Description

[0001] Technical field: [Upgraded grinder] is a hammer mill, and it is a newly launched medium-sized grinder equipment with a new upgraded type of corn feed crushing as an example (the case with a crushing main power of 22 kilowatts belongs to a medium-sized grinder). This grinder brings together all the advantages of existing grinders, eliminating the common problem of repeated crushing and heat generation and low output of the original grinder. It has added 7 upgraded technologies to achieve secondary high-efficiency crushing and secondary high-efficiency screening. The area of ​​the powder outlet of the crushing chamber has increased by 50%, and the internal resistance has been reduced by 1 / 3. The machine body can be moved independently for production, and the transportation cost can be reduced. The average production quantity and quality have been greatly improved. Compared with modern domestic and foreign advanced technologies, the production cost of replacing and upgrading the grinder has been reduced by 50%. It is an updated technology, and this technology has reached the leading level at home and abroad.

[0002] Background technology: At present, 80% of the powders and particles processed in the food, feed, chemical, building materials, non-metallic and other industries are produced by hammer mills. Although the processing and production costs are very high, it is indispensable because other crushers cannot replace it, which is why it has been favored by people and widely used. In order to produce high-quality products and reduce consumption, it is necessary to have a coarse crusher, a conveyor, a sifter for grading, then conveying, and then crushing again. A total of four equipments are required for a one-stop fixed position production line. As a result, the product quality is good, but the production cost is still very high, and multiple equipment investments are added. The workshop occupies too much area, human resources are wasted, energy consumption is extremely large, noise is loud, dust is high, the production environment for workers is extremely poor, there are many equipments, many maintenances, and more waste of working days. For product quality, people have been under the economic pressure of high consumption.

[0003] Invention content: The purpose of the present invention is to establish a new set of invention technologies in response to the above-mentioned technology and the economic pressure of high consumption, and to propose a new production equipment technology for a new type of medium-sized and large-scale upgraded crusher. Secondary crushing and secondary screening can be achieved during the crushing process. The powder outlet area of ​​the crushing chamber is increased by 50%, and the internal resistance is reduced by 1 / 3. The machine body can be moved independently for production, which greatly improves the production efficiency and easily completes the tasks of 4 devices. The machine can be fixed and moved to the side of the crushed material for production, reducing transportation costs, and can be reversed for production. The small-diameter single-screen crusher has a higher output by adding a new technology of blocking plates. The large diameter of the medium-sized crusher remains unchanged, and the side is widened to be a high-power device, which can achieve a strong production of extra-large flow. The new technology of blocking plates for other crushers or water-drop hammer crushers can improve the crushing efficiency. The new technology of blocking plates for the American 360-degree full-screen hammer crusher is more efficient than the water-drop type. The original production line remains unchanged, and the crusher is directly replaced and upgraded for production. The production efficiency is higher than the above two crushers, and the quality is better.

The blades are fixed on the long shaft by oblique staggered welding. The shaft is hollow, one end of the shaft is fixed on the main shaft of the variable speed motor, and the other end of the shaft is connected to the bearing connected to one end of the outer shell cylinder. When the variable speed motor is turned, the long shaft blades rotate obliquely, driving the powder particles in the feed port to move to the discharge port. The strong wind in the feed port is blocked by the powder filled with the oblique blades, realizing the air-off feeder 1 2, which is conducive to the subsequent windless powder falling into the vibrating screen for screening. One end of the 12-gate air feeder is installed in the middle and lower position on the center line of the front panel of the machine body. One end connected to the variable speed motor is connected to the bottom of the large baffle plate and tightly combined and then installed on the support plate of the large baffle plate.

[0017] Specific implementation method: The working principle of the medium-sized upgraded crusher crushing corn is taken as an example. The following example is combined with the accompanying drawings of the specification. Figure 1The working principle of the present invention is further explained, which is characterized in that: the upgraded crusher body 15 has the appearance of a medium-sized wardrobe, with an openable movable circular working door 26 on the front, a feed hopper 2 is installed on the upper part of the working door, and a 50 mm thick wood glue board pad is sandwiched in the middle of the thickened working door to make room for sifting out the powder 24, and a side screen frame iron plate 27, and a 360-degree side screen, which are fixed with long screws. The edge of the working door is 360 degrees recessed to sift out the powder channel, and the working door is closed. The side sieve powder passes through the groove and then passes through the positive screen frame 1 space to reach the large space. The positive screen frame 1 is composed of two blue ring iron plates, and the inner diameter has an arc-shaped groove that conforms to the material blocking plate. One is installed on the inner side of the working door frame on the front of the body, and is fastened with long screws 23 and long pad sleeves 22 to obtain a side screen 7 The powder is discharged through the 360° space channel of the circular iron of the screen frame and then reaches the large space. The other blue ring iron plate of the positive screen frame 1 is the same as the above, but is installed on the 19 combined plates. The combined iron plate is like a large blue ring. The lower part of the combined plate is cut into a polygon in an arc shape and is separated and welded and fixed on the large baffle plate with two round iron columns about 60 mm long to form a channel, and the combined iron plate is reinforced.

