Abstract
Description
1. Technical field
[0002] The utility model belongs to the technical field of particle feed screening equipment, in particular to a double-drum screen for finished feed particles. (II) Background technology
[0004] Feed is a general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials, such as soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grain, feed additives, etc. my country is a major agricultural producer and a breeding country. The demand for feed is relatively high, and the production of feed has also increased accordingly. Feed screening is a very important part of the feed production process. Before the finished particles are bagged, the powder mixed in the particles needs to be screened out. The drum screen is a very widely used machine in sorting technology. It controls the sorting by the particle size and has high sorting accuracy. The existing drum screen is generally a double-layer screen with a relatively complex structure and a high production and manufacturing cost. For particles that only screen powder, it is completely a waste of resources; in addition, the existing drum screen is a single-drum design, with low powder screening efficiency and labor-consuming and time-consuming. (III) Summary of the invention
[0006] In order to make up for the deficiencies of the prior art, the utility model provides a double-drum sieve for finished feed particles which has the advantages of simple structure, easy manufacture, low cost and high powder screening efficiency.
[0007] The utility model is realized through the following technical solutions:
[0008] A double-drum screen for finished feed particles comprises a high leg and a low leg, wherein a shell placed obliquely is arranged on the top of the high leg and the low leg, and the characteristic is that two rotating shafts are penetrated through the shell in the length direction, and a drum screen is respectively mounted on the rotating shaft, and a powder outlet is arranged on the arc surface of the drum screen, and the drum screen is formed by three equally divided arcs fixed by connecting locks, and each rotating shaft is driven by a motor, a feed inlet is connected to the upper part of the shell, a powder outlet is connected to the lower part of the shell, a finished product outlet is connected to the rear end of the shell, and a baffle is arranged between the finished product outlet and the powder outlet.
[0009] An inclined material unloading lining plate is installed between the rotating shaft and the shell.
[0010] A transverse reinforcement frame is connected between the high legs and the low legs.
[0011] Vertical reinforcement frames are respectively connected between the high legs and between the low legs.
[0012] A switch plate is provided at the bottom of the powder outlet.
[0013] A material shifting plate is installed on the rotating shaft.
[0014] The utility model has the beneficial effects of quickly screening out powder in finished feed particles, having a simple structure, being easy to manufacture, being low in cost, and having a high powder screening efficiency, thereby ensuring the quality of finished feed particles and reducing the labor intensity of workers. (IV) Description of the drawings
[0016] The utility model is further described below in conjunction with the accompanying drawings.
[0017] Attached Figure 1 This is a schematic diagram of the main structure of the utility model;
[0018] Attached Figure 2 It is a side view structural schematic diagram of the utility model;
[0019] In the figure, 1 is a high leg, 2 is a low leg, 3 is a shell, 4 is a rotating shaft, 5 is a drum screen, 6 is a powder outlet, 7 is a connecting lock, 8 is a motor, 9 is a feed port, 10 is a powder outlet, 11 is a finished product outlet, 12 is a baffle, 13 is an inclined unloading liner, 14 is a horizontal reinforcement frame, 15 is a vertical reinforcement frame, 16 is a switch plate, and 17 is a material diverting plate. (V) Specific implementation methods
[0021] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a high leg 1 and a low leg 2. A housing 3 placed obliquely is provided on the top of the high leg 1 and the low leg 2. Two rotating shafts 4 are provided through the housing 3 in the length direction. A drum screen 5 is respectively installed on the rotating shaft 4. A powder outlet 6 is provided on the circular arc surface of the drum screen 5. The drum screen 5 is formed by three equally divided circular arcs fixed by a connecting lock 7. Each rotating shaft 4 is driven by a motor 8. A feed port 9 is connected to the upper part of the housing 3. A powder outlet 10 is connected to the lower part of the housing 3. A finished product outlet 11 is connected to the tail end of the housing 3. A baffle 12 is provided between the finished product outlet 11 and the powder outlet 10. An inclined material discharge lining plate 13 is installed between the rotating shaft 4 and the housing 3. A horizontal reinforcement frame 14 is connected between the high leg 1 and the low leg 2. A vertical reinforcement frame 15 is respectively connected between the high leg 1 and the low leg 2. A switch plate 16 is provided at the bottom of the powder outlet 10. A material diverter plate 17 is installed on the rotating shaft 4.
[0022] The utility model of the double drum screen for finished feed particles is adopted, two motors 8 are started to work, each motor 8 drives the rotating shaft 4 to rotate respectively, and the finished particles to be screened are poured from the feed port 9, and the finished particles enter the two drum screens 5. The rotating shaft 4 rotates to drive the two drum screens 5 to rotate. The drum screen 5 is provided with a powder outlet 6, and the diameter of the finished particles is larger than the diameter of the powder outlet 6. With the rotation and gravity, the finished particles flow out from the finished product outlet 11 at the end of the drum screen 5.
