Description

TECHNICAL FIELD

[0001] The utility model relates to solid waste treatment and grinding technical field, especially a solid waste grinding material flow rate control partition warehouse board material cabin. BACKGROUND

[0002] In the field of solid waste treatment and grinding, the control of material flow rate is of great significance to improve grinding efficiency and product quality. In the process of solid waste grinding, the flow rate of material directly affects the distribution and residence time of material inside the mill, and then affects the grinding efficiency and the particle size distribution of the final product. If the material flow rate is too fast, the residence time of material in the mill will be reduced, resulting in insufficient grinding and affecting product quality; on the contrary, if the material flow rate is too slow, the residence time of material in the mill is too long, which not only reduces the grinding efficiency, but also may cause over-grinding of material, which also affects the product quality. Therefore, effective control of material flow rate is the key to improving grinding efficiency and ensuring product quality. Although the traditional solid waste grinding system can complete the grinding task well, the traditional solid waste grinding system often has the problem of difficult accurate control of material flow rate, which not only affects the grinding efficiency, but also may cause unstable product quality.

[0003] In the existing technology, the design and application of partition warehouse board is the key to control the flow rate of material. The partition warehouse board divides the mill cylinder into multiple compartments to adapt to the grinding of materials of different particle sizes and control the flow rate of material in the mill. However, once the traditional partition warehouse board is put into operation, the throughput and flow rate of material in the mill cannot be controlled and adjusted, and the grinding capacity of each compartment cannot be effectively balanced, so that the mill is in the best operating condition. In addition, the partition warehouse board control is a new control method that has appeared in recent years, but the partition warehouse board has too small throughput, and relies too much on the pressure of the front and rear materials, so the amount of material from coarse material to fine material cannot be controlled, and some other methods need to be used to push the material. The traditional material size distribution can only rely on the grate type opening of the partition warehouse board, and lacks the initiative of monitoring.

[0004] Therefore, in order to improve the grinding efficiency of solid waste grinding material, it is urgent to develop a high-efficiency and controllable solid waste grinding material flow rate control partition warehouse board material cabin. SUMMARY

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Embodiment one

[0032] As shown in Figure 1 and Figure 5 , a construction waste recycled aggregate air compression system, the operation method thereof comprises the following steps:

[0033] S1, starting the powder grinding cabin;

[0034] S2, adding materials;

[0035] S3, grinding the coarse materials in the cabin;

[0036] S4, passing through the middle partition plate;

[0037] S5, fine material cabin grinding;

[0038] S6, passing through the tail partition plate;

[0039] S7, checking the quality of the powder;

[0040] S8, grinding is finished.

[0041] As shown in Figure 1 and Figure 2 , the barrel 6 is provided with a material cabin 15, the outer side of the barrel 6 is provided with a motor 1 and a speed reducer 3, the motor 1 is connected with the input shaft of the speed reducer 3, the output shaft of the speed reducer 3 is connected with a pinion 4, the outer side of the barrel 6 is provided with a gear 5, the pinion 4 is engaged with the gear 5. After the power is turned on, the motor 1 will start, the rotation of the motor 1 is transmitted to the speed reducer 3 through the transmission shaft 2 connected between the speed reducer 3 and the motor 1, the speed reducer 3 will reduce the high speed transmitted by the motor 1 and increase the torque, and then the transmission shaft 2 transmits to the pinion 4 at the other end, the pinion 4 rotates and drives the gear 5 fixed outside the barrel 6, the gear 5 is engaged with the pinion 4, the rotation of the pinion 4 drives the rotation of the gear 5, and finally the rotation of the motor 1 is transmitted to the barrel 6.

[0042] Before starting the material cabin 15, the whole structure of the material cabin 15 needs to be checked to confirm whether the connection between each component is good and reliable, whether the connection part is loose, to ensure that each part can work normally, and to ensure that the motor 1 has no short circuit. After starting the grinding material cabin 15, attention should be paid to its normal working state under no load before entering the load operation.

[0043] As shown in Figure 2 , one end of the barrel 6 is provided with a feeding channel 8, the upper side of the feeding channel 8 is provided with a chute 10, and the upper end of the chute 10 is provided with a hopper 7. After confirming that the whole machine can work normally, the material to be ground is poured into the hopper 7, and the material slides into the feeding channel 8 below through the chute 10 below the hopper 7. The feeding channel 8 contains a channel spiral device 11, which is composed of a middle rotating rod 13 and a plurality of steel spiral blades 12 fixed on the rotating rod 13. One end of the rotating rod 13 is connected with a driving device 14, which drives the rotation of the channel spiral device 11 through the driving device 14 at one end. The driving device 14 can receive signals from the terminal and control the speed of the channel spiral device 11 through the signals, so as to control the speed of the material entering the coarse material cabin 16 inside the barrel 6.

