Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a blackberry juice pressing and filtration device in the blackberry pulp preparation process. Background Technology

[0002] In the blackberry puree preparation process, pressing and filtering is the core step that determines the quality of the puree. It needs to achieve efficient separation of pulp, juice, and impurities while preserving the nutrients in blackberries to the greatest extent. Currently, most blackberry pressing and filtering devices on the market use a single filtration structure, which only completes solid-liquid separation through a single layer of filter screen. It is difficult to accurately intercept impurities of different particle sizes, resulting in the presence of fine pulp fibers or pulp residue in the filtered puree, affecting the clarity and taste of the product.

[0003] Existing equipment also suffers from low filtration efficiency. Blackberry pulp is soft and rich in pectin, which easily adheres to the filter screen and causes blockage during filtration, requiring frequent shutdowns for cleaning. This not only reduces production continuity but also increases labor costs. Furthermore, some equipment lacks a stable vibration-assisted structure, relying solely on gravity for filtration. This results in slow material flow and long filtration cycles, making it difficult to meet the demands of large-scale production.

[0004] Furthermore, there is a contradiction between the sealing performance and ease of disassembly / reassembly of traditional filtration devices. To prevent pulp leakage, some devices adopt a closed structure, leading to cumbersome filter cleaning and equipment maintenance; while devices that are easy to disassemble and assemble often suffer from poor sealing, allowing external impurities to mix into the pulp or causing pulp splashing and waste. These problems not only affect the production efficiency and product quality of blackberry pulp but also limit the adaptability of the device in actual production. Therefore, there is an urgent need for a staged filtration, highly efficient anti-clogging, and easy-to-operate blackberry juice pressing and filtering device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a blackberry juice pressing and filtering device for blackberry pulp preparation, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A blackberry juice pressing and filtering device for blackberry pulp preparation includes a frame, a flange plate fixedly connected to the bottom of the frame, lower seats fixedly connected to the four corners of the top of the frame, springs fixedly connected to the lower seats, upper seats fixedly connected to the tops of the springs, top plates fixedly connected to the four upper seats, filter boxes fixedly connected to the top plates, a vibrator fixedly installed at the bottom of the top plates inside the frame, feed straight pipes and discharge straight pipes connected to the two side walls of the filter boxes, two closely spaced filter hoppers installed in the filter boxes, a filter plate with holes on one side wall of each filter hopper, a groove provided on the side wall of each filter hopper, and a notched collection hopper formed at the bottom of each filter hopper.

[0007] Furthermore, there are a total of four flange plates, which are fixedly installed at the four corners of the frame.

[0008] Furthermore, a sealing cover is rotatably connected to the filter box via a hinge, and two fixing ears are fixedly connected to the sealing cover.

[0009] Furthermore, the filter box has two threaded holes, and the fixing lugs are connected to the threaded holes by bolts.

[0010] Furthermore, the feed straight pipe is located above the filter box, and the discharge straight pipe is located below the filter box.

[0011] Furthermore, the feed straight pipe and the discharge straight pipe are connected to a hose via a valve.

[0012] Furthermore, the diameter of the sieve holes on the two filter plates becomes smaller.

[0013] Compared with the prior art, this utility model provides a blackberry juice pressing and filtering device in the blackberry pulp preparation process, which has the following beneficial effects: This invention employs a graded filtration system of "coarse filtration - fine filtration," where the diameter of the filter plates in the two filter buckets gradually decreases, precisely trapping impurities of different particle sizes. The collection bucket gathers and settles impurities, ensuring the quality of the pulp. The vibration system, combined with a spring, prevents filter screen clogging, accelerates material flow, and improves filtration efficiency and production continuity. The hinge and bolt locking structure of the sealing cap and the snap-fit ​​groove of the filter buckets ensure both sealing performance and ease of assembly and disassembly. The flange plate and hose connection design also enhances the stability and adaptability of the equipment, facilitating the efficient and high-quality production of blackberry pulp.

[0016] 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. Example

[0017] like Figure 1-4 As shown in the figure, a blackberry juice pressing and filtering device in a blackberry pulp preparation process according to an embodiment of the present invention includes a frame 1. A flange plate 2 is fixedly connected to the bottom of the frame 1. Lower seats 3 are fixedly connected to the four corners of the top of the frame 1. Springs 4 are fixedly connected to the lower seats 3. Upper seats 5 are fixedly connected to the top of the springs 4. Top plates 6 are fixedly connected to the four upper seats 5. Filter boxes 7 are fixedly connected to the top plates 6. A vibrator 17 located inside the frame 1 is fixedly installed at the bottom of the top plates 6. After the vibrator 17 is started, the vibration is transmitted to the filter box 7 through the top plates 6. The springs 4 buffer the vibration impact and maintain the amplitude stability to prevent the filter box 7 from shifting due to violent vibration. At the same time, the vibration helps the blackberry pulp to quickly pass through the filter plate 14 to prevent the sieve holes from clogging. The filter box 7 has a feed straight pipe 11 and a discharge straight pipe 12 connected to its two side walls. The filter box 7 has two closely spaced filter hoppers 13 installed inside. One side wall of the filter hopper 13 is a filter plate 14 with holes. The side wall of the filter hopper 13 is provided with a groove 15. The bottom of the filter hopper 13 forms a notched collection hopper 16. The raw material first passes through the first filter plate 14 to coarsely screen out large particles of impurities, and then passes through the second filter plate 14 to finely screen out fine impurities. The graded linkage achieves precise filtration. The collection hopper 16 collects the impurities in the corresponding filter hopper 13, preventing impurities from flowing back and contaminating the filtered raw pulp, thus improving the filtration purity.

