Description

Technical Field

[0001] The utility model relates to the technical field of walnut processing, and particularly relates to a walnut residue filtering and recycling device for walnut oil processing. Background Art

[0002] The walnut residue filtering and recycling device for walnut oil processing is to effectively remove impurities and residues in walnut oil during the production process of walnut oil, and at the same time recycle walnut residues to achieve the maximum utilization of resources.

[0003] In relatively traditional recovery methods, static filtration is mostly used. Static filtration relies on gravity to make walnut oil pass through a filter medium (such as gauze, filter paper, etc.), while walnut residues are intercepted on the medium, resulting in low filtration efficiency and still too high oil content in the filtered walnut residues, which will not only cause waste of walnut oil, but also inconvenience in recycling all walnut residues.

[0004] In existing filtration methods, centrifugal filtration is also used. Centrifugal filtration is a process of separating walnut oil and walnut residues by the centrifugal force generated by a high-speed rotating centrifugal barrel. Under the action of centrifugal force, the less dense walnut oil is thrown towards the wall of the centrifugal barrel and flows out through the filter holes on the wall of the centrifugal barrel, while the denser walnut residues are left in the centrifugal barrel. However, in this method, the impurities remaining in the centrifugal barrel during implementation are likely to block the filter holes of the centrifugal barrel, resulting in low filtration efficiency. Based on this, it is necessary to study a walnut residue filtering and recycling device for walnut oil processing. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a walnut residue filtering and recycling device for walnut oil processing, which effectively solves the problems that in the existing oil residue centrifugal filtration structure, impurities are easy to block the filter holes, resulting in poor filtration effect and low filtration efficiency.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a walnut residue filtering and recycling device for walnut oil processing, including a frame body, a rotary filtering mechanism, a scraping mechanism and a recycling mechanism; the rotary filtering mechanism includes a rotary motor, a rotary shaft and a centrifugal barrel, the rotary shaft is rotatably and sealingly arranged on the frame body, and its bottom is in transmission connection with the rotary motor, the centrifugal barrel is fixedly sleeved in the middle of the rotary shaft, and filter holes are arranged on its inner wall; the scraping mechanism includes a rotating sleeve and a scraping frame; the rotating sleeve is rotatably sleeved on the upper part of the rotary shaft, the scraping frames are uniformly fixed on the outer wall of the rotating sleeve and are in fit with the inner wall of the centrifugal barrel; the recycling mechanism includes a recycling barrel and a discharge port, the recycling barrel is fixed on the frame body and is located outside the centrifugal barrel, a confluence groove is arranged at the bottom of the recycling barrel, and a discharge port is arranged at the lower part of the confluence groove.

[0007] Furthermore, a reinforcing frame is arranged on the outer wall of the recycling barrel, and the reinforcing frame is fixed on the frame body.

[0008] Furthermore, the scraper frame is fixedly connected to the reinforcement frame through a connecting plate.

[0009] Furthermore, a cover plate is provided on the reinforcement frame, and the cover plate seals the gap between the centrifugal barrel and the recovery barrel.

[0010] Furthermore, the centrifugal barrel is a hemispherical hollow structure, and the scraper frame is provided with an arc-shaped scraper adapted to the inner wall of the centrifugal barrel.

[0011] Furthermore, a shaft seat is provided at the upper part of the rotary shaft, and the rotating sleeve is rotatably sleeved on the shaft seat.

[0012] Furthermore, a sealing seat is provided in the middle of the recovery barrel, a rotary seat is provided on the rotary shaft, a sealing groove is provided in the sealing seat, the rotary seat is sleeved in the sealing groove through a sealing ring and can rotate in the sealing groove, and the centrifugal barrel is fixed on the upper part of the sealing seat.

