Description

Technical Field

[0001] The invention relates to the technical field of spray drying, and in particular to a fan blade crusher. Background Art

[0002] Spray drying is the main technology for zero wastewater discharge. This technology is accompanied by heat and mass transfer during operation, which will cause changes in the temperature, humidity and particle size of the raw materials. For example, when spray drying high-salt wastewater, liquid droplets will combine with dust in the gas, causing the dust particle size to continue to increase; when the droplets are too large or too much, the dust will condense or agglomerate and become compacted, which not only affects the drying effect but also affects material transportation and subsequent processing; in the process of flue gas waste heat recovery and cooling, "acid dew" will appear due to the influence of water vapor and acidic gas, causing dust to agglomerate and form large-particle sticky materials, which will also cause system operation problems. These cases will affect the normal operation of the equipment.

[0003] In order to solve the technical problem of material compaction in the above-mentioned wastewater spray drying zero-emission process, the common technical means are:

[0004] a) Increase the drying heat. Increasing the drying heat can ensure that the droplets can evaporate quickly and avoid caking; however, the heat consumption will increase, and the operating cost will increase, which does not meet the requirements of the national energy-saving strategy.

[0005] b) Use compressed gas to crush. Compressed air or steam is usually used for spray crushing. This technology has poor crushing performance; the instantaneous gas impact will affect the stability of the original system; this technology is associated with pressure vessels, which are special equipment, have certain safety risks and are relatively expensive; it works non-continuously, and the working frequency needs to be determined according to specific working conditions, making it more difficult to operate and implement.

[0006] c) Use mechanical continuous crushing. Currently known mechanical continuous crushers have the following shortcomings:

[0007] 1) The main shaft is supported by a simple support structure, which makes the equipment large, affects production and is costly. In traditional crusher technology, the main shaft of the crushing device adopts a simple support structure supported at both ends. The main shaft spans both sides of the casing, which is not only large in size but also costly. In order to prevent the bearing from being affected by the internal material, the diameter of the crusher casing is the same as that of the equipment casing, which is not only costly, but also occupies and blocks the material flow channel.

[0008] 2) The overall structure is complex and the efficiency is low. The crushing device and the driving device of the traditional crusher technology are separate structures. The crushing device needs an independent support bearing, and the crushing device and the driving device need to be connected by couplings, chains or gears. The overall structure is complex and the transmission efficiency is low.

[0009] Limited operating conditions. Affected by the traditional structure, in the transportation of gas-carried solid materials, the channel size is large, and this type of mechanical crusher cannot be installed and used. Summary of the invention

[0010] In order to solve the shortcomings of the prior art such as complex structure, high cost, low efficiency and limited use, the present invention provides a fan blade crusher.

[0011] The technical solution adopted by the present invention to solve the above problems is: a fan blade crusher includes a fan blade device, a fixed seat, a transmission shaft, a frame, a bearing seat, a motor reducer and its electronic control device and related accessories. The fan blade device includes a blade, a blade seat and a connecting piece; the fixed seat includes a sealing device, a bottom plate, a cylinder and a flange; the frame includes a double flange, a cylinder, a flange, and a rib plate; the bearing seat includes a radial seat, a tapered roller bearing, an axial seat, a thrust bearing, a cover plate, a sealing piece, an oil cup and a connecting piece.

[0012] The fan blade crusher of the present invention is a cantilever structure as a whole, with the fan blade device located at one end thereof and the motor reducer located at the other end. This structural design can conveniently extend one end of the fan blade crusher into the interior of the required equipment (equipment that needs to be crushed, usually the bottom of the wastewater spray drying tower, the same below), avoiding problems such as interference with the flow channel of the required equipment. The cantilever structure means that the support bearing is only arranged on one side of the fan blade device, and the fan blade device relies on the bearing seat and the motor reducer to jointly bear the load; the support bearing includes the bearing in the bearing seat and the bearing of the motor reducer. When the fan blade crusher of the present invention is in operation, the motor reducer is required for auxiliary support, especially when radial loads occur. The fan blade device is fixed at one end of the transmission shaft, and the other end is connected to the motor reducer. A bearing seat is installed in the middle, and a sealing device of the fixed seat is installed between the fan blade device and the bearing seat; this structural relationship is also a manifestation of the overall cantilever structure.

