] The vibrating distributor breaks up the powder by mechanical vibration, so that the powder can be evenly, regularly and continuously transported from the feeder 7 to the metering tank 8.

[0080] Furthermore, a second discharging screw 10 is provided between the feeder 7 and the metering tank 8 of the second metering discharging unit 3. The second discharging screw 10 forms a spiral motion track in the discharging pipe, and transports the powder along the pipe to the metering tank 8, thereby improving the continuity and uniformity of the discharging process.

[0089] Embodiment 2:

[0090] like Figure 5 , 6 As shown, based on the above embodiment 1, the dust removal tank 5 includes:

[0091] The feed pipe 21, the air inlet pipe 22 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 pipe 5 and is located on the side away from the discharge pipe 23, and the air inlet pipe 22 is connected to the dust removal fan 4 of the feeding station;

[0092] A spindle motor 24, which is disposed at the top of the dust removal tank 21;

[0093] The main shaft 25 is rotatably connected to the top of the inner wall of the dust removal tank 5 and is connected to the output end of the main shaft motor 24. The 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;

[0094] A plurality of dispersion rod units 26 are connected to the main shaft 25 at intervals to break up the powder.

[0095] The working principle and beneficial effects of the above technical solution are:

[0096] When the dust removal tank 5 is in use, the powder is added to the dust removal tank 5 from the feed pipe 21, and the dust removal fan 4 of the feeding station conveys airflow into the dust removal tank 5 through the air inlet pipe 22, and the spindle motor 24 is started to drive the spindle 25 to rotate, and the dispersion rod unit 26 on the spindle 25 rotates accordingly to break up the added powder; under the action of centrifugal force, the dust and particulate matter mixed in the powder moves toward the inner wall of the dust removal tank 5 due to its large weight, and after colliding with the inner wall of the dust removal tank 5, it is discharged from the dust removal pipe at the bottom; the powder is light in weight, and after being broken up, it flows upward under the action of the airflow and is discharged through the discharge pipe 23. Through the above-mentioned structural design, a dispersion rod unit 26 is set in the dust removal tank 5, and the powder is broken up by the high-speed rotation of the dispersion rod 26, thereby reducing the agglomeration of the powder, facilitating the transportation of the powder, and improving the dust removal effect of the powder; and under the joint action of the airflow power and the rotating centrifugal force, the powder and dust particles are quickly separated.

[0097] Embodiment 3:

[0098] like Figure 7 , 8 As shown, based on the above embodiment 2, the dispersion rod unit 26 includes:

[0099] A first rod body 27, one end of which is connected to the main shaft 25;

[0100] A second rod 28, the second rod 27 is connected to the other end of the first rod 27, the diameter of the second rod 27 is smaller than the diameter of the first rod 27, and an air flow channel 29 connected to the main air inlet channel is provided at the center of the first rod 27 and the second rod 28;

[0101] An airflow nozzle 31, which is connected to the end of the second rod 28, and an air inlet end of the airflow nozzle 31 is connected to the airflow channel 29;

[0102] A first air guide cover 32, the first air guide cover 32 is connected to the second rod body 28, the first air guide cover 32 is arranged in an arc shape, and is bent toward the first rod body 27;

[0103] A first recoil nozzle plate 33, wherein a plurality of first recoil nozzle plates 33 are connected to a side of the first air guide cover 32 close to the first rod body 27, the first recoil nozzle plates 33 are connected to the air flow channel 29, and a plurality of recoil ports are arranged on the first recoil nozzle plates 33;

[0104] The trigger plate 34 is connected to the center of the first air guide cover 32 . After the trigger plate 34 is subjected to a preset pressure, the air inlet valve of the first recoil nozzle plate 33 is opened.

