Description

The present invention is a vertical lever pressurized powder grinding machine, in particular, it refers to a powder grinding machine which uses the principle of leverage to make the inner grinding wheel press against the outer grinding wheel to form a preset pressure, thereby improving the grinding efficiency, reducing noise and reducing the loss of the grinding wheel. machine.

In recent years, due to the improvement of living standards, the requirements for the quality of industrial products have become increasingly stringent, especially after people's awareness of environmental protection has increased and the GMP standards for food and drug manufacturing ("Drug Production and Management Regulations") have been formulated. The following: a. composition, b. noise, c. iron content (the main source is the loss of grinding wheel), d. temperature, e. pollution, etc. The demand for a grinding machine with strict GMP standards is even more urgent. So far, not only does the country not have the ability to manufacture this kind of grinding machine that can pass the GMP inspection, even abroad, there are few such qualified machines.

In addition, a well-designed grinding machine must also consider five major factors: a. torque, b. centrifugal force, c. destructive force, d. temperature, e. noise, and there is an inseparable relationship between the five types of factors. Or when the drive shaft transmits energy to the mill, it first generates torque, and then the torque forms centrifugal force. After the centrifugal force is transmitted to the grinding wheel, the gravity of the grinding wheel forms the destructive force required for grinding; while generating destructive force, it also brings temperature. Problems with elevated and increased noise. All factors are interlinked and cannot be ignored. The design of the early grinding machine is that the motor speed is fixed, so the input torque is also fixed, and the corresponding destructive force is also fixed. The well-known Raymond Ring-Roller Mill (Raymond Ring-Roller Mill) belongs to this type. Once this type of grinding machine has insufficient destructive power, or needs to increase production capacity based on certain considerations, the only way to increase torque is to replace the motor; , it tends to cause the crushed raw materials to be squeezed into flakes and cannot be effectively ground, and excessive crushing pressure is more likely to cause grinding wheel or machine wear, increased noise, increased temperature, and rearrangement of raw material crystallization And other problems, on the contrary, it will cause greater losses, let alone the improvement of production capacity.

Although the applicant has obtained Taiwan's No. 21011 model patent (US 3,955,766), the 24332 model patent (US 4,682,738) and the No. 42355 invention patent, the grinding particles (It has reached more than 13,000 mesh), grindable materials and production capacity have all been greatly improved, but they still cannot fully meet the strict requirements of GMP. Moreover, if a hard object is encountered during the grinding process, the inner grinding wheel will be pushed away. After the inner grinding wheel crosses the obstacle, it will rebound quickly and hit the outer grinding wheel, which becomes the main reason for the loss of the grinding wheel.

In view of the fact that the inventor is familiar with the grinder and the grinding wheel loss of the above-mentioned patented grinder, the speed cannot be changed, and the GMP standard cannot be met, so the inventor proposes the vertical lever pressurized grinder of the present invention.

The main purpose of the present invention is to provide a vertical lever pressurized powder grinding machine that meets the GMP standard.

Another object of the present invention is to provide a vertical lever pressurized pulverizer that utilizes multi-stage speed change, even stepless speed change, to meet the crushing pressure requirements of different raw materials.

Yet another object of the present invention is to provide a vertical lever pressurized powder grinder which utilizes the principle of spring tension and leverage to make the inner grinding wheel press against the outer grinding wheel due to pre-applied pressure to prevent wear and tear due to collision.

Another object of the present invention is to provide a vertical lever pressurized pulverizer that can obtain high crushing pressure at low rotational speed, increase production capacity and reduce noise.

A further object of the present invention is to provide a vertical lever pressurized pulverizer that utilizes the design of an isolated separation chamber, which can increase the separation effect and prevent the temperature of the raw material from rising.

Another object of the present invention is to provide a vertical lever pressurized powder grinder which utilizes self-aligning bolts to adjust and fix the center of the outer grinding wheel to make the grinding more stable.

The vertical lever pressurized pulverizing machine of the present invention mainly includes components such as a powder suction and feeding device, a separating device, a grinding device, a lever pressurizing member, a speed change mechanism, and a transmission device. The grinding device further includes an integrally formed outer grinding wheel, a centrifugal disc and multiple sets of inner grinding wheels. A lever pressing member is provided under the spindle of the inner grinding wheel, which includes a tension spring to provide the required pressure for the lever pressing member. pressure.

Hereinafter, the present invention will be described in detail through a preferred embodiment and with reference to the accompanying drawings.

