Technical Field

[0001] The utility model belongs to the technical field of basalt aggregate particle shape adjustment, in particular to an adjustment device for basalt aggregate particle shape control. Background Art

[0002] Basalt aggregate refers to aggregate made from basalt stone, which is usually used in the production of concrete, asphalt and other materials in the construction field. It is a volcanic rock with a certain stability and durability in its chemical composition. Therefore, it is widely used in the construction field. In order to improve the uniformity of basalt aggregate, it is usually necessary to adjust and classify the basalt aggregate according to the particle shape. The existing basalt aggregate particle shape control is mostly adjusted through a sand and gravel sorting device, which has a single sorting structure and few grades. The equipment has large resistance during operation, low efficiency and poor precision. Therefore, this paper proposes an adjustment device for basalt aggregate particle shape control to solve the above problems. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides an adjustment device for basalt aggregate particle shape control, which effectively solves the problem of low efficiency and poor classification accuracy of the current basalt aggregate particle shape control using water-washed sand and gravel separation.

[0004] The technical solution adopted by the utility model is as follows: the utility model proposes an adjustment device for controlling the particle shape of basalt aggregate, comprising a V-selection air inlet, a feed inlet and a fan, the feed inlet being arranged at the upper end of the V-selection air inlet, the fan being arranged on the side wall of the V-selection air inlet and connected with the V-selection air inlet, a scattering plate and a grading plate being provided on the inner wall of the V-selection air inlet, the scattering plate being arranged below the feed inlet, the grading plate being arranged on the side of the scattering plate away from the fan, a medium sand aggregate cone being provided on the side of the V-selection air inlet close to the grading plate, an arc-shaped guide plate being provided at the upper end of the medium sand aggregate cone, a cage-shaped conveyor being rotatably connected to the arc-shaped guide plate, a fine sand collecting cone being provided at the lower end of the arc-shaped guide plate, a cyclone dust collector being provided on the side wall of the arc-shaped guide plate, the upper end of the arc-shaped guide plate being rotatably connected to a transmission shaft, and the lower end of the transmission shaft being connected to the cage-shaped conveyor, and a pulley being provided at the upper end of the transmission shaft.

[0005] Furthermore, a coarse sand outlet is provided at the bottom of the V-selected air inlet, a medium sand outlet is provided at the lower end of the medium sand aggregation cone, a fine sand outlet is provided at the lower end of the fine sand collection cone, the upper end of the cyclone dust collector is connected to the cyclone dust collector outlet pipe, and a fine powder outlet is provided at the bottom of the cyclone dust collector.

[0006] Furthermore, the cage-shaped conveyor and the transmission shaft are coaxially arranged, and a bearing is provided between the upper end of the arc-shaped guide plate and the transmission shaft.

[0007] Furthermore, the V-select air inlet is arranged in a V shape.

[0008] The beneficial effects achieved by the utility model using the above structure are as follows:

[0009] 1. Advanced sorting principle: It has multiple grading systems and uses aviation aerodynamic analysis to optimize the material flow field based on the characteristics of basalt sand and gravel. This significantly reduces equipment operating resistance, improves sorting efficiency, and significantly reduces energy consumption, making it superior to traditional water-washed sand and gravel sorting production processes.

[0010] 2. The V-shaped breaking and grading area has a simple structure, less consumables, no electric breaking device, small pressure difference loss, stable operation and low power consumption;

[0011] 3. High sorting accuracy: The de-powdering machine adopts "eddy current rectifier". The airflow in the rectifier only rises but does not rotate relative to the rotor. The material is repeatedly cleaned in the sorting area, and the classification accuracy is high;

[0012] 4. Simple operation: The cage rotor adopts variable frequency stepless speed regulation, with a wide adjustment range, convenient adjustment, sensitive and reliable;

[0013] 5. High classification efficiency: The "V"-shaped powder separation area is equipped with multiple layers of breaking and classifying plates, which repeatedly break up and blow away the fine powder, so that there is almost no fine powder in the discharged coarse powder; the airflow at the powder discharge port of the sedimentation classification area blows away the fine powder in the intermediate material again, and the fine powder content in the intermediate material is also greatly reduced. The cage rotor classification area is equipped with a guide plate, making the classification more accurate and effective;

[0014] 6. Wear-resistant parts require less maintenance and have a long service life: Imported wear-resistant steel plates are used on vulnerable parts of major components, effectively extending their service life; the entire machine has been dynamically balanced and operates smoothly within the full speed range;

[0015] 7. The new design of the main shaft lower bearing seal effectively solves the two major problems of dust ingress and lubricating oil leakage, effectively extending the bearing service life;

[0016] 8. When designing the de-powdering machine foundation, the principle of mechanical vibration reduction is adopted to ensure that the vibration frequency of the separator foundation does not form an integer multiple relationship with the separator's natural frequency, fundamentally solving the long-standing separator resonance problem;

