Description

Technical Field

[0001] This utility model relates to the field of cottonseed oil pretreatment technology, specifically to a planar rotary grading sieve for cottonseed oil pretreatment. Background Technology

[0002] Cottonseed oil, extracted from cottonseeds, comes in several varieties, including pressed cottonseed oil, solvent-extracted cottonseed oil, genetically modified cottonseed oil, crude cottonseed oil, and refined cottonseed oil. It is darker red in color than other oils. After refining, it is suitable for human consumption and contains a large amount of essential fatty acids, making it ideal for mixing with animal fats. However, consuming crude cottonseed oil can damage spermatogenic cells, leading to azoospermia and infertility.

[0003] During cottonseed oil processing, cottonseeds require pre-treatment screening to remove impurities. Existing flat rotary screens for cottonseed oil production typically involve direct material feeding or manual addition, which makes precise quantitative addition difficult. This often results in excessive material being added at once, leading to insufficient and uneven screening, negatively impacting the screening effect and ultimately reducing the quality and efficiency of cottonseed oil production.

Then, the material enters the screening box through the discharge hose. This achieves the effect of quantitative material addition, avoiding the situation where excessive material is added at one time, which can easily lead to poor screening. It ensures the uniformity and sufficiency of material screening, thereby effectively improving the quality and efficiency of cottonseed oil extraction. Furthermore, the electric push rod drives the circular block to move, allowing the circular block to slide in cooperation with the metering wheel through the slot. The volume of the metering wheel can be adjusted by the circular block, making it easy to adjust and control the material quantity according to needs, thus improving the flexibility of use.

[0032] When the material enters the screening box through the feeding hose, it first falls onto the guide shell and flows along the surface of the guide shell. At the same time, under the action of the baffle, the material can be fed from feeding channel one and feeding channel two respectively, which makes it easier to distribute the material evenly to different positions in the screening box and avoids the accumulation of material in the same position, which is conducive to further uniform and thorough screening of the material.

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0042] Please see Figure 1 - Figure 6 The present invention provides a planar rotary grading screen for cottonseed oil pretreatment, comprising: a base 1 and screening boxes 2 spaced apart on its top, the screening boxes 2 being provided with a screening mechanism that makes them sway.

[0043] A detachable cover 3 is installed on top of the screening box 2;

[0044] A mounting bracket 4 is fixedly installed on one side of the top of the base 1;

[0045] A metering cylinder 5 is fixedly installed on a mounting frame 4;

[0046] A feeding hose 6 is fixedly installed at the bottom of the surface of the metering cylinder 5 and is detachably connected to the box cover 3;

[0047] The feed hopper 7 is fixedly installed on the top of the surface of the metering cylinder 5;

[0048] A motor-8 is fixedly installed on one end face of the metering cylinder 5 and its output end is movably inserted into the metering cylinder 5. A metering wheel 9 is fixedly connected to the output end of the motor-8. The outer surface of the metering wheel 9 is adapted to the inner surface of the metering cylinder 5. The metering wheel 9 and the metering cylinder 5 are sealed together to prevent material jamming. The sealing connection technology is a prior art disclosed in this field, such as a rotary feeder valve body. For details, please refer to the prior art. It will not be described in detail here.

[0049] And an adjustment mechanism provided inside the metering cylinder 5 for adjusting the volume of the metering wheel 9, wherein the metering wheel 9 has three receiving slots.

[0050] The regulating mechanism includes:

[0051] A circular block 10 is installed inside the metering cylinder 5 and located on one side of the metering wheel 9. The outer surface of the circular block 10 is adapted to the inner surface of the metering cylinder 5.

[0052] Multiple slots 11 are formed on one end face of the circular block 10 and slide in cooperation with the metering wheel 9;

[0053] And an electric push rod 12 fixedly installed on the other end face of the metering cylinder 5, the output end of the electric push rod 12 is movably inserted into the metering cylinder 5 and rotatably connected to the circular block 10.

[0054] The technical solution provided in this embodiment is as follows: During use, material enters the metering cylinder 5 through the feed hopper 7 and falls into the receiving groove of the metering wheel 9. After a certain time (e.g., 2-3 seconds), the motor 8 drives the metering wheel 9 to rotate at a certain angle, causing the other receiving grooves of the metering wheel 9 to align sequentially with the feed hopper 7 for reloading. Then, the material inside the receiving groove of the metering wheel 9 sequentially enters the screening box 2 through the discharge hose 6. Screening is then performed by moving the screening box 2 through the screening mechanism. Therefore, the metering wheel 9 is rotated and loaded with material by the intermittent opening and closing of the motor 8 (or the motor can be used to...). The machine 8 maintains a certain rotation speed and rotates continuously, thereby achieving the effect of quantitative material addition. This avoids the situation where excessive material is added at one time, which may cause poor screening. It ensures the uniformity and sufficiency of material screening, thus effectively improving the quality and efficiency of cottonseed oil production. Furthermore, the electric push rod 12 drives the circular block 10 to move inside the metering cylinder 5, so that the circular block 10 slides in conjunction with the metering wheel 9 through the slot 11. This allows the circular block 10 to block and adjust the volume of the receiving slot of the metering wheel 9, making it easy to adjust and control the quantitative material according to needs and improving the flexibility of use.

