DETAILED DESCRIPTION

[0025] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a raw material filtering device for processing agricultural by-products, comprising:

[0027] A bracket 1 is provided with a box body 2, and a drain pipe is provided on the box body 2. The drain pipe is located at the bottom of the box body 2 so as to discharge the sewage in the box body 2 and also facilitate the subsequent discharge of the sewage after cleaning the inside of the box body 2.

[0028] The filter assembly is one of the core components of the system, and its design is to efficiently complete the cleaning and filtering tasks of raw materials (such as wheat particles and corn particles). The assembly is mainly composed of key parts such as a semicircular mesh cover 11, a mesh plate 8, a rotating rod 9, a motor 3 and a spiral blade 10.

[0029] The semicircular mesh cover 11 is firmly fixed inside the box 2, and a semi-enclosed space is formed at the bottom. Two mesh plates 8 are connected to its upper end, and the two mesh plates 8 are arranged in parallel. The clean water is located above the mesh plates 8, which can effectively prevent the raw materials from being stirred and floating away from the semicircular mesh cover 11 during the cleaning process, thereby ensuring the cleaning effect. At the same time, the aperture design of the mesh plates 8 is reasonable, which can allow water to pass through and prevent raw material particles from falling into the water.

[0030] A rotating rod 9 is coaxially arranged inside the semicircular mesh cover 11, and one end of the rotating rod 9 is fixedly connected to the output end of the motor 3. The motor 3 is a stepping motor, and when the motor 3 is started, it drives the rotating rod 9 to rotate at a stable speed.

[0031] A discharge elbow 4 is cleverly provided through the side wall of the box body 2, and the discharge elbow 4 is not only fixedly connected to the box body 2, but also coaxially and fixedly connected to the semicircular mesh cover 11. Such a design allows the cleaned and filtered raw materials to be discharged smoothly through the discharge elbow 4, which not only ensures the continuity of the discharge, but also avoids the problem of clogging of the raw materials during the discharge process. It is worth noting that the bending design of the discharge elbow 4 also takes into account the smoothness of the discharge and the convenience of the operator, making the entire discharge process more efficient and smooth.

[0032] The spiral blades 10 used in conjunction with the semicircular mesh cover 11 are fixed on the rotating rod 9. These spiral blades 10 not only extend into the discharge elbow 4, but can also effectively transport the raw materials from the semicircular mesh cover 11 to the discharge elbow 4 during the rotation process, ensuring the smooth discharge of the raw materials. At the same time, the stirring effect of the spiral blades 10 can further promote the cleaning and filtering effect of the raw materials, making the raw materials cleaner and purer.

[0033] The spiral blade 10 is mounted on the rotating rod 9 and rotates with the rotation of the rotating rod 9. The design of the spiral blade 10 fully considers the conveying and stirring requirements of the raw materials. Its spiral shape can guide the raw materials to move along the inner wall of the semicircular mesh cover 11 in the axial direction, and continuously stir the raw materials during the movement so that they are fully in contact with the clean water, thereby achieving the purpose of cleaning. At the same time, the stirring action of the spiral blade 10 can also make impurities such as sand in the raw materials fall into the water below through the mesh of the semicircular mesh cover 11, while the weeds or empty shell particles in the raw materials will float on the water surface due to their low density, which is convenient for subsequent separation and removal.

[0034] The working principle of the entire filtering assembly is simple and efficient: a feed hopper 5 is installed on the box body 2, which is opposite to the semicircular mesh cover 11, and the enlarged part of the upper end of the feed hopper 5 is located above the box body 2, so as not to affect the subsequent staff's use of a scoop net to salvage floating objects; the raw material falls on the semicircular mesh cover 11 and the mesh plate 8 through the feed hopper 5, and the motor 3 is started to drive the rotating rod 9 and the spiral blade 10 to rotate, so as to transport and stir the raw material and clean the dirt and impurities on the surface of the raw material; heavier impurities such as sand fall into the water through the semicircular mesh cover 11, while weeds or empty shell particles float on the water surface; finally, the cleaned and filtered raw material is discharged from the discharge port, thereby realizing efficient cleaning and filtration of the raw material.

