It is a cold processing process. It is used to improve the mechanical strength, wear resistance, fatigue resistance and corrosion resistance of parts. In the foundry industry, when surface treatment is performed on castings, sand shots of a certain diameter are often used to spray the casting surface with high pressure. Due to the effect of high pressure, the sand shots are sprayed on the surface to produce broken sand shots. After the broken shots and dust are mixed, the surface treatment of the casting will not be thorough, which will have an adverse effect on the next sand blasting operation. The shot ash separator can be used to separate the complete sand shots and broken shots, so that the sand shots can be reused and save raw materials.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 5 As shown, an embodiment of the utility model provides a pellet ash separator, which includes a shell 10, a rotating plate 20, and a driving member 30. The shell 10 has a feed port 11, an air inlet 12, an air outlet 13, a whole pellet chamber 14, and a residue chamber that are connected to each other. The air inlet 12 and the air outlet 13 are arranged on the side wall of the shell 10 along a lateral interval, the whole pellet chamber 14 and the residue chamber are arranged along a lateral interval, the air inlet 12 and the air outlet 13 are located above the whole pellet chamber 14 and the residue chamber, and the feed port 11 is located above the air inlet 12 and the air outlet 13; the rotating plate 20 is rotatably arranged at the feed port 11 along its longitudinal axis, and the rotating plate 20 has a dredging position for opening the feed port 11 and a unloading position that is gap-matched with the feed port 11; the driving member 30 is arranged on the shell 10, and the driving member 30 is connected to the rotating plate 20 so that the rotating plate 20 can switch between the dredging position and the unloading position.

[0030] The technical solution of the utility model is applied, and the pellet-ash separator includes a housing 10, a rotating plate 20, and a driving member 30. The driving member 30 is used to drive the rotating plate 20 to rotate to the unloading position, so that the rotating plate 20 and the feed port 11 are gap-matched, so that the pellets fall from the gap of the feed port 11. In the process of the pellets falling, the compressed air entering from the air inlet 12 is used to blow the pellets, separate the whole pellets and the broken pellets, and make the whole pellets fall into the whole pellet cavity 14, and make the broken pellets fall into the residue cavity. When the feed port 11 is blocked by large pieces of slag, the driving member 30 is used to drive the rotating plate 20 to rotate to the unblocking position, and the rotating plate 20 opens the feed port 11, and the large pieces of slag fall with the pellets, so as not to block the feed port 11, so that the pellets can be separated normally.

[0031] When the rotating plate 20 is at the unloading position, the shot can fall from the gap between the feed port 11 and the rotating plate 20 and form a sand curtain. Under the action of the shot's own gravity and wind force, the complete steel shot enters the whole shot cavity 14, and the broken shot falls into the residue cavity.

[0032] In this embodiment, in the horizontal projection plane, the rotating plate 20 is located above the whole pill cavity 14. The whole pill cavity 14 is arranged close to the air inlet 12.

[0033] like Figure 3 and Figure 5As shown, the pellet ash separator further includes a guide plate 40, which is rotatably arranged at the feed port 11 along its longitudinal axis. The guide plate 40 has a guiding position for guiding materials and a dropping position with clearance fit with the rotating plate 20. When the rotating plate 20 is at the dredging position, the guide plate 40 is at the guiding position. When the rotating plate 20 is at the dropping position, the guide plate 40 is at the dropping position. When the guide plate 40 rotates from the dropping position to the guiding position, the lower end of the guide plate 40 rotates toward the direction close to the pellet cavity 14. When the guide plate is at the guiding position, large pieces of slag can be guided to fall into the pellet cavity 14.

[0034] In this embodiment, the upper end of the rotating plate 20 is located above the guide plate 40, and the lower end of the guide plate 40 is located below the rotating plate 20, and the size of the rotating plate 20 in the vertical direction is larger than the size of the guide plate 40. When the rotating plate 20 rotates from the unloading position to the dredging position, the distance between the lower end of the rotating plate 20 and the lower end of the guide plate 40 increases.

[0035] like Figure 2 and Figure 4 As shown, the driving member 30 is drivingly connected to the guide plate 40 so that the guide plate 40 switches between the guiding position and the blanking position. With the above structure, the rotation of the rotating plate 20 and the guide plate 40 can be realized by using one driving member 30, which has the advantage of a simple driving structure.