As shown in the accompanying drawings, the vertical lever pressurized powder grinding machine 10 of the present invention mainly includes a fan motor M, a body, a powder suction and feeding device, a separator 30, a grinding device, a speed change and a transmission mechanism, and a powder collecting device 80. and other important components. The structure, function and working principle of the above-mentioned important components will now be described in detail in conjunction with the accompanying drawings.

As shown in FIG. 2 , the fuselage of the grinder 10 is composed of a top cover plate 12 , an upper fuselage 13 , a middle fuselage 14 , a lower fuselage 15 and a fuselage base 16 . A motor support 11 is installed on the top cover plate 12 for supporting an upright fan motor M. As shown in FIG. The rotating shaft of the motor M passes through the top cover plate 12 from top to bottom and extends into the upper body 13 and is connected with the fan main shaft 21 . The fan main shaft 21 is divided into an upper main shaft and a lower main shaft, which are connected with a shaft coupling therebetween. The fan blade 20 is installed on the fan main shaft 21 , thereby forming a powder suction and delivery device in the upper fuselage 13 . The upper fuselage 13 has a fan air inlet 62 at the bottom, and an air outlet 63 at the side to communicate with the powder feeding pipe 81 .

The fan main shaft 21 continues to extend downwards through the fan air inlet 62 and then enters the middle fuselage 14 to install the separator 30, and then continues to extend to the lower fuselage 15; the upper and lower ends of the main shaft 21 are provided with some thrust bearings, and the middle section Several ball bearings are also provided.

As shown in FIGS. 3 and 4 , the separator 30 includes a shaft sleeve 31 , a plurality of separating vanes 32 , a fixed cover 33 , two movable cover 34 and 35 , a baffle 36 and other main components. Wherein the fixed cover plate 33 is a thin plate that is framed into a semi-cylindrical shape, its upper edge is fixed on the periphery of the fan air inlet 62, and its front is connected with two movable cover plates of about a quarter cylinder shape. 34, 35 are connected to form a separation chamber, in which the separator 30 is placed. The aforementioned axle sleeve 31 is about a hollow cylinder, and a rotating disk 312 is fixedly mounted on the outside of the axle sleeve 31. There are a plurality of mounting holes 311 equally divided on the rotating disk 312. The above-mentioned plurality of rectangular separation blades 32 pass through one of them. The side locking portions 321 are radially arranged and embedded in the mounting holes 311 of the turntable 312 . A baffle 36 is also installed at the bottom of the shaft sleeve 31 . Since the separator 30 is placed in an isolated separation chamber, the air and space required for stirring are relatively small, and accordingly the required horsepower of the fan motor M is also relatively small. Furthermore, due to the isolation effect of the separation chamber, the high temperature generated by the grinding will not be brought into the separation chamber, and because the motor M rotates within a small range, it is not easy to generate noise.

As shown in each figure, the grinding device positioned in the lower fuselage 15 mainly includes an integrally formed outer mill 43, a centrifugal disc 44, and multiple groups of internal grinding wheels 43 mounted on the centrifugal disc 44 (the present embodiment is Three groups) and other important components. Wherein the outer grinding powder 40 is a basin-shaped body with a central hole, which is integrally formed by an alloy, and is arranged on the inner flange 17 of the upper half of the lower fuselage 15, and is horizontally adjusted by four sets of centering bolts 41 around it. Center position and fix it; In the vertical direction, utilize a plurality of bolts 402 to pass through the side wall of the flange 17 and the outer grinding wheel 40 from the bottom and lock a bushing 401, thereby the outer grinding wheel 40 is firmly fixed, with Grinds smoothly. The above-mentioned four sets of self-aligning bolts 41 are each two as a group, and each self-aligning bolt 41 is equipped with a locking nut. When the outer grinding wheel 40 is placed on the inner flange 17 of the lower body 15, the dial can be Calculate the center using a table or other methods, so that the center of the inner diameter of the outer grinding wheel 40 can coincide with the center of rotation of the centrifugal disc 44, and the coincidence of the two centers can be adjusted using the self-aligning screw 41. After the center is adjusted, each self-aligning bolt 41 should Tighten the locking nut to prevent the self-aligning bolt 41 from loosening, so as to ensure that the outer grinding wheel 40 will not be deflected. In addition, the outer grinding wheel 40 has a groove 403 in the radial direction at the intersection of the vertical wall surface and the horizontal wall surface on its inner side. When reaching the bottom of the groove 403, it means that the service life of the outer grinding wheel 40 has been reached, and it should be replaced immediately to prevent the outer grinding wheel 40 from being collapsed suddenly due to excessive use.

