Description

Technical Field

[0001] This application relates to the technical field of large sugarcane presses, and particularly to an anti-blocking device for the lotus root tube holes of the rear roller of a press. Background Art

[0002] The three-roller press is a commonly used sugarcane pressing device in current sugar manufacturing enterprises. There are a total of three large pressing rollers in the three-roller press, which are arranged in a triangular formation and installed on the press. The top pressing roller is the top roller, and the two lower pressing rollers are the front roller and the rear roller. When the press is working, through the cooperation of the three rollers, pressure is applied to the sugarcane filaments, so that the cane juice is squeezed out. After subsequent concentration, crystallization and other treatments, the common white granulated sugar can be obtained. In order to improve the pressing efficiency, sugar factories usually use multiple presses to continuously press the sugarcane filaments. After being pressed in the press, the sugarcane filaments are discharged from the rear roller. The sugarcane filaments in the last press become very fragmented after being rolled by the previous presses, and the water content of the sugarcane in the last press is also relatively low, resulting in the bagasse being easy to block the lotus root tube holes of the rear roller, affecting the discharge of the water content of the bagasse, making the water content of the bagasse too high and affecting the fuel efficiency of the boiler. Therefore, an anti-blocking device for the lotus root tube holes of the rear roller of a press is needed. A spray head is installed on the bearing seat on one side of the rear roller, which can inject water flow into the lotus root tube holes to flush out the bagasse in the lotus root tube holes and prevent the lotus root tube holes from being blocked, which is of great significance for reducing the water content of the bagasse. Summary of the Utility Model

[0003] In order to solve the above problems, this application proposes an anti-blocking device for the lotus root tube holes of the rear roller of a press. A spray head is installed on the bearing seat on one side of the rear roller, which can inject water flow into the lotus root tube holes to flush out the bagasse in the lotus root tube holes and prevent the lotus root tube holes from being blocked, which is of great significance for reducing the water content of the bagasse.

[0004] This application is achieved through the following technical solutions:

[0005] This application proposes an anti-blocking device for the lotus root tube holes of the rear roller of a press, including: a rear roller bearing seat, a rear roller, a spray head, and a high-pressure water tank. The rear roller is provided with lotus root tube holes, and both ends of the rear roller are installed on the frame through the rear roller bearing seat; the spray head is connected to the bottom of the high-pressure water tank through a water outlet pipe, and the spray head is installed on the rear roller bearing seat through a first bracket. The spray head faces the lotus root tube holes, and the distance from the spray head to the axis of the rear roller is the same as the distance from the lotus root tube holes to the axis of the rear roller. A first solenoid valve is provided on the water outlet pipe, and the first solenoid valve is 10 cm to 15 cm away from the spray head.

[0006] Furthermore, it also includes a water pump and an air compressor. The water inlet end of the water pump is connected to a water pool, and the water outlet end of the water pump is connected to the high-pressure water tank through a water inlet pipe. The air compressor is connected to the upper part of the high-pressure water tank through an air pipe.

[0007] Further, a second solenoid valve is provided on the water inlet pipe, and the air pipe is connected to the exhaust valve through a tee joint.

[0008] Further, a drain valve is provided at the lower part of the high-pressure water tank.

[0009] Further, a liquid level gauge is provided at the upper part of the high-pressure water tank.

[0010] Further, a proximity switch is provided on the rear roller bearing seat. The proximity switch is installed on the rear roller bearing seat through a second bracket, and the proximity switch is on the side of the nozzle.

[0011] Advantages of this application: By installing a nozzle on the bearing seat on one side of the rear roller, when the rear roller rotates, the bagasse in the lotus root tube holes is flushed out by high-pressure water flow, avoiding blockage of the lotus root tube holes caused by excessive bagasse. The water spraying interval of the nozzle is detected by the proximity switch, and the flushing water flow is pressed out by high-pressure air. Compared with direct connection of a water pump, it has a higher response speed and can dredge the lotus root tube holes when the rear roller is rotating. Description of the Drawings

Detailed Embodiments

[0015] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Among them, the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0017] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0018] As Figures 1 to 2 shown, an anti-blocking device for the lotus root tube holes of the rear roller of a squeezing machine according to an embodiment of the present utility model includes: a rear roller bearing seat 1, a rear roller 2, a spray head 3, and a high-pressure water tank 4. The rear roller 2 is provided with lotus root tube holes 6. Both ends of the rear roller 2 are installed on the frame through the rear roller bearing seat 1; the spray head 3 is connected to the bottom of the high-pressure water tank 4 through a water outlet pipe 5, and the spray head 3 is installed on the rear roller bearing seat 1 through a first bracket 7. The spray head 3 faces the lotus root tube holes 6, and the distance from the spray head 3 to the axis of the rear roller 2 is the same as the distance from the lotus root tube holes 6 to the axis of the rear roller 2. A first solenoid valve 8 is provided on the water outlet pipe 5, and the first solenoid valve 8 is 10 cm to 15 cm away from the spray head 3.

