Description

Technical Field

[0001] The utility model relates to the technical field of spiral distributors, and more specifically, to a spiral distributor in a warehouse. Background Art

[0002] The spiral feeder is a device that evenly loads solid waste with low moisture content and easy to compact and bridge into the bin. The spiral feeder uses the rotation of the spiral to transport the material in the semicircular trough concentric with it. Due to the effects of gravity and friction on the trough wall, the material in the trough does not rotate with the spiral during movement, but moves along the trough in a sliding manner.

[0003] However, in the prior art, although it has a good distribution effect, the mixed material contains coarse aggregate and fine aggregate. When the shaft rotates, the centrifugal force and inertia generated by aggregate particles of different coarseness and fineness are different. The coarser aggregate particles are often transferred to the outer end of the distribution disk, and the finer aggregate particles are often transferred to the inner end of the distribution disk, resulting in uneven material distribution, poor material quality, and affecting the material use effect.

[0004] After searching, the Chinese patent with authorization announcement number CN215782985U discloses a spiral distributor. This structure rotates through a mixing disk. Due to the different inertia and centrifugal force of particles of different coarseness and fineness, the coarser and heavier particles fall quickly through the through-holes and then slide down through the inner wall of the mixing dish. The finer particles fall slowly through the retarding net, so that the coarse and fine particles are remixed. By adjusting the rate at which the through-holes and the retarding net pass the material during manufacturing, the originally unevenly mixed materials can be evenly mixed with coarse and fine particles.

[0005] However, in actual use, this structure separates the coarser particles from the finer particles due to the different inertia and centrifugal forces of particles of different coarseness, and then remixes them. It is difficult to ensure the uniformity of the coarseness of the mixed materials, and it is also difficult to crush the coarser particles, which affects the use effect. Utility Model Content

[0015] Technical effects and advantages of this utility model:

[0016] 1. By setting up a conveying mechanism, compared with the existing technology, the first motor is started to drive the rotating shaft to rotate, and the rotating shaft drives the auger spiral blade to rotate, so as to convey materials with finer particles and materials with coarser particles. Since the feeding point of the coarser particles is farther away, the friction and stirring between the auger spiral blade and the first motor not only conveys the materials, but also stirs the materials moderately, thereby crushing the coarser particles and improving the uniformity and fluidity of the materials. The wear-resistant layer also improves the wear resistance and extends the service life of the threaded barrel, thereby ensuring the uniformity of the material distribution, thereby improving the quality of the materials, and the operation is convenient and quick;

[0017] 2. By setting up a separation mechanism, compared with the existing technology, the material is introduced into the separation mesh cylinder inside the separation cylinder through the feed pipe, and the separation mesh cylinder is driven to rotate by the second motor. Through the rotation of the separation mesh cylinder, the coarser particles of the material are thrown out from the inside of the separation mesh cylinder by centrifugal force and inertia, so that the coarser particles of the material fall into the interior of the separation cylinder, and are transported to the interior of the discharge pipe through the filter disc. At the same time, the finer particles of the material fall into the interior of the discharge hopper through the filter disc, and are transported to the middle position of the separation cylinder through the discharge hopper, thereby separating the materials of different coarse and fine particles and transporting them to the threaded cylinders at different positions, so as to make them uniform and improve the use effect of the materials.

[0026] The conveying mechanism includes a threaded cylinder 4 arranged inside the threaded support frame 1, one end of the discharge pipe 3 is connected to the threaded cylinder 4, and a first motor 5 is fixedly arranged on one side of the threaded cylinder 4. The output end of the first motor 5 is coaxially connected to the rotating shaft 6, and an auger spiral blade 7 is sleeved on the rotating shaft 6. A conveying trough is provided at the bottom of the threaded cylinder 4, and an inclined plate 8 is provided inside the conveying trough. A total discharge pipe 9 is provided at the bottom of the inclined plate 8. At the same time, the first motor 5 is started, the first motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the auger spiral blade 7 to rotate, thereby conveying materials with finer particles and materials with coarser particles. Since the feeding point of the coarser particles is farther away, the auger spiral blade 7 not only plays the role of conveying the material, but also can moderately stir the material through the friction and stirring between the auger spiral blade 7 and the first motor 5, thereby crushing the coarser particles of the material and improving the uniformity and fluidity of the material. Then, the material is discharged through the total discharge pipe 9 on the side of the inclined plate 8, thereby ensuring the uniformity of the distribution, thereby improving the quality of the material, and the operation is convenient and quick.