The working process is implemented as follows: corn feed particles enter the feed hopper, discharge downward, pass through the lower seasoning gate switch feed port, and then pass through the oblique channel to the barrel to reach the semi-hollow hammer frame dividing blade 4, and pass through the dividing blade 4 evenly through the hammer 3 to reach On the 360° positive screen, the motor 16 is directly connected to the main shaft to drive the semi-hollow hammer branch frame 4, and the hollow branch frame drives the hammers on the bracket to rotate at high speed. The crushed corn powder particles that meet the positive screen, including the particles of the left and right side sieve holes, are discharged out of the sieve. The large particles that are not discharged follow the high-speed rotating hammers and pass through the small hammers on the blocking plate 8. The high-speed rotating large particles hit one end of the small hammers on the blocking plate and are crushed positively, realizing secondary crushing, increasing the crushing efficiency and saving electricity. The positive screen, the blocking small concave sieve plate, and the left and right sieves are long sieve holes, which can increase the powder output rate, but there are also unqualified powder particles. The large and small powder particles are collected by the blocking plate 9 and discharged downward, and fall into the vibrating screen 10 through the inlet to the outlet of the air-locking feeder for shifting and vibrating screening to obtain high-quality and high-yield powder particles.Then it falls into the baffle plate 9 below and is collected and discharged downward to the finished product outlet 14 of the long hole screen. The outlet has a switch to cooperate with the work. The vibrating screen 10 is composed of several hollow shafts and combined screen walls to form two sloped screen frames, and a woven screen. It can be diverted on both sides. The corn powder particles that have not passed the vibrating screen enter the non-finished product outlet 11. In addition, the left circumferential side screen and the right circumferential side screen are installed on both sides of the positive screen in the grinding chamber, which can increase the powder discharge area and improve the powder discharge rate. There is a large baffle under the powder particles that pass through the vibrating screen to collect and discharge them. After passing the powder discharge switch, it reaches the finished product outlet of the long hole screen. A finished powder bag frame 35 is installed on the outlet. The bag frame can be connected to the suction duct of the original production line to transport the finished powder into normal production. This can reduce the cost of transformation.

See the attachment of the instruction manual. Figure 2 , Fig. 9 .

[0022] The above claim 3, which is a technical solution for secondary screening of powder particles by using a long hole screen, highlights the substantial features and significantly improved component composition and installation components and all the related contents, which limit the scope of the patent protection required.

[0023] 4. The upgraded grinder is a medium-sized grinder in the shape of a crushing corn feed example. Its cabinet-shaped powder discharge space is large. Technical solution: the existing technology grinder has a small space with a circumferential distance of only 50-100 mm from the outer edge of the body to the crushing chamber screen, and its width is the same as the width of the crushing chamber. The three-dimensional space powder discharge channel formed by the two items is small and has a large backwind pressure. It is necessary to install a suction fan pipeline to discharge the finished powder particles to work normally. The outstanding substantial characteristics and significant progress of this machine are characterized in that the outer edge of the cabinet-shaped machine is closed, and a large space with a large distance from the positive screen of the crushing chamber to the edge of the machine body can be obtained. The width is also increased by 3 times. The three-dimensional space formed by the two items is large, and the powder particles discharged are 20 times the space of the powder discharge channel of the existing grinder. The extremely small backwind pressure blocks the powder discharge of the sieve holes, and there is no need to install suction fans and pipelines, which can save production costs and improve the powder discharge rate. The upgraded grinder is a medium-sized grinder in the shape of a crushing corn feed example. The cabinet-shaped powder discharge space is large. The structural installation of the technical solution is: the positive screen of the crushing chamber of this machine is installed on the circular iron plate of the screen frame 1 inner diameter, the screen frame 1 is located at the center point of 600 mm from the vertical center line under the upper cover plate. The screen frame 1 is installed on the working door 26 frame with 23 long screws and 22 long gaskets, and is also installed on the upper iron plate on the front of the machine body. Another positive screen frame 1 is also connected to the corresponding combined iron plate 19 with 23 long screws and 22 long gaskets. The combined iron plate is connected with 20 angle irons. After the center position is determined, the other end of the angle iron 20 is fixed on the iron plates on both sides of the machine body. The crushing chamber is installed below the positive screen Collect two large materials 9, the upper end is welded and fixed to the inner side of the machine body, and the lower end is tightly fixed to the air-off feeder 12, so as to obtain a large surrounding space on the front. The side view is the same as the large combined space on the front, except that the isolation space for the circular die body of the motor and the space of the crushing chamber need to be subtracted, and the remaining space is the space for screening out the powder. Compared with the more than 20 times space for the space channel for screening out the powder in the prior art, the circular die body 18 for the motor is installed on the combined iron plate on the right side of the crushing chamber and fixed with several screws. See the instruction manual Figure 2 , Figure 6 , Figure 7 .In addition, if you want to increase the space, you can separate the upper cover to extend the space. If the extension exceeds the limit, there is no need to add a cover. The wind pressure in the large space will be smaller, which is beneficial for a higher 360° powder extraction rate of the positive screen.

