Description

Technical Field

[0001] The present invention relates to the technical field of cottonseed meal feed preparation and drying, and specifically to a cottonseed meal feed preparation drying device and method. Background Art

[0002] Cottonseed meal is a by-product after cottonseed oil extraction, rich in plant protein and a small amount of fat. After detoxification and drying treatment, it can be used as an important protein source for ruminant feed and other feeds. In the process of cottonseed meal feed preparation, it mainly includes steps such as raw material screening, oil extraction and degreasing, detoxification treatment, drying and dehydration, pulverization and proportioning, etc. Among them, the drying link is a key step to ensure the quality and storage stability of cottonseed meal feed. Since the initial processed cottonseed meal usually has a high moisture content, if not dried in time, it is extremely easy to mildew and rot, resulting in nutrient loss and even toxin generation. Therefore, it is necessary to dry the cottonseed meal quickly and evenly.

[0003] At present, the drying method of cottonseed meal feed mostly uses drum drying equipment. Although this method has the advantages of continuous operation and large processing capacity, it also has obvious defects. Since the cottonseed meal itself has relatively fine particles, and there is obvious dust flying during the turning process, the materials are prone to fly and cause large raw material losses during the rolling. Moreover, usually a large amount of cottonseed meal is fed at one time, resulting in a relatively thick accumulation of the material layer in the cylinder. It is difficult for the internal materials to come into contact with the hot air in time, while the outer layer of cottonseed meal is overheated and charred, which is easy to stick to the wall or accumulate in the cylinder, and the middle layer is still wet and the drying is uneven, which is easy to cause caking or local high moisture content. Summary of the Invention

[0004] The present invention provides a cottonseed meal feed preparation drying device and method, which solves the technical problems that when drying cottonseed meal feed at present, due to the relatively fine particles of cottonseed meal and easy dust flying during the turning process, it leads to raw material flying and large losses, and a large amount of materials are fed at one time, the materials accumulate thickly in the cylinder, it is difficult for the internal part to be fully heated, while the outer layer is prone to overheating and charring, resulting in phenomena such as sticking to the wall and caking, and ultimately causing local wetness and high moisture content, affecting the drying quality.

[0014] The present invention also provides a drying method for preparing cottonseed meal feed, which is completed in cooperation with a drying device for preparing cottonseed meal feed, including the following steps: S1. Uniform feeding: First, the cottonseed meal feed is fed into the intermittent feeding part, and then the cottonseed meal is intermittently and evenly conveyed to the multi-stage drying part through the intermittent feeding part.

[0015] S2. Layered drying: The cottonseed meal flows from top to bottom in the multi-stage drying part to promote water evaporation.

[0016] S3. Temperature control adjustment: The drying temperature is controlled in sections. The first section is preheated at 40°C, the middle section is quickly dehydrated at 80°C, and the last section is kept at a low temperature and then gradually cooled.

The multi-layer annular disk structure makes the material in a flowing and thin-laying state during the drying process, significantly reducing phenomena such as caking and sticking to the wall caused by local overheating, thereby improving the drying quality.

[0019] In the present invention, through the coordinated operation of the auger, the material crushing assembly, and the material control assembly in the intermittent feeding section, the cottonseed meal feed is intermittently and quantitatively fed into the multi-stage drying section, effectively avoiding the problem of excessive material accumulation caused by a large amount of one-time feeding in traditional drying, ensuring that the material is always at a reasonable spreading thickness in the multi-stage drying section, improving the drying uniformity, and simultaneously instantaneously crushing and loosening the agglomerated cottonseed meal formed during the conveying process to ensure the thoroughness of subsequent drying treatment.

[0020] In the present invention, by setting both the feeding and drying processes in a closed space, it effectively avoids the phenomenon of dust flying generated by the fine particles of cottonseed meal feed during turning and conveying, significantly reducing the leakage and loss of materials during the drying process and improving the utilization rate of raw materials.

Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 and Figure 2 The present invention provides a technical solution: a drying device for preparing cottonseed meal feed, including a bearing bracket 1 and a cylinder body 2 with both ends open and fixedly connected to the bearing bracket 1. A cylinder cover 3 is rotatably connected to the upper end of the cylinder body 2. A multi-stage drying part 4 for automatically and evenly spreading the cottonseed meal feed and drying it in multiple stages is arranged inside the cylinder body 2. An intermittent feeding part 5 for intermittently feeding the cottonseed meal feed into the multi-stage drying part 4 is arranged on the cylinder cover 3. A driving part for driving the multi-stage drying part 4 and the intermittent feeding part 5 to run synchronously is arranged on the cylinder body 2.

[0033] Please refer to Figure 2 In this embodiment, the multi-stage drying part 4 includes a rotating shaft 41 rotatably connected to the inner cavity of the cylinder body 2 through a connecting plate and located at the axis of the cylinder body 2. The driving part is composed of a support plate fixedly connected to the lower part of the inner cavity of the cylinder body 2 and a driving motor 7 fixedly connected to the support plate by embedding. The output shaft of the driving motor 7 is fixedly connected to the lower end of the rotating shaft 41.