[0013] The relative relationship between the main structure and components of the present invention is as follows:

[0014] 1) The fan blade crusher is installed on the required equipment through a fixed seat, the fan blade device is located inside the required equipment, and the frame, bearing seat and motor reducer are located outside the required equipment, which are not affected by high temperature and corrosion of materials. The fan blade crusher is different from the traditional structure. Its transmission shaft is a cantilever structure, which is fixed in the bearing seat outside. The shaft extends into the required equipment to be crushed, and the fan blade device is driven by the rotation of the transmission shaft to crush the material.

[0015] 2) The fan device is fixed to one end of the transmission shaft through a connector. The blade is installed on the blade seat through a connector, and the blade seat is installed on the transmission shaft through a connector. The fan device is connected to the end of the transmission shaft through a key or thread, which can be easily installed and repaired. Each blade in the fan device is also detachable. This structural design improves the convenience of installation in large equipment. Each blade can easily enter the equipment through a small inspection door and be assembled to the blade seat inside the equipment to form a fan device with a huge rotation diameter.

[0016] 3) The fixed seat is installed on the required equipment, with the sealing device of the fixed seat facing the required equipment and the flange end of the fixed seat facing outward, that is, the direction of the motor reducer; the fixed seat seals the transmission shaft through the sealing device. The sealing device is installed in the center of the base plate, the base plate is installed at one end of the cylinder, and the flange is installed at the other end of the cylinder. The fixed seat can be installed on the required equipment by welding, bolting or riveting, and the installation depth is determined according to the requirements of the crushed material. The fixed seat is mainly used to fasten the entire fan crusher, so the installation position should have sufficient structural strength and rigidity. The sealing device is to isolate the material in the required equipment to prevent leakage of materials, pressure or temperature.

[0017] 4) Install the fan device, fixed seat, bearing seat and motor reducer on the transmission shaft in sequence. Because the transmission shaft transmits the power generated by the motor reducer to the fan device, the transmission shaft runs through various components; the fan device inside the required equipment is installed at one end of the transmission shaft, and the transmission shaft passes through the sealing device of the fixed seat and then reaches the outside of the required equipment. The transmission shaft is limited by the bearing set on the flange seat, and the other end of the transmission shaft is limited and transmits torque through the reducer.

[0018] 5) The frame is installed on the flange of the fixed seat through a double flange. The cylinder is installed on the back of the double flange, and several ribs are installed between the outer side of the cylinder and the double flange. The flange is installed on the other end of the cylinder. The main function of the frame is to fix the bearing seat and the motor reducer on the fixed seat, that is, the main weight of the equipment is directly transmitted through the frame and does not act on the bearing. The size of the frame is larger than the bearing seat and is set outside the bearing seat. This structural setting not only improves the heat dissipation capacity and disassembly convenience of the equipment, but also ensures the stability and safety of the equipment.

[0019] 6) The bearing seat is installed on the double flange of the frame through the radial seat, and the transmission shaft is installed inside the bearing seat. The seal and tapered roller bearing are installed in sequence inside the radial seat, and the axial seat is installed in reverse at the end of the radial seat. The thrust bearing and seal are installed in sequence inside the axial seat, and the cover plate is installed at the end of the axial seat. These components should be installed in conjunction with the transmission shaft to ensure flexible rotation between the components of the fan blade crusher and reduce internal resistance.

[0020] 7) The motor reducer is installed on the flange of the frame, and the output shaft of the motor reducer is installed on the other end of the transmission shaft. The structural feature of the fan blade crusher is that the torque is input at one end and the output torque at the other end provides power for material crushing.

