[0002] Beer is a fermented wine made from malt and water as main raw materials, hops and yeast fermentation, and contains carbon dioxide and can form foam. In the production and processing of beer, a beer processing raw material screening device is needed to facilitate the screening and impurity removal of the raw materials before processing. The screening machine is a vibrating separator used to separate powders, particles and liquid slurries, which can accurately remove excessive pollutants. The vibrating screen works by using the reciprocating vibration generated by the excitation of the vibrator.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: In view of the fact that most of the prior art uses a vibration motor to drive the screen plate to vibrate, and then the vibration machine directly contacts the screen plate to generate noise, and the screen plate is hit to generate noise, making the entire working environment in a noisy environment, affecting the physical and mental health of the workers. To solve this problem, the following technical solution is proposed:

[0032] Refer to the instruction manual Figure 1-Figure 7 , a raw material dust removal and screening equipment for beer production with a noise reduction component, such as Figure 1 and Figure 2 As shown, it comprises a base frame 1, a screening box 2 is fixedly mounted on the top of the base frame 1, a feed hopper 3 is arranged on the top of the screening box 2, a sieve plate 4 is arranged on the inner wall of the screening box 2, and a magnetic push mechanism 5 is arranged on the bottom of the sieve plate 4;

[0033] like Figure 3 and Figure 4 As shown, the magnetic push mechanism 5 includes a plurality of rollers 51 rotatably mounted on both sides of the sieve plate 4, the plurality of rollers 51 are arranged in a vertical state, the outer walls of the plurality of rollers 51 are provided with slideways 52, the inner walls of the plurality of slideways 52 are in contact with the outer walls of the rollers 51, the plurality of slideways 52 are arranged in a vertical state, the plurality of slideways 52 are fixedly mounted on the inner wall of the screening box 2, a plurality of support springs 53 are fixedly mounted on both sides of the sieve plate 4, the plurality of support springs 53 are fixedly mounted on the inner wall of the screening box 2, the plurality of support springs 53 are arranged vertically upward, and when the sieve plate 4 is subjected to force, the plurality of rollers 51 vertically move upward in the slideways 52 and compress the plurality of support springs 53 to be subjected to force.

[0034] like Figure 3 and Figure 4 As shown, a first magnet block 54 is fixedly installed at the bottom of the sieve plate 4, and the first magnet block 54 and the sieve plate 4 are arranged perpendicular to each other. A second magnet block 55 is arranged at the bottom of the first magnet block 54, and the second magnet block 55 and the first magnet block 54 are arranged corresponding to each other. When the second magnet block 55 rotates and approaches the first magnet block 54, the two magnets with the same poles repel each other, so that the second magnet block 55 pushes the first magnet block 54 upward;

[0035] like Figure 3 and Figure 4 As shown, a rotating wheel 56 is fixedly installed on one side of the second magnet block 55, and the rotating wheel 56 and the second magnet block 55 are arranged perpendicular to each other. A rotating rod 57 is fixedly installed on the inner wall of the rotating wheel 56, and the rotating rod 57 is arranged in a horizontal state. A rotating motor 58 is provided on one side of the rotating rod 57, and the rotating motor 58 is fixedly installed on the inner wall of the screening box 2. The rotating motor 58 drives the rotating rod 57 to make the rotating wheel 56 rotate in a circle, and the rotating wheel 56 drives the second magnet block 55 to rotate in a circle. A discharging plate 59 is fixedly installed on one side of the screen plate 4, and the discharging plate 59 is fixedly installed on the outer wall of the screening box 2, and the screened debris is discharged through the discharging plate 59.

[0036] like Figure 3 and Figure 5 As shown, a buffer mechanism 6 is provided at the bottom of the feed hopper 3, and the buffer mechanism 6 includes push rods 61 fixedly installed on both sides of the sieve plate 4, the two push rods 61 are arranged vertically upward, and rubber support blocks 62 are fixedly installed on the tops of the two push rods 61, and the two rubber support blocks 62 are arranged perpendicular to each other with the two push rods 61, and the tops of the two rubber support blocks 62 are arranged in a slope shape. When the sieve plate 4 is lifted up and moved upward, the sieve plate 4 drives the push rods 61 on both sides to make the rubber support blocks 62 move upward synchronously.