[0024] The above claim 4 states that the machine body is cabinet-type and the technical solution of large powder outlet space is substantial and significant progress, describes the large space structure, and limits the scope of patent protection required by comparing with the entire content of the prior art.

[0025] 5. The upgraded grinder belongs to the medium grinder of the type of corn feed grinder. The technical solution for widening the grinding chamber: when the grinding chamber is widened to more than 200 mm, it is to use a variable-speed screw conveyor for center feeding. The screw conveyor is composed of a conveyor barrel and a spiral main shaft. The outstanding substantial feature and significant progress is that there are several discharge holes on the conveyor barrel. The purpose of several discharge holes is to ensure that the powder can evenly pass through the hammer bracket dividing blades 4 and reach the grinding chamber positive screen for grinding. The use of the screw conveyor for center feeding in cooperation with the hollow hammer bracket dividing blades 4 and the existing advanced technology water-drop hammer grinder top feeding can increase production by 35%. Because the water-drop grinder is top fed, the U-shaped positive screen has 30% fewer positive screens, and the powder screen holes are covered by the raw materials that have just entered, which seriously reduces production by 35%. Installation method: See the attached diagram of the working principle of the widened grinding chamber in the specification. Figure 3 , the widening of the crushing chamber has increased, 31 reinforced positive screens, installed in the lower part of the positive screen of the screen frame tightly combined, the two ends of the horizontal iron plate on the collar screen are fixed to the two ends of the positive screen frame, 33, the separation working door branch frame is made of angle iron frame, there are 4 moving wheel devices at the bottom of the bracket, the upper part is connected to the working door with screws, and the screws can be separated, 28, the screw conveyor is fixed on the circular bearing seat on the working door, 29, the circular bearing seat is fixed to the working door with screws, the bearing of the circular bearing seat is connected to the hollow support ring 38 of the hollow hammer frame, and the bearing seat of the separable bearing is installed on the hollow support frame at the other end. The backrest wheel is installed in the hollow support ring, and the backrest wheel is connected to the main shaft of the large motor. The large motor is upright and fixed on the combined iron plate. The combined iron plate is connected to several angle irons 20, which are respectively welded to the inside of the machine body after the center is aligned. 21 variable speed small motor is installed at one end of the propeller 28 feeding.

[0026] The above claim 5, the outstanding substantial features and remarkable progress of the grinding chamber widening technical solution, describes the installation of all components and the entire contents of the relationship that the original grinder remains unchanged and only the grinding chamber is widened to produce a high-power grinder, which limits the scope of the patent protection required.

