Description
Technical Field
The invention belongs to the technical field of feed processing and recycling, and relates to technical equipment suitable for secondary recycling of feed processing powder.
Background
The saifeia agricultural science and technology development limited company (saifeia company) of inner Mongolia is a large-scale enterprise taking meat duck breeding and processing as major business, more than 3000 tens of thousands of meat ducks are sold in a year, and in addition, the meat ducks also comprise autotrophic grandparent ducks and parent ducks; thus, over 20 million tons of pellet feed need to be processed each year. However, in the process of producing and processing pellet feed, the pulverization rate of finished product materials is increased due to the reasons of large feeding fall of the finished product materials and the like, and certain difficulty and loss are caused to the breeding management.
The feeding method is obtained by summarizing the experience of the breeding industry for decades, and the feeding method by using the granulated feed has the following advantages:
1. avoiding the animals from being fed by food. The formula of the pellet feed contains various raw materials, has comprehensive nutrient components, and can prevent animals from selecting favorite feed from powdered feed containing limited nutrient components and refusing to take other nutrient components. As the pellet feed can keep uniformity in the storage, transportation and feeding processes, the feeding loss can be reduced by 8-10%.
2. The remuneration rate of the pellet feed is high. In the process of preparing the pellet feed, due to the comprehensive action of water, temperature and pressure, the pellet feed is subjected to certain physicochemical reactions to form gelatinized amyloid pellet feed, the activity of enzyme is enhanced, and the feed can be more effectively digested by fed animals and converted into weight gain. When the granulated feed is used for feeding poultry, compared with powdered feed, the conversion rate (i.e. return rate) of the feed can be increased by 10% -12%.
3. The storage and transportation are more economical. After the feed is made into granules, the bulk density of the feed is generally increased by 40-100%, so that the storage capacity is reduced, and the transportation cost is saved.
4. Good fluidity and convenient management. Many pellet feeds, especially low specific gravity moquette feeds, often stick to the silo after the addition of molasses or high fat and urea. Since the fluidity of the pellet feed is good and the sticking phenomenon is rarely generated, the pellet feed is most popular for the large-scale poultry farming using the automatic feeder.
5. Avoid the automatic grading of feed ingredients and reduce environmental pollution. In the process of storing and transporting the pulverized materials, automatic classification is easy to generate due to different volume and mass of various pulverized materials. After the granulated feed is prepared, the automatic grading of feed ingredients does not exist, the granulated feed is not easy to dust, and the pollution of air and moisture of the granulated feed is much less than that of pulverized feed in the feeding process.
6. The salmonella in the feed is killed. Salmonella is retained in tissues of the animal after ingestion by the animal; if a person eats an animal infected with Salmonella, Salmonella-infected gastrointestinal disease will result. The salmonella in the feed can be killed by adopting a method of tempering at high temperature by steam and then granulating.
Due to the advantages of the pellet feed, the pellet feed (pellet feed) is adopted for cultivation in the cultivation industry. However, in the production and processing process of the granulated feed, a certain amount of pulverized materials are contained in the granulated feed due to various reasons, and secondary screening treatment cannot be carried out during loading, so that huge losses are caused to feed production and breeding operation.
According to investigation, the problems are not only found in Saifenia but also commonly found in the whole feed processing industry, and no good solution exists up to now.
In order to overcome and solve the problems commonly existing in the feed processing industry, subject group personnel of the Seifeia company innovatively develop a technical device suitable for secondary recycling of feed processing powder through scientific thinking and multiple experiments. The technical equipment is utilized to thoroughly solve the above difficult problems commonly existing in the feed processing industry.

A processing lines suitable for feed processing powder material secondary recycle for retrieve the powder material in a plurality of finished product feed bins 1 includes: a plurality of technical equipment suitable for secondary recycling of the feed processing pulverized material share the pulverized material conveying pipeline 9, the auger 8, the feed raw material bin 11 and the auger motor 10; and is connected with a powdered material conveying pipeline 9 through a packing auger 8, as shown in figure 2-4, the series connection of 2 technical equipment suitable for secondary recycling of powdered materials in feed processing is realized.