[0037] like Figure 3 and Figure 5As shown, a wheel ring 63 is provided on the top of the two rubber support blocks 62, and the outer walls of the two wheel rings 63 are in contact with the tops of the two rubber support blocks 62, and a push rod 64 is installed on the inner walls of the two wheel rings 63 for common rotation, and the push rod 64 is arranged in a horizontal state, so that the rubber support blocks 62 move upward and squeeze the wheel ring 63 through the top inclined surface, and then the wheel ring 63 is pushed to one side, that is, the wheel ring 63 drives the push rod 64 to deviate to one side;

[0038] like Figure 3 and Figure 5 As shown, a cover plate 65 is fixedly installed on one side of the push rod 64, and the cover plate 65 is rotatably installed at the bottom of the feed hopper 3. The cover plate 65 is arranged downwardly at an angle, and the outer wall of the cover plate 65 fits with the bottom of the feed hopper 3. A plurality of limit springs 66 are fixedly installed on the outer wall of the cover plate 65, and a plurality of limit springs 66 are fixedly installed on the outer wall of the feed hopper 3. The push rod 64 drives the cover plate 65 to rotate and compress the plurality of limit springs 66, and the cover plate 65 is separated from the bottom of the feed hopper 3, so that the material fed into the feed hopper 3 falls, that is, the material is closest to the screen plate 4 at this time, so as to prevent the material from falling from a high place on the screen plate 4 and hitting it to produce noise.

[0039] In specific implementation, the rotating motor 58 drives the rotating rod 57 to make the rotating wheel 56 rotate in a circle, and the rotating wheel 56 drives the second magnet block 55 to rotate in a circle. When the second magnet block 55 rotates close to the first magnet block 54, the two magnets with the same poles repel each other, so that the second magnet block 55 pushes the first magnet block 54 upward. When the sieve plate 4 is subjected to force, it moves vertically upward in the slideway 52 through the multiple rollers 51 and compresses the multiple supporting springs 53, that is, the sieve plate 4 moves down again after the second magnet block 55 and the first magnet block 54 move away from each other, so that the sieve plate 4 can move back and forth to generate shaking and screen the material, and the whole process prevents the sieve plate 4 from being directly contacted and generating noise;

[0040] At the same time, when the sieve plate 4 is lifted up, it drives the push rods 61 on both sides to make the rubber support block 62 move up synchronously, and then the rubber support block 62 moves up and squeezes the wheel ring 63 through the top inclined surface, and then the wheel ring 63 is pushed to one side, that is, the wheel ring 63 drives the push rod 64 to deviate to one side, and the push rod 64 drives the cover plate 65 to rotate and compress multiple limit springs 66, and the cover plate 65 is separated from the bottom of the feed hopper 3, so that the material fed into the feed hopper 3 falls, that is, the material is closest to the sieve plate 4 at this time, avoiding the material falling from a high place on the sieve plate 4 and hitting it to produce noise.

[0041] Embodiment 2: In view of the fact that the prior art cannot buffer the screened materials, causing the materials to hit the receiving hopper and generate noise when they fall, and also cannot remove the dust in the screened materials, the following technical solution is proposed to solve this problem:

[0042] like Figure 2 and Figure 6As shown, a receiving mechanism 7 is provided at the bottom of the sieve plate 4, and the receiving mechanism 7 includes a receiving hopper 71 provided at the bottom of the sieve plate 4, and the receiving hopper 71 and the bottom of the sieve plate 4 are arranged corresponding to each other, and the bottom of the receiving hopper 71 is connected to a discharge hopper 72, and the discharge hopper 72 is connected to the outer wall of the screening box 2, and the bottom of the discharge hopper 72 is arranged in a slope shape, and the material screened from the bottom of the sieve plate 4 is received by the receiving hopper 71, and discharged through the discharge hopper 72;

