Description

Technical Field

[0001] This utility model relates to the field of sugarcane processing technology, specifically to an energy-saving sugarcane pressing device based on compound enzyme pretreatment. Background Technology

[0002] The sugarcane pressing energy-saving device based on compound enzyme treatment is a device that reduces the toughness of sugarcane fibers through enzymatic hydrolysis. The compound enzyme is usually composed of cellulase, hemicellulase, pectinase, etc. Through the synergistic action of multiple enzymes, it decomposes cellulose, hemicellulose and pectin in the sugarcane cell wall, thereby reducing energy consumption and improving juice extraction efficiency.

[0003] Common pressing equipment relies on high-pressure mechanical force, which consumes a lot of energy and can cause the internal fibers of sugarcane to break. However, the internal fibers of sugarcane are softened after pretreatment with compound enzymes, which reduces the pressure required for pressing, thereby reducing motor power consumption and equipment wear.

[0004] After sugarcane is crushed and enzymatically hydrolyzed, it needs to be pressed using a press and a screen. After pressing, the residual enzyme protein and fiber in the sugarcane bagasse become entangled, forming sticky clumps that clog the screen pores, requiring the machine to be stopped for cleaning. In some cases, high-pressure pulse nozzles are installed on the surface of the press screen to use reverse water flow to flush away the clumps and reduce screen clogging. However, while the use of high-pressure pulse nozzles can reduce agglomeration, when the pulse frequency needs to be appropriately increased, it will cause the high-pressure pump to start and stop frequently, making the motor prone to damage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an energy-saving sugarcane pressing device based on compound enzyme pretreatment, which reduces agglomeration while also reducing motor and electrical energy consumption.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a sugarcane pressing energy-saving device based on compound enzyme pretreatment, including a pressing cylinder, a juice outlet pipe and a cap. The cap is threaded to the pressing cylinder. The pressing cylinder has slots on all four sides of its upper end, and protrusions are in contact with the slots. One of the protrusions is a split structure and is connected by a hinge. The bottom end of one of the protrusions is fixedly connected to an insert rod, which is inserted into the pressing cylinder. A support plate is fixedly connected between the four protrusions. A hydraulic push rod is fixedly connected to the bottom end of the support plate. A pressure plate is fixedly connected to the bottom end of the hydraulic push rod. The bottom end of the pressure plate is uniformly fixedly connected to... The device includes a pressure bar, a pressure plate that contacts a receiving cylinder on the side away from the center, a receiving cylinder with evenly spaced juice outlet holes, a receiving plate at the bottom of the receiving cylinder, a drive motor fixedly connected to the center of the bottom of the pressing cylinder, a receiving plate fixedly connected to the output end of the drive motor, support rods fixedly connected to all four sides of the bottom of the receiving plate, a sliding ball embedded in the end of the support rod away from the receiving plate, a connecting strip fixedly connected to one side of the bottom of the support plate, an electric push rod fixedly connected to one side of the connecting strip, a push plate fixedly connected to the output end of the electric push rod, and combing rods evenly fixedly connected to the side of the push plate near the receiving cylinder.

[0007] As a preferred technical solution of this utility model, an auxiliary rod is fixedly connected to the end of the push plate away from the combing rod. The auxiliary rod is movably inserted into the connecting strip. By setting the auxiliary rod, the stability of the push plate movement can be improved.

At the same time, the water pump draws water from the external environment, which is sprayed out from the through holes after passing through the flexible hose and connecting pipes, and cleans the inner wall of the receiving cylinder.

[0009] As a preferred technical solution of this utility model, the pressing cylinder is provided with a limiting groove in the slot, and a pressure strip is inserted into the limiting groove. The pressure strip contacts the protrusion. By setting the pressure strip, the pressing plate can be further stabilized and the stability of the pressing plate can be improved.

[0010] As a preferred technical solution of this utility model, a connecting cover is fixedly connected to the bottom end of the receiving plate, and an annular cover is in contact with the inner side of the connecting cover. The annular cover is fixedly connected to the bottom side of the pressing cylinder. By setting the annular cover and the connecting cover, it is possible to reduce the entry of debris and water into the annular cover, which would cause the rotation of the support rod to become sluggish.

