Description

Technical Field

[0001] This utility model belongs to the field of press technology, and more specifically, it relates to a press plate device for a press. Background Technology

[0002] Presses are widely used in food processing, biomass treatment, and other fields to apply pressure to materials to achieve solid-liquid separation. In a typical press structure, the pressure plate is a key component, whose surface directly bears and squeezes the material.

[0003] In existing pressing devices, after the pressing operation is completed, the squeezed and dehydrated solid waste often adheres tightly to the surface of the pressing plate. Because existing devices lack an effective automatic cleaning mechanism, this residual waste must be manually scraped and cleaned by operators after the machine is stopped. This manual intervention not only significantly reduces the continuity of equipment operation and work efficiency but also significantly increases the labor intensity and manpower consumption of operators.

[0004] On the other hand, to guide the juice out and potentially perform preliminary filtration, pressing devices typically have a filtration structure near the pressing area. However, existing designs lack convenient, removable auxiliary filtration devices. This results in a large amount of fine solid waste easily clogging or remaining in the filtration structure during the pressing process. After operation, workers not only need to clean the pressing surface but also must expend additional time and effort to thoroughly clean the interior of the fixed or difficult-to-remove filtration devices, a cumbersome and time-consuming process that further reduces the overall efficiency of the equipment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a press plate device for a press, thereby solving the problem of high manual cleaning burden and low efficiency caused by residual waste in the press plate and filter area in existing press plate devices.

[0006] A press plate device includes a press plate body disposed on the upper surface of a base, the press plate body including a press plate column, the top end of the press plate column being provided with a press plate surface; a conical guide cylinder inverted and surrounding the press plate column, the bottom end of the conical guide cylinder being provided with a discharge pipe; a press body disposed above the press plate body by a bracket; and a scraping mechanism fixedly disposed on the inner side of the bracket.

[0007] The scraping mechanism includes two opposing unit sliding members, namely a first sliding member and a second sliding member; a scraper that slides along the length direction of the two unit sliding members, with the bottom end of the scraper contacting the pressure plate surface; and a filter element that is detachably disposed between the conical guide tube and the pressure plate column, located on the lower side of the pressure plate surface.

[0008] Furthermore, the unit slider includes a first hollow box with a through groove on its inner side, and a rod is arranged inside the first hollow box along its length; a slider is sleeved on the rod, and the other end of the slider passes through the through groove; the scraper is detachably arranged between the two sliders.

[0009] Furthermore, the rod in the first sliding member is configured as a threaded rod, and the slider is configured as an internally threaded slider; a motor is provided at the side end of the first sliding member, and the output end of the motor is connected to the threaded rod; the rod in the second sliding member is configured as a smooth rod, and the slider is configured as a smooth slider.

[0010] Furthermore, a second annular groove is provided on the inner side of the opening of the conical guide tube; a first annular groove is provided on the outer edge of the pressure plate surface; the filter element includes an annular mesh plate, a first baffle plate integrally and vertically disposed on the inner edge of the annular mesh plate, a first convex ring provided on the inner side of the first baffle plate, the first convex ring being fitted into the first annular groove; and a second baffle plate integrally and vertically disposed on the outer edge of the annular mesh plate, a second convex ring provided on the outer side of the second baffle plate, the second convex ring being fitted into the second annular groove.

[0011] Furthermore, the scraper includes a second hollow box body with a strip-shaped notch at the bottom; a spring assembly evenly arranged inside the second hollow box body, with a pressure plate connected to the bottom end of the spring assembly; and a T-shaped rubber scraper, the T-shaped rubber scraper including a receiving part built into the second hollow box body and in contact with the pressure plate, the bottom end of the receiving part being integrally provided with a scraping part, the scraping part extending through the strip-shaped notch and contacting the pressure plate surface.

