Description

Technical Field

[0001] This utility model belongs to the field of agricultural product processing technology, and specifically relates to a filtration device for the preliminary processing of agricultural products. Background Technology

[0002] Agricultural products are goods produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties. National regulations define primary agricultural products as plants, animals, and their products obtained from agricultural activities, excluding processed products. In the initial processing of agricultural products, filtration devices are required.

[0003] When filtering agricultural products, it is necessary to remove impurities and shriveled produce. Existing filtration devices typically use a blower to deliver purge gas to the agricultural products, thereby removing impurities and shriveled produce and achieving filtration. However, this purge method cannot filter out metallic impurities and stones, and the product tends to clump together during purge, resulting in poor filtration efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for the preliminary processing of agricultural products, which can solve the problems of not being able to filter out metal impurities and stones in agricultural products, as well as the problem of poor separation effect caused by agricultural products agglomerating together.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A filtration device for the preliminary processing of agricultural products, comprising:

[0008] The filter device body includes a housing, and an inlet is provided on the top wall panel of the housing, through which agricultural products can enter the housing.

[0009] The diversion assembly includes a chute, which is fixedly connected to the top wall panel of the housing at the location of the feed inlet, allowing agricultural products to be conveyed through the chute before entering the housing. The chute is inclined downwards from left to right, allowing the agricultural products to flow freely within the chute due to the slope. Multiple magnetic plates are horizontally and evenly fixedly connected to the bottom wall panel of the chute. As the agricultural products flow along the bottom wall panel, they are diverted by the magnetic plates, resulting in a more even distribution of the products within the chute and ensuring a more uniform distribution when transported into the housing. Simultaneously, the flowing agricultural products come into contact with the magnetic plates, which attract and separate any metal impurities from the products.

[0010] The filter assembly includes a first purge pipe and a second purge pipe, both housed within a housing, with the first purge pipe positioned directly above the second purge pipe. Multiple nozzles are mounted on the sidewalls of both the first and second purge pipes. A blower supplies purge gas to the first and second purge pipes. When this purge gas is ejected through the nozzles, it purges the agricultural products that have entered the housing through the feed inlet after being diverted from the chute. During purge, lighter impurities and shriveled agricultural products are blown to the other side, separating them from the normal agricultural products.

[0011] In one or more embodiments of this utility model, partition plates are fixedly connected to the inner sidewalls of the front and rear sidewalls of the conical section of the shell, and the lower end of the partition plate is fixedly connected to the bottom sidewall of the shell. The conical section of the shell is divided by the partition plates so that the agricultural products and the impurities separated by purging can be separated during the purging and filtering of agricultural products.

[0012] In one or more embodiments of this utility model, a first discharge pipe and a second discharge pipe are fixedly connected to the outer wall of the bottom wall panel of the housing. The first discharge pipe and the second discharge pipe are respectively arranged on the left and right sides of the partition plate, and the agricultural products and impurities after purging and separation are discharged through the first discharge pipe and the second discharge pipe.

[0013] In one or more embodiments of this utility model, a guide plate is fixedly connected to the bottom wall panel of the chute near the left end. The guide plate is placed to the left of multiple magnetic plates and guides the agricultural products through the flow.

[0014] In one or more embodiments of this utility model, the guide plate is configured as a V-shaped plate with the opening of the V-shaped plate facing multiple magnetic plates. Multiple diversion holes are evenly provided at the bottom of the guide plate, so that when agricultural products flow through the guide plate, they flow in the chute through the diversion holes, thereby achieving diversion of agricultural products in the chute.

[0015] In one or more embodiments of this utility model, a cover plate is fitted over the top opening of the chute. The cover plate and the chute are threaded together with fixing screws, which facilitate the installation and removal of the cover plate. This allows for easy cleaning of metal impurities adsorbed by the magnetic plate after the fixing screws are removed. A feed pipe is fixedly connected to the cover plate near its left end. The feed pipe is positioned to the left of the guide plate, allowing agricultural products to flow through the feed pipe to the left side of the guide plate. After being guided and diverted by the guide plate, the product then flows through diversion holes to the right side of the guide plate.

[0016] In one or more embodiments of this utility model, the first and second blowing pipes are disposed below the feed inlet and located to the left of the feed inlet, and the outlets of the plurality of nozzles are all disposed facing to the right, so that the agricultural products falling through the feed inlet will not come into contact with the nozzles, thereby making the blowing effect of the nozzles on the agricultural products better.

[0017] In one or more embodiments of this utility model, a gas supply pipe is fixedly connected to the left side of the sidewall of both the first purge pipe and the second purge pipe. An air inlet pipe is fixedly connected to the end of the gas supply pipe away from the first or second purge pipe, and the air inlet pipe is fixedly connected to the left end wall of the housing in a through-hole manner. The purge gas provided by the blower is transported to the gas supply pipe through the air inlet pipe, and then transported to the first and second purge pipes through the gas supply pipe.

