Description

Technical Field

[0001] This utility model relates to the field of bean product screening technology, and in particular to a raw material screening device for bean food processing. Background Technology

[0002] Soy products are foods made from soybeans, mung beans, green beans, peas, broad beans, and other legumes as the main raw materials. Most soy products are tofu and its derivatives, which are made by coagulating soybean milk. Soybeans are very nutritious, and regular consumption can reduce body fat, increase immunity, and lower the chance of disease.

[0003] In the production and processing of legume foods, it is usually necessary to screen and grade the legume raw materials to obtain high-quality raw materials. In the existing technology, the screening of legume raw materials is usually carried out by vibration. During the vibration process, because the legume raw materials are relatively light, they may be splashed around, and some legume raw materials may be splashed out of the screening equipment, causing unnecessary labor burden for the workers. At the same time, smaller legume raw materials may also be splashed around during vibration, prolonging the time on the screening screen. The screening efficiency needs to be further improved. In view of this, this utility model is proposed.

[0004] Therefore, the above problems are solved by a raw material screening device for processing legume foods. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material screening device for processing legume foods, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support frame is included, a screening mechanism is provided at the top of the support frame, a connecting spring is provided between the support frame and the screening mechanism, a vibration motor is installed on the side wall of the screening mechanism, and the vibration of the vibration motor acts on the screening mechanism.

[0007] Preferably, the screening mechanism includes a frame, the bottom of which is connected to a connecting spring, and a cover is provided on the top of the frame, with a feed inlet on one side of the top of the cover.

[0008] Preferably, the frame is provided with a sieve plate inside, and the inner sidewall of the frame is symmetrically provided with sliding grooves. The sliding grooves are used for sliding connection of the sieve plate. The end face of the sieve plate is provided with a primary filter hole, a secondary filter hole and a tertiary filter hole from left to right.

[0009] Preferably, the inner sidewall of the frame is symmetrically provided with three sliding grooves, which are arranged sequentially from left to right. The interior of the three sliding grooves is provided with a first partition plate, a second partition plate, and a baffle plate sequentially from left to right.

[0010] Preferably, the three grooves are connected to the sliding groove.

[0011] Preferably, the interior of the frame is provided with three upright plates from left to right, and each of the three upright plates has a through hole on its end face. The upright plates divide the interior of the frame into three spaces from left to right, and a fan is provided on the right side of the right upright plate.

[0012] Preferably, each of the three spaces has a discharge port at its bottom, and each of the three spaces has an entrance on its side wall. The outer side wall of the frame is provided with three dust collection boxes, which are aligned with the entrances.

[0013] Preferably, a pipe is provided between the fan and the three dust collection boxes, and the three dust collection boxes are connected to each other through the pipe.

[0014] Preferably, the dust collection box has an opening at one end, which is in contact with the inlet, and a filter screen is provided at the top of the dust collection box, which is slidably connected inside the dust collection box.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, the bottom ends of the first and second partition plates are provided with grooves at their contact surfaces with the sieve plate. The grooves are for the passage of bean products. The first and second partition plates are used to block the rapid passage of bean products, preventing them from entering the frame from the feed inlet without the obstruction of the first and second partition plates, thus failing to perform the screening function. Therefore, the first and second partition plates slow down the passage speed of the bean products, allowing them to contact the filter holes for screening. The grooves are for the passage of bean products, requiring them to adhere to the surface of the sieve plate as they pass through. At the same time, the vibration generated by the vibrating motor prevents the bean products from causing congestion when passing through the grooves, thus affecting the passage of subsequent bean products.

[0017] 2. The end faces of the three upright plates of this utility model are provided with through holes. The diameter of the through holes is smaller than the diameter of the primary filter holes, which prevents the bean products screened by the primary filter holes from mixing with the bean products screened by other spaces through the through holes.

[0018] 3. The screening mechanism of this utility model includes a frame, which is connected to the support frame by a connecting spring. A vibration motor acts on the frame, and the frame is detachably connected to the cover, so that the frame forms a sealed space, which effectively prevents some bean products from splashing out of the frame due to vibration, thus avoiding unnecessary labor burden on the workers.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] In the production and processing of legume foods, it is usually necessary to screen and grade the raw materials to obtain high-quality raw materials. In the existing technology, the screening of legume raw materials is usually carried out by vibration. During the vibration process, because the raw materials of legumes are relatively light, they may be splashed around, and some of them may even be thrown out of the screening equipment, causing unnecessary labor burden for the workers. At the same time, smaller legumes may also spend more time on the screening screen due to splashing during vibration. The screening efficiency needs to be further improved.