The specific design consideration process is as follows:
a filter sieve 12 is designed and installed below the outlet of the finished product bin and used for: filtering to obtain a powdery material; the filtered pulverized material falls into a pulverized material discharging bin 13 firstly, and is conveyed to a feed raw material bin 11 through a packing auger 8 and a pulverized material conveying pipeline 9 for being processed into granulated feed again; and in the process of processing the pellet feed, the produced pulverized material can be recycled by continuously adopting the equipment, and the process is circulated until the pulverized material is completely recycled.
The filter sieve 12 is obliquely arranged, the included angle between the filter sieve and the horizontal plane is 45 degrees, the upper part of the filter sieve is provided with a finished product material receiving port, and the finished product material receiving port is used for receiving granulated feed containing pulverized materials falling from the outlet of a finished product bin;
the lower part of filter sieve 12 is equipped with the pellet feed export the pellet feed exit is equipped with pellet feed unloading flashboard 6, when pellet feed unloading flashboard 6 was opened, pellet feed after the filtration fell to the dumper or feed bag from the pellet feed export.
The powder filtered through the screen 12 falls into a powder discharge bin 13, said powder discharge bin 13 being substantially in the shape of an angled funnel (see fig. 3).
Considering that the filter sieve 12 may have problems in many aspects such as incomplete filtering or planar powdered material paste screen mesh in the working process, the filter sieve 12 is designed to be more scientific to vibrate, so that a 0.75KW three-phase eccentric vibrating motor 3 is installed behind the powdered material blanking bin 13. When the three-phase eccentric vibration motor 3 operates, the powdered material blanking bin and the filter sieve 12 are driven to vibrate.
The filter sieve 12 includes: the metal screen is positioned at the bottom, the frame is arranged on the periphery above the metal screen, and the metal belt is arranged above the frame; the frame is formed by welding metal plates with the thickness of 3mm, and a metal belt with the thickness of 3mm is additionally welded above the frame for durability; a layer of metal screen mesh having a mesh diameter of 1.5mm was installed at a distance of 100mm downward from the top surface of the metal belt.
In order to prevent the granular feed from overflowing in the process of passing through the metal screen mesh and damage to the frame due to vibration, the upper opening of the filter screen 12 is sealed by a nylon adhesive tape with the thickness of 5mm at the upper end of the filter screen 12, and two sides of the nylon adhesive tape are fixed at two sides of the upper end of the filter screen 12 by iron strips and screws with the width of 20 mm. The area of the metal screen is 0.5 square meter, the metal screen is inclined downwards, the angle between the metal screen and the horizontal plane is 45 degrees, the amount of the granular feed fed per hour is 30 tons, and the conveyed pulverized feed is about 0.45 ton.
The packing auger 8 is a flexible shaft packing auger with the diameter of 65 mm; the pulverized material conveying pipeline 9 is a PVC pipe with the inner diameter of 70mm and the wall thickness of 5 mm; the packing auger 8 is fixedly connected with the packing auger motor 10, and the packing auger motor 10 drives the packing auger 8 to rotate.
Why is the angle of the filter screen 12 set at 45? Through multiple tests, the subject group shows that when the angle between the metal screen and the horizontal plane is more than 45 degrees, the following results are found: the powder is not thoroughly screened, and some powder is mixed in the granulated feed; when the angle between the metal screen and the horizontal plane is less than 45 degrees, the flow velocity of the granulated feed on the metal screen is slow, the relative retention time of the granulated feed on the metal screen is long, and further certain abrasion damage is caused to the granulated feed, so that the pulverized feed quantity can be increased to a certain extent. Therefore, it is preferable to set the angle of the filter screen to 45 degrees.
Why is the vibration frequency of the three-phase eccentric vibration motor designed to be 40Hz optimal? Multiple practices prove that when the vibration frequency is higher than 40Hz, the flow speed of the granulated feed is too high, the pulverized feed is not thoroughly filtered, and the equipment structure is seriously abraded, so that the service life of the equipment is shortened; when the vibration frequency is less than 40Hz, the filtering of the pulverized material is incomplete, and the flow rate of the pellet feed is relatively slow, resulting in increased man-hours. It is therefore the best choice to design the vibration frequency of the three-phase eccentric vibration motor 3 to 40 Hz.
Because the feed processing factory processing workshop of the Saifeia company is provided with two finished product bins 1, the distance between the two finished product bins is 8 meters; therefore, through research of a subject group, the technical equipment is additionally arranged on two finished product bins 1 and connected in series, and 1 powdered material conveying pipeline 9 and the auger 8 are shared, so that the method is scientific.

Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
