Description

Technical Field

[0001] The utility model relates to a feeding machine, in particular to a vacuum feeding machine for powder processing. Background Art

[0002] A vacuum feeder uses a vacuum pump to evacuate air, making the inlet of the suction nozzle and the entire system in a certain vacuum state. The powder and granular materials are sucked into the nozzle along with the outside air to form a material air flow, which reaches the hopper through the suction pipe, and air-material separation is carried out in the hopper.

[0003] When using a vacuum feeding machine for vacuum feeding of powder materials, large-particle powder materials are filtered by the filter element to ensure that only small-particle powder materials can be discharged through the vacuum system, while the large-particle powder materials remain in the system. After long-term use, the mesh holes on the filter element are easily blocked by the powder materials. When the mesh holes of the filter element are blocked, the resistance of air flow will increase significantly, thereby reducing the suction capacity of the system and naturally reducing the feeding efficiency of the entire system.

[0004] Therefore, it is necessary to design a vacuum feeding machine for powder processing that can clean the filter element. Summary of the Utility Model

Detailed implementation manners

[0020] The preferred technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] Example 1: A vacuum feeding machine for powder processing, as shown in Figures 1 - 3 the figure, includes a support frame 1, a feeding shell 2 and a vacuum pump 3. The feeding shell 2 is fixedly connected to the top of the support frame 1, and the vacuum pump 3 is embedded and installed on the upper part of the feeding shell 2. It also includes a filter barrel 5, a flap 6, a pull handle 7, a feeding plate 8, a pulse backflush assembly 4, a discharge hopper 9 and a control ball valve 10. The input end of the vacuum pump 3 is installed with a filter barrel 5 by means of bolt connection. The filter barrel 5 is located inside the feeding shell 2. The feeding plate 8 is installed inside the feeding shell 2 by means of bolt connection. The feeding plate 8 is located below the filter barrel 5. A feeding port is opened on the front side of the upper part of the feeding shell 2. The pulse backflush assembly 4 is installed on the top of the feeding shell 2. The pulse backflush assembly 4 is located above the filter barrel 5. The pulse backflush assembly 4 is composed of an air compressor, a pulse valve and a spray pipe. The air compressor is used to provide high-pressure air. The pulse valve controls the release of compressed air. The spray pipe is used to blow air onto the filter barrel 5. The flap 6 is rotatably arranged on the front side of the feeding shell 2. An observation plate 23 is installed on the flap 6. By observing through the observation plate 23, the feeding situation of the powder in the feeding shell 2 can be observed, which is convenient for taking corresponding measures in time. The flap 6 rotates to close the feeding port. The discharge hopper 9 is installed at the bottom of the feeding shell 2 by means of bolt connection. The control ball valve 10 is installed at the lower part of the discharge hopper 9. A pull handle 7 is installed on the side of the flap 6 away from the feeding plate 8. An anti-slip sleeve 22 is sleeved on the pull handle 7. The anti-slip sleeve 22 is used to increase the friction between the hand and the pull handle 7.

[0022] When the powder material needs to be fed, first unpack the material bag, then hold the pull handle 7 tightly and turn the flap 6 upwards to open the discharge shell 2. Subsequently, place the unpacked material on the discharge plate 8, turn the flap 6 downwards to close the discharge shell 2. Then start the vacuum pump 3 to make the filter barrel 5 in a vacuum state. The material enters the vacuum pump 3 through the filter barrel 5 along with the external air flow entering through the control ball valve 10, and is then discharged from the output end of the vacuum pump 3, thus realizing the feeding operation. The filter barrel 5 filters the material to prevent larger particle-sized materials from entering the vacuum pump 3. After the powder material finishes feeding, turn off the vacuum pump 3 and the control ball valve 10, and then start the pulse back-blowing assembly 4. The pulse back-blowing assembly 4 compresses air, and the high-flow pulse blowing pressure blows back the filter element. The filter barrel reduces or removes the adsorbed material on the surface to prevent the filter barrel 5 from being blocked after the powder material is transported. The blown-off powder falls downwards through the discharge plate 8 until it falls into the lower hopper 9. When the powder material accumulates to a certain extent in the lower hopper 9, open the lower hopper 9 through the control ball valve 10 to discharge the powder material in the lower hopper 9.

[0023] Embodiment 2: On the basis of Embodiment 1, referring to Figure 3 and Figure 4 As shown, it further includes a limit disk 11, a connecting seat 12 and a telescopic rod 13. Limit disks 11 are installed on the left and right sides at the rear of the flap 6 by means of bolt connection. Connecting seats 12 are rotatably arranged on both sides at the front of the discharge shell 2. A telescopic rod 13 is slidably arranged in the connecting seat 12, and the telescopic rod 13 is rotatably connected to the limit disk 11.

[0024] When holding the pull handle 7 tightly and turning the flap 6 upwards to open the discharge shell 2, the flap 6 drives the telescopic rod 13 to stretch upwards through the limit disk 11. At the same time, the telescopic rod 13 drives the connecting seat 12 to rotate, so that the telescopic rod 13 and the connecting seat 12 support the flap 6.

[0025] Referring to Figure 1 and Figure 3 As shown, it further includes a support seat 14, a sieve plate 15, a placement rack 1501 and a vibration motor 16. A support seat 14 is fixedly connected to the front side outside the discharge shell 2. A vibration motor 16 is installed on the support seat 14 by means of bolt connection. A placement rack 1501 is fixedly connected to the middle inside the discharge shell 2 by means of welding. The placement rack 1501 is provided with a sieve plate 15, and the sieve plate 15 slides up and down inside the discharge shell 2. The output shaft of the vibration motor 16 penetrates the discharge shell 2 and is connected to the sieve plate 15.

[0026] When the blown-off powder falls downwards, the powder falls on the sieve plate 15. Then start the vibration motor 16, and the vibration motor 16 drives the sieve plate 15 to move up and down to screen the powder. The powder with larger particle size remains on the sieve plate 15, and the powder with smaller particle size falls downwards into the lower hopper 9.

[0027] Referring to Figure 3 andFigure 5 As shown, it further includes a discharge pipe 17, a driving motor 18, a spiral blade 19 and a connecting pipe 20. The lower part of the control ball valve 10 is connected and communicated with the discharge pipe 17. Transparent glasses 21 are embedded on both the left and right sides of the discharge pipe 17. The situation of the powder material in the discharge pipe 17 is observed through the transparent glasses 21 to avoid blockage of the discharge pipe 17. The driving motor 18 is installed at the rear side of the discharge pipe 17. A spiral blade 19 is rotatably arranged inside the discharge pipe 17. The output shaft of the driving motor 18 penetrates through the discharge pipe 17 and is fixedly connected with the spiral blade 19. A connecting pipe 20 is connected and communicated with one side of the upper part of the discharge pipe 17 far away from the driving motor 18.

[0028] When the powder material accumulates to a certain extent in the hopper 9, the control ball valve 10 opens the hopper 9 to discharge the powder material in the hopper 9 into the discharge pipe 17. Subsequently, the motor is started, and the output shaft of the motor drives the spiral blade 19 to rotate, so that the powder material moves forward for transportation, and then is transported to the next process through the connecting pipe 20.