[0013] The beneficial effects of the above technical solutions are as follows: The utility model structurally includes a rotary filtration mechanism, a scraper mechanism and a recovery mechanism. Among them, the rotary filtration mechanism uses a motor to drive the centrifugal barrel to rotate, and separates oil and slag by centrifugal force. Through the cooperation of the rotary filtration mechanism and the scraper mechanism, efficient filtration of walnut slag is achieved. The walnut slag is thrown towards the inner wall by the centrifugal force generated by the rotation in the centrifugal barrel, and the scraper frame closely adheres to the inner wall to scrape off the residue, ensuring the timely recovery of the residue and improving the filtration efficiency.

[0014] During operation, the scraper is fixed or moves at a low speed, while the centrifugal barrel moves at a relatively high speed. There is a speed difference between the scraper and the centrifugal barrel, so that the scraping and cleaning operation of the inner wall of the centrifugal barrel can be realized, ensuring the smoothness of the filter holes. The cleaning operation does not require additional time and power, and the structure is easy to implement and the design is delicate. During implementation, the rotary shaft is configured on the frame body through the rotary seat and the sealing seat structure, and the support effect, sealing performance and stability are good.

[0015] In the utility model, there is a gap between the centrifugal barrel and the recovery barrel. The upper area is sealed by a cover plate. A diversion area is arranged at the bottom of the recovery barrel, and a discharge pipe is arranged at the downstream part of the diversion area, which is convenient for discharging oil externally.

[0016] Therefore, the utility model has a novel structure. Through the cooperation of the rotary filtration mechanism, the scraper mechanism and the recovery mechanism, it can continuously clean and scrape the centrifugal barrel during operation, ensure the smoothness of the filter holes of the centrifugal barrel, eliminate the need for manual cleaning operations, is convenient to use, simple to operate, improves the oil-slag separation efficiency, reduces the skill requirements for operators, realizes the efficient filtration and recovery of walnut slag, and has great economic and environmental benefits.

Specific implementation manner

[0022] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners:

[0023] Embodiment 1. This embodiment aims to provide a walnut residue filtration and recovery device for walnut oil processing, which is mainly used for filtering and separating oil residues in the production process of walnut oil. Aiming at the existing centrifugal filtration structure of oil residues, impurities are easy to block the filter holes, resulting in poor filtration effect and low filtration efficiency. This embodiment provides a walnut residue filtration and recovery device for walnut oil processing.

[0024] As Figure 1 shown in

[0025] a walnut residue filtration and recovery device for walnut oil processing includes a frame body 1, a rotary filtration mechanism, a scraper mechanism and a recovery mechanism; in this embodiment, the frame body 1 bears the support foundation and can be a welded steel frame structure, and provides a foundation for the fixed installation of the rotary filtration mechanism, the scraper mechanism and the recovery mechanism.

[0026] The scraper mechanism includes a rotating sleeve 6 and a scraper frame 7; the rotating sleeve 6 is rotatably sleeved on the upper part of the rotating shaft 2, and the scraper frames 7 are evenly fixed on the outer wall of the rotating sleeve and are in contact with the inner wall of the centrifugal barrel 4; a shaft seat 5 is arranged on the upper part of the rotating shaft 2, and the rotating sleeve 6 is rotatably sleeved on the shaft seat 5 to realize the rotational cooperation between the scraper frame 7 and the rotating shaft 2.

[0027] In this embodiment, the rotating sleeve 6, the scraper frame 7 and the rotating shaft 2 perform differential motion. Since the scraper frame 7 and the rotating shaft 2 are in rotational cooperation, but the rotation of the rotating shaft 2 drives the internal oil to perform centrifugal motion, under the action of the oil, the scraper frame 7 can perform differential motion following the rotating shaft 2, thereby realizing the scraping operation on the centrifugal barrel 4.

[0028] In the specific structure, the centrifugal barrel 4 is a hemispherical hollow structure, and filter holes communicating the internal space of the centrifugal barrel 4 with the gap between the centrifugal barrel 4 and the recovery barrel 8 are arranged on the inner wall of the centrifugal barrel 4. The scraper frame 7 is provided with an arc-shaped scraper adapted to the inner wall of the centrifugal barrel 4. The hemispherical structure can make the two sides higher and the middle lower, which is convenient for the slag to gather at the bottom.