[0043] like Figure 6 As shown, a plurality of support plates 73 are rotatably mounted on the inner wall of the receiving hopper 71, and the plurality of support plates 73 are arranged in pairs corresponding to each other. Two support plates 73 are located at the bottom of the sieve plate 4, and the width of the two support plates 73 is the same as the width of the sieve plate 4. A sponge plate 74 is fixedly mounted on the top of the support plate 73, and pull ropes 75 are fixedly mounted on both sides of the support plate 73. The pull ropes 75 are fixedly mounted on the bottom of the sieve plate 4. When the sieve plate 4 moves upward, the pull ropes 75 are pulled to drive the support plates 73 to move upward synchronously, and then the support plates 73 drive the sponge plates 74 to deflect horizontally close to the bottom of the sieve plate 4, thereby stably catching the screened material and then sending it to the bottom of the receiving hopper 71 by turning downward.

[0044] like Figure 6 As shown, the inner wall of the receiving hopper 71 is provided with a dust filtering mechanism 8, and the dust filtering mechanism 8 includes a plurality of dust collecting cylinders 81 arranged inside the receiving hopper 71, and the plurality of dust collecting cylinders 81 are arranged in a horizontal state, and the plurality of dust collecting cylinders 81 and the plurality of supporting plates 73 are arranged parallel to each other, and the outer wall of the dust collecting cylinder 81 is provided with holes, and the material is shaken up and the dust therein is scattered by the up and down deflection of the supporting plate 73, and the negative pressure airflow suction in the plurality of dust collecting cylinders 81 absorbs the scattered dust;

[0045] like Figure 6 and Figure 7 As shown, one side of the multiple dust collection cylinders 81 is connected to multiple air pipes 82, and the bottoms of the multiple air pipes 82 are commonly connected to a water tank 83, which is fixedly installed at the bottom of the screening box 2. One side of the water tank 83 is connected to an air suction pipe 84, and the horizontal height of the air suction pipe 84 is higher than the horizontal height of the air pipe 82. A negative pressure motor 85 is provided on one side of the air suction pipe 84, and the negative pressure motor 85 is fixedly installed at the bottom of the screening box 2. The negative pressure motor 85 generates a negative pressure airflow in the water tank 83 through the air suction pipe 84, and the negative pressure airflow sucks the dust in the dust collection cylinder 81 into the water tank 83 through the multiple air pipes 82, and absorbs the dust through the water in the water tank 83 to filter the airflow.

[0046] like Figure 6 and Figure 7As shown, the bottom of the water tank 83 is connected to a drain pipe 86, which passes through the bottom of the screening box 2. A water inlet pipe 87 is arranged on one side of the drain pipe 86, which passes through the outer wall of the screening box 2. The horizontal height of the water inlet pipe 87 is higher than the horizontal height of the drain pipe 86. After the work is completed, the water containing dust in the water tank 83 is discharged by opening the drain pipe 86, and then water is introduced into the water tank 83 through the water inlet pipe 87 to flush the water tank 83 and store water again.

[0047] In specific implementation, when the sieve plate 4 moves upward, the pull rope 75 is pulled to drive the support plate 73 to move upward synchronously, and then the support plate 73 drives the sponge plate 74 to deflect horizontally close to the bottom of the sieve plate 4, so that the screened material is stably received and then sent to the bottom of the receiving hopper 71 by turning downward, and the receiving hopper 71 receives the screened material from the bottom of the sieve plate 4 and discharges it through the discharge hopper 72, thereby achieving the effect of buffering the falling material and avoiding the noise caused by the collision of the screened material;

[0048] The material is shaken up and the dust therein is dispersed by the up and down deflection of the support plate 73, and the negative pressure motor 85 generates a negative pressure airflow in the water tank 83 through the suction pipe 84. The suction force generated by the dust collection cylinder 81 connected to the negative pressure airflow absorbs the dispersed dust and is sucked into the water tank 83 with the help of multiple air pipes 82. The dust is absorbed by the water in the water tank 83 and the filtered airflow is achieved, so that the dust in the screened material is absorbed and removed.