[0012] Furthermore, the conical guide tube is also provided with an inclined guide plate inside, and the lowest end of the guide plate is located at the inlet of the discharge pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) By setting a scraping mechanism above the pressing plate body, including a first sliding member and a second sliding member arranged opposite to each other, and a scraper that can slide on it, the scraping action can be automatically started after the pressing operation is completed without stopping the machine or manual intervention. This realizes the automated cleaning of residues on the surface of the pressing plate, avoids the downtime and high-intensity labor caused by traditional manual scraping, and greatly improves the continuity of equipment operation and production efficiency.

[0015] (2) An elastic mechanism consisting of a spring assembly and a pressure plate is installed inside the scraper, and a T-shaped rubber scraper achieves flexible contact with the pressure plate surface. When the scraper encounters the resistance of material accumulation, the spring can be compressed and deformed, allowing the scraper to make appropriate clearance and avoiding hard scraping that damages the pressure plate surface; at the same time, the elastic pressure ensures that the scraper always fits the pressure plate surface, and even if there are minor unevennesses, it can effectively remove residues, thus balancing cleaning effect and equipment protection.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example:

[0029] like Figures 1-7 As shown, a press plate device for a press includes a press body 5 mounted on top of the press plate body 2 via a bracket 11. In this embodiment, the press body 5 includes at least a hydraulic cylinder 51 and a press plate 51, the configuration of which is existing technology and will not be described in detail here.

[0030] A pressure plate body 2 is mounted on the upper surface of the base 1. The pressure plate body 2 includes a pressure plate column 21, the top of which is provided with a pressure plate surface; and a conical guide cylinder 22, which is inverted and surrounds the pressure plate column 21, with a discharge pipe 24 at its bottom. In this design, the pressure plate column 21 directly bears the material and applies pressure, while the conical guide cylinder 22 guides the liquid generated during the pressing process downwards along its inclined surface into the discharge pipe 24, thereby achieving solid-liquid separation. This ensures effective compression and dehydration of the solid material during the pressing process, and also effectively guides the liquid flow direction through the conical guide cylinder, improving discharge efficiency, reducing liquid residue, and enhancing overall work efficiency.

[0031] Preferably, in order to increase the rapid outflow of liquid, a guide plate 23 is also inclinedly arranged inside the conical guide tube 22, and the lowest end of the guide plate 23 is located at the inlet of the discharge pipe 24.

[0032] The scraping mechanism 3 is fixedly installed on the inner side of the bracket 11. The scraping mechanism 3 includes two opposing unit sliding members, namely a first sliding member 31 and a second sliding member 32. The first sliding member 31 has a threaded rod inside and a slider 303 with an internal thread. Driven by the motor 33, the slider 303 moves stably. The second sliding member 32 has a smooth rod in the rod 302 and a smooth slider in the slider 303. As a guide structure, it ensures the stability of the entire scraper 6 during movement and avoids vertical jumping of the vertical scraper 6.

[0033] In this design, the unit sliding component includes a first hollow box 301 with an inner groove 304. A rod 302 is arranged along the length of the first hollow box 301. A slider 303 is sleeved on the rod 302, with the other end of the slider 303 extending through the groove 304. The scraper 6 is detachably disposed between the two sliders 303. By employing an automated scraping mechanism, the tedious process of manual cleaning is avoided, greatly improving the continuity and efficiency of equipment operation, reducing the workload of operators, and ensuring the cleanliness of the pressing plate surface, thus helping to maintain optimal pressing results.

[0034] The filter element 4 is detachably disposed between the conical guide tube 22 and the pressure plate column 21, located on the lower side of the pressure plate surface. Specifically, the filter element 4 includes an annular mesh plate 41, a first baffle 42, and a second baffle 43, which are respectively embedded in the first annular groove 2101 of the pressure plate column and the second annular groove 2201 of the conical guide tube via a first protruding ring 4201 and a second protruding ring 4301, enabling quick installation and disassembly. By using the annular mesh plate 41 for preliminary filtration, the filter element 4 blocks fine solid waste from entering the liquid flow channel. The embedded design facilitates quick disassembly, cleaning, or replacement of the filter screen during routine maintenance.

