Description

Technical Field

[0001] The invention relates to the technical field of material processing, in particular to an improved roller press extrusion system. Background Art

[0002] Roller press is a kind of high-efficiency grinding equipment widely used in mining, cement, metallurgy and other industries. It is mainly used for pre-crushing or fine crushing of various hard materials. Its working principle is to apply huge squeezing force to the material through two relatively rotating high-pressure rollers, so that the material is crushed or refined when passing through the gap between the two rollers. The core of the roller press system is to provide stable and efficient material supply and processing capabilities to ensure the continuity of the production process and product quality.

[0003] In traditional roller press systems, a steady flow weighing bin is often configured above the roller press, and its main purpose is to provide stable and uniform material pressure and material supply for the roller press. However, there are many outstanding problems in the steady flow weighing bin above the roller press that have not been solved. For example, in order to ensure that the material in the bin does not accumulate and maintain a stable material pressure, it is usually necessary to increase the cone angle at the bottom of the bin, which will lead to a further increase in the bin height, thereby increasing the height requirements of the plant and conveying equipment. In addition, since the bottom of the steady flow weighing bin is conical and has a relatively large volume, the material in the bin is prone to segregation, which may not only cause the roller press to deviate, reduce the work efficiency and extrusion effect, but also cause the material to collapse or rush, causing impact on subsequent equipment. In addition, due to the existence of the bin, dust points are increased, which worsens the working environment of the workshop. Therefore, an improved roller press extrusion system is proposed. Summary of the invention

[0004] The object of the present invention is to provide an improved roller press extrusion system to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an improved roller press extrusion system, comprising a sorter and a roller press, wherein the sorter is connected to the roller press through a chute to complete the material transportation, the chute is located above the roller press and is provided with an overflow port, the chute is located at the position of the overflow port and is provided with a discharge pipe, the end of the discharge pipe is connected to a slag discharge bin, wherein the combination of the chute, the overflow port, the discharge pipe and the slag discharge bin replaces the steady flow weighing bin used to stabilize the material pressure in the traditional roller press system, and the bottom of the slag discharge bin is provided with a speed regulating conveyor.

[0006] As a further solution of the present invention: a first manual rod valve and a pneumatic rod valve are installed on the slide pipe, and the first manual rod valve and the pneumatic rod valve are both located below the overflow port.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present application adds an overflow port to the chute and connects a discharge pipe connected to the slag discharge bin at the overflow port. The combination of the chute, overflow port, discharge pipe and slag discharge bin replaces the steady flow weighing bin used to stabilize the material pressure in the traditional roller press system.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-3In the embodiment of the present invention, an improved roller press extrusion system includes a sorter 1 and a roller press 2. The sorter 1 is connected to the roller press 2 through a chute 3 to complete the material transportation. The chute 3 adopts a pipeline design, which is different from the conical cylinder structure of the steady flow weighing bin. The existence of the steady flow weighing bin is easy to cause the material to segregate in the bin, that is, the separation of materials with different particle sizes or densities. The material segregation may not only cause the roller of the roller press to deviate, reduce its work efficiency and extrusion effect, but also cause uneven distribution of materials in the bin. This situation will cause unnecessary impact on subsequent equipment and affect the stability and safety of the entire production line. In contrast, the pipeline design of the chute 3 The design effectively avoids the above problems, ensures the uniformity and continuity of the material transmission process, reduces the risk of impact on subsequent equipment, and thus improves the stability and working efficiency of the entire system; the chute 3 is provided with an overflow port 4 above the roller press 2. Because the height of the overflow port 4 on the chute 3 is fixed, the material pressure of the material entering the roller press 2 is stable and the material column is dense, which can meet the working premise of the supersaturated feeding and steady flow material pressure of the roller press 2, so that the material segregation is less, and the roller press 2 runs stably. The chute 3 is provided with a discharge pipe 5 at the position of the overflow port 4, and the end of the discharge pipe 5 is connected to the slag discharge bin 6, wherein the chute 3, the overflow port 4, the discharge pipe 5 and The combination of the slag discharge bin 6 replaces the steady flow weighing bin used to stabilize the material pressure in the traditional roller press system. When the material in the chute 3 is higher than the overflow port 4, it will enter the slag discharge bin 6 through the overflow port 4 and the discharge pipe 5 in sequence. The design and layout of the chute 3 are flexible and can be adjusted according to the specific warehouse conditions to ensure that its installation will not affect the height space inside the factory building. Compared with the steady flow weighing bin, the chute 3 has a more compact and small structure, which is easy to install and arrange and adapt to different on-site environments. The chute 3 adopts a fully enclosed design with only necessary entrances and exits, which effectively reduces the dust problem in the material handling process. Due to the reduction of dust points, the chute 3 has It helps to maintain the cleanliness of the work site and provide a better working environment. A speed-regulating conveyor 7 is provided at the bottom of the slag discharge bin 6, and the chute 3 is designed in a pipeline shape, and there is no design of a steady-flow weighing bin. The design of a steady-flow weighing bin can easily lead to segregation of materials in the bin, which can easily cause the roller press to be biased, with low work and poor extrusion effect. Segregation of materials in the bin can easily cause bin collapse and material rushing, which will have an impact on subsequent equipment. In addition, the existence of the slag discharge bin 6 can store the return material of the system under abnormal working conditions. In addition, as the eyes of the material balance of the roller press system, changes in the bin position will reflect whether the material of the roller press system is balanced, thereby facilitating the central control operator to adjust the system parameters.