[0044] As shown in Figure 2As shown, the configuration of the spiral blade 12 needs to be arranged to the end of the feed channel 8 where it connects with the coarse material cabin 16, the purpose of which is to prevent the backflow of large steel balls 17 during grinding. And the drive device 14 of the channel spiral device 11 needs to be isolated from the feed channel 8, in order to prevent small fragments and dust of solid waste from interfering with the work of the drive device 14, and ultimately causing the feed channel 8 to lose its feeding effect. In this embodiment, the drive device 14 is selected as a speed reducer motor.

[0045] As shown in the drawings, Figure 2 The material cabin 15 is provided with a middle partition plate 21, and the material cabin 15 is divided into a coarse material cabin 16 and a fine material cabin 18 by the middle partition plate 21. The coarse material cabin 16 is provided with large steel balls 17 as grinding bodies, which are used to grind untreated aggregates. The fine material cabin 18 contains small steel balls 19 as grinding bodies, which are used to grind aggregates that have been preliminarily processed by the large steel balls 17 in the coarse material cabin 16. The method of grading and grinding aggregates is used to adapt to the reasonable principle of using large steel balls 17 for coarse aggregates and small steel balls 19 for fine particles in the material grinding process, thereby fully exerting the grinding capacity of the grinding bodies.

[0046] As shown in the drawings, Figure 2 The material enters the material cabin 15 through the feed channel 8. The material cabin 15 is in the cylinder body 6, and the cylinder body 6 and the material cabin 15 are integrated. An acoustic insulation material 20 is provided between the cylinder body 6 and the material cabin 15, the purpose of which is to prevent excessive noise caused by the mutual impact of the grinding bodies during operation. The inner side of the acoustic insulation material 20 is provided with a lining plate 22, and the material cabin 15 is wrapped by the lining plate 22. The lining plate 22 plays a protective role for the cylinder body 6, preventing the cylinder body 6 from being directly impacted and ground by the grinding bodies (large steel balls 17 and small steel balls 19) and the material, thereby prolonging the service life of the cylinder body 6 and the entire equipment. At the same time, the lining plate 22 and the cylinder body 6 are tightly combined together, which also plays a role in enhancing the stiffness of the cylinder body 6. The grinding bodies in the coarse material cabin 16 are large steel balls 17, the number of which should account for 30% to 50% of the volume of the cylinder body. The large steel balls 17 move with the rotation of the cylinder body 6, and are lifted to a certain height under the action of centrifugal force and friction, and then fall freely under the action of gravity, impacting and grinding the material.

[0047] As shown in the drawings, Figure 2As shown, the first intracabin spiral device 23 is also in the coarse material cabin 16, which is composed of a main rod 24 and intracabin spiral blades 25. The main rod 24 is connected with the middle partition plate 21 by welding, and is installed in the middle of the middle partition plate 21. The intracabin spiral blades 25 are evenly distributed on both sides of the main rod 24. The middle partition plate 21 and the cylinder 6 are connected by bolts 9. When the cylinder 6 starts to rotate, the middle partition plate 21 rotates with the cylinder 6, and the rotation of the middle partition plate 21 drives the rotation of the main rod 24 and the intracabin spiral blades 25, thereby pushing the intracabin material to flow to the next cabin. In addition, due to the existence of the intracabin spiral blades 25, the aggregate can be lifted, the contact volume of the aggregate and the large steel balls 17 in the coarse material cabin 16 is increased, and the grinding speed of the aggregate is accelerated.

[0048] As shown in the drawings, Figure 2 During the rotation of the cylinder 6, the abrasive bodies are lifted to a certain height by the friction force of the surface of the liner plate 22, and are given a certain potential energy and a falling kinetic energy, so that the large steel balls 17 produce a "circular arc-parabolic" motion trajectory meeting the requirements of the grinding process, and impact and grind the material.

[0049] The large steel balls 17 will be continuously worn during grinding and need to be replaced regularly to maintain the grinding efficiency. The maximum wear rate of the steel balls is about 0.3 kg / Mg for very abrasive materials, about 1-1.5 kg / Mg for dry grinding, and about 1-1.5 kg / Mg for wet grinding.

