[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 8 As shown, a filtering device for producing sustainable aviation fuel of the present invention comprises a housing 1, a filtering assembly 2, an adjusting assembly 3 and a collecting assembly 4. The filtering assembly 2 is arranged in the housing 1 along the left-right direction. The filtering assembly 2 comprises a plurality of groups of filter plates 21. In this embodiment, two groups are described as an example. Two filter plates 21 are arranged symmetrically in each group. When filtering, the solution enters the housing 1 through the opening at the upper end of the housing 1, and then is filtered by the filtering assembly 2 and discharged from the opening at the lower end of the housing 1. An adjusting assembly 3 for controlling the state change of the filtering assembly 2 is arranged in the housing 1. The adjusting assembly 3 makes the filtering assembly 2 present in two states. When filtering, it presents a first state: the filter plate 21 is horizontal. When cleaning the blockage, the filtering assembly 2 is changed from the first state to the second state. In the second state, the filter plates 21 of the same group are V-shaped. In this embodiment, the two groups of filter plates 21 are symmetrically W-shaped along the housing 1. The collecting assembly 4 is arranged at one end close to the two filter plates 21 of the same group. In the process of changing from the first state to the second state, the filter plates 21 are cleaned and the impurities are collected.

[0030] like Figures 2 to 5 As shown, the above-mentioned adjustment component 3 includes a push plate 31, a hinge plate 33, a slide groove 34 and a driving source 35. The two push plates 31 are symmetrically arranged on the left and right inner walls of the shell 1. The driving source 35 is used to drive the push plates 31 to slide left and right. During the sliding process of the push plates 31, the push plates 31 and the side walls of the shell 1 are always sealed. The sealing method can be achieved by setting the side wall thickness of the shell 1 so that when the push plates 31 slide, the inner wall of the push plates 31 does not extend into the interior of the shell 1, or a telescopic plate is arranged between the push plates 31 and the shell 1. When the inner side of the push plates 31 extends into the interior of the shell 1, the telescopic plate keeps the interior of the shell 1 sealed. The hinge plate 33 is set to slide along the left and right directions of the shell 1. The two adjacent groups of filter plates 21 are hingedly arranged on the left and right sides of the hinge plate 33. The inner walls on the front and rear sides of the shell 1 are provided with slide grooves 34 for the hinge plates 33 to slide left and right. In this embodiment, when two groups are taken as an example, the hinge plates 33 are always located in the middle position of the slide grooves 34.

[0031] like Figures 2 to 5 As shown, a gap a for impurities to pass through is provided at one end of the filter plates 21 of the same group that are close to each other, and a collecting assembly 4 is provided at the gap a. The collecting assembly 4 includes two sealing plates 41, a collecting shell 43 and two scrapers 44. The collecting shell 43 is provided between the two filter plates 21 of the same group. The two filter plates 21 are respectively hinged on the left and right sides of the collecting shell 43. The two sealing plates 41 are respectively provided at one end of the two filter plates 21 that are close to each other. In the first state, when the filter plates 21 are horizontal, the sealing plate 41 seals the gap a between the two filter plates 21 to prevent the solution and impurities from passing through. In the second state, When the filter plates 21 of the same group are in a V-shape, the two sealing plates 41 rotate downward with the filter plates 21 to open the gap a between the filter plates 21. When the two filter plates 21 change from the first state to the second state, the two scrapers 44 scrape the impurities along the upper surface of the filter plates 21 to the middle of the two filter plates 21 of the same group, and the impurities are collected in the collecting shell 43 through the gap a. The side of the scraper 44 close to the filter plate 21 is made of flexible material, preferably rubber, which can effectively reduce the loss of the scraper 44 and the filter plate 21 during scraping, so as to increase the service life of the scraper 44 and the filter plate 21.

[0032] like Figures 4 to 7 As shown, the front and rear ends of the above-mentioned collecting shell 43 are provided with sliders 431, and the front and rear inner walls of the shell 1 are provided with inclined grooves 432. When the filter plates 21 of the same group change from the first state to the second state, the sliders 431 slide along the inclined grooves 432 so that the opening of the collecting shell 43 is always upward. Support frames 45 are provided on the front and rear sides of the opening end of the collecting shell 43. The support frames 45 are T-shaped, and the horizontal sections of the support frames 45 are arranged in the left and right directions. The two ends of the horizontal sections of the two support frames 45 are respectively connected with scrapers 44. The water of the support frames 45 Both ends of the flat section are elastic telescopic rods. When the filter plates 21 of the same group change from the first state to the second state, the horizontal section of the support frame 45 contracts to make the two scrapers 44 move toward the gap a along the two filter plates 21 of the same group respectively, and collect impurities in the gap. When the filter plates 21 of the same group are reset from the second state to the first state, the scrapers 44 are reset under the action of the two elastic telescopic rods of the horizontal section of the support frame 45, and the sealing plate 41 rotates upward with the filter plates 21, and the sealing plate 41 seals the gap a between the two filter plates 21 to prevent the solution and impurities from passing through.

