High-efficiency shaping machine

Abstract

This utility model discloses a high-efficiency shaping machine, including a casing and a cyclone dust collector. Beneficial effects: This utility model employs a cyclone dust collector and an airlock unloader. During sand and gravel shaping, a drive motor rotates the shaping head to shape the sand and gravel. During the shaping process, an exhaust fan starts, drawing out the air inside the cyclone dust collector. External air enters the casing along the hopper and then into the cyclone dust collector via the air delivery pipe. The resulting airflow carries dust into the cyclone dust collector for dust removal. Because the top of the hopper is under negative pressure, dust cannot escape, thus preventing dust leakage and facilitating clean production. Simultaneously, the airlock unloader can lock the air during continuous discharge, further preventing dust leakage without affecting normal discharge, improving work efficiency and ease of use. The entire process does not require water, eliminating the hassle of subsequent heating and drying, saving water and energy, and increasing work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of sand and gravel shaping machine technology, specifically to a high-efficiency shaping machine. Background Technology

[0002] Shaping machines, also known as sizing machines, are mostly used in the field of sand and gravel shaping. Shaping machines are widely used in various industries in our lives. In the shaping of sand and gravel, the commonly used shaping machines currently are mostly used to throw materials at high speed in a high-speed rotating impeller, and achieve fine crushing and shaping through the collision between materials. After screening, the desired material is obtained.

[0003] After searching, it was found that application number CN202123025976.9, entitled "Sand and Gravel Shaping Machine," addresses the problem that existing sand and gravel shaping machines easily generate a large amount of dust during the shaping process, which can be inhaled by workers and cause harm. The dust is removed by spraying, and then dried by a fan. However, because the sand and gravel are very moist after spraying, traditional fan drying is insufficient for rapid drying, leading to increased drying time and reduced work efficiency. Furthermore, spraying for dust removal is wasteful of water resources. Additionally, the shaping head in this application is suspended, and its bottom rotation is unstable, resulting in overall instability during operation. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the aforementioned advantages of water and energy saving, high work efficiency, and stable operation, the specific technical solution adopted by this utility model is as follows:

[0009] A high-efficiency shaping machine includes a casing and a cyclone dust collector. A top cylinder is fixedly installed on the top surface of the casing, and a lifting plate is slidably connected inside the top cylinder. A drive motor is fixedly installed on the top surface of the lifting plate. A shaping head is installed at the output end of the drive motor, and a splined cylinder is fixedly installed on the bottom surface of the shaping head. A hydraulic cylinder is fixedly installed on the top surface of the top cylinder, and a lifting frame is fixedly connected to the other end of the piston rod of the hydraulic cylinder. The bottom surface of the lifting frame is fixedly connected to the top surface of the lifting plate. The air inlet of the cyclone dust collector is connected to the casing through an air supply pipe, and the exhaust end of the cyclone dust collector is connected to an exhaust fan through an exhaust pipe. An airlock unloader is connected to the bottom surface of the casing through a discharge channel.

[0010] Furthermore, a hopper is connected through the top surface of the casing.

[0011] Furthermore, a spline shaft is rotatably connected to the bottom surface of the housing via a rotary connecting seat, and the spline shaft is connected to a spline key.

[0012] Furthermore, heat dissipation holes are provided on the top surface of the top cylinder.

[0013] Furthermore, a sealing ring is fixedly bonded to the outer wall of the lifting plate, and the outer wall of the sealing ring slides against the inner wall of the top cylinder.

[0014] Furthermore, the drive motor, shaping head, splined cylinder, splined shaft, and rotary connecting seat are arranged in the same group.

[0015] Furthermore, the bottom surface of the housing has a bottom opening located outside the rotating connecting seat.

[0016] Furthermore, support legs are fixedly installed on the surface of the housing.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a high-efficiency shaping machine with the following advantages:

[0019] (1) This utility model adopts a cyclone dust collector and an airlock unloader. When shaping sand and gravel, the crushed sand and gravel can be fed from the hopper into the machine casing. The drive motor drives the shaping head to rotate and shape the sand and gravel. During the shaping process, the exhaust fan is started to extract the air inside the cyclone dust collector. The outside gas enters the machine casing along the hopper and enters the cyclone dust collector along the air conveying pipe. The formed flowing air carries the dust into the cyclone dust collector for dust removal. Since the top of the hopper is under negative pressure, the dust cannot escape, thus avoiding dust leakage and facilitating clean production. At the same time, the airlock unloader can lock the air during continuous discharge, further preventing dust leakage and not affecting normal discharge. This improves work efficiency and ease of use. The whole process does not require water, saving the trouble of later heating and drying. It saves water and energy and has higher work efficiency.

[0020] (2) This utility model adopts a lifting plate, a splined cylinder and a splined shaft. The extension and retraction of the hydraulic cylinder can drive the lifting plate to move up and down, thereby driving the shaping head to move up and down, changing the shaping particle size, which is convenient for adjustment. During the up and down movement of the shaping head, the splined cylinder and the splined shaft always maintain a key connection state, stabilizing the rotation state of the bottom of the shaping head, thereby stabilizing the operation of the shaping head, improving the stability of the operation, and further improving the work efficiency.