[0018] The working principle of the device is as follows: the equipment is fixed by the flange plate 2 at the bottom of the frame 1. After the vibrator 17 is started, it drives the top plate 6 to vibrate. The vibration amplitude is buffered by the spring 4 between the upper seat 5 and the lower seat 3, so that the filter box 7 vibrates stably. The blackberry raw material enters the box through the feed straight pipe 11 above the filter box 7. It first contacts the filter plate 14 of the first filter bucket 13 for preliminary filtration, and then completes fine filtration through the second filter plate 14 with a smaller screen diameter. Impurities are trapped in the filter bucket 13. The filtered impurities are collected by the collection bucket 16 at the bottom of the filter bucket 13. The raw pulp is finally discharged from the discharge straight pipe 12 below the filter box 7. During the filtration process, the sealing cover 8 is sealed by the bolt connection between the fixing ear 9 and the screw hole 10. The slot 15 makes it easy to remove the filter bucket 13 for cleaning impurities. The valves on the feed straight pipe 11 and the discharge straight pipe 12 can control the material conveying speed.

[0019] like Figure 1 As shown, in some embodiments, there are a total of four flange plates 2, which are fixedly installed at the four corners of the frame 1. The flange plates 2 distributed at the four corners can evenly distribute the overall weight of the equipment, prevent the frame 1 from tilting or shifting due to uneven force, and at the same time enhance the connection between the frame 1 and the mounting surface. This provides a reliable foundation support for the stable operation of components such as the vibrator 17 and filter box 7 above, prevents the equipment from shaking or shifting during vibration operation, and ensures the stability of the filtration process.

[0020] like Figure 1 As shown, in some embodiments, a sealing cover 8 is rotatably connected to the filter box 7 via a hinge, and two fixing ears 9 are fixedly connected to the sealing cover 8; this allows the sealing cover 8 to be opened and closed flexibly, facilitating subsequent opening of the box to inspect the filter bucket 13, clean impurities, or check the filtration status; while the two fixing ears 9 fixed on the sealing cover 8 provide a structural basis for locking the sealing cover 8 after it is closed.

[0021] like Figure 3 As shown, in some embodiments, the filter box 7 has two threaded holes 10, and the fixing lug 9 is connected to the threaded holes 10 by bolts. This linkage structure not only makes up for the limitation of the hinge that can only rotate, but also ensures that the internal space of the filter box 7 remains sealed when the vibrator 17 drives the vibration filtration, preventing blackberry pulp from splashing out due to vibration or external dust and impurities from entering the box and contaminating the pulp. At the same time, it provides a convenient disassembly and assembly method for subsequent opening of the sealing cover 8 for maintenance and cleaning of the filter hopper 13, balancing sealing performance and ease of operation.

[0022] like Figure 1As shown, in some embodiments, the feed straight pipe 11 is above the filter box 7, and the discharge straight pipe 12 is below the filter box 7; after the blackberry raw material enters the filter box 7 from the feed straight pipe 11 above, it can flow downward naturally under its own gravity and contact the filter plates 14 of the two filter hoppers 13 in sequence to complete the graded filtration, thus avoiding the accumulation of raw material in the box.

[0023] like Figure 4 As shown, in some embodiments, the feed straight pipe 11 and the discharge straight pipe 12 are connected to a hose via a valve; the flexible connection of the hose can adapt to the pipeline layout under different production scenarios, reduce the spatial position restrictions during equipment installation, improve the adaptability of the overall production line, and will not cause motion interference.

[0024] like Figure 2 As shown, in some embodiments, the diameter of the sieve holes on the two filter plates 14 is reduced; the raw material first contacts the first filter plate 14 with larger sieve holes, which can quickly intercept large particles of impurities such as blackberry pulp and peel, avoid clogging of the subsequent fine sieve holes, and improve the overall filtration efficiency; then it passes through the second filter plate 14 with smaller sieve holes to further remove the fine pulp particles, fibers and other impurities remaining in the pulp, realizing the graded linkage of "coarse filtration first and fine filtration later".

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
