Description

Technical Field

[0001] This utility model relates to the technical field of starch production and processing, specifically to a sieving device for precipitated powder processing. Background Technology

[0002] In the processing of sediment powder, the screening stage plays a crucial role in product quality and production efficiency. Sediment powder typically originates from raw materials such as corn, potatoes, and cassava. After preliminary treatments such as grinding, filtering, and sedimentation, it enters the screening stage. Existing sediment powder processing screening equipment has a series of shortcomings: common devices often achieve screening by vibrating the entire screening body, which requires the vibrator to operate at high power, resulting in huge energy consumption and increasing production costs; after long-term use, the screening screen is easily clogged by impurities, and the traditional device's screening screen is difficult to clean, cumbersome to disassemble, and the cleaning cleanliness is poor, seriously affecting the screening effect; some screening devices can only perform single screening operations and cannot achieve multiple screening based on the diverse characteristics of sediment powder and actual production needs, resulting in inaccurate product grading and difficulty in meeting the strict particle size requirements of different fields; furthermore, some screening devices lack an effective crushing mechanism when processing agglomerated sediment powder, resulting in low powder output and further hindering the improvement of production efficiency. Therefore, it is urgent to develop a high-efficiency, energy-saving, easy-to-clean, and flexible screening device for processing sediment powder.

[0003] Application number CN202321694731.1 discloses a starch sieving device, including a sieving unit, a base, a sieve frame, and a discharge pipe. The sieve frame is located above the base, and the discharge pipe is located on the sieve frame. A blocking component is disposed on the sieving device, including a blocking element, a pushing element, and a triggering element. The blocking element is disposed on the discharge pipe, the pushing element is located on one side of the blocking element, and the triggering element is disposed on one side of the pushing element. This utility model uses a sieving device to sieve starch. By setting up the blocking component, when it is necessary to replace the container below the discharge pipe, the discharge pipe can be blocked, temporarily stopping the discharge of starch, thereby preventing starch from falling to the ground and causing waste. However, there are shortcomings. When the device is used, after sieving for a period of time, problems such as filter screen clogging will occur, which will further affect the filtration efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is a sieving device for precipitated powder processing, including a sieving component 2. An angle adjustment component 1 is installed on the top of the sieving component 2 through a shock-absorbing component 3, and a movable cleaning component 4 is fixedly installed on the top of the sieving component 2.

[0026] The mobile cleaning assembly 4 includes a pneumatic pump 401, which is fixedly mounted on one end of the outer wall of the two side limiting plates 201 via a mounting bracket 402. A push rod 403 is mounted on the end of the pneumatic pump 401, and a connecting block 404 is fixedly mounted on the end of the push rod 403. A cleaning scraper 405 is fixedly mounted between the two connecting blocks 404. The cleaning scraper 405 is located on the top of the filter screen 202, and the bottom sides of the cleaning scraper 405 are slidably mounted on the top of the two side limiting plates 201 via sliding clamps 406. The sliding clamps 406 are slidably mounted inside the limiting groove 2011 via limiting bolts 407. The pneumatic pump 401 of the mobile cleaning assembly 4 is fixed to one end of the outer wall of the limiting plate 201 via the mounting bracket 402. The pneumatic pump 401 drives the push rod 403 to extend and retract, and the push rod 403 drives the connecting blocks 404 and the cleaning scraper 405 fixed between the connecting blocks 404 to move on the top of the filter screen 201. The sliding clamps 406 on both sides of the bottom of the cleaning scraper 405 slide in the limiting groove 2011 at the top of the limiting side plate 201, and are limited by the limiting bolt 407 to ensure that the cleaning scraper 405 moves smoothly, scrapes off the impurities remaining on the filter screen, ensures the unobstructed flow of the filter screen 202, and maintains the screening efficiency.

[0027] By installing a mobile cleaning component 4 on the device, the filter mesh may become clogged after screening for a period of time, which would affect the filtration effect. At this time, the mobile cleaning component 4 can be used to clean the filter, thus ensuring the continuity of screening efficiency.

[0028] The angle adjustment assembly 1 includes a mounting base 101. A fixed support rod 102 is fixedly mounted on the top of one side of the mounting base 101, and a pneumatic lifting rod 104 is fixedly mounted on the other side of the mounting base 101. A limiting shaft 103 is fixedly mounted on the top of the fixed support rod 102, and a limiting shaft 105 is fixedly mounted on the top of the pneumatic lifting rod 104. The mounting base 101 in the angle adjustment assembly 1 serves as a basic support, and the limiting shaft 103 on the top of the fixed support rod 102 cooperates with the limiting shaft 105 on the top of the pneumatic lifting rod 104. By raising and lowering the pneumatic lifting rod 104, the height difference between it and the fixed support rod 102 is changed. By utilizing the rotation of the two limiting shafts, the angle of the screening assembly 2 can be flexibly adjusted to adapt to different screening requirements.

[0029] The screening assembly 2 includes a limiting side plate 201 and a mounting base 204. A filter screen 202 is fixedly installed between the two limiting side plates 201, and an impurity discharge pipe 203 is fixedly installed on one side of the filter screen 202.

