Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 to 6, the method for classifying silica sand for casting mainly uses different initial velocities of sand grains of different masses driven by the same kinetic energy, and finally performs size classification on the sand grains due to different displacements of the sand grains moving in the horizontal direction. Based on this principle, this embodiment provides a raise sand and classify equipment, including air supply mechanism 2, mix sand storage mechanism 1 and finished product storage mechanism 3, above-mentioned mechanism can install on position control mechanism (position control mechanism adopts prior art, for example linear guide, and its specific structure does not do the perplexing in this application), can adjust air supply mechanism 2 and mix sand storage mechanism 1's position according to actual need, and wherein, mix sand storage mechanism 1 and construct and adjust along vertical direction, and air supply mechanism 2 is adjusted along the horizontal direction.
The bottom of the mixed sand storage mechanism 1 is provided with a sand outlet 11, the air supply mechanism 2 and the finished product storage mechanism 3 are respectively positioned at two sides of the sand outlet of the mixed sand storage mechanism 1, the air supply mechanism 2 is used for providing power for movement of sand grains 4, and the finished product storage mechanism 3 is arranged below the mixed sand storage mechanism 1 and used for receiving the screened sand grains 4.
The mixed sand storage mechanism 1 comprises a mixed sand hopper, and a sand outlet 11 at the bottom of the mixed sand hopper is of a straight-line structure and used for controlling sand grains 4 to uniformly and transversely distribute and flow out of the sand outlet 11. An adjusting mechanism is arranged in the sand outlet 11 and comprises a spring piece 51 and an adjusting screw 52. Mix sand hopper's 11 inner walls of sand outlet symmetry and be equipped with two spring leaf 51, spring leaf 51's one end and 11 inner wall fixed connection of sand outlet, the other end extends to 11 edges of sand outlet, 11 lateral wall symmetries of sand outlet are equipped with two adjusting screw 52, and adjusting screw 52 locates and is close to sand outlet edge one side, and adjusting screw 52's one end runs through the sand outlet lateral wall to contact with spring leaf 51. The distance between the two spring pieces 51 is adjusted by clamping or unclamping the spring pieces 51 by rotating the adjusting screw 52, thereby adjusting the size of the linear gap of the sand outlet 11 and further controlling the sand passing amount.
An adjusting mechanism is also arranged in the air outlet 21 of the fan, so that the size of the cross section area of the air outlet 21 can be adjusted, and the air quantity is further adjusted to adapt to sand grains with different qualities. Similarly, two spring strips 51 are symmetrically fixed on the inner wall of the air outlet 21 of the blower, the other ends of the spring strips 51 extend to the edge of the air outlet 21, and two symmetrically arranged adjusting screws 52 penetrate through the side wall of the air outlet 21 and are in contact with the spring strips 51. The spring plate 51 is clamped or loosened by rotating the adjusting screw 52, so that the distance between the two spring plates is adjusted, and the air throughput of the air outlet 21 is controlled.
Finished product storage mechanism 3 locates and mixes sand storage mechanism 1 below, including the finished product sand hopper, it is a plurality of the finished product sand hopper is the straight line and sets gradually along the air-out direction of fan, and the orientation of putting of finished product sand hopper is mutually perpendicular with a font length direction of sand outlet 11, and the up end of finished product sand hopper is less than the air outlet lower surface of fan, places different finished product sand hoppers 3 according to the horizontal displacement of different grit sand grains 4 and receives sand grains 4.
Before the sand is blown out and the grains are separated, the fittings are installed according to the operation rules, whether all the parts of the equipment are installed in place or not is checked, whether all the parts can work normally or not is checked through an empty test, and whether the silica sand to be separated is distributed into the mixed sand hopper or not is confirmed. After the equipment is checked normally, the rotating speed of the fan 2, the horizontal distance B and the vertical distance A between the air outlet 21 and the sand outlet 11 are adjusted according to the integral particle size distribution of the silica sand or the reclaimed sand, and the horizontal distance C and the vertical distance D between the sand outlet 11 of the mixed sand hopper and the finished sand hopper 3 are adjusted. And after the parameter setting is finished, the classification operation is started.
In the classification process, the fan parameters can be adjusted according to the particle size distribution of sand grains in the finished product sand hopper 3 to ensure that different sand grains have the same kinetic energy, so that the sand outlet speeds of different sand grains are different. When the whole grain size of the sand is thicker, the flowability of the coarse sand is better, the cross section area of the air outlet 21 is adjusted through the adjusting mechanism to be properly reduced so as to improve the air outlet speed, and meanwhile, the distance between the sand outlet nozzles, namely the horizontal distance B between the air outlet 21 and the sand outlet 11 is adjusted so as to be properly reduced so as to prolong the horizontal displacement of the sand. Because the power of fan is fixed, when the air outlet cross-sectional area diminishes, air-out speed can the grow, reduces the interval of play sand mouth simultaneously for the fan can supply the initial velocity of sufficient horizontal direction for the sand grain of coarse grain, if horizontal direction speed is not enough, the phenomenon that the sand grain can not fly to go in the finished product sand hopper can appear. On the contrary, when the overall grain size of the sand is small, the cross-sectional area of the air outlet 21 is adjusted to be large, and the interval between the sand outlets is adjusted to be large. The size of the sand grains after the classification is distributed from coarse to fine to near to far, the particle size concentration is higher, and the method is more favorable for the later-stage adjustment and casting of the needed particle size distribution.
After the separation is finished, the silica sand or the reclaimed sand with different granularities is discharged and bagged according to the requirements of different granularities. The surrounding environment of the testing equipment is cleaned, and the surfaces of all the parts are ensured to be clean and free of floating sand. Use the utility model discloses a raise sand and divide grain device carries out the classification to the silica sand grain, and the classification result is as shown in fig. 6, and the sand grain quality of the different granularities in the digital representation each finished product sand fill accounts for the proportion of total mass in the finished product sand fill in, can find out and adopt this raise sand and divide grain equipment to the screening of sand grain, and the granularity distinguishes accuracy, careful, efficient. The actual result of the particle size distribution can completely meet the actual sand using requirement and the sand blending requirement of a foundry.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