Several circular sheet hammer brackets are installed on the main shaft. Each circular bracket has several shaft holes. The hammer shafts are installed in the shaft holes and protrude on the planes on both sides of the circular bracket. A hammer is installed on each side of the shaft. This installation causes too many circular hammer brackets, which increases the weight. The distance from the hammer hole to the tail end is long. The number of hammers is too large, and the weight is increased. Compared with the upgraded mill crushing chamber widening technology, and the above The invention is the same as the existing water drop type mill, except that: (1) there is no main shaft on the hammer bracket, which can reduce weight; (2) the milling chamber is widened. The circular sheet bracket without widening the milling chamber is hollow, and there are several small planes protruding on the outer edge for mounting the hammer shaft pin, which reduces the redundant edge planes and reduces weight. The number of circular sheet brackets is reduced, which reduces weight; (3) the circular sheet bracket itself has a large area of ​​solid, which can be hollowed out to reduce weight. Compared with the existing milling machine technology, the upgraded milling machine hammer bracket, the material distribution blades and all the hammers can reduce 1 / 3 of the weight, achieving the goal of reducing the internal resistance by 1 / 3 of the weight. See the attached figure of the specification. Figure 3 The specific setting method of widening the hollow vertical plate bracket in the crushing chamber to reduce the internal resistance and the connection relationship with other components are explained as follows: the hollow hammer bracket 4 is composed of ① 4 material dividing blades; ② two hollow circular plate brackets; ③ a reinforcing connecting plate is installed in the middle of the material dividing blade or the hollow hammer bracket is used to strengthen the middle reinforcing connection, ④ a number of hammers; ⑤ a long shaft pin of the hammer; ⑥ a support ring to support the weight of the widened hammer frame, a hollow circular ring to support the bearing; ⑦ two circular bearing seats; ⑧ a pair of backrest wheels, a total of 8 items are installed, ① four material dividing blades 4 are installed and connected to the corresponding inner side of the hollow circular plate bracket and fixed by electric welding; ⑦ the bearing seats are respectively fixed on ⑥ the hollow circular rings 37 supporting the bearings; ⑥ the hollow circular rings are fixed on ④ the hollow circular plate hammer branch frame, and the outer diameter of the hollow circular plate branch frame Four protruding small planes have four holes for installing and connecting four long shaft pins of the hammer; ⑤ When the long shaft pin of the hammer passes through the hollow bracket, the four shaft pins connect several hammers ④, ⑥ A pair of backrest wheels are installed on the left side of the hollow support ring 37 and then connected to the 16 large motors. Compared with the existing water drop type crusher of the same column shape, the different characteristics are: 1. The distance from the original hammer hole to the tail end is longer, which can be shortened to reduce weight; 2. The four small planes with holes protruding from the edge of the circular sheet hammer frame reduce the excess weight on the edge, and there are many empty positions on the plane itself, and the emptying can reduce weight; 3. The number of hollow circular sheet hammer branches can be reduced, which can reduce weight. 4. There is no solid main shaft on the hammer bracket 4, which can reduce weight. The above four characteristics improve weight reduction, that is, reduce internal resistance and save power consumption

[0028] The description of the outstanding substantial features and remarkable progress of the technical solution for reducing internal resistance in claim 6 above, which reduces the support volume by 1 / 3 and the installation position relationship compared with the prior art, all defines the scope of the patent protection required.

[0029] 7. The upgraded grinder is a medium-sized grinder for crushing corn feed. The machine body mobile technical solution has substantial characteristics and significant progress. It is characterized by the fact that the medium-sized grinder of modern technology has a suction fan and a large pipeline connection on the machine body to work normally, and can only work in a fixed position and cannot move. Compared with the upgraded grinder, there is no suction fan and a large pipeline connection on the machine body, and the machine body can work alone. There are 4 fixed hooks on both sides of the machine body, like the moving wheels 17 of a rickshaw, and the wheel axle is installed in the hook. The machine body can be moved to the raw material for production by pushing it, reducing the transportation cost of transporting a large amount of powder. See attached Figure 1 , Figure 2 .

Screws 23 and 50 mm long bushings 22 are fixed on the combined iron plate 19, also on the same center line, so that the gap of about 3 mm at the intersection of the sieve 7 and the positive screen 6 at the 360-degree circumference can open the working door, the two half-body positive screen frames 1, the positive screen plate 6 and the material blocking plate 8 are installed, the motor 16 is directly connected to the main shaft 5 and extends into the crushing chamber, the hammer frame 4 and the hammer 3 are installed, the working door 26 is closed, and the motor 16 rotates the crushing chamber to work. The working process is implemented as follows: corn feed particles enter the feed hopper, discharge downward, pass through the lower seasoning door switch feed port, and then pass through the oblique channel to the barrel to reach the semi-hollow hammer frame dividing blade 4, and the dividing blade 4 passes evenly through the hammer 3 to reach the 360° positive screen, and the motor 16 is directly connected to the main shaft to drive the semi-hollow hammer branch frame 4 The hollow branch frame drives the hammers on the bracket to rotate at a high speed, and the crushed corn powder particles that meet the positive screen including the particles on the left and right side screen holes are discharged out of the screen. The large particles that are not discharged follow the high-speed rotating hammers and pass through the small hammers on the blocking plate 8. The large particles rotating at high speed hit one end of the small hammers on the blocking plate and are crushed positively, realizing secondary crushing, increasing the crushing efficiency and saving electricity. The positive screen and the blocking small concave screen plate and the left and right screens are long screen holes, which can increase the powder output rate, but there are also unqualified powder particles. The large and small powder particles are collected by the blocking plate 9 and discharged downward, and pass through the entrance to the air-locking feeder to the outlet and fall into the vibrating screen 10 for shifting vibration screening to obtain high-quality and high-yield powder particles, and then fall into the blocking plate 9 below to be collected and discharged downward to reach the long hole screen working finished product outlet 14.The outlet has a switch to work together. The vibrating screen 10 is composed of several hollow shafts and combined screen walls to form two sloped screen frames, and a woven screen. It can be diverted on both sides. The corn powder that has not passed the vibrating screen enters the non-finished product outlet 11. In addition, the left circumferential side screen and the right circumferential side screen are installed on both sides of the positive screen in the grinding chamber, which can increase the powder discharge area and improve the powder discharge rate. There is a large baffle under the powder that passes through the vibrating screen to collect the lower discharge, and it reaches the finished product outlet of the long hole screen through the powder discharge switch. The outlet is equipped with a finished powder bag frame 35. The bag frame can be connected to the suction duct of the original production line to transport the finished powder into normal production. This can reduce the cost of transformation. Combined with the attached drawings of the specification, the upgrade of the crusher for secondary crushing and secondary screening to improve the output quality, how to reduce the internal resistance, how to reduce the production cost and the widening technology of the grinding chamber, a total of 7 upgraded technical solutions are described as follows. , The above claims:

1. The technical solution adopted by the new invention to solve its technical problems has outstanding substantial features and remarkable progress, the combination of 1-38 technical components constituting the upgraded crusher and the description of the specific positions and relationships of the components with different names, as well as the entire description of the specific implementation method limit the scope of the patent protection required.

2. The upgraded crusher belongs to the medium-sized crusher in the form of a hammer crusher for crushing corn feed. Its blocking plate realizes the technical solution of secondary crushing. The technical solution of the blocking plate has outstanding substantial characteristics and remarkable progress. It is mainly composed of several small concave arc sieve plates with several small hammers protruding vertically in the middle. During the crushing work, one end of the side of the small hammers of the blocking plates can directly block the extremely fast rotating powder particles from being crushed again. The blocking plate realizes secondary crushing. The specific installation relationship and work are the same as those of the existing crushing chamber. The different feature is that the blocking plate is composed of a small concave arc sieve plate and several small hammers. See the blocking plate (Figure 3) in Figure 1 of the specification. There are several long holes slightly larger than the small hammers in the middle of the small concave arc sieve plate, and the small hammers pass vertically through the prepared long holes. The protruding 10mm position is fixed by electric welding to form an independent material blocking plate. The material group plate and the segmented positive screen are connected to form a full screen with a material blocking plate. The full screen can also be installed in sections on the positive screen frame 1. During the crushing operation, several large hammers drive the powder to rotate at high speed. After passing through several small concave arc screen plates and several small hammers, one end of the side of the small hammers directly blocks the high-speed rotating powder and is crushed again, achieving secondary crushing and improving the crushing efficiency. Other crushers or water-drop hammer crushers have a higher crushing rate by adding the new technology of material blocking plates. The American 360-degree full-screen hammer crusher has a higher output by adding the new technology of material blocking plates. The upgraded crusher has higher production efficiency than the former two. According to production needs, the machine can be decomposed into multiple series, and the upgraded technology can form an independent crusher with 1 or more technical solutions. The above claim 2 describes the outstanding substantial features and remarkable progress of the secondary crushing technical solution achieved by the material blocking plate, as well as the structure and installation of the material blocking plate and its ability to be decomposed into multiple series. The entire content of the description limits the scope of the patent protection required.

