Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying target powder recovery device with multi-stage filtration capability. Background Technology

[0002] Plasma spraying is a technology for strengthening and modifying material surfaces, enabling substrate surfaces to possess properties such as wear resistance, corrosion resistance, high-temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction, and sealing. Plasma spraying technology uses a plasma arc driven by direct current as a heat source to heat materials such as ceramics, alloys, and metals to a molten or semi-molten state, and then sprays them at high speed onto the pre-treated workpiece surface to form a firmly adhered surface layer.

[0003] Most spray targets have a powder utilization rate of 50-70%. The uncoated powder is drawn into the blower. Most manufacturers cannot produce a single machine that can only produce one type of target because it is too costly and inefficient. Current target spraying equipment cannot classify and recycle the uncoated powder. The powder waste drawn into the blower is a mixture of various materials with varying contents, which means that the powder has no recycling value and results in a waste of powder raw materials. Utility Model Content

[0004] Given that existing biomass pellet filtration systems typically filter biomass pellets using a filter screen, but during the filtration process, some small biomass pellets may get stuck in the mesh of the filter screen, causing the filter screen to become clogged and raw materials to accumulate at the top of the filter screen, thus affecting the filtration efficiency, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-stage filtration spray target powder recovery device, including a recovery platform, a recovery seat at the upper end of the recovery platform, a sorting platform at the upper end of the recovery seat, multiple sets of sorting ports evenly spaced at the upper end of the sorting platform, multiple sets of collection ports corresponding to the sorting ports at the lower end of the recovery seat, multiple sets of sorting components in the inner cavity of the sorting ports, each sorting component including a sorting box inserted into the inner cavity of the sorting port, a first filter screen at the lower end of the sorting box, a collection box inserted into the inner cavity of the collection port, a second filter screen at the lower end of the collection box, a vent hole at the lower end of the recovery seat at the lower end of the second filter screen, a motor on one side of the outer wall of the recovery platform, a ball screw at the output end of the motor, a first connecting plate sleeved on the outer wall of the ball screw, and a connecting pipe fixed on one side of the outer wall of the recovery platform.

[0006] As a preferred embodiment of the multi-stage filtration spray target powder recovery device of this utility model, the sorting box and the collection box are respectively movably inserted into the sorting port and the collection port cavity, and the sorting component further includes a receiving block fixedly disposed in the inner wall of the sorting port, and the sorting box is attached to the receiving block.

[0007] As a preferred embodiment of the multi-stage filtration spray target powder recovery device of this utility model, the sorting component further includes a sealing plate hinged in the inner cavity of the sorting port, an adjusting rod hinged at the lower end of the sealing plate, a sliding sleeve hinged at the lower end of the adjusting rod, a sliding rod movably inserted in the middle of the sliding sleeve, a fixing block fixedly provided at the upper and lower ends of the sliding rod, the fixing block being fixedly connected to the inner wall of the sorting port, and a spring movably sleeved on the outer wall of the lower end of the sliding sleeve on the sliding rod, the upper and lower ends of the spring being fixedly connected to the sliding sleeve and the fixing block, respectively.

[0008] As a preferred embodiment of the multi-stage filtration spray target powder recovery device of this utility model, wherein: the inner wall of the sorting port is fixedly provided with a baffle at the upper end of the sealing plate.

[0009] As a preferred embodiment of the multi-stage filtration spray target powder recovery device of this utility model, the ball screw is rotatably mounted on the upper end of the recovery platform, the first connecting plate has a threaded hole that cooperates with the ball screw, a fixing rod is fixedly mounted on the upper end of the recovery platform on the side opposite to the ball screw, a second connecting plate is movably sleeved on the outer wall of the fixing rod, and both the first connecting plate and the second connecting plate are fixedly connected to the recovery seat.

[0010] In a preferred embodiment of the multi-stage filtration powder recovery device for sprayed targets described in this utility model, the air outlet end of the connecting pipe and the upper surface of the sorting platform are in contact.

[0011] As a preferred embodiment of the multi-stage filtration powder recovery device for sprayed targets described in this utility model, the outer wall of the recovery seat is fixedly provided with two sets of mutually symmetrical mounting blocks, the middle end of the mounting blocks is threaded with bolts, and the outer wall of the sorting table is provided with through holes that cooperate with the bolts.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] In this invention, a fan draws powder into the connecting pipe, and the powder drawn in by the fan is discharged into a sorting box. The powder passes through a first filter screen and enters a collection box. A second filter screen can intercept the powder, and the intercepted powder accumulates in the collection box for collection. A motor is started to drive a ball screw to rotate, and the ball screw drives a first connecting plate to slide along the outer wall of the ball screw. The first connecting plate drives a recycling seat to move, so that another set of sorting ports and the air outlet of the connecting pipe are connected, which can sort and recycle different types of powder.

