Description

Technical Field

[0001] This utility model relates to the field of jujube pulp production technology, and more specifically, to a multi-stage filtration device for jujube pulp. Background Technology

[0002] Jujube pulp is a beverage made from jujube fruits through washing, crushing, and juicing. It is rich in nutrients such as vitamin C, organic acids, and flavonoids, and has high nutritional and medicinal value. However, during the production of jujube pulp, the extracted pulp often contains impurities such as fruit pulp residue, pit fragments, and fiber. These impurities not only affect the taste and quality of the pulp but may also cause sedimentation and spoilage during storage, reducing the product's stability and commercial value. Therefore, efficient filtration of jujube pulp is a crucial step in improving its quality, extending its shelf life, and meeting market demands.

[0003] However, traditional jujube pulp filtration technology has some problems: 1. Single-stage filtration devices have low filtration efficiency and incomplete impurity separation. Furthermore, the filter components are difficult to disassemble and clean, resulting in inconvenient maintenance and short equipment lifespan. 2. The filtration device lacks a dynamic filtration mechanism, and the pulp is prone to accumulation, leading to filter hole blockage, reduced filtration efficiency, and difficulty in separating tiny impurities, which affects product quality.

[0004] Therefore, there is an urgent need for a multi-stage filtration device for jujube pulp to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage filtration device for jujube pulp to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A multi-stage filtration device for jujube pulp includes a housing, wherein a fixed gear is fixedly connected to the inner wall of the housing, and further includes:

[0008] A rotating filter assembly includes a drive column rotatably connected to the outer wall of a fixed gear, a connecting plate fixedly connected to the outer wall of the drive column, a rotating column rotatably connected to the outer wall of the connecting plate, a rotating gear fixedly connected to the outer wall of the rotating column, and the outer wall of the rotating gear meshing with the outer wall of the fixed gear, a support frame fixedly connected to the outer wall of the rotating column, a fixed cover fixedly connected to the outer wall of the support frame, and a feed inlet on the top wall of the fixed cover.

[0009] A multi-stage filtration assembly is installed on the outer wall of the fixed cover.

[0010] As a preferred technical solution of this application, the multi-stage filtration assembly includes an outer filter bucket fixedly connected to the outer wall of the fixed cover, an interval filter bucket fixedly connected to the outer wall of the outer filter bucket, an inner filter bucket fixedly connected to the outer wall of the interval filter bucket, and filter holes evenly distributed on the outer walls of the outer filter bucket, the interval filter bucket, and the inner filter bucket. A threaded tube is fixedly connected to the outer wall of the outer filter bucket, a threaded plug is threadedly connected to the inner wall of the threaded tube, and a rubber ring is fixedly connected to the outer wall of the threaded plug.

[0011] As a preferred technical solution of this application, the inner walls of the spacer filter, inner filter, and outer filter all abut against the outer wall of the rubber ring, and the spacer filter and inner filter are fixedly connected to the fixed cover.

[0012] As a preferred technical solution of this application, a drive motor is fixedly connected to the top wall of the housing, and the output end of the drive motor is fixedly connected to the drive column.

[0013] As a preferred technical solution of this application, the outer wall of the shell is fixedly connected with symmetrically distributed support columns, and the outer wall of the support columns is fixedly connected with support plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. The jujube pulp is filtered sequentially through the inner filter bucket, the interval filter bucket, and the outer filter bucket of the multi-stage filtration components. The filter pores of different sizes can gradually remove impurities of different sizes. Compared with single-stage filtration, the filtration efficiency is higher and the jujube pulp is purer. At the same time, the design of the threaded tube and threaded plug allows for the individual cleaning of impurities in each filter bucket. The rubber ring ensures both sealing and easy disassembly, resulting in low maintenance costs. This solves the problems of low filtration efficiency, incomplete impurity separation, and difficulty in disassembling and cleaning the filter components in the existing single-stage filtration device, which leads to inconvenient maintenance and short equipment life.

[0017] 2. By combining the revolution and rotation of the multi-stage filtration components, the jujube pulp forms a dynamic flow within the filter chamber, preventing filter pore blockage. Simultaneously, the angled rotation generates asymmetrical centrifugal force during the revolution and rotation of the multi-stage filtration components, causing the jujube pulp to flow in a spiral pattern within the filter chamber. This increases the probability of impurities contacting the filter pores, making it easier to separate small particles and improving filtration speed and accuracy. This solves the problems in existing filtration devices where the lack of a dynamic filtration mechanism leads to easy accumulation of pulp causing filter pore blockage, reduced filtration efficiency, and difficulty in separating tiny impurities, thus affecting product quality.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] like Figure 1-5 As shown, the multi-stage filtration device for jujube pulp proposed in this embodiment includes a housing 1, a fixed gear 5 fixedly connected to the inner wall of the housing 1, and further includes:

[0027] The rotating filter assembly includes a drive column 7 rotatably connected to the outer wall of a fixed gear 5. A connecting plate 8 is fixedly connected to the outer wall of the drive column 7. A rotating column 19 is rotatably connected to the outer wall of the connecting plate 8. A rotating gear 6 is fixedly connected to the outer wall of the rotating column 19, and the outer wall of the rotating gear 6 meshes with the outer wall of the fixed gear 5. A support frame 9 is fixedly connected to the outer wall of the rotating column 19, and a fixed cover 10 is fixedly connected to the outer wall of the support frame 9. A feed inlet 11 is opened on the top wall of the fixed cover 10. After the drive motor 4 starts, the output end directly drives the drive column 7 to rotate. Since the drive column 7 is installed at an angle, the connecting plate 8 on its outer wall drives the rotating column 19 to be tilted. At this time, the rotating gear 6 on the outer wall of the rotating column 19 is meshed with the fixed gear 5. When the drive column 7 rotates, on the one hand, it drives the rotating column 19 to revolve around the fixed gear 5 at an angle. On the other hand, due to the gear meshing relationship, the rotating column 19 synchronously generates a self-rotation motion, forming a compound rotation mode.

[0028] A multi-stage filter assembly is installed on the outer wall of the fixed cover 10.

[0029] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the multi-stage filtration assembly further includes an outer filter 12 fixedly connected to the outer wall of the fixed cover 10, a spacer filter 13 fixedly connected to the outer wall of the outer filter 12, an inner filter 14 fixedly connected to the outer wall of the spacer filter 13, and uniformly distributed filter holes 15 formed on the outer walls of the outer filter 12, spacer filter 13, and inner filter 14. A threaded tube 16 is fixedly connected to the outer wall of the outer filter 12, and a threaded plug 17 is threadedly connected to the inner wall of the threaded tube 16. The outer wall of the threaded plug 17 is fixed... With the rubber ring 18 connected, the jujube pulp is poured into the feed inlet 11 and enters the fixed cover 10 placed at an angle. At this time, the outer filter 12, the interval filter 13, and the inner filter 14 revolve and rotate at an angle with the rotating column 19. Under the dual action of centrifugal force and angled rotation, the jujube pulp first passes through the filter hole 15 of the inner filter 14 to filter large particles of impurities, and then passes through the filter hole 15 of the interval filter 13 and the outer filter 12 for fine filtration in stages. The angled rotation causes the pulp to form an irregular flow trajectory in the filter hopper, avoiding the accumulation of impurities and clogging of the filter hole 15.

[0030] like Figure 4 As shown, in a preferred embodiment, based on the above method, the inner walls of the interval filter 13, the inner filter 14 and the outer filter 12 all abut against the outer wall of the rubber ring 18. The interval filter 13 and the inner filter 14 are both fixedly connected to the fixed cover 10. After filtration, the threaded plug 17 on the threaded tube 16 is unscrewed, the rubber ring 18 is released from the seal, and the impurities remaining after the angled rotation can be quickly discharged through the threaded tube 16. The angled structure facilitates the smooth sliding of impurities under the action of gravity.

[0031] like Figure 2 As shown, in a preferred embodiment, based on the above method, a drive motor 4 is fixedly connected to the top wall of the housing 1, and the output end of the drive motor 4 is fixedly connected to the drive column 7, so that the drive column 7 can be rotated through the output end of the drive motor 4.

[0032] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer wall of the housing 1 is further provided with symmetrically distributed support columns 2, and the outer wall of the support columns 2 is provided with support plates 3. The support columns 2 and the support plates 3 provide support for the equipment.

[0033] Specifically, in use, this multi-stage jujube pulp filtration device works as follows: After the drive motor 4 starts, its output directly drives the drive column 7 to rotate. Since the drive column 7 is installed at an angle, the connecting plate 8 on its outer wall causes the rotating column 19 to be tilted. At this time, the rotating gear 6 on the outer wall of the rotating column 19 is engaged with the fixed gear 5. When the drive column 7 rotates, it drives the rotating column 19 to revolve around the fixed gear 5 at an angle. On the other hand, due to the gear meshing relationship, the rotating column 19 also rotates synchronously, forming a compound rotation mode. After the jujube pulp is poured in from the feed inlet 11, it enters the fixed cover 10 placed at an angle. At this time, the outer filter hopper 12... The interval filter 13 and the inner filter 14 rotate at an angle with the rotating column 19. Under the combined action of centrifugal force and angled rotation, the jujube pulp first passes through the filter holes 15 of the inner filter 14 to filter large particles of impurities, and then passes through the filter holes 15 of the interval filter 13 and the outer filter 12 for progressive fine filtration. The angled rotation causes the pulp to form an irregular flow trajectory in the filter hopper, which avoids the accumulation of impurities and blockage of the filter holes 15. After filtration, the threaded plug 17 on the threaded tube 16 is unscrewed, the rubber ring 18 is released from the seal, and the impurities remaining after the angled rotation can be quickly discharged through the threaded tube 16. The angled structure facilitates the smooth sliding of impurities under the action of gravity.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