3. The upgraded mill is a medium-sized mill that uses a hammer mill to crush corn feed. It uses a long-hole screen to screen the powder particles for secondary screening. In order to further improve the output and quality, this machine has outstanding substantial features and significant improvements, which are characterized by The positive screen, the left screen, the right screen, and the three screens are replaced with long hole screens. Compared with the existing technology, this machine is characterized by a 50% increase in the powder outlet area. The large and small particles of the long hole screen are crushed and collected by the large baffle plate and then passed through the wind-off feeder 12 installed in the machine body to reach the vibrating woven screen 10 in the machine body for secondary screening, and then collected by the large baffle plate below to reach the finished product outlet of the long hole screen. The vibrating woven screen is equipped with two layers of screens, and two positive products can be obtained by quickly circulating in this cycle. The whole process is realized, the secondary screening is improved, and the crushed material is not repeatedly crushed, does not generate heat, and flows smoothly. Large quantity, excellent product quality, and extremely high production efficiency. The positive screen accessories are characterized by being made of several small concave arc-shaped screens and segmented positive screens to form an overall 360-degree full screen. There are several 360-degree screen pressing screw holes on both sides of the screen. Several chute seats are fixed on the positive screen frame at both ends. Several large elongated holes for small hammer pieces are left in the middle of the small arc-shaped screen to allow the small hammer pieces to move in and out of the elongated holes. The vibrating woven screen 10 is formed by a hollow coupling and two screen walls forming a sloped screen frame combination. The woven screen is installed at the bottom of the two sloped screen frames to form a vibrating screen. One end of the vibrating screen is connected to a small connecting rod 32 with an adjustable distance. The small connecting rod connects the eccentric shaft wheel of the variable speed small electric shaft, and the variable speed small motor 21 is installed on the stand 34 on the right side of the body. In addition, the air-locking discharger 12 is uprightly installed with the second small variable speed motor 21. The air-locking discharger 12 is composed of ① an air-locking discharger shell sleeve, one end of the shell sleeve is connected to a blue ring, the blue ring is connected to the supporting large iron plate on the large material plate 9, and the other end is connected to the front panel of the body. There is a long feed port on the shell and a discharge port under the shell. Powders of different sizes pass through the air-locking discharge inlet and reach the discharge port under the shell when the material-dividing blade shaft rotates and moves to the shell, and then fall into the vibrating screen. On the woven screens of the two slopes, the powder contacts the woven screens on the slope and moves back and forth to vibrate, realizing secondary screening; ② In addition, there is a pulley at the lower end of the slope, and a long slide bar is below it to support the pulley on the screen frame to move back and forth. The slide bar is installed on the inner surface of the front panel of the machine body, and the other slide bar is installed on the corresponding large supporting iron plate in parallel to support the vibrating screen for secondary screening. In addition, a hanging rod support method can be used, in which a movable hanging rod is installed at the upper position of the two sides of the machine body, and the lower end of the hanging rod is connected to the inner ring of the movable wheel bearing under the screen frame, which can be movably lifted. The bearing housing does not contact the slide bar, and the connecting rod drives the screen frame to screen back and forth. ③ Several long blades on the inner surface of the air-off feeder are obliquely connected to the long hollow shaft. One end of the hollow shaft is connected to a small variable speed motor, and the other end is connected to the bearing in the outer shell to support the rotation work. See Figures 2 and 9 of the specification. The above claim 3, which is a technical solution for secondary screening of powder particles by using a long hole screen, highlights the substantial features and significantly improved component composition and installation components and all the related contents, which limit the scope of the patent protection required.

4. The upgraded grinder is a medium-sized grinder for crushing corn feed. Its appearance is cabinet-type and has a large powder discharge space. Technical solution: The existing technology grinder has a small space with a circumference of only 50-100 mm from the outer edge of the body to the grinding chamber screen. The width is the same as the width of the grinding chamber. The three-dimensional powder discharge channel formed by the two items needs to be installed with a suction fan duct to discharge the finished powder particles in order to work normally because of the small space and high backwind pressure. The outstanding substantial features and significant progress of this machine are characterized by The outer edge of the machine is cabinet-shaped and closed, so a large space can be obtained from the circumference of the main screen of the grinding chamber to the edge of the machine body, and the width is also increased by 3 times. The three-dimensional space formed by the two items is large, and the space for discharging powder particles is 20 times that of the existing powder outlet channel of the grinder. The ultra-small reverse wind pressure blocks the powder outlet of the sieve holes, and there is no need to install suction fans and pipelines, which can save production costs and improve the powder outlet rate. The upgraded grinder belongs to the medium-sized grinder in the form of a corn feed crusher. The cabinet-shaped powder outlet space is large. The structural installation of the technical solution is: the main screen of the grinding chamber of this machine is installed on the inner diameter of the circular iron plate 1 of the screen frame, and the screen frame 1 is located at the center point of 600 mm away from the vertical center line under the upper cover plate. The screen frame 1 is erected and installed on the working door 26 frame with 23 long screws and 22 long gaskets, which is also on the inner side of the upper iron plate on the front of the machine body. Another positive screen frame 1 is also erected and connected to the corresponding combined iron plate with 23 long screws and 22 long gaskets. On the plate 19, the combined iron plate is connected with several angle irons 20. After the center position is determined, the other end of the angle iron 20 is fixed on the iron plates on both sides of the body. Two large materials 9 are installed under the main screen of the crushing chamber, and the upper end is fixed to the inner side of the body by electric welding, and the lower end is tightly fixed to the wind-off feeder 12, so as to obtain a large surrounding space on the front. The side view is the same as the large combined space on the front, except that the isolation space for wrapping the circular mold body of the motor and the crushing chamber space need to be subtracted, and the rest is all the space for positive screening of powder. Compared with the more than 20 times space of the space channel for positive screening of powder in the prior art, the circular mold body 18 for wrapping the motor is installed on the combined iron plate on the right side of the crushing chamber and fixed with several screws, see Figures 2, 6 and 7 of the specification. In addition, if you want to increase the space, you can separate the upper cover plate to extend the space. If the extension exceeds the dust raising, you don't need to add the cover plate. The wind pressure in the large space will be smaller, which is beneficial to the higher 360° powder output rate of the main screen. The above claim 4 states that the machine body is cabinet-type and the technical solution of large powder outlet space is substantial and significant progress, describes the large space structure, and limits the scope of patent protection required by comparing with the entire content of the prior art.

