Description

Technical Field

[0001] This utility model relates to the field of edible oil processing technology, and in particular to a cleaning device for a primary filtration machine of edible oil. Background Technology

[0002] Currently, edible oils such as peanut oil and tea oil are mainly extracted using two methods: pressing and solvent extraction. Pressing uses physical pressure to directly separate the oil from the oilseeds, without involving any chemical additives, making it more in line with the health-conscious demands of Chinese consumers. The initial oil obtained after pressing peanuts or tea oil is called crude oil. Crude oil contains a large number of impurities and needs to undergo filtration, dehydration, and degumming to obtain the edible oil we need. In the filtration process, to ensure filtration efficiency, it typically undergoes two stages: primary filtration and fine filtration. Primary filtration has high efficiency, removing larger solid impurities, while fine filtration is slower but has higher precision. Currently, primary filtration mainly uses vertical blade filter equipment, such as the vertical blade filter disclosed in Chinese Patent Application No. 201721296959.X. This machine connects a vibrating device to a vertical filter screen, allowing the vibrating device to filter out impurities adhering to the screen. However, in actual use, after filtering impurities from edible oil, a highly adhesive sludge forms on the screen, which cannot be effectively shaken off by the vibrator alone. Therefore, workers need to periodically open the filter and use tools to scrape off the sludge to maintain filtration efficiency. Currently, the main tool used is a shovel. However, due to the close proximity of the vertical filter screens and the depth of the tank, the shovel tip cannot properly adhere to the screen during cleaning, resulting in low cleaning efficiency. Therefore, a cleaning device for edible oil primary filters is needed, featuring an expandable scraper at the front end to press against the vertical filter screen, thus improving cleaning efficiency. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a cleaning device for a primary edible oil filter, which features an expandable scraper at its front end. This scraper is pressed against a vertical filter screen, thereby improving cleaning efficiency.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a cleaning device for a primary filtration machine of edible oil, comprising: a support rod, a transmission rod, a connecting frame, a first gear, a second gear, a rack, a scraper frame, and a scraper. The support rod is hollow inside, and one end of the support rod is fixedly connected to the connecting frame. The first gear and the second gear are mounted on both sides of the connecting frame via a connecting shaft. The rack is slidably connected to the connecting frame, and both sides of the rack are provided with straight teeth, which mesh with the first gear and the second gear respectively. The scraper frame is mounted on the first gear and the second gear respectively, and the scraper is mounted on the scraper frame, with the scraper parallel to the connecting shaft. The transmission rod is slidably mounted in the middle of the support rod, and one end of the transmission rod is connected to one end of the rack.

[0006] Furthermore, the rack has elongated protrusions on both sides, and the connecting frame has guide grooves. The rack is installed in the connecting frame through the protrusions and guide grooves.

[0007] Furthermore, a limiting block is provided at the lower part of the rack, and the cross-section of the limiting block is larger than the cross-section of the rack.

[0008] Furthermore, the upper part of the support rod is provided with a first grip and a second grip, the second grip is fixedly connected to the support rod, the middle part of the first grip is provided with a through hole, the upper part of the transmission rod passes through the through hole, and the middle part of the first grip is connected to the transmission rod by a locking bolt.

[0009] Furthermore, the upper part of the support rod is provided with a square groove for the first grip to slide, and the head of the locking bolt faces the opening direction of the square groove.

[0010] Furthermore, the scraper frame is provided with a dovetail-shaped mounting groove, and the scraper is installed in the mounting groove.

[0011] The beneficial effects of this utility model are as follows: by using a transmission rod to drive the rack to move, and then driving the first gear and the second gear to rotate, the scraper frame is unfolded. When cleaning the vertical filter screen of the primary filter, pressure can be applied to the vertical filter screen on both sides, and the scraper can fit the vertical filter screen more closely. Workers can easily scrape off the oil sludge attached to the vertical filter screen, thus improving the cleaning efficiency. Attached Figure Description

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] like Figures 1 to 5As shown, an embodiment of this utility model provides a cleaning device for a primary filtration machine of edible oil, including: a support rod 1, a transmission rod 2, a connecting frame 3, a first gear 4, a second gear 5, a rack 6, a scraper frame 7, and a scraper 8. The support rod 1 is hollow inside, and one end of the support rod 1 is fixedly connected to the connecting frame 3. The first gear 4 and the second gear 5 are mounted on both sides of the connecting frame 3 through a connecting shaft 9. The rack 6 is slidably connected to the connecting frame 3, and both sides of the rack 6 are provided with straight teeth, which mesh with the first gear 4 and the second gear 5 respectively. The scraper frame 7 is mounted on the first gear 4 and the second gear 5 respectively, and the scraper 8 is mounted on the scraper frame 7, and the scraper 8 is parallel to the connecting shaft 9. The transmission rod 2 is slidably mounted in the middle of the support rod 1, and one end of the transmission rod 2 is connected to one end of the rack 6.

