DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a multi-stage filtering device for raw materials for liquor production includes a filtering bin 1, a motor 12 is fixedly connected to the middle of the top of the filtering bin 1, a rotating shaft 2 is fixedly connected to the output end of the motor 12, the rotating shaft 2 passes through the top of the filtering bin 1 and extends into the inner cavity of the filtering bin 1, a feeding port 11 is symmetrically provided at the top of the filtering bin 1, a discharging port 13 is provided at the middle of the bottom of the filtering bin 1, a scraper structure 3 is symmetrically fixedly connected to the middle of the outer surface of the rotating shaft 2, a filtering structure 1 4 is fixedly connected to the middle upper part of the inner cavity of the filtering bin 1 and below the scraper structure 3, a centrifugal cylinder 5 is fixedly connected to the bottom end of the rotating shaft 2, a sealing structure 6 is rotatably connected to the bottom end of the centrifugal cylinder 5, and a filtering structure 2 7 is threadedly connected to the bottom of the sealing structure 6.

[0027] In this scheme, the device can perform multi-stage filtration on the raw liquor obtained through fermentation, distillation and other steps in the liquor production process through filtering structure 1 4 in combination with centrifugal drum 5 and filtering structure 2 7, remove some impurities such as suspended matter and sediment, and make the raw liquor clearer and more transparent.

[0028] Specifically, when the device in this scheme is running, the raw wine enters the inner cavity of the filter bin 1 through the two feed ports 11, the output end of the motor 12 rotates, driving the rotating shaft 2 to rotate, and at the same time the scraper structure 3 scrapes off the sediment impurities on the upper end of the filter plate 42, and makes them gather inside the outlet trough 14, and at the same time the rotation of the rotating shaft 2 drives the centrifugal cylinder 5 to rotate, centrifuging the raw wine passing through the filter structure 4 so that the suspended matter inside it adheres to the upper part of the sealing structure 6.

[0029] At the same time, the original wine after the second filtration is thrown out through the side wall of the centrifugal cylinder 5, falls on the top of the filtering structure 2 7, is filtered again, and is finally collected through the discharge port 13.

[0030] See also Figure 6 The scraper structure 3 includes a scraper groove 32 fixedly connected to the middle of the outer surface of the rotating shaft 2, and two front-to-back symmetrical arc-shaped telescopic rods 33 are fixedly connected to the lower right side of the scraper groove 32, and the other ends of the two arc-shaped telescopic rods 33 are fixedly connected to the inclined scraper 31.

[0031] See also Figure 7 The arc-shaped telescopic rod 33 includes an arc-shaped tube 331, the inner cavity of the arc-shaped tube 331 is slidably connected with an arc-shaped spring 332, the bottom end of the arc-shaped spring 332 is fixedly connected with an arc-shaped rod 333, the upper end of the arc-shaped tube 331 is fixedly connected to the right side of the scraping groove 32, and the bottom end of the arc-shaped rod 333 is fixedly connected to the inclined part of the inclined scraper 31.

[0032] Specifically, when the rotating shaft 2 rotates, the inclined scraper 31 and the scraper groove 32 are driven to rotate simultaneously. At this time, the upper surface of the filter plate 42 filters out the sediment in the original wine. When the inclined scraper 31 rotates, the sediment on the upper surface of the filter plate 42 is scraped off and gathered inside the scraper groove 32. When the inclined scraper 31 and the scraper groove 32 rotate to contact the upper end of the triangular baffle 41, the triangular baffle 41 blocks the lower end of the inclined scraper 31 from continuing to rotate. At this time, the inclined scraper 31 no longer continues to rotate, thereby pushing the arc rod 333 to the right. Therefore, the arc rod 333 compresses the arc spring 332 upward and slides upward in the inner cavity of the arc cylinder 331. At this time, the inclined scraper 31 is no longer in contact with the scraper groove 32, and the sediment impurities inside the scraper groove 32 will fall into the collecting tank 43.

[0033] When the scraper groove 32 continues to rotate to 180 degrees with the inclined scraper plate 31, the triangular baffle 41 can no longer block the inclined scraper plate 31, and then the arc spring 332 returns to its original state, pushing the arc rod 333 downward, and at the same time pushing the inclined scraper plate 31 to rotate so that the left inclined surface of the inclined scraper plate 31 contacts the bottom end of the scraper groove 32, and continues to rotate at the same speed to scrape off the sediment above the filter plate 42.

[0034] See also Figure 4 , Figure 5 and Figure 6The filtering structure 4 includes a filter plate 42, the upper surface of the filter plate 42 can contact the bottom end of the inclined scraper 31, and the upper end of the filter plate 42 is symmetrically provided with a collecting groove 43, and the upper rear part of the collecting groove 43 is fixedly connected with a triangular baffle 41, and the bottom of the inner cavity of the collecting groove 43 is fixedly connected with a guide block 44. The upper middle part of the inner wall of the filter bin 1 is located at one end away from the two collecting grooves 43 and the impurity outlet groove 14 is opened, and the ends of the two impurity outlet grooves 14 away from each other are slidably connected with a sealing block 15.

