Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material crushing devices, in particular to a novel corn crusher screen ring. Background Art
[0002] A corn grinder is a device that crushes corn kernels into flour. Its working principle is as follows: corn feed is fed into the grinder through a feed system. The high-speed rotation of the rotor generates centrifugal and impact forces, breaking the corn into small particles. The crushed particles are then screened and filtered. Powder smaller than the sieve aperture passes through the screen and is discharged from the discharge port. Larger particles re-enter the rotor for crushing.
[0003] During the actual production process, corn kernels are often mixed with debris such as stones and small pieces of iron. During the crushing process, these debris are forced by the rotor to strike the screen at high speed. However, these debris cannot be crushed and their large particle size prevents them from passing through the screen. Later in the process, these debris re-enters the rotor along with the incompletely crushed corn kernels, where they are accelerated by the rotor and strike the screen again at high speed. This repeated cycle can damage the screen, shortening its service life and affecting the output particle size and crushing efficiency of the grinder. Utility Model Content
[0004] The purpose of this utility model is to overcome the above problems and propose a new type of corn crusher screen ring. To achieve the above purpose, this utility model adopts the following technical solutions:
[0005] A novel corn crusher screen ring comprises a screen ring body. A reinforcement part is provided on the inner side of the bottom of the screen ring body. The reinforcement part is provided with a plurality of grooves for clamping impurities.
[0006] As an improvement, the arc range corresponding to the reinforcement portion is smaller than 180°.
[0007] As an improvement, the reinforcement part is a plurality of cross bars provided on the inner side of the bottom of the sieve ring body. The cross bars are fixed on the sieve ring body and arranged at intervals, and gaps are left between adjacent cross bars for corn flour to pass through.
[0008] Both sides of the crossbar are fixed by arc-shaped pressure strips.
[0009] As an improvement, the sieve ring body is provided with sieve holes; the sieve ring body is provided with a plurality of mounting holes.
[0010] As an improvement, the groove is 4 cm wide and 2 cm deep.
[0011] The advantages of the present invention are:
[0012] The utility model is provided with a reinforcement part on the inner side of the screen ring. The reinforcement part can firstly improve the strength of the corresponding position of the screen ring and protect the screen ring at the corresponding position. At the same time, the reinforcement part is provided with a plurality of grooves to catch impurities and iron pieces, preventing impurities from re-entering the rotor with incompletely crushed particles and preventing impurities from repeatedly damaging the screen ring, thereby ensuring the service life of the screen ring and ensuring that the screen holes are not damaged, thereby ensuring the output particle size and crushing effect of the crusher.

[0019] The present invention is described in detail and specifically below through specific embodiments to facilitate a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.
[0020] Example
[0021] This embodiment discloses a novel corn grinder screen ring, comprising a screen ring body 1 , wherein a reinforcement portion 2 is provided on the inner side of the bottom of the screen ring body 1 .
[0022] The reinforcement part 2 includes a plurality of cross bars 21 provided on the inner side of the bottom of the sieve ring body 1. The cross bars 21 are fixed on the sieve ring body 1 and arranged at intervals. Gaps 22 for corn flour to pass through are reserved between adjacent cross bars 21.
[0023] The two sides of the crossbar 21 are fixed by arcuate beadings 23. A groove 24 for catching impurities is provided on the reinforcement 2. The width of the groove 24 is about 4 cm and the depth is about 2 cm.
[0024] The arc range corresponding to the reinforcement part 2 on the screen ring body 1 is less than 180°, and the grooves 24 thereon are evenly distributed in the middle section of the reinforcement part 2 .
[0025] The sieve ring body 1 is provided with sieve holes 11 and a plurality of mounting holes 12 .
[0026] The working principle of this embodiment is described as follows:
[0027] like Figure 3 As shown, when the corn grinder is in operation, corn raw material is fed into the grinder through the feed system. The high-speed rotation of rotor 3 generates centrifugal force and impact force, breaking the corn into small particles. The crushed particles are screened and filtered by screen ring body 1. Powder smaller than the sieve holes passes through the screen ring and settles downward under the action of gravity, and is discharged from the discharge port.
[0028] Larger particles gather at the bottom of the sieve body 1. The feed piece 31 on the rotor 3 will lift the larger particles again and feed them into the rotor 3 for secondary crushing. Without the groove 24, impurities such as stones and iron flakes would re-enter the rotor 3 and then, under the acceleration of the rotor 3, hit the sieve body 1 at high speed, causing deformation of the sieve holes 11 or damage to the sieve body 1. However, the design of the groove 24 in the present invention can prevent impurities such as iron flakes from entering the rotor 3. This prevents damage to the sieve body 1 and improves the life of the sieve body 1.
[0029] In addition, the reinforcement portion 2 of the present invention can improve the strength of the bottom of the screen ring body 2 and protect the screen ring body below.
[0030] The above detailed description of the specific embodiments of the present invention is intended to serve only as examples, and the present invention is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, equivalent changes and modifications made without departing from the spirit and scope of the present invention are intended to be encompassed within the scope of the present invention.
