Starch sand washing device for starch production

Abstract

This utility model relates to the technical field of starch processing equipment, specifically a starch washing device for starch production. It includes a fixed support first and a fixed support second, both fixedly mounted on the ground. The fixed support first and fixed support second are equipped with sand removal mechanisms for separating sand from starch slurry. One end of the sand removal mechanism is equipped with a conveying pipe for transporting the starch slurry, and the other end is equipped with a filtering mechanism for filtering sand from the starch slurry. In this utility model, through the sand washing mechanism, when the starch slurry is in the water guide tank, the difference in specific gravity between sand and starch particles causes the sand to automatically accumulate in the strip-shaped through-holes, while the starch particles continue to flow with the starch slurry, thereby removing most of the sand from the starch slurry. The filtering mechanism further filters the starch slurry after most of the sand has been removed, thus maximizing the removal of sand from the starch slurry.

Technical Field

[0001] This utility model relates to the technical field of starch processing equipment, specifically a starch washing device for starch production. Background Technology

[0002] With the development of society and economy, people have higher and higher requirements for the taste of food. Since starch contains glucose, which is one of the energy sources needed by the human body, and starch can enhance the flavor, it is very popular. In the process of starch processing, it is generally necessary to use a starch washing device to remove the fine sand in the starch, so as to prevent the fine sand in the starch from affecting the taste.

[0003] In existing technologies, most sand washing devices remove fine sand from starch by filtering it through a filter screen. However, since the filter screen is fixed inside the equipment, cleaning it after filtration is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a starch washing device for starch production, solving the problem mentioned in the background section that cleaning the filter screen after filtering starch is quite troublesome. To achieve the above objective, this invention provides the following technical solution:

[0005] A starch washing device for starch production includes a fixed support 1 and a fixed support 2 fixedly installed on the ground. The fixed support 1 and the fixed support 2 are equipped with a sand removal mechanism for separating sand from starch slurry. One end of the sand removal mechanism is equipped with a conveying pipe for conveying starch slurry, and the other end of the sand removal mechanism is equipped with a filtering mechanism for filtering sand from starch slurry. The sand removal mechanism is also equipped with a cleaning mechanism for cleaning sand.

[0006] Preferably, the sand removal mechanism includes a water guide channel, which is fixedly connected to a fixed support one and a fixed support two. Several strip-shaped through holes are evenly opened on the inclined section of the water guide channel. A sealing plate is provided below the water guide channel and is closely attached to it. The sealing plate is used to seal the bottom of the strip-shaped through holes to prevent starch slurry from leaking out. A cleaning mechanism is provided on the sealing plate. Two hydraulic rods are fixedly installed on the ground. The movable ends of the two hydraulic rods are at different heights. A support plate is fixedly connected to the movable end of each hydraulic rod. Both support plates are fixedly connected to the sealing plate.

[0007] Preferably, a material conveying pipe is fixedly connected to the higher end of the water guide channel, and a water distribution block is fixedly connected to the inclined section of the water guide channel. Several water distribution holes are evenly opened on the bottom surface of the water distribution block, and a stepped square hole is opened on the lower end of the water guide channel. A filtration mechanism is provided at the stepped square hole.

[0008] Preferably, the filtration mechanism includes a sealing ring, which is fixedly connected in a stepped square hole. A fixing frame is slidably inserted into the sealing ring, and a filter screen is fixedly connected to the fixing frame. Several magnets are evenly arranged at the stepped square hole, and the material of the fixing frame can be attracted by the magnets.

[0009] Preferably, the cleaning mechanism includes a water outlet pipe, which is fixedly connected to the higher end of the sealing plate. A water distribution plate is fixedly connected inside the water outlet pipe, and a plurality of water distribution holes are evenly opened on the water distribution plate. A connecting pipe is also fixedly connected to the water outlet pipe, and a water valve is fixedly connected to the connecting pipe. The water valve is connected to a water supply pipe. A water collection tank is fixedly connected to the lower end of the sealing plate, and end plates are fixedly connected to both ends of the water collection tank. One of the end plates has a water outlet hole.

