Description

Technical Field

[0001] The invention belongs to the technical field of feed production, and in particular relates to an additive screening and filtering device for feed processing. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. They are used in small amounts in feed but have significant effects. Feed additives are raw materials that must be used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. In addition, in order to ensure that the particle size of feed additives is uniform and meets the usage specifications so that they can be mixed with feed, the required amount of additives needs to be screened in advance to ensure the quality of subsequent feed processing.

[0003] In the related art, conventional screening equipment is usually used to screen additives. However, in actual use, since the position between the feed port and the screen plate is usually relatively fixed, it is easy for the additives to accumulate at the fixed position of the screen plate. Moreover, some additives with strong adsorption and easy agglomeration are more likely to accumulate and are not convenient for dispersed screening, thereby reducing the screening efficiency of the screen plate for additives. At the same time, for screening equipment with a multi-layer screen plate structure, the sieve holes of the top sieve plate are most likely to be clogged by additives. If they are not cleaned in time, it will have a lasting impact on subsequent screening operations, which will not only reduce the screening efficiency, but also reduce the overall quality of the additives.

The vibration contact 41 is telescopically arranged in the through hole 42. The through hole 42 is opened at the bottom of the shell 33.

[0038] In one embodiment of the present invention, the bottom of the vibration contact 41 is made of elastic material, and the adjacent cams 34 are deflected at an angle of 180 degrees.

[0039] It should be noted that the bottom of the vibration contact 41 can be made of an elastic contact made of rubber or silicone material. When the vibration contact 41 performs high-frequency tapping on the surface of the sieve plate 44, the deformation of the elastic contact can avoid hard impact on the surface of the sieve plate 44.

[0040] In one embodiment of the present invention, the diameters of the plurality of discharge ports 23 increase from one feeding end to the other end of the auger device 21 .

[0041] In the embodiment of the present application, when the diameter of the discharge port 23 increases step by step, it can effectively balance the situation that the discharge amount of the discharge port 23 close to the feed end is greater than that of the far end, thereby improving the overall material distribution uniformity.

[0042] In one embodiment of the present invention, an output base 2 is provided at the bottom of the vibrating screen 1, the screen frame group is detachably connected to the output base 2, a shock-absorbing sealing rubber ring 35 is provided around the bottom of the multifunctional sealing top cover 4, and the multifunctional sealing top cover 4 is detachably sealed and connected to the top edge of the top screen frame 3 through the shock-absorbing sealing rubber ring 35.

[0043] Working principle: When using the feed processing additive screening and filtering device of the present invention to screen additives, the relevant personnel turn on the output base 2 to make the screen frame group perform screening vibration to form the main body of the rotary vibrating screen device as the screening part, and at the same time, turn on the driving motor 10 through the controller and drive the second bevel gear 11 and the third bevel gear 17 at both ends to rotate, so that the second bevel gear 11 is meshed with the first bevel gear 12 and drives the driving gear 14 to rotate through the first driving shaft 13, so that the transfer pipe 5 can rotate at the bottom of the multifunctional sealing top cover 4 under the meshing of the driving gear 14 and the gear ring 15;

[0044] At the same time, one side of the third bevel gear 17 meshes with the fourth bevel gear 19 to drive the auger blade 20 to rotate in the auger device 21, and the auger device 21 rotates in the top screen frame 3 along with the transfer pipe 5. When the relevant personnel pour additives from the feed hopper 6, the additives fall into the auger device 21 through the transfer pipe 5, and then are guided out from multiple discharge ports 23 along with the rotation of the auger device 21, and are spread around and on the screen plate 44 in the top screen frame 3, effectively avoiding the accumulation of additives at a fixed position to affect the overall screening effect;

[0045] The other side of the third bevel gear 17 meshes with the fifth bevel gear 24 to drive the second drive shaft 25 to rotate. The second synchronous pulley 26 set at one end of the second drive shaft 25 drives the first synchronous pulley 28 to rotate through the synchronous belt 27, thereby driving the third drive shaft 36 inside the shell 33 to rotate. At this time, under the stable support of the supporting floor 30, the stable suspension rod 22 and the stable vertical plate 32 to the shell 33, the cam 34 sleeved on the third drive shaft 36 rotates and cooperates with the roller 37 to realize that the lifting plate 38 and the lifting guide rod 39 drive the vibration contact 41 to the bottom of the shell 33 The cams 34 are reciprocatingly extended and retracted in the through hole 42. Since the two adjacent cams 34 are deflected at an angle of 180 degrees, the adjacent vibrating contacts 41 can be alternately extended and strike the surface of the sieve plate 44 alternately at high frequency, thereby effectively achieving the effect of vibrating and clearing the particles blocking the surface of the sieve plate 44, thereby ensuring the screening of additives. The clearing device 29 can rotate around the surface of the sieve plate 44 as the transfer pipe 5 rotates, and the screened additives can be discharged through the discharge ports of each layer of the sieve plate group (not shown in the figure).

[0046] In summary, the additive screening and filtering device for feed processing of the present invention: through the material spreading component and the screen plate clearing component integrated at the bottom of the multifunctional sealing bottom cover, the spreading component and the screen plate clearing component can be controlled by the main driving component to rotate synchronously with the transfer pipe during the screening process, so that the auger device can rotate and spread the added material to ensure that the material is evenly dispersed to maximize the material screening efficiency. At the same time, the clearing device controls the multiple vibration contacts distributed at the bottom to perform high-frequency flexible knocking on the top screen plate, thereby effectively vibrating and clearing the blockages on the surface of the screen plate, thereby effectively improving the screening efficiency of the additive. The driving motor with dual output ends drives the transfer pipe to rotate by the cooperation of the driving gear and the gear ring, while the third bevel gear at the other end synchronously drives the symmetrically distributed auger device and the screen plate clearing component to operate, realizing one-to-three efficient operation. The output is provided by the driving motor, so that the second driving shaft drives the third driving shaft inside the clearing device to rotate through the synchronous belt structure, and then drives the cooperation of the cam and the roller to realize the reciprocating lifting and lowering of the vibration contact along with the lifting guide rod, so as to realize the knocking effect of the vibration contact on the surface of the screen plate, and the deflection angle between adjacent cams is set to 180 degrees, which can effectively realize the alternating extension and knocking of multiple vibration contacts at the bottom, further increasing the overall clearing effect, and the elastic material can reduce the impact on the screen plate through deformation to avoid damage to the screen plate, thus ensuring the screening of feed. The material spreading component composed of auger blades, in conjunction with the discharge port opened at the bottom of the auger device, can effectively realize the surrounding uniform spreading of additives, and the setting of the discharge port with increasing caliber can further improve the uniform spreading effect of additives along with the auger blades.