[0017] 9. The coarse sand pipe, medium and fine sand pipe and fine sand pipe all use double interlocking air valves, which greatly reduces the system air leakage rate and overcomes the defect of large dust during the operation of the previous de-dusting machine;

[0018] 10. The system uses double interlock air valves and internal circulation air to effectively reduce system air leakage and reduce dust emission pollution during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the present invention proposes an adjustment device for controlling the particle shape of basalt aggregate, comprising a V-selected air inlet 3, a feed port 1 and a fan 2, wherein the feed port 1 is arranged at the upper end of the V-selected air inlet 3, the fan 2 is arranged on the side wall of the V-selected air inlet 3 and is connected to the inside of the V-selected air inlet 3, a scattering plate 4 and a grading plate 5 are arranged on the inner wall of the V-selected air inlet 3, the scattering plate 4 is arranged below the feed port 1, and the grading plate 5 is arranged on the side of the scattering plate 4 away from the fan 2, and the V-selected air inlet 3 is provided with a scattering plate 4. A medium sand aggregate cone 7 is provided on one side near the grading plate 5. An arc-shaped guide plate 9 is provided on the upper end of the medium sand aggregate cone 7. A cage-shaped conveyor 10 is rotatably connected in the arc-shaped guide plate 9. A fine sand collecting cone 11 is provided at the lower end of the arc-shaped guide plate 9. A cyclone dust collector 13 is provided on the side wall of the arc-shaped guide plate 9. A transmission shaft 14 is rotatably connected to the upper end of the arc-shaped guide plate 9, and the lower end of the transmission shaft 14 is connected to the cage-shaped conveyor 10. A pulley 16 is provided at the upper end of the transmission shaft 14.

[0024] In order to realize the discharge of aggregates of different sizes, a coarse sand outlet 6 is provided at the bottom of the V-selected air inlet 3, a medium sand outlet 8 is provided at the lower end of the medium sand aggregate cone 7, a fine sand outlet 12 is provided at the lower end of the fine sand collection cone 11, the upper end of the cyclone dust collector 13 is connected to the cyclone dust collector 13 outlet pipe, and the bottom of the cyclone dust collector 13 is provided with a fine powder outlet 18.

[0025] The cage-shaped conveyor 10 and the transmission shaft 14 are coaxially arranged, and a bearing 15 is provided between the upper end of the arc-shaped guide plate 9 and the transmission shaft 14; the V-selective air inlet 3 is arranged in a V shape.

[0026] During use, external conveying equipment is used to feed the basalt aggregate raw materials from the feed port 1 and into the scattering area in the V-selected air inlet 3. Under the action of several groups of scattering plates 4, sand of different particle sizes produces different falling speeds during the falling process, causing several relative frictions between the sand particles. In this way, the mud powder and stone powder on the surface of the sand particles are peeled off and quickly leave the surface of the sand under the action of wind, so that the sand can be fully cleaned.

[0027] Specifically, the material coming in through the feed port 1 is broken up and peeled off by the multi-stage breaking plates 4. The wind from the fan 2 is used between the breaking plates 4 to blow away the coarse and fine materials in the material flow, and the coarse sand is discharged from the coarse sand outlet 6 at the bottom of the V-selection air inlet 3. The material suspended in the air flow is carried by the wind into the multi-layer grading plates 5 in the grading area. The grading plates 5 further remove the relatively coarse materials from the material suspended in the air flow, and the coarse materials slide down along the grading plates 5. The remaining materials are blown up again by the wind and repeatedly sorted. Finally, the coarse powder is merged into the coarse sand. The wind-carrying material out of the grading plates 5 enters the medium material grading area. In the medium material grading area, due to the deceleration of the air flow and the deflection of the direction, the medium sand is generated by gravity sedimentation and impact on the wall. The medium sand is settled from The medium sand is discharged from the outlet 8, and the remaining air flow carries the material into the fine material classification area. In the fine material classification area, the material rotates under the action of the arc-shaped guide plate 9, forming a dual effect of centrifugal sedimentation and gravity sedimentation. The fine sand falls into the fine sand collecting cone 11 below and is discharged from the fine sand outlet 12. The powder enters the de-powdering area with the air flow, and the slightly coarse material (fine sand) is thrown out under the action of the cage-shaped conveyor 10. The fine sand hits the arc-shaped guide plate 9 and falls into the fine sand collecting cone 11. The powder-containing air flow enters the cyclone dust collector 13 for gas-solid separation. The separated fine powder is discharged from the fine powder outlet 18, and the relatively clean air enters the fan 2 through the air outlet pipe for recycling. The above is the entire use process of the adjustment device for basalt aggregate particle shape control.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