[0030] This utility model provides, for example Figures 1 to 8 A raw material screening device for processing bean products is shown, comprising a support frame 1, a screening mechanism 2 is provided at the top of the support frame 1, a connecting spring 3 is provided between the support frame 1 and the screening mechanism 2, and a vibration motor 4 is installed on the side wall of the screening mechanism 2, the vibration of the vibration motor 4 acting on the screening mechanism 2.

[0031] When in use, the support frame 1 is installed in the working area. The support frame 1 supports the screening mechanism 2. The connecting spring 3 of the support frame 1 can ensure that the screening mechanism 2 can shake. At the same time, it is used to connect the support frame 1 and the screening mechanism 2. The vibration motor 4 acts on the screening mechanism 2. The vibration generated by the vibration motor 4 acts on the screening mechanism 2, so that the screening mechanism 2 can shake and screen.

[0032] The screening mechanism 2 includes a frame 201, the bottom end of which is connected to a connecting spring 3, and a cover 203 is provided on the top of the frame 201. A feed inlet 204 is provided on one side of the top of the cover 203.

[0033] In use, the screening mechanism 2 includes a frame 201, which is connected to the support frame 1 via a connecting spring 3. The vibration motor 4 acts on the frame 201. The frame 201 is detachably connected to the cover 203, forming a sealed space. This effectively prevents some bean products from splashing out of the frame 201 due to vibration, thus avoiding unnecessary labor burden on the workers. The feed inlet 204 of the cover 203 is used for bean products to enter the interior of the frame 201, where the bean products are screened.

[0034] The frame 201 is provided with a sieve plate 212 inside. The inner sidewall of the frame 201 is symmetrically provided with sliding grooves 219. The sliding grooves 219 are used for sliding connection of the sieve plate 212. The end face of the sieve plate 212 is provided with a primary filter hole 213, a secondary filter hole 214 and a tertiary filter hole 215 from left to right.

[0035] In use, the sliding grooves 219 are symmetrically opened inside the frame 201 and are inclined. The sieve plate 212 is snapped into the sliding grooves 219. Because the sliding grooves 219 are inclined, the sieve plate 212 is also inclined. The end face of the sieve plate 212 has three levels of filter holes, namely primary filter hole 213, secondary filter hole 214 and tertiary filter hole 215. The diameter of the primary filter hole 213 is smaller than that of the secondary filter hole 214, and the diameter of the secondary filter hole 214 is smaller than that of the tertiary filter hole 215. The sieve plate 212 is inclined. The primary filter hole 213 is located at the higher part of the sieve plate 212, close to the feed inlet 204. The secondary filter hole 214 is located in the middle of the sieve plate 212, while the tertiary filter hole 215 is located at the lower end of the sieve plate 212. This layout facilitates the screening of bean products.

[0036] The bean products enter the frame 201 through the feed inlet 204. The sieve plate 212 screens the bean products. The bean products first pass through the primary filter hole 213, and the bean products with smaller diameters flow out through the primary filter hole 213. The bean products that do not flow out through the primary filter hole 213 flow towards the lower part of the sieve plate 212. When they flow to the secondary filter hole 214, the secondary filter hole 214 lets out the bean products that meet the diameter of the secondary filter hole 214. The bean products that do not flow out through the secondary filter hole 214 flow towards the lower part of the sieve plate 212. When they flow to the tertiary filter hole 215, the tertiary filter hole 215 lets out the bean products, thus completing the screening of the bean products.

[0037] The inner sidewall of the frame 201 is symmetrically provided with three sliding grooves 216, which are arranged from left to right. Inside the three sliding grooves 216, from left to right, there are a first partition plate 209, a second partition plate 210 and a baffle plate 211.

[0038] The three grooves 216 and 219 are connected.

[0039] In use, the three symmetrically opened sliding grooves 216 inside the frame 201 extend sequentially from left to right to ensure that the sliding grooves 216 can communicate with the sliding grooves 219. The first sliding groove 216 is located between the primary filter hole 213 and the secondary filter hole 214. The first sliding groove 216 is shorter in length and is located at a higher position on the sieve plate 212 due to the inclination of the sieve plate 212. The first partition plate 209 is slidably connected inside the first sliding groove 216.