[0022] When filtering edible oil using an existing primary filter, although a vibration device can shake off some of the oil sludge on the filter screen, some high-viscosity oil sludge will continuously accumulate on the side farther from the vibrator, requiring greater pressure to filter the oil. Therefore, workers periodically open the cover to clean the vertical filter screen from the top of the primary filter. During cleaning, the worker stands on top of the primary filter, inserts the cleaning device between the vertical filter screens, and then simultaneously grasps the first handle 13 and the second handle 14. Under the gripping force, the transmission rod 2 drives the rack 6 downwards, thereby simultaneously driving the first gear 4 and the second gear 5 to rotate. 5. The scraper frames 7 on both sides of the connecting frame 3 are extended outward, so that the scraper 8 at the end of the scraper frame 7 presses tightly against the vertical filter screens on both sides. By moving the cleaning device up and down, the scraper 8 continuously scrapes away the oil sludge attached to the vertical filter screens, completing the cleaning of the vertical filter screens. For the vertical filter screens on both sides of the primary filter, only one side needs to be cleaned, and it is not possible to apply pressure to the vertical filter screen by extending the scraper frame 7. However, the operating space on both sides of the primary filter is large, and the worker can easily scrape it clean by using the scraper frame 7 on one side to drive the scraper 8. This allows the device to clean the oil sludge attached to both sides of all the vertical filter screens, so that the primary filter can maintain good filtration efficiency. After scraping off the oil sludge, the slag discharge at the bottom of the primary filter is opened, and the oil sludge is blown to the outside by compressed air. After cleaning the primary filter, the upper cover is closed, the bolts are tightened, and the primary filtration operation of edible oil can continue.

[0023] Specifically, such as Figure 3 As shown, the rack 6 has elongated protrusions 10 on both sides, and the connecting frame 3 has a guide groove 11. The rack 6 is installed in the connecting frame 3 through the protrusions 10 and the guide groove 11. Under the limiting action of the protrusions 10 and the guide groove 11, the rack 6 can only move in a straight line, thereby better driving the first gear 4 and the second gear 5 to rotate. The rack 6 drives the first gear 4 and the second gear 5 to make the scraper 8 fit against the side of the vertical filter screen, thereby improving the cleaning efficiency.

[0024] Specifically, a limiting block 12 is provided at the lower part of the rack 6. The cross-section of the limiting block 12 is larger than that of the rack 6 to prevent the rack 6 from being pulled out between the first gear 4 and the second gear 5, thus preventing the device from malfunctioning.

[0025] In a preferred embodiment, such as Figure 4 , Figure 5 As shown, the upper part of the support rod 1 is provided with a first handle 13 and a second handle 14. The second handle 14 is fixedly connected to the support rod 1. The first handle 13 has a through hole in the middle, through which the upper part of the transmission rod 2 passes. The middle part of the first handle 13 is connected to the transmission rod 2 by a locking bolt 15. During cleaning, the worker holds the first handle 13 and the second handle 14, so that the first handle 13 receives downward force, thereby driving the transmission rod 2 to move down and drive the rack 6, the first gear 4, the second gear 5, etc., so that the scraper 8 fits against the side of the vertical filter screen, improving the cleaning efficiency. When the locking bolt 15 is loosened, the relative position of the transmission rod 2 on the first handle 13 is adjusted according to the distance between the vertical filter screens, so that after the first handle 13 and the second handle 14 come into contact, the scraper frame 7 can be unfolded at a suitable angle for easy cleaning operation. The distance between the vertical filter screens in the primary filter is the same, so it only needs to be adjusted once and then the locking bolt 15 is tightened.

[0026] Preferably, such as Figure 4 , Figure 5 As shown, the upper part of the support rod 1 is provided with a square groove 16 for the first grip 13 to slide, which facilitates the sliding of the first grip 13 on the support rod 1. The head of the locking bolt 15 is facing the opening direction of the square groove 16, which makes it convenient to adjust the tightness of the locking bolt 15 by using an Allen wrench.

[0027] Specifically, the scraper frame 7 is provided with a dovetail-shaped mounting groove, and the scraper 8 is installed in the mounting groove. When the scraper 8 needs to be replaced after a period of use, the scraper 8 can be removed and replaced.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