[0034] Please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8The intermittent feeding part 5 includes a number of L-shaped feed pipes 51 that are equidistantly passed through and fixedly connected to the cylinder cover 3 in the circumference. The upper end of the vertical section of the feed pipe 51 is connected with a feeding hopper 52, and a screw dragon 53 is rotatably connected in the transverse section of the feed pipe 51. The lower part of the outer wall of the transverse section of the feed pipe 51 is provided with a number of discharge holes 54 equidistantly along its own axial direction. The lower part of the transverse section of the feed pipe 51 is connected with a crushing component 55 for crushing the agglomerated cottonseed meal feed. The lower part of the crushing component 55 is provided with a material control component 56 for intermittently discharging the cottonseed meal feed. The upper cavity wall of the cylinder cover 3 is fixedly connected with a transmission shaft 57, and the lower end of the transmission shaft 57 is fixedly connected to the upper end of the rotating shaft 41.

[0035] See also Figure 7 and Figure 8 The crushing component 55 includes a box body 551 connected to the lower part of the transverse section of the feed pipe 51. The inner cavity of the box body 551 is symmetrically connected to two rotating columns parallel to the axis of the transverse section of the feed pipe 51. The outside of the rotating column is equidistantly connected to a number of crushing toothed disks 552. The material control component 56 includes a cylinder sleeve 561 connected to the lower part of the box body 551 and a rotating cylinder 562 rotatably connected to the cylinder sleeve 561. A discharge trough 563 is opened at the lower part of the cylinder sleeve 561, and a strip-shaped through groove 564 is symmetrically opened on the outside of the rotating cylinder 562.

[0036] See also Figure 7 and Figure 8 A rotating shaft 58 is fixedly connected to the rotating drum 562, and the rotating shaft 58 is linked to the auger 53 through a pulley 59. A ring gear 510 is fixedly connected to the upper end surface of the cylinder 2, and a gear 511 meshing with the ring gear 510 is fixedly connected to the end of the rotating shaft 58 close to the ring gear 510.

[0037] The cottonseed meal feed is fed into the feeding hopper 52 so that all the feeding hoppers 52 are filled with the cottonseed meal feed. Then the driving motor 7 is controlled to drive the rotating shaft 41 to rotate. The rotating shaft 41 then drives the transmission shaft 57 to rotate slowly. The transmission shaft 57 then drives the cylinder cover 3 to rotate. The cylinder cover 3 then drives the feed pipe 51, the crushing component 55 and the material control component 56 to rotate as a whole. During the revolution of the material control component 56, the rotating shaft 58 is driven to rotate synchronously. The rotating shaft 58 then drives the gear 511 to move on the gear ring 510, thereby causing the rotating shaft 58 to rotate. The rotating shaft 58 then drives the auger 53 to rotate through the pulley 59. The cottonseed meal feed in the feeding hopper 52 flows into the feed pipe 51 under its own weight. During the rotation of the auger 53, the cottonseed meal feed entering the feed pipe 51 is pushed to move. At this time, the auger 53 can also have a certain crushing effect on the cottonseed meal feed.

[0038] The cottonseed meal feed is pushed by the auger 53 and enters the box body 551 from the discharge hole 54. The auger 53 continuously pushes the cottonseed meal feed into the box body 551. The cottonseed meal feed continues to move downward in the box body 551, pressing against the crushing tooth disc 552 to rotate. The rotation of the crushing tooth disc 552 crushes the cottonseed meal feed. Immediately afterwards, the cottonseed meal feed flows downward further. The rotating shaft 58 rotates and drives the rotating cylinder 562 to rotate at the same time. When the rotating cylinder 562 drives the strip-shaped through groove 564 to move to a position communicating with the lower part of the box body 551, the cottonseed meal feed enters the rotating cylinder 562 through the upper strip-shaped through groove 564, and then flows out from the discharge groove 563 through the lower strip-shaped through groove 564, and finally enters the multi-stage drying part 4. When the rotating cylinder 562 drives the strip-shaped through groove 564 to rotate to be misaligned with the discharge groove 563, the feeding of the cottonseed meal feed into the multi-stage drying part 4 is paused, and the cottonseed meal feed is intermittently and quantitatively put into the multi-stage drying part 4 to avoid excessive accumulation of the feed, and at the same time, it can also indirectly ensure that the feed can be evenly spread out subsequently.

