Description

Technical Field

[0001] This invention relates to the field of steel preparation technology, and in particular to a screw feeder for preparing high-quality steel. Background Technology

[0002] A steel processing screw feeder is a device used for conveying and feeding steel. It consists of a screw conveyor, which is typically a helical metal tube with a helical shaft inside. When the helical shaft rotates, the steel is propelled forward along the helical tube.

[0003] Screw feeders may encounter the following problems when conveying steel scrap: 1. Excessively large scrap particles: If the scrap particles are too large, the screw feeder may be unable to convey the scrap smoothly, causing blockage or jamming. 2. Impurities in the scrap: Steel scrap may contain impurities such as nails and screws, which may jam the screw feeder, preventing normal operation. 3. Excessively high moisture content in the scrap: If the moisture content of the steel scrap is too high, the screw feeder may be unable to convey the scrap smoothly, causing blockage or jamming. 4. Excessively sticky scrap: Excessively sticky steel scrap may be unable to convey the scrap smoothly, causing blockage or jamming. Therefore, a screw feeder for high-quality steel production is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] To address the issues of excessive impurities, oversized fragments, and high moisture content in slag, which prevent the screw feeder from conveying the screw smoothly, causing blockages or jamming, this invention provides the following technical solution:

[0006] A screw feeder for producing high-quality steel includes a screw feeder assembly comprising a conveying housing, one end of which has a feed end, a conveying motor at the feed end, and a discharge end at the other end. A connecting sleeve is provided at the discharge end, and a conveying shaft is connected to the output shaft of the conveying motor, the conveying shaft being connected to a connecting sleeve on the connecting sleeve.

[0007] A material guiding assembly is disposed on the feed end of the material conveying shell.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, wherein: the interior of the connecting sleeve is provided with an assembly cavity and a limiting damping groove, and the limiting damping groove is disposed on the assembly cavity.

[0010] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, wherein: one end of the conveying shaft is provided with a connecting rod, the connecting rod is connected to a limiting damping block, the limiting damping block is provided with a support rod, the support rod is set in the assembly cavity of the connecting sleeve through a support bearing, and the limiting damping block is fitted and locked in the limiting damping groove.

[0011] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, the material guiding assembly includes a feeding hopper, mounting hole, feeding chamber, baffle, slag discharge trough plate, drive motor, transmission shaft, air guide groove, cylinder, exhaust hole, support bar, air guide chamber, screening component, pad block, reset spring, baffle plate, heating shell, grid, exhaust fan, heating wire, and guide tube.

[0012] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, the feeding hopper is disposed on the feeding end of the conveying shell, the feeding hopper has a feeding cavity connected to the feeding end, the upper surface of the feeding hopper is provided with a baffle, and the top end of the feeding hopper is provided with a slag discharge trough plate.

[0013] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, the feeding hopper has a mounting hole on its side, the transmission shaft passes through the mounting hole of the feeding hopper, one end of the transmission shaft is connected to a drive motor, the drive motor is fixedly mounted on one side of the feeding hopper, and a cylinder is fixedly sleeved on the transmission shaft, the cylinder being disposed in the feeding chamber of the feeding hopper.

[0014] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, the outer surface of the cylinder is provided with a screening element, the screening element is equally spaced on the outer surface of the cylinder, the screening element includes a pad, a return spring, and a baffle, the pad is provided on the outer surface of the cylinder, and the baffle is provided on the pad through the return spring.

[0015] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, the cylinder is provided with exhaust holes at equal intervals, the drive shaft is provided with an air guide groove inside the cylinder, the drive shaft is connected to the inner wall of the cylinder through a support bar, the support bar is provided with an air guide chamber, one end of the support bar is connected to the drive shaft, and the other end of the support bar is connected to the exhaust hole.

[0016] As a preferred embodiment of the spiral feeding device for preparing high-quality steel according to the present invention, the heating shell is disposed on the other side of the feed hopper, the heating shell is provided with heating wire and exhaust fan inside, one end of the heating shell is connected to the drive shaft through a conduit, and the other end of the heating shell is provided with a grid.

[0017] The beneficial effects of the present invention are: the conveying shaft rod is connected to the limiting damping groove of the assembly cavity on the connecting sleeve by four limiting damping blocks inside it, which is beneficial to increase or decrease the space of the conveying shell of the screw feeder, making the shape of the screw feeder adjustable.

[0018] Second; Due to excessively large slag particles: If the slag particles are too large, the screw of the screw feeder may not be able to convey material smoothly, causing blockage or jamming. Slag containing impurities: Steel slag may contain impurities such as nails and screws. These impurities may jam the screw of the screw feeder, causing it to malfunction. Slag with excessive viscosity: Excessive viscosity of steel slag may also prevent the screw of the screw feeder from conveying material smoothly, causing blockage or jamming. This can damage the screw feeder blades and cause the conveying motor to stop and burn out during operation. If the screw feeder blades jam, the limit damping block connected to the conveying motor will disengage from the limit damping groove, preventing the conveying motor from burning out while idling. At this time, the screw feeder blades will also stop rotating, avoiding excessive wear on the screw feeder blades.