[0035] In this design, the scraper 6 includes a second hollow box 61 with a strip-shaped notch 60 at its bottom; a spring assembly 62 evenly arranged inside the second hollow box 61, with a pressure plate 63 connected to the bottom end of the spring assembly 62; and a T-shaped rubber scraper, which includes a receiving part 64 built into the second hollow box 61 and in contact with the pressure plate 63. The bottom end of the receiving part 64 is integrally provided with a scraping part 65, which protrudes through the strip-shaped notch 60 and contacts the pressure plate surface. When the scraper encounters resistance, the spring assembly 62 compresses, causing the scraping part to move aside appropriately, preventing hard scraping damage to the pressure plate surface. Simultaneously, the elasticity provided by the spring assembly 62 ensures that the scraping part 65 always adheres to the pressure plate surface, effectively removing residue even in the presence of minor unevenness. This design protects the pressure plate surface from damage, ensures excellent cleaning results, extends the equipment's service life, and improves work efficiency.

[0036] The working process of this device is as follows:

[0037] Before starting the equipment, ensure that the filter element 4 on the pressure plate body 2 is securely installed by embedding the first annular groove 2101 of the pressure plate column 21 and the second annular groove 2201 of the conical guide tube 22 into the first convex ring 4201 and the second convex ring 4301, respectively. Evenly distribute the material to be pressed onto the pressure plate surface at the top of the pressure plate column, ensuring a flat material distribution to avoid uneven loading that could affect the pressing effect.

[0038] The pressing disc 52 moves downward under the action of the hydraulic cylinder 51, applying pressure to the material. As the pressure increases, the liquid in the material is squeezed out and undergoes preliminary filtration through the annular mesh plate 41 of the filter element 4. Solid residues are trapped above the pressing disc surface, while the filtered liquid passes through the mesh plate and enters the internal space of the conical guide tube 22.

[0039] The filtrate flows downwards along the inner wall of the conical guide tube and is guided by the inclined guide plate 23 to flow towards the inlet of the discharge pipe 24. The guide plate effectively prevents liquid backflow or stagnation, while blocking large particles of impurities from entering the discharge pipe, ensuring that the liquid is smoothly discharged to the collection system.

[0040] When the pressing process ends, the press body 5 returns to its initial position. The control system automatically starts the scraping mechanism 3: the motor 33 drives the threaded rod in the first sliding member 31 to rotate, causing the internal threaded slider to move along the rod 302; the smooth slider in the second sliding member 32 slides synchronously on the smooth rod, playing a guiding role. The scraper 6 slides back and forth along the pressure plate surface under the drive of the two sliders, and its bottom T-shaped rubber scraper 65 is in close contact with the pressure plate surface, gradually scraping off the adhering solid waste and pushing it to the edge.

[0041] During the scraping process, if material accumulation resistance is encountered, the spring assembly 62 inside the scraper is compressed, causing the pressure plate 63 to move the receiving part 64 upward, and the scraping part 65 to make appropriate repositioning to avoid hard scraping and damage to the pressure plate surface. After the resistance is eliminated, the spring returns to its original state, and the scraper blade re-adheres to the pressure plate surface to continue completing the cleaning task, ensuring thorough cleaning without damaging the equipment.

[0042] The scraped solid waste falls into the collection area below the equipment for centralized processing. After operation, the operator can manually remove filter element 4 from the annular groove for rinsing or filter replacement, making maintenance simple and quick. For deep cleaning, the scraping mechanism can be disassembled or the condition of the guide plate can be checked, making overall maintenance time-saving and labor-saving.

[0043] After cleaning and maintenance, the filter components are reinstalled, and the equipment enters standby mode to prepare for the next round of pressing.

[0044] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