The connecting rod is fixedly connected to the bottom end of the receiving cylinder. By setting the connecting rod, the receiving cylinder can be easily disassembled and replaced.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The sugarcane pressing energy-saving device based on compound enzyme pretreatment shown includes a pressing cylinder 1, a juice outlet pipe 2, and a sealing cap 3. The sealing cap 3 is threadedly connected to the pressing cylinder 1. A spiral heat pipe is installed inside the pressing cylinder 1 to provide preheating for the closed environment formed by the sealing cap 3 and the pressing cylinder 1, thereby improving pressing efficiency. After the sugarcane is softened by enzymatic hydrolysis, it is placed into the receiving cylinder 10 for pressing. The upper end of the pressing cylinder 1 has four slots 4 on each side, and protrusions 5 are in contact with the slots 4. One of the protrusions 5 has a split structure and is connected by a hinge. The bottom end of one of the protrusions is fixedly connected to an insert rod, and the insert rod is connected to the pressing cylinder. The upper end of the cylinder 1 is inserted, and the receiving cylinder 10 can be opened by means of the support plate 6, which facilitates cleaning. The support plate 6 is fixedly connected between the four protrusions 5. The bottom end of the support plate 6 is fixedly connected to the hydraulic push rod 7. When the hydraulic push rod 7 extends, the pressure plate 8 can squeeze the sugarcane raw material. The bottom end of the hydraulic push rod 7 is fixedly connected to the pressure plate 8. The bottom end of the pressure plate 8 is evenly fixedly connected to the pressure rod 9. The pressure rod 9 can further increase the contact surface between the raw material and the pressure structure, and improve the pressing effect. The receiving cylinder 10 is in contact with the side of the pressure plate 8 away from the center. Juice outlet holes 11 are evenly opened on the receiving cylinder 10. The bottom end of the pressing cylinder 10 contacts a receiving plate 12. A drive motor 13, a stepper motor, is fixedly connected to the center of the bottom end of the pressing cylinder 10. The drive motor 13 can drive the receiving plate 12 to rotate, causing the pressing cylinder 10 to rotate synchronously. The output end of the drive motor 13 is fixedly connected to the receiving plate 12. Support rods 14 are fixedly connected to all four sides of the bottom end of the receiving plate 12. The support rods 14 can provide auxiliary stability to the receiving plate 12. A sliding ball is embedded in the end of the support rod 14 away from the receiving plate 12. The sliding ball can reduce the friction between the pressing cylinder 1 and the support rod 14. A connecting rod is fixedly connected to one side of the bottom end of the support plate 6. A motorized push rod 16 is fixedly connected to one side of the connecting strip 15. A folding cover structure can be set at the motorized push rod 16 to avoid direct contact between the juice and the output end of the motorized push rod 16. A push plate 17 is fixedly connected to the output end of the motorized push rod 16. A combing rod 18 is evenly fixedly connected to the side of the push plate 17 near the receiving cylinder 10. The combing rod 18 can comb out the agglomeration at the juice outlet 11. This process can avoid the reduction of water pump life caused by frequent control of water pump on and off. The combing rod 18 can be directly inserted into the juice outlet 11 by the extension of the motorized push rod 16 to achieve the combing effect.

[0019] Among them, the push plate 17 is fixedly connected to an auxiliary rod 19 at the end away from the combing rod 18. The auxiliary rod 19 is movably inserted into the connecting strip 15. By setting the auxiliary rod 19, the stability of the push plate 17 during movement can be improved.

[0020] The pressure plate 8 has four fixed connections to the upper end of the connecting pipe 20, and the upper end of the connecting pipe 20 is fixedly connected to the fixing plate 21. The upper end of the cover 3 is fixedly connected to the water pump 22, and the output end of the water pump 22 is fixedly connected to the hose 23. The hose 23 is fixedly connected to the fixing plate 21. The connecting pipe 20 has through holes evenly distributed. By setting the connecting pipe 20 and the fixing plate 21, the extension of the hydraulic push rod 7 can be supported. At the same time, the water pump 22 draws water from the external environment and passes it through the hose 23, the fixing plate 21, the connecting pipe 20, and the through holes to achieve the effect of cleaning the inner wall of the receiving cylinder 10.

[0021] The pressing cylinder 1 has a limiting groove in the slot 4, and a pressure strip 24 is inserted in the limiting groove. The pressure strip 24 contacts the protrusion 5. By setting the pressure strip 24, it can provide further limiting on the upper side of the protrusion 5 when the cover 3 is closed, so as to maintain the stability of the protrusion 5 and the support plate 6.

[0022] The bottom end of the receiving plate 12 is fixedly connected to the connecting cover 25, and the inner side of the connecting cover 25 is in contact with the annular cover 26. The annular cover 26 is fixedly connected to the bottom side of the pressing cylinder 1. By setting the annular cover 26 and the connecting cover 25, a shielding structure can be formed, which reduces the amount of juice entering the interior of the annular cover 26 and reduces the stiffness of the support rod 14 during rotation.

[0023] The receiving plate 12 has a through hole at its upper end and a connecting rod 27 is inserted into the through hole. The connecting rod 27 is fixedly connected to the bottom end of the receiving cylinder 10. By setting the connecting rod 27, the receiving cylinder 10 can be disassembled, which is convenient for subsequent removal and cleaning of the receiving cylinder 10 and the inside of the pressing cylinder 1.

[0024] Working principle: Sugarcane raw material that has undergone enzymatic hydrolysis and cutting is put into the receiving cylinder 10, and then the protrusion 5 and support plate 6 are installed and sealed with the cap 3. Then, the hydraulic push rod 7 is activated to extend, so that the pressure plate 8 and pressure rod 9 squeeze the sugarcane raw material. The drive motor 13 can control the rotation of the receiving plate 12 and make the receiving cylinder 10 rotate step by step. Then, the electric push rod 16 extends, so that the combing rod 18 is inserted into the juice outlet hole 11, which breaks up the agglomeration near the juice outlet hole 11, thereby reducing the agglomeration and clogging of the through hole, preventing the juice from flowing together, improving the juice extraction efficiency, and reducing the problem of shortening the life of the water pump 22 caused by the high-frequency switching water pump, thus improving the energy-saving effect. After pressing, the sugarcane bagasse is removed, and the cap 3 is opened as needed. Then the receiving cylinder 10 is removed and the residue is poured out. Further, the water pump 22 can draw water from the external environment and spray it through the hose 23, connecting pipe 20 and through hole to clean the inner wall of the receiving cylinder 10.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