[0029] According to an embodiment of the present invention, a high-efficiency shaping machine is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to them. Figure 1 and Figure 2The high-efficiency shaping machine according to an embodiment of this utility model includes a housing 1 and a cyclone dust collector 13. The housing 1 is welded from Q345B low-alloy high-strength steel with a wall thickness of 10mm. It is annealed to eliminate welding stress. A top cylinder 2 is fixedly installed on the top surface. The top cylinder 2 is welded to the top surface of the housing 1 by argon arc welding, with a weld height ≥8mm. The top cylinder 2 and the housing 1 are coaxially arranged, with a coaxiality error ≤0.1mm. A drive motor 6, model Y2-200L2-2, with a power of 37kW and a speed of 2950r / min, is fixedly installed on the top surface of the lifting plate 5. The output shaft of the drive motor 6 passes through the lifting plate 5 and is connected to the lifting plate 5 through a 6315 deep groove ball bearing with a rated dynamic load of 108kN. A shaping head 8 is mounted on the output end of the drive motor 6. The shaping head 8 is made of high-chromium cast iron with a surface hardness of HRC58-62. Specifically, the other end of the output shaft of the drive motor 6 is connected to the mounting end of the shaping head 8 by high-strength bolts, M20 bolts with a tightening torque of 350 N·m. A high-manganese steel wear-resistant strip, 20 mm thick and with a hardness of HB300-350, is vertically fixed to the inner wall of the housing 1; this is a common structure in this field. A splined cylinder 16 is fixedly mounted on the bottom surface of the shaping head 8. The spline specifications are 8×42×48×8, conforming to GB / T1144-2001 standard. A hydraulic cylinder 3, model HSG-100 / 63-300, with a stroke of 300mm, rated pressure of 16MPa, and maximum thrust of 78.5kN, is fixedly installed on the top surface of the top cylinder 2. The piston rod of the hydraulic cylinder 3 is fixedly connected to a lifting frame 4, which is welded from rectangular steel pipes with a cross-sectional dimension of 100mm×50mm×5mm. The bottom surface of the lifting frame 4 is fixedly connected to the top surface of the lifting plate 5 with M16 bolts. The drive motor 6 is installed inside the lifting frame 4, with a 50mm heat dissipation gap between the lifting frame 4 and the drive motor 6. The cyclone dust collector 13, model XLP-B, has a processing air volume of 15000m³. 3 The air inlet is connected to the casing 1 via an air supply pipe 12, which has a diameter of 200mm. The exhaust end of the cyclone dust collector 13 is connected to an exhaust fan 14 via an extraction pipe 15. The fan is model 4-72No.6C, has a power of 15kW, and a flow rate of 12000m³ / h. 3 / h. The bottom surface of the casing 1 is connected to a lock-air unloader 11 through the discharge channel 10. The model is YJD-HX-16, with a processing capacity of 20t / h and a motor power of 1.5kW. During sand and gravel shaping, the crushed sand and gravel can be fed into the casing 1 from the hopper 7. The drive motor 6 drives the shaping head 8 to rotate at 2950r / min to perform high-speed impact shaping of the sand and gravel. During the shaping process, the exhaust fan 14 is started, forming a negative pressure of -500Pa inside the casing 1. External gas is supplemented into the casing 1 along the hopper 7, carrying dust along the air conveying pipe 12 into the cyclone dust collector 13 for dust removal. The dust removal efficiency is ≥99%. Because the top opening of the hopper 7 is in a negative pressure state, the dust cannot escape, thus avoiding dust leakage. Meanwhile, the airlock unloader 11 can perform airlock unloading during continuous discharge, with a discharge gap of ≤0.5mm, further preventing dust leakage without affecting normal discharge, and achieving a discharge capacity of 15-20t / h. The entire process does not require water, saving 100% of water compared to wet shaping, eliminating the hassle of subsequent heating and drying, and reducing energy consumption by 30%.

[0031] Please refer to Figure 1 and Figure 3 The top surface of the casing 1 is connected to a hopper 7. The hopper 7 adopts a conical structure with an upper diameter of 800mm and a lower diameter of 300mm. It is located on the other side of the top cylinder 2 with an inclination angle of 60° to facilitate material feeding by the staff. A guide plate is set inside the hopper 7 to guide the material to be evenly distributed.

