Description

Technical Field

[0001] The utility model relates to the field of fish meal screening, in particular to a multi-stage separation fish meal and fish bone screening machine. Background Art

[0002] In the fish meal production line, we use a steamer to cook the raw fish, a press to squeeze it, and a dryer to dry it. The coarse fish meal contains a lot of impurities, including fish bones and various garbage debris, such as hemp ropes, cloth bag fragments, etc. These garbage debris need to be separated from the coarse fish meal to improve the quality of the final fish meal product. At the same time, with the development of related technologies in the aquaculture industry, different farmers have different requirements for the content of nutrients such as protein, minerals and vitamins in animal feed. As one of the main sources of animal feed, fish meal manufacturers also need to improve the quality indicators of fish meal. Therefore, we need to use a powder sifter to sieve the coarse fish meal obtained after drying in the dryer. However, the existing powder sifter can only separate the garbage debris in the coarse fish meal, but cannot separate the fish bones alone. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a multi-stage separation fish meal and fish bone screening machine to solve the current pain points in this field.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A multi-stage separation fish meal and fish bone screening machine, comprising a drum device and a collecting cover, wherein the drum device and the collecting cover are both mounted on a bracket and both are inclined, the drum device is rotatably mounted on the upper portion of the bracket, the collecting cover is fixedly mounted on the lower portion of the bracket and is located below the drum device, the drum device is composed of three sections of cylindrical screens with different mesh diameters, a collecting hopper auger is rotatably mounted in the collecting cover, a spiral blade is not mounted on the lower end of the collecting hopper auger, a first discharge hopper is arranged below the upper portion of the collecting cover, and a second discharge hopper is arranged below the lower portion.

[0006] It is further explained that the collecting hopper auger is connected to the collecting hopper motor fixedly mounted on the bracket.

[0007] It is further explained that the mesh diameter of the first section is 3mm to facilitate the rapid screening and separation of fish meal, the mesh diameter of the second section is 2.5mm to prevent some fine debris from mixing in while screening the fish meal, and the mesh diameter of the third section is 16mm to screen and separate fish bones.

[0008] It is further explained that the three sections of cylindrical screens are all composed of two halves of arched screens.

[0009] It is further explained that a feed auger is fixedly mounted on the higher end of the roller device, and the feed auger is connected to a main shaft motor fixedly mounted on the bracket.

[0010] Further description, a screening machine housing is arranged above the drum device, and the screening machine housing is divided into multiple sections and respectively slidably mounted on the bracket.

[0011] In summary, the beneficial effects of the utility model compared with the prior art are as follows: when the coarse fish meal enters the powder screening machine from the feed port, it will be transported forward with the conveying auger. Due to the inclination and rotation of the drum device, the coarse fish meal will also flip and roll together, wherein the fish meal will be screened and separated by the first two sections of the screen and fall into the collection device below, while the fish bones and garbage will continue to be transported forward. When the remaining materials are transported to the last section of the screen, the fish bones will be screened and separated and fall into the collection device below, while the garbage will continue to be transported forward with the conveying auger and eventually enter the garbage collection box at the end, which will be replaced and cleaned regularly by workers. As a result, the powder screening machine realizes multi-stage separation of fish meal, fish bones and garbage.

[0012] When the customer needs to pack fish meal and fish bones separately, the hopper motor drives the auger to reverse, and the fish meal sifted out by the first two screens will be transported to the discharge hopper below the first screen through the auger. After the fish bones are sifted out by the last screen, they cannot be transported by the auger because there are no spiral blades installed on the last auger, and fall into the discharge hopper below alone. In this way, the fish meal and fish bones can be classified, separated and collected separately. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described in detail below with reference to the accompanying drawings.

[0017] A multi-stage separation fish meal and fish bone screening machine, comprising a drum device 4 and a collecting hood 5, wherein the drum device 4 and the collecting hood 5 are both mounted on a bracket 6 and are inclined at the same angle, the drum device 4 is rotatably mounted on the upper part of the bracket 6, the collecting hood 5 is fixedly mounted on the lower part of the bracket 6 and is located below the drum device 4, the drum device 4 is composed of three sections of cylindrical screens with different mesh diameters, the first section of the screen has a mesh diameter of 3mm, which is convenient for rapid screening and separation of fish meal, the second section of the screen has a mesh diameter of 2.5mm, which prevents some fine debris from mixing in while screening the fish meal, and the third section of the screen has a mesh diameter of 2.5mm, which prevents some fine debris from mixing in while screening the fish meal. The three-stage screen has a mesh diameter of 16 mm and is used to screen and separate fish bones. The length of the first and second stages of the screen is three times that of the third stage, thereby achieving multi-stage separation of fish meal, fish bones and garbage. The three-stage cylindrical screen is composed of two half-arched screens. A feed auger 2 is fixed to the higher end of the drum device 4, and the feed auger 2 is connected to a spindle motor 1 fixedly mounted on the bracket 6. The spindle motor 1 drives the feed auger 2 to rotate, and the feed auger 2 rotates to feed the drum device 4. At the same time, the spindle motor 1 drives the drum device 4 to rotate for screening.

[0018] A collecting hopper auger 7 is rotatably installed in the collecting hood 5, and the collecting hopper auger 7 is connected to a collecting hopper motor 8 fixedly installed on the bracket 6. The lower end of the collecting hopper auger 7, that is, the end away from the collecting hopper motor 8, is not equipped with a spiral blade, that is, the collecting hopper auger under the 6mm screen of the main shaft motor 1 bracket is only a light axis, and the material cannot be transported by the auger here.

[0019] A No. 1 discharge hopper is arranged below the upper part of the collecting cover 5, and a No. 2 discharge hopper is arranged below the lower part. The fish meal separated by the first and second sieves falls into the collecting cover 5 and is transported to the No. 1 discharge hopper by the collecting hopper auger 7. The fish bones separated by the third sieve will not be transported by the collecting hopper auger 7, but directly fall into the No. 2 discharge hopper below.

[0020] A screening machine housing 3 is arranged above the drum device 4. The screening machine housing 3 is divided into multiple sections and is slidably mounted on the bracket 6 respectively, so as to ensure that the housing is fully sealed when the powder screening machine is working and to facilitate opening the interior during machine maintenance.

[0021] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
