Description

Technical Field

[0001] This utility model belongs to the field of sugarcane production and processing technology, and specifically relates to a continuous juice discharge type surface roller juice-blocking ring and pressing device. Background Technology

[0002] In the sugarcane pressing process of the sugarcane industry, the sugarcane press (such as a three-roll press) is the core equipment for extracting sugarcane juice. It separates the juice from the sugarcane through the rotating and squeezing action of the rollers, while simultaneously discharging the pressed sugarcane pith. To ensure the stability of the pressing process and the purity of the juice, juice-retaining rings are usually installed at both ends of the rollers. These rings serve two purposes: firstly, they ensure that the sugarcane raw material remains within the effective pressing area of ​​the rollers, preventing it from escaping the squeezing range; secondly, the juice discharge holes on the rings connect to the juice discharge channels on the rollers. When the rollers press the sugarcane, some sugarcane juice falls downwards into the juice collection device under the influence of gravity and the rollers, while some juice enters the juice discharge channels under pressure. These channels are parallel to the roller axis and connected at both ends to the juice discharge holes on the rings. Therefore, some sugarcane juice flows out from the discharge holes and, blocked by the frame of the sugarcane press, flows downwards into the juice collection device.

[0003] However, the applicant observed that existing sugarcane presses, relying solely on free fall and a juice discharge channel, have low juice discharge efficiency. Some sugarcane juice remains between the juice-retaining ring and the rollers after being pressed out, leading to an increased proportion of juice being reabsorbed by the sugarcane bagasse during the forward transport process, thus reducing pressing efficiency. Therefore, a continuously draining surface roller with a juice-retaining ring is needed. Utility Model Content

[0004] The purpose of this invention is to provide a continuously draining sugarcane roller baffle ring. By opening a second draining hole through the baffle ring body, it overcomes the defect of low juice drainage efficiency in existing sugarcane presses, which leads to some sugarcane juice being reabsorbed by the sugarcane bagasse. The specific technical solution is as follows: A continuously drainable juice-blocking ring for a face roller includes a juice-blocking ring body installed at both ends of a roller. The juice-blocking ring body has a plurality of mounting holes and a first juice-draining hole arranged in a circumferential array. The juice-blocking ring is fixedly installed at both ends of the roller by means of a connector that cooperates with the mounting holes. A juice-draining channel is provided on the roller, and the first juice-draining hole is connected to the juice-draining channel. The juice-blocking ring body has a plurality of second juice holes arranged in a circumferential array, and the second juice holes penetrate the juice-blocking ring body.

[0005] Preferably, the distance between the center of the second drain hole and the center of the drain ring body is greater than the radius of the roller.

[0006] Preferably, the second drain hole is a tapered hole, and the diameter of the second drain hole at the end near the roller is larger than the diameter at the end away from the roller.

[0007] Preferably, the juice-blocking ring body has multiple flow-guiding grooves arranged in a circumferential array on the side near the roller. The flow-guiding grooves are frustum-shaped, with an upper bottom surface and a lower bottom surface at both ends. The flow-guiding grooves are concentric with the second juice discharge holes and correspond one-to-one. The upper bottom surface of the flow-guiding grooves is connected to the second juice discharge holes.

[0008] Preferably, the guide groove and the projected position of the roll on a plane perpendicular to the roll axis are tangent.

[0009] Preferably, the lower bottom edges of the plurality of flow-guiding grooves are tangent to each other.

[0010] A pressing device includes a roller, a frame, and a drive element. The roller is rotatably mounted on the frame, and the drive element is mounted on a frame and connected to one end of the roller. It also includes a continuously draining surface roller with a juice-blocking ring, as described above.

[0011] Compared with existing technologies, this utility model has the following beneficial effects: 1. This invention utilizes a second juice discharge hole on the juice-blocking ring body. When the pressing device presses the sugarcane, some sugarcane juice leaves the pressing device and enters the collection device under the action of the rollers and the juice discharge channel. The remaining sugarcane juice is discharged through the second juice discharge hole on the juice-blocking ring on both sides of the roller under pressure. The discharged sugarcane juice is blocked by the frame and flows downward into the collection device, preventing it from splashing onto the rotating shaft and affecting its rotation. Because the sugarcane juice is discharged in a timely manner, the reabsorption of sugarcane juice by sugarcane bagasse, which would otherwise reduce the juicing rate, can be avoided.