[0010] Preferably, the water valve includes a three-way valve body, the side port of the three-way valve body is connected to a connecting pipe, the lower port of the three-way valve body is connected to a water pipe, a cap is fixedly connected to the upper port of the three-way valve body, a push rod is slidably connected to the cap, the upper end of the push rod abuts against a water guide groove, a sealing plug is fixedly connected to the lower end of the push rod, a spring in a stretched state is connected between the cap and the sealing plug, a convex ring is provided in the three-way valve body, and the sealing plug abuts against the convex ring to block water from flowing into the connecting pipe.

[0011] Preferably, a collection bucket for collecting starch slurry with sand removed is placed on the second fixed bracket, and the collection bucket is located directly below the filter screen.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the sand washing mechanism allows the sand to automatically accumulate on the sealing surface of the strip-shaped through-holes when the starch slurry flows in the water guide channel, due to the difference in specific gravity between the sand and starch particles. Meanwhile, the starch particles continue to flow with the starch slurry, thereby removing most of the sand from the starch slurry. The filtration mechanism further filters the starch slurry after removing most of the sand, thus maximizing the removal of sand from the starch slurry.

[0014] In this invention, the water valve automatically opens after the sealing plate moves down, thanks to the cleaning mechanism. This allows the water outlet pipe to spray water to wash away the sand accumulated on the sealing plate, thus achieving automatic cleaning of the sealing plate. The fixed frame and filter screen are installed in the stepped square holes by magnetic attraction, making them easy to assemble and disassemble and easy to clean. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution:

[0023] A starch washing device for starch production includes a fixed support 1 and a fixed support 2 fixedly installed on the ground. The fixed support 1 and the fixed support 2 are equipped with a sand removal mechanism 3 for separating sand from starch slurry. One end of the sand removal mechanism 3 is equipped with a conveying pipe 4 for conveying starch slurry, and the other end of the sand removal mechanism 3 is equipped with a filtering mechanism 5 for filtering sand from starch slurry. The sand removal mechanism 3 is also equipped with a cleaning mechanism 6 for cleaning sand.

[0024] In this embodiment, the sand removal mechanism 3 includes a water guide channel 301, which is fixedly connected to a fixed bracket 1 and a fixed bracket 2. A plurality of strip-shaped through holes 302 are evenly opened on the inclined section of the water guide channel 301. A sealing plate 303 is provided below the water guide channel 301 and is closely attached to it. The sealing plate 303 is used to seal the bottom end of the strip-shaped through holes 302 to prevent starch slurry from leaking out. A cleaning mechanism 6 is provided on the sealing plate 303. Two hydraulic rods 304 are fixedly installed on the ground. The movable ends of the two hydraulic rods 304 are at different heights. A support plate 305 is fixedly connected to the movable end of each hydraulic rod 304. Both support plates 305 are fixedly connected to the sealing plate 303.

[0025] In this embodiment, a conveying pipe 4 is fixedly connected to the higher end of the water guide channel 301, and a water dividing block 306 is fixedly connected to the inclined section of the water guide channel 301. A plurality of water dividing holes 307 are evenly opened on the bottom surface of the water dividing block 306, and a stepped square hole 308 is opened on the lower end of the water guide channel 301. A filter mechanism 5 is provided at the stepped square hole 308.

[0026] In this embodiment, the filter mechanism 5 includes a sealing ring 501, which is fixedly connected in the stepped square hole 308. A fixing frame 502 is slidably inserted into the sealing ring 501, and a filter screen plate 503 is fixedly connected to the fixing frame 502. Several magnets 504 are evenly arranged at the stepped square hole 308, and the material of the fixing frame 502 can be attracted by the magnets 504.

[0027] In this embodiment, two handles are symmetrically fixedly connected to the fixing frame 502. The handles facilitate the removal of the fixing frame 502 and the filter screen 503 from the stepped square hole 308.