The above-mentioned centrifugal disk 44 is installed on the main shaft cylinder 58 (detailed later), and around the disk surface, corresponding to the number of inner grinding wheels 43 (three sets in this example), a plurality of pivot seats 45 are equidistantly arranged. The pivotal seat 45 is a cylinder with a U-shaped cross section, with elongated holes 46 on both side walls, and a gap at the bottom outer end for installing the extension rod 47 of the pivotal portion 421 . The inner grinding wheel mandrel 42 is connected to the inner grinding wheel 43 at its upper end, and an approximately square column-shaped pivot joint 421 is installed in the center of the lower end. There is a pivot joint hole 422 on the pivot joint 421 for the strip of the pivot joint seat 45 The hole 46 is pivotally connected. A plurality of tapered bearings are also arranged between the inner grinding wheel 43 and the spindle 42, so that the inner grinding wheel 43 can run smoothly. The upper and lower ends of the inner grinding wheel 43 are also provided with dustproof covers. As shown in FIG. 10 , extension rods 47 are installed below each pivot joint 421 and are divided into an L-shaped body and an inverted L-shaped body, wherein the vertical portion of the L-shaped body is connected to the lower end of the pivot joint portion 421 for Its horizontal portion is connected with the horizontal portion of another inverted L-shaped body, so that the horizontal portion of the two can be set in an outwardly extending state, so that the vertical portion of the inverted L-shaped body lower end can be compared with the main shaft cylinder 58 large spacing. The end of the vertical portion of the inverted L-shaped body in the extension rod 47 is provided with an adjusting bolt 49 , and a tension spring 48 is stretched between the end of the bolt 49 and the main shaft cylinder 58 .

The function of the tension spring 48 is to enable the inner grinding wheel 43 to form a preset pressure by leverage, so that the inner grinding wheel 43 can always maintain an appropriate pressure against the outer grinding wheel 40 . Since the fulcrum of the inner grinding wheel 43 is at the elongated hole 46, it belongs to the second type of lever with the fulcrum in the middle, so the magnification of the lever is the ratio of the length of the extension rod 47 below the fulcrum to the length of the inner grinding wheel mandrel 42 above the fulcrum, Therefore, the extension rod 47 should be extended as far as possible to obtain better efficiency. However, if the pressure applied to the inner grinding wheel 43 is too large, the starting load will increase, thus requiring higher horse power to run, so the size of the relevant parts must be properly selected, and the position of the fulcrum should be based on the required crushing force. To design, not static.

Speed change and transmission device are another key point of the present invention. The design of the present invention can adopt three kinds of transmission modes: a. The rotational speed of the motor is fixed, and the crushing pressure of the grinder is fixed. b. The motor speed is fixed, the grinder has a speed change mechanism, and the crushing pressure of the grinder is variable. c. Using a variable speed motor, the crushing pressure of the grinder is variable. Among them, type a is the traditional power supply method. Due to its fixed crushing pressure, the scope of application of its raw materials is limited. Therefore, as long as there are slight changes in temperature, humidity, materials, etc., the best production effect cannot be achieved, let alone Suitable for other kinds of raw materials. In the past, producers never considered the change of crushing pressure, and used it blindly in the design, so they only used this transmission mode for a long time. As for type c, due to the use of variable speed motors, the best output horsepower can be determined at any time according to the material, grinding conditions, and raw materials. It may be that type b is more popular with users, so this embodiment is described according to this type of transmission mode.

As shown in Figures 1 and 2, after the power is transmitted from the motor (not shown in the figure), the first driving belt shaft set on the motor spindle transmits the power to the input set on the gearbox 50 through several belts 54 The first driven pulley 51 on the end, the gearbox 50 can select the appropriate rotating speed by means of the shift lever 53, after the rotating speed is adjusted, the power is transmitted from the second driving pulley 52 at the output end of the gearbox 50, and the power is transmitted by several belts 55. Given the second driven pulley 56 provided on the main shaft 57, the main shaft 57 drives the centrifugal disc 44 and the main shaft barrel 58 to rotate simultaneously.

As shown in Figure 2, the lower section of the fuselage 15 is provided with an air inlet 64 along the tangential direction on its side to connect the recovery pipe 82, and the bottom of the lower section of the fuselage 15 is equipped with a slag discharge pipe 65 extending outwards beyond the fuselage base 16 . On the middle fuselage 14 and the lower fuselage 15, movable doors 60, 61 are respectively provided. Wherein the larger movable door 60 is facing the movable cover plates 34, 35 of the separator 30, so as to cooperate with the opening of the cover plates 34, 35 to carry out loading and unloading of the separating blade 32, cleaning and repair or maintenance of the separator 30. In addition, the dodge door 60 also has the functions of monitoring, maintaining and cleaning the grinding device. The small dodge door 61 is located on the lower fuselage 15 and can be used to adjust the adjusting bolt 49 to set the tension of the tension spring 48. In addition, it can also monitor the positional relationship between the centrifugal disc 44 and the inner grinding wheel spindle 42. .