[0055] Furthermore, a guide shell 13 corresponding to the discharge hose 6 is fixedly installed on one side of the inner wall of the screening box 2. Multiple partitions 14 are fixedly installed on the top of the guide shell 13. A discharge channel one is formed between two adjacent partitions 14, and a discharge channel two is formed between the outermost partition 14 and the inner wall of the guide shell 13.

[0056] Specifically, by setting the guide shell 13, when the material enters the screening box 2 through the feeding hose 6, the material first falls onto the guide shell 13, and with the operation of the screening mechanism, the material flows along the surface of the guide shell 13. At the same time, under the action of the partition 14, the material can be fed from the feeding channel one and the feeding channel two respectively, which makes it easier to distribute the material evenly to different positions in the screening box 2, avoids the accumulation of material in the same position, and is conducive to further uniform and sufficient screening of the material.

[0057] Furthermore, the screening agencies include:

[0058] Two screens 15 are installed in the screening box 2 from top to bottom. Two discharge ports are opened at one end of the screening box 2. The screens 15 are installed by bolts. The screen hole diameter of the lower screen 15 is smaller than that of the upper screen 15, and the screening box 2 is tilted as a whole.

[0059] A discharge shell 16 is fixedly installed at one end of the screening box 2 and corresponds to the discharge port. A material discharge chute is provided at the bottom of the screening box 2.

[0060] A feeding shell 17 is fixedly installed at the bottom of the screening box 2 and corresponds to the feeding chute;

[0061] Multiple spring support seats 18 are fixedly installed on the top of the base 1;

[0062] The screening box 2 is fixedly installed on the top of the spring support seat 18, and the driving component is provided on the base 1.

[0063] The drive components include:

[0064] Motor 219 is fixedly installed on one side of the top of base 1;

[0065] A rotating disk 20 is fixedly connected to the output end of motor 219;

[0066] And a connecting rod 21 is movably installed on the top of the rotating disk 20, one end of which is movably connected to the screening box 2.

[0067] Specifically, during screening, the material enters the screening box 2 and falls onto the upper screen 15. At the same time, the motor 21 drives the rotating disk 20 to rotate, and under the action of the connecting rod 21 and the spring support seat 18, the screening box 2 rotates, thereby achieving the function of screening cottonseeds. During the process, the material passing through the upper screen 15 falls to the lower screen 15 for further screening, which facilitates grading and screening. Finally, the screened material is discharged through the discharge shell 17, and the impurities screened on the screen 15 are discharged through the discharge shell 16. Example

[0068] Based on Embodiment 1, in this embodiment: a set of rectangular blocks 22 are fixedly installed on both sides of one end of the screening box 2, a set of electromagnets 23 are fixedly installed on both sides of the other end of the screening box 2, a set of positioning blocks 24 that are inserted into the rectangular blocks 22 are fixedly installed on both sides of one end of the box cover 3, and a set of iron blocks 25 that are magnetically connected to the electromagnets 23 are fixedly installed on both sides of the other end of the box cover 3.

[0069] The top of the lid 3 has a viewing window made of plastic, and a handle is fixedly installed on the top of the lid 3.

[0070] The technical solution provided in this embodiment is as follows: When maintaining the screen 15, the electromagnet 23 is de-energized so that it no longer attracts the iron block 25. Then, the handle is held to separate the cover 3 from the screening box 2, and the positioning block 24 is removed from the rectangular block 22. The cover 3 can then be removed to open the screening box 2 for maintenance. During installation, the cover 3 is moved to the top of the screening box 2 by holding the handle, and the positioning block 24 is inserted into the rectangular block 22. Then, the electromagnet 23 is energized to attract the iron block 25, and the cover 3 can be installed and fixed. This makes it convenient to remove the cover 3 for maintenance and improves the ease of use.

[0071] It should be noted that the electromechanical components in this device, such as motor 8, electric push rod 12, motor 19 and electromagnet 23, are all controlled by an external PLC controller. Their wiring methods and control logic are well-known technologies in the field and will not be described in detail here. Those skilled in the art can implement them based on existing technical solutions.

[0072] 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, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