[0050] The liner plate 22 can adopt an angular spiral liner plate, a conical surface grading liner plate, etc. The abrasive bodies of different gradings in the material cabin 15 can be reasonably graded in the axial direction of the material cabin 15 according to the change of the grinding particle size, so that the steel balls of various diameters can play the maximum function in the process of crushing the material of corresponding particle size.

[0051] As shown in the drawings, Figure 2 After the material is ground in the coarse material cabin 16, it will come to the side of the middle partition plate 21 close to the coarse material cabin 16 under the driving of the first intracabin spiral device 23. The first intracabin spiral device 23 is installed with a first material lifting plate 26 on the main rod 24. One side of the first material lifting plate 26 is close to the middle partition plate 21, and the first material lifting plate 26 will lift the ground aggregate in the coarse material cabin 16 due to the rotation of the middle partition plate 21, so that the aggregate is evenly and quickly distributed in the vertical plane of the middle partition plate.

[0052] As shown in the drawings, Figure 3As shown, the middle partition plate 21 is provided with arc grate holes 27, which are uniformly distributed on the middle partition plate 21. The size of the arc grate holes 27 is controlled to control the size of the aggregate allowed to pass. The aggregate that is too coarse cannot pass through the arc grate holes 27 on the middle partition plate 21 and is blocked by the arc grate holes 27 to stay in the coarse material cabin 16 for further grinding by the large steel balls 17, while the aggregate that reaches the required fineness can pass through the middle partition plate 21 to enter the fine material cabin 18.

[0053] As shown in Figure 3 and Figure 2 , one side of the first lifting plate 26 is close to the middle partition plate 21 and rotates due to the rotation of the first cabin internal screw device 23. The first lifting plate 26 forms an angle with the middle partition plate 21 and is inclined relative to the middle partition plate 21. The inclination direction of the first lifting plate 26 relative to the middle partition plate 21 is consistent with the rotation direction of the first lifting plate 26. This facilitates the collection and lifting of the aggregate and ensures that the aggregate will not be spilled due to other vibrations during the lifting process, thereby reducing the passing efficiency of the aggregate. In addition, the inclination of the first lifting plate 26 gives the aggregate a force towards the fine material cabin 18, which facilitates the passing of the aggregate through the middle partition plate 21. Furthermore, due to the cooperation of the first lifting plate 26 and the arc grate holes 27, the aggregate that meets the fineness requirement is transported to the fine material cabin 18, while the aggregate that does not meet the fineness requirement is left in the coarse material cabin 16 for further grinding. Finally, the first lifting plate 26, like the first cabin internal screw device 23, increases the contact volume of the aggregate and the large steel balls 17 by lifting the aggregate, thereby increasing the grinding speed.

[0054] As shown in Figure 3 and Figure 2 , the middle partition plate 21 blocks the larger particles of material in the coarse material cabin 16 through its arc grate holes 27, so that they continue to be ground and crushed, preventing the passage of oversized particles into an area with weaker impact force and thereby avoiding the problem of slow grinding efficiency. At the same time, the middle partition plate 21 reduces the possibility of backflow of the aggregate fluid, improves the working efficiency of the material cabin 15, and also avoids the accumulation of uncrushable material blocks, which seriously affects the grinding effect.

[0055] Since the arc grate holes 27 of the middle partition plate 21 may inevitably have the situation that the size is just right to pass but is stuck, a vibration device 28 can be installed in the main rod 24 of the first cabin internal screw device 23. The vibration device 28 can generate vibrations that are transmitted to the middle partition plate 21, thereby shaking the aggregate stuck in the arc grate holes of the middle partition plate 21. Since the aggregate is just stuck in the holes, it does not matter whether the aggregate falls into the coarse material cabin or the fine material cabin.