[0014] 2. In this utility model, when powder waste is injected into the collection box, the air pressure of the blower causes the sealing plate to rotate downwards at a certain angle. The adjusting rod drives the sliding sleeve to slide downwards along the outer wall of the sliding rod and compresses the spring. After the powder waste is injected, the blower is turned off. Under the reverse elastic force of the spring, the sliding sleeve slides upwards along the outer wall of the sliding rod. The adjusting rod pushes the sealing plate to rotate upwards at a certain angle until the sealing plate and the stop block abut against each other. Under the interception effect of the sealing plate, the powder can be prevented from flowing back along the sorting box and spreading outwards from the sorting opening until the powder stabilizes and is collected in the collection box.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Reference Figure 1 and Figure 4This is the first embodiment of the present invention, which provides a multi-stage filtration spray target powder recovery device, including a recovery platform 1. The recovery platform 1 is characterized by: a recovery seat 2 at its upper end, a sorting platform 3 at its upper end, multiple sorting ports 4 evenly spaced at the upper end of the sorting platform 3, multiple collection ports 5 correspondingly located below the sorting ports 4 at the lower end of the recovery seat 2, multiple sorting components 6 within the inner cavity of the sorting ports 4, each sorting component 6 including a sorting box 601 inserted into the inner cavity of the sorting port 4, a first filter screen 602 at the lower end of the sorting box 601, a collection box 7 inserted into the inner cavity of the collection ports 5, a second filter screen 8 at the lower end of the collection box 7, a vent hole 9 at the lower end of the recovery seat 2 below the second filter screen 8, a motor 10 on one side of the outer wall of the recovery platform 1, a ball screw 11 at the output end of the motor 10, a first connecting plate 12 sleeved on the outer wall of the ball screw 11, and a connecting pipe 14 fixedly located on one side of the outer wall of the recovery platform 1.

[0024] The sorting box 601 and the collection box 7 are respectively movably inserted into the inner cavity of the sorting port 4 and the collection port 5. The sorting component 6 also includes a receiving block 603 fixedly disposed in the inner wall of the sorting port 4, and the sorting box 601 is attached to the receiving block 603.

[0025] A stop block 610 is fixedly provided on the inner wall of the classification port 4 at the upper end of the sealing plate 604.

[0026] The ball screw 11 is rotatably mounted on the upper end of the recycling platform 1. The first connecting plate 12 has a threaded hole that mates with the ball screw 11. A fixing rod 17 is fixedly mounted on the upper end of the recycling platform 1 on the side opposite to the ball screw 11. A second connecting plate 13 is movably sleeved on the outer wall of the fixing rod 17. Both the first connecting plate 12 and the second connecting plate 13 are fixedly connected to the recycling seat 2. When the starting motor 10 drives the first connecting plate 12 to move, the second connecting plate 13 slides along the outer wall of the fixing rod 17, which increases the stability of the recycling seat 2 and the sorting platform 3 during movement.

[0027] The air outlet of the connecting pipe 14 is in contact with the upper surface of the sorting table 3.

[0028] The outer wall of the recycling station 2 is fixed with two sets of symmetrical mounting blocks 15. The mounting blocks 15 are threaded with bolts 16 at the middle end. The outer wall of the sorting table 3 is provided with through holes that cooperate with the bolts 16.

[0029] Powder is drawn into the connecting pipe 14 by a fan and discharged into the sorting box 601. The first filter screen 602 can intercept larger particles of impurities, such as unmelted particles and splashes. The powder passes through the first filter screen 602 and enters the collection box 7. The second filter screen 8 can intercept the powder, which accumulates in the collection box 7 for collection. Gas is discharged through the vent 9 at the lower end of the recovery seat 2. When spraying a different target material, the starting motor 10 drives the ball screw 11 to rotate. The ball screw 11 drives the first connecting plate 12 to slide along the outer wall of the ball screw 11. The connecting plate 12 drives the recycling seat 2 to move, so that another set of sorting ports 4 and the air outlet of the connecting pipe 14 are connected. Then, the different types of powder are sorted and recycled according to the above steps. After the powder is collected, the bolt 16 can be unscrewed from the mounting block 15 to separate the recycling seat 2 and the sorting table 3. The sorting box 601 and the collection box 7 can be pulled out from the sorting port 4 and the collection port 5 respectively. Large particles in the sorting box 601 and powder in the collection box 7 can be recycled. Multiple sets of collection boxes 7 can sort and recycle powder of different materials. The recycled powder can be reused after multiple filtrations to avoid waste of raw materials.

[0030] Example 2

[0031] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the sorting component 6 further includes a sealing plate 604 hinged in the inner cavity of the sorting port 4. An adjusting rod 605 is hinged to the lower end of the sealing plate 604. A sliding sleeve 607 is hinged to the lower end of the adjusting rod 605. A sliding rod 608 is movably inserted into the middle of the sliding sleeve 607. A fixing block 606 is fixedly provided at the upper and lower ends of the sliding rod 608. The fixing block 606 is fixedly connected to the inner wall of the sorting port 4. A spring 609 is movably sleeved on the outer wall of the lower end of the sliding sleeve 607. The upper and lower ends of the spring 609 are fixedly connected to the sliding sleeve 607 and the fixing block 606, respectively.

[0032] When the powder waste is injected into the collection box 7, the air pressure of the blower causes the sealing plate 604 to rotate downwards at a certain angle. The adjusting rod 605 drives the sliding sleeve 607 to slide downwards along the outer wall of the sliding rod 608 and compress the spring 609. After the powder waste is injected, the blower is turned off. Under the reverse elastic force of the spring 609, the sliding sleeve 607 slides upwards along the outer wall of the sliding rod 608. The adjusting rod 605 pushes the sealing plate 604 to rotate upwards at a certain angle until the sealing plate 604 and the stop block 610 abut against each other. Under the interception effect of the sealing plate 604, the powder can be prevented from flowing back along the sorting box 601 and spreading outwards towards the sorting port 4 until the powder stabilizes and is collected in the collection box 7.

[0033] The remaining structure is the same as that in Example 1.