[0018] In one or more embodiments of this utility model, a snap-fit ​​groove is provided on the front side wall of the housing, and a filter screen is detachably snapped into the snap-fit ​​groove. The filter screen is used for further screening and filtration of agricultural products that have fallen after being blown down, so as to remove heavier impurities such as stones from the agricultural products. The filter screen is inclined from left to right upward, so that the agricultural products can be filtered and screened as they flow on the filter screen. The lower end of the filter screen abuts against the upper end of the partition plate, so that the filter screen and the partition plate can separate the housing. Most impurities and shriveled agricultural products are blown by the nozzle to the right side of the filter screen and discharged through the second discharge pipe. After being screened again on the filter screen, the agricultural products are discharged through the first discharge pipe.

[0019] In one or more embodiments of this utility model, the right end of the filter screen is positioned below the feed inlet and towards the right, so that agricultural products can still fall onto the filter screen after being swept by the nozzle. A limiting plate is fixedly connected to one end of the filter screen on the outside of the housing, which facilitates the assembly and disassembly of the filter screen.

[0020] Compared with the prior art, this utility model uses a diversion component to divert agricultural products while filtering out metal impurities in the agricultural products. This ensures that the agricultural products are evenly diverted before entering the filtration device for filtration, thereby improving the filtration effect of the purging gas on the agricultural products. Furthermore, the purged agricultural products will be filtered again through a filter screen to remove heavier impurities such as stones. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1-4 As shown, a filtration device for coarse processing of agricultural products in one embodiment of the present invention includes a filtration device body 1, a diversion component 2, and a filtration component 3.

[0033] like Figures 1-4 As shown, the filter body 1 includes a housing 11, and an inlet 12 is provided on the top wall of the housing 11, through which agricultural products can enter the housing 11.

[0034] like Figure 3 and Figure 4 As shown, partition plates 13 are fixedly connected to the inner walls of the front and rear side panels of the conical section of the housing 11, and the lower end of the partition plates 13 is fixedly connected to the bottom wall of the housing 11. The conical section of the housing 11 is divided by the partition plates 13 so that the agricultural products and the impurities separated by purging can be separated during the purging and filtering of agricultural products.

[0035] like Figure 3 and Figure 4 As shown, a first discharge pipe 14 and a second discharge pipe 15 are fixedly connected to the outer wall of the bottom wall panel of the housing 11. The first discharge pipe 14 and the second discharge pipe 15 are respectively located on the left and right sides of the partition plate 13. The agricultural products and impurities after purging and separation are discharged through the first discharge pipe 14 and the second discharge pipe 15 respectively.

[0036] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the diversion component 2 includes a chute 21, which is fixedly connected to the top wall panel of the housing 11 at the location of the feed inlet 12, so that agricultural products need to be conveyed through the chute 21 before entering the housing 11. The chute 21 is inclined downwards from left to right so that the agricultural products can flow freely within the chute 21. Multiple magnetic suction plates 22 are evenly fixedly connected horizontally on the bottom wall panel of the chute 21, so that when the agricultural products flow on the bottom wall panel of the chute 21, they are diverted by the multiple magnetic suction plates 22, so that the agricultural products can be evenly distributed when flowing on the chute 21, so that the agricultural products conveyed to the housing 11 through the chute 21 are evenly distributed. At the same time, when the agricultural products flow, they come into contact with the magnetic suction plates 22, and the magnetic suction plates 22 can adsorb metal impurities in the agricultural products, so that the metal impurities are separated from the agricultural products.

[0037] like Figure 6 and Figure 7 As shown, a guide plate 23 is fixedly connected to the bottom wall panel of the chute 21 near the left end. The guide plate 23 is placed on the left side of multiple magnetic plates 22, and the agricultural products are diverted and guided by the guide plate 23.

[0038] like Figure 6 and Figure 7 As shown, the guide plate 23 is set as a V-shaped plate with the opening of the V-shaped plate facing multiple magnetic plates 22. Multiple diversion holes 24 are evenly opened at the bottom of the guide plate 23, so that when agricultural products flow through the guide plate 23, the agricultural products flow through the diversion holes 24 in the chute 21, thereby realizing the diversion of agricultural products in the chute 21.

[0039] like Figures 1-4 As shown, a cover plate 25 is attached to the top opening of the chute 21. A fixing screw 27 is threaded onto the cover plate 25 and the chute 21. The fixing screw 27 facilitates the installation and removal of the cover plate 25, allowing for easy cleaning of metal impurities adsorbed by the magnetic plate 22 after removal. A feed pipe 26 is fixedly connected to the cover plate 25 near its left end. The feed pipe 26 is located on the left side of the guide plate 23, allowing agricultural products to flow through the feed pipe 26 to the left side of the guide plate 23. After being guided and diverted by the guide plate 23 on the left side, the product flows through the diversion hole 24 to the right side of the guide plate 23.

