Technical Field

[0001] This utility model relates to the field of starch washing technology, specifically a starch washing device for wheat 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] Since the feed inlet of most current starch washing equipment is located at the top of the equipment, such as Chinese patents with publication numbers CN220530932U and CN219052016U, the feeding position is relatively high, and manual feeding is physically demanding. This results in high labor intensity and poor practicality when there is a large demand for material screening. Utility Model Content

[0004] The purpose of this utility model is to provide a starch washing device for wheat starch production, which can lift the material from a low position to the feed inlet of the screening device, and with the help of a movable structure, the material can be pre-screened during the lifting process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a starch washing device for wheat starch production, comprising a base and a screening machine housing, wherein lifting mechanisms are provided on both the left and right sides of the screening machine housing;

[0006] Two connecting plates are fixed to the front surface of the screening machine casing. Multiple arc-shaped sections are provided on the surface of the connecting plates. A collection shell is provided on the front side of the screening machine casing. Extension plates are fixed to both the left and right sides of the collection shell surface. Rollers are rotatably connected to the surface of the extension plates, and the rollers are slidably connected to the surface of the connecting plates. A movable structure for use with a lifting mechanism is installed on the surface of the collection shell. A screen plate is fixed to the inner wall of the collection shell.

Multiple first cylinders are fixed to the surface of the collection shell. One end of each first cylinder penetrates the collection shell and is fixed with a push plate.

[0007] In a preferred embodiment of the starch washing device for wheat starch production according to this utility model, the lifting mechanism includes a side plate, which is fixedly connected to the surface of the screening machine housing. A servo motor is fixed to the top of the side plate, and the output shaft of the servo motor passes through the side plate and is fixed with a lead screw. The bottom end of the lead screw is rotatably connected to the surface of the base, and a sliding sleeve is threadedly connected to the surface of the lead screw. A folded rod is fixed to the surface of the sliding sleeve.

[0008] As a preferred embodiment of the starch washing device for wheat starch production according to this utility model, the movable structure on the surface of the collection shell includes a movable groove, a slider, and a spring. The movable groove is opened on the left and right sides of the surface of the collection shell. There are two sliders. The sliders are slidably connected to the inner wall of the movable groove. One end of the spring is fixedly connected to the surface of the slider, and the other end of the spring is fixedly connected to the inner wall of the movable groove. One end of the folded rod is fixedly connected to the surface of the slider.

[0009] In a preferred embodiment of the present invention, a starch washing device for wheat starch production is provided, wherein a guide plate is fixed to the surface of the side plate, a convex plate is fixed to the surface of the sliding sleeve, a sliding groove is provided on the surface of the guide plate, the convex plate is slidably connected to the surface of the sliding groove, and the bottom of the guide plate is fixedly connected to the top of the base.

[0010] In a preferred embodiment of the starch washing device for wheat starch production according to this utility model, a second cylinder and a third cylinder are fixed on both the left and right sides of the surface of the collecting shell.

[0011] As a preferred embodiment of the starch washing device for wheat starch production according to this utility model, a guide plate is fixed below the inner wall of the screening machine casing, and the guide plate is designed with an angled inclined structure.

[0012] In a preferred embodiment of the starch washing device for wheat starch production according to this utility model, a baffle plate is fixed to the top of the mounting frame, and the top of the baffle plate is higher than the top of the screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

After the material enters the collecting shell, the starch material can achieve a preliminary screening effect on the screen plate surface. The lifting mechanism can drive the collecting shell upwards. During this process, the cooperation of the rollers, connecting plate, and arc-shaped part, along with the movable structure, can drive the collecting shell to reciprocate back and forth, thereby improving the screening effect of the starch on the screen plate surface. This achieves pre-screening treatment, thereby reducing the workload of subsequent screens and improving screening efficiency. Attached Figure Description

Detailed Implementation

[0022] Please see Figure 1-6 A starch washing device for wheat starch production includes a base 1 and a screening machine shell 2, with lifting mechanisms 3 provided on both the left and right sides of the screening machine shell 2.

[0023] The inside of the screening machine casing 2 is used to hold the material to be screened, and the lifting mechanism 3 allows the height of the collection shell 6 to be adjusted.

[0024] Two connecting plates 4 are fixed to the front surface of the screening machine casing 2. Multiple arc-shaped sections 5 are provided on the surface of the connecting plates 4. A collection shell 6 is provided on the front side of the screening machine casing 2. Extension plates 7 are fixed to both the left and right sides of the surface of the collection shell 6. Rollers 8 are rotatably connected to the surface of the extension plates 7, and the rollers 8 are slidably connected to the surface of the connecting plates 4. A movable structure for use with the lifting mechanism 3 is installed on the surface of the collection shell 6. A screen plate 12 is fixed to the inner wall of the collection shell 6. A mounting frame 13 is fixed to the inner wall of the screening machine casing 2. Vibration motors 14 are fixed on both the left and right sides of the bottom of the 3. Screens 15 are fixed on the surface of the mounting frame 13. Two feed inlets are opened on the top of the screening machine shell 2. Two boxes 16 are hinged to the surface of the screening machine shell 2. The upper box 16 is located above the screen 15. The surface of the collection shell 6 is slidably connected with a first baffle 22 and a second baffle 24. Multiple first cylinders 19 are fixed on the surface of the collection shell 6. One end of the first cylinder 19 passes through the collection shell 6 and is fixed with a push plate 20. There are two push plates 20.