[0030] Limiting grooves 2011 are provided on the top of the two limiting side plates 201. The vibration motors 301 of the damping component 3 are installed on both sides of the top of the mounting base 204. Through the linkage support rods 302, the limiting side plates 201 on both sides vibrate, thereby causing the filter screen 202 fixed between the limiting side plates 201 to vibrate. The precipitated powder moves on the vibrating filter screen 202. Powder smaller than the pore size of the filter screen 202 falls through the mesh and is sieved, while impurities larger than the pore size remain on the filter screen 202 and are finally discharged from the impurity outlet pipe 203.

[0031] The shock absorption assembly 3 includes a vibration motor 301 and a shock absorber 303. The vibration motor 301 is fixedly installed on both sides of the top of the mounting base 204, and the end of the vibration motor 301 is connected to the outer wall of the two side limiting plates 201 through the connecting rod 302.

[0032] The shock absorber supports 303 are installed at the top diagonal positions of the mounting base 204, and the four shock absorber supports 303 are fixedly installed on the outer walls at both ends of the two side limit plates 201.

[0033] This sedimentation powder processing and screening device mainly consists of an angle adjustment component 1, a vibration damping component 3, a screening component 2, and a moving cleaning component 4 working together to achieve efficient screening of sedimentation powder and cleaning of the filter screen. The mounting base 101 in the angle adjustment component 1 serves as the basic support, and the limiting rotating shaft 103 at the top of the fixed support rod 102 cooperates with the limiting rotating shaft 105 at the top of the pneumatic lifting rod 104. By raising and lowering the pneumatic lifting rod 104, the height difference between it and the fixed support rod 102 is changed. The rotation of the two limiting rotating shafts allows for flexible adjustment of the angle of the screening component 2 to adapt to different screening requirements and change the flow speed and direction of the sedimentation powder on the filter screen 202. The vibration motor 301 of the vibration damping component 3 is installed on both sides of the top of the mounting base 204. Through the linkage with the support rod 302, it drives the limiting side plates 201 on both sides to vibrate, thereby causing the filter screen 202 fixed between the limiting side plates 201 to vibrate. The precipitated powder moves on the vibrating filter screen 202. Powder smaller than the pore size of the filter screen 202 falls through the mesh and is sieved, while impurities larger than the pore size remain on the filter screen 202 and are eventually discharged from the impurity outlet pipe 203. At the same time, the shock-absorbing support 303 is installed at the top diagonal position of the mounting base 204 and connected to the two side limiting plates 201 to buffer and reduce the impact of device vibration on other equipment or the working environment. The pneumatic pump 401 of the moving cleaning component 4 is fixed to one end of the outer wall of the limiting plate 201 through the mounting support plate 402. The pneumatic pump 401 drives the push rod 403 to extend and retract. The push rod 403 drives the connecting block 404 and the cleaning scraper 405 fixed between the connecting blocks 404 to move on top of the filter screen 201. The sliding clamps 406 on both sides of the bottom of the cleaning scraper 405 slide in the limiting groove 2011 at the top of the limiting side plate 201 and are limited by the limiting bolt 407 to ensure that the cleaning scraper 405 moves smoothly, scrapes off the impurities remaining on the filter screen, ensures that the filter screen 202 is unobstructed, and maintains the screening efficiency. In the working process, the sediment powder processing screening device is placed in a suitable working position to ensure that the mounting base 101 is stable. According to the characteristics of the sediment powder and the screening requirements, the angle of the screening component 2 is adjusted by the angle adjustment component 1.Start the pneumatic lifting rod 104 to raise or lower it. Using the rotation of the first limiting shaft 103 and the second limiting shaft 105, adjust the screening assembly 2 to a suitable tilt angle. Check if the vibration motor 301, connecting rod 302, and shock absorber 303 of the damping assembly 3 are securely connected. Check if the pneumatic pump 401, push rod 403, cleaning scraper 405, and other components of the moving cleaning assembly 4 are functioning properly. Turn on the vibration motor 301. The vibration motor 301 drives the limiting side plate 201 and filter screen 202 to vibrate via the connecting rod 302. Place the precipitated powder to be screened onto the filter screen 202. 2. Under vibration, the precipitated powder moves continuously on the filter screen 202. Fine powder meeting the requirements falls through the filter screen 202 and is collected, while impurities remain on the filter screen 202 and gradually move towards the impurity discharge pipe 203, eventually being discharged through it. After the screening process has been running for a period of time, the pneumatic pump 401 is started. The pneumatic pump 401 drives the push rod 403 to extend, causing the cleaning scraper 405 to move on top of the filter screen 202. During its movement, the cleaning scraper 405 scrapes away the remaining impurities on the filter screen, pushing them to the edge of the device or a specific collection position. After cleaning, the pneumatic pump 401 drives the push rod 403 to retract, and the cleaning scraper 405 returns to its initial position, awaiting the next cleaning operation. The screening and cleaning steps are repeated to continuously process and screen the precipitated powder.
