Description

Technical Field

[0001] This utility model relates to the technical field of grain and oil processing equipment, specifically a fine screening and filtration device for grain and oil production. Background Technology

[0002] Edible oil, also known as "cooking oil," refers to animal or vegetable fats used in food preparation. It is liquid at room temperature. Due to factors such as raw material source, processing technology, and quality, most common edible oils are vegetable oils, including rapeseed oil, peanut oil, corn oil, olive oil, soybean oil, walnut oil, and so on. Currently, most edible oils used are produced by oil pressing machines. However, edible oils pressed using existing oil pressing technology generally contain more impurities and require filtration to obtain oil of good quality and color. The accumulation of impurities during filtration can easily clog the filter screen in the filter canister, leading to a decrease in filtration efficiency and effectiveness. Furthermore, the filter residue often contains some adsorbed grain and oil, affecting the yield and causing waste.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a fine screening and filtration device for grain and oil production, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a fine screening and filtration device for grain and oil production, comprising a filter barrel, an oil inlet pipe passing through the side edge of the filter barrel, an oil outlet being provided at the bottom of the filter barrel and a conduit being fixedly installed at the oil outlet, a ring-shaped filter screen being installed inside the filter barrel, and multiple independent oil outlets located in the inner ring of the filter screen, with an assembly pipe movably connected to the oil outlet through an outwardly extending conduit, and each assembly pipe containing a fine filter screen with a smaller pore size than the filter screen.

[0008] Preferably, the conduit at each oil outlet extends outside the filter barrel, and an assembly pipe is movably connected to the bottom of the conduit, with the bottom of the assembly pipe being sealed by a pipe cap.

[0009] Preferably, the assembly tube and the conduit are connected by corresponding threaded grooves and external threads.

[0010] Preferably, the top of the filter bucket is sealed with a cover, and the bottom of the cover is connected to annular blocking seats at intervals via connecting blocks. The radial dimension of the blocking seat is adapted to the radial dimension of the outer peripheral wall of the filter screen and fits against the outer periphery of the filter screen to form a shield. The height of the blocking seat is higher than that of the filter screen, and a disc-shaped filter screen is installed on the top surface of the blocking seat as the inlet for grain and oil filtration, replacing the filter screen for filtration.

[0011] Preferably, it also includes a cover with a cap body that is adapted to the opening size of the filter screen and closes the opening when the cover is closed.

[0012] (III) Beneficial Effects

[0013] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a fine filtration device for grain and oil production, which combines a primary filter screen and a fine filter screen, employing a multi-stage filtration method to make the filtration more thorough and ensure the safety of grain and oil. The primary filter screen is designed to be replaceable to avoid clogging after prolonged use; simultaneously, multiple independent assembly pipes containing the fine filter screens are arranged and can be flexibly disassembled and assembled at the oil outlet, allowing the fine filter screen to be replaced with the required filtration precision as needed and to be quickly replaced after clogging.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-2As shown: A fine screening and filtration device for grain and oil production includes a filter barrel 1, an oil inlet pipe 2 passing through the side edge of the filter barrel 1, an oil outlet 6 opening at the bottom of the filter barrel 1 and a conduit 10 fixedly installed at the oil outlet 6, and a ring-shaped filter screen 7 fixedly installed inside the filter barrel 1, wherein the oil outlet 6 is located in the inner circumference of the filter screen 7, and the grain and oil are filtered and then discharged from the oil outlet 6.

[0022] The filter screen is designed in a ring shape, providing a wider filtration range, and the ring shape makes it less susceptible to localized clogging. The height of filter screen 7 must be higher than the oil inlet pipe 2 to prevent unfiltered grains and oils from being discharged directly.

[0023] like Figure 3-4 As shown, there are multiple oil outlets 6. At each oil outlet 6, a conduit 10 extends outside the filter barrel 1, and an assembly tube 3 is movably connected to the outside of the conduit 10. The bottom of the assembly tube 3 is sealed by a tube cap 11. The assembly tube 3 and the conduit 10 can be assembled by a threaded connection. A finer filter screen 12 with a smaller pore size can be inserted into each assembly tube 3 as needed to achieve fine filtration. Simultaneously, impurities in the grain and oil are generally filtered through the filter screen 7 without clogging. Furthermore, the assembly tube 3 is relatively easy to install and remove. After removal, the conduit 10 can be promptly sealed by the tube cap 11.

[0024] It should be noted that the pipe cap 11 is a conventional structure that is compatible with the diameter of the conduit 10 or the assembly pipe 3, and can be inserted and tightened by squeezing.

[0025] Furthermore, the top sealing cover 4 of the filter bucket 1 is fitted with a cover 4, and the bottom of the cover 4 is connected to an annular blocking seat 5 at intervals via connecting blocks 9. The radial dimension of the blocking seat 5 is adapted to the radial dimension of the outer peripheral wall of the filter screen 7, so that it can fit and abut against the outer periphery of the filter screen 7 to form a barrier. At the same time, when the blocking seat is pressed in, it can also remove impurities that are blocked on the outside of the filter screen 7 to a certain extent.

[0026] Secondly, the height of the blocking seat 5 is higher than that of the filter screen 7, and a disc-shaped filter screen 8 is installed on the top surface of the blocking seat 5 as a seal. Thus, under the action of the blocking seat 5, the filter screen 8 can replace the filter screen 7 for filtration.

[0027] When cleaning of filter screen 8 at the cover 4 is required (due to some degree of blockage), the cover 4 can be removed directly, along with filter screen 8 and the blocking seat 5, allowing filter screen 7 to be used directly. At this time, as shown in the attached... Figure 5 As shown, a cover 4 with a cap 13 is used for sealing, and the cover 13 can close the circular opening of the filter screen 7 when the cover 4 is closed, so that the filter screen 7 can be directly replaced when the filter screen 8 is removed (through the replacement of the cover 4). When the cover 4 is removed, the flow of grain and oil must be temporarily stopped.

[0028] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
