Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology, and in particular relates to a vacuum sand suction machine with shot and sand separation function. Background Technology

[0002] In the surface treatment of metal workpieces such as castings and forgings, shot blasting is often used to remove oxide scale, rust, and adhering sand and other impurities from the workpiece surface. After shot blasting, a large amount of steel shot and sand particles will remain on the workpiece surface, which needs to be cleaned and recycled in a timely manner to ensure the normal operation of subsequent processes and the cleanliness of the working environment.

[0003] Currently, the industry primarily uses vacuum sand suction machines to clean and recycle residual shot and grit mixtures. However, existing vacuum sand suction machines generally only have a single adsorption and recycling function, and cannot effectively separate steel shot and grit particles during the recycling process. The recycled shot and grit mixture needs to be processed separately through specialized separation equipment, which not only increases equipment investment costs and floor space, but also prolongs the production process and reduces work efficiency.

[0004] Therefore, it is necessary to design a vacuum sand suction machine with shot and sand separation function. Utility Model Content

[0019] Example 1 A preferred embodiment of the vacuum sand suction machine with shot and sand separation function provided by this utility model is as follows: Figures 1 to 4As shown: A vacuum sand suction machine with shot and sand separation function includes: a protective frame 1, a collection tank 2 and a separation box 6 fixed on the top of the protective frame 1, a guide plate 14 welded inside the separation box 6, a first screen plate 15 and a second screen plate 16 movably installed inside the separation box 6, and the installation angle of the first screen plate 15 and the second screen plate 16 is 30 degrees, the first screen plate 15 has a plurality of first filter holes 19 inside, the second screen plate 16 has a plurality of second filter holes 17 inside, the aperture of the first filter holes 19 is larger than the aperture of the second filter holes 17, two discharge ports 7 are provided on one side of the separation box 6, a pneumatic valve is installed at the discharge port 7, two transmission rods 12 are installed inside the separation box 6, two eccentric blocks 13 are fixedly sleeved on the outside of the transmission rods 12, a drive assembly 10 is installed on one side of the separation box 6, a dust collector 4 is installed on the top of the collection tank 2, the top of the dust collector 4 is connected to the inside of the separation box 6 through a dust suction pipe 5, and an exhaust pipe 3 is connected to one side of the dust collector 4.

[0020] A limiting plate 20 is welded at the corner of the inner wall of the separation box 6, and a support slide rod 21 is slidably installed inside the limiting plate 20.

[0021] A spring 22 is sleeved on the outer side of the support slide rod 21, and the top of the support slide rod 21 is welded to the top of the first screen plate 15 and the second screen plate 16.

[0022] The drive assembly 10 includes a housing 1001 that is bolted to the outside of the separation box 6, and a first sprocket 1002 and a motor 1003 are rotatably mounted inside the housing 1001.

[0023] One end of the first sprocket 1002 extends into the interior of the separation box 6 and is fixedly connected to one end of a transmission rod 12. One end of the second sprocket 1005 extends into the interior of the separation box 6 and is fixedly connected to one end of another transmission rod 12. A transmission chain 1004 is installed between the first sprocket 1002 and the second sprocket 1005. A motor 1003 is fixed to one side of the housing 1001 by bolts. The output end of the motor 1003 extends into the interior of the housing 1001 and is fixedly connected to one end of the first sprocket 1002.

[0024] In this invention, a negative pressure is generated inside the separation chamber 6 by a negative pressure machine to create a negative pressure. The mixture is then drawn into the separation chamber 6 by the suction pipe 8. Inside the separation chamber 6, the mixture falls onto the surface of the guide plate 14 and is evenly distributed onto the surface of the first screen plate 15. Since the first screen plate 15 has first filter holes 19, the pellets in the mixture can be filtered through these holes. Particles smaller than the diameter of the first filter holes 19 are filtered onto the surface of the second screen plate 16. The second screen plate 16 has second filter holes 17, which can filter fine dust. Simultaneously, the motor 10 is controlled... The rotation of the output end 03 simultaneously drives the first sprocket 1002 and the second sprocket 1005 to rotate, and also drives the two transmission rods 12 to rotate. Since the outer side of the transmission rod 12 is fixedly fitted with an eccentric block 13, the rotation of the transmission rod 12 can drive the eccentric block 13 to frequently contact the bottom of the first screen plate 15 and the second screen plate 16, thereby causing the first screen plate 15 and the second screen plate 16 to vibrate inside the separation box 6, thus fully screening and filtering the material that falls on the surface of the first screen plate 15 and the second screen plate 16. This device can separate the pellets and sand in the pellet-sand mixture without the need for additional special separation equipment, reducing equipment investment costs and floor space, simplifying the production process, and improving work efficiency.

[0025] The collection tank 2 is connected to the interior of the dust collector 4, and a cleaning port 11 is provided on one side of the collection tank 2.

[0026] The top of the separation box 6 is connected to the suction pipe 8 via a flange, and the suction pipe 8 is connected to the interior of the separation box 6. Multiple bases 9 are welded to the bottom of the protective frame 1.

[0027] Two discharge guide plates 18 are welded to one side of the interior of the separation box 6, and the two discharge guide plates 18 are used in conjunction with the first screen plate 15 and the second screen plate 16 respectively.

[0028] In this invention, the screened material falls onto the surface of the discharge guide plate 18 through the surface of the first screen plate 15 and the second screen plate 16, and is then discharged into the separation box 6 through the corresponding discharge port 7. The filtered fine dust is sucked into the dust collector 4 through the suction pipe 5, thereby settling the particulate matter in the air and collecting it inside the collection tank 2. Then the gas is discharged through the exhaust pipe 3. Since a cleaning port 11 is provided on one side of the collection tank 2, the waste collected inside the collection tank 2 can be processed by opening the cleaning port 11.

[0029] Working principle: The negative pressure machine creates a negative pressure environment inside the separation chamber 6. The shot and sand mixture is sucked into the separation chamber 6 through the suction pipe 8. After being guided by the guide plate 14, it is evenly dispersed onto the surface of the first screen plate 15. The motor 1003 starts, and the output end drives the first sprocket 1002 inside the outer casing 1001 to rotate. Through the transmission chain 1004, it drives the second sprocket 1005 to rotate synchronously, which in turn drives the two transmission rods 12 to rotate. The eccentric block 13 on the outside of the transmission rod 12 rotates with the shaft and frequently hits the bottom of the first screen plate 15 and the second screen plate 16, causing the screen plates to vibrate under the action of the support slide rod 21 and the spring 22. The first screen plate 15... The first filter hole 19 has a larger aperture, separating larger steel shot particles. The steel shot slides down the inclined surface of the screen plate to the corresponding discharge guide plate 18 and is discharged through the discharge port 7. Sand and dust particles with a diameter smaller than the first filter hole 19 fall to the second screen plate 16. The second filter hole 17 of the second screen plate 16 has a smaller aperture, separating sand particles. The sand particles are discharged through another set of discharge guide plates 18 and discharge port 7. Fine dust is sucked into the dust collector 4 through the suction pipe 5, and after settling, it is collected in the collection tank 2. Clean gas is discharged through the exhaust pipe 3. The cleaning port 11 is opened periodically to clean the dust in the collection tank 2, completing the entire adsorption, separation, and collection process.