[0040] The second chute 216 is longer than the first chute 216. The second chute 216 is located between the secondary filter hole 214 and the tertiary filter hole 215, in the middle part of the inclined screen plate 212. The second partition plate 210 is slidably connected inside the second chute 216.

[0041] The first partition plate 209 and the second partition plate 210 are both located above the sieve plate 212.

[0042] The third chute 216 is longer than the second chute 216. The third chute 216 is located at the end of the sieve plate 212. The baffle 211 is slidably connected inside the third chute 216, and the baffle 211 is connected to the inside of the sliding groove 219 to prevent the sieve plate 212 from sliding inside the sliding groove 219, thereby limiting the position of the sieve plate 212.

[0043] The bottom ends of the first partition plate 209 and the second partition plate 210 have grooves at their contact surfaces with the sieve plate 212. These grooves are for the passage of bean products. The first partition plate 209 and the second partition plate 210 are used to block the rapid passage of bean products. This prevents bean products from entering the frame 201 from the feed inlet 204 without the obstruction of the first partition plate 209 and the second partition plate 210, which would prevent the bean products from passing through quickly and failing to perform the screening function. Therefore, the first partition plate 209 and the second partition plate 210 slow down the passage speed of the bean products, allowing them to contact the filter holes and be screened. The grooves are for the passage of bean products, requiring them to adhere to the surface of the sieve plate 212 as they pass through. At the same time, the vibration generated by the vibration motor 4 prevents the bean products from causing congestion when passing through the grooves, thus avoiding affecting the passage of subsequent bean products.

[0044] Baffle 211 is located at the end of sieve plate 212 and is used to block the bean product from flowing out of the end of sieve plate 212, so that the bean product passes through the filter holes.

[0045] The frame 201 has three upright plates 217 arranged from left to right inside. Each of the three upright plates 217 has a through hole on its end face. The upright plates 217 divide the interior of the frame 201 into three spaces from left to right. A fan 205 is arranged on the right side of the right upright plate 217.

[0046] In use, the upright plate 217 inside the frame 201 is located below the sieve plate 212. There are three upright plates 217. The first upright plate 217 is aligned with the first partition plate 209, the second upright plate 217 is aligned with the second partition plate 210, and the third upright plate 217 is aligned with the baffle plate 211, so that the frame 201 forms three independent spaces, avoiding the mixing of the screened bean products and increasing the burden on the staff. The bottom of each independent space is provided with a discharge port 202, which is located at the bottom of the frame 201.

[0047] Each of the three upright plates 217 has a through hole on its end face. The diameter of the through hole is smaller than the diameter of the primary filter hole 213, which prevents the bean products filtered by the primary filter hole 213 from mixing with the bean products filtered by other spaces through the through hole.

[0048] The bottom of each of the three spaces is provided with a discharge port 202, and the side wall of each of the three spaces is provided with an inlet 218. The outer side wall of the frame 201 is provided with three dust collection boxes 207, and the three dust collection boxes 207 are aligned with the inlets 218.

[0049] A pipe 206 is provided between the fan 205 and the three dust collection boxes 207, and the three dust collection boxes 207 are connected to each other through the pipe 206.

[0050] The dust collection box 207 has an opening at one end, which is in contact with the inlet 218. A filter screen 208 is provided at the top of the dust collection box 207, and the filter screen 208 is slidably connected inside the dust collection box 207.

[0051] In use, the frame 201 has an inlet 218 inside, which penetrates the side wall of the frame 201. A dust collection box 207 is installed at the inlet 218 on the outside of the frame 201. There are three inlets 218, so there are also three dust collection boxes 207. The dust collection boxes 207 correspond one-to-one with the inlets 218. The three dust collection boxes 207 are connected by a pipe 206. The other end of the pipe 206 is connected to the fan 205. The fan 205 is located on the third vertical plate 217 and inside the frame 201. The frame 201 supports the fan 205.

[0052] During operation, the blower 205 blows air into the frame 201. The blown air flows into the frame 201 through the through hole in the vertical plate 217. The air blown by the blower 205 flows along the bottom of the frame 201 and exits at the discharge port 202. Some of the air flows out through the discharge port 202, while the remaining air continues to flow inside the frame 201. When it passes through the inlet 218, the air flows towards the inlet 218. At the same time, the air flows, which moves the dust on the surface of the bean products and the dust inside the frame 201 towards the inlet 218. The pipe 206 draws air from the dust collection box 207, creating a negative pressure inside the dust collection box 207. This draws air from the frame 201, and in the process of drawing air, it moves dust into the dust collection box 207. The filter screen 208 inside the dust collection box 207 filters the air and filters the dust onto the surface of the filter screen 208.

