Description

Technical Field

[0001] This utility model relates to the field of material feeder technology, specifically an adjustable material column fixed material feeder for vertical kilns. Background Technology

[0002] The material inside the vertical kiln is in the annular space formed by the kiln shell and the inner sleeve, while the feeding point of the feeding trolley is fixed on one side of the circumference.

[0003] If a traditional fixed feeder is used, the material inside the cylinder will be uneven, with one side higher than the other. Larger particles will roll forward along the feeding direction due to their greater inertia, while smaller particles will fall to the rear of the feed chute. This will result in the material surface on the side of the feeding trolley near the feeding point of the kiln being always at a high level, with more large particles, while the material surface on the opposite side of the feeding trolley near the feeding point of the kiln will always be at a low level, with more small particles. This will cause a difference in material height and particle size at the top of the kiln, which will further lead to uneven airflow in the kiln and cause uneven burning.

[0004] While a rotary distributor also maintains a consistently high material level at the feeding point, the rotation of the distributor within one cycle ensures uniform material level at all receiving points within the kiln. However, rotary distributors require high installation precision, and during operation, factors such as vibration and thermal stress can cause mechanical jamming, further hindering smooth operation.

[0005] Now, a novel adjustable material column fixed material distributor for vertical kilns is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable material column fixed distributor for vertical kilns, so as to solve the problems of large differences in material height and particle size at the kiln top as mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable material column fixing distributor for a vertical kiln, comprising a main cylinder of the distributor, a feeding chute above the main cylinder of the distributor, a material cup at the bottom of the main cylinder of the distributor, and an adjustable feeding component inside the main cylinder of the distributor that can optimize the material surface quality difference in the entire circumferential direction.

[0008] The adjustable feeding assembly includes a fixed cylinder, which is fixedly connected to the middle position of the top of the main cylinder of the feeder. An extension cylinder is provided outside the fixed cylinder. Adjustable threaded steel rods are welded to the left and right sides of the extension cylinder, and positioning nuts are sleeved on the outside of the adjusting threaded steel rods. A washer is provided at the bottom end of the positioning nut.

[0009] As a further technical solution of this utility model, the inner diameter of the extension cylinder is adapted to the outer diameter of the fixed cylinder, and the extension cylinder can slide up and down along the outside of the fixed cylinder.

[0010] As a further technical solution of this utility model, the adjusting threaded steel rod passes through the top end of the main cylinder of the material distributor and extends to the outside, and the adjusting threaded steel rod is symmetrically distributed about the vertical center line of the extended cylinder.

[0011] As a further technical solution of this utility model, the internal thread of the positioning nut is compatible with the external thread of the adjusting threaded steel rod, and the bottom end of the washer is in contact with the top end of the main cylinder of the feeder.

[0012] As a further technical solution of this utility model, a pre-drilled hole is provided inside the top of the adjusting threaded steel rod, a handle is provided above the adjusting threaded steel rod, connecting rings are welded to the front and rear ends of the bottom of the handle, the handle is covered with a rubber sleeve, a connecting bolt is inserted into the pre-drilled hole from back to front, and an anti-loosening nut is sleeved on the outside of the connecting bolt.

[0013] As a further technical solution of this utility model, the connecting bolt passes through the interior of the connecting ring, and the outer diameter of the connecting bolt is smaller than the inner diameter of the pre-drilled hole.

[0014] As a further technical solution of this utility model, a depth indicator is horizontally placed at the top of the adjusting threaded steel rod, a magnet is fixedly connected to the bottom of the depth indicator, a ruler groove is opened on one side of the depth indicator, and a scale is fixedly connected to both sides of the top of the main cylinder of the fabric feeder.

[0015] As a further technical solution of this utility model, the shape and size inside the groove are adapted to the shape and size outside the scale, and the magnet is attracted to the top of the adjusting threaded steel rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the adjustable material column fixed distributor in the vertical kiln not only realizes the function of optimizing the material height difference and particle size distribution, but also realizes the function of easy traction and height adjustment, and also realizes the function of easy observation of the actual height;

[0017] (1) By setting up an extension cylinder, adjusting threaded steel rod, positioning nut, washer, fixed cylinder and feeding chute, when in use, the feeding trolley pours the material into the feeding chute, and the material slides down into the fixed cylinder along the feeding chute. The extension cylinder, as the extension section of the fixed cylinder, can increase the flow path of the material. By restricting and guiding the material flow, the material fills the entire space of the distributor below the lower edge of the extension cylinder. Although there is still a certain accumulation height difference of the material in the extension cylinder in the cross section, the mass difference on the circumferential surface is very small because the cross section of the extension cylinder is much smaller than the cross section of the main cylinder of the distributor. The insertion depth of the adjusting threaded steel rod can be adjusted by the positioning nut, thereby adjusting the actual height of the extension cylinder. This can further optimize the mass difference of the material surface in the entire circumferential direction and realize the function of material height difference and particle size distribution.

[0018] (2) By setting a pre-drilled hole, a handle, a connecting ring, a rubber sleeve, a connecting bolt, and an anti-loosening nut, when adjusting the insertion depth of the adjusting threaded steel rod into the cylinder, the handle is installed on the top of the adjusting threaded steel rod through the connecting bolt and the anti-loosening nut. By gripping the handle, the adjusting threaded steel rod and the extension cylinder can be lifted as a whole, making it convenient to rotate the positioning nut for adjustment. The rubber sleeve can protect the hands and realize the function of easy traction and height adjustment.