[0033] In order to further solve the problem of excessive oil content in the collected impurities causing waste, such as Figures 5 to 7As shown, a pressure plate 42 is further provided, and the two pressure plates 42 are respectively installed at one end close to the two filter plates 21 of the same group. When the filter plate 21 rotates downward, the two pressure plates 42 rotate in the collection shell 43 toward the left and right side walls of the collection shell 43. When the filter plate 21 is reset to the first state, the two pressure plates 42 rotate upward along with the two filter plates 21. The pressure plates 42 squeeze the collected impurities in the collection shell 43 to discharge the remaining grease in the impurities. The two pressure plates 42 are hinged to the filter plate 21, and a torsion spring is provided at the hinge. The torsion spring is initially provided with a pre-tightening force. The torsion spring makes the pressure plate 42 and the filter plate 21 vertical in a natural state. When cleaning, the filter plates 21 of the same group are When the plate 21 changes from the first state to the second state, when the filter plate 21 rotates downward, the pressure plate 42 rotates with the filter plate 21 to the left and right inner walls of the collecting shell 43. After cleaning, when the filter plate 21 of the same group is reset from the second state to the first state, the filter plate 21 rotates upward. At this time, the pressure plate 42 rotates with the filter plate 21, and the two pressure plates 42 approach each other. The impurities in the collecting shell 43 prevent the two pressure plates 42 from approaching each other. The torsion springs arranged at the hinges between the pressure plates 42 and the filter plates 21 gradually accumulate force. When the filter plate 21 returns to the first state, the torsion springs cause the two pressure plates 42 to continuously squeeze the impurities in the collecting shell 43, causing the grease contained in the impurities to gradually seep out.

[0034] like Figures 1 to 8 As shown, a bottom plate 433 is provided on the lower side of the collecting shell 43, and the bottom plate 433 is hinged to the collecting shell 43 and can rotate downward around the collecting shell 43. When the collecting shell 43 is full of impurities, the bottom plate 433 can be opened to clean the impurities in the collecting shell 43.

[0035] The implementation principle of the filtering device for producing sustainable aviation fuel of the present invention is as follows: when filtering the raw material solution, the solution enters the shell 1 from the opening at the upper end of the shell 1, and then is filtered through the filter plate 21. Impurities in the solution remain on the upper surface of the filter plate 21. As the filtering proceeds, when the impurities on the filter plate 21 accumulate and cause the filter plate 21 to be blocked, the two driving sources 35 drive the push plates 31 on both sides to move toward the middle of the shell 1, and the filter plate 21 changes from the first state to the second state. The filter plate 21 rotates downward from the horizontal state to form a V shape. The sealing plate 41 opens the gap a as the filter plate 21 rotates. The pressing plate 42 rotates to the left and right inner walls of the collecting shell 43 as the filter plate 21 rotates. The collecting shell 43 moves along the path of the inclined slot 432 under the guidance of the slider 431, keeping the opening of the collecting shell 43 always facing upward. When the support frame 45 moves downward as the collecting shell 43 The two telescopic rods of the horizontal section 45 are shortened, and the scraper 44 moves along the upper surface of the filter plate 21 toward the gap a, pushing the impurities on the filter plate 21 to the gap a and then entering the collection shell 43. After cleaning is completed, when the filter plates 21 of the same group are reset from the second state to the first state, the filter plates 21 rotate upward, and the sealing plate 41 closes the gap a as the filter plates 21 rotate, and the pressing plate 42 rotates with the filter plates 21, and the two pressing plates 42 approach each other. Impurities in the collection shell 43 prevent the two pressing plates 42 from approaching, and the torsion springs arranged at the hinges of the pressing plates 42 and the filter plates 21 gradually accumulate force. When the filter plate 21 returns to the first state, the torsion springs cause the two pressing plates 42 to continuously squeeze the impurities in the collection shell 43, so that the grease contained in the impurities gradually seeps out. After multiple cleanings, the impurities in the collection shell 43 are fully collected, and the pressing plates 42 can no longer squeeze the impurities, and the machine is stopped to clean the impurities in the collection shell 43.