As shown in Figures 5, 6, and 7, at the top of the outer grinding wheel 40, between the lower fuselage 15 and the middle fuselage 14, several wind deflectors 70 are provided. The top of the wind deflector 70 is approximately inclined, which can prevent The ground powder accumulates on it. In addition, a plurality of tuyeres 66 facing outward and upward are provided on the centrifugal disc 44 , and a plurality of double-layered inclined plates 67 are provided on the wall of the outer grinding wheel 40 on the periphery of the centrifugal disc 44 . The effect of this mouldboard 67 is to drive the ground powder to be sent evenly into the upper and lower layers between the inner and outer grinding wheels 43 and 40, so as to achieve more uniform grinding and prevent the accumulation of raw materials. As for the function of the tuyere 66, it is to loosen the raw material, so as to avoid the "bridging" phenomenon of stacking and crowding of the raw material, so that it cannot be ground innumerably.

As shown in Figure 1, the grinder of the present invention usually They are all used together with the powder collecting device 80 and the feeding device. The feeding device includes a feeder 86 directly connected to the feed port 18 on the grinder 10, and a raw material feeding barrel 19 connected to the feeder. The feeder 86 is also equipped with two groups of electromagnets (stronger magnetism) at its entrance to remove magnetic impurities such as iron filings and iron powder in the raw materials. The powder collecting device 80 includes a vortex powder feeding pipe 81 connected to the air outlet 63 of the upper fuselage 13 and extending upwards, and two pipelines connected to the recovery port 64 on the middle fuselage 14 - a recovery pipe 82 and a cooling pipe 83, and parts such as finished product collection pipe 84 and dust collection cover 85. The ground powder passes through the powder suction device, and after the air outlet 63 is discharged from the powder grinder 10, it flows through the powder feeding pipe 81 and enters the powder collecting device 80, and those whose particle size meets the requirements are discharged through the finished product collection pipe 84 for subsequent processes such as packaging. ; Particle does not meet the requirements of the reclaimer pipe 82 by fan blown into the middle section of the fuselage 14, re-grinding. And dust then falls in the dust collection cover 85 that needs regular cleaning and maintenance. The operation of the present invention is further described below.

Because the present invention adopts the grinding mode of forming the preset pressure by the elastic force of the spring 48, so before starting the machine, the raw material to be ground must be put into the outer grinding wheel 40, and the amount put in is about three times the height of the outer grinding wheel 40. 1/1/, in order to avoid inner grinding wheel 43 and outer grinding wheel 40 from wearing and tearing because of idle grinding. When starting up, the fan motor M should be started first, and then the host motor should be turned on. After the host motor starts running, power is transmitted to the first driven pulley 51, the gearbox 50, the second driving pulley 52, the second driven pulley 56 successively from the first driving pulley, and then to the main shaft 57. After the main shaft 57 rotates, it drives the centrifugal disc 44 and the main shaft barrel 58 mounted on it to rotate. At this time, the inner grinding wheel 43 starts to revolve around the main shaft 57 and the main shaft barrel 58 along the inner wall of the outer grinding wheel 40 to produce grinding action. grinding wheel, and due to the friction between the contact surfaces, the inner grinding wheel 43 rotates around the inner grinding wheel mandrel 42. Because the extension rod 47 at the bottom of the inner grinding wheel mandrel 42 is pulled by the tension spring 48, the inner grinding wheel 43 can always be kept against the outer grinding wheel 40, so that high-efficiency grinding can prevent the inner grinding wheel 43 from colliding with the outer grinding wheel 40. cause loss. Therefore, not only the noise is small but also the service life of the grinding wheel can be extended.