[0019] The beneficial effects of this invention are as follows: by introducing coarse material from the top of the feed hopper, the larger lumps in the coarse material are screened by the screening element on the rotating cylinder. Specifically, the large lumps are blocked by the baffles on the screening element that can be rotated at a small angle. With the centrifugal force of the cylinder and the return spring set on the baffle, the large coarse material is thrown out under the elastic action of the centrifugal force and the return spring, and is collected by the slag discharge trough plate on the feed hopper. This greatly reduces the situation where large coarse material enters the inside of the conveying shell and causes the spiral feeder to jam.

[0020] Second, by setting up the cylinder and screening components, the coarse material can be broken up and allowed to enter the conveying shell evenly, preventing the accumulation of coarse material and improving the efficiency of the screw feeder.

[0021] Thirdly, the cylinder has a hollow structure with an external vent hole. The drive shaft is located inside the cylinder and has an air guide groove. The drive shaft is connected to the inner wall of the cylinder through a support bar. The support bar has an air guide chamber running through it. One end of the support bar is connected to the drive shaft, and the other end is connected to the vent hole. The warm air generated by the electric heating shell will come into contact with the coarse material through the vent hole, reducing the viscosity of the coarse material and further improving the efficiency of the screw feeder. It can also reduce the viscosity of the coarse material and prevent the screw feeder from getting stuck due to the high viscosity of the coarse material. Attached Figure Description

Implementation

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example

[0035] Reference Figures 1 to 7 This embodiment of the invention provides a screw feeder for preparing high-quality steel. The screw feeder assembly 100 includes a conveying housing 101, with a feed end 102 at one end and a conveying motor 104 at the other end. A discharge end 103 is located at the other end of the conveying housing 101, and a connecting sleeve 107 is provided at one end of the discharge end 103. A conveying shaft 105 is connected to the output shaft of the conveying motor 104, and the conveying shaft 105 is connected to a connecting sleeve 106 on the connecting sleeve 107. A guiding assembly 200 is disposed on the feed end 102 of the conveying housing 101. An assembly cavity 106a and a limiting damping groove 106b are respectively formed inside the connecting sleeve 106. The limiting damping groove 106b is disposed on the assembly cavity 106a. One end of the conveying shaft 105 is provided with a connecting rod 105a, which is connected to a limiting damping block 105b. A support rod 105c is provided on the limiting damping block 105b, and the support rod 105c is disposed within the assembly cavity 106a of the connecting sleeve 106 via a support bearing 105d. The limiting damping block 105b is engaged within the limiting damping groove 106b.

[0036] like Figures 1-3 As shown, through the four internal limiting damping blocks 105b, the conveying shaft 105 and the limiting damping groove 106b of the assembly cavity 106a on the connecting sleeve 106 are engaged with each other, which can conveniently adjust the space size of the conveying shell 101 of the screw feeder, thereby giving the screw feeder an adjustable shape.

[0037] Furthermore, excessively large slag particles may prevent the screw of the screw feeder from conveying material smoothly, leading to blockages or jamming. Additionally, the steel slag may contain impurities such as nails and screws, which can jam the screw, preventing normal operation. Furthermore, excessive stickiness of the steel slag can also prevent the screw from conveying material smoothly, causing blockages or jamming. These problems can damage the screw feeder 105-1 and cause the conveying motor 104 to stop and burn out during operation. If the screw feeder 105-1 jams, the limiting damping block 105b connected to the conveying motor 104 may disengage from the limiting damping groove 106b, allowing the conveying motor 104 to run idle without burning out. In this case, the screw feeder 105-1 will also stop rotating to avoid excessive wear.

[0038] The material guiding assembly 200 includes a feed hopper 201, mounting hole 201a, feed chamber 201b, baffle 201c, slag discharge trough 201d, drive motor 202, transmission shaft 203, air guide trough 203a, cylinder 204, exhaust hole 204a, support bar 204b, air guide chamber 204b-1, screening component 205, pad block 205a, return spring 205b, baffle plate 205c, heating shell 206, grid 206a, exhaust fan 206b, heating wire 206c, and guide tube 206d. The feed hopper 201 is located on the feed end 102 of the conveying shell 101, and the feed chamber 201b of the feed hopper 201 is connected to the feed end 102. The upper surface of the feed hopper 201 is provided with a baffle 201c, and the top is provided with a slag discharge trough 201d. A mounting hole 201a is provided on the side of the feed hopper 201. A drive shaft 203 passes through the mounting hole 201a, and one end of it is connected to a drive motor 202. The drive motor 202 is fixed to one side of the feed hopper 201. A cylinder 204 is provided on the fixing sleeve of the drive shaft 203, and the cylinder 204 is disposed in the feed chamber 201b of the feed hopper 201. A screening element 205 is provided on the outer surface of the cylinder 204. The screening element 205 is evenly spaced on the outer surface of the cylinder 204 and includes a pad 205a, a return spring 205b, and a baffle 205c. The pad 205a is disposed on the outer surface of the cylinder 204, and the baffle 205c is disposed on the pad 205a through the return spring 205b. Vent holes 204a are evenly spaced on the cylinder 204. The drive shaft 203 is located inside the cylinder 204 and has an air guide groove 203a. The drive shaft 203 is connected to the inner wall of the cylinder 204 via a support bar 204b. An air guide chamber 204b-1 is formed inside the support bar 204b, one end of which is connected to the drive shaft 203, and the other end is connected to the exhaust port 204a. An electric heating shell 206 is located on the other side of the feed hopper 201, and contains an electric heating wire 206c and an exhaust fan 206b. One end of the electric heating shell 206 is connected to the drive shaft 203 via a conduit 206d, and the other end has a grille 206a.