[0019] (3) By setting a depth indicator, a magnetic piece, a groove and a scale, when in use, the depth indicator is attracted to the top of the adjusting threaded steel rod by the magnetic piece. As the height of the adjusting threaded steel rod changes, the relative position between the depth indicator and the scale will also change. The groove fits the scale, making it easy to read the scale value and realize the function of easy observation of the actual height. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Please refer to Figure 1-7 An adjustable material column fixing distributor for vertical kiln includes a main cylinder 1 of the distributor, a feed chute 7 is provided above the main cylinder 1 of the distributor, a material cup 18 is provided at the bottom of the main cylinder 1 of the distributor, and an adjustable feeding component is provided inside the main cylinder 1 of the distributor to optimize the material surface quality difference in the entire circumferential direction.

[0030] Please see Figure 1-7 An adjustable material column fixed distributor in a vertical kiln also includes an adjustable feeding component. The adjustable feeding component includes a fixed cylinder 6, which is fixedly connected to the middle position at the top of the main cylinder 1 of the distributor. An extension cylinder 2 is provided on the outside of the fixed cylinder 6. Adjustable threaded steel rods 3 are welded to the left and right sides of the extension cylinder 2 respectively. A positioning nut 4 is sleeved on the outside of the adjusting threaded steel rod 3. A washer 5 is provided at the bottom end of the positioning nut 4.

[0031] The inner diameter of the extension cylinder 2 is matched with the outer diameter of the fixed cylinder 6. The extension cylinder 2 can slide up and down along the outside of the fixed cylinder 6. The adjusting threaded steel rod 3 passes through the top of the main cylinder 1 of the distributor and extends to the outside. The adjusting threaded steel rod 3 is symmetrically distributed about the vertical center line of the extension cylinder 2. The internal thread of the positioning nut 4 is matched with the external thread of the adjusting threaded steel rod 3. The bottom end of the washer 5 is in contact with the top of the main cylinder 1 of the distributor. This can optimize the material surface quality difference in the entire circumferential direction.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the extension cylinder 2, as an extension of the fixed cylinder 6, can increase the flow path of the material. By restricting and guiding the material flow, the material fills the entire space of the distributor below the lower edge of the extension cylinder 2. Although there is still a certain accumulation height difference of the material in the cross section of the extension cylinder 2, the mass difference on the circumferential surface is very small because the cross section of the extension cylinder 2 is much smaller than the cross section of the main cylinder 1 of the distributor. The insertion depth of the adjusting threaded steel rod 3 can be adjusted by the positioning nut 4, thereby adjusting the actual height of the extension cylinder 2, which can further optimize the mass difference of the material surface in the entire circumferential direction.

[0033] The top of the adjusting threaded steel rod 3 has a pre-drilled hole 8. A handle 9 is provided on the top of the adjusting threaded steel rod 3. Connecting rings 10 are welded to the front and rear ends of the bottom of the handle 9. The handle 9 is covered with a rubber sleeve 11. A connecting bolt 12 is inserted from back to front into the pre-drilled hole 8. An anti-loosening nut 13 is sleeved on the outside of the connecting bolt 12. The connecting bolt 12 passes through the interior of the connecting ring 10. The outer diameter of the connecting bolt 12 is smaller than the inner diameter of the pre-drilled hole 8, which facilitates gripping and force application for adjustment.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the handle 9 is installed on the top of the adjusting threaded steel rod 3 by connecting bolt 12 and anti-loosening nut 13. By gripping the handle 9, the adjusting threaded steel rod 3 together with the extension cylinder 2 can be lifted as a whole, making it convenient to rotate the positioning nut 4 for adjustment. The rubber sleeve 11 can protect the hand.

[0035] A depth indicator 14 is horizontally placed at the top of the adjusting threaded steel rod 3. A magnet 15 is fixedly connected to the bottom of the depth indicator 14. A groove 16 is opened on one side of the depth indicator 14. A scale 17 is fixedly connected to both sides of the top of the main cylinder 1 of the material distributor. The shape and size inside the groove 16 are compatible with the shape and size outside the scale 17. The magnet 15 is attracted to the top of the adjusting threaded steel rod 3, which makes it easy to judge the height.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the depth indicator 14 is attached to the top of the adjusting threaded steel rod 3 by the magnet 15. As the height of the adjusting threaded steel rod 3 changes, the relative position between the depth indicator 14 and the scale 17 also changes. The groove 16 fits into the scale 17, making it easy to read the scale value.

[0037] Working Principle: In use, the feeding trolley first pours the material into the feeding chute 7. The material slides down the feeding chute 7 into the fixed cylinder 6. The extension cylinder 2, as an extension of the fixed cylinder 6, increases the flow path of the material. By restricting and guiding the material flow, the material fills the entire space of the distributor below the lower edge of the extension cylinder 2. Although there is still a certain accumulation height difference of the material in the cross-section of the extension cylinder 2, the mass difference on the circumferential surface is very small because the cross-section of the extension cylinder 2 is much smaller than that of the main cylinder 1 of the distributor. The insertion depth of the adjusting threaded steel rod 3 can be adjusted by the positioning nut 4, thereby adjusting the actual height of the extension cylinder 2 and further optimizing the mass difference of the material surface in the entire circumferential direction. When adjusting the insertion depth of the adjusting threaded steel rod 3, the handle 9 is installed on the top of the adjusting threaded steel rod 3 by the connecting bolt 12 and the anti-loosening nut 13. By gripping the handle 9, the adjusting threaded steel rod 3 and the extension cylinder 2 can be lifted as a whole, making it convenient to rotate the positioning nut 4 for adjustment. The rubber sleeve 11 protects the hand. The depth indicator 14 is attached to the top of the adjusting threaded steel rod 3 by the magnet 15. As the height of the adjusting threaded steel rod 3 changes, the relative position between the depth indicator 14 and the scale 17 also changes. The groove 16 fits into the scale 17, making it easy to read the scale value.