[0028] In this embodiment, the sealing ring 501 is tightly attached to the outside of the fixing frame 502, thereby preventing starch slurry from flowing out from the gap between the fixing frame 502 and the stepped square hole 308.

[0029] In this embodiment, the cleaning mechanism 6 includes a water outlet pipe 601, which is fixedly connected to the higher end of the sealing plate 303. A water distribution plate 602 is fixedly connected inside the water outlet pipe 601. A plurality of water distribution holes 603 are evenly opened on the water distribution plate 602. A connecting pipe 604 is also fixedly connected to the water outlet pipe 601. A water valve 605 is fixedly connected to the connecting pipe 604. The water valve 605 is connected to the water supply pipe 606. A water collection tank 607 is fixedly connected to the lower end of the sealing plate 303. Both ends of the water collection tank 607 are fixedly connected to end plates 608. One of the end plates 608 has a water outlet hole 609.

[0030] In this embodiment, the water valve 605 includes a three-way valve body 6051. The side port of the three-way valve body 6051 is connected to the connecting pipe 604, and the lower port of the three-way valve body 6051 is connected to the water pipe 606. A cap 6052 is fixedly connected to the upper port of the three-way valve body 6051. A push rod 6053 is slidably connected to the cap 6052. The upper end of the push rod 6053 abuts against the water guide groove 301, and a sealing plug 6054 is fixedly connected to the lower end of the push rod 6053. A spring 6055 in a stretched state is connected between the cap 6052 and the sealing plug 6054. A convex ring 6056 is provided inside the three-way valve body 6051, and the sealing plug 6054 abuts against the convex ring 6056 to block water from flowing into the connecting pipe 604.

[0031] In this embodiment, a collection bucket 7 for collecting starch slurry with sand removed is placed on the fixed bracket 2, and the collection bucket 7 is located directly below the filter screen plate 503.

[0032] The working process of this starch washing device for starch production is as follows:

[0033] The starch slurry is transported to the water guide trough 301 through the conveying pipe 4. The starch slurry flows from the high point to the low point of the water guide trough 301. When the starch slurry passes through the water divider block 306, it is divided by the water divider hole 307, thus spreading horizontally throughout the entire water guide trough 301. When the starch slurry passes through the strip-shaped through hole 302, due to the difference in specific gravity between sand and starch particles, the sand settles faster in the water. Most of the sand will settle on the sealing plate 303, while the starch particles will continue to move due to the water flow. When the starch slurry reaches the lower end of the water guide trough 301, the filter screen plate 503 will filter out the remaining sand in the starch particles, further enhancing the sand removal effect.

[0034] After a period of use, the sand accumulated on the device needs to be cleaned off. At this time, the flow of starch slurry into the guide groove must be stopped first. Then, the two hydraulic rods 304 should be simultaneously retracted by a certain length, causing the sealing plate 303 to move downwards a certain distance. The valve, which is fixedly connected to the sealing plate 303 via the water outlet pipe 601 and connecting pipe 604, will also move downwards a certain distance. Under the tension of the spring 6055, the sealing plug 6054 and the push rod 6053 move upwards relative to the three-way valve body 6051. This allows water in pipe 606 to pass through three-way valve body 6051, connecting pipe 604 and outlet strip pipe 601. At this time, the water flowing out from outlet strip pipe 601 will flush the sand accumulated on the surface of sealing plate 303 downwards, allowing the sand to enter the water collection tank 607, thus cleaning the sand on sealing plate 303. As for the sand on filter screen plate 503, the fixing frame 502 and filter screen plate 503 need to be removed from the stepped square hole 308 first, and then the sand on filter screen plate 503 needs to be cleaned.

[0035] After cleaning, move the hydraulic rod 304 back up and reset it. Then, place the fixed frame 502 and the filter screen 503 back into the stepped square hole 308, and the starch slurry can be fed in again for sand washing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