[0056] As shown in Figure 2As shown, the aggregate comes to the fine material cabin 18 for grinding after passing through the middle partition plate 21, and the grinding body in the fine material cabin 18 is a small steel ball 19, the number of the small steel ball 19 accounts for 30% to 50% of the volume of the cylinder 6, the small steel ball 19 is lifted to a certain height under the action of centrifugal force and friction, and then freely falls due to gravity to impact and grind the fine aggregate. The fine material cabin 18 is provided with a second in-cabin spiral device 43, which is composed of a main rod 24 and in-cabin spiral blades 25, the main rod 24 is connected together with the middle partition plate by welding, the main rod 24 is installed at the middle position of the tail partition plate 29 and the middle partition plate 21, the in-cabin spiral blades 25 are uniformly distributed on both sides of the main rod, and the tail partition plate 29 is connected together with the cylinder 6 by bolts 9, the tail partition plate 29 is located at the end of the cylinder 6 away from the feeding channel 8. When the cylinder starts to rotate, the tail partition plate 29 rotates together with the cylinder 6, drives the main rod 24 in the fine material cabin 18 to rotate and in turn drives the in-cabin spiral blades 25 on the main rod 24 to rotate, the rotation of the in-cabin spiral blades 25 pushes the material in the fine material cabin 18 to flow to the discharge cabin 30; in addition, thanks to the existence of the spiral blades 25, the aggregate can be lifted, the contact volume of the aggregate and the small steel balls 19 in the fine material cabin is increased, and the grinding speed of the aggregate is accelerated.

[0057] As shown in Figure 2 and Figure 3 shown, the tail partition plate 29 is provided with a second material lifting plate 42, the second material lifting plate 42 is installed on the main rod 24 of the second in-cabin spiral device 43 in the fine material cabin 18, and the second material lifting plate 42 will lift the ground aggregate in the fine material cabin 18 due to the rotation of the middle partition plate 21 and the tail partition plate 29, so that the aggregate is evenly and quickly distributed in the vertical plane of the middle partition plate 21. The tail partition plate 29 is provided with arc grate holes 27, the arc grate holes 27 are uniformly distributed on the tail partition plate 29, and the distribution density of the arc grate holes 27 on the tail partition plate 29 is more dense than that of the arc grate holes 27 on the middle partition plate 29, and the size of the aperture of the arc grate holes 27 on the tail partition plate 29 meets the diameter requirement of the final required powder. The arc grate holes 27 control the size of the powder allowed to pass by controlling the size of the aperture, and the coarse powder cannot pass through the tail partition plate 29, and is blocked by the arc grate holes 27 on the tail partition plate 29 to stay in the fine material cabin 18 for further grinding by the small steel balls 19, and the aggregate meeting the fineness requirement will pass through the tail partition plate to enter the discharge cabin.

[0058] One side of the second lifting plate 42 is close to the tail partition plate 29 and rotates with the rotation of the second inner screw 43. The second lifting plate 42 and the tail partition plate 29 form a certain angle and are inclined to the tail partition plate 29. The inclined direction of the second lifting plate 42 to the tail partition plate 29 is consistent with the rotation direction of the second lifting plate 42. This facilitates the collection and lifting of the powder and ensures that the powder will not be spilled due to other vibrations during the lifting process, thereby reducing the passing efficiency of the powder. In addition, due to the inclination of the second lifting plate 42, the aggregate on the second lifting plate 42 will be given a force towards the discharge cabin 30, which facilitates the passing of the aggregate through the tail partition plate 29. In addition, due to the cooperation of the second lifting plate 26 and the arc grate-shaped hole 27 on the tail partition plate 29, the aggregate meeting the fineness requirement will be transferred to the discharge cabin 30, and those not meeting the fineness requirement will be left in the fine powder cabin 18 for further grinding. In addition, the second lifting plate 42 and the second inner screw 43 in the fine powder cabin 18 increase the contact volume of the aggregate and the small steel balls 19 by lifting the aggregate.

[0059] As Figure 2 shown, due to the diameter of the powder after grinding in the fine powder cabin 18 is too fine, it will occasionally accumulate in the arc grate-shaped hole 27 of the tail partition plate 29, thereby causing the blockage of the tail partition plate 29, which will greatly affect the working efficiency of the cabin. Therefore, a vibration device 28 is installed in the main rod 24 of the second inner screw 43 in the fine powder cabin 18. The vibration device 28 can generate vibrations, which will be transmitted to the tail partition plate 29, thereby shaking off the powder accumulated in the arc grate-shaped hole of the tail partition plate 29.