[0053] The blower 205 near the vertical plate 217 blows air, and the duct 206 provides the air source for the blower 205. The side of the blower 205 near the duct 206 is the air inlet. As is well known, the air inlet is under negative pressure. Therefore, the blower 205 draws air from the dust collection box 207 through the duct 206 to provide the air source for the blower 205. At the same time, the dust collection box 207 is under negative pressure, which can adsorb air.

[0054] The filter screen 208 is slidably connected to the dust collection box 207. After the filter screen 208 has been filtering for a period of time, the filter screen 208 can be pulled out for dust cleaning to avoid clogging.

[0055] Working principle

[0056] The support frame 1 is installed in the working area. The support frame 1 supports the screening mechanism 2. The connecting spring 3 of the support frame 1 can ensure that the screening mechanism 2 can shake. At the same time, it is used to connect the support frame 1 and the screening mechanism 2. The vibration motor 4 acts on the screening mechanism 2. The vibration generated by the vibration motor 4 acts on the screening mechanism 2, so that the screening mechanism 2 can shake and screen.

[0057] The bean products enter the frame 201 through the feed inlet 204. The sieve plate 212 screens the bean products. The bean products first pass through the primary filter hole 213, and the bean products with smaller diameters flow out through the primary filter hole 213. The bean products that do not flow out through the primary filter hole 213 flow towards the lower part of the sieve plate 212. When they flow to the secondary filter hole 214, the secondary filter hole 214 lets out the bean products that meet the diameter of the secondary filter hole 214. The bean products that do not flow out through the secondary filter hole 214 flow towards the lower part of the sieve plate 212. When they flow to the tertiary filter hole 215, the tertiary filter hole 215 lets out the bean products, thus completing the screening of the bean products.

[0058] The bottom ends of the first partition plate 209 and the second partition plate 210 have grooves at their contact surfaces with the sieve plate 212. These grooves are for the passage of bean products. The first partition plate 209 and the second partition plate 210 are used to block the rapid passage of bean products. This prevents bean products from entering the frame 201 from the feed inlet 204 without the obstruction of the first partition plate 209 and the second partition plate 210, which would prevent the bean products from passing through quickly and failing to perform the screening function. Therefore, the first partition plate 209 and the second partition plate 210 slow down the passage speed of the bean products, allowing them to contact the filter holes and be screened. The grooves are for the passage of bean products, requiring them to adhere to the surface of the sieve plate 212 as they pass through. At the same time, the vibration generated by the vibration motor 4 prevents the bean products from causing congestion when passing through the grooves, thus avoiding affecting the passage of subsequent bean products.

[0059] The blower 205 blows air into the frame 201. The blown air flows into the frame 201 through the through hole of the upright plate 217. The air blown by the blower 205 flows along the bottom of the frame 201 and exits at the discharge port 202. Some of the air flows out through the discharge port 202, and the remaining air continues to flow inside the frame 201. When it passes through the inlet 218, the air flows towards the inlet 218. At the same time, when the air flows, it will carry the dust on the surface of the bean products and the dust inside the frame 201 towards the inlet 218. The pipe 206 will draw air from the dust collection box 207, creating a negative pressure inside the dust collection box 207, drawing air from the frame 201. During the air intake process, dust is carried into the dust collection box 207. The filter screen 208 inside the dust collection box 207 filters the air and filters the dust onto the surface of the filter screen 208.

[0060] The blower 205 near the vertical plate 217 blows air, and the duct 206 provides the air source for the blower 205. The side of the blower 205 near the duct 206 is the air inlet. As is well known, the air inlet is under negative pressure. Therefore, the blower 205 draws air from the dust collection box 207 through the duct 206 to provide the air source for the blower 205. At the same time, the dust collection box 207 is under negative pressure, which can adsorb air.

[0061] The filter screen 208 is slidably connected to the dust collection box 207. After the filter screen 208 has been filtering for a period of time, the filter screen 208 can be pulled out for dust cleaning to avoid clogging.

[0062] The support frame 1 is frame-shaped, and the discharge port 202 is located at the bottom of the frame 201. An external receiving component is installed at the discharge port 202. The receiving component is selected according to production needs, including but not limited to a production line or a discharge pipe.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