[0012] 2. At the same time, since the juice-retaining ring improves the efficiency of juice discharge, increasing the feed rate of the pressing device will not cause overload. Thus, based on the designed pressing efficiency of the equipment, the working efficiency of the pressing device can be further improved without replacing or adding equipment, thereby increasing output while saving equipment costs.

[0013] 3. This invention features a guide groove on the side of the juice-blocking ring body near the roller. This guide groove is concentric with and corresponds one-to-one with the second juice discharge hole, and the lower edges of the guide grooves are tangent to each other. Therefore, the guide grooves connect to form a circle that encloses the center of the juice-blocking ring body, and this circle is concentric with the juice-blocking ring body. When sugarcane juice flows through the guide groove, it guides the juice towards the second juice discharge hole, further improving the juice discharge efficiency and preventing the juice from being blocked by the juice-blocking ring body under pressure and flowing along the side wall of the juice-blocking ring body, thus avoiding the possibility of some juice flying out of the pressing device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] A sugarcane press is a device that separates the juice from the sugarcane stalk through mechanical compression. Its core principle is to use pressure to break down the sugarcane's fibrous structure, causing the juice to flow out of the cells and simultaneously separating the juice from the bagasse. The sugarcane stalk consists of fibrous cell walls, cell sap (containing sugar), and vascular bundles, with the juice primarily stored within the cells. The core component of the press applies high pressure to the sugarcane entering the equipment. When the pressure exceeds the cell walls' tolerance limit, the cell walls rupture, and the juice flows out naturally, forming "crude juice." Below or around the pressing mechanism, the equipment is equipped with a collection device and a filter. The collection device collects the sugarcane juice; the filter (usually a metal mesh with a pore size of approximately 0.5-1 mm) initially filters out fine bagasse and fiber from the crude juice, preventing impurities from entering subsequent stages.

[0021] Next reference Figures 1 to 3 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: A continuous juice-draining type face roller juice-blocking ring includes a juice-blocking ring body 1 installed at both ends of a roller 6. The juice-blocking ring body 1 has multiple mounting holes 2 and a first juice-draining hole 3 arranged in a circumferential array. The juice-blocking ring is fixedly installed at both ends of the roller 6 by screws and slots. The roller 6 has a juice-draining channel. The first juice-draining hole 3 is connected to the juice-draining channel. When the roller 6 is pressing sugarcane, some sugarcane juice will enter the juice-draining channel under high pressure and then flow out from the first juice-draining hole 3. Finally, the sugarcane juice flows downward into the sugarcane juice collection device under the obstruction of the frame of the sugarcane press.

[0022] The juice-blocking ring body 1 has multiple second-row juice holes 4 arranged in a circumferential array. The second-row juice holes 4 penetrate the juice-blocking ring body 1. After some of the juice is squeezed out, the sugarcane juice that remains between the juice-blocking ring and the roller 6 flows out from the second-row juice holes 4 under pressure. Then, the sugarcane juice flows downward into the sugarcane juice collection device under the obstruction of the sugarcane press frame.

[0023] The distance between the center of the second juice discharge hole 4 and the center of the juice retaining ring body 1 is greater than the radius of the roller 6, so that when the sugarcane juice moves along the axial direction of the roller 6, the sugarcane juice will not encounter any obstruction on the path into the second juice discharge hole 4, thus improving the juice discharge efficiency.