[0060] As Figure 2 and Figure 4As shown, the powder material in the fine material cabin 18 is driven by the second material lifting plate 26 and the second cabin internal screw device 43 to pass through the tail partition plate 29 into the discharge cabin 30. The discharge cabin 30 is arranged at the end of the cylinder 6 away from the feeding channel 8; the discharge cabin 30 is provided with a weighing device 31, and the weighing device 31 is provided with a weighing platform 32, which is located below the tail partition plate 29; the weighing device 31 can weigh the powder material coming out of the tail partition plate 29 on the weighing platform 32 to obtain the weight of the powder material produced in a period of time, and the weight obtained will be uploaded to the Internet of Things terminal by the weighing device 31, and the weight will be judged by the computer and assisted by the computer vision technology to control the motor 1 and the driving device 14 of the channel screw device 11, thereby controlling the speed of the produced powder material. However, only the control of the speed is not enough, so the gradation of the powder material also needs to be controlled. The top of the discharge cabin 30 is provided with a camera 33 for computer vision recognition, and the camera 33 is provided with a dustproof and anti-static glass 34. The camera 33 is covered by the dustproof and anti-static glass 34, and the camera 33 and the internal space of the discharge cabin 30 are isolated by the dustproof and anti-static glass 34. The dustproof and anti-static glass 34 can keep the camera 33 clear at all times, and the discharge condition of the discharge cabin 30 is observed through the camera 33; the state of the powder material on the weighing platform 32 is observed, and the collected image is transmitted to the data terminal; the camera 33 is installed in the monitoring space on the top of the discharge cabin 30 through a support 35, and the monitoring space is isolated by the dustproof and anti-static glass 34. When the dustproof and anti-static glass 34 is spliced, high-strength glue is used to ensure the air tightness and prevent the dust of the crushed material from entering. In order to ensure the recognition brightness of the camera, the lighting can be installed in the discharge cabin, or the night vision camera can be used.

[0061] As Figure 1 , Figure 4 , Figure 6When the output of the powder is less than the set output per unit time, the terminal sends a signal to increase the speed of the motor 1, thereby increasing the speed of the cylinder 6, and ultimately speeding up the movement of the first cabin screw device 23, the second cabin screw device 43, and the large steel ball 17 and the small steel ball 19 in the cabin, increasing the grinding speed and the feeding speed. However, it is not enough to have a fast grinding speed. The terminal also sends a signal to the driving device 14 of the channel screw device 11. When the driving device 14 and the cylinder 6 increase in speed, the powder production speed can be increased. When the powder production rate is much higher than the set fixed value, the powder production rate needs to be reduced. The terminal sends a signal to reduce the speed of the motor 1 and the driving device 14 of the channel screw device 11. When the powder is weighed, the camera 33 in the upper monitoring space identifies the powder on the weighing platform 32. The identified content is the particle fineness of the powder per unit time. Although the powder is screened by the tail partition plate 29, there is an error in the size of the partition plate aperture during production, and there may also be slight deformation, which may cause particles with a diameter slightly larger than the required powder to appear. Therefore, further detection is needed. In addition, there may be fine powder. Fine powder may cause other problems in subsequent use, so fine powder also needs to be monitored. Before production, the powder diameter needs to be set in advance. During production, the terminal analyzes the data uploaded by the camera 33 and controls the motor 1 and the driving device 14 of the channel screw device 11 according to the diameter. When the camera 33 identifies too much powder with a particle size larger than the set particle size, the terminal slightly reduces the speed of the motor 1, thereby increasing the grinding time of the aggregate in the cabin and reducing the particle size of the powder. When the identified particle size is too small, the speed can be gradually increased to increase the output and reduce the grinding time of the aggregate in the cabin 15. Until the output particle size is close to the set particle size, a certain deviation can be allowed.

[0062] As Figure 6As shown, in the step of checking the quality of the powder, the quality G0 of the powder and the diameter D0 of the powder required in a unit of time need to be set in advance according to the use of the product and the specification. According to the two parameters, the Internet of Things terminal makes a judgment on the quality G and the diameter D of the powder produced in a unit of time uploaded by the weighing device 31 and the camera 33. When making the judgment, there should be an allowed deviation Δ, and the value of the deviation Δ is determined according to the use specification. When the weight G is greater than G0±Δ and the diameter D is greater than D0±Δ, the speed of the motor 1 and the driving device 14 needs to be reduced. When the weight G is less than G0±Δ and the diameter D is less than D0±Δ, the speed of the motor 1 and the driving device 14 needs to be reduced. When the weight G is greater than G0±Δ and the diameter D is less than D0±Δ, the computer will continuously adjust the speed. Since the motor 1 and the driving device 14 are controlled separately, a set of appropriate motor speed and driving device speed can be found to make D and G approach D0 and G0, and vice versa.

