For example, step two and step three can be swapped or run in parallel.
[0023] As Figure 1 shown, according to an exemplary embodiment of the present utility model, a sandblasting machine anti-clogging sieve is provided, including: a sloped filter screen surface 11, an outer slope 12, an inner slope 13, a positioning cylinder 14, a stand 20, and a sand feeding channel 30.
[0024] More specifically, the sandblasting machine anti-clogging sieve is mainly composed of a sieve main body 10 and a stand 20. The sieve main body 10 is in the shape of a hollow cone when viewed frontally, including: a sloped filter screen surface 11 on one side of the top that constitutes the outer cone surface of the cone and an outer slope 12 on one side of the bottom, a positioning cylinder 14 whose shape fits into the sand feeding channel 30, and an inner slope 13 connecting the outer slope 12 and the upper end side of the positioning cylinder 14; the stand 20 is provided with a sand feeding channel 30 that penetrates through, and the sand feeding channel 30 may be formed with a tube body extending downward from the central hole of the stand 20 to be connected to the sand pipe of the sandblasting machine.
[0025] During use, the sieve main body 10 is buckled directly above the sand feeding channel 30, with its surroundings resting on the stand 20, and the internal positioning cylinder 14 is inserted into the sand feeding channel 30. The vertex of the sieve main body 10 and the center point of the sand feeding channel 30 are on the same axis. At this time, the sand feeding channel 30 is communicated with the sand pipe of the sandblasting machine.
[0026] That is, after inserting from the upper end opening side of the lower sand passage 30 to the lower end side of the positioning cylinder 14, the lower end side of the outer slope 12 abuts against the surface of the gantry 20, and the lower sand passage 30 communicates with the sand pipe of the sandblasting machine. Since the inner slope 13 is in the shape of a flared conical surface as it goes from the upper end side of the positioning cylinder 14 to the upper side of the outer slope 12, a space is formed between the slope filter screen surface 11 and the inner slope 13 for the sand filtered by the slope filter screen surface 11 to fall towards the positioning cylinder 14.
[0027] In some embodiments, the following can be preferably set.
[0028] The slope filter screen surface 11 has evenly distributed screen holes with a density of 50 meshes, and the sand used is between 50 - 70 meshes.
[0029] The included angle between the outer slope 12 and the inner part of the gantry 20 is 33°, and the outer angle is 147° (see Figure 4 ).
[0030] The included angle between the inner slope 13 and the outer slope 12 is 50°. The inner slope 13, the outer slope 12, and the positioning cylinder 14 are connected by welding, and the slope filter screen surface 11 and the outer slope 12 are connected by welding. In this way, all the filtered sand can fall into the lower sand passage 30 without staying on the upper gantry (not shown) of the sandblasting machine.
[0031] The positioning cylinder 14 is tightly connected to the inner wall of the lower sand passage 30, and the gap is allowed to be between 0.5 - 1 mm, which plays a role in positioning and preventing movement. For greater stability, the wall length L of the positioning cylinder 14 reaches more than 500 mm to ensure the overall stability.
[0032] The entire strainer body 10 is cast from wear-resistant high-carbon steel (specifically, T10 composition) (for example, the above-mentioned components can be cast separately and then welded together). After heating to 800 °C and holding for 20 min, it is quenched in salt water, and then a tempering process (230 °C * 3 h) is carried out, and it is slowly cooled to room temperature.
[0033] The connection point between the inner slope 13 and the upper end side of the positioning cylinder 14 and the bottom end of the outer slope 12 are located on the same horizontal plane perpendicular to the axis of the hollow cone. At this time, after inserting the lower end side of the positioning cylinder 14 from the upper end opening side of the lower sand passage 30, the lower end side of the outer slope 12 just abuts against the surface of the gantry 20.
[0034] <Variant 1>
[0035] At the upper end opening side of the lower sand passage 30, a stepped enlarged hole 21 is formed. As Figure 2 shown, it can align the inner wall of the positioning cylinder 14 with the lower inner wall of the lower sand passage 30, and at the same time, the positioning cylinder 14 can be formed with a larger inner diameter to facilitate rapid sand discharge.
[0036] <Modification Example 2>
[0037] The upper end side of the lower sand passage 30 is formed in a chamfered manner, facilitating the insertion of the lower end side of the positioning cylinder 14 from the upper end opening side of the lower sand passage 30. At the same time, the shape of the lower end side of the inner slope 13 can be adapted to the chamfered part (not shown).
[0038] Correspondingly, an annular hollow groove 22 is formed on the surface of the mounting table 20 (refer to Figure 3 ), and the hollow groove 22 has a shape matching the lower end side of the outer slope 12 (especially a groove wall surface with an inclined direction opposite to the chamfered part), so that the lower end side of the outer slope 12 can be abutted against the surface of the mounting table 20 by inserting it into the hollow groove 22. At the same time, the chamfered part with the opposite inclined direction can be used to enhance the stability of the sieve net body 10.
[0039] <Modification Example 3>
[0040] A convex strip extending in the axial direction is formed on the outer peripheral wall of the positioning cylinder 14 (not shown) to cooperate with a groove (not shown) formed on the inner peripheral wall of the lower sand passage 30 for positioning.
[0041] <Modification Example 4>
[0042] Instead of the inner slope 13 and the positioning cylinder 14, a double-sided slope platform 16 is formed above the mounting table 20 around the lower sand passage 30. On the upper surface of the mounting table 20 on the outer peripheral side of the double-sided slope platform 16, the above-mentioned hollow groove 22 is formed.
[0043] The inner slope surface of the double-sided slope platform 16 is formed into a tapered surface corresponding to the flared opening of the above-mentioned inner slope 13, and the outer slope surface of the double-sided slope platform 16 is formed into a shape that can be shape-fitted to the inner peripheral wall of the outer slope 12.
[0044] The double-sided slope platform 16 is preferably integrally formed on the mounting table 20, or separately provided on the mounting table 20 and the outer slope 12 (it can be configured into a split-type shape locking relationship, not further shown here). Thus, the hollow conical sieve net body 10 can be directly placed on the mounting table 20, and at the same time, it is shape-fitted with the outer slope surface of the double-sided slope platform 16 and the hollow groove 22.
[0045] For the sandblasting machine anti-clogging sieve net provided as above, aluminum chips can be effectively screened out. As long as the aluminum chips are regularly cleaned, the smoothness of the sand pipe can be effectively guaranteed, the sandblasting stability is ensured, the color difference consistency of the profiles is guaranteed, and the unsmooth operation of the equipment leading to production stoppage is avoided.