5. The upgraded grinder is a medium-sized grinder for crushing corn feed. The technical solution for widening the grinding chamber: when the grinding chamber is widened by more than 200 mm, it is to use a variable-speed screw conveyor for center feeding. The screw conveyor is composed of a conveyor barrel and a spiral main shaft. The outstanding substantial feature and significant progress is that there are several discharge holes on the conveyor barrel. The purpose of several discharge holes is to ensure that the powder can evenly pass through the hammer bracket dividing blades 4 and reach the grinding chamber positive screen for crushing. Compared with the top feeding of the existing advanced technology water-drop hammer grinder, the center feeding of the screw conveyor can increase production by 35%. Because the water-drop grinder is top-fed, the U-shaped positive screen has 30% fewer positive screens, and the powder screen holes are covered by the raw materials that have just entered, which seriously reduces production by 35%. Installation method: See the attached figure of the specification for the schematic diagram of the working principle of the widened crushing chamber, Figure 3. The widening of the crushing chamber has increased, 31 reinforced several positive screens, which are installed at the lower part of the positive screen of the screen frame and are tightly combined. The two ends of the horizontal iron plate on the collar screen are fixed to the two ends of the positive screen frame, 33, the separation working door branch frame, which is made of angle iron frame, and there are 4 moving wheel devices at the bottom of the bracket. The upper part is connected to the working door with screws, which can be separated by removing the screws, 28, the screw conveyor is fixed on the circular bearing seat on the working door, 29, the circular bearing seat is fixed to the working door with screws, the bearing of the circular bearing seat is connected to the hollow support ring 38 of the hollow hammer frame, and the bearing seat of the separable bearing is installed on the hollow support frame at the other end. The backrest wheel is installed in the hollow support ring, and the backrest wheel is connected to the main shaft of the large motor. The large motor is upright and fixed on the combined iron plate. The combined iron plate is connected to several angle irons 20, which are respectively welded to the inside of the machine body after the center is aligned. 21 variable speed small motor is installed at one end of the propeller 28 feeding. The above claim 5, the outstanding substantial features and remarkable progress of the grinding chamber widening technical solution, describes the installation of all components and the entire contents of the relationship that the original grinder remains unchanged and only the grinding chamber is widened to produce a high-power grinder, which limits the scope of the patent protection required.

6. The upgraded mill is a medium-sized mill for crushing jade feed. Its substantial features and significant progress are as follows: the rotor internal resistance of the prior art mill is composed of a hammer bracket, a bracket main shaft, and a hammer. The main shaft is equipped with several circular sheet hammer brackets, each of which has several shaft holes. The hammer shaft holes are equipped with hammer shafts protruding from the planes on both sides of the circular bracket. A hammer is installed on each side of the shaft. This installation results in too many circular hammer brackets, which increases the weight. The distance from the hammer hole to the tail end is long. The number of hammers is too large, which increases the weight. Compared with the upgraded mill's grinding chamber widening technology, it is the same as the above prior art water drop mill, except that: (1) the hammer bracket is Without a main shaft, the weight can be reduced. (2) The grinding chamber is widened. The circular sheet bracket without widening the grinding chamber is hollow. There are several small planes protruding on the outer edge for installing the hammer shaft pin, which reduces the redundant edge planes and reduces the weight. The number of circular sheet brackets is reduced, which reduces the weight. (3) The circular sheet bracket itself has a large area of ​​solid, which can be hollowed out to reduce the weight. The upgraded hammer bracket and the material distribution blades and all the hammers of the crusher can reduce the weight by 1 / 3 compared with the existing crusher technology, achieving the goal of reducing the weight of the internal resistance by 1 / 3. Refer to the attached figure Figure 3 of the specification for the specific setting method of widening the hollow vertical sheet bracket in the grinding chamber to reduce the internal resistance and the connection relationship with other components, and make the following explanations: Hollow hammer bracket 4 It is composed of ① 4 material dividing blades; ② two hollow circular sheet brackets; ③ a reinforcing connecting plate is installed in the middle of the material dividing blade or a hollow hammer bracket is used to strengthen the middle reinforcing connection; ④ several hammers; ⑤ hammer long shaft pin; ⑥ support ring for supporting the weight of the widened hammer frame, hollow circular ring for supporting the bearing; ⑦ two circular bearing seats; ⑧ a pair of backrest wheels, a total of 8 items are installed, ① 4 material dividing blades are installed and connected to the corresponding inner side of the hollow circular bracket and fixed by electric welding; ⑦ bearing seats are respectively fixed on ⑥ hollow circular rings 38 supporting the bearing; ⑥ hollow circular rings are fixed on ④ hollow circular sheet hammer branch frames, and four small planes protrude on the outer diameter of the hollow circular sheet branch frame, and four holes are installed to connect the 4 hammer long shaft pins; ⑤ hammer When the long axle pin of the piece passes through the hollow bracket, four axle pins connect several hammer pieces ④, ⑥ A backrest wheel is installed on the left side of the hollow support ring 38 and then connected to 16 large motors. Compared with the existing water-drop type crusher of the same column shape, the different characteristics are:

1. The distance from the original hammer hole to the tail end is longer, which can be shortened to reduce weight; 2. The four small planes with holes protrude from the edge of the circular sheet hammer frame to reduce the excess weight on the edge, and there are many empty positions on the plane itself, which can reduce weight; 3. The number of hollow circular sheet hammer branches can be reduced, which can reduce weight.

4. There is no solid main shaft on the hammer bracket 4, which can reduce weight. The above four characteristics improve weight reduction, that is, reduce internal resistance and save power consumption. The description of the outstanding substantial features and remarkable progress of the technical solution for reducing internal resistance in claim 6 above, which reduces the support volume by 1 / 3 and the installation position relationship compared with the prior art, all defines the scope of the patent protection required.

7. The upgraded grinder is a medium-sized grinder for crushing corn feed. The machine body has a mobile technical solution, substantial characteristics and significant progress, which is characterized by The medium-sized pulverizer of modern technology can work normally only when it is connected with a suction fan and a large pipeline. It can only work in a fixed position and cannot move. Compared with the upgraded pulverizer, there is no suction fan and a large pipeline connected and fixed on the body. The body can work alone. There are 4 fixed hooks under the two sides of the body, like the moving wheels 17 of a rickshaw. The wheel axle is installed in the hook. The body can be moved to the raw material for production by pushing it, reducing the transportation cost of transporting a large amount of powder, see Figures 1 and 2. The above claim 7, the outstanding essential features and remarkable progress of the machine body moving technical solution compared with the prior art, describes that production can be moved to reduce transportation costs, and the entire content defines the scope of the patent protection required.

8. The upgraded grinder is a medium-sized grinder for crushing corn feed. The technical solution of adjustable separation and replacement of the blocking plate and the small hammer piece is an original technology. Its substantial characteristics and significant advancements are: ① The small concave arc screen piece and the positive screen piece are connected to form a 360° full screen and installed on the positive screen frame 1; ② Several long holes are prepared on the small arc screen piece, and the rectangular small hammer pieces with grooves pass through the long holes on the small concave arc screen to reach 3, the small hammer piece slide seat 25, and the slide seat 25 is fixed on both sides of the positive screen frame under the small concave arc screen; ③ The small hammer piece slot card is inserted into the small hammer piece slot, and there are two fixing holes on the small hammer piece card plate that are fixed in the screw holes on the slide slot. The small concave arc screen piece and the positive screen piece are connected as a whole or in sections. There are two installation methods. The sieve holes are of two types, circular or elongated. Several elongated holes slightly larger than the small hammer pieces are left in the middle of the small concave arc sieve piece. When the small hammer piece is installed, it can move in and out of the elongated holes. Several small hammer piece slide seats 25 are installed under several small arc sieve pieces. The separation card plate can repair the worn small hammer piece along the slide groove protrusion to the original position, or the whole old small hammer piece can be replaced with a new small hammer piece after withdrawing along the slide groove. The card plate is fixed in the side groove of the small hammer piece. The card plate has a fixing hole, and then the screw is dropped into the card plate hole and fixed in the threaded hole of the slide groove seat to form a joint body, and then it can continue to work. The first generation of small hammer pieces is vertically welded and fixed on the small concave arc sieve piece. Compared with the second generation adjustable separation replacement technology, the second generation replacement cost is dozens of times lower. See Figures 2 and 4. The above claim 8, the technical solution of the detachable and replaceable small hammer piece of the material blocking plate, the outstanding substantial characteristics and significant progress describe that the first-generation material blocking plate technology is compared with the second-generation material blocking plate technology, and the second-generation replacement cost is dozens of times lower, and the entire content of the composition, installation and relationship of each component limits the scope of the patent protection required.