[0027] Reference Figure 2-4 As shown, the interior of the separation cylinder 2 is provided with a separation mechanism, which includes a feed pipe 10 provided at the top of the separation cylinder 2, a feed hopper 11 provided at the top of the feed pipe 10, a discharge hopper 12 provided at the bottom of the separation cylinder 2, one end of the discharge hopper 12 is connected to the separation cylinder 2, a second motor 13 is fixedly provided on the top of the separation cylinder 2, a rotating rod 14 is provided at the output end of the second motor 13, a separation mesh cylinder 15 is sleeved on the rotating rod 14, the material is poured into the interior of the feed hopper 11, and then transported to the feed pipe 10 through the feed hopper 11, and then discharged through the feed pipe 10 Enter the separation net cylinder 15 inside the separation cylinder 2, and at the same time start the second motor 13 to drive the rotating rod 14 to rotate, and the rotating rod 14 drives the separation net cylinder 15 to rotate. Through the rotation of the separation net cylinder 15, the coarser particles of material are thrown out from the inside of the separation net cylinder 15 by centrifugal force and inertia and fall into the inside of the separation cylinder 2. Since the mesh holes opened around the separation net cylinder 15 can pass through the coarser particles of material, since the coarser particles of material are heavier and thus have greater inertia, the mesh holes opened at the bottom of the separation net cylinder 15 can only pass through the finer particles of material.

[0028] Reference Figure 4-5As shown, one end of the rotating rod 14 is rotatably connected to a support plate 16, and both ends of the support plate 16 are connected to the inner wall of the separation cylinder 2. One end of the rotating rod 14 is rotatably connected to a support plate 16, and both ends of the support plate 16 are connected to the inner wall of the separation cylinder 2. The inner wall of the separation cylinder 2 is provided with an anti-corrosion layer 18, and the inner wall of the threaded cylinder 4 is provided with a wear-resistant layer 19. Since the mesh diameter opened on the surface of the filter disc 17 can pass through finer particles of material, and intercept coarser particles of material, and then enter the interior of the threaded cylinder 4 farther away through the discharge pipe 3, at the same time, the finer particles of material are filtered through the bottom of the separation mesh cylinder 15 and fall onto the filter disc 17, and then fall into the interior of the discharge hopper 12 through the filter disc 17, and are transported to the middle position of the separation cylinder 2 through the discharge hopper 12. At the same time, the anti-corrosion layer 18 and the wear-resistant layer 19 extend the service life.

[0029] Working principle of this utility model:

[0030] The present invention is an internal spiral feeder. When the device is in use, the material is poured into the inside of the feed hopper 11, and then transported to the feed pipe 10 through the feed hopper 11, and then enters the separation net cylinder 15 inside the separation cylinder 2 through the feed pipe 10. At the same time, the second motor 13 is started to drive the rotating rod 14 to rotate, and the rotating rod 14 drives the separation net cylinder 15 to rotate. Through the rotation of the separation net cylinder 15, the coarser particles of the material are thrown out from the inside of the separation net cylinder 15 by centrifugal force and inertia and fall into the inside of the separation cylinder 2. Since the mesh holes opened around the separation net cylinder 15 can pass through the coarser particles of the material, the coarser particles of the material are heavier and have greater inertia. , and the mesh holes opened at the bottom of the separation net cylinder 15 can only pass through the materials with finer particles, so that the materials with coarser particles fall into the interior of the separation cylinder 2, and then pass through the filter disc 17 set in an inclined shape to transport the materials with coarser particles to the interior of the discharge pipe 3. Since the mesh diameter opened on the surface of the filter disc 17 can pass through the materials with finer particles, the materials with coarser particles are intercepted, and then enter the interior of the threaded cylinder 4 farther away through the discharge pipe 3. At the same time, the materials with finer particles are filtered at the bottom of the separation net cylinder 15 and fall onto the filter disc 17, and then fall into the interior of the discharge hopper 12 through the filter disc 17, and are transported to the middle position of the separation cylinder 2 through the discharge hopper 12;

[0031] At the same time, the first motor 5 is started, and the first motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the auger spiral blade 7 to rotate, thereby conveying materials with finer particles and materials with coarser particles. Since the feeding point of the coarser particles is farther away, the auger spiral blade 7 can not only convey the materials through the friction and stirring between the auger spiral blade 7 and the first motor 5, but also stir the materials moderately, thereby crushing the coarser particles and improving the uniformity and fluidity of the materials, and then discharge them through the total discharge pipe 9 on the side of the inclined plate 8, thereby ensuring the uniformity of the material distribution, thereby improving the quality of the material, and convenient and quick operation. At the same time, the anti-corrosion layer 18 and the wear-resistant layer 19 extend the service life.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