[0063] Whether it is weight detection or particle size detection, the terminal detection should not be too harsh, and a floating value within the specification and error should be designed to reduce the terminal calculation burden and avoid a series of problems that may occur due to the frequent calling of the motor 1 and the driving device 14.

[0064] As shown, Figure 4 When the powder is detected on the weighing platform 32, the weighing platform 32 has an appropriate inclination angle, and the inclination angle is designed to be 2°-3°. The surface of the weighing platform 32 cannot be too smooth to ensure that the powder falling on the weighing platform 32 will not slide off, so as to ensure that the weighing device 31 installed under the weighing platform 32 can weigh the collected powder, and the computer vision camera 33 has enough time to identify the granularity of the powder. At the same time, the weighing device 31 is also provided with an auxiliary vibration device 36, which makes small vibrations to the weighing platform 32. The vibration can make the aggregate on the weighing platform 32 spread evenly, avoid the deviation of the center of gravity caused by the aggregate piling up, and finally cause the weighing error, which affects the judgment of the computer terminal. Moreover, under the action of the auxiliary vibration device 36, the longitudinal wave generated by the auxiliary vibration device 36 can make the powder with larger particles float to the surface of the powder, so that the computer vision camera can identify the diameter distribution of the particles more quickly.

[0065] As shown, Figure 4As shown, the vibration of the auxiliary vibration device 36 also helps the powder flow slowly down the slope 37 after being monitored, the slope 37 is installed with the weighing platform 32, the upper end of the slope 37 is connected with the lower end of the weighing platform 32 through the damping rubber strip 38, and the lower end of the slope 37 is provided with a discharging vibration device 39, the vibration frequency of which is higher than that of the auxiliary vibration device 36, which is to accelerate the discharging. The qualified powder can be directly discharged from the discharge port 40 at the lower end of the discharge cabin 30 for bagging, packaging and use. The discharging vibration device 39 can avoid the accumulation of powder on the slope 37, which reduces the delivery rate. The slope of the slope 37 can be designed to be larger, while ensuring smoothness, so as to avoid the accumulation of powder. Because the vibration frequency of the discharging vibration device 39 is much higher than that of the auxiliary vibration device 36, the vibration of the discharging vibration device 39 will affect the powder on the weighing platform 32 to slide onto the slope 37 too early and discharge too early, thereby affecting the acquisition of parameters in the step of checking the quality of the powder, so the damping rubber strip 38 needs to be added between the slope 47 and the weighing platform 32 to avoid the mutual influence.

[0066] As shown in Figure 2 In order to solve the problem of heat accumulation in the powder processing process in the material cabin 15 and the problem of powder accumulation due to static electricity, a water spraying device 41 can be added in the material cabin 15 to solve the above problems. The water spraying in the material cabin 15 can directly act on the material and grinding body in the grinding process, quickly absorb heat and convert it into water vapor, thereby taking away a large amount of heat energy; in actual production, appropriate water spraying amount can ensure normal operation and cooling effect of the device.

[0067] Before starting the material cabin 15, check whether each part is intact, ensure that all fasteners are tightened, and confirm whether the lubricating oil is sufficient and replace it in time. Clean the outside of the material cabin regularly, clean the surface dust, dirt and sundries, prevent these substances from entering the equipment and affecting the operation. Especially the feeding hopper 7 and the discharge port 40 around, keep clean, avoid material accumulation affecting normal feeding and discharging. Regularly check the electrical system, including motor 1, reducer 3, wire cable, etc. Check the running state of the motor, such as current, voltage, temperature, etc. When large batch of pulp is produced, do not add all powder and adhesive together for mixing, so as to avoid hard mass.

[0068] Regularly check and maintain the material cabin 15 to ensure that the equipment is in good condition. Clean the material and steel balls in the material cabin 15 to avoid deformation and bending of the cylinder 6 caused by long-term shutdown. The operator must be professionally trained, familiar with the structure, performance and operation procedures of the material cabin 15, and wear personal protective equipment.

[0069] If there are abnormal conditions such as loud noise and strong vibration during the operation of the material bin 15, the machine is stopped in time to repair the reducer 3, the motor 1 and other equipment.

[0070] The circular arc grate-shaped hole 27 of the tail partition plate 29 needs to be smaller in diameter than the circular arc grate-shaped hole 27 of the middle partition plate 21.