[0025] The collection shell 6 is used to directly add starch material. Since the height of the collection shell 6 is lower than the feed inlet of the screening machine shell 2, the area where operators need to lift the material is reduced, thus reducing labor intensity. After the material enters the collection shell 6, the starch material can achieve a preliminary screening effect on the surface of the screen plate 12. The lifting mechanism 3 can drive the collection shell 6 upward. During this process, the roller 8, in conjunction with the connecting plate 4 and the arc-shaped part 5, and the movable structure, can drive the collection shell 6 to reciprocate back and forth, thereby improving the screening effect of the starch on the surface of the screen plate 12, thus achieving pre-screening treatment, reducing the workload of the subsequent screen 15, and improving screening efficiency. When the collection shell 6 is lifted to the alignment with the screening... When the feed inlet is opened on the surface of the casing 2, the first baffle 22 moves upward and the second baffle 24 moves downward, so that the collection shell 6 can be connected to the feed inlet. At this time, multiple first cylinders 19 can be activated so that the push plate 20 can push the screened material directly into the screening machine casing 2 through the feed inlet. The screened starch can fall directly below the screen 15, while some unscreened starch and fine sand will enter above the screen 15. At this time, the vibration motor 14 is started, which can drive the screen 15 to vibrate, thereby performing formal screening of the starch. Finally, the screened starch will fall below the screen 15, while the fine sand will remain on the surface of the screen 15. Opening the box door 16 can collect the fine sand and starch.

[0026] Furthermore, the lifting mechanism 3 includes a side plate 301, which is fixedly connected to the surface of the screening machine housing 2. A servo motor 302 is fixed to the top of the side plate 301. The output shaft of the servo motor 302 passes through the side plate 301 and is fixed with a lead screw 303. The bottom end of the lead screw 303 is rotatably connected to the surface of the base 1. A sliding sleeve 304 is threadedly connected to the surface of the lead screw 303. A folded rod 305 is fixed to the surface of the sliding sleeve 304.

[0027] When the servo motor 302 starts, it can drive the lead screw 303 to rotate, so that the sliding sleeve 304 can be affected by the thread and start to move up and down on the surface of the lead screw 303. Furthermore, the sliding sleeve 304 can also drive the movable structure through the folded rod 305 to move the collecting shell 6 together, thereby achieving the effect of changing the height position of the collecting shell 6.

[0028] Furthermore, the movable structure on the surface of the aggregate shell 6 includes a movable groove 9, a slider 11, and a spring 10. The movable groove 9 is opened on the left and right sides of the surface of the aggregate shell 6. There are two sliders 11. The sliders 11 are slidably connected to the inner wall of the movable groove 9. One end of the spring 10 is fixedly connected to the surface of the slider 11, and the other end of the spring 10 is fixedly connected to the inner wall of the movable groove 9. One end of the folded rod 305 is fixedly connected to the surface of the slider 11.

[0029] When the roller 8 contacts the arc-shaped part 5, causing the collection shell 6 to move away from the screening machine shell 2, the slider 11 will slide on the inner wall of the movable groove 9. At the same time, the spring 10 will be compressed, so that when the roller 8 stops contacting the arc-shaped part 5, the spring 10 can rebound, thereby ensuring that the collection shell 6 can move back towards the location of the screening machine shell 2, so that the collection shell 6 can achieve a reciprocating movement effect during the rising or falling process.

[0030] Furthermore, a guide plate 307 is fixed to the surface of the side plate 301, a protruding plate 306 is fixed to the surface of the sliding sleeve 304, a sliding groove is provided on the surface of the guide plate 307, the protruding plate 306 is slidably connected to the surface of the sliding groove, and the bottom of the guide plate 307 is fixedly connected to the top of the base 1.

[0031] When the sliding sleeve 304 moves, it will drive the convex plate 306 to slide together on the inner wall of the groove, so that the sliding sleeve 304 can get a guiding effect, thereby improving the stability of the sliding sleeve 304 during movement.

[0032] Furthermore, a second cylinder 21 and a third cylinder 23 are fixed on both sides of the surface of the aggregate shell 6. One end of the second cylinder 21 is fixedly connected to the surface of the first baffle 22, and one end of the third cylinder 23 is fixedly connected to the surface of the second baffle 24.

[0033] When the second cylinders 21 on both sides are started, they can drive the first baffle 22 to move upward, while when the third cylinders 23 on both sides are started, they can drive the second baffle 24 to move downward, so that the collection shell 6 can be connected to the feed port on the surface of the screening machine shell 2, so that the first baffle 22 and the second baffle 24 do not need to be manually operated.

[0034] Furthermore, a guide plate 17 is fixed to the lower part of the inner wall of the screening machine casing 2. The guide plate 17 has an angled inclined structure design.

[0035] By setting the guide plate 17, the sieved starch can be more easily gathered at the lower box door 16 by following the inclined guide plate 17, making it easier for the operator to take out the starch.

[0036] Furthermore, a baffle plate 18 is fixed to the top of the mounting frame 13, and the top of the baffle plate 18 is higher than the top of the screen 15.

[0037] The baffle plate 18 can limit the top left and right sides of the screen 15 to prevent starch and fine sand from entering the top of the mounting frame 13, thus preventing some materials from being screened.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