[0032] Please refer to Figure 1 and Figure 4 A splined shaft 17 is rotatably connected to the bottom surface of the housing 1 via a rotating connecting seat 18. The rotating connecting seat 18 uses a thrust ball bearing 51216 with a rated dynamic load of 181kN. The splined shaft 17 is keyed to the splined cylinder 16. The splined shaft 17 is made of 40Cr material with a surface hardening hardness of HRC48-52. Specifically, the splined shaft 17 is inserted into the splined cylinder 16 and keyed to it, with a clearance ≤0.08mm. The hydraulic cylinder 3 extends and retracts, driving the lifting plate 5 to move up and down at a speed of 5-20mm / s, which in turn drives the shaping head 8 to move up and down, with an adjustment range of 0-300mm, changing the shaping particle size, with a particle size adjustment range of 5-50mm. During the up and down movement of the shaping head 8, the splined cylinder 16 and the splined shaft 17 always maintain a keyed connection, with a transmission error ≤0.1°, stabilizing the rotation state of the bottom of the shaping head 8, with a speed fluctuation ≤±1%, thereby stabilizing the operation of the shaping head 8 and improving its stability.

[0033] Please refer to Figure 2 and Figure 3 The top surface of the top cylinder 2 has heat dissipation holes, each 10mm in diameter and spaced 50mm apart, arranged in 50 groups, providing a heat dissipation area of ​​0.03m². 2This facilitates heat dissipation for the drive motor 6, with a motor temperature rise of ≤40K.

[0034] Please refer to Figure 1 The outer wall of the lifting plate 5 is fixedly bonded with a fluororubber sealing ring with a Shore hardness of 70A and a cross-sectional size of 20mm×10mm. The outer wall of the sealing ring slides against the inner wall of the top cylinder 2 with a friction coefficient of ≤0.3, sealing gaps and preventing dust from entering the drive motor 6. The protection level reaches IP54, while preventing outside air from entering the housing 1 through the heat dissipation holes and maintaining a stable negative pressure inside the housing.

[0035] Please refer to Figure 1 and Figure 4 The drive motor 6, shaping head 8, splined cylinder 16, splined shaft 17 and rotary connecting seat 18 are arranged in the same group, with coaxiality error ≤0.05mm, improving rotational stability and vibration intensity ≤1.8mm / s, thus improving work efficiency.

[0036] Please refer to Figure 1 The bottom surface of the housing 1 is provided with a bottom opening 9 on the outside of the rotating connecting seat 18. The bottom opening 9 has a diameter of 100mm and is arranged in 8 groups at equal angles. The diameter of the bottom opening 9 is larger than the maximum particle size of the material (50mm). Through finite element analysis, the flow rate is ≥2m / s to avoid clogging.

[0037] Please refer to Figure 1 and Figure 3 Three sets of support legs are fixedly installed on the surface of the casing 1. The support legs are welded from Q235 steel, with a cross-sectional size of 150mm×150mm and a height of 500mm. Shock-absorbing pads with a hardness of Shore 60A are installed at the bottom to provide stable support. The vibration acceleration of the whole machine is ≤5g.

[0038] Working principle:

[0039] Shaping operation: The crushed sand and gravel enter the machine casing 1 from the hopper 7. The drive motor 6 drives the shaping head 8 to rotate at high speed. The impact and grinding action of the high-chromium cast iron shaping head is used to shape the sand and gravel. The linear speed of the shaping head 8 reaches 70-90m / s, causing the sand and gravel particles to undergo plastic deformation and fracture, achieving a shaping effect with uniform particle size.

[0040] Negative pressure dust removal: After the exhaust fan 14 starts, a negative pressure environment of -500Pa is formed inside the casing 1. The dust-laden airflow enters the cyclone dust collector 13 through the air delivery pipe 12. The dust is separated under the action of centrifugal force, and the purified gas is discharged through the exhaust pipe 15. The dust removal efficiency is ≥99%, ensuring that the dust concentration in the working environment is ≤10mg / m³. 3 It meets environmental protection requirements.

[0041] Particle size adjustment: The hydraulic cylinder 3 pushes the lifting frame 4 and the lifting plate 5 up and down, which drives the shaping head 8 to adjust its height (0-300mm), changing the gap between the shaping head and the wear-resistant strip on the inner wall of the machine casing 1, thereby controlling the particle size of the shaped sand and gravel. The larger the gap, the larger the shaped particle size, and vice versa, with an adjustment accuracy of ±1mm.

[0042] Airlock unloading: The shaped material falls into the discharge channel 10 through the bottom opening 9 on the bottom surface of the casing 1. The airlock unloader 11 achieves continuous unloading by rotating the impeller. At the same time, the gap between the impeller and the casing (≤0.5mm) forms an airlock to prevent dust leakage. The unloading capacity reaches 20t / h.

[0043] Structural coordination: The keyed connection structure between the splined cylinder 16 and the splined shaft 17 ensures that the shaping head 8 maintains stable rotation during up and down adjustment. The thrust bearing of the rotating connecting seat 18 supports the axial load of the shaping head, ensuring stability during high-speed rotation. The vibration intensity of the whole machine is ≤1.8mm / s, and the operating noise is ≤85dB.

[0044] This utility model, through innovative designs such as negative pressure dust removal, adjustable shaping gap, and efficient airlock unloading, improves shaping efficiency by 40%, reduces dust emissions by 90%, and lowers energy consumption by 30% compared to traditional shaping machines. It is suitable for efficient shaping operations of building aggregates, mining ores, and other materials.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
