Description

Technical Field

[0001] The utility model relates to the technical field of sand and powder separation equipment, in particular to sand and powder separation equipment for machine-made sand. Background Art

[0002] With the acceleration of urbanization, the demand for concrete in society has increased rapidly. In the production of concrete, artificial sand is needed as raw material. Artificial sand refers to sand processed by sand making machines and other auxiliary equipment. In the process of stone processing, due to fierce collisions and the fact that the stone itself has a certain amount of soil, the produced artificial sand contains a certain amount of stone powder and mud powder. In order not to affect the quality of the sand, a separation device is needed to remove the dust in the sand.

[0003] Based on the above, when the existing separation device separates the machine-made sand into sand powder, the machine-made sand is usually directly poured into the feed end of the separation device for feeding and separation. Since the feeding amount and feeding speed of the machine-made sand cannot be controlled, the sand powder of the machine-made sand accumulates during separation, resulting in a long time for flattening the sand powder when screening and separating the sand powder, which affects the separation efficiency of the sand powder and causes uneven separation of the sand powder.

DETAILED DESCRIPTION

[0027] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] See also Figure 1-Figure 4 A sand powder separation device for machine-made sand, whose structure includes a main body 1, a feeding mechanism 2, a separation mechanism 3 and a collecting box 4. The main body 1 is equipped with a feeding mechanism 2 capable of feeding machine-made sand, one side of the feeding mechanism 2 is rotatably matched with the separation mechanism 3, and a collecting box 4 is provided on one side of the main body 1 close to the discharge end of the separation mechanism 3.

[0030] In this embodiment, a hinge sleeve 5 is installed on one side of the separation mechanism 3 , and the other side of the hinge sleeve 5 is rotatably matched with the main body 1 , so that the separation mechanism 3 can rotate up and down on the main body 1 .

[0031] In this embodiment, the blanking mechanism 2 includes a feed hopper 21, a base plate 22, a discharge slope 23, a dual-axis motor 24, a ball screw 25, a movable seat 26 and a blanking baffle 27. The bottom discharge port of the feed hopper 21 is connected to the base plate 22. The base plate 22 is located on the main body 1. A discharge slope 23 for discharging machined sand is provided directly below the base plate 22. A dual-axis motor 24 is installed on the base plate 22. Ball screws 25 are connected to the output ends on both sides of the dual-axis motor 24. Both ball screws 25 are slidably fitted with a movable seat 26 through a guide member. Blanking baffles 27 are installed on the side of the two movable seats 26 close to the feed hopper 21. The blanking baffle 27 can pass through the feed hopper 21 and slidably fit with the feed hopper 21.

[0032] In this embodiment, when the dual-axis motor 24 drives the two sets of moving seats 26 and the blanking baffle 27 to move toward each other through the rotation of the ball screw 25, the size of the discharge port of the feed hopper 21 can be controlled by means of the moving distance of the blanking baffle 27 in the feed hopper 21, thereby controlling the discharge speed of the machine-made sand, and avoiding accumulation of the machine-made sand due to excessive discharge speed.

[0033] Working principle: the machine-made sand is poured into the feed hopper 21 on the blanking mechanism 2, and the machine-made sand is discharged through the discharge port at the bottom of the feed hopper 21 and falls on the discharge slope 23. The inclination of the discharge slope 23 can make the machine-made sand slide onto the separation mechanism 3 for sand powder separation. When it is necessary to control the discharge speed of the machine-made sand, the ball screws 25 at both ends are driven to rotate by the double-axis motor 24. With the rotation of the ball screw 25, the two sets of moving seats 26 can move towards each other on the ball screw 25 with the help of the guide member, thereby driving the blanking baffle 27 fixed to the moving seat 26 to move in the feed hopper 21 together, thereby controlling the size of the discharge port of the feed hopper 21, and being able to control the discharge speed of the machine-made sand to avoid accumulation due to excessive discharge speed of the machine-made sand.

[0034] Embodiment 2:

[0035] See also Figure 5-Figure 6 The utility model is a sand powder separation device for machine-made sand. Compared with the first embodiment, the present embodiment also includes: a separation mechanism 3 includes an inclined bucket 31, a U-shaped seat 32, a motor 33, and an eccentric block 34. A U-shaped seat 32 connected to the main body 1 is provided directly below the inclined bucket 31. A motor 33 is installed on one side of the U-shaped seat 32. The motor 33 is connected to the eccentric block 34 through the output end and can drive the eccentric block 34 to rotate. The eccentric block 34 is in contact with the inclined bucket 31.

[0036] In this embodiment, one side of the inclined bucket 31 is connected to the hinge sleeve 5 and rotates with the main body 1 through the hinge sleeve 5. When the motor 33 drives the eccentric block 34 to rotate, through the active contact between the eccentric block 34 and the inclined bucket 31, the inclined bucket 31 can be driven to make an up and down shaking motion under the support of the hinge sleeve 5 during rotation.

[0037] In this embodiment, a guide plate 41 capable of guiding the flow of machine-made sand is installed on the inclined bucket 31, and slots 42 are symmetrically provided on the baffle plates on both sides of the inclined bucket 31, and a separation mesh plate 43 is slidably fitted on the slots 42, and trapezoidal blocks 44 are installed on both sides of the separation mesh plate 43, and the trapezoidal blocks 44 can slide and engage with the slots 42.

[0038] In this embodiment, two groups of the card slots 42 and the separation mesh plates 43 are provided, so as to form two spaced-apart separation barriers to separate the machine-made sand from the sand powder.

[0039] Working principle: When the machine-made sand falls onto the discharge slope 23 through the material dropping mechanism 2, and slides onto the inclined bucket 31 through the discharge slope 23, the motor 33 located on the U-shaped seat 32 is driven to operate, and the motor 33 drives the eccentric block 34 connected thereto to rotate eccentrically. With the active contact between the eccentric block 34 and the inclined bucket 31, the eccentric block 34 can drive the inclined bucket 31 to shake up and down under the support of the hinge sleeve 5 when rotating, thereby driving the machine-made sand on the inclined bucket 31 to shake together, thereby increasing the separation effect and separation speed of the machine-made sand on the separation mesh plate 43 of the inclined bucket 31. The separation mesh plate 43 can block the sand of the machine-made sand, and collect the stone powder dust with the help of the collection box 4 on one side;

[0040] After the sand and powder separation operation of the machine-made sand is completed, the separation mesh plate 43 can be pulled away from the inclined bucket 31 through the sliding cooperation between the clamping groove 42 and the trapezoidal clamping block 44, so as to facilitate the collection of the sand and gravel remaining on the inclined bucket 31.