[0036] like Figure 2 As shown, the driving member 30 includes a retractable telescopic member 31 and a transmission assembly 32, the telescopic member 31 is drivingly connected to the transmission assembly 32, and the transmission assembly 32 is drivingly connected to the rotating plate 20 and the guide plate 40 respectively, so as to rotate the rotating plate 20 and the guide plate 40. The telescopic function of the telescopic member 31 can drive the transmission assembly 32 to move, and then the transmission assembly 32 can drive the rotating plate 20 and the guide plate 40 to rotate.

[0037] In this embodiment, the telescopic member 31 is a cylinder, a cylinder body of the cylinder is fixed on the housing 10 , a push rod of the cylinder is movably disposed in the cylinder body and is connected to the transmission assembly 32 .

The rotating shaft 321 is longitudinally penetrated in the middle of the first connecting rod 323, the rotating plate 20 is fixedly connected with the rotating shaft 321, the second connecting rod 324 is hinged with the third connecting rod 325, the guide shaft 322 is longitudinally penetrated in the third connecting rod 325, and the guide shaft 322 is fixedly connected with the guide plate 40. The transmission assembly 32 adopting the above structure has the advantages of simple structure and easy operation.

[0039] Specifically, when the push rod of the cylinder retracts, it drives the first connecting rod 323 to rotate clockwise around the rotating shaft 321, and the rotating shaft 321 rotates accordingly and drives the rotating plate 20 to rotate. The first connecting rod 323 drives the upper end of the second connecting rod 324 to move upward, and the second connecting rod 324 drives the third connecting rod 325 to rotate clockwise around the guide shaft 322, and the third connecting rod 325 drives the guide shaft 322 to rotate clockwise, and the guide shaft 322 drives the guide plate 40 to rotate.

[0042] The detection member 50 is a level meter, which is arranged in the whole pill cavity 14. The level meter can be used to continuously detect the height of the pills, and generate a detection signal when the height does not change.

[0043] like Figure 3As shown, a first baffle 17 extending vertically and a second baffle 18 extending horizontally are arranged in the shell 10. The first baffle 17, the second baffle 18 and the inner wall of the shell 10 together form a feed channel. The upper end of the feed channel is arranged on the top wall of the shell 10, and the lower end of the feed channel forms a feed port 11. When the rotating plate 20 is located at the unloading position, the rotating plate 20 is vertically covered at the feed port 11, and the guide plate 40 is vertically arranged below the feed port 11. The rotating plate 20 and the feed port 11 and the guide plate 40 are all clearance-matched. With the above structure, the feed channel can be used to transport the pellets, which has the advantage of simple structure.

[0044] In this embodiment, the guide shaft 322 is located below the second baffle plate 18. The second baffle plate 18 is a bent plate with a certain bend.

[0045] like Figure 1 As shown, a filter screen 141 is provided at the opening of the whole pill cavity 14. The filter screen 141 can block large pieces of slag and allow the whole pill to pass through, so as to facilitate the cleaning of the large pieces of slag.

[0046] In this embodiment, the residue chamber includes a residual pill chamber 15 and a crushed slag chamber 16 arranged in the transverse direction, and the residual pill chamber 15 is located between the whole pill chamber 14 and the crushed slag chamber 16. With the above structure, the residual pills and the crushed slag with a smaller particle size can be separated, and the residual pills enter the residual pill chamber 15, and the crushed slag enters the crushed slag chamber 16.

[0047] Specifically, the wind entering through the air inlet 12 can blow the residual pellets and the debris to separate them.

[0048] The housing 10 is further provided with a first partition plate, a second partition plate and a third partition plate. The first partition plate is arranged above the cavity openings of the whole pill cavity 14 and the residual pill cavity 15, and can prevent the whole pills from entering the residual pill cavity 15. The second partition plate is arranged above the residual pill cavity 15 and the slag cavity 16, and can prevent the residual pills from entering the slag cavity 16. The third partition plate can guide the slag into the slag cavity 16 and discharge the dust from the air outlet 13.