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

[0106] When the dispersion rod unit 26 is in use, the dust removal fan 4 of the feeding station conveys the airflow to the main air inlet channel of the main shaft 25, and the airflow flows from the main air inlet channel into the airflow channel 29 of the first rod body 27 and the second rod body 28, and then flows into the airflow nozzle 31, and is ejected outward through the airflow nozzle 31. The above structural design solves the problem that when gas is introduced from the lower part of the dust removal pipe 21, an airflow vortex is formed when the dispersion rod unit 26 rotates at a high speed, resulting in the powder falling between the dispersion rod unit 26 and the inner wall of the dust removal pipe 21 cannot be effectively separated; the airflow nozzle 31 sprays airflow as a supplement, which can quickly blow away the powder falling between the dispersion rod unit 26 and the inner wall of the dust removal pipe 21, and flow it upward, reducing the loss of powder during the dust removal process.

[0107] By setting the first recoil nozzle plate 33, when the air inlet valve of the first recoil nozzle plate 33 is opened, the first recoil nozzle plate 33 sprays toward the main shaft 25 through the recoil port, colliding with the powder and dust particles moving outward under the action of centrifugal force, further improving the dispersion effect, increasing the disturbance of the air flow, and at the same time cleaning the inner side of the first air guide cover 32 and the surfaces of the first rod body 27 and the second rod body 28 to reduce dust adhesion.

[0108] Embodiment 4:

[0109] like Figure 7 , 8 As shown, based on the above embodiment 1, the dispersion rod unit 26 further includes:

[0110] A second air guide cover 35, wherein a slip ring 38 is disposed at the center of the second air guide cover 35, and the slip ring 38 is slidably connected to the second rod body 28, and the second air guide cover 35 is disposed in an arc shape and is adapted to be disposed with the first air guide cover 32; the first air guide cover 32 and the second air guide cover 35 are magnetic and attract each other;

[0111] A second recoil nozzle plate 36, wherein a plurality of second recoil nozzle plates 36 are connected to the second air guide cover 35, and a plurality of vents are provided on the second recoil nozzle plate 36, and positions of the vents on the second recoil nozzle plate 36 correspond to positions of the recoil ports on the first recoil nozzle plate 33;

[0112] A spring 37, wherein the spring 37 is sleeved on the second rod 28, and two ends of the spring 37 are respectively connected to the first rod 27 and the slip ring 38;

[0113] Slide rails 39, two slide rails 39 are symmetrically arranged on the first rod body 27, and a slider 41 is slidably arranged on the slide rails 39;

[0114] A first connecting rod 42, one end of the first connecting rod 41 is hinged to the slider 41;

[0115] A second connecting rod 43, both ends of which are hinged to the slip ring 38 and the other end of the first connecting rod 42 respectively;

[0116] A sealing cover, which is connected to the first rod body 27 and the first connecting rod 42, and is used to isolate the inside of the track of the slide rail 39 from the powder;

[0117] The working principle and beneficial effects of the above technical solution are:

[0118] The second air guide cover 35 is arranged on the second rod body 28. When the main shaft 25 rotates at a high speed, the second air guide cover 35 slides toward the first air guide cover 32 under the action of centrifugal force, and stretches the spring 37 to store energy. The first connecting rod 42 and the second connecting rod 43 rotate along with the movement of the second air guide cover 35, so that the second air guide cover 35 only moves but does not rotate. At the same time, the first air guide cover 32 attracts the second air guide cover 35. Under the action of centrifugal force and magnetic force, the second air guide cover 35 contacts the first air guide cover 32 and squeezes the trigger plate 34, so that the trigger plate 34 is pressurized to open the valve of the first recoil nozzle plate 33. The airflow blown out by the first recoil nozzle plate 33 is sprayed toward the main shaft 25 through the vent on the second recoil nozzle plate 36. When the spindle 25 stops rotating, the magnetic force of the first air guide cover 32 on the second air guide cover 35 is not sufficient to overcome the elastic force of the spring 37. Under the elastic force of the spring 37, the second air guide cover 35 slides toward the spindle 25 and resets. During the sliding process of the second air guide cover 35, the powder and dust attached to the surface of the second rod body 28 are scraped off, reducing the influence of the powder and dust adhesion on the transmission. In addition, the closing time of the air inlet pipe 22 on the dust removal tank 5 is later than that of the spindle motor 24, so that the powder and dust attached to each component can also be blown off.