[0019] After being multi-pressed, the sugarcane shreds will become crushed and are likely to block the lotus root tube holes 6 of the rear roller 2 during discharge. Therefore, in this device, the spray head 3 is installed on the rear roller bearing seat 1, and the distance from the spray head 3 to the axis of the rear roller 2 is the same as the distance from the lotus root tube hole 6 to the axis of the rear roller 2. When the rear roller 2 rotates, the lotus root tube holes 6 will successively pass by the spray head 3, and the spray head 3 sprays high-pressure water flow to one side of the lotus root tube holes 6, thereby flushing the sugarcane residues accumulated in the lotus root tube holes 6, so that the sugarcane residues are discharged from the lotus root tube holes 6 after being loosened. In order to improve the flushing effect, the pressure of the water flow is relatively large. If it is always turned on, it will not only cause waste of water resources, but also lead to water flow cost reduction, increase the moisture content of the sugarcane residues, and the splashing water flow is also likely to enter the bearing bush, damaging the oil film in the bearing bush. Therefore, the spray head 3 can only spray water when the lotus root tube holes 6 pass by. The response speed of the traditional water pump is slow and cannot meet the requirement of flushing the lotus root tube holes 6 in the rotating state. Therefore, this application uses high-pressure air as the pressure source, and the water is pressed out from the high-pressure water tank 4. Because the water pump start-up step is omitted, the response speed is faster, and the first solenoid valve 8 is close to the spray head 3. After the first solenoid valve 8 is opened, the water flow can be sprayed out from the spray head 3 faster. At the same time, it is cooperated with the proximity switch 17 to detect whether the lotus root tube holes 6 are approaching in front of the spray head 3. When the lotus root tube holes 6 approach, the proximity switch 17 will change from the approaching state to the away state. At this time, a time delay is set through the PLC controller, so that when the lotus root tube holes 6 rotate from the position of the proximity switch 17 to the position of the spray head 3, the first solenoid valve 8 is opened, so that the water flow sprayed out by the spray head 3 just shoots into the lotus root tube holes 6. At the same time, the opening time of the first solenoid valve 8 is controlled through the PLC controller, so that when the lotus root tube holes 6 move out of the area of the spray head 3, the first solenoid valve 8 is closed and the spray head 3 stops spraying. Through the above operations, the spray head 3 only sprays water when the lotus root tube holes 6 pass by, which can reduce water consumption, prevent the water flow from splashing and affecting the operation of the equipment, and can also be dredged every 3 to 5 minutes through the PLC controller to further reduce water consumption, and can also use the gap to replenish water to the high-pressure water tank 4 to ensure the water storage in the high-pressure water tank 4.

[0020] In a specific embodiment, as Figure 1 shown, it further includes a water pump 9 and an air compressor 10. The water inlet end of the water pump 9 is connected to the water pool, the water outlet end of the water pump 9 is connected to the high-pressure water tank 4 through a water inlet pipe 12, and the air compressor 10 is connected to the upper part of the high-pressure water tank 4 through an air pipe 11. When the water storage in the high-pressure water tank 4 is less, the high-pressure water tank 4 can be replenished with water through the water pump 9, and the air compressor 10 can automatically control the air pressure in the high-pressure water tank 4. When the air pressure in the high-pressure water tank 4 is relatively low, compressed air can be filled through the air compressor 10. When the air pressure in the high-pressure water tank 4 is relatively high, part of the air is discharged through the exhaust valve 14, so as to ensure that the air pressure in the high-pressure water tank 4 is at an appropriate pressure.

[0021] In a specific embodiment, a second solenoid valve 13 is provided on the water inlet pipe 12. After the high-pressure water tank 4 is replenished with water by the water pump 9, the second solenoid valve 13 is closed to prevent the air in the high-pressure water tank 4 from being discharged through the water pump 9. The air pipe 11 is connected to the exhaust valve 14 through a tee joint. When the high-pressure water tank 4 is at a relatively high level, part of the air is discharged through the exhaust valve 14, so as to ensure that the air pressure in the high-pressure water tank 4 is at an appropriate pressure.

[0022] Preferably, a drain valve 15 is provided at the lower part of the high-pressure water tank 4. When it is necessary to empty the high-pressure water tank 4, the water can be discharged through the drain valve 15.

[0023] Specifically, a liquid level gauge 16 is provided at the upper part of the high-pressure water tank 4, so as to facilitate the controller to obtain the liquid level height information of the high-pressure water tank 4 and facilitate judging whether water replenishment is needed.

[0024] In a preferred embodiment, as Figure 2 shown, a proximity switch 17 is provided on the rear roll bearing block 1. The proximity switch 17 is installed on the rear roll bearing block 1 through a second bracket 18. The proximity switch 17 is on one side of the nozzle 3. The proximity switch 17 adopts a commercially available non-contact proximity switch 17, which senses whether the coupling cylinder hole 6 passes through the position of the proximity switch 17 by generating an alternating magnetic field. And since the proximity switch 17 is in front of the nozzle 3, after the proximity switch 17 senses the coupling cylinder hole 6, it can improve the feedback to the PLC controller, and the PLC controller delays to open the first solenoid valve 8, so that the water flow sprayed by the nozzle 3 just enters the coupling cylinder hole 6.

[0025] Certainly, the present application can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present application.