[0040] like Figures 3-5As shown, the filter assembly 3 includes a first purge pipe 31 and a second purge pipe 32. Both the first purge pipe 31 and the second purge pipe 32 are disposed inside the housing 11, with the first purge pipe 31 positioned directly above the second purge pipe 32. Multiple nozzles 33 are installed on the side walls of both the first purge pipe 31 and the second purge pipe 32. A blower supplies purge gas to the first purge pipe 31 and the second purge pipe 32. When the purge gas in the first purge pipe 31 and the second purge pipe 32 is ejected through the nozzles 33, it can purge the agricultural products that have entered the housing 11 through the feed inlet 12 after being diverted from the chute 21. During purge, lighter impurities and shriveled agricultural products are blown to the other side, thus separating the impurities and shriveled agricultural products from the qualified agricultural products. By setting up the first purge pipe 31 and the second purge pipe 32, the agricultural products inside the shell 11 can be purged multiple times. At the same time, multiple nozzles 33 are provided so that the purge gas can cover the agricultural products inside the shell 11, thereby improving the filtration effect of the agricultural products during purge.

[0041] like Figure 4 As shown, the first purge pipe 31 and the second purge pipe 32 are located below the feed inlet 12 and to the left of the feed inlet 12. The outlets of the multiple nozzles 33 are all oriented to the right so that the agricultural products falling through the feed inlet 12 will not come into contact with the nozzles 33, thus making the purge effect of the nozzles 33 on the agricultural products better.

[0042] like Figure 3 and Figure 5 As shown, air supply pipes 34 are fixedly connected to the left side of the sidewalls of both the first purge pipe 31 and the second purge pipe 32. An air inlet pipe 35 is fixedly connected to the end of the air supply pipe 34 away from the first purge pipe 31 or the second purge pipe 32. The air inlet pipe 35 is fixedly connected to the left end wall of the housing 11 through the air supply pipe 35. The purge gas provided by the blower is delivered to the air supply pipe 34 through the air inlet pipe 35, so that it can be delivered to the first purge pipe 31 and the second purge pipe 32 through the air supply pipe 34.

[0043] like Figure 4 and Figure 6As shown, a snap-fit ​​groove 37 is provided on the front wall of the housing 11. A filter screen 36 is detachably snapped into the snap-fit ​​groove 37. The filter screen 36 is used to further screen and filter the agricultural products that fall after being blown down, so as to remove heavier impurities such as stones. In order to enable this device to filter different agricultural products, the easy disassembly and assembly of the filter screen 36 allows it to be replaced according to the agricultural products being filtered, thus improving the practicality of the device. The filter screen 36 is inclined from left to right upward, so that the agricultural products can be filtered and screened as they flow on the filter screen 36. The lower end of the filter screen 36 abuts against the upper end of the partition plate 13, so that the filter screen 36 and the partition plate 13 can separate the housing 11. Most of the impurities and shriveled agricultural products are blown to the right side of the filter screen 36 by the nozzle 33 and discharged through the second discharge pipe 15. After being screened again on the filter screen 36, the agricultural products are discharged through the first discharge pipe 14.

[0044] like Figure 4 As shown, the right end of the filter screen 36 is positioned below the feed inlet 12 on the right side, so that agricultural products can still fall onto the filter screen 36 after being swept by the nozzle 33. A limiting plate 38 is fixedly connected to one end of the filter screen 36 on the outside of the housing 11, which facilitates the installation and removal of the filter screen 36.

[0045] In use, the purging gas supplied by the blower is delivered to the air supply pipe 34 through the air inlet pipe 35. The air supply pipe 34 delivers the purging gas to the first purging pipe 31 and the second purging pipe 32, and sprays it evenly into the housing 11 through multiple nozzles 33. A matching filter screen 36 is installed in the receiving groove 37 according to the crop to be filtered. The crop is fed in through the feed pipe 26 and flows to the left of the guide plate 23. As the crop flows under the guidance of the guide plate 23, it passes through the diversion hole 24, causing the crop to be diverted and flow in the chute 21. During flow, the crop passes through multiple magnetic suction plates 22, which then hold the crop in place. Metal impurities in the crop are filtered out. At the same time, multiple magnetic suction plates 22 further divert the crop and then evenly transport it into the shell 11 through the feed inlet 12. When the crop falls into the shell 11, the purging gas sprayed from multiple nozzles 33 can purify the crop. Lighter impurities and shriveled crops are purged to the right side of the filter screen 36 and discharged through the second discharge pipe 15. Qualified crops fall onto the filter screen 36 for further filtration. Heavier impurities such as stones are screened out through the filter screen 36. The screened crops are discharged through the first discharge pipe 14, and the screened impurities such as stones are discharged through the second discharge pipe 15.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