[0023] See also Figure 1In one embodiment, in this embodiment, preferably, a first manual rod valve 8 and a pneumatic rod valve 9 are installed on the chute 3, and the first manual rod valve 8 and the pneumatic rod valve 9 are both located below the overflow port 4. A load sensor 11 is installed in the slag discharge bin 6. A second manual rod valve 10 is set between the slag discharge bin 6 and the speed regulating conveyor 7 to control whether the material inside the slag discharge bin 6 is discharged. During normal production, the first manual rod valve 8, the pneumatic rod valve 9 and the second manual rod valve 10 are all in an open state. When the amount of material transported exceeds the position of the overflow port 4 on the chute 3, it will flow into the slag discharge bin 6 through the discharge pipe 5, and the load sensor 11 located in the slag discharge bin 6 The sensor 11 monitors the changes in the storage position of the materials in the bin in real time. Since the speed-adjusting conveyor 7 is in a state of constant speed operation, the feeding and discharging of the entire extrusion system are balanced at this time. When the load sensor 11 detects an abnormal change in the storage position, it means that the balance between the feeding and discharging of the system is broken. At this time, the operator will adjust the system parameters or adjust the conveying speed of the speed-adjusting conveyor 7 to re-establish the balance. When the system is under maintenance or started and stopped, the operator will close the pneumatic rod valve 9 and the second manual rod valve 10. In order to prevent the pneumatic rod valve 9 from having an abnormality, a first manual rod valve 8 is also provided for manual closing.

[0024] See also Figure 1 In one embodiment, in this embodiment, preferably, the sorting machine 1 includes a first outlet 1-1, which is connected to the roller press 2 through a chute 3, and the material discharged through the first outlet 1-1 is a coarse material that needs to be reprocessed by the roller press 2 to become a fine material; the second outlet 1-2, which is directly connected to the next process, and the material discharged through the second outlet 1-2 is a fine material that can directly enter the next process for processing.

[0025] See also Figure 2 In one embodiment, in this embodiment, preferably, the speed-regulating conveyor 7 includes a bracket 7-1 and a belt 7-3 arranged on the bracket 7-1 and driven by a motor 7-2 for operation. When the motor 7-2 rotates forward, the belt 7-3 on the speed-regulating conveyor 7 runs toward one side to send the material discharged from the slag bin 6 into the interior of the sorting machine 1 for secondary sorting. When it is necessary to clean the impurities in the chute 3, the motor 7-2 will be set to a reverse mode. At this time, the belt 7-3 on the speed-regulating conveyor 7 will run in the opposite direction. This reverse movement ensures that the impurities discharged from the slag bin 6 can be effectively transmitted outward instead of entering the normal material processing process. When the belt 7-3 moves toward the other side, any impurities falling on the belt 7-3 will not enter the collecting pipe 13, away from the normal material flow, so that the staff can more conveniently collect and process these impurities in a unified manner. In addition, by adjusting the speed of the motor 7-2, the material conveying speed can be adjusted to achieve a balance between feeding and discharging.

[0026] See also Figure 1 In one embodiment, in this embodiment, preferably, the roller press 2 is provided with a discharge channel 12 for discharging the processed material from the roller press 2, and the end of the discharge channel 12 is connected to the next process.

[0027] See also Figure 1 In one embodiment, in this embodiment, preferably, it also includes a collecting pipe 13 and a feeding pipe 14. The collecting pipe 13 has three interfaces, one of which is connected to the speed-regulating conveyor 7 to receive the material discharged through the slag discharge bin 6, another interface is the raw material inlet, and the remaining interface is connected to the end of the feeding pipe 14. The other end of the feeding pipe 14 is connected to the sorting machine 1. Further, it is convenient to gather the speed-regulating conveyor 7 and the raw materials and then send them back into the sorting machine 1 through the feeding pipe 14.

[0028] The working principle and use process of the present invention are as follows: the raw materials are first fed into an interface of the collecting pipe 13, and then these materials are transmitted to the interior of the sorting machine 1 through the feeding pipe 14. In the sorting machine 1, the materials are divided into fine materials and coarse materials according to the particle size, wherein the fine materials are discharged through the second outlet 1-2 and enter the next process, and the coarse materials enter the chute 3 through the first outlet 1-1, ready for further processing, and the coarse materials are sent to the roller press 2 through the chute 3 for extrusion processing, and the processed materials are discharged from the system through the discharge channel 12. Due to the working characteristics of the roller press oversaturated feeding, when the material fills the chute 3, the excess material will reach the overflow port 4, and the excess material will be automatically introduced into the slag bin 6 through the discharge pipe 5 and transported to the speed-adjustable conveyor 7. The speed-adjustable conveyor 7 returns the material in the slag bin 6 to the roller press 2 to realize the recycling and reprocessing of the material.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