[0035] The feed hopper 5 is also provided with a rotating shaft 7, which not only has the task of stirring the raw materials, but also realizes synchronous rotation with the rotating rod 9 through the transmission structure. Specifically, a sprocket 13 is installed on the shaft 7 and the rotating rod 9, and is connected by a chain 12. Such a design enables the chain 12 and the sprocket 13 to be driven when the shaft 7 rotates, thereby realizing the synchronous rotation of the rotating rod 9. This synchronous rotation mechanism not only improves the operating efficiency of the entire system, but also ensures the continuous and stable processing of the raw materials in the feed hopper 5 and the box 2.

[0036] In addition, a baffle 18 is fixed in the box body 2 to isolate the chain 12 and the sprocket 13 from the raw material, so as to prevent the raw material from entering the transmission structure of the chain 12 and the sprocket 13 and affecting the transmission of the system.

[0037] A plurality of stirring rods 14 are fixed on the shaft 7, and the stirring rods 14 are arranged near the bottom of the feed hopper 5, and the plurality of stirring rods 14 are distributed in a circular array on the shaft 7, and they rotate with the rotation of the shaft 7 to fully stir and mix the raw materials. Such a design not only avoids the problem of raw material clogging in the feed hopper 5, but also improves the uniformity and fluidity of the raw materials, laying a good foundation for subsequent processing work.

[0038] The other end of the shaft 7 is fixed with a reciprocating screw 6 that rotates in the box 2. The reciprocating screw 6 is connected to the shaft 7 to achieve synchronous rotation with the shaft 7. A mounting plate 15 is installed on the reciprocating screw 6, and a scraper net 17 is installed on the mounting plate 15. A mounting block is fixed on the scraper net 17, and the mounting block is installed on the mounting plate 15 by bolts, which is convenient for disassembly, replacement or cleaning. When the reciprocating screw 6 rotates, it will drive the mounting plate 15 to move back and forth along the guide rail 16, and the scraper net 17 will also move accordingly. The two guide rails 16 are arranged in parallel on the inner wall of the box 2. The scraper net 17 pushes the floating objects and the raw materials of the empty shells toward the two ends of the box 2, so that they are concentrated at the two ends. This design not only improves the automation level of the entire system, but also facilitates the collection and cleaning work of the staff. The staff can salvage the floating objects that are pushed and gathered through the scoop net.

[0039] In summary:

[0040] The utility model has the following beneficial effects:

[0041] Efficient cleaning and filtration: The device uses a clever design of filtering components, using key components such as a semicircular mesh, mesh plate, rotating rod, motor and spiral blades to achieve efficient cleaning and filtration of raw materials (such as wheat grains and corn grains). The spiral blades can both transport the raw materials and stir them during rotation, so that they are fully in contact with clean water, effectively cleaning the dirt and impurities on the surface of the raw materials. At the same time, heavier impurities such as sand fall into the water through the mesh of the mesh, while weeds or empty shell particles float on the water surface, which is convenient for subsequent separation and removal. This design not only improves the cleaning and filtration efficiency, but also ensures the purity and quality of the raw materials.

[0042] Continuous and stable processing: The shaft and the rotating rod in the device rotate synchronously through the sprocket and chain, ensuring the continuous and stable processing of the raw materials in the feed hopper and the box. The stirring rod on the shaft fully stirs the raw materials, avoiding the problem of raw materials clogging in the feed hopper and improving the uniformity and fluidity of the raw materials. At the same time, the design of the discharge elbow allows the cleaned and filtered raw materials to be discharged smoothly, which not only ensures the continuity of the discharge, but also avoids the problem of raw materials clogging during the discharge process. This design of continuous and stable processing improves the operating efficiency and reliability of the entire system.

[0043] Floating object processing: The scraper moves back and forth to push the floating objects and empty shell materials toward the two ends of the box 2, so that they are concentrated at the two ends. This design not only improves the automation level of the entire system, but also facilitates the collection and cleaning work of the staff.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