[0024] The second juice outlet 4 is a conical orifice, with the diameter of the end of the second juice outlet 4 near the roller 6 being larger than the diameter of the end away from the roller 6. Since sugarcane juice contains not only juice but also fine bagasse and fiber during pressing, these materials could potentially clog the second juice outlet 4. Therefore, the second juice outlet 4 is designed as a conical orifice, with the smaller diameter end facing the roller 6. According to fluid mechanics principles, at the same flow rate, the fluid velocity is higher at the smaller diameter end (velocity is inversely proportional to cross-sectional area): the higher velocity at the smaller diameter end allows fine bagasse to quickly enter the orifice, reducing impurities' retention near the inlet; the slower velocity at the larger diameter end prevents impurities carried by the sugarcane juice from adhering due to "high-speed impact on the orifice wall," and the wider channel reduces the probability of impurities entangled and clogging, effectively achieving a degree of "self-cleaning" through fluid movement. Simultaneously, the roller 6 generates significant pressure during sugarcane pressing, thus increasing the pressure to drive the sugarcane juice flow, making the second juice outlet 4 less prone to clogging.

[0025] The juice-blocking ring body 1 has multiple flow-guiding grooves 5 arranged in a circumferential array on one side near the roller 6. The flow-guiding grooves 5 are frustoconical, with an upper bottom surface and a lower bottom surface at each end. The flow-guiding grooves 5 are concentric and correspond one-to-one with the second juice discharge holes 4, and the upper bottom surface of the flow-guiding grooves 5 is connected to the second juice discharge holes 4. When sugarcane juice flows through the flow-guiding grooves 5, the flow-guiding grooves 5 can guide the sugarcane juice to the second juice discharge holes 4 through the inclined surfaces, further improving the juice discharge efficiency and preventing the sugarcane juice from being blocked by the juice-blocking ring body 1 under pressure and flowing along the side wall of the juice-blocking ring body 1, which could cause some sugarcane juice to fly away from the pressing device.

[0026] The projection positions of the flow guide groove 5 and the roller 6 on the plane perpendicular to the axis of the roller 6 are tangent. Therefore, when the sugarcane juice moves along the axis of the roller 6, the sugarcane juice will not encounter any obstruction on the path into the flow guide groove 5, but will directly contact the flow guide groove 5, and then flow to the second juice discharge hole 4 under the action of the flow guide groove 5, further improving the juice discharge efficiency.

[0027] The bottom edges of the multiple flow guide grooves 5 are tangent to each other, so the flow guide grooves 5 are connected to form a circle that surrounds the center of the juice-blocking ring body 1. The circle formed is concentric with the juice-blocking ring body 1, which avoids the situation where some sugarcane juice does not receive the effect of the flow guide grooves 5 when it encounters the juice-blocking ring body 1. Therefore, this arrangement can further improve the juice drainage efficiency.

[0028] A pressing device includes a roller 6, a frame, and a drive element. The roller 6 is rotatably mounted on the frame via bearings, and the drive element is bolted to the frame and connected to one end of the roller 6 via a coupling. The pressing device also includes the aforementioned continuously draining type face roller juice-blocking ring.

[0029] The following is the working process of this utility model: The feeding device feeds the processed sugarcane into the pressing device. When the pressing device presses the sugarcane, some of the sugarcane juice leaves the pressing device and enters the collecting device under the action of the rollers 6 and the juice discharge channel. The remaining sugarcane juice is discharged through the second juice discharge holes 4 on the juice baffle rings on both sides of the rollers 6 under pressure. The discharged sugarcane juice is blocked by the frame and flows downward into the collecting device, without splashing onto the rotating shaft and affecting its rotation. Because the sugarcane juice is discharged in time, the situation where the sugarcane juice is reabsorbed by the sugarcane bagasse, resulting in a decrease in the juicing rate, can be avoided, thus ensuring the efficiency of sugarcane juicing.

[0030] During long-term production operations, the applicant discovered that one of the reasons for the limited production efficiency of the old equipment was that the speed of juice discharge affected the speed of feeding, rather than the equipment itself reaching its maximum load. After meeting the initial design workload, the equipment still had a large load margin. Therefore, by adopting the above-mentioned technical features, the juice discharge efficiency and the pressing efficiency of the pressing device can be improved without adding or replacing the equipment. These technical features are also applicable to new technologies.
