Detailed Embodiment
[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.
[0029] Embodiment 1
[0030] Reference Figures 1 to 3 , a particle powder separation and recovery device, including a tank body 1. A first plate body 11 and a second plate body 12 are arranged in the tank body 1. A first sieve section 111 and a second sieve section 121 are respectively arranged on the first plate body 11 and the second plate body 12; the first sieve section 111 and the second sieve section 121 are arranged staggered in the vertical direction;
[0031] A first channel 13 is formed between the first plate body 11 and the second plate body 12 for the mixed material of particles and powder to roll and fall along the first sieve section 111 and the second sieve section 121; a second channel 14 for outputting the powder sieved by the first sieve section 111 is formed between the first plate body 11 and the tank body 1; a third channel 15 for outputting the powder sieved by the second sieve section 121 is formed between the second plate body 12 and the tank body 1;
[0032] The tank body 1 is provided with a feed pipe 3. The bottom of the tank body 1 is respectively provided with a first discharge port 16 communicated with the first channel 13, a second discharge port 17 communicated with the second channel 14, and a third discharge port 18 communicated with the third channel 15.
[0033] In this design, the mixed material of particles and powder is input into the tank body 1 from the feed pipe 3. Among them, the mixed material of particles and powder can fall along the first channel 13 under the action of its own weight, or under the action of a peripheral conveying mechanism, the mixed material of particles and powder is input into the tank body 1 from the feed pipe 3 by a certain wind force. As the mixed material of particles and powder falls along the first channel 13, the mixed material of particles and powder will first contact the first sieve section 111. The first sieve section 111 performs the first screening on the mixed material of particles and powder. The sieved powder will enter the second channel 14, while the mixed material of particles and powder on the sieve will continue to fall along the first channel 13 until it contacts the second sieve section 121. The second sieve section 121 performs the second screening on the mixed material of particles and powder. The sieved powder will enter the third channel 15, and the particles on the sieve will continue to fall along the first channel 13 until they are discharged from the first discharge port 16; while the powder entering the second channel 14 and the third channel 15 will be discharged from the second channel 14 and the third channel 15.
[0034] In this way, not only can the mixed material of particles and powder be tumbled and screened multiple times, but also the powder screened through the first screening section 111, the powder screened through the second screening section 121, and the particles on the screens of the first screening section 111 and the second screening section 121 are respectively output from the first discharge port 16, the second discharge port 17, and the third discharge port 18 at the bottom of the tank body 1. This structure is not only simple, but also the output positions are concentrated at the bottom of the tank body 1, reducing the lateral space occupation and improving the space utilization rate.
[0035] In a preferred embodiment, the first screening section 111 is of a V-shaped structure, the open end of the first screening section 111 faces the inner wall of the tank body 1, and the top surface of the first screening section 111 is provided with first screening holes 1111;
[0036] The second screening section 121 is of a V-shaped structure, the open end of the second screening section 121 faces the inner wall of the tank body 1, and the top surface of the second screening section 121 is provided with second screening holes 1211.
[0037] In other embodiments, the first screening section 111 can be of an isosceles trapezoid structure, and the second screening section 121 can also be of an isosceles trapezoid structure.
[0038] Because the isosceles trapezoid structure is similar to the V-shaped structure and can both provide two inclined surfaces, and the inclined surfaces are in opposite directions. Therefore, after the mixed material of particles and powder is screened through the first screening holes 1111, the mixed material of particles and powder on the screen can continue to fall in the first channel 13 along the inclined top surface, while the screened powder can move along the inclined bottom surface to the second channel 14 and fall. And after being screened through the second screening holes 1211, the particles on the screen can continue to fall in the first channel 13 along the inclined top surface, and the screened powder can move along the inclined bottom surface to the third channel 15 and fall, realizing the separation and recovery of particles and powder.
[0039] Furthermore, the first screening section 111 is located at the top end of the first plate body 11, and the upper end of the first screening section 111 is connected to the inner wall of the tank body 1; the second screening section 121 is located at the top end of the second plate body 12, and the upper end of the second screening section 121 is connected to the inner wall of the tank body 1.
[0040] With this design, the first screening section 111 is closer to the feed pipe 3, and the mixed material of particles and powder can be screened when it is input from the feed pipe 3 into the tank body 1. Moreover, the first plate body 11 can be longer and can accommodate more mixed material of particles and powder. Similarly, connecting the upper end of the second screening section 121 to the inner wall of the tank body 1 can provide a larger falling space for the mixed material of particles and powder on the screen to fall for secondary screening.
[0041] As a further optimization of this embodiment, a third sieve section 112 is also provided on the first plate body 11 and is located below the first sieve section 111. The second sieve section 121 is located between the first sieve section 111 and the third sieve section 112. The mixed material of particles and powder sequentially passes through the first sieve section 111, the second sieve section 121, and the third sieve section 112 in the first channel 13. The powder sieved by the third sieve section 112 enters the second channel 14, and the particles on the sieve are output from the first discharge port 16 along the first channel 13.
[0042] By adding the third sieve section 112, when the mixed material of particles and powder falls, it can be sieved multiple times through the first sieve section 111, the second sieve section 121, and the third sieve section 112. Of course, it is not limited to three times of sieving. The operator can add subsequent sieve sections according to the actual processing situation, so that the mixed material of particles and powder can be tumbled more times when falling for sieving.
[0043] Further, the third sieve section 112 is an inclined bent portion, and third sieve holes 1121 are provided on the bent portion. In actual work, because the third sieve section 112 is located on the first plate body 11, the powder sieved by the third sieve holes 1121 will enter the second channel 14. Since the third sieve section 112 is already the last sieve section in this embodiment, the third sieve section 112 is set as an inclined bent portion. In other embodiments, if the third sieve section 112 is not the last sieve section, then the third sieve section 112 can also be set to a structure similar to that of the first sieve section 111 and the second sieve section 121, so that the particles on the sieve continue to fall along the first channel 13.
[0044] In this embodiment, a blower 2 is provided at the top of the tank body 1, and the blower 2 is used to introduce cold air into the tank body 1. By providing the blower 2 at the top of the tank body 1, it can not only cool the mixed material of particles and powder entering the tank body 1, but also provide the falling power for the mixed material of particles and powder, avoiding the mixed material of particles and powder from staying on the first plate body 11 or the second plate body 12.
[0045] More preferably, the tank body 1 is a tank body 1 with a cubic structure, and the top of the tank body 1 is a trapezoidal structure. The feed pipe 3 is located at the waist of the trapezoidal structure. In actual use, because the blower 2 needs to be installed at the top of the tank body 1, if the feed pipe 3 is connected to the side of the tank body 1, there will be a situation where the mixed material of particles and powder directly crosses the first sieve section 111 when entering the pipe body. By setting the feed pipe 3 at the waist of the trapezoidal structure, the axis of the feed pipe 3 and the top surface of the first sieve section 111 are preferably in a vertical state. When the mixed material of particles and powder is input by external wind force, the mixed material of particles and powder can be accurately hit on the first sieve section 111.
[0046] In this embodiment, a bracket 4 for supporting the tank body 1 is further provided on the outer side surface of the tank body 1. The bracket 4 can make the first discharge port 16, the second discharge port 17, and the third discharge port 18 in a suspended state, and an operator can set a collection pipe below the corresponding discharge port or convey it to other processes through a pipeline.
[0047] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements or modifications can be made, and these improvements or modifications should also be regarded as the protection scope of the present application.