[0021] The fan blade device of the present invention is a multi-blade fan structure, and the blades are installed on the blade seat through a connecting piece. The number of blades is 2 to 8 and is evenly distributed along the circumference. The fan structure can ensure a large range of crushing areas; the connecting piece is easy to install and disassemble; the number of blades cannot be 1, and the rotation is unstable. When the number of blades exceeds 8, the inside is too dense, the crushing force is reduced, and the material is easily enriched and causes blockage; the blades are evenly distributed along the circumference, which is conducive to the stable operation of the equipment rotation and reduces its own imbalance.

[0022] In particular, the angle between the blades of the fan device and each flange surface is 0 to 30°. When it is 0°, the blades are arranged horizontally, and the crushing force is the largest at this time, but the disturbance force is approximately zero; as the angle continues to increase, the crushing force decreases and the disturbance force increases; when the angle is greater than 30°, the disturbance force begins to increase rapidly, but the crushing force has been reduced to half, and the rigidity of the blades is affected by the impact of the material, so the thickness of the blades needs to be increased, which does not conform to the concept of energy saving. The shape of the blade is preferably slat-shaped, and contour plates such as quadratic function curves and hyperbolas can also be used. In order to reduce energy consumption and improve the crushing effect, a number of pressure relief holes are usually opened in the middle of the blades with large output; the pressure relief holes can be circular, elliptical or oblong.

[0023] The fixing seat is a cylindrical barrel with a flange. The fixing seat is installed on the required equipment through its cylindrical body. The installation depth of the fan crusher can be adjusted by changing the position of the barrel. The cylindrical barrel structure is conducive to molding, better force, and convenient to adjust the installation depth. In heavy industry, the fixing seat is usually welded directly to the required equipment. When the fan crusher needs to be repaired or replaced, because the fixing seat is retained, the equipment does not need to be positioned again, which improves efficiency; at the same time, the welding structure also avoids the material leakage problem that may occur in the flange connection.

[0024] Several observation holes are set around the cylindrical body of the fixed seat. The functions of the observation holes include observing the reliability of the sealing device, cleaning and heat dissipation. Taking the spray drying tower as an example, the internal temperature of the tower is usually 200℃~350℃; a gap is set between the bearing seat and the fixed seat to reduce the thermal impact; and a certain amount of heat is transferred outward through the transmission shaft. These observation holes can reduce the impact of high temperature on the bearing.

[0025] The transmission shaft has an inner hole at one end for connecting with the output shaft of the reducer. The other end is a multi-step circular shaft with a cone in the middle. The function of the cone is that when the sealing device fails, the leaked material diffuses and flows outward along the cone shaft to avoid falling into the bearing seal pair; the stepped shaft is easy to install and realize the function. The shaft diameter of the multi-step circular shaft decreases from the inside to the outside, and the shaft diameter on the installation side of the tapered roller bearing decreases, that is, the installation shaft diameter of the tapered roller bearing> the sealing shaft diameter of the sealing device> the installation shaft diameter of the blade seat. This structure is conducive to the positioning and function realization of each component. At the same time, when the end fan blade device is impacted, the larger diameter at the bearing can withstand a greater load.

[0026] The double flange of the frame is a disc structure with two inner and outer flange holes, and a circle of discharge holes is evenly distributed along the circumference between the inner and outer flange holes. The outer flange holes of the double flange are connected to the fixed seat, and the inner flange holes are connected to the bearing seat; the discharge holes between the inner and outer flange holes are used to discharge the leaked materials from the fixed seat after the sealing device fails.

[0027] The cylinder of the frame is installed on the back of the double flange and is located between the two sets of flange holes. The cylinder is provided with several process holes along the circumference. The cylinder is a cylindrical structure with good performance. The cylinder is as large as possible to ensure strength. The process holes along the circumference of the cylinder are used for disassembly and oiling of the internal bearing seat. Several ribs are set between the cylinder and the double flange, and lifting holes can be set on the ribs. A flange is installed at the other end of the cylinder, and the flange is used to fix the motor reducer.