[0119] Through the above-mentioned structural design, the automatic opening of the valve of the first recoil nozzle plate 33 on the first air guide cover 32 is effectively realized; as the second air guide cover 35 slides, the adhesion of powder dust on the second rod body 25 can be reduced; the ventilation port diameter of the second air guide cover 35 is set to a smaller size, which can better disperse the airflow blown out of the first recoil nozzle plate 33, and will not cause a large obstruction to the movement of dust particles during recoil, thereby improving the recoil effect.

[0120] Embodiment 5:

[0121] like Figure 9-12 As shown, based on the above-mentioned embodiment 4, the dispersion rod unit 26 further includes a heat protection unit, and the heat protection unit includes:

[0122] A protective ring 51, wherein two protective rings 51 are provided, and are respectively provided at the end of the slip ring 38 and the end of the first rod body 27, and the two protective rings 51 are respectively connected to the two ends of the spring 37;

[0123] The heat induction cavity 52 is configured as an annular cavity and is disposed in the slip ring 38 and the first rod body 27. The heat induction cavity 52 contains thermal expansion gas;

[0124] The piston plate 53 is slidably connected to the heat sensing chamber 52. An elastic reset member 54 is connected between the end of the piston plate 53 and the inner wall of the heat sensing chamber 52. The piston plate 53 extends out of the slip ring 38 and the first rod body 27 and is connected to the protective ring 51.

[0125] A transmission cavity 55, wherein a plurality of transmission cavities 55 are evenly arranged in the slip ring 38, and the transmission cavity 55 is communicated with the interior of the slip ring 38;

[0126] The locking plate 56 is slidably connected to the transmission cavity 55. The inner side of the locking plate 56 is provided with an arc surface which is concentric with the slip ring 28, and a friction pad is connected to the arc surface; the outer side of the locking plate 56 is provided with an inclined surface; a spring is provided between the end of the locking plate 56 and the outer side surface of the transmission cavity 55;

[0127] The arc groove 57 is arranged on a side of the transmission cavity 55 close to the protective ring 51, and the arc groove 57 penetrates the slip ring 38;

[0128] The sliding post 58 is slidably connected in the arc groove 57 , and the sliding post 58 is connected to the protective ring 51 on the slip ring 38 , and the sliding post 58 abuts against the inclined surface of the locking plate 56 .

[0129] The working principle and beneficial effects of the above technical solution are:

[0130] When the second air guide cover 35 slides on the second rod body 25, due to frequent sliding and collision with powder and dust, the temperature of the slip ring 38 and the rod body will rise, causing the surface of the structural parts to heat up and even affect deformation. By setting a thermal protection unit, when the temperature of the slip ring 38 and the rod body rises, the heat is transferred to the protective ring 51, causing the volume of the thermal expansion gas in the heat sensing chamber 52 to expand, pushing the piston plate 53 to slide along the inner wall of the heat sensing chamber 52, and compressing the elastic reset member 54 to store energy; when the piston plate 53 moves, it drives the protective ring 51 to rotate, and the protective ring 51 on the slip ring 38 drives the sliding column 28 to rotate and slide along the arc groove 57; the flower rent 58 squeezes the inclined surface of the locking plate 56, so that the friction pad on the arc surface of the locking plate 56 moves out of the transmission cavity 55 and squeezes on the second rod body 28, and the slip ring 38 and the second air guide cover 35 are locked and limited under the action of friction, and the slip ring 38 and the rod body no longer slide relative to each other, reducing heat generation. When the temperature of the slip ring 38 and the rod body decreases, the volume of the thermally expanded gas in the heat sensing chamber 52 shrinks, and the piston plate 53 rotates and resets under the action of the elastic reset member 54, so that the protective ring 51 rotates and resets, and the locking plate 56 moves outward under the action of the spring and separates from the second rod body 28, and the slip ring 38 can move freely.

[0131] Through the above-mentioned structural design, the heat protection of the dispersion rod unit 26 is effectively achieved. Under high temperature conditions, the second air guide cover 35 is locked to reduce the friction heat between the slip ring 38 and the rod body, prevent excessive heat, and avoid the problem of bending and deformation of structural parts caused by frequent collisions during powder dust removal, thereby improving the reliability of the dispersion rod unit 26.