After the motor is started, the air is sent into the pulverizer 10 from the recovery port 64, and is blown upwards through the air duct outside the outer grinding wheel 40, and the eddy current acceleration is formed by the wind deflectors 70. At this time, the raw material stored in the feed barrel 19 is controlled by the feeder 86 at a feed rate. Since the raw material particles are very large, they will not be affected by the rising vortex and directly fall into the outer grinding wheel 40 and the centrifugal disc 44. The centrifugal force generated by the rotation of the centrifugal disc 44 and the movement of the inner grinding wheel 43 combined with the assistance of the upper moldboard 67 and the tuyere 66 allow the raw material to be squeezed between the outer grinding wheel 40 and the inner grinding wheel 43 to grind the raw material , crushed. Due to the extremely small weight of the ground powder, it can rise with the vortex airflow and enter the separation chamber formed by the fixed cover plate 33 and the movable cover plate 34, 35. Due to the centrifugal force, the weight is relatively large (that is, the particle size is large) ) powder is located outside the vortex and rises along the inner wall of the fuselage, while powder with a smaller weight is located inside the vortex and rises along the fan main shaft 21, and when it reaches the bottom of the separator 30, it is blocked by the baffle 36 and goes upward At this time, through the suction effect of the powder suction device, the powder is separated by the separator 30 and then inhaled by the fan air inlet 62, and then discharged into the powder feeding pipe 81 through the air outlet 63.

During the process of staying in the separator 30, the powder particles are separated by the rotating separation blade 30, and a small amount of powder particles with a slightly larger particle size are crushed or knocked down to the grinding device for further grinding. The more the number of separating blades installed, the finer the obtained particle powder. A small amount of impurities that are heavy and difficult to crush or raw materials that are fed too much will fall to the bottom of the lower fuselage 15 through the wind deflector 70 under its own gravity and centrifugal action, and then be swept by the outside of the main shaft tube 58. Plate 71 sweeps it out of slag discharge pipe 65 . When the power is off or shut down, since the air supply and blowing have stopped, the raw materials and ground powder particles will fall due to their own gravity, and a small part will fall to the bottom of the lower fuselage 15 through the wind deflector plate 70, borrow the main shaft tube 58 The inertia of the machine drives the sweeping plate 71 to sweep it out from the slag discharge pipe 65. As for the powder particles falling in the outer grinding wheel 40, it can be used as the base material for the next startup without any impact on the machine. Therefore, once the power is restored, , to restart immediately.

The gearbox 50 in the present invention has two usages. One is to divide the speed into several sections, such as four kinds of high speed, medium speed, medium low speed and low speed. pressure. The other is to adjust different speeds according to the needs of the grinding process, or to provide the most suitable pressure and speed for the crushing pressure required by the same raw material in different seasons or under different conditions such as temperature, humidity, and viscosity. Make the present invention can reach the highest production capacity. General raw materials can be roughly divided into three categories, that is, high fiber suitable for high speed, general fiber and concentrated products suitable for medium speed, minerals and viscous colloid suitable for low speed, etc. Therefore, appropriate materials can be converted according to the above-mentioned different materials. Speed to achieve the best grinding effect.

When grinding some special raw materials, such as herbs, medicaments and chemical raw materials, they need to be controlled at low temperature, and even need to control their humidity in some cases, so the present invention can also connect the recovery pipe 82 on the recovery port 64. Connect a cooling pipe 83, so that importing freeze-drying air is cooled as required, or even pass through with liquid nitrogen to overcome Grinding barriers for viscous substances, etc. The flow rate of the gas input can be controlled by a valve.

The above-described embodiments are more suitable for the grinding of non-crystalline substances, and for crystalline substances, when grinding, the inner grinding wheel 43 and the outer grinding wheel 40 do not need to be in direct contact, and only need to squeeze the raw material moderately to achieve crushing effect, so in this case the second embodiment of the mill as shown in Figure 8 can be used to obtain the best effect. The structural features and the differences between the two embodiments are described in detail below.

Since the inner grinding wheel 43 does not need to be in contact with the outer grinding wheel 40 in this case, the present embodiment adopts a higher pivotal seat 75 on the centrifugal disc 44, as shown in Figure 8, the pivotal seat The position of the elongated hole 76 on the 75 is also lower than that of the first embodiment, and a baffle plate 77 is also arranged on the outer surface of the pivot seat 75, and an adjusting screw 78 is arranged on it to adjust the inner grinding wheel 43 and the outer Gap between the grinding wheels 40, and ensure that there is no contact between the two, so that the raw materials such as crystals such as sugar and salt, minerals, chemical raw materials, medicaments and viscous crystals (such as resin) have higher grinding efficiency.

To sum up, the vertical lever pressurized powder grinding machine of the present invention not only has high grinding efficiency, but also can be applied to various materials, and the quality of powder products is high, and the industrial use value is high. There is no doubt about its practicability, and The technical scheme of the present invention also has nothing in the prior art, so it is novel.

The above-mentioned embodiments are cited for the convenience of describing the present invention, so the present invention is not limited thereto, and various transformation designs can be made on the basis of the basic features.