[0028] In order to ensure the performance of the equipment and reduce internal resistance and vibration, it is necessary to ensure the straightness of the reducer output shaft and the transmission shaft. Because the transmission shaft is installed in the bearing, the bearing is installed on the frame by the bearing seat, and its axis is perpendicular to the fixed flange surface; the reducer is fixed on the frame, and the axis of the reducer output shaft is also perpendicular to the fixed surface; therefore, the inner and outer flange surfaces of the double flange in the frame and the flange surface of the other side flange are required to be parallel to each other.

[0029] Different from the traditional structure, the bearing seat of the present invention is a flange structure, and the whole is a rotating body. This structure is consistent with the main body of the fan blade crusher, which is convenient for function and installation. A tapered roller bearing and a thrust bearing are installed inside the bearing seat; the tapered roller bearing is used to provide radial force and unidirectional axial force, and the thrust bearing is used to provide axial force in another direction. When the transmission shaft is subjected to axial force from the reducer to the fan blade device, it is directly transmitted to the tapered roller bearing through the shaft shoulder, and then transmitted to the frame by the bearing through the bearing seat; when the transmission shaft is subjected to axial force from the fan blade device to the reducer, it is directly transmitted to the thrust bearing through the shaft shoulder, and then transmitted to the frame by the thrust bearing through the bearing seat; the crushing force of the fan blade device is transmitted to the tapered roller bearing through the transmission shaft, and then transmitted to the bearing seat and the frame.

[0030] Based on the overall structure of the present invention, the radial seat and the axial seat of the bearing seat are both circular flange structures, which are easy to install and have better force bearing capacity; because the axial seat is fixed on the radial seat, and the radial seat needs to be fixed on the frame, the radial seat needs to be installed through the frame, that is, installation process holes need to be set on the cylinder of the frame. The number of flange holes of the radial seat is the same as the number of process holes along the circumference of the cylinder of the frame, and they correspond.

[0031] The inner ring of the tapered roller bearing is installed on the transmission shaft, and the outer side of the inner ring is positioned with the shoulder of the transmission shaft; the outer ring is installed in the inner hole of the radial seat, and the outer side of the outer ring is positioned with the inner shoulder of the radial seat. This structure can realize the transmission of radial force and unidirectional axial force.

[0032] The shaft ring of the thrust bearing is installed on the transmission shaft, and the shaft ring is positioned with the transmission shaft shoulder, that is, it is axially close to the transmission shaft shoulder and radially fixed on the transmission shaft; the seat ring is installed in the axial seat, and the inner hole of the seat ring and the shaft, the outer ring and the axial seat do not contact, and are not positioned.

[0033] According to the above structural description, the inner ring of the tapered roller bearing and the shaft ring of the thrust bearing are respectively installed on both sides of the same shaft shoulder of the transmission shaft. This structure can not only reduce the overall structural size, but also make it more convenient to lubricate the bearing cavities of the two bearings together.

[0034] The inner side of the radial seat and the outer side of the axial seat are each provided with a sealing cavity for installing the seal; the radial seat sealing cavity and the bearing cavity are on the same side, both inside; the thrust bearing is installed in the axial seat, so the sealing cavity of the axial seat and the bearing cavity are located on both sides respectively; because the seal of the axial seat is on the outside, a gland is required to be installed on the outside. In order to facilitate the removal of the seal, process holes should be set at the radial seat and axial seat sealing ring positions.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] ①Using rotating wind blades for crushing, the blade size can be easily increased, which can achieve material crushing and disturbance in a large area.

[0037] ②Simple structure, good manufacturing process and low cost. It adopts a simple cantilever structure, with only one tapered roller bearing and one thrust bearing inside. The motor reducer is directly connected to the transmission shaft, which is simple and efficient.

[0038] ③It can be produced in a standardized manner, can be scaled up, and is suitable for spray drying systems. Based on a simple structure, the product is easy to produce in a standardized manner; the fan device installed in the equipment occupies a small volume, and the area can be adjusted according to the size of the fan.