[0029] The recovery mechanism includes a recovery barrel 8 and a discharge port. The recovery barrel 8 is fixed on the frame body 1 and is located outside the centrifugal barrel 4. A confluence groove 9 is arranged at the bottom of the recovery barrel 8, a discharge port is arranged at the lower part of the confluence groove 9, and a discharge pipe 10 extending outward is arranged at the discharge port. The confluence groove is arranged in the outer area at the bottom of the recovery barrel, and it is specifically a diversion groove structure with a sloping side, so that the oil can flow by itself and gather at the discharge port.

[0030] In terms of structure, as Figure 2 shown in, the recovery barrel 8 and the centrifugal barrel 4 are arranged at intervals, and there is a gap between their upper parts. In order to prevent impurities from falling, a reinforcing frame 12 is arranged on the outer wall of the recovery barrel 8, and a cover plate 11 is arranged on the reinforcing frame 12. The cover plate 11 closes the gap between the centrifugal barrel 4 and the recovery barrel 8.

[0031] This embodiment structurally includes a rotary filtration mechanism, a scraper mechanism and a recovery mechanism. Among them, the rotary filtration mechanism uses a motor to drive the centrifugal barrel 4 to rotate, so as to separate oil and slag by centrifugal force. Through the cooperation of the rotary filtration mechanism and the scraper mechanism, efficient filtration of walnut slag is realized. The walnut slag is thrown towards the inner wall by the centrifugal force generated by the rotation in the centrifugal barrel 4, while the scraper frame 7 closely adheres to the inner wall to scrape off the slag, ensuring the timely recovery of the slag and improving the filtration efficiency.

[0032] During use, pour the oil residue into the centrifugal barrel 4 from the middle area, then start the rotary motor 3 to make the centrifugal barrel 4 rotate, thereby generating a centrifugal force, enabling the oil material to quickly pass through the filter holes of the centrifugal barrel 4, while the residue is retained in the centrifugal barrel 4. With the rotation, the oil material inside the centrifugal barrel 4 will exert a force on the scraper, causing it to rotate. However, there is still a speed difference between the scraper frame 7 and the centrifugal barrel 4, thus achieving the purpose of cleaning the inner wall of the centrifugal barrel 4 during the separation process.

[0033] Embodiment 2. This embodiment is basically the same as Embodiment 1, except that the scraping structure of the scraper frame 7 is further described in this embodiment.

[0034] As shown in this embodiment Figure 3 as shown, the reinforcement frame 12 is fixed on the frame body 1, and the scraper frame 7 is fixedly connected to the reinforcement frame 12 through the connecting plate 13. In this embodiment, the inner wall of the centrifugal barrel 4 is scraped by using the method of fixing the scraper. This structure has the characteristics of high scraping and cleaning efficiency and good structural stability.

[0035] Embodiment 3. This embodiment is basically the same as Embodiment 1, except that the connection structure between the rotary shaft 2 and the recovery barrel 8 is further described in this embodiment.

[0036] As shown in this embodiment Figure 4 as shown, a sealing seat 15 is provided in the middle of the recovery barrel 8, a rotary seat 16 is provided on the rotary shaft 2, a sealing groove is provided in the sealing seat 15, the rotary seat is sleeved in the sealing groove through a sealing ring 17 and can rotate in the sealing groove, and the centrifugal barrel 4 is fixed on the upper part of the sealing seat. Through the sealed rotation cooperation between the sealing seat 15 and the rotary seat 16 in this embodiment, the sealing performance of the rotation of the rotary shaft 2 can be improved, and material leakage can be avoided.

[0037] The above-described embodiments of the present invention do not constitute a limitation to the protection scope of the present invention. The basic concept of the present invention is that through the cooperation of the rotary filtering mechanism, the scraper mechanism and the recovery mechanism, the inner wall of the centrifugal barrel 4 can be continuously cleaned and scraped during operation to ensure the smoothness of the filter holes of the centrifugal barrel 4. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