[0035] The right-angled side of the triangular baffle 41 described in this scheme is consistent with the direction of the scraper groove 32 and the inclined scraper 31, so that during the rotation of the inclined scraper 31, the triangular baffle 41 can block the rotation of the inclined scraper 31. The guide blocks 44 described in this scheme are distributed in a triangular shape, and one end of the two guide blocks 44 close to each other is higher than the other end away from each other. When the sediment falls from the scraper groove 32 into the collecting groove 43, the sediment falls into the outlet groove 14 due to the guiding effect of the guide blocks 44. When the filtration is completed, take out 15 to clean the sediment in the outlet groove 14.

[0036] See also Figure 2 and Figure 3 The upper end of the centrifugal cylinder 5 is rotatably connected to the bottom end of the filter plate 42 , and the sealing structure 6 includes a truncated cone 62 rotatably connected to the bottom end of the centrifugal cylinder 5 , and a protrusion 61 is rotatably connected to the upper end of the truncated cone 62 and located in the inner cavity of the centrifugal cylinder 5 .

[0037] When the rotating shaft 2 rotates, the centrifugal cylinder 5 is driven to rotate at the same time, driving the original wine passing through the filter plate 42 to rotate centrifugally. At this time, the suspended matter in the original wine is precipitated and attached to the top of the protrusion 61, and the original wine after centrifugation falls below through the side wall of the centrifugal cylinder 5.

[0038] Specifically, the material of the protrusion 61 in this solution is a rubber material with a large friction coefficient, which can be tightly attached to the bottom of the inner cavity of the centrifugal cylinder 5 and rotate together with the centrifugal cylinder 5.

[0039] See also Figure 3 The filtering structure 2 7 includes a screw 71 threadedly connected to the middle of the bottom end of the truncated cone 62 , a diatomaceous earth filter plate 72 is fixedly connected to the bottom end of the screw 71 , and the outer surface of the diatomaceous earth filter plate 72 is fixedly connected to the inner wall of the filter bin 1 .

[0040] Before the device of this solution starts to operate, the user rotates the round table 62 to drive the protrusion 61 to rise until it is tightly fitted with the inner cavity of the centrifugal cylinder 5, and the protrusion 61 can rotate together with the centrifugal cylinder 5.

[0041] When the filtration is all completed, the user scrapes and cleans the suspended matter attached to the surface of the protrusion 61 by rotating the round table 62 and waits for the next filtration.

[0042] It should be noted that the specific installation method of the motor 12, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0043] The working principle of the utility model is:

[0044] First, the user rotates the table 62 to make the table 62 drive the protrusion 61 to rise until it is tightly fitted with the inner cavity of the centrifugal cylinder 5. Then the user opens the click 12 and delivers the raw wine to be filtered to the feed inlet 11.

[0045] When the motor 12 is working normally, its output end drives the rotating shaft 2 to rotate, and at the same time, the scraper groove 32 drives the inclined scraper 31 to rotate, so that the sediment in the original wine above the filter plate 42 is scraped off and collected in the scraper groove 32. When the bottom end of the inclined scraper 31 contacts the top end of the triangular baffle 41 and the triangular baffle 41 prevents the inclined scraper from continuing to rotate, the arc-shaped telescopic rod 33 structure allows the inclined scraper 31 and the scraper groove 32 to be set at 180 degrees. At the same time, the sediment falls into the collecting groove 43 and falls into the discharge groove 14 through the action of the guide block 44.

[0046] When the scraping groove 32 continues to rotate, the inclined scraper plate 31 is separated from the triangular baffle plate 41 , and then due to the left and right arc-shaped telescopic rod 33 , the inclined scraper plate 31 is sealed with the bottom of the scraping groove 32 , and the sediment above the filter plate 42 continues to be scraped off.

[0047] When the original wine passes through the filter plate 42 and falls into the centrifugal drum 5, the centrifugal drum 5 rotates with the rotating shaft 2, and the suspended matter in the original wine is centrifuged to make it adhere to the top of the protrusion 61. The original wine after centrifugation passes through the side wall of the centrifugal drum 5 and falls onto the diatomaceous earth filter plate 72 below to filter out impurities such as microorganisms again.

[0048] When all the filtering is completed, the user collects the raw wine after multi-stage filtration through the discharge port 13 and waits for subsequent production.

[0049] At the same time, the suspended matter attached to the top of the protrusion 61 and the sediment inside the outlet tank 14 are cleaned up and wait for the next filtration.

[0050] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