[0039] like Figures 4-7 As shown, by introducing coarse material from the top of the feed hopper 201 and screening it through the screening element 205 on the rotating cylinder 204, larger lumps can be removed from the coarse material. Specifically, the screening process utilizes a baffle 205c on the screening element 205, which can be rotated and adjusted at a small angle, to block large objects. Due to the centrifugal force of the cylinder 204 and the return spring 205b on the baffle 205c, large pieces of coarse material are thrown out and collected by the slag discharge trough 201d on the feed hopper 201. This significantly reduces the likelihood of large pieces of coarse material entering the conveying housing 101, thus preventing the spiral feeder 105-1 from jamming.

[0040] Furthermore, by setting the cylinder 204 and the screening component 205, the coarse material can be effectively dispersed, allowing it to enter the conveying shell 101 evenly, avoiding the accumulation of coarse material, and improving the efficiency of the screw feeder.

[0041] It is worth mentioning that by designing the cylinder 204 as a hollow structure and opening an exhaust port 204a on its surface, a drive shaft 203 is installed in the internal air guide groove 203a. The drive shaft 203 is connected to the inner wall of the cylinder 204 via a support bar 204b, and an air guide chamber 204b-1 is provided through the support bar 204b. One end of the drive shaft 203 is connected to one end of the support bar 204b, and the other end of the support bar 204b is connected to the exhaust port 204a. In addition, the warm air heated by the electric heating shell 206 will come into contact with the coarse material through the exhaust port 204a, reducing the viscosity of the coarse material and further improving the efficiency of the screw feeder. This design also reduces the viscosity of coarse materials, preventing the screw feeder 105-1 from jamming due to excessive viscosity. Besides improving screw feeding efficiency and reducing coarse material viscosity, this design may also have the following effects: 1. Better coarse material dispersion: Through the design of the cylinder 204 and the screening element 205, coarse materials can be better dispersed and thus enter the conveying housing 101 evenly. 2. Prevention of coarse material accumulation: Through the air guide groove 203a of the cylinder 204 and the air guide chamber 204b-1 of the support bar 204b, coarse materials are less likely to accumulate during conveying, avoiding blockages and clogging. 3. Improved equipment stability: The support bar 204b is connected to the inner wall of the cylinder 204, providing better structural support and increasing the stability and reliability of the equipment. 4. Reduced maintenance costs: It reduces the frequency of equipment maintenance and repairs due to coarse material blockage and jamming, thereby reducing maintenance costs. In summary, this setup not only improves the efficiency of the screw feeder and the flowability of coarse materials, but also increases the stability of the equipment and reduces maintenance costs.

[0042] Working Principle: The working principle of this equipment can be summarized as follows: 1. Adjusting the size of the conveying shell: The limiting damping block 105b on the conveying shaft 105 is engaged with the limiting damping groove 106b of the connecting sleeve 106. By adjusting the position of the limiting damping block, the size of the conveying shell of the screw feeder can be increased or decreased, thereby adjusting the shape of the equipment. 2. Preventing slag blockage and jamming: If the slag particles are too large or contain impurities, the screw may not be able to convey smoothly, or even become blocked or jammed. To prevent this from happening, a screening component 205 is installed in the equipment. Large pieces of slag are blocked by a rotatable baffle 205c, and then thrown out by centrifugal force and the action of a return spring, and collected by the slag discharge trough plate 201d. This reduces the possibility of large pieces of coarse material entering the conveying shell and avoids jamming of the screw feeder. 3. Dispersing coarse materials and preventing accumulation: The design of the cylinder 204 and the screening element 205 disperses the coarse materials, allowing them to enter the conveying housing 101 evenly, preventing accumulation and improving the screw feeder efficiency. 4. Increasing equipment stability: The cylinder 204, through the air guide holes 204a and air guide grooves 203a, and the connection between the support bar 204b and the drive shaft 203, provides better structural support and increases the stability of the equipment.