[0039] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the multi-stage drying part 4 further includes a plurality of annular discs 42 that are fixedly connected to the inner cavity of the cylinder body 2 at equal intervals along the axial direction of the cylinder body 2 by fixing columns and are slidably sleeved outside the rotating shaft 41, a plurality of spreading components 43 that are arranged at equal intervals along the axial direction of the rotating shaft 41 outside the rotating shaft 41 and are used to evenly spread the cottonseed meal feed along the radial direction of the annular disc 42, and a guiding component 44 that is arranged between the rotating shaft 41 and the inner cavity of the cylinder body 2 and is used to guide the cottonseed meal feed from top to bottom into different positions of the annular disc 42. An annular installation groove is formed in the lower part of the annular disc 42, and an electric heating wire 6 is arranged in the annular installation groove. The inclination directions of the upper end faces of adjacent annular discs 42 are opposite. The upper end face of the annular disc 42 at an odd position from top to bottom gradually inclines towards the side close to its own axis from top to bottom, and the upper end face of the annular disc 42 at an even position from top to bottom gradually inclines towards the side away from its own axis from top to bottom.

[0040] Please refer to Figure 2 and Figure 5 The spreading component 43 includes a plurality of strip-shaped plates 431 that are fixedly connected to the outer wall of the rotating shaft 41 at equal intervals in the circumferential direction and a plurality of scraping plates 432 that are fixedly connected to the lower end face of the strip-shaped plate 431 at equal intervals along the radial direction of the rotating shaft 41 and are in contact with the surface of the annular disc 42. The scraping plates 432 are inclinedly distributed, and the inclination directions of adjacent upper and lower scraping plates 432 are opposite.

[0041] Please refer to Figure 2 and Figure 3, the guiding assembly 44 includes a conical cover 441 and an annular cover 442. A conical cover 441 is fixedly connected to the outside of the rotating shaft 41 and directly below the inner diameter of the annular disk 42 at odd positions counted from top to bottom. An annular cover 442 is fixedly connected to the edge of the annular disk 42 at even positions counted from top to bottom in the inner cavity of the cylinder body 2 through a connecting rod.

[0042] By energizing the heating wire 6 to generate heat, the upper surface of the annular disk 42 is heated. The cottonseed meal feed fed in through the intermittent feeding part 5 will fall onto the upper end surface of the first annular disk 42 counted from the top. The driving motor 7 operates to drive the rotating shaft 41 to rotate. The rotating shaft 41 then drives the strip plate 431 to rotate, and the strip plate 431 then drives the scraper 432 to rotate. The inclined arrangement state of the scraper 432 is used to gradually spread the cottonseed meal feed on the surface of the annular disk 42 from the outside to the inside at this time. Additionally, the inclined surface on the surface of the first annular disk 42 counted from the top further accelerates the spreading speed of the cottonseed meal feed. The spread cottonseed meal feed is dried under the heating of the annular disk 42. At this time, the cottonseed meal feed gradually moves inward under the scraping of the scraper 432 and enters the inner diameter opening of the annular disk 42, and then the cottonseed meal feed flows downward and contacts the surface of the first conical cover 441 counted from the top.

[0043] Then it rolls outward under the conical surface of the conical cover 441 and enters the surface of the second annular disk 42 counted from the top. Since the inclined directions of the adjacent scrapers 432 above and below are opposite, the scraper 432 in the second spreading component 43 counted from the top will scrape the cottonseed meal feed to move along the surface of the annular disk 42 from the inside to the outside when rotating. Additionally, the upper end surface of the annular disk 42 at even positions counted from top to bottom gradually inclines away from its own axis from top to bottom. The inclined surface of the annular disk 42 can be used to accelerate the spreading speed of the cottonseed meal feed again, making the cottonseed meal feed gradually spread again and enabling the cottonseed meal feed to be dried again. At this time, the cottonseed meal feed on the surface of the annular disk 42 finally flows outward to the edge position of the annular disk 42 under the scraping of the corresponding scraper 432, and then the cottonseed meal feed falls into the annular cover 442 and flows inward under the inclined surface of the annular cover 442 and enters the surface of the next annular disk 42. Then the next annular disk 42 repeats the step of evenly spreading the cottonseed meal feed from the outside to the inside on the first annular disk 42 counted from the top, and the cottonseed meal feed can be dried again.

[0044] The cottonseed meal feed passes through the surfaces of the longitudinally distributed annular disks 42 from top to bottom in sequence and is evenly spread along the radial direction on the surface of each stationary annular disk 42, thereby performing multi-stage drying treatment on the cottonseed meal feed to ensure more thorough drying.

[0045] In addition, the present invention also provides a method for preparing and drying cottonseed meal feed, including the following steps: S1. Uniform feeding: First, the cottonseed meal feed is fed into the intermittent feeding part 5, and then the cottonseed meal is intermittently and evenly conveyed to the multi-stage drying part 4 through the intermittent feeding part 5.

[0046] S2. Layered drying: The cottonseed meal flows from top to bottom in the multi-stage drying section 4 and is evenly spread on the surface of each annular disk 42 to promote water evaporation.

[0047] S3. Temperature control adjustment: The drying temperature is controlled in sections. The first section is preheated at 40°C, the middle section is quickly dehydrated at 80°C, and the last section is kept at a low temperature and then gradually cooled.

[0048] S4. Discharge and cooling: The dried cottonseed meal is cooled to room temperature in the cooling section and then enters the subsequent processing link.
